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.

Correlation analysis of serum thyroglobulin,thyroid-stimulating hormone levels,and thyroid-cancer risk in thyroid nodule surgery

BACKGROUND Thyroglobulin(Tg)is one of the markers of thyroid cancer,and its concentration may be elevated in patients with malignant thyroid tumors.Thyroid-stimulating hormone(TSH)is secreted by the pituitary gland,which has a significant impact on thyroid gland function.Excessively high or low TSH levels may be associated with an increased risk of thyroid cancer.Thus,in-depth studies on the association of serum Tg and TSH levels with thyroid cancer risk in patients with thyroid nodules are warranted.This can help determine whether Tg and TSH levels can predict the degree of malignancy of thyroid nodules,which can in turn guide doctors in making accurate diagnoses and treatment decisions.Furthermore,such studies can provide more accurate diagnostic methods for thyroid nodules and help patients become aware of the presence of thyroid cancer as early as possible,thereby improving the success rate of treatment and prognosis.AIM To investigate the association of serum Tg and TSH levels with the risk of thyroid cancer in patients undergoing thyroid nodule surgery.METHODS The clinical data and laboratory examination results of 130 patients who underwent thyroid nodule surgery were retrospectively analyzed.Furthermore,their preoperative serum Tg and TSH levels were recorded.Histopathological examination conducted during follow-up revealed the presence of thyroid cancer.Correlation analysis were used to analyze the association of Tg and TSH levels with the risk of thyroid cancer.RESULTS Of the 130 patients,60 were diagnosed with thyroid cancer.Statistical analysis revealed a significant positive correlation between serum Tg levels and the risk of thyroid cancer(P<0.05).This suggests that high serum Tg levels are associated with an increased risk of thyroid cancer.However,no significant correlation was observed between serum TSH levels and the risk of thyroid cancer(P>0.05).CONCLUSION In patients who underwent thyroid nodule surgery,serum Tg levels exhibited a significant correlation with the risk of thyroid cancer but serum TSH levels did not.These findings suggest that serum Tg can serve as an important biomarker for assessing the risk of thyroid cancer in these patients.

Clinical Value of Serum Anti-Mullerian Hormone and Inhibin B in Prediction of Ovarian Response in Patients with Polycystic Ovary Syndrome

The present study aimed to investigate the clinical value of serum anti-mullerian hormone（AMH） and inhibin B（INHB） in predicting the ovarian response of patients with polycystic ovary syndrome（PCOS）. A total of 120 PCOS patients were enrolled and divided into three groups in terms of the ovarian response： a low-response group（n=36）, a normal-response group（n=44）, and a high-response group（n=40）. The serum AMH and INHB levels were measured by enzyme-linked immunosorbent assay（ELISA）. The follicle stimulating hormone（FSH）, luteinizing hormone（LH）, and estradiol（E2） levels were determined by chemiluminescence microparticle immunoassay. The correlation of the serum AMH and INHB levels with other indicators was analyzed. A receiver operating characteristic（ROC） curve was established to analyze the prediction of ovarian response by AMH and INHB. The results showed that there were significant differences in age, body mass index（BMI）, FSH, total gonadotropin-releasing hormone（Gn RH）, LH, E2, and antral follicle counts（AFCs） between the groups（P〈0.05）. The serum AMH and INHB levels were increased significantly with the ovarian response of PCOS patients increasing（P〈0.05）. The serum AMH and INHB levels were negatively correlated with the age, BMI, FSH level, Gn, and E2 levels（P〈0.05）. They were positively correlated with the LH levels and AFCs（P〈0.05）. ROC curve analysis of serum AMH and INHB in prediction of a low ovarian response showed that the area under the ROC curve（AUC） value of the serum AMH level was 0.817, with a cut-off value of 1.29 ng/m L. The sensitivity and specificity were 71.2% and 79.6%, respectively. The AUC value of serum INHB was 0.674, with a cut-off value of 38.65 ng/m L, and the sensitivity and specificity were 50.7% and 74.5%, respectively. ROC curve analysis showed when the serum AMH and INHB levels were used to predict a high ovarian response, the AUC value of the serum AMH level was 0.742, with a cut-off value of 2.84 ng/m L, and the sensitivity and specificity were 72.7% and 65.9%, respectively; the AUC value of the serum INHB level was 0.551 with a cut-off of 45.76 ng/m L, and the sensitivity and specificity were 76.3% and 40.2%, respectively. It was suggested the serum AMH and INHB levels have high clinical value in predicting the ovarian response of PCOS patients.

