Article Abstract
Background: The benefits of pulmonary rehabilitation (PR) for patients with idiopathic pulmonary fibrosis (IPF) have been limited to improving dyspnea, exercise capacity, and quality of life (QoL). This study aimed to assess the current status of PR and its effect on prognosis.
Methods: The Nationwide Korean Health Insurance Review and Assessment Service (HIRA) database was used in this study. Annual PR implementation rate since 2016 following its coverage in the health insurance was analyzed. IPF cases were defined using the International Classification of Diseases 10 Revision (ICD-10) codes and rare intractable diseases (RID) codes. Risk of acute exacerbation (AE) and mortality of IPF patients with or without PR were analyzed.
Results: Of the 4,228 patients with IPF, only 205 (4.85%) received PR. Patients in the PR group were more frequently treated with pirfenidone and systemic steroids than non-PR group. In patients treated with steroids, mortality risk increased regardless of PR application, with hazard ratio (HR) of 1.63 [95% confidence interval (CI): 1.26-2.10, P<0.001] in the PR group and 1.38 (95% CI: 1.21-1.57, P<0.001) in the non-PR group, compared to those not treated with steroids. Additionally, PR did not significant affect mortality risk in patients not receiving steroids (HR, 1.49, 95% CI: 0.87-2.54, P=0.15). Similar patterns were seen for the risk of AE.
Conclusions: PR was applied in only a minority of patients with IPF. It did not succeed in reducing the risk of AE or mortality. A prospective study targeting early-stage patients is needed to evaluate the impact of PR considering the progressive nature of IPF disease itself.

It is helpful for diagnostic purposes to improve our current knowledge of gut development and serum biochemistry in young piglets. This study investigated serum biochemistry, and gut site-specific patterns of short-chain fatty acids (SCFA) and expression of genes related to barrier function, innate immune response, antioxidative status and sensing of fatty and bile acids in suckling and newly weaned piglets. The experiment consisted of two replicate batches with 10 litters each.

Purpose Of Review: Plasma metagenomic next-generation sequencing (mNGS) enables detection of microbial cell-free deoxyribonucleic acid (mcfDNA) in blood without the need for culture or organism-specific primers. Here, we review clinical performance, methodological variability, and real-world application of plasma mNGS for infectious disease diagnosis in immunocompromised hosts (ICHs).
Recent Findings: Plasma mNGS has rapidly gained attention as a novel diagnostic tool for infections in ICHs, offering broad-range pathogen detection from a noninvasive blood sample.
Updates on the Chemical and Enzymatic Treatments of Poly(styrene-co-divinylbenzene) and Poly(methyl methacrylate) Particles: A Bibliometric and An Experimental Approach.

Polymer particles, including synthetic polymers such as poly(methyl methacrylate) (PMMA) and poly(styrene-co-divinylbenzene) (P(S-co-DVB)) beads, have been widely used as enzymatic supports and drug carriers. In this sense, it is important to understand the stabilization or degradation of such polymer matrices under specific chemical and enzymatic media. For this reason, the present work aims to evaluate the current status and prospects of treatments of PMMA and P(S-co-DVB) particles intended for biotechnological and biomedical applications under basic, acidic, and enzymatic environments.

Introduction: Cigarette smoking negatively affects lung cancer prognosis. Incorporating smoking history into stage-stratified survival analyses may improve prognostication.
Methods: Using the International Association for the Study of Lung Cancer ninth edition NSCLC database, we evaluated the association between smoking status at diagnosis and overall survival (OS) using Kaplan-Meier plots and multivariate Cox proportional hazard regression models adjusted for age, region, sex, histologic type, performance status, and TNM stage.

Objectives: This study aimed to investigate the potential contribution of subtle peripheral auditory dysfunction to listening difficulties (LiD) using a threshold-equalizing noise (TEN) test and distortion-product otoacoustic emissions (DPOAE). We hypothesized that a subset of patients with LiD have undetectable peripheral auditory dysfunction.
Design: This case-control study included 61 patients (12 to 53 years old; male/female, 18/43) in the LiD group and 22 volunteers (12 to 59 years old; male/female, 10/12) in the control group.
