BACKGROUND AND OBJECTIVES The ACS-NSQIP surgical risk calculator is an online tool that estimates the risk of postoperative complications. Sacrectomies for chordoma are associated with a high rate of complications. This study was to determine if the ACS-NSQIP calculator can predict postoperative complications following sacrectomy. METHODS Sixty-five (42 male, 23 female) patients who underwent sacrectomy were analyzed using the Current Procedural Terminology (CPT) codes 49215 (excision of presacral/sacral tumor), 63001 (laminectomy of sacral vertebrae), 63728 (laminectomy for biopsy/excision of sacral neoplasm) and 63307 (sacral vertebral corpectomy for intraspinal lesion). The predicted rates of complications were compared to the observed rates. RESULTS Complications were noted in 44 (68%) patients. Of the risk factors available to input to the ACS-NSQIP calculator, tobacco use (OR, 20.4; P  less then  .001) was predictive of complications. The predicted risk of complications based off the CPT codes were 49215 (16%); 63011 (6%); 63278 (11%) and 63307 (15%). Based on ROC curves, the use of the ACS-NSQIP score were poor predictors of complications (49215, AUC 0.65); (63011, AUC 0.66); (63307, AUC 0.67); (63278, AUC 0.64). CONCLUSION The ACS-NSQIP calculator was a poor predictor of complications and was marginally better than a coin flip in its ability to predict complications following sacrectomy for chordoma.

AIM This study aimed to demonstrate the clinicopathologic findings of these lesions and also the importance of histological evaluation for prevention of misdiagnosing a benign-appearing malignant lesion. METHODS A descriptive study was conducted of 2,438 cases who had a diagnosis of cyst confirmed with pathology. The data of patients over the 6-year period between 2011 and 2017, including gender, age, location, prevalence, complications, and microscopic evaluation, were gathered. RESULTS From a total of 2,438 records with a clinical diagnosis of mucocutaneous cyst, 2077 had the pathologic diagnosis of cysts. They consisted of 910 women (43.8%) and 1167 men (56.1%) with a mean age of 42. The most common mucocutaneous cysts were epidermal cyst 994 (47.8%) followed by trichilemmal cyst 495 (23.8%). In 479 (19.6%) records, the clinical diagnosis was not congruent with histopathological diagnosis including 45 malignant cases. Basal cell carcinoma in 22 (48.9%) was the most common one. CONCLUSIONS This study reports on clinical characteristics of cutaneous cysts and the need for a decent diagnostic investigation, like histopathology, for achieving a reliable diagnosis regarding the benign mimicking malignant lesions, especially high risk ones. © 2020 The International Society of Dermatology.AIM To explore cortical activation during bimanual tasks and functional correlates in unilateral cerebral palsy (CP). METHOD This cross-sectional study included eight participants with unilateral CP (six females, two males; mean age [SD] 20y 10mo [5y&nbsp;10mo], 13y 8mo-31y 6mo) in Manual Ability Classification System levels II to III and nine age-matched participants with typical development (seven females, two males; mean age [SD] 17y 8mo [5y 7mo], 9y 4mo-24y 2mo). They performed bimanual symmetric squeezing (BSS) and bimanual asymmetric squeezing (BAS) tasks at 1Hz, and a pouring task with dominant hand (DPour) and a pouring task with non-dominant hand (NDPour) at 0.67Hz, all while a custom array of functional near-infrared spectroscopy (fNIRS) optodes were placed over their sensorimotor area. Mixed-effects were used to contrast groups, tasks, and hemispheres (corrected p-values [q] reported). Analysis of variance and t-tests compared performance measures across groups and tasks. RESULTS Participants with unilatask difficulty. Increased brain activity may be associated with poorer selective manual control. Specific patterns of brain activity may be related to impaired bimanual function. Published 2020.

The PETCAM trial evaluated the effect of PET-CT (intervention) vs no PET-CT (control) on surgical management. PET-CT resulted in 8% change in surgical management, therefore, we aimed to compare long-term outcomes (disease-free [DFS], overall survival [OS]). METHODS Trial recruitment (2005-2010) had prospective follow-up until 2013. Events from 2013 to 2017 were collected retrospectively. Survival was described by the Kaplan-Meier method and compared with log-rank test. Oncologic risk factors were calculated using Cox proportional hazard models. RESULTS Among 404 patients randomized, there were no differences in DFS (hazard ratio [HR] = 1.13; 95% confidence interval [CI], 0.89 to 1.43) or OS (HR, 1.02; 95% CI, 0.78-1.32) between groups. For all patients randomized, median DFS (PET-CT vs no PET-CT) was 16 months (95% CI, 13-18) and 15 months (95% CI, 11-22), P = .33. For patients who underwent liver resection (n = 368), DFS (17 vs 16 months, P = .51) and OS (58 months vs 52 months, P = .90) were similar between groups, respectively. Risk factors for DFS and OS were age, tumor size, node-positive disease, extrahepatic metastases and disease-free duration. CONCLUSION Preoperative PET-CT changes surgical management in a small percentage of cases, without effect on recurrence rates or long-term survival. © 2020 Wiley Periodicals, Inc.OBJECTIVES Meriolins, a kind of chemical hybrid between meridianins and variolins, have lately been determined as kinase inhibitors and reportedly have antitumour activity. However, there is currently no in-depth study for the action mechanism. This study aimed to elucidate the potentially antitumour action mechanism of Meriolin1 on human neuroblastoma (SH-SY5Y) cells. METHODS Firstly, cell viability was detected by MTT assay. Secondly, cell cycle, cell apoptosis, cell autophagy, reactive oxygen species and mitochondrial membrane potential (ΔΨm) were measured by flow cytometry. Then, cell cycle-associated proteins, Bcl-2 family proteins, Akt/MAPK proteins and autophagy-associated proteins expressions were evaluated by Western blot. Bcl-2 and Bax mRNA expressions were also evaluated by qRT-PCR. Furthermore, cell adhesion assay and Hoechst 33258 fluorescent staining were carried out to detect the effect of Meriolin1 on cell adhesion and morphology. Finally, to gain further insight into mechanism of action of Meriolin1 to CDK protein, the molecular docking study was performed by using the CDOCKER module of DS software.
