Statins use for primary prevention of cardiovascular disease: A population-based digitally enabled real-world evidence cross-sectional study in primary care in Brazil.

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.

Assessing statins use in a real-world primary care digital strategy: a cross-sectional analysis of a population-wide digital health approach.

Background: The digitization of the primary care system provides an opportunity to evaluate the current use of statins in secondary prevention populations (myocardial infarction or stroke). Methods: We conducted a cross-sectional study (ClinicalTrials.gov, NCT05285085), analysing anonymised data routinely collected by community health workers (CHW) in Brazil between May 2016 and September 2021 to assess the proportion of self-reported statins use and associated factors. Findings: From the 2,133,900 individuals on the database, 35,103 (1.6%), mean age 66.2 years (SD14.6), 49.5% (17,382/35,103) male sex, 50.5% (17,721/35,103) female sex, and 29.6% (10,381/34,975) Caucasians, had a previous myocardial infarction (MI) (n = 11,628; 33.1%) or stroke (n = 25,925; 73.9%). Approximately 50% (17,020/35,103) were from the Northeast region, 78.7% (27,605) from urban zones, and 39.4% (13,845) with social development index (SDI) >0.7. Overall, 6.7% (2346) and 0.6% (212) reported statins and high dose statins use, respectively. Age over 60 years old (OR 1.32 [95% CI 1.19-1.47), living in the Southern region (OR 4.53 [95% CI 3.66-5.60]), having a previous diagnosis of MI (OR 4.53 [95% CI 3.66-5.60]), heart failure (OR 2.29 [95% CI 1.13-1.47]), diabetes (OR 1.50 [95% CI 1.37-1.64]), dyslipidaemia (OR 2.90 [95% CI 2.55-3.29]), chronic kidney disease (OR 1.27 [95% CI 1.08-1.48]) and use of anti-hypertensives (OR 5.47 [95% CI 4.60-6.47]) were associated with statin use. Interpretation: The analysis of a real-world database from a digitized primary care system, allowed us to identify a very low use of statins in secondary prevention Brazilian patients, mostly influenced by socio-demographic factors and co-morbidities.

Síndrome do comer noturno: aspectos conceituais, epidemiológicos, diagnósticos e terapêuticos / Night eating syndrome: conceptual, epidemiological, diagnostic and therapeutic aspects

O comportamento e o padrão alimentar são complexos, envolvendo aspectos metabólicos, fisiológicos e ambientais, e apresentando ritmicidade circadiana, herdada e espécie específica, sendo a humana essencialmente diurna. Este estudo tem como objetivo descrever a Síndrome do Comer Noturno, caracterizada por um atraso circadiano do padrão alimentar, mediado por alterações neuroendócrinas ao estresse. Procedeu-se à revisão da bibliografia existente, a partir do exame de artigos publicados pela literatura internacional nas bases de dados dos sites Pubmed, Lilacs, Sirus, referentes ao período de 1955 até as últimas publicações em 2007. Realizou-se um levantamento bibliográfico usando os seguintes descritores: night eating syndrome, sleep, circadian rhythm, appetite, nocturnal eating. Foram localizados 74 artigos e destes foram selecionados 26, cujo tema central era a Síndrome do Comer Noturno. Apesar dos estudos realizados, ainda existe longo percurso a ser percorrido para compreender a gênese da Síndrome do Comer Noturno e as relações intrínsecas desta com outros processos fisiopatogênicos. Tendo em conta que esta síndrome está vinculada ao controle da fome e da saciedade e à dessincronização entre o ritmo alimentar e o ritmo sono/vigília, a compreensão do seu processo gênico poderá demonstrar o impacto da dessincronização dos ritmos circadianos da alimentação no processo saúde-doença, e auxiliar a compreensão de fatores implicados no índice crescente de obesidade da sociedade moderna.

Behavior and eating patterns are complex, involve metabolic, physiological and environmental aspects and have inherited and species-specific circadian rhythmicity, with humans being essentially diurnal. The aim of this study is to describe the night eating syndrome, characterized by a delay of the circadian eating patterns and mediated by neuroendocrine stress. A review of the literature found in the Pubmed, Lilacs and Sirus databases published between 1955 and 2007 was done. The keywords used were: night eating syndrome, sleep, circadian rhythm, appetite, nocturnal eating. A total of 74 articles were found of which 26 were selected, whose central theme was the night eating syndrome. Despite all the studies done, there is still long way to go to understand the genesis of the night eating syndrome and its intrinsic relation with other physiological and pathogenic processes. Given that this syndrome is linked to the control of hunger and satiety and to the desynchronization between the eating rhythm and sleep / wake rhythm, understanding its genetic process can reveal the impact that the desynchronization of circadian eating rhythms has on the health-disease process and help understand the factors involved in the rising rates of obesity in modern society.
