Symptoms 6 months following SARS-CoV-2 infection in Nepali women.

In Nepal, over 1 million individuals have tested positive for SARS-CoV-2. We sought to describe the frequency of nonrecovery from this infection at 6 months and associated symptoms. We conducted a retrospective cohort study of 6142 women who had positive and negative PCR tests for this infection 6 months previously at 3 institutions in Kathmandu. In telephone interviews women provided information on 22 symptoms and their intensities, health status and history, and functional status. Of 3732 women who had tested PCR positive, 630 (16.9%) reported that they were unrecovered. These 630 unrecovered women were distinguished statistically from the 3102 recovered women by more frequent histories of allergies, rheumatoid disease, BCG immunization, Covid vaccination, strep throat and recent URIs, and both weight gain and weight losses of more than 5 kg in the 6 months following testing, and stressful events in the preceding year. Fatigue, pain, difficulty remembering, shortness of breath, heat and cold intolerance and unrefreshing sleep were reported in 41.9% to 10.5% of these 630 unrecovered women. Six months after confirmed SARS-CoV-2 infection 16.9% of Nepali women have long-COVID manifested as an immune, metabolic, and hormonal systems disruptive and dysfunction syndrome.

Assessment of Antibiotic Resistance among Clinical Isolates of Enterobacteriaceae in Nepal.

Clinicians face a global challenge treating infections caused by Enterobacteriaceae because of the high rate of antibiotic resistance. This cross-sectional study from the Nepal Armed Police Force Hospital, Kathmandu, Nepal, characterized resistance patterns in Enterobacteriaceae across different antimicrobial classes and assessed incidences of multidrug-resistant (MDR) and extensively drug-resistant (XDR) infections. Enterobacteriaceae from clinical samples were isolated on blood and MacConkey agar, except for urine samples on cysteine lactose electrolyte-deficient agar. To determine antimicrobial susceptibility patterns, including MDR and XDR, the Kirby-Bauer disc diffusion method was used. Statistics were performed using SPSS, v. 17.0. Members of the family were identified in 14.5% (95% CI: 16.2-12.8%) of the total samples (N = 1,617), primarily in urine (54.7%, 128/234), blood (19.7%, 46/234), and sputum (15.0%, 35/234). Escherichia coli (n = 118, 44.2%) was the most predominant bacteria, followed by Citrobacter freundii (n = 81, 30.3%). As much as 95.6% (392/410) of the isolates were penicillin-resistant, whereas only 36.2% (290/801) were carbapenem-resistant. A total of 96 (36.0%) MDR and 98 (36.7%) XDR Enterobacteriaceae were identified. Proteus mirabilis (44.4%, 8/18) predominated MDR cultures, whereas C. freundii (53.1%, 43/81) predominated XDR cultures. Multidrug resistant (38.4%, 71/154) and XDR Enterobacteriaceae (22.7%, 35/154) were chiefly uropathogens. Fluoroquinolone resistance rates in non-MDR, MDR, and XDR isolates were 19.9%, 63.2%, and 96.2%, respectively, whereas cephalosporin resistance rates were 28.6%, 72.9%, and 95.4% and penicillin resistance rates were 67.0%, 97.4%, and 98.0%. One-seventh of patients visiting the hospital were found to be infected with Enterobacteriaceae, and of these patients, at least one-fourth were infected with MDR strains.

Assessment of four in vitro phenotypic biofilm detection methods in relation to antimicrobial resistance in aerobic clinical bacterial isolates.

