RESUMEN
Introdução: O conhecimento da magnitude em que a população implementa medidas de proteção emitidas pelas autoridades de saúde pública é essencial na prevenção da doença do novo coronavírus (COVID-19). A eficácia de medidas não farmacológicas de prevenção e das políticas públicas destinadas a reduzir o contágio pela COVID-19 depende de quão bem os indivíduos são informados sobre as consequências da infecção e as medidas que devem adotar para reduzir sua propagação. O entendimento, as atitudes e as práticas das pessoas em relação à COVID-19 e sua prevenção são basilares para a compreensão da dinâmica epidemiológica, demandando a realização de pesquisas sobre o cumprimento de medidas não farmacológicas de prevenção do contágio em diversos territórios. Para isso, em 2020, medidas não farmacológicas contra a COVID-19 foram divulgadas por fontes diversas, estatais e privadas, para a maior parte da população brasileira, com a finalidade de orientar comportamentos para conter a crise sanitária. As equipes da Estratégia Saúde da Família têm um papel fundamental neste processo de educação em saúde, pois compreendem elementos socioculturais das suas comunidades, alcançando-as tanto em capilaridade quanto em adequação local da informação técnico-científica. Este artigo abrange uma pesquisa de campo, parte de um projeto multicêntrico nacional. Objetivo: Avaliar se a população do território de uma unidade da Estratégia Saúde da Família da cidade de Condado-PE entende e aplica as informações que recebeu sobre medidas não farmacológicas de prevenção em suas práticas de proteção contra a COVID-19. Mais especificamente, a pesquisa visou determinar que informações foram recebidas pelos respondentes, quais as suas fontes, o grau de confiabilidade atribuído a estas, além da adesão deles às medidas não farmacológicas e sua relação com variáveis sociodemográficas. Métodos: O modelo do estudo foi observacional e descritivo, com abordagem quantitativa, a partir da coleta de dados primários com 70 usuários por entrevista presencial com questionário estruturado. Resultados: Os resultados mostraram que a população recebeu vasta informação sobre prevenção da doença. Conclusão: Com níveis variados de confiabilidade das fontes, atribuindo importância relevante às medidas de prevenção e adotou a maioria delas, com exceção do isolamento social total.
Introduction: Knowledge of the magnitude to which the population implements protective measures issued by public health authorities is essential in preventing coronavirus disease 2019 (COVID-19). The effectiveness of non-pharmacological prevention measures (NPM) and public policies aimed at reducing the spread of COVID-19 depends on how well individuals are informed about the consequences of the infection and the measures they must adopt to reduce its spread. The understanding, attitudes, and practices of people in relation to COVID-19 and its prevention are fundamental for understanding the epidemiological dynamics, demanding research on compliance with NPM to prevent contagion in different territories. To this end, in 2020, NPM against COVID-19 were released by various sources, state and private, for most of the Brazilian population, with the aim of guiding behaviors to contain the health crisis. The Family Health Strategy (FHS) teams play a key role in this health education process, as they comprise sociocultural elements of their communities, reaching them both in capillarity and in local adequacy of technical-scientific information. This article covers field research, part of a national multicenter project. Objective: To evaluate whether the population of the territory of an FHS unit in the city of Condado, Pernambuco, understands and applies the information it received about NPM prevention in their practices to protect against COVID-19. More specifically, the research aimed to determine what information was received by the respondents, what are their sources, the degree of reliability attributed to these, in addition to their adherence to the NPM and their relationship with sociodemographic variables. Methods: The study model was observational and descriptive, with a quantitative approach, based on the collection of primary data with 70 users through face-to-face interviews with a structured questionnaire. Results: The results showed that the population received extensive information on disease prevention. Conclusion: With varying levels of reliability of the sources, attributing relevant importance to prevention measures and adopted most of them, with the exception of total social isolation.
El conocimiento de la magnitud con la que la población implementa las medidas de protección emitidas por las autoridades de salud pública es fundamental en la prevención de la enfermedad por coronavirus 2019 (COVID-19). La efectividad de las medidas de prevención no farmacológicas (MFN) y de las políticas públicas dirigidas a reducir la propagación de la COVID-19 depende de qué tan bien se informe a las personas sobre las consecuencias de la infección y las medidas que deben adoptar para reducir su propagación. La comprensión, actitudes y prácticas de las personas con relación al COVID-19 y su prevención son fundamentales para comprender la dinámica epidemiológica, exigiendo investigaciones sobre el cumplimiento de las MNF para prevenir el contagio en diferentes territorios. Con ese fin, en 2020, MNF contra el COVID-19 fueron divulgados por diversas fuentes, estatales y privadas, para la mayoría de la población brasileña, con el objetivo de orientar comportamientos para contener la crisis sanitaria. Los equipos de la Estrategia de Salud de la Familia (ESF) juegan un papel fundamental en este proceso de educación en salud, ya que integran elementos socioculturales de sus comunidades, alcanzándolas tanto en la capilaridad como en la adecuación local de la información técnico-científica. Este artículo aborda una investigación de campo, parte de un proyecto multicéntrico nacional, con el objetivo de evaluar si la población del territorio de una unidad de la ESF en la ciudad de Condado-PE comprende y aplica la información recibida sobre la prevención de MNF en sus prácticas de protección contra el COVID -19. Más específicamente, la investigación tuvo como objetivo determinar qué información recibieron los encuestados, cuáles son sus fuentes, el grado de confiabilidad atribuido a estas, además de su adherencia al MNF y su relación con variables sociodemográficas. El modelo de estudio fue observacional y descriptivo, con enfoque cuantitativo, basado en la recolección de datos primarios con 70 usuarios a través de entrevistas cara a cara con un cuestionario estructurado. Los resultados mostraron que la población recibió amplia información sobre prevención de la enfermedad, con diversos niveles de confiabilidad de las fuentes, atribuyendo importancia relevante a las medidas de prevención y adoptando la mayoría de ellas, con excepción del aislamiento social total.

