Patients who take aspirin and sustain traumatic intracranial hemorrhage (tICH) are often transfused platelets in an effort to prevent bleeding progression. The efficacy of platelet transfusion is questionable, however, and some medical societies recommend that platelet reactivity testing (PRT) should guide transfusion decisions. The study hypothesis was that utilization of PRT to guide platelet transfusion for tICH patients suspected of taking aspirin would safely identify patients who did not require platelet transfusion.

This was a retrospective study of patients with blunt tICH who received PRT for known or suspected aspirin use between June 2014 and December 2017 at a level I trauma center. Chart abstraction was conducted to determine home aspirin status, and PRT values were used to classify patients as therapeutic or nontherapeutic on aspirin. Pentylenetetrazol clinical trial Differences were assessed with Kruskal-Wallis and chi-square tests.

157 patients met study inclusion criteria, and 118 (75%) patients had documented prior aspirin use. PRT results were available approximately 1.7h (IQR 0.9, 3.2) after arrival. Upon initial PRT, 70% of patients were considered inhibited and 88% of those patients had aspirin documented as a home medication. Conversely, 18% of patients with home aspirin use had normal platelet reactivity. Clinically significant worsening of the tICH did not significantly differ when comparing those who received platelet transfusion with those who did not (8% versus 7%, P=0.87).

Platelet reactivity testing can detect platelet inhibition related to aspirin and should guide transfusion decisions for head injured patients in the initial hours after trauma.

We focus in particular on the roles of nitric oxide (NO) and prostacyclin (PGI2) in placental endothelium, and propose new hypotheses for the influence and mechanisms of endothelial NO and PGI2 signaling pathways in PE.The success of preclinical drug discovery strongly relies on the ability of experimental models to resemble human pathophysiology. The number of compounds receiving approval for clinical use is limited, and this has led to the development of more physiologically relevant cellular models aimed at making preclinical results more prone to be successfully translated into clinical use. In this review, we summarize the technologies available in the field of high-throughput screening (HTS) using complex cellular models, and describe collaborative initiatives, such as EU-OPENSCREEN, which can efficiently support researchers to easily access state-of-the-art chemical biology platforms for improving the drug discovery process.
Dystonia in cerebral palsy is debilitating but underdiagnosed precluding targeted treatment that is most effective if instituted early. Deep gray matter injury is associated with dystonic cerebral palsy but is difficult to quantify. Objective and clinically feasible identification of injury preceding dystonia could help determine the children at the highest risk for developing dystonia and thus facilitate early dystonia detection.

We examined brain magnetic resonance images from four- to five-day-old neonates after therapeutic hypothermia for hypoxic-ischemic encephalopathy at a tertiary care center. Apparent diffusion coefficient values in the striatum and thalamus were determined using a web-based viewer integrated with the electronic medical record (IBM iConnect Access). The notes of specialists in neonatal neurology, pediatric movement disorders, and pediatric cerebral palsy (physicians most familiar with motor phenotyping after neonatal brain injury) were screened for all subjects through age of fivefor hypoxic ischemic encephalopathy. Objective and clinically feasible neonatal brain imaging assessment could help increase vigilance for dystonia in cerebral palsy.
Onasemnogene abeparvovec was recently approved for the treatment of spinal muscular atrophy (SMA) in children younger than two years; however, clinical trials were primarily completed in children younger than seven months, so practical experience dosing older children began in summer 2019. Here, we look at the safety and efficacy of onasemnogene in seven infants older than sevenmonths who were treated at our center.

Seven patients were included.

Acute viral symptoms with emesis and/or fever were seen in six of seven patients two to threedays after the infusion. Thrombocytopenia occurred in four of seven patients, and six of seven patients had prolonged steroid courses due to persistently elevated liver enzymes, one of whom required escalation to intravenous steroids. link3 All patients demonstrated motor improvements, which were apparent by threemonths, although with continued progress in those patients followed for longer periods of time.

