RESUMEN
BACKGROUND: Acute Charcot Neuroarthropathy (CN) is a destructive condition that is characterised by acute fractures, dislocations and joint destruction in the weight-bearing foot. The acute phase is often misdiagnosed and can rapidly lead to devastating health outcomes. Early diagnosis and management of CN is imperative to attenuate progression of this condition. Consequently, timely evidence-based assessment, diagnosis and management of acute CN is imperative. OBJECTIVE: To identify the factors that impact the delivery of evidence-based care in assessment, diagnosis and management of people with acute CN. METHOD: Systematic searches were conducted in four databases to identify studies in English that included factors that impact the delivery of evidence-based care in the assessment, diagnosis and management of people with acute CN. Articles and consensus/guideline documents were assessed for inclusion by the researchers and disagreements were resolved through consensus. Additionally backward citation searching was used to source other potentially relevant documents. Information relevant to the research question was extracted and thematic analyses were performed using qualitative synthesis. RESULTS: Thirty-two articles and four additional consensus/guideline documents were included for data extraction and analyses. Information related to the research question was of expert opinion using the National Health and Medical Research Council (NHMRC) Levels of Evidence guidelines. Themes explaining practices that deviated from evidence-based care in assessment, diagnosis and management of acute CN centred around patient, health professional and health organisation/environmental. Delay to diagnosis is particularly influenced by the patient's knowledge of when to seek help, practitioner knowledge in knowing how to recognise and refer for appropriate immediate care, confusion in imaging and offloading and geographical and local health service resources to appropriately manage the condition. CONCLUSION: Individual and health professional awareness and geographical barriers are key challenges to the effective delivery of evidence-based assessment, diagnosis and management of people with acute CN. Acute CN represents a medical emergency warranting the need for expedited assessment, diagnosis and management by appropriately trained health professionals in the appropriate.

To compare the glycemic and metabolic responses to simulated intermittent games activity and continuous running exercise in type 1 diabetes. Nine patients (seven male, two female; 35 ± 4 years; HbA1c 8.1 ± 0.2%/65 ± 2 mmol/mol) treated on a basal-bolus regimen completed two main trials, a continuous treadmill run (CON) or an intermittent running protocol (INT). Patients arrived to the laboratory fasted at â¼ 08:00 h, replicating their usual pre-exercise meal and administering a 50% reduced dose of rapid-acting insulin before exercising. Blood glucose (BG), K(+) , Na(++) , pH, triglycerides, serum cortisol and NEFA were measured at baseline and for 60 min post-exercise. Interstitial glucose was measured for a further 23 h under free-living conditions. Following exercise, BG declined under both conditions but was less under INT (INT -1.1 ± 1.4 vs CON -5.3 ± 0.4 mmol/L, P = 0.037), meaning more patients experienced hypoglycemia (BG ≤ 3.5 mmol/L; CONâ n = 3 vs INTâ n = 2) but less hyperglycemia (BG ≥ 10.9 mmol/L; CONâ n = 0 vs INTâ n = 6) under CON. Blood lactate was significantly greater, and pH lower, with a temporal delay in K(+) under INT (P < 0.05). No conditional differences were observed in other measures during this time, or in interstitial glucose concentrations during the remaining 23 h after exercise. Simulated games activity carries a lower risk of early, but not late-onset hypoglycemia than continuous running exercise in type 1 diabetes.

To analyse the effect of exercise-based rehabilitation programs for improving lower limb muscle strength in individuals with hip or knee osteoarthritis (OA). A systematic search utilizing seven databases identified randomized controlled trials (RCTs) evaluating lower limb strength outcomes of exercise-based interventions for participants with hip or knee OA. All studies were screened for eligibility and methodological quality. Quality of evidence was assessed using Grading of Recommendation, Assessment, Development and Evaluation (GRADE) approach. Data were pooled and meta-analyses performed where appropriate. Forty RCTs were included and the majority (77%) involved resistance based exercise programs. For knee OA populations, there was high quality evidence for improved knee extension (standardized mean difference (SMD) = 0.47, 95% confidence intervals (CI) 0.29, 0.66) and flexion strength (SMD = 0.74, 95% CI 0.56, 0.92) with low-intensity resistance program when compared to a control at short term (ST) follow-up. There was moderate quality evidence for a large effect favouring high-intensity resistance programs (SMD = 0.76, 95% CI 0.47, 1.06) when compared to a control. This effect was sustained at intermediate term (IT) follow-up (SMD = 0.80, 95% CI 0.44, 1.17). Few studies reported on outcomes at long term (LT) follow-up. Only one study reported on a population with hip OA. When compared to a control group, high-intensity resistance exercise demonstrated moderate quality of evidence for large and sustained improvements for knee muscle strength in knee OA patients. Further work is needed to compare different modes of exercise at a LT follow-up for knee OA patients and to address the dearth of literature evaluating exercise interventions in people with hip OA.

Various regulatory mechanisms of pulmonary oxygen uptake (VÌO2) kinetics have been postulated. The purpose of this study was to investigate the relationship between vagal withdrawal, measured using RMSSDRR, the root mean square of successive differences in cardiac interval (RR) kinetics, a mediator of oxygen delivery, and VÌO2 kinetics. Forty-nine healthy adults (23 ± 3 years; 72 ± 13 kg; 1.80 ± 0.08 m) performed multiple repeat transitions to moderate- and heavy-intensity exercise. Electrocardiography, impedance cardiography, and pulmonary gas exchange parameters were measured throughout; time domain measures of heart rate variability were subsequently derived. The parameters describing the dynamic response of VÌO2, cardiac output (Q) and RMSSDRR were determined using a mono-exponential model. During heavy-intensity exercise, the phase II τ of VÌO2 was significantly correlated with the τ of RR (r = 0.36, P < 0.05), Q (r = 0.67, P < 0.05), and RMSSDRR (r = 0.38, P < 0.05). The τ describing the rise in Q explained 47% of the variation in VÌO2 τ, with 30% of the rate of this rise in Q explained by the τ of RR and RMSSDRR. No relationship was evident between VÌO2 kinetics and those of Q, RR, or RMSSDRR during moderate exercise. Vagal withdrawal kinetics support the concept of a centrally mediated oxygen delivery limitation partly regulating VÌO2 kinetics during heavy-, but not moderate-, intensity exercise.
