Infertility is a devastating side effect of cancer treatment. Advances in fertility research have brought new preservation techniques to the forefront for women. The implication of this research in the field of pediatric oncology has not been reported. The objective of this study was to determine whether female adolescents with a diagnosis of cancer and(More)
The problems of fitting Gaussian frailties proportional hazards models for the subdistribution of a competing risk and of testing for center effects are considered. In the analysis of competing risks data, Fine and Gray proposed a proportional hazards model for the subdistribution to directly assess the effects of covariates on the marginal failure(More)
Pictorial health warnings on cigarette packages are a prominent and effective means of communicating the risks of smoking; however, there is little research on effective types of message content and socio-demographic effects. This study tested message themes and content of pictorial warnings in Mexico. Face-to-face surveys were conducted with 544 adult(More)
Most tobacco control efforts in western countries focus on the factory-made, mass-produced (FM) cigarette, whereas other tobacco products receive relatively little attention. Noncombusted tobacco products (i.e., referred to as smokeless tobacco), particularly Swedish-style snus, carry lower disease risks, compared with combusted tobacco products such as(More)
Allogeneic hematopoietic stem cell transplantation (SCT) may cure patients with hematologic malignancies, but it carries significant risks. Careful donor selection is an important component of the clinical transplantation decision-making process and includes evaluation of HLA typing and other criteria, the most controversial of which is parity. We examined(More)
Matching for HLA class I alleles, including HLA-C, is an important criterion for outcome of unrelated donor transplantation. However, haplotype-mismatched transplantations for myeloid malignancies, mismatched for killer immunoglobulin-like receptor (KIR) ligands in the graft-versus-host (GVH) direction, is associated with lower rates of graft-versus-host(More)
INTRODUCTION Lower socioeconomic status (SES) groups have higher rates of tobacco use, are less likely to successfully quit, and may also be less likely to intend or attempt to quit. However, results are inconsistent for some outcomes, and little is known about how socioeconomic disparities vary across countries and over time. METHODS This study examined(More)
This paper outlines the design features, data collection methods and analytic strategies of the International Tobacco Control (ITC) Four Country Survey, a prospective study of more than 2000 longitudinal respondents per country with yearly replenishments. This survey possesses unique features that sets it apart among surveys on tobacco use and cessation.(More)
OBJECTIVES To assess the types, rates, and risks of injury for male and female USAF recruits. DESIGN Outpatient visits for female (5250) and male recruits (8656) were collected and analyzed for rate of injury, types of injuries, and risk of injury throughout a 6-week training period. RESULTS One third of female recruits and one sixth of male recruits(More)
To compare the clinical outcomes of older (age > or =55 years) non-Hodgkin lymphoma (NHL) patients with younger NHL patients (<55 years) receiving autologous hematopoietic cell transplantation (HCT) while adjusting for patient-, disease-, and treatment-related variables, we compared autologous HCT outcomes in 805 NHL patients aged > or =55 years to 1949 NHL(More)
