Predictive factors associated with Bile culture positivity And phenotypiCal antIbiogram resistance patterns in patients taken to LaparOscopic cholecystectomy (BACILO): protocol for a prospective observational cohort study and development of a prognostic prediction model.

Introduction: Bile fluid is aseptic under normal conditions; however, in the presence of cholecystitis, its susceptibility to bacterial colonisation varies, with reported rates of 20%-70% of cases. This process is referred to as bactibilia and/or bacteriobilia and can be considered a secondary complication of biliary stasis and cholecystitis in general. In the management of acute cholecystitis, the antibiotic regimen should be prescribed based on the presumed pathogens involved, taking into consideration the risk factors for resistance patterns according to demographics and local exposure.

Blood eosinophils levels in a Colombian cohort of biomass-and tobacco-related COPD patients.

Introduction: Chronic obstructive pulmonary disease (COPD) is a major cause of illness and death among adults. In 2019, the Global Initiative for Chronic Obstructive Lung Disease (GOLD) strategy incorporated blood eosinophils as a biomarker to identify patients at increased risk of exacerbations which, with the history of exacerbations during the previous year, allows identification of patients who would benefit from anti-inflammatory treatment to reduce the risk of future exacerbations. The aim of this study was to describe demographic and clinical characteristics, eosinophil counts, and exacerbations in a cohort of COPD patients stratified by clinical phenotypes (non-exacerbator, frequent exacerbator, asthma-COPD overlap) in a Colombian cohort at 2600 meters above sea level.

Outcomes after laparoscopic cholecystectomy in patients older than 80 years: two-years follow-up.

Background: The laparoscopic cholecystectomy is the treatment of choice for patients with benign biliary disease. It is necessary to evaluate survival after laparoscopic cholecystectomy in patients over 80 years old to determine whether the long-term mortality rate is higher than the reported recurrence rate. If so, this age group could benefit from a more conservative approach, such as antibiotic treatment or cholecystostomy.

Risk factors associated to incisional hernia in stoma site after stoma closure: A systematic review and meta-analysis.

Background: This study aims to identify which risk factors are associated with the appearance of an incisional hernia in a stoma site after its closure. This in the sake of identifying which patients would benefit from a preventative intervention and thus start implementing a cost-effective protocol for prophylactic mesh placement in high-risk patients.

Methods: A systematic review of PubMed, Cochrane library, and ScienceDirect was performed according to PRISMA guidelines.
