Predicting Semen Analysis Parameters from Testicular Ultrasonography Images Using Deep Learning Algorithms: An Innovative Approach to Male Infertility Diagnosis

Objectives: Semen analysis is universally regarded as the gold standard for diagnosing male infertility, while ultrasonography plays a vital role as a complementary diagnostic tool. This study aims to assess the effectiveness of artificial intelligence (AI)-driven deep learning algorithms in predicting semen analysis parameters based on testicular ultrasonography images. Materials and Methods: This study included male patients aged 18–54 who sought evaluation for infertility at the Urology Outpatient Clinic of our hospital between February 2022 and April 2023. All patients underwent comprehensive assessments, including blood hormone profiling, semen analysis, and scrotal ultrasonography, with each procedure being performed by the same operator. Longitudinal-axis images of both testes were obtained and subsequently segmented. Based on the semen analysis results, the patients were categorized into groups according to sperm concentration, progressive motility, and morphology. Following the initial classification, each semen parameter was further subdivided into “low” and “normal” categories. The testicular images from both the right and left sides of all patients were organized into corresponding folders based on their associated laboratory parameters. Three distinct datasets were created from the segmented images, which were then augmented. The datasets were randomly partitioned into an 80% training set and a 20% test set. Finally, the images were classified using the VGG-16 deep learning architecture. Results: The area under the curve (AUC) values for the classification of sperm concentration (oligospermia versus normal), progressive motility (asthenozoospermia versus normal), and morphology (teratozoospermia versus normal) were 0.76, 0.89, and 0.86, respectively. Conclusions: In our study, we successfully predicted semen analysis parameters using data derived from testicular ultrasonography images through deep learning algorithms, representing an innovative application of artificial intelligence. Given the limited published research in this area, our study makes a significant contribution to the field and provides a foundation for future validation studies.

Intracellular Retention of Estradiol is Mediated by GRAM Domain-Containing Protein ASTER-B in Breast Cancer Cells.

Elevated blood levels of estrogens are associated with poor prognosis in estrogen receptor-positive (ER+) breast cancers, but the relationship between circulating blood hormone levels and intracellular hormone concentrations are not well characterized. We observed that MCF-7 cells treated acutely with 17β-estradiol (E2) retain a substantial amount of the hormone even upon removal of the hormone from the culture medium. Moreover, global patterns of E2-dependent gene expression are sustained for hours after acute E2 treatment and hormone removal. While circulating E2 is sequestered by sex hormone binding globulin (SHBG), the potential mechanisms of intracellular E2 retention are poorly understood. We found that a mislocalization of a steroid-binding GRAM-domain containing protein, ASTER-B, to the nucleus, which is observed in a subset of breast cancer patients, is associated with higher cellular E2 retention. Accumulation and retention of E2 are related to the steroidal properties of E2, and require nuclear localization and steroid binding by ASTER-B, as shown using a panel of mutant ASTER-B proteins. Finally, we observed that nuclear ASTER-B-mediated E2 retention is required for sustained hormone-induced ERalpha chromatin occupancy at enhancers and gene expression, as well as subsequent cell growth responses. Our results add intracellular hormone retention as a mechanism controlling E2-dependent gene expression and downstream biological outcomes. Implications: Mislocalized nuclear ASTER-B, which binds estradiol to support the functions of ER, can provide an alternate means of enhancing the biological effects of E2 in breast cancers and may be a potential therapeutic target that addresses multiple aspects of estrogen bioavailability.

Association Between Chlamydia trachomatis and Helicobacter pylori with Inflammation in Polycystic Ovary Syndrome: A Cross-Sectional Study.

