Attainment of LDL-Cholesterol Goals in Patients with Previous Myocardial Infarction: A Real-World Cross-Sectional Analysis. / Atingimento das Metas de Colesterol LDL em Pacientes com Histórico de Infarto Agudo do Miocárdio: Estudo Transversal do Mundo Real.

BACKGROUND: The European Society of Cardiology guidelines recommend an LDL-cholesterol (LDL-C) < 55 mg/dL for patients with established cardiovascular disease. While the Friedewald equation to estimate LDL-C is still widely used, the newer Martin-Hopkins equation has shown greater accuracy. OBJECTIVES: We aimed to assess: A) the proportion of patients reaching LDL-C goal and the therapies used in a tertiary center; B) the impact of using the Martin-Hopkins method instead of Friedewald's on the proportion of controlled patients. METHODS: A single-center cross-sectional study including consecutive post-myocardial infarction patients followed by 20 cardiologists in a tertiary hospital. Data was collected retrospectively from clinical appointments that took place after April 2022. For each patient, the LDL-C levels and attainment of goals were estimated from an ambulatory lipid profile using both Friedewald and Martin-Hopkins equations. A two-tailed p-value of < 0.05 was considered statistically significant for all tests. RESULTS: Overall, 400 patients were included (aged 67 ± 13 years, 77% male). Using Friedewald's equation, the median LDL-C under therapy was 64 (50-81) mg/dL, and 31% had LDL-C within goals. High-intensity statins were used in 64% of patients, 37% were on ezetimibe, and 0.5% were under PCSK9 inhibitors. Combination therapy of high-intensity statin + ezetimibe was used in 102 patients (26%). Applying the Martin-Hopkins method would reclassify a total of 31 patients (7.8%). Among those deemed controlled by Friedewald's equation, 27 (21.6%) would have a Martin-Hopkins' LDL-C above goals. CONCLUSIONS: Less than one-third of post-myocardial infarction patients had LDL-C within the goal. Applying the Martin-Hopkins equation would reclassify one-fifth of presumably controlled patients into the non-controlled group.

FUNDAMENTO: As diretrizes da Sociedade Europeia de Cardiologia recomendam um nível de colesterol LDL (LDL-C) < 55 mg/dL para pacientes com doença cardiovascular estabelecida. Embora a fórmula de Friedewald ainda seja amplamente utilizada para estimar o LDL-C, a fórmula mais recente de Martin-Hopkins mostrou maior precisão. OBJETIVOS: Nosso objetivo foi avaliar: A) a proporção de pacientes que atingiram a meta de LDL-C e as terapias utilizadas em um centro terciário; B) o impacto da utilização do método de Martin-Hopkins em vez do método de Friedewald na proporção de pacientes controlados. MÉTODOS: Estudo transversal monocêntrico, incluindo pacientes consecutivos pós-infarto do miocárdio, acompanhados por 20 cardiologistas, em um hospital terciário. Os dados foram coletados retrospectivamente de consultas clínicas realizadas após abril de 2022. Para cada paciente, os níveis de LDL-C e o atingimento das metas foram estimados a partir de um perfil lipídico ambulatorial, utilizando as fórmulas de Friedewald e Martin-Hopkins. Um valor-p bicaudal < 0,05 foi considerado estatisticamente significativo para todos os testes. RESULTADOS: Foram incluídos 400 pacientes (com 67 ± 13 anos, 77% do sexo masculino). Utilizando a fórmula de Friedewald, a mediana de LDL-C sob terapia foi de 64 (50-81) mg/dL, e 31% tinham LDL-C dentro da meta. Estatinas de alta intensidade foram usadas em 64% dos pacientes, 37% estavam em uso de ezetimiba e 0,5% estavam em uso de inibidores de PCSK9. A terapia combinada de estatina de alta intensidade + ezetimiba foi utilizada em 102 pacientes (26%). A aplicação do método de Martin-Hopkins reclassificaria um total de 31 pacientes (7,8%). Entre aqueles considerados controlados pela fórmula de Friedewald, 27 (21,6%) teriam LDL-C estimado por Martin-Hopkins acima da meta. CONCLUSÕES: Menos de um terço dos pacientes pós-infarto do miocárdio apresentaram LDL-C dentro da meta. A aplicação da fórmula de Martin-Hopkins reclassificaria um quinto dos pacientes presumivelmente controlados no grupo de pacientes não controlados.

