Introduction. Strokes and stroke-mimics have been extensively studied in the emergency department setting. Although in-hospital strokes are less studied in comparison to strokes in the emergency department, they are a source of significant direct and indirect costs. Differentiating in-hospital strokes from stroke-mimics is important. Thus, our study aimed to identify variables that can differentiate in-hospital strokes from stroke-mimics. Methods. We present here a retrospective analysis of 93 patients over a one-year period (2009 to 2010), who were evaluated for a concern of in-hospital strokes. Results. About two-thirds (57) of these patients were determined to have a stroke, and the remaining (36) were stroke-mimics. Patients with in-hospital strokes were more likely to be obese (p=0.03), have been admitted to the cardiology service (p=0.01), have atrial fibrillation (p=0.03), have a weak hand or hemiparesis (p=0.03), and have a prior history of stroke (p=0.05), whereas, when the consults were called for “altered mental status” but no other deficits (p<0.0001), it is likely a stroke-mimic. Conclusion. This study demonstrates that in-hospital strokes are a common occurrence, and knowing the variables can aid in their timely diagnosis and treatment.

In-hospital strokes, that is new strokes occurring among hospitalized patients, account for 6.5–15% of all strokes. Compared to community-onset stroke patients, in-hospital stroke patients tend to have worse functional and mortality outcomes. This review addresses the characteristics of acute in-hospital ischemic strokes, reasons these patients have worse outcomes compared to community-onset stroke patients, and future steps to improve outcomes.

Multiple overtracing strokes are common drawing behaviors in freehand sketching; that is, additional strokes are often drawn repeatedly over the existing ones to add more details. This paper proposes a method based on stroke-tolerance zones to group multiple overtraced strokes which are drawn to express a 2D primitive, aiming to convert online freehand sketches into 2D line drawings, which is a base for further 3D reconstruction. Firstly, after the user inputs a new stroke, a tolerance zone around the stroke is constructed by reference to its polygonal approximation points obtained from the stroke preprocessing. Then, the input strokes are divided into stroke groups, each representing a primitive through the stroke grouping process based on the overtraced ratio of two strokes. At last, each stroke group is fitted into one or more 2D geometric primitives including line segments, polylines, ellipses, and arcs. The proposed method groups two strokes together based on their screen-space proximity directly instead of classifying and fitting them firstly, so that it can group strokes of arbitrary shapes. A sketch-recognition prototype system has been implemented to test the effectiveness of the proposed method. The results showed that the proposed method could support online multiple overtracing freehand sketching with no limitation on drawing sequence, but it only deals with strokes with relatively high overtraced ratio.

"Different strokes: differences in the characteristics and outcomes of BCVI and non-BCVI strokes in trauma patients." Trauma Surgery & Acute Care Open 5, no. 1 (September 2020): e000457. http://dx.doi.org/10.1136/tsaco-2020-000457.
BackgroundAlthough strokes are rare in trauma patients, they are associated with worse functional and cognitive outcomes and decreased mobility. Blunt cerebrovascular injury (BCVI)–related strokes and mortality have decreased, likely due to refined screening and treatment algorithms in trauma literature; however, there is a paucity of research addressing non-BCVI strokes in trauma. The purpose of this study is to evaluate the incidence, etiology, and risk factors of stroke in our trauma population in order to identify preventive strategies.MethodsThis study was a retrospective review of all adult trauma patients admitted to a level 1 trauma hospital who suffered a stroke during trauma admission from 2010 to 2017. Data were collected from the prospectively maintained trauma and stroke databases. Stroke etiology was determined by a vascular neurologist.ResultsOf the 43 674 adult trauma patients admitted during the study period, 99 (0.2%) were diagnosed with a stroke during the index admission. Twenty-one (21%) strokes were due to BCVI. Seventy-eight (79%) strokes were due to non-BCVI etiologies. Patients with non-BCVI strokes were older, less severely injured, and had more medical comorbidities compared with patients with a BCVI stroke. While patients with a BCVI stroke were more likely to suffer multiple traumatic injuries from MVC (76% vs 28%, p<0.001), non-BCVI strokes had more isolated extremity injuries from fall mechanism (55% vs 10%, p<0.001). Over the study period, the age and incidence of stroke and BCVI (p<0.001) increased. However, the rate of BCVI strokes decreased while the rate of non-BCVI strokes increased.DiscussionThe incidence of stroke has increased despite aggressive screening and treatment of BCVI. This increase is primarily due to non-BCVI strokes which are associated with advanced age and medical comorbidities after low mechanism traumatic injury. Medical optimization of comorbid conditions during trauma hospitalization will become increasingly important for stroke prevention as the population ages.Level of evidence: Level III

