Proteomic studies of VEGFR2 in human placentas reveal protein associations with preeclampsia, diabetes, gravidity, and labor.

VEGFR2 (Vascular endothelial growth factor receptor 2) is a central regulator of placental angiogenesis. The study of the VEGFR2 proteome of chorionic villi at term revealed its partners MDMX (Double minute 4 protein) and PICALM (Phosphatidylinositol-binding clathrin assembly protein). Subsequently, the oxytocin receptor (OT-R) and vasopressin V1aR receptor were detected in MDMX and PICALM immunoprecipitations. Immunogold electron microscopy showed VEGFR2 on endothelial cell (EC) nuclei, mitochondria, and Hofbauer cells (HC), tissue-resident macrophages of the placenta. MDMX, PICALM, and V1aR were located on EC plasma membranes, nuclei, and HC nuclei. Unexpectedly, PICALM and OT-R were detected on EC projections into the fetal lumen and OT-R on 20-150 nm clusters therein, prompting the hypothesis that placental exosomes transport OT-R to the fetus and across the blood-brain barrier. Insights on gestational complications were gained by univariable and multivariable regression analyses associating preeclampsia with lower MDMX protein levels in membrane extracts of chorionic villi, and lower MDMX, PICALM, OT-R, and V1aR with spontaneous vaginal deliveries compared to cesarean deliveries before the onset of labor. We found select associations between higher MDMX, PICALM, OT-R protein levels and either gravidity, diabetes, BMI, maternal age, or neonatal weight, and correlations only between PICALM-OT-R (p < 2.7 × 10-8), PICALM-V1aR (p < 0.006), and OT-R-V1aR (p < 0.001). These results offer for exploration new partnerships in metabolic networks, tissue-resident immunity, and labor, notably for HC that predominantly express MDMX.

Efficacy and Safety of Sofosbuvir/Velpatasvir Plus Ribavirin in Patients with Hepatitis C Virus-Related Decompensated Cirrhosis.

A fixed-dose combination of sofosbuvir/velpatasvir (SOF/VEL) plus weight-based ribavirin (RBV) for 12 weeks is recommended for the treatment of patients with hepatitis C virus (HCV)-associated decompensated cirrhosis. However, large global studies, while confirming the effectiveness of SOF/VEL in a broad range of patients, often exclude these patients. This Phase 2, single-arm, open-label study in adult patients with HCV-associated decompensated cirrhosis in France and the USA aimed to provide further data on the safety and efficacy of SOF/VEL plus RBV for 12 weeks in this population. Patients were treated with a fixed-dose combination of SOF 400 mg/VEL 100 mg plus weight-based RBV once daily for 12 weeks. The inclusion criteria were chronic HCV infection (≥6 months), quantifiable HCV RNA at screening, Child-Turcotte-Pugh class B or C cirrhosis, and liver imaging within 6 months of Day 1 to exclude hepatocellular carcinoma. Among 32 patients who initiated treatment, 78.1% achieved sustained virologic response 12 weeks after the end of treatment (SVR12). Failure to achieve SVR12 was due to non-virologic reasons (investigator discretion, n = 1; death, n = 6). All 25 patients in the per-protocol population achieved SVR12 and all but one achieved sustained virologic response 24 weeks after the end of treatment. Adverse events (AEs) were as expected for a patient population with advanced liver disease. All Grade 3-4 and serious AEs and deaths were deemed unrelated to treatment. In patients with HCV-associated decompensated cirrhosis, SOF/VEL plus RBV achieved high SVR12 rates and was generally well tolerated.

Outcomes in Renal Cell Carcinoma With IVC Thrombectomy: A Multiteam Analysis Between an NCI-Designated Cancer Center and a Quaternary Care Teaching Hospital.

