Impact of Anesthesia Type on Outcomes of Transcatheter Aortic Valve Implantation (from the Multicenter ADVANCE Study).

Transcatheter aortic valve implantation (TAVI) has become the standard of care for many patients with symptomatic severe aortic stenosis who are at increased risk of morbidity and mortality during surgical aortic valve replacement. However, there is still no general consensus regarding the use of general anesthesia (GA) versus local anesthesia with sedation (non-GA) during the TAVI procedure. Using propensity score-matching analysis, we analyzed the characteristics and outcomes of patients who underwent TAVI with either GA (n = 245) or non-GA (n = 245) in the fully monitored, international, CoreValve ADVANCE Study. No statistically significant differences existed between the non-GA and GA groups in all-cause mortality (25.4% vs 23.9%, p = 0.78), cardiovascular mortality (16.4% vs 16.6%, p = 0.92), or stroke (5.2% vs 6.9%, p = 0.57) through 2-year follow-up. Major vascular complications were more common in the non-GA group. Total hospital stay was similar between the 2 groups. Conversion from non-GA to GA occurred in 13 patients (5.3%) because of procedural complications in 9 patients and discomfort or restlessness in 4 patients. Most procedural complications were related to valve positioning or vascular issues. Two of the 13 converted patients died during the procedure. Both GA and non-GA are widely used in real-world TAVI practice, and the decision appears to be guided by only a few patient-related factors and dominated by local and national practice. The outcomes of both anesthesia modes are equally good. When conversion from non-GA did occur, the complication requiring GA affected outcomes

Study protocol for a prospective, longitudinal cohort study investigating the medical and psychosocial outcomes of UK combat casualties from the Afghanistan war: the ADVANCE Study.

INTRODUCTION: The Afghanistan war (2003-2014) was a unique period in military medicine. Many service personnel survived injuries of a severity that would have been fatal at any other time in history; the long-term health outcomes of such injuries are unknown. The ArmeD SerVices TrAuma and RehabilitatioN OutComE (ADVANCE) study aims to determine the long-term effects on both medical and psychosocial health of servicemen surviving this severe combat related trauma. METHODS AND ANALYSIS: ADVANCE is a prospective cohort study. 1200 Afghanistan-deployed male UK military personnel and veterans will be recruited and will be studied at 0, 3, 6, 10, 15 and 20 years. Half are personnel who sustained combat trauma; a comparison group of the same size has been frequency matched based on deployment to Afghanistan, age, sex, service, rank and role. Participants undergo a series of physical health tests and questionnaires through which information is collected on cardiovascular disease (CVD), CVD risk factors, musculoskeletal disease, mental health, functional and social outcomes, quality of life, employment and mortality. ETHICS AND DISSEMINATION: The ADVANCE Study has approval from the Ministry of Defence Research Ethics Committee (protocol no:357/PPE/12) agreed 15 January 2013. Its results will be disseminated through manuscripts in clinical/academic journals and presentations at professional conferences, and through participant and stakeholder communications. TRIAL REGISTRATION NUMBER: The ADVANCE Study is registered at ISRCTN ID: ISRCTN57285353

Glycemic Effects of Once-a-Day Rapid-Acting Insulin Analogue Addition on a Basal Insulin Analogue in Korean Subjects with Poorly Controlled Type 2 Diabetes Mellitus

BackgroundThe present study investigates the efficacy in glycemic control by adding once-a-day glulisine to glargine as a basal plus regimen and factors influencing glycemic control with the basal plus regimen in Korean subjects with type 2 diabetes.MethodsIn the present retrospective study, subjects previously treated with the basal plus regimens for at least 6 months were reviewed. Changes in glycemic profiles and clinical parameters were evaluated.ResultsA total of 87 subjects were ultimately enrolled in this study. At baseline, mean glycated hemoglobin (A1c) and glycated albumin were 8.5% (8.0% to 9.6%) and 25.2±7.6%, respectively. After treatment with the basal plus regimen, patients had significant reductions of A1c at 6 months (0.8±0.1%, P<0.001) and their postprandial glucose levels were decreased by 48.7±10.3 mg/dL (P<0.001). Multiple logistic regression showed old age (odds ratio [OR], 1.25; 95% confidence interval [CI], 1.02 to 1.55), high initial A1c (OR, 22.21; 95% CI, 2.44 to 201.78), and lower amounts of glargine (OR, 0.85; 95% CI, 0.76 to 0.99), and glimepiride (OR, 0.23; 95% CI, 0.06 to 0.93) at baseline were independently associated with good responders whose A1c reduction was more than 0.5%.ConclusionThe authors suggest a basal plus regimen may be effective in reducing glucose levels of subjects with old age, high initial A1c, and patients on low doses of glimepiride and glargine. Despite the use of high doses of hypoglycemic agents, elderly patients with poorly-controlled diabetes are preferred for early initiation of the basal plus regimen

