Work stress and risk of cancer:meta-analysis of 5700 incident cancer events in 116 000 European men and women

To investigate whether work related stress, measured and defined as job strain, is associated with the overall risk of cancer and the risk of colorectal, lung, breast, or prostate cancers.

Adolescent men’s pregnancy resolution choices in relation to an unintended pregnancy: A comparative analysis of adolescent men in three countries.

This paper investigates adolescent men's pregnancy resolution choices in Australia, Ireland and Italy. It addresses two main gaps in the literature: the lack of research on (adolescent) men's views on unintended pregnancy and pregnancy resolution; and the lack of international comparative case studies on men and reproductive choices. Consistent with theories of the transformation of intimacies in society and the growth of individualization, the results suggest that adolescent men are interested in the effect of an unintended pregnancy on their individual biographies as well as the effect on their girlfriend's health and well-being. However, Australian male adolescents were much more likely to choose abortion than Italian or Irish adolescents, suggesting adolescent males have also internalized country level debates surrounding abortion. Methodologically, the paper demonstrates an innovative approach to data-collection using a computer-based interactive drama to facilitate participants' deliberation and responses. It was shown to engage a large number of adolescent men and is likely to have wider generalisability in developing international comparative research on the topic, as well as applications for health promotion.

Job Strain as a Risk Factor for Leisure-Time Physical Inactivity: An Individual-Participant Meta-Analysis of Up to 170,000 Men and Women

Unfavorable work characteristics, such as low job control and too high or too low job demands, have been suggested to increase the likelihood of physical inactivity during leisure time, but this has not been verified in large-scale studies. The authors combined individual-level data from 14 European cohort studies (baseline years from 19851988 to 20062008) to examine the association between unfavorable work characteristics and leisure-time physical inactivity in a total of 170,162 employees (50 women; mean age, 43.5 years). Of these employees, 56,735 were reexamined after 29 years. In cross-sectional analyses, the odds for physical inactivity were 26 higher (odds ratio 1.26, 95 confidence interval: 1.15, 1.38) for employees with high-strain jobs (low control/high demands) and 21 higher (odds ratio 1.21, 95 confidence interval: 1.11, 1.31) for those with passive jobs (low control/low demands) compared with employees in low-strain jobs (high control/low demands). In prospective analyses restricted to physically active participants, the odds of becoming physically inactive during follow-up were 21 and 20 higher for those with high-strain (odds ratio 1.21, 95 confidence interval: 1.11, 1.32) and passive (odds ratio 1.20, 95 confidence interval: 1.11, 1.30) jobs at baseline. These data suggest that unfavorable work characteristics may have a spillover effect on leisure-time physical activity.

Role of central dopaminergic pathways in the neural control of growth hormone secretion in normal men:Studies with metoclopramide

The aim of this study was to gain further insight into the role that central dopaminergic pathways play in GH neuroregulation in man. Our experimental hypothesis was based on the possibility that most of the controversies on DA role could be due to the fact that the hypothalamic somatotroph rhythm (HSR) was not taken into account when interpreting the GH responses after pharmacological manipulations on dopaminergic pathways. In 10 normal subjects we monitored the effect of central dopaminergic blockade, achieved with metoclopramide (MCP; 10 mg, i.v. Bolus), on the pattern of spontaneous GH secretion and the GH responses to a GHRH challenge (GRF , 1 µg/kg, i.v. bolus) administered together with MCP or 60 min after this drug was given. The study of HSR was made according to our previous postulate. Our results indicate that MCP administration, either prior to or together with the GHRH bolus, significantly increased GHRH-induced GH release during a refractory HSR phase; but not when the GHRH challenge took place during a spotaneous secretory phase. The strong relationship between pre-GHRH plasma GH values and GHRH-elicited GH peaks was lost when MCP was given. These data indicate that MCP was able to disrupt the intrinsic HSR by inhibiting the hypothalamic release of somatostain (SS). While a main conclusion would be that central DA is a secretagogue for SS secretion, our results also suggest that this role could be dependent on its effects on the adrenergic inputs to SS neurons.

