Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and endoscopic ultrasound with bronchoscope-guided fine needle aspiration (EUS-B-FNA) are minimally invasive procedures for the diagnosis and staging of lung cancer. This study aimed to investigate the additional diagnostic value of EUS-B-FNA following EBUS-TBNA.
Methods: We performed a systematic literature review of PubMed, Embase, and the Cochrane Central Register databases and extracted the studies reporting the implementation of the combined EBUS-TBNA/EUS-B-FNA.

Background: The clinical efficacy of roflumilast, an oral phosphodiesterase-4 inhibitor, has been demonstrated in patients with severe chronic obstructive pulmonary disease (COPD). However, roflumilast has shown frequent adverse drug reactions (ADRs). This study was performed to investigate the dosing strategy that will improve adherence to roflumilast in COPD.

However, few studies have examined the association between the apoB/ApoA-I ratio and lung function. Therefore, we investigated whether this ratio is associated with decreased lung function in a large healthy cohort.

This study was performed to investigate the safety and tolerability of combination antifibrotic treatment in patients with IPF.
Methods: We conducted a proportional meta-analysis and searched PubMed, EMBASE, and the Cochrane Central Register for relevant clinical trials.

Background/aims: Antimicrobial de-escalation (ADE) remains a challenging strategy in the treatment of pneumonia. We investigated the outcomes of ADE as measured by mortality and duration of the use of antibiotics in patients with culture- negative pneumonia.
Methods: We performed a systematic review and meta-analysis in accordance with PRISMA guidelines.
Background/objective: Metabolic syndrome (MS) is related to lung dysfunction. However, its impact according to insulin resistance (IR) remains unknown. Therefore, we evaluated whether the relation of MS with lung dysfunction differs by IR.
View Article and Find Full Text PDFWe investigated the association of metabolically healthy (MH) and unhealthy (MU) obesity with incident lung dysfunction. This cohort study included 253,698 Korean lung disease-free adults (mean age, 37.4 years) at baseline.

We sought to determine the diagnostic yield of R-EBUS-guided transbronchial biopsy (TBB) without fluoroscopy.
Methods: We performed a systematic literature review using Pubmed, Embase, and the Cochrane Central Register.
Background: Timely and accurate diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is crucial to reduce the risk of viral transmission. We investigated the diagnostic accuracy of rapid antigen detection tests (RADTs) in the diagnosis of SARS-CoV-2 infection.
Methods: A systematic literature search was performed using Pubmed, Embase, and the Cochrane Central Register.
Background: Although the Quidel Sofia rapid influenza fluorescent immunoassay (FIA) is widely used to identify influenza A and B, the diagnostic accuracy of this test remains unclear. Thus, the objective of this study was to determine the diagnostic performance of this test compared to reverse transcriptase-polymerase chain reaction.
Methods: A systematic literature search was performed using MEDLINE, EMBASE, and the Cochrane Central Register.
Rapid and accurate diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is essential to prevent the spread of the virus. We investigated the diagnostic accuracy of the Xpert Xpress and the ID NOW assays for rapid detection of SARS-CoV-2 using a systemic review and meta-analysis approach. A systematic literature search was performed using PubMed, Embase, and the Cochrane COVID-19 Study Register.
View Article and Find Full Text PDFBackground/objectives: There has been inconsistent relationships between serum vitamin D levels and lung function in previous studies. However, previous studies included patients with medical diseases, affecting both vitamin D levels and lung function. Considering this view of potential confounders, we investigated if vitamin D deficiency (VDD) is linked to lung function in health screening examinee without overt medical conditions.
View Article and Find Full Text PDFObjectives: Though elevated ferritin level and decreased lung function both predispose people to cardio-metabolic disease, few reports have investigated the association between them. Furthermore, it remains unclear whether the association reflects a change in iron stores or an epiphenomenon reflecting metabolic stress. Therefore, we looked for possible associations between ferritin, iron, and transferrin saturation (TSAT) and lung function to clarify the role of iron-related parameters in healthy men.
View Article and Find Full Text PDFObjective: Bronchial hyperresponsiveness (BHR) is a representative feature of asthma. Although methacholine and mannitol are commonly used for bronchial challenge tests, the optimal roles of the two agents for assessing BHR remain unclear. We compared the diagnostic performance of methacholine and mannitol in bronchial challenge tests.
View Article and Find Full Text PDFBackground: Pulmonary hypertension (PH) is common in patients with idiopathic pulmonary fibrosis (IPF) and is associated with poor outcomes. This study was performed to determine the clinical efficacy of PH-specific therapeutic agents for IPF patients.
Methods: We performed a systematic review and meta-analysis using MEDLINE, EMBASE, and the Cochrane Central Register.
Background/aims: Although pneumococcal urinary antigen tests (PUATs) have universally been used for the diagnosis of pneumococcal pneumonia, data on the efficacy of these exams are limited. The objective of our study was to investigate the clinical impact of the PUAT in patients with community-onset pneumonia (CO-pneumonia).
Methods: We conducted a retrospective cohort study of patients diagnosed with CO-pneumonia.
Background: There has been no consensus regarding the discontinuation order of vasopressors in patients recovering from septic shock treated with concomitant norepinephrine (NE) and arginine vasopressin (AVP). The aim of this study was to compare the incidence of hypotension within 24 hours based on whether NE or AVP was discontinued first in order to determine the optimal sequence for discontinuation of vasopressors.
Methods: A systematic literature search was conducted in MEDLINE, Embase, and the Cochrane Central Register.
Purpose: We sought to elucidate the performance of a Quick Sequential Organ Function Assessment-65 (qSOFA-65) score in recognizing sepsis and to compare the qSOFA-65 score to systemic inflammatory response syndrome (SIRS) and qSOFA scores.
Methods: We performed a matched case-control study using propensity score matching. The number of patients meeting qSOFA-65, qSOFA, and SIRS positive criteria were calculated between the sepsis and non-sepsis groups.
Background: Although prior hospitalization (PH) has been considered as a risk factor for infection with potentially drug-resistant (PDR) pathogens in patients admitted with pneumonia, the evidence is limited. We aimed to elucidate the clinical impact of PH on these patients.
Methods: PH was defined as hospitalization for two or more days in the preceding 90 days.
Background: Decreased lung function is associated with non-alcoholic fatty liver disease (NAFLD), based on linking mechanisms such as insulin resistance and systemic inflammation However, its association with the risk of developing NAFLD is unclear. Our aim was to investigate whether baseline lung function is associated with incident NAFLD in middle-aged healthy Koreans.
Methods: A cohort study of 96,104 subjects (mean age: 35.
