ANALYSIS OF FUNCTIONAL STATUS OF ELDERLY RESIDENTS IN LONG-TERM CARE INSTITUTIONS

Objective: To evaluate the functional status of elderly residents in long-term institutions. Methods: Exploratory-descriptive study, developed in two long-term care institutions for the elderly (LTC), in city of Fortaleza, Ceará. The instruments utilized were: 1) Sociodemographic form, 2) Functional Independence Measure (FIM), and 3) International Classification of Functioning (ICF). Data was descriptively analyzed through the calculation of frequency, mean and standard deviation. Results: There was a predominance of males (n=47; 59.49%), with mean age of 74.58 (± 8.89) years, 68.35% (n=54) have been or are married, and 49.37% (n=39) are illiterate. In reference to the FIM, it was observed that the elderly perform the activities in a complete or modified mode and 18.99% (n=15) have difficulty climbing stairs. As to the association between the FIM and the ICF, in relation to self-care, it was seen that 96.20% (n=76) have no difficulty in performing tasks; 92.40% (n=73) move around without difficulty; and 98.73% (n=78) have preserved the cognition. In relation to the capacity of maintaining and controlling social interactions, all exhibit this domain preserved. Conclusion: The surveyed elderly presented good cognitive status and little dependence in activities regarding personal care, mobility and communication. The use of the ICF allows the visualization of the functionality scenario among the elderly, what can facilitate more effective health promotion strategies for this population.

Cadmium phytoextraction capacity of white lupine ( Lupinus albus L.) and narrow-leafed lupine ( Lupinus angustifolius L.) in three contrasting agroclimatic conditions of Chile

The phytoextraction process implies the use of plants to promote the elimination of metal contaminants in the soil. In fact, metal-accumulating plants are planted or transplanted in metal-contaminated soil and cultivated in accordance with established agricultural practices. The objective of the present study was to evaluate the productivity and Cd phytoextraction capacity of white lupine ( Lupinus albus L.) and narrow-leafed lupine ( Lupinus angustifolius L.), as well as the effect on residual Cd concentration in the soil. Both species of lupines were grown at three CdCl2 rates (0, 1, and 2 mg kg-1), under three agroclimatic conditions in Chile in 2013. In the arid zone (Pan de Azúcar, 73 mm precipitation), narrow-leafed lupine production was significantly (P < 0.05) higher than white lupine (4.55 vs. 3.26 Mg DM ha-1, respectively). In locations with higher precipitation (Santa Rosa, 670 mm; Carillanca, 880 mm), narrow-leafed lupine DM production was slightly higher than in Pan de Azúcar, but white lupine was approximately three times higher. Total plant Cd concentrations in white and narrow-leafed lupine increased as Cd rates increased in the three environments, but they were much higher in narrow-leafed lupine than white lupine; 150%, 58%, and 344% higher in Pan de Azúcar, Santa Rosa, and Carillanca, respectively. Cadmium uptake (g Cd ha-1) and apparent recovery were also higher (P < 0.05) in narrow-leafed lupine in two environments (Pan de Azúcar and Carillanca). These results suggest that narrow-leafed lupine present higher potential as phytoremediation species than white lupine.

Early Adaptation of Small Intestine After Massive Small Bowel Resection in Rats

Background: It is important that the residual bowel adapts after massive resection. The necessary intestinal adaptation is a progressive recovery from intestinal failure through increase in absorptive surface area and functional capacity and includes both morphological and functional adaptations. Objectives: The aim of this study was to investigate intestinal morphological and functional adaptations of small bowel syndrome (SBS) model rats (SBS1W) 7 days after bowel resection. Materials and Methods: Male sprague–dawley rats (n = 20/group) underwent either a 75% proximal small bowel resection (SBS1W group) or a control operation (control group). Markers of morphological adaptation were revealed by TEM analysis of H&E-stained tissue samples. The intestinal barrier condition was assessed by BT, and sIgA concentration in intestinal mucus was measured by ELISA. Contractility and the slow wave rhythm of the entire intestinal remnant were measured and recorded. Results: The SBS1W group experienced more weight loss than control group and had a clearly different intestinal morphology as revealed in TEM images. Compared with control rats, the SBS1W group had a lower sIgA concentration in intestinal mucus and higher BT to lymph nodes (70% vs 40%; level I), portal blood (40% vs 10%; level II), and peripheral blood (60% vs 30%; level III). Disorder of spontaneous rhythmic contraction, irregular amplitude, and slow frequency were detected in the SBS1W group by a muscle strips test. Similarly, the slow wave of the entire intestinal remnant in the SBS1W group was irregular and uncoordinated. Conclusions: The finding of intestinal adaptation following massive SBR in SBS1W rats provides more understanding of the mechanisms of progressive recovery from the intestinal failure that underlies SBS. The mechanical, chemical, immunological, and biological barriers were all impaired at 7 days following bowel resection, indicating that the SBS model rats were still in the intestinal adaptation phase.
