We assessed whether acid fast bacilli (AFB) determination in gastric lavage (GL) and bronchial lavage (BL) contributes to diagnosis in cases radiologically suggestive of pulmonary tuberculosis but with either negative AFB in sputum or the inability to expectorate sputum. Of 129 cases recruited for the study, 22 were excluded due to evaluation as inactive disease or non-tuberculosis disease. The remaining 107 cases were evaluated in 2 groups. Group A consisted of 49 patients that could not expectorate sputum and from whom GL was obtained. In group B, BL was performed in 58 patients that had negative sputum smear. Smear positivity was 61.2% (30/49) and culture positivity was 30.6% (15/49) in group A, 51.7% (30/58) and 81% (47/58), respectively, in group B. Thirteen cases, in whom AFB could not be detected microbiologically but who were radiologically strongly suggestive of tuberculosis, were regarded as tuberculosis according to "from treatment to diagnosis" criteria. In conclusion, detection of AFB positivity in the diagnosis of tuberculosis is important in terms of early initiation of treatment and detection of resistant bacilli. Therefore, we suggest that it would be helpful to obtain GL in cases where the patient is unable to expectorate sputum, and perform BL in cases with negative sputum smear.

Background: Metagenomic next-generation sequencing (mNGS) has emerged as a promising tool in clinical practice due to its unbiased approach to pathogen detection. Its diagnostic performance in pulmonary tuberculosis (PTB), however, remains to be fully evaluated.
Objective: This study aims to systematically review and Meta-analyze the diagnostic accuracy of mNGS in patients with PTB.

Background: Early evaluation of culture conversion after 6-month treatment of multidrug-resistant tuberculosis (MDR-TB) is vital for outcome prediction. This study aims to merge the maximum lesion cross-sectional area observed via computed tomography (CT) imaging during treatment to predict therapeutic response.
Methods: We retrospectively involved MDR-TB patients who completed 6 months of treatment from two hospitals.

The importance of fungal pathogens in cystic fibrosis (CF) patients and their diagnosis remains a challenge, so our aim was to analyze the influence of the detection of fungi in sputum by using conventional culture and molecular techniques, polymerase chain reaction (PCR), lateral flow devices (LFDs), and galactomannan (GM) on exacerbations in patients with cystic fibrosis. A prospective study was conducted in patients via follow-up in the CF Unit of the Central University Hospital of Asturias from January 2021 to April 2022. Adult patients with at least one documented exacerbation were included.

Background: Exposure-related changes in exhaled nitric oxide (FeNO) and sputum eosinophils have not been thoroughly compared in the investigation of occupational asthma.
Objective: This study aimed at comparing the accuracies of the changes in FeNO concentrations and sputum eosinophil counts in identifying asthmatic reactions induced by occupational agents during specific inhalation challenges (SICs).
Methods: This retrospective multicenter study included 321 subjects who completed an assessment of FeNO and sputum eosinophils before and 24 h after SICs with various occupational agents, of whom 156 showed a positive result.

BACKGROUND Human metapneumovirus (hMPV), classified in the Pneumoviridae family, is primarily known for causing lower respiratory tract infections in children, the elderly, and immunocompromised individuals. However, rare instances have shown that hMPV can also affect other systems, such as the cardiovascular system, leading to conditions like myocarditis. CASE REPORT We describe a 68-year-old man with a medical history of diabetes, hypertension, and liver cirrhosis who presented to the Emergency Department (ED) exhibiting symptoms of fever, cough, and dyspnea.