Objective: Chronic low-grade inflammation occurs in polycystic ovary syndrome (PCOS), and there are many contributing factors. In this study, we aimed to investigate Helicobacter pylori and Chlamydia trachomatis infections in patients with PCOS and to evaluate the association between these microorganisms and the inflammatory process in the etiology of the disease. Materials and Methods: This comparative cross-sectional clinical study was conducted at Balıkesir University Hospital and included 40 female patients diagnosed with PCOS in the gynecology outpatients clinic and 40 healthy female controls. Demographic data were recorded. Blood hormone profiles and biochemical parameters were analyzed. An enzyme-linked immunosorbent assay test kit was used to measure H. pylori IgG and C. trachomatis IgG. Results: According to the analysis of the study data, there was no significant association between the PCOS and non-PCOS groups with regard to the presence of Helicobacter pylori IgG (p = 0.1) and Chlamydia trachomatis IgG (p = 0.338). CRP levels were significantly higher in the PCOS group (p = 0.001). In the subgroup analyses, the CRP levels were not significantly different between the H. pylori and C. trachomatis antibody-positive and -negative groups. Diabetes mellitus was significantly associated with PCOS (p = 0.005). The smoking rate was significantly higher in the control group than in the PCOS group (p = 0.036). Compared to the control group, the BMI, LH, HOMA-IR, TSH, and TG levels were significantly higher in participants with PCOS (p = 0.000; p = 0.004; p = 0.001; p = 0.001; p = 0.043; p = 0.000). FSH was lower in PCOS patients compared to controls (p = 001). In the subgroup analyses, no significant differences were found between the H. pylori and C. trachomatis antibody-positive and -negative groups. Conclusions: PCOS is characterized by chronic nonspecific low-grade inflammation. The etiopathogenesis of PCOS involves comorbidities that cause a chronic inflammatory process. However, the possible infective causes still seem to be open to investigation. In particular, studies on microbiota and periodontal diseases in PCOS may provide important contributions.

Seasonal Influence on the Impact of Human Chorionic Gonadotropin (hCG) on Testicular Haemodynamics and Hormonal Responses in Canines: A Comparative Study.

Human chorionic gonadotropin (hCG) is widely used to treat reproductive dysfunction by enhancing testicular blood flow and stimulating hormonal activity. This study investigates the seasonal variations in the response to hCG treatment in male dogs, focusing on its effects on testicular blood flow and plasma concentrations of testosterone and oestrogen. Conducted across different seasons (spring, summer, fall and winter), the study utilised colour Doppler ultrasonography to measure testicular haemodynamics and analysed hormonal levels at multiple time points post-hCG injection. The findings revealed that the response to hCG is modulated by seasonal factors, with significant variations in both blood flow and hormone levels. A significant negative relationship was indicated between testicular blood flow and testosterone levels, particularly during spring and summer. These results suggest that seasonality should be considered when administering hCG for reproductive treatments in canines.

Lysosomal Acid Lipase Deficiency Investigation In Patients Diagnosed With Primary Hyperlipidemia

Objective: Cholesteryl ester storage disease (CESD) is a disease where a considerable decrease in the activity of lysosomal acid lipase (LAL) enzyme resulting from the mutation in lipa (lysosomal acid lipase) gene is observed, which goes along with dyslipidemia and involves a wide clinical condition ranging from hepatosteatosiz to liver fibrozis; and whose diagnosis is usually skipped. LAL deficiency should be taken into consideraiton for patients who are suffering from hepatosplenomegaly and/or high transaminase level, high ldl and/or low hdl without having problems of obesity or metabolic syndrome. Methods: Our study included 75 patients who applied to Gaziantep University Faculty of Medicine Pediatric Endocrinology and Metabolic Diseases Clinic, 35 patients were excluded out of study because of having secondary hyperlipidemia, 15 patients were diagnosed with non-familial hyperlipidemia, and 25 patients were diagnosed with familial hyperlipidemia. Patients were divided into three groups according to phenotypes; type 2, type 3 and type 5, at the same time patients were divided into three groups according to the treatment as applying lipid aferesis, lipid lowering treatment and dieting, and only dieting group. Gender, age, height, weight, height standard deviation score, weight standard deviation score, follow-up period, complaints, relative body weight were recorded. Lipid profiles, transaminase levels, complete blood count, hormone profiles, bone densitometry (DEXA), echocardiography and LAL enzyme profiles of patients were evaluated. Blood samples were taken to filter paper from totally 40 patients; 15 patients with non-familial hyperlipidemia to eveluate LAL activity and also the same samples were taken from 15 patients with primary hyperlipidemia and 25 patients with familial hyperlipidemia to eveluate LAL levels. Results: We determined the LAL enzyme levels at the normal reference ranges in all of 40 patients with primary hyperlipidemia. Conclussion: In our study there was no relationship between familial hyperlipidemia and lal levels but we think results must be eveluated with the larger number of patients.

