Advances in e-learning in undergraduate clinical medicine: a systematic review.

BACKGROUND: E-learning is recognised as a useful educational tool and is becoming more common in undergraduate medical education. This review aims to examine the scope and impact of e-learning interventions on medical student learning in clinical medicine, in order to aid medical educators when implementing e-learning strategies in programme curricula. METHODS: A systematic review compliant with PRISMA guidelines that appraises study design, setting and population, context and type of evaluations. Specific search terms were used to locate articles across nine databases: MEDLINE/PubMed, ScienceDirect, EMBASE, Cochrane Library, ERIC, Academic Search Complete, CINAHL, Scopus and Google Scholar. Only studies evaluating e-learning interventions in undergraduate clinical medical education between January 1990 and August 2021 were selected. Of the 4,829 papers identified by the search, 42 studies met the inclusion criteria. RESULTS: The 42 studies included varied in scope, cognitive domain, subject matter, design, quality and evaluation. The most popular approaches involved multimedia platforms (33%) and case-based approaches (26%), were interactive (83%), asynchronous (71%) and accessible from home (83%). Twelve studies (29%) evaluated usability, all of which reported positive feedback. Competence in use of technology, high motivation and an open attitude were key characteristics of successful students and preceptors. CONCLUSIONS: Medical education is evolving consistently to accommodate rapid changes in therapies and procedures. In today's technologically adept world, e-learning is an effective and convenient pedagogical approach for the teaching of undergraduate clinical medicine.

Antimicrobial therapies for prevention of recurrent acute exacerbations of COPD (AECOPD): beyond the guidelines.

BACKGROUND: Unfortunately, many COPD patients continue to exacerbate despite good adherence to GOLD Class D recommended therapy. Acute exacerbations lead to an increase in symptoms, decline in lung function and increased mortality rate. The purpose of this review is to do a literature search for any prophylactic anti-microbial treatment trials in GOLD class D patients who 'failed' recommended therapy and discuss the role of COPD phenotypes, lung and gut microbiota and co-morbidities in developing a tailored approach to anti-microbial therapies for high frequency exacerbators. MAIN TEXT: There is a paucity of large, well-conducted studies in the published literature to date. Factors such as single-centre, study design, lack of well-defined controls, insufficient patient numbers enrolled and short follow-up periods were significant limiting factors in numerous studies. One placebo-controlled study involving more than 1000 patients, who had 2 or more moderate exacerbations in the previous year, demonstrated a non-significant reduction in exacerbations of 19% with 5 day course of moxifloxacillin repeated at 8 week intervals. In Pseudomonas aeruginosa (Pa) colonised COPD patients, inhaled antimicrobial therapy using tobramycin, colistin and gentamicin resulted in significant reductions in exacerbation frequency. Viruses were found to frequently cause acute exacerbations in COPD (AECOPD), either as the primary infecting agent or as a co-factor. However, other, than the influenza vaccination, there were no trials of anti-viral therapies that resulted in a positive effect on reducing AECOPD. Identifying clinical phenotypes and co-existing conditions that impact on exacerbation frequency and severity is essential to provide individualised treatment with targeted therapies. The role of the lung and gut microbiome is increasingly recognised and identification of pathogenic bacteria will likely play an important role in personalised antimicrobial therapies. CONCLUSION: Antimicrobial therapeutic options in patients who continue to exacerbate despite adherence to guidelines-directed therapy are limited. Phenotyping patients, identification of co-existing conditions and assessment of the microbiome is key to individualising antimicrobial therapy. Given the impact of viruses on AECOPD, anti-viral therapeutic agents and targeted anti-viral vaccinations should be the focus of future research studies.

Management of Bone Fragility in Primary Care in Ireland.

This study evaluated the prevention of bone fragility fractures in a representative sample of four Irish general practices. The clinical records of 243 patients potentially at risk of bone fragility were studied. One hundred and fourteen (47%) had a dual energy x-ray absorptiometry (DEXA) scan. Osteoporosis was established in 42 (17%) and osteopaenia in 28 (11%). One hundred and fifty-two (63%) were currently being prescribed bisphosphonates. Thirty-four (22%) of those on bisphosphonates did not have a baseline DEXA scan performed prior to commencing treatment and further analysis did not show a clear rationale for initiation of the treatment in this group of patients. Forty-six (30%) patients on bisphosphonates had been prescribed them for over 5 years without any apparent review to see if they were still indicated. There was no record of any of the practices having carried out a fracture risk score assessment prior to commencing bone fragility treatment. The implications are that bone fragility management warrants urgent review.

