AI Article Synopsis
- - The study aimed to investigate how working hours and physical activity in the workplace relate to the development of coronary heart disease (CHD) in a Chinese population.
- - Researchers surveyed 595 participants (both with and without CHD) aged 24 to 65, using questionnaires and logistic regression to analyze data collected between December 2015 and October 2016.
- - Findings revealed that long working hours (≥55 hours/week) and sedentary behavior at work significantly raised the risk of CHD, even when leisure time physical activity was considered.
Article Abstract
Objective: To explore the association of working hours and occupational physical activity (OPA) with the occurrence of coronary heart disease (CHD) in a Chinese population.
Methods: A total of 595 participants (354 and 241 patients with and without CHD, respectively) aged between 24 and 65 were enrolled in our study, which was conducted at the First Affiliated Hospital of Nanjing Medical University between December 2015 and October 2016. Participant characteristics were collected from face-to-face questionnaires, and logistic regression analysis was conducted to examine the association of working hours and OPA with the occurrence of CHD.
Results: Compared with non-employed people, long working hours (especially ≥55 hours/week) contributed to the occurrence of CHD (adjusted odds ratio[OR] = 2.213, 95% confidence interval [CI]: 1.125, 4.355, P = 0.021) after multivariate adjustment in the Chinese population. With the extension of worktime, the CHD risk increased (P for the dose-response trend = 0.022). Meanwhile, even after adjusting for engagement in physical activity during leisure time, sedentary behavior at work had an adverse effect on CHD risk (adjusted OR = 2.794, 95%CI: 1.526, 5.115, P = 0.001), and a linear relationship was also found between OPA and CHD (P for the trend = 0.005).
Conclusions: Long working hours and sedentary behavior at work are associated with a high risk of CHD. In addition, prolonged working hours in sedentary occupations increases the risk of CHD, independent of engagement in leisure time physical activity.

Heart defects are the second most common congenital anomaly in babies born in the UK and standards state families should have access to a children's cardiac nurse specialist telephone advice service. However, there is little published information to describe the nature of calls and the workload associated with telephone support. We conducted a prospective service evaluation of telephone calls received at one UK specialist children's cardiac surgical center from parents/carers (April-June 2019).

Background: Sleep deprivation leads to an increase in oxidative stress and activation of inflammatory response and both could increase the production and accumulation of toxic beta-amyloid in the hippocampus which is considered one of the molecular drivers of Alzheimer's pathogenesis and progression. Despite these findings, obtaining sleep is still challenging in our modern society that values work around the clock. Omega-3 fatty acids represents an active biological agent with vital antioxidant and anti-inflammatory activities that could protect memory in the face of insufficient sleep.

Background: Drug discovery efforts in neurological diseases, such as Alzheimer's disease (AD), have had particularly poor outcomes due to the lack of models that capture the cerebral vasculature. There is an unmet need to develop models that capture the physiological challenge of overcoming the blood-brain barrier (BBB) and impacts of blood flow-induced shear stress. In this work, we use a microfluidic platform to model the cerebral vasculature in familial AD (fAD) using patient-derived brain endothelial-like cells (BECs) and neurons.

Background: Previous studies have found that mechanistic target of rapamycin complex 1 (mTORC1) activity is significantly increased in Alzheimer's disease (AD) patients and mouse models of AD. Additionally, inhibition of mTORC1 with systemic rapamycin treatment ameliorates AD-like phenotypes in several AD mouse models. However, the specific contribution of neuronal mTORC1 signaling in driving AD phenotypes has not yet been explored.
