Abstract
Sleep deprivation has become increasingly prevalent in contemporary society, and the consequences of this reality such as cognitive impairment and metabolic disorders, are widely investigated in the scientific scenario. However, the impact of sleep deprivation on the health of future generations is a challenge, and researchers are focusing their attention on this issue. Thus, this review aims to describe the impact of sleep deprivation in early life in animal models, particularly rodents, discussing the molecular physiology impacted by prolonged wakefulness in early life, as well as the changes that interfere with neurodevelopmental processes. Additionally, it explores the changes impacting metabolic mechanisms and discusses both the short- and long-term consequences of these processes on endocrine, behavioral, and cognitive functions. Finally, we briefly address some strategies to mitigate the adverse effects of sleep deprivation.

Abstract
Bisphenols (BPs) have become a chemical group of special interest due to their ability to interfere with the endocrine system and their ubiquitous presence in the environment. As some of them possess mild estrogenic and anti-androgenic effects, they might be associated with the diagnosis of polycystic ovary syndrome (PCOS). Acting on multiple tissues, BPs exposure may lead to metabolic derangements characteristic for metabolic syndrome (MetS). Therefore, the aim of this study was to determine the potential relationship between exposure to some BPA analogues and features of the MetS in women with PCOS. Serum BPE, BPC, BPG, BPM, BPP, BPZ, BPFL, and BPBP concentrations did not differ significantly between the PCOS (n = 135) and the control subjects (n = 104). However, women whose serum BPM and BPP concentrations were in the highest tertile were more likely to be diagnosed with PCOS (adjusted OR; [95%CI] 0.43; [0.20; 0.89], P < 0.001 and 0.56; [0.27; 0.96], P = 0.049, consequently). Serum concentrations of BPs were not associated with the MetS diagnosis in the PCOS group. There was a negative correlation between the concentrations of serum BPBP and total serum cholesterol (r = - 0.153; P = 0.019), BPE and serum testosterone (r = - 0.160; P = 0.014) as well as BPC and HDL-cholesterol (r = - 0.138; P = 0.036). There was a positive correlation between the concentrations of BPP and serum triglycerides (r = 0.138; P = 0.036). Our results point to the potential association between exposure to BPM, BPP, and the diagnosis of PCOS, along with the impact of BPBP, BPE, BPC, and BPP on the metabolic features of the MetS.

Abstract
Objective To explore the comparative effectiveness of nutritional supplements in improving glycolipid metabolism and endocrine function in patients with polycystic ovary syndrome (PCOS). Method Randomized controlled clinical trials on the effects of nutritional supplements in PCOS patients were searched in PubMed, Embase, Cochrane Library, and Web of Science from their establishments to March 15, 2023. Then, literature screening, data extraction, and network meta-analysis were performed. This study was registered at PROSPERO (registration number CRD 42023441257). Result Forty-one articles involving 2,362 patients were included in this study. The network meta-analysis showed that carnitine, inositol, and probiotics reduced body weight and body mass index (BMI) compared to placebo, and carnitine outperformed the other supplements (SUCRAs: 96.04%, 97.73%, respectively). Omega-3 lowered fasting blood glucose (FBG) (SUCRAs: 93.53%), and chromium reduced fasting insulin (FINS) (SUCRAs: 72.90%); both were superior to placebo in improving insulin resistance index (HOMA-IR), and chromium was more effective than Omega-3 (SUCRAs: 79.99%). Selenium was potent in raising the quantitative insulin sensitivity index (QUICKI) (SUCRAs: 87.92%). Coenzyme Q10 was the most effective in reducing triglycerides (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) levels (SUCRAs: 87.71%, 98.78%, and 98.70%, respectively). Chromium and probiotics decreased TG levels, while chromium and vitamin D decreased TC levels. No significant differences were observed in high-density lipoprotein cholesterol (HDL-C), total testosterone (TT), sex-hormone binding globulin (SHBG), and C-reactive protein (CRP) between nutritional supplements and placebo. Conclusion Carnitine was relatively effective in reducing body mass, while chromium, Omega-3, and selenium were beneficial for improving glucose metabolism. Meanwhile, coenzyme Q10 was more efficacious for improving lipid metabolism. However, publication bias may exist, and more high-quality clinical randomized controlled trials are needed.

Abstract
BACKGROUND Ovarian insufficiency frequently renders postmenopausal women susceptible to osteoporosis and dyslipidaemia. Postmenopausal transplant women are at a higher risk developing osteoporosis and dyslipidaemia due to the concomitant application of glucocorticoids and immunosuppressants after solid organ transplantation. Thus, this study aimed to explore the feasibility of ovarian tissue transplantation (OTT) as an alternative to Hormone replacement therapy (HRT) for postmenopausal women with solid organ transplant needs. RESULTS Sixty mice were randomly divided into four groups: sham operation, ovariectomised (OVX group), ovariectomy plus oestrogen (E2 group), and ovariectomy plus OTT (OTT group). The inhibin levels in the OTT group were increased and the follicle stimulating hormone and luteinizing hormone were suppressed to normal levels, which could not be achieved in the E2 group. The femoral bone mineral density in the OTT group was significantly increased than the E2 group (P < 0.05), and the probability of fracture was reduced by 1.4-2.6 times. Additionally, the high-density lipoprotein cholesterol levels were higher in the OTT group than in the E2 group and the triglyceride levels were lower in the OTT group than in the E2 group (P < 0.05). CONCLUSION OTT not only achieves certain endocrine effects by participating in the regulation of the hypothalamic-pituitary-ovarian feedback control loop, but also ameliorates osteoporosis and dyslipidaemia, which may be an alternative to traditional HRT for postmenopausal women with solid organ transplant needs.