Immunocastration caused dysfunction of Père David’s deer (Elaphurus davidianus)

Abstract The population density of Père David’s deer (Elaphurus davidianus) in Jiangsu Dafeng Milu Nature Reserve was excessively high due to an overemphasis on population recovery, while ignoring the crucial relationship between population size and habitats. This study used immunocastration to capture four Père David’s deer and observed their behavior. Their blood was collected for sex hormone testing, transcriptomics, and metabolomics analysis. In addition, six uncastrated Père David’s deer were included as control group. The results showed that reproductive behavior was absent in castrated Père David’s deer, while castrated individuals exhibited a significant decrease in blood hormone testosterone concentration compared to uncastrated Père David’s deer. Transcriptome and metabolome analyses revealed 450 differentially expressed genes (DEGs) and five differentially expressed metabolites (DEMs), Combined analysis of transcriptome and metabolic data revealed a significant correlation between DEGs and DEMs. It shows that using immune castration to control the population of Père David’s deer may disrupt their cell apoptosis and disturb the cell cycle, leading to abnormal pathways and promoting the onset of many diseases. Therefore, a cautious approach should be adopted toward immune castration as a means of population control. This study can provide valuable references for the standardized management of Père David’s deer populations.

FREEMARTINISMO EM BOVINOS

Freemartinism syndrome affects the reproductive system of heifers and other female ruminants as a result of the twin gestation of heterozygous individuals, which a process of early vascular anastomosis allows the exchange of blood cells and hormones in a common circulation between the two fetuses before their sexual differentiation. The purpose of this paper is to review the literature on cases of intersexuality in cattle over the years, bringing together the studies and specifying the possible causes, formation, differentiation of the affected animals and the diagnostic methods available.

Effect of a Bacillus subtilis-based direct-fed microbial, on milk yield, milk components, feed intake and plasma hormones and metabolites in lactating Holstein cows

To investigate the effects of a Bacillus-based direct-fed microbial on milk production and related factors, a study was conducted on Holstein cows (n = 28) starting at 90 ± 11 DIM. The cows were divided into two dietary groups: a control group (CON) that received a total mixed ration (TMR), and a Bacillus-fed group (DFM) that received the same TMR along with a Bacillus subtilis product containing two strains (747 and 1781) in equal amounts. The study lasted for 25 wk and included both primiparous and multiparous cows. The cows were housed in a free-stall barn and were provided with ad libitum TMR, which was fed twice a day. Their daily meals and dry matter intake (DMI) were recorded during wk 1–4 and wk 19–25 using electronic feeders. Milk samples were collected weekly during morning and evening milkings and analyzed for milk fat, protein, lactose, and milk urea nitrogen (MUN). Blood samples were also collected weekly and analyzed for plasma glucose, insulin, cholesterol, insulin-like growth factor 1 (IGF1), and progesterone concentrations. Additionally, rumen fluid samples were collected and evaluated for various species of bacteria. One of the key findings was that daily 4 % fat-corrected milk production (FCM) was influenced by the interaction between treatment (DFM vs. CON) and parity (primiparous vs. multiparous), with multiparous DFM cows producing 11 % more FCM compared to CON. The DFM cows also had a higher milk fat percentage (4.41 % vs. 4.02 %) and MUN concentrations were 1.0 mg/dL higher in the DFM group. In terms of blood metabolites and hormones, multiparous DFM cows had lower plasma cholesterol, glucose, and insulin concentrations compared to CON multiparous cows. However, there were no significant differences between the groups in terms of plasma IGF1 concentrations, insulin-to-glucose ratios, and luteal phase plasma progesterone concentrations. The analysis of rumen fluid samples revealed that the abundance of Ruminococcus albus and Fibrobacter succinogenes group I was greater in the DFM cows compared to CON cows. Furthermore, during the periods when feed intake was measured, the DFM cows had a 9 % reduction in feed intake and a 14 % improvement in feed efficiency (FCM per DMI) compared to CON cows. In conclusion, the two-strain Bacillus product used in this study (Certillus) showed potential as an effective direct-fed microbial. It was found to increase feed efficiency and milk production by altering the composition of ruminal microbiota and metabolism in the cows.

