The effectiveness of mobile application for monitoring diabetes mellitus and hypertension in the adult and elderly population: systematic review and meta-analysis.

CONTEXT: Arterial Hypertension (AH) and Diabetes Mellitus (DM) are diseases that are getting worse all over the world. Linked to this advance, is the growing digital health market with numerous mobile health applications, which aim to help patients and professionals in the proper management of chronic diseases. The aim of this study was to analyze, through a systematic review and meta-analysis, the effectiveness of using mobile health applications in monitoring AH and/or DM in the adult and elderly population. METHODS: The systematic review and meta-analysis was carried out in accordance with the Preferred Reporting Items for Systematic Reviews and Metanalyses guidelines and involved searching five databases - Medline/PubMed, Embase, CINAHL, Virtual Library in Health and Cochrane Library. The review included randomized and cohort clinical trials testing the effects of the intervention on changing biochemical parameters and clinical efficacy in people treated for AH and/or DM. The quality of the selected studies was assessed based on the evaluation criteria of the Joanna Briggs Institute tool. The random effects meta-analysis method was used to explain effect distribution between studies, by Stata® software (version 11.0) and publication bias was examined by visual inspection of graphs and Egger test. RESULTS: We included 26 studies in the systematic review and 17 in the meta-analysis. These studies were published between 2014 to 2022 in 14 countries. Were reported improvement in knowledge and self-management of AH and DM, social motivation with treatment and behavioral change, reduction in glycated hemoglobin values, fasting glucose and blood pressure, improvement in adherence to drug treatment, among others. The result of the meta-analysis showed that there is evidence that the use of mobile applications can help reduce glycated hemoglobin by 0.39% compared to the usual care group. CONCLUSIONS: Monitoring and self-monitoring of behaviors and health care related to AH and DM in adults and the elderly through mobile applications, has clinically significant effectiveness in reducing glycated hemoglobin levels. Future studies should provide more evidence and recommendations for best practices and development of digital health interventions. TRIAL REGISTRATION: PROSPERO.

Low-grade albuminuria and its relationship with cardiovascular disease risk in hypertensive and diabetic patients in primary health care.

OBJECTIVE: To evaluate the presence of LGA and the relationship with the 10-year risk of a cardiovascular event in hypertensive and diabetic patients in Primary Health Care. STUDY DESIGN: The study design used is cross-sectional. METHODS: This study was based on the application of questionnaires, anthropometric measurements, and laboratory tests carried out from August 2017 to April 2018. Logistic regression was used to evaluate the odds ratio of the explanatory variables in relation to the highest tercile of LGA. The Framingham risk score was used to assess the 10-year risk of cardiovascular event. The comparison of this score with the LGA terciles was analyzed using ANOVA. RESULTS: An increase in the 10-year risk of cardiovascular event score was observed with an increasing LGA tercile, and this pattern prevailed after adjusting for confounding variables. CONCLUSION: An association between LGA and the 10-year risk of cardiovascular event was observed in a representative sample of hypertensive and diabetic patients.

Association of uric acid and uric acid to creatinine ratio with chronic kidney disease in hypertensive patients.

BACKGROUND: Recent studies have shown that the serum uric acid/creatinine ratio (SUA/SCr) is a better predictor of chronic kidney disease (CKD) than serum uric acid (SUA) isolated. The aim of the present study was to evaluate the association of isolated SUA and the SUA/SCr with CKD in hypertensive patients. METHODS: Cross-sectional study conducted with hypertensive patients followed-up by the Primary Health Care Service (PHC). Sociodemographic, economic, lifestyle, clinical, anthropometric, and biochemical variables were evaluated. The association between SUA parameters (quartiles of SUA and quartiles of SUA/SCr) and CKD was evaluated by bivariate and multivariate logistic regression. The association between SUA parameters (SUA and SUA/SCr) and estimated glomerular filtration rate (eGFR) was evaluated by linear regression. The analyses were performed considering four adjustment models. SUA and SUA/SCr were compared by receiver operating characteristic (ROC) curve. RESULTS: In the fully adjusted model, SUA was positively associated with the presence of CKD (OR = 6.72 [95 % CI 1.96-22.96]) and inversely associated with eGFR (ß Coef. = -2.41 [95 % CI -3.44; -1.39]). SUA/SCr was positively associated with eGFR (ß Coef. = 2.39 [1.42; 3.36]). According to the ROC curve, the SUA is a better predictor of CKD than the SUA/SCr. CONCLUSIONS: Elevated levels of isolated SUA were associated with CKD and eGFR. However, the SUA/SCr was not associated with CKD. We do not recommend using the SUA/SCr to predict CKD in hypertensive patients.

