Patients' desire for information about anaesthesia: Danish attitudes

Background : Patients' desire for information about anaesthesia has been examined in a number of Commonwealth countries but not in Scandinavia. A questionnaire was distributed to form a basis for giving Danish patients more appropriate preoperative information.
Methods : 201 preoperative patients in Denmark were asked to complete a questionnaire. The patients were divided into subgroups according to: age, gender, residential origin, ASA group, educational level, type of anaesthesia planned and number of previous anaesthetics.
Results : Patients from a city area required significantly more information than patients from a rural/urban area about pre-medication drugs, drips/catheters, pain/pain relief and complications. Men more than women preferred to know about dangerous complications. Information about pain /pain relief, duration of anaesthesia, and influence of anaesthesia on daily activities such as eating, drinking, mobilisation was given the highest priority, while unpleasant information such as about complications and needles was given the lowest priority. Meeting the anaesthetist and information about alternative methods of anaesthesia and premedication drugs were given only moderate priority. Ranking information in Denmark was significantly correlated with Scotland, Canada and Australia, despite profound differences in priority. More often than Danish patients, Australian patients felt they had right to know, and especially about complications.
Conclusion : Patients from a city area required more information than patients from a rural/urban area. Information about the influence on daily activities was preferred to unpleasant information. Ranking information in Denmark was correlated with a number of Commonwealth countries.     

机体阴阳交感现象的熵变分析

借用非平衡热力学理论,分析自然界水火运动的规律,得出结论——阴阳交感过程是熵减少过程,阴阳反作过程是熵增加过程;机体的许多阴阳变化也遵循同一规律。并在此基础上论证了新陈代谢过程是机体从外界输入负熵以抵消体内正熵产生的过程,从而推知阴阳交感现象发生的原因是新陈代谢。

来流温度不均匀对叉流换热器性能的影响

对来流温度不均匀叉流换热器,本文进行了熵产生和(火用)效率的数值分析。结果表明:①在相同的传热单元数和热容量比值下,对应于换热效果最好的来流温度分布,其熵产生单元数最小,(火用)效率最高。②在给定的条件下,换热器的(火用)效率并不是随传热单元数的增加而单调增加,而是存在一个极大值,它所对应的传热单元数要小于有效度ε_(max)对应的传热单元数。③熵产生单元数也并不是随传热单元数的增加而单调减少,而是有时单调增加,有时有极大值。并对以上现象作了一些物理机理的分析和讨论。     

Using online databases to find peer-reviewed journal articles on injury prevention and safety promotion research: a study of textword queries by SafetyLit users.

OBJECTIVE: To assess the capacity of textword queries to provide a comprehensive listing of articles on injury prevention and safety promotion (IPSP) concepts in a literature database. METHODS: All terms used to search SafetyLit (a database of scholarly literature selected for its relevance to the IPSP field) during the years 2000-2005 were listed and then examined to identify terms that are synonyms for the same concept. Terms were grouped by concept, the number of queries that used terms within each concept category were summed, and the concepts were then ordered by the total number of searches for each concept category. For each textword, the proportion of all articles for that concept that could be found by using it alone was calculated. RESULTS: Each of the 25 most searched-for concepts has 4 to 40 synonyms. Sixteen of the concepts required queries using two or more terms to find 75% of the available articles. Few searchers used a sufficient number of textword synonyms in their queries to return a complete listing of the available material. CONCLUSION: On the basis of this study, queries using only one or two textword terms are insufficiently sensitive to find all relevant journal articles about an IPSP concept.

糖尿病肾病患者血清TRPM7、Sirtuin-1与钙磷代谢、颈动脉钙化的相关性

目的 探讨糖尿病肾病（DN）患者血清瞬时受体电位通道7(TRPM7)、沉默调节蛋白-1(Sirtuin-1)与钙磷代谢、颈动脉钙化的相关性。方法 选取2020年12月—2022年11月成都大学附属医院收治的97例DN患者作为DN组,另取同期在该院就诊的120例2型糖尿病患者作为对照组。采用实时荧光定量聚合酶链反应检测血清TRPM7的表达,酶联免疫吸附试验检测血清Sirtuin-1水平。采用Pearson法分析DN患者血清TRPM7、Sirtuin-1水平与钙磷代谢的相关性,并通过多因素Logistic逐步回归模型分析DN患者颈动脉钙化的危险因素。结果 DN组血肌酐、尿素氮、血清TRPM7、血磷、颈动脉钙化率高于对照组（P <0.05）。DN组Sirtuin-1、血钙低于对照组（P <0.05）。Pearson相关性分析结果显示,DN患者血清TRPM7与血钙呈负相关（r=-0.247,P=0.000）,与血磷呈正相关（r=0.415,P=0.000）;DN患者血清Sirtuin-1与血钙呈正相关（r=0.367,P=0.000）,与血磷呈负相关（r=-0.505,P=0.00...     

Clinical information technology in hospitals: a comparison between the state of Iowa and two provinces in Canada

Despite the growing interest in adopting information technology (IT) in healthcare, the degree of technology sophistication varies among healthcare organizations. Changes in the health care sector and continuous pressure to improve the quality of care have driven the evolution of IT in hospitals. This paper provides an overview of clinical IT sophistication in a sample of U.S. hospitals, and compares clinical IT capacities in this sample with a sample of Canadian hospitals. The instrument used for the comparison measures three clinical dimensions of IT sophistication: functional sophistication, technological sophistication and integration level. Clinical areas that were considered include patient management, patient care activities and clinical support activities. The comparison between hospitals in Iowa and Canada shows differences in clinical IT sophistication between the two settings. Hospitals in Iowa appear to have more technologies but fewer computerized processes and integration of patient management activities. Technological sophistication however, was low in both samples. Our findings confirm the construct validity of the measurement instrument and show initial evidence of its generalizability. More initiatives using the instrument would lead to enhancement in IT assessment tools that can be used for evaluation of IT in relation to patient management and quality outcomes.     

On the role of static and dynamic visual afferent information in goal-directed aiming movements

Movement planning has been shown to be optimized when the participant is permitted to see his or her hand resting on the starting base prior to movement initiation. However, this proposition is opposed by contradictory results. In the present study, we wanted to determine whether these conflicting results were caused by procedural differences. The results showed that seeing one's hand on the starting base did not result in more accurate aiming movement than when this information was not available. However, lower aiming errors were found when one was asked to foveate the starting base and then the target prior to movement initiation, but only when no dynamic visual information was available during movement. When an aiming movement was performed while one's hand was visible in visual periphery, foveating the starting base or not prior to movement initiation did not modify aiming accuracy. These results suggest that gazing at the starting base and then at the target provides an eye-based representation of the movement to be performed that can be used by the CNS to plan a manual aiming movement. Information for better planning of the direction – but not the extent – dimension of an upcoming movement can also be derived from dynamic visual information available in peripheral vision.
