Physical activity levels and influencing factors among pregnant women in China: A systematic review and meta-analysis.

BACKGROUND: Physical activity during pregnancy has been recommended as an effective measure to prevent various pregnancy complications. However, global physical activity participation during pregnancy is not optimal, and the factors influencing physical activity participation during pregnancy need to be further investigated. In China, where there are no localized guidelines for physical activity during pregnancy, the prevalence of meeting recommended physical activity levels among Chinese pregnant women is still unclear. OBJECTIVES: This study aimed to comprehensively review the prevalence of meeting recommended physical activity levels among pregnant women in China and to further explore the factors influencing physical activity participation during pregnancy. DESIGN: This was a systematic review and meta-analysis. METHODS: A systematic review was conducted in both English and Chinese databases from inception until August 1, 2023. Two reviewers independently screened literature, assessed study eligibility and extracted data. The Agency for Healthcare Research and Quality was used to evaluate methodological quality of included studies. The pooled prevalence was calculated using a random-effects model. Subgroup analyses were conducted to explore sources of heterogeneity. RESULTS: A total of 12 cross-sectional studies, including 11,323 Chinese pregnant women with a mean age ranging from 27.0 to 33.0 years, met the inclusion criteria. The prevalence of meeting recommended physical activity levels among pregnant women in China was 21.0 % (95 % confidence interval (CI):12.5 %-29.5 %). A higher prevalence of meeting recommended physical activity levels was observed among pregnant women who were in their second trimester, who were living in the southern region, who were assessed by validated questionnaires, and who used 150 min physical activity per week as a criterion for meeting recommendation. CONCLUSIONS: The findings suggested a low prevalence of meeting recommended physical activity levels among Chinese pregnant women, which was affected by a variety of factors. It is recommended that further research be conducted in the future to explore physical activity intervention strategies for women of childbearing age before and during pregnancy based on the factors affecting physical activity to improve physical activity compliance, maternal and child health and population quality.

Discharge preparation experiences and needs of intergenerational caregivers of neonatal intensive care unit preterm: A qualitative study.

PURPOSE: This study aimed to explore the real experiences and needs of neonatal intensive care unit (NICU) preterm intergenerational caregivers for discharge preparation and provide a basis for nursing staff to formulate systemic and personalized health education plans and continuous nursing plans for preterm discharge. DESIGN AND METHODS: This was a descriptive qualitative study. An objective sampling method was used to select 16 intergenerational caregivers of preterm infants admitted to the NICU of tertiary obstetrics and gynecology hospitals in Zhejiang and Jilin provinces from December 2023 to February 2024. Semi-structured interviews were conducted on the day of discharge of the preterm infants and six weeks after discharge. Colaizzi's seven-step analysis method was used to analyze the interview data. RESULTS: Based on the existence, relatedness, and growth (ERG) theory, the discharge preparation experiences and needs of neonatal intergenerational caregivers in the NICU were summarized into three themes: psychological condition, care capacity condition, and multi-party support needs. CONCLUSIONS: In the process of hospital discharge preparation, intergenerational caregivers of premature infants in NICU have multiple needs, including enhancing nursing ability and obtaining psychological and multi-party support. It is helpful to take effective interventions to improve their readiness for discharge. PRACTICE IMPLICATIONS: The nursing staff should develop personalized discharge health education plans and continuous nursing plans to improve the level of discharge preparation. PATIENT OR PUBLIC CONTRIBUTIONS: There were no patient or public contributions.

Theory-based interventions aimed at promoting physical activity in pregnant women: A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVES: The objectives were to assess (i) the quality of theory implementation, (ii) the application of behavior change techniques, and (iii) the effectiveness of theory-based interventions in promoting physical activity in pregnant women and improving maternal and neonatal outcomes. METHODS: A systematic search was conducted across 8 databases (Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, EMBASE, MEDLINE, APA PsycINFO, PubMed, SPORTDiscus, and Web of Science) to identify randomized controlled trials published from database inception to 8 July 2023. The Cochrane risk-of-bias 2.0 tool was used to evaluate the quality of the included studies. The theory coding scheme was used to measure the quality of theory implementation, and behavior change techniques were coded according to behavior change taxonomy (version 1). The meta-analysis was performed using RevMan 5.3. The Grading of Recommendations, Assessment, Development, and Evaluation Approach was used to assess the certainty of evidence. RESULTS: Eleven studies met the study criteria. Nine studies were based on one theory, while two studies were based on a combination of two theories. The quality of theory implementation was generally moderate. A total of 24 unique behavior change techniques were extracted. The most commonly used types of behavior change techniques were 'instruction on how to perform the behavior' (n = 9), 'goal setting' (behavior) (n = 8), 'action planning' (n = 7), and 'information about health consequences' (n = 7). Theory-based interventions significantly improved moderate-to-vigorous physical activity (standardized mean difference (SMD) = 0.17, 95 % confidence interval (CI) [0.04, 0.30], P = 0.01; moderate certainty of evidence), reduced the average gestational weight gain per week (mean difference (MD) = -0.06, 95 % CI [-0.11, -0.01], P = 0.02; moderate certainty of evidence), and decreased the incidence of gestational diabetes mellitus (risk ratio (RR) = 0.64, 95 % CI [0.46, 0.89], P = 0.008; high certainty of evidence). However, the effects of theory-based interventions on total physical activity, total gestational weight gain and the incidence of gestational hypertension and preterm delivery were unclear (P > 0.05). CONCLUSIONS: (i) Most of the studies exhibited a moderate level of theory implementation quality. (ii) The use of theories varies, but common behavior change techniques were found across studies. (iii) Theory-based interventions can improve physical activity and maternal and neonatal outcomes and appear to be safe. Appropriate health behavior theories and behavior change techniques should be fully utilized in future interventions. REGISTRATION: PROSPERO: CRD42023440886. TWEETABLE ABSTRACT: Theory-based interventions can improve physical activity and maternal and neonatal outcomes and appear to be safe. Appropriate health behavior theories and behavior change techniques should be fully utilized in the development of future interventions.

