The Portuguese National Programme for the Promotion of Healthy Eating: 2012–2015

This paper describes the first 4-year period (2012–2015) of implementation of the Portuguese National Programme for the Promotion of Healthy Eating (PNPAS). PNPAS was approved in 2012 and emerged as a preventive programme for noncommunicable diseases, aiming to improve the nutritional status of the population; it represents the first national strategy in Portugal for the promotion of healthy eating. To accomplish its mission, and taking into account its overall principles, PNPAS has five main goals: (i) to increase knowledge about the food intake of the Portuguese population and about its determinants and consequences; (ii) to modify the availability of certain foods (high in sugar, salt and fat), in schools, workplaces and public spaces; (iii) to inform and empower the population for the purchase, preparation and storage of healthy food, especially the most vulnerable groups; (iv) to identify and promote crosssectoral actions that encourage the consumption of foods of good nutritional quality in an articulate and integrated way with other sectors, namely agriculture, sport, environment, education, social security and local authorities; and (v) to improve the qualifications and conduct of the different professionals who, owing to their roles, may influence nutritional knowledge, attitudes and behaviours. The design of PNPAS followed the latest strategic lines suggested by WHO and the European Commission, proposing a crosssectoral mix of interventions to ensure physical and economic access to healthy eating by creating healthy environments and empowering individuals and communities. Several actions were implemented at different levels during the first 4-year period of implementation of PNPAS; two were especially relevant. The first concerned the empowerment of citizens regarding healthy eating, where the most important aspect was introduction of a digital strategy through development of a website and a blog dedicated to healthy eating. The second concerned the development of documents for health care and other professionals, including several guidelines in new areas, such as anthropometric measures and intervention in preobesity. Process and output indicators were defined to monitor and evaluate the programme. Among those considered as output indicators were the evaluation of childhood obesity, salt consumption and intake of breakfast by school-aged children.

Successful prevention of transmission of integrase resistance in the Swiss HIV Cohort Study.

Prevalence of integrase inhibitor (INSTI) transmitted drug resistance (TDR) may increase with the increasing use of INSTIs. We analysed the prevalence of INSTI TDR in the Swiss HIV Cohort Study (2008-2014). In 1 of 1,316 (0.1%) drug-naïve samples a major INSTI TDR mutation was detected. Prevalence was stable although INSTIs were increasingly used. We showed that this is in contrast to the introduction of previous drug classes where more treatment failures with resistant strains occurred and TDR was observed more rapidly. We demonstrated on a population-level that it is possible to avoid TDR affecting a new drug class for years.

Prevention of cement leakage into the hip joint by a standard cement plug during PFN-A cement augmentation: a technical note.

Medial penetration of the helical blade into the hip joint after fixation of trochanteric fractures using the proximal femur nail antirotation (PFN-A) is a potential failure mode. In low demand patients a blade exchange with cement augmentation may be an option if conversion to total hip arthroplasty is unfeasible to salvage the cut-through. This article describes a technique to avoid intraarticular cement leakage using a cement plug to close the defect in the femoral head caused by the cut-through.
