A Phase 3 Open-label, Randomized, Controlled Study to Evaluate the Efficacy and Safety of Intravenously Administered Ravulizumab Compared with Best Supportive Care in Patients with COVID-19 Severe Pneumonia, Acute Lung Injury, or Acute Respiratory Distress Syndrome: A structured summary of a study protocol for a randomised controlled trial.

Objectives: Primary Objective • To evaluate the effect of ravulizumab, a long-acting complement (C5) inhibitor plus best supportive care (BSC) compared with BSC alone on the survival of patients with COVID-19. Secondary Objectives • Number of days free of mechanical ventilation at Day 29 • Duration of intensive care unit stay at Day 29 • Change from baseline in Sequential Organ Failure Assessment (SOFA) score at Day 29 • Change from baseline in peripheral capillary oxygen saturation/ fraction of inspired oxygen (SpO2 /FiO2) at Day 29 • Duration of hospitalization at Day 29 • Survival (based on all-cause mortality) at Day 60 and Day 90 Safety • Incidence of treatment-emergent adverse events and treatment-emergent serious adverse events. PK/PD/Immunogenicity • Change in serum ravulizumab concentrations over time • Change in serum free and total C5 concentrations over time • Incidence and titer of anti-ALXN1210 antibodies Biomarkers • Change in absolute level of soluble biomarkers in blood associated with complement activation, inflammatory processes, and hypercoagulable states over time Exploratory • Incidence of progression to renal failure requiring dialysis at Day 29 • Time to clinical improvement (based on a modified 6-point ordinal scale) over 29 days • SF-12 Physical Component Summary (PCS) and Mental Component Summary (MCS) scores at Day 29 (or discharge), Day 60, and Day 90 • EuroQol 5-dimension 5-level (EQ-5D-5L) scores at Day 29 (or discharge), Day 60, and Day 90 TRIAL DESIGN: This is a multicenter Phase 3, open-label, randomized, controlled, study.

Lack of Serum anti-Mullerian hormone responses after recombinant human chorionic gonadotropin stimulation in women with polycystic ovary syndrome.

Context: Polycystic ovary syndrome (PCOS) is an anovulatory disorder characterized by excess androgen production and increased LH secretion. Serum anti-Mullerian hormone (AMH) is also elevated in this disorder. Women with PCOS exhibit a positive correlation between AMH and LH levels and recent in vitro data demonstrate that LH can directly stimulate AMH production by granulosa cells from women with PCOS.

Markers of muscle ischemia, necrosis, and inflammation following uterine artery embolization in the treatment of symptomatic uterine fibroids.

Objective: The objective of the study was to quantify markers of myometrial ischemia, necrosis, and inflammation in women undergoing uterine artery embolization (UAE).

Study Design: Women with symptomatic fibroids were randomized to treatment with UAE (n = 14) or abdominal myomectomy (n = 11). Peripheral venous blood samples were taken before and after the procedure, at 24 hours and 6 weeks.

Interleukin-8 levels in seminal plasma in chronic prostatitis/chronic pelvic pain syndrome and nonspecific urethritis.

Objective: To investigate whether a range of cytokines were detectable in the seminal plasma and urine of men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and nonspecific urethritis (NSU), and whether cytokine levels correlated with symptom severity in CP/CPPS.

Patients And Methods: In all, 87 men participated, 33 with CP/CPPS, 31 with NSU, and 23 controls. Interleukin (IL)-1beta, IL-2, IL-6, IL-8 and IL-10 were measured in seminal plasma and first pass urine, and the results were correlated with scores for pain, urinary symptoms and quality-of-life impact using a validated symptom index, the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI).

Breast cancer genetics: unsolved questions and open perspectives in an expanding clinical practice.

Breast cancer is the most common cause of cancer death in the United Kingdom, with a lifetime risk of one in nine in women. Only 5-10% of all cancers is thought to be due to strongly penetrant inherited predisposing genes, such as BRCA1 and BRCA2. However, other less penetrant genes, including some autosomal recessive genes, are likely to be of etiological importance in other families.
