Parametric message passing-based relative navigation in joint tactical information distribution system

Relative navigation is a key feature in the joint tactical information distribution system（JTIDS）.A parametric message passing algorithm based on factor graph is proposed to perform relative navigation in JTIDS.First of all,the joint posterior distribution of all the terminals＇ positions is represented by factor graph.Because of the nonlinearity between the positions and time-of-arrival（TOA） measurement,messages cannot be obtained in closed forms by directly using the sum-product algorithm on factor graph.To this end,the Euclidean norm is approximated by Taylor expansion.Then,all the messages on the factor graph can be derived in Gaussian forms,which enables the terminals to transmit means and covariances.Finally,the impact of major error sources on the navigation performance are evaluated by Monte Carlo simulations,e.g.,range measurement noise,priors of position uncertainty and velocity noise.Results show that the proposed algorithm outperforms the extended Kalman filter and cooperative extended Kalman filter in both static and mobile scenarios of the JTIDS.

Depressive symptoms and associated factors among renal-transplant recipients in China

Aim:This study aimed to explore depressive symptoms and associated factors among renal-transplant(RT)recipients in China.Methods:This study included 287 RT recipients.Data were collected from August to November 2014 by utilizing demographic forms,namely,the Self-rating Depression Scale and the Multidimensional Scale of Perceived Social Support.Descriptive statistics,Student's t test,Chi-square test,ANOVA,and multiple linear regression were used for data analysis.Results:More than half of the recipients presented depressive symptoms.All recipients in the four transplant period groups(≤5 yr,5e10 yr,10e15 yr,and>15 yr)reported greater depressive symptoms than the Norm.No significant difference was observed in the depressive symptoms in the four transplant period groups.Multiple linear regression indicated that depressive symptoms were significantly associated with employment status,economic burden,inhabitation area,and social support.Conclusion:Depression is common among RT recipients in China.Employment status,economic burden,inhabitation area,and social support are the main factors affecting depression among RT recipients.Follow-up clinics should prescribe the evaluation of depression as a routine examination for RT patients.Moreover,depressed recipients must be provided with individualized care by collecting information on the depressive symptoms,employment status,economic burden,inhabitation area,and perceived social support of recipients.

Related factors of cognitive impairment after stroke

Moreover, we’d better pay attention to the control of all the risk factors of stroke, and improve the quality of life in stroke patients. OBJECTIVE: To analyze the factors that affect cognitive impairment after stroke. DESIGN: A related factors analysis. SETTINGS: Department of Neurology of Dalian Port Hospital and Dalian Second People’s Hospital. PARTICIPANTS: Totally 148 stroke inpatients were selected from Department of Neurology, Dalian Port Hospital and Dalian Second People’s Hospital from April 2004 to December 2005, including 100 males and 48 females, aging 45-75 years with an average age of (67±8) years; Their educational years ranged 2-10 years with an average of (6.1±3.7) years; The disease course ranged 15-30 days; All were right-handed. Inclusive criteria: All were accorded with the diagnostic standard set by the Fourth National Academic Meeting for Cerebrovascular Disease; Confirmed by CT or MRI; Informed consents were obtained from all the subjects. METHODS: After the disease conditions were stable, the patients were assessed with Wechsler memory scale (WMS) and Wisconsin card sorting test (WCST). WMS included forward and backward recitation of numbers and short-term memory (verbal memory, visual recognition). The number of times for correct and wrong classifications in WCST and the time to complete the trail making tests A and B were recorded. The focal volume, area and layer were recorded at 24 hours after admission. The general data of the patients were recorded, including name, sex, age, educational years, history of hypertension, history of diabetes mellitus. Electroencepalograph (EEG) was examined to record the wave shape, blood lipids were detected, and the cognition related indexes were analyzed with the Pearson correlation analysis. The correlation between cognitive indexes after stroke and the influencing factors were analyzed with multiple linear regression analysis. MAIN OUTCOME MEASURES: ① Correlation between cognitive indexes and imaging indexes; ② Influencing factors for cognitive indexes after stroke. RESULTS: All the 148 stroke patients were involved in the analysis of results. ① Correlation between cognitive indexes and CT indexes: There were obvious negative correlations between numerical symbol and focal layer (r =-0.234, P < 0.05), as well as between verbal memory and the focal area and volume (r =-0.363, -0.279, P < 0.05); Trail making test A had obvious positive correlation with focal area and volume (r =0.256, 0.256, P < 0.05). Results of multiple linear regression analysis: Correct classification was correlated with triglyceride (partial wave and θ wave (partial regression coefficient=0.231-0.908, P < 0.05); Verbal memory was correlated with EEG α wave, focal volume, sex, educational years and diabetes mellitus (partial regression coefficient=0.219-1.017, P < 0.05-0.01). Visual recognition had correlation with educational years and hypertension (partial regression coefficient=0.326, -1.163, P < 0.01). Trail making tests A and B were correlated with focal volume (partial regression coefficient=4.680, -18.561, P < 0.05). CONCLUSION: The factors that affect the cognitive function after stroke include sex, age, educational years, hypertension, diabetes mellitus, triglyceride, EEG wave shape, and the focal area, volume and layer.

Factors Relating to Nurses’ End-of-Life Care

Keywords identified were: “nurse” AND “end-of-life care” (“dyingcare” OR “‘deathcare”, OR “near end stage of life care” OR “palliative care” OR “hospice care” OR “comfortable care in near death” OR “quality of dying patients care”), AND “nurses”. The database searched through PubMed, ProQuest, Google Scholar, Web of Science and SCOPUS. The searching inclusion criteria were limited to English and Chinese language studies about nurses’ end-of-life care from 2010 to 2019, yielding 258 English language articles and 2Chinese language articles. Results: A total of fifteen articles were selected based on inclusion criteria. Two subjects were obtained from the results that related to nurses’ care during the process of end of life: 1) Nurses’ demographic factors;and 2) Modifiable factors. Nurses’ demographic factors were age, years of work experience, level of education and experience of the death of a family member/friend. Modifiable factors included knowledge, attitude, confidence, relationship, environment and resources, communication, nursing activities, philosophy and culture of care, skills and training. These factors were explored in various areas and majority of the studies had been conducted in public government hospitals. Conclusion: The major power ability of care was observed in nurses who acted the significant part in caring for the terminally ill during the dying process. Caring for dying patients was related to many factors which could affect the fabric of nursing care at the end stage of life. The elements found in this review could lead to recommendations with implications for nursing practice so as to improve and enhance end-of-life care. Some factors could be considered like predictors affecting nursing practice for chronical ill patients in further research. In addition, nurses’ tranquility care in community hospitals should be more focused.
