AIM To report the results of a 104-week extension to a 52-week study in which dapagliflozin plus saxagliptin (DAPA+SAXA) improved glycaemic control, liver fat and metabolic variables compared with glimepiride (GLIM) in participants with type 2 diabetes (T2D) receiving background metformin. MATERIALS AND METHODS This extension to a 52-week global, multicentre, parallel-group, active-controlled, double-blind study (NCT02419612) continued randomized participants (1:1) on DAPA+SAXA (10/5 mg) plus placebo, or GLIM (1-6 mg) plus placebo, once daily. Eligible participants were aged ≥18 years, had T2D (glycated haemoglobin [HbA1c] 58.5-91.3 mmol/mol [7.5%-10.5%]), and a body mass index of 20.0 to 45.0 kg/m2 , and were receiving metformin (MET; ≥1500 mg/d). Key outcomes were: requirement for treatment intensification, based on HbA1c ≥53 mmol/mol (7%); achieving therapeutic glycaemic response; and changes in adipose tissue and liver fat on magnetic resonance imaging in a substudy. RESULTS Overall, 382 participants entered and 338 completed the 104-week extension period (MRI substudy, n = 82). The need for treatment intensification during the 156-week period was lower for DAPA+SAXA+MET (37.0%) than GLIM+MET (55.6%; hazard ratio 0.52, 95% confidence interval [CI] 0.39-0.68; P

The 2008 ICSH guideline was proposed to bring uniformity in bone marrow reporting among pathologists worldwide. The objective was to study the usefulness of on-site procedural information in routine marrow reporting. The nature of marrow aspirate, gross appearance, and core length of iliac crest trephine biopsies from 174 consecutive subjects (109 males, 65 females, mean age 47.5 ± 19.2 years) were reviewed by a pathologist blinded to the final diagnosis. The nature of aspirate had a significant correlation with a positive diagnostic yield among 149/176 (84.6%) cases (P = 0.03). Among cytopenic subjects, megaloblastic anemias (MA) (N = 27) and aplastic anemias (AA) (N = 14) had richly particulate and greasy/fat rich aspirates, respectively (P

Aim To examine the long‐term efficacy and safety of dapagliflozin, a sodium‐glucose co‐transporter‐2 (SGLT2) inhibitor used to treat type 1 diabetes, in the Japanese subpopulation of the DEPICT‐2 study. Materials and Methods Patients with type 1 diabetes were randomized to dapagliflozin 5 mg (n = 55), dapagliflozin 10 mg (n = 41) or placebo (n = 58) plus insulin for a 24‐week, double‐blind period followed by a 28‐week, single‐blind extension phase. Results From baseline to 24 weeks, dapagliflozin reduced HbA1c compared with placebo (mean change of −0.58% and −0.80% for 5 and 10 mg, respectively), and an HbA1c reduction was observed up to 52 weeks. Compared with placebo, dapagliflozin 5 and 10 mg increased the proportion of patients achieving HbA1c reductions of 0.5% or more without severe hypoglycaemia events and reduced glycaemic variability assessed via continuous glucose monitoring. Both dapagliflozin doses decreased body weight and total daily insulin dose at 24 weeks compared with placebo; these reductions were maintained up to 52 weeks. Diabetic ketoacidosis occurred in both dapagliflozin groups (one and two cases, respectively) but not with placebo. Conclusions Efficacy and safety results from the Japanese subpopulation of the DEPICT‐2 study were generally consistent with those from the overall population, indicating that long‐term dapagliflozin adjunct to insulin therapy improves glycaemic control without an increased risk of hypoglycaemia but with a risk of diabetic ketoacidosis in Japanese patients with type 1 diabetes.

