Diabetes mellitus effect on rates of perioperative complications after operative treatment of distal radius fractures.

PURPOSE: This study focuses on distal radius fractures that require surgical treatment. Patients with diabetes mellitus (DM) are at increased risk of bone fracture despite normal areal bone mineral density. The aim of this study is to identify the impact of DM on perioperative complications for patients undergoing operative treatment of distal radius fracture. METHODS: A retrospective cohort study was conducted using data collected through the National Surgical Quality Improvement Program database. All patients who underwent operative treatments for distal radius fractures from 2007 through 2018 were identified. Data collected include demographic information, comorbidities, and complications occurring within 30 days of initial surgical intervention. The incidence of adverse events following surgery was evaluated with univariate and multivariate analyses where appropriate. RESULTS: Patients with DM were found to have a low rate of complications postsurgical repair of distal radius fractures. Preoperative comorbidity analysis showed that the diabetic group had significantly higher rates of chronic obstructive pulmonary disease, hypertension, congestive heart failure, renal failure, steroid use, bleeding disorders, dyspnea, and poorer functional status. Diabetes was found to be an independent predictor for unplanned intubation, sepsis, and septic shock. Diabetes was not found to be an independent predictor of other postoperative complications. CONCLUSION: Complications after surgical repair of distal radius fracture are low except when it comes to reintubation, sepsis, and septic shock. While the risks of independent complications remain relatively low, diabetes remains an important factor to consider when selecting surgical candidates and to ensure appropriate pre-operative risk assessment.

Efficacy of Arthroscopic Arthrolysis in the Treatment of Arthrofibrosis: A Systematic Review.

Stiffness after total knee arthroplasty (TKA) remains a clinical challenge for health care professionals. Historically, arthroscopic arthrolysis is a treatment modality that has been reserved for patients that have failed other conservative modalities, including manipulation under anesthesia. However, a systematic review of the literature evaluating the clinical efficacy and complications of arthroscopic arthrolysis for stiffness after TKA has not been performed. A systematic review of medical databases (PubMed, EMBASE, Cochrane Library) was undertaken for articles published from January 1980 to October 2018. A descriptive and critical analysis of the results was performed. From 1,326 studies, 7 studies met the inclusion criteria for this study. A total of 160 patients who underwent arthroscopic arthrolysis for arthrofibrosis following TKA were included for analysis. The quality of the evidence for the included studies ranged between moderate and high. Overall, patients had significant increased range of motion and flexion by 32.5 and 26.7 degrees, respectively following arthroscopic arthrolysis. Functional outcome scores also significantly improved for patients who underwent arthroscopic arthrolysis after TKA. Arthroscopic arthrolysis is an efficacious modality for treatment of stiffness following TKA. The greatest benefit is seen among patients that present with significant loss of flexion. Arthroscopic arthrolysis should be reserved for patients that have previously failed more conservative modalities.

Impact of Mesenchymal Stromal Cell Delivery Through Cardiopulmonary Bypass on Postnatal Neurogenesis.

BACKGROUND: Neurodevelopmental impairment is an important challenge for survivors after neonatal surgery with cardiopulmonary bypass (CPB). The subventricular zone, where most neural stem/progenitors originate, plays a critical role in cortical maturation of the frontal lobe. Promoting neurogenesis in the subventricular zone is therefore a potential therapeutic target for preserving cortical growth. Mesenchymal stromal cells (MSCs) promote endogenous regeneration in the rodent brain. We investigated the impact of MSC delivery through CPB on neural stem/progenitor cells and neuroblasts (ie, young neurons) in the piglet subventricular zone. METHODS: Two-week-old piglets (n = 12) were randomly assigned to one of three groups: (1) control, (2) deep hypothermic circulatory arrest, and (3) circulatory arrest, followed by MSC administration. MSCs (10 × 106 per kg) were delivered through CPB during the rewarming period. Neural stem/progenitors, proliferating cells, and neuroblasts were identified with immunohistochemistry at 3 hours after CPB. RESULTS: CPB-induced insults caused an increased proliferation of neural stem/progenitors (P < .05). MSC delivery reduced the acute proliferation. MSC treatment increased the number of neuroblasts in the outer region of the subventricular zone (P < .05) where they form migrating chains toward the frontal lobe. Conversely, the thickness of the neuroblast-dense band along the lateral ventricle was reduced after treatment (P < .05). These findings suggest that MSC treatment changes neuroblast distribution within the subventricular zone. CONCLUSIONS: MSC delivery through CPB has the potential to mitigate effects of CPB on neural stem/progenitor cells and to promote migration of neuroblasts. Further investigation is necessary to determine the long-term effect of MSC treatment during CPB on postnatal neurogenesis.

Why is applying to fellowship so difficult?

Students at all stages of their medical careers rely on the internet to research programs during the application process to help them learn and make educated decisions. In fact, studies with prospective emergency medicine residents have shown that the quality of information online can even impact an applicant decision to apply. Fellowship program information on institutional websites in the fields of pediatrics, orthopedics surgery, and sports medicine have been studied each highlighting poor content and accessibility of information within the domains of program information, application process and educational curriculum. In this call to action, we aim to shed light on the content and accessibility of information on Maternal Fetal Medicine (MFM) fellowship program websites and discuss the benefits of further centralizing and standardizing program information.
