RESUMO
BACKGROUND: In the Brazilian health system, community health facilities consist of multidisciplinary teams that focus on family health, whereas health centers treat mainly illnesses of registered patients. In the present study we compared socio-economic factors and performance of mammography screening (MS) and clinical breast exam (CBE), respectively, among women who used both types of public health service centers. METHODS: The present study included 180 women aged ≥40 years, who used different health service centers within the same municipal district. Of all 180 women, 110 (41.1%) and 70 (38.9%) used a health center and a community health facility. Logistic regression analysis was performed to calculate odds ratios (ORs) and confidence intervals (CIs) of variables. RESULTS: Regression modeling indicated that women who used the community health facility, performed annual MS 9.52 (OR= 0.105; 95%CI: 0.03- 0.36) times more often (p <0.001). In this model retirement and gynecological service use ≤ each second year, increased annual MS performance 8.16 (95%CI: 1.55- 54.32) and 7.78 (95%CI: 2.54- 23.79) times (p <0.001; p <0.001). Among 113 (62.8%) women who reported strong fear of MS, the chance of its performance was 35.71 (OR= 0.028; 95%CI: 0.02- 0.32) times decreased (p= 0.05). In a second model use of gynecological service ≤ each second year, increased chance of annual CBE performance 7.92 (95%CI: 3.25- 19.29) times (p <0.001). Women who used the community health facility performed annual and bi-annual CBE 2.90 (OR= 0.345; 95%CI: 0.14- 0.86) and 2.97 (OR= 0.337; 95%CI: 0.12- 0.92) times more often, compared to women who used the health center (p =0.030). CONCLUSIONS: Performance of MS and CBE varied both considerable among women who used different types of health service centers. Gynecological service use, fear and socioeconomic variables, additionally influenced regular performance of MS and CBE.

RESUMEN Objetivo Proponer una herramienta para identificar sectores de población que requieren mayor atención por parte de autoridades locales o gubernamentales en situaciones de crisis biológica, considerando los factores que influyen en la adherencia a las normas de minimización de riesgos. Metodología Se implementó un algoritmo de ordenamiento, tomando como referencia las restricciones de julio del 2021 en Ecuador. El contexto del estudio se resume en siete sectores urbanos de la ciudad de Guayaquil, con una población caracterizada por un nivel de educación promedio por debajo de la educación secundaria superior (70%) y más del 50% entre 20-34 años, con alguna ocupación en el medio de una economía popular debilitada. Siete factores de riesgo fueron identificados después de un análisis estructural de la hipótesis de adherencia (x2/gl=3,6; CFI≥0,91; TLI≥0,90; RMSEA≤0,05), basado en una muestra aleatoria de n=515 adultos viviendo en las áreas afectadas. Resultados El seguimiento de las normas está influenciado por la percepción del clima de seguridad, el riesgo percibido y el entendimiento del riesgo. El umbral de ordenamiento (h) permite establecer relaciones unidireccionales entre variables. Conclusiones Los resultados muestran que Vergeles, Norte y Fertisa representan los sectores con mayor prioridad de atención en materia de salud pública {A4,A5,A6}>{A2}>{A3}>{A1}>{A7}. Se requiere identificar más factores para garantizar una diferenciación óptima.
ABSTRACT Objective To propose a tool to identify local communities that require public health work priority, taking into account factors that influence adherence to risk minimization guidelines, especially in lock-down environments and unconventional workplaces. Methodology An ordering algorithm, based on the theory of uncertainty, was applied to classify population zones exhibiting high levels of infection and non-compliance with regulations in Guayaquil, during the last 'weekend' lockdown episode in July 2021. Seven urban sectors showed the highest number of infections (more than 70% of the local population): Vergeles (A1), Samanes (A2), Socio Vivienda (A3), Guasmo Norte (A4), Fertisa (A5), Alborada (A6), Urdesa (A7). Seven risk factors were identified after a path analysis of compliance hypothesis (x2/gl=3,6; CFI≥0,91; TLI≥0,90, RMSEA≤0,05), based on a random sample of n=515 adults living in the affected areas. Results Adherence to norms is influenced by the safety climate, perceived risk and risk understanding. The ordering threshold (h) leaded unidirectional relationships between variables. Conclusions: Adding more factors are believed to increases the differentiation path. The results showed that Vergeles, Norte and Fertisa were the areas with the highest priority for public health care {A4,A5,A6}>{A2}>{A3}>{A1}>{A7}.
