Abstract
Periovarian adipose tissue (POAT) is a type of gonadal white adipose tissue that surrounds the ovary. POAT is a source of various bioactive molecules, such as adipokines, cytokines, chemokines, growth factors and hormones. Thereby it could influence crucial ovarian functions. Recent findings showed that removal of POAT affects folliculogenesis and steroidogenesis in the ovary. Furthermore, changes in the morphology and function of POAT were observed in women during menopause or polycystic ovary syndrome. Although the relationship between the body's energy status and fertility in females is generally well known, the contribution of POAT remains still elusive. Therefore, the objective of this review is summarizing the actual state of knowledge about POAT function in physiological and pathological processes within the ovary.

Abstract
OBJECTIVES Cytomegalovirus (CMV) infection is a significant health concern affecting numerous expectant mothers across the globe. CMV is the leading cause of health problems and developmental delays among infected infants. Notably, this study examines CMV infection in pregnancy, its management, prevention mechanisms, and treatment options. METHODS Specifically, information from the Cochrane Library, PUBMED, Wiley Online, Science Direct, and Taylor Francis databases were reviewed along with additional records identified through the register, the Google Scholar search engine. Based on the search, 21 articles were identified for systematic review. RESULTS A total of six randomized controlled trials (RCTs) were utilized for a meta-analytic review. As heterogeneity was substantial, the random effects model was used for meta-analysis. Utilizing the random-effects model, the restricted maximum likelihood (REML) approach, the estimate of effect size (d = -0.479, 95% CI = -0.977 to 0.019, p = 0.060) suggests the results are not statistically significant, so it cannot be inferred that the prevention methods used were effective, despite an inverse relationship between treatment and number of infected cases. The findings indicated that several techniques are used to prevent, diagnose, and manage CMV infection during pregnancy, including proper hygiene, ultrasound examination (US), magnetic resonance imaging (MRI), amniocentesis, viremia, hyperimmunoglobulin (HIG), and valacyclovir (VACV). CONCLUSIONS The current review has significant implications for addressing CMV infection in pregnancy. Specifically, it provides valuable findings on contemporary management interventions to prevent and treat CMV infection among expectant mothers. Therefore, it allows relevant stakeholders to address these critical health concerns and understand the effectiveness of the proposed prevention and treatment options.

Abstract
Congenital heart defects (CHD) are defects detected both prenatally and after birth. They are the most common congenital defects. Despite advances in diagnosis and treatment, CHD remain an important cause of morbidity and mortality in newborns, which has a great impact on economic aspects. It is crucial to provide a holistic approach to the care of children with CHD, including regular cardiac check-ups, appropriate drug treatment, surgical or cardiac interventions as needed, rehabilitation, psychological support, and education for patients and their families. Parents experience a variety of psychological problems. This article summarizes the influence of CHD in the psychological and economic areas.

The Predictive Value of the CSA Index in the Prenatal Diagnosis of Aortic Coarctation in Ultrasound Examination Performed during the Second Trimester. J Clin Med 2023; 12:5190. [PMID: 37629232 PMCID: PMC10455770 DOI: 10.3390/jcm12165190] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 07/16/2023] [Accepted: 08/02/2023] [Indexed: 08/27/2023] Open
Abstract
BACKGROUND Aortic coarctation (CoA) is the fourth most common congenital heart defect (8-10%) which occurs at a frequency of about 20-60/100,000 births. Only 22.3% of all cases appears to be diagnosed during the second trimester of pregnancy. Since the detection of prenatal aortic coarctations is very low, every effort should be made to change this situation. According to the authors of this study, the CSAi (carotid to subclavian artery index) could serve as a reliable indicator. MATERIAL AND METHODS Ninety-six fetuses from healthy, single, pregnancies, with good ultrasound visualization between 18 and 27.5 weeks of gestation, and twenty-three fetuses suspected of aortic coarctation (postnatally confirmed) were included in this study. Our first aim was to compare the current most common method of prenatal CoA diagnosis based on the measurement of the aortic z-score in the aortic isthmus using the method suggested by us-CSAi. RESULTS Logistic regression coefficients for z-score and CSAi were analyzed as predictors of coarctation occurrence. It appears that 39.4% of coarctation occurrence can be predicted on the basis of the z-score, and 93.5% on the basis of the CSAi. The cut-off value for CSAi in the study group was 0.81 (sensitivity: 95.7%, specificity 99%). Based on the ROC curve analysis, the cut-off value for the carotid to subclavian distance (mm) was determined; the risk of coarctation increased above this value. Based on the Gini index (0.867), this value was set at 2.55 (sensitivity 82.6%, specificity 93.7%). CONCLUSIONS CSAi measurement is currently the most sensitive method for aortic coarctation detection. For the purpose of our study, this method was applied in diagnostics in the second trimester of pregnancy. This method is easy, reproducible and should be widely introduced into everyday echocardiographic diagnostics of coarctation to minimize the risk of error.

