Environ Health (Wash)

December 2024

Department of Epidemiology and Biostatistics, School of Public Health, Peking University, Beijing 100191, China.

The adverse effect of ambient PM exposure on very early pregnancy (VEP) remains controversial among epidemiological studies but is supported by toxicological evidence. We adopted a multicenter retrospective cohort of 141,040 cycles to evaluate the effect of PM exposure on the VEP using the fertilization and embryo transfer platform and high-resolution PM data in China. We first investigated the association between PM exposure 1 week before and 1 week after the embryo transfer date and VEP.

It is now understood that brain metastases do not occur randomly but have distinct spatial patterns depending on the origin of the cancer. According to the "seed and soil" hypothesis, the final colonization of metastatic cells is the result of their adaptation to the altered environment. To investigate the most favorable microenvironment for brain metastasis, we analyzed neuroimaging data from 177 patients with breast cancer brain metastasis and 548 patients with lung cancer brain metastasis to create a replicable probabilistic map of metastatic locations.

Cognitive and cortical network alterations in pediatric temporal lobe space-occupying lesions: an fMRI study.

Front Hum Neurosci

December 2024

Department of Pediatric Neurosurgery, Beijing Tiantan Hospital, Capital Medical University, Beijing, China.

Background: Temporal lobe mass lesions are the most common intracranial space-occupying lesions in children, among various brain lobes. The temporal lobe is critically involved in higher cognitive functions, and surgical interventions often risk causing damage to these functions. If necessary interventions and prehabilitation can be conducted preoperatively, it might be possible to achieve a larger extent of lesion resection with minimal cognitive impairment.

This study aimed to identify a cognitive function network that is responsive to cognitive changes during cognitive tasks and also sensitive to PSCI. To explore the network, we analyzed resting-state fMRI data from 20 PSCI patients and task-state fMRI data from 100 unrelated healthy young adults using functional connectivity analysis.
