“…The methodologies used for the elaboration of this review were similar to those employed in systematic reviews. [13][14][15][16] Research strategy Our investigation was carried out using the Pubmed electronic database. The following combined descriptors were used: Prevention and Educational Activities and Hypertension; Prevention and Educational Activities and Obesity; Prevention and Educational Activities and Diabetes.…”

Objective:The main goal of this work was to produce a review of educational strategies to prevent diabetes, hypertension, and obesity. Method: PubMed database was consulted using combined descriptors such as [Prevention] Results: A total of 8,908 articles were found, of which 1,539 were selected about diabetes mellitus (DM, n=369), arterial systemic hypertension (ASH, n=200), and obesity (OBES, n=970). The number of free full text articles available was 1,075 (DM = 276, ASH = 118 and OBES = 681). In most of these studies, demographic characteristics such as gender and age were randomized, and the population mainly composed by students, ethnic groups, family members, pregnant, health or education professionals, patients with chronic diseases (DM, ASH, OBES) or other comorbidities. Group dynamics, physical activity practices, nutritional education, questionnaires, interviews, employment of new technologies, people training and workshops were the main intervention strategies used. Conclusion:The most efficient interventions occurred at community level, whenever the intervention was permanent or maintained for long periods, and relied on the continuous education of community health workers that had a constant interference inside the population covered. Many studies focused their actions in children and adolescents, especially on students, because they were more influenced by educational activities of prevention, and the knowledge acquired by them would spread more easily to their family and to society.

“…66 We attempted to detect this source of bias through the construction of funnel plots. 54 This plot allowed us to assess, through visual inspection, whether most of the articles that were included in our analysis reported positive results. Fortunately, it appeared that there were an approximately equal number of both positive and negative trials making publication bias less likely.…”

“…Publication bias was investigated through visual inspection of funnel plots whereby ORs were plotted against study sample size. 54 Cumulative analysis ordered by publication date was also performed on the PONV and vomiting endpoints to determine the contribution of successive trials to the pooled results. The number needed to treat (NNT) was calculated for the efficacy outcomes of PONV and vomiting and the number need to harm (NNH) was calculated for the toxicity parametres.…”

Purpose: Numerous antiemetics have been studied for the prevention of postoperative nausea and vomiting (PONV) including traditional agents (metoclopramide, perphenazine, prochlorperazine, cyclizine and droperidol) and the 5-HT 3 receptor antagonists (ondansetron, dolasetron, granisetron and tropisetron). The results have been divergent and inconsistent. The purpose of this quantitative systematic review was to evaluate the effectiveness of 5HT 3 receptor antagonists compared to traditional antiemetics for the prevention of PONV. Methods: A systematic search of the English language literature using computerized MEDLINE, EMBASE, and Pre-MEDLINE databases from 1966 to October 1999 and a manual search of references from retrieved articles were performed. Individual efficacy and adverse effect data was extracted from each of the studies according to a predefined protocol. The summary odds ratios were calculated using the Dersimonian and Laird method under a random effects model. Results: A total of 41 trials met our pre-defined inclusion criteria and were included in our analysis.