Adherence to COPD management guidelines in general practice? A review of the literature.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a progressive illness that is mostly managed in the general practice setting. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines are the international gold standard, and it is important to understand how these are being applied in general practice. AIMS: This review aimed to assess the current level of adherence to international best practice guidelines among general practitioners in relation to COPD. METHODS: PubMed and EMBASE searches (from 2012 to 2016) were performed and used the search terms guidelines, COPD, general practitioners, and primary care. Papers were excluded if they were not primary sources, were published before 2012, or did not pertain to a general practice setting. RESULTS: After applying set inclusion and exclusion criteria, 11 studies were retrieved. These papers were grouped under three categories: diagnosis, pharmacological, and non-pharmacological management, based on the GOLD guidelines. CONCLUSIONS: Current studies show significant variability in adherence to the GOLD guidelines. Barriers identified include lack of clarity, unfamiliarity with recommendations, and lack of familiarity with the guidelines. If general practice is expected to manage COPD and other chronic diseases, health service investment is needed to provide appropriate focused guidelines, to support their dissemination and resources to implement them in practice.

Food Allergy Emergencies in Children - To what extent are Early Years Services Prepared? A cross-sectional survey.

Food allergies are common in preschool children. This study's aims are to establish prevalence, to clarify management practices, levels of preparedness and the perceived role of General Practitioners amongst Early Years Services providers. This study is an anonymous, quantitative, cross sectional study. An online questionnaire was distributed to 282 Early Years Service providers. Data were analysed using SPSS. Response rate was 35% (n=98). Prevalence of food allergy was 3% (n=119). Allergic reactions to food had occurred on site in 16% (n=15). Written emergency action plans were available in 47% of facilities (n=46). Medications were not kept on site in 63% (n=62) of facilities. General practitioners were felt to have an important role in the management of food allergies by 76% of respondents (n=61). This study identifies significant areas for improvement in the management of food allergic child in Early Years Services.

An evaluation of community-based cognitive stimulation therapy: a pilot study with an Irish population of people with dementia.

OBJECTIVES: Research shows that cognitive stimulation therapy (CST) improves cognitive function, quality of life, and well-being of people with mild-moderate dementia. Despite consistent evidence and recommendations, CST is not routinely available in Ireland post-diagnosis. The aim of the current research was to develop and evaluate community-based CST for people with mild-moderate dementia, run by the Alzheimer Society of Ireland across four pilot sites in Ireland. METHODS: Participants with mild-moderate dementia attended once weekly CST sessions for 14 weeks. Baseline and post-intervention assessments were completed by CST participants, carers, and CST facilitators. Primary outcomes of interest for CST participants included quality of life (Quality of Life in Alzheimer Disease Scale), cognitive function (Montreal Cognitive Assessment), and subjective cognitive function (Memory Awareness Rating Scale-Functioning Subscale). Secondary outcomes included well-being, cognitive ability, satisfaction with cognitive performance, and engagement and confidence of CST participants; well-being of carers; and job satisfaction of facilitators. Post-intervention interviews supplemented quantitative analyses. RESULTS: In total, 20 CST participants, 17 carers, and six CST facilitators completed evaluation assessments. Results showed that CST improved participants' satisfaction with cognitive performance (p=0.002), level of engagement (p=0.046), level of confidence (p=0.026). Improvements on subjective cognitive function just fell short of significance (p=0.055). Qualitative analysis of interview data identified consistent themes of cognitive and overall benefits of CST; and provided support for quantitative data. CONCLUSIONS: Community-based CST positively impacted the lives of people with dementia and their families. This study supports prior recommendations that CST should be made routinely available to people with mild-moderate dementia, particularly in light of the lack of post-diagnostic interventions currently offered in Ireland.

A decade of domiciliary non-invasive ventilation in the west of Ireland.