Abstract
BACKGROUND For tumors in the neck and body of the pancreas, distal pancreatectomy (DP) has been the standard surgical procedure for the last few decades and central pancreatectomy (CP) is an alternative surgical option. Whether CP better preserves remnant pancreatic endocrine and exocrine functions after surgery remains a subject of debate.
AIM To evaluate the safety and efficacy of CP compared with DP for benign or low-grade malignant pancreatic tumors in the neck and body of the pancreas.
METHODS This retrospective study enrolled 296 patients who underwent CP or DP for benign and low-malignant neoplasms at the same hospital between January 2016 and March 2020. Perioperative outcomes and long-term morbidity of endocrine/exocrine function were prospectively evaluated.
RESULTS No significant difference was observed in overall morbidity or clinically relevant postoperative pancreatic fistula between the two groups (P = 0.055). Delayed gastric emptying occurred more frequently in the CP group than in the DP group (29.4% vs 15.3%; P < 0.005). None of the patients in the CP group had new-onset or aggravated distal metastasis, whereas 40 patients in the DP group had endocrine function deficiency after surgery (P < 0.05). There was no significant difference in the incidence of diarrhea immediately after surgery, but at postoperative 12 mo, a significantly higher number of patients had diarrhea in the DP group than in the CP group (0% vs 9.5%; P < 0.05).
CONCLUSION CP is a generally safe procedure and is better than DP in preserving long-term pancreatic endocrine and exocrine functions. Therefore, CP might be a better option for treating benign or low-grade malignant neoplasms in suitable patients.

Abstract
INTRODUCTION Children with craniopharyngiomas (CP) can experience significant morbidities caused by extensive surgery and/or radiation. Ommaya reservoir insertion (ORI) into cystic CP represents a minimally invasive approach allowing immediate decompression and aims to avoid additional injuries. The purpose of this study was to determine the surgical outcome and relevance of upfront ORI (± intracystic treatment) for preservation of endocrine function. METHODS We performed a retrospective chart review of children with CP treated at the Hospital for Sick Children between 01/01/2000 and 15/01/2020. Endocrine function was reviewed at the time of initial surgery and throughout follow-up. New endocrinological deficits related to the index procedure were defined as immediate failure (IF), whereas postoperative duration of endocrinological stability (ES) was analyzed using the Kaplan-Meier method. The rate of IF and ES was compared between the treatment groups. RESULTS Seventy-nine patients were included and had a median age of 8.3 years (range 2.1-18.0 years); 31 were males. Fifty-three patients with upfront surgical treatment, including 29 ORI and 24 gross total or partial resections had sufficient endocrinological follow-up data. Endocrine dysfunction occurring immediately after the index procedure (IF) was observed in 15 patients (62.5%) in the resection group compared to two patients (6.8%) in the ORI group, odds ratio: 0.05 (CI: 0.01-0.26, p < 0.0001). Excluding those with immediate endocrinological deficits, mean ES after ORI was 19.4 months (CI: 11.6-34.2), compared to 13.4 months (CI:10.6-NA) after surgical resection. CONCLUSIONS Endocrine function was preserved in patients with upfront ORI (± intracystic treatment), which was confirmed as a minimally invasive procedure with an overall low morbidity profile.

Abstract
INTRODUCTION Transsphenoidal surgery is the current treatment for mass reduction in patients with non-functional pituitary adenomas (NFPAs). The surgical procedure may deteriorate or recover pituitary endocrine function. The aim of this study was to systematically assess the benefits and harms of transsphenoidal surgery on pituitary endocrine function in patients with NFPAs. METHODS This systematic review and meta-analysis was registered with PROSPERO (registration No. CRD42020210853). We searched Pubmed and EMBASE for studies reporting on pituitary function before and after transsphenoidal surgery in patients with NFPAs having a minimum follow-up of 1 month. The prespecified primary outcomes were the proportions of patients with improved or deteriorated pituitary function after surgery reported as weighted mean using random effects meta-analysis or in case of considerable heterogeneity, i.e., I2 ≥ 75%, as a range of reported proportions. Subgroup analyses were planned for the primary outcomes on study level. RESULTS Of the 6,597 identified records, 24 studies enrolling 3,816 participants were eligible for assessment. Twenty-three studies were judged to have serious or critical risk of bias. The range of proportions of patients with recovery of at least one pituitary axis was between 10.2% and 97.7% (I2 = 93%), while the range of proportions of patients experiencing loss of at least one axis after pituitary surgery was between 0.0% and 36.6% (I2 = 91%). None of the a priori planned subgroup analyses explained the observed heterogeneity associated with deterioration of pituitary function after surgery, and the proportion of patients may be underestimated due to publication bias. CONCLUSIONS The current systematic review finds that the endocrine effect of pituitary surgery is unclear both in terms of the chance of recovery and in terms of the risk of pituitary failure and hypopituitarism should be considered only a relative indication for surgery. However, the range of effects does include potentially clinically relevant rates of pituitary recovery calling for more systematic collection of data in future studies.

Abstract
The liver, the largest solid visceral organ of the body, has numerous endocrine functions, such as direct hormone and hepatokine production, hormone metabolism, synthesis of binding proteins, and processing and redistribution of metabolic fuels. In the last 10 years, many new endocrine functions of the liver have been discovered. Advances in the classical endocrine functions include delineation of mechanisms of liver production of endocrine hormones [including 25-hydroxyvitamin D, insulin-like growth factor 1 (IGF-1), and angiotensinogen], hepatic metabolism of hormones (including thyroid hormones, glucagon-like peptide-1, and steroid hormones), and actions of specific binding proteins to glucocorticoids, sex steroids, and thyroid hormones. These studies have furthered insight into cirrhosis-associated endocrinopathies, such as hypogonadism, osteoporosis, IGF-1 deficiency, vitamin D deficiency, alterations in glucose and lipid homeostasis, and controversially relative adrenal insufficiency. Several novel endocrine functions of the liver have also been unraveled, elucidating the liver’s key negative feedback regulatory role in the pancreatic α cell-liver axis, which regulates pancreatic α cell mass, glucagon secretion, and circulating amino acid levels. Betatrophin and other hepatokines, such as fetuin-A and fibroblast growth factor 21, have also been discovered to play important endocrine roles in modulating insulin sensitivity, lipid metabolism, and body weight. It is expected that more endocrine functions of the liver will be revealed in the near future.

