OBJECTIVES: Pelvic floor dysfunction is common among pregnant and postpartum women and significantly impacts quality of life. This study aims to translate the German Pelvic Floor Questionnaire for Pregnant and Postpartum Women into Chinese and to evaluate its reliability and validity in the Chinese population. METHODS: The questionnaire was translated using the Brislin model. A cross-sectional study was conducted among pregnant and postpartum women to assess the content validity, construct validity, Cronbach's α coefficient, test-retest reliability, and split-half reliability of the Chinese version. RESULTS: A total of 72 women were included, with 6.9% being pregnant and 93.1% postpartum; the age was (32.3±3.6) years. The Chinese version of the questionnaire contains 4 dimensions and 45 items. The content validity index of individual items ranged from 0.833 to 1.000, with a scale-level content validity index of 0.977 and intraclass correlation coefficients (ICCs) exceeding 0.90. The overall Cronbach's α coefficient was 0.891, with subscale coefficients ranging from 0.732 to 0.884 (all ICCs>0.70). The test-retest reliability of the total scale was 0.833, and for the 4 dimensions, bladder, bowel, prolapse, and sexual function, the values were 0.776, 0.579, 0.732, and 0.645, respectively. The split-half reliability was 0.74. CONCLUSIONS The Chinese version of the questionnaire demonstrated good reliability and validity, indicating its applicability in assessing pelvic floor dysfunction and associated risk factors during pregnancy and postpartum.

OBJECTIVES: To evaluate the impact of HBV infection on pre- and postpartum health-related quality of life (HRQoL) in pregnant women. METHODS: A prospective matched cohort consisting of 70 HBV-infected and 70 healthy pregnant women was recruited from the Fifth Affiliated Hospital of Guangzhou Medical University between April 17 and September 25, 2023. HRQoL of the participants was assessed at 16-24 weeks of gestation, between 32 weeks and delivery, and 5-13 weeks postpartum. Mixed linear models were used for evaluating temporal trends of HRQoL changes, and univariate ANOVA with multiple linear regression was used to identify the predictors of HRQoL. RESULTS: Compared with healthy pregnant women, HBV-infected pregnant women had consistently lower total HRQoL scores across all the 3 intervals, with the lowest scores observed between 32 weeks of gestation and delivery, during which these women had significantly reduced mental component scores (74.27±13.43 vs 80.21±12.9, P=0.009) and postpartum mental (76.52±16.19 vs 85.02±6.51, P<0.001) and physical component scale scores (77.17±14.71 vs 83.09±10.1, P=0.009). HBV infection was identified as an independent risk factor affecting HRQoL during late pregnancy and postpartum periods. Additional independent risk factors for postpartum HRQoL reduction included self-pay medical expenses, spouse's neutral attitude toward the current pregnancy, and preexisting comorbidities (all P<0.05). CONCLUSIONS HRQoL of pregnant women deteriorates progressively in late pregnancy, and HBV infection exacerbates reductions of physical function and role emotion in late pregnancy and after delivery, suggesting the importance of targeted interventions for financial burdens, partner support and comorbid conditions to improve HRQoL of pregnant women with HBV infection.

OBJECTIVE: Data on homocysteine (Hcy) status and its determinants are limited among women during pregnancy and postpartum. This cross-sectional study aimed to investigate Hcy levels during pregnancy and postpartum, and to explore the determinants like geographic factor. METHODS: This study was conducted in women at mid-pregnancy, late-pregnancy and postpartum from southern, central and northern China. Approximately 132 women were included in each stratum by the three phases and regions. Plasma Hcy concentrations were assessed using high-performance liquid chromatography (HPLC), with hyperhomocysteinemia defined as > 10.0 µmol/L. Quantile regression was to estimate medians and interquartile ranges ( IQRs), and logistic regression to examine the determinants of hyperhomocysteinemia. RESULTS: For 1,190 women included, the median (IQR) Hcy concentration was 5.66 (4.62, 7.37) μmol/L. The adjusted median in mid-pregnancy, late-pregnancy and postpartum women was 4.75 (4.13, 5.54), 5.72 (4.81, 6.85) and 7.09 (5.65, 8.75) μmol/L, respectively, showing an increasing trend ( P < 0.001). This increasing trend persisted across the three regions. Higher Hcy concentrations were observed in women residing in northern region and those with younger age or lower economic status. A total of 106 (8.9%) women had hyperhomocysteinemia, with a higher prevalence in those residing in northern region (16.0%), or in postpartum women (16.5%). CONCLUSION Hcy levels, varying with geographic region, maternal age and economic status, are increased from mid-pregnancy to late-pregnancy and postpartum, indicating a need to monitor Hcy levels in pregnant and postpartum women to control potential risks related to elevated Hcy levels.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) can result in fatigue and post-exertional malaise; however, whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection exacerbates lower urinary tract symptoms (LUTS) is unclear. This study investigated the association between prenatal SARS-CoV-2 infection and postpartum LUTS. METHODS: A multicenter, retrospective cohort study was conducted at two tertiary hospitals in China from November 1, 2022, to November 1, 2023. Participants were classified into infected and uninfected groups based on SARS-CoV-2 antigen results. LUTS prevalence and severity were assessed using self-reported symptoms and the Incontinence Impact Questionnaire-Short Form (IIQ-7). Pelvic floor muscle activity was measured using electromyography following the Glazer protocol. Group comparisons were performed to evaluate the association of SARS-CoV-2 infection with LUTS and electromyography parameters, with stratified analyses conducted using SPSS version 26.0. RESULTS: Among 3,652 participants (681 infected, 2,971 uninfected), no significant differences in LUTS prevalence or IIQ-7 scores were observed. However, SARS-CoV-2 infection was an independent factor influencing the electromyographic activity of the pelvic floor muscles (mean tonic contraction amplitudes), regardless of delivery mode ( P = 0.001). CONCLUSION Prenatal SARS-CoV-2 infection was not significantly associated with an increased risk of postpartum LUTS but independently altered pelvic floor muscle electromyographic activity, suggesting potential neuromuscular effects.

