Safety and immunogenicity of an investigational quadrivalent meningococcal tetanus toxoid conjugate vaccine (MenACYW-TT) co-administered with routine pediatric vaccines in infants and toddlers: A Phase II study.

Background: The MenACYW-TT conjugate vaccine is approved for prevention of invasive meningococcal disease (IMD) as a single dose in individuals ≥2 years of age in the United States and ≥12 months in EU and some other countries. This Phase II study evaluated the safety and immunogenicity of this vaccine and of concomitant pediatric vaccines in infants/toddlers (6 weeks-15 months of age).

Methods: Five schedules of the MenACYW-TT conjugate vaccine were evaluated in the United States: 2, 4, 6, and 12 months; 2, 4, 6, and 15 months; 2, 4, and 12 months; 6 and 12 months; and 12 months alone.

Real-World Anticoagulant Use and Incidence of Venous Thromboembolism and Major Bleeding in Children.

Purpose: Children generally have a lower risk of venous thromboembolism (VTE) than adults, but those with acute and chronic conditions requiring hospitalization and surgical procedures are at increased risk. Anticoagulant use in children has not been systematically studied, and limited data exist. This study aimed to provide data on the conditions associated with use of anticoagulants, the type of anticoagulant used in children, and the incidence of thromboembolism and major bleeding events reported in this population.

Thromboprophylaxis for Children Post-Fontan Procedure: Insights From the UNIVERSE Study.

Background Patients with single-ventricle physiology who undergo the Fontan procedure are at risk for thrombotic events associated with significant morbidity and mortality. The UNIVERSE Study evaluated the efficacy and safety of a novel liquid rivaroxaban formulation, using a body weight-adjusted dosing regimen, versus acetylsalicylic acid (ASA) in children post-Fontan. Methods and Results The UNIVERSE Study was a randomized, multicenter, 2-part, open-label study of rivaroxaban, in children who had undergone a Fontan procedure, to evaluate its dosing regimen, safety, and efficacy.

Immunogenicity and safety of a quadrivalent meningococcal tetanus toxoid-conjugate vaccine (MenACYW-TT) in adults 56 years of age and older: a Phase II randomized study.

MenACYW-TT is an investigational quadrivalent meningococcal conjugate vaccine intended for the prevention of invasive meningococcal disease (IMD) caused by serogroups A, C, W, and Y in individuals aged 6 weeks and above. This Phase II, randomized, open-label, multicenter, exploratory study assessed the safety and immunogenicity of MenACYW-TT compared with a quadrivalent meningococcal polysaccharide vaccine (MPSV4) in 301 healthy adults aged ≥56 y in the US (NCT01732627). Participants were randomized 2:1 to receive MenACYW-TT or MPSV4.

Isotope analyses to explore diet and mobility in a medieval Muslim population at Tauste (NE Spain).

The Islamic necropolis discovered in Tauste (Zaragoza, Spain) is the only evidence that a large Muslim community lived in the area between the 8th and 10th centuries. A multi-isotope approach has been used to investigate the mobility and diet of this medieval Muslim population living in a shifting frontier region. Thirty-one individuals were analyzed to determine δ15N, δ13C, δ18O and 87Sr/86Sr composition.

[Intentional search and reclassification of maternal deaths in Mexico: The effect on the distribution of causes].

Objective: To correct the misclassification and improve the quality of information on maternal mortality in Mexico.

Materials And Methods: Using clinical records and verbal autopsies, we studied all deaths certified as maternal deaths as well as a selection of deaths of women of childbearing age whose causes were considered as suspected of hiding a maternal death, all of which occurred during 2011 within Mexico.

Results: The deliberate search of maternal deaths and reclassification allowed the rescue of just over 100 deaths that were not originally registered or coded as maternal and confirmed or corrected the causes of death recorded on death certificates as confirmed maternal deaths.

Safety and immunogenicity of a quadrivalent meningococcal polysaccharide diphtheria toxoid conjugate vaccine in infants and toddlers: three multicenter phase III studies.

Background: Quadrivalent meningococcal conjugate vaccine (Menactra [MenACWY-D]), was licensed in the United States in 2005 to prevent meningococcal disease in adolescents and adults. The license was extended to children aged 2-10 years in 2007 and extended again in 2011 to infants aged 9 months and older based, in part, on results from 3 phase III studies presented herein.

Methods: The safety and immunogenicity of 2 doses of MenACWY-D was assessed in study-eligible children: dose 1 was administered at 9 months of age and dose 2 was administered 3 months later with or without routine childhood vaccines.

Safety and immunogenicity of a meningococcal (Groups A, C, Y, W-135) polysaccharide diphtheria toxoid conjugate vaccine in healthy children aged 2 to 10 years in Chile.

Immune responses to meningococcal conjugate (Menactra; MCV-4) and plain polysaccharide (Menomune-A/C/Y/W-135; PSV-4) vaccines against serogroups A, C, Y, and W-135 were assessed in 220 of 1037 Chilean children aged 2 to 10 years participating in a comparative safety trial. Both vaccines were generally well tolerated. Geometric mean serum bactericidal antibody (SBA) titers 28 days postvaccination were comparable in both groups for all four serogroups.