Effectiveness of web-based interventions for women with urinary incontinence: protocol for a systematic review and meta-analysis of randomised controlled trials.

INTRODUCTION: Urinary incontinence (UI) is one of the most common chronic diseases among women, which can endanger their physical and mental health and incur a heavy financial burden on both individuals and society. Web-based interventions (WBIs) have been applied to manage women's UI, but their effectiveness has remained inconclusive. This systematic review and meta-analysis aims to explore the effectiveness of WBIs on self-reported symptom severity, condition-specific quality of life, adherence to pelvic floor muscle training (primary outcomes) and other extensive secondary outcomes among women with UI. We also aimed to investigate whether intervention characteristics (format, interactivity and main technology) have impacts on the effectiveness of primary outcomes. METHODS AND ANALYSIS: This systematic review protocol was developed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidelines. 10 electronic databases will be comprehensively searched from their inception to 1 May 2024, along with grey literature searches and manual reviews of relevant reference lists to identify eligible randomised controlled trials. The methodological quality of the included studies will be assessed by two reviewers based on the Cochrane Risk of Bias Tool. Meta-analyses will be conducted via Stata V.12.0. Leave-one-out sensitivity analyses will be performed, and publication bias will be evaluated using funnel plots and Egger's test. Subgroup analyses regarding intervention format, interactivity and main technology will be carried out. ETHICS AND DISSEMINATION: No ethics approval is needed for this review since no primary data are to be collected. The results of this review will help develop an optimal WBI for women with UI, thereby providing them with maximum benefits. The findings will be disseminated via a peer-reviewed journal or conference presentation. PROSPERO REGISTRATION NUMBER: CRD42023435047.

Physical activity changes and influencing factors among Chinese pregnant women: a longitudinal study.

OBJECTIVE: Participating in physical activity during pregnancy has benefited a lot from maternal and child health. However, there are few longitudinal studies describing activity patterns and related factors during pregnancy. The aim of this study is to investigate longitudinal physical activity changes and the influencing factors of Chinese pregnant women. METHODS: From January to August 2020, 240 pregnant women were recruited in Hangzhou, China. Physical activity during pregnancy was assessed in the first, second, and third trimesters of pregnancy by using the Pregnancy Physical Activity Questionnaire. RESULTS: The daily energy consumption during first, second, and third trimesters was 20.55, 20.76, 17.19 METs-h/d. The results of repeated-measure analysis of variance and pairwise comparison showed that the total daily energy consumption of physical activity in the third trimester was significantly lower than that in the first and second trimesters, with statistical significance (p < 0.001). The generalized estimation equation showed that education level, pre-pregnancy BMI, gravidity, unnaturally conceived and pre-pregnancy exercise habits were the influencing factors of physical activity during pregnancy (p < 0.05). CONCLUSION: Physical activity levels of pregnant women during different trimester were not optimistic. In order to improve physical activity during pregnancy and promote the health status of both mother and the developing baby, more attention should be paid on pregnant women with low education level, high BMI before pregnancy, primipara, unnaturally conceived and no good exercise habits before pregnancy.

Epidemiological trends and risk factors related to lower urinary tract symptoms around childbirth: a one-year prospective study.

BACKGROUND: Lower urinary tract symptoms (LUTS) are prevalent and distressing concerns for women worldwide. The prevalence of LUTS reaches the first peak during pregnancy and postnatal period. However, less attention has been paid to LUTS around childbirth and little progress has been made in the prevention of LUTS. Understanding the epidemiological characteristics of LUTS around childbirth would inform decision making for health care providers and perinatal women in the prevention of LUTS. The study aims to investigate the epidemiological trends and associated risk factors related to LUTS around childbirth. METHODS: Pregnant women were consecutively enrolled during pregnancy in the obstetrical wards of a tertiary hospital and followed up at 6-8 weeks and one year postpartum through a prospective design. Urinary incontinence was assessed with the International Consultation on Incontinence Modular Questionnaire-Urinary Incontinence Short Form. Other symptoms were measured with questions based on definitions of the International Incontinence Society. Multiple logistic regression was used to examine the risk factors for LUTS including urinary incontinence, increased daytime frequency, nocturia and urgency. The report followed the STROBE statement. RESULTS: A total of 1243 pregnant women participated in this study. The prevalence of at least one type of storage symptoms was 94%, 55% and 35% in late pregnancy, at 6-8 weeks and one year postpartum, respectively. The prevalence of urinary incontinence remained at 21% within one year postpartum. The majority of the participants suffered from mild to moderate urinary incontinence. Age, job, BMI before pregnancy, gestational diabetes mellitus, urinary tract infection history, previous history of LUTS, age at first birth and birth mode were predictors of LUTS one year postpartum. CONCLUSION: LUTS were highly prevalent during pregnancy and postnatal period. The prevalence of urinary incontinence was more stable than that of other LUTS within one year postpartum. Women aged more than 35 years, engaging in manual work, with gestational diabetes mellitus, with a history of urinary tract infection and LUTS, with advanced age at first birth and vaginal delivery were more likely to suffer from LUTS postpartum. The findings provided a novel and deep insight into the epidemiological trends and related risk factors of LUTS around childbirth.

