RESUMO
Background: Social Frailty is a significant public health concern affecting the elderly, particularly with the global population aging rapidly. Older adults with social frailty are at significantly higher risk of adverse outcomes such as disability, cognitive impairment, depression, and even death. In recent years, there have been more and more studies on social frailty, but no bibliometrics has been used to analyze and understand the general situation in this field. Therefore, by using CiteSpace, VOSviewer, and Bilioshiny software programs, this study aims to analyze the general situation of the research on social frailties of the older adults and determine the research trends and hot spots. Methods: A bibliometric analysis was conducted by searching relevant literature on the social frailty of the older adults from 2003 to 2022 in the Web of Science core database, using visualization software to map publication volume, country and author cooperation networks, keyword co-occurrences, and word emergence. Results: We analyzed 415 articles from 2003 to 2022. Brazil has the highest number of articles in the field of social frailty of the older adults, and the United States has the highest number of cooperative publications. Andrew MK, from Canada, is the most published and co-cited author, with primary research interests in geriatric assessment, epidemiology, and public health. "Social Vulnerability," "Health," "Frailty," "Mortality," and "Older Adult" are among the research hotspots in this field. "Dementia," "Alzheimer's disease," "Population," and "Covid-19" are emerging research trends in social frailty among the older adults. Conclusion: This scientometric study maps the research hotspots and trends for the past 20 years in social frailty among the older adults. Our findings will enable researchers to better understand trends in this field and find suitable directions and partners for future research.
RESUMO
Introduction: Ultrasound has become a routine method for endometrial receptivity (ER) evaluation. However, there is controversy over the independent evaluation values of various ultrasound indicators. Some researchers have designed multi-indicator prediction systems, but their prediction values are uneven. To further our understanding of ER, we conducted this prospective cohort study to estimate ER noninvasively and effectively. Methods: Women who underwent the first frozen-thawed embryo transfer (FET) cycle from April 2019 to July 2021 were included in the study. On the day of transfer, transvaginal three-dimensional ultrasound examination was performed to evaluate ER, including endometrial thickness, morphology, volume, movement, blood flow and flow index. The clinical pregnancy rate was the primary outcome. Based on whether clinical pregnancy was achieved, enrolled patients were divided into pregnant and nonpregnant groups. Results: This study analyzed 197 FET patients (139 pregnancies in total, 70.5%). The protective factors for clinical pregnancy included primary infertility [adjusted odds ratio (aOR), 1.98; 95% confidence interval (CI), 1.01-3.882; p = 0.047] and more frequent endometrial peristalsis (aOR, 1.33; 95% CI, 1.028-1.722; p = 0.03). Scores of 1-2 were assigned according to the relationship between different ultrasound indicators and the clinical pregnancy rate (CPR). The ER score of the patient was the sum of the scores of the 6 items. The ER score of the pregnant group was significantly higher than that of the nonpregnant group (7.40 ± 1.73 vs. 6.33 ± 1.99, p = 0.001). The CPR increased with an increasing ER score. The CPR in the ER < 6 group was significantly lower than that in the ER >6 group (45.5% vs. 75.6%, p = 0.001). Conclusion: A noninvasive ultrasound scoring system for ER was proposed. This system may provide a non-invasive guidance perspective, in conjunction with invasive assessments currently used in clinical practice, to achieve more effective embryo transfer.
RESUMO
OBJECTIVE: Pregnancy and childbirth bring not only joy but also a concomitant sense of insecurity, which may adversely affect health, role adaptation, and relationships. This study aimed to explore the risk factors for postpartum mothers' sense of security. METHODS: This cross-sectional study used questionnaires on Parents' Postnatal Sense of Security, Tilburg Pregnancy Distress Scale, and the Emotional Inhibition Scale. Structural equation modeling was used to calculate the mediating effect. RESULTS: The mean postnatal maternal security value was 44.77 ± 9.02. Multiple regression analyses revealed that several factors, including companionship of the partner during pregnancy, number of prenatal visits accompanied by the partner, complications during pregnancy, pregnancy distress, and emotional inhibition, independently predicted maternal security. Moreover, our structural equation model revealed that emotional inhibition significantly influenced maternal postpartum security directly (ß = -0.30, P < 0.001). In addition, pregnancy distress affected maternal security directly (ß = -0.45, P < 0.001) and indirectly (ß = -0.129, P < 0.001) through emotional inhibition. CONCLUSION: This study indicated a lower level of postpartum maternal sense of security. Emotional inhibition partially mediates the relationship between postpartum maternal sense of security and pregnancy distress. Therefore, health care professionals providing guidance to pregnant and postpartum women on proper emotional regulation and early identification of pregnancy distress may be more effective in enhancing their postpartum sense of security.
