RESUMO

BACKGROUND: The WHO identifies climate change as the most significant threat to global health systems. Indigenous peoples, whose lives are deeply intertwined with nature, are particularly vulnerable to the impacts of these changes. OBJECTIVE: This study aimed to understand the perspectives of Indigenous stakeholders and public services managers on the interconnectedness of climate change and Indigenous health. DESIGN: A qualitative study with 22 Indigenous stakeholders and public service managers on climate change and perceived impact on Indigenous health. SETTING AND PARTICIPANTS: Indigenous stakeholders and public service managers on climate change and perceived impact on Indigenous health from Brazil. Data was collected through interviews incorporating two vignette videos depicting environmental and health scenarios. Thematic content analysis was used to analyse the data. RESULTS: The analytical process yielded six subcategories that were further grouped into three overarching thematic macro-categories: environmental degradation and climate change in the context of Indigenous peoples; environment, vulnerability and impact on Indigenous mental health; and actions and public health policies for Indigenous peoples. CONCLUSION: The perspectives of Indigenous stakeholders and public service managers on the interconnectedness of climate change and Indigenous health were deeply entrenched in their lived experiences of loss of their lands from deforestation and environmental degradation. They argued strongly for the strengthening of public health policies aimed at the Indigenous peoples, to face many challenges, especially suicide, and to have a voice in decision-making. A sensitive approach that values Indigenous peoples' connections with nature is fundamental to promote their health and well-being.

RESUMO

During the COVID-19 pandemic, many patients in intensive care units (ICUs) were affected by invasive fungal infections, including aspergillosis, contributing to a high mortality rate. Diagnosing proven COVID-19-associated pulmonary aspergillosis (CAPA) requires clinical and radiological evaluations, along with laboratory testing of bronchoalveolar lavage samples or lung biopsies. However, these procedures and equipment are often inaccessible in developing countries or regions with limited resources, including Brazil. Consequently, alternative diagnostic methods, such as measuring Aspergillus galactomannan (GM) in tracheal aspirate (TA), have been explored for CAPA diagnosis. Nonetheless, research on the efficacy of TA-based diagnostic tests is limited. This study aimed to assess the performance of the IMMY® Sona Aspergillus lateral flow assay (LFA) for GM detection in TA samples from 60 ICU patients with suspected CAPA at two tertiary hospitals in Campo Grande, Brazil. The ELISA method (Platelia Aspergillus AG, Bio-Rad®) was used to detect Aspergillus GM in TA samples, serving as the microbiological criterion and reference test. Fifteen patients (12.4%) were identified as having possible CAPA. The overall accuracy of LFA was 94%, and the tests demonstrated an agreement of 93.1% (Cohen's kappa of 0.83). Based on our findings, the LFA for Aspergillus GM detection in TA samples exhibited excellent performance, proving to be a valuable diagnostic tool for potential CAPA. In a systematic review, two studies were included, and the meta-analysis revealed pooled estimates provided a sensitivity of 86% (95% CI, 80%-91%) and specificity of 93% (95% CI, 86%-97%). The diagnostic odds ratio (DOR) for identification of Aspergillus using LFA was 103.38 (95% CI, 38.03-281.03). Despite its lower sensitivity compared to our study, the LFA appears to be a promising diagnostic option for CAPA, particularly in suspected cases that have not received antifungal therapy. This enables timely antifungal treatment and could reduce mortality rates in regions where bronchoscopy is unavailable or limited.

