We study the discrete and gauge symmetries of Quantum Electrodynamics at finite temperature within the the real-time formalism. The temperature dependent contributions to the effective two component Lagrangian are shown to be gauge dependent. However, the complete generating functional is gauge independent, condition which leads to the finite temperature Ward identities. These Ward identities r...

A pilot project was initiated and carried out by a multidisciplinary team working with older people with the aim of promoting effective practice in continence care. A documentation audit and staff questionnaire covering four independent hospital sites had identified the prevalence of urinary incontinence among inpatients to be 47%. This affected patients' participation in rehabilitation program...

Ward identities of SUSY and R-symmetry relate n-point amplitudes in supersymmetric theories. We review recent work in which these Ward identities are solved in N = 4 SYM and N = 8 supergravity. The solution, valid at both tree and loop level, expresses any NMHV superamplitude in terms of a basis of ordinary amplitudes. Basis amplitudes are classified by semi-standard tableaux of rectangular N -...

Although adequate bowel preparation is a prerequisite for colonoscopy, preparation among inpatients is often suboptimal. This study aimed to evaluate the impact of ward nurse education on the quality of bowel preparation of inpatients.A prospective, double-blinded, non-randomized, controlled study was performed. Expert endoscopists provided enhanced education to nurses who belonged to an "educa...

BACKGROUND Renovation of a general medical ward provided an opportunity to study health care facility design as a factor for preventing hospital-acquired infections. OBJECTIVE To determine whether a hospital ward designed with predominantly single rooms was associated with lower event rates of hospital-acquired infection and colonization. METHODS A prospective controlled trial with patient ...

PURPOSE Men at risk of missed prostate cancer on a negative biopsy often undergo a rebiopsy. We evaluated whether global hypomethylation, measured through LINE-1 methylation, and GSTP1 hypermethylation on a negative biopsy are associated with subsequent prostate cancer diagnosis. EXPERIMENTAL DESIGN We performed a case-control study nested in an unselected series of 737 men who received at le...

BACKGROUND Antibiotic consumption in hospitals is commonly measured using the accumulated amount of drugs delivered from the pharmacy to ward held stocks. The reliability of this method, particularly the impact of the length of the registration periods, has not been evaluated and such evaluation was aim of the study. METHODS During 26 weeks, we performed a weekly ward stock count of use of br...
