The aim of this study was to evaluate the association between frailty and 30-day morbidity and mortality in patients with intertrochanteric femur fractures. Furthermore, the authors sought to identify a specific frailty index score that would help identify high-risk patients. This retrospective study evaluated 229 consecutive patients 50 years or older who presented to a single level I trauma center for surgical fixation of an intertrochanteric femur fracture. Frailty was determined using a previously validated 11-point modified frailty index (mFI) scale. Primary outcome variables included 30-day morbidity and mortality. Of the 229 patients included in this study, 82 (36%) had a postoperative complication and there were 10 (4%) mortalities. The most common complications were delirium (n=40; 17%) and acute kidney injury (n=25; 11%). Mean mFI score for those who developed a postoperative complication was 0.24 compared with 0.14 for those who did not ( P P =.006). This study demonstrates that the mFI is associated with 30-day morbidity and mortality in patients aged 50 years or older with intertrochanteric femur fractures. The authors identified an mFI score of 0.27 or more as the most robust predictor of increased 30-day morbidity and mortality following surgical fixation of intertrochanteric femur fractures.

Background Total shoulder arthroplasty has been demonstrated to be an effective treatment for arthritis of the glenohumeral joint. Prior studies have identified longer operative times as a risk factor for complications after numerous types of procedures. We hypothesized that increased operative time, in 20-min intervals, would be associated with complications following total shoulder arthroplasty. Methods Patients undergoing total shoulder arthroplasty from 2006 to 2015 were identified from the ACS-NSQIP database. Patient demographic information, perioperative parameters, and 30-day outcomes were retrieved. Pearson's Chi-square test and multivariate Poisson regression with robust error variance were used to analyze the relationship of operative time and outcomes. Results A total of 10,082 patients were included. Multivariate analysis revealed that for each increase in 20 min of operative time, there were significantly increased rates of any complication (relative risk (RR) 1.24, 95% confidence interval (CI) 1.19–1.26), anemia requiring transfusion (RR 1.33, 95%CI 1.26–1.4), peripheral nerve injury (RR 1.88, 95%CI 1.53–2.31), and urinary tract infection (RR 1.24, 95%CI 1.09–1.41). Discussion This study indicates that increasing operative time confers increased risk for postoperative complications following total shoulder arthroplasty. We anticipate the results of this manuscript will be used for provider education, policy decision-making, and potentially to derive algorithms that can improve safety and efficiency in total shoulder arthroplasty.

The aim of this study was to compare hospital outcomes for patients in a motorcycle collision with and without helmet use. The study was conducted as a retrospective analysis of the National Trauma Data Bank's 2013 data set, which included reported data from 100 hospitals across the United States.Inclusion criterion for this study is a motorcycle crash involving a driver or passenger. The total number of patients in motorcycle crashes as reported by the National Trauma Data Bank in 2013 was 10,345. Helmet use, hospital stay, ICU and ventilation days, mortality, Glasgow Coma Score, Injury Severity Score, patient payer mix, and complication data were obtained.Patients were divided into two groups: those wearing a helmet (n = 6250) and those without (n = 4095). Patients not wearing a helmet had an increased risk of admission to the ICU (OR = 1.36, P 0.001, CI 1.25-1.48), requiring ventilation support (OR = 1.55, P 0.001, CI 1.39-1.72), presenting with a Glasgow Coma Score of eight or below (OR = 2.15, P 0.001), and in-patient mortality (OR = 2.00, P 0.001, CI 1.58-2.54). Unhelmeted patients were more likely to have government insurance or be uninsured than those patients wearing a helmet (P 0.001).It is not well understood why many states are repealing or have repealed universal helmet laws. Lack of helmet use increases the severity of injury in traumatized patients leading to a substantial financial impact on health care costs. Our analysis suggests the need to revisit the issue regarding laws that require protective headwear while riding motorcycles because of the individual and societal impact.III.

Background: The primary aim of this study was to investigate whether USMLE board scores correlate with the emotional intelligence of medical students. We hypothesized that higher Step 1 scores would be associated with lower emotional intelligence.Methods: This prospective study included medical students who self-reported their USMLE Step 1 score and completed a survey designed to measure their emotional intelligence. The survey was composed of a Grit Scale, a Hardiness-Resilience quiz, and the “Reading the Mind in the Eyes” quiz. For participants who completed all three instruments, a composite score was equal to the sum of the three scoresThis study was performed at Emory University School of Medicine in Atlanta, Georgia. Of the 85 medical students who were recruited to participate, 72 completed all aspects of this study (85% completion rate).Results: Pearson correlation analyses showed that grit (r=-0.105, P=0.34), hardiness-resilience (r=-0.230, P=0.04), the eye quiz (r=-0.033, P=0.79), and the composite score (r=-0.187, P=0.12) wereinversely correlated with USMLE scores. Participants who scored higher than the national average had a lower mean hardiness score compared to those who scored lower than the national average (P=0.03). Those who scored at least one standard deviation above the national average had a lowermean hardiness score (P=0.05) and a lower composite score (P=0.04).Conclusion: Higher USMLE Step 1 scores are associated with lower emotional intelligence, namely hardiness, in medical students.Keywords: EMOTIONAL INTELLIGENCE, USMLE STEP 1, HARDINESS, GRIT, RESIDENCY SELECTION

