How do young men want to receive information about fertility? Young men's attitudes towards a fertility campaign targeting men in Copenhagen, Denmark.

STUDY QUESTION: What are young men's attitudes towards the Danish fertility campaign 'How's your sperm?' and how do they want to receive fertility information in the future? SUMMARY ANSWER: The young men found that the campaign had limited impact because it was not relevant to their current life situation and they believed general fertility awareness should be a mandatory part of education, while more targeted information would be helpful through web-based venues when it was more relevant to their lives (e.g. when ready to have children). WHAT IS KNOWN ALREADY: It is estimated that 16-26% of the Danish population who want children will experience infertility at some point in their lives. In Denmark, 25% of young healthy men have decreased sperm quality, and 20% of 50-year-old men are childless. Men play an important role in the fertility decision-making of couples, thus, it is important to target men and ensure that they have sufficient fertility knowledge. However, fertility awareness is limited among men and there have been few fertility awareness initiatives targeting men. In October 2018, the Municipality of Copenhagen launched the campaign 'How's your sperm?' as a tool to increase fertility knowledge among men. To identify potential barriers for the effect of fertility campaigns targeting men, evaluations of such campaigns are needed. STUDY DESIGN SIZE DURATION: This study was a cross-sectional, qualitative study of six focus groups including a total of 27 currently childless young men from the Capital Region of Copenhagen, Denmark. Data collection took place between April and October 2019. PARTICIPANTS/MATERIALS SETTING METHODS: The interviewed young men were currently childless and were all residents in the Capital Region of Copenhagen. They were between 23 and 32 years old with an average age of 26 years, and almost all were university students or had a university degree. The focus group discussions were audiotaped, anonymized and transcribed in full. Data were analyzed using qualitative content analysis. MAIN RESULTS AND THE ROLE OF CHANCE: Overall, the campaign had limited influence on the young men because they believed the campaign was not relevant to their current life situation. Furthermore, the young men were confused about the aim and message of the campaign, as they thought it encouraged them to have their sperm quality tested. The young men also criticized the campaign for making a link between sperm quality and masculinity. They recognized the importance of knowledge about reproductive health but they wanted access to accurate information about fertility and risk factors for infertility. According to the young men, future initiatives should prioritize clear communication of accurate, reliable and understandable fertility information in web-based venues. In addition, the young men suggested that general fertility information should be a mandatory part of the (sexual) education curriculum in primary and secondary schools. LIMITATIONS REASONS FOR CAUTIONS: Participants were young and highly educated; thus the findings cannot be generalized to all men of a similar age group or to men at older ages. WIDER IMPLICATIONS OF THE FINDINGS: Different strategies that are relevant to the lifespan are needed to increase fertility awareness in the male population. The young men's responses underscored that any fertility awareness strategy or campaign must convey respect for the individual's autonomy. The findings highlight that how information is communicated and the quality or type of information that is disseminated are both important in acceptability by target users.

SEIS: Insight's Seismic Experiment for Internal Structure of Mars.

By the end of 2018, 42 years after the landing of the two Viking seismometers on Mars, InSight will deploy onto Mars' surface the SEIS (Seismic Experiment for Internal Structure) instrument; a six-axes seismometer equipped with both a long-period three-axes Very Broad Band (VBB) instrument and a three-axes short-period (SP) instrument. These six sensors will cover a broad range of the seismic bandwidth, from 0.01 Hz to 50 Hz, with possible extension to longer periods. Data will be transmitted in the form of three continuous VBB components at 2 sample per second (sps), an estimation of the short period energy content from the SP at 1 sps and a continuous compound VBB/SP vertical axis at 10 sps. The continuous streams will be augmented by requested event data with sample rates from 20 to 100 sps. SEIS will improve upon the existing resolution of Viking's Mars seismic monitoring by a factor of ∼ 2500 at 1 Hz and ∼ 200 000 at 0.1 Hz. An additional major improvement is that, contrary to Viking, the seismometers will be deployed via a robotic arm directly onto Mars' surface and will be protected against temperature and wind by highly efficient thermal and wind shielding. Based on existing knowledge of Mars, it is reasonable to infer a moment magnitude detection threshold of M w ∼ 3 at 40 ∘ epicentral distance and a potential to detect several tens of quakes and about five impacts per year. In this paper, we first describe the science goals of the experiment and the rationale used to define its requirements. We then provide a detailed description of the hardware, from the sensors to the deployment system and associated performance, including transfer functions of the seismic sensors and temperature sensors. We conclude by describing the experiment ground segment, including data processing services, outreach and education networks and provide a description of the format to be used for future data distribution.

