RESUMEN
Adhesions arising from gynecologic surgeries and cesarean sections pose substantial clinical, social, and economic challenges, leading to issues like pelvic pain, infertility, bowel obstruction, and recurring surgeries. Preventing adhesions is a pressing unmet need, hindered by difficulties in assessing postoperative adhesions and understanding barriers. To bridge adhesion prevention gaps, statements on clinical practices were synthesized to present Asia-Pacific expert perspectives on gynecologic surgery and cesarean section adhesion prevention. An expert panel of eight physicians from various healthcare settings in the Asia-Pacific region was convened and a comprehensive literature search on topics related to adhesion prevention in gynecologic surgeries and cesarean sections was performed. Information from full-text publications was used to develop draft consensus statements, with each statement assigned the highest available evidence level based on a systematic literature review and graded using the Oxford Center for Evidence-based Medicine criteria. A modified Delphi process, involving two rounds of online voting and discussions with an extended group of 109 experts, was employed to reach a consensus on six topics related to adhesion barriers. A set of 15 consensus statements were synthesized. Key topics include adhesion incidence in Asia, cesarean section complications, barrier application status, adhesion formation and prevention, absorbable barriers' effectiveness, recommendations, and future considerations. The statements provide guidance for healthcare professionals, especially in the Asia-Pacific region, to tackle the challenges posed by postoperative adhesions and improve patient outcomes. Further research is needed to enhance understanding and prevention of adhesions in this region.
RESUMEN
Gestational diabetes mellitus (GDM) is a common pregnancy disorder associated with an increased risk of pre-eclampsia and macrosomia. Recent research has shown that the buildup of excess lipids within the placental trophoblast impairs mitochondrial function. However, the exact lipids that impact the placental trophoblast and the underlying mechanism remain unclear. GDM cases and healthy controls were recruited at Kaohsiung Medical University Hospital. The placenta and cord blood were taken during birth. Confocal and electron microscopy were utilized to examine the morphology of the placenta and mitochondria. We determined the lipid composition using liquid chromatography-mass spectrometry in data-independent analysis mode (LC/MSE). In vitro studies were carried out on choriocarcinoma cells (JEG3) to investigate the mechanism of trophoblast mitochondrial dysfunction. Results showed that the GDM placenta was distinguished by increased syncytial knots, chorangiosis, lectin-like oxidized low-density lipoprotein (LDL) receptor-1 (LOX-1) overexpression, and mitochondrial dysfunction. Lysophosphatidylcholine (LPC) 16:0 was significantly elevated in the cord blood LDL of GDM patients. In vitro, we demonstrated that LPC dose-dependently disrupts mitochondrial function by increasing reactive oxygen species (ROS) levels and HIF-1α signaling. In conclusion, highly elevated LPC in cord blood plays a pivotal role in GDM, contributing to trophoblast impairment and pregnancy complications.
RESUMEN
Sugar-sweetened beverages (SSB) are previously reported to jeopardize maternal fetal health, most well-known for gestational diabetes, childhood obesity, and cognitive impairment. Although warnings and diet recommendations urge pregnant women to consume less SSB, there is no noticeable difference in their behavior. How and why reproductive women change their SSB consumption patterns were not investigated previously. Our study aims to investigate beverage consumption patterns and how these patterns change in pregnancy in the context of substance use disorder (SUD). We invited all pregnant women visiting the clinic to answer a structured 20-min questionnaire every trimester during the regular antennal visit. At the end of the study, 337 pregnant women aged over 20 participated. A total of 301 responses entered for final analysis, with a response rate of 89.3%. Our finding showed those with high DSM-5-TR scores reduced SSB intake after becoming pregnant, while those with mild or low DSM-5-TR scores increased SSB intake after becoming pregnant. The top 3 factors related to their SSB consumption were "use despite of known health hazard (n = 133)", "increased desire to drink (n = 88)", and "excessive time spent on seeking SSB (n = 85)". The least reported factors were in the domains of social impairment (ranging from n = 3 to n = 26), pharmacologic effects (i.e., tolerance (n = 24) and withdrawal (n = 70). When participants reduced SSB consumption after becoming pregnant, their choice of beverages largely shifted to sugarless beverage but not much plain water. The result provided new insights in deciphering pregnant women's psychomotor factors for SSB intake, which served as useful references for making clinical or even public health recommendations.

