Cardiovascular Risk Factors in Patients with Valvular Heart Disease: A Nationwide Observational Cohort Study.

Purpose: Conventional cardiovascular risk factors may contribute to the development of valvular heart disease (VHD). The present study sought to investigate the distribution of conventional modifiable cardiovascular risk factors (smoking, hypertension, hyperlipidemia, and diabetes) in various VHDs, the impact of risk factors on outcomes, and the prognostic indicators in patients with distinct burdens of risk factors.

Patients And Methods: The study included 11862 patients with moderate or greater VHD.

This study aimed to investigate the prevalence of diabetes in valvular heart disease (VHD), as well as the relationship of diabetes with severity of valvular lesions and clinical outcome. A total of 11,862 patients with significant (≥moderate) VHD from the China Valvular Heart Disease study were included in the analysis. The primary outcome was the composite of all-cause death, hospitalization for heart failure, and myocardial infarction during two-year follow-up.

Meta-Analysis Global Group in Chronic Heart Failure score for the prediction of mortality in valvular heart disease.

Aims: Valvular heart disease (VHD) is one of the leading causes of heart failure. Clinically significant VHD can induce different patterns of cardiac remodelling, and risk stratification is challenging in patients with various degrees of cardiac dysfunction. The study aimed to investigate the prognostic implications of Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC) score in patients with VHD.

Total Cholesterol Levels and Risk of Mortality or Heart Failure Rehospitalization in Patients With Valvular Heart Disease.

Low total cholesterol (TC) levels have been found to significantly increase mortality risk in patients experiencing heart failure. However, it is unclear whether the same relation applies specifically to patients with valvular heart disease (VHD). This study included patients with significant VHD from the China Valvular Heart Disease Study.

Development and validation of a score predicting mortality for older patients with mitral regurgitation.

Objective: To develop and validate a user-friendly risk score for older mitral regurgitation (MR) patients, referred to as the Elder-MR score.

Methods: The China Senile Valvular Heart Disease (China-DVD) Cohort Study functioned as the development cohort, while the China Valvular Heart Disease (China-VHD) Study was employed for external validation. We included patients aged 60 years and above receiving medical treatment for moderate or severe MR (2274 patients in the development cohort and 1929 patients in the validation cohort).

Assessment of cardio-renal-hepatic function in patients with valvular heart disease: a multi-biomarker approach-the cardio-renal-hepatic score.

Background: Valvular heart disease (VHD) can cause damage to extra-cardiac organs, and lead to multi-organ dysfunction. However, little is known about the cardio-renal-hepatic co-dysfunction, as well as its prognostic implications in patients with VHD. The study sought to develop a multi-biomarker index to assess heart, kidney, and liver function in an integrative fashion, and investigate the prognostic role of cardio-renal-hepatic function in VHD.

Effects of hole shape and bottom gap on the flow characteristics behind butterfly porous fence and its application in dust diffusion control in large open-air piles.

In view of the possible dust pollution of atmospheric caused by large open-air piles, a scheme of using butterfly porous fences is proposed. Based on the actual cause of large open-air piles, this study makes an in-depth study on the wind shielding effect of butterfly porous fences. The effects of hole shape and bottom gap on the flow characteristics are investigated behind the butterfly porous fence with the porosity of 0.

Prognostic value of blood pressure and resting heart rate in patients with tricuspid regurgitation.

Background: The prognostic value of blood pressure (BP) and resting heart rate (RHR) in tricuspid regurgitation (TR) patients is unknown.

Aims: This study aimed to investigate the associations of BP and RHR with all-cause mortality in patients with TR.

Methods: A total of 2,013 patients with moderate or severe TR underwent echocardiography and BP measurement.

Effects of Residential Environment and Lifestyle on Atopic Eczema Among Preschool Children in Shenzhen, China.

Eczema, one of the most prevalent inflammatory skin diseases among children, is potentially influenced by genetic, environmental and social factors. However, few studies have investigated the effect of residential environment and lifestyle on childhood eczema. Therefore, this study conducted a cross-sectional study based on 2,781 preschool children in Shenzhen, China, during 2015-2016.

Prognostic value of modified model for end-stage liver disease scores in patients with significant tricuspid regurgitation.

Aims: Tricuspid regurgitation (TR) may cause damage to liver and kidney function. The Model for End-Stage Liver Disease excluding international normalized ratio (MELD-XI) and the model with albumin replacing international normalized ratio (MELD-Albumin) scores, which include both liver and kidney function indexes, may predict mortality in patients with TR. The study aimed to analyse the prognostic value of MELD-XI and MELD-Albumin scores in patients with significant TR.

Prognostic Impact of Left Ventricular Ejection Fraction in Patients With Moderate Aortic Regurgitation: Potential Implications for Treatment Decision-Making.

Background: The prognostic impact and optimal treatment of left ventricular systolic dysfunction in patients with moderate aortic regurgitation (AR) remain unknown. We aimed to assess the prognostic value of left ventricular ejection fraction (LVEF) in patients with moderate AR and explore the potential benefits of aortic valve intervention (AVI).

Local dispersion characteristics of dust in large open-air piles under the action of one-way wind.

A large amount of dust particles produced by the wind in an open-air pile is one of the important reasons for air pollution. Studying the law of dust diffusion in local areas is of great significance for the atmospheric particulate control. In this study, a pile of sodium carbonate in a large open-air pile in Weifang, China, is regarded as the research object.

Graphitic Carbon Nitride (g-C3N4) Nanosheets/Graphene Composites: In Situ Synthesis and Enhanced Photocatalytic Performance.

A facile In Situ growth method was presented here for the preparation of graphitic carbon nitride (g-C3N4)/graphene composites, in which the direct growth and deposition of g-C3N4 nanosheets from organic N and C sources on the graphene surfaces was achieved to form the 3D contacted structure. The resulting 3D architecture possessed multilevel porous structure and efficient g-C3N4/graphene interfaces, which facilitated the fast electron transfer at the interfaces. Photoluminescence spectra showed that the recombination of photogenerated electrons and holes in the g-C3N4/graphene composites was greatly inhibited by the introduction of graphene, indicating the more efficient separation of electrons and hole in the g-C3N4/graphene composites than in pure g-C3N4.
