Continuous Support from the Same Public Health Nurse and Parental Perception and Use of Health Care Services: A Retrospective Observational Study.

Objective: Continuity is considered essential for high-quality maternal and child health care services, but studies to show this effect on parental well-being are still rare. We studied whether receiving support from the same public health nurse has a beneficial effect on parental perceptions of health care professionals and the use of childcare support services.

Methods: Maternal and child health care services were provided by different nurses in a Japanese municipality until March 2019.

Cytoplasmic dysmorphisms in metaphase II chimpanzee oocytes.

Prior to fertilization by intracytoplasmic sperm injection (ICSI), cytoplasmic organization was evaluated in metaphase II chimpanzee oocytes obtained from stimulated ovaries. The findings demonstrate a high frequency of anomalies that are remarkably similar to the types of cytoplasmic dysmorphisms reported for human oocytes used in IVF. Similar to the human, the occurrence of these anomalies was oocyte- and animal-specific and associated with reduced competence as indicated by embryo development in vitro to the blastocyst stage.
