BackgroundAn increasingly passive life-style in the Western World has led to a rise in life-style related disorders. This is a major concern for all segments of society. The county council of the municipality of Svendborg in Denmark, created six Sport Schools with increased levels of suitable physical activities, which made it possible to study the health outcomes in these children whilst comparing them to children who attended the ‘normal’ schools of the region using the design of a “natural experiment”.MethodsChildren from the age of 6 till the age of 10, who accepted to be included in the monitoring process, were surveyed at baseline with questionnaires, physical examinations and physical and biological testing, including DXA scans. The physical examination and testing was repeated during the early stage of the study. Every week over the whole study period, the children will be followed with an automated mobile phone text message (SMS-Track) asking questions on their leisure time sports activities and the presence of any musculoskeletal problems. Children who report any such problems are monitored individually by health care personnel. Data are collected on demography, health habits and attitudes, physical characteristics, physical activity using accelerometers, motor performance, fitness, bone health, life-style disorders, injuries and musculoskeletal problems. Data collection will continue at least once a year until the children reach grade 9.DiscussionThis project is embedded in a local community, which set up the intervention (The Sport Schools) and thereafter invited researchers to provide documentation and evaluation. Sport schools are well matched with the ‘normal’ schools, making comparisons between these suitable. However, subgroups that would be specifically targeted in lifestyle intervention studies (such as the definitely obese) could be relatively small. Therefore, results specific to minority groups may be diluted. Nonetheless, the many rigorously collected data will make it possible to study, for example, the general effect that different levels of physical activity may have on various health conditions and on proxy measures of life-style conditions. Specifically, it will help answer the question on whether increased physical activity in school has a positive effect on health in children.

Risk factors for lens opacification after implantation of the model V4 ICL included intraoperative trauma to the crystalline lens and older age. Decreased ECD in eyes with opacification suggests ongoing inflammation as a cause. Patients younger than 45 years may have a significantly lower incidence of opacification.

In recent years, multidisciplinary pain programs were seen to successfully treat patients by basing treatment on a combination of physical exercise and psychological interventions. However, in spite of their effectiveness, it still remains to be clarified exactly which features of these programs were responsible for patient improvement. Cognitive-behavioral models posit that improvement is due, in part, to changes in patient coping strategies. Nonetheless, as reflected by the conflicting opinions present in the literature, it is questionable whether a so-called 'cognitive shift' is an accurate indicator for return to work of disabled patients. Ninety patients with chronic low back pain took part in a multidisciplinary treatment program. Therapeutic environment reinforces wellness behavior and enhances the patients' sense of control over their pain and resulting disability. The main therapeutic target point was to facilitate return to work. Ways of coping were measured by a well studied coping inventory in the German language (FEKB). Factor analysis revealed three factors: 'catastrophizing', 'search for information' and 'cognitive control'. In addition, assessment included measurements of pain intensity, depression, disability, flexibility of the lumbar spine, and different performance parameters. All of them were measured prior to and at the end of treatment, and following intervals of 6 and 12 months after discharge from program. Measurements showed significant changes over time, but more importantly, nearly all results were seen to stabilize at the 6- and 12-month evaluation following treatment. The coping strategies demonstrated little or poor change. In addition, coping measures and change in coping behavior showed poor prognostic relevance. But other psycho-social parameters like self-evaluation of potential return-to-work, application for pension, the length of pre-absence from work, and a decrease in subjective disability following treatment were effective indicators for 'back-to-work'. Other objective parameters, such as medical history, physical impairment and general physical variables were seen to have little predictive value in determining a return to work. The results suggest that the primary target point for further investigation is the analysis of the patients' beliefs about their pain. Our results indicate that future research must be attentive to the complex interactions between environmental factors and the coping demands posed by the specific nature of pain problems.