IMPORTANCE: Over 10 000 people with Chagas disease experience sudden cardiac death (SCD) annually, mostly caused by ventricular fibrillation. Amiodarone hydrochloride and the implantable cardioverter-defibrillator (ICD) have been empirically used to prevent SCD in patients with chronic Chagas cardiomyopathy. OBJECTIVE: To test the hypothesis that ICD is more effective than amiodarone therapy for primary prevention of all-cause mortality in patients with chronic Chagas cardiomyopathy and moderate to high mortality risk, assessed by the Rassi score. DESIGN, SETTING, AND PARTICIPANTS: CHAGASICS is an open-label, randomized clinical trial. The study enrolled patients from 13 centers in Brazil from May 30, 2014, to August 13, 2021, with the last follow-up November 8, 2021. Patients with serological findings positive for Chagas disease, a Rassi risk score of at least 10 points (intermediate to high risk), and at least 1 episode of nonsustained ventricular tachycardia were eligible to participate. Data were analyzed from May 3, 2022, to June 16, 2023. INTERVENTIONS: Patients were randomized 1:1 to receive ICD or amiodarone (with a loading dose of 600 mg after randomization). MAIN OUTCOMES AND MEASURES: The primary outcome was all-cause mortality, and secondary outcomes included SCD, hospitalization for heart failure, and necessity of a pacemaker during the entire follow-up. RESULTS: The study was stopped prematurely for administrative reasons, with 323 patients randomized (166 in the amiodarone group and 157 in the ICD group), rather than the intended 1100 patients. Analysis was by intention to treat at a median follow-up of 3.6 (IQR, 1.8-4.4) years. Mean (SD) age was 57.4 (9.8) years, 185 patients (57.3%) were male, and the mean (SD) left ventricular ejection fraction was 37.0% (11.6%). There were 60 deaths (38.2%) in the ICD arm and 64 (38.6%) in the amiodarone group (hazard ratio [HR], 0.86 [95% CI, 0.60-1.22]; P = .40). The rates of SCD (6 [3.8%] vs 23 [13.9%]; HR, 0.25 [95% CI, 0.10-0.61]; P = .001), bradycardia requiring pacing (3 [1.9%] vs 27 [16.3%]; HR, 0.10 [95% CI, 0.03-0.34]; P < .001), and heart failure hospitalization (14 [8.9%] vs 28 [16.9%]; HR, 0.46 [95% CI, 0.24-0.87]; P = .01) were lower in the ICD group compared with the amiodarone arm. CONCLUSIONS AND RELEVANCE: In patients with chronic Chagas cardiomyopathy at moderate to high risk of mortality, ICD did not reduce the risk of all-cause mortality. However, ICD significantly reduced the risk of SCD, pacing need, and heart failure hospitalization compared with amiodarone therapy. Further studies are warranted to confirm the evidence generated by this trial.

