Pre- and post-COVID-19 antimicrobial resistance profile of bacterial pathogens, a comparative study in a tertiary hospital.

INTRODUCTION: Antimicrobial resistance (AMR) is a natural evolutionary process in bacteria that is accelerated by selection pressure from the frequent and irrational use of antimicrobial drugs. This study aimed to determine the variations in AMR patterns of priority bacterial pathogens at a tertiary care hospital in the Gaza Strip during pre- and post-COVID-19 pandemic. METHODOLOGY: This is a retrospective observational study to determine the AMR patterns of bacterial pathogens at a tertiary hospital in the Gaza Strip in the post-COVID-19 pandemic period compared to the pre-COVID-19 period. Positive-bacterial culture data of 2039 samples from pre-COVID-19 period and 1827 samples from post-COVID-19 period were obtained from microbiology laboratory records. These data were analysed and compared by Chi square test using Statistical Package for Social Sciences (SPSS) Program. RESULTS: Gram-positive and Gram-negative bacterial pathogens were isolated. Escherichia coli was the most prevalent in both study periods. The overall AMR rate was high. There was a statistically significant increase in resistance to cloxacillin, erythromycin, cephalexin, co-trimoxazole and amoxicillin/clavulanic acid in the post-COVID-19 period compared to pre-COVID-19 period. There was also a significant decrease in resistance to cefuroxime, cefotaxime, gentamicin, doxycycline, rifampicin, vancomycin and meropenem in the post-COVID-19 period. CONCLUSIONS: During the COVID-19 pandemic, the AMR rates of restricted and noncommunity-used antimicrobials declined. However, there was an increase in AMR to antimicrobials used without medical prescription. Therefore, restriction on the sale of antimicrobial drugs by community pharmacies without a prescription, hospital antimicrobial stewardship and awareness about the dangers of extensive use of antibiotics are recommended.

Risk Factors in HIV-1 Positive Patients on the Intensive Care Unit: A Single Center Experience from a Tertiary Care Hospital.

HIV-positive patients with acquired immunodeficiency syndrome (AIDS) often require treatment on intensive care units (ICUs). We aimed to present data from a German, low-incidence region cohort, and subsequently evaluate factors measured during the first 24 h of ICU stay to predict short- and long-term survival, and compare with data from high-incidence regions. We documented 62 patient courses between 2009 and 2019, treated on a non-operative ICU of a tertiary care hospital, mostly due to respiratory deterioration and co-infections. Of these, 54 patients required ventilatory support within the first 24 h with either nasal cannula/mask (n = 12), non-invasive ventilation (n = 16), or invasive ventilation (n = 26). Overall survival at day 30 was 77.4%. While ventilatory parameters (all p < 0.05), pH level (c/o 7.31, p = 0.001), and platelet count (c/o 164,000/µL, p = 0.002) were significant univariate predictors of 30-day and 60-day survival, different ICU scoring systems, such as SOFA score, APACHE II, and SAPS 2 predicted overall survival (all p < 0.001). Next to the presence or history of solid neoplasia (p = 0.026), platelet count (HR 6.7 for <164,000/µL, p = 0.020) and pH level (HR 5.8 for <7.31, p = 0.009) remained independently associated with 30-day and 60-day survival in multivariable Cox regression. However, ventilation parameters did not predict survival multivariably.

Impact of the COVID-19 pandemic on the trajectory of the number of bronchoscopies performed in a tertiary hospital in Kyoto city.

The coronavirus disease 2019 (COVID-19) pandemic has restricted many medical practices. We aimed to investigate the impact of the COVID-19 pandemic on the number of bronchoscopies, outpatients, and hospital admissions. We retrospectively analyzed the number of outpatients, admissions, and bronchoscopies performed between March 2020 and May 2022. We defined "Peak month of the pandemic," "Wave of the pandemic," "Month in the wave," and "Period of a state of emergency" for each analysis. In the first year of the COVID-19 pandemic, analysis of variance (ANOVA) in linear mixed models indicated significant effects of "month in each wave" on the number of bronchoscopies (P = .003), outpatients (P = .041), and admissions (P = .017). The number of outpatients, admissions, and bronchoscopies was significantly influenced by the first wave of the COVID-19 pandemic. In contrast, in the second year of the COVID-19 pandemic, a mixed-ANOVA indicated significant effects of "month in each wave" only on the number of outpatients (P = .020) but no significant effects on the number of bronchoscopies (P = .407) and admissions (P = .219). During the second year of the pandemic, the number of bronchoscopies and admissions was not significantly affected by the waves of the pandemic. There were no significant differences in the number of admissions and bronchoscopies between the fourth and sixth waves. Although the number of bronchoscopies was found to be significantly affected in the early stages of the COVID-19 pandemic, the impact of the pandemic was much more limited thereafter.

