Evening chronotype has been associated with an increased risk of developing cardiometabolic diseases in obesity. Menopause is a lifestage associated with an increased risk of developing cardiometabolic diseases and a change in circadian rhythmicity compared to pre-menopause. However, the prevalence of chronotype categories in menopause and their role in determining menopause-related cardiometabolic risk, mostly in obesity, have not been investigated. Thus, we aimed to investigate the prevalence of chronotype categories in post-menopausal women with obesity and their role in menopause-related cardiometabolic risk. In this cross-sectional study we enrolled 49 pre-menopausal and 74 post-menopausal women with obesity. Anthropometric parameters, lifestyle habits, adherence to the Mediterranean Diet (MD), sleep quality, chronotype and the presence of type 2 diabetes mellitus (T2DM) and cardiovascular diseases (CVD) were studied. No significance differences were detected in terms of lifestyle and adherence to the MD between pre- and post-menopausal women. Chronotype was classified as morning in 66 (53.6\%), evening in 20 (16.3\%) and intermediate in 37 (30.1\%) women. In addition, pre-menopausal women with obesity showed a significantly higher chance to have an intermediate chronotype (OR = 2.21, 95\% CI 1.28-3.83; p = 0.004), whereas post-menopausal women with obesity showed a trend to have a higher morning chronotype (OR = 1.42, 95\% CI 0.98-2.06; p = 0.051), although this did not reach statistical significance. No significant differences were detected in terms of prevalence of evening chronotype between the two groups. However, the evening chronotype had a significantly higher risk to have T2DM compared to the morning (OR = 17.29, 95\% CI 2.40-124.27; p = 0.005) and intermediate chronotypes (OR = 30.86, 95\% CI 2.05-464.32; p = 0.013) in both pre- and post-menopausal women with obesity. In conclusion, the intermediate chronotype was significantly more prevalent in pre-menopausal women with obesity compared to post-menopausal women. Evening chronotype was associated to T2DM in both pre- and post-menopause. These results support the importance of including the assessment of chronotype in the management of women with obesity in post-menopause.}, language = {en} } @article{GutierrezGiraldoDavilaCombarizaetal.2020, author = {Guti{\´e}rrez, Gustavo and Giraldo-D{\´a}vila, Deisy and Combariza, Marianny Y. and Holzgrabe, Ulrike and Tabares-Guevara, Jorge Humberto and Ram{\´i}rez-Pineda, Jos{\´e} Robinson and Ac{\´i}n, Sergio and Mu{\~n}oz, Diana Lorena and Montoya, Guillermo and Balcazar, Norman}, title = {Serjanic acid improves immunometabolic markers in a diet-induced obesity mouse model}, series = {Molecules}, volume = {25}, journal = {Molecules}, number = {7}, issn = {1420-3049}, doi = {10.3390/molecules25071486}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-203253}, year = {2020}, abstract = {Plant extracts from Cecropia genus have been used by Latin-American traditional medicine to treat metabolic disorders and diabetes.

