Non communicable diseases (NCDs) become symptomatic in adulthood, but they mainly origin from early life. As NCDs are the major cause of mortality both in developed and developing countries, global actions are necessary for their life course prevention and control. The main preventable risk factors of NCDs include tobacco use, unhealthy diet, and physical inactivity. These risk factors track from childhood to adulthood; it is well documented that healthy lifestyles play an important role for primordial and primary prevention of NCDs. Sedentary lifestyle, especially prolonged screen time, is a main underlying factor for NCDs. Regarding dietary intake, lower consumption of fruits, vegetables and fibers, as well as higher consumption of fatty and salty foods (fast foods, junk food), and carbonated soft drinks are of most usual habits correlated with increased risk of NCDs.Strategic action areas for the prevention and control of NCDs are health promotion, risk reduction, health systems strengthening for early detection and management of NCD risk factors. Low-cost solutions for reduction the common modifiable risk factors including unhealthy life-cycle are important for guiding policy and priorities of governments and for decreasing the prevalence of NCDs.

OBJECTIVE: To assess effects of increasing omega-3, omega-6, and total polyunsaturated fatty acids (PUFA) on diabetes diagnosis and glucose metabolism. DESIGN: Systematic review and meta-analyses. DATA SOURCES: Medline, Embase, Cochrane CENTRAL, WHO International Clinical Trials Registry Platform,, and trials in relevant systematic reviews. ELIGIBILITY CRITERIA: Randomised controlled trials of at least 24 weeks' duration assessing effects of increasing α-linolenic acid, long chain omega-3, omega-6, or total PUFA, which collected data on diabetes diagnoses, fasting glucose or insulin, glycated haemoglobin (HbA1c), and/or homoeostatic model assessment for insulin resistance (HOMA-IR). DATA SYNTHESIS: Statistical analysis included random effects meta-analyses using relative risk and mean difference, and sensitivity analyses. Funnel plots were examined and subgrouping assessed effects of intervention type, replacement, baseline risk of diabetes and use of antidiabetes drugs, trial duration, and dose. Risk of bias was assessed with the Cochrane tool and quality of evidence with GRADE. RESULTS: 83 randomised controlled trials (mainly assessing effects of supplementary long chain omega-3) were included; 10 were at low summary risk of bias. Long chain omega-3 had little or no effect on likelihood of diagnosis of diabetes (relative risk 1.00, 95% confidence interval 0.85 to 1.17; 58 643 participants, 3.7% developed diabetes) or measures of glucose metabolism (HbA1c mean difference -0.02%, 95% confidence interval -0.07% to 0.04%; plasma glucose 0.04, 0.02 to 0.07, mmol/L; fasting insulin 1.02, -4.34 to 6.37, pmol/L; HOMA-IR 0.06, -0.21 to 0.33). A suggestion of negative outcomes was observed when dose of supplemental long chain omega-3 was above 4.4 g/d. Effects of α-linolenic acid, omega-6, and total PUFA on diagnosis of diabetes were unclear (as the evidence was of very low quality), but little or no effect on measures of glucose metabolism was seen, except that increasing α-linolenic acid may increase fasting insulin (by about 7%). No evidence was found that the omega-3/omega-6 ratio is important for diabetes or glucose metabolism. CONCLUSIONS: This is the most extensive systematic review of trials to date to assess effects of polyunsaturated fats on newly diagnosed diabetes and glucose metabolism, including previously unpublished data following contact with authors. Evidence suggests that increasing omega-3, omega-6, or total PUFA has little or no effect on prevention and treatment of type 2 diabetes mellitus.

Guidelines emphasize the importance of approaching substance use by adolescents, particularly in primary health care. However, there are problems with its incorporation. The objective of this study was to present the training stages on the theme for professionals in primary health care. Researchers conducted logistic structuring, content elaboration and evaluation of difficulties before and after training. Sixty percent of professionals involved in the care of adolescents in a medium-sized city participated in the study. More than half of them stated having difficulties in the approach, mainly theoretical limitations and short consultations. After the training, the professionals informed whether they felt more prepared, but practical difficulties remained.

El embarazo y el parto constituyen hechos trascendentales en la vida de la mujer; son momentos de alta carga sentimental y emocional, que implican múltiples cambios biológicos en la madre. Estos constituyen procesos que pueden estar marcados por diferentes factores de riesgo que están presentes muchas veces en la etapa preconcepcional y que se exacerban entre las embarazadas adolescentes. Al respecto se presenta una revisión bibliográfica que recoge información teórica, epidemiológica y sobre algunas formas para prevenir los respectivos factores predisponentes.

