Factors associated with unexplained sudden deaths among adults aged 18-45 years in India - A multicentric matched case-control study.

BACKGROUND OBJECTIVES: In view of anecdotal reports of sudden unexplained deaths in India's apparently healthy young adults, linking to coronavirus disease 2019 (COVID-19) infection or vaccination, we determined the factors associated with such deaths in individuals aged 18-45 years through a multicentric matched case-control study. METHODS: This study was conducted through participation of 47 tertiary care hospitals across India. Cases were apparently healthy individuals aged 18-45 years without any known co-morbidity, who suddenly (<24 h of hospitalization or seen apparently healthy 24 h before death) died of unexplained causes during 1 st October 2021-31 st March 2023. Four controls were included per case matched for age, gender and neighborhood. We interviewed/perused records to collect data on COVID-19 vaccination/infection and post-COVID-19 conditions, family history of sudden death, smoking, recreational drug use, alcohol frequency and binge drinking and vigorous-intensity physical activity two days before death/interviews. We developed regression models considering COVID-19 vaccination ≤42 days before outcome, any vaccine received anytime and vaccine doses to compute an adjusted matched odds ratio (aOR) with 95 per cent confidence interval (CI). RESULTS: Seven hundred twenty nine cases and 2916 controls were included in the analysis. Receipt of at least one dose of COVID-19 vaccine lowered the odds [aOR (95% CI)] for unexplained sudden death [0.58 (0.37, 0.92)], whereas past COVID-19 hospitalization [3.8 (1.36, 10.61)], family history of sudden death [2.53 (1.52, 4.21)], binge drinking 48 h before death/interview [5.29 (2.57, 10.89)], use of recreational drug/substance [2.92 (1.1, 7.71)] and performing vigorous-intensity physical activity 48 h before death/interview [3.7 (1.36, 10.05)] were positively associated. Two doses lowered the odds of unexplained sudden death [0.51 (0.28, 0.91)], whereas single dose did not. INTERPRETATION CONCLUSIONS: COVID-19 vaccination did not increase the risk of unexplained sudden death among young adults in India. Past COVID-19 hospitalization, family history of sudden death and certain lifestyle behaviors increased the likelihood of unexplained sudden death.

Microbiological Pattern, Antimicrobial Resistance and Prevalence of MDR/XDR Organisms in Patients With Diabetic Foot Infection in an Indian Tertiary Care Hospital.

Foot infections are the most prevalent problem in persons with diabetes. The burden of multidrug resistant (MDR) microorganisms in diabetic foot infections (DFIs) is rising day by day. Given that, the present study aims to determine the variety of microorganisms isolated from the diabetic foot ulcers (DFUs), and their antibiotic sensitivity pattern. This prospective observational study was conducted for 1 year at Bharati Hospital and Research Centre, Pune, India. Clinically infected patients with DFU admitted to the surgery ward were included in this study. The specimen for microbiological studies is obtained from the wound swabs, soft tissue, and bone tissue as a part of routine clinical care. All demographic, clinical data, microbial culture results were collected, and evaluated for each case. Antimicrobial susceptibility testing to different agents was carried out using the VITEK-2® machine. A total of 110 microorganisms were isolated from 76 specimens, with an average of 1.4 organisms per lesion. Staphylococcus aureus (n = 27, 24.5%) and Escherichia coli (n = 17, 15.4%) were the most prevalent Gram-positive and Gram-negative organisms isolated, respectively. MDR organisms constituted up to 52 (47.2%), while 6 (5.4%) of the samples were extensively drug resistant (XDR). Methicillin-resistant S aureus (MRSA) accounted for up to 19 (70.3%) of the S aureus isolates, likewise extended-spectrum beta-lactamase producing microorganisms constituted 16 (14.5%) of total isolates in this study. Oxacillin and benzyl penicillin exhibited least susceptibility against Gram-positive bacteria, among Gram-negative organisms; cefuroxime, ceftriaxone, and ciprofloxacin were least sensitive. As most of the S aureus isolate in our study was MRSA, empirical antimicrobial therapy may include coverage for MRSA in a patient with risk factors associated with this pathogen. A crucial observation is the presence of XDR strains of Proteus mirabilis in DFIs, which is resistant to almost all the antimicrobials, tested. Appropriate antimicrobial selection may reduce the morbidity and the emergence of MDR organisms in DFIs.

Reversible Cardiomyopathy after Rituximab Treatment in a Chronic Lymphocytic Leukemia Patient.

INTRODUCTION: Rituximab is a monoclonal antibody that has shown efficacy in non-Hodgkin's lymphoma, chronic lymphocytic leukemia (CLL), both as a single agent and in combination with traditional chemotherapies. CASE REPORT: Here, we present a case wherein a 56-year-old man developed dilated cardiomyopathy following one cycle of rituximab and bendamustine chemotherapy protocol used to treat chronic lymphocytic leukemia. On the fifth day the patient developed hypotensive shock followed closely by the development of cough after two days. MANAGEMENT AND OUTCOME: The patient was started on carvedilol 3.125 mg, ramipril 2.5 mg, and torsemide 5 mg for treatment of cardiomyopathy. Blood transfusion was necessary for hypotensive shock. Antibiotic regimen was started for sepsis and progressive cough. The patient recovered fully from all the symptoms. DISCUSSION: This case illustrates the potential for cardiomyopathy with rituximab, particularly in patients with chronic lymphocytic leukemia, and its proposed mechanisms and treatment. The expanding utility of rituximab impels us to increase monitoring and awareness of this serious cardiovascular adverse effect.

Evaluation of antibiotic prescribing pattern in pediatrics in a tertiary care hospital.

BACKGROUND: The irrational use of antibiotics is a global issue and it can lead to morbidity, mortality, and increased health care costs. Hence, proper use of antibiotics is imperative and should be included in the pharmaceutical care plan. OBJECTIVE: The objective of this study was to evaluate the prescribing pattern of antibiotics for children using WHO core prescribing indicators. MATERIALS AND METHODS: A prospective, observational study was carried for 6 months in the pediatric department at a tertiary care hospital, Pune. The WHO prescribing indicators were used to evaluate the prescriptions, and the ideal WHO range was considered as a determining factor for rational prescription. RESULTS: A total of 302 patients were included in the study, with a mean patient age of 4.92 ± 4 years. The average number of drugs per encounter was 6.12 (WHO standard is less than 2). The percentage of antibiotics prescribed was 26.3% with an average of 1.63 antibiotics per prescription. Of the 493 antibiotics, 85.59% were injectable which is higher than the WHO standard of 13.4-24.1%. A near-optimal value of 99.59% antibiotics was prescribed from the hospital formulary which is similar to WHO standards, and the antibiotics prescribed with generic names were 25.76%. The most common class of antibiotics prescribed were cephalosporins and penicillins. CONCLUSION: Polypharmacy, high injectable use, and non-adherence to generic prescription were common in our tertiary care center. Continuous audits, training, and new treatment protocols are recommended.
