Acyl Ghrelin

Ghrelin is a pleiotropic hormone that governs eating and energy equilibrium as well as promotes the release of growth hormone release. Although cord blood ghrelin has been correlated to the weight at birth and other anthropometric measures, the implication of des-acyl ghrelin in fetal and postnatal growth still not well understood. The goal of this research was to investigate the concentration of des-acyl ghrelin (DAG) in cord blood of appropriate for gestational age (AGA), small for gestational age (SGA) and large for gestational age (LGA) infants in order to elucidate their correlation with birth weight, anthropometric measures as well as apgar score of the newborn and relating them to maternal DAG levels. Cord blood specimens were procured from 25 SGA, 24 AGA infants and 25 LGA infants. Desacyl ghrelin, was quantified by ELIZA. A significant negative correlation has been found between cord ghrelin and neonatal anrthropometric measures( neonatal weight, height, head circumference, mean arm circumference) As well, a significant negative correlation has been detected between cord ghrelin and apgar score at 1 and 5 min. The current results shed the light on the critical role of DAG in the growth during the intrauterine period. Further studies are necessary to identify the exact mechanisms underlying the contribution of DAG in the growth of the fetus.

Background. It is unknown whether the presence of Plasmodium falciparum malaria parasites in umbilical cord blood denotes activation of complement and oxidative stress to affect the duration of pregnancy and birth weight. Methods. In a cross-sectional study conducted from January to April 2019 in Bamenda, Cameroon, cord blood samples were collected from 300 women at delivery. Parasitaemia was determined microscopically. Babies’ weight and age of gestation were recorded. Plasma levels of complement and oxidative stress were measured by specific tests. Results. Cord blood malaria prevalence was 21.33%. Babies with an infected cord showed a low birth weight and gestation age than those with uninfected cords. More babies with infected cords had LBW (6.25%) compared to the counterparts (5.50%). The levels of parasitaemia and the babies’ weight showed a weak positive correlation. The prevalence of preterm and postterm birth was 4.33% and 24.33% respectively, with a weak negative correlation between the age of gestation and the umbilical cord parasitaemia. There was correlation between cord parasitaemia and levels of complement haemolytic activity titter (CH50) and specific classical pathway activity (CPA) in cord blood. CH50 and CPA levels, however, were significantly higher in infected cord blood samples, compared with uninfected cord blood samples. CH50 showed a negative correlation with the birth weight and gestational age in infected cord blood samples. The levels of total oxidative stress (TOS) and total antioxidant defense were significantly lower in infected cord blood than uninfected. TOS displayed a positive correlation with the density of parasitaemia and a weak negative correlation with the birth weight and gestational age in infected cord blood. Conclusion. Cord blood infection lowers the complement haemolytic titter, oxygen radicals and total antioxidant defense in neonates. This lowering of complement haemolytic titter and oxygen radical compounds in umbilical cord malaria are associated with low birth weight and preterm birth.

ABSTRACT Context Prenatal androgen excess can cause a phenocopy of polycystic ovary syndrome (PCOS) in mammals. Retrospective studies have suggested that girls at risk for PCOS have low birth weight and prospective studies have suggested an increased prevalence of small for gestational age offspring in women with PCOS. Objective To determine whether infants of women with PCOS have reduced birth weight or increased intrauterine androgen levels. Design Prospective case-control study. Participants Thirty-nine PCOS and 31 control women and their infants. Main outcome measures Birth weight and mixed cord blood testosterone, androstenedione (A), dehydroepiandrosterone, 17-hydroxyprogesterone, estradiol (E2), and dihydrotestosterone levels. Results Mean birth weight did not differ but there was a significant increase in the prevalence of large for gestational age infants in the PCOS group. Cord blood E2 and A levels were lower (p < 0.05) but testosterone:E2 ratios did not differ in female PCOS compared to control offspring. There was no difference in E2 and A levels in the male PCOS and control offspring. There was no difference in 17-hydroxyprogesterone or in other androgen levels in either male or female PCOS offspring compared to their respective control group. Conclusion Infants of women with PCOS were more likely to be large for gestational age. Female offspring of affected women have lower cord blood A levels; other cord blood androgen levels do not differ compared to female control offspring. Cord blood E2 levels are also significantly decreased in PCOS, without any difference in the testosterone:E2 ratio, suggesting decreased fetal or placental production of steroids.

