Role of exposure with response prevention in cognitive,behavioral therapy for bulimia nervosa: Three-year follow-up results

INTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 2 2003
Frances A. Carter
Abstract Background Previous studies have not reported the longer-term outcome of exposure-based treatments for bulimia nervosa. The current study evaluated the 3-year outcome of a randomized clinical trial that compared the additive efficacy of exposure-based versus nonexposure-based behavioral treatments (BT) with a core of cognitive,behavior therapy (CBT). Methods One hundred thirteen women participated in the original treatment trial and attended a 3-year follow-up assessment. Eating disorder diagnoses and primary, secondary, and tertiary outcome measures were assessed. The impact of treatment completion on symptomatology and the stability of treatment effects over time were evaluated. Results At the 3-year follow-up, 85% of the sample had no current diagnosis of bulimia nervosa and 69% had no current eating disorder diagnoses of any sort. Failure to complete CBT was associated with inferior outcome. No clear advantages were evident for participants who completed BT in addition to CBT. For subjects who did complete both CBT and BT, outcome was mostly stable from posttreatment to follow-up. No differential effects were found for exposure versus nonexposure-based treatments at 3-year follow-up. Discussion The results of the current study compare favorably with other treatment outcome studies for bulimia nervosa and suggest that treatment gains are maintained after 3 years. © 2003 by Wiley Periodicals, Inc.

D-MELD, a Simple Predictor of Post Liver Transplant Mortality for Optimization of Donor/Recipient Matching

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 2 2009
J. B. Halldorson
Numerous donor and recipient risk factors interact to influence the probability of survival after liver transplantation. We developed a statistic, D-MELD, the product of donor age and preoperative MELD, calculated from laboratory values. Using the UNOS STAR national transplant data base, we analyzed survival for first liver transplant recipients with chronic liver failure from deceased after brain death donors. Preoperative D-MELD score effectively stratified posttransplant survival. Using a cutoff D-MELD score of 1600, we defined a subgroup of donor,recipient matches with significantly poorer short- and long-term outcomes as measured by survival and length of stay (LOS). Avoidance of D-MELD scores above 1600 improved results for subgroups of high-risk patients with donor age ,60 and those with preoperative MELD ,30. D-MELD ,1600 accurately predicted worse outcome in recipients with and without hepatitis C. There is significant regional variation in average D-MELD scores at transplant, however, regions with larger numbers of high D-MELD matches do not have higher survival rates. D-MELD is a simple, highly predictive tool for estimating outcomes after liver transplantation. This statistic could assist surgeons and their patients in making organ acceptance decisions. Applying D-MELD to liver allocation could eliminate many donor/recipient matches likely to have inferior outcome. [source]

Muscle strain injuries of the hindlimb in eight horses: diagnostic imaging, management and outcomes

AUSTRALIAN VETERINARY JOURNAL, Issue 8 2010
EA Walmsley
Objective To describe the clinical presentation, ultrasound findings, management and outcome in horses with muscle tear injuries of the hindlimbs. Design Retrospective case series Procedure Medical records of eight horses were reviewed and information on signalment, history, presenting complaint, physical examination findings and further diagnostic tests were recorded. Diagnosis of muscle injury was determined by the presence of abnormal ultrasound findings, compared with the contralateral limb, and, when required, nuclear scintigraphy. Follow-up information was obtained via telephone interviews with owners, trainers and referring veterinarians. Results Muscle tears causing lameness were identified in the middle gluteal (3), semitendinosus (1), semimembranosus (2) and gracilis (2) muscles. Tears were classified by ultrasound imaging as partial (6) or complete (2). The degree of lameness did not appear to be indicative of the extent of injury or of completion of healing. Long-term follow-up was available for seven horses and the outcome was favourable in six cases. Conclusions and clinical relevance Ultrasonography is useful in the diagnosis and assessment of moderate to severe muscle strain injuries. The prognosis appears to be favourable in most cases, although recurrence of injury and lameness can delay the return to athletic activity and an inferior outcome with persistent gait abnormality may occur.

