Perioperative management in diabetic patients is important since their postoperative mortality and morbidity are higher than that of non-diabetic patients, which will exacerbate the burden on public health. We selected relevant publications from the WoSCC-SCIE between 2007 and 2024, utilizing VOSviewer and CiteSpace to analyze the collected information and generate knowledge maps. A total of 3167 articles from 792 journals and 83 countries/regions were included for analysis. Overall, there has been a continuous increase in publication volume. From the result of academic collaboration between different countries/regions and institutions, the USA occupies a central position in research strength. A total of 18,101 authors participated in research on "perioperative management in diabetic patients" with Dr. Guillermo E. Umpierrez from Emory University School of Medicine being the most productive author. We conclude that perioperative adverse clinical outcomes in diabetic patients and perioperative blood glucose management have consistently been research hotspots in this field. Additionally, continuous glucose monitoring and insulin administration under computer guidance, as well as the use of merging medications are likely to be frontier directions for future research. Research on perioperative care for diabetic patients has been further deepened worldwide, which will be crucial in further improving perioperative care for diabetic patients and enhancing postoperative recovery.

The optimal glucose control strategy for intensive care unit (ICU) patients with diabetes remains a topic of debate. This study aimed to compare the effects of strict glucose control, intermediate strict glucose control, liberal glucose control, and very liberal glucose control on reducing all-cause mortality in ICU patients with diabetes through a network meta-analysis.

We conducted a search in PubMed, Cochrane Library, Embase, and Web of Science for randomized controlled trials comparing different glucose control strategies in ICU patients with diabetes up to October 1, 2024. The primary outcome was all-cause 90-day mortality. The Risk of Bias 2 tool was used to assess bias in the included studies. Data analysis was performed using Stata (version 17).

A total of 12 randomized controlled trials involving 5,297 participants were included in the final analysis. The results showed that there was no statistically significant difference between the four glucose control strategies in reducing all-cause 90-day mortality. The surface under the cumulative ranking (SUCRA), which was used to rank the strategies and display the probability of each strategy being ranked first, showed the following: intermediate strict control (SUCRA 88%), liberal control (SUCRA 55.3%), very liberal control (SUCRA 40.3%), and strict control (SUCRA 16.5%). The cumulative probability of each strategy's rank in reducing all-cause mortality, from best to worst, showed that the most likely ranking was intermediate strict control, liberal control, very liberal control, and strict control.

In ICU patients with diabetes, no significant statistical difference was observed among the four glucose control strategies in reducing all-cause 90-day mortality. The SUCRA rankings are hypothesis-generating and require further validation. Therefore, the current evidence is insufficient to definitively conclude that any one strategy is superior to the others in reducing mortality.

Hyperglycemia is a common and challenging condition in hospitalized patients both with and without a history of diabetes. Managing hyperglycemia effectively is critical in reducing complications, mortality, and the length of hospital stays. Insulin degludec (IDeg), an ultralong-acting basal insulin, has a well-established efficacy and safety profile in terms of managing hyperglycemia in outpatients; it has demonstrated benefits in clinical practice across various patient populations. This review aims to assess the evidence on its clinical suitability, as well as efficacy and safety, for managing hyperglycemia across different inpatient populations. The review specifically focuses on outcomes such as glycemic control, glycemic variability, safety (particularly hypoglycemia risk), dosing flexibility, ease of titration, and use in special populations.

A comprehensive literature search was conducted using PubMed to identify studies published between 2014 and 2024. Eligible studies included randomized controlled trials, real-world evidence, and case series that examined the use of IDeg for hyperglycemia management in hospitalized patients.

The reviewed studies consistently demonstrated that IDeg provides stable and predictable glycemic control with low glycemic variability. The ultralong duration of action, ability to be titrated daily, and flexibility in dosing make IDeg suitable for noncritical care settings with difficult-to-maintain rigid insulin schedules. Furthermore, the risk of hypoglycemia, particularly nocturnal hypoglycemia, is low with IDeg. These attributes are beneficial across diverse inpatient populations. Practical advantages, such as ease of administration with a specialized delivery device, further support its use in hospital settings.

Unique pharmacokinetic and pharmacodynamic properties of IDeg, reduced glycemic variability, low hypoglycemia risk, ease of daily titration, and dosing flexibility make it appropriate for managing hyperglycemia in hospitalized patients.

To summarize the clinical evidence on nutritional support for critically ill patients, the (patho)physiological mechanisms involved, and areas of future research.

Large randomized controlled trials have shown that early nutrition induces dose-dependent harm in critically ill patients, regardless of the feeding route, and that early high-dose amino acids are harmful. Harm has been attributed to feeding-induced suppression of cellular repair pathways including autophagy and ketogenesis, to aggravation of hyperglycemia and insulin needs, and to increased urea cycle activity. Additionally, acute critical illness was shown to be a state of anabolic resistance. The absence of benefit of early enhanced nutritional support on short- and long-term outcomes was observed in all studied subgroups.

