BACKGROUND The risks associated with negative doctor-patient relationships have seriously hindered the healthy development of medical and healthcare and aroused wide-spread concern in society.The number of public comments on doctor-patient relationship risk events reflects the degree to which the public pays attention to such events.Thirty incidents of doctor-patient disputes were collected from Weibo and TikTok,and 3655 related comments were extracted.The number of comment sentiment words was extracted,and the comment sentiment value was calculated.The Kruskal-Wallis H test was used to compare differences between each variable group at different levels of incidence.Spearman’s correlation analysis was used to examine associations between variables.Regression analysis was used to explore factors influencing scores of comments on incidents.RESULTS The study results showed that public comments on media reports of doctor-patient disputes at all levels are mainly dominated by“good”and“disgust”emotional states.There was a significant difference in the comment scores and the number of partial emotion words between comments on varying levels of severity of doctor-patient disputes.The comment score was positively correlated with the number of emotion words related to positive,good,and happy)and negatively correlated with the number of emotion words related to negative,anger,disgust,fear,and sadness.CONCLUSION The number of emotion words related to negative,anger,disgust,fear,and sadness directly influences comment scores,and the severity of the incident level indirectly influences comment scores. 展开更多

Objective: To research the relationship between psychological stress and doctor-patient relationship of cancer patients and their families. Methods: The patients were randomly divided into the intervention group and the control group, and PDRQ-15, pcl-c, SAS and SDS scales were selected as evaluation indexes, and the levels of norepinephrine and dopamine were compared between the patients diagnosed with PTSD cancer and those without PTSD. Results: 1) The total score of PCL-C, SAS, SDS, PDRQ-15 scale of the cancer patients and their families after the intervention of clinical psychological care was significantly lower than that of before intervention and the control group. 2) The correlation coefficients between PCL-C, SAS, SDS and PDRQ-15 of cancer patients and their relatives were 0.971, 0.952 and 0.939 respectively. The significant test P value was less than 0.05 and the difference was statistically significant. 3) The plasma levels of dopamine and norepinephrine in cancer patients under stress were significantly higher than those in cancer patients without stress (P Conclusion: After psychological Intervention of cancer patients and their families, post-traumatic stress disorder, anxiety, depression and doctor-patient relationship were all improved. 展开更多

Introduction: spiritual anamnesis is fundamental to familiarity with patient’s beliefs. It enables health professionals to: investigate how patients face the treatment, understand the role and importance of religion in the life of this individual, how much spirituality may interfere in the health-disease process and in the disease experience. It also helps detect spiritual needs and mobilize resources to promote the biopsychosocial and spiritual wellness of the individual. Objective: identify spiritual questionnaires in literature. Methods: This article is a bibliographic review. Researching was on books and electronically based from August to December 2014. PUBMED and SCIELO databases were used in English and Portuguese. Inclusion factors: short, brief and easy to memorize questions to know if the patient’s beliefs interfere in medical treatments and to what extent. Exclusion factors: not try to convert or to interfere with the patient’s rights, not try to influence their beliefs or to make anamnesis on emergency situations or acute medical consultations. Results: based on the questions of seven samples of spiritual questionnaires found in literature, health professionals identified the patient’s spiritual needs and the beliefs likely to interfere in the doctor-patient relationship and in the therapeutic conduct as such. The anamnesis models found converge in some points, but differ mainly as to time excess some questionnaires demand (due to the large number of questions) when compared to others (shorter) and/or when going deeper into a particular aspect of beliefs, leaving some important points out. Conclusion: the anamnesis found are as follows: FICA Questionnaire; HOPE Questionnaire, Kunh’s Spiritual Inventory, CSI-MEMO, ACP Spiritual History, Matthews Spiritual History, Maugans Spiritual History. The main points found in these seven questionnaires are: resources mobilization to meet the patients’ spiritual demands; to what extent spirituality may interfere both in adherence to the treatment and in the clinical treatment and in strengthening the doctor-patient relationship. 展开更多

A correlation analysis of the individual station seasonal rainfall with all India seasonal mean rainfall has been made. After taking the significance test (strictly up to 5% level) the stations which are significantly correlated have been considered in this study in normal, flood and drought years respectively. Analysis of seasonal rainfall data of 50 stations spread over a period of 41 years suggests that a linear relationship fits better than the logarithmic relationship when seasonal rainfall versus number of rainy days is studied. The linear relationship is also found to be better in the case of seasonal rainfall versus mean daily intensity. 展开更多

The intensity of interannual variability(IIV)of the monsoon and monsoon–ENSO biennial relationship(MEBR)were examined and compared for both the Indian summer monsoon(ISM)and western North Pacific summer monsoon(WNPSM)during 1958–2018.Covariability of the IIV and MEBR were identified for the two monsoons.When the MEBR was strong(weak),the IIV of the monsoon was observed to be large(small).This rule applied to both the ISM and WNPSM.Out-ofphase relationships were found between the ISM and the WNPSM.When the IIV and MEBR of the ISM were strong(weak),those of the WNPSM tended to be weak(strong).During the period with a stronger(weaker)ENSO–Atlantic coupling after(before)the mid-1980 s,the IIV and MEBR of the WNPSM(ISM)were observed to be stronger.The increasing influences from the tropical Atlantic sea surface temperature(SST)may trigger the observed seesaw pattern of the ISM and WNPSM in terms of the IIV and MEBR multidecadal variability.The results imply that tropical Atlantic SST may need to be given more attention and consideration when predicting future monsoon variability of the ISM and WNPSM. 展开更多

For an anti-plane problem, the differential operator is self-adjoint and the corresponding eigenfunctions belong to the Hilbert space. The orthogonal property between eigenfunctions (or between the derivatives of eigenfunctions) of anti-plane problem is exploited. We developed for the first time two sets of radius-independent orthogonal integrals for extraction of stress intensity factors (SIFs), so any order SIF can be extracted based on a certain known solution of displacement (an analytic result or a numerical result). Many numerical examples based on the finite element method of lines (FEMOL) show that the present method is very powerful and efficient. 展开更多

Under the background of medical disputes growing in number,scale and intensity,tracing back legal changes in medical field as a breakthrough point,this paper took a legal perspective to illustrate changes in medical dispute settlements from legislative orientation to legal system improvement.In view of the fact that early legislation in medical field was biased towards identification and punishment of doctors’responsibility,and later intensive legislation in balancing increasing"medical trouble"phenomenon with limited effects and difficulties to abide by the law,this paper proposed to improve doctor-patient dispute settlements system in China referencing from foreign law experience,to reduce investigation of doctors at the judicial level,and to establish a settlement mechanism on doctors’apology at the legislative level,so as to promote a healthy development of doctor-patient relationship. 展开更多