INTRODUCTION: The lack of standardized methods for detecting biofilms continues to pose a challenge to microbiological diagnostics since biofilm-mediated infections induce persistent and recurrent infections in humans that often defy treatment with common antibiotics. This study aimed to evaluate diagnostic parameters of four in vitro phenotypic biofilm detection assays in relation to antimicrobial resistance in aerobic clinical bacterial isolates. METHODS: In this cross-sectional study, bacterial strains from clinical samples were isolated and identified following the standard microbiological guidelines. The antibiotic resistance profile was assessed through the Kirby-Bauer disc diffusion method. Biofilm formation was detected by gold standard tissue culture plate method (TCPM), tube method (TM), Congo red agar (CRA), and modified Congo red agar (MCRA). Statistical analyses were performed using SPSS version 17.0, with a significant association considered at p<0.05. RESULT: Among the total isolates (n = 226), TCPM detected 140 (61.95%) biofilm producers, with CoNS (9/9) (p<0.001) as the predominant biofilm former. When compared to TCPM, TM (n = 119) (p<0.001) showed 90.8% sensitivity and 70.1% specificity, CRA (n = 88) (p = 0.123) showed 68.2% sensitivity and 42% specificity, and MCRA (n = 86) (p = 0.442) showed 65.1% sensitivity and 40% specificity. Juxtaposed to CRA, colonies formed on MCRA developed more intense black pigmentation from 24 to 96 hours. There were 77 multi-drug-resistant (MDR)-biofilm formers and 39 extensively drug-resistant (XDR)-biofilm formers, with 100% resistance to ampicillin and ceftazidime, respectively. CONCLUSION: It is suggested that TM be used for biofilm detection, after TCPM. Unlike MCRA, black pigmentation in colonies formed on CRA declined with time. MDR- and XDR-biofilm formers were frequent among the clinical isolates.

Analysis of altered level of blood-based biomarkers in prognosis of COVID-19 patients.

INTRODUCTION: Immune and inflammatory responses developed by the patients with Coronavirus Disease 2019 (COVID-19) during rapid disease progression result in an altered level of biomarkers. Therefore, this study aimed to analyze levels of blood-based biomarkers that are significantly altered in patients with COVID-19. METHODS: A cross-sectional study was conducted among COVID-19 diagnosed patients admitted to the tertiary care hospital. Several biomarkers-biochemical, hematological, inflammatory, cardiac, and coagulatory-were analyzed and subsequently tested for statistical significance at P<0.01 by using SPSS version 17.0. RESULTS: A total of 1,780 samples were analyzed from 1,232 COVID-19 patients (median age 45 years [IQR 33-57]; 788 [63.96%] male). The COVID-19 patients had significantly (99% Confidence Interval, P<0.01) elevated levels of glucose, urea, alanine transaminase (ALT), aspartate aminotransaminase (AST), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), white blood cell (WBC), C-reactive protein (CRP), procalcitonin (PCT), interleukin-6 (IL-6), ferritin, D-Dimer, and creatinine phosphokinase-MB (CPK-MB) compared to the control group. However, the levels of total protein, albumin, and platelets were significantly (P<0.01) lowered in COVID-19 patients compared to the control group. The elevated levels of glucose, urea, WBC, CRP, D-Dimer, and LDH were significantly (P<0.01) associated with in-hospital mortality in COVID-19 patients. CONCLUSIONS: Assessing and monitoring the elevated levels of glucose, urea, ALT, AST, ALP, WBC, CRP, PCT, IL-6, ferritin, LDH, D-Dimer, and CPK-MB and the lowered levels of total protein, albumin, and platelet could provide a basis for evaluation of improved prognosis and effective treatment in patients with COVID-19.

Keywords: cytology; histology; human papillomavirus; Nepal; prevalence.

Co-infection of Uropathogenic Escherichia coli among COVID-19 Patients Admitted to a Tertiary Care Centre: A Descriptive Cross-sectional Study.