Writing cross stroke examination is one of the difficult and challenging problem in forensic document examination. In this work, we tried to find sequence of order in crossing printed and pen strokes. The study mainly deals with application of chromaticity diagram generated by Video Spectral Comparator (VSC)-6000. Chromaticity co-ordinates are generated from three different points of first, second and cross strokes. When two strokes cross each other, then surface on point of intersection corresponds to second stroke. So, we have started this work with the assumption that chromaticity co-ordinate (x,y) of the crossing stroke should be similar to that of second stroke. We perform our experiment in both homogeneous and heterogeneous crossing strokes. We repeat the same experiment five times by preparing different samples each time to establish more valid conclusion but we get positive and conclusive results only in the case of heterogeneous crossing strokes where printed stroke is above the pen strokes.

This work is performed to establish chronological order in crossing strokes between printed stroke and pen strokes. Nine different types of pens including cello maxriter pen (black and blue), pilot pen (red and black), cello pointec pen (black and blue) and cello techno tip pen (red, black and blue) are used to produce pen strokes and for printed stroke Canon LBP 3300 printer is used. In the case of printed stroke, only black color stroke is applied. As a result, samples of both homogeneous and heterogeneous intersecting strokes are prepared. This work is based on the assumption that nature and peak characteristics of absorption spectra from crossing stroke should be similar to that of second stroke. Here, absorption spectra is generated by Video Spectral Comparator-6000 by using light of wavelength ranging from 400 nm to 1000 nm. From this experiment, it is found to be possible to find chronological order for heterogeneous crossing strokes (crossing stroke of different colors) only if printed stroke is over pen stroke. It means, only if print is done over writing strokes from red and blue pen, then order of sequence of writing can be determined whereas in other cases it is not possible.

Background Many patients with large vessel occlusion (LVO) who are otherwise candidates for endovascular treatment (EVT) have had previous strokes. We aimed to examine the effect of previous stroke on outcome after EVT. Methods Consecutive patients with LVO were prospectively entered into a National Acute Stroke registry of patients undergoing EVT. Patients treated with EVT were divided into those with and without previous strokes. The rates of favorable reperfusion status, mortality, and excellent outcome at 90 days post-stroke as well as symptomatic intracranial hemorrhage (sICH) were evaluated. Results A total of 390 underwent EVT and 35 had previous strokes. Patients with previous strokes were significantly older; more frequently had a history of prior myocardial infarction and more often had pre-existing functional disability. Favorable target vessel recanalization was less frequently achieved in patients with previous strokes (60% vs. 82%; p = 0.005) and ordinal regression analysis for functional outcome revealed higher frequency of deterioration at three months in patients with previous strokes. Nevertheless, 9% of these patients maintained their previous disability state and sICH rates did not differ between the groups. Mortality rates at one year post stroke were significantly higher in patients with previous strokes (37% vs. 16%; p = 0.005). Conclusions Previous strokes are associated with higher likelihoods of mortality and unfavorable outcome in patients with LVO undergoing EVT. However, because some of these patients maintain their previous disability state, the presence of previous stroke should not be used as an exclusion criterion from EVT.

