RESUMEN
Objective:To investigate the characteristics of cognitive frailty and its influencing factors in older patients with chronic heart failure.Methods:In this cross-sectional study, 300 older patients hospitalized for chronic heart failure in a tertiary hospital in Shandong Province between September 2021 and September 2022 were selected.A general information questionnaire, the mini-nutritional assessment scale-short form(MNA-SF), the athens insomnia scale(AIS), the ulca loneliness scale, the geriatric depression scale-5 item version(GDS-5), and the social support rating scale(SSRS)were used for assessment and influencing factors were identified by univariate and Logistic regression analysis.Results:Among 300 older patients with chronic heart failure, the prevalence of cognitive frailty was 75.3%(226 cases). Logistic regression analysis showed that age between 70-79 years( OR=0.543, 95% CI: 0.299-0.987), education level( OR=3.644, 95% CI: 1.780-7.461), weekly intellectual activity( OR=2.168, 95% CI: 1.082-4.334)and loneliness( OR=1.101, 95% CI: 1.032-1.175)were factors influencing cognitive frailty in older patients with chronic heart failure. Conclusions:The prevalence of cognitive frailty in older patients with chronic heart failure is high, and age, education level, weekly intellectual activity and loneliness are influencing factors, with education level having the greatest impact on older patients with chronic heart failure.
RESUMEN
Chinese jujube (Ziziphus jujuba Mill.), an economically significant species in the Rhamnaceae family, is a popular fruit tree in Asia. The sugar and acid concentrations in jujube are considerably higher than those in other plants. Due to the low kernel rate, it is extremely difficult to establish hybrid populations. Little is known about jujube evolution and domestication, particularly with regard to the role of the sugar and acid components of jujube. Therefore, we used cover net control as a hybridization technique for the cross-breeding of Ziziphus jujuba Mill and 'JMS2' and (Z. acido jujuba) 'Xing16' to obtain an F1 population (179 hybrid progeny). The sugar and acid levels in the F1 and parent fruit were determined by HPLC. The coefficient of variation ranged from 28.4 to 93.9%. The sucrose and quinic acid levels in the progeny were higher than those in the parents. The population showed continuous distributions with transgressive segregation on both sides. Analysis by the mixed major gene and polygene inheritance model was performed. It was found that glucose is controlled by one additive-dominant major gene and polygenes, malic acid is controlled by two additive-dominant major genes and polygenes, and oxalic acid and quinic acid are controlled by two additive-dominant-epistatic major genes and polygenes. The results of this study provide insights into the genetic predisposition and molecular mechanisms underlying the role of sugar acids in jujube fruit.
RESUMEN
Objective:To explore the mediating roles of family resilience and perceived social support between fear of progression and quality of life in patients with adult pulmonary hypertension, so as to provide guidance for grassroots medical staff to deeply understand and improve the long-term quality of life of adult pulmonary hypertension patients.Methods:Using a convenience sampling method, 219 adult pulmonary hypertension patients who attended Qilu Hospital, Shandong University from July 2021 to February 2022 were selected for a cross-sectional study using the World Health Organization Quality of Life Questionnaire Abbreviated Version (WHOQOL-BREF), Perceived Social Support Scale (PSSS), Shortened Chinese version of the Family Resilience Assessment Scale (FRAS-C) and Chinese version of Fear of Progression Questionnaire-Short Form (FoP-Q-SF) for investigation. A structural equation model was established to evaluate the mediating effect of family resilience and perceived social support on fear of progression and quality of life.Results:The scores of WHOQOL-BREF, PSSS, FRAS-C, and FoP-Q-SF were (45.85 ± 10.22), 66(56, 75), 94(89, 97) and 39(32, 46) points in adult pulmonary hypertension patients. The total scores of WHOQOL-BREF were negatively correlated with FoP-Q-SF ( r = -0.63, P<0.01), and positively correlated with FRAS-C and PSSS ( r=0.54, 0.46, both P<0.01). Family resilience played a partial mediating role between fear of progression and quality of life, accounting for 13.43% of the total effect. Family resilience and perceived social support played a chain mediating role between fear of progression and quality of life, accounting for 2.71% of the total effect. Conclusions:Family resilience-perceived social support play mediating roles between fear of progression and quality of life, healthcare workers can alleviate fear of progression and improve quality of life by promoting the levels of family resilience and perceived social support of adult pulmonary hypertension parents.
RESUMEN
Objective To investigate the effects of a multi-component exercise nursing intervention on frailty,activities of daily living and quality of life in elderly patients with chronic heart failure.Methods Through literature analysis and expert meeting,the multi-component exercise nursing intervention program was formed.A total of 71 elderly patients with chronic heart failure who admitted from January 2022 to September 2022 in a tertiary A hospital in Shandong Province were randomly divided into an intervention group(35 cases)and a control group(36 cases).The control group received usual care,while the intervention group received an additional multi-component exercise nursing training.2 groups were evaluated by Tilburg frailty indicator scale,modified Barthel index scale and 12-item short form health survey scale before the intervention,4 weeks and 12 weeks after the intervention.Results A total of 62 patients(31 in the experimental group and 31 in the control group)completed the study.Generalized estimation equation results showed that the inter-group effect,time effect and interaction effect of frailty,activities of daily living and quality of life in the 2 groups were statistically significant(P＜0.05).At 4 weeks and 12 weeks after the intervention,the Tilburg Frailty Indicator scale scores in the intervention group were lower than that in the control group(P＜0.05),and the scores of the modified Barthel index scale and 12-item short form health survey scale were significantly higher than those in the control group(P＜0.05).Conclusion The multi-component exercise nursing intervention can effectively improve frailty,activities of daily living and quality of life in elderly patients with chronic heart failure.
