Perfil dos pacientes e carga de trabalho de enfermagem na unidade de nefrologia

Chronic kidney failure (CKF), which is frequently silent, can lead to considerable changes in the lives of patients. Depending on the stage, hospitalization and hours of nursing care are required to ensure medical and surgical treatment. The aim of this descriptive and quantitative study is to measure nursing workload at a nephrology unit based on daily application of the Nursing Activities Score (NAS) for 47 consecutive days. Patients were mostly young male adults in the chronic stage of the disease or admitted for kidney transplant. A total of 833 observations were obtained from 62 patients. The resulting NAS workload upon admission was 52%, corresponding to 12.5 hours of care per patient for 24 hours, which is similar to the workload found in intensive care units. This profile allows calculation of nursing work hours required for each patient and is a valuable tool for nursing managers when determining the number of staff members required to ensure assistance. Other studies should be conducted for clinical validation.

The taxonomic status of Myotis levis levis and Myotis levis dinellii (Mammalia: Chiroptera: Vespertilionidae)

Investigating the Myotis levis complex is important for understanding the taxonomic status of the two subspecies currently recognized in it: Myotis levis levis (I. Geoffroy, 1824) and M. levis dinellii Thomas, 1902. Both M. levis levis and M. levis dinellii have been recently observed in sympatry in Argentina. This finding suggests that these populations might in fact correspond to distinct species rather than subspecies, as they have traditionally been designated. By using a multivariate morphometric approach, we demonstrate that M. l. levis has secondary sexual dimorphism in several measurements, with females being larger than males; sexual dimorphism was not detected in M. levis dinellii. However, we found morphometric differences between the two taxa. These differences exceeded those documented for other Neotropical Myotis. Based on their sympatry, morphological, and morphometrical differences, we propose a change in the status of both subspecies to M. levis and M. dinellii

Simultaneous determination of ethinyl estradiol and drospirenone in oral contraceptive by high performance liquid chromatography

A simple, rapid, economical and reliable high performance liquid chromatographic method has been developed and successfully applied in simultaneous determination of ethinyl estradiol and drospirenone in coated tablets. The HPLC method was performed on a LiChroCART® 100RP column (125x4 mm i.d., 5 µm) with acetonitrile:water 50:50 (v/v) as mobile phase, pumped at a flow rate of 1.0 mL.min-1. The fluorescence detection for ethinyl estradiol was made at λex= 280 nm and λem= 310 nm and a UV detection for drospirenone was made at 200 nm. The elution time for ethinyl estradiol and drospirenone were 4.0 and 5.7 min, respectively. The method was validated in accordance to USP 34 guidelines. The proposed HPLC method presented advantages over reported methods and is suitable for quality control assays of ethinyl estradiol and drospirenone in coated tablets

The influence of protective varnish on the integrity of orthodontic cements

The aim of the present study was to assess the influence of saliva contamination over the structural strength and integrity of conventional glass-ionomer cements used for cementing orthodontic bands in the absence and presence of a surface-protecting varnish.

Avaliação muito tardia do uso de stents farmacológicos para tratamento de pacientes com lesões em enxertos de veia safena: experiência de uma década do Registro DESIRE

Denervação simpática renal percutânea

A hipertensao arterial sistemica (HAS) e uma doenca de alta prevalencia e esta comprovadamente relacionada a maior risco de eventos cardiovasculares. Apesar dos grandes avancos no tratamento farmacologico, uma parcela consideravel dos pacientes nao obtem um controle efetivo da doenca, a despeito do uso de multiplos farmacos e em doses elevadas. A denervacao simpatica renal percutânea (DSRP) tem se mostrado uma terapia promissora, com elevada seguranca e eficacia em estudos preliminares em pacientes com HAS resistente. O papel do sistema nervoso simpatico na fisiopatologia da HAS e bem conhecido e constitui o racional para a ablacao das fibras simpaticas, por meio da aplicacao de radiofrequencia por via transluminal nas arterias renais. Nos ultimos anos, resultados provenientes de algumas series de casos, estudos nao controlados e um estudo randomizado multicentrico, com numero limitado de pacientes, mostraram queda significativa dos niveis tensionais em curto e medio prazos. Esta revisao teve por objetivo reunir as evidencias do uso da DSRP no controle da HAS resistente de maneira critica, assim como descrever aspectos tecnicos do procedimento e perspectivas.

Adult Growth in Opilioacaridae with 1904 (Acari: Parasitiformes: Opilioacarida)

Mites in the order Opilioacarida are known to undergo postimaginal molting. The process has been associated with the ability to regain lost appendages, but may also result in growth and increases in numbers of specific setae. These processes were observed in four individuals, with two of these showing increases in setal lengths ranging from 8.1 to 16.6%. Qualitative growth, in the form of an increase from 5 to 6 in the number of d-type setae on the left palp, was observed in a single individual.

The Great East-Japan Earthquake and Devastating Tsunami: An Update and Lessons from the Past Great Earthquakes in Japan since 1923

Japan has a long history of fighting against great earthquakes that cause structural damage/collapses, fires and/or tsunami. On March 11, 2011 at 14:46 (Friday), the Great East-Japan Earthquake (magnitude 9.0) attacked the Tohoku region (northeastern Japan), which includes Sendai City. The earthquake generated a devastating tsunami, leading to unprecedented disasters (~18,500 victims) in coastal areas of Iwate, Miyagi and Fukushima prefectures, despite the fact that people living in the Tohoku region are well trained for tsunami-evacuation procedures, with the mindset of "Tsunami, ten-den-ko." This code means that each person should evacuate individually upon an earthquake. Sharing this rule, children and parents can escape separately from schools, houses or workplaces, without worrying about each other. The concept of ten-den-ko (individual evacuation) is helpful for people living in coastal areas of earthquake-prone zones around the world. It is also important to construct safe evacuation centers, because the March 11(th) tsunami killed people who had evacuated to evacuation sites. We summarize the current conditions of people living in the disaster-stricken areas, including the consequences of the Fukushima nuclear accident. We also describe the disaster responses as the publisher of the Tohoku Journal of Experimental Medicine (TJEM), located in Sendai, with online support from Tokyo. In 1923, the Great Kanto Earthquake (magnitude 7.9) evoked a massive fire that destroyed large areas of Tokyo (~105,000 victims), including the print company for TJEM, but the Wistar Institute printed three TJEM issues in 1923 in Philadelphia. Mutual aid relationships should be established between distant cities to survive future disasters.
