The rising clinical importance of assessing frailty is driven by its predictive capability for postoperative outcomes. This study assesses the effectiveness of RAI-rev (Revised Risk Analysis Index) in predicting adverse outcomes in lower extremity (LE) flap reconstruction.

 Analyzing NSQIP (National Surgical Quality Improvement Program) data from 2015 to 2020, we compared demographics, perioperative factors, and 30-day outcomes in all locoregional and free-flap cases. Frailty scores, calculated using RAI-rev, were categorized with <15 as nonfrail and >35 as the most frail. Adjusted odds ratios (aORs) for specific complications were calculated using nonfrail as the reference group. Frailty scores in locoregional flaps were compared with those in free flaps.

 We identified 270 locoregional and 107 free-flap cases. Higher RAI-rev scores in locoregional flaps correlated with increased complications, such as deep surgical site infection (1% nonfrail vs. 20% RAI 31-35), stroke (0% nonfrail vs. 17% most frail), and mortality (0% nonfrail vs. 17% most frail). Locoregional flap cases with RAI-rev scores in the most frail group had a significantly elevated aOR for stroke (51.0, 95% confidence interval [CI]: 1.8-1402.5, p = 0.02), mortality (43.1, 95% CI: 1.6-1167.6, p = 0.03), and any complication (6.8, 95% CI: 1.2-37.4, p = 0.03). In free-flap cases, higher RAI-rev scores were associated with increased complications, with only sepsis showing a statistically significant difference (6% nonfrail vs. 100% most frail; aOR: 42.3, CI: 1.45-1245.3, p = 0.03). Free-flap cases had a significantly lower RAI-rev score compared with locoregional flap cases (14.91 vs. 17.64, p = 0.01).

 Elevated RAI-rev scores (>35) correlated with more complications in locoregional flaps, while free-flap reconstruction patients had generally low RAI-rev scores. This suggests that free flaps are less commonly recommended for presumed higher risk patients. The study demonstrates that RAI-rev may be able to serve as a risk calculator in LE reconstruction, aiding in the assessment of candidates for limb salvage versus amputation.

The 5-item modified Frailty Index (mFI-5) is a clinical tool to predict adverse outcomes in surgical patients by assessing five comorbidities: diabetes, hypertension, congestive heart failure, chronic obstructive pulmonary disease, and dependent functional status. It helps to evaluate postoperative complication risks, recovery time, and overall survival, particularly in frail patients undergoing oncological and gynecological surgeries.

This retrospective cohort study analyzed American College of Surgeons, National Surgical Quality Improvement Program data from adult female patients undergoing mastectomy procedures without reconstruction between 2017 and 2022. Patients were selected based on Current-Procedural-Terminology codes, excluding incomplete or non-breast-related cases. Preoperative, perioperative, and 30-day postoperative data were analyzed using logistic and linear regression models, with the mFI-5 cutoff set at 2.

Between 2017 and 2022, 860 patients underwent mastectomies at Yale Healthcare Network; 19% (n = 163) had mFI score ≥2. High-risk patients (mFI ≥2) were significantly older (66.32 ± 10.83 years) and had a higher body mass index (33.69 ± 7.73, both p < 0.001). Surgical complications occurred in 11.98% of patients, with a higher rate in the high-risk group (22.7% vs. 9.5%, p < 0.001). Adjusted multivariate logistic regression showed an increased risk of complications in frail patients (aOR 2.66; [1.60-4.43], p < 0.001). Although slight reductions in hospital stay and surgery duration were observed for high-risk patients, these differences were not significant. Sensitivity analysis confirmed higher odds of complications, including acute kidney failure (odds ratio [OR] 9.01) and pneumonia (OR 4.10).

The mFI-5 is a robust tool for predicting surgical complications in patients undergoing mastectomy, particularly those with multiple comorbidities.

Early warning system (EWS) scores are implemented on surgical wards to identify patients at high risk of postoperative clinical deterioration, but its predictive value in older patients is unclear. This study assessed the prognostic value of EWS scores to predict severe postoperative complications in older patients compared to younger patients.

This study utilized data from the TRACE study. EWS scores were routinely measured on postoperative days one (POD1) and three (POD3). The cohort was divided by age: < 70 years and ≥ 70 years. Performance measures of EWS scores on POD1 and POD3 were assessed to predict severe postoperative complications. Missed event rates (proportion of events not detected by the EWS threshold) and nonevent rates (proportion of EWS values above the threshold without an adverse event) were calculated.

Among 4866 patients, 39.3% were ≥ 70 years old. Severe complications occurred in 6.1% of older compared to 5.8% of younger patients (P = 0.658). EWS scores on POD1 and POD3 did not differ between age groups. For severe complications, EWS showed moderate discrimination in both older (POD1: C-statistic 0.65 (95%CI 0.59-0.70); POD3: 0.63 (95%CI 0.57-0.69)) and younger patients (POD1: 0.68 (95%CI 0.65-0.72); POD3: 0.65 (95%CI 0.61-0.70)). Overall, calibration was good. For EWS score ≥ 3, the missed event rate was at least 69% and nonevent rate 75%.

Predicted performance of the EWS score was moderate among older and younger patients. A limitation of the EWS score is the high rate of missed events and nonevents.

Clostridioides difficile (formerly known as Clostridium difficile) is a significant cause of healthcare-associated infection with symptoms ranging from diarrhoea and abdominal pain to pseudomembranous colitis and toxic megacolon. Severe disease can pose a significant morbidity and mortality risk and is to be considered a medical emergency. The emergence of a new C. difficile ribotype with an estimated mortality rate of 20% (ribotype 995) has prompted a re-review of the evidence and guidelines around managing severe C. difficile infections (CDI). International guidance on the management of CDI varies regarding first-line antibiotic choice. Metronidazole is no longer favoured as first line due to concerns around resistance, and vancomycin and fidaxomicin are now recommended as first line options. Antibiotic therapy should be used in conjunction with good supportive measures and early consideration of surgical management. Faecal microbiota transplant can be utilized in recurrent CDI and may be useful in severe disease. Severe CDI is a significant ongoing threat to public health, and further research into effective management is essential to ensure the best possible outcomes for patients.

Postoperative frailty is an important determinant of postoperative recovery and survival outcomes. Predicting the onset of postoperative frailty is significant importance for the rehabilitation of the elderly people after surgery. Our study aims to develop and evaluate a predictive model for postoperative frailty on the 30th day in elderly patients.

Data from seven Guangzhou hospitals were collected, encompassing 2,290 patients for analysis. This study constructed the model using LASSO regression and stepwise regression, and the optimal predictive model was selected based on comparison. Model performance was assessed through calibration curves, the area under the ROC curve (AUC), and decision curve analysis (DCA).

The final model included the following variables: American Society of Anesthesiologists (ASA) grade, intraoperative blood loss, economic income, caregiver status, sedentary behavior, cognitive function, Activities of Daily Living (ADL), postoperative hemoglobin (Hb) level, and postoperative ICU admission. The model demonstrated good discrimination, with an area under the curve (AUC) of 0.7431 (95% CI = 0.7073-0.7788) in the training set and 0.7285 (95% CI = 0.6671-0.7624) in the validation set.

According to general demographic information, lifestyle habits, and surgery-related factors, a predictive model for postoperative frailty in the elderly was constructed, which has good predictive power. This model can identify high-risk populations for postoperative frailty and provides a reference for the early detection and intervention of frailty in the elderly in clinical practice.

