RESUMEN

Co-creation of education within the context of student inclusion alongside diverse stakeholders merits exploration. We studied the perspectives of students and teachers from different institutions who participated in co-creating a transition to residency curriculum. We conducted post-hoc in-depth interviews with 16 participants: final-year medical students, undergraduate, and postgraduate medical education stakeholders who were involved in the co-creation sessions. Findings build on the Framework of Stakeholders' Involvement in Co-creation and identify the four key components of co-creation with diverse faculty: immersion in positive feelings of inclusivity and appreciation, exchange of knowledge, engagement in a state of reflection and analysis, and translation of co-creation dialogues into intended outcomes. Despite power dynamics, participants valued open communication, constructive feedback, mutual respect, and effective moderation. The study broadened our understanding of the co-creation process in diverse stakeholder settings. Incorporating key elements in the presence of power relations can enrich co-creation by leveraging wider expertise.

RESUMEN

PURPOSE: Medical students' transition to postgraduate training, given the complexity of new roles and responsibilities, requires the engagement of all involved stakeholders. This study aims to co-create a transition curriculum and determine the value of involving the key stakeholders throughout such transition in its design process. METHODS: We conducted a mixed-methods study involving faculty/leaders (undergraduate/postgraduate), final-year medical students, and chief residents. It commenced with eight co-creation sessions (CCS), qualitative results of which were used to draft a quantitative survey sent to non-participants, followed by two consensus-building CCS with the original participants. We applied thematic analysis for transcripts of all CCS, and mean scores with standard deviations for survey analysis. RESULTS: We identified five themes: adaptation, authenticity, autonomy, connectedness, and continuity, embedded in the foundation of a supportive environment, to constitute a Model of Learning during Transition (MOLT). Inclusion of various stakeholders and optimizing their representation brought rich perspectives to the design process. This was reinforced through active students' participation enabling a final consensus. CONCLUSIONS: Bringing perspectives of key stakeholders in the transition spectrum enriches transition curricula. The proposed MOLT can provide a guide for curriculum designers to optimize the final year of undergraduate medical training in preparing students for postgraduate training with essential competencies to be trained.

RESUMEN

BACKGROUND: Though common practice in Europe, few studies have described the efficacy of early clinical exposure (ECE) in the Middle East. The barriers to clinical learning experienced by these novice medical students have not been reported. This evaluation reports on introducing ECE in primary care, supported by Experiential Review (ER) debriefing sessions. The evaluation explores students' experiences of their acquisition of clinical and non-technical skills, sociocultural issues commonly encountered but underreported and barriers to clinical learning experienced. METHODS: We conducted a cross-sectional study of three student cohorts in 2017-19: All second and third-year students at the new College of Medicine were invited to participate. The primary outcome was students' perceptions of the aims of the Primary Health Centre Placement (PHCP) programme and how it facilitated learning. Secondary outcome measures were students' perceptions of their learning in ER sessions and perceived barriers to learning during PHCPs. Student perceptions of the PHCPs were measured using a Likert scale-based questionnaire. RESULTS: One hundred and fifty-one students participated: 107 in year 2 and 44 in year 3; 72.3% were female. Overall, most students (> 70%) strongly agreed or agreed with the purposes of the PCHPs. Most students (71%) strongly agreed or agreed that the PCHPs allowed them to learn about patient care; 58% to observe doctors as role models and 55% to discuss managing common clinical problems with family physicians. Most students (year 2 = 62.5% and year 3 = 67%) strongly agreed/agreed that they were now confident taking histories and examining patients. Student barriers to clinical learning included: Unclear learning outcomes (48.3%); faculty too busy to teach (41.7%); lacking understanding of clinical medicine (29.1%); shyness (26.5%); and finding talking to patients difficult and embarrassing (25.8%). Over 70% reported that ER enabled them to discuss ethical and professional issues. CONCLUSIONS: Overall, our Middle Eastern students regard ECE as beneficial to their clinical learning. PHCPs and ER sessions together provide useful educational experiences for novice learners. We recommend further exploration of the barriers to learning to explore whether these novice students' perceptions are manifesting underlying cultural sensitivities or acculturation to their new environment.

