Does the type of sedentary behaviors influence blood pressure in adolescents boys and girls? A cross-sectional study

The aim of this study was to analyze the association between different sedentary behaviors and high blood pressure in adolescent boys and girls. We conducted a cross-sectional study with 6,264 Brazilian adolescents (14 to 19 years old). Demographic data, obesity indicators and blood pressure, were evaluated. Time spent in the sedentary behaviors (television viewing, playing video games, using the computer, non-screen sitting and, total time sitting) were also assessed. The girls spent more time watching television than boys, whereas boys spent more time using computers and video games (12.7% vs. 7.4%, p 0.05). Television viewing time is associated with high blood pressure only boys. So, reduce this sedentary behavior, stimulating physical activities, might be essential to health, principally for male adolescents.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Univ Pernambuco, Av Gov Agamenon Magalhaes, BR-50100010 Recife, PE, BrazilUniv Nove Julho, Sao Paulo, SP, BrazilUniv Fed Pernambuco, Hosp Clin, Unidade Tele Saude, Recife, PE, BrazilUniv Estadual Paulista, Lab Invest Exercicio, Dept Educ Fis, Presidente Prudente, SP, BrazilUniv Estadual Paulista, Lab Invest Exercicio, Dept Educ Fis, Presidente Prudente, SP, Brazi

Sucção do recém-nascido prematuro: comparação do método Mãe-Canguru com os cuidados tradicionais Suckling of the premature newborn child: comparison between the Kangaroo Mother method with traditional care

OBJETIVOS: comparar o processo de sucção em recém-nascidos prematuros incluídos no método Mãe-Canguru com recém-nascidos submetidos aos cuidados tradicionais. MÉTODOS: foram selecionados 30 recém-nascidos prematuros com idade gestacional entre 30 e 35 semanas. A amostra foi constituída de dois grupos: Grupo 1, composto por 16 recém-nascidos inseridos no Alojamento Mãe-Canguru da Maternidade Escola Assis Chateaubriand e Grupo 2, constituído por 14 recém-nascidos submetidos aos cuidados tradicionais, ou seja, Berçário de Médio Risco do Hospital Geral de Fortaleza. Todos os recém-nascidos foram avaliados, submetidos à intervenção fonoaudiológica e reavaliados durante a alta hospitalar. RESULTADOS: no Grupo 1 houve uma melhora significativa em relação ao estado comportamental, sinais de estresse, coordenação e ritmo de sucção. O tempo de permanência hospitalar foi consideravelmente menor. No Grupo 2 foi verificada uma melhora significativa em relação à coordenação entre sucção, deglutição e respiração. CONCLUSÕES: os recém-nascidos de ambos os grupos foram beneficiados com a intervenção fonoaudiológica, no entanto, os melhores resultados foram referentes ao método Mãe-Canguru. Verificou-se que esse método constitui uma ótima alternativa para países em desenvolvimento, pois contribui para a efetividade da amamentação, diminuindo o tempo de permanência hospitalar, acarretando menores custos para a saúde pública.<br>OBJECTIVES: to compare premature newborns' suction in the Mother-Kangoroo method with newborns submitted to traditional care. METHODS: thirty premature newborns with gestational age between 30 and 35 weeks were selected. The samples were comprised of two groups: Group 1: 16 newborns of the Mother Kangoroo Ward of the Maternity School Assis Chateaubriand and Group 2: formed by 14 newborns submitted to traditional care, i.e. Medium Risk Nursery of the General Hospital of Fortaleza. All newborns were evaluated and submitted to phoniatric intervention in the process of hospital discharge. RESULTS: in Group 1 there was a significant improvement related to behavior, stress signs, coordination and suction rhythm. Hospital stay was considerably shorter. In group 2 there was a significant improvement related to the coordination between suction, deglutition and breathing. CONCLUSIONS: newborns of both groups were benefited by phoniatrics, nevertheless, the best results related to the Kangaroo-Mother Method. It has been noted that this method is a good alternative for developing countries for it contributes to the effectiveness of nursing, shortening hospital stay and reducing public health costs

Histopathological characteristics of cutaneous lesions caused by Leishmania Viannia panamensis in Panama

ABSTRACT Cutaneous leishmaniasis (CL) is an endemic disease in the Republic of Panama, caused by Leishmania (Viannia) parasites, whose most common clinical manifestation is the presence of ulcerated lesions on the skin. These lesions usually present a chronic inflammatory reaction, sometimes granulomatous, with the presence of lymphocytes, plasma cells and macrophages. This study describes the histopathological characteristics found in the skin lesions of patients with CL caused by Leishmania (V.) panamensis in Panama. We analyzed 49 skin biopsy samples from patients with clinical suspicion of CL, by molecular tests (PCR for subgenus Viannia and HSP-70) and by Hematoxylin-Eosin staining. Samples were characterized at the species level by PCR-HSP-70/RFLP. From the 49 samples studied, 46 (94%) were positive by PCR and were characterized as Leishmania (V.) panamensis. Of these, 48% were positive by Hematoxylin-Eosin staining with alterations being observed both, in the epidermis (85%) and in the dermis (100%) of skin biopsies. The inflammatory infiltrate was characterized according to histopathological patterns: lymphohistiocytic (50%), lymphoplasmacytic (61%) and granulomatous (46%) infiltration, being the combination of these patterns frequently found. The predominant histopathological characteristics observed in CL lesions caused by L. (V.) panamensis in Panama were: an intense inflammatory reaction in the dermis with a combination of lymphohistiocytic, lymphoplasmacytic and granulomatous presentation patterns and the presence of ulcers, acanthosis, exocytosis and spongiosis in the epidermis