Echocardiographic and Impedance Cardiography Analysis of Left Ventricular Diastolic Function in Acromegaly Patients.

BACKGROUND Due to the chronic effects of excess growth hormone (GH) and insulin-like growth factor-1 (IGF-1), patients with acromegaly (AC) may develop acromegalic cardiomyopathy with biventricular hypertrophy, systolic and diastolic dysfunction, resulting in congestive heart failure. This study aimed to evaluate the echocardiographic parameters of left ventricular (LV) diastolic function and impedance cardiography (ICG) parameters of cardiovascular hemodynamics in patients with AC. MATERIAL AND METHODS A total of 33 patients (male to female ratio: 1.2; mean age 47 years) newly diagnosed with AC based on the blood hormone levels and imaging study findings were included into this observational cohort study. The echocardiographic parameters of LV diastolic function included early diastolic velocity of the average mitral annulus (e'avg), ratio of early diastolic mitral inflow velocity to early diastolic mitral annular tissue velocity (E/e'ratio), mitral flow early (E) and late (A) phase ratio (E/A). The ICG parameters included stroke volume index (SI), cardiac index (CI), acceleration index (ACI), systemic vascular resistance index (SVRI), total arterial compliance index (TACI) and thoracic fluid content (TFC). RESULTS Poorer parameters of LV diastolic function corresponded to the parameters assessed via ICG: 1) lower ratio E/A was associated with lower SI (P<0.001), CI (P=0.007), VI (P=0.04), ACI (P=0.02), TACI (P=0.005) and higher SVRI (P<0.001), 2) lower E/e' ratio was associated with higher TFC (P=0.03); 3) lower e'avg was associated with lower SI (P=0.01) and CI (P=0.048) and higher SVRI (P=0.03), despite normal LV ejection fraction. CONCLUSIONS Impaired LV diastolic function in AC is associated with impaired pumping function of the heart and higher afterload as assessed on ICG.

8144 Hypertension in Sheehan Syndrome: A Diagnostic Challenge

Abstract Disclosure: E. Ahsan: None. F.F. Foo: None. C. Lesniak: None. M. Akula: None. K. Hu: None. R. Ong: None. K. Chalasani: None. J. Cheng: None. S. Holland: None. Introduction: Postpartum pituitary necrosis, commonly known as Sheehan syndrome (SS), is the term used to describe the necrosis of anterior pituitary gland cells that occurs after significant postpartum bleeding, hypovolemia, and shock. This typically occurs after delivery, during which the mother suffers significant blood loss. The pituitary gland fails to produce hormones due to this blood loss. Depending on the degree of tissue damage, SS can have an acute or chronic course, and patients may present with a wide range of clinical symptoms at diagnosis. Acute SS is associated with postpartum pituitary infarction, which can result in hypotension, shock, hypoglycemia, hyponatremia, headache, vision disturbances, unconsciousness, and an inability to lactate. We present a rare case of SS where the patient experienced hypertension instead of classic hypotension due to postpartum preeclampsia. Clinical Case: A 40-year-old female with no significant medical history presented to the hospital for scheduled induction of labor for polyhydramnios and underwent vacuum-assisted vaginal delivery and postpartum hysterectomy due to severe postpartum hemorrhage secondary to DIC. The postpartum course was also complicated by preeclampsia with severe features. Patients developed features like excessive fatigue, hypoglycemia, hyponatremia, hypothyroidism, polyuria, and failure of lactation, which were consistent with panhypopituitarism secondary to Sheehan syndrome. However, the patient was hypertensive to 145/91 before steroids were given. Labs were significant for serum sodium 116 mmol/L (135-145 mmol/L), FSH &amp;lt;0.7 mIU/mL (Follicular Phase: 2.5-10.2, Mid-cycle Peak: 3.1-17.7, Luteal Phase: 1.5-9.1, Postmenopausal: 23.0-116.3), LH &amp;lt;0.2 mIU/m (Follicular Phase: 1.9-12.5, Mid-Cycle Peak: 8.7-76.3, Luteal Phase: 0.5-16.9, Postmenopausal: 10.0-54.7), Prolactin: 2.4 ng/mL (Non-pregnant: 3.0-30.0, Pregnant: 10.0-209.0, Postmenopausal: 2.0-20.0), PM Cortisol on admission: 1.10 ug/dL (3.44-16.76 ug/dL), plasma ACTH 7 pg/mL( 6 - 50 pg/mL), TSH 0.430 uIU/mL (0.550 - 4.780 uIU/mL), FT4 0.59 ng/dL - 1.76 ng/dL). MRI of the brain pituitary showed- A 1.5 cm region of hypoenhancement and an additional 2 mm focus of hypoenhancement in the sella, findings represent evolving pituitary necrosis. The patient received 24 units of blood transfusion and hormone replacement therapy, followed by outpatient endocrinology follow-up. Clinical lessons: Although considerable blood loss causes hypotension in patients with SS, additional postpartum medical issues can sometimes result in atypical presentations. In our patient, postpartum preeclampsia caused hypertension. Identifying the atypical symptoms of SS is just as vital as identifying its typical features to prevent potentially fatal consequences.

