Brazilian Guideline on Menopausal Cardiovascular Health ­ 2024 / Guía Brasileña de Salud Cardiovascular en el Climaterio y la Menopausia ­ 2024 / Diretriz Brasileira sobre a Saúde Cardiovascular no Climatério e na Menopausa ­ 2024

Women, who represent approximately half of the global population according to estimates as of January 2024, may experience signs and symptoms of menopause for at least one-third of their lives, during which they have a higher risk of cardiovascular morbidity and mortality. The effects of menopausal hormone therapy (MHT) on the progression of atherosclerosis and cardiovascular disease (CVD) events vary depending on the age at which MHT is initiated and the time since menopause until its initiation. Beneficial effects on CVD outcomes and all-cause mortality have been observed when MHT was initiated before the age of 60 or within 10 years after menopause. The decision regarding the initiation, dose, regimen, and duration of MHT should be made individually after discussing the benefits and risks with each patient. For primary prevention of postmenopausal chronic conditions, the combined use of estrogen and progestogen is not recommended in asymptomatic women, nor is the use of estrogen alone in hysterectomized women. Hormone-dependent neoplasms contraindicate MHT. For the treatment of genitourinary syndrome of menopause, vaginal estrogen therapy may be used in patients with known cardiovascular risk factors or established CVD. For women with contraindications to MHT or who refuse it, non-hormonal therapies with proven efficacy (antidepressants, gabapentin, and fezolinetant) may improve vasomotor symptoms. Compounded hormonal implants, or "bioidentical" and "compounded" hormones, and "hormone modulation" are not recommended due to lack of scientific evidence of their effectiveness and safety.

Mujeres, que representan aproximadamente la mitad de la población mundial según estimaciones de enero de 2024, pueden experimentar signos y síntomas de la menopausia durante al menos un tercio de sus vidas, durante los cuales tienen un mayor riesgo de morbilidad y mortalidad cardiovascular. Los efectos de la terapia hormonal de la menopausia (THM) en la progresión de la aterosclerosis y los eventos de enfermedad cardiovascular (ECV) varían según la edad en que se inicia la THM y el tiempo transcurrido desde la menopausia hasta su inicio. Se han observado efectos beneficiosos en los resultados de ECV y la mortalidad por todas las causas cuando la THM se inició antes de los 60 años o dentro de los 10 años posteriores a la menopausia. La decisión sobre la iniciación, dosis, régimen y duración de la THM debe tomarse individualmente después de discutir los beneficios y riesgos con cada paciente. Para la prevención primaria de condiciones crónicas en la posmenopausia, no se recomienda el uso combinado de estrógeno y progestágeno en mujeres asintomáticas, ni el uso de estrógeno solo en mujeres histerectomizadas. Las neoplasias dependientes de hormonas contraindican la THM. Para el tratamiento del síndrome genitourinario de la menopausia, se puede usar terapia estrogénica vaginal en pacientes con factores de riesgo cardiovascular conocidos o ECV establecida. Para mujeres con contraindicaciones a la THM o que la rechazan, las terapias no hormonales con eficacia demostrada (antidepresivos, gabapentina y fezolinetant) pueden mejorar los síntomas vasomotores. Los implantes hormonales compuestos, o hormonas "bioidénticas" y "compuestas", y la "modulación hormonal" no se recomiendan debido a la falta de evidencia científica sobre su efectividad y seguridad.

