Pre-participation screening (PPS) is crucial for assessing the competitive athletes since their risk of sudden death is higher than non-athletes. In Turkey, PPS is performed at the primary health care setting by primary care physicians (PCPs) who are family medicine specialists (FMSs) or general practitioners (GPs). Although there are national guidelines, there is no legal regulation for this process. This study aims to evaluate PCPs’ knowledge, experience, and approach about PPS. We prepared an online survey for PCPs and used non-probabilistic sampling. PPS attitudes and practices were analyzed and compared according to factors such as experience, education, and being GP or FMS. Of the 214 PCPs included in the study, 39.3% were female. The mean age was 44.9 years (SD:8.88). The average work experience was 7.9 years. Most participants were aware of their authorization to perform PPS (89.7%) and had previously prepared it (90.2%). However, 6.5% of them felt confident in performing PPS. Only 13.1% were aware of the guidelines. Almost 25% of the participants stated being informed about the subject at some part of their career, but this did not affect the confidence or referral decisions. In addition to medical history and physical examination, further testing was considered necessary by 96.3% of the participants. Significantly more tests were ordered by GPs than FMSs (p=0.026 and p=0.011, respectively). The accurate referral decision ratio was 59.3%, without difference between FMSs and GPs (p=0.216). We found that awareness of the guidelines was low among PCPs who lack confidence in PPS. These factors collectively increased the tendency for unnecessary further testing and referral. Therefore, the PPS implementation into medical school and residency curriculums and national legal regulation for the process is a necessity in Turkey. 相似文献

Wnt/β-catenin signalling is central to development and its regulation is essential in preventing cancer. Using phosphorylation of Dishevelled as readout of pathway activation, we identified Drosophila Wnk kinase as a new regulator of canonical Wnt/β-catenin signalling. WNK kinases are known for regulating ion co-transporters associated with hypertension disorders. We demonstrate that wnk loss-of-function phenotypes resemble canonical Wnt pathway mutants, while Wnk overexpression causes gain-of-function canonical Wnt-signalling phenotypes. Importantly, knockdown of human WNK1 and WNK2 also results in decreased Wnt signalling in mammalian cell culture, suggesting that Wnk kinases have a conserved function in ensuring peak levels of canonical Wnt signalling. 相似文献

Background
Reconstruction of the head and neck after adequate resection of primary tumor and neck dissection is a challenge. It should be performed at one sitting in advanced tumors. Defects caused by the resection should be closed with flaps which match in color, texture and hair bearing characteristics with the face. Cervicopectoral flap is a one such flap from chest and neck skin mainly used to cover the cheek defects. 相似文献5.

This study demonstrates the debilitative effect of a coelomic gregarine, Diplocystis tipulae, on Tipula paludosa. The larvae were provided contaminated fresh grass leaves from a field where 40.0% of T. paludosa larvae were infected by this pathogen. Resultant infected larvae were separated into four groups according to infection level. Analysing their weights, lengths, and weight/length ratios showed that larval size decreased as infection level increased. Differences, especially at the lower and upper levels of the infection levels, were statistically significant. It was concluded that infection by D. tipulae affected the size of T. paludosa larvae resulting in smaller individuals. 相似文献

We investigated whether 8-week treadmill training strengthens antioxidant enzymes and decreases lipid peroxidation in rat heart. The effects of acute exhaustive exercise were also investigated. Male rats (Rattus norvegicus, Sprague-Dawley strain) were divided into trained and untrained groups. Both groups were further divided equally into two groups where the rats were studied at rest and immediately after exhaustive exercise. Endurance training consisted of treadmill running 1.5 h day(-1), 5 days week(-1) for 8 weeks. For acute exhaustive exercise, graded treadmill running was conducted. Malondialdehyde level in heart tissue was not affected by acute exhaustive exercise in untrained and trained rats. The activities of glutathione peroxidase and glutathione reductase enzymes decreased by both acute exercise and training. Glutathione S-transferase and catalase activities were not affected. Total and non-enzymatic superoxide scavenger activities were not affected either. Superoxide dismutase activity decreased by acute exercise in untrained rats; however, this decrease was not observed in trained rats. Our results suggested that rat heart has sufficient antioxidant enzyme capacity to cope with exercise-induced oxidative stress, and adaptive changes in antioxidant enzymes due to endurance training are limited. 相似文献
