For patients with symptomatic unilateral internal carotid artery (ICA) occlusion, impaired cerebrovascular reactivity (CVR) indicates increased stroke risk. Here, the role of collateral activation remains a matter of debate, whereas angio-anatomical collateral abundancy does not necessarily imply sufficient compensatory flow provided. We aimed to further elucidate the role of collateral activation in the presence of impaired CVR. From a prospective database, 62 patients with symptomatic unilateral ICA occlusion underwent blood oxygenation-level dependent (BOLD) fMRI CVR imaging and a transcranial Doppler (TCD) investigation for primary and secondary collateral activation. Descriptive statistic and multivariate analysis were used to evaluate the relationship between BOLD-CVR values and collateral activation. Patients with activated secondary collaterals exhibited more impaired BOLD-CVR values of the ipsilateral hemisphere (p = 0.02). Specifically, activation of leptomeningeal collaterals showed severely impaired ipsilateral hemisphere BOLD-CVR values when compared to activation of ophthalmic collaterals (0.05 ± 0.09 vs. 0.12 ± 0.04, p = 0.005). Moreover, the prediction analysis showed leptomeningeal collateral activation as a strong independent predictor for ipsilateral hemispheric BOLD-CVR. In our study, ipsilateral leptomeningeal collateral activation is the sole collateral pathway associated with severely impaired BOLD-CVR in patients with symptomatic unilateral ICA occlusion.
HD patients using dialysis catheters have been associated with chronic inflammatory state. In Egypt 6.6% of HD patients use catheters, of which short term catheters represent 59.6% and 40.4% with long-term catheters. In this study, we
to assess the effect of Taurolidine citrate and unfractionated heparin combination (Taurolock-hep500™) as a lock solution compared to unfractionated heparin alone on inflammatory markers, incidence of catheter related blood stream infections (CRBSI) and dialysis adequacy in HD patients with temporary HD catheters only, for 4 weeks duration.
Sixty ESRD patients from hemodialysis units in Ain-Shams University hospitals (ASUH) at the time of catheter insertion we enrolled in our study. They were randomized into two groups
Thirty patients received Taurolock-hep500™ as a catheter lock solution at the end of each hemodialysis session.
Thirty patients received unfractionated heparin as a catheter lock solution. hsCRP and IL-6 were measured at baseline and 1 month after using the lock solutions. Blood cultures were done in patients who developed symptoms of catheter related infections.
At the end of the study, Inflammatory markers were significantly higher in group 2 (
-value 0.045, 0.001, and 0.018 for WBCs, hsCRP and IL-6, respectively). this website Group 1 had better dialysis adequacy assessed by URR (
-value 0.007 and 0.001, respectively). CRBSI were demonstrated in nine patients in group 2 (30%) in contrast to one patient only in group 1(3.3%) (
-value 0.006) with pseudomonas being the most common isolated organism (27.7%).
Use of (Taurolock-hep500™) for temporary hemodialysis catheters was associated with lower levels of inflammation markers and lower incidence of CRBSI and better catheter performance.
Use of (Taurolock-hep500™) for temporary hemodialysis catheters was associated with lower levels of inflammation markers and lower incidence of CRBSI and better catheter performance.University-based sexual violence prevalence is worryingly high and leads to many serious consequences for health and academic achievement. Although previous work has documented greater risk for sexual violence among Indigenous Peoples, little is known about university-based sexual violence experienced by Indigenous students. Using a large-scale study of university-based sexual violence in Canada, the current study aims to (1) examine the risk of sexual violence against Indigenous students compared to non-Indigenous students, and (2) to document sexual violence experiences of Indigenous students. Undergraduate students from six universities (N = 5,627) completed online questionnaires regarding their experience and consequences of university-based sexual violence (e.g., forms of sexual violence experiences, gender, and status of the perpetrator, context of the violence, PTSD, disclosure). Findings indicated that compared with their non-Indigenous peers, Indigenous students experienced significantly higher levels of sexual harassment. However, no difference was found for unwanted sexual behaviors, nor for sexual violence contexts. Among Indigenous students, those having experienced sexual violence after age 18 (outside university) were more likely to report university-based sexual violence. Overall, findings highlight that Indigenous students, as well as non-Indigenous students, experience university-based sexual violence. Given their history, Indigenous students may have different needs, so sustainable policies that foster cultural safety on all campuses are clearly needed.New treatments are required for advanced prostate cancer; however, there are fewer preclinical models of prostate cancer than other common tumor types to test candidate therapeutics. One opportunity to increase the scope of preclinical studies is to grow tissue from patient-derived xenografts (PDXs) as organoid cultures. Here we report a scalable pipeline for automated seeding, treatment and an analysis of the drug responses of prostate cancer organoids. We established organoid cultures from 5 PDXs with diverse phenotypes of prostate cancer, including castrate-sensitive and castrate-resistant disease, as well as adenocarcinoma and neuroendocrine pathology. We robotically embedded organoids in Matrigel in 384-well plates and monitored growth via brightfield microscopy before treatment with poly ADP-ribose polymerase inhibitors or a compound library. Independent readouts including metabolic activity and live-cell imaging-based features provided robust measures of organoid growth and complementary ways of assessing drug efficacy. Single organoid analyses enabled in-depth assessment of morphological differences between patients and within organoid populations and revealed that larger organoids had more striking changes in morphology and composition after drug treatment. By increasing the scale and scope of organoid experiments, this automated assay complements other patient-derived models and will expedite preclinical testing of new treatments for prostate cancer.
