The actual Coronavirus Disease (COVID 19) pandemic is due to Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a member of the coronavirus family. Besides the respiratory involvement, COVID 19 patients frequently develop a pro-coagulative state caused by virus-induced endothelial dysfunction, cytokine storm and complement cascade hyperactivation. It is common to observe diffuse microvascular thrombi in multiple organs, mostly in pulmonary microvessels. Thrombotic risk seems to be directly related to disease severity and worsens patients' prognosis. Therefore, the correct understanding of the mechanisms underlying COVID-19 induced prothrombotic state can lead to a thorough assessment of the possible management strategies. Hence, we review the pathogenesis and therapy of COVID 19-related thrombosis disease, focusing on the available evidence on the possible treatment strategies and proposing an algorithm for the anticoagulation strategy based on disease severity.Curricular design that addresses residency physician competencies in communication skills and professionalism remains a challenge. Graphic Medicine (GM) uses comics, a medium combining text and images, to communicate healthcare concepts. Narrative Medicine, in undergraduate medical education, has limited reported usage in Graduate Medical Education (GME). Given the time constraints and intensity of GME, we hypothesized that comics as a form of narrative medicine would be an efficient medium to engage residents.The authors created a novel curriculum to promote effective communication and professionalism, focusing on empathy, compassion and cultural competency. A four-week curriculum was delivered in a neurology residency program. Excerpts from non-fiction graphic memoirs about neurological conditions were read, discussed, and paired with prompt-driven drawing exercises. Qualitative surveys were used to assess acceptability of comics, usefulness of comics to convey patient illness experience, and perception of patient needs for physician-patient communication.Ninety-seven percent of residents reported the sessions were a good use of their time. Residents identified new symptoms of neurologic disorders, articulated patient communication needs, and expressed increased empathy after participation. Residents participated in drawing exercises, but these were not formally analyzed. Graphic medicine is a well received format that may build communication skills and increase empathy.
Personalized therapy for patients with COPD requires appropriate choice of drug and delivery device. Inhalers and nebulizers vary in their drug delivery characteristics, particularly the need for passive or active patient inhalation for appropriate drug dispersal and delivery. In this in vitro analysis, we assessed the aerosol performance and drug delivery of two long-acting muscarinic antagonists, glycopyrrolate (GLY; 25µg solution; 1ml) and tiotropium (TIO; 18µg powder) through their respective delivery systems the eFlow® Closed System (CS) vibrating membrane nebulizer and the HandiHaler® dry-powder inhaler (DPI).

The aerosol performances of the eFlow® CS nebulizer and the HandiHaler® were determined using the Next Generation cascade Impactor. The delivered dose of GLY and TIO was determined using different breathing patterns, which varied in tidal volume and peak inspiratory flow rate, respectively, to simulate breathing conditions ranging from normal to severe obstruction.

The therapeutic pipeline includes a growing range of pharmacological interventions that could theoretically intervene with the underlying disease process. It is hoped that applying such interventions in a very early stage of the disease pathology, before the onset of motor symptoms or during its early stages, may prevent or delay further disease progression. To identify people in this early disease stage, criteria for 'prodromal PD' have been proposed-describing people with one or more specific features that jointly constitute a variably increased risk of developing clinically manifest PD. find more Here, we aim to draw lessons from the field of Alzheimer's research, which has followed a similar strategy over the last decade, including the expansion of the disease label to 'prodromal' stages. Importantly, none of the large and costly randomized-controlled trials aiming to slow down or prevent Alzheimer's dementia by targeting the alleged disease pathology, i.e., amyloid-β aggregation, resulted in detectable clinical effects. Lack of sufficiently robust phase 2 trial results before moving to phase 3 studies, suboptimal participant selection, insensitive outcomes, a too narrow target focus, and trial design flaws contributed to this disappointing outcome. We discuss the various similarities between these Alzheimer's and PD approaches, and review the design of prevention or early disease modification trials for both diseases including the potential for immunotherapy. Finally, we offer considerations to optimize the design of such trials in PD, benefiting from the lessons learned in Alzheimer's prevention research.
Symptomatic isolated carotid artery occlusions (ICAO) can lead to disability, recurrent stroke, and mortality, but natural history and best therapeutic management remain poorly known. The objective of this study was to describe our cohort of ICAO patients with an initial medical management.

We conducted a retrospective study including consecutive patients admitted to our Comprehensive Stroke Center for ICAO within 24h after stroke onset between January 2016 and September 2018. Patients with immediate endovascular therapy (EVT) were excluded. Medical treatment was based on anticoagulation (delayed by 24h if intravenous thrombolysis was performed). 'Rescue' EVT was considered if first-week neurological deterioration (FWND) occurred.

Fifty-six patients were included, with a median National Institutes of Health Stroke Scale (NIHSS) of 3. Eleven patients (20%) had FWND during the first week, four benefited from rescue EVT. A mismatch volume > 40cc on initial perfusion imaging and FLAIR vascular hyperintensities were associated with FWND (p = 0.
