We used routinely collected programme data on people living with HIV in Oman who started ART in 2014–2018 to assess retention on ART, viral suppression, attrition (mortality or loss to follow-up [LTFU]) and treatment failure (attrition or HIV viral load of > 1000 copies/mL) 12 months after antiretroviral therapy (ART) initiation. We identified 726 patients; 72% were male. Overall, 12 months retention on ART and viral suppression (intention-to-treat [ITT] analysis) were 85.7% and 74.5%, respectively. Attrition occurred in 14.3% (mortality of 7% and LTFU of 7.3%). Retention increased from 78.8% (93/118) to 90.6% (144/159) among patients who started ART in 2014 and 2018, respectively. Similarly, ITT and on-treatment analyses revealed that viral suppression 12 months after ART initiation increased from 57.6% (68/118) and 73.1% (68/93) among patients who initiated therapy in 2014–80.5% (128/159) and 88.8% (128/144) among patients started treatment in 2018, respectively. On multivariate analysis, older age, having "Other" as an HIV risk factor (compared to heterosexual) and receiving HIV care outside the capital Muscat independently predicted both attrition and treatment failure. Our findings have been useful in identifying factors at the individual and programme level that influenced the risk of attrition and treatment failure. [ABSTRACT FROM AUTHOR]

- Abstract
Objectives: To tackle the issue of late HIV diagnosis in the country, the Ministry of Health (MOH) in Oman introduced a national policy of routine opt-out HIV in medical admission units in September 2022. We hereby report the implementation and outcomes of this policy., Method: All patients aged 16-65 years admitted to a medical ward in secondary and local hospitals were offered an HIV test regardless of their symptoms by medical doctors, with training and support from HIV teams. A retrospective review for the period from September 2022 to September 2023 was conducted to determine the HIV testing rate and outcomes of those testing HIV seropositive., Result: Over 12 months, there were 23,399 admissions; 6889 had HIV tests. Thirty-two patients (0.46 %) were diagnosed with HIV; all of them were new diagnoses. Two cases were diagnosed during seroconversion. 12 cases had AIDS-defining illnesses. Four contacts were tested HIV positive. Twenty-five out of 28 alive patients are on ART., Conclusion: This is the first national policy of a routine opt-out HIV in medical admission units in the MENA region. Our experience showed that, even in low HIV prevalence and high HIV stigma settings, this policy is feasible, acceptable, and effective., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Objectives: The main objective of the study is to describe the five lines of evidence of measles and rubella elimination in Oman., Methods: A descriptive record review of the national surveillance database of fever and rash illnesses (measles and rubella surveillance) to demonstrate elimination status., Results: A total of 532 and 73 cases of measles and rubella cases were reported during 2000-2022, respectively. Of the reported measles cases during 2000-2022, 106 were sporadic cases and 36 outbreaks (426 cases) were reported. The size of the outbreaks was largely small and the largest and the longest outbreak was in 2016-2017 involving the Dhofar-South Sharqiyah governorates with 90 cases due to genotype B3, which lasted for 32 weeks. Of the reported rubella cases during 2000-2022; all 73 were sporadic cases with no outbreaks. The vaccination coverage of Measles Mumps Rubella 2 is high (>98.0%) at the national and sub-national levels since 2008, thus maintaining the high population immunity. The absence of endemic genotype was proven through genetic sequencing of all the reported cases and outbreaks of measles and rubella. The high-performance indicators showed quality surveillance system., Conclusions: Oman fulfills the criteria for measles and rubella elimination. All the five lines of evidence were verified and Oman was certified to have eliminated measles and rubella in 2019. After 3 years of post-elimination, Oman has continued to maintain its elimination status successfully. High population immunity and quality surveillance resulted in sustaining the elimination during the post-elimination period., Competing Interests: The authors have no competing interests to declare., (© 2024 The Author(s).)

- Abstract
Objectives: To evaluate the prevalence of risk for venous thromboembolism (VTE) and the proportion of at-risk patients who receive appropriate thromboprophylaxis among inpatients in acute hospital care settings in Oman. A related objective was to evaluate the type and time of initiation of VTE prophylaxis., Methods: This multicenter, cross-sectional study was conducted in three tertiary hospitals in Oman. The study included acutely ill medical and surgical inpatients admitted from August to September 2022. VTE risk assessment and prophylaxis were assessed based on the 2012 recommendations of the American College of Chest Physicians (ACCP)., Results: A total of 384 patients were enrolled, 240 were medical patients and 144 were surgical patients. As per the ACCP criteria, 179 (74.6%) of medical and 92 (63.9%) of surgical patients were at risk for VTE and required prophylaxis. Appropriate prophylaxis was received by 142 (79.3%) at-risk medical and 70 (76.1%) at-risk surgical patients. In cases where pharmacological prophylaxis was contraindicated, mechanical prophylaxis was markedly underused. For medical patients, the median day of initiating VTE prophylaxis was day one of admission. For surgical patients, the median day of initiating VTE prophylaxis was postoperative day one., Conclusions: The majority of hospitalized patients in Oman are at risk of VTE. However, a significant minority of patients do not receive the required pharmacological or mechanical prophylaxis. We recommend the development of a national VTE risk assessment and guiding tool with a facility for monitoring compliance., (Copyright © 2024, Oman Medical Journal.)

