The glutamatergic neurotransmitter system may play an important role in attention-deficit hyperactivity disorder (ADHD). This 5-week, open-label, single-blind, placebo-controlled study reports the safety, pharmacokinetics and responsiveness of the metabotropic glutamate receptor (mGluR) activator fasoracetam (NFC-1), in 30 adolescents, age 12–17 years with ADHD, harboring mutations in mGluR network genes. Mutation status was double-blinded. A single-dose pharmacokinetic profiling from 50–800 mg was followed by a single-blind placebo at week 1 and subsequent symptom-driven dose advancement up to 400 mg BID for 4 weeks. NFC-1 treatment resulted in significant improvement. Mean Clinical Global Impressions-Improvement (CGI-I) and Severity (CGI-S) scores were, respectively, 3.79 at baseline vs. 2.33 at week 5 (P < 0.001) and 4.83 at baseline vs. 3.86 at week 5 (P < 0.001). Parental Vanderbilt scores showed significant improvement for subjects with mGluR Tier 1 variants (P < 0.035). There were no differences in the incidence of adverse events between placebo week and weeks on active drug. The trial is registered at https://clinicaltrials.gov/ct2/show/study/NCT02286817.

Background Atypical hemolytic uremic syndrome is an exceedingly rare thrombotic microangiopathy caused by accelerated activation of the alternative complement pathway. Case presentation Here, we report two cases of patients presenting with suspected atypical hemolytic uremic syndrome precipitated by coronavirus disease 2019 infection. The first patient, a 25-year-old Hispanic male, had one prior episode of thrombotic microangiopathy presumed to be atypical hemolytic uremic syndrome precipitated by influenza A, and re-presented with thrombocytopenia, microangiopathic hemolytic anemia, nonoliguric renal failure, and normal ADAMTS13 activity, with confirmed coronavirus disease 2019 positivity. The second patient, a 31-year-old Caucasian female, had no personal history of thrombotic microangiopathy, though reported a family history of suspected atypical hemolytic uremic syndrome. She presented with similar laboratory derangements, oliguric renal failure requiring hemodialysis, and confirmed coronavirus disease 2019 positivity. Both patients were treated with eculizumab with complete resolution of their hematologic and renal complications. Conclusion To our knowledge, this represents the largest case series of atypical hemolytic uremic syndrome precipitated by coronavirus disease 2019 in adults.

BackgroundPatient reports of health related quality of life can provide important information about the long-term impact of prostate cancer. Because patient symptoms and function can differ by age of the survivor, the aim of our study was to examine patient-reported quality of life and prostate symptoms by age at diagnosis among a registry of Dutch prostate cancer survivors.MethodsA population of 617 individuals from the Patient Reported Outcomes Following Initial Treatment and Long-Term Evaluation of Survivorship (PROFILES) database was surveyed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30) and prostate symptom (EORTC QLQ-PR25) scales. Age at diagnosis was the main independent variable, with three age categories: 60 years and younger, 61–70 years, and 71 years and older. Dependent variables were the EORTC-QLQ-C30 and EORTC QLQ-PR25 scales, divided into positive and negative outcomes. Positive measures of health-related quality of life included global health, physical functioning, role functioning, emotional functioning, cognitive functioning, and social functioning. Negative outcomes included fatigue, nausea, pain, dyspnea, insomnia, appetite, constipation, and diarrhea. We also assessed sexual activity, and urinary, bowel and hormonal symptoms. Descriptive analyses included frequencies with chi-square tests and medians with Kruskal-Wallis tests. Multivariable adjusted analyses were conducted by median regression modeling.ResultsAmong the numerous scales showing some unadjusted association with age group, only two scales demonstrated significant differences between prostate cancer patients age 71+ compared to the youngest group (age < 61) after multivariable adjustment. On average, the oldest patients experienced an 8.3-point lower median physical functioning score (β = − 8.3; 95% CI = − 13.9, − 2.8; p = 0.003) and a 16.7-point lower median sexual activity score (β = − 16.7; 95% CI = − 24.7, − 8.6; p < 0.001) while controlling for BMI, marital status, time since diagnosis, comorbidities (heart condition), Gleason score, and treatment (prostatectomy).ConclusionsResults suggest that patient age at diagnosis should be considered among factors that contribute to health-related quality of life outcomes for prostate cancer survivors. Implications for Cancer Survivors: A possible reevaluation of screening recommendations may be appropriate to acknowledge age as a factor contributing to health-related quality of life outcomes for prostate cancer survivors.

