Human and AI collaboration in the higher education environment: opportunities and concerns.

In service of the goal of examining how cognitive science can facilitate human-computer interactions in complex systems, we explore how cognitive psychology research might help educators better utilize artificial intelligence and AI supported tools as facilitatory to learning, rather than see these emerging technologies as a threat. We also aim to provide historical perspective, both on how automation and technology has generated unnecessary apprehension over time, and how generative AI technologies such as ChatGPT are a product of the discipline of cognitive science. We introduce a model for how higher education instruction can adapt to the age of AI by fully capitalizing on the role that metacognition knowledge and skills play in determining learning effectiveness. Finally, we urge educators to consider how AI can be seen as a critical collaborator to be utilized in our efforts to educate around the critical workforce skills of effective communication and collaboration.

Demystifying the 'hidden curriculum' for minoritized graduate students.

Graduate programs in the biomedical sciences dedicate considerable resources to recruiting students from underrepresented racial and ethnic groups. However, students from these minoritized groups have decreased access to the 'hidden curriculum' that must be navigated in order to be successful in graduate school. Here, we describe a student-led initiative at Johns Hopkins University, the Hidden Curriculum Symposium, that is organized to help prepare new students from underrepresented groups for graduate school. Preliminary evidence from surveys suggests that the initiative does increase the preparedness of minoritized students, and we believe this approach could also prove useful at other academic institutions.

Using simulation as a platform to prepare for ear, nose and throat emergencies in the coronavirus disease 2019 era and beyond.

BACKGROUND: Following limited clinical exposure during the coronavirus disease 2019 pandemic, a simulation-based platform aimed at providing a unique and safe learning tool was established. The aim was to improve the skills, knowledge and confidence of new ENT doctors. METHOD: The course was developed through 5 iterations over 28 months, moving from a half-day session to 2 full-day courses with more scenarios. Participant, faculty and local simulation team feedback drove course development. High-fidelity scenarios were provided, ranging from epistaxis to stridor, using technology including SimMan3 G mannequin, mask-Ed™ and nasendoscopy simulators. RESULTS: Participant feedback consistently demonstrated that the knowledge and skills acquired enhanced preparedness for working in ENT, with impact being sustained in clinical practice. CONCLUSION: Preparing healthcare professionals adequately is essential to enhancing patient safety. This simulation course has been effective in supporting new doctors in ENT and has subsequently been rolled out at a national level.

Challenges for research uptake for health policymaking and practice in low- and middle-income countries: a scoping review.

BACKGROUND: An estimated 85% of research resources are wasted worldwide, while there is growing demand for context-based evidence-informed health policymaking. In low- and middle-income countries (LMICs), research uptake for health policymaking and practice is even lower, while little is known about the barriers to the translation of health evidence to policy and local implementation. We aimed to compile the current evidence on barriers to uptake of research in health policy and practice in LMICs using scoping review. METHODS: The scoping review followed the Preferred Reporting Items for Systematic Review and Meta-Analyses-extension for Scoping Reviews (PRISMA-ScR) and the Arksey and O'Malley framework. Both published evidence and grey literature on research uptake were systematically searched from major databases (PubMed, Cochrane Library, CINAHL (EBSCO), Global Health (Ovid)) and direct Google Scholar. Literature exploring barriers to uptake of research evidence in health policy and practice in LMICs were included and their key findings were synthesized using thematic areas to address the review question. RESULTS: A total of 4291 publications were retrieved in the initial search, of which 142 were included meeting the eligibility criteria. Overall, research uptake for policymaking and practice in LMICs was very low. The challenges to research uptake were related to lack of understanding of the local contexts, low political priority, poor stakeholder engagement and partnership, resource and capacity constraints, low system response for accountability and lack of communication and dissemination platforms. CONCLUSION: Important barriers to research uptake, mainly limited contextual understanding and low participation of key stakeholders and ownership, have been identified. Understanding the local research and policy context and participatory evidence production and dissemination may promote research uptake for policy and practice. Institutions that bridge the chasm between knowledge formation, evidence synthesis and translation may play critical role in the translation process.