Self-rated health as a predictor of outcomes of type 2 diabetes patient education programmes in Denmark.

OBJECTIVE: To explore if self-rated health (SRH) can predict differences in outcomes of patient education programmes among patients with type 2 diabetes over time. STUDY DESIGN: This is an observational cohort study conducted among 83 patients with type 2 diabetes participating in patient education programmes in the Capital Region of Denmark. METHODS: Questionnaire data were collected by telephone interview at baseline and 2 weeks (77 participants, 93%) and 12 months (66, 80%) after the patient education ended. The seven-scale Health Education Impact Questionnaire (HeiQ) was the primary outcome. The independent variable was SRH, which was dichotomized into optimal or poor SRH. Changes over time were assessed using mean values and standard deviation (SD) at each time point and Cohen effect sizes. Odds ratios and 95% confidence intervals were calculated for the likelihood of having poor SRH for each baseline sociodemographic and health-related variable. RESULTS: Twelve months after patient education programmes, 60 (72%) patients with optimal SRH at baseline demonstrated increased self-management skills, overall acceptance of chronic illness, positive social interaction with others, and improved emotional well-being. Participants with poor SRH (23, 28%) reported no improvements over time. Not being married (odds ratio [OR] 7.79, P < 0.001), living alone (OR 4.93, P = 0.003), having hypertension (OR 8.00, P = 0.031), and being severely obese (OR 4.07, P = 0.009) were significantly associated with having poor SRH. After adjusting for sex, age and vocational training, marital status (OR 9.35, P < 0.001), cohabitation status (OR = 4.96, P = 0.005) and hypertension (OR 10.9, P = 0.03) remained associated with poor SRH. CONCLUSIONS: We found a strong association between SRH and outcomes of patient education, as measured by the HeiQ, at 12 months. Only participants with optimal SRH appeared to benefit from patient education. Other patient characteristics may be responsible to explain the observed difference between patients with optimal and poor SRH.

Sublimation in bright spots on (1) Ceres.

The dwarf planet (1) Ceres, the largest object in the main asteroid belt with a mean diameter of about 950 kilometres, is located at a mean distance from the Sun of about 2.8 astronomical units (one astronomical unit is the Earth-Sun distance). Thermal evolution models suggest that it is a differentiated body with potential geological activity. Unlike on the icy satellites of Jupiter and Saturn, where tidal forces are responsible for spewing briny water into space, no tidal forces are acting on Ceres. In the absence of such forces, most objects in the main asteroid belt are expected to be geologically inert. The recent discovery of water vapour absorption near Ceres and previous detection of bound water and OH near and on Ceres (refs 5-7) have raised interest in the possible presence of surface ice. Here we report the presence of localized bright areas on Ceres from an orbiting imager. These unusual areas are consistent with hydrated magnesium sulfates mixed with dark background material, although other compositions are possible. Of particular interest is a bright pit on the floor of crater Occator that exhibits probable sublimation of water ice, producing haze clouds inside the crater that appear and disappear with a diurnal rhythm. Slow-moving condensed-ice or dust particles may explain this haze. We conclude that Ceres must have accreted material from beyond the 'snow line', which is the distance from the Sun at which water molecules condense.

Association of physical workload and leisure time physical activity with incident mobility limitations: a follow-up study.

