Aim: This study investigated demographic and clinical risk factors associated with severity in acute ischemic stroke (AIS) patients with a history of coronary artery disease (CAD). Materials & methods: Multivariate logistic regression models were used to determine specific factors associated with worsening or improving neurologic functions among AIS patients with CAD treated in the telestroke. Results: AIS patients with CAD, peripheral vascular disease (OR: 3.995; 95% CI: 1.035–15.413; p = 0.044) and hypertension (OR: 6.056; 95% CI: 1.207–30.374; p = 0.029) were associated with worsening neurologic functions. Conclusion: Our findings suggest the need to develop strategic management to improve the care of AIS patients with a history of CAD that present with hypertension and peripheral vascular disease in the telestroke network.

Introduction Patients are at risk for different outcomes following stroke based on their diastolic blood pressure on admission. In this study, we determine differences in risk factors between patients with DBP < 80 and > = 80 mmHg and then determine which of these risk factors are associated with worsening neurologic outcomes after rtPA administration. Methods A retrospective analysis was performed by looking at demographics, history, and clinical factors that are known risk factors for acute ischemic stroke. Data were obtained from a stroke registry that includes patient data from between 2010 and 2016. Univariate analysis was performed based on presenting diastolic blood pressure group. Patients who did not receive rtPA were excluded from further study and then patients were further divided by NIHSS > = 7 or > 7. Logistic regression was used to further evaluate variables. Odds Ratios with 95% Confidence Intervals (C.I.) were calculated and used to predict worsening neurologic outcomes for stroke patients based on their blood‐pressure group. Results In the population of stroke patients with diastolic blood pressure < 80 mmHg, increasing age (OR = 1.025, 95% C.I. = 1.011 – 1.039 . P‐value = < 0.001), and elevated blood glucose levels (OR = 1.003, 95% C.I. = 1 – 1.006, P‐value = 0.03) were associated with worsening neurologic outcomes. In the diastolic blood pressure group > = 80 mmHg, increasing age (OR = 1.026, 95% C.I. = 1.012 – 1.04. P‐value = < 0.001), history of drug or alcohol abuse (OR = 2.11, 95% C.I. = 1.116 – 3.988, P‐value = 0.022), hypertension (OR = 1.572, 95% C.I. = 1.01 – 2.449, P‐value = 0.035), and increasing heart rate (OR = 1.012, 95% C.I. = 1.012 – 1.022, P‐value = 0.024) were associated with worsening neurologic outcomes. Conclusions This study found that there are significant differences in the clinical factors between patients with a DBP < or > = 80 mmHg with acute ischemic stroke and these groups also had different risk factors for severe stroke after rtPA administration. In both groups, increasing age was associated with worsening neurologic outcomes, while direct admission was associated with improving outcomes. In the DBP < 80 mmHg group, elevated blood glucose levels were associated with worsening neurologic outcomes. In the DBP > = 80 mmHg group, a history of alcohol or drug use and increased heart rate were associated with worsening neurologic outcomes.

It is well known that post-stroke depression might be a negative factor for stroke recovery, however there is limited evidence to establish the link between pre-stroke depression and stroke outcome such motor recovery. The objective is to determine clinical risk factors in ischemic stroke patients with pre-stroke depression that are associated functional ambulatory outcome.Data from acute ischemic patients from a regional stroke registry were collected for consecutive recombinant tissue plasminogen activator(rtPA)-treated acute ischemic stroke patients between January 2010 and June 2016. Logistic regression model was used to predict risk factors that served as predictive variables, while the increase or reduce odds of improvement in ambulatory outcome was considered as the primary outcome. Multicollinearity and possible interactions among the independent variables were analyzed using the variance inflation factor.A total of 1446 patients were eligible for recombinant tissue plasminogen activator (rtPA) and 596 of these patients received rtPA. Of the 596 ischemic stroke patients, 286 patients presented with recent pre-stroke depression, 310 had no pre-stroke depression. Carotid artery stenosis (OR = 11.577, 95% CI, 1.281-104.636, P = 0.029) and peripheral vascular disease (OR = 18.040, 95% CI, 2.956-110.086, P = 0.002) were more likely to be associated with increase odds of improvement in ambulation in patients with no pre-stroke depression treated with rtPA, while antihypertensive medications (OR = 0.192, 95% CI, 0.035-1.067, P = 0.050),previous TIA (OR = 0.177, 95% CI, 0.038-0.818, P = 0.027), and congestive heart failure (OR = 0. 0.160, 95% CI, 0.030-0.846, P = 0.031) were associated with reduced odds of improvement in ambulation. In addition, carotid artery stenosis (OR = 0.078, 95% CI, 0.10-0.614, P = 0.015, congestive heart failure (OR = 0.217, 95% CI, 0.318-0.402, P = 0.030), previous TIA (OR = 0.444, 95% CI, 0.517-0.971, P = 0.012), higher NIHSS scores ((OR = 0.887, 95% CI, 0.830-0.948, P 0.001), and antihypertensive medications (OR = 0.810, 95% CI, 0.401-0.529, P = 0.019) were associated with the reduced odd of improvement in ambulation in an ischemic stroke population with pre-stroke depression treated with rtPA.Our findings indicate that more risk factors were associated with the decreased odds of an improvement in ambulation following thrombolytic therapy in an ischemic stroke population with pre-stroke depression when compared with those without pre-stroke depression. This finding maybe helpful in the development of management strategies to increase the use of thrombolytic therapy for pre-stroke depressed ischemic stroke to increased their eligibility for rtPA.