Aims This pooled analysis of the DEPICT-1 and -2 trials aimed to evaluate the efficacy and safety of adjunct dapagliflozin therapy in patients with type 1 diabetes (T1D). Materials and methods DEPICT-1 and -2 were randomized, double-blind, parallel-group, 24-week studies, with 28-week extension periods. Adults with T1D and HbA1c 7.5-10.5% were randomized (1:1:1) to receive dapagliflozin 5, 10 mg or placebo. The short- and long-term efficacy and safety of dapagliflozin were examined in an exploratory pooled analysis of both studies. Results Efficacy analyses included 530, 529 and 532 and safety analysis included 548, 566 and 532 patients in the dapagliflozin 5 mg, 10 mg and placebo groups, respectively. Baseline characteristics were similar between treatment groups. At Week 24, reductions were seen with dapagliflozin 5 and 10 mg compared with placebo in HbA1c (-0.40%, -0.43% vs 0.00%) and body weight (-2.45, -2.91 vs 0.11 kg). HbA1c and body weight reductions versus placebo were also seen after 52 weeks of treatment. There was no imbalance in occurrence of severe hypoglycaemic events between groups. The proportion of patients experiencing definite diabetic ketoacidosis (DKA) was higher with dapagliflozin 5 mg (4.0%) and 10 mg (3.5%) compared with placebo (1.1%) over 52 weeks; most events were of mild or moderate severity, and all resolved with treatment. Conclusions Over 52 weeks, dapagliflozin provided glycaemic and weight benefits, with no increased frequency of severe hypoglycaemia compared with placebo. More DKA events were reported with dapagliflozin than placebo, highlighting the importance of appropriate patient selection, education and risk mitigation strategies.

Summary Background The DEPICT-1 and DEPICT-2 studies showed that dapagliflozin as an adjunct to insulin in individuals with inadequately controlled type 1 diabetes improved glycaemic control and bodyweight, without increase in risk of hypoglycaemia. We aimed to determine the effect of dapagliflozin on urinary albumin-to-creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR) using pooled data from the DEPICT studies. Methods In this post-hoc analysis, we used data pooled from both DEPICT studies (DEPICT-1 ran from Nov 11, 2014, to Aug 25, 2017; DEPICT-2 ran from July 8, 2015, to April 18, 2018), in which participants were aged 18–75 years, with inadequately controlled type 1 diabetes and with a baseline UACR of at least 30 mg/g. In the DEPICT studies, participants were randomly assigned (1:1:1) to receive dapagliflozin (5 mg or 10 mg) or placebo all plus insulin, for 24 weeks, with a 28-week long-term extension (ie, 52 weeks in total). In this post-hoc analysis, we assessed the percentage change from baseline in UACR and in eGFR, up to 52 weeks. UACR, eGFR, and safety were assessed in all eligible participants who had received at least one dose of study drug. HbA1c, bodyweight, and systolic blood pressure were assessed in all participants who received at least one dose of study drug during the first 24-week period, and who had a baseline and any post-baseline assessment for that parameter. The DEPICT trials were registered with ClinicalTrials.gov , NCT02268214 (DEPICT-1), NCT02460978 (DEPICT-2), and are now complete. Results 251 participants with albuminuria at baseline were included in this post-hoc analysis; of whom 80 (32%) had been randomly assigned to dapagliflozin 5 mg, 84 (33%) to dapagliflozin 10 mg, and 87 (35%) to placebo. Compared with placebo, treatment with both dapagliflozin doses improved UACR over 52 weeks. At week 52, mean difference in change from baseline versus placebo in UACR was −13·3% (95% CI −37·2 to 19·8) for dapagliflozin 5 mg and −31·1% (−49·9 to −5·2) for dapagliflozin 10 mg. No notable change from baseline was seen in eGFR, with a mean difference in change from baseline versus placebo of 3·27 mL/min per 1·73 m2 (95% CI −0·92 to 7·45) for dapagliflozin 5 mg and 2·12 mL/min per 1·73 m2 (–2·03 to 6·27) for dapagliflozin 10 mg. Similar proportions of participants in each treatment group had adverse events and serious adverse events, including hypoglycaemia and diabetic ketoacidosis; no new safety signals were identified in this population. Interpretation Treatment with dapagliflozin resulted in UACR reduction, which might provide renoprotective benefits in individuals with type 1 diabetes and albuminuria. Dedicated prospective studies are needed to confirm these findings as prespecified endpoints. Funding AstraZeneca.

