To assess ovarian reserve (OVR) by means of follicle-stimulating hormone (FSH), anti-Müllerian hormone (AMH), and antral follicle count (AFC) measurement in eumenorrheic women with breast cancer, exposed to gonadotoxic chemotherapy. Fifty-two women (35.3 ± 3.8 years old) with breast cancer and undergoing cyclophosphamide-containing chemotherapy were enrolled. The assessment was performed before chemotherapy (T1) and after 2 (T2) and 6 months (T3). Six months after chemotherapy, the prevalence of regular cycles was 60%. Anti-Müllerian hormone decreased down to undetectable levels at T2 and T3 (T1: 2.53 [1.00-5.31]; T2 < 0.08; T3: < 0.08 [< 0.08-1.07] ng/mL), ( < 0.0001). Antral follicle count was 11 [8.0-13.5] follicles at T1 and lower at T2 (5.50 [3.75-8.0] and T3 (5.0 [2.5-7.0]) ( < 0.0001). In patients who remained with regular cycles during chemotherapy or resumed normal menses, FSH and estradiol levels remained unchanged. Anti-Müllerian hormone and AFC are useful as markers of OVR decline in women exposed to chemotherapy. Follicle-stimulating hormone is only adequate in women who become amenorrheic.

Iatrogenic cerebral amyloid angiopathy, a disease caused by contact with neurosurgical material or human growth hormone contaminated by beta-amyloid peptide (Aβ), has a prion-like transmission mechanism. We present a series of three patients under 55 years of age who underwent cranial surgery. All of them developed multiple cerebral hemorrhages, transient focal neurological deficits, and/or cognitive impairment after 3-4 decades.

Study Question: Are live birth rates (LBRs) per woman following flexible progestin-primed ovarian stimulation (fPPOS) treatment non-inferior to LBRs per woman following the conventional GnRH-antagonist protocol in expected suboptimal responders undergoing freeze-all cycles in assisted reproduction treatment?
Summary Answer: In women expected to have a suboptimal response, the 12-month likelihood of live birth with the fPPOS treatment did not achieve the non-inferiority criteria when compared to the standard GnRH antagonist protocol for IVF/ICSI treatment with a freeze-all strategy.
What Is Known Already: The standard PPOS protocol is effective for ovarian stimulation, where medroxyprogesterone acetate (MPA) is conventionally administered in the early follicular phase for ovulatory suppression. Recent retrospective cohort studies on donor cycles have shown the potential to prevent premature ovulation and maintain oocyte yields by delaying the administration of MPA until the midcycle (referred to as fPPOS), similar to GnRH antagonist injections.

Treatment for major depressive disorder (depression) often has partial efficacy and a large portion of patients are treatment resistant. Recent studies implicate reduced somatostatin (SST) interneuron inhibition in depression, and new pharmacology boosting this inhibition via positive allosteric modulators of α5-GABAA receptors (α5-PAM) offers a promising effective treatment. However, testing the effect of α5-PAM on human brain activity is limited, meriting the use of detailed simulations.

Background: Pain in people with cerebral palsy (CP) has been classically underestimated and poorly treated, particularly in individuals with impaired communication skills.
Objective: To analyze changes in different salivary metabolites and pain behavior scales after a painful procedure in adults with CP and adults with typical development.
Methods: Salivary levels of sTNF-α, sIgA, Cortisol, FRAP, ADA and Alpha Amylase, as well as 3 observational pain scales (Wong-Baker, Non-Communicating Adults Pain Checklist and Facial Action Coding System) were assessed before and after an intramuscular injection in 30 Individuals with CP and 30 healthy controls.

Osteoporosis is well noted to be a universal ailment that realization impaired bone mass and micro architectural deterioration thus enhancing the probability of fracture. Despite its high incidence, its management remains highly demanding because of the multifactorial pathophysiology of the disease. This review highlights recent findings in the management of osteoporosis particularly, gene expression and hormonal control.