RESUMEN

Health professions programs heavily depend on experiential learning to prepare learners for practice within the healthcare system. Learners acquire a significant proportion of patient care skills as they participate in experiential learning activities. As the coronavirus disease 2019 (COVID-19) pandemic disrupts education globally, educators have been challenged to reexamine existing teaching approaches to minimize the impact on experiential educational outcomes. This article describes how educators from the College of Pharmacy and College of Medicine at Qatar University utilized nontraditional teaching methods to ensure the continuation of experiential learning despite the disruption due to the pandemic.

RESUMEN

OBJECTIVES: To explore patient and provider illness perceptions and barriers to effective management of gout in general practice. DESIGN AND SETTING: A qualitative study involving semistructured face-to-face interviews with patients and health professionals from 25 Nottinghamshire general practices and one central National Health Service hospital. PARTICIPANTS: Twenty gout sufferers and 18 health professionals (six general practitioners, five hospital physicians, seven practice nurses). RESULTS: A number of key themes emerged suggesting that several factors impact on patients' access to recommended treatments. The main barriers were patient experiences and lay beliefs of their condition which affected seeking advice and adherence to treatment. There was universal lack of knowledge and understanding of the causes and consequences of gout and that it can be treated effectively by lifestyle change and use of urate lowering therapy (ULT). All participants associated gout with negative stereotypical images portrayed in Victorian cartoons. Many viewed it as self-inflicted or part of ageing and only focused on managing acute attacks rather than treating the underlying cause. The main provider barriers that emerged related to health professionals' lack of knowledge of gout and management guidelines, reflected in the suboptimal information they gave patients and their reluctance to offer ULT as a 'curative' long-term management strategy. CONCLUSION: There are widespread misconceptions and lack of knowledge among both patients and health professionals concerning the nature of gout and its recommended management, which leads to suboptimal care of the most common inflammatory joint disease and the only one for which we have 'curative' treatment.

RESUMEN

AIM: To establish two scoring models for identifying individuals at risk of developing Impaired Glucose Metabolism (IGM) or Type two Diabetes Mellitus (T2DM) in Qatari. MATERIALS AND METHODS: A sample of 2000 individuals, from Qatar BioBank, was evaluated to determine features predictive of T2DM and IGM. Another sample of 1000 participants was obtained for external validation of the models. Several scoring models screening for T2DM were evaluated and compared to the model proposed by this study. RESULTS: Age, gender, waist-to-hip-ratio, history of hypertension and hyperlipidemia, and levels of educational were statistically associated with the risk of T2DM and constituted the Qatar diabetes mellitus risk score (QDMRISK). Along with, the 6 aforementioned variables, the IGM model showed that BMI was statistically significant. The QDMRISK performed well with area under the curve (AUC) 0.870 and .815 in the development and external validation cohorts, respectively. The QDMRISK showed overall better accuracy and calibration compared to other evaluated scores. The IGM model showed good accuracy and calibration, with AUCs .796 and .774 in the development and external validation cohorts, respectively. CONCLUSIONS: This study developed Qatari-specific diabetes and IGM risk scores to identify high risk individuals and can guide the development of a nationwide primary prevention program.

RESUMEN

INTRODUCTION: Experiential learning is the backbone of many health care professional education programs; however, the quality of learning is profoundly dependent on the skills and experiences of clinical preceptors. This study was conducted at Qatar University Health Cluster (Colleges of Pharmacy, Medicine, and Health Sciences) with the primary objective of identifying the educational needs of preceptors to design and review an educational professional development program. METHODS: This study adopted a mixed-methods approach and was conducted in three stages: (1) assessment of preceptor educational needs, (2) designing of the Practice Educators' Academy program, and (3) revision and refinement of the designed program. The needs' assessment was conducted at all the three colleges through a validated survey and focus groups comprising of preceptors, students, and clinical faculty members. The sample included 209 survey respondents and 11 focus group sessions. RESULTS: The results yielded five key themes and a variety of individual preferences, which were used to design a five-module face-to-face two-day interactive workshop. For the revision of the designed program, the syllabus was shared purposively with selected scholars and experts in the area of health professions education, and their feedback was collected and critically examined. Furthermore, the refinement of the program was performed on the basis of this feedback, resulting in the revised and representative program being ready for piloting. DISCUSSION: A preceptor development program on experiential teaching and learning skills was successfully designed and revised with the needs of the clinical preceptors at its core. Preceptors' skills development can advance health care outcomes by preparing competent health professional graduates.

