RESUMO

INTRODUCTION: Understanding suicide in more isolated territories is a challenge because of the entanglement of cultural identity with historical, geographical and sociocultural specificities. This knowledge is a necessary precondition for the implementation of targeted prevention strategies in regions such as the French overseas territories (FOT), where data concerning suicidal risk factors is still incomplete. We aim to untangle sociocultural and clinical suicide risk factors by integrating a novel anthropological and psycholinguistic approach into the psychological autopsy method. This article describes the protocol of the clinical study 'Contribution of Psychological Autopsy to the Understanding of Suicidal Behaviours in Overseas France' (AUTOPSOM study), designed to identify common or new specific suicide risk factors in four FOT. METHODS AND ANALYSIS: A multicentre epidemiological study will be carried out in four FOTs (French Polynesia, Martinique, La Reunion and French Guiana) and at a comparison site in mainland France (La Somme). The methodology will be based on a mixed-methods (quantitative and qualitative) approach using a psychological autopsy to collect clinical data and life events in the deceased's life. We implemented an exploratory multimethod strategy that combines a succession of epidemiological, anthropological, psycholinguistic and psychological methods with a semiautomated analysis of the discourse of relatives bereaved by suicide. ETHICS AND DISSEMINATION: The study protocol (first version) was approved by the French Ethics Committee (CPP OUEST II, approval #22.04267.000122) and the Ethics Committee of French Polynesia (JOPF of 5 April 2022; CEPF opinion n°91 of 29 March 2022). The overall results and the perspectives established at the end of the study will be communicated to the bereaved relatives according to their will and serve for local suicide prevention purposes. TRIAL REGISTRATION NUMBER: NCT05773898.

RESUMO

OBJECTIVES: Research trends concerning hearing loss within teen rural populations are limited and current evidence suggests that extended high-frequency audiometry can be a sensitive tool to detect subclinical hearing loss. Moreover, current research emphasises the importance of representing different ethnic populations in science. This study aimed to determine the prevalence of acquired hearing loss through conventional pure-tone (0.25-8 kHz) and extended high frequency (EHF) (9-20 kHz) audiometry in Afro-Colombian adolescents from a rural area in Colombia. DESIGN: Observational, cross-sectional study. PARTICIPANTS: 230 Afro-Colombian adolescents aged 13-17 years who attended high school in a rural population from Cartagena, Colombia. INTERVENTIONS: Otoscopic examination, conventional (0.25-8 kHz) and EHF (9-20 kHz) audiometry tests were performed during February-March 2021. Sociodemographic and associated factor questionnaires were also applied to assess probable factors associated with EHF hearing loss. MAIN OUTCOME MEASURES: Prevalence of acquired hearing loss using conventional and EHF audiometry, and factors associated with hearing loss. RESULTS: Of 230 adolescents who met the eligibility criteria, 133 (57.82%) were female. The mean age was 15.22 years (SD: 1.62). The prevalence of hearing loss in at least one ear assessed with conventional audiometry was 21.30% and with EHF audiometry 14.78%. The main abnormal otoscopic findings included: neotympanum (1.30%), myringosclerosis (0.87%) and monomeric scars (0.43%). Factors associated with a higher probability of EHF hearing loss found through logistic regression were older age (prevalence ratio (PR): 1.45; 95% CI 1.16 to 1.80), attending the 'Picó' four or more times a month (PR: 6.63; 95% CI 2.16 to 20.30), attending bars more than three times a month (PR: 1.14; 95% CI 1.03 to 1.59) and self-reported hearing difficulties (PR: 1.24; 95% CI 1.22 to 4.05). CONCLUSIONS: Our results suggest that acquired hearing loss is already widespread among this young rural population.