Abstract
Preeclampsia (PE) is a pregnancy-specific disorder affecting 4-10% of all expectant women. It greatly increases the risk of maternal and foetal death. Although the main symptoms generally appear after week 20 of gestation, scientific studies indicate that the mechanism underpinning PE is initiated at the beginning of gestation. It is known that the pathomechanism of preeclampsia is strongly related to inflammation and oxidative stress, which influence placentation and provoke endothelial dysfunction in the mother. However, as of yet, no "key players" regulating all these processes have been discovered. This might be why current therapeutic strategies intended for prevention or treatment are not fully effective, and the only effective method to stop the disease is the premature induction of delivery, mostly by caesarean section. Therefore, there is a need for further research into new pharmacological strategies for the treatment and prevention of preeclampsia. This review presents new preventive methods and therapies for PE not yet recommended by obstetrical and gynaecological societies. As many of these therapies are in preclinical studies or under evaluation in clinical trials, this paper reports the molecular targets of the tested agents or methods.

Abstract
BACKGROUND congenital cytomegalovirus (cCMV) infection during pregnancy is a significant risk factor for fetal and neonatal morbidity and mortality. CMV detection is based on the traditional ultrasound (US) and MRI (magnetic resonance) approach. METHODS the present review used the PRISMA protocol for identification of studies associated with CMV infection and sonographic analysis. Various search terms were created using keywords which were used to identify references from Medline, Pubmed, PsycInfo, Scopus and Web of Science. RESULTS sonographic analysis of the cCMV infection identified several of the key features associated with fetuses. The presence of abnormal patterns of periventricular echogenicity, ventriculomegaly and intraparenchymal calcifications is indicative of CMV infection in the fetus. Hyperechogenic bowels were seen frequently. These results correlate well with MRI data, especially when targeted transvaginal fetal neurosonography was carried out. CONCLUSIONS ultrasonography is a reliable indicator of fetal anomalies, due to cCMV. Fetal brain and organ changes are conclusive indications of infection, but many of the ultrasonographic signs of fetal abnormality could be due to any viral infections; thus, further research is needed to demarcate CMV infection from others, based on the ultrasonographic approach. CMV infection should always be an indication for targeted fetal neurosonography, optimally by the transvaginal approach.

Abstract
INTRODUCTION Cervical insufficiency accounts for 15% of recurrent pregnancy losses between 16 and 28 weeks of gestation. The aim of the study is to verify the effectiveness of emergency double-level cerclage with vaginal progesterone in cervical insufficiency treatment in terms of the prevention of preterm delivery before 34 weeks of gestation. METHODS AND ANALYSIS This trial is a multicentre, non-blinded, randomised study with 1:1 allocation ratio. The study is conducted at tertiary perinatal care departments in Poland. It will include patients with cervical insufficiency with the fetal membranes visible in the open cervical canal or protruding into the vagina between 16+0 and 23+6 weeks of pregnancy. They will be randomised into two arms: emergency single-level cerclage with vaginal progesterone or double-level cerclage with vaginal progesterone. All will be administered antibiotics and indomethacin. The primary outcome is the rate of deliveries below 34+0 weeks of gestation, while secondary outcomes include gestational age at delivery, neonatal outcomes, maternal outcomes according to the Core Outcome Set for Evaluation of Interventions to Prevent Preterm Birth and cerclage procedure complications. The planned number of participants according to the power analysis is 78. ETHICS AND DISSEMINATION The study protocol was written in accordance with the Standard Protocol Items: Recommendations for Interventional Trials statement. It was created according to the requirements of the Declaration of Helsinki for Medical Research involving Human Subject. Ethical approval was obtained from the Ethics Committee of the Centre of Postgraduate Medical Education (no. 1/2022). The study protocol was approved and published by ClinicalTrials.gov (posted on 24 February 2022). All participants gave a written informed consent. After completion of the study its results will be published in a peer-reviewed English language journal. TRIAL REGISTRATION NCT05268640.

