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.     

On functional central limit theorems of Bayesian nonparametric priors

A general approach to derive the weak convergence, when centered and rescaled, of certain Bayesian nonparametric priors is proposed. This method may be applied to a wide range of processes including, for instance, nondecreasing nonnegative pure jump Lévy processes and normalized nondecreasing nonnegative pure jump Lévy processes with known finite dimensional distributions. Examples clarifying this approach involve the beta process in latent feature models and the Dirichlet process.     

‘Being young and LGBT,what could be worse?’ Analysis of youth LGBT activism in Indonesia: challenges and ways forward

Young Indonesian LGBT people are currently mobilising against a wave of conservatism and violence in an increasingly anti-LGBT context. Young LGBT people are showing remarkable courage and strategic thinking and mobilising in a range of ways. These include grassroot peer support, advocacy, and partnerships with government, adult-led non-government organisations and the private sector. However, these youth also face multiple challenges. This article highlights findings from a 2016 study of mobilisation by youth LGBT activists, using in-depth feminist qualitative research methods. The aim of the research was to highlight the resilience of young LGBT people in Indonesia, the barriers they face, and to consider what feminists and development policymakers and practitioners can do to support them.     

Logistic Regression Analysis of the Outlook of People in Turkey Regarding the Principles of Secularism and Republic for the New Constitution to be Prepared

This paper studies demands and expectations of people about the content of the new constitution supposed to be prepared after the parliamentary election of June, 2011 in Turkey. For that purpose, a survey was applied across the country to 6,810 people with different ethnic identities, religious faiths and political tendencies. Economic and social conditions of the respondents were studied and subsequently their tendencies regarding two of the most frequently discussed topics of the country namely Secularism and Republic were explored. For that purpose, statistical technics and the logistic regression technic were used. We interestingly found out that the two principles mentioned above have been substantially accepted by different parts of the society and there are no considerable negative reactions regarding those issues. It was found out in this study that almost all parts of the Turkish society accept some fundamental principles of the regime like Republic and Secularism as well as the Presidency of Religious Affairs. It appears that in Turkey basic differences regarding perspectives on political and social values arise rather from sectarian identities.     

Temporary Labour–Migration System and Long–term Residence Strategies in the United Arab Emirates

The United Arab Emirates’ migration system, the sponsorship–based kafala system, is defined as a temporary labour–migration regime. Although there are policies making permanent residence unattainable for virtually all migrants, it is still relevant to explore the temporality of migrations in the UAE. The purpose of this study is to investigate developments in migration, migration policies and population trends in the country, including trends that concern the duration of migrants’ stay. We also identify some of the major strategies used by migrants to prolong their sojourn in the UAE. It is maintained that the migrant stock has increased continuously in the last decades and that a large number of migrants devise strategies to continue their residence and remain in the country for years. The authors also identify and discuss migrants’ transition within and in-between regularity and irregularity, and analyse the reasons for utilizing different strategies over time.     

A two‐step proximal‐point algorithm for the calculus of divergence‐based estimators in finite mixture models

Estimators derived from the expectation‐maximization (EM) algorithm are not robust since they are based on the maximization of the likelihood function. We propose an iterative proximal‐point algorithm based on the EM algorithm to minimize a divergence criterion between a mixture model and the unknown distribution that generates the data. The algorithm estimates in each iteration the proportions and the parameters of the mixture components in two separate steps. Resulting estimators are generally robust against outliers and misspecification of the model. Convergence properties of our algorithm are studied. The convergence of the introduced algorithm is discussed on a two‐component Weibull mixture entailing a condition on the initialization of the EM algorithm in order for the latter to converge. Simulations on Gaussian and Weibull mixture models using different statistical divergences are provided to confirm the validity of our work and the robustness of the resulting estimators against outliers in comparison to the EM algorithm. An application to a dataset of velocities of galaxies is also presented. The Canadian Journal of Statistics 47: 392–408; 2019 © 2019 Statistical Society of Canada     

Handwheel valve operation: assessment of four opening methods in terms of muscle loading, perceived comfort, and efficiency

Injuries due to manual valve handwheel operations are a major concern in the chemical process industry. Manual valves are used to start, stop, and control flow in process lines. The torque required to operate handwheels after the initial "breaking" can vary due to the size, design, and condition of the valve. This study tested four methods of turning the handwheel on a medium-sized gate valve at two different torque requirements (25 Nm and 50 Nm). The methods were compared to each other, in terms of efficiency, subjective ratings of perceived exertion, and electromyography activity of the upper extremity and trunk muscles. The results indicate that different methods and torque requirements are compensated for by the use of different muscles. Also, this use of different muscles, along with the increased mechanical advantage of the wrench, can affect the operator's actual and perceived comfort and efficiency while operating a valve handwheel.     

Penalized multidimensional fitting for protein movement detection

The three-dimensional structure of a given protein can take different conformations depending upon the reaction it undergoes and its substrate/cofactor/partners binding state. Various methods exist to study these conformational changes but only one, called DynDom, is clearly focused on movement detection. An alternative method is proposed, making use of multivariate data analysis, called ‘penalized Multidimensional Fitting (penalized MDF)’ based on penalized movements of points in order to approach the distances between points after movement to the distances given by the reference matrix. The objective is to detect the amino acids that undergo an important movement by fitting the distances of one conformation to the distances of the second one by modifying only the coordinates of the first one. This method is applied to three different proteins.     

Social behavior practices for child protection and well-being among low-income urban households in Bangladesh

The main objective of this study was to explore the status of social behavior practices for child protection and well-being among low-income urban households in Bangladesh. This study used a survey method, and data were collected through a face-to-face structured interview from 378 low-income household heads from 12 wards (Konabari and Kashimpur) of Zone 5 of the Gazipur City Corporation. Results found that the current status of the presence of child protection services is very low (in many cases, this number is zero except children having birth registered). A significant number (55%) of them were married between 15 and 19 years. The study found a low level of access on the components of social behaviors where around 50% to 60% caregivers stated 4 benefits of key behaviors, necessity of hand washing after defecation and before and after taking a meal, the age of boys and girls to get married off, and know the effect and consequences of child marriage. The chi-squared tests confirmed extremely high significance in almost all of the components. Findings will be an important guideline for the policymakers, child service practitioners, and human rights workers.
