RESUMO

Purpose: Evidence supporting secondary stroke in sub-Saharan Africa is scarce. This study describes the incidence of stroke recurrence and associated risk factors in sub-Saharan Africa. Methods and Materials: Scientific databases were systematically searched from January 2000 to December 2022 for population-based observational studies, case-control or cohort studies of recurrent stroke involving adults aged 18 years and above in sub-Saharan Africa (SSA). We assessed the quality of the eligible studies using the Critical Appraisal Skills Program (CASP) checklist for observational studies. Results: Six studies met the inclusion criteria and were included in this study. Stroke recurrence rates in SSA ranged from 9.4% to 25%. Majority of the studies were conducted from Western Africa and showed that stroke recurrence rates are high within sub-Saharan Africa ranging from 2% to 25%. The known stroke risk factors such as hypertension, chronic alcohol consumption, etc., remained the leading causes of stroke recurrence. The studies reported a higher mortality rate ranging from 20.5 -23% among those with recurrent strokes compared to primary strokes. Conclusion: This systematic review is an update and summary of the available literature on stroke recurrence within sub-Saharan Africa. Further studies are warranted to assess the outcomes and burden of stroke recurrence in SSA.

RESUMO

BACKGROUND: Nurses play an essential role in the achievement of quality depicted by the Quintuple Aim to improve clinical outcomes, patient experience, equity, provider well-being, and reduction of costs. When quality gaps occur, practice change is required and is facilitated by quality improvement (QI) and implementation science (IS) methods. QI and IS research are required to advance our understanding of the mechanisms that explain how evidence is implemented and improvements are made. PROBLEM: Despite past efforts of the evidence-based practice and QI movements, challenges persist in sustaining practice improvements and translating research findings to direct patient care. APPROACH: The purpose of this article is to describe the Synergy for Change Model that proposes that both QI and IS research and practice be used to accelerate improvements in health care quality. CONCLUSIONS: Recognizing the synergy of QI and IS practice and research will accelerate nursing's contributions to high-quality and safe care.

RESUMO

Background: Stroke is an inflammatory state that causes death and chronic disability. Inflammation and oxidative stress are a predictor of poor clinical outcome, its effects are controversial and has not been evaluated in Sub-Saharan Africa (SSA). Methods: We conducted a prospective cohort study of CT head confirmed ischemic and hemorrhagic stroke admitted within 7 days of onset of motor weakness. Baseline CRP, NLR and baseline glucose was measured with subsequent modified Rankin Scale (mRS) score on day 14 post-stroke. Cox proportional hazard model was fitted to determine hazard ratios of mortality with CRP, NLR and blood glucose. Results: Out of 120 patients, 51.7% were female, 52.5% had ischemic stroke and the overall median age was 65 (IQR 54-80) years. Nineteen (15.8%) patients died within a median survival time of 7 days, while 32 (25.8%) died by day 14 after stroke. Conclusion: High C-reactive protein and stroke related hyperglycemia conferred statistically significant hazards of mortality among patients with acute and subacute stroke.

RESUMO

PURPOSE: Childhood adversity plays a fundamental role in predicting youth cardiometabolic health. Our understanding of how adverse experiences in childhood should best be conceptualized remains elusive, based on one-dimensional measures of adversity. The present study fills a major gap in existing research by examining two distinct forms of threat and instability-related exposures that may impact cardiometabolic risk (CMR) in adolescence. METHODS: We explore two specific subtypes of adversity: trauma (e.g., badly hurt, victim of crime, loss of close person) and instability (e.g., moving, change of schools, change in household structure) as differential influences that can accumulate to impact early childhood onset of CMR (body mass index, high-density lipoprotein (HDL), low-density lipoprotein, diastolic and systolic blood pressure, triglycerides, C-reactive protein, insulin sensitivity). Secondary data were drawn from a randomized control behavioral trial of youth recruited during sixth grade from urban Cleveland (Ohio) schools beginning in 2012-2014 (n = 360) and followed for 3 years. Participants reported on 12 adverse experiences, six trauma- and six instability-specific. Multiple regression assessed effects of prospective and accumulative indices of trauma and instability with 3-year trajectories of eight objective CMR markers. RESULTS: Instability was associated with increased body mass index, decreased high-density lipoprotein, and increased C-reactive protein slopes. Trauma was associated with trends in triglyceride levels but not with any other CMR outcomes. DISCUSSION: Experiences with instability distinctly impacted adolescent CMR. Future research is needed to examine factors that can enhance stability for families in marginalized communities.