Abstract
In this study, we hypothesized that the changes localized at angiopoietin-2 (ANGPT2), granulocyte-macrophage colony-stimulating factor (CSF2), fms-related tyrosine kinase 1 (FLT1) and toll-like receptor (TLR) 2, TLR6 and TLR9 genes were associated with spontaneous preterm labor (PTL), as well as with possible genetic alterations on PTL-related coagulation. This case-control genetic association study aimed to identify single nucleotide polymorphisms (SNPs) for the aforementioned genes, which are correlated with genetic risk or protection against PTL in Polish women. The study was conducted in 320 patients treated between 2016 and 2020, including 160 women with PTL and 160 term controls in labor. We found that ANGPT2 rs3020221 AA homozygotes were significantly less common in PTL cases than in controls, especially after adjusting for activated partial thromboplastin time (APTT) and platelet (PLT) parameters. TC heterozygotes for TLR2 rs3804099 were associated with PTL after correcting for anemia, vaginal bleeding, and history of threatened miscarriage or PTL. TC and CC genotypes in TLR9 rs187084 were significantly less common in women with PTL, compared to the controls, after adjusting for bleeding and gestational diabetes. For the first time, it was shown that three polymorphisms-ANGPT2 rs3020221, TLR2 rs3804099 and TLR9 rs187084 -were significantly associated with PTL, adjusted by pregnancy development influencing factors.

Abstract
INTRODUCTION The aim of this study was to evaluate whether selected prenatal markers obtained from fetal echocardiography can predict postnatal outcome in congenital diaphragmatic hernia (CDH) patients. We also aimed to verify the prognostic value of lung-to-head ratio (LHR). MATERIAL AND METHODS The study group included 29 fetuses with CDH. We analyzed potentially prognostic parameters measured using fetal echocardiography and fetal ultrasound. The assessed parameters were compared between the group of patients with CDH who survived to discharge (n = 21) and the subset of patients who died before discharge from hospital (n = 8). RESULTS In survivors, mean z-score for ascending aorta (AAo) diameter was 0.23 ±0.98 vs. - 1.82 ±1.04 in patients who died (t-test, p = 0.0015). In survivors, the main pulmonary artery/ascending aorta ratio was 1.22 ±0.17 vs. 1.46 ±0.21 in patients who died (t-test, p = 0.017). In survivors, the LHR was 1.81 ±0.96 vs. 0.95 ±0.6 in patients who died (t-test, p = 0.019). In survivors, the observed to expected LHR was 57 ±30% vs 30 ±18% in patients who died (t-test, p = 0.018). CONCLUSIONS Narrowing of the ascending aorta in CDH fetuses is a poor prognostic factor associated with increased mortality in neonates. Our study also confirmed the prognostic value of LHR.

Abstract
Exposure to environmental factors, such as neurotoxic metals and micronutrients, during critical periods of development can contribute to long-term consequences in offspring's health, including neurodevelopmental outcomes. The aim of this study was to evaluate the association between simultaneous prenatal exposure to metals [lead (Pb), cadmium (Cd), mercury (Hg)] and micronutrients [selenium (Se), zinc (Zn), copper (Cu)] and neurodevelopmental outcomes in school-age children from the Polish Mother and Child Cohort (REPRO_PL). Metals and micronutrients concentrations were measured in cord blood (Pb, Cd, Se, Zn, Cu) and in maternal hair (Hg) collected during the 3rd trimester of pregnancy. Behavioral and emotional problems, as well as children's cognitive and psychomotor development, were assessed in 436 school-age children using the Strengths and Difficulties Questionnaire (SDQ, filled in by the mothers) and the Polish adaptation of the Intelligence and Development Scales (IDS, administered by trained psychologists). Multivariate regression models were applied after imputation of missing values, using two approaches: (i) a joint analysis taking into account all metals and micronutrients simultaneously, and (ii) an ExWAS study (single-exposure model). In the SDQ, Hyperactivity/Inattention problems and Total difficulties were associated with higher Hg concentrations in maternal hair (0.18, 95% CI: 0.05; 0.3; and 0.14, 95% CI: 0.01; 0.3, respectively), whereas Emotional symptoms were inversely associated with Se and Zn levels in cord blood (-0.13, 95% CI: -0.3; 0.004; and -0.10, 95% CI: -0.2; 0.02, respectively). In the IDS, cord blood Pb levels were found to be negatively associated with Fluid and Crystallized IQ (-0.12, 95% CI: -0.3; 0.02; and -0.14, 95% CI: -0.3; 0.007, respectively) as well as Mathematical skills (-0.15, 95% CI: -0.3; 0.01). The current research has been able to simultaneously assess the exposure to various interacting chemicals during the prenatal period. We demonstrate that prenatal co-exposures to Pb, Hg, Zn and Se have long-term influences on the neuropsychological outcome of school-age children.

