Abstract
BackgroundBiomechanical stress is a prerequisite for OA development and studies have shown a difference in the effect of impact- and shear stress2, although studies of the direct impact of exercise on cartilage turnover have not demonstrated clear trends1.ObjectivesExploring how weight-bearing (WB), non-weight-bearing (NWB) exercise and cardiovascular stress influence circulating biomarkers of cartilage extracellular matrix turnover in OA.MethodsEFEX-OA-02 was a randomized, cross-over, clinical study investigating the direct effect of exercise on joint biomarkers in knee OA. Subjects were randomized to an order of cycling and running followed by adrenaline infusion and finally resting one week apart. Exercise and infusion sessions were multiphasic, consisting of 4x5-minute intervals. Peak cardiorespiratory stress (PCS) per interval was set to ≥80% of the heart rate reserve during exercise. Blood samples were obtained before, during, at five time points after and 24 h post exercise/infusion. For adrenaline infusion, 0.06 mg/kg of adrenaline was prepared in a 50 mL saline solution and administered intravenously. At rest, samples were collected at corresponding time points, except for the 24 h sample, which was omitted. Levels of serum C2M, T2CM (type II collagen degradation) and PRO-C2 (type II collagen formation) were measured using ELISA-assays (Nordic Bioscience). Coll2-1 and Coll2-1NO2 (type II collagen degradation) were measured using ELISA (Artialis).Changes in biomarker concentrations after activity were compared to baseline (BL) and the corresponding resting samples. We used ANCOVA and Dunnett’s test with geometric means of change from BL up to 240 min as the dependent variable and subject and activity as covariates. Paired t-test was used to compare values at 24-hour to BL.ResultsForty subjects were included. Mean age was 60.4 years (SD: 8.7), 24 (60%) were females, mean BMI was 27.0 kg/m2 (SD: 3.5), 18 had cumulated KL grade of 2 or 3 (45%) and 22 (55%) had KL 4, 5 or 6. and mean KOOS pain at BL was 67.5 (SD: 15.2) corresponding to mild-moderate pain. All subjects reached minimum PCS during exercise, but only an average of 70% (SD: 8.7) of that during infusion.Cycling induced a small reduction in C2M (peak: -5.3%, 95%CI: -7.8 to -2.7%). PRO-C2 increased rapidly in response to cycling (peak: 11.7%, 95%CI: 4.3 to 19.1%) and running (peak: 12.9%, 95%CI: 3.54 to 22.2%). T2CM decreased up to one hour after cycling (peak: -10.8%, 95%CI: -15.1 to -6.5%) and running (peak: -9.5%, 95%CI: -15.5 to -3.6%), similar to adrenaline, then increased. Coll2-1NO2 increased rapidly following cycling (peak: 12.5%, 95%CI: 2.8 to 22.2%) and running (peak: 9.8%, 95%CI: 0.26 to 19.6%). Trends of increase was found in Coll2-1 (21.3%, 95%CI: 2.9 to 39.6) and Coll2-1NO2 (11.6%, 95%CI: -7.9 to 31.1%) in response to running at 240 min (Figure 1 – Error bars: SE, *Change to resting, †Change from BL, */†: P < 0.05, **/††: P < 0.01 ***/†††: P<0.001).Figure 1.At 24h PRO-C2 reduced -9.4% (95%CI: -18.2 to -0.5%) after cycling, Coll2-1NO2 reduced -8.33% (95%CI: -17.0 to 0.3%) after running and T2CM elevated by 6.0% (95%CI: -0.8 to 12.8%) after running and 7.1% (95%CI: 0.5 to 13.7%) after cycling.ConclusionRunning, cycling and adrenaline infusion induced rapid small-to-moderate changes in circulating biomarkers reflecting type II collagen turnover. Changes after adrenaline-infusion suggests a cardiovascular contribution to exercise-induced changes. This model could potentially be used to evaluate treatment effects on collagen turnover.References[1]Bjerre-Bastos JJ, Karsdal MA, Boesen M, Bliddal H, Bay-Jensen A, Andersen JR, Bihlet AR: The acute and long-term impact of physical activity on biochemical markers and MRI measures in osteoarthritis—Perspectives for clinical osteoarthritis research.

