Phase 3 trials have not compared oral semaglutide, a glucagon-like peptide 1 receptor agonist, with other classes of glucose-lowering therapy. OBJECTIVE To compare efficacy and assess long-term adverse event profiles of once-daily oral semaglutide vs sitagliptin, 100 mg added on to metformin with or without sulfonylurea, in patients with type 2 diabetes. DESIGN, SETTING, AND PARTICIPANTS Randomized, double-blind, double-dummy, parallel-group, phase 3a trial conducted at 206 sites in 14 countries over 78 weeks from February 2016 to March 2018. Of 2463 patients screened, 1864 adults with type 2 diabetes uncontrolled with metformin with or without sulfonylurea were randomized. INTERVENTIONS Patients were randomized to receive once-daily oral semaglutide, 3 mg (n = 466), 7 mg (n = 466), or 14 mg (n = 465), or sitagliptin, 100 mg (n = 467). Semaglutide was initiated at 3 mg/d and escalated every 4 weeks, first to 7 mg/d then to 14 mg/d, until the randomized dosage was achieved. MAIN OUTCOMES AND MEASURES The primary end point was change in glycated hemoglobin (HbA 1c), and the key secondary end point was change in body weight, both from baseline to week 26. Both were assessed at weeks 52 and 78 as additional secondary end points. End points were tested for noninferiority with respect to HbA 1c (noninferiority margin, 0.3%) prior to testing for superiority of HbA 1c and body weight. RESULTS Among 1864 patients randomized (mean age, 58 [SD, 10] years; mean baseline HbA 1c , 8.3% [SD, 0.9%]; mean body mass index, 32.5 [SD, 6.4]; n=879 [47.2%] women), 1758 (94.3%) completed the trial and 298 prematurely discontinued treatment (16.7% for semaglutide, 3 mg/d; 15.0% for semaglutide, 7 mg/d; 19.1% for semaglutide, 14 mg/d; and 13.1% for sitagliptin). Semaglutide, 7 and 14 mg/d, compared with sitagliptin, significantly reduced HbA 1c (differences,-0.3% [95% CI,-0.4% to-0.1%] and-0.5% [95% CI,-0.6% to-0.4%], respectively; P < .001 for both) and body weight (differences,-1.6 kg [95% CI,-2.0 to-1.1 kg] and-2.5 kg [95% CI,-3.0 to-2.0 kg], respectively; P < .001 for both) from baseline to week 26. Noninferiority of semaglutide, 3 mg/d, with respect to HbA 1c was not demonstrated. Week 78 reductions in both end points were statistically significantly greater with semaglutide, 14 mg/d, vs sitagliptin. CONCLUSIONS AND RELEVANCE Among adults with type 2 diabetes uncontrolled with metformin with or without sulfonylurea, oral semaglutide, 7 mg/d and 14 mg/d, compared with sitagliptin, resulted in significantly greater reductions in HbA 1c over 26 weeks, but there was no significant benefit with the 3-mg/d dosage. Further research is needed to assess effectiveness in a clinical setting.

Objectives To examine 25 year trends in first time hospitalisation for acute myocardial infarction in Denmark, subsequent short and long term mortality, and the prognostic impact of sex and comorbidity.Design Nationwide population based cohort study using medical registries. Setting All hospitals in Denmark.Subjects 234 331 patients with a first time hospitalisation for myocardial infarction from 1984 through 2008. Main outcome measuresStandardised incidence rate of myocardial infarction and 30 day and 31-365 day mortality by sex. Comorbidity categories were defined as normal, moderate, severe, and very severe according to the Charlson comorbidity index, and were compared by means of mortality rate ratios based on Cox regression.Results The standardised incidence rate per 100 000 people decreased in the 25 year period by 37% for women (from 209 to 131) and by 48% for men (from 410 to 213). The 30 day, 31-365 day, and one year mortality declined from 31.4%, 15.6%, and 42.1% in 1984-8 to 14.8%, 11.1%, and 24.2% in 2004-8, respectively. After adjustment for age at time of myocardial infarction, men and women had the same one year risk of dying. The mortality reduction was independent of comorbidity category. Comparing patients with very severe versus normal comorbidity during 2004-8, the mortality rate ratio, adjusted for age and sex, was 1.96 (95% CI 1.83 to 2.11) within 30 days and 3.89 (3.58 to 4.24) within 31-365 days. ConclusionsThe rate of first time hospitalisation for myocardial infarction and subsequent short term mortality both declined by nearly half between 1984 and 2008. The reduction in mortality occurred for all patients, independent of sex and comorbidity. However, comorbidity burden was a strong prognostic factor for short and long term mortality, while sex was not.

Bone metastasis and skeletal related events predict poor prognosis in men with prostate cancer.