While early high-dose nutrition should be avoided in all critically ill patients, the optimal initiation time of nutrition support for the individual patient, as well as ideal composition and dosing of nutrition over time remain unclear. Future studies should elucidate how fasting-induced repair pathways can be activated while avoiding prolonged starvation, and how hyperglycemia and high insulin need could be prevented. Potential strategies include intermittent fasting, ketogenic diets, ketone supplements, and alternative glucose-lowering agents, whether or not in combination with exercise.

Acute pancreatitis (AP) is an inflammatory reaction of the pancreas. When the disease is severe, it is often accompanied by destruction of the pancreatic islets, resulting in dysfunction of the endocrine system of the pancreas. Stress hyperglycemia is a transient increase in glucose during a critical illness, and its possible mechanism is related to abnormal glucose metabolism and insulin resistance due to the increased release of counterregulatory hormones and cytokines, such as glucagon, cortisol, and catecholamines. Numerous studies have shown that stress hyperglycemia is strongly associated with morbidity, mortality, and increased risk of post-acute pancreatitis diabetes in AP patients. Therefore, stress hyperglycemia may be a significant independent risk factor for poor clinical outcomes and prognosis in patients with AP. This article reviews the clinical features, risk factors, and mechanisms of action of stress hyperglycemia in AP and its influence on adverse clinical outcomes and the prognosis of inpatients with AP. For AP patients with stress hyperglycemia, it is necessary to comprehensively consider their blood glucose levels, daily habits, and complications to develop an appropriate treatment plan for hyperglycemia. Limited evidence indicates that in the case of acute hyperglycemia in critically ill patients, especially during the first 3 days of hospitalization, insulin therapy should not be undertaken if the blood glucose level does not exceed 10 mmol/L. However, some important questions related to clinical practice remain to be answered. More clinical trials and studies are needed in the future to provide a sufficient basis for clinical practice.

The 2024 revised edition of the Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock (J-SSCG 2024) is published by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine. This is the fourth revision since the first edition was published in 2012. The purpose of the guidelines is to assist healthcare providers in making appropriate decisions in the treatment of sepsis and septic shock, leading to improved patient outcomes. We aimed to create guidelines that are easy to understand and use for physicians who recognize sepsis and provide initial management, specialized physicians who take over the treatment, and multidisciplinary healthcare providers, including nurses, physical therapists, clinical engineers, and pharmacists. The J-SSCG 2024 covers the following nine areas: diagnosis of sepsis and source control, antimicrobial therapy, initial resuscitation, blood purification, disseminated intravascular coagulation, adjunctive therapy, post-intensive care syndrome, patient and family care, and pediatrics. In these areas, we extracted 78 important clinical issues. The GRADE (Grading of Recommendations Assessment, Development and Evaluation) method was adopted for making recommendations, and the modified Delphi method was used to determine recommendations by voting from all committee members. As a result, 42 GRADE-based recommendations, 7 good practice statements, and 22 information-to-background questions were created as responses to clinical questions. We also described 12 future research questions.

Critically ill children requiring treatment in a pediatric intensive care unit (PICU) suffer from anorexia and/or feeding intolerance. The resulting macronutrient deficit associates with poor outcome. Until recently, this association formed the basis for initiating enteral or parenteral feeding early to improve outcome. The multicenter "Early-versus-Late-Parenteral-Nutrition-in-the-Pediatric-Intensive-Care-Unit" randomized controlled trial (PEPaNIC-RCT) addressed whether this association is causal. It showed that early supplementation of insufficient/contraindicated enteral nutrition with parenteral nutrition, as compared with accepting a macronutrient deficit throughout the first week in the PICU, did not improve outcome. On the contrary, it caused more infections and prolonged organ support and PICU stay, and adversely affected neurodevelopmental outcomes 2 and 4 years later. Harm was present in all subgroups and appeared explained by the macronutrient dose, more specifically the amino-acid dose, not lipid or glucose doses. These findings corroborated results from large-scale adult RCTs. Mechanisms of harm from early enhanced nutrition comprised suppressed cellular repair pathways like autophagy and ketogenesis, suppressed illness-induced alterations in thyroid hormone metabolism, more iatrogenic hyperglycemia, increased urea cycle activity through anabolic resistance, and induction of epigenetic modifications that mediate longer-term developmental impairments. These results came unexpected to many pediatric intensivists. Hence, the paradigm has only slowly begun to shift toward more restrictive macronutrient administration in the acute phase of critical illness. Benefits of early fasting responses have become clear, provided micronutrients are given to prevent deficiencies and refeeding syndrome. These insights open perspectives for studies investigating novel nutritional strategies to activate fasting-induced cellular repair while avoiding prolonged starvation.