α-Adrenergic agonism enhances the growth hormone (GH) response to GH-releasing hormone through an inhibition of hypothalamic somatostatin release in normal men

The purpose of this study was to investigate the precise mechanism by which central a-adrenergic pathways modulate GH secretion in humans. In 10 normal subjects we compared the pattern of clonidine-induced GH release to that elicited by GH-releasing hormone (GHRH) given at a time of presumably similar responsiveness of the somatotrope. We also evaluated the effect of stimulation by GHRH (either endogenous, by administration of clonidine, or exogenous) on the GH response to a further exogenous GHRH stimulation. In 2 experiments the administration of clonidine (0.150 mg, orally) at 0 or 60 min was followed by a GHRH [GRF-(1-29); 1 µg/kg, iv] challenge at 180 min. In other experiments subjects received on separate occasions placebo or clonidine at 0 min, followed by GHRH at 60 min and again at 180 min. In a further experiment the administration of clonidine at 0 min was followed by 2 GHRH challenges (60 and 180 min later). The administration of clonidine 60 or 120 min, but not 180 min, before the GHRH bolus significantly (P <0.01) increased the GH responses to this challenge compared to those elicited by GHRH when given after placebo in a period of a similar somatotrope responsiveness. These, in turn, were significantly (P <0.05) higher than those elicited by clonidine alone. The close relationship between pre-GHRH plasma GH values and GHRH-elicited GH peaks, not observed for clonidine, was lost after pretreatment with this drug. These data indicate that clonidine was able to disrupt the intrinsic hypothalamic-somatotroph rhythm, suggesting that a-adrenergic pathways have a major inhibitory effect on somatostatin release. Our data also indicate that GH responses to a GHRH bolus administered 120 min after a prior GHRH challenge are dependent on two parameters: the intrinsic hypothalamic-somatotroph rhythm at the time of the second GHRH bolus, and the magnitude of GH secretion elicited by the previous somatotroph stimulation. In summary, a-adrenergic agonism appears to act primarily in GH control by inhibiting the hypothalamic release of somatostatin, rather than by stimulating GHRH secretion.

A randomized controlled trial of a self-management psychosocial intervention for men with prostate cancer and their partners: a study protocol.

Background
Little is known about interventions to help men and their partners cope with the after effects of prostate cancer treatment. The lack of in-depth descriptions of the intervention content is hindering the identification of which intervention (or component of an intervention) works.

Aim
To describe the development and evaluation of the content of a self-management psychosocial intervention for men with prostate cancer and their partners.

Design
A feasibility randomized controlled trial including structure, process, and outcome analysis.

Methods
This 9-week intervention commences on completion of treatment and consists of three group and two telephone sessions. The intervention focuses on symptom management, sexual dysfunction, uncertainty management, positive thinking and couple communication. Forty-eight couples will be assigned to either the intervention or a control group receiving usual care. Participants will be assessed at baseline, immediately postintervention and at 1 and 6 months postintervention. Outcome measures for patients and caregivers include self-efficacy, quality of life, symptom distress, uncertainty, benefits of illness, health behaviour, and measures of couple communication and support. An additional caregiver assessment will be completed by the partner.

Discussion
The main purpose of this feasibility study is to investigate the acceptability of the CONNECT programme to men with prostate cancer and their partners and to gain feedback from the participants and facilitators to make changes to and enhance the programme. Reasons why men do not want to participate will be collated to enhance recruitment in the future. We will also test recruitment strategies, randomization procedures, and the acceptability of the questionnaires. Ethical approval granted December 2010.

Where are all the men? The marginalization of men in social scientific research on infertility

There is a wealth of research exploring the psychological consequences of infertility and assisted reproduction technology: a substantial body of sociological and anthropological work on ‘reproductive disruptions’ of many kinds and a small but growing literature on patient perspectives of the quality of care in assisted reproduction. In all these fields, research studies are far more likely to be focused on the understandings and experiences of women than those of men. This paper discusses reasons for the relative exclusion of men in what has been called the ‘psycho-social’ literature on infertility, comments on research on men from psychological and social perspectives and recent work on the quality of patient care, and makes suggestions for a reframing of the research agenda on men and assisted reproduction. Further research is needed in all areas, including: perceptions of infertility and infertility treatment seeking; experiences of treatment; information and support needs; decisions to end treatment; fatherhood post assisted conception; and the motivation and experiences of sperm donors and men who seek fatherhood through surrogacy or co-parenting. This paper argues for multimethod, interdisciplinary research that includes broader populations of men which can contribute to improved clinical practice and support for users of assisted reproduction treatment