As mulheres, que representam cerca de metade da população mundial segundo estimativas de janeiro de 2024, podem sofrer com sinais e sintomas da menopausa durante pelo menos um terço de suas vidas, quando apresentam maiores risco e morbimortalidade cardiovasculares. Os efeitos da terapia hormonal da menopausa (THM) na progressão de eventos de aterosclerose e doença cardiovascular (DCV) variam de acordo com a idade em que a THM é iniciada e o tempo desde a menopausa até esse início. Efeitos benéficos nos resultados de DCV e na mortalidade por todas as causas ocorreram quando a THM foi iniciada antes dos 60 anos de idade ou nos 10 anos que se seguiram à menopausa. A decisão sobre o início, a dose, o regime e a duração da THM deve ser tomada individualmente após discussão sobre benefícios e riscos com cada paciente. Para a prevenção primária de condições crônicas na pós-menopausa, não se recomendam o uso combinado de estrogênio e progestagênio em mulheres assintomáticas nem o uso de estrogênio sozinho em mulheres histerectomizadas. Neoplasias hormônio-dependentes contraindicam a THM. Para tratamento da síndrome geniturinária da menopausa, pode-se utilizar terapia estrogênica por via vaginal em pacientes com fatores de risco cardiovascular conhecidos ou DCV estabelecida. Para mulheres com contraindicação à THM ou que a recusam, terapias não hormonais com eficácia comprovada (antidepressivos, gabapentina e fezolinetante) podem melhorar os sintomas vasomotores. Os implantes hormonais manipulados, ou hormônios "bioidênticos" "manipulados", e a 'modulação hormonal' não são recomendados pela falta de evidência científica de sua eficácia e segurança.

Cardiovascular diseases in women: a differentiated view and risk stratification.

Cardiovascular diseases are the main cause of mortality in men and women worldwide, surpassing mortality from all associated neoplasms. In women, its prevalence and mortality increase at menopause, but complications of reproductive age, such as preeclampsia and eclampsia, lead to increased cardiovascular risk throughout their lives. Coronary ischemic disease is is the leading cause of death in Brazil and worldwide, with atherosclerotic disease being the principal pathophysiological mechanism. However, in women, other mechanisms are associated with myocardial ischemia, such as microcirculation disease and/or vasospasm, due to the anatomical and hormonal characteristics of women in different stages of their lives. Knowledge of the most prevalent cardiovascular diseases in women, as well as the specific risk factors, the traditional ones with the greatest impact, and the under-recognized ones, is of fundamental importance in their risk stratification, diagnosis, and management, fundamentally aiming at reducing mortality.

One Size Does Not Fit All: The Need to Rethink the Metabolic Syndrome in Women

Abstract Metabolic syndrome (MetS) is increasing at epidemic proportions worldwide. MetS and its components are frequent among Brazilian women (41.8%). Women are affected by changes in adipose tissue distribution, lipid profile, insulin resistance (IR), and vascular remodeling during their lives. These changes result from the lack of estrogen after menopause. There have been various attempts to propose a uniform origin for the clustering of the MetS components, including genetics, IR, obesity, lifestyle, sleep disturbances, inflammation, fetal and neonatal programming, and disturbed circadian rhythm of the body functions. The proinflammatory and prothrombotic state in MetS is well-defined. Socioeconomic and lifestyle-related factors are also essential triggers of MetS, which is associated with a higher risk for coronary artery diseases (CAD) and stroke in women. Population measures in health and community medicine, such as continuing education on the importance of lifestyle change to reduce cardiovascular risks from early childhood, are fundamental strategies. Statins reduce high-sensitivity C-reactive protein blood levels and treat high cholesterol. According to the patient, hypoglycemic agents, such as dipeptidyl peptidase-4 (DPP-4) inhibitors, glucagon-like peptide-1(GLP-1a), and sodium-glucose transport protein 2 (SGLT2) inhibitors, in addition to metformin, have their indication due to their beneficial cardiometabolic and vascular effects. Angiotensin-converting enzyme inhibitor (ACEI) and angiotensin-receptor blocker (ARB) should be the first choice to treat hypertension in postmenopausal womem. The recognition of the different gender- and age-specific risk factors, allowing for specific and targeted interventions, is fundamental, especially for women.

