This study investigated the impact of intensive endurance exercise on circulating androgenic steroid hormones in women. Fifteen normally menstruating athletic women participated. They completed intensive endurance exercise (treadmill running) until volitional fatigue in their follicular phase, with blood samples collected at pre-exercise, volitional fatigue, 90 min and 24 h into recovery. The steroid hormones (total, free testosterone, dehydroepiandrosterone [DHEA], and DHEA-sulfate [DHEA-S], cortisol) were analyzed in blood sera. Non-parametric statistics were used to assess changes across exercise and recovery. At volitional fatigue, all hormones, except free testosterone, were significantly (p < 0.05) increased compared to pre-exercise levels. Most hormones remained elevated through 90 min of recovery, with DHEA, DHEA-S, and total testosterone changes being significant (p < 0.05). At 24 h of recovery, hormonal levels were reduced; specifically, DHEA, DHEA-S, and total testosterone compared to baseline (p < 0.01 to 0.06). Increases in cortisol levels at volitional fatigue and 90 min of recovery were correlated with reductions in total testosterone, DHEA, and DHEA-S observed at 24 h of recovery (rho > -0.62, p < 0.05). In conclusion, in menstruating women performing intensive endurance exercise during their follicular phase, their androgenic steroid hormones remain elevated during early recovery but are suppressed at 24 h of recovery. The latter finding indicates that establishing a resting endocrine equilibrium requires a longer recovery period than 24 h.

Growth hormone deficiency (GHD) is the most frequent pituitary hormone deficiency in childhood, with an incidence of 1 in 4000–10,000 live births. GHD can be congenital (genetic or due to hypothalamic/pituitary abnormalities) or acquired and can be isolated (IGHD) or associated with other pituitary hormone deficiencies, but most cases are idiopathic. GH stimulation testing is commonly used in the diagnostic workup of GHD, except for some clinical conditions that do not require GH stimulation tests for the diagnosis. Children with GHD receive replacement therapy with daily injections of recombinant human GH (rhGH). RhGH therapy is effective in increasing short-term height gain and adult height in patients with GHD. The safety of long term GH therapy has been confirmed in many large international studies. Recently, long-acting weekly GH formulations have been introduced, showing good efficacy and safety profiles.

For early hominids, frequent encounters with plant foods necessitated the ability to discern bitter poisons and adjust the activity of the gastrointestinal system in anticipation of carbohydrate-rich meals. Plants bitters were also used historically to manage a variety of metabolic and digestive disorders despite an immense structural diversity of bitter phytochemicals without a common molecular target. Our study confirms these observations in a standardized C57BL/6J prediabetic mouse model using 24 model compounds by demonstrating acute lower peak blood glucose values and improved glucose tolerance following intragastric, but not intraperitoneal, treatment. The administration of the synthetic bitter compound denatonium benzoate yielded similar results that were attenuated by co-application of the allosteric inhibitor of the bitter TAS2R receptors. We also show that these effects occur dose-dependently; associate with reduced glucose uptake, increased intracellular [Ca2+] fluxes, and enhanced GLP-1 expression; and are attenuated by the TAS2R inhibitor in the neuroendocrine STC-1 intestinal cells. These findings support the view that inhibition of glucose transport from the intestinal lumen to the blood by TAS2R bitter receptor signaling in the gut may represent a common mechanism in the acute response to oral ingestion of bitter phytochemicals.

While the exercise-induced responses of circulated biomarkers related to inflammation and brain health are well documented in humans, little is known about the effect of menopausal status on these responses. This study compared the responses of inflammatory cytokines and brain-derived neurotrophic factor (BDNF) to high-intensity exercise between pre- and postmenopausal middle-aged females. Eight premenopausal (44 ± 3 years) and seven postmenopausal (57 ± 2 years) females performed a high-intensity interval training (HIIT) session consisting of 10 × 1 min running intervals (90% maximum heart rate) separated by 1 min passive recovery intervals. Blood samples were collected at baseline (fasted), pre-exercise (postprandial), and at 0, 30, and 90 min post-HIIT and analyzed for interleukin (IL-6) and 10 (IL-10), tumour necrosis factor-alpha (TNF-α), and BDNF. IL-6 significantly increased from pre-exercise to 0 min post-HIIT in postmenopausal (+40%, p = 0.01) and to 30 min post-HIIT in premenopausal females (+60%, p = 0.02). IL-6 remained elevated at 90 min post-HIIT in premenopausal (+104%, p = 0.05) and to a higher degree in postmenopausal females (+385%, p < 0.001). IL-10 showed no response. TNF-α increased from pre- to 0 min post-HIIT (+10%, p = 0.05), then decreased to below pre-exercise at 30 min (−10%, p = 0.02) and 90 min (−5%, p = 0.04) in both groups. BDNF increased immediately post-HIIT in premenopausal (+60%, p < 0.001) but not postmenopausal females. The differences in IL-6 and BDNF responses to HIIT between pre- and postmenopausal females provide evidence of the role of female reproductive hormones in the regulation of these exercise-induced responses.