Burden of neglected tropical diseases and access to medicine and diagnostics in Ethiopia: a scoping review.

BACKGROUND: More than 1.7 billion people are affected by neglected tropical diseases (NTDs) worldwide. Forty percent of the NTD-affected people live in Africa with the poorest, most vulnerable, and hard to reach geographical areas. The NTDs cause significant social and economic burden and deepen marginalization and stigmatization. The World Health Organization's current roadmap for NTD aims to prevent, control, eliminate, or eradicate 20 tropical diseases. Ethiopia experiences a high burden of these diseases, but current access to diagnostics, medicine, and/or care has been little explored to inform the country's NTD strategic plan. The overall purpose of the scoping review was to map and characterize the burden of NTDs and challenges in access to diagnostics, medicine, and/or care in Ethiopia. METHODS: A systematic search of evidence was conducted in PubMed, Cochrane Library, and Google Scholar from January 2000 until May 2022, without restrictions of language or study design. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Review was followed for screening of studies. Key findings were extracted and narrated qualitatively. RESULTS: The search resulted in 4532 articles, of which 105 met the inclusion criteria and were included in the scoping review under three themes: burden of NTDs, access to diagnostics, medicine and/or care, and key barriers. Although gains have been made in the prevention and control of NTDs in Ethiopia, the burden remains high, and progress in access to diagnostics, medicine/drugs, and/or care is very slow. Poverty, poor quality of life, and underfunding of NTD programs decelerate the process of NTD elimination program in the country. CONCLUSIONS: The scoping review identified a considerable number of studies on the burden of NTDs in Ethiopia and strategies for diagnosis, treatment, and/or care; however, there is a paucity of evidence on the suitability and potential benefits of novel diagnostic technologies and medicines in the country. A regular review and analysis of such country-level evidence is important to inform the country NTDs roadmap and local implementation strategies.

Do funding sources complement or substitute? Examining the impact of cancer research publications.

Academic research often draws on multiple funding sources. This paper investigates whether complementarity or substitutability emerges when different types of funding are used. Scholars have examined this phenomenon at the university and scientist levels, but not at the publication level. This gap is significant since acknowledgement sections in scientific papers indicate publications are often supported by multiple funding sources. To address this gap, we examine the extent to which different funding types are jointly used in publications, and to what extent certain combinations of funding are associated with higher academic impact (citation count). We focus on three types of funding accessed by UK-based researchers: national, international, and industry. The analysis builds on data extracted from all UK cancer-related publications in 2011, thus providing a 10-year citation window. Findings indicate that, although there is complementarity between national and international funding in terms of their co-occurrence (where these are acknowledged in the same publication), when we evaluate funding complementarity in relation to academic impact (we employ the supermodularity framework), we found no evidence of such a relationship. Rather, our results suggest substitutability between national and international funding. We also observe substitutability between international and industry funding.

BitBrain and Sparse Binary Coincidence (SBC) memories: Fast, robust learning and inference for neuromorphic architectures.

We present an innovative working mechanism (the SBC memory) and surrounding infrastructure (BitBrain) based upon a novel synthesis of ideas from sparse coding, computational neuroscience and information theory that enables fast and adaptive learning and accurate, robust inference. The mechanism is designed to be implemented efficiently on current and future neuromorphic devices as well as on more conventional CPU and memory architectures. An example implementation on the SpiNNaker neuromorphic platform has been developed and initial results are presented. The SBC memory stores coincidences between features detected in class examples in a training set, and infers the class of a previously unseen test example by identifying the class with which it shares the highest number of feature coincidences. A number of SBC memories may be combined in a BitBrain to increase the diversity of the contributing feature coincidences. The resulting inference mechanism is shown to have excellent classification performance on benchmarks such as MNIST and EMNIST, achieving classification accuracy with single-pass learning approaching that of state-of-the-art deep networks with much larger tuneable parameter spaces and much higher training costs. It can also be made very robust to noise. BitBrain is designed to be very efficient in training and inference on both conventional and neuromorphic architectures. It provides a unique combination of single-pass, single-shot and continuous supervised learning; following a very simple unsupervised phase. Accurate classification inference that is very robust against imperfect inputs has been demonstrated. These contributions make it uniquely well-suited for edge and IoT applications.

