Connective tissue disease (CTD), comprising a range of autoimmune disorders, is often accompanied by lung involvement, which can lead to life-threatening complications. The primary types of CTDs that manifest as interstitial lung disease (ILD) include rheumatoid arthritis, systemic sclerosis, Sjögren’s syndrome, mixed CTD, idiopathic inflammatory myopathies, and systemic lupus erythematosus. CTD-ILD presents a significant challenge in clinical diagnosis and management due to its heterogeneous nature and variable prognosis. Early diagnosis through clinical, serological, and radiographic assessments is crucial for distinguishing CTD-ILD from idiopathic forms and for implementing appropriate therapeutic strategies. Hence, we have reviewed the multiple clinical manifestations and diagnostic approaches for each type of CTD-ILD, acknowledging the diversity and complexity of the disease. The importance of a multidisciplinary approach in optimizing the management of CTD-ILD is emphasized by recent therapeutic advancements, which include immunosuppressive agents, antifibrotic therapies, and newer biological agents targeting specific pathways involved in the pathogenesis. Therapeutic strategies should be customized according to the type of CTD, the extent of lung involvement, and the presence of extrapulmonary manifestations. Additionally, we aimed to provide clinical guidance, including therapeutic recommendations, for the effective management of CTD-ILD, based on patient, intervention, comparison, outcome (PICO) analysis.

Purpose:
To evaluate the characteristics, anatomical success rate, and factors that may affect the anatomical success of rhegmatogenous retinal detachment in patients in their 20s.
Methods:
We retrospectively analyzed the medical records of patients aged 20-29 years who underwent surgery for rhegmatogenous retinal detachment from January 2018 to December 2022. We examined factors such as sex, age, duration of illness, preoperative best corrected visual acuity, presence of underlying diseases, proliferative vitreoretinopathy, lattice degeneration, macular involvement, extent of retinal detachment at diagnosis, axial length, and myopia level to explore their impact on surgical outcomes.
Results:
The study included 122 eyes. The mean age was 23.81 ± 2.82 years, and the average sphere power was -5.80 ± 3.71 diopters (D). The percentage of eyes with a refraction of ≤ -6.0 D came to 44.3% (54/122), and with ≤ -4.0 D it amounted to 72.1% (88/122). The average logarithm of the minimum angle of resolution (logMAR) best corrected visual acuity improved significantly from 0.52 ± 0.68 before surgery to 0.28 ± 0.45 after surgery. The primary surgical success rates were 92.0% for scleral buckling, 88.9% for vitrectomy, and 92.3% for combined scleral buckling and vitrectomy, with no significant factors related to anatomical success identified.
Conclusions
There was a high prevalence of moderate to severe myopia among patients in their 20s with rhegmatogenous retinal detachment. However, no statistically significant correlation was found between the degree of myopia and anatomical success. Both functional and anatomical outcomes were generally favorable in these patients.

Annals of Surgical Treatment and Research 2025;109(2):89-97
Purpose:
The selection of primary tumor resection (PTR) vs. self-expanding metallic stents (SEMS) in obstructive unresectable stage IV colorectal cancer (CRC) is critical, profoundly impacting patient outcome. This study evaluates the influence of PTR and SEMS on overall survival (OS) in conjunction with chemotherapy.
Methods:
The analysis included 137 patients with obstructive, unresectable stage IV CRC who underwent PTR or attempted SEMS placement. The primary objective was to assess the OS of patients, specifically examining how PTR and SEMS interventions influence these survival outcomes.
Results:
In a cohort of 137 patients with obstructive, unresectable stage IV CRC, 30 initially opted for PTR, while stent placement was attempted in 107 cases. Following 14 stent failures, which resulted in 8 diversions and 6 additional PTR interventions, exclusions due to elective surgeries led to a final analysis of 36 PTR and 72 SEMS cases. Cox regression analysis identified no significant survival advantage between PTR and SEMS interventions (hazard ratio [HR], 0.848; 95% confidence interval [CI], 0.555–1.298; P = 0.449). Critical findings highlighted that the absence of chemotherapy markedly reduced survival prospects (HR, 1.963; 95% CI, 1.200–3.211; P = 0.007). These insights were substantiated through propensity score matching.
Conclusions
The comparative analysis reveals that neither PTR nor SEMS offers a definitive survival advantage in managing obstructive, unresectable stage IV CRC. However, the necessity for subsequent invasive interventions is notably lower in the PTR group.
10.Clinical Applications of Speckle-Tracking Echocardiography in Heart Failure: From Diagnosis to Prognostication
International Journal of Heart Failure 2025;7(4):201-215
Speckle-tracking echocardiography (STE) has emerged as a valuable noninvasive tool for assessing myocardial deformation in patients with heart failure (HF). This review summarizes the principles, clinical applications, and prognostic implications of strain echocardiography across the spectrum of HF phenotypes, including heart failure with reduced ejection fraction (HFrEF), mildly reduced ejection fraction (HFmrEF), and preserved ejection fraction (HFpEF).Global longitudinal strain (GLS) provides a more sensitive and reproducible measure of left ventricular (LV) systolic function than traditional echocardiographic parameter like LV ejection fraction (EF), enabling early detection of subclinical dysfunction in stage A and B HF.In HFrEF, LVGLS adds incremental prognostic value beyond LVEF and identifies patients at risk for adverse outcomes. In HFmrEF, it helps characterize disease trajectory, guide therapy, and predict LVEF deterioration. In HFpEF, LVGLS uncovers subtle systolic impairment and stratifies risk. Additionally, left atrial (LA) and right ventricular (RV) strain measurements are increasingly recognized as important indicators of chamber-specific dysfunction and predictors of mortality, HF hospitalization, and atrial fibrillation. Despite vendor variability and the lack of universally accepted cut-offs, STE is becoming integral to HF evaluation. Pattern recognition of myocardial strains, such as apical sparing in amyloidosis, adds diagnostic value in cardiomyopathies. The integration of strain parameters enhances risk stratification, facilitates early diagnosis, and aids therapeutic monitoring in HF. Further standardization and broader clinical adoption of STE are needed to fully harness its prognostic and diagnostic capabilities in HF management.