Based on the theory of "milk-blood homology", the evidence of Shaoze (SI 1) in treatment of postpartum hypogalactia was explored and the clinical application introduced. In traditional Chinese medicine, small intestine meridian and the functions of small intestine are extensively involved in the procedure of milk formation, i.e. transformation, transportation and connection. Shaoze (SI 1) communicates the meridians of hand-taiyang and hand-shaoyin. It enhances the connection of the small intestine with the heart, spleen and stomach. It is the jing-well point for unblocking and moistening to promote the transformation and transportation of qi and blood and improve lactation. This acupoint is specifically characterized as promoting lactation in the small intestine meridian and is valuable considerably in clinical practice of hypogalactia of deficiency pattern/syndrome.

Postpartum visit are maternal and child health services provided by primary care workers at the homes of postpartum women within one week after hospital discharge. However, China currently lacks detailed work guidelines and standardized protocols for such services, making it difficult to effectively assess the competency of postpartum visitors and improve service quality. This study reviewed 24 Chinese and English articles retrieved using a combination of subject and free terms, selected based on inclusion and exclusion criteria. The key components of postpartum visit competency were summarized into 3 dimensions: Health assessment, health education, and communication/coordination. While home visitors were generally capable of performing basic physical examinations and providing health education for mothers and newborns, they often lacked the ability to deliver more specialized maternal and infant care. Factors affecting the effectiveness of postpartum visit services included the personal characteristics, technical skills, and training of the visitors. Strategies to improve competencies involve reforming training methods, enhancing home visit skills, and standardizing procedures. Currently, there is a lack of comprehensive tools to assess postpartum visit competency.

Polymorphic eruption in pregnancy (PEP), formerly known as pruritic urticarial papules and plaques of pregnancy, is a common gestational dermatosis. It rarely manifests in the early trimester of pregnancy and hardly persists in the postpartum period especially in multigravid patients. PEP usually appears late in the third trimester of a first pregnancy, and less frequently in the immediate postpartum period. It occurs almost exclusively in primigravid mothers and is more common in multiple pregnancies.1 2 3 Recurrence in subsequent pregnancies is extremely rare.3 4 The cause of PEP is still unknown, although various theories have been proposed, including increased skin distention, deposition of fetal DNA in skin lesions, high levels of progesterone, and increased progesterone receptor immunoreactivity in patients with PEP.

In order to prevent the maternal immune defenses to the semi-allogeneic fetus, the maternal body will present a special adaptive immune system change represented by acute thymic involution(ATI) during pregnancy, which can be quickly regenerated after delivery. The ATI during pregnancy is related to the level of sex hormones, which is mainly caused by progesterone. Pregnancy-induced ATI is manifested as the continuous shrinkage of thymus volume, especially the cortex, and the wrinkle and phagocytosis of the subcapsular cortical thymic epithelial cells(cTECs), while other thymic epithelial cells(TECs) remain unchanged. The postpartum thymus is regenerated by the co-mediation of forkhead box N1(FOXN1) as well as its target genes chemokine(C-C motif) ligand 25(CCL25), chemokine(C-X-C motif) ligand 12(CXCL12), δ-like ligand 4(DLL4), cathepsin L(CTSL), and serine protease 16(PRSS16). Once the postpartum thymus is poorly repaired, immune dysfunction of the maternal body and several puerperal diseases will be induced, seriously endangering the survival of the mother and the newborn. In traditional Chinese medicine(TCM), Qi and blood are the cornerstone of pregnancy, and the thymus plays a key role in regulating Qi and blood. The deficiency of Qi and blood during pregnancy and childbirth is closely related to the abnormal ATI during pregnancy and the poor regeneration of the postpartum thymus. Based on this theory, TCM has profound academic ideas and rich clinical experience in postpartum recuperation. Based on the systematic description of the mechanism of ATI regeneration during pregnancy, as well as data mining and analysis of two classic gynecological works of TCM, Wan's Gynecology and Fu Qing-zhu's Treatise on Gynecology, this study found that the commonly used TCM for postpartum included Angelicae Sinensis Radix, Ginseng Radix et Rhizoma, Glycyrrhizae Radix et Rhizoma, and Chuanxiong Rhizoma. Among them, Ginseng Radix et Rhizoma, Angelicae Sinensis Radix, and Chuanxiong Rhizoma are high-frequency TCMs with positive effects on postpartum recovery.However, the mechanism of these TCMs in promoting postpartum thymus regeneration needs further investigation.