BACKGROUND: While domiciliary non-invasive ventilation (NIV) was initially used in the treatment of respiratory failure resulting from chest wall deformity, the main indication is now chronic obstructive pulmonary disease (COPD) with recurrent exacerbations associated with type 2 respiratory failure. A longitudinal study of domiciliary NIV provides insights into the evolution of this treatment in the west of Ireland. METHODS: The cohort of patients receiving new prescriptions for domiciliary NIV from Galway University Hospital from 2000 to 2012 was reviewed using study coordinator chart reviews and telephone follow-ups. RESULTS: In total, 161 patients were identified. Prescriptions for domiciliary NIV increased from 2 in 2000 to 35 in 2012. The most common indication between 2000 and 2006 was obesity hypoventilation syndrome (OHS), changing to COPD between 2007 and 2012. There were significantly higher mortality rates in COPD and neuromuscular disease at 1- and 3-year follow-up compared to OHS and chest wall disease. Patients with chest wall disease had most survival years (7.33 ± 5.51) following initiation of domiciliary NIV when compared to patients with OHS (5.50 ± 3.70) and COPD (3.03 ± 1.89) and patients with neuromuscular disease (2.50 ± 2.01). CONCLUSIONS: Domiciliary NIV use increased significantly in the West of Ireland from 2000 to 2012. There has been a shift in prescribing toward COPD. Survival rates for COPD on NIV are relatively short in contrast to patients with OHS and chest wall disease. Improved understanding of the benefits of NIV will allow physicians to better determine appropriate and cost-effective use in the future.

Radon testing in rapid access lung clinics: an opportunity for secondary prevention.

BACKGROUND: Radon is a naturally occurring radioactive gas and a level 1 carcinogen. It acts synergistically with cigarette smoke to cause lung cancer. In Ireland, radon is estimated to be associated with 13 % of all lung cancers. Rapid access lung cancer clinics (RALC's) were established in the UK and Ireland to improve lung cancer management outcomes. There has been no attempt to date to provide advice on household radon exposure assessments in this setting. AIMS: We performed a prospective feasibility study of radon assessment in our RALC to test the hypothesis that patients would avail of this service and that it would provide an opportunity for secondary prevention in at risk persons. METHODS: We investigated household radon levels in consecutive patients who were newly referred with symptoms of lung cancer to the RALC in Galway University Hospital, Ireland over a 6-month period. RESULTS: Of 50 patients enrolled, 42 returned valid results. Overall 21 % of patients had radon levels recorded above the national reference level. Only 5 % of patients were aware of the association between radon gas and lung cancer. Smokers were significantly less likely to engage fully in radon testing. CONCLUSIONS: The development of RALC's offers a novel opportunity to integrate the concepts of radon exposure, cigarette smoking and the development of lung cancer, and to reinforce this message in the minds of at risk patients.

Serum fibroblastic growth factor 23 in acute Sarcoidosis and normal kidney function.

BACKGROUND: Serum fibroblastic growth factor (FGF) 23 has recently been established as a major physiological regulator of phosphate homeostasis and may have a causal role in adverse cardiovascular and bone outcomes. However its role in states of disordered phosphate homeostasis and normal kidney function is as yet under characterised. AIMS: To investigate whether this biomarker of vascular calcification and adverse bone outcomes is detectable in patients with sarcoidosis. DESIGN: We conducted a cross sectional study on a convenience sample of patients presenting with acute sarcoidosis to a respiratory tertiary referral unit. METHODS: We set out to systematically examine the characteristics and determinants of serum FGF-23 in patients presenting with acute sarcoidosis. RESULTS: We studied 39 patients, 26 were male. Mean (SD) age was 33 (9.6) years. 15.4% of patients had a serum level of FGF-23 ≥ 9.9 pg/mL. The remaining 84.6% of patients had a serum FGF-23 < 9.9 pg/mL. Those with a detectable serum FGF-23 had a significantly higher serum calcium (P = 0.007), and lower serum iPTH (P<0.001). Serum phosphate and 25-hydroxyvitamin D were not statistically significantly different between groups (P=0.25 and P=0.83). The proportion of patients with stage II disease on CXR was higher in those with a detectable FGF-23 (P<0.001). CONCLUSIONS: Serum FGF-23 was below the level of detection in the majority of this cohort of patients presenting with acute sarcoidosis. A detectable serum FGF-23 was associated with a higher serum calcium and lower serum iPTH.

Educational interventions: equipping general practice for youth mental health and substance abuse. A discussion paper.