Gay men and intimate partner violence: a gender analysis

Though intimate partner violence (IPV) is predominately understood as a women’s health issue most often emerging within heterosexual relationships, there is increasing recognition of the existence of male victims of IPV. In this qualitative study we explored connections between masculinities and IPV among gay men. The findings show how recognising IPV was based on an array of participant experiences, including the emotional, physical and sexual abuse inflicted by their partner, which in turn led to three processes. Normalising and concealing violence referred to the participants’ complicity in accepting violence as part of their relationship and their reluctance to disclose that they were victims of IPV. Realising a way out included the participants’ understandings that the triggers for, and patterns of, IPV would best be quelled by leaving the relationship. Nurturing recovery detailed the strategies employed by participants to mend and sustain their wellbeing in the aftermath of leaving an abusive relationship. In terms of masculinities and men’s health research, the findings reveal the limits of idealising hegemonic masculinities and gender relations as heterosexual, while highlighting a plurality of gay masculinities and the need for IPV support services that bridge the divide between male and female as well as between homosexual and heterosexual.

Blueberries decrease cardiovascular risk factors in obese men and women with metabolic syndrome

Among all fruits, berries have shown substantial cardio-protective benefits due to their high polyphenol content. However, investigation of their efficacy in improving features of metabolic syndrome and related cardiovascular risk factors in obesity is limited. We examined the effects of blueberry supplementation on features of metabolic syndrome, lipid peroxidation, and inflammation in obese men and women. Forty-eight participants with metabolic syndrome [4 males and 44 females; BMI: 37.8 +/- 2.3 kg/m(2); age: 50.0 +/- 3.0 y (mean +/- SE)] consumed freeze-dried blueberry beverage (50 g freeze-dried blueberries, approximately 350 g fresh blueberries) or equivalent amounts of fluids (controls, 960 mL water) daily for 8 wk in a randomized controlled trial. Anthropometric and blood pressure measurements, assessment of dietary intakes, and fasting blood draws were conducted at screening and at wk 4 and 8 of the study. The decreases in systolic and diastolic blood pressures were greater in the blueberry-supplemented group (- 6 and - 4%, respectively) than in controls (- 1.5 and - 1.2%) (P lt 0.05), whereas the serum glucose concentration and lipid profiles were not affected. The decreases in plasma oxidized LDL and serum malondialdehyde and hydroxynonenal concentrations were greater in the blueberry group (- 28 and - 17%, respectively) than in the control group (- 9 and - 9%) (P lt 0.01). Our study shows blueberries may improve selected features of metabolic syndrome and related cardiovascular risk factors at dietary achievable doses.

You’re Wha…? Including young men in reproductive planning

The importance of including fathers in reproductive planning, pregnancy and childbirth cannot be overstated and it is increasingly recognised that addressing their sense of exclusion from maternity services requires further action. One very overlooked area, however, is in helping young men, alongside their partners, in preventing an unintended teenage pregnancy. The UK has the highest rate of teenage pregnancy in Western Europe and, while teenage men are seen as half of the problem, they are rarely regarded as half of the solution. We argue that education is an essential part of the process of increasing men's sense of inclusion and describe If I were Jack, an educational resource about unintended teenage pregnancy which has been developed specifically for young men.

Peer injecting: implications for injecting order and blood-borne viruses among men and women who inject heroin

A large body of research has highlighted practices and rituals that characterise injecting drug use and behavioural and environmental risks that can contribute to the transmission of blood-borne viruses. Compared with other injecting practices, considerably less is known about peer injecting, i.e. receiving or giving injections, particularly the social context in which it occurs. In this article, we explore peer injecting and injecting order at initiation into injecting drug user (IDU) and during subsequent injection episodes. Using data from semi-structured interviews, we highlight the experiences of 41 males and females who had received injections from other IDUs. Respondents were recruited through various strategies, largely chain referral. The results suggest gendered similarities as well as differences in terms of peer injecting, the order of injection and micro-risk contexts for blood-borne viruses. © 2013 Informa UK Ltd.

Pioglitazone protects HDL(2&3) against oxidation in overweight and obese men

The worldwide epidemic of obesity is a major public health concern and is persuasively linked to the rising prevalence of diabetes and cardiovascular disease. Obesity is often associated with an abnormal lipoprotein profile, which may be partly negated by pioglitazone intervention, as this can influence the composition and oxidation characteristics of low-density lipoprotein (LDL). However, as pioglitazone's impact on these parameters within high-density lipoprotein (HDL), specifically HDL(2&3), is absent from the literature, this study was performed to address this shortcoming.
