Surgical site infection in hepatobiliary surgery patients and its relationship with serum vitamin D concentration.

Introduction: While several studies have examined the correlation between vitamin D concentrations and post-surgical nosocomial infections, this relationship has yet to be characterized in hepatobiliary surgery patients. We investigated the relationship between serum vitamin D concentration and the incidence of surgical site infection (SSI) in patients in our hepatobiliary surgery unit.

Methods: Participants in this observational study were 321 successive patients who underwent the following types of interventions in the hepatobiliary surgery unit of our center over a 1-year period: cholecystectomy, pancreaticoduodenectomy, total pancreatectomy, segmentectomy, hepatectomy, hepaticojejunostomy and exploratory laparotomy.

Association between preoperative levels of 25-hydroxyvitamin D and hospital-acquired infections after hepatobiliary surgery: A prospective study in a third-level hospital.

Introduction: Evidence implicates vitamin D deficiency in poorer outcomes and increased susceptibility to hospital-acquired infections (HAIs). This study examined the association between serum vitamin D levels and HAIs in a population of hepatobiliary surgery patients.

Methods: Participants in this prospective analytical observational study were patients who underwent hepatobiliary surgery in a tertiary hospital in Aragon, Spain, between February 2018 and March 2019.

[Kingella kingae pediatric septic arthritis].

Kingella kingae is a bacterium that colonizes the upper respiratory tract. Despite its low pathogenicity in this location, previous respiratory pathological processes may favor its systemic spread causing bone and joint infections, mainly in children under five years. It can be considered an emerging pathogen in osteoarticular infection in pediatric patients.

[Serologic diagnosis of congenital toxoplasmosis].

Objective: To investigate the serological diagnosis of congenital toxoplasmosis and the prevalence of antibodies against toxoplasma in pregnant women in our area.

Method: Toxoplasmosis seroprevalence was analyzed in 68 712 serum samples from 47 635 pregnant women living in the catchment area of Hospital Miguel Servet during the period of 1992 to 2008. Detection of toxoplasma-specific immunoglobulins (IgM, IgA, IgG) and IgG avidity studies were carried out in the microbiology laboratory.
