Evaluation of the impact on hospitalization risk of an electronic pill-box to promote therapeutic adherence in post-acute care setting: a pilot study.

Literature review reveals that adherence to prescribed therapy at hospital discharge averages around 50%. The purpose of this study was to evaluate adherence to prescribed therapy assessing the relationship between re-hospitalization rate at 30 days and degree of therapeutic adherence in a sample of elderly patients discharged from an acute geriatric ward using an Electronic Medication Packaging device, MePill. The study population (n = 56) was divided in 3 groups, a counseling group (A), a counseling + MePill device group (B) and a control group (C). Group A had 98.1% adherence to therapy, Group B had 100%, and control group had 90%. Analyzing the rate of hospitalization by type of intervention for Group A and C the hospitalization rate was 21% and 27.7%, respectively, whilst for Group B no patient was hospitalized. Participants in Group A and C had the shorter hospitalization-free survival as compared with subjects in Group B.

Morphological and Functional Changes in the Peritumoral Adipose Tissue of Colorectal Cancer Patients.

OBJECTIVE: The role of peritumoral adipose tissue (AT) has not been extensively studied in colorectal cancer (CRC). METHODS: This study was conducted in 20 male subjects undergoing elective surgery for CRC. The differences between the peritumoral visceral adipose tissue (P-VAT), visceral adipose tissue (VAT), and subcutaneous adipose tissue (SAT) of the patients were described via immunohistochemistry and molecular biology analyses. The interactions between adipocytes and a colon cancer cell line were also investigated by using an in vitro coculture system. RESULTS: The analyses revealed that adipocytes near the tumor were significantly smaller than the adipocytes from other sites. The P-VAT was preferentially infiltrated by a CD68+/CD163+/IDO- macrophage subset with a prevalent reparative inflammatory response, while the macrophages identified in VAT and SAT mainly presented inflammatory features. Furthermore, the P-VAT presented a higher expression of adiponectin compared with other sites. Morphological analysis in vitro showed that after a few days of coculture, 3T3-L1 adipocytes were reduced in number and size with an increase in lipolysis rate and dedifferentiation phenomena. CONCLUSIONS: This study reveals important morphological and functional changes in the AT surrounding the tumor as an increase in lipolysis and in adiponectin-producing adipocytes, preferentially infiltrated by a macrophage subset, with prevalent reparative inflammatory response.
