Preparing nursing summaries entails finding the required information in nursing records that span a long period of time and then concisely summarizing this information. This time consuming process depends on the clinical experience and writing ability of the nurse. The system described here automatically generates the text data needed for nursing summaries using an algorithm that synthesizes patient information recorded in electronic charts, the Nursing Care Plan information or the data entered for North American Nursing Diagnosis Association (NANDA) 13 domains with predetermined fixed phrases. Advantages of this system are that it enables nursing summaries to be generated automatically in real time, simplifies the process, and permits the standardization of useful nursing summaries that reflect the course of the nursing care provided and its evaluation. Use of this system to automatically generate nursing summaries will allow more nursing time to be devoted to patient care. The system is also useful because it enables nursing summaries that contain the required information to be generated regardless of who prepares them.展开更多

Analyzing the relationships among these elements to control and manage task-oriented dialogue systems is a challenging task. However, previous work has primarily focused on the independent recognition of user intent and emotion, making it difficult to simultaneously track both aspects in the dialogue tracking module and to effectively utilize user emotions in subsequent dialogue strategies. We propose a Multi-Head Encoder Shared Model (MESM) that dynamically integrates features from emotion and intent encoders through a feature fusioner. Addressing the scarcity of datasets containing both emotion and intent labels, we designed a multi-dataset learning approach enabling the model to generate dialogue summaries encompassing both user intent and emotion. Experiments conducted on the MultiWoZ and MELD datasets demonstrate that our model effectively captures user intent and emotion, achieving extremely competitive results in dialogue state tracking tasks.展开更多

Low and middle-income countries are the most affected. Diabetes self-management can significantly reduce the burden of diabetes complications and mortality. This cross-sectional study was conducted at the outpatient department of a county referral hospital in Kenya, from 1st August 2022 to 30th October 2022. Patients with known type II diabetes of age ≥ 20 years visiting the hospital for routine follow-up visits were included. A 7-tem Summary of Diabetes Self-care Activities (SDSAC) Questionnaire was used to assess Diabetes self-care activities. For data entry and statistical analysis, SPSS for Windows version 27.0 was used. There were 96 (39.2%) males and 149 (60.8%) females. Most of the participants were more than 61 years, 148 (60.4%). Significant association was found between the sum scale scores of dietary activities, blood glucose testing, physical activity, foot care, and neuropathy at 95% CI and (p Conclusions: Diabetes self-management activities have an impact on microvascular complications in patients with diabetes.展开更多

Focus has been put on different targets and diverse amount of bleeding of 3 Japanese bloodletting therapies, namely bloodletting puncture on Jing （Well）-Points, bloodletting puncture on collaterals and bloodletting puncture on skin. Meanwhile, a general comparison was made between the bloodletting therapy in Japan and the pricking blood therapy in China, which is expected to assist the progress of bloodletting therapy.展开更多

The prevalence of CVDs is continuously increasing in China and will remain an upward trend in the next 10 years. CVDs are the leading cause of death for Chinese in both urban area and rural area. Nowadays, 41.09% of deaths in rural area and 42.52% of deaths in urban area are caused by CVDs in China. The burden of CVDs remains heavy and has become an important public health problem. Effective strategies should be enforced urgently for the prevention of CVDs under the supervision of the government.
