Introduction: Average national dropout rates of participants enrolled in a research trial are reported to be 30%. Factors contributing to loss of stroke patient retention include the lack of understanding of study expectations, lack of relationship building between patient and clinical research team, and inefficient management processes. There has been little research into interventions to improve retention. Focusing on these 3 factors may increase the likelihood of stroke patients adhering to and completing participation in stroke trials. The University of Utah Stroke Center became a StrokeNet regional coordinating center in October 2013. As study trials increased, we recognized the need to implement new trial management strategies and did so in January 2016. Methods: Stroke trial metrics were compared between the pre-implementation period (7/1/2012 - 12/31/2015) and a post-implementation period (1/7/2016 - 7/1/2019). The size of clinical research team personnel remained the same across the two periods: 4 coordinators and 9 physicians. Standardization of enrollment processes in stroke trials occurred during the post-implementation period. Three key aspects addressed in the post-implementation period were building rapport, setting realistic expectations, and properly educating patient and family members. The clinical research team incorporated these factors when approaching patients regardless of type of stroke trial (acute, subacute, or observational). Results: During the pre-implementation period, the Stroke Center research team managed 8 stroke studies with 52 patients consented with average trial duration of 23 months (SD); in the post-implementation period, there were 15 studies with 99 patients consented, with average trial duration of 22 months (SD). Retention improved after the intervention from a mean (SD) retention rate of 79.5 (29.7) %. to 90.8 (17.2) %. Although this difference was not significant, it represented meaningful change to the research staff and helped us achieve StrokeNet retention goals. Conclusion: Implementation of effective management strategies leads to higher retention rates of stroke patients despite no change in the size of the clinical research team.

Abstract Background Recent evidence confirms that mesenchymal stem cells (MSCs) facilitate angiogenesis mainly through paracrine function. Extracellular vesicles (EVs) are regarded as key components of the cell secretome, possessing functional properties of their source cells. Subsequently, MSC-EVs have emerged as a novel cell-free approach to improve fat graft retention rate. Objectives To provide a systematic review of all studies reporting the use of MSC-EVs to improve graft retention rate. Methods A systematic search was undertaken using the Embase, PubMed and the Cochrane Central Register of Controlled Trials databases. Outcome measures included donor/receptor organism of the fat graft, study model, intervention groups, evaluation intervals, EV research data, in vitro and in vivo results. Results Of the total 1717 articles, 62 full-texts were screened. Seven studies reporting on 294mice were included. Overall, EV treated groups showed higher graft retention rates compared to untreated groups. Notably, retention rate was similar following EV- and MSC-treatment. In addition to reduced inflammation, graft enrichment with EVs resulted in early revascularization and better graft integrity. Interestingly, hypoxic preconditioning of MSCs improved their beneficial paracrine effects and led to a more proangiogenic EV population, as observed by both in vitro and in vivo results. Conclusions MSC-EVs appear to offer an interesting cell-free alternative to improve fat graft survival. While their clinical relevance remains to be determined, it is clear that not the cells, but their secretome is essential for graft survival. Thus, a paradigm shift from cell-assisted lipotransfer towards ‘secretome-assisted lipotransfer’ is well on its way.

Abstract Background Intravenous thrombolysis (IVT) with alteplase is the first-line therapy for acute ischemic anterior and posterior circulation strokes (ACS and PCS). Knowledge about safety and efficacy of IVT in posterior circulation stroke is deficient as most of the Egyptian studies either assessed IVT outcome in comparison to conservative therapy or its outcome in anterior circulation stroke only. Therefore, our aim was to compare the relative frequency and outcome after intravenous thrombolysis in anterior versus posterior circulation stroke patients presenting to stroke centers of Ain Shams University hospitals (ASUH). Results A total of 238 anterior circulation stroke and 61 posterior circulation strokes were enrolled, onset-to-door and door-to-needle time were statistically insignificant. NIHSS showed comparable difference at all time points despite higher scores along anterior circulation stroke; 90-day modified Rankin Scale (mRS) showed significant improvement in both groups from mRS >2 to ≤2 with a better percentage along posterior circulation stroke patients. There was insignificant difference for either incidence of death or intracranial hemorrhage (ICH) between the two groups. Conclusion IVT significantly reduced NIHSS for both anterior and posterior circulation stroke along different studied time points. Meanwhile, a higher percentage of patients with posterior circulation stroke had a better mRS outcome at 90 days.