While best standards of care, including high-dose statins, can ameliorate the risk of vascular complications, patients remain at high risk of cardiovascular events. The Residual Risk Reduction Initiative (R(3)i) has previously highlighted atherogenic dyslipidaemia, defined as the imbalance between proatherogenic triglyceride-rich apolipoprotein B-containing-lipoproteins and antiatherogenic apolipoprotein A-I-lipoproteins (as in high-density lipoprotein, HDL), as an important modifiable contributor to lipid-related residual cardiovascular risk, especially in insulin-resistant conditions. As part of its mission to improve awareness and clinical management of atherogenic dyslipidaemia, the R(3)i has identified three key priorities for action: i) to improve recognition of atherogenic dyslipidaemia in patients at high cardiometabolic risk with or without diabetes; ii) to improve implementation and adherence to guideline-based therapies; and iii) to improve therapeutic strategies for managing atherogenic dyslipidaemia. The R(3)i believes that monitoring of non-HDL cholesterol provides a simple, practical tool for treatment decisions regarding the management of lipid-related residual cardiovascular risk. Addition of a fibrate, niacin (North and South America), omega-3 fatty acids or ezetimibe are all options for combination with a statin to further reduce non-HDL cholesterol, although lacking in hard evidence for cardiovascular outcome benefits. Several emerging treatments may offer promise. These include the next generation peroxisome proliferator-activated receptor alpha agonists, cholesteryl ester transfer protein inhibitors and monoclonal antibody therapy targeting proprotein convertase subtilisin/kexin type 9. However, long-term outcomes and safety data are clearly needed. In conclusion, the R(3)i believes that ongoing trials with these novel treatments may help to define the optimal management of atherogenic dyslipidaemia to reduce the clinical and socioeconomic burden of residual cardiovascular risk.}, language = {en} } @article{ZinmanInzucchiLachinetal.2014, author = {Zinman, Bernard and Inzucchi, Silvio E. and Lachin, John M. and Wanner, Christoph and Ferrari, Roberto and Fitchett, David and Bluhmki, Erich and Hantel, Stefan and Kempthorne-Rawson, Joan and Newman, Jennifer and Johansen, Odd Erik and Woerle, Hans-Juergen and Broedl, Uli C.}, title = {Rationale, design, and baseline characteristics of a randomized, placebo-controlled cardiovascular outcome trial of empagliflozin (EMPA-REG OUTCOME (TM))}, series = {Cardiovascular Diabetology}, volume = {13}, journal = {Cardiovascular Diabetology}, number = {102}, issn = {1475-2840}, doi = {10.1186/1475-2840-13-102}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-116036}, year = {2014}, abstract = {Background: Evidence concerning the importance of glucose lowering in the prevention of cardiovascular (CV) outcomes remains controversial. Given the multi-faceted pathogenesis of atherosclerosis in diabetes, it is likely that any intervention to mitigate this risk must address CV risk factors beyond glycemia alone. The SGLT-2 inhibitor empagliflozin improves glucose control, body weight and blood pressure when used as monotherapy or add-on to other antihyperglycemic agents in patients with type 2 diabetes. The aim of the ongoing EMPA-REG OUTCOME (TM) trial is to determine the long-term CV safety of empagliflozin, as well as investigating potential benefits on macro-/microvascular outcomes. Methods: Patients who were drug naive (HbA(1c) >= 7.0\% and <= 9.0\%), or on background glucose-lowering therapy (HbA(1c) >= 7.0\% and <= 10.0\%), and were at high risk of CV events, were randomized (1:1:1) and treated with empagliflozin 10 mg, empagliflozin 25 mg, or placebo (double blind, double dummy) superimposed upon the standard of care. The primary outcome is time to first occurrence of CV death, non-fatal myocardial infarction, or non-fatal stroke. CV events will be prospectively adjudicated by an independent Clinical Events Committee. The trial will continue until >= 691 confirmed primary outcome events have occurred, providing a power of 90\% to yield an upper limit of the adjusted 95\% CI for a hazard ratio of <1.3 with a one-sided a of 0.025, assuming equal risks between placebo and empagliflozin (both doses pooled). Hierarchical testing for superiority will follow for the primary outcome and key secondary outcomes (time to first occurrence of CV death, non-fatal myocardial infarction, non-fatal stroke or hospitalization for unstable angina pectoris) where non-inferiority is achieved. Results: Between Sept 2010 and April 2013, 592 clinical sites randomized and treated 7034 patients (41\% from Europe, 20\% from North America, and 19\% from Asia). At baseline, the mean age was 63 +/- 9 years, BMI 30.6 +/- 5.3 kg/m(2), HbA1c 8.1 +/- 0.8\%, and eGFR 74 +/- 21 ml/min/1.73 m(2). The study is expected to report in 2015. Discussion: EMPA REG OUTCOME (TM) will determine the CV safety of empagliflozin in a cohort of patients with type 2 diabetes and high CV risk, with the potential to show cardioprotection.