Primary schools contribute to promoting healthy eating behaviour and preventing overweight and obesity by providing nutrition education. Research highlights the importance of improving teachers’ programme implementation to enhance intervention effectiveness. An integrative approach has been suggested to reduce time barriers that teachers currently experience in teaching nutrition. This scoping review explores use and effectiveness of integrative teaching in primary-school-based nutrition education programmes. Six databases were searched for primary-school-based interventions on nutrition education. Papers reporting on integration of nutrition topics within core curriculum were included. Abstracts and full texts of potentially relevant articles were screened to determine eligibility. Next, data were extracted and tabulated. Findings were collated and summarised to describe intervention characteristics, subject integration and effectiveness of the included programmes. Data describing integration of nutrition into the primary school curriculum were extracted from 39 eligible papers. Nutrition education programmes often involve lessons about food groups and are frequently embedded within the mathematics, science or literacy syllabus. Although articles report on the integration of nutrition, the use of this approach was not commonly described in detail. Only seven papers discussed student outcomes related to the integration of nutrition education within core subjects. The ability to draw strong conclusions about school-based nutrition intervention effectiveness is limited by the current lack of programme description and methodological issues. Hence, more research is warranted to inform evidence on effectiveness of integrative nutrition education for both teacher and student outcomes. Future studies that include greater detail regarding the integrative approach are needed.

Astronomy has largely relied on imagery and innovative data mining techniques. This article briefly illustrates the use of machine learning to create agricultural production data sets from satellite imagery to answer different development questions. Of late, astronomy has also relied on citizen science in the identification of new galaxies (a case in point is the Galaxy Zoo project). The use of citizen science in the examination of changes in urban informality patterns in developing countries (another development question) is also discussed.

A growing awareness of environmental issues in Canada has had a major influence on government policies. An initiative was launched by the government of Ontario to promote research toward the development of an integrated weed management (IWM) system. Research in IWM must take all aspects of the cropping system into consideration and evolve in a progressive manner. This approach must encompass the role of conservation tillage, knowledge of the critical period of weed interference, alternative methods of weed control, enhancement of crop competitiveness, modeling of crop-weed interference, influence of crop rotation and seed bank dynamics, and education and extension of the findings. The complexity involved in addressing these issues requires a multi-disciplinary approach.

Faced with a patient who has extensive esthetic enhancement demands, simply aligning the teeth and achieving a functional occlusion might not suffice.

The goal of this article is to help orthodontists to analyze and to optimize the positioning of upper anterior teeth so as to improve the esthetics of the smile.

Of course, esthetics is not an objective notion. Therefore, maintaining good communication with our patients is essential. Nonetheless, esthetic rules as they are defined in the literature will serve as a “framework” for creating a smile.

In this context, the orthodontist will have to take into account the shape of the teeth, particularly since not all shapes are ideal. In fact, the incisors have three main shapes: rectangular, triangular and ovoid. The shape of the teeth will perhaps guide orthodontists in their choice of treatment. Opting for stripping will be the preferred treatment in some cases.

Similarly, orthodontists have to take into consideration incisal edge defects caused by wear associated with the initial malocclusion that becomes more apparent after alignment. In some cases, a simple recontouring or enameloplasty of the incisal edges will be sufficient and should be discussed with the patient before it is performed using a simple and reliable procedure.

The objective of this article is to offer a simplified and reasonable approach for periodontal disease screening that should be a mandatory part of each and every oral examination. The main purpose of this examination is to answer the question of whether or not there are any infection sites that require periodontal management. This assessment has three parts: the initial patient interview (medical history), the clinical oral examination and the radiological examination. Using a periodontal probe, the dentist should place a high priority on performing PD screening and it should be done systematically and routinely during every consultation. Orthodontists and dentists are both licensed to perform this examination. After this examination, the practitioner can make a diagnosis, initiate periodontal management of the patient or refer the patient to an appropriate specialist.

PD screening should be repeated before orthodontic treatment or before any functional rehabilitation in order to maintain periodontal stability.

This Supplement to Cardiology in the Young represents the ninth annual supplement generated from the two meetings that compose “HeartWeek in Florida”. “HeartWeek in Florida”, the joint collaborative project sponsored by the Cardiac Center at the Children's Hospital of Philadelphia, together with All Children's Hospital of Saint Petersburg and the Congenital Heart Institute of Florida, averages over 1000 attendees every year and is now recognized as one of the major planks of continuing medical and nursing education for those working in the fields of diagnosis and treatment of cardiac disease in the fetus, neonate, infant, child, and adult. “HeartWeek in Florida” combines the International Symposium on Congenital Heart Disease, now organised by All Children's Hospital and Johns Hopkins Medicine and entering its 12th year, with the Annual Postgraduate Course in Pediatric Cardiovascular Disease organised by Children's Hospital of Philadelphia and entering its 16th year. The theme of this supplement generated from the 2011 HeartWeek in Florida is “A Holistic Approach to Hypoplastic Left Heart Syndrome and Other Evolving Challenges in Paediatric and Congenital Cardiac Disease”. We would like to acknowledge the tremendous contributions made to medicine by Martin Elliott and Gil Wernovsky; and therefore, we dedicate this HeartWeek 2011 Supplement to them.

All 67-year-old pensioners in a primary care district (N = 142) participating in a multi-disciplinary population study were followed until the age of 83. At 83 years of age, 65 persons had survived and continued to take part in the study. Social, psychological and medical factors predicting survival during the period have previously been reported (Samuelsson et al. 1992). In the present analysis, the same variables at age 67 were used to predict health, measured with six different health indicators, at 83 years. The analysis has been performed separately for women and men. Variables at 67 years of age as determinants for health at age 83 have been identified and ranked through successive selection in a step-wise discriminatory analysis. For women, reported diseases at 67 was a very strong predictor but quite the contrary for men. Blood pressure and sleep medication were strong predictors for men but not for women. Psychological factors were more frequently included in the predictive models for women than for men. Social factors were of comparatively less importance for both men and women. There was greater accuracy in the prediction of health for women. The individual variables most often included in the predictive model for women were coping and reported health at age 67. For men, blood pressure, sleep medication and intelligence were the most frequent predictors. The analysis demonstrated clear sex-specific prediction patterns. When comparing predictors for survival and predictors for differentiated health in the same population no similarities were found.
