The impact of a student-led anti-racism programme on medical students' perceptions and awareness of racial bias in medicine and confidence to advocate against racism

INTRODUCTION

Systemic racism impacts personal and community health; however, education regarding its role in perpetuating healthcare inequity remains limited in medical curricula. This study implemented and evaluated the impact of a student-led anti-racism programme on medical students' perceptions of racial bias in medicine, awareness of, and confidence to advocate against racism in medicine.

METHOD

A total of 543 early stage medical students were invited to participate in the programme. Participants were assigned readings and videos exploring racial injustice in medicine and attended a virtual small-group discussion facilitated by faculty and students. Online surveys were used to collect pre- and post-programme data using Likert scales for response items. Open-ended questions were independently reviewed by three authors using reflexive thematic analysis.

RESULTS

Sixty-three early-stage medical students enrolled in the programme, of which 42 completed the pre-programme survey. There was a 76% (n = 32) response rate for the post-programme survey. The majority of students (60%, n = 25) had no previous education about racism in medicine. From pre- to post-programme, there was a significant change in students' perceived definition of race from genetic, biological, geographical, and cultural factors to socio-political factors (P < 0.0001). Significant increases in almost all factors assessing student awareness of racism and confidence to advocate against racism were observed. Student-identified barriers to discussing racism included lack of education and lived experience, fear of starting conflict and offending others. All survey respondents would recommend this programme to peers and 69% (n = 32) engaged in further topical self-directed education.

CONCLUSION

This simple and reproducible programme improved awareness and confidence to advocate against racism in medicine and resulted in a change in opinion regarding race-based medical practice. These findings are in line with best practice towards addressing racial bias in medicine, decolonizing medical curricula and strengthening anti-racism teaching of future physicians.

Central serous chorioretinopathy secondary to intramuscular testosterone therapy

Summary

A patient treated with intramuscular testosterone replacement therapy for primary hypogonadism developed blurred vision shortly after receiving his testosterone injection. The symptom resolved over subsequent weeks and recurred after his next injection. A diagnosis of central serous chorioretinopathy (CSR) was confirmed following ophthalmology review. A decision was made to change the patient's testosterone regime from this 12-weekly intramuscular injection to a daily topical testosterone gel, given the possibility that peak blood levels of testosterone following intramuscular injection were causing his ocular complaint. His CSR did not recur after this change in treatment. CSR secondary to testosterone therapy is a rare finding but has been reported previously in the literature.

Learning Points

Blurred vision in patients treated with testosterone replacement therapy (TRT) should prompt an ophthalmology review. The potential for reduced risk of central serous chorioretinopathy (CSR) with daily transdermal testosterone remains a matter of conjecture. CSR is a rare potential side effect of TRT.

Utility of screening for silent myocardial ischaemia in diabetes with an annual electrocardiogram

BACKGROUND AND METHODS

Asymptomatic coronary artery disease (CAD) is common in people with diabetes mellitus, but there is a lack of consensus regarding appropriate screening for the condition. We performed a 12-lead electrocardiogram (ECG) on 312 consecutive participants with diabetes mellitus attending for routine annual outpatient review in order to determine the effectiveness of a yearly ECG in screening people with diabetes for asymptomatic CAD.

RESULTS

Three of 312 participants (0.96%, 95% CI 0.2%-2.78%) had a newly identified ECG abnormality. One person had newly discovered atrial fibrillation. Two people had abnormalities which prompted further investigation for asymptomatic CAD. One of these participants underwent percutaneous coronary intervention. Seventeen further participants had abnormalities on ECG which had been previously documented, the majority having been present since their diagnosis of diabetes.

CONCLUSION

A low positive yield of routine annual ECG in our study does not support its use as a screening tool for asymptomatic CAD in diabetes. Our findings support advice to perform an ECG at diagnosis of diabetes and to repeat only if a person develops relevant symptoms.

Impact of haemoglobin variants on the use of haemoglobin A1c for the diagnosis and monitoring of diabetes: a contextualised review

HbA1c is the established test for monitoring glycaemic control in diabetes, and intervention trials studying the impact of treatment on glycaemic control and risk of complications focus predominantly on this parameter in terms of evaluating the glycaemic outcomes. It is also the main parameter used when targets for control are being individualised, and more recently, it has been used for the diagnosis of type 2 diabetes. For laboratories performing this test and clinicians utilising it in their decision-making process, a thorough understanding of factors that can impact on the accuracy, and appropriate interpretation of the test is essential. The changing demographic in the Irish population over the last two decades has brought this issue sharply into focus. It is therefore timely to review the utility, performance and interpretation of the HbA1c test to highlight factors impacting on the results, specifically the impact of haemoglobin variants, and the impact of these factors on its utilisation in clinical practice.

An exploratory study of associations between sleep timing variability and cardiometabolic health in middle-aged adults with type 2 diabetes mellitus

Sleep is increasingly recognised as an important risk factor for metabolic disease, and as an important influence on severity in established metabolic disease. Recent evidence suggests that sleep timing variability (the day-to-day fluctuations of sleep timing) may be an important factor in metabolic diseases such as type 2 diabetes mellitus. In the current study, we explore the associations between measures of sleep timing variability and cardiometabolic measures in a group of healthy middle-aged adults with and without type 2 diabetes mellitus. Healthy controls (N = 27) and adults with well-controlled uncomplicated type 2 diabetes mellitus (N = 30) wore actiwatches for an average of 9 days for objective assessment of sleep timing parameters, and also underwent a detailed clinical assessment. We found greater self-reported social jetlag in the diabetes group, but no groupwise differences in measures of sleep timing variability. In the diabetes patients, HbA1c levels were inversely correlated with variability in the time of sleep onset and midsleep, and with sleep duration. HOMA-IR did not correlate with any sleep timing variability measure, nor were there associations between sleep timing variability and other metabolic biomarkers (cholesterol, LDL, HDL, triglycerides and uric acid). Systolic blood pressure was inversely correlated with actigraphically defined social jetlag in both the control and diabetes groups. The results of this study indicate associations between sleep timing variability and HbA1c, but the direction of these relationships is at variance with some other recent reports. Our results indicate a need for future hypothesis-testing studies to further explore the impact of sleep timing variance on metabolic health.

Exploring medical students' perceptions of the challenges and benefits of volunteering in the intensive care unit during the COVID-19 pandemic: a qualitative study

OBJECTIVES

In March 2020, the WHO declared SARS-CoV-2 a pandemic. Hospitals across the world faced staff, bed and supply shortages, with some European hospitals calling on medical students to fill the staffing gaps. This study aimed to document the impact of volunteering during the COVID-19 pandemic on students' professional development, resilience and future perceived career choices.

DESIGN

This is a retrospective, qualitative study of student reflections, using purposive sampling.The Royal College of Surgeons in Ireland (RCSI) University of Medicine and Health Sciences recruited 26 medical student volunteers to assist in pronation and supination of ventilated patients affected by SARS-CoV-2. These students were invited to complete an anonymous survey based on their experiences as volunteers. Thematic analysis was performed on these written reflections.

RESULTS

The results showed that volunteering during the COVID-19 pandemic developed key skills from RCSI's medical curriculum, significantly fostered medical students' resilience and guided their career choices. Major areas of development included communication, teamwork, compassion and altruism, which are not easily developed through the formal curriculum. A further area that was highlighted was the importance of evidence-based health in a pandemic. Finally, our respondents were early stage medical students with limited clinical exposure. Some found the experience difficult to cope with and therefore supports should be established for students volunteering in such a crisis.

CONCLUSION

These results suggest that clinical exposure is an important driver in developing students' resilience and that volunteering during a pandemic has multiple benefits to students' professional development and professional identity formation.

Testicular swelling leading to a diagnosis of adrenocortical carcinoma - co-incidence or causation?

