Air pollution is a significant public health issue that impacts lung health, particularly in vulnerable populations such as children, the elderly, and individuals with pre-existing respiratory conditions. Both natural and anthropogenic sources of air pollution give rise to a variety of toxic compounds, including particulate matter (PM), ozone (O₃), sulfur dioxide (SO₂), nitrogen dioxide (NO₂), carbon monoxide (CO), and polycyclic aromatic hydrocarbons (PAHs). Exposure to these pollutants is strongly associated with the development and exacerbation of respiratory diseases, including asthma, chronic obstructive pulmonary disease (COPD), lung cancer, and idiopathic pulmonary fibrosis (IPF). Notably, early life exposure to pollutants such as …

Psychology Faculty Articles and Research

Anhedonia is increasingly recognized as a transdiagnostic risk factor for psychopathology. New evidence demonstrates that anhedonia is present in infancy and early childhood. Structural variability in striatal regions involved in reward processing and pleasure seeking is concurrently linked to anhedonia, yet few studies have examined whether striatal differences presage anhedonia, and none have examined prospective associations before middle childhood. The present study examined whether neuroanatomical markers that confer risk for anhedonia can be detected as early as the neonatal period. Specifically, we tested whether the volume of striatal regions in neonates predicted the emergence of infant anhedonic behaviors at six …

Optimizing Initial Screening For Colorectal Cancer Detection With Adherence Behavior, Sarah Yini Gao, Yan He, Ruijie Zhang, Zhichao Zheng, Shao Wei Lam Lam, Emile Tan

Research Collection Lee Kong Chian School Of Business

Background: Two-stage screening programs are widely adopted for early colorectal cancer (CRC) detection, where individuals receiving positive outcomes in the first-stage (initial) test are recommended to undergo a second-stage test (colonoscopy) for further diagnosis. Methods: We study the initial test design—the selection of cutoffs for reporting test outcomes—to balance the trade-off between screening effectiveness (i.e., CRC and polyp detection) and efficiency (i.e., colonoscopy costs), incorporating the fact that not all individuals follow up with a colonoscopy after receiving positive outcomes. We integrate the Bayesian persuasion framework with information avoidance to model this problem and apply it to Singapore's CRC screening …

Low Prevalence Of Helminth Infection In Ugandan Children Hospitalized With Severe Malaria, Drew Capone, Nuzrath Jahan, Ruth Namazzi, Robert Opoka, Chandy John

Paediatrics and Child Health, East Africa

Co-infection by intestinal helminths and Plasmodium spp. may be common in endemic communities. In 2003, Uganda instituted a national deworming program, with anti-helminth medication provided twice annually to children 6 months to 5 years of age, but few follow-up studies have been conducted. Several studies have identified a relationship between helminth infection, Plasmodium spp. infection and malaria severity. However, the relationship is not well defined, and results are inconclusive. We analyzed 177 stool samples from a cohort of children with severe malaria enrolled in two hospitals in Uganda from 2014–2017. All children were 6 months to 48 months of age …
