Introduction: The safety and liver utilization with prerecovery liver biopsy (PLB) in extended criteria liver donors are unclear. Methods: We conducted a retrospective cohort study in 1323 brain death donors (PLB=496) from three organ procurement organizations (OPOs). Outcomes were complications, preemption of liver recovery (PLR) and livers transplanted (LT). Additional analyses included liver only and propensity score-matched multiorgan donor subgroups. Results: PLB donors were older (57yrs vs 53yrs, p

Animal models and observational human data indicate that complement, including C5a, pathogenically participates in ischemia reperfusion (IR) injury that manifests as delayed graft function (DGF) following deceased donor kidney transplantation. We report on the safety/efficacy of anti-C5 monoclonal antibody eculizumab (Ecu) administered in the operating room prior to reperfusion, to prevent DGF in recipients of deceased donor kidney transplants in two related, investigator-sponsored, randomized controlled trials. Eight recipients from a single center were enrolled in a pilot study that led to a 19-subject multicenter trial. Together, 27 deceased donor kidney transplant recipients, 16 Ecu-treated and 11 controls, were treated with rabbit antithymocyte globulin, tacrolimus, mycophenolate mofetil with or without glucocorticoids, and followed for 6 months. Data analysis showed no epidemiological or transplant-related differences between study arms. Ecu was well tolerated with a similar severe adverse event incidence between groups. The DGF rate did not differ between Ecu-treated (44%) and control (45%, P = 1.0) subjects. Serum creatinine reduction in the first week after transplantation, and graft function up to 180-days post-transplant, were also similar. Ecu administration was safe but did not reduce the rate of DGF in a high-risk population of deceased donor recipients.

The premise that lower TAC trough levels are associated with subsequently higher first BPAR risk during the first 12 mo post-transplant was recently questioned. Using our prospectively followed cohort of 528 adult, primary kidney transplant recipients (pooled across four randomized trials) who received reduced TAC dosing plus an IMPDH inhibitor, TAC trough levels measured at seven time points, 7, 14 days, 1, 2, 3, 6 and 9 months post-transplant, were utilized along with Cox's model to determine the multivariable significance of TAC level(t) (a continuous time-dependent covariate equaling the most recently measured TAC level prior to time t) on the hazard rate of developing first BPAR during the first 12 months post-transplant. The percentage developing BPAR during the first 12 months post-transplant was 10.2% (54/528). In univariable analysis, lower TAC level(t) was associated with a significantly higher BPAR rate (P = 0.00006), and its significance was maintained even after controlling for 2 significant baseline predictors (African-American/Hispanic Recipient and Developed DGF) in Cox's model (multivariable P = 0.0003). Use of a cutpoint, TAC level(t)

Accurate and reliable assessment tools are needed in transplantation. The objective of this prospective, multicenter study was to determine the associations of the alpha and pi iso-enzymes of glutathione S-transferase (GST), measured from perfusate solution at the start and end (base and post) of kidney allograft machine perfusion, with subsequent delayed graft function (DGF). We also compared GST iso-enzyme perfusate levels from discarded versus transplanted kidneys. A total of 428 kidneys were linked to outcomes as recorded by the United Network of Organ Sharing. DGF, defined as any dialysis in the first week of transplant, occurred in 141 recipients (32%). Alpha and pi-GST levels significantly increased during machine perfusion. The adjusted relative risks (95% confidence interval) of DGF with each log-unit increase in base and post pi-GST were 1.14 (1.0-1.28) and 1.33 (1.02-1.72), respectively. Alpha-GST was not independently associated with DGF. There were no significant differences in GST values between discarded and transplanted kidneys, though renal resistance was significantly higher in discarded kidneys. We found pi-GST at the end of machine perfusion to be independently associated with DGF. Further studies should elucidate the utility of GST for identifying injured kidneys with regard to organ allocation, discard and recipient management decisions.

Background and objectives The influence of deceased-donor AKI on post-transplant outcomes is poorly understood. The few published studies about deceased-donor preimplant biopsy have reported conflicting results regarding associations between AKI and recipient outcomes. Design, setting, participants, & measurements This multicenter study aimed to evaluate associations between deceased-donor biopsy reports of acute tubular necrosis (ATN) and delayed graft function (DGF), and secondarily for death-censored graft failure, first adjusting for the kidney donor risk index and then stratifying by donation after cardiac death (DCD) status. Results Between March 2010 and April 2012, 651 kidneys (369 donors, 4 organ procurement organizations) were biopsied and subsequently transplanted, with ATN reported in 110 (17%). There were 262 recipients (40%) who experienced DGF and 38 (6%) who experienced graft failure. DGF occurred in 45% of kidneys with reported ATN compared with 39% without ATN ( P =0.31) resulting in a relative risk (RR) of 1.13 (95% confidence interval [95% CI], 0.9 to 1.43) and a kidney donor risk index–adjusted RR of 1.11 (95% CI, 0.88 to 1.41). There was no significant difference in graft failure for kidneys with versus without ATN (8% versus 5%). In stratified analyses, the adjusted RR for DGF with ATN was 0.97 (95% CI, 0.7 to 1.34) for non-DCD kidneys and 1.59 (95% CI, 1.23 to 2.06) for DCD kidneys ( P =0.02 for the interaction between ATN and DCD on the development of DGF). Conclusions Despite a modest association with DGF for DCD kidneys, this study reveals no significant associations overall between preimplant biopsy-reported ATN and the outcomes of DGF or graft failure. The potential benefit of more rigorous ATN reporting is unclear, but these findings provide little evidence to suggest that current ATN reports are useful for predicting graft outcomes or deciding to accept or reject allograft offers.

This study examined whether patient symptoms and relatives' affective behavior, when expressed during directly observed family interactions, are associated with the short-term course of bipolar disorder. Twenty-seven bipolar patients and their relatives participated in two 10-minute family interactions when patients were discharged after a manic episode. Results indicated that patients who showed high levels of odd and grandiose thinking during the interactions were more likely to relapse during a 9-month followup period than patients who did not show these symptoms during the family discussions. Relapse was also associated with high rates of harshly critical and directly supportive statements by relatives. Patients' odd thinking and relatives' harsh criticism were significantly more likely to be correlated when patients relapsed (r = .53) than when they did not relapse (r = .12). Results suggest that bipolar patients who show increased signs of residual symptomatology during family transactions during the post-hospital period are at increased relapse risk. The data also suggest that relatives of relapsing patients cope with these symptoms by increasing both positive and negative affective behaviors. Moreover, a bidirectional, interactional relationship between patients' symptoms and relatives' coping style seems to capture best the role of the family in predicting relapse in bipolar disorder.

