title: The recent geodynamics of Haitian migration in the Americas: refugees or economic migrants?

description: Abstract After having presented the specific migration context of Haiti and its multidimensional vulnerability, this paper shows that the diaspora geography explains, to a large extent, the location of Haitian refugees and asylum seekers in North America and the French Caribbean territories. Then, we explore the relation between migration policy evolution and the development of new migration routes towards South America, where the recognition of the multidimensional nature of this migration has paved the way for the legalization of Haitian migrants, particularly in Brazil. The complementary migration functions of Ecuador, Peru, Brazil and Chile created a new regional migration system centered on the Southeast and the South of Brazil. This emerging South-South migration route is part of a larger Haitian migration system that connects Latin America to North America and the Caribbean.

title: Effects of body mass index on the outcomes of percutaneous nephrolithotomy

description: ABSTRACT Objective To examine the the effect of body mass index (BMI) on PNL results and complications with a large number of patients. Materials and Methods A total of 958 patients were included in the study, who underwent percutaneous nephrolithotomy in our clinic between 2008 and 2015. Patients were divided into 2 groups according to their body mass index. Patients with a BMI &lt; 30 kg/m2 were classified as group 1 (n:676) and patients with a BMI ≥ 30 kg/m2 were classified as group 2 (n:282). Achieving stone-free status or having residual stones of ≤ 4 mm were considered as operational success. Results The mean age was 47.9 years for group 1 and 48.9 years for group 2 patients. At postoperative first month CT analysis, residual stone was not observed in 466 patients (69%) of group 1 and 20 (72%) patients of group 2. There was no significant difference between the groups in terms of stone-free status (p=0.348). There was no significant difference between two groups complications. Also, there was no difference between the groups for requiring additional intervention (p=0.924). No other complications were observed in the patients. Conclusions BMI does not affect the outcomes of percutaneous nephrolithotomy as well as complication rate.

title: Towards development and validation of an intraoperative assessment tool for robot-assisted radical prostatectomy training: results of a Delphi study

description: ABSTRACT Introduction As urology training shifts toward competency-based frameworks, the need for tools for high stakes assessment of trainees is crucial. Validated assessment metrics are lacking for many robot-assisted radical prostatectomy (RARP). As it is quickly becoming the gold standard for treatment of localized prostate cancer, the development and validation of a RARP assessment tool for training is timely. Materials and methods We recruited 13 expert RARP surgeons from the United States and Canada to serve as our Delphi panel. Using an initial inventory developed via a modified Delphi process with urology residents, fellows, and staff at our institution, panelists iteratively rated each step and sub-step on a 5-point Likert scale of agreement for inclusion in the final assessment tool. Qualitative feedback was elicited for each item to determine proper step placement, wording, and suggestions. Results Panelist’s responses were compiled and the inventory was edited through three iterations, after which 100% consensus was achieved. The initial inventory steps were decreased by 13% and a skip pattern was incorporated. The final RARP stepwise inventory was comprised of 13 critical steps with 52 sub-steps. There was no attrition throughout the Delphi process. Conclusions Our Delphi study resulted in a comprehensive inventory of intraoperative RARP steps with excellent consensus. This final inventory will be used to develop a valid and psychometrically sound intraoperative assessment tool for use during RARP training and evaluation, with the aim of increasing competency of all trainees.

title: Corneal backscatter in insulin-dependent and non-insulin-dependent diabetes mellitus patients: a pilot study

description: ABSTRACT Purpose: To compare central corneal backscatter obtained from Scheimpflug images between patients with insulin-dependent and non-insulin-dependent diabetes mellitus (IDDM and NIDDM, respectively) and healthy controls. Methods: Seven patients with IDDM (7 eyes), eleven patients with NIDDM (11 eyes), and sixteen healthy subjects (16 eyes) were included in this pilot study. Scheimpflug imaging system (Pentacam, Oculus Inc., Germany) was used to obtain optical sections of the cornea. Seven meridians were analyzed for each eye, oriented from 70° to 110°. Optical density values for the central 3-mm and 5-mm zones of the cornea were obtained by image analysis using external software. Results: Corneal backscatter was significantly higher in the diabetic patients than in the controls for the central 3-mm (p=0.016) and 5-mm (p=0.014) zones. No significant differences in corneal backscatter were found between the IDDM and NIDDM groups for either zone (both p&gt;0.05). In the NIDDM group, significant correlations were observed for both central zones between corneal backscatter and age (3 mm: r=0.604, p=0.025; 5 mm: r=0.614, p=0.022) and central corneal thickness (3 mm: r=0.641, p=0.017; 5 mm: r=0.671, p=0.012); this was not found in the IDDM group (p&gt;0.05). The presence of diabetes showed a significant effect on central corneal backscatter (Kruskal-Wallis test, p&lt;0.001). Conclusions: Diabetic patients showed higher values of corneal light backscatter than healthy subjects. Corneal optical density analysis may be a useful tool for monitoring and assessing the ocular changes caused by diabetes.