Survival and analysis of predictors of mortality in patients undergoing replacement renal therapy: a 20-year cohort.

BACKGROUND: optimal management of end-stage renal disease (ESRD) in hemodialysis (HD) patients should be more studied because it is a serious risk factor for mortality, being considered an unquestionable global priority. METHODS: we performed a retrospective cohort study from the Nephrology Service in Brazil evaluating the survival of patients with ESRD in HD during 20 years. Kaplan-Meier method with the Log-Rank and Cox's proportional hazards model explored the association between survival time and demographic factors, quality of treatment and laboratory values. RESULTS: Data from 422 patients were included. The mean survival time was 6.79 ± 0.37. The overall survival rates at first year was 82,3%. The survival time correlated significantly with clinical prognostic factors. Prognostic analyses with the Cox proportional hazards regression model and Kaplan-Meier survival curves further identified that leukocyte count (HR = 2.665, 95% CI: 1.39-5.12), serum iron (HR = 8.396, 95% CI: 2.02-34.96), serum calcium (HR = 4.102, 95% CI: 1.35-12.46) and serum protein (HR = 4.630, 95% CI: 2.07-10.34) as an independent risk factor for the prognosis of survival time, while patients with chronic obstructive pyelonephritis (HR = 0.085, 95% CI: 0.01-0.74), high ferritin values (HR = 0.392, 95% CI: 0.19-0.80), serum phosphorus (HR = 0.290, 95% CI: 0.19-0.61) and serum albumin (HR = 0.230, 95% CI: 0.10-0.54) were less risk to die. CONCLUSION: survival remains low in the early years of ESRD treatment. The present study identified that elevated values of ferritin, serum calcium, phosphorus, albumin, leukocyte, serum protein and serum iron values as a useful prognostic factor for the survival time.

[The positive deviance approach to change nutrition behavior: a systematic review]. / Abordagem do desvio positivo para a mudança de comportamento alimentar: revisão sistemática.

OBJECTIVE: To conduct a systematic review of the literature describing the use of the positive deviance approach to change nutrition behavior in order to identify the potentials of this method for health and nutrition education. METHODS: Cochrane Library, LILACS, MEDLINE, SciELO, PubMed, and Scopus were searched. The following search terms were used: positive deviance, desvio positivo, positive deviance inquiry and positive deviants. Inclusion criteria were: reporting primary data, clearly defined methods, and availability of full text. The main results of the studies selected for inclusion were described and examined based on psychosocial (socioeconomic and health status, hygiene and nutrition habits), anthropometric (weight, height), and biochemical and clinical (presence of morbidity and biochemical tests) criteria to determine the potential and limitations of the positive deviance approach to change nutrition behavior. RESULTS: Of the 47 studies identified, nine met the inclusion criteria. The positive deviance method was used for prevention and rehabilitation of child and maternal malnutrition in areas of socioeconomic vulnerability and for the treatment of overweight and obesity in adults. An improvement in maternal and child nutrition and the maintenance of beneficial behaviors over time were underscored as positive impacts of the method. CONCLUSIONS: The positive deviance approach may help change nutrition behaviors with the aim of reversing child malnutrition and overweight and obesity in adults. This approach seems effective to promote health education in areas of socioeconomic vulnerability.

[The Bolsa Família cash transfer program and food and nutrition security in Brazil: a critical review of the literature]. / Programa Bolsa Família e segurança alimentar e nutricional no Brasil: revisão crítica da literatura.

