ROC curve analyses revealed total amount of phenylephrine injected and duration of erection were acceptable and excellent predictors of need for shunt procedures with area under the curves of 0.72 and 0.90, respectively. Optimal cut-off values for each were found to be 950 mcg and 15.5 hours.

Our study suggests that patients who require greater than 950 mcg of total phenylephrine or present with erections lasting greater than 15.5 hours are significantly more likely to require corporoglandular shunting and should be counseled appropriately as such.

The two-year rodent bioassays serve as experimental vehicles to determine the high-dose cancer risks in animals and then to predict, by extrapolation, the number of carcinogen-induced tumors (tumor incidence) that will arise during the lifespans of humans who are exposed to environmental carcinogens at doses typically orders of magnitude below those applied in the rodent assays. An integrated toxicological analysis is conducted herein to reconsider an alternative and once-promising approach, tumor latency, for estimating carcinogen-induced cancer risks at low doses. Tumor latency measures time-to-tumor following exposure to a carcinogen, instead of tumor incidence. Evidence for and against the c premises of low-dose linearity and updating the current practices of cancer risk assessment to include the concept of carcinogen thresholds.Approximately 7% of unrelated hematopoietic stem cell donors are asked to donate stem cells a subsequent time to the same or a different recipient. Recent studies have shown that donation-related symptoms for second donations are similar to those for the first donation. Little is known about differences in stem cell mobilization and yields for subsequent peripheral blood stem cell (PBSC) and bone marrow (BM) collections. We hypothesized that CD34+ cell yields and total nucleated cell (TNC) concentrations for subsequent PBSC or BM donations are lower than those at the first donation. We also evaluated the factors influencing stem cell yields in healthy unrelated second-time donors. Data were gathered from the Center for International Blood and Marrow Transplant Research database on 513 PBSC and 43 BM donors who donated a second time between 2006 and 2017 through the National Marrow Donor Program. Among the second-time PBSC donors, we found significantly lower preapheresis peripheral blood CD34+ cell counts (68.6 × 106/L versus 73.9 × 106/L; P = .03), and collection yields (556 × 106 versus 608 × 106; P = .02) at the second donation compared to the first. This decrease at the subsequent donation was associated with a shorter interdonation interval, lower body mass index (BMI), and a lower total G-CSF dose. In most instances, suboptimal mobilizers at their first donation donated suboptimal numbers of stem cells at their subsequent donations. Among repeat BM donors, the TNC concentration was lower at the second donation. The small size of this group precluded additional analysis. Overall, when considering repeat donations, increasing the interdonation intervals and evaluating for BMI changes should be considered to optimize stem cell yields. selleck kinase inhibitor Some of these parameters may be improved by increasing G-CSF dose in PBSC donors within permissible limits.There are limited treatment options and substantial unmet needs for adult patients with relapsed or refractory diffuse large B cell lymphoma (r/r DLBCL) in Japan. In 2019, tisagenlecleucel, a CD19-directed chimeric antigen receptor T cell therapy, was approved for r/r DLBCL in Japan. The efficacy and safety of tisagenlecleucel were demonstrated in the pivotal phase II single-arm JULIET trial. The objective of the current study was to assess the cost-effectiveness of tisagenlecleucel treatment strategy versus current standard of care (salvage chemotherapy treatment strategy) for the treatment of patients with r/r DLBCL in Japan. A three-state partitioned survival model was constructed from a Japanese public healthcare payer's perspective, with the following three health states progression-free survival, progressive/relapsed disease, and death. Because the tisagenlecleucel arm included patients who did or did not receive the infusion, a decision-tree structure was used to partition patients based on their infusL compared to salvage chemotherapy treatment strategy from a Japanese public healthcare payer's perspective.Consolidation using high-dose chemotherapy with autologous stem cell transplantation (ASCT) is an important component of frontline therapy for children with high-risk neuroblastoma. The optimal preparative regimen is uncertain, although recent data support a role for busulfan/melphalan (BuMel). The Children's Oncology Group (COG) conducted a trial (ANBL12P1) to assess the tolerability and feasibility of BuMel ASCT following a COG induction. Patients with newly diagnosed high-risk neuroblastoma who did not progress during induction therapy and met organ function requirements received i.v. busulfan (every 24 hours for 4 doses based on age and weight) and melphalan (140 mg/m2 for 1 dose), followed by ASCT. Busulfan doses were adjusted to achieve to an average daily area under the curve (AUC) less then 5500 µM × minute. The primary endpoint was the occurrence of severe sinusoidal obstruction syndrome (SOS) or grade ≥4 pulmonary complications within the first 28 days after completion of consolidation therapy. A total of 146 eligible patients were enrolled, of whom 101 underwent BuMel ASCT. The overall incidence of protocol-defined unacceptable toxicity during consolidation was 6.9% (7 of 101). Six patients (5.9%) developed SOS, with 4 (4%) meeting the criteria for severe SOS. link2 An additional 3 patients (3%) experienced grade ≥4 pulmonary complications during consolidation. link3 The median busulfan AUC was 4558 µM × min (range, 3462 to 5189 µM × minute) for patients with SOS and 3512 µM × min (2360 to 5455 µM × minute) (P = .0142). No patients died during consolidation. From the time of study enrollment, the mean 3-year event-free survival for all 146 eligible patients was 55.6 ± 4.2%, and the mean 3-year overall survival was 74.5 ± 3.7%. The BuMel myeloablative regimen following COG induction was well tolerated, with acceptable pulmonary and hepatic toxicity.

The increasing use of "kidney"-nourishing Traditional Chinese Medicine (TCM) like Er-xian decoction (EXD) for management of menopausal symptoms and osteoporosis has aroused concerns about their safety, and whether they interact with prescription drugs as both of them act via estrogen receptors (ERs) and regulate serum estradiol.

The present study aimed to evaluate whether EXD selectively exerted estrogenic activities and interacted with Selective Estrogen Receptor Modulators (SERMs).

In vivo, mature ovariectomized (OVX) rats were administrated with EXD or combined treatment of EXD and SERMs for 12 weeks. The tissue-selective effect of EXD and its interaction of SERMs were studied in four estrogen sensitive tissues, bone, brain, breast and uterus. In vitro, the interaction of extracts of EXD-treated serum and SERMs in four ER-positive cell lines.

In OVX rats, EXD selectively alleviated estrogen deficiency-induced changes in the bone and brain without inducing any estrogenic effects in the breast or utereatment of EXD and SERMs did not hamper the beneficial effects of SERMs on the bone or brain but appeared to moderate the estrogenic effect of SERMs in the uterus.

The strongly scented genus Adenosma R. Brown (Plantaginaceae) comprises between 26 and 29 species with mainly southeast Asian distributions. Several species are used traditionally, mostly in Asian countries, for medicinal purposes including the treatment of colds and tumors, as well as stomach, liver, and skin disorders. Some species are also used as insecticides and/or insect repellents against mosquitoes or fleas.

Although the potential health benefits of Adenosma spp. are not yet well-known or well-studied in modern medicine, the aim of the present review is to provide a critical appraisal of the current state of knowledge regarding the geographical distribution, traditional uses, phytochemistry, phytochemicals and biological properties of Adenosma spp.

Electronic databases (Web of Science, Science Direct, Google Scholar, Scifinder, Microsoft Academic, eFloras), Biodiversity Heritage Library (BHL), and the China National Knowledge Infrastructure (CNKI), were searched using the key words "Adenosma", "essential oils, particularly terpenoids, and the crude extracts have valuable bioactive properties.