RESUMEN

INTRODUCTION: In Europe, pharmacists may be an important first point of contact for men with erectile dysfunction (ED) asking for advice and treatment. AIM: To determine if European community pharmacists could appropriately recommend suitability for supply of sildenafil 50 mg for the treatment of ED. METHODS: For this cross-sectional, observational study, the current Summary of Product Characteristics was adapted to create a study drug information sheet for use in a pharmacy setting in which, for certain patients, supply is not suitable and referral to a physician is recommended. After training and with use of a guidance questionnaire, pharmacists assessed the suitability of supply of sildenafil 50 mg for men presenting to their pharmacy. Men with self-reported ED who were not currently using a phosphodiesterase type 5 inhibitor were recruited. Within 7 days of the pharmacist-patient interaction, a physician with experience in the management of ED telephoned the subject to assess suitability. If there was discordance between the pharmacist and physician recommendations, the case was independently reassessed by a physician specialist in sexual medicine. MAIN OUTCOME MEASURES: The primary end point was the concordance rate (with 95% confidence intervals) between pharmacist and physician recommendations. Rates were weighted by country sample sizes. RESULTS: Concordance (95% confidence interval) was 0.70 (0.66-0.74) between pharmacist and physician recommendation, indicating agreement in 70% of cases, and was 0.90 (0.86-0.94) between pharmacist and physician specialist in sexual medicine. Furthermore, if the cases in which the pharmacist did not put subjects at risk (i.e., gave an acceptable recommendation) are assessed, the success rate is 83.5% (79.6-87.4%) and 92.8% (90.1-95.5%), respectively. CONCLUSION: Pharmacists were accurate in providing suitable treatment recommendation, generally not recommending sildenafil for men without ED and recommending physician assessment when there was any question about cardiovascular health, other comorbidity, or co-medication.

RESUMEN

BACKGROUND: The Individualised Neuromuscular Quality of Life (INQoL) questionnaire is a published muscle disease specific measure of QoL that has been validated using both qualitative and quantitative methods in a United Kingdom population of adults with muscle disease. If INQoL is to be used in other countries it needs to be linguistically and culturally validated for those countries. It may be important to understand any cultural differences in how patients rate their QoL when applying QoL measures in multi-national clinical trials. METHODS: We conducted a postal survey of QoL issues in US adults with muscle disease using an agreed translation, from UK to US English, of the same questionnaire as was used in the original construction of INQoL. This questionnaire included an opportunity for free text comments on any aspects of QoL that might not have been covered by the questionnaire. We examined the responses using both quantitative and qualitative approaches. The frequency of the responses in US versus UK populations was compared using appropriate correlation tests and Rasch analysis. A phenomenological approach was used to guide the qualitative analysis and facilitate the exploration of patients' perceptions and experiences. RESULTS: The US survey received 333 responses which were compared with 251 UK survey responses.We found that INQoL domains covered all the issues raised by US subjects with no additional domains required. The experiences of those with muscle disease were remarkably similar in the US and UK but there were differences related to the impact of muscle disease on relationships and on employment which was greater for those living in the United States. The greater impact on employment was associated with a higher importance rating given to employment in the US. This may reflect the lower level of financial support for those who are unemployed, and the loss of employment related health benefits. CONCLUSIONS: INQoL is appropriate for use in US population but there may be differences in the importance that US subject attach to certain aspects of QoL that could be the basis for further study.If these differences are confirmed then this may have implications for the interpretation of QoL outcomes in multi-national trials.

RESUMEN

Clinical problem solving tests (CPSTs) have been shown to be reliable and valid for recruitment to general practice (GP) training programmes. This article presents the results from a Department of Health-funded pilot into the use of a CPST designed for recruitment to the acute specialties (AS). The pilot paper consisted of 99 items from the validated GP question bank and 40 new items aimed specifically at topics of relevance to AS training. The CPST successfully differentiated between applicants. The overall test and the GP section showed high internal reliability, whereas the AS pilot section performed less well. A detailed item analysis revealed that the AS pilot items were, on average, more difficult and of poorer quality than the GP items. Important issues that need to be addressed in the early development phase of a test used for high stakes selection to specialty training programmes are discussed.