Prevention is universally advocated, especially in the case of noncommunicable diseases. However, given the proliferation of preventive technologies, it does not seem defensible to generically encourage preventive behaviors and tests for healthcare professionals and users. In this essay, we articulate concepts, ideas and criteria for considering preventive measures, providing a minimum guide to be used by professionals (especially in primary healthcare) and managers. The concepts of primary, secondary and quaternary prevention are explored, as well as those of reductive and additive prevention, high-risk and population-based preventive strategies; evidence-based medicine and its contemporary crisis; the precautionary principle; health promotion, an expanded, person-centered approach and shared decision-making. This discussion was designed to improve competence in the evaluation of preventive measures, making clinical and health decisions more judicious and less iatrogenic regarding primary and secondary prevention.
A prevenção é consensualmente defendida, especialmente para as doenças crônicas não transmissíveis. Porém, dada a proliferação de tecnologias preventivas, não parece defensável estimular genericamente condutas e exames preventivos em profissionais de saúde e usuários. Neste ensaio, apresentamos uma articulação de conceitos, ideias e critérios para a consideração de medidas preventivas, como um roteiro mínimo a ser manejado pelos profissionais (especialmente os da atenção primária à saúde) e gestores. São articulados os conceitos de: prevenção primária, secundária e quaternária; prevenção redutiva e aditiva, estratégias preventivas de alto risco e populacional; medicina baseada em evidências e sua crise contemporânea; princípio da precaução; promoção da saúde, abordagem ampliada e centrada na pessoa e decisão compartilhada. Tal articulação foi concebida visando melhorar a competência na avaliação de medidas preventivas, tornando as decisões clínicas e sanitárias mais criteriosas e menos iatrogênicas quanto à prevenção primária e secundária.

