Limited data exist on the comparison of blood pressure (BP) measurements using aneroid and oscillometric devices. The purpose of the study was to investigate the difference in BP obtained using oscillometric and aneroid BP monitors in 9‐ to 10‐year‐old children. A total of 979 children were divided into group O, which underwent two oscillometric BP readings followed by two aneroid readings, and group A, which had BP measured in the reverse order. No significant difference was found between the mean (±standard deviation) of the two systolic BP readings obtained using the oscillometric and aneroid devices (111.5±8.6 vs 111.3±8.1 mm Hg; P=.39), whereas the mean diastolic BP was lower with the oscillometric monitor (61.5±8.0 vs 64.5±6.8 mm Hg; P<.001). A significant downward trend in BP was observed with each consecutive measurement, and agreement between the two monitors was limited. Multiple BP measurements are, therefore, recommended before the diagnosis of elevated BP or hypertension is made with either method. 相似文献

A large body of literature suggests an inverse relationship between birth weight and blood pressure in children, adolescents and adults. The most persistent findings have been observed in children with a history of low birth weight or intrauterine growth restriction, while a large number of studies carried out in populations with normally distributed birth weight have shown conflicting results. A recently reported strong direct association between high birth weight and blood pressure, and the significant positive effect of postnatal growth on blood pressure suggests that the fetal origins of adult disease hypothesis should be expanded to include the role of excessive fetal and postnatal growth. In this paper, we review recent studies on the relationship between birth weight and blood pressure in childhood, with a focus on confounding variables that may explain the conflicting results of published work in this field. 相似文献

Biological clocks and the digestive system 总被引:4,自引:0,他引:4
Scheving LA 《Gastroenterology》2000,119(2):536-549
Circadian rhythms play a major role in regulating the digestive systems of many organisms. Cell proliferation, migration, differentiation, and even structure vary as a function of time of day in many different digestive organs (i.e., stomach, gut, liver, and pancreas) and cell types, resulting in regionally specific temporal variations in protein and gene expression. Feeding and light set the hands of the digestive clock(s). However, the clockwork has a genetic basis. During the last 10 years, new developments have emerged in our understanding of how cells keep time. Surprisingly, clock genes in mammals are expressed not only in specialized time keepers in the brain, but also in peripheral organs, suggesting that the ability to keep time may also belong to cells within the digestive system. This article reviews several classic examples of circadian variation in the digestive system, with an emphasis on rhythms in cell proliferation, function, and structure. It also briefly summarizes several new ideas about how cells in the brain and possibly the digestive system keep time. 相似文献

We have herewith examined the characteristics of circadian rhythms in patients with lepromatous leprosy, active or inactive, allowing a comparison with corresponding properties of rhythms in healthy subjects mapped earlier. Group results were illustrated by cosinor plots, produced directly on microfilm by computer. Eventually such reference standards in the form of cosinors, among other displays, notably of waveform, may be individualized and carried on a person's health record. Such a quantitative assessment of an individual's rhythms in health may serve for rigorous comparison with any changes accompanying increased susceptibility or occult or overt disease. 相似文献

AIMS: This paper reports a study examining the process and outcomes of a long-term, multicomponent smoking cessation intervention for patients with lung disease initiated while hospitalized and provided over 1-year postdischarge. BACKGROUND: Successful smoking cessation interventions are of primary importance for people with lung disease. Initiation of such an intervention in hospital settings is particularly important as patients may be especially motivated to quit as a result of strong perceptions of vulnerability while hospitalized for a smoking-related disease. Tailoring the intervention to each person's needs is a promising approach to practice. METHODS: All patients who smoked and were admitted to a pulmonary unit over 2 years were invited to participate in this quasi-experimental study (n = 85), and 69 continued beyond the first month. The intervention was shaped by the TransTheoretical Model and used nicotine replacement therapy, along with individual and group counselling and support grounded in the nurse-patient relationship. The intervention was provided during hospitalization and by telephone after discharge at 1 week, and 1, 3, 6 and 12 months. RESULTS: At 12-months postdischarge, 39% of the patients reported continuous abstinence from smoking from the time they joined the programme and 52% were not smoking at that time. No relationship was found between abstinence and the number of quit attempts, readiness to quit, nicotine dependency and length of hospital stay. Readiness to quit had increased and nicotine dependency decreased significantly by the end of the programme. No gender differences were found for the main variables. CONCLUSIONS: Comprehensive, individualized smoking cessation interventions for hospitalized patients having lung disease, with a 1-year follow-up, was successful. Abstinence was high in comparison with other studies. This may in part be explained by significantly enhanced motivation to quit during the smoking cessation programme. 相似文献