OBJECTIVE: To critically review studies evaluating the impact of Bolsa Família (PBF), a federal cash transfer program, for food and nutrition security in Brazil. METHODS: The Cochrane Library, LILACS, Medline and SciELO databases were searched, as well as public organization websites. All studies based on primary data were selected. The following were excluded: studies using secondary data, review articles, studies that did now allow the establishment of associations between PBF and food and nutrition security, as well as studies evaluating food security strictly in sanitary terms. RESULTS: Ten studies were included. Of these, five concluded that PBF had a positive impact on the food and nutrition security of participating families. Three studies observed an increase in the consumption of foods with higher calorie content and less nutritional value. This change in dietary habits is a risk factor for the development of overweight, obesity, and noncommunicable chronic diseases. CONCLUSIONS: The guarantee of food and nutrition security requires programs that focus on both malnutrition and overweight and obesity. Cash transfer programs such as the PBF can contribute more effectively to the nutritional well-being of participants if they are combined with other types of interventions, such as actions to promote healthy eating.

[Health promotion and primary prevention strategies to fight chronic disease: a systematic review]. / Estratégias de promoção da saúde e prevenção primária para enfrentamento das doenças crônicas: revisão sistemática.

OBJECTIVE: To analyze health promotion and primary prevention strategies in the global fight against chronic noncommunicable diseases (NCDs) and to reflect on the challenges of overcoming these diseases. METHODS: In this systematic literature review, studies were analyzed on health programs identified by the Brazilian Health Ministry as the main global community intervention initiatives: the North Karelia Project, in Finland; the Stanford Three-Community Study, Stanford Five-City Project, Minnesota Heart Health and Pawtucket Heart Health Program, in the United States; the CINDI project, in Europe and Canada; CARMEN in South America; Mirame, in Chile; and Tianjin, in China. The LILACS, Medline, and SciELO databases were searched, as well as the Brazilian Health Ministry, Pan American Health Organization, and World Health Organization websites. Only original articles analyzing primary data were included. The outcomes evaluated in the studies were cholesterol, blood pressure, obesity, physical activity level, tobacco use, dietary habits, and other risk factors for NCDs. RESULTS: Seventeen studies were selected. The North Karelia Project, Three Community Study, and Five-City Multifactor Risk Reduction Project contributed to decrease tobacco use, cholesterol levels, and blood pressure levels. The Minnesota Heart Health Program and the Pawtucket Heart Health Program had moderate success in reducing the risk factors for NCD. The CINDI and CARMEN programs demonstrated the importance of integrated actions for decreasing the main risk factors. The Mirame project, which focused on educational interventions for school children, reached 30,000 students in 2001 without requiring a large financial investment. The Tianjin project was able to reduce salt intake, prevalence of arterial hypertension, and obesity by restructuring primary health care services. CONCLUSIONS: These successful experiences in community health improvement may serve as models for the implementation of more effective health policies, aiming at the development of actions that integrate health promotion and primary prevention of the main risk factors for NCDs.

Prevalence of Excessive Iodine Intake in Pregnancy and Its Health Consequences: Systematic Review and Meta-analysis.

The objective was to estimate the prevalence of excessive iodine intake in pregnant women and to investigate the consequences for maternal-fetal health. The systematic review was based on PRISMA. The search was conducted in September 2021 in LILACS, PubMed/MEDLINE, Science Direct, and SCOPUS databases. Observational studies that assessed excessive nutritional iodine status in pregnancy diagnosed by urinary iodine concentration and associated it with biomarkers of thyroid health function were included. Study selection, data extraction, and risk of biased evaluation were performed independently. Meta-analysis was calculated using a fixed and random effect model, and heterogeneity was assessed by the chi-square test. Meta-regressions were performed to identify the causes of heterogeneity using the Knapp and Hartung test. Nine studies were included in the systematic review, and eight in the meta-analysis. The prevalence of excessive iodine intake in 10,736 pregnant women in different regions of the world was 52%. The main implications for pregnant women were hypothyroxinemia, hypothyroidism, and hyperthyroidism. For the newborn, macrosomia and thyroid dysfunction. In addition, drinking water with high iodine intake contributed to excessive iodine intake. Therefore, the prevalence of iodine excess was 52%, with high heterogeneity among studies, explained by trimester of gestation and FT4 level; therefore, the farther the trimester of gestation and the lower the FT4, the higher the prevalence of iodine excess.

