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
ABSTRACTCyber-safety behaviors are important in preventing the loss of an individual's digital assets and ensuring the safety of important daily online activities. Individuals’ cyber-safety is also critical for national cybersecurity. The issue is highly relevant for Israel, a country that relies on the digital capabilities of its workers for its major technology industries and is also often a target of cyberwarfare and cybercrime attacks. The purpose of this study is to identify the determinants of cyber-safety behavior. We investigate the role of age, gender and education in the use of safety-related digital skills and antivirus software. Using a 2014 survey of a national sample of Internet users in Israel (N?=?1850), we found that age, gender, education and quality of access are associated with the level of users’ digital security skills. In addition, these skills and the frequency of conducting financial activities online are the main determinants of antivirus behaviors. Our results expand the understanding of cyber-safety by showing that social and digital disparities are reproduced in the use of measures to prevent online threats, putting the digitally disadvantaged at greater risk of becoming victims of online threats. 相似文献
ABSTRACTThe debate about the power and influence of networked publics often focuses on large-scale political events, activist campaigns and protest activity – the more visible forms of political engagement. On the other hand, digitally mediated activism is often questioned and sometimes derided as a lesser form of dissent, as it is easier to engage in, highly affective, and offers few assurances of sustainability of the change it calls for. But what about everyday political speech online, where social media platforms can contribute to a personalisation of politics? Can social media users express their views online and make a difference? This paper analyses around 3500 Facebook posts stemming from the #ЯНеБоюсьСказати (Ukrainian for #IAmNotAfraidToSayIt) online campaign that was started in the Ukrainian segment of Facebook in July 2016 by a local activist to raise awareness of how widespread sexual violence and sexual harassment are in the Ukrainian society. The paper argues that networked conversations about everyday rights and affective stories about shared experiences of injustice, underpinned by the affordances of social media platforms for sharing and discussing information and participating in everyday politics, can emerge as viable forms of networked feminist activism and can have real impact on the discursive status quo of an issue, both in the digital sphere and beyond it. 相似文献
ABSTRACTThis paper will argue that 3D digital animation, unlike its 2D and stop-motion counterparts, currently lacks recognisable self-reflexive aesthetic devices through which the trace of animators’ labour can be made visible. It will open with a brief history of how animation has previously shown its workings; from the pencil-wielding hand of Émile Cohl to the opening seconds of South Park, plus the intentional and unintentional smears and multiples visible on animation cells. These devices will then be discussed in relation to Marx’s analysis of the commodity in Capital Vol. 1, and how the process of fetishisation is momentarily disrupted by imperfections in the object which have been caused by production errors. These faults reconnect the object to its producer through the trace of (imperfect) labour which remains visible on the surface. In animation, similar (albeit consciously made) ‘errors’ connect the perceptive viewer directly to the work of 2D or stop-motion animators. This paper will argue the need for an equivalent to emerge in 3D digital animation, as well as highlighting some contemporary animators testing and subverting the limits of 3D and sketching some possible ways these might encourage further formal innovations. 相似文献
3D printing (3DP) has been heralded as a revolutionary technology that can alter the way production is organized across time and space – with important redistributive effects on geography and size of production activities. In this article, we examine the impacts that a widespread adoption of 3DP could have on restructuring, upgrading and distributing value added along manufacturing global value chains (GVC) – with brief examples from the aerospace and automotive industries. We highlight two possible scenarios for GVCs – a complementarity scenario of 3DP and traditional manufacturing overlapping, which would reproduce power relations in GVCs and the current distribution of value added in a ‘smiling curve’; and a substitution scenario of 3DP partly or fully superseding traditional manufacturing, which would have more transformational effects in terms of ‘rebundling’ activities, regionalizing or localizing GVCs, and flattening the smiling curve into a ‘smirk’. 相似文献