Enhancement of renal allograft function and survival in an era where expanded criteria donors are increasingly used requires validated selection criteria. The goal of this retrospective study was to evaluate the significance of pretransplant donor and allograft parameters to identify risk factors that can be used in a model to predict 1-year allograft outcomes. Donor demographic factors, donor type, and allograft parameters such as biopsy results and machine-measured renal resistance were correlated with 1-year graft outcome. The Kaplan-Meier method was used to estimate graft survival using the categorical predictors of donor type, donor age, and machine-measured renal resistance at 1.5, 3, and 5 hours. The log-rank test was used to test the difference in survival curves between cohorts. The Cox regression analysis was used to estimate hazard ratios for machine-measured renal resistance, donor age, donor terminal creatinine level, donor's estimated glomerular filtration rate, cold ischemia time, and percent glomerulosclerosis. The data show that machine-measured renal resistance at 3 and 5 hours has a statistically significant inverse relationship to 1-year graft survival. All other risk factors had no correlation with 1-year graft survival. The machine-measured renal resistance at 3 hours is the earliest significant predictor of 1-year allograft outcome.

The disparity between organ supply and demand has necessitated more aggressive use of livers from extended criteria donors. Organ sharing between donor service areas and transplant centers in other regions is common. Confidence in the graft quality is greatly improved with a digital image taken in conjunction with the recovery surgeon's report and biopsy data. Three cases in which digital images of various levels of quality allowed the recipient's surgery to proceed, minimized the cold ischemia time, and yielded excellent outcomes are described. Another case in which a picture was not available and the liver was discarded after importation is also presented for comparison.

There are multiple possible causes of ascites in patients with end-stage renal disease on hemodialysis therapy. In this report, we describe a patient with chronic hepatitis C infection who presented with refractory inflammatory ascites, along with cachexia, hypoalbuminemia, and erythropoietin resistance associated with the chronic inflammatory state induced by a failed kidney transplant. Evaluation showed only mild hepatic fibrosis, absence of portal hypertension, and no other identifiable cause of the ascites. Furthermore, the inflammatory ascites did not respond to antibiotic therapy, but promptly resolved, along with the other manifestations of the chronic inflammatory state, after transplant nephrectomy. This report describes a novel cause for refractory inflammatory ascites in a patient with a failed kidney transplant and emphasizes the importance of transplant nephrectomy.

In current practice, human immunodeficiency virus-infected (HIV(+) ) candidates with CD4 >200 cells/mm(3) are eligible for kidney transplantation; however, the optimal pretransplant CD4 count above this threshold remains to be defined. We evaluated clinical outcomes in patients with baseline CD4 >350 and

Background: Understanding the relative contributions of baseline demographics and immunosuppressive therapy on NODAT risk may help in developing preventive strategies. Methods: Using our prospectively followed cohort of 481 adult, primary kidney transplant recipients without pre-transplant diabetes, we determined the significant baseline predictors for the hazard rate of developing NODAT via Cox stepwise regression. The multivariable influence of first BPAR (defined as a time-dependent covariate) was also tested. Results: Median follow-up was 57 mo post-transplant; the overall percentage who developed NODAT was 22.5% (108/481). Four baseline predictors of a greater NODAT hazard rate were found (by order of selection): higher BMI (p < 0.000001), planned maintenance with SRL (p = 0.0003), non-white recipient (p = 0.0004), and older recipient age (p = 0.0004). Approximately one-half of the 106 patients in the highest demographic risk category (BMI ≥25 kg/m 2 , non-white race, and age at transplant ≥40 yr) developed NODAT; actuarial NODAT risk ranged from 10% to 30% in the lower demographic risk categories. First BPAR was also associated with significantly higher NODAT in multivariable analysis (p = 0.02)—the highly elevated NODAT rate observed during the first few months post-transplant and following first BPAR appears to demonstrate the diabetogenic effect of using high-dose (intravenous) corticosteroids. Conclusions: The disturbingly high NODAT rate found among patients having multiple demographic risk factors is still an important problem that awaits a better solution.

ationally, student interest in pursuit of a general surgery resdency steadily dropped from the early 1980s through the first art of this decade. General surgery was the first-choice resiency for 10.7% of U.S. senior medical students in 1984, but nly 4.7% in 2002. This diminishing interest finally maniested itself in the National Resident Matching Program in 001, when 68 (6.5%) general surgery residency positions went nfilled. In 2002, U.S. graduates comprised less than 80% of all atched applicants for the first time and 58 (5.5%) positions ere unfilled. Analysis of these data led to projections of further eclines in the number and quality of U.S. students matching o general surgery residencies, with serious implications for the ation. Published data suggest that, given an aging population, he United States will face an absolute shortage of general sureons as soon as 2010, with difficulty in attracting and retaining urgeons in some regions of the country already apparent. The past decade has seen many publications about medical tudent career preferences and the decline of interest in general urgery. Data demonstrate that perceived resident and attendng surgeon lifestyle are the major deterrents to medical stuents considering surgery as a career option. Students specifcally associate general surgery with irregular schedules, limited amily and leisure time, and high levels of stress. They cite anageable work hours as more important than income, and hey identify “controllable lifestyle” as their highest priority. his evolving attitude, combined with perceptions of surgery as particularly demanding field, underlie the decline of interest n general surgery residency programs.