- Abstract
Objectives: To assess outcomes and complications of patients with cerebral venous thrombosis (CVT)., Methods: This multicenter retrospective study was conducted at 2 health care centers in Saudi Arabia and Oman. Adult patients diagnosed with CVT in radiological imaging between 2006 and 2020 were included. Data were collected from medical records and analyzed using the software IBM® SPSS version 22. Neurological disability occurring after CVT was graded according to the modified Rankin scale (mRS)., Results: The study included 103 patients, of which the majority (68%) were female. The mean age was 39.12±12.96 years. Two-thirds of patients received low-molecular-weight heparin (LMWH) in acute treatment, while 76% of discharged patients used warfarin. The majority of patients had no or mild neurological disability during follow-up, and 6 patients had an mRS score ≥3, implying significant neurological disability. There were 55 patients (52.3%) who had complications from CVT, including seizures in 17 (16.5%) patients and one mortality. Follow-up imaging of 55 patients showed complete thrombus resolution in 20 patients (36%)., Conclusion: Anticoagulation is the mainstay treatment for CVT patients. Approximately half of patients experience complications. Prospective studies are needed to assess the long-term neurological outcomes in such patients., (Copyright: © Neurosciences.)

- Abstract
Polycystic ovarian syndrome (PCOS) is a common heterogeneous endocrine disease associated with a twofold higher risk of stroke and venous thromboembolism (VTE). An 18-year-old female presented to the emergency department (ED) with a one-hour history of right-side body weakness, facial asymmetry, and altered mental status. The patient had poor mentation and was unable to protect her airway. She was intubated and admitted to the intensive care unit (ICU). She was diagnosed with polycystic ovarian syndrome three years ago; however, she was not on active treatment at the time of presentation. She received two doses of the BNT162b2 mRNA COVID-19 vaccine, and her last dose was six months before the current presentation. A workup showed that she had extensive arterial and venous thrombosis. Later during investigations, she was found to have a complex atrial septal defect (ASD) with a left-to-right shunt. This case reports a management approach for a young female with untreated polycystic ovarian syndrome that predisposed her to develop deep vein thrombosis (DVT), pulmonary embolism (PE), and ischemic stroke due to atrial septal defect with possible transient shunt reversal., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Al Busaidi et al.)

- Abstract
Background: Tuberculosis (TB) remains a major public health issue. Elimination mandates collaboration between decision makers, practitioners and the community. Few studies address the knowledge, attitude and practice (KAP) from countries with low incidence., Aim: Assess KAP regarding TB in Oman., Method: A cross-sectional survey based on validated questionnaire conducted via phone on randomly selected participants., Results: A total of 1048 participants completed the questionnaire. Males accounted for 63% (n=664) of respondents, Omanis 76% (n=796) and 18-39-year-olds 50% (n=527). The overall knowledge was fair (53%), overall attitude scored good and fair (46%) equally and a good score (78%) for overall practice. While female gender associated with higher knowledge (53.9%, n=201), males showed higher attitude and practice, (48.5%, n=322) and (80.3%, n=533) respectively. Omani nationality correlated with higher knowledge (49.1%, n= 391) and attitude (46.9%, n=373) whereas non-Omani nationality correlated with higher practice (85.3%, n=214). Literacy was associated with higher knowledge (73.3%, n=11) and attitude (60%, n=9)., Conclusion: Despite efforts by the Ministry of Health, more must be done to raise TB knowledge to encourage preferable attitudes and practice. Interventions to improve KAP are required to speed up disease reduction rate. Utilization of different resources, especially digital platforms, for knowledge dissemination should consider community diversity, including the presence of expatriates., Competing Interests: Declaration of interests The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022.

- Abstract
Objectives: This study aimed to determine the pattern of clinical presentations associated with Chlamydia trachomatis and Neisseria gonorrhoeae infections., Methods: A retrospective cohort study was conducted between 2015 and 2020 and included patients attending Sultan Qaboos University Hospital, Muscat, Oman, who were tested for these infections using nucleic acid amplification., Results: A total of 408 women and 89 men were included. A total of 11 infections were identified in women (n = 11, 2.7%) and 14 in men (n = 14, 15.7%). Chlamydia accounted for almost all infections in women (n = 10, 90.9%), commonly presenting with lower abdominal pain or abnormal vaginal bleeding. In men, urethral discharge/dysuria syndrome was the most common presentation and chlamydia was identified in eight men and gonorrhoea in six; a majority of all infections were seen in patients ≤35 years old., Conclusion: The relative prevalence of two common sexually transmitted infections (STIs) among patients with genitourinary symptoms at a tertiary referral hospital have been described. The pattern of their presentations will inform the design of prospective studies to improve surveillance and guide public health policy in Oman. This study highlights the need for a multi-sectoral approach involving all providers to enable comprehensive STI surveillance., Competing Interests: CONFLICT OF INTERESTS The authors declare no conflict of interests., (© Copyright 2022, Sultan Qaboos University Medical Journal, All Rights Reserved.)

- Abstract
Background: Among the challenges to public health systems imposed by coronavirus disease 2019 (COVID-19) have been vaccine scarcity and the prioritization of high-risk groups. Countries have been prompted to accelerate the pace of immunization campaigns against COVID-19 to deploy the immunization umbrella to the largest possible number of target groups. In this paper, we share the perspective of Oman regarding the impact of accelerating the administration of the first dose of the COVID-19 vaccine in one border governorate (Musandam) by comparison to another border governorate (Al-Buraimi) where this approach was not applied., Methods: Daily admissions data (April 10, 2020 to June 24, 2021) and vaccination data (January 1 to June 24, 2021) were collected systematically. For each governorate, the cumulative doses (first and second doses) and vaccination coverage were calculated daily., Results: Within 1 month, first dose vaccination coverage increased from 20% to 58% in Musandam, reducing the incidence of hospital admission by 75%. In comparison, vaccination coverage plateaued at 20% in Al-Buraimi, and the incidence of hospital admission increased by 500%., Conclusions: Given the peculiarity of the geographical location and being the first line of access for imported cases, border regions should be a priority for vaccine deployment as a preventive measure. The two different approaches reported here, implemented in broadly similar cross-border governorates, provide evidence of the significant effect of accelerating the first dose of vaccine in reducing hospitalizations., (© 2022 The Authors.)