The effectiveness of the use of telehealth programs in the care of individuals with hypertension and, or diabetes mellitus: systematic review and meta-analysis.

INTRODUCTION: Diabetes Mellitus and Hypertension are some of the main Chronic Noncommunicable Diseases, representing a big challenge for global health. In this context, Telehealth programs are presented as a tool with exciting potential to complement and support health care. This paper aimed to analyze the effectiveness of the use of Telehealth programs in the care of individuals with Hypertension and/or Diabetes Mellitus. METHODS: A systematic review with meta-analysis was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol methodology. The following databases were used: PubMed, EMBASE, SciELO, ScienceDirect and Cochrane Library. Papers were included if they addressed the use of technologies that allow two-way communication at a distance between health professionals and patients affected by Hypertension and/or Diabetes Mellitus, type 1 or type 2. Experimental, cross-sectional, case-control, cohort, and clinical trials were included in the review. RESULTS: We included 164 papers in the review and 45 in the meta-analysis final synthesis. The systematic review results showed a prevalence of telemonitoring as the main form of Telehealth. The study showed a reduction in expenses with the use of Telehealth, both for the users and for the health systems providers, followed by greater satisfaction. Our meta-analysis showed that Telehealth is an effective tool in the care of diabetic patients, providing a 0.353% reduction in HbA1c compared to traditional care. No studies on Hypertension that met our eligibility criteria for inclusion in the meta-analysis were found. CONCLUSIONS: Telehealth is an effective tool for the care of people with Diabetes Mellitus and/or Hypertension.

[Learning portfolios as a tool for reflection: building competencies for work in the Unified Health System]. / Portfólios reflexivos: construindo competências para o trabalho no Sistema Único de Saúde.

OBJECTIVE: To assess the innovative experience of competency education through reflective portfolios for the training of professionals who will work in the Brazilian Unified Health System (SUS). METHODS: A qualitative research approach was employed. Documentary analysis was carried out covering 25 portfolios produced in the years 2008, 2009, and 2010 in the health policy course at the Federal University of Viçosa, Minas Gerais, Brazil, in order to verify if this method allowed the acquisition of the competencies: learning to be (acting with autonomy, good judgment, personal responsibility); learning to know (assimilating general and specific scientific and cultural knowledge, which will be complemented and updated in the course of life); learning to do (acquiring procedures that will be useful for facing life and work difficulties); and learning to live and work together (better understanding of others, the world, and their inter-relationships). RESULTS: Students became involved with the proposed activities, especially the management of information (active search, selection, critical analyses, reviews, syntheses, and evaluation of information). There was a gradual opening to critical thinking, integrating new dimensions to the initial vision held by students on the SUS, which moved from a focus on disease and healing to a focus on health and prevention, and from a vision of SUS as a theoretical model towards a view of SUS as a feasible project that is under construction. CONCLUSIONS: The use of portfolios has enabled the education of citizen-health professionals, with academic, pedagogical, and practical emphasis. This indicates that universities and teachers can turn to the development of decision-making capacities and reflective thinking by students.

[Evidence of the contribution of elderly support programs to healthy aging in Brazil]. / Evidências da contribuição dos programas de assistência ao idoso na promoção do envelhecimento saudável no Brasil.