Prevalence of Chinese pregnant women meeting physical activity recommendation and its influencing factors: a protocol for systematic review and meta-analysis.

INTRODUCTION: Regular physical activity during pregnancy is effective in preventing diseases and promoting the health outcomes of mothers and babies. However, the level of physical activity among them is not ideal. Especially in China, the proportion of pregnant women who meet the recommendation of physical activity in the guidelines is even lower. Thus, we aim to evaluate the prevalence of meeting physical activity recommendation and its influencing factors during pregnancy in China. METHODS AND ANALYSIS: This protocol is developed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidelines. PubMed, Web of Science, Scopus, CINAHL, MEDLINE, PsycINFO, EMBASE, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (Weipu) and WanFang Data will be comprehensively searched by two reviewers. Studies that report the prevalence of Chinese pregnant women meeting physical activity recommendation will be included. Two reviewers will independently assess eligibility, extract data and evaluate methodological quality. Data including authors, publication years, language, geographical region, tools, trimesters, prevalence and influence factors will be extracted. Data will be analysed by Stata V.11 statistical software. ETHICS AND DISSEMINATION: No formal ethics approval is required for this protocol and no primary data are to be collected. Findings from this review may be useful to develop interventions for the physical activity of pregnant women in China. The results will be disseminated through peer-reviewed journals, conference presentations and public events. PROSPERO REGISTRATION NUMBER: CRD42022372722.

Effect of non-mechanical bowel preparation on postoperative gastrointestinal recovery following surgery on malignant gynecological tumors: A randomized controlled trial.

OBJECTIVE: To investigate the efficacy and safety of non-mechanical bowel preparation (non-MBP) in patients undergoing surgery for malignant gynecological tumors. METHODS: Patients undergoing surgery for a gynecological malignancy (n = 105) were randomized to receive mechanical bowel preparation (MBP) or non-MBP. Parameters indicating postoperative gastrointestinal function recovery were the primary outcomes. The secondary outcomes included the number of postoperative complaints, the plasma levels of D-lactate and diamine oxidase (DAO), ease of visualization of the surgical field, involuntary defecation during surgery, operation time, wound healing, surgical site infection, length of hospital stay, and tolerance to MBP. RESULTS: The participants in the non-MBP group exhibited shorter time intervals until the first postoperative bowel movement (27.87 vs. 29.48 h), first passage of flatus (50.96 vs. 55.08 h), and first passage of stool (75.94 vs. 98.50 h) compared with the MBP group, while they also exhibited fewer postoperative gastrointestinal symptoms, including nausea (18.9% vs. 38.5%), vomiting (26.4% vs. 51.9%), abdominal pain (34.0% vs. 78.9%), and bloating (3.8% vs.26.9%). The plasma D-lactate and DAO levels were significantly increased following bowel preparation compared with the baseline levels in the MBP group (2.93 vs. 5.68 nmol/mL and 20.46 vs. 54.49 ng/mL, respectively), but no such differences were observed in the non-MBP group. Compared with the MBP group, surgical field visualization was superior (92.45% vs. 78.85%), and the operation time was shorter (173.58 vs. 203.88 min) in the non-MBP group. The patients undergoing MBP complained of bloating (182.35%), an unpleasant taste (78.43%), sleep disturbance (70.59%), nausea (68.63%), abdominal pain (64.71%), vomiting (45.10%), polydipsia (33.33%), dizziness (25.49%), and headache (7.84%). CONCLUSIONS: The use of non-MBP in patients undergoing surgery for gynecological malignancies is more conducive to the postoperative recovery of gastrointestinal function.

Barriers and enablers of pelvic floor rehabilitation behaviours in pregnant women with stress urinary incontinence: a qualitative analysis using the theoretical domains framework.

