BackgroundThe complement system plays an important role in many neurological disorders.Complement modulation, including C3/C3a receptor signaling, shows promising therapeutic effects on cognition and neurodegeneration. Yet, the implications for this pathway in perioperative neurocognitive disorders (PND) are not well established. Here, we evaluated the possible role for C3/C3a receptor signaling after orthopedic surgery using an established mouse model of PND.MethodsA stabilized tibial fracture surgery was performed in adult male C57BL/6 mice under general anesthesia and analgesia to induce PND-like behavior. Complement activation was assessed in the hippocampus and choroid plexus. Changes in hippocampal neuroinflammation, synapse numbers, choroidal blood-cerebrospinal fluid barrier (BCSFB) integrity, and hippocampal-dependent memory function were evaluated after surgery and treatment with a C3a receptor blocker.ResultsC3 levels and C3a receptor expression were specifically increased in hippocampal astrocytes and microglia after surgery. Surgery-induced neuroinflammation and synapse loss in the hippocampus were attenuated by C3a receptor blockade. Choroidal BCSFB dysfunction occurred 1 day after surgery and was attenuated by C3a receptor blockade. Administration of exogenous C3a exacerbated cognitive decline after surgery, whereas C3a receptor blockade improved hippocampal-dependent memory function.ConclusionsOrthopedic surgery activates complement signaling. C3a receptor blockade may be therapeutically beneficial to attenuate neuroinflammation and PND.Electronic supplementary materialThe online version of this article (10.1186/s12974-018-1292-4) contains supplementary material, which is available to authorized users.
Background This study aims to analyse the current demand by senior citizens in Lanzhou, China for a combination of medical and elderly care services and to identify the factors influencing their needs. Methods 7500 participants aged 60 or above living in Lanzhou, China, were recruited, a unified questionnaire concerning elderly people’s demand for a service combining medical and elderly care has been adopted to survey these subjects. The status quo of the demand of the service combining medical and elderly care and its influencing factors were analysed with the single-factor Chi-square test and multi-factor binomial logistic regression method. Results 3772 of 7320 older people have the demand for the service combining medical and elderly care, accounting for 53.15% of survey respondents. Many factors are in play, including gender, marital status, degree of education, occupation before retirement, number of children, monthly income, health self-assessment status, endowment insurance type, medical insurance type, current nursing arrangements, old-age demands, self-care ability and the knowledge of combining medical and elderly care and the willingness to pay for the combination of medical and elderly care have statistical significance (P < 0.05) with the elderly’s needs, different ages, living styles and the prevalence of chronic diseases, have no statistical significance (P > 0.05) with the elderly’s care needs in Lanzhou. The number of children, type of medical insurance and willingness to pay for the combination of medical treatment and nursing care are major influencing factors among the complex factors influencing the elderly’s demand for the proposed service. Conclusions The low knowledge rate and demand rate, the number of children, the type of medical insurance, and the willingness to pay for the medical-nursing combination service for the elderly in Lanzhou have a great impact on the elderly’s demand rate for combining medical and elderly care. Meanwhile, relevant government departments should focus more on the promotion of the endowment model of combining medical and elderly care and provide integrated medical care services by integrating multiple resources, and improving social security.
Aim The goal of the study was to investigate the patterns of needs in older individuals with mild‐to‐moderate dementia living at home using the Camberwell Assessment of Need for the Elderly questionnaire. Methods This was a cross‐sectional study. A total of 378 home‐living residents served as the sample. The Camberwell Assessment of Need for the Elderly questionnaire was used to analyze the needs of those receiving adequate interventions (met needs) and those without appropriate supports (unmet needs). Thereafter, the factors that correlated with total needs were determined using demographic characteristics. Results Persons with dementia (PWD) had a mean care needs of 18.5 ± 5.4 (range 5–35). Unmet needs were most common in caring for someone (65.1%), looking after the home (63.5%), self‐care (58.7%) and intimate relationships (44.4%) domains. Higher needs were significantly related to living with others than a spouse, longer length of diagnosis, older age and higher cognitive function. Conclusion Unmet needs are common in home‐living PWD. Home‐based dementia care can identify and address PWD's unmet needs by focusing on care recipients and caregivers to enable PWD to remain safely at home and improve their quality of life.

Background: The ongoing coronavirus disease (COVID-19) outbreak has placed the healthcare system and student training under considerable pressure. However, the plights of healthcare students in the COVID-19 period have drawn limited attention in China.Methods: A cross-sectional on-line survey was undertaken between January and March 2020 to explore the COVID-19 knowledge, attitude, and practice (KAP) survey among Chinese healthcare students. Demographic information and data on KAP were obtained using a self-reported questionnaire. The percentage KAP scores were categorized as good or poor. Independent predictors of good knowledge of COVID-19 were ascertained to use a logistic regression model.Results: Of the 1,595 participants, 85.9% (1,370) were women, 53.4% were junior college students, 65.8% majoring in nursing, and 29.8% had received training on COVID-19. The overall median percentage for good KAP was 51.6% with knowledge of 28.3%, attitude 67.8%, and practice 58.6%, respectively. Independent predictors of good knowledge of COVID-19 were being students ≥25 (95% CI = 0.27–0.93, P = 0.02), those taking bachelor degrees (95% CI = 1.17–2.07, P = 0.00), and those having participated in COVID-19 treatment training.Conclusions: The result of this study revealed suboptimal COVID-19-related KAP among healthcare students in China. To effectively control future outbreaks of COVID-19, there is a need to implement public sensitization programs to improve the understanding of COVID-19 and address COVID-19-related myths and misconceptions, especially among healthcare students.
