Purpose:
There are many studies regarding the increased relationship between pregnancy outcomes of singleton with endometriosis. However, there was limited evidence of twin pregnancies with endometriosis. This study aimed to compare the pregnancy outcomes and complications in twin pregnancies with or without endometriosis in a single institution.
Materials and Methods:
From January 2011 to July 2022, a retrospective analysis of twin pregnancies was conducted. The endometriosis group included patient with histological or visual confirmation before pregnancy or during cesarean section. Pregnancy outcomes and complications were compared between the two groups.
Results:
Out of 1714 patients examined, 127 (7.4%) were included in the endometriosis group. Maternal body mass index (BMI) was lower in the endometriosis group (p<0.001). There were no significant differences in maternal age, mode of conception, chorionicity, and pregnancy outcomes, such as gestational age at delivery (p=0.835) and the preterm birth rate (p=0.579). The endometriosis group had a significantly higher rate of obstetrical complication: small for gestational age (SGA) <10% (p=0.029). However, after adjustment for BMI, the endometriosis group showed no statistical significance in obstetrical complications, including SGA (adjusted odds ratio, 1.568; 95% confidence interval, 0.984–2.499; p=0.059).
Conclusion
Twin pregnancies with endometriosis were not related to adverse effects on pregnancy outcomes and obstetrical complications. To confirm these outcomes, further large prospective studies are required.

Colorectal cancer is one of the most common cancers globally, ranking second for the number of cancer-related deaths. Metastasis has been reported as the main cause of death in patients with colorectal cancer. Peroxisome proliferator-activated receptor gamma (PPAR-γ) is a transcription factor that functions as a tumor suppressor by inhibiting cellular proliferation, migration, and invasion. In our previous efforts to generate natural product-motivated PPAR-γ ligands, the compounds 1 and 2 were obtained. These compounds activated PPAR-γ and inhibited the migration and invasion of HCT116 colorectal cancer cells, and they were also found to inhibit the epithelial-to-mesenchymal transition, which is a key process in cancer metastasis. Compounds 1 and 2 upregulated expression of the epithelial marker (E-cadherin), and downregulated expression of the mesenchymal marker (N-cadherin) and transcriptional factor (Snail). Therefore, the PPAR-γ agonists 1 and 2 could serve as a valuable model for the study on anti-metastatic leads for the treatment of colorectal cancer.

OBJECTIVE:
The primary objective of this study was to examine the validity and reliability of a semi-quantitative food frequency questionnaire (FFQ) among Chinese children aged 12-17 years.
METHODS:
A semi-quantitative 72-food item FFQ was developed for children aged 12-17 years. The reliability and validity of this FFQ were evaluated against 24-h dietary recalls (24 h DRs) to measure the consumption of foods and nutrients. We administered two FFQs and three DRs to children (N = 160) over a period of 1 month to evaluate the reliability and validity. Reliability was examined by quartile agreement and intraclass correlation coefficients (ICCs), and validity was examined by quartile agreement, Bland-Altman plots and correlation with DRs.
RESULTS:
For reliability, the ICCs between the two FFQs ranged from 0.21 to 0.76 for foods and nutrients, and the quartile agreement ranged from 70.0% to 95.0% in the same or adjacent quartiles. Spearman's correlation coefficients of foods and nutrients between the second FFQ and the 24 h DRs ranged from -0.04 to 0.59. The Bland-Altman plots demonstrated good agreement across the range of intakes among nutrients. The quartile agreement ranged from 50.0% to 100.0%, with infrequent misclassification.
CONCLUSION
The FFQ assessment of dietary intakes demonstrated acceptable relative validity and high reproducibility for Chinese children aged 12-17 years.