RESUMO

OBJECTIVE: The objective of this study is to evaluate the association of disciplinary actions by regulatory councils and unprofessional behaviour during medical graduation. METHODS: A search strategy was developed using the terms: 'physicians', 'disciplinary action', 'education', 'medical', 'undergraduate' and their synonyms, subsequently applied to the electronic databases MEDLINE, Embase, Cochrane Library, LILACs and grey literature, with searches up to November 2023. The risk of bias was assessed using the Newcastle-Ottawa scale and statistical analysis was performed using the RevMan software. RESULTS: A total of 400 studies were found in the databases, and 15 studies were selected for full-texting reading. Four studies met the inclusion criteria and were included, bringing together a total of 3341 evaluated physicians. Three studies were included in the meta-analysis, showing a greater chance of disciplinary actions among physicians who exhibited unprofessional behaviour during medical graduation (OR: 2.54; 95%CI: 1.87-3.44; I2: 0%; P < 0.0001; 3077 participants; physicians with disciplinary action: 107/323; control physicians: 222/2754). CONCLUSIONS: There is a statistically significant association between unprofessional behaviour during medical undergraduate study and subsequent disciplinary actions by Medical Councils. The tools for periodic assessments of student behaviour during undergraduate studies can be a perspective for future studies aimed at reducing disciplinary actions among physicians.

RESUMO

Cervical cancer is the third most common gynecological cancer worldwide. Its origin is linked to intraepithelial lesions caused by high-risk Human Papillomavirus (HPV) types, detected in 99.7% of cases. Early screening is essential to prevent cancer development from these lesions. Molecular methods are more specific and offer the possibility of being performed through a self-collected sample by the patient, thus contributing to increasing screening coverage for this pathology. This study aim was to map the medical-scientific literature on existing protocols for self-sampling for HPV testing in cervical cancer screening. A search strategy was developed using the following keywords and their synonyms: "self-sampling," "professional sampling," and "HPV", on the databases: MEDLINE, Cochrane Library, Virtual Health Library - BVS, Scopus, National Institute for Health Research NHS EED, Web of Science, and EMBASE. The search strategy was formulated to identify relevant studies and describe their main characteristics, such as patient acceptance of self-sampling, cost differences between the tests used, and the accuracy of self-sampling compared to the gold standard test. A total of 876 studies were found, and 33 of those studies were included in this review. Out of these, 10 studies were domized clinical trials involving 46,751 patients, and 23 observational studies included 142,795 patients. Regarding acceptance, most studies reported a preference for self-sampling. Sensitivity analyses from various studies also showed that the low cost of self-sampling kits generally increased cost-effectiveness. The study concluded that using HPV testing on self-collected samples is a viable strategy for monitoring women with HPV.

RESUMO

BACKGROUND: There is no consensus on how to best quantify disease severity in infants with respiratory syncytial virus (RSV) and/or bronchiolitis; this lack of a sufficiently validated score complicates the provision of clinical care and, the evaluation of trials of therapeutics and vaccines. The ReSVinet score appears to be one of the most promising; however, it is too time consuming to be incorporated into routine clinical care. We aimed to develop and externally validate simplified versions of this score. METHODS: Data from a multinational (the Netherlands, Spain, and United Kingdom) multicenter case-control study of infants with RSV were used to develop simplified versions of the ReSVinet score by conducting a grid search to determine the best combination of equally weighted parameters to maximize for the discriminative ability (measured by area under the receiver operating characteristic curve [AUROC]) across a range of outcomes (hospitalization, intensive care unit admission, ventilation requirement). Subsequently discriminative validity of the score for a range of secondary care outcomes was externally validated by secondary analysis of datasets from Rwanda and Colombia. RESULTS: Three candidate simplified scores were identified using the development dataset; they were excellent (AUROC >0.9) at discriminating for a range of outcomes, and their performance was not significantly different from the original ReSVinet score despite having fewer parameters. In the external validation datasets, the simplified scores were moderate to excellent (AUROC, 0.7-1) across a range of outcomes. In all outcomes, except in a single dataset for predicting admission to the high-dependency unit, they performed at least as well as the original ReSVinet score. CONCLUSIONS: The candidate simplified scores developed require further external validation in larger datasets, ideally from resource-limited settings before any recommendation regarding their use.