Abstract
OBJECTIVE Diagnosis of primary hyperaldosteronism in pregnancy is complicated due to lack of reference ranges for aldosterone, renin and aldosterone-to-renin ratio. We have endeavoured to establish third-trimester reference ranges for the above-mentioned parameters. DESIGN & PATIENTS We performed postural tests for aldosterone and renin (chemiluminescence immunoassay Liason® DiaSorin Inc., Italy) in 70 healthy pregnant women (age 30.53±4.51 years), at 32.38±4.25 weeks of gestation and in 22 non-pregnant healthy women (age 33.08±8.72 years). RESULTS Aldosterone reference ranges were 6.51-73.97 ng/dl and 12.33-86.38 ng/dl, for supine and upright positions, respectively and that for renin were 6.25-59.36 µIU/ml and 11.12-82.55 µIU/ml, respectively. Aldosterone and renin concentrations were higher in an upright position (p=0.000459 and p=0.00011, respectively). In contrast, aldosterone-to-renin ratio was not affected by posture (i. e. 0.497-3.084 ng/dl/µIU/ml versus 0.457-3.06 ng/dl/µIU/ml, p=0.12), but was higher (p=0.00081) than in non-pregnant controls. In comparison to manufacturer-provided non-pregnant reference range, supine aldosterone concentrations increased by 556% (lower cut-off) and 313% (upper cut-off), while upright aldosterone concentrations increased by 558% (lower cut-off) and 244% (upper cut-off). The reference range for supine renin concentrations increased by 223% (lower cut-off) and 48.7% (upper cut-off), while upright renin concentrations increased by 253% (lower cut-off) and 79% (upper cut-off). CONCLUSIONS There is an upward shift in aldosterone and renin reference ranges in the third-trimester of pregnancy accompanied by an increase in an aldosterone-to-renin ratio, that is not influenced by posture. It remains to be established whether the aldosterone-to-renin ratio may be used as a screening tool for primary hyperaldosteronism in pregnancy.

Abstract
INTRODUCTION Maternal glycemic state is positively correlated with fetal insulin secretion. Randomized control studies have shown that treatment during pregnancy inhibits to some degree this glycemic effect. Our study aimed to assess fetal pancreas size in a population of treated mothers with gestational diabetes. MATERIAL AND METHODS A cross-sectional, prospective observational study was conducted. Pregnant women at 19-36 weeks of gestation with pre-gestational diabetes receiving insulin therapy or with gestational diabetes receiving either insulin or oral hypoglycemic therapy were recruited. The fetal pancreas circumference was measured and compared to the normal reference range. The Z score of the difference between measured and normal predicted mean pancreas circumference, the regression analysis throughout pregnancy, and the correlation between estimated fetal weight centile and pancreas circumference were calculated. RESULTS Ninety-one women who had gestational diabetes and thirty-four women who had pre-gestational diabetes were included in the study. For both groups, fetal pancreas circumference correlated significantly with abdominal circumference, estimated fetal weight and gestational age. The mean Z score between the predicted pancreas circumference in the group of women diagnosed with gestational diabetes and the predicted pancreas circumference in a normal population peaked at around 24 weeks of gestation (1.1) and decreased gradually afterward to a value of zero at 37 weeks. The mean Z score between the predicted pancreas circumference in the group of women with pre-gestational diabetes and the predicted pancreas circumference in a normal population constantly decreased with duration of pregnancy. It was positive until the 25th week of gestation and then presented negative values towards the term. CONCLUSIONS The presented preliminary data suggest a possible correlation between glycemic control treatment, pancreas size, and gestational age.

