JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 8 2009
Peggy Mannen Cawthon PhD
OBJECTIVES: To examine the association between strength, function, lean mass, muscle density, and risk of hospitalization. DESIGN: Prospective cohort study. SETTING: Two U.S. clinical centers. PARTICIPANTS: Adults aged 70 to 80 (N=3,011) from the Health, Aging and Body Composition Study. MEASUREMENTS: Measurements were of grip strength, knee extension strength, lean mass, walking speed, and chair stand pace. Thigh computed tomography scans assessed muscle area and density (a proxy for muscle fat infiltration). Hospitalizations were confirmed by local review of medical records. Negative binomial regression models estimated incident rate ratios (IRRs) of hospitalization for race- and sex-specific quartiles of each muscle and function parameter separately. Multivariate models adjusted for age, body mass index, health status, and coexisting medical conditions. RESULTS: During an average 4.7 years of follow-up, 1,678 (55.7%) participants experienced one or more hospitalizations. Participants in the lowest quartile of muscle density were more likely to be subsequently hospitalized (multivariate IRR=1.47, 95% confidence interval (CI)=1.24,1.73) than those in the highest quartile. Similarly, participants with the weakest grip strength were at greater risk of hospitalization (multivariate IRR=1.52, 95% CI=1.30,1.78, Q1 vs. Q4). Comparable results were seen for knee strength, walking pace, and chair stands pace. Lean mass and muscle area were not associated with risk of hospitalization. CONCLUSION: Weak strength, poor function, and low muscle density, but not muscle size or lean mass, were associated with greater risk of hospitalization. Interventions to reduce the disease burden associated with sarcopenia should focus on increasing muscle strength and improving physical function rather than simply increasing lean mass. [source]


Adverse Outcomes of Osteoporotic Fractures in the General Population,

JOURNAL OF BONE AND MINERAL RESEARCH, Issue 6 2003
L Joseph Melton III MD
Abstract Osteoporotic fractures exact a terrible toll on the population with respect to morbidity and cost, and to a lesser extent mortality, which will increase dramatically with the growing elderly population. Attention has focused on the 12-20% excess deaths after hip fracture, but most are caused by underlying medical conditions unrelated to osteoporosis. More important is fracture-related morbidity. An estimated 10% of patients are disabled by hip fracture, and 19% require institutionalization, accounting for almost 140,000 nursing home admissions annually in this country. Distal forearm and vertebral fractures less commonly result in nursing home placement, but about 10% of postmenopausal women have vertebral deformities that cause chronic pain, and a substantial minority have poor function after forearm fracture. These fractures interfere greatly with the activities of daily living, and all of them can have a substantial negative impact on quality of life. Annual expenditures for osteoporotic fracture care in the United States ($17.5 million in 2002 dollars) are dominated by hip fracture treatment, but vertebral fractures, distal forearm fractures, and importantly, the other fractures related to osteoporosis contribute one-third of the total. Although all fracture patients are at increased risk of future fractures, few of them are currently treated for osteoporosis, and only a subset (i.e., those with vertebral fractures) are considered candidates for many clinical trials. Eligibility criteria should be expanded and fracture end-points generalized to acknowledge the overall burden of osteoporotic fractures. [source]


A reconstructed digit by transplantation of a second toe for control of an electromechanical prosthetic hand

MICROSURGERY, Issue 1 2002
Zhong Wei Chen M.D.
The treatment options for the loss of an entire human hand and part of the forearm are currently limited to the transplantation of toe(s) to the amputation stump or a Krukenberg's bifurcation hand, and using a cosmetic or functional prosthesis. The functional prosthetic hand, such as the prevailing myoelectrically controlled prosthetic hand, has an action accuracy that is affected by many factors. The acceptance rate of the three planes freedom myoelectronic hand by the patients was 46,90% because of poor function caused by the weakness of signal and strong external interference. In this report, the left second toe was transplanted to the patient's forearm amputation stump. Mandates from the brain are relayed by the action of this reconstructed digit, to control a special designed multidimension freedom electronic prosthetic hand. After rehabilitation and adaptation training, the correct recognition rate of the electronic prosthetic hand controlled by this reconstructed digit is a remarkable 100%. © 2002 Wiley-Liss, Inc.