SUMMARY

Adrenocortical carcinoma (ACC) is a rare malignancy with an incidence of 0.7-2.0 cases/million/year. A majority of patients present with steroid hormone excess or abdominal mass effects, and in 15% of patients ACC is discovered incidentally. We present a case of 30-year-old otherwise asymptomatic Caucasian male who presented with a testicular swelling. Subsequent imaging and investigations revealed disseminated sarcoidosis and an 11 cm adrenal lesion. An adrenalectomy was performed. Histological examination of the resected specimen confirmed an ACC and also demonstrated a thin rim of adrenal tissue containing non-caseating granulomas, consistent with adrenal sarcoid.

LEARNING POINTS

This case highlights an unusual presentation of two uncommon diseases. This case also highlights how separate and potentially unrelated disease processes may occur concomitantly and the importance, therefore, of keeping an open mind when dealing with unusual diagnostic findings. We also hypothesize a potential link between the ACC and sarcoidosis in our patient.

Barriers and facilitators to accessing insulin pump therapy by adults with type 1 diabetes mellitus: a qualitative study

AIMS

Uptake of continuous subcutaneous insulin infusion (CSII) by people with diabetes (PwD) in Ireland is low and exhibits regional variation. This study explores barriers and facilitators to accessing CSII by adults with Type 1 diabetes mellitus.

RESEARCH DESIGN AND METHODS

A qualitative study employing focus groups with adults with Type 1 diabetes mellitus (n = 26) and semi-structured interviews with health care professionals (HCP) and other key stakeholders (n = 21) was conducted. Reflexive thematic analysis was used to analyze data, using NVivo.

RESULTS

Four main themes comprising barriers to or facilitators of CSII uptake were identified. These included: (1) awareness of CSII and its benefits, (2) the structure of diabetes services, (3) the capacity of the diabetes service to deliver the CSII service, and (4) the impact of individuals' attitudes and personal characteristics-both PwD, and HCP. Each of these themes was associated with a number of categories, of which 18 were identified and explored. If the structure of the health-service is insufficient and capacity is poor (e.g., under-resourced clinics), CSII uptake appears to be impacted by individuals': interest, attitude, willingness and motivation, which may intensify the regional inequality in accessing CSII.

CONCLUSIONS

This study identified factors that contribute to gaps in the delivery of diabetes care that policy-makers may use to improve access to CSII for adult PwD.

Sociodemographic variables as predictors of adverse outcome in SARS-CoV-2 infection: an Irish hospital experience

Introduction

Our hospital found itself at the epicentre of the Irish COVID-19 pandemic. We describe the organisational challenges faced in managing the surge and identified risk factors for mortality and ICU admission among hospitalised SARS-CoV-2-infected patients.

Methods

All hospitalised SARS-CoV-2 patients diagnosed between March 13 and May 1, 2020, were included. Demographic, referral, deprivation, ethnicity and clinical data were recorded. Multivariable regression, including age-adjusted hazard ratios (HR (95% CI), was used to explore risk factors associated with adverse outcomes.

Results

Of 257 inpatients, 174 were discharged (68%) and 39 died (15%) in hospital. Two hundred three (79%) patients presented from the community, 34 (13%) from care homes and 20 (8%) were existing inpatients. Forty-five percent of community patients were of a non-Irish White or Black, Asian or minority ethnic (BAME) population, including 34 Roma (13%) compared to 3% of care home and 5% of existing inpatients, (p < 0.001). Twenty-two patients were healthcare workers (9%). Of 31 patients (12%) requiring ICU admission, 18 were discharged (58%) and 7 died (23%). Being overweight/obese HR (95% CI) 3.09 (1.32, 7.23), p = 0.009; a care home resident 2.68 (1.24, 5.6), p = 0.012; socioeconomically deprived 1.05 (1.01, 1.09), p = 0.012; and older 1.04 (1.01, 1.06), p = 0.002 were significantly associated with death. Non-Irish White or BAME were not significantly associated with death 1.31 (0.28, 6.22), p = 0.63 but were significantly associated with ICU admission 4.38 (1.38, 14.2), p = 0.014 as was being overweight/obese 2.37 (1.37, 6.83), p = 0.01.

Conclusion

The COVID-19 pandemic posed unprecedented organisational issues for our hospital resulting in the greatest surge in ICU capacity above baseline of any Irish hospital. Being overweight/obese, a care home resident, socioeconomically deprived and older were significantly associated with death, while ethnicity and being overweight/obese were significantly associated with ICU admission.

Availability of and access to continuous subcutaneous insulin infusion therapy for adults with type 1 diabetes in Ireland

AIMS

The uptake of continuous subcutaneous insulin infusion (CSII) is low in adults with type 1 diabetes mellitus (T1DM) in Ireland, compared to other countries where CSII is reimbursed. To explore the reasons for the low uptake, this study aims to investigate the availability of CSII in adult diabetes clinics in Ireland.

METHODS

A national survey of all adult diabetes clinics (public and private) in Ireland was conducted and completed anonymously by the lead physician/diabetes nurse specialist in each clinic. Descriptive statistics and comparisons between clinics offering different levels of care for CSII are presented.

RESULTS

Of 50 diabetes clinics invited, 47 (94%) participated in the study. Fifteen clinics (32%) offered no support for CSII, while 21 (45%) reported offering both training to commence CSII and ongoing support. Based on the survey findings, access to CSII was unavailable for 2426 (11%) of those with T1DM. The majority (n = 15,831, 71% of 22,321 T1DM population) received diabetes care from clinics offering CSII training, but only 2165 were using CSII (10% of T1DM population). Uptake of CSII was higher in clinics offering training than in those offering follow-up care for CSII only (12% vs. 5%, p < 0.001). Clinics offering all CSII services had more specialists (p = 0.005 for endocrinologists and p < 0.001 for dietitians). Reasons for not offering CSII services included staff shortages and heavy workload.

CONCLUSIONS

This study highlights the low uptake of CSII in Ireland and demonstrates that, even when reimbursed, other barriers to uptake of CSII can limit its use.

Low uptake of continuous subcutaneous insulin infusion therapy in people with type 1 diabetes in Ireland: a retrospective cross-sectional study

BACKGROUND

The uptake of continuous subcutaneous insulin infusion (CSII) therapy in those with type 1 diabetes varies internationally and is mainly determined by the national healthcare reimbursement systems. The aim of this study is to estimate national and regional uptake of CSII therapy in children, adolescents and adults with type 1 diabetes in Ireland.

METHODS

A retrospective cross-sectional study was conducted utilizing the national pharmacy claims database in 2016. Individuals using CSII were identified by dispensing of infusion sets. The uptake of CSII was calculated as the percentage of people with type 1 diabetes claiming CSII sets in 2016, both in children and adolescent (age < 18 years) and adult populations (≥ 18 years). Descriptive statistics including percentages with 95% confidence intervals (CIs) are presented, stratified by age-groups and geographical regions, and chi-square tests used for comparisons.

RESULTS

Of 20,081 people with type 1 diabetes, 2111 (10.5, 95% CI: 10.1-10.9%) were using CSII in 2016. Uptake was five-fold higher in children and adolescents at 34.7% (95% CI: 32.9-36.5%) than in adults at 6.8% (95% CI: 6.4-7.2%). Significant geographical heterogeneity in CSII uptake was found, from 12.6 to 53.7% in children and adolescents (p < 0.001), and 2 to 9.6% in adults (p < 0.001).

CONCLUSIONS

Uptake of CSII in people with type 1 diabetes is low in Ireland, particularly in those ≥18 years. Identification of barriers to uptake, particularly in this group, is required.

Prevalence and incidence of type 1 diabetes in Ireland: a retrospective cross-sectional study using a national pharmacy claims data from 2016

OBJECTIVES

The aim of this study is to estimate the prevalence and incidence of type 1 diabetes in the Irish population using a national pharmacy claims database in the absence of a national diabetes register.