Low blood glucose levels and high urea nitrogen levels affect patient prognosis, but few studies have investigated whether the blood urea nitrogen to glucose (BGR) ratio predicts the risk of death.This retrospective research examined the connection between the BGR and 365-day mortality in patients with chronic kidney disease (CKD) stages 1-4 admitted to an intensive care unit (ICU). The study utilized data from 6,380 patients in the Medical Information Mart for Intensive Care IV version 2.2 (MIMIC-IV v2.2), taking into account confounding factors such as demographics, vital signs, laboratory indicators, and comorbidities. The study employed both univariate and multivariate Cox regression analyses stratified by BGR quartiles. Additionally, restricted cubic spline regression and inflection point analysis were used to explore the linear relationship between BGR and 365-day mortality, while Kaplan-Meier curve analysis was used to observe mortality changes under different BGR stratifications. Subgroup and mediating effect analyses were performed to evaluate the robustness of BGR's effect on 365-day mortality. The study found a cumulative 365-day mortality rate of 34.2% among CKD stages 1-4 patients, with a 2.43-fold increase in the risk of death associated with BGR and at least a 44% increase in the risk of death for each unit increase in BGR (P = 0.022). A significant nonlinear relationship was identified, showing a stepwise change in the risk of death with a marked increase in the slope of the curve for BGR values below 0.52 and above 0.9 (P < 0.001). Subgroup analyses indicated interactions between BGR and factors such as age, sepsis, first-day antibiotic use, and cerebrovascular disease (P < 0.05). In conclusion, this study confirms that BGR is a significant and stable predictor of 1-year mortality risk in patients with CKD stages 1-4. Interventions aimed at timely adjustment, correction of metabolic imbalances, reduction of inflammation, and management of BGR levels are beneficial for reducing mortality in this patient population.

Most current guideline statements support some level of unrestricted glycemic management in critically ill adult patients. Nevertheless, the effectiveness of liberal glucose control is currently not well-supported by evidence. Therefore, our objective is to investigate the influence of liberal glucose control (> 180 mg/dl) on critically ill patients in the intensive care unit (ICU).

Until November 23, 2023, English language literature was thoroughly and systematically searched through multiple databases, including PubMed, Embase, Cochrane Library, and Web of Science. Our primary endpoints of interest were the occurrence of hypoglycemia, mortality in the ICU, and mortality during hospitalization. In addition, our secondary outcomes comprised of 90-day mortality, bloodstream infections, the proportion of patients necessitating renal replacement therapy (RRT), the length of time under mechanical ventilation, duration of stay in the ICU, and length of the overall hospitalization. Weighted mean difference (WMD) and relative risk (RR) were respectively computed as overall effect size for continuous and dichotomous data and reported with their 95% confidence intervals (95% CI).

A total of 9 studies were incorporated, which included 14,878 patients in the ICU. Compared with other blood glucose target control groups, liberal glucose control significantly reduced the incidence of hypoglycemia (RR = 0.41; 95% CI:0.25 to 0.69; P = 0.001), but increased ICU mortality (RR = 1.23; 95% CI:1.03 to 1.48; P = 0.023), in-hospital mortality risk (RR = 1.18; 95% CI:1.03 to 1.35; P = 0.020), and the risk of requiring RRT (RR = 1.26; 95% CI:1.11 to1.42; P < 0.001).

Liberal glucose control can reduce the risk of hypoglycemia but increases the risks of ICU mortality, in-hospital mortality, and the requirement for RRT. To confirm the outcomes further, large-scale, high-quality clinical trials are necessary.

During critical illness, patients experience significant and rapid onsets of muscle wasting and dysfunction with loss of strength, mass, and power. These deficits often persist long after the ICU, leading to impairments in physical function including reduced exercise capacity and increased frailty and disability. While there are numerous studies describing the epidemiology of impaired muscle and physical function in the ICU, there are significantly fewer data investigating mechanisms of prolonged and persistent impairments in ICU survivors. Additionally, while several potential clinical risk factors associated with poor physical recovery have been identified, there remains a dearth of interventions that have effectively improved outcomes long-term among survivors. In this article, we aim to provide a thorough, evidence-based review of the current state of knowledge regarding muscle dysfunction and physical function after critical illness with a focus on post-ICU and post-hospitalization phase of recovery.

Acute kidney injury (AKI) is a complex clinical syndrome characterized by a rapid decline in kidney function, often resulting in complex metabolic and hormonal derangements. A major concern in managing AKI patients is the development of protein energy wasting (PEW), a condition marked by loss of lean body mass and negative impact on overall health outcomes. Additionally, the need of Kidney Replacement Therapy (KRT) for the most severe forms of AKI may further increase the risk of PEW, with a substantial impact on fluid and metabolic balance. Adequate nutritional support is crucial in the management of AKI, as it plays a pivotal role in muscle mass preservation, morbidity reduction and recovery of renal function. This paper aims to evaluate the current evidence regarding nutritional strategies in AKI patients, focusing on energy and protein requirements, timing and route of nutritional intervention, and impact of individualized nutrition plans on PEW prevention and management.

