Reemergencia de la encefalitis equina del oeste (WEEV) en la Argentina: una revisión de aspectos epidemiológicos, virológicos y clínicos de relevancia / Reemergence of western equine encephalitis in Argentina

La encefalitis equina del oeste (WEEV, por su sigla en inglés, Western Equine Encephalitis) es una enfermedad reemergente en Argentina a partir del año 2023. La co-municación inicial fue en 1933, las últimas epizootias ocurrieron en 1983 y el último caso humano se registró en 1996. Se revisan las características del agente causal, la ecología con especial referencia a los vectores iden-tificados en el país, su competencia en la transmisión y el ciclo así como los factores de riesgo para adquirir la enfermedad. La situación epidemiológica en equinos y humanos desde noviembre 2023 hasta marzo 2024 es analizada. Se describen las formas clínicas de presen-tación de la enfermedad humana, las posibilidades evo-lutivas, los datos disponibles en los casos confirmados y el tratamiento. La metodología y algoritmo empleados para el diagnóstico etiológico en el Centro Nacional de Referencia son detallados. Las estrategias para la pre-vención y el control se basan en la vacunación de los equinos, el saneamiento ambiental y el control del foco ante la presentación de la enfermedad animal (vigilancia epidemiológica activa)

Western equine encephalitis (WEE) is a re-emerging dis-ease in Argentina starting in 2023. Since the initial notifi-cation in 1933, the last epizootics occurred in 1983, and the last human case was recorded in 1996.The charac-teristics of the causative agent, the ecology with special reference to vectors identified in the country, their compe-tence in transmission, and the cycle as well as the risks factors for acquiring the disease, are reviewed.The epidemiological situation in horses and humans from November 2023 to March 2024 is analyzed. The clinical presentation of the human disease, its evolutionary po-tential, available data in confirmed cases, and the treat-ment are described.The methodology and algorithm used for the etiological diagnosis at the National Reference Center are detailed. Strategies for prevention and control are based on vaccination of horses, environmental sani-tation and outbreak control in the presence of the animal disease (active epidemiological surveillance)

Maintaining the Region of the Americas free of polio: best practices for incident management support teams.

The Pan American Health Organization (PAHO) and its Member States have been leading the efforts to eradicate wild poliovirus in the Region of Americas since smallpox's successful elimination in 1971. The region became the first to be certified free of wild poliovirus in 1994. However, in July 2022, an unvaccinated patient with no recent travel history was diagnosed with poliomyelitis in the United States of America. In response to the emergence of a circulating vaccine-derived poliovirus in the United States, PAHO established the Polio Incident Management Support Team. This team has been coordinating response efforts, focusing on: coordination, planning, and monitoring; risk communication and community engagement; surveillance and case investigation; vaccination; and rapid response. In this paper, we identified and documented best practices observed following establishment of the Incident Management Support Team (September 2022-2023) through a comprehensive review and analysis of various data sources and country-specific data from the polio surveillance dashboard. The aim was to share these best practices, highlighting technical support and implementation of polio measures by Member States. Despite several challenges, the Americas region remains polio-free. Polio risk is declining, with a July 2023 assessment showing fewer countries at medium, high, and very high risk. This progress reflects improved immunization coverage, surveillance, containment, health determinants, and outbreak preparedness and response. The PAHO Polio Incident Management Support Team has played a key role in supporting these efforts.

En este artículo, se determinan y documentan las mejores prácticas observadas después de la creación del equipo de apoyo a la gestión de incidentes (septiembre del 2022-2023) mediante una revisión y un análisis pormenorizados de datos procedentes de diversas fuentes y de datos específicos de los países del panel de vigilancia de la poliomielitis. El objetivo fue poner en común estas mejores prácticas y resaltar el apoyo técnico y la aplicación de medidas contra la poliomielitis por parte de los Estados Miembros. A pesar de los diversos desafíos, la Región de las Américas se mantiene libre de poliomielitis. El riesgo de esta enfermedad es cada vez menor, y la evaluación de julio del 2023 muestra una disminución del número de países con un riesgo medio, alto o muy alto. Este progreso refleja la mejora de la cobertura de inmunización, la vigilancia, la contención, los determinantes de la salud y la preparación y respuesta ante brotes. El equipo de apoyo a la gestión de incidentes relacionados con la poliomielitis de la OPS ha desempeñado un papel fundamental para brindar apoyo a estas iniciativas.

Sex and Gender Differences on the Impact of Metabolism-Disrupting Chemicals on Obesity: A Systematic Review.

Obesity represents an important public health concern, being one of the leading causes of death worldwide. It is a multifactorial disease with many underlying intertwined causes, including genetic, environmental and behavioral factors. Notably, metabolism-disrupting chemicals (MDCs) can alter the set point control of metabolism, affecting the development and function of the adipose tissue. Epidemiological studies have reported associations between human exposure to MDCs and several altered metabolic endpoints. It is also noteworthy that sex and gender represent important risk factors in the development of obesity. Different sex-related biological and physiological characteristics influence individual susceptibility, whereas gender represents a critical component in determining the different exposure scenarios. Although some advancements in the treatment of obesity have been achieved in preclinical and clinical studies, the obesity pandemic continues to increase worldwide. The present study performed a systematic review of recent studies considering the effects of MDCs on obesity, with a specific focus on sex- and gender-related responses. This review highlighted that MDCs could differently affect men and women at different stages of life even though the number of studies evaluating the association between obesity and MDC exposure in relation to sex and gender is still limited. This evidence should urge researchers to carry out studies considering sex and gender differences. This is essential for developing sex-/gender-tailored prevention strategies to improve public health policies and reduce exposure.