High prevalence of early (1st trimester) gestational diabetes mellitus in Polish women is accompanied by insulin resistance similar to women with polycystic ovary syndrome (PCOS). ENDOKRYNOLOGIA POLSKA 2021; 73:1-7. [PMID: 34855192 DOI: 10.5603/ep.a2021.0095] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Accepted: 09/20/2021] [Indexed: 11/25/2022]
Abstract
AIMS Both pregnancy and polycystic ovary syndrome (PCOS) constitute insulin-resistant states that are associated with an increased prevalence of glucose intolerance. Some women demonstrate significant insulin resistance (IR) and develop gestational diabetes (GDM) even in 1st trimester. We compared surrogate IR indices in 1st trimester pregnant women and in women with PCOS (Rotterdam consensus criteria). SUBJECTS & METHODS We performed 75 g Oral Glucose Tolerance Test (OGTT) with insulin measurements in 106 healthy 1st trimester pregnant women at 9.9±2.6 weeks of gestation and in 418 women with PCOS. We assessed IR (HOMA-IR, QUICKI, Matsuda, Belfiore and Stumvoll indices) as well as prevalence of GDM according to the IADPSG and WHO (1999) criteria. RESULTS Despite slightly lower BMI (p=0.027) pregnant women had either similar (QUICKI, Belfiore index, Stumvoll0-120 min) or greater IR than women with PCOS (e.g. HOMA-IR 3.85±6.11 versus 2.64±2.04, p=0.002), while only Matsuda index demonstrated less IR in pregnant women (p=0.003). Correlation between IR indices in pregnant women showed marked variability ranging from r=0.334 (HOMA-IR versus Belfiore index) to r=-1.0 (HOMA-IR versus QUICKI, p<0.001). This was accompanied by high prevalence of GDM (14.2% and 9.4%, IADPSG and WHO criteria, respectively). Women with GDM diagnosed according to IADPSG criteria demonstrated greater IR than pregnant women without GDM. In women with GDM diagnosed according to WHO (1999) criteria these differences were visible only for OGTT-derived IR indices (Belfiore, Matsuda and Stumvoll0-120 index). CONCLUSIONS Depending on the choice of IR indices healthy 1st trimester pregnant women demonstrate either similar, or greater IR than women with PCOS and this is accompanied by high prevalence of early GDM. It remains to be established whether GDM screening should be performed in the 1st trimester.

BMC Pregnancy Childbirth 2021; 21:680. [PMID: 34620125 PMCID: PMC8496087 DOI: 10.1186/s12884-021-04139-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2021] [Accepted: 09/20/2021] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND Although preeclampsia has long been recognized as a condition affecting late pregnancy, little is known of its pathogenesis or treatment. The placenta releases a number of hormones and molecules that influence the course of pregnancy, one of which is chromogranin A, a soluble protein secreted mainly from the chromaffin cells of the adrenal medulla. Its role in pregnancy and pregnancy-related disorders remains unclear. Therefore, the main aim of the proposed study is to determine whether chromogranin A is related with the occurrence of preeclampsia. METHODS Placental samples were collected from 102 preeclamptic patients and 103 healthy controls, and Chromogranin A gene (CHGA) expression was measured using real-time RT-PCR, The RT-PCR results were verified on the protein level using ELISA. The normal distribution of the data was tested using the Shapiro-Wilk test. The clinical and personal characteristics of the groups were compared using the Student's t-test for normally-distributed data, and the χ2 test for categorical variables. The Mann-Whitney U test was used for non-normally distributed data. As the log- transformation was not suitable for the given outcomes, the Box- Cox Transformation was used to normalize data from ELISA tests and CHGA expression. Values of P < .05 were considered statistically significant. RESULTS Chromogranin A gene expression was found to be significantly higher in the study group than in controls. Protein analyses showed that although the CgA concentration in placental samples did not differ significantly, the catestatin (CST) level was significantly lower in samples obtained from women with preeclampsia, according to the controls. CONCLUSIONS FOR PRACTICE This study for the first time reveals that chromogranin A gene expression level is associated with preeclampsia. Moreover, the depletion in catestatin level, which plays a protective role in hypertension development, might be a marker of developing preeclampsia. Further studies may unravel role of Chromogranin A in the discussed disease.

