Beneficial miR-21 Silencing Reduces Heart failure Fibrosis along with Modulates Inflammatory Reaction inside Chronic Chagas Illness.
The complication rates were as follows dislocations, 19 (0.72%); DVT, 12 (0.45%); fractures, 13 (0.49%); infections, 49 (1.85%); and nerve injuries, 11 (0.42%). These findings demonstrate the anterior approach to THA has very low complication rates and acceptably low rates of infection. In addition, the minimally invasive THA has an acceptably low duration and a substantially reduced length of stay compared with more traditional THA approaches. [Orthopedics. 2020;43(x)xx-xx.].

Although other studies have examined these trends using a sampling of common orthopedic procedures compared with non-orthopedic specialties, robust examination across all orthopedic specialties is not available in the current literature. This study aimed to critically analyze the trends in reimbursement in the field of orthopedic surgery. Inflation-adjusted Medicare reimbursement and work relative value units (RVUs) between 2000 and 2016 for more than 200 individual Current Procedural Terminology codes across all major orthopedic subspecialties were analyzed, and inherent value of work RVUs was assessed by dividing reimbursement dollar values by work RVUs annually and tracking the changes. Between 2000 and 2016, reimbursement decreased across all orthopedic subspecialties by an average of 29%, except oncology, which showed a 6% increase. Work RVUs increased by an average of 10%, but the inherent value of work RVUs decreased across all orthopedic subspecialties by an average of 39%. Increased active involvement of orthopedic attending physicians and residents in coding documentation and fee-schedule representation is needed. [Orthopedics. 2020;43(x)xx-xx.].

Although this association has been shown in other surgical disciplines, it has not been demonstrated in patients undergoing TKA. This study was undertaken to determine whether patients with a PFO would have a significantly increased risk of cerebrovascular accident (CVA) following TKA. The Humana national database was used to identify TKA patients who were stratified by the presence of a PFO from 2007 to 2016. Ninety-day follow-up was used for the primary outcome of CVA. Potential confounding comorbidities also were investigated, including age, sex, anticoagulation, insurance type, arrhythmia, valvular disease, peripheral vascular disease, chronic kidney disease, and diabetes mellitus. Of 153,245 TKAs, a total of 2272 patients had strokes; 479 of these patients had a PFO. On multivariable analysis, PFO remained an independent predictor of CVA postoperatively (odds ratio, 3.824; 95% confidence interval, 2.614-5.406; P less then .0001). Other significant comorbidities associated with CVA included arrhythmia, chronic kidney disease, diabetes mellitus, peripheral vascular disease, and coronary valve disease. Importantly, low-molecular weight heparin or factor Xa inhibitor administration postoperatively had a negative correlation with stroke (odds ratio, 0.762; 95% confidence interval, 0.663-0.871; P=.0001 and odds ratio, 0.749; 95% confidence interval, 0.628-0.885; P=.0009, respectively). The findings of the multivariable analysis indicate PFO is associated with early postoperative CVA within 90 days following TKA. If known preoperatively, appropriate referral should be made to a cardiologist for PFO management and anticoagulation to reduce the overall risk of stroke. [Orthopedics. 2020;43(x)xx-xx.].

Published studies have mainly come from trauma centers with a young cohort of patients. The purpose of this study was to determine the nonunion rate of humeral shaft fractures in patients older than 55 years. A retrospective study was performed on a group of orthopedic trauma group treated at a level I trauma center during a 10-year period (2007-2017). Patients 55 years or older and treated for a humeral shaft fracture nonoperatively, with or without manipulation, were identified. Nonunion was defined by no bridging callus radiographically or by gross motion at the fracture at least 12 weeks from injury. There were 31 patients identified with humeral shaft fractures who met the inclusion criteria. The cohort included 21 (67.7%) females and 10 (32.3%) males with a mean age of 72.5 years (range, 55-92 years). Twenty-one fractures went on to union, and there were 10 nonunions, with no significant differences in the demographics or comorbidities. There was no correlation between AO/OTA fracture classification or fracture location and union status. There was a tendency toward higher risk of nonunion in proximal third humeral shaft fractures (45%) compared with middle (26%) and distal third (20%) humeral shaft fractures, although this was not statistically significant. The overall nonunion rate for humeral shaft fractures was 32% for patients older than 55 years. The authors found a significant correlation between age and union rate as age increased, union rate decreased (R=-0.9, P=.045). The incidence of humeral shaft nonunion in patients older than 55 years was significantly higher than that of younger adults. To the authors' knowledge, this study is the first to report a significant correlation between nonunion and increased age. [Orthopedics. 2020;43(x);xx-xx.].

No previous study has described the dimensions of this fossa. All cases using a lateral distal fibular plate for a fibula fracture from December 2012 to December 2015 (n=365) at a single institution were reviewed. Screws that violated the medial fibular cortical density corresponding to the MF were identified as "at-risk" screws. Available preoperative computed tomography (CT) scans were reviewed (n=69) to measure MF dimensions. Of 365 patients, 115 (31.5%) patients had distal fibular screws at risk of MF violation. There were no significant differences between MF violation and non-violation groups in terms of age, sex, open fracture, syndesmotic fixation, and Weber classification. The MF dimensions were measured on CT scans. Mean height was 12.96 mm (SD, 2.09 mm; range, 9.0-17.3 mm). Mean width was 7.52 mm (SD, 1.37 mm; range, 4.2-10.4 mm). Mean depth was 8.32 mm (SD, 1.59 mm; range, 5.