Increasing awareness for dementia risk reduction through a public awareness campaign in Denmark: A pre-post study.

OBJECTIVE: It is estimated that about 40% of all dementia cases are potentially attributable to modifiable risk factors, but awareness of this is relatively lacking. METHODS: An 18-months nation-wide public awareness campaign on dementia risk reduction was rolled out in Denmark that combined a mass-media approach with an online risk assessment tool and knowledge bank targeting all inhabitants aged between 40 and 75 years. Campaign effects (increase in awareness and knowledge of modifiable dementia risk and protective factors) were assessed via online surveys in two independent random samples before (n = 1003) and after the campaign (n = 1076). RESULTS: After adjusting for differences in educational level between the two samples, there was no significant difference in awareness of dementia risk reduction between the pre-campaign (66.5% aware) and post-campaign (63.4% aware) sample (probit z = -0.08, p = 0.151). The number of correctly identified risk/protective factors was significantly higher in the post-campaign sample. After adjusting for potential confounding factors, self-reported exposure to the campaign was associated with more awareness, better recognition of risk/protective factors, more motivation for and actual implementation of lifestyle changes. CONCLUSIONS: This mass-media campaign did not increase overall awareness that dementia risk is partly modifiable. However, exposure to the campaign was associated with more awareness and willingness to take action to improve brain health. Future campaigns should tailor messages to specific subgroups to broaden the reach (e.g., males), co-create materials with the target group, and give special attention to the contribution of metabolic/cardiovascular risk factors to dementia risk.

Obsessive-compulsive symptoms, perceived burdensomeness, and thwarted belongingness: Associations and implications among US veterans.

OBJECTIVE: Obsessive-compulsive disorder (OCD) is among the most debilitating psychiatric disorders worldwide, but has gone relatively unnoticed within the US veteran population. Simultaneously, suicide rates continue to remain high within this population despite the high volume of veterans who receive psychiatric care. With recent research demonstrating OCD's unique relationship with suicidality, it is imperative to explore this association and factors that may explain this association within veterans. METHODS: The present study investigated OCD symptoms and their relationship with two known risk factors of suicide, perceived burdensomeness (PB) and thwarted belongingness (TB), in two samples of veterans. RESULTS: In the first study (N = 100), OCD symptoms were found to be uniquely related to both PB and TB even after covarying for demographics, trauma exposure, and probable depression. In the second study (N = 99), these relationships were replicated longitudinally. OCD symptoms at baseline were found to be indirectly related to suicidal ideation severity at a 1-month follow-up via PB and TB at post-treatment. CONCLUSION: This study highlights the importance of assessing and addressing OCD symptoms within veterans due to the unique relationship these symptoms have with suicidal constructs. A deeper understanding of the impact of OCD within the veteran population will inform future prevention and intervention efforts.

Patients' preferences for fracture risk communication: the Risk Communication in Osteoporosis (RICO) study.

The RICO study indicated that most patients would like to receive information regarding their fracture risk but that only a small majority have actually received it. Patients globally preferred a visual presentation of fracture risk and were interested in an online tool showing the risk. PURPOSE: The aim of the Risk Communication in Osteoporosis (RICO) study was to assess patients' preferences regarding fracture risk communication. METHODS: To assess patients' preferences for fracture risk communication, structured interviews with women with osteoporosis or who were at risk for fracture were conducted in 11 sites around the world, namely in Argentina, Belgium, Canada at Hamilton and with participants from the Osteoporosis Canada Canadian Osteoporosis Patient Network (COPN), Japan, Mexico, Spain, the Netherlands, the UK, and the USA in California and Washington state. The interviews used to collect data were designed on the basis of a systematic review and a qualitative pilot study involving 26 participants at risk of fracture. RESULTS: A total of 332 women (mean age 67.5 ± 8.0 years, 48% with a history of fracture) were included in the study. Although the participants considered it important to receive information about their fracture risk (mean importance of 6.2 ± 1.4 on a 7-point Likert scale), only 56% (i.e. 185/332) had already received such information. Globally, participants preferred a visual presentation with a traffic-light type of coloured graph of their FRAX® fracture risk probability, compared to a verbal or written presentation. Almost all participants considered it important to discuss their fracture risk and the consequences of fractures with their healthcare professionals in addition to receiving information in a printed format or access to an online website showing their fracture risk. CONCLUSIONS: There is a significant communication gap between healthcare professionals and patients when discussing osteoporosis fracture risk. The RICO study provides insight into preferred approaches to rectify this communication gap.

Factors Associated with HIV Testing Among Spanish and English-Speaking Latino Adolescents Aged 13-18.