Introduction: Heart disease and cancer are the top two killers in the world, but strokes are the third most common cause of death worldwide. Furthermore, one-third of stroke victims are left with long-term disabilities. An Ischemic-strokes account for 80% of all strokes, while hemorrhagic strokes account for 20% of all strokes. Aim of this study: The main aim of this study is comparing the haemorrhagic and ischemic stroke patients – analysis of mortality, clinical development and relationship between stroke variables. Research Methodology: The design of this research is descriptive and exploratory. The current study included 100 patients with an acknowledged stroke incidence (57 men and 43 women). The difference of statistics between infarct and haemorrhage on the demographic & clinical variables was discovered through the use of univariate and Multivariate analysis. Data analysis: The data have been analyzed on a total of 100 patients based on the two types of strokes using various statistical tools on clinical and demographic variables. Conclusion: It is concluded that in comparison to ischemic stroke, hemorrhagic stroke affected a younger age group. Stroke patients with a history of hypertension had a statistically insignificant link between their hypertensive history and the occurrence of the disease, according to the univariate analysis.

The new clinical construct of embolic stroke of undetermined source (ESUS) suggests that many cryptogenic strokes are related to minor-risk covert embolic cardiac sources or to embolus from non-occlusive plaques in the aortic arch or in the cerebral arteries. The authors analyzed the prevalence of ESUS in a real-life condition in Italy and compared the recurrence rates in cryptogenic strokes, cardioembolic strokes, and ESUS. The authors retrospectively reassessed according to ESUS criteria 391 consecutive admissions in a stroke unit where extensive diagnostic search was routinely performed. Recurrences in each stroke type within a 3-year follow-up period (mean time: 25.44 months - standard deviation: 9.42) were also compared. The prevalence of ESUS in the aforementioned cohort was 10.5%. All ESUS patients received antiplatelet agents. Warfarin was prescribed in 56.9% of cardioembolic strokes. The recurrence rate in ESUS patients was 4.4% per year, slightly higher than in cardioembolic strokes (3.5%) and significantly higher than in cryptogenic non-ESUS (1.2%) (P<0.0001). This is the first description of a cohort of ESUS patients in an Italian stroke unit. Patients with ESUS have a significantly higher risk of recurrence than in those with non-ESUS cryptogenic strokes, and slightly higher than in those with cardioembolic strokes. Results support the hypothesis of a more extensive diagnostic evaluation in cryptogenic strokes and the feasibility of such approach.

This thesis proposes a novel approach to musical software analysis that prescribes testing a given software interface in a wide variety of hardware contexts, each providing unique insights into its design. This work is situated in the general context of graphical software performance, which we define as musical performance through manipulating an on-screen software interface to create music. The analysis strategy is investigated using the Different Strokes (DS) performance environment as a specific example. A series of software extensions to DS were undertaken to extend the application to new hardware contexts and use cases. These include extensions for the use of Different Strokes in an interdisciplinary performance work, d_verse; the adaptation of DS to work on a large multi-touch surface; the integration of a force-feedback input device; and the integration of the libmapper framework, allowing it to be easily interconnected with alternative input and output devices. The thesis also presents a historical overview of graphical software intended for live use, and a background on general issues in interface design for this usage context. An exploratory user test was performed with the force-feedback setup where participants used DS in the presence of simulated physical forces. While there was no clear preference for any of the haptic effects, the different physical forces present are demonstrated to have gestural implications. These kinds of implications should be taken into account when designing mappings from gesture to sound, and in the overall interaction design. Cette thèse propose une nouvelle stratégie d'analyse de logiciels pour la musique par l'utilisation d'interfaces graphiques dans divers contextes matériels informatiques. Notre travail s'inscrit dans la perspective globale de « graphical software performance » définie ici comme la manipulation d'interfaces utilisateur lors de performances musicales. La stratégie d'analyse que nous proposons a été explorée à partir de Different Strokes (DS), un logiciel conçu pour la création musicale. Pour permettre l'utilisation de DS dans plusieurs contextes matériels et contextes d'utilisation nouveaux, nous avons développé un ensemble d'extensions. Ces extensions ont été élaborées, entre autres, pour l'utilisation de DS dans la série de performances interdisciplinaires d_verse. Nous avons également adapté DS pour qu'il soit compatible avec une surface « multi-touch » de grande taille, nous y avons intégré une interface haptique, et nous y avons ajouté libmapper, une bibliothèque logicielle facilitant l'interconnectivité d'interfaces d'acquisition et de restitution. Cette thèse présente, en outre, un survol de l'histoire des logiciels graphiques conçus pour l'usage en direct et une discussion des problèmes liés à la conception d'interfaces utilisateur dans ce contexte précis d'utilisation. Un test exploratoire a été effectué avec le système haptique intégré à DS. Lors du test, les participants ont utilisé Different Strokes en présence de différentes forces physiques simulées. Bien que nous n'ayons pas observé de préférence claire pour l'un ou l'autre des effets haptiques, nous démontrons que les différentes forces physiques présentes influencent néanmoins la gestuelle. Nous concluons que leur influence doit être prise en considération dans la conception de mappings entre le geste et le son et dans la conception d'interaction en général.