Laparoscopic pyeloplasty proficiency during a residency program after adoption of a standardized simulation training program is maintained during the COVID pandemic despite reduced surgery volume.

PURPOSE: To evaluate the effect of the standardized laparoscopic simulation training program in pyeloplasty, following its implementation and during the COVID-19 pandemic. MATERIAL AND METHODS: A retrospective chart review was performed at Hospital de Clínicas de Porto Alegre, a tertiary referral center in south Brazil, in which 151 patients underwent laparoscopic pyeloplasty performed by residents between 2006-2021. They were divided into three groups: before and after adoption of a standardized laparoscopic simulation training program and during the COVID-19 pandemic. The main outcome was a combined negative outcome of conversion to open surgery, major postoperative complications (Clavien-Dindo III or higher) or unsuccessful procedure, defined as need for redo pyeloplasty. RESULTS: There was a significant reduction in the combined negative outcome (21.1% vs 6.3%), surgical time (mean 200.0 min vs 177.4 min) and length of stay (median 5 days vs 3 days) after the adoption of simulation training program. These results were maintained during the COVID-19 pandemic (combined negative outcome of 6.3%, mean surgical time of 160.1 min and median length of stay of 3 days) despite a reduction in 55.4% of the surgical volume. CONCLUSION: A structured laparoscopic simulation program can improve outcomes of laparoscopic pyeloplasty during the learning curve.

Presence of mediastinal lymphadenopathy in hospitalized Covid-19 patients in a tertiary care hospital in Pakistan-A cross-sectional study.

BACKGROUND: The aim of this study was to investigate the presence of mediastinal lymphadenopathy in hospitalized Covid-19 patients in a tertiary care hospital in the metropolitan city of Lahore, Pakistan from September 2020 till July 2021. METHODS: We retrospectively collected data of Covid-19 patients hospitalized from September 2020 till July 2021. Only those patients who tested PCR positive through a nasopharyngeal swab, were enrolled in the study. Patients' whose data were missing were excluded from this study. Our exclusion criteria included patients who tested negative on Covid-19 PCR, patients with comorbidities that may cause enlarged mediastinal lymphadenopathies such as haemophagocytic lymphohistiocytosis, neoplasia, tuberculosis, sarcoidosis or a systemic disease. The extent of lung involvement in Covid-19 patients was quantified by using a 25-point visual quantitative assessment called the Chest Computed Tomography Score. This score was then correlated with the presence of mediastinal lymphadenopathy. FINDINGS: Of the 210 hospitalized patients included in the study, 131 (62.4%) had mediastinal lymphadenopathy. The mean and median Severity Score of Covid-19 patients with mediastinal lymphadenopathy (mean: 17.1, SD:5.7; median: 17, IQR: 13-23) were higher as compared to those without mediastinal lymphadenopathy (mean: 12.3, SD:5.4; median: 12, IQR:9-16). INTERPRETATION: Our study documents a high prevalence of mediastinal lymphadenopathy in hospitalized patients with Covid-19 with the severity score being higher in its presence representing a more severe course of disease.

Critical Illness-Related Corticosteroid Insufficiency (CIRCI) Among Patients with COVID-19 at a Tertiary Hospital: Clinical Characteristics and Outcomes.

Objectives: Among critically ill patients, there is usually impairment of the hypothalamic-pituitary-adrenal axis, leading to a condition known as critical illness-related corticosteroid insufficiency (CIRCI). This investigation aims to determine the incidence of and characterize CIRCI among patients with COVID-19 as well as to analyze the outcomes of these critically ill patients. Methodology: This is a single-center, retrospective cohort study that investigated the occurrence of CIRCI among critically ill patients infected with COVID-19. Results: In this cohort, there were 145 COVID-19-positive patients with refractory shock, which reflects that 22.94% of the COVID-19 admissions have probable CIRCI.Patients who were given corticosteroids were found to have statistically significant longer median days on a ventilator (p=0.001). However, those on the corticosteroid arm were at higher risk of morbidity and mortality and a greater proportion had organ dysfunction. Multivariable logistic regression analysis revealed that SOFA score was a significant predictor of mortality in CIRCI (p=0.013). Conclusion: CIRCI has a unique presentation among patients with COVID-19 because of the presence of a high level of inflammation in this life-threatening infection. It is possibly a harbinger of a markedly increased risk of mortality in these patients.

