BACKGROUND To assess the impact of living liver donation (LD) in a diverse and aging population up to 20 y after donation, particularly with regard to medical, financial, psychosocial, and overall health-related quality of life (HRQOL). METHODS Patients undergoing LD between 1999 and 2009 were recruited to respond to the Short-Form 36 and a novel Donor Quality of Life Survey at two time points (2010 and 2018). RESULTS Sixty-eight living liver donors (LLDs) completed validated surveys, with a mean follow-up of 11.5 ± 5.1 y. Per Donor Quality of Life Survey data, physical activity or strength was not impacted by LD in most patients. All respondents returned to school or employment, and 82.4% reported that LD had no impact on school or work performance. LD did not impact health insurability in 95.6% of donors, and only one patient experienced difficulty obtaining life insurance. Overall, 97.1% of respondents did not regret LD. Short-Form 36 survey-measured outcomes were similar between LLDs and the general U.S. POPULATION LLDs who responded in both 2010 and 2018 were followed for an overall average of 15.4 ± 2.4 y and HRQOL outcomes in these donors also remained statistically equivalent to U.S. population norms. CONCLUSIONS This study represents the longest postdonation follow-up and offers unique insight related to HRQOL in a highly diverse patient population. Although LLDs continue to maintain excellent HRQOL outcomes up to 20 y after donation, continued lifetime follow-up is required to accurately provide young, healthy potential donors with an accurate description of the risks that they may incur on aging. BACKGROUND Can factors within the Electronic Residency Application Service application be used to predict the success of general surgery residents as measured by the Accreditation Council for Graduate Medical Education (ACGME) general surgery milestones? METHODS This is a retrospective study of 21 residents who completed training at a single general surgery residency program. Electronic Residency Application Service applications were reviewed for objective data, such as age, US Medical Licensing Examination scores, and authorship of academic publications as well as for letters of recommendation, which were scored using a standardized grading system. These factors were correlated to resident success as measured by ACGME general surgery milestone outcomes using univariate and multivariate analyses. This study was conducted at a single academic tertiary care and level 1 trauma facility. Residents who completed general surgery residency training from the years of 2012-2018 were included in the study. RESULTS There were few correlations between application factors and resident success determined by the ACGME milestones. CONCLUSIONS Application factors alone do not account for ongoing growth and development throughout residency. Unlike the results presented in the literature for other surgical subspecialties, predicting general surgery resident success based on application factors is not straightforward. BACKGROUND A narrow-profile powered vascular stapler (PVS) was developed to provide superior access and precise staple placement in thoracic procedures. The objective of this study was to determine if the PVS would yield an equivalent rate of hemostatic interventions compared with standard of care (SOC) staplers in video-assisted thoracoscopic surgery lobectomy. MATERIALS AND METHODS A randomized, controlled, multicenter study was conducted comparing PVS with SOC staplers in lobectomies performed for non-small cell lung cancer. The primary performance endpoint was the incidence of intraoperative hemostatic interventions, and the primary safety endpoint was the frequency of postoperative bleeding-related interventions. RESULTS A total of 98 subjects participated in the SOC group and 103 in the PVS group. Rates of intraoperative hemostatic interventions were 5.3% and 8.3% for the SOC and PVS groups, respectively. These rates were not statistically different (P = 0.137), although the upper bound of the 95% confidence interval for the difference in intervention rates between PVC and SOC exceeded a predefined 3% criterion for equivalence. Simple compressions were performed more frequently in the PVS subjects, which accounted for the higher intervention rate in this group. Postoperative interventions for bleeding were required in one SOC subject (1.0%) and one subject from the PVS group (0.9%). Procedure-related adverse events occurred in 21 (21.9%) SOC subjects and 23 (21.9%) PVS subjects, with no adverse events related to use of the study devices. CONCLUSIONS The PVS exhibited similar overall safety and effectiveness to SOC staplers in video-assisted thoracoscopic surgery lobectomy. Oculodentodigital dysplasia (ODDD) is a disease caused by mutations in the GJA1 gene that encodes the gap-junctional protein connexin43 (Cx43). ODDD affects multiple organs, but craniofacial anomalies are typical. However, details on the timing of phenotypic presentation of these abnormalities and their correspondence with potential cellular changes are incomplete. Here, we perform the first assessment of the development of the ODDD craniofacial phenotype in the Cx43I130T/+ mouse model and show that the phenotypic features commonly found in patients with the disorder arise in mice between E17.5 and birth and become more profound with age. Using mice heterozygous for the I130T mutation of Gja1, we provide a detailed analysis of the craniofacial phenotype in this ODDD model using shape analyses based on micro-CT images. Results show that in addition to differences in facial bone morphology, there are significant shape differences in the cranial base. Mutant mice display delayed ossification at E17.5 and birth, particularly in bones of the face and cranial vault but ossification is normal at three months. Our immunohistochemical analyses of the palatine bone indicate that osteoblast differentiation is delayed in Cx43I130T/+ mice compared to their wildtype littermates, which likely contributes to the phenotypic variations observed in the facial bones. Our histological and immunohistochemical analyses of the synchondroses of the cranial base show no differences in molecular indicators of chondrocyte differentiation in mutant mice, suggesting that the differences to cranial base morphology displayed by Cx43I130T/+ mice are not due to differences in chondrocyte proliferation or differentiation. selleck chemical Together, our findings suggest that Cx43I130T/+ mice represent a surrogate model to not only inform about the craniofacial anomalies found in ODDD patients but also to show that reduced Cx43 function leads to phenotypic changes that are largely due to osteoblast defects.