BACKGROUND: Youth mental health issues and substance abuse are important causes of morbidity and mortality in Ireland. General practice is a frequent point of contact for young people, however, reluctance amongst this population group to disclose mental health issues and a lack of confidence amongst GPs in dealing with them have been reported. Focussed training interventions with formal evaluation of their acceptability and effectiveness in achieving learning, behavioural change and impact on clinical practice are needed. AIMS: This paper aims to examine the literature on general practice in youth mental health, specifically, factors for an educational intervention for those working with young people in the community. METHODS: This review paper was carried out by an online search of PubMed on the recent literature on mental health and on educational interventions for health care workers in primary care. RESULTS: A number of papers describing educational interventions for GPs and primary care workers were found and analysed. Key areas to be addressed when identifying and treating mental health problems were prevention, assessment, treatment, interaction with other services and ongoing support. Important elements of an educational intervention were identified. DISCUSSION: Several barriers exist that prevent the identification and treatment of these problems in primary care. An educational intervention should help GPs address these issues. Any intervention should be rigorously evaluated. CONCLUSION: With the shift in services to the community in Irish health policy, the GP with appropriate training could take the lead in early intervention in youth mental health and addiction.

Development and evaluation of an educational intervention in youth mental health for primary care practitioners.

OBJECTIVES: Irish adolescents have one of the highest rates of suicide and self-harm in the European Union. Although primary care has been identified as an opportune environment in which to detect and treat mental health problems in adolescents, lack of training among primary care professionals (PCPs) is a barrier to optimum identification and treatment. We describe the development and evaluation of an educational intervention on youth mental health and substance misuse for PCPs. METHODS: Thirty general practitioners and other PCPs working in the Mid-West region participated in an educational session on youth-friendly consultations, and identification and treatment of mental ill-health and substance use. Learning objectives were addressed through a presentation, video demonstration, small group discussions, role play, question-and-answer sessions with clinical experts, and an information pack. Following the session, participants completed an evaluation form assessing knowledge gain and usefulness of different components of the session. RESULTS: A total of 71% of participants were involved in the provision of care to young people and 55% had no previous training in youth mental health or substance abuse. Participants rated knowledge gains as highest with regard to understanding the importance of early intervention, and primary care, in youth mental health. The components rated as most useful were case studies/small group discussion, the 'question-and-answer session' with clinical experts, and peer interaction. CONCLUSIONS: The educational session outlined in this pilot was feasible and acceptable and may represent an effective way to train professionals to help tackle the current crisis in youth mental health.

Radiological remission and recovery of thirst appreciation after infliximab therapy in adipsic diabetes insipidus secondary to neurosarcoidosis.

BACKGROUND: Neurosarcoidosis is a rare and aggressive variant of systemic sarcoidosis which may result in hypothalamic-pituitary dysfunction. We report a case of hypothalamic hypopituitarism secondary to neurosarcoidosis complicated by adipsic diabetes insipidus (ADI). Initiation of anti-tumour necrosis factor-α (TNF-α) therapy resulted in both radiological disease remission and recovery of osmoregulated thirst appreciation after 3 months. CASE SUMMARY: A 22-year-old man was referred to the endocrinology service with profound weight gain, polyuria and lethargy. Biochemical testing confirmed anterior hypopituitarism while posterior pituitary failure was confirmed by hypotonic polyuria responding to desmopressin. Magnetic resonance imaging (MRI) demonstrated extensive hypothalamic infiltration; neurosarcoidosis was confirmed histologically after excisional cervical lymph node biopsy. Osmoregulated thirst appreciation was normal early in the disease course despite severe hypotonic polyuria. However, subsequent subjective loss of thirst appreciation and development of severe hypernatraemia in the setting of normal cognitive function indicated onset of ADI. MANAGEMENT: Clinical management involved daily weighing, regular plasma sodium measurement, fixed daily fluid intake and oral desmopressin. We initiated immunosuppressive therapy with pulsed intravenous anti-TNF-α therapy (infliximab) after multidisciplinary team consultation. OUTCOME: Infliximab therapy resulted in successful radiological disease remission and complete recovery of osmoregulated thirst appreciation. This was confirmed by subjective return of thirst response and maintenance of plasma sodium in the normal range in the absence of close biochemical monitoring.

Towards vertical integration in general practice education: literature review and discussion paper.

