Diagnostic and Predictive Significance of Serum MiR-141-3p in Acute Respiratory Distress Syndrome Patients with Pulmonary Fibrosis.
Pulmonary fibrosis (PF) is the major complication and death-related factor of acute respiratory distress syndrome (ARDS). This study evaluated the significance of miR-141-3p in ARDS and its complication of PF aiming to identify a potential biomarker for screening ARDS and predicting the occurrence of PF. A total of 137 ARDS patients and 69 healthy individuals were enrolled in this study and the serum samples were collected from all participants. ⋯ Additionally, miR-141-3p could discriminate ARDS patients with PF and without PF, and was closely associated with the decreased total lung capacity, carbon monoxide diffusing capacity, and forced vital capacity of ARDS patients with PF. Downregulated miR-141-3p served as a biomarker for ARDS screening disease onset and indicating the severity. Reduced miR-141-3p was also identified as a risk factor for PF in ARDS patients and was associated with the severe progression of PF.

Vasohibin-2-Targeting Therapies for the Treatment of Pancreatic Ductal Adenocarcinoma.
As pancreatic ductal adenocarcinoma (PDAC) is extremely malignant and refractory, therapeutic options for this cancer are anticipated worldwide. We isolated vasohihibin-2 (VASH2) and observed its overexpression in various types of cancer. We then noticed that upregulated expression of VASH2 in patients with PDAC resulted in a conspicuous reduction in the postoperative survival period and further revealed that the abrogation of Vash2 expression in pancreatic cancer cells inhibited its growth and metastasis and augmented tumor infiltration of CD8+ cells in the mouse model. ⋯ VASH2-ASO therapy can be administered at any stage of PDAC. Because of the increase of CD8+ cell infiltration, the combination therapy with immune checkpoint inhibitors may be an attractive option. The VASH2-peptide vaccine therapy may be useful for preventing metastasis and/or recurrence after successful initial treatment.

Gender Differences in the Association between Psychological Distress and Sociability among Older Adult Survivors: Cross-Sectional Survey Four Years after the 2016 Kumamoto Earthquake in Japan.
Mental health deterioration after a disaster is a concern. Individuals' sociability is expected to relate to the risk of this deterioration; however, research focusing on older adults is lacking. We aimed to investigate the relationship between psychological distress and sociability in older adults who survived the 2016 Kumamoto earthquake. ⋯ Moreover, having a family member or friend to consult with was associated with a lower risk of psychological distress, regardless of gender. Gender differences were related to different conditions of social participation and types of social relationships. Enhancing community participation and family relationships among women and social contact with friends among men is essential.

Serum Cell Division Cycle 42 before and after Programmed Death-1 Inhibitor Therapy in Advanced Melanoma Patients: Correlation with Tumor Features, Clinical Response, and Survival.
Cell division cycle 42 (CDC42) mediates immune escape in cancers. This study aimed to investigate linkages of CDC42 with tumor features, treatment response, and survival in advanced melanoma patients receiving programmed death-1 (PD-1) inhibitors. Pre-treatment and post-treatment (after 2 cycles) serum CDC42 of 35 advanced melanoma patients receiving PD-1 inhibitor was assessed by enzyme-linked immunosorbent assay. ⋯ The 12-month PFS rate was 12.5% and 62.0%, and the 12-month OS rate was 42.3% and 88.0% in patients with post-treatment with CDC42 > 700 pg/mL and ≤ 700 pg/mL, accordingly. Furthermore, post-treatment with CDC42 > 700 pg/mL was independently related to PFS [hazard ratio (HR): 2.704, P = 0.029 and OS (HR: 7.749, P = 0.005)]. Elevated CDC42 correlates with advanced TNM, abnormal LDH, worse clinical response, and dismal survival in advanced melanoma patients receiving PD-1 inhibitors.

Fondaparinux Results in Similar Pregnancy Outcomes with Lower Adverse Reaction Rates Compared to Low Molecular Weight Heparin in Chinese Recurrent Miscarriage Women.
Fondaparinux inhibits thrombin generation by inactivating factor Xa, which has the potential to treat recurrent miscarriage (RM). However, more clinical evidence is required to support its application in Chinese women with RM. This research aimed to compare the live birth rate, gestational weeks at delivery, birth weight, Apgar score of newborns, and adverse reaction rates between fondaparinux and low molecular weight heparin (LMWH) in Chinese women with RM. ⋯ It was also observed that gestational weeks at delivery (38.1 ± 1.4 vs. 37.7 ± 1.7 weeks) (P = 0.258), birth weight (2,923.7 ± 355.0 vs. 2,807.8 ± 334.0 g) (P = 0.144), and Apgar score of newborns (9.8 ± 0.5 vs. 9.6 ± 0.8) (P = 0.175) were not different between the fondaparinux cohort and LMWH cohort. Inspiringly, the total adverse reaction rate was reduced in the fondaparinux cohort vs. the LMWH cohort (20.0% vs. 37.9%) (P = 0.036). Fondaparinux results in similar pregnancy outcomes with lower adverse reaction rates compared to LMWH in Chinese women with RM.
