Introduction: Preservation of reproductive function is a key concern for many premenopausal women with breast cancer, given the known gonadotoxic effects of treatments. The present systematic review aimed to investigate the effectiveness and safety of fertility preservation strategies in pre-menopausal women with breast cancer.

Methods: Primary research assessing fertility preservation strategies of any type was identified.

Background: The use of peri-implantation glucocorticoids has been advocated to improve embryo implantation during assistive reproductive technology (ART) cycles such as in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI). It has been proposed that glucocorticoids may improve the intrauterine environment by acting as immunomodulators to reduce the uterine natural killer (NK) cell count and activity, normalising the cytokine expression profile in the endometrium and by suppression of endometrial inflammation.

Objectives: To evaluate the effectiveness and safety of glucocorticoids versus no glucocorticoids administered around the time of anticipated implantation in women undergoing IVF or ICSI.

Background: Several interventions and techniques are suggested to improve the outcome of embryo transfer (ET) in assisted conception. However, there remains no consensus on the optimal practice, with high variations among fertility specialists.

Objective And Rationale: We conducted a comprehensive systematic review and meta-analyses of randomized controlled trials (RCTs) aiming to identify effective interventions that could be introduced around the time of ET to improve reproductive outcomes.

Objectives: In bladder drainage, an essential part of post-hysterectomy care, the optimal timing for removing the urinary catheter is unclear. Our objective was to evaluate the risks and benefits of early (<6 h) vs delayed (>6 h) catheter removal post-hysterectomy.

Study Design: A systematic review searching MEDLINE, EMBASE and Cochrane CENTRAL from inception till May 2019 for randomised trials of women undergoing hysterectomy.

Background: Ovarian response to stimulation during in-vitro fertilisation (IVF) and intra-cytoplasmic sperm injection (ICSI) plays an important role in determining live birth rates. Adjuvant treatments during ovarian stimulation that have different modes of action have been used to improve ovarian response to stimulation and outcome of IVF. Glucocorticoids (GCs) are a class of steroid hormones that have been used either alone or in combination with other stimulatory regimens in order to improve folliculogenesis and pregnancy rates.

A 36-year-old woman was referred by general practitioner to the early pregnancy unit with pelvic pain in her seventh week of pregnancy. She had a transvaginal ultrasound. Unruptured live twin tubal ectopic pregnancy was diagnosed on.

Background: In order to improve embryo implantation for in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) cycles the use of glucocorticoids has been advocated. It has been proposed that glucocorticoids may improve the intrauterine environment by acting as immunomodulators to reduce the uterine natural killer (NK) cell count and normalise the cytokine expression profile in the endometrium and by suppression of endometrial inflammation.

Objectives: To investigate whether the administration of glucocorticoids around the time of implantation improved clinical outcomes in subfertile women undergoing IVF or ICSI when compared to no glucocorticoid administration.

Objective: Acute-phase Serum Amyloid A (ASAA) is a novel pro-inflammatory adipokine, increased in obese, insulin resistant subjects. Polycystic ovary syndrome (PCOS) is associated with inflammation and atherosclerosis. We assessed sera, adipose tissue (AT) mRNA and protein levels of ASAA of PCOS women and matched controls.

Objective: Polycystic ovary syndrome (PCOS) is associated with insulin resistance and obesity. Vaspin (visceral adipose tissue-derived serine protease inhibitor) levels increase with hyperinsulinemia and obesity. Currently, no data exists on vaspin in PCOS women.

Context: Polycystic ovary syndrome (PCOS) is a multifaceted metabolic disease linked with insulin resistance (IR) and obesity. Recent studies have shown that plasma levels of the insulin-mimetic adipokine visfatin increase with obesity. Currently, no data exist on the relative expression of visfatin in either plasma or adipose tissue of PCOS women.

Purpose: Chronological age, or biological age as indicated by elevated FSH levels, are related to ovarian reserve. This study addresses the likelihood of cancellation of IVF treatment due to a poor ovarian response utilising both basal serum FSH and woman's age.

Methods: A prospective cohort of 536 infertile but ovulating women were studied in their first cycle of IVF treatment.

Acquired haemophilia was diagnosed following detailed investigation of a post-partum haemorrhage unresponsive to standard management. Circulating factor VIII inhibitors and low factor VIII levels were detected and intravenous DDAVP treatment lead to a resolution of symptoms. This case highlights the importance of haematological investigations in persisting post-partum haemorrhage.

A 46-year-old woman with a triplet pregnancy developed seizures, an oculogyric crisis and a homonymous hemianopia post-natally. Abnormal neuroimaging studies and lumbar puncture suggested possible cerebral vasculitis. Treatment with aciclovir and prednisolone resulted in a slow resolution of symptoms.

Poor ovarian response to gonadotrophin stimulation represents a clinical problem in in vitro fertilization practice. Women showing poor ovarian response are a heterogeneous group, many of whom have a reduced ovarian reserve and consequently a lower pregnancy potential. Various management strategies have been proposed to improve ovarian response to gonadotrophins, but these have met with limited success.