INTRODUCTION: Interteam performance and Clavien-Dindo (C-D) complications in renal cell carcinoma with inferior vena cava thrombectomy (RCC-IVCT) have not been reported. We aimed to describe complications by the degree of complexity and surgical teams in a collaborative effort between a National Cancer Institute-designated Comprehensive Cancer Center and a Quaternary Care Teaching Hospital. METHODS: Between January 2011 and May 2019, 73 consecutive RCC-IVCT were included. C-D grades III or higher were captured. Teams involved were urologic-oncology, vascular, hepatobiliary/transplant, and cardiothoracic. The Mayo Clinic tumor thrombus classification was used. RESULTS: Overall complication rate was 42% (n = 31). Nineteen percent had grade III, 18% had grade IV, and 6% had grade V complications. Patients with level IV thrombus had the highest in-hospital mortality rate (75%). Thrombus level did not show a correlation to complication rates (14% level I, 45% level II, 32% level III, 42% level IV). A positive correlation found between the number of teams involved and complication rates (35% with 2-team, 59% with 3-team, P = .059). Thromboembolic events (6% vs 24%, P = .02) and disposition other than home (22% vs 48%, P = .01) were statistically lower for the 2-team groups. Two-team in-hospital mortality was 1/51 (2%) versus 3-team (3/22,14%, (P = .07). No statistical differences were found in infections, thromboembolic events, and grades of complications between surgical teams. CONCLUSIONS: Despite similar interteam performance, the consistency of surgeons in high complexity cases could improve outcomes further. Complexity was higher for hepatobiliary/transplant and cardiothoracic teams. A combination of intraoperative events and patient selection (comorbidities and age) contributed to death. Overall, in-hospital mortality was lower than in most reported series.

Effects of Subsequent Systemic Anticancer Medication Following First-Line Lenvatinib: A Post Hoc Responder Analysis from the Phase 3 REFLECT Study in Unresectable Hepatocellular Carcinoma.

INTRODUCTION: Understanding the relationship between subsequent-line therapies and overall survival (OS) is important for maximizing OS for patients with hepatocellular carcinoma. OBJECTIVE: In this post hoc analysis, we investigated OS in lenvatinib- and sorafenib-treated patients from the REFLECT study, who then received subsequent anticancer medication during the survival follow-up period. METHODS: The follow-up period commenced at the first off-treatment visit after stopping the study medication and continued until study termination, withdrawal of consent, or death. OS and objective response rate were calculated for patients who did or did not receive poststudy anticancer medication for both treatment arms, as well as for the overall cohort. We investigated the subset of patients who responded to first-line treatment and subsequently received anticancer medication. RESULTS: The OS for patients initially randomized to first-line lenvatinib (versus first-line sorafenib) and who then received any subsequent anticancer medication was 20.8 vs. 17.0 months (hazard ratio [HR] 0.87; 95% CI 0.67-1.14). The OS for patients who initially received first-line lenvatinib (versus first-line sorafenib) and who did not receive any subsequent anticancer medication was 11.5 vs. 9.1 months (HR 0.90; 95% CI 0.75-1.09). Responders to first-line lenvatinib who received subsequent medication had a median OS of 25.7 months (95% CI 18.5-34.6); responders to first line-sorafenib who received subsequent medication had a median OS of 22.3 months (95% CI 14.6-not evaluable). CONCLUSIONS: In this post hoc analysis of all patients in the REFLECT study who received subsequent anticancer medication, OS was increased compared with patients who did not receive any subsequent anticancer medication. In a subset analysis of responders who had received subsequent anticancer medication, use of first-line lenvatinib led to a slightly longer median OS; more research is needed on the benefits of using first-line lenvatinib compared with sorafenib.

Teachers' involvement and students' self-efficacy: Keys to achievement in higher education.

We study the relative importance of the three dimensions of need-supportive teaching (NST) and students' self-efficacy to gain new knowledge about students' achievement in higher education. NST assumes that teachers are key to the motivation of students, providing autonomy support, structure (support of competence), and involvement (support of relatedness). In turn, self-efficacy raises students' confidence in their ability to succeed in academic tasks. Drawing on 86,000 records of teaching evaluations by students at the University of Girona (Spain), we present evidence that teachers' involvement and students' self-efficacy are the two elements most strongly and positively related to achievement. Students obtain higher marks when they believe that their teachers are dependable and available to offer resources, and when they feel capable of organizing and implementing the courses of action necessary to acquire knowledge. We also find that students' experience of autonomy support and structure are negatively (or not) correlated with achievement. Subgroup analyses also indicate that students have different needs in different knowledge areas.