Background. Age is one of the most important risk factors for stroke, and an estimated 75% of strokes occur in people 65 years old and above. Adults > 75 years of age experience more hospitalizations and higher mortality. In this study, we aimed to investigate how age and various clinical risk factors affect acute ischemic stroke (AIS) severity in two age categories. Methods. This retrospective data analysis study was conducted using data collected from the PRISMA Health Stroke Registry between June 2010 and July 2016. Baseline clinical and demographic data were analyzed for 65–74-year-old patients and those ≥ 75 years of age. Thisstudy aimed to investigate risk factors associated with stroke severity in these two age categories of AIS patients treated in telestroke settings. Results. An adjusted multivariate analysis showed that the acute ischemic stroke (AIS) population of 65–74-year-old patients experiencing heart failure (odds ratio (OR) = 4.398, 95% CI = 3.912–494.613, p = 0.002) and elevated high-density lipoprotein (HDL) levels (OR = 1.066, 95% CI = 1.009–1.126, p = 0.024) trended towards worsening neurological function, while patients experiencing obesity (OR = 0.177, 95% CI = 0.041–0.760, p = 0.020) exhibited improved neurological functions. For the patients ≥ 75 years of age, direct admission (OR = 0.270, 95% CI = 0.085–0.856, p = 0.026) was associated with improved functions. Conclusions. Heart failure and elevated HDL levels were significantly associated with worsening neurologic functions in patients aged 65–74. Obese patients and individuals ≥ 75 years of age who were directly admitted were most likely to exhibit improving neurological functions.

The implementation of an integrated medical neuroscience course by technologically pivoting an in-person neuroscience course to online using an adaptive blended method may provide a unique approach for teaching a medical neuroscience course during the Covid-19 pandemic. An adaptive blended learning method was developed in response to the requirements necessitated by the Covid-19 pandemic. This model combined pedagogical needs with digital technology using online learning activities to implement student learning in a medical neuroscience course for year one medical students. This approach provided medical students with an individually customized learning opportunity in medical neuroscience. The students had the complete choice to engage the learning system synchronously or asynchronously and learn neuroscience materials at different locations and times in response to the demands required to deal with the pandemic. Students' performance in summative and formative examinations of the adaptive blended learning activities were compared with the previous performance obtained the previous year when the contents of the medical neuroscience course were implemented using the conventional "face-to-face" learning approach. While the cohort of our students in 2019 and 2020 changed, the contents, sessions, volume of material, and assessment were constant. This enabled us to compare the results of the 2019 and 2020 classes. Overall, students' performance was not significantly different between the adaptive blended learning and the in-person approach. More students scored between 70% and 79% during the adaptive blended learning compared with in-class teaching, while more students scored between 80% and 89% during the in-person learning than during the adaptive blended learning. Finally, the percentage of students that scored >90% was not significantly different for both Years 2019 and 2020. The adaptive blended learning approach was effective in enhancing academic performance for high-performing medical students. It also permitted the early identification of underachieving students, thereby serving as an early warning sign to permit timely intervention.