Stomach cancer has a high mortality, which is partially caused by an absence of suitable biomarkers to allow detection of the initiation stages of cancer progression. Thus, identification of critical biomarkers associated with gastric cancer (GC) is required to advance its clinical diagnoses and treatment. Recent studies using tracing models for lineage analysis of GC stem cells indicate that the cell fate decision of the gastric stem cells might be an important issue for stem cell plasticity. They include leucine-rich repeat-containing G-protein-coupled receptor 5 (Lgr5+), Cholecystokinin receptor 2 (Cckr2+), and axis inhibition protein 2 (Axin2+) as the stem cell markers in the antrum, Trefoil Factor 2 (TFF2+), Mist1+ stem cells, and Troy+ chief cells in the corpus. By contrast, Estrogen receptor 1 (eR1), Leucine-rich repeats and immunoglobulin-like domains 1 (Lrig1), SRY (sex determining region Y)-box 2 (Sox2), and B lymphoma Mo-MLV insertion region 1 homolog (Bmi1) are rich in both the antrum and corpus regions. These markers might help to identify the cell-lineage identity and analyze the plasticity of each stem cell population. Thus, identification of marker genes for the development of GC and its environment is critical for the clinical application of cancer stem cells in the prevention of stomach cancers.
RESUMEN
Cryptocaryone (CPC) is a bioactive dihydrochalcone derived from Cryptocarya plants, and its antiproliferation was rarely reported, especially for ovarian cancer (OVCA). This study aimed to examine the regulation ability and mechanism of CPC on three histotypes of OVCA cells (SKOV3, TOV-21G, and TOV-112D). In a 24 h MTS assay, CPC showed antiproliferation effects to OVCA cells, i.e., IC50 values 1.5, 3, and 9.5 µM for TOV-21G, SKOV3, and TOV-112D cells. TOV-21G and SKOV3 cells showed hypersensitivity to CPC when applied for exposure time and concentration experiments. For biological processes, CPC stimulated the generation of reactive oxygen species and mitochondrial superoxide and promoted mitochondrial membrane potential dysfunction in TOV-21G and SKOV3 cells. Apoptosis was detected in OVCA cells through subG1 accumulation and annexin V staining. Apoptosis signaling such as caspase 3/7 activities, cleaved poly (ADP-ribose) polymerase, and caspase 3 expressions were upregulated by CPC. Specifically, the intrinsic and extrinsic apoptotic caspase 9 and caspase 8 were overexpressed in OVCA cells following CPC treatment. Moreover, CPC also stimulated DNA damages in terms of γH2AX expression and increased γH2AX foci. CPC also induced 8-hydroxy-2'-deoxyguanosine DNA damages. These CPC-associated principal biological processes were validated to be oxidative stress-dependent by N-acetylcysteine. In conclusion, CPC is a potential anti-OVCA natural product showing oxidative stress-dependent antiproliferation, apoptosis, and DNA damaging functions.

There is considerable cellular diversity in the human stomach, which has helped to clarify cell plasticity in normal development and tumorigenesis. Thus, the stomach is an interesting model for understanding cellular plasticity and for developing prospective anticancer therapeutic agents. However, many questions remain regarding the development of cancers in vivo and in vitro in two- or three-dimensional (2D/3D) cultures, as well as the role of Helicobacter pylori (H. p.) infection. Here, we focus on the characteristics of cancer stem cells and their derived 3D organoids in culture, including the formation of stem cell niches. We define the conditions required for such organoid culture in vitro and examine the ability of such models for testing the use of anticancer agents. We also summarize the signaling cascades and the specific markers of stomach-cancer-derived organoids induced by H. p. infection, and their stem cell niches.