In total, 3274 adults (65.2% females) from six European countries were included in this cross-sectional analysis using data from the baseline assessment of the Feel4Diabetes study. Anthropometric, sociodemographic, dietary and behavioral data were assessed, and the existence of metabolic syndrome (MetS) was recorded. Beverage consumption patterns (BCPs) were derived via principal component analysis. Three BCPs were derived explaining 39.5% of the total variation. BCP1 was labeled as “Alcoholic beverage pattern”, which loaded heavily on high consumption of beer/cider, wine and other spirits; BCP2 was labeled as “High in sugars beverage pattern” that was mainly characterized by high consumption of soft drinks with sugar, juice containing sugar and low consumption of water; and BCP3 was labeled as “Healthy beverage pattern” that was mainly characterized by high consumption of water, tea, fruit juice freshly squeezed or prepacked without sugar and low consumption of soft drinks without sugar. After adjusting for various confounders, BCP2 was positively associated with elevated triglycerides (p = 0.001), elevated blood pressure (p = 0.001) elevated fasting glucose (p = 0.008) and the existence of MetS (p = 0.006), while BCP1 was inversely associated with reduced HDL-C (p = 0.005) and BCP3 was inversely associated with elevated blood pressure (p = 0.047). The establishment of policy actions as well as public health nutritional education can contribute to the promotion of a healthy beverage consumption.

Adrenocortical carcinoma (ACC) and pheochromocytoma (PCC) are malignancies originating from distinct layers of the adrenal gland. ACCs arise from the adrenal cortex, are often detected at advanced stages and are associated with poor prognosis. PCCs are mostly benign, arise from the adrenal medulla and have a variable prognosis, with 10% of PCCs resulting in metastasis. Genetic background strongly influences metastasis of PCCs, and no reliable biomarkers that predict metastatic behavior exist to date. Current therapeutic strategies for both ACCs and PCCs are overall limited. Thus, novel preclinical models and drug screening approaches need to be established to aid in the identification of more promising drugs and treatment schemes. In this review, we summarize the currently available human and murine cell lines for both tumor entities.

Background: Pregestational diabetes mellitus, if not well controlled, determines maternal and fetal complications. According to the new diagnostic criteria for gestational diabetes, the diagnosis of diabetes mellitus can also occur in early pregnancy (overt diabetes). Aim: This study aims to determine pregnancy outcomes in women with overt diabetes compared to women with pre-existing type 2 diabetes. Methods: In this retrospective study, we selected women with pre-existing type 2 and overt diabetes who had at least one pregnancy in the 2010–2022 period at the Diabetic Care Unit of Padova. Results: We analyzed 83 pregnancies, and overt diabetes was diagnosed in 18 pregnancies. In total, 95.5% of patients with overt diabetes and 48% of T2DM patients were immigrants (p < 0.143). No patients with overt diabetes planned their pregnancy, while pregnancy was planned in 26.3% of patients with pre-exiting type 2 diabetes (p < 0.05). Periconception and first-trimester glycemic control were the worst in patients with overt diabetes (HbA1c 9.7 ± 3.1% vs. 7.3% ± 2.3%, p < 0.044, at first visit; 8.1 ± 1.9% and 7.0 ± 1.6%, p < 0.037 in the first trimester) with respect to patients with pre-existing type 2 diabetes. As for maternal outcomes, 16.6% of pregnancies ended in miscarriage, and 5.5% of women developed gestational hypertension; as for newborn outcomes, 16.6% of newborns were LGA, and 11.1% were affected by congenital anomalies without any significant difference with respect to women with pre-existing type 2 diabetes. The high rate of congenital malformations in pregnancies of women with overt diabetes is probably a result of the poor, metabolic control observed during the periconception period when the organogenesis of the fetus takes place. Conclusions: It is essential to utilize procedures for diabetes screening in women of childbearing age not only at the beginning of the pregnancy, but also during the preconception phase or the postmenarcheal period when strong risk factors for diabetes onset are present, such as a high BMI, glycemic disorders, and those who fall under high-risk ethnicity categories.

Resveratrol is a natural polyphenol with important anti-inflammatory and antioxidant properties for treating cardiometabolic disorders. Therefore, the present meta-analysis aimed to review and investigate the oral resveratrol supplementation effects on metabolic syndrome (MetS) components. The bibliographic search was carried out in 2023 in the following databases: PubMed, Web of Science, and Scopus. Studies that investigated the oral resveratrol effects on the MetS parameters were included. Statistical analyses were performed using RevMan Software V.5.3. The main findings showed that resveratrol significantly decreased systolic and diastolic blood pressure while having no significant effects on waist circumference and high-density lipoprotein levels. In addition, glucose level was significantly decreased in the subgroup of studies reporting change from baseline means, although the overall effect was not statistically significant (p = 0.81), while triglyceride levels were increased after the treatment period. In conclusion, the present meta-analysis evidenced the potential therapeutic effect of resveratrol on improving some MetS features, especially regarding systolic blood pressure, diastolic blood pressure, and glucose reduction; however, the results are still borderline and sometimes controversial, which might be justified by the methodological and statistical heterogeneity of the studies, with the latter varying from 17 to 57%.

