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.

Sulfonylurea receptors (SURs) constitute the regulatory subunits of ATP-sensitive K ؉ channels (K ATP channels). SUR binds nucleotides and synthetic K ATP channel modulators, e.g. the antidiabetic sulfonylurea glibenclamide, which acts as a channel blocker. However, knowledge about naturally occurring ligands of SUR is very limited. In this study, we show that the plant phenolic compound trans-resveratrol can bind to SUR and displace binding of glibenclamide. Electrophysiological measurements revealed that resveratrol is a blocker of pancreatic SUR1/ K IR 6.2 K ATP channels. We further demonstrate that, like glibenclamide, resveratrol induces enhanced apoptosis. This was shown by analyzing different apoptotic parameters (cell detachment, nuclear condensation and fragmentation, and activities of different caspase enzymes). The observed apoptotic effect was specific to cells expressing the SUR1 isoform and was not mediated by the electrical activity of K ATP channels, as it was observed in human embryonic kidney 293 cells expressing SUR1 alone. Enhanced susceptibility to resveratrol was not observed in pancreatic ␤-cells from SUR1 knock-out mice or in cells expressing the isoform SUR2A or SUR2B or the mutant SUR1(M1289T). Resveratrol was much more potent than glibenclamide in inducing SUR1-specific apoptosis. Treatment with etoposide, a classical inducer of apoptosis, did not result in SUR isoform-specific apoptosis. In conclusion, resveratrol is a natural SUR ligand that can induce apoptosis in a SUR isoform-specific manner. Considering the tissue-specific expression patterns of SUR isoforms and the possible effects of SUR mutations on susceptibility to apoptosis, these observations could be important for diabetes and/or cancer research.Sulfonylurea receptors (SURs) 2 are members of the ATPbinding cassette protein family (subfamily C). SURs are known to be the important regulatory subunits of ATP-sensitive K ϩ channels (K ATP channels). These channels are heteromeric complexes composed of four SUR subunits that surround a central pore formed by four subunits from the K IR 6.x family. K ATP channels found in various tissues exhibit distinct physiological and pharmacological properties because of the combination of different subunit isoforms (reviewed in Ref. 1). In addition to two nucleotide-binding domains, SUR possesses binding sites for synthetic K ATP channel modulators. The binding sites for blockers and openers are different, but they are linked via complex allosteric interactions (2, 3).Because of their nucleotide sensitivity, K ATP channels couple the energy metabolism of a cell to the membrane potential. This is important in the pancreatic ␤-cell, in which closure of K ATP channels triggers insulin secretion via membrane depolarization in response to changes in blood glucose levels (4 -6). K ATP channel-blocking drugs such as the sulfonylureas and the glinides can promote insulin secretion and are used in the treatment of diabetes type 2. Insulin secretion is also modulated and amplified by other pathways...

Microincision cataract surgery was a safe and reproducible technique. The postoperative results in the MICS group were comparable to those in the SICS group.

The objectives of this prospective cohort study were to report the incidence, prevalence, and duration of traumatic and overuse injuries during a period of 2.5 years and to estimate the odds of injury types. In all, 1259 schoolchildren, aged 6-12, were surveyed each week with an automated mobile phone text message asking questions on the presence of any musculo-skeletal problems and participation in leisure-time sport. Children were examined and injuries classified as overuse or traumatic. The overall injury incidence and prevalence were 1.2% and 4.6% per week, with 2.5 times more overuse than traumatic injuries in lower extremities, and mean injury duration of 5.3 and 4.8 weeks, respectively. A reverse pattern was found for upper extremities, with 3.1 times more traumatic than overuse injuries and mean durations of 3.3 and 5.2 weeks, respectively. Grade level, school type, leisure-time sport, and seasonal variation were associated with the risk of sustaining lower extremity injuries. Only grade level was associated with upper extremity injuries. The magnitude of overuse and traumatic limb injuries emphasizes the need for health professionals, coaches, and parents to pay special attention in relation to the growing and physically active child.

In 1-5 % of patients during childbearing years recurrent miscarriages (RM) occur. There are established risk factors like anatomical, endocrine and hemostatic disorders as well as immunological changes in the maternal immune system. Nevertheless, further elucidation of the pathogenesis remains a matter of debate. In addition, there are no standardized immunological treatment strategies. Recent studies indicate possible effects of tumor necrosis factor a blocker and granulocyte-colony stimulating factor (G-CSF) concerning live birth rate (LBR) in RM patients. Therefore, we performed a retrospective cohort study in patients undergoing assisted reproductive treatment (ART) with known RM analysing the possible benefits of G-CSF application. From January 2002 to December 2010, 127 patients (199 cylces) with RM (at least 2 early miscarriages) 49 (72 cycles) receiving G-CSF and 78 (127 cycles) controls receiving either no medication (subgroup 1) or Cortisone, intravenous immunoglobulins or low molecular weight heparin (subgroup 2) undergoing ART for in vitro fertilisation/intracytoplasmic sperm injection were analysed. G-CSF was administered weekly once (34 Mill) in 11 patients, 38 patients received 2 9 13 Mill G-CSF per week until the 12th week of gestation. Statistical analysis was performed with SPSS for Windows (19.0), p \ 0.05 significant. The mean age of the study population was 37.3 ± 4.4 years (mean ± standard deviation) and differed not significantly between patients and subgroups. However, the number of early miscarriages was significantly higher in the G-CSF group as compared to the subgroups (G-CSF 2.67 ± 1.27, subgroup 1 0.85 ± 0.91, subgroup 2 0.64 ± 0.74) and RM patients receiving G-CSF had significantly more often a late embryo transfer (day 5) (G-CSF 36.7 %, subgroup 1 12.1 %, subgroup 2 8.9 %). The LBR of patients and the subgroups differed significantly (G-CSF 32 %, subgroup 1 13 %, subgroup 2 14 %). Side effects were present in less than 10 % of patients, consisting of irritation at the injection side, slight leukocytosis, rise of the temperature (\38°C), mild bone pain and hyperemesis gravidarum. None of the newborn showed any kind of malformations. According to our data, G-CSF seems to be a safe and promising immunological treatment option for RM patients. However, with regard to the retrospective setting and the possible bias of a higher rate of late embryo transfers in the G-CSF group additional studies are needed to further strengthen our results.