Adolescent Latino men who have sex with men (LMSM) in the U.S. are disproportionately impacted by HIV. However, there has been limited focus on their HIV prevention and risk behaviors. In this study, we examine the rates of HIV testing and explore the significant demographic and healthcare factors that influence HIV prevention among adolescent LMSM. The analysis for this study utilized data collected during the baseline assessment of SMART, a pragmatic trial aimed at evaluating the effectiveness of an online HIV prevention intervention for adolescent LMSM (N = 524). Only 35.5% of participants had ever had an HIV test in their lifetime. Rates of testing increased among adolescent LMSM who had a doctor with whom they spoke about their sexual health (odds ratio: 4.0; 95% confidence interval: 2.1-8.4; P < 0.001) or HIV testing (odds ratio: 5.8; 95% confidence interval: 3.1-10.7; P < 0.001). Out of the 61 participants who took part in the survey conducted in Spanish, only 26% reported ever having an HIV test. Additionally, 24.5% stated that they had discussed their sexual orientation with a doctor, and only 8.2% had undergone HIV testing. Spanish-speaking adolescents who completed the SMART survey were less likely to openly discuss their sexual orientation or sexual health with most people or have a doctor with whom they discussed these topics, compared to those who completed the survey in English. These findings suggest that Spanish-speaking adolescent LMSM may face obstacles in accessing HIV prevention services in the U.S.

RESUMEN: Los adolescentes latinos hombres que tienen sexo con otros hombres (LHSH) tienen mayor probabilidad de recibir tratamiento para el VIH más tarde en comparación con todos los casos nuevos del VIH en los Estados Unidos. Sin embargo, se ha estudiado muy poco sus prácticas de prevención de VIH o prácticas de riesgo, que similar a la de jóvenes no latinos, es determinada por múltiples factores. En este estudio describimos las tasas de pruebas para el VIH e identificamos los factores lingüísticos, individuales, familiares, escolares y de cuidado de salud que influencian a los adolescentes LHSH. Los datos provinieron de la evaluación inicial para SMART, un ensayo práctico de una intervención en línea para prevenir el VIH entre adolescentes LHSH (N = 524). Las medidas incluían la experiencia de hacerse la prueba del VIH a lo largo de la vida, factores de aculturación, datos demográficos, prácticas sexuales, educación sobre el VIH en la escuela y el hogar, comunicación sobre salud sexual con los médicos, conocimiento sobre el VIH y actitudes de riesgo. Solo 35.5% de los participantes se han realizado la prueba de VIH al menos una vez en su vida. La tasa de pruebas del VIH fue más alta entre los adolescentes LHSH que indicaron haber hablado con su médico sobre su salud sexual (odds ratio: 4.0; intervalo de confianza del 95%: 2.1­8.4; P < 0.001) o de la prueba del VIH (odds ratio: 5.8; intervalo de confianza del 95%: 3.1­10.7; P < 0.001). Más de 60 participantes completaron la encuesta en español. De estos, pocos reportaron alguna vez haberse hecho la prueba del HIV (26%), tener un médico con quien hablar sobre su orientación sexual (24.5%) o hablar sobre la prueba del VIH (8.2%). Estas cifras son significativamente más bajas que las obtenidas en la encuesta en inglés. Este estudio es uno de los primeros en evaluar los factores para hacerse la prueba del VIH entre adolescentes latinos que hablan inglés y español con edades entre 13 y 18 años. Los adolescentes latinos que completaron SMART en español tuvieron menos probabilidad de haber compartido sobre su orientación sexual con la mayoría de las personas o tener un médico con quien hablar sobre su orientación sexual o su salud sexual, en comparación con aquellos que completaron SMART en inglés, lo que sugiere que los jóvenes latinos que prefieren comunicarse en español pueden experimentar mayores barreras para acceder a los servicios de prevención del VIH en los Estados Unidos.

Identifying protective and risk behavior patterns of online communication in young people.

INTRODUCTION: Research has investigated the association between time spent online and mental well-being, however the nuances between specific online behaviors and well-being have been less explored. This research examines how specific online behaviors (i.e., how young people are engaging online and with whom), are associated with one another, and how these patterns of behaviors are related to well-being. METHODS: We used the November 2020 and March 2021 Understanding Society COVID-19 Panel data. The sample consisted of 1432 adolescents aged 10-15 years, who participated in November 2020. Latent class analysis was used to explore patterns of online behaviors. We also investigated how sociodemographic characteristics differed across the classes, along with physical, social, and mental well-being as distal outcomes both cross-sectionally and longitudinally. RESULTS: We identified four classes: "Avid users," "Scholars," "Midways," and the "Passengers." The avid users had the highest frequency of posting online content regularly, likewise the scholars also posted online content regularly, however the scholars were differentiated by their higher frequency of schoolwork and news intake online. The midways had more complex activity characterized by talking to friends often and having a social media account, but posted online content less frequently. The passengers were the least active online as they posted pictures and videos less (76% said "never") and only 63% had a social media account. The avid users had the lowest well-being cross-sectionally and longitudinally, and the midways had lower social well-being and appearance dissatisfaction. CONCLUSIONS: Online behaviors such as regularly posting or talking to internet-only friends could be related to lower well-being. Policymakers should consider both improving regulations online and building an evidence base to enable caregivers from all backgrounds to support young people.

Interpersonal theory of suicide and stressful life events in a clinical sample of adolescents in Spain.

