Modifiable risk factors for RA: prevention, better than cure?

Objective. To perform a meta-synthesis of the evidence for modifiable lifestyle risk factors for inflammatory polyarthritis (IP) and RA

[Colovesical fistula secondary to the migration of a biliary stent. Case report]

BACKGROUND: The endoscopic placement of endoprostheses to decompress biliary obstruction is a commonly used treatment for malignant biliary diseases and is also used in the treatment of benign biliary strictures. Unusual complications of endoprosthesis placement have been described and include the migration of the stent. We present a case to share with the scientific community, an unusual complication secondary to the migration of a biliary stent that has not previously been reported to our knowledge. CASE REPORT: We present the case of a 47-year-old female with a diagnosis of benign papillary stenosis. The patient received a biliary endoprosthesis with clinical improvement. Later she underwent open cholecystectomy and common duct exploration. At consultation 18 months later, the patient presents with indistinct lower abdominal pain and dysuria. We performed imaging studies where the biliary stent was observed, partly in the sigmoid colon and partly in the bladder. The patient underwent surgery where a colovesical fistula was found and treated during the same surgical event. The patient was discharged succesfully

Measurement of charged particle spectra in minimum-bias events from proton-proton collisions at root s =13 TeV

Pseudorapidity, transverse momentum, and multiplicity distributions are measured in the pseudorapidity range vertical bar eta vertical bar 0.5 GeV in proton-proton collisions at a center-of-mass energy of root s = 13 TeV. Measurements are presented in three different event categories. The most inclusive of the categories corresponds to an inelastic pp data set, while the other two categories are exclusive subsets of the inelastic sample that are either enhanced or depleted in single diffractive dissociation events. The measurements are compared to predictions from Monte Carlo event generators used to describe high-energy hadronic interactions in collider and cosmic-ray physics.Peer reviewe