ROLE OF VIRUDDHAHARA IN CAUSING INFERTILITY- A CONCEPTUAL STUDY

In the present era, many lifestyle disorders are caused by unhealthy food habits and practices; infertility is one of them. The incidence has increased due to diversified daily routines, faulty food habits, and westernization, which affect the endocrine system and physiological factors. These issues can cause irregular menstruation, ovulation disorders, PCOS, fallopian tube blockage, endometriosis, hormonal disorders, and uterine abnormalities, ultimately leading to infertility. The Ayurvedic explanation of ‘Viruddhahara’ is a unique concept. Acharya Charaka mentioned Shandhya and Santanadosha while listing the diseases caused by Viruddhahara1 . Viruddhahara impairs Rasadhatu, which leads to the Dushti of its upadhatu, Artava(Menstrual blood). Long-term practice of Viruddhahara (unhealthy food habits) causes Artavadushti and also affects the ovum, menstrual blood, and ovarian hormones. Viruddhahara significantly affects the Garbhasambhava samagri. The practice of Satmya Ahara and Vihara can help avoid multiple causative factors of infertility, such as Beeja dosha, Artava or Shukradushti, and yonivyapat. Infertility is also caused by obesity and other diseases resulting from faulty food habits.

Effect of Khat Chewing on the Level of Testosterone Hormone in Blood among Adult Males in Rada'a Town -Yemen

This study relied on case-control method, and included 50 healthy people who were randomly selected out of people chewing khat with age ranged between 18-30 years old and had a body mass index (BMI ) of less than 30. All people with any diseases, factors and treatments that interfere or affect the results of this study have been excluded. The sample was divided into two groups, i.e. experimental and control. The experimental group was further divided into two groups. The first consisted of 20 chewing khat daily , while the second consisted of 10 chewing khat only once a week. The control group included 20 people who do not chew khat. Venous blood was collected from every group and subjected directly to measure of testosterone hormone level in Al-Saeeda Specialized Laboratories in Rada'a city. Also, this study showed that the mean level of testosterone in people who chew khat daily was significantly higher ( p = 0 026 ) in comparison with those who do not chew it (control group), the average increase in the level of testosterone hormone in daily khat chewer group by 1ng/ml of serum, Also the results showed no significant difference observed in testosterone level between one time per week khat chewers and non-chewing but the level of testosterone increased gradually from zeero day (non-chewing) and reached the maximum with seven days per week chewing group. The study also showed that there was no statistically significant effect of the variables of age, body mass, time period of chewing khat and the number of hours of chewing khat per day on the level of testosterone in the blood. We conclude that the effect of khat on testosterone was very low when compared to other studies, may be because khat contains some chemicals such as pesticides and agricultural fertilizers that directly or indirectly affect the level of testosterone in the blood of khat chewer.

