BACKGROUND: After decades of practice of pediatric cardiac surgery, postoperative bleeding due to the immaturity of hemostasis, hemodilution, and hypothermia remains a concern. Recently, a new approach for adult coagulopathy after bypass has emerged. Prothrombin complex concentrates (PCCs), designed to treat bleeding in hemophilia patients, are safely and efficiently used off label for hemorrhage after bypass. However, optimal dosing, indications and contraindications, and laboratory tests to assess the efficacy of PCC use in children have not yet been established...

BACKGROUND: Pulmonary artery (PA) aneurysms are rare and have been reported only in case reports or small series. We reviewed our experience with surgical repair of PA aneurysms. METHODS: We reviewed all patients with a true PA aneurysm undergoing cardiac operations between 1995 and 2015. We excluded aneurysms and pseudoaneurysms related to right ventricular outflow tract patches or previous conduits. RESULTS: There were 38 patients (24 women [63%]; mean age, 46 ± 15 years), and 14 patients (37%) were asymptomatic...

Purpose T-cell-replete HLA-haploidentical donor hematopoietic transplantation using post-transplant cyclophosphamide was originally described using bone marrow (BM). With increasing use of mobilized peripheral blood (PB), we compared transplant outcomes after PB and BM transplants. Patients and Methods A total of 681 patients with hematologic malignancy who underwent transplantation in the United States between 2009 and 2014 received BM (n = 481) or PB (n = 190) grafts. Cox regression models were built to examine differences in transplant outcomes by graft type, adjusting for patient, disease, and transplant characteristics...

BRCA deficiency predisposes to the development of invasive breast cancer. In BRCA mutation carriers this risk can increase up to 80%. Currently, bilateral prophylactic mastectomy and prophylactic bilateral salpingo-oophorectomy are the only preventive, albeit radical invasive strategies to prevent breast cancer in BRCA mutation carriers. An alternative non-invasive way to prevent BRCA1-associated breast cancer may be local prophylactic treatment via the nipple.Using a non-invasive intraductal (ID) preclinical intervention strategy, we explored the use of combined cisplatin and poly (ADP)-ribose polymerase 1 (PARP1) inhibition to prevent the development of hereditary breast cancer...

Oligogalacturonides (OGs) are known for their powerful ability to stimulate the plant immune system but little is known about their mode of action in pea (Pisum sativum). In the present study, we investigated the elicitor activity of two fractions of OGs, with polymerization degrees (DPs) of 2-25, in pea against Aphanomyces euteiches. One fraction was nonacetylated (OGs - Ac) whereas the second one was 30% acetylated (OGs + Ac). OGs were applied by injecting the upper two rachises of the plants at three- and/or four-weeks-old...

Celiac crisis is a rare life-threatening presentation of celiac disease that manifests as profuse diarrhea, hypoproteinemia, and severe metabolic disturbances. It may be precipitated by a general immune stimulus such as surgery, infection, or pregnancy. We report the case of a 26-year-old woman who presented with a celiac crisis, potentially triggered by a preceding urinary tract infection. Metabolic derangement is caused by malabsorption and profuse diarrhea, which can be unremitting unless the celiac crisis is recognized, and treatment with gluten restriction is initiated...

Sameh Ahmed, Noha N Atia
Selective and fast chromatographic method was essential for the determination of triptans, selective serotonin receptor (5-HT1) agonists, in biological specimens. However, selective chromatographic separation of these highly basic drugs is a challenging problem on silica-based stationary phases. Zirconia-based stationary phases have been introduced as an efficient alternative for silica-based columns offering unique stability, selectivity, and retention ability for various classes of drugs. Herein, a new selective, fast and reproducible high performance liquid chromatographic method (HPLC) was developed and validated for the determination of four triptans in plasma samples namely; Sumatriptan (SMT), Zolmitriptan (ZLT), Eletriptan (ELT) and Rizatriptan (RZT)...

Xenon is known to be a very efficient anesthetic gas but its cost prohibits the wider use in medical industry and other potential applications. It has been shown that Xe recovery and recycle from anesthetic gas mixture can significantly reduce its cost as anesthetic. The current technology uses series of adsorbent columns followed by low temperature distillation to recover Xe, which is expensive to use in medical facilities. Herein, we propose a much simpler and more efficient system to recover and recycle Xe from exhale anesthetic gas mixture at room temperature using metal organic frameworks...

Systemic mastocytosis (SM) is a condition associated with clonal neoplastic proliferation of mast cells. In up to 40% of systemic mastocytosis cases, an associated clonal hematological disease of non-mast cell lineage, such as acute myeloid leukemia (AML), is diagnosed before, simultaneously with, or after the diagnosis of SM. Herein, we report a case of a 30-year-old man diagnosed with AML with inv(16) (p13;q22) CBFB:MYH11. Associated mastocytosis was not noted at diagnosis and was only detected in the bone marrow at time of remission after successful chemotherapy...