Malleable Transplant Criteria: At What Cost?

An 18-year-old male who had been diagnosed at age 7 with a rare, progressive liver disease was referred to the transplant center and received a transplant, even though he did not meet the center's criteria for a patient with hepatopulmonary syndrome (HPS). Complications required relisting the patient urgently, but he eventually fully recovered; total hospital charges for his treatment exceeded $5 million. Reflection upon the case resulted in analysis of two ethical questions: primarily, clinician obligation to balance the provision of actuarially fair health care to society against the healing of a single patient; secondarily, the effects of malleable transplant criteria on trust in the patient selection process. We affirmed that physicians should not be principally responsible for justifying financial investment to society or for upholding beneficence beyond the individual physician and patient relationship in order to contain costs. We concluded, however, that such instances, when combined with manipulation of transplant center criteria, pose a potential threat to public trust. We therefore suggested that transplant centers maintain independent ethics committees to review such cases.

Pharmacokinetics of Once-Daily Extended-Release Tacrolimus Tablets Versus Twice-Daily Capsules in De Novo Liver Transplant.

The pharmacokinetics of once-daily extended-release tacrolimus tablets (LCPT) in de novo liver transplantation have not been previously reported. In this phase II, randomized, open-label study, de novo liver transplant recipients were randomized to LCPT 0.07-0.13 mg/kg/day (taken once daily; n = 29) or twice-daily immediate-release tacrolimus capsules (IR-Tac) at 0.10-0.15 mg/kg/day (divided twice daily; n = 29). Subsequent doses of both drugs were adjusted to maintain tacrolimus trough concentrations of 5 to 20 ng/mL through day 90, and 5-15 ng/mL thereafter. Twenty-four-hour pharmacokinetic profiles were obtained on days 1, 7, and 14, with trough concentration and efficacy/safety monitoring through year 1. Similar proportions of patients in both groups achieved therapeutic trough concentrations on days 7 and 14 (day 7: LCPT = 78%, IR-Tac = 75%; day 14: LCPT = 86%, IR-Tac = 91%) as well as similar systemic and peak exposure. There was a robust correlation between drug concentration at time 0 and area under the concentration-time curve for both LCPT and IR-Tac (respectively, day 7: r = 0.86 and 0.79; day 14: r = 0.93 and 0.86; P < .0001 for all). Dose adjustments during days 1 to 14 were frequent. Thirty-five patients completed the extended-use period. No significant differences in adverse events were seen between groups. Incidence of biopsy-proven acute rejection (LCPT = 6 and IR-Tac = 4) was similar on day 360. Between formulations, overall exposure was similar at 1 week after transplant with the characteristic delayed-release pharmacokinetic profile of LCPT demonstrated in this novel population. These data support further investigation of the safety and efficacy of LCPT in de novo liver transplantation.

Is Fulminant Hepatic Failure the Nemesis for Liver Transplant Centers? A Two Decade Psychosocial and Long-Term Outcome Study.

Long-term outcomes in liver transplantation for acute liver failure (ALF) are poorly studied. The aim of the study was to identify psychosocial variables that affect adherence and late survival. Retrospective review of ALF liver transplant (LTx) patients between 1997 and 2017 (n = 47) was conducted. Psychosocial history, life stressors, and ability to participate in transplant were recorded. Survival was calculated using Kaplan-Meier and logistic regression. Eleven patients (31.5%) had poor adherence, four died, all from graft failure. Of 13 with fair and 12 with good adherence, two died, no adherence related. Poor adherence was associated with higher mortality (P = 0.04), but by Kaplan-Meier, their five- and 10-year survival was 78 and 54 per cent, versus fair and good adherence (five years, 83% P = 0.3). Participating in transplant decision improved survival (five years, 80%) versus not participating (five years, 61%; P = 0.03). Of 10 early deaths, three were neurologic and five of sepsis. Overall, one- and five-year survival was 78 and 69 per cent. ALF represents the nemesis of LTx programs. Psychosocial aspects pre-LTx, stressors, and poor adherence affected survival in this series. No improvement over two decades of ALF LTxs was observed. The ethics of transplanting these high-risk patients will be the subject of our future research.

