Objective: The objective of this study is to investigate the impact of metabolic status on associations of serum vitamin D with hypogonadism and lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH).

Patients and methods: A total of 612 men underwent physical examination, biochemical/hormonal blood testing, and transrectal prostate ultrasound. Moreover, the subjects filled out standard questionnaires for identification and grading of LUTS and hypogonadism symptoms. Parameters were statistically compared with independent t-tests and correlation analyses.

Results: Vitamin D levels positively correlated with total testosterone (TT) but not with prostate volume or International Prostate Symptom Score (IPSS). Patients with metabolic syndrome had significantly lower vitamin D levels, which were not correlated with TT, prostate volume, or IPSS. However, vitamin D was positively correlated with TT, and negatively correlated with prostate volume and quality-of-life IPSS in subjects without metabolic syndrome.

Conclusion: The clinical usefulness of vitamin D for treatment of hypogonadism or LUTS/BPH varies according to metabolic status.  相似文献

Disabled asylum seekers have been found to often experience extreme deprivation. Possible causes and solutions are explored, drawing on the experiences of disabled asylum seekers themselves as well as on a series of interviews with people working in the asylum and immigration sector. It is suggested that action is required to reduce immediate suffering, but that systemic change is needed to address the causes of this deprivation.  相似文献

In France the chairperson of the board is mostoften the firm's CEO. This position strengthensthe insiders' hold on the board of directors.Moreover, a large fraction of outside directorsis composed of CEOs of other firms. Thereciprocal interlocking of CEOs creates the possibility of mutual interdependence of CEOs.We investigate factors explaining reciprocalinterlocking directorates of CEOs in Frenchcorporations. Our results indicate that CEOs oflarger firms hold more reciprocal CEOinterlocks and when CEOs have more outsidedirectorships, CEOs hold more reciprocalrelationships. We also find a positiverelationship between the number of CEOsreciprocal interlocks and their firms'performance measured by ROA. We find evidencethat CEOs hold more reciprocal interlocks whena blockholder is present on the CEO's board.  相似文献

As demographic shifts make the Social Security program financially vulnerable, the responsibility for income security in old age will shift from the government to elderly people. In this changing environment, the accumulation of wealth will be a crucial issue because wealth holders can draw income from assets, which can supplement retirement income. Thus, wealth (or net worth) is a proximate indicator of economic well-being of the elderly. This article presents the findings of a study of the net worth of elderly people with disabilities. The major findings were that a smaller proportion of elderly people with disabilities has assets of any type compared with elderly people with no disability; the dollar value of each type of asset is smaller among elderly people with disabilities than among elderly people with no disability; and the net worth of people with disabilities is smaller than that of elderly people with no disability even after other variables were controlled.  相似文献

Traditionally, IT security investment decisions are made in isolation. However, as firms that compete for customers in an industry are closely interlinked, a macro perspective is needed in analyzing these decisions. We utilize the notions of direct‐ and cross‐risk elasticity to describe the customer response to adverse IT security events in the firm and competitor, respectively, thus allowing us to analyze optimal security investment decisions. Examining both symmetric and asymmetric duopoly cases using a continuous‐time Markov chain (CTMC) model, we demonstrate that optimal IT security spending, expected firm profits and willingness of firms to cooperate on security improvements are highly dependent on the nature of customer response to adverse events. We also examine the investment problem when security attacks on different firms are correlated.  相似文献

AimThe aim of this paper is to describe the factors that impact on the mental health of Australian and New Zealand (NZ) women in the perinatal period (pregnancy and the year following birth), and to determine the impact of perinatal mental health on women's subsequent health by summarising findings from prospective longitudinal studies conducted in Australia and NZ.MethodsA systematic search was conducted using the databases, Scopus, Medline, PsychInfo and Health Source to identify prospective longitudinal studies focused on women's social and emotional health in the perinatal period. Forty-eight papers from eight longitudinal studies were included.ResultsThe proportion of women reporting depressive symptoms in the first year after birth was between 10 and 20% and this has remained stable over 25 years. The two strongest predictors for depression and anxiety were previous history of depression and poor partner relationship. Importantly, women's mood appears to be better in the first year after birth, when compared to pregnancy and five years later. Becoming a mother at a young age is by itself not a risk factor unless coupled with social disadvantage. Women report a high number of stressors in pregnancy and following birth and the rate of intimate partner violence reported is worryingly high.ConclusionMidwives have an important role in the identification, support and referral of women experiencing mental health problems. As many women do not seek help from mental health services, the potential for a known midwife to impact on women's mental health warrants further examination.  相似文献

This study examined attitudes about social acceptance, discrimination protection, and marriage equality for gay/lesbian people with a representative sample of 1,008 Hong Kong Chinese adults via a telephone survey. Despite majority endorsement of homosexuality (52.29% positive vs. 34.12% negative) and discrimination protection (50.72% favorable vs. 14.64% opposed), attitudes toward same-sex marriage diverged (32.79% favorable vs. 39.41% opposed). There was a sharp distinction in accepting gay/lesbian people as co-workers (83.57%) and friends (76.92%) versus relatives (40.19%). Having more homosexual/bisexual friends or co-workers contributed to greater endorsement of social acceptance and discrimination protection but not same-sex marriage. Age, religion, political orientation, and homonegativity consistently predicted attitudes toward social acceptance, discrimination protection, and same-sex marriage, whereas gender-role beliefs, conformity to norms, and cultural orientations had varying impacts. This article informs theory and advocacy by disentangling homonegativity from attitudes about gay/lesbian issues and highlighting the centrality of family-kinship and relative-outsider delineation in Chinese societies.  相似文献

Uncivil comments following online news articles about issues of science and technology have been shown to lead to biased interpretations of the news content itself. Using an experiment embedded in a nationally representative survey, we provide evidence that cues about comment moderation ? even without any change in the comments themselves ? have the potential to alleviate this so-called nasty effect. Participants exposed to uncivil comments that appear in a moderated environment were less likely to perceive bias in the news article itself. Importantly, perceptions of bias among respondents exposed to the uncivil, moderated stimulus were comparable to those of respondents who viewed both moderated and unmoderated civil comments. Our results suggest that visible cues about comment moderation are a potentially valuable endeavor for news organizations, especially in an age of declining profit margins.  相似文献
