Evolution of liver transplantation in the metabolic dysfunction-associated steatotic liver disease era: Tracking impact through time. World J Transplant 2024; 14:98718. [PMID: 39697455 PMCID: PMC11438936 DOI: 10.5500/wjt.v14.i4.98718] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2024] [Revised: 08/19/2024] [Accepted: 08/23/2024] [Indexed: 09/20/2024] Open
Abstract
Liver transplantation (LT) for metabolic dysfunction-associated steatotic liver disease (MASLD) is increasing globally due to rising rates of obesity and metabolic syndrome, posing significant challenges. MASLD patients typically present with advanced age, higher body mass index (BMI), and metabolic comorbidities such as diabetes, hypertension, and dyslipidemia. Comprehensive pre-transplant evaluations are crucial for assessing surgical risks and preparing patients for transplantation. MASLD patients with higher BMI may experience longer operative times, potentially affecting intraoperative outcomes. In the months following LT, MASLD recipients face persistent challenges, including a higher incidence of metabolic syndrome and cardiovascular events compared to non-MASLD recipients. However, survival rates at 1-, 3-, and 5-years post-LT do not markedly differ from other etiologies, indicating comparable surgical outcomes. Optimizing outcomes in MASLD patients undergoing LT demands a multidisciplinary approach from pre-transplant assessment to post-transplant care. Strategies must address metabolic comorbidities, manage cardiovascular health, and monitor steatosis recurrence, which can be exacerbated by obesity and diabetes. This approach aims to mitigate long-term graft complications and mortality risks, ultimately enhancing transplant success and patient well-being. Continued research is essential to refine these approaches and meet the evolving challenges posed by MASLD as a leading indication for LT worldwide.

Wang KM, Gelabert H, Jimenez JC, Rigberg D, Woo K. Association of Frailty with Postoperative Survival and Outcomes Following Hemodialysis Vascular Access Creation. Ann Vasc Surg 2024; 106:184-188. [PMID: 38815906 DOI: 10.1016/j.avsg.2024.03.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Revised: 11/21/2023] [Accepted: 03/10/2024] [Indexed: 06/01/2024]
Abstract
BACKGROUND The literature suggests that for patients to experience the purported advantages of an arteriovenous fistula (AVF) over arteriovenous graft (AVG), a minimum survival of 18 months is required. With the vascular access guideline shift away from "Fistula First" toward shared decision making, patient survival after vascular access creation is a major factor to consider in optimal access selection. The objective of this study is to examine outcomes of vascular access in patients with short survival and factors associated with short survival, including frailty. METHODS We performed a retrospective review of 200 access procedures performed between August 2018 and November 2020 at a single institution. Maturation was defined as the date when the surgeon deemed the access ready to be used for dialysis. A modified Risk Analysis Index (RAI) score was used to calculate frailty. RESULTS Within 3 years after access creation, 55 (27.5%) patients were recorded as dead (mortality within 3 years of access creation [3YMORT]). In the 3YMORT group, 5 did not follow-up with the surgeon prior to death and 22/34 (65%) of AVF versus 15/16 (94%) of AVGs were deemed mature prior to death (P = 0.03). Of the accesses that matured, the median days to maturation for AVF was 69 (interquartile range [IQR] 53, 87) versus 28 (IQR 18, 32) for AVG (P < 0.001). Patients in the 3YMORT group were older (70.6 vs. 63.4, P = 0.004) and had a lower body mass index (24.8 vs. 27.4, P = 0.03). Patients in the 3YMORT group had higher prevalence of dysrhythmia (35% vs. 15%, P = 0.002), chronic obstructive pulmonary disorder (20% vs. 10%, P = 0.048) and dialysis dependence at the time of access creation (91% vs. 75%, P = 0.01). There was no significant difference in sex, white race, Hispanic ethnicity, coronary artery disease, congestive heart failure, previous coronary artery bypass graft or percutaneous coronary intervention, diabetes, hypertension, and peripheral arterial disease between the 2 groups. The 3YMORT group had a significantly higher prevalence of frailty (78% vs. 49%, P = 0.0002). Patients categorized as frail by the RAI had a significantly higher risk of 3YMORT (odds ratio [OR] 3.74, 95% confidence interval [CI] 1.82-7.66) compared to nonfrail patients. Patients categorized as very frail by the RAI had an even higher risk of 3YMORT (OR 4.20, 95% CI 1.95-9.05), compared to nonfrail patients. CONCLUSIONS Patients with short life expectancy after vascular access creation may have high rates of AVF nonmaturation and longer time to maturation. Factors associated with high risk of mortality within 3 years of vascular access creation correlate well with factors included in the RAI frailty score. Patients who are frail or very frail may be appropriate candidates for AVG creation over AVF considering their high risk for short life expectancy.

Debunking the "Obesity Paradox": Obesity Is Associated With Adverse Outcomes in Emergency General Surgery. J Surg Res 2024; 301:95-102. [PMID: 38917579 DOI: 10.1016/j.jss.2024.05.040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 05/10/2024] [Accepted: 05/18/2024] [Indexed: 06/27/2024]
Abstract
INTRODUCTION Obesity is increasingly prevalent both nationwide and in the emergency general surgery (EGS) population. While previous studies have shown that obesity may be protective against mortality following EGS procedures, the association between body mass index (BMI) and postoperative outcomes, as well as intraoperative decision-making, remains understudied. METHODS The National Surgical Quality Improvement Program 2015-2019 database was used to identify all adult patients undergoing an open abdominal or abdominal wall procedure for EGS conditions. Our outcomes included 30-d postoperative mortality, composite 30-d morbidity, delayed fascial closure, reoperation, operative time, and hospital length of stay (LOS). Multivariable logistic regression models were used to explore the association between BMI and each outcome of interest while adjusting for patient demographics, comorbidities, laboratory tests, preoperative and intraoperative variables. RESULTS We identified 78,578 patients, of which 3121 (4%) were categorized as underweight, 23,661 (30.1%) as normal weight, 22,072 (28.1%) as overweight, 14,287 (18.2%) with class I obesity, 7370 (9.4%) with class II obesity, and 8067 (10.3%) with class III obesity. Class III obesity was identified as a risk factor for 30-d postoperative morbidity (adjusted odds ratio 1.14, 95% CI, 1.03-1.26, P < 0.01). An increase in obesity class was also associated with a stepwise increase in the risk of undergoing delayed fascial closure, experiencing a prolonged operative time, and having an extended LOS. CONCLUSIONS Obesity class was associated with an increase in delayed fascial closure, longer operative time, higher reoperation rates, and extended hospital LOS. Further studies are needed to explore how a patient's BMI impacts intraoperative factors, influences surgical decision-making, and contributes to hospital costs.

Abstract
Hepatocellular carcinoma (HCC) is an aggressive form of liver cancer that arises in a background of chronic hepatic injury. Metabolic syndrome-associated fatty liver disease (MAFLD) and its severe form, nonalcoholic steatohepatitis (NASH), are increasingly common mechanisms for new HCC cases. NASH-HCC patients are frequently obese and medically complex, posing challenges for clinical management. In this review, we discuss NASH-specific challenges and the associated implications, including benefits of minimally invasive operative approaches in obese patients; the value of y90 as a locoregional therapy; and the roles of weight loss and immunotherapy in disease management. The relevant literature was identified through queries of PubMed, Google Scholar, and clinicaltrials.gov. Provider understanding of clinical nuances specific to NASH-HCC can improve treatment strategy and patient outcomes.

[PMID: 39104935 PMCID: PMC11298150 DOI: 10.1177/22925503221128986] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 07/28/2022] [Accepted: 08/03/2022] [Indexed: 08/07/2024] Open
Abstract
Introduction: Reduction mammoplasty is becoming more commonly performed in the pediatric population yet the risk factors for complications have not been well-studied. The purpose of this study was to assess the relationship between preoperative patient characteristics and postoperative complications in a large population of pediatric patients undergoing reduction mammoplasty. Methods: Pediatric patients undergoing reduction mammoplasty were identified within the 2012 to 2019 National Surgical Quality Improvement Program database for cross-sectional study. The predictor variables were age, body mass index (BMI), diabetes, chronic steroid use, time under anesthesia, and operative time, and the primary outcome was a 30-day postoperative surgical site-related complication. Multivariate logistic regression was performed to identify a relationship between predictor variable and primary outcome. Results: A total of 1216 pediatric patients were identified with a mean age of 16.6 years and mean BMI of 30.8 kg/m2. The incidence of overall postoperative complications was 4.6%. Superficial surgical site infection (SSI) was the most common complication (29/1216; 2.4%). BMI was significantly associated with superficial SSI (odds ratio: 1.03, 95% confidence interval: 1.00-1.05, P = .02). Sixteen patients (1.32%) underwent a second operation, most commonly to address hematoma/seroma (7/16; 43.8%). Conclusion: In a large series of patients, pediatric reduction mammoplasty is a safe procedure with a low complication rate. BMI was significantly associated with the incidence of superficial SSIs with the most common cause for reoperation being a hematoma/seroma. This study can help guide the discussion between physicians and patients regarding potential risks associated with pediatric reduction mammoplasty.

