A systematic review of evidence-based interventions for child and adolescent mental health problems in low- and middle-income countries.

BACKGROUND: Treatments for mental health problems in childhood and adolescence have advanced in the last 15 years. Despite advances in research, most of the evidence on effective interventions comes from high-income countries, while evidence is scarce in low- and middle-income countries (LMICs), where 90% of world's children and adolescents live. The aim of this review was to identify evidence-based interventions tested in LMICs to treat or prevent child and adolescent mental health problems. METHODS: We conducted a systematic review of seven major electronic databases, from January 2007 to July 2019. We included randomised or non-randomised clinical trials that evaluated interventions for children or adolescents aged 6 to 18 years living in LMICs and who had, or were at risk of developing, one or more mental health problems. Results were grouped according to the studied conditions. Due to the heterogeneity of conditions, interventions and outcomes, we performed a narrative synthesis. The review was registered at PROSPERO under the number CRD42019129376. FINDINGS: Of 127,466 references found through our search strategy, 107 studies were included in narrative synthesis after the eligibility verification processes. Nineteen different conditions and nine types of interventions were addressed by studies included in the review. Over 1/3 of studied interventions were superior to comparators, with psychoeducation and psychotherapy having the highest proportion of positive results. One-third of studies were classified as presenting low risk of bias. INTERPRETATION: This review shows that different interventions have been effective in LMICs and have the potential to close the mental health care gap among children and adolescents in low-resource settings.

Factors associated with suicide risk among Brazilian graduate students during the COVID-19 pandemic.

Though pandemic-related suicides are a concern, little is known about factors potentially linking graduate student life and suicide risk. This study identified factors associated with suicide risk among Brazilian graduate students (N = 5,344) during the COVID-19 pandemic. Utilizing the Mini International Neuropsychiatric Interview, this study revealed that 31.5% of participants presented some risk for suicide: 16.6% "low risk," 4.7% "moderate risk," and 10.2% "high risk." Higher income and religious affiliation were identified as protective factors. Identified risk factors encompass non-heterosexual orientation, a history of depression or posttraumatic stress or common mental disorders diagnoses, the use of medications-both general and psychopharmaceuticals-without medical prescription, antipsychotics use, alcohol consumption, lack of health insurance, and dissatisfaction with life as a result of accessing social media networks. The high vulnerability of graduate students to suicide risk highlights the need for institutional suicide prevention initiatives.

Disruption by stealth - Interference of endocrine disrupting chemicals on hormonal crosstalk with thyroid axis function in humans and other animals.

Thyroid hormones (THs) are important regulators of growth, development, and homeostasis of all vertebrates. There are many environmental contaminants that are known to disrupt TH action, yet their mechanisms are only partially understood. While the effects of Endocrine Disrupting Chemicals (EDCs) are mostly studied as "hormone system silos", the present critical review highlights the complexity of EDCs interfering with TH function through their interactions with other hormonal axes involved in reproduction, stress, and energy metabolism. The impact of EDCs on components that are shared between hormone signaling pathways or intersect between pathways can thus extend beyond the molecular ramifications to cellular, physiological, behavioral, and whole-body consequences for exposed organisms. The comparatively more extensive studies conducted in mammalian models provides encouraging support for expanded investigation and highlight the paucity of data generated in other non-mammalian vertebrate classes. As greater genomics-based resources become available across vertebrate classes, better identification and delineation of EDC effects, modes of action, and identification of effective biomarkers suitable for HPT disruption is possible. EDC-derived effects are likely to cascade into a plurality of physiological effects far more complex than the few variables tested within any research studies. The field should move towards understanding a system of hormonal systems' interactions rather than maintaining hormone system silos.

IL-10 (-819C/T), TNFA (-30G/A) and ENOS (-786T/C) Polymorphisms Modulating the Outcome Related to Mental Disorders in Crack Addicted Users.

Background: Cocaine/crack use affects immune system molecules and development of mental disorders has been identified. Objective: To investigate the relationship of polymorphisms in the TNFA (-308G/A), IL-10 (-819C/T) and ENOS (-786T/C) genes with mental disorders in cocaine and crack users. Methods: A case-control study was carried out, which included 107 cocaine and crack users and 115 controls who never used healthy cocaine and crack. The SNPs in the TNFA (-308G/A), IL-10 (-819C/T) and ENOS (-786T/C) genes were genotyped by real time PCR. Results: As for the individuals included in this study, the average age of 31.4 years (± 8.59). We identified that the G/A genotype to TNFA (-308) (OR = 0.24; p = 0.03) and the A allele (OR = 0.30; p = 0.03) were associated with reduced risk for dysthymic disorder. The T allele of the IL-10 (-819) polymorphism was associated with decreased risk of developing panic disorder (OR = 0.44; p = 0.01), while the C allele was correlated with an increased risk for alcohol dependence (OR = 1.97; p = 0.04), alcohol abuse (OR = 1.81; p = 0.04) and psychotic syndrome (OR = 2.23; p = 0.01). C/C genotype was correlated with increased chances of developing current psychotic syndrome (OR = 4.23; p = 0.01). Conclusion: Our results suggest that genetic polymorphisms promote susceptibility or promote protection for clinical phenotypes of psychiatric comorbidities in cocaine and crack users and be considered as good prognostic markers.

