Association of the Magnitude of Anti-SARS-CoV-2 Vaccine Side Effects with Sex, Allergy History, Chronic Diseases, Medication Intake, and SARS-CoV-2 Infection

Vaccination provides the best protection against the increasing infections of SARS-CoV-2. The magnitude and type of anti-SARS-CoV-2 vaccine side effects (SEs) depend on parameters that are not fully understood. In this cross-sectional study, the associations between different anti-SARS-CoV-2 vaccine SEs and age, sex, the presence of chronic diseases, medication intake, history of allergies, and infections with SARS-CoV-2 were investigated. Our survey used the Google platform and had 866 participants, contacted through e-mails, social media and chain referral sampling (margin of error ≈ 4.38%, 99% confidence). More than 99% of the participants received the BNT162b2 and ChAdOx1-S vaccines. Being female, having chronic diseases, taking medicines routinely and the presence of a SARS-CoV-2 infection (p < 0.05) were associated with strong SEs after the BNT162b2 vaccine second dose. Having a history of allergies and a female sex (p < 0.01) were associated with strong SEs after the ChAdOx1-S vaccine second dose. Furthermore, the results reveal, for the first time, the associations between having a history of allergies, chronic diseases, medication usage, and SEs of a strong magnitude for the BNT162b2 and ChAdOx1-S vaccines. Additionally, this study supports the association of the female sex and infection with SARS-CoV-2 with an increased potential of developing stronger SEs with certain anti-SARS-CoV-2 vaccines.

Effects of a Healthy Diet on Reducing Symptoms of Premenstrual Syndrome and Improving Quality of Life among Omani Adolescents: A Randomized Controlled Open-Label Trial

Premenstrual syndrome (PMS) continues to impact the health outcomes and emotional well-being of reproductive-age women, globally. Several studies have provided conflicting evidence concerning the role of dietary approaches in improving PMS symptoms. Accordingly, this study aimed to evaluate the possible influence of a healthy diet and motivational strategies on PMS symptoms and health-related quality of life among Omani adolescents. This open-label, randomized, prospective controlled trial was conducted at two randomly selected secondary schools, in Al Seeb Willayah, in Muscat region. Adolescents with PMS symptoms, who were in grade 10 or 11, aged 16 years or above, had regular menstrual cycles, and were not known to have psychiatric disorder were included in this study. Participants in the intervention group received an individual face-to-face dietary consultation and motivational phone consultation. The health outcomes, including the PMS symptoms in both groups, and quality of life, were recorded using the Daily Record of Severity of Problems questionnaire (DRSP) and the 14-item Self-Reporting-Based Perceived Stress Scale tools, respectively. The primary outcome was the difference in the mean premenstrual symptom scores between the two groups. Secondary outcomes included the quality of life and stress levels of participants. The study period was from 1 February and ended 30 June 2021. SPSS was used to analyze the data, and intention-to-treat analysis was utilized. A total of 72 adolescents with PMS were randomized into intervention and control groups (n = 36 each). Both groups were similar at baseline (p-value > 0.05). No significant association was found between a healthy diet and PMS symptoms (p-value > 0.05). In addition, no significant association was found between a healthy diet and quality of life at follow-up (p-value = 0.216). The outcomes of this study refuted any possible relationships between a healthy diet and PMS symptoms. Accordingly, dietary consultations may not facilitate the clinical management of PMS symptoms in adolescent females.

The Practice of Prescribing Antidepressants During Pregnancy and Breastfeeding Among Mental Health Practitioners in Tertiary Care Centers in Oman

Objectives

This study sought to determine the confidence level of mental health practitioners in Oman regarding the use of antidepressants during pregnancy and breastfeeding, assess their knowledge and need for further training in this area, and examine their current prescribing patterns and preferences.

Methods

A questionnaire-based survey was conducted from May to June 2017 among all practitioners in the psychiatry specialty, including medical officers authorized to prescribe medications, at the Behavioral Medicine Department of Sultan Qaboos University Hospital and Al Masarra Hospital.

Results

Forty-two practitioners (response rate = 89.4%) responded to the questionnaire. Of them, 10 (23.8%) had no experience, while 30 (71.4%) had experience in prescribing antidepressants during both pregnancy and breastfeeding periods. Twenty-seven (64.3%) respondents felt that they were confident in prescribing antidepressants for women during their perinatal period, while 30.0% were neutral. Moreover, 35 (83.3%) participants expressed the need for more training in this area. Furthermore, 34 (81.0%) believed that more training in perinatal psychiatry should be included in the psychiatry curriculum. There was no consistent prescribing pattern (either prescribing or avoiding) among our participating practitioners during the first trimester of pregnancy and breastfeeding periods. The drug of choice in the first trimester of pregnancy was fluoxetine preferred by approximately 85.0% of the practitioners, but avoided by 10.0% of practitioners in the same period. This was followed by amitriptyline (50.0% vs. 23.0%), sertraline (50.0% vs. 9.0%), imipramine (28.0% vs. 84.0%). During breastfeeding, the drug of choice for approximately 74.0% of the practitioners was paroxetine, but avoided by 15.0% of practitioners. This was followed by sertraline (50.0% vs. 8.0%). The most common reasons for prescription during pregnancy were safety, evidence-based practice, and low teratogenicity. For breastfeeding, the main reasons for prescription were low levels of the drug in breast milk, safety, and evidence-based practice. On the other hand, high teratogenicity, neonatal side effects, limited data, and lack of evidence were among the most common reasons behind avoiding prescribing during pregnancy, while high levels of breast milk, neonatal side effects, limited evidence, and safety concerns were the most common reasons during the breastfeeding period.

Conclusions

There was inconsistency among mental health practitioners in making prescription decisions and in their prescribing patterns.