OBJECTIVES: To examine individual as well as joint associations of physical workload and leisure time physical activity with incident mobility limitations in initially well-functioning middle-aged workers. METHODS: This study is based on 6-year follow-up data of the Danish Longitudinal Study on Work, Unemployment and Health. Physical workload was reported at baseline and categorised as light, moderate or heavy. Baseline leisure time physical activity level was categorised as sedentary or active following the current recommendations on physical activity. Incidence of mobility limitations in climbing stairs and running among initially well-functioning workers (n=3202 and n=2821, respectively) was assessed during follow-up. RESULTS: Higher workload increased whereas active leisure time decreased the risk of developing mobility limitations. The incidence of limitations increased progressively with higher workload regardless of level of leisure time physical activity, although the risks tended to be higher among those with sedentary leisure time compared with their active counterparts. All in all, the risk for onset of mobility limitations was highest among those with heavy workload combined with sedentary leisure time and lowest among those with light workload combined with active leisure time. CONCLUSIONS: Although leisure time physical activity prevents development of mobility decline, high workload seems to accelerate the progression of mobility limitations among both those with active and sedentary leisure time. Therefore, efforts should be made to recommend people to engage in physical activity regardless of their physical workload.

Dawn at Vesta: testing the protoplanetary paradigm.

The Dawn spacecraft targeted 4 Vesta, believed to be a remnant intact protoplanet from the earliest epoch of solar system formation, based on analyses of howardite-eucrite-diogenite (HED) meteorites that indicate a differentiated parent body. Dawn observations reveal a giant basin at Vesta's south pole, whose excavation was sufficient to produce Vesta-family asteroids (Vestoids) and HED meteorites. The spatially resolved mineralogy of the surface reflects the composition of the HED meteorites, confirming the formation of Vesta's crust by melting of a chondritic parent body. Vesta's mass, volume, and gravitational field are consistent with a core having an average radius of 107 to 113 kilometers, indicating sufficient internal melting to segregate iron. Dawn's results confirm predictions that Vesta differentiated and support its identification as the parent body of the HEDs.

Reduced probability of smoking cessation in men with increasing number of job losses and partnership breakdowns.

BACKGROUND: Unemployment and partnership breakdowns are common stressful life events, but their association with smoking cessation has been investigated in only a few studies. OBJECTIVE: To investigate how history of employment and cohabitation affects the probability of smoking cessation and to study joint exposure to both. METHODS: Birth cohort study of smoking cessation of 6232 Danish men born in 1953 with a follow-up at age 51 (response rate 66.2%). History of unemployment and cohabitation was measured annually using register data. Information on smoking cessation was obtained by a questionnaire. RESULTS: The probability of smoking cessation decreased with the number of job losses (ranging from 1 OR 0.54 (95% CI 0.46 to 0.64) to 3+ OR 0.41 (95% CI 0.30 to 0.55)) and of broken partnerships (ranging from 1 OR 0.74 (95% CI 0.63 to 0.85) to 3+ OR 0.50 (95% CI 0.39 to 0.63)). Furthermore, smoking cessation was associated with the duration of the periods of unemployment (ranging from 1-5 years (OR 0.75, 95% CI 0.65 to 0.85) to 10-23 years (OR 0.29, 95% CI 0.22 to 0.38)) and with living without a partner for > 5 years (ranging from 6-9 years to 10-23 years (OR 0.80, 95% CI 0.66 to 0.97) to 10-23 years (OR 0.44, 95% CI 0.37 to 0.52)). Those who never cohabited and experienced one or more job losses had a particular low chance of smoking cessation (OR 0.19, 95% CI 0.12 to 0.30). CONCLUSION: The numbers of job losses and of broken partnerships were both inversely associated with probability of smoking cessation.

Macular morphology and visual acuity after macular hole surgery with or without internal limiting membrane peeling.