Background: EXSCEL (Exenatide Study of Cardiovascular Event Lowering) assessed the impact of once-weekly exenatide 2 mg versus placebo in patients with type 2 diabetes mellitus, while aiming for glycemic equipoise. Consequently, greater drop-in of open-label glucose-lowering medications occurred in the placebo group. Accordingly, we explored the potential effects of their unbalanced use on major adverse cardiovascular events (MACE), defined as cardiovascular death, nonfatal myocardial infarction or nonfatal stroke, and all-cause mortality (ACM), given that some of these agents are cardioprotective. Methods: Cox hazard models were performed by randomized treatment for drug classes where >5% open-label drop-in glucose-lowering medication occurred, and for glucagon-like peptide-1 receptor agonists (GLP-1 RAs; 3.0%) using three methodologies: drop-in visit right censoring, inverse probability for treatment weighting (IPTW), and applying drug class risk reductions. Results: Baseline glucose-lowering medications for the 14 752 EXSCEL participants (73.1% with previous cardiovascular disease) did not differ between treatment groups. During median 3.2 years follow-up, open-label drop-in occurred in 33.4% of participants, more frequently with placebo than exenatide (38.1% versus 28.8%), with metformin (6.1% versus 4.9%), sulfonylurea (8.7% versus 6.9%), dipeptidyl peptidase-4 inhibitors (10.6% versus 7.5%), SGLT-2i (10.3% versus 8.1%), GLP-1 RA (3.4% versus 2.4%), and insulin (13.8% versus 9.4%). The MACE effect size was not altered meaningfully by right censoring, but the favorable HR for exenatide became nominally significant in the sulfonylurea and any glucose-lowering medication groups, while the ACM HR and p-values were essentially unchanged. IPTW decreased the MACE HR from 0.91 ( P =0.061) to 0.85 ( P =0.008) and the ACM HR from 0.86 ( P =0.016) to 0.81 ( P =0.012). Application of literature-derived risk reductions showed no meaningful changes in MACE or ACM HRs or P values, although simulations of substantially greater use of drop-in cardioprotective glucose-lowering agents demonstrated blunting of signal detection. Conclusions: EXSCEL-observed HRs for MACE and ACM remained robust after right censoring or application of literature-derived risk reductions, but the exenatide versus placebo MACE effect size and statistical significance were increased by IPTW. Effects of open-label drop-in cardioprotective medications need to be considered carefully when designing, conducting, and analyzing cardiovascular outcome trials of glucose-lowering agents under the premise of glycemic equipoise.

Over the past two decades, gene expression profiling of breast cancer has emerged as an important tool in early-stage breast cancer management. The approach provides important information on underlying biological mechanisms, breast cancer classification, future risk potential of developing recurrent metastatic disease, and provides beneficial clues for adjuvant chemotherapy in hormone receptor (HR) positive breast cancer. Of the commercially available genomic tests for breast cancer, the prognostic and predictive value of 21-gene recurrence score tests have been validated using both retrospective data and prospective clinical trials. In this paper, we reviewed the current evidence on 21-gene expression profiles for HR-positive HER2-negative early-stage breast cancer management. We show that current evidence supports endocrine therapy alone as an appropriate adjuvant systemic therapy for approximately 70% of women with HR-positive, HER2-negative, node-negative breast cancer. Evolving evidence also suggests that 21-gene recurrence scores have predictive values for node-positive breast cancer and that chemotherapy can be avoided in more than half of women with nodes 1 to 3 positive HR-positive breast cancer. Furthermore, retrospective data also supports the predictive role of 21-gene recurrence scores for adjuvant radiation therapy. A prospective trial in this area is ongoing.

