Predictors of Low Cardiac Output Syndrome in Infants After Open-Heart Surgery.

Objective: To evaluate the predictors of low cardiac output syndrome (LCOS) in infants with congenital heart disease (CHD) after cardiopulmonary bypass (CPB).

Study Design: A total of 217 infants were enrolled and classified according to whether they developed LCOS after cardiac surgery. Each infant's preoperative and intraoperative clinical variables were collected.

Modelling homosexual and heterosexual transmissions of hepatitis B virus in China.

Studies have shown that sexual transmission, both heterosexually and homosexually, is one of the main ways of HBV infection. Based on this fact, we propose a mathematical model to study the sexual transmission of HBV among adults by classifying adults into men and women and considering both same-sex and opposite-sex transmissions of HBV in adults. Firstly, we calculate the basic reproduction number and the disease-free equilibrium point .

Preoperative thyroid hormone levels predict ICU mortality after cardiopulmonary bypass in congenital heart disease patients younger than 3 months old.

Background: We aimed to study the effectiveness of preoperative thyroid hormone levels in predicting intensive care unit (ICU) mortality after cardiopulmonary bypass (CPB) in infants with congenital heart disease (CHD).

Methods: We retrospectively reviewed and analyzed data from 133 patients younger than 3 months old who underwent cardiac surgery with CPB from June 2017 to November 2019. ICU mortality prediction was assessed by multivariate binary logistic regression analysis and area under the curve (AUC) analysis.

Cytochrome P450 Epoxygenase 2J2 Protects Against Lung Ischemia/Reperfusion Injury by Activating the P13K/Akt/GSK-3-β/NF-kB Signaling Pathway During Deep Hypothermic Low Flow in Mice.

Background: Cytochrome P450 epoxygenase 2J2 (CYP2J2) metabolizes arachidonic acid to epoxyeicosatrienoic acids, which exert anti-inflammatory effects and alleviate oxidative stress in the cardiovascular system. Our previous work revealed that CYP2J2 is expressed in pulmonary artery endothelial cells. It was therefore hypothesized that CYP2J2 overexpression may prevent lung ischemia/reperfusion injury (LIRI) in 3-week-old C57BL/6 mice during deep hypothermic low flow (DHLF).

Effects of Exercise Training in Postoperative Patients With Congenital Heart Disease: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Background The purpose of this meta-analysis is to assess the effects of exercise training on quality of life, specific biomarkers, exercise capacity, and vascular function in congenital heart disease (CHD) subjects after surgery. Methods and Results We searched the Cochrane Central Register of Controlled Trials, MEDLINE, and EMBASE from the date of the inception of the database through April 2019. Altogether, 1161 records were identified in the literature search.

Associations between mercury exposure and the risk of nonalcoholic fatty liver disease (NAFLD) in US adolescents.

Little is known regarding the effects of environmental mercury (Hg) exposure on liver dysfunction in adolescents. We aimed to explore the association between Hg exposure and the risk of nonalcoholic fatty liver disease (NAFLD) in the adolescent population. The cross-sectional associations between blood Hg concentrations and serum alanine aminotransferase (ALT) levels, a surrogate for suspected NAFLD, were evaluated using data from adolescents (aged 12-17 years old) who participated in the National Health and Nutrition Examination Survey (NHANES), 1999-2014.

Association between perfluoroalkyl substance concentrations and blood pressure in adolescents.

The effects of exposure to some environmental chemicals on blood pressure have been determined, but the association between non-occupational exposure to perfluoroalkyl substances (PFASs) and blood pressure in adolescents remains unknown. The association between blood pressure and PFAS concentrations was studied by analysing data from 2251 participants filtered from the population enrolled in the National Health and Nutrition Examination Survey (NHANES) from 2003 to 2012. After adjusting for age, sex, race, BMI, cotinine level, dietary intake of calcium, caloric intake, sodium consumption, potassium consumption and sampling year, we estimated the coefficients (betas) and 95% confidence intervals (CIs) for the relationship between PFAS concentrations and blood pressure with multiple linear regression models.

Serum 25-hydroxyvitamin D is associated with obesity and metabolic parameters in US children.

Objective: To explore the relationships of serum 25-hydroxyvitamin D (25(OH)D) with obesity and metabolic parameters in US children.

Design: Cross-sectional analysis. We evaluated the associations between serum 25(OH)D and multiple measurements of adiposity, serum lipid concentrations, fasting glucose and insulin resistance in children aged 6-18 years with adjustments for multiple covariates.

Associations of trace elements in blood with the risk of isolated ventricular septum defects and abnormal cardiac structure in children.

This study sought to determine correlations between the presence of isolated ventricular septum defects (VSDs) and blood levels of trace elements. A total of 144 patients with VSDs and 144 controls were recruited for cross-sectional assessment of trace elements and examination of cardiac structures in the Jiangsu and Anhui provinces between 2016 and 2018. Logistic regression was performed to explore the relationships between VSDs and trace elements.

Modeling the Transmission Dynamics of Rabies for Dog, Chinese Ferret Badger and Human Interactions in Zhejiang Province, China.

Human rabies is one of the major public health problems in China with an average of 1977 cases per year. It is estimated that 95% of these human rabies cases are due to dog bites. In recent years, the number of wildlife-associated human rabies cases has increased, particularly in the southeast and northeast regions of mainland China.

Associations between total mercury and methyl mercury exposure and cardiovascular risk factors in US adolescents.

Low levels of chronic heavy metal exposure are associated with a range of adverse health effects. However, whether total blood mercury (Hg) and methyl mercury (MeHg) exposure affect risk factors for cardiovascular disease (CVD) in adolescents remains unclear. The associations between CVD risk factors and total blood Hg and MeHg in adolescents were evaluated using data from the National Health and Nutrition Examination Survey (NHANES), 2011-2012.

Associations between lead concentrations and cardiovascular risk factors in U.S. adolescents.

Little is known regarding the effects of environmental lead exposure on cardiovascular risk factors in the adolescent population. We studied 11,662 subjects included in the National Health and Nutrition Examination Survey (NHANES) 1999-2012. Blood lead levels were analysed for their association with cardiovascular risk factors (CVRF).
