Abstract
Background As birth policy can affect maternal and infant health, we sought to identify whether and how the introduction of the two-child policy might have affected the prevalence of placenta previa in pregnant women in mainland China. Methods In this update meta-analysis and systematic review, we searched PubMed, Web of Science, the Cochrane Library, Weipu, Wanfang, and the China National Knowledge Infrastructure (CNKI) databases for studies evaluating the prevalence of placenta previa in China published between the inception of each database and March 2024, with no restrictions. Two investigators independently extracted the data from each included study. We then combined the prevalence of placenta previa using random-effects models. Results We included 128 studies in our analysis, 48 more than in our previous review. The prevalence of placenta previa among Chinese pregnant women was 1.44% (95% confidence interval (CI) = 1.32, 1.56). After the implementation of the two-child policy, the prevalence increased significantly, from 1.25% (95% CI = 1.16, 1.34) to 4.12% (95% CI = 3.33, 4.91). Conclusions The prevalence of placenta previa increased significantly from the one-child policy period to the two-child policy period among mainland Chinese pregnant women, with varying trends across regions. This change requires the attention of health officials and timely adjustment of resource allocation policies. Registration PROSPERO: CRD42021262309.

Changes in the characteristics and outcomes of high-risk pregnant women who delivered prior to and after China's universal two-child policy: a real-world retrospective study, 2010-2021. BMC Public Health 2024; 24:336. [PMID: 38297279 PMCID: PMC10829306 DOI: 10.1186/s12889-024-17810-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Accepted: 01/18/2024] [Indexed: 02/02/2024] Open
Abstract
BACKGROUND In 2016, the "universal two-child" policy, allowing each couple to have two children, was introduced in China. The characteristic change of the long-term period after the implementation of the universal two-child policy was unclear. We studied trends in the obstetric characteristics and their potential impact on the rates of cesarean section and preterm birth in the era of China's universal two-child policy. METHODS A tertiary center-based study (2010-2021) retrospectively focused single high-risk pregnancies who delivered from the one-child policy period (OCP, 2010-2015) to the universal two-child policy period (TCP, 2016-2021). A total of 39, 016 pregnancies were enrolled. Maternal demographics, complications, delivery mode and obstetric outcomes were analyzed. Furthermore, logistic regression analysis was used to explore the association between the cesarean section rate, preterm birth and implementation of the universal two-child policy, adjusting maternal age, parity, and fetal distress. RESULTS Ultimately a total of 39,016 pregnant women met the criteria and were included in this analysis. The proportion of women with advanced maternal age (AMA) increased from 14.6% in the OCP to 31.6% in the TCP. The number of multiparous women increased 2-fold in the TCP. In addition, the overall rate of cesarean section significantly decreased over the policy change, regardless of maternal age, whereas the risk of preterm birth significantly increased in the TCP. Adjusting for maternal age, parity and fetal distress, the universal two-child policy showed a significantly favorable impact on the cesarean section rate (RR 0.745, 95%CI (0.714-0.777), P < 0.001). Compared to the OCP group, a higher increase in fetal distress and premature rupture of membranes (PROM) were observed in the TCP group. In pregnancies with AMA, there was no increase in the risk of postpartum hemorrhage, whereas more women who younger than 35 years old suffered from postpartum hemorrhage in TCP. The logistic regression model showed that the universal two-child policy was positively associated with the risk of postpartum hemorrhage (RR: 1.135, 95%CI: 1.025-1.257, P = 0.015). CONCLUSIONS After the implementation of the universal two-child policy in China, the rate of the cesarean section significantly decreased, especially for women under 35 years old. However, the overall risk of postpartum hemorrhage increased in women under 35 years old, while there was no change in women with AMA. Under the new population policy, the prevention of postpartum hemorrhage in the young women should not be neglected.