OBJECTIVE: To evaluate the feasibility of robotic single-site myomectomy (RSSM). METHODS: Medical records of 355 consecutive women who underwent robotic-assisted laparoscopic myomectomy were retrospectively reviewed. Clinical characteristics were compared between multi-site and single-site systems. After 1:1 propensity score matching for the total myoma number, largest myoma size, and total tumor weight (105 women in each group), surgical outcomes were also compared between the 2 systems. RESULTS: A total of 105 (29.6%) and 250 (70.4%) women underwent RSSM and robotic multi-site myomectomy (RMSM), respectively. RSSM was more commonly performed in women with lower body mass index (21.6 vs. 22.5 kg/m2, P=0.014), without peritoneal adhesions (7.6% vs. 24.8%, P < 0.001), and less (2.6 vs. 4.6, P < 0.001) and smaller (6.3 vs. 7.7 cm, P < 0.001) myomas compared to RMSM. After propensity score matching, the largest myoma size (P=0.143), total myoma number (P=0.671), and tumor weight (P=0.510) were not significantly different between the 2 groups. Although the docking time was significantly longer in the RSSM group (5.1 vs. 3.8 minutes, P=0.005), total operation time was similar between RSSM and RMSM groups (145.9 vs. 147.3 minutes, P=0.856). Additionally, hemoglobin decrement was lower in the RSSM group than in the RMSM group (1.4 vs. 1.8 g/dL, P=0.009). No surgical complication was observed after RSSM, while 1 ileus and 2 febrile complications occurred in women that underwent RMSM (0% vs. 2.9%, P=0.246). CONCLUSION: Although RMSM is preferred for women with multiple large myomas in real clinical practice, RSSM seems to be a feasible surgical method for less complicated cases, and is associated with minimal surgical morbidity.

To investigate the effect and mechanism of miR-498 on Th17 cell differentiation of peripheral blood mononuclear cells (PMBCs) in rheumatoid arthritis (RA) patients, peripheral blood samples were collected from RA patients and healthy controls, respectively. The proportion of CD4IL-17 T cells (Th17 cells) or CD4FOXP3 T cells (Tregs) in T cells and the Th17/Treg ratio were identified by the flow cytometer. The STAT3 and miR-498 expression were measured by Western blot and real-time PCR, respectively. ELISA was used to detect IL-17 concentrations. Luciferase assay was performed to confirm that miR-498 directly targeted the 3' untranslated region (3'UTR) of STAT3 in CD4 T cells. The effect of miR-498 on Th17 cell differentiation was explored by transfection of miR-498 mimic and/or pcDNA-STAT3 into CD4 T cells. In PMBCs of RA patients, the Th17/CD4 T cell ratio was significantly increased, while the Tregs/CD4 T cell ratio was obviously decreased, leading to a higher Th17/Treg ratio. The results showed a reduced miR-498 expression and an increased STAT3 protein expression in PMBCs, and an increased IL-17 concentration in serum of RA patients. In cells transfected with wild-type-STAT3-LU, miR-498 mimic significantly reduced the luciferase activity, STAT3 gene and protein expression, and miR-498 inhibitor had an opposite function. While the miR-498 mimic/inhibitor had no effect on the luciferase activity and STAT3 expression in cells transfected with mutant-STAT3-LU. CD4 T cells transfected with miR-498 mimic had a lower Th17/CD4 T cell ratio and IL-17 concentration, however, transfection of pcDNA-STAT3 reversed the effect of miR-498 mimic on Th17/CD4 T cell ratio and IL-17 concentration. These results suggest that overexpression of miR-498 suppresses Th17 cell differentiation by targeting STAT3 in RA patients.

BACKGROUND: Patients with malignancy are considered to be at high risk of severe pandemic influenza A/H1N1 2009. This study was conducted to identify the severity of pandemic influenza A/H1N1 2009 among patients with malignancy. MATERIALS AND METHODS: Between August 2009 and December 2009, we reviewed clinical data and medical records of 31 patients with malignancy and 63 hospitalized patients without malignancy. RESULTS: Eighty-three patients with laboratory-confirmed pandemic influenza A/H1N1 2009 were admitted. The rate of ICU admission was higher among patients with malignancy (without malignancy 13% vs with malignancy 35%, P=0.024). The mortality rate was higher among patients with malignancy (without malignancy 6% vs with malignancy 25%, P=0.033). Patients using immunosuppressants showed a higher rate of lower respiratory tract infection (83% vs 24%, P=0.013). CONCLUSIONS: Pandemic influenza A/H1N1 2009 in patients with malignancy was more severe than in patients without malignancy.

