Prevalence of Hepatitis B Infection Among Pregnant Women in Oman.

OBJECTIVE: The primary objective of our study was to estimate the prevalence of hepatitis B infection among pregnant women in Oman. The secondary objectives were to test for other hepatitis B virus (HBV) serological markers and to determine hepatitis B viral load. METHODS: In this cross-sectional study conducted from June 2019 to December 2020, we randomly selected 2210 Omani women who attended antenatal clinics across the country. Pregnant women were tested for HBV surface antigen (HBsAg) using a commercial enzyme immunoassay; those who tested positive were further analyzed for other HBV serological markers: HBV core total antibody (anti-HBc), HBV core antibody IgM (immunoglobulin M) (anti-HBc IgM), hepatitis B virus e antigen (HBeAg) and hepatitis B virus e antibody (anti-HBe). They were also tested for hepatitis B viral load. RESULTS: This study included 2210 women with a mean age of 39 years. Ninety-five percent of the women who were invited to participate consented and were included in the study. Thirty-three (1.49%) tested positive for HBsAg. All participants tested negative for HBeAg and anti-HBc IgM and positive for anti-HBc and anti-HBe, and 30 (90.9%) women had their hepatitis B viral load measured. Three (10.0%) had undetectable viral loads, 23 (76.7%) had low viral loads of < 2000 (IU/ml), 2 had moderate viral loads between 2000 and 200,000 (IU/ml) and one had a high viral load of 486,000 (IU/ml). CONCLUSION: Our study shows that the HBV prevalence in pregnant women is 1.49%, which is lower than what was reported earlier. Nevertheless, antenatal screening is still warranted, as there are vital interventions for the newborn and the mother.

Reporting at Least One Adverse Effect Post-COVID-19 Vaccination From Primary Health Care in Muscat.

Introduction Vaccinations against COVID-19 were licensed with limited testing assurances to the public triggering a widespread hesitancy around expected adverse reactions. Limited data was reported from Arabian Gulf countries on vaccine adverse effects. Objectives This study looked at the rate of reporting at least one side effect post-COVID-19 vaccination and its associated factors (sociodemographic characteristics, clinical condition, and type of vaccines). Additionally, questions about safety and willingness to recommend them were included. Study design Phone interviews on post-COVID-19 vaccination adverse effects were utilized to record responses related to reporting at least one side effect post vaccinations across the studied variables. Data collection continued for two months (from 1st March to 30th April 2021). Methodology Participants were adults (Omani citizens and non-citizens) who received AstraZeneca (AZ) or Pfizer (PF) vaccines from primary care facilities in Muscat and were randomly selected from the health information system. Responses were saved in a bespoke Google form/questionnaire. Chi-squared tests were utilized to determine potential factors associated with the dependent variable. Results A total of 753 participants completed the phone interviews. The mean age was 52 (3.5), males (54.1%), and 65.1% were Omanis. Hypertension (39.7%), diabetes (34.1%), and asthma (16.7%) were the commonest comorbidities. AZ and PF were administered to 78% and 22% of the participants. Of them, 49.8% reported at least one adverse effect post-COVID-19 vaccination. The proportion of participants with at least one adverse effect was significantly more in individuals who were younger, females, with more than secondary education, and employed (p value < 0.001, 0.01, <0.001, and <0.001, respectively). There was no severe reaction (anaphylactic shock) to the vaccines, and most adverse effects were mild-moderate. The proportion of individuals who reported adverse effects were higher with AZ vs PF (53% vs 38.6, p = 0.001). The most common reported localized adverse effects were pain and tenderness (28.3% and 12.1%). Fever and body aches were the commonly reported systemic adverse effects (33.5% and 29.2%). The safety of COVID-19 vaccines was well perceived, and most participants were willing to recommend them to others. Conclusions The current study confirms findings from existing literature on the mild to moderate adverse effects of AZ and PF vaccines. Despite the subjective nature of this study, it is reassuring that the studied COVID-19 vaccines can be administered safely. However, more longitudinal studies are needed to test their efficacy in disease prevention.

Elimination of mother-to-child transmission of HIV in Oman: a success story from the Middle East.

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.

The characteristics and patterns of utilization of healthcare services among Omanis with substance use disorders attending therapy for cessation.

BACKGROUND: It is indicated that Oman is witnessing an increase in issues pertinent to alcohol and psychoactive substance use. AIM: The aim of this study was to identify the characteristics of Omanis with substance use disorder attending a specialized hospital in Oman and the pattern of their utilization of healthcare services. A related aim was to ascertain the age group most vulnerable to alcohol and substance use in Oman. METHOD: A cross-sectional study was conducted in a tertiary care center specialized for treatment of those engaging in substance use in Oman. The participants in the study were selected from a convenience sample among patients seeking consultation at the center for alcohol and substance use. A six-part questionnaire was designed to obtain information regarding socio-demographic background, clinical history, healthcare utilization and perceived hurdles to access. Chi-square analyses were used to evaluate the significance of differences among categorical data. Logistic regression modelling was used to obtain measures of association after adjusting for confounding factors. RESULTS: Among the patients (n = 293) seeking cessation therapy, 99% were male and less than 30 years of age. Peer influences on the initiation of substance use were significant. Most patients had a history of polysubstance use, including intravenous substance use. Cannabis and alcohol were the first substances consumed by most patients and Hepatitis C and psychiatric disorders were found to be the most common co-morbidities. The participants that reported use of cannabis and benzodiazepines were more likely to perceive "improvement" upon receiving treatment. CONCLUSION: This study indicated that males below 30 years of age with a history of polysubstance use were likely to attend a hospital specialized in treating substance use disorder in Oman. This study identified information regarding socio-demographic background, risk factors and perceived hurdles to healthcare that could serve as groundwork for further studies conducted on newly emerging issues of substance use in Oman.