Introduction: Simultaneous infection of antibiotic-resistant uropathogens in patients with COVID-19 has necessitated the revision of the prescription of broad-spectrum antibiotics on the grounds of evidence-based studies and antimicrobial stewardship principles. The objective of this study was to find out the prevalence of uropathogenic Escherichia coli co-infection among hospital-admitted COVID-19 patients of a tertiary care centre. Methods: This descriptive cross-sectional study was conducted in urinary tract infection suspected COVID-19 patients admitted to a tertiary care hospital, from 25th June to 24th December 2021 after ethical clearance from the Institutional Review Committee with registration number 207707860. Convenience sampling was used. Serum procalcitonin levels were also measured. Data analysis was performed using the Statistical Package for the Social Sciences software version 17.0. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data, and mean and standard deviation for continuous data. Results: Among the 49 hospital-admitted COVID-19 patients, 3 (6.12%) (0.59-12.83 at 95% Confidence Interval) were co-infected with uropathogenic Escherichia coli. Absolute non-susceptibility of Escherichia coli to antibiotics such as ceftriaxone, cotrimoxazole, nalidixic acid, gentamicin, and ampicillin was observed. All isolates were multidrug-resistant. All co-infected patients were female and had a median age of 35 years. Mean±SD value for procalcitonin in patients with co-infection (6.13±7.88 ng/ml) was six times higher than for the patients without co-infection (0.95±1.11 ng/ml). Conclusions: Escherichia coli co-infection in hospitalised COVID-19 patients was less frequent as compared to published literature. The serum procalcitonin value in patients with co-infection was substantially higher than that of patients without co-infection. Keywords: antimicrobial drug resistance; co-infection; COVID-19; Escherichia coli; procalcitonin.

Stress Fractures among Paramilitary Trainee Visiting a Paramilitary Hospital of Nepal: A Descriptive Cross-sectional Study.

INTRODUCTION: Young paramilitary recruits, who undergo strenuous exercise during basic training, are often presented with stress fractures, which could be due to an inadequate vitamin D (25-hydroxyvitamin D) intake. This study aimed to find the prevalence of stress fracture among young paramilitary trainees visiting the orthopedic outpatient department of a paramilitary hospital. METHODS: This was a descriptive cross-sectional study done among paramilitary trainees in a paramilitary Hospital of Nepal between April 2019 to April 2021. The study was approved by the Ethical Review Board (Reference number: 1003) of the Nepal Health Research Council. Convenience sampling was used. Anthropometric variables, serum 25-hydroxyvitamin D level, and bone mineral density of spine and hip were determined. Data analysis was performed using the Statistical Package for the Social Sciences software version 17.0. Point estimate at 95% Confidence Interval was calculated along with frequency, proportion for binary data and mean, standard deviation for continuous data. RESULTS: Among 417 young paramilitary trainees, 24 (5.76%) (3.52-7.99 at 95% Confidence Interval) were found to have a stress fracture. The stress fracture patients had a serum 25-hydroxyvitamin D level of 21.47ng/mL±6.98. Similarly, the bone mineral density value of the spine and hip among the patients was -1.34g/cm2±1.37 and 0.36g/cm2±1.24, respectively. CONCLUSIONS: The prevalence of stress fracture among young paramilitary trainee was high compared to previous studies. Additionally, average Vitamin D and the bone mineral density value of the spine and the total hip among stressed fractured patients were also low.

Role of Tocilizumab in the Treatment of COVID-19 Patients with Cytokine Storm: A Case Series.

The in-hospital mortality in patients with COVID-19 could be correlated with severe acute respiratory syndrome coronavirus-2 induced hyper-inflammation, which is attributed to an unconstrained inflammatory cytokine storm. The pro-inflammatory cytokine, specifically, interleukin-6 plays a prominent role in the cytokine storm and may result in alveolar-capillary blood-gas exchange dysfunction. Therefore, the method to block the signal transduction pathway of interleukin-6 could be a potential treatment for severe COVID-19 patients. In this case series of three patients with severe COVID-19, we focus on the rationale for utilization of tocilizumab, an anti-interleukin-6 receptor antibody, which could block the signal transduction pathway of interleukin-6. The observations from this study allowed us to hypothesize that the infusions of tocilizumab may not reduce the elevated level of interleukin-6, and hence may not be a significant therapeutic for reducing in-hospital mortality associated with COVID-19. Additionally, it could also be speculated that interleukin-6 may not be a potentially actionable target cytokine to treat COVID-19-associated cytokine storms.