OBJECTIVE: To search the literature for evidence of the contribution of elderly health programs to the process of healthy aging in Brazil. METHODS: The databases Science Direct, SciELO, LILACS, IBECS, the Cochrane Library, and MEDLINE were searched to find articles focusing on initiatives developed for the elderly population and to promote healthy aging, providing a multidimensional evaluation of the quality of life of the elderly, and covering aspects relating to specific health promotion practices. The initiatives were considered effective if the following criteria were met: having goals that included the improvement of health and well-being, having a focus on holistic health, using empowerment as a central mechanism to improve health, and meeting the prerequisites for health and developing actions in the priority areas described in the Ottawa Charter. RESULTS: Ten articles referring to five elderly health promotion programs in Brazil were identified. All the programs met the efficacy criteria, and included elements that promoted healthy aging through characteristics that fostered the insertion of the elderly in society through the creation of a support environment for the prevention of injury, increase in functional capacity, and improvement of quality of life. CONCLUSIONS: Studies are required to produce scientific evidence on the efficacy, efficiency, and effectiveness of elderly health programs to determine the value of these actions to promote healthy aging.

Perception of the Food and Nutrition Surveillance System in the Zona da Mata Mineira region of Brazil: A qualitative approach.

This work is a qualitative exploratory survey that aims to identify healthcare workers and skilled professionals' perceptions of the Food and Nutrition Surveillance System in the Zona da Mata Mineira region of Brazil. Data analysis was carried out through content analysis; testimonials were extracted from semi-structured interviews via the qualitative data processing software Interface de R pour lês Analyses Multidimensionnelles de Textes et de Questionnaires version 0.7 alpha 2. A total of 41 people were interviewed, including primary healthcare center coordinators, and technical consultants at the Food and Nutrition Surveillance System, as well as nutritionists and data entry clerks. The issues most mentioned during interviews were related to lack of anthropometric equipment, absence of transportation, and inadequate facilities. Regarding the work process, professionals identified scarce training and nonuse of the data collected for healthcare decision-making as factors that compromise desired system outcomes. System qualities were also recognized, especially the mapping of main nutritional issues in the region. The participants reported the need for greater efforts to raise awareness of the importance of Food and Nutrition Surveillance actions at all levels of the public healthcare system. They also highlighted the need for human resources training, higher quality data recording, and suitable facilities. Investments in the entire system are essential to strengthen the information-decision-making-action triad, which would result in the improvement of users' health indicators.

Data quality and arbovirus infection associated factors in pregnant and non-pregnant women of childbearing age in Brazil: A surveillance database analysis.

The dengue surveillance system in Brazil has registered changes in the disease's morbidity and mortality profile over successive epidemics. Vulnerable groups, such as pregnant women, have been particularly hard hit. This study assessed the quality of notifications of dengue cases among pregnant women and non-pregnant women of childbearing age in Brazil, in addition to discussing the factors associated with arbovirus infection in the group of pregnant women. We carried out a retrospective study of cases registered in the national arbovirus surveillance system between 2007 and 2017. The indicator for assessing quality was incompleteness. Logistic regression was used to analyze the association between dengue during pregnancy and sociodemographic, epidemiological, clinical, and laboratory variables. The incompleteness of the data in the notification form for dengue cases in women of childbearing age and pregnant women indicates a significant loss of information. Dengue was shown to be positively associated with Social Determinants of Health in both groups, with more severe effects among pregnant women. The incompleteness of the data can limit the quality of information from the notification system and the national assessment of the situation of the disease in women of childbearing age and pregnant women.

Hypertriglyceridemic waist phenotype and associated factors in individuals with arterial hypertension and/or diabetes mellitus.