Overall, onasemnogene appears to be efficacious in children older than sevenmonths and well tolerated. Side effects were similar to those previously reported, although more common and in some cases more severe and more prolonged than seen in the original trials. The impact of age, weight, and other confounding factors on development of side effects still needs to be elucidated.

Emergency departments have seen altered patterns of attendance since the beginning of the COVID-19 pandemic, with reductions in the number of attendances for non-COVID-19 - patients. We assessed the use of the emergency department by frequent attenders during the height of the COVID-19 pandemic and explored any changes in emergency department attendance by this group.

As part of ongoing improvement work, we utilised a cohort design to evaluate the difference in patterns of attendance for the frequent attender group in a single centre. We created a 2019 'top attender' cohort and a similar cohort for 2020. We compared admission patterns between the two time periods in order to understand the impact of the COVID-19 pandemic on this group.

Both groups were predominately male. Mental health and substance misuse use problems were common across both cohorts. The majority of patients lived in a socio-economically deprived areas. The median number emergency department visits in 2019, for the top attender cohort was 6 (IQR 4-9) vs 4 (IQR 2-7) for the top attender cohort of 2020 (p<.0013).

This single centre evaluation has shown a significant reduction in emergency department attendances for a frequent attender cohort in a single centre. Future work should investigate the longer-term impact which the COVID-19 pandemic has had on this patient group.

The use of other T cell-based immunotherapies relying on antigen-specific T cells, genetically modified or not, is expanding in various neoplastic diseases. T cell manufacturing has evolved through sophisticated processes to produce T cells with improved therapeutic potential. Clinical-grade manufacturing processes associated with these therapies must meet pharmaceutical requirements and therefore be standardized. Here, we focus on the use of cytokines to expand minimally differentiated T cells, as well as their standardization and harmonization in research and clinical settings.
There is limited evidence of the impact of cannabis legalization on the prevalence of cannabis use and use of other substances. The aim of this exploratory observational study was to compare rates of cannabis use, cigarette smoking, alcohol consumption, and the use of any street drugs during the preconception period and in pregnancy in two convenience samples of pregnant persons in British Columbia, Canada, before and after the legalization of cannabis.

Any pregnant person residing in British Columbia, aged >19 years, at any gestational age was eligible to participate. Pre- and post-legalization study participants were recruited between May and October 2018 and July 2019 and May 2020, respectively. Multivariate models were constructed to examine the effect of legalization on cigarette smoking and the use of cannabis, alcohol, and street drugs, adjusting for demographic, pre-pregnancy, and pregnancy confounders.

From pre- to post-legalization, the prevalence of self-reported cannabis use during the prinatal outcomes, as well as public health interventions and educational programs related to cannabis use, should include the preconception period as an area of focus.
The preliminary evidence presented in this study shows that the legalization of cannabis was associated with 71% higher odds of cannabis use during the preconception period. Studies examining the effects of cannabis use on perinatal outcomes, as well as public health interventions and educational programs related to cannabis use, should include the preconception period as an area of focus.The study of attentional processing in vision has a long and deep history. Recently, several papers have presented insightful perspectives into how the coordination of multiple attentional functions in the brain might occur. These begin with experimental observations and the authors propose structures, processes, and computations that might explain those observations. Here, we consider a perspective that past works have not, as a complementary approach to the experimentally-grounded ones. We approach the same problem as past authors but from the other end of the computational spectrum, from the problem nature, as Marr's Computational Level would prescribe. What problem must the brain solve when orchestrating attentional processes in order to successfully complete one of the myriad possible visuospatial tasks at which we as humans excel? The hope, of course, is for the approaches to eventually meet and thus form a complete theory, but this is likely not soon. We make the first steps towards this by addressing the necessity of attentional control, examining the breadth and computational difficulty of the visuospatial and attentional tasks seen in human behavior, and suggesting a sketch of how attentional control might arise in the brain. The key conclusions of this paper are that an executive controller is necessary for human attentional function in vision, and that there is a 'first principles' computational approach to its understanding that is complementary to the previous approaches that focus on modelling or learning from experimental observations directly.