AIM: To examine postoperative macular morphology and visual outcome after 12 months in relation to internal limiting membrane (ILM) peeling versus no peeling, indocyanine green (ICG) staining and re-operation in eyes that achieved macular hole closure after surgery. METHODS: Seventy-four eyes with closed stage 2 or 3 macular holes were recruited from a randomised clinical trial comparing: (1) vitrectomy without ILM peeling; (2) vitrectomy with 0.05% isotonic ICG-assisted ILM peeling; and (3) vitrectomy with 0.15% trypan blue-assisted ILM peeling. Contrast-enhanced Stratus optical coherence tomography was used to assess central foveal thickness, central photoreceptor layer thickness (CPRT), central photoreceptor layer discontinuity (PRD) and relative reflectivity of the outer nuclear layer. Outcomes were correlated with best corrected visual acuity (BCVA) 12 months after surgery. RESULTS: BCVA was correlated with CPRT and PRD. Regression analysis and receiver operating characteristics curve analysis showed that CPRT >33 microm (OR 12.5) and PRD <177 microm (OR 9.86) were highly predictive for regaining reading vision (> or =69 Early Treatment of Diabetic Retinopathy Study letters) 12 months after surgery. No significant difference was found in postoperative macular morphology between subgroups. CONCLUSIONS: Poor vision after 12 months despite macular hole closure was associated with attenuation and disruption of the foveolar photoreceptor matrix. The extent of attenuation and disruption was independent of peeling and staining. TRIAL REGISTRATION NUMBER: NCT00302328.

Effects of aging on human skeletal muscle after immobilization and retraining.

Inactivity is a recognized compounding factor in sarcopenia and muscle weakness in old age. However, while the negative effects of unloading on skeletal muscle in young individuals are well elucidated, only little is known about the consequence of immobilization and the regenerative capacity in elderly individuals. Thus the aim of this study was to examine the effect of aging on changes in muscle contractile properties, specific force, and muscle mass characteristics in 9 old (61-74 yr) and 11 young men (21-27 yr) after 2 wk of immobilization and 4 wk of retraining. Both young and old experienced decreases in maximal muscle strength, resting twitch peak torque and twitch rate of force development, quadriceps muscle volume, pennation angle, and specific force after 2 wk of immobilization (P < 0.05). The decline in quadriceps volume and pennation angle was smaller in old compared with young (P < 0.05). In contrast, only old men experienced a decrease in quadriceps activation. After retraining, both young and old regained their initial muscle strength, but old had smaller gains in quadriceps volume compared with young, and pennation angle increased in young only (P < 0.05). The present study is the first to demonstrate that aging alters the neuromuscular response to short-term disuse and recovery in humans. Notably, immobilization had a greater impact on neuronal motor function in old individuals, while young individuals were more affected at the muscle level. In addition, old individuals showed an attenuated response to retraining after immobilization compared with young individuals.

The impact of social relations on the incidence of severe depressive symptoms among infertile women and men.

BACKGROUND: The present study investigates anticipated support and perceived appreciation as well as perceived negative aspects of social relations as determinants of the incidence of severe depressive symptoms among women and men in unsuccessful fertility treatment. METHODS: A prospective cohort study of consecutively recruited, new couples in fertility treatment completed questionnaires immediately before initiating treatment (T1) and at 1-year follow-up (T2) (response rates 80%, 88%). The study population included 695 participants (355 women and 340 men) who had no severe depressive symptoms at T1, who had no child together at T1 and whose treatment had failed. We measured severe depressive symptoms with Mental Health Inventory 5 from Short-Form 36, functional aspects of general social relations and of infertility-specific social relations. RESULTS: Fifteen per cent of women and 6% of men in unsuccessful treatment reported severe depressive symptoms at T2. Among men, low emotional support, low appreciation and high excessive demands from the partner were significant determinants of the incidence of severe depressive symptoms. Among women and men, low appreciation from the family, many conflicts and high excessive demands from family, friends and neighbours were significant determinants of severe depressive symptoms. The analyses were controlled for gender. Duration of infertility, infertility diagnosis and socio-economic position did not confound the associations. CONCLUSIONS: More women than men report severe depressive symptoms after 1 year of unsuccessful treatment. It is important to be aware of the possible negative impact of relational strain among fertility patients in unsuccessful treatment.

The longitudinal impact of partner coping in couples following 5 years of unsuccessful fertility treatments.