Abstract
BACKGROUND Transsphenoidal surgery (TSS) remains the treatment of choice for non-functioning pituitary macroadenomas (NFPMA). The value of measuring tumour volumes before and after surgery, and its influence on endocrine outcomes and further treatment of the residual or recurrent tumour are unknown. METHODS Data from patients who underwent endoscopic TSS for a NFPMA (2009-2018) in a UK tertiary centre were analysed for pre- and post-operative endocrine and surgical outcomes. RESULTS Of 173 patients with NFPMA, 159 (61% male) were treatment naïve. At presentation, 76.2% (77/101) had ≥1 pituitary axis deficit. Older age (p = 0.002) was an independent predictor for multiple hormonal deficiencies. Preoperative tumour volume did not correlate with degree of hypopituitarism. Postoperative tumour volume and extent of tumour resection were not predictive of new onset hypopituitarism. Hormonal recovery was observed in 16 patients (20.8%) with impaired pituitary function, with the greatest recovery in the hypothalamic-pituitary-adrenal axis (21.2%, 7/33). A larger residual tumour volume was predictive of adjuvant radiotherapy (3.40 vs. 1.24 cm3, p = 0.005) and likelihood for repeat surgery (5.40 vs. 1.67cm3, p = 0.004). CONCLUSION Pre- and post-operative NFPMA volumes fail to predict the number of pituitary hormone deficits, however, greater post-operative residual volumes increase the likelihood of further intervention to control tumour growth.

Abstract
Bone-derived cytokines refer to various proteins and peptides that are released from the skeleton and can distribute in organisms to regulate homeostasis by targeting many organs, such as the pancreas, brain, testicles, and kidneys. In addition to providing support and movement, many studies have disclosed the novel endocrine function of bone, and bone can modulate glucose and energy metabolism as well as phosphate metabolism by versatile bone-derived cytokines. However, this specific exoskeletonfunction of bone-derived cytokines in the regulation of homeostasis and the pathological response caused by skeletal dysfunction are still not very clear, and elucidation of the above mechanisms is of great significance for understanding the pathological processes of metabolic disorders and in the search for novel therapeutic measures for maintaining organ stability and physical fitness.

Abstract
BACKGROUND Pancreatic endocrine insufficiency after acute pancreatitis (AP) has drawn increasing attention in recent years.
AIM To assess the impact of risk factors on the development of pancreatic endocrine insufficiency after AP.
METHODS This retrospective observational long-term follow-up study was conducted in a tertiary hospital. Endocrine function was evaluated by the oral glucose tolerance test. The data, including age, sex, body mass index, APACHE II score, history of smoking and drinking, organ failure, pancreatic necrosis, debridement of necrosis (minimally invasive and/or open surgery), and time interval, were collected from the record database.
RESULTS A total of 361 patients were included in the study from January 1, 2012 to December 30, 2018. A total of 150 (41.6%) patients were diagnosed with dysglycemia (including diabetes mellitus and impaired glucose tolerance), while 211 (58.4%) patients had normal endocrine function. The time intervals (mo) of the above two groups were 18.73 ± 19.10 mo and 31.53 ± 27.27 mo, respectively (P = 0.001). The morbidity rates of pancreatic endocrine insufficiency were 46.7%, 28.0%, and 25.3%, respectively, in the groups with different follow-up times. The risk factors for pancreatic endocrine insufficiency after AP were severity (odds ratio [OR] = 3.489; 95% confidence interval [CI]: 1.501-8.111; P = 0.004) and pancreatic necrosis (OR = 4.152; 95%CI: 2.580-6.684; P = 0.001).
CONCLUSION Pancreatic necrosis and severity are independent risk factors for pancreatic endocrine insufficiency after AP. The area of pancreatic necrosis can affect pancreatic endocrine function.

Abstract
Backgrounds/Aims This study was done with the aim of assessing impact of surgery for chronic pancreatitis on exocrine and endocrine functions, quality of life and pain relief of patients. Methods 35 patients of chronic pancreatitis who underwent surgery were included. Exocrine function assessed with fecal fat globule estimation and endocrine function assessed with glycated haemoglobin (HbA1C), fasting plasma glucose (FPG), Insulin and C-peptide levels. Percentage (%) beta cell function by homeostatic model assessment (HOMA) was determined using web-based calculator. Quality of life (QOL) and pain assessment was done using Short form survey (SF-36) questionnaire and Izbicki scores respectively. Follow up done till 3 months following surgery. Results Endocrine insufficiency was noted in 13 (37%) patients in the postoperative period compared to 17 (49%) patients preoperatively (p=0.74). Exocrine insufficiency was detected in 11 (32%) patients postoperatively compared to 8 (23%) patients preoperatively, with denovo insufficiency noted in 3 (8%) patients (p<0.05). The mean Izbicki score at 3 months postoperatively was remarkably lower compared to preoperative score (29.3±14.3 vs. 60.6±12.06; p<0.05). QOL at 3 months following surgery for chronic pancreatitis was significantly better than preoperative QOL (50.24±22.16 vs. 69.48±20.81; p<0.05). Conclusions Significant pain relief and improvement in quality of life among patients of chronic pancreatitis following surgery. However, worsening of exocrine function with only clinical improvement of endocrine function was also noted.