Abstract Purpose Mechanical thrombectomy (MT) is the first-line treatment in acute stroke patients presenting with large vessel occlusion (LVO). The efficacy of intravenous thrombolysis (IVT) prior to MT is being contested. The objective of this study was to evaluate the efficacy of MT without IVT in patients with no contraindications to IVT presenting directly to a tertiary stroke center with acute anterior circulation LVO. Materials and Methods We collected the data of 106 acute stroke patients who underwent MT in a single high-volume stroke center. Patients with anterior circulation LVO eligible for IVT and directly admitted to our institution who subsequently underwent MT were included. We recorded baseline clinical, laboratory, procedural, and imaging variables and technical, imaging, and clinical outcomes. The effect of intravenous thrombolysis on 3-month clinical outcome (mRS) was analyzed with univariate tests and binary and ordinal logistic regression analysis. Results Fifty-eight out of the 106 patients received IVT + MT. These patients had 2.6-fold higher odds of poorer clinical outcome in mRS shift analysis (p = 0.01) compared to MT-only patients who had excellent 3-month clinical outcome (mRS 0–1) three times more often (p = 0.009). There were no significant differences between the groups in process times, mTICI, or number of hemorrhagic complications. A trend of less distal embolization and higher number of device passes was observed among the MT-only patients. Conclusions MT without prior IVT was associated with an improved overall three-month clinical outcome in acute anterior circulation LVO patients.

Abstract Background A near-fall is defined as a loss of balance that would result in a fall if sufficient balance recovery manoeuvres are not executed. Compared to falls, near-falls and its associated balance recovery manoeuvres have been understudied. Older adults may not recognise a near-fall or identify the use of their balance recovery manoeuvres to prevent a fall. The consensus on the methods to collect near-fall data is lacking. The primary objective of this study was to determine the feasibility of recruitment and retention. Secondary objectives were to establish evidence that Singapore community-dwelling older adults can identify near-falls and associated balance recovery manoeuvres. Texting and calling methods were explored as reporting methods. Methods This study took place in Singapore (September to October 2019). Participants were healthy, community-dwelling adults aged 65 or older. Recruitment was done through poster advertisement, and all participants gave informed consent. Participants attended a briefing session and reported their near-fall or fall incidence over 21 days using either daily texting or calling. The primary outcome measures were the recruitment rate, retention rate, preferred modes for data reporting and ability to report near-falls or falls. Secondary outcomes included the self-reported incidence of falls and near-falls. Results Thirty older adults were recruited in 5 weeks. All participants completed the study. They understood near-fall concepts and were able to report the occurrence and relevant balance recovery manoeuvres used to prevent a fall. 87% (26/30) chose to text while 13% (4/30) selected calling as their reporting method. One actual fall (0.16%) out of 630 responses was reported. Thirty-six incidents (5.7%) of near-falls were recorded. Sixteen participants (53.3%) experienced near-falls and half of this group experienced two or more near-falls. The use of reach-to-grasp strategy (36%), compensatory stepping (52.8%), and other body regions (11.2%) were used to prevent the fall. Conclusions The study provided evidence that studying near-falls in Singapore community-dwelling older adults is feasible and can be applied to a large-scale study. Recruitment and retention rates were good. Older adults were able to identify near-falls and balance recovery manoeuvres. Both texting and calling were feasible reporting methods, but texting was preferred. Trial registration ClinicalTrials identifier: NCT04087551. Registered on September 12, 2019

Living With Hiv

Persons living with HIV (PLWH) continuously experience symptom burdens. Their symptom prevalence and severity are also quite different. Mobile health (mHealth) applications (apps) offer exceptional opportunities for using personalized interventions when and where PLWH are needed. This study aimed to demonstrate the development process of the symptom management (SM) app and the structure and content of it. Our research team systematically searched for evidence-based resources and summarized up-to-date evidence for symptom management and health education. Our multidisciplinary research team that included physicians, nurses, software engineers, and nursing professors, evaluated the structure and content of the drafted app. Both quantitative data and qualitative results were collected at a group discussion meeting. Quantitative data were scores of sufficient evidence, situational suitability, practicability, cost-effectiveness, and understandability (ranged from one to four) for 119 items of the app contents, including the health tracking module, the self-assessment module, coping strategies for 18 symptoms (80 items), medication management, complementary therapy, diet management, exercise, relaxation techniques, and the obtaining support module. The SM app was comprised of eight modules and provided several personalized symptom management functions, including assessing symptoms and receiving different symptom management strategies, tracking health indicators, and communicating with medical staff. The SM app was a promising and flexible tool for HIV symptom management. It provided PLWH with personalized symptom management strategies and facilitated the case management for medical staff. Future studies are needed to further test the app’s usability among PLWH users and its effects on symptom management.