RESUMO

BACKGROUND: Limited evidence exists on the population attributable fraction (PAF) of cancer cases and deaths in Latin America. In Peru several studies have been published regarding the PAF of various risk factors and their associated diseases. The objective of this study was to estimate the fraction of cancer cases and deaths attributable to potentially modifiable risk factors in Peru in 2018, before the COVID-19 pandemic in the population of 15 years old and older. METHODS: An ecological study was conducted using the prevalence of exposure of the Peruvian population to modifiable risk factors for cancer, the relative risk associated with each factor, and the number of cancer cases and deaths in 2018 as inputs. We used the Parkin formula with a Montecarlo statistical simulation model to calculate the PAF and confidence intervals. The number of new cancer cases and deaths attributed to each risk factor was determined by multiplying the number of cases and deaths in each gender by the PAF of each risk factor. FINDINGS: In Peru, 38.5% of new cases (34.5% in men and 42% in women) and 43.4% of cancer-related deaths (43.4% in men and 43.4% in women) were attributable to modifiable risk factors. The number of cancers attributable was 25,308 (10,439 in men and 14,869 in women) and the number of deaths attributable to cancer was 14,839 (6,953 in men and 7,886 in women). The predominant modifiable risk factors contributing to the highest number of cases and deaths were HPV infection (4,563 cases, 2,409 deaths), current tobacco use (3,348 cases, 2,180 deaths), and helicobacter pylori infection (2,677 cases, 1,873 deaths). Among the risk factors, oncogenic infections constituted the group with the highest PAF (16.6% for cases, 19.2% for deaths) followed by other unhealthy lifestyle factors (14.2% for cases, 16.7% for deaths), tobacco (7.2% for cases, 7.2% for deaths) and ultraviolet radiation (0.5% for cases, 0.3% for deaths). CONCLUSIONS: Prior to the COVID-19 pandemic, 38.5% of cancer cases and 43.4% of cancer-related deaths in Peru were linked to modifiable risk factors in the population of 15 years old and older. Most preventable cancer cases and deaths were related to oncogenic infections, primarily caused by HPV and helicobacter pylori, followed by tobacco and obesity.

RESUMO

Traumatic muscle injuries (TMIs) and muscle pain (MP) negatively impact athletes' performance and quality of life. Both conditions have a complex pathophysiology involving the interplay between genetic and environmental factors. Yet, the existing data are scarce and controversial. To provide more insights, this study aimed to investigate the association of single-nucleotide polymorphisms (SNPs) previously linked to athletic status with TMI and MP after exercise among Brazilian high-performance athletes from different sports modalities (N = 345). The impact of important environmental determinants was also assessed. From the six evaluated SNPs (ACTN3 rs1815739, FAAH rs324420, PPARGC1A rs8192678, ADRB2 rs1042713, NOS3 rs1799983, and VDR rs731236), none was significantly associated with TMI. Regarding MP after exercise, ACTN3 rs1815739 (CC/CT vs. TT; adjusted odds ratio (aOR) = 1.90; 95% confidence interval (95%Cl), 1.01-3.57) and FAAH rs324420 (AA vs. AC/CC; aOR = 2.30; 95%Cl, 1.08-4.91) were independent predictors according to multivariate binomial analyses adjusted for age (≥23 vs. <23 years), sex (male vs. female), and tobacco consumption (yes vs. no). External validation is warranted to assess the predictive value of ACTN3 rs1815739 and FAAH rs324420. This could have implications for prophylactic interventions to improve athletes' quality of life.

RESUMO

INTRODUCTION: Living guidelines provide reliable, ongoing evidence surveillance and regularly updated recommendations for healthcare decision-making. As a relatively new concept, most of the initial application of living approaches has been undertaken in high-income countries. However, in this scoping review, we looked at what is currently known about how living guidelines were developed, used and applied in low-income and middle-income countries. METHODS: Searches for published literature were conducted in Medline, Global Health, Cochrane Library and Embase. Grey literature was identified using Google Scholar and the WHO website. In addition, the reference lists of included studies were checked for missing studies. Studies were included if they described or reflected on the development, application or utility of living guideline approaches for low-income and middle-income countries. RESULTS: After a full-text review, 21 studies were included in the review, reporting on the development and application of living recommendations in low-income and middle-income countries. Most studies reported living guideline activities conducted by the WHO (15, 71.4%), followed by China (4, 19%), Chile (1, 4.8%) and Lebanon (1, 4.8%). All studies based on WHO reports relate to living COVID-19 management guidelines. CONCLUSIONS: Most of the studies in this review were WHO-reported studies focusing solely on COVID-19 disease treatment living guidelines. However, there was no clear explanation of how living guidelines were used nor information on the prospects for and obstacles to the implementation of living guidelines in low-income and middle-income countries.

