Metabolic control of thirty-seven patients aged between 1 and 18 years, with coexisting T1D and CD were evaluated. The control group includes 37 patients affected only by diabetes. All data relating to the metabolic control of all patients were acquired through examination of medical records and CMG reports available on dedicated online platforms. Glucose variability was expressed as Coefficient of Variation (CV) and Standard Deviation of blood glucose values (SD). The formula used for CV computation is: CV (%) = 100 × SD (daily glycemia)/Mean (daily glycemia). Patients with T1D and CD showed a significant reduction in rapid pre-prandial insulin. The same reduction was present if we consider only patients using CGM. In patients without CGM, there was no difference in the doses of basal, pre-prandial and total insulin. Indicators of metabolic control were overlapping between the two groups in patients who used CGM. On the contrary, diabetic and coeliac patients without CGM had increased levels of glycaemic variability indicators and HbA1c. Finally, the percentage of target glycaemic values and >250 mg/dL glycaemic values were significantly decreased and increased, respectively in T1D and CD patients without CGM. With this study we wanted to demonstrate if CGM could improve metabolic control of patients with coexisting T1D and CD. Our data show a worse metabolic control in patients with T1D and CD who did not use CGM. Instead, patients who use CGM, regardless of the concomitant CD, manage to achieve the same glycaemic targets through an adjustment of titration of pre-prandial insulin doses.","PeriodicalId":72908,"journal":{"name":"Endocrines","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44528387","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}

Testosterone plays critical roles in both reproductive and metabolic functions and therefore is essential for male health. Steroidogenesis must be properly regulated since dysregulated hormone production can lead to infertility and metabolic disorders. Leydig cell steroidogenesis relies on the coordinated interaction of various factors, such as hormones and signaling molecules. While luteinizing hormone (LH) is the main regulator of Leydig cell steroidogenesis, other molecules, including growth hormones (GH), prolactin, growth factors (insulin, IGF, FGF, EGF), and osteocalcin, have also been implicated in the stimulation of steroidogenesis. This review provides a comprehensive summary of the mechanisms and signaling pathways employed by LH and other molecules in the stimulation of Leydig cell steroidogenesis, providing valuable insights into the complex regulation of male reproductive and metabolic health.","PeriodicalId":72908,"journal":{"name":"Endocrines","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48016600","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}

However, the precise contribution of these factors to thyroid disease remains a subject of controversy. Consequently, there is a pressing need to gain a comprehensive understanding of the related associations in order to potentially mitigate the associated morbidity and mortality rates. Methods: This study employed association rule mining techniques to reveal hidden correlations among complex and diverse epidemiological connections pertaining to thyroid disease associations. We proposed a framework which incorporates text mining and association rule mining algorithms with exceptionality measurement to simultaneously identify common and exception risk factors correlated with the disease through real-life digital health records. Two distinctive datasets were analyzed through two algorithms, and mutual factors were retained for interpretation. Results: The results confirmed that age, gender, and history of thyroid disease are risk factors positively related to subsequent thyroid cancer. Furthermore, it was observed that the absence of underlying chronic disease conditions, such as diabetes, hypertension, or obesity, are associated with reduced likelihood of being diagnosed with thyroid cancer. Conclusions: Collectively, the proposed framework demonstrates its sound feasibility and should be further recommended for different disease in-depth knowledge discovery.","PeriodicalId":72908,"journal":{"name":"Endocrines","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42983022","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}

The Renin–Angiotensin System Study (RASS) tested whether a 5-year renin–angiotensin system (RAS) blockade with enalapril or losartan versus placebo slowed progression of early diabetic nephropathy lesions in 285 normoalbuminuric, normotensive, normal/high GFR patients with type 1 diabetes. RASS found no benefit to the RAS blockade on diabetic glomerular lesions but observed an unexpected 50% increase in the fractional volume of the renal cortex which is the interstitium. The effects of the RAS blockade on individual interstitial components––striated collagen, interstitial cells, and peritubular capillaries––were not assessed. We evaluated by electron microscopy changes in fractional volume of each component in seven patients from each group between baseline and five years. At baseline, 49% of the interstitium was collagen, 12% cells, 26% peritubular capillaries, 7% space, and 2% artifact. There was no overall change in the interstitial composition during the RASS. There were no statistically significant effects of treatment group on any interstitial components. Renal volume remained stable in all groups. The RAS blockade affected neither the approximately 50% increase in interstitium fractional volume per cortex nor the parallel increase in all interstitial components that occurred over the five years of the RASS.","PeriodicalId":72908,"journal":{"name":"Endocrines","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44503566","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}

