Determinants of Bone Mass Accrual in Transgender and Gender Diverse Youth Undergoing Pubertal Suppression Therapy.

Introduction/background: Gender-affirming care for gender diverse and transgender (GDTG) youth includes puberty suppression with gonadotropin-releasing hormone agonists (GnRHa). Puberty is a critical period of bone mass accrual, and pubertal suppression may impact bone health. Previous studies have shown a decrease in areal bone mineral density (aBMD) Z-score while on puberty suppression.

Evaluation of propylene glycol methyl ether as a potential challenge agent for leak detection of liquid and headspace from closed system drug transfer devices using Fourier transform infrared spectroscopy.

Choosing an appropriate surrogate of hazardous drugs for use in testing Closed System Drug-Transfer Devices (CSTDs) is a challenging endeavor with many factors that must be considered. It was suggested that the compound propylene glycol methyl ether (PGME) may meet many of the criteria we considered important in a suitable surrogate. Criteria included sufficient volatility to evaporate from aqueous liquid leaks efficiently, a Henry's constant which produced sufficient vapor phase concentrations to make headspace leaks detectable, and suitability for detection using a low-cost detection system.

Method development for on-site monitoring of volatile organic compounds via portable TD-GC-MS: evaluation of the analytical performances of HAPSITE ER instrumentation and thermal desorption sampling media.

Determining worker exposure to hazardous volatile organic compounds (VOCs) in air at levels exceeding the Permissible Exposure Limits and Recommended Exposure Limits established by the U.S. federal agencies of Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH), respectively, will continue to be an important part of environmental and occupational health risk assessments.

Physician Assistant Educator Competencies.

The rapid expansion of physician assistant (PA) programs over the past decade has led to a shortage of experienced PA faculty. This has prompted many faculty development initiatives to help provide the skills needed by new faculty making the jump from clinical practice to academia. Faculty development is a key necessity in health professions education because many of the professionals attracted to the educator role are primarily trained as clinicians.

Thermoregulatory performance and habitat selection of the eastern box turtle ().

Environmental conditions may affect individual physiological processes that influence short-term performance and ultimately growth, survival and reproduction. As such, habitats selected by animals must provide suitable and adequate resources. Ectothermic species are highly dependent on climatic conditions and ambient temperatures that dictate body temperature regulation and in turn physiological processes.

Ultraviolet germicidal irradiation susceptibility of methicillin-resistant Staphylococcus aureus compared with methicillin-susceptible S. aureus.

Antibiotic misuse and overuse in both the healthcare and agricultural fields have dramatically increased the prevalence of antibiotic resistance in human pathogens. Two strains of methicillin-resistant Staphylococcus aureus (MRSA) (ATCC 43330 and a wild-type) and 1 strain of methicillin-susceptible S. aureus (ATCC 25923) were challenged (9 runs in triplicate) in a preliminary study with ultraviolet germicidal irradiation (UVGI) doses ranging from 0.

Effectiveness of selected surgical masks in arresting vegetative cells and endospores when worn by simulated contagious patients.

Objective: The objective of this study was to quantify the effectiveness of selected surgical masks in arresting vegetative cells and endospores in an experimental model that simulated contagious patients.

Setting: Laboratory.

Methods: Five commercially available surgical masks were tested for their ability to arrest infectious agents.

Learning outcomes and student-perceived value of clay modeling and cat dissection in undergraduate human anatomy and physiology.

Alternatives and/or supplements to animal dissection are being explored by educators of human anatomy at different academic levels. Clay modeling is one such alternative that provides a kinesthetic, three-dimensional, constructive, and sensory approach to learning human anatomy. The present study compared two laboratory techniques, clay modeling of human anatomy and dissection of preserved cat specimens, in the instruction of muscles, peripheral nerves, and blood vessels.

Does financial self-efficacy explain gender differences in retirement saving strategies?

Research indicates that women remain less financially prepared for retirement than are men. Little research has examined the gender difference in use of retirement plans. The present research assessed the gender difference in use of employer-sponsored and private retirement plans, and sought to account for this difference.