BACKGROUND One of the most common forms of central nervous tuberculosis is tubercular meningitis and has high morbidity and mortality. The natural course of TBM is subacute in nature; hence, the symptoms may persist for weeks before diagnosis. The diagnosis of tuberculosis is based on clinical presentation and cerebrospinal fluid analysis. GeneXpert is a reliable and rapid diagnostic modality for diagnosing pulmonary tuberculosis. Various studies have shown various sensitivity patterns of GeneXpert in TBM. This study aims to find the utility of GeneXpert in TBM. METHODS All adult patients who presented with signs and symptoms of meningitis were included in the study. Detailed history was recorded and physical examination done. All patients were subjected to routine blood investigations, chest X ray, brain imaging along with lumbar puncture for cerebrospinal fluid (CSF) analysis. Apart from routine CSF analysis for cell type, cell count, and biochemical analysis, 3-5 ml of CSF was sent for GeneXpert to intermediate reference laboratory at Government Hospital for Chest Diseases, Pondicherry. On the basis of clinical history, examination, and investigations, composite gold standard for the diagnosis of TBM was defined. The composite gold standard included definite case of TBM, highly probable case of TBM, probable case of TBM and definitely not TBM. Sensitivity and specificity were calculated for GeneXpert for the composite gold standard. RESULTS 100 patients were included in the study. 64 were males and 36 were females. TBM was detected in 22 cases. Mean age for TBM was 42 ± 19.2 years. Among 22 cases of TBM, only one case was categorized as definite TBM, and the rest 21 were either highly probable TBM (7) or probable TBM cases (14). Common clinical signs and symptoms on presentation were headache (87%), fever (78%), neck rigidity (69%), seizure (52%) and altered sensorium (74%). GeneXpert and CSF culture was positive in only one case with sensitivity of 14% and specificity of 100%. Adenosine deaminase (ADA) was high in 13 cases with sensitivity of 60% and specificity of 100%. CONCLUSIONS The utility of GeneXpert in diagnosing tubercular meningitis is very insignificant. Negative GeneXpert in CSF analysis does not rule out TBM as sensitivity is 14% but positive GeneXpert has 100% specificity. In the absence of reliable diagnostic test, clinician should look for specific signs and symptoms of meningitis along with routine CSF analysis and CSF ADA level.

Introduction: The ideal method to teach evidence-based medicine (EBM) to medical students is unclear. We determined the effectiveness of a simulated randomized controlled trial (RCT) in improving critical appraisal and EBM skills among medical students compared to traditional training. Methods: One hundred and eighteen medical students were randomized into two groups. Sixty-one students (immersion arm) were trained in critical appraisal using a simulated RCT aimed at determining efficacy of a “brainy pill” on ability to crack puzzles. Fifty-seven students (traditional group) were trained using a journal club with a checklist. Primary outcome of change in knowledge and skills of critical appraisal and EBM was determined by comparing scores on pre- and post-intervention Fresno tests. Results: Mean age of students was 21.76 (SD - 0.78) years. Seventy (59.3%) were females and 48 (40.7%) males. Mean pre-test scores of traditional and immersion groups were 8.0 (SD - 4.88) and 9.31 (SD - 5.49) respectively and post-test scores were 50.2 (SD - 16.2) and 68.12 (SD - 14.72) respectively (post-intervention mean difference - 17.92; 95% CI 12.26 - 23.57; p