Anti-Mullerian Hormone and Follicle Counts as Predictors of Superovulatory Response and Embryo Production in Beef Cattle

This study evaluated Anti-Mullerian hormone (AMH) and/or follicle counts as predictors of subsequent superovulatory response and embryo production in 79 beef cows. Before superovulation, 3 to 5 mm follicles presented on the ovaries of donor cows were counted, and blood was collected for measure of serum AMH. Across cows, serum AMH ranged from 0.013 to 0.898 ng/mL, with a mean of 0.293 ng/mL. The distribution of both AMH concentrations and follicle counts were divided into quartiles (AMH Q1 through Q4, with Q1 the lowest and Q4 the highest) for analysis. Donor cows in AMH Q4 had a greater (P < 0.001) number of 3 to 5 mm follicles at the start of superovulation than did donors in either Q1 or Q2. At embryo collection, cows in AMH Q3 and 4 had more (P < 0.001) palpable corpora lutea (CL) than cows in AMH Q1. The mean number of embryos recovered from donor cows in AMH Q4 was greater (P < 0.001) than those recovered from cows in either AMH Q1 or 2, but similar to that of AMH Q3. Analysis indicated that AMH was positively correlated (P < 0.001) with mean follicles (r = 0.458), CL (r = 0.452) and embryos recovered (r = 0.430). Donor cows with higher follicle counts (F Q3 and 4) at the start of superovulation had more (P < 0.001) palpable CL at embryo collection than donor cows in F Q1 or 2. More (P < 0.001) embryos were recovered from cows with the highest follicle counts (F Q4) as compared with cows having lower (F Q1 and 2) follicle counts. Results confirm that relative AMH concentration was positively correlated with number of small antral follicles in the ovaries of cows;both AMH measure and antral follicle counts might be used to predict subsequent superovulatory response in beef cows.

The effects of consumption of raw garlic on serum lipid level, blood sugar and a number of effective hormones on lipid and sugar metabolism in hyperglycemic and/or hyperlipidemic individuals ——Benefit of raw garlic consumption

Diabetes mellitus is one of the worldwide largest growing metabolic diseases. In this study the effects of consumption of raw garlic on serum lipid level, blood sugar and a number of effective hormones on lipid and sugar metabolism (thyroid hormones and insulin) in individuals either with high level of blood sugar or lipid were investigated. Eighty five volunteers having following clinical history enrolled in the study: Group 1: having blood sugar more than 126 mg/dl (30 vo-lunteers);Group 2: having cholesterol higher than 245 mg/dl (30 volunteers);Group 3: having blood sugar over 126 mg/dl and cholesterol more than 245 mg/dl (25 volunteers). In group 1, there wasn’t a sig-nificant differences between biochemical factors be-fore and after garlic consumption, whereas, in the second group after 6 weeks of garlic consumption a decline in cholesterol (P < 0.001), FBS and TG (P < 0.01) was observed but HDL-C (P < 0.001) was in-creased. Six weeks after termination of garlic con-sumption, cholesterol (P < 0.001), FBS and TG (P < 0.05) were in- creased and HDL-C (P < 0.01) was de-creased. In the third group, total cholesterol (P < 0.001), FBS (P < 0.01) and HbA1c decreased while HDL-C was in- creased. Other factors, including thy-roid hormones (T3, T4), TSH and insulin showed no significant alte- ration. In conclusion our results shown that raw garlic consumption can reduce the FBS and Lipid in hyperglycemic and/or hyperlipidemic individuals.

Use of Anti-Mullerian Hormone (AMH) for Testing of Ovarian Reserve: A Survey of Fifteen (15) Fertility Centres in Ghana