AIMS: The interpersonal theory of suicide (ITPS) provides a theoretical model for suicidal behaviour. It includes two interpersonal variables, thwarted belongingness (TB) and perceived burdensomeness (PB). This study tested the relationship between ITPS interpersonal variables and suicide risk (presence/absence of suicidal ideation and suicide attempts throughout life) in a clinical sample of Spanish adolescents. We also assessed the potential mediation effect of these variables in the well-established relationship between stressful life events (SLE) and suicide risk. METHODS: We recruited 147 adolescents aged 11-17 from the Child and Adolescent Mental Health Outpatient Services of the Jiménez Díaz Foundation (Madrid, Spain). Different questionnaires were administered to assess suicidal behaviour and SLE (SITBI, The Stressful Life Events Scale) and to calculate proxy measures for ITPS interpersonal factors (SDQ, STAXI-NA, CDI). RESULTS: TB and PB significantly correlated with suicide risk. PB played a mediating role in the relationship between SLE and suicide risk: adolescents reporting SLE were more likely to enact suicide behaviours when they experienced higher PB. Patients scoring higher PB were more likely to receive more intense treatment but tended to abandon intervention promptly. CONCLUSIONS: ITPS seems useful for predicting suicide risk in an adolescent clinical sample. The results suggest an important role for PB in the SLE-suicide risk relationship and may impact the treatment process. Our exploratory findings should be addressed in future studies.

Medidas de proteção contra a COVID-19: impactos comunicativos, sociais e emocionais em usuários de aparelhos de amplificação sonora individual / Protective measures against COVID-19: communicative, social and emotional impacts on hearing aids users

RESUMO Objetivo investigar os impactos comunicativos, sociais e emocionais gerados pela adoção de medidas protetivas contra a COVID-19 e associá-los ao grau da perda auditiva e ao tempo de uso dos aparelhos de amplificação sonora individual. Métodos estudo transversal e quantitativo, com 72 indivíduos, divididos em adultos e idosos, com perda auditiva bilateral, de grau até moderadamente severo, protetizados antes da pandemia em um programa público de saúde auditiva e que mantiveram uso efetivo dos dispositivos. Os sujeitos foram convidados a participar do estudo enquanto aguardavam consulta. Os prontuários foram acessados, a fim de coletar informações sobre o perfil audiológico e adaptação/uso dos aparelhos de amplificação sonora individual. Em sala silenciosa, foi aplicado, oralmente, protocolo contendo questões objetivas e os dados foram tabulados e submetidos aos testes estatísticos Igualdade de Duas Proporções e Qui-Quadrado. Resultados nos dois grupos, um número significativo de usuários teve a comunicação impactada pelo uso de máscaras e pelo distanciamento físico, predominando, entre os adultos, a dificuldade com as tecnologias digitais (celulares/computadores), enquanto nas videochamadas, os prejuízos comunicativos foram mais experenciados pelos idosos. Os empecilhos comunicativos e sociais existiram, independentemente do perfil audiológico e do tempo de uso dos dispositivos. Quando questionados se deixaram de se comunicar e se as medidas afetaram a sua vida social, as respostas ficaram divididas entre "sim/às vezes" e "não". Quanto ao impacto emocional das medidas protetivas, constatou-se maior repercussão entre os adultos. Conclusão as medidas protetivas afetaram a comunicação dos usuários de aparelhos de amplificação sonora individual, porém, não desencorajaram as trocas comunicativas e as interações sociais de, aproximadamente, metade da amostra, sendo o impacto emocional mais evidente nos adultos. Tais dificuldades não estiveram relacionadas ao perfil audiológico e uso diário dos dispositivos.

ABSTRACT Purpose to investigate the communicative, social, and emotional impacts generated by adopting protective measures against COVID-19 and associate them with the degree of hearing loss and the time of use of hearing aids. Methods cross-sectional quantitative study, with 72 individuals, divided into adults and older adults, with bilateral hearing loss up to moderately severe degree, users of hearing aids fitted before the pandemic in a public hearing health program who had maintained effective use of the devices. The participants were invited to participate in the study while waiting for an appointment and signed the consent form. After that, medical records were accessed to collect information about audiological profiles and the fitting/use of hearing aids. Afterward, a protocol with objective questions was orally applied in a silent room. Data were tabulated and subjected to Equality of Two Proportions and Chi-Square statistical tests. Results in both groups, a significant number of users had communication impacted by the use of masks and by social distancing, with difficulty with digital technologies (cell phones/computers) predominating among adults, while older adults more commonly experienced communicative impairments during video calls. The communicative impediment existed regardless of the audiological profile and device use time. When asked if they stopped communicating and if the measures affected their social life, the sample was divided between "yes/sometimes" and "no". As for the emotional impact of protective measures, there was a greater impact among adults. Conclusion protective measures affected the communication of hearing aids users but did not discourage communicative exchanges and social interactions for approximately half of the sample, with the emotional impact being more evident in adults. Such difficulties were not related to the audiological profile and daily use of the devices.