Glycemic control is a major concern during critical illness. Several prospective studies have yielded conflicting results regarding its mortality effect. Current recommendations are to initiate insulin therapy for all patients when glucose levels are higher than 180 mg/dL. Some suggest decreasing this threshold for non-diabetic patients to 140 mg/dL. These thresholds haven't been compared to each other or to other glucose thresholds. This study aimed to find out whether different glucose levels are associated with 90-d mortality.

A retrospective cohort study. Critically ill patients who were admitted from 2019 to 2022 to a mixed medical-surgical intensive care unit for more than 48 h were included. Collected data included baseline characteristics, and all glucose levels recorded (time-indexed to the admission time). Glucose levels were considered constant until the following glucose level. The percentage of time above several chosen glucose cutoff levels was calculated and analyzed for mortality adjusted to other baseline covariates.

45,512 glucose measurements of 1429 patients were included in the study; 21.76 % of the patients had diabetes. Mean glucose level and glucose variability were higher in diabetic patients (165.86 mg/dL vs 135.47 mg/dL, p < 0.0001, and 30.81 % vs 20.86 %, p < 0.0001, respectively), along with a higher incidence of hypoglycemia (40.84 % vs 24.89 %, p < 0.001). 90-d mortality was higher in diabetic patietns (42.12 % vs 32.41 %, p = 0.0014) and was found associated with age, acute physiology and chronic health evaluation 2 score, medical or surgical admission reasons. Percentage of time above cutoffs ≥150 mg/dL was associated with 90-d mortality only in non-diabetic patients.

In non-diabetic patients, hyperglycemia greater than 150 mg/dL, was associated with increased 90-day mortality.

Prior research has indicated that adopting strict glycemic control measures might elevate the risk of hypoglycemia and result in higher mortality rates among critically ill patients. However, there is a lack of studies investigating the incidence of hypoglycemia and its consequential outcomes in real-world clinical settings. This retrospective cohort study was conducted at Taichung Veterans General Hospital, utilizing critical care databases covering the period from 2015 to 2020. The objective was to examine the outcomes and identify risk factors associated with hypoglycemia in critically ill patients. Out of the total of 16,699 patients admitted to the intensive care units (ICUs), 2,115(12.7%) experienced at least one episode of hypoglycemia were included in the analysis. Critically ill patients who developed hypoglycemia had a significantly higher hospital mortality rate compared to those who did not experience hypoglycemia. (48.9% vs. 15.9%, p < 0.001). Moreover, patients with more severe hypoglycemia exhibited a higher mortality rate (moderate hypoglycemia: hazard ratio [HR] 1.477, 95% confidence interval [C.I.] 1.351-1.614, p < 0.001; severe hypoglycemia: HR 1.847, 95% C.I. 1.607-2.123, p < 0.001) compared to those without hypoglycemia. Additionally, patients with greater frequency of hypoglycemic episodes also showed a higher mortality rate (one episode HR 1.504, 95% C.I. 1.366-1.657, p < 0.001; multiple episodes HR 1.613, 95% C.I. 1.444-1.801, p < 0.001) compared to those without hypoglycemia. Patient who experienced spontaneous hypoglycemia (53.9% vs. 42.4%, p < 0.001) and those without a prior diagnosis of diabetes (60.2% vs. 37.0%, p < 0.001) had higher mortality rate. Hypoglycemia frequently occurs and serves as an independent risk factor for mortality among critically ill individuals, particularly in cases of severe and recurrent episodes. Patients experiencing spontaneous hypoglycemia, as well as those lacking a diabetes diagnosis, demonstrated elevated mortality rates.

Severe sepsis is cognate with life threatening multi-organ dysfunction. There is a disturbance in endocrine functions with alterations in several hormonal pathways. It has frequently been linked with dysfunction in the hypothalamic pituitary-adrenal axis (HPA). Increased cortisol or cortisolemia is evident throughout the acute phase, along with changes in the hypothalamic pituitary thyroid (HPT) axis, growth hormone-IGF-1 axis, insulin-glucose axis, leptin, catecholamines, renin angiotensin aldosterone axis, ghrelin, glucagon, hypothalamic pituitary gonadal (HGA) axis, and fibroblast growth factor-21. These changes and metabolic alterations constitute the overall response to infection in sepsis. Further research is essential to look into the hormonal changes that occur during sepsis, not only to understand their potential relevance in therapy but also because they may serve as prognostic indicators.

Intraoperative hypoglycemia is presumed to be rare, but generalizable multicentre incidence and risk factor data for adult patients are lacking. We used a multicentre registry to characterize adults with intraoperative hypoglycemia and hypothesized that intraoperative insulin administration would be associated with hypoglycemia.