RESUMO

Introducción: la diabetes mellitus tipo 2 (DM2) se define como un trastorno metabólico caracterizado por niveles de glucosa en sangre crónicamente elevados. La DM2 representa el paradigma de las enfermedades crónicas en las que existe una estrecha asociación entre factores familiares y ambientales. Por este motivo, este estudio tiene como finalidad determinar la asociación del riesgo a desarrollar DM2 y los hábitos tóxicos no ilícitos en pacientes que residen en una comunidad rural de Peravia, República Dominicana. Tales incluyen: alcohol, café y té. Metodología: Estudio observacional, transversal, analítico y prospectivo. Se aplicó cuestionario, recolectaron datos antropométricos y se determinó glucosa capilar a la muestra (n=304). Resultados: la prevalencia a presentar un alto riesgo a desarrollar DM2 en la población es de 35.5%, mientras que la prevalencia a presentar riesgo bajo es de 64.5%. En cuanto a hábitos tóxicos, no existió correlación positiva entre consumo de té y desarrollo de DM2. Sin embargo, sí entre el consumo de café y alcohol. Conclusiones: los habitantes de salinas presentan un bajo riesgo a desarrollar DM2, pero utilizan factores de riesgos modificables que aumentan la prevalencia a DM2.

Introduction: Type 2 diabetes mellitus (DM2) is defined as a metabolic disorder characterized by chronically elevated blood glucose levels. DM2 represents the paradigm of chronic diseases in which there is a close association between family and environmental factors. Therefore, the purpose of this study is to determine the association of the risk of developing DM2 and non-illicit toxic habits in patients residing in a rural community in Peravia, Dominican Republic. Such habits include alcohol, coffee and tea. Methodology: Observational, cross-sectional, analytical and prospective study. A questionnaire was applied, anthropometric data was collected, and capillary glucose was determined in the study sample (n=304). Results: the prevalence of presenting a high risk of developing DM2 in the population is 35.5%, while the prevalence of presenting low risk is 64.5%. Regarding toxic habits, there was no positive correlation between tea consumption and the development of DM2. However, this result differed between consumption of coffee and alcohol. Conclusions: the inhabitants of Salinas have a low risk of developing DM2 but are subject to modifiable risk factors that increase said prevalence.

RESUMO

RESUMEN El desarrollo de la salud pública en América Latina durante el siglo XX combinó, desde el principio, el marco de la medicina social sobre los orígenes sociales, políticos y ambientales de la enfermedad con los aportes del trabajo de campo de la antropología médica. A pesar de la hegemonía del modelo médico, el surgimiento del marco de la medicina preventiva legitimó aún más la participación de los científicos sociales en el estudio de la multicausalidad de la enfermedad. Sin embargo, las limitaciones que trajo consigo la falta de contextualización histórica y política del modelo de la medicina preventiva dieron paso al movimiento latinoamericano de medicina social, basado en el materialismo histórico, y al desarrollo tanto de la epidemiología crítica como de la antropología médica crítica.

ABSTRACT The development of public health in Latin America during the 20th century combined, early on, the social medicine framework on the social, political, and environmental origins of disease with the contributions of medical anthropological fieldwork. Despite the hegemony of the medical model, the surge of the preventive medicine framework further legitimized the involvement of social scientists in the study of the multicausality of disease. However, the limitations brought by the preventive medicine model's lack of historical and political contextualization gave way to the Latin American social medicine movement, which was grounded in historical materialism, and the development of both critical epidemiology and critical medical anthropology.

RESUMO Desde o início, a evolução da saúde pública na América Latina ao longo do século XX combinou o marco teórico da medicina social sobre as origens sociais, políticas e ambientais das doenças com as contribuições derivadas do trabalho de campo da antropologia médica. Apesar da hegemonia do modelo médico, o surgimento do modelo de medicina preventiva legitimou ainda mais a participação dos cientistas sociais no estudo da multicausalidade das doenças. Entretanto, as limitações causadas pela falta de contextualização histórica e política do modelo de medicina preventiva abriram espaço para o movimento latino-americano de medicina social, fundamentado no materialismo histórico, e para o desenvolvimento da epidemiologia crítica e da antropologia médica crítica.