RESUMO

OBJECTIVE: To evaluate the relationship between fungal infection in the female genital tract and infertility. DATA SOURCES: A systematic review was carried out, and the search was conducted in Medline, Embase, Web of Science, Google Scholar, and Cochrane Library databases until August 2022. The search strategy used standardized keywords such as "candidiasis" and "infertility," combined with their respective synonyms. The search was limited to human studies, with no language restrictions. STUDY ELIGIBILITY CRITERIA: Primary articles that evaluated women of reproductive age with and without infertility and related to the presence or absence of candidiasis were included. STUDY APPRAISAL AND SYNTHESIS METHODS: For the analyses, the odds ratio association measure was used with a confidence interval of 95% using RevMan software (version 5.4). RESULTS: Eight studies, published between 1995 and 2021 in different countries around the world, were included in this systematic review. Two studies were excluded after sensitivity analysis. A total of 909 participants were included in the group of infertile women and 2363 women in the control group. The age of the evaluated women varied between 18 and 50 years. The random effect model was used and showed no significant difference when comparing candidiasis between fertile and infertile women (odds ratio: 1.44; 95% confidence interval 0.86, 2.41 p= 0.17). CONCLUSIONS: There was no association between candidiasis and female sterility.

RESUMO

Introduction: This study aimed to identify what indigenous university students in Brazil perceived to be important and feasible actions to protect the survival of indigenous peoples from climate change-related impacts. Methods: Concept mapping, which is a participatory mixed methodology, was conducted virtually with 20 indigenous students at two universities in Brazil. A focus prompt was developed from consultations with indigenous stakeholders and read "To protect the survival of the Indigenous Peoples from climate change, it is necessary to…". Students brainstormed 46 statements, which they then sorted into clusters based on conceptual similarity. They rated each statement for importance and feasibility. Quantitative multivariate analyses of clusters and ratings were conducted to produce multiple visual maps of perceived actionable priorities. These analyses used the Group Wisdom TM software. Results: Students agreed on 8 clusters that reflect the factors that influence the survival of indigenous peoples-preservation of lands 0.16 (SD 0.13), protection of demarcated lands 0.31 (SD 0.10), indigenous health and wellbeing 0.35 (SD 0.14), ancestral customs 0.46 (SD 0.04), global and national actions 0.61 (SD 0.13), indigenous rights 0.64 (SD 0.23), collective living 0.71 (SD 0.21), and respect 0.75 (SD 0.14). Discussion: The most actionable priorities are related to the respect for their lands and customs, educational initiatives in schools about the importance of indigenous peoples to society, guarantees for basic health rights, and culturally appropriate provision of care, with specific mention of mental healthcare. The findings aligned closely with the concept of indigenous self-determination, which is rooted in autonomy and respect for cultural diversity, and the right to make decisions that impact their lives, land, and resources.

RESUMO

Background: The alarming increase in annual deforestation rates has had devastating consequences in climate change, and it is affecting Indigenous people, who depend entirely on the land for survival and has also weakened the rainforest's crucial role in stabilizing the global climate. Recognizing and respecting Indigenous people's needs and social, economic, and historical conditions influence health and healthcare. This study aimed to conduct online concept mapping workshops with university students to identify perceived important and feasible actions for improving the mental health of Indigenous people living in their territory in association with climate change. Methods: Concept mapping, a participatory mixed methodology, was conducted virtually with 20 Indigenous students at two universities in Brazil. A focus prompt was developed from consultations with Indigenous stakeholders and read-"To improve the mental health of Indigenous peoples in their territory during climate change crises, it is necessary to…." Results: University students organized 42 unique statements in 6 clusters that cover a wide range of topics: family support, 0.68 (SD 0.19); respect and understanding, 0.37 (SD 0.08); improvement actions, 0.52 (SD 0.07); public policies in favor of Indigenous people's mental health, 0.24 (0.09); health actions, 0.15 (SD 0.08); Indigenous training in health and its importance in improving mental health 0.32 (SD 0.07). Conclusion: These clusters range from community initiatives, public policies, health actions, and strengthening professional services in Indigenous communities. These all provide numerous concrete ideas for developing interventions designed to address mental health challenges associated with climate change.

