10, 1.38). Adjusting for affective traits completely attenuated the comorbidity associations for hay fever and eczema with GERD, and partly for asthma with GERD. Co-twin control associations attenuated suggesting a shared cause for both GERD and atopic diseases. For example, all twins adjOR 1.32 (95%CI 1.00, 1.74), 0.97 (95% CI 0.76-1.23) and 1.11 (95%CI 0.85-1.45) for self-report asthma, hay fever and eczema with GERD respectively.
GERD is a common comorbidity in adults with asthma, hay fever and/or eczema. We found evidence for shared mechanisms suggesting common underlying causes that may involve affective traits requiring further investigation.

The Fleckvieh cows in the mid-luteal phase (days 8-12, control group) were injected with cloprostenol (PGF analogue), and CL were collected by transvaginal ovariectomy before (days 8-12, control group) and at 0.5, 2, 4, 12, 24, 48 and 64 h after PGF application (n = 5 per group). The mRNA expression was determined by RT-qPCR, the hormone concentrations by enzyme immunoassay and localization by immunohistochemistry. PTGS2 gene expression increased significantly 2 h after PGF application, followed by continuous and significant downregulation afterwards. The PGF tissue concentration increased significantly just after PGF injection and again during structural luteolysis (after 12 h), whereas PGE concentration significantly decreased during structural luteolysis. The FP receptor mRNA decreased significantly at 2 h and again at 12 h after PGF. In contrast, EP4 receptor mRNA increased significantly just after the PGF application (0.5 h). The immunostaining of PGES and PTGS2 on day 15-17 shows numerous positive luteal cells, followed by lower activity afterwards on day 18 (luteolysis). In conclusion, the changes of examined prostaglandin family members in CL tissue after PGF application may be key components of the local mechanisms regulating the cascade of actions leading to functional and subsequent structural luteolysis in the bovine ovary.The current cross-sectional study aimed to extend the literature on childhood adversity by examining the unique associations between potentially traumatic events (PTEs) and a range of mental health concerns, including domain-specific versus comorbid concerns. Participants were 11,877 preadolescents (47.8% female, 15.0% Black, 20.3% Hispanic/Latinx, Mage = 9.5 years) taking part in the Adolescent Brain and Cognitive Development (ABCD) Study® . The Kiddie Schedule for Affective Disorders and Schizophrenia was used to measure PTEs and caregiver- and child-reported mental health concerns. Adjusted odds ratios (aORs) were used for the outcomes of interest. Overall, PTEs were consistently associated with increased odds of experiencing comorbid posttraumatic stress disorder (PTSD), internalizing disorders, and externalizing disorders, significant AORs = 1.34-4.30, after accounting for children's experiences of other PTEs and polyvictimization. In contrast, PTEs were generally not associated with meeting the criteria for diagnoses within only one domain (i.e., internalizing-only or externalizing-only diagnoses). We also found PTEs to be differentially related to the various mental health outcomes. In particular, witnessing domestic violence was consistently associated with children's psychopathology. Other PTEs, such as witnessing community violence, were not associated with children's psychopathology in the final model. Associations between PTEs and mental health concerns did not differ as a function of sex. Overall, the results support the notion that PTEs are associated with comorbid concerns rather than individual disorders. These findings have important implications for the screening of PTEs, continued research on the conceptualization of traumatic stress, and the importance of accounting for comorbidities across mental health domains.
There is a great interest in determining whether the expression of the programmed cell death ligand 1 is correlated with the efficacy of immune checkpoint inhibitors in patients with clear cell renal cell carcinoma; however, primary tumor biopsies can only provide limited information. Therefore, we explored the expression of programmed cell death ligand 1 on circulating tumor cells, which is a potential predictor of therapeutic response.
Circulating tumor cells were isolated from 20 clear cell renal cell carcinoma patients based on cell surface markers targeting clear cell renal cell carcinoma using IsoFlux device, followed by identification according to cell morphology and immunofluorescence studies. Programmed cell death ligand 1 expression status and clinical correlations were also analyzed.
Before treatment with programmed cell death protein 1 inhibitors, circulating tumor cells were detected in all patients, ranging from 1 to 22 (median 7), with 75% (15/20) of the patients having programmed cell de clear cell renal cell carcinoma patients' blood samples, which can potentially be used as an individualized immunotherapy molecular biomarker for real-time exploration.
We showed that the presence of programmed cell death ligand 1 + circulating tumor cells before programmed cell death protein 1 inhibition treatment could be a prognosis predictive factor and that the dynamic changes in circulating tumor cell numbers may be used to monitor the therapeutic response. Our study confirms the possibility of programmed cell death ligand 1 + circulating tumor cell detection in clear cell renal cell carcinoma patients' blood samples, which can potentially be used as an individualized immunotherapy molecular biomarker for real-time exploration.
Despite the widespread use of endoscopic submucosal dissection (ESD) for early gastric cancer, post-ESD bleeding remains a significant problem. Intragastric pH plays an important role in intragastric bleeding. Because gastric acid secretion contributes to intragastric pH, both the presence or absence of Helicobacter pylori infection and the degree of gastric mucosal atrophy may affect bleeding. The present study aimed to clarify the relationship between post-ESD bleeding and the degree of gastric mucosal atrophy based on H.pylori infection status.
We included 8170 patients who underwent ESD for early gastric cancer at 33 hospitals in Japan from November 2013 to October 2016. We analyzed the risk factors contributing to post-ESD bleeding.
There were 3935 H.pylori-positive patients and 4235 H.pylori-negative patients. A nonsevere degree of gastric mucosal atrophy was an independent risk factor for post-ESD bleeding in H.pylori-negative patients (odds ratio 1.51, P=0.007), but not in H.pylori-positive patients (odds ratio 0.91, P=0.600). Further, in H.pylori-negative, but not H.pylori-positive, patients, the rate of post-ESD bleeding increased in a stepwise manner for patients continuing antithrombotic drug use, patients who withdrew antithrombotic drug use, and antithrombotic drug nonusers.
Nonsevere gastric mucosal atrophy was a risk factor for post-ESD bleeding in early gastric cancer in H.pylori-negative patients but not in H.pylori-positive patients.

