Abstract
Necrotizing fasciitis (NF) is a fatal disease with a high mortality rate that can be easily misdiagnosed. The aim of this study was to improve the diagnostic rate of NF and overall survival. We conducted a single-center, retrospective, noncontrolled study involving 36 patients who were admitted to our department between December 2017 and October 2019, and summarized the diagnostic key points and timing of surgical treatment. All patients were diagnosed at our department and underwent multiple courses of treatment. The records included information regarding underlying diseases, bacterial culture results, laboratory risk indicator for necrotizing fasciitis (LRINEC) score, number of procedures, and type of antibiotics. All 36 cases of NF were cured and showed good patient condition on follow-up; the mean number of surgeries was three, and the mean duration of hospitalization was 37 days (range, 21-83 days). The LRINEC scores of 16 patients were ≥8 points. Seventeen patients with underlying diabetic disease had higher inflammatory index scores than those without diabetes. The LRINEC scores of patients with (n = 17) and without (n = 19) DM were 7.40 ± 2.99 and 3.80 ± 2.39, respectively (P < .01). Cases of NF that were treated with early incision and surgical abscess drainage required fewer surgeries and a shorter length of hospitalization. Thus, surgeons should be more aware of NF and aim to make an early and accurate diagnosis using various approaches. Complete surgical debridement plays an essential role in NF treatment, and diabetes mellitus is a significant adverse factor that exacerbates the severity of NF. Negative-pressure techniques are useful in cases involving nonanaerobic infections and cause minimal complications.

Abstract
Sepsis remains a critical concern in healthcare, and its management is complicated when patients have pre-existing diabetes and varying body mass indexes (BMIs). This retrospective multicenter observational study, encompassing data from 15,884 sepsis patients admitted between 2012 and 2017, investigates the relationship between peak glucose levels and peak glycemic gap in the first 3 days of ICU admission, and their impact on mortality. The study reveals that maintaining peak glucose levels between 141-220 mg/dL is associated with improved survival rates in sepsis patients with diabetes. Conversely, peak glycemic gaps exceeding 146 mg/dL are linked to poorer survival outcomes. Patients with peak glycemic gaps below -73 mg/dL also experience inferior survival rates. In terms of predicting mortality, modified Sequential Organ Failure Assessment-Peak Glycemic Gap (mSOFA-pgg) scores outperform traditional SOFA scores by 6.8% for 90-day mortality in overweight patients. Similarly, the modified SOFA-Peak Glucose (mSOFA-pg) score demonstrates a 17.2% improvement over the SOFA score for predicting 28-day mortality in underweight patients. Importantly, both mSOFA-pg and mSOFA-pgg scores exhibit superior predictive power compared to traditional SOFA scores for patients at high nutritional risk. These findings underscore the importance of glycemic control in sepsis management and highlight the potential utility of the mSOFA-pg and mSOFA-pgg scores in predicting mortality risk, especially in patients with diabetes and varying nutritional statuses.

Abstract
Purposes This study aims to evaluate further differences between patients with diabetes and those without who have been diagnosed with necrotizing fasciitis (NF) to assist clinicians in improving morbidity and mortality. Methods All patients diagnosed with NF of an extremity were retrospectively reviewed and divided into two groups based on a diagnosis of diabetes. Patient charts were reviewed to obtain multiple variables, which were compared between groups. Results From 2015 to 2021, 115 patients underwent surgical intervention due to concern for NF of an extremity with 92 patients included for data computation. Patients with diabetes had an average Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score of 9.02 compared to 7.24 (p=0.02). Patients with diabetes had a significantly higher rate of undergoing amputation when diagnosed with NF (p<0.0001). The mortality rate for diabetes and non-diabetes cohorts were 30.9% and 18.9%, respectively (p=0.2). Conclusion This study demonstrated that patients with diabetes with confirmed NF of an extremity had a significantly higher LRINEC score were more likely to undergo an amputation primarily, and were more likely to have a polymicrobial infection compared to those without. The overall mortality rate of NF was 26.1%.