Perceptions of Undergraduate Medical Students Toward Integrated Management of Childhood Illness (IMCI) Pre-service Education at Sultan Qaboos University, Muscat

Background Inconsistent evidence concerning the clinical practice implications of the Integrated Management of Childhood Illness (IMCI) pre-service education exists in the literature. The aim of this study is to assess the IMCI pre-service training perceptions of medical students, including their willingness to prospectively utilize the IMCI guidelines in clinical settings. Methods This is an observational cross-sectional study that was conducted between June 1 and August 31, 2022, at the College of Medicine and Health Sciences, Sultan Qaboos University (SQU), Muscat, Sultanate of Oman. The demographic data and IMCI pre-service education perceptions were recorded via the 10 close-ended questions. The questions focused on the student's perception of the usefulness of IMCI pre-service training in improving their knowledge, attitude, and practice (KAP) regarding childhood illnesses and how well it has enhanced their skills in dealing with sick children. SPSS Statistics version 26.0 (IBM Corp. Released 2019. IBM SPSS Statistics for Windows, Version 26.0. Armonk, NY: IBM Corp.) was used to analyze the data. Results A total of 196 responses were collected, with 117 of them being from female participants and the remaining 79 from male participants. Participants were subcategorized into phase 2 (n=103), phase 3A (pre-clerkship, n=45), and phase 3B (junior clerkship, n=48). At least 67.8% of 171 medical students complying with one to two training sessions intended to apply their IMCI pre-service education knowledge and skills in clinical practice and parental counseling. The medical knowledge and clinical practice skill enhancement abilities of the IMCI sessions were recognized by ≥49.7% of medical students. The student responses regarding childhood illness management (p=0.03) and holistic assessment confidence (p=0.042) varied significantly between the study phases. The IMCI pre-service skills, knowledge, and confidence levels were observed in 47.1% (phase 2), 13.2% (phase 3A), and 35.5% (phase 3B) of medical students. Similarly, 40.2% (phase 2), 23.7% (phase 3A), and 54.8% (phase 3B) of subjects believed in the IMCI pre-service training's influence on their ability to perform holistic assessments in the pediatric population. Conclusion The overall results of this study advocate the clinical practice implications, based on the positive student perceptions, of the IMCI pre-service training in SQU. Future qualitative studies should evaluate these findings with wider student populations.

Prevalence of Urinary Incontinence and its Relationship With Sociodemographic and Obstetrical Variables Among Omani Women

Objective

Urinary incontinence (UI) is defined by the International Continence Society as any complaint of involuntary urine leakage. This research study highlights the prevalence, types, and associated factors of UI among women in Oman.

Methodology

A descriptive cross-sectional design was used to collect data using purposive sampling technique from 400 women between 20 and 60 years; who were attending outpatient department of a referral hospital in Oman. Women were assessed using the Questionnaire for Urinary Incontinence Diagnosis to determine the type of UI. The severity and the impact of UI in women were assessed using the female urinary tract symptoms module (ICIQ-UI-SF). Descriptive statistics were used to determine the prevalence and type of UI, and the Chi-square test was used to find the association between UI and sociodemographic and obstetrical variables.

Results

In our study, 28.25% of the women belonged to the age of 50-59 years. The point prevalence (per 1000) of UI among Omani women who were between 20 and 60 years was 44%. In the women who had UI, the majority were having stress UI (41.6%). In the women who had UI, the severity of UI, according to the ICIQ-UI-SF scoring, 15.2% of the women had slight, 50.3% had moderate, 33.1% had severe, and only 1.3% had very intense.

Conclusion

Understanding the prevalence of UI in every community and associated factors is essential for the policy makers and healthcare providers to consider the early diagnosis, prevention, health promotion, and management of UI.

The Assessment of Immediate Postoperative Delirium in Neurologically Intact Adult Patients Admitted to the Post-anesthesia Care Unit: A Cross-Sectional Study

Background

Immediate postoperative delirium (IPD) in the post-anesthesia care unit (PACU) can cause significant morbidity affecting everyday activities and length of stay with cost implications. This study was undertaken to find the proportion of IPD in PACU and its association with anesthesia and other perioperative factors.

Methods

After obtaining ethical approval and informed consent, this cross-sectional study was conducted in the PACU. A total of 600 consecutive adult patients (American Society of Anesthesiologists (ASA) 1-3) posted for surgery were approached between January and March 2019, of which 402 patients without neurological diseases and language and hearing discrepancies were studied. All patients had the intervention of surgery under anesthesia in a usual manner. Delirium was assessed preoperatively, postoperatively at 15 and 30 minutes, and before discharge from the PACU. IPD was assessed using the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) score, while sedation/agitation was assessed using the Richmond Agitation-Sedation Scale (RASS). The primary outcomes were the proportion of IPD, association with anesthesia, and perioperative risk factors. The secondary outcomes were the length of stay, delirium treatment, and mortality.

Results

Overall, the IPD proportion was 14.7%. A significant association was demonstrated with premedication with midazolam (odds ration (OR): 3.2; 95% confidence interval (CI): 1.42-7.35; P=0.003), general anesthesia (GA) (OR: 6.3; 95% CI: 2.23-17.8; P<0.001), duration of anesthesia (126 versus 95 minutes; P=0.001), laparoscopic mode of surgical access (OR: 3.4; 95% CI: 1.8-6.4; P<0.001), and postoperative RASS >/< 0 (OR: 10.6; 95% CI: 4.69-24.11; P<0.001) at 30 minutes and before discharge from the PACU. Multivariate analysis showed the strongest association of RASS at 30 minutes with IPD.

Conclusion

The proportion of IPD was found to be 14.7% in this study, and the chances of developing IPD are high if the patient is not awake and calm in the PACU, especially if midazolam is administered as premedication, followed by general anesthesia (GA) for a long duration.

Age of Transition Readiness of Adolescents and Young Adults With Chronic Diseases in Oman: Need an Urgent Revisit

BACKGROUND

The Ministry of Health in Oman and some of Gulf regions set the cut-off age of "transfer" from child health care to adult health care at 13 years of age. Within the existing health system in this part of the world, there is paucity of evidence on the appropriate age for health care "transfer" of adolescents and young adults to adult health care. Similarly, there is lack of a structured health care "transition" program. The objective of the study is to indirectly determine the appropriateness of present cut-off age of transfer by studying readiness for transition among Omani patients suffering from chronic hematological conditions.

METHODS

One hundred fifty adolescents and young adults with chronic hematological conditions were recruited from pediatric and adults clinics at Sultan Qaboos University Hospital. Participants were interviewed by a trained research assistant using the Arabic version of UNC TRxANSITION Scale to assess self-management skills and health related knowledge for transition. The score range is 0 to 10; the transition readiness of the patients is assessed as low (0 to 4), moderate (4 to 6), and high (6 to 10) respectively. The continuous variables were analyzed by parametric or nonparametric methods as appropriate. χ2 analysis was done to determine association of age groups within each sexes.