Anti-Mullerian Hormone (AMH) is a dimeric glycoprotein with a molecular weight of 140 kD, encoded by a gene on the short arm of chromosome and a member of the transforming growth factor-beta (TGF-β) superfamily. The expression of AMH is markedly different in males and females, both in concentration and temporality. In males, Sertoli cells maintain a high concentration of AMH in utero which peaks shortly after birth and then drops precipitously at puberty. In females, granulosa cells produce very low levels of AMH in utero followed by a transient spike in the neonatal period. Concentrations of the hormone then rise steadily through adolescence to a peak in the mid-twenties and subsequently decline until becoming undetectable in menopause. The study aimed to understand how Clinicians and Clinical Embryologists used anti-mullerian hormone (AMH) test to assess ovarian reserve, direct patient selection and treatment regimens and guide in vitro fertilization (IVF) cycle management in all registered fertility hospitals in a West African country, Ghana. A web-based survey (questionnaire) using google forms was performed to solicit responses from all IVF hospitals that are registered with the Fertility Society of Ghana (FERSOG). This questionnaire consisted of fifteen (15) broader questions, ten (10) of which assessed the clinics’ use of AMH. Responses were screened for quality to verify that only one (1) survey was completed by each IVF centre. The study was conducted during May and June 2020 at the In Vitro Fertilization (IVF) Department of the Airport Women’s Hospital (AWH) in Accra, Ghana. Results are reported as the proportion of IVF cycles represented by a particular answer choice. Survey responses were completed from 15 IVF centres, representing 2504 IVF cycles performed annually. A good majority (73.3%) [1835 IVF cycles] of the respondent IVF hospitals reported to use AMH as a first line test and 93.3% reported it as the best test for evaluating ovarian reserve. Another 66.7% reported that AMH results were extremely relevant to clinical practice. However, in contrast, for predicting live birth rate, 60% reported age as the best predictor in their practice. Overall, our results indicate that AMH is considered a first line test for assessing ovarian reserve and is relevant to the clinical practice of majority of Assisted Reproductive Technologies (ART) providers in Ghana.

Effect of daidzein on milk yield,components of milk and hormones in serum of dairy cows

Four Holstein dairy cows in the 7th month of late lactation were sampled, and self-control method was used. Daidzein was added to the concentrated feed at the dose of 10mg/kg during the treatment stage. Results showed that daidzein lessened the declining tendency of milk yield in late lactation and increased the milk yield to some extents. Lactoprotein was evidently increased (P<0.01), while milkfat was not affected evidently. The level of T4 in serum was evidently increased (P<0.05); the levels of GH, PRL, E2 and TSH in serum were prone to rising while T3 was prone to decreasing . It was concluded that daidzein could indirectly affect milk yield and components of milk by regulating the levels of intrinsic hormones.

Expression of anti-Mullerian hormone receptor on the appendix testis in connection with urological disorders

The female internal sex organs develop from the paramesonephric （Mullerian） duct. In male embryos, the regression of the Mullerian duct is caused by the anti-Mullerian hormone （AMH）, which plays an important role in the process of testicular descent. The physiological remnant of the Mullerian duct in males is the appendix testis （AT）. In our previous study, we presented evidence for the decreased incidence of AT in cryptorchidism with intraoperative surgery. In this report, the expression of the anti-Mullerian hormone receptor type 2 （AMHR2）, the specific receptor of AMH, on the AT was investigated in connection with different urological disorders, such as hernia inguinalis, torsion of AT, cysta epididymis, varicocele, hydrocele testis and various forms of undescended testis. The correlation between the age of the patients and the expression of the AMHR2 was also examined. Reverse transcriptase-polymerase chain reaction （RT-PCR） and immunohistochemistry were used to detect the receptor＇s mRNA and protein levels, respectively. We demonstrate that AMHR2 is expressed in the ATs. Additionally, the presence of this receptor was proven at the mRNA and protein levels. The expression pattern of the receptor correlated with neither the examined urological disorders nor the age of the patients; therefore, the function of the AT remains obscure.

Anti-Mullerian Hormone: Establishing the Ovarian Reserve Range with Age in Rivers State Women, Niger Delta Region of Nigeria