Determination of Fertility Hormones and Adipokines by LC-MRM/MS Analysis.

Due to the increase in the rate of male and female infertility, assisted fertilization practices are currently adopted as valid support for couples unable to get pregnant. Analytical approaches for fertility hormone dosages are constantly being developed, following the technological progress of fertilization methods that have evolved for more than a century. Indeed, the analysis of fertility hormones in serum samples is a common clinical practice to check the fertility state, but absolute quantification of these hormones is a great challenge due to biological variability and low serum concentrations. Currently, ELISA (enzyme-linked immunosorbent assay) based methods are the most used analytical techniques to quantify hormones in blood in clinical settings. The current Article discusses the development of a liquid chromatography-tandem mass spectrometry method (LC-MS/MS) to monitor multiple fertility hormones of a protein nature in a single chromatographic run, i.e., LH (luteinizing hormone), FSH (follicle-stimulating hormone), TSH (thyroid-stimulating hormone), AMH (anti-Müllerian hormone), adiponectin, ghrelin, leptin, glucagon, and obestatin. Particular attention has been paid to the AMH hormone, whose ELISA-based quantification is known to be controversial due to the poor reproducibility between the various kits used. For AMH, the internal standard method was used for the quantitative determination to compare mass spectrometry data to the ELISA assays performed by an accredited analysis laboratory on a cohort of samples from women aged between 18 and 60 years. The ability to monitor multiple transitions by LC-MRM/MS ensured both high specificity and high selectivity, which is necessary for the quantification of protein and steroid hormones, besides improvements in data reproducibility and reduced analysis times and costs.

Herbal Cellular Concentrate for Type 2 Diabetes

Diabetes is a group of metabolic disorders associated with chronic hyperglycemia in the blood due to defects in insulin secretion, insulin function, or both. Although the proper treatment of diabetes includes insulin injection continuously to maintain blood glucose levels, nowadays, there is an increasing interest in the use of alternative approaches for treating insulin resistance, and T2D Chicory significantly reduces blood sugar and glucose fluctuations, increases metabolism due to inulin in type 2 diabetes patients with excess weight. Equisetum arvense is one of the most effective plants for blood sugar, stabilizing metabolism, and hormone production. Tuberous roots are rich in inulin, enabling glucose utilization in the human body, and can potentially ameliorate insulin sensitivity in diabetic patients. Blueberry leaves improve insulin sensitivity and action. Galega officinalis lowers blood sugar levels for prediabetes and type-2 diabetes patients. Due to the side effects and temporary use of chemical drugs, herbal and natural medicines and chemical drugs are recommended for people with diabetes. However, more scientific studies are needed to confirm the effectiveness of herbal supplements in diabetes cases.

Transcriptomic and metabolomic data of goat ovarian and uterine tissues during sexual maturation

The ovaries and uterus are crucial reproductive organs in mammals, and their coordinated development ensures the normal development of sexual maturity and reproductive capacity. This study aimed to comprehensively capture the different physiological stages of the goat’s sexual maturation by selecting four specific time points. We collected samples of ovarian and uterine tissues from five female Jining Gray goats at each time point: after birth (D1), 2-month-old (M2), 4-month-old (M4), and 6-month-old (M6). By combining transcriptomic sequencing of 40 samples (including rRNA-depleted RNA-seq libraries with 3607.8 million reads and miRNA-seq libraries with 444.0 million reads) and metabolomics analysis, we investigated the transcriptomic mechanisms involved in reproductive regulation in the ovary and uterus during sexual maturation, as well as the changes in metabolites and their functional potential. Additionally, we analyzed blood hormone indices and uterine tissue sections to examine temporal changes. These datasets will provide a valuable reference for the reproductive regulation of the ovary and uterus, as well as the regulation of metabolites during sexual maturation in goats.

Blood Sampling and Hormone Measurement for Determining the Stage in the Ovarian Cycle in Marmosets.