- Abstract
We conducted a cross-sectional analysis to determine the rate of retention in HIV care and the factors associated with loss to follow-up (LTFU) among Omani adults living with HIV who were linked to care as of 31 December 2019. Patients ( n = 1610) were identified from a central national HIV surveillance dataset. The majority (68.3%) of patients were male, and the median age was 39 years (IQR, 31-48 years). A total of 1480 patient (91.9%) were retained in care. On multivariate analysis, compared to those who received antiretroviral therapy (ART), patients who had never been on ART were 6.8 (95% CI: 3.05-15.16) times more likely to be lost to follow-up. Patients who had a latest HIV viral load (VL) of 200-999 copies/ml (adjusted odds ratio [aOR]: 4.92, 95% CI: 2.27-10.69) and ≥ 1000 copies/ml (aOR: 15.03, 95% CI: 8.31-27.19) compared to those who had a latest HIV VL of <200 copies/ml had higher odds of loss to follow-up. Moreover, patients who were divorced or widowed were 2.64 (95% CI: 1.14-6.07) times more likely to disengage from HIV services, compared to those who were married. These findings will be invaluable in developing targeted interventions that further improve patients' retention in HIV care in Oman.

- Abstract
Coronavirus disease (COVID-19) has been declared by the World Health Organization as a pandemic on March 11, 2020. COVID-19 predispose patients to multisystem thromboembolic events, including pulmonary emboli and deep vein thrombosis. We report a 33-year-old previously healthy man, with previous history of COVID-19 infection presented with left eye central retinal vein occlusion (CRVO) with secondary macular edema. All possible risk factors for thromboembolic events were excluded. After a single dose of intravitreal injection of aflibercept (2 mg in 0.05 ml), gradual improvement in the clinical manifestation of CRVO with complete resolution of macular edema in the left eye was observed. To the best of our knowledge, this is the first report of CRVO post-COVID-19 in Oman., Competing Interests: There are no conflicts of interest., (Copyright: © 2021 Middle East African Journal of Ophthalmology.)

- Abstract
Despite the apparent challenges inflicted by COVID-19 globally, the pandemic provided an opportunity to utilize and expand existing public health capacities for a more adaptive and resilient system during and after each wave of the disease. This paper provides a narrative review of Oman's public health response to the COVID-19 pandemic from January 2020 to July 2021, and the challenges it faced for a more rapid and efficient response. The review demonstrates that the three main pillars influencing the direction of the pandemic and aiding the control are Oman's unified governmental leadership, the move to expand the capacity of the health care system at all levels, and community partnership in all stages of the response including the COVID-19 vaccination campaign. The opportunities identified during response stages in the harmonization of the multisectoral response, streamlining communication channels, addressing vulnerable communities (dormitories, residences at border regions), and providing professional technical leadership provide an excellent precursor for expediting the transformation of Oman's health care system to one with a multisectoral holistic approach. Some of the major challenges faced are the shortage of the public health cadre, lack of a fully integrated digital platform for surveillance, and the scarcity of experts in risk communication and community engagement. A future health system where the center for diseases surveillance and control acts as a nucleus for multisectoral expertise and leadership, which includes community representatives, is crucial to attain optimum health. The destruction inflicted by this prolong COVID-19 pandemic at all levels of human life had valued the importance of investing on preventive and preparedness strategies., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Al Khalili, Al Maani, Al Wahaibi, Al Yaquobi, Al-Jardani, Al Harthi, Alqayoudhi, Al Manji, Al Rawahi and Al-Abri.)

- Abstract
Background: The aim of this study was to determine the proportions and predictors of late presentation (LP) and advanced HIV disease (AD) in Oman. LP and AD were defined as presenting with a baseline CD4 count of < 350 and < 200 cells/mm3, respectively., Methods: We conducted a retrospective database analysis of the National HIV Surveillance System to identify Omani people (≥ 13 years old) who were diagnosed with HIV in the period between January 2000 and December 2019 and had a documented baseline CD4 cell count. We calculated the rates and trend over time of LP and AD. A logistic regression was carried out to determine the predictors of LP and AD., Results: A total of 1418 patients, who were diagnosed with HIV in the period from January 2000 to December 2019, were included; 71% were male and 66% were heterosexuals. The median (IQR) age at diagnosis was 33 (25-39) years. Overall, 71% (95% CI: 68-73) and 46% (95% CI: 44-49) of patients had LP and AD at presentation, respectively. The LP percentage decreased from 76% in 2000-2004 to 69% in 2015-2019; AD percentage decreased from 57 to 46% over the same period. The proportions of men with LP and AD were higher than women (74% vs. 62 and 50% vs. 36%, respectively). The percentages of persons with LP among people aged 13-24, 25-49, and ≥ 50 years were 65, 71, and 84%, respectively. The proportions of persons with AD among people aged 13-24, 25-49, and ≥ 50 years were 39, 46, and 65%, respectively. Logistic regression showed that male sex, older age, having an "unknown" HIV risk factor, and living outside Muscat were independent predictors of AD. Male sex also independently predicted LP., Conclusions: This analysis indicates that a significant proportion of new HIV cases in Oman continue to present late. This study identified patient subgroups at greatest risk of late HIV diagnosis such as men and older people. Targeted interventions and greater efforts to scale up HIV testing services in Oman are needed., (© 2021. The Author(s).)