BACKGROUND: Atherosclerotic cardiovascular disease (ACVD) is worsened by chronic inflammatory diseases. Interleukin receptor antagonists (IL-RAs) and tumour necrosis factor-alpha (TNF) inhibitors have been studied to see if they can prevent cardiovascular events. OBJECTIVES: The purpose of this study was to assess the clinical benefits and harms of IL-RAs and TNF inhibitors in the primary and secondary prevention of ACVD. SEARCH METHODS: The Cochrane Heart Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), Ovid MEDLINE (including In-Process & Other Non-Indexed Citations), Ovid Embase, EBSCO CINAHL plus, and clinical trial registries for ongoing and unpublished studies were searched in February 2024. The reference lists of relevant studies, reviews, meta-analyses and health technology reports were searched to identify additional studies. No limitations on language, date of publication or study type were set. SELECTION CRITERIA: RCTs that recruited people with and without pre-existing ACVD, comparing IL-RAs or TNF inhibitors versus placebo or usual care, were selected. The primary outcomes considered were all-cause mortality, myocardial infarction, unstable angina, and adverse events. DATA COLLECTION AND ANALYSIS: Two or more review authors, working independently at each step, selected studies, extracted data, assessed the risk of bias and used GRADE to judge the certainty of evidence. MAIN RESULTS: We included 58 RCTs (22,053 participants; 21,308 analysed), comparing medication efficacy with placebo or usual care. Thirty-four trials focused on primary prevention and 24 on secondary prevention. The interventions included IL-1 RAs (anakinra, canakinumab), IL-6 RA (tocilizumab), TNF-inhibitors (etanercept, infliximab) compared with placebo or usual care. The certainty of evidence was low to very low due to biases and imprecision; all trials had a high risk of bias. Primary prevention: IL-1 RAs The evidence is very uncertain about the effects of the intervention on all-cause mortality(RR 0.33, 95% CI 0.01 to 7.58, 1 trial), myocardial infarction (RR 0.71, 95% CI 0.04 to 12.48, I² = 39%, 2 trials), unstable angina (RR 0.24, 95% CI 0.03 to 2.11, I² = 0%, 2 trials), stroke (RR 2.42, 95% CI 0.12 to 50.15; 1 trial), adverse events (RR 0.85, 95% CI 0.59 to 1.22, I² = 54%, 3 trials), or infection (rate ratio 0.84, 95% 0.55 to 1.29, I² = 0%, 4 trials). Evidence is very uncertain about whether anakinra and cankinumab may reduce heart failure (RR 0.21, 95% CI 0.05 to 0.94, I² = 0%, 3 trials). Peripheral vascular disease (PVD) was not reported as an outcome. IL-6 RAs The evidence is very uncertain about the effects of the intervention on all-cause mortality (RR 0.68, 95% CI 0.12 to 3.74, I² = 30%, 3 trials), myocardial infarction (RR 0.27, 95% CI 0.04 to1.68, I² = 0%, 3 trials), heart failure (RR 1.02, 95% CI 0.11 to 9.63, I² = 0%, 2 trials), PVD (RR 2.94, 95% CI 0.12 to 71.47, 1 trial), stroke (RR 0.34, 95% CI 0.01 to 8.14, 1 trial), or any infection (rate ratio 1.10, 95% CI: 0.88 to 1.37, I2 = 18%, 5 trials). Adverse events may increase (RR 1.13, 95% CI 1.04 to 1.23, I² = 33%, 5 trials). No trial assessed unstable angina. TNF inhibitors The evidence is very uncertain about the effects of the intervention on all-cause mortality (RR 1.78, 95% CI 0.63 to 4.99, I² = 10%, 3 trials), myocardial infarction (RR 2.61, 95% CI 0.11 to 62.26, 1 trial), stroke (RR 0.46, 95% CI 0.08 to 2.80, I² = 0%; 3 trials), heart failure (RR 0.85, 95% CI 0.06 to 12.76, 1 trial). Adverse events may increase (RR 1.13, 95% CI 1.01 to 1.25, I² = 51%, 13 trials). No trial assessed unstable angina or PVD. Secondary prevention: IL-1 RAs The evidence is very uncertain about the effects of the intervention on all-cause mortality (RR 0.94, 95% CI 0.84 to 1.06, I² = 0%, 8 trials), unstable angina (RR 0.88, 95% CI 0.65 to 1.19, I² = 0%, 3 trials), PVD (RR 0.85, 95% CI 0.19 to 3.73, I² = 38%, 3 trials), stroke (RR 0.94, 95% CI 0.74 to 1.2, I² = 0%; 7 trials), heart failure (RR 0.91, 95% 0.5 to 1.65, I² = 0%; 7 trials), or adverse events (RR 0.92, 95% CI 0.78 to 1.09, I² = 3%, 4 trials). There may be little to no difference between the groups in myocardial infarction (RR 0.88, 95% CI 0.0.75 to 1.04, I² = 0%, 6 trials). IL6-RAs The evidence is very uncertain about the effects of the intervention on all-cause mortality (RR 1.09, 95% CI 0.61 to 1.96, I² = 0%, 2 trials), myocardial infarction (RR 0.46, 95% CI 0.07 to 3.04, I² = 45%, 3 trials), unstable angina (RR 0.33, 95% CI 0.01 to 8.02, 1 trial), stroke (RR 1.03, 95% CI 0.07 to 16.25, 1 trial), adverse events (RR 0.89, 95% CI 0.76 to 1.05, I² = 0%, 2 trials), or any infection (rate ratio 0.66, 95% CI 0.32 to 1.36, I² = 0%, 4 trials). No trial assessed PVD or heart failure. TNF inhibitors The evidence is very uncertain about the effect of the intervention on all-cause mortality (RR 1.16, 95% CI 0.69 to 1.95, I² = 47%, 5 trials), heart failure (RR 0.92, 95% 0.75 to 1.14, I² = 0%, 4 trials), or adverse events (RR 1.15, 95% CI 0.84 to 1.56, I² = 32%, 2 trials). No trial assessed myocardial infarction, unstable angina, PVD or stroke. Adverse events may be underestimated and benefits inflated due to inadequate reporting. AUTHORS' CONCLUSIONS: This Cochrane review assessed the benefits and harms of using interleukin-receptor antagonists and tumour necrosis factor inhibitors for primary and secondary prevention of atherosclerotic diseases compared with placebo or usual care. However, the evidence for the predetermined outcomes was deemed low or very low certainty, so there is still a need to determine whether these interventions provide clinical benefits or cause harm from this perspective. In summary, the different biases and imprecision in the included studies limit their external validity and represent a limitation to determining the effectiveness of the intervention for both primary and secondary prevention of ACVD.

Los virus del papiloma humano (VPH) son una de las causas maÌs frecuentes de infecciones de transmisioÌn sexual en el mundo. Originan una amplia gama de enfermedades tanto en hombres como en mujeres, e incluyen lesiones premalignas que pueden progresar a caÌncer. A pesar de que la mayoriÌa de las infecciones por VPH no desarrollan siÌntomas y se resuelven espontaÌneamente, la persistencia de las mismas puede provocar enfermedad. En las mujeres, la infeccioÌn persistente por genotipos de VPH de alto riesgo oncogeÌnico es la causa principal del caÌncer cervical y de sus precursores. TambieÌn se la asocia con el desarrollo de caÌnceres orofariÌngeos y anogenitales en ambos sexos (1). El reconocimiento de los VPH de alto riesgo oncogeÌnicos como causantes del caÌncer cervical ha promovido el desarrollo de vacunas preventivas (prevencioÌn primaria), que junto con el tamizaje para la deteccioÌn temprana y el tratamiento oportuno de lesiones (prevencioÌn secun- daria) permitiraÌn reducir significativamente la incidencia del caÌncer ceÌrvico-uterino (CCU) en la Argentina en las proÌximas deÌcadas. TambieÌn permitiraÌn reducir la carga de otras enferme- dades asociadas a los VPH genitales (otros caÌnceres y verrugas genitales) tanto en hombres como en mujeres