Epidemiology of Micro- and Macrovascular Complications of Type 2 Diabetes in Korea

The prevalence of diabetes in Korea has increased six- to sevenfold over the past 40 years with its complications becoming major causes of morbidity and mortality. The rate of death among patients with diabetes is about twice as high as that among persons without diabetes and the most common cause of death is cardiovascular disease (30.6%). Despite the seriousness of diabetic complications, 30 to 70% of patients receive inadequate care, and only 40% of treated diabetic patients achieve the optimal control with HbA1c level <7% in Korea. In 2006, over 30 to 40% of patients with diabetes have microvascular complications and around 10% of them have macrovascular complications from our national data. Despite there are some debates about intensive glycemic control resulting in the deterioration of macrovascular complication, multifactorial treatment approaches including proper glycemic control are important to prevent diabetic complications. There have been needs for finding proper biomarkers for predicting diabetic complications properly but we still need more longitudinal studies to find this correlation with causal relationship. In this article, we wanted to review the recent status of micro- and macrovascular complications of type 2 diabetes in Korea from integration of many epidemiologic studies

Relationship between combat-related traumatic injury and ultrashort term heart rate variability in a UK military cohort: findings from the ADVANCE study

Introduction Combat-related traumatic injury (CRTI) has been linked to an increased cardiovascular disease (CVD) risk. The long-term impact of CRTI on heart rate variability (HRV)—a robust CVD risk marker—has not been explored. This study investigated the relationship between CRTI, the mechanism of injury and injury severity on HRV. Methods This was an analysis of baseline data from the ArmeD SerVices TrAuma and RehabilitatioN OutComE (ADVANCE) prospective cohort study. The sample consisted of UK servicemen with CRTI sustained during deployment (Afghanistan, 2003–2014) and an uninjured comparison group who were frequency matched to the injured group based on age, rank, deployment period and role in theatre. Root mean square of successive differences (RMSSD) was measured as a measure of ultrashort term HRV via <16 s continuous recording of the femoral arterial pulse waveform signal (Vicorder). Other measures included injury severity (New Injury Severity Scores (NISS)) and injury mechanism. Results Overall, 862 participants aged 33.9±5.4 years were included, of whom 428 (49.6%) were injured and 434 (50.3%) were uninjured. The mean time from injury/ deployment to assessment was 7.91±2.05 years. The median (IQR) NISS for those injured was 12 (6–27) with blast being the predominant injury mechanism (76.8%). The median (IQR) RMSSD was significantly lower in the injured versus the uninjured (39.47 ms (27.77–59.77) vs 46.22 ms (31.14–67.84), p<0.001). Using multiple linear regression (adjusting for age, rank, ethnicity and time from injury), geometric mean ratio (GMR) was reported. CRTI was associated with a 13% lower RMSSD versus the uninjured group (GMR 0.87, 95% CI 0.80–0.94, p<0.001). A higher injury severity (NISS ≥25) (GMR 0.78, 95% CI 0.69–0.89, p<0.001) and blast injury (GMR 0.86, 95% CI 0.79–0.93, p<0.001) were also independently associated with lower RMSSD. Conclusion These results suggest an inverse association between CRTI, higher severity and blast injury with HRV. Longitudinal studies and examination of potential mediating factors in this CRTI-HRV relationship are needed

Comparison of Vildagliptin-Metformin and Glimepiride-Metformin Treatments in Type 2 Diabetic Patients