Common marmosets are small New World monkeys. Since many of their biological mechanisms are similar to those of humans, marmosets are potentially useful for medical and human biology research across a range of fields, such as neuroscience, regenerative medicine, and development. However, there is a lack of literature describing methods for many basic experiments and procedures. Here, detailed methods for determining the levels of sex hormones (progesterone, estradiol, and chorionic gonadotropin) in marmosets are described. The measurement of these hormones enables the prediction of the stage in the ovarian cycle, which is typically 26-30 days in marmosets; accurate determination is essential for the harvesting of oocytes/zygotes at the correct time point and for the preparation of host females for the generation of genetically modified marmosets. Additionally, the measurement of sex hormone levels is useful for endocrinology, ethology, early development, and reproductive biology studies. This protocol provides a detailed description of the methods for blood sampling from the femoral vein, separation of plasma for hormone measurement, measuring chorionic gonadotropin levels using urine and plasma, resetting the ovarian cycle using injections of a prostaglandin F2α analog to shorten and synchronize the cycle, and promoting follicular growth and ovulation by injecting follicle-stimulating hormone and chorionic gonadotropin. Using these protocols, the stages in the ovarian cycle can be determined for the timely collection of oocytes/zygotes.

Features of intestinal microbiota taxonomic composition and their relation with hormonal and immune status assessed in women with external genital endometriosis

Aim: systemically assessed characteristics of intestinal microbiota taxonomic composition in relation to parameters of hormonal and immune status in patients with external genital endometriosis (EGE).Materials and Methods. The controlled cross-sectional study included 33 patients with ЕGE comprising main group, and 30 healthy women enrolled to control group. All women underwent assessment of hormonal status and cytokine expression levels in peripheral blood. Level of blood hormones estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL) was carried out using enzyme-linked immunosorbent and chemiluminescent assays. Expression levels of cytokines such as interleukin (IL) IL-6, IL-8, tumor necrosis factor alpha (TNF-α) were analyzed by an enzyme-linked immunosorbent assay. Taxonomic composition of intestinal microbiota at the level of phyla and genera was carried out by 16S ribosomal RNA genesequencing. Microbial community α-diversity, the Chao1, ACE, and Sobs indices were used.Results. The concentration of blood E2 in main group was significantly higher compared to control group. Also, women with ЕGE had higher plasma concentrations for IL-6, IL-8, IL-17 and TNF-α compared to those in control group (p &lt; 0.001). While analyzing bacterial community α-diversity in main group, Chao1 index was found to be significantly decreased. At the phylum level, the Firmicutes/Bacteroidetes ratio was increased in patients with ЕGE compared with that in control group. Among the 20 largest genera in patients with ЕGE, significant abundance was observed for Lachnospira, Blautia, Dorea, Streptococcus, Eubacterium hallii_group paralleled with significant decline in Bifidobacterium and Eubacterium eligens_group. A positive correlation was obtained between estrogen levels and the number of representatives from the genera Eubacterium hallii_group and Streptococcus, IL-8 and Streptococcus, TNF-α and Streptococcus and Lachnospira, as well as a negative correlation between TNF-α and Bifidobacterium.Conclusion. A relation between dysbiotic intestinal alterations and developing endometriosis was found. The identified correlations between altered taxonomic composition of the intestinal microflora and parameters of hormonal and immune status in patients with ЕGE suggest that intestinal microbiota is involved in pathophysiology of endometriosis.

Prognostic factors for the development of obstetric and perinatal pathology in pregnant women under conditions of iodine deficiency