This study was registered on May 17, 2023, at the Chinese Clinical Trial Registry (registration number: ChiCTR2300071535).

Frailty is a spectrum describing a demographic more likely to experience adverse events such as falls, disability, and hospital admission which can be quantified by the modified frailty index (mFI). Several studies have associated increased mFI score with higher rates of hospital readmission and length of stay (LOS). This study tests the predictive value of a frailty questionnaire based on the mFI on LOS and 30-day readmission rates.

This retrospective chart review included all patients aged 60 or older who underwent multi-level LIF by 13 surgeons at a single institution. Patients were classified as frail (mFI > 1) or non-frail (mFI ≤ 1). Statistical analysis was performed on Microsoft Excel and included t-testing, linear correlations, and analysis of variance.

A total of 213 patients were included in the study with an average frailty score of 2.26. Frail patients had significantly increased LOS (P < 0.001) with no significant difference between vertebral levels (P = 0.27). Linear correlations between frailty score and LOS or readmission rate were positive in all cases with variable strength dependent on number of levels fused. Conclusions The frailty questionnaire is an effective method of predicting LOS and risk of 30-day post-operative readmission in elderly patients undergoing multi-level LIF. The questionnaire format will allow for increased ease of obtaining frailty scores, so that improved pre-operative decision-making can be made among clinicians and patients alike. Future studies may be performed to identify the best method of interpreting frailty scores and may be expanded to a multi-institutional level.

Postoperative delirium (POD) is a common, transient postoperative cognitive dysfunction in elderly patients. The relationship between POD and intraoperative hypotension remains unclear. This study aims to determine if intraoperative hypotension predicts POD in elderly male patients undergoing laryngectomy.

This study included male patients over 65 years old who underwent laryngectomy between April 2018 and January 2022. The Confusion Assessment Method (CAM) was used to diagnose delirium. Intraoperative hypotension was defined as a Mean Arterial Pressure (MAP) during surgery that was less than 30% of the preoperative level for at least 30 minutes. The relationship between intraoperative hypotension and POD incidence was adjusted for patient demographics and surgery-related factors.

Out of 428 male patients, 77 (18.0%) developed POD, and 166 (38.8%) experienced intraoperative hypotension. Surgery duration ≥ 300 minutes (OR = 1.873, 95% CI 1.041-3.241, p = 0.036), intraoperative hypotension (OR = 1.739, 95% CI 1.039-2.912, p = 0.035), and schooling (OR = 2.655, 95% CI 1.338-5.268) were independent risk factors for POD. The association between intraoperative hypotension and POD was significantly influenced by surgery duration (p for interaction = 0.008), with a stronger association in prolonged surgeries (adjusted OR = 4.902; 95% CI 1.816-13.230).

Intraoperative hypotension and low education level are associated with an increased risk of POD in elderly male patients undergoing laryngectomy, especially with prolonged surgery duration.

Owing to the particularities of their physical characteristics, older patients undergoing surgery under general anesthesia experience great surgical traumas. Thus, exploring more refined and individualized nursing approaches is an urgent need to mitigate the negative effects of surgery on such patients.

To analyze the influence of preoperative comprehensive education on anxiety, depression, pain, and sleep in older patients who underwent surgery under general anesthesia.

In total, 163 older adults who underwent surgery under general anesthesia between June 2022 and November 2023 were selected, 77 of them received routine nursing care (control group), and 86 received preoperative comprehensive education (research group). Subsequently, comparative analyses were performed from the following perspectives: Surgical indicators (operation time, time to complete regain of consciousness, and temperature immediately after the procedure and upon recovery from anesthesia) before and after nursing care; negative emotions [self-rating anxiety scale (SAS)/self-rating depression scale (SDS)]; pain severity [visual analog scale (VAS)]; sleep quality [Pittsburgh sleep quality index (PSQI)]; incidence of sleep disturbances (difficulties in falling asleep for the first time, falling asleep again after waking up frequently at night, falling asleep again after waking up early, and falling asleep all night); and incidence of adverse events (airway obstruction, catheter detachment, aspiration, and asphyxia).

The research group had significantly lower operation time and time to complete regain of consciousness than the control group after nursing care and markedly better recovery of postoperative body temperature and body temperature at awakening. In addition, more notable decreases in SAS, SDS, VAS, and PSQI scores were observed in the research group than in the control group. Furthermore, the incidence rate of sleep disturbance (8.14% vs 29.87%) and adverse events (4.65% vs 19.48%) were lower in the research group than in the control group.

Preoperative comprehensive education in older patients who underwent surgery under general anesthesia can improve postoperative indicators, effectively reduce the occurrence of anxiety and depression, alleviate postoperative pain, and improve sleep quality.

As the population ages, the prevalence of age-related frailty increases sharply, which increases the risk of poor health status of older adults, such as disability, falls, hospitalization, and death. Across the globe, frailty is moving toward the forefront of health and medical research. Currently, frailty is believed to be preventable and reversible, so the early identification of frailty is critical. However, there are neither precise biomarkers of frailty nor definitive laboratory tests and corresponding clinical testing techniques and equipment in clinical practice. As a result, the clinical identification of frailty is mainly achieved through the widely used frailty scale, which is an objective, simple, time-saving, effective, economical, and feasible measurement tool. In this narrative review, we summarized and analyzed the various existing frailty scales from different perspectives of screening and evaluation, aiming to provide a reference for clinical researchers and practitioners to judge and manage frail older people accurately.

Although cholecystectomy is a common surgery, it carries higher risks of postoperative complications and mortality for older adults. Age alone is not a reliable predictor of postoperative outcomes, whereas frailty may provide a more accurate assessment of a patient's health and functional status. Frailty, characterized by physical deterioration and reduced resilience, has been shown to predict mortality, prolonged recovery, and morbidity after various surgeries, including cholecystectomy. Thus, incorporating frailty evaluations into preoperative assessments can improve patient outcomes by individualizing treatment strategies. This systematic review and meta-analysis aims to evaluate how well frailty predicts postoperative outcomes following cholecystectomy.

In accordance with PRISMA guidelines, we searched PubMed, Embase, and Web of Science on August 14th, 2024, without restrictions on publication year or language. The quality of the studies was assessed using the Newcastle-Ottawa scale, and meta-analysis was conducted using odds ratios with 95% confidence intervals as the effect size, employing a random-effects model.

Nine cohort studies comprising a total of 128,421 participants were included. The pooled results showed significantly higher odds of short-term mortality (OR: 5.54, 95% CI: 1.65-18.60, p = 0.006), postoperative morbidity (OR: 2.65, 95% CI: 1.51-4.64, p = 0.001), major morbidity (OR: 3.61, 95% CI: 1.52-8.59), and respiratory failure (OR: 3.85, 95% CI: 1.08-13.79) among frail patients. Additionally, frail patients had longer hospital stays (mean difference: 2.98 days, 95% CI: 1.91-4.04) and significantly higher odds of postoperative infection and sepsis. However, no association was evident with reoperation rates.

This study highlights the value of utilizing frailty assessment tools in preoperative settings for predicting outcomes after cholecystectomy. These tools could improve decision-making in both emergency and elective situations, aiding in the choice between surgical and medical management, as well as between open and laparoscopic procedures tailored to each patient.

