there are increasing numbers of veterans with TBIs and stress and that these veterans may develop AD late in life if no appropriate therapeutic intervention is available. IMPLICATIONS Per these published reports, the fact that TBIs and psychological stress can accelerate the pathogenesis of AD should be recognized. Active military personnel, veterans, and their close family members should be evaluated regularly for stress symptoms to prevent the pathogenesis of neurodegenerative diseases, including AD. Introduction Reverse neurocutaneous and propeller perforator flaps are both used to reconstruct diabetic distal lower limb defects. Our study aims to compare outcomes between these two groups of flaps with an emphasis on indications and complication rates. Method A retrospective analysis was conducted, reviewing data from 54 diabetic patients who underwent reconstruction of acute or chronic wounds of the foot and ankle between 2005-2018. Thirty-four patients (Group A) had a reverse neurocutaneous flap (NCF) nineteen sural and fifteen lateral supramalleolar flaps. Twenty patients (Group B) had a propeller flap (PF) based on peroneal (n = 13) or posterior tibial artery perforators (n = 7). All patients had a preoperative Doppler examination to identify the nutrient artery of the flap. In both groups, we recorded patients' demographics, characteristics of the defect, postoperative complications and time to heal. Follow-up ranged from 6 to 59 months. Student's t-test and chi-squared test were used for statisticalurocutaneous flaps are specially indicated for larger and more distally located defects, although they might be associated with longer healing time and additional revision surgeries. Propeller flaps were more frequently used in younger patients for smaller and more proximally located defects. INTRODUCTION The gold-standard surgical procedure of both-bone forearm shaft fracture repair is elastic stable intramedullary nailing (ESIN). Disadvantages effects of ESIN have suggested to be a consequence of inappropriate surgical techniques, while recommendations are not always followed. The purpose of the study was to analyze the effect of inadequate metal frame construct on impaired fracture healing, refracture and changing alignment. MATERIALS AND METHODS It is a population-based study including all consecutive patients, aged less than 16 years, who had been treated for forearm shaft fracture by ESIN during the ten-year period 2009-2018. Altogether 71 patients were included. Non-union, delayed union, and re-fracture during the following 12 months were taken as the main outcome, while inferior metal frame construct of ESIN and the surgical technique characteristics were taken the explanatory factors. Radiographic loss of reduction was a secondary outcome and a change >5° in alignment at any postoperativen the vast majority (90%) of the patients and completely perfect metal frame construct was not required. With graphene oxide (GO), platinum carbon (Pt/C), and reduced graphene oxide (rGO) as cathode catalysts, three types of single-chamber microbial fuel cells (MFCs) were constructed for simultaneous Cu2+ removal and electricity production. https://www.selleckchem.com/products/3-deazaneplanocin-a-dznep.html Results indicated rGO-MFC and Pt/C-MFC had much better Cu2+-removing and electricity-generating performance than that of GO-MFC, and rGO-MFC presented preferable electrochemical characteristics compared with Pt/C-MFC. Microbial community analysis indicated Geobacter dominated anodic biofilms and was mainly responsible for organics degradation and electricity generation. The dual bio-selective effects by cathode catalyst and toxic Cu2+ resulted in different cathodic microbial communities. At high Cu2+ contents, Nitratireductor, Ochrobactrum, and Serratia as efficient Cu2+-removing genera played key roles in Pt/C-MFC, and Azoarcus predominant in cathodic biofilms of rGO-MFC might be important contributor for the favorable performance in this case. INTRODUCTION Patient age has been intermittently associated with demographics and outcomes in cutaneous melanoma. We looked at the association of age and patient demographics, tumor features, and melanoma-related outcomes in patients undergoing sentinel lymph node (SLN) biopsy for melanoma. METHODS We reviewed demographics (age, gender), tumor features (mean Breslow thickness, ulceration, SLN positivity rates), and outcomes (all-site relapse, progression to stage IV, death from melanoma, complications) from a university-based prospective database of 1633 patients. Patients were grouped by decade of age and the impact of age was examined by univariable and multivariable analyses. RESULTS Increasing age was directly associated with number of patients referred for SLN biopsy, male gender, head and neck (H&N) tumor location, mean Breslow thickness, tumor ulceration, and with all -site relapse, progression to stage IV, death from melanoma and complication rates. Increasing age was indirectly associated with SLN positivity rates. Comparing ages 60, these trends reached statistical significance for male gender, H&N location, SLN positivity, all-site relapse, progression to stage IV (development of metastases) and death from melanoma. CONCLUSIONS Referrals for SLN biopsy increase with increasing patient age, yet increasing age is associated with lower SLN positivity rates. This occurs despite the fact that older patients have thicker, more ulcerated tumors, and higher melanoma-related relapse and death rates. BACKGROUND A gender pay gap has been reported across many professions, including medicine. METHODS Surgeons employed at complex Veterans Affairs Medical Centers (VAMC) nationwide in 2016 were identified. Data on salary, gender, years since medical school graduation, professorship status, h-index, and geographic location were collected. RESULTS Of 1993 surgeons nationwide, 23% were female. On average, female surgeons had significantly lower salaries compared to male surgeons ($268,429 ± 41,339 versus $287,717 ± 45,379, respectively; p less then 0.001). Among each surgical specialty, there were no significant differences in salary on univariate analysis. Women were underrepresented in higher paying specialties and more heavily represented in lower paying specialties. On multivariate analysis, gender (p less then 0.001), time since medical school graduation (p less then 0.001), surgical specialty (p = 0.031), h-index (p less then 0.001), and geographic location (p less then 0.001) were significant predictors of salary.