An Analysis of the Components of Pain, Function, and Health-Related Quality of Life in Patients with Failed Back Surgery Syndrome Treated with Spinal Cord Stimulation or Conventional Medical Management

NEUROMODULATION, Issue 3 2010
FRCA, Sam Eldabe MB
Objectives:, Failed back surgery syndrome (FBSS) patients experience pain, functional disability, and reduced health-related quality of life (HRQoL) despite anatomically successful surgery. Examining sub-dimensions of health outcomes measures provides insight into patient well-being. Materials and Methods:, The international multicenter PROCESS trial collected detailed HRQoL (EuroQol-5D; Short-Form 36) and function (Oswestry Disability Index) information on 100 FBSS patients. Results:, At baseline, patients reported moderate-to-severe leg and back pain adversely affecting all dimensions of function and HRQoL. Compared with conventional medical management alone, patients also receiving spinal cord stimulation (SCS) reported superior pain relief, function, and HRQoL at six months on overall and most sub-component scores. The majority of these improvements with SCS were sustained at 24 months. Nonetheless, 36,40% of patients experienced ongoing marked disability (standing, lifting) and HRQoL problems (pain/discomfort). Conclusions:, Longer-term patient management and research must focus on these refractory FBSS patients with persisting poor function and HRQoL outcomes. [source]


Surgical Salvage after Failed Irradiation for Vestibular Schwannoma

THE LARYNGOSCOPE, Issue 10 2005
Rick A. Friedman MD
Abstract Objectives/Hypothesis: Compare vestibular schwannoma (VS) surgical outcome between patients with prior irradiation and those not previously treated. Study Design: Retrospective review with matched control group. Methods: Review of tumor adherence to the facial nerve, facial nerve grade, and complications in 38 patients with radiotherapy as a primary procedure before VS surgical removal and a matched random sample of 38 patients with primary surgery. The majority of the irradiated group had gamma knife radiation therapy. Mean time from irradiation to surgical salvage was 3.3 years (SD = 3.2), with a minimum of 5.2 months and a maximum of 15.8 years. Most (89.5%) patients in each group underwent a translabyrinthine approach. Mean tumor size at surgery was 2.6 cm in each group. Results: The irradiated group had more moderate to severe adherence of tumor than the controls (89% vs. 63%, P , .01). They also had a lower rate of good facial function (House-Brackmann grade I/II) (37% vs. 70%) and a higher rate of poor function (grades V or VI) (50% vs. 18%) at follow-up (P , .019). Results were similar when including only those with good preoperative function (50% vs. 72% and 32% vs. 15%) but did not achieve statistical significance. Surgical time and complications did not differ. Conclusion: Patients who have undergone irradiation for VS and require surgical salvage may have a more difficult surgery and poorer outcomes than those not previously irradiated. When making their initial choice of treatment, patients should be counseled that surgery might be more difficult after failed stereotactic irradiation. [source]