- Abstract
Objective: To assess the seroprevalence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in Oman and longitudinal changes in antibody levels over time within the first 11 months of the coronavirus disease 2019 (COVID-19) pandemic., Methods: This nationwide cross-sectional study was conducted as a four-cycle serosurvey using a multi-stage stratified sampling method from July to November 2020. A questionnaire was used and included demographics, history of acute respiratory infection and list of symptoms, COVID-19 contact, previous diagnosis or admission, travel history and risk factors., Results: In total, 17,457 participants were surveyed. Thirty percent were female and 66.3% were Omani. There was a significant increase in seroprevalence throughout the study cycles, from 5.5% (4.8-6.2%) in Cycle 1 to 22% (19.6-24.6%) in Cycle 4. There was no difference in seroprevalence between genders, but significant differences were found between age groups. There was a transition of seroprevalence from being higher in non-Omanis than Omanis in Cycle 1 [9.1% (7.6-10.9%) vs 3.2% (2.6-3.9%)] to being higher in Omanis than non-Omanis in Cycle 4 [24.3% (21.0-27.9%) vs 16.8% (14.9-18.9%)]. There was remarkable variation in the seroprevalence of SARS-CoV-2 according to governorate. Close contacts of people with COVID-19 had a 96% higher risk of having the disease [adjusted odds ratio (AOR) 1.96, 95% confidence intervals (CI) 1.64-2.34]. Labourers had 58% higher risk of infection compared with office workers (AOR 1.58, 95% CI 1.04-2.35)., Conclusion: This study showed a wide variation in the spread of SARS-CoV-2 across governorates in Oman, with higher estimated seroprevalence in migrants in the first two cycles. Prevalence estimates remain low and are insufficient to provide herd immunity., Competing Interests: Conflict of interest statement None declared., (Copyright © 2021 The Author(s).

- Abstract
Background: 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., Methods: 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., Results: 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., Conclusions: According to this study, children are not to be considered a significant driver of transmission of SARS-CoV-2 in Oman., (Copyright © 2021 The Author(s).

- Abstract
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.

- Abstract
Vaccination with ChAdOx1 nCov-19 can result in vaccine-induced immune thrombotic thrombocytopenia (VITT). This phenomenon mimics heparin-induced thrombocytopenia (HIT), yet it does not require heparin as a trigger. HIT screen/ELISA along with optical density and functional assay are useful in diagnosis. A 64-year-old man presented to the emergency department with intermittent fever and persistent, dull, nonspecific abdominal pain 7 days after the first dose of ChAdOx1 nCov-19 vaccine. Laboratory results showed significantly reduced platelet count, acute kidney injury, and low basal cortisol. He underwent investigations including computed tomography angiography, which revealed multiple sites of arterial and venous thrombosis. We present the first reported case of VITT at our institution and in Oman. This case highlights the potentially life-threatening complication associated with ChAdOx1 nCov-19 vaccine, clinical presentation, diagnostic approach, and treatment., (© 2021 The Authors.

- Abstract
There are currently no reliable epidemiological data for estimating the burden of sexually transmitted infections (STIs) in Oman. STIs such as gonorrhoea and chlamydia are often asymptomatic and associated with sexual and reproductive morbidity. An exploratory study was conducted in an antenatal clinic in Muscat, Oman, to assess the acceptability and feasibility of testing for gonorrhoea and chlamydia. Two hundred and twenty-one women were recruited over 14 weeks between July and October 2020. There were three cases of chlamydia (3/221, 1.36%); no cases of gonorrhoea were identified. Acceptability and feasibility for testing in this cohort of pregnant women were good despite anticipated cultural sensitivities surrounding sexually transmitted infections.

- Abstract
BACKGROUND The COVID-19 pandemic is an ongoing cause of the current global healthcare crisis. Several vaccines were approved for use by emergency vaccination campaigns worldwide. At present, there are very few reports of COVID-19 vaccine-induced immune-thrombotic thrombocytopenia, a variant of heparin-induced thrombocytopenia (HIT), in comparison to the massive number of vaccinated people worldwide. CASE REPORT A 59-year-old woman presented to the Emergency Department with a 3-day history of sudden-onset left leg pain 7 days after receiving her first dose of BNT162b2 mRNA COVID-19 (Pfizer-BioNTech). She was diagnosed with deep vein thrombosis (DVT) and pulmonary embolism (PE) and found to have a positive HIT screen with optical density (OD) of 0.6 via ELISA test. She was hospitalized for 4 days and discharged home with an oral anticoagulant (rivaroxaban). CONCLUSIONS This case report describes a possible link between BNT162b2 mRNA COVID-19 (Pfizer-BioNTech) vaccination and thromboembolism. However, further data are needed to support such an association.