We conducted a cross-sectional retrospective multicentre cohort study. We searched the Multicenter Perioperative Outcomes Group registry to identify adult patients with intraoperative hypoglycemia (glucose < 3.3 mmol·L-1 [< 60 mg·dL-1]) from 1 January 2015 to 31 December 2019. We evaluated characteristics of patients with intraoperative glucose measurements and with intraoperative hypoglycemia.

Of 516,045 patients with intraoperative glucose measurements, 3,900 (0.76%) had intraoperative hypoglycemia. Diabetes mellitus and chronic kidney disease were more common in the cohort with intraoperative hypoglycemia. The odds of intraoperative hypoglycemia were higher for the youngest age category (18-30 yr) compared with the odds for every age category above 40 yr (odds ratio [OR], 1.57-3.18; P < 0.001), and were higher for underweight or normal weight patients compared with patients with obesity (OR, 1.48-2.53; P < 0.001). Parenteral nutrition was associated with lower odds of hypoglycemia (OR, 0.23; 95% confidence interval [CI], 0.11 to 0.47; P < 0.001). Intraoperative insulin use was not associated with hypoglycemia (OR, 0.996; 95% CI, 0.91 to 1.09; P = 0.93).

In this large cross-sectional retrospective multicentre cohort study, intraoperative hypoglycemia was a rare event. Intraoperative insulin use was not associated with hypoglycemia.

Hyperglycemia is a serious condition and associated with an increased risk of complications and mortality in both critically ill and non-critically ill people. Improvement in the glycemic level reduces the length of hospital stay, systemic infections and short- and long-term mortality. The aim was to test the effectiveness of insulin degludec vs insulin glargine and regular insulin in controlling blood sugar in patients with critical hyperglycemia.

Using random control trial, the patients were randomly divided into three equal groups-group R, group G and group D. Each group included 30 patients. Group G was managed using regular insulin together with an insulin glargine. Group D was managed using regular insulin together with an insulin degludec. However, group R was managed using only regular insulin.

The incidence of hypoglycemia was statistically more significant in the group of regular insulin than in groups G and group D with a p-value 0.0069. There was no statistically significant difference between the three groups regarding the frequency of hypoglycemia.

Ultra-long-acting insulin can effectively control random blood sugar (RBS) with a decrease in the total dose of insulin used. It is recommended that using insulin degludec is a safe and effective alternative to regular insulin for glycemic control in critically ill patients.

To systematically evaluate risk factors for stress-induced hyperglycemia in patients without diabetes after cardiac surgery.

Databases including CNKI, WanFang data, VIP, SinoMed, PubMed, Web of Science, Embase, and the Cochrane Library were searched using computer retrieval. The data were subjected to an in-depth meta-analysis using RevMan 5.4 and Stata 15.0 software.

This study involved 11,645 postoperative cardiac surgery patients, including 8 case-control studies and 3 cohort studies, over which 18 risk factors were identified. The results of the meta-analysis indicated that statistically significant risk factors included age >65 years [odds ratios (OR) (95% CI ) = 3.47 (2.61-4.32)], female gender [OR (95%) = 1.54 (1.34-1.76)], combined heart valve and coronary artery bypass surgery [OR (95%) = 1.82 (1.23-2.70)], ejection fraction <40% [OR (95%) = 1.38 (1.17-1.63)], history of heart surgery [OR (95%) = 1.30 (1.06-1.59)], myocardial infarction [OR (95%) = 1.17 (1.05-1.31)], hyperlipidemia [OR (95%) = 0.76 (0.67-0.86)], hypertension [OR (95%) = 1.12 (1.03-1.22)], anticoagulant medication [OR (95%) = 0.77 (0.65-0.90)], cardiopulmonary bypass time >2 hours [OR (95%) = 20.26 (17.03-23.48)] and history of cardiopulmonary bypass [OR (95%) = 1.24 (1.09-1.41)].

Current evidence suggests that there are key risk factors for postoperative stress hyperglycemia in patients without diabetes who have undergone cardiac surgery. These factors can help identify patients at a high risk of perioperative stress hyperglycemia during cardiac surgery. This evidence provides a basis for healthcare professionals to develop predictive management strategies for perioperative stress hyperglycemia in patients without diabetes. However, more high-quality studies are required to address the limitations of the current research.

Patients with diabetic kidney disease (DKD) face an elevated risk of experiencing acute kidney injury (AKI), exacerbating the progression of DKD. This article offers a comprehensive review of the literature and knowledge of the primary pathophysiologic mechanisms underlying kidney damage, as well as the biological implications of maladaptive kidney repair in the context of DKD complicated by AKI. Additionally, we examine in detail the findings of clinical trials evaluating the efficacy and safety of intensive insulin treatment for hyperglycemic patients in intensive care units, alongside the potential risks of hypoglycemia and mortality. Furthermore, through critical analysis of clinical trial results, opportunities for personalized safety-based approaches to mitigate side effects are identified. It is imperative to conduct randomized-controlled studies to assess the impact of intensive insulin treatment on diabetic patients with DKD, and to validate AKI biomarkers in this patient population. Such studies will help to tailor treatment strategies to improve patient outcomes and preserve kidney function.