Cardiovascular diseases are among the main causes of death in Brazil and worldwide. The literature indicates the hypertriglyceridemic waist phenotype (HTWP) as an accessible alternative for the identification of cardiovascular and metabolic risk. The present study aimed to identify the prevalence and factors associated with HTWP in individuals diagnosed with arterial hypertension (AH) and/or diabetes mellitus type 2 (DM2). A cross-sectional study was conducted with individuals diagnosed with AH and/or DM2. The study data were collected through semi-structured interviews containing socio-demographic information, lifestyle, health care, in addition to anthropometric assessment, blood pressure measurement and biochemical blood tests. The prevalence of HTWP was estimated and bivariate and multivariate logistic regression was used to assess the factors associated with HTWP. Of the 788 individuals analysed, 21⋅5 % had the HTWP. In the adjusted model, the following variables remained associated with a greater chance of presenting HTWP: sex, age, body mass index (BMI) and very-low-density lipoprotein (VLDL). Being female increased the chance of HTWP by 7⋅7 times (OR 7⋅7; 95 % CI 3⋅9, 15⋅2). The one-year increase in age increased the chance of HTWP by 4 % (OR 1⋅04; 95 % CI 1⋅02, 1⋅06). The addition of 1 mg/dl of VLDL-c increased the chance of HTWP by 15 % (odds ratio (OR) 1⋅15; 95 % confidence interval (CI) 1⋅12, 1⋅18), as well as the increase of 1 kg/m2 in the BMI increased the chance of this condition by 20 % (OR 1⋅20; 95 % CI 1⋅15, 1⋅27). The prevalence of HTWP was associated with females, older age, higher BMI, higher VLDL-c and risk waist/height ratio.

Low-grade albuminuria in adult and elderly individuals with diabetes mellitus and arterial hypertension accompanied by Primary Health Care.

Diabetes mellitus (DM) and arterial hypertension (AH) are the two main clinical conditions related to Chronic Kidney Disease (CKD); disease also identify by the levels of low-grade albuminuria (LGA). Few studies have simultaneously investigated the associations of glycated hemoglobin (HbA1c) and fasting plasma glucose (FPG) with LGA. Our study aimed to investigate and compare the association of HbA1c and FPG with the probability of LGA in adult and elderly individuals with DM and AH, within the scope of Primary Health Care (PHC). Cross-sectional study involving 737 Brazilians individuals previously diagnosed with hypertension and/or diabetes. Tests for HbA1c, FPG and LGA were performed. LGA was defined as the highest quartile of albumin urinary (≥ 13 mg/g) among individuals with urinary LGA < 30 mg / g. A significant increase in the prevalence of LGA was found with increasing levels of HbA1c (p < 0.001). There was a significant association of HbA1c with LGA (p < 0.001) and increased probability of LGA for participants with HbA1c ≥ 6.5% compared to those with Hba1c < 5.7% (OR [95% CI]: 2.43 [1.32-4.46], p < 0.05), after adjusting for confounding factors, except when adjusted for FPG (p = 0.379 and p = 0.359, respectively). HbA1c and FPG were significantly associated in a collinear manner with an increased probability of LGA in adult and elderly individuals with DM and AH.

Nutritional status coverage trend registered in the SISVAN web in seven municipalities of the Zona Da Mata Mineira, Brazil, from 2008 to 2017, and its association with socio-economic, demographic and organisation of health system variables.

We analysed the coverage trend of the evaluation of the nutritional status of users of public health services registered in the Food and Nutrition Surveillance System (SISVAN) between 2008 and 2017 in seven municipalities and verified the association of the coverage trend with the socio-economic, demographic and organisational aspects of health system variables. It is an ecological time-series study performed with secondary data extracted from health information systems. Descriptive statistics, linear regression model and repeated measures analysis were performed. The coverage of evaluation of nutritional status was low over the period. Five municipalities showed a tendency to increase coverage, although small, while two remained stable. The highest annual variation in coverage increase was concentrated in the group of pregnant women and the lowest in adolescents and older adults. There was a downward trend in follow-ups from the Bolsa Family Programme and a trend towards increased follow-ups from SUS Primary Care (e-SUS AB). SISVAN coverage was positively associated with the proportion of rural population (P ≤ 0·001) and coverage of community health agents (P < 0·001); and negatively associated with total population (P < 0·001), demographic density (P = 0·006) and gross domestic product per capita (P = 0·008). Despite the tendency to increase coverage in some municipalities, SISVAN still presents low coverage of nutritional status assessment, which compromises population monitoring. Knowing the factors that influence the coverage can subsidise the elaboration of strategies for its expansion.

Computing and Oral Health: Mobile Solution for Collecting, Data Analysis, Managing and Reproducing Epidemiological Research in Population Groups.