Antimicrobial peptides (AMPs) are known to play an important role in natural immunity. Moreover, the diverse biological activities of AMPs showed great potency in treating many diseases. Thus, in this study, we used an AMP, that is, pardaxin, from a marine fish (Pardachirus marmoratus), which has been reported to possess antibacterial and antitumor activities. We first investigated the mechanisms of pardaxin in promoting osteogenic differentiation in vitro and in vivo. As per our data, it was determined that pardaxin could stimulate bone morphogenetic protein-2 (BMP-2) and downstream cascade. The activation of BMP-2 could further induce the phosphorylation of Akt and extracellular signal-regulated kinase (ERK). Additionally, the activation of p-Akt and p-ERK could prompt the elevation and translocation of runt-related transcription factor 2 (runx-2), which is associated with osteoblast differentiation. The translocation of runx-2 initiated transcription and translation of osteogenesis-related markers, including alkaline phosphatase (ALP), osterix, and osteocalcin. Pardaxin significantly facilitated preosteoblast cells in mineralization and reversed dexamethasone- (DM-) induced zebrafish bone formation deficiency by activating the osteogenesis pathway. Therefore, we suggest that pardaxin could be a possible candidate for osteoporosis treatment and a promising therapeutic agent.

The aryl hydrocarbon receptor (AhR) is a ligand-binding protein that responds to environmental aromatic hydrocarbons and stimulates the transcription of downstream phase I enzyme-related genes by binding the cis element of dioxin-responsive elements (DREs)/xenobiotic-responsive elements. Dimethyl sulfoxide (DMSO) is a well-known organic solvent that is often used to dissolve phase I reagents in toxicology and oxidative stress research experiments. In the current study, we discovered that 0.1% DMSO significantly induced the activation of the AhR promoter via DREs and produced reactive oxygen species, which induced apoptosis in mouse embryonic fibroblasts (MEFs). Moreover, Jun dimerization protein 2 (Jdp2) was found to be required for activation of the AhR promoter in response to DMSO. Coimmunoprecipitation and chromatin immunoprecipitation studies demonstrated that the phase I-dependent transcription factors, AhR and the AhR nuclear translocator, and phase II-dependent transcription factors such as nuclear factor (erythroid-derived 2)-like 2 (Nrf2) integrated into DRE sites together with Jdp2 to form an activation complex to increase AhR promoter activity in response to DMSO in MEFs. Our findings provide evidence for the functional role of Jdp2 in controlling the AhR gene via Nrf2 and provide insights into how Jdp2 contributes to the regulation of ROS production and the cell spreading and apoptosis produced by the ligand DMSO in MEFs.

AIM: The study aimed to explore the risk factors for progression to type 2 diabetes in women with gestational diabetes mellitus and the long-term impact of gestational diabetes mellitus on the health of their children. BACKGROUND: The occurrence of gestational diabetes mellitus in women is the strongest predictor of the development of type 2 diabetes in the future. DESIGN: A non-concurrent cohort and case-control study design and the guidelines for STROBE checklist were used for the study. METHODS: We reviewed medical records for the time period from the archives of the hospitals. The short-listed women and their children were invited to participate in a 'Women with gestational diabetes mellitus' research activity from November 2012-February 2016. Blood tests, physiological indicators and demographic questionnaires were applied for data collection. RESULTS: A total of 57 women and 57 children participated in the research activity. The risk factors for progression of gestational diabetes mellitus to type 2 diabetes included education level and the 1-h blood glucose level for the antepartum 100-g oral glucose tolerance test and the 2-h blood glucose level for the postpartum 75-g oral glucose tolerance test. However, these risk factors did not have a significant impact on the body mass index and body fat of the women's children. CONCLUSION: Healthcare providers should adopt a breadth of health education strategies to remind women with gestational diabetes mellitus to be aware of certain risk factors, and to urge them and their children to return for regular follow-up visits. RELEVANCE TO CLINICAL PRACTICE: Identification of the risk factors developing type 2 diabetes can make healthcare units incorporate the postpartum follow-up of gestational diabetes mellitus into their standard protocol and case managers continue to follow-up and manage the health of the women and that of their children to reduce adverse health of them.