RESUMO

This systematic review and meta-analysis assessed the effects of SARS-Cov-2 and mRNA vaccines on male reproduction. We conducted a comprehensive search using terms such as "COVID-19," "vaccine," and "sperm parameters" on various electronic databases, including MEDLINE (PubMed), BVS (LILACS and others), Embase (Elsevier), and Cochrane Library. We included observational studies, including cohort, case-control, and cross-sectional studies. Of the 2054 records initially identified, we carefully examined 47 full-text articles and excluded 26 articles for specific reasons, ultimately including 21 studies for our analysis. Among these, 16 studies focused on assessing seminal parameters in patients with COVID-19, while five studies investigated the effects of COVID vaccines on seminal parameters. A meta-analysis of seminal parameters in men before and after the COVID-19 pandemic revealed significant differences in seminal concentration, progressive motility, total motility, and normal morphology. These findings indicate a positive impact of the analyzed parameters before the onset of COVID-19. However, the quality of the evidence was considered low. In contrast, a meta-analysis of five studies evaluating seminal parameters before and after the SARS-Cov-2 vaccine did not show any significant differences in total motility. This analysis, involving 256 men from four studies, provided low-quality evidence, suggesting that mRNA vaccines do not affect male reproduction. Overall, our findings suggest that seminal parameters exhibit considerable variability depending on specific outcomes and the study design. However, based on available evidence, it appears that mRNA vaccines do not have detrimental effects on male reproductive function.

RESUMO

Background: Anal cancer prevention has two critical points: the incidence rate is several fold higher for some groups, such as people living with human immunodeficiency virus (HIV) and men who have sex with men (MSM), and there is not a well-defined guideline for its screening. This systematic review evaluates the accuracy of DNA HRHPV (high-risk human papillomavirus), mRNA HPV, DNA HPV16 isolated and p16 staining biomarkers in anal canal smears for identifying anal intraepithelial neoplasia (AIN) 2 or 3, summarised as anal high-grade squamous intraepithelial lesions (aHSIL), and cancer. Methods: We searched the MEDLINE, Cochrane Library and Embase electronic databases as well as Grey literature to identify eligible papers published up to 31st July 2022. This systematic review and meta-analysis included observational studies comparing biomarker tests to histopathology after HRA (High-resolution Anoscopy) as a reference standard. We (ACM, TF) analysed studies in which patients of both sexes were screened for anal cancer using DNA HRHPV, mRNA HPV, DNA HPV16 and/or p16 biomarkers. The analysis was performed in pairs, for instance AIN2 or worse (AIN2+) vs. AIN1, HPV infection and normal (AIN1-). PROSPERO CRD42015024201. Findings: We included 21 studies with 7445 patients. DNA HR HPV showed a higher sensitivity 92.4% (95% CI 84.2-96.5), specificity 41.7% (95% CI 33.9-44.9) and AUC 0.67, followed by the mRNA HPV test, with a sensitivity 77.3% (95% CI 73.2%-80.9%), specificity 61.9% (95% CI 56.6-66.9) and AUC 0.78. DNA HPV16 showed higher specificity 71.7% (95% CI 55.3-83.8), followed by p16 test, 64.1% (95% CI 51.0-75.4); Sensitivity of DNA HPV16 was 53.3% (95% CI 35.4-70.3) and AUC 0.69, while p16 had a sensitivity of 68.8% (95% CI 47.9-84.1) and AUC 0.74. Subgroup analysis of MSM with HIV, with 13 studies and 5123 patients, showed similar accuracy, with a bit higher sensitivities and lower specificities. Considering the measure of the total between-study variability, mRNA HPV tests showed the smallest area of the 95% prediction ellipse, 6.0%, influenced by the low logit sensitivity, 0.011. All other groups of tests exceed 50% prediction ellipse area, which represent a high heterogeneity. Interpretation: Our findings suggested that DNA HR HPV can be a useful tool for screening for aHSIL and anal cancer if followed by biomarker with a higher specificity. As an isolated test, mRNA HPV had better performance. Funding: There was no funding source for this study.