Epidemiological inquiries study and evaluate the health status of the population. For dental caries, the World Health Organization (WHO) recommends the DMFT and DMFS indexes, which represent the sum of the decayed, missing and filled teeth, divided by the population studied. Traditionally these surveys are conducted using cellulose paper sheet. This study describes the development and presents the field performance of NutriOdonto, a software created for an Oral Health Survey carried out in 2018 and 2019 involving 2578 students from the municipal schools of Palmas/TO, located in the Brazilian Amazon region. This is a descriptive, applied research on the development of a software for the collecting, analysis, management and reproducibility of oral health epidemiological research. A software applied to the collecting, analysis and formation of the database was developed through the information obtained from the questionnaires applied to the participants of the study and the completion of the electronic oral examination form. Recent Information and Communication Technologies (ICT) are intelligently configured to create models and mobile applications (Apps) that can be useful to manage health issues, thus broadening the perspective of service provision in this sector. Some of these mobile devices, tablets and smartphones are being developed to generate information, for collection, recording, storage and analysis of oral health epidemiological research data. NutriOdonto contributed to the rapid collection, recording and storage of information, in the construction of the database and its analysis. Replacing paper forms with electronic forms minimized possible typos, reduced the use of cellulose paper and the financial costs, among other things. This software can contribute to decision making by managers and professionals and to improving the planning and implementation of actions in health promotion and oral disease prevention.

Prevalence of chronic kidney disease in Brazilians with arterial hypertension and/or diabetes mellitus.

The present study aimed to evaluate the prevalence of chronic kidney disease (CKD) in individuals with arterial hypertension (AH) and/or diabetes mellitus (DM) accompanied by Primary Health Care (PHC) in Brazil. The estimated glomerular filtration rate (eGFR) based on creatinine, and urinary albumin-to-creatinine ratio (ACR) were measured in 841 subjects with AH and/or DM, followed by PHC in the city of Viçosa. The CKD was diagnosed according to KDIGO criteria. Sociodemographic, clinical, and anthropometric factors related to the prevalence of CKD were investigated through multiple logistic regression. The prevalence of hidden CKD was 15.4%. Of these, 7.5% were identified by albuminuria (ACR ≥30 mg/g) with slightly decreased eGFR. Age, baseline disease, waist circumference (WC), and systolic blood pressure remained associated with CKD after multivariate analysis. The two major risk factors for hidden CKD were the presence of AH in association with DM and an increase in age. Hidden CKD was more common within people with AH and DM, and with high WC, glycosylated hemoglobin, and serum phosphorus as well as male gender and decreased serum albumin. This knowledge of risk associations can help avoid progression to CKD.

[Social representations of women who breastfeed about breast feeding and the use of pacifiers]. / Representações sociais de mulheres que amamentam sobre a amamentação e o uso de chupeta.

The objective was to identify the different meanings that surround the breastfeeding and the use of pacifiers of a group of mothers of children under six months old. Adopted to the precepts of qualitative research methodology. Interviews were conducted semi-structured individual, transcribed in full and analyzed using the technique to analyse the content of Bardin. The comprehensive analysis of speeches revealed the presence of representations which can carry interference in the decision to breastfeed - both positive, as negatively. In that sense, it is important that health professionals, know the context in which these women are found, especially their doubts, fears, myths and beliefs in relation to breastfeeding, thus acting in favour of lactation.

[Family health: challenges in the reorientation process of the assistance model]. / Saúde da família: desafios no processo de reorientação do modelo assistencial.

The Family Health Program (PSF) constitutes a strategy for reformulating the health assistance model in Brazil. This study was carried out to ponder over the challenges of this strategy concerning to health practices in the primary care context. After existing for more than twelve years, there appear questionings related to the paper of PSF in the reformulation of the way to think and promote health, and their structures remain permeable to the traditional hegemonic model that corrupts the daily work process. Some changes and reconstruction are necessary in the health practices concerning to care production based on light, relational and integrate technologies that are centered on users' needs. Although the deconstruction/reconstruction process implicates much labor, the advantage in overcoming the challenges faced by PSF rather leads to the transformation of reality and to construction of health practices that are solidary, welcoming, and resolvent.
