Background: The Gulf Cooperation Council (GCC), with a predominant ‘youth bulge’ among its 54 million people, has witnessed an exponential increase in research pertinent to child and adolescent mental health (CAMH). Aside from a few narrative reviews, to date, no critical appraisal examining the magnitude of CAMH has emerged from this region. Aims: This study aimed to report the prevalence rates of CAMH disorders in the GCC through a systematic review of the existing literature followed by a meta-analysis. Methods: A systematic review of the literature from the six GCC countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates) was conducted. The databases used included Scopus, ProQuest, Pubmed, and a final check was performed on Google Scholar to account for any remaining studies that may have still been under review. Meta analytic techniques were then used to estimate prevalence rates of each specific mental disorder, i.e. ADHD, depression, anxiety, stress, eating disorders, and tobacco use disorder. Results: A total of 33 studies from the six countries were included. The pooled prevalence of ADHD as per the Vanderbilt ADHD Diagnostic Rating Scale (VADHDDRS), clinical judgments, Attention Deficit Disorders Evaluation Scale (ADDES), and the Strengths and Difficulties Questionnaire (SDQ) was found to be 13.125%, 13.38%, 26.135%, and 12.83%, respectively. The pooled prevalence of depressive symptoms solicited by the Patient Health Questionnaire (PHQ-9), Depression, Anxiety, and Stress Scale (DASS), and Mini-International Neuropsychiatric Interview for Children and Adolescents (MINI Kid) was 44.684%, 45.09%, and 26.12%, respectively. The pooled prevalence of anxiety according to the DASS and the MINI Kid was 57.04% and 17.27%, respectively, while the pooled prevalence of stress as per the DASS was found to be 43.15%. The pooled prevalence of disordered eating solicited by the Eating Attitudes Test (EAT-26) was 31.55%. Lastly, the pooled prevalence of tobacco use disorder per the Global Youth Tobacco Survey was 19.39%. Discussion: To date, this is the first systematic review and meta-analysis of its kind from the GCC. The prevalence rate of CAMH disorders appears to be in the upper range of international trends. The higher rates could be attributed to the existing studies using suboptimal methodological approaches and instruments to solicit the presence of CAMH.

Recent research has shown that the prevalence of stroke incidents and the number of survivors in developing countries surpass those from developed countries. This study aimed to enumerate the prevalence of post-stroke psychiatric and cognitive symptoms among stroke survivors from West and South Asia and Africa through a systematic review and meta-analysis. Data from each country was systematically acquired from five major databases (PsycINFO, Web of Science, Scopus, PubMed/Medline, and Google Scholar (for any missing articles and grey literature)). Meta-analytic techniques were then used to estimate the prevalence of various post-stoke psychiatric and cognitive symptoms. A total of 36 articles were accrued from 11 countries, of which 25 were evaluated as part of the meta-analysis. The pooled prevalence of post-stroke depression as per the Hospital Anxiety and Depression Scale (HADS), Hamilton Depression Rating Scale, Patient Health Questionnaire, Schedules for Clinical Assessment in Neuropsychiatry (SCAN), Geriatric Depression Scale, and the Montgomery–Asberg Depression Rating Scale ranged from 28.00 to 50.24%. Pooled prevalence of post-stroke anxiety based on the HADS and SCAN was 44.19% and 10.96%, respectively. The pooled prevalence of post-stroke cognitive impairment as per the Mini-Mental Status Examination was 16.76%. This present review has suggested that both psychiatric and cognitive symptoms are common among stroke survivors. Concerted efforts are needed to institute robust studies using culturally sensitive measures to contemplate mechanisms that address the unmet needs of this vulnerable population.

Depressive illnesses in non-Western societies are often masked by somatic attributes that are sometimes impervious to pharmacological agents. This study explores the effectiveness of repetitive transcranial magnetic stimulation (rTMS) for people experiencing treatment-resistant depression (TRD) accompanied by physical symptoms. Data were obtained from a prospective study conducted among patients with TRD and some somatic manifestations who underwent 20 sessions of rTMS intervention from January to June 2020. The Hamilton Rating Scale for Depression (HAMD) was used for clinical evaluation. Data were analysed using descriptive and inferential techniques (multiple logistic regression) in SPSS. Among the 49 participants (mean age: 42.5 ± 13.3), there was a significant reduction in posttreatment HAMD scores compared to baseline (t = 10.819, p < 0.0001, and 95% CI = 8.574–12.488), indicating a clinical response. Approximately 37% of the patients responded to treatment, with higher response rates among men and those who remained in urban areas, had a history of alcohol use, and were subjected to the standard 10 HZ protocol. After adjusting for all extraneous variables, the rTMS protocol emerged as the only significant predictor of response to the rTMS intervention. To our knowledge, this is the first study to examine the effectiveness of rTMS in the treatment of somatic depression.