The term thrombotic microangiopathy (TMA) hasbeenapplied toa diversegroup of conditionsthat sharethe common pathomechanism of endothelial damage.TMA is a recognized complication of solid organtransplantation.ThemajorityofcasesrepresentdenovoTMA, which occurs in 02.8–3.5% of renal transplantrecipients and is associated with a 22% rate of graftloss [1]. The rate of graft loss is strongly influencedby whether the TMA is systemic or renal limited (38vs 0% graft loss, respectively) [1].Treatment with calcineurin inhibitors (CNIs) is awell-established risk factor for the development of denovoTMA.Arecent,largeanalysisoftheUnitedStatesRenal Data System (USRDS) and Medicare claimsidentified multiple additional risk factors includingyounger recipient age, older donor age, female genderof the recipient, longer duration of dialysis before tran-splantation, previous renal transplant, delayed graftfunction (DGF), allograft rejection, increased peakpanel-reactive antibody, and treatment with sirolimus(SRL) [2]. Anti-cardiolipin antibody seropositivity,often in the setting of chronic hepatitis C virus infec-tion, is an additional risk factor for de novo TMA [3].SRL (rapamycin) is an immunosuppressive agentcommonly administered to renal transplant recipients.SRL may be used in combination with a CNI or as analternative agent. A recent, large trial has shown thatSRL facilitates early CNI withdrawal and that thisregimen is associated with less long-term nephrotox-icity [4]. The most frequently reported side effects ofSRL are thrombocytopenia, leukopenia, hypertriglyc-eridaemia and hypercholesterolaemia [5].SRL has a similar mechanism of action to the CNIs.Cyclosporin (CSA), tacrolimus (TAC) and SRL allproduce their immunosuppressive effect by binding tocytoplasmic proteins called immunophilins that modifyimmune function. CSA binds cyclophilin, and TACbinds FK-binding protein 12 (FKBP12); these com-plexes in turn inhibit calcineurin, a calcium-dependentphosphatase required for interleukin-2 production andprogression of T cells from the G to G

Hepatic ischemia/reperfusion (I/R) injury associated with liver transplantation and hepatic resection is characterized by hepatocellular damage and a deleterious inflammatory response. In this study, we examined whether receptor for advanced glycation end product (RAGE) activation is linked to mechanisms accentuating inflammation on I/R in a murine model of total hepatic ischemia. Animals treated with soluble RAGE (sRAGE), the extracellular ligand-binding domain of RAGE, displayed increased survival after total hepatic I/R compared with vehicle treatment. TUNEL assay and histologic analysis revealed that blockade of RAGE was highly protective against hepatocellular death and necrosis on I/R; in parallel, proliferating cell nuclear antigen was enhanced in livers of mice treated with sRAGE. Rapid activation of p38, p44/42, stress-activated protein kinase and c-Jun N-terminal kinase mitogen-activated protein kinases, signal transducer and activator of transcription-3, and nuclear translocation of activator protein-1 was evident at early times on I/R. In the remnants of sRAGE-treated livers, however, activation of each of these signaling and transcription factor pathways was strikingly decreased. sRAGE-treated remnants displayed enhanced activation of nuclear factor kappaB, in parallel with increased transcripts for the proregenerative cytokine, tumor necrosis factor-alpha. In conclusion, these data suggest that RAGE modulates hepatic I/R injury, at least in part by activation of key signaling pathways linked to proinflammatory and cell death-promoting responses. We propose that blockade of this pathway may represent a novel strategy to attenuate injury in hepatic I/R and to facilitate regeneration.

Over the past decade we have reported excellent outcomes in pediatric living-donor liver transplantation (LDLT) with recipient survival exceeding 90%. Principles established in these patients were extended to LDLT in adults. To compare outcomes in donors and recipients between adult and pediatric LDLT in a single center, we reviewed patient records of 45 LDLT performed between 1/98 and 2/01: 23 adult LDLT (54 +/- 6.5 yr) and 22 pediatric LDLT (33.7 +/- 53.5 months). Preoperative liver function was worse in adults (International Normalized Ratio [INR] 1.5 +/- 0.4 vs. INR 1.2 +/- 0.5; p = 0.032). 4 adults (17%) met criteria for status 1 or 2A. Only 1 child was transplanted urgently. Analysis included descriptive statistics and Kaplan-Meier estimation. Donor mortality was 0% with 1 re-exploration, 2.4%. Median hospital stay (LOS) was 6.0 days (range, 4-12 days). Donor morbidity and LOS did not differ by sex, extent of hepatectomy, or adult and pediatric LDLT ( p = 0.49). In contrast, recipient outcomes were worse for adults. Adult 1 year graft survival was 65% (3 retransplants [ReTx], 5 deaths) vs. 91% for children (1 ReTx, 1 death) p = 0.02. Graft losses in adults were due to sepsis (n = 3), small for size (n = 2), suicide, and hepatic artery thrombosis (HAT), whereas in children graft losses were due to portal thrombosis and total parenteral nutrition (TPN) liver failure. Biliary leaks occurred in 22% of adults and 9% of children. Hepatic vein obstruction occurred in 17% of adults and in none of the children. Median LOS was comparable (adult, 16.5 days (range, 7-149 days); child, 17 days (range, 10-56 days), p = 0.2). Graft function (total bilirubin (TBili) < 5mg/dl, INR < 1.2, aspartate aminotransferase (AST) < 100 U/l) normalizing by day 4 in children and by day 14 in adults. Adults fared worse, with an array of problems not seen in children, in particular, hepatic vein obstruction and small-for-size syndrome. Biliary leaks were diagnosed later in adults and were lethal in 3 cases; this was later avoided with biliary drainage in adult recipients. Finally, use of LDLT in decompensated adults led to death in 3 of 4 patients, and should be restricted to elective use.

Recently hospitalized bipolar, manic patients (N = 53) were randomly assigned to a 9-month, manual-based, family-focused psychoeducational therapy (n = 28) or to an individually focused patient treatment (n = 25). All patients received concurrent treatment with mood-stabilizing medications. Structured follow-up assessments were conducted at 3-month intervals for a 1-year period ofactive treatment and a 1-year period of posttreatment follow-up. Compared with patients in individual therapy, those in family-focused treatment were less likely to be rehospitalized during the 2-year study period. Patients in family treatment also experienced fewer mood disorder relapses over the 2 years, although they did not differ from patients in individual treatment in their likelihood of a first relapse. Results suggest that family psychoeducational treatment is a useful adjunct to pharmacotherapy in decreasing the risk of relapse and hospitalization frequently associated with bipolar disorder.

