Mechanisms for the Association between Traditional Masculine Ideologies and Rape Myth Acceptance among College Men

We explored mechanisms for the relationship between traditional masculine ideologies and rape myth acceptance. We hypothesized that locus of control would serve as a mediator for victim precipitation rape myths, while negative attitudes toward women would serve as a mediator for victim masochism and victim fabrication rape myths. Using a sample of 100 male college students, the results indicated that negative attitudes toward women mediated the relationship between traditional masculine ideologies and all three types of rape myths, but locus of control did not serve as a mediator for any. Implications and directions for future research are discussed

Vitamin A Status of Women and Children in Yaoundé and Douala, Cameroon, is Unchanged One Year after Initiation of a National Vitamin A Oil Fortification Program.

Vitamin A (VA) fortification of cooking oil is considered a cost-effective strategy for increasing VA status, but few large-scale programs have been evaluated. We conducted representative surveys in Yaoundé and Douala, Cameroon, 2 years before and 1 year after the introduction of a mandatory national program to fortify cooking oil with VA. In each survey, 10 different households were selected within each of the same 30 clusters (n = ~300). Malaria infection and plasma indicators of inflammation and VA (retinol-binding protein, pRBP) status were assessed among women aged 15-49 years and children aged 12-59 months, and casual breast milk samples were collected for VA and fat measurements. Refined oil intake was measured by a food frequency questionnaire, and VA was measured in household oil samples post-fortification. Pre-fortification, low inflammation-adjusted pRBP was common among children (33% <0.83 µmol/L), but not women (2% <0.78 µmol/L). Refined cooking oil was consumed by >80% of participants in the past week. Post-fortification, only 44% of oil samples were fortified, but fortified samples contained VA concentrations close to the target values. Controlling for age, inflammation, and other covariates, there was no difference in the mean pRBP, mean breast milk VA, prevalence of low pRBP, or prevalence of low milk VA between the pre- and post-fortification surveys. The frequency of refined oil intake was not associated with VA status indicators post-fortification. In sum, after a year of cooking oil fortification with VA, we did not detect evidence of increased plasma RBP or milk VA among urban women and preschool children, possibly because less than half of the refined oil was fortified. The enforcement of norms should be strengthened, and the program should be evaluated in other regions where the prevalence of VA deficiency was greater pre-fortification

Maternal plasma DHA levels increase prior to 29 days post-LH surge in women undergoing frozen embryo transfer: a prospective, observational study of human pregnancy

Context: Docosahexaenoic acid (DHA) is an important fatty acid required for neurological development but its importance during early fetal neurological organogenesis is unknown. Objective: To assess plasma fatty acid changes in early pregnancy in women undergoing natural cycle-frozen embryo transfer as a means of achieving accurately-timed periconceptual sampling. Design: Women undergoing frozen embryo transfer were recruited and serial fasting blood samples were taken pre-luteinising hormone (LH) surge, and at days 18, 29 and 45 post-LH surge and fatty acids were analysed using gas chromatography. Setting: Assisted Conception Unit, Glasgow Royal Infirmary, Scotland Main outcome measures: Plasma fatty acid concentrations, influence of twin pregnancies on DHA plasma concentration. Results: In pregnant women, there was a rapid, early increase in the maternal rate of change of plasma DHA concentration observed by 29 days post-LH surge (mean±SD, from 0.1±1.3 to 1.6±2.9 nmol DHA per mL plasma per day). This early pressure to increase plasma DHA concentration was further emphasised in twin pregnancies where the increase in DHA concentration over 45 days was two-fold higher than in singleton pregnancies (mean±SD increase, 74±39 nmol/mL versus 36±40 nmol/mL). An index of delta-6 desaturase activity increased 30% and positively correlated with the rate of change of DHA concentration between day 18 and 29-post LH surge (R-squared adjusted = 41%, P=0.0002). DHA was the only fatty acid with a continual accelerated increase in plasma concentration and a positive incremental area under the curve (mean±SD, 632±911 nmol/mL x day) over the first 45 days of gestation. Conclusions: An increase in maternal plasma DHA concentration is initiated in human pregnancy prior to neural tube closure which occurs at 28 days' gestation

Pathologic Thr 175 tau phosphorylation in CTE and CTE with ALS

Objective To investigate whether chronic traumatic encephalopathy (CTE) and CTE with amyotrophic lateral sclerosis (CTE-ALS) exhibit features previously observed in other tauopathies of pathologic phosphorylation of microtubule-associated protein tau at Thr 175 (pThr 175 tau) and Thr 231 (pThr 231 tau), and glycogen synthase kinase-3β (GSK3β) activation, and whether these pathologic features are a consequence of traumatic brain injury (TBI). Methods Tau isoform expression was assayed by western blot in 6 stage III CTE cases. We also used immunohistochemistry to analyze 5 cases each of CTE, CTE-ALS, and 5 controls for expression of activated GSK3β, pThr 175 tau, pThr 231 tau, and oligomerized tau within spinal cord tissue and hippocampus. Using a rat model of moderate TBI, we assessed tau pathology and phospho-GSK3β expression at 3 months postinjury. Results CTE and CTE-ALS are characterized by the presence of all 6 tau isoforms in both soluble and insoluble tau isolates. Activated GSK3β, pThr 175 tau, pThr 231 tau, and oligomerized tau protein expression was observed in hippocampal neurons and spinal motor neurons. We observed tau neuronal pathology (fibrillar inclusions and axonal damage) and increased levels of pThr 175 tau and activated GSK3β in moderate TBI rats. Conclusions Pathologic phosphorylation of tau at Thr 175 and Thr 231 and activation of GSK3β are features of the tauopathy of CTE and CTE-ALS. These features can be replicated in an animal model of moderate TBI