Systematic review of the diagnosis and management of necrotising otitis externa: Highlighting the need for high-quality research.

OBJECTIVES: To present a systematic review and critical analysis of clinical studies for necrotising otitis externa (NOE), with the aim of informing best practice for diagnosis and management. DESIGN: Medline, Embase, Cochrane Library and Web of Science were searched from database inception until 30 April 2021 for all clinical articles on NOE. The review was registered on PROSPERO (ID: CRD42020128957) and conducted in accordance with PRISMA guidelines. RESULTS: Seventy articles, including 2274 patients were included in the final synthesis. Seventy-three percent were retrospective case series; the remainder were of low methodological quality. Case definitions varied widely. Median patient age was 69.2 years; 68% were male, 84% had diabetes and 10% had no reported immunosuppressive risk factor. Otalgia was almost universal (96%), with granulation (69%) and oedema (76%) the commonest signs reported. Pseudomonas aeruginosa was isolated in 62%, but a range of bacterial and fungal pathogens were reported and 14% grew no organism. Optimal imaging modality for diagnosis or follow-up was unclear. Median antimicrobial therapy duration was 7.2 weeks, with no definitive evidence for optimal regimens. Twenty-one percent had surgery with widely variable timing, indication, or procedure. One-year disease-specific mortality was 2%; treatment failure and relapse rates were 22% and 7%, respectively. CONCLUSION: There is a lack of robust, high-quality data to support best practice for diagnosis and management for this neglected condition. A minimum set of reporting requirements is proposed for future studies. A consensus case definition is urgently needed to facilitate high-quality research.

Idiopathic Myointimal Hyperplasia of the Mesenteric Veins: A Rare Imitator of Inflammatory Bowel Disease.

Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a rare cause of chronic colonic ischemia characterized by intimal smooth muscle proliferation and luminal narrowing of the small to medium sized mesenteric veins. It predominantly affects the rectosigmoid colon in otherwise healthy, middle-aged males. Definitive diagnosis and treatment are surgical; however, patients are frequently misdiagnosed, which often results in a protracted clinical course. We describe a case of IMHMV presenting as left hemicolitis in a 53-year-old male, as well as the endoscopic, histopathologic, and radiographic findings that established the diagnosis.

Collection and Utilization of Patient-Reported Outcome Measures in a Colorectal Surgery Clinic.

INTRODUCTION: The routine collection of patient-reported outcome measures (PROMs) promises to improve patient care. However, in colorectal surgery, PROMs are uncommonly collected outside of clinical research studies and rarely used in clinical care. We designed and implemented a quality improvement project with the goals of routinely collecting PROMs and increasing the frequency that PROMs are utilized by colorectal surgeons in clinical practice. METHODS: This mixed-methods, quality improvement project was conducted in the colorectal surgery clinic of a tertiary academic medical center. Patients were administered up to five PROMs before each appointment. PROM completion rates were measured. Additionally, we performed two educational interventions to increase utilization of our electronic health record's PROM dashboard by colorectal surgeons. Utilization rates and attitudes toward the PROM dashboard were measured. RESULTS: Overall, patients completed 3600 of 3977 (90.9%) administered PROMs during the study period. At baseline, colorectal surgeons reviewed 6.7% of completed PROMs. After two educational interventions, this increased to 39.3% (P = 0.004). Colorectal surgeons also felt that the PROM dashboard was easier to use. Barriers to greater PROM dashboard utilization included poor user interface/user experience and a perceived lack of knowledge, time, and relevance. CONCLUSIONS: The collection of PROMs in colorectal surgery clinics is feasible and can result in high PROM completion rates. Educational interventions can improve the utilization of PROMs by colorectal surgeons in clinical practice. Our experience collecting PROMs through this quality improvement initiative can serve as a template for other colorectal surgery clinics interested in collecting and utilizing data from PROMs.

