This study was designed for evaluation of CEUS (contrast-enhanced ultrasound) for the detection of endoleaks after EVAR (endovascular aortic aneurysms repair) as an alternative to CTA (computed tomography angiography), the gold standard in post-EVAR surveillance.
Post-EVAR surveillance of patients who underwent CEUS and CTA was retrospectively analyzed to compare the accuracy of CEUS compared to CTA. For that, the following parameters were analyzed the largest aneurysm diameter, type of endoleaks, and the time elapsed after EVAR using both surveillance tests.
The study involved 110 pairs of exams in patients with infrarenal aortoiliac or isolated iliac artery aneurysm, covering predominantly a male population (89%). The time elapsed after EVAR using CEUS or CTA exams were statistically similar, ranging from one to 58months (mean 12.2) and one to 65months (mean 9.7), respectively (
= 0.124). CEUS sensitivity was 75.5%, specificity 96.7%, false positives were 24.5%, and false negatives were 3.3%. The ac efficacy and, particularly, safety, and must be considered in EVAR surveillance protocols so that its use becomes widespread. We understand that CEUS, as a surveillance exam, considerably reduces risks to patients compared to CTA.
Contrast-enhanced ultrasound was more effective than CTA in identifying and characterizing endoleaks in patients undergoing EVAR, especially type II endoleaks. The advantages include efficacy and, particularly, safety, and must be considered in EVAR surveillance protocols so that its use becomes widespread. We understand that CEUS, as a surveillance exam, considerably reduces risks to patients compared to CTA.Intimate partner violence (IPV) is prevalent among young sexual and gender minorities assigned male at birth (YSGM-AMAB). However, few studies have examined the chronicity or distinguished between minor and severe forms of IPV among YSGM-AMAB. Furthermore, while past research has documented differences in IPV by race/ethnicity, sexual identity, gender identity, income, and education in other populations, few studies have examined these sociodemographic characteristics in relation to IPV in YSGM-AMAB. Thus, the present study aims to (1) estimate past year prevalence and chronicity of minor and severe forms of IPV victimization and perpetration in a diverse sample of (N = 665) YSGM-AMAB in New York City, and (2) examine differences in IPV prevalence and chronicity by the aforementioned sociodemographic characteristics. Cross-sectional data from informed these descriptive and inferential analyses. Nearly half of all participants reported past year IPV victimization and approximately 40% reported perpetpromote more favorable sociopolitical conditions for YSGM-AMAB.
Tardive dyskinesia, psychotic relapse and treatment-refractory psychosis have long been associated. A common underlying mechanism involving antipsychotic-induced ‘supersensitivity’, albeit in different brain pathways, was proposed as early as 1978. This piece seeks to reappraise the concept and potential implications of antipsychotic-induced supersensitivity.
Evidence increasingly suggests that chronic antipsychotic exposure induces neuroadaptive physiological changes in dopaminergic, and other, neurotransmitter systems that may render some individuals more vulnerable to psychotic relapse – including those receiving continuous antipsychotic treatment. It is possible that in treating every episode of psychosis with prolonged or indefinite antipsychotic therapy, we paradoxically increase the risk of psychotic relapse in a significant proportion of people. A greater appreciation of supersensitivity may allow us to optimise any potential benefits of antipsychotics while minimising the risk of inadvertent iatring the risk of inadvertent iatrogenic harms. More research is needed to improve our understanding of the underlying neurophysiology of supersensitivity and to better identify which individuals are most vulnerable to its development. It is time we paid more attention to the concept, emerging evidence and potential implications of antipsychotic-induced supersensitivity and, where appropriate, adjusted our practice accordingly.Chimeric antigen receptor T cells (CAR-Ts) constitute a novel therapeutic strategy for relapsed/refractory B-cell malignancies. JNK signaling pathway inhibitors With the extensive application of CAR-T therapy in clinical settings, CAR-T-associated toxicities have become increasingly apparent. However, information regarding the associated infections is limited. We aimed to evaluate the incidence of infection during CAR-T therapy and identify the potential risk factors. Especially, we evaluated infections and the associated risk factors in 92 patients. The cohort included patients with acute lymphoblastic leukemia (n = 58) and non-Hodgkin lymphoma (n = 34). Fifteen cases of infection (predominantly bacterial) were observed within 28 days of CAR-T therapy, with an infection density of 0.5 infections for every 100 days-at-risk. Neutropenia before CAR-T therapy (P = .005) and prior infection (P = .046) were independent risk factors associated with infection within 28 days after CAR-T therapy; corticosteroid treatment during cytokine release syndrome (P = .013) was an independent risk factor during days 29-180 after CAR-T infusions. Moreover, the 2-year survival duration was significantly shorter in patients with infections than in those without (126 vs 409 days; P = .006). Our results suggested that effective anti-infection therapies may improve prognosis of patients who have a high infection risk. The risk of bacterial infections during the early stages of CAR-T therapy and the subsequent risk of viral infections thereafter should be considered to provide the appropriate treatment and improve patient prognosis.Neuro-inflammation plays a key role in the pathophysiology of brain infarction. Cell therapy offers a novel therapeutic option due to its effect on immunomodulatory effects. Amniotic stem cells, in particular, show promise owing to their low immunogenicity, tumorigenicity, and easy availability from amniotic membranes discarded following birth. We have successfully isolated and expanded human amniotic mesenchymal stem cells (hAMSCs). Herein, we evaluated the therapeutic effect of hAMSCs on neurological deficits after brain infarction as well as their immunomodulatory effects in a mouse model in order to understand their mechanisms of action. One day after permanent occlusion of the middle cerebral artery (MCAO), hAMSCs were intravenously administered. RT-qPCR for TNFα, iNOS, MMP2, and MMP9, immunofluorescence staining for iNOS and CD11b/c, and a TUNEL assay were performed 8 days following MCAO. An Evans Blue assay and behavioral tests were performed 2 days and several months following MCAO, respectively. The results suggest that the neurological deficits caused by cerebral infarction are improved in dose-dependent manner by the administration of hAMSCs.