Abstract
BACKGROUND Earlier studies have estimated the impact of increased body mass index (BMI) on healthcare costs. Various methods have been used to avoid potential biases and inconsistencies. Each of these methods measure different local effects and have different strengths and weaknesses. METHODS In the current study we estimate the impact of increased BMI on healthcare costs using nine common methods from the literature: multivariable regression analyses (ordinary least squares, generalized linear models, and two-part models), and instrumental variable models (using previously measured BMI, offspring BMI, and three different weighted genetic risk scores as instruments for BMI). We stratified by sex, investigated the implications of confounder adjustment, and modelled both linear and non-linear associations. RESULTS There was a positive effect of increased BMI in both males and females in each approach. The cost of elevated BMI was higher in models that, to a greater extent, account for endogenous relations. CONCLUSION The study provides solid evidence that there is an association between BMI and healthcare costs, and demonstrates the importance of triangulation.

Abstract
PURPOSE This study aimed to investigate and compare the surgical outcomes of younger and older patients after abdominal surgery and explore risk factors related to postoperative complications and in-hospital mortality in patients ≥65 years old. DESIGN A retrospective study on 540 adult patients who underwent abdominal surgery and stayed more than 48 hours in the hospital. METHODS The two groups of patients: younger than 65 years and ≥65 years old were compared related to postoperative complications, length of hospital stay, and mortality rates. The cohort of patients aged ≥65 years was selected to analyze risk factors for complications occurrence and in-hospital mortality. FINDINGS Patients ≥65 years old had poorer outcomes after abdominal surgery than younger patients. Pre-existence of comorbidities, American Society of Anesthesiologists physical status classification greater than two, emergency admission, and low preoperative serum albumin levels were risk factors for postoperative complications and mortality in elderly patients. Other risk factors for in-hospital mortality were the age ≥75 years, obesity, postoperative serum albumin level less than 30 g/L, presence of anemia before and after surgery, and occurrence of postoperative complications. Logistic regression revealed as independent risk factors for the postoperative complications the American Society of Anesthesiologists' physical status classification greater than two (odds ratio [OR]: 3.05, 95% confidence interval [CI]: 1.63-5.67, P = .0004) and preoperative serum albumin levels lower than 30 g/L (OR: 2.12, 95% CI: 1.08-4.17, P = .02), while for in-hospital postoperative mortality, independent risk factors were postoperative anemia (OR: 4.13; 95% CI: 1.22-13.97, P = .02) and obesity (OR: 7.65, 95% CI: 2.59-22.57, P = .0002). CONCLUSIONS Optimizing the preoperative conditions of older patients will improve their postoperative outcomes, especially for patients ≥75 years old, with obesity, comorbidities, anemia, severe nutritional risk, and emergency admission.

Abstract
BACKGROUND Although autologous reconstruction following breast cancer surgery is common, little is known about the association between preoperative body mass index (BMI) and short-term surgical outcomes. This study investigated the association between BMI and short-term surgical outcomes in autologous breast reconstruction using a nationwide Japanese inpatient database. METHODS We retrospectively identified female patients with breast cancer who underwent breast reconstruction using a pedicled flap or free flap from July 2010 to March 2020. Multivariable regression analyses and restricted cubic spline analyses were conducted to investigate the associations between BMI and short-term outcomes with adjustment for demographic and clinical backgrounds. RESULTS Of the 13,734 eligible patients, 7.1% and 22.2% had a BMI of < 18.5 kg/m2 and > 25 kg/m2, respectively. Compared with BMI of 18.5-21.9 kg/m2, overweight (25.0-29.9 kg/m2) and obese (≥ 30.0 kg/m2) were significantly associated with higher occurrences of takebacks (odds ratio, 1.74 [95% confidence interval, 1.28-2.38] and 2.89 [1.88-4.43], respectively) and overall complications (1.37 [1.20-1.57] and 1.77 [1.42-2.20], respectively). In the restricted cubic spline analyses, BMI showed J-shaped associations with takebacks, overall complications, local complications, and wound dehiscence. BMI also demonstrated linear associations with postoperative surgical site infection, duration of anesthesia, duration of drainage, length of stay, and hospitalization costs. CONCLUSION In autologous breast reconstruction following breast cancer surgery, a higher BMI was associated with takebacks, morbidity, a longer hospital stay, and higher total costs, whereas a lower BMI was associated with fewer surgical site infections, a shorter hospital stay, and lower total costs.

Abstract
BACKGROUND Literature addressing the risks associated with increasing body mass index (BMI) for patients undergoing free flap breast reconstruction is limited. Often, an arbitrary BMI cutoff (i.e., BMI of 30 kg/m2) is used to determine candidacy for a free flap without substantial backing evidence. This study utilized a national multi-institutional database to analyze outcomes of free flap breast reconstruction and stratified complications by BMI class. METHODS Using the 2010 to 2020 National Surgical Quality Improvement Program database, patients who underwent free flap breast reconstruction were identified. Patients were divided into six cohorts based on the World Health Organization BMI classes. Cohorts were compared by basic demographics and complications. A multivariate regression model was created to control for age, diabetes, bilateral reconstruction, American Society of Anesthesiologists class, and operative time. RESULTS Surgical complications increased with each BMI class, with the highest rates occurring in class I, II, and III obesity, respectively. In a multivariable regression model, the risk for any complication was significant for class II and III obesity (odds ratio [OR]: 1.23, p < 0.004; OR: 1.45, p < 0.001, respectively). Diabetes, bilateral reconstruction, and operative time were independently associated with an increased risk of any complication (OR: 1.44, 1.14, 1.14, respectively, p < 0.001). CONCLUSION This study suggests that the risks of postoperative complications following free flap breast reconstruction are highest for patients with a BMI greater than or equal to 35 kg/m2, having nearly 1.5 times higher likelihood of postoperative complications. Stratifying these risks by weight class can help guide preoperative counseling with patients and help physicians determine candidacy for free flap breast reconstruction.

Circulating cell-free DNA (cfDNA) has diverse applications in oncological, prenatal, toxicological, cardiovascular, and autoimmune diseases, diagnostics, and organ transplantation. In particular, mitochondrial cfDNA (mt-cfDNA) is associated with inflammation and linked to early vascular ageing (EVA) in end-stage kidney failure (ESKF), which could be a noninvasive marker for graft rejection and organ damage. Plasma samples from 44 ESKF patients, of whom half (n = 22) underwent either conservative therapy (non-HD) or hemodialysis (HD) before kidney transplantation (KT). These samples were analyzed at baseline and two years after KT. cfDNA was extracted from plasma and quantified using the fluorometric method. qPCR was used to quantify and differentiate the fractions of mt-cfDNA and nuclear cfDNA (nc-cfDNA). mt-cfDNA levels in KT patients decreased significantly from baseline to two years post-KT (p < 0.0268), while levels of total cfDNA and nc-cfDNA did not differ. Depending on therapy modality (HD vs. non-HD) before KT, total cfDNA levels were higher in HD patients at both baseline (p = 0.0133) and two years post-KT (p = 0.0421), while nc-cfDNA levels were higher in HD only at baseline (p = 0.0079). Males showed a nonsignificant trend of higher cfDNA levels. Patients with assessed vascular fibrosis (p = 0.0068), either alone or in combination with calcification plus fibrosis, showed reduced mt-cfDNA post-KT (p = 0.0195). Changes in mt-cfDNA levels suggests the impact of KT on the inflammatory state of ESKF, as evidenced via its correlation with high sensitivity C-reactive protein after KT. Further studies are warranted to assess if cfDNA could serve as a noninvasive method for monitoring the response to organ transplantation and even for amelioration of EVA status per se.

Abstract
BACKGROUND Global healthcare delivery is challenged by the aging population and the increase in obesity and type 2 diabetes. The extent to which such trends affect the cohort of patients the authors surgically operate on remains to be elucidated. Comprising of 8.7 million surgical patients, the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database can be analyzed to investigate the echo of general population dynamics and forecast future trends. MATERIAL AND METHODS The authors reviewed the ACS-NSQIP database (2008-2020) in its entirety, extracting patient age, BMI, and diabetes prevalence. Based on these data, the authors forecasted future trends up to 2030 using a drift model. RESULTS During the review period, median age increased by 3 years, and median BMI by 0.9 kg/m2. The proportion of patients with overweight, obesity class I, and class II rates increased. The prevalence of diabetes rose between 2008 (14.9%) and 2020 (15.3%). The authors forecast the median age in 2030 to reach 61.5 years and median BMI to climb to 29.8 kg/m2. Concerningly, in 2030, eight of ten surgical patients are projected to have a BMI above normal. Diabetes prevalence is projected to rise to 15.6% over the next decade. CONCLUSION General population trends echo in the field of surgery, with the surgical cohort aging at an alarmingly rapid rate and increasingly suffering from obesity and diabetes. These trends show no sign of abating without dedicated efforts and call for urgent measures and fundamental re-structuring for improved future surgical care.

