Risk of suicidal behavior in patients with major depression and bipolar disorder - A systematic review and meta-analysis of registry-based studies.

Suicide is a health priority and one of the most common causes of death in mood disorders. One of the limitations of this type of research is that studies often establish rates of suicide behaviors in mood disorders by using diverse comparison groups or simply monitoring cohort of patients over a time period. In this registry-based systematic review, national registers were identified through searches in six academic databases, and information about the occurrence of suicide behaviors in mood disorders was systematically extracted. Odds ratios were subsequently calculated comparing rates of death by suicide in mood disorders in comparison with age and period matched rates of death by suicide in the general population obtained from country-wide national registers. The aim was to provide the most recent summary of epidemiological and clinical factors associated to suicide in mood disorders whilst calculating the likelihood of death by suicide in mood disorders in comparison with non-affected individuals according to national databases. The study follows the Preferred Reporting Guidelines for Systematic Reviews and Meta-analyses and was prespecify registered on Prospero (CRD42020186857). Results suggest that patients with mood disorders are at substantially increased risk of attempting and dying by suicide. Several epidemiological, clinical and social factors are reported to be associated with clinical populations at risk of suicide. Meta-analyses of completed deaths by suicide suggest that the likelihood for dying by suicide in mood disorders is 8.62 times higher in major depression and 8.66 times higher in bipolar disorder with higher number of untoward events in women compared to men in both conditions. The likelihood of dying by suicide in major depressive disorders is higher in the first year following discharge. Clinical guidelines might consider longer periods of monitoring following discharge from hospital. Overall, due to the higher risk of suicide in mood disorders, efforts should be made to increase detection and prevention whilst focusing on reducing risk in the most severe forms of illness with appropriate treatment to promote response and remission at the earliest convenience.

Kikuchi-Fujimoto Disease in a 25-Year-Old Female: A Case Report.

BACKGROUND: Kikuchi-Fujimoto disease or histiocytic necrotizing lymphadenitis is a rare benign disease that presents as cervical lymphadenopathy and fever. CASE PRESENTATION: A 25-year-old South Asian female dentist, recently married, presented to our emergency department due to two weeks of fever, sore throat, swollen neck, and cough. The patient initially presented to a private clinic and was prescribed antibiotics on two visits. On physical examination, her neck was swollen with palpable and tender right posterior and submandibular lymph nodes. Oropharyngeal examination revealed pharyngeal hyperemia without tonsillar enlargement, exudates, or mucocutaneous ulcers. Ultrasound imaging revealed enlarged neck and thoracic and abdominal lymph nodes. CBC showed leukopenia and anemia of chronic disease. B2 microglobulin, lactate dehydrogenase, and kappa light chains were elevated. Anti-ANA, anti-dsDNA, HIV polymerase chain reaction (PCR), Quantiferon-tuberculosis (TB), and rapid plasma reagin were all negative. A lymph node biopsy confirmed the diagnosis of Kikuchi-Fujimoto disease. CONCLUSION: We believe this is the second case to be reported in the United Arab Emirates (UAE). Kikuchi-Fujimoto disease has a non-specific presentation that overlaps with several conditions including autoimmune, infectious, and malignant. Therefore, a thorough clinical approach and a high grade of clinical suspicion is required to rule out other possible differential diagnosis. Finally, Although Kikuchi-Fujimoto disease is mostly benign, clinicians should be careful as some patients might develop systemic lupus erythematosus (SLE), Still disease, or B cell lymphoma in the future.

Severe Hyponatremia in a 46-Year-Old Female With Pituitary Stalk Duplication and Primary Empty Sella Syndrome.

Pituitary duplication is a rare congenital malformation. It has been mainly reported in the pediatric and neonatal population, with few reported cases in the adult population. In this case report, we discuss the presentation of an adult female patient with pituitary stalk duplication and primary empty sella (PES). A 46-year-old South Asian female presented with severe euvolemic hyponatremia. Initial investigation showed low serum osmolality, high urine osmolality, high urinary sodium concentration, and normal chest X-ray. On physical examination, the patient had underdeveloped secondary sexual characteristics. Laboratory tests showed low follicle-stimulating hormone, luteinizing hormone, and estradiol. Prolactin was moderately elevated, morning cortisol was low, adrenocorticotropic hormone (ACTH) was within the lower normal range, ACTH dynamic test was suboptimal, and insulin-like growth factor 1 was low. MRI showed empty sella with duplication of the pituitary stalk and third ventricle sagging. Pituitary stalk duplication is a rare congenital malformation that can be associated with other craniofacial abnormalities. Here, we describe the occurrence of pituitary stalk duplication with PES. It is not known if the two conditions are associated with each other. However, we speculate that the duplication of the stalk might have altered the normal anatomy of the aperture in the sellar diaphragm creating a space for the third ventricle to sag or herniate, as well as compressing the pituitary gland.

