Objectives: This study evaluated the incidence and risk factors for deep venous thrombosis (DVT) while on thromboprophylaxis, in patients admitted to the medical intensive care unit (MICU), and to assess its impact on outcomes. Methods: Consecutive patients admitted to the MICU underwent compression ultrasound of the jugular, axillary, femoral, and popliteal veins at admission, day 3 and 7 to screen for DVT. All patients were on pharmacological and/or mechanical thromboprophylaxis as per protocol. The primary outcome was the incidence of DVT (defined as occurrence on day 3 or 7). Secondary outcomes were death and duration of hospitalization. Risk factors for DVT were explored using bivariate and multivariable logistic regression analysis and expressed as risk ratio (RR) with 95% confidence intervals (CIs). Results: The incidence of DVT was 17.2% (95% CI 12.0, 22.3) (n = 35/203); two-thirds were catheter associated (23/35). There was no difference in mortality between those with and without incident DVT (9/35 vs 40/168, p = 0.81). The mean (SD) duration of hospitalization was longer in the DVT group (20.1 (17) vs 12.9 (8.5) days, p = 0.007). Although day 3 INR (RR 2.1, 95% CI 0.9-5.3), age >40 years (2.1, 0.8-5.3), vasopressor use (1.0, 0.4-2.9) and SOFA score (0.9, 0.85-1.1) were associated with the development of DVT on bivariate analysis, only central venous catheters (15.97, 1.9-135.8) was independently associated with DVT on multivariable analysis. Conclusions: Despite thromboprophylaxis, 17% of ICU patients develop DVT. The central venous catheter is the main risk factor. DVT is not associated with increased mortality in the setting of prophylaxis. [ABSTRACT FROM AUTHOR]

Introduction: The objective of this study was to examine the evolution of carbapenem-resistant Klebsiella pneumoniae (CRKp) infections and their impact at a tertiary care hospital in South India. Methods: A comparative analysis of clinical data from two prospective cohorts of patients with CRKp bacteremia (C1, 2014–2015; C2, 2021–2022) was carried out. Antimicrobial susceptibilities and whole genome sequencing (WGS) data of selected isolates were also analyzed. Results: A total of 181 patients were enrolled in the study, 56 from C1 and 125 from C2. CRKp bacteremia shifted from critically ill patients with neutropenia to others (ICU stay: C1, 73%; C2, 54%; p = 0.02). The overall mortality rate was 50% and the introduction of ceftazidime-avibactam did not change mortality significantly (54% versus 48%; p = 0.49). Oxacillinases (OXA) 232 and 181 were the most common mechanisms of resistance. WGS showed the introduction of New Delhi metallo-β-lactamase-5 (NDM-5), higher genetic diversity, accessory genome content, and plasmid burden, as well as increased convergence of hypervirulence and carbapenem resistance in C2. Conclusions: CRKp continues to pose a significant clinical threat, despite the introduction of new antibiotics. The study highlights the evolution of resistance and virulence in this pathogen and the impact on patient outcomes in South India, providing valuable information for clinicians and researchers.

Background: Recent cohort studies have proven the association between sleep deprivation and adverse glycemic control (GC). The aim of this study was to assess the prevalence of excessive daytime sleepiness (EDS), a subjective measure of sleep deprivation, among type 2 diabetic mellitus (T2DM) patients and its association with GC. Methods: This cross‐sectional study was conducted between July 2015 and June 2016 in five diabetes clinics in the district of Erode, Tamil Nadu, India. An equal number of consenting patients with T2DM was recruited consecutively from each of the centers, and EDS was measured subjectively using the Epworth sleepiness scale (ESS), whereas GC was assessed using HbA1c levels. Results: In all, 126 patients were screened and 102 were found eligible for the study. The prevalence of EDS was 17.5% (95% confidence interval 10.13–24.87). The association between ESS scores and HbA1c levels was analyzed using linear regression after adjusting for age, dietary intake, inflammatory markers (erythrocyte sedimentation rate), depression (Patient Health Questionnaire‐9 score) and stress (Perceived Stress Scale score): for every unit increase in the ESS score, HbA1c increased by 0.143 g/dL (P < 0.001). Conclusion: Subjective EDS was seen in approximately one‐quarter of patients with diabetes in our population. There was a positive association between EDS and glycemic control. Screening of patients with diabetes for EDS should be part of routine diabetes management. HighlightsThe prevalence of excessive daytime sleepiness (EDS) among patients diagnosed with type 2 diabetes mellitus in an urban south Indian population is 17.5%.There is a significant positive correlation between EDS and glycemic control, as measured by HbA1c.