Dysglycaemia in hospitalised patients is associated with poorer clinical outcomes, including cardiovascular events, longer hospital stays, and increased risk of mortality. Therefore, glucose monitoring is necessary to achieve best outcomes.

This audit assesses use of point-of-care (POC) blood glucose (BG) testing in Tallaght University Hospital (TUH) over an 8-day period. It evaluates compliance with international and TUH glucose monitoring protocols and determines frequency of diabetes team consultations for inpatient adults.

Data from an 8-day period (12/03/2023-19/03/2023) were extracted from the TUH COBAS-IT system and analysed. Invalid tests were excluded. Hyperglycaemia was defined as ≥ 10 mmol/L and hypoglycaemia as ≤ 3.9 mmol/L. Persistent hyperglycaemia was defined as two BG results of ≥ 10 mmol/L. A chart review was conducted on adult patients with persistent hyperglycaemia to assess for HbA1C results, diabetes diagnosis, and diabetes consult.

3,530 valid tests were included and analysed. 674 individual patients had tests done. 1,165 tests (33.00%) were hyperglycaemic and 75 (2.12%) were hypoglycaemic. 68.25% of adults with persistent hyperglycaemia had an HbA1C test performed or documented within three months. 42.71% of inpatient adults with persistent hyperglycaemia and a known diabetes diagnosis received a consult from the diabetes team.

Increased adherence to hospital protocols for testing HbA1C in adults with persistent hyperglycaemia could improve treatment and clinical outcomes. Increased diabetes team consultation could facilitate appropriate treatment and improve patient outcomes in persistently hyperglycaemic adult patient populations.

Introduction: Glycemia is an important factor among critically ill patients in the intensive care unit (ICU). There is conflicting evidence on the preferred strategy of blood glucose control among patients with diabetes in the ICU. We aimed to conduct a meta-analysis comparing tight with liberal blood glucose in critically ill patients with diabetes in the ICU. Methods: We systematically searched PubMed, Embase, and Cochrane Central for randomized controlled trials (RCTs) comparing tight versus liberal blood glucose control in critically ill patients with diabetes from inception to December 2023. We pooled odds-ratios (OR) and 95% confidence intervals (CI) with a random-effects model for binary endpoints. We used the Review Manager 5.17 and R version 4.3.2 for statistical analyses. Risk of bias assessment was performed with the Cochrane tool for randomized trials (RoB2). Results: Eight RCTs with 4474 patients were included. There was no statistically significant difference in all-cause mortality (OR 1.11; 95% CI 0.95-1.28; P = .18; I² = 0%) between a tight and liberal blood glucose control. RoB2 identified all studies at low risk of bias and funnel plot suggested no evidence of publication bias. Conclusion: In patients with diabetes in the ICU, there was no statistically significant difference in all-cause mortality between a tight and liberal blood glucose control. PROSPERO registration: CRD42023485032.

This study evaluated the clinical utility of continuous glucose monitoring system (CGMS) in critically ill patients.

In this randomized controlled trial, we randomly assigned critically ill participants with diabetes or stress-induced hyperglycemia to the CGMS group (n = 48) or to the conventional point-of-care monitoring (POCM) group (n = 48). The glucose values and clinical outcome were compared between the two group. The primary endpoint was 28-day mortality after intensive care unit admission.

The 28-day mortality was not significantly different between the CGMS and POCM group (20.8% vs 31.3%, P = 0.25). The mean glucose, time-weighted average glucose, glucose standard deviation and time in range (3.9-10.0) were significantly improved in the CGMS group (all P < 0.05).

Compared with conventional POCM, CGMS did not decrease the 28-day mortality in critically ill participants with diabetes or stress-induced hyperglycemia. But CGMS may improve the glycemic control and may be increasingly used in critically ill patients.

The prognosis of patients with coronary artery disease is adversely affected by elevated fasting plasma glucose (FPG) levels. However, the relationship between FPG levels and in-hospital cardiac arrest (IHCA) remains unclear.

The objective of this study was to investigate the association between FPG levels and IHCA in patients diagnosed with acute coronary syndrome (ACS).

Data from a total of 31,726 ACS patients fitted with inclusion and exclusion criteria across 241 hospitals in the Improving Care for Cardiovascular Disease in China-ACS project from November 2014 to July 2019 were collected. Different logistic regression models were utilized to examine the associations of FPG levels with IHCA. Sensitivity analyses were then conducted to assess the robustness of the findings. Marginal effect analyses were also employed to evaluate the impact of different therapies.