Few pharmaceutical agents for slowing Parkinson's disease (PD) progression existed, especially for perimenopause females. The current general medications are mostly hormone replacement therapy and may have some side effects. Therefore, there is an urgent need for a novel treatment for PD. This study examined the possibility of estradiol plus lithium chloride (LiCl), one of the metal halides used as an alternative to salt. We showed that the combination of LiCl and estradiol could enhance neurogenesis proteins GAP-43 and N-myc in the human neuronal-like cells. We also further confirmed the neurogenesis activity in zebrafish. LiCl and LiCl plus estradiol could enhance 6-OHDA-induced upregulation of TGase-2b and Rho A mRNA expression. Besides, LiCl plus estradiol showed a synergic effect in anti-apoptotic activity. LiCl plus estradiol protected SH-SY5Y cells and zebrafish against 6-OHDA-induced damage on neurons than LiCl or estradiol alone groups via p-P38, p-Akt, Bcl-2, and caspase-3 cascade. The potential for developing this combination as a candidate treatment for PD is discussed.
RESUMEN
The association among sugar sweetened beverages (SSB) consumption, addiction and depression in adults, children and adolescents is widely reported. Dieting patterns during pregnancy is complicated by maternal fetal concerns. Specifically, restrained use of SSB might be potentially a source of perinatal distress. The current study modified diagnostic criteria for Substance Use Disorder (SUD) in Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), into SSB-specific questions to assess SSB use tendency. Edinburgh Postpartum Depression Scores (EPDS) is used to assess maternal distress during pregnancy. One hundred and ninety-six consecutive pregnant women receiving antenatal care at Kaohsiung Medical University Hospital were invited to participate in this study. In the first trimester, 46.6% of women had none or 1 DSM-5 symptom, 27.0% had 2-3 symptoms, while 26.4% had ≥ 4 symptoms. The mean numbers of DSM-5 symptoms in each trimester were found to be 2.5 ± 2.25, 2.6 ± 2.45, 2.4 ± 2.43 for the first, second and third trimester, respectively, p = 0.750. While EPDS score showed no difference among DSM-5 symptoms 0-1, 2-3 and ≥ 4 groups in the first trimester (8.1 ± 4.59, 8.4 ± 5.00, 8.8 ± 4.82, p = 0.343), women with ≥ 4 DSM-symptoms was found significantly higher EPDS scores than those with < 4 DSM-symptoms in the second (7.2 ± 4.81, 7.7 ± 4.98, 8.8 ± 4.33, p = 0.030) and third trimester (6.8 ± 5.00, 7.2 ± 4.63, 8.7 ± 5.24, p = 0.019). The relationship remained significant after adjusting for covariates including actual SSB amount consumed (adjusted ß = 0.25 with 95% confident interval (CI) 0.04-0.45 and 0.21 with 95% CI 0.04-0.38 for the second and third trimesters, respectively). Overall, the study is the first to characterize the positive relationship between SSB use tendency and antenatal distress in pregnancy, independent of actual SSB amount consumed. The observational nature of the study design precludes inferences of its underlying socio-psychomotor mechanisms, although restrained SSB use in pregnancy is suspected to contribute. The novel employment of modified SSB-specific DSM-5 scores and EPDS in this setting is feasible and further validation is promising. With better understanding and awareness, pregnant women with increased SSB use tendency should be properly counseled with special attention to their mental state.

BACKGROUND: The cerebellum is the sensitive region of the brain to developmental abnormalities related to the effects of oxidative stresses. Abnormal cerebellar lobe formation, found in Jun dimerization protein 2 (Jdp2)-knockout (KO) mice, is related to increased antioxidant formation and a reduction in apoptotic cell death in granule cell progenitors (GCPs). Here, we aim that Jdp2 plays a critical role of cerebellar development which is affected by the ROS regulation and redox control. OBJECTIVE: Jdp2-promoter-Cre transgenic mouse displayed a positive signal in the cerebellum, especially within granule cells. Jdp2-KO mice exhibited impaired development of the cerebellum compared with wild-type (WT) mice. The antioxidation controlled gene, such as cystine-glutamate transporter Slc7a11, might be critical to regulate the redox homeostasis and the development of the cerebellum. METHODS: We generated the Jdp2-promoter-Cre mice and Jdp2-KO mice to examine the levels of Slc7a11, ROS levels and the expressions of antioxidation related genes were examined in the mouse cerebellum using the immunohistochemistry. RESULTS: The cerebellum of Jdp2-KO mice displayed expression of the cystine-glutamate transporter Slc7a11, within the internal granule layer at postnatal day 6; in contrast, the WT cerebellum mainly displayed Sla7a11 expression in the external granule layer. Moreover, development of the cerebellar lobes in Jdp2-KO mice was altered compared with WT mice. Expression of Slc7a11, Nrf2, and p21Cip1 was higher in the cerebellum of Jdp2-KO mice than in WT mice. CONCLUSION: Jdp2 is a critical regulator of Slc7a11 transporter during the antioxidation response, which might control the growth, apoptosis, and differentiation of GCPs in the cerebellar lobes. These observations are consistent with our previous study in vitro.