Outcomes of abdominal surgeries in cirrhotic patients performed by liver transplant surgeons: Are these safe?

BACKGROUND: Elective abdominal surgeries in patients with cirrhosis have been discouraged due to the high risk of complications. This study investigates the outcomes and safety of surgeries for hernias, and laparoscopic cholecystectomies in cirrhotic patients. METHODS: A retrospective cohort study that compared 91 cirrhotic patients to a control group of non-cirrhotic patients operated by liver transplant surgeons was conducted between 2009 and 2015. RESULTS: No statistical significance found in re-admission rates or complication rates (p = 0.21). Hernia recurrent rates were similar (p = 0.27). Survival rates among cirrhotic versus non cirrhotic group was 93.4% and 98.9% respectively (p = 0.0539). Amongst the 91 cirrhotic patients, there was a 100% survival rate for both ventral herniorrhaphies and laparoscopic cholecystectomy. Survival in umbilical and inguinal herniorrhaphies was 88.2% and 89.5% respectively. Mortality rate for umbilical and inguinal hernias was 11.7% and10.5% respectively. Mortality by Child-Pugh (CP) class were; 8.8% for CP B and 10.7% for CP class C. All CP class A patients survived. CONCLUSIONS: Our study indicates that elective operations could be performed safely with acceptable mortality in cirrhotic patients.

Successful Liver Transplantation for Hyperammonemic Fibrolamellar Hepatocellular Carcinoma.

Fibrolamellar hepatocellular carcinoma is a rare hepatocellular tumor usually arising in noninfected and noncirrhotic livers. Only 2 cases accompanied by hyperammonemia due to intrahepatic shunting have been reported. A 23-year-old white woman presented with a 2-week history of nausea, vomiting, generalized weakness, and intermittent right upper quadrant pain. Abdominal computerized tomography revealed a 13 x 9-cm hepatic mass. Core-needle biopsy revealed fibrolamellar hepatocellular carcinoma. She presented with coma due to hyperammonemia levels (peak at 437 mcg/dL) but without metastatic disease. She was urgently transplanted, started on daily sorafenib 8 weeks after transplantation, and was free of disease at 1 year after transplantation.

Building the multidisciplinary team for management of patients with hepatocellular carcinoma.

Optimal care of the patient with hepatocellular carcinoma (HCC) necessitates the involvement of multiple providers. Because the patient with HCC often carries 2 conditions with competing mortality risks (cancer and underlying cirrhosis), no single provider is equipped to deal with all of these patients' needs adequately. Multidisciplinary teams (MDTs) have evolved to facilitate care coordination, reassessments of clinical course, and nimble changes in treatment plans required for this complex group of patients. Providers or sites that elect to manage patients with HCC thus are increasingly aware of the need to build their own MDT or communicate with an established one. The availability of new communication technologies, such as teleconferencing or teleconsultation, offers the possibility of MDT expansion into underserved or rural areas, as well as areas such as correctional facilities. Although the availability of resources for HCC patient care varies from site to site, construction of an MDT is possible in a wide spectrum of clinical practices, and this article suggests a blueprint for assembly of such collaboration. Research strategies are needed to explain how MDTs improve clinical outcomes so that MDTs themselves can be improved.

Can sorafenib increase survival for recurrent hepatocellular carcinoma after liver transplantation? A pilot study.

Recurrence of hepatocellular carcinoma (HCC) remains a main detriment to long-term survival in liver transplants (LTx) for HCC. The study aims to review the use of sorafenib in recurrent HCC LTx in the Model End Stage Liver Disease era. Two hundred forty-seven patients with HCC LTx from 2002 to 2013 were included. Survival was calculated by the Kaplan-Meier (KM) method and Cox multivariate model. Twenty-two patients recurred (11%). By KM, overall survival was 27 months (standard deviation [SD], 3.2 months; median, 28.4 months). Mean time to recurrence was 16.9 months (SD, 2.8 months; median, 12 months). Nine patients were treated with sorafenib after recurrence. Median survival for sorafenib-treated patients was 42 months compared with a median of 16.2 months without sorafenib (-2 log likelihood ratio, P = 0.0582). By Cox, only sorafenib (P = 0.0233; hazard ratio, 8.528) and pathologic stage had a significant impact on survival. The recurrence rates of HCC LTx remain acceptable considering understaging and expansion of beyond Stage A. This pilot study of sorafenib in recurrent HCC demonstrates improved survival over historic controls. Many other factors affecting improved survival are explained. However, treatment remains palliative. Quality-of-life years and cost analysis need to be performed in this population.

