DT seems equivalent to BT in treating stroke due to carotid T occlusion in favorable outcome, successful recanalization, 90-day morality and sICH. However, BT may increase the incidence of ICH in this specific type stroke.An 86-year-old lady presented after waking up with left sided paresis and neglect. Right hemispheral stroke was suspected, but initial MRI with Diffusion Weighted Imaging (DWI) was negative and there was no large vessel occlusion. We accordingly withheld intravenous thrombolysis. She did not improve clinically and follow-up MRI after three days showed a marked lesion compatible with acute ischemic stroke in the right middle cerebral artery territory. This case shows that even with a disabling stroke in the anterior circulation initial DWI may be negative. Former studies established that thrombolysis can be safe in these cases when there is no doubt about the clinical diagnosis of acute ischemic stroke.

Intracranial atherosclerotic disease (ICAD) is a common cause of ischemic stroke with a high risk of clinical stroke recurrence. Multiple mechanisms may underlie cerebral ischemia in this condition. The study's objective is to discern the mechanisms of recurrent ischemia in ICAD through imaging biomarkers of impaired antegrade flow, poor distal perfusion, abnormal vasoreactivity, and artery-to-artery embolism.

This prospective multicenter observational study enrolled patients with recent (≤21 days) ischemic stroke or transient ischemic attack (TIA) caused by ICAD with 50-99% stenosis treated medically. We obtained baseline quantitative MRA (QMRA), perfusion MRI (PWI), transcranial Doppler vasoreactivity (VMR), and emboli detection studies (EDS). The primary outcome was ischemic stroke in the territory of the stenotic artery within 1 year of follow-up; secondary outcomes were TIA at 1 year and new infarcts in the territory on MRI at 6-8 weeks.

Amongst 102 of 105 participants with clinical follow-up (mean 253±131 days), the primary outcome occurred in 8.8% (12.7/100 patient-years), while 5.9% (8.5/100 patient-years) had a TIA. A new infarct in the territory of the symptomatic artery was noted in 24.7% at 6-8 weeks. A low flow state on QMRA was noted in 25.5%, poor distal perfusion on PWI in 43.5%, impaired vasoreactivity on VMR in 67.5%, and microemboli on EDS in 39.0%. No significant association was identified between these imaging biomarkers and primary or secondary outcomes.

Despite intensive medical management in ICAD, there is a high risk of clinical cerebrovascular events at 1 year and an even higher risk of new imaging-evident infarcts in the subacute period after index stroke. Hemodynamic and plaque instability biomarkers did not identify a higher risk group. Further work is needed to identify mechanisms of ischemic stroke and infarct recurrence and their consequence on long-term physical and cognitive outcomes.

ClinicalTrials.gov NCT02121028.The current Coronavirus pandemic due to the novel SARS-Cov-2 virus has proven to have systemic and multi-organ involvement with high acuity neurological conditions including acute ischemic strokes. We present a case series of consecutive COVID-19 patients with cerebrovascular disease treated at our institution including 3 cases of cerebral artery dissection including subarachnoid hemorrhage. Knowledge of the varied presentations including dissections will help treating clinicians at the bedside monitor and manage these complications preemptively.

Our study aimed to assess the impacts of neighborhood socioeconomic status on mechanical thrombectomy (MT) outcomes for acute ischemic stroke (AIS).

We conducted a prospective observational study of consecutive adult AIS patients treated with MT at one US comprehensive stroke center from 2012 to 2018. A composite neighborhood socioeconomic score (nSES) was created using patient home address, median household income, percentage of households with interest, dividend, or rental income, median value of housing units, percentage of persons 25 or older with high school degrees, college degrees or holding executive, managerial or professional specialty occupations. Using this score, patients were divided into low, middle and high nSES tertiles. PKM2 inhibitor in vitro Outcomes included 90-day functional independence, in-hospital mortality, length of hospital stay, discharge location, time to recanalization, successful recanalization, and symptomatic intracranial hemorrhage (sICH).

328 patients were included. Between the three nSES gring of the interplay of these factors may lead to timelier evaluation and improvement in patient outcomes.

