Impact of genital hygiene and sexual activity on urinary tract infection during pregnancy.

Introduction: Urinary tract infection (UTI) is a bacterial infection commonly occurring during pregnancy. The incidence of UTI in pregnant women depends on parity, race, and socioeconomic status and can be as high as 8%.

Objective: The objective was to determine the association of UTI with genital hygiene practices and sexual activity in pregnant women.

Transcutaneous electromagnetic induction heating of an intramedullary nickel-titanium shape memory implant.

Purpose: Inadequate mechanical stimuli are a major cause for nonunions following surgery for femoral and tibial shaft fractures. Adapting fixation rigidity during the course of fracture healing requires additional surgery. Nickel-titanium (NiTi) implants can change shape and rigidity by employing a temperature-dependent shape-memory effect.

Electromagnetic induction heating of an orthopaedic nickel--titanium shape memory device.

Shape memory orthopaedic implants made from nickel-titanium (NiTi) might allow the modulation of fracture healing, changing their cross-sectional shape by employing the shape memory effect. We aimed to show the feasibility and safety of contact-free electromagnetic induction heating of NiTi implants in a rat model. A water-cooled generator-oscillator combination was used.