Introduction Sarcopaenia has been examined as a predictor of frailty in surgical patients and may predict mortality. The hypothesis of this study is that sarcopaenia is associated with an increased risk of death following an episode of acute lower gastrointestinal bleeding (ALGB). Methods This study included patients admitted with ALGB between January 2017 and June 2022, who underwent cross-sectional imaging (CSI). CSI was accessed via imaging platforms, and the total psoas area (TPA) was calculated at the third lumbar vertebra (L3) by a radiology resident (post-Fellowship of the Royal College of Radiologists (FRCR)) and validated by a consultant radiologist. Clinical, mortality, and demographic data were obtained from the Northern Ireland Electronic Care Record (NIECR). Psoas muscle index (PMI) was calculated using TPA, standardising for height in mm2/m2. Sarcopaenia was defined as PMI <545 mm2/m2 for males and <385 mm2/m2 for females. Results A total of 103 patients were included. Of these, 32 patients were defined as sarcopaenic (male, n = 20; female, n = 12). There was a statistically significant increase in mortality in the sarcopaenic group (Chi square (1, N = 103 = 7.582, p = 0.005888), odds ratio (OR) of 3.34, 95% confidence interval (CI) of 1.41-7.91). The Kaplan-Meier curve showed a significant decrease in survival probability in combined male and female groups (p < 0.001). There was a statistically significant association between sarcopaenic patients and length of hospital stay (LOHS) compared with non-sarcopaenic patients (p < 0.001). Conclusions Sarcopaenia as a predictor of frailty is an important risk factor for all-cause mortality in ALGB. CSI provides an opportunity to identify as well as investigate the aetiology of ALGB. Although radiation risk may limit its use, it should be considered when available.

The modified 5-item frailty index (mFI-5) is a comorbidity-based risk stratification tool previously validated in patients undergoing several surgical procedures. This study investigates the association between mFI-5 score and cricopharyngeal myotomy (CM) complications.

Retrospective database review.

US hospitals.

The National Surgical Quality Improvement Program database was queried for patients who underwent CM between 2005 and 2018. mFI-5 score was determined by assigning 1 point for comorbidities including: diabetes mellitus, hypertension, congestive heart failure, chronic obstructive pulmonary disease, and dependent health status. Univariate and multivariable analyses were conducted to determine associations between mFI-5 score and postoperative complications.

A total of 1075 patients undergoing CMs were queried and stratified into the following groups: mFI = 0 (n = 412 [38.3%]), mFI = 1 (n = 452 [42.0%]), and mFI ≥ 2 (n = 211 [19.6%]). Univariate analysis showed association between higher mFI-5 scores with older age, higher American Society of Anesthesiologists Classification class, obesity, smoking, dyspnea, and systemic sepsis. Higher mFI-5 was associated with a greater proportion of cumulative surgical complications, cumulative medical complications, pneumonia, myocardial infarction, cumulative morbidity, readmissions, unplanned readmissions, and reoperations. Multivariable analyses found associations between greater mFI-5 score and cumulative morbidity (odds ratio [OR] = 1.95, confidence interval [CI]: 1.29-2.96, P = .002), any surgical complication (OR = 1.80, CI: 1.15-2.79, P = .010), readmission (OR = 1.81, CI: 1.01-3.26, P = .047), and reoperations (OR = 1.96, CI: 1.04-3.68, P = .037).

Evaluating mFI-5 can help assess the risk of postoperative complications for patients undergoing CM.

Level 4.

Owing to the gradual aging of today's population, an increase in the prevalence of frailty syndrome has been noticed. This complex state of health, characterized by decreased resilience and tolerance with concurrent increased vulnerability to stressors and adverse health-related factors, has drawn researchers' attention in recent years. Rectal cancer, which constitutes ~30% of all colorectal cancers, is a disease noticeably related to the elderly. In its locally advanced form, it is conventionally treated with trimodal therapy-neoadjuvant chemoradiotherapy followed by total mesorectal excision and adjuvant chemotherapy. Despite its good clinical outcomes and improvement in rectal cancer local control, as evidenced by clinical trials, it remains unclear if all frail patients benefit from that approach since it may be associated with adverse side effects that cannot be handled by them. As old patients, and frail ones even more noticeably, are poorly represented in the clinical trials describing outcomes of the standard treatment, this article aims to review the current knowledge on the trimodal therapy of rectal cancer with an emphasis on novel approaches to rectal cancer that can be implemented for frail patients.

Many tools have been used to assess frailty in the perioperative setting. However, no single scale has been shown to be the most effective in predicting postoperative complications. We evaluated the relationship between several frailty scales and the occurrence of complications following different non-cardiac surgeries.

This systematic review was registered in PROSPERO (CRD42023473401). The search strategy included PubMed, Google Scholar, and Embase, covering manuscripts published from January 2000 to July 2023. We included prospective and retrospective studies that evaluated frailty using specific scales and tracked patients postoperatively. Studies on cardiac, neurosurgical, and thoracic surgery were excluded because of the impact of underlying diseases on patients' functional status. Narrative reviews, conference abstracts, and articles lacking a comprehensive definition of frailty were excluded.

Of the 2204 articles identified, 145 were included in the review: 7 on non-cardiac surgery, 36 on general and digestive surgery, 19 on urology, 22 on vascular surgery, 36 on spinal surgery, and 25 on orthopedic/trauma surgery. The reviewed manuscripts confirmed that various frailty scales had been used to predict postoperative complications, mortality, and hospital stay across these surgical disciplines.

Despite differences among surgical populations, preoperative frailty assessment consistently predicts postoperative outcomes in non-cardiac surgeries.

Patients with cirrhosis awaiting liver transplantation (LT) are often frail, and malnourished. The period of time on the waitlist provides an opportunity to improve their physical fitness. Prehabilitation appears to improve the physical fitness of patients before major surgery. Little is known about prehabilitation in patients with cirrhosis. The aim of this feasibility study will be to investigate the feasibility, safety, and effectiveness of a multimodal prehabilitation programme in this patient population.

This is an open-label single-arm feasibility trial recruiting 25 consecutive adult patients with cirrhosis active on the LT waiting list of the McGill University Health Centre (MUHC). Individuals will be excluded based on criteria developed for the safe exercise training in patients with cirrhosis. Enrolled individuals will participate in a multimodal prehabilitation programme conducted at the PeriOperative Programme complex of the MUHC. It includes exercise training with a certified kinesiologist (aerobic and resistance training), nutritional optimisation with a registered dietician and psychological support with a nurse specialist. The exercise training programme is divided into an induction phase with three sessions per week for 4 weeks followed by a maintenance phase with one session every other week for 20 weeks. Aerobic training will be individualised based on result from cardiopulmonary exercise testing (CPET) and will include a high-intensity interval training on a cycle ergometer. Feasibility, adherence and acceptability of the intervention will be assessed. Adverse events will be reviewed before each visit. Changes in exercise capacity (6-minute walk test, CPET, liver frailty index), nutritional status and health-related quality of life will be assessed during the study. Post-transplantation outcomes will be recorded.

The research ethics board of the MUHC has approved this study (2021-7646). Our findings will be submitted for presentation at national and international conferences, and for peer-reviewed publication.

NCT05237583.

The appropriateness of laparoscopic gastrectomy (LG) for super-geriatric patients with locally advanced gastric cancer (LAGC) is inconclusive, and the prognostic factors are also yet to be elucidated. Herein, we aimed to investigate the surgical and oncological outcomes of LG versus open gastrectomy (OG) for geriatric patients with LAGC who have outlived the average lifespan of the Chinese population (≥ 78 years).