RESUMO
Resumen La Tomografía Computarizada de Haz Cónico (CBCT) representa una promisoria herramienta para la clínica odontológica. En Endodoncia, CBCT ofrece tridimensionalidad y resolución imagenológica, potenciando el diagnóstico de diferentes condiciones patológicas. Sin embargo, su limitación por sobreexposición a radiación, ha llevado a directrices que recomiendan cautela para su indicación. Se presenta un caso infrecuente de un molar mandibular con una sola raíz y canal, y las circunstancias de uso de CBCT. Mujer de 48 años es derivada para endodoncia del primer molar mandibular izquierdo permanente. El examen radiográfico preoperatorio demostró el hallazgo inusual de un canal centrado en una única raíz. Con la información apropiada y el consentimiento de la paciente, la indicación de CBCT favoreció su diagnóstico y tratamiento. CBCT no debería ser utilizada rutinariamente para estos fines, pero podría justificarse en casos "fronterizos". Se discuten su indicación e implementación clínica, siguiendo actuales recomendaciones y directrices.
Resumo A tomografia computadorizada de feixe cônico (TCFC) representa uma ferramenta promissora para a clínica odontológica. Na Endodontia, a CBCT oferece tridimensionalidade e resolução de imagem, potencializando o diagnóstico de diferentes condições patológicas. No entanto, sua limitação devido à superexposição à radiação levou a diretrizes que recomendam cautela em sua indicação. Um caso raro de um molar inferior com uma única raiz e canal é apresentado e as circunstâncias do uso da TCFC. Uma mulher de 48 anos é encaminhada para tratamento de canal para o primeiro molar inferior esquerdo permanente. O exame radiográfico pré-operatório demonstrou o achado incomum de um canal centrado em uma única raiz. Com as devidas informações e o consentimento do paciente, a indicação da TCFC favoreceu seu diagnóstico e tratamento. A CBCT não deve ser usada rotineiramente para esses fins, mas pode ser justificada em casos "fronteiriços". Sua indicação e implementação clínica são discutidas, seguindo as recomendações e diretrizes atuais.
Abstract Cone-beam computed tomography (CBCT) is a promising tool in dental practice. CBCT provides three-dimensional images and imaging resolution to be used in endodontics. This enhances the diagnosis of various pathologies. However, guidelines have recommended limiting its use due to overexposure to radiation. This article presents the rare case of a mandibular molar with a single root and canal that benefited from taking a CBCT. A 48-year-old woman is referred for endodontic treatment of the permanent left mandibular first molar. The preoperative radiographic examination showed an unusual canal centered along a single root. Taking a CBCT with the relevant information and the patient's consent improved her diagnosis and treatment. CBCTs should not be used routinely for these purposes but could be justified in "borderline" cases. This paper discusses its indication and clinical implementation following current recommendations and guidelines.
RESUMO
Abstract A scoping literature review to identify the multilevel HIV serosorting related elements was developed. Articles from EBSCO, PubMed, PsyNET and Science Direct with serosort* or serosorting at the tittle or abstract, written in English or Spanish were included. No restriction in type of population or design were applied. 239 records were retrieved after duplicates removed, but 181 references were extracted for full-text review. Individual level: HIV knowledge, serostatus, risk perceptions, abilities to disclose and for condom use negotiation, motivations, use of drugs, stigma, attitudes toward condom use, and perceptions/beliefs about the HIV and related treatments, HIV infection rates/testing and behavioral factors. Interpersonal level: social networks, abilities (sexual behavior negotiation, and communication). Community level: stigma, social norms, access to HIV related services. Structural level: political context, HIV related funding and public policies. HIV Serosorting is not solely an interpersonal behavior it involves multilevel elements that must be acknowledged by professionals and stakeholders.
Resumen Se desarrolló una revisión de alcance de la literatura para identificar elementos multinivel relacionados a la seroclasificación de VIH. Se incluyeron artículos de EBSCO, PubMed y Science Direct con serosort* o serosorting en título o resumen, escritos en Inglés o Español. No se aplicaron restricciones por tipo de población y diseño. Después de remover duplicados, se recuperaron 239 records, solo 181 referencias se extrajeron para revisión a texto completo. Nivel individual: Conocimiento del VIH, seroestado, percepciones de riesgo, habilidades para develar el seroestado y negociar el condón, motivaciones, uso de drogas, estigma, actitudes sobre uso del condón, y percepciones/ creencias acerca del VIH y tratamientos, tasas de infección y tamizaje de VIH, factores conductuales. Nivel interpersonal: redes sociales, habilidades (negociación de la conducta sexual, y comunicación). Nivel comunitario: Estigma, normas sociales, acceso a servicios de VIH. Nivel estructural: contexto político, políticas públicas y financiamiento relacionado al VIH. La seroclasificación de VIH no es solamente una conducta interpersonal, incluye elementos multinivel que deben ser reconocidos por los profesionales de salud y tomadores de decisiones.

