The Use of Dietary Supplements for Mental Health Among the Saudi Population

Introduction

Despite the limited evidence about the efficacy and safety of dietary supplement use for mental health, people tend to use them quite often. Generally the use of supplements among Saudi population shown to be prevalent, although limited studies that assessed their use for the improvement of mental health.

Objectives

Identify the prevalence of dietary supplements use for mental health among the population in Saudi Arabia and also determine the factors that affect the use of dietary health supplements for mental health.

Methods

A cross-sectional study of a convenience sample of 443 participants from various regions in Saudi Arabia. Questionnaire includes demographics, dietary use supplement assessment, and mental health assessment via the patient health questionnaire (PHQ-9), generalized anxiety disorder questionnaire (GAD-7), and insomnia severity index (ISI).

Results

The prevalence of DS among the Saudi population reached 44%. Vitamin D and Melatonin were the most commonly reported DS used for mental health among the study population. The use of DS was associated with three times higher odds in patients who had previous mental health disorder diagnoses (OR 2.972; 95%CI; 1.602-5.515). The chance of using DS almost doubled in patients with subthreshold and moderate-severe insomnia (OR 1.930;95% CI 1.191-3.126) and (OR 2.485; 95% CI 1.247- 4.954) respectively.

Conclusions

Despite the limited evidence about the efficacy and safety of dietary supplement use for mental health, people tend to use them quite often. Although the use of supplements among Saudi population shown to be prevalent, limited studies assessed their use for the improvement of mental health.

Quarantine-related depression and anxiety during coronavirus disease (COVID-19) outbreak

Introduction

Psychological well-being has an important impact on individuals. In the face of the health threat of COVID-19, psychological changes as fear stress anxiety and depression is reported.

Objectives

Explore the prevalence of depression and anxiety among people under quarantine during the COVID-19 outbreak in Saudi Arabia.

Methods

A cross-sectional study of a convenience sample of 65 participants who were quarantined at multiple hotels under the supervision of the Saudi Ministry of Health. The patient health questionnaire (PHQ-9) and generalized anxiety disorder questionnaire (GAD-7) were used to assess depression and anxiety.

Results

The majority of the participants were male (66.2%), aged 18–29 (47.7%) from the Eastern region (66.15%), who were still waiting for the result of the COVID-19 test (64.6%). Approximately half of the sample had depressive and anxiety symptoms (49.2% and 44.6%, respectively). The depression mean score was significantly higher only among the 18–29 age group. However, the depression and anxiety mean scores were higher among females than males and among participants with positive COVID-19 test results compared to those who had pending or negative results. The anxiety mean score was higher during the first week of quarantine, but the depression mean score was higher during later weeks.

Conclusions

Depression and anxiety were prevalent among people in quarantine during the beginning of the COVID-19 outbreak in Saudi Arabia. It is crucial to study the most effective interventions to reduce the psychological consequences, especially for vulnerable groups. Longitudinal research studies need to be conducted to follow up regarding participants’ mental health symptoms and evidence-based interventions.

Cross-Priming Dendritic Cells Exacerbate Immunopathology After Ischemic Tissue Damage in the Heart

BACKGROUND

Ischemic heart disease is a leading cause of heart failure and despite advanced therapeutic options, morbidity and mortality rates remain high. Although acute inflammation in response to myocardial cell death has been extensively studied, subsequent adaptive immune activity and anti-heart autoimmunity may also contribute to the development of heart failure. After ischemic injury to the myocardium, dendritic cells (DC) respond to cardiomyocyte necrosis, present cardiac antigen to T cells, and potentially initiate a persistent autoimmune response against the heart. Cross-priming DC have the ability to activate both CD4+ helper and CD8+ cytotoxic T cells in response to necrotic cells and may thus be crucial players in exacerbating autoimmunity targeting the heart. This study investigates a role for cross-priming DC in post-myocardial infarction immunopathology through presentation of self-antigen from necrotic cardiac cells to cytotoxic CD8+ T cells.

METHODS

We induced type 2 myocardial infarction-like ischemic injury in the heart by treatment with a single high dose of the β-adrenergic agonist isoproterenol. We characterized the DC population in the heart and mediastinal lymph nodes and analyzed long-term cardiac immunopathology and functional decline in wild type and Clec9a-depleted mice lacking DC cross-priming function.

RESULTS

A diverse DC population, including cross-priming DC, is present in the heart and activated after ischemic injury. Clec9a-/- mice deficient in DC cross-priming are protected from persistent immune-mediated myocardial damage and decline of cardiac function, likely because of dampened activation of cytotoxic CD8+ T cells.

CONCLUSION

Activation of cytotoxic CD8+ T cells by cross-priming DC contributes to exacerbation of postischemic inflammatory damage of the myocardium and corresponding decline in cardiac function. Importantly, this provides novel therapeutic targets to prevent postischemic immunopathology and heart failure.