RESUMO

ABSTRACT Background: A staggering 99% of infant undernutrition mortality comes from Sub-Saharan Africa and South Asia. Despite multiple interventions focusing on nutrition adequacy, 2.7 million children worldwide remain associated with undernutrition-related mortality. The lack of impact from multiple interventions toward undernutrition reflects a strong reason to believe that EED is the missing link that sustains undernutrition in low-to-middle-income countries (LMICs). EED is a sub-clinical condition caused by repeated oral enteropathogenic and non-pathogenic fecal microbes exposure that causes intestinal villous malformation, multi-omics changes, chronic intestinal and systemic inflammation, and gut dysbiosis. EED impacts the absorptive capacity and the integrity of the gut, causing a cycle of undernutrition in children. There is currently no protocol for the diagnosis and treatment of EED, hence EED is widely believed to be highly prevalent and underdiagnosed in LMICs. Objective: To our knowledge, this is the first systematic review to study the impact of nutritional interventions on EED. Previous studies yielded inconsistent results, hence the synthesis of this information is essential in attaining a deeper understanding of EED to formulate new targets of intervention against child undernutrition. Methods: This systematic review is registered to PROSPERO (CRD42022363157) in accordance to PRISMA, using keywords referring to nutrient supplementation, EED, and child growth failure. Results: Eleven articles were eligible for review, comprising randomized controlled trials performed mainly in the African continent, with a total of 5689 healthy children eligible for analysis. Conclusion: The systematic review illustrates that nutritional interventions have a minimal impact on EED biomarkers and linear growth and reflects the importance of understanding better the mechanisms causing EED and its consequences. It appears that the anabolic contribution of nutrition intervention to child growth is negated by EED.

RESUMO Contexto: Um número impressionante de 99% da mortalidade por desnutrição infantil provém da África Subsaariana e do Sul da Ásia. Apesar de múltiplas intervenções focadas na adequação nutricional, 2,7 milhões de crianças em todo o mundo permanecem associadas à mortalidade relacionada à desnutrição. A falta de impacto de múltiplas intervenções em direção à desnutrição reflete uma forte razão para acreditar que a disfunção entérica ambiental (DEA) é o elo perdido que sustenta a desnutrição em países de baixa e média renda. A DEA é uma condição subclínica causada pela exposição repetida a micróbios fecais enteropatogênicos e não patogênicos por via oral, que causa malformação vilosa intestinal, alterações multiômicas, inflamação intestinal e sistêmica crônica, e disbiose intestinal. A DEA impacta a capacidade absortiva e a integridade do intestino, causando um ciclo de desnutrição em crianças. Atualmente, não existe protocolo para o diagnóstico e tratamento da DEA, portanto, acredita-se amplamente que a DEA seja altamente prevalente e subdiagnosticada em países de baixa e média renda. Objetivo: Até onde sabemos, esta é a primeira revisão sistemática para estudar o impacto das intervenções nutricionais na DEA. Estudos anteriores apresentaram resultados inconsistentes, portanto, a síntese dessas informações é essencial para obter uma compreensão mais profunda da DEA e formular novos alvos de intervenção contra a desnutrição infantil. Métodos: Esta revisão sistemática está registrada no PROSPERO (CRD42022363157) de acordo com o PRISMA, utilizando palavras-chave referentes à suplementação de nutrientes, DEA e falha no crescimento infantil. Resultados: Onze artigos foram elegíveis para revisão, compreendendo ensaios clínicos randomizados realizados principalmente no continente africano, com um total de 5689 crianças saudáveis elegíveis para análise. Conclusão: A revisão sistemática ilustra que as intervenções nutricionais têm um impacto mínimo nos biomarcadores da DEA e no crescimento linear, e reflete a importância de entender melhor os mecanismos que causam a DEA e suas consequências. Parece que a contribuição anabólica da intervenção nutricional para o crescimento infantil é negada pela DEA.

