Cancer survivors' perspectives of dietary information provision after cancer treatment: A scoping review of the Australian context.

Issue Addressed: To support survivor-centred care in Australia, this review maps current knowledge regarding adult cancer survivors' perspectives of dietary information provision post-treatment.

Methods: A scoping review of research conducted in Australia within the past decade reported using PRISMA-ScR guidelines. Seven databases were searched (01/01/2009-05/06/2020) and records were independently screened by two researchers using eligibility criteria.

Reproducibility and staging of 3D human retinal organoids across multiple pluripotent stem cell lines.

Numerous protocols have been described for producing neural retina from human pluripotent stem cells (hPSCs), many of which are based on the culture of 3D organoids. Although nearly all such methods yield at least partial segments of retinal structure with a mature appearance, variabilities exist within and between organoids that can change over a protracted time course of differentiation. Adding to this complexity are potential differences in the composition and configuration of retinal organoids when viewed across multiple differentiations and hPSC lines.

3D Microstructured Scaffolds to Support Photoreceptor Polarization and Maturation.

Blinding disorders of the outer retina involve dysfunction and degeneration of photoreceptors. One potential approach to treat these forms of blindness is to repopulate the outer retina via a simple bolus injection of donor photoreceptors. However, this may not be ideal due to the highly polarized organization of photoreceptors that include apical light sensing photopigments and basal axon terminals.

Generation of a rod-specific NRL reporter line in human pluripotent stem cells.

Reporter lines generated in human pluripotent stem cells can be highly useful for the analysis of specific cell types and lineages in live cultures. We created the first human rod reporter line using CRISPR/Cas9 genome editing to replace one allele of the Neural Retina Leucine zipper (NRL) gene with an eGFP transgene in the WA09 human embryonic stem cell (hESC) line. After confirming successful targeting, three-dimensional optic vesicle structures were produced to examine reporter specificity and to track rod differentiation in culture.

A Novel Approach to Single Cell RNA-Sequence Analysis Facilitates In Silico Gene Reporting of Human Pluripotent Stem Cell-Derived Retinal Cell Types.

Cell type-specific investigations commonly use gene reporters or single-cell analytical techniques. However, reporter line development is arduous and generally limited to a single gene of interest, while single-cell RNA (scRNA)-sequencing (seq) frequently yields equivocal results that preclude definitive cell identification. To examine gene expression profiles of multiple retinal cell types derived from human pluripotent stem cells (hPSCs), we performed scRNA-seq on optic vesicle (OV)-like structures cultured under cGMP-compatible conditions.

Best practices in the pediatric pretransplant psychosocial evaluation.

Assessment of psychosocial functioning is an often-included component of the pretransplant evaluation process. This study reviews several domains of assessment that have been related to post-transplant outcomes across solid organ transplant populations. These include evaluation of patient and family past adherence, knowledge about the transplantation process, and their neurocognitive, psychological, and family functioning.

Predictors of parent-child interaction style in dyads with autism.

Parent synchrony has been shown to be developmentally important for the growth of communication skills in young children with autism. Understanding individual-differences in parent synchrony and other associated features of dyadic interaction therefore presents as an important step toward the goal of appreciating how and why some parent-child dyads come to adopt more optimal interaction styles, while for others, parent interaction is more asynchronous and less developmentally facilitative. Within the large, well-characterized Preschool Autism Communication Trial (PACT) cohort, baseline parent-child interaction samples were coded for three key aspects of dyadic interaction style; - Parent Synchrony, Child Initiation, and Shared Attention.