RESUMO

This systematic review and meta-analysis aim to evaluate whether treatment with metformin would reduce Anti-Müllerian Hormone levels in patients with polycystic ovary syndrome. A search was performed in Medline, Embase, Web of Science, and Cochrane Library databases and grey literature (Google Scholar). The following keywords were used in the search strategy: "Polycystic Ovary Syndrome", "Anti-Mullerian Hormone", "Metformin". The search was limited to human studies, with no language restriction. 328 studies were found, 45 studies were selected for full-text reading and 16 of those studies, six randomized controlled trial and 10 non-randomized studies were included. The synthesis of randomized controlled trials, metformin showed a reduction in serum levels of Anti-Müllerian Hormone compared to control groups (SMD - 0.53, 95 %CI - 0.84 to - 0.22, p < 0.001, I2 = 0 %, four studies, 171 participants, high quality of evidence). Six non-randomized studies evaluated data before and after the metformin intervention. The synthesis showed that using metformin reduced serum Anti-Müllerian Hormone values (SMD - 0.79, 95 %CI - 1.03 to - 0.56, p < 0.001, I2 = 0 %, six studies, 299 participants, low quality of evidence). Metformin administration in women with polycystic ovary syndrome is associated significantly with reduced Anti-Müllerian Hormone serum levels.

RESUMO

BACKGROUND: This study was carried out to assess the effects of omega-3 supplementation as an adjunct treatment for eating and psychological symptoms in patients with anorexia nervosa. METHODS: We conducted a systematic review of the literature using the terms 'anorexia nervosa' AND 'Fatty Acids, Omega-3'. Five randomised controlled trials with a total of 144 participants, published between 2003 and 2022, were included. RESULTS: The effects of supplementation of omega-3 on anxiety were standardised mean difference (SMD) 0.79, 95% confidence interval (CI) -0.08 to 1.66; p = 0.08; I² = 3%; two studies, 33 participants; moderate quality of evidence. For depression, the supplementation of omega-3 was SMD: 0.22, 95% CI: -0.50 to 0.93; p = 0.18; I² = 45%; two studies, 33 participants; moderate quality of evidence. For obsessive-compulsive disorder, the supplementation of omega-3 was SMD: -0.22, 95% CI: -0.70 to 2.25; p = 0.36; I² = 0%; three studies, 32 participants; low quality of evidence. CONCLUSION: This research showed that regardless of dose, time or, if associated with other components, the use of omega-3 supplementations as an adjuvant treatment showed no evidence of effect in eating and psychological symptoms in patients with anorexia nervosa.

RESUMO

Background: The increase in life expectancy and in the number of individuals over 60 years old brings new demands to health professionals and services based on the physiological changes that occur in this population. The aging process results in changes in body composition, increasing body fat and reducing muscle mass, in addition to a reduction in bone mass. Aim: The aim of this study was to examine the effect of whey protein and vitamin D supplementation on body composition and skeletal muscle in older adults living in long-term care facilities. Methods: This study is a double-blind randomized controlled trial. Thirty older adults (>60 years old) were randomized and allocated in three groups: group receiving resistance training and supplementation receiving resistance training, whey protein and vitamin D; group received resistance and placebo training receiving resistance training and placebo, and control group without any intervention. Body composition was measured by dual-energy X-ray absorptiometry at baseline, 12 weeks, and 24 weeks. Results: The mean age was 74.87 (± 8.14) years. A significant difference (p = 0.042) was observed between the group receiving resistance training and supplementation and control groups in relation to lean mass increase (kg) at 24 weeks. After 24 weeks of intervention, there was a significant increase in Relative index of muscle mass for the two groups that underwent resistance training, group received resistance and placebo training (p = 0.042) and group receiving resistance training and supplementation (p = 0.045), in relation to the control. Conclusion: Combined supplementation of whey protein and vitamin D with resistance training can significantly improve lean mass, total mass, and relative index of muscle mass in institutionalized older adults.

