Disclosure of suicidal thoughts and behaviors: The impact of suicide event type

alexandrossfakianakis shared this article with you from Inoreader Disclosure of suicidal thoughts and behaviors: The impact of suicide event type Via Journal of Clinical Psychology Abstract Objectives Despite its importance, limited work has investigated the nuances of suicidal thoughts and behavior self-disclosure. The present study aimed to examine potential differences in self-disclosure based on whether an individual has disclosed suicidal thinking versus behavior. Methods Two hundred and four participants having disclosed their suicidal thoughts or behaviors completed a battery of online questionnaires assessing several key aspects of disclosure (i.e., disclosure recipient, perceived helpfulness of disclosure, impact on treatment seeking), as it pertained to both one's first and overall disclosure experiences. Results Individuals who disclosed a suicide attempt, versus ideation, were more likely to have disclosed to a formal support (i.e., health professional) and to seek professional help following disclosure. No significant group differences in perceived helpfulness of experiences were found. Conclusion It may be beneficial to increase opportunities for disclosure of suicidal thinking. Overall, disclosures were perceived as helpful and may not impede future help-seeking behavior. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

The response of dual‐species bacterial biofilm to 2% and 5% NaOCl mixed with etidronic acid: a laboratory real‐time evaluation using optical coherence tomography.

alexandrossfakianakis shared this article with you from Inoreader The response of dual‐species bacterial biofilm to 2% and 5% NaOCl mixed with etidronic acid: a laboratory real‐time evaluation using optical coherence tomography. Via International Endodontic Journal Abstract Aim The addition of etidronic acid (HEDP) to sodium hypochlorite (NaOCl) could increase the antibiofilm potency of the irrigant, while maintaining the benefits of continuous chelation. Studies conducted so far have shown that mixing HEDP with NaOCl solutions of relatively low concentration does not compromise the antibiofilm efficacy of the irrigant. However, the working lifespan of NaOCl may decrease resulting in a reduction of its antibiofilm efficacy over time (efficiency). In this regard, continuous irrigant replenishment needs to be examined. This study investigated the response of a dual-species biofilm when challenged with 2% and 5% NaOCl mixed with HEDP for a prolonged timespan and under steady laminar flow. Methodology Dual-species biofilms comprised of Streptococcus oralis J22 and Actinomyces naeslundii T14V-J1 were grown on human dentine discs in a constant depth film fermenter (CDFF) for 96 h. Biofilms were treated with 2% and 5% NaOCl, alone or mixed with HEDP. Irrigants were applied under steady laminar flow for 8 min. Biofilm response was evaluated by means of optical coherence tomography (OCT). Biofilm removal, biofilm disruption, rate of biofilm loss and disruption as well as bubble formation were assessed. One-way ANOVA, Wilcoxon's signed-rank test and Kruskal-Wallis H test were performed for statistical analysis of the data. The level of significance was set at a ≤ 0.05. Results Increasing NaOCl concentration resulted in increased biofilm removal and disruption, higher rate of biofilm loss and disruption and increased bubble formation. Mixing HEDP with NaOCl caused a delay in the antibiofilm action of the latter, without compromising its antibiofilm efficacy. Conclusions NaOCl concentration dictates the biofilm response irrespective of the presence of HEDP. The addition of HEDP resulted in a delay in the antibiofilm action of NaOCl. This delay affects the efficiency, but not the efficacy of the irrigant over time. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

Edaravone dexborneol protects cerebral ischemia reperfusion injury through activating Nrf2/HO‐1 signaling pathway in mice

alexandrossfakianakis shared this article with you from Inoreader Edaravone dexborneol protects cerebral ischemia reperfusion injury through activating Nrf2/HO‐1 signaling pathway in mice Via Fundamental & Clinical Pharmacology Abstract Stroke is the leading cause of disability and death. When blood flow is restored after prolonged ischemia and hypoxia, it leads to excessive production of reactive oxygen species (ROS), increased local inflammation and apoptosis, which are the cause of most cerebral ischemia reperfusion injury (CIRI), leading to secondary brain tissue damage. Edaravone dexborneol is a novel neuroprotective agent consisting of edaravone and borneol. Studies have shown that it has synergistic antioxidant and anti-inflammatory effects. However, whether Edaravone dexborneol stimulates the Nrf2/HO-1 pathway to regulate NADPH oxidase 2 (NOX2) remains unclear. In this study, wild type (WT) mice and Nrf2 knockout (KO) mice were used to investigate the antioxidant, anti-inflammatory and anti-apoptotic effects of Edaravone dexborneol on CIRI and its mechanism. The cognitive function of mice was evaluated with the Morris Water Maze (MWM) test and the cell structures of hippocampus were observed by HE stainin g. Nrf2, HO-1 and NOX2 proteins and apoptosis-related proteins Bcl-2, Bax and Caspase 3 were detected by Western blotting. Nrf2, HO-1, NOX2 and inflammatory factors TNF-α, IL-1β, IL-4 and IL-10 were detected by real time polymerase chain reaction. The results showed that Edaravone dexborneol treatment improved learning and memory performance, neuronal damage, and enhanced antioxidant, inflammation, and apoptosis in CIRI mice. In addition, Edaravone dexborneol induced the activation Nrf2/HO-1 signaling pathway activation while inhibiting NOX2 expression. Overall, these results indicate that Edaravone dexborneol ameliorates CIRI-induced memory impairments by activating Nrf2/HO-1 signaling pathway and inhibiting NOX2. View on the web Inoreader.