- Abstract
Oman is globally acknowledged for its well-structured immunization program with high vaccination coverage. The massive spread of misinformation brought on by the COVID-19 pandemic, as well as the easy access to various media channels, may affect acceptance of a vaccine, despite the inherent trust in the local system. This cross-sectional study evaluated the knowledge, attitudes, and practice (KAP) in Oman toward COVID-19 vaccines. It included 3000 randomly selected adults answering a structured questionnaire via telephone. Participants were 66.7% Omani, 76% male, and 83.7% without comorbidities. Their mean age was 38.27 years (SD ± 10.45). Knowledge of COVID-19's symptoms, mode of transmission, and attitudes toward the disease was adequate; 88.4% had heard of the vaccine, 59.3% would advise others to take it, 56.8% would take it themselves, and 47.5% would take a second dose. Males (CI = 2.37, OR = (2.00-2.81)) and Omani (CI = 1.956, OR = (4.595-2.397)) were more willing to be vaccinated. The history of chronic disease, source of vaccine knowledge, and education level were factors that affected the willingness to accept the vaccine. The Omani community's willingness to take the COVID-19 vaccine can be enhanced by utilizing social media and community influencers to spread awareness about the vaccine's safety and efficacy.

- Abstract
Objectives: The aim of the current study was to describe COVID-19's epidemiological characteristics in Oman during the initial stages of the outbreak and compare findings with other countries' reports., Methods: Data were drawn from a descriptive, records-based review of reported cases of COVID-19 collected through the national COVID-19 Surveillance System from February to April 2020., Results: A total of 2,443 confirmed cases were reported during the study period. The overall first-time testing rate for this period was 851.7 per 100,000, the positivity rate was 53.1 (confidence intervals [CI]: 51.0-55.2) and the death rate was 0.32 (CI: 0.20-0.54) per 100,000 population, respectively. The overall national positive ratio was 5.7% and ranged from 2.2-7.1% across various governorates. Muscat Governorate had the highest positive ratio (12.5%). People in the 51-60 year old age group (RR = 1.97), males (RR = 1.24), non-Omanis (RR = 2.33) and those living in Muscat (RR = 2.14) emerged as categories with significant demographic risk for COVID-19 cases when compared to the national average. The mean age was 35.6 ± 13.4. Asymptomatic cases accounted for nearly 16%., Conclusion: The overall rate of COVID-19 cases and deaths were low in Oman compared to the rest of the world during the study period., Competing Interests: CONFLICT OF INTEREST The authors declare no conflicts of interest., (© Copyright 2021, Sultan Qaboos University Medical Journal, All Rights Reserved.)

- Abstract
Background: In January 2016, the National AIDS Programme (NAP) in Oman introduced a package of interventions, including capacity building for service providers, to improve the quality of HIV services., Aims: To report the impact of these interventions on the rate of vertical HIV transmission in the period from January 2016 to December 2019. We also describe the virological and obstetric outcomes for HIV-infected pregnant women., Methods: This was a medical record review of 94 HIV-positive pregnant women (median age 32 years; interquartile range 25-34 years) reported to NAP in 2016-2019., Results: There were 110 pregnancies in 94 women. The majority (75.3%, 61/81) of women were diagnosed with HIV infection from routine antenatal screening, with 60% (66/110) of pregnancies occurring in women who knew their HIV status at conception. Caesarean section was the most common (50%) mode of delivery. The preterm labour and low birth weight rates were 21.2% and 15.9%, respectively. The antiretroviral coverage during pregnancy was 95.5%, with most (87.8%) women reporting excellent or good adherence. The majority (81.6%) of women achieved HIV viral load of < 400 copies/ml at or near delivery. Almost all infants (99%) were given prophylactic antiretrovirals. The rate of mother-to-child transmission of HIV was 1%., Conclusion: The obstetric and virological outcomes for HIV-infected pregnant women delivered in 2016-2019 were favourable, with a low rate of mother-to-child transmission of HIV. Oman is now in the process of finalizing application of World Health Organization validation of elimination of mother-to-child transmission of HIV., (Copyright © World Health Organization (WHO) 2021.

- Abstract
Background: Mortality surveillance provides a crucial method for monitoring disease activity. Coronavirus disease 2019 (COVID-19) can cause excess mortality both directly and indirectly by increasing deaths from other diseases. The aim of this study was to investigate the effects of COVID-19 on mortality in Oman., Methods: A cross-sectional retrospective analysis of mortality data from 1 January 2015 to 16 August 2020 was undertaken. Baseline mortality estimated using the Farrington flexible model and excess mortality were calculated for the pandemic period (16 March-16 August 2020) according to cause of death, place of death and age group., Results: During the pandemic period, there was a 15% [95% confidence interval (CI) 14-17] increase in all-cause mortality from baseline. When classifying by cause, there was a 9% (95% CI 5-12) increase in deaths due to respiratory diseases, a 2% (95% CI 1-4) increase in deaths due to infectious diseases and a 9% (95% CI 8-11) increase in unclassified deaths. In terms of place of death, 12% (95% CI 11-14) of excess mortality occurred in hospitals and 7% (95% CI 5-8) occurred in homes during the pandemic period. Patients aged >60 years recorded a 15% (95% CI 13-16) increase in all-cause mortality during this period., Conclusion: The COVID-19 pandemic has resulted in a 15% increase in all-cause mortality in Oman, mainly as a result of deaths from COVID-19. However, unclassified deaths, deaths due to respiratory diseases and deaths due to infectious diseases have also increased, enforcing the need for a holistic approach and appropriate coordination of health services during such health crises., (Copyright © 2020 The Author(s).