Impact of Sarcopenic Obesity on Severe Postoperative Complications in Patients with Gastric Cancer Undergoing Gastrectomy. Dig Surg 2023; 40:143-152. [PMID: 37527628 DOI: 10.1159/000531797] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Accepted: 06/15/2023] [Indexed: 08/03/2023]
Abstract
INTRODUCTION Several studies have indicated that sarcopenia affects the short- and long-term outcomes of cancer patients, including those with gastric cancer. In recent years, sarcopenic obesity and its effects have been reported in cancer patients. This study aimed to evaluate the impact of sarcopenic obesity on postoperative complications in patients with gastric cancer undergoing gastrectomy. METHODS This single-center, retrospective study included 155 patients who underwent curative gastrectomy for gastric cancer from January 2015 to July 2021. Sarcopenia was defined by the psoas muscle index (<6.36 cm2/m2 in men and <3.92 cm2/m2 in women), which measures the iliopsoas muscle area at the lumbar L3 level using computed tomography. Obesity was defined by body mass index (≥25). Patients with both sarcopenia and obesity were defined as the sarcopenic obesity group and others as the non-sarcopenic obesity group. Severe postoperative complications were defined as Clavien-Dindo classification grade IIIa or higher. RESULTS Of the 155 patients, 26 (16.8%) had sarcopenic obesity. The incidence of severe postoperative complications was significantly higher in the sarcopenic obesity group (30.8% vs. 10.9%; p = 0.014). Multivariate analysis indicated that sarcopenic obesity was an independent risk factor for severe postoperative complications (odds ratio, 3.950; 95% confidence interval, 1.390-11.200; p = 0.010). CONCLUSION Sarcopenic obesity is an independent risk factor for severe postoperative complications.

Abstract
INTRODUCTION BMI has been shown to predict perioperative outcomes in patients undergoing surgery. Most studies assessing the role of body habitus in thyroid surgery have focused on open surgery, with few studies assessing patients undergoing robotic surgery. The present study evaluated the effects of BMI on surgical outcomes in patients undergoing bilateral axillo-breast approach (BABA) robotic thyroidectomy. MATERIALS AND METHODS This study included patients who underwent BABA robotic thyroidectomy between January 2013 and September 2021 at Seoul National University Bundang Hospital. Patients were categorized into six groups based on the WHO classification of overweight and obesity. Clinicopathological characteristics, postoperative complications, and surgical outcomes were evaluated. RESULTS A total of 1921 patients were included. Comparisons of the six BMI groups showed no statistically significant differences in postoperative stay, resection margin involvement, postoperative complications, and recurrence. Subgroup analysis showed that hypocalcemia rates differed among BMI groups in patients who underwent lobectomy, with underweight and class II obese patients being at the highest risk ( P =0.006). However, the actual number of complications was relatively small and similar among the groups. In patients who underwent total thyroidectomy and isthmectomy, BMI was not correlated with postoperative complications, including hypocalcemia, recurrent laryngeal nerve palsy, postoperative bleeding, and chyle leakage. CONCLUSION Body habitus was not significantly associated with operative time and postoperative complications in patients undergoing BABA robotic thyroidectomy, indicating that this approach is safe and feasible in obese patients.

Abstract
BACKGROUND The number of obese surgical patients continues to grow, and yet obesity's association with surgical outcomes is not totally clear. This study examined the association between obesity and surgical outcomes across a broad surgical population using a very large sample size. METHODS This was an analysis of the 2012 to 2018 American College of Surgeons National Surgical Quality Improvement database, including all patients from 9 surgical specialties (general, gynecology, neurosurgery, orthopedics, otolaryngology, plastics, thoracic, urology, and vascular). Preoperative characteristics and postoperative outcomes were compared by body mass index class (normal weight 18.5-24.9 kg/m2, overweight 25.0-29.9, obese class I 30.0-34.9, obese II 35.0-39.9, obese III ≥40). Adjusted odds ratios were computed for adverse outcomes by body mass index class. RESULTS A total of 5,572,019 patients were included; 44.6% were obese. Median operative times were marginally higher for obese patients (89 vs 83 minutes, P < .001). Compared to normal weight patients, overweight and obese patients in classes I, II, and III all had higher adjusted odds of developing infection, venous thromboembolism, and renal complications, but they did not exhibit elevated odds of other postoperative complications (mortality, overall morbidity, pulmonary, urinary tract infection, cardiac, bleeding, stroke, unplanned readmission, or discharge not home (except for class III patients). CONCLUSION Obesity was associated with increased odds of postoperative infection, venous thromboembolism, and renal but not the other American College of Surgeons National Surgical Quality Improvement complications. Obese patients need to be carefully managed for these complications.

Abstract
INTRODUCTION The Centers for Disease Control and Prevention (CDC) has deemed obesity a national epidemic and contributor to other leading causes of death including heart disease, stroke, and diabetes. Accordingly, the role of body mass index (BMI) and its impact on surgical outcomes has been a focus of persistent investigation. The purpose of this study was to quantify the effect of BMI on open abdominal aortic aneurysm repair (oAAA) outcomes in contemporary practice. METHODS All elective oAAAs in the VQI (2010-2021) were identified. End-points included 30-day death, in-hospital complications and 1-year mortality. Patients were stratified into four BMI cohorts (BMI<18.5, 18.5≤BMI<25, 25≤BMI<30, BMI≥30). Spline interpolation was used to explore a potential non-linear association between BMI and perioperative mortality. Mixed-effects Cox regression was used to assess the association between BMI and 1-year survival. RESULTS 9,479 patients underwent oAAA over the study interval (median age-70, 74%-male, BMI 27±6). Lower BMI patients(<18.5) compared to higher BMI(>30) patients were more likely to be women (53% vs. 32%;p<.0001), current smokers(65% vs. 50%;p<.0001), and have COPD(58% vs. 37%;p<.0001). In contrast, an increased BMI was associated with a greater prevalence of diabetes and CAD (DM-26% vs. 6%;p<.0001; CAD-27% vs. 20%;p=.01). There was no difference in cross-clamp position or visceral/renal bypass between groups, though low BMI patients necessitated more frequent infrainguinal bypass(5% vs. 2%;p=.0002). 30-day mortality and in-hospital complications were greater among low BMI patients(30-day mortality:12% vs. 4%;p<.0001;complications-47% vs. 37%;p<.0001). Interestingly, low BMI conferred a nearly 2-fold increase in observed pulmonary complications(18% vs. 11%;p<.0001). Surgical site infections were twice as common among the lowest and highest BMI groups(4% vs. 2%;p<.0001). 1-year mortality was greatest among low BMI patients(23% vs. 9%;p<.0001). Adjusted spline-fit analysis demonstrated increased mortality among patients with BMI<21 or >34(BMI<18.5-HR 2.1, 95%CI 1.6-2.8;p<.0001; BMI>34-HR 1.3, 95%CI 1.1-1.6;p=.009). CONCLUSION Both low (<18.5) and high (>34) BMI were associated with increased oAAA mortality in current practice. Despite the perception that obesity confers substantial surgical risk during oAAA, diminished BMI was associated with a 3-fold increase in 30-day and 1-year mortality. It appears that BMI extremes are distinct proxies for differential clinical phenotypes and should inform risk stratification for oAAA repair.

Do postoperative complications correlate to chronic pain following inguinal hernia repair? A prospective cohort study from the Swedish Hernia Register. Hernia 2023; 27:21-29. [PMID: 34894341 PMCID: PMC9931779 DOI: 10.1007/s10029-021-02545-y] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Accepted: 11/27/2021] [Indexed: 02/07/2023]
Abstract
PURPOSE To analyse if postoperative complications constitute a predictor for the risk of developing long-term groin pain. METHODS Population-based prospective cohort study of 30,659 patients operated for inguinal hernia 2015-2017 included in the Swedish Hernia Register. Registered post-operative complications were categorised into hematomas, surgical site infections, seromas, urinary tract complications, and acute post-operative pain. A questionnaire enquiring about groin pain was distributed to all patients 1 year after surgery. Multivariable logistic regression analysis was used to find any association between postoperative complications and reported level of pain 1 year after surgery. RESULTS The response rate was 64.5%. In total 19,773 eligible participants responded to the questionnaire, whereof 73.4% had undergone open anterior mesh repair and 26.6% had undergone endo-laparoscopic mesh repair. Registered postoperative complications were: 750 hematomas (2.3%), 516 surgical site infections (1.6%), 395 seromas (1.2%), 1216 urinary tract complications (3.7%), and 520 hernia repairs with acute post-operative pain (1.6%). Among patients who had undergone open anterior mesh repair, an association between persistent pain and hematomas (OR 2.03, CI 1.30-3.18), surgical site infections (OR 2.18, CI 1.27-3.73) and acute post-operative pain (OR 7.46, CI 4.02-13.87) was seen. Analysis of patients with endo-laparoscopic repair showed an association between persistent pain and acute post-operative pain (OR 9.35, CI 3.18-27.48). CONCLUSION Acute postoperative pain was a strong predictor for persistent pain following both open anterior and endo-laparoscopic hernia repair. Surgical site infection and hematoma were predictors for persistent pain following open anterior hernia repair, although the rate of reported postoperative complications was low.

