Background: As one of the forms of media and art most consumed in the world, Oscar-nominated movies should have their drug use representation monitored because of possibly influencing but also reflecting society’s behavior. Objective: To investigate drug use representation in scenes from movies nominated for the Academy Awards (Oscar) from 2008-2011, through media content analysis. Methods: 437 scenes from Oscar-nominated movies (best film, best actor and best actress categories) showing drug consumption and/or its effects were assessed. Each drug represented and identified in a given scene (i.e., drug use incident) was counted as a unit for the present study (n = 515). Survey settings were used to control for over- or under-estimation of the prevalence of a variable in a given year or movie. Results: All the Oscar-nominated movies portrayed at least one scene of drug use. There was a massive predominance of alcohol and tobacco in movies, with a high use among men who also use drugs, habitually or occasionally, but related to stress/tension, predominantly at home. However, there was a significant progressive increase in the use of drugs other than alcohol and tobacco, multiple drugs, and by women. Conclusion: These findings echo epidemiological studies on substance use in western countries, an overall trend towards greater home drug use representation and gender convergence since 1970, which increased since 2000. Monitoring drug use representation in Oscar-nominated movies may represent an important public health tool.

Storage lesions (SLs) occur when the red blood cell quality is altered during the preservation of blood units. Pre-storage leukoreduction would limit the number of SLs. The aims of this study were to evaluate the effectiveness of a leukoreduction filter for human use and the effect of pre-storage leukoreduction on some ematobiochemical parameters in stored canine whole blood. Seven canine blood units were tested. Each one was divided into two units—one leukoreduced (LRWB) and one non-leukoreduced (nLRWB). On each unit, we determined the complete blood count (CBC), lactate-dehydrogenase (LDH), electrolytes (Na+, K+, Cl−), morphological index (MI) and hemolysis, on storage days 0, 7, 14, 21, 28, 35, and 42. Leukoreduction allowed a 98.30% recovery of the RBC count, retaining 99.69% and 94.91% of WBCs and PLTs, respectively. We detected a significant increase of LDH and MI with strongly higher values in nLRWB compared to LRWB. A progressive increase in electrolytes and LDH concentrations was observed as indices of stored hemolysis. LDH showed significantly lower values in LRWB units compared to nLRWB, suggesting its release from leukocytes. In the majority of units, hemolysis reached 1% on the 42nd day of storage. We assert the human leukoreduction filter effectiveness on canine whole blood, and we recommend using nLRWB before day 14, especially for critically ill patients. The difference of the basal hemolysis (day 0) percentages observed between subjects suggests that more studies should be performed to confirm a possible inter-individual donor biological variability of RBC membrane resistance, as happens in humans.

AbstractObjectivesIn 2018, the ACGME (Accreditation Council for Graduate Medical Education) made a change to the maximum permissible number of consecutive nights a resident trainee can be on “night float,” from six to seven nights. To our knowledge, although investigators have studied overall discrepancy rates and discrepancy rates as a function of shift length or perceived workload of a particular shift, no study has been performed to evaluate resident-faculty discrepancy rates as a quality/performance proxy, to see whether resident performance declines as a function of the number of consecutive nights. Our hypothesis is that we would observe a progressive increase in significant overnight resident – attending discrepancies over the 7 days’ time.MethodsA total of 8,488 reports were extracted between 4/26/2019 to 8/22/2019 retrospectively. Data was obtained from the voice dictation system report server. Exported query was saved as a .csv file format and analyzed using Python packages. A “discrepancy checker” was created to search all finalized reports for the departmental standard heading of “Final Attending Report,” used to specify any significant changes from the preliminary interpretation.ResultsModel estimates varied on different days however there were no trends or patterns to indicate a deterioration in resident performance throughout the week. There were comparable probabilities throughout the week, with 2.17% on Monday, 2.35% on Thursday and 2.05% on Friday.ConclusionsOur results reveal no convincing trend in terms of overnight report discrepancies between the preliminary report generated by the night float resident and the final report issued by a faculty the following morning. These results are in support of the ACGME’s recent change in the permissible number of consecutive nights on night float. We did not prove our hypothesis that resident performance on-call in the domain of report accuracy would diminish over seven consecutive nights while on the night float rotation. Our results found that performance remained fairly uniform over the course of the week.

