Social cohesion emerging from a community-based physical activity program: A temporal network analysis.

Community-based physical activity programs, such as the Recreovía, are effective in promoting healthy behaviors in Latin America. To understand Recreovías' challenges and scalability, we characterized its social network longitudinally while studying its participants' social cohesion and interactions. First, we constructed the Main network of the program's Facebook profile in 2013 to determine the main stakeholders and communities of participants.

Evaluation of the Inclusion of Studies Identified by the FDA as Having Falsified Data in the Results of Meta-analyses: The Example of the Apixaban Trials.

This study evaluates the inclusion of studies identified by the FDA as having falsified data in the results of meta-analyses.

[Seroprevalence of Leptospira infection in habitants of peripheral neighborhoods in Cali, Colombia].

Introduction: Leptospirosis is a zoonotic disease with varying modes of transmission and clinical expression that affects humans inhabiting urban and rural areas worldwide. In Colombia, little is known regarding leptospirosis in urban settings.

Objectives: To establish the seroprevalence of leptospiral infection in humans, to assess the serological reactivity and to identify factors associated with seropositivity.

[Exposure to Leptospira in stray dogs in the city of Cali].

In Colombia, little information is available concerning the epidemiology of leptospirosis in urban environments. Furthermore, the role of dogs in the transmission cycle of leptospirosis in the urban setting is unclear. To explore the potential role of canines in the transmission of leptospirosis in Cali, a serological study was conducted with 197 serum samples collected from stray dogs during 2001 and 2003.

Photographic and luminometric detection of luciferase reporter phages for drug susceptibility testing of clinical Mycobacterium tuberculosis isolates.

Luciferase reporter phages (LRPs) have proven to be efficient tools for drug susceptibility testing of Mycobacterium tuberculosis. Luminometric detection of LRP activity offers higher sensitivity and quantitative results, while a Polaroid film detection method offers a "low-tech" inexpensive alternative that is called the Bronx box. In this work we evaluated, improved, and compared the performance of the luminometer and the Bronx box formats for drug susceptibility testing with LRPs by using 51 clinical isolates of M.