Background: The measurement of circulating anti-Mullerian hormone (AMH) in the plasma of adult women has been used as a tool in the assessment of ovarian reserve. This is based on its ability to reflect the number of growing follicles in the ovaries and knowing the level of AMH in a woman’s blood is generally a good indicator of her ovarian reserve and this can be achieved by making reference to a decision values. Objective: The purpose of this study was to measure the level of this hormone in normal, apparently healthy subjects in Rivers State, Nigeria with respect to age. The percentage of women, at their reproductive age with infertility problems in the state is in the increase and the essence was to establish a reference range for the hormone because of its clinical application in women fertility. Materials/method: A total of one thousand and sixty two apparently healthy women divided into four age groups were recruited for this study;this comprised of 300 each in age group of 20 - 30, 31 - 40, 41 - 50 respectively and 162 in 51 - 60 years age group from May 2014 to June 2017. They were randomly selected after filling a questionnaire form that has the information of age, tribe, last date of menses and whether on medication for any infertility problems. Excluded from the study were subjects identified with different endocrine dysfunction and/or on drugs for different types of anovulatory dysfunction. The Enzyme linked Immunoassay method was used in the measurement of the AMH. Results: The result from the measurement of plasma AMH levels showed a Mean ± SD value of 3.193 ± 0.943, 1.644 ± 0.691, 0.516 ± 0.276 and 0.135 ± 0.081 ng/ml respectively for the 1st, 2nd, 3rd and 4th age groups respectively. The mean value for the AMH decreases with increasing age and was statistically significant at the different age group levels (P &minus;2.250 - 4.136;0.953 - 2.350;0.240 - 0.792 and 0.054 - 0.216 respectively for the age groups. This study summarizes the findings concerning AMH and its role as a marker for the quantitative aspect of ovarian reserve, ovarian aging, as well as ovarian dysfunction in this region of the country.

Relationship of Anti-Mullerian Hormone to Reproductive Traits in Katahdin Ewes Bred in Late Spring or Fall

Anti-Mullerian hormone (AMH) is an endocrine marker for fertility in many species. This study investigated possible correlations between serum AMH concentrations, mean number of lambs born (out-of-season in spring or fall), and estimated breeding values (EBVs) for number of lambs born (NLB), number of lambs weaned (NLW), maternal weaning weight (MWWT), weaning weight (WWT), and maternal index (determined by Sheep Genetics Australia). Blood was collected at breeding from Katahdin ewes between 0.7 and 7 years of age in 2015 (n = 163) for the analysis of serum concentrations of AMH. Anti-Mullerian hormone concentration was either expressed quantitatively or divided into quartiles (AMH Q1 through Q4, with Q1 the lowest and Q4 the highest, pg/ml). Data were analyzed by PROC CORR, GLM or chi-squared using SAS. Mean serum AMH was 182 ± 11 pg/ml and ranged from 0 to 1112 pg/ml. There was no correlation between serum AMH and EBVs for NLB, NLW, MWWT, WWT and the maternal index. Serum AMH concentration was similar in ewes in different age categories (P = 0.157). There was a correlation between EBV for NLB (0.29;P = 0.0002) and NLW (0.19;P = 0.013) with average number of lambs born. Ewes in the lowest AMH quartile (Q1) had a lower mean number of offspring born from spring breeding compared with ewes in other AMH quartiles (Q2, Q3, and Q4;P < 0.05). Further study is needed to determine the effectiveness of using serum AMH for selecting ewes for out-of-season (spring) breeding.

Clinical efficacy of anti-Mullerian hormone inspection in supporting diagnosis for climacteric disorders

The diagnosis of climacteric disorders in gynecology is performed on the basis of symptoms rather than hormonal levels. Generally, the follicle-stimulating hormone (FSH) level increases when the 17β-estradiol (E2) level decreases in menopause. However, the problem of these hormones should be determined by strict timing of sampling, and there are individual specificities of decreases of hormone levels. We considered that anti-Mullerian hormone (AMH) can be measured at any time of the menstrual cycle and that it shows ovary functional decline earlier than FSH/E2, and we examined whether AMH would possibly become a good index for climacteric disorders. The subjects were 163 healthy females and 21 patients with climacteric disorders between 20 and 59 years old. We examined AMH, FSH and E2 at the same time. It is understood that in healthy females, AMH decreases with age and a decline in ovary function occurs at a relatively early age. Patients visiting clinics for climacteric disorders often have normal-range serum FSH/E2 levels, and it is clear that these values could not serve as indices of menopause at these inspections. Upon measurement of AMH in patients with climacteric disorders, most showed less than normal range (< 14 pmol/L), suggesting a decline in ovarian function. In addition, AMH was low in females with climacteric disorders compared with those without them. In conclusion, AMH was suggested as an objective index for climacteric disorders and possibly as a new diagnostic marker.