Background Hemophilia A is an X‐linked inherited bleeding disorder caused by deficiency of coagulation factor VIII. Factor VIII is activated as part of the intrinsic coagulation cascade. It plays a crucial role as the cofactor in the intrinsic “tenase” complex activating factor X to assist in clot formation. Absence or mutation of this coagulation factor leads to excessive bleeding. Clinical manifestations of hemophilia relate to bleeding from impaired hemostasis, sequelae from bleeding, or complications of coagulation factor infusion. Diagnostic criteria for Hemophilia A include factor VIII activity level below 40% of normal, presence of a mutated F8 gene, and the absence of von Willebrand disease (F8 gene ‐ Genetics Home Reference ‐ NIH. https://ghr.nlm.nih.gov/gene/F8). Patients who have this intrinsic defect in the coagulation cascade have a characteristically prolonged PTT. It is theorized that the majority of factor VIII is synthesized mainly in the liver, by way of liver sinusoidal endothelial cells (Arruda VR. Haematologica. 2015;100(7):849–850). Extrahepatic production also occurs in the endothelial cells, kidneys, and lymphatic tissue. In 1969, Marchioro et al showed that transplantation of normal liver to hemophilia dog could normalize plasma factor VIII levels (Marchioro T L, Science. 1969;163(3863):188–190). These results were subsequently proven in humans. Liver transplantation from hemophilia A donors without factor VIII inhibitor is not commonly performed due to the perceived risk of developing hemophilia A in the recipient. There is currently limited literature aimed at elucidating this risk. We present a case of liver transplantation in a hemophilia A donor to a recipient with no history of hemophilia A with literature reviewis a case report, objective and method do not apply. Objective and method We did a case report and literature review of a liver transplant receipient fro ma hemohpila A donor. Results The receipient of the liver from hemophilia A donor did not develop hemophilia post transplant and had normal factor VIII levels. conclusion To our knowledge, this is only the second case in humans of hemophilia A patient as a donor in liver transplantation. As the indications for liver transplantation have expanded, there is a need to expand the donor list, and possibly not exclude this population as viable donor option.

Hemophilia B, also called Christmas disease, is an X-linked inherited bleeding disorder that predominantly affects males, and it is caused by deficiency of coagulation factor IX. Factor IX is a coagulation factor produced in the liver. Liver transplantation from hemophilia B donors is neither widely documented nor performed due to presumed risk of developing increased bleeding tendency in the recipient due to potential acquired factor IX deficiency. In this review, we present a case of liver and kidney transplantation from a donor with mild hemophilia B to a recipient with no history of hemophilia B and literature review. This is a relatively rare situation with only two other prior case reports of acquired Hemophilia B through liver transplantation noted in 2015. The 2 cases presented in the literature lead to acquired hemophilia B in liver transplant recipients since donors were not screened due to mild disease and low suspicion level. In our case, the donor was known to have mild Hemophilia B and the recipient had a rapid decline -thus it is imperative to weigh risks and benefits of transplantation from this donor population. While those individuals with mild hemophilia B disease (and low bleeding burden) should be considered as an alternative donor for liver transplantation, appropriate counseling should be done with the recipient about possible bleeding risks and OLT should only occur after patient consent. A multidisciplinary approach should involve hematology in case factor replacement therapy is needed post transplantation and for long term follow up.

118 Background: Patients with advanced cancer have high rates of hospitalizations as a result of their oncologic care. Furthermore, these patients receive aggressive end of life care despite evidence that aggressive end of life care does not improves quality of life or outcomes for patients and is associated with worse bereavement adjustment for caregivers. The American Society of Clinical Oncology has endorsed several indicators of aggressive end of life care, but most striking is intensive care unit (ICU) admission within 30 days before death. Methods: Adult oncology patients who died within 30 days of hospitalization and/or admitted to the ICU from 10/2018-3/2019 at an academic medical center were evaluated. The cohort was identified using ICD-10 codes, EMR systems support, and manual chart review. Patient demographic data, cancer type, stage, line of therapy, code status, advanced care plan, prior admissions as well as other clinical characteristics were collected. Results: In total, 180 patients were included for analysis; 106 of which were admitted to the ICU. Of patients admitted to the ICU, 58 patients died (54.7%). Mean ECOG performance status was 1.24. Average number of admissions 3 and 6 months prior to death was 0.71 and 1.26. Thirty six percent of patients were on first or second-line chemotherapy. 41.37% of patients who died in the ICU had prolonged length of stay (>1 week). Only 34.48% were known to palliative care prior to admission and 12.06% of patients had advanced care plans in place at time of hospitalization. Palliative care was consulted on 32.75% of patients who died in the ICU. Ninety Three percent had their code status changed prior to death. Conclusions: Despite established recommendations to support otherwise, at our institution there continues to be high utilization of ICU care near the end of life. Previous admissions and ECOG status are poor predictors of death in this cohort. The majority of patients had relapsed and refractory disease. There was a low rate of advanced care planning or palliative care involvement prior to the patient’s hospitalization. Further interventions are underway to improve end of life planning in order to improve our quality of care.