Abstract
CONTEXT Diabetes or hyperglycemia at admission are established risk factors for adverse outcomes during hospitalization for COVID-19, but the impact of prior glycemic control is not clear. OBJECTIVE We aimed to examine the associations between admission variables, including glycemic gap, and adverse clinical outcomes in patients hospitalized with COVID-19 infection. METHODS We examined the relationship between clinical predictors, including acute and chronic glycemia, and clinical outcomes, including intensive care unit (ICU) admission, mechanical ventilation (MV), and mortality among 1786 individuals with diabetes or hyperglycemia (glucose > 10 mmol/L twice in 24 hours) who were admitted from March 2020 through February 2021 with COVID-19 infection at 5 university hospitals in the eastern United States. RESULTS The cohort was 51.3% male, 53.3% White, 18.8% Black, 29.0% Hispanic, with age = 65.6 ± 14.4 years, BMI = 31.5 ± 7.9 kg/m2, glucose = 12.0 ± 7.5 mmol/L [216 ± 135 mg/dL], and HbA1c = 8.07% ± 2.25%. During hospitalization, 38.9% were admitted to the ICU, 22.9% received MV, and 10.6% died. Age (P < 0.001) and admission glucose (P = 0.014) but not HbA1c were associated with increased risk of mortality. Glycemic gap, defined as admission glucose minus estimated average glucose based on HbA1c, was a stronger predictor of mortality than either admission glucose or HbA1c alone (OR = 1.040 [95% CI: 1.019, 1.061] per mmol/L, P < 0.001). In an adjusted multivariable model, glycemic gap, age, BMI, and diabetic ketoacidosis on admission were associated with increased mortality, while higher estimated glomerular filtration rate (eGFR) and use of any diabetes medication were associated with lower mortality (P < 0.001). CONCLUSION Relative hyperglycemia, as measured by the admission glycemic gap, is an important marker of mortality risk in COVID-19.

Abstract
AIMS The aim was to report the prevalence of diabetes status in patients hospitalized with COVID-19 and assess the association between the glucometabolic status at admission and 90-day mortality. METHODS Consecutive patients hospitalized with COVID-19 were included in the study. All participants included had an HbA1c measurement 60 days prior to or within 7 days after admission. We studied the association between diabetes status, the glycemic gap (difference between admission and habitual status), admission plasma-glucose, and mortality using Cox proportional hazards regression. RESULTS Of 674 patients included, 114 (17%) had normal glucose level, 287 (43%) had pre-diabetes, 74 (11%) had new-onset, and 199 (30%) had diagnosed diabetes. No association between diabetes status, plasma-glucose at admission, and mortality was found. Compared to the 2nd quartile (reference) of glycemic-gap, those with the highest glycemic gap had increased mortality (3rd (HR 2.38 [1.29-4.38], p = 0.005) and 4th quartile (HR 2.48 [1.37-4.52], p = 0.002). CONCLUSION Abnormal glucose metabolism was highly prevalent among patients hospitalized with COVID-19. Diabetes status per se or admission plasma-glucose was not associated with a poorer outcome. However, a high glycemic gap was associated with increased risk of mortality, suggesting that, irrespective of diabetes status, glycemic stress serves as an important prognostic marker for mortality.

Abstract
CONTEXT Stress hyperglycemia has been studied in numerous critical illnesses for several decades. Despite the extensive accumulation of knowledge about this topic, the definition of stress hyperglycemia is not updated since 2007. SUBJECTS AND METHODS We performed a narrative review about stress hyperglycemia in acute myocardial infarction (AMI), aiming to improve its current definition and to give evidence supporting this. RESULTS The definition of stress hyperglycemia in 2021 we recommend is: "SH is a high ABGly in an AMI patient irrespective of DM status. It can be calculated as e.g., "stress hyperglycemia ratio" or "admission glucose delta"/"glycemic gap". This definition may serve to start a consensus document of the experts in the field. The evidence accumulates supporting the possibility to recognize stress hyperglycemia also in AMI patients with diabetes mellitus (DM) by calculating glycemia during the previous 2-3 months using glycated hemoglobin. Moreover, it is now obvious that 2007 definition of stress hyperglycemia did not take into account the necessity to separate cut-offs for the subgroups with vs. without DM. CONCLUSIONS We demonstrated the insufficiency of the current 2007 definition of stress hyperglycemia, provided evidence-based recommendation for the improvement and suggested the need for a consensus of the experts on this topic. In order to optimize the treatment of stress hyperglycemia in numerous critical illnesses, we ought to have its universal definition (as we already have the universal definition of AMI).