This is a monocentric, retrospective, comparative study. A 1:1 propensity score matching (PSM) was performed to minimize selection bias and ensure well-balanced characteristics. The primary endpoint of interest was 3-year overall survival, while secondary endpoints included procedure-related variables, postoperative recovery indices, and complications. Univariate and multivariate Cox proportional hazards regression analyses were performed to identify unfavorable prognostic factors.

Of 196 eligible individuals, 107 underwent LG and 89 underwent OG, with a median age (interquartile range [IQR]) of 82 [79, 84] years. PSM yielded 61 matched pairs, with comparable demographic and tumor characteristics. The LG group had a significantly lower overall complication rate than the OG group (31.1% vs. 49.2%, P = 0.042), as well as shorter duration of postoperative hospital stay [12 (11, 13) vs. 13 (12, 15.5) d, P < 0. 001], less intraoperative blood loss [95 (75, 150) vs. 230 (195, 290) mL, P < 0.001], but a longer operative time [228 (210, 255.5) vs. 196 (180, 219.5) min, P < 0.001]. The times to first aerofluxus, defecation, liquid diet, and half-liquid diet were comparable. Kaplan-Meier analyses revealed no significant difference in 3-year overall survival between the groups, either in the entire cohort or in subgroups with different TNM staging. Moreover, Age-adjusted Charlson Comorbidity Index scores of > 6 [hazard ratio (HR) 4.003; P = 0.021] and pathologic TNM stage III (HR 3.816, P = 0.023) were independent unfavorable prognostic factors for long-term survival.

LG performed by experienced surgeons offers the benefits of comparable or better surgical and oncological safety profiles than OG for super-geriatric patients with LAGC.

The growing number of elderly patients in hospitals is a challenge for healthcare systems. The main objective is to measure the postoperative change in the cognitive status at hospital discharge and one year after discharge in elderly patients undergoing planned or deferrable surgery.

We planned a prospective longitudinal study, single-center study: secondary care level hospital, enrolment from September 2018 to May 2019. We enroll elderly patients, aged above life expectancy in Italy, who underwent planned or deferrable surgery (men over 80.5 years old, women over 85.0 years old). In six months, we enrolled 76 eligible patients. We collected the scores of the clinical impairment scales Charlson Index, Barthel Index, and Six-Item Cognitive Impairment Test (6CIT). The primary endpoint was the postoperative worsening of the cognitive status at one-year follow-up. Secondary endpoints aimed to describe postoperative disabilities and complications, to investigate possible risk factors for cognitive worsening, and to measure the role of anesthesia in cognitive changes.

We recorded an increased rate of pathological 6CIT values during the hospitalization period, rising from 39.47% to 55.26% (McNemar test, P=0.007), and this rate was still increased at 55.56% (P=0.021) one year after discharge. Anesthesia did not show any significant harmful effect on cognitive status. The preoperative hemoglobin value seems to be a risk factor for cognitive status and one-year mortality.

Elderly patients had a significantly worse 6CIT value after planned surgery, which may derive in part from age and in part from hospitalization. It is difficult to determine if general anesthesia alone has no harmful effects on cognitive performance in patients at discharge and one year later. Further data are necessary.

Frailty metrics estimate a patient's ability to tolerate physiologic stress and there are limited frailty data in patients undergoing expanded endonasal approaches (EEA) for suprasellar pathologies. Elevated frailty metrics have been associated with increased perioperative complications in patients undergoing craniotomies. We sought to examine this potential relationship in EEA.

Retrospective cohort study.

Two tertiary academic skull base centers.

Cases of patients undergoing EEA for suprasellar pathologies were reviewed. Demographic, treatment, survival, and postoperative outcomes data were recorded. Frailty was calculated using validated indexes, including the American Society of Anesthesiologists (ASA) classification, the modified 5-item frailty index (mFI-5), and the Charlson comorbidity index (CCI). Primary outcomes included 30-day medical and surgical complications.

A total of 88 patients were included, with 59 (67%) female patients and a mean age of 54 ± 15 years. The most common pathologies included 53 meningiomas (60.2%) and 21 craniopharyngiomas (23.9%). Most patients were ASA class 3 (54.5%) with mean mFI-5 0.82 ± 1.01 and CCI 4.18 ± 2.42. There was no association between increased frailty and 30-day medical or surgical outcomes (including postoperative cerebrospinal fluid leak), prolonged length of hospital stay, or mortality (all P > .05). Higher mFI-5 was associated with an increased risk for 30-day readmission (odds ratio: 2.35, 95% confidence Interval: 1.10-5.64, P = .04).

Despite the patient population being notably frail, we only identified an increased risk for 30-day readmission and observed no links with deteriorating surgical, medical, or mortality outcomes. This implies that conventional frailty metrics may not effectively align with EEA outcomes.

Scientific evidence of nonsurgical site-related complications in mandibular fracture patients is limited.

The purpose was to measure the frequency of nonsurgical site complications in patients with mandible fractures, describe the types of complications, and identify the risk factors associated with these complications.

A retrospective cohort study was conducted at the Helsinki University hospital between 2018 and 2021. Patients undergoing surgery with open reduction and internal fixation of mandibular fracture(s) were evaluated. Patients under 16 years of age were excluded.

Primary predictor variable was age. Patient-related predictor variables were sex, long-term disease(s), smoking, and alcohol and/or drug abuse. Injury and fracture-related variables were injury mechanism, type and site of facture, combined craniofacial fracture(s), and associated injury(s).

The primary outcome variable was nonsurgical site-related postoperative complication. The secondary outcome variable was type of complication.

Not applicable.

The main outcome variable was cross tabulated for pairwise comparisons with predictor variables. Multivariate logistic regression was performed for statistically significant (P < .05) variables.

The data included 314 patients (age range: 16 to 89 years; mean age: 38 years old; median age: 33 years old); most (78.3%) were men. Nonsurgical site-related postoperative complications occurred in 6.7% of patients. The most common complication type was pulmonary complication (36.0%), followed by urinary complication (20.0%) and general infection (16.0%). Nonsurgical site-related postoperative complications were most likely to occur in patients who were elderly (adjusted odds ratio [aOR] 5.55; 95% CI 1.92 to 16.21; P = .002), had combined craniofacial fractures (aOR 2.92; 95% CI 1.06 to 8.03; P = .038), and abused alcohol or drugs (aOR 4.51; 95% CI 1.70 to 11.96; P = .003). Pulmonary complications occurred more often in elderly patients, whereas urinary complications were more common in younger patients.

The types of nonsurgical site complications in mandibular fracture patients increase and vary according to the patient's age. Awareness of possible complications related to different age groups helps anticipate and identify these in clinical work, and to consider the overall treatment of the patient beyond the fracture.