Pregnancy and childbirth are transcendental events in the life of women. They are moments of high sentimental and emotional charge, which imply multiple biological changes in the mother. These ones constitute processes that can be marked by different risk factors that are present many times in the preconceptional stage and that are exacerbated among pregnant adolescents. In this regard, a bibliographic review is presented, which gathers theoretical and epidemiologi-cal information and some ways to prevent the respective predisposing factors.

INTRODUCTION: The role of aspirin as a means of primary prevention remains controversial. AIM: We have conducted a meta-analysis of all randomized controlled trials (RCTs) to evaluate the role of aspirin in primary prevention. METHODS: Literature search was performed via PubMed, Embase, and the Cochrane Library for all related RCTs. All-cause mortality was the primary endpoint. Secondary endpoints included major adverse cardiovascular events (MACE), myocardial infarction (MI), cardiovascular mortality, cerebrovascular events, and bleeding events. We used a random effects model to report the risk ratios (RRs) with 95% confidence intervals (CIs). RESULTS: Our analysis included 17 RCTs (164,862 patients; 83,309 received aspirin and 81,744 received placebo). Our study did not demonstrate any significant reduction in all-cause mortality for patients treated with aspirin when compared with placebo (RR 0.97; 95% CI 0.93-1.01; P = 0.13). Sensitivity analysis performed by excluding healthy elderly (≥ 65) showed significant reductions in all-cause mortality in the aspirin-treated patients (RR 0.94; 95% CI 0.90-0.99; P = 0.01). There were no significant differences between both groups regarding cardiovascular mortality and cerebrovascular events (P > 0.05). However, aspirin-treated patients significantly reduced MACE and MI events (RR 0.89; 95% CI 0.85-0.93; P < 0.001 and RR 0.88; 95% CI 0.78-0.98; P = 0.02, respectively), respectively. However, aspirin was associated with a significantly higher incidence of bleeding, including major bleeding and intracranial bleeding (P < 0.001). CONCLUSIONS: Aspirin use in primary prevention has resulted in a lower incidence of MACE and MI without significantly effecting cerebrovascular events. However, aspirin was associated with a higher bleeding risk. Use of aspirin as a means of primary prevention should be thoroughly discussed with patients and pursued based on the risk of cardiovascular disease while also considering bleeding risk.

Modern strategies of primary prevention of cardiovascular complications of atherosclerotic etiology are presented in this article: traditional approach based on assessment of risk of development of complication and coming to replace it concept of prevention based on direct application of results of prospective clinical studies. The article contains detailed presentation of new opportunities of computer tomography of the heart allowing to substantially elevate precision of assessment of risk of cardiovascular complications of atherosclerotic etiology. Main attention is paid to the coronary artery calcification index, which determination substantially simpli- fies decision making relative to strategy of primary prevention in clinical practice.

BACKGROUND: Harmful alcohol use is a modifiable risk factor contributing to the increasing burden of non-communicable diseases and deaths and the implementation of policies focused on primary prevention is pivotal to address this challenge. Policies with actions targeting the harmful use of alcohol have been developed in Nigeria. This study is an in-depth analysis of alcohol-related policies in Nigeria and the utilization of WHO Best Buy interventions (BBIs) and multi-sectoral action (MSA) in the formulation of these policies. METHODS: A descriptive case study design and the Walt and Gilson framework of policy analysis was utilized for the research. Components of the study included a scoping review consisting of electronic search of Google and three online databases (Google Scholar, Science Direct and PubMed) to identify articles and policy documents with no language and date restrictions. Government institution provided documents which were not online. Thirteen policy documents, reports or articles relevant to the policy formulation process were identified. Other components of the study included interviews with 44 key informants (Bureaucrats and Policy Makers) using a pretested guide. The qualitative data were coded and analyzed using thematic analysis. RESULTS: Findings revealed that policy actions to address harmful alcohol use are proposed in the 2007 Federal Road Safety Act, the Non-communicable Diseases Prevention and Control Policy and the Strategic Plan of Action. Only one of the best buy interventions, (restricted access to alcohol) is proposed in these policies. Multi-sectoral action for the formulation of alcohol-related policy was low and several relevant sectors with critical roles in policy implementation were not involved in the formulation process. Overall, alcohol currently has no holistic, health-sector led policy document to regulate the marketing, promotion of alcohol and accessibility. A major barrier is the low government budgetary allocation to support the process. CONCLUSIONS: Nigeria has few alcohol-related policies with weak multi-sectoral action. Funding constraint remains a major threat to the implementation and enforcement of proposed policy actions.