Background Specific clinical and demographic risk factors may be associated with improving or worsening neurologic outcomes within a population of acute ischemic stroke (AIS) patients with a history of obstructive sleep apnea (OSA). The objective of this study was to determine the changes in neurologic outcome during a 14-day recovery as it relates to initial stroke severity in AIS patients with OSA. Methods This retrospective study analyzed baseline clinical risk factors and demographic data collected in a regional stroke center from January 2010 to June 2016. Our primary endpoint measure was the National Institutes of Health Stroke Scale (NIHSS) score and our secondary endpoint measures included the clinical factors associated with improving (NIHSS score ≤7) or worsening (NIHSS score >7) neurological outcome. The relative contribution of each variable to stroke severity and related outcome was determined using a logistic regression. The regression models were checked for the overall correct classification percentage using a Hosmer-Lemeshow test, and the sensitivity of our models was determined by the area under the receiver operating characteristic curve. Results A total of 5469 AIS patients were identified. Of this, 96.89% did not present with OSA while 3.11% of AIS patients presented with OSA. Adjusted multivariate analysis demonstrated that in the AIS population with OSA, atrial fibrillation (AF) (odds ratio [OR] = 3.36, 95% confidence interval [CI], 1.289-8.762, P = 0.013) and changes in ambulatory status (OR = 2.813, 95% CI, 1.123-7.041, P = 0.027) showed an association with NIHSS score >7 while being Caucasian (OR = 0.214, 95% CI, 0.06-0.767, P = 0.018) was associated with NIHSS score ≤7. Conclusion In AIS patients with OSA, AF and changes in ambulatory status were associated with worsening neurological outcome while Caucasian patients were associated with improving neurological outcome. Our findings may have significant implications for patient stratification when determining treatment protocols with respect to neurologic outcomes in AIS patients with OSA.

Background The COVID-19 pandemic revealed existing gaps in the medical educational system that is heavily dependent on the presence of medical students and teachers in laboratory and class for instruction. This affects continuity in the implementation of the neuroanatomy component of the medical neuroscience laboratory activities during COVID-19. We hypothesized that pivoting wet laboratory neuroanatomy activities to online using an adaptive flexible blended method might represent an effective approach in the implementation of laboratory neuroanatomy activities during a pandemic. Methods The current study describes an adaptive flexible blended learning approach that systematically mixes virtual face-to-face interaction activities with the online learning of brain structures, and the discussion of clinical cases. Learning materials are delivered through both synchronous and asynchronous modes, and Year 1 medical students learn neuroanatomy laboratory activities at different locations and different times. Student performances in the adaptive flexible blended learning approach were compared with the learning of similar activities during an in-person implementation of neuroscience laboratory activities. Results The results of using this adaptive flexible blended learning approach provided an autonomous independent learning, self-study approach that broadened student performance such that we have more students scoring between 80 and 89%, whereas the in-person learning resulted in most of the students scoring > 90% in the medical neuroscience laboratory activities. Conclusion An adaptive flexible blended learning approach that combined virtual face-to-face instruction using digital technology with online learning of neuroscience laboratory activities provided a unique educational experience for Year 1 medical students to learn neuroscience laboratory activities during the COVID-19 pandemic.

PURPOSE: Empathy tends to decline during medical education, typically beginning in the third year of medical school and often continuing throughout residency and the physician’s medical career. The purpose of this study was to determine if first year medical student empathy is affected by small group interactions with patients with neurological disorders, and to investigate if changes in empathy persisted over time. MATERIALS AND METHODS: Eighty first year medical students participating in a Neuroscience Module interacted with a variety of neurological patients in a small group informational session. Prior to the experience, participants completed the Jefferson Scale of Physician Empathy–Student (JSPE-S) version. After the experience, students completed a post-test JSPE-S questionnaire, and a final post-post-test JSPE-S questionnaire was completed 5 weeks later. Empathy scores were compared with a repeated measures MANOVA. The relationship between gender and empathy, and the effect of the age of the neurological patients on empathy scores were also examined. RESULTS: Empathy scores for seventy-one students who completed the JSPE-S questionnaires were analyzed. Students had significantly higher empathy immediately after the patient interaction experience, and the change in empathy was sustained over the course of 5 weeks (p = 0.015). The age of the neurological patients had a significant effect on empathy scores. There was no significant difference between empathy scores and gender. CONCLUSIONS: This study supports the incorporation of a group patient interaction experience into the medical school curriculum as an inexpensive and practical method of enhancing medical student empathy in a non-clinical setting.