Frailty is an important risk factor for adverse events (AEs), especially in elderly patients. Therefore, assessing frailty before therapy is recommended. In head and neck squamous cell carcinoma (HNSCC) patients, frailty is prognostic for severe postoperative complications and declining quality of life (QoL) after HNSCC treatment. Thus, assessment of frailty may help to identify individuals at risk for AE caused by oncologic therapy. We investigated the relationship between frailty and symptom burden to better understand their interaction and impact on HNSCC patients. In this prospectively designed cross-sectional study, the presence of frailty and symptom burden was assessed by using the Geriatric 8 (G8) and Minimal Documentation System (MIDOS2) questionnaires. A total of 59 consecutively accrued patients with a first diagnosis of HNSCC before therapy were evaluated. Patients were considered frail at a total G8 score ≤ 14. The MIDOS2 symptom burden score was considered pathological with a total score ≥ 4 or any severe symptom (=3). Statistical correlations were analyzed using Spearman and Pearson correlation. Receiver operator characteristic (ROC) curves were used to analyze the potential of predicting frailty and MIDOS2. p-values < 0.05 were considered significant. A total of 41 patients (69.5%) were considered frail, and 27 patients (45.8%) had increased symptom burden. "Tiredness" was the most common (overall rate 57.8%) and "Pain" was the most often stated "severe" symptom (5 patients, 8.5%). G8 and MIDOS2 correlated significantly (ρ = -0.487, p < 0.001; r = -0.423, p < 0.001). Frailty can be predicted by MIDOS2 symptom score (AUC = 0.808, 95% CI 0.698-0.917, p < 0.001). Vice versa, the G8 score can predict pathological symptom burden according to MIDOS2 (AUC = 0.750, 95% CI 0.622-0.878, p < 0.001). Conclusions: The strong link between frailty and increased symptom burden assessed by G8 or MIDOS2 indicates a coherence of both risk factors in HNSCC patients. Considering at least one of both scores might improve the identification of individuals at risk and achieve higher QoL and reduced complication rates by decision making for appropriate therapy regimens.

The FRAIL scale for evaluating frailty consists of five items: fatigue, resistance, aerobic, illness, and loss of weight. However, it is difficult to obtain a specific weight loss value. Since the Timed Up and Go Test (TUGT) is simple, accurate, and easy to perform, we replaced weight loss with the TUGT in the FRAIL scale, with the remaining four items unchanged, and named it the FRAIT scale. The aim of this study was to determine the value of the FRAIT scale in predicting the peri-operative outcome of hepatectomy.

This model development study was conducted between January 2017 and December 2021. The reliability, validity and area under the curve (AUC) of the FRAIL/FRAIT scales were calculated. The frailty status of patients aged ≥ 75 years who underwent hepatectomy was measured using the FRAIL/FRAIT scales. Logistic regression was used to compare the relationship between FRAIL/FRAIT scores/grades and perioperative outcomes.

The AUCs for predicting operation duration, intraoperative bleeding, complications, and death based on the FRAIL score were 0.692, 0.740, 0.709, and 0.733, respectively, and those based on the FRAIT score were 0.700, 0.745, 0.708, and 0.724, respectively. The AUCs for predicting operation duration, intraoperative bleeding, complications, and death based on the FRAIL grade were 0.693, 0.735, 0.695, and 0.755, respectively, and those based on the FRAIT grades were 0.700, 0.758, 0.699, and 0.750, respectively. The FRAIL score has three effective predictors (intraoperative bleeding, complications, and death), while the FRAIT score has four effective predictors (operation duration, intraoperative bleeding, complications, and death). The FRAIL grade has two effective predictors (intraoperative bleeding and death), while the FRAIT grade has three effective predictors (operation duration, intraoperative bleeding, and death).

This study describes a new and more effective tool for the assessment of preoperative frailty in older adults undergoing hepatectomy. The items of the FRAIT scale are easier to obtain than those of the FRAIL scale, and the predictive effect of the FRAIT scale is stronger than that of the FRAIL scale.

The potential risk and subsequent impact of serious complications after pancreatic and colorectal surgery can be significantly reduced through early recognition, correct assessment, and timely initiation of appropriate therapy. Serious gaming (SG) is an innovative teaching method that combines play with knowledge acquisition, increased concentration, and quick decision-making and could therefore be used for clinically oriented education.

This study aims to develop a case-based SG platform for complication management in pancreatic and colorectal surgery, validate the application by comparing game courses of various professional groups in the health care sector, and test the acceptance of the developed platform in the context of clinical education by measuring levels of usability and applicability within the framework of a validity and usefulness analysis.

In this observational trial, a novel SG for management of postoperative complications was developed and prospectively validated in a cohort of 131 human caregivers with varying experience in abdominal surgery. A total of 6 realistic patient cases were implemented, representing common complications after pancreatic and colorectal surgery. Cases were developed and illustrated using anonymized images, data, and histories of postoperative patients. In the prospective section of this study, following a brief case presentation, participants were asked to triage the virtual patient, make an initial suspected diagnosis, and design a 3-step management plan, throughout which the results of selected diagnostic and therapeutic actions were presented. Participants' proposed case management was compared to ideal case management according to clinical guidelines. Usability, applicability, validity, and acceptance of the application were assessed using the Trier Teaching Evaluation Inventory as part of a noncomparative analysis. In addition, a comparative analysis of conventional teaching and learning formats was carried out.

A total of 131 cases were answered. Physicians selected more appropriate therapeutic measures than nonphysicians. In the Trier Teaching Evaluation Inventory, design, structure, relevance, timeliness, and interest promotion were predominantly rated positively. Most participants perceived the application to be superior to conventional lecture-based formats (training courses, lectures, and seminars) in terms of problem-solving skills (102/131, 77.9%), self-reflection (102/131, 77.9%), and usability and applicability (104/131, 79.4%).

Case-based SG has educational potential for complication management in surgery and could thereby contribute to improvements in postoperative patient care.

Lung cancer patients will have lung damage after surgery, need rehabilitation exercise. Common-sense model has shown the impact of patients' perception of illness on health behaviors. However, for patients with lung cancer after thoracoscopic surgery, there has been no relevant exploration of disease perception.

The purpose of this study was to investigate the clinical status of patients with lung cancer patients who have undergone thoracoscopic surgery, and to explore the correlation between frailty, disease perception, and lung functional exercise compliance.

The cross-sectional study included 218 patients with lung cancer after thoracoscopic surgery. We collected participants' frailty, disease perception, exercise adherence, and relevant clinical information. T-test, Chi-square, Linear regression, Pearson's correlation, and mediation analysis were used for statistical analysis of patient data.

We analyzed the data by disease perception with high and low median scores and found significant differences in lymphatic dissection, stool within three days, pain, thoracic drainage tube placement time. Linear regression results show that, after controlling for confounding factors, frailty and disease perception were significantly associated with pulmonary function exercise compliance. The higher the frailty score, the worse the compliance, and the higher the disease perception negative score, the less exercise. Illness perception played a partially mediating role in the association between frailty and lung functional exercise adherence.

Frailty and disease perception have an impact on exercise adherence, therefore, we need to consider these factors in the intervention to improve exercise compliance after thoracoscopic surgery for lung cancer.

Although the average life span differs between males and females, little is known about differences in clinical features and short and long-term outcomes between elderly male and female gastric cancer patients. This study was designed to clarify these issues to identify the possibility for sex-based treatment strategies in elderly gastric cancer patients. This study included 295 consecutive elderly gastric cancer patients (75 years or older) who underwent curative gastrectomy between 1997 and 2016. We defined postoperative complications as Clavien-Dindo classification grade II or higher. Comorbidities were present in 67% of all patients. Males tended to have more comorbidities than females (P = 0.077). Male patients had significantly more upper gastric cancers (P = 0.001), a higher incidence of postoperative complications (P = 0.045), and poorer prognoses than females (P = 0.003). Multivariate analysis revealed that being male was an independent risk factor for postoperative complications (Odds ratio 2.5, P = 0.045) and a poor prognostic factor (Hazard ratio 1.81, P = 0.008). Patients who underwent limited surgery without postoperative complications tended to have a better prognosis than patients receiving standard surgery with postoperative complications (3-year overall survival: 78% vs. 55%, P = 0.156). Male was an independent risk factor for postoperative complications and an independent poor prognostic factor in elderly gastric cancer patients. To avoid postoperative complications, the limited surgery might be justified for high-risk elderly male patients.

