Confocal Raman Microscopy for Measuring In Situ Temperature-Dependent Structural Changes in Poly(Ethylene Oxide) Thin Films.

Crystallization from the melt is a critical process governing the properties of semi-crystalline polymeric materials. While structural analyses of melting and crystallization transitions in bulk polymers have been widely reported, in contrast, those in thin polymer films on solid supports have been underexplored. Herein, in situ Raman microscopy and self-modeling curve resolution (SMCR) analysis are applied to investigate the temperature-dependent structural changes in poly(ethylene oxide) (PEO) films during melting and crystallization phase transitions.

Performance of Risk-Stratification Scores for Patients With Pulmonary Arterial Hypertension in a Multi-Ethnic Asian Population.

Guidelines recommend risk stratification of pulmonary arterial hypertension (PAH) patients to guide management. There are currently several risk stratification scores available, which have largely been validated in various pulmonary hypertension registries in the West but not in Asia. We aim to study the performance of these different risk scores in PAH patients from a multi-ethnic Asian population.

Radiotherapy-Induced Stevens-Johnson Syndrome/ Toxic Epidermal Necrolysis in an Adolescent Girl With Diffuse Glioma of the Pons.

Radiotherapy is a rare cause of Stevens-Johnson syndrome (SJS)/ toxic epidermal necrolysis (TEN), especially in the pediatric age group. Most of the reported cases were concomitantly started on anti-epileptic drugs. Herein, we present a case of radiotherapy induced SJS/TEN in an adolescent girl in the absence of anti-epileptic drug use.

Patient Characteristics, Management, and Outcomes of Adult Asthma in a Singapore Population: Data from the SDG-CARE Asthma Registry.

Purpose: Patients with asthma in Singapore often have complex patient journeys, with diagnosis and management across various primary and speciality care settings. Real-world population health data is needed to identify care gaps and inform policies.

Patients And Methods: This retrospective, longitudinal cohort study assessed real-world data from adults (aged ≥18 years) with asthma in the SingHealth Chronic Obstructive Pulmonary Disease and Asthma Data Mart, an integrated database of electronic medical records of patients who attended primary and/or speciality care clinics in the SingHealth Regional Health System 01/01/2015-12/31/2020.