BACKGROUND: Because there is a lack of longitudinal research examining the impact of partner coping in couples experiencing infertility, we know very little about the long-term nature of coping with infertility and how partner coping strategies impact personal, marital and social distress. METHODS: Participants were Danish men and women about to start a cycle of assisted reproduction treatment who were followed for a 5 year period of unsuccessful treatments. Multilevel modeling using the actor-partner interdependence model was used to examine the couple as the unit of analysis. RESULTS: Active and passive avoidance coping strategies were significantly related to increased personal, marital and social distress at the individual and partner level. Meaning-based coping strategies were related to decreases in a woman's individual distress and her partner's marital distress. CONCLUSIONS: Partner coping strategies have a significant impact on the other member of the couple over time in men and women undergoing infertility treatments over a 5 year period. Physicians and mental health professionals can educate men and women regarding the ineffectiveness of avoidance coping strategies as well as the beneficial nature of finding new meaning and life goals while experiencing the stress of infertility.

Value of internal limiting membrane peeling in surgery for idiopathic macular hole stage 2 and 3: a randomised clinical trial.

AIM: To determine the effect of internal limiting membrane (ILM) peeling on anatomical and functional success rates in stage 2 and 3 idiopathic macular hole surgery (MHS). METHODS: Randomised clinical trial of stage 2 and 3 idiopathic macular hole without visible epiretinal fibrosis and with less than 1 year's duration of symptoms. Eyes were randomised to (1) vitrectomy alone without retinal surface manipulation, (2) vitrectomy plus 0.05% isotonic Indocyanine Green (ICG)-assisted ILM peeling or (3) vitrectomy plus 0.15% Trypan Blue (TB)-assisted ILM peeling. Main outcomes were hole closure after 3 and 12 months and best-corrected visual acuity after 12 months. RESULTS: 78 eyes were enrolled. Primary closure rates were significantly higher with ILM peeling than without peeling for both stage 2 holes (ICG peeling 100%, non-peeling 55%, p = 0.014) and for stage 3 holes (ICG peeling 91%, TB peeling 89%, non-peeling 36%, p<0.001). Visual outcomes in eyes with primary hole closure were not significantly different between the groups. CONCLUSIONS: Dye-assisted ILM peeling was associated with significantly higher closure rates than non-peeling in both stage 2 and 3 MHS. Intraoperative ILM staining with 0.05% isotonic ICG was not associated with a significantly different visual outcome than non-peeling or TB peeling in eyes with primary hole closure. TRIAL REGISTRATION NUMBER: NCT00302328.

Normative data of outer photoreceptor layer thickness obtained by software image enhancing based on Stratus optical coherence tomography images.

AIM: To present normative data of outer photoreceptor layer thickness obtained by a new semiautomatic image analysis algorithm operating on contrast-enhanced optical coherence tomography (OCT) images. METHODS: Eight Stratus OCT3 scans from identical retinal locations from 25 normal eyes were registered and combined to form a contrast-enhanced average image. Utilising the vertical intensity gradients of the enhanced OCT images to demarcate retinal layers, thickness measurements of the outer photoreceptor- and retinal pigment epithelium layer (RPE-OS(complex)) were obtained. Additionally backscattered light within the outer nuclear layer (ONL) in the fovea was registered and compared with backscattered light within the ONL in the peripheral part of the macula (I(ratio)-ONL). RESULTS: The mean RPE-OS(complex) thickness in the foveal centre was 77.2 microm (SD = 3.95). The RPE-OS(complex) thickness in the superior macula 0.5-3 mm of the centre was significantly increased as compared with the corresponding inferior retina. In healthy subjects, the I(ratio)-ONL was 1.06. CONCLUSIONS: Contrast-enhanced OCT images enable quantification of outer photoreceptor layer thickness, and normative values may help understanding better the relationship between functional outcome and photoreceptor morphology in retinal diseases.

The impact of partner coping in couples experiencing infertility.

BACKGROUND: Most studies examining coping with infertility use the individual as the unit of analysis. Although valuable, these studies fail to show the impact that partner coping has on individual distress. Since infertility is a shared stressor, examining the impact of partner coping is particularly relevant. METHODS: Data were based on a questionnaire in a consecutive sample of 1169 women and 1081 Danish men prior to beginning assisted reproduction treatment. Multilevel modeling using the Actor Partner Interdependence Model and follow-up analysis of variance were used to examine the couple as the unit of analysis. RESULTS: A partner's use of active-avoidance coping was related to the increased personal, marital and social distress for men and women. A woman's use of active-confronting coping was related to increased male marital distress. And a partner's use of meaning-based coping was associated with decreased marital distress in men and increased social distress in women. CONCLUSIONS: Although understudied, partner coping patterns play a key role in a partner's ability to cope with the infertility experience. Physicians and mental health providers can help couples to understand the coping strategies that lead to increased and decreased partner distress.

