Identification of Ala2Thr mutation in insulin gene from a Chinese MODY10 family.

Mol Cell Biochem

July 2020

Shanghai Diabetes Institute, Department of Endocrinology & Metabolism, Shanghai Key Clinical Center for Metabolic Disease, Shanghai Key Laboratory of Diabetes Mellitus, Shanghai Jiaotong University Affiliated Sixth People's Hospital, 600 Yishan Road, Shanghai, 200233, China.

More than 80% of maturity-onset diabetes of the young (MODY) in Chinese is genetically unexplained. To investigate whether the insulin gene (INS) mutation is responsible for some Chinese MODY, we screened INS mutations causing MODY10 in MODY pedigrees and explored the potential pathogenic mechanisms. INS mutations were screened in 56 MODY familial probands.

Dilated cardiomyopathy (DCM) is an important cause of heart failure and the leading indication for heart transplantation. Many rare genetic variants have been associated with DCM, but common variant studies of the disease have yielded few associated loci. As structural changes in the heart are a defining feature of DCM, we report a genome-wide association study of cardiac magnetic resonance imaging (MRI)-derived left ventricular measurements in 36,041 UK Biobank participants, with replication in 2184 participants from the Multi-Ethnic Study of Atherosclerosis.

Article Synopsis
  • Educational attainment serves as a proxy for socioeconomic status (SES), which is linked to increased risks of hypertension and high blood pressure (BP).
  • The study focused on exploring genetic factors influencing BP by examining how education levels (specifically "Some College" and "Graduated College") interact with genetics, using large-scale multi-ancestry analyses to identify both known and new genetic loci associated with BP.
  • From two phases of research involving over 400,000 participants, the study discovered 84 previously recognized and 18 new genetic loci related to BP, particularly noting the importance of SES and educational attainment in understanding genetic influences on BP regulation.

Heme metabolism genes Downregulated in COPD Cachexia.

Respir Res

May 2020

Department of Epidemiology, School of Public Health, University of Alabama at Birmingham, Birmingham, AL, USA.

Introduction: Cachexia contributes to increased mortality and reduced quality of life in Chronic Obstructive Pulmonary Disease (COPD) and may be associated with underlying gene expression changes. Our goal was to identify differential gene expression signatures associated with COPD cachexia in current and former smokers.

Methods: We analyzed whole-blood gene expression data from participants with COPD in a discovery cohort (COPDGene, N = 400) and assessed replication (ECLIPSE, N = 114).

Methicillin-resistant (MRSA) poses significant therapeutic challenges related to its frequency in clinical infections, innate virulence properties, and propensity for multiantibiotic resistance. MRSA is among the most common causes of endovascular infections, including infective endocarditis (IE). Our objective was to employ transthoracic echocardiography (TTE) to evaluate the effect of exebacase, a novel direct lytic agent, in experimental aortic valve MRSA IE.

Background And Aims: We sought to understand the risk factor correlates of very early coronary artery calcium (CAC), and the potential investigational value of CAC phenotyping in adults aged 20-30 years.

Methods: We studied all participants aged 20-30 years at baseline (N = 373) in the Coronary Artery Calcium Consortium, a large multi-center cohort study of patients aged 18 years or older without known atherosclerotic cardiovascular disease (ASCVD) at baseline, referred for CAC scoring for clinical risk stratification. We described the prevalence of CAC in men and women, the frequency of risk factors by the presence of CAC (CAC = 0 vs CAC >0), and assessed the association between traditional non-demographic CVD risk factors (hypertension, hyperlipidemia, smoking, family history of CHD, and diabetes) and prevalent CAC, using age- and sex-adjusted logistic regression models.

The Unique Clinical Phenotype and Exercise Adaptation of Fontan Patients With Normal Exercise Capacity.

Can J Cardiol

September 2020

Department of Pediatrics, University of Cincinnati College of Medicine, Cincinnati, Ohio, USA; The Heart Institute, Cincinnati Children's Hospital Medical Center, Cincinnati, Ohio, USA.

