Effects of PM exposure and air temperature on risk of cardiovascular disease: evidence from a prospective cohort study.

Background And Aims: Evidence from extensive cohort studies about the individual and combined associations of air pollution and air temperature with cardiovascular disease (CVD) morbidity is limited. This study aimed to examine the long-term effects of PM exposure and air temperature on CVD based on a cohort study of middle-aged and older populations in China.

Methods: A total of 9,316 non-CVD adults (≥40 years old) who joined the China Health and Retirement Longitudinal Study between 2011 and 2018 were included in our analysis.

Comparison of outcomes following prepectoral and subpectoral implants for breast reconstruction in patients with breast cancer.

Background: In recent years, different approaches to implant-based breast reconstruction have increasingly become an important option to meet both the treatment and postoperative aesthetic needs of breast cancer patients. This study selected two commonly used techniques for the prepectoral approach: single-incision, gas-inflated endoscopic prepectoral breast reconstruction (SIE-BR) and open prepectoral implant-based breast reconstruction (C-BR), as well as a commonly used technique for the subpectoral approach: open subpectoral implant-based breast reconstruction (SI-BR). By comparing the clinical efficacy and aesthetic outcomes of these three techniques in the treatment of breast cancer patients, this study aims to summarize the advantages of the prepectoral approach.

Using resting-state functional magnetic resonance imaging and contrastive learning to explore changes in the Parkinson's disease brain network and correlations with gait impairment.

Background: There are currently no deep learning models applying resting-state functional magnetic resonance imaging (rs-fMRI) data to distinguish patients with Parkinson's disease (PD) and healthy controls (HCs). Moreover, no study has correlated objective gait parameters with brain network alterations in patients with PD. We propose BrainNetCNN + CL, applying a convolutional neural network (CNN) and joint contrastive learning (CL) method to brain network analysis to classify patients with PD and HCs, and compare their performance with classical classification methods.

IBI310 plus sintilimab vs. placebo plus sintilimab in recurrent/metastatic cervical cancer: A double-blind, randomized controlled trial.

Background: It remains unclear whether adding CTLA-4 blockade to PD-1/PD-L1 blockade improves clinical outcomes in cervical cancer (CC).

Methods: In this randomized, double-blind, placebo-controlled, phase 2 study (ClinicalTrials.gov: NCT04590599), patients with recurrent/metastatic CC (R/M CC) who experienced disease progression after or during platinum-based chemotherapy were enrolled from 37 centers across China and randomly assigned (1:1), stratified by PD-L1 expression and prior treatment lines, to receive either IBI310 plus sintilimab or placebo plus sintilimab intravenously every 3 weeks for 12 weeks, followed by sintilimab alone.