Abstract The effects of valve strokes on the spray shapes of a GDI injector with six holes were studied. Two kinds of strokes that change the shapes to be either cone-shaped or bell-shaped were selected to investigate the flow characteristics that caused the shapes to change. Fuel-spray behaviors were first observed with an experimental setup; strokes of 100 percent (full stroke) and 26 percent were selected assuming the multiple injection of fuel. The 26 percent stoke was selected as a representative example of narrow stroke. To investigate the flow characteristics that caused the cone and bell shapes, computational fluid simulation was applied to study the fluid flows around the holes and sprays in the air region. It was found that the stroke of 26 percent formed a narrow space upstream of the hole inlets, so the velocity component in the radial direction at the hole inlets increased. The velocity component in the radial direction also increased at the hole outlets, so each spray plume became wider and the spaces between the plumes narrower. Due to the narrower spaces, the mixture of the plumes caused the spray to become bell-shaped. The velocity component in the radial direction at the hole outlets was an important factor that determined the spray shape in the air region.

American Society of Mechanical Engineers, 2019. http://dx.doi.org/10.1115/detc2019-98481.
Abstract Many engineering design tasks involve creating early conceptual sketches that do not require exact dimensions. Although some previous works focus on automatically generating sketches from reference images, many of them output exactly the same objects as the reference images. There are also models that generate sketches from scratch, which can be divided into pixel-based and stroke-based methods. Pixel-based methods generate sketches as a whole, without any information of the strokes, while stroke-based methods generate sketches by outputting strokes in a sequential manner. Pixel-based methods are frequently used to generate realistic color images. Although the pixel-based methods are more popular, stroke-based methods have the advantages to scale to a larger dimension without losing high fidelity. An image generated from stroke-based methods has only strokes on the canvas, resulting in no random noise in the blank areas of the canvas. However, one challenge in the engineering design community is that most of the sketches are saved as pixel-based images. Furthermore, many non-pixel-based methods rely on stroke-based training data, making them ill-suited for generating design conceptual sketches. In order to overcome these limitations, the authors proposed an agent that can learn from pixel-based images and generate stroke-based images. An advantage of such an agent is the ability to utilize pixel-based training data that is abundant in design repositories, to train stroke-based methods that are typically constrained by the lack of access to stroke-based training data.

Results of the luge athletes strongly depend on the successful start. While number of methods successfully analysed movements around start handles, still there is lack of methods to monitor paddling strokes. Present paper demonstrates smart textile gloves, designed for such a purpose. Developed gloves allow to measure timing of the arms strokes as well as easily distinguish between good stroke, when athlete’s palms are in full contact with ice, and insufficient one, when fingers just slide over ice without providing good push.

