Medication errors at hospital admission and discharge in Type 1 and 2 diabetes

International audienceAIMS: To assess the prevalence and characteristics of medication errors at hospital admission and discharge in people with Type 1 and Type 2 diabetes, and identify potential risk factors for these errors. METHODS: This prospective observational study included all people with Type 1 (n~=~163) and Type 2 diabetes (n~=~508) admitted to the Diabetology-Department of the University Hospital of Montpellier, France, between 2013 and 2015. Pharmacists conducted medication reconciliation within 24~h of admission and at hospital discharge. Medication history collected from different sources (patient/family interviews, prescriptions/medical records, contact with community pharmacies/general practitioners/nurses) was compared with admission and discharge prescriptions to detect unintentional discrepancies in medication indicating involuntary medication changes. Medication errors were defined as unintentional medication discrepancies corrected by physicians. Risk factors for medication errors and serious errors (i.e. errors that may cause harm) were assessed using logistic regression. RESULTS: A total of 322 medication errors were identified and were mainly omissions. Prevalence of medication errors in Type 1 and Type 2 diabetes was 21.5% and 22.2% respectively at admission, and 9.0% and 12.2% at discharge. After adjusting for age and number of treatments, people with Type 1 diabetes had nearly a twofold higher odds of having medication errors (odds ratio (OR) 1.72, 95% confidence interval (CI) 1.02-2.94) and serious errors (OR 2.17, 95% CI 1.02-4.76) at admission compared with those with Type 2 diabetes. CONCLUSIONS: Medication reconciliation identified medication errors in one third of individuals. Clinical pharmacists should focus on poly-medicated individuals, but also on other high-risk people, for example, those with Type 1 diabetes

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

Placebo controlled pilot trial to study the remyelinating potential of intravenous immunoglobulins in multiple sclerosis

Currently there is no treatment available to improve a stable deficit in multiple sclerosis. It was shown in animal models that intravenous immunoglobulins (IVIg) can enhance central nervous remyelination, and the first open trials were promising. We therefore conducted a double blind, placebo controlled pilot study to evaluate the effect of IVIg treatment in patients with multiple sclerosis with a stable clinical deficit. The primary outcome parameter was the change in central motor conduction time as an indirect measure of central myelination. Secondary outcome parameters were neurological examinations including the expanded disability status scale (EDSS), neurological rating scale (NRS), and manual muscle testing (MMT). Ten patients were treated first with placebo and then with IVIg (0.4 g/kg body weight on 5 consecutive days), the two treatments being separated by an interval of 6 weeks. There was no difference in the central motor conduction times measured before and 6 weeks after each treatment. Clinically there was a small improvement after IVIg treatment, but there was no significant difference when compared with placebo. In conclusion, our data do not support a role for IVIg in the remyelination of stable multiple sclerosis lesions as measured by central conduction time. The importance of the small clinical benefit is currently not clear.


Immunoglobulins for intravenous use inhibit TNF alpha cytotoxicity in vitro.

Intravenous immunoglobulins (IVIg) have been used as an immunomodulatory therapy in a variety of diseases. Several mechanisms of action have been proposed, one of which is interference with the cytokine network. We have investigated the effect of IVIg on the cytotoxicity of human TNF alpha. IVIg was capable of protecting L929 fibroblasts from TNF alpha induced cell death. This effect was not species specific and was mediated by both the Fc and the Fab portion of immunoglobulins. Since the effect was also seen when IVIg was added after the removal of TNF alpha from the culture medium, it seems to be independent of the interaction of TNF alpha with its receptor. We conclude that IVIg either act on some point of the TNF alpha signalling pathway or influence the cell cycle unspecifically. The cytoprotective effect of IVIg potentially could contribute to the beneficial effect described for various diseases

Regulation of oxidative stress by glycaemic control: evidence for an independent inhibitory effect of insulin therapy

AIMS/HYPOTHESIS: We examined whether type of diabetes and/or insulin treatment can modulate the impact of sustained hyperglycaemia and glycaemic variability as activators of oxidative stress. METHODS: This was an observational study in 139 patients with diabetes, 48 with type 1, 60 with type 2 treated by oral hypoglycaemic agents (OHAs) alone and 31 with type 2 treated with insulin plus OHAs. In addition, two groups of ten patients with type 2 diabetes were investigated either before and after introducing insulin treatment (add-on insulin group) or before and after add-on OHA therapy to metformin (add-on OHA group). Oxidative stress was estimated from 24 h urinary excretion rates of 8-isoprostaglandin F2alpha (8-iso-PGF2alpha). HbA(1c) was assessed and mean amplitude of glycaemic excursions (MAGE) was estimated by continuous monitoring. RESULTS: The 24 h excretion rate of 8-iso-PGF2alpha (median [range] picomoles per millimole of creatinine) was much higher (p < 0.0001) in type 2 diabetes patients treated with OHAs alone (112 [26-329]) than in the type 1 diabetes group (65 [29-193]) and the type 2 diabetes group treated with insulin (69 [30-198]). It was associated with HbA(1c) (F = 12.9, p = 0.0008) and MAGE (F = 7.7, p = 0.008) in non-insulin-treated, but not in insulin-treated patients. A significant reduction in 24 h excretion rate of 8-iso-PGF2alpha from 126 (47-248) to 62 (35-111] pmol/mmol of creatinine was observed in the add-on insulin group (p = 0.005) but not in the add-on OHA group. CONCLUSIONS/INTERPRETATION: In type 1 and type 2 diabetes, insulin exerts an inhibitory effect on oxidative stress, a metabolic disorder that is significantly activated by sustained hyperglycaemia and glucose variability in non-insulin-treated type 2 diabetes

Patterns of eating behavior in people with severe obesity seeking weight loss treatment: An exploratory study

International audienceAlthough subjects with severe obesity need specific interventions, knowledge about their eating behavior, physical and mental health profiles remains insufficient. This cross-sectional study aimed to identify profiles of individuals with severe obesity based on clinical, psychological and eating behavior characteristics. We included 126 participants (103 women; mean age: 47.2 ± 13.9 years; mean BMI: 41.0 ± 5.7 kg/m2). Cluster analyses were performed to identify profiles based on age, waist circumference, eating behavior, depressive symptoms, food-related quality of life and physical activity. Metabolic syndrome components and type 2 diabetes prevalence were compared between the clusters. Three clusters were identified. Cluster 1 labeled struggling with food (48% of the population) had high scores on both emotional eating and uncontrolled eating, low score on comfort with food and they had depressive symptoms. Cluster 2, low loss of eating control (29%), had low scores on emotional eating and uncontrolled eating, and high quality of life in the psychosocial dimension. Cluster 3, pleasure from eating (22%), had the greatest score on comfort with food, the highest physical activity level, and depressive symptoms. In cluster 2, prevalence of type 2 diabetes was higher, although not statistically significant. Otherwise, no differences were found between clusters. Conclusion: Subjects with severe obesity have different profiles, partly explained by their eating behavior, associated with clinical and behavioral patterns. Further studies should confirm this cluster structure and assess how these profiles impact the evolution of obesity and whether they can help to improve the personalization of care programs