Effect of Personality and Pain Catastrophizing on Postoperative Analgesia Following Cesarean Section: A Prospective Cohort Study. J Pain Res 2024; 17:11-19. [PMID: 38192365 PMCID: PMC10771724 DOI: 10.2147/jpr.s443230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Accepted: 12/28/2023] [Indexed: 01/10/2024] Open
Abstract
Purpose This study aimed to investigate the effects of different psychological personalities and pain catastrophizing levels on postoperative analgesia in patients undergoing cesarean section. Patients and Methods Puerperas who underwent cesarean section at our hospital between January and August 2023 were recruited into the study and assessed using the Eysenck Personality Questionnaire-Revised Short Scale (EPQRSC) and Pain Catastrophizing Scale (PCS). Data on the numerical pain intensity at rest and during activity 24 h after surgery, number and dosage of analgesia pumps, and satisfaction with analgesia were recorded. According to the numerical pain score during activity 24 h post-operation, the patients were divided into the analgesia incomplete group (≥4) and control group (<4). Univariate analysis, Spearman correlation analysis, and binary logistic regression analysis were used to evaluate the influence of personality characteristics and PCS on postoperative analgesia. Results A total of 778 women were included in the study. The incidence of inadequate analgesia was 89.8%. The satisfaction rate of analgesia was 66.8%. Univariate analysis showed that extraversion; neuroticism; PCS; numbers of previous cesarean delivery; ASA; analgesic satisfaction; and 24-h analgesia pump compressions and dosage were associated with postoperative analgesia after cesarean section (P<0.05). Using binary logistic regression analysis, the first cesarean section (odds ratio [OR]=0.056, 95% confidence interval [CI]=1.913-19.174), the number of 24-h analgesic pump compressions (OR=8.464, 95% CI=0.356-0.604), extraversion (OR=0.667, 95% CI=0.513-0.866), neuroticism (OR=1.427, 95% CI=1.104-1.844), and PCS (OR=7.718, 95% CI=0.657-0.783) were factors affecting postoperative analgesia. Conclusion The incidence of inadequate analgesia after a cesarean section was high (89.8% on the first day after surgery). Formulating accurate analgesia programs for women undergoing cesarean section with extraversion, neuroticism personality characteristics, and pain catastrophizing behaviors is necessary for improving their postoperative analgesia effects and satisfaction and promoting postpartum comfort.

Low-Value Surgical Procedures in Low- and Middle-Income Countries: A Systematic Scoping Review. JAMA Netw Open 2023; 6:e2342215. [PMID: 37934494 PMCID: PMC10630901 DOI: 10.1001/jamanetworkopen.2023.42215] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Accepted: 09/22/2023] [Indexed: 11/08/2023] Open
Abstract
Importance Overuse of surgical procedures is increasing around the world and harms both individuals and health care systems by using resources that could otherwise be allocated to addressing the underuse of effective health care interventions. In low- and middle-income countries (LMICs), there is some limited country-specific evidence showing that overuse of surgical procedures is increasing, at least for certain procedures. Objectives To assess factors associated with, extent and consequences of, and potential solutions for low-value surgical procedures in LMICs. Evidence Review We searched 4 electronic databases (PubMed, Embase, PsycINFO, and Global Index Medicus) for studies published from database inception until April 27, 2022, with no restrictions on date or language. A combination of MeSH terms and free-text words about the overuse of surgical procedures was used. Studies examining the problem of overuse of surgical procedures in LMICs were included and categorized by major focus: the extent of overuse, associated factors, consequences, and solutions. Findings Of 4276 unique records identified, 133 studies across 63 countries were included, reporting on more than 9.1 million surgical procedures (median per study, 894 [IQR, 97-4259]) and with more than 11.4 million participants (median per study, 989 [IQR, 257-6857]). Fourteen studies (10.5%) were multinational. Of the 119 studies (89.5%) originating from single countries, 69 (58.0%) were from upper-middle-income countries and 30 (25.2%) were from East Asia and the Pacific. Of the 42 studies (31.6%) reporting extent of overuse of surgical procedures, most (36 [85.7%]) reported on unnecessary cesarean delivery, with estimated rates in LMICs ranging from 12% to 81%. Evidence on other surgical procedures was limited and included abdominal and percutaneous cardiovascular surgical procedures. Consequences of low-value surgical procedures included harms and costs, such as an estimated US $3.29 billion annual cost of unnecessary cesarean deliveries in China. Associated factors included private financing, and solutions included social media campaigns and multifaceted interventions such as audits, feedback, and reminders. Conclusions and Relevance This systematic review found growing evidence of overuse of surgical procedures in LMICs, which may generate significant harm and waste of limited resources; the majority of studies reporting overuse were about unnecessary cesarean delivery. Therefore, a better understanding of the problems in other surgical procedures and a robust evaluation of solutions are needed.

Abstract
PURPOSE This study aimed to perform a systematic review of patients with Herlyn-Werner-Wunderlich syndrome (HWWS) and present the prevalence of symptoms, anatomical variants, endometriosis, surgical interventions, and short- and long-term outcomes. METHODS A structured search was performed in PubMed, Scopus, Embase, and China National Knowledge Infrastructure, and studies published between 1 January, 2000 and 19 April, 2022 were included. The following data on HWWS were recorded: symptoms, anatomical variations, surgical interventions and short- and long-term outcomes. RESULTS A total of 1673 patients were included in our analysis. The main symptoms were dysmenorrhea (53.8%), abnormal uterine bleeding (28.9%), and vaginal discharge (26.6%). The principal anomalies were right-obstructed hemivagina (57.3%), haematocolpos (81.7%), uterus didelphys (88.8%), and ipsilateral renal agenesis (93.1%). A majority of patients belonged to classification 1.1 (46.7%), with a blind hemivagina, and classification 2.1 (39.2%), with a small communication between two vaginas. The mainstay of treatment was vaginal septum excision (91.8%). Minimally invasive surgery (48.5%) was performed only after vaginal surgery (61.9%), and only a few patients required a second surgery (2.2%). Endometriosis was found in 9.6% of the patients. Fifty-two percent of them had ipsilateral ovarian endometriosis cysts. Pregnancy rate of these patients was 72.1%. The rate of adverse pregnancy outcomes was 22.4%. The caesarean section rate was 61.2%. CONCLUSIONS Patients with HWWS presented with nonspecific symptoms and demonstrated various combinations of anomalies. The most common anatomical variants are classifications 1.1 and 2.1. Vaginal septum excision is effective in relieving symptoms and preventing complications, with hysteroscopic surgery as an option where there is concern about protecting the hymen from minor injury. The pregnancy rate for these patients after surgery was satisfactory, and the rate of adverse pregnancy outcomes after surgery was acceptable. We advise females with urological anomalies to be screened for Müllerian anomalies because of the close association between these two types of anomalies. Thus, HWWS contributes to the occurrence of endometriosis; however, more research is required to investigate the relationship between pelvic endometriosis and HWWS.

