OBJECTIVE A meta-analysis of randomized clinical trials (RCTs) was conducted to evaluate whether wound protectors reduce the risk of surgical site infection (SSI) after gastrointestinal and biliary tract surgery. BACKGROUND The effectiveness of impervious wound edge protectors for reduction of SSI remains unclear. METHODS A systematic review was conducted in Medline, EMBASE, and the Cochran...

Consider a network vulnerable to viral infection, where the security software can guarantee safety only to a limited part of it. We model this practical network scenario as a non-cooperative multiplayer game on a graph, with two kinds of players, a set of attackers and a protector player, representing the viruses and the system security software, respectively. Each attacker player chooses a nod...

OBJECTIVES To assess the acceptability and compliance with use of an energy-shunting hip protector in institutionalized elderly people. DESIGN AND SETTING A 6 month prospective follow-up in a Finnish nursing home. PARTICIPANTS 19 ambulatory nursing home residents with a high risk of hip fracture. MAIN OUTCOME MEASURES The proportion of the residents who were willing to use the device, the...

OBJECTIVES To investigate compliance with hip protector use. DESIGN Observational prospective study. SETTING 19 nursing homes (1040 beds). SUBJECTS All residents during an 18 month period were included in this study. INTERVENTION Hip protectors were introduced as a regular part of health care service for all residents. Residents at high risk were encouraged to use hip protectors regular...

Hip protectors are an effective strategy for reducing fall-related hip fractures in long-term care settings. The success of a hip protector program is enhanced by educational activities and administrative support, and a nurse champion to assume responsibility for the hip protector program.

Melanins are natural pigments distributed in living organisms and they are responsible for pigmentation of surface structure. In the present work, gel exclusion chromatography, spectrophotometric, and dielectric relaxation techniques were used to characterize DOPA melanin before and after irradiation with 60 Co gamma rays in the range of 5 to 50 Gy. The results show that the studied melanin is ...

PURPOSE To evaluate Tocoferol monoglucoside (TMG), a water soluble vit. E. in a phase I trial, as a radiation protector in those undergoing hemi-body radiation for disseminated disease. MATERIALS AND METHODS Patients scheduled to receive modified hemi-body radiation were accrued for the study. Patients not only had disseminated skeletal disease but, were heavily pretreated Seven patients were...

AIMS This study was undertaken to estimate the effect of hip protectors on the incidence of hip fracture when introduced into nursing homes as a regular part of the healthcare for all residents. METHODS A pre-test/test design was used. The pre-intervention period lasted 18 months from May 1996. The intervention period lasted 18 months from May 1998. During the intervention period all resident...

Environmental arsenic exposure, through drinking contaminated water, is a significant risk factor for developing vascular diseases and is associated with liver portal hypertension, vascular shunting, and portal fibrosis through unknown mechanisms. We found that the addition of low doses of arsenite to the drinking water of mice resulted in marked pathologic remodeling in liver sinusoidal endoth...
