Background: Pregnant women experience physiological changes that make them more susceptible to respiratory infections, including COVID-19. Given the potential impact of COVID-19 on pregnancy, it is crucial to continue to investigate the effect of the pandemic on pregnant women and their infants. This information will be important for informing for all the stakeholders including clinical care, and public health policies. Method(s): This study is a retrospective observational analytical study conducted in the Department of Obstetrics and Gynecology at SMGS hospital, Jammu. The study included 180 pregnant females who reported to emergency Obstetrics and Gynecology from 1st April to 30 June 2020. The sample size of 180 patients was divided into two groups: Group 1 included 90 COVID-19 positive pregnant females and Group 2 included 90 COVID-19 negative pregnant females. Result(s): No significant differences were found in age, parity, gestational age, comorbidities, mode of delivery, maternal complications, neonatal Apgar scores, or birth weight. The prevalence of comorbidities and maternal complications was similar in both groups, and most neonates had normal Apgar scores and birth weights. Conclusion(s): Therefore, it is suggested that appropriate management and care should be provided to all pregnant women, regardless of their COVID-19 status, to minimize any potential adverse outcomes.Copyright © 2022, Anka Publishers.

Background: Severe acute respiratory syndrome coronavirus (SARSCoV- 2) is a novel virus that causes Coronavirus Disease 2019 (COVID- 19). High-throughput sequencing technologies such as whole genome sequencing (WGS) and sequencing of viral genome DNA are being implemented to identify and report on genetic factors that may influence variability in symptom severity and immune response among patients infected by SARS-CoV-2. Genome sequencing has been useful for clinical diagnostic purposes, and can reveal other useful information such as disease risk factors that might lead to disease prevention or patient management strategies. UsingWGS and bioinformatics software tools, we describe a novel pipeline for the analysis of medically relevant genetic results and other findings identified in COVID-19 positive individuals, and the generation of a genome report that can effectively communicate these results to patients and their physicians. Study design: Enrollment will include up to 1500 patients with a positive COVID-19 nasopharyngeal swab. Blood samples will be collected at baseline, 1 month, 6 months, and 1 year after diagnosis. Antibody isotype (IgG, IgA, and IgM), titers, and viral neutralization will be analyzed. DNA will be isolated from blood lymphocytes and host genomes will be sequenced. Whole genomes will be assessed using ACMG criteria for the interpretation of pathogenic sequence variation using in-house and third-party software tools, and publicly available disease and control databases. Comprehensive gene panels will be implemented to allow for patients to receive clinically significant findings, including risk factor and carrier status, from multiple categories of potential genetic conditions including blood and immunology, endocrine, metabolic/mitochondrial, musculoskeletal, hearing loss, neurology, cardiology, ophthalmology, renal, skin, and gastrointestinal disorders. Common disease risk will be assessed using polygenic risk scores calculated for 6 diseases (atrial fibrillation, coronary artery disease, type 2 diabetes, prostate cancer, colorectal cancer, breast cancer). Pharmacogenomic gene variants that alter metabolizer phenotype and drug response in individuals will be reported, in addition to patient HLA-type. The genomic predictions fromABO and Rh blood types will be summarized and reported. Largescale continental ancestry estimation will be performed using publicly available reference populations. Finally, using viral genome DNA sequencing, the SARS-CoV-2 viral lineage will be identified and reported. An appointment with the study genetic counsellor will be scheduled to discuss results identified in the genome report and manage appropriate clinical referrals if necessary. Serology results will be reported. Regression models will examine associations between antibody response (titer, antigen target, viral neutralization ability), physiological response (biochemical, hematological and clinical characteristics), patient outcomes, viral lineage and genomic results. Significance: This study will link clinically relevant genomic results, in addition to other biological and serological characteristics, to potential factors that contribute to variability in SARS-CoV-2 outcomes. Results will be shared with family physicians for clinical follow up. This study will establish an efficient workflow using highthroughput genomic sequencing technology coupled with emerging bioinformatics platforms for the generation of comprehensive genome reports to aid in COVID-19 patient management and follow-up.

BACKGROUND: Aerosol generation during temporal bone surgery caries the risk of viral transmission. Steps to mitigate this problem are of particular importance during the coronavirus disease 2019 pandemic. OBJECTIVE: To quantify the effect of barrier draping on particulate material dispersion during temporal bone surgery. METHODS: The study involved a cadaveric model in a simulated operating theatre environment. Particle density and particle count for particles sized 1-10 µ were measured in a simulated operating theatre environment while drilling on a cadaveric temporal bone. The effect of barrier draping to decrease dispersion was recorded and analysed. RESULTS: Barrier draping decreased counts of particles smaller than 5 µ by a factor of 80 in the operating theatre environment. Both particle density and particle count showed a statistically significant reduction with barrier draping (p = 0.027). CONCLUSION: Simple barrier drapes were effective in decreasing particle density and particle count in the operating theatre model and can prevent infection in operating theatre personnel.
