Osteaoarticular infection due to C. acnes are known to be of late onset, causing chronic infection possibly pauci-symptomatic. Osteaoarticular infection due to C. acnes represents a diagnostic challenge, since C. acnes is slow and difficult to grow, and can also be considered a contaminant.A 16S universal PCR bacteriological diagnosis has been proposed but is lacking of sensitivity. A specific C. acnes PCR was developed in 2010, but is not used routinely.

Respiratory virus infections cause a majority of asthma exacerbations in the fall to spring months. Current diagnostic platforms for respiratory viruses have limitations including cost, availability, and invasiveness. The use of noninvasive breath collection to analyze breath metabolites may be used to differentiate virus-infected asthmatics from other causes of acute asthma exacerbations.

This study is a retrospective, observational study to evaluate minocycline use in participants under real world conditions.

The mode of delivery affects the diversity and colonization pattern of the gut microbiota during the first year of infants' life. Probiotics have been observed to positively influence the host's health, but to date few data about the ability of probiotics to modify the gut microbiota composition exist. 40 newborns born by elective caesarian sectional be randomized to a Lactobacillus kefiri LKF01 DSM32079 (LKEF) supplementation or placebo for 21 days. Changes in the gut microbiota composition were detected by using a Next Generation Sequencing technology.

This is a retrospective chart review using Electronic Privacy Identification Center (EPIC) database to determine if the addition of cranberry juice capsules to our discharge medication regimen for patients discharged home with an indwelling urinary catheter following pelvic floor gynecology surgery reduced the incidence of UTI.

This was a prospective study performed between November 2011 and September 2013. Patients with a confirmed S. aureus infection after fracture fixation or prosthetic joint infection were included. Exclusion criteria included infections involving external fixation pins, infections without any implanted hardware and culture positive patients not displaying any clinical sign of infection. The following surgical parameters were documented: affected bone or joint; type of implant; time between implantation of the device and onset of symptoms. Personal characteristics and patients'health status were also documented. Any revision surgeries involving the site of interest and all isolated pathogens were recorded throughout the course of treatment and follow-up. A follow up examination was performed an average of 23 months after discharge. Primary outcome at follow up was cure. Cure was defined by the authors as: missing local (at site of interest) or systemic signs of infection, terminated surgical and systemic therapy and restoration of joint or limb function. At the first surgical procedure after enrolment, at least four deep bone biopsies were taken from the interface between implant and affected bone. Identification and antibiotic susceptibility testing of all growth was performed. Multi-drug-resistance (MDR) was defined according to the definitions of the European Committee of Antimicrobial Susceptibility Testing (EUCAST). Biofilm formation was analysed and quantified in microtitre plate assays according to protocol of Stepanovic et al.(see references).

The purpose of this study was to determine whether moderate-severe endpoints (including high fever, lower respiratory tract disease, acute otitis media, or serious extra-pulmonary complications) were predictive of hospitalization, intensive care admission, antibiotic use and other complications in children under 8 years of age.

Nosocomial pneumonia is the third causes of nosocomial infection. In intensive care unit, their incidence is even higher, of the order of 10 to 30% in patients with invasive mechanical ventilation (IMV). One of the main mechanisms behind VAP (Ventilator-Associated Pneumonia) is the passage of germs colonizing the oropharynx to the subglottic airways. The presence of a nasogastric tube, immobilization, and strict dorsal decubitus increase the risk of colonization of the tracheobronchial tree and pneumonia in these patients. To reduce the incidence of VAP, several strategies have been developed in intensive care to try to control these different risk factors. These sets of measures, also called "bundle" systematically include the control of the elevation of the patient's head more than 30 °. Nevertheless, the strict and permanent control of the elevation of the patient's head is difficult to obtain. One of the reasons that may explain the difficulty of ensuring a correct elevation is the absence of visual cues that are easy to obtain on the beds of patients. An easily identifiable visual cue at the head of the bed would probably provide a satisfactory elevation (greater than 30 °) in patients intubated in intensive care. Our hypothesis is that the addition to the head of the patient's bed of a visible mark that is easily visible and easily interpretable by all the nurses will improve the elevation of the head of the patients in intensive care.

The intention of the study is to explore metabolic and inflammatory parameters in the pelvis after abdominoperineal resection for locally advanced rectal cancer in patients that have received radiation therapy before surgery.