- Abstract
We conducted a cross-sectional analysis to determine HIV virologic failure and its associated factors among Omani people living with HIV who are on ART for > 6 months. Patients (n = 1427) were identified from a central national HIV surveillance dataset. Two-thirds (67%) of patients were male, and the median age was 39 years (IQR, 32-48 years). Out of 1427 patients, 14.4% had virologic failure (HIV viral load [VL] ≥ 200 copies/ml). The multivariate analysis showed that patients aged 25-49 years (adjusted odds ratio [aOR]: 1.76, 95% CI: 1.01-3.08) were significantly more likely to fail treatment, compared to those aged ≥ 50 years. Besides, having "Other" HIV risk factor (compared to heterosexuals, aOR: 1.82, 95% CI: 1.02-3.24) and receiving HIV care outside the capital Muscat (compared to those cared for in Muscat, aOR: 1.73, 95% CI: 1.11-2.7) were independently associated with virologic failure. HIV viral suppression (85.6%) in Oman is encouraging; however, further strategies, mainly targeting patients who are young (<50 years), those not disclosing their HIV risk factor and those attending HIV treatment centres outside Muscat, are required to enhance HIV treatment outcome in Oman.

- Abstract
In this paper, we present a multicentre record-based descriptive study used to estimate the incidence and characterize the spectrum of confirmed bacille Calmette-Guérin (BCG) vaccine-related disease among children in Oman. This study included all children (age ≤ 14 years) who had culture and/or polymerase chain reaction (PCR)-confirmed BCG disease from January 2006 to December 2018, as identified from Central Public Health Laboratory data and International Classification of Diseases coding of an electronic patient information system. In total, 88 children confirmed to have BCG disease were included in the study, making an average incidence of 9.2 cases per 100,000 vaccinated neonates. The males comprised 65.9%, Omanis 93.2%, and the median age of presentation was 4 months in children with BCG disease. The most common type of disease was BCG abscesses (72.4%). Children with immunodeficiency and those presenting within 6 months were found to have a more severe and disseminated disease. In total, 28 children had immunodeficiency. The age of presentation and type of BCG disease was significantly associated with immunodeficiency status. The majority of cases required therapy (both medical and surgical) and recovered well. The incidence of laboratory-confirmed BCG vaccine-related disease was low in Oman supporting continuing the use of the BCG vaccination practice at birth.

- Abstract
Cardiac complications are the major cause of mortality in patients with Thalassemia major (TM). Cardiac T2* MRI is currently the gold standard for assessing myocardial iron concentration. The aim of our study was to assess whether any echocardiographic parameter would correlate with these findings in patients well established on chelation therapy. This was a prospective study on patients with TM who are regularly followed in our clinic. Patients had a cardiac MRI and echocardiogram within 2 months of each other. Echo parameters included global longitudinal strain and diastolic function. We also compared these findings with those from a cohort of thalassemia intermedia (TI) and normal controls. A total of 84 patients (mean age 26.3 ± 6.1 years, 42.8% male) with TM were enrolled. All had normal left ventricular ejection fraction and only 8 patients had MRI T2* < 10. As compared to 17 patients with TI and 53 controls, these patients had significantly higher E/E' and lower pulmonary vein s/dd ratio suggesting early diastolic dysfunction. 28 patients fulfilled criteria for diastolic dysfunction even in the presence of normal MRI T2*. Global longitudinal strain (GLS) was significantly lower in the TM group as compared to the TI and controls. We found no correlation between any of the echo findings and the MRI T2*in TM patients. In patients with thalassemia and MRI T2* > 20 ms features of diastolic dysfunction persist even in the presence of normal LV function and normal GLS. This suggests that diastolic function remains abnormal even when myocardial iron concentrations are normal and follow up therefore is essential.

- Abstract
Background: COVID-19's emergence carries with it many uncertainties and challenges, including strategies to manage the epidemic. Oman has implemented non-pharmaceutical interventions (NPIs) to mitigate the impact of COVID-19. However, responses to NPIs may be different across different populations within a country with a large number of migrants, such as Oman. This study investigated the different responses to NPIs, and assessed the use of the time-varying reproduction number (R
t ) to monitor them., Methods: Polymerase chain reaction (PCR) laboratory-confirmed COVID-19 data for Oman, from February 24 to June 3, 2020, were used alongside demographic and epidemiological information. Data were arranged into pairs of infector-infectee, and two main libraries of R software were used to estimate reproductive number (Rt ). Rt was calculated for both Omanis and non-Omanis., Findings: A total of 13,538 cases were included, 44.9% of which were Omanis. Among all these cases we identified 2769 infector-infectee pairs for calculating Rt . There was a sharp drop in Rt from 3.7 (95% confidence interval [CI] 2.8-4.6) in mid-March to 1.4 (95% CI 1.2-1.7) in late March in response to NPIs. Rt then decreased further to 1.2 (95% CI 1.1-1.3) in late April after which it rose, corresponding to the easing of NPIs. Comparing the two groups, the response to major public health controls was more evident in Omanis in reducing Rt to 1.09 (95% CI 0.84-1.3) by the end of March., Interpretation: Use of real-time estimation of Rt allowed us to follow the effects of NPIs. The migrant population responded differently than the Omani population., (Copyright © 2020 The Author(s). Published by Elsevier Ltd.. All rights reserved.)- Published

- Abstract
To fulfil the World Health Organization (WHO) End TB strategy, screening for tuberculosis (TB) in immigrants is an important component of the strategy to reduce the TB burden in low-incidence countries. Oman has an annual TB incidence rate of 5.7 per 100000 and transmission from migrants with activated latent TB infection (LTBI) to nationals is a concern. The aim of this study was to determine the proportion of migrants to the Sultanate of Oman with LTBI. The study used an interferon-gamma release assay (IGRA) to assess previous exposure to TB, defining LTBI and a positive IGRA with a normal chest X-ray. 1049 subjects were surveyed. Six participants were excluded from the analysis as they had been recently vaccinated and 1 had an indeterminate result, thus 1042 subjects were included. The overall IGRA-positive rate was 22.4% (234/1042), 30.9% and 21.2% of African and Asian migrants, respectively, were IGRA-positive. Fifty-eight of the participants had a strong IGRA reactivity defined as more than 4 IU/ml. The study shows the proportion of migrants from Asia and Africa with LTBI and 24.7% (58/234) of IGRA-positive migrants had an IGRA of >4 IU/ml, defining a subpopulation with a high risk of developing active TB in the first two years of arrival to the country., (Copyright © 2020 Elsevier Ltd.