Introduction: Primary Health Care (PHC) has acquired different meanings for different people, at specific times and places, which poses important challenges for its understanding. Objective: To analyze the meaning(s) and sense(s) of Primary/Basic Health Care in the academic views on Nursing/Health in the context of undergraduate Nursing courses offered at two public Higher Education Institutions. Materials and methods: Qualitative study with an exploratory approach. Semi-structured interviews and documentary analysis were used as data collection techniques. Results: The senses/meanings of Primary Health Care converge with the population's gateway to the health system at the first care level and with the first contact of a person with the health service. However, it is still considered as a less important service within the care network. Conclusion: Primary Health Care means a relevant possibility for Nursing/Health care through health promotion and disease prevention actions, with a commitment to respond to most of the population's health needs.

The role of aspirin in cardiovascular primary prevention remains controversial. There are physiological reasons to explore its potential benefits in patients with high levels of lipoprotein(a) [Lp(a)], mainly due to its antifibrinolytic properties and interactions with platelets. The primary objective of this systematic review was to evaluate the cardiovascular benefits and bleeding risks associated with aspirin use in patients who have elevated Lp(a) levels but no history of cardiovascular disease. This systematic review was conducted following PRISMA guidelines. We performed a literature search to identify studies assessing the cardiovascular benefits and bleeding risks of aspirin use in patients with elevated Lp(a) levels (or a related genetic variant) who have no history of cardiovascular disease. Five studies (49,871 individuals) were considered for this systematic review. Three studies assessed the impact of aspirin use in relation to genetic variants associated with elevated Lp(a) levels (SNP rs379822), while the remaining two studies directly measured plasma levels of Lp(a). The endpoints evaluated varied among the studies. Overall, the findings consistently show that carriers of the apolipoprotein(a) variant or patients with Lp(a) levels > 50 mg/dL experience a reduction in cardiovascular risk with aspirin use. No significant bleeding issues were observed, although such events were reported in only two studies. This systematic review suggests that aspirin use in patients with elevated Lp(a) levels and no prior cardiovascular history may reduce cardiovascular risk. The available data on bleeding risk is insufficient.

BACKGROUND: There are few retrospective and prospective studies on implantable cardioverter-defibrillators (ICD) in primary and secondary prevention of sudden death in chronic Chagas heart disease (CCHD). OBJECTIVES: To describe the long-term evolution of patients with CCHD and ICD and to identify and analyze predictors of mortality and appropriate device therapy in this population. METHODS: This was a historical prospective study with 117 patients with ICD and CCHD. Devices were implanted from January 2003 to December 2021. Predictors of appropriate therapies and long-term mortality were identified and analyzed. The level of statistical significance was p < 0.05. RESULTS: Patients (n = 117) had a median follow-up of 61 months (25 to 121 months); they were predominantly male (74%), with a median age of 55 years (48 to 64 years). There were 43.6% appropriate shocks, 26.5% antitachycardia pacing (ATP), and 51% appropriate therapies. During follow-up, 46 patients (39.7%) died. Mortality was 6.2% person-years (95% confidence interval [CI]: 4.6 to 8.3), with 2 sudden deaths during follow-up. Secondary prevention (hazard ratio [HR] 2.1; 95% CI: 1.1 to 4.3; p = 0.029) and ejection fraction less than 30% (HR 1.8; 95% CI: 1.1 to 3.1; p < 0.05) were predictors of appropriate therapies. Intermediate Rassi score showed a strong association with the occurrence of ATP alone (p = 0.015). Functional class IV (p = 0.007), left ventricular ejection fraction < 30 (p = 0.010), and age above 75 years (p = 0.042) were predictors of total mortality. CONCLUSION: ICDs in CCHD showed a high incidence of appropriate activation, especially in patients with secondary prevention, low left ventricular ejection fraction, and intermediate Rassi score. Patients with congestive heart failure, elevated functional class, and age over 75 years showed elevated mortality. Survival function of patients with implantable cardioverter-defibrillators and chronic Chagas heart disease. A - According to New York Heart Association functional class; B - According to left ventricular ejection fraction; C - According to Rassi score. D - According to age. CCHD: chronic Chagas heart disease; HR: hazard ratio; ICD: implantable cardioverter-defibrillator.