Background This study aims to identify predictors of improvement or deficit progression in ischemic stroke patients with pre-stroke depression and to evaluate the impact of identified predictors on pre-ischemic stroke depressed patients that received thrombolytic therapy. Methods We performed logistic regression analysis to determine demographic and clinical risk factors that are independently associated with clinical improvement or deficits in ischemic stroke patients with pre-stroke depression that received thrombolytic therapy. Multicollinearity effect in the regression models was controlled using variance inflation factors and the fitness of the models was determined using the Hosmer-Lemeshow test. Results A total of 5469 ischemic stroke patients were identified of which 4748 patients were not diagnosed with depression while 721 were diagnosed with pre-stroke depression. After controlling for all variables with multivariate analysis, we found that the female gender (OR = 2.545, 95 % CI, 1.167–5.553, P = 0.019), coronary artery disease (OR = 2.935, 95 % CI, 1.296–6.645, P = 0.01), heart rate (OR = 1.025, 95 % CI, 1.001–1.049, P = 0.044), and improvement in ambulation (OR = 2.161, 95 % CI, 1.076–4.343, P = 0.03) were associated with neurological deficits while antidepressant medication (OR = 0.226, 95 % CI, 0.075‐0.686, P = 0.009), and direct admission (OR = 0.212, 95 % CI, 0.071‐0.636, P = 0.006) were associated with improvements in pre-stroke depressed patients who received recombinant tissue plasminogen activator (rtPA). Conclusions Our findings indicate that neurological deficits or improvements in hemispheric ischemic stroke patients with pre-stroke depression are associated with baseline stroke severity and that a stratification based on NIHSS scores.

Background Acute ischemic stroke attack with and without a recent TIA may differ in clinical risk factors, and this may affect treatment outcomes following thrombolytic therapy. We examined whether the odds of exclusion or inclusion for thrombolytic therapy are greater in ischemic stroke with TIA less than 24 h preceding ischemic stroke (recent-TIA) as compared to those without recent TIA or non-TIA > 24 h and less than 1 month (past-TIA). Methods A retrospective hospital-based analysis was conducted on 6315 ischemic stroke patients, of whom 846 had proven brain diffusion-weighted magnetic resonance imaging (DW-MRI) of an antecedent TIA within 24 h prior to ischemic stroke. The logistic regression model was developed to generate odds ratios (OR) to determine clinical factors that may increase the likelihood of exclusion or inclusion for thrombolytic therapy. The validity of the model was tested using a Hosmer-Lemeshow test, while the Receiver Operating Curve (ROC) was used to test the sensitivity of our model. Results In the recent-TIA ischemic stroke population, patients with a history of alcohol abuse (OR = 5.525, 95% CI, 1.003–30.434, p = 0.05), migraine (OR = 4.277, 95% CI, 1.095–16.703, p = 0.037), and increasing NIHSS score (OR = 1.156, 95% CI, 1.058–1.263, p = 0.001) were associated with the increasing odds of receiving rtPA, while older patients (OR = 0.965, 95% CI, 0.934–0.997, P = 0.033) were associated with the increasing odds of not receiving rtPA. Conclusion In recent-TIA ischemic stroke patients, older patients with higher INR values are associated with increasing odds of exclusion from thrombolytic therapy. Our findings demonstrate clinical risks factors that can be targeted to improve the use and eligibility for rtPA in in recent-TIA ischemic stroke patients.

The two-hit model has been proposed to explain the effects of diabetes on mothers who are already in a putative subclinical damaged state and then undergo neuronal damage during the delivery process. However, the anatomical and pathophysiological mechanisms are not well understood. Our overarching hypothesis in this review paper is that pregnant women who are diabetic have a damaged peripheral nervous system, constituting the “first hit” hypothesis. The delivery process itself—the “second hit”—can produce neurological damage to the mother. Women with diabetes mellitus (DM) are at risk for neurological damage during both hits, but the cumulative effects of both “hits” pose a greater risk of neurological damage and pathophysiological changes during delivery. In our analysis, we introduce the different steps of our concept paper. Subsequently, we describe each of the topics. First, we outline the mechanisms by which diabetes acts as a detrimental variable in neuropathy by focusing on the most common form of diabetic neuropathy, diabetic distal symmetrical polyneuropathy, also known as distal sensorimotor neuropathy. The possible role of macrosomia in causing diabetic neuropathy and obstetric neurological injury is discussed. Second, we describe how vaginal delivery can cause various obstetrical neurological syndromes and pathophysiological changes. Third, we highlight the risk of obstetric neuropathy and discuss anatomical sites at which lesions may occur, including lesions during delivery. Fourth, we characterize the pathophysiological pathways involved in the causation of diabetic neuropathy. Finally, we highlight diabetic damage to sensory vs. motor nerves, including how hyperglycemia causes different types of damage depending on the location of nerve cell bodies.

