Cardiac transplantation--first year experience in a community hospital: a three year follow-up

This is a report of ten consecutive patients with end-stage cardiac disease treated with orthotopic cardiac transplantation in a community hospital, during the first year of its heart transplantation program. All patients were followed for a minimum of 33 months and a maximum of 45 months with 100% survival at two years and 90% at three years. All survivors are presently in N.Y.H.A. Class I or II. The entire group of patients received the same triple immunosuppressive therapy. The incidence of infection and rejection during the first three months post-transplantation was 0.3 and 0.6 episodes per patient respectively. Every patient developed some degree of deterioration in renal function and 80% of the patients now receive treatment for systemic hypertension. The in-hospital institution cost for the transplant admission varied from $25,084 to $74,164. To date, 30 patients have undergone heart transplantation in our program and 26 are long-term successes. This study again proves that renal insufficiency and hypertension remain the major side effects of Cyclosporine therapy. We further conclude from our experience that cardiac transplantation can be successfully and cost effectively performed in a community hospital even with a somewhat lower caseload.     

Donation after cardiac death liver transplantation is associated with increased risk of end‐stage renal disease

Limited organ supply has led to greater use of liver allografts with higher donor risk indices (DRI) and/or donated after cardiac death (DCD). DCD status is associated with acute kidney injury after liver transplantation; however, less is known about the association between donor quality and end‐stage renal disease (ESRD). Using SRTR data, we assembled a cohort of liver transplant recipients from 2/2002 to 12/2010. We fit multivariable Cox regression models for ESRD. Model 1 included total DRI; model 2 included components of DRI, including DCD, as separate variables. Forty thousand four hundred and sixty‐three liver transplant recipients were included. Median DRI was 1.40 (IQR 1.14, 1.72); 1822 (5%) received DCD livers. During median follow‐up of 3.93 years, ESRD occurred in 2008 (5%) and death in 11 075 (27%) subjects. There was a stepwise increase in ESRD risk with higher DRI (DRI ≥1.14 and <1.40: HR 1.17, P = 0.06; DRI ≥1.40 and <1.72: HR 1.29, P = 0.003; DRI ≥1.72: HR 1.39, P < 0.001, compared with DRI <1.14). Adjusting for DRI components separately, DCD status was most strongly associated with ESRD (HR 1.40, P = 0.008). Higher DRI is associated with ESRD after liver transplantation, driven in part by DCD status. Donor quality is an important predictor of long‐term renal outcomes in liver transplant recipients.     

Diagnosis and Treatment of Multiple Sclerosis

A most important clinical decision in the differential diagnosis of jaundice is whether the patient has a medical disease or one amenable to surgery.

Jaundice is rarely an emergency condition; an unnecessary operation on a patient with acute hepatitis greatly increases the mortality, whereas failure to diagnose a surgical lesion early does not lessen the benefits of operation.     

Psychosocial and Spiritual Care in Hospice: Differences Between Nursing,Social Work,and Clergy

A chart review of the most recent home visits from nursing, social work, and clergy to 37 home hospice patients indicated that all but two psychosocial and spiritual issues examined were addressed by hospice staff on home visits. Spirituality and, secondly, death anxiety were the most frequently discussed variables. Clergy addressed more spiritual issues than the other two professions, and social work addressed more psychosocial issues than the other two professions. These findings underscore the important roles that clergy and social work play on the hospice team, and imply that hospice should make a renewed commitment to psychosocial and spiritual care.

