Eye movements as predictor of cognitive improvement after cognitive remediation therapy in patients with schizophrenia.

Aim: Baseline cognitive functions of patients predicted the efficacy of cognitive remediation therapy (CRT), but results are mixed. Eye movement is a more objective and advanced assessment of cognitive functions than neuropsychological testing. We aimed to investigate the applicability of eye movements in predicting cognitive improvement after patients with schizophrenia were treated with CRT. Methods: We recruited 79 patients with schizophrenia to complete 8 weeks of CRT and assessed their cognitive improvement outcomes. Eye movements were assessed by prosaccades, antisaccades, and free-viewing tasks at baseline, and neuropsychological tests in four cognitive domains were assessed before and after treatment to calculate treatment outcomes. Predictors of demographic information, clinical characteristics, and eye movement measures at baseline on cognitive improvement outcomes were analyzed using logistic regression analysis. We further compared the predictive performance between eye movement measurements and neuropsychological test regarding the effect of CRT on cognitive improvement, and explored factors that could be affect the treatment outcomes in different cognitive domains. Results: As operationally defined, 33 patients showed improved in cognition (improved group) and 46 patients did not (non-improved group) after CRT. Patients with schizophrenia being employed, lower directional error rate in antisaccade task, and lower the gap effect (i.e., the difference in saccadic latency between the gap condition and overlap condition) in prosaccade task at baseline predicted cognitive improvement in CRT. However, performance in the free-viewing task not associated with cognitive improvement in patients in CRT. Our results show that eye-movement prediction model predicted the effect of CRT on cognitive improvement in patients with schizophrenia better than neuropsychological prediction model in CRT. In addition, baseline eye-movements, cognitive reserve, antipsychotic medication dose, anticholinergic cognitive burden change, and number of training sessions were associated with improvements in four cognitive domains. Conclusion: Eye movements as a non-invasiveness, objective, and sensitive method of evaluating cognitive function, and combined saccadic measurements in pro- and anti-saccades tasks could be more beneficial than free-viewing task in predicting the effect of CRT on cognitive improvement in patients with schizophrenia.

The Clinical Manifestation, Executive Dysfunction, and Caregiver Strain in Subthreshold Attention-Deficit/Hyperactivity Disorder.

OBJECTIVE: Subthreshold attention-deficit/hyperactivity disorder (ADHD) has been suggested to be a "morbid condition" which also needs medical attention. METHODS: The present study recruited 89 children with subthreshold ADHD (sADHD), 115 children with diagnosed ADHD (cADHD), and 79 healthy controls (HC) to explore the clinical manifestation, executive functions (EFs) of sADHD, and the caregiver strain. The clinical manifestation was evaluated through clinical interviews and parent-reports. Executive functions were assessed both experimentally and ecologically. Caregiver strain was measured by a parent-reported questionnaire. RESULTS: For the clinical manifestation, both sADHD and cADHD indicated impairments when compared with HC. The comorbidities and the scaled symptoms indicated that the externalizing behaviors were relatively less serious in sADHD than cADHD, whereas the internalizing behaviors between two groups were comparable. For ecological EFs, sADHD scored between cADHD and HC in inhibition and working memory. For experimental EFs, sADHD was comparable to cADHD in inhibition, shifting, and was worse than cADHD in verbal working memory. For the caregiver strain, all scores of sADHD were between that in cADHD and that in HC. CONCLUSION: Our present findings supported the suggestion of subthreshold ADHD as "morbid condition," which should be treated with caution in clinical practice, especially for the internalizing behaviors and some key components of EFs.

Analysis of Risk Factors Related to the Efficacy of Foramen Ovale Closure as a Therapy for Migraine.

This study aimed to monitor the incidence of migraine non-remission after percutaneous patent foramen ovale (PFO) closure and to discuss relevant risk factors. Recently, evidence of a relationship between the presence of PFO and migraines has been found, and PFO closure has been pointed out as a possible treatment for migraineurs.A retrospective analysis was conducted, which involved 139 patients diagnosed with PFO and associated migraine who underwent percutaneous PFO closure in The First Affiliated Hospital of Zhengzhou University from October 2019 to April 2021. All the considered patients were evaluated using the Headache Impact Test (HIT-6™) and classified with a score higher than 55 points before closure. The HIT-6™ score was re-evaluated 1-6 months after the intervention. HIT-6™ ≤ 55 was defined as headache remission (n = 93) and > 55 as headache non-remission (n = 46). A logistic regression model was developed to identify the risk factors of headache non-remission after PFO closure.The incidence of headache non-remission after PFO closure was 33.09%. Statistically significant differences were observed between the two groups as regards age and serum phosphorus level (P < 0.05). History of smoking, atrial fibrillation, absolute lymphocyte count, platelet-to-lymphocyte ratio, and interventricular septal thickness were identified as independent risk factors for headache non-remission following PFO closure, which were statistically significant (P < 0.05).

Hsa_circ_0004831 downregulation is partially responsible for atorvastatinalleviated human umbilical vein endothelial cell injuries induced by ox-LDL through targeting the miR-182-5p/CXCL12 axis.

