Could seasonal variation in testosterone levels in men be related to sleep?

We have previously reported seasonal variations in both total and free testosterone in men living in north Norway. The aim of this cross-sectional study was to determine whether seasonal variation in testosterone also occurs in men living in geographical areas with less extreme seasonal variation in sunlight and temperature. In 915 men aged 24–91 years from Rancho Bernardo, a suburb of San Diego in southern California, we found that neither total nor bioavailable testosterone varied by season, with or without adjustments for age and anthropometric measurements. Of all examined covariates, only physical activity showed a seasonal variation, with a peak in August (p <?0.001), and adjusting for physical activity did not change the lack of seasonal variation in testosterone. In addition, there was no association between testosterone and mean air temperature, or testosterone and possible hours of sunshine. We conclude that men living in southern California show no seasonal variation in testosterone levels. One possible explanation, besides the difference in climate, for the diverging findings between our previous study and the present study is different sleep patterns.     

The influence of exercise on the functioning of the pituitary–gonadal axis in physically active older and younger men

Age is a meaningful factor modulating the functioning of the human endocrine system. In our research, the factor stimulating the pituitary–gonadal axis was a 400 m race. In this type of effort, glycolytic and lactic acid transformations are dominant and a fundamental increase in lactic acid concentration is noted. The aim of the research was to compare the response of the pituitary–gonadal axis in physically active men of various ages after a 400 m race. Nine men aged 21.7 ± 0.7 years and nine men aged 60.0 ± 3.4 years took part in the study. Blood samples were taken from the elbow vein before the race at 08.00 and immediately after the effort. The levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), total testosterone and free testosterone were determined in blood sera. The concentration of lactic acid was measured in full blood at 5 min after the race. Before the effort, statistically significant differences in the concentration of FSH and free testosterone between the two age groups were observed (higher FSH in older men but lower free testosterone). No differences in the level of LH, total testosterone and lactic acid were observed. Immediately after the effort, no changes in the level of FSH were found in both groups; a statistically significant decrease in LH concentration was noted only in the group of younger men. In both groups, statistically significant increases in total testosterone, free testosterone and lactic acid concentrations were observed after the race. In the group of younger men, compared to the older, larger increases in free testosterone and lactic acid concentrations, as well as shorter race time, were revealed after the effort test. Analysis of the two groups after the race showed statistically significant differences in FSH, free testosterone and lactic acid concentrations. A positive correlation (r = 0.57) was demonstrated between the after-effort increase in the concentration of free testosterone and lactic acid, and negative correlation (r = –0.66) between the after-effort increase in the concentration of free testosterone and the time of the 400 m race. In older men, the concentration of free testosterone may play an important function in lowering strength capacities. It must be stressed that the 400 m race was a more significant stimulus for changes in hormone concentrations of the pituitary–gonadal axis in younger men (greater changes in the level of the investigated parameters) than in the older. The results obtained allow us to conclude that, in older men, as compared to the younger ones, the response of the pituitary–gonadal axis to an effort stimulus is to some extent different.     

Effects of heart rate reduction with ivabradine on the international ındex of erectile function (IIEF-5) in patients with heart failure

Introduction: The presence of concomitant erectile dysfunction (ED) with heart failure (HF) is not surprising, because endothelial dysfunction is pathophysiologic signature of both ED and HF. ED significantly and adversely affects quality of life in patients with HF. It was demonstrated that ivabradine treatment can improve endothelial function and ED in experimental models. In this study, we aimed to determine the effect of ivabradine treatment on ED in patients with HF via International Index of Erectile Function (IIEF-5) questionaire.

Material and methods: Consequently, 29 patients, between 18 and 70?years of age, male with chronic HF known for at least 1?year, New York Heart Association functional class I–II, left ventricule ejection fraction less than 40%, in sinus rhythm with a resting HR of at least 70 beats per minute (b.p.m.), who were intended to be treated with ivabradine according to the decision of their physicians were evaluated to determine ED. We used the Turkish version of the IIEF-5 questionnaire to evaluate ED on the last 6-month period. Twenty-four of 29 patients who scored ≤21 were considered to have ED and included to the study. IIEF-5 scores for each question and domains were calculated for all responders at baseline and at 6-month follow-up visit in order to determine any effect of ivabradine treatment on ED in patients with HF.

Results: According to the data of survey, Cronbach's alpha coeffient for all of the patients who were included into the study were 0.84 and detected highly reliable. IEFF-5 questionnaire scores increased significantly (p?=?.003) after the ivabradine treatment, on the contrary, significant decrease in HR was revealed as expected. HR is decreased steadily after ivabradine treatment and mean decrease in HR was 11.5?±?9.4 in this study population. Likewise, negative correlation was demonstrated between decrease in HR (p?p?=?.003).