SBO is a potentially life-threatening condition that often affects older patients. Frailty, more than age, is expected to play a crucial role in predicting SBO prognosis in this population. This study aims to define the influence of Clinical Frailty Scale (CFS) on mortality and major complications in patients ≥80 years with diagnosis of SBO at the emergency department (ED).

All patients aged ≥80 years admitted to our ED for SBO from January 2015 to September 2020 were enrolled. Frailty was assessed through the CFS, and then analyzed both as a continuous and a dichotomous variable. The endpoints were in-hospital mortality and major complications.

A total of 424 patients were enrolled. Higher mortality (20.8% vs 8.6%, p<0.001), longer hospital stay (9 [range 5-14] days vs 7 [range 4-12] days, p=0.014), and higher rate of major complications (29.9% vs 17.9%, p=0.004) were associated with CFS ≥7. CFS score and bloodstream infection were the only independent prognostic factors for mortality (OR 1.72 [CI: 1.29-2.29], p<0.001; OR 4.69 [CI: 1.74-12.6], p=0.002, respectively). Furthermore, CFS score, male sex and surgery were predictive factors for major complications (OR 1.41 [CI: 1.13-1.75], p=0.002; OR 1.67 [CI: 1.03-2.71], p=0.038); OR 1.91 [CI: 1.17-3.12], p=0.01; respectively). At multivariate analysis, for every 1-point increase in CFS score, the odds of mortality and the odds of major complications increased 1.72-fold and 1.41-fold, respectively.

The increase in CFS is directly associated with an increased risk of mortality and major complications. The presence of severe frailty could effectively predict an increased risk of in-hospital death regardless of the treatment administered. The employment of CFS in elderly patients could help the identification of the need for closer monitoring and proper goals of care.

Demand for anesthesia and analgesia for the frail elderly is continuously increasing as the likelihood of encountering very elderly, very vulnerable, and very compromised patients has, ever so subtly, increased over the last three decades. The anesthesiologist has, increasingly, been obliged to offer professional services to frail patients. Fortunately, there has been a dramatic improvement in medications, methods of drug delivery, critical monitoring, and anesthesia techniques. Specific methodologies peculiar to the frail are now taught and practiced across all anesthesia subspecialties. However, administering anesthesia for the frail elderly is vastly different to giving an anesthetic to the older patient. Frail patients are increasingly cared for in specialized units-geriatric intensive therapy units, post-acute care services, palliative, hospices, and supportive care and aged care facilities. Several medications (e.g., morphine-sparing analgesics) more suited to the frail have become universally available in most centers worldwide so that best-practice, evidence-based anesthesia combinations of drugs and techniques are now increasingly employed. Every anesthetic and pain management techniques in the frail elderly patient are going to be discussed in this review.

Healthcare systems continuously strive to improve quality and value of care. Advances in surgical technologies, enhanced perioperative surgical planning, and multidisciplinary care strategies are increasing the number of elective procedures in the geriatric population. However, frail older adults are still more likely to have poor postoperative outcomes. We examined the impact of frailty on postoperative outcomes, we compared the discriminative thresholds for the Risk Analysis Index (RAI), modified Frailty Index-5 (mFI-5), and increasing patient age.

Octogenarian patients undergoing spine, cranial, and other procedures captured in the American College of Surgeons National Surgical Quality Improvement Program between 2012 and 2020 were included. We used receiver operating characteristic curve to examine discriminative thresholds of RAI, mFI-5, and increasing patient age. Multivariable analyses were performed. Our primary outcomes were 30-day mortality, extended length of stay (eLOS [≥75th percentile]), and continued inpatient care >30 days (pLOS). Secondary outcomes were skilled care facility (skilled nursing facility [SNF]) discharges and readmissions.

In total, 20 710 octogenarians were included, with a mean age of 83 years (SD, 2.5) and a men (52.7%) and White (79.8%) majority. The RAI had higher predictive discriminative thresholds for 30-day mortality (C-statistic of 0.743), eLOS (C-statistic: 0.692), and pLOS (C-statistic: 0.697) compared with the mFI-5 (C-statistic: 0.574, 0.556, and 0.550, respectively), and increasing patient age (C-statistic: 0.577, 0.546, and 0.504, respectively), P < .001. On multivariable analyses, RAI showed a larger effect size with adverse postoperative outcomes by increasing frailty strata than mFI-5 and increasing patient age. Nonetheless RAI showed decreased risk for SNF discharges.

We found that RAI was a more accurate predictor than mFI-5 and increasing patient age for 30-day mortality, eLOS, and pLOS in octogenarian neurosurgery patients. More research is needed on RAI's performance in different specialized neurosurgical populations. Moreover, it is increasingly clear that comprehensive risk assessment strategies tailored to optimize perioperative care should be prioritized to potentially improve outcomes for this at-risk population.

Frailty has been globally recognized as a predictor of adverse postoperative outcomes. Frailty assessment using the five-factor modified frailty index (5-mFI) has recently gained traction; however, long-term outcomes are unknown in colorectal cancer (CRC) surgery. This study aimed to investigate whether the 5-mFI predicted long-term survival and cause of death on the basis of frailty severity in elderly patients who underwent CRC surgery and to determine the risk factors for mortality.

A total of 299 patients underwent CRC surgery with curative intent between January 2013 and December 2017. Patients were divided into three groups by the 5-mFI score: group 1 (5-mFI: 0 or 1; n = 164): no frailty; group 2 (5-mFI: 2; n = 91): moderate frailty; and group 3 (5-mFI: ≥ 3; n = 44): severe frailty. Clinicopathological variables, namely comorbidities, 5-mFI, prognostic nutrition index, operative/postoperative data, and outcome, including cause of death, were compared between the three groups. To identify factors associated with death from CRC- and non-CRC-related causes, univariate and multivariate analyses using a Cox regression model were performed.

The immediate postoperative morbidity of patients with Clavien-Dindo grade ≥ III complications (9.1%) in group 3 was not significantly different from that in group 1 (9.1%) or group 2 (14.3%); however, the 30-day mortality rate (4.5%) in group 3 was significantly higher. Long-term disease-free survival was similar between frailty groups, suggesting that CRC surgery provides oncological benefit to patients irrespective of frailty. The 5-year survival rates in groups 1, 2, and 3 were 83.5%, 71.2%, and 47.9%, respectively, showing a significantly lower survival rate as frailty advanced. Sixty percent of the deaths in frail patients were due to respiratory failure and cardiovascular diseases. Multivariate analysis demonstrated that advanced age, higher 5-mFI score, and longer postoperative hospital stay were risk factors for mortality unrelated to CRC. Multivariate analysis also revealed that advanced tumor stage, carcinoembryonic antigen ≥ 5 ng/ml, undifferentiated tumor, and R1 resection were risk factors for CRC-related mortality.

The 5-mFI score can predict postoperative short- and long-term outcomes and risk factors for mortality unrelated to CRC. Additionally, long-term survival was negatively associated with the 5-mFI score.