ObjectiveThe current study investigates sex differences associated with pharmacological and demographic characteristics in Alzheimer patients (AD) with dementia (ADD) or mild cognitive impairment (MCI).MethodA retrospective analytical approach was used to analyze data from 45,696 AD patients with MCI or ADD. The univariate analysis was used to determine differences in demographic, and pharmacological characteristics for male and female ADD and MCI-AD patients. Multivariate analysis was used to predict specific pharmacological and demographic factors that are associated with male and female MCI and ADD patients.ResultIn the adjusted analysis for male patients, Hispanics [0.166,0.020 – 1.355, P = 0.094] or African Americans [OR = 2.380, 95% CI,2.120 – 2.674, P < 0.001], were more likely to have MCI-AD and be treated with galantamine [OR = 0.559, 95% CI, 0.382 – 0.818, P = 0.003], donepezil [OR = 1.639, 95% CI,1.503 – 1.787, P < 0.001], rivastigmine [OR = 1.394, 95% CI,1.184 – 1.642, P < 0.001], olanzapine [OR = 2.727, 95% CI,2.315 – 3.212, P < 0.001], risperidone [OR = 2.973, 95% CI,2.506 – 3.526, P < 0.001], present with increasing age [1.075,1.071 – 1.079, P < 0.001], and are on tobacco use [OR = 1.150, 95% CI,1.054 – 1.254, P = 0.002]. For female patients, buspirone [OR = 0.767, 95% CI, 0.683 – 0.861, P < 0.001] and a history of alcohol (ETOH) use [OR = 0.484, 95% CI, 0.442 – 0.529, P < 0.001] were associated with MCI-AD. Increasing age [OR = 1.096, 95% CI, 1.093 – 1.100, P < 0.001], donepezil [OR = 2.185, 95% CI, 2.035 – 2.346, P < 0.001], memantine [OR = 2.283, 95% CI, 2.104 – 2.477, P < 0.001] aripiprazole [OR = 1.807, 95% CI, 1.544 – 2.113, P < 0.001] olanzapine [OR = 2.289, 95% CI, 1.986 – 2.640, P < 0.001] risperidone [OR = 2.548, 95% CI, 2.246 – 2.889, P < 0.001] buspirone [OR = 0.767, 95% CI, 0.683 – 0.861, P < 0.001] escitalopram [OR = 1.213, 95% CI,1.119 – 1.315, P < 0.001] African Americans [OR = 1.395, 95% CI, 1.268 – 1.535, P < 0.001] and tobacco use [OR = 1.150, 95% CI, 1.073 – 1.233, P < 0.001] were associated with ADD.ConclusionOur findings reveal that MCI-AD patients were more likely to be Hispanics or African American males treated with rivastigmine, olanzapine and citalopram. African American females were associated with ADD and more likely to be treated with buspirone and presented with a history of ETOH. This finding suggests the need for a pharmacological treatment approach encompassing sex-sensitive strategies for MCI-AD and ADD patients.

Background: Whether gender differences exist in late-onset of Alzheimer’s disease (LOAD) treated with cholinesterase inhibitors (ChEIs) is not fully understood. This study investigated demographic and pharmacological characteristics in LOAD patients to determine gender differences in LOAD patients treated with ChEIs alone and ChEIs with other medications. Methods: This 5-year retrospective data analysis included 9290 LOAD AD patients with 2949 men patients and 6341 women. Potential predictors of demographic and pharmacological characteristics associated gender differences in patients treated with and without ChEIs therapy were determined using univariate analysis, while multivariable models adjusted for demographic and pharmacological variables. Results: In the adjusted analysis, men patients with LOAD that presented with a history of alcohol use (ETOH) (OR = 1.339, 95% CI, 1.072–1.672, p = 0.010), treated with second generation antipsychotics (SGAs) (OR = 1.271, 95% CI, 1.003–1.610, p = 0.047), citalopram (OR = 5.103, 95% CI, 3.423–7.607, p < 0.001), memantine (OR = 4.409, 95% CI, 3.704–5.249, p < 0.001), and buspirone (OR = 2.166, 95% CI, 1.437–3.264, p < 0.001) were more likely to receive ChEIs therapy, whereas older men were less likely to be treated with ChEIs therapy. Women who were African Americans (OR = 1.387, 95% CI, 1.168–1.647, p < 0.001), that received memantine (OR = 3.412, 95% CI, 3.034–3.837, p < 0.001), selective serotonin reuptake inhibitor (SSRIs) (OR = 1.143, 95% CI, 1.016–1.287, p = 0.026), and a history of ETOH (OR = 2.109, 95% CI, 1.724–2.580, p < 0.001) were more likely to receive ChEIs therapy, whereas older women were less likely to receive ChEIs therapy. Conclusion: In both men and women patients, those with increasing age were less likely to be treated with ChEI therapy, while patients treated with memantine were also likely to receive ChEI therapy. Our findings highlight the importance for clinicians to optimize ChEI in LOAD to improve treatment effectiveness and eliminate gender differences in ChEI therapy.

