ABSTRACT
ObjectiveTo utilize publicly reported, state-level data to identify factors associated with the frequency of cases, tests, and mortality in the US. Materials & MethodsRetrospective study using publicly reported data collected included the number of COVID-19 cases, tests, and mortality from March 14th through April 30th, 2020. Publicly available state-level data was collected which included: demographics comorbidities, state characteristics and environmental factors. Univariate and multivariate regression analyses were performed to identify the significantly associated factors with percent mortality, case and testing frequency. All analyses were state-level analyses and not patient-level analyses. ResultsA total of 1,090,500 COVID-19 cases were reported during the study period. The calculated case and testing frequency were 3,332 and 19,193 per 1,000,000 patients. There were 63,642 deaths during this period which resulted in a mortality of 5.8%. Factors including to but not limited to population density (beta coefficient 7.5, p< 0.01), transportation volume (beta coefficient 0.1, p< 0.01), tourism index (beta coefficient -0.1, p=0.02) and older age (beta coefficient 0.2, p=0.01) are associated with case frequency and percent mortality. ConclusionsThere were wide variations in testing and case frequencies of COVID-19 among different states in the US. States with higher population density had a higher case and testing rate. States with larger population of elderly and higher tourism had a higher mortality. Key MessagesThere were wide variations in testing and case frequencies of COVID-19 among different states in the US. States with higher population density had a higher case and testing rate. States with larger population of elderly and higher tourism had a higher mortality.
ABSTRACT
BACKGROUND: The Targon FN implant was developed in 2007 to treat intracapsular neck of femur fractures. Early results from the design centre have shown good results in terms of fracture complications. We wished to see if these results can be reproduced in an independent institution. METHODS: The records of consecutive patients, treated with this implant between 2008 and 2011 at Queen Elizabeth Hospital, were identified and collected for this study. Operations were performed by all grades of surgeons under supervision as appropriate. These patients went on to have both clinical and radiological assessment for fracture healing and function. RESULTS: Fifty-one patients were identified with 43 patients available for final follow-up. The average age was 66 years with a minimum follow-up of 24 months. A non-union rate of 0% in the undisplaced fracture group and 1 in 12 (8%) in the displaced fracture group was observed. An avascular necrosis rate of 6% and 8% was observed for undisplaced and displaced fracture types, respectively. No significant change in premorbid to postoperative ambulation was observed and there was no wound complication. CONCLUSIONS: Our study shows similar results with those of the design centre and which are superior to those currently found in the literature for the more traditional fixation methods. It also shows that the promising results with this new implant as seen from the design institutions can be reproduced by all cadres of surgeons in non-specialist practice.