It is a devastating diagnosis that can affect the adolescent’s view of her femininity, sexuality, fertility and self-image. A normal menstrual cycle can occur only in the presence of: a properly functioning hypothalamus–pituitary axis, well-developed and active ovaries, outflow tract without abnormalities. Any dysfunction in any of these players can result in amenorrhea. PA evaluation includes the patient’s medical history, physical examination, pelvic ultrasonography and initial hormone evaluation, limited to the serum-follicle-stimulating hormone (FSH) and luteinizing hormone, testosterone and prolactin. A karyotype should be obtained in all adolescents with high FSH serum levels. The main causes of PA, whether or not accompanied by secondary sexual characteristics, include endocrine defects of the hypothalamus–pituitary–ovarian axis, genetic defects of the ovary, metabolic diseases, autoimmune diseases, infections, iatrogenic causes (radiotherapy, chemotherapy), environmental factors and Müllerian tract defects. PA management depends on the underlying causes. Estrogen replacement therapy at puberty has mainly been based on personal experience. PA can be due to endocrine, genetic, metabolic, anatomical and environmental disorders that may have severe implications on reproductive health later in life. In some complex cases, a multidisciplinary team best manages the adolescent, including a pediatrician endocrinologist, gynecologist, geneticist, surgeon, radiologist, and psychologist.","PeriodicalId":72908,"journal":{"name":"Endocrines","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41721040","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}

Patients with diabetes have a four-times-greater risk of hospitalization with longer hospital stays and a greater chance of readmission compared to patients without diabetes. Spending on diabetes care as a proportion of global GDP is also projected to increase from 1.8% in 2015 to 2.2% in 2030. The largest component of this medical expenditure is inpatient care in hospitalized patients, accounting for USD 69.7 billion of the total medical cost. Hospitalized patients can develop hyperglycemia without a history of pre-existing diabetes. It has been shown that hyperglycemia in patients without a history of diabetes is also associated with poor hospital outcome. In this review, we discuss the adverse effects of hyperglycemia and hypoglycemia on hospital outcomes; we review recent glycemic targets, recent guidelines’ recommendations, and landmark trials with a brief review on discharge planning, updates on hyperglycemic emergencies, and the use of newer technologies in hospitalized patients such as continuous glucose monitoring devices.","PeriodicalId":72908,"journal":{"name":"Endocrines","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42818557","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}

Studies published in English with measured sleep characteristics were included. Studies focused on participants with severe psychiatric illness, night shift workers, or with a pharmacologic sleep treatment focus were excluded. The risk for bias was assessed using the NHLBI 2021 Quality Assessment Tool. Two reviewers independently synthesized the results before reaching a consensus. Out of 340 studies screened, 35 studies were included. There were 631,756 participants with an average age of 44.3 combined (SD = 16.5) (53% female and 22% Black). Disparities in sleep health characteristics and cardiometabolic health among African American adults were found. Markers of poor cardiometabolic health were associated with disordered sleep. While the studies in this review captured key factors, the study measurement methods were inconsistent, and African Caribbean Americans were underrepresented. The studies demonstrated the intersectionality of poor sleep characteristics, cardiometabolic risk factors, and racial/ethnic groupings.

Glucagon secretion exhibits heterogenous patterns in individuals and across glucose tolerance diagnoses. Characterization of the range of glucagon secretion patterns can help clinicians personalize diabetes care based on glucagon characteristics in addition to glucose and insulin profiles. A total of 102 subjects with normal glucose tolerance, impaired glucose tolerance, and T2D had their glucagon profiles recorded in response to an oral glucose tolerance test. Shapelet analysis was used to identify the most descriptive patterns of early glucagon secretion, and spectral biclustering was employed to identify biclusters of associated subjects and shapelets. The dynamics of glucose, insulin, and glucagon secretion in each cluster were evaluated to identify overall patterns, and the characteristics of the subjects in each cluster were compared. Three clusters were chosen to represent the glucagon patterns. Membership in these three clusters was interpreted based on the presence or lack of extrema in the first 30 min after oral carbohydrate intake. Cluster 1 (n = 23) had a minimum at 30 min and only negative trends. Cluster 2 had a minimum at 10 min and a maximum at 20 min (n = 25). Cluster 3 (n = 40) had a maximum at 10 min and a minimum at 20 min. Subjects in cluster 1 had the lowest average fasting plasma glucose (90.17 mg/dL) and average age (41.39 years) and the highest HOMA-beta score (87.5%), while subjects in cluster 2 had the highest average fasting plasma glucose (102.56 mg/dL) and average age (53.16 years) and the lowest HOMA-beta score (55.77%). Characterization of glucagon dynamics, in addition to glucose and insulin, can aid in personalized treatment approaches and provide greater insight about the underlying dysfunction in glucose regulation.","PeriodicalId":72908,"journal":{"name":"Endocrines","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47129082","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}

