Thiotepa‐based versus total body irradiation‐based myeloablative conditioning prior to allogeneic stem cell transplantation for acute myeloid leukaemia in first complete remission: a retrospective analysis from the Acute Leukemia Working Party of the European Group for Blood and Marrow Transplantation

Thiotepa is an alkylating compound with an antineoplastic and myeloablative activity and can mimic the effect of radiation. However, it is unknown whether this new regimen could safely replace the long‐established ones. This retrospective matched‐pair analysis evaluated the outcome of adults with acute myeloid leukaemia in first complete remission who received myeloablative conditioning either with a thiotepa‐based (n = 121) or a cyclophosphamide/total body irradiation‐based (TBI; n = 358) regimen for allogeneic hematopoietic stem cell transplantation from an HLA‐matched sibling or an unrelated donor. With a median follow‐up of 44 months, the outcome was similar in both groups. Acute graft‐versus‐host disease grade II‐IV was observed in 25% after thiotepa‐containing regimen versus 35% after TBI (P = 0.06). The 2‐yr cumulative incidence of chronic graft‐versus‐host disease was 40.5% for thiotepa and 41% for TBI (P = 0.98). At 2 yrs, the cumulative incidences of non‐relapse mortality and relapse incidence were 23.9% (thiotepa) vs. 22.4% (TBI; P = 0.66) and 17.2% (thiotepa) vs. 23.3% (TBI; P = 0.77), respectively. The probabilities of leukaemia‐free and overall survival at 2 yrs were not significantly different between the thiotepa and TBI groups, at 58.9% vs. 54.2% (P = 0.95) and 61.4% vs. 58% (P = 0.72), respectively. Myeloablative regimens using combinations including thiotepa can provide satisfactory outcomes, but the optimal conditioning remains unclear for the individual patient in this setting.     

Trajectory of human movement during sit to stand: a new modeling approach based on movement decomposition and multi-phase cost function

The ability to predict accurately the weights of objects is essential for skilled and dexterous manipulation. A potentially important source of information about object weight is through the observation of other people lifting objects. Here, we tested the hypothesis that when watching an actor lift an object, people naturally learn the object’s weight and use this information to scale forces when they subsequently lift the object themselves. Participants repeatedly lifted an object in turn with an actor. Object weight unpredictably changed between 2 and 7 N every 5th to 9th of the actor’s lifts, and the weight lifted by the participant always matched that previously lifted by the actor. Even though the participants were uninformed about the structure of the experiment, they appropriately adapted their lifting force in the first trial after a weight change. Thus, participants updated their internal representation about the object’s weight, for use in action, when watching a single lift performed by the actor. This ability presumably involves the comparison of predicted and actual sensory information related to actor’s actions, a comparison process that is also fundamental in action.     

Psychosocial Profiles among Persons with Substance Use Disorder Undergoing Islamic-Based Inabah Program in Kelantan,Malaysia

Psychosocial profiles among a convenience sample of 37 Malay Muslim participants of Inabah program were measured using the Psychological Measure of Islamic Religiousness (PMIR). Data were analysed using SPSS 23.0. Positive relations with others emerged as the best-scored subscale whereas anger trait and depressed mood were minimal. Single and divorced respondents demonstrated significantly higher score for purpose in life. More favorable social desirability was reported by participants with no previous treatment. Less anger and depression were expressed by those not detained before. Essentially, psychosocial status of persons with substance use disorder undergoing Inabah program was moderate with some influences of sociodemographic factors.     

Clinical characteristics and outcome of children stung by scorpion

Scorpion envenomation is a health problem in children in tropical and subtropical regions. The aim of this study was to evaluate demographic and clinical characteristics as well as outcomes in referred children to Assiut University Children Hospital during the year 2012 with a history of scorpion sting. The medical files of these patients were reviewed retrospectively for demographic data, time and site of biting, and clinical manifestations. Laboratory investigations of the patients were reviewed for complete blood count (CBC), liver function tests, creatinine phosphokinase (CPK), lactate dehydrogenase (LDH), arterial blood gases, and serum electrolytes. Results showed 111 children with a history of scorpion sting; 69 males and 42 females with a median age of 5 years. Out of the studied patients, 53.2 % were classified as class III of clinical severity with recorded pulmonary edema in 33.3 %, cardiogenic shock in 46.8 %, and severe neurological manifestations in 22.8 %. Twelve patients (10.8 %) were classified as class II with mild systemic manifestations, and 36 % of the patients were classified as class I with only local reaction. Outcomes of these patients were discharge without sequelae in 55.8 %, discharge with sequelae in 26.1 %, and death in 18.1 %. Conclusion: more than half of stung children had a severe clinical presentation and about one fifth died. Aggressive treatment regimens are recommended for such patients to improve the outcome.     

