Objective: There are few quantitative studies on art therapy for the treatment of depression. The objective of this study was to evaluate if art therapy is beneficial as an adjuvant treatment for depression in the elderly. Methods: A randomized, controlled, single-blind study was carried out in a sample of elderly women with major depressive disorder (MDD) stable on pharmacotherapy. The experimental group (EG) was assigned to 20 weekly art therapy sessions (90 min/session). The control group (CG) was not subjected to any adjuvant intervention. Patients were evaluated at baseline and after 20 weeks, using the Geriatric Depression Scale (GDS), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and cognitive measures. Results: Logistic regression analysis adjusted for age revealed that women in EG (n=31) had significant improvement in GDS (p = 0.007), BDI (p = 0.025), and BAI (p = 0.032) scores as compared with controls (n=25). No difference was found in the cognitive measures. Conclusion: Art therapy as an adjunctive treatment for MDD in the elderly can improve depressive and anxiety symptoms. Clinical trial registration: RBR-2YXY7Z

A intoxicação por plantas do gênero Senecio é a principal causa de morte de bovinos na região central do Rio Grande do Sul. Neste trabalho, relata-se um surto de intoxicação por Senecio brasiliensis em bovinos com alta prevalência de fotossensibilização, onde 83 vacas de um total de 162 (51,3%) apresentaram esse sinal clínico. O surto ocorreu em setembro a outubro de 2013, acometendo vacas adultas que foram colocadas de abril a início de outubro de 2013 em um campo de 205 hectares com abundante infestação por Senecio brasiliensis. Os principais sinais clínicos foram emagrecimento, lacrimejamento excessivo ou secreção ocular mucopurulenta, secreção nasal serosa, glossite diftérica ventral e crostas no plano nasal, tetos, ponta das orelhas e na vulva. Realizou-se biópsia hepática em todas as vacas do rebanho; os principais achados histopatológicos nas bipósias hepáticas foram fibrose hepática, megalocitose e proliferação de ductos biliares. As lesões hepáticas foram observadas em 73,4% dos bovinos submetidos à biópsia hepáica. Seis vacas testadas apresentaram aumento da atividade sérica da gama glutamil transferase. Três vacas doentes foram necropsiadas. Nas vacas necropsiadas, o fígado era firme, a vesícula biliar distendida e havia edema do mesentério e do abomaso. As lesões histológicas observadas nos fígados dos bovinos necropsiados eram semelhantes às encontradas nas biópsias hepáticas. Espongiose foi detectada no cérebro das vacas necropsiadas e é uma lesão característica de encefalopatia hepática.

Senecio spp. poisoning is the main cause of cattle mortality in the central region of Rio Grande do Sul. This paper reports an outbreak of seneciosis in cattle with high prevalence of photosensitization, where 83 out of 162 cows (51.3%) presented this clinical sign. The outbreak occurred in September 2013, affecting adult cows that were held in a 205 hectare-pasture from April to October 2013 with abundant Senecio brasiliensis infestation. Main clinical signs were weight loss, excessive lacrimation or mucopurulent ocular discharge, nasal serous discharge, ventral diphteric glossitis, crusts in the nose, teats, dorsum of ears, and vulva. Liver biopsy was performed in all the cows under risk; the histopathological findings in the liver biopsies consisted of fibrosis, megalocytosis, and biliary ductal proliferation and were present in 73.4% of the biopsied animals. Six cows had increased serum activity of gamma glutamyl transferase. Three affected cows were necropsied. The main necropsy findings were a hard liver, distended gall bladder, edema of the mesentery and abomasum. Liver histological changes in the necropsied cows were similar to those of the biopsied livers. Spongiosis was detected in the brain of necropsied cows and is characteristic of hepatic encephalopathy.

Dermatite tem sido observada em bovinos no Uruguai e no Rio Grande do Sul que são suplementados com farelo de arroz desengordurado em quantidade equivalente a 1% do peso corporal. Descreve-se um surto de dermatite associada ao consumo de farelo de arroz desengordurado em um município do interior do Rio Grande do Sul. Do total de 26 bovinos, com três anos de idade, sete apresentaram lesões que foram observadas após 24 dias de ingestão da ração de farelo de arroz desengordurado. As lesões eram observadas na extremidade distal dos membros posteriores e se caracterizavam por áreas de alopecia, com acentuado espessamento da epiderme, formando crostas secas, espessas e fissuradas. A lesão histológica observada nestes casos foi caracterizada como dermatite perivascular superficial crônica focalmente extensa moderada, com acantose irregular e formação de crosta serocelular. As lesões macro e microscópicas observadas, juntamente com os dados epidemiológicos, permitem concluir o diagnóstico de dermatite associada ao consumo de farelo de arroz desengordurado. As lesões histológicas, embora não patognomônicas, são descritas nesta doença.

Dermatitis has been observed in Uruguay and Rio Grande do Sul, in cattle supplemented with defatted rice bran in an amounts equivalent to 1% of body weight. An outbreak of dermatitis in cattle associated with consumption of defatted rice bran in Rio Grande do Sul, is herein described. Out of a total of 26 3-year-old cattle consuming this ration, seven had lesions that were observed after 24 days on the ration. The lesions were observed in the distal hind limbs and were characterized by areas of alopecia with marked thickening of the epidermis with crust formation imparting a thicken and fissured aspect to the skin. The histological lesions observed in these cases were characterized as moderate superficial perivascular chronic dermatitis focally extensive, with irregular acanthosis and serocellular crusting. The gross lesions observed, together with epidemiological data, allow for a diagnosis of dermatitis associated with the consumption of defatted rice bran. Histologic changes, although not pathognomonic, are typically described in this disease.

OBJECTIVE: To evaluate the effects of a multidisciplinary rehabilitation program on cognition, quality of life, and neuropsychiatry symptoms in patients with mild Alzheimer's disease. METHOD: The present study was a single-blind, controlled study that was conducted at a university-based day-hospital memory facility. The study included 25 Alzheimer's patients and their caregivers and involved a 12-week stimulation and psychoeducational program. The comparison group consisted of 16 Alzheimer's patients in waiting lists for future intervention. INTERVENTION: Group sessions were provided by a multiprofessional team and included memory training, computer-assisted cognitive stimulation, expressive activities (painting, verbal expression, writing), physiotherapy, and physical training. Treatment was administered twice a week during 6.5-h gatherings. MEASUREMENTS: The assessment battery comprised the following tests: Mini-Mental State Examination, Short Cognitive Test, Quality of Life in Alzheimer's disease, Neuropsychiatric Inventory, and Geriatric Depression Scale. Test scores were evaluated at baseline and the end of the study by raters who were blinded to the group assignments. RESULTS: Measurements of global cognitive function and performance on attention tasks indicated that patients in the experimental group remained stable, whereas controls displayed mild but significant worsening. The intervention was associated with reduced depression symptoms for patients and caregivers and decreased neuropsychiatric symptoms in Alzheimer's subjects. The treatment was also beneficial for the patients' quality of life. CONCLUSION: This multimodal rehabilitation program was associated with cognitive stability and significant improvements in the quality of life for Alzheimer's patients. We also observed a significant decrease in depressive symptoms and caregiver burden. These results support the notion that structured nonpharmacological interventions can yield adjunct and clinically relevant benefits in dementia treatment.