BACKGROUND: Behavioral and social science theories/models have been gaining attention in sports injury prevention. OBJECTIVE: To investigate the potential of the Theory of Planned Behavior in explaining running-related injury preventive behavior. METHODS: Six-month prospective cohort study based on data gathered from a randomized controlled trial. From a total of 1512 invited trail runners, 232 were included in this study. Preventive behaviors and their determinants were assessed at baseline and two and six months after baseline. Five-point Likert scales were used to assess the determinants of preventive behavior. A Bayesian path analysis was conducted applying mixed models and mediation analysis. RESULTS: A 1-point increase in intention, attitude, subjective norm, and perceived behavioral control predicted an increase of 54% (95% Bayesian credible interval [BCI]: 38, 71) in the rate of performing running-related injury preventive behavior, explaining 49% (R2 0.49; 95% BCI: 0.41, 0.56) of the variance around preventive behavior. Intention and perceived behavioral control predicted running-related injury preventive behavior directly, while 40% (95% BCI: 21, 61) and 44% (95% BCI: 20, 69) of the total effect of attitude was mediated by intention and perceived behavioral control, respectively. Attitude, subjective norm, and perceived behavioral control predicted intention. CONCLUSIONS: The Theory of Planned Behavior may have the potential to explain half of the variance around running-related injury preventive behavior and intention. Therefore, such theory may be considered a relevant and useful tool in developing, investigating, and/or implementing programs aimed at preventing running-related injuries.

Diabetes prevalence is increasing worldwide, especially in low- and middle-income countries (LMIC), posing the need for improved detection and management strategies. Chronic disease models and lifestyle medicine provide structures for action. Community health workers (CHWs) can significantly contribute to chronic disease care if they are trained and integrated into low-resource health systems. Although most current CHWs worldwide are performing maternal/child health and infectious disease-related tasks, other programs involving CHWs for noncommunicable disease prevention and management are increasing. In this article, we discuss the advantages, challenges, and questions regarding possible roles assigned to CHWs in the prevention and management of diabetes. These roles include performing simple screening tests, implementing lifestyle/behavioral interventions, and connecting patients with alternatives to biomedicine. Specifically, CHWs can aid diabetes epidemiological surveillance by conducting risk score-based screening or capillary glucose testing, and they can facilitate diabetes self-management by delivering interventions described in the transcultural diabetes nutrition algorithm. Furthermore, while this role has not formally been assigned, CHWs can leverage their intimate knowledge of local practices to provide decision-making support to patients in environments with pluralistic health systems. Ethnocultural differences in CHW functions and transcultural adaptations of their roles in diabetes care should also be considered. In summary, CHWs can improve diabetes care by screening high-risk individuals and implementing lifestyle interventions, especially in LMIC.
A prevalência do diabetes está aumentando em nível global, sobretudo nos países de renda baixa e média, o que exige melhor detecção e manejo da doença. O modelo de doenças crônicas e a medicina de estilo de vida fornecem estruturas para a ação nesse sentido. Os agentes comunitários de saúde (ACS) podem contribuir de maneira significativa para a assistência às doenças crônicas, desde que sejam capacitados e integrados aos sistemas de saúde, que dispõem de recursos limitados. Embora a maioria dos ACS no mundo esteja desempenhando tarefas relacionadas à saúde materno-infantil e doenças infecciosas, estão crescendo outros programas que envolvem a prevenção e manejo das doenças não transmissíveis. O artigo discute as vantagens, desafios e questões relacionados aos possíveis papéis definidos para os ACS na prevenção e manejo do diabetes. Esses papéis incluem testes simples de triagem, implementação de intervenções comportamentais e de estilo de vida e recomendação de alternativas à biomedicina para os pacientes. Especificamente, os ACS podem auxiliar na vigilância epidemiológica do diabetes, realizando triagem baseada em pontuação de risco ou testagem de glicemia capilar, e podem facilitar o auto-manejo do diabetes através de intervenções baseadas no algoritmo nutricional transcultural do diabetes. Além disso, embora o papel não tenha sido definido formalmente, os ACS podem alavancar seu conhecimento íntimo das práticas locais para apoiar decisões pelos pacientes em contextos com sistemas de saúde pluralistas. Devem ser consideradas as diferenças etnoculturais nas funções dos ACS e nas adaptações transculturais de seus papéis durante a assistência ao diabetes. Em resumo, os ACS podem melhorar a assistência ao diabetes através da triagem e da implementação oportuna de intervenções de estilo de vida, principalmente nos países de renda baixa e média.