Abstract
The effects of herbicide Roundup (based on glyphosate) on the embryonic development, survival and hatching of common carp (Cyprinus carpio L.) larvae and alteration in foxr1 and hsp70 gene expression were determined. The eggs (obtained from 6 females) were fertilised and incubated in water containing 0; 1 or 10 μl L-1 of Roundup formulation. During early embryonic development (24 and 48 h post-fertilisation - hpf), Roundup caused a statistically important decrease in the embryonic survival rate of common carp. Moreover, retardation of the hatching rate was observed in the group treated with the higher concentration of Roundup at 81 to 99 hpf. At the end of the experiment (99 hpf), an important increase in number of deformed larvae was observed in both groups treated with Roundup in comparison to the control group (52.06; 16.02 and 5.08%, respectively). Significant differences in transcript of the gene foxr1 were found in Roundup-intoxicated groups in comparison to the controls. In the case of hsp70 transcripts, no important changes in exposed groups were observed. These results showed that even small, environmentally relevant amount of Roundup present in the aquatic environment is able to affect the early life stages of common carp and change the transcripts of foxr1, which may have an adverse effect on the later proper development of the reproductive system.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder affecting women of reproductive age. It is characterized by hormonal, reproductive and metabolic disturbances, including hyperandrogenism, altered gonadotropin level, ovarian cysts and ovulatory dysfunction as well as insulin resistance, hyperinsulinemia and dyslipidemia. It was shown that increased insulin concentration is a plausible factor in the pathogenesis of PCOS. Insulin leads to overstimulation of ovarian theca cells to androgen biosynthesis and contributes to insulin resistance in tissues such as muscle, liver, adipose tissue and ovary of PCOS patients. Noteworthy, recent studies suggested that supplementation with vitamin D3 may be an alternative therapy increasing insulin sensitivity and thereby improving reproductive parameters in PCOS women. Indeed, various action of vitamin D3 on the ovarian, hormonal and metabolic features observed in PCOS were presented. Many studies reported therapeutic effects of vitamin D3, but some research found a lack of influence or contradicted these findings. Therefore, the aim of this review was to summarize the available evidence about vitamin D3 and insulin interaction in PCOS, and discusses the potential usefulness of VD3 in PCOS treatment.

Abstract
Economic potential of the swine industry hinges upon the reproductive performance of sows, which may be enhanced by improving uterine capacity, a component trait of litter size and piglet productivity. Previous attempts at characterising morphological traits indicative of high uterine volume have not been completely successful, resulting in the continued need for a reliable method of predicting reproductive value to improve production efficiency of the sow. Hence, the main objective of this study was to scrutinize macro- and micro-morphology of the sow’s reproductive tract for quantitative correlations with fertility indices. Reproductive records from Polish Landrace×Polish Large White sows (mean±s.e.m. parity: 4.3±0.6, range: 2–8) were used to examine the associations between fertility and ovarian/uterine morphology (n=34) or uterine histomorphometry (n=10) posthumously. Simple linear regression was performed to determine the relationship between anatomical or histological parameters and various measures of reproductive performance. Several measures related to the ovary, including right and left ovarian weight (r=0.50, P=0.005, and r=0.49, P=0.006, respectively), were positively correlated with the litter size, whereas left ovarian number of corpora lutea (r=−0.38, P=0.04) was negatively correlated with the mean litter size. Analysis of histomorphological characteristics of the uterine wall collected during the luteal phase of the oestrous cycle revealed correlations between mean litter size and myometrial vascular content (r=0.75, P=0.03), the proportion of myometrial stroma (r=−0.68, P=0.03), and the variability of endometrial thickness (r=−0.72, P=0.02) in sows. Eight ovarian, vaginal, and uterine characteristics were significantly correlated with mean lifetime numbers of live born and stillborn piglets/litter or the last litter size before slaughter. In conclusion, several anatomical and histomorphological metrics that relate to reproductive performance of swine may be used to inform production protocols and as a tool for selection of elite breeding sows, warranting future research into noninvasive or minimally invasive techniques for obtaining such measures.

Abstract
INTRODUCTION The fetal thymus may be visualized using ultrasonography (USG) and is typically located in the mediastinum. In the past years, the size of the fetal thymus has served not only as a marker of genetic or heart defects but also as a predictive factor for intrauterine growth restriction, premature birth, preeclampsia, chorioamnionitis or even neonatal sepsis. MATERIAL AND METHODS A total of 410 fetuses were qualified for the study. Fetuses with heart defects were excluded from the study. The fetal thymus was evaluated with ultrasonography between the 14th and 40th week of gestation. After obtaining a standard transverse view encompassing the three great vessels, thymus measurements were attempted, i.e. maximal transverse diameter, circumference and surface area. Linear regression was used for statistical analysis, yielding 3 models, each with a different dependent variable. The confidence interval for each model was set at 80% to aid the comparison with centile grid growth charts for neonates and children. The test was regarded as statistically significant when p < 0.05. RESULTS From a total of 410 fetuses the thymus transverse diameter, circumference and area were successfully measured in 410, 320 and 330 cases, respectively. The probabilities are lower than 0.0005 for each model, which means that each model is quite statistically significant. CONCLUSIONS The coverage of healthy thymus nomograms in the fetal population may be the basis for the identification of fetuses at risk of hypoplasia or thymic hyperplasia, which seems particularly important from the point of view of the detection of potential inborn immunological disorders.