BACKGROUND: To assess the immune persistence conferred by a Chinese hamster ovary (CHO)-derived hepatitis B vaccine (HepB) 17 to 20 years after primary immunization during early life. METHODS: Participants born between 1997 and 1999 who received a full course of primary vaccination with HepB (CHO) and who had no experience with booster vaccination were enrolled. Blood samples were required from each participant for measurement of hepatitis B surface antibody (anti-HBs), surface antigen and core antibody levels. For those who possessed an anti-HBs antibody < 10 mIU/mL, a single dose of HepB was administered, and 30 days later, serum specimens were collected to assess the booster effects. RESULTS: A total of 1352 participants were included in this study. Of these, 1007 (74.5%) participants could retain an anti-HBs antibody ≥10 mIU/mL, with a geometric mean concentration (GMC) of 57.4 mIU/mL. HBsAg was detected in six participants, resulting in a HBsAg carrier rate of 0.4% (6/1352). Of those participants with anti-HBs antibodies < 10 mIU/mL, after a challenge dose, 231 (93.1%) presented an anti-HBs antibody ≥10 mIU/mL, with a GMC of 368.7 mIU/mL. A significant increase in the anti-HBs positive rate (≥ 10 mIU/mL) after challenge was observed in participants with anti-HBs antibodies between 2.5 and 10 mIU/mL and participants boosted with HepB (CHO), rather than those with anti-HBs antibodies < 2.5 mIU/mL and those boosted with HepB (SC). CONCLUSION: Since satisfactory immune protection against HBV infection conferred by primary vaccination administered 17-20 years ago was demonstrated, there is currently no urgent need for booster immunization.

Aspirin is one of the most frequently used drugs worldwide and is generally considered effective for the secondary prevention of cardiovascular disease. By contrast, the role of aspirin in primary prevention of cardiovascular disease is controversial. Early trials evaluating aspirin for primary prevention, done before the turn of the millennium, suggested reductions in myocardial infarction and stroke (although not mortality), and an increased risk of bleeding. In an effort to balance the risks and benefits of aspirin, international guidelines on primary prevention of cardiovascular disease have typically recommended aspirin only when a substantial 10-year risk of cardiovascular events exists. However, in 2018, three large randomised clinical trials of aspirin for the primary prevention of cardiovascular disease showed little or no benefit and have even suggested net harm. In this narrative Review, we reappraise the role of aspirin in primary prevention of cardiovascular disease, contextualising data from historical and contemporary trials.