Background: The recommendations of both the World Cancer Research Fund (WCRF) and the American Institute for Cancer Research (AICR) for the prevention of cancer are important public health tools. These recommendations for the prevention of specific cancers are related to body weight maintenance; physical activity; foods and drinks that promote weight gain; plant foods; foods of animal origin; alcoholic beverages; preservation, processing, and preparation of food; food supplements; and breastfeeding. Methods: This study was a descriptive, cross-sectional, retrospective study. All patients provided written informed consent prior to enrollment in the study. Stratified random sampling was carried out with a convenience sample size of ≥280 participants. The characteristics of the participants were investigated using validated questions. Knowledge about the WCRF/AICR recommendations for the primary prevention of cancer was determined using 14 multiple choice questions validated in this study. Group A included participants who answered that cancer can be prevented and that lifestyle is the main factor related to the onset of cancer; the remaining participants were assigned to Group B. The χ2 test and MannâWhitney U test were used to determine differences in the groups. A p-value of ≤0.05 was considered statistically significant. A multiple linear regression analysis with gamma response was performed to assess the knowledge score. Results: A total of 289 participants were included; 168 (58%) participants were in group A, and 121 (42%) participants were in group B. Using a 0 to 14 scale, the median (P25, P75) number of correct answers was 11 (10, 12). There was no evidence of a difference between groups in sex, relationship status, literacy skills, years of education, occupation, monthly income per person, and BMI. Most of the participants reported that they did not consume tobacco (n = 259/289) or alcohol (n = 261/289) in the week prior to completing the survey. Discussion: Most of the participants (58%) considered cancer preventable and agreed that lifestyle factors were the most important factors in cancer development. The results also showed a high level of public awareness of some evidence-based associations between cancer and lifestyle factors, such as tobacco use. Some confusion among the public on other risk factors was also identified: waist circumference, a variable related to excess weight, was not identified as a risk factor for cancer by most of the participants, but the consumption of foods and beverages high in calories was identified as a risk factor by the majority of participants. Awareness of cancer protective and risk factors may lead to positive behavioral changes and eventually reduce the burden of cancer.

INTRODUCTION: A new cardiovascular risk (CVR) calculator that incorporates Lipoprotein(a) [Lp(a)] levels has recently been designed. AIMS: To estimate CVR using the new score and to identify the reduction in low-density lipoprotein cholesterol (LDL-C) or systolic blood pressure (SBP) necessary to balance the risk attributable to Lp(a). METHODS: CVR throughout life and at 10 years was estimated with the new score in patients in primary prevention, both considering and not considering the value of Lp(a). When the estimated risk considering Lp(a) levels exceeded the baseline risk, the reduction in LDL-C levels or SBP necessary to balance the risk attributable to Lp(a) was calculated. RESULTS: In total, 671 patients (mean age 54.2 years, 47.2% women) were included. Globally, 22.7% of the population had high Lp(a) values (> 50 mg/dL or > 125 nmol/L). When calculating CVR throughout life and considering the Lp(a) value, the global risk increased in 66.7% of cases (median 19.3%). Similar results were observed when we assessed the 10-year risk. The risk associated with Lp(a) could be completely compensated by decreasing LDL-C (average 21 mg/dL) or SBP (average 6.3 mmHg) in 79.2% and 74.7% of cases, respectively. CONCLUSION: When calculating the CVR with the new score, two-thirds and one-third of the population were bidirectionally recategorized as 'up' or 'down,' respectively. The decrease in LDL-C or SBP mitigated the increased risk caused by Lp(a) levels across a substantial proportion of patients.

