Predictors Associated with In-hospital Mortality among COVID-19 Patients during the Second Wave in a Tertiary Care Hospital, Gujarat, India: A Retrospective Observational Study.

BACKGROUND: Fatalities due to coronavirus disease 2019 (COVID-19) have already crossed to more than 5 million globally so far. Hence, it is crucial for us to identify the risk factors associated with hospital deaths starting from first contact which can help to give timely treatment to the targeted population. OBJECTIVES: This retrospective cohort study was conducted to identify various factors related to in-hospital mortality related to COVID-19 in our region. MATERIALS AND METHODS: The present study was a single-center, retrospective cohort study of 675 adult patients, admitted with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection between 1st April and 25th May 2021 in our tertiary care hospital. Baseline demographic profile, comorbidities, clinical characteristics, and investigatory findings were analyzed for increased odds of mortality. RESULTS: A total of 181 (26.8%) patients died and 494 (73.2%) survived. There were 65.4% of males and no difference was found between genders in terms of mortality. Comorbidities associated with in-hospital death in our cohort were age group ≥50 years (p<0.001), diabetes (p<0.0007), and renal injury (p<0.0001). More than half of the patients died during the first week of admission. Breathlessness (83%) was the most common symptom in non-survivors. Neutrophil-to-lymphocyte ratio (NLR), S. creatinine, D-dimer, ferritin, and C-reactive protein (CRP) were increased significantly among the patients who died. Multivariate logistic regression revealed age ≥50 years [adjusted odds ratio (AOR) 2.30, 95% confidence interval (CI) 1.45-3.64] and oxygen (O2) saturation <94% at the time of admission (AOR 2.62, 95% CI 1.75-3.93) were associated with mortality. CONCLUSION: Overall in-hospital mortality was 26.8%. Higher age and low O2 saturation were the major risk factors associated with in-hospital mortality.

Cardiovascular risk reduction intervention among school-students in Kolkata, West Bengal - the CRRIS study protocol.

BACKGROUND: Increasing burden of cardiovascular risk-factors among adolescent school-children is a major concern in India. Dearth of information regarding the burden of these factors and the efficacy of educational intervention in minimizing them among urban school-students of India called for a school-based, educational intervention involving a representative sample of these students and their caregivers. METHODOLOGY: Using a randomized-controlled design with stratified-random sampling, 1000 students (approximately 50/school) of 9th grade from 20 randomly selected schools (representing all socio-economic classes and school-types) and their caregivers (preferably mothers) will be recruited. Objectives of the study will include: estimation of the baseline burden and post-interventional change in cardiovascular risk-factors, related knowledge, perception and practice among participants in Kolkata. DATA COLLECTION: After obtaining appropriate consent (assent for adolescents), collection of the questionnaire-based data (regarding cardiovascular disease/risk-factor related knowledge, perception, practice), anthropometric measurements, stress assessment and cardiological check-up (pulse and blood pressure measurement along with auscultation for any abnormal heart sounds) will be conducted for each participating students twice at an interval of six months. In between 6 educational sessions will be administered in 10 of the 20 schools randomized to the intervention arm. After the follow-up data collection, same sessions will be conducted in the non-interventional schools. DATA ANALYSES AND DELIVERABLE: Descriptive and inferential analyses (using SAS 9.3) will be conducted to determine the distribution of the risk-factors and efficacy of the intervention in minimizing them so that policy-making can be guided appropriately to keep the adolescents healthy in their future life.

A novel use of EP catheter in extraction of trapped intracardiac devices: Two case reports.

The decision to retrieve chronically implanted abandoned leads and trapped intracardiac devices percutaneously has been difficult and highly controversial. We present two case reports in which electrophysiological ablation catheter was used to retrieve infected abandoned pacemaker lead and trapped permacatheter (permacath) in right ventricle. We could avert major cardiovascular surgeries in both the patients by simply modifying the traditionally used techniques for extraction of intracardiac devices.

Cardiovascular health among healthy population of Northeast region of India: a cross-sectional study comparing urban-tribal difference.

Cardiovascular disease is the leading cause of adult mortality in India but data on the prevalence of cardiovascular risk factors are scarce, especially from North-east region of India. This study aims to assess the prevalence and the urban/tribal gradient of cardiovascular disease risk factors among healthy population of Tripura. A cross-sectional study was carried out among 238 healthy individuals (140 urban and 98 tribal) in one urban and five tribal areas of Tripura. Data was collected on sociodemographic profile, medical history, anthropometry, dietary patterns and addiction. Fasting blood samples were collected for biochemical analysis. Prevalence of cardiovascular disease risk factors and short-term cardiovascular disease risk score was calculated. The association of independent variables with 10-year cardiovascular disease risk score were examined by using multiple regression model. Prevalence of obesity, hypertension, diabetes, dyslipidaemia, metabolic syndrome and short-term cardiovascular disease risk score were higher in urban group. Urban people had higher salt, calories and fat intake. No difference was found in the addiction patterns of tobacco and alcohol but frequency and quantity being higher in tribal area. Dyslipidaemia and alcohol consumption showed significant positive association with 10-year cardiovascular disease risk score in both groups. While the non-sedentary lifestyle and dietary habits (low salt, low fat, carbohydrate predominant) of tribal population need to be promoted as a whole across the nation, they need to be protected from the adverse effects of rampant prevalence of tobacco and alcohol addiction among them. Urban population need to be extricated from adverse effects of sedentary lifestyle, modern food habits (high salt, high fat) and tobacco-alcohol addiction.

Presentation and complications among the malaria death cases from municipal corporation hospitals & civil hospital of Ahmedabad during the year 2007.

The present study was carried out to have understanding of characterisation including symptoms, signs and laboratory parameters which are associated with fatality of malaria cases on arrival to hospital which may lead to early recognition and improved management. Information about deaths due to Malaria, as reported to malaria Department of Ahmedabad Municipal Corporation by municipal corporation hospitals and civil hospital from January 07 to December 07, was used to locate details of those deaths in respective hospitals by obtaining indoor case papers and death reports of those cases from Medical Record Section of respective hospitals and were analyzed by using appropriate statistical software. Total 57 malaria deaths occurred in the above mentioned 4 hospitals. Overall Case Fatality Rate was 3.03% for indoor malaria cases. Complete information could be obtained about 42 cases. Mean age of cases was 36.50 years. 45.23% of patients falling in the age group > = 40 yrs. There were 57.1% males and 42.9% females. 55 cases were positive for P. falciparum, 1 case for P. vivax and 1 case was having mixed infection. Average duration of Hospital stay was 2.87 days and average total duration of illness was 6.82 days. The most common presenting symptom was intermittent fever with vomiting & altered sensorium in 38.88% & most common complication was Acute Renal Failure in 45.2% of cases. Paired t-test was applied on the investigations carried out on the day of admission and those carried out on the day or before a day of death and found significant for the levels of Haemoglobin, Blood Urea & Serum Billirubin. Malaria still remains one of the important causes of admission and mortality. In view of changes in anti-malarial drug policy and introduction of costly artemisinin combination therapy accurate, rapid diagnostic tools are necessary to target treatment to people in need.