Host behaviour alteration by its parasite: from brain gene expression to functional test.

Many parasites with complex life cycles modify their intermediate hosts' behaviour, presumably to increase transmission to their final host. The threespine stickleback (Gasterosteus aculeatus) is an intermediate host in the cestode Schistocephalus solidus life cycle, which ends in an avian host, and shows increased risky behaviours when infected. We studied brain gene expression profiles of sticklebacks infected with S. solidus to determine the proximal causes of these behavioural alterations. We show that infected fish have altered expression levels in genes involved in the inositol pathway. We thus tested the functional implication of this pathway and successfully rescued normal behaviours in infected sticklebacks using lithium exposure. We also show that exposed but uninfected fish have a distinct gene expression profile from both infected fish and control individuals, allowing us to separate gene activity related to parasite exposure from consequences of a successful infection. Finally, we find that selective serotonin reuptake inhibitor-treated sticklebacks and infected fish do not have similarly altered gene expression, despite their comparable behaviours, suggesting that the serotonin pathway is probably not the main driver of phenotypic changes in infected sticklebacks. Taken together, our results allow us to predict that if S. solidus directly manipulates its host, it could target the inositol pathway.

Meta-Analysis of the Relationship between TNF-α (-308G/A) and IL-10 (-819C/T) Gene Polymorphisms and Susceptibility to Dengue.

OBJECTIVE: This study determined whether tumor necrosis factor alpha (TNF-α) and Interleukin-10 (IL-10) polymorphisms are associated with susceptibility to dengue. METHODS: a systematic review with meta-analysis was conducted of the associations between the TNF-α (-308G/A) and IL-10 (-819C/T) polymorphisms and dengue. RESULTS: A total of eight case-controls studies involving 384 individuals with symptomatic dengue, 571 individuals with dengue hemorrhagic fever, and 995 healthy controls were considered in the meta-analysis. There was no significant association between TNF-α (-308G/A) and IL-10 (-819C/T) polymorphism and dengue in overall population. However, stratifying meta-analysis by groups, the meta-analysis revealed association between the TNF-α -308 G/G (OR: 1.62, CI: 1.02-2.57, p = 0.04) genotype and allele G (OR: 1.62, CI: 1.04-2.55, p = 0.03) that confers susceptibility to symptomatic dengue, while the TNF-α -308 G/A genotype (OR: 0.69, CI = 0.39-0.99, p = 0.04) and allele A (OR: 0.64, CI: 0.41-1.00, p = 0.05) confers protection to symptomatic dengue. No difference was observed for the TNF-α (-308) and IL-10 (-819C/T) polymorphisms in the comparisons of hemorrhagic dengue versus control and hemorrhagic dengue versus symptomatic dengue. CONCLUSION: This meta-analysis showed that TNF-α (-308) polymorphism is associated with dengue symptomatic susceptibility.

Finding Rare, Disease-Associated Variants in Isolated Groups: Potential Advantages of Mennonite Populations.

Large-scale genotyping and next-generation sequencing techniques have allowed great advances in the field of molecular genetics. Numerous common variants of low impact have been associated with many complex human traits and diseases, such as bipolar disorder and schizophrenia. Although they may exert a greater impact on risk, few rare disease variants have been found, owing to the greatly increased sample sizes that are typically necessary to demonstrate association with rarer variants. One alternative strategy is to study isolated populations, where historical bottlenecks reduce genetic diversity and some otherwise rare variants may drift to higher frequencies. Here we describe the Mennonite population settlements, considering their history of multiple bottlenecks followed by demographic expansion and a currently widespread geographical distribution. We argue that Mennonite populations are valuable partners for studies seeking genetic variants that exert a high impact on risk for a variety of common disorders, including mental illnesses.

Health promotion of Street Clinic workers: convergent care research.