Abstract Stroke is the second leading cause of death worldwide, including Brazil¹,2. It is a more common condition in the elderly, but it has an increasing prevalence in young adults due to the development of risk factors that were typically attributed to older ages3. Risk factors can be categorized into non-modifiable (race, ethnicity, gender and age) and modifiable (arterial hypertension, obesity, diabetes mellitus, smoking and alcoholism), both contributing to distinct trends in incidence and mortality from stroke4. There are two pathological subtypes of stroke, the hemorrhagic one that courses with intraparenchymal or subarachnoid hemorrhage, and the ischemic one that involves areas of cerebral, retinal and even spinal infarction5,6. Clinical syndromes and focal neurological deficits are determined by the affected vascular territory, a parameter that is also used to classify strokes, presume prognoses and determine more specific interventions

Wang, Zekun, kangxiang Ji, and Qi Fang. Endovascular thrombectomy for stroke due to acute basilar-artery occlusion: A systematic review and meta-analysis of randomized controlled trials. INPLASY - International Platform of Registered Systematic Review and Meta-analysis Protocols, November 2022. http://dx.doi.org/10.37766/inplasy2022.11.0063.
Review question / Objective: The objective of this systematic review and meta-analysis was to compare the efficacy and safety of endovascular thrombectomy with best medical management for treating patients with acute basilar-artery occlusion. Condition being studied: Posterior circulation stroke (PCS) accounts for approximately a fifth of all strokes. As an important subtype of PCS, acute basilar artery occlusion is relatively rare, causing only 1% of all ischemic strokes and 5% of strokes due to large vessel occlusion. However, acute basilar artery occlusion is assosciated with poor outcomes, high risks of mortality and disability.

Oh, Ju Sun, Yoo Jin Choo, and Min Cheol Chang. Effect of Selective Serotonin Reuptake Inhibitors on Motor Recovery After Stroke: A Systematic Meta-analysis. INPLASY - International Platform of Registered Systematic Review and Meta-analysis Protocols, June 2022. http://dx.doi.org/10.37766/inplasy2022.6.0084.
Review question / Objective: We conducted a meta-analysis to determine the effectiveness of SSRIs in improving motor outcomes after stroke. Condition being studied: Stroke is a major cause of disability, and motor weakness is one of the most disabling and common complications of stroke. It impairs patients’ ability to perform daily activities independently and deteriorates their quality of life. Selective serotonin reuptake inhibitors (SSRIs) have been reported to have a positive effect on motor recovery after stroke, as well as on the prevention or management of post-stroke depression. In contrast, some previous studies have revealed no positive therapeutic effects of SSRIs on motor recovery after stroke. In the current study, to accurately determine the effectiveness of SSRIs for improving motor outcomes after stroke, we only included studies in which SSRIs were administered to patients in the recovery phase after stroke (<6 months after stroke onset).

INPLASY - International Platform of Registered Systematic Review and Meta-analysis Protocols, November 2022. http://dx.doi.org/10.37766/inplasy2022.11.0145.
Review question / Objective: This Systematic review, describes two issues. 1. in the general population, a high TyG index predicts the risk of ischaemic stroke (IS) P: the general population without ischaemic stroke. I: higher TyG index. C: lower TyG index. O: first ischaemic stroke occurrence. S: Observational study. 2.In the ischaemic stroke(IS) population, a high tyg index predicts poor prognostic outcome. P: ischaemic stroke patient population. I: higher TyG index. C: lower TyG index O: death, stroke recurrence, poor functional outcome, deterioration in neurological function. S: Observational study. Information sources: We searched the Cochrane Library, Embase, MEDLINE, Web of Science, PubMed, and other relevant English databases and related websites. In addition, we reviewed the references for inclusion for literature that we may not have retrieved.