Background: Once-weekly exenatide (EQW) had a neutral effect on hospitalization for heart failure (HHF) in the EXSCEL study (Exenatide Study of Cardiovascular Event Lowering), with no differential treatment effect on major adverse cardiac events by baseline heart failure (HF) status. EQW’s effects on secondary end points based on HHF status have not been reported. The objective was to explore the effects of EQW on secondary end points in patients with and without baseline HF and test the effects of EQW on recurrent HHF events. Methods: The prespecified analysis of the randomized controlled EXSCEL trial, which enrolled patients with type 2 diabetes mellitus with and without additional cardiovascular disease, analyzed EQW effects on all-cause death, each major adverse cardiac event component, first HHF, and repeat HHF, by baseline HF status (regardless of ejection fraction). A subgroup analysis of the population stratified by preserved or reduced baseline ejection fraction was performed. Results: Of 14 752 EXSCEL participants, 2389 (16.2%) had HF at baseline. Compared with those without HF at baseline, patients with preexisting HF were older, and more likely to be male and white, with a higher burden of other cardiovascular diseases. Overall, those assigned to EQW had a lower incidence of all-cause death (hazard ratio [HR], 0.86 [95% CI, 0.77–0.97]) and the composite outcome of all-cause death or HHF (HR, 0.89 [95% CI, 0.80–0.99]). When stratified by presence or absence of baseline HF, there was no observed reduction in all-cause death with EQW with baseline HF (HR, 1.05 [95% CI, 0.85–1.29]), while the risk of mortality was reduced with EQW in the no-HF group (HR, 0.79 [95% CI, 0.68–0.92]) with an interaction P value of 0.031. The reduction in all-cause death or HHF seen with EQW in patients without baseline HF (HR, 0.81 [95% CI, 0.71–0.93]) was not seen in patients with baseline HF (HR, 1.07 [95% CI, 0.89–1.29]; interaction P =0.015). First, plus recurrent, HHF was reduced in the exenatide group versus placebo (HR, 0.82 [95% CI, 0.68–0.99]; P =0.038). Conclusions: In EXSCEL, the use of EQW in patients with or without HF was well tolerated, but benefits of EQW on reduction in all-cause death and first hospitalization for HF were attenuated in patients with baseline HF.

Introduction Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are widely used for treatment of type 2 diabetes mellitus; however, there have been concerns that GLP-1RA treatment may be associated with an increased incidence of pancreatitis. This study aimed to evaluate the incidence of pancreatitis in a pooled population of type 2 diabetes trials from the clinical development program of the GLP-1RA exenatide as well as to describe patient-level data for all reported cases. Methods The primary analysis examined pooled data among patients with type 2 diabetes from the controlled arms of 35 trials (ranging from 4 to 234 weeks’ duration) in the integrated clinical databases for exenatide twice daily, once weekly, and once-weekly suspension, excluding comparator arms with other incretin-based therapies. The exposure-adjusted incidence rate (EAIR) of pancreatitis was calculated for exenatide and non-exenatide (non-incretin-based therapy or placebo) treatment groups. Patient-level data were described for all pancreatitis incidences. Results The primary analysis included 5596 patients who received exenatide and 4462 in the non-exenatide group. The mean duration of study medication exposure for the exenatide and non-exenatide treatment groups was 57.0 and 47.9 weeks, respectively. Pancreatitis was diagnosed in 14 patients (exenatide, n = 8; non-exenatide, n = 6), of whom 13 recovered with or without sequelae. The pancreatitis EAIR was 0.1195 events per 100 patient-years [95% confidence interval (CI), 0.0516–0.2154] in the exenatide group versus 0.1276 events per 100 patient-years (95% CI 0.0468–0.2482) in the non-exenatide treatment group. The EAIR ratio for the exenatide versus non-exenatide treatment group was 0.761 (95% CI 0.231–2.510). Conclusion In this pooled analysis of 10,058 patients among studies comparing exenatide with other glucose-lowering medications or placebo, pancreatitis was rare. The EAIRs of pancreatitis were low and similar between exenatide and non-exenatide treatment groups. No evidence of an association between exenatide and pancreatitis was observed.