OBJECTIVE: There are few nationwide studies regarding the long-term analysis of cervical cancer patients in Taiwan. Thus, this study aimed to evaluate medical service utilization, and survival among cervical cancer patients initially diagnosed with or without anxiety and/or depressive disorders. MATERIALS AND METHODS: This was a retrospective longitudinal study using data from the National Health Insurance Research Database from 1996 to 2010. The study subjects were cervical cancer patients identified by ICD-9-CM codes 180.X, while subjects with anxiety and/or depressive disorders were identified using the following codes: 300.0X-300.9X (minus 300.4X) for anxiety disorder, and 296.2X, 296.3X, 300.4, and 311.X for depressive disorder. The cervical patients with anxiety or/and depression disorder were classified as anxiety/depression (AD) group or the non-disorder (ND) group. Propensity score matching (PSM) was used to adjust for differences between the AD and ND groups. T-tests were used to evaluate differences in medical utilization and the Kaplan-Meier method was used to evaluate survival conditions between the two groups. Statistical analyses were performed using SPSS Statistics 20.0. RESULTS: A total of 3664 patients were identified, with 862 (23.5%) having anxiety, 149 (4.1%) with depression, and 349 (9.5%) having both anxiety and depression. In total, 1360 cervical cancer patients had anxiety/depression disorders. After PSM, the AD group had significantly more outpatient department (OPD) visits than the ND group (p < 0.001) but the survival status was better in the AD group than the ND group (p < 0.001). CONCLUSIONS: Cervical cancer patients with anxiety/depression disorders visited the OPD more frequently than those without anxiety/depression disorders but had better survival status. Gynecologists should also consider cancer patients' mental status during follow-up, referring patients to psychiatric professionals for appropriate psychiatric care if appropriate.

The pleiotropic behavior of mesenchymal stem cells (MSCs) has gained global attention due to their immense potential for immunosuppression and their therapeutic role in immune disorders. MSCs migrate towards inflamed microenvironments, produce anti-inflammatory cytokines and conceal themselves from the innate immune system. These signatures are the reason for the uprising in the sciences of cellular therapy in the last decades. Irrespective of their therapeutic role in immune disorders, some factors limit beneficial effects such as inconsistency of cell characteristics, erratic protocols, deviating dosages, and diverse transfusion patterns. Conclusive protocols for cell culture, differentiation, expansion, and cryopreservation of MSCs are of the utmost importance for a better understanding of MSCs in therapeutic applications. In this review, we address the immunomodulatory properties and immunosuppressive actions of MSCs. Also, we sum up the results of the enhancement, utilization, and therapeutic responses of MSCs in treating inflammatory diseases, metabolic disorders and diabetes.

AIM: To examine female youth's intentions for safe sex with the relationship partners based on the extended theory of planned behaviour (TPB) model and explore the direct and indirect impact of parent-child communication about sex, peer interaction related to sexual issues, and exposure to sexually explicit materials on female youth's safe sexual behaviour intentions. DESIGN: A non-experimental, cross-sectional research design. METHODS: A convenience sampling was employed for data collection and 731 female youth aged 15-24 years old were recruited in 2013-2014. An anonymous, self-report structured questionnaire was used as a research instrument to collect participants' basic information and measure the internal and additional variables in the extended TPB model. RESULTS: The extended TPB model explained 42-45% of the total variance. Perceived behavioural control (PBC) and subjective norms had a positive effect on female youth's intentions for contraceptive use, condom use, and dual use with relationship partner; PBC was found to have the greatest influence. Among the additional variables in the extended TPB model, more parent-child communication about sex was found to lead to more positive dual use intentions. More peer interaction related to sexual issues was found to lead to less dual use intentions. CONCLUSIONS: To improve female youth's sexual health, the priorities are to reinforce their PBC and subjective norms and enhance parent-child communication about sex. Future efforts should strengthen sex education in families and schools and shape a social environment that facilitates safe sex. IMPACT: The extended TPB model can successfully predict female youth's safe sexual behaviour intentions. Empowering female youth to establish a sense of subjectivity and awareness of being a mature individual with physical autonomy, is importance for their sexual health.