RESULTS

The study recruited 150 subjects (52.7% males) with 50 patients in each of the 3 age groups of 10 to 13 years (lower), 14 to 17 years (middle), and 18 to 21years (higher). The mean UNC TRxANSITION Scale scores of 5.14 (SD=1.27) in males in the total sample were significantly lower as compared with that of 5.67 (SD=1.50) in females (P=0.022). There is a steady increase in the overall median score with increase in age group, with median score of 4.42 in the lower, 5.26 in the middle and 6.81 in the higher age group (P<0.001). In section wise analysis, except for Adherence and Nutrition sections of the scale, all sections have statistically significant difference in the median scores across various age categories with lowest scores in the 10 to 13 age group and highest scores in the 18 to 21 years group. In the section related to reproduction, females had significantly higher mean ranks (31.52) and compared with 17.19 in males (P=0.001). The overall median transition score when analyzed separately for males and females across age groups showed that in the higher age group, 67% of males (P=0.008) and 90% females (P<0.001) have high transition scores compared with the other 2 groups.

CONCLUSIONS

Higher age was a significant predictor for transition readiness with median score being "moderate" in the lower and middle age groups, while the higher age groups scoring "high" on transition readiness. However, in the higher age group, the females (90%) showed better transition readiness than males (67%). The current age of transfer of 13 years is just at "moderate" levels. We recommend the need for establishing transition preparation program in Oman; increasing health transfer age in Oman to a cut-off age of 18 years and taking sex differences into consideration when providing interventions.

Depression in Urban Omani Adults with Type 2 Diabetes

Objectives

This study aimed to identify the prevalence of clinically significant depression among adult Omani patients with type 2 diabetes mellitus (T2DM) and explore potential associations with sociodemographic and clinical variables in this population.

Methods

This descriptive cross-sectional study was conducted between August 2018 and September 2019 and included 427 Omani T2DM patients from 12 randomly selected government health centres in Muscat, Oman. An Arabic version of the validated Patient Health Questionnaire-9 was administered to the participants via face-to-face interviews to determine the prevalence of depression.

Results

A total of 111 T2DM patients (response rate: 100%) had depression (26%). The presence of a personal history of depression was the only variable significantly associated with depression (P <0.001). Other sociodemographic and clinical factors including age, gender, duration of diabetes, glycated haemoglobin level, mode of diabetes treatment or the presence of diabetes-related complications such as cardiac complications, renal impairment, retinopathy, neuropathy and erectile dysfunction, were not associated with depression, (P >0.050 each).

Conclusion

This study revealed a high prevalence of depression among urban Omani adults with T2DM and a personal history of depression, which was found to be significantly associated with depression. Therefore, early screening for depressive symptoms is necessary to improve the quality of life of diabetic patients in this region.

Risk Factors for Ischaemic Stroke in an Omani Community: A case-control study

Objectives

Stroke is recognised as the third most common cause of mortality and it has an increasing incidence in developing countries. Recognition and control of risk factors are of prime importance in the prevention of stroke. This study aimed to examine the characteristics of ischaemic stroke (IS) patients in Oman and quantify its various risk factors using a case-control model.

Methods

This case-control study was conducted from January 2012 to March 2013 at Sultan Qaboos University Hospital and Royal Hospital, Muscat. Adult Omani patients with IS who were admitted to either hospital were compared to age- and gender-matched controls. Demographic factors and frequency of various conventional risk factors were documented. Univariate and stepwise multivariate logistic regression analyses were performed to evaluate the risk factors associated with IS.

Results

A total of 255 patients and age-and gender-matched controls were included in this study. The mean age was 62.2 ± 13.2 years and 63.14% were male. Most cases (89.02%) were above 45 years of age. Cardio-embolism (31.76%) was the commonest mechanism of IS. Stepwise multiple logistic regression model revealed that family history of stroke was the strongest independent risk factor, followed by hypertension and high-density lipoprotein levels (odds ratio: 10.10, 5.17 and 3.34, respectively; P <0.01 each).

Conclusion

Cardio-embolism was the predominant mechanism of IS in this study. Family history of stroke, hypertension and reduced high-density lipoprotein were the leading independent risk factors. Strong emphasis on screening for risk factors, control of hypertension and lifestyle modification for those with a family history of stroke would be expected to emerge as the major stroke-preventive measures in Oman.

The Unmet Supportive Care Needs of Omani Women Diagnosed with Breast Cancer

Objectives: This study aimed to assess the unmet supportive care needs of Omani women with breast cancer (BC). Methods: This cross-sectional study was conducted from November 2020 to February 2021 among 250 adult Omani women diagnosed with BC at a university teaching hospital in Muscat, Oman. An Arabic version of the 34-item Supportive Care Needs Survey-Short Form tool was used to determine perceived unmet supportive care needs across five domains. Results: A total of 181 women participated in the study (response rate: 72.4%). The domain with the highest mean score per item was health system and information (mean score: 3.33), with the greatest unmet need in this domain being informed about things that the patient could do to help themselves get well (40.9%). The domain with the second highest mean score per item was patient care and support (mean score: 3.04), with the greatest unmet need being for clinicians to be more sincere with the patient (36.5%). Higher total mean scores were reported by women who had visited the hospital four times or more over the past two months (P = 0.045), those with stage 3 or 4 cancer (P = 0.047) and those who had recently undergone radiotherapy or chemotherapy (P = 0.014). Conclusion: Most unmet supportive care needs fell under the health system and information domain. Healthcare providers in Oman should explore patient concerns and provide sufficient information at various stages of the care process in order to decrease the anxiety associated with living with cancer. Keywords: Breast Neoplasms; Needs Assessment; Supportive Care; Women; Oman.