Serum leptin level in Sudanese women with unexplained infertility and its relationship with some reproductive hormones

BACKGROUND The excessive concentration of leptin has negative effects on all aspects of female reproduction.Despite this established relationship,the exact role of leptin in women’s fertility is not clear enough and needs more clarification.AIM To evaluate the serum leptin levels in Sudanese women and to ascertain the relationship between serum leptin levels and unexplained infertility(UI).METHODS A matched(age and body mass index)case-control study was conducted from March 2021 to February 2022.The study samples were 210 women with UI and 190 fertile women of reproductive age who were attending the maternity hospitals and fertility clinics in Khartoum state Sudan.The serum concentration of leptin and other serum biomarkers were determined using enzyme-linked immunosorbent assays.RESULTS The results showed that there was a highly statistically significant difference between the two groups(P<0.001)for all examined eight biomarkers.Whereby,leptin,luteinizing hormone(LH)/follicular stimulating hormone(FSH)ratio,prolactin hormone(PRL)and testosterone(T)were significantly higher in the UI group compared with the control group.In contrast,FSH and estradiol(E2)/T ratio were significantly lower in the UI group than in the control group and the effect size test for the difference between the two groups was very large(effect size>0.80),for leptin level,LH/FSH ratio,PRL level,and E2/T ratio,and large(effect size 0.50-≤0.80)for FSH and T.CONCLUSION This study reveals that leptin could be a potential biomarker for UI in Sudanese women and it may be useful for identifying women with a high risk of infertility.

Effect of modified laparoscopic salpingectomy on ovarian reserve:Changes in the serum antimüllerian hormone levels

Objective:To retrospectively estimate the impact of modified laparoscopic salpingectomy on the ovarian reserve in infertile women.Methods:There were 74 infertile women undergone modified laparoscopic salpingectomy from June 2016 to January 2017,and their levels of serum antimüllerian hormone,basal follicle-stimulating hormone and estradiol were reviewed retrospectively.Results:No significant change was detected in serum antimüllerian hormone at 3 months after surgery compared to preoperative level(p=0.857).Similar changes were observed for the basal follicle-stimulating hormone(p=0.102)and estradiol(p=0.233)level.Conclusions:Our results revealed that modified laparoscopic salpingectomy might be a valuable treatment for hydrosalpinx before in vitro fertilization.

Effect of thyroid hormone on serum NO concentration and iNOS activity of intestinal mucosa in septic rats

Objective To investigate the effect of exogenous thyroid hormone on serum NO and iNOS activity of intestinal mucosa in septic rats. Methods Septic model was established by cecal ligation puncture (CLP) in male SD rats. Triiodothyronine ( T3 ) was administered intraperitoneally to correct the low T3 syndrome of septic rats. Blood was collected to examine serum NO and thyroid hormone concentration. Intestinal mucosa iNOS activity was assayed using immunochemical stain. Results Mortality rate in the prevention group was significantly lower than the septic group (Log rank = 3. 85, P 【 0.05). Serum NO concentration was significantly lower in the prevention group (F=19.6,F【0.01). The degree of inflammatory injury of intestinal mucosa was much milder in the prevention group than in the septic group (x2 = 5.303,P【0. 05). Mucosa iNOS activity was also significantly lower in the prevention group (x2 = 4. 876, P【0. 01). Conclusion Thyroid hormone protects the intestinal mucosa barrier inhibiting the expression of

Investigating structural impact of a valine to isoleucine substitution on anti-Müllerian hormone in silico and genetic association of the variant and AMH expression with egg production in chickens

Anti-Mullerian hormone(AMH)acts in maintaining orderly cyclic recruitment of early follicles,suggesting that it is a promising can didate for in flue ncing an imal reproductive efficiency.This study aimed to elucidate the effect of a missense mutati on of Val566lle on the structure of AMH protein and the genetic association of Val566lle and AMH expression with egg production in chickens.Structural perturbations of Val566lle were predicted by homology modeling.The association of the variant with the number of eggs was tested using a quantitative trait transmission disequilibrium test model.AMH expression in granulosa cells in Lueyang black-boned chickens was compared with that in Nick chickens.The Vai566 of AMH is a non?conservative amino acid among mammals and birds,but its hydrophobicity is completely conservative.The substitution of Vai566 for lie566 pote ntially disrupted hydroge n bonds and solve nt accessibility of 22 residues and created a short a-helix in the C terminus of AMH.Despite having striking structure-disrupting potential,the variant was not statistically associated with the number of eggs(P>0.05)in the Lueyang black-boned chickens.We did not detect differential expression of AMH betwee n Lueya ng black-b oned chicke ns and Nick chickens(P>0.05).These results con firmed the structural impact of Val566lle,but suggested that Val566lle and AMH expression might not be the major genetic determinants for egg production in Lueyang black-boned chickens.