Abstract
BACKGROUND There is controversy regarding the suitability of high body mass index (BMI) candidates accessing the transplant waitlist. PATIENTS AND METHODS Observational study on consecutive kidney transplant recipients undergoing surgery between January 2014 and March 2016 at our center. Patients were stratified according to BMI. Survival outcomes and graft function were analyzed to investigate the effect of donor's and recipient's demographic characteristics. RESULTS 396 kidney transplant recipients: 260 males, mean age 51.8 ± 15.9 years, followed up for a mean time of 5.86 ± 2.29 years. Mean BMI 26.2 ± 5.1. BMI class 1 (20 ≤ BMI ≤ 24.9) n=133, class 2 (25 ≤ BMI ≤ 29.9) n= 155, class 3 (30 ≤ BMI ≤34.9) n=53, class 4 (BMI ≥ 35) n=21, class V (BMI ≤ 19.9) n=34. Patient survival was not significantly different according to the recipient's BMI class (p=0.476); graft survival was affected (p=0.031), as well as graft function up to 2 years post-transplant and at 4 years follow up (p=0.016). At logistic regression the factors independently associated with graft loss were only donor's age (p=0.05) and BMI class of the recipient (p=0.002). CONCLUSIONS Obesity did not impact on patient's survival but affected graft function and graft loss.

Microsurgery 2023; 43:78-88. [PMID: 35611652 PMCID: PMC10084419 DOI: 10.1002/micr.30921] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Revised: 03/21/2022] [Accepted: 05/13/2022] [Indexed: 01/12/2023]
Abstract
BACKGROUND Microsurgical free tissue transfer (FTT) is a widely employed surgical modality utilized for reconstruction of a broad range of defects, including head and neck, extremity, and breast. Flap survival is reported to be 90%-95%. When FTT fails, salvage procedures aim at establishing reperfusion while limiting ischemia time-with salvage rates between 22% and 67%. There are limited data-driven predictors of successful salvage present in the literature. This systematic review aims to identify predictors of flap salvage. METHODS A systematic literature review was conducted per PRISMA guidelines. Articles included in the final analysis were limited to those investigating FTT salvage procedures and included factors impacting outcomes. Cohort and case series (>5 flaps) studies up until March 2021 were included. Chi-square tests and linear regression modeling was completed for analysis. RESULTS The patient-specific factors significantly associated with salvage included the absence of hypercoagulability (p < .00001) and no previous salvage attempts (p < .00001). Case-specific factors significantly associated with salvage included trunk/breast flaps (p < .00001), fasciocutaneous/osteocutaneous flaps (p = .006), venous compromise (p < .00001), and shorter time from index procedure to salvage attempt (R = .746). Radiation in the head and neck population was significantly associated with flap salvage failure. CONCLUSIONS Given the complexity and challenges surrounding free flap salvage procedures, the goal of this manuscript was to present data helping guide surgical decision-making. Based on our findings, patients without documented hypercoagulability, no previous salvage attempts, fasciocutaneous/osteocutaneous flaps, trunk/breast flaps, and a shorter time interval post-index operation are the best candidates for a salvage attempt.

Assessment of BMI and Venous Thromboembolism Rates in Patients on Standard Chemoprophylaxis Regimens After Undergoing Free Tissue Transfer to the Head and Neck. JAMA Otolaryngol Head Neck Surg 2022; 148:1051-1058. [PMID: 36201206 PMCID: PMC9539733 DOI: 10.1001/jamaoto.2022.2551] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Accepted: 08/20/2022] [Indexed: 12/13/2022]
Abstract
Importance Venous thromboembolism (VTE) is a severe complication after free tissue transfer to the head and neck (H&N). Enoxaparin 30 mg twice daily (BID) is a common regimen for chemoprophylaxis. However, differences in enoxaparin metabolism based on body weight may influence its efficacy and safety profile. Objective To assess the association between BMI and postoperative VTE and hematoma rates in patients treated with prophylactic enoxaparin 30 mg BID. Design, Setting, and Participants This was a retrospective review of a prospectively collected cohort from 2012 to 2022. Postoperative VTE, hematoma, and free flap pedicle thrombosis were recorded within 30 days of index surgery. The setting was a tertiary academic referral center. Participants included patients undergoing H&N reconstruction with free flaps that received fixed-dose subcutaneous enoxaparin 30 mg BID postoperatively. Statistical analysis was conducted from April to May 2022. Main Outcomes and Measures Outcomes include incidence of VTE, hematoma, and flap pedicle thrombosis events within 30 days of the surgery. Univariate and multivariable regression models were used to evaluate associations between BMI and other patient factors with these outcomes. Results Among the 765 patients included, 262 (34.24%) were female; mean (SD) age was 60.85 (12.64) years; and mean (SD) BMI was 26.36 (6.29). The rates of VTE and hematoma in the cohort were 3.92% (30 patients) and 5.09% (39 patients), respectively. After adjusting for patient factors, BMI was the only factor associated with VTE (OR, 1.07; 95% CI, 1.015-1.129). Obesity (BMI >30) was associated with increased odds of VTE (OR, 2.782; 95% CI, 1.197-6.564). Hematoma was not associated with BMI (OR, 0.988; 95% CI, 0.937-1.041). Caprini score of at least 9 was not associated with VTE (OR, 1.259; 95% CI, 0.428-3.701). Conclusions and Relevance This cohort study found that obesity was associated with an increased risk of VTE in patients after microvascular H&N reconstruction and while on standard postoperative chemoprophylaxis regimens. This association may suggest insufficient VTE prophylaxis in this group and a potential indication for weight-based dosing.

Int J Surg 2022; 107:106957. [PMID: 36252942 DOI: 10.1016/j.ijsu.2022.106957] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 10/05/2022] [Accepted: 10/10/2022] [Indexed: 12/07/2022]
Abstract
BACKGROUND Despite the worldwide increase of both obesity and the use of minimally invasive liver surgery (MILS), evidence regarding the safety and eventual benefits of MILS in obese patients is scarce. The aim of this study was therefore to compare the outcomes of non-obese and obese patients (BMI 18.5-29.9 and BMI≥30, respectively) undergoing MILS and OLS, and to assess trends in MILS use among obese patients. METHODS In this retrospective cohort study, patients operated at 20 hospitals in eight countries (2009-2019) were included and the characteristics and outcomes of non-obese and obese patients were compared. Thereafter, the outcomes of MILS and OLS were compared in both groups after propensity-score matching (PSM). Changes in the adoption of MILS during the study period were investigated. RESULTS Overall, 9963 patients were included (MILS: n = 4687; OLS: n = 5276). Compared to non-obese patients (n = 7986), obese patients(n = 1977) were more often comorbid, less often received preoperative chemotherapy or had a history of previous hepatectomy, had longer operation durations and more intraoperative blood loss (IOBL), paralleling significantly higher rates of wound- and respiratory-related complications. After PSM, MILS, compared to OLS, was associated, among both non-obese and obese patients, with less IOBL (200 ml vs 320 ml, 200 ml vs 400 ml, respectively), lower rates of transfusions (6.6% vs 12.8%, 4.7% vs 14.7%), complications (26.1% vs 35%, 24.9% vs 34%), bile leaks(4% vs 7%, 1.8% vs 4.9%), liver failure (0.7% vs 2.3%, 0.2% vs 2.1%), and a shorter length of stay(5 vs 7 and 4 vs 7 days). A cautious implementation of MILS over time in obese patients (42.1%-53%, p < .001) was paralleled by stable severe morbidity (p = .433) and mortality (p = .423) rates, despite an accompanying gradual increase in surgical complexity. CONCLUSIONS MILS is increasingly adopted and associated with perioperative benefits in both non-obese and obese patients.

Abstract
Objectives We aimed to explore whether body mass index (BMI) and albumin were associated with overall survival (OS) in individuals who underwent pancreaticoduodenectomy (PD) for cancer. Methods Three-hundred twenty-nine consecutive patients who underwent PD for cancer were enrolled from January 2020 to December 2020. All clinicopathological information was extracted based on medical records. The survival follow-ups were regularly performed and ended on June 30, 2021. The Kaplan-Meier survival analysis and univariate and multivariate Cox proportional-hazards models were used to assess the association of BMI and albumin with OS. Results Of the 329 patients, 186 (56.5%) were male, and median age at admission was 65.0 (56.0–71.0) years. There were 258 patients (78.4%) with BMI < 25.0 kg/m2 and 89 patients (27.05%) with albumin < 35.0 g/L respectively. In overall cohort, BMI < 25.0 kg/m2 was associated with OS (adjusted HR = 3.516, 95% CI = 1.076–11.492, P = 0.037). In contrast, albumin < 35.0 g/L did not affect OS. Subgroup analysis showed, in patients with pancreas lesion, BMI < 25.0 kg/m2 had a higher risk for OS compared to BMI ≥ 25.0 kg/m2 (adjusted HR = 3.209, 95% CI = 0.985–10.451, P = 0.048), while albumin < 35.0 g/L was not linked to OS. In patients with lesion in ampulla of Vater, duodenum, or common bile duct, there was no significant association of BMI and albumin with OS. Conclusions BMI, rather than serum albumin, was associated with OS in patients who underwent PD for cancer.

