Adaptation and validation of the Patient Health Questionnaire-9 to evaluate major depression in a primary care sample in Latvia

<p><b>Background:</b> Depression is one of the most common mental disorders in primary care settings and is often underdiagnosed and undertreated by general practitioners (GPs). To date, no depression screening instruments have been validated for use in primary care settings in Latvia. The aim of this study was to establish the validity and cutoff score of the Patient Health Questionnaire-9 (PHQ-9) among primary care patients in Latvia.</p> <p><b>Materials and methods:</b> During a one-week period, all consecutive patients aged 18 years or older visiting their GP of health concerns at 6 primary care settings were invited to complete the PHQ-9 questionnaire in their native language (Latvian or Russian). Criterion validity was assessed against the Mini International Neuropsychiatric Interview (M.I.N.I.), which was conducted over the telephone by a psychiatrist less than 2 weeks after a primary care physician visit.</p> <p><b>Results:</b> In total, 324 patients were evaluated using the PHQ-9, 272 of whom agreed to be interviewed with the M.I.N.I. Overall, the PHQ-9 items showed good internal (Cronbach’s alpha 0.84) reliability. A cutoff score of 10 was established for the PHQ-9 (sensitivity 86.49%, specificity 89.36%), correctly classifying 86.4% of patients with current depression.</p> <p><b>Conclusions:</b> The PHQ-9 appears to be a reliable and valid instrument that can be used to diagnose major depression among Latvian and Russian speaking adults at the primary care level.</p

DataSheet_1_New-onset psychosis following COVID-19 vaccination: a systematic review.pdf

BackgroundThe emergence of a new coronavirus strain caused the COVID-19 pandemic. While vaccines effectively control the infection, it’s important to acknowledge the potential for side effects, including rare cases like psychosis, which may increase with the rising number of vaccinations.ObjectivesOur systematic review aimed to examine cases of new-onset psychosis following COVID-19 vaccination.MethodsWe conducted a systematic review of case reports and case series on new-onset psychosis following COVID-19 vaccination from December 1st, 2019, to November 21st, 2023, using PubMed, MEDLINE, ClinicalKey, and ScienceDirect. Data extraction covered study and participant characteristics, comorbidities, COVID-19 vaccine details, and clinical features. The Joanna Briggs Institute quality assessment tools were employed for included studies, revealing no significant publication bias.ResultsA total of 21 articles described 24 cases of new-onset psychotic symptoms following COVID-19 vaccination. Of these cases, 54.2% were female, with a mean age of 33.71 ± 12.02 years. Psychiatric events were potentially induced by the mRNA BNT162b2 vaccine in 33.3% of cases, and psychotic symptoms appeared in 25% following the viral vector ChAdOx1 nCoV-19 vaccine. The mean onset time was 5.75 ± 8.14 days, mostly reported after the first or second dose. The duration of psychotic symptoms ranged between 1 and 2 months with a mean of 52.48 ± 60.07 days. Blood test abnormalities were noted in 50% of cases, mainly mild to moderate leukocytosis and elevated C-reactive protein. Magnetic resonance imaging results were abnormal in 20.8%, often showing fluid-attenuated inversion recovery hyperintensity in the white matter. Treatment included atypical antipsychotics in 83.3% of cases, typical antipsychotics in 37.5%, benzodiazepines in 50%, 20.8% received steroids, and 25% were prescribed antiepileptic medications. Overall, 50% of patients achieved full recovery.ConclusionStudies on psychiatric side effects post-COVID-19 vaccination are limited, and making conclusions on vaccine advantages or disadvantages is challenging. Vaccination is generally safe, but data suggest a potential link between young age, mRNA, and viral vector vaccines with new-onset psychosis within 7 days post-vaccination. Collecting data on vaccine-related psychiatric effects is crucial for prevention, and an algorithm for monitoring and treating mental health reactions post-vaccination is necessary for comprehensive management.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO, identifier CRD42023446270.</p

Data_Sheet_1_Students' mental health during the pandemic: results of the observational cross-sectional COVID-19 MEntal health inTernational for university Students (COMET-S) study.docx

IntroductionThe aim of the study was to search rates of depression and mental health in university students, during the COVID-19 pandemic.Materials and methodsThis is an observational cross-sectional study. A protocol gathering sociodemographic variables as well as depression, anxiety and suicidality and conspiracism was assembled, and data were collected anonymously and online from April 2020 through March 2021. The sample included 12,488 subjects from 11 countries, of whom 9,026 were females (72.2%; aged 21.11 ± 2.53), 3,329 males (26.65%; aged 21.61 ± 2.81) and 133 “non-binary gender” (1.06%; aged 21.02 ± 2.98). The analysis included chi-square tests, correlation analysis, ANCOVA, multiple forward stepwise linear regression analysis and Relative Risk ratios.ResultsDysphoria was present in 15.66% and probable depression in 25.81% of the total study sample. More than half reported increase in anxiety and depression and 6.34% in suicidality, while lifestyle changes were significant. The model developed explained 18.4% of the development of depression. Believing in conspiracy theories manifested a complex effect. Close to 25% was believing that the vaccines include a chip and almost 40% suggested that facemask wearing could be a method of socio-political control. Conspiracism was related to current depression but not to history of mental disorders.DiscussionThe current study reports that students are at high risk for depression during the COVID-19 pandemic and identified specific risk factors. It also suggested a role of believing in conspiracy theories. Further research is important, as it is targeted intervention in students' groups that are vulnerable both concerning mental health and conspiracism.</p
