Geographic disparity: the dilemma of lower socioeconomic status,multiple listing,and death on the liver transplant waiting list

Due to the current regionally based allocation system, some patients list for and are transplanted away from home in regions with shorter waits and higher transplant rates. Of 147 included patients, 120 died waiting and 27 received transplants at outside centers during the study (32.5 months). Those transplanted elsewhere had higher median incomes than patients dying on the waitlist ($84 946 vs. $55 250, p = 0.0001). Those with median incomes <$60 244 were more likely to die than those with incomes >$60 244 (94% vs. 70%, RR: 1.35, 95% CI: 1.14–1.59). Patients with Medicaid were more likely to die waiting than those with other insurance (100% vs. 77%, RR: 1.30, 95% CI: 1.18–1.44). Our analysis demonstrates that those who died waiting were more likely to have lower incomes and Medicaid compared with those transplanted elsewhere. Even when we controlled for Medicaid status, patients who died waiting had lower incomes compared with those transplanted elsewhere. Increased organ sharing over geographically broader regions, as recommended by the Institute of Medicine in 1999, may reduce incentives for patients to travel to receive a liver and reduce inequities. Current efforts to address this disparity continue to fall short of the Institute of Medicine recommendations, United States Department of Health and Human Services regulations and the Final Rule.     

The Implementation of Cognitive Therapy in STAR*D

The Sequenced Treatment Alternatives to Relieve Depression (STAR*D) project will provide symptomatic and functional outcome data to evaluate the theoretical principles and clinical beliefs that currently guide the treatment of nonpsychotic major depression. Cognitive Therapy (CT) for depression has been chosen as a switch or augmentation treatment for patients who have failed an adequate trial of the antidepressant citalopram. We describe the rationale, organization, and role of CT in STAR*D. We discuss the issues involved in developing and implementing CT in a large, multisite, effectiveness study: therapist selection, training, certification, quality assurance, and post-training supervision. We conclude with a discussion of the implications of our implementation procedures on interpreting the results of the STAR*D study.     

Incidence and Risk Factors of Postoperative Urinary Retention and Bladder Catheterization in Patients Undergoing Fast-Track Total Joint Arthroplasty: A Prospective Observational Study on 371 Patients

Background

Postoperative urinary retention (POUR) appears to be a common complication in lower limb joint arthroplasty; however, reports on its incidence vary. There is no general consensus on its definition and there is no scientific evidence on treatment principles. We performed a prospective observational study to establish the incidence of POUR and its risk factors, including the preoperative postvoid residual urine volume and the perioperative fluid balance, in fast-track total joint arthroplasty (TJA). The preoperative residual urine volume and the perioperative fluid balance have not been studied in previous literature in the context of TJA and POUR.

Molecular diagnosis of kidney transplant failure based on urine

In light of the organ shortage, there is a great responsibility to assess postmortal organs for which procurement has been consented and to increase the life span of transplanted organs. The former responsibility has moved many centers to accept extended criteria organs. The latter responsibility requires an exact diagnosis and, if possible, omission of the harmful influence on the transplant. We report the course of a kidney transplant that showed a steady decline of function over a decade, displaying numerous cysts of different sizes. Clinical workup excluded the most frequent causes of chronic transplant failure. The filed allocation documents mentioned the donor’s disease of oral‐facial‐digital syndrome, a rare ciliopathy, which can also affect the kidney. Molecular diagnosis was performed by culturing donor tubular cells from the recipient´s urine more than 10 years after transplantation. Next‐generation panel sequencing with DNA from tubular urinary cells revealed a novel truncating mutation in OFD1, which sufficiently explains the features of the kidney transplants, also found in the second kidney allograft. Despite this severe donor disease, lifesaving transplantation with good long‐term outcome was enabled for 5 recipients.     

Success with plasmapheresis treatment for recurrent focal segmental glomerulosclerosis in pediatric renal transplant recipients

FSGS recurs in approximately 30% of transplanted kidneys and may lead to graft loss. We retrospectively examined the efficacy of early and intensive PP without additional IS in pediatric kidney transplant patients with recurrent FSGS at our center. Seven of 24 patients (29%) had nephrotic proteinuria and histologic evidence of FSGS recurrence within 1–5 days post‐transplantation. PP was initiated early after transplantation and initially performed daily until sustained decline in proteinuria. PP frequency was then individually tapered according to proteinuria. Recurrent FSGS in all seven patients responded to a four‐ to 32‐wk course of PP. Two of seven patients had a second recurrence of FSGS, and both recurrences remitted after an additional 3–6 wk of PP. Median observation period was 4.5 yr (0.8–16.3 yr). Complete remission of recurrent FSGS has been sustained in all seven patients, and all patients have stable graft function with recent plasma creatinine <1.5 mg/dL in six of seven patients. Most recent urine protein/creatinine is 0.13–0.61 mg/mg in six of seven patients. One patient has heavy proteinuria secondary to chronic allograft nephropathy 16 yr post‐transplant. Intensive and prolonged PP, when initiated early in the post‐operative period, is effective in treating recurrent FSGS and preventing graft loss without the use of additional immunosuppressants.     

PPARalpha governs glycerol metabolism

Glycerol, a product of adipose tissue lipolysis, is an important substrate for hepatic glucose synthesis. However, little is known about the regulation of hepatic glycerol metabolism. Here we show that several genes involved in the hepatic metabolism of glycerol, i.e., cytosolic and mitochondrial glycerol 3-phosphate dehydrogenase (GPDH), glycerol kinase, and glycerol transporters aquaporin 3 and 9, are upregulated by fasting in wild-type mice but not in mice lacking PPARalpha. Furthermore, expression of these genes was induced by the PPARalpha agonist Wy14643 in wild-type but not PPARalpha-null mice. In adipocytes, which express high levels of PPARgamma, expression of cytosolic GPDH was enhanced by PPARgamma and beta/delta agonists, while expression was decreased in PPARgamma(+/-) and PPARbeta/delta(-/-) mice. Transactivation, gel shift, and chromatin immunoprecipitation experiments demonstrated that cytosolic GPDH is a direct PPAR target gene. In line with a stimulating role of PPARalpha in hepatic glycerol utilization, administration of synthetic PPARalpha agonists in mice and humans decreased plasma glycerol. Finally, hepatic glucose production was decreased in PPARalpha-null mice simultaneously fasted and exposed to Wy14643, suggesting that the stimulatory effect of PPARalpha on gluconeogenic gene expression was translated at the functional level. Overall, these data indicate that PPARalpha directly governs glycerol metabolism in liver, whereas PPARgamma regulates glycerol metabolism in adipose tissue.