Abstract
The present study aimed to evaluate the structure, survival and development of isolated caprine (secondary-SEC and early antral-EANT) follicles, after vitrification in the presence of synthetic polymers and in vitro culture. Additionally, transzonal projections (TZPs) and p450 aromatase enzyme were evaluated. After isolation, SEC and EANT follicles were in vitro cultured for six days or vitrified. After one week, SEC and EANT follicles were warmed and also in vitro cultured for six days. Data revealed that the percentage of morphologically normal follicles was similar between fresh and vitrified follicles in both follicular categories and antrum formation rate was similar between fresh and vitrified SEC follicles. Fluorescence by calcein-AM did not show difference between fresh and vitrified (SEC and EANT) follicles, however, the trypan blue test showed low viability for vitrified follicles. The integrity of TZPs was not affected between fresh and vitrified SEC follicles, however, in vitrified EANT follicles, there were signs of TZPs loss. Regarding steroidogenic function, it was observed a positive staining for p450 aromatase enzyme in fresh and vitrified SEC and EANT follicles. It was concluded that SEC follicles seem to be more resistant to vitrification than EANT follicles, as shown by the trypan blue test and TZPs assay. Future studies may confirm this hypothesis, in order to consolidate the use of SEC and EANT follicles as an alternative to ovary cryopreservation.

Abstract
PURPOSE Myotonic dystrophy type 1 (DM1) is a genetic disorder caused by CTG expansion in the DMPK gene. The aim was to investigate the endocrine and metabolic aspects of DM1. PATIENTS AND METHODS Retrospective, case-control study. We compared pituitary, thyroid, adrenal, gonadal and liver function and glycolipid metabolism of 63 DM1 patients against 100 control subjects. Given age-related differences, 2 further subgroups were created to investigate the pituitary-gonadal axis: < 41 (1a) and ≥ 41 (1b) years old for male subjects and < 46 (2a) and ≥ 46 (2b) years old for female subjects. Testicular and thyroid ultrasounds were also performed in the DM1 group. RESULTS FT3 and FT4 were significantly lower in DM1 men than controls, while for both males and females, thyroglobulin, ACTH and cortisol were significantly higher in the DM1 group. Gonadotropin levels were significantly higher and inhibin B and DHEA-S levels significantly lower in DM1 patients than controls for both male subgroups. Testosterone and SHBG were significantly higher in controls than in patients for subgroup 1a. Prolactin was significantly higher in patients in subgroups 1b, while testosterone was lower in subgroup 2a than in age-matched female controls. A correlation between the number of CTG repeats and the percentage of male hypogonadal subjects was found. Finally, there was a worse glucose and lipid pattern and significantly higher transaminase and gamma-GT levels in both male and female patients. CONCLUSIONS The high frequency of endocrine and metabolic abnormalities in DM1 highlights the importance of endocrine monitoring to enable the prompt initiation of a suitable therapy.

Abstract
BACKGROUND Premature ovarian insufficiency (POI) and premature ovarian failure (POF) have become one of the major problems threatening women of childbearing age. Studies have shown that stem cells transplanted from bone marrow, umbilical cord, peripheral blood and amniotic fluid can migrate and proliferate to the ovary, promote ovarian function repair, increase the number of follicles and granulosa cells at all levels of ovary, improve endocrine function, and can differentiate into oocytes in specific ovarian environment to restore fertility to some extent.
AIM To study the ability of human umbilical cord mesenchymal stem cells (hUCMSCs) to repair ovarian injury after chemotherapy.
METHODS A total of 110 female BALB/c mice (aged 7-8 wk old) with body masses of 16.0-20.0 g were selected. The mice were fed until 12 wk of age, and cyclophosphamide was administered by intraperitoneal injection for 14 consecutive days to induce premature ovarian failure in mice. Seventy-five mice with estrous cycle disorder were screened and randomly divided into 3 groups according to their body weight: model group, positive control group and hUCMSC group, and each group had 25 mice. Another 25 mice were used as negative controls. The mice in the hUCMSC group were injected with hUCMSCs in the tail vein, and the mice in the positive control group were given an oestradiol valerate solution and a medroxyprogesterone acetate solution in the tail vein. On the 1st, 15th, 30th, 45th, and 60th days after intravenous administration, vaginal smears were made to monitor the estrous cycles of the mice. The ovaries were weighed, and pathological sections were made to observe the morphology of the follicles; blood samples were collected to monitor the concentration of sex hormones (oestradiol and follicle-stimulating hormone).
RESULTS The estrous cycles of the model group mice were disrupted throughout the experiment. Mice in the hUCMSC group and the positive control group resumed normal estrous cycles. The ovarian weight of the model group mice continued to decline. The ovarian weight of the hUCMSC group mice and the positive control group mice decreased first and then gradually increased, and the ovarian weight of the hUCMSC group mice was heavier than that of the positive control group mice. The difference was statistically significant (P < 0.05). Compared with the negative control group, the model group experienced a decrease in oestradiol and an increase in follicle-stimulating hormone, and the difference was statistically significant (P < 0.05). Compared with the model group, the hUCMSC and positive control groups experienced a slight increase in oestradiol and a decrease in follicle-stimulating hormone; the difference was statistically significant (P < 0.05). The pathological examination revealed that the mouse ovaries from the model group were atrophied, the volume was reduced, the cortical and medullary structures were disordered, the number of follicles at all stages was significantly reduced, the number of atretic follicles increased, the number of primordial follicles and corpus luteum significantly decreased, and the corpus luteum had an irregular shape. Compared with those of the model group, the lesions of the hUCMSC and positive control groups significantly improved.
CONCLUSION hUCMSCs can repair ovarian tissue damaged by chemotherapy to a certain extent, can improve the degree of apoptosis in ovarian tissue, and can improve the endocrine function of mouse ovaries.