Introduction : Alzheimer dementia (AD) has been reported in both men and women. However, factors contributing to gender differences are not fully understood. We tested the hypothesis that specific pharmacological, demographic, and risk factors contribute to gender difference in AD. Methods : A retrospective analytical approach was used to analyze data from 12,632 AD patients, comprising 4,584 men and 8,048 women. Univariate and multivariate analyses determined the factors contributing to the gender difference in AD patients. Results : About 36% of AD patients were men, and 64% were women. Citalopram (OR = 1.187, 95% CI, 1.044 – 1.350, P = 0.009) was associated with men, while escitalopram (OR = 1.213, 95% CI, 1.119 – 1.315, P Conclusions : Our findings reveal similarities and differences in factors associated with both men and women AD patients, suggesting the development of management strategies for the care of AD.

Introduction : Several studies have investigated gender differences in patients with Lewy Body Dementia (LBD), however, whether the observed differences are associated with demographic and pharmacological factors is not fully understood. The current study tested the hypothesis that specific demographic or pharmacological factors may contribute to the observed gender difference. Methods : A 5‐year data collected from a regional registry from 608 LBD patients including 332 men and 276 women were analyzed. Factors associated with men and women patients with LBD were determined using the logistic regression model. Multicollinearity was evaluated using variance inflation factors (VIFs), with values greater than five suggestive of multicollinearity Results : The results indicate that Caucasian men (94.3% vs 83.3%) were more likely to present with LBD. In the adjusted analysis, increasing age (OR = 1.042, 95% CI, 1.025‐ 1.058, P ˂ 0.001) was more likely to be associated with women with LBD, while olanzapine (OR = 2.871, 95% CI, 1.902‐4.334, P˂ 0.001), buspirone (OR = 2.388, 95% CI, 1.527‐3.735, P˂ 0.001), escitalopram (OR = 1.444, 95% CI, 1.079‐1.932, P = 0.014) and tobacco use (OR = 1.424, 95% CI, 1.075‐1.887, P = 0.014) were associated with men with LBD Conclusions : More men presented with LBD compared to women. Our findings reveal specific demographic and pharmacological factors that contribute to gender differences among LBD patients.

Introduction : Age is the single most important risk factor for stroke and an estimated 75% of all strokes occur in people >65 years of age. In addition, adults >75 years’ experience more hospitalization stays and higher mortality rates with an estimated 50% in the occurrence of all strokes. Several comorbidities have been linked to an increased risk and severity of acute ischemic stroke (AIS). How these factors differentially contribute to the severity of stroke in patients ages >65 and Methods : This retrospective data analysis study was conducted using the data collected from the PRISMA Health Stroke Registry between 2010 and 2016. Baseline clinical and demographic data for patients ages >65 and Results : Adjusted multivariate analysis showed that AIS population of patients >65 and Conclusions : Age is a strong risk factor for AIS, and aged stroke patients have higher morbidity and worsening functional recovery than younger patients. In this study, we observed differences in stroke risk factor profiles for >65 and 65 and