Short- and long-term mortality improved considerably between 1994 and 2011 for all types of stroke. Short-term mortality improved regardless of comorbidity burden. However, comorbidity burden was a strong prognostic factor for both short- and long-term mortality.

Bone lesions as a consequence of bone metastases in breast cancer patients can increase risk for skeletal-related events (SREs) (i.e., radiation to the bone, a pathological or osteoporotic fracture event, hypercalcemia, spinal cord compression, or surgery to the bone). The mortality risk for breast cancer patients with SREs subsequent to bone metastases is unclear. We assessed this relationship in a large, population-based cohort of breast cancer patients in Denmark. We identified 35,912 newly diagnosed breast cancer patients from January 1, 1999 to December 31, 2007 in the Danish National Patient Registry (DNPR) and followed them through April 1, 2008. Information on stage and treatment was obtained from the Danish Cancer Registry. We used the Kaplan-Meier method to estimate survival, and Cox's regression analysis to estimate the mortality rate ratio (MRR) by the presence of bone metastases with and without SREs, adjusting for age and comorbidity. The 5-year survival was 75.8% for breast cancer patients without bone metastases, 8.3% for patients with bone metastases, and 2.5% for those with both bone metastases and SREs. The adjusted MRR was 10.5 [95% confidence interval (CI) 9.5-11.6] for breast cancer patients with bone metastases, and 14.4 (95% CI 13.1-15.8) for those with bone metastases and SREs, compared with breast cancer patients with no bone metastases but possibly other sites of metastases. A similar pattern persisted when analyses were stratified by stage or treatment. Breast cancer patients with bone metastases and SREs have a poor prognosis compared to those with and without bone metastases regardless of cancer treatment or stage of disease at diagnosis.

BackgroundBreast cancer (BrCa) is the most commonly diagnosed cancer among women in the industrialized world. More than half of women presenting with metastatic BrCa develop bone metastases. Bone metastases increase the risk of skeletal-related events (SREs), defined as pathological fractures, spinal cord compression, bone pain requiring palliative radiotherapy, and orthopaedic surgery. Both bone metastases and SREs are associated with unfavorable prognosis and greatly affect quality of life. Few epidemiological data exist on SREs after primary diagnosis of BrCa and subsequent bone metastasis. We therefore estimated the incidence of bone metastases and SREs in newly-diagnosed BrCa patients in Denmark from 1999 through 2007.MethodsWe estimated the overall and annual incidence of bone metastases and SREs in newly-diagnosed breast cancer patients in Denmark from January 1, 1999 to December 31, 2007 using the Danish National Patient Registry (DNPR), which covers all Danish hospitals. We estimated the cumulative incidence of bone metastases and SREs and associated 95% confidence intervals (CI) using the Kaplan-Meier method.ResultsOf the 35,912 BrCa patients, 178 (0.5%) presented with bone metastases at the time of primary breast cancer diagnosis, and of these, 77 (43.2%) developed an SRE during follow up. A total of 1,272 of 35,690 (3.6%) BrCa patients without bone metastases at diagnosis developed bone metastases during a median follow-up time of 3.4 years. Among these patients, 590 (46.4%) subsequently developed an SRE during a median follow-up time of 0.7 years. Incidence rates of bone metastases were highest the first year after the primary BrCa diagnosis, particularly among patients with advanced BrCa at diagnosis. Similarly, incidence rates of a first SRE was highest the first year after first diagnosis of a bone metastasis.ConclusionsThe high incidence of SREs following the first year after first diagnosis of a bone metastasis underscores the need for early BrCa detection and research on effective treatments to delay the onset of SREs.

Dietary agents are receiving much attention for the chemoprevention of cancer. While curcumin is known to influence several pathways and affect tumor growth in vivo, carnitin and its congeners play a variety of important metabolic functions: are involved in the oxydation of long‐chain fatty acids, regulate acyl‐CoA levels and influence protein activity and stability by modifying the extent of protein acetylation. In this study we evaluated the efficacy of carnitines in the prevention of cancer development using the 1,2,‐dimethylhydrazine (DMH)‐induced colon carcinogenesis model. We also assessed whether their combination was able to give rise to increased protection from cancer development. Mice treated with DMH were dosed orally with curcumin and/or carnitine and acylcarnitines for 20 weeks. At the end of the treatment colon samples were collected, and scored for multiple ACF and adenomas. We observed that carnitine and acyl‐carnitines had same, if not higher, efficacy than curcumin alone in inhibiting the formation of neoplastic lesions induced by DMH treatment. Interestingly, the combination of curcumin and acetyl‐L‐carnitine was able to fully inhibit the development of advanced adenoma lesions. Our data unveil the antitumor effects of carnitines and warrant additional studies to further support the adoption of carnitines as cancer chemopreventative agents. J. Cell.