- Abstract
We used population-based data on all diagnosed people living with Human Immunodeficiency (HIV) reported to the National AIDS Programme in 1984-2018 to describe the HIV epidemiology in Oman. A total of 3060 Omanis were diagnosed with HIV from 1984 to 2018. The proportions of new infections attributed to sexual contact accounted for 56.3% (376/668) in 1984-1996 compared with 80.7% (630/780) in 2013-2018. Of 1417 patients with a documented CD4 count at the entry of care, 45.3% had a baseline CD4 count of <200 cells/mm
3 . Compared with heterosexuals, homosexuals had higher rates of advanced HIV disease [42.7% (388/908) vs 50.4% (136/270), respectively]. Rates of advanced disease and death within a year of HIV diagnosis rose consistently with age at diagnosis. Approximately half (48.8%) of the patients diagnosed in 1984-2018 had died by December 2018. The majority (85.6%; 572/668) of people who were diagnosed in 1984-1997 had died compared with 12.7% (99/780) of those diagnosed in 2013-2018. However, people died more recently had a higher proportion of death within a year of HIV diagnosis [74.7% (74/99) in 2013-2018 compared with 13.8% (79/572) in 1984-1996]. This study shows that the HIV epidemic in Oman is a low-prevalence one. Of concern, a large proportion of new HIV diagnoses continued to present late, which has resulted in a substantial increase in short-term mortality over the past 20 years. Nevertheless, we observed a remarkable decline in overall mortality over time, which may be explained by the improvement in the quality of HIV care in Oman., Competing Interests: The authors declare they have no conflicts of interest., (© 2020 The Authors.

- Abstract
β-thalassaemia major is an autosomal recessive form of haemoglobinopathy that is characterised by complete lack of production of the β-chains resulting in multiple complications that include severe anaemia, failure to thrive and skeletal abnormalities. Facial deformities induced by β-thalassaemia major are rare and are very challenging to treat from a surgical point of view. We report a 33-year-old female patient with β-thalassaemia major who presented to the Dental & Maxillofacial Surgery Department, Sultan Qaboos University Hospital, Muscat, Oman, in 2017 with gross dentofacial skeletal deformity contributing to her psychosocial issues. The facial deformity was corrected surgically by excision of the enlarged maxilla, modified Le Fort I osteotomy and advancement genioplasty. This case highlights the pre-operative preparation, surgical management, encountered complications and treatment outcome within 24 months of follow-up., (© Copyright 2020, Sultan Qaboos University Medical Journal, All Rights Reserved.)

- Abstract
Background: Venous thromboembolism (VTE), which includes deep vein thrombosis (DVT) and pulmonary embolism (PE), is a known cause of morbidity and mortality after bariatric surgery. However, the data concerning appropriate thromboprophylaxis after bariatric surgery is uncertain. The objective of this study was to evaluate the efficacy and safety of extended duration thromboprophylaxis in post-bariatric surgery patients., Methods: We conducted a retrospective study of consecutive patients who underwent bariatric surgery from November 2014 to October 2018 at King Fahad General Hospital in Jeddah, Saudi Arabia. All included patients were treated with extended duration thromboprophylaxis., Results: We identified 374 patients who underwent bariatric surgery during the study period. Of these, 312 patients (83%) were followed for at least 3 months. The most common type of surgery was a laparoscopic sleeve gastrectomy (N=357) and the median weight was 110 kg. The cumulative incidence of symptomatic postoperative VTE at 3 months was 0.64% (95% confidence interval, 0.20-1.52). All events occurred after hospital discharge. The most commonly used pharmacological prophylaxis (91%) for VTE prevention after bariatric surgery was enoxaparin 40 mg subcutaneously twice daily for 10-14 days after hospital discharge. There were no reported cases of bleeding or VTE related mortality after 3 months., Conclusion: Extended thromboprophylaxis after bariatric surgery appears to be an effective and safe strategy for VTE prevention. Large prospective studies are needed to evaluate the optimal thromboprophylaxis regimen after bariatric surgery., Competing Interests: Authors' Disclosures of Potential Conflicts of Interest: No potential conflicts of interest relevant to this article were reported., (© 2020 Korean Society of Hematology.)

- Abstract
Following the detection of the first human case of avian influenza A subtype H9N2 in 1998, more than 40 cases were diagnosed worldwide. However, the spread of the virus has been more remarkable and significant in global poultry populations, causing notable economic losses despite its low pathogenicity. Many surveillance studies and activities conducted in several countries have shown the predominance of this virus subtype. We present the case of a 14-month-old female in Oman with an A(H9N2) virus infection. This is the first human case of A(H9N2) reported from Oman and the Gulf Cooperation Countries, and Oman is the second country outside of southern and eastern Asia to report a case (cases have also been detected in Egypt). The patient had bronchial asthma and presented with a high-grade temperature and symptoms of lower respiratory tract infection that necessitated admission to a high dependency unit in a tertiary care hospital. It is of urgency that a multisector One Health approach be established to combat the threat of avian influenza at the animal-human interface. In addition to enhancements of surveillance and control in poultry, there is a need to develop screening and preventive programs for high-risk occupations., (Copyright © 2019 The Author(s).