BACKGROUND: Stress urinary incontinence during pregnancy is closely related to the occurrence of postpartum and long-term urinary incontinence. Early pelvic floor management is of great significance in promoting the recovery of pelvic floor tissues in pregnant women. However, effective management of urinary incontinence is far from achievable owing to the low adherence of pregnant women in partaking in pelvic floor rehabilitation. As a comprehensive framework for behavioural theory, the Theoretical Domain Framework allows for comprehensive identification of behavioural determinants. Using Theoretical Domain Framework, this study aimed to identify barriers and enablers of pelvic floor rehabilitation behaviours in pregnant women with stress urinary incontinence. METHODS: A descriptive, qualitative design was used in this study. Face-to-face semi-structured interviews were conducted with pregnant women with stress urinary incontinence based on the Theoretical Domain Framework. The data were analysed using a combination of inductive and deductive methods. RESULTS: Twenty pregnant women with stress urinary incontinence were interviewed. Seven themes were summarised and used to explain the pelvic floor rehabilitation behaviours of pregnant women with stress urinary incontinence. The seven themes were (1) individual knowledge and experience of pelvic floor management, (2) judgments about expected outcomes, (3) interactions of interpersonal situations, (4) environment, resources, and decision-making processes, (5) personal goal-setting and efforts towards behaviour change, (6) emotional influences on decision-making, and (7) personal characteristics. Besides the "Optimism" domain, 13 of the 14 Theoretical Domains Framework domains were found to influence pregnant patients' pelvic floor rehabilitation behaviours after deductive mapping of themes to the Theoretical Domains Framework. In addition, the inductive analysis generated a theme of personal characteristics that did not map to any of the Theoretical Domains Framework domains. CONCLUSIONS: The pelvic floor rehabilitation behaviours of pregnant women with stress urinary incontinence are complex and are affected by many factors. The findings confirm the need for multiple interventions to support pelvic floor management in pregnant women with stress urinary incontinence, focusing on enhancing knowledge and skills in pelvic floor care and using appropriate behaviour change techniques (such as prompts) to provide a supportive environment.

The relationship between psychological contract and occupational wellbeing of mother-infant care helpers in Zhejiang Province.

BACKGROUND: Mother-infant care (MIC) helpers have become an indispensable part in hospital services. In order to stabilize the MIC workforce, it is essential for administrators to have a solid understanding of what may influence occupational wellbeing. This article aims to explore how demographic characteristics and psychological contract affect occupational wellbeing among MIC helpers in Zhejiang Province, China. METHODS: This is a quantitative, cross-sectional study with MIC helpers in obstetrics from 20 hospitals in Zhejiang Province. A questionnaire including demographic data, a psychological contract scale and an occupational wellbeing scale was used in this study. Multiple linear regression was conducted to investigate the relationships between demographic characteristics, psychological contract and occupational wellbeing. RESULTS: This study surveyed 260 MIC helpers and found out the mean score of the psychological contract was 4.38 and the mean score of the occupational wellbeing was 4.01. Monthly income and psychological contract were significant predictors of occupational wellbeing (F = 142.167, p < 0.001), which explained 62.1% of the total amount of variance in occupational wellbeing. Psychological contract was the most important predictor of occupational wellbeing. CONCLUSIONS: Administrators should pay attention to the effect of psychological contract on occupational wellbeing of the MIC helpers in China. Focusing on the inner needs should be considered as a strategy for stabilizing the team.

Psychometric properties of the Chinese version of the fathers' fear of childbirth scale: A cross-sectional study.

Background and Aim: Fear of childbirth (FOC) is one of the most common mental health concerns among expectant fathers, which can cause adverse consequences for themselves and their families. A valid and accurate tool is the key to the identification of FOC. This study aimed to translate and culturally adapt the fathers' fear of childbirth scale (FFCS) into simplified Chinese and test the scale's psychometric properties among expectant fathers in mainland China. Methods: Researchers obtained translation permission and followed the multiphase translation guidelines to develop the Chinese version of the fathers' fear of childbirth scale (C-FFCS). Relevant psychometric properties were selected for the scale's psychometric validation on the basis of the Consensus-based Standards for the Selection of Health Status Measurement Instruments checklist. In this cross-sectional study, two samples of expectant fathers were collected in a university-affiliated hospital in Hangzhou between September and October 2022. Results: A total of 381 expectant fathers completed the C-FFCS, resulting in an effective response rate of 95.6%. The C-FFCS is a 3-factor structure consisting of 16 items, which explained 66.374% of the total variance. The content validity index of items ranged from 0.833 to 1.00, and the scale-level content validity index was 0.931. The confirmatory factor analysis confirmed the scale's 3-factor structure. Evidence of convergent validity (average variance extracted = 0.508-0.780) as well as discriminant validity offered excellent psychometric support. The Cronbach's α coefficient, McDonald's ω coefficient, intraclass correlation coefficient, Spearman-Brown coefficient, and Guttman split-half coefficient are within the satisfactory range (> 0.80). Significant correlations between the scores of the C-FFCS and Childbirth Attitude Questionnaire (r = 0.658, p < 0.01) and Fear of Birth Scale (r = 0.555, p < 0.01) both revealed good concurrent validity. The structure of C-FFCS was invariant across different parity groups, with no floor and ceiling effect. Conclusion: The C-FFCS was demonstrated to be a sound instrument with good reliability and validity for measuring Chinese expectant fathers' FOC levels. However, further studies are advocated to verify the C-FFCS among a larger sample that is more representative of the Chinese expectant father population.

Web-Based Interventions for Pregnant Women With Gestational Diabetes Mellitus: Systematic Review and Meta-analysis.