Radiologic evaluation of congenital anomalies of anterior and posterior arch of atlas in Omani subjects

The atlas (C1) is known to present congenital anomalies in its anterior and posterior arches. The reported incidence of C1 anomalies is varied among the ethnic groups. We sought to determine the prevalence and various existing variations of C1 arch congenital anomalies in Omani subjects. This study was carried out by reviewing the cervical spine computed tomography scans of all the patients who had been referred to the Radiology Department, Sultan Qaboos University Hospital. Descriptive statistics and chi-square test were employed to analyse the data. A total of 663 subjects aged ≥18 years were included in the present study. Overall prevalence of C1 arch anomalies was 4.37% with 4.07% of isolated posterior arch anomalies, 0.3% of combined anterior and posterior arch anomalies. Among isolated posterior arch anomalies, type A and type B posterior arch defects were found in 3.77% and 0.3% of cases, respectively. Atlanto-occipital assimilation was noted in one case of total study subjects. The prevalence rate of C1 arch anomalies is relatively high in Omani subjects. The baseline data of C1 arch anomalies reported in the present study has a great impact on clinical practice, due to the fact that studying and evaluating the types of congenital anomalies helps in their accurate diagnosis and early intervention.

Short-Term Outcomes of Atosiban in the Treatment of Preterm Labour at the Sultan Qaboos University Hospital, Muscat, Oman: A tertiary care experience

Objectives

This study aimed to generate baseline evidence regarding the effectiveness of atosiban in delaying delivery by ≥48 hours among pregnant women presenting with threatened preterm labour (TPL). The secondary objective was to assess the relationship between atosiban success and various perinatal factors and neonatal outcomes.

Methods

This retrospective study was conducted between June 2008 and May 2018 at the Sultan Qaboos University Hospital, Muscat, Oman. The medical records of all pregnant women who received atosiban between 24–34 gestational weeks for TPL during this period were reviewed.

Results

A total of 159 women were included in the study. Atosiban was successful in delaying delivery by ≥48 hours in 130 cases (81.8%). Approximately half of the women (50.9%) achieved uterine quiescence in <12 hours. Failure to delay delivery by ≥48 hours was significantly lower among women with normal versus abnormal cervical findings (11.1% versus 25.6%; P = 0.023). Only 9.4% of women experienced minor side-effects. Mean birth weight (2,724.55 versus 1,707.59 g; P <0.001) and Apgar scores at 5 minutes (9.66 versus 8.28; P <0.001) were significantly higher among neonates delivered at ≥48 versus <48 hours post-atosiban, whereas the rate of neonatal respiratory distress syndrome was significantly lower (18.4% versus 81.6%; P <0.001).

Conclusion

Atosiban was highly effective in delaying delivery by ≥48 hours and resulted in few adverse maternal side-effects and neonatal outcomes. To the best of the authors’ knowledge, this is the first study conducted in Oman to evaluate the effectiveness of atosiban in preventing preterm labour.

Defining IL-6 levels in healthy individuals: A meta-analysis

BACKGROUND

Interleukin-6 (IL-6) is produced by and impacts different cell types in human. IL-6 is associated with different diseases and viral infections, including COVID-19. To our knowledge, no normal values were reported for IL-6 in the blood of healthy individuals. We have reviewed and performed a meta-analysis on a total of 140 studies, including 12,421 values for IL-6 in the blood of healthy adult donors. Among these studies, 83 did not report a mean value and the standard deviation. Therefore, for the statistical analysis, we used the values reported in 57 studies, which included 3166 values for IL-6.

RESULTS

The reported values for IL-6 in the blood of healthy donors varied between 0 and 43.5 pg/ml. The pooled estimate of IL-6 was 5.186 pg/ml (95% confidence interval [CI]: 4.631, 5.740). As the age increased by 1 year, IL-6 values increased by 0.05 pg/ml (95% CI: 0.02, 0.09; p < .01). Though the heterogenicity, as determined by I2 statistics, was high in our study, the differences in IL-6 values are still at the level of a few pg/ml, which might be related to the differences in the conditions that influence IL-6 production in the healthy population.

CONCLUSIONS

This is the first meta-analysis reporting the levels of IL-6 in the blood of healthy donors based on a large number of studies and donors. Therefore the 95% CI values determined in our study could well serve as a reference range for quick decision-making in clinical interventions, particularly those aiming to inhibit IL-6, especially urgent interventions, for example, COVID-19.

Radiological study of fabella in Omani subjects at a tertiary care center

Ethnic diversity is associated with variability in the prevalence rates of fabella. We aimed to evaluate the prevalence and the radiological features of fabella in Omani patients. This is a retrospective analysis of hospital electronic database of patients referred for radiological investigations (radiographs and magnetic resonance imaging) of the knee, at a tertiary care referral center. Descriptive statistics were performed to determine the prevalence of fabella. Chi-square test was used to determine the association between sex or age with respect to the presence of fabella. A total of 813 knee radiographs were reviewed for the presence of fabella. Fabella was found in 24.1% of total cases. A statistically significant sex difference was observed with respect to the presence of fabella in left knees in males (P<0.01). The presence of fabella was significantly associated with age groups for the right (P<0.05) and left knees (P<0.01). In magnetic resonance imaging film reviews, all the identified fabellae (20.2%) were bony structures and were located within the lateral head of the gastrocnemius muscle. There were no cartilaginous fabellae detected. The current study revealed a prevalence of 24.1% of fabella in Omani subjects which is almost similar to the results as seen in Caucasian ethnic populations.

Prevalence and distribution of sesamoid bones of the hand in Omani subjects: a radiological study

Sesamoid bones show considerable variations in their occurrence among various ethnicities. This study aims to evaluate the prevalence and distribution patterns of the sesamoid bones of the hands among Omani patients who were referred for radiological investigations. The influence of gender and different age groups on the occurrence of sesamoid bones of the hand was determined using the Chi-square test. Spearman's rank correlation was used to determine the coexistence of sesamoid bones at the metacarpophalangeal joints. A total of 541 hand radiographs were reviewed. A high prevalence of sesamoid bones at the fifth metacarpophalangeal joint and the interphalangeal joint of the thumb was noted with a frequency of 64% and 49.7%, respectively. There were ten different patterns of sesamoid bones detected, the most common of which was the presence of sesamoid bones at the first and fifth metacarpophalangeal joints found in 32.9% of the radiographs. A statistically significant gender difference was observed at the interphalangeal joint of the thumb (p = 0.025) and fifth metacarpophalangeal joint (p = 0.027) with a female dominance. A significant association between the age and prevalence of sesamoid bones was noted at the fifth metacarpophalangeal joint (p = 0.03). The prevalence of the sesamoid bones of the hand in Omani subjects seems to differ from other Middle Eastern populations, particularly at the fifth metacarpophalangeal joint and the interphalangeal joint of the thumb. In the meantime, the baseline data of our study can be helpful while treating the patients complaining of hand discomfort or pain.