RESUMO

OBJECTIVE: The importance of a healthy lifestyle in preventing morbidity and mortality is well-established. The COVID-19 pandemic brought about significant lifestyle changes globally, but the extent of these changes in the Brazilian population remains unclear. The objective of this study was to evaluate changes in lifestyle among the Brazilian general population during the first year of the pandemic. DESIGN: Three consecutive anonymous web surveys were carried out: survey 1 (S1)-April 2020, S2-August 2020 and S3-January 2021. SETTING: Brazil. PARTICIPANTS: The study included 19 257 (S1), 1590 (S2) and 859 (S3) participants from the general population, who were ≥18 years, of both sexes, with access to the internet, self-reporting living in Brazil and who agreed to participate after reading the informed consent. PRIMARY OUTCOME: Lifestyle changes were assessed using the Short Multidimensional Instrument for Lifestyle Evaluation-Confinement (SMILE-C). The SMILE-C assesses lifestyle across multiple domains including diet, substance use, physical activity, stress management, restorative sleep, social support and environmental exposures. We used a combination of bootstrapping and linear fixed-effect modelling to estimate pairwise mean differences of SMILE-C scores overall and by domain between surveys. RESULTS: In all the surveys, participants were mostly women and with a high education level. Mean SMILE-C scores were 186.4 (S1), 187.4 (S2) and 190.5 (S3), indicating a better lifestyle in S3 as compared with S1. The pairwise mean differences of the overall SMILE-C scores were statistically significant (p<0.001). We also observed a better lifestyle over time in all domains except for diet and social support. CONCLUSIONS: Our findings indicate that individuals from a large middle-income country, such as Brazil, struggled to restore diet and social relationships after 1 year of the pandemic. These findings have implications for monitoring the long-term consequences of the pandemic, as well as future pandemics.

RESUMO

Resumen: La atrofia muscular espinal (AME) se define como un conjunto de trastornos neurodegenerativos hereditarios causantes de una variabilidad fenotípica y genotípica que genera un impacto sobre la calidad de vida, desarrollo psicosocial, emocional y funcional de quien la padece. En Colombia se considera una enfermedad huérfana con relación a su baja prevalencia, cronicidad y alta complejidad. El objetivo de este reporte de caso es describir, caracterizar y correlacionar fenotípica y genotípicamente un paciente con sospecha clínica de enfermedad neurodegenerativa. Se trata de una paciente femenina de 32 años de edad, con cuadro clínico consistente en equinismo, varismo, supinación del retropié, aducción del antepié derecho y limitación en muñecas con posterior debilidad y atrofia muscular predominantemente en miembros inferiores, arreflexia generalizada y signo de Gowers positivo. Ante sospecha de enfermedad neuromuscular progresiva degenerativa se solicitan estudios endocrinos, neuromusculares, cardiovasculares, biopsia de nervio sural y estudio genético. Los resultados arrojan biopsia de nervio sural con pérdida de axones con poca desmielinización, y estudio genómico secuenciación de exoma clínico trío realizado utilizando la tecnología Illumina con identificación de variantes con significado clínico patogénico en el gen NOD2 con cigosidad heterocigota y DYNC2H1 homocigota. Finalmente se realiza red de interacción génica mediante programa GeneMania determinando asociaciones génicas. Conclusión: el diagnóstico de AME representa un desafío debido a su amplia variabilidad fenotípica-genotípica, aunque en la mayoría de los pacientes se deben a variantes en el gen SMN1 existen otros genes no 5q asociados a esta patología, un diagnóstico específico impacta en el tratamiento, pronóstico y morbimortalidad atribuida, estableciendo riesgo de heredabilidad y consejería genética en aras de medicina preventiva, predictiva, personalizada y participativa.

