BACKGROUND
Endometrial cancer is a kind of gynaecological cancer. S100A2 is a newfound biomarker to diagnose endometrial cancer. This study was to investigate the role of S100A2 on regulating migration and invasion of endometrial cancer.
METHODS
The mRNA and protein levels of S100A2 were obtained by quantitative real-time polymerase chain reaction, immunohistochemistry and western blot methods. Cell viability was measured by the Cell Counting Kit-8 assay. Cell migration and invasion were quantified using transwell assays. Western blot assay was conducted to quantify protein expressions of epithelial to mesenchymal transition-related proteins (N-cadherin and E-cadherin). Furthermore, tumour formation experiments were performed to evaluate the role of S100A2 on tumour xenografts.
RESULTS
S100A2 was significantly up-regulated in endometrial cancer tissues. Knockdown of S100A2 inhibited cell viability, migration and invasion of endometrial cancer cells. Meanwhile, STING pathway was activated by the inhibited S100A2. STING inhibitor C-176 significantly reversed the effects of S100A2 knockdown on aggressive behaviours of endometrial cancer cells. Inhibition of S100A2 dramatically suppresses the tumour growth .
CONCLUSIONS
S100A2 functions as an oncogene in endometrial cancer. Targeting S100A2 may be a promising therapeutic method to treat endometrial carcinoma.

BACKGROUND
Viral diarrhea is one of the major causes of morbidity and mortality in children. This study aimed to conduct etiological surveillance of viral diarrhea in Zhangzhou city, Fujian province, China, from 2017 to 2019 to identify the prevalence, distribution, and characteristics of viral pathogens causing gastrointestinal infections in the region.
METHODS
Stool samples were collected from patients with acute diarrhea in Zhangzhou city, Fujian province, China, from 2017 to 2019. Rotavirus, norovirus, astrovirus, and adenovirus were detected using fluorescence immunochromatography assay.
RESULTS
Of the total 5,627 samples that were collected, at least one of the viruses (rotavirus, norovirus, astrovirus and adenovirus) was found to be positive in 1,422 samples. Rotavirus, norovirus, astrovirus, and adenovirus, were detected in 53.73, 16.68, 15.52, and 14.97%, respectively. Mixed infections were determined in 17.65% of the positive samples. The predominant mixed infections observed were a combination of norovirus and astrovirus, followed by rotavirus and norovirus, and rotavirus and astrovirus. The highest positive rate was observed in the 12-23-month group for rotavirus and adenovirus, while a significantly higher positive rate was observed for norovirus and astrovirus in the 6-11-month group.
CONCLUSION
These findings from this etiological surveillance highlight the significant burden of viral diarrhea in Zhangzhou city, with rotavirus being the predominant pathogen. The identification of common mixed infections provides insights into the complex nature of viral diarrhea transmission. Target interventions and public health strategies should be implemented, particularly during the winter and spring seasons, to prevent and control the spread of viral pathogens causing gastrointestinal infections in this region.

Meta-Analysis Comparative Study
Acute appendicitis is the most common surgical emergency in pregnant women. There has been a wide variance in clinical practice worldwide, with some favoring an antibiotic-only approach while others prefer surgery as the first-line management. Therefore, we designed the current analysis to synthesize the available evidence on the efficacy and safety of antibiotics versus surgery management. We searched PubMed, Scopus, EuropePMC, and Cochrane Central from March 4, 1904 until November 25, 2022, to look for studies comparing antibiotics and surgery in pregnant patients with acute appendicitis. We only included studies that provided a comparison between the two treatments. We included preterm delivery, fetal loss, maternal death, and complications as outcomes. The results were compared using an odds ratio and 95% confidence interval. We also performed a sensitivity analysis by excluding studies with a serious risk of bias. We included five non-randomized studies for the analysis. We found that patients in the antibiotic group had a lower risk of preterm labor (OR 0.63 [95% CI 0.43-0.92]; p 0.02) but a higher risk of complications (OR 1.79 [95% CI 1.19-2.69]; p 0.005). We did not find any difference in the other outcomes. The increased risk of complications should caution clinicians about using antibiotics as the first-line management. More studies are required to identify patients who would benefit the most before antibiotics could be adopted as a treatment for acute appendicitis in pregnant patients.