Studies have reported that certain measures of intrafamilial transactions are associated with an increased risk both for the initial onset of schizophrenia and for its recurrence following the initial episode of disorder. Two of the most studied of these are communication deviance (CD), a measure of subclinical thought disorder expressed in speech, and expressed emotion (EE), defined as notable attitudes of criticism and/or emotional overinvolvement manifested in a semistructured interview. A previous study (Goldstein et al. 1992) examined whether these two measures were associated with the presence of a diagnosable psychiatric disorder in the biological parents of recent-onset schizophrenia patients. In general, they were not. The present study went one step further. It examined whether these same measures were correlated with family history of schizophrenia or affective disorder in the biological parents and siblings of these same parents. High EE was not associated with a greater family history of schizophrenia spectrum disorders among the parent's parents and siblings but was unexpectedly found to be inversely associated with familial affective disorders. In contrast, CD was associated with a family history of schizophrenia spectrum disorders among the parent's parents and siblings. The findings are consistent with the possibility that CD may be an indicator of a genetic vulnerability factor for schizophrenia.

To better understand the implications of new-onset diabetes after transplant (NODAT), we used our prospectively followed cohort of 628 adult primary kidney transplant recipients to determine the prognostic impact of pretransplant diabetes and NODAT. The study cohort consisted of all participants in four randomised immunosuppression trials performed at our centre since May 2000. For each cause-specific hazard analysed, Cox stepwise regression was used to determine a multivariable model of significant baseline predictors; the multivariable influence of having pretransplant diabetes and NODAT (t) (the latter defined as a zero-one, time-dependent covariate) was subsequently tested. Similar analyses of estimated glomerular filtration rate (eGFR) at 36 and 60 months post transplant were performed using stepwise linear regression. Finally, a repeated measures analysis of mean HbA1c as a function of diabetes category (pretransplant diabetes vs NODAT) and randomised trial (first to fourth) was performed. Median follow-up was 56 months post transplant. Patients with pretransplant diabetes comprised 23.4% (147/628), and 22.5% (108/481) of the remaining patients developed NODAT. Pretransplant diabetes had no prognostic influence on first biopsy-proven acute rejection and death-censored graft failure hazard rates, nor on eGFR, but was associated with significantly higher rates of death with a functioning graft (DWFG) (p = 0.003), DWFG due to a cardiovascular event (p = 0.005) and infection that required hospitalisation (p = 0.03). NODAT (t) had no unfavourable impact on any of these hazard rates nor on eGFR, with actuarial freedom from DWFG remaining at over 90% among patients in pre- and post-NODAT states at 72 months post transplant/NODAT. Mean HbA1c for patients in the first to fourth randomised trials, averaged across diabetes category, decreased by trial (7.28%, 6.92%, 6.87% and 6.64% [56.1, 52.1, 51.6 and 49.1 mmol/mol], respectively; p = 0.02). Less-than-expected post-NODAT risk for graft loss and death may exist in the current climate of tighter glucose monitoring post transplant.

Culture is widely thought to influence the form, content, and extent of symptoms experienced and expressed by the mentally ill. However, little is known about how specific cultural groups differ in their symptomatic presentation of mental illness. Using data derived from the Present State Exam, the current study compared 63 Anglo-American and 53 Mexican-American patients with schizophrenia on ten psychiatric symptoms. A series of logistic regressions offered several interesting findings. For instance, as hypothesized, Mexican-American patients were more likely to report physical symptoms than their Anglo-American counterparts. Also in line with expectations, Anglo-American patients reported experiencing a greater frequency of several psychiatric symptoms such as persecutory delusions, nervous tension, and blunted affect. Results from this study suggest that the presentation of even a very biologically determined disorder such as schizophrenia can be shaped by sociocultural factors. Specific aspects of Anglo-American and Latino cultures that may influence symptom patterns in patients suffering from schizophrenia are discussed.

Sustained virological response SVR is defined as undetectable HCV RNA in plasma 6 months after therapy has been discontinued. Relapse or re-emergence of viremia after SVR is rare. We report two patients that relapsed when immune suppressive therapy was given within a few weeks of achieving SVR. Patient 1 received prednisone for bronchitis and patient 2 relapsed soon after immune suppression was started post renal transplantation. These data suggest that the early phase of SVR might be associated with incomplete protective immunity. They suggest that sterilizing immunity with complete elimination of virus is unlikely. The cases also caution against the use of immune suppressive therapy in the immediate aftermath of SVR.

This study examined the relation between the presence of depressive symptoms in schizophrenic patients with a recent first psychotic episode and affective disorders among their relatives.Data on depressive symptoms in 70 patients with schizophrenia diagnosed according to the DSM-III-R criteria, who had had a recent first psychotic episode, and psychiatric diagnostic information on 293 of their first-degree and 674 of their second-degree relatives were collected. Depressive symptoms in the schizophrenic probands were examined at the index psychotic episode (at study entry) and systematically over a 1-year follow-through period. The majority of first-degree family members were interviewed in person with the use of semistructured diagnostic interviews.The linear regression findings confirmed the hypothesis that depressive symptoms in the early course of schizophrenia are associated with a family history of unipolar affective illness.Because depression in the patients was associated with a family history of depression, this suggests that depression in schizophrenia is not solely either a reaction to having had a psychotic episode or part of the recovery process. The findings are consistent with a model in which a familial genetic liability to affective disorder, when present, is viewed a s exerting a modifying influence on the patient's schizophrenic illness to increase expression of depressive symptoms.

BackgroundPrevious research has generally found that variations in relatives' affective attitudes (expressed emotion; EE) towards a schizophrenic family member could not be accounted for by differences in the severity or form of the patient's symptomatology. These findings have been based on clinicians' ratings of psychopathology in patients.MethodTo approach the question from a different perspective, videotaped interactions between a patient and family members, obtained four to five weeks after hospital discharge, were coded for subclinical signs of psychopathology expressed by the patient. The Behavioral Subclinical Rating Scale (BSRS) was developed to compare subclinical levels of non-verbal and paralinguistic symptoms expressed by patients from both high- and low-EE families.ResultsHighly significant differences were found in the BSRS data. Patients from high-EE families showed more hostile and unusual behaviour with relatives than those from low-EE homes, who, in contrast, showed more anxious behaviour.ConclusionThese data suggest that a complex transactional model is necessary to understand how family attitudes evolve during the course of a relatives' schizophrenic disorder.

