IntroductionEssential hypertension is a major preventable risk factor for early cardiovascular disease, premature death and disability. It has been reported that telemedicine interventions can provide an innovative solution to essential hypertension to overcome the barriers that exist in traditional treatment or control. Nevertheless, this subject has not been thoroughly investigated. The goal of this study is to systematically evaluate and describe the impact of telemedicine interventions on essential hypertension.Methods and analysisTo find relevant research, we will conduct a systematic literature search of three databases (PubMed, Embase and Cochrane Library), with no language limitations, in addition to researching grey literature. Two reviewers will extract the data individually, and any disagreements will be resolved by discussion or by a third reviewer. The randomised controlled trials will be chosen based on predetermined inclusion criteria. Primary outcomes will include systolic blood pressure and diastolic blood pressure after the telemedicine intervention. Secondary outcomes will include medication adherence (eg, the Morisky Medication Adherence Questionnaire), quality of life (eg, the MOS item scale of the Health Survey Short Form 36 questionnaire), blood pressure control rate and adverse events (eg, stroke, chronic renal failure, aortic dissection, myocardial infarction and heart failure). The quality of the included studies will be assessed using the Cochrane risk-of-bias method. The data will be analysed using RevMan V.5.3.5 software and STATA V.16.0 software. If heterogeneity testing reveals little or no statistical heterogeneity, a fixed effect model will be used for data synthesis; otherwise, a random effect model would be employed. We will synthesise the available evidence to perform a high-quality meta-analysis.Ethics and disseminationThis project does not require ethical approval because it will be conducted using publicly available documents. The review’s findings will be published in peer-reviewed journals and publications.PROSPERO registration numberCRD42021293539.

Previous studies have shown that reflective learning and mind mapping have many advantages in nursing education, but the relevant researches on the joint application of the two strategies are very limited.To confirm the efficacy of reflective learning based on visual mind mapping for educational purposes to support the critical thinking, academic self-efficacy, and professional self-concept of nursing students.A quasi-experimental design with pretest and posttest model.A nursing college in Chengdu, Sichuan Province, China.Eighty 2nd year baccalaureate nursing students in two parallel classes were assigned to an intervention group (n = 40) and a control group (n = 40) with one class for each group.This study was carried out from September 15 to November 30, 2021. The Chinese version of Critical Thinking Disposition Inventory (CTDI-CV), the Chinese version of Academic Self-Efficacy Scale (ASE-CV), and the Chinese version of Professional Self-Concept of Nurses Instrument (PSCNI-CV) were used to evaluate the effects of the study intervention on nursing students. Firstly, the pretest data were collected from students in the two groups. Then, the intervention group students made regular reflective entries based on mind mapping and the control group students conducted traditional reflective journal, while attending routine educational and clinical activities, about their experiences of the Fundamentals of Nursing course learning process. After the intervention, both groups completed the three scale tests again, and an open-ended question was set for intervention group to explore the difficulties or challenges encountered by students. Descriptive statistics, Chi-square, Mann-Whitney U test, and content analysis were performed.There were no significant baseline demographic variables differences between the two groups. The intervention group showed significant improvement in critical thinking (P = 0.000), including truth-seeking, open-mindedness, analyticity, systematization, and inquisitiveness sub-dimensions (P = 0.000-0.014), and professional self-concept (P = 0.015), including flexibility and satisfaction sub-dimensions (P = 0.015-0.039), as compared to the baseline. There was no significant difference in students' academic self-efficacy level between pretest and posttest of the two groups. Compared to the total level of critical thinking between the intervention and the control group, the difference median values (posttest score-pretest score) were 14.0 and 1.5 respectively; and for professional self-concept, were 4.5 and 0.5 respectively, which were statistically significant at P 0.05 level (P = 0.001-0.020). According to open-ended question survey, difficulties or challenges faced by the intervention group students were mainly problem of charting mind mapping, unfamiliar with tools, problem of mentors' guidance, and time-consuming.This study found that it is appropriate for students to adopt reflective learning based on visual mind mapping. Although there were no significant differences in the improvement level of students' academic self-efficacy, students' critical thinking and professional self-concept were greatly improved by the intervention. This approach may be used as a complementary learning method for baccalaureate nursing education.

