Article Synopsis
  • Successful allogeneic hematopoietic stem cell transplantation (alloHSCT) requires a specific dose of total nucleated cells (TNCs), with 2 × 10 TNCs per kg of recipient weight as the minimum for effective engraftment.
  • An algorithm that takes into account baseline donor characteristics can help in predicting TNC concentrations, which vary significantly across donors.
  • Analysis of donor data revealed that factors like higher body mass index, younger age, male sex, and certain preharvest blood counts strongly correlate with higher TNC concentrations, and two predictive models, LASSO and OLS, showed the best fit for this prediction.

In recent years, the availability of software that is targeted toward the general public and designed to assist in the diagnosis and treatment of mental illness or to promote general mental health has expanded greatly. Regulation of more traditional health care providers and health care-associated devices is well established by statute, regulatory guidelines, and common law precedents. Applications (apps), in contrast, pose a novel regulatory challenge.

Research suggests that students experience high levels of sexual assault, but studies addressing how they differ in their experiences from other sexual assault victims are virtually nonexistent. To address this gap, information was collected from consecutive individuals, aged 16 years or older, presenting to one of 7 hospital-based sexual assault treatment centers in Ontario from 2005 to 2007. Of the 882 victims seen during the study period, 32% were students.

Background: Lymphangioleiomyomatosis (LAM) is a progressive, cystic lung disease in women; it is associated with inappropriate activation of mammalian target of rapamycin (mTOR) signaling, which regulates cellular growth and lymphangiogenesis. Sirolimus (also called rapamycin) inhibits mTOR and has shown promise in phase 1-2 trials involving patients with LAM.

Methods: We conducted a two-stage trial of sirolimus involving 89 patients with LAM who had moderate lung impairment--a 12-month randomized, double-blind comparison of sirolimus with placebo, followed by a 12-month observation period.

The purpose of this study was to determine which persons reporting sexual assault to a hospital-based treatment centre may have been covertly drugged and to provide information about whether a sexual assault may have occurred. Each consecutive adolescent and adult presenting at a sexual assault treatment centre was screened for drug-facilitated sexual assault (DFSA). Urine was collected and tested for central nervous system active drugs.

Knowing the characteristics associated with child exposure to spousal abuse could aid in early identification of at-risk children. The purpose of our study is to determine possible factors associated with child witnessing of intimate partner violence (IPV) in Canada using data from the 1999 General Social Survey, a representative telephone survey of Canadians aged 15 years and older. Respondents reporting IPV in the five years prior to the survey were asked whether a child had witnessed the incident.

Introduction: Intimate partner violence (IPV) is experienced by women of all ethnoracial backgrounds. Despite the serious adverse impacts of IPV on women's lives, many abused women do not seek help. The main objective of this paper was to determine whether a woman's racial minority status was a significant predictor of help-seeking for IPV after controlling for other factors associated with help-seeking.

Objective: To determine the importance of role overload (the extent to which a person feels overwhelmed by her total responsibilities) relative to other known social determinants of women's mental health.

Methods: A Canadian national, random sample, cross-sectional telephone survey in 2003 assessed the association among role overload, types and quality of roles (parent, employee, spouse), sociodemographics, and mental health (using the SF-12) using linear regression. Analysis included 716 women aged 25-54 who indicated that their youngest child living in the household was aged < or =17 years.

Objective: Women are known to use more psychotropic medications than men which may be linked to women's greater exposure to intimate partner violence (IPV).

Method: The use of medications for sleep, depression and anxiety in adults in the 1999 Canadian General Social Survey was assessed. Rates of medication use by adults exposed to IPV (physical, sexual, emotional and financial) were compared to rates of those reporting no IPV.

Although it is commonly accepted that interpersonal violence (IntPV) leads to adverse health consequences, the available data are far from decisive. To test the hypothesized link, the authors devised an evidence-based strategy to determine the data quality in studies purporting to link IntPV and some medically unexplained disorders in women (irritable bowel syndrome, chronic pelvic pain, fibromyalgia/chronic fatigue, and other chronic pain syndromes). English language studies with control groups of unaffected women were assessed for the quality of their methodologies.