Safety of COVID-19 vaccine in patients with myasthenia gravis: a self-controlled case series study.

Background: The safety of COVID-19 vaccines has been clarified in clinical trials; however, some immunocompromised patients, such as myasthenia gravis (MG) patients, are still hesitant to receive vaccines. Whether COVID-19 vaccination increases the risk of disease worsening in these patients remains unknown. This study aims to evaluate the risk of disease exacerbation in COVID-19-vaccinated MG patients. Methods: The data in this study were collected from the MG database at Tangdu Hospital, the Fourth Military Medical University, and the Tertiary Referral Diagnostic Center at Huashan Hospital, Fudan University, from 1 April 2022 to 31 October 2022. A self-controlled case series method was applied, and the incidence rate ratios were calculated in the prespecified risk period using conditional Poisson regression. Results: Inactivated COVID-19 vaccines did not increase the risk of disease exacerbation in MG patients with stable disease status. A few patients experienced transient disease worsening, but the symptoms were mild. It is noted that more attention should be paid to thymoma-related MG, especially within 1 week after COVID-19 vaccination. Conclusion: COVID-19 vaccination has no long-term impact on MG relapse.

Study of Characteristics of COVID-19 Patients with Fatal Outcome during Wave-2 from a Tertiary Care Center in Western India.

BACKGROUND: A large surge of intensive care unit (ICU) admissions leading to mortal outcome was observed in wave-2 of coronavirus disease 2019 (COVID-19) due to the higher virulence of the Delta variant of the COVID-19 virus, which led to the scarcity of resources in hospitals. This study was done to observe the clinical characteristics of COVID-19 patients with fatal outcomeMaterials and methods: We conducted a retrospective cross-sectional study in adults with COVID-19 pneumonia having fatal outcome during wave-2 of COVID-19, and their clinical characteristics were studiedResults: Out of 136 patients included in the study, the most common risk factors leading to adverse outcome were in the male gender, age (middle and elderly), with hypertension and diabetes mellitus (DM) as predominant comorbidities, early onset dyspnea, high C-reactive protein (CRP), high neutrophil to lymphocyte ratio (NLR), high D-dimer, bilateral lower zone involvement of lungs in chest X-ray (CXR), and development of acute kidney injury (AKI)Conclusion: The characteristics of the severely ill COVID-19 patients highlighted in the study could help clinicians in the early identification and management of high-risk patients. This study would help with resource planning and preparation for further COVID-19 waves and future pandemics.

Arthralgia among Patients with COVID-19 Infection Admitted to the Department of Medicine of a Tertiary Care centre: A Descriptive Cross-sectional Study.

Introduction: COVID-19 is a global pandemic that has affected millions of people worldwide. It predominantly affects the respiratory tract causing various respiratory symptoms. It also causes various musculoskeletal symptoms in the form of arthralgia and myalgia which may be incapacitating for some patients. The objective of this study was to find out the prevalence of arthralgia among patients with COVID-19 infection admitted to the Department of Medicine. Methods: This descriptive cross-sectional study was carried out in the Department of Internal Medicine of a tertiary care centre. Data from March 2020 to May 2021 were collected between 2 December 2021 and 20 December 2021 from the hospital records. Ethical approval was obtained from the Ethical Review Board (Reference number: 1312). All patients who were admitted with the diagnosis of COVID-19 infection based on positive Reverse Transcriptase-Polymerase Chain Reaction for COVID-19 were included in the study. Convenience sampling method was used. Point estimate and 95% confidence interval were calculated. Results: Among 929 patients included in the study, the prevalence of arthralgia was found to be 106 (11.41%) (10.30-12.51, 95% Confidence Interval). The mean age of these patients was 52.81±17.46 years. Conclusions: The prevalence of arthralgia in COVID-19-infected patients was similar to other similar studies done in similar settings. Keywords: arthralgia; COVID-19; prevalence; tertiary care.

COVID-19 associated infections in the ICU setting: A retrospective analysis in a tertiary-care hospital.