OBJECTIVE Increases in serum calcitonin, a tumor marker for medullary thyroid carcinoma (MTC), have been associated with glucagon-like peptide 1 receptor agonist use in some preclinical studies. We report calcitonin changes in exenatide-treated and placebo-administered participants and MTC incidence in the EXenatide Study of Cardiovascular Event Lowering (EXSCEL) and consider the impact of within-trial calcitonin monitoring. RESEARCH DESIGN AND METHODS EXSCEL participants were randomized 1:1 to once-weekly exenatide 2 mg or placebo. Serum calcitonin was measured at baseline (with trial medication discontinued if >40 ng/L) and annually thereafter (with trial medication discontinued if ≥50 ng/L). Median calcitonin concentrations were calculated at each time point, and thyroid malignancies were collected prospectively. Data regarding follow-up after an elevated calcitonin were collected retrospectively. RESULTS At baseline, 52 (30 exenatide and 22 placebo) participants had calcitonin >40 ng/L, and during follow-up an additional 23 participants (15 exenatide and 8 placebo) had calcitonin ≥50 ng/L in the intention-to-treat population. Median calcitonin concentrations were similar between treatment groups at baseline with no increase over time. Confirmed MTC occurred in three participants (2 exenatide and 1 placebo), all of whom had significantly elevated baseline calcitonin values (413, 422, and 655 ng/L). CONCLUSIONS During a median 3.2 years’ follow-up, no change in serum calcitonin was seen with exenatide therapy. The three confirmed cases of MTC all occurred in participants with markedly elevated baseline calcitonin levels, measured prior to trial medication administration. Regular calcitonin monitoring identified no additional cases of MTC, suggesting no benefit of routine calcitonin monitoring during exenatide treatment.

Aims To investigate the glycemic efficacy, effects on cardiovascular risk factors, and safety of exenatide once weekly (QW) in patients with type 2 diabetes over 7 years in the DURATION-1 study. Methods Patients were initially randomized to exenatide QW 2 mg or exenatide twice daily for 30 weeks, after which they received open-label, open-ended treatment with exenatide QW 2 mg for up to 7 years. Efficacy analyses included changes from baseline in glycated hemoglobin (HbA1C) and cardiovascular risk factors. Results Of 295 patients in the intention-to-treat population, 122 (41%) completed 7 years of treatment. Patients in the 7-year completer population showed sustained glycemic improvements from baseline (7-year least-squares mean [LSM] change in HbA1C, −1.53%) and significant improvements in several cardiovascular risk factors, including body weight, diastolic blood pressure, total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol. Seven-year completers who received no additional glucose-lowering therapies (n = 65 [53%]) had similar improvements in HbA1C, and numerically greater reductions in body weight (7-year LSM change, −6.46 kg vs −3.87 kg), compared with the overall cohort. There were no unexpected safety findings. Conclusions Treatment with exenatide QW for 7 years was associated with sustained improvements in glycemic control and several cardiovascular risk factors.

Five-year clinico-laboratory data from 99 (one HIV seropositive) adults (mean age = 41.3 ± 20.4 years) who underwent bone marrow examination for fever persisting for ≥ 1 week were analysed and correlated with microbiological characteristics. Infections, reactive marrow changes and haematolymphoid malignancies were most commonly associated with fever. A high concordance rate of 71% was noted between aspiration and trephine biopsies. Bone marrow granulomas (BMG) were seen exclusively on sections and were most commonly of tubercular and typhoidal in origin (two Salmonella Typhi, one Salmonella Paratyphi A). The common aetiologies associated with fever and cytopenia(s) were BMG, acute leukaemia and haemophagocytic lymphohistiocytosis (HLH; n = 3). The yield from bone marrow culture was inferior compared to other body fluids. In conclusion, bone marrow histology is superior to smears in the evaluation of prolonged fever. Marrow culture may not be useful in immunocompetent individuals other than if Salmonellosis is suspected.

