ObjectiveRecent studies have shown that sex and age are associated with outcomes in patients with cardiomyopathy. The purpose of this study was to determine the all-cause mortality of dilated cardiomyopathy (DCM) by age and sex.Methods and resultsThe patients were divided into non-elderly (age <60 years, n=811) and elderly (age ≥60 years, n=331) groups. No difference in the all-cause mortality rate was observed between elderly and non-elderly patients (27.2% vs 22.2%, log-rank χ2=2.604, P=0.107). Furthermore, no significant difference in mortality was observed between the male and female patients (23.3% vs 24.5%, log-rank χ2=0.707, P=0.400). However, subgroup analysis revealed that elderly male patients exhibited a higher mortality rate than non-elderly male patients (29.4% vs 21.3%, log-rank χ2=5.898, P=0.015), while no difference was observed between the elderly female patients and non-elderly female patients. In the Cox analysis, neither age nor sex was a significant independent predictor of all-cause mortality in patients with DCM.ConclusionIn conclusion, no significant difference in mortality between male and female patients or between the elderly and non-elderly patients was observed. Only among males was a difference in mortality observed; elderly male patients experienced greater mortality than that of non-elderly male patients. No effect of age or sex on all-cause mortality was observed in patients with DCM.

Background: Available data about the effects of dietary intake on hypertension remains limited and conflicting. The purpose of this study was to assess the correlation between dietary intake and the incidence of hypertension. Methods: The China Hypertension Survey was conducted nationwide, and the data of 19,277 residents from Sichuan was organized, and finally 2,010 samples were selected into this study. Standard food frequency questionnaires were used to collect dietary intake data and physical examinations including blood pressure were performed on site. The subjects were classified into hypertensive group (n=356) and non-hypertensive group (n=1,654). The odds ratio (OR) for the occurrence of hypertension according to the quartiles of the dietary intake was evaluated by multivariable logistic regression. Results: After adjustment for all potential confounding variables, more than 50g of daily egg intake was a risk factor for hypertension prevalence (OR=2.11; 95% CI: 1.34-3.32), and 1.94-3.33g of animal oil intake per day was a protective factor (OR=0.57; 95% CI: 0.37-0.88). Conclusions: Our findings demonstrate a significant positive correlation between eggs above 50g and the risk of hypertension, while 1.94-3.33g of animal oil is negatively correlated with the risk of hypertension, indicating that adherence to a small amount of eggs and an appropriate amount of animal oil intake have beneficial effects on the prevention of hypertension.

Diabetes is a major risk factor for cardiovascular diseases, and often leads to serious cardiovascular events (peripheral arterial disease, myocardial infarction, sudden death, etc.), and coronary heart disease accounts for about 75% of the deaths of diabetes. 1,2 In diabetic patients, the incidence of asymptomatic myocardial ischemia (the patient has no subjective

Aim Preterm birth (PTB) is considered to be an important cause of neonatal mortality. However, most parts of China lack data or studies with large sample sizes to quantify the true burden of PTB. The current study aimed to determine the incidence of and factors associated with PTB in coastal areas of eastern China. Subject and methods This retrospective study included all eligible pregnant women who delivered in Lianyungang, Jiangsu Province, eastern China, between 1 July 2021 and 30 June 2022. Binary logistic regression was used to analyze the associated factors of PTB. Results A total of 29,807 pregnant women were included, and the incidence of PTB was found to be 5.1%. Multivariate regression analysis showed that pregnant women aged 18 years or younger (OR: 1.706, 95% CI: 1.207–2.409), who were 35 years or older (OR: 1.519, 95% CI: 1.312–1.760), or who had had a cesarean section delivery (OR: 1.542, 95% CI: 1.360–1.748), two or more perinatal births (OR: 14.557, 95% CI: 11.507–18.415), or four or more deliveries (OR: 1.614, 95% CI: 1.192–2.186) had a higher risk of PTB. Pregnant women with five or more prenatal visits (OR: 0.299, 95% CI: 0.241–0.372) had a lower risk of preterm delivery. In addition, pregnant women with hypertension (OR: 2.184, 95% CI: 1.666–2.863), preeclampsia (OR: 4.948, 95% CI: 3.014–8.124), gestational diabetes mellitus (OR: 1.610, 95% CI: 1.328–1.952), placenta previa (OR: 2.543, 95% CI: 1.836–3.523), or a history of PTB (OR: 9.028, 95% CI: 5.667–14.383) were more likely to have PTB. Conclusion The incidence of PTB was high and was affected by many factors. Early identification and management can reduce the incidence of PTB.