RESUMEN

Pressured by the enormous human and economic costs of the COVID-19 pandemic, certain countries and political figures have advocated the use of drugs and vaccines that did not go through the required regulatory stages of the development. Although the reason for bypassing these stages in a race to produce a treatment and vaccine for the COVID-19 patients could have been caused by good intentions to stop the human suffering from the pandemic, nonetheless, history has taught us that the results of this action could be catastrophic. In this article, we briefly review the lessons and tragedies in the evolution of human subject research regulations emphasizing the need for the proper evaluation of drugs and vaccines for COVID-19.

RESUMEN

AIMS: Published data on the clinical presentation of peripartum cardiomyopathy (PPCM) are very limited particularly from the Middle East. The aim of this study was to examine the clinical presentation, management, and outcomes of patients with PPCM using data from a large multicentre heart failure (HF) registry from the Middle East. METHODS AND RESULTS: From February to November 2012, a total of 5005 consecutive patients with HF were enrolled from 47 hospitals in 7 Middle East countries. From this cohort, patients with PPCM were identified and included in this study. Clinical features, in-hospital, and 12 months outcomes were examined. During the study period, 64 patients with PPCM were enrolled with a mean age of 32.5 ± 5.8 years. Family history was identified in 11 patients (17.2%) and hypertension in 7 patients (10.9%). The predominant presenting symptom was dyspnoea New York Heart Association class IV in 51.6%, class III in 31.3%, and class II in 17.2%. Basal lung crepitations and peripheral oedema were the predominant signs on clinical examination (98.2% and 84.4%, respectively). Most patients received evidence-based HF therapies. Inotropic support and mechanical ventilation were required in 16% and 5% of patients, respectively. There was one in-hospital death (1.6%), and after 1 year of follow-up, nine patients were rehospitalized with HF (15%), and one patient died (1.6%). CONCLUSIONS: A high index of suspicion of PPCM is required to make the diagnosis especially in the presence of family history of HF or cardiomyopathy. Further studies are warranted on the genetic basis of PPCM.

RESUMEN

BACKGROUND: Tumour-associated macrophages (TAMs) are often implicated in cancer progression but can also exert anti-tumour activities. Selective eradication of cancer-promoting (M2-like) TAM subsets is a highly sought-after goal. Here, we have devised a novel strategy to achieve selective TAM depletion, involving the use of T cell engagers to direct endogenous T cell cytotoxicity towards specific M2-like TAMs. To avoid "on-target off-tumour" toxicities, we have explored localising expression of the T cell engagers to the tumour with enadenotucirev (EnAd), an oncolytic adenovirus in Phase I/II clinical trials. METHOD: A panel of bi- and tri-valent T cell engagers (BiTEs/TriTEs) was constructed, recognising CD3ε on T cells and CD206 or folate receptor ß (FRß) on M2-like macrophages. Initial characterisation of BiTE/TriTE activity and specificity was performed with M1- and M2-polarised monocyte-derived macrophages and autologous lymphocytes from healthy human peripheral blood donors. T cell engagers were inserted into the genome of EnAd, and oncolytic activity and BiTE secretion assessed with DLD-1 tumour cells. Clinically-relevant ex vivo models (whole malignant ascites from cancer patients) were employed to assess the efficacies of the free- and virally-encoded T cell engagers. RESULTS: T cells activated by the CD206- and FRß-targeting BiTEs/TriTEs preferentially killed M2- over M1-polarised autologous macrophages, with EC50 values in the nanomolar range. A TriTE with bivalent CD3ε binding - the first of its kind - demonstrated enhanced potency whilst retaining target cell selectivity, whereas a CD28-containing TriTE elicited non-specific T cell activation. In immunosuppressive malignant ascites, both free and EnAd-encoded T cell engagers triggered endogenous T cell activation and IFN-γ production, leading to increased T cell numbers and depletion of CD11b+CD64+ ascites macrophages. Strikingly, surviving macrophages exhibited a general increase in M1 marker expression, suggesting microenvironmental repolarisation towards a pro-inflammatory state. CONCLUSIONS: This study is the first to achieve selective depletion of specific M2-like macrophage subsets, opening the possibility of eradicating cancer-supporting TAMs whilst sparing those with anti-tumour potential. Targeted TAM depletion with T cell engager-armed EnAd offers a powerful therapeutic approach combining direct cancer cell cytotoxicity with reversal of immune suppression.