}, language = {en} } @article{SchneiderSchneiderScharnagletal.2013, author = {Schneider, Andreas and Schneider, Markus P. and Scharnagl, Hubert and Jardine, Alan G. and Wanner, Christoph and Drechsler, Christiane}, title = {Predicting erythropoietin resistance in hemodialysis patients with type 2 diabetes}, series = {BMC Nephrology}, volume = {14}, journal = {BMC Nephrology}, number = {67}, doi = {10.1186/1471-2369-14-67}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-128695}, year = {2013}, abstract = {Background: Resistance to ESAs (erythropoietin stimulating agents) is highly prevalent in hemodialysis patients with diabetes and associated with an increased mortality. The aim of this study was to identify predictors for ESA resistance and to develop a prediction model for the risk stratification in these patients. Methods: A post-hoc analysis was conducted of the 4D study, including 1015 patients with type 2 diabetes undergoing hemodialysis. Determinants of ESA resistance were identified by univariate logistic regression analyses. Subsequently, multivariate models were performed with stepwise inclusion of significant predictors from clinical parameters, routine laboratory and specific biomarkers. Results: In the model restricted to clinical parameters, male sex, shorter dialysis vintage, lower BMI, history of CHF, use of ACE-inhibitors and a higher heart rate were identified as independent predictors of ESA resistance. In regard to routine laboratory markers, lower albumin, lower iron saturation, higher creatinine and higher potassium levels were independently associated with ESA resistance. With respect to specific biomarkers, higher ADMA and CRP levels as well as lower Osteocalcin levels were predictors of ESA resistance. Conclusions: Easily obtainable clinical parameters and routine laboratory parameters can predict ESA resistance in diabetic hemodialysis patients with good discrimination. Specific biomarkers did not meaningfully further improve the risk prediction of ESA resistance. Routinely assessed data can be used in clinical practice to stratify patients according to the risk of ESA resistance, which may help to assign appropriate treatment strategies.}, language = {en} } @article{GybergDeBacquerDeBackeretal.2015, author = {Gyberg, Viveca and De Bacquer, Dirk and De Backer, Guy and Jennings, Catriona and Kotseva, Kornelia and Mellbin, Linda and Schnell, Oliver and Tuomilehto, Jaakko and Wood, David and Ryden, Lars and Amouyel, Philippe and Bruthans, Jan and Conde, Almudena Castro and Cifkova, Renata and Deckers, Jaap W. and De Sutter, Johan and Dilic, Mirza and Dolzhenko, Maryna and Erglis, Andrejs and Fras, Zlatko and Gaita, Dan and Gotcheva, Nina and Goudevenos, John and Heuschmann, Peter and Laucevicius, Aleksandras and Lehto, Seppo and Lovic, Dragan and Milicic, Davor and Moore, David and Nicolaides, Evagoras and Oganov, Raphae and Pajak, Andrzej and Pogosova, Nana and Reiner, Zeljko and Stagmo, Martin and St{\"o}rk, Stefan and Tokg{\"o}zoglu, Lale and Vulic, Dusko}, title = {Patients with coronary artery disease and diabetes need improved management: a report from the EUROASPIRE IV survey: a registry from the EuroObservational Research Programme of the European Society of Cardiology}, series = {Cardiovascular Diabetology}, volume = {14}, journal = {Cardiovascular Diabetology}, number = {133}, doi = {10.1186/s12933-015-0296-y}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-141358}, year = {2015}, abstract = {Background: In order to influence every day clinical practice professional organisations issue management guidelines. Cross-sectional surveys are used to evaluate the implementation of such guidelines. The present survey investigated screening for glucose perturbations in people with coronary artery disease and compared patients with known and newly detected type 2 diabetes with those without diabetes in terms of their life-style and pharmacological risk factor management in relation to contemporary European guidelines. Methods: A total of 6187 patients (18-80 years) with coronary artery disease and known glycaemic status based on a self reported history of diabetes (previously known diabetes) or the results of an oral glucose tolerance test and HbA1c (no diabetes or newly diagnosed diabetes) were investigated in EUROASPIRE IV including patients in 24 European countries 2012-2013. The patients were interviewed and investigated in order to enable a comparison between their actual risk factor control with that recommended in current European management guidelines and the outcome in previously conducted surveys. Results: A total of 2846 (46 \%) patients had no diabetes, 1158 (19 \%) newly diagnosed diabetes and 2183 (35 \%) previously known diabetes. The combined use of all four cardioprotective drugs in these groups was 53, 55 and 60 \%, respectively. A blood pressure target of <140/90 mmHg was achieved in 68, 61, 54 \% and a LDL-cholesterol target of <1.8 mmol/L in 16, 18 and 28 \%. Patients with newly diagnosed and previously known diabetes reached an HbA1c <7.0 \% (53 mmol/mol) in 95 and 53 \% and 11 \% of those with previously known diabetes had an HbA1c >9.0 \% (>75 mmol/mol). Of the patients with diabetes 69 \% reported on low physical activity. The proportion of patients participating in cardiac rehabilitation programmes was low (approximate to 40 \%) and only 27 \% of those with diabetes had attended diabetes schools. Compared with data from previous surveys the use of cardioprotective drugs had increased and more patients were achieving the risk factor treatment targets.