Implementing educational activities, such as a wet lab with cadaveric brain dissection, is known to have a direct impact on medical students' motivation. These activities demonstrate the clinical relevance of concepts taught in the classroom setting. The correlation between motivation and academic performance is not clear. First year medical students participated in wet lab activities. The wet lab included cadaveric dissection of the surface and internal anatomy of the brain, as well as discussions facilitated by the neuroscience faculty and clinicians. Discussions were centered around the clinical relevance of the neuroanatomical features dissected during the wet laboratory activities. Following completion of the laboratory activities, students completed a survey, which was used to assess the students' motivation for learning neuroanatomy based on the Attention, Relevance, Confidence, Satisfaction (ARCS) model of motivation. These results were then correlated with performance on a laboratory examination that tested three-dimensional and cross-sectional knowledge of neuroanatomy and practical skills including the use of imaging techniques. The total mean score of motivation was generally high for all categories of ARCS model of motivation (4.26/5) and was highest for Relevance (4.46/5). When these results were correlated with students' performance on the lab examination, a positive correlation between students' motivation and lab examination scores was found (R2 = 0.877). Implementation of the neuroanatomy cadaveric dissection lab led to increased student motivation, which was positively correlated with students' academic performance. Clin.

Fundamental signs of epigenetic effects are variations in the expression of genes or phenotypic traits among isogenic mates. Therefore, genetically identical animals are in high demand for epigenetic research. There are many genetically identical animals, including natural parthenogens and inbred laboratory lineages or clones. However, most parthenogenetic animal taxa are very small in combined epigenetic and drug addiction research. Orconectes rusticus has a unique phylogenetic position, with 2–3 years of life span, which undergoes metamorphosis that creates developmental stages with distinctly different morphologies, unique lifestyles, and broad behavioral traits, even among isogenic mates reared in the same environment offer novel inroads for epigenetics studies. Moreover, the establishment of crayfish as a novel system for drug addiction with evidence of an automated, operant self-administration and conditioned-reward, withdrawal, reinstatement of the conditioned drug-induced reward sets the stage to investigate epigenetic mechanisms of drug addiction. We discuss behavioral, pharmacological and molecular findings from laboratory studies that document a broad spectrum of molecular and, behavioral evidence including potential hypotheses that can be tested with the crayfish model for epigenetic study in drug addiction research.

To investigate clinical risk factors that were associated with gender differences in thrombolysis therapy in stroke patients with incidence of obesity. Retrospective data of obese acute ischemic stroke patients were extracted from a stroke registry between January 2010 and June 2016. Gender differences in exclusion from rtPA or thrombolysis therapy were determined following an adjustment for differences in demographics, clinical risk factors using multiple regression analysis. Significant interactions between variables in the regression models were determined using variance inflation factors. A total of 1105 obese stroke patients were admitted, 549 were excluded from rtPA of which 51.7% were males and 48.3% were females. Among obese male stroke patients, age > 80 years (OR = 1.029, 95% CI, 1.005–1.054, P = 0.016), a history of peripheral vascular disease (OR = 3.008, 95% CI, 0.989–9.153, P = 0.052), and an elevated diastolic blood pressure (OR = 1.018, 95% CI, 1.001–1.035, P = 0.038) were associated with exclusion from rtPA therapy. In obese female stroke patients, coronary artery disease was associated with exclusion from rtPA (OR = 2.478, 95% CI, 1.270–4.836, P = 0.008) while antihypertensive therapy was associated with inclusion for rtPA (OR = 0.326, 95% CI, 0.139–0.764). Elderly obese male stroke patients with elevated diastolic blood pressure, history of peripheral vascular disease, and obese female stroke patients with a history of coronary artery disease were more likely to be excluded from rtPA.

The objective of this study is to determine whether a school-based program that allows middle school students to actively take responsibility of their learning can act as an effective intervention to promote stroke awareness and healthy lifestyle. Middle school students in grades 6, 7, and 8 (ages 11–14) were divided into small groups and participated in a series of interactive learning activities, centered on motivating middle school kids to learn and recognize signs and symptoms of stroke and to learn healthy lifestyle choices. A total of 127 sixth, 113 seventh, and 98 eighth grade students participated in the intervention program. ANOVA found a significant difference in the baseline knowledge of all stroke and healthy life parameters evaluated in the pre-and post-intervention between the 6th, 7th, and 8th grades. Post-hoc analysis revealed a significant change in the performance (P