La prevalencia de diabetes está aumentando en todo el mundo, especialmente en los países de bajos y medios ingresos (LMIC por sus siglas en inglés), imponiendo la necesidad de una detección y gestión mejoradas. Un modelo de enfermedad crónica y la medicina del estilo de vida proporcionan estructuras para la acción. Los trabajadores comunitarios de salud (CHWs por sus siglas en inglés) pueden contribuir significativamente al cuidado de la enfermedad crónica, si son entrenados e integrados en sistemas con pocos recursos de salud. A pesar de que la mayoría de los actuales CHWs en todo el mundo están desarrollando tareas relacionadas con enfermedades infecciosas en la salud maternal/infantil, otros programas que implican a los CHWs para la prevención y gestión de enfermedades no comunicables están aumentando. En este artículo, discutimos las ventajas, desafíos, y preguntas respecto a los posibles roles asignados a los CHWs, en la prevención y gestión de la diabetes. Estos roles incluyen realizar simples pruebas de detección, implementando intervenciones de estilo de vida/comportamentales, y conectando pacientes con alternativas a la biomedicina. Específicamente, los CHWs pueden ayudar en la vigilancia epidemiológica de la diabetes, llevando a cabo pruebas de detección basadas en marcadores de riesgo o pruebas de glucosa capilares, y pueden facilitar el autocontrol de la diabetes proporcionando intervenciones descritas en el algoritmo transcultural de nutrición en diabetes. Asimismo, mientras este rol no se les haya asignado formalmente, los CHWs pueden potenciar su conocimiento profundo de prácticas locales para proporcionar apoyo en la toma de decisiones a pacientes en entornos con sistemas de salud plurales. Las diferencias etnoculturales en las funciones de los CHW y las adaptaciones transculturales de sus papeles en el cuidado de la diabetes deberían también ser consideradas. En resumen, los CHWs pueden mejorar el cuidado de la diabetes detectando e implementando oportunamente las intervenciones de estilo de vida, especialmente en LMIC.

BACKGROUND: Sperm chromatin integrity is essential for normal embryo development and pregnancy outcome. Sperm DNA fragmentation (SDF) testing constitutes a diagnostic tool to measure the proportion of spermatozoa with damaged chromatin in the ejaculate. SDF is associated with potentially treatable conditions, including varicocele, male accessory gland infections, inadequate lifestyle, and gonadotoxin exposure, thus prompting their treatment as a means of improving sperm DNA quality and the reproductive outcomes. OBJECTIVE: To provide an up-to-date review of the role of clinical and surgical interventions on SDF values in subfertile men. MATERIALS AND METHODS: An extensive search of studies examining the relationship between male infertility conditions associated with SDF was performed using PubMed and MEDLINE, with a focus on interventional therapy. The start date for the search was not defined, whereas the end date was March 2019. Randomized and non-randomized controlled trials, observational studies, systematic and narrative reviews, and case series were evaluated. RESULTS: Treating the underlying male infertility factor seems a promising way to alleviate SDF and to increase the likelihood of achieving natural and assisted conception, but data remain limited. The best evidence relates to varicocele repair and hormonal therapy with the follicle-stimulating hormone. Antioxidant therapy and lifestyle changes might alleviate oxidative sperm markers and decrease SDF but their effects on pregnancy outcomes are still unclear. Among men with high SDF undergoing assisted reproductive technology, the use of testicular spermatozoa in preference over ejaculated spermatozoa for intracytoplasmic sperm injection (ICSI) has been shown to improve pregnancy rates possibly owing to the better sperm chromatin quality in testicular spermatozoa than in ejaculated spermatozoa. CONCLUSION: Current evidence supports interventional therapy as a means to alleviate sperm DNA damage. Identification of the conditions associated with SDF remains important to enable treatment to potentially improve pregnancy outcomes but given the limited data further research is needed to determine the exact role of specific interventional therapy for subfertile men with impaired sperm chromatin.