In conclusion, the present meta-analysis evidenced the potential therapeutic effect of resveratrol on improving some MetS features, especially regarding systolic blood pressure, diastolic blood pressure, and glucose reduction; however, the results are still borderline and sometimes controversial, which might be justified by the methodological and statistical heterogeneity of the studies, with the latter varying from 17 to 57%.","PeriodicalId":72908,"journal":{"name":"Endocrines","volume":"68 52","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141110335","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}

Basal insulin analogs, typically administered once or twice daily, have been one of the two pillars of the multiple daily injection (MDI) insulin therapy of patients with type 1 diabetes (T1D) for the last twenty years. Recently, once-weekly basal insulin analogs have been developed and are in late-phase clinical trials. One of these analogs is insulin icodec (icodec), appropriately developed to bind reversibly to albumin and to be gradually released into the patient’s circulation. Icodec has been tried mostly in clinical trials of adult patients with type 2 diabetes. A recent phase 3a clinical trial comprising adult patients with T1D was designed to evaluate icodec’s efficacy and safety compared with a daily basal insulin analog (degludec) after a 26-week main phase plus a safety extension of another 26 weeks. Icodec showed non-inferiority to once-daily degludec in glycated hemoglobin (HbA1c) reduction at week 26, and no significant differences in time in range (TIR) (70–180 mg/dL) and in time above range (TAR) (>180 mg/dL). On the other hand, it was associated with increased rates of clinically significant hypoglycemia (blood glucose < 54 mg/dL) and severe hypoglycemia (external assistance need for recovery), remaining either below or close to the internationally recommended targets for hypoglycemia. Another once-weekly insulin analog, basal insulin Fc (BIF), has been investigated in a phase 2 clinical trial comprising adult patients with T1D, with equally promising results. These preliminary data suggest that once-weekly insulin analogs could be of use for some patients with T1D, for example, patients not taking insulin regularly or those who are on MDI and wish for fewer injections. In addition, due to its prolonged mode of action, it could decrease the risk of diabetic ketoacidosis and the need for hospitalization. Additionally, patients with T1D that struggle with wearing diabetes mellitus devices/closed-loop insulin pumps either due to the cost or due to skin issues may also benefit from long-acting insulin. There is increasing evidence of the benefits of adjunctive therapies to insulin in T1D patients, but these therapies are not FDA-approved due to a possible higher risk of diabetic ketoacidosis. These long-acting insulin analogues could be used with adjunctive therapies in selected patients. This review aims to present available data on the mode of action, clinical trial results, and possible benefits of once-weekly insulin analogs for patients with T1D. In addition, it intends to suggest a future research framework for important clinical questions, such as once-weekly insulin analog use and exercise, sick days, or surgery, that will enhance our knowledge regarding this indisputable innovation in insulin management.

Adult-onset diabetes increases one’s risk of neurodegenerative disease including Alzheimer’s disease (AD); however, the risk associated with youth-onset diabetes (Y-DM) remains underexplored. We quantified plasma biomarkers of neurodegeneration and AD in participants with Y-DM from the SEARCH cohort at adolescence and young adulthood (Type 1, n = 25; Type 2, n = 25; 59% female; adolescence, age = 15 y/o [2.6]; adulthood, age = 27.4 y/o [2.2]), comparing them with controls (adolescence, n = 25, age = 14.8 y/o [2.7]; adulthood, n = 21, age = 24.9 y/o [2.8]). Plasma biomarkers, including glial fibrillary acidic protein (GFAP), neurofilament light chain protein (NfL), phosphorylated tau-181 (pTau181), and amyloid beta (Aβ40, Aβ42), were measured via Simoa. A subset of participants (n = 7; age = 27.5 y/o [5.7]) and six controls (age = 25.1 y/o [4.5]) underwent PET scans to quantify brain amyloid and tau densities in AD sensitive brain regions. Y-DM adolescents exhibited lower plasma levels of Aβ40, Aβ42, and GFAP, and higher pTau181 compared to controls (p < 0.05), a pattern persisting into adulthood (p < 0.001). All biomarkers showed significant increases from adolescence to adulthood in Y-DM (p < 0.01), though no significant differences in brain amyloid or tau were noted between Y-DM and controls in adulthood. Preliminary evidence suggests that preclinical AD neuropathology is present in young people with Y-DM, indicating a potential increased risk of neurodegenerative diseases.