Abstract
OBJECTIVE The objective was to find the role of long-non-coding RNA zinc finger antisense 1 (lncRNA ZFAS1)/microRNA (miR)-129/high-mobility group box protein 1 (HMGB1) axis in polycystic ovary syndrome (PCOS). METHODS Ovarian granulosa cells from non-PCOS patients and PCOS patients were collected, and HMGB1, miR-129 and lncRNA ZFAS1 expression were detected. Ovarian granulosa cells were transfected with si-ZFAS1 or miR-129 mimics to verify their roles in P4 and E2 secretion, and the biological functions of ovarian granulosa cells. RESULTS LncRNA ZFAS1 and HMGB1 were elevated, while miR-129 was down-regulated in ovarian granulosa cells of PCOS patients. Down-regulated lncRNA ZFAS1 or overexpressed miR-129 could decrease HMGB1 expression, increase P4 and E2 secretion, promote proliferation activity while inhibit apoptosis of ovarian granulosa cells in PCOS. CONCLUSION LncRNA ZFAS1 could bind to miR-129 to promote HMGB1 expression, thereby affecting the endocrine disturbance, proliferation and apoptosis of ovarian granulosa cells in PCOS.

Abstract
BACKGROUND Pancreaticogastrostomy (PG) has been widely used as an alternative to pancreatojejunostomy (PJ) in patients undergoing pancreaticoduodenectomy (PD), but its long-term exocrine function remains unclear. The present study aimed to measure the secretion of pancreatic α-amylase (p-AMY) into the gastric cavity in patients who underwent PG reconstruction after PD over 1 year after surgery and to evaluate the relationship between gastric p-AMY level and clinically available indirect tests. METHODS Clinical records of 39 patients who underwent PG reconstruction after PD were reviewed. Pancreatic exocrine function was evaluated over 1 year after surgery using the following methods: 1) Measurement of p-AMY level in gastric fluids (gastric p-AMY level) during routine gastrointestinal endoscopy, 2) Qualitative faecal fat determination by Sudan III staining on faeces and 3) Pancreatic function diagnostic (PFD) test using oral administration of N-benzoyl-l-tyrosyl-p-aminobenzoic acid. RESULTS Gastric p-AMY level was detectable in 31 of 39 patients (79%), and 12 patients (30.8%) had steatorrhea over a year after surgery. Patients with steatorrhea had significantly lower gastric p-AMY level, larger diameter of remnant main pancreatic duct (MPD) and larger pancreatic duct to parenchymal thickness ratio than those without steatorrhea (84 IU/L vs 7979 IU/L, respectively; P < 0.001, 5.3 mm vs 3.2 mm, respectively; P = 0.001, and 0.38 vs 0.23, respectively; P = 0.007). Receiver operating characteristic analysis showed that the cut-off value of the diameter of the remnant MPD to predict steatorrhea was 3.5 mm (sensitivity, 92.3%; specificity, 70.4%). PFD test was not associated with any clinical data. CONCLUSIONS Pancreatic enzyme was detected in 79% of patients having PG reconstruction. Diameter of remnant MPD >3.5 mm and pancreatic parenchymal atrophy may be surrogate markers of postoperative exocrine insufficiency following PD.

Abstract
TBP is a natural product from Tamarindus indica L. seeds used as a natural remedy in India. This product is an antioxidant and may have beneficial effects on endocrine and metabolic functions. However, the regulatory mechanisms involved remain to be elucidated. In males, testosterone is synthesized by Leydig cells from the testis. With aging and obesity, testis function declines, leading to decreased testosterone synthesis. The aim of the current research is to determine how TBP improves testosterone production in male mice under a high fat diet leading to hypoandrogenic condition. Using C2C12 myoblast cells, we have found that TBP increased mitochondrial mass and oxygen respiration, as well as the production of the IGF-1 hormone. In addition, treatment of TM3 Leydig cells with TBP resulted in increased testosterone production. In mice under a high fat diet, TBP lowered blood glucose level and corticosterone production and improved total testosterone production after five weeks of treatment. In addition, testicular expressions of genes encoding the mitochondrial transporter of cholesterol (Star) and steroidogenic enzymes (Cyp11a1, Hsd3b1, Cyp17a1 and Hsd17b3) were increased by TBP. Hence, TBP may prevent the detrimental effects of long-term consumption of a high fat diet and may have health benefits on the endocrine function.

Abstract
PURPOSE OF REVIEW An elevated level of pro-inflammatory cytokines in inflammatory conditions causes bone loss and disrupts vital organ function. Osteocytes comprise > 95% of the cellular component in bone tissue, produce a range of cytokines and signaling molecules, and influence bone and other organ function. In this review, we hypothesized that an elevated level of pro-inflammatory cytokines in inflammatory conditions affects osteocyte survival and function thereby possibly amplifying inflammation, and causing bone loss and non-bone clinical complications. RECENT FINDINGS Several studies have reported that the elevated level of pro-inflammatory cytokines in inflammatory conditions alters osteocyte mechanosensitivity, causes osteocyte apoptosis, and modulates osteocyte-derived production of various inflammatory cytokines and signaling molecules. Cytokines and signaling molecules released from osteocytes affect surrounding bone cells and distant organ function in a paracrine and endocrine fashion. Inflammatory diseases including diabetes, chronic kidney disease, rheumatoid arthritis, and periodontitis affect osteocyte survival and function, and upregulate osteocyte-derived expression of sclerostin, RANKL, TNFα, FGF23, DKK1, and other signaling molecules.