Aging, higher prevalence of diabetes, worsening obesity, and hyperglycemia among potential donors increase the likelihood that pancreata will be declined by transplant centers. Hemoglobin A1c testing, also known as glycated hemoglobin testing, identifies a donor's average blood glucose concentration for the preceding 2 to 3 months and is the standard test for identifying prolonged periods of hyperglycemia.To compare pancreas utilization rates before and after implementation of hemoglobin A1c testing.A retrospective study of data from the New York Organ Donor Network was conducted. Potential donors were defined as standard criteria donors who had no history of diabetes and were not seropositive for hepatitis B or C. Criteria for "ideal" potential pancreas donors were based on age, body mass index, lipase level, and terminal creatinine level. Potential donors who did not meet the criteria for ideal donors were considered "expanded" potential pancreas donors. Pancreas utilization rate was defined as the number of pancreata transplanted divided by the number of potential pancreas donors.Of 779 standard criteria donors, 691 (89%) were potential pancreas donors: 251 ideal (36%) and 440 expanded (64%) donors. In 2005 and 2006, before hemoglobin A1c testing, pancreas utilization rates were 21% and 18%, respectively. In 2008, 2009, and 2010, after hemoglobin A1c testing was incorporated, utilization rates were 27%, 28%, and 32%, respectively. Utilization of ideal donors increased from 33% to 51% (P= .003), and utilization of expanded donors increased from 11% to 17% (P= .05). Pancreas utilization increased 51.0%, and pancreas discards decreased 50.8% with the implementation of hemoglobin A1c testing.Hemoglobin A1c testing may increase utilization of ideal and expanded criteria pancreata.

Hepatic inflow clamping during hepatectomy introduces ischemia-reperfusion (I/R) injury, and many authors regard the addition of caval occlusion as adding increased risk. Ischemic preconditioning (IPC) is one of the protective strategies employed to reduce I/R injury in animal experiments and limited clinical series. The aim of the present study was to determine the impact of systematic adoption of IPC in patients undergoing complex hepatectomy under total hepatic vascular exclusion (TVE) based on outcomes review.The records of 93 patients who underwent major hepatectomy involving TVE at our center from February 1998 to December 2008 were reviewed. These patients were divided into two groups: group 1 (n = 55, TVE alone) and group 2 (n = 38, TVE with IPC). IPC was performed by portal triad clamping for 10 min followed by 3-5 min of reperfusion prior to TVE and resection.The two groups were comparable regarding demographics, underlying liver diseases, indications for hepatectomy, duration of TVE, and preoperative liver and kidney function tests. Overall postoperative laboratory results of liver function tests were not significantly different between the two groups. Creatinine levels and prothrombin times were not significantly different between the groups. The use of IPC had no impact on the duration of the operation, blood loss, or hospital stay. The morbidity rates were 37.5 and 34.2 %, respectively.Our adoption of IPC as a protective strategy against I/R injury under TVE did not affect operative or laboratory parameters and clinical outcomes when compared to continuous clamping for comparable ischemic periods.

Whereas verbal interactional behaviors have been repeatedly found to distinguish the families of persons with and without major psychiatric disorders, there has been comparatively little examination of the discriminative value of nonverbal interactional behaviors. We developed the Nonverbal Interactional Coding System to measure "affiliative" and "distancing" nonverbal behaviors in 18 schizophrenic and 18 bipolar patients and their parents during 10-minute interactions conducted during a posthospital period. Bipolar patients and their parents displayed affiliative nonverbal behaviors ("illustrator gestures" or "prosocial behaviors") for longer durations than schizophrenic patients and their parents. In contrast, parents of schizophrenic patients displayed distancing nonverbal behaviors (looking away) for longer durations than those of bipolar patients. The nonverbal interactional data added to the statistical strength of patients' and parents' verbal interactional data in distinguishing between these diagnostic groups. Nonverbal interactional behaviors are important variables to consider in interventions aimed at improving the communication skills of families coping with psychiatric disorders.

Relatives' (N = 77) perceptions of their recent interactional behavior with a schizophrenic family member (N = 51), as measured by an adjective checklist, were compared with outside observer ratings of the relatives' Affective Style (AS) and the patients' Coping Style (CS) during a family interaction task. Results indicated that, overall, the relatives in the present sample perceived their own interactional behavior toward the patient, as well as the patients' behavior toward them, in a way that paralleled their affective behavior as assessed by outside raters. Moreover, the relatives' rated their relationship with the patient in a fashion that was more predictive of the observed interactional behavior of both the relatives and the patients than were the outside observers' ratings of the relatives' Expressed Emotion (EE) measured either at the patients' index hospitalization (using the Camberwell Family Interview, CFI-EE) or during the post-discharge period (assessed with a brief Five-Minute Speech Sample method, FMSS-EE).

The course of bipolar disorder is less positive than previously believed. Combining family and pharmacological treatment programs may be valuable in enhancing clinical and social outcome.

This article is an overview of our studies of childhood-onset schizophrenia. Data are presented demonstrating that (1) the majority of the sample showed continuing schizophrenia as they progressed through adolescence; (2) there was considerable variability in outcome, defined by global adjustment scores, with 56 percent of the sample showing improvement in functioning during a 2- to 7-year followup period and the other 44 percent showing minimal improvement or a deteriorating course; (3) schizophrenia in childhood could be diagnosed by the same criteria used for adults and was associated with severe dysfunction; and (4) some intrafamilial attributes found to be associated with schizophrenia in adults were also associated with schizophrenia in children, but there were some differences in the family environmental correlates of childhood- and later-onset schizophrenia. These data are consistent with the hypothesis that childhood- and later-onset schizophrenia represent the same illness or illnesses. Additional research is needed, however, to clarify the etiologic and clinical significance of the atypical early onset in childhood cases.

Many scholars are skeptical of family member reports on their interpersonal relationships. Familial reports are assumed to be biased by social desirability as well as other factors. In this study, a latent variables modeling approach was employed to evaluate rater reliability and bias in mother, father, and child ratings of parent-child negativity. Results based on 78 clinical families demonstrate that family member ratings contain a significant "true score" component that correlates with observer ratings of parental behavior. The presence of systematic rater effects is also demonstrated. The latent variables approach, which provides statistical control for rater effects, is recommended for the analysis of this type of data.