Objective: To analyze the incidence and related factors of drug resistance in HIV-infected pregnant and postpartum women in some areas of three western provinces of China from 2017 to 2019. Methods: From April 2017 to April 2019, face-to-face questionnaires and blood sample testing were conducted in all health care institutions providing maternal and perinatal care and midwifery-assisted services in 7 prevention of mother-to-child transmissi project areas in Xinjiang, Yunnan and Guangxi provinces/autonomous regions. Information was collected during the perinatal period and viral load, CD4⁺T lymphocytes and drug resistance genes were detected at the same time. The multivariate logistic regression model was used to analyze the relationship between different factors and drug resistance in HIV-infected pregnant and postpartum women. Results: A total of 655 HIV-infected pregnant and postpartum women were included in this study. The incidence of drug resistance was 3.4% (22/655), all of whom were cross-drug resistant. The rate of low, moderate and high drug resistance was 2.1% (14/655), 1.2% (8/655) and 0.8% (5/655), respectively. The drug resistance rate in the people who had previously used antiviral drugs was 1.9% (8/418), and the drug resistance rate in the people who had not used drugs was 5.9% (14/237). The NNRTI drug resistance accounted for 2.8% (18/655) and the NRTI drug resistance rate was 2.5% (16/655). The multivariate logistic regression model showed that the risk of HIV resistance was lower in pregnant women who had previously used antiviral drugs (OR=0.32, 95%CI: 0.11-0.76). Conclusion: Strengthening the management of antiviral drug use and focusing on pregnant and postpartum women who have not previously used antiviral drugs can help reduce the occurrence of drug-resistant mutations. Personalized antiviral therapy should be considered to achieve viral inhibition effects in clinical practice.

To explore the clinical features and influencing factors of first-onset neuromyelitis optica spectrum disease (NMOSD) within 1 year after delivery. A single center, observational cohort study was used to retrospectively analyze 12 patients with first-onset NMOSD within 1 year after delivery hospitalized in the Department of Neurology of Beijing Tong Ren Hospital from June 2015 to June 2018(short as the postpartum onset group). 12 patients with first-onset NMOSD without 1 year after delivery hospitalized in our department during the same period were selected (short as the control group). The results showed the next recurrence interval in the postpartum onset group was longer than the control group [the postpartum onset group: (6.1±3.5) years, the control group: (1.6±1.5) years, t=3.622,P=0.005], the times of relapses were less than the control group [the postpartum onset group: (1.8±1.4) times, the control group:4.0 (3.0, 7.3) times, Z=-3.122,P=0.002], and expanded disability status scale (EDSS) of the last follow-up was lower than the control group [the postpartum onset group: 3.0(2.3, 3.9), the control group: 4.5(4.0, 6.0), Z=-3.358,P=0.001] with statistically significant differences. The recurrence rates of 1 year, 3 years and 5 years in the postpartum onset group (0%, 16.7%, 33.3%) were lower than control group (58.3%, 83.3%, 91.7%) with statistically significant differences (χ²=8.000,P=0.014;χ²=10.667,P=0.003; χ²=8.711,P=0.009). After the second delivery, the recurrence rate in postpartum onset group was 100% (n=3) and in control group was 50%(n=2), but the difference was not statistically significant (χ²=2.100,P=0.429). In the postpartum onset group, combination of autoimmune disease was consistent with positive in serum AQP-4 antibody moderately (Kappa=0.5, P=0.046). Positive in other autoimmune antibodies were consistent with positive in serum AQP-4 antibody moderately (Kappa=0.5, P=0.046). Combination of autoimmune disease were consistent with positive in serum other autoimmune antibodies well (Kappa=0.667, P=0.021). In conclusion, the first-onset NMOSD within 1 year after delivery have longer next recurrence interval, less times of relapses, lower relapse rate, better long-term prognosis of central nervous system, and they have trend to suffering from recurrent after the second delivery. For the females, combined with autoimmune disease or autoimmune antibody, who are ready for pregnancy, could detect serum AQP-4; if serum AQP-4 positive, they are recommended to prevent the occurrence of NMOSD after delivery.