ABSTRACT OBJECTIVE To use the advantages of a ratio scale with verbal anchors in order to measure the risk perception in the novel coronavirus infection, which causes covid-19, in a health belief model-based questionnaire, as well as its validity and reproducibility. METHOD We used the health belief model, which explores four dimensions: perceived susceptibility (five questions), perceived severity (five questions), perceived benefits (five questions), and perceived barriers (five questions). Additionally, we included a fifth dimension, called pro-health motivation (four questions). The questions composed an electronic questionnaire disseminated by social networks for an one-week period. Answers were quantitative values of subjective representations, obtained by a psychophysically constructed scale with verbal anchors ratio (CentiMax ® ). Mean time for total filling was 12 minutes (standard deviation = 1.6). RESULTS We obtained 277 complete responses to the form. One was excluded because it belonged to a participant under 18 years old. Reproducibility measures were significant for 22 of the 24 questions in our questionnaire (Cronbach's α = 0.883). Convergent validity was attested by Spearman-Brown's split half reliability coefficient (r = 0.882). Significant differences among groups were more intense in perceived susceptibility and severity dimensions, and less in perceived benefits and barriers. CONCLUSION Our health belief model-based questionnaire using quantitative measures enabled the confirmation of popular beliefs about covid-19 infection risks. The advantage in our approach lays in the possibility of quickly, directly and quantitatively identifying individual belief profiles for each dimension in the questionnaire, serving as a great ally for communication processes and public health education.
RESUMO OBJETIVO Neste estudo buscamos utilizar as vantagens de uma escala de razão por ancoragem verbal para medidas da percepção de risco de contágio pelo novo coronavírus, causador da covid-19, em um questionário baseado no modelo de crença em saúde, assim como avaliar sua validade e reprodutibilidade. MÉTODO Utilizamos o modelo de crença em saúde, o qual explora quatro dimensões: percepção individual de susceptibilidade percebida (cinco questões), severidade percebida (cinco questões), benefícios percebidos (cinco questões) e barreiras percebidas (cinco questões). Adicionalmente, incluímos uma quinta dimensão, a qual denominamos motivação pró-saúde (quatro questões). As questões definiram um questionário eletrônico que foi divulgado por redes sociais pelo período de uma semana. As respostas foram valores quantitativos de representações subjetivas, obtidas por meio de uma escala psicofísica de razão com ancoragem verbal (CentiMax ® ). O tempo médio total de preenchimento foi de 12 minutos (desvio-padrão = 1,6). RESULTADOS Obtivemos 277 respostas completas ao formulário. Uma foi excluída por se tratar de participante com menos de 18 anos de idade. Medidas de reprodutibilidade foram significantes para 22 das 24 questões de nosso questionário (α de Cronbach = 0,883). A validade convergente foi atestada pelo coeficiente de correlação de Spearman-Brown split half (r = 0,882). Diferenças significantes entre grupos foram encontradas mais intensamente nas dimensões susceptibilidade percebida e severidade percebida, e menos intensamente para benefícios percebidos e barreiras percebidas. CONCLUSÃO Nosso questionário baseado no modelo de crença em saúde utilizando medidas quantitativas permitiu evidenciar as crenças populares sobre os riscos de contágio por covid-19. A vantagem de nossa abordagem é a possibilidade de se identificar os perfis de crença individuais para cada dimensão do questionário de forma rápida, direta e quantitativa, podendo ser uma grande aliada em processos de comunicação e educação em saúde pública.

La pandemia de enfermedad por coronavirus 2019 (COVID-19) ha producido cambios sin precedentes en la comunidad médica. Los médicos y trabajadores de la salud que realizan o participan en exámenes o procedimientos de cabeza y cuello y de la vía aérea son susceptibles en alto riesgo de adquirir la infección por COVID 19 debido a la alta exposición a aerosoles y contaminación por gotas. En la actualidad se carece de datos de riesgo específico de infección. Sin embargo, los otorrinolaringólogos y cirujanos de cabeza y cuello, junto con los oftalmólogos y los odontólogos, son los grupos de mayor riesgo dentro de los profesionales de la salud debido a las áreas que examinan. Este documento se desarrolla con base en pautas encontradas en la literatura disponible más reciente. Es seguro que serán modificadas según la experiencia de cada país.
The 2019 coronavirus disease (COVID-19) pandemic has produced unprecedented changes in the medical community. Physicians and healthcare workers who perform or participate in head and neck and airway examinations and procedures are at high risk of acquiring COVID 19 infection due to high exposure to aerosols and drop contamination. Currently there is not specific infection risk data available. However, otolaryngologists and head and neck surgeons, along with ophthalmologists and dentists, are the highest risk groups within healthcare professionals due to the areas they examine. This document is developed based on guidelines found in the most recent available literature that will most likely be modified according to the experience on the pandemic of each country.