DESIGN

National, population-based, retrospective, cross-sectional study.

SETTING

Community care with data available through the Health Service Executive Pharmacy Claims Reimbursement Scheme from 2011 to 2016.

PARTICIPANTS

Individuals with type 1 diabetes were identified by coprescription of insulin and glucometer test strips without any prolonged course (>12 months) of oral hypoglycaemic agents prior to commencing insulin. Those claiming prescriptions for long-acting insulin only, without any prandial insulin, were excluded from the analysis. Incidence was estimated based on the first claim for insulin in 2016, with no insulin use in the preceding 12 months.

MAIN OUTCOME MEASURES

Prevalence of type 1 diabetes in children (<18 years) and adults (≥18 years); incidence of type 1 diabetes in children (≤14 years) and adolescents and adults (>14 years).

RESULTS

There were 20 081 prevalent cases of type 1 diabetes in 2016. The crude prevalence was 0.42% (95% CI 0.42% to 0.43%). Most prevalent cases (n=17 053, 85%) were in adults with a prevalence of 0.48% (95% CI 0.47% to 0.48%). There were 1527 new cases of type 1 diabetes in 2016, giving an incidence rate of 32 per 100 000 population/year (95% CI 30.5 to 33.7). There was a significant positive linear trend for age, for prevalence (p<0.0001) and incidence (p=0.014). The prevalence and incidence were 1.2-fold and 1.3-fold higher in men than women, respectively. Significant variations in prevalence (p<0.0001) and incidence (p<0.001) between the different geographical regions were observed.

CONCLUSIONS

This study provides epidemiological estimates of type 1 diabetes across age groups in Ireland, with the majority of prevalent cases in adults. Establishing a national diabetes register is essential to enable updated epidemiological estimates of diabetes and for planning of services in Ireland.

Acute diabetic neuropathy following improved glycaemic control: a case series and review

SUMMARY

We present three cases of acute diabetic neuropathy and highlight a potentially underappreciated link between tightening of glycaemic control and acute neuropathies in patients with diabetes. Case 1: A 56-year-old male with poorly controlled type 2 diabetes (T2DM) was commenced on basal-bolus insulin. He presented 6 weeks later with a diffuse painful sensory neuropathy and postural hypotension. He was diagnosed with treatment-induced neuropathy (TIN, insulin neuritis) and obtained symptomatic relief from pregabalin. Case 2: A 67-year-old male with T2DM and chronic hyperglycaemia presented with left lower limb pain, weakness and weight loss shortly after achieving target glycaemia with oral anti-hyperglycaemics. Neurological examination and neuro-electrophysiological studies suggested diabetic lumbosacral radiculo-plexus neuropathy (DLPRN, diabetic amyotrophy). Pain and weakness resolved over time. Case 3: A 58-year-old male was admitted with blurred vision diplopia and complete ptosis of the right eye, with intact pupillary reflexes, shortly after intensification of glucose-lowering treatment with an SGLT2 inhibitor as adjunct to metformin. He was diagnosed with a pupil-sparing third nerve palsy secondary to diabetic mononeuritis which improved over time. While all three acute neuropathies have been previously well described, all are rare and require a high index of clinical suspicion as they are essentially a diagnosis of exclusion. Interestingly, all three of our cases are linked by the development of acute neuropathy following a significant improvement in glycaemic control. This phenomenon is well described in TIN, but not previously highlighted in other acute neuropathies.

LEARNING POINTS

A link between acute tightening of glycaemic control and acute neuropathies has not been well described in literature. Clinicians caring for patients with diabetes who develop otherwise unexplained neurologic symptoms following a tightening of glycaemic control should consider the possibility of an acute diabetic neuropathy. Early recognition of these neuropathies can obviate the need for detailed and expensive investigations and allow for early institution of appropriate pain-relieving medications.

Spurious HbA1c results in patients with diabetes treated with dapsone

SUMMARY

Measurement of glycated haemoglobin (HbA1c) has been utilised in assessing long-term control of blood glucose in patients with diabetes, as well as diagnosing diabetes and identifying patients at increased risk of developing diabetes in the future. HbA1c reflects the level of blood glucose to which the erythrocyte has been exposed during its lifespan, and there are a number of clinical situations affecting the erythrocyte life span in which HbA1c values may be spuriously high or low and therefore not reflective of the true level of glucose control. In the present case series, we describe the particulars of three patients with diabetes who had spuriously low HbA1c levels as a result of dapsone usage. Furthermore, we discuss the limitations of HbA1c testing and the mechanisms by which it may be affected by dapsone in particular.

LEARNING POINTS

Various conditions and medications can result in falsely low HbA1c. Dapsone can lead to falsely low HbA1c by inducing haemolysis and by forming methaemoglobin. Capillary glucose measurement, urine glucose measurements and fructosamine levels should be used as alternatives to HbA1c for monitoring glycaemic control if it was falsely low or high.

A review of the propriety of thyroid ultrasound referrals and their follow-up burden

PURPOSE

The overdiagnosis of thyroid nodules and indolent thyroid cancers represents an increasing burden on health services, with thyroid ultrasound (US) imaging often representing the initial entry point into the thyroid nodule diagnostic pathway. The aim of this study was to retrospectively review thyroid US referrals to a single Irish hospital to determine if the stated indications for imaging had been appropriate, to review the results of the scans, and to assess the follow-up required in each case.

METHODS

Patient demographics, scan indications, results, and outcomes were retrospectively reviewed for all patients undergoing thyroid ultrasound from 2012 to 2016. Data were analyzed using GraphPad Prism and expressed in mean ± standard deviation.

RESULTS

In total, 318 patients (mean age 53 ± 15 years, 85% female) had at least one ultrasound. Most US scans were performed for appropriate indications in order to follow up known thyroid nodular disease and/or malignancy (34.3%), to assess new thyroid goiters or discrete neck lumps (33.3%), and to follow up incidental findings from other imaging modalities (12.6%). However, scans were also requested (in the absence of any palpable goiter or mass) for choking/neck pain/swallowing complaints (12.3%), hypo/hyperthyroidism (6.6%), and miscellaneous reasons (0.6%) that were deemed either potentially or likely inappropriate. Of these scans, approximately half of the identified nodule(s) were deemed unlikely to be related to the stated symptoms, but which subsequently required follow-up imaging ± biopsy. No cases of malignancy were identified.

CONCLUSIONS

In our center, a significant percentage of thyroid US scans along with their subsequent follow-up were potentially avoidable.

Closing the gap: a transatlantic collaboration to foster quality improvement training in graduate entry medical students using applications of QI methodologies to medical education

The alarming prevalence of medical error and adverse events in the health system raises a call to action to ensure that doctors in training receive adequate training in quality improvement (QI). Training medical students in QI remains a challenge given time constraints, lack of clinical exposure, and already saturated curricula. In some instances, QI training may be delivered during clerkship through didactic, and in some instances, and experiential learning. Preclinical years of medical school remain focused on introducing students to scientific and clinical concepts, rarely do they learn about QI. The Program for Innovation in Scholarship and Medicine (PRISM) is a programme that introduces first-year medical students to the fundamentals of QI using their experience as a medical student as the context. PRISM is a condensed QI curriculum that is delivered through an international partnership, based on a previously piloted programme at a Canadian medical school. Following an introductory workshop, medical students work in teams to develop QI proposals (project charters) which detail how QI principles and tools can generate small-scale improvements within their educational programme. Project charters are assessed by a team of faculty and upper year students, who have previously participated. On completion of the programme, students demonstrated increased knowledge, skills, and attitudes towards QI. Programme participants were satisfied with the structure and expectations of PRISM and expressed a newfound interest in QI. Nearly all participants would recommend PRISM to another medical student. In conclusion, PRISM serves as a resourceful, efficient educational approach for preclerkship students that provides an introduction to the concepts of QI in order for early trainees to build on baseline knowledge and skills throughout their training.