Analysis of the interactions between small pulmonary nodules, clinical factors and the risk of malignancy in the chest following diagnosis of head and neck cancer.

BACKGROUND: This study aims to investigate radiological and clinical factors which predict malignancy in indeterminate pulmonary nodules in patients with head and neck cancer (HNC). METHODS: Prospective data were collected in 424 patients who were reviewed in the NHS Lothian HNC multidisciplinary meeting from May 2016 to May 2018. Staging and follow-up CT chest imaging were reviewed to identify and assess pulmonary nodules in all patients. RESULTS: About 61.8% of patients had at least one pulmonary nodule at staging CT. In total, 25 patients developed malignancy in the chest. Metastatic disease in the chest was significantly associated with unknown or negative p16 status (p < .0005). Pleural indentation and spiculation were associated with indeterminate nodules, subsequently being shown to represent metastatic disease (p > .0005 and p = .046, respectively). CONCLUSION: Negative or unknown p16 status was associated with an increased propensity to develop metastatic disease in the chest in patients with HNC.

Pharmacological activation of the Sonic hedgehog pathway with a Smoothened small molecule agonist ameliorates the severity of alcohol-induced morphological and behavioral birth defects in a zebrafish model of fetal alcohol spectrum disorder.

Ethanol exposure during the early stages of embryonic development can lead to a range of morphological and behavioral differences termed fetal alcohol spectrum disorders (FASDs). In a zebrafish model, we have shown that acute ethanol exposure at 8-10 hr postfertilization (hpf), a critical time of development, produces birth defects similar to those clinically characterized in FASD. Dysregulation of the Sonic hedgehog (Shh) pathway has been implicated as a molecular basis for many of the birth defects caused by prenatal alcohol exposure. We observed in zebrafish embryos that shh expression was significantly decreased by ethanol exposure at 8-10 hpf, while smo expression was much less affected. Treatment of zebrafish embryos with SAG or purmorphamine, small molecule Smoothened agonists that activate Shh signaling, ameliorated the severity of ethanol-induced developmental malformations including altered eye size and midline brain development. Furthermore, this rescue effect of Smo activation was dose dependent and occurred primarily when treatment was given after ethanol exposure. Markers of Shh signaling (gli1/2) and eye development (pax6a) were restored in embryos treated with SAG post-ethanol exposure. Since embryonic ethanol exposure has been shown to produce later-life neurobehavioral impairments, juvenile zebrafish were examined in the novel tank diving test. Our results further demonstrated that in zebrafish embryos exposed to ethanol, SAG treatment was able to mitigate long-term neurodevelopmental impairments related to anxiety and risk-taking behavior. Our results indicate that pharmacological activation of the Shh pathway at specific developmental timing markedly diminishes the severity of alcohol-induced birth defects.

What's the magic number? Impact of time to initiation of treatment for rectal cancer.

BACKGROUND: National guidelines, including the National Accreditation Program for Rectal Cancer, recommend initiation of rectal cancer treatment within 60 days of diagnosis; however, the effect of timely treatment initiation on oncologic outcomes is unclear. The purpose of this study was to evaluate the impact on oncologic outcomes of initiation of rectal cancer treatment within 60 days of diagnosis. METHODS: This was a retrospective review of stage II/III rectal cancer patients performed using the United States Rectal Cancer Consortium, a collaboration of 6 academic medical centers. Patients with clinical stage II/III rectal cancer who underwent radical resection between January 1, 2010 and December 31, 2018 were included. The primary exposure was treatment initiation, defined as either resection or initiation of chemotherapy or chemoradiotherapy, within 60 days of diagnosis. The primary outcome was disease recurrence, and the secondary outcome was all-cause mortality. RESULTS: A total of 1,031 patients meeting inclusion criteria were included in the analysis. Treatment was initiated within 60 days of diagnosis in 830 patients (80.5%) and after 60 days in 201 patients (20.3%). In multivariable logistic regression, older age, non-White race, and residence greater than 100 miles from the treatment center were significantly associated with delay in treatment beyond 60 days. In survival analysis, 167 patients (16.2%) experienced recurrent disease, and 127 patients (12.3%) died of any cause. In an adjusted model accounting for pathologic staging, treatment sequence, distance to care, age, comorbidities, treatment center, and receipt of adjuvant chemotherapy, neither progression-free survival nor all-cause mortality was significantly associated with timely initiation of therapy with hazard ratios of 1.09 (0.70, 1.69) and 1.03 (0.63, 1.66), respectively. CONCLUSION: This study found no difference in oncologic outcomes with initiation of treatment beyond 60 days.

