Project description:BackgroundHepatitis B virus (HBV) infection disproportionally affects populations in sub-Saharan Africa. Lack of HBV awareness perpetuates disease burden in Africa.ObjectiveTo promote HBV awareness in Tanzania using a systematic, measurable, and expandable approach to educating health care workers (HCW).MethodsWe designed and implemented an HBV knowledge and teaching skills session in southern Tanzania to empower HCWs in leading education to promote disease awareness in their communities. Training was divided into two sessions: didactic and practical. A five-question anonymous survey was distributed in person immediately before and after the practical portion of the training to evaluate HBV knowledge as well as specific skills for teaching. Differences between responses before and after the sessions were evaluated by Chi-Square analysis. A sub-group of questions were further analyzed for differences based on HCW self-report of HBV serostatus awareness.Findings130 HCWs participated in the didactic lecture and 30 HCWs participated in both portions. A pre-post training five-question survey showed an increase in correct answers for all questions, with two showing statistical significance: HBV is silent (7% pre vs. 87% post; p < 0.0001), and repetition as key to promote awareness (63% pre vs. 100% post; p = 0.0002).ConclusionsOur low-cost intervention is applicable to increase HBV awareness in low resource settings across Africa.

Project description:YTH Domain Containing 1 (YTHDC1) is one of the m6A readers that is essential for oocyte development and tumor progression. The role of YTHDC1 in neuronal survival and ischemic stroke is unknown. Here, we found that YTHDC1 was unregulated in the early phase of ischemic stroke. Knockdown of YTHDC1 exacerbated ischemic brain injury and overexpression of YTHDC1 protected rats against brain injury. Mechanistically, YTHDC1 promoted PTEN mRNA degradation to increase Akt phosphorylation, thus facilitating neuronal survival in particular after ischemia. These data identify YTHDC1 as a novel regulator of neuronal survival and modulating m6A reader YTHDC1 may provide a potential therapeutic target for ischemic stroke.

Project description:BackgroundCommunity awareness of stroke, especially the risk factors and warning signs is important in the control of the disease. In sub-Saharan Africa, little is known about community awareness of stroke though the brunt of stroke is currently borne in this region. The aim of the study was to evaluate stroke awareness in Accra (capital city of Ghana) particularly, the risk factors and warning signs.MethodsThis was a cross-sectional study involving systematic sampling of 63 households in each of the 11 sub metropolitan areas of Accra. A structured questionnaire was used to collect stroke awareness data from respondents randomly sampled in the selected households. Logistic regression analyses were done to identify predictors of the main outcome variables including recognition of stroke risk factors, stroke warning signs and the organ affected by stroke.ResultsOnly 40% (n?=?277) of the 693 respondents correctly identified the brain as the organ affected in stroke. Similarly, less than half of the respondents could recognize any of the established stroke risk factors as well as any of the established stroke warning signs. Over 70% (n?>?485) of the respondents either believed that stroke is a preventable disease, or lifestyle alterations can be made to reduce the risk of stroke, or stroke requires emergency treatment. In multivariate analysis, predictors of stroke awareness were: age <50 years (OR?=?0.56, CI?=?0.35-0.92, p?=?0.021), presence of a stroke risk factor (OR?=?2.37, CI?=?1.52-3.71, p?<?0.001) and Christian Religion (OR?=?14.86, CI?=?1.37-161.01, p?=?0.03).ConclusionThough stroke is perceived as a serious and preventable disease in Accra, community awareness of the risk factors and warning signs is sub-optimal. This indicates that community-based education programs to increase public awareness of stroke could contribute to decreasing the risk of stroke and to increasing the speed of hospital presentation after stroke onset.

Project description:The need for a validated set of emotional clips to elicit emotions in more ecological experiments is increasing. Here we present the validation of a new database of emotional films, named E-MOVIE, which includes, in this first validation phase, 39 excerpts arranged in six categories, three negative (Fear, Sadness and Compassion), two positive (Erotic and Scenery) and a Neutral category. Notably, Compassion and Scenery are new in the field as they were not included in other databases. The clips in E-MOVIE are characterized by homogenous durations of approximately two minutes, which make them suitable for psychophysiological research. In order to study the affective profile prompted by each category 174 participants (112 women) rated the movies on multiple dimensions, namely valence and arousal, intensity and discreteness of the induction of one of the six basic emotions and, finally, intensity of the experience of the emotional states defined by a series of emotional adjectives. Erotic clips were effective in the elicitation of a positive emotional state, characterized by high levels of arousal and excitement. On the other hand, Fear clips (selected without blood to avoid disgust reaction) prompted an affect characterized by high arousal, low valence and high levels of reported fear and anxiety. Women reported greater unpleasantness, distress, anxiety and jittery than men to the three negative categories. Compassion clips, characterized by the depiction of crying characters, were able to induce an affective state dominated by sadness and feeling touched, consistent with an empathic reaction to emotional sufferance. Sadness clips, instead, elicited an affective state characterized by sadness together with distress and angst. We also demonstrated that clips depicting natural environments (i.e. Scenery) prompted in the viewer a surprised, inspired affective state, characterized by high valence and arousal (especially in males), a result which suggests that their past categorization as neutral stimuli was inaccurate and problematic.