BackgroundThe present study investigated the efficacy and safety of vildagliptin-metformin treatment compared to those of glimepiride-metformin treatment for type 2 diabetes.MethodsIn a randomized, open-label, comparative study, 106 patients with type 2 diabetes were enrolled. The primary endpoint was a reduction in HbA1c from baseline and secondary endpoints included fasting plasma glucose (FPG) or 2-hour postprandial glucose (2h-PPG) reduction from baseline, as well as HbA1c responder rate and HbA1c reduction according to baseline HbA1c category.ResultsComparable HbA1c reduction was observed with a mean±standard deviation change from baseline to the 32-week endpoint of -0.94±1.15% in the vildagliptin group and -1.00±1.32% in the glimepiride group. A similar reduction in 2h-PPG (vildagliptin group 3.53±4.11 mmol/L vs. the glimepiride group 3.72±4.17 mmol/L) was demonstrated, and the decrements in FPG (vildagliptin group 1.54±2.41 mmol/L vs. glimepiride group 2.16±2.51 mmol/L) were not different between groups. The proportion of patients who achieved an HbA1c less than 7% at week 32 was 50.1% in the vildagliptin group and 56.0% in the glimepiride group. An average body weight gain of 2.53±1.21 kg in the glimepiride group was observed in contrast with the 0.23±0.69 kg weight gain noted in the vildagliptin group. A 10-fold lower incidence of hypoglycemia was demonstrated in the vildagliptin group, in addition to an absence of severe hypoglycemia.ConclusionVildagliptin-metformin treatment provided blood glucose control efficacy comparable to that of glimepiride-metformin treatment and resulted in better adverse event profiles with lower risks of hypoglycemia and weight gain

The management of type 2 diabetes with fixed‐ratio combination insulin degludec/liraglutide (IDegLira) versus basal‐bolus therapy (insulin glargine U100 plus insulin aspart): a short‐term cost‐effectiveness analysis in the UK setting

Aim: To evaluate the cost‐effectiveness of IDegLira versus basal‐bolus therapy (BBT) with insulin glargine U100 plus up to 4 times daily insulin aspart for the management of type 2 diabetes in the UK. Methods: A Microsoft Excel model was used to evaluate the cost‐utility of IDegLira versus BBT over a 1‐year time horizon. Clinical input data were taken from the treat‐to‐target DUAL VII trial, conducted in patients unable to achieve adequate glycaemic control (HbA1c &lt;7.0%) with basal insulin, with IDegLira associated with lower rates of hypoglycaemia and reduced body mass index (BMI) in comparison with BBT, with similar HbA1c reductions. Costs (expressed in GBP) and event‐related disutilities were taken from published sources. Extensive sensitivity analyses were performed. Results: IDegLira was associated with an improvement of 0.05 quality‐adjusted life years (QALYs) versus BBT, due to reductions in non‐severe hypoglycaemic episodes and BMI with IDegLira. Costs were higher with IDegLira by GBP 303 per patient, leading to an incremental cost‐effectiveness ratio (ICER) of GBP 5924 per QALY gained for IDegLira versus BBT. ICERs remained below GBP 20 000 per QALY gained across a range of sensitivity analyses. Conclusions: IDegLira is a cost‐effective alternative to BBT with insulin glargine U100 plus insulin aspart, providing equivalent glycaemic control with a simpler treatment regimen for patients with type 2 diabetes inadequately controlled on basal insulin in the UK

Exenatide compared with long-acting insulin to achieve glycaemic control with minimal weight gain in patients with type 2 diabetes: results of the Helping Evaluate Exenatide in patients with diabetes compared with Long-Acting insulin (HEELA) study

Aim: The Helping Evaluate Exenatide in overweight patients with diabetes compared with Long-Acting insulin (HEELA) study was designed to examine whether the glucagon-like peptide-1 (GLP-1) receptor agonist, exenatide, could improve HbA1c (≤7.4%) with minimal weight gain (≤1 kg) compared with insulin glargine

An observational study of patient characteristics and mortality following hypoglycemia in the community