BACKGROUND: The integration of patient encounters into the first year of the medical school curriculum is known to be of vital importance in the development of critical thinking and communication skills. We investigated whether exposure of first year medical students to patient encounters during a first year medical school neuroscience course result in a high level of motivation associated with the clinical encounter, and whether this high level of motivation translates to higher academic performance as measured by their performance on formative and summative examinations. METHODS: First year medical students interacted with patients presenting with different neurological disorders in a small group informal session. Following the small group interactions with patients, students participated in a large group debriefing session involving discussions with peers, biomedical sciences faculty, and clinicians. Students then completed a survey designed to assess their motivation in correspondence with the Attention, Relevance, Confidence, and Satisfaction (ARCS) model of motivation. These results were then correlated with students’ performance in the neuroscience examinations. RESULTS: The total mean score was high for all categories of the ARCS model of motivation (4.26/5) and was highest for Relevance (4.46/5). When these motivation scores were correlated with students’ performance on the formative and summative examinations, a significant positive correlation was found between motivation and performance on both the formative (r = 0.85) and summative (r = 0.95) neuroscience examinations. CONCLUSION: Encounters with patients presenting with neurological disorders during a first year medical neuroscience course result in a high level of motivation associated with the clinical encounter, and this was positively correlated with their academic performance.

BackgroundAtrial Fibrillation (AF) is a common cardiac arrhythmia and has been identified as a major risk factor for acute ischemic stroke (AIS). Gender differences in the disease process, causative mechanisms and outcomes of AF have been investigated. In the current study, we determined whether there is a gender-based disparity in AIS patients with baseline AF, and whether such a discrepancy is associated with specific risk factors and comorbidities.MethodsBaseline factors including comorbidities, risk and demographic factors associated with a gender difference were examined using retrospective data collected from a registry from January 2010 to June 2016 in a regional stroke center. Univariate analysis was used to differentiate between genders in terms of clinical risk factors and demographics. Variables in the univariate analysis were further analyzed using logistic regression. The adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for each factor were used to predict the increasing odds of an association of a specific comorbidity and risk factor with the male or female AIS with AF.ResultsIn the population of AIS patients with AF, a history of drug and alcohol use (OR = 0.250, 95% CI, 0.497–1.006,P = 0.016), sleep apnea (OR = 0.321, 95% CI, 0.133–0.777,P = 0.012), and higher serum creatinine (OR = 0.693, 95% CI, 0.542–0.886P = 0.003) levels were found to be significantly associated with the male gender. Higher levels of HDL-cholesterol (OR = 1.035, 95% CI, 1.020–1.050,P P = 0.012), and the inability to ambulate on admission to hospital (OR = 2.258, 95% CI, 1.368–3.727,P = 0.001) were associated with females.ConclusionOur findings reveal that in the AIS patients with atrial fibrillation, migraines, HDL, LDL and poor ambulation were associated with females, while drugs and alcohol, sleep apnea, and serum creatinine level were associated with male AIS patients with AF. Further studies are necessary to determine whether gender differences in risk factor profiles and commodities require consideration in clinical practice when it comes to AF as a risk factor management in AIS patients.

Differences in baseline clinical risk factors have been proposed to contribute to gender differences in stroke outcome, how these clinical risk factors contribute to gender difference in acute ischemic stroke (AIS) patients with obstructive sleep apnea is yet to be fully investigated. This study explored the clinical characteristics associated with gender differences in AIS population with a baseline obstructive sleep apnea(OSA).A retrospective study was conducted using data from 5469 patients with an ischemic stroke event from a regional stroke center collected from January 2010 to June 2016. Multivariate logistic regression was used to determine factors associated with gender differences in the obstructive sleep apnea-ischemic stroke population.A total of 170 AIS patients presented with a baseline OSA, and 101 were men and 69 were women. In the AIS with OSA (AIS-OSA) population, patients presenting with peripheral vascular disease (PVD) (OR = 4.892, 95% CI,1.248 - 19.2, P = 0.023), depression (OR = 3.804, 95% CI, 1.369 - 10.6, P = 0.01), higher BMI (OR = 1.103, 95% CI, 1.036 - 1.18, P = 0.002), and higher HDL levels (OR = 1.125, 95% CI, 1.067 - 1.19, P = 0.001) were associated with increasing odds of being women, and no clinical risk factor was associated with men AIS-OSA patients.A gender specific difference was observed in pre-stroke demographic and risk factors for AIS patients with OSA. Women AIS patients with OSA were more likely to present with PVD and depression and have higher HDL and BMI levels when compared to men within the same population. In addition, more men AIS presented with OSA when compared with women AIS patients. Further studies to explore management strategies to eliminate gender differences will improve outcomes for men and women AIS with OSA.