A total of 335 cases of IHCA and 293 in-hospital mortality were recorded throughout the study. A non-linear relationship between FPG levels and IHCA was identified after adjusting for the covariates. Specifically, a significant association was found between elevated FPG levels (≥6.1 mmol/L) and an increased risk of IHCA. These findings remained consistent across different subgroup analyses including both the diabetic and non-diabetic patients. Additionally, the marginal effect analyses revealed that percutaneous coronary intervention could lower the high FPG-related risk.

The study findings showed a positive correlation between FPG levels and a higher incidence of IHCA, irrespective of the presence of diabetes.

Phosphate is a predominately intracellular anion that has several key roles in normal cellular functions. Derangements in serum phosphate concentration occur frequently during critical illness, particularly hypophosphataemia, which has been reported in up to 75% of Intensive Care Unit (ICU) patients. The association between hypophosphataemia and ICU outcomes reported in the literature are conflicting and and subject to substantial confounding. Exogenous phosphate can be administered in the ICU using the enteral and intravenous route safely. However, whether administering phosphate and correcting hypophosphataemia results in any patient-centred benefits, or harms, remains uncertain, particularly for patients with mild hypophosphataemia or low-normal phosphate levels. This review will highlight key aspects of hypophosphataemia management in the critically ill, summarise current best practice, and outline major research priorities.

Hyperglycaemia is common in intensive care unit (ICU) patients. Glycaemic monitoring and effective glycaemic control with insulin are crucial in the ICU to improve patient outcomes. However, glycaemic control and insulin use vary between ICU patients and hypo- and hyperglycaemia occurs. Therefore, we aim to provide contemporary data on glycaemic control and management, and associated outcomes, in adult ICU patients. We hypothesise that the occurrence of hypoglycaemia in acutely admitted ICU patients is lower than that of hyperglycaemia.

We will conduct a bi-centre cohort study of 300 acutely admitted adult ICU patients. Routine data will be collected retrospectively at baseline (ICU admission) and daily during ICU stay up to a maximum of 30 days. The primary outcome will be the number of patients with hypoglycaemia during their ICU stay. Secondary outcomes will be occurrence of severe hypoglycaemia, occurrence of hyperglycaemia, time below blood glucose target range, time above target range, all-cause mortality at Day 30, number of days alive without life support at Day 30 and number of days alive and out of hospital at Day 30. Process outcomes include the number of in-ICU days, glucose measurements (number of measurements and method) and use of insulin (including route of administration and dosage). All statistical analyses will be descriptive.

This cohort study will provide a contemporary overview of glucose evaluation and management practices in adult ICU patients and, thus, highlight potential areas for improvement through future clinical trials in this area.

Symptomatic intracranial hemorrhage (sICH) is a fatal complication after endovascular treatment (EVT) for acute large vessel occlusive (LVO) stroke. The aim of this study was to investigate the association between hyperglycemia and outcomes in patients with postprocedural sICH.

Of the 2567 patients with AIS who underwent EVT from two large multicenter randomized trials and two prospective multicenter registry studies, 324 patients occurred sICH with documented admission glucose were included in this study. The primary outcome was functional independence (defined as a modified Rankin Scale score of 0 to 2) at 90 days. Secondary outcomes included mRS score of 0 to 3, 0 to 1, and mRS score at 90 days. Safety outcome was the mortality within 90 days. Admission hyperglycemia was defined as a plasma blood glucose ≥7.8 mmol/L (140 mg/dL) in our analysis.

Of 324 eligible participants included in this study, hyperglycemia was observed in 130 (40.1%) patients. The median age was 67 (IQR, 58-75) years, and median blood glucose level was 7.1 (IQR, 6.0-9.3) mmol/L. After adjusting for confounding variables, admission hyperglycemia was associated with decreased odds of functional independence (adjusted odds ratio[OR] 0.34; 95% CI 0.17-0.68; P= 0.003), decreased odds of favorable outcome (adjusted OR 0.31; 95% CI 0.16-0.58; P < 0.001) and increased odds of mortality (adjusted OR 2.56; 95% CI 1.47-4.45; P = 0.001) at 90 days. After 1:1 propensity score matching analysis, the results were consistent with multivariable logistic regression analysis.

In patients who suffered sICH after EVT for acute large vessel occlusive stroke, hyperglycemia is a strong predictor of poor clinical outcome and mortality at 90 days.

This study was designed to compare individualized and conventional hyperglycemic thresholds for the risk of acute kidney injury (AKI) after cardiac surgery.

This was an observational study.

The study took place in a single-center tertiary teaching hospital.

Adult patients who underwent cardiac surgery between January 2012 and November 2021 were enrolled.