BACKGROUND: Effective management of gestational diabetes mellitus (GDM) is essential because it is one of the most prevalent diseases during pregnancy, and the consequent condition maternal hyperglycemia is closely related to considerable short- and long-term maternal and neonatal complications. Web-based interventions (WBIs), defined as therapeutic interventions offered via the web, have been implemented to assist in managing GDM owing to their advantages of high accessibility and efficiency, but findings across relevant studies are inconsistent. OBJECTIVE: This systematic review and meta-analysis aimed to evaluate the effectiveness of WBIs on glycemic control among pregnant women with GDM; examine whether specific types of intervention interactivity, format, and technology have beneficial effects on maternal glycemic control; and comprehensively assess the efficacy of WBIs in maternal behavioral outcomes, cognitive and attitudinal outcomes, mental health, maternal and neonatal clinical outcomes, and medical service use and costs among pregnant women with GDM. METHODS: PubMed, Embase, Cochrane Library, Web of Science, CINAHL, and PsycINFO were searched from their respective inception to November 19, 2022, to identify relevant randomized controlled trials and controlled clinical trials. The methodological quality of the included studies was assessed using the Effective Public Health Practice Project tool. Where possible, the data for all outcomes were meta-analyzed using the Stata software (version 12.0; StataCorp). Overall, 3 subgroup analyses and post hoc sensitivity analyses of maternal glycemic control parameters were performed. RESULTS: Overall, 25 publications arising from 21 randomized controlled trials and controlled clinical trials were included. The overall meta-analyses on glycemic control parameters demonstrated that WBIs could significantly improve fasting blood glucose (standardized mean difference=-1.764, 95% CI -2.972 to -0.557; P=.004) and 2-hour postprandial blood glucose (standardized mean difference=-1.433, 95% CI -2.561 to -0.304; P=.01) compared with the control group, whereas no significant effect was found on glycated hemoglobin and 1-hour postprandial blood glucose. The results of the subgroup analyses indicated that mobile app-delivered interventions with a personalized format and interactive function showed more beneficial effects on maternal glycemic control. Moreover, WBIs could significantly enhance compliance with the self-monitoring of blood glucose; increase the rate of normal vaginal delivery; and decrease the chance of emergency cesarean, admission to the neonatal intensive care unit, and composite neonatal complications. GDM knowledge, risk perception of the disease, self-efficacy, satisfaction with care, and medical service use of the participants in the WBI group were also improved compared with the control group. However, the effectiveness of WBIs on other secondary outcomes was either nonsignificant or uncertain. CONCLUSIONS: WBIs are a promising approach to GDM management. Personalized, interactive, and mobile app-delivered interventions seem more worthy of being recommended for future clinical practice. Further high-quality studies are required to verify these findings before making broad recommendations.

The single pregnancy predicting model of 1 minute Apgar score less than 7 after preterm birth: A retrospective study.

Preterm delivery is greatly associated with perinatal mortality and morbidity, while there is no objective way to identify high-risk newborns currently. This study aimed at discovering the risk factor for Apgar score less than 7 at 1 minute of preterm neonates born with vaginal delivery. A retrospective study was performed in single pregnancy women with a vaginal delivery before 37 weeks of gestation. All the preterm infants were categorized into three types: very preterm birth (28 to 32 weeks), moderate preterm birth (32 to 34 weeks) and late preterm birth (34 to 37 weeks). Risk factors were identified through logistic regression analysis in every category of newborns mentioned above. And the receiver operating characteristic analysis was used in continuous variables to determine the best threshold of the outcome. On the basis of the selected factors, the predicting models are created and its prognosticating ability is compared by the area under the curve. A nomogram was established for the proved best model. A total of 981 cases were investigated, of whom 55 were found with 1 min Apgar scores less than 7. The nomogram was set for the predicting model with larger area under the receiver operating characteristic curve, of which is 0.742(95% confidence interval = 0.670-0.805) in very preterm birth, with the variables of first and second labor stage(> = 1.6 hours), birthweight and MgSO4(magnesium sulfate), and is 0.807(95% confidence interval = 0.776-0.837) in late preterm birth, with the variables of second labor stage(> = 1.23 hours), birthweight, a history of previous cesarean delivery, fetal distress and placental abruption. The combination of first and second labor stage, newborn weight and MgSO4 use can predict 74.2% of 1 minute Apgar score < 7 in very preterm neonates. And 80.7% high-risk infants can be identified when second labor stage, newborn weight, VBAC (vaginal birth after cesarean) and the occur of placental abruption and fetal distress were combined in the predicting model for late preterm birth. These predicting models would bring out great assistance towards obstetricians and reduce unnecessary adverse fetal outcomes.

Inhibition of invasion and metastasis in choriocarcinoma by migration and invasion inhibitory protein.