OBJECTIVE: To develop a health promotion action for Street Clinic workers. METHOD: Qualitative research which used the Convergent Care Research methodology. The data collection was conducted through participant observation and convergence groups, from May to October 2021, with 39 workers from six teams of the Street Clinic. Data analysis followed the stages of apprehension, synthesis, theorization, and transfer. RESULTS: Some integrativepractices such as, stretching, group dynamics, dance, music, massage and cinema were suggested as interventions to be implemented. Given the need, Reichian stretching was developed as an intervention which favored body awareness, promoting the well-being of workers. CONCLUSION: The workers presented a conception of health promotion related to access to services and guarantee of rights. Reichian stretching provided a space for care and reflection on caring and respecting limits, favoring the body awareness and promoting relaxation.

ATP sulfurylase atypical leucine zipper interacts with Cys3 and calcineurin A in the regulation of sulfur amino acid biosynthesis in Cryptococcus neoformans.

Fungal pathogens are a major cause of death, especially among immunocompromised patients. Therapies against invasive fungal infections are restricted to a few antifungals; therefore, novel therapies are necessary. Nutritional signaling and regulation are important for pathogen establishment in the host. In Cryptococcus neoformans, the causal agent of fungal meningitis, amino acid uptake and biosynthesis are major aspects of nutritional adaptation. Disruptions in these pathways lead to virulence attenuation in an animal model of infection, especially for sulfur uptake and sulfur amino acid biosynthesis. Deletion of Cys3, the main transcription factor that controls these pathways, is the most deleterious gene knockout in vitro and in vivo, making it an important target for further application. Previously, we demonstrated that Cys3 is part of a protein complex, including calcineurin, which is necessary to maintain high Cys3 protein levels during sulfur uptake and sulfur amino acid biosynthesis. In the current study, other aspects of Cys3 regulation are explored. Two lines of evidence suggest that C. neoformans Cys3 does not interact with the F-box WD40 protein annotated as Met30, indicating another protein mediates Cys3 ubiquitin degradation. However, we found another level of Cys3 regulation, which involves protein interactions between Cys3 and ATP sulfurylase (MET3 gene). We show that an atypical leucine zipper at the N-terminus of ATP sulfurylase is essential for physical interaction with Cys3 and calcineurin. Our data suggests that Cys3 and ATP sulfurylase interact to regulate Cys3 transcriptional activity. This work evidences the complexity involved in the regulation of a transcription factor essential for the sulfur metabolism, which is a biological process important to nutritional adaptation, oxidative stress response, nucleic acid stability, and methylation. This information may be useful in designing novel therapies against fungal infections.

Psychopathological symptoms and work status of Southeastern Brazilian nursing in the context of COVID-19. / Sintomas psicopatológicos e situação laboral da enfermagem do Sudeste brasileiro no contexto da COVID-19.

OBJECTIVE: to evaluate the relationship between psychopathological symptoms and the work situation of nursing professionals in the Southeast Region, Brazil, in the context of the COVID-19 pandemic. METHOD: an observational and cross-sectional study with virtual and snowball data collection from April to July 2020. A questionnaire containing socio-demographic and labor data and the psychopathological symptoms assessment scale (psychoticism, obsessiveness/compulsivity, somatization, and anxiety) were applied. Descriptive and inferential statistics were used to analyze the data. RESULTS: among the 532 participants, there was a relationship between weekly workload and psychoticism. All domains of the scale were associated with embarrassment and/or violence in the course of work and receiving psychological/emotional support from the institution where the individual works/studies. CONCLUSION: the age group, heavy workload, experienced violence and lack of psychological support during the pandemic were associated with increased psychopathological symptoms among nursing professionals. It is suggested the creation of institutional guidelines aimed at the reception and follow-up of these demands.

The Role of the IL-10 (-819C/T), TNFA (-308G/A) and ENOS (-786T/C) Polymorphisms of Impulsive and Aggressive Personality Traits in Cocaine/Crack Users.

Cytokines and nitric oxide have been associated with impulsive and aggressive personality traits. We conducted the first study that investigated the role of SNPs in cytokines and nitric oxide genes and the influence in the progression of aggressive and impulsive behavior in 107 of cocaine and crack users. In this case-control, IL-10 (-819C/T), TNFA (-308G/A) and ENOS (-786T/C) polymorphisms were determined by Real-Time PCR. In addition, the relationship between these polymorphisms and Impulsivity and Aggression was determined. We found that the physical aggressiveness sub score was negatively correlated with the C allele of -819C/T polymorphism of the IL-10 (b = -0.14; p = 0.04). The T allele of the SNP -786T/C of the ENOS gene positively predicts traits of physical aggressiveness (b = 0.14; p = 0.04). The GA genotype (b = 0.22; p = 0.01) and the A allele (b = 0.15; p = 0.02) of -308 G/A polymorphism of the TNFA were positively correlated with aggressiveness physical. The GA genotype (b = 0.20; p = 0.03) was positively correlated with aggressiveness verbal. IL-10 (-819C/T), TNFA (-308G/A) and ENOS (-786T/C) polymorphisms might be associated with high risk of aggressive and impulsive behavior.