RESUMO

Background: Endometriosis is a clinical condition associated with genetic, endocrine, and immunological factors, present in 6 to 10% of women of reproductive age. Currently, the human microbiota has been studied and associated with the evolution of diseases due to its influence on pathogenesis, indicating that changes in the colonization of microorganisms in the genitourinary and gastrointestinal systems can promote physiological changes that can trigger inflammatory and immunological processes and hormonal dysregulation, which can be linked to endometriosis. Thus, this systematic review and meta-analysis evaluated microbiota changes in women with endometriosis. Methods: The following electronic databases were searched up to April 2022: Medline, Embase, Web of Science, Cochrane Library, and gray literature (Google Scholar), using the keywords "dysbiosis", "microbiome" and "endometriosis", combined with their synonyms. The observational studies conducted with women diagnosed with endometriosis and women without endometriosis as controls were included. For the analyses, a standard mean difference with a 95% confidence interval was used using RevMan software (version 5.4), and for methodological quality assessment, the Newcastle-Ottawa scale was used. Results: A total of 16 studies were found in the literature assessing the composition of the microbiota in women with endometriosis, and no significant difference were found for changes in alpha diversity analysis in gut microbiota (SMD = -0.28; 95% CI = -0.70 to 0.14; P = 0.19; I2 = 52%; four studies, 357 participants) or vaginal microbiota (SMD = -0.68; 95% CI = -1.72 to 0.35; P = 0.19; I2 = 66%; two studies, 49 participants). Conclusion: In intestinal and vaginal samples from women with endometriosis, alpha-diversity did not present a significant difference when compared to the control population. However, each study individually showed a possible relationship between the female microbiota and endometriosis. This trial is registered with CRD42021260972.

RESUMO

ABSTRACT BACKGROUND: The legacies of colonization and of policies of forced assimilation continue to be a cause of intergenerational trauma, manifested through feelings of marginality, depression, anxiety and confusion, which place indigenous peoples at increased risk of suicide. OBJECTIVES: To assess the quality, content, delivery and effectiveness of interventions for preventing suicides among indigenous adolescents. DESIGN AND SETTING: Systematic review conducted with Cochrane methodology, Campo Grande, Mato Grosso do Sul, Brazil. METHODS: The Cochrane library, MEDLINE, EMBASE, CINAHL, LILACS and PsycINFO databases were searched for studies published up to February 2021. The following inclusion criteria were used: published in any language; interventions that aimed to prevent suicides among indigenous adolescents; randomized or non-randomized study with a control or comparative group; and validated measurements of mental health problems. RESULTS: Two studies were identified: one on adolescents in the remote Yup'ik community in south-western Alaska, and the other on Zuni adolescents in New Mexico. Both studies showed evidence of effectiveness in interventions for reducing some of the risk factors and increasing some of the protective factors associated with suicide. High levels of community engagement and culture-centeredness were key anchors of both studies, which ensured that the intervention content, delivery and outcome measurements aligned with the beliefs and practices of the communities. Both studies were judged to have a moderate risk of bias, with biases in sample selection, attrition and inadequate reporting of results. CONCLUSIONS: The current evidence base is small but signaled the value of culturally appropriate interventions for prevention of suicide among indigenous adolescents. REGISTRATION DETAILS: The study protocol is registered in the international prospective register of systematic reviews (PROSPERO); no. CRD42019141754.

