Background and Objectives: Few population-based data on the prevalences of masked and white-coat hypertension exist. We collected 24-hour ambulatory blood pressure (BP) and urine in a random subset of participants to the population-based CoLaus study. Methods: Clinic BP was measured using an Omron HEM 907 device and ambulatory BP (ABP) using a Diasys Integra device. Masked hypertension (MH) was defined as clinic BP < 140/90mm Hg and 24-hour ABP >¼135/85mmHg. White coat hypertension (WCH) was defined as clinic BP >¼ 140/90mm Hg and ABP <135/85mm Hg. Microalbuminuria was defined as present if urinary albumin excretion was > 20mg/min. Results: The 198 men and 213 women were aged (mean_SD) 56.2_10.7 and 57.2_10.3 years and had mean urinary excretion of 148_65 and 122_52 mmol/24 h for sodium and 70_24 and 5721 mmol/24 h for potassium, respectively. In men and women, the prevalences were 34.9% and 31.0% for clinic hypertension, 42.9% and 32.9% for ambulatory hypertension, 12.6% and 5.6% for MH, and 4.5% and 3.8% for WCH, respectively. The higher prevalence of MH in men was explained, in part, by higher alcohol consumption and smoking. Participants with MH tended to have higher microalbuminuria (13.5% vs 5.8%, P¼0.067). Participants with WCH had no microalbuminuria. Conclusions: In the Lausanne population aged 38 to 78 years, the prevalence of hypertension based on ABP was high, despite moderate dietary salt intake. Men had higher prevalence of MH then women. The prevalence of WCH was low and similar in men and women. MH tended to be associated with early kidney damage.

In order to investigate the determinants of effective population size in the socially monogamous Crocidura russula, the reproductive output of 44 individuals was estimated through genetic assignment methods. The individual variance in breeding success turned out to be surprisingly high, mostly because the males were markedly less monogamous than expected from previous behavioural data. Males paired simultaneously with up to four females and polygynous males had significantly more offspring than monogamous ones. The variance in female reproductive success also exceeded that of a Poisson distribution (though to a lesser extent), partly because females paired with multiply mated males weaned significantly more offspring. Polyandry also occurred occasionally, but only sequentially (i.e. without multiple paternity of litters). Estimates of the effective to census size ratio were ca. 0.60, which excluded the mating system as a potential explanation for the high genetic variance found in this shrew's populations. Our data suggest that gene flow from the neighbourhood (up to one-third of the total recruitment) is the most likely cause of the high levels of genetic diversity observed in this shrew's subpopulations.

Backgroud: Household service work has been largely absent from occupational health studies. We examine the occupational hazards and health effects identified by immigrant women household service workers. Methods: Exploratory, descriptive study of 46 documented and undocumented immigrant women in household services in Spain, using a phenomenological approach. Data were collected between September 2006 and May 2007 through focus groups and semi-structured individual interviews. Data were separated for analysis by documentation status and sorted using a mixed-generation process. In a second phase of analysis, data on psychosocial hazards were organized using the Copenhagen Psychosocial Questionnaire as a guide. Results: Informants reported a number of environmental, ergonomic and psychosocial hazards and corresponding health effects. Psychosocial hazards were especially strongly present in data. Data on reported hazards were similar by documentation status and varied by several emerging categories: whether participants were primarily cleaners or carers and whether they lived in or outside of the homes of their employers. Documentation status was relevant in terms of empowerment and bargaining, but did not appear to influence work tasks or exposure to hazards directly. Conclusions:Female immigrant household service workers are exposed to a variety of health hazards that could be acted upon by improved legislation, enforcement, and preventive workplace measures, which are discussed.

This is an exploratory research, with a quantitative approach, developed with the objective of analyzing the work and of life situations that can offer risks to the workers' health involved in the manual and automated cut of the sugar cane. The sample was composed by 39 sugar cane cutters and 16 operators of harvesters. The data collection occurred during the months of July and August of 2006, by the technique of direct observation of work situations and workers' homes and through interviews semi-structured. The interviews were recorded and later transcribed. Data were analyzed according to Social Ecological Theory. It was observed that the workers deal with multiple health risk situations, predominantly to the risks of occurrence of respiratory, musculoskeletal and psychological problems and work-related accidents due to the work activities. The interaction of individual, social and environmental factors can determine the workers' tendency to falling ill.

Exact closed-form expressions are obtained for the outage probability of maximal ratio combining in η-μ fadingchannels with antenna correlation and co-channel interference. The scenario considered in this work assumes the joint presence of background white Gaussian noise and independent Rayleigh-faded interferers with arbitrary powers. Outage probability results are obtained through an appropriate generalization of the moment-generating function of theη-μ fading distribution, for which new closed-form expressions are provided.

Within pre-enlargement Europe, Italy records one of the widest employment rate gaps between highly and poorly educated women, as well one of the largest differences in the share, among working women, of public sector employment. Building on these stylized facts and using the Longitudinal Survey of Italian Households (ILFI), we investigate the working trajectories of three cohorts of Italian women born between 1935 and 1964 and observed from their first job until they are in their forties. We use mainly, but not exclusively, event history analysis in order to identify the main factors that influence entry into and exit from paid work over the life course. Our results suggest that in the Italian context, where employment protection policies have also been used as surrogate measures to favour reconciliation between family and work, and where traditional gender norms still persist, education is so important for women's employment decisions because it represents an investment in 'reconciliation' and 'work legitimacy' over and above investment in human capital.
