ABSTRACT
SARS CoV-2 is a ?-coronavirus responsible for the current COVID-19 pandemic. Although there is increase severity and mortality described in the elderly population and people with co-morbidities, all age groups are susceptible to COVID-19. Recent data showed that obesity has also emerged as a significant risk factor for COVID-19 mortality. As per the WHO, most of the world's population lives in countries where obesity is highly prevalent. In this context, we aimed to review various studies that showed obesity as an independent risk factor for mortality in SARS CoV-2 infection. We followed the PRISMA guidelines to search for two databases including PubMed and Google Scholar using the key terms “COVID-19, OBES* and MORTALITY,” SARS CoV-2, OBES* and MORTALITY” “COVID-19, OBESITY, and MORTALITY,” SARS Cov-2, OBESITY and MORTALITY,” respectively, up to August 3, 2020. Twelve studies were finally included in this review after applying inclusion and exclusion criteria. All 12 studies included in the review consistently showed that obesity is a risk factor for mortality in patients with SARS CoV-2 infection. These studies have also shown evidence that obesity leads to increased hospitalization, ICU admission, increased need for mechanical ventilation, and poor prognosis among patients with SARS CoV-2 infection. Obesity is an independent risk factor for mortality in patients infected with this novel coronavirus. Appropriate triage, monitoring, and vigilance are required while dealing with individuals with obesity with SARS CoV2 infection, especially in the young obese population. More epidemiological studies need to be done taking BMI also into consideration in COVID-19 patients to find the exact cause of increased severity and mortality and develop appropriate preventive and therapeutic strategies.
ABSTRACT
Title: Lower respiratory tract infections in intensive care units. A four year study from North India. Study Design: Prospective study Place and Duration of Study: Sher-i-Kashmir Institute of Medical Sciences, Srinagar Kashmir. Four years (July 2010 and June 2014). Methodology: A prospective analysis of respiratory specimens from various intensive care units (ICUs) was done over a period of four years. Antimicrobial susceptibility of culture positive isolates to various antibiotics was performed as per Clinical Laboratory Standards Institute (CLSI) guidelines. Gram-negative bacteria (GNB) were screened for extended spectrum β-lactamase (ESBL) and metallo-β-lactamase (MBL) production; whereas methicillin and vancomycin resistance was searched in staphylococci and enterococci isolates respectively. Results: The frequencies of Gram-positive and Gram-negative bacteria were 26% and 68% respectively with yeast recovered in 8% of the specimens. K. pneumoniae and Acinetobacter spp were the most common Gram-negative bacteria and S. aureus the most common Gram-positive one. High level resistance to all the antimicrobials was seen; with K. pneumoniae being the most multidrug resistant GNB isolated in the ICU setting. ESBL production was also highest in K. pneumoniae isolates (67.1%). Also 59.6% of Acinetobacter isolates were found to be MBL producers. Methicillin resistance was seen in 48% of S. aureus and 85.5% of coagulase negative staphylococci (CoNS) isolates with vancomycin resistance seen in 6.7% of enterococcal isolates. Conclusion: An increasing trend over the years in the antibiotic resistance of respiratory pathogens in ICUs of this north Indian state was seen that calls for urgent measures to limit their continued rise.
ABSTRACT
Background & objectives: Community outbreaks of disease amongst nomadic populations generally remain undocumented. Following a reported increase in acute respiratory tract infections (ARI) in May 2011 in a nomadic population of Sangerwini in Jammu & Kashmir, India, we examined the patients with ARI symptoms and their nasal swabs were tested for influenza virus. Methods: Patients with ARI (n=526) were screened from May 14 to 23, 2011 and nasopharyngeal swabs collected from 84 with Influenza like illness (ILI) for bacterial cultures and influenza virus testing. Samples were tested for influenza A and influenza B by real time (RT)-PCR. Results: Twelve (14.3%) of the 84 patients tested positive for influenza B, compared to only one (0.9%) of 108 patients with ILI in a parallel survey performed in Srinagar during the same period, suggesting a localized outbreak in the isolated nomadic community. All presented with respiratory symptoms of less than seven days. Familial clustering was seen in 40 per cent (25% of influenza B positives). Average daytime temperatures ranged from 15-16oC compared to 22oC in Srinagar. Four patients developed pneumonia whereas others ran a mild course with a total recovery with oseltamivir and symptomatic therapy. Interpretation & conclusion: Our report of confirmed influenza B in this underprivileged nomadic population argues for routine surveillance with efforts to improve vaccination and infection control practices.
ABSTRACT
BACKGROUND: Pleural effusion (PF) is a common clinical presentation in several diseases. Various parameters from pleural fluid have been studied to identify the cause. The diagnostic value of these parameters varies. The present study was carried out to evaluate the value of alkaline phosphatase concentration in the pleural effusions as a diagnostic tool. METHODS: One hundred and one patients with pleural effusion admitted over a period of two years were studied. The diagnosis was confirmed by pleural biopsy and cytology for malignant cells. RESULTS: Pleural fluid alkaline phosphatase levels of more than 75 mg/dl was found in exudative effusions and less than 75 mg/dl in transudative ones. But it did not differentiate tubercular pleural effusions from other exudative ones. CONCLUSION: Pleural fluid alkaline phosphatase of >75 mg/dl is a useful biochemical marker to suggest exudative effusions.