Background: Most documented cases of menstrual psychosis have been from Euro-American populations with reports from cross-cultural populations being only a few. A primary aim was to determine whether the cyclical/episodic nature of menstrual psychosis among case series observed at a tertiary care unit in Oman fulfills the diagnostic criteria of the International Classification of Diseases (ICD-10) and diverge into Brockington’s sub-types (World Psychiatry. 2005;4(1):9–17). Related aims were to solicit measures of psychometric functioning of those with menstrual psychosis and associated idioms of distress. Methods: A series of consecutive patients seeking psychiatric consultation from January 2016 to December 2017 were screened via structured interview—Composite-International Diagnostic Interview (CIDI) and Brockington’s sub-types. The identified patients (n = 4) also underwent psychometric evaluation including examination of affective functioning, intellectual capacity and neuropsychological functioning (i.e.attention and concentration, learning and remembering, executive function, processing speed and speech and language). The analysis of outcome measures was via an idiographic approach. Results: The spectrum of distress among people with menstrual psychosis does not fit existing psychiatric nosology. Evaluations revealed that a majority of the participants displayed something akin to morbid phenomena relating to manic and psychotic symptoms. In the parlance of traditional Omani society, this would be termed “spirit possession”. In terms of classification by timing within the menstrual cycle as expounded by Brockington, the present case series in Oman fulfilled the definition of catamenial psychosis and paramenstrual psychosis. With regard to psychometric function, all participants performed adequately on indices of intellectual functioning but appeared to have impairments in neuropsychological functioning, including the dimensions of processing speed, episodic memory, and executive functioning. Within the given society, the periodicity of mind alteration has been attributed to spirit possession. Conclusions: This is one of the first case series of its kind in the country elucidating whether the manifestation of menstrual psychosis among individuals in Oman fulfills the subtypes postulated by Brockington. The present case series suggests that menstrual psychosis is marked with neuropsychological impairments that were previously observed in other phasic manic episodes or brief psychotic disorders.

BACKGROUND: Over the past few years, there has been an increasing interest in viewing the diagnosis of familial hypercholesterolemia (FH) through the lens of the biopsychosocial model. However, other than a few epidemiological surveys, there is a dearth of studies from emerging economies that have examined FH using the biological, psychological, and socio-environmental facets of the aforementioned model. AIM. The three aims of the current study were as follows: (i) to examine the psychosocial status among patients with genetically confirmed FH, (ii) to compare their intellectual capacity and cognitive outcomes with a reference group, and (iii) to examine the relationship between health literacy and cognitive functioning. METHOD: Consecutive FH patients referred to the lipid clinic at a tertiary care center for an expert opinion were recruited into this study conducted from September 2019 to March 2020. Information regarding psychosocial functioning, health literacy, quality of life, and affective ranges was surveyed. Indices of current reasoning ability and cognition (attention and concentration, memory, and executive functioning) were compared with a socio-demographically-matched reference group. The current hypothesis also explored the impact of FH on health literacy and cognition. RESULT: A total of 70 participants out of 106 (response rate: 66.0%) initially agreed to participate. However, 18 out of 70 dropped out of the study, yielding a final total of 52 FH patients. With 27 (51.9%) males and 25 (48.1%) females, the mean participant age stood at 37.2 years (SD = 9.2), ranging from 21 to 52 years of age. In the psychosocial data, thirty-two percent (n = 17) of them had anxiety (HADS ≥ 8), and twenty-five percent (n = 13) had depressive symptoms (HADS ≥ 8). The performance of the FH patients was significantly impaired compared to the control group on the indices of current reasoning ability and all domains of cognitive functioning. In the univariate analysis conducted to compare cognitive functioning with health literacy status, only indices of attention and concentration emerged as being significant. CONCLUSION: The current study indicates that the FH population is marked with impediments in biopsychosocial functioning, including indices tapping into the integrity of health literacy, quality of life, affective ranges, and higher functioning such as cognition and current reasoning ability when compared with a socio-demographically-matched reference group. The present results support the hypothesis that chronic diseases vis-à-vis the sequelae of coronary artery disease can potentially impede biopsychosocial functioning.

OBJECTIVE: This study aims to assess and compare demographic and psychological factors and sleep status of frontline HCWs in relation to non-frontline HCWs DESIGN, SETTINGS, AND PARTICIPANTS This cross-sectional study was conducted using an online survey from the 8th to the 17th of April 2020 across varied health care settings in Oman accruing 1139 HCWS. MAIN OUTCOMES AND MEASURES Mental health status was assessed using Depression, Anxiety, and Stress Scales (DASS-21), and insomnia was evaluated by the Insomnia Severity Index (ISI). Samples were categorized into the frontline and non-frontline groups. Chi-square, odds ratio, and independent t-tests were used to compare groups by demographic and mental health outcomes. Results This study included 1139 HCWs working in Oman. There was a total of 368 (32.3%), 388 (34.1%), 271 (23.8%), and 211 (18.5%) respondents reported to have depression, anxiety, stress, and insomnia, respectively while working during the pandemic period. HCWs in the frontline group were 1.4 times more likely to have anxiety (OR=1.401, p=0.007) and stress (OR=1.404, p=0.015) as compared to those working in the non-frontline group. On indices of sleep-wake cycles, HCWs in the frontline group were 1.37 times more likely to report insomnia (OR=1.377, p=0.037) when compared to those working in the non-frontline group. No significant differences in depression status between workers in the frontline and non-frontline groups were found (p=0.181). CONCLUSIONS AND RELEVANCE To our knowledge, this is the first study to explore the differential impacts of the COVID-19 pandemic on different grades of HCWs. This study suggests that frontline HCWs are disproportionally affected compared to non-frontline HCWs. The problem with managing sleep-wake cycles and anxiety symptoms were highly endorsed among frontline HCWs. As psychosocial interventions are likely to be constrained owing to the pandemic, mental health care must first be directed to frontline HCWs.