INTRODUCTION: Choriocarcinoma is a highly invasive gynaecologic malignancy. Molecular mechanism of metastasis in choriocarcinoma is poorly understood. Migration and invasion inhibitory protein (MIIP) regulates cell migration and invasion. Therefore, we aimed to elucidate the function of MIIP in choriocarcinoma. METHODS: Choriocarcinoma cell lines, JAR and JEG-3, were transfected with lentivirus carrying the MIIP-interfering RNA (to downregulate MIIP expression) or left untransfected (negative control). Cell migration and invasion were studied using transwell migration assays and scratch assays. In vivo tumour burden was studied using tumour xenograft models in specific-pathogen-free nude mice and live imaging. We elucidated possible molecular signalling pathways using western blotting. RESULTS: In transwell migration and scratch assays MIIP-downregulated JAR and JEG-3 cells migrated and invaded faster compared to their respective negative control cells. Migration and invasion by the MIIP-upregulated SWAN cells was slower than that by negative control SWAN cells. Live imaging revealed that bioluminescence values were higher in MIIP-downregulated tumours than in the negative control tumours. Mice with MIIP-downregulated tumours had higher serum human chorionic gonadotropin (HCG) levels than those with negative control tumours. The MIIP expression was negatively correlated with that of histone deacetylase (HDAC6) and positively correlated with that of acetylated α-tubulin. DISCUSSION: Thus, MIIP-by inhibiting cellular motility in choriocarcinoma-acts as a tumour suppressor gene. This highlights a potential therapeutic target for refractory choriocarcinoma. Additionally, HDAC6 and acetylated α-tubulin may be involved in the regulatory effects of MIIP on the biobehaviour of choriocarcinoma cells.

Predicting Physical Activity in Chinese Pregnant Women Using Multi-Theory Model: A Cross-Sectional Study.

BACKGROUND: Physical activity (PA) brings many benefits to pregnant women and fetuses; however, the majority of pregnant women do not participate actively in PA during pregnancy. OBJECTIVES: This study aimed to: (1) assess the utility of Multi-Theory Model (MTM) to explain the intentions of PA behavior in Chinese pregnant women; (2) analyze the predictors in initiating and maintaining PA behavior based on MTM. METHODS: A cross-sectional study including pregnant women was conducted from March to June 2022 at a university hospital in Hangzhou, Zhejiang Province, China. Participants completed measures that included a self-developed demographic questionnaire and a 29-item MTM questionnaire. Descriptive statistics and stepwise multiple regression were used to analyze the data. The reliability was assessed by Cronbach's alpha and test-retest stability. The construct validity was evaluated by using exploratory factor (EFA) analysis and confirmatory factor analysis (CFA). RESULTS: A total of 450 pregnant women participated in this study. The score of the magnitude of intention to initiate and maintain PA behavior during pregnancy was 2.30 (1.08) and 2.24 (1.09). The overall Cronbach's alpha value was 0.857. A four-factor structure for initiation model and a three-factor structure for maintenance model were determined. Results of the CFA confirmed construct validity of subscales (initiation model: χ2 = 206.123, df = 140, p < 0.001, χ2/df = 1.472, RMSEA = 0.046, SRMR = 0.0432, GFI = 0.913, CFI = 0.982; maintenance model: χ2 = 49.742, df = 29, p < 0.001, χ2/df = 1.715, RMSEA = 0.057, SRMR = 0.0432, GFI = 0.958, CFI 0.985). The result of regression indicated that participatory dialogue (ß = 0.030; p = 0.002), behavioral confidence (ß = 0.128; p < 0.001), changes in physical environment (ß = 0.041; p = 0.005), trimester (ß = -0.192; p = 0.001), and Gestational Diabetes Mellitus (GDM) (ß = 0.408; p < 0.001) explained 52.1% variance in initiating PA behavior. Emotional transformation (ß = 0.197; p < 0.001), practice for change (ß = 0.083; p = 0.001), changes in social environment (ß = 0.063; p < 0.001), pre-pregnancy exercise habit (ß = -0.251; p = 0.001), and GDM (ß = 0.298; p = 0.003) were significantly associated with pregnant women's intentions to maintain PA behavior and explained 49.1% variance. CONCLUSIONS: The constructs of MTM were effective in explaining the intention to initiate and maintain PA behavior among Chinese pregnant women.

Effect of pelvic floor muscle training using mobile health applications for stress urinary incontinence in women: a systematic review.

BACKGROUND: Pelvic floor muscle training (PFMT) is the first-line treatment for urinary incontinence, but adherence to PFMT is generally poor. Currently, a number of novel strategies exist to facilitate adherence of PFMT. We sought to determine effectiveness of mHealth app-based PFMT for treating stress urinary incontinence (SUI) or stress-predominant mixed urinary incontinence (MUI) in women. The primary objective was to assess the effects of mHealth app-based PFMT and usual treatment on severity of the symptom, the quality of life (QoL) of users and the patient's global impression of improvement. The secondary objective was to assess how mHealth app use affects adherence of PFMT. METHODS: All randomized controlled trials and quasi-randomized controlled trials aimed at evaluating the effects of mHealth app-based PFMT in women with SUI or stress-predominant MUI were included. Twelve electronic databases, namely the Cochrane Library, PubMed, CINAHL, Embase, Web of science, OVID, SciELO, REHABDATA, PEDro database, Chinese CNKI and Wanfang and the Open Grey databases were used as search sources. The protocol was registered in PROSPERO (CRD 42020183515). This systematic review was developed following the PRISMA 2020 Checklist. The Cochrane Handbook for Systematic Reviews of Interventions for Randomized Controlled Trials was used to assess risk of bias in included studies. Two authors extracted the data into a standardized spreadsheet. RESULTS: Six studies that met the eligibility criteria were included. The full sample included 439 patients with treatment via mHealth app and 442 controls of usual treatment. ICIQ-UI SF, ICIQ-VS, and QUID scores decreased after follow-up in the mHealth app and control groups in six studies. ICIQ-LUTS QoL scores decreased after follow-up in the mHealth app and control groups in three studies. In only one study, ICIQ-VS QoL scores decreased after 1 month and 2 months of follow-up in the mHealth app group, but increased abruptly after 3 months of follow-up. EQ5D-VAS scores increased in both groups in one study. The percentage of PGI-I increased in the mHealth app group in three studies after follow-up. After follow-up in three studies, BPMSES scores and self-reported adherence scores increased in the mHealth app group relative to the initial time point, but in one study, at 6 months compared with 3 months of follow-up, adherence scores decreased slightly in the mHealth app group. CONCLUSIONS: This systematic review determined that mHealth app-based PFMT showed promise from the perspective of improving both outcomes and exercise adherence.

