Women with pelvic organ prolapse and fibulin-5 rs12589592 polymorphism
This study aims to access the frequency of single-nucleotide polymorphism rs12589592 (G>A) of the fibulin-5 gene in a Brazilian population with pelvic organ prolapse. This was a case-control study, with menopausal women divided into two groups and classified using the pelvic organ prolapse quantification system: pelvic organ prolapse group: pelvic organ prolapse quantification system stages III and IV and Control group: pelvic organ prolapse quantification system stages I and 0. We collected epidemiologic and baseline health information and performed genotyping of rs12589592 from the fibulin-5 gene using a restriction fragment length polymorphism (polymerase chain reaction-restriction fragment length polymorphism) strategy, based on the distinction of sequences from alleles G and A by the restriction enzyme DdeI. For the pelvic organ prolapse group and control, 111 and 180 women were recruited, respectively. The rs12589592 (G>A) polymorphism analysis showed 141 GG homozygotes (pelvic organ prolapse group: 53 [47.7%] and Control: 88 [49.2%] p=0.850); and 149 AA+GA: (pelvic organ prolapse group: 58 [52.3%]; Control: 91 [50.8%]; p=0.904). The distribution of genotypes did not follow the Hardy-Weinberg equilibrium conditions. There was no difference between groups regarding genotypes (rs12589592 G>A) frequency; however, the population characteristics prevent the analysis of the association between the genotype and the occurrence of prolapse.

Night eating syndrome among university students: are aspects of academic life associated with eating disorders?
Introduction: the critical period in the lives of college adults implies lifestyle changes such as reducing physical activity and adopting unhealthy eating habits that can result in increased body fat. Thus, college students may represent a population at increased risk for Night Eating Syndrome. Objective: to analyze aspects of university students’ academic life, work and housing that could be associated with Night Eating Syndrome. Methods: cross-sectional study carried out with 900 students from Architecture, Engineering, Medicine and Psychology courses at a higher education institution located in Cajazeiras, Paraíba, Brazil. Self-administered questionnaires were used for data collection: the Night Eating instrument Questionnaire (NEQ) to quantify Night Eating Syndrome (NES) behaviors and a form for variables on demographic, health, academic life, work and housing aspects. Results: the prevalence of NES determined by the NEQ≥25 score was 16.8%. In the Engineering course, the prevalence of NES was higher in women than in men, and in the Psychology course, it was higher in men than in women. Among students with a job and who lived at home, the prevalence of the syndrome was higher for those who worked in the afternoon and lower for those who worked at night. Conclusion: the prevalence of NES found among Brazilian university students was high (16.8%), particularly in two situations: (1) being enrolled in an undergraduate course with a predominance of students of the other sex; and (2) live with parents and work in the afternoon. These observations may be helpful in identifying subpopulations of students at increased risk for eating disorders.

Temporal trend of mortality and hospitalization for chronic kidney disease in adults from Northern Brazil
We aimed to evaluate mortality and hospital admissions for chronic kidney disease in young adults according to sex and state in the northern region of Brazil, between 1996 and 2017. A population-based time series study using official data on mortality and hospital admissions due to chronic kidney disease in individuals aged 20 to 49 years old, residents of the northern region of Brazil, in the periods 1996–2017 and to 2008–2017, respectively. Chronic kidney disease was defined according to the International Classification of Diseases, 10th revision (N18). The evolution of mortality from chronic kidney disease decreased by 0.881% per year over the period (1996–2017). In the states of Acre and Amapá, there was a reduction of 5.85% and –5.68% per year, respectively, and in Tocantins, an increase of 4.16% per year. The incidence of hospitalization did not vary between 2008 and 2017. However, 2 states showed an increase in hospitalization rates: Acre (6.08% per year) and Pará (2.83% per year), and 2 states showed a reduction: Amazonas (5.09% per year) and Tocantins (6.23% per year). In general, there was decrease in mortality rate overtime. However, rate of mortality due to chronic kidney disease increased in the state of Tocantins. The evolution of hospitalization due to chronic kidney disease in a population of young adults remained stationary.

