Vitamin D, Parathyroid Hormone, Insulin Sensitivity and Islet β-Cell Secretory Function in Diabetic Patients from South Kivu in the Democratic Republic of Congo: Cross-Sectional Study

Background: The role of vitamin D and parathyroid hormone in the metabolic profile of type 2 diabetes mellitus in sub-Saharan Africa has not been adequately assessed. The aim of this study was to determine the prevalence of low vitamin D level and secondary hyperparathyroidism and their association with insulin sensitivity and β-cell secretory function among Congolese type 2 diabetics. Methodology: Fasting glycaemia, fasting insulin, 25OH D3 and human parathyroid hormone (hPTH) were measured in one hundred and eighty-four type 2 diabetic patients followed as outpatients in South Kivu. Levels of 25OH D3 65 pg/ml defined low vitamin D and elevated parathyroid hormone levels, respectively. The HOMA model was used to measure insulin sensitivity and β-cell secretory function. Results: Medians (IQR) were 25.3 (20.4 - 32.4) ng/ml for 25OH D3 and 53.7 (38.4 - 115.7) pg/ml for hPTH. 58.7% of diabetics had insulin resistance, 126 (68.5%) had low vitamin D and 80 (43.5%) had hyperparathyroidism. In multivariate analysis, hPTH (partial r = −0.28;p = 0.0002) and 25OH D3 (partial r = 0.16;p = 0.03) showed an independent association with insulin sensitivity after adjustment for body mass index and waist circumference. Finally, hPTH (partial r = 0.27;p = 0.0002) was the sole determinant of β-cell secretory function. Conclusions: This study confirms the high prevalence of low vitamin D level and secondary hyperparathyroidism and their association with insulin resistance and impaired islet β-cell secretory function among Congolese with type 2 diabetes mellitus. Vitamin D and calcium supplementation should be envisaged for cases of deficiency in this region.

Gut microbiota affects the estrus return of sows by regulating the metabolism of sex steroid hormones

Background Sex hormones play important roles in the estrus return of post-weaning sows.Previous studies have demonstrated a complex and bi-directional regulation between sex hormones and gut microbiota.However,the extent to which the gut microbiota affects estrus return of post-weaning sows is largely unknown.Results In this study,we first screened 207 fecal samples from well-phenotyped sows by 16S rRNA gene sequencing and identified significant associations between microbes and estrus return of post-weaning sows.Using metagenomic sequencing data from 85 fecal samples,we identified 37 bacterial species that were significantly associated with estrus return.Normally returning sows were characterized by increased abundances of L.reuteri and P.copri and decreased abundances of B.fragilis,S.suis,and B.pseudolongum.The changes in gut microbial composition significantly altered the functional capacity of steroid hormone biosynthesis in the gut microbiome.The results were confirmed in a validation cohort.Significant changes in sex steroid hormones and related compounds were found between normal and non-return sows via metabolome analysis.An integrated analysis of differential bacterial species,metagenome,and fecal metabolome provided evidence that normal return-associated bacterial species L.reuteri and Prevotella spp.participated in the degradation of pregnenolone,progesterone,and testosterone,thereby promoting estrogen biosynthesis.Furthermore,the microbial metabolites related to sow energy and nutrient supply or metabolic disorders also showed relationships with sow estrus return.Conclusions An integrated analysis of differentially abundant bacterial species,metagenome,and fecal metabolome revealed the involvement of L.reuteri and Prevotella spp.in sow estrus return.These findings provide deep insight into the role of gut microbiota in the estrus return of post-weaning sows and the complex cross-talk between gut microbiota and sex hormones,suggesting that the manipulation of the gut microbiota could be an effective strategy to improve sow estrus return after weaning.

The Effects of Age and Ejaculatory Abstinence on Semen Quality and Reproductive Hormones in Africa and the Middle East

The aim of this study was to retrospectively evaluate the effects of male age and ejaculatory abstinence on semen parameters and reproductive hormones among men residing in Africa and the Middle East. A total of 70,142 semen analysis results were analysed and grouped according to the age intervals (16 - 20, 21 - 30, 31 - 40, 41 - 50, 51 - 60, >60) and ejaculatory abstinence (<2 days, 2 - 5 days and >5 days). Semen parameters i.e. volume, concentration, progressive motility, total progressively motile count, morphology, total normal sperm count, DNA fragmentation, viability, sORP, normed sORP were specifically evaluated. Additionally, for each age interval, reproductive hormones i.e. estradiol, luteinizing hormone, follicle stimulating hormone, testosterone and prolactin were evaluated. Semen volume, total progressively motile count, sperm morphology and total normal sperm count constantly decrease significantly after the age of 30 years. Sperm concentration started declining significantly after the age of 50 years. There was a constant age- related increase in number of spermatozoa with damaged DNA. sORP constantly increased up to 60 years. Furthermore, constantage-related decreases in FSH, serum testosterone and prolact in were observed from patients aged between 16 years and 60 years. Semen volume, sperm concentration, progressive motility and normal morphology were significantly higher in patients having > 5 days of abstinence. Patients having > 5 days of abstinence had the lowest normed sORP. Male age significantly affects sperm parameters and reproductive hormones in fertile and infertile men residing in Africa and the Middle East. Prolonged abstinence days provides better semen quality.