To examine the dyadic effects of rumination and self-disclosure on posttraumatic growth among newly diagnosed gynecological cancer couples.This cross-sectional study recruited 400 newly diagnosed gynecological cancer couples from a tertiary general hospital from July to December 2020. Questionnaires were administered to collect information on demographic and cancer-related characteristics, rumination, self-disclosure, and posttraumatic growth. The actor-partner interdependence model was used to explore the dyadic effects of rumination and self-disclosure on posttraumatic growth.Gynecological cancer survivors reported more posttraumatic growth than their spouses. The patients' deliberate rumination and self-disclosure and spouses' self-disclosure had actor and partner effects on their own and their spouses' posttraumatic growth. Besides, the patients' intrusive rumination and spouses' deliberate rumination had actor effects on their own posttraumatic growth.Spouses' posttraumatic growth was influenced by their own and their wives' deliberate rumination and self-disclosure, while survivors' posttraumatic growth was affected by their own deliberate rumination, intrusive rumination, self-disclosure, and their spouses' self-disclosure. Promoting deliberate rumination and self-disclosure could facilitate the couples' posttraumatic growth. Besides, reducing intrusive rumination may be useful for the survivors and indirectly contribute to spouses' posttraumatic growth. This study indicates that couple-centered interventions may be crucial and more effective in facilitating posttraumatic growth among newly diagnosed gynecological cancer couples.

To evaluate the effectiveness of preoperative shaving and postoperative shampooing on the infection rate in neurosurgery.Meta-analysis.We conducted a search of the Embase, CINAHL, Scopus and PubMed databases up until February 1, 2022. Comparative studies were included. No language restrictions were applied.Original articles that compared the infection rate of patients who had their hair shaved before neurosurgery to the infection rate of unshaven patients were included. Original articles comparing the infection rates of patients whose hair was early postoperative shampooing versus patients whose hair was not shampooed after neurosurgery were also included. The risk of bias was also evaluated using the Newcastle-Ottawa quality assessment scale by two authors independently. The meta-analyses were performed using Review Manager software (RevMan 5.3; Cochrane Collaboration). The odds ratios (ORs) and 95% confidence intervals (CIs) were assessed for dichotomous data (infection rate). The heterogeneity of the included studies was assessed using the IA total of 3451 studies were identified by searching the PubMed, Scopus, CINAHL and Embase databases. Fourteen studies met the inclusion criteria, however two studies did not provide data suitable for meta-analysis. Twelve studies were included in the review. Two historical control studies, four prospective studies, one clinical trial and five retrospective studies were identified. There were 4583 patients whose hair was not shaved and 4295 patients whose hair was shaved. Among them, there were 3874 patients whose hair was unshaved and was early postoperative shampooing. No significant difference in the infection rate was found between the unshaved group and shaved group (OR: 0.86, 95% CI [0.62, 1.19], P = 0.85, IHair preservation before neurosurgery and early shampooing after neurosurgery did not increase the infection rate.

High-speed dynamic balance is a main method to solve the problem of exceeding the aero engine vibration limit. However, with the development of techniques of high performance engine, the rotating speed of a rotor becomes more and more high, which turns into a challenge to balance it. Therefore, balancing the rotor with high speed effectively is very important. How effective the engine rotor of high speed dynamic balance is very important.

ObjectiveThe aim of this review was to systematically search and critique relevant literature on the potential psychological impact of earthquakes on peripartum women to synthesize existing knowledge for further action.MethodsA search through 5 databases was conducted for relevant publications in English, and the results were screened through a set of inclusion and exclusion processes.ResultsEight articles were included. Depression and posttraumatic stress disorder were the most often reported mental disorders. Some factors (eg, family relationships and social support) were associated with mental disorders suffered by peripartum women after earthquakes. An assessment of the quality of the studies showed that most did not have high levels of evidence because of their cross-sectional design and limitations.ConclusionsAmong the factors that influenced the mental health of pregnant and postpartum women after earthquakes, family function appears to be one of the most important and deserves further exploration. Other mental health conditions such as minor psychiatric disorders should also be studied for their relationship with disasters and pregnancy. Well-designed studies are needed to enable a better understanding of the relationship between earthquakes and the mental disorders of peripartum women so that the most appropriate interventions can be proposed.

