Education Following Pediatric Gastrostomy Tube Placement: An Integrative Review.

BACKGROUND: There is a gap in knowledge regarding the necessary components for pediatric gastrostomy tube education. This integrative review addresses the question "What are the educational components following pediatric gastrostomy placement?" METHODS: A literature search was conducted using PubMed, CINAHL, and Cochrane Library electronic databases, along with a hand search. Articles for review included those in the pediatric population, English language, and publication dates between 2010 and 2020. RESULTS: Ultimately, 7 articles met the inclusion criteria for review. Articles were all pediatric focused (0-18 years), and were a mix of quantitative and qualitative designs, along with one non-research paper. Three major themes were identified from the literature including that gastrostomy tube education should be a multidisciplinary effort, that education should take a standardized approach, and that it should include psychosocial elements that enhance caregiver knowledge and empowerment. DISCUSSION: This review demonstrates that while there is no consensus on a superior mode or means of education, pediatric gastrostomy discharge education must be standardized and high quality to promote the best patient and caregiver outcomes. Further research should aim to address which forms of education, if any, lead to the best outcomes, and how education can best be delivered to promote caregiver knowledge and ease.

Very High-Risk Localized Prostate Cancer: Outcomes Following Definitive Radiation.

PURPOSE: Existing definitions of high-risk prostate cancer consist of men who experience significant heterogeneity in outcomes. As such, criteria that identify a subpopulation of National Comprehensive Cancer Network (NCCN) high-risk prostate cancer patients who are at very high risk (VHR) for poor survival outcomes following prostatectomy were recently developed at our institution and include the presence of any of the following disease characteristics: multiple NCCN high-risk factors, primary Gleason pattern 5 disease and/or ≥5 biopsy cores with Gleason sums of 8 to 10. Whether these criteria also apply to men undergoing definitive radiation is unclear, as is the optimal treatment regimen in these patients. METHODS AND MATERIALS: All men consecutively treated with definitive radiation by a single provider from 1993 to 2006 and who fulfilled criteria for NCCN high-risk disease were identified (n=288), including 99 patients (34%) with VHR disease. Multivariate-adjusted competing risk regression models were constructed to assess associations between the VHR definition and biochemical failure (BF), distant metastasis (DM), and prostate cancer-specific mortality (PCSM). Multivariate-adjusted Cox regression analysis assessed the association of the VHR definition with overall mortality (OM). Cumulative incidences of failure endpoints were compared between VHR men and other NCCN high-risk men. RESULTS: Men with VHR disease compared to other NCCN high-risk men experienced a higher 10-year incidence of BF (54.0% vs 35.4%, respectively, P<.001), DM (34.9% vs 13.4%, respectively, P<.001), PCSM (18.5% vs 5.9%, respectively, P<.001), and OM (36.4% vs 27.0%, respectively, P=.04). VHR men with a detectable prostate-specific antigen (PSA) concentration at the end of radiation (EOR) remained at high risk of 10-year PCSM compared to VHR men with an undetectable EOR PSA (31.0% vs 13.7%, respectively, P=.05). CONCLUSIONS: NCCN high-risk prostate cancer patients who meet VHR criteria experience distinctly worse outcomes following definitive radiation and long-term androgen deprivation therapy, particularly if an EOR PSA is detectable. Optimal use of local therapies for VHR patients should be explored further, as should novel agents.

Genetic factors in drug metabolism.

Patients vary widely in their response to drugs. Having an understanding of the pharmacokinetic and pharmacodynamic properties of various medications is importantwhen assessing ethnic differences in drug response. Genetic factors can account for 20 to 95 percent of patient variability. Genetic polymorphisms for many drug-metabolizing enzymes and drug targets (e.g., receptors) have been identified. Although currently limited to a few pathways, pharmacogenetic testing may enable physicians to understand why patients react differently to various drugs and to make better decisions about therapy. Ultimately, this understanding may shift the medical paradigm to highly individualized therapeutic regimens.
