En el análisis multivariable para la OS, se incluyeron los tumores del colon derecho, las metástasis linfáticas primarias y la metástasis hepática bilobar; un TTV ≥ 100 mL se asoció de forma independiente con una peor OS (cociente de riesgos instantáneos, hazard ratio, HR, 6,34, i.c. del 95% 2,08-17,9; P = 0,002). En el anáisis para la RFS, se incluyeron tumores primarios de colon derecho y las metástasis linfáticas primarias; un TTV ≥ 10 mL predijo de forma independiente una peor RFS (HR 1,90, i.c. del 95% 1,12-3,57; P = 0,017). Las tasas de OS a los 5 años con TTVs ≥ 100 mL versus less then  100 mL fueron del 41% versus 67% (P = 0,006); las tasas de RFS respecto a TTVs ≥ 10 mL versus less then  10 mL fueron del 14% versus 58% (P = 0,009). Un TTV ≥ 100 mL conllevó una tasa más elevada (80%) de recidivas no resecables después de la HR inicial. CONCLUSIÓN El TTV se asoció con la RFS y la OS tras la HR por CRLMs; unos valores ≥ 100 mL conllevan una tasa más elevada de recidiva irresecable.BACKGROUND Little is known about how to facilitate participation in physical activity among children receiving acute cancer treatment. OBJECTIVE To understand the parental perspectives on physical activity for children during acute cancer treatment and explore strategies to overcome physical inactivity. METHODS A qualitative study was completed. Data were collected via semistructured interviews with parents of children (aged 4-18 years) who were in their first nine months of cancer treatment. Data were analyzed thematically. RESULTS Twenty parents were interviewed. A childhood cancer diagnosis and subsequent treatment were described as setting in motion a spiral of physical inactivity. Parents identified movement restrictions as a result of commencing treatment and the hospital environment as factors initiating this decline. Parents described the subsequent impact of movement restrictions on their child over time including loss of independence, isolation, and low motivation. These three consequences further contributed to an inability and unwillingness to be physically active. Parents responded in a variety of ways to their child's inactivity, and many were motivated to overcome the barriers to physical activity yet exhibited a reduced capacity to do so. Suggested intervention strategies highlighted the need for comprehensive support from the organization providing treatment. CONCLUSIONS Reasons for reduced physical activity in children receiving acute treatment for cancer are complex and multifactorial. Inactivity cannot be addressed by children and parents alone but requires support from the oncology team through changes to the environment, services, and policies to promote physical activity. These findings may be used to inform targeted, effective, and feasible physical activity interventions. © 2020 Wiley Periodicals, Inc.In the present study, we examined administrative data on 667,437 deployments of at least 30 days duration to Iraq and Afghanistan from 2011 through the end of 2016 to determine risk factors for evacuation from the combat zone for behavioral health reasons. Demographic data, military-specific data, responses on predeployment mental health assessments, and presence of previous treatment for psychiatric conditions were entered into a logistic regression based on expert determination, distinguishing the 2,133 behavioral health evacuations from those deployments that either did not end in evacuation or included evacuations for reasons other than behavioral health. The model, derived from a random half of the sample (training set), was verified on the other half (validation set). Predictor variables used in the model were calendar year; gender; age; rank; marital status; parental status; number of prior war zone deployments; branch of service; screens for symptoms of posttraumatic stress disorder, depression, and hazardous alcohol use on the predeployment mental health assessment; and prior substance- and non-substance-related behavioral health diagnoses. Odds ratios (range 1.05-3.85) for selected variables that contributed to the model were used to assign risk scores in the Behavioral Health Evacuation Risk Tool, which can aid predicting which service members are more likely to be evacuated from combat for behavioral health reasons, thus indicating where resources can be allocated for behavioral health referrals and war zone care. © 2020 International Society for Traumatic Stress Studies.We report model experiments in which simple microinjection of fertilized eggs has been used to effectively perform homology-directed repair (HDR)-mediated gene editing in the two Xenopus species used most frequently for research X. tropicalis and X. laevis.  https://www.selleckchem.com/products/trastuzumab-emtansine-t-dm1-.html  We have used long single-stranded DNAs having phosphorothioate modifications as donor templates for HDR at targeted genomic sites using the Clustered Regularly Interspaced Short Palindromic Repeats/CRISPR-associated protein 9 (CRISPR/Cas9) system. First, X. tropicalis tyr mutant (i.e., albino) embryos were successfully rescued partially pigmented tadpoles were seen in up to 35% of injected embryos, demonstrating the potential for efficient insertion of targeted point mutations. Second, in order to demonstrate the ability to tag genes with fluorescent proteins (FPs), we targeted the melanocyte-specific gene slc45a2.L of X. laevis to label it with the Superfolder green FP (sfGFP), seeing mosaic expression of sfGFP in melanophores in up to 20% of injected tadpoles. Tadpoles generated by these two approaches were raised to sexual maturity, and shown to successfully transmit HDR constructs through the germline with precise targeting and seamless recombination. F1 embryos showed rescue of the tyr mutation (X. tropicalis) and tagging in the appropriate pigment cell-specific manner of slc45a2.L with sfGFP (X. laevis). © 2020 Wiley Periodicals, Inc.Burnout is a significant problem in the medical community, including among pediatric hematology/oncology (PHO) faculty. However, the prevalence of burnout, its associated risk factors, and outcomes within PHO fellows are unknown. We present the results of a cross-sectional study of PHO fellows from 21 training programs. A total of 45/115 fellows (39.1%) met criteria for high level of burnout. Fellows who met criteria for high burnout also demonstrated poor outcomes including decreased empowerment, increased doctor-centered care, decreased self-assessed humanism, and decreased satisfaction with training. Further longitudinal investigation is needed to better understand burnout and the causative factors affecting PHO fellows. © 2020 Wiley Periodicals, Inc.