Abstract
Objectives The objective of this study is to elucidate the impact of income on short-term outcomes in a cerebellopontine angle (CPA) tumor resection population. Design This is a retrospective regression analysis. Setting This study was done at a single, multihospital, urban academic medical center. Participants Over 6 years (from June 7, 2013, to April 24, 2019), 277 consecutive CPA tumor cases were reviewed. Main Outcome Measures Outcomes studied included readmission, emergency department evaluation, unplanned return to surgery, return to surgery after index admission, and mortality. Univariate analysis was conducted among the entire population with significance set at a p -value <0.05. The population was divided into quartiles based on median household income and univariate analysis conducted between the lowest (quartile 1 [Q1]) and highest (quartile 4 [Q4]) socioeconomic quartiles, with significance set at a p -value <0.05. Stepwise regression was conducted to determine the correlations among study variables and to identify confounding factors. Results Regression analysis of 273 patients demonstrated decreased rates of unplanned reoperation ( p = 0.015) and reoperation after index admission ( p = 0.035) at 30 days with higher standardized income. Logistic regression between the lowest (Q1) and highest (Q4) socioeconomic quartiles demonstrated decreased unplanned reoperation ( p = 0.045) and decreasing but not significant reoperation after index admission ( p = 0.15) for Q4 patients. No significant difference was observed for other metrics of morbidity and mortality. Conclusion Higher socioeconomic status is associated with decreased risk of unplanned reoperation following CPA tumor resection.

Abstract
Background: The data about obesity on postoperative outcome after pancreatoduodenectomy (PD) are inconsistent, specifically in relation to gastric motility and delayed gastric emptying (DGE). Methods: Two hundred and eleven patients were included in the study and patients were retrospectively analyzed in respect to pre-existing obesity (obese patients having a body mass index (BMI) ≥ 30 kg/m2 vs. non-obese patients having a BMI < 30 kg/m2, n = 34, 16% vs. n = 177, 84%) in relation to demographic factors, comorbidities, intraoperative characteristics, mortality and postoperative complications with special emphasis on DGE. Results: Obese patients were more likely to develop clinically relevant pancreatic fistula grade B/C (p = 0.008) and intraabdominal abscess formations (p = 0.017). However, clinically relevant DGE grade B/C did not differ (p = 0.231) and, specifically, first day of solid food intake (p = 0.195), duration of intraoperative administered nasogastric tube (NGT) (p = 0.708), rate of re-insertion of NGT (0.123), total length of NGT (p = 0.471) or the need for parenteral nutrition (p = 0.815) were equally distributed. Moreover, mortality (p = 1.000) did not differ between the two groups. Conclusions: Obese patients do not show a higher mortality rate and are not at higher risk to develop DGE. We thus show that in our study, PD is feasible in the obese patient in regard to postoperative outcome with special emphasis on DGE.

Abstract
INTRODUCTION Recent studies have shown worse post-operative outcomes following several surgeries in underweight or obese patients. However, the association between body mass index (BMI) and short-term outcomes following thyroid cancer surgery remains unclear because of the small number of patients, deficits in background data known as risk factors (e.g. cancer stage, operative procedure, intraoperative device use and hospital volume) and categorisation of BMI. METHODS We identified patients who underwent thyroidectomy for differentiated thyroid cancer from July 2010 to March 2017 using a Japanese nationwide inpatient database. We used restricted cubic spline (RCS) analyses to investigate potential non-linear associations between BMI (without categorisation) and outcomes: post-operative complications (local and general), duration of anaesthesia, post-operative length of hospital stay and hospitalisation costs. The analyses were adjusted for demographic and clinical backgrounds including the above-stated factors. We also performed multivariable regression analyses for the outcomes with categorisation of BMI. RESULTS Among 59,671 eligible patients, the median BMI was 22.9 kg/m2 (interquartile range (IQR), 20.7-25.6 kg/m2). In total, 3860 patients (6.5%) had local complications and 787 patients (1.3%) had general complications. Although there were no significant associations with local complications, such as bleeding, recurrent laryngeal nerve paralysis and surgical site infection, the occurrence of general complications was significantly associated with higher BMI. BMI showed a linear association with the duration of anaesthesia and U-shaped associations with post-operative length of stay and hospitalisation costs. The lowest points of the U-shaped curves occurred at a BMI of approximately 24 kg/m2. The multivariate regression analyses showed consistent results with the RCS analyses. DISCUSSION/CONCLUSION Whereas RCS analyses revealed no significant associations between BMI and post-operative local complications, obesity was significantly associated with the occurrence of general complications. The linear association between BMI and duration of anaesthesia corresponds to previous studies. Although post-operative length of stay and total hospitalisation costs demonstrated U-shaped associations, the slight differences would not be clinically important. Even if surgeons must pay attention to general complications in obese patients undergoing thyroid cancer surgery as well as other surgeries, underweight and overweight patients can undergo thyroidectomy as safely as patients with normal BMI.

Abstract
BACKGROUND Several studies recommend that colonic hepatic flexure (CHF) should be mobilized preliminarily in minimally invasive pancreaticoduodenectomy (PD). However, there are little data to support that preferential mobilization of the CHF can positively affect the perioperative events of PD. We aimed to assess the effect of preferential mobilization of the CHF in PD. METHODS A retrospective cohort study of patients who underwent PD was performed between 2016 and 2019. Clinical characteristics, operative data, and postoperative surgical complications were recorded. RESULTS The study included 668 patients; 486 patients underwent open pancreaticoduodenectomy (OPD) and 182 patients underwent laparoscopic pancreaticoduodenectomy (LPD). Patients were divided into CHF-M (OPD, n=129; LPD, n=95) and conventional (OPD, n=357; LPD, n=87) groups according to preferential CHF mobilization. There were no differences between the groups regarding most demographics. Within patients who underwent OPD, decreased estimated blood loss (EBL) (251.2±146.4 vs. 307.3±173.5 mL, P<0.05) was observed in CHF-M group. Within patients who underwent LPD, operative time (328.7±66.3 vs. 406.5±85.5 min, P<0.001), EBL (166.8±96.4 vs. 271.8±130.7 mL, P<0.001), the incidence of clinically relevant pancreaticfistula (7.4% vs. 23.0%, P<0.05), and length of stay (12.3±5.1 vs. 16.0±7.4 d, P<0.05) were decreased in CHF-M group. Moreover, patients with high body mass index who underwent LPD showed more significant differences in operative time (336.0±67.7 vs. 431.9±79.1, P<0.001) and EBL (179.6±97.8 vs. 278.2±135.6, P<0.001) between groups. CONCLUSION We first demonstrated that preferential mobilization of the CHF can facilitate PD. The patients who underwent minimally invasive surgery and the patients with high body mass index may benefit more from this technique.

Ye P, Pang R, Li L, Li HR, Liu SL, Zhao L. Both Underweight and Obesity Are Associated With an Increased Risk of Coronavirus Disease 2019 (COVID-19) Severity. Front Nutr 2021; 8:649422. [PMID: 34692741 PMCID: PMC8531071 DOI: 10.3389/fnut.2021.649422] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Accepted: 09/02/2021] [Indexed: 12/23/2022] Open
Abstract
Introduction: As coronavirus Disease 2019 (COVID-19) has evolved into a global pandemic, increasing numbers of reports have linked obesity to more severe COVID-19 illness and death. However, almost all the studies focused on an increased risk of mortality or intensive care unit (ICU) admission among hospitalized obese patients with COVID-19. Is obesity also associated with the incidence of acute lung injury (ALI) in the patients with COVID-19? How about underweight patients? The answer is lacking. Therefore, our following research will answer the above two questions. Methods: We collected and analyzed epidemiologic, demographic, clinical, and laboratory data from 193 confirmed cases of COVID-19 at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology in Wuhan, China, between January 1, 2020, and March 13, 2020. They were followed up until April 15, 2020. Underweight was defined by body mass index (BMI) lower than 18.5 kg/m2, normal weight by 18.5-23.9 kg/m2, overweight by 24.0-27.9 kg/m2, and obesity as ≥28 kg/m2. Results: Among these patients, 5.70% were underweight, 58.03% were normal weight, 27.98% were overweight, and 8.29% were obese. Underweight patients were more likely to have a headache (P = 0.029). Obese patients were more likely than other groups to experience a decline in lymphocyte counts (P = 0.038), an increase in C-reactive protein (CRP; P = 0.023), bilateral multiple mottling, and ground glass opacity in the lungs (P = 0.007). Besides, the proportion of patients receiving human immunoglobulin + systematic corticosteroids treatment is the highest among the obese group compared with other BMI groups. After adjusting for potential confounders, underweight patients had a 6.483-fold higher (P = 0.012), and obese patients showed a 5.965-fold higher odds for developing ALI than normal-weight patients (P = 0.022). In addition, underweight patients were 3.255 times more likely than normal-weight patients to develop secondary infections (P = 0.041). Conclusions: Our study showed that both underweight and obese patients with COVID-19 tend to develop ALI compared with normal-weight patients. Underweight patients were more likely to develop a secondary infection than other patients.

