Children with medical complexity have a significant impact on health care cost and outcomes. Children with medical complexity are at risk for substantial polypharmacy and inherent drug-related dangers. In this special article, we describe the integration of clinical pharmacy services into our clinic for children with medical complexity. We review the process that yields results by effectively managing patients' medications across the continuum of care while also possibly improving health care spending and outcomes.As part of its core work, the WHO generates, translates and disseminates knowledge, including through guideline development. In recent years, substantial work has been undertaken to revise the Evidence to Decision framework in order to fully integrate inter alia human rights. This paper describes an innovative methodological approach taken by the authors to inform law and policy recommendations for the forthcoming third edition of the Safe Abortion Technical and Policy Guidance for Health Systems. The methodology described here effectively integrates human rights protection and enjoyment as part of health outcomes and analysis, ensuring that subsequent recommendations are consistent with international human rights standards. This will allow guideline users to make informed decisions on interventions, including legal and policy reform, to fulfil relevant human rights including the right to health.Gastric cancer cases are often diagnosed at an advanced stage with poor prognosis. Platinum-based chemotherapy has been internationally accepted as first-line therapy for inoperable or metastatic gastric cancer. To achieve greater benefits, selection of patients eligible for this treatment is critical. Although gene expression profiling has been widely used as a genomic classifier to identify molecular subtypes of gastric cancer and to stratify patients for different chemotherapy regimens, its prediction accuracy can be improved. Adenosine-to-inosine (A-to-I) RNA editing has emerged as a new player contributing to gastric cancer development and progression, offering potential clinical utility for diagnosis and treatment. Using a systematic computational approach followed by both in vitro validations and in silico validations in The Cancer Genome Atlas (TCGA), we conducted a transcriptome-wide RNA editing analysis of a cohort of 104 patients with advanced gastric cancer and identified an RNA editing (GCRE) signature to guide gastric cancer chemotherapy. RNA editing events stood as a prognostic and predictive biomarker in advanced gastric cancer. A GCRE score based on the GCRE signature consisted of 50 editing sites associated with 29 genes, predicting response to chemotherapy with a high accuracy (84%). selleck compound Of note, patients demonstrating higher editing levels of this panel of sites presented a better overall response. Consistently, gastric cancer cell lines with higher editing levels showed higher chemosensitivity. Applying the GCRE score on TCGA dataset confirmed that responders had significantly higher levels of editing in advanced gastric cancer. Overall, this newly defined GCRE signature reliably stratifies patients with advanced gastric cancer and predicts response from chemotherapy. SIGNIFICANCE This study describes a novel A-to-I RNA editing signature as a prognostic and predictive biomarker in advanced gastric cancer, providing a new tool to improve patient stratification and response to therapy.Renal cell carcinoma (RCC) is one of the most common urologic malignancies with the highest mortality rates worldwide. However, relevant mouse models that recapitulated the genetic alterations found in RCC have been lacking. In this study, we crossed Trp53 and Pten conditional knockout mice with Ggt1-Cre mice to generate a Ggt1-Cre; Trp53LoxP/LoxP ; PtenLoxP/LoxP ; YFPLoxP/LoxP (GPPY) mouse model, which resulted in the formation of dysplastic lesions involving kidney tubular epithelial cells (TEC), with only approximately 25% of mice developing RCC at an advanced age. Combining CRISPR/Cas9-mediated Vhl knockout in these mice increased the frequency of dysplasia, but failed to increase the incidence of RCC. Assessments of whether ischemic injury of TECs in the GPPY kidney without Vhl knockout influences the emergence of RCC revealed that advanced RCC predominantly emerged in the contralateral, noninjured kidney with 100% penetrance at a younger age, but rarely in the injured kidney due to severely damaged ischemic TEC. Injured TEC released CXCL1 into the microenvironment that traveled systemically to activate fibroblasts and recruit neutrophils to enable emergence of RCC in the contralateral kidney. Fibroblasts responded to CXCL1 via CXCR2 and recruited tumor-associated neutrophils, which in turn mediated tumor-promoting inflammation and angiogenesis. Treatment with anti-CXCR2 antibodies abolished the emergence of malignant RCC. Collectively, these results demonstrate a defining functional role of systemic inflammation and microenvironment in the emergence of malignant cancer from preestablished dysplastic precursor lesions. SIGNIFICANCE These results identify a role for CXCL1/CXCR2 and the tumor microenvironment in the development of RCC. GRAPHICAL ABSTRACT http//cancerres.aacrjournals.org/content/canres/81/10/2690/F1.large.jpg.See related commentary by Kusmartsev, p. 2584.Insights into oncogenesis derived from cancer susceptibility loci (SNP) hold the potential to facilitate better cancer management and treatment through precision oncology. However, therapeutic insights have thus far been limited by our current lack of understanding regarding both interactions of these loci with somatic cancer driver mutations and their influence on tumorigenesis. For example, although both germline and somatic genetic variation to the p53 tumor suppressor pathway are known to promote tumorigenesis, little is known about the extent to which such variants cooperate to alter pathway activity. Here we hypothesize that cancer risk-associated germline variants interact with somatic TP53 mutational status to modify cancer risk, progression, and response to therapy. Focusing on a cancer risk SNP (rs78378222) with a well-documented ability to directly influence p53 activity as well as integration of germline datasets relating to cancer susceptibility with tumor data capturing somatically-acquired genetic variation provided supportive evidence for this hypothesis.
