Diagnostic Problem Solving in Male Collegiate Athletic Trainers
Context: Knowledge and experience may be important factors for understanding expertise based upon a clinician\u27s ability to select and execute an appropriate response as a clinician during injury evaluation.
Objective: To describe how collegiate male certified athletic trainers represent injury-evaluation domain knowledge during a situational interview using a think-aloud protocol.
Design: Qualitative.
Setting: National Collegiate Athletic Association Division I and II colleges in National Athletic Trainers\u27 Association District 3.
Patients or Other Participants: A total of 20 male certified athletic trainers (n = 10 with less than 2 years of experience in the college setting and n = 10 with at least 10 years of experience in the college setting) participated in the study.
Data Collection and Analysis: We collected data using a situational interview and questionnaire. Data were transcribed, reduced to meaningful units, and analyzed using verbal analysis procedures. Member checks, triangulation of data, field journaling, and peer-debriefing techniques were used to ensure trustworthiness of the data. Knowledge concepts were enumerated to describe differences between experts and novices.
Results: Compared with novices, experts had more knowledge concepts of patient history and predictions and fewer concepts of situation appraisal.
Conclusions: Expertise in athletic training shares traits with other areas in health care. Athletic training education and professional development may benefit from our understanding which cognitive processes differentiate expert practice. Future investigators should attempt to describe other settings and study diagnostic problem solving in a natural environment
Competing Perspectives During Organizational Socialization on the Role of Certified Athletic Trainers in High School Settings
When certified athletic trainers (ATCs) enter a workplace, their potential for professional effectiveness is affected by a number of factors, including the individual\u27s ability to put acquired knowledge, skills, and attitudes into practice. This ability may be influenced by the preconceived attitudes and expectations of athletes, athletes\u27 parents, athletic directors, physical therapists, physicians, and coaches.
Objective: To examine the perspectives of high school coaches and ATCs toward the ATC\u27s role in the high school setting by looking at 3 questions: (1) What are coaches\u27 expectations of ATCs during different phases of a sport season? (2) What do ATCs perceive their role to be during different phases of a season? and (3) How do coaches\u27 expectations compare with ATCs\u27 expectations
Socialization to gender roles and marriage among Egyptian adolescents
Using nationally representative survey data, this paper explores gender role socialization and attitudes toward marriage among unmarried Egyptian adolescents aged 16-19 years. We examine the daily activities of adolescent boys and girls, views about age at marriage and desirable qualities in a spouse, and various indicators of gender role attitudes including opinions about whether wives should defer to husbands, about sharing household decisionmaking, and about responsibility for domestic tasks. Our findings reflect strong gender differentiation: girls have much less free time than boys, are much less mobile, are much less likely to participate in paid work, and have heavier domestic responsibilities regardless of whether or not they are in school. Girls favor a later age at marriage for both sexes, but particularly for boys. Boys are significantly more likely than girls to favor educational inequality between spouses. While neither boys nor girls have particularly progressive gender role attitudes, girls are significantly more likely to express less traditional attitudes. Multivariate analyses indicate that girls’ and boys’ attitudes do not vary consistently and significantly by socioeconomic background; in particular, increased schooling does not always promote egalitarian attitudes. The implications of these findings for policies and programs are discussed
Practices and Perceptions of Family-Centered Care: A Cross-Sectional Survey of Secondary School Athletic Trainers
Family-centered care (FCC) includes collaboration between families and healthcare providers, the creation of flexible policies, and the family taking an active role in the delivery of care. Secondary school athletic trainers provide care for underage patients in school-based health systems, making them responsible for maintaining communication with parents, guardians, and/or caregivers. This cross-sectional survey investigated the extent to which athletic trainers (n = 205) include aspects of FCC in their daily secondary school clinical practice (current practices = CP) and whether they believe that aspect of care is necessary for FCC to be provided in athletic training (perceived necessary = PN) in their everyday practice using the Family-Centered Care Questionnaire-Revised tool. The total mean score for the CP scale (mean = 26.83 ± 4.36) was significantly lower ( ≤ 0.01) than the PN scale (mean = 35.33 ± 4.17). All FCC subscales compared between CP and PN were significantly different ( ≤ 0.01), with each being of higher importance than CP in athletic training. Data analysis revealed four themes related to enhancing FCC in secondary schools: limited education and resources, staffing and space concerns, non-technical skills, and social determinants of health. Attention should be placed on developing resources and interventions for secondary school athletic trainers to collaboratively work with children and their support systems
Women's Perceptions and Misperceptions of Male Circumcision: A Mixed Methods Study in Zambia.