[PMID: 34059346 DOI: 10.1016/j.surg.2021.04.028] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Revised: 03/29/2021] [Accepted: 04/21/2021] [Indexed: 12/29/2022]
Abstract
BACKGROUND The impact of obesity on postoperative outcomes after pancreatoduodenectomy remains insufficiently studied. METHODS All pancreatoduodenectomy patients were abstracted from the 2014 to 2018 American College of Surgeons National Surgical Quality Improvement Program data sets and were stratified into the following 3 body mass index categories: non-obese (body mass index 18.5-29.9), class 1/2 obesity (body mass index 30-39.9), and class 3 severe obesity (body mass index ≥ 40). Analyses tested associations between patient factors and four 30-day postoperative outcomes: mortality, composite morbidity, delayed gastric emptying, and postoperative pancreatic fistula. Multivariable logistic regression models tested independent associations between patient factors and these 4 outcome measures. RESULTS A total of 16,823 patients were included in the study: 12,234 (72.7%) non-obese, 4,030 (24%) obese, and 559 (3.3%) with severe obesity. Bivariable analyses demonstrated significant associations between obesity, severe obesity, and greater proportions of numerous preoperative comorbidities as well as a greater likelihood of postoperative complications, including postoperative pancreatic fistula, delayed gastric emptying, composite morbidity, and mortality (all P ≤ .001). After adjusting for significant covariates, obesity was independently associated with postoperative pancreatic fistula (odds ratio 1.49, 95% confidence interval: 1.33-1.67, P < .001), delayed gastric emptying (odds ratio 1.16, 95% confidence interval: 1.05-1.28, P = .004), composite morbidity (odds ratio 1.28, 95% confidence interval: 1.18-1.38, P < .001), and mortality (odds ratio 1.79, 95% confidence interval: 1.36-2.36, P < .001). CONCLUSION Obesity and severe obesity are significantly associated with worse short-term outcomes after pancreatoduodenectomy. Preoperative considerations, such as weight management strategies during individualized treatment planning, could improve outcomes in this population.

Abstract
BACKGROUND Preoperative nutritional assessment of cancer patients is important to reduce postoperative complications. Several studies have reported the Geriatric Nutritional Risk Index (GNRI) to be useful in assessing underlying diseases and long-term outcomes of hospitalized patients. The present study aimed to evaluate the impact of preoperative GNRI on short- and long-term outcomes in elderly gastric cancer patients who underwent laparoscopic gastrectomy. METHODS We retrospectively reviewed consecutive patients aged ≥ 65 years who underwent laparoscopy-assisted gastrectomy and had R0 resection for histologically confirmed gastric adenocarcinoma. The cutoff value for preoperative GNRI was determined to be 85.7 based on the incidence of postoperative complications. Patients were categorized into two groups: low GNRI group and normal GNRI group. RESULTS Univariate analyses of the 303 patients revealed that the incidence of postoperative complications was significantly associated with the American Society of Anesthesiologists Physical Status classification (ASA-PS), C-reactive protein (CRP), GNRI (p < 0.001), and operative procedure. Multivariate analyses revealed that preoperative GNRI (odds ratio [OR] 2.716; 95% confidence interval [CI] 1.166-6.328; p = 0.021) and operative procedure (OR 2.459; 95% CI 1.378-4.390; p = 0.002) were independently associated with the incidence of postoperative complications. Univariate analyses showed that overall survival (OS) was significantly associated with ASA-PS, tumor size, tumor differentiation, pathological tumor node metastasis (TNM) stage, carcinoembryonic antigen (CEA), CRP, GNRI, and postoperative complications. Multivariate analysis demonstrated that ASA-PS (hazard ratio [HR], 3.755; 95% CI 2.141-6.585; p < 0.001), tumor differentiation (HR 1.898; 95% CI 1.191-3.025; p = 0.007), CEA (HR 1.645; 95% CI 1.024-2.643; p = 0.040), and GNRI (HR 2.093; 95% CI 1.105-3.963; p = 0.023) independently predicted OS. CONCLUSION GNRI is an important predictor of postoperative complications and overall survival in elderly gastric cancer patients. It is a reliable and cost-effective prognostic indicator that should be routinely evaluated.

Abstract
PURPOSE It is well documented that the interaction between many social factors can affect clinical outcomes. However, the independent effects of economics on outcomes following surgery are not well understood. The goal of this study is to investigate the role socioeconomic status has on postoperative outcomes in a cerebellopontine angle (CPA) tumor resection population. MATERIALS AND METHODS Over 6 years (07 June 2013 to 24 April 2019), 277 consecutive CPA tumor cases were reviewed at a single, multihospital academic medical center. Patient characteristics obtained included median household income, Charlson Comorbidity Index (CCI), race, BMI, tobacco use, amongst 23 others. Outcomes studied included readmission, ED evaluation, unplanned return to surgery (during and after index admission), return to surgery after index admission, and mortality within 90 days, in addition to reoperation and mortality throughout the entire follow-up period. Univariate analysis was conducted amongst the entire population with significance set at a p value <0.05. The population was divided into quartiles based on median household income and univariate analysis conducted between the lowest (Q1) and highest (Q4) socioeconomic quartiles, with significance set at a p value <0.05. Stepwise regression was conducted to determine the correlations amongst study variables and identify confounding factors. RESULTS Regression analysis of 273 patients did not find household income to be associated with any of the long-term outcomes assessed. Similarly, a Q1 vs Q4 comparison did not yield significantly different odds of outcomes assessed. CONCLUSION Although not statistically significant, the odds ratios suggest socioeconomic status may have a clinically significant effect on postsurgical outcomes. Further studies in larger, matched populations are necessary to validate these findings.

Abstract
The National Clinical Database (NCD) of Japan was established in 2010 with the board certification system. A joint committee of 16 gastroenterological surgery database-affiliated organizations has been nurturing this nationwide database and utilizing its data for various analyses. Stepwise board certification systems have been validated by the NCD and are used to improve the surgical outcomes of patients. The use of risk calculators based on risk models can be particularly helpful for establishing appropriate and less invasive surgical treatments for individual patients. Data obtained from the NCD reflect current developments in the surgical approaches used in hospitals, which have progressed from open surgery to endoscopic and robot-assisted procedures. An investigation of the data acquired by the NCD could answer some relevant clinical questions and lead to better surgical management of patients. Furthermore, excellent surgical outcomes can be achieved through international comparisons of the national databases worldwide. This review examines what we have learned from the NCD of gastroenterological surgery and discusses what future developments we can expect.

Outcomes of Urinary Diversion for Late Adverse Effects of Gynecologic Radiotherapy. Urology 2020; 144:214-219.

Abstract
OBJECTIVE To describe the risks of urinary diversion performed to address adverse effects of gynecologic radiation, with the hypothesis that high grade complications would be more common in sarcopenic women and in those undergoing continent diversion (vs noncontinent) or concomitant cystectomy (vs bladder-sparing diversion). METHODS A retrospective review was performed of patient records of women who underwent urinary diversion for urinary adverse effects of gynecologic radiotherapy during the period of 2008-2018 from 3 tertiary centers. Skeletal muscle index was calculated to assess for sarcopenia based on preoperative computed tomography scans. Outcomes include high-grade postoperative complications within 90 days of surgery, 30-day readmission rate, and long-term (>90 days) outcomes. RESULTS Among 34 women who met the inclusion criteria, the majority were white/Caucasian (73.5%). Twenty-six of 34 (76.5%) underwent noncontinent diversion. Seventy nine percent (27/34) (79.4%) of women experienced complications within 90 days; 9 of 34 (26.5%) experienced high-grade (Clavien grade ≥3) complications. Thirty-two percent (11/34) were readmitted within 30 days. Rates of high-grade complications were not significantly impacted by diversion type (P = .49), concurrent cystectomy (P = .70), or sarcopenia (P = 1.0). CONCLUSIONS Urinary diversion for late adverse effects of gynecologic radiotherapy is associated with high peri-operative risk, even in skilled hands. In this series, neither sarcopenia, nor continent diversion, nor cystectomy were associated with increased complications. Patients and surgeons should consider risks and benefits when deciding to proceed with urinary diversion, however further study is needed to elucidate significant preoperative markers which may predispose patients to significant complications.

Abstract
BACKGROUND Recent studies have shown better postoperative outcomes in mildly obese patients, a phenomenon called the obesity paradox. In the field of breast cancer surgery, however, previous studies have only shown an association between obesity and worse postoperative outcomes using multivariable analysis; the obesity paradox has not been investigated in patients undergoing breast cancer surgery. PATIENTS AND METHODS We identified patients who underwent mastectomy for stage 0 to III breast cancer from July 2010 to March 2017 using a Japanese nationwide inpatient database. We used restricted cubic spline analyses to investigate potential nonlinear associations between body mass index (BMI) and outcomes (postoperative complications, 30-day readmission, duration of anesthesia, length of hospital stay, and hospitalization costs). We also performed multivariable regression analyses for the outcomes. RESULTS Among 239,108 eligible patients, 25.6% had a BMI of > 25.0 kg/m2. BMI showed U-shaped associations with postoperative complications, length of stay, and hospitalization costs, and a linear association with duration of anesthesia. The proportion of postoperative complications was lowest at a BMI of around 22.0 kg/m2, while the length of stay was shortest and total costs were lowest at a BMI of around 20.0 kg/m2. Compared to a BMI of 22.0 kg/m2, a BMI of > 30.0 kg/m2 was significantly associated with greater postoperative complications, 30-day readmission, duration of anesthesia, length of stay, and hospitalization costs. CONCLUSION Restricted cubic spline analyses displayed U-shaped associations between BMI and in-hospital complications, length of stay, and hospitalization costs, but none of the associations showed the obesity paradox.