Objectives. Extended time in the emergency department (ED) has been related to adverse outcomes among stroke patients. We examined the associations of ED nursing shift change (SC) and length of stay in the ED with outcomes in patients with intracerebral hemorrhage (ICH). Methods. Data were collected on all spontaneous ICH patients admitted to our stroke center from 7/1/08–6/30/12. Outcomes (frequency of pneumonia, modified Rankin Scale (mRS) score at discharge, NIHSS score at discharge, and mortality rate) were compared based on shift change experience and length of stay (LOS) dichotomized at 5 hours after arrival. Results. Of the 162 patients included, 60 (37.0%) were present in the ED during a SC. The frequency of pneumonia was similar in the two groups. Exposure to an ED SC was not a significant independent predictor of any outcome. LOS in the ED ≥5 hours was a significant independent predictor of discharge mRS 4–6 (OR 3.638, 95% CI 1.531–8.645, and P = 0.0034) and discharge NIHSS (OR 3.049, 95% CI 1.491–6.236, and P = 0.0023) but not death. Conclusions. Our study found no association between nursing SC and adverse outcome in patients with ICH but confirms the prior finding of worsened outcome after prolonged length of stay in the ED.

Background Functional outcome post-stroke depends on time to recanalization. Effect of in-hospital delay may differ in patients directly admitted to a comprehensive stroke center and patients transferred via a primary stroke center. We analyzed the current door-to-groin time in Germany and explored its effect on functional outcome in a real-world setting. Methods Data were collected in 25 stroke centers in the German Stroke Registry-Endovascular Treatment a prospective, multicenter, observational registry study including stroke patients with large vessel occlusion. Functional outcome was assessed at three months by modified Rankin Scale. Association of door-to-groin time with outcome was calculated using binary logistic regression models. Results Out of 4340 patients, 56% were treated primarily in a comprehensive stroke center and 44% in a primary stroke center and then transferred to a comprehensive stroke center (“drip-and-ship” concept). Median onset-to-arrival at comprehensive stroke center time and door-to-groin time were 103 and 79 min in comprehensive stroke center patients and 225 and 44 min in primary stroke center patients. The odds ratio for poor functional outcome per hour of onset-to-arrival-at comprehensive stroke center time was 1.03 (95%CI 1.01–1.05) in comprehensive stroke center patients and 1.06 (95%CI 1.03–1.09) in primary stroke center patients. The odds ratio for poor functional outcome per hour of door-to-groin time was 1.30 (95%CI 1.16–1.46) in comprehensive stroke center patients and 1.04 (95%CI 0.89–1.21) in primary stroke center patients. Longer door-to-groin time in comprehensive stroke center patients was associated with admission on weekends (odds ratio 1.61; 95%CI 1.37–1.97) and during night time (odds ratio 1.52; 95%CI 1.27–1.82) and use of intravenous thrombolysis (odds ratio 1.28; 95%CI 1.08–1.50). Conclusion Door-to-groin time was especially relevant for outcome of comprehensive stroke center patients, whereas door-to-groin time was much shorter in primary stroke center patients.

