Objective: The main goal of this research was to determine the frequency of hantavirus-specific antibodies in rodents from the municipality of San Marcos in the Sucre department of Colombia.
Methods: 144 rodents were captured in San Marcos' urban and rural areas using Sherman traps between December 2007 and July 2009. "Virus sin Nombre" (SNV)-specific antibodies were detected in plasma samples by an indirect ELISA immunoassay.
Results: An 8.3 % (12/144) seroprevalence rate was found. Specific seropositivity rates ranged from 6.8 % (3/44, Zygodontomysbrevicauda) to 50 % (1/2, Neacomysspinosus). No significant differences were found in seroprevalence according to capture area, gender and/or reproductive stage (p>0.05); however, there were more seropositive adult males.
Conclusion: This is the first evidence of hanta virus seropositivity in rodents from the Murinae subfamily in Colombia. The presence of SNV antibodies in rodents in San Marcos supported the hypothesis that at least one hantavirusis circulating in rodents from northern Colombia.

Background: Chronic cough is a common respiratory symptom with an impact on daily activities and quality of life. Global prevalence data are scarce and derive mainly from European and Asian countries and studies with outcomes other than chronic cough. In this study, we aimed to estimate the prevalence of chronic cough across a large number of study sites as well as to identify its main risk factors using a standardised protocol and definition.

Background: Over-reliance on short-acting β-agonists (SABAs) is associated with poor asthma outcomes. However, the extent of SABA use in Turkey is unclear owing to a lack of comprehensive healthcare databases. Here, we describe the demographics, disease characteristics and treatment patterns from the Turkish cohort of the SABA use IN Asthma (SABINA) III study.

Background/aim: Phase III trials have demonstrated a significant efficacy and an acceptable safety for pirfenidone in patients having mild to moderate idiopathic pulmonary fibrosis (IPF). Real-life data on the use of pirfenidone 200 mg tablets are limited. This study aimed to investigate the efficacy and safety of pirfenidone 200 mg tablets for the treatment of IPF in a real-life setting.

Background: Pneumonia is a common and severe complication of abdominal surgery, it is associated with increased length of hospital stay, healthcare costs, and mortality. Further, pulmonary complication rates have risen during the SARS-CoV-2 pandemic. This study explored the potential cost-effectiveness of administering preoperative chlorhexidine mouthwash versus no-mouthwash at reducing postoperative pneumonia among abdominal surgery patients.
