Díaz-Apodaca,Beatriz A.; Ebrahim,Shah; McCormack,Valerie; de Cosío,Federico G.; Ruiz-Holguín,Rosalba;
Revista Panamericana de Salud Pública , 2010, DOI: 10.1590/S1020-49892010000900007
Abstract: objetive: to estimate prevalence of type 2 diabetes (diabetes) and impaired fasting glucose (ifg) in the border region between the united states of america and mexico, by ethnic origin and country of residence; identify risk factors associated with both conditions; and explore the extent to which these factors account for cross-border or ethnic disparities in prevalence. methods: from april 2001 to november 2002, phase i of the u.s.-mexico border diabetes prevention and control project, a prevalence study of diabetes and its risk factors, was conducted at the u.s.-mexico border using multistage cluster sampling. a questionnaire was administered on diabetes (self-reported) and lifestyle and a physical examination and blood sample were obtained. a total of 4 027 adults participated in the study: 2 120 hispanics from the mexican side of the border and 1 437 hispanics and 470 non-hispanics (of whom 385 were classified as "white") from the u.s. side of the border. results: the age-adjusted prevalence of self-reported and unrecognized diabetes in hispanics was 15.4% (16.6% on the mexican side of the border and 14.7% on the u.s. side). the age-adjusted prevalence of ifg was similar on both sides of the border (14.1% on the mexican side and 13.6% on the u.s. side). conclusions: established risk factors for diabetes (e.g., age, obesity, and family history) were relevant and there was an inverse relationship between diabetes and education and socioeconomic level. while diabetes prevalence is high on both sides of the u.s.-mexico border, one-fourth of the cases remain undiagnosed, suggesting a need for development and implementation of a public health program for prevention, diagnosis, and control of diabetes in the region.

Revista Panamericana de Salud Pública , 2010, DOI: 10.1590/S1020-49892010000900011
Abstract: objective: to assess and monitor the quality of care provided to hispanics diagnosed with diabetes living in the border region between the united states of america and mexico. methods: from april 2001 to november 2002, phase i of the u.s.-mexico border diabetes prevention and control project, a prevalence study of type 2 diabetes and its risk factors, was conducted along the u.s.-mexico border using two-stage cluster sampling of towns and households within towns. a questionnaire was administered on diabetes (self-reported) and lifestyle and a physical examination and blood sample were obtained. of the 4 027 study participants, 521 (13.0%) reported receiving a pre-study diagnosis of diabetes. of those, 466 were of hispanic origin (226 on the mexican side of the border and 240 on the u.s. side). results: results indicated 42.1% of hispanics on the u.s. side of the border (95% confidence interval [ci] 35.8%-48.6%) and 37.6% of hispanics on the mexican side (95% ci 31.3%-44.3%) had controlled diabetes (defined as glycosylated hemoglobin a1c < 7.0 %), and only one (on the mexican side of the border) received optimal diabetes care, defined according to international criteria for systolic blood pressure and body mass index as well as health provider provision of yearly examinations of foot and eyes as preventive care measures for early detection of diabetes complications. conclusions: adult hispanics diagnosed with diabetes and living on the u.s.-mexico border region are not receiving adequate diabetes-related care, and health care professionals are not following international recommendations for providing that care. to improve diabetes control in the region, health care providers must become more aware of the effect of education and culture on diabetes self-care as well as the provision of preventative measures by health care professionals.
United States-Mexico border diabetes prevalence survey: lessons learned from implementation of the project
Cosío,Federico G. de; Díaz-Apodaca,Beatriz A.; Ruiz-Holguín,Rosalba; Lara,Agustín; Castillo-Salgado,Carlos;
Revista Panamericana de Salud Pública , 2010, DOI: 10.1590/S1020-49892010000900004
Abstract: this paper reviews and discusses the main procedures and policies that need to be followed when designing and implementing a binational survey such as the united states of america (u.s.)-mexico border diabetes prevalence study that took place between 2001 and 2002. the main objective of the survey was to determine the prevalence of diabetes in the population 18 years of age or older along u.s.-mexico border counties and municipalities. several political, administrative, financial, legal, and cultural issues were identified as critical factors that need to be considered when developing and implementing similar binational projects. the lack of understanding of public health practices, implementation of existing policies, legislation, and management procedures in mexico and the united states may delay or cancel binational research, affecting the working relation of both countries. many challenges were identified: multiagency/multifunding, ethical/budget clearances, project management, administrative procedures, laboratory procedures, cultural issues, and project communications. binational projects are complex; they require coordination between agencies and institutions at federal, state, and local levels and between countries and need a political, administrative, bureaucratic, cultural, and language balance. binational agencies and staff should coordinate these projects for successful implementation.

Cadernos de Saúde Pública , 2005,
Abstract: Three different school-based sex education and citizenship programs in public schools in Rio de Janeiro, Belo Horizonte, and Salvador, Brazil, were evaluated in a cross-sectional study comparing knowledge, attitudes, and practices in sexuality, citizenship, and gender issues among adolescents participating in the programs' activities as compared to adolescents enrolled in schools without such programs (controls). Results showed that Salvador's program achieved good results, with significant changes in knowledge on sexuality and reproductive physiology, attitudes regarding citizenship, and current use of modern contraceptives; Rio de Janeiro's program succeeded in improving students' knowledge of reproductive physiology and attitudes towards sexuality; Belo Horizonte's participants showed greater knowledge of reproductive physiology and STI/HIV prevention but had less positive attitudes towards gender issues, while reporting greater sexual activity. The main difference between Salvador's program and the others was the focus on creative and cultural activities; Belo Horizonte's main difference was its lack of interaction with health services and professionals. However, after the evaluation Belo Horizonte reframed its educational strategies and launched a scaling-up process in a joint effort with the health and school systems.

Abstract: Enterococcus faecalis is an important pathogen associated with endodontic diseases, and its elimination and control are of paramount importance, as it represents one of the major causes of failure in the treatment of endodontic disease. Twenty-five plant extracts obtained from Brazilian forests were found to be effective against planktonic E. faecalis and were subjected to two traditional antibacterial assays, the microdilution broth assay (MDBA) and the disk diffusion assay (DDA), using chlorhexidine (CHX) as a control. Seven out of 25 extracts showed significant antibacterial activity and were tested in a biofilm assay, and three of these extracts were subjected to chemical fractionation. Residues were tested for their antibacterial activity, and the first chemical findings were described based on thin layer chromatography (TLC). Extracts obtained from Ipomoea alba, Symphonia globulifera and Moronobea coccinea showed significant bactericidal activity in the MDBA. The same I. alba and S. globulifera extracts, as well as the extract obtained from Connarus ruber var. ruber, showed significant activity in the DDA. RH2O obtained from Psidium densicomum and Stryphnodendron pulcherrimum showed better antibacterial activity compared to the respective crude extracts and CHX. TLC analysis showed that phenolic compounds and triterpenes represent the first findings of chemical groups that may occur in all species. The results of the present study include the discovery of six active extracts against planktonic E. faecalis and support further testing via assays involving biofilm formation, as well as the determination of the compounds' chemical profiles, as their activity was significantly better than that observed for CHX.