Abstract: Spinal Muscular Atrophy (SMA) is defined as a set of hereditary neurodegenerative disorders that cause phenotypic and genotypic variability, impacting the quality of life, psychosocial, emotional, and functional development of those affected. In Colombia, it is considered a rare disease due to its low prevalence, chronicity, and high complexity. The objective of this case report is to describe, characterize, and correlate phenotypically and genotypically a patient with clinical suspicion of neurodegenerative disease. The patient is a 32-year-old female with a clinical picture of equinus, varus, supination of the hindfoot, adduction of the right forefoot, and limitation in wrists with subsequent weakness and predominantly lower limb muscle atrophy, generalized areflexia, and positive Gowers sign. Given the suspicion of progressive degenerative neuromuscular disease, endocrine, neuromuscular, cardiovascular studies, sural nerve biopsy, and genetic testing are requested. The results show sural nerve biopsy with axonal loss with little demyelination, and genomic study using trio clinical exome sequencing performed using Illumina technology with identification of pathogenic clinically significant variants in the Nod2 gene with heterozygous and DYNC2H1 gene with homozygous status. Finally, a gene interaction network is created using the GeneMania program, determining gene associations. The conclusion of this study was the diagnosis of Sma represents a challenge due to its wide phenotypic-genotypic variability. Although most patients are due to variants in the SmN1 gene, there are other non-5q genes associated with this pathology. A specific diagnosis impacts treatment, prognosis, and attributed morbidity and mortality, establishing heritability risk and genetic counseling for the sake of preventive, predictive, personalized, and participatory medicine.

RESUMO

RESUMEN Objetivo La infección por SARS-CoV-2 ha sido relacionada con hipertensión, obesidad y diabetes para riesgo de hospitalización y muerte. Con respecto a las enfermedades pulmonares obstructivas, la literatura es diversa; hay variación en la frecuencia de estas y por ende en su relación con la COVID-19. La evidencia disponible únicamente detalla a los pacientes hospitalizados, y es escasa la referida a trabajadores de la salud, por lo que el analizar las principales comorbilidades en este grupo resulta de ayuda para la implementación de programas preventivos. El objetivo de este estudio fue describir la prevalencia y la asociación de diversas comorbilidades con la infección por SARS-CoV-2 en trabajadores de la salud. Métodos Estudio transversal analítico, en trabajadores del principal centro de referencia nacional para enfermedades respiratorias de México, que acudieron a atención para descarte de infección por SARS-CoV-2 mediante un programa preventivo; para el tamaño de muestra se usó fórmula para cálculo de proporciones. Se analizaron medidas de resumen y asociación. Resultados La prevalencia de COVID-19 fue de 22,9 %. Las comorbilidades más frecuentes en cuanto a prevalencia fueron: sobrepeso (29,0 %), obesidad (13,2 %), tabaquismo (8,6 %), hipertensión (5,5 %), rinitis alérgica (3,9 %) y asma (2,8 %). El sobrepeso, la obesidad y la vacunación contra SARS-CoV-2 tuvieron razones de momios para prevalencia de 1,78, 1,72 y 0,43, respectivamente. Las personas vacunadas y con comorbilidades tienen menor duración de la enfermedad (p=0,001). Conclusiones La obesidad y el sobrepeso muestran asociación con SARS-CoV-2, la vacunación es un factor protector, sobre todo en aquellos pacientes con comorbilidades.

ABSTRACT Objective The SARS-CoV-2 infection has been linked to hypertension, obesity and diabetes as risks of hospitalization and death. Regarding obstructive pulmonary diseases, the scientific literature is diverse; finding variation in the frequency of these and therefore their relationship with COVID-19. The available evidence only details hospitalized patients, with insufficient information referring to health workers, so analyzing the main comorbidities in this group is helpful for the implementation and improvement of preventive programs. The objective of this study was to describe the prevalence and association of comorbidities with SARS-CoV-2 infection in health care workers. Methods Analytical cross-sectional study, in workers of the main national reference center for respiratory diseases in Mexico, who came to care to rule out SARS-CoV-2 infection through a preventive program; calculation of proportions was performed for the sample size. Summary and association measures were calculated. Results The prevalence of COVID-19 was 22.9 %. The most frequent comorbidities were: overweight obesity, smoking, hypertension, allergic rhinitis and asthma, with prevalences of 29.0 %, 13.2 %, 8.6 %, 5.5 %, 3.9%, 2.8 % respectively. Overweight, obesity and vaccination against SARS-CoV-2 had Prevalence Ratios of 1.78, 1.72 and 0.43 respectively. Conclusions Obesity and overweight show association with SARS-CoV-2; vaccination is a protective factor, especially in people with comorbidities.