title: Effects of obesity on retrobulbar flow hemodynamics: color Doppler ultrasound evaluation

description: ABSTRACT Purpose: To evaluate intraocular pressure (IOP) and extraocular orbital vessels with color Doppler ultrasound (CDU) and investigate the effects of obesity on retrobulbar blood flow. Methods: Fifty-nine patients were included in this prospective study. Patients were divided into two groups according to body mass index: Group 1 (31 obese patients) and Group 2 (28 non-obese patients). IOP was measured with a Goldmann applanation tonometer, and CDU was used to evaluate the retrobulbar vessels. Results: The mean IOP was 18 ± 6.68 mmHg in the obese group and 13.71 ± 1.60 mmHg in the control group (p&lt;0.001). When the CDU values for the central retinal artery were compared between the groups, the pulsatility index was found to be significantly lower in the obese group than in the control group (p&lt;0.001). When the CDU values for the ophthalmic artery (OA) were compared between the groups, the peak systolic velocity (p&lt;0.001) and end-diastolic velocity (p=0.002) values were found to be significantly lower in the obese group than in the control group. Conclusions: Obese patients have a higher mean IOP and lower flow velocity than non-obese patients. Increased IOP together with decreased retrobulbar blood flow, particularly in obese individuals, may increase the risk of glaucoma development.

title: Strategy, People and Operations as influencing agents of the Project Management Office performance: an analysis through Structural Equation Modeling

description: Abstract The environment in which organizations operate is shown increasingly complex and competitive, leading companies to structure themselves in order to get quick, flexible and innovative responses. Projects are important instruments for promoting change and development. Since the 1990s, it’s been intensified in organizations the creation of the Projects Managements Offices, accepted by executive, which is the central point of support within the organization, so that work oriented by projects will be completed within the constraints of the business. The international research indicates the Project Management Office as a focus of interest, since the results found have not yet reached the answers needed to help professionals to solve their problems. This paper aims to evaluate the performance of the Project Management Office, from the constructs: “implementation strategies”, “capacitation and personnel training” and “control of the operations environment in projects”. The approach was a quantitative research in a single cross-sectional study and the conceptual model was examined with Structural Equation Modeling. The results indicate the degree of influence of constructs on Project Management Office performance, and people, is the most significant predictor, followed by strategies and finally operations.

title: Fuzzy Goal Programming applied to the process of capital budget in an economic environment under uncertainty

description: Abstract The Goal Programming (GP) is a multi-criteria approach of Operational Research that has been used for solving complex decision problems. This paper proposes a new Fuzzy Goal Programming (FGP) model to handle the process of capital budget of companies in an economic environment under uncertainty. For performance comparison purposes, the FGP and another recently published model developed for the same purposes were applied to data from a company that was the object of the study. The modeling and optimization were made with the GAMS software - 23.6.5 and using the CPLEX solver. The results obtained from the FGP model provided higher improvements than those obtained with the alternative model, as for example: increased profitability index, reduced payback and better application of the capital available in the budget. Furthermore, the FGP model has flexibility features that allow the manager to simulate, quickly and easily obtaining results about scenarios under uncertainty.

title: Safety programs for the feed industry: characterization and perceived benefits of the implementation

description: Abstract This article aimed to analyze the internal and external perceived benefits of the implementation of GMP and HACCP in factories of the feed industry, and the difficulties perceived during deployment. A survey research was conducted through a questionnaire which was sent to the companies. Sixty units responded the questionnaire. Descriptive statistics, correlation tests and clusters were applied for data analysis. The cluster analysis identified three groups of companies, which differed from each other mainly by their size and certification of food safety standards. While product quality is a general requirement of the sector, the understanding that the adoption of programs to guarantee food safety is important for the quality of feed provided to the animals and essential for the quality of food of animal origin (meat, milk, eggs) does not seem to be a unanimous perception of the industry, considering that 26.7% of the sample does not apply the HACCP yet and only 50.0% has some certification related to food safety. It was observed that the units that supply the most demanding markets tend to adopt these programs and their certification. The main internal benefits reported after the implementation of GMP/HACCP were reduction of food safety related problems and improvement of the level of training of production employees. As for external benefits, the most cited were improved brand image and customer satisfaction.
