We aimed to explore whether a higher serum uric acid level was associated with low SMM in the Chinese population.\u0000\u0000\u0000METHODS\u0000We performed a cross-sectional analysis of 6595 subjects aged 45 years or older. They were tested for fasting blood glucose, total cholesterol, triglycerides, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, uric acid, blood urea nitrogen, creatinine, and estimated glomerular filtration rate. SMM was accessed by dual-energy x-ray absorptiometry using two approaches: weight-adjusted appendicular skeletal muscle mass (ASM)% and ASM/BMI (body mass index (kg/m2)). Low SMM was defined as a cut-off point of ASM/BMI<0.789 for men and<0.512 for women.\u0000\u0000\u0000RESULTS\u0000Compared with their normal group, patients with hyperuricemia had lower ASM% (29.33±2.33 vs 30.03±2.34 for males and 24.71±1.99 vs 25.19±2.07 for females, P<0.01) and ASM/BMI (0.83±0.10 vs 0.85±0.10 for male and 0.60±0.07 vs 0.62±0.07 for female), with a higher prevalence of the associated low SMM in both sexes (35.2 vs 26.5% for male and 10.5 vs 5.9% for female, P<0.01). Pearson analysis showed that ASM% and ASM/BMI were negatively correlated with SUA (male: ASM/BMI, r=-0.097, ASM%, r=-0.146; female: ASM/BMI, r=-0.151, ASM%, r=-0.157; all P<0.001). Logistic regression analysis showed a positive association of hyperuricemia with adjusted risk of low SMM association.\u0000\u0000\u0000CONCLUSIONS\u0000In a middle-aged and elderly Chinese population, hyperuricemia is independently and positively associated with low SMM and can vary by age and gender.","PeriodicalId":94001,"journal":{"name":"Experimental and clinical endocrinology & diabetes : official journal, German Society of Endocrinology [and] German Diabetes Association","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84921055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Is the size of insulinoma predictive for its endocrine behavior? An endoscopic ultrasound study.","authors":"Jan Adelmeyer, Franziska Göbel, P. Kann","doi":"10.1055/a-1840-7492","DOIUrl":"https://doi.org/10.1055/a-1840-7492","url":null,"abstract":"OBJECTIVE\u0000The insulinoma is a rare tumor of the pancreas, that can lead to spontaneous hypoglycemia due to an excessive insulin secretion. The 72-hour fast is the gold standard for finding the correct diagnosis. Endoscopic ultrasound (EUS) is an established examination method to identify the suspicious lesion. Previous studies correlate the measured size of insulinoma and their endocrine behavior. This study was designed to find a relation between these variables.\u0000\u0000\u0000METHODS\u0000We took the data of patients which had a histological confirmed insulinoma after receiving an endoscopic ultrasound in our department. Size and echogenicity were correlated with the endpoint of the 72-hour fast and hormone levels.\u0000\u0000\u0000RESULTS\u0000A total of 45 patients were identified. Most insulinoma were small with a volume of < 2cm3 (median 1.15cm3). There was no correlation between the duration of fasting, hormone levels and the size of the insulinoma. In addition, in a subgroup analysis, no connection could be established between the size of the insulinoma and the amount of insulin that was released after oral glucose exposure. We found out that homogeneous tumors were significantly smaller and had a lower Ki-67 index. Furthermore, there was a tendency towards a shorter period of duration for the 72-hour fast for the small tumors.\u0000\u0000\u0000DISCUSSION\u0000This data suggests that the measured size of insulinoma by EUS is not related to the time until termination of the 72-hour fast and measured hormone levels. The echogenicity seems more important, showing that homogenous tumors are an indicator for a higher differentiation, which can result in a shorter duration of fasting period. The differences in the secretion behavior of the insulinomas could complicate the correlation of size and duration of the 72-hour fast.","PeriodicalId":94001,"journal":{"name":"Experimental and clinical endocrinology & diabetes : official journal, German Society of Endocrinology [and] German Diabetes Association","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89967465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jansen","doi":"10.1055/a-1816-8203","DOIUrl":"https://doi.org/10.1055/a-1816-8203","url":null,"abstract":"The stereotypic and oversimplified relationship between female sex hormones and undesirable behavior dates to the earliest days of human society, as already the ancient Greek word for the uterus, \"hystera\" indicated an aversive connection. Remaining and evolving throughout the centuries, transcending across cultures and various aspects of everyday life, its perception was only recently reframed. Contemporarily, the complex interaction of hormonal phases (i. e., the menstrual cycle), hormonal medication (i. e., oral contraceptives), women's psychological well-being, and behavior is the subject of multifaceted and more reflected discussions. A driving force of this ongoing paradigm shift was the introduction of this highly interesting and important topic into the realm of scientific research. This refers to neuroscientific research as it enables a multimodal approach combining aspects of physiology, medicine, and psychology. Here a growing body of literature points towards significant alterations of both brain function, such as