Parkinson's disease (PD) is one of the most widespread neurodegenerative diseases. However, the currently available treatments could only relieve symptoms. Novel therapeutic targets are urgently needed. Several previous studies mentioned that protein tyrosine phosphatase 1B (PTP1B) acted as a negative regulator of the insulin signal pathway and played a significant role in the inflammation process. However, few studies have investigated the role of PTP1B in the central nervous system. Our study showed that suramin, an inhibitor of PTP1B, could improve neuronal damage. It could significantly attenuate the interferon-gamma-induced upregulation of proinflammatory cytokines, including inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB). It enhanced M2 type microglia markers, such as arginase-1 and Ym-1 in BV2 murine microglial cells. PTP1B inhibition also reversed 6-hydroxydopamine- (6-OHDA-) induced downregulation of phospho-cAMP response element-binding protein (p-CREB) and brain-derived neurotrophic factor (BDNF) in SH-SY5Y cells. Besides, we knocked down and overexpressed PTP1B in the SH-SY5Y cells to confirm its role in neuroprotection. We also verified the effect of suramin in the zebrafish PD model. Treatment with suramin could significantly reverse 6-OHDA-induced locomotor deficits and improved tyrosine hydroxylase (TH) via attenuating endoplasmic reticulum (ER) stress biomarkers. These results support that PTP1B could potentially regulate PD via antineuroinflammation and antiapoptotic pathways.
RESUMEN
OBJECTIVE: According to World Health Organization's Jungner and Wilson criteria for competent screening programs, routine antenatal ultrasound screening is legit and effective to improve both maternal and perinatal outcomes. Health Promotion Administration, Ministry of Health and Welfare in Taiwan followed expert recommendations and started reimbursing one antenatal ultrasonography around mid-second trimester since 1995. However, medical disputes pertaining to examination results grew, while confusions challenged doctors and patients alike. The aim of this study is to assess current use of antenatal ultrasonography for low-risk pregnancies in Taiwan. Specifically, the indications, test frequencies, test items, methods of payment, obstetricians' opinions on important scan timing and areas to be improved are surveyed and analyzed. An overview of international antenatal ultrasound practice guidelines are examined and compared to enhance the quality of antenatal ultrasound screening in Taiwan. MATERIALS AND METHODS: From December 2015 to December 2016, 925 questionnaires were distributed to all licensed obstetricians registered to Taiwan Association of Obstetrics and Gynecology as well as Taiwan Society of Perinatology. A 10-min self-reporting questionnaire was sent by mail, with stamped return envelopes included. Respondents remained entirely anonymous and disclosed no personal information. Data was collected and analyzed for statistical analysis. RESULTS: Most hospitals are well equipped with ultrasound machines of 3 or more functions. Eighty-eight percent of the obstetricians in Taiwan perform prenatal ultrasonography in every office visit for their patients, mostly free of charge. Scans at gestational age 15-22 weeks, <10 weeks, 11-14 weeks and 28-32 weeks are polled as the most importance in the order of significance. In general, they perceive the one-time antenatal scan offered by the Health Promotion Administration as for general obstetrics scan but not higher-leveled studies. Patient education and doctor-patient communications are opined as the 2 most important aspects to enhance antenatal ultrasound quality. CONCLUSION: This report is the first of its kind in Taiwan. It could potentially serve as guidance for national health policy innovations in maternal and fetal care, such as increasing frequency of scans, specifications of scan timing, indications and consequences as well as patient education about this screening modality.