Immunosuppressants contribute to a reduced risk of Parkinson’s disease in rheumatoid arthritis

alexandrossfakianakis shared this article with you from Inoreader Immunosuppressants contribute to a reduced risk of Parkinson's disease in rheumatoid arthritis Via International Journal of Epidemiology - Advance Access Abstract Background Observational studies have suggested a decreased risk of Parkinson's disease (PD) in patients with rheumatoid arthritis (RA). However, the results are controversial and the biological mechanism underlying this effect remains largely unknown. Methods T he effect sizes of five observational studies were summarized to determine the association between RA and PD. A two-step Mendelian randomization (TSMR) analysis was conducted using genome-wide association studies data sets of RA, PD and prescription of non-steroidal anti-inflammatory drugs (NSAIDs), immunosuppressants (IS) and glucocorticoids (GC). A multivariable MR (MVMR) was also performed to verify the impact of prescription history on PD risk. Results Integrated data from observational studies showed that RA was associated with a decreased risk of PD in the European population (effect size = –0.38, P = 0.004). We found that genetically predicted RA was correlated with a decreased risk of PD [odds ratio (OR) = 0.91, P = 0.007]. In the TSMR, RA patients tended to have an increased prescription of GC (OR = 1.16, P = 2.96e − 07) and IS (OR = 1.77, P = 5.58e − 64), which reduced the risk of PD (GC: OR = 0.86, P = 0.0270; IS: OR = 0.82, P = 0.0277), respectively. Further MVMR analysis demonstrated that only IS was linked to a decreased risk of PD (OR = 0.86, P = 0.004). Conclusion This work clarified that patients with RA had a decreased risk of PD, which was partially attributed to the use of IS in RA patients but not GC or NSAIDs. View on the web Inoreader.

Dual-Phase 18F-FP-CIT PET in 2 Different Clinical Phenotypes of Sporadic Creutzfeldt-Jakob Disease

alexandrossfakianakis shared this article with you from Inoreader Dual-Phase 18F-FP-CIT PET in 2 Different Clinical Phenotypes of Sporadic Creutzfeldt-Jakob Disease Via Clinical Nuclear Medicine - Published Ahead-of-Print Early diagnosis of Creutzfeldt-Jakob disease (CJD) patients is often challenging due to the low sensitivity of the current clinical diagnostic criteria. We describe MRI and dual-phase 18F-FP-CIT PET findings in 2 cases of sporadic CJD presenting different clinical phenotypes (Heidenhain variant and corticobasal syndrome). Our case series suggest that dual-phase FP-CIT-PET findings may improve the diagnosis of CJD by combining the perfusion patterns in early phase with the dopamine transporter density in delayed phase. Familiarity with these dual-phase FP-CIT PET findings is helpful for early correct diagnosis of CJD. View on the web Inoreader. Take back control of your news feed.

Nivolumab Immunotherapy–Related Skin Reactions Detected on 18F-FDG PET/CT in Renal Cell Cancer

alexandrossfakianakis shared this article with you from Inoreader Nivolumab Immunotherapy–Related Skin Reactions Detected on 18F-FDG PET/CT in Renal Cell Cancer Via Clinical Nuclear Medicine - Published Ahead-of-Print Nivolumab, a fully human immunoglobulin G4 anti–programmed cell death 1 antibody, provides a novel therapy option for patients with metastatic cancers. Immunotherapy agents have been associated with immune-related adverse events (irAEs), which may be detected on 18F-FDG PET/CT. Cutaneous toxicities are one of the most common irAEs in the form of maculopapular rash (eczema-like spongiotic dermatitis) and pruritus. These irAEs may lead to false-positive findings on PET/CT done during the treatment. One should be aware of the potential irAEs while interpreting PET/CT to avoid misinterpretation.

The Central Cavitation in Pulmonary Diffuse Large B-Cell Lymphoma Detected by 18F-FDG PET/CT

alexandrossfakianakis shared this article with you from Inoreader The Central Cavitation in Pulmonary Diffuse Large B-Cell Lymphoma Detected by 18F-FDG PET/CT Via Clinical Nuclear Medicine - Published Ahead-of-Print Primary pulmonary diffuse large B-cell lymphoma is a rare type of extranodal lymphoma with PET/CT manifestations of consolidations, ground-glass opacities, and high 18F-FDG uptake. Because of its rarity and the lack of typical imaging features, it can hardly be diagnosed through PET/CT. The central cavitation was occasionally seen in pulmonary diffuse large B-cell lymphoma and may be a key imaging feature in differential diagnoses. In this report, we describe an 80-year-old man diagnosed as having pulmonary diffuse large B-cell lymphoma, which demonstrated the central cavitation detected by 18F-FDG PET/CT.