Background: With the spread of COVID-19 around the world, herd immunity through vaccination became a key measure to control the pandemic, but high uptake of vaccine is not guaranteed. Moreover, the actual acceptance of COVID-19 vaccination and associated factors remain uncertain among health care students in Northwest China.Methods: A cross-sectional survey of a sample of 631 health care students was performed using a questionnaire developed through Wen Juan Xing survey platform to collect information regarding their attitudes, beliefs, and acceptance of COVID-19 vaccination. Binary logistic regression analyses were performed to identify the association between vaccination willingness and demographics, attitudes, and beliefs to determine the factors that actually effect acceptance and hesitancy of COVID-19 vaccine among health care students.Results: Overall, 491 (77.81%) students actually received the COVID-19 vaccine, and of the 140 unvaccinated, 69 were hesitant and 71 rejected. Binary logistic regression analysis showed that the actually vaccinated individuals were those who mostly believed in the effectiveness of the COVID-19 vaccine (OR = 2.94, 95%CI: 1.37, 6.29), those who mostly felt it is their responsibility to receive the vaccine to protect others from infection (OR = 2.75, 95%CI: 1.45, 5.23), with less previous experience about other vaccines (OR = 1.70, 95%CI: 1.06, 2.72), students who mostly thought COVID-19 to be very severe (OR = 1.77, 95%CI: 1.07, 2.93), and students who mostly thought the COVID-19 vaccine was one of the best protection measures (OR = 1.68, 95%CI: 1.03, 2.76). Concerns about side effects of vaccines (OR = 0.30, 95%CI: 0.18, 0.51) and the use of personal protective behavior as an alternative to the COVID-19 vaccination (OR = 0.16, 95%CI: 0.06, 0.39) hindered the vaccine acceptance.Conclusions: Our study showed higher COVID-19 vaccine acceptance among healthcare students. However, the individuals with vaccine hesitancy and rejection were still worrying. Vaccine safety and effectiveness issues continue to be a major factor affecting students' acceptance. To expand vaccine coverage in response to the COVID-19 pandemic, appropriate vaccination strategies and immunization programs are essential, especially for those with negative attitudes and beliefs.
BackgroundVentilator-associated pneumonia (VAP) is defined as the occurrence of pneumonia in patients receiving mechanical ventilation for more than 48 h after endotracheal intubation. The implementation of effective oral care with antiseptics may reduce the incidence of ventilator-associated pneumonia. However, previous studies have been unclear about the best antiseptic for this purpose. Therefore, present protocol proposed to perform a network meta-analysis to evaluate the efficacy of different antiseptics to prevent ventilator-associated pneumonia.Methods/designWe will search CNKI, WanFang database, PubMed, Web of Science, Cochrane Library, EMBASE, SinoMed from their inception to March 2016. There are no restrictions on language, publication year, or publication type. Only randomized clinical trials (RCTs) with antiseptics to prevent ventilator-associated pneumonia will be considered. Study selection and data collection will be independently performed by two reviewers. Risk of bias assessments will be completed using the Cochrane risk of bias scale. The primary outcome is VAP morbidity. A network meta-analysis will be conducted to compare the effect of four different antiseptics on patient-relevant efficacy. Subgroup analyses will be performed by the type of setting and length of mechanical ventilation, and sensitivity analyses will be conducted to assess the robustness of the findings.DiscussionOral care to prevent ventilator-associated pneumonia has been widely used. The efficacy of usual oral antiseptics have been assessed mainly using traditional meta-analysis. However, it was unclear which oral care solution is best used for oral care and there were no head-to-head RCT to compare the efficacy of four antiseptics. The proposed network meta-analysis will compare four antiseptics and rank the results using network meta-analysis to decide which was the best.Systematic review registrationPROSPERO CRD42016038088 Electronic supplementary materialThe online version of this article (doi:10.1186/s13643-017-0496-5) contains supplementary material, which is available to authorized users.
ObjectivesThe aim of the study was to examine the level of patient satisfaction with nursing care and identify the factors affecting satisfaction from the inpatient’s perspective in a backward region of China.DesignThis was a cross-sectional study.SettingThe study was conducted at a tertiary hospital located in northwest China.ParticipantsPatients admitted to the ward for at least 48 hours were chosen to participate in the survey.Primary outcome measureThe Newcastle Satisfaction with Nursing Care Scale was used. Data were collected from 219 patients.ResultsThe overall inpatient satisfaction with nursing care was 78.15±4.74. Patients were more satisfied with nurses who respected their privacy and treated them as individuals (67.7%). Patients were least satisfied with the type of information nurses gave them (11.7%) and with the sufficient awareness of their needs. Patients who were married, had a history of hospitalisation, surgery and were taken charge of by junior nurses had higher satisfaction.ConclusionsThe overall level of patient satisfaction was moderate. Patient-centred individualised care and providing sufficient information model of care are needed. There was a need for nurses to be aware of patients’ individualised care needs and to provide them with more information. This study may suggest/urge hospital administrators, policymakers and nurses to be more sensitive with patients’ married status, history of hospitalisation and surgery, the professional title of in charged nurses when care is provided. Ultimately to achieve better outcome of patients’ hospitalisation.