Lactone-rich fraction from Vernonia blumeoides: antitrypanosomal activity and alleviation of the parasite-induced anemia and organ damage

The anti-Trypanosoma brucei brucei activity in vitro and in vivo of a lactone-rich fraction of Vernonia blumeoides leaves (VBLF) and its potential in alleviating trypanosome-induced anemia and organ damage were investigated. Gas chromatography–mass spectrometry (GC–MS) analysis of VBLF revealed the presence of a number of lactone-containing compounds. In an in vitro study, VBLF showed concentration-dependent activity and was further used to treat T. brucei brucei-infected rats. The VBLF treatments, especially at 300 mg/kg body weight (BW), significantly (P < 0.05) kept the parasites reduced during the entire experimental period compared with the infected untreated group. At the end of the experiment, the trypanosome-induced anemia and hepatic damage were significantly (P < 0.05) alleviated in all the VBLF treatment groups, but renal damage was only prevented in the 200 and 300 mg/kg BW treatment groups. Furthermore, the trypanosome-induced increase in the relative weights of liver, spleen and kidney were significantly (P < 0.05) alleviated by the 300 mg/kg BW VBLF treatment. It was concluded that orally administered VBLF, especially at 300 mg/kg BW, possessed antitrypanosomal activity and could alleviate parasite-induced anemia and organ damage.     

Selecting a Medical School Advisor

Having an advisor offers medical students many advantages, including increased likelihood of matching into their top choices. Interestingly, students who choose emergency medicine (EM) as a specialty are more likely to seek advising. However, finding and optimally utilizing an EM faculty advisor is often challenging for the medical student. In this article, we tackle the different ways to seek advising, including the ‘virtual advisor program’ implemented by the Society for Academic Emergency Medicine, the ‘e-Advisor Program’ instigated by the Clerkship Director in EM Group, the ‘member exclusive mentorship program’ of the Emergency Medicine Residency Association, as well as peer-based mentoring. More so, we discuss the consensus recommendations developed by the Student Advising Task Force to guide both students planning to apply to EM and their advisors to ensure high-caliber advising.     

Outcome of patients with systemic light chain amyloidosis with concurrent renal and cardiac involvement

Cardiac involvement in systemic light chain amyloidosis (AL) is generally associated with a worse outcome, especially if other organs are also involved. We sought to determine whether concurrent cardiac and renal involvement were associated with a worse outcome than either organ alone. We identified 129 patients with AL, who received high‐dose chemotherapy followed by autologous hematopoietic stem cell transplantation (auto‐HCT) at our institution between 1997 and 2014. Ninety‐nine patients had either renal (group 1: n = 62, 62%), cardiac (group 2: n = 20, 20%), or both cardiac and renal (group 3: n = 17, 17%) involvement. The overall hematological response rate (CR+VGPR+PR) post‐auto‐HCT in groups 1, 2, and 3 was 69%, 74% and 82%, respectively (P = 0.62). Overall, organ response in groups 1, 2, and 3 was 39%, 42%, and 70%, respectively. The median PFS from auto‐HCT in groups 1, 2, and 3 was not reached (NR), 13.3 and 21 months, respectively (P = 0.02). The median OS in groups 1, 2, and 3 was 120, 46, and 60 months, respectively (P = 0.1). In conclusion, median PFS and OS in patients with concurrent cardiac and renal AL were comparable to patients with cardiac AL only, but worse than patients with renal AL.     

A Financial Plot to Reduce the Burden of Medical School Tuition Fees

Tuition fees for medical school are continuously and riotously increasing. This upsurge is amassing debts on the backs of students. In the class of 2018, 75% finished medical school with an outstanding balance of $196,520, on average—a $5826 increase from 2017. Tuition fees differ in terms of the ownership of the medical school (public vs. private) and according to the medical student residence status (in-state or out-of-state). It is critical that students arrange a long-term budget that shows them where they stand: in surplus or in deficit. Students may classify expenditures into two groups: “fixed” and “variable,” where they can manipulate the variable expenses to fit into their budget. To pay for their tuition, medical students have four possibilities: cash, scholarships and grants, service-obligation scholarships, and loans. Loans are the most common alternatives, and so there are Traditional Repayment Plans and Income-Driven Repayment Plans. This article serves to provide medical students with attainable alternatives for funding their education and for repaying their debts.