Abstract
BACKGROUND Obesity is generally considered to be associated with worse surgical outcome and impaired oncological prognosis. The impact of pre-therapeutic body mass index (BMI) in patients with oesophagogastric cancer on the surgical outcome is controversially discussed. METHODS We retrospectively examined 730 patients who had undergone curative treatment for oesophagogastric cancer at the Medical Center of the University of Freiburg (1996-2015). Patients were divided in groups according to pre-therapeutic BMI (underweight (UW): <18.5 kg/m2 ; normal weight (NW): 18.5-25 kg/m2 ; overweight (OW): 25-30 kg/m2 ; and obese (OB): >30 kg/m2 ). RESULTS Median BMI was 24.7 kg/m2 . Forty-two patients were UW, 337 NW, 263 OW and 84 OB. No significant differences between the groups (UW/NW/OW/OB) in operating time, hospital stay, perioperative complication rate and in-hospital mortality were found. Pre-therapeutic BMI was significantly associated with 5-year survival (UW: 22%, NW: 37%, OW: 51%, OB: 50%, P < 0.001). Multivariate analysis identified UW/NW (BMI <25 kg/m2 ) as an independent risk factor for poor survival (relative risk 1.38, P = 0.001) among high American Society of Anesthesiologists score, old age, positive resection margin and high cancer stage according to the Union Internationale Contre le Cancer (UICC). CONCLUSION In oesophagogastric cancer, OW and OB patients can be treated surgically without impaired perioperative outcome and expect improved long-term survival compared to patients with a BMI <25 kg/m2 .

Obes Rev 2019; 20:1159-1183. [PMID: 30945439 DOI: 10.1111/obr.12855] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2019] [Revised: 03/01/2019] [Accepted: 03/03/2019] [Indexed: 11/29/2022]
Abstract
This study systemically reviewed evidence linking adiposity to readmission and all-cause mortality in post-coronary artery bypass grafting (CABG) patients. Keyword/reference search was performed in PubMed, Web of Science, CINAHL, and Cochrane Library for articles published before June, 2018. Eligibility criteria included study designs: experimental/observational studies; subjects: adult patients undergoing CABG; and outcomes: hospital/clinic readmissions, and short-term (≤30 days) and mid-to-long-term (>30 days) all-cause mortality. Seventy-two studies were identified. Meta-analysis showed that the odds of post-CABG readmission among patients with overweight was 30% lower than their normal-weight counterparts and the odds of mid-to-long-term post-CABG mortality among patients with overweight were 20% lower than their normal-weight counterparts. In contrast, no difference in post-CABG readmission rate was found between patients with obesity and their nonobese counterparts; no difference in short-term or in-hospital post-CABG mortality rate was found between patients with overweight or obesity and their normal-weight counterparts; and no difference in mid-to-long-term post-CABG mortality rate was found between patients with obesity and their normal-weight counterparts. In conclusion, patients with overweight but not obesity had a lower readmission and mid-to-long-term mortality rate following CABG relative to their normal-weight counterparts. Preoperative weight loss may not be advised to patients with overweight undergoing CABG.

ACTA ACUST UNITED AC 2019; 55:medicina55060218. [PMID: 31141961 PMCID: PMC6631593 DOI: 10.3390/medicina55060218] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2019] [Accepted: 05/23/2019] [Indexed: 01/12/2023]
Abstract
Background and objective: The most commonly performed bariatric procedures include laparoscopic sleeve gastrectomy (LSG), laparoscopic Roux-en-Y gastric bypass (LRYGB), and one anastomosis gastric bypass-mini gastric bypass (OAGB-MGB). A study comparing the degree of difficulty among those procedures could serve as a guide for decision making in bariatric surgery and further improve training programs for general surgery trainees. The aim of this study was to compare the subjective level of technical difficulty of LSG, LRYGB, and OAGB-MGB as perceived by surgeons and surgical residents. Materials and Methods: An anonymous internet-based survey was designed to evaluate the subjective opinions of surgeons and surgical residents in training in Poland. It covered baseline characteristics of the participants, difficulty of LSG, OAGB-MGB, LRYGB and particular stages of each operation assessed on a 1-5 scale. Results: Overall, 70 surgeons and residents participated in our survey. The mean difficulty degree of LSG was 2.34 ± 0.89. The reinforcing staple line with sutures was considered most difficult stage of this operation (3.17 ± 1.19). The LRYGB operation had an average difficulty level of 3.87 ± 1.04. Creation of the gastrojejunostomy was considered the most difficult stage of LRYGB with a mean difficulty level (3.68 ± 1.16). Responders to our survey assessed the mean degree of difficulty of OAGB-MGB as 2.34 ± 0.97. According to participating surgeons, creating the gastrojejunostomy is the most difficult phase of this operation (3.68 ± 1.16). Conclusion: The LSG is perceived by surgeons as a relatively easy operation. The LRYGB was considered to be the most technically challenging procedure in our survey. Operative stages, which require intra-abdominal suturing with laparoscopic instruments, seem to be the most difficult phases of each operation.

Abstract
PURPOSE Narrow thoracic inlet might be associated with increased incidence of cervical anastomotic leakage (AL) after esophagectomy with retrosternal reconstruction. We retrospectively evaluated the relationship of the length from the suprasternal notch to the trachea (LST) and AL using computed tomography. METHODS In this retrospective study including 121 patients with esophageal cancer who underwent subtotal esophagectomy with retrosternal reconstruction between 2008 and 2016, clinicopathological characteristics, including the LST, surgical procedures, and perioperative outcomes, were compared between the AL and non-AL groups. RESULTS AL occurred in 19 of the 121 patients (15.7%). There were no associations between AL development and age, sex, body mass index, tumor location, TNM stage, histological type, surgical approach, or type of the anastomotic procedure. Surgery duration was longer in the AL group than in the non-AL group (p = 0.004). Other surgical factors such as intra-operative blood loss and anastomotic technique were not associated with AL. LST was significantly shorter in the AL group than in the non-AL group (p < 0.001). Multivariate analysis revealed that LST was a significant predictor of AL (p < 0.001). CONCLUSION LST is a simple and useful predictor of AL after esophagectomy with retrosternal reconstruction.

Abstract
AIM To evaluate the efficacy of single-incision laparoscopic surgery for totally extraperitoneal repair in overweight or obese patients. MATERIALS AND METHODS For outcome analyses, patients were subdivided by body mass index (BMI) as normal-weight (18.5≤BMI<25 kg/m), overweight (25≤BMI<30 kg/m) or obese (≥30 kg/m) and compared. RESULTS In total, 201 patients were divided into a normal-weight group (n=152) and an overweight/obese group (n=49). Median operative time for unilateral hernia was 72 minutes in the normal-weight group and 95 minutes in the overweight/obese group (P<0.05). No significant differences in operative time for bilateral hernia, bleeding volume, peritoneal injury, conversion to a different procedure, postoperative hospital stay, follow-up duration, complications, or recurrence were identified. CONCLUSIONS Single-incision laparoscopic surgery for totally extraperitoneal repair, which offers good cosmetic outcomes, seems feasible and safe for overweight or obese patients, although the operation takes longer.

Abstract
Aims and Objectives: Malnutrition is common in children with congenital heart disease and may contribute to adverse outcomes. This study evaluates the impact of pre-operative nutritional status on outcomes after congenital heart surgery. Methods: We conducted a retrospective cohort study enrolling children under 10 years old who underwent congenital heart surgery at a tertiary children's hospital from 2012 to 2016. Patients who had patent ductus arteriosus ligation only, genetic syndromes, or global developmental delay were excluded. Outcome measures included 30-day mortality, intensive care unit (ICU) length of stay (LOS), hospital LOS, duration of mechanical ventilation, and number of inotropes used post-operatively. We performed univariate/multivariable logistic regression analysis, adjusting for age, cyanotic cardiac lesion, co-morbidity, and Risk Adjustment for Congenital Heart Surgery (RACHS-1) score. Results: Three hundred two children of median age 16.2 [interquartile range (IQR) 3.1, 51.4)] months were included. The most common cardiac lesions were ventricular septal defect (27.8%), atrial septal defect (17.9%), and Tetralogy of Fallot (16.6%). Median weight-for-age z-score (WAZ) was -1.46 (IQR -2.29, -0.61), height-for-age z-score (HAZ) was -0.94 (IQR -2.10, -0.10), and body mass index (BMI)-for-age z-score (BAZ) was -1.11 (IQR -2.19, -0.30). In multivariable analysis, there was an increased risk of 30-day mortality for WAZ ≤-2 vs. WAZ >-2 [adjusted odds ratio (aOR): 4.01, 95% CI: 1.22, 13.13; p = 0.022]. For HAZ ≤-2 vs. HAZ > -2, there was increased risk of hospital LOS ≥ 7 days (aOR: 2.08, 95% CI: 1.12, 3.89; p = 0.021), mechanical ventilation ≥48 h (aOR: 2.63, 95% CI: 1.32, 5.24; p = 0.006) and of requiring ≥3 inotropes post-operatively (aOR: 3.00, 95% CI: 1.37, 6.59; p = 0.006). Conclusion: In children undergoing congenital heart surgery, WAZ ≤ -2 is associated with higher 30-day mortality, while HAZ ≤ -2 is associated with longer durations of hospital LOS and mechanical ventilation, and increased risk of use of 3 or more inotropes post-operatively. Future studies are necessary to develop safe and efficacious peri-operative nutritional interventions, particularly in patients with WAZ and HAZ ≤ -2.