Ischemic Encephalopathy

Background: Hypoxic ischemic encephalopathy (HIE) is a serious condition which results in neonatal morbidity and mortality. Early prediction of HIE especially in the first six hours of birth leads to early treatment with better prognosis. Aim: The aim of this study was to compare the concentrations of leptin, adiponectin, and erythropoietin between normal neonates and those with HIE for the possible use of these markers for assessment of the degree of HIE and as markers for early prediction of HIE. Patients and Methods: This study was carried out on 50 appropriate for gestational age (AGA) neonates with HIE born in Tanta University Hospital during the period from June 2016 to March 2018 (Group I). This study also included 50 appropriate for gestational age (AGA) normal neonates not suffering from any complications and matched with group I in age and sex as a control group (Group II). For all neonates in both groups, the following were done: Complete prenatal, natal, and postnatal history, assessment of APGAR score at 5 and 10 minutes, complete clinical examination with special account on clinical evidence of encephalopathy including hypotonia, abnormal oculomotor or pupillary movements, weak or absent suckling, apnea, hyperpnea, or seizures, measurement of cord blood gases and measurement of serum erythropoietin, leptin and adiponectin levels by ELISA immediately after birth. Results: There were no significant differences between Group I and Group II regarding gestational age, male to female ratio, mode of delivery, and weight while there were significant differences regarding Apgar score at 1 and 5 minutes with significantly lower Apgar score at 1 and 5 minutes in group I compared with Group II. There were significantly lower cord blood PH and adiponectin level and significantly higher cord blood Leptin and erythropoietin in group I compared with group II. There were significant differences between cord blood adiponectin, leptin, erythropoietin, and PH in different degrees of HIE with significantly lower cord blood adiponectin and PH and significantly higher cord blood leptin and erythropoietin in severe degree of hypoxia compared with moderate degree and in moderate degree compared with mild degree of hypoxia. There was a significant positive correlation between cord blood erythropoietin and leptin and a significant negative correlation between cord blood erythropoietin and both adiponectin and PH in studied neonates with hypoxia. ROC curve showed that EPO had the best sensitivity and specificity followed by leptin then adiponectin while the PH had the least sensitivity and specificity as early predictors of hypoxic neonates. Conclusion and Recommendations: Neonates with HIE had lower cord blood PH and adiponectin levels and higher leptin and erythropoietin levels than normal healthy neonates at birth and during the early postnatal period. The significant differences between cord blood erythropoietin, leptin, and adiponectin between neonates with hypoxia compared with normal neonates may arouse our attention about the use of these markers in the cord blood as early predictors of neonatal HIE which can lead early treatment and subsequently better prognosis.

AbstractThis study was planned to investigate the relationship between birth weight and insulinlike growth factor-I (IGF-I),IGF binding protein-3 (IGFBP-3), and leptin levels in neonates with normal growth (appropriate for gestational age: AGA) and retarded growth (small for gestational age: SGA); and to evaluate these growth factors’ effects in early postnatal growth. All newborns were full-term: gestational age 38-41 weeks. Of 50 neonates, 25 were SGA. IGF-I, IGFBP-3 and leptin levels were measured in maternal serum and venous cord blood at birth and at 15 days of life of neonates using specific RIAs. Maternal serum leptin concentrations were significantly higher than cord blood leptin concentrations (p <0.001). Maternal serum IGF-I, IGFBP-3 and leptin levels did not show correlations with birth weight. In contrast, there were significantly positive correlations between birth weight and venous cord blood IGF- I, IGFBP-3 and leptin levels (p <0.001). In the SGA group, the newborns with a slow postnatal growth pattern had lower umbilical cord serum IGF-I levels compared with newborns with a normal growth pattern. A similar result was also found in the AGA group. Similar results were not found for serum leptin and IGFBP-3.In conclusion, cord blood IGF-I, IGFBP-3 and leptin levels play an important role in the regulation of fetal and neonatal growth. It is likely that IGF-I has a more important role than the other factors in early postnatal growth.

There was no difference in 17-hydroxyprogesterone or other androgen levels in either male or female PCOS offspring compared with their respective control group. Conclusion: Infants of women with PCOS were more likely to be large for gestational age. Female offspring of affected women have lower cord blood A levels; other cord blood androgen levels do not differ compared with female control offspring. Cord blood E2 levels are also significantly decreased in PCOS, without any difference in the testosterone to E2 ratio, suggesting decreased fetal or placental production of steroids.

Papillary Thyroid

Although papillary thyroid cancer (PTC) is curable with excellent survival rate, patients with dedifferentiated PTC suffer the recurrence or death. As cancer immune escape plays a critical role in cancer progression, we aimed to investigate the relationship between differentiation and immune landscape of PTC and its implications for immunotherapy. Using The Cancer Genome Atlas data, we estimated the immune cell enrichment scores and overall immune infiltration, ImmuneScore, to characterize the immune landscape of PTC. Thyroid differentiation score (TDS) was calculated from 16 thyroid function genes. We demonstrated that ImmuneScore had a significant negative correlation with TDS, and BRAFV600E+ tumors showed significantly low TDS and high ImmuneScore. Enrichment scores of myeloid cells and B-cells were negatively correlated with TDS, while those of plasma cells were positively correlated with TDS. In addition, the association between TDS, ImmuneScore and immunosuppressive markers (CTLA-4, PD-L1, HLA-G) were evaluated according to BRAFV600E status. All immunosuppressive markers expression had a significant negative correlation with TDS, and they were significantly higher in BRAFV600E+ status. Subgroups were divided by median values of TDS and ImmuneScore, and immunosuppressive markers of these subgroups were compared. The immunosuppressive markers expression was the highest in high ImmuneScore and low TDS subgroup. Furthermore, ImmuneScore had a significant association with recurrence-free survival, irrespective of clinicopathologic factors including BRAFV600E status. These findings based on gene expression data illuminate the immune landscape of PTC and its association with TDS, immunosuppressive markers and recurrence. Our results would be extended to investigate immunotherapeutic approaches in PTC.