Liver transplantation for hepatocellular carcinoma in Puerto Ricans: underutilization of a curative therapy.

OBJECTIVE: Hepatocellular carcinoma (HCC), the most common type of liver cancer, is becoming a healthcare burden for Puerto Rico and, in particular, for those clinics that specialize in liver disease. It is our hypothesis that liver transplantation, the most effective curative option for unresectable tumors, is underutilized. We describe in detail the outcomes of liver transplants for HCC in Puerto Ricans referred to a major liver transplant center in the USA. METHODS: Thirty-two Puerto Rican HCC patients receiving transplants (from January 1, 1997, through July of 2012) at Tampa General Hospital are described. Recurrence rates were calculated, and the Kaplan-Meier estimator was used for survival analysis. RESULTS: The proportion of transplants performed for HCC in our Puerto Rican patients was only 12% (p = 0.05). Disease-free survival at 1, 3, and 5 years was 93.7%, 83%, and 78.8%, respectively. Patient survival at 1, 3, and 5 years was 96.7%, 75%, and 67%, respectively. Sixty-nine percent of the 32 patients were alive at the mean follow-up of 56 months. The recurrence rate from 2002 to the present is 14%. CONCLUSION: This study provides the most comprehensive report detailing the relative benefits of utilizing liver transplantation as a curative option for Puerto Ricans with hepatocellular carcinoma. It also incorporates the first comprehensive review of the available literature of liver cancer in Puerto Rico. Survival and recurrence rates were comparable to published results. In Puerto Rico, liver transplantation for HCC patients has been underutilized. In order to improve outcomes over the next 2 decades, it is imperative that the healthcare system in Puerto Rico handle the burden of this disease using liver transplantation, locoregional therapies, and newer treatments for hepatitis C and HCC.

Expresión inmunohistoquímica de PCNA, Ki-67 y ciclina D1 en ameloblastomas multiquísticos / Immunohistochemical expression of PCNA, Ki-67 and cyclin D1 in solid ameloblastomas

Introducción: el ameloblastoma es un tumor odontogénico benigno, localmente agresivo, que debe su origen a partir de estructuras epiteliales involucradas en la odontogénesis. El objetivo del presente trabajo es identificar, por medio de técnicas inmunohistoquímicas, aspectos de los mecanismos regulatorios de proliferación celular y la relación de los diferentes subtipos histológicos con el comportamiento biológico de estos tumores. Materiales y métodos: se seleccionaron 10 ameloblastomas multiquísticos en los cuales se realizó inmunotinción con los marcadores PCNA, Ki-67 y Ciclina D1. La interpretación de las tinciones se basó en la intensidad, localización y los subtipos celulares. La valoración utilizada para contabilizar el número de células fue baja (menos del 10 por ciento), media (hasta el 50 por ciento) y alta (más del 50 por ciento). Resultados: la tinción fue positiva en 6 casos para PCNA, en 3 para Ki-67 y en 5 para ciclina D1, en las células basales periféricas, en los patrones foliculares y plexiformes, en las del esbozo del retículo estrellado y fue negativa en los patrones quísticos y acantomatosos. Conclusión: en base a los hallazgos se puede asumir que las células basales y parabasales de los patrones foliculares y plexiformes presentan mayor actividad proliferativa que otros patrones y determinarían la evolución y tratamiento

Nonalcoholic fatty liver disease epidemic and its implications for liver transplantation.

Nonalcoholic steatohepatitis (NASH) is increasingly recognized as the most common chronic liver disease worldwide. The aim of this study is to investigate the transplantation trends of liver transplant (LT) recipients with NASH. Using the United Network for Organ Sharing database, we found a steady increase in LT rate especially in those more than 65 years old. We identified differences across ethnic groups and United Network for Organ Sharing regions. This study highlights the impact of the rising prevalence of NASH on the demand for LT and provides invaluable information to healthcare policymakers and the transplant community about the target groups and geographic location for focused and early intervention.

