Background: Candida auris (C. auris) is an emerging healthcare-associated pathogen resulting in significant morbidity and mortality. The aim of this study is to report data from the national C. auris surveillance system for 2019 and conduct a survival analysis of the reported cohort. Methods: a retrospective analysis was conducted for all C. auris cases reported nationally to the Oman Antimicrobial Surveillance System (OMASS) in 2019, and isolates were sent to the Central Public Health Laboratories (CPHL). Clinical and demographic data were obtained through the E-Surveillance reporting system and the Electronic System (NEHR Al-Shifa) at CPHL. Statistical analysis was done using Kaplan–Meier analysis and Cox proportional hazard models. Results: One hundred and twenty-nine isolates of C. auris were grown from 108 inpatients; 87% were isolated from clinical samples, of which blood was the most common (38.9%). Forty (37%) were ≥65 years of age, 72 (66.7%) were males, and 85 (78.7%) were Omani nationals. Of the total isolates, 43.5% were considered as colonization; 56.5% were considered infection, of which 61.8% of them were candidemia. At least one risk factor was present in 98.1% of patients. The mean time from admission to infection was 1.7 months (SD = 2.8), and the mean length of hospital stay was 3.5 months (SD = 4). Totals of 94.8% and 96.1% of the isolates were non-susceptible to fluconazole and amphotericin, respectively. The variables found to be significantly associated with longer survival post C. auris diagnosis (p < 0.05) were age < 65 years, absence of comorbidities, length of stay < 3 months, colonization, and absence of candidemia. The infection fatality rate was 52.5%. Conclusion: Including C. auris in an ongoing antimicrobial surveillance program provides important data for the comprehensive management of this growing public health threat. The current study shows health care outbreaks of C. auris are ongoing, with 52.5% infection fatality, although our isolates remained sensitive to Echinocandins in vitro.

To describe the epidemiology, clinical and laboratory features, and outcome of children hospitalized with coronavirus disease 2019 (COVID-19) in the Middle East. A multicenter retrospective study of children hospitalized with COVID-19 in 7 centers across Oman between February and July 2020. In total, 56 children <14 years old required hospitalization in 7 Omani centers over 5 months (February – July 2020). Thirty-seven (68%) children were admitted with uncomplicated COVID-19, 13 (23%) with pneumonia and 5 (9%) with multisystem inflammatory syndrome in children. Infants constituted 41% of cases (23/56), approximately half of whom (12/23, 52%) were <2-months old. Fever was the most common symptom (46, 82%), followed by respiratory symptoms (33, 59%), and gastrointestinal symptoms (31, 55%). Twenty-two (39%) children had underlying medical conditions: sickle cell disease (7, 13%), chronic respiratory disease (4, 7%) and severe neurological impairment (4, 7%). Leukocytosis, elevated inflammatory markers and anemia were independently associated with intensive care admission. There were no mortalities related to admission with COVID-19 in this cohort. Most of the children hospitalized with COVID-19 had a mild course and a satisfactory outcome. Sickle cell disease is the most common comorbidity associated with pediatric admission of COVID-19 in Oman.

Background: Non-pharmaceutical interventions (NPIs), particularly mobility restrictions, are mainstay measures for the COVID-19 pandemic worldwide. We evaluated the effects of Oman’s mobility restriction strategies to highlight their efficacy in controlling the pandemic. Methods: Accessible national data of daily admissions and deaths were collected from 1 April 2020 to 22 May 2021. Google Community Mobility Report (CMR) data were downloaded for the same period. Among six CMR categories, three were used and reduced to one index—the community mobility index (CMI). We used a generalised linear model with a negative binomial distribution combined with a non-linear distributed lag model to investigate the short-term effects of CMI on the number of admitted PCR-confirmed COVID-19 cases and deaths, controlling for public holidays, day of the week, and Eid/Ramadan days. Results: We demonstrated the feasibility of using CMRs in the evaluation and monitoring of different NPIs, particularly those related to movement restriction. The best movement restriction strategy was a curfew from 7 p.m. to 5 a.m. (level 3 of CMI = 8), which had a total reduction of 35% (95% confidence interval (CI); 25–44%) in new COVID-19 admissions in the following two weeks, and a fatality reduction in the following four weeks by 52% (95% CI; 11–75%). Conclusion: Evening lockdown significantly affected the course of the pandemic in Oman which lines up with similar studies throughout the world.

In Oman, many extended families tend to live in one household. Some families can include 20–30 individuals with the majority of them being children. This study investigates the role of children in spreading SARS-CoV-2 causing COVID-19 within family clusters in Oman. This retrospective study includes data of 1026 SARS-CoV-2 positive children (≤18 years) collected from the national surveillance database for COVID-19 between 1 February 2020 and 30 May 2020. We included 1026 patients. Most, 842 were Omani (82%), 52% male, and 28.5% asymptomatic. Close to the half of symptomatic 419 (40%), patients presented with fever associated with other respiratory symptoms. Fifty pediatric patients were index cases who transmitted the virus to 107 patients in total (86 adults and 21 children) with a mode of 1. There is no statistical significance of all studied risk factors in the transmission of the SARS-CoV-2 virus including age, gender, and cycle threshold (CT) value. According to this study, children are not to be considered a significant driver of transmission of SARS-CoV-2 in Oman.

Background: Antibiotic overuse in Neonatal Intensive Care Units (NICUs) is a major contributor to antimicrobial resistance and adverse neonatal outcomes. This study aims to evaluate baseline antibiotic utilization (AU), identify factors influencing variability, and assess the impact of neonatal characteristics and sepsis incidence. Methods: A multicenter retrospective analysis examined AU in seven NICUs from 2019 to 2023, involving 25,532 neonatal admissions during national antibiotic stewardship program implementation. Data encompassed neonatal clinical parameters, sepsis incidence, and AU metrics, including days of therapy (DOT) per 1000 patient-days. Statistical analyses included correlation assessments and multivariate regression to identify determinants of antibiotic use. Results: Overall, 43.8% of neonates received antimicrobials, with individual NICUs ranging from 24% to 73% (p < 0.001). Antimicrobial-exposed neonates had a mean gestational age of 35.1 weeks [SD ± 4.4] and a mean birth weight of 2360 g [SD ± 970]. Antimicrobial-exposed neonates were generally more premature [35.1 (±4.4) weeks vs. 37.5 (±2.5) weeks (p < 0.001)] and had lower mean birth weight [2360 g (±971) vs. 2817 g (±686) (p < 0.001)] compared to those not exposed to antimicrobials. Total antimicrobial days varied markedly (8761 to 37,683 days), with DOT per 1000 patient-days ranging from 322 to 1031. Antimicrobial use for culture-negative sepsis varied widely among centers, from 23% to 73%. Antimicrobial-exposed neonates had higher all-cause mortality compared to those who did not [(7.5% vs. 3.2%), (p < 0.001)]. Multivariate analysis revealed individual NICU practice patterns remained significant predictors after adjusting for neonatal characteristics. Conclusions: Neonatal antimicrobial use varied significantly among NICUs, driven primarily by institutional practices rather than neonatal demographics. These findings provide nationally representative baseline data to inform neonatal antimicrobial stewardship interventions and offer transferable lessons for other countries seeking to optimize antibiotic use in NICUs amid rising global antimicrobial resistance.