Radiological Study on Sesamoid Bones of the Foot among Omani Subjects

Objectives

The prevalence and appearance of sesamoid bones in the foot vary considerably among different populations and ethnic groups. We sought to evaluate the prevalence and distribution patterns of foot sesamoid bones among Omani patients referred for radiological investigation.

Methods

We conducted a retrospective study among patients who had been referred for foot X-ray from January to December 2018. We used the chi-square test to determine the gender and age influence on the prevalence of sesamoid bones, and the Spearman’s correlation coefficient to assess the coincidence of specific distributions of sesamoid bones at the metatarsophalangeal (MTP) joints.

Results

A total of 774 foot radiographs composed of 442 right foot radiographs and 332 left foot radiographs were reviewed for the presence of sesamoid bones at MTP and interphalangeal (IP) joints of the foot. We observed a high prevalence rate of sesamoid bones at the fifth MTP joint (13.7%), and first IP of the great toe (9.9%). There were nine distinctive patterns of sesamoid bones. The coincidence of sesamoid bones at two or more MTP joints was 14.6%, with a high prevalence rate at first and fifth MTP joints (10.3%). Moreover, the prevalence rate of sesamoid bones increased with increasing age at the fifth MTP joint.

Conclusions

The prevalence of sesamoid bones in the foot is considerably high in Omani subjects and needs further prospective studies. Meanwhile, our findings could be helpful for clinicians to consider ailments of sesamoid bones during differential diagnosis in Omani patients who present with foot pain and discomfort.

Respiratory Distress Syndrome in Neonates Delivered at Term-gestation by Elective Cesarean Section at Tertiary Care Hospital in Oman

Objectives

We sought to assess the relationship between respiratory distress syndrome (RDS) in neonates delivered by elective cesarean section at term gestation with and without corticosteroids cover. We also aimed to determine other neonatal complications such as sepsis, hypoglycemia, and hyperbilirubinemia.

Methods

We conducted a retrospective descriptive study from January 2010 to December 2015 on all Omani women who delivered by elective cesarean section at Sultan Qaboos University Hospital between 37+0 and 38+6 weeks gestation.

Results

Among 650 patients included in the study, 20.8% (n = 135) received corticosteroids antenatally and 79.2% did not. RDS was found in 16 out of 650 neonates, making the prevalence of RDS 2.5%. Higher gravidity and parity and a mean gestational age of less than 37.6 weeks, were associated with a significant risk of RDS. Administration of antenatal corticosteroids did not change the respiratory morbidity in the newborns (p = 0.340). A mean birth weight of 2.9 kg was associated with a significant risk of RDS (p = 0.043). All 16 newborns required neonatal intensive care unit admission and ventilator support. The most common ventilatory support used was continuous positive airway pressure (56.2%). The most common secondary complication in neonates diagnosed with RDS was transient tachypnea of the newborn (53.8%).

Conclusions

The prevalence of RDS was low. Giving antenatal corticosteroids for patients with planned elective cesarean at term did not seem to have a beneficial effect on neonatal respiratory morbidity. Further studies with larger sample size including multiple centers is recommended.

Effects of home-based pelvic floor muscle training on decreasing symptoms of stress urinary incontinence and improving the quality of life of urban adult Omani women: A randomized controlled single-blind study

AIM

This study aims to determine the effectiveness of home-based pelvic floor muscle training (PFMT) on decreasing the severity of symptoms and improving the quality of life (QOL) among Omani women with stress urinary incontinence (SUI).

METHODS

A randomized controlled single-blind trial was conducted in three primary health care centers in Muscat. Eligible women who were diagnosed with SUI (from a concurrent phase-I study which was a cross-sectional study to determine the prevalence of urinary incontinence in Oman) were invited to take part. The consenting subjects were randomly allocated to either an intervention group (unsupervised PFMT) or a control group (lecture with no PFMT). Baseline and 12-week assessment of both groups was carried out for the primary outcome using the validated Arabic version of the International Consultation on Incontinence Questionnaire (ICIQ)-short form and the secondary outcome by blinded measures of pelvic floor muscle (PFM) strength using the modified Oxford grading system (MOGS), endurance, and perineometer.

RESULTS

A total of 73 subjects were included in the study. They were randomly divided into two groups. Both groups were similar at the baseline in terms of sociodemographic characteristics, ICIQ score, and PFM strength. At the 12-weeks assessment, there was a significant difference in the ICIQ score (P < .001) between the intervention group and the control one. There was no statistical difference between the two groups in MOGS, endurance, or perineometer values.

CONCLUSIONS

The home-based PFMT is an effective treatment in reducing the severity of symptoms and improving the QOL in women with SUI.

Postoperative Functional and Cosmetic Satisfaction among Subjects Undergoing Open Versus Endonasal Septorhinoplasty: Five Years' Experience from an Open-label Study at a Tertiary Care Center in Oman

Objectives

We sought to compare functional and cosmetic satisfaction among male and female patients undergoing open and closed septorhinoplasty within sub-groups of indications for the surgery at a tertiary care hospital in Oman.

Methods

We conducted a prospective study in the ear, nose, and throat surgery department at Sultan Qaboos University Hospital from 2010 to 2015. All patients aged above 17 years, without dysmorphic pathologies, and due to be operated through open or endonasal septorhinoplasty based on the appropriate indications (functional or cosmetic or functional and cosmetic), were included in the study.

Results

Out of 215 patients who underwent septorhinoplasty, 30 were lost to follow-up. One-hundred and eighty-five patients (124 males and 61 females) available for postoperative assessment had been allocated to septorhinoplasty by the endonasal approach (n = 89; 59 males and 30 females) or open approach (n = 96; 65 males and 31 females) based on their indications for surgery: functional (n = 98; 64 males and 34 females); cosmetic (n = 39; 23 males and 16 females); and both functional and cosmetic (n = 48; 37 males and 11 females). Sex-wise distribution across different age groups for the specific surgical technique based on indication for surgery did not show any significant differences within any of the respective sub-groups. Both sexes reported no significant difference in satisfaction per their scores on the functional satisfaction scale post open or endonasal intervention. However, in their cosmetic satisfaction scale scores, a significantly higher proportion of males within the functional indication for surgery subgroup (90.9%) expressed satisfaction with the open surgical approach than the 71.0% males operated by the endonasal approach (p = 0.041).

