Influência da dor na capacidade funcional de idosos institucionalizados

The aim of this study was to evaluate the pain influence regarding location, intensity and duration over functional capacity in institutionalized elderly (Fundacao Leur Brito). This is a descriptive exploratory study with a transversal design and quantitative approach. The population of the study was composed of 60 elderly, being 50% males with 60 years-old minimum age and 104 years-old maximum age, with mean age 77,6 (?}11,64) years-old. Data was collected by a structured query formulary divided in four parts: 1) Social, health and demographic characterization; 2) Pain related aspects (time and location); 3) Pain evaluation by numeric scale and 4) Functional capacity measured by Barthel Index. It was observed after evaluation by Squared-chi test (x2) statistical significant difference between pain presence and Barthel Index activities: bath (pvalue=0,015), dressing (p-value= 0,041), intimal hygiene transference (p-value=0,001), chair and bed transference (p-value=0,032), walking (p-value=0,010) and go upstairs (p-value=0,008). It was also observed statistical difference between total Barthel score (dependent/independent) and pain presence, p-value<0, 000. Through data obtained by this study, a multiprofessional approach is necessary to proper pain control and maintenance and/or regain of functional capacity, leading to an increase in life quality with more independence and autonomy to elderly

Efeito do ácido ascórbico sobre a espermatogênese de camundongos com distrofia muscular de Duchenne

The objective was to evaluate spermatogenesis alterations caused by DMD and the effect of the treatment using ascorbic acid in preventing those injuries. Twenty four mice were used, 12 from the C57BL/10 lineage (non-dystrophic) and 12 from the C57BL/10Mdx (dystrophic). The sample was divided in six groups containing 4 animals each, as: C30 = 30 days control; D30 = Dystrophic with 30 days; C60 = 60 days control; D60 = Distrophic with 60 days; CS60 = 60 days control supplemented with ascorbic acid and DS60 = Dystrophic with 60 days supplemented with ascorbic acid. The ascorbic acid supplementation was given in the water, 0,005 mg/day. After euthanasia, the testicles (right and left) were collected, weighted and cross sectioned. The material was fixed in the Karnovsky solution for 24 hours, included in resin for histological studies (morphological and morphometric analyzes) submitted to ultrastructural analysis and immunohistochemistry for caspase-3. There was a significant increase in the tunica propria percentage in D30 compared to C30 and D60. The ultrastructural analysis showed mitochondrial apoptosis evidence of Sertoli cells that can reduce sperm efficiency in CS60 and DS60. A higher volume density of apoptotic cells postivas to Caspase-3 in C30 and D30 versus DS60 compared to CS60. There was severe hypertrophy of the Leydig cells between D30 and D60. However, with supplementation was observed reversal of this change in DS60. The ultrastructure of Leydig cells to early presence of lipid vesicles was observed in the group pre-pubertal dystrophic (D30). Thus, the DMD affect the organization of the seminiferous tubules and intertubule, however, the ascorbic acid supplementation used for the treatment of DMD has been just enough to reduce the hypertrophy of the Leydig cells.
