Incidence of Cardiovascular Instability in Patients With Guillain-Barré Syndrome: A Retrospective Study.

Introduction Guillain-Barré syndrome (GBS) is an autoimmune disease affecting radicles and peripheral nerves resulting in acute flaccid paralysis. Respiratory failure, autonomic dysfunction, and secondary complications such as pneumonia, and venous thromboembolism are the major causes of death and disability in GBS. Cardiovascular complications play a major role in the prognosis of GBS patients.

Exophytic Subserosal Uterine Adenomyomatous Polyp Mimicking Malignancy: A Case Report.

The epidemiological profile of adenomyosis has drastically changed in recent years due to advancements in imaging techniques. Even though adenomyosis is not uncommon in women of childbearing age, we present an intriguing case of a 30-year-old woman with long-standing progressive dysmenorrhea and infertility who had a posterior wall exophytic adenomyomatous polyp with full-thickness pseudo-invasion out of the uterine serosa into the right ovarian endometriotic cyst, mimicking malignancy. After surgical excision, the patient spontaneously conceived and delivered a live-term baby, soon after which she experienced an early recurrence.

The comparison of Y chromosome microdeletion incidence in blood DNA and sperm cell DNA.

Background: During gamete development and spermatogenesis, certain genes on the Y chromosome (Yq) in the Male-Specific Region (MSR) are responsible for human gametes formation. The long arm Yq is composed of both euchromatin and the genetically inactive heterochromatin regions. This region contains the Azoospermia factors AZFa, AZFb and AZFc.

Dual extrauterine ectopic pregnancy: double management.

A 30-year-old nulliparous woman was referred with suspected left ovarian ectopic pregnancy. She had undergone laparoscopic left salpingectomy for ruptured tubal ectopic pregnancy 3 weeks earlier, following treatment with medications for ovulation induction. Sonological examination revealed a left ovarian ectopic pregnancy corresponding to 8 0/7 weeks with cardiac activity.

ASN007 is a selective ERK1/2 inhibitor with preferential activity against RAS-and RAF-mutant tumors.

Inhibition of the extracellular signal-regulated kinases ERK1 and ERK2 (ERK1/2) offers a promising therapeutic strategy in cancers harboring activated RAS/RAF/MEK/ERK signaling pathways. Here, we describe an orally bioavailable and selective ERK1/2 inhibitor, ASN007, currently in clinical development for the treatment of cancer. In preclinical studies, ASN007 shows strong antiproliferative activity in tumors harboring mutations in BRAF and RAS (KRAS, NRAS, and HRAS).

ASN004, A 5T4-targeting scFv-Fc Antibody-Drug Conjugate with High Drug-to-Antibody Ratio, Induces Complete and Durable Tumor Regressions in Preclinical Models.

The 5T4 oncofetal antigen (trophoblast glycoprotein) is expressed in a wide range of malignant tumors but shows very limited expression in normal adult tissues. ASN004 is a 5T4-targeted antibody-drug conjugate (ADC) that incorporates a novel single-chain Fv-Fc antibody and Dolaflexin drug-linker technology, with an Auristatin F hydroxypropylamide payload drug-to-antibody ratio of approximately 10-12. The pharmacology, toxicology, and pharmacokinetic properties of ASN004 and its components were investigated and ASN004 showed high affinity for the 5T4 antigen and was selectively bound to and internalized into 5T4-expressing tumor cells, and potent cytotoxicity was demonstrated for a diverse panel of solid tumor cell lines.

Exclusive use of intrasac potassium chloride and methotrexate for treating cesarean scar pregnancy: effectiveness and subsequent fecundity.

Study Question: Is exclusive use of intragestational sac potassium chloride (KCl) and methotrexate (MTX) effective in the management of viable cesarean scar pregnancy (CSP)?

Summary Answer: Exclusive use of intragestational sac KCl and MTX was effective in the management of viable CSP.

What Is Known Already: Owing to a paucity of randomized studies on management of CSP, evidence-based management remains unclear. Intragestational sac KCl or MTX along with either systemic MTX or surgical intervention, such as uterine artery embolization or dilation and curettage, has proved to be effective in the management of CSP.

Background: Progressive Muscle Relaxation (PMR) helps to improve the emotional state of antenatal mothers with stress and anxiety, which is necessary to keep the fetus healthy inside the womb. This study assesses the efficacy of progressive muscle repose on stress and anxiety among primigravidae.

Materials And Methods: A randomized controlled study was conducted from May 2015 to June 2017 with 250 primigravidae.

Association of estrogen, progesterone and follicle stimulating hormone receptor polymorphisms with in vitro fertilization outcomes.

Unlabelled: Despite the advances in in vitro fertilization (IVF), the implantation success rate for infertile women remains approximately only 15%. In this study, we sought to determine whether implantation failure after repeated IVF treatments is influenced by the presence of common variants in estrogen α, progesterone and follicle stimulating hormone receptor genes. The study population included three groups of women: group 1 were 50 women who had the transfer of ≥3 high-quality embryos during the IVF procedure without ever having had a clinical pregnancy; group 2 were 50 women who achieved a clinical pregnancy after ≤3 high-quality embryos transfers and group 3 were 50 control subjects who achieved a clinical pregnancy without any fertility therapy that resulted in a one live-born infant.

Does Pretrigger Echogenic Endometrium in Assisted Reproductive Technology Cycles Reflect Raised Serum Progesterone Level?

Background: Serum progesterone is the main hormone of the luteal phase. The hyperechoic pattern of the endometrium in the luteal phase is believed to be induced by raised serum progesterone. Serum progesterone is found to be raised cases of controlled ovarian stimulation (COS) cycle on the day of ovulation trigger.

Correlation of serum estradiol level on the day of ovulation trigger with the reproductive outcome of intracytoplasmic sperm injection.

Background: Serum estradiol (E2) levels are measured in in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI), to assess the ovarian response and to predict ovarian hyperstimulation syndrome. The impact of peak E2 levels on IVF-ICSI outcome was found to be inconsistent in the previous studies.

Aim: To evaluate the impact of the serum E2 levels on the day of ovulation trigger with the reproductive outcome of ICSI.

Pregnancy outcome of assisted reproductive technology cycle in patients with hypogonadotropic hypogonadism.

Context: Ovulation induction in patients with hypogonadotropic hypogonadism (HH) is a challenge to the treating physician. The threshold for ovarian response in HH may differ substantially from that of normal patients. To reach that threshold levels of follicle stimulating hormone, in a step-up protocol longer duration of stimulation is required in some cases so as to prevent multiple pregnancy and to eliminate the risk of ovarian hyperstimulation syndrome.