Project description:Background and purposeTo improve stroke awareness and reduce life-threatening prehospital delays worldwide, a universal stroke educational program is needed. To meet this unmet need, we developed a universal program without language barriers and tested its acceptance in Taiwan, where Chinese is the native language.MethodsStroke 112 was developed using the universal emergency phone number, 112. The numbers imply an emergency and correspond to the 3 stroke recognition signs used in FAST (Face, Arm, Speech, and Time): 1 uneven face (crooked mouth); 1 weak arm (arm weakness); 2 incoherent lips (slurred speech). An online survey was used to determine the acceptance of the Stroke 112 program compared with that of FAST in Chinese. The surveys were delivered using SurveyMonkey (http://www.surveymonkey.com) on 2 separate occasions in Taiwan; in August 2017 for an initial estimation of the acceptance of Stroke 112 and in March 2018, 2 weeks after the official release of Stroke 112 in Taiwan, including a special introductory lecture for neurologists hosted by the STARS-Taiwan (Stroke Treatment and Research Society-Taiwan).ResultsThe initial survey with 465 survey responders, 54.6% thought that Stroke 112 was easier to remember for people in Taiwan compared with FAST (41.2%). After Stroke 112's official release in Taiwan, 610 individuals completed the survey, and the majority (66.4%) thought that Stroke 112 was easier to remember, a significant increase compared with the initial survey (P=0.0001). Among the 130 neurologists who attended the Stroke 112 introductory lecture, 55 completed the online survey. A greater acceptance of Stroke 112 (74.6%) compared with FAST (16.4%) was observed among these 55 neurologists (P=0.0001).ConclusionsStroke 112, a universal stroke educational program without language barriers was developed. It could potentially be implemented worldwide, especially where 112 is used as an emergency phone number.

Project description:Unilateral brain damage following stroke frequently hampers the processing of contralesional space. Whether and how it also affects the processing of stimuli appearing on the same side of the lesion is still poorly understood. Three main alternative hypotheses have been proposed, namely that ipsilesional processing is functionally (i) hyperefficient, (ii) impaired, or (iii) spared. Here, we investigated ipsilesional space awareness through a computerized paradigm that exploits a manipulation of concurrent information processing demands (i.e., multitasking). Twelve chronic right-hemisphere stroke patients with a total lack of awareness for the contralesional side of space were administered a task that required the spatial monitoring of two locations within the ipsilesional hemispace. Targets were presented immediately to the right of a central fixation point (3° eccentricity), or farther to the right toward the screen edge (17° eccentricity), or on both locations. Response to target position occurred either in isolation or while performing a concurrent visual or auditory task. Results showed that most errors occurred when two targets were simultaneously presented and patients were faced with additional task demands (in the visual or auditory modalities). In the context of concurrent visual load, ipsilesional targets presented at the rightmost location were omitted more frequently than those presented closer to fixation. This pattern qualifies ipsilesional processing in right-hemisphere stroke patients as functionally impaired, arguing against the notion of ipsilesional hyperperformance, especially when under visual load.

Project description:We define gaze agency as the awareness of the causal effect of one's own eye movements in gaze-contingent environments, which might soon become a widespread reality with the diffusion of gaze-operated devices. Here we propose a method for measuring gaze agency based on self-monitoring propensity and sensitivity. In one task, naïf observers watched bouncing balls on a computer monitor with the goal of discovering the cause of concurrently presented beeps, which were generated in real-time by their saccades or by other events (Discovery Task). We manipulated observers' self-awareness by pre-exposing them to a condition in which beeps depended on gaze direction or by focusing their attention to their own eyes. These manipulations increased propensity to agency discovery. In a second task, which served to monitor agency sensitivity at the sensori-motor level, observers were explicitly asked to detect gaze agency (Detection Task). Both tasks turned out to be well suited to measure both increases and decreases of gaze agency. We did not find evident oculomotor correlates of agency discovery or detection. A strength of our approach is that it probes self-monitoring propensity-difficult to evaluate with traditional tasks based on bodily agency. In addition to putting a lens on this novel cognitive function, measuring gaze agency could reveal subtle self-awareness deficits in pathological conditions and during development.

