Objective:To examine the burden of caregivers for elderly Parkinson's patients(PD)and to analyze the mediating effects of social support on primary PD caregivers' burden and their quality of life.Methods:In this cross-sectional study, 281 primary caregivers for elderly Parkinson's patients who visited the Department of Neurology's outpatient clinics of Qilu Hospital of Shandong University from January to May 2021 were surveyed via a convenience sampling method, with 242 valid questionnaires(86.1%). The Chinese versions of the Caregiver Burden Questionnaire, Social Support Rating Scale and 36-Item Short Form Health Survey were used for the investigation.Pearson correlation analysis was used to establish a structural equation model for the influence of social support in the burden and quality of life of caregivers for PD patients.The mediating effects were tested using Process v2.16.3 and re-tested using AMOS.The mediating effects were validated with Bootstrap.Results:Primary caregivers' scores on burden, social support and quality of life were(26.9±23.1), (40.5±8.7)and(593.7±163.3), respectively.Caregiver burden was negatively correlated with social support(r=-0.482, P<0.01), and social support was positively correlated with quality of life(r=0.513, P<0.01). Caregiver burden was negatively correlated with quality of life( r=-0.654, P<0.01), The validated mediating effects showed caregiver burden's direct effects on quality of life(95% CI: -0.38-0.61)and mediating effects of social support(95% CI: -0.08-0.21), not including 0, indicating that the care burden of primary caregivers for elderly PD patients was not only able to predict their quality of life, but also predict their quality of life through the mediating effects of social support(direct effect: -0.50 and mediating effect: -0.14, accounting for 78.0% and 22.0%, respectively, of the total effect of -0.64). Conclusions:Care burden and social support are important factors affecting the quality of life of primary caregivers for elderly PD patients.Reducing care burden can not only directly affect the quality of life, but also indirectly affect the quality of life by increasing social support.

Objective:To discuss the feasibility of using online and offline combined multidisciplinary team (MDT) diagnosis-treatment mode in cancers diagnosis and treatment by comparing the comprehensive diagnosis and treatment plans formulated by online and offline MDT diagnosis-treatment mode.Methods:A total of 168 esophageal cancer patients collected from March 17, 2020 to May 17, 2020 were took as the research objects in Shandong Cancer Hospital and Institute, through whom the consistency of the comprehensive diagnosis and treatment plans formulated by online and offline MDT diagnosis-treatment mode was evaluated. The clinical characteristics of patients with changed comprehensive diagnosis and treatment plans, such as age, Karnofsky performance status (KPS) score, whether combined with basic diseases, whether received anti-tumor treatment before and tumor location were analyzed, so as to explore the mechanism to improve the efficiency on the basis of quality assurance.Results:The results showed that 86.3% (145/168) of the comprehensive diagnosis and treatment plans obtained by offline MDT diagnosis-treatment mode were consistent with online diagnosis-treatment MDT mode. Cases with inconsistent comprehensive diagnosis and treatment plans were characterized by elderly (> 69 years) ( χ2=4.250, P=0.039), KPS score≥80 ( χ2=15.520, P<0.001) and combined with underlying disease ( χ2=7.135, P=0.008). Through further analysis, the changed cases were also characterized as with inadequate auxiliary examination or complex in imaging. Conclusion:The online and offline combined MDT diagnosis-treatment mode is feasible. For the patients characterized of elderly (> 69 years old), KPS score ≥80, combined with underlying diseases, with incomplete auxiliary examination or complex in imaging, the offline MDT diagnosis-treatment mode should be adopted or supplemented.

Objective:To investigate the similarities and differences of Doppler echocardiographic parameters in healthy adults among Chinese (EMINCA study), Japanese (JAMP study) and Europeans (NORRE study).Methods:Based on the published Doppler echocardiographic data of JAMP and NORRE studies, the corresponding Doppler parameters were selected from the original database of EMINCA study and stratified by sex and age groups accordingly. Independent-samples t-test, summary t-test, and one-way analysis of variance (ANOVA) were used to test the differences between groups. Results:①Common Doppler parameters in three studies included: peak velocities of early diastolic (E) and late diastolic waves (A) of mitral valve inflow, E/A ratio, deceleration time (DT) of E wave, tissue velocities of early diastole (e′ ) and late diastole (a′ ) at both septal and lateral sites of the mitral annulus and the average value of e′ at both sites (average-e′), ratios of E to septal e′ (septal-E/e′), E to lateral e′ (lateral-E/e′), and E to average e′ (average-E/e′). ②Differences between genders: There existed significant gender differences for 5/10 of parameters in EMINCA study, 8/10 in JAMP study and 3/12 in NORRE study (all P<0.05). ③Stratification by sex and age groups: Except for DT for men in EMINCA study, significant differences were found in all 12 Doppler parameters both for men and women in all three studies (all P<0.05). ④Comparison between EMINCA and JAMP studies: There were statistically significant differences in 8/10 and 9/10 of parameters for men and women, respectively (all P<0.05). ⑤Comparison between EMINCA and NORRE studies: 7/12 of parameters both in men and women were significantly different between the two studies (all P<0.05). ⑥For the three studies, 6/10 of parameters both in men and women correlated positively with age ( r=0.12-0.66, all P<0.001), while 4/10 correlated negatively with age ( r=-0.27--0.72, all P<0.001). Conclusions:Doppler echocardiographic measurements in healthy adults are significantly different with genders, ages and races/nationalities. Therefore, gender, age and race/nationality-specific reference values of Doppler echocardiography parameters should be encouraged in clinical practice.