Objectives: Characterize diabetes patients with severe hypoglycemia requiring emergency services intervention at home and investigate 12 month mortality. Research design and methods: Emergency services call-outs for hypoglycemia were recorded between 2005 and 2013 in an area covering 34000 patients with diabetes. Patient characteristics were documented together with capillary blood glucose (CBG), HbA1c and treatment for hypoglycemia. 12 month mortality and variables influencing survival were analysed. Results: In 1835 episodes amongst 1156 patients, 45% had type 1 diabetes (68.2% males), 44% had type 2 diabetes (49.4% males) with a minority unclassified. CBG at presentation (mean±SD) was 1.76±0.72 mmol/L in type 1 diabetes and 1.96±0.68 mmol/L in type 2 diabetes patients (p<0·0001), with higher HbA1c in the former group (8.3±1.52% (67.5±16.4 mmol/mol) and 7.8±1.74% (61.6±19.0 mmol/mol), respectively; p<0·0001). A third of type 2 diabetes patients were not on insulin therapy and displayed lower HbA1c compared with insulin users. Glucagon was used in 37% of type 1 diabetes and 28% of type 2 diabetes patients (p<0.0001). One year mortality was 4.45% in type 1 diabetes and 22.1% in type 2 diabetes. Age and type of diabetes were predictive of mortality in multivariable analysis, whereas CBG levels/frequency of hypoglycemia had no effect. Conclusions: Severe hypoglycemia in the community is common with a male predominance in type 1 diabetes. Severe hypoglycemia in non-insulin treated type 2 diabetes patients is associated with lower HbA1c compared with insulin users. Severe hypoglycemia appears to be associated with increased mortality at 12 months, particularly in type 2 diabetes. KEY MESSAGES Severe hypoglycemia in the community is common, and presents a large burden on both patients and healthcare workers. Using a large database of ambulance call-outs for hypoglycemia this study aimed to characterise those requiring the emergency services for an episode of hypoglycemia, and to investigate factors that may be associated with an increased risk of mortality. We found that a third of type 2 diabetes patients having severe hypoglycemic episodes were not using any insulin, these individuals had a lower HbA1c than those with type 2 diabetes requiring insulin treatment. 12 month mortality following an episode of severe hypoglycemia was high, especially in individuals with type 2 diabetes. More research is required to investigate the cause of death in these patient

ADVANCE-TBI study protocol: traumatic brain injury outcomes in UK military personnel serving in Afghanistan between 2003 and 2014 - a longitudinal cohort study

INTRODUCTION: Outcomes of traumatic brain injury (TBI) are highly variable, with cognitive and psychiatric problems often present in survivors, including an increased dementia risk in the long term. Military personnel are at an increased occupational risk of TBI, with high rates of complex polytrauma including TBI characterising the UK campaign in Afghanistan. The ArmeD SerVices TrAuma and RehabilitatioN OutComE (ADVANCE)-TBI substudy will describe the patterns, associations and long-term outcomes of TBI in the established ADVANCE cohort. METHODS AND ANALYSIS: The ADVANCE cohort comprises 579 military personnel exposed to major battlefield trauma requiring medical evacuation, and 566 matched military personnel without major trauma. TBI exposure has been captured at baseline using a standardised interview and registry data, and will be refined at first follow-up visit with the Ohio State Method TBI interview (a National Institute of Neurological Disorders and Stroke TBI common data element). Participants will undergo blood sampling, MRI and detailed neuropsychological assessment longitudinally as part of their follow-up visits every 3-5 years over a 20-year period. Biomarkers of injury, neuroinflammation and degeneration will be quantified in blood, and polygenic risk scores calculated for neurodegeneration. Age-matched healthy volunteers will be recruited as controls for MRI analyses. We will describe TBI exposure across the cohort, and consider any relationship with advanced biomarkers of injury and clinical outcomes including cognitive performance, neuropsychiatric symptom burden and function. The influence of genotype will be assessed. This research will explore the relationship between military head injury exposure and long-term outcomes, providing insights into underlying disease mechanisms and informing prevention interventions. ETHICS AND DISSEMINATION: The ADVANCE-TBI substudy has received a favourable opinion from the Ministry of Defence Research Ethics Committee (ref: 2126/MODREC/22). Findings will be disseminated via publications in peer-reviewed journals and presentations at conferences