To evaluate the effects of a hospital-community partnership transitional program among patients with coronary heart disease.This was a randomized controlled trial with 236 patients who were randomized into two groups. The patients in the control group received the usual care. In contrast, the patients in the study group received the transitional care program. The data were collected at the baseline, 30 days, and 90 days after discharge. The primary outcomes were the 30 and 90 day readmission rates after discharge. The secondary outcomes included the quality-of-care transitions, medicine adherence, and chronic disease self-efficacy.The findings indicated that: (i) the patients in the study group reported significantly lower 30 and 90 day readmission rates after their discharge than those in the control group; (ii) statistically significant differences were found in the quality-of-care transitions at 30 days postdischarge between the two groups as the patients in the study group reported significantly higher quality-of-care transitions, compared to those in the control group; and (iii) the patients in the study group reported significantly higher scores in medication adherence and chronic disease self-efficacy at 30 and 90 days after discharge than those in the control group.This study is an original effort to establish and evaluate a hospital-community partnership transitional care program in patients with coronary heart disease in China and the findings have demonstrated its effects.

The Wenchuan Earthquake that hit Sichuan, China in 2008 not only caused huge losses in terms of human life and economic damage. It also caused psychological trauma in survivors, especially those who had lost relatives and close friends (bereaved). In the aftermath of earthquakes, bereaved individuals require family and spiritual renewal in addition to material assistance.This study investigated the status of and relationship between family function and depression in bereaved individuals living in areas devastated by the Wenchuan Earthquake. Results provide baseline information for post-disaster family reconstruction.This cross-sectional study surveyed 264 qualified bereaved individuals who lived in an area hard hit by the Wenchuan Earthquake. Face-to-face interviews were administered based on the family APGAR(adaptation, partnership, growth, affection, resolve) index and Hamilton depression (HAMD) scale.The mean family function score for participants was 6.52 ± 2.65. Results for half (50.0%) of participants indicated "good" family function. Results indicated marital status, family structure and status of having another baby as factors that significantly influence family function (p.05). Participants' mean depression score was 40.41 ± 9.35, with all (100%) of participants demonstrating symptoms of depression. The 5 most prevalent depressive symptoms were: depressed mood, decreased interest in work, mental anxiety, diminished capacity and agitation. Results showed marital status, leisure frequency, economic status, and having another baby as factors that significantly influenced family function (p.05). A Pearson's correlation analysis indicated no significant relationship between level of depression and family function (p.05).Family functions of the bereaved living in areas hard hit by the Wenchuan Earthquake were all undermined to varying degrees. Although participants all exhibited depressive symptoms, this study found no affect of such symptoms on family functions. Interventions delivered in the months and years after an earthquake should be tailored to address each individual's depression status. Interventions should also help these individuals learn to improve and enhance family functions to effectively reduce negative behaviors and reactions in order to better promote physical and mental health.

To explore the efficacy and complication of bilateral multi-target radiofrequency lesion operation in patients with affective disorder.One hundred and eighty-two cases with affective disorder were treated with unstaged bilateral multi-target radiofrequency thermocoagulation. The efficacy was evaluated with the method established in 1990 by the National Psychosurgery Cooperative Group.After 2 weeks of operation, 86 cases with remarkable improvements, 81 cases with improvements, 15 case with no improvements, no case with progression, total efficient ratio was 91.76%. With 6-54 months of follow-up to all of 166 cases, 38 cases with recovery, 59 cases with remarkable improvements, 52 cases with improvements, 17 cases with no improvements, no case with progression, total efficient ratio was 89.76%. Except for early temporal complication of stereotaxic operation, the long-term complication ratio was less than 1%.CT-guided bilateral multi-target operation is prominent in treatment of affective disorder with high efficacy and safety.
