Introduction
The COVID-19 pandemic and associated preventive measures have an impact on the persons’ mental health, including increasing risk of symptoms of anxiety and depression in particular. Individual experiencing mental health difficulties in the past could be especially vulnerable during lockdown, however, few studies have tested this empirically considering preexisting mental health difficulties using longitudinal data.
ObjectivesThe objective of this study is to examine the longitudinal association between preexisting symptoms of anxiety/depression and symptoms of anxiety/depression during lockdown due to the COVID-19 pandemic in a community sample.
MethodsSeven waves of data collection were implemented from March-May 2020. Generalized estimation equations models were used to estimate the association between preexisting symptoms of anxiety/depression and symptoms of anxiety/depression during lockdown among 662 mid-aged individuals from the French TEMPO cohort.
ResultsWe found an elevated odds ratio of symptoms of anxiety/depression (OR=6.73 95% [CI=4.45–10.17]) among individuals experiencing such symptoms prior lockdown. Furthermore, the odds of symptoms of anxiety/depression during lockdown was elevated among women (OR=2.07 [95% CI=1.32–3.25]), subjects with low household income (OR=2.28 [1.29–4.01]) and persons who reported loneliness (OR=3.94 [2.47–6.28]).
ConclusionsThis study demonstrates a strong relationship between preexisting symptoms of anxiety/depression and anxiety/depression during the COVID-19 outbreak among mid-aged French adults. The findings underline the role of preexisting symptoms of anxiety/depression as a vulnerability factor of anxiety/depression during lockdown. Furthermore, the study shows that loneliness is independently associated with symptoms of anxious/depression, when controlling for prior anxiety/depression symptoms.

Introduction:
The C677T polymorphism in the folate metabolising enzyme methylenetetrahydrofolate reductase (MTHFR) is associated with hypertension. Riboflavin acts as a cofactor for MTHFR in one-carbon metabolism which generates methyl groups for utilisation in important biological reactions such as DNA methylation. Supplementation with riboflavin has previously been shown to lower blood pressure in individuals with the MTHFR 677TT genotype. The mechanism regulating this gene-nutrient interaction is currently unknown but may involve aberrant DNA methylation which has been implicated hypertension.
Objectives:The aims of this study were to examine DNA methylation of hypertension-related genes in adults stratified by MTHFR C677T genotype and the effect of riboflavin supplementation on DNA methylation of these genes in individuals with the MTHFR 677TT genotype.
Materials and Methods:We measured DNA methylation using pyrosequencing in a set of candidate genes associated with hypertension including angiotensin II receptor type 1 (AGTR1), G nucleotide binding protein subunit alpha 12 (GNA12), insulin-like growth factor 2 (IGF2) and nitric oxide synthase 3 (NOS3). Stored peripheral blood leukocyte samples from participants previously screened for the MTHFR C677T genotype who participated in targeted randomised controlled trials (1.6mg/d riboflavin or placebo for 16 weeks) at Ulster University were accessed for this analysis (n = 120).
Results:There were significant differences in baseline average methylation between MTHFR CC and TT genotypes at NOS3 (p = 0.026) and AGTR1 (p = 0.045) loci. Riboflavin supplementation in the TT genotype group resulted in altered average methylation at IGF2 (p = 0.025) and CpG site-specific alterations at the AGTR1 and GNA12 loci.
Conclusion:DNA methylation at genes related to hypertension were significantly different in individuals stratified by MTHFR genotype group. Furthermore, in MTHFR 677TT genotype individuals, there were concurrent alterations in DNA methylation at genes linked to hypertension in response to riboflavin supplementation. This is the largest study to date to demonstrate an interaction between DNA methylation of hypertension-related genes and riboflavin supplementation in adults with the MTHFR 677TT genotype. Further work using a genome-wide approach is required to better understand the role of riboflavin in altering DNA methylation in these genetically at-risk individuals.

