Prevention of nasal trauma due to CPAP in a preterm newborn: case report

The administration of continuous positive airway pressure through nasal CPAP has been used in the treatment of neonatal respiratory diseases as a means of providing ventilatory support to preterm infants, producing adequate gas exchange, decreasing the complications induced by invasive mechanical ventilation and reducing bronchopulmonary dysplasia. The nasal prong is the most common device used to connect to the airways with the purpose of providing mechanical ventilation. Nasal prongs are available in different sizes and made of lightweight and flexible material. Despite its advantages, this device can cause trauma to the nose causing nasal discomfort and disfigurement. We report the case of an extremely low birth weight preterm who used a system of nasal CPAP developed by the nurses of the Neonatal Intensive Care Unit of the HCPA to protect the skin, mucosa, and nasal septum. Protection was successful

Resistance exercise load reduction and exercise-induced micro-damage

High volumes of resistance exercise increase muscle hypertrophy, independent of the extent of muscle damage. We compared volume load and markers of muscle damage after resistance exercise using two load reduction strategies versus a constant intensity. Methods: Twenty-seven trained men (age = 23.4±3.5 years, body mass = 74.5±10.7 Kg, height = 174±8 cm, 10 RM = 211±40 Kg) completed one weekly bout of 4 sets of leg press exercise under three loading schemes in a randomized, counterbalanced order over a three-week period. The loading schemes were (a) constant load for all sets (CON), (b) 5% load reduction after each set (LR5), and (c) 10% load reduction after each set (LR10). Volume load, muscle soreness (SOR), and range of motion (ROM) at the knee were assessed after each bout. Results: Volume load was significantly different amongst all conditions (CON = 6799±1583 Kg; LR5 = 8753±1789 Kg; 10896±2262 Kg; F=31,731; p<0.001). ROM and SOR were significantly different among conditions, with LR5 and LR10 producing greater preservations of ROM (p =<0.001) and less SOR (p < 0.001). These data may support the use of load reductions when training for hypertrophy

Estratégias para reduzir a mortalidade embrionária em bovinos: II. Protocolo para reduzir a mortalidade embrionária em vacas de leite e em receptoras de embrião.

A mortalidade embrionária precoce é a maior causa de perdas reprodutivas em bovinos e ela relaciona-se, principalmente com os distúrbios do reconhecimento materno da prenhez originados em disfunções do corpo lúteo ovariano. Recentemente, foi desenvolvido na Embrapa Pecuária Sudeste, um protocolo hormonal que melhora a função luteínica e permite aumentar a oportunidade para um reconhecimento materno da prenhez bem sucedido. O protocolo baseia-se na administração de hormônios reprodutivos (GnRH e hCG) em ocasiões estratégicas após a ovulação. Foram realizados dois experimentos, um com vacas leiteiras e outro com receptoras de embrião, para testar e validar o uso desse protocolo. Após a aplicação do tratamento houve aumento nas taxas de prenhez. Os resultados detalhados do uso dessa prática estão descritos no presente Boletim de Pesquisa e Desenvolvimento. O protocolo testado traduz-se numa prática pecuária de controle das funções ovariana e uterina que otimiza a eficiência reprodutiva de vacas leiteiras e de receptoras de embrião.bitstream/item/43513/1/Boletim27.pd

Taxas de mortalidade entre os idosos de Belo Horizonte, 1996 e 2006: uma breve análise por sexo e principais causas de morte

In Brazil and all over the world, in parallel with the demographic transition, due to advances in medicine and health care, there has been an increase in the life expectancy and longevity of the elderly. This combination of factors causes changes in the pattern of morbidity and mortality which can be assessed by simple measures of both morbidity and mortality. In this study we used indicators of mortality (General mortality rates for the elderly and rates by age groups) for the elderly popula tion 65 years and more Belo Horizonte in 1996 and 2006. The main results are that (1) there is a trend of decrease of mortality rates of the elderly among the younger men and women for the most represented causes of death, (2) most often causes of death changed during the period, (3) differences could be observed for males and for females. Finally, it is important to emphasize that it is worrysome that ill defined causes of death were among the most common causes for men and women.Brazil, mortality

Qualidade microbiológica do arroz comercializado em Goiânia, Goiás.

Este trabalho teve como objetivos avaliar a qualidade sanitária de vários tipos e marcas de arroz, consumidos e comercializados em Goiânia, GO, por meio da quantificação de fungos totais e de bactérias mesófilas presentes nas amostras; verificar se existe diferença entre os tipos de arroz quanto à presença de microrganismos; verificar se a carga microbiana nas amostras de arroz aumenta com o tempo de armazenamento e identificar, em nível de gênero, os fungos desenvolvidos nas amostras, tanto pelo método blotter test quanto pelo plaqueamento em profundidade.bitstream/item/28999/1/doc261.pd