At the onset of kidney disease, therapies that inhibit components of the renin angiotensin system (RAS) are also indicated, but these approaches are not wholly effective. Here, we show that once daily administration of the novel glucose lowering agent, empagliflozin, an SGLT2 inhibitor which targets the kidney to block glucose reabsorption, has the potential to improve kidney disease in type 2 diabetes. In male db/db mice, a 10-week treatment with empagliflozin attenuated the diabetes-induced upregulation of profibrotic gene markers, fibronectin and transforming-growth-factor-beta. Other molecular (collagen IV and connective tissue growth factor) and histological (tubulointerstitial total collagen and glomerular collagen IV accumulation) benefits were seen upon dual therapy with metformin. Albuminuria, urinary markers of tubule damage (kidney injury molecule-1, KIM-1 and neutrophil gelatinase-associated lipocalin, NGAL), kidney growth, and glomerulosclerosis, however, were not improved with empagliflozin or metformin, and plasma and intra-renal renin activity was enhanced with empagliflozin. In this model, blood glucose lowering with empagliflozin attenuated some molecular and histological markers of fibrosis but, as per treatment with metformin, did not provide complete renoprotection.

Consistently, application of ileal content from RYGB-treated compared with sham-operated rats onto Caco-2 cell monolayers compromised barrier function and decreased expression of the barrier-stabilizing proteins claudin-4 and desmoglein-2.

It may be explained by reduced erythropoietin (EPO) synthesis, but recent data suggest that EPO-resistance and diminished iron availability due to inflammation contribute significantly. In this cohort study, we evaluated the impact of hepcidin-25—the key hormone of iron-metabolism—on clinical outcomes in diabetic patients with CKD along with endogenous EPO levels. Methods 249 diabetic patients with CKD of any stage, excluding end-stage renal disease (ESRD), were enrolled (2003-2005), if they were not on EPO-stimulating agent and iron therapy. Hepcidin-25 levels were measured by radioimmunoassay. The association of hepcidin-25 at baseline with clinical variables was investigated using linear regression models. All-cause mortality and a composite endpoint of CKD progression (ESRD or doubling of serum creatinine) were analyzed by Cox proportional hazards models. Results Patients (age 67 yrs, 53\% male, GFR 51 ml/min, hemoglobin 131 g/L, EPO 13.5 U/L, hepcidin-25 62.0 ng/ml) were followed for a median time of 4.2 yrs. Forty-nine patients died (19.7\%) and forty (16.1\%) patients reached the composite endpoint. Elevated hepcidin levels were independently associated with higher ferritin-levels, lower EPO-levels and impaired kidney function (all p<0.05). Hepcidin was related to mortality, along with its interaction with EPO, older age, greater proteinuria and elevated CRP (all p<0.05). Hepcidin was also predictive for progression of CKD, aside from baseline GFR, proteinuria, low albumin- and hemoglobin-levels and a history of CVD (all p<0.05). Conclusions We found hepcidin-25 to be associated with EPO and impaired kidney function in diabetic CKD. Elevated hepcidin-25 and EPO-levels were independent predictors of mortality, while hepcidin-25 was also predictive for progression of CKD. Both hepcidin-25 and EPO may represent important prognostic factors of clinical outcome and have the potential to further define "high risk" populations in CKD.}, language = {en} }