Association of polymorphisms in serotonin and nitric oxide genes with clinical outcome of dengue in Brazilian northeast population.

Serotonin and nitric oxide seem to be involved in Dengue virus infection. The aim of this study was to investigate if SNPs in serotonin and nitric oxide are associated with dengue severity. A retrospective case-control study was conducted, with groups of dengue fever (DF; n = 78) and dengue hemorrhagic fever patients (DHF; n = 49). Genotyping was performed using qPCR and PCR. The power of the sample size was calculated by G*power software. The heterozygous SL for 5-HTTLPR SNP was significantly correlated with protection against progression to DHF in the codominant SS/SL/LL (OR = 0.22, 95% CI = 0.06-0.81, p = 0.011) and overdominant models SL vs SS + LL (OR = 0.19, 95% CI = 0.06-0.65, p = 0.003). For the ENOS (rs1799983) SNP, the genotype GT was positively associated with protection for development of the clinical form in DHF compared to dengue fever (OR = 0.39, 95% CI = (0.13-1.14), p = 0.0058) in codominant GG/GT/TT and overdominant model GT vs GG + TT (OR = 0.35, 95% CI = (0.12-1.02), p = 0.04). To our knowledge, this is the first study to identify the association of the serotonin and nitric oxide SNPs with dengue severity.

Trends in suicide attempts at an emergency department.

Objective: To characterize the profile of suicide attempts treated at an emergency department in the municipality of Arapiraca, state of Alagoas, Brazil, from 2009 to 2012. Methods: We analyzed all emergency department records containing a diagnosis of suicide attempt. Data were evaluated using Student's t test and Pearson's chi-square test. Significance was accepted at p<0.05. Results: We identified 2,142 cases. Suicide attempts were more frequent among women and young adults, but deaths were more frequent among men. Suicide attempts were most frequent among patients aged 10 to 39 years (81.1%). Drug intoxication (65.0%) and non-drug poisoning (16.2%) were significantly more prevalent than other methods of suicide. The month of April (10.6%) accounted for the greatest number of cases, and July had the smallest number (5.5%). Suicide attempts were most prevalent in spring (28.3%), on Sundays (18.4%) and Saturdays (16.8%), and from 12:00 p.m. to 5:59 p.m. Conclusion: Suicide prevention measures should focus on young women. Further research into the care provided to suicide attempters and better monitoring of the sale and use of medicines and poisons could be useful.

Suicide attempt in mental disorders (MeDi): Association with 5-HTT, IL-10 and TNF-alpha polymorphisms.

BACKGROUND: Mental disorders (MeDi) and suicide attempts (SA) are influenced by environmental and genetic factors. Genetic polymorphism studies have identified some candidate genes for suicidal behaviour in people with MeDi. OBJECTIVE: To evaluate MeDi and SA in relation to the presence of rs2020933 (5-HTT), rs1800871 (IL-10) and rs1800629 (TNF-α) polymorphisms. METHODS: A questionnaire for identification and general data, a brief quality of life assessment (WHOQOL-brief), the scale of suicide ideation by Beck and the MINI International Neuropsychiatric Interview were used in this study. DNA was obtained using buccal mucosa swab samples, and genotyping was performed using real-time polymerase chain reaction. A total of 306 patients were assessed with MeDi; 161 patients had MeDi and a history of SA, and 145 patients had MeDi and no history of SA. The study had 175 subjects in the control group. RESULTS: The TNF-α rs1800629 -308A/G genotype was significantly associated with function as a protection factor in the control group compared with MeDi without SA. The TNF-α rs1800629 -308G allele appeared as risk factor for MeDi compared to the control group, for female gender. Additionally, the -308A/G + A/A genotype appeared as protection factor for the control group compared to the group with MeDi. For TNF-α, the -308G allele appeared as risk factor for the number of SA (1 time) compared to the control group. CONCLUSION: The IL-10 (rs1800871) and 5-HTT (rs2020933) SNPs were considered to have inadequate statistical power. The rs1800629 (TNF-α) polymorphism may be associated with MeDi without SA, MeDi in females and the number of SA (1 time) in the studied group.