Impacto de las clases virtuales en la salud mental de la población pediátrica durante la pandemia de COVID-19 en septiembre-diciembre 2021 / Impact of Virtual Classes on the Mental Health of the Pediatric Population during the COVID-19 Pandemic

Introducción: El COVID-19 ha afectado la salud mental de la población pediátrica. Con la transición a la virtualidad, se han identificado posturas positivas y negativas. Debido a la diferencia de características sociodemográficas que posee la República Dominicana, es necesario describir el efecto de dichos cambios en la salud mental dentro de este contexto. Objetivo: Evaluar el efecto de las clases virtuales en la salud mental de los pacientes pediátricos. Metodología: Se utilizó el cuestionario de capacidades y dificultades en los pacientes que asistieron a consulta general. Se asignó una puntuación con la escala de puntuación estandarizada y se analizaron los resultados en gráficos de frecuencia y pruebas de correlación de spearman. Resultados: Existe una frecuencia del 10,4% (n=34) de alto riesgo de desarrollar algún trastorno psiquiátrico. Se observaron correlaciones débiles entre menor edad y trastorno de conducta, r(365) = -0,111, p = 0,034, y sexo masculino y cualquier trastorno pediátrico, r(365) = -0,131, p = 0,012. Hay una incidencia de 51,5% de síntomas físicos. Un 45.5% y un 30.2% identificó mejores e iguales calificaciones. Conclusión: Es necesario investigar los efectos identificados agregando la evaluación de especialistas para mayor precisión de los hallazgos observados.

Introduction: COVID-19 has affected the mental health of the pediatric population. With the transition to virtuality, positive and negative positions have been identified. Due to the difference in sociodemographic characteristics that the Dominican Republic has, it is necessary to describe the effect of these changes on mental health within this context. Objective: To assess the effect of virtual classes on the mental health of pediatric patients. Methodology: Strengths and Difficulties Questionnaire was used in the patients who attended the general consultation. A score was assigned using the standardized scoring scale and the results were analyzed in frequency plots and spearman correlation tests. Results: There is a frequency of 10.4% (n=34) of high risk of developing some psychiatric disorder. Weak correlations were observed between younger age and conduct disorder, r(365) = -0.111, p = 0.034, and male gender and any pediatric disorder, r(365) = -0.131, p = 0.012. There is a 51.5% incidence of physical symptoms. 45.5% and 30.2% identified better and equal qualifications. Conclusion: It is necessary to investigate the effects identified adding the evaluation of specialists for greater precision of the observed findings.

Teleconsulta de enfermagem: desenvolvimento de plataforma para atendimento de casos de Covid-19 / Nursing teleconsultation: development of a platform for Covid-19 case management / Telecosulta en enfermería: desarrollo de una plataforma para el manejo de casos de Covid-19

Objetivo: Desenvolver uma plataforma virtual de Teleconsulta para atendimento a casos suspeitos de Síndromes Gripais e infecção por COVID-19. Metodologia: Trata-se de um estudo de natureza aplicada, com desenvolvimento de produção tecnológica e inovadora, prospectivo, ecológico, descritivo, de série temporal. A população do estudo foi formada por qualquer pessoa sintomática para Síndromes Gripais por COVID-19, suspeitos ou confirmados, de qualquer local do Brasil. Este estudo foi realizado em duas etapas, a saber: Etapa I: Desenvolvimento da Aplicação para Plataforma de Teleconsulta. Etapa II: atendimento por meio de Teleconsulta de Casos suspeitos de COVID-19 e Sindromes Gripais. A metodologia utilizada para o desenvolvimento da aplicação proposta foi a modelagem por prototipação evolucionária. Resultados: Foram realizados 209 atendimentos na Plataforma de Teleconsulta, sendo 151 (70%) do sexo feminino e 65 (30%) do sexo masculino, com prevalência de idade variando de 20 a 29 anos (41%). Quanto ao risco de infecção por COVID-19, 42 (20%) tinham alto risco, 75 (36%) médio risco e 92 (44%) baixo risco. Os sintomas mais prevalentes foram: secreção nasal ou espirros (53%), dores no corpo (49%), dor de cabeça (47%), dor de garganta (46%), tosse seca (35%), Febre (31%), falta de ar (25%) e diarreia (23%). Inicialmente o teleatendimento foi composto por teletriagem com classificação de risco com base na sintomatologia dos pacientes que foram codificados com pontuações conforme a gravidade do sintoma para formas graves de COVID-19. A classificação de risco categorizou os pacientes em risco baixo (1 a 9 pontos), risco médio (10 a 19 pontos) e risco alto (20 a 36 pontos). Em seguida, a teleconsulta foi agendada conforme disponibilidade do paciente por meio do método SBAR para comunicação efetiva e ao término do atendimento um plano de cuidados com Sistematização da Assistência de Enfermagem ­ SAE era encaminhado ao paciente por meio de WhatsApp ou e-mail. Conclusão: A plataforma de teleconsulta possibilitou a triagem dos pacientes, reduziu as visitas desnecessárias às unidades de emergência, permitiu a avaliação e monitoramento dos casos, bem como o acompanhamento de pacientes ambulatoriais que não necessitam de avaliação presencial.