Women's perceptions of male circumcision (MC) have implications for behavioral risk compensation, demand, and the impact of MC programs on women's health. This mixed methods study combines data from the first two rounds of a longitudinal study (n = 934) and in-depth interviews with a subsample of respondents (n = 45) between rounds. Most women correctly reported that MC reduces men's risk of HIV (64% R1, 82% R2). However, 30% of women at R1, and significantly more (41%) at R2, incorrectly believed MC is fully protective for men against HIV. Women also greatly overestimated the protection MC offers against STIs. The proportion of women who believed MC reduces a woman's HIV risk if she has sex with a man who is circumcised increased significantly (50% to 70%). Qualitative data elaborate women's misperception regarding MC. Programs should address women's informational needs and continue to emphasize that condoms remain critical, regardless of male partner's circumcision status
Prevalence of HIV-1 Drug Resistance among Women Screening for HIV Prevention Trials in KwaZulu-Natal, South Africa (MTN-009)
Background:A major concern with using antiretroviral (ARV)-based products for HIV prevention is the potential spread of drug resistance, particularly from individuals who are HIV-infected but unaware of their status. Limited data exist on the prevalence of HIV infection or drug resistance among potential users of ARV-based prevention products.Methods:A cross-sectional study of reproductive-aged women who presented to screen for an HIV prevention trial was conducted at 7 clinical sites in Durban, South Africa. CD4+T cell counts, HIV-1 RNA levels and population sequencing of the protease and reverse transcriptase genes were performed for all women with 2 positive HIV rapid tests. Resistance mutations were identified using the Stanford Calibrated Population Resistance Tool.Results:Of the 1073 evaluable women, 400(37%) were confirmed as HIV-infected. Of those, plasma HIV-1 RNA was detectable in 365/400(91%) and undetectable(200 copies/ml) analyzed for drug resistance, 26(7.4%) had nucleoside reverse transcriptase inhibitor (NRTI), non-nucleoside reverse transcriptase inhibitor (NNRTI) or protease inhibitor (PI) drug resistance mutations. Among those with resistance, 18/26 participants(62%) had single-class NNRTI resistance and 5/26(19%) had dual-class NRTI/NNRTI. Major mutations in reverse transcriptase included K65R(n = 1), L74I(n = 1), K103N(n = 19), V106M(n = 4), Y181C(n = 2), M184V(n = 4), and K219E/R(n = 2). Major PI-resistance mutations were rare: M46L(n = 1) and I85V(n = 1). All participants were infected with subtype C virus, except one infected with subtype A.Conclusions:In women from Durban, South Africa screening for an HIV prevention trial, the HIV prevalence was high (37%) and HIV drug resistance prevalence was above 5%. This study highlights the potential challenges faced when implementing an ARV-based prevention product that overlaps with first-line antiretroviral therapy. Effective screening to exclude HIV infection among women interested in uptake of ARV-based HIV prevention will be essential in limiting the spread of ARV resistance
A eta-alpha and A eta-beta peptides impair LTP ex vivo within the low nanomolar range and impact neuronal activity in vivo
Background:
Amyloid precursor protein (APP) processing is central to Alzheimer’s disease (AD) etiology. As early cognitive alterations in AD are strongly correlated to abnormal information processing due to increasing synaptic impairment, it is crucial to characterize how peptides generated through APP cleavage modulate synapse function. We previously described a novel APP processing pathway producing η-secretase-derived peptides (Aη) and revealed that Aη–α, the longest form of Aη produced by η-secretase and α-secretase cleavage, impaired hippocampal long-term potentiation (LTP) ex vivo and neuronal activity in vivo.
Methods:
With the intention of going beyond this initial observation, we performed a comprehensive analysis to further characterize the effects of both Aη-α and the shorter Aη-β peptide on hippocampus function using ex vivo field electrophysiology, in vivo multiphoton calcium imaging, and in vivo electrophysiology.
Results:
We demonstrate that both synthetic peptides acutely impair LTP at low nanomolar concentrations ex vivo and reveal the N-terminus to be a primary site of activity. We further show that Aη-β, like Aη–α, inhibits neuronal activity in vivo and provide confirmation of LTP impairment by Aη–α in vivo.
Conclusions:
These results provide novel insights into the functional role of the recently discovered η-secretase-derived products and suggest that Aη peptides represent important, pathophysiologically relevant, modulators of hippocampal network activity, with profound implications for APP-targeting therapeutic strategies in AD
What Are the Barriers and Motivators to Exercise in 50-65 Year-Old Adults?
Introduction. The benefit of exercise in adults has been well established. Research has demonstrated improved cardiovascular health, decreased bone fractures, and increased mental capacity. While the benefits of exercise has clearly been demonstrated, personal barriers to exercise are yet to be fully elucidated. Thus, in collaboration with the YMCA, this study aimed to clarify barriers to exercise in 50-65 year-old adults.https://scholarworks.uvm.edu/comphp_gallery/1085/thumbnail.jp