Conclusions

Males undergoing septorhinoplasty for functional indications expressed significant satisfaction with the open surgical approach compared with the endonasal approach on the cosmetic satisfaction scale. This study could accrue only 185 patients during the five-year study period and hence was unable to generate any significant evidence to prove any differences in postoperative functional and cosmetic satisfaction outcomes within sub-groups based on other indications for surgery for males and females separately.

Methylphenidate improves executive functions in patients with traumatic brain injuries: a feasibility trial via the idiographic approach

Background

Road traffic accidents are known to be the main cause of traumatic brain injury (TBI). TBI is also a leading cause of death and disability. This study, by means of the idiographic approach (single-case experimental designs using multiple-baseline designs), has examined whether methylphenidate (MPH - trade name Ritalin) had a differential effect on cognitive measures among patients with TBI with the sequel of acute and chronic post-concussion syndromes. The effect on gender was also explored.

Methods

In comparison with healthy controls, patients with TBI (acute and chronic) and accompanying mild cognitive impairment (MCI) were screened for their integrity of executive functioning. Twenty-four patients exhibiting executive dysfunction (ED) were then instituted with the pharmacological intervention methylphenidate (MPH). The methylphenidate was administered using an uncontrolled, open label design.

Results

The administration of methylphenidate impacted ED in the TBI group but had no effect on mood. Attenuation of ED was more apparent in the chronic phases of TBI. The effect on gender was not statistically significant with regard to the observed changes.

Conclusions

To our knowledge, this is the first feasibility trial from the Arabian Gulf to report the performance of a TBI population with mild cognitive impairment according to the IQCODE Arabic version. This investigation confirms anecdotal observations of methylphenidate having the potential to attenuate cognitive impairment; particularly those functions that are critically involved in the integrity of executive functioning. The present feasibility trial should be followed by nomothetic studies such as those that adhere to the protocol of the randomized controlled trial. This evidence-based research is the foundation for intervention and future resource allocation by policy- or public health decision-makers.

Vitamin B12 Deficiency in Diabetic Patients on Metformin Therapy: A cross-sectional study from Oman

Objectives

This study aimed to determine the prevalence of vitamin B12 deficiency amongst diabetic patients on metformin therapy.

Methods

This cross-sectional study was conducted at general clinics at the University Health Center and diabetes outpatient clinics at Sultan Qaboos University Hospital, Muscat, Oman, between January and December 2017. All Omani adults who were diagnosed with type 2 diabetes mellitus and took metformin were invited to participate in the study. The variables included in this study were age, gender, duration of diabetes, dose and duration of metformin therapy, haemoglobin and glycosylated haemoglobin level.

Results

A total of 248 subjects were included (response rate = 95.4%) of which 26 (10.5%) were vitamin B12 deficient and 53 (21.4%) were borderline deficient. The mean daily dose of metformin was highest among vitamin B12 deficient group (1,981 ± 222 mg; P = 0.004).

Conclusion

The prevalence of vitamin B12 deficiency is considerable among diabetic patients on metformin therapy. Further research is needed to confirm the need for routine screening and monitoring.

Urinary Incontinence Among Omani Women: Prevalence, risk factors and impact on quality of life

Objectives

Urinary incontinence (UI) in women is a common health problem which can have a negative impact on quality of life (QOL). This study aimed to determine the prevalence, risk factors and impact of UI on the QOL of Omani women attending primary healthcare centres in Muscat, Oman.

Methods

This cross-sectional study was conducted at three primary healthcare centres in Muscat from April to August 2018. Women who were 20–50 years of age, not pregnant, not in the six-month postnatal period, not seriously ill and not diagnosed with pelvic organ prolapse were included. A self-administered questionnaire using the International Consultation Incontinence Questionnaire-Short Form was used to evaluate the frequency, severity and impact of UI on QOL.

Results

A total of 1,070 women were included in this study (response rate = 92.5%). The mean age was 31.39 ± 7.64 years. UI was reported by 369 (34.5%) women, of whom 182 (49.3%) had stress UI, 97 (26.3%) had urgency UI, 88 (23.8%) had mixed UI and two (0.5%) had other UI. Age, body mass index (BMI), having been married or employed, hypertension, cough, constipation and vaginal or assisted vaginal delivery during the previous birth were significant risk factors for UI. Only 41 (11.1%) out of the 369 women with UI had ever sought medical advice despite the fact that more than two thirds of the women with UI reported negative effects on their QOL.

Conclusion

UI is a common medical problem in Oman. Several risk factors, including age and BMI, were identified. Despite its negative consequences for QOL, women were found to be reluctant to seek medical attention for the condition.

Ossification of Posterior Longitudinal Ligament of Cervical Spine Among Omani Patients Referred for CT Scan at a Tertiary Care Hospital in Oman

Objectives

We sought to evaluate the proportion of ossification of the posterior longitudinal ligament (OPLL) of the cervical spine and associated factors among Omani patients.

Methods

We reviewed the cervical spine computed tomography (CT) scans of all patients referred to the Radiology Department, Sultan Qaboos University Hospital, from 2011 to 2017. Descriptive statistics were employed to determine the proportion of OPLL. We used the chi-square test to determine the association of age, gender, and diabetes mellitus with OPLL.

Results

A total of 843 patients aged ≥ 20 years were included in the study. The proportion of OPLL was 2.7% and was more frequent in men (3.2%) than women (1.9%). The male to female ratio of OPLL was 1.7:1.0. OPLL occurrence was significantly more in non-diabetic patients (p < 0.001). No significant association was found between OPLL with gender (p = 0.281) and age (p = 0.878).

Conclusions

The observed proportion of OPLL in this single-center study is relatively low, but the finding is important as the condition can eventually lead to debilitating neurologic outcomes affecting the patient's quality of life. OPLL occurrence was significantly more in non-diabetic patients, which necessitate further research on OPLL in a larger sample across Oman.

Patients’ Perceptions of Communication and Clinical Skills of Primary Healthcare Physicians in Oman

Objectives

As a large proportion of patients are seen in primary healthcare (PHC) centres, it is important to explore patients’ perceptions of communication and clinical skills of PHC physicians. In Oman, PHC is provided by both trained family physicians (FPs) and general practitioners (GPs).