Cross-cultural adaptation and psychometric properties of the Chinese version of the postpartum depression literacy scale.

Background and aim: The postpartum depression literacy (PoDLi) of perinatal women is closely related to the occurrence, recognition, and treatment of postpartum depression, therefore valid instruments for evaluating the level of PoDLi are of great significance for both research and clinical practice. This study aimed to cross-culturally adapt the postpartum depression literacy scale (PoDLiS) into Chinese and to test its psychometric properties among Chinese perinatal women. Materials and methods: A cross-sectional study was conducted from April to May 2022 in a tertiary hospital in Hangzhou, Zhejiang Province, China. 619 out of the 650 perinatal women that were approached via a convenience sampling method completed the Chinese version of the PoDLiS (C-PoDLiS). Content validity [the content validity index of items (I-CVI) and scale-level content validity index (S-CVI)] was evaluated by an expert panel. Psychometric properties, including item analysis, structure validity (exploratory factor analysis, confirmatory factor analysis), convergent and discriminant validity, reliability (internal consistency, test-retest reliability), criterion validity (concurrent validity, predictive validity), and floor/ceiling effect were examined. Results: The final version of C-PoDLiS is a six-factor structure consisting of 27 items, which explained 61.00% of the total variance. Adequate content validity (I-CVI = 0.833-1.00, S-CVI = 0.920) was ensured by the expert panel. The modified confirmatory factor analysis model revealed that the 6-factor model fitted the data well (χ2/df = 1.532, root mean square error of approximation = 0.042, goodness of fit = 0.900, incremental fit index = 0.949, comparative fit index = 0.948, Tucker-Lewis index = 0.940). The total Cronbach's α was 0.862, the total McDonald's ω was 0.869, and the test-retest reliability coefficient was 0.856. Results of convergent validity (average variance extracted = 0.486-0.722) and discriminant validity provided good or acceptable psychometric support. Significant correlations between scores of the C-PoDLiS and Mental health literacy scale (r = 0.155-0.581, p < 0.01) and Attitudes toward seeking professional psychological help short form scale (r = 0.361-0.432, p < 0.01) supported good concurrent and predictive validity, respectively. No floor/ceiling effect was found. Conclusion: The C-PoDLiS was demonstrated to be a sound instrument with good reliability and validity for evaluating Chinese perinatal women's PoDLi levels. Its use in the future can facilitate data aggregation and outcome comparisons across different studies on this topic.

Web-based interventions for pregnant women with gestational diabetes mellitus: a systematic review and meta-analysis protocol.

INTRODUCTION: Gestational diabetes mellitus (GDM) is one of the most prevalent diseases during pregnancy, which is closely associated with many short-term and long-term maternal and neonatal complications and can incur heavy financial burden on both families and society. Web-based interventions have been used to manage GDM because of the advantages of high accessibility and flexibility, but their effectiveness has remained inconclusive. This systematic review and meta-analysis aims to comprehensively investigate the multidimensional effectiveness of web-based interventions for pregnant women with GDM, thereby aiding implementation decisions in clinical settings. METHODS AND ANALYSIS: This systematic review protocol strictly adheres to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines. Six electronic databases (PubMed, Web of Science, Cochrane Central Register of Controlled Trials, Embase, CINAHL and PsycINFO) will be comprehensively searched from their inception to 26 January 2022 to identify randomised controlled trials and controlled clinical trials regarding the efficacy of web-based interventions for pregnant women with GDM on glycaemic control, behavioural outcomes, cognitive and attitudinal outcomes, mental health, maternal and neonatal clinical outcomes, and medical service utilisation and costs. Two reviewers will independently conduct the study selection, data extraction and quality assessment. The methodological quality of included studies will be assessed using the Effective Public Health Practice Project assessment tool. The overall meta-analyses for each of the interested outcomes will be performed if the outcome data are sufficient and provides similar effect measures, as well as subgroup analyses for glycaemic control indicators based on the different types of intervention format, interactivity and technology. We will conduct a qualitative synthesis for studies that cannot be quantitatively synthesised. ETHICS AND DISSEMINATION: Ethics approval is not required for this review as no human participants will be involved. The results will be disseminated via a peer-reviewed journal or an academic conference. PROSPERO REGISTRATION NUMBER: CRD42022296625.