The interleukin-33 (IL-33)/ST2 pathway has emerged as an intercellular signaling system that participates in antigen-allergen response, autoimmunity and fibrosis. It has been suggested that IL-33/ST2 signaling has been involved in the pathogenesis of rheumatoid arthritis (RA), because IL-33 and its receptor have been specifically mapped to RA synovium. The aim of this study was to determine the levels of IL-33 and sST2 in sera and synovial fluids in patients with RA. The serum level of IL-33 was significantly higher in patients with RA (294.9 +/- 464.0 pg/mL) than in healthy controls (96.0 +/- 236.9 pg/mL, P = 0.002). The synovial fluid level of IL-33 was significantly higher in RA patients than in osteoarthritis patients. The level of serum sST2 was higher in RA patients than in healthy controls (P = 0.042). A significant relationship was found between the levels of IL-33 and IL-1beta (r = 0.311, P = 0.005), and IL-33 and IL-6 (r = 0.264, P = 0.017) in 81 RA patients. The levels of IL-33, sST2 and C-reactive protein decreased after conventional disease-modifying antirheumatic drugs treatment in 10 patients with treatment-naive RA. Conclusively, IL-33 is involved in the pathogenesis of RA and may reflect the degree of inflammation in patients with RA.

Objective: To investigate the effect of tumor necrosis factor (TNF)-alpha on the production of macrophage migration inhibitory factor (MIF), which might have important roles in the immune mediated inflammatory response of Behcet's syndrome. Methods: Sixty two patients with Behcet's syndrome and thirty healthy controls were included in this study. The concentrations of TNF-alpha in sera were determined by enzyme-linked immunosorbent assay (ELISA). Peripheral blood mononuclear cells (PBMCs) from eleven patients with Behcet's syndrome were cultured for 48 hours with various concentration of TNF-alpha. The concentrations of MIF in sera and culture supernatants were determined by ELISA. Results: Serum levels of TNF-alpha were significantly higher in patients with Behcet's syndrome than in healthy controls. TNF-alpha dose-dependently increased MIF production from PBMCs in patients with Behcet's syndrome. Serum levels of TNF-alpha tended to correlate with serum levels of MIF, although did not reach statistical significance. Conclusion: Upregulation of MIF production by increased levels of TNF-alpha in patients with Behcet's syndrome might be related to the pathogenesis of Behcet's syndrome.

OBJECTIVEChildhood absence epilepsy (CAE) is one of the most frequently recognized syndromes among the idiopathic generalized epilepsies (IGEs). It is considered to be a hereditary disease. The possible inheritance pattern of CAE is polygenic. The genes responsible for CAE, however, have not yet been identified. The aim of this study was to further investigate based on the authors' recent work whether or not T-type calcium channel gene-CACNA1H is a susceptibility gene to childhood absence epilepsy.
METHODSThe authors conducted the mutation screening of the exons 6-12 and the nearby partial introns of the CACNA1H gene using the method of direct sequencing of PCR products in 48 newly found CAE patients.
RESULTSThe authors found 13 single nucleotide polymorphisms (SNPs). They also found 4 mutations which only existed in CAE patients. Both G773D and H515Y mutations were heterozygous. The mutation of H515Y has never been reported previously. The patient inherited the mutation from his mother. The authors found two CAE patients with the mutation of G773D previously. This is the third time that the authors found one more CAE family with this G773D mutation, and the patient with the mutation G773D inherited the mutation from his father.
CONCLUSIONT-type calcium channel gene-CACNA1H might be a susceptibility gene to childhood absence epilepsy.