Objective: To develop a virtual Teleconsultation platform for care of suspected cases of influenza syndromes and infection by COVID-19. Methodology: This is a study of applied nature, with development of technological and innovative production, prospective, ecological, descriptive, time series. The study population was made up of any person symptomatic for COVID-19 influenza syndromes, suspected or confirmed, from any location in Brazil. This study was conducted in two stages, namely: Stage I: Development of the Application for Teleconsultation Platform. Stage II: care through Teleconsultation of suspected cases of COVID-19 and influenza syndromes. The methodology used to develop the proposed application was evolutionary prototyping modeling. Results: There were 209 consultations in the Teleconsultation Platform, 151 (70%) were female and 65 (30%) were male, with prevalence of age ranging from 20 to 29 years (41%). As for the risk of infection by COVID-19, 42 (20%) had high risk, 75 (36%) medium risk and 92 (44%) low risk. The most prevalent symptoms were: nasal discharge or sneezing (53%), body aches (49%), headache (47%), sore throat (46%), dry cough (35%), fever (31%), shortness of breath (25%), and diarrhea (23%). Initially, the telecare was composed of teletry with risk classification based on the symptomatology of the patients who were coded with scores according to symptom severity for severe forms of COVID-19. The risk classification categorized patients into low risk (1 to 9 points), medium risk (10 to 19 points), and high risk (20 to 36 points). Then, the teleconsultation was scheduled according to the patient's availability through the SBAR method for effective communication and at the end of the service a care plan with Nursing Assistance Systematization - SAE was forwarded to the patient through WhatsApp or e-mail. Conclusion: Teleconsultation platform enabled patient triage, reduced unnecessary visits to emergency units, allowed the evaluation and monitoring of cases, as well as the follow- up of outpatients who do not need face-to-face evaluation.

Fight COVID Milwaukee protective behaviors and risk communications associated with the COVID-19 pandemic.

The COVID-19 pandemic has had a major impact on society, causing significant disruptions to everyday life. Risk communication strategies can play an important role in risk management as they allow individuals to prepare for and respond to public health emergencies appropriately. The aim of this study is to investigate public risk behaviors, perceptions of risk and risk communication, and experiences with COVID-19 to better understand the impact of COVID-19 on our community and to better inform public health decisions about communicating and reducing personal risk. Nine virtual focus groups were conducted with 79 residents of Milwaukee County. Audio transcripts of focus group recordings were qualitatively analyzed using MAXQDA. Predominant themes identified include public risk protective behaviors, the emotional toll associated with lockdown measures, and risk communication. Our findings provide a better understanding of how adults, African American and Hispanic groups in particular, viewed the risk communications and protective behaviors associated with COVID-19, how their lives were impacted by the pandemic, and how to effectively communicate public information about personal risk. These findings can help guide risk communication efforts and public health policy interventions for potential infection outbreaks in the future.

Potential impact of health communications to raise awareness of the relative risk of age and cancer: a qualitative study.

BACKGROUND: The Cancer Research UK Cancer Awareness Measure Survey (2022) found older age as a risk factor for cancer to be low (around 2-4% across UK nations). However, 89 in 100 cancers are in those aged 50 years and older, and the majority of health-communications are targeted to these higher risk groups. This research aimed to understand the potential impact on health behaviours of communicating messages on relative increased risk of cancer with older age on participant's capability, motivation, and opportunity (COM-B model) in relation to positive early diagnosis health behaviours (body vigilance, intention to take part in cancer screening, preventative measures). METHODS: In this qualitative study, we conducted 60 min semi-structured paired-depth interviews of people aged 25-74 years from across the UK (20 pairs; n=40; age: mean 58·5 years, range 25-74; 19 [47%] men and 21 [53%] women; 27 [67%] White and 13 [33%] from Black or Asian minority ethnic groups). Participants were recruited via a recruitment agency and provided with an incentive of £60 for their time. To assess potential longer-term impact, participants filled a survey 2 weeks later on their views on the messages tested, and on self-reported actions taken as a result of the messages tested. The three different messages tested were rotated. Data were analysed using rapid thematic techniques, two moderators reviewed the data, and a framework analysis style assessed themes against capability, opportunity, and motivation (COM-B model). FINDINGS: Message 2 was the most preferred, as it was clear and easy to understand. Results suggested that including this messaging in health campaigns could encourage some positive early diagnosis heath behaviours. The post survey identified self-reported behaviour changes in nine (23%) of the 40 participants and sustained intentions in 29 (73%). Results overlayed with COM-B, identified messaging could support behaviour change by increasing awareness (psychological capability), providing a social cue (social opportunity), and encouraging emotions related to not wanting to get cancer or that they should be doing specific behaviours (reflective motivation). INTERPRETATION: Findings suggest communicating this message might have a positive effect on help-seeking behaviours in older adults (age ≥50 years). However, considerations include ensuring that the message is clear and understandable and that it doesn't induce fear. Although this study design allowed for more in-depth exploration, results are limited due to the small sample size. FUNDING: Cancer Research UK.

Social media use and health risk behaviours in young people: systematic review and meta-analysis.