Heart failure worsens leg muscle strength and endurance in coexistence patients with COPD and heart failure reduced ejection fraction.

PURPOSE: Exercise intolerance and dyspnoea are clinical symptoms in both heart failure (HF) reduced ejection fraction (HFrEF) and chronic obstructive pulmonary disease (COPD), which are suggested to be associated with musculoskeletal dysfunction. We tested the hypothesis that HFrEF + COPD patients would present lower muscle strength and greater fatigue compared to compared to the COPD group. METHODS: We included 25 patients with HFrEF + COPD (100% male, age 67.8 ± 6.9) and 25 patients with COPD alone (100% male, age 66.1 ± 9.1). In both groups, COPD severity was determined as moderate-to-severe according to the GOLD classification (FEV1/FVC < 0.7 and predicted post-bronchodilator FEV1 between 30%-80%). Knee flexor-extensor muscle performance (torque, work, power and fatigue) were measured by isokinetic dynamometry in age and sex-matched patients with HFrEF + COPD and COPD alone; Functional capacity was assessed by the cardiopulmonary exercise test, the 6-min walk test (6MWT) and the four-minute step test. RESULTS: The COPD group exhibited reduced lung function compared to the HFrEF + COPD group, as evidenced by lower FEV1/FVC (58.0 ± 4.0 vs. 65.5 ± 13.9; p < 0.0001, respectively) and FEV1 (51.3 ± 17.0 vs. 62.5 ± 17.4; p = 0.026, respectively) values. Regarding musculoskeletal function, the HFrEF + COPD group showed a knee flexor muscles impairment, however this fact was not observed in the knee extensors muscles. Power peak of the knee flexor corrected by muscle mass was significantly correlated with the 6MWT (r = 0.40; p < 0.05), number of steps (r = 0.30; p < 0.05) and work ratepeak (r = 0.40; p < 0.05) in the HFrEF + COPD and COPD groups. CONCLUSION: The presence of HFrEF in patients with COPD worsens muscular weakness when compared to isolated COPD.

Impacts of the first wave of the COVID-19 pandemic on leisure and transportation physical activity among healthcare workers.

Introduction: The COVID-19 pandemic may lead to reduced physical activity (PA) in health care workers (HCWs). Objective: To evaluate leisure and transport-related PA in HCW of a COVID-19-dedicated hospital during the first wave of the COVID-19 pandemic. Methods: This is a cross-sectional study with a sample of 1,527 HCWs. Socioeconomic aspects, occupational characteristics, and engagement in leisure and transport-related PA were investigated through an online survey administered in August of 2020. Results: More than 80 % HCWs performed < 150 min/week of leisure-related PA, and 85 % performed ≤ 30 min/day transport-related PA. Being male was associated with more PA (OR: 1.93; 95 % CI:1.40-2.66) and transport-related PA; working in nursing, physical therapy, and cleaning/housekeeping services was associated with low PA (OR: 0.70; 95 % CI:0.51-0.95). Physicians and administrative staff were less active in transport-related PA. Conclusions: HCWs working in a COVID-19 hospital had low levels of PA in the domains of leisure and transportation.

Agroecologia e soberania alimentar: lutas por justiça e alimentação saudável em territórios periféricos urbanos / Agroecology and food sovereignty: Struggles for justice and healthy food in urban peripheral territories