BACKGROUND
In vitro fertilization is the most used assisted reproductive technology in the United States that is increasing in efficiency and in demand. Certain states have mandated coverage that enable individuals with low income to undergo in vitro fertilization treatment.
OBJECTIVE
This study aimed to evaluate if socioeconomic status has an impact on the perinatal outcomes in in vitro fertilization pregnancies. We hypothesized that with greater coverage there may be an alleviation of the financial burden of in vitro fertilization that can facilitate the application of evidence-based practices.
STUDY DESIGN
This was a retrospective, population-based, observational study that was conducted in accordance with the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample database over the 6-year period from 2008 to 2014 during which period 10,000 in vitro fertilization deliveries were examined. Maternal outcomes of interest included preterm prelabor rupture of membranes, preterm birth (ie, before 37 weeks of gestation), placental abruption, cesarean delivery, operative vaginal delivery, spontaneous vaginal delivery, maternal infection, chorioamnionitis, hysterectomy, and postpartum hemorrhage. Neonatal outcomes included small for gestational age neonates, defined as birthweight <10th percentile, intrauterine fetal death, and congenital anomalies.
RESULTS
Our study found that the socioeconomic status did not have a statistically relevant effect on the perinatal outcomes among women who underwent in vitro fertilization to conceive after adjusting for the potential confounding effects of maternal demographic, preexisting clinical characteristics, and comorbidities.
CONCLUSION
The literature suggests that in states with mandated in vitro fertilization coverage, there are better perinatal outcomes because, in part, of the increased use of best in vitro fertilization practices, such as single-embryo transfers. Moreover, the quality of medical care in states with coverage is in the highest quartile in the country. Therefore, our findings of equivalent perinatal outcomes in in vitro fertilization care irrespective of socioeconomic status possibly suggests that a lack of access to quality medical care may be a factor in the health disparities usually seen among individuals with lower socioeconomic status.

BACKGROUND
Hypertensive disorders of pregnancy are increasing in prevalence and a leading cause of early postpartum readmissions. Stricter blood pressure target goals for treatment of hypertension during pregnancy have recently been proposed, however, the treatment goals for management of postpartum hypertension are less well established.
OBJECTIVE
We sought to evaluate the clinical factors associated with early postpartum readmissions for hypertensive disease and to evaluate blood pressure thresholds associated with these readmissions.
STUDY DESIGN
We conducted a retrospective cohort study of women delivering at a tertiary care center between January 2018 and May 2022 who experienced a hospital readmission for postpartum hypertension or new onset postpartum preeclampsia. Charts were reviewed for clinical and sociodemographic data. Patients with early readmission (<72 hours after discharge) were compared with patients readmitted after 3 days of initial discharge. Data were analyzed using chi-square, Student test, Mann-Whitney test, and logistic regression where appropriate. The value <.05 was considered significant.
RESULTS
During the study period, 23,372 deliveries occurred. Postpartum readmission due to worsening of a known diagnosis of hypertension or new onset postpartum preeclampsia occurred in 1.1% and 0.49% respectively. Patients with early readmission were more likely to have hypertensive disorders of pregnancy as the indication for delivery. Among patients readmitted, 93% had 2 or more systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg, and 73% had blood pressure of either systolic between 130 and 139 mmHg or diastolic between 80 and 89 mmHg within 24 hours before initial discharge. Only 27 patients met criteria (blood pressure ≥160/110 mmHg on >1 vitals check during their hospitalization) to be started on antihypertensives before initial delivery discharge; of those 25 (93%) were discharged with a new prescription for an antihypertensive. After controlling for confounding variables, predischarge blood pressure between 130-140 mmHg/80-90 mmHg (adjusted odds ratio, 2.4 [1.5-4.0]) was associated with an increased likelihood of early readmission.
CONCLUSION
Patients with delivery for hypertensive disorders of pregnancy and predischarge blood pressure ≥140/90 mmHg were less likely to have an early readmission within 3 days of initial discharge, however, patients with predischarge blood pressure 130-139 mmHg/80-89 mmHg were more likely to have an early readmission for hypertensive disorders of pregnancy and postpartum preeclampsia. Further research is indicated to evaluate interventions to prevent postpartum readmission in patients at high risk for persistent hypertension or new onset postpartum preeclampsia.