Growth hormone promotes the reconstruction of injured axons in the hypothalamo-neurohypophyseal system

Previous studies have shown that growth hormone can regulate hypothalamic energy metabolism, stress, and hormone release. Therefore, growth hormone has great potential for treating hypothalamic injury. In this study, we established a specific hypothalamic axon injury model by inducing hypothalamic pituitary stalk electric lesions in male mice. We then treated mice by intraperitoneal administration of growth hormone. Our results showed that growth hormone increased the expression of insulin-like growth factor 1 and its receptors, and promoted the survival of hypothalamic neurons, axonal regeneration, and vascular reconstruction from the median eminence through the posterior pituitary. Altogether, this alleviated hypothalamic injury-caused central diabetes insipidus and anxiety. These results suggest that growth hormone can promote axonal reconstruction after hypothalamic injury by regulating the growth hormone-insulin-like growth factor 1 axis.

Iodine Nutrition, Thyroid-stimulating Hormone, and Related Factors of Postpartum Women from three Different Areas in China: A Cross-sectional Survey

Objective Studies on the relationship between iodine,vitamin A(VA),and vitamin D(VD)and thyroid function are limited.This study aimed to analyze iodine and thyroid-stimulating hormone(TSH)status and their possible relationships with VA,VD,and other factors in postpartum women.Methods A total of 1,311 mothers(896 lactating and 415 non-lactating)from Hebei,Zhejiang,and Guangxi provinces were included in this study.The urinary iodine concentration(UIC),TSH,VA,and VD were measured.Results The median UIC of total and lactating participants were 142.00µg/L and 139.95µg/L,respectively.The median TSH,VA,and VD levels in all the participants were 1.89 mIU/L,0.44μg/mL,and 24.04 ng/mL,respectively.No differences in the UIC were found between lactating and non-lactating mothers.UIC and TSH levels were significantly different among the three provinces.The rural UIC was higher than the urban UIC.Obese mothers had a higher UIC and a higher prevalence of excessive TSH.Higher UICs and TSHs levels were observed in both the VD deficiency and insufficiency groups than in the VD-sufficient group.After adjustment,no linear correlation was observed between UIC and VA/VD.No interaction was found between vitamins A/D and UIC on TSH levels.Conclusion The mothers in the present study had no iodine deficiency.Region,area type,BMI,and VD may be related to the iodine status or TSH levels.

Unraveling the gut-brain axis:the impact of steroid hormones and nutrition on Parkinson's disease

This comprehensive review explores the intricate relationship between nutrition,the gut microbiome,steroid hormones,and Parkinson's disease within the context of the gut-brain axis.The gut-brain axis plays a pivotal role in neurodegenerative diseases like Parkinson's disease,encompassing diverse components such as the gut microbiota,immune system,metabolism,and neural pathways.The gut microbiome,profoundly influenced by dietary factors,emerges as a key player.Nutrition during the first 1000 days of life shapes the gut microbiota composition,influencing immune responses and impacting both child development and adult health.High-fat,high-sugar diets can disrupt this delicate balance,contributing to inflammation and immune dysfunction.Exploring nutritional strategies,the Mediterranean diet's anti-inflammatory and antioxidant properties show promise in reducing Parkinson's disease risk.Microbiome-targeted dietary approaches and the ketogenic diet hold the potential in improving brain disorders.Beyond nutrition,emerging research uncovers potential interactions between steroid hormones,nutrition,and Parkinson's disease.Progesterone,with its anti-inflammatory properties and presence in the nervous system,offers a novel option for Parkinson's disease therapy.Its ability to enhance neuroprotection within the enteric nervous system presents exciting prospects.The review addresses the hypothesis thatα-synuclein aggregates originate from the gut and may enter the brain via the vagus nerve.Gastrointestinal symptoms preceding motor symptoms support this hypothesis.Dysfunctional gut-brain signaling during gut dysbiosis contributes to inflammation and neurotransmitter imbalances,emphasizing the potential of microbiota-based interventions.In summary,this review uncovers the complex web of interactions between nutrition,the gut microbiome,steroid hormones,and Parkinson's disease within the gut-brain axis framework.Understanding these connections not only offers novel therapeutic insights but also illuminates the origins of neurodegenerative diseases such as Parkinson's disease.