A case of pembrolizumab-induced severe DKA and hypothyroidism in a patient with metastatic melanoma

Immune checkpoint inhibitors (ICIs) have revolutionised cancer therapy and improved outcomes for patients with advanced disease. Pembrolizumab, a monoclonal antibody that acts as a programmed cell death 1 (PD-1(PDCD1)) inhibitor, has been approved for the treatment of advanced melanoma and other solid tumours. Immune-related adverse events (irAEs) including endocrinopathies have been well described with this and other PD-1 inhibitors. While hypothyroidism and hyperthyroidism, and less commonly hypophysitis, are the most common endocrinopathies occurring in patients treated with pembrolizumab, the incidence of type 1 diabetes mellitus (T1DM) was low in clinical trials. We report a case of pembrolizumab-induced primary hypothyroidism and T1DM presenting with severe diabetic ketoacidosis (DKA). A 52-year-old male patient was treated with pembrolizumab for metastatic melanoma. He presented to the emergency department with a 1-day history of nausea and vomiting 2 weeks after his seventh dose of pembrolizumab, having complained of polyuria and polydipsia for 2 months before presentation. He had been diagnosed with thyroid peroxidase (TPO) antibody-negative hypothyroidism, requiring thyroxine replacement, shortly after his fifth dose. Testing revealed a severe DKA (pH: 6.99, glucose: 38.6 mmol/L, capillary ketones: 4.9 and anion gap: 34.7). He was treated in the intensive care unit as per the institutional protocol, and subsequently transitioned to subcutaneous basal-bolus insulin. After his diabetes and thyroid stabilised, pembrolizumab was recommenced to treat his advanced melanoma given his excellent response. This case highlights the importance of blood glucose monitoring as an integral part of cancer treatment protocols composed of pembrolizumab and other ICIs. Learning points: The incidence of T1DM with pembrolizumab treatment is being increasingly recognised and reported, and DKA is a common initial presentation. Physicians should counsel patients about this potential irAE and educate them about the symptoms of hyperglycaemia and DKA. The ESMO guidelines recommend regular monitoring of blood glucose in patients treated with ICIs, a recommendation needs to be incorporated into cancer treatment protocols for pembrolizumab and other ICIs in order to detect hyperglycaemia early and prevent DKA.

Clocks in the clinic: circadian rhythms in health and disease

Circadian rhythms are endogenously generated recurring patterns of around 24 hours with well-established roles in physiology and behaviour. These circadian clocks are important in both the aetiology and treatment of various psychiatric and metabolic diseases. To maintain physiological homeostasis and optimal functioning, living life synchronised to these clocks is desirable; modern society, however, promotes a '24/7' lifestyle where activity often occurs during the body's 'biological night', resulting in mistimed sleep and circadian misalignment. This circadian desynchrony can increase the risk of disease and can also influence treatment response. Clinicians should be aware of the influence that circadian desynchrony can have on health and disease, in order to potentially develop new therapeutic strategies and to incorporate chronotherapeutics into current treatment strategies to enhance their utility.

Medical student INtervention to promote effective nicotine dependence and tobacco HEalthcare (MIND-THE-GAP): single-centre feasibility randomised trial results

BACKGROUND

Although brief cessation advice from healthcare professionals increases quit rates, smokers typically do not get this advice during hospitalisation, possibly due to resource issues, lack of training and professionals' own attitudes to providing such counselling. Medical students are a potentially untapped resource who could deliver cessation counselling, while upskilling themselves and changing their own attitudes to delivering such advice in the future; however, no studies have investigated this. We aimed to determine if brief student-led counselling could enhance motivation to quit and smoking cessation behaviours among hospitalised patients.

METHODS

A mixed-methods, 2-arm pilot feasibility randomised controlled trial with qualitative process evaluation enrolled 67 hospitalised adult smokers, who were recruited and randomized to receive a brief medical student-delivered cessation intervention (n = 33) or usual care (n = 34); 61 medical students received standardised cessation training and 33 were randomly assigned to provide a brief in-hospital consultation and follow-up support by phone or in-person one week post-discharge. Telephone follow-up at 3- and 6-months assessed scores on the Motivation to Stop Smoking Scale (MTSS; primary outcome) and several other outcomes, including 7-day point prevalent abstinence, quit attempts, use of cessation medication, and ratings of student's knowledge and efficacy. Data were analysed as intention to treat (ITT) using penalised imputation, per protocol, and random effects repeated measures. Focus group interviews were conducted with students post-intervention to elicit their views on the training and intervention process.

RESULTS

Analyses for primary and most secondary outcomes favoured the intervention group, although results were not statistically significant. Point prevalence abstinence rates were significantly higher for the intervention group during follow-up for all analyses except 6-month ITT analysis. Fidelity was variable. Patients rated students as being "very" knowledgeable about quitting and "somewhat" helpful. Qualitative results showed students were glad to deliver the intervention; were critical of current cessation care; felt constrained by their inability to prescribe cessation medications and wanted to include cessation and other behavioural counselling in their normal history taking.

CONCLUSIONS

It appears feasible for medical students to be smoking cessation interventionists during their training, although their fidelity to the intervention requires further investigation. A definitive trial is needed to determine if medical students are effective cessation counsellors and if student-led intervention could be tailored for other health behaviours.

Effect of insulin glargine on recreational physical activity and TV viewing: Analysis of the randomised ORIGIN trial

AIMS

To quantify whether insulin therapy, and concomitant weight gain, affects recreational physical activity and TV viewing time using data from the Outcomes Reduction with an Initial Glargine Intervention (ORIGIN) trial.

METHODS

12,537 insulin-naïve individuals with dysglycaemia were randomised to receive either basal insulin glargine or standard care and followed for a median of 6.2years. Complete recreational physical activity and TV viewing time questionnaires across baseline, 2year follow-up and study end were available for 8954 participants. Differences between groups at follow-up were assessed by analysis of covariance.

RESULTS

At follow-up, there was no difference in physical activity or TV viewing time between those taking insulin glargine and those receiving standard care, despite body weight increasing by 1.66 (7.56) kg in the insulin glargine group and reducing by -0.65 (7.90) kg in the standard care group (P<0.001). The dose of insulin glargine was not associated with changes in physical activity.

CONCLUSIONS

Despite modest weight gain, insulin glargine did not adversely impact recreational physical activity levels within an international cohort with dysglyaemia. ORIGIN ClinicalTrials.gov number: NCT00069784.

Marked hyperandrogenicity in a 60-year-old woman

Markedly elevated androgen levels can lead to clinical virilization in females. Clinical features of virilization in a female patient, in association with biochemical hyperandrogenism, should prompt a search for an androgen-producing tumor, especially of ovarian or adrenal origin. We herein report the case of a 60-year-old woman of Pakistani origin who presented with the incidental finding of male pattern baldness and hirsutism. Her serum testosterone level was markedly elevated at 21 nmol/L (normal range: 0.4–1.7 nmol/L), while her DHEAS level was normal, indicating a likely ovarian source of her elevated testosterone. Subsequently, a CT abdomen-pelvis was performed, which revealed a bulky right ovary, confirmed on MRI of the pelvis as an enlarged right ovary, measuring 2.9 × 2.2 cm transaxially. A laparoscopic bilateral salpingo-oophorectomy was performed, and histopathological examination and immunohistochemistry confirmed the diagnosis of a Leydig cell tumor, a rare tumor accounting for 0.1% of ovarian tumors. Surgical resection led to normalization of testosterone levels.

