Putting Students in the Front and Center: Exploring and Refining Student Centered Learning Techniques

Student-centered learning (SCL) represents a growing trend in higher education that emphasizes active learning strategies in lieu of more traditional passive strategies such as lecture. This study explores different techniques under the rubric of SCL to evaluate the utility of selected tools to enhance student knowledge and student learning. Specifically, this study tests the use of student portfolios, flipped classrooms, digital learning strategies, and problem-based learning to enhance a student’s learning experience. Originating as a collaborative effort from a university faculty learning community, this study includes a multi-disciplinary look at the effects of SCL approaches in the fields of aviation, security, and intelligence

Use of multicriteria decision analysis for assessing the benefit and risk of over-the-counter analgesics

Objectives To test the ability of a multicriteria decision analysis (MCDA) model to incorporate disparate data sources of varying quality along with clinical judgement in a benefit–risk assessment of six well-known pain-relief drugs. Methods Six over-the-counter (OTC) analgesics were evaluated against three favourable effects and eight unfavourable effects by seven experts who specialise in the relief of pain, two in a 2-day facilitated workshop whose input data and judgements were later peer-reviewed by five additional experts. Key findings Ibuprofen salts and solubilised emerged with the best benefit–risk profile, followed by naproxen, ibuprofen acid, diclofenac, paracetamol and aspirin. Conclusions Multicriteria decision analysis enabled participants to evaluate the OTC analgesics against a range of favourable and unfavourable effects in a group setting that enabled all issues to be openly aired and debated. The model was easily communicated and understood by the peer reviewers, so the model should be comprehensible to physicians, pharmacists and other health professionals

Physiological-based cord clamping versus immediate cord clamping for infants born with a congenital diaphragmatic hernia (PinC):study protocol for a multicentre, randomised controlled trial

Introduction Pulmonary hypertension is a majordeterminant of postnatal survival in infants with acongenital diaphragmatic hernia (CDH). The current careduring the perinatal stabilisation period in these infantsmight contribute to the development of pulmonaryhypertension after birth—in particular umbilical cordclamping before lung aeration. An ovine model ofdiaphragmatic hernia demonstrated that cord clampingafter lung aeration, called physiological-based cordclamping (PBCC), avoided the initial high pressures in thelung vasculature while maintaining adequate blood flow,thereby avoiding vascular remodelling and aggravationof pulmonary hypertension. We aim to investigate if theimplementation of PBCC in the perinatal stabilisation periodof infants born with a CDH could reduce the incidence ofpulmonary hypertension in the first 24 hours after birth.Methods and analysis We will perform a multicentre,randomised controlled trial in infants with an isolatedleft-sided CDH, born at ≥35.0 weeks. Before birth, infantswill be randomised to either PBCC or immediate cordclamping, stratified by treatment centre and severity ofpulmonary hypoplasia on antenatal ultrasound. PBCCwill be performed using a purpose- built resuscitationtrolley. Cord clamping will be performed when the infantis considered respiratory stable, defined as a heartrate >100 bpm, preductal oxygen saturation >85%,while using a fraction of inspired oxygen of <0.5. Theprimary outcome is pulmonary hypertension diagnosedin the first 24 hours after birth, based on clinical andechocardiographic parameters. Secondary outcomesinclude neonatal as well as maternal outcomes.Ethics and dissemination Central ethical approvalwas obtained from the Medical Ethical Committee ofthe Erasmus MC, Rotterdam, The Netherlands (METC2019-0414). Local ethical approval will be obtained bysubmitting the protocol to the regulatory bodies and localinstitutional review boards

Rethinking the patient: using Burden of Treatment Theory to understand the changing dynamics of illness

<b>Background</b> In this article we outline Burden of Treatment Theory, a new model of the relationship between sick people, their social networks, and healthcare services. Health services face the challenge of growing populations with long-term and life-limiting conditions, they have responded to this by delegating to sick people and their networks routine work aimed at managing symptoms, and at retarding - and sometimes preventing - disease progression. This is the new proactive work of patient-hood for which patients are increasingly accountable: founded on ideas about self-care, self-empowerment, and self-actualization, and on new technologies and treatment modalities which can be shifted from the clinic into the community. These place new demands on sick people, which they may experience as burdens of treatment.<p></p> <b>Discussion</b> As the burdens accumulate some patients are overwhelmed, and the consequences are likely to be poor healthcare outcomes for individual patients, increasing strain on caregivers, and rising demand and costs of healthcare services. In the face of these challenges we need to better understand the resources that patients draw upon as they respond to the demands of both burdens of illness and burdens of treatment, and the ways that resources interact with healthcare utilization.<p></p> <b>Summary</b> Burden of Treatment Theory is oriented to understanding how capacity for action interacts with the work that stems from healthcare. Burden of Treatment Theory is a structural model that focuses on the work that patients and their networks do. It thus helps us understand variations in healthcare utilization and adherence in different healthcare settings and clinical contexts

The Lost Library of Anne Conway

The philosopher Anne Conway (1631-1679) owned a large library, and her reading and book ownership shaped her intellectual life in distinctive ways. Until now, however, almost nothing has been known about the details of her reading or her book collection. Current scholarship assumes that her library, like that of her husband, the third Viscount Conway (c. 1623–1683), was lost or dispersed after her death. This article presents previously unrecognised evidence of Conway’s book ownership, and identifies, for the first time, the only books currently known to survive from her personal library. It traces their path to their current location in the Old Library of Jesus College, Cambridge, through the library of the soldier, book collector, and Cambridge Fellow Francis Sterling (c. 1652-1692). The article demonstrates that the newly identified books reveal previously unknown patterns of intellectual exchange amongst Conway’s family, and argues that they have significant implications for our understanding of her early intellectual development

Ribonuclease inhibitor 1 regulates erythropoiesis by controlling GATA1 translation.