Estudo observacional transversal de pacientes submetidos à oclusão percutânea de forame oval patente: uma avaliação retrospectiva de 20 anos / Cross-sectional observational study of patients submitted to percutaneous occlusion of patent foramen ovale: a 20-year retrospective analysis

Introdução: A possibilidade de shunt da direita para esquerda pelo forame oval é causa potencial de embolia paradoxal. A presença de forame oval entre os pacientes com acidente vascular cerebral isquêmico criptogênico em mais de 40% dos casos despertou interesse em avaliar o impacto de seu fechamento na redução de recidiva da doença. O estudo objetiva relatar a experiência de 20 anos com fechamento percutâneo de forame oval realizado por um único operador. Métodos: Foram submetidos a fechamento percutâneo de forame oval associado a shunt da direita para esquerda 527 pacientes com acidente vascular cerebral isquêmico. Resultados: O procedimento foi realizado com sucesso em todos os pacientes. A média da idade foi de 48 anos (9 a 72 anos), sendo 57% do sexo masculino. Foram implantadas prótese Amplatzer® em 295 pacientes (56%) e Occlutech® em 232 (44%). Não houve mortalidade, e ocorreram as seguintes complicações: hematoma no local da punção em três pacientes (0,6%); fístula arteriovenosa femoral em dois (0,4%) com resolução espontânea; tamponamento cardíaco em dois (0,4%) com resolução após punção e drenagem; arritmia supraventricular transitória em três (0,6%); cefaleia em 27 (5,1%); fibrilação atrial em dois (0,4%); shunt residual grande com necessidade de segunda prótese em dois pacientes (0,4%); recorrência de acidente vascular cerebral isquêmico em seguimento em 5 anos em quatro (0,8%) e hipersensibilidade ao níquel em uma paciente (0,2%). Conclusão: A oclusão de forame oval como prevenção de recorrência de acidente vascular cerebral isquêmico nessa série se mostrou segura, eficaz e com baixo índice de recidiva em 5 anos de seguimento.

Background: Left-to-right shunting via the foramen ovale is a potential cause of paradoxical embolism. The presence of patent foramen ovale in more than 40% of patients with idiopathic ischemic stroke has led to deeper investigation of the impact of its closure on decreasing stroke recurrence rates. This study describes 20 years of experience with percutaneous patent foramen ovale occlusion performed by a single operator. Methods: This sample comprised 527 patients with ischemic stroke submitted to percutaneous occlusion of patent foramen ovale associated to left-to- right shunting. Results: The procedure was successful in all cases. The mean age was 48 years (range of 9 to 72 years), and 57% were male. Amplatzer® and Occlutech® prostheses were implanted in 295 and 232 patients (56% and 44%, respectively). There were no deaths, and complications were as follows: hematoma at the puncture site (three patients, 0.6%), femoral arteriovenous fistula with spontaneous resolution (two patients, 0.4%), cardiac tamponade resolved after puncture and drainage (two patients, 0.4%), transient supraventricular arrhythmia (22 patients, 4.2%), headache (27 patients, 5.1%), atrial fibrillation (two patients, 0.4%), large residual shunt requiring a second prosthesis (two patients, 0.4%), recurrence of ischemic stroke within 5 years (four patients, 0.8%) and hypersensitivity to nickel (one patient, 0.2%). Conclusion: In this series, patent foramen ovale occlusion was a safe and effective alternative for prevention of recurrent ischemic stroke. Recurrence rates over the course of 5 years were low.

"Subclinical atherosclerosis in acromegaly: Possible association with cardiovascular risk factors rather than disease activity".