Optimal maternal polyunsaturated fatty acid (PUFA) status is essential for foetal development. The desaturase enzymes, encoded by the fatty acid desaturase (FADS) genes, are involved in the endogenous synthesis of long chain (LC)PUFA and influence maternal LCPUFA concentrations. The minor allele of various FADS SNPs has been associated with increased maternal concentrations of the precursors linoleic acid (LA) and α-linolenic acid (ALA), and lower concentrations of the LCPUFA arachidonic acid (AA) and docosahexaenoic acid (DHA); however, there is limited research to date on the influence of FADS genotype on cord PUFA status. The aim of the current study was to investigate the influence of maternal and child genetic variation on cord blood PUFA status in a high fish-eating cohort.
Cord blood samples collected from mother-child pairs (n = 1088) taking part in the Seychelles Child Development Study (SCDS) Nutrition Cohort 2 (NC2) were analysed for total serum PUFA. Maternal (n = 1088) and child genotype (n = 592) were determined for the FADS SNPs rs174537, rs174561, rs174575, and rs3834458. Regression analysis determined associations between maternal and child FADS genotype and cord PUFA status. In all regression models, the major allele homozygote genotype for each SNP was used as the reference group.
Directions of significant associations were as predicted. In mothers, the minor allele homozygote genotype for SNPs rs174537, rs174561 and rs3834458 was associated with lower cord DHA and lower total n-3 PUFA when compared to the major allele homozygous genotype (p < 0.05 for all). The heterozygous genotype was associated with increased concentrations of LA compared to the reference genotype for rs174561 (p = 0.021) and rs383448 (p = 0.023). In children, the heterozygous genotype was associated with lower AA concentrations and lower cord n-6:n-3 ratio for all SNPs (p < 0.05 for all) compared to those with the major allele homozygous genotype. A lower cord AA:LA ratio was also observed for children heterozygous for rs174547, rs174561 and rs174575 (p < 0.05 for all). Contrary to expected, there were no associations between cord PUFA concentrations and child minor allele homozygous genotype.
The current study indicates that variation in maternal and child FADS genotype influences cord PUFA concentrations, despite the high intake of preformed dietary LCPUFA from fish in this population. The sample size for minor allele homozygous children was likely too small to observe any statistically significant associations in the current analysis. Further research is needed to determine whether increased dietary intake can compensate for lower PUFA status as a result of FADS genotype.

Objective:
Estimate the prevalence of use of psychotropic medications in the cities of São Paulo (SP) and Rio de Janeiro (RJ);
Method:Random sample of 3744 individuals, 15–75 years; CIDI 2.1 (depression and anxiety) and direct questions about use of psychotropic medications in the past year; prevalence estimation was performed by weighting oversampling in SP and standardization between cities by age; psychotropic consumption association with socio-demographic variables and diagnosis was performed by logistic regression.
Results:The prevalence of psychotropic use was 8.95% in SP (CI:7.93–9 .97) and 9:54% in RJ (CI:8.49–10 .59). Antidepressants (4.72% and 4.33%) and tranquilizers (4.20% and 1.73%) respectively in SP and RJ where more common used. Psychiatrists in SP most often prescribed psychotropic (39%), in RJ general practitioners (48.8%) where more cited. Most antipsychotics (52%) and antidepressants (39%) in SP were donated by the government in RJ this figure falls to 8% and 7%. Female individuals with increasing age, separated or divorced with a psychiatric diagnosis in the past year, family history of mental illness and higher income were more likely to use psychotropic drugs. About 70% to 82% of individuals diagnosed with major depressive disorder or phobic disorder, did not use any psychotropic drug.
Conclusion:There was a decrease in the consumption of psychotropic drugs in Brazil in recent decades, with a change in the consumption of tranquilizers and antidepressants. There is a need for a better training and education of doctors and family assistance programs in recognizing symptoms of common mental health disorders.

Epidemiological studies conducted with prisoners in several countries have shown a high prevalence of mental disorders.
ObjectiveTo determine the prevalence of psychiatric disorders in the prison population in the State of São Paulo, Brazil.
MethodsThrough stratified random sampling, 1,192 men and 617 women prisoners were evaluated for the presence of psychiatric disorders by the Composite International Diagnostic Interview, 2.1 version, according to definitions and criteria of International Classification of Diseases (ICD-10). The prevalence estimates of mental disorders and their respective 95% confidence intervals were calculated and adjusted for sample design through complex sample analysis.
ResultsLifetime and 12-month prevalence rates differed between genders. Lifetime and 12-month prevalence of any mental disorder was, respectively, 68.9% and 39.2% among women, and 56.1% and 22.1% among men. Lifetime and 12-month prevalence of anxious-phobic disorders was, respectively, 50% and 27.7% among women and 35.3% and 13.6% among men, of affective disorders was 40% and 21% among women and 20.8% and 9.9% among men, and of drug-related disorders was 25.2% and 1.6% among women and 26.5% and 1.3% among men. For severe mental disorders (psychotic, bipolar disorders, and severe depression), the lifetime and 12-month prevalence rates were, respectively, 25.8% and 14.7% among women, and 12.3% and 6.3% among men.
ConclusionsThis study, which was performed with a representative prison population, showed high rates of psychiatric disorders among men and women. Epidemiological studies on mental health needs of prisoners are crucial for planning and development of appropriate health care programs for specific prison populations.