Conclusion: Although lack of patients with HF have been evaluated in this study population, initial results seem promising that ivabradine has favorable effects on ED. These findings were postulated to be dependent exclusively on HR reduction. As a sequel, cardiologist should avoid neglecting ED to improve medical compliance as well as quality of life in patients with heart failure. This pilot study provide some data for further randomized controlled studies.     

Economic incentives and the epidemiological indicators can contribute to the reduction of occupational hazards?

This article intends to discuss the interfaces of Decree No. 6042 and the adoption of its guidelines as a strategy to reduce the occupational hazards.     

How do Spanish disability support offices contribute to inclusive education in the university?

This article analyzes the functioning of disability support offices and their contribution to inclusive education in seven Spanish universities from the perspective of staff. Using a qualitative methodology, interviews with office staff were conducted, and data were analyzed through an inductive coding system. The results are organized around five themes: characteristics of disability support offices, staff training, functions performed by different services, barriers and opportunities identified by office staff, and proposals to improve attention given to disabled students. Information gathered leads to the conclusion that the work carried out in disability support offices must receive support from universities, as these offices are a key element for the access and retention of students with disabilities in the university and for the successful completion of their studies.     

Working with the enemy? Social work education and men who use intimate partner violence

This article examines service user involvement in social work education. It discusses the challenges and ethical considerations of involving populations who may previously have been excluded from user involvement initiatives, raising questions about the benefits and challenges of their involvement. The article then provides discussion of an approach to service user involvement in social work education with one of these populations, men who use violence in their intimate relationships, and concludes by considering the implications of their involvement for the social work academy.     

How can stigma contribute to our understanding of the formation and mobilization of collective identities in health social movements?

Scholars across several theoretical traditions have become increasingly interested in understanding the underlying factors and mechanisms that contribute to the formation and mobilization of collective identities in health social movements (HSMs). In this essay, I make the case that stigma can serve as a useful theoretical and conceptual framework in understanding the processes through which collective identities emerge and mobilize around health‐related issues. I begin by introducing the concepts of HSMs, collective identity and stigma and reviewing how scholars have defined these concepts. Next, I establish theoretical, conceptual, and empirical links among stigma, collective identity, and HSMs. I conclude by further specifying how and why stigma can serve as a unifying framework for medical sociologists, social psychologists, and social movement researchers to advance scholarship on HSMs.     

How does functional disability affect depressive symptoms in late life? The role of perceived social support and psychological resources

This study examines the process whereby functional disability amplifies depressive symptoms through decreasing perceived social support and psychological resources. The study analyzed two waves of panel data (1986 to 1992) of a large sample of older adults from the National Institutes of Aging Established Populations for Epidemiologic Studies of the Elderly. The results of longitudinal change models and path analyses show that the perceived availability of a confidant, satisfaction with support, sense of control, and self-esteem mediate the effects of disability on increments in depressive symptoms in late life. Psychological resources play a dominant role in mediating the effects of functional impairment. Scales of sense of control and self-esteem account for 53 percent of the total effect of baseline disability and 43 percent of the total effect of changes in disability on changes in the CES-D depression scale. Self-esteem appears to be the strongest mediator.     

Does subliminal exposure to sexual stimuli have the same effects on men and women?

Three studies explored gender differences in explicit and implicit components of sexual arousal following brief exposure to a sexual stimulus. Whereas Study 1 assessed reports of sexual arousal following subliminal exposure to a sexual or a neutral picture, Studies 2 and 3 examined the effects of the same priming procedure on accessibility of sex-related thoughts assessed with a pictorial judgment task and a lexical decision task. The subliminal sexual prime did not have an effect on men's reports of sexual arousal, but caused women to report lower levels of sexual arousal. In contrast, the same subliminal sexual prime led to higher accessibility of sex-related thoughts in both men and women. It is therefore suggested that the subliminal sexual prime causes women to activate sex-related mental contents but to experience the result as somewhat aversive.     

Advice given to women undergoing gynaecological surgery in relation to menopause, symptoms and hormone replacement therapy: could and should we improve the service we provide?

Can weight predict academic performance in college students? An analysis of college women's self-efficacy,absenteeism, and depressive symptoms as mediators

Over a third of American college students are either overweight or obese, which has been suggested to negatively impact their academic achievement. Objective: This study seeks to better understand the relationship between body mass index (BMI) and grade point average (GPA), while examining potential mediators of this association. Participants and Methods: The sample consists of 298 college women who volunteered to complete online questionnaires between October and December 2014. Results: Although no significant differences were noted for sociodemographic variables, overweight and obese female students were found to report lower GPA and academic self-efficacy as well as higher depressive symptoms, compared with their normal-weight counterparts. Academic self-efficacy partially mediated the relationship between BMI and GPA. Conclusions: To foster better academic achievement in female college students, and especially for those who are overweight and obese, strategies for improving self-efficacy and adaptation to college should be implemented.     