Abstract
(1) Background: Recent studies have reported that the glucose variability (GV), irrespective of glycosylated hemoglobin (HbA1c), could be an additional risk factor for the development of diabetic retinopathy (DR). However, measurements for GV, such as continuous glucose monitoring (CGM) and fasting plasma glucose (FPG) variability, are expensive and time consuming. (2) Methods: This present study aims to explore the correlation between the glycemic gap as a measurement of GV, and DR. In total, 2565 patients were included in this study. We evaluated the effect of the different types of glycemic gaps on DR progression. (3) Results: We found that the area under the curve (AUC) values of both the glycemic gap and negative glycemic gap showed an association with DR progression. (4) Conclusions: On eliminating the possible influences of chronic blood glucose controls, the results show that GV has deleterious effects that are associated with the progression of DR. The glycemic gap is a simple measurement of GV, and the predictive value of the negative glycemic gap in DR progression shows that GV and treatment-related hypoglycemia may cause the development of DR. Individual treatment goals with a reasonable HbA1c and minimal glucose fluctuations may help in preventing DR.

Abstract
Elevation of glucose level in response to acute coronary syndrome (ACS) has been recognized as stress induced hyperglycemia (SIH). Plenty of clinical studies have documented that SIH occurs very common in patients hospitalized with ACS, even in those without previously known diabetes mellitus. The association between elevated blood glucose levels with adverse outcome in the ACS setting is well-established. Yet, the precise definition of SIH in the context of ACS remains controversial, bringing confusions about clinical management strategy. Several randomized trials aimed to evaluate the effect of insulin-based therapy on outcomes of ACS patients failed to demonstrate a consistent benefit of intensive glucose control. Mechanisms underlying detrimental effects of SIH on patients with ACS are undetermined, oxidative stress might play an important role in the upstream pathways leading to subsequent harmful effects on cardiovascular system. This review aims to discuss various definitions of SIH and their values in predicting adverse outcome in the context of ACS, as well as the effect of intensive glucose control on clinical outcome. Finally, a glimpse of the underlying mechanisms is briefly discussed.

Abstract
Uncontrolled diabetes results in several metabolic alterations including hyperglycemia. Indeed, several preclinical and clinical studies have suggested that this condition may induce susceptibility and the development of more aggressive infectious diseases, especially those caused by some bacteria (including Chlamydophila pneumoniae, Haemophilus influenzae, and Streptococcus pneumoniae, among others) and viruses [such as coronavirus 2 (CoV2), Influenza A virus, Hepatitis B, etc.]. Although the precise mechanisms that link glycemia to the exacerbated infections remain elusive, hyperglycemia is known to induce a wide array of changes in the immune system activity, including alterations in: (i) the microenvironment of immune cells (e.g., pH, blood viscosity and other biochemical parameters); (ii) the supply of energy to infectious bacteria; (iii) the inflammatory response; and (iv) oxidative stress as a result of bacterial proliferative metabolism. Consistent with this evidence, some bacterial infections are typical (and/or have a worse prognosis) in patients with hypercaloric diets and a stressful lifestyle (conditions that promote hyperglycemic episodes). On this basis, the present review is particularly focused on: (i) the role of diabetes in the development of some bacterial and viral infections by analyzing preclinical and clinical findings; (ii) discussing the possible mechanisms by which hyperglycemia may increase the susceptibility for developing infections; and (iii) further understanding the impact of hyperglycemia on the immune system.

