Beta human chorionic gonadotrophin

Sofia Andrade de Oliveira, Vinícius Fernando Calsavara, Gemma Castillón Cortés
Final oocyte maturation with Human Chorionic Gonadotropin (hCG) and ovarian stimulation with Follicle Stimulation Hormone (FSH) combined with Gonadotrophin-releasing Hormone (GnRH) antagonist to block Luteinizing hormone (LH) surge is a standard procedure of in vitro Fertilization (IVF) and Intracytoplasmic Sperm Injection (ICSI). However, GnRH agonist has been replacing the use of hCG in certain situations, especially in patients at risk of Ovarian Hyperstimulation Syndrome (OHSS). Some studies have also shown advantages in the combined use of GnRH agonist concurrently with hCG in inducing final oocyte maturation, a treatment known as "Dual Trigger"...

STUDY QUESTION: Are maternal first trimester levels of serum free-beta hCG associated with the development of hypospadias or undescended testis (UDT) in boys? SUMMARY ANSWER: Overall, first trimester maternal levels of serum free-beta hCG are not associated with hypospadias or UDT. However, elevated levels were found in severe phenotypes (proximal hypospadias and bilateral UDT) suggesting an altered pathway of hormonal release in early pregnancy. WHAT IS KNOWN ALREADY: Human chorionic gonadotrophin peaks in first trimester of pregnancy stimulating fetal testosterone production, which is key to normal male genital development...

BACKGROUND: Down's syndrome occurs when a person has three copies of chromosome 21, or the specific area of chromosome 21 implicated in causing Down's syndrome, rather than two. It is the commonest congenital cause of mental disability and also leads to numerous metabolic and structural problems. It can be life-threatening, or lead to considerable ill health, although some individuals have only mild problems and can lead relatively normal lives. Having a baby with Down's syndrome is likely to have a significant impact on family life...

BACKGROUND: Non-seminomatous germ cell tumours make up about 40 % of all germ cell tumours, which in turn are the most common tumours in men aged 15-44 years. Low risk stage I non-seminomatous germ cell tumours, which are confined to the testes, are commonly treated by orchiectomy and surveillance. Up to 20 % of patients with this diagnosis relapse, usually within 1-2 years of follow up, but very rarely after more than 5 years. The most common sites of relapse are the retroperitoneal lymph nodes, the mediastinum, and the lungs...

We report a spontaneous unilateral live tubal twin pregnancy in a patient with a history of previous ectopic pregnancy (EP) and tubal surgery. Transvaginal ultrasound showed one pregnancy sac containing two fetal poles with cardiac activity, which appeared to be sited within the right adnexum. The right tubal EP was removed by salpingectomy. Ultrasound findings of suspected adnexal mass and free liquid in the Douglas pouch along with an increased a beta-human chorionic gonadotrophin levels, especially in association of risk factors, can help the early diagnosis of EP and reduce the related mortality and morbidity...

Abnormal trophoblast function is associated with fetal growth restriction (FGR). The JAK-STAT pathway is one of the principal signalling mechanisms by which cytokines and growth factors modulate cell proliferation, differentiation, cell migration and apoptosis. The expression of placental JAK-STAT genes in human idiopathic FGR is unknown. In this study, we propose the hypothesis that JAK-STAT pathway genes are differentially expressed in idiopathic FGR-affected pregnancies and contribute to abnormal feto-placental growth by modulating the expression of the amino acid transporter SNAT2, differentiation marker CGB/human chorionic gonadotrophin beta-subunit (β-hCG) and apoptosis markers caspases 3 and 8, and TP53...

INTRODUCTION: Despite the major advances made in the diagnosis and management of ectopic pregnancies in the last two decades, an accurate diagnosis can sometimes still be quite challenging, since it relies on the combination of ultrasound findings and serial serum beta-human chorionic gonadotrophin (β-hCG) measurements. CASE PRESENTATION: This paper describes the case of a 36-year-old woman of Caucasian origin who was admitted to the emergency department of our clinic with clinical symptoms of hemorrhagic shock in combination with two negative pregnancy tests done by her at home and a negative urine test which was performed on her admission to the hospital...

OBJECTIVE: To determine whether embryos having all top qualified both on Day 3 and Day 5 have higher pregnancy rates than the oth- ers. MATERIALS AND METHODS: The study included 143 consecutive cycles were recruited in which Day 5 embryo transfer was available. Cleavage stage embryos were graded according to 1 to 4 scoring system, based on fragmentation, cell symmetry, and blastomere num- ber. Among cleavage stage embryos, Grade 1 and Grade 2a/2b were further stratified as 'top quality' embryos to be transferred, others were defined as control group...

STUDY QUESTION: Does substituting 150 µg corifollitropin alfa for 450 IU follitropin beta during the first 7 days of ovarian stimulation in proven poor responders, result in retrieval of a non-inferior number (<1.5 fewer) of cumulus oocyte complexes (COCs)? SUMMARY ANSWER: A single s.c. dose of 150 µg corifollitropin alfa on the first day of ovarian stimulation, followed if necessary, from Day 8 onwards, with 450 IU of follitropin beta/day, is not inferior to daily doses of 450 IU follitropin beta...

OBJECTIVE: The aim of this article is to develop the best first-trimester screening model for preeclampsia (PE) based on maternal characteristics, biophysical parameters, and angiogenic factors in a low-risk population. METHODS: A prospective cohort of 9462 pregnancies undergoing first-trimester screening is used. Logistic regression predictive models were developed for early and late PE (cut-off of 34 weeks' gestation at delivery). Data included the a priori risk (maternal characteristics), mean arterial pressure (MAP), and uterine artery (UtA) Doppler (11-13 weeks) in all cases...