Abstract
PURPOSE To comparatively examine in-hospital mortality among different underweight body mass index (BMI) categories in pancreatic cancer patients after pancreatectomy in Japan. METHODS We conducted a large-scale multi-center retrospective cohort study of adult patients with pancreatic cancer who underwent pancreatectomy between April 1, 2010 and March 31, 2016. Patients were classified according to BMI as follows: normal BMI (18.50-24.99 kg/m2), mild thinness (17.00-18.49 kg/m2), moderate thinness (16.00-16.99 kg/m2), and severe thinness (< 16.00 kg/m2). A multivariable logistic regression analysis was performed with in-hospital mortality as the dependent variable and BMI groups as the main independent variable of interest. RESULTS We analyzed 6173 patients from 332 hospitals. The results showed that the severe thinness group had a longer postoperative hospital stay (34.4 ± 25.6 days) and higher incidence of postoperative pneumonia (5.5%) than the other groups. The generalized estimating equations accounted for patient demographics, surgical procedure, anesthetic technique, activities of daily living score, and Charlson comorbidity index as covariates. Relative to the normal BMI group, the odds ratios for in-hospital mortality were 0.57 (95% confidence interval: 0.26-1.24; P = 0.16) in the mild thinness group, 1.49 (0.64-3.48; P = 0.36) in the moderate thinness group, and 2.54 (1.05-6.08; P = 0.04) in the severe thinness group. CONCLUSION Severe thinness was significantly associated with a higher risk of mortality, and extremely low BMI should be considered a risk factor in pancreatectomy patients.

Abstract
In recent years, both the actual number of overweight/obese individuals and their proportion of the population have steadily been rising worldwide and obesity-related diseases have become major health concerns. In addition, as obesity is associated with an increased incidence of gastroenterological cancer, the number of obese patients has also been increasing in the field of gastroenterological surgery. While the influence of obesity on gastroenterological surgery has been widely studied, very few reports have focused on individual organs or surgical procedures, using a cross-sectional study design. In the present review, we aimed to summarize the impacts of obesity on surgeries for the esophagus, stomach, colorectum, liver and pancreas. In general, obesity prolongs operative time. As to short-term postoperative outcomes, obesity might be a risk for certain complications, depending on the procedure carried out. In contrast, it is possible that obesity doesn't adversely impact long-term surgical outcomes. The influences of obesity on surgery are made even more complex by various categories of operative outcomes, surgical procedures, and differences in obesity among races. Therefore, it is important to appropriately evaluate perioperative risk factors, including obesity.

Abstract
PURPOSE A study was conducted to clarify the actual status of nutrition management after gastric cancer surgery in Japan and obtain basic data for optimizing perioperative nutrition management. METHODS A questionnaire was sent to 354 hospitals with at least 50 cases of gastric cancer surgery per year. Questions included the perioperative nutrition management and length of hospital stay for patients who underwent gastric cancer surgery within three months of the survey. RESULTS Responses were obtained from 242 hospitals (68%; 20,858 patients). Nutrition management was consistent between laparotomy and laparoscopic surgery for 84% of respondents. The number of postoperative days was the most commonly chosen index for starting oral feeding. The most commonly chosen index for hospital dischargeability was diet composition/amount consumed in 182 hospitals (44%), followed by laboratory data stabilization in 106 hospitals (26%), and the number of postoperative days in 87 hospitals (21%). A positive correlation was found between the mean length of postoperative hospital stay and starting oral feeding (r = 0.23 for distal gastrectomy; r = 0.34 for total gastrectomy). The length of hospital stay tended to be shorter with an earlier start of oral feeding (p < 0.01). CONCLUSION Early postoperative oral feeding may be a factor in reducing the length of hospital stay after gastric cancer surgery.

Abstract
Background Current literature frequently indicates that experienced laparoscopic surgeons can safely perform single-incision laparoscopic cholecystectomy, but there have been few reports evaluating the feasibility and safety of performing single-incision laparoscopic cholecystectomy for obese patients. Therefore, a large single-center database was retrospectively reviewed to evaluate the feasibility and safety of single-incision laparoscopic cholecystectomy for obese patients by comparing the outcomes of normal-weight and obese patients undergoing single-incision laparoscopic cholecystectomy. Methods A retrospective analysis of 608 patients undergoing SILC between May 2009 and May 2015 at Osaka Police Hospital was performed, and the outcomes of obese [body mass index (BMI) ≥ 30 kg/m2] and normal-weight patients (18.5 ≤ BMI < 25 kg/m2) were compared. Results Thirty-eight obese patients (mean BMI 32.5 kg/m2) were compared to 362 normal-weight patients (mean BMI 22.0 kg/m2). The American Society of Anesthesiologists (ASA) scores of the obese patients were significantly higher than those of normal-weight patients. The mean operative times in the normal-weight and the obese groups were 110 min vs. 127 min, respectively (p < 0.05). There were no significant differences in the bleeding volume and the conversion rate to a different operative procedure. Perioperative complications were seen in 6% (23/362) of the patients in the normal-weight group and 8% (3/38) of the patients in the obese group (p = 0.7). The mean postoperative hospital stay was 4.5 days for the normal-weight group and 4.4 days for the obese group (p = 0.8). Conclusions Single-incision laparoscopic cholecystectomy, which offers good cosmetic outcomes, seems feasible and safe in obese patients.
Single-incision laparoscopic cholecystectomy offers good cosmetic outcomes. Single-incision laparoscopic cholecystectomy seems feasible and safe in obese patients.

Abstract
Oral fat sensitivity (OFS, the ability to detect fat) may be related to overeating-induced obesity. However, it is largely unknown whether OFS affects taste preference and eating habits. Therefore, we aimed to evaluate (1) the association between body mass index (BMI) and OFS and (2) the relationship of OFS with four types of taste preference (sweet, sour, salty, and bitter) and eating habits using serial concentrations of oleic acid (OA) homogenized in non-fat milk and a self-reported questionnaire. Participants were 25 healthy Japanese individuals (mean age: 27.0 ± 5.6 years), among whom the OA detection threshold was significantly associated with BMI. Participants were divided into two subgroups based on oral sensitivity to 2.8 mM OA: hypersensitive (able to detect 2.8 mM OA, n = 16) and hyposensitive (unable to detect 2.8 mM OA, n = 9). The degree of sweet taste preference of the hypersensitive group was significantly higher than that of the hyposensitive group. Furthermore, there was significantly higher degree of preference for high-fat sweet foods than low-fat sweet foods in the hypersensitive group. There was also a significant inverse correlation between the OA detection threshold and the degree of both spare eating and postprandial satiety. Thus, OFS is associated not only with BMI, but also with the preference for high-fat sweet foods and eating habits. The present study provides novel insights that measuring OFS may be useful for assessing the risk of obesity associated with overeating in countries, including Japan, where BMI is increasing in the population.

Abstract
OBJECTIVE Obesity is associated with increased risk of diabetes, hypertension and cardiovascular mortality. Several studies have reported increased length of hospital stay and complications; however, there are also reports of obesity having a protective effect on health, a phenomenon coined the 'obesity paradox'. We aimed to investigate the impact of overweight and obesity on complications and mortality in hospitalized patients with hyperglycemia and diabetes. RESEARCH DESIGN AND METHODS This retrospective analysis was conducted on 29 623 patients admitted to two academic hospitals in Atlanta, Georgia, between January 2012 and December 2013. Patients were subdivided by body mass index into underweight (body mass index <18.5 kg/m(2)), normal weight (18.5-24.9 kg/m(2)), overweight (25-29.9 kg/m(2)) and obese (>30 kg/m(2)). Hyperglycemia was defined as a blood glucose >10 mmol/L during hospitalization. Hospital complications included a composite of pneumonia, acute myocardial infarction, respiratory failure, acute kidney injury, bacteremia and death. RESULTS A total of 4.2% were underweight, 29.6% had normal weight, 30.2% were overweight, and 36% were obese. 27.2% of patients had diabetes and 72.8% did not have diabetes (of which 75% had hyperglycemia and 25% had normoglycemia during hospitalization). A J-shaped curve with higher rates of complications was observed in underweight patients in all glycemic groups; however, there was no significant difference in the rate of complications among normal weight, overweight, or obese patients, with and without diabetes or hyperglycemia. CONCLUSIONS Underweight is an independent predictor for hospital complications. In contrast, increasing body mass index was not associated with higher morbidity or mortality, regardless of glycemic status. There was no evidence of an obesity paradox among inpatients with diabetes and hyperglycemia.