Outcomes of selective nonoperative management of civilian abdominal gunshot wounds: a systematic review and meta-analysis.

Background: Although mandatory laparotomy has been standard of care for patients with abdominal gunshot wounds (GSWs) for decades, this approach is associated with non-therapeutic operations, morbidity, and long hospital stays. This systematic review and meta-analysis sought to summarize outcomes of selective nonoperative management (SNOM) of civilian abdominal GSWs. Methods: We searched electronic databases (March 1966-April 1, 2017) and reference lists of articles included in the systematic review for studies reporting outcomes of SNOM of civilian abdominal GSWs. We meta-analyzed the associated risks of SNOM-related failure (defined as laparotomy during hospital admission), mortality, and morbidity across included studies using DerSimonian and Laird random-effects models. Between-study heterogeneity was assessed by calculating I2 statistics and conducting tests of homogeneity. Results: Of 7155 citations identified, we included 41 studies [n = 22,847 patients with abdominal GSWs, of whom 6777 (29.7%) underwent SNOM]. The pooled risk of failure of SNOM in hemodynamically stable patients without a reduced level of consciousness or signs of peritonitis was 7.0% [95% confidence interval (CI) = 3.9-10.1%; I2 = 92.6%, homogeneity p < 0.001] while the pooled mortality associated with use of SNOM in this patient population was 0.4% (95% CI = 0.2-0.6%; I2 = 0%, homogeneity p > 0.99). In patients who failed SNOM, the pooled estimate of the risk of therapeutic laparotomy was 68.0% (95% CI = 58.3-77.7%; I2 = 91.5%; homogeneity p < 0.001). Risks of failure of SNOM were lowest in studies that evaluated patients with right thoracoabdomen (3.4%; 95% CI = 0-7.0%; I2 = 0%; homogeneity p = 0.45), flank (7.0%; 95% CI = 3.9-10.1%), and back (3.1%; 95% CI = 0-6.5%) GSWs and highest in those that evaluated patients with anterior abdomen (13.2%; 95% CI = 6.3-20.1%) GSWs. In patients who underwent mandatory abdominopelvic computed tomography (CT), the pooled risk of failure was 4.1% versus 8.3% in those who underwent selective CT (p = 0.08). The overall sample-size-weighted mean hospital length of stay among patients who underwent SNOM was 6 days versus 10 days if they failed SNOM or developed an in-hospital complication. Conclusions: SNOM of abdominal GSWs is safe when conducted in hemodynamically stable patients without a reduced level of consciousness or signs of peritonitis. Failure of SNOM may be lower in patients with GSWs to the back, flank, or right thoracoabdomen and be decreased by mandatory use of abdominopelvic CT scans.

Prospective study on prevalence and risk factors of postpartum depression in Al-dakhliya governorate in oman.

OBJECTIVES: Postnatal Depression (PND) is a major health problem. It has a serious impact on the mother, her child and family. Studies have shown wide diversity of its prevalence across different cultures. Its epidemiology and its associated risk factors in Oman remain unknown. The objectives of this study were to estimate the prevalence of PND in the Al-Dakhliya governorate and to identify the risk factors contributing to the development of PND. METHODS: A total of 282 Omani women who gave birth in September 2010 were part of a prospective study conducted in Al-Dakhliya governorate. An Arabic version of the Edinburgh Postnatal Depression Scale (EPDS) was used to assess the PND symptoms. Negative binomial regression model was used to identify the independent predictors of outcome (EPDS scores at two and eight weeks post-delivery) due to the non-normal distribution of the EPDS scores. RESULTS: The study results showed that at two weeks, 13.5% of mothers and 10.6% at eight weeks had EPDS scores of 13. Bahla district was found to have the highest number of depression scores among the other six districts in the governorate. It was found that mothers less than 25 years of age were more likely to report high EPDS scores. The independent predictor was work difficulties both at two and eight weeks postpartum (p=0.001 and p=0.019, respectively). At two weeks postpartum, significant association was also found between depression scores and conflict with a family member (p=0.017), and sickness of a family member (p=0.010). There was no significant association between EPDS scores and socio-demographic, obstetric or other clinical factors. CONCLUSION: This study is among the few studies looking at PND in the Middle East and shows on average 12% of Omani women are at a high risk of developing PND (EPDS scores of ≥13). Although the study findings were based on an unvalidated version of EPDS for Omani women, they can be used as a basis for further research.
