Improving Colon Cancer Screening Rates in an Ambulatory Resident Clinic

In the US, colorectal cancer (CRC) is the third leading cause of cancer-related deaths. According to the 2018 CDC Behavioral Risk Factor Surveillance System survey, 68.8% of US adults between 50 and 75 were up to date on colorectal screening (CRCS) across all screening modalities. In light of the COVID-19 pandemic, screening has dropped even further and is still 50% below pre-pandemic levels. At Jefferson, our CRCS rate is below the national average at 55.4%. Given the importance of regular screening for CRC prevention, this is clearly inadequate. There are several barriers to completing an invasive screening modality like a colonoscopy, but FIT testing may be a more feasible option. Our aim was to increase the colonoscopy screening rate at JHAP by 15% over a period of eight months (September-April)

Boundaries of Semantic Distraction: Dominance and Lexicality Act at Retrieval

Three experiments investigated memory for semantic information with the goal of determining boundary conditions for the manifestation of semantic auditory distraction. Irrelevant speech disrupted the free recall of semantic category-exemplars to an equal degree regardless of whether the speech coincided with presentation or test phases of the task (Experiment 1) and occurred regardless of whether it comprised random words or coherent sentences (Experiment 2). The effects of background speech were greater when the irrelevant speech was semantically related to the to-be-remembered material, but only when the irrelevant words were high in output dominance (Experiment 3). The implications of these findings in relation to the processing of task material and the processing of background speech is discussed

Avian W and mammalian Y chromosomes convergently retained dosage-sensitive regulators

After birds diverged from mammals, different ancestral autosomes evolved into sex chromosomes in each lineage. In birds, females are ZW and males are ZZ, but in mammals females are XX and males are XY. We sequenced the chicken W chromosome, compared its gene content with our reconstruction of the ancestral autosomes, and followed the evolutionary trajectory of ancestral W-linked genes across birds. Avian W chromosomes evolved in parallel with mammalian Y chromosomes, preserving ancestral genes through selection to maintain the dosage of broadly expressed regulators of key cellular processes. We propose that, like the human Y chromosome, the chicken W chromosome is essential for embryonic viability of the heterogametic sex. Unlike other sequenced sex chromosomes, the chicken W chromosome did not acquire and amplify genes specifically expressed in reproductive tissues. We speculate that the pressures that drive the acquisition of reproduction-related genes on sex chromosomes may be specific to the male germ line

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Acute Mitral Regurgitation Presenting with Right Upper Lobe Opacification

We describe a rare entity in which acute mitral regurgitation causes asymmetric findings on chest radiograph. The patient presented with rapid-onset respiratory failure from flash pulmonary edema. She had unilateral infiltrates on chest radiograph, which evoked infectious etiology. However, we identified a flail mitral valve leaflet, for which the patient received an emergent mitral valve replacement. Fortunately, she made a full recovery. We discuss the mechanism of the asymmetric chest radiograph findings, which we were able to confirm using a transesophageal echocardiogram

Effusive-Constrictive Pericarditis due to Poorly Differentiated Carcinoma of the Mediastinum

A 33-year-old male developed subacute effusiveconstrictive pericarditis with recurrent pleural effusions and mediastinal lymphadenopathy. He was found to have poorly differentiated carcinoma of the mediastinum that led to constrictive physiology not amenable to medical or surgical management, ultimately requiring hospice. This case was remarkable for its rare etiology and presentation