Methods

This cross-sectional study was conducted at 12 PHC centres in Muscat Governorate, Oman between November 2014 and August 2015. Adult Omani patients’ perceptions of Omani and other Arabic-speaking doctors were examined using an Arabic translation of a validated self-administered questionnaire.

Results

A total of 626 patients completed the questionnaire (response rate: 100%). The patients’ responses were significantly more positive towards FPs compared to GPs on whether the doctor provided reassurance (P = 0.03), took a complete medical history (P = 0.03) and gave the patient the opportunity of a follow-up with the same doctor (P = 0.01).

Conclusion

Certain skills in communication and clinical aspects of FPs were favourably viewed by patients compared to GPs.

Effects of an Adenotonsillectomy on the Cognitive and Behavioural Function of Children Who Snore: A naturalistic observational study

Objectives

This study aimed to evaluate cognitive and behavioural changes among 9-14-year-old Omani children with obstructive sleep apnoea (OSA) after an adenotonsillectomy (AT).

Methods

This naturalistic observational study was conducted at the Sultan Qaboos University Hospital, Muscat, Oman, between January 2012 and December 2014. Omani children with adenotonsillar hypertrophy (ATH) underwent overnight polysomnography and those with confirmed OSA were scheduled for an AT. Cognitive and behavioural evaluations were performed using standardised instruments at baseline prior to the procedure and three months afterwards.

Results

A total of 37 children were included in the study, of which 24 (65%) were male and 13 (35%) were female. The mean age of the males was 11.4 ± 1.9 years, while that of the females was 11.1 ± 1.5 years. Following the AT, there was a significant reduction of 56% in mean apnoea-hypopnoea index (AHI) score (2.36 ± 4.88 versus 5.37 ± 7.17; P <0.01). There was also a significant positive reduction in OSA indices, including oxygen desaturation index (78%), number of desaturations (68%) and number of obstructive apnoea incidents (74%; P <0.01 each). Significant improvements were noted in neurocognitive function, including attention/concentration (42%), verbal fluency (92%), learning/recall (38%), executive function (52%) and general intellectual ability (33%; P <0.01 each). There was a significant decrease of 21% in both mean inattention and hyperactivity scores (P <0.01 each).

Conclusion

These results demonstrate the effectiveness of an AT in improving cognitive function and attention deficit hyperactivity disorder-like symptoms among children with ATH-caused OSA. Such changes can be observed as early as three months after the procedure.

Prevalence of diffuse idiopathic skeletal hyperostosis among elderly subjects referred for radiological investigation in tertiary hospital at Oman

Diffuse idiopathic skeletal hyperostosis (DISH) is characterized by calcification of different entheseal sites including the anterior longitudinal ligament of the spine. There is no documented information about DISH in Oman. This study determined the prevalence of DISH and associated factors among elderly subjects in a national tertiary care referral hospital in Oman. This retrospective study reviewed chest X-rays of all patients aged more than 50 years, referred to the radiology department of Sultan Qaboos University Hospital in the year 2016, based on the Resnick's criteria. The prevalence was expressed as proportions across age groups and sex. Chi-square test and logistic regression analysis was done to determine the association of the age and sex with DISH. A total of 1305 chest X-rays of patients were reviewed. The overall prevalence of DISH was 10%, with male to female ratio of 1.56:1. The odds ratio for males and increasing age were 1.63 (95% confidence interval [CI], 1.12–2.3; P<0.05) and 1.34 (95% CI, 1.14–1.58; P<0.001) respectively. The prevalence increased with age to maximum of 13% in the age group of ≤80. The pre-stage DISH prevalence was 9.3% and more frequently observed among males. Prevalence of DISH in the national tertiary care referral center in Oman is lower than in Jewish population, almost similar to Japanese, but higher than in Koreans. DISH prevalence is positively associated with age and sex. It is necessary to take appropriate precautionary measures to target the ageing population in Oman, especially elderly males.

Daytime Sleepiness Among Young Adult Omani Car Drivers

Objectives

Sleepiness and fatigue play significant roles in exacerbating the occurrence of car crashes. However, there is a dearth of studies examining the prevalence of sleepiness while driving among Omanis. This study aimed to determine the proportion of young Omani adults who confess to daytime sleepiness while driving and to investigate associations between gender, daytime sleepiness and risk of obstructive sleep apnoea syndrome (OSAS).

Methods

This cross-sectional study took place at the Sultan Qaboos University Hospital, Muscat, Oman, between May and July 2014 and included 600 young adult Omani non-commercial drivers. The Berlin Questionnaire and Epworth Sleepiness Scale (ESS) were distributed among the participants, along with additional questions about their sleeping habits. Associations between daytime sleepiness while driving and nocturnal sleep duration, risk of OSAS and gender were determined.

Results

A total of 492 private vehicle drivers took part in the study (response rate: 82%), of which 50.4% were male. Overall, 124 Omanis (25.2%) reported experiencing daytime sleepiness while driving at least once per month. There was a significant association between nocturnal sleep duration of <6 hours and sleepiness while driving (P = 0.042). Female participants were significantly more likely to score >10 on the ESS, indicating a greater propensity for daytime sleepiness (P = 0.006). However, male drivers were significantly more likely to report sleepiness while driving (P = 0.001).

Conclusion

Sleepiness while driving was common among young male drivers in Oman and might be due to nocturnal sleep deprivation. Further studies are needed so that preventative measures can be developed.

Antenatal prevalence of fear associated with childbirth and depressed mood in primigravid women

AIM

To investigate the antenatal prevalence of fear of childbirth and its association with depressed mood in low-risk primigravidae in a referral teaching hospital.

SETTINGS AND DESIGN

The study was conducted in a tertiary referral center catering to three districts in the state of Kerala. This was a cross-sectional study with internal comparison of associated factors.

MATERIALS AND METHODS

Malayalam translation (translation back translation) of Edinburgh Postnatal Depression Scale (EPDS) was self-administered by the participants. It was followed by a structured interview based on the International Classification of Diseases 10 (ICD 10) after which the EPDS scale was scored.

STATISTICAL ANALYSIS

Chi-square test was used to compare the presence of fear in women with a EPDS of ≥ 12 and the association of fear and depression.

