Association of Major Disease Outbreaks With Adolescent and Youth Mental Health in Low- and Middle-Income Countries: A Systematic Scoping Review.

Importance: Adolescents and young people have been historically understudied populations, and previous studies indicate that during epidemics, these populations, especially in low- and middle-income countries (LMICs), are at high risk of developing mental disturbances. Objective: To identify the existing evidence regarding the association of mental health with outbreaks of the influenza A (H1N1), Zika, Ebola, and SARS-CoV-2 virus in exposed youth and adolescents in LMICs. Evidence Review: Across 6 databases (Embase, Cochrane Library, PubMed, PsycINFO, Scopus, and Web of Science), the mental health outcomes of adolescents and youth (aged 10-24 years) associated with 4 major pandemic outbreaks from January 2009 to January 2021 in LMICs were reviewed. A group of 3 authors at each stage carried out the screening, selection, and quality assessment using Joanna Briggs Institute checklists. The social determinants of adolescent well-being framework was used as a guide to organizing the review. Findings: A total of 57 studies fulfilled the search criteria, 55 related to the SARS-CoV-2 (COVID-19) pandemic and 2 covered the H1N1 influenza epidemics. There were no studies associated with Zika or Ebola outbreaks that met screening criteria. The studies reported high rates of anxiety and depressive symptoms among adolescents, including posttraumatic stress disorder, general stress, and health-related anxiety. Potential risk factors associated with poor mental health outcomes included female sex; home residence in areas with strict lockdown limitations on social and physical movement; reduced physical activity; poor parental, family, or social support; previous exposure to COVID-19 infection; or being part of an already vulnerable group (eg, previous psychiatric conditions, childhood trauma, or HIV infection). Conclusions and Relevance: Results of this systematic scoping review suggest that the COVID-19 pandemic and H1N1 epidemic were associated with adverse mental health among adolescents and youth from LMICs. Vulnerable youth and adolescents may be at higher risk of developing mental health-related complications, requiring more responsive interventions and further research. Geographically localized disease outbreaks such as Ebola, Zika, and H1N1 influenza are highly understudied and warrant future investigation.

Application of cinnarizine in migraine prevention: A systematic review and meta-analysis.

OBJECTIVE: To investigate and analyze the available data on the prophylactic effectiveness of cinnarizine in migraine disorder. BACKGROUND: Cinnarizine has demonstrated encouraging potential in preventing the attacks of migraine. Therefore, we opted to evaluate whether its sole administration leads to positive outcomes. METHODS: The PubMed, Scopus, Web of Science, and Embase databases were searched for English-only original interventional studies published until April 2022, then screened for relevancy and eligibility. The resulting data from the included studies, including the primary (ie, headache episode frequency, intensity, duration, monthly timing, and analgesic intake frequency) and secondary (ie, reported adverse events, quality of life, and activities of daily living) outcome changes compared to placebo and active controls (e.g., sodium valproate and propranolol) were then recorded by two independent assessors. Ultimately, these data were synthesized qualitatively and quantitatively (achieved by determining the mean difference via the random-effects model). RESULTS: A total of 10 studies comprising seven randomized controlled trials and three quasi-experimental studies were included. Compared to placebo, cinnarizine demonstrated significant improvements in migraine episode frequency (Mean difference = -3.10; Confidence interval = [-3.33, -2.88]; p-value < 0.001; I2  < 0.001%), and intensity (Mean difference = -1.54; Confidence interval = [-2.08, -0.99]; p-value < 0.001; I2  < 37.97%). Moreover, cinnarizine led to similar or better results when compared to active controls, including sodium valproate, topiramate, and propranolol. CONCLUSIONS: Cinnarizine can be considered a safe and effective medication for migraine prophylaxis. However, the relatively small sample size made reaching a definite conclusion impossible. Therefore, a higher number of randomized controlled trials are recommended to be taken place to clarify the situation further.

A follow-up study of patients with COVID-19 presenting with seizures.

OBJECTIVE: We performed a follow-up study of patients with COVID-19 presenting with seizures. METHODS: All consecutive patients with seizures, who were referred to Namazee Hospital, Shiraz, Iran, with a diagnosis of COVID-19, from 10 August 2020 until 20 October 2020 were included in this longitudinal study. The clinical data were collected by the admitting physician. In a follow-up phone call to the discharged patients (after eight weeks or more), we inquired their seizure outcome. RESULTS: In total, 32 patients were studied; 28 patients were followed. Twelve patients (37.5%) presented with a single tonic-clonic seizure and nine (28.1%) had convulsive status epilepticus; one patient had functional (psychogenic) seizures. Ten patients (31.3%) had pre-existing epilepsy, eight others (25%) had pre-existing CNS problems (without epilepsy), one person (3.1%) had pre-existing functional seizures, and 13 individuals (40.1%) neither had epilepsy nor had other CNS problems. Eight patients (28.6%) reported experiencing seizure(s) after being discharged from the hospital; six of these had pre-existing epilepsy and one had pre-existing functional seizures. One patient, who had a newly developed ischemic brain infarction, reported experiencing recurrent seizures. CONCLUSION: Seizures in patients with COVID-19 are either acute symptomatic (in about two-thirds) or an exacerbation of a pre-existing epilepsy/functional seizures (in about one-third). A thorough investigation of the underlying etiology of seizures in patients with COVID-19 is necessary. Seizure outcome in patients, who are hospitalized with COVID-19 and seizures, is generally good.