Introducción y objetivo: Explorar las estrategias de prevención de la preeclampsia que se han propuesto a lo largo de la historia. Método: Revisión narrativa de la literatura sobre la evidencia científica histórica disponible entre 2016 y 2023 acerca de la aspirina y otras estrategias de prevención de la preeclampsia, en bases de datos bibliográficas computarizadas de estudios publicados en revistas indexadas. Resultados: Varios estudios confirman la efectividad de la aspirina para prevenir la preeclampsia en población de alto riesgo, siendo un medicamento con bajo riesgo de complicaciones, con mayor evidencia de efectividad si se inicia antes de las 16 semanas de gestación y con un aparente efecto dependiente de la dosis. Intervenciones como la disminución del consumo de sal, el reposo en cama, la suplementación con ácidos grasos, antioxidantes, L-arginina, zinc o magnesio, y el uso de diuréticos o de inhibidores de la bomba de protones, no han mostrado su utilidad en la prevención de la preeclampsia. Conclusiones: La aspirina a dosis baja es un medicamento seguro en el embarazo y efectivo para prevenir la preeclampsia en población de alto riesgo. Es la estrategia de prevención más ampliamente estudiada a lo largo de la historia para la disfunción endotelial durante la gestación.
Introduction and objective: To explore the different prevention strategies for preeclampsia that have been proposed throughout the history. Method: A narrative review of the historical, scientific evidence available between 2016 and 2021 on aspirin and other preeclampsia prevention strategies in computerized bibliographic databases of studies published in indexed journals. Results: Several studies confirm the effectiveness of aspirin to prevent preterm preeclampsia in high-risk populations, considering this as a safe drug with low risk of complications, with greater evidence of effectiveness when started before 16 weeks of gestation and apparently with a dose-dependent effect. Interventions such as reducing salt intake, bed rest, supplementation with fatty acids, antioxidants, L-arginine, zinc, magnesium, the use of diuretics or proton pump inhibitors have not shown its usefulness in the prevention of high risk preeclampsia patients. Conclusions: Low-dose aspirin is a safe drug in pregnancy and is effective to prevent preeclampsia in high-risk populations. Is the most widely studied throughout history prevention strategy for endothelial dysfunction during pregnancy.

Contextualização: A melatonina é um hormônio endógeno encontrado em quase todos os organismos e participa de vários processos fisiológicos. A suplementação de melatonina tem sido preconizada na mídia para o tratamento e prevenção de várias doenças. Entretanto, há carência de informações científicas disponíveis sobre seu real benefício para a saúde. Objetivos: Sumarizar as evidências de revisões sistemáticas da Cochrane, referentes à efetividade das intervenções com suplementação de melatonina em humanos. Métodos: Trata-se de overview de revisões sistemáticas Cochrane. Procedeu-se à busca na Cochrane Library (2023), sendo utilizado o descritor "MELATONIN". Todas as revisões sistemáticas de ensaios clínicos foram incluídas. O desfecho primário de análise foi a melhora clínica, a redução dos sintomas ou a prevenção da doença. Resultados: Oito estudos foram incluídos, totalizando 53 ensaios clínicos e 4.024 participantes. Houve evidência de efetividade apenas para controle de ansiedade em pacientes em pré-operatório (evidência moderada) em comparação com placebo e para prevenção e tratamento de jet lag de fuso horário (evidência alta de certeza). Discussão: Embora seja muito veiculada na mídia, a suplementação de melatonina carece de estudos de qualidade para análise de sua efetividade. Os estudos clínicos disponíveis até o momento são heterogêneos e apresentam limitações metodológicas. Poucas análises convergem com segurança para um bom nível de evidência que permita sua recomendação. Conclusão: Não há suporte com bom nível de evidência atualmente para a maioria das intervenções com suplementação de melatonina, sendo recomendada a realização de novos estudos prospectivos para melhor robustez dos achados e análises.

BACKGROUND: Statins are the main strategy to reduce dyslipidemia-related cardiovascular risk. Nevertheless, there is scarce evidence on the real-world statins use in primary care settings in low-middle-income countries. OBJECTIVE: We conducted a cross-sectional retrospective study using anonymized data routinely collected by community health workers in Brazil aimed to evaluate statin use and associated factors in a primary prevention population with cardiovascular risk enhancers. METHODS: Study population consisted of adults with hypertension, diabetes, and/or dyslipidemia. The primary and secondary outcomes were the proportion of individuals self-reporting statins use on any dose and high-dose statins/high-intensity lipid-lowering therapy (LLT), respectively. RESULTS: Of the 2,133,900 adult individuals in the database, 415,766 (19.5%) were included in the study cohort. From this cohort, 89.1% had hypertension, 28.9% diabetes, and 5.5% dyslipidemia. The mean age was 61.5 (standard deviation 14.5) years, 63.4% were female, and 61.0% were of mixed-race. Only 2.6% and 0.1% of individuals self-reported the use of statins and high-dose statins/high-intensity LLT, respectively. Older age (odds ratio [OR] 1.96; 95% confidence interval [CI] 1.88, 2.05, p < 0.001), living in the South region of Brazil (OR 4.39; 95% CI 3.97, 4.85, p < 0.001), heart failure (OR 2.60; 95% CI 2.33, 2.89, p < 0.001), chronic kidney disease (OR 1.49; 95% CI 1.35, 1.64, p < 0.001), and anti-hypertensive medications use (OR 4.38; 95% CI 4.07, 4.71, p < 0.001) were independently associated with statin use. CONCLUSION: In a real-world evidence study analyzing data routinely collected in a digitized primary care setting, we observed a very low use of statins in a primary prevention population with cardiovascular risk enhancers in Brazil. Socio-demographic factors and co-morbidities were associated with higher statins use rates.

