This study aimed to systematically assess the readiness of five countries – Brazil, the Former Yugoslav Republic of Macedonia, Malaysia, Saudi Arabia, and South Africa – to implement evidence-based child maltreatment prevention programs on a large scale. To this end, it applied a recently developed method called Readiness Assessment for the Prevention of Child Maltreatment based on two parallel 100-item instruments. The first measures the knowledge, attitudes, and beliefs concerning child maltreatment prevention of key informants; the second, completed by child maltreatment prevention experts using all available data in the country, produces a more objective assessment readiness. The instruments cover all of the main aspects of readiness including, for instance, availability of scientific data on the problem, legislation and policies, will to address the problem, and material resources. Key informant scores ranged from 31.2 (Brazil) to 45.8/100 (the Former Yugoslav Republic of Macedonia) and expert scores, from 35.2 (Brazil) to 56/100 (Malaysia). Major gaps identified in almost all countries included a lack of professionals with the skills, knowledge, and expertise to implement evidence-based child maltreatment programs and of institutions to train them; inadequate funding, infrastructure, and equipment; extreme rarity of outcome evaluations of prevention programs; and lack of national prevalence surveys of child maltreatment. In sum, the five countries are in a low to moderate state of readiness to implement evidence-based child maltreatment prevention programs on a large scale. Such an assessment of readiness – the first of its kind – allows gaps to be identified and then addressed to increase the likelihood of program success.  相似文献

为了客观把握目前我国体育用品出口的发展现状,准确预测未来我国体育用品出口的发展趋势。收集了2004年1月至2006年8月我国体育用品出口的月度数据,进行了时间序列分析,建立了体育用品月出口额的自回归求和移动平均模型(即ARIMA模型)。结果显示:模型ARIMA(0,1,2)(0,1,1)能较为准确地预测我国体育用品出口额的月度数据,模型的预测值与实际观测值非常接近,说明时间序列模型在我国体育用品出口状况预测中具有较好的应用价值。  相似文献

Introduction

Preanalytical errors still constitute the largest source of errors in laboratory work. Proper patient preparation and patient’s knowledge about a particular procedure affects its accuracy and reliability. We hypothesized that most of pregnant women are not well enough informed about the proper procedure for the OGTT. The aims of this study were to investigate: (i) how well pregnant women are informed about the OGTT; (ii) the most common way to inform pregnant women about OGTT and (iii) whether pregnant women’s level of knowledge about the OGTT differ regarding source of information.

Materials and methods

The anonymous questionnaire was conducted across the country in 23 Croatian primary and secondary healthcare centres. The questionnaire contained 9 questions on certain demographic data and familiarity with OGTT procedure. All 343 participants filled the questionnaire before the first blood draw.

Results

42% of the participants demonstrated high and 38% adequate level of knowledge about the OGTT procedure. Majority of participants were informed about the procedure by gynaecologist (56%). The level of knowledge differed among participants with different sources of information (P = 0.030). Further analysis showed that the level of knowledge was lower in pregnant women having received information from their gynaecologist compared to pregnant women who received information from the laboratory staff.

Conclusions

In general, pregnant women are familiar with OGTT procedure, main source of information about the OGTT procedure is their gynaecologist, but the level of knowledge was higher in women who received information about the OGTT procedure from the laboratory staff.Key words: preanalytical phase, oral glucose tolerance test, survey, patient education, gestational diabetes  相似文献

The paraoxonase gene family in humans includes three members: PON1, PON2 and PON3. The products of those three genes are the following enzymes: paraoxonase 1 (PON1), paraoxonase 2 (PON2) and paraoxonase 3 (PON3). PON1 is mainly associated with a high density lipoprotein (HDL). A small amount of this enzyme is also bound to very low-density lipoprotein (VLDL) and postprandial chylomicrons. PON1 possess organophosphatase, arylesterase and lactonase activity and it hydrolyzes many different substrates. It is also known that PON1 may have antiatherogenic function. Compared to the PON1, PON2 and PON3 are much less studied and described. PON2 is ubiquitously expressed intracellular protein, while PON3 is bound to HDL, like PON1. The both enzymes possess antioxidant properties.  相似文献

To meet the need of teaching swimming in deep pool, the study designed a set of teaching method, by which beginners cou1d learn breast stroke and swim up to 5O meters in deep water. The newly designed method put emphasis on intensified technical drill on land and aJso included simplified procedure of getting familar with the characteristics of water, improved sequence of coordination, use of floats as aids, and adoptation of collective teaching form. The method has been proved to be safe, more effective with less teaching hours and uniform progreess, and consistent to the mental and physiological characteristics of beginners.  相似文献