INTRODUCTION: Our work describes the frequency of superinfections in COVID-19 ICU patients and identifies risk factors for its appearance. Second, we evaluated ICU length of stay, in-hospital mortality and analyzed a subgroup of multidrug-resistant microorganisms (MDROs) infections. METHODS: Retrospective study conducted between March and June 2020. Superinfections were defined as appeared ≥48h. Bacterial and fungal infections were included, and sources were ventilator-associated lower respiratory tract infection (VA-LRTI), primary bloodstream infection (BSI), secondary BSI, and urinary tract infection (UTI). We performed a univariate analysis and a multivariate analysis of the risk factors. RESULTS: Two-hundred thirteen patients were included. We documented 174 episodes in 95 (44.6%) patients: 78 VA-LRTI, 66 primary BSI, 9 secondary BSI and 21 UTI. MDROs caused 29.3% of the episodes. The median time from admission to the first episode was 18 days and was longer in MDROs than in non-MDROs (28 vs. 16 days, p<0.01). In multivariate analysis use of corticosteroids (OR 4.9, 95% CI 1.4-16.9, p 0.01), tocilizumab (OR 2.4, 95% CI 1.1-5.9, p 0.03) and broad-spectrum antibiotics within first 7 days of admission (OR 2.5, 95% CI 1.2-5.1, p<0.01) were associated with superinfections. Patients with superinfections presented respect to controls prolonged ICU stay (35 vs. 12 days, p<0.01) but not higher in-hospital mortality (45.3% vs. 39.7%, p 0.13). CONCLUSIONS: Superinfections in ICU patients are frequent in late course of admission. Corticosteroids, tocilizumab, and previous broad-spectrum antibiotics are identified as risk factors for its development.

Anti-SARS-CoV-2 antibody among SARS-CoV-2 vaccinated vs post-infected blood donors in a tertiary hospital, Bangkok, Thailand.

SARS-CoV-2 virus infection has imposed a significant healthcare burden globally. To contain its spread and decrease infection-related mortality, several vaccines have been deployed worldwide in the past 3 years. We conducted a cross-sectional seroprevalence study to assess the immune response against the virus among blood donors at a tertiary care hospital, Bangkok, Thailand. From December 2021 to March 2022, total of 1,520 participants were enrolled, and their past history of SARS-CoV-2 infection and vaccination was recorded. Two serology test, namely, quantitative IgG spike protein (IgGSP) and qualitative IgG nucleocapsid antibody (IgGNC) were performed. The median age of study participants was 40 years (IQR 30-48) and 833 (54.8%) were men. Vaccine uptake was reported in 1,500 donors (98.7%) and 84 (5.5%) reported the past infection history. IgGNC was detected in 46/84 donors with the past infection history (54.8%) and in 36 out of the rest 1,436 (2.5%) with no past history. IgGSP positivity was observed in 1484 donors (97.6%). When compared to unvaccinated donors (n = 20), IgGSP level was higher in the donors who had received one vaccine dose (p< 0.001) and these antibody levels increased significantly among those with 3rd and 4th vaccine doses. Factors associated with low IgGSP (lowest quartile) by multivariate analysis included: no past infection history, homologous vaccination, < 3 vaccine doses, and > 90 days duration since last vaccination. In conclusion, vaccine uptake among our study donors was high (98.7%) and IgGSP antibody was observed in nearly all the vaccinated donors (97.6%). Previous SARS-CoV-2 infection, use of heterologous vaccination, vaccines ≥ 3 doses, and duration of the last vaccination >90 days affected IgGSP levels. Use of serological assays were found beneficial in the evaluation and differentiation of immune response to vaccination, and natural infection including the identification of previous asymptomatic infections.

Cross-sectional study to describe the severity, bio-chemical associations, and final outcomes of COVID-19-associated rhino-orbital-cerebral mucormycosis in a tertiary hospital of East India.