Obesity portends increased morbidity and earlier recurrence following liver transplantation for hepatocellular carcinoma.

BACKGROUND: Obesity has been associated with poor oncologic outcomes following pancreatoduodenectomy for pancreatic cancer. However, there is a paucity of evidence on the impact of obesity on postoperative complications, oncologic outcome and survival in patients with hepatocellular carcinoma (HCC) undergoing orthotopic liver transplantation (OLT). METHODS: From a database of over 1000 patients who underwent OLT during 1996-2008, 159 patients with a diagnosis of HCC were identified. Demographic data, body mass index (BMI), perioperative parameters, recurrence and survival were obtained. Complications were grouped according to Clavien-Dindo grading (Grades I-V). RESULTS: There were increased incidences of life-threatening complications in overweight (58%) and obese (70%) patients compared with the non-obese patient group (41%) (P < 0.05). Furthermore, the incidence of recurrence of HCC was doubled in the presence of overweight (15%) and obesity (15%) compared with non-obesity (7%) (P < 0.05). Time to recurrence also decreased significantly. Differences in mean ± standard deviation survival in the overweight (45 ± 3 months) and obese (41 ± 4 months) groups compared with the non-obese group (58 ± 6 months) did not reach statistical significance. CONCLUSIONS: These findings indicate that BMI is an important surrogate marker for obesity and portends an increased risk for complications and a poorer oncologic outcome following OLT for HCC.

Early use of renal-sparing agents in liver transplantation: a closer look.

Renal dysfunction is a critical issue for liver transplant candidates and recipients. Acute nephrotoxicity and chronic nephrotoxicity, however, are the compromises for the potent immunosuppression provided by calcineurin inhibitors (CNIs). To maintain the graft and patient survival afforded by CNIs while minimizing renal dysfunction in liver transplant patients, the reduction, delay, or elimination of CNIs in immunosuppression regimens is being implemented more frequently by clinicians. The void left by standard-dose CNIs is being filled by nonnephrotoxic immunosuppressants such as mycophenolates and mammalian target of rapamycin inhibitors. The results of studies of renal-sparing regimens in liver transplant recipients have been inconsistent, and this may be explained upon a closer examination of several study-related factors, including the study design and the duration of follow-up.

Update on the management of cirrhosis - focus on cost-effective preventative strategies.

Cirrhosis is a chronic liver disease stage that encompasses a variety of etiologies resulting in liver damage. This damage may induce secondary complications such as portal hypertension, esophageal variceal bleeding, spontaneous bacterial peritonitis, and hepatic encephalopathy. Screening for and management of these complications incurs substantial health care costs; thus, determining the most economical and beneficial treatment strategies is essential. This article reviews the economic impact of a variety of prophylactic and treatment regimens employed for cirrhosis-related complications. Prophylactic use of ß-adrenergic blockers for portal hypertension and variceal bleeding appears to be cost-effective, but the most economical regimen for treatment of initial bleeding is unclear given that cost comparisons of pharmacologic and surgical regimens are lacking. In contrast, prophylaxis for spontaneous bacterial peritonitis cannot be recommended. Standard therapy for spontaneous bacterial peritonitis includes antibiotics, and the overall economic impact of these medications depends largely on their direct cost. However, the potential development of bacterial antibiotic resistance and resulting clinical failure should also be considered. Nonabsorbable disaccharides are standard therapies for hepatic encephalopathy; however, given their questionable efficacy, the nonsystemic antibiotic rifaximin may be a more cost-effective, long-term treatment for hepatic encephalopathy, despite its increased direct cost, because of its demonstrated efficacy and prevention of hospitalization. Further studies evaluating the cost burden of cirrhosis and cirrhosis-related complications, including screening costs, the cost of treatment and maintenance therapy, conveyance to liver transplantation, liver transplantation success, and health-related quality of life after transplantation, are essential for evaluation of the economic burden of hepatic encephalopathy and all cirrhosis-related complications.