BackgroundIn the Palestinian community, lifestyle changes, rapid urbanization and socioeconomic development, stress, smoking, and changes in food habits has increased the risk of non-communicable diseases especially diabetes mellitus. Diabetes complications can be prevented if the glycemic status of patients with diabetes is maintained within a nearly normal range. Therefore, patient education is critical in controlling blood glucose levels within the normal range.ObjectiveThis study aimed at measuring the effect of diabetes educational intervention program for patients suffering from type 2 diabetes attending the Diabetes Clinic in Tulkarim Directorate of Health.MethodsA short duration observational study involving pre- and post-test educational intervention program was carried out on a relatively small number of type 2 diabetes patients at the Diabetes Clinic in Tulkarim Directorate of Health. In total, 215 patients attended a group-based 4 h educational intervention session about diabetes. The program included explaining diabetes mellitus-symptoms, risk factors, types, treatment and complications and main aspects of self-care of the disease (foot care, eye care, and blood glucose monitoring), main aspects of dietary management, weight reduction, blood pressure, smoking cessation, periodic investigations, home monitoring and importance of physical activity. Knowledge evaluation questionnaire were evaluated pre- and post-study. Anthropometric measurements such as body weight (WT), body mass index (BMI) and laboratory tests such as fasting blood glucose (FBG), hemoglobin A1C (HbA1c), cholesterol (Chol), and triglycerides (TG) were measured both at the beginning and at the end of the study. Significance of the results was assessed by paired t-test at 95% confidence interval.ResultsThe participant’s mean age was 51.07 that ranged between 31 and 70 years. For a total of 215 participants, 41.4% were males and 58.6% were females. The mean weight before educational intervention was 80.81 ± 14.95 kg (82.6 kg for males and 79.5 kg for females) that decreased to 78.9 ± 14.33 kg (81.1 kg for males and 77.3 kg for females) after educational intervention program. The BMI also decreased significantly after educational intervention. The mean fasting blood sugar was 188.65 ± 71.45 mg/dL before educational intervention that decreased to 177.7 ± 66.11 mg/dL after the educational intervention (p = 0.049). The mean glycosylated hemoglobin was 8.57 ± 1.21 before educational intervention that decreased to 7.95 ± 1.42 after educational intervention. The mean value of cholesterol before educational intervention was 183.27 ± 37.74 mg/dL that decreased to 169.57 ± 34.23 mg/dL after educational intervention. The mean triglycerides value decreased after educational intervention from 209.85 ± 171.04 mg/dL to 183.28 ± 152.4 mg/dL (p = 0.025). The mean score of knowledge questionnaire before educational intervention was 60.6 ± 20.65 that increased to 78.1 ± 13.4 after conducting educational intervention.ConclusionsDiabetes education was found to be effective on BMI, FBG, HbA1c, Chol, TG, and knowledge.RecommendationsDiabetes education is a cornerstone in the management and care of diabetes and should be an integral part of health planning involving patient’s family, diabetes care team, community, and decision makers in the education process. 相似文献
Integration into the information society implies that information plays an increasingly important role in all sectors of society and holds distinct social and economic benefits. Discourses on the information society are, however, also associated with the digital divide and inequalities in access to and use of information and communication technologies (ICTs). Within sub-Saharan Africa, South Africa is often regarded as one of the most information-integrated societies due to widespread mobile phone ownership, among other things. However, while ICT access has been emphasized, research also points to the role of demographic, socio-economic and cultural factors such as ethnicity, income, education and gender. This article discusses the results of questionnaire surveys conducted by Afrobarometer among probability South African samples in 2008 and 2011. The results indicate that individual Internet use and mobile Internet access were lower than estimated in the literature. Furthermore, gender gaps, as well as considerable gaps between population groups and educational levels, were found in Internet and computer use, mobile ownership and access to mobile Internet and accessing news via the Internet. Conclusions regarding strategies for bridging the digital divide and integrating South Africa into the information society are discussed. 相似文献
This paper explores how online actions such as the practice of digital self-writing shape our offline identity. We start with an examination of the concept of hupomnemata – a practice of self-writing in which notes are kept as a ‘material record of things read, heard, or thought’ in the intent of shaping the self [Foucault (1997). Self writing. In P. Rabinow (Ed.), Ethics, subjectivity and truth. The essential works of Foucault, 1954–1984. Volume 1 (pp. 207–222). New York, NY: The New Press p. 209] – before arguing that the practice of digital content curation can be understood as a modern-day variant of the Greco-Roman hupomnemata. Although the work of the digital curator is conducted online, this paper positions contemporary curatorial practices as acts of self-exploration, self-cultivation, and self-care, which nourish offline identity and which ultimately work to shape the offline, corporeal self. 相似文献