lateralization of cognitive functions, and structure, such as gray matter concentrations, due to fluctuations and changes in hormonal levels. This especially concerns female sex hormones. However, the more research is conducted within this field, the less reliable these observations and derived insights appear. This may be due to two particular factors: measurement inconsistencies and diverse hormonal phases accompanied by interindividual differences. The first factor refers to the prominent unreliability of one of the primarily utilized neuroscientific research instruments: functional magnetic resonance imaging (fMRI). This unreliability is seemingly present in paradigms and analyses, and their interplay, and is additionally affected by the second factor. In more detail, hormonal phases and levels further influence neuroscientific results obtained through fMRI as outcomes vary drastically across different cycle phases and medication. This resulting vast uncertainty thus tremendously hinders the further advancement of our understanding of how female sex hormones might alter brain structure and function and, ultimately, behavior.This review summarizes parts of the current state of research and outlines the essential requirements to further investigate and understand the female brain's underlying physiological and anatomical features.","PeriodicalId":94001,"journal":{"name":"Experimental and clinical endocrinology & diabetes : official journal, German Society of Endocrinology [and] German Diabetes Association","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74534516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to drug therapy, the therapy behaviour of the person with diabetes plays a significant role in the prognosis of the disease. In diabetes therapy, it is therefore important to define therapy goals together with the person with diabetes, taking into account a multitude of biological, somatic, social and behavioural factors, and to support those affected as best as possible in implementing therapy goals into their personal living environment and their self-management. The most important superordinate therapy goals for diabetes are described in the evidence-based guidelines for type 1 and type 2 diabetes [1, 2], as well as in the Disease Management Program (DMP) requirements guideline (DMP-A-RL) [3]. ▪ Maintaining or improving the quality of life limited by diabetes: For people with diabetes, maintaining the quality of life is the most important goal of diabetes therapy [4]. This means remaining as physically and psychologically healthy as possible despite and with diabetes, being able to realise one’s own life goals and being socially integrated – without being limited in areas of life that are important for people, such as family/relationship, job, interests, leisure time, etc. Study results show relatively consistently that these goals, which are important for people with diabetes, have not yet been achieved worldwide [5, 6]. ▪ Preventing symptoms of the disease: Elevated, decreased or even highly-fluctuating glucose levels (increased glucose variability) can lead to symptoms such as an increased urge to urinate (polyuria), a strong feeling of thirst (polydipsia), fatigue, weakness and tiredness. Symptoms that should be avoided during therapy also include dry or itchy skin, neuropathic symptoms and fluctuations in lens refractive power due to osmotic effects of increased glucose levels. ▪ Preventing acute complications: It is important to prevent side effects of antihyperglycaemic therapy, in particular hypoglycaemia – especially severe hypoglycaemia in which the affected person is dependent on external help (e. g., by relatives or medical staff). As well, it is important to prevent severe hyperglycaemic metabolic derailments (e. g., diabetic ketoacidosis) because of the associated burdens and dangers for the person with diabetes, as well as the associated health risks, which can be lethal in some cases.

Their transdifferentiation can be achieved by triggering epigenetic remodeling through e. g. post-translational modification of histones. Valproic acid, a branched-chain saturated fatty acid with histone deacetylase inhibitor activity, was linked to the expression of key transcription factors of pancreatic lineage in epithelial cells and insulin transcription. However, the potential of valproic acid to cause cellular reprogramming is not fully understood. To shed further light on it we employed next-generation RNA sequencing, real-time PCR, and protein analyses by ELISA and western blot, to assess the impact of valproic acid on transcriptome and function of Panc-1-cells. Our results indicate that valproic acid has a significant impact on the cell cycle, cell adhesion, histone H3 acetylation, and metabolic pathways as well as the initiation of epithelial-mesenchymal transition through acetylation of histone H3 resulting in α-cell-like characteristics. We conclude that human epithelial pancreatic cells can be transdifferentiated into cells with endocrine properties through epigenetic regulation by valproic acid favoring an α-cell-like phenotype.","PeriodicalId":94001,"journal":{"name":"Experimental and clinical endocrinology & diabetes : official journal, German Society of Endocrinology [and] German Diabetes Association","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87102633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