A self-adherent, bullet-shaped microneedle patch for controlled transdermal delivery of insulin

Proteins are important biologic therapeutics used for the treatment of various diseases. However, owing to low bioavailability and poor skin permeability, transdermal delivery of protein therapeutics poses a significant challenge. Here, we present a new approach for transdermal protein delivery using bullet-shaped double-layered microneedle (MN) arrays with water-swellable tips. This design enabled the MNs to mechanically interlock with soft tissues by selective distal swelling after skin insertion. Additionally, prolonged release of loaded proteins by passive diffusion through the swollen tips was obtained. The bullet-shaped MNs provided an optimal geometry for mechanical interlocking, thereby achieving significant adhesion strength (~1.6Ncm^-2) with rat skin. By harnessing the MN's reversible swelling/deswelling property, insulin, a model protein drug, was loaded in the swellable tips using a mild drop/dry procedure. The insulin-loaded MN patch released 60% of insulin when immersed in saline over the course of 12h and approximately 70% of the released insulin appeared to have preserved structural integrity. An in vivo pilot study showed a prolonged release of insulin from swellable MN patches, leading to a gradual decrease in blood glucose levels. This self-adherent transdermal MN platform can be applied to a variety of protein drugs requiring sustained release kinetics.

The effects of insulin and liraglutide on osteoprotegerin and vascular calcification in vitro and in patients with type 2 diabetes

OBJECTIVE

Vascular calcification (VC) is inhibited by the glycoprotein osteoprotegerin (OPG). It is unclear whether treatments for type 2 diabetes are capable of promoting or inhibiting VC. The present study examined the effects of insulin and liraglutide on i) the production of OPG and ii) the emergence of VC, both in vitro in human aortic smooth muscle cells (HASMCs) and in vivo in type 2 diabetes.

DESIGN/METHODS

HASMCs were exposed to insulin glargine or liraglutide, after which OPG production, alkaline phosphatase (ALP) activity and levels of Runx2, ALP and bone sialoprotein (BSP) mRNA were measured. A prospective, nonrandomised human subject study was also conducted, in which OPG levels and coronary artery calcification (CAC) were measured in a type 2 diabetes population before and 16 months after the commencement of either insulin or liraglutide treatment and in a control group that took oral hypoglycemics only.

RESULTS

Exposure to insulin glargine, but not liraglutide, was associated with significantly decreased OPG production (11 913±1409 pg/10(4) cells vs 282±13 pg/10(4) cells, control vs 10 nmol/l insulin, P<0.0001), increased ALP activity (0.82±0.06 IU/10(4) cells vs 2.40±0.16 IU/10(4) cells, control vs 10 nmol/l insulin, P<0.0001) and increased osteogenic gene expression by HASMCs. In the clinical study (n=101), insulin treatment was associated with a significant reduction in OPG levels and, despite not achieving full statistical significance, a trend towards increased CAC in patients.

CONCLUSION

Exogenous insulin down-regulated OPG in vitro and in vivo and promoted VC in vitro. Although neither insulin nor liraglutide significantly affected CAC in the present pilot study, these data support the establishment of randomised trials to investigate medications and VC in diabetes.

Insulin degludec improves long-term glycaemic control similarly to insulin glargine but with fewer hypoglycaemic episodes in patients with advanced type 2 diabetes on basal-bolus insulin therapy

The aim of the present study was to compare the long-term safety and efficacy of insulin degludec with those of insulin glargine in patients with advanced type 2 diabetes (T2D) over 78 weeks (the 52-week main trial and a 26-week extension). Patients were randomized to once-daily insulin degludec or insulin glargine, with mealtime insulin aspart ± metformin ± pioglitazone, and titrated to pre-breakfast plasma glucose values of 3.9-4.9 mmol/l (70-88 mg/dl). After 78 weeks, the overall rate of hypoglycaemia was 24% lower (p = 0.011) and the rate of nocturnal hypoglycaemia was 31% lower (p = 0.016) with insulin degludec in the extension trial set, while both groups of patients achieved similar glycaemic control. Rates of adverse events and total insulin doses were similar for both groups in the safety analysis set. During 18 months of treatment, insulin degludec + mealtime insulin aspart ± oral antidiabetic drugs in patients with T2D improves glycaemic control similarly, but confers lower risks of overall and nocturnal hypoglycaemia than with insulin glargine treatment.

Comparison of performance in a four year graduate entry medical programme and a traditional five/six year programme

BACKGROUND

In 2006 the Royal College of Surgeons in Ireland, (RCSI), introduced the first four year Graduate Entry Programme (GEP) in medicine in Ireland in line with national policy to broaden access to medical education. One concern considered at the time, was whether the GEP students could be trained to the same standard as their undergraduate Direct Entry Programme (DEP, five/six year duration) counterparts in the shorter time frame. Since students from both cohorts undertake the same examinations in the final two years, it is possible to directly compare GEP vs DEP outcomes. The primary aim of the current study was to analyse the comparative performance of GEP and DEP students undergoing these examinations between 2008 and 2013.

METHODS

Scores from five assessments performed during the final two years were transformed to z scores for each student and 4 scores for the penultimate year were summed to create a unit weighted composite score. The resultant scores for each of the two years were used to assess the comparative performance of GEP vs DEP cohorts and to perform sub-cohort analyses of GEP outcomes.

RESULTS

In all cohorts/years examined, evidence demonstrated significantly better assessment outcomes for the GEP group for the final two years' examinations as compared with the DEP group. In all but one cohort examined, this advantage was retained when nationality factors were excluded. Further analyses showed no difference in outcomes between GEP students having science vs. non-science backgrounds and/or between those from EU vs non-EU backgrounds. Finally, data suggested weak correlations between total composite scores and entry scores in American (r = 0.15) and Australian (r = 0.08) medical school admissions tests.

CONCLUSIONS

We have shown for the first time in Ireland, that graduate-entry students perform at least as well, or even better, than a corresponding undergraduate-entry group. Moreover, having a scientific background on entry to the GEP confers no advantage in final assessments. These data provide evidence of the viability of the graduate entry route into medical education in Ireland.

Increased Risk of Severe Hypoglycemic Events with Increasing Frequency of Non-severe Hypoglycemic Events in Patients with Type 1 and Type 2 Diabetes

INTRODUCTION

Severe hypoglycemic events (SHEs) are associated with significant morbidity, mortality and costs. However, the more common non-severe hypoglycemic events (NSHEs) are less well explored. We investigated the association between reported frequency of NSHEs and SHEs among patients with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) in the PREDICTIVE study.

METHODS

PREDICTIVE was a global, prospective, observational study. Patients with T1DM (n = 7,420) or T2DM (n = 12,981), starting treatment with insulin detemir, reported the number of NSHEs and SHEs experienced during the 4 weeks prior to baseline and follow-up visits (mean 14.4 weeks). Logistic regression was used to determine the odds ratio (OR) of experiencing ≥1 SHE, in patients having 1-4 or ≥5 NSHEs, versus those having 0 NSHEs, while controlling for baseline covariates.

RESULTS

Hypoglycemia rates were lower at follow-up than baseline. At baseline 59.2% (T1DM) and 18.8% (T2DM) reported any hypoglycemia and at follow-up 39.5% (T1DM) and 8.6% (T2DM). There was a significant (P < 0.0001) increase in the odds of ≥1 SHEs with increasing frequency of NSHEs in T1DM and T2DM, for both crude and adjusted estimates. At baseline, in T1DM, ORs for ≥1 SHE were 1.92 and 2.13 for 1-4 and ≥5 NSHEs, respectively; the corresponding ORs in T2DM were 10.83 and 15.36, respectively. At follow-up, the ORs for ≥1 SHE were 2.01 and 3.20 (T1DM) and 18.99 and 24.29 (T2DM) for 1-4 and ≥5 NSHEs, respectively.

CONCLUSION

A statistically significant association between NSHE and SHE frequency was found in T1DM and T2DM. These data provide a clear rationale for the reduction of hypoglycemic events, regardless of severity, while striving for optimal glycemic control.

Dealing with the devil: weight loss concerns in young adult women with type 1 diabetes

AIMS AND OBJECTIVES

To examine the weight loss concerns of young adults with type 1 diabetes.