Mental health, wellbeing and burnout among medical students in the United Arab Emirates.

BACKGROUND: Medical students tend to experience high levels of stress during their studies, that can result in mental health disorders and burnout, further affecting academic performance and later ability to practice. AIMS: To investigate previous and current mental health issues, significant sources of stress, burnout, and substance use among medical students in the United Arab Emirates (UAE). METHOD: We conducted an online survey to collect data on demographics, sources of stress, mental health problems, burnout, and substance use in 385 medical students from the UAE University. We used the Oldenburg Burnout Inventory (OLBI), the General Health Questionnaire 12 (GHQ-12), and the CAGE questionnaire. RESULTS: Our results indicated that 5.7% of participants had been diagnosed with a mental health condition prior to joining medical school, and that 21.6% of participants were diagnosed with a mental illness while in medical school. On the OLBI, 77.4% screened positive for burnout (81.3% for disengagement and 95.1% for exhaustion), with 74.5% screening positive for mental health difficulties on the GHQ-12 and <1% screening positive on the CAGE for problem drinking. There was a statistically significant positive correlation between scores on the OLBI and the GHQ-12. CONCLUSIONS: Our study indicated that high levels of stress, burnout and mental illness are experienced among medical students in the UAE.

Prevalence of Latent Tuberculosis Infection Among Rheumatology Patients and Management Practices in the United Arab Emirates: A Single-Center Retrospective Cohort Study.

Introduction Prior to immunosuppression, rheumatology patients are routinely screened for latent tuberculosis (TB) infection using interferon-gamma release assays (IGRAs). Variability in the management of latent and indeterminate IGRA results across institutions limited long-term outcome data. A retrospective study was conducted at Tawam Hospital, United Arab Emirates, to investigate the incidence and management protocols associated with positive and indeterminate IGRA results, as well as TB infection, among patients with rheumatic conditions. Methods A single-center retrospective observational study was performed at Tawam Hospital, Abu Dhabi, UAE. Ethical approval for this study was obtained from the Tawam Human Research Ethics Committee. Laboratory records and the hospital's electronic medical system were used to obtain information about IGRA results over a 12-year period (April 2010-April 2022). The hospital's electronic medical system was used to obtain patient information and subsequent management approaches of positive and indeterminate IGRAs. Moreover, long-term follow-up data were collected to determine the risk of TB reactivation in the cohort. Results We found a total of 1,012 positive and 223 indeterminate IGRA test results within the 12-year period. Within the rheumatology department, 123 positive and 39 indeterminate IGRA results were identified. In the indeterminate IGRA group, the majority were women (n = 24, 61.5%) and UAE nationals (n = 22, 56.4%), and their mean age was 38.6 years. Systemic lupus erythematosus was the most prevalent rheumatologic condition (n = 21, 53.8%). Thirteen (33.3%) were on disease-modifying anti-rheumatic drugs (DMARDs) and 26 (66.7%) were on corticosteroids during IGRA testing. A total of eight patients (20.5%) received anti-TB medications. In the positive IGRA group, the mean age was 55.7 years and the female-to-male ratio was 3:1. The most common rheumatologic condition was rheumatoid arthritis (n = 69, 56%). Sixty-five (52.8%) patients were on conventional DMARDs, 43 (34.9%) were on corticosteroids during IGRA testing, and 74 (60%) received anti-TB medications. Two cases (1.6%) of active TB infections were detected among patients with positive IGRA tests, both of whom were receiving anti-tumor necrosis factor alpha inhibitor treatment in combination with methotrexate. No cases of active TB infection were observed in the indeterminate IGRA group. Conclusion Long-term data on the risk of TB activation in positive and indeterminate IGRA results for rheumatological conditions are low. It is recommended to reassess the choice of using anti-TNF-α, with a positive IGRA result if no other feasible alternatives can be offered. Our findings stress the importance of age, underlying diseases, and immunosuppressive treatments in interpreting IGRA results and guiding patient management. A large multicenter study is needed to understand the differences and outcomes of such patients in TB endemic and nonendemic geographical areas.