Introduction: Patient dissatisfaction and medication non-compliance correlate with patient misunderstanding of their medications and care plan. We aimed to assess the degree of these gaps and their associations in hospitalized stroke patients. Methods: A 5-question survey was administered to patients hospitalized on the neuroscience ward of a comprehensive stroke center. Patient understanding of their condition leading to admission, care plan, medications, primary attending physician, and follow-up plan was assessed. If the patient was unable to communicate, then their health care representative was interviewed. Results: A total of 146 patients (55 stroke and 91 general neurology and neurosurgery (non-stroke) patients) or their representatives were interviewed. Stroke patients were less likely to properly identify their primary attending physician (33/55 (60.0%) stroke patients versus 35/91 (38.5%) non-stroke patients; p=0.011). Inability to identify the attending physician was associated with lack of medication and care plan knowledge and was more common in stroke patients, (23/33 (69.7%) stroke patients versus 14/35 (40.0%) non-stroke patients; p=0.014). Conclusion: Despite sharing a common pool of providers, the inability to identify the primary attending physician was significantly more common in stroke patients and was associated with patient knowledge deficits regarding their medication regimen and care plan. This correlation was significantly higher in stroke patients and suggests that stroke patients may require different, extra or more robust communication and education than the general neurology and neurosurgery population. Additionally, emphasis on attending physician identification may improve patient satisfaction and medication compliance.

Background: “Drip-and-ship” denotes patients in whom intravenous (IV) recombinant tissue plasminogen activator (rt-PA) is initiated at the emergency department (ED) of a community hospital, followed by transfer within 24 hours to a comprehensive stroke center. Although drip-and-ship paradigm has the potential to increase the number of patients who receive IV rt-PA, comparative outcomes have not been assessed at a population based level. Methods: State-wide estimates of thrombolysis, associated in-hospital outcomes and mortality were obtained from 2008-2009 Minnesota Hospital Association (MHA) data. Patient numbers and frequency distributions were calculated for state-wide sample of patients hospitalized with a primary diagnosis of ischemic stroke. Patients outcomes were analyzed after stratification into patients treated with IV rt-PA through primary ED arrival or drip-and-ship paradigm. Results: Of the 21,024 admissions, 602 (2.86%) received IV rt-PA either through primary ED arrival (n=473) or drip-and-ship paradigm (n=129). The rates of secondary intracerebral or subarachnoid hemorrhage were higher in patients treated with IV rt-PA through primary ED arrival compared with those treated with drip-and-ship paradigm (8.5% versus 3.1, p=0.038). The in-hospital mortality rate was similar among ischemic stroke patients receiving IV rt-PA through primary ED arrival or drip-and-ship paradigm (5.9% versus 7.0%). The mean hospital charges were $65,669 for primary ED arrival and $47,850 for drip-and-ship treated patients (p<0.001). Conclusions: The results of drip-and-ship paradigm compare favorably with IV rt-PA treatment through primary ED arrival in this state-wide study.

Background and Issues Aggressive management of vascular risk factors reduces stroke rates. It is unknown whether structured nurse-led follow up increases adherence rates for stroke patients after hospital discharge. Purpose The purpose of this program is to improve secondary stroke risk factor management by instituting a nurse-led initiative called Stroke Therapy, Education, Prevention (STEP). Methods The pilot STEP program was based on protocols used for other stroke prevention trials. This nurse-led program includes inpatient initiation and outpatient maintenance of pharmacologic and lifestyle goals for stroke patients. Eligible patients have a non-disabling ischemic stroke or TIA and are without insurance restrictions and live within a distance allowing return to clinic for follow up. Prior to discharge, the STEP nurse completes patient education, and reviews outpatient goals. The STEP nurse makes phone contact with the patient 7-10 days after discharge to review medication compliance and reinforce education. At 30 days post discharge patients are seen in clinic by the STEP nurse where a resting blood pressure (BP) is measured. If the patient does not meet targets (<140 SBP or <130 SBP for DM) medications are adjusted by a stroke neurologist. We undertook a retrospective chart review of a consecutive cohort of patients matched to STEP eligibility criteria to determine whether the program improved retention rates and BP management. Chi-Square analysis was used to compare visit adherence and percentage achieving goal BPs at 30 days. Results In the STEP group 25/32(78%) patients completed the 30 day follow up compared to 14/32 (44%) patients in the historical matched cohort (p=0.0048). Target BP was achieved in 13/25(52%) STEP patients and 5/14 (36%) matched cohort patients (p=0.32) returning to clinic. Overall, target BP was achieved in 13/32 (41%) and 5/32 (16%) respectively (p=0.026). Conclusions In conclusion, follow up adherence and BP management in the group as a whole was better in the nurse-led model and is recommended for secondary stroke prevention. Long term follow up with this model may further increase in-target rates of BP control and other stroke risk factors.