The rs2165241 polymorphism of the Loxl1 gene in postmenopausal women with pelvic organ prolapse
This study aimed to verify the presence of polymorphism rs2165241 of the lysyl oxidase-like 1 (Loxl1) gene and its association with pelvic organ prolapse (POP) in Brazilian women and determine risk factors for POP development. The study was previously approved by the local research and ethics board. Postmenopausal women were included and divided into POP (stages III and IV) and control (stages 0 and I) groups. Peripheral blood samples were collected, and the DNA sequence of interest was analyzed by real-time reverse-transcriptase polymerase chain reaction. We used logistic regression and considered a recessive model of inheritance for the analysis, with p < 0.05 for significance. A total of 836 women were assessed: 426 POP cases and 410 controls. The frequencies of CC, CT and TT genotypes were similar in both groups. Age (odds ratio [OR] = 1.1, 95% confidence interval [CI] = 1.07; 1.14), number of vaginal births (OR = 17.06, 95% CI = 5.94; 48.97), family history (OR = 2.87, 95% CI = 1.57; 5.22) and weight of largest newborn (OR = 1.001, 95% CI = 1.0003; 1.001) were independent risk factors for POP, while multiple cesarean sections (two or more) was protective (OR = 0.17, 95% CI = 0.07; 0.42). No association was detected between rs2165241 of the Loxl1 gene and POP.

Medication non-adherence in patients with type 2 diabetes mellitus with full access to medicines
Purpose The pharmacological treatment for Type 2 diabetes mellitus (T2DM) is continuous and adherence to medication is critical for disease control. Restricted access to medicines is one of the most important barriers to adherence to T2DM treatment. This study aimed to evaluate other factors for medication non-adherence by studying patients with full access to oral hypoglycemic agents. Methods Cross-sectional study with 300 patients receiving their medication without costs from a referral center for diabetes care in Crato, Ceará (Brazil). Participants were recruited from January to December 2017. Information was obtained by self-applied questionnaires, and the drugs used were confirmed in the prescription. Adherence to medication was determined by the Morisky Medication Adherence Scale (MMAS-4). Patient perceptions of drugs were assessed by the Beliefs about Medicines Questionnaire (BMQ). Results Only 22.7% of participants met the criterion of high adherence to medication. The most frequent characteristics in the low adherence group were married; hypertension; no regular physical activity; therapy based on the combination of two or more oral antidiabetic agents without insulin; low score in the BMQ necessity scale. Necessity score in BMQ increased with age and the number of medications used and decreased if the patient had family members with the same disease and had children. Conclusions Full access to medicines did not assure high adherence to pharmacological treatment of type 2 diabetes mellitus. Distinctive factors to medication non-adherence may be found and specific barriers should be considered when planning actions for improving adherence in such populations.

Evaluation of the fibulin 5 gene polymorphism as a factor related to the occurrence of pelvic organ prolapse
SUMMARY OBJECTIVE Pelvic organ prolapse (POP) is a very frequent situation in our population that may lead to a significant decrease in patients’ quality of life. Currently, we are looking for predictive factors for the development of POPs; thus, this study seeks to evaluate whether the Fibulin 5 polymorphism (FBLN5) is associated with the occurrence of POP. METHODS This is a cohort study with postmenopausal women who were divided into groups by POP stage: POP stages 0 and I (control group) and POP stages III and IV (case group). Subsequently, analyses of genetic polymorphisms of FBLN5 were performed using the Restriction Fragment Length Polymorphism (RFLP) technique. RESULTS A total of 292 women were included in the study. Pregnancy, parity and vaginal delivery in the patients, as well as in data described in the literature, were related to the occurrence of POP in the univariate analysis. However, after binary logistic regression, home birth and age remained independent risk factors for POP. We found no association between the FBLN5 polymorphism and the occurrence of POP (p = 0.371). CONCLUSION There was no association between the FBLN5 polymorphism and the occurrence of POP in Brazilian women.

Association between col1a2 Polymorphism and the Occurrence of Pelvic Organ Prolapse in Brazilian Women
Objective To evaluate the rs42524 polymorphism of the procollagen type I alpha (α) 2 (COL1A2) gene as a factor related to the development of pelvic organ prolapse (POP) in Brazilian women. Methods The present study involved 112 women with POP stages III and IV (case group) and 180 women with POP stages zero and I (control group). Other clinical data were obtained by interviewing the patients about their medical history, and blood was also collected from the volunteers for the extraction of genomic DNA. The promoter region of the COL1A2 gene containing the rs42524 polymorphism was amplified, and the discrimination between the G and C variants was performed by digestion of the polymerase chain reaction (PCR) products with the MspA1I enzyme followed by agarose gel electrophoresis analysis. Results A total of 292 women were analyzed. In the case group, 71 had the G/G genotype, 33 had the G/C genotype, and 7 had the C/C genotype. In turn, the ratio in the control group was 117 G/G, 51 G/C, and 11 C/C. There were no significant differences between the groups. Conclusion Our data did not show an association between the COL1A2 polymorphism and the occurrence of POP.
