Introduction: The impact of young child formula (YCF) consumption on children's growth, particularly under suboptimal conditions, has scarcely been studied. In the current study, weight-for-age (WAZ), length-for-age (LAZ), and BMI-for-age (BAZ) z-score development was evaluated in children from five different countries (n = 668) who participated in a double-blind, randomized, controlled trial.

Methods: The children (1-3 years old) were randomized to one of two intervention YCFs (with presence or absence of prebiotics and n-3 LCPUFAs) during 52 weeks of intervention.

Background: Human milk comprises large fat globules enveloped by a native phospholipid membrane, whereas infant formulas contain small, protein-coated lipid droplets. Previous experimental studies indicated that mimicking the architecture of human milk lipid droplets in infant milk formula (IMF) alters lipid metabolism with lasting beneficial impact on later metabolic health.

Objectives: To evaluate in a follow-up (FU) study of a randomized, controlled trial whether a Concept IMF with large, milk phospholipid-coated lipid droplets enriched with dairy lipids beneficially impacts long-term body mass index (BMI in kg/m) trajectories and blood pressure at school age.

Background: Breastfeeding has been positively associated with infant and child neurocognitive development and function. Contributing to this effect may be differences between human milk and infant formula in the milk lipid composition and milk fat globule structure.

Objective: To evaluate the effects of an infant formula mimicking human milk lipid composition and milk fat globule structure on childhood cognitive performance.

Lipids are essential for healthy infant growth and development. The structural complexity of lipids in human milk is not present in infant milk formula (IF). A concept IF was developed mimicking more closely the structure and composition of human milk fat globules.

Objectives: The aim of the study was to assess the efficacy and tolerability of the monthly vaginal ring (NuvaRing; 15 μg ethinylestradiol [EE] and 120 μg etonogestrel per day) compared with a monophasic (21/7) combined oral contraceptive (COC) containing 30 μg EE and 3 mg drospirenone in healthy Chinese women aged 18-40 years.

Methods: This was a phase III, open-label, randomised multicentre trial conducted in China. Participants received NuvaRing or COC for 13 cycles (3 weeks of ring/pill treatment followed by a 1-week ring-free/pill-free period).

Background: The European CHOICE study was a cross-sectional survey that evaluated women's combined hormonal contraceptive choices before and after contraceptive counseling in Austria, Belgium, Czech Republic and Slovakia, the Netherlands, Poland, Sweden, Switzerland, Israel, Russia, and Ukraine. The changes in method selection before and after counseling were reported previously. In this paper we present the reasons given by the 18,787 participating women for selecting their contraceptive method of choice, as well as their perceptions about the contraceptive pill, patch, and ring after counseling.

Objective: To investigate the efficacy, safety, removal characteristics, and x-ray visibility of Nexplanon, a radiopaque etonogestrel contraceptive implant combined with a next-generation applicator.

Study Design: A 3-year, nocomparative, multicenter study in women aged 18-40 years at 23 clinical sites.

Results: Of 301 women who had an implant inserted, none became pregnant while the implant was in situ.

Objectives: To encourage healthcare professionals to counsel women seeking combined hormonal contraceptives (CHCs) about alternative CHCs and to study the influence of counselling on women's selection of CHCs.

Methods: Women (15-40 years old) in 11 countries who consulted HCPs about CHCs were counselled about the pill, transdermal patch, and vaginal ring. Both the HCPs and the women completed questionnaires.

Article Synopsis
  • Corifollitropin alfa is a single-injection treatment that replaces seven daily FSH injections in controlled ovarian stimulation (COS) cycles and was tested for safety and immunogenicity.
  • A study involved 682 patients starting their first cycle, with no significant immune reactions or hypersensitivity to the drug reported, and side effects included procedural pain, headaches, and pelvic discomfort.
  • After three cycles, the cumulative pregnancy rate was 61%, indicating that corifollitropin alfa is a safe and effective option for ovarian stimulation without immunogenicity concerns.

Objectives: To evaluate the tolerability and clinical safety of the subdermal, long-acting hormonal contraceptive Implanon.

Methods: This integrated safety analysis included 11 international studies concerning Implanon (68 mg etonogestrel) of which 10 had a duration of at least two years. Assessments included reports of adverse events (AEs), reasons and rates of discontinuation, insertion/removal complications, and the condition of the implant site.

Objectives: To evaluate an integrated analysis of bleeding patterns associated with use of the subdermal contraceptive implant Implanon (etonogestrel, Organon, part of Schering-Plough) and to provide physician guidance to optimize patient counselling.

Methods: Data from 11 clinical trials were reviewed (N = 923). Assessments included bleeding-spotting records, dysmenorrhoea, and patient-perceived reasons for discontinuation.