Interagency practice in children with non‐organic failure to thrive: is there a gap between health and social care?

Failure to thrive is a child protection issue that crosses the boundaries between many professional groups. It is a condition that places children at risk of negative developmental, social, physical and emotional consequences, but it has complex causal roots. Although there are known to be links between neglect, emotional abuse and failure to thrive, health and social care providers have differing responses and interventions with children who are failing to thrive. An examination of recent Scottish statistics supports the argument that there may be a gap between health and social care that some children may be falling through. Evidence from the literature regarding interagency roles and responsibilities is ambiguous, and the different, albeit overlapping, professional constructions of failure to thrive may result in a gap in care for some vulnerable children. It is only by beginning to understand the crucial links between different professions that we can contribute towards effective interagency child protection policy and practice.

How many men work in the English early years sector? Why is the low figure so ‘stubbornly resistant to change’?

This study draws on data from the GenderEYE project, research conducted in England between 2018 and 2020, which aimed to examine the recruitment, support and retention of male teachers within early years education (EYE) with a view of developing a more gender diverse workforce in this sector. Data collection was by means of a survey, 9 case studies with early years settings and interviews with key stakeholders. In this study, we examine a key finding about the persistently low numbers of male EYE professionals, linking this to another finding concerning a lack of specific strategy to recruit and support men.     

Is it Possible to Develop and Sustain Non-Traditional Placements? An Evaluation of the Development of Practice Learning Opportunities in Partnership with the Police and Probation Services in the West Midlands

This paper will look at new practice learning opportunities developed between the University of Birmingham and the West Midlands Police and Probation Services. The project was designed to expand placements in the West Midlands, to address in particular the short fall of final year placements and to offer students interested in the area of criminal justice and protection of vulnerable people the chance to have a different type of practice experience.

This paper aims to share the learning gained through an evaluation of the first year of this partnership (2009–2010). The paper will provide an overview of the scheme, outline the process of evaluation and will consider the learning gained from the police and probation schemes separately. The paper will draw on feedback gained through discussions in focus groups and questionnaires completed by work base supervisors, specialist social work practice assessors, practice tutors and students in each setting. The strengths and weaknesses of both schemes will be considered as will lessons for improving and building on the project for future years. The paper will also address questions about the relevance of working with non-traditional agencies particularly in light of the new statutory definition relating to final year social work placements.     

“Why are you trying to destroy the last good thing men have?” Understanding resistance to women in combat jobs

This article argues that opposition to expansion of women's roles in the US military and peer armed forces, particularly into combat-related military occupational specialties, is based on defending a means of proving masculinity and preserving access to power. Research is based on policies of US, UK, and other NATO countries, public statements made by officials, academic articles, and interviews with current and former members of the US military. The article examines shifting definitions of combat, historical examples of American women’s military service, and common and persistent themes of resistance to women in combat roles. The article argues that resistance to women in combat roles is not only inconsistent with operational realities, but is both counterproductive to mission effectiveness, and may even put lives at risk. The article concludes that in an ever-shifting security environment requiring critical thinking, cross-cultural communication, and civil–military collaboration, rethinking gender roles may be advantageous.     

Are our Frontline Clinicians Equipped with the Ability and Confidence to Address Child Abuse and Neglect?

Previous studies have suggested that child abuse and neglect (CAN) is under recognised and under reported. Our aims were to examine and compare child protection (CP) knowledge, confidence and practice of frontline clinicians in general practice and hospital settings in South Western Sydney (SWS). We surveyed doctors and nurses in general practice and in the emergency department (ED) in a district in SWS using a validated questionnaire. Of the 113 responses, 62 were general practitioners (GPs), 9 practice nurses, 26 ED nurses and 16 ED doctors. The confidence level with identifying CAN was moderate, with a significant difference between groups. The majority (59%) had made previous CP reports, few suspected but decided not to report; reporting rates differed significantly. A majority (80%) reported some CP training; of the 22 with no training, 21 were GPs and practice nurses. Of those reporting some training, more than 70 per cent of ED nurses, GPs and practice nurses felt their training was inadequate, compared with 19 per cent of ED doctors. There are significant differences in confidence and practice between frontline clinicians in primary care and ED. Targeted CP training should be provided for all frontline clinicians with particular emphasis on primary care GPs. Copyright © 2011 John Wiley & Sons, Ltd.