RESUMO

Abstract Objectives: to assess the effects of vitamin D supplementation during pregnancy on the outcomes of vitamin D concentration in newborns, length at birth, overall health (Apgar), birth weight and maternal vitamin D concentration after childbirth. Methods: this research was conducted in the electronic databases of MEDLINE, LILACS, EMBASE and Cochrane Library until December 2020, using the terms "vitamin D", "pregnancy", "vitamin D deficiency", "infant", "newborn" and their synonyms. Randomized controlled trials were searched by evaluating the effects of maternal vitamin D supplementation in neonates. The data was analyzed on RevMan 5.4 software and the quality of evidence on GRADE. Results: the newborn's overall health condition was presented as Apgar, with a mean difference (MD) of 0.15 (CI95%=0.06-0.25; p=0.002; I2=0%, two studies, 648 participants, moderate quality evidence) at the first minute and 0.11 (CI95%=0.04-0.17; p=0.001; I2=0%, two studies, 648 participants, moderate quality evidence) at the fifth minute. Significant effects were also presented at the length at birth considering any supplemented dose (MD=0.19; CI95%=0.08-0.30; p=0.0010; I2=0%, 1452 participants, low quality evidence) and birth weight in doses higher than 4000IU/day (MD=257.05 (CI95%=137.81-376.29; p<0.0001; I2=14%, 176 participants, moderate quality evidence). Conclusion: vitamin D supplementation during pregnancy improves serum 25 (OH) D concentration and suggests positive effects on overall health condition, length at birth and birth weight. PROSPERO CRD42017073292.

Efeitos significativos também foram apresentados para o comprimento ao nascer em qualquer dose suplementada (DM=0,19 (IC95%=0,08-0,30; p=0,0010; I2=0%, 1452 participantes, evidência de baixa qualidade) e peso ao nascer em doses maiores que 4000UI/dia (DM=257,05 (IC95%=137,81-376,29; p<0,0001; I2=14%, 176 participantes, evidência de qualidade moderada). Conclusão: a suplementação de vitamina D durante a gravidez melhora a concentração sérica de 25 (OH)D e sugere apresentar efeitos positivos no estado geral de saúde, comprimento ao nascer e peso ao nascer. PROSPERO CRD42017073292.

RESUMO

BACKGROUND: The legacies of colonization and of policies of forced assimilation continue to be a cause of intergenerational trauma, manifested through feelings of marginality, depression, anxiety and confusion, which place indigenous peoples at increased risk of suicide. OBJECTIVES: To assess the quality, content, delivery and effectiveness of interventions for preventing suicides among indigenous adolescents. DESIGN AND SETTING: Systematic review conducted with Cochrane methodology, Campo Grande, Mato Grosso do Sul, Brazil. METHODS: The Cochrane library, MEDLINE, EMBASE, CINAHL, LILACS and PsycINFO databases were searched for studies published up to February 2021. The following inclusion criteria were used: published in any language; interventions that aimed to prevent suicides among indigenous adolescents; randomized or non-randomized study with a control or comparative group; and validated measurements of mental health problems. RESULTS: Two studies were identified: one on adolescents in the remote Yup'ik community in south-western Alaska, and the other on Zuni adolescents in New Mexico. Both studies showed evidence of effectiveness in interventions for reducing some of the risk factors and increasing some of the protective factors associated with suicide. High levels of community engagement and culture-centeredness were key anchors of both studies, which ensured that the intervention content, delivery and outcome measurements aligned with the beliefs and practices of the communities. Both studies were judged to have a moderate risk of bias, with biases in sample selection, attrition and inadequate reporting of results. CONCLUSIONS: The current evidence base is small but signaled the value of culturally appropriate interventions for prevention of suicide among indigenous adolescents. REGISTRATION DETAILS: The study protocol is registered in the international prospective register of systematic reviews (PROSPERO); no. CRD42019141754.
