Is Hba1c level of diabetic patients associated with penile prosthesis implantation infections?

Background and objectives: Diabetes mellitus is an important risk factor for erectile dysfunction (ED). Penile prosthesis implantation surgery is the final solution for diabetic patients with ED, but infections thereof are still a serious risk factor. While some studies suggest that most infections associated with penile prosthesis implantation are associated to high glycated hemoglobin (HbA1c) levels, other research did support such relationship.

Materials and methods: The current study assessed retrospectively, the association between HbA1c level and penile prosthesis surgery infection. We retrieved and reviewed the records of 300 diabetic patients who had penile prosthesis surgery at our Institution (January 2012–November 2016). Patients’ mean age was 55.26?±?10.9 years (31% patients were <50 years of age), and mean HbA1c was 7.60?±?1.90%.

Results: Infection rate among diabetics was 0.67%. Prevalence of prosthesis infection among patients with HbA1c?≤?9% was 0.9%, compared with 0% among patients with HbA1c?>?9%. Prosthesis infection risk did not significantly increase with higher HbA1c levels, with no meaningful difference in the median or mean level of HbA1c in the infected and non-infected diabetic patients.

Conclusion: Findings do not support the use of HbA1c values among diabetic patients who are candidates for penile prosthesis implantation surgery in order to identify and exclude those who might be prone to increased risk of prosthesis infections. Future studies would benefit from larger sample sizes in order to support or refute our findings.

Entrepreneurship among the Displaced and Dispossessed: Exploring the Limits of Emancipatory Entrepreneuring

This paper explores the links between entrepreneurship, emancipation and gender within the international development arena. Through a longitudinal analysis of a micro‐enterprise development project in which intermediary organizations contract traditional handicrafts from female home‐based producers, we focus on the impact of contracting policies on the ability of the desperately poor to improve their disadvantaged position. Our critical analysis reveals how intermediaries who impose exclusive contracting conditions, supposedly to protect the women's interests, actually constrain the emancipatory potential of the women's entrepreneurial activities. However, such contractual limitations generate collaborative networks enabling the women to challenge these constraints in an effort to assert control over their activities. Accordingly, this paper contributes to contemporary debates concerning the emancipatory potential of entrepreneurship within the context of development. We advance this analysis through a gendered evaluation of the role of intermediary organizations on entrepreneurial emancipation and related empowerment.     

Experiences of Purpose in Life When Becoming and Being a Very Old Woman

The aim of the study was to illuminate how very old women describe their experiences of purpose in life (PIL) in narratives about becoming and being very old. The participants comprised 30 women selected from 120 women who had answered the PIL test and had been interviewed about their experiences of being very old. The interviews were analyzed with qualitative content analysis, which revealed four themes: having a positive view of life, living in relation to God, having meaningful activities, and simply existing. Our findings show that very old women experience purpose in life both in their daily activities and in their contact with a spiritual world. It seems to be facilitated by a positive view of life. Although the results were dominated by a positive view of life, some of the participants saw their lives in terms of simply existing, and did not experience purpose in life.     

Detection of outliers in high-dimensional data using nu-support vector regression

Support Vector Regression (SVR) is gaining in popularity in the detection of outliers and classification problems in high-dimensional data (HDD) as this technique does not require the data to be of full rank. In real application, most of the data are of high dimensional. Classification of high-dimensional data is needed in applied sciences, in particular, as it is important to discriminate cancerous cells from non-cancerous cells. It is also imperative that outliers are identified before constructing a model on the relationship between the dependent and independent variables to avoid misleading interpretations about the fitting of a model. The standard SVR and the μ-ε-SVR are able to detect outliers; however, they are computationally expensive. The fixed parameters support vector regression (FP-ε-SVR) was put forward to remedy this issue. However, the FP-ε-SVR using ε-SVR is not very successful in identifying outliers. In this article, we propose an alternative method to detect outliers i.e. by employing nu-SVR. The merit of our proposed method is confirmed by three real examples and the Monte Carlo simulation. The results show that our proposed nu-SVR method is very successful in identifying outliers under a variety of situations, and with less computational running time.     

Covering the birth of a nation: The rise of Saudi Arabia in The London Times, 1927–1937

Saudi Arabia is considered as one of the most conservative countries in the world with regards to the role of religion in shaping national politics. We use a history of Saudi Arabia and British imperialist policy to contextualize the framing of religion in news coverage of Saudi Arabia in The London Times between 1927 and 1937 to uncover themes that were available to British readers before and after recognizing Saudi Arabia as a nation on September 23, 1932. We found that religious fundamentalism was part of this coverage, providing one potential media framework for understanding Saudi Arabia that is consistent with current coverage and discussions. We also found instances of favorable framing of events and individuals, which seemed to intensify after Saudi Arabia's recognition as a nation.