OBJECTIVE: Cardiovascular (CV) disease is still a major cause of excessive morbidity and mortality in patients with active acromegaly, which may be attributed to a high prevalence of associated pro-atherosclerotic risk factors. However, a direct effect of GH/IGF-1 excess on the vasculature has been previously suggested, warranting further investigation. The present study was designed to investigate whether chronic GH/IGF-1 excess is associated with an increased prevalence of subclinical atherosclerosis in patients with acromegaly. DESIGN: We measured carotid intima-media thickness (cIMT) and assessed carotid plaques by ultrasonography along with classical CV risk factors in 54 acromegaly patients (34 females, 50 ± 12 years and compared those with 62 (42 females, 53 ± 13 years) age-, sex- and CV risk factors- matched controls. In order to compare cIMT measurements between patients and controls we analyzed common carotid artery far wall data as well as a combined measurement result, which consisted of the mean value of the six different measurements, three at each side. RESULTS: mean ± SD serum GH and IGF-1 levels were 2.76 ± 4.65 ng/mL and 1.7 ± 1.25 x ULN, respectively, in all acromegaly patients. Age, body mass index, blood pressure, lipid levels, fasting glucose and Framingham's global cardiovascular risk score classification were similar comparing patients and controls. Combined median [IQR] cIMT measurements were similar in acromegaly patients and matched controls (0.59 [0.52-0.66] mm vs. 0.59 [0.52-0.69] mm; P = 0.872) as well as in acromegaly patients with active and controlled disease (0.59 [0.51-0.68] mm vs. 0.60 [0.54-0.68] mm; P = 0.385). No significant correlations were observed between cIMT measurements and GH (Spearman r = 0.1, P = 0.49) or IGF-1 (Spearman r = 0.13, P = 0.37) levels in patients with acromegaly. Carotid atherosclerotic plaques prevalence was similar in patients and controls (26% vs. 32%; P = 0.54) as well as in patients with active and controlled acromegaly (22% vs. 30%; P = 0.537). CONCLUSIONS: Our data suggest that GH/IGF-1 excess itself is not one of the main drivers of subclinical morphological atherosclerosis changes in patients with acromegaly and that optimal control of acromegaly-associated CV risk factors may preserve vasculature structure even when strict biochemical control is not achieved.

Deciduous Dental Pulp Stem Cells for Maxillary Alveolar Reconstruction in Cleft Lip and Palate Patients.

BACKGROUND: To reduce morbidity to cleft patients, new approaches have been developed and here, we report for the first time the use of deciduous dental pulp stem cells (DDPSC) associated with a hydroxyapatite-collagen sponge (Bio-Oss Collagen® 250 mg, Geistlich) for closing alveolar defects during secondary dental eruption, further comparing these results to historical controls. METHODS: Six patients, aged 8 to 12, were selected. Autologous DDPSC were isolated from each patient, then associated with the biomaterial and this bone tissue engineered set was used to fill the alveolar defect. Computed tomography was performed to assess both preoperative and 6- and 12-month postoperative outcomes. Overall morbidity was recorded. Historical controls consisted of sixteen patients previously selected and randomly assigned to group one (rhBMP-2) or group two (iliac crest bone graft). RESULTS: DDPSC could be isolated and characterized as mesenchymal stem cells. Progressive alveolar bone union has occurred in all patients. Similarly to group two 75.4%, SD ± 4.0, p > 0.999, but statistically different from group one (59.6%, SD ± 9.9, p > 0.999, but statistically different from group one (59.6%, SD ± 9.9. CONCLUSION: For this selected group of patients, DDPSC therapy resulted in satisfactory bone healing with excellent feasibility and safety, which adds significantly to the prospect of stem cell use in clinical settings. Clinical Question/Level of Evidence. Therapeutic, II. This trial is registered with https://clinicaltrials.gov/ct2/show/NCT01932164?term=NCT01932164&rank=1.

Neotropical carnivores: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non‐detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non‐governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peerreviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non‐detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio‐temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other largescale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data.

Nonsyndromic cleft lip and/or palate: A multicenter study of the dental anomalies involved.