Growth hormone improves insulin resistance in visceral adipose tissue after duodenal-jejunal bypass by regulating adiponectin secretion

BACKGROUND The mechanism of improvement of type 2 diabetes after duodenal-jejunal bypass(DJB)surgery is not clear.AIM To study the morphological and functional changes in adipose tissue after DJB and explore the potential mechanisms contributing to postoperative insulin sensitivity improvement of adipose tissue in a diabetic male rat model.METHODS DJB and sham surgery was performed in a-high-fat-diet/streptozotocin-induced diabetic rat model.All adipose tissue was weighed and observed under microscope.Use inguinal fat to represent subcutaneous adipose tissue(SAT)and mesangial fat to represent visceral adipose tissue.RNA-sequencing was utilized to evaluate gene expression alterations adipocytes.The hematoxylin and eosin staining,reverse transcription-quantitative polymerase chain reaction,western blot,and enzyme-linked immunosorbent assay were used to study the changes.Insulin resistance was evaluated by immunofluorescence.RESULTS After DJB,whole body blood glucose metabolism and insulin sensitivity in adipose tissue improved.Fat cell volume in both visceral adipose tissue(VAT)and SAT increased.Compared to SAT,VAT showed more significantly functional alterations after DJB and KEGG analysis indicated growth hormone(GH)pathway and downstream adiponectin secretion were involved in metabolic regulation.The circulating GH and adiponectin levels and GH receptor and adiponectin levels in VAT increased.Cytological experiment showed that GH stimulated adiponectin secretion and improve insulin sensitivity.CONCLUSION GH improves insulin resistance in VAT in male diabetic rats after receiving DJB,possibly by increasing adiponectin secretion.

Metformin:A promising clinical therapeutical approach for BPH treatment via inhibiting dysregulated steroid hormones-induced prostatic epithelial cells proliferation

The occurrence of benign prostate hyperplasia(BPH)was related to disrupted sex steroid hormones,and metformin(Met)had a clinical response to sex steroid hormone-related gynaecological disease.However,whether Met exerts an antiproliferative effect on BPH via sex steroid hormones remains unclear.Here,our clinical study showed that along with prostatic epithelial cell(PEC)proliferation,sex steroid hormones were dysregulated in the serum and prostate of BPH patients.As the major contributor to dysregulated sex steroid hormones,elevated dihydrotestosterone(DHT)had a significant positive relationship with the clinical characteristics of BPH patients.Activation of adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK)by Met restored dysregulated sex steroid hormone homeostasis and exerted antiproliferative effects against DHT-induced proliferation by inhibiting the formation of androgen receptor(AR)-mediated Yes-associated protein(YAP1)-TEA domain transcription factor(TEAD4)heterodimers.Met’s anti-proliferative effects were blocked by AMPK inhibitor or YAP1 overexpression in DHT-cultured BPH-1 cells.Our findings indicated that Met would be a promising clinical therapeutic approach for BPH by inhibiting dysregulated steroid hormone-induced PEC proliferation.

Evaluation of Serum Anti-Müllerian Hormone (AMH) Values for 28,016 Bulgarian Women: Prognostic Statistical Model of Age Specific AMH Declining

The present study aims to establish a relationship between serum AMH levels and age in a large group of women living in Bulgaria, as well as to establish reference age-specific AMH levels in women that would serve as an initial estimate of ovarian age. A total of 28,016 women on the territory of the Republic of Bulgaria were tested for serum AMH levels with a median age of 37.0 years (interquartile range 32.0 to 41.0). For women aged 20 - 29 years, the Bulgarian population has relatively high median levels of AMH, similar to women of Asian origin. For women aged 30 - 34 years, our results are comparable to those of women living in Western Europe. For women aged 35 - 39 years, our results are comparable to those of women living in the territory of India and Kenya. For women aged 40 - 44 years, our results were lower than those for women from the Western European and Chinese populations, close to the Indian and higher than Korean and Kenya populations, respectively. Our results for women of Bulgarian origin are also comparable to US Latina women at age 30, 35 and 40 ages. On the base on constructed a statistical model to predicting the decline in AMH levels at different ages, we found non-linear structure of AMH decline for the low AMH 3.5) the dependence of the decline of AMH on age was confirmed as linear. In conclusion, we evaluated the serum level of AMH in Bulgarian women and established age-specific AMH percentile reference values based on a large representative sample. We have developed a prognostic statistical model that can facilitate the application of AMH in clinical practice and the prediction of reproductive capacity and population health.

