    Multivariable logistic regression was used to test whether obesity is independently associated with the outcomes of interest after adjustment for other covariates. Results A total of 36,396 patients were included. There were 13,754 patients in the WOC group and 22,642 in the WC group. Among patients in the WOC group, the adjusted odds of mortality were 2.2 times higher for patients with a BMI ≥35 versus a BMI less then 35. Among the patients in the WC group, a BMI ≥35 was not a statistically significant predictor of mortality after adjustment for other covariates. Obese patients had increased odds of each outcome among the WOC group. Conclusions Our hypothesis was refuted by these data. In fact, the adverse effect of obesity was more evident among healthy patients.Background Recurrent laryngeal nerve (RLN) injury is a well-known, potentially serious complication of thyroid surgery. We investigated factors associated with RLN injury during thyroid surgery using a multi-institutional data set. Materials and methods Patients who underwent either lobectomy or total thyroidectomy were abstracted from the American College of Surgeons National Surgical Quality Improvement Program thyroidectomy-specific database (2016-2017). Baseline and operative factors associated with RLN injury ≤30 d of surgery were analyzed using bivariate and multivariate methods. Secondary complications of interest included unplanned reintubation and hypocalcemia. Results RLN injury occurred in 6.0% (n = 677) of the 11,370 patients included in the study. The RLN injury rate varied significantly based on the primary indication for surgery, from 4.3% in patients undergoing surgery for a single nodule to 9.0% in patients undergoing surgery for differentiated cancer (P less then 0.01). RLN injury occurred more often in thyroidectomies than lobectomies (6.9% versus 4.3%, P less then 0.01) and in surgeries without intraoperative nerve monitoring (6.5% versus 5.6%, P = 0.01). After multivariate adjustment, RLN injury was independently associated with age ≥65 y , total thyroidectomy (OR = 1.4, 95% CI 1.1-1.6), and diagnosis of thyroid malignancy (OR = 2.1, 95% CI = 1.6-2.7) (all P less then 0.001) but not intraoperative RLN monitoring (OR = 0.9, 95% CI = 0.7-1.0, P = 0.06). Conclusions In this large multi-institutional study, RLN injury ≤30 d of surgery occurred in nearly 6% of thyroid surgeries. This comprehensive analysis of RLN injury can be used to guide informed consent discussions and aid surgeons in identifying candidates who may be at higher risk for injury.Background Parathyroidectomy (PTX) has been demonstrated as an effective treatment for patients with secondary hyperparathyroidism (SHPT) of renal origin. However, severe hypocalcemia, called hungry bone syndrome (HBS), is a common complication following PTX in these patients and can lead to poor clinical outcomes, even death. Therefore, exploring risk factors for HBS and establishing a prediction nomogram allow intensive monitoring and prompt treating this postoperative complication, which is the main purpose of this study. Methods From October 2016 to October 2018, PTX with autotransplantation (PTX + AT) procedures were performed in 131 patients with SHPT of renal origin by a surgeon and his team in the Thyroid and Parathyroid Surgery Center, West China Hospital, Sichuan University, China. After applying the inclusion and exclusion criteria, a total of 114 patients were enrolled for analyses in this study. Comprehensive data including preoperative, intraoperative, and postoperative variables were prospectivotstrapping demonstrated preoperative iPTH, bone-ALP, preoperative corrected serum calcium, and total weight of resected parathyroid glands were independently associated with postoperative HBS. The nomogram including the abovementioned four independent predictors was constructed and showed better prediction performance than the other four predictors in terms of postoperative HBS. Conclusions On the basis of this study, we found higher preoperative iPTH level, higher bone-ALP level, heavier total weight of resected parathyroid glands, and lower preoperative corrected serum calcium level were independent predictors of postoperative HBS in patients with SHPT of renal origin. The nomogram can expediently, accurately, and objectively predict the risk of postoperative HBS in individual patient with SHPT of renal origin.Background Up to 30% of patients with sickle cell disease (SCD) develop chronic liver disease via etiologies including sickle cell hepatopathy, acquired viral hepatitis, or secondary hemochromatosis. It is unclear how many patients with SCD ultimately undergo liver transplantation (LT) and what factors are associated with survival after LT. In this study, we examined LT outcomes in these patients by reviewing the Scientific Registry of Transplant Recipients (SRTR) and our institutional experience. Methods Analysis of the SRTR identified 23 LT recipients and five simultaneous liver and kidney transplantation (SLKT) recipients with SCD. Patient demographics and graft and patient survival were analyzed. Two patients with SCD at our institution underwent SLKT. Chidamide Results Review of the SRTR revealed that recipients with SCD had significantly higher model for end-stage liver disease scores (33 versus 21, P = 0.004), preoperative intensive care unit admission (43.5% versus 19.1%, P = 0.007), preoperative dialysis (17.4% versus 4.9%, P = 0.009), and were more likely to be status 1 (26.1% versus 12.1%, P = 0.041) when compared with the reference population of African American LT recipients. Despite being higher risk at the time of LT, patients with SCD had equivalent posttransplant graft and patient survival when compared with the reference population (P = 0.5 and P = 0.2, respectively) and a 21 propensity score-matched group (P = 0.5 and P = 0.2, respectively). Two recent SLKT recipients with SCD from our institution have performed well with stable allograft function. Conclusions Data from the SRTR demonstrate that patients with SCD can expect equivalent graft and patient survival after LT despite exhibiting more comorbidities at the time of LT. The low number of patients with SCD who underwent LT in the SRTR in comparison with the rate of chronic liver disease in this population raises the question as to whether a disparity in access to LT exists for this complex population.
