The NCS code of practice for the quality assurance of treatment planning systems (NCS-35).

A subcommittee of the Netherlands Commission on Radiation Dosimetry (NCS) was initiated in 2018 with the task to update and extend a previous publication (NCS-15) on the quality assurance of treatment planning systems (TPS) (Bruinvis2005). The field of treatment planning has changed considerably since 2005. Whereas the focus of the previous report was more on the technical aspects of the TPS, the scope of this report is broader with a focus on a department wide implementation of the TPS.

Nurses' knowledge and attitudes regarding children's pain assessment and management in Nepal.

Pain is frequently experienced by children in hospital, and international guidelines for appropriate pain assessment and management are available. Optimal management of paediatric pain has important long-term health, psychosocial, and economic benefits. However, evidence indicates that globally there are deficits in nurses' understanding of paediatric pain assessment and management.

Meeting Maternal and Reproductive Health Needs in a Post-Disaster Setting: A Qualitative Case Study From Indonesia.

Meeting and planning for maternal and reproductive health (MRH) needs during post-disaster scenarios is paramount, however, not without considerable challenges. This study was aimed at understanding the provision of MRH services in Siosar, a relocation site for a population displaced by the volcanic eruption in 2013 of Mount Sinabung, Indonesia. A qualitative case study approach was used, and data were collected through focus group discussions and individual interviews with women of reproductive age, community leaders, health personnel, and policymakers.

Historical Aspects of Gene Therapy and Stem Cell Therapy in the Treatment of Hearing and Balance Disorder.

This review presents many but not all the major historical events that have led to our current understanding of gene and stem cell therapies for the treatment of hearing and balance disorders in animal models of these disorders. In order to better understand the application of these emerging therapies to the treatment of inner ear disorders in a clinical setting, it has been necessary to provide some genetic and pathobiology backgrounds from both animal models and clinical disorders. The current focus and goal of gene and stem cell therapies are directed toward understanding the effective treatment of animal models that mimic human disorders of hearing and balance.

Isolation and Characterization of Mammalian Otic Progenitor Cells that Can Differentiate into Both Sensory Epithelial and Neuronal Cell Lineages.

The mammalian inner ear mediates hearing and balance and during development generates both cochleo-vestibular ganglion neurons and sensory epithelial receptor cells, that is, hair cells and support cells. Cell marking experiments have shown that both hair cells and support cells can originate from a common progenitor. Here, we demonstrate the lineage potential of individual otic epithelial cell clones using three cell lines established by a combination of limiting dilution and gene-marking techniques from an embryonic day 12 (E12) rat otocyst.