AIMS: To compare the efficacy and safety of an intensification strategy of early triple combination therapy with dapagliflozin (DAPA) plus saxagliptin (SAXA) to a dual therapy strategy with sitagliptin (SITA) in patients with type 2 diabetes who are inadequately controlled with metformin (MET) monotherapy. MATERIALS AND METHODS: This multinational, active-controlled, parallel-group phase 3b trial randomized 461 patients, at least 18 years of age, with glycated haemoglobin (HbA1c) of 8%-10.5% (64-91 mmol/mol), to either DAPA plus SAXA or SITA, added to MET, for a 26-week double-blind treatment period and an extension of a 26-week blinded treatment period. RESULTS: Mean (± SD) baseline HbA1c was 8.8% ± 0.9% (73.0 ± 9.3 mmol/mol). DAPA plus SAXA (n = 232) provided a greater reduction from baseline in HbA1c at Weeks 26 and 52 compared with SITA (n = 229) (adjusted mean ± SE change, Week 26: -1.41 ± 0.07% vs -1.07 ± 0.07% [-15.4 ± 0.8 mmol/mol vs 11.7 ± 0.8 mmol/mol]; P = 0.0008; Week 52: -1.29 ± 0.08% vs -0.81 ± 0.09% [14.1 ± 0.9 mmol/mol vs 8.9 ± 1.0 mmol/mol]). The between-group difference in adjusted mean (95% CI) change from baseline in HbA1c increased from -0.34 (-0.54, -0.14) at Week 26 to -0.48 (-0.71, -0.25) at Week 52. DAPA plus SAXA was generally well tolerated and the incidence of adverse events was similar in both treatment arms. CONCLUSIONS: Early intensification to triple therapy with DAPA plus SAXA results in better, more durable glycaemic control than addition of SITA only (dual therapy) in patients with high HbA1c levels who are uncontrolled with MET monotherapy. ispartof: DIABETES OBESITY & METABOLISM vol:21 issue:4 pages:883-892 ispartof: location:England status: published

AIMS: Although models exist to predict amputation among people with type 2 diabetes with foot ulceration or infection, we aimed to develop a prediction model for a broader range of major adverse limb events (MALE)—including gangrene, revascularization, and amputation—among individuals with type 2 diabetes. METHODS: In a post-hoc analysis of data from the Exenatide Study of Cardiovascular Event Lowering (EXSCEL) trial, we compared participants who experienced MALE with those who did not. A multivariable model was constructed and translated into a risk score. RESULTS: Among the 14,752 participants with type 2 diabetes in EXSCEL, 3.6% experienced MALE. Characteristics associated with increased risk of MALE were peripheral artery disease (PAD) (HR(adj) 4.83, 95% CI 3.94–5.92), prior foot ulcer (HR(adj) 2.16, 95% CI 1.63–2.87), prior amputation (HR(adj) 2.00, 95% CI 1.53–2.64), current smoking (HR(adj) 2.00, 95% CI 1.54–2.61), insulin use (HR(adj) 1.86, 95% CI 1.52–2.27), coronary artery disease (HR(adj) 1.67, 95% CI 1.38–2.03), and male sex (HR(adj) 1.64, 95% CI 1.31–2.06). Cerebrovascular disease, former smoking, age, glycated haemoglobin, race, and neuropathy were also associated significantly with MALE after adjustment. A risk score ranging from 6-96 points was constructed, with a C-statistic of 0.822 (95% CI 0.803–0.841). CONCLUSIONS: The majority of MALE occurred among participants with PAD, but participants without a history of PAD also experienced MALE. A risk score with good performance was generated. Although it requires validation in an external dataset, this risk score may be valuable in identifying patients requiring more intensive care and closer follow-up.

Software products in the market are changing due to changes in business processes, technology, or new requirements from the customers. Maintainability of legacy systems has always been an inspiring task for the software companies. In order to determine whether the software requires maintainability by reverse engineering or by forward engineering approach, a system assessment was done from diverse perspectives: quality, business value, type of errors, etc. In this research, the changes required in the existing software components of the legacy system were identified using a supervised learning approach. New interfaces for the software components were redesigned according to the new requirements and/or type of errors. Software maintainability was measured by applying a machine learning technique, i.e., Na&iuml, ve Bayes classifier. The dataset was designed based on the observations such as component state, successful or error type in the component, line of code of error that exists in the component, component business value, and changes required for the component or not. The results generated by the Waikato Environment for Knowledge Analysis (WEKA) software confirm the effectiveness of the introduced methodology with an accuracy of 97.18%.

