Article Abstract
There is a paucity of data reporting the positive and negative predictive values (PPV, NPV) of acute declines in lung function on chronic lung allograft dysfunction (CLAD). We sought to define the predictive ability of single or repeated forced expiratory volume in the first second (FEV) declines for at least 3 weeks on the development of CLAD or death by 1-year. We analyzed 340 subjects with at least 3 years of follow-up data from two lung transplant centers. A single ≥10% FEV decline had a PPV of 35% and NPV of 63%, and a repeated ≥10% FEV decline for at least 3 weeks had a PPV of 44% and NPV of 65%. Notably, the proportion of individuals with incipient CLAD at the time of a single or repeated ≥20% FEV1 decline was 50% and 71%, respectively. These estimates could inform the development of acute lung allograft dysfunction FEV thresholds as enrollment criteria or surrogate outcome measures.

Background: Microfocused ultrasound (MFU) is a non-invasive technique used for facial rejuvenation, yet there is limited quantitative data on its long-term effects. This study aimed to evaluate the long-term efficacy and safety of MFU for facial rejuvenation. We utilized standardized photography along with advanced skin assessment technologies to analyze the impact of MFU on facial morphology, skin function, and patient satisfaction over a 12-month period.

Nosocomial infections remain a major healthcare challenge, underlining the demand for antimicrobial technologies. Far UV-C (200-235 nm) has emerged as a safer alternative to traditional 254 nm UV-C for microbial reduction on skin and wounds but also in occupied spaces due to its strong germicidal properties and minimal skin penetration. However, studies on humans remain limited.

Housing insecurity is a key social determinant of a wide range of health outcomes, subject to large racial inequities, and with a likely sensitive period in childhood. Housing insecurity can manifest in multiple ways and change over time, but previous studies have primarily focused on single dimensions or a single time point. This study examines cumulative exposure to multiple forms of housing insecurity from birth to adolescence, overall, and by race in large US cities.

Background: The dynamic progression of gray matter (GM) microstructural alterations following radiotherapy (RT) in patients, and the relationship between these microstructural abnormalities and cortical morphometric changes remains unclear.
Purpose: To longitudinally characterize RT-related GM microstructural changes and assess their potential causal links with classic morphometric alterations in patients with nasopharyngeal carcinoma (NPC).
Study Type: Prospective, longitudinal.