Factors in older cadaveric organ donors impacting on renal allograft outcome

CLINICAL TRANSPLANTATION, Issue 1 2001
Deborah J Verran
Transplantation of renal allografts (RA) from older donors has become more common, despite conflicting data on outcome between reports from large series versus individual centres. Factors other than donor age per se may contribute to RA outcome. The outcome of RA procured from 114 older donors over 55 yr of age in NSW, between 1990 and 1997, was analysed. Corresponding donor factors, including demographics, medical history, inotrope use, major hypotension and findings at procurement, were also analysed. Of the potential RA, 8% were discarded and the remainder transplanted. Factors significantly associated with renal discard were pre-transplantation donation biopsy abnormality (p<0.001) and a history of cardiovascular (CV) disease in the donor (p<0.02). Donor aortorenal atherosclerosis (AS; p<0.09) and a donor age of 65 yr or older (p<0.08) were common in the discard group. The never function rate was 7.6% and was associated with a history of a discarded partner kidney (p<0.05). The delayed graft function rate was 33% and was associated with a history of donor CV disease. At a median follow up of 5 yr, the death censored allograft failure rate was 24%. Allograft failure was associated with a history of donor hypertension (p<0.05). Donor AS (p<0.7) tended to have been more common in the allograft failure group. A number of cadaveric organ donor factors documented at procurement may be associated with inferior outcome of RA. These include biopsy abnormality, history of donor CV disease and history of donor hypertension. A donor age of 65 yr or older or significant visible aortorenal AS may also be factors. This retrospective review of kidneys procured from 114 older cadaveric organ donors identifies factors apart from donor age, which may have a negative impact on both allograft utilisation and outcome. Theses factors include renal biopsy abnormality, history of donor CV disease, discard of a partner kidney and donor hypertension. Visible AS in the donor aorta documented at renal procurement may also be a factor. [source]

PARTICIPATION IN INTERNATIONAL ENVIRONMENTAL AGREEMENTS: THE ROLE OF TIMING AND REGULATION

NATURAL RESOURCE MODELING, Issue 2 2006
MICHAEL FINUS
ABSTRACT. We analyze the formation of self-enforcing international environmental agreements under the assumption that countries announce their participation either simultaneously or sequentially. It is shown that a sequential formation process opens up possibilities for strategic behavior of countries that may lead to inferior outcomes in terms of global abatement and welfare. We then analyze whether and under which conditions a regulator like an international organization, even without enforcement power, can improve upon globally suboptimal outcomes through coordination and moderation, given that recommendations must be Pareto-improving to all parties.

Changing trends in pediatric transplantation: 2001 Annual Report of the North American Pediatric Renal Transplant Cooperative Study

PEDIATRIC TRANSPLANTATION, Issue 4 2003
Mark R. Benfield
This cooperative group now includes over 150 participating medical centers in the United States, Canada, Mexico, and Costa Rica. This report covers the years from 1987 through 2001 and includes data on 7545 renal transplants in 6878 patients. This report demonstrates changing trends in many areas of pediatric transplantation including increasing numbers of African American and Hispanic children receiving transplantation, remarkable improvements in the rate of acute rejection, rejection reversal, and short- and long-term allograft survival. In the most recent cohorts of patients, we now see that 1-yr allograft survival is no different in cadaver donor compared to living donor recipients and in infants compared to all other age groups. However, this analysis also reveals areas of continued challenges including inferior outcomes in African American and adolescent populations, chronic rejection, and the adverse effects of immunosuppression.

American Society of Transplant Surgeons Transplant Center Outcomes Requirements,A Threat to Innovation

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 6 2009
M. M. Abecassis
The transplant center regulations recently published by the Centers for Medicare and Medicaid (CMS) mandate that observed program-specific survival outcomes to fall within expected risk-adjusted outcomes. Meeting these outcomes is essential to continued participation in the Medicare program. Both donor and recipient variables not considered in current risk adjustment models can result in inferior outcomes and therefore may cause an overestimation of transplant center expected performance, precluding participation in the federally funded Medicare program. We reviewed the most recent four reporting periods published by the Scientific Registry for Transplant Recipients on their public website. We identified kidney, liver and heart transplant programs that were flagged for having outcomes statistically lower than expected as well as those that failed to meet CMS criteria. We also analyzed whether center volumes correlated with outcomes in these centers. We highlight the need for mitigating factors that could justify inferior outcomes under specific circumstances. Failure to reach consensus on such a mechanism for appeal may result in risk-averse behavior by transplant centers with respect to innovation and therefore hamper the ability to advance the field of transplantation. We propose a methodology that may address this emerging dilemma. [source]

Solving the Organ Shortage Crisis: The 7th Annual American Society of Transplant Surgeons' State-of-the-Art Winter Symposium

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 4 2008
E. A. Pomfret
The 2007 American Society of Transplant Surgeons' (ASTS) State-of-the-Art Winter Symposium entitled, ,Solving the Organ Shortage Crisis' explored ways to increase the supply of donor organs to meet the challenge of increasing waiting lists and deaths while awaiting transplantation. While the increasing use of organs previously considered marginal, such as those from expanded criteria donors (ECD) or donors after cardiac death (DCD) has increased the number of transplants from deceased donors, these transplants are often associated with inferior outcomes and higher costs. The need remains for innovative ways to increase both deceased and living donor transplants. In addition to increasing ECD and DCD utilization, increasing use of deceased donors with certain types of infections such as Hepatitis B and C, and increasing use of living donor liver, lung and intestinal transplants may also augment the organ supply. The extent by which donors may be offered incentives for donation, and the practical, ethical and legal implications of compensating organ donors were also debated. The expanded use of nonstandard organs raises potential ethical considerations about appropriate recipient selection, informed consent and concerns that the current regulatory environment discourages and penalizes these efforts.