BACKGROUND
Postpartum readmission is an important indicator of postpartum morbidity. The likelihood of postpartum readmission is highest for Black individuals. However, it is unclear whether the likelihood of postpartum readmission has changed over time according to race/ethnicity. Little is also known about the factors that contribute to these trends.
OBJECTIVE
This study aimed to: (1) examine trends in postpartum readmission by race/ethnicity, (2) examine if prenatal or clinical factors explain the trends, and (3) investigate if racial/ethnic disparities changed over time.
STUDY DESIGN
We examined trends in postpartum readmission, defined as hospitalization within 42 days after birth hospitalization discharge, using live birth and fetal death certificates linked to delivery discharge records from 10,711,289 births in California from 1997 to 2018. We used multivariable logistic regression models that included year and year-squared (to allow for nonlinear trends), overall and stratified by race/ethnicity, to estimate the annual change in postpartum readmission during the study period, represented by odds ratios and 95% confidence intervals. We then adjusted models for prenatal (eg, patient demographics) and clinical (eg, gestational age, mode of birth) factors. To determine whether racial/ethnic disparities changed over time, we calculated risk ratios for 1997 and 2018 by comparing the predicted probabilities from the race-specific, unadjusted logistic regression models.
RESULTS
The overall incidence of postpartum readmission was 10 per 1000 births (17.4/1000 births for non-Hispanic Black, 10/1000 for non-Hispanic White, 7.9/1000 for non-Hispanic Asian/Pacific Islander, and 9.6/1000 for Hispanic individuals). Odds of readmission increased for all groups during the study period; the increase was greatest for Black individuals (42% vs 21%-29% for the other groups). After adjustment for prenatal and clinical factors, the increase in odds was similar for Black and White individuals (12%). The disparity in postpartum readmission rates relative to White individuals increased for Black individuals (risk ratio, 1.68 in 1997 and 1.90 in 2018) and more modestly for Hispanic individuals (risk ratio, 1.02 in 1997 and 1.05 in 2018) during the study period. Asian/Pacific Islander individuals continued to have lower risk than White individuals during the study period (risk ratio, 0.87 in 1997 and 0.82 in 2018).
CONCLUSION
The rate of postpartum readmissions increased from 1997 to 2018 in California across all racial/ethnic groups, with the greatest increase observed for Black individuals. Racial/ethnic differences in the trend were more modest after adjustment for prenatal and clinical factors. It is important to find ways to prevent further increases in postpartum readmission, especially among groups at highest risk.

OBJECTIVE
As a common endocrine and metabolic disorder, polycystic ovary syndrome (PCOS) is mostly associated with an obese phenotype. The present research focuses on the clinical significance of miR-379 in obesity-PCOS and attempts to elucidate its potential mechanisms.
METHODS
Healthy individuals (n = 46), obesity-PCOS (n = 92), and non-obesity PCOS (n = 31) subjects were enrolled. Quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to examine the level of serum miR-379. The receiver operating characteristic (ROC) curve and logistic regressions were applied to reveal the diagnostic significance. Dual luciferase reporters were performed to validate the targeting relationships. And cell count kit (CCK-8) assay was used to detect cell proliferation.
RESULTS
Serum miR-379 was highly expressed in PCOS patients ( < 0.05), in especially obesity-PCOS patients. Higher miR-379 was associated with greater body mass index (BMI), higher bioavailable testosterone (bT), and greater insulin resistance (IR). Additionally, miR-379 was an independent risk factor for the development of obesity-PCOS. The sensitivity of miR-379 in identifying patients with obesity-PCOS from healthy or non-obesity-PCSO patients was 81.52% and 72.83%, and the specificity was 86.96% and 80.65%. Semaphorin 3 A (SEMA3A) was identified as a target of miR-379 and was reduced in the patients with obesity PCOS (P < 0.05). Inhibition of miR-375 reduced KGN proliferation, but this reduction was partially restored by silencing of SEMA3A ( < 0.05).
CONCLUSION
Elevated miR-379 assists the diagnosis of obesity-PCOS and regulates the proliferation of KGN by targeting SEMA3A engaged in disease development.

BACKGROUND
CD46 has been revealed to be a key factor in malignant transformation and cancer treatment. However, the clinical significance of CD46 in cervical cancer remains unclear, and this study aimed to evaluate its role in cervical cancer diagnosis and prognosis evaluation.
METHODS
A total of 180 patients with an initial diagnosis of cervical cancer were enrolled at Taizhou Hospital of Zhejiang Province, China. The plasma levels of soluble CD46 (sCD46) and the expression of membrane-bound CD46 (mCD46) were detected by enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry (IHC), respectively.
RESULTS
CD46 was found to be significantly upregulated in cervical cancer tissues normal tissues, while no CD46 staining was detected in paired adjacent noncancerous tissues. CD46 staining was more pronounced in cancer cells than in stromal cells (in tissues). Moreover, the plasma levels of sCD46 were able to some extent discriminate between cancer patients and healthy women (AUC=0.6847, 95% CI:0.6152-0.7541). Analysis of Kaplan-Meier survival curves revealed that patients with low CD46 expression had slightly longer overall survival (OS) than patients with high CD46 expression in the tumor microenvironment, but no significant difference. Univariate Cox regression analysis revealed that CD46 (=0.034) is an independent risk factor for OS in cervical cancer patients.
CONCLUSION
The present study demonstrated that cervical cancer patients exhibit aberrant expression of CD46, which is closely associated with a poor prognosis, suggesting that CD46 plays a key role in promoting cervical carcinogenesis and that CD46 could serve as a promising potential target for precision therapy for cervical cancer.
