COPD is a heterogeneous disease with progressive airflow limitation. Despite therapeutic advances, current treatments poorly halt COPD progression. Disease stability (DS) is a proposed treatment goal, but its clinical significance remains uncertain.

Adjunctive corticosteroids improve outcomes in HIV-associated Pneumocystis jirovecii pneumonia (PCP), but their role in non-HIV-associated PCP is uncertain. Prior evidence largely has been limited to binary treatment groups and rarely has accounted for daily or cumulative dose effects.

The clade 2.3.4.4b highly pathogenic avian influenza (HPAI) virus H5N1 is the etiologic agent for an ongoing panzootic with a rapidly increasing number of human infections. Although morbidity and mortality in humans with this clade seems to be limited to date, previous HPAI H5N1 viruses have been associated with mortality rates of approximately 50% in humans. Not all cases of clade 2.3.4.4b influenza A(H5N1) HPAI in humans have been associated with known exposure to infected animals. Therefore, clinicians must be aware of the changing viral ecology, human risk factors, and clinical presentations associated with H5N1 viruses to facilitate early case recognition and management of clade 2.3.4.4b A(H5N1) HPAI infection in humans.

The etiology of pulmonary arterial hypertension (PAH) is complex and the risk is heterogeneous. Growth differentiation factor-15 (GDF-15) has been reported to be associated with the prognosis of patients with PAH, but whether the use of GDF-15 as an additional prognostic biomarker can improve preexisting PAH risk stratification remains unclear.

Management of spontaneous pneumothorax often involves intercostal chest drain (ICD) insertion. Determining when to remove the ICD is controversial, with significant variation in practice. Establishing optimal ICD management in pneumothorax could reduce morbidity and improve cost-effectiveness.
273. Impact of Elevated Pulmonary Arterial Wedge Pressure on Safety and Efficacy of Balloon Pulmonary Angioplasty in the Treatment of Chronic Thromboembolic Pulmonary Hypertension.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare condition caused by thromboembolic occlusions of the pulmonary arteries and characterized by elevated pulmonary pressure, vascular remodelling, and right ventricular overload, which can be treated effectively with balloon pulmonary angioplasty (BPA). The study aimed to evaluate whether elevated pulmonary arterial wedge pressure (PAWP), associated with left ventricular dysfunction, influences the effectiveness and safety of BPA treatment.

Survivors of critical illness face fragmented care transitions, leading to readmissions, emergency care use, and death. The Veterans Affairs (VA) Patient Aligned Care Team model emphasizes coordinated outpatient follow-up, yet many veterans now receive VA-purchased intensive care at community hospitals, potentially disrupting continuity.

Pulse oximetry-derived measures of autonomic vascular re-activity during sleep, quantified by pulse wave amplitude drop (PWAD) characteristics such as the PWAD index, have recently been proposed as a biomarker of cardiovascular disease (CVD) outcomes in patients with OSA.

Bronchopulmonary dysplasia (BPD) is the most common neonatal lung parenchymal disease characterized by obstructive and restrictive lung abnormalities. Evaluation of neonatal BPD lung disease using MRI has been shown to be more sensitive to short-term outcomes than standard clinical measures. However, the longitudinal trajectory of parenchymal disease remains poorly characterized.