Subclinical thyroid dysfunction in the first trimester of pregnancy: 'Disease' versus physiological (pulsatile) variation in TSH concentrations. Clin Endocrinol (Oxf) 2020; 93:739-745. [PMID: 32430942 DOI: 10.1111/cen.14256] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2020] [Revised: 04/21/2020] [Accepted: 04/23/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND There is no universal consensus regarding cut-off points for TSH in pregnancy, so concentrations of 2.5 or 4.0 mIU/L were suggested for first trimester (Endocrine Society [2012] and ATA [2017] guidelines, respectively). Yet, the impact of physiological variation in TSH secretion has not been assessed. SUBJECTS AND METHODS We assessed baseline concentrations of free T4, free T3 and TSH at 30-minute intervals (between 7.00 and 9.00 hours) in 110 healthy pregnant women, age 30.2 ± 6.0 years, 9.9 ± 2.4 weeks of gestation, and in 19 female controls, age 28.9 ± 10.7. RESULTS Mean TSH concentrations in pregnant women were 1.62 ± 1.26 mIU/L and on average varied by 39.5% (dispersion between the highest and the lowest TSH), with no difference in TSH variation between pregnant women and controls. Taking into account the highest TSH out of five consecutive measurements, TSH >2.5 mIU/L and TSH above 4.0 mIU/L were found in 23 (20.9%) and 10 (9.1%) pregnant women, respectively. In contrast, when the lowest TSH value was considered, then concentrations of TSH >2.5 mIU/L and >4.0 mIU/L were found in 14 (12.7%) and 4 (3.6%) women, respectively. This discrepancy was even more pronounced in aTPO-negative subjects (21 [21.2%] vs 8 [8.1%] women, for TSH >2.5 mIU/L, and six [6.06%] vs one [1.01%], for TSH >4.0 mIU/L). Furthermore, either six (5.4%) or 10 (9.1%) women had TSH concentrations below 0.1 mIU/L. CONCLUSIONS In a significant number of patients, diagnosis of subclinical thyroid dysfunction could be erroneously made not as a result of 'disease', but as a result of physiological variation in TSH concentrations.

Abstract
Children born small for gestational age (SGA) are at increased risk of future glucose intolerance and type 2 diabetes, possibly after due intrauterine metabolic programming. Soluble leptin receptor (SLR) limits leptin access to signal-transducing membrane receptors. The present study examines whether SGA and appropriate for gestational age (AGA) twins differ with regard to their C-peptide, glucose and leptin systems. The markers C-peptide, glucose, fetal leptin, and SLR in cord blood were assessed in children from dichorionic twin pregnancies at delivery. In 32 cases, weight differed by >15% between twins: one demonstrated Intrauterine Growth Retardation (IUGR) (<10th percentile-SGA), while the other did not (AGAI). The other 67 pairs presented appropriate weight for gestational age (AGAII). Placental leptin and placental leptin receptor content were also assessed. Despite the same concentrations of glucose, the SGA twins maintained a higher level of C-peptide [44.48 pmol/l vs. 20.91 pmol/l, p < 0.05] than the AGAI co-twins, higher HOMA index, calculated as [C-peptide] x [Glucose] (p = 0.045), in cord blood, and a higher level of SLR [SGA vs AGAI—mean: 28.63 ng/ml vs. 19.91 ng/ml, p < 0.01], without any differences in total leptin (p = 0.37). However, SGA placentas demonstrated higher leptin level [130.1 pg/100 g total protein vs 83.8 pg/100 g total protein, p = 0.03], without differences in placental leptin receptor (p = 0.66). SGA/IUGR twins demonstrate relative insulin resistance accompanied by decreased fetal and increased placental leptin signaling. We speculate that relative insulin resistance and changes in the leptin system might be the first evidence of processes promoting deleterious metabolic programming for post-natal life.
