Objective:To screen for preoperative frailty risk factors in elderly patients with spinal degenerative diseases and construct a risk prediction model.Methods:From September 2021 to August 2022, convenience sampling was used to select 324 elderly patients who underwent spinal surgery in the Department of Neurosurgery at Xuanwu Hospital, Capital Medical University as research subjects. The patients were surveyed using the General Information Questionnaire, Barthel Index, Nutritional Risk Screening 2002, Mini-mental State Examination, Geriatric Depression Scale-15, Generalized Anxiety Disorde-7, Athens Insomnia Scale, Charlson Comorbidity Index (CCI), and Modified Frailty Index. Binary Logistic regression analysis was used to explore the influencing factors of preoperative frailty in elderly patients with spinal degenerative diseases and establish a risk prediction model. Receiver Operating Characteristic (ROC) curve was used to assess the discriminative power of the model, and Hosmer-Lemeshow test was used to evaluate the goodness of fit of the model.Results:A total of 324 questionnaires were distributed, and 308 valid questionnaires were collected, with a valid response rate of 95.06% (308/324). Among 308 elderly patients with degenerative spinal diseases, 56 patients experienced preoperative frailty. Binary Logistic regression analysis showed that falls within one year, CCI, serum albumin, activities of daily living, and self-rated health status were the influencing factors for preoperative frailty in elderly patients with spinal degenerative diseases ( P<0.05). The area under the ROC curve of the prediction model was 0.851, with a sensitivity of 0.786 and a specificity of 0.778. Hosmer Lemeshow test indicated that the predictive model had a good fit (χ 2=3.764, P=0.709) . Conclusions:Falls within one year, CCI, serum albumin, activities of daily living, and self-rated health status are influencing factors for preoperative frailty in elderly patients with spinal degenerative diseases. The risk prediction model constructed can identify preoperative frailty early and has good predictive performance, which is worthy of clinical promotion.

Nurses play an important role in promoting asthma control. In order to improve the quality of nursing practice for adult asthma controlling, Registered Nurse' s Association of Ontario (RNAO) integrated the latest evidence and published the best practice guideline of Adult Asthma Care: Promoting Control of Asthma (Second Edition) in 2017. This article mainly introduces the development, application scope, main content, quality evaluation and subsidiary information of the guide.

Wechat has been widely used in nursing clinical clerkship teaching now. The application of Wechat in nursing clinical teaching mainly takes the form of Wechat group chat, Wechat public signal platform, Wechat friendship circle, online test and so on. Among them, Wechat group chat and Wechat public signal platform are used widely. Wechat enriches the teaching way, and improve the effectiveness of teaching, moreover, it facilitates the relationship between teachers and students. However, there are the ongoing challenges such as lacking of supervision and protection of intellectual property rights.

Postprandial hypotension is an abnormal regulation of blood pressure, which is common in the elderly. Due to insidious symptoms, postprandial hypotension is easily neglected by patients and medical staff in clinical practice, but it has a high degree of harm. There are many factors related to the occurrence of postprandial hypotension, including demographic factors, disease-related factors, lifestyle factors, postprandial postural factors and so on. Among demographic factors, age is positively associated with the occurrence of postprandial hypotension. Among disease-related factors, the existence of some basic diseases such as hypertension and diabetes, and the use of most kinds of anti-hypertensive drugs can increase the risk of postprandial hypotension. Among lifestyle factors, smoking is a risk factor for postprandial hypotension: while reducing the intake of staple foods, drinking large amounts of water or drinking green tea before meals may reduce the risk of postprandial hypotension. By taking different postures after meals, postural factors affect the rate of gastrointestinal emptying and then affect the occurrence of postprandial hypotension. Among the above factors, it is feasible to prevent postprandial hypotension by changing postprandial posture.

Gastrointestinal tract is the main site of human immunodeficiency virus (HIV) infection. Intestinal flora and its metabolites can affect the physicochemical properties, nutritional status and immune function of the intestinal tract. Improving the state of intestinal flora of AIDS patients can improve the immune function of patients and suppress the damage caused by HIV virus to the body. Moringa oleifera combined enteral nutrition can improve the intestinal microecology of AIDS patients and effectively improve the nutritional status of the patients, but there is the possibility of interaction with antiviral drugs, garlic, hypericum perforatum and other herbs. The microbial ecological agents have a weak regulation effect on the intestinal flora of AIDS patients, but it can improve the immune function of patients to a certain extent. Fecal microbiota transplantation does not significantly change the diversity of intestinal flora in AIDS patients, and the long-term complications are still to be clarified, but it can improve the immunity of patients to some extent. The preservation of microbial ecological agents, dietary regulation of intestinal flora and nursing after fecal microbiota transplantation in AIDS patients are still to be studied.

This paper reviews the contents, mechanism of action, operating principles and application effects of sensory stimulation program in the rehabilitation of critically ill neurologic patients with disorders of consciousness. It points out that the operating standards of sensory stimulation program need to be unified. In the future, more large-sample, multi-center randomized controlled studies of sensory stimulation program in the rehabilitation of critically ill neurologic patients with disorders of consciousness need to be carried out to provide a reference for clinical implementation of sensory stimulation program.

Nurses from all medical environments have close contacts with asthma patients, it can recognize the early indicators of poor asthma control, and provide self-management education and play important roles in the promotion of asthma control.
