BACKGROUND: Timely administration of antibiotics is one of the most important interventions in reducing mortality in sepsis. However, administering antibiotics within a strict time threshold in all patients suspected with sepsis will require huge amount of effort and resources and may increase the risk of unintentional exposure to broad-spectrum antibiotics in patients without infection with its consequences. Thus, controversy still exists on whether clinicians should target different time-to-an

Curative resection for NSCLC in healthy elderly patients appeared feasible with 10% PPCs. ASA classification ≥3, lower BMI, presence of ILA on CT, and larger extent of resection are predictors of PPC development, which guide treatment decision-making in these patients.

Current sepsis biomarkers may be helpful in determining organ failure and evaluating patient clinical course; however, direct molecular biomarkers to predict subsequent organ failure have not yet been discovered. Exosomes, a small population of extracellular vesicles, play an important role in the inflammatory response, coagulation process and cardiac dysfunction in sepsis. Nonetheless, the association of plasma exosome with severity and mortality of sepsis is not well known. Therefore, the over

BACKGROUND: Interstitial lung abnormalities (ILAs) are associated with the risk of lung cancer and its mortality. However, the impact of ILA on treatment-related complications and survival in patients who underwent curative surgery is still unknown. RESEARCH QUESTION: This study aimed to evaluate the significance of the presence of computed tomography-diagnosed ILA and histopathologically matched interstitial abnormalities on postoperative pulmonary complications (PPCs) and the long-term surviva

CD63 is one of the tetraspanin protein family members that is ubiquitously expressed on exosomes and is involved in the signal transduction of various types of immune cells. It may thus contribute to immunometabolic mechanisms of cellular and organ dysfunction in sepsis. Nonetheless, the association of exosomal CD63 with the severity and mortality of sepsis is not well known. Therefore, in the present study, the overall levels of exosomal CD63 were evaluated to ascertain whether they were associ

Bronchiectasis has an increasing prevalence and substantial clinical and economic burden. Therefore, physicians should identify patients with bronchiectasis at high risk of disease progression to ensure optimal management in advance. The heterogeneity of bronchiectasis means it is unlikely that any single parameter could identify highrisk patients; therefore, disease severity is usually assessed using validated composite tools, such as the Bronchiectasis Severity Index, FACED, and Bronchiectasis

<title>Abstract</title> Background It is unclear whether the administration of antibiotics within 1 hour could improve patient outcomes in sepsis, and whether the association of time to antibiotics administration and clinical outcomes are different for sepsis and septic shock. Methods This study analyzed prospectively collected data from an ongoing multicenter cohort of patients with sepsis identified in the emergency department. Adjusted odds ratios (ORs) were compared for in-hospital mortality

The subjects with cLy1/2 had better overall survival than those with cLy3/4 or intrapulmonary metastases. cLy1/2 seems to be a T descriptor (T3/4) rather than an M1 descriptor.

Background Preserved ratio impaired spirometry (PRISm) is associated with increased cardiovascular disease (CVD) risk and mortality. However, a causal relationship between PRISm and CVD remains unclear. We investigated the progression of coronary artery calcium (CAC) scores based on the presence of PRISm and reduced forced vital capacity (FVC). Methods This retrospective cohort study included 11 420 participants aged ≥40 years with forced expiratory volume in 1 s (FEV 1 )/FVC ≥0.7 who underwent

Abstract Rationale Numerous studies indicate that preserved-ratio impaired spirometry (PRISm) is associated with adverse clinical outcomes. However, the impact of PRISm severity, particularly in regard to forced vital capacity (FVC), on mortality risk remains unclear. Objectives To determine whether PRISm was associated with mortality and to identify specific groups with particularly increased mortality rates. Methods This retrospective study enrolled individuals aged &amp;gt;40 years who underw

There is limited evidence regarding the causal inference of emphysema and functional small airway disease in the subsequent progression of chronic obstructive pulmonary disease (COPD). Patients consisting of two independent cohorts diagnosed with COPD and underwent two serial chest CT scans were included. Total percent emphysema (PRM Emph ) and fSAD (PRM fSAD ) was quantified via PRM. To investigate the progression of emphysema, we divided COPD patients with PRM Emph < 10% into low and high PRM