RESUMO

O homem transgênero apresenta alta susceptibilidade às neoplasias de colo uterino devido à escassez de exames preventivos. O estudo objetiva levantar informações acerca dos desafios e estratégias para a promoção do rastreio e prevenção do câncer cervical em homens transgênero. Trata-se de uma revisão integrativa, desenvolvida em seis etapas a partir da pergunta norteadora: "Quais os desafios e estratégias atuais para a promoção do rastreio efetivo e prevenção de câncer de colo uterino em homens transgênero?". Utilizaram-se descritores combinados com operador booleano "cervical cancer" AND "transgender persons", e foram incluídos artigos completos de 2018 a 2022. Verificou-se que os desafios enfrentados incluem preconceito, despreparo profissional e susceptibilidade à disforia de gênero. Estudos mostraram benefícios relacionados ao uso de swabs vaginais autocolhidos para reduzir o impacto psicológico do exame Papanicolaou, com vistas a reduzir os desafios enfrentados por essa população, e a necessidade de implementar estratégias que aumentem a adesão aos serviços de saúde.

Transgender men are highly susceptible to cervical cancer due to the lack of preventive screening exams. This study aims to gather information about the challenges and strategies for promoting cervical cancer screening and prevention in transgender men. This is an integrative review, developed in six stages, based on the guiding question: "What are the current challenges and strategies for promoting effective screening and prevention of cervical cancer in transgender men?". Descriptors combined with Boolean operator "cervical cancer" AND "transgender persons" were used and full articles from 2018 to 2022 were included. It was found that the challenges faced include prejudice, professional unpreparedness and susceptibility to gender dysphoria. Studies have shown benefits related to the use of self-collected vaginal swabs to reduce the psychological impact of the Pap smear exam, aiming to reduce the challenges faced by this population and to implement strategies to increase adherence to health services.

RESUMO

INTRODUCTION: As of July 2022, a little over one-third of Guatemalans were fully vaccinated. While COVID-19 vaccination rates are not officially reported nationally by racial/ethnic groups, non-governmental organisations and reporters have observed that COVID-19 vaccination rates are especially low among high-risk Indigenous populations. We conducted one of the first studies on COVID-19 vaccine acceptance in Indigenous populations in the Central Highlands of Guatemala, which aimed to better understand the barriers to COVID-19 vaccine uptake and how to improve vaccine promotional campaigns. METHODS: In November 2021, we conducted eight focus group discussions (FGDs) with 42 Indigenous men and women and 16 in-depth interviews (IDIs) with community health workers, nurses and physicians in Chimaltenango and Sololá. Using a participatory design approach, our qualitative analysis used constant comparative methods to understand the inductive and deductive themes from the FGD and IDI transcripts. RESULTS: We found three major overarching barriers to vaccination within the sampled population: (1) a lack of available easily understandable, linguistically appropriate and culturally sensitive COVID-19 vaccine information; (2) vaccine access and supply issues that prevented people from being vaccinated efficiently and quickly; and (3) widespread misinformation and disinformation that prey on people's fears of the unknown and mistrust of the medical establishment and government. CONCLUSION: When developing COVID-19 vaccine messages, content should be culturally relevant, appropriate for low-literacy populations and in the languages that people prefer to speak. Promotional materials should be in multiple modalities (print, radio and social media) and also have specific Maya cultural references (dress, food and concepts of disease) to ensure messaging connects with intended targets. This study supports the need for more robust research into best practices for communicating about COVID-19 vaccines to marginalised communities globally and suggests that policy makers should invest in targeted local solutions to increase vaccine uptake.