Abstract
Objective: To summarize the etiologies of bilateral adrenal lesions and the changes of the disease profile in hospitalized patients. Methods: Bilateral adrenal lesion screening was conducted in all patients admitted to Peking University Third Hospital from 1994 to 2017. The etiologies and disease profiles of bilateral adrenal lesions were retrospectively analyzed. Results: A total of 260 patients with bilateral adrenal lesions were included in the study. There were 146 males and 114 females with a mean age of (55.4±16.2) years. The most common adrenal lesion was bilateral adrenal hyperplasia (75 cases, 28.8%), followed by bilateral adrenal adenomas (71 cases, 27.3%), metastatic carcinoma (51 cases, 19.6%), discordant bilateral adrenal lesions (27 cases, 10.4%), bilateral pheochromocytomas (13 cases, 5.0%), and others. The clear data of endocrine function evaluation could be found in 184 patients. Among them, 111 cases (60.3%) were nonfunctioning lessions, 34 cases (18.5%) with primary aldosteronism, 15 cases (8.1%) with pheochromocytoma, 13 cases (7.1%) with congenital adrenal hyperplasia, 6 cases (3.3%) with primary hypoadrenocorticism, and 5 cases (2.7%) with Cushing syndrome. Using every 8 years as a period of time, the number of hospitalized patients with bilateral adrenal lesions increased with years in three periods (8, 41 and 211 cases, respectively). Conclusions: The most common cause of bilateral adrenal lesions is adrenal hyperplasia in the hospitalized patients. More than half of bilateral adrenal lesions are nonfunctioning. In functional bilateral lesions, primary aldosteronism and pheochromocytoma account for a large proportion.

Abstract
There is considerable physiological and clinical evidence of harm and increased risk of death associated with dysglycemia in critical care. However, glycemic control (GC) currently leads to increased hypoglycemia, independently associated with a greater risk of death. Indeed, recent evidence suggests GC is difficult to safely and effectively achieve for all patients. In this review, leading experts in the field discuss this evidence and relevant data in diabetology, including the artificial pancreas, and suggest how safe, effective GC can be achieved in critically ill patients in ways seeking to mimic normal islet cell function. The review is structured around the specific clinical hurdles of: understanding the patient’s metabolic state; designing GC to fit clinical practice, safety, efficacy, and workload; and the need for standardized metrics. These aspects are addressed by reviewing relevant recent advances in science and technology. Finally, we provide a set of concise recommendations to advance the safety, quality, consistency, and clinical uptake of GC in critical care. This review thus presents a roadmap toward better, more personalized metabolic care and improved patient outcomes.

Abstract
The genomics era has brought along the completed sequencing of a large number of bird genomes that cover a broad range of the avian phylogenetic tree (>30 orders), leading to major novel insights into avian biology and evolution. Among recent findings, the discovery that birds lack a large number of protein coding genes that are organized in highly conserved syntenic clusters in other vertebrates is very intriguing, given the physiological importance of many of these genes. A considerable number of them play prominent endocrine roles, suggesting that birds evolved compensatory genetic or physiological mechanisms that allowed them to survive and thrive in spite of these losses. While further studies are needed to establish the exact extent of avian gene losses, these findings point to birds as potentially highly relevant model organisms for exploring the genetic basis and possible therapeutic approaches for a wide range of endocrine functions and disorders.

Abstract
Mercury is a ubiquitous environmental contaminant known to accumulate in, and negatively affect, fish-eating and oceanic bird species, and recently demonstrated to impact some terrestrial songbirds to a comparable extent. It can bioaccumulate to concentrations of >1 μg/g in tissues of prey organisms such as fish and insects. At high enough concentrations, exposure to mercury is lethal to birds. However, environmental exposures are usually far below the lethal concentrations established by dosing studies.The objective of this review is to better understand the effects of sublethal exposure to mercury in birds. We restricted our survey of the literature to studies with at least some exposures >5 μg/g. The majority of sublethal effects were subtle and some studies of similar endpoints reached different conclusions. Strong support exists in the literature for the conclusion that mercury exposure reduces reproductive output, compromises immune function, and causes avoidance of high-energy behaviors. For some endpoints, notably certain measures of reproductive success, endocrine and neurological function, and body condition, there is weak or contradictory evidence of adverse effects and further study is required. There was no evidence that environmentally relevant mercury exposure affects longevity, but several of the sublethal effects identified likely do result in fitness reductions that could adversely impact populations. Overall, 72% of field studies and 91% of laboratory studies found evidence of deleterious effects of mercury on some endpoint, and thus we can conclude that mercury is harmful to birds, and the many effects on reproduction indicate that bird population declines may already be resulting from environmental mercury pollution.

Abstract
The concept of foetal programming (FP) originated from human epidemiological studies, where foetal life nutrition was linked to health and disease status later in life. Since the proposal of this phenomenon, it has been evaluated in various animal models to gain further insights into the mechanisms underlying the foetal origins of health and disease in humans. In FP research, the sheep has been quite extensively used as a model for humans. In this paper we will review findings mainly from our Copenhagen sheep model, on the implications of late gestation malnutrition for growth, development, and metabolic and endocrine functions later in life, and discuss how these implications may depend on the diet fed to the animal in early postnatal life. Our results have indicated that negative implications of foetal malnutrition, both as a result of overnutrition and, particularly, late gestation undernutrition, can impair a wide range of endocrine functions regulating growth and presumably also reproductive traits. These implications are not readily observable early in postnatal life, but are increasingly manifested as the animal approaches adulthood. No intervention or cure is known that can reverse this programming in postnatal life. Our findings suggest that close to normal growth and slaughter results can be obtained at least until puberty in animals which have undergone adverse programming in foetal life, but manifestation of programming effects becomes increasingly evident in adult animals. Due to the risk of transfer of the adverse programming effects to future generations, it is therefore recommended that animals that are suspected to have undergone adverse FP are not used for reproduction. Unfortunately, no reliable biomarkers have as yet been identified that allow accurate identification of adversely programmed offspring at birth, except for very low or high birth weights, and, in pigs, characteristic changes in head shape (dolphin head). Future efforts should be therefore dedicated to identify reliable biomarkers and evaluate their effectiveness for alleviation/reversal of the adverse programming in postnatal life. Our sheep studies have shown that the adverse impacts of an extreme, high-fat diet in early postnatal life, but not prenatal undernutrition, can be largely reversed by dietary correction later in life. Thus, birth (at term) appears to be a critical set point for permanent programming in animals born precocial, such as sheep. Appropriate attention to the nutrition of the late pregnant dam should therefore be a priority in animal production systems.

