Prevention and treatment of frailty in the postmenopausal woman.

Frailty is a complex subject, and all aspects of frailty are intertwined. This article identifies and discusses the individual aspects of frailty. These aspects, including sarcopenia, nutrition, obesity, relative strength, inflammatory markers, osteopenia and osteoporosis, aerobic capacity, absolute strength, balance, and prevention of frailty, must be reunited, albeit in varying combinations, if the effects of frailty on women are to be understood and treated. This article does not exhaust the topic, but covers what the authors consider to be the major issues.

The National Institute on Disability and Rehabilitation Research burn model system database: a tool for the multicenter study of the outcome of burn injury.

Advances in critical care and surgical management have significantly improved survival after burn injury over the past several decades. However, today, survival alone is an insufficient outcome. In 1994, the National Institute on Disability and Rehabilitation Research (NIDRR) created a burn model system program to evaluate the long-term sequelae of burn injuries. As part of this multicenter program, a comprehensive demographic and outcome database was developed to facilitate the study of a number of functional and psychosocial outcomes after burns. The purpose of this study is to review the database design and structure as well as the data obtained during the last 10 years. This is a descriptive study of the NIDRR database structure as well as the patient data obtained from the four participating burn centers from 1994 to 2004. Data obtained during hospitalization and at 6, 12, and 24 months after discharge were reviewed and descriptive statistics were calculated for select database fields. The database is divided into several subsections, including demographics, injury complications, patient disposition, and functional and psychological surveys. A total of 4600 patients have been entered into the NIDRR database. To date, 3449 (75%) patients were alive at discharged and consented to follow-up data collection. The NIDRR database provides an expansive repository of patient, injury, and outcome data that can be used to analyze the impact of burn injury on physical and psychosocial function and for the design of interventions to enhance the quality of life of burn survivors.

Optimal resistance training: comparison of DeLorme with Oxford techniques.

OBJECTIVE: Progressive resistive exercises, such as the DeLorme or Oxford techniques, improve strength by adding weights to arrive at the ten-repetition maximum (10RM; DeLorme) or by starting at the 10RM and removing weight (Oxford). The goal of this study was to examine the efficacy of each training method. DESIGN: In this randomized, prospective, group design, evaluator-blind clinical trial, 50 subjects performed either the Oxford or DeLorme weight-training techniques. Three times a week for 9 wks, subjects completed three sets of ten-repetition knee extensions based on the 10RM measured weekly. Incremental or decremental changes in training weight were utilized in training sessions based on the protocol randomly assigned to each subject. RESULTS: The mean 10RM increase was 71.9 kg for the DeLorme group and 67.5 kg for the Oxford group, which was not significantly different. Examination with repeated measures multivariate analysis of variance revealed no significant difference between the two groups for 10RM increase, and no significant sex differences were found. Percentage change scores were not significantly different for 1RM and 10RM for both protocols and sexes. CONCLUSION: Both protocol groups were able to complete their lifting assignments and progressed similarly in weekly 10RM weight lifted. It can be concluded that both the DeLorme and Oxford protocols improve strength with equivalent efficacy. Further studies involving a larger sample size are needed to address potential sex-specific changes in strength improvement in response to the protocols.
