Association between metformin use and progression of monoclonal gammopathy of undetermined significance to multiple myeloma in US veterans with diabetes mellitus: a population-based retrospective cohort study.
The authors assessed the association between metformin use and progression of monoclonal gammopathy of undetermined significance to multiple myeloma. They found that metformin use was associated with a reduced risk of progression to multiple myeloma.

Outcomes of carotid endarterectomy versus stenting in comparable medical risk patients.
The purpose of this study was to compare risk-stratified outcomes of carotid artery stenting (CAS) and carotid endarterectomy (CEA). Included in the study group were 11,336 patients who underwent isolated primary CEA and 544 who underwent primary CAS. The researchers found that asymptomatic normal- and high-risk patients do equally well after CEA or CAS. However, normal- and high-risk symptomatic patients have substantially worse outcomes with CAS compared with CEA.

The impact of short breaks from cardiac surgery on mortality and stay length in California.
In this small, exploratory study, the researchers sought to investigate potential surgical “forgetting” among cardiac surgeons taking a break from performing isolated coronary artery bypass graft (CABG) surgery in a large state-wide study in California. Patients operated on by surgeons who had not performed isolated CABG in the prior calendar month stayed in hospital 0.5 day longer.

Gender differences in composite control of cardiovascular risk factors among patients with type 2 diabetes.
This study examined the gender differences in multiple cardiovascular disease (CVD) risk factor control in adults with type 2 diabetes seen in diverse clinical settings. It found that women had significantly poorer composite control of CVD risk outcomes compared with men, adjusting for relevant confounding factors. In unadjusted analyses, women had higher mean systolic blood pressure and LDL cholesterol levels compared with men.

Safety of intravenous tissue plasminogen activator administration with computed tomography evidence of prior infarction.
The researchers sought to determine if the presence of a previous stroke on pretreatment computed tomography (CT) is a predictor of hemorrhagic complications and functional outcomes after the administration of intravenous (IV) tissue plasminogen activator (tPA). Their data suggest that a prior stroke on CT should not be viewed as a reason to withhold this treatment unless it occurred within the last 3 months.

Are articular cartilage lesions and meniscus tears predictive of IKDC, KOOS, and Marx activity level outcomes after anterior cruciate ligament reconstruction? A 6-year multicenter cohort study.
This study of 1,512 ACLR patients who were followed for 6 years found that both articular cartilage injury and meniscus tears/treatment at the time of ACLR were significant predictors of International Knee Documentation Center (IKDC) and Knee injury Osteoarthritis Outcome Score (KOOS) scores after ACLR. Having a grade 4 medial femoral condyle lesion significantly reduced a patient’s Marx activity level score at 6 years.

Long-term outcomes of vaginal mesh versus native tissue repair for anterior vaginal wall prolapse.
This study estimated the rate of repeat surgery after vaginal mesh versus native tissue repair for anterior vaginal wall prolapse. The researchers found that the overall risk of any future surgery was higher in the women receiving mesh; however, native tissue and vaginal mesh surgery had similar 5-year risks for recurrent prolapse.