Wang, Dou, Tao Li, Jie Rong, Nan Wang, Xianling Fan, and Yongmei Yan. Is fluoxetine necessary for preventive treatment of post-stroke depression in stroke patients? A meta-analysis of randomized controlled trials. INPLASY - International Platform of Registered Systematic Review and Meta-analysis Protocols, March 2022. http://dx.doi.org/10.37766/inplasy2022.3.0137.
Review question / Objective: One third of patients may have post-stroke depression after a stroke. Poststroke depression seriously affects rehabilitation outcome, quality of life and mortality of stroke patients. Data on preventive treatment of fluoxetine for post-stroke depression in this setting are inconsistent. The purpose of this systematic review was to explore the efficacy and acceptability of fluoxetine for early antidepressant therapy in stroke patients, so as to better provide evidence-based medical evidence for clinical practice. To this end, the systematic review to be considered will address the following issues: P: stroke patients; I: Treatment interventions included: fluoxetine (Prozac), control group: conventional treatment, plus placebo or no other intervention; O: Primary outcome: incidence of PSD, secondary outcome: Hamilton Scale, neurological dysfunction, daily living ability, mortality, incidence of adverse reactions; S: This review includes only randomized controlled studies.

Considerations for ensuring safety during telerehabilitation of people with stroke. A protocol for a scoping review. INPLASY - International Platform of Registered Systematic Review and Meta-analysis Protocols, September 2022. http://dx.doi.org/10.37766/inplasy2022.9.0104.
Review question / Objective: To summarise measures or aspects targeted at reducing the incidence of adverse events during the delivery of exercise interventions through telerehabilitation in patients after stroke. Background: The sequelae in people with stroke are diverse. Regarding physical function post-stroke, functional impairment of the upper and lower extremities is common, which may be due to weakness or paralysis, sensory loss, spasticity, and abnormal motor synergies. In addition, a near 15% prevalence of sarcopenia has been found in people with stroke. Gait impairment has been observed in a high percentage of people with stroke, a dysfunction that may persist despite rehabilitation. More than 50% of people with stroke may experience limitations in activities such as shopping, housework, and difficulty reintegrating into community life within 6 months. These restrictions can result in a diminished health-related quality of life.

Effects of repetitive transcranial magnetic stimulation on upper-limb and finger function in stroke patients: a systematic review and meta-analysis of randomized controlled trials. INPLASY - International Platform of Registered Systematic Review and Meta-analysis Protocols, May 2022. http://dx.doi.org/10.37766/inplasy2022.5.0121.
Review question / Objective: P:Adult patients (age ≥ 18 years) diagnosed with stroke based on relevant clinical examination; I:Intervention group with rTMS alone or in combination with other treatments with rTMS; C:Control group received sham treatment or no rTMS; O: Upper extremity function:the Fugl-Meyer Assessment Upper Extremity (FMA-UE); Hand function:box and block test(BBT), nine-hole peg test(NHPT), and Purdue pegboard test(PPT); S:Randomized controlled trials (rather than crossover designs). Condition being studied: In Europe, more than 1 million new cases of stroke are reported each year. The absolute number of stroke patients is expected to increase in the near future due to the progressive aging of the population. Approximately 50-80% of stroke survivors present with upper extremity dysfunction. Recovery of upper extremity function is associated with improvements in activities of daily living and mental health. However, few stroke survivors show full recovery of upper extremity function 6 months after stroke. In addition, rehabilitation has a limited impact on the recovery of hand motor function.

Chang, Ke-Vin. Shoulder Ultrasound Imaging in the Post-stroke Population: a Study Protocol for a Systematic Review and Meta-analysis. INPLASY - International Platform of Registered Systematic Review and Meta-analysis Protocols, December 2022. http://dx.doi.org/10.37766/inplasy2022.12.0075.
Review question / Objective: To investigate sonographic findings in post-stroke hemiplegic shoulders. Rationale: The incidence of post-stroke hemiplegic shoulder pain was high, ranging from 34% to 84%. Uncertainties remain regarding the prevalence, etiologies, and clinical implication of shoulder pathologies after stroke. Ultrasound has emerged as an accessible tool to diagnose diverse soft tissue problems Therefore, we undertake a meta-analysis to provide more rigorous understanding of the structural changes in post-stroke hemiplegic shoulders on ultrasound examination and hopefully to enhance the treatment strategy of hemiplegic shoulder pain.