RESUMO

AIM: Improved identification and treatment of infants at risk of hypoglycaemia using evidence-based guidelines. METHODS: Design: Prospective, multidisciplinary quality improvement project (QIP). SETTING: Tertiary maternity hospital, Dublin (2016-2023). SUBJECTS: Infants at risk for neonatal hypoglycaemia. INTERVENTION: Plan-Do-Study-Act methodology. A hospital-wide survey and ongoing audit informed our initiatives including staff education, antenatal maternal education and standardisation of equipment. Our guidelines were continually evaluated and updated based on emerging evidence. MAIN OUTCOME MEASURES: Neonatal unit (NNU) admissions, adherence to guidelines and use of glucose gel. RESULTS: NNU admissions decreased by 70%, from 3% (118/3883) to 0.9% (34/3806 infants). The number requiring an IV glucose bolus reduced from 25% (29/118) to 6% (2/34). Improved antenatal education, antenatal expression of colostrum and early and frequent feeding also contributed to a reduction in glucose gel use of 94% (1009 tubes in 2018-v-62 in 2022). There were no adverse side effects related to hypoglycaemia. CONCLUSION: Our QIP resulted in a significant reduction in NNU admissions leading to significant cost reductions and NNU workload. More importantly, this resulted in less maternal-infant separation and potentially less parental anxiety and a more supportive environment for breastfeeding. These low-cost initiatives can be implemented in other tertiary maternity hospitals to improve maternity and newborn care.

RESUMO

The study set out to perform a systematic literature review of evidence-based interventions that target the reduction of secondary stroke risk in Africa. The review analyzed longitudinal intervention studies conducted in Sub-Saharan Africa, focusing on adult participants who had suffered a prior stroke. It encompassed publications and peer-reviewed papers sourced from reputable databases, including PubMed, Ovid, Cochrane, and Web of Science. Three randomized clinical trial (RCT) studies were included with sample sizes ranging from 16 to 400 participants, mean age ranged between 50 and 66 years, with 64.5% male participants. All studies applied multidisciplinary team interventions of enhanced patient follow-up involving care givers, nurse educators, physicians, and social workers. Interventions ranged from comprehensive patient education, tracking of medication adherence and enforcing healthy lifestyle behaviors (regular exercise, regular BP checks, and dietary changes). We found a decrease in Systolic Blood Pressure over time in 2 of 3 treatment groups, an improvement in medical adherence in all treatment groups, and a decrease in cholesterol levels in 1 treatment group. Evidence-based interventions involving multidisciplinary teams and comprehensive patient education were found to demonstrate promising results in reducing secondary stroke risk in Africa, leading to significant improvements in medical adherence and reductions in systolic blood pressure in the majority of treatment groups. However, more research is required to confirm the influence of these interventions on cholesterol levels and to establish their lasting advantages in preventing strokes among African communities.

RESUMO

Background: Greater blood pressure variability has detrimental effects on clinical outcome after a stroke; its effects are controversial and have not been evaluated in Sub-Saharan Africa (SSA). Methods: We conducted a prospective study of patients with CT head confirmed ischemic and hemorrhagic strokes admitted to a tertiary hospital within 7 days of onset of unilateral neurological deficits. Blood pressure variability indices, standard deviation (SD) and coefficient of variation (CV) of systolic and diastolic blood pressure between day 0 and day 7, were calculated with a subsequent modified Rankin Scale (mRS) score on day 14 post-stroke. Linear regression was performed to determine the exponential coefficients of mortality at 14 days post- stroke. Results: Out of 120 patients, 51.7% were female, 52.5% had ischemic stroke and the overall median age was 65 (IQR 54-80) years. Twenty (16.7%) patients died within a median survival time of 7 days, while 32 (26.7%) died by day 14 post-stroke. Patients with hemorrhagic stroke had an overall SDSBP of 16.44 mmHg while those with ischemic stroke had an overall SDSBP of 14.05 mmHg. In patients with ischemic stroke, SDSBP had adjusted coefficients of 1, p = 0.004 with C·I: 1.01-1.04 and NIHSS had adjusted coefficients of 1, p = 0.019 with C·I: 1.00-1.03 while in patients with hemorrhagic stroke, SDSBP had adjusted coefficients of 1, p = 0.045 with C·I: 1.00-1.04 and NIHSS had adjusted coefficients of 1, p ≤0.001 with C·I: 1.01-1.03. Conclusion: Exponential increase in Blood Pressure Variability (BPV) and stroke severity scale were independently associated with early mortality among all stroke patients in our study. We recommend future studies to evaluate whether controlling BPV among patients with stroke in Sub-Saharan Africa can reduce mortality.