RESULTS

Fear associated with childbirth was expressed by 17.7% women. The prevalence of depressed mood based on the EPDS (score > 12) was 9.8% but based on the ICD 10 criteria, the prevalence of depression was 8.7%. A significant number of women with depressed mood and clinical depression had fear of childbirth of some sort.

CONCLUSIONS

A significant number of primigravid women with depressed mood and clinical depression had fear of childbirth of some sort.

Oman world health survey: part 1 - methodology, sociodemographic profile and epidemiology of non-communicable diseases in oman

The Oman World Health Survey (OWHS) is community-based household survey conducted in first half of 2008 for Omani and non-Omani population aged 18 years and above. It is a part of the World Health Survey (WHS) series which was developed by the World Health Organization (WHO) as a means to compile comprehensive information on the health of populations in different countries. A multi-stage stratified cluster sampling was designed to select about 5000 eligible subjects 18 years and above. The main objectives of the survey were to determine the national prevalence of Hypertension, Diabetes Mellitus, Obesity, Lipoproteins, Anemia, Visual ability and Cognitive functions. Among Omanis, the prevalence of Hypertension (40.3%), Diabetes Mellitus (12.3%), Obesity using BMI (24.1%), Total cholesterol (33.6%), Anemia in males 20% and in non-pregnant females was 32.2%. In Oman, the increase in lifestyle-related non communicable diseases has emerged as new health challenges to the country which need to be addressed.

The adequacy of informed consent forms in genetic research in Oman: a pilot study

Genetic research presents ethical challenges to the achievement of valid informed consent, especially in developing countries with areas of low literacy. During the last several years, a number of genetic research proposals involving Omani nationals were submitted to the Department of Research and Studies, Ministry of Health, Oman. The objective of this paper is to report on the results of an internal quality assurance initiative to determine the extent of the information being provided in genetic research informed consent forms. In order to achieve this, we developed checklists to assess the inclusion of basic elements of informed consent as well as elements related to the collection and future storage of biological samples. Three of the authors independently evaluated and reached consensus on seven informed consent forms that were available for review. Of the seven consent forms, four had less than half of the basic elements of informed consent. None contained any information regarding whether genetic information relevant to health would be disclosed, whether participants may share in commercial products, the extent of confidentiality protections, and the inclusion of additional consent forms for future storage and use of tissue samples. Information regarding genetic risks and withdrawal of samples were rarely mentioned (1/7), whereas limits on future use of samples were mentioned in 3 of 7 consent forms. Ultimately, consent forms are not likely to address key issues regarding genetic research that have been recommended by research ethics guidelines. We recommend enhanced educational efforts to increase awareness, on the part of researchers, of information that should be included in consent forms.

Nutrition knowledge, beliefs and dietary habits among elderly people in Nizwa, Oman: implications for policy

The nutritional needs of the ageing population require special attention. We undertook a cross-sectional, community-based, household survey in Nizwa wilayat, Oman to study nutrition-related knowledge and beliefs and self-reported dietary habits among a sample of elderly people. The response rate for the household interview was 99.3% from a total sample of 2041. About 45% of the elderly were overweight or obese. Overall we found poor knowledge of nutrition plus some nutritional imbalances and low levels of physical activity. Significant sex differences existed in elderly peoples' nutritional knowledge, consumption of fluids, milk and sweets, use of dietary regimens and experience of appetite change. The findings warrant reorientation of the existing health promotion strategy for the elderly.

Prevalence and age-of-onset distributions of DSM IV mental disorders and their severity among school going Omani adolescents and youths: WMH-CIDI findings

BACKGROUND

There is a dearth of studies exploring the magnitude of mental disorders amongst adolescents and youths in the Arab world. To our knowledge, this phase 2 survey in Oman is the first nationally representative school-based study to determine the prevalence of DSM-IV mental disorders (lifetime and over the preceding 12 months), their age-of-onset distributions and determine their severity over the past 12 months using the World Mental Health-Composite International Diagnostic Interview, the WMH-CIDI, used for international comparison.

METHODS

A total of 1,682 (91.61%) students out of 1836 students who formed the phase 2 random sub-sample of a multi-stage, stratified, random sampling design (phase 1), participated in the face-to-face structured interview using the Arabic-version of WMH-CIDI 3.0.

RESULTS

The phase 1 results using the General Health Questionnaire (GHQ-12) and Child Depression Inventory (CDI) showed depressive symptoms to be 17% prevalent in the larger sample of 5409 adolescents and youths. Amongst the phase 2 respondents from this sample, 13.9% had at least one DSM IV diagnostic label. The lifetime prevalence of Major Depressive Disorder (MDD) was 3.0%; Bipolar Mood Disorder (BMD) was 1%, Specific phobia 5.8% and Social phobia 1.6%. The female gender was a strong predictor of a lifetime risk of MDD (OR 3.3, 95% CI 1.7-6.3, p = 0.000); Any Mood Disorders (OR 2.5, 95% CI 1.4-4.3, p = 0.002) and Specific Phobia (OR 1.5, 95% CI 1.0-2.4, p = 0.047). The severity of illness for cases diagnosed with 12 month DSM IV disorders was found to be 80% lower in females (OR 0.2, 95%CI 0.0-0.8). The estimates over the previous 12 month period when compared with the lifetime prevalence showed a 25% to 40% lower prevalence for MDD, Specific phobia, Social phobia, Any Anxiety Disorders (AAD) and Any Mood disorders (AMD) while the rate was 80% lower for Separation Anxiety Disorder/Adult Separation Anxiety (SAD/ASA). Mood disorders were significantly lower in the 14-16 age groups (70% lower) in comparison to the older age groups and AMD showed a linear increase in prevalence across increasing age groups (p = 0.035).

CONCLUSION

The implications of the present findings are not clear cut, however this study endorses the adult CIDI studies findings that mental disorders do begin earlier in life. The relatively lower prevalence of DSM IV depressive disorders cautions against any conclusive interpretation of the inflated results based on the exclusive study of the depressive symptoms alone in the same sample in the same time period. The female gender proved to be a strong predictor of lifetime risk of MDD, any mood disorder and specific phobia. Under-reporting by males or some other gender-specific factors may have contributed to such a discrepancy. The odds of the severity of illness for cases with 12 month DSM IV disorders were significantly lower in females.