The association between expressed emotion (EE) and psychiatric disorders was investigated in a community survey of 108 preadolescent children. Results indicated that the two components of EE, critical comments and emotional overinvolvement, identified non-overlapping subsets of families and displayed diagnostic specificity. Significantly higher rates of disruptive behavior diagnoses were observed in children of parents who expressed high levels of criticism, while children of parents who expressed high levels of emotional overinvolvement were significantly more likely to have an anxiety disorder when compared to the remaining sample. Findings support the utility of this brief measure of EE in epidemiologic samples.

Background. Despite marked improvement in short-term renal allograft survival rates (GSR) in recent years, improvement in long-term GSR remained elusive. Methods. We analysed the kidney transplant experience at our centre accrued over four decades to evaluate how short-term and long-term GSR had changed and to identify risk factors affecting graft survival. The study included 1476 adult recipients of a deceased-donor kidney transplant who were transplanted between 1963 and 2006 and who had received one of five distinct immunosuppressive protocols. Results. Five-year actual GSR steadily improved over the years as immunosuppressive therapy evolved (22–86%, P < 0.001) in spite of an increasing trend in the transplantation of higher-risk donor–recipient pairings. For those whose grafts functioned for the first year, subsequent 4-year GSR (5-year conditional GSR) also improved significantly (63–92%, P < 0.001). Acute rejection and delayed graft function (DGF) were the most significant risk factors for actual graft survival, while acute rejection was the only significant risk factor for conditional GSR. Use of kidneys from expanded-criteria donors (ECD) was not a risk factor, compared to the use of standard-criteria donor kidneys for either 5-year actual or conditional GSR. There was an impressive decline in the incidence of acute rejection events (77.4–5.8%, P < 0.001). While the DGF rate had decreased, it still remained high (68.7–38.5%, P < 0.001). Conclusions. We found a significant improvement in both short-term and long-term GSR of deceased-donor kidney transplants over the last four decades. These improvements are most likely related to the decreased incidence of acute rejection episodes. Minimizing acute rejection events and preventing DGF could result in further improvement in the GSR. Our experience in the judicious use of ECD kidneys suggests that this source of kidneys could be expanded further.

The Developmental Processes in Schizophrenic Disorders project is a longitudinal study of schizophrenic patients who have recently had a first episode of psychosis. The project focuses on discriminating characteristics of schizophrenic patients that are "stable vulnerability indicators," "mediating vulnerability factors," and "episode indicators" by comparing normal subjects to schizophrenic patients assessed in clinically remitted and psychotic states. A parallel project goal is to identify predictors of relapse, social and work impairment, and illness course among potential psychobiological vulnerability factors and environmental potentiating factors. Hypothesized vulnerability factors and potential environmental stressors are examined first under standardized maintenance antipsychotic medication conditions for at least 1 year. Patients showing stable remission of psychosis after 1 year of maintenance antipsychotic medication are invited to enter drug crossover and withdrawal protocols to determine the need for continuous antipsychotic medication. Vulnerability and stress factors are again assessed. A summary of results to date is presented. Deficits in early components of processing visual arrays and in sustained discrimination of successive ambiguous perceptual inputs are relatively stable across psychotic and clinically remitted states in the schizophrenic patients. Performance on a vigilance task demanding active, working memory also remains abnormal during clinical remission but covaries significantly with psychotic state and is a candidate for a mediating vulnerability factor. Autonomic activation level does not appear to be an enduring vulnerability factor, but it predicts the extent of short-term symptomatic recovery and may mediate the impact of stressors. Under conditions of standardized, injectable antipsychotic medication, independent stressful life events and highly critical attitudes toward the patient in the social environment predict relapse risk. Prospective data suggest that signs and symptoms prodromal to psychotic relapse may be present in about 60 percent of patients.

Both high expressed emotion (EE) and psychiatric disorders were frequent in the parents of children and adolescents with disruptive behavior disorder (DBD, N = 34) and obsessive compulsive disorder (OCD, N = 49) compared to normal controls (NC, N = 41). Parental psychiatric diagnosis was significantly related to high-EE in fathers (p = .0002) and mothers (p = .0001) of all groups combined, and in parents of the ill groups (p = .03). Absence of diagnosis was associated with low-EE in fathers (p = .0006) and mothers (p = .04) of the controls. Psychiatric diagnosis was the only significant predictor for high-EE in fathers, while for mothers child's diagnosis was a stronger predictor.

Changes in relatives' affective attitudes are important contributors to the impact of family psychoeducational programmes on the course of schizophrenia. It remains unclear whether similar changes occur in the interactional style of schizophrenic patients participating in psychoeducational treatment. This study examined changes in the interactional style (coping style) of 33 schizophrenic patients in individual or family treatment. Significant changes were seen in the interactional style of the patients participating in the individual treatment. Similar changes were evident, but not significant, in the family treatment group. The quality of patient interactional style before or after treatment did not predict relapse in either group. Changes in relatives' interactional style early in family treatment are necessary to affect the short-term course of schizophrenia. Modification in patient behaviour during the early phase does not have similar predictive value.

Communication deviance (CD) refers to confusing and fragmented communication that prevents family members from attaining a shared focus of attention and meaning. Levels of communication deviance based on individual parental projective test protocols — Thematic Apperception Test (TAT) and Rorschach — have repeatedly been found to be higher in parents of schizophrenic offspring than in parents of normal or nonpsychotic offspring. CD has also been measured in family transactions in which parents and their offspring interact with one another around a projective test stimulus, the Consensus Rorschach. There have been relatively few attempts to measure specific CD codes in familial interaction that is not initiated around an ambiguous visual stimulus. The present article examines the reliability and construct validity of an interactional measure (ICD) obtained from family transactions in which parents and patients are working toward the solution of a salient family problem. ICD from this family problem-solving task was compared to more traditional measures of CD from parental TAT protocols in a sample of 59 parents of 37 recent-onset schizophrenic patients. Results indicated that CD could be reliably measured in an interactive setting not initiated around a projective test stimulus, and provided evidence for the construct validity of ICD.