Hypothalamic neuropeptides act as neurotransmitters and hormones to regulate the physiology of food intake, digestion, and metabolism, having a direct or indirect impact on the liver. Investigations on liver pathologies found that dysfunctions of neuropeptides and their receptors are associated with liver disorders such as non-alcoholic fatty liver disease, steatohepatitis, cholestasis, cirrhosis, and liver cancer. In this article, we reviewed neuropeptides that regulate energy homeostasis and lipid and glucose metabolism in the liver and are associated with liver injuries. Firstly, peptides involved in regulatory processes in the brain and liver, such as neuropeptide Y, agouti-related protein, and the galanin family, are related to obesity and its comorbidities, including type 2 diabetes and metabolic syndrome, are presented. Secondly, a comprehensive review of neuropeptides such as secretin, vasoactive intestinal peptide, substance P, and somatostatin, which are involved in liver injuries unrelated to obesity; i.e., cholestasis-induced biliary hyperplasia, cirrhosis, hepatocellular carcinoma, and cholangiocarcinoma, is also presented. The cellular and molecular mechanisms underlining liver injuries related to the dysfunction of these neuropeptides and receptors are also described.","PeriodicalId":72908,"journal":{"name":"Endocrines","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43666221","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}

Hypoxia, a main pathological feature of visceral fat in obese individuals, has been shown to affect the secretome of murine 3T3-L1 adipose cells, causing the upregulation of prothymosin-alpha (ProT-α), which is a protein with immunomodulatory functions that was originally found in the thymus. The aim of this case–control observational study was to measure the circulating levels of ProT-α in obese and lean individuals and determine whether such levels are correlated with inflammatory and metabolic parameters. Methods: Sixty-one obese patients (BMI ≥ 30 Kg/m2) and fifty-one age-matched, lean controls (BMI 18.5–24.9 Kg/m2) were recruited in the Endocrinology Unit (“Mater-Domini”) of the University Hospital of Catanzaro, Italy. The exclusion criteria included affliction with acute and systemic inflammatory states (i.e., leukocytosis), recent infectious diseases or vaccinations, obesity complications (i.e., type 2 diabetes mellitus and cardiovascular diseases), hepatic or renal failure, pregnancy and lactation, cancer, use of drugs or alcohol, and smoking. Apart from routine biochemical determinations, serum samples were screened for the presence of ProT-α using an ELISA method and for the presence of a panel of inflammatory cytokines and growth factors via a multiparametric chemiluminescence micro-array. Results: Between the age-matched groups, no statistically significant differences were shown in relation to fasting glucose, HbA1c, liver function tests, lipid profiles, circulating interleukins (IL)-1α, -1β, -2, -4, -8, and -10, MCP-1, TNF-α, VEGF and EGF. Instead, significantly higher median levels were observed in obese patients vs. lean controls with respect to fasting insulin levels (p < 0.001), a classic insulin resistance marker, and IL-6 (p = 0.004). In addition, ProT-α levels were significantly and considerably higher in obese patients compared to lean controls (median ProT-α, 600.0 vs. 411.5 pg/mL, p = 0.004) and showed a moderate to strong positive relationship with fasting insulin levels and selected cytokines (i.e., TNF-α and IL-8). Conclusions: An increase in circulating levels of ProT-α is linked with obesity and can be detected before any clinical cardiometabolic complications develop. ProT-α may represent a novel and sensitive biomarker for inflammation and insulin resistance in obese individuals.","PeriodicalId":72908,"journal":{"name":"Endocrines","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48730362","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}