BACKGROUND: The dysfunction and injury of human umbilical vein endothelial cells (HUVECs) are key events of atherosclerosis (AS). Atorvastatin (ATV) has been shown to play a protective role on endothelial cells. However, the associated molecular mechanisms remain not fully illustrated. METHODS: HUVECs were treated with oxidized low-density lipoprotein (ox-LDL) to mimic the pathological conditions of endothelial cell injury in AS. Cell injuries were assessed according to cell viability, cell apoptosis, cycle progression, oxidative stress and inflammatory responses using CCK-8 assay, flow cytometry assay or commercial kits. The expression of hsa_circ_0004831, miR-182-5p, and C-X-C motif chemokine 12 (CXCL12) mRNA was examined using quantitative real-time PCR (qPCR). The expression of CXCL12 protein was quantitated by western blot. The predicted target relationship between miR-182-5p and hsa_circ_0004831 or CXCL12 was verified by pull-down assay, dual-luciferase reporter assay or RIP assay. RESULTS: The expression of hsa_circ_0004831 was upregulated by ox-LDL but downregulated by ATV in HUVECs. ATV promoted cell viability and cell cycle progression but inhibited apoptosis, oxidative stress and inflammation in ox-LDL-treated HUVECs, while the role of ATV was partially reversed by hsa_circ_0004831 overexpression. MiR-182-5p was targeted by hsa_circ_0004831, and hsa_circ_0004831 overexpression-restored apoptosis, oxidative stress and inflammation were blocked by miR-182-5p restoration. Further, CXCL12 was targeted by miR-182-5p, and miR-182-5p inhibition-stimulated apoptosis, oxidative stress and inflammation were lessened by CXCL12 knockdown. CONCLUSION: Hsa_circ_0004831-targeted miR-182-5p/CXCL12 regulatory network is one of the pathways by which ATV protects against ox-LDL-induced endothelial injuries.

Clinical observation of neoadjuvant chemotherapy with pyrotinib plus trastuzumab in HER2-positive breast cancer: a cohort study.

BACKGROUND: Pyrotinib is a new small-molecule tyrosine kinase inhibitor (TKI). However, the efficacy of pyrotinib in neoadjuvant therapy for HER2-positive breast cancer is unknown. This paper is a population-based cohort study, and the purpose is to evaluate the efficacy and safety of pyrotinib plus trastuzumab in a neoadjuvant setting for HER2-positive early or locally advanced breast cancers, and to compare it with that of pertuzumab plus trastuzumab. METHODS: This cohort study included 166 patients with HER2-positive breast cancer who received neoadjuvant therapy and underwent surgery. Case groups: Group I: 63 patients received pyrotinib + trastuzumab; Group II: 50 patients received pertuzumab + trastuzumab. The control group consisted of 53 patients treated with trastuzumab alone in combination with neoadjuvant chemotherapy. Univariate logistic regression analysis was applied. Enumeration data were processed by Fisher's exact test. RESULTS: The total pathological complete response (tpCR) rate of Group I was 63.49% (40/63); the breast pathological complete response (bpCR) rate was 76.19% (48/63); and the objective response rate (ORR) was 100% (63/63). Compared with the tpCR rate of 54.00% (27/50), bpCR rate of 58.00% (29/50), and ORR 100% (50/50) of Group II, there was no statistical difference. Regarding adverse events (AEs), diarrhea (n=56, 88.89%) was the most frequent in the group I, including 7 participants who developed grade 3 diarrhea (11.11%), followed by leukopenia (n=48, 76.19%). In the meantime, there was only 1 patient experienced grade IV thrombocytopenia. Hormone receptor (HR)-negative patients were more likely to reach tpCR as compared to HR-positive patients (61.54% vs. 37.50%, P=0.002, 95% CI: 1.423 to 4.997), and the tpCR rate of tumor, node, metastasis (TNM) stage III 37.04% (20/54) was significantly lower than that of stage II 54.46% (61/112), which was statistically significant (P=0.048, 95% CI: 1.064 to 4.041). No recurrence or metastasis was found during short-term follow-up. CONCLUSIONS: Pyrotinib plus trastuzumab combined with neoadjuvant chemotherapy showed good short-term efficacy in HER2-positive breast cancer, and the AEs developed were all manageable. More sample data is required to further support the comparison with pertuzumab plus trastuzumab.

Developing Cancer Informatics Applications and Tools Using the NCI Genomic Data Commons API.

The NCI Genomic Data Commons (GDC) was launched in 2016 and makes available over 4 petabytes (PB) of cancer genomic and associated clinical data to the research community. This dataset continues to grow and currently includes over 14,500 patients. The GDC is an example of a biomedical data commons, which collocates biomedical data with storage and computing infrastructure and commonly used web services, software applications, and tools to create a secure, interoperable, and extensible resource for researchers. The GDC is (i) a data repository for downloading data that have been submitted to it, and also a system that (ii) applies a common set of bioinformatics pipelines to submitted data; (iii) reanalyzes existing data when new pipelines are developed; and (iv) allows users to build their own applications and systems that interoperate with the GDC using the GDC Application Programming Interface (API). We describe the GDC API and how it has been used both by the GDC itself and by third parties. Cancer Res; 77(21); e15-18. ©2017 AACR.