Evaluation of the quality of life and risk of suicide.

OBJECTIVE: To identify the socio-demographic profiles, suicidal ideation, the presence of mental disorders and the quality of life of patients using mental health services in Arapiraca, Alagoas, Brazil. METHOD: Interviews were conducted in family health units and the Psychosocial Attention Center. The sample included 202 mental disorder patients with a risk of suicide attempts, 207 mental disorder patients without a risk of suicide attempts and 196 controls. This study used an identification questionnaire, the abbreviated World Health Organization Quality of Life questionnaire, Beck's Suicidal Ideation Scale and the Mini International Neuropsychiatric Interview. RESULTS: Patients who had a mental disorder and a risk of suicide attempts tended to be single, had less education and lower family income, were not working and showed lower scores in quality of life domains; 73 of these patients had suicidal ideation in the previous week. Depressive disorders, manic episodes, hypomanic episodes, social phobias, obsessive compulsive disorder, post-traumatic stress disorder, psychotic syndromes and generalized anxiety disorder were more frequent and statistically significant for patients at risk for suicide attempts. CONCLUSION: The management of patients with a risk of suicide attempts must focus on individual patients because this risk is directly linked to changes in quality of life and the improvement of these patients' prognosis.

Do suicide attempts occur more frequently in the spring too? A systematic review and rhythmic analysis.

BACKGROUND: Seasonal variations in suicides have been reported worldwide, however, there may be a different seasonal pattern in suicide attempts. The aim of this study was to perform a systematic review on seasonality of suicide attempts considering potential interfering variables, and a statistical analysis for seasonality with the collected data. METHOD: Observational epidemiological studies about seasonality in suicide attempts were searched in PubMed, Web of Science, LILACS and Cochrane Library databases with terms attempted suicide, attempt and season. Monthly or seasonal data available were evaluated by rhythmic analysis softwares. RESULTS: Twenty-nine articles from 16 different countries were included in the final review. It was observed different patterns of seasonality, however, suicide attempts in spring and summer were the most frequent seasons reported. Eight studies indicated differences in sex and three in the method used for suicide attempts. Three articles did not find a seasonal pattern in suicide attempts. Cosinor analysis identified an overall pattern of seasonal variation with a suggested peak in spring, considering articles individually or grouped and independent of sex and method used. A restricted analysis with self-poisoning in hospital samples demonstrated the same profile. LIMITATIONS: Grouping diverse populations and potential analytical bias due to lack of information are the main limitations. CONCLUSIONS: The identification of a seasonal profile suggests the influence of an important environmental modulator that can reverberate to suicide prevention strategies. Further studies controlling interfering variables and investigating the biological substrate for this phenomenon would be helpful to confirm our conclusion.

Inhibitory effects of glycoprotein IIb/IIIa antagonists and aspirin on the release of soluble CD40 ligand during platelet stimulation.

BACKGROUND: Glycoprotein (GP) IIb/IIIa antagonists inhibit platelet aggregation, an activity attributed to the clinical benefits of these drugs in settings that involve acute coronary thrombosis. However, platelet activation and subsequent aggregation are now known to cause the release of a soluble form of CD40 ligand (sCD40L), a prothrombotic and proinflammatory protein with GP IIb/IIIa binding activity and an established role in atherosclerotic lesion progression. The present study was designed to determine what effect GP IIb/IIIa antagonists have on the release of sCD40L. METHODS AND RESULTS: Doses of eptifibatide, abciximab, and tirofiban that inhibited platelet aggregation by at least 80% also inhibited sCD40L release in vitro (by 85%, 57%, and 80%, respectively). When platelets were stimulated with a thrombin receptor agonist, inhibition by GP IIb/IIIa antagonists occurred without affecting the release of betaTG, an alpha-granule protein. Unexpectedly, concentrations of the 3 antagonists that blocked aggregation by only 20% to 50% potentiated the release of sCD40L (by 19% to 26%). Platelets from aspirin-treated individuals were partially protected from sCD40L release, but only when the agonist was collagen, an affect augmented by the addition of GP IIb/IIIa antagonists. CONCLUSIONS: These studies suggest that the mechanisms responsible for the clinical benefits of GP IIb/IIIa antagonists (at doses that optimally inhibit aggregation) and of aspirin may not be limited to the inhibition of thrombosis through their blockade of platelet aggregation but may also involve the inhibition of inflammation and thrombosis through their blockade of sCD40L release. These studies also provide a mechanism by which suboptimal doses of GP IIb/IIIa antagonists may be proinflammatory.