Abstract Introduction Atrial fibrillation (AF) ablation and Atrioventricular Node (AVN) ablation are both important non-pharmacological therapy of AF. In spite of increased availability of AF ablation data, that of AVN ablation per se is limited. Method AF ablation was identified using ICD-9 procedure code with principle diagnosis of AF from United States National Inpatient Sample database 2005–2014. From procedure and diagnosis codes of pacemaker insertion followed by ablation, the cohort who underwent AVN ablation was identified. Patients hospitalization with any diagnosis of other type of arrythmia or epicardial ablation were excluded. Complications were defined as per the Agency for Health Care Research and Quality guideline. Results Total AF ablation was noted to increase from 2005- 2011, and declined steadily from 2011–2014. In contrast, the number of AVN ablations increased from 4505 cases to 5175 (Figure 1). AVN ablation were mainly performed in elderly patient (mean age 72), and increasingly in patient with higher Charlson Commobidity index (0.9 to 1.7)and higher CHA2DS2-VASc score (2.8 to 3.7) (Table 1). An increasing trend in procedure complications but no significant change in mortalitywere observed with AVN ablation. Progressive increase in the length of stay and the hospitalization cost were also observed over the years with AVN ablation. Conclusion AVN ablation is being performed at a steady volume, and increasingly in patients with multiple comorbidities. This trend although was not associated with increased mortality, it was associated with increased hospital complications. Funding Acknowledgement Type of funding source: None

Background: Sociodemographic data indicate the progressive increase in life expectancy and the prevalence of Alzheimer’s disease (AD). AD is raised as one of the greatest public health problems. Its etiology is twofold: on the one hand, non-modifiable factors and on the other, modifiable. Objective: This study aims to develop a processing framework based on machine learning (ML) and optimization algorithms to study sociodemographic, clinical, and analytical variables, selecting the best combination among them for an accurate discrimination between controls and subjects with major neurocognitive disorder (MNCD). Methods: This research is based on an observational-analytical design. Two research groups were established: MNCD group (n = 46) and control group (n = 38). ML and optimization algorithms were employed to automatically diagnose MNCD. Results: Twelve out of 37 variables were identified in the validation set as the most relevant for MNCD diagnosis. Sensitivity of 100%and specificity of 71%were achieved using a Random Forest classifier. Conclusion: ML is a potential tool for automatic prediction of MNCD which can be applied to relatively small preclinical and clinical data sets. These results can be interpreted to support the influence of the environment on the development of AD.

AbstractThe Cambrian Explosion by nature is a three-phased explosion of animal body plans alongside episodic biomineralization, pulsed change of generic diversity, body size variation, and progressive increase of ecosystem complexity. The Cambrian was a time of crown groups nested by numbers of stem groups with a high-rank taxonomy of Linnaean system (classes and above). Some stem groups temporarily succeeded while others were ephemeral and underrepresented by few taxa. The high number of stem groups in the early history of animals is a major reason for morphological gaps across phyla that we see today. Most phylum-level clades achieved their maximal disparity (or morphological breadth) during the time interval close to their first appearance in the fossil record during the early Cambrian, whereas others, principally arthropods and chordates, exhibit a progressive exploration of morphospace in subsequent Phanerozoic. The overall envelope of metazoan morphospace occupation was already broad in the early Cambrian though it did not reach maximal disparity nor has diminished significantly as a consequence of extinction since the Cambrian. Intrinsic and extrinsic causes were extensively discussed but they are merely prerequisites for the Cambrian Explosion. Without the molecular evolution, there could be no Cambrian Explosion. However, the developmental system is alone insufficient to explain Cambrian Explosion. Time-equivalent environmental changes were often considered as extrinsic causes, but the time coincidence is also insufficient to establish causality. Like any other evolutionary event, it is the ecology that make the Cambrian Explosion possible though ecological processes failed to cause a burst of new body plans in the subsequent evolutionary radiations. The Cambrian Explosion is a polythetic event in natural history and manifested in many aspects. No simple, single cause can explain the entire phenomenon.