Abstract
OBJECTIVE With ongoing national concern about food security, the aim of the study was to estimate the prevalence of food insecurity and to identify associated characteristics in a cohort of older Australians. DESIGN, SETTING AND PARTICIPANTS The Blue Mountains Eye Study is a cohort study of community living participants aged 49 + years. The 12-item food security survey was completed by 3068 participants in the cross sectional study which comprised 2335 survivors from baseline and the recruitment of an additional 1174 eligible residents. MAIN OUTCOME MEASURES Prevalence of self reported food insecurity was calculated and multivariate logistic regression provided odds ratios with 95% confidence intervals to determine risk factors. RESULTS Overall prevalence of food insecurity was 13%. Women (15.7%) compared with men (9.4%) and younger participants, aged <70 years (15.7%) than older participants, ≥70 years (8.4%), were significantly more likely to report being food insecure. Characteristics for reporting food insecurity included participants living in rented accommodation (OR 4.10, 95% CI: 2.83, 5.89) and those living on a pension only (OR 1.90, 95%CI: 1.30, 2.78). CONCLUSIONS A relatively high level of food insecurity among this representative population of older Australians should be an issue of concern for policy makers and health and welfare service providers. Addressing food insecurity should be a priority of integrated national food and nutrition policies and this should in turn inform health and welfare service provision to this vulnerable population.

Abstract
The first meeting of international specialists in the field of von Willebrand disease (VWD) was held in the Åland islands in 1998 where Erik von Willebrand had first observed a bleeding disorder in some members of a family from Föglö and a summary of the meeting was published in 1999. The second meeting was held in 2010 and a report of the meeting was published in 2012. Topics covered included progress in understanding of VWD over the last 50 years; multimers; classification of VWD; pharmacokinetics and laboratory assays; genetics; treating the paediatric patient; prophylaxis; geriatrics; gene therapy and treatment guidelines. This third meeting held over 3 days covered the structure and function of von Willebrand factor (VWF); type 1 VWD, the most common form of the disease; a lifespan of pharmacokinetics in VWD; detecting inhibitors in VWD patients; and special challenges in understanding and treating the female VWD patient.

Abstract
The combination of ventricular tachycardia (VT) and severe left ventricular dysfunction presents a serious challenge in management of acute fulminant myocarditis (AFM). We report a case of a 17-month-old girl with AFM, presented with hypotension and VT, successfully treated with respiratory and inotropic support, high-dose intravenous immunoglobulin, and amiodarone. The myocardial function improved significantly within 2 weeks of treatment. The clinical course was complicated by significant amiodarone-induced hepatotoxicity, disseminated intravascular coagulation, and deep-vein thrombosis. She was later diagnosed with congenital dysfibrinogenemia and treated with chronic Lovenox therapy.

Abstract
AIM To determine the prevalence of thyroid disease in an older Australian population in a population-based cross-sectional study. BACKGROUND Community-living subjects, aged 49 years or older, in two Blue Mountains postcodes were invited to participate in an eye, nutrition and health study between 1997 and 2000. METHODS Three thousand five hundred and nine of the 4489 identified persons participated. Fifty-seven per cent of 3504 who completed questionnaires were women; their mean age was 66.8 years. Thyroid-stimulating hormone (TSH) was measured in 2665 subjects (76% of those completing the questionnaire). The main outcome measures were serum TSH and free thyroxine levels, serum lipids, urate and sugar levels and questionnaire responses. RESULTS The prevalence of recognized thyroid disease (either self-reported history of thyroid disease or current thyroxine treatment) was 10% (95% confidence interval (CI) 8.9-11.1%). An additional 3.6% (95%CI 2.9-4.3%) of participants had unrecognized thyroid disease (abnormal TSH). The TSH was abnormal in 7.1% (95%CI 5.8-8.4%) of women and 3.7% (95%CI 2.6-4.8%) of men. Sixty-five per cent of those with an abnormal TSH did not report a history of thyroid disease, whereas 25% of those taking thyroxine replacement therapy had an abnormal TSH level. The prevalence of hypothyroidism increased with increasing age in women. The mean fasting cholesterol was 0.36 mmol/L (95%CI 0.15-0.57) higher in hypothyroid subjects than in euthyroid subjects. CONCLUSION Thyroid disease in older Australian women is relatively common and may be undiagnosed. Ongoing monitoring of patients on thyroxine replacement therapy is important, given that 25% of treated patients had an abnormal TSH.

Abstract
OBJECTIVE To examine the validity of self-reported height and weight data reported over the telephone in the 1997 NSW Health Survey, and to determine its accuracy to monitor overweight and obesity in population surveys. METHOD Self-reported and measured heights and weights were collected from 227 people living in Western Sydney, who had participated in the NSW Health Survey 1997. RESULTS Self-reported (SR) weights and heights led to misclassification of relative weight status. BMI, based on measured weights and heights, classified 62% of males and 47% of females as overweight or obese, compared with 39% and 32%, respectively, from self-report. CONCLUSIONS Caution should be used when interpreting SR height and weight data from surveys, because BMI derived from these is likely to underestimate the true prevalence of overweight and obesity. IMPLICATIONS SR data have a place in nutrition monitoring because they are relatively inexpensive and easy to collect. However, classifying people into weight categories on the basis of accepted cut-points, using SR heights and weights, yields inaccurate prevalence estimates. Periodic sub-studies of the validity of SR heights and weights are needed to indicate the extent to which the validity of SR is changing.