Two blood glucose thresholds were used to define intraoperative hyperglycemia. While the conventional hyperglycemic threshold (CHT) was 180 mg/dL in all patients, the individualized hyperglycemic threshold (IHT) was calculated based on the preoperative hemoglobin A1c level. Various metrics of intraoperative hyperglycemia were calculated using both thresholds: any hyperglycemic episode, duration of hyperglycemia, and area above the thresholds. Postoperative AKI associations were compared using receiver operating characteristic curves and logistic regression analysis. Among the 2,427 patients analyzed, 823 (33.9%) developed AKI. The C-statistics of IHT-defined metrics (0.58-0.59) were significantly higher than those of the CHT-defined metrics (all C-statistics, 0.54; all p < 0.001). The duration of hyperglycemia (adjusted odds ratio, 1.09; 95% confidence interval, 1.02-1.16) and area above the IHT (1.003; 1.001-1.004) were significantly associated with the risk of AKI, except for the presence of any hyperglycemic episode. None of the CHT-defined metrics were significantly associated with the risk of AKI.

Individually defined intraoperative hyperglycemia better predicted postcardiac surgery AKI than universally defined hyperglycemia. Intraoperative hyperglycemia was significantly associated with the risk of AKI only for the IHT. Target blood glucose levels in cardiac surgical patients may need to be individualized based on preoperative glycemic status.

Ebola virus disease (EVD) is associated with multisystem organ failure and high mortality. Severe hypoglycaemia is common, life-threatening, and correctable in critically ill patients, but glucose monitoring may be limited in EVD treatment units.

We conducted a retrospective review of patients admitted to EVD treatment units in Butembo and Katwa, Eastern DRC. Glucose measurements were done using a handheld glucometer at the bedside or using the Piccolo xpress Chemistry Analyzer on venous samples.

384 patients (median age 30 years (interquartile range, IQR, 20-45), 57% female) and 6422 glucose measurements (median 11 per patient, IQR 4-22) were included in the analysis. Severe hypoglycaemia (≤2.2 mmol/L) and hyperglycaemia (>10 mmol/L) were recorded at least once during the ETU admission in 97 (25%) and 225 (59%) patients, respectively. A total of 2004 infusions of glucose-containing intravenous solutions were administered to 302 patients (79%) with a median cumulative dose of 175g (IQR 100-411). The overall case fatality rate was 157/384 (41%) and was 2.2-fold higher (95% CI 1.3-3.8) in patients with severe hypoglycaemia than those without hypoglycaemia (p = 0.0042). In a multivariable Cox proportional hazards model, periods of severe hypoglycaemia (adjusted hazard ratio (aHR) 6.2, 95% CI 3.2-12, p < 0.0001) and moderate hypoglycaemia (aHR 3.0, 95% CI 1.9-4.8, p < 0.0001) were associated with elevated mortality.

Hypoglycaemia is common in EVD, requires repeated correction with intravenous dextrose solutions, and is associated with mortality.

Diabetes mellitus is currently approaching epidemic proportions and disproportionately affects patients in the hospital setting. In the United States, individuals living with diabetes represent over 17 million emergency department visits and 8 million admissions annually. The management of these patients in the hospital setting is complex and differs considerably from the outpatient setting. All patients with hyperglycemia should be screened for diabetes, as in-hospital hyperglycemia portends a greater risk for morbidity, mortality, admission to an intensive care unit, and increased hospital length of stay. However, the definition of hyperglycemia, glycemic targets, and strategies to manage hyperglycemia in the inpatient setting can vary greatly depending on the population considered. Moreover, the presenting illness, changing nutritional status, and concurrent hospital medications often necessitate thoughtful consideration to adjustments of home diabetes regimens and/or the initiation of new insulin doses. This review article will examine core concepts and emerging new literature surrounding inpatient diabetes management, including glycemic targets, insulin dosing strategies, noninsulin medications, new diabetes technologies, inpatient diabetes management teams, and discharge planning strategies, to optimize patient safety and satisfaction, clinical outcomes, and even hospital financial health.

Whether intensive glucose control reduces mortality in critically ill patients remains uncertain. Patient-level meta-analyses can provide more precise estimates of treatment effects than are currently available.

We pooled individual patient data from randomized trials investigating intensive glucose control in critically ill adults. The primary outcome was in-hospital mortality. Secondary outcomes included survival to 90 days and time to live cessation of treatment with vasopressors or inotropes, mechanical ventilation, and newly commenced renal replacement. Severe hypoglycemia was a safety outcome.

Of 38 eligible trials (n=29,537 participants), 20 (n=14,171 participants) provided individual patient data including in-hospital mortality status for 7059 and 7049 participants allocated to intensive and conventional glucose control, respectively. Of these 1930 (27.3%) and 1891 (26.8%) individuals assigned to intensive and conventional control, respectively, died (risk ratio, 1.02; 95% confidence interval [CI], 0.96 to 1.07; P=0.52; moderate certainty). There was no apparent heterogeneity of treatment effect on in-hospital mortality in any examined subgroups. Intensive glucose control increased the risk of severe hypoglycemia (risk ratio, 3.38; 95% CI, 2.99 to 3.83; P<0.0001).

Intensive glucose control was not associated with reduced mortality risk but increased the risk of severe hypoglycemia. We did not identify a subgroup of patients in whom intensive glucose control was beneficial.