Developing a Multimodal Monitoring System for Geriatric Depression: A Feasibility Study

alexandrossfakianakis shared this article with you from Inoreader Developing a Multimodal Monitoring System for Geriatric Depression: A Feasibility Study Via Computers Informatics Nursing - Published Ahead-of-Print The Internet of Medical Things is promising for monitoring depression symptoms. Therefore, it is necessary to develop multimodal monitoring systems tailored for elderly individuals with high feasibility and usability for further research and practice. This study comprised two phases: (1) methodological development of the system; and (2) system validation to evaluate its feasibility. We developed a system that includes a smartphone for facial and verbal expressions, a smartwatch for activity and heart rate monitoring, and an ecological momentary assessment application. A sample of 21 older Koreans aged 65 years and more was r ecruited from a community center. The 4-week data were collected for each participant (n = 19) using self-report questionnaires, wearable devices, and interviews and were analyzed using mixed methods. The depressive group (n = 6) indicated lower user acceptance relative to the nondepressive group (n = 13). Both groups experienced positive emotions, had regular life patterns, increased their self-interest, and stated that a system could disturb their daily activities. However, they were interested in learning new technologies and actively monitored their mental health status. Our multimodal monitoring system shows potential as a feasible and useful measure for acquiring mental health information about geriatric depression. View on the web Inoreader.

MEOX2 homeobox gene promotes growth of malignant gliomas

alexandrossfakianakis shared this article with you from Inoreader MEOX2 homeobox gene promotes growth of malignant gliomas Via Neuro-Oncology Advance Access Abstract Background Glioblastoma (GBM) is an aggressive tumor that frequently exhibits gain of chromosome 7, loss of chromosome 10 and aberrantly activated receptor tyrosine kinase signaling pathways. Previously, we identified Mesenchyme Homeobox 2 (MEOX2), a gene located on chromosome 7, as an upregulated transcription factor in GBM. Overexpressed transcription factors can be involved in driving GBM. Here, we aimed to address the role of MEOX2 in GBM. Methods Patient-derived GBM tumorspheres were used to constitutively knockdown or overexpress MEOX2 and subjected to in vitro assays including western blot to assess ERK phosphorylation. Cerebral organoid models were used to investigate the role of MEOX2 in growth initiation. Intracranial mouse implantation models were used to assess the tumorigenic potential of MEOX2. RNA-sequencing, ACT-seq and CUT&Tag w ere used to identify MEOX2 target genes. Results MEOX2 enhanced ERK signaling through a feed-forward mechanism. We identified Ser 155 as a putative ERK-dependent phosphorylation site upstream of the homeobox-domain of MEOX2. S155A substitution had a major effect on MEOX2 protein levels and altered its subnuclear localization. MEOX2 overexpression cooperated with p53 and PTEN loss in cerebral organoid models of human malignant gliomas to induce cell proliferation. Using high-throughput genomics, we identified putative transcriptional target genes of MEOX2 in patient-derived GBM tumorsphere models and a fresh frozen GBM tumor. Conclusions We identified MEOX2 as an oncogenic transcription regulator in GBM. MEOX2 increases proliferation in cerebral organoid models of GBM and feeds into ERK signaling that represents a core signaling pathway in GBM. View on the web Inoreader.

Optimization of vonoprazan‐amoxicillin dual therapy for eradicating Helicobacter pyloriinfection in China: A prospective, randomized clinical pilot study

alexandrossfakianakis shared this article with you from Inoreader Optimization of vonoprazan‐amoxicillin dual therapy for eradicating Helicobacter pyloriinfection in China: A prospective, randomized clinical pilot study Via Helicobacter Abstract Background Vonoprazan-amoxicillin (VA) dual therapy has been shown to achieve acceptable cure rates for treatment of Helicobacter pylori(H. pylori) in Japan. Its effectiveness in other regions is unknown. We aimed to explore the efficacy of VA dual therapy as first-line treatment for H. pyloriinfection in China. Methods This was a single center, prospective, randomized clinical pilot study conducted in China. Treatment naive H. pyloriinfected patients were randomized to receive either low- or high-dose amoxicillin-vonoprazan consisting of amoxicillin 1 g either b.i.d. or t.i.d plus VPZ 20 mg b.i.d for 7 or 10 days. 13C-urea breath tests were used to access the cure rate at least 4 weeks after treatment. Results Three hundred and twenty-three patients were assessed, and 119 subjects were randomized. The eradication rates of b.i.d. amoxicillin for 7 and 10 days, t.i.d. amoxicillin for 7 and 10 days were 66.7% (16/24), 89.2% (33/37), 81.0% (17/21), and 81.1% (30/37) (p = .191) by intention-to-treat analysis, respectively, and 72.7% (16/22), 89.2% (33/37), 81.0% (17/21), and 81.1% (30/37) (p = .454) by per-protocol analysis, respectively. Conclusion Neither 7- or 10-day VA dual therapy with b.i.d. or t.i.d. amoxicillin provides satisfied efficacy as the first-line treatment for H. pyloriinfection in China. Further optimization is needed. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.