Memory functioning in post‐traumatic stress disorder: objective findings versus subjective complaints

Although memory complaints are common in post‐traumatic stress disorder (PTSD), the only published study of objective and subjective memory in PTSD by Roca and Freeman indicates that subjective complaints may not accurately reflect objective performance. The present study examined memory in 21 PTSD patients, 20 combat controls and 23 non‐combat controls using two objective memory measures (Rey Auditory Verbal Learning Test; Backward Digit Span) and one subjective measure (Memory Functioning Questionnaire). Analysis of variances (ANOVAs) and analysis of co‐variances generally did not reveal group differences for objective memory performance. For subjective memory complaints, ANOVAs indicated group differences; PTSD participants reported more memory problems than controls. These differences disappeared, however, when depression was included as a covariate. Also, we provide some preliminary evidence that depression may mediate the relationship between PTSD symptomatology and subjective memory complaints. Findings suggest that reductions in depressive symptomatology in PTSD may be associated with decreased subjective memory complaints. Copyright © 2010 John Wiley & Sons, Ltd.     

Screening for sickle trait among potential live kidney donors: policies and practices in US transplant centers.

Sickle cell trait is common in the United States (US) and associated with abnormalities of renal function. Little is known, however, about the potential risk of sickle cell trait to live kidney donors. Using an original questionnaire, we assessed the policies and practices of US renal transplant centers with regard to screening for sickle trait among potential live kidney donors. Fifty-four percent (137/252) of centers responded. Eighty-three percent (113/137) of transplant centers had no policy to screen donors for sickle trait. Thirty-four percent (46/135) of centers reported actually screening donors for sickle trait in practice. Thirty-seven percent (39/105) of centers reported excluding donors with sickle trait always or most of the time. High volume centers (>100 live donor transplants/year) were more likely to screen for sickle trait (Fisher's exact, P = 0.03), but not more likely to exclude potential donors with sickle trait from donating. Most US renal transplant centers do not screen donors for sickle trait. Wide variation is evident in center practice regarding exclusion of donors on the basis of sickle trait. Research into the potential impact of sickle trait on renal function after donation is needed to guide transplant clinicians.     

Talactoferrin alfa, a recombinant human lactoferrin promotes healing of diabetic neuropathic ulcers: a phase 1/2 clinical study

BACKGROUND: Talactoferrin alfa, a recombinant form of human lactoferrin, is a novel immunomodulatory protein with demonstrated ulcer healing properties in animal models. METHODS: A phase 1/2 clinical study was conducted at 7 clinical sites to determine if talactoferrin can improve wound healing in diabetic patients with foot ulceration. Fifty-five patients with diabetic neuropathic foot ulcers participated in this 2-phase study. In phase 1, groups of 3 patients each received open-label 1%, 2.5%, or 8.5% talactoferrin gel twice daily, in a sequential design, to their ulcer for 30 days. No drug-related adverse events were found at any dose level. Phase 2 was a randomized, placebo-controlled, single-blind study of 2.5% and 8.5% gels, with patients equally divided between the 3 groups. In combination with good wound care, treatment was administered topically twice daily to the ulcers for 12 weeks. The primary endpoint was the incidence of > or = 75% healing (relative to baseline size). RESULTS: The study, which in phase 2 was powered to detect a difference between the placebo and combined talactoferrin arms with P < .1, met the primary objective. The groups receiving the 2.5% (n = 15) and 8.5% (n = 15) gels had twice the incidence of > or = 75% reduction in ulcer size compared with the placebo group (n = 16): 47%, 53%, and 25%, respectively. On an intent-to-treat basis, the combination of the 2 active groups when compared with the placebo group showed a strong trend toward statistical significance (P = .09). There were no talactoferrin-related adverse events or laboratory abnormalities. CONCLUSIONS: Topical talactoferrin appears to be safe and well tolerated and improves healing of diabetic neuropathic ulcers.     

Massive diarrhea in Legionella micdadei pneumonitis

Mild diarrhea of poorly documented volume is common early in the course of Legionella infection. We report massive diarrhea of 1.8 to 3 liters per day in a patient with pneumonia in whom Legionella micdadei was isolated from pleural fluid and infection was confirmed serologically. The large volume of diarrhea, not previously associated with Legionella infection, remained unexplained despite clinical evaluation and postmortem study of the gastrointestinal tract. This case expands the clinical spectrum of Legionnaires' disease to include massive diarrhea, which in our patient constituted the chief complaint.