Project description:Objective: Acute childhood stroke is an emergency requiring a high level of awareness among first-line healthcare providers. This survey serves as an indicator of the awareness of, the interest in, and knowledge of childhood stroke of German pediatricians. Methods: Thousand six hundred and ninety-seven physicians of pediatric in- and outpatient facilities in Bavaria, Germany, were invited via email to an online-survey about childhood stroke. Results: The overall participation rate was 14%. Forty-six percent of participants considered a diagnosis of childhood stroke at least once during the past year, and 47% provide care for patients who have suffered childhood stroke. The acronym FAST (Face-Arm-Speech-Time-Test) was correctly cited in 27% of the questionnaires. Most commonly quoted symptoms of childhood stroke were hemiparesis (90%), speech disorder (58%), seizure (44%), headache (40%), and impaired consciousness (33%). Migraine (63%), seizure (39%), and infections of the brain (31%) were most frequently named as stroke mimics. Main diagnostic measures indicated were magnetic resonance imaging (MRI) (96%) and computer tomography (CT) (55%). Main therapeutic strategies were thrombolysis (80%), anticoagulation (41%), neuroprotective measures, and thrombectomies (15% each). Thirty-nine percent of participants had taken part in training sessions, 61% studied literature, 37% discussed with colleagues, and 25% performed internet research on childhood stroke. Ninety-three percent of participants approve skill enhancement, favoring training sessions (80%), publications (43%), and web based offers (35%). Consent for offering a flyer on the topic to caregivers in facilities was given in 49%. Conclusion: Childhood stroke constitutes a topic of clinical importance to pediatricians. Participants demonstrate a considerable level of comprehension concerning the subject, but room for improvement remains. A multi-modal approach encompassing an elaborate training program, regular educational publications in professional journals, and web based offers could reach a broad range of health care providers. Paired with a public adult and childhood stroke awareness campaign, these efforts could contribute to optimize the care for children suffering from stroke.

Project description:A limited amount of functional recovery commonly occurs in the weeks and months after stroke, and a number of studies show that such recovery is associated with changes in the brain's functional organization. Measures that augment this reorganization in a safe and effective way may therefore help improve outcome in stroke patients. Here we review some of the evidence for functional and anatomical reorganization under normal physiological conditions, along with strategies that augment these processes and improve outcome after brain injury in animal models. These strategies include counteracting inhibitors of axon growth associated with myelin, activating neurons' intrinsic growth state, enhancing physiological activity, and having behavioral therapy. These approaches represent a marked departure from the recent focus on neuroprotection and may provide a more effective way to improve outcome after stroke.

Project description:ImportanceSelf-awareness of deficits, or the ability to understand the effects of impairments on daily life, is often diminished after a stroke. Diminished self-awareness influences participation in rehabilitation and functional outcomes.ObjectiveTo examine whether self-awareness of deficits changed over time after a stroke (N = 43) and whether metacognitive strategy training (n = 21) resulted in improved self-awareness compared with direct skill training (n = 22).DesignSecondary analysis of data collected from a randomized controlled trial.SettingInpatient stroke rehabilitation.ParticipantsAdults with cognitive impairments after an acute stroke.InterventionMetacognitive strategy training is an approach in which clients are guided through a process of self-assessment and develop solutions for barriers to task performance. This approach was compared with direct skill training, in which the therapist provides specific instructions for task completion, removing the client-initiated assessment and problem-solving components.Outcomes and measuresSelf-awareness measures included the Self-Regulation Skills Interview and Self-Awareness of Deficits Interview at baseline and 3 mo and 6 mo after the intervention. We used a one-way analysis of variance (ANOVA) to analyze change in self-awareness and a two-way ANOVA to examine differences between groups over time.ResultsThere was a statistically significant and potentially meaningful difference over time in the self-awareness domain of strategy behavior, F(2) = 3.35, p = .039, but there were no differences in improvements between the metacognitive strategy and direct skill training groups.Conclusions and relevanceSelf-awareness warrants further investigation to determine whether it improves naturally over time or through both interventions after stroke.What this article addsSelf-awareness of deficits, and the use of strategies in particular, may improve in the early stages of stroke recovery, but the optimal approach for intervention remains unclear.
