Introduction This paper provides the results of a year-long evaluation of a large-scale integrated care pilot in north-west London. The pilot aimed to integrate care across primary, acute, community, mental health and social care for people with diabetes and/or those aged 75+ through care planning, multidisciplinary case reviews, information sharing and project management support. Methods The evaluation team conducted qualitative studies of change at organisational, clinician and patient levels (using interviews, focus groups and a survey); and quantitative analysis of change in service use and patient-level clinical outcomes (using patient-level datasets and a matched control study). Results The pilot had successfully engaged provider organisations, created a shared strategic vision and established governance structures. However, the engagement of clinicians was variable and there was no evidence to date of significant reductions in emergency admissions. There was some evidence of changes in care processes. Conclusion Although the pilot has demonstrated the beginnings of large-scale change, it remains in the early stages and faces significant challenges as it seeks to become sustainable for the longer term. It is critical that National Health Service managers and clinicians have realistic expectations of what can be achieved in a relatively short period of time.
Extracellular matrix adhesion is required for normal epithelial cell survival, nutrient uptake and metabolism. This requirement can be overcome by oncogene activation. Interestingly, inhibition of PI3K/mTOR leads to apoptosis of matrix-detached, but not matrix-attached cancer cells, suggesting that matrix-attached cells use alternate mechanisms to maintain nutrient supplies. Here we demonstrate that under conditions of dietary restriction or growth factor starvation, where PI3K/mTOR signalling is decreased, matrix-attached human mammary epithelial cells upregulate and internalize β4-integrin along with its matrix substrate, laminin. Endocytosed laminin localizes to lysosomes, results in increased intracellular levels of essential amino acids and enhanced mTORC1 signalling, preventing cell death. Moreover, we show that starved human fibroblasts secrete matrix proteins that maintain the growth of starved mammary epithelial cells contingent upon epithelial cell β4-integrin expression. Our study identifies a crosstalk between stromal fibroblasts and epithelial cells under starvation that could be exploited therapeutically to target tumours resistant to PI3K/mTOR inhibition.
Purpose The purpose of this pilot study was to assess the feasibility and effectiveness of an intense health promotion program in older adults with diabetes. The program combined individually prescribed and supervised exercise with nutrition and education programs on glycemic control and aerobic fitness. Methods Various recruitment and retention strategies were analyzed for effectiveness. Out of 28 potential subjects assessed for eligibility, 6 subjects with type 2 diabetes (2 male and 4 female; all white; age, 60.2 ± 4.7 years) participated in the 10-week intervention. Aerobic and resistance exercise was performed on alternate days (3-4 days per week), with individualized nutrition counseling and diabetes health education sessions once weekly. The primary outcome measures were aerobic fitness and glycemic control (A1C), and secondary outcome measures included body mass index (BMI), self-efficacy, and symptoms of neuropathy. Changes in outcomes were assessed using descriptive statistics and paired t test analysis (α = .05). Results Following the intervention, subjects had improvements that approached significance in A1C and pain, with significant improvements in self-efficacy. Conclusions A systematic approach to analysis of feasibility revealed issues with recruitment and retention that would need to be addressed for future studies or clinical implementation of this program. However, for the subset of subjects who did complete the intervention, adherence was excellent, and satisfaction with the program was confirmed by exit interview comments. Following participation in this pilot health promotion program, subjects had meaningful improvements in glycemic control, pain, and self-efficacy.
Patients who were older, black, or had uterine and cervical cancers were more likely to use PC. Although the overall use of PC has increased, less than one-quarter of patients who died in the hospital used PC services during their final hospital admission.