Post Thyroidectomy Assessment of Intact Parathyroid Hormone for Early Prediction of Hypocalcaemia

Background: As the half-life of intact parathyroid hormone (iPTH) is very low, it reflects parathyroid insufficiency within minutes to hours after total thyroidectomy. Therefore, iPTH level assessment in the postoperative period can be used to predict the development of hypocalcaemia. The optimal time point to measure serum iPTH is important for the accurate prediction of hypocalcaemia. Aim: This paper aims to evaluate the ability of iPTH as an early predictive marker of hypocalcaemia and determine which time iPTH is more able to predict postoperative hypocalcaemia. Method: This prospective observational study was conducted in the Department of Otolaryngology-Head & Neck Surgery, BSMMU, Dhaka, from July 2020 to December 2021, with 67 patients who underwent total thyroidectomy. iPTH levels were measured on the day before the operation and at 1 hour, 4 hours, and 24 hours after the operation. S.calcium levels were measured on the day before the operation and 1st postoperative day. All the data were compiled and sorted properly and were analyzed statistically. Results: Postoperative hypocalcaemia developed in 18 cases, with an incidence of 26.9%. Pearson correlation showed a significant correlation between postoperative iPTH at 1 hr, 4 h, and 24 hr with 1st postoperative calcium value. The Receiver operating characteristic (ROC) curve was processed for the postoperative iPTH at 1 hr, 4 h, and 24 hr. The sensitivity, specificity, cut-off value, and mean AUC found 93.9%, 94.4%, ≤14.0, 0.988;95.9%, 94.4%, ≤09.5, 0.993 and 91.8%, 94.4%, ≤11.0, 0.993 respectively. Conclusion: iPTH can be used as an early predictor of post-thy-roidectomy hypocalcaemia. 4 hr iPTH showed more sensitivity and specificity for a cut-off value near the laboratory reference range.

Does the use of double hormone replacement therapy for trauma patient organ donors improve organ recovery for transplant

BACKGROUND With an ongoing demand for transplantable organs,optimization of donor management protocols,specifically in trauma populations,is important for obta-ining a high yield of viable organs per patient.Endocrine management of brain-dead potential organ donors(BPODs)is controversial,leading to heterogeneous clinical management approaches.Previous studies have shown that when levo-thyroxine was combined with other treatments,including steroids,vasopressin,and insulin,BPODs had better organ recovery and survival outcomes were increased for transplant recipients.AIM To determine if levothyroxine use in combination with steroids in BPODs increased the number of organs donated in trauma patients.METHODS A retrospective review of adult BPODs from a single level 1 trauma center over ten years was performed.Exclusion criteria included patients who were not solid organ donors,patients who were not declared brain dead(donation after circulatory death),and patients who did not receive steroids in their hospital course.Levothyroxine and steroid administration,the number of organs donated,the types of organs donated,and demographic information were recorded.Univariate analyses were performed with P<0.05 considered to be statistically significant.RESULTS A total of 88 patients met inclusion criteria,69(78%)of whom received levothyroxine and steroids(ST/LT group)vs 19(22%)receiving steroids without levothyroxine(ST group).No differences were observed between the groups for gender,race,pertinent injury factors,age,or other hormone therapies used(P>0.05).In the ST/LT group,68.1%(n=47)donated a high yield(3-5)of organ types per donor compared to 42.1%(n=8)in the ST group(P=0.038).There was no difference in the total number of organ types donated between the groups(P=0.068).CONCLUSION This study suggests that combining levothyroxine and steroid administration increases high-yield organ donation per donor in BPODs in the trauma patient population.Limitations to this study include the retrospective design and the relatively small number of organ donors who met inclusion criteria.This study is unique in that it mitigates steroid administration as a confounding variable and focuses specifically on the adjunctive use of levothyroxine.