Direct medical costs and their predictors in patients with rheumatoid arthritis

ARTHRITIS & RHEUMATISM, Issue 10 2003
527 patients, A three-year study of
Objective To estimate total direct medical costs in persons with rheumatoid arthritis (RA) and to characterize predictors of these costs. Methods Patients (n = 7,527) participating in a longitudinal study of outcome in RA completed 25,050 semiannual questionnaires from January 1999 through December 2001. From these we determined direct medical care costs converted to 2001 US dollars using the consumer price index. We used generalized estimating equations to examine potential predictors of the costs. Monte Carlo simulations and sensitivity analyses were performed to evaluate the varying prevalence and cost of biologic therapy. Results The mean total annual direct medical care cost in 2001 for a patient with RA was $9,519. Drug costs were $6,324 (66% of the total), while hospitalization costs were only $1,573 (17%). Approximately 25% of patients received biologic therapy. The mean total annual direct cost for patients receiving biologic agents was $19,016 per year, while the cost for those not receiving biologic therapy was $6,164. RA patients who were in the worst quartile of functional status, as measured by the Health Assessment Questionnaire, experienced direct medical costs for the subsequent year that were $5,022 more than the costs incurred by those in the best quartile. Physical status as determined by the Short Form 36 physical component scale had a similar large effect on RA costs, as did comorbidity. Medical insurance type played a more limited role. However, those without insurance had substantially lower service utilization and costs, and health maintenance organization patients had lower drug costs and total medical costs. Increased years of education, increased income, and majority ethnic status were all associated with increased drug costs but not hospitalization costs. Costs in all categories decreased after age 65 years. Conclusion Estimates of direct medical costs for patients with RA are substantially higher than cost estimates before the biologic therapy era, and costs are now driven predominantly by the cost of drugs, primarily biologic agents. RA patients with poor function continue to incur substantially higher costs, as do those with comorbid conditions, and sociodemographic characteristics also play an important role in determination of costs.

Quality of life during potentially curative treatment for locally advanced oesophageal cancer,

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 11 2007
K. N. L. Avery
Background: Combination chemoradiotherapy with or without surgery are internationally applied alternative strategies for potential cure of oesophageal cancer. This study compared health-related quality of life (HRQL) between patients selected for chemoradiation and those who had combination treatment including oesophagectomy. Methods: Patients with stage II or III oesophageal cancer completed HRQL assessments at baseline, at the worst expected HRQL time point and at expected recovery. HRQL was compared between groups using linear regression, adjusting for age, sex, performance status, tumour stage and type, and baseline HRQL. Results: Some 132 patients began treatment, of whom 51 had chemoradiotherapy and 81 combination treatment including surgery. Patients selected for chemoradiotherapy were older, more likely to have squamous cell cancer and reported poorer HRQL than those selected for surgery. At the worst expected time point after treatment, both groups reported multiple symptoms and poor function, but surgery was associated with a greater reduction in HRQL from baseline than chemoradiotherapy. Recovery of HRQL was achieved within 6 months after chemoradiotherapy, but complete recovery had not occurred 6 months after surgery and there was persistent significant deterioration in some aspects. Conclusion: The negative treatment-related impact of chemoradiation on short-term HRQL is less than that experienced with combination treatment including surgery. Patients preferring early recovery should consider definitive chemoradiation. Copyright © 2007 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd. [source]


Hepatic venous outflow reconstruction in adult living donor liver transplants without portal hypertension

CLINICAL TRANSPLANTATION, Issue 2 2004
Diego Bogetti
Abstract:, Graft congestion is one of the causes of poor graft function in segmental liver transplantation. Three factors are implicated in segmental graft congestion: graft size, hepatic venous outflow and portal inflow. The graft size must be matched to the body weight, which is conventionally done by using graft to body weight ratio. Hepatic blood outflow must be optimized by hepatic vein reconstruction, which can be complicated. High portal blood flow has been shown to be detrimental to small-for-size grafts. These factors are strictly connected to each other. They can all contribute to graft congestion and poor function, while one factor can compensate for the others and decrease congestion. Ideally, all the accessory veins should be reconstructed, if possible, to maximize the outflow. In the absence of portal hypertension and with an adequate sized graft, complex venous reconstruction may not be necessary. We present a case report of an adult living donor liver transplant with the favorable conditions of normal portal pressure and a large sized graft, but complicated by the presence of several accessory hepatic veins. A simple hepatic vein anastomosis was sufficient for adequate outflow and prompt graft function. [source]