Innovation policy instruments (non-price) for medical innovation

Innovation policy instruments are policy interventions with a specific mechanism of action that influences the innovation process. This Oslo Medicines Initiative technical report presents a broad range of such instruments available to national policy-makers in support of innovation for new medicines (excluding those focused on price, which are covered elsewhere in the report series). This report explores various types of policy instrument, based on reviews of the literature on policies for innovation in the medical and other sectors. For each type identified, the report explores the mechanisms of action, the effects these have and where they occur, and the extent to which these instruments have been implemented globally. It also sets out considerations for their effective implementation. The report demonstrates that the long-established push/pull (supply/demand) framing that dominates discourse around medical innovation can be broadened, providing policy-makers with instruments to supplement push/pull approaches, by emphasizing the role of communication, collaboration and coordination in supporting the emergence of medicines to address societal needs.

A de-escalated treatment strategy in the management of paediatric cervicofacial actinomycosis.

Actinomycosis is a rare invasive bacterial disease that is characterised by granulomatous inflammation often mistaken as malignancy. Traditionally, this has been managed with prolonged courses of antibiotics with durations up to 6-12 months. Surgical intervention as an adjuvant treatment has been shown to reduce the length of antibiotic treatment significantly to 4 weeks. We report a case of cervicofacial actinomycosis in a 12-year-old girl who was adequately treated with an 11-day course of antibiotics without surgical intervention and shows no signs of recurrence at 6 months post-treatment.

Spaceflight validation of technology for point-of-care monitoring of peripheral blood WBC and differential in astronauts during space missions.

During long duration orbital space missions, astronauts experience immune system dysregulation, the persistent reactivation of latent herpesviruses, and some degree of clinical incidence. During planned NASA 'Artemis' deep space missions the stressors that cause this phenomenon will increase, while clinical care capability will likely be reduced. There is currently minimal clinical laboratory capability aboard the International Space Station (ISS). The ability to monitor the white blood cell count (WBC) and differential during spaceflight has been an unmet NASA medical requirement, primarily due to a lack of capable hardware. We performed ground and flight validation of a device designed to monitor WBC and differential within minutes from a fingerstick blood sample. This device is miniaturized, robust, and generally compatible with microgravity operations. Ground testing for spaceflight consisted of vibration tolerance, power/battery and interface requirements, electromagnetic interference (EMI), and basic evaluation of sample preparation and operations in the context of spaceflight constraints. The in-flight validation performed aboard the ISS by two astronauts included assessment of three levels of control solution (blood) samples as well as a real time analysis of a fingerstick blood sample by one of the crewmembers. Flight and ground testing of the same lot of control solutions yielded similar total WBC values. There was some select discrepancy between flight and ground data for the differential analysis. However, the data suggest that this issue is due to compromise of the control solutions as a result of storage length before flight operations, and not due to a microgravity-associated issue with instrument performance. This evaluation also yielded lessons learned regarding crewmember training for technique-sensitive small-volume biosample collection and handling in microgravity. The fingerstick analysis was successful and was the first real-time hematology assessment performed during spaceflight. This device may provide an in-mission monitoring capability for astronauts thereby assisting Flight Surgeons and the crew medical officer during both orbital and deep space missions.