Rikkunshito increases peripheral incretin-hormone levels in humans and rats

BACKGROUND It was reported that rikkunshito(TJ-43)improved the cisplatin-induced decreases in the active form of ghrelin in plasma;however,other effects on gastrointestinal hormones have not been investigated.AIM To investigate the effects of TJ-43 on peripheral levels of incretin hormones,including gastric inhibitory polypeptide(GIP)and glucagon-like polypeptide-1(GLP-1),in humans and rats.METHODS Patients were divided into two groups,namely patients who received TJ-43 immediately following surgery[TJ-43(+)group]and those who received TJ-43 on postoperative day 21[TJ-43(-)group],and the plasma levels of active GIP and active GLP-1 were assessed.In animal experiments,rats were treated with TJ-43[rat(r)TJ-43(+)group]or without[rTJ-43(−)group]by gavage for 4 wk,and the plasma active GIP and active GLP-1 levels were measured.The expression of incretin hormones in the gastrointestinal tract and insulin in the pancreas were investigated by immunohistochemistry.Furthermore,the cyclic adenosine monophosphate activities were assessed in pancreatic tissues from rats treated with or without TJ-43 in vivo,and the blood glucose levels and plasma insulin levels were measured in rats treated with or without TJ-43 in oral glucose tolerance tests.RESULTS In humans,the active incretin hormone levels increased,and values were significantly greater in the TJ-43(+)group compared those in the TJ-43(-)group.In rats,the plasma active incretin levels significantly increased in the rTJ-43(+)group compared with those in the rTJ-43(-)group.GIP and GLP-1 expressions were enhanced by TJ-43 treatment.Moreover,plasma insulin levels increased and blood glucose levels were blunted in the rTJ-43(+)group.CONCLUSION The results show that TJ-43 may be beneficial for patients who undergo pancreatic surgery.

目的:探究基础黄体生成素(bLH)及不同黄体生成素/卵泡刺激素(LH/FSH)比值水平对多囊卵巢综合征(PCOS)患者体外受精或卵胞浆内单精子注射(IVF/ICSI)妊娠结局的影响。方法:选择2013年7月至2020年1月在南京医科大学第一附属医院生殖医学科首次行促性腺激素释放激素(GnRH)拮抗剂灵活方案促排卵,接受IVF/ICSI治疗的424例PCOS患者的临床资料进行回顾性分析。按照bLH水平不同分为正常bLH组(LH≤10 U/L,316例)和高bLH组(LH>10 U/L,108例);同时根据LH/FSH比值水平不同分为低比值组(LH/FSH≤1,227例)、中比值组(1<LH/FSH<2,142例)、高比值组(LH/FSH≥2,55例)。分析比较各组患者一般情况、促排卵情况及妊娠结局的差异,并采用二元Logistic回归分析影响活产的相关因素。结果:①高bLH组基础FSH和抗苗勒管激素(AMH)较正常bLH组高,差异有统计学意义(P<0.05)。在促排卵情况方面,高bLH组使用拮抗剂总天数长于正常组,但获卵数和绒促性素(HCG)日子宫内膜厚度小于正常bLH组,差异有统计学意义(P<0.05)。两组患者妊娠结局相关指标比较,差异无统计学意义(P>0.05)。②不同LH/FSH比值组患者比较,高比值组AMH和窦卵泡数(AFC)高于其他两组,差异有统计学意义(P<0.05)。在促排卵情况方面,高比值组获卵数、移植胚胎数、HCG日子宫内膜厚度均低于其他两组,差异有统计学意义(P<0.05)。3组患者妊娠结局相关指标比较,差异无统计学意义(P>0.05)。③二元Logistic回归分析显示活产与bLH、LH/FSH比值无关(P>0.05),与移植胚胎数有关(P<0.05)。结论:bLH水平和LH/FSH值升高可能会影响PCOS患者促排卵结果(如获卵数和HCG日子宫内膜厚度等),但与辅助生殖的活产率未见显著相关性。

应用FSH及HCG药物对乏情后备母猪及断奶母猪的疗效试验

为了探索在母猪定时输精技术中激素类药物的使用对于母猪生产成绩的影响,该文应用促卵泡生成素(FSH)及绒毛膜促性腺激素(HCG)药物对乏情后备母猪及断奶母猪进行疗效试验。试验共分2个组,A组为药物处理组,B组为空白对照组,A组给予断奶后母猪或乏情后备母猪烯丙孕素饲喂结束后的24h、96h分别肌注FSH药物与HCG药物;B组仅饲喂烯丙孕素,然后进行定时输精。配种结束后在同一条件下饲养管理,最终观察母猪的受胎情况和分娩情况。试验结果表明,激素处理组的乏情后备母猪的配种受胎率提高3.26%,窝均总仔提高0.35头,窝均健仔提高0.13头;激素处理组的断奶母猪配种率提高7.14%,配种受胎率提高2.86%,窝均总仔提高1.18头,窝均健仔提高1头。从本试验看,乏情后备母猪及断奶母猪使用FSH与HCG处理,可获得好的生产成绩,该技术可在种猪场推广应用。