According to the World Health Organization (WHO), iodine deficiency is the main cause of mental retardation in children, and at the same time, it significantly affects the pathological course of pregnancy and childbirth. The problem is complicated by the fact that more than 100.000 children with cretinism are born annually in the world. In recent years, there has been a significant increase in endemic thyroid diseases in Ukraine, the main cause of which is insufficient iodine consumption. Iodine deficiency conditions are aggravated by socio‑economic, ecological and radiological factors, while at the same time mass and group iodine prophylaxis is carried out improperly on the state level. Objective. To determine prognostic factors for the development of obstetric and perinatal pathology in pregnant women under conditions of iodine deficiency. Materials and methods. To compile a diagnostic table of prognostic factors of the threat of miscarriage, the analysis has been performed of 185 cases of threatened abortion (111 in the first trimester, 56 in the second, 18 in the third) and 223 control observations (without the threat of miscarriage). A diagnosis was considered as confirmed if it was established using all applicable methods of examination of pregnant women. Results. The risk factors of the occurrence of perinatal pathology include hypothyroxinemia (DC=–2.5) and ioduria in pregnant women less than 100 mg/l (DC=–1.9). In the intranatal period, a negative impact is exerted by the lack of coordination and weakness of labor activity (DC=–8.1). Levels of thyroid‑stimulating hormone (TSH) in umbilical cord blood &gt;10 mIU/ml (DC=–4.6) are the prognostically favorable factors for the postnatal adaptation of the newborn, especially TSH levels &gt;20 mIU/ml (DC=–8.3). Conduction of iodine prophylaxis (DC=7.7) and ioduria in pregnant women 200—400 mg/l (DC=5.1) contribute to the improvement of perinatal outcomes. Conclusions. A retrospective review of the prognostic significance of the diagnostic table in 188 patients with diffuse nontoxic goiter revealed its sensitivity (76%) and specificity (68%). On the basis of the conducted research, we established risk factors for the development of obstetric and perinatal complications, and assessed their informativeness. The developed algorithm is represented by a diagnostic table for the prediction of complications of pregnancy, childbirth and adverse perinatal outcomes in women with endemic thyropathies.

EFFECTS OF LIVE BODY WEIGHT AND LEPTIN CONCENTRATION ON IRAQI CHICKENS FERTILITY AND HATCHABILITY

This Study was conducted out at the Ministry of Agriculture's Poultry Research Station/Animal Resources Department/Agricultural Research Center. To see how body weight (BW) and leptin hormone (LEP) levels in breeder blood affect fertility and hatchability. 140 Iraqi local laying chickens (120 females + 20 males) aged 28 weeks were used in the study. Following the numbering of females, the birds were grown in individual cages and dispersed sequentially on cages. The experiment was divided into three periods, each lasting 28 days, during which the breeder's live body weight was recorded and divided into two categories (greater than 1.5 kg and less than 1.5 kg), and blood samples were collected at the end of each period to determine the concentration of leptin hormone in the breeders' blood. For comparison between mothers' performance, hormone concentration is separated into three groups: high, medium, and low. The percentage of fertile eggs (FE), the percentage of hatched chicks from total eggs (HAT), the percentage of hatched chicks from fertile eggs (HAF), and the percentage of mortality (MO) all showed a significant increase (p&lt;0.05), and a linear relationship was discovered between the studied traits and hormone concentration levels. Leptin arrived at the best predictive values that reflect reality by computing regression and correlation coefficients and using a hypothetical technique in estimating prediction results. This study concludes that body weight and leptin levels have unknown impacts on hatching fertility rates.

Development of an LC-HRMS/MS Method for Quantifying Steroids and Thyroid Hormones in Capillary Blood: A Potential Tool for Assessing Relative Energy Deficiency in Sport (RED-S).

Relative energy deficiency in sport (RED-S) is a condition that arises from persistent low energy availability (LEA), which affects the hypothalamic-pituitary axis and results in alterations of several hormones in both male and female athletes. As frequent blood hormone status determinations using venipuncture are rare in sports practice, microsampling offers promising possibilities for preventing and assessing RED-S. Therefore, this study aimed at developing a liquid chromatography-high-resolution tandem mass spectrometry (LC-HRMS/MS) method for quantifying relevant steroids and thyroid hormones in 30 μL of capillary blood obtained using Mitra® devices with volumetric absorptive microsampling technology (VAMS®). The results of the study showed that all validation criteria were met, including a storage stability of more than 28 days in a frozen state (-18 °C) and 14 days at room temperature (20 °C). The validated assay provided precise (<12%) and accurate (<13%) results for all the target analytes. Furthermore, as a proof of concept, autonomously collected VAMS® samples from 50 female and male, healthy, active adults were analyzed. The sensitivity of all analytes was adequate to quantify the decreased hormone concentrations in the RED-S state, as all authentic samples could be measured accordingly. These findings suggest that self-collected VAMS® samples offer a practical opportunity for regular hormone measurements in athletes and can be used for early RED-S assessment and progress monitoring during RED-S recovery.