BACKGROUND: Medical education policy in Ireland has enabled an increase in undergraduate and postgraduate education activity in general practice. Internationally, 'vertical integration in general practice education' is suggested as a key strategy to support the implementation of this policy development. AIMS: To review the emerging literature on vertical integration in GP education, specifically to define the concept of 'vertical integration' with regard to education in general practice and to describe its benefits and challenges. METHODS: We searched 'Pubmed', 'Academic Search Complete', 'Google', and 'MEDLINE' databases using multiple terms related to 'vertical integration' and 'general practice education' for relevant articles published since 2001. Discussion papers, reports, policy documents and position statements were identified from reference lists and retrieved through internet searches. RESULTS: The key components of 'vertical integration' in GP education include continuous educational pathway, all stages in GP education, supporting the continuing educational/professional development needs of learners at each stage and effective curriculum planning and delivery. Many benefits (for GPs, learners and the community) and many challenges (for GPs/practices, learners and GPs in training) have been described. Characteristics of successful implementation include role sharing and collaborative organisational structures. CONCLUSIONS: Recent developments in medical education in Ireland, such as the increase in medical school clinical placements in general practice and postgraduate GP training and the introduction of new competence assurance requirements offer an important opportunity to further inform how vertical integration can support increased educational activity in general practice. Describing this model, recognising its benefits and challenges and supporting its implementation in practice are priorities for medical education in Ireland.

Pretreatment of endothelial progenitor cells with osteopontin enhances cell therapy for peripheral vascular disease.

Tissue necrosis resulting from critical limb ischemia (CLI) leads to amputation in a significant number of patients. Autologous cell therapy using angiogenic cells such as endothelial progenitor cells (EPCs) holds promise as a treatment for CLI but a limitation of this treatment is that the underlying disease etiology that resulted in CLI may also contribute to dysfunction of the therapeutic EPCs. This study aimed to elucidate the mechanism of EPC dysfunction using diabetes mellitus as a model and to determine whether correction of this defect in dysfunctional EPCs ex vivo would improve the outcome after cell transplantation in the murine hind limb ischemia model. EPC dysfunction was confirmed in a homogenous population of patients with type 1 diabetes mellitus and a microarray study was preformed to identify dysregulated genes. Notably, the secreted proangiogenic protein osteopontin (OPN) was significantly downregulated in diabetic EPCs. Furthermore, OPN-deficient mice showed impaired recovery following hind limb ischemia, suggesting a critical role for OPN in postnatal neovascularization. EPCs isolated from OPN KO mice showed decreased ability to adhere to endothelial cells as well as impaired angiogenic potential. However, this dysfunction was reversed upon exposure to recombinant OPN, suggesting that OPN may act in an autocrine manner on EPCs. Indeed, exposure of OPN knockout (KO) EPCs to OPN was sufficient to induce the secretion of angiogenic proteins (IL-6, TGF-α, and FGF-α). We also demonstrated that vascular regeneration following hind limb ischemia in OPN KO mice was significantly improved upon injection of EPCs preexposed to OPN. We concluded that OPN acts in an autocrine manner on EPCs to induce the secretion of angiogenic proteins, thereby playing a critical role in EPC-mediated neovascularization. Modification of cells by exposure to OPN may improve the efficacy of autologous EPC transplantation via the enhanced secretion of angiogenic proteins.

Total intravenous anaesthesia with propofol and remifentanil for elective neurosurgical procedures: an audit of early postoperative complications.

BACKGROUND AND OBJECTIVES: This was a prospective audit to assess the incidence and characteristics of early postoperative complications in the recovery room in extubated patients after elective neurosurgical procedures using propofol and remifentanil-based total intravenous anaesthesia. METHODS: Vital signs (temperature, conscious level, respiratory rate, oxygen saturation, pulse and blood pressure) and postoperative complications (shivering, nausea, vomiting and cardiorespiratory) were analysed in 145 adult patients over a 1-yr period. RESULTS: The overall shivering, postoperative nausea and vomiting and postoperative hypertension (systolic blood pressure more than 25% of the preoperative value) incidences were 30.3%, 16.6% and 35.2%, respectively. Fifty-one percent of the patients had at least one of the above complications. The complication rates were found to be widely different among various types of neurosurgery. The surgical procedures were divided into five groups: supratentorial craniotomy, posterior fossa craniotomy, intracranial vascular procedures, transphenoidal hypophysectomy and extracranial procedures. Median extubation time was similar in all groups and patients were fully conscious with no hypoxia in the recovery room. The intracranial vascular group had the highest shivering and postoperative nausea and vomiting rates (58.8% and 29.4%, respectively). In the supratentorial craniotomy group, 46% of the patients had hypertension. The overall complication rate (presence of any complications) was highest in the supratentfial craniotomy (55.4%), posterior fossa craniotomy (75%) and intracranial vascular (76.5%) groups. Shivering and overall complication rate was significantly related to the anaesthetic time (P