OBJECTIVES: To examine the association between social media use and health risk behaviours in adolescents (defined as those 10-19 years). DESIGN: Systematic review and meta-analysis. DATA SOURCES: EMBASE, Medline, APA PsycINFO, SocINDEX, CINAHL, SSRN, SocArXic, PsyArXiv, medRxiv, and Google Scholar (1 January 1997 to 6 June 2022). METHODS: Health risk behaviours were defined as use of alcohol, drugs, tobacco, electronic nicotine delivery systems, unhealthy dietary behaviour, inadequate physical activity, gambling, and anti-social, sexual risk, and multiple risk behaviours. Included studies reported a social media variable (ie, time spent, frequency of use, exposure to health risk behaviour content, or other social media activities) and one or more relevant outcomes. Screening and risk of bias assessments were completed independently by two reviewers. Synthesis without meta-analysis based on effect direction and random-effects meta-analyses was used. Effect modification was explored using meta-regression and stratification. Certainty of evidence was assessed using GRADE (Grading of Recommendations, Assessment, Development and Evaluations). RESULTS: Of 17 077 studies screened, 126 were included (73 included in meta-analyses). The final sample included 1 431 534 adolescents (mean age 15.0 years). Synthesis without meta-analysis indicated harmful associations between social media and all health risk behaviours in most included studies, except inadequate physical activity where beneficial associations were reported in 63.6% of studies. Frequent (v infrequent) social media use was associated with increased alcohol consumption (odds ratio 1.48 (95% confidence interval 1.35 to 1.62); n=383 068), drug use (1.28 (1.05 to 1.56); n=117 646), tobacco use (1.85, 1.49 to 2.30; n=424 326), sexual risk behaviours (1.77 (1.48 to 2.12); n=47 280), anti-social behaviour (1.73 (1.44 to 2.06); n=54 993), multiple risk behaviours (1.75 (1.30 to 2.35); n=43 571), and gambling (2.84 (2.04 to 3.97); n=26 537). Exposure to content showcasing health risk behaviours on social media (v no exposure) was associated with increased odds of use of electronic nicotine delivery systems (1.73 (1.34 to 2.23); n=721 322), unhealthy dietary behaviours (2.48 (2.08 to 2.97); n=9892), and alcohol consumption (2.43 (1.25 to 4.71); n=14 731). For alcohol consumption, stronger associations were identified for exposure to user generated content (3.21 (2.37 to 4.33)) versus marketer generated content (2.12 (1.06 to 4.24)). For time spent on social media, use for at least 2 h per day (v <2 h) increased odds of alcohol consumption (2.12 (1.53 to 2.95); n=12 390). GRADE certainty was moderate for unhealthy dietary behaviour, low for alcohol use, and very low for other investigated outcomes. CONCLUSIONS: Social media use is associated with adverse health risk behaviours in young people, but further high quality research is needed to establish causality, understand effects on health inequalities, and determine which aspects of social media are most harmful.

Toward a better understanding of cardiovascular risk in the transgender and gender-diverse community: a supplement to the Tijuana Declaration.

On World Heart Day 2022, the Mexican Society of Cardiology, the Inter-American Society of Cardiology, and the World Heart Federation collaborated on a communication regarding the increased risk of adverse cardiovascular health outcomes in transgender and gender-diverse (TGD) individuals. This document, called the Tijuana Declaration, urged the global cardiovascular community to work toward understanding and mitigating this problem. This article aims to unpack the numerous factors that lead to it. An example is the social stigma faced by members of the TGD community, which leads to increased stress and risk for cardiovascular complications. TGD patients are also more likely to have insufficient access to health care, and those that do receive care are often faced with providers that are not adequately educated about the unique needs of their community. Finally, there is some evidence to suggest that gender-affirming hormone therapies have an impact on cardiovascular health, but studies on this subject often have methodological concerns and contradictory findings. Decreasing the incidence of adverse cardiovascular events in this community requires interventions such as educational reform in the medical community, an increase in research studies on this topic, and broader social initiatives intended to reduce the stigma faced by TGD individuals.

En el Día Mundial del Corazón 2022, la Sociedad Mexicana de Cardiología, la Sociedad Interamericana de Cardiología y la Federación Mundial del Corazón colaboraron en una comunicación sobre el aumento del riesgo de resultados adversos para la salud cardiovascular en individuos transgénero y de género diverso (TGD). Este documento, conocido como la Declaración de Tijuana, instó a la comunidad cardiovascular global a trabajar en la comprensión y mitigación de este problema. Este artículo tiene como objetivo desentrañar los numerosos factores que lo provocan. Un ejemplo es el estigma social enfrentado por los miembros de la comunidad TGD, lo que conduce a un aumento del estrés y el riesgo de complicaciones cardiovasculares. Los pacientes TGD también tienen más probabilidades de tener un acceso insuficiente a la atención médica, y aquellos que la reciben a menudo se enfrentan a proveedores que no están adecuadamente educados sobre las necesidades únicas de su comunidad. Finalmente, hay evidencia que sugiere que las terapias hormonales de afirmación de género tienen un impacto en la salud cardiovascular, pero los estudios sobre este tema a menudo tienen preocupaciones metodológicas y hallazgos contradictorios. Disminuir la incidencia de eventos cardiovasculares adversos en esta comunidad requiere intervenciones como la reforma educativa en la comunidad médica, un aumento en los estudios de investigación sobre este tema e iniciativas sociales más amplias destinadas a reducir el estigma enfrentado por los individuos TGD.

Association of electronic learning devices and online learning properties with work-related musculoskeletal disorders (WMSDs): A cross-sectional study among Thai undergraduate students.