RESUMO Neste trabalho, destacam-se aprendizados com pesquisa realizada pelo Núcleo Ecologias e Encontros de Saberes para a Promoção Emancipatória da Saúde (Neepes) em parceria com o Centro de Integração na Serra da Misericórdia (CEM) e o Movimento dos Sem Teto da Bahia (MSTB), que atuam em territórios periféricos no Rio de Janeiro e em Salvador. A pesquisa buscou apoiar e sistematizar conhecimentos e práticas emancipatórias de promoção da saúde protagonizados por essas experiências, tendo por base quatro eixos temáticos transversais: alimentação, cuidado, moradia e proteção ambiental, além de comunicação. No artigo, enfocaram-se as reflexões coletivas em relação ao primeiro eixo temático, envolvendo estratégias para promover agroecologia e soberania alimentar, com experiências de produção, circulação e acesso a alimentos saudáveis. Com base nessas reflexões, visou-se contribuir com discussões sobre Territórios Sustentáveis e Saudáveis (TSS), especialmente pelos aprendizados possibilitados com a sistematização das experiências territoriais com base na noção de Promoção Emancipatória da Saúde, que aponta para importantes aportes nas dimensões de justiça ambiental e cognitiva. Com a sistematização dessas experiências, destaca-se sua capacidade de resistir, a partir de um movimento de reexistência de saberes tradicionais e comunitários em periferias urbanas, que apontam caminhos possíveis para a construção de TSS em periferias urbanas.

ABSTRACT In this work, we highlight lessons learned from research carried out by the Nucleus Ecologies and Encounters of Knowledge for Emancipatory Health Promotion (NEEPES) in partnership with the Center of Integration in Serra da Misericórdia (CEM) and the Movement of Homeless People of Bahia (MSTB), in peripheral territories in Rio de Janeiro and Salvador. The research sought to support and systematize knowledge and emancipatory practices of health promotion carried out by these experiences, based on four transversal thematic axes: food, care, housing and environmental protection, in addition to communication. The article focused on collective reflections on the first thematic axis, involving strategies to promote agroecology and food sovereignty, with experiences of production, circulation, and access to healthy food. Based on these reflections, we aim to contribute to discussions regarding the idea of Sustainable and Healthy Territories (SHT), especially through the lessons learned from the systematization of territorial experiences based on the notion of Emancipatory Health Promotion, which points to important contributions from the dimensions of environmental and cognitive justice. The systematization of these experiences highlights a movement of re-existence of traditional and community knowledge, which points to possible paths for the construction of SHT in urban peripheries.

Illustrated booklet of Brazilian sign language for dentistry.

AIMS: This manuscript aimed to produce an illustrated booklet of Brazilian sign language (LIBRAS) booklet to facilitate the communication between dentists (and academics) and deaf patients during dental treatment and other healthcare promotion activities. METHODS AND RESULTS: A literature review was conducted to select signs, symptoms, and diseases related to dentistry expressed in LIBRAS; in addition, photographs were taken to illustrate and produce the booklet. The booklet (in PDF format) was made available on an open-access website and printed copies were freely distributed at the dental clinics of the Federal University of Pará. CONCLUSION: Learning of specific LIBRAS is extremely important to guarantee social inclusion and improve dental treatment of deaf patients.

Composition and structure of the bryophyte community of Park Savanna in Marajó Island, Pará, Brazil.

Aiming to enrich the knowledge about the flora of savannas, this paper studied the composition and structure of the bryophyte community of Park Savanna areas in Marajó Island - PA. Biological material was collected within 60 100-m2 plots equally distributed in the dry season of 2016 and the rainy season of 2017 in five Park Savanna areas (SP-I to SP-V). The composition, density, richness and diversity of species and presence of indicator species were compared between the sampled areas and seasons. The species were classified according to the substrates colonized and ecological groups of light tolerance. Significant differences in SP-V indicated that the area was the main factor influencing the composition of bryophytes (p: 0.0001), with five indicator species. There were also significant differences in density (p = 0.0001168) and richness (p = 0.0001317) of bryophytes between seasons (p-value = 0.3393; p-value = 0.04065; p: 0.1081). There was a predominance of generalist (25 spp.) and corticolous (728 individuals) species, which were widely distributed in the sampled areas. Therefore, the structure of the bryophyte communities was not influenced by seasonality, and this indicates that these plants are adapted to the environmental conditions.