(1) Background: In the treatment of colorectal cancer, it is important to consider different psychosocial factors. Our first objective was to measure the levels of perceived stress in subjects diagnosed with colorectal cancer awaiting potentially curative surgery. Also, we aimed to analyse what coping styles these patients used, how they perceived their illness, and the subsequent influence of these factors on their levels of stress. (2) Methods: Stress, coping styles and illness perception were assessed in a sample of 107 patients. The instruments used were the Perceived Stress Scale (PSS-14), the Stress Coping Questionnaire (SCQ) and the Brief Illness Perception Questionnaire (BIPQ-R). (3) Results: Patients using active coping styles have lower levels of perceived stress (p = 0.000; p = 0.002) than patients making use of passive coping styles (p = 0.000; p = 0.032; p = 0.001). A multi-linear regression model found that the perception of illness and the use of the negative approach coping style (p = 0.000; p = 0.001) influence an increase in perceived stress, and that a decrease in stress levels was influenced by the problem solving coping style (p = 0.001). (4) Conclusions: Based on our results, we recommend preventive interventions in care patients undergoing colorectal cancer surgery.

Management of postoperative pulmonary complications (PPCs) can be challenging in gastric cancer patients undergoing radical gastrectomy and is always associated with poor prognosis. Even though oncology nurse navigator (ONN) provide effective and critical individualized care to patients, little is known about their impact on the occurrence of PPCs in gastric cancer patients. This study aimed to determine whether ONN decreases the incidence of PPCs in gastric cancer patients.

This was a retrospective review in which data for gastric cancer patients at one centre was evaluated before and after an ONN hired. An ONN was introduced to patients at their initial visit to manage pulmonary complications throughout treatment. The research was conducted from 1 August 2020 to 31 January 2022. The study participants were divided into the non-ONN group (from 1 August 2020 to 31 January 2021) and the ONN group (from 1 August 2021 to 31 January 2022). The incidence and severity of PPCs between the groups were then compared.

ONN significantly decreased the incidence of PPCs (15.0% vs. 9.8%) (OR = 2.532(95% CI: 1.087-3.378, P = 0.045)), but there was no significant difference in the components of PPCs including pleural effusion, atelectasis, respiratory infection, and pneumothorax. The severity of PPCs was also significantly higher in the non-ONN group (p = 0.020). No significant statistical difference was observed for the major pulmonary complications ([Formula: see text] 3) between the two groups (p = 0.286).

Role of ONN significantly decrease the incidence of PPCs in gastric cancer patients undergoing radical gastrectomy.

To evaluate, in a prospective observational cohort study of adults ≥65 years old, the frailty status at the emergency department (ED) admission for the in-hospital death risk stratification of patients needing urgent cholecystectomy.

Clinical variables and frailty status assessed in the ED were evaluated for the association with major complications and the need for open surgery. The parameters evaluated were frailty, comorbidities, physiological parameters, surgical approach, and laboratory values at admission. Logistic regression analysis was used to identify independent risk factors for poor outcomes.

The study enrolled 358 patients aged ≥65 years [median age 74 years]; 190 males (53.1%)]. Overall, 259 patients (72.4%) were classified as non-frail, and 99 (27.6%) as frail. The covariate-adjusted analysis revealed that frailty (P< 0.001), and open surgery (P = 0.015) were independent predictors of major complications. Frailty, peritonitis, constipation at ED admission, and Charlson Comorbidity Index ≥ 4 were associated with higher odds of open surgical approach (2.06 [1.23 - 3.45], 2.49 [1.13 - 5.48], 11.59 [2.26 - 59.55], 2.45 [1.49 - 4.02]; respectively).

In patients aged ≥65 years undergoing urgent cholecystectomy, the evaluation of functional status in the ED could predict the risk of open surgical approach and major complications. Frail patients have an increased risk both for major complications and need for "open" surgical approach.

To investigate the acceptability and safety of neuromuscular stimulation (NMES) as an adjunct for rehabilitation after vascular and general surgery.

Prospective, single-centre, single-blind, parallel group, randomised controlled study. This study will be conducted in a single-centre, secondary care setting (National Healthcare Service Hospital) in the UK. All patients aged over 18 years undergoing vascular or general surgery with Rockwood Frailty Score of 3 or above on admission. Exclusion is inability or unwillingness to participate in trial, implanted electrical device, pregnancy and acute deep vein thrombosis. Target number of recruitment is 100. Participants will be randomly assigned to active NMES group (group A) or placebo NMES group (group B) prior to surgery. Participants will be blinded and asked to use the NMES device, 1-6 sessions daily (30 min per session) after surgery in addition to standard National Health Service rehabilitation care until discharge. The primary study outcomes are acceptability and safety of NMES assessed by the device satisfaction questionnaire on discharge and adverse events recorded during hospital stay. The secondary outcomes are the postoperative recovery and cost-effectiveness compared between two groups, assessed by various activity tests, mobility and independence measures and questionnaires.

Ethical approvals were provided by London-Harrow Research Ethics Committee (REC) and the Health Research Authority (HRA), Ref: 21/PR/0250. Findings will be published in a peer-reviewed journal and presented at national and international conferences.

Preoperative nutrition status is an important determinant of surgical outcomes, yet malnutrition assessment is not integrated into all surgical pathways. Given its importance and the high prevalence of malnutrition in patients undergoing surgical procedures, preoperative nutrition screening, assessment, and intervention are needed to improve postoperative outcomes. This narrative review discusses novel methods to assess malnutrition and frailty in the surgical patient. The Global Leadership Initiative for Malnutrition (GLIM) criteria are increasingly used in surgical settings although further spread and implementation are strongly encouraged to help standardize the diagnosis of malnutrition. The use of body composition (ie, reduced muscle mass) as a phenotypic criterion in GLIM may lead to a greater number of patients identified as having malnutrition, which may otherwise be undetected if screened by other diagnostic tools. Skeletal muscle loss is a defining criterion of malnutrition and frailty. Novel direct and indirect approaches to assess muscle mass in clinical settings may facilitate the identification of patients with or at risk for malnutrition. Selected imaging techniques have the additional advantage of identifying myosteatosis (an independent predictor of morbidity and mortality for surgical patients). Feasible pathways for screening and assessing frailty exist and may determine the cost/benefit of surgery, long-term independence and productivity, and the value of undertaking targeted interventions. Finally, the evaluation of nutrition risk and status is essential to predict and mitigate surgical outcomes. Nascent to novel approaches are the future of objectively identifying patients at perioperative nutrition risk and guiding therapy toward optimal perioperative standards of care.

 Age is a poor predictor of postoperative outcomes in breast reconstruction necessitating new methods for risk-stratifying patients preoperatively. The 5-item modified frailty index (mFI-5) is a validated measure of frailty which assesses patients' global health. The purpose of this study was to compare the effectiveness of mFI-5 and age as independent predictors of 30-day postoperative complications following autologous breast reconstruction.

 Patients who underwent autologous breast reconstruction between 2005 and 2019 were identified from the American College of Surgeons National Surgical Quality Improvement Program. Patients were stratified based on presence of major, minor, both minor and major, and no complications. Univariate and multivariate logistic regression were performed to determine the predictive power of mFI-5, age, and other preoperative risk factors for development of minor and major 30-day postoperative complications in all patients and stratified by flap type.