The DNA damage response (DDR) promotes genome integrity and serves as a cancer barrier in precancerous lesions but paradoxically may promote cancer survival. Genes that activate the DDR when dysregulated could function as useful biomarkers for outcome in cancer patients. Using a siRNA screen in human pancreatic cancer cells, we identified the CHD5 tumor suppressor as a gene, which, when silenced, activates the DDR. We evaluated the relationship of CHD5 expression with DDR activation in human pancreatic cancer cells and the association of CHD5 expression in 80 patients with resected pancreatic adenocarcinoma (PAC) by immunohistochemical analysis with clinical outcome. CHD5 depletion and low CHD5 expression in human pancreatic cancer cells lead to increased H2AX-Ser139 and CHK2-Thr68 phosphorylation and accumulation into nuclear foci. On Kaplan-Meier log-rank survival analysis, patients with low CHD5 expression had a median recurrence-free survival (RFS) of 5.3 vs 15.4 months for patients with high CHD5 expression (P=0.03). In 59 patients receiving adjuvant chemotherapy, low CHD5 expression was associated with decreased RFS (4.5 vs 16.3 months; P=0.001) and overall survival (OS) (7.2 vs 21.6 months; P=0.003). On multivariate Cox regression analysis, low CHD5 expression remained associated with worse OS (HR: 3.187 (95% CI: 1.49-6.81); P=0.003) in patients undergoing adjuvant chemotherapy. Thus, low CHD5 expression activates the DDR and predicts for worse OS in patients with resected PAC receiving adjuvant chemotherapy. Our findings support a model in which dysregulated expression of tumor suppressor genes that induce DDR activation can be utilized as biomarkers for poor outcome.

Background. Repeated, self-damaging behaviour occurring in the context of borderline personality disorder (BPD) may reflect impairments in decision-making and planning cognition. However, there has been no systematic neuropsychological examination of these particular cognitive functions in patients diagnosed with BPD. Such investigations may improve our understanding of the possible role of brain dysfunction in BPD and improve the characterization of the psychological difficulties associated with this disorder.Method. Forty-two psychiatric patients with a diagnosis of DSM-III-R BPD (41 of whom gave a history of self-harm), without a history of specified ‘psychoses’ or current major affective disorder, were clinically assessed before completing computerized tasks of decision-making and planning previously shown to be sensitive to frontal lobe dysfunction, and tests of spatial and pattern visual recognition memory previously shown to be sensitive to frontal lobe damage and temporal lobe damage respectively. The performance of the BPD patient group was compared with that of a non-clinical control group consisting of 42 subjects.Results. The performance of the BPD patients on the decision-making task was characterized by a pattern of delayed and maladaptive choices when choosing between competing actions, and by impulsive, disinhibited responding when gambling on the outcome of their decisions. BPD patients also showed impairments on the planning task. There was no evidence of impaired visual recognition memory. Additional analyses suggested only limited effects of current medication and history of previous substance use disorder.Conclusions. These findings suggest that BPD is associated with complex impairments in dissociable cognitive processes mediated by circuitry encompassing the frontal lobes. These impairments may mediate some of the behavioural changes evident in BPD. Further work is needed to examine the specificity of these findings.

High-grade versions of appendiceal goblet cell carcinoids (‘adenocarcinoma ex-goblet cell carcinoids’) are poorly characterized. We herein document 77 examples. Tumors occurred predominantly in females (74%), mean age 55 years (29–84), most with disseminated abdominal (77% peritoneal, 58% gynecologic tract involvement) and stage IV (65%) disease. Many presented to gynecologic oncologists, and nine had a working diagnosis of ovarian carcinoma. Metastases to liver (n =3) and lung (n =1) were uncommon and none arose in adenomatous lesions. Tumors had various histologic patterns, in variable combinations, most of which were fairly specific, making them recognizable as appendiceal in origin, even at metastatic sites: I: Ordinary goblet cell carcinoid/crypt pattern (rounded, non-luminal acini with well-oriented goblet cells), in variable amounts in all cases. II: Poorly cohesive goblet cell pattern (diffusely infiltrative cords/single files of signet ring-like/goblet cells). III: Poorly cohesive non-mucinous cell (diffuse-infiltrative growth of non-mucinous cells). IV: Microglandular (rosette-like glandular) pattern without goblet cells. V: Mixed ‘other’ carcinoma foci (including ordinary intestinal/mucinous). VI: goblet cell carcinoid pattern with high-grade morphology (marked nuclear atypia). VII: Solid sheet-like pattern punctuated by goblet cells/microglandular units. Ordinary nested/trabecular (‘carcinoid pattern’) was very uncommon. In total, 33(52%) died of disease, with median overall survival 38 months and 5-year survival 32%. On multivariate analysis perineural invasion and younger age (

This study investigated features of impulsivity in patients with borderline personality disorder (BPD) using the self-report Attention-Deficit Scales for Adults (ADSA) and computer-administered neurocognitive tasks. Forty-one patients with DSM-III-R BPD and 35 nonclinical control subjects were assessed by the ADSA, the National Adult Reading Test, and two computerized tasks mediated by the frontal lobes. Mean scores for seven ADSA scales (six of which relate to aspects of impulsivity) were significantly higher in the patient group compared with the control group. Also, the ADSA ratings for impaired coordination were increased in the BPD patients. The findings indicate that a range of aspects of impulsivity, as well as impaired coordination, are associated with patients selected on the basis of BPD. Also, in the patient group, but not in the control group, associations of the neurocognitive tasks indicated that, first, performance on a planning task related to dorsolateral frontal lobe functioning is correlated with aspects of impulsivity reflected by ADSA scale III ratings (involving disorganisation and lack of perseverance) and, second, performance on a decision-making task related to orbitofrontal functioning is correlated with ratings of impaired coordination. Further work is needed to establish the specificity of the findings.
