Nursing care for migrant and refugee families: emerging issue

The impact of migratory movements is, worldwide, an emerging theme for nursing because of the health implications of individuals and their migrant or refugee families. These movements, whether voluntary or involuntary, are motivated by social, economic, cultural, religious or environmental factors.1International migration is a concern for achieving the goals of the Sustainable Development Agenda 2030 and it is estimated that 258 million people live in a country other than their birth, of which 68.5 million are refugees and represents an increase of 49% since 2000.2The terms migrants and refugees are used interchangeably, but their meanings are different. Refugees are out of their country of origin because they fear persecution, conflict, violence or other circumstances that impose the need for "international protection." Already, migrant individuals live a voluntary process; for example, someone who crosses a border in search of better economic opportunities.3These movements bring significant socio-cultural impacts related to the abandonment of material goods; loss of employment; undocumented status, food insecurity, increased morbidity and mortality. In addition, the process of acculturation involves the rupture of social networks, changes in the way of life, uprooting, humiliation and the sensation of not belonging to any place. These are barriers that influence the level of health of families.4

Plantas medicinais utilizadas por idosos com diagnóstico de Diabetes mellitus no tratamento dos sintomas da doença / Medicinal plants used by elderly people with Diabetes mellitus in the treatment of the disease symptoms

Este trabalho teve como objetivo investigar as plantas medicinais utilizadas por idosos assistidos em uma Unidade Básica de Saúde de Pelotas-RS, com diagnóstico de Diabetes mellitus, como terapia complementar no tratamento dos sintomas da doença. Caracterizou-se por pesquisa qualitativa, realizada em julho de 2009, no município de Pelotas-RS. Foram entrevistados 18 idosos com idade entre 60 e 77 anos, sendo 14 do sexo feminino. Os participantes citaram 20 plantas medicinais utilizadas como terapia complementar no tratamento do Diabetes mellitus. Entre estas, as mais citadas utilizadas para diminuir os níveis de glicose no sangue foram Sphagneticola trilobata, Bauhinia spp. e Syzygium cumini, sendo que para as duas últimas há comprovação científica do efeito hipoglicemiante. A infusão foi a forma de preparo predominante. Considera-se importante a realização de estudos farmacológicos que investiguem os efeitos das plantas utilizadas pela população, a fim de que o uso proporcione os benefícios desejados e não cause danos à saúde.

This study aimed to investigate medicinal plants used as complementary therapy by the elderly with diabetes mellitus, assisted by a Health Basic Unit in Pelotas (RS, Brazil). This qualitative research was conducted in July 2009. Eighteen 60 to 77 years old elderly (14 of them female) were interviewed. The participants identified 20 medicinal plants used as complementary therapies in the treatment of diabetes mellitus. Among these, the most used ones to reduce the levels of glucose in the blood were Sphagneticola trilobata, Bauhinia spp. and Syzygium cumini. For the last two plants, there are scientific proofs of hypoglycemic effects. The infusion was the predominant form of preparation. Studies to investigate the pharmacological effects of plants used by the population have become very important, for providing scientific information on their possible health benefits and side effects.

Skin secretion of Siphonops paulensis (Gymnophiona, Amphibia) forms voltage-dependent ionic channels in lipid membranes

The effect of the skin secretion of the amphibian Siphonops paulensis was investigated by monitoring the changes in conductance of an artificial planar lipid bilayer. Skin secretion was obtained by exposure of the animals to ether-saturated air, and then rinsing the animals with distilled water. Artificial lipid bilayers were obtained by spreading a solution of azolectin over an aperture of a Delrin cup inserted into a cut-away polyvinyl chloride block. In 9 of 12 experiments, the addition of the skin secretion to lipid bilayers displayed voltage-dependent channels with average unitary conductance of 258 ± 41.67 pS, rather than nonspecific changes in bilayer conductance. These channels were not sensitive to 4-acetamido-4'-isothiocyanatostilbene-2,2'-disulfonic acid or tetraethylammonium ion, but the experimental protocol used does not permit us to specify their characteristics

Tratamiento endovascular del aneurisma de aorta torácica descendente / Endovascular treatment of descending thoracic aorta aneurysm

BACKGROUND: The natural history of aneurysms ends in rupture and death. In 1990 the first endovascular exclusion of an aneurysm, using an endoluminal graft implanted through the femoral arteries was performed. More recently, the same procedure has been used for aneurysms of the thoracic aorta. AIM: To report our experience with endovascular treatment of thoracic aorta aneurysms. MATERIAL AND METHODS: Analysis of 14 patients (nine male), aged 30 to 79 years, treated between May 2001 and August 2002. RESULTS: The mean diameter of the aneurysms was 6.9 cm. The etiology was atherosclerotic in nine patients. The Excluder device (Gore) was preferentially used. There was no operative mortality or paraplegia. One patient had a transient leg monoparesis that reverted completely. No patient had type I endoleaks. Two patients had type II endoleaks on discharge, that sealed spontaneously. In a follow up, ranging from 2 to 17 months, one patient died of a bronchopneumonia and no aneurysm rupture has been detected. CONCLUSIONS: The short term results of endoluminal treatment of thoracic aorta aneurysms are excellent. This treatment is less invasive and has less complications than conventional surgery.