BACKGROUND

Eating disorders are prevalent in young women with type 1 diabetes.

DESIGN

Qualitative.

METHODS

Interviews with 35 young adults (23-30 years of age) with type 1 diabetes and 13 healthcare professionals.

RESULTS

Most female interviewees were concerned about the difficulties of losing weight when having diabetes. Six female interviewees developed severe eating disturbances when they were younger. These women initially regarded their disturbed eating behaviour positively and engaged in weight loss activities intermittently. However, over time, they lost control of their behaviour, and it came to dominate their lives. Family conflict often intensified disordered eating behaviours. Eventually all of these women managed to transition away from their behaviour, although this process took, for some of them, several years. Several of them (now in their early to late twenties), however, continued to struggle with weight loss impulses. Healthcare professionals felt that eating- and weight-related issues often went undiagnosed and undocumented in young adult women with type 1 diabetes.

CONCLUSION

Many young women with type 1 diabetes are worried about their weight, but will not engage in risky weight loss activities because of concerns about their health. A minority of young adult women will develop more severe eating-related disturbances. These eating disturbances may last a significant amount of time before clinicians become aware of them. These women may also experience disordered weight loss impulses for sometime after clinical interventions.

RELEVANCE TO CLINICAL PRACTICE

Clinicians should screen young adult women with type 1 diabetes for eating disorders and monitor young adult women who have developed eating disorders over the longer term. There may be a need to provide asymptomatic young women with diabetes with information about the potential risks of insulin omission.

Effects of prostaglandin F(2α) on adipocyte biology relevant to graves' orbitopathy

BACKGROUND

In Graves' orbitopathy (GO), increased proliferation, excess adipogenesis, and hyaluronan overproduction produce GO exophthalmos. Enophthalmos occurs in some glaucoma patients treated with Bimatoprost (prostaglandin F2α, PGF2α) eye drops. We hypothesized that enophthalmos is secondary to reductions in orbital tissue proliferation, adipogenesis, and/or increased lipolysis. We aimed to determine which of these is affected by PGF2α by using the 3T3-L1 murine preadipocyte cell line and primary human orbital fibroblasts (OFs) from GO patients (n=5) and non-GO (n=5).

METHODS

3T3-L1 cells and orbital OFs were cultured alone or with PGF2α (all experiments used 10(-8) to 10(-6) M) and counted on days 1/2/3 or 5, respectively; cell cycle analysis (flow cytometry) was applied. Adipogenesis (in the presence/absence of PGF2α) was evaluated (day 7 or 15 for 3T3-L1 and primary cells, respectively) morphologically by Oil Red O staining and quantitative polymerase chain reaction measurement of adipogenesis markers (glycerol-3-phosphate dehydrogenase and lipoprotein lipase, respectively). For lipolysis, in vitro-differentiated 3T3-L1 or mature orbital adipocytes were incubated with norepinephrine and PGF2α and free glycerol was assayed. Appropriate statistical tests were applied.

RESULTS

The population doubling time of 3T3-L1 was 27.3±1.4 hours-significantly increased by dimethyl sulfoxide 0.02% to 44.6±4.8 hours (p=0.007) and further significantly increased (p=0.049 compared with dimethyl sulfoxide) by 10(-8) M PGF2α to 93.6±19.0 hours, indicating reduced proliferation, which was caused by prolongation of G2/M. GO OFs proliferated significantly more rapidly than non-GO (population doubling time 5.36±0.34 or 6.63±0.35 days, respectively, p=0.035), but the proliferation of both was significantly reduced (dose dependent from 10(-8) M) by PGF2α, again with prolongation of G2/M. Adipogenesis in 3T3-L1 cells was minimally affected by PGF2α when assessed morphologically, but the drug significantly reduced transcripts of the glycerol-3-phosphate dehydrogenase differentiation marker. GO OFs displayed significantly higher adipogenic potential than non-GO, but in both populations, adipogenesis, evaluated by all 3 methods, was significantly reduced (dose dependent from 10(-8) M) by PGF2α. There was no effect of PGF2α on basal or norepinephrine-induced lipolysis, in 3T3-L1 or human OFs, either GO or non-GO.

CONCLUSIONS

The results demonstrate that PGF2α significantly reduces proliferation and adipogenesis and that human OFs are more sensitive to its effects than 3T3-L1. Consequently, PGF2α could be effective in the treatment of GO.

Considering quality of care for young adults with diabetes in Ireland

BACKGROUND

Research on the quality of diabetes care provided to young adults with Type 1 diabetes is lacking. This study investigates perceptions of quality of care for young adults with Type 1 diabetes (23-30 years old) living in the Republic of Ireland.

METHODS

Thirty-five young adults with Type 1 diabetes (twenty-nine women, six men) and thirteen healthcare professionals (ten diabetes nurse specialists, three consultant Endocrinologists) were recruited. All study participants completed semi-structured interviews that explored their perspectives on the quality of diabetes services in Ireland. Interviews were analyzed using standard qualitative thematic analysis techniques.

RESULTS

Most interviewees identified problems with Irish diabetes services for young adults. Healthcare services were often characterised by long waiting times, inadequate continuity of care, overreliance on junior doctors and inadequate professional-patient interaction times. Many rural and non-specialist services lacked funding for diabetes education programmes, diabetes nurse specialists, insulin pumps or for psychological support, though these services are important components of quality Type 1 diabetes healthcare. Allied health services such as psychology, podiatry and dietician services appeared to be underfunded in many parts of the country. While Irish diabetes services lacked funding prior to the recession, the economic decline in Ireland, and the subsequent austerity imposed on the Irish health service as a result of that decline, appears to have additional negative consequences. Despite these difficulties, a number of specialist healthcare services for young adults with diabetes seemed to be providing excellent quality of care. Although young adults and professionals identified many of the same problems with Irish diabetes services, professionals appeared to be more critical of diabetes services than young adults. Young adults generally expressed high levels of satisfaction with services, even where they noted that aspects of those services were sub-optimal.

CONCLUSION

Good quality care appears to be unequally distributed throughout Ireland. National austerity measures appear to be negatively impacting health services for young adults with diabetes. There is a need for more Endocrinologist and diabetes nurse specialist posts to be funded in Ireland, as well as allied health professional posts.

A silent myocardial infarction in the diabetes outpatient clinic: case report and review of the literature

Silent myocardial ischaemia (SMI), defined as objective evidence of myocardial ischaemia in the absence of symptoms, has important clinical implications for the patient with coronary artery disease. We present a dramatic case of SMI in a diabetes patient who attended annual review clinic with ST elevation myocardial infarction. His troponin was normal on admission but raised to 10.7 ng/ml (normal <0.5) when repeated the next day. His angiogram showed diffused coronary artery disease. We here discuss the implications of silent ischaemia for the patient and for the physician caring for patients with diabetes.

What's distressing about having type 1 diabetes? A qualitative study of young adults' perspectives

BACKGROUND

Diabetes distress is a general term that refers to the emotional burdens, anxieties, frustrations, stressors and worries that stem from managing a severe, complex condition like Type 1 diabetes. To date there has been limited research on diabetes-related distress in younger people with Type 1 diabetes. This qualitative study aimed to identify causes of diabetes distress in a sample of young adults with Type 1 diabetes.

METHODS

Semi-structured interviews with 35 individuals with Type 1 diabetes (23-30 years of age).

RESULTS

This study found diabetes related-distress to be common in a sample of young adults with Type 1 diabetes in the second phase of young adulthood (23-30 years of age). Diabetes distress was triggered by multiple factors, the most common of which were: self-consciousness/stigma, day-to-day diabetes management difficulties, having to fight the healthcare system, concerns about the future and apprehension about pregnancy. A number of factors appeared to moderate distress in this group, including having opportunities to talk to healthcare professionals, attending diabetes education programmes and joining peer support groups. Young adults felt that having opportunities to talk to healthcare professionals about diabetes distress should be a component of standard diabetes care.

