RESUMO
PURPOSE: To analyze the ultrasound characteristics, clinical management, and pregnancy outcomes of heterotopic intramural pregnancies (HIMPs) after embryo transfer. METHODS: This was a retrospective observational study of women who were diagnosed with HIMPs. The ultrasound characteristics, clinical treatment, and pregnancy outcomes of patients with HIMPs were evaluated. RESULTS: Eight women with HIMPs were included. Among them, 6 patients were diagnosed by transvaginal sonography, and 2 patients were misdiagnosed with heterotopic interstitial pregnancy. The diagnostic accuracy was 75% (6/8). Five patients with HIMPs were diagnosed at the time of the initial scan (5+6-6+3 weeks). An intramural gestational sac was observed in all 6 patients, and an embryo with cardiac activity was detected in one patient on the follow-up scans. Intrauterine pregnancies (IUPs) were revealed in all 6 patients, and embryo(s) with cardiac activity were observed in 5 patients at the time of the initial diagnosis or later. The patients receiving expectant treatment all presented with bagel signs, while patients with embryos with cardiac activity all underwent surgery. Among the 6 diagnosed women, 1 patient was initially treated medically, 4 were treated expectantly, and 1 was treated surgically. Among the 6 diagnosed patients, the IUPs of 5 patients resulted in live infants. CONCLUSION: Single ET should be recommended to decrease the possibility of HIMP. An accurate diagnosis of HIMP was reached in most cases by detailed ultrasound early in the first trimester. Most IUPs of HIMPs seem to have good outcomes with timely and proper management. Expectant management might be a possible choice for nonviable intramural pregnancies.
RESUMO
Background: Cesarean scar pregnancy (CSP) is one of the rarest ectopic pregnancies which may be associated with life-threatening complications. Owing to the rarity of CSP, little is known about it. This study aimed to evaluate the value of the first-trimester transvaginal sonography (TVS) diagnosis and the risk factors of CSP after in vitro fertilization-embryo transfer (IVF-ET). Methods: This was a retrospective study of women undergoing IVF-ET between January 2013 and December 2018. Women who were diagnosed with a CSP using TVS and confirmed by surgery and histological examination were included. The clinical data and ultrasound findings were collected and analyzed. Univariate and multivariate logistic regression analyses were performed for evaluation of possible influence factors. Diagnostic parameters including sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of TVS were calculated for the diagnosis of CSP. Results: Overall, 75,438 consecutive women who underwent IVF-ET had received TVS during this period. Of these, 4,817 women (6.4%) had a history of cesarean section and 83 cases were found to have a CSP. Due to the absence of histological data, 19 cases treated conservatively were excluded. Finally, 64 cases were included, among whom 63 cases were correctly diagnosed [including 17 cases of heterotopic CSP (HCSP)] and 1 case was missed using TVS. Another 1 case of inevitable miscarriage was misdiagnosed as a CSP. The maternal age at the initial scan [34.0 (range, 26.0-44.0) years], the infertility duration [4.0 (range, 1-12) years], and the initial diagnostic time after ET [27 (range, 20-50) days] were recorded. A gestational sac (GS) was observed in all 63 cases during ultrasound examinations, including 28 with fetal pole, 25 with a yolk sac only, and 10 with an empty sac. The sensitivity and specificity of first-trimester TVS in diagnosing CSP were 98.44% and 99.98%, respectively; the PPV and NPV were 98.44% and 99.98%, respectively. Multivariate logistic regression analysis showed thinner endometrial thickness (ET) on transfer day [adjusted odds ratio (aOR): 0.83; 95% confidence interval (CI): 0.76-0.93, P<0.001] and multiple ET (aOR 53.60, 95% CI: 5.31-1,736.00, P=0.008) were independent risk factors for CSP and HCSP, respectively. Conclusions: First-trimester TVS performed by an experienced sonographer has a high sensitivity for making the correct diagnosis of CSP after IVF-ET, which is helpful for clinical intervention and avoiding severe complications. For patients with a history of cesarean section, thinner ET on the transfer day and bigger body mass index (BMI) seem to be risk factors for CSP; single blastocyst transfer should be recommended to decrease the possibility of HCSP. The clinical significance of this study still needs to be considered.
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.
