The chronic care model for type 2 diabetes: a systematic review

Abstract The chronic care model (CCM) uses a systematic approach to restructure health care systems. The aim of this systematic review was to examine studies that evaluated different elements of the CCM in patients with type 2 diabetes mellitus (T2DM) and to assess the influence of the CCM on different clinical outcomes. There view was performed in the Medline and Cochrane Library electronic databases. The search was limited to randomized controlled trials conducted with T2DM patients. Studies were eligible for inclusion if they compared usual care with interventions that use done or more elements of the CCM and assessed the impact on clinical outcomes. After applying the eligibility criteria, 12 studies were included for data extraction. Of these, six showed evidence of effectiveness of the CCM for T2DM management in primary care as well as significant improvements in clinical outcomes. In the other six studies, no improvements regarding clinical outcomes were observed when comparing the intervention and control groups. Some limitations, such as a short follow-up period and a low number of patients, were observed. Some studies showed that the reorganization of health systems can improveT2DM care. However, it is possible that greater benefits could be obtained through combing all 6 elements of CCM.

Evaluation of food intake and excretion of metabolites in nephrolithiasis

INTRODUCTION Nephrolithiasis is a common condition with high prevalence and recurrence, occurring by a complex and multifactorial process. OBJECTIVE To analyze the main dietary and metabolic characteristics of patients with nephrolithiasis and compare them with a control group. METHODS A cross sectional study with 31 patients with nephrolithiasis (NE) and 18 healthy. By the dietary intake it were observed sodium, calcium, protein, potassium, vitamin C, oxalate and water intake in both groups. Metabolic assessment were analyzed in urinary excretion of oxalate and citrate. The presence of hypertension and body mass index (BMI) was also evaluated. RESULTS In the NE group, it was found that 45.2% had a high intake of sodium and 100% a high intake of oxalate. It was also observed a low calcium, potassium and vitamin C intake by 93.5%, 100% and 94.9% respectively. Regarding protein, only 12.5% had normal protein intake. Concerning water intake, 12.9% had an ingestion less than 1 liter, 54.8% between 1 and 2 liters and 32.3% higher than 2 liters. Hypertension was observed in 64.5% of patients and adequate excretion of oxalate and citrate in 90.5% of them. There was no statistically difference in food intake, BMI and oxalate excretion between groups. However, the NE group showed higher urinary citrate. CONCLUSION It was found in both groups a high prevalence of overweight patients, a high intake of oxalate and sodium, in addition to inadequate intakes of calcium, potassium and vitamin C. The NE group showed high protein intake and increased excretion of citrate.

Predominant learning styles among pharmacy students at the Federal University of Paraná, Brazil

Background: Learning styles are cognitive, emotional, and physiological traits, as well as indicators of how learners perceive, interact, and respond to their learning environments. According to Honey-Mumford, learning styles are classified as active, reflexive, theoretical, and pragmatic. Objective: The purpose of this study was to identify the predominant learning styles among pharmacy students at the Federal University of Paraná, Brazil. Methods: An observational, cross-sectional, and descriptive study was conducted using the Honey-Alonso Learning Style Questionnaire. Students in the Bachelor of Pharmacy program were invited to participate in this study. The questionnaire comprised 80 randomized questions, 20 for each of the four learning styles. The maximum possible score was 20 points for each learning style, and cumulative scores indicated the predominant learning styles among the participants. Honey-Mumford (1986) proposed five preference levels for each style (very low, low, moderate, high, and very high), called a general interpretation scale, to avoid student identification with one learning style and ignoring the characteristics of the other styles. Statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS) version 20.0. Results: This study included 297 students (70% of all pharmacy students at the time) with a median age of 21 years old. Women comprised 77.1% of participants. The predominant style among pharmacy students at the Federal University of Paraná was the pragmatist, with a median of 14 (high preference). The pragmatist style prevails in people who are able to discover techniques related to their daily learning because such people are curious to discover new strategies and attempt to verify whether the strategies are efficient and valid. Because these people are direct and objective in their actions, pragmatists prefer to focus on practical issues that are validated and on problem situations. There was no statistically significant difference between genders with regard to learning styles. Conclusion: The pragmatist style is the prevailing style among pharmacy students at the Federal University of Paraná. Although students may have a learning preference that preference is not the only manner in which students can learn, neither their preference is the only manner in which students can be taught. Awareness of students’ learning styles can be used to adapt the methodology used by teachers to render the teaching-learning process effective and long lasting. The content taught to students should be presented in different manners because varying teaching methods can develop learning skills in students.

Alimentos funcionais no manejo da diabetes mellitus

Objective: To analyze the knowledge and the consumption of functional foods that facilitate the diabetes mellitus control in patients of a public hospital in Curitiba - PR. Materials and Methods: This is a cross-sectional and quantitative study, conducted with diabetic patients hospitalized (Hospital de Clinicas/UFPR), in the period between December 2011 and March 2012. A questionnaire was used for data collection in order to obtain information about the knowledge of functional foods, as well as the consumption of five important functional foods for the diabetes control: garlic, yacon potato, onion, passion fruit peel flour and flaxseed. The collected data were tabulated on Libre Office ® 3.5 and afterwards the analysis were performed using descriptive statistics. Results: It was observed that only 12 patients (35.29%) of the sample had previously received information on functional foods and only 11 (32.35%) respondents know the importance of these foods to control diabetes. Of the five studied functional foods, garlic and potatoes yacon presented the highest consumption among diabetic patients. Conclusion: The knowledge about functional foods, as well as its consumption by diabetic patients is small. There is a need for a greater intervention by Nutrition professionals on the orientation of these foods consumption in the usual diet of diabetic patients, aiming to promote a better control of diabetes mellitus.
