The benefit of endovascular stroke therapy (EVT) in large vessel occlusion (LVO) ischemic is highly time dependent. Process improvements to accelerate in-hospital workflows are critical.
Introduction: Current guidelines do not support the use of stenting for severe symptomatic intracranial atherosclerotic disease (ICAD) over maximal medical therapy (MMT) as first line treatment. This is largely due to Stenting and Aggressive Medical Management Therapy Preventing Recurrent Stroke in Intracranial Arterial Stenosis (SAMMPRIS) trial results which featured a high periprocedural stroke rate. In this study, we examined rates ischemic territory qualifying artery (SIT)...
Background: Prior studies have demonstrated that the incidence of stroke and rate infarct progression varies across 24-hour cycle circadian rhythm is associated with brain’s response to reperfusion neuroprotection. However, pathophysiology this variation poorly understood. In study we assessed changes in collateral status time day as a possible mechanism behind variation. Methods: Using data from 7 randomized EVT trials HERMES collaboration, patients analyzable baseline CT angiograms were...
Pastoral camel management practices in Kenya, characterised by free herd mobility that enables efficient utilisation of rangeland resources, is progressively restricted to foraging within the vicinity urban milk market outlets. The emerging peri-urban production system (PUCPS) has potential livelihood benefits households, but adapting responsive demands a challenge with implications for its sustained development. This study assessed marketing PUCPS, guided two research questions. To what...
CT Perfusion (CTP) predictions of infarct core play an important role in the determination treatment eligibility large vessel occlusion (LVO) acute ischemic stroke (AIS). Prior studies have demonstrated that blood glucose can affect cerebral flow (CBF). Here we examine influence and chronic hyperglycemia on CTP estimations core.
Although lingual thyroid gland is the most common benign mass found at junction of anterior two-thirds and posterior one-third tongue, it still a rare clinical entity. This developmental anomaly result an arrested descent anlage early in course embryogenesis. Patients may have symptoms dysphagia due to obstruction or even hemorrhage. These can occur any time from infancy through adulthood. The findings, laboratory tests, radiographic imaging studies employed confirming diagnosis planning...
Background: Understanding the risk factors for loss to follow-up in prospective clinical studies may allow a targeted approach minimizing bias and improving generalizability of conclusions anterior cruciate ligament reconstruction (ACLR) other sports-related interventions. Purpose: To identify independent associated with failure complete (ie, follow-up) patient-reported outcome measures (PROMs) at 2 years after ACLR within well-funded longitudinal cohort. Study Design: Cohort study...
The use of patient-reported outcome measures (PROMs) has become a mainstay orthopedic joint arthroplasty research. Large studies with >1000 participants are vital to research, as they allow for comprehensive multivariable analysis. Achieving high follow-up rates minimizes potential response bias. Maintaining adequate becomes more challenging sample size increases. We aimed systematically review the present literature determine large cohorts/registries total patients and identify factors...
Objective The objective of this study is to find a correlation between internal jugular vein (IJV) and common carotid artery (CCA) diameter ratio central venous pressure (CVP) measurement cut-off value for the IJV/CCA predict low CVP i.e. < 10 cm H20, estimating volume status in critically ill patients. Methods This prospective cross-sectional was conducted at critical care department Shifa International Hospital, Islamabad, from July December 2017. A sample 49 patients ≥ 18 years with...
Background Prehospital routing of patients with large vessel occlusion (LVO) acute ischemic stroke (AIS) to centers capable performing endovascular therapy may improve clinical outcomes. Here, we explore whether distance comprehensive (CSCs), severity, and sex are associated direct‐to‐CSC prehospital in LVO AIS. Methods Results In this cross‐sectional study, identified consecutive AIS from a prospectively collected multihospital registry throughout the greater Houston area January 2019 June...
Due to climate change, irrigated agriculture may become restricted in the mountain valleys northern Pakistan future. Hence, importance of yak (Bos grunniens) keeping ranges as risk-mitigating strategy for dwellers will potentially increase. However, little is known about current status domestic this region. We therefore used phenotypic characteristics and 13 microsatellite loci determine differences level genetic differentiation between populations six valleys. Larger body measures partially...
Tomato production under tunnel structures has shown promising returns in recent years Pakistan. However, the energy use and GHGs dynamics remain largely unknown for tomato controlled conditions. This study estimates budgeting GHG emission off-season (tunnel-farming) production. Study data were gathered from 70 growers through a simple random sampling technique. Energy efficiency, productivity, net along with covariates of output estimated Cob–Douglas regression. The results indicate that...
Abstract In the mountain regions of northern Pakistan, pasture-based animal husbandry is a substantial element people’s livelihood. To study implications herding strategies on rangeland utilization patterns, individual interviews with 90 herders and 10 group five to eight per group, respectively, were conducted in three valleys each Pakistan’s Gilgit-Baltistan region. Data collection targeted number species animals kept, livestock management practices seasonal pasture use included GIS-based...
BACKGROUND: The dynamics of blood clot (combination Hb [hemoglobin], fibrin, and a higher concentration aggregated red cells) formation within the hematoma an intracerebral hemorrhage is not well understood. A quantitative neuroimaging method localized coagulated volume/distribution might improve clinical decision-making. METHODS: deoxyhemoglobin cells extravasated exhibits magnetic susceptibility due to unpaired heme iron electrons. We propose that blood, with cell content, will exhibit (1)...
Intracranial atherosclerosis is a leading cause of stroke with high recurrence rate despite treatment. Numerous factors are proposed to influence due intracranial including lesion eccentricity, plaque characteristics, and computational fluid dynamic metrics, such as wall shear stress. An overlooked variable that intrinsically relates the location arterial segment where occurs. Variations in cerebral blood flow, anatomy, flow dynamics likely drivers initial development thus recurrence. To...