CONCLUSIONS

Some aspects of living with diabetes frequently distress young adults with Type 1 diabetes who are in their twenties. Clinicians should facilitate young adults' attendance at diabetes education programmes, provide them with opportunities to talk about their diabetes-related frustrations and difficulties and, where possible, assist in the development of peer-support networks for young adults with diabetes.

Barriers to exercise in obese patients with type 2 diabetes

BACKGROUND

Although regular exercise is a critical component of the management of type 2 diabetes, many patients do not meet their exercise targets. Lack of exercise is associated with obesity and adverse cardiovascular outcomes.

AIM

We aimed to assess exercise habits in obese Irish patients with type 2 diabetes to determine if patients are adhering to exercise guidelines and to identify perceived barriers to exercise in this group.

DESIGN

A cross-sectional study of obese patients with type 2 diabetes attending routine outpatient diabetes clinics at our institution, a public teaching hospital located on the outskirts of Dublin City.

METHODS

A total of 145 obese patients with type 2 diabetes were administered a questionnaire to evaluate exercise habits and perceived barriers to exercise. Anthropometric details were measured.

RESULTS

About 47.6% (n = 69) of patients exercised for <150 minutes per week (40% of males, 62% of females; P = 0.019) and these patients had a higher body mass index than those meeting targets (35 vs. 33.5 kg/m(2); P = 0.02). Perceived barriers to exercise were varied, with lack of time and physical discomfort being the most common. Reported barriers to exercise varied with age, gender and marital status.

CONCLUSION

This study highlights the challenges facing clinicians in improving exercise levels in patients, and the need to identify the specific barriers to exercise in the individual to improve health outcomes.

Once-weekly exenatide versus once- or twice-daily insulin detemir: randomized, open-label, clinical trial of efficacy and safety in patients with type 2 diabetes treated with metformin alone or in combination with sulfonylureas

OBJECTIVE

This multicenter, open-label, parallel-arm study compared the efficacy and safety of exenatide once weekly (EQW) with titrated insulin detemir in patients with type 2 diabetes inadequately controlled with metformin (with or without sulfonylureas).

RESEARCH DESIGN AND METHODS

Patients were randomized to EQW (2 mg) or detemir (once or twice daily, titrated to achieve fasting plasma glucose ≤5.5 mmol/L) for 26 weeks. The primary outcome was proportion of patients achieving A1C ≤7.0% and weight loss ≥1.0 kg at end point, analyzed by means of logistic regression. Secondary outcomes included measures of glycemic control, cardiovascular risk factors, and safety and tolerability.

RESULTS

Of 216 patients (intent-to-treat population), 111 received EQW and 105 received detemir. Overall, 44.1% (95% CI, 34.7-53.9) of EQW-treated patients compared with 11.4% (6.0-19.1) of detemir-treated patients achieved the primary outcome (P < 0.0001). Treatment with EQW resulted in significantly greater reductions than detemir in A1C (least-square mean ± SE, -1.30 ± 0.08% vs. -0.88 ± 0.08%; P < 0.0001) and weight (-2.7 ± 0.3 kg vs. +0.8 ± 0.4 kg; P < 0.0001). Gastrointestinal-related and injection site-related adverse events occurred more frequently with EQW than with detemir. There was no major hypoglycemia in either group. Five (6%) patients in the EQW group and six (7%) patients in the detemir group experienced minor hypoglycemia; only one event occurred without concomitant sulfonylureas (detemir group).

CONCLUSIONS

Treatment with EQW resulted in a significantly greater proportion of patients achieving target A1C and weight loss than treatment with detemir, with a low risk of hypoglycemia. These results suggest that EQW is a viable alternative to insulin detemir treatment in patients with type 2 diabetes with inadequate glycemic control using oral antidiabetes drugs.

Endothelial progenitor cells in mothers of low-birthweight infants: a link between defective placental vascularization and increased cardiovascular risk?

CONTEXT

Offspring birthweight is inversely associated with future maternal cardiovascular mortality, a relationship that has yet to be fully elucidated. Endothelial progenitor cells (EPCs) are thought to play a key role in vasculogenesis, and EPC numbers reflect cardiovascular risk.

OBJECTIVE

Our objective was to ascertain whether EPC number or function was reduced in mothers of low-birthweight infants.

DESIGN AND SETTING

This was a prospective cohort study in a general antenatal department of a university maternity hospital.

PARTICIPANTS

Twenty-three mothers of small for gestational age (SGA) infants (birthweight < 10th centile) and 23 mothers of appropriate for gestational age (AGA) infants (birthweight ≥ 10th centile) were recruited.

MAIN OUTCOME MEASURES

Maternal EPC number and function, conventional cardiovascular risk markers, and cord blood adiponectin were measured.

RESULTS

Median EPC count was lower (294 vs. 367, P = 0.005) and EPC migration was reduced (0.91 vs. 1.59, P < 0.001) in SGA compared with AGA infants, with no difference in EPC adhesion (0.221 vs. 0.284 fluorescence units, P = 0.257). Maternal triglyceride levels were higher in SGA than AGA infants (0.98 vs. 0.78 mmol/liter, P = 0.006), but there was no difference in cholesterol, glucose, insulin, glycosylated hemoglobin, adiponectin, or blood pressure. There was a moderate monotone (increasing) relationship between birthweight and umbilical cord blood adiponectin (r = 0.475, P = 0.005).

CONCLUSION

Giving birth to an SGA infant was associated with lower maternal EPC number and reduced migratory function. Cord blood adiponectin was significantly correlated with birthweight.

Association between Sleep Disruption and Levels of Lipids in Caucasians with Type 2 Diabetes

Aim. To investigate the association between sleep quality and duration with lipid and glycaemic control in Caucasian subjects with type 2 diabetes. Methods. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) in 114 type 2 diabetes (T2DM) subjects. Comparisons were made between subjects with different sleep quality and sleep duration. Hierarchical multiple regression analyses were used to determine contributors to metabolic parameters. Results. Subjects with poor sleep quality (PQ; PSQI ≥ 6) had higher systolic blood pressure, glycated haemoglobin, urine albumin : creatinine ratio (UAC), total cholesterol (TC), and triglycerides (TG) (P < 0.05 for all) compared to those with good sleep quality (GQ; PSQI ≤ 5). Long sleep duration (LSD) subjects had higher TC and short sleep duration (SSD) subjects had higher TG compared to those with medium sleep duration. Sleep duration and PSQI score were independent predictors of TC and low-density lipoprotein cholesterol (LDL), contributing to 14.0% and 6.1% of the total variance, respectively. Conclusions. In this Caucasian T2DM population, PQ is associated with adverse cardiovascular risk markers, and long and short sleep disruptions have an independent negative impact on lipids. Sleep assessment should be included as part of a diabetes clinic review.

Metastatic pituitary carcinoma in a patient with acromegaly: a case report

Introduction

Asymptomatic pituitary abnormalities occur in about 10% of cranial magnetic resonance imaging scans, but metastatic carcinoma of the pituitary gland is rare: 133 cases have been reported. Two thirds secreted either prolactin or adrenocorticotropic hormone, and another 24% were non-secreting.

Case presentation

A 42-year-old Caucasian man lived for 30 years after the diagnosis of a pituitary tumor whose clinical and biochemical features were those of acromegaly and hypogonadism. Radiotherapy, totaling 7300 rad, was administered to the sella over two courses. Growth hormone levels normalized, but he developed both thyroid and adrenal insufficiency, and replacement therapy was commenced. Fourteen years later, growth hormone levels again became elevated, and bromocriptine was commenced but led to side effects that could not be tolerated. An attempted surgical intervention failed, and octreotide and pergolide were used in succession. Twenty-seven years after the diagnosis, a mass from an excisional biopsy of below the angle of the mandible proved to be metastatic pituitary carcinoma. Immunohistochemical staining was positive for synaptophysin, growth hormone, and prolactin. One year later, an octreotide scan showed uptake at the sella, neck, and spleen. Our patient declined further active oncology treatment.