This study tested whether parent and child affective attitudes and interactional behavior co-varied with the presence or absence of associated aggressive symptomatology in families with an attention deficit hyperactivity disorder (ADHD) child. Affective attitudes of both parents and their ADHD sons were studied using a modified measure of expressed emotion, the five minute speech sample (FMSS-EE), in 29 families. A direct interaction task was also used to measure verbal and non-verbal communication. FMSS-EE status predicted parental interactional behavior, but the degree of child aggressiveness did not. The child's behavior towards parents, however, was highly correlated with their aggressiveness but not their EE status regarding their parents, despite the fact that child and parent EE were highly correlated. The study supports the notion that aggressiveness and a negative family climate may be independent factors in determining the long-term course of ADHD children.

Objective. We analyze and discuss the importance of intrarenal color duplex ultrasonography (CDUS) in the diagnosis and differential diagnosis of vascular complications in renal transplants. Methods. We retrospectively reviewed results of CDUS, especially intrarenal CDUS, in 102 consecutive inpatients with vascular complications of renal transplants from January 1, 2000, to December 31, 2006. Correlations between CDUS and magnetic resonance angiography, digital subtraction angiography, surgical findings, and clinical diagnoses were studied. Results. Abnormal findings on intrarenal CDUS clearly represent vascular complications primarily located at the main renal vessels and intrarenal vessels. In our study, there were 5 cases of false-negative intrarenal arteriovenous fistulas, 1 case of false-positive transplant renal vein thrombosis, and 2 cases of false-negative transplant renal artery stenosis. The accuracy of detecting vascular complications of renal transplants with CDUS was 92% (94/102). Conclusions. Intrarenal CDUS is a noninvasive, accurate diagnostic tool that can be administrated portably and is easily repeatable, thereby making it not only a highly valuable imaging technique but also the method of choice in screening and diagnosing vascular complications of renal transplants.

The objective of this study was to evaluate the effect of systematic utilization of extended donor criteria liver allografts (EDC), including living donor allografts (LDLT), on patient access to liver transplantation (LTX).Utilization of liver allografts that do not meet traditional donor criteria (EDC) offer immediate expansion of the donor pool. EDC are typically allocated by transplant center rather than regional wait-list priority (RA). This single-institution series compares outcomes of EDC and RA allocation to determine the impact of EDC utilization on donor use and patient access to LTX.The authors conducted a retrospective analysis of 99 EDC recipients (49 deceased donor, 50 LDLT) and 116 RA recipients from April 2001 through April 2004. Deceased-donor EDC included: age65 years, donation after cardiac death, positive viral serology (hepatitis C, hepatitis B core antibody, human T-cell lymphotrophic), split-liver, hypernatremia, prior carcinoma, steatosis, and behavioral high-risk donors. Outcome variables included patient and graft survival, hospitalization, initial graft function, and complication categorized as: biliary, vascular, wound, and other.EDC recipients were more frequently diagnosed with hepatitis C virus or hepatocellular carcinoma and had a lower model for end-stage liver disease (MELD) score at LTX (P0.01). Wait-time, technical complications, and hospitalization were comparable. Log-rank analysis of Kaplan-Meier survival estimates demonstrated no difference in patient or graft survival; however, deaths among deceased-donor EDC recipients were frequently the result of patient comorbidities, whereas LDLT and RA deaths resulted from graft failure (P0.01). EDC increased patient access to LTX by 77% and reduced pre-LTX mortality by over 50% compared with regional data (P0.01).Systematic EDC utilization maximizes donor use, increases access to LTX, and significantly reduces wait-list mortality by providing satisfactory outcomes to select recipients.

Limited middle segment pancreatectomy, or central pancreatectomy, has been described for sparing normal pancreatic tissue during resection of benign neoplasms of the pancreatic neck. Anatomic reconstruction after central pancreatectomy has been reported in other series with creation of a Roux-en-Y loop of jejunum for a mucosa-to-mucosa pancreaticojejunostomy.Hospital charts and outpatient records were reviewed for 12 consecutive patients undergoing central pancreatectomy from August 1999 to November 2002.We performed central pancreatectomy with pancreaticogastrostomy in 12 patients: 5 with serous cystadenomas, 6 with mucinous cystadenomas, and 1 with neuroendocrine tumor. All tumors were located in the body or neck of the pancreas, measuring a mean +/- standard deviation (SD) of 2.5 +/- 1.2 cm. Median postoperative hospital stay was 6.5 days (range 5 to 15 days). There were no intraoperative complications. Perioperative complications included two urinary tract infections and one readmission for acute pancreatitis. There were no pancreatic leaks or fistulas in this series. Two of the 12 patients experienced endocrine insufficiency with elevated glycosylated hemoglobin levels during outpatient followup. None of the 12 patients experienced exocrine insufficiency.Central pancreatectomy with pancreaticogastrostomy reconstruction is safe and technically advantageous over Roux-en-Y pancreaticojejunostomy, and should be considered a safe reconstruction technique after central pancreatectomy for benign disease.

We describe two cases involving male foreign nationals (a Chinese and a Georgian) treated in a U.S. hospital. Both patients had terminal illnesses, and both cases involved clashes between families and the treating physicians, which occurred because of differing cultural beliefs about truth disclosure. Based on the specific backgrounds of these two patients, we discuss ethical and cultural considerations and make suggestions for physicians who care for ethnically diverse patients.

This study assessed whether therapist adherence to the family focused treatment model for patients with bipolar disorder and their relatives was associated with patient outcomes at one year after treatment entry. A total of 78 videotaped sessions of FFT consisting of 26 families with a member with bipolar disorder (3 sessions/family) were rated on fidelity using the Therapist Competence/Adherence Scale (TCAS; see Endnote 1, p. 130). Patients' outcomes (relapse status) were assessed using the Brief Psychiatric Rating Scale (BPRS) and selected items from the Schedule of Affective Disorders and the Schizophrenia-Change (SADS-C) scale (measured at 3-month intervals for 12 months). Contrary to expectations, therapist fidelity was not related to overall outcome as assessed by the BPRS and the SADS-C. Among patients who did relapse, higher levels of cooperation among therapists predicted a later date for relapse than did lower levels of cooperation. Surprisingly, and in opposition to the study's hypotheses, patients who were hospitalized because of relapses had therapists who were rated as more competent in their ability to conduct the problem-solving module of FFT. Study implications are discussed.