- Abstract
Objective: To evaluate the cascade of HIV care in Oman in 2018 and the longitudinal change in each step from 2015 to 2018., Methods: Population-based data on all diagnosed people living with HIV reported to the National AIDS Programme in 1984-2018 were used., Results: As of December 31, 2018, the estimated number of people living with HIV in Oman was 3030; 1532 (50.6%) were aware of their infection. Of the diagnosed patients, 95.9% were linked to care, 85.8% were retained in care, and 84.3% were on ART. The proportions of patients with viral suppression out of all people with HIV, the diagnosed persons, and those on ART were 37.3%, 73.7%, and 87.5%, respectively. The proportion of patients linked to care increased from 72.6% in 2015 to 95.6% in 2018 (p < 0.001). Only 57% (947/1661) were retained in care in 2015, which increased to 76.9% (1193/1552) in 2017 and 85.8% (1314/1532) in 2018 (p < 0.001). Viral suppression increased from 75.7% (672/888) in 2015 to 84.5% (859/1017) in 2016 and 87.5% (1129/1291) in 2018 (p < 0.001)., Conclusions: A sustained improvement in linkage to care, retention in care, ART coverage, and viral suppression was observed amongst people living with HIV in Oman in 2015-2018., (Copyright © 2019 The Author(s).

- Abstract
Background: In December 2018, routine surveillance identified an autochthonous outbreak of dengue fever in Muscat Governorate, Oman, a region previously free of dengue fever., Methods: Routine surveillance confirmed locally acquired cases in the second week of December, leading to a rapid public health response including case management guidance and epidemiological investigations. The main activity was the vector survey using systematic sampling to assess extent of previously unreported Aedes aegypti presence followed by a campaign aimed to eliminate breeding sites of A. aegypti"., Results: During a 5-month period, 343 suspected cases were reported from Muscat Governorate with 122 from the outbreak affected area. Out of 207 probable cases eligible for laboratory testing as per guidelines issued, 59 cases were confirmed. The vector elimination campaign started on January 8, 2019 after a media advocacy using television and social media and concluded on January 23. By the end of campaign, the case load had decreased significantly in the affected area with no reports of locally acquired cases from adjoining areas of Muscat Governorate, indicating no further spread., Conclusions: Rapid notification and early community-wide, extensive vector control activities effectively contained the autochthonous dengue fever virus outbreak., (Copyright © 2019 The Author(s).

- Abstract
Despite the advances in the management of thalassemia major, heart disease remains the leading cause of mortality in patients afflicted with this disorder. Cardiac involvement in thalassemia encompasses a spectrum of disorders including myocardial dysfunction, arrhythmias, pulmonary hypertension, and peripheral vascular disease. Although cardiac siderosis (accumulation of iron in cardiac myocytes) as a consequence of repeated blood transfusions is deemed to be the main etiologic factor for myocardial dysfunction in transfusion-dependent patients, the significance of other pathophysiologic mechanisms is being increasingly recognized especially in non-transfusion dependent patients. Management of cardiac complications in thalassemia major hinges on the treatment of the underlying pathophysiology, which often is unmitigated iron overload. The prevalence and predictors of cardiac complications in 'ex-thalassaemics' [thalassaemic patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) is unknown at present. In this review, we look at the pathogenesis of cardiac involvement in patients with beta-thalassemia major, the advances in the management of these patients and the future prospects.

- Abstract
Background: Crimean-Congo hemorrhagic fever (CCHF) is a serious disease with a high fatality rate reported in many countries. The first case of CCHF in Oman was detected in 1995 and serosurveys have suggested widespread infection of humans and livestock throughout the country., Methodology: Cases of CCHF reported to the Ministry of Health (MoH) of Oman between 1995 and 2017 were retrospectively reviewed. Diagnosis was confirmed by serology and/or molecular tests in Oman. Stored RNA from recent cases was studied by sequencing the complete open reading frame (ORF) of the viral S segment at Public Health England, enabling phylogenetic comparisons to be made with other S segments of strains obtained from the region., Findings: Of 88 cases of CCHF, 4 were sporadic in 1995 and 1996, then none were detected until 2011. From 2011-2017, incidence has steadily increased and 19 (23.8%) of 80 cases clustered around Eid Al Adha. The median (range) age was 33 (15-68) years and 79 (90%) were male. The major risk for infection was contact with animals and/or butchering in 73/88 (83%) and only one case was related to tick bites alone. Severe cases were over-represented: 64 (72.7%) had a platelet count < 50 x 109/L and 32 (36.4%) died. There was no intrafamilial spread or healthcare-associated infection. The viral S segments from 11 patients presenting in 2013 and 2014 were all grouped in Asia 1 (IV) lineage., Conclusions: CCHF is well-established throughout Oman, with a single strain of virus present for at least 20 years. Most patients are men involved in animal husbandry and butchery. The high mortality suggests that there is substantial under-diagnosis of milder cases. Preventive measures have been introduced to reduce risks of transmission to animal handlers and butchers and to maintain safety in healthcare settings., Competing Interests: The authors have declared that no competing interests exist.