BACKGROUND: Tuberculosis causes more deaths than any other infectious disease globally. Bacillus Calmette-Guérin (BCG) is the only available vaccine, but protection is incomplete and variable. The modified Vaccinia Ankara virus expressing antigen 85A (MVA85A) is a viral vector vaccine produced to prevent tuberculosis. OBJECTIVES: To assess and summarize the effects of the MVA85A vaccine boosting BCG in humans. SEARCH METHODS: We searched the Cochrane Infectious Diseases Group Specialized Register; Central Register of Controlled Trials (CENTRAL); MEDLINE (PubMed); Embase (Ovid); and four other databases. We searched the WHO ICTRP and All searches were run up to 10 May 2018. SELECTION CRITERIA: We evaluated randomized controlled trials of MVA85A vaccine given with BCG in people regardless of age or HIV status. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed the eligibility and risk of bias of trials, and extracted and analyzed data. The primary outcome was active tuberculosis disease. We summarized dichotomous outcomes using risk ratios (RR) and risk differences (RD), with 95% confidence intervals (CI). Where appropriate, we combined data in meta-analyses. Where meta-analysis was inappropriate, we summarized results narratively. MAIN RESULTS: The search identified six studies relating to four Phase 2 randomized controlled trials enrolling 3838 participants. Funding was by government bodies, charities, and philanthropic donors. Five studies included infants, one of them infants born to HIV-positive mothers. One study included adults living with HIV. All trials included authors from Oxford University who led the laboratory development of the vaccine. Participants received intradermal MVA85A after BCG in some studies, and before selective deferred BCG in HIV-exposed infants.The largest trial in 2797 African children was well conducted with low risk of bias for most parameters. Risk of bias was uncertain for selective reporting because there were no precise case definition endpoints for active tuberculosis published prior to the trial analysis.MVA85A added to BCG compared to BCG alone probably has no effect on the risk of developing microbiologically confirmed tuberculosis (RR 0.97, 95% CI 0.58 to 1.62; 3439 participants, 2 trials; moderate-certainty evidence), or the risk of starting on tuberculosis treatment (RR 1.10, 95% CI 0.92 to 1.33; 3687 participants, 3 trials; moderate-certainty evidence). MVA85A probably has no effect on the risk of developing latent tuberculosis (RR 1.01, 95% CI 0.85 to 1.21; 3831 participants, 4 trials; moderate-certainty evidence). Vaccinating people with MVA85A in addition to BCG did not cause life-threatening serious adverse effects (RD 0.00, 95% CI -0.00 to 0.00; 3692 participants, 3 trials; high-certainty evidence). Vaccination with MVA85A is probably associated with an increased risk of local skin adverse effects (3187 participants, 3 trials; moderate-certainty evidence), but not systemic adverse effect related to vaccination (144 participants, 1 trial; low-certainty evidence). This safety profile is consistent with Phase 1 studies which outlined a transient, superficial reaction local to the injection site and mild short-lived symptoms such as malaise and fever. AUTHORS' CONCLUSIONS: MVA85A delivered by intradermal injection in addition to BCG is safe but not effective in reducing the risk of developing tuberculosis.

INTRODUÇÃO: A dengue é uma arbovirose, transmitida para o homem através da picada do mosquito Aedes aegypti, e que acomete grande número de indivíduos no mundo. Nos últimos 50 anos, junto com o aumento da expansão geográfica, a incidência de dengue aumentou aproximadamente 30 vezes. Ao longo dos anos, diversas medidas de combate à dengue foram implementadas, a partir daí, no ano de 2004 foi possível evidenciar que houve redução de 290% nos casos de dengue em relação ao ano anterior. OBJETIVO: Descrever o conhecimento de escolares do Rio Grande do Sul sobre o tema dengue. MÉTODOS: Estudo com abordagem quantitativa do tipo descritiva realizado com jovens alunos da rede pública de educação da cidade de Tupãnciretã, por meio de um questionário estruturado. RESULTADOS: Evidenciou-se que a maioria dos alunos tinha conhecimento sobre como a dengue é transmitida, sendo que 35% acreditavam que a fêmea do mosquito transmite a doença e ainda, 58,8% afirmaram que conseguem reconhecer o mosquito. Uma parcela dos alunos acredita que o mosquito pica preferencialmente durante o dia, onde a principal forma de transmissão selecionada foi "O mosquito pica uma pessoa doente e transmite a doença à outra pessoa" e os principais sintomas assinalados foram febre, dor de cabeça e cansaço. CONCLUSÃO: O estudo demonstrou que boa parte dos jovens possuem conhecimentos sobre a dengue, entretanto, ainda há crianças e adolescentes que não conhecem o assunto, trazendo à tona a importância deste tema nas campanhas de saúde.

INTRODUCTION: Dengue is an arbovirus, transmitted to humans through the bite of the Aedes aegypti mosquito, and which affects a large number of individuals in the world. Over the past 50 years, along with increased geographic expansion, the incidence of dengue increased approximately 30-fold. Over the years, several measures to combat dengue have been implemented and due to this factor, in 2004, there was a 290% reduction in dengue cases in relation to the previous year. OBJECTIVE: To describe the knowledge of schoolchildren from Rio Grande do Sul on the subject of dengue. METHODS: A quantitative descriptive study carried out with young students of the public education system of the city of Tupãnciretã, through a structured questionnaire. RESULTS: It was evidenced that most of the students had knowledge about how dengue is transmitted, 35% believed that the mosquito female transmits the disease and 58.8% claim to be able to recognize the mosquito. A significant portion of the students believe that the mosquito bites preferentially during the day, where the main form of transmission selected was "The mosquito bites a sick person and transmits the disease to the other person" and the main symptoms were fever, headache and tiredness. CONCLUSION: The study showed that most of the young people have knowledge about dengue, however, there are still children and adolescents who do not know the subject, bringing to the fore the importance of this theme in health campaigns.