This study highlights how unadjusted neighborhood socioeconomic status is significantly associated with functional outcome, mortality, and time-to-recanalization following MT for AIS. Since adjustment modifies the significant association, the socioeconomic differences may be influenced by differences in pre-hospital factors that drive severity of stroke and time to recanalization. Better understanding of the interplay of these factors may lead to timelier evaluation and improvement in patient outcomes.With an ageing global community and widening socio-cultural diversity, nurse educators are increasingly challenged to align responsive undergraduate nursing curricula to rapidly changing healthcare environments. In future-proofing nurse education, educators need to collectively examine ways of interconnecting and developing gerontological and cultural competence within undergraduate curricula. However, there is limited guidance as to how this can be achieved in already compacted curricula. We suggest that this could be achieved by critically examining undergraduate curricula to make explicit how they can be adapted to educate nurses in the provision of culturally competent person-centred care. This approach could help nurse educators adapt student nurse preparation to meet the needs of culturally diverse older people and their families.The routine use of antibiotics for prevention of disease in neonatal lambs has been highlighted as inappropriate, yet research suggests that many farmers in the UK still carry out this practice. The aim of the study was to understand farmers' naturalistic decision-making around prophylactic antibiotic use in lambs. Data from 431 posts by 133 different users of an online discussion forum were analysed quantitatively using natural language processing and qualitatively using a grounded theory approach. Results from the qualitative analysis identified five categories that influenced farmers risk perceptions around prophylactic antibiotic use in lambs anticipated regret, negative emotions and experiential avoidance; economic considerations; farmer identity; perception of capability; and perception of social judgement. Natural language processing analysis of the posts by the study group were compared to posts on topics unrelated to antibiotic use by control groups from the same forum to understand the underlying stto control neonatal disease without antibiotics during busy periods and this was exacerbated by external economic constraints. For farmers' who used antibiotics for therapeutic use, fear of social judgement was an important factor in their perceptions of risk around antibiotic use. The high frequency of negations and conjunctions suggested feelings of moral duty. As such, antibiotic use has developed into a symbol of their good farming identity which conflicted with the identity held by those who used antibiotics prophylactically. These results can be used to inform knowledge exchange around prophylactic antibiotic use in lambs to improve antibiotic stewardship in the sheep farming sector.Since the emergence of SARS-CoV-1 (2002), novel coronaviruses have emerged periodically like the MERS- CoV (2012) and now, the SARS-CoV-2 outbreak which has posed a global threat to public health. Although, this is the third zoonotic coronavirus breakout within the last two decades, there are only a few platforms that provide information about coronavirus genomes. None of them is specific for the virulence glycoproteins and complete sequence-structural features of these virulence factors across the betacoronavirus family including SARS-CoV-2 strains are lacking. Against this backdrop, we present DBCOVP (http//covp.immt.res.in/), the first manually-curated, web-based resource to provide extensive information on the complete repertoire of structural virulent glycoproteins from coronavirus genomes belonging to betacoronavirus genera. The database provides various sequence-structural properties in which users can browse and analyze information in different ways. Furthermore, many conserved T-cell and B-cell epitopes predicted for each protein are present that may perform a significant role in eliciting the humoral and cellular immune response. The tertiary structure of the epitopes together with the docked epitope-HLA binding-complex is made available to facilitate further analysis. DBCOVP presents an easy-to-use interface with in-built tools for similarity search, cross-genome comparison, phylogenetic, and multiple sequence alignment. DBCOVP will certainly be an important resource for experimental biologists engaged in coronavirus research studies and will aid in vaccine development.

Social relationships may serve as both protective factors and risk factors for opioid use (nonmedical prescription opioid or illicit opioid use) among patients receiving methadone for opioid use disorder (OUD). Yet little is known about how relationship quality is linked to outcomes among couples receiving methadone. We evaluated the links between relationship quality and risk of opioid use among couples in which both partners received methadone.

Participants included 53 heterosexual married or cohabiting couples aged 18 and older who were drawn from two opioid treatment programs in Rhode Island and Massachusetts. Both members of the couple completed a self-administered survey assessing their sociodemographic information, relationship and treatment characteristics, and risk of opioid use.

Roughly half of women (47.2%) and men (52.8%) had a moderate to high risk of nonmedical prescription opioid use and almost two-thirds (64.2%) had a moderate to high risk of street opioid use. Risk of street opioid use was highly correlated within couples. Actor-partner interdependence models revealed that when women reported higher positive relationship quality, they had a lower risk of nonmedical prescription opioid use and their partners had a lower risk of street opioid use. Negative relationship quality was not significantly linked to risk of opioid use.

Couples in which both partners receive methadone for OUD may be at risk of return to use, and positive partner relationships may play a role in lowering this risk. Women's perceptions of relationship quality might be a particularly important target for clinical care and interventions.
