The metastatic behavior of the HT-29 human colorectal carcinoma cell line was studied following injection into nude mice by different routes. After intrasplenic injection, experimental metastases formed in the livers of most mice. Variant lines were established in culture from the liver lesions and from tumors growing at the site of injection, the spleen. Cells of the HT-29 LMM line exhibited slightly enhanced ability to form liver metastases compared with cells of the non-selected parent line. When injected i.v., the HT-29 cells produced only a few small experimental metastases in the lungs, but in most of the mice macroscopic tumors were found in various lymph nodes and the interscapular fat. Analyses of the distribution of IdUrd-labeled cells did not reveal a preferential localization of the HT-29 cells in sites where metastases subsequently formed. This suggested that the growth of the human colon carcinoma cells in those sites might be the result of a stimulatory interaction between the tumor and host cells as opposed to growth in sites such as the lungs, where numerous cells arrested after i.v. injection but only a few, small metastases were seen 60 days later.

Collaboration between EM and GM physicians around patients in the gray zone, focusing on patient risk, cost, and outpatient resources, may provide an avenues for reducing potentially preventable admissions and lowering healthcare spending.

ObjectiveTo improve quality of life (QOL) in patients at risk for post–intensive care syndrome (PICS).Patients and MethodsWe conducted a mixed-method, prospective, observational, pre-post interventional study in an adult medical and mixed medical/surgical/transplant intensive care unit (ICU) at a tertiary academic hospital. Preintervention included patients admitted from October 1 through October 31, 2016, and postintervention included patients admitted from January 15 through February 14, 2017. First, a multidisciplinary team of stakeholders identified barriers associated with decreased QOL in patients at risk for PICS. Next, interventions were designed and implemented. The effect of interventions was assessed using a mixed-method analysis. The qualitative analysis used a modified grounded theory approach. The quantitative analysis included assessment of preexisting symptoms and risk factors associated with PICS. The 36-Item Short-Form Health Status Survey (SF-36), which surveys physical and mental composite scores, was used to assess QOL.ResultsBarriers identified were lack of awareness and understanding of PICS. Interventions included educational videos, paper and online education and treatment materials, and online and in-person support groups for education and treatment. After interventions, the qualitative analysis found that patients who participated in the interventions after hospital discharge showed improved QOL, whereas education during hospitalization alone was not effective. The quantitative analysis did not find improvement in QOL, as defined by SF-36 physical or mental composite scores.ConclusionInterventions targeted to patients after hospitalization may offer subjective improvement in QOL for those at risk for PICS.

Objective Healthy lifestyle interventions addressing obesity in people with serious mental illness (SMI) lead to modest weight losses that tend not to be sustained over time. By augmenting lifestyle interventions with family and peer support targeting health behavior change, greater weight loss might be obtained and sustained in this population. The purpose of this study was to assess the feasibility of increasing support from family and friends to enhance a healthy lifestyle intervention (In SHAPE) adapted for individuals with SMI. Method A sample of 7 dyads (14 total participants) participated in this small-scale open-feasibility trial of social support strategies to enhance health promotion. Weekly 1-hour health coaching sessions were augmented by sessions designed to increase support for healthy eating and exercise through active learning and didactic instruction. Feasibility was assessed by program participation and by examining participants’ satisfaction and exploring suggestions for improving the model post-intervention. Results The majority of participants (57%) nominated a friend, followed by adult child-parent pairs (28%) and sibling pairs (14%) to participate as support partners in the study. All participant-partner dyads (100%) completed 12 sessions within 16 weeks. Participants reported high satisfaction and perceived benefits from the program. Recommend modifications by the dyads included more interactive sessions, a combination of group and dyadic sessions, and hands-on cooking classes. Conclusions This formative research showed that the study design is feasible and that the intervention can facilitate social support for health behavior change in people with SMI. Further research is needed to evaluate the effectiveness of this intervention.