RESUMO

PURPOSE: This study aimed to understand 10- to 19-year-old adolescents' conceptions of mental health and well-being, and suggestions for appropriate interventions, in three low- and middle-income countries to inform the design of adolescent-responsive preventive and promotive mental health programming. METHODS: Ninety-one adolescents participated in focus group discussions in Belize, Kazakhstan, and South Africa. The discussions were recorded, transcribed, translated, and analyzed using thematic analysis. RESULTS: Adolescents were active contributors to the discussions and provided important information and solutions for improving adolescents' mental health from interpersonal skills training to interventions in schools and communities. Adolescents identified a need for social emotional skills development, particularly regarding interpersonal relationships and navigating peer pressure and bullying. Furthermore, the discussions highlighted the need for programming to be tailored to the local context regarding language, contextual challenges faced by adolescents, and choice of program facilitators. Adolescents valued supportive interactions with adults in their lives and recommended that programs should include teacher/parent training on interacting with adolescents. CONCLUSIONS: These findings highlight that adolescents are valuable partners in developing adolescent health interventions and show that social emotional skills are key components in such interventions. These programs should be culturally and locally appropriate and include components for teachers and parents.

RESUMO

ABSTRACT Introduction: Ballroom dancing is a high-intensity sport. Exaggerated training plans and an overtraining range can easily cause sports injuries. Athletes should take the necessary protective measures when training or competing, including exercises with preventative intent. Objective: This research paper thoroughly investigates the current status of ballroom dance injuries in colleges and universities. Methods: This research selects 28 students who majored in ballroom dancing as experimental subjects. The volunteers were divided into a control group and an experimental group. The experimental group received an exercise prescription for 12 weeks of exercise. The control group did not do any exercise for 12 weeks. Injury statistics were performed after a 12-week comparative trial. The effect of exercise prescription on injury reduction in ballroom dancing was discussed.

RESUMO

Abstract We have developed and present in this work a series of algorithms that display a long-duration electrocardiogram (ECG) in a compact form of stacked beats, extracting and visualizing the basic features and facilitating the tedious and time-consuming process of ECG analysis for cardiologists. The expert system based on this representation provides detection of atypical heartbeats, precursors of cardiovascular disease, and their locations in each of the 12 leads. This system was extensively tested with two public databases, MIT-BIH arrhythmia database and China Physiological Signal Challenge (CPSC2018), showing its rapid ECG processing and high efficiency in detecting abnormalities in beat morphology. In particular, tests for atypical beats based on the CPSC2018 database revealed that the set of ECGs marked as normal contains a considerable number of leads with atypical beats. The system is used as a classifier into two classes, normal beats, and atypical beats, the latter being the precursors or indicators of cardiovascular diseases (CVD). It is considered potentially useful for routine studies in groups at high risk of CVD in early stages, as a preventive medicine tool in the public health area. The system allows an intervention of a cardiologist in the intermediate stages of ECG analysis to corroborate the diagnosis in ambiguous cases.

Resumen Desarrollamos y presentamos una serie de algoritmos que muestran un electrocardiograma (ECG) de larga duración en forma compacta de latidos apilados, extrayendo y visualizando características básicas y facilitando el tedioso y lento proceso de análisis de ECG para cardiólogos. El sistema experto basado sobre esta representación provee detección de latidos cardíacos atípicos, precursores de enfermedades cardiovasculares (ECV) y su ubicación en cada uno de las 12 derivadas. Este sistema se probó exhaustivamente con dos bases de datos públicas, base de datos de arritmias del MIT-BIH y China Physiological Signal Challenge (CPSC2018), lo que demostró su rápido procesamiento de ECG y alta eficiencia en la detección de anomalías en la morfología de los latidos. En particular, las pruebas en la base de datos CPSC2018 revelaron que el conjunto de ECG marcados como normales contiene una cantidad considerable de derivadas con latidos atípicos. El sistema se utiliza como clasificador en dos clases, latidos normales y atípicos, siendo estos últimos indicadores de enfermedades cardiovasculares (ECV). Se considera potencialmente útil para estudios de rutina en grupos con alto riesgo de ECV en etapas tempranas, como herramienta de medicina preventiva en el área de salud pública. El sistema permite la intervención del cardiólogo en etapas intermedias del análisis del ECG para corroborar el diagnóstico en casos ambiguos.