Ribosomal proteins (RP) regulate specific gene expression by selectively translating subsets of mRNAs. Indeed, in Diamond-Blackfan anemia and 5q- syndrome, mutations in RP genes lead to a specific defect in erythroid gene translation and cause anemia. Little is known about the molecular mechanisms of selective mRNA translation and involvement of ribosomal-associated factors in this process. Ribonuclease inhibitor 1 (RNH1) is a ubiquitously expressed protein that binds to and inhibits pancreatic-type ribonucleases. Here, we report that RNH1 binds to ribosomes and regulates erythropoiesis by controlling translation of the erythroid transcription factor GATA1. Rnh1-deficient mice die between embryonic days E8.5 and E10 due to impaired production of mature erythroid cells from progenitor cells. In Rnh1-deficient embryos, mRNA levels of Gata1 are normal, but GATA1 protein levels are decreased. At the molecular level, we found that RNH1 binds to the 40S subunit of ribosomes and facilitates polysome formation on Gata1 mRNA to confer transcript-specific translation. Further, RNH1 knockdown in human CD34+ progenitor cells decreased erythroid differentiation without affecting myelopoiesis. Our results reveal an unsuspected role for RNH1 in the control of GATA1 mRNA translation and erythropoiesis

Aspirin as an adjuvant treatment for cancer:feasibility results from the Add-Aspirin randomised trial

BACKGROUND: Preclinical, epidemiological, and randomised data indicate that aspirin might prevent tumour development and metastasis, leading to reduced cancer mortality, particularly for gastro-oesophageal and colorectal cancer. Randomised trials evaluating aspirin use after primary radical therapy are ongoing. We present the pre-planned feasibility analysis of the run-in phase of the Add-Aspirin trial to address concerns about toxicity, particularly bleeding after radical treatment for gastro-oesophageal cancer.METHODS: The Add-Aspirin protocol includes four phase 3 randomised controlled trials evaluating the effect of daily aspirin on recurrence and survival after radical cancer therapy in four tumour cohorts: gastro-oesophageal, colorectal, breast, and prostate cancer. An open-label run-in phase (aspirin 100 mg daily for 8 weeks) precedes double-blind randomisation (for participants aged under 75 years, aspirin 300 mg, aspirin 100 mg, or matched placebo in a 1:1:1 ratio; for patients aged 75 years or older, aspirin 100 mg or matched placebo in a 2:1 ratio). A preplanned analysis of feasibility, including recruitment rate, adherence, and toxicity was performed. The trial is registered with the International Standard Randomised Controlled Trials Number registry (ISRCTN74358648) and remains open to recruitment.FINDINGS: After 2 years of recruitment (October, 2015, to October, 2017), 3494 participants were registered (115 in the gastro-oesophageal cancer cohort, 950 in the colorectal cancer cohort, 1675 in the breast cancer cohort, and 754 in the prostate cancer cohort); 2719 (85%) of 3194 participants who had finished the run-in period proceeded to randomisation, with rates consistent across tumour cohorts. End of run-in data were available for 2253 patients; 2148 (95%) of the participants took six or seven tablets per week. 11 (0·5%) of the 2253 participants reported grade 3 toxicity during the run-in period, with no upper gastrointestinal bleeding (any grade) in the gastro-oesophageal cancer cohort. The most frequent grade 1-2 toxicity overall was dyspepsia (246 [11%] of 2253 participants).INTERPRETATION: Aspirin is well-tolerated after radical cancer therapy. Toxicity has been low and there is no evidence of a difference in adherence, acceptance of randomisation, or toxicity between the different cancer cohorts. Trial recruitment continues to determine whether aspirin could offer a potential low cost and well tolerated therapy to improve cancer outcomes.FUNDING: Cancer Research UK, The National Institute for Health Research Health Technology Assessment Programme, The MRC Clinical Trials Unit at UCL.</p

Predicting intention to treat HIV-infected patients among Tanzanian and Sudanese medical and dental students using the theory of planned behaviour - a cross sectional study

<p>Abstract</p> <p>Background</p> <p>The HIV epidemic poses significant challenges to the low income countries in sub Saharan Africa (SSA), affecting the attrition rate among health care workers, their level of motivation, and absenteeism from work. Little is known about how to deal with deterioration of human resources in the health care systems. This study aimed to predict the intention to provide surgical treatment to HIV infected patients among medical- and dental students in Tanzania and Sudan using an extended version of the Theory of Planned Behaviour (TPB).</p> <p>Methods</p> <p>Four hundred and seventy five medical- and dental students at the University of Dar es Salaam (mean age, 25 yr) and 642 dental students attending 6 public and private dental faculties in Khartoum (mean age 21.7 yr) completed self-administered TPB questionnaires in 2005 and 2007, respectively.</p> <p>Results</p> <p>Both Tanzanian and Sudanese students demonstrated strong intentions to provide care for people with HIV and AIDS. Stepwise linear regression revealed that the TPB accounted for 51% (43% in Tanzania and Sudan) of the variance in intention across study sites. After having controlled for country and past behaviour, the TPB in terms of attitudes, subjective norms and perceived behavioural control accounted for 34% and moral norms for an additional 2,3% of the explainable variance in intention. Across both study sites, attitudes were the strongest predictor of intention followed in descending order by subjective norms, moral norms and perceived behavioural control.</p> <p>Conclusion</p> <p>The TPB is applicable to students' care delivery intentions in the context of HIV and AIDS across the two SSA countries investigated. It is suggested that attitudes, subjective norms, moral norms and perceived behavioural control are key factors in students' willingness to treat AIDS and HIV infected patients and should be targets of interventions aimed at improving the quality of health care delivery in this context.</p