Rural Low-income Families Speak: Living in Rural Louisiana (Research Information Sheet # 109)

After the passage of federal welfare reform legislation in 1996, faculty from land-grant universities organized to conduct a study of the legislation’s impact on rural families. The project began in 1998 and runs through 2008. The intent was to provide policymakers and program directors with up-to-date information about the ability of rural, low-income families to be economically self sufficient. The objectives of this project are included in this publication.https://digitalcommons.lsu.edu/agcenter_researchinfosheets/1000/thumbnail.jp

Health communication and adolescents: What do their emails tell us?

This is a pre-copy-editing, author-produced PDF of an article accepted for publication in Family Practice following peer review. The definitive publisher-authenticated version Brown, B.J. et al (2008) Health communication and adolescents: What do their emails tell us? Family Practice, 25, pp.304-311. is available online at: http://dx.doi.org/10.1093/fampra/cmn029Background. It is widely known that barriers exist in communication between adolescents and health professionals. However, little is known about the actual language used by young people articulating such difficulties and whether email might allow them to overcome these problems. Objectives. The aims of this study were to investigate concerns and difficulties relating to communication among adolescents seeking online health advice. Methods. The study design was a corpus linguistic analysis of a million-word adolescent health email database based on 62 794 emails from young people requesting health advice from a prominent UK-hosted and doctor-led website. Results. Young people reported various concerns about their health. They described numerous difficulties in disclosing such concerns to other people, in particular to parents and doctors. However, they readily expressed their concerns by email, displaying elevated levels of directness, particularly in relation to potentially sensitive or embarrassing topics. Conclusion. Email has the potential to facilitate and supplement face-to-face consultations with health professionals. Increased adoption of email by health providers may be an efficient means of engaging with a generation often reluctant to access more traditional health care services and thus encourage them to enter the primary care setting more readily

The Relationship Between Health and Movement Screens and Field-Based Physical Fitness Tests in Reserve Officer Training Corps Students

International Journal of Exercise Science 16(4): 42-52, 2023. The purpose of the present study was to evaluate the relationship between scores achieved in physical fitness tests and outcomes of health and movement screens (HMS) in ROTC students. Twenty-eight students (20 males: 21.8 yrs [± 3.4] & 8 females: 20.7 yrs [± 1.8]) enrolled in an ROTC branch (Army, Air Force, Navy, or Marines) completed a series of screens, including body composition analysis via Dual-Energy X-Ray Absorptiometry (DXA), balance and functional movement tasks via a lower-quarter Y-Balance test, and knee and hip joint concentric strength testing on an isokinetic dynamometer. Official ROTC PFT scores were collected from the respective military branch leadership. HMS outcomes were compared to PFT scores via Pearson Product-Moment Correlation and linear regression analyses. Across branches, total PFT scores were significantly correlated to visceral adipose tissue (r = -0.52, p = 0.01) and android:gynoid fat ratio (r = -0.43, p = 0.04). Visceral adipose tissue (R2 = 0.27, p = 0.011) and android to gynoid ratio (R2 = 0.18, p = 0.042) significantly predicted total PFT scores. No further significant correlations between HMS and overall PFT scores were observed. HMS scores revealed significant bilateral differences in lower extremity body composition (p \u3c 0.001; d = 0.23) and strength (p = 0.002; d = 0.23). Across ROTC branches, HMS were poorly correlated with PFT performance yet indicated significant bilateral differences in lower extremity strength and body composition. The inclusion of HMS may ease the increasing injury rate among the military population by assisting in detection of movement shortcomings

Tobacco and cannabis use in college students are predicted by sex‐dimorphic interactions between MAOA genotype and child abuse

Background Postsecondary students in Western countries exhibit a high prevalence of cannabis and tobacco use disorders. The etiology of these problems is contributed by several psychosocial factors, including childhood adversity and trauma; however, the mechanisms whereby these environmental determinants predispose to the use of these substances remain elusive, due to our poor knowledge of genetic and biological moderators. Converging evidence points to the monoamine oxidase A (MAOA) gene as a moderator of the effects of lifetime stress on the initiation of substance use. Aims Building on these premises, in this study, we analyzed whether MAOA upstream variable number tandem repeat (uVNTR) alleles interact with child maltreatment history to predict for lifetime cannabis and tobacco consumption. Materials and methods Five hundred college students (age: 18–25 years) from a large Midwestern University were surveyed for their child maltreatment history (encompassing emotional, physical, and sexual abuse, as well as emotional and physical neglect) and lifetime consumption of cannabis and tobacco. Saliva samples were obtained to determine the MAOA uVNTR genotype of each participant. Results In female students, lifetime tobacco and cannabis use was predicted by the interaction of physical and emotional abuse with high‐activity MAOA allelic variants; conversely, in males, the interaction of low‐activity MAOA alleles and physical abuse was associated with lifetime use of tobacco, but not cannabis. Discussion These findings collectively suggest that the vulnerability to smoke tobacco and cannabis is predicted by sex‐dimorphic interactions of MAOA gene with childhood abuse. Conclusion These biosocial underpinnings of tobacco and cannabis use may prove important in the development of novel personalized preventive strategies for substance use disorders in adolescents