Alterações cardiorrespiratórias em indivíduos hemiparéticos crônicos pós-acidente vascular cerebral / Cardiorespiratory changes in chronic post-stroke hemiparetic patients

Objetivo: Analisar a função cardiorrespiratória em pacientes he- miparéticos crônicos pós-acidente vascular cerebral. Métodos: Estudo retrospectivo, por meio da análise de dados de prontuários de pacientes submetidos ao teste de caminhada de 6 minutos e manovacuometria em uma clínica de fisioterapia de um centro universitário. Foram analisados os dados de sete prontuários. Re- sultados: A média de metros percorridos pelos participantes no teste de caminhada de 6 minutos foi de 199,5. Os valores percentuais da manovacuometria foram de -41,34 na pressão inspiratória máxima e de 57,85 na pressão expiratória máxima. Conclusão: Os dados desta pesquisa sugerem que indivíduos hemiparéticos crônicos apresentam fadiga respiratória e muscular, diminuição da capacidade funcional durante a marcha e fraqueza dos músculos respiratórios.

Objective: To analyze the cardiorespiratory function in chronic post-stroke hemiparetic patients. Methods: This is a retrospective study, through data analysis of medical records from patients who underwent the 6-minute walk test and manovacuometry, in a physical therapy clinic of a university center. Results: The mean number of meters walked by participants in the 6-minut walk test was 199.5 meters. The percentage values of manovacuometry were -41,34 in the maximun inspiratory pressure and 57.85 in the maximun expiratory pressure. Conclusion: The data from this survey suggest that chronic hemiparetic individuals have respiratory and muscle fatigue, decreased functional capacity during gait, and respiratory muscle weakness.

Premature or Small for Gestational Age Discrimination: International Multicenter Trial Protocol for Classification of the Low-Birth-Weight Newborn Through the Optical Properties of the Skin.

BACKGROUND: A low birth weight is an independent risk factor for adverse infant outcomes and a predictor of chronic disease in adulthood. In these situations, differentiating between prematurity and small for gestational age (SGA) or simultaneous conditions is essential to ensuring adequate care. Such diagnoses, however, depend on reliable pregnancy dating, which can be challenging in developing countries. A new medical optoelectronic device was developed to estimate gestational age (GA) at birth based on newborn skin reflection. OBJECTIVE: This study will aim to evaluate the device's ability to detect prematurity or SGA, or both conditions simultaneously as well as predict short-term pulmonary complications in a cohort of low-birth-weight newborns. METHODS: This study protocol was designed for a multicenter cohort including referral hospitals in Brazil and Mozambique. Newborns weighing 500-2500 g will be eligible for inclusion with the best GA available, considering the limited resources of low-income countries. Comparator-GA is based on reliable last menstrual period dating or ultrasound assessment before 24 weeks' gestation. Estimated GA at birth (Test-GA) will be calculated by applying a novel optoelectronic device to the newborn's skin over the sole. The average difference between Test-GA and Comparator-GA will be analyzed, as will the percentage of newborns who are correctly diagnosed as preterm or SGA. In addition, in a nested case-control study, the accuracy of skin reflection in the prediction of prematurity-related respiratory problems will be evaluated. The estimated required sample size is 298 newborns. RESULTS: Teams of health professionals were trained, and standard operating procedures were developed following the good practice guidelines for the clinical investigation of medical devices for human participants. The first recruitment started in March 2019 in Brazil. Data collection is planned to end in December 2020, and the results should be available in March 2021. CONCLUSIONS: The results of this clinical study have the potential to validate a new device to easily assess postnatal GA, supporting SGA identification when pregnancy dating is unreliable or unknown.

Time Effect of Intra-articular Injection With Triamcinolone Hexacetonide and Its Correlations: A Case-Control Prospective 12-Month Study.