Thought disorder and communication patterns during an interactional task were examined in families of children with schizophrenia-spectrum disorders (schizophrenia and schizotypal personality disorder), depressed children, and normal controls. Children with schizophrenia-spectrum disorders showed significantly more thought disorder than their normal peers; levels of thought disorder among depressed children fell between those observed in the other two groups but did not differ significantly from either of them. Similarly, mothers of children with schizophrenia-spectrum disorders showed more thought disorder than mothers of normal control children but did not differ from mothers of depressed children. Children with schizotypal personality disorder did not differ from children with schizophrenia. These findings demonstrate that the thought disorder present in childhood-onset schizophrenia and schizotypal personality disorders is manifest in an important social context, the family.

Expressed emotion (EE) was examined, using the brief Five Minute Speech Sample measure, in families of (1) children with depressive disorders, (2) children with schizophrenia spectrum disorders, and (3) normal controls screened for the absence of psychiatric disorder. Consistent with the hypothesis of some specificity in the association between EE and the form of child disorder, rates of EE were significantly higher among families of depressed children compared to families of normal controls and families of children with schizophrenia spectrum disorders. Within the depressed group, the presence of a comorbid disruptive behavior disorder was associated with high levels of critical EE, underscoring the need to attend to comorbid patterns and subtypes of EE in future research.

Relatives' ratings of their affective attitudes toward a schizophrenic family member (N = 54) on a self-report adjective checklist were compared with two methods for rating expressed emotion (EE)--the original Camberwell Family Interview (CFI-EE) and a Five-Minute Speech Sample method (FMSS-EE). Eighty-four relatives were included in the sample. Results indicate that, in general, the relatives in the present sample perceive in themselves attitudes toward the patient that parallel those assessed by outside raters. A higher rate of correspondence was found between adjective ratings and concurrent FMSS-EE status than with prior CFI-EE status. Relatives classified as high-EE, critical by either method, were more readily discriminable in their adjective ratings from those rated low-EE than were relatives rated high-EE on the basis of emotional overinvolvement.

Both researchers and therapists who study schizophrenia make inferences about enduring family roles from observed patterns of interactional talking behavior within families. Evidence regarding the stability of these patterns is rarely investigated. The present study examined the short-term stability of intrafamilial speech patterns (who talks to whom) across two consecutive discussions. The sample was composed of families containing a recent-onset, adult schizophrenic patient. All discussions involved two biological parents and a young adult patient (N = 28). Families were classified into one of three interactional role-structure categories based on the intrafamilial speech patterns in two 10-minute discussions obtained in the same session. In addition, the affective style (Doane, West, Goldstein, et al., 1981) of the content of the discussions was coded. The results indicated that intrafamilial speech patterns were relatively stable across two discussions despite variations in the focus of the problem discussed. Further, when one parent was predominant in the discussion, a higher rate of negative affective statements was observed than when both parents were equal participants. The results provide further support for the use of discussion tasks in generating meaningful family interaction data.

Prospectively collected data on 19 recently hospitalized patients with bipolar disorder were examined for prodromal changes preceding relapse. The 4-month periods before six manic and six depressive relapses were compared with each other and with a comparable period for seven patients who did not relapse. The Brief Psychiatric Rating Scale was used to assess symptoms. Significant elevations in unusual thought content were found 1 month before manic relapse. Depressive relapsers evidenced higher levels of conceptual disorganization throughout the prerelapse period. Nonrelapsers showed very stable symptom profiles.

The Five-Minute Speech Sample (FMSS; Magana et al., 1986) is a brief method designed to assess the “expressed emotion” (EE) status of a respondent. The FMSS-EE rating is derived from statements made by a patient's key relative during a 5-minute monologue, with codes similar to those used in the original EE rating system (e.g., criticism and emotional overinvolvement). Rating is done from the audiotape and takes about 15–30 minutes. The article reports on the results of a cross-national study carried out in Germany using the FMSS with a sample of 60 relatives of schizophrenic patients. Results indicated that (1) German investigators could readily learn the system and could achieve a high degree of interrater reliability; (2) the association with the original index of EE, the Camberwell Family Interview, was comparable to that found by Magana et al.; and (3) the method yields very stable data over a 4–5 week retest period.

Background This study examined whether the combination of patients' neurocognitive deficits and criticism by others would predict the emergence of patients' unusual thinking during stressful family transactions. Methods When clinically stable, 41 patients with recent-onset schizophrenia completed 2 versions of a visual vigilance task, the Continuous Performance Test (CPT). One CPT emphasized early perceptual processing, while the other stressed immediate, working memory. On a separate occasion, patients and family members participated in a 20-minute interaction in which the number of relatives' criticisms and patients' unusual thoughts was assessed. Results In a hierarchical regression model, after entering performance on the CPT demanding immediate, working memory, and the number of criticisms by family members, the interaction of CPT performance and criticism significantly predicted the number of patients' unusual thoughts during the family session ( r 2 change = 0.09; P = .03). Post hoc analyses revealed that the number of criticisms and odd thoughts correlated significantly ( r = 0.59, P = .03) for patients who had poor memory-load CPT performance, but were unrelated ( r = −0.07) for patients who did well on the memory-load CPT. The CPT emphasizing early visual processing, either alone or in combination with interpersonal criticism, did not predict the number of patients' unusual thoughts during the interaction. Conclusion The results suggest that the combination of patients' working memory deficits and interpersonal criticism jointly predicts psychotic thinking, consistent with a model of schizophrenia that emphasizes the interaction of neurocognitive vulnerability and psychosocial stress factors.

Tests of attention/information processing, the continuous performance test (CPT) and the span of apprehension task (SAT), were given to 25 schizophrenic patients and their mothers. Measures of communication deviance also were obtained from the mothers. Comparison of these assessments in the mothers revealed different transactional profiles for good attenders and poor attenders on the CPT and on the SAT. The relationships between generations (patient and mother) differ from the within-individual relationships. CPT performance by the patient is not significantly correlated with scores from the mother. However, SAT performance by the patient could be related to SAT performance by the mother and specific communication deviance factor scores.