Abstract
Premature ovarian insufficiency (POI) is a major complication of cytotoxic treatments due to extreme ovarian sensitivity to chemotherapy and radiation. In pediatric cancer patients modern therapy has improved the long-term survival to over 80% in the United States. However, these cancer survivors face long-term health problems related to treatment toxicity. In female cancer survivors POI leads to sterility, along with the consequences of estrogen deficiency such as premature osteopenia, muscle wasting, accelerated cardiovascular diseases and a vast array of other health and developmental problems. These long-lasting effects are particularly significant for young girls reaching puberty. As such, restoring ovarian endocrine function is paramount in this population. In the present study, we evaluated the feasibility of restoring ovarian endocrine function in ovariectomized mice by transplanting syngeneic and allogeneic ovarian tissue encapsulated in alginate capsules or TheraCyte®. Histological analysis of the implants retrieved after 7 and 30 days' post implantation showed follicular development up to the secondary and antral stages in both syngeneic and allogeneic implants. Implantation of syngeneic and allogeneic ovarian grafts encapsulated in TheraCyte devices restored ovarian endocrine function, which was confirmed by decreased serum FSH levels from 60 to 70 ng/mL in ovariectomized mice to 30-40 ng/mL 30 days after implantation. Absence of allo-MHC-specific IgG and IgM antibodies in the sera of implanted mice with allogeneic ovarian tissue encapsulated in TheraCyte indicate that the implants did not evoke an allo-immune response, while the allogeneic controls were rejected 21 days after implantation. Our results show that TheraCyte effectively isolates the graft from immune recognition but also supports follicular growth.

Abstract
OBJECTIVE Previous reports on the prevalence of diabetes in pancreatic cancer and chronic pancreatitis patients are based on inconsistent and equivocal criteria. The objective of this study is to prospectively assess with conclusive methods the preoperative glycaemic status of patients undergoing pancreatic surgery. We hypothesise that most of those patients are unaware of these disturbances in glycaemic status and that the prevalence is underestimated. METHODS During the last 2 years, patients referred for pancreatic surgery and without history of diabetes underwent a prospective preoperative screening with an oral glucose tolerance test (OGTT) and determination of the glycated haemoglobin level (HbA1c). The American Diabetes Association's criteria for diabetes and pre-diabetes were used. Beta-cell function and insulin sensitivity were calculated using HOMA2 indices. Impact on surgical policy has been scored. RESULTS 99 patients were screened, 25 had a history of diabetes. The other 74 underwent an OGTT and HbA1c determination. Only 29.7% (22/74) had a normal glucose metabolism, while 8.1% (6/74) had impaired fasting glucose, 21.6% (16/74) had impaired glucose tolerance, 6.7% (5/74) had a combination of both, and 33.8% (25/74) had undiagnosed diabetes. In 15.2% (15/99) of the patients, this preoperative assessment had an impact on surgical policy. CONCLUSIONS 77.7% of patients referred for pancreatic surgery had some degree of (pre-)diabetes. In 70.3% of patients without a history of diabetes, these disturbances in glucose metabolism are a new finding. Physicians involved in pancreatic surgery should be aware of the frequently undiagnosed (pre-)diabetes and actively check for it. This prevalence is underestimated.

Abstract
OBJECTIVE A craniopharyngioma (CP) is a benign tumor commonly considered to originate from the pituitary stalk. However, it is still controversial as to whether the pituitary stalk should be maintained after microsurgery to resect the tumor despite its own physiological function of the pituitary stalk. In this study, meta-analysis was conducted to evaluate the influence of the pituitary stalk resection on endocrine function and tumor recurrence rate. METHODS The relevant publications were identified by searching databases including Pubmed, Embase, Medline, and Web of Science. The extracted data were used as the basis for the meta-analysis by the RevMan 5.2 software program. RESULTS Seven articles were selected, including 420 clinical cases. The meta-analysis showed that retaining the pituitary stalk might reduce the occurrence rate of diabetes insipidus (OR=0.21, 95%CI=0.10, 0.46, P=0.0001) and the risk of potential impairment of anterior pituitary function (OR=0.04, 95%CI=0.01, 0.13, P<0.0001). However, there was no significant relationship between craniopharyngioma recurrence and pituitary stalk treatment (i.e., preservation or resection) (OR=1.40, 95%CI=0.59, 3.34, P=0.45). CONCLUSION The maintenance of the pituitary stalk may reduce the alterations in endocrine function and the occurrence of diabetes insipidus. However, it is not likely to enhance the recurrence rate of craniopharyngiomas.

Abstract
Clinical interventions to preserve fertility and restore hormone levels in female patients with therapy-induced ovarian failure are insufficient, particularly for pediatric cancer patients. Laparoscopic isolation of cortical ovarian tissue followed by cryopreservation with subsequent autotransplantation has temporarily restored fertility in at least 27 women who survived cancer, and aided in pubertal transition for one pediatric patient. However, reintroducing cancer cells through ovarian transplantation has been a major concern. Decellularization is a process of removing cellular material, while maintaining the organ skeleton of extracellular matrices (ECM). The ECM that remains could be stripped of cancer cells and reseeded with healthy ovarian cells. We tested whether a decellularized ovarian scaffold could be created, recellularized and transplanted to initiate puberty in mice. Bovine and human ovaries were decellularized, and the ovarian skeleton microstructures were characterized. Primary ovarian cells seeded onto decellularized scaffolds produced estradiol in vitro. Moreover, the recellularized grafts initiated puberty in mice that had been ovariectomized, providing data that could be used to drive future human transplants and have broader implications on the bioengineering of other organs with endocrine function.