Purpose: The second wave of coronavirus disease 2019 (COVID-19) pandemic triggered a mucormycosis epidemic in India. Diabetes mellitus and dysregulated immune response were contributors, and rhino-orbital-cerebral mucormycosis (ROCM) was the most common presentation. It is however not known whether bio-chemical parameters at presentation correlate with stage of ROCM or final outcome in terms of vision or mortality. Methods: This retrospective, hospital-based study included all in-patients of mucormycosis with ophthalmic manifestations at presentation admitted during June 1, 2021 to August 31, 2021. It aimed to evaluate the association between severity of infection, serum levels of HbA1c, ferritin, interleukin-6 (IL-6), C-reactive protein (CRP), and D-dimer levels at presentation and outcome. Results: There were altogether 47 eligible cases having a mean age of 48.8 ± 10.9 years with a male:female ratio of 2.6:1; forty-two (89.4%) had pre-existing diabetes, and five (10.6%) had steroid-induced hyperglycemia. The mean HbA1c among diabetics was 9.7 ± 2.1. HbA1c and serum CRP showed an increase over subsequent stages, which was not statistically significant (P = 0.31). IL-6 values for all stages were similar (P = 0.97). Only serum ferritin levels showed a statistically significant increase over stages (P = 0.04). IL-6 was significantly lower (P = 0.03) in patients who survived, whereas CRP levels were significantly lower in patients who had final visual acuity (VA) better than only perception of light (P = 0.03). Conclusion: Uncontrolled diabetes mellitus is a significant association of ROCM. Serum ferritin levels at presentation best correlate with extent of the disease. CRP levels are best to prognosticate cases that will have sufficient VA to carry on activities of daily living, whereas IL-6 levels are best associated with survival.

Chronic Kidney Disease among COVID-19 Patients Admitted in the Department of Medicine of a Tertiary Care Centre: A Descriptive Cross-sectional Study.

Introduction: Comorbidities are frequently seen in admitted COVID-19 patients most common being hypertension, diabetes, cardiovascular diseases and chronic kidney disease. Chronic kidney disease is a slowly progressive chronic illness due to the gradual loss of kidney function or structure. The available data regarding the prevalence of chronic kidney disease and COVID-19 comorbidities is still limited. The aim of this study was to find out the prevalence of chronic kidney disease among COVID-19 patients admitted to the Department of Medicine of a tertiary care centre. Methods: A descriptive cross-sectional study was done in the Department of Medicine of a tertiary care centre. Data of medical records between 1 August 2020 to 1 December 2022 were reviewed retrospectively. The data was collected from 20 January 2023 to 20 March 2023. Ethical approval was obtained from the Institutional Review Committee (Reference number: 646/2079/80). Data on chronic kidney disease patients among COVID-19 patients were collected from the hospital records. Convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated. Results: Among 584 COVID-19 patients admitted, the prevalence of chronic kidney disease was 43 (7.36%) (5.24-9.48, 95% Confidence Interval). A total of 30 (69.77%) were male and 13 (30.23%) were female with a mean age of 55±16.22 years. Conclusions: The prevalence of chronic kidney disease among COVID-19 patients admitted in the department of Medicine of a tertiary care centre was found to be slightly higher than other studies done in similar settings. Keywords: chronic kidney disease; COVID-19; prevalence; tertiary care centre.

Implication of COVID-19 pandemic on the incidence of Clostridioides difficile infection in a Greek tertiary hospital.

Introduction. C. difficile infection (CDI) represents an important global threat. In the COVID-19 era, the multifactorial nature of CDI has emerged.Hypothesis - Aim. The aim was to assess the impact of COVID-19 pandemic on the incidence of CDI in a Greek hospital.Methodology. A retrospective study was performed throughout a 51 month period (January 2018 to March 2022), divided into two periods: pre-pandemic (January 2018 to February 2020) and COVID-19 pandemic (March 2020 to March 2022). The effects of the pandemic compared to the pre-pandemic period on the incidence of CDI [expressed as infections per 10 000 bed days (IBD)] were studied using interrupted time-series analysis.Results. Throughout the study, there was an increase in the monthly CDI incidence from 0.00 to 11.77 IBD (P<0.001). Interrupted time-series disclosed an increase in CDI incidence during the pre-pandemic period from 0.00 to 3.36 IBD (P<0.001). During the COVID-19 pandemic period the linear trend for monthly CDI rose from 2.65 to 13.93 IBD (P<0.001). The increase rate was higher during the COVID-19 pandemic period (r2 = +0.47) compared to the pre-pandemic period (r1 = +0.16).Conclusion. A significant increase of CDI incidence was observed, with the rate of the rise being more intense during the COVID-19 pandemic.

The impact of COVID-19 on compliance to amblyopia treatment in a tertiary eye care center.