Background: Exercise limitation is almost universal among Fontan patients. Identifying unique clinical features in the small fraction of Fontan patients with normal exercise capacity (high-capacity Fontan [HCF]) provides potential to inform clinical strategies for those with low exercise capacity (usual Fontan).

Methods: We performed a retrospective chart review of all patients with single-ventricle physiology palliated with a Fontan operation who underwent incremental cardiopulmonary exercise testing at Cincinnati Children's Hospital Medical Center from 2013 to 2018.

Background: Coronary artery calcium (CAC) is a well-established quantifiable risk factor for cardiovascular disease (CVD). We examined the association of anger, hostility, anxiety, and depression with the development and progression of CAC.

Methods: We studied the association of these psychosocial traits with CAC among participants in the Multi-Ethnic Study of Atherosclerosis (MESA).

Background: Although inhaled therapy reduces exacerbations among patients with COPD, the effectiveness of providing inhaled treatment per risk stratification models remains unclear.

Research Question: Are inhaled regimens that align with the 2017 Global Initiative for Chronic Obstructive Lung Disease (GOLD) strategy associated with clinically important outcomes?

Study Design And Methods: We conducted secondary analyses of Long-term Oxygen Treatment Trial (LOTT) data. The trial enrolled patients with COPD with moderate resting or exertional hypoxemia between 2009 and 2015.

Background And Aims: Non-alcoholic fatty liver disease (NAFLD) is associated with inflammation and atherogenic lipoprotein abnormalities. Previous studies suggest an association of fibroblast growth factor 21 (FGF21) with NAFLD. Therefore, we assessed the association of circulating FGF21 levels with inflammatory markers, lipoprotein profile and NAFLD in the Multi-Ethnic Study of Atherosclerosis (MESA).

Article Synopsis
  • Aortic stenosis (AS) currently has no approved medical treatment, prompting researchers to explore genetic factors and pathways associated with the condition to identify potential drug targets.
  • A genome-wide association study analyzed data from 44,703 participants, including 3,469 diagnosed with AS, along with additional replication cohorts, revealing significant genetic associations and links to fatty acid levels in the blood.
  • The study identified a notable genetic variant (rs174547) that was correlated with a reduced likelihood of developing AS and found connections between blood fatty acid ratios and aortic valve calcium presence, highlighting potential areas for future research and treatment strategies.*

Objectives: The Women's Health Initiative (WHI) randomized trial identified age differences in the benefit-risk profile of estrogen-alone (ET) use. The impact of WHI trial on disease-associated medical expenditures attributable to subsequent decreased ET utilization has, however, not been measured. Therefore, the objective of this analysis was to quantify the age-specific disease-associated medical expenditures attributable to reduced ET utilization after the WHI Hormone Therapy (HT) trials.

Objective: Low HDL cholesterol (HDL-C) is common in people living with HIV infection, which is associated with inflammation, and correlates with greater cardiovascular disease (CVD) risk. Particles of HDL are HDL subfractions, and in some general population studies, higher small HDL particle number (HDL-P) has been associated with lower CVD risk. The objective of this study was to determine whether HIV serostatus and systemic inflammation were associated with small HDL-P in the Multicenter AIDS Cohort Study (MACS).

Article Synopsis
  • Nonalcoholic fatty liver disease (NAFLD) is a significant liver disease concern globally, and the study aimed to explore if elevated levels of sex hormone-binding globulin (SHBG) could offer protection against NAFLD in men, particularly those with or without HIV.
  • The research involved 530 men from the Multicenter AIDS Cohort Study, where NAFLD was assessed through CT scans while examining various hormones and metabolic factors in blood samples.
  • Results showed that higher SHBG levels were linked to a lower risk of NAFLD, particularly among HIV-positive men, indicating that SHBG might play a protective role against the disease and warrants further investigation.