Abstract
BACKGROUND A cancer diagnosis leads to increased psychological and emotional distress. However, in the aftermath of a traumatic event, such as being diagnosed with breast cancer, an individual may also experience beneficial changes in life perspective, relationships with others, and more. These changes are collectively known as posttraumatic growth (PTG). Studies have demonstrated that cortisol levels have been linked with cancer survival, yet an investigation of the relationship between PTG and cortisol has yet to be conducted among cancer patients. METHODS The relationship of PTG to cortisol levels was examined among 99 metastatic breast cancer patients. RESULTS We found a significant correlation between PTG and diurnal cortisol slope (Spearman's rho=-0.21, p<0.05), indicating a link between positive psychological changes and healthier endocrine functioning in cancer patients. CONCLUSIONS PTG in response to the stress of cancer was related to more normal (i.e., steeper) diurnal cortisol patterns. Longitudinal studies are recommended to investigate these mechanisms in relationship to cancer survival.

Abstract
This study was designed to evaluate the detrimental effect of atrazine (ATR) on germinal epitheliums (GE) cytoplasmic carbohydrate (CH) and unsaturated fatty acids (UFA) ratio and to clarify the effect of ATR on serum levels of FSH, LH, testosterone and inhibin-B (INH-B). The impact of ATR exposure on total antioxidant capacity (TAC), sperm DNA packing and integrity were also investigated. Seventy two Wistar rats were used. The rats in control group received vehicle and the animals in test groups received 100, 200 and 300 mg kg(-1) BW of ATR orally on daily bases for 12, 24 and 48 days. In ATR-received groups the spermatogenesis cell were presented with dense reactive sites for lipidophilic staining associated with faint cytoplasmic CH accumulation. Dissociated germinal epithelium, negative tubular and repopulation indexes were manifested. The serum levels of testosterone, FSH, LH and INH-B decreased by 85% after 48 days exposure to high dose of ATR. TAC was reduced in a time- and dose-dependent manner. The sperm DNA damage was marked in animals which exposed to high dose of ATR (72.50 ± 2.25%) and the percentage of nuclear immature sperm increased up to 83.40 ± 0.89%. In conclusion, ATR not only induced its detrimental effect on the endocrine function of the testes and pituitary gland but also affected the cytoplasmic CH ratio and consequently leads to inadequate energy supplement in spermatogenesis cells. Therefore the imbalanced oxidative stress occurs in testicular tissue, which in turn enhances the sperm DNA disintegrity and nuclear immaturity.

Abstract
The spleen could be considered a neglected organ. To date, it has been deemed an ancillary organ in portal hypertension or an organ localization in lymphoproliferative diseases, even though it has had significant attention in infectious diseases for some time. Now, it is thought to be central in regulating the immune system, a metabolic asset and involved in endocrine function with regard to nonalcoholic fatty liver disease. The main mechanisms involved in this complex network will be critically discussed in this article.

Abstract
AIM: To evaluate long-term endocrine and exocrine pancreatic function, quality of life and health care costs after mild acute pancreatitis and severe acute pancreatitis (SAP).
METHODS: Patients prospectively included in 2001-2005 were followed-up after 42 (36-53) mo. Pancreatic function was evaluated with laboratory tests, the oral glucose tolerance test (OGTT), fecal elastase-1 and a questionnaire. Short Form (SF)-36, was completed.
RESULTS: Fourteen patients with a history of SAP and 26 with mild acute pancreatitis were included. Plasma glucose after OGTT was higher after SAP (9.2 mmol/L vs 7.0 mmol/L, P = 0.044). Diabetes mellitus or impaired glucose tolerance in fasting plasma glucose and/or 120 min plasma glucose were more common in SAP patients (11/14 vs 11/25, P = 0.037). Sick leave, time until the patients could take up recreational activities and time until they had recovered were all longer after SAP (P < 0.001). No significant differences in SF-36 were seen between the groups, or when comparing with age and gender matched reference groups. Total hospital costs, including primary care, follow-up and treatment of complications, were higher after SAP (median €16 572 vs€5000, P < 0.001).
CONCLUSION: Endocrine pancreatic function was affected, especially after severe disease. SAP requires greater resource use with long recovery, but most patients regained a good quality of life.

Abstract
Resting levels of testosterone, luteinising hormone, cortisol, prolactin, and the testosterone/cortisol ratio were studied in a group of endurance athletes before and throughout a high intensity-volume phase of their yearly training cycles. During this period four athletes developed overtraining characteristics. These subjects were physically matched with control subjects conducting comparable training but exhibiting no overtraining symptoms. Hormonal comparisons between the groups revealed no significant differences existed prior to beginning the intensive training; nor did the hormonal levels of the control subjects alter significantly (P>0.05) due to the training. The overtrained subjects, however, did have a significant (P<0.01) decline in testosterone (6.8±1.0 to 4.4±1.0 ng/ml; MEAN ± SE). Furthermore, prolactin was found to significantly (P<0.05) elevate in the overtrained subjects (8.1±2.0 to 13.2±1.1. ng/ml), while the testosterone/cortisol ratio showed a significant (P<0.005) decline (0.83±0.26 to 0.36±0.08). No other significant changes were noted. These findings support the theory that the overtraining syndrome in athletes may represent a neuroendocrine dysfunction.