RESUMEN

Epidemiological studies investigating seroprevalence of vaccine preventable infections at both individual and population level are important in guiding screening and vaccination practices. Data on seroprevalence of common vaccine preventable infections in HIV-infected individuals is lacking. We carried out a retrospective cohort study to investigate serological immunity and factors associated with immunity to hepatitis A virus (HAV), hepatitis B virus (HBV) and varicalla virus (VZV) in a cohort of HIV-infected individuals attending a large ambulatory HIV specialist centre in Ireland. Basic demographic data including risk of acquisition of HIV and region of origin was recorded. Between-group prevalence was compared using the Chi2 test and Wilkoxin signed rank test. Univariate variables with p<0.2 were entered into a multivariate logistic regression model. Of 1287 HIV-infected individuals included in this study (median [SD] age 39 [10] years, 68% male, 46% Irish), 75% were hepatitis A IgG positive, 94% were VZV IgG positive, 3% were HBV surface antigen (sAg) positive while 29% were HBV core antibody (cAb) positive. This study identifies a significant proportion of HIV infected who were susceptible to common vaccine preventable infections. These results highlight the importance of proactive screening and immunization of HIV-infected individuals to ensure optimal protect ionagainst vaccine preventable diseases in this at risk patient group.

RESUMEN

Conventional wisdom suggests that assessment length is positively related to the rate at which applicants opt out of the assessment phase. However, restricting assessment length can negatively impact the utility of a selection system by reducing the reliability of its construct scores and constraining coverage of the relevant criterion domain. Given the costly nature of these tradeoffs, is it better for managers to prioritize (a) shortening assessments to reduce applicant attrition rates or (b) ensuring optimal reliability and validity of their assessment scores? In the present study, we use data from 222,772 job-seekers nested within 69 selection systems to challenge the popular notion that selection system length predicts applicant attrition behavior. Specifically, we argue that the majority of applicant attrition occurs very early in the assessment phase and that attrition risk decreases, not increases, as a function of time spent in assessment. Our findings supported these predictions, revealing that the majority of applicants who quit assessments did so within the first 20 min of the assessment phase. Consequently, selection system length did not predict rates of applicant attrition. In fact, when controlling for observed system length and various job characteristics, we found that systems providing more conservative (i.e., longer) estimates of assessment length produced lower overall attrition rates. Collectively, these findings suggest that efforts to curtail applicant attrition by shortening assessment length may be misguided. (PsycINFO Database Record

RESUMEN

RATIONALE, AIMS AND OBJECTIVES: Clinical practice guidelines often grade the 'strength' of their recommendations according to the robustness of the supporting research evidence. The existing methodology does not allow the strength of recommendation (SOR) to be upgraded for recommendations for which randomized controlled trials are impractical or unethical. The purpose of this study was to develop a new method of determining SOR, incorporating both research evidence and expert opinion. METHODS: A Delphi technique was employed to produce 10 recommendations for the role of exercise therapy in the management of osteoarthritis of the hip or knee. The SOR for each recommendation was determined by the traditional method, closely linked to the category of research evidence found on a systematic literature search, and on a visual analogue scale (VAS). Recommendations were grouped A-D according to the traditional SOR allocated and the mean VAS calculated. Difference across the groups was assessed by one-way ANOVA variance analysis. RESULTS: Mean VAS scores for the traditional SOR groups A-D and one proposition which was 'not recommended' showed significant linearity on one-way ANOVA. However, certain recommendations which, for practical reasons, could not assessed in randomized controlled trials and therefore could not be recommended strongly by the traditional methodology, were allocated a strong recommendation by VAS. CONCLUSIONS: This new system of grading strength of SOR is less constrained than the traditional methodology and offers the advantage of allowing SOR for procedures which cannot be assessed in RCTs for practical or ethical reasons to be upgraded according to expert opinion.