Conclusions

Metastatic pituitary carcinoma associated with acromegaly is particularly rare. To the best of our knowledge, this is the eighth such case and is the first report of growth hormone and prolactin present in the metastatic mass.

Insulin degludec, an ultra-longacting basal insulin, versus insulin glargine in basal-bolus treatment with mealtime insulin aspart in type 2 diabetes (BEGIN Basal-Bolus Type 2): a phase 3, randomised, open-label, treat-to-target non-inferiority trial

BACKGROUND

Basal insulin therapy does not stop loss of β-cell function, which is the hallmark of type 2 diabetes mellitus, and thus diabetes control inevitably deteriorates. Insulin degludec is a new, ultra-longacting basal insulin. We aimed to assess efficacy and safety of insulin degludec compared with insulin glargine in patients with type 2 diabetes mellitus.

METHODS

In this 52 week, phase 3, open-label, treat-to-target, non-inferiority trial, undertaken at 123 sites in 12 countries, we enrolled adults (aged ≥18 years) with type 2 diabetes mellitus and a glycated haemoglobin (HbA(1c)) of 7·0-10·0% after 3 months or more of any insulin regimen (with or without oral antidiabetic drugs). We randomly allocated eligible participants in a 3:1 ratio to receive once-daily subcutaneous insulin degludec or glargine, stratified by previous insulin regimen, via a central interactive response system. Basal insulin was titrated to a target plasma glucose concentration of 3·9-<5·0 mmol/L self-measured before breakfast. The primary outcome was non-inferiority of degludec to glargine measured by change in HbA(1c) from baseline to week 52 (non-inferiority limit of 0·4%) by ANOVA in the full analysis set. We assessed rates of hypoglycaemia in all treated patients. This study is registered with ClinicalTrials.gov, number NCT00972283.

FINDINGS

744 (99%) of 755 participants randomly allocated degludec and 248 (99%) of 251 allocated glargine were included in the full analysis set (mean age 58·9 years [SD 9·3], diabetes duration 13·5 years [7·3], HbA(1c) 8·3% [0·8], and fasting plasma glucose 9·2 mmol/L [3·1]); 618 (82%) and 211 (84%) participants completed the trial. After 1 year, HbA(1c) decreased by 1·1% in the degludec group and 1·2% in the glargine group (estimated treatment difference [degludec-glargine] 0·08%, 95% CI -0·05 to 0·21), confirming non-inferiority. Rates of overall confirmed hypoglycaemia (plasma glucose <3·1 mmol/L or severe episodes requiring assistance) were lower with degludec than glargine (11·1 vs 13·6 episodes per patient-year of exposure; estimated rate ratio 0·82, 95% CI 0·69 to 0·99; p=0·0359), as were rates of nocturnal confirmed hypoglycaemia (1·4 vs 1·8 episodes per patient-year of exposure; 0·75, 0·58 to 0·99; p=0·0399). Rates of severe hypoglycaemia seemed similar (0·06 vs 0·05 episodes per patient-year of exposure for degludec and glargine) but were too low for assessment of differences. Rates of other adverse events did not differ between groups.

INTERPRETATION

A policy of suboptimum diabetes control to reduce the risk of hypoglycaemia and its consequences in advanced type 2 diabetes mellitus might be unwarranted with newer basal insulins such as degludec, which are associated with lower risks of hypoglycaemia than insulin glargine.

Executive function and diabetes mellitus--a stone left unturned?

Diabetes mellitus (DM) is a chronic medical condition that is dependent upon patients self-caring and managing their condition to achieve optimal control. Adherence to medical therapy, making decisions related to lifestyle changes, and self-treating hypoglycaemia for example, require planning and organisational skills that are under the control of a specific domain of cognitive function known as executive function. Executive function has been shown by functional imaging studies such as magnetic resonance imaging to be under the influence of the frontal and prefrontal cortical system. It is now recognised that even in subjects with apparently normal cognition, DM may be associated with impaired executive function (IEF). The exact cause of IEF in DM is still not fully understood. However cerebral microvascular disease and chronic dysglycaemia have been postulated as possible factors contributing to functional neuronal dysfunction leading to IEF. IEF may adversely affect patients' abilities to self-manage their diabetes care, potentially cause worsening glycaemic control and difficulty managing risk factors. Several bedside assessment tools to screen for IEF are currently available and have been shown to correlate with functional status. However, more studies are needed to validate these tests against diabetes self-care assessment tools. Until then, clinicians and healthcare workers managing patients with DM should be aware of the potential for IEF in their patients as specific behaviour and education intervention may be needed to help manage patients with diabetes and IEF.

A case of spontaneous hypoglycaemia and impaired glucose tolerance in the same patient

We present a rare case of an insulin-like growth factor-2 (IGF-2)-secreting tumour of the thorax. This patient demonstrated the combination of fasting hypoglycaemia and impaired glucose tolerance on oral glucose tolerance testing, which has not been previously described in this condition. A review of the literature of IGF-2-secreting intrathoracic tumours is presented here.

Interns as teachers of medical students: a pilot programme

BACKGROUND

In recent years, rising numbers of medical students and an increasingly demanding clinical workload has put pressures on the educational systems for medical students in the hospital. Bedside teaching remains central to education, but tutorial delivery by registrars, tutors and consultants has proven to be increasingly difficult with the greater numbers of students now in the undergraduate system.

AIMS

We have performed a pilot study to determine the feasibility of developing a Junior Tutor Programme, to assist in the delivery of tutorials to undergraduate medical students.

METHODS

This was designed and delivered by interns under the supervision of the academic staff in the Departments of Medicine and Surgery in Connolly Hospital. The programme was evaluated by a questionnaire filled in by the students anonymously.

RESULTS

A supervised programme of tutorials delivered by interns is a potentially useful way to ensure delivery of clinical teaching to undergraduate medical students.

Utilization of Frontal Assessment Battery and Executive Interview 25 in assessing for dysexecutive syndrome and its association with diabetes self-care in elderly patients with type 2 diabetes mellitus

AIMS

Executive function (EF) comprises a set of cognitive skills that controls the execution of complex activities. In the context of diabetes, this may include patients' self-monitoring and daily management of their condition. We compared two different measures of EF in a population of elderly patients with type 2 diabetes mellitus (T2DM) and studied its relationship with diabetes self-care.

METHODS

Fifty patients (34 males) had EF assessed using Frontal Assessment Battery (FAB) and Executive Interview 25 (EXIT25). Diabetes self-care was assessed using the Summary of Diabetes Self-Care Activities (SDSCA) scale. Haemoglobin A1c (HbA1c), lipid levels, blood pressure and diabetes duration were recorded.

RESULTS

The mean age of the patients was 67.0+/-7.5 years and mean duration of diabetes was 8.1+/-6.4 years. Mean HbA1c was 7.0+/-1.2%, and mean fasting plasma glucose, cholesterol and LDL-C were 7.0+/-1.7mM, 4.0+/-0.9mM and 2.1+/-0.7mM respectively. Mean EXIT25 score was 9.5+/-4.6 in the range of normal EF (14% had EXIT25 score>15, indicating impaired EF). Mean FAB score was 13.7+/-3.3 (48% having scores<15, indicating impaired EF), suggesting a degree of dysexecutive syndrome involving frontal lobe functions. EXIT25 score was inversely correlated with SDSCA (r=-0.3, p<0.05) but no significant correlation between FAB and SDSCA or HbA1c, diabetes duration, lipid levels and blood pressure with EXIT25, FAB or SDCSA was found.

CONCLUSION

A substantial proportion of elderly patients with T2DM may have dysexecutive syndrome and impairment in EF may impact on self-care in this group.