AIM: To investigate the long-term efficacy and safety of dapagliflozin as an adjunct to adjustable insulin in adults with type 1 diabetes (T1D) and inadequate glycaemic control. MATERIALS AND METHODS: Dapagliflozin Evaluation in Patients with Inadequately Controlled Type 1 Diabetes (DEPICT-2) was a placebo-controlled, double-blind, multicentre, phase III study of adults with T1D (HbA1c 7.5%-10.5%) randomized (1:1:1) to receive dapagliflozin 5, 10 mg, or placebo. The efficacy and safety of dapagliflozin over 52 weeks were exploratory endpoints in this extension to DEPICT-2. RESULTS: Of 813 participants randomized, 88.2% completed the study. From baseline to 52 weeks, dapagliflozin 5 and 10 mg were associated with reduction in HbA1c (difference [95% CI] vs. placebo: -0.20% [-0.34, -0.06] and -0.25% [-0.38, -0.11], respectively) and adjusted mean percentage change in body weight (difference [95% CI] vs. placebo: -4.42% [-5.19, -3.64] and -4.86% [-5.63, -4.08], respectively). Serious adverse events were reported in the dapagliflozin 5, 10 mg, and placebo groups (32 [11.8%], 19 [7.0%] and 16 [5.9%], respectively). The proportion of hypoglycaemic events was similar across groups; severe hypoglycaemia was uncommon. More participants with events adjudicated as definite diabetic ketoacidosis (DKA) were in the dapagliflozin 5 and 10 mg groups versus placebo (11 [4.1%], 10 [3.7%] and 1 [0.4%], respectively); the majority of events were mild or moderate in severity and all were resolved with treatment. CONCLUSIONS: Dapagliflozin led to long-term reductions in HbA1c and body weight in adults with T1D, but increased DKA risk compared with placebo. ispartof: DIABETES OBESITY & METABOLISM vol:22 issue:9 pages:1516-1526 ispartof: location:England status: published

Aim The DEPICT‐1 and ‐2 studies (NCT02268214, NCT02460978) evaluated the efficacy and safety of dapagliflozin in individuals with type 1 diabetes who were receiving intensive insulin therapy. The DEPICT‐1 and ‐2 studies (NCT02268214, NCT02460978) evaluated the efficacy and safety of dapagliflozin in individuals with type 1 diabetes. This post‐hoc study investigated the safety and efficacy of dapagliflozin in individuals with BMI ≥27 kg/m2 to assess if the benefit/risk ratio associated with dapagliflozin treatment can be further improved than that observed in the overall DEPICT population. Methods Changes in glycated haemoglobin (HbA1c) and body weight, percentage change in daily insulin dose and proportion of participants achieving HbA1c reduction ≥0.5% without severe hypoglycaemia were evaluated at weeks 24 and 52. Changes in mean interstitial glucose, mean amplitude of glycaemic excursions and time in target glycaemic range were evaluated at week 24. Safety was assessed until week 56. Results Week‐52 adjusted mean (SE) change from baseline for HbA1c was −0.26% (0.05) with dapagliflozin versus +0.08% (0.05) with placebo and for body weight was −2.74 kg (0.25) with dapagliflozin versus +0.81 kg (0.26) with placebo. Mean (SE) percentage change in daily insulin dose was −10.5% (1.23) with dapagliflozin versus −1.4% (1.36) with placebo. Time spent in target glycaemic range increased by 2.2 h/day versus placebo. Dapagliflozin was well tolerated, with fewer participants experiencing diabetic ketoacidosis (dapagliflozin, 1.7%; placebo, 1.0%) than dapagliflozin 5 mg receiving participants in the pooled DEPICT populations. Conclusions Compared with the pooled DEPICT population, the benefit/risk profile of adjunct dapagliflozin therapy was more favourable in individuals with type 1 diabetes with body mass index ≥27 kg/m2 because of the reduced risk of diabetic ketoacidosis in this population.
