Comparative Study of Chemoembolization, Loadable Beads: In vitro Drug Release and Physical Properties of DC Bead and Hepasphere, Loaded with Doxorubicin and Irinotecan

Purpose To characterize in vitro the loadability, physical properties, and release of irinotecan and doxorubicin from two commercially available embolization microspheres. Materials and Methods DC Bead (500-700 μm) and Hepasphere (400-600 μm) microspheres were loaded with either doxorubicin or irinotecan solutions. Drug amount was quantified with spectrophotometry, bead elasticity was measured under compression, and bead size and loading homogeneity were assessed with microscopy image analysis. Drug release was measured over 1-week periods in saline by using a pharmacopeia flow-through method. Results Almost complete drug loading was obtained for both microsphere types and drugs. Doxorubicin-loaded DC Beads maintained their spherical shape throughout the release. In contrast, Hepaspheres showed less homogeneous doxorubicin loading and, after release, some fractured microspheres. Incomplete doxorubicin release was observed in saline over 1 week (27% ± 2 for DC beads and 18% ± 7 for Hepaspheres; P = .013). About 75% of this amount was released within 2.2 hours for both beads. For irinotecan, complete release was obtained for both types of beads, in a sustained manner over 2-3 hours for DC Beads, and in a significantly faster manner as a 7-minute burst for Hepaspheres. Conclusions The two drug-eluting microspheres could be efficiently loaded with both drugs. Incomplete doxorubicin release was attributed to strong drug-bead ionic interactions. Weaker interactions were observed with irinotecan, which led to faster drug release.

Phenotypes influencing low physical activity in maintenance dialysis.

OBJECTIVE: The "Pas à Pas" initiative aimed at evaluating the weekly physical activity (PA) and its determinants in a large cohort of dialysis patients. SETTING: Physical inactivity is a risk factor for mortality in maintenance dialysis patients and is still poorly documented in this population. DESIGN: A prospective national epidemiological study was performed. SUBJECTS: A total of 1,163 patients on maintenance dialysis (hemodialysis and peritoneal dialysis) were included. INTERVENTION AND MAIN OUTCOME MEASURE: PA was recorded during seven consecutive days using a pedometer to measure daily step numbers. RESULTS: Median age was 63 years (Q1 51-Q3 75). Sixty-three percent were sedentary (<5000 steps/day) with a median of 3,688 steps/day (1,866-6,271)]. PA level was similar between hemodialysis patients and those on peritoneal dialysis (3,693 steps [1,896-6,307] vs. 3,320 [1,478-5,926], P = .33). In hemodialysis patients, PA was lower on dialysis days compared with nondialysis days (2,912 [1,439-5,232] vs. 4,054 [2,136-7,108], respectively, P < .01). PA gradually decreased with age, 57% being sedentary between 50 and 65 years and 83% of patients after 80 years. Beyond this age effect, we identified, for the first time, specific phenotypes of patients with lower PA, such as inflammation, cardiovascular disease, protein energy wasting, obesity, and diabetes. By contrast, previous kidney transplantation and a higher muscle mass were associated with higher PA. CONCLUSIONS: Dialysis patients present a very low level of PA with high sedentary. Acting on patient's modifiable phenotypes may help to increase PA to improve morbidity, mortality, and quality of life.

DIAfit, un programme suisse pour promouvoir l'activité physique chez les patients avec diabète de type 2 [DIAfit, a Swiss program encouraging physical activity in patients with type 2 diabetes].

Physical activity has a beneficial effect on the cardiovascular risk and the well-being in patients with type 2 diabetes. Thereby, both aerobic physical activities and resistance activities are recommended. DIAfit is a programm for patients with type 2 diabetes that is being implemented in Switzerland. Its objective is to allow the initiation of a structured physical activity in the setting of a pluridisciplinary team to promote a healthy lifestyle.

De l'invalide à l'adunatos: réflexions sur l'invalidité et le trouble somatoforme douloureux [From disability to the adunatos: some thoughts on disability and somatoform pain disorder].

Disability, especially if related to a psychiatric disorder, such as somatoform pain disorder, is characterized by medical, psychological, relational, social and societal, as well as financial and political aspects. This manuscript, part of a PhD thesis which reflects on a possible dialogue between an ancient text and the modern conceptualization of disability, tries to address the phenomenological, historical and political dimensions of disability.

Development and validation of the Family Vulnerability Index to Disability and Dependence (FVI-DD)

This exploratory, descriptive, cross-sectional, and quantitative study aimed to develop and validate an index of family vulnerability to disability and dependence (FVI-DD). This study was adapted from the Family Development Index, with the addition of social and health indicators of disability and dependence. The instrument was applied to 248 families in the city of Sao Paulo, followed by exploratory factor analysis. Factor validation was performed using the concurrent and discriminant validity of the Lawton scale and Katz Index. The descriptive level adopted for the study was p < 0.05. The final vulnerability index comprised 50 questions classified into seven factors contemplating social and health dimensions, and this index exhibited good internal consistency (Cronbach’s alpha = 0.82). FVI-DD was validated using both the Lawton scale and Katz Index. We conclude that FVI-DD can accurately and reliably assess family vulnerability to disability and dependence.

Insomnia Symptoms, Daytime Naps And Physical Leisure Activities In The Elderly: FIBRA Study Campinas

The practice of physical activities contributes to reducing the risk of chronic diseases and improves sleep patterns in the elderly. This research aimed to investigate the association between insomnia symptoms and daytime nap and the participation in physical leisure activities in elderly community residents. Data from the Studies Network of the Fragility in Brazilian Elderly (Campinas site), were used. Information from 689 elderly was analyzed, regarding sociodemographic characterization, physical leisure activity, occurrence of daytime napping and its duration, symptoms of insomnia and use of sleep medication. A significant association was found between the practice of walking and the daytime nap of short duration. Studies indicate that a short nap can benefit the quality of sleep and health of the elderly. Therefore, promoting the practice of walking can be a nursing intervention that favors the sleep patterns of the elderly.


Analysis of the physical aspects of quality of life of kidney recipients

OBJECTIVE To identify the main factors of the physical domain modified after kidney transplantation and analyze the influence of those aspects in the perception of Overall quality of life (QOL). METHOD Longitudinal study, conducted with 63 chronic kidney patients, evaluated before and after kidney transplant, using the quality of life scale proposed by the World Health Organization. RESULTS We observed significant improvement in the physical aspects of QOL after kidney transplantation. Significant correlations were observed between physical aspects and the Overall QOL. CONCLUSION The kidney transplant generated improvement in all physical aspects of QOL. The factors that showed stronger correlation with the Overall QOL before the transplant were the capacity to work and pain. After the transplant, the perception of need for treatment was the factor that showed stronger correlation with the Overall QOL.

Contributory factors for the functional independence of oldest old

OBJECTIVE To investigate the socioeconomic and clinical factors that contribute to the functional independence of the oldest old of a community. METHOD Cross-sectional quantitative study whose sample consisted of 214 elderly people registered in Basic Health Units. Data were collected through structured interviews and application of the Functional Independence Measure. We used descriptive statistics, and for association of the variables we used the Student t-test, ANOVA and Tukey's test for multiple comparisons. RESULTS The significant variables that contributed to the functional independence were remaining economically active, practicing physical and leisure activities, having a social life, eating fruits, vegetables and meat. The orientation to conduct these practices reduces the demand for care and help needed in everyday activities. CONCLUSION Maintaining independence is primordial to delay disability and presents itself as an excellent field of work for nursing.
