Lung cancer risk and cancer-specific mortality in subjects undergoing routine imaging test when stratified with and without identified lung nodule on imaging study.

OBJECTIVES: To assess the risk of lung cancer and specific mortality rate in patients with and without solitary pulmonary nodules (SPN) on chest radiograph and CT. METHODS: This prospective study included 16,078 patients ≥35 years old (893 of them had an SPN detected with either chest radiograph or CT) and 15,185 without SPN. Patients were followed up for 18 months or until being diagnosed with lung cancer. Risk and mortality lung cancer were calculated in both groups with Poisson regression. RESULTS: In patients with SPN, incidence of lung cancer was 8.3 % (95 % CI 6.0-11.2) on radiograph and 12.4 % (95 % CI 9.3-15.9) on CT. A chronic obstructive pulmonary disease in patients with radiographs (odds ratio 2.62; 95 % CI 1.03, 6.67) and smoking habit (odds ratio 20.63; 95 % CI 3.84, 110.77) in patients with CT were associated with a higher probability of lung cancer. Large nodule size and spiculated edge were associated with lung cancer on both CT and radiograph. Lung cancer-specific mortality was lower in patients with SPN than in those without SPN (1.73/1000 person-years, 95 % CI 1.08-2.88 vs. 2.15/1000 person-years, 95 % CI 1.25-3.96). CONCLUSIONS: The risk of lung cancer for patients with SPN is higher in clinical populations than in screening studies. Moreover, patients with SPN showed lower mortality than those without SPN. KEY POINTS: • Lung cancer risk is 8 % for SPN detected on routine radiographs. • Lung cancer risk is 12.4 % for SPN detected in routine chest CT. • Smoking, COPD, SPN diameter and edge were predictors of malignancy. • Lung cancer risk of SPN in routine practice seems higher than in screening.

Impact of maternal depressive symptoms on offspring executive functions: a systematic review.

OBJECTIVE: This systematic review aims to thoroughly examine the current understanding of the effect of maternal depression exposure on the executive functions of offspring. METHODS: Following the PRISMA statement, a comprehensive search for peer-reviewed cohort studies was performed on Pubmed, ScienceDirect, LILACS, PsychINFO, and SciELO. Study quality was assessed using the NIH National Heart, Lung, and Blood Institute Quality Assessment Tool for Observational Cohort and Cross-sectional studies. The evidence was evaluated using the Grading of Recommendation, Assessment, Development, and Evaluation. RESULTS: This review analyzed 33 cohort studies from different countries with a total of 38,981 participants. Twenty-four studies confirmed the hypothesis of the harmful effect of maternal depressive symptoms on the performance of children's executive functions. However, a high heterogeneity among studies was found, and meta-analysis was not feasible. Fetal programming, genetics, and parental practices have been identified as potential mechanisms that can affect the executive functions of children born to mothers who have experienced depressive symptoms. CONCLUSIONS: The results suggest a negative association between maternal depressive symptoms and offspring executive functioning. Further studies on the effects of chronicity/severity of maternal symptoms and changes in executive functions in different sensitive periods are needed.

[Cardiovascular health profile of an adult population from the metropolitan region of São Paulo]. / Perfil de saúde cardiovascular de uma população adulta da região metropolitana de São Paulo.

OBJECTIVE: To describe the cardiovascular health profile of an adult population from the metropolitan region of São Paulo, according to the European Society of Cardiology (ESC) criteria. METHODS: Two hundred volunteers of both sexes enrolled in the "Cardiac Evaluation" project of a general outpatient clinic were studied. Data collected included socioeconomic status, cigarette smoking, alcohol consumption, anthropometric measurements, diet, physical activity, serum lipids, blood glucose and blood pressure. Average intake of dietary cholesterol and total lipids was estimated from a 24-hour dietary recall. Physical activity level was assessed using the International Physical Activity Questionnaire (IPAQ-8) and exercise stress tests. RESULTS: Sample population composition was 61.5% female and 38.5% male, mean age 41.7 (median = 42.6) and 41.0 (median = 43.0%). Prevalence of smoking (22%) and daily alcohol consumption (14% males; no females) was low. The overweight prevalence was 47% (12% being obese), in addition to high levels of serum total cholesterol (> 190 mg/dl) in 56% and LDL-cholesterol (> 115 mg/dl) in 61%. The IPAQ-8 results showed that 6% were sedentary. CONCLUSION: The study population showed greater risk of cardiovascular diseases, according to ESC criteria, due especially to the high prevalence of overweight and hypercholesterolemia.

