Does rural residence impact total ankle arthroplasty utilization and outcomes?
The objective of this study was to compare total ankle arthroplasty (TAA) utilization and outcomes by patient residence. It demonstrated an absence of any evidence of rural-urban differences in TAA outcomes. The rural-urban differences in TAA utilization noted in 2003 were no longer significant in 2011.

Serum urate gene associations with incident gout, measured in the Framingham Heart Study, are modified by renal disease and not by body mass index.
The researchers hypothesized that serum urate-associated SNPs, individually or collectively, interact with BMI and renal disease to contribute to risk of incident gout. They measured the incidence of gout and associated comorbidities using the original and offspring cohorts of the Framingham Heart Study. They demonstrated that minor alleles of rs1106766 (intergenic, INHBC) were negatively associated with the risk of incident gout in subjects without renal disease, but not for individuals with renal disease.

Time trends in total ankle arthroplasty in the USA: a study of the National Inpatient Sample.
The objective of this study was to assess the time trends in utilization, clinical characteristics, and outcomes of patients undergoing total ankle arthroplasty (TAA) in the USA. It concluded that the utilization rate of TAA increased rapidly in the USA from 1998 to 2010, but post-arthroplasty mortality rate was stable. Underlying diagnosis and medical comorbidity changed over time and both can impact outcomes after TAA.

Are outcomes after total knee arthroplasty worsening over time? A time-trends study of activity limitation and pain outcomes.
The authors examined whether function and pain outcomes of patients undergoing primary total knee arthroplasty (TKA) are changing over time. Using Mayo Clinic Total Joint Registry data, they found that patient-reported function and pain outcomes after primary TKA have worsened over the study period 1993-95 to 2002-05; this time-trend is independent of changes in preoperative pain/limitation and certain patient characteristics.

Trends in elective labor induction for six United States health plans, 2001-2007.
The authors sought to describe trends in labor induction, including elective induction, from 2001 to 2007 for six U.S. health plans and to examine the validity of induction measures derived from birth certificate and health plan data. They found that induction prevalence rose from 28% in 2001 to 32% in 2005, then declined to 29% in 2007, with the trend being similar for subgroups by parity and gestational age. Elective induction prevalence varied considerably across plans.