PROBLEM: Nausea and vomiting not only cause physical discomfort in pregnant women but also impact their quality of life. BACKGROUND: Few longitudinal studies have been conducted to investigate QOL of women over the course of pregnancy. AIM: To examine the transformation of health-related QOL and related factors among pregnant women with NV during three trimesters. METHODS: A longitudinal research design with convenience sampling was used. A structural questionnaire was used to repeatedly measure the data of 101 pregnant women with NV during the first, second, and third trimesters. A generalized estimating equation (GEE) was used to analyze the collecting data. FINDINGS: The results showed significant differences in symptom distress, prenatal stress, and health-related QOL among the three trimesters in pregnant women with NV (p<0.001). The scores of symptom distress, prenatal stress, and health-related QOL in the first trimester were significantly higher than those in the second and third trimesters (p<0.001). The GEE indicated that the trimester of pregnancy, severity of NV, symptom distress, and prenatal stress were key factors for the transformation of health-related QOL of women with NV during pregnancy. DISCUSSION: The findings of this study are seminal in terms of understanding the relationships between symptom distress, prenatal stress and health-related QOL in pregnant women with NV over the course of a pregnancy. CONCLUSION: This study can serve as a reference for designing interventions (i.e., professional support) for women in different pregnancy stages to improve their health-related QOL during pregnancy.

OBJECTIVE: Ruptured cervical varicose veins can cause significant vaginal bleeding during the third trimester of pregnancy. The etiology is not uncommon, yet receives little discussion in current literature. We here report such a case with complete evaluations, managements and follow ups; while analyzing similar cases published. CASE REPORT: A 34-year-old pregnant woman, gravida 1, presented with sudden onset of painless antepartum hemorrhage at 31+5 weeks of gestation. Speculum examination revealed ruptured cervical varicose veins; further evaluations with transvaginal sonography and magnetic resonance imaging were done to study the extensiveness and characteristics of the lesion. The cervical varices spontaneously regressed by postpartum day 4 and no recurrence was observed in the immediate postpartum follow-up period or in the subsequent pregnancy. CONCLUSION: The case is unique for the lack of association with placenta previa. Cervical varicose veins rupture should be considered for painless vaginal bleeding during the third trimester pregnancy.

OBJECTIVE: This study aims to examine the long-term cardiovascular and cerebrovascular risks in a large cohort of women with past history of preeclampsia and/or eclampsia. MATERIALS AND METHODS: This is a retrospective longitudinal study using National Health Insurance Research Database from 1996 to 2010. We identified 1295 women with preeclampsia and eclampsia. The control group was 5180 pregnant women without preeclampsia/eclampsia, who were matched for age and date of delivery. The incidences of diabetes, dyslipidemia, hypertension and cardiovascular events after pregnancy were identified from medical records after the date of delivery to the date of an event or the end of the study. RESULTS: The median follow-up duration was 9.8 years (interquartile 5.1-12.7 years). The incidences of diabetes, dyslipidemia, hypertension, congestive heart failure and cerebrovascular disease events were significantly greater in women with eclampsia or preeclampsia than those in controls. Eclampsia or preeclampsia increased the risk of diabetes, dyslipidemia, hypertension, congestive heart failure and cerebrovascular disease events (hazard ratio [HR] 3.84 and 5.42, P < 0.0001; HR 2.75 and 3.40, P < 0.0001; HR 6.52 and 7.31, P < 0.0001; HR 9.07, P = 0.0060 and 7.39, P < 0.0001; HR 10.71, P < 0.0001 and 3.47, P = 0.0048, respectively). The survival curves for the development of congestive heart failure and cerebrovascular disease in women with eclampsia/preeclampsia and in control differed significantly (Log-rank test P < 0.0001). From the curve, we can find dramatic increases of congestive heart failure and cerebrovascular disease incidences at roughly 3 years and 10 years since the diagnosis of eclampsia/preeclampsia. CONCLUSIONS: Our study revealed that women with a history of preeclampsia/eclampsia were at increased risks for subsequent diagnoses of diabetes, dyslipidemia, hypertension, congestive heart failure and cerebrovascular disease. Preventive counseling, more vigilant screening and management for the modifiable risks should be provided to the affected women. Clinicians should closely monitor these patients in the first three years postpartum and continuously for up to at least a decade.
