CORRELATION OF ANXIETY AND CHRONIC PAIN TO GRADE OF SYNOVITIS IN PATIENTS WITH KNEE OSTEOARTHRITIS

Background: This study was conducted with the objective of finding out the correlation between synovial inflammation measured histopathologically and subjective symptoms; anxiety and chronic pain, in knee osteoarthritis (OA). Subjects and methods: Thirty patients were included in the study. Ten of them were in a control group with meniscal injury, ten had early OA and 10 had late OA. Knee radiographs were graded using Kellgren-Lawrence classification. Synovial biopsies were taken during surgery or arthroscopy and synovitis score was measured by Krenns method. Anxiety was measured with Beck Anxiety Inventory and pain was taken as part of the WOMAC score (The Western Ontario and McMaster Universities Arthritis Index). Results: Krenn synovitis score was determined as: no synovitis, low-grade synovitis and high-grade synovitis. Group with lowgrade synovitis had significantly higher pain score than high-grade synovitis group (p=0.011). No-synovitis group had significantly lower Beck Anxiety Inventory than low-grade synovitis group (p=0.014) and high-grade synovitis (p=0.008). There are no significant differences between low-grade synovitis and high-grade synovitis in anxiety score (p=0.912). Conclusions: Chronic pain is more present in late osteoarthritis, when synovitis is less pronounced. Anxiety affects patients who suffer osteoarthritis, but it is statistically the same regarding synovitis grade, i.e. whether it is early or late osteoarthritis

A retrospective survey on injuries in Croatian football/soccer referees

BACKGROUND: Injury among soccer referees is rarely studied, especially with regard to differences in the quality level of the refereeing. Additionally, we have found no study that has reported injury occurrence during official physical fitness testing for soccer referees. The aim of this study was to investigate the frequency, type and consequences of match-related and fitness-testing related injuries among soccer referees of different competitive levels. METHODS: We studied 342 soccer referees (all males; mean age 32.9 ± 5.02 years). The study was retrospective, and a self-administered questionnaire was used. In the first phase of the study, the questionnaire was tested for its reliability and applicability. The questionnaire included morphological/anthropometric data, refereeing variables, and musculoskeletal disorders together with the consequences. RESULTS: The sample comprised 157 main referees (MR; mean age 31.4 ± 4.9 years) and 185 assistant referees (AR; mean age 34.1 ± 5.1 years) divided into: international level (Union of European Football Associations-UEFA) referees (N = 18; 6 MRs; 12 ARs) ; 1(st) (N = 78; 31 MRs; 47 ARs), 2(nd) (N = 91; 45 MRs; 46 ARs); or 3(rd) national level referees (N = 155; 75 MRs; 80 ARs). In total, 29% (95%CI: 0.23–0.37) of the MRs and 30% (95%CI: 0.22–0.36) of the ARs had experienced an injury during the previous year, while 13% (95%CI: 0.05–0.14) of the MRs, and 19% (95%CI: 0.14–0.25) of the ARs suffered from an injury that occurred during fitness testing. There was an obvious increase in injury severity as the refereeing advanced at the national level, but the UEFA referees were the least injured of all referees. The results showed a relatively high prevalence of injuries to the upper leg (i.e., quadriceps and hamstrings) during physical fitness testing for all but the UEFA referees. During game refereeing, the ankles and lower legs were the most commonly injured regions. The MRs primarily injured their ankles. The ARs experienced lower leg and lower back disorders. However, the overall injury rate was equal for both groups, with 5.29 (95%CI: 2.23–8.30) and 4.58 (95%CI: 2.63–6.54) injuries per 1000 hours of refereeing for MRs and ARs, respectively. CONCLUSION: In addition to the reported risk of injury during soccer games, physical fitness testing should be classified as a risk for injury among soccer referees. Special attention should be given to (I) lower leg injuries during games and (II) upper leg injuries during physical fitness tests. A higher physical fitness level and a qualitative approach to training are recognized as protective factors against injury. Subsequent studies should investigate the specific predictors of injuries among referees