 A total of 25,215 patients were included: 20,366 (80.8%) had no complications, 2,009 (8.0%) had minor complications, 1,531 (6.1%) had major complications, and 1,309 (5.2%) had both minor and major complications. Multivariate regression demonstrated age was not a predictor of minor (odds ratio [OR]: 1.0, p = 0.045), major (OR: 1.0, p = 0.367), or both minor and major (OR: 1.0, p = 0.908) postoperative complications. mFI-5 was a significant predictor of minor complications for mFI-5 scores 1 (OR: 1.3, p < 0.001), 2 (OR: 1.8, p < 0.001), and 3 (OR: 2.8, p = 0.043). For major complications, mFI-5 was a significant predictor for scores 1 (OR: 1.2, p = 0.011) and 2 (OR: 1.3, p = 0.03).

 Compared with age, mFI-5 scores were better predictors of 30-day postoperative complications following autologous breast reconstruction regardless of flap type. Additionally, higher mFI-5 scores were associated with increased odds of minor and major complications. Our findings indicate that reconstructive breast surgeons should consider using the mFI-5 in lieu of age to risk-stratify patients prior to autologous breast reconstruction surgery.

Previous studies suggested that tumor size was an independent risk factor of prognosis for hepatocellular carcinoma (HCC). However, the general prognostic analysis did not consider the interaction between variables. The purpose of this study was to investigate whether the effect of tumor size on the prognosis of isolated HCC without vascular invasion varies according to covariates.

Patients were selected from the Surveillance, Epidemiology, and End Results (SEER) database to investigate whether there was an interaction between age and tumor size on the prognosis. Then the trend test and the value of per 1 SD of tumor size were calculated. In addition, the data of Zhejiang Provincial People's Hospital meeting the requirements were selected to verify the obtained conclusions.

Multivariable Cox regression analysis of the database cohort showed that age, gender, tumor size, pathological grade and marital status were independent risk factors for prognosis. Interaction test showed that there was an interaction between age and tumor size (P for interaction < 0.05). Stratified analysis by age showed that tumor size was an independent risk factor for prognosis when age ≤65 years old (HR:1.010,95%CI1.007-1.013 P < 0.001), while tumor size was not an independent risk factor for prognosis when age >65 years old. This result was confirmed by trend analysis (P for trend < 0.001), and the prognostic risk increased by 42.1% for each standard deviation increase of tumor size among patients age ≤65 years. Consistent conclusion was obtained by multivariable cox regression analysis and interaction test on the verification cohort. In the validation cohort, for each standard deviation increase of tumor size in patients ≤65 years old, the risk of prognosis increased by 52.4%.

Tumor size is not an independent risk factor for the prognosis of isolated HCC without vascular invasion when patient's age >65 years. Therefore, when analyzing the relationship between tumor size and prognosis, stratified analysis should be performed according to age.

Measurement of frailty with the Risk Analysis Index (RAI) has demonstrated improved outcome prediction compared to other frailty indices across the surgical literature. However, the generalizability and clinical utility of preoperative RAI scoring for prediction of postoperative morbidity after adult spinal deformity surgery is presently unknown. Thus, recent studies have called for an RAI analysis of spine deformity outcomes.

The present study sought to evaluate the discriminatory accuracy of preoperative frailty, as measured by RAI, for predicting postoperative morbidity among adult spine deformity surgery patients using data queried from a large prospective surgical registry representing over 700 hospitals from 49 US states and 11 countries.

Secondary analysis of a prospective surgical registry.

American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database (2011-2020).

The primary endpoint was "adverse discharge outcome" (ADO) defined as discharge to a non-home, non-rehabilitation nursing/chronic care facility.

Adult spine deformity surgeries were queried from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database (2011-2020) using diagnosis and procedure codes. The relationship between increasing preoperative RAI frailty score and increasing rate of primary endpoint (ADO) was assessed with Cochran-Armitage linear trend tests. Discriminatory accuracy was tested by computation of concordance statistics (with 95% confidence interval [CI]) in receiver operating characteristic (ROC) curve analysis.

A total of 3,104 patients underwent spine deformity surgery and were stratified by RAI score: 0-10: 22%, 11-15: 11%, 16-20: 29%, 21-25: 26%, 26-30: 8.0%, 31-35: 2.4%, and 36+: 1.4%. The rate of ADO was 14% (N=439/3094). The rate of ADO increased significantly with increasing RAI score (p<.0001). RAI demonstrated robust discriminatory accuracy for prediction of ADO in ROC analysis (C-statistic: 0.71, 95% CI: 0.69-0.74, p<.001). In pairwise comparison of ROC curves (DeLong test), RAI demonstrates superior discriminatory accuracy compared to the 5-factor modified frailty index (mFI-5; p<.001).

Preoperative frailty, as measured by RAI, is a robust predictor of postoperative morbidity (measured by ADO) after adult spine deformity surgery. The frailty score may be translated directly to the bedside with a user-friendly risk calculator, deployed here: https://nsgyfrailtyoutcomeslab.shinyapps.io/spineDeformity.

Frailty is common in older cancer patients undergoing colorectal surgery, but few studies have focused on frailty and its associations in this population.

The aim of this study was to investigate the prevalence of frailty and its associations in older cancer patients undergoing colorectal surgery.

A convenience sample of 88 cancer patients 60 years or older undergoing colorectal surgery was recruited from 1 medical center. Frailty, physical activity, functional status, anxiety, depression, and social support of the patients were assessed before surgery, at discharge post surgery, and at 1 month post surgery.

The prevalence of frailty in cancer patients undergoing colorectal surgery was 22.7% before surgery, decreased to 19.3% before discharge, and was 12.7% at 1 month after surgery. The proportion of prefrail patients significantly increased from 47.7% before surgery to 71.1% before discharge and was 64.6% at 1 month after surgery. Frail patients were more likely to be older and unmarried, have a lower albumin level, have lower physical activity, and be more dependent on others than nonfrail patients.

Older cancer patients undergoing colorectal surgery were more likely to be prefrail after surgery than before surgery. Assessment of frailty and its associated factors is necessary for older cancer patients undergoing colorectal surgery before and after surgery.

Frailty may occur in cancer patients after colorectal surgery and is related to malnutrition and low physical activity. Appropriate discharge planning with physical activity tracking and an appropriate diet is encouraged to prevent frailty in cancer patients after colorectal surgery.

Preoperative carbohydrate drinks are recommended to reduce fasting time before surgery. Older adults are at risk of pulmonary aspiration and hyperglycemia after consuming carbohydrate drinks because of increased insulin resistance and delayed gastric emptying. We investigated the effects of oral carbohydrate drinks on perioperative insulin resistance, metabolic responses, and gastric volume in older adults.

Fifty-six patients (aged more than 65 years) were randomly assigned to the control or carbohydrate (CHO) group. The CHO group received 400 mL of a carbohydrate drink 2 to 3 hours before anesthesia. The control group was allowed clear fluid intake 2 hours before anesthesia. Blood glucose and insulin levels were measured before intake of the carbohydrate drink and 1 hour postoperatively. Gastric volume was measured before spinal anesthesia. Insulin resistance was calculated using the homeostasis model assessment for insulin resistance.

Homeostasis model assessment for insulin resistance was not different between the control and CHO groups preoperatively (2.5 versus 3.3, P = 0.156) or postoperatively (2.6 versus 2.4, P = 0.817). Preoperative gastric volume was comparable between the control and CHO groups (35.5 versus 30.8 mL, P = 0.696).

Preoperative oral consumption of carbohydrates did not affect insulin resistance or gastric volume in older adults undergoing total knee or hip arthroplasty. Preoperative carbohydrate loading is safe in older adults undergoing total knee or hip arthroplasty.