Effects of the original Gymnastics for Pregnant Women program on glycaemic control and delivery outcomes in women with gestational diabetes mellitus: A randomized controlled trial.

BACKGROUND: Gestational diabetes mellitus affects millions of pregnant women. Lifestyle intervention is recommended as the first-line treatment, in which exercise plays an important role. Effective and safe exercise is required to facilitate glycaemic control and improve delivery outcomes. OBJECTIVE: To investigate the efficacy and safety of the original Gymnastics for Pregnant Women program for glycaemic control and delivery outcomes improvement in gestational diabetes mellitus women. DESIGN: The study was a two-arm parallel randomized controlled clinical trial. SETTING: The study was conducted in a tertiary specialized maternity hospital in Hangzhou, China. PARTICIPANTS: Totally 131 eligible pregnant women were enrolled from June to December 2020. METHODS: Participants were randomly allocated to the control group (conventional intervention) or experimental group that engaged in the original Gymnastics for Pregnant Women program. The primary outcomes included glycaemic control during pregnancy and postpartum. Secondary outcomes included adverse events, maternal and neonatal outcomes. RESULTS: Participants showed a significant improvement in glycaemic control after engaging in the intervention for 2 weeks; the improvement was most significant in terms of the 2-h postprandial plasma glucose (P < 0.05). The fasting blood glucose and 2-h postprandial plasma glucose data indicated a higher glycaemic control rate in the experimental than control group (86.16% vs. 66.67%, P = 0.008; and 84.62% vs. 36.36% [6.09 ±â€¯0.79 vs. 6.96 ±â€¯1.06 mmol/L], P < 0.001, respectively). After delivery, the 2-h oral glucose tolerance test results indicated better glycaemic control in the experimental than control group (75.44% vs. 57.41% [6.93 ±â€¯1.44 vs. 7.79 ±â€¯2.03 mmol/L], P = 0.047). Additionally, the 2-h oral glucose tolerance test in the experimental group with reasonable exercise frequency (≥10 times per week) had the best glucose level (6.81 ±â€¯1.30 mmol/L), followed by the experimental group with a lower exercise frequency (<10 times per week) (7.35 ±â€¯1.83 mmol/L) and the control group (7.79 ±â€¯2.03 mmol/L). No statistical differences in maternal or neonatal outcomes were observed between the control and experimental groups (P > 0.05). In addition, there were no adverse events in the experimental group; however, in the control group, two cases experienced at least one hypoglycaemic episode and two cases received insulin during the study period. CONCLUSIONS: The original Gymnastics for Pregnant Women was associated with greater improvements in blood glucose levels during pregnancy and postpartum compared with a conventional intervention for women with gestational diabetes mellitus. REGISTRATION: ChiCTR2000033963 (2020-06-22). TWEETABLE ABSTRACT: The original Gymnastics for Pregnant Women program improves glycaemic control in GDM women but does not affect delivery outcomes.

The effectiveness of eHealth interventions on female pelvic floor dysfunction: a systematic review and meta-analysis.

INTRODUCTION AND HYPOTHESIS: eHealth interventions represent a promising novel strategy in pelvic floor management for women. Nevertheless, the effectiveness of eHealth interventions among women with or at risk of pelvic floor dysfunction (PFD) has not been adequately discussed to date. This study aimed to determine the effectiveness of eHealth interventions in preventing and treating PFD among women. METHODS: Eleven electronic databases were searched for randomized controlled trials (RCTs) from inception until August 28, 2021. RESULTS: Twenty-four RCTs were included in this meta-analysis that included 3691 women. The meta-analysis showed that eHealth interventions were not only vital for preventing PFD (pregnant women: pooled OR = 0.25, 95% CI: 0.14 to 0.45, p < 0.001; postnatal women: pooled OR = 0.19, 95% CI: 0.06 to 0.60, p = 0.005), but also for reducing the severity of PFD (pooled SMD = -0.63, 95% CI: -1.20 to -0.06, p = 0.031). In addition, compared with traditional care, eHealth interventions showed significant positive effects on several outcome indicators, including quality of life (pooled SMD = 0.49, 95% CI: 0.19 to 0.80, p = 0.002), pelvic floor type I muscle strength (pooled OR = 1.92, 95% CI: 1.30 to 2.82, p = 0.001), pelvic floor type II muscle strength (pooled OR = 2.04, 95% CI: 1.38 to 3.01, p < 0.001), sexual function (pooled SMD = 0.51, 95% CI: 0.29 to 0.73, p < 0.001), satisfaction (pooled OR = 3.93, 95% CI: 2.73 to 5.66, p < 0.001), and self-efficacy (pooled SMD = 2.62, 95% CI: 2.12 to 3.13, p < 0.001). CONCLUSIONS: eHealth interventions are an effective emerging treatment and preventive modality for female PFD. Higher quality, larger scale, and strictly designed RCTs are warranted to evaluate the effectiveness of eHealth interventions on female pelvic floor management.