Vitamin C is associated with reduced risk of cataract in a Mediterranean population.

Cataract is an important visual problem of older people and a substantial health care cost in many countries. Most studies investigating risk factors for cataract have been conducted in the United States, and there is less information on the possible role of dietary factors in European populations. We conducted a case-control study to investigate the association of antioxidant vitamins (vitamin C, vitamin E, vitamin A, beta-carotene, alpha-carotene, beta-cryptoxanthin, lycopene, zeaxanthin and lutein) and minerals (zinc and selenium) and risk of cataract in a Mediterranean population. Cases with cataract (343) and 334 age/sex frequency-matched controls aged 55 to 74 y were selected from an ophthalmic outreach clinic in Valencia, Spain. Participants were interviewed about their diet using a Food Frequency Questionnaire, and other information on potential confounders, such as smoking, alcohol, and education. Blood samples were analyzed by a colorimetric method for vitamin C and by reversed-phase HLPC for other blood antioxidants. Blood levels of vitamin C above 49 micromol/L were associated with a 64% reduced odds for cataract (P < 0.0001). Dietary intake of vitamins C, E and selenium were marginally associated with decreased odds (P = 0.09, P = 0.09, P = 0.07, respectively), whereas moderately high levels of blood lycopene (>0.30 micromol/L) were associated with a 46% increased odds of cataract (P = 0.04). Our results strengthen the evidence for a protective role for vitamin C on the aging lens as this effect was seen in a population characterized by high vitamin C intakes.

Perfil de saúde cardiovascular de uma população adulta da região metropolitana de São Paulo / Cardiovascular health profile of an adult population from the metropolitan region of São Paulo

OBJETIVO: Descrever o perfil de saúde cardiovascular de uma população adulta da região metropolitana de São Paulo, segundo critérios da Sociedade Européia de Cardiologia (SEC). MÉTODOS: Foram estudados 200 indivíduos, homens e mulheres, voluntários, participantes do projeto "Avaliação Cardiológica" de um ambulatório geral. Foram coletadas informações sobre nível socioeconômico, tabagismo, consumo de álcool, medidas antropométricas, dieta, atividade física, lipídeos séricos, glicemia e pressão arterial. A ingestão média de colesterol dietético e de lipídeos totais foi estimada a partir de recordatórios de 24 horas. Avaliou-se o nível de atividade física por meio da aplicação do Questionário Internacional de Atividade Física (IPAQ-8) e de testes de esforço. RESULTADOS: A amostra foi composta por 61,5 por cento de indivíduos do sexo feminino e 38,5 por cento, do sexo masculino, com idades médias de 41,7 anos (mediana = 42,6) e 41,0 anos (mediana = 43,0). A prevalência de tabagismo (22 por cento) e de consumo diário de álcool (14 por cento dos homens; nenhuma mulher) foi baixa. A prevalência de sobrepeso foi de 47 por cento (12 por cento de obesos), além de níveis séricos elevados de colesterol total (> 190 mg/dl) em 56 por cento dos indivíduos e de LDL-colesterol (> 115 mg/dl) em 61 por cento dos participantes. Os resultados da aplicação do IPAQ-8 mostraram 6 por cento de sedentários. CONCLUSÃO: A população de estudo apresentou maior risco de doenças cardiovasculares, segundo critérios da SEC, especialmente devido à elevada prevalência de indivíduos com sobrepeso e hipercolesterolemia.