Abstract
Background Left ventricular systolic dysfunction (LVSD) occurs frequently after acute ST-segment elevation myocardial infarction (STEMI). The predisposing factors and underlying mechanism of post-infarct LVSD are not fully understood. The present study mainly investigated the correlation between glycaemic gap, a novel index of stress-induced hyperglycaemia (SIH), and post-infarct LVSD. Methods A total of 274 first STEMI patients were enrolled in this cross-sectional study. Transthoracic echocardiography was performed within 48 h after admission and at 6 months after discharge to obtain left ventricular ejection fraction (LVEF). The change in LVEF was calculated as LVEF at 6 months after discharge minus baseline LVEF. Additionally, post-infarct LVSD was defined as LVEF ≤ 50%. Most importantly, glycaemic gap was calculated as admission blood glucose (ABG) minus the estimated average glucose over the previous 3 months. Results In patients without diabetes mellitus (DM), multivariate linear regression analysis revealed that both glycaemic gap (Beta = − 1.214, 95% CI − 1.886 to − 0.541, p < 0.001) and ABG (Beta = − 1.124, 95% CI − 1.795 to − 0.453, p = 0.001) were associated with change in LVEF. In DM patients, only glycaemic gap was still associated with change in LVEF, although this association was not observed in univariate linear regression analysis. Regarding the association between SIH and post-infarct LVSD, multivariate logistic regression analysis revealed that both glycaemic gap (OR = 1.490, 95% CI 1.043 to 2.129, p = 0.028) and ABG (OR = 1.600, 95% CI 1.148 to 2.229, p = 0.005) were associated with an increased risk of having post-infarct LVSD in non-DM patients. However, after multivariate adjustment in DM patients, only glycaemic gap (OR = 1.399, 95% CI 1.021 to 1.919, p = 0.037) remained associated with an increased risk of having post-infarct LVSD. Furthermore, the predictive value of glycaemic gap for post-infarct LVSD was not inferior to ABG in non-DM patients (p = 0.499), and only glycaemic gap, instead of ABG, could significantly predict post-infarct LVSD in DM patients (AUC = 0.688, 95% CI 0.591 to 0.774, p = 0.002). Conclusions Glycaemic gap was strongly associated with a change in LVEF and an increased risk of having post-infarct LVSD in patients following STEMI. In STEMI patients with DM, glycaemic gap could provide more valuable information than ABG in identifying patients at high risk of developing post-infarct LVSD.

Abstract
BACKGROUND Necrotizing fasciitis (NF) is a devastating disease with substantial morbidity and mortality. Poor outcomes are attributed to delayed diagnosis and management. Tenwek Hospital, a teaching and referral center in rural Kenya, manages many cases despite variable resources. We aimed to understand the burden of NF. METHODS All patients with admission NF diagnosis who presented in 2017 were reviewed for demographics, investigations, treatment, and outcomes. The primary outcome was unfavorable outcome defined as in-hospital mortality or amputation. Secondary outcomes were discharge diagnosis of NF and cost. Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score was calculated. Logistic regression models were utilized to assess the impact of risk factors. RESULTS Sixty-seven patients were identified with an average age of 49.2 (±21) years. Medical comorbidities were present in 48% and history of trauma in 58%. Discharge diagnosis of NF occurred in 61% (N = 41). Overall, mortality occurred in 10% (N = 7) of patients with an initial NF diagnosis. At discharge, patients without NF had favorable outcomes in 96% (N = 25) compared to 78% (N = 32) with NF (p = 0.043). Final NF diagnosis costs 122,098 Kenyan Shillings more (95% confidence interval 36,142-208,054) than non-NF diagnosis (p value = 0.006). Factors associated with unfavorable outcome include diabetes mellitus, any comorbidity, increased heart rate, fever, hyperglycemia, anemia, and discharge NF diagnosis. Increased LRINEC score was associated with discharge NF diagnosis (p = 0.0006) and unfavorable outcome (p = 0.0157). CONCLUSIONS Patients with NF in rural Kenya experience delays to presentation, unfavorable outcomes, and substantial costs. Certain factors, including LRINEC score, help predict diagnosis and outcome.