The aim of this study is to evaluate long-term in vivo stability of dental implants stabilized at time of placement in oversized osteotomies with a novel, self-setting, mineral-organic bone adhesive.
Canine (26) mandibular teeth were removed, and three oversized osteotomies prepared bilaterally. Implants were placed with either adhesive, particulate xenograft, or with blood clot filling the implant/osteotomy gaps. Removal torque and histology were assessed.
The adhesive provided significant and clinically relevant immediate implant stability of 22.2N-cm (95% CI 5.3; 39.0), which continued throughout the early postoperative course and persisted through the nine- (155N-cm 95% CI 113; 197) and 12-month (171N-cm 95% CI 134.2; 209.4) time points. This is in comparison with the blood clot of 1.4N-cm (95% CI 0.7; 2.1), 128.6N-cm (95% CI 66.8; 190.4), and 140.7N-cm (95% CI 78.8; 202.5) and particulate xenograft, 1.3N-cm (95% CI 0.6; 2.0), 132.1N-cm (95% CI 94.5; 169.7), and 101.5 (95% CI 59.5; 143.5), respectiv allows osseointegration without loss of stability through 12 months of follow-up. This novel adhesive has the potential to stabilize implants placed in sites with inadequate bony support.Anomalous right ventricle muscle bands and apical ventricular septal defect are two anomalies sometimes associated. We report a fetal diagnosis of a large apical ventricular septal defect, right intraventricular obstruction caused by anomalous muscle bands; consequently, the high right intraventricular pressure resulted in a right-to-left bulging of ventricular septum and moderate tricuspid regurgitation. Postnatal echocardiogram confirmed the fetal diagnosis and defined accurately the right ventricular anatomy through the three-dimensional echocardiographic assessment.
To study the influences of posterior tibial nerve stimulation (PTNS) on neurogenic bladder and the expression of transient receptor potential (TRP) channels and P2X receptors in rats with spinal cord injury (SCI) and explore the possible mechanism.
SCI model was established by modified Allen's method and PTNS was performed. Urodynamic indexes and Haematoxylin and Eosine staining of bladder tissue were used to evaluate the therapeutic effect. The expression of TRP channels and P2X receptors in the bladder and dorsal root ganglia (DRG) was detected by real-time PCR and Western blot.
The low compliance of bladder in treatment group was significantly improved compared with SCI group, and the infiltration of inflammatory cells in bladder tissue was significantly reduced. At the same time, the expression of TRP and P2X in bladder and DRG was partially restored after the treatment of PTNS.
PTNS is an effective therapy for SCI-induced neurogenic bladder via the TRP/P2X signaling pathway.

However, uncontrolled transportation and synergistic responses remain challenges. Here, a self-assembled selenopeptide nanoparticle that strengthens tumor chemoimmunotherapy through the activation of natural killer (NK) cells by the oxidative metabolite of the selenopeptide is developed. With the advantages of the enzyme-induced size-reduction and the reactive-oxygen-species-driven deselenization, this selenopeptide is able to deliver therapeutics, e.g., doxorubicin (DOX), to solid tumors and further activate the NK cells in a programmed manner. Importantly, in vitro and in vivo results prove the mutual promotion between the DOX-induced chemotherapy and the selenopeptide-induced immunotherapy, which synergistically contribute to the improved antitumor efficacy. It is anticipated that the selenopeptide may provide a type of promising stimuli-responsive immune modulator for versatile biomedical applications.