Correlation between Fitness and Fatness in 6-14-year Old Serbian School Children

Lack of physical activity and/or physical fitness are some reasons epidemiologists suggest for increase in childhood obesity in the last 20 years, with clear correlation between body composition and physical activity and/or physical fitness yet to be determined. The objectives of the study were to (a) investigate the prevalence of overweight and obesity among Serbian school children and (b) determine the relationship between indicators of physical activity and body fatness in Serbian school children aged 6-14 years. The study subjects included a representative sample of Serbian elementary school children (n=1, 121—754 boys and 367 girls—aged 6.2-14.1 years), all of whom were recruited in the OLIMP (Obesity and Physical Activity among Serbian School Children) study. Anthropometric and physical fitness values, including body mass index (BMI), waist-circumference, body-fat, and aerobic capacity, were measured in all the children. Significant differences were found between male and female children regarding the prevalence of obesity (6.8% vs 8.2%, p<0.05, boys and girls respectively). Boys had significantly lower body mass, BMI, waist-circumference, sum of six skinfolds, and body-fat compared to their female counterparts (p<0.05). The highest level of weight, BMI, body-fat, and waist-circumference observed in a 14-year old girl (96.3 kg, 40.5 kg/m2, 54.5%, 91.4 cm respectively) implies the existence of extreme obesity in Serbian school children. The negative relationship between body-fat and maximal oxygen (VO2max) uptake was moderately high (r=-0.76; p<0.05). The study has shown a high prevalence of adiposity among Serbian school children, with a strong negative relationship between aerobic fitness and body fatness. Data of the study emphasize the necessity to identify children with weight problems and to develop early interventions to improve physical activity in children and prevent the increase of childhood obesity

Primary percutaneous coronary intervention in a patient with right internal mammary artery graft originating from arteria lusoria dextra

Introduction Congenital anomalies of the aortic arch, although numerous and heterogeneous, occur in less than 1% of individuals at autopsies. Left aortic arch with an aberrant right subclavian artery, also called arteria lusoria dextra, is the most common anomaly of the aortic arch, occurring in 0.5-2.5% of individuals. Case Outline We report the case of a 48-year-old man suffering from acute inferoposterior-wall ST elevation myocardial infarction successfully treated by primary percutaneous coronary intervention. Ten years ago, the patient had undergone coronary artery bypass graft surgery with the implantation of two arterial grafts - left and right internal mammary arteries on both left anterior descending and right coronary artery. After several attempts to canulate truncus brachiocephalicus, angiogram revealed the left aortic arch with the aberrant right subclavian artery. To our knowledge, this is the first described case of primary percutaneous coronary intervention via the aberrant right subclavian artery and right internal mammary artery graft with stent implantation in the infarct related lesion of the distal segment of right coronary artery. Subsequent 64-multidetector computed tomography confirmed the angiographic findings. Conclusion Early recognition of congenital anomalies of the aortic arch and its great vessels, even before coronary artery bypass graft surgery, could be crucial for the urgent and successful treatment of patients with life-threatening conditions, such as ST segment elevation myocardial infarction

The effect of rapid weight loss on body composition and circulating markers of creatine metabolism in judokas

We evaluated the effects of a 7-day rapid weight loss (RWL) intervention on body composition and biomarkers of creatine metabolism in eight elite judokas during a pre-competition period. RWL induced a significant drop in weight (81.7±10.7 kg at baseline vs. 76.8 ± 10.3 kg at follow-up; p<.001), fat mass (12.6±5.6 kg vs. 9.2±4.0 kg; p=.003) and fat-free mass (69.1±7.3 kg vs. 67.6±7.7 kg; p=.05), accompanied by an increase in serum creatinine levels at follow-up (104.0±10.5 μmol/L vs. 114.9±10.2 μmol/L; p=.009). An acute restriction of food and fluid intake appears to negatively affect fat-free mass and indices of kidney function in judokas

A pilot study of transrectal endoscopic ultrasound elastography in inflammatory bowel disease

BACKGROUND: Using standard diagnostic algorithms it is not always possible to establish the correct phenotype of inflammatory bowel disease which is essential for therapeutical decisions. Endoscopic ultrasound elastography is a new endoscopic procedure which can differentiate the stiffness of normal and pathological tissue by ultrasound. Therefore, we aimed to investigate the role of transrectal ultrasound elastography in distiction between Crohn's disease and ulcerative colitis. ----- METHODS: A total 30 Crohn's disease, 25 ulcerative colitis, and 28 non-inflammatory bowel disease controls were included. Transrectal ultrasound elastography was performed in all patients and controls. In all ulcerative coltis patients and 80% of Crohn's disease patients endoscopy was performed to assess disease activity in the rectum. ----- RESULTS: Significant difference in rectal wall thickness and strain ratio was detected between patients with Crohn's disease and controls (p = 0.0001). CD patients with active disease had higher strain ratio than patients in remission (p = 0.02). In ulcerative colitis group a significant difference in rectal wall thickness was found between controls and patients with active disease (p = 0.03). A significant difference in rectal wall thickness (p = 0.02) and strain ratio (p = 0.0001) was detected between Crohn's disease and ulcerative colitis patient group. Crohn's disease patients with active disease had a significantly higher strain ratio compared to ulcerative colitis patients with active disease (p = 0.0001). ----- CONCLUSION: Transrectal ultrasound elastography seems to be a promising new diagnostic tool in the field of inflammatory bowel disease. Further study on a larger cohort of patients is needed to definitely assess the role of transrectal ultrasound elastography in inflammatory bowel disease