Functional ability at age 75: is there an impact of physical inactivity from middle age to early old age?

The aim of this study is to analyze the impact of physical inactivity from middle age to early old age on functional ability at age 75. Physical activity is measured both as cumulated activity from age 50 to 60 to 70 and at three separate points in time. Three hundred eighty-seven men and women born in 1914 and living in seven municipalities in the western part of the County of Copenhagen were followed for 25 years with examinations in 1964, 1974, 1984 and 1989. Analyses were conducted with physical inactivity as an independent variable (accumulated and separately for each point in time) and smoking, sex, school education, household composition, chronic disease at baseline and functional ability at age 70 as possible confounders. There was a strong association between physical inactivity at age 70 and disability at age 75. However, the analyses showed no effect of cumulated physical inactivity from age 50 to 60 to 70 on disability at age 75 when adjusting for functional ability at age 70. Physical inactivity is a risk factor for disability among old people. Thus, old people should be encouraged to take up and maintain physical training throughout the aging process.

Communication and coping as predictors of fertility problem stress: cohort study of 816 participants who did not achieve a delivery after 12 months of fertility treatment.

BACKGROUND: We investigated coping strategies and communication strategies as predictors of fertility problem stress 12 months after start of fertility treatment. METHODS: We used a prospective, longitudinal cohort design including 2250 people beginning fertility treatment with a 12-month follow-up. Data were based on self-administered questionnaires measuring communication with partner and with other people, coping strategies: active-avoidance coping, active-confronting coping, passive-avoidance coping, meaning-based coping, and fertility problem stress. The study population included those participants (n = 816, men and women) who had not achieved pregnancy by assisted reproduction or delivery at follow-up. RESULTS: Among both men and women, difficulties in partner communication predicted high fertility problem stress (odds ratio for women, 3.47, 95% confidence interval 2.09-5.76; odds ratio for men, 3.69, 95% confidence interval 2.09-6.43). Active-avoidance coping (e.g. avoiding being with pregnant women or children, turning to work to take their mind off things) was a significant predictor of high fertility problem stress. Among men, high use of active-confronting coping (e.g. letting feelings out, asking other people for advice, seeking social support) predicted low fertility problem stress in the marital domain (odds ratio 0.53, 95% confidence interval 0.28-1.00). Among women, medium or high use of meaning-based coping significantly predicted low fertility problem stress in the personal and marital domain. CONCLUSION: The study provides information about where to intervene with fertility patients in order to reduce their stress after medically unsuccessful treatment.

Anaesthesia-induced hyperglycaemia early in life is not predictive for development of diabetes in diabetes-prone BB rats.

Type 1 diabetes (T1D) is an autoimmune disease in genetically predisposed individuals characterised by selective destruction of the beta-cells. Development of diabetes is in the asymptomatic pre-diabetic period characterised by impaired first-phase insulin response and the first clinical symptom is elevated blood glucose (BG). It is still uncertain whether stress or incidental hyperglycaemia can be regarded as predictors for development of T1D or not, even when immunologic and genetic markers for T1D are considered. The aim of this study was to investigate if there was any relationship between elevated BG in 30-day-old anaesthetised pre-diabetic diabetes-prone Bio Breeding (BB-DP) rats and later development of diabetes. Rats anaesthetised by intraperitoneal (ip) injection for islet transplantation displayed significantly higher BG values (Delta1.27 mmol/l, p=8.27x10(-12)) compared to non-anaesthetised non-transplanted rats, indicating that ip injection and/or anaesthesia induce a higher BG level. Linear regression analysis of BG and time of onset of diabetes in transplanted and non-transplanted BB-DP rats revealed no correlation (R(2) at 0.0075 and 0.0324 and p-values at 0.56 and 0.23 respectively). We were not able to identify any association or correlation between the induced temporary hyperglycaemia in 30-day-old BB-DP rats and later development of diabetes.