OBJECTIVE: The aim of the study was to assess the time effect of intra-articular injection with triamcinolone hexacetonide in rheumatic patients. DESIGN: A prospective case-control study with patients submitted to one intra-articular injection with triamcinolone hexacetonide. Patients were followed monthly (12 mos) for pain and swelling. RESULTS: Two hundred sixty-two joints were assessed in 158 patients with mean ± SD age of 60 ± 13.7 yrs. Remission was observed at 3, 6, and 12 mos in 142 (54.19%), 111 (42.36%), and 105 (40.07%) joints, respectively. The mean ± SD time effect were 8 ± 4.0 mos; 8.4 ± 3.9 for rheumatoid arthritis patients and 6.9 ± 4.0 for osteoarthritis patients (P = 0.012) and 10.4 ± 2.7 mos for small, 7.7 ± 4.1 for medium, and 6.8 ± 4.0 for large joints. The joints were divided into two groups: long-term group (time effect of intra-articular injection longer than 6 mos) and short-term group. The following are the variables associated (P < 0.05) with long-term group: rheumatoid arthritis, small and medium-sized joints, female sex, lower pain and swelling visual analog scale scores, and use of leflunomide. The following are the variables associated with short-term group: receiving only one intra-articular injection, hypertension, diabetes mellitus, and biological therapy. CONCLUSIONS: The mean ± SD time effect of intra-articular injection with triamcinolone hexacetonide was 8.0 ± 4.0 mos. The associated predictors were rheumatoid arthritis, small and medium joints, lower pain/swelling visual analog scale scores, and use of leflunomide.

Assessing the impact of Medical Microbiology classes using active strategies on short- and long-term retention on medical students: an innovative study.

One of teachers' concerns, with students in general and medical students in particular, is to ensure as much as possible that information goes from students' short-term memories to their long-term memories. The present study focuses on knowledge retention in Medical Microbiology and assesses the effectiveness of some strategies implemented for short- and long-term retention. A pre- and post-test was used to assess student's learning. This study involved students of Porto University (test group). Test group participants were all attending the third year of the Medicine Degree Program. The results of post-test 1 were considered very positive and support the importance of these applied active activities and/or methodologies in Medical Microbiology for short-term retention. However, the results obtained in post-test 2 showed that knowledge retention after 9 months, despite substantial, decreases.

Análise da concentração de cloro ativo em sanitizantes industrializados comercializados em Maceió, AL

No Brasil, do ano de 2000 a 2017, ocorreram 12.503 surtos de origem alimentar e os locais que sobressaíram como os mais frequentes na ocorrência destes surtos foram restaurantes e residências tendo como uma das causas principais, as superfícies de equipamentos, utensílios e objetos mal higienizados. O produto mais usado para realizar a higiene é o hipoclorito de sódio (água sanitária), sendo este utilizado tanto para serviços de alimentação como para uso residencial. O hipoclorito é comercializado industrialmente e este pode ser fabricado de forma impropria não correspondendo ao percentual de cloro contido em sua rotulagem. O objetivo deste estudo foi analisar o teor de cloro das marcas comerciais de águas sanitárias industrializadas comercializadas na cidade de Maceió/AL. A metodologia utilizada para determinação de Cloro Ativo foi o método volumétrico, em solução de hipoclorito de sódio. Duas marcas comerciais apresentaram valores menores que 2% de cloro, sete com valores acima e três com valores entre 2 e 2,5%, valores estes preconizados pela legislação. Os resultados mostram que a fabricação deste produto precisa de fiscalização por órgãos competentes para que o teor de cloro esteja dentro do padrão da Legislação. Com essa inadequação a população será prejudicada, pois estará comprando um produto adulterado

In Brazil, from the year 2000 to 2017, 12,503 foodborne outbreaks have occurred, and the other important local as the more frequent occurrence of these outbreaks was restaurants and residences having as one of the main causes, the surfaces of equipment, utensils and objects poorly sanitized. The product used to perform hygiene is sodium hypochlorite (bleach), which is used for both food service as for residential use. The hypochlorite is sold industrially and this can be manufactured in a manner unbecoming not corresponding to the percentage of chlorine contained in your labelling. The aim of this study was to analyze the chlorine content of the trademarks of sanitary water marketed in the industrialised city of Maceió/AL. The methodology used for the determination of active chlorine, was using the volumetric method, solution of sodium hypochlorite. Two trademarks presented values less than 2% chlorine, seven with values above and 3 with values between 2 and 2.5%, these values provided by the legislation. The results show that the manufacture of this product needs supervision by competent bodies so that the chlorine content is within the pattern of legislation. With this inadequacy to population will suffer, as will be buying an adulterated product
