Observed Injury Rates Did Not Follow Theoretically Predicted Injury Risk Patterns in Professional Human Circus Artists.

Objective: Identifying which types of athletes have increased injury risk (ie, predictive risk factors) should help develop cost-effective selective injury prevention strategies. Our objective was to compare a theoretical injury risk classification system developed by coaches and rehabilitation therapists, with observed injury rates in human circus acts across dimensions of physical stressors, acrobatic complexity, qualifications, and residual risks.

Design: Descriptive epidemiological study.

Pulmonary function tests as outcomes for systemic sclerosis interstitial lung disease.

Interstitial lung disease (ILD) is the leading cause of morbidity and mortality in systemic sclerosis (SSc). We performed a systematic review to characterise the use and validation of pulmonary function tests (PFTs) as surrogate markers for systemic sclerosis-associated interstitial lung disease (SSc-ILD) progression.Five electronic databases were searched to identify all relevant studies.

Enteric disease episodes and the risk of acquiring a future sexually transmitted infection: a prediction model in Montreal residents.

Objective: The sexual transmission of enteric diseases poses an important public health challenge. We aimed to build a prediction model capable of identifying individuals with a reported enteric disease who could be at risk of acquiring future sexually transmitted infections (STIs).

Materials And Methods: Passive surveillance data on Montreal residents with at least 1 enteric disease report was used to construct the prediction model.

Comparison of different measures of diffusing capacity for carbon monoxide (DLCO) in systemic sclerosis.

In systemic sclerosis (SSc), impaired diffusing capacity for carbon monoxide (DLCO) can indicate interstitial lung disease (ILD), pulmonary hypertension (PH), and/or other disease manifestations, including anemia. We undertook this study to compare the various measures of DLCO in the setting of a complex disease like SSc. We analyzed the pulmonary function tests of a cohort of SSc subjects, as a whole and among subjects with isolated PH and ILD separately.

Longitudinal study of renal function in systemic sclerosis.

Objective: To determine the prevalence of renal disease and the course of renal function over time in patients with systemic sclerosis (SSc).

Methods: We performed a multicenter, longitudinal study of 561 patients with SSc followed in the Canadian Scleroderma Research Group registry. Renal function was measured by the estimated creatinine clearance rate (eCcr) using the Cockcroft-Gault formula.