Abstract
BACKGROUND Caesarean-section (C-section) may influence children's long-term health by affecting bacterial colonization. However, few studies have focused on the association between C-section delivery (CSD) and dental caries, and previous conclusions have been conflicting. This study aimed to explore whether CSD would increase the risk of early childhood caries (ECC) in preschool children in China. METHODS This study was a retrospective cohort study. Three-year-old children with full primary dentition were included through the medical records system. Children in the nonexposure group were vaginally delivered (VD), while children in the exposure group were delivered through C-section. The outcome was the occurrence of ECC. After agreeing to participate in this study, guardians of included children completed a structured questionnaire on maternal sociodemographic factors, children's oral hygiene and feeding habits. The chi-square test was used to determine differences in the prevalence and severity of ECC between the CSD and VD groups and to analyse the prevalence of ECC according to sample characteristics. Subsequently, potential risk factors for ECC were preliminarily identified through univariate analysis, and the adjusted odds ratios (ORs) were further calculated through multiple logistic regression analysis after controlling for confounding factors. RESULTS The VD group included 2115 participants while CSD group included 2996 participants. The prevalence of ECC was higher in CSD children than in VD children (27.6% vs. 20.9%, P < 0.05), and the severity of ECC in CSD children was higher (mean number of decayed, missing, and filled teeth, dmft: 2.1 vs. 1.7, P < 0.05). CSD was a risk factor for ECC in 3-year-old children (OR = 1.43, 95% CI = 1.10-2.83). In addition, irregular tooth brushing and always prechewing children's food were risk factors for ECC (P < 0.05). Low maternal educational attainment (high school or below) or socioeconomic status (SES-5) may also increase the prevalence of ECC in preschool children and CSD children (P < 0.05). CONCLUSIONS CSD would increase the risk of ECC in 3-year-old Chinese children. Paediatric dentists should devote more attention to the development of caries in CSD children. Obstetricians should also prevent excessive and unnecessary CSD.

Front Genet 2023; 13:1058261. [PMID: 36685814 PMCID: PMC9846508 DOI: 10.3389/fgene.2022.1058261] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Accepted: 12/08/2022] [Indexed: 01/05/2023] Open
Abstract
Introduction: Though embryonic chromosome abnormalities have been reported to be the most common cause of missed abortions, previous studies have mainly focused on embryonic chromosome abnormalities of missed abortions, with very few studies reporting that of non-missed abortion. Without chromosome studies of normal abortion samples, it is impossible to determine the risk factors of embryo chromosome abnormalities and missed abortion. This study aimed to investigate the maternal and embryonic chromosome characteristics of missed and non-missed abortion, to clarify the questions that how many missed abortions are caused by embryonic chromosomal abnormalities and what are their risk factors. Material and methods: This study was conducted on 131 women with missed or non-missed abortion from the Longitudinal Missed Abortion Study (LoMAS). Logistic regression analysis was used to identify the association between maternal covariates and embryonic chromosomal abnormalities and missed abortions. Data on the characteristics of women with abortions were collected. Results: The embryonic chromosome abnormality rate was only 3.9% in non-missed abortion embryos, while it was 64.8% in missed-abortion embryos. Assisted reproductive technology and prior missed abortions increased the risk of embryonic chromosome abnormalities by 1.637 (95% CI: 1.573, 4.346. p = 0.010) and 3.111 (95% CI: 1.809, 7.439. (p < 0.001) times, respectively. In addition, as the age increased by 1 year, the risk of embryonic chromosome abnormality increased by 14.4% (OR: 1.144, 95% CI: 1.030, 1.272. p = 0.012). Moreover, advanced age may lead to different distributions of chromosomal abnormality types. Conclusion: Nearly two-thirds of missed abortions are caused by embryonic chromosomal abnormalities. Moreover, advanced age, assisted reproductive technology, and prior missed abortions increase the risk of embryonic chromosomal abnormalities.
