RESUMO
BACKGROUND: In the literature, there is a wide range of reported morbidity and mortality rates after acute paraesophageal hernia (PH) repair. MATERIALS AND METHODS: Data were collected from all patients undergoing PH repair between December 2001 and October 2011. Outcome data were compared between the acute and elective groups. RESULTS: Over the study period, 268 patients underwent PH repair, of which 42 patients underwent acute repair compared with 226 elective repairs. Morbidity and mortality rates were both higher, albeit nonsignificantly, in the acute group (16.6% vs. 6.6%, P=0.058 and 4.8% vs. 0.4%, P=0.065, respectively). CONCLUSIONS: Because of the poorer preoperative medical status, lower success rates of minimal access surgery, and longer inpatient stay, combined with the trends toward increased morbidity and mortality rates, of patients undergoing acute repair of PH, we would recommend routine elective laparoscopic surgery as the standard of care for individuals with symptomatic PH and minimal comorbidities.

BACKGROUND: The incidence and etiology of falls in patients following hip fracture remains poorly understood. METHODS: We prospectively investigated the incidence of, and risk factors for, recurrent and injurious falls in community-dwelling persons admitted for surgical repair of minimal-trauma hip fracture. Fall surveillance methods included phone calls, medical records, and fall calendars. Potential predictors of falls included health status, quality of life, nutritional status, body composition, muscle strength, range of motion, gait velocity, balance, walking endurance, disability, cognition, depression, fear of falling, self-efficacy, social support, physical activity level, and vision. RESULTS: 193 participants enrolled in the study (81 +/- 8 years, 72% women, gait velocity 0.3 +/- 0.2 m/s). We identified 227 falls in the year after hip fracture for the 178 participants with fall surveillance data. Fifty-six percent of participants fell at least once, 28% had recurrent falls, 30% were injured, 12% sustained a new fracture, and 5% sustained a new hip fracture. Age-adjusted risk factors for recurrent and injurious falls included lower strength, balance, range of motion, physical activity level, quality of life, depth perception, vitamin D, and nutritional status, and greater polypharmacy, comorbidity, and disability. Multivariate analyses identified older age, congestive heart failure, poorer quality of life, and nutritional status as independent risk factors for recurrent and injurious falls. CONCLUSIONS: Recurrent and injurious falls are common after hip fracture and are associated with multiple risk factors, many of which are treatable. Interventions should therefore be tailored to alleviating or reversing any nutritional, physiological, and psychosocial risk factors of individual patients.

BACKGROUND: Thigh muscle mass and cross-sectional area (CSA) are useful indexes of sarcopenia and the response to treatment in older patients. Current criterion methods are computed tomography (CT) and magnetic resonance imaging. OBJECTIVE: The objective was to compare thigh muscle mass estimated by dual-energy X-ray absorptiometry (DXA), a less expensive and more accessible method, with thigh muscle CSA determined by CT in a group of elderly patients recovering from hip fracture. DESIGN: Midthigh muscle CSA (in cm(2)) was assessed from a 1-mm CT slice and midthigh muscle mass (g) from a 1.3-cm DXA slice in 30 patients (24 women) aged 81 +/- 8 y during 12 mo of follow-up. Fat-to-lean soft tissue ratios were calculated with each technique to permit direct comparison of a variable in the same units. RESULTS: Baseline midthigh muscle CSA was highly correlated with midthigh muscle mass (r = 0.86, P < 0.001) such that DXA predicted CT-determined CSA with an SEE of 10 cm(2) (an error of approximately 12% of the mean CSA value). CT- and DXA-determined ratios of midthigh fat to lean mass were similarly related (intraclass correlation coefficient = 0.87, P < 0.001). When data were expressed as the changes from baseline to follow-up, CT and DXA changes were weakly correlated (intraclass correlation coefficient = 0.51, P = 0.019). CONCLUSIONS: Assessment of sarcopenia by DXA midthigh slice is a potential low-radiation, accessible alternative to CT scanning of older patients. The errors inherent in this technique indicate, however, that it should be applied to groups of patients rather than to individuals or to evaluate the response to interventions.

BACKGROUND: Currently 1 in 11 women over the age of 60 in Australia are diagnosed with breast cancer. Following treatment, most breast cancer patients are left with shoulder and arm impairments which can impact significantly on quality of life and interfere substantially with activities of daily living. The primary aim of the proposed study is to determine whether upper limb impairments can be prevented by undertaking an exercise program of prolonged stretching and resistance training, commencing soon after surgery. METHODS/DESIGN: We will recruit 180 women who have had surgery for early stage breast cancer to a multicenter single-blind randomized controlled trial. At 4 weeks post surgery, women will be randomly assigned to either an exercise group or a usual care (control) group. Women allocated to the exercise group will perform exercises daily, and will be supervised once a week for 8 weeks. At the end of the 8 weeks, women will be given a home-based training program to continue indefinitely. Women in the usual care group will receive the same care as is now typically provided, i.e. a visit by the physiotherapist and occupational therapist while an inpatient, and receipt of pamphlets. All subjects will be assessed at baseline, 8 weeks, and 6 months later. The primary measure is arm symptoms, derived from a breast cancer specific questionnaire (BR23). In addition, range of motion, strength, swelling, pain and quality of life will be assessed. DISCUSSION: This study will determine whether exercise commencing soon after surgery can prevent secondary problems associated with treatment of breast cancer, and will thus provide the basis for successful rehabilitation and reduction in ongoing problems and health care use. Additionally, it will identify whether strengthening exercises reduce the incidence of arm swelling. TRIAL REGISTRATION: The protocol for this study is registered with the Australian Clinical Trials Registry (ACTRN012606000050550).

BACKGROUND: Total body potassium (TBK) is known to decline throughout adulthood. The relations between physical activity, age, anabolic hormones, and TBK have rarely been considered. OBJECTIVE: We sought to describe the relation between habitual physical activity, age, serum estradiol, and insulin-like growth factor I (IGF-I) and TBK in postmenopausal women. DESIGN: TBK, fat-free mass (FFM), moderate-to-vigorous-intensity physical activity (MVPA; assessed with use of a semistructured interview), and serum concentrations of estradiol, IGF-I, and IGF binding protein 3 (IGFBP-3) were quantified in 51 healthy white women aged 54-76 y. RESULTS: The potassium content of FFM declined curvilinearly with age, indicating an accelerated loss of skeletal muscle after 65 y of age. With the data split into high (n = 25) and low (n = 26) MVPA groups, the active women had 6.5% more potassium per FFM than did their less-active counterparts (P < 0.01). In multiple regression analysis, MVPA was the major determinant of the potassium content of FFM (P = 0.02), such that an active 70-y-old had the potassium content value of a 55-y-old sedentary woman. Serum estradiol, IGF-I, and IGFBP-3 were not significant determinants of the potassium content of FFM. CONCLUSIONS: These data suggest that 1) habitual physical activity can significantly influence FFM potassium content; 2) physical activity must, therefore, be considered if the effect of aging per se on TBK is to be clarified; and 3) MVPA, such as that pursued by the active women in the present study (eg, walking, dancing, floor exercises, and swimming), can assist in preventing sarcopenia in older women.