Purpose: To investigate the impact of the coronavirus disease 2019 (COVID-19) outbreak on compliance to amblyopia therapy from the perspective of parents of amblyopic children. Methods: The participants for the qualitative study were enrolled from the medical records of a tertiary eye care center during the COVID-19 pandemic. The trained researcher conducted telephonic interviews consisting of validated 15 open-ended questions for 15 min. The questions were related to patients' compliance toward amblyopia treatment and the date of follow-up with their practitioners. The data collected were entered on Excel sheets in the participant's own words and later converted to a transcript for analysis. Results: A total of 217 parents of children with amblyopia who were due for follow-up were contacted through telephone. The response rate for willingness to participate was only 36% (n = 78). Of these, 76% (n = 59) of parents reported that their child was compliant toward the treatment during the therapy period and 69% reported that their child was currently not on treatment for amblyopia. Conclusion: In the current study, we have observed that although reported compliance by parents during the therapy period was good, around 69% of patients had discontinued amblyopia therapy. The main reason for the discontinuation of therapy was the failure to visit the hospital during the scheduled follow-up with the eye care practitioner.

Clinical predictors of Covid-19 mortality in a tertiary hospital in Lagos, Nigeria: A retrospective cohort study.

Background: The predictors of mortality among patients presenting with severe to critical disease in Nigeria are presently unknown. Aim: The aim of this study was to identify the predictors of mortality among patients with COVID-19 presenting for admission in a tertiary referral hospital in Lagos, Nigeria. Patients and Methods: The study was a retrospective study. Patients' sociodemographics, clinical characteristics, comorbidities, complications, treatment outcomes, and hospital duration were documented. Pearson's Chi-square, Fischer's Exact test, or Student's t-test were used to assess the relationship between the variables and mortality. To compare the survival experience across medical comorbidities, Kaplan Meir plots and life tables were used. Univariable and multivariable Cox-proportional hazard analyses were conducted. Results: A total of 734 patients were recruited. Participants' age ranged from five months to 92 years, with a mean ± SD of 47.4 ± 17.2 years, and a male preponderance (58.5% vs. 41.5%). The mortality rate was 9.07 per thousand person-days. About 73.9% (n = 51/69) of the deceased had one or more co-morbidities, compared to 41.6% (252/606) of those discharged. Patients who were older than 50 years, with diabetes mellitus, hypertension, chronic renal illness, and cancer had a statistically significant relationship with mortality. Conclusion: These findings call for a more comprehensive approach to the control of non-communicable diseases, the allocation of sufficient resources for ICU care during outbreaks, an improvement in the quality of health care available to Nigerians, and further research into the relationship between obesity and COVID-19 in Nigerians.

COVID-19 among Patients Visiting the Department of Emergency of a Tertiary Care Centre: A Descriptive Cross-sectional Study.

Introduction: Because of the unbridled transmissibility of the SARS-CoV-2 worldwide, researchers and healthcare professionals have set a common goal for timely diagnosis and future prevention of the disease. The aim of this study was to find out the prevalence of COVID-19 among patients visiting the Department of Emergency of a tertiary care centre. Methods: This descriptive cross-sectional study was conducted among the individuals suspected COVID-19 who had visited the Department of Emergency of a tertiary care centre between 11 January 2021 and 29 December 2021. Ethical approval was taken from Ethical Review Board (Reference number: 2768). Socio-demographic details, clinical symptoms, and two nasopharyngeal swab samples (one in viral transport medium to run RT-PCR and the other for Ag-RDT) were collected from each individual. Convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated. Results: Among the 232 patients, COVID-19 was detected in 108 (46.55%) (40.13-52.97, 95% CI) by Ag-RDT. A total of 44 (39.63%) of age groups 31-40 years were predominantly infected with SARS-CoV-2. The mean age was 32.13±10.80 years and was mostly males 73 (65.77%). Fever was present in 57 (51.35%) and dry cough was present in 50 (45.05%) COVID-19 patients. Conclusions: The prevalence of COVID-19 among hospitalized individuals in this study was higher than in previous studies conducted in similar settings. Keywords: COVID-19; Nepal; prevalence; SARS-CoV-2.

Mean Brixia Severity Scores among Symptomatic COVID-19 Patients in a Tertiary Care Centre: A Descriptive Cross-sectional Study.

Introduction: COVID-19 is a highly contagious viral disease which escalated into a global pandemic since its outbreak on 31 December 2019. Chest X-rays are the most common investigation in suspected cases to diagnose and manage pneumonia. The aim of this study was to find out the mean Brixia severity scores among symptomatic COVID-19 patients in a tertiary care centre.