Computers and mobile devices are becoming the primary instruments used by students worldwide in all facets of their working and learning activities. This study aimed to investigate the relationship between the use of electronic devices, the characteristics of learning properties, and the potential predictors of work-related musculoskeletal disorders (WMSDs) among Thai undergraduate students. In this cross-sectional study, data were collected using Microsoft Forms with an online self-administered scale. The research instrument comprised four categories: demographic and health history characteristics, online learning properties, psychological health, and perceived WMSDs. Using multistage sampling, 4,618 samples were collected from 18 schools nationwide. A total of 3,705 respondents were eligible for the analysis. Descriptive statistics, chi-square, and binary logistic regression analyses were used for the data analysis. The results showed that the majority of the respondents had online learning only in some semesters/subjects (67.3%), used mobile phones for learning (43.3%), had an appropriate desk workstation (66.1%), used non-office chairs (76.0%), spent prolonged periods sitting (91.6%), had a bent posture while sitting (78.2%), had a private working space/room (92.4%), had proper lighting (85.4%), and experienced normal levels of stress (81.1%). Overall, 42.1% of Thai university students experienced WMSDs in any area of the body in the prior 6 months. Six significant predictors (p = 0.05) of WMSDs were obtained from the multivariate analysis, including stress, use of electronic devices, bent posture, prolonged sitting, year of study, and online learning classes (The adjusted odds ratio ranged from 1.43 to 3.67). High-risk students who mostly used mobile learning devices should be prescribed interventions to reduce stress, develop postural awareness and skills, emphasize positioning solutions, and reduce extended sitting time. The results indicated that preventive measures are warranted and required because the risk predictors were identified as preventable.

Global prevalence and content of information about alcohol use as a cancer risk factor on Twitter.

OBJECTIVES: Alcohol use is a major risk factor for several forms of cancer, though many people have limited knowledge of this link. Public health communicators and cancer advocates desire to increase awareness of this link with the long-term goal of reducing cancer burden. The current study is the first to examine the prevalence and content of information about alcohol use as a cancer risk on social media internationally. METHODS: We used a three-phase process (hashtag search, dictionary-based auto-identification of content, and human coding of content) to identify and evaluate information from Twitter posts between January 2019 and December 2021. RESULTS: Our hashtag search retrieved a large set of cancer-related tweets (N = 1,122,397). The automatic search process using an alcohol dictionary identified a small number of messages about cancer that also mentioned alcohol (n = 9061, 0.8%), a number that got small after adjusting for human coded estimates of the dictionary precision (n = 5927, 0.5%). When cancer-related messages also mentioned alcohol, 82% (n = 1003 of 1225 examined through human coding) indicated alcohol use as a risk factor. Coding found rare instances of problematic information (e.g., promotion of alcohol, misinformation) in messages about alcohol use and cancer. CONCLUSIONS: Few social media messages about cancer types that can be linked to alcohol mention alcohol as a cancer risk factor. If public health communicators and cancer advocates want to increase knowledge and understanding of alcohol use as a cancer risk factor, efforts will need to be made on social media and through other communication platforms to increase exposure to this information over time.

X Reunión Ad Hoc del Grupo Técnico Asesor (GTA) sobre Enfermedades Prevenibles por Vacunación. 31 de mayo del 2023. Reunión virtual

En julio de 2021, el Grupo Técnico Asesor (GTA) de la OPS sobre Enfermedades Prevenibles por Vacunación declaró: "La Región enfrenta una crisis inminente en torno a la vacunación sistemática". En ese momento, 1,7 millones de niños menores de un año en las Américas (14%) nunca habían recibido una sola dosis de vacuna. Brasil y México registraban aproximadamente la mitad de esta cifra. En toda la Región, 2,7 millones de niños de la misma cohorte de edad -casi uno de cada cinco- estaban subvacunados. Un año después, en julio del 2022, Estados Unidos notificó su primer caso de poliovirus derivado de la vacuna de tipo 2 (VDPV2) desde el 2013. Un mes más tarde, Canadá informó de muestras de aguas residuales positivas para VDPV2 circulante. En marzo del 2023, Perú notificó un caso confirmado de VDPV1: un niño sin antecedentes de viaje en la provincia de Loreto, en la frontera con Brasil y Colombia.  Durante su última reunión, el GTA recomendó a los países y territorios que centraran su compromiso político, técnico y financiero en detener el descenso de la cobertura de vacunación para diciembre del 2023. Dado el riesgo de importación y aparición de poliovirus circulantes de origen vacunal (cVDPV) a escala mundial, los países que aún no hayan introducido la segunda dosis de la vacuna inactivada contra la poliomielitis (IPV) deberían hacerlo inmediatamente para reducir el grupo de niños susceptibles al poliovirus de tipo 2 (PV2). Durante la reunión del 31 de mayo del 2023, la Oficina Sanitaria Panamericana presentó a los miembros del GTA una actualización de la situación de la poliomielitis en las Américas. La oficina propuso la administración conjunta de la vacuna oral contra la poliomielitis (OPV) y la IPV en respuesta a eventos o brotes de poliomielitis para seguir cerrando las brechas de inmunidad con la mayor rapidez y eficacia posibles y reforzar la inmunidad en las poblaciones de difícil acceso. La oficina también proporcionó la información más reciente sobre la vacuna hexavalente de células enteras contra la tos ferina (wP). Por último, el GTA recomendó el uso de un esquema de vacunación contra el virus del papiloma humano (VPH) de una sola dosis para todas las niñas de 9 a 14 años si se ha documentado la inmunogenicidad del producto vacunal y una inmunidad de larga duración conferida por el esquema de vacunación con una sola dosis.
