Image-based force inference by biomechanical simulation.

During morphogenesis, cells precisely generate forces that drive cell shape changes and cellular motion. These forces predominantly arise from contractility of the actomyosin cortex, allowing for cortical tension, protrusion formation, and cell division. Image-based force inference can derive such forces from microscopy images, without complicated and time-consuming experimental set-ups.

Outcomes of female fertility preservation with cryopreservation of oocytes or embryos in the Netherlands: a population-based study.

Study Question: What are the reproductive outcomes of patients who cryopreserved oocytes or embryos in the context of fertility preservation in the Netherlands?

Summary Answer: This study shows that after a 10-year follow-up period, the utilization rate to attempt pregnancy using cryopreserved oocytes or embryos was 25.5% and the cumulative live birth rate after embryo transfer was 34.6% per patient.

Value-based healthcare in fertility care using relevant outcome measures for the full cycle of care leading towards shared decision-making: a retrospective cohort study.

Objective: To determine if the introduction of value-based healthcare (VBHC) in fertility care can help to create realistic expectations in patients resulting in increased patient value, by demonstrating the relevance of defining outcome measures that truly matter to subfertile patients.

Design: Retrospective cohort study.

Setting: Tertiary fertility centre.

A multicentre double-blinded randomized controlled trial on the efficacy of laser-assisted hatching in patients with repeated implantation failure undergoing IVF or ICSI.

Study Question: Does assisted hatching increase the cumulative live birth rate in subfertile couples with repeated implantation failure?

Summary Answer: This study showed no evidence of effect for assisted hatching as an add-on in subfertile couples with repeated implantation failure.

What Is Known Already: The efficacy of assisted hatching, with regard to the live birth rate has not been convincingly demonstrated in randomized trials nor meta-analyses. It is suggested though that especially poor prognosis women, e.

Cell shape characterization, alignment, and comparison using FlowShape.

Motivation: The shape of a cell is tightly controlled, and reflects important processes including actomyosin activity, adhesion properties, cell differentiation, and polarization. Hence, it is informative to link cell shape to genetic and other perturbations. However, most currently used cell shape descriptors capture only simple geometric features such as volume and sphericity.