The social epidemiology of coping with infertility.

BACKGROUND: To analyse the cross-sectional association between coping responses with infertility and occupational social class. Infertility is evenly distributed across social classes in Denmark, and there is free access to high-quality assisted reproduction technology. METHODS: Data were based on a questionnaire in a consecutive sample of 1169 women and 1081 Danish men who were about to begin assisted reproduction treatment. The coping measure was developed from an adaptation of Lazarus and Folkman's Ways of Coping Questionnaire and based on results from interviews with infertile people. The measure was developed in four categories: active-avoidance coping; active-confronting coping; passive-avoidance coping; meaning-based coping. These subscales were later confirmed by factor analysis. Occupational social class was measured in a standardized way. RESULTS: Contrary to expectations, the logistic regression analyses showed that women from lower social classes V + VI and men from social classes III + IV used significantly more active-confronting coping. Women from lower social classes V + VI used significantly more meaning-based coping. Both men and women from social classes III - VI used significantly more passive-avoidance coping and significantly less active-avoidance coping. CONCLUSION: Due to the significant social differences in coping with infertility, the study suggested that elements of coping may be learned from one's social network and reference group.

Changes in expression of IL-1 beta influenced proteins in transplanted islets during development of diabetes in diabetes-prone BB rats.

AIMS/HYPOTHESIS: Type 1 diabetes mellitus is a multifactorial autoimmune disease characterised by selective destruction of beta cells in the islets of Langerhans. We have previously shown that IL-1 beta modulates beta cell function, causes beta cell death and induces expression changes in 82 out of 1815 protein spots detected by two-dimensional gel electrophoresis (2-DGE) in diabetes-prone bio-breeding (BB-DP) rat islets in vitro. The aim of this study was to describe the relevance of these proteins in the development of diabetes in vivo. METHODS: Syngeneic neonatal islets ( n=200) were transplanted under the kidney capsule of 30-day-old BB-DP and control rats, removed to different time points after transplantation or at the onset of diabetes, and metabolically labelled with S(35)-methionine for 2-DGE. The 82 proteins were re-localised and followed. In addition, transplants were examined for expression of IL-1 beta mRNA by in situ hybridisation. RESULTS: All 82 proteins could be re-localised in all syngeneic transplants from BB-DP and control rats. A total of 60 of the 82 proteins were changed during development of diabetes. Of the 82 proteins, 32 were changed in expression at the onset of diabetes compared to non-diabetic BB-DP rats, and 25 of these were changed as by IL-1 beta in vitro. Highest expression of IL-1 beta mRNA was found at the onset of diabetes. CONCLUSIONS/INTERPRETATION: IL-1 beta-induced protein expression changes in islets in vitro also occur in vivo and change in a complex pattern during the development of diabetes in the BB-DP rat. No single protein seems to be responsible for the development of diabetes, but rather the cumulative numbers of changes seem to interfere with the intracellular stability of the beta cell.

High local unemployment and increased mortality in Danish adults; results from a prospective multilevel study.

AIMS: To examine the relation between unemployment rates in area of residence and all-cause mortality, taking the individuals' unemployment experience and a number of social and behavioural factors into account. METHODS: Prospective cohort study with record linkage to mortality and unemployment registers. Data were pooled data from two population studies conducted in Copenhagen, Denmark. The association between unemployment at parish level and mortality was examined in Cox proportional hazard analysis. A total of 15 980 men and women, aged 20-67 years and employed at 1 January 1980, were studied. All-cause mortality was followed from January 1981 to December 1998. RESULTS: The unemployment rate in the area of residence was associated with increased mortality (hazard ratio(highest v lowest quartile) 1.35:0.14-1.60) even after adjustment for individuals' unemployment experience in 1980, which was also a risk factor (hazard ratio(yes/no) 1.38:1.16-1.64). These estimates attenuated somewhat when other social and behavioural covariates were taken into account. The effects were similar in men and women, but the influence of individuals' unemployment experience during one and five years decreased gradually with increasing age. CONCLUSION: This prospective study suggests that high local unemployment and individuals' experience of unemployment increase mortality risk, even after adjustment for other social and behavioural factors.