BACKGROUND: Nonsyndromic cleft lip and/or palate (NSCL/P) is the most common craniofacial malformation. Due to the anatomical defect present in the alveolar process, these patients tend to exhibit more dental anomalies. The aim of this study was to identify the prevalence of dental anomalies in patients with NSCL/P by obtaining orthodontic documentation from Brazilian Centers for cleft lip and palate treatment. MATERIAL AND METHODS: A retrospective analysis (2000-2014) was conducted on orthodontic archives, radiographs and medical records of NSCL/P of 524 patients under orthodontic treatment. Panoramic radiographs and intra-oral photographs were examined to identify these anomalies. Categorical variables were expressed in terms of frequencies and percentages and analyzed using the Chi-Square test. The level of significance was set at p≤0.05 in all analyses. RESULTS: Approximately 83.3% of the individuals had at least one dental anomaly. Tooth agenesis was the most common abnormality found in those patients (87.8%) (p<0.001). Also, the largest number of dental anomalies was detected in the group of unilateral left clefts. The prevalence of dental anomalies in the present sample of NSCL/P patients was high and reached the highest levels in patients with alveolar bone clefts. CONCLUSIONS: This study describes the most common dental anomalies observed in patients with NSCL/P. These abnormalities can cause significant problems that may be solved or minimized by early diagnosis and treatment. Key words:Cleft lip and/or palate, dental care for children, epidemiology, craniofacial abnormalities.

Health Vulnerability Index and newborn hearing screening: urban inequality. / Índice de Vulnerabilidade à Saúde e triagem auditiva neonatal: diferenciais intraurbanos.

PURPOSE: To analyze the intra-urban differentials related to the outcome of the Newborn Hearing Screening (NHS) of children living in Belo Horizonte tested in a reference service using the Health Vulnerability Index (HVI). METHODS: cross-sectional study with children living in Belo Horizonte evaluated by a Newborn Hearing Screening Reference Service (NHSRS) between 2010 and 2011. The HVI of the census tract of each child was obtained by the georeferencing of their respective addresses. Multivariate analysis was conducted using the decision tree technique, considering a statistical model for each response. A thematic map of points representing the geographic distribution of the children evaluated by the NHS program was also developed. RESULTS: The NHS failure rate for children living in areas with very high HVI, or without HVI data, was 1.5 times higher than that for children living in other census tracts. For children living in areas of low, medium, and high HVI, who underwent NHS after 30 days of life, the NHS failure rate was 2.1 times higher in children that presented Risk Indicator for Hearing Loss (RIHL) (17.2%) than in those who did not (8.1%). Uneven distribution was observed between areas for children that underwent the NHS and those who failed it. CONCLUSION: Significant intra-urban differentials were found in Belo Horizonte, indicating correlation between health vulnerability and NHS outcomes.

Índice de Vulnerabilidade à Saúde e triagem auditiva neonatal: diferenciais intraurbanos / Health Vulnerability Index and newborn hearing screening: urban inequality

RESUMO Objetivo Analisar os diferenciais intraurbanos associados ao resultado da triagem auditiva neonatal (TAN) de crianças residentes em Belo Horizonte e avaliadas em um Serviço de Referência de TAN, tendo como referência o Índice de Vulnerabilidade à Saúde (IVS). Método Estudo observacional com amostra de crianças residentes em Belo Horizonte e avaliadas por um Serviço de Referência de TAN, entre 2010 e 2011. O IVS do setor censitário de cada criança foi obtido por georreferenciamento de seu respectivo endereço. Foi elaborado modelo estatístico para as variáveis respostas: “resultado da TAN”, “resultado no reteste”, “absenteísmo no reteste” e realizada análise multivariada, utilizando-se a técnica de árvore de decisão. Foi elaborado mapa temático de pontos para representar a distribuição espacial das crianças avaliadas pelo Programa, segundo seu resultado na TAN. Resultados A probabilidade de falhar na TAN para as crianças residentes em áreas de IVS muito elevado é 1,5 vez maior do que para as crianças residentes nas demais áreas. Para as crianças que residem em áreas de IVS baixo, médio e elevado e que fizeram a TAN após os 30 dias de vida, a probabilidade de falhar é 2,1 vezes maior nas crianças que apresentam indicador de risco para deficiência auditiva (17,2%), em relação às sem indicador de risco (8,1%). Observou-se também distribuição heterogênea de realização da TAN e de resultado da avaliação entre as regiões do município. Conclusão Foram evidenciados importantes diferenciais intraurbanos no Município de Belo Horizonte, indicando associação entre a vulnerabilidade à saúde e o resultado da TAN.