INTRODUCTION: Gastric cancer (GC) is the first cause of cancer-related death in Chile and 6th in Latin America and the Caribbean (LAC). Helicobacter pylori (H. pylori) is the main gastric carcinogen, and its treatment reduces GC incidence and mortality. Esophageal-gastro-duodenoscopy (EGD) allows for the detection of premalignant conditions and early-stage GC. Mass screening programs for H. pylori infection and screening for premalignant conditions and early-stage GC are not currently implemented in LAC. The aim of this study is to establish recommendations for primary and secondary prevention of GC in asymptomatic standard-risk populations in Chile. METHODS: Two on-line synchronous workshops and a seminar were conducted with Chilean experts. A Delphi panel consensus was conducted over 2 rounds to achieve>80% agreement on proposed primary and secondary prevention strategies for the population stratified by age groups. RESULTS: 10, 12, and 12 experts participated in two workshops and a seminar, respectively. In the Delphi panel, 25 out of 37 experts (77.14%) and 28 out of 52 experts (53.85%) responded. For the population aged 16-34, there was no consensus on non-invasive testing and treatment for H. pylori, and the use of EGD was excluded. For the 35-44 age group, non-invasive testing and treatment for H. pylori is recommended, followed by subsequent test-of-cure using non-invasive tests (stool antigen test or urea breath test). In the ≥45 age group, a combined strategy is recommended, involving H. pylori testing and treatment plus non-invasive biomarkers (H. pylori IgG serology and serum pepsinogens I and II); subsequently, a selected group of subjects will undergo EGD with gastric biopsies (Sydney Protocol), which will be used to stratify surveillance according to the classification Operative Link for Gastritis Assessment (OLGA); every 3 years for OLGA III-IV and every 5 years for OLGA I-II. CONCLUSION: A "test-and-treat" strategy for H. pylori infection based on non-invasive studies (primary prevention) is proposed in the 35-44 age group, and a combined strategy (serology and EGD) is recommended for the ≥45 age group (primary and secondary prevention). These strategies are potentially applicable to other countries in LAC.

Introduction: Primary health care is a strategy that involves the different health professionals and other agents in the system who can influence the social determinants that affect human wellbeing. Objective: To know the meanings about primary health care of nursing professionals practicing in this field in a municipality of Colombia. Materials and Methods: Qualitative, exploratory, descriptive study. The research was conducted in a State Social Company (ESE for its acronym in Spanish) that provides primary health care services. Data was collected through semi-structured interviews. The sample consisted of 13 professionals. IRaMuTeQ software was used to help data interpretation. Results: 'Nurse' was the most frequent word. The content analyzed was categorized into four classes: 'Meanings about primary health care', 'nursing activities in primary health care', 'barriers encountered in primary health care', 'primary health care organization and work team'. Conclusions: Primary health care meaning is understood as the entry point of users into the health system and the one responsible for coordinating their passage through other points of the healthcare network according to users' health needs. In addition, primary health care is understood as the level of care at which essential health actions focused on the early detection of health risks and complications are carried out, so that health interventions can be planned, implemented, and evaluated on that basis.

AIMS: The use of statins has been associated with an increased risk of new-onset diabetes. The characteristics of the population could influence this association. The objective of this study was to determine the risk of new-onset diabetes with the use of statins in patients in primary prevention, with an assessment of the results according to the baseline risk of developing diabetes of the included population. METHODS: We performed an updated meta-analysis including randomized trials of statin therapy in primary prevention settings that report new-onset diabetes. The rate of new cases of diabetes in the control arms was estimated for each study. The studies were classified into two groups (low rate: < 7.5 events per 1000 patients-year; high rate; ≥ 7.5 events per 1000 patients-year). The fixed-effects model was performed. RESULTS: Eight studies (70,453 patients) were included. Globally, statin therapy was associated with an increased risk of new-onset diabetes (OR 1.1; 95% CI 1.0-1.2, I2 35%). When we analyzed the studies according to the baseline diabetes risk in the control groups, the results showed that there was a greater risk only in the studies with a high baseline rate (OR 1.2; 95% CI 1.1-1.3, I2 0%; interaction p value = 0.01). CONCLUSION: Globally, the use of statins in patients in primary prevention was associated with an increased risk of new-onset diabetes. In the stratified analysis, this association was observed only in the group of studies with a high baseline rate of events.