RESUMO

Stroke outcomes among young adults in Uganda are unclear. This study therefore determined the clinical characteristics and 30-day outcome among young adults with an acute stroke. In a prospective observational cohort study, 61 young adults with confirmed stroke were followed up for 30 days. Socio-demographic and clinical characteristics were collected using a study questionnaire. Kaplan-Meier curves, and modified Poisson regression were performed for factors associated with the 30-day mortality outcome. A third of the screened stroke survivors, (61/195) were young adults aged between 18 and 50 years. About two-thirds were male. More than half were diagnosed with ischaemic strokes while 42.6% had a haemorrhagic stroke. Nearly half (29/61) were known hypertensives, 43% (26/61) had a history of alcohol consumption with 95% classified as dependent on CAGE assessment. Ten percent had a prior smoking history while 29% of the female gender had a prior history of oral contraception use. Twenty-three percent (14/61) of the young stroke patients died within 30 days of stroke onset (95% CI: 0.01, 0. 901). A history of smoking (adjusted prevalence ratio: aPR;5. 094, 95% CI: 3.712, 6. 990) and stroke severity National Institutes of Health Stroke score (NIHSS) >16; Prevalence ratio (PR) -3. 301, 95%CI: 1. 395, 7. 808) and not drinking alcohol (aPR (adjusted prevalence ratio) -7. 247, 95% CI: 4. 491, 11.696) were associated with 30- day mortality. A third of all stroke survivors were young adults. About 23. 3% died within 30 days of stroke onset. Stroke severity and a history of smoking were associated with mortality. Identifying high risk patients and early outpatient follow up may help reduce the 30-day mortality in our settings.

RESUMO

Although research has largely focused on the effects of physical activity (PA) on the brain, less is known about the influence of the brain on engagement in healthy-living behaviors, such as regular PA. In this secondary analysis of a study of brain activity and participation in healthy-living behaviors, we examined relationships between the activation of selected brain networks and PA in persons self-managing chronic conditions. Fifty-eight individuals with chronic conditions underwent functional magnetic resonance imaging while exposed to a protocol consisting of listening to emotion-focused and analytic-focused information and measures of activation of three neuromarkers were obtained: default mode network (DMN), task-positive network (TPN), and ventromedial prefrontal cortex (vmPFC). In an exploratory analysis, we assessed differences in neuromarker activation between two PA levels (representing higher and lower accelerometry-measured PA levels) of 1) moderate-to-vigorous physical activity (MVPA) minutes, 2) metabolic equivalents expended (METs), and 3) daily steps. Results showed positive associations between MVPA and DMN (r = 0.31, P = 0.018), steps and DMN (r = 0.28, P = 0.035), and MVPA and vmPFC (r = 0.29, P = 0.026). No associations were found between the TPN and any of the PA measures. Individuals with high MVPA and METs had higher DMN values compared with those with low MVPA (t = -2.17, P = 0.035) and METs (t = -2.02, P = 0.048). No differences in TPN and vmPFC were found among PA levels. These results suggest that providing health information that activates the emotion-focused brain network may be more useful than analytic-focused information (centered on logic and reasoning) to assist people with chronic conditions to engage in more PA.NEW & NOTEWORTHY The influence of the brain on engagement in regular physical activity (PA) has not been well studied. We examined relationships between the activation of three neuromarkers and two PA levels in 58 persons self-managing chronic conditions. Findings suggest that individuals who optimally process health-information when the emotional tone is high (Empathic Network; DMN) may engage in more PA compared with individuals who respond to health information when the emotional tone is low (Analytic Network; TPN).

RESUMO

The purpose of this article is to propose that knowledge, understanding, and application of systems and complexity thinking can improve assessment, implementation, and evaluation of interprofessional education (IPE). Using a case story, the authors describe and explain a meta-model of systems and complexity thinking to support leaders in implementing and evaluating IPE initiatives. The meta-model incorporates the use of several important, interrelated frameworks that tackle issues of sense making, systems, and complexity thinking as well as polarity management at different levels of scale in an organization. Combined, these theories and frameworks support recognition and management of cross-scale interactions and help leaders make sense of distinctions among simple, complicated, complex, and chaotic situations among IPE issues associated with healthcare disciplines within institutions. The application and use of Liberating Structures and polarity management practices enable leaders to engage people and gain insight into the complexities involved in successful implementation of IPE programs.

RESUMO

Rates of overweight and obesity are problematic among systematically marginalized youth; however, these youth and their families are a hard-to-reach research population. The purpose of our study was to identify facilitators and barriers for recruiting systematically marginalized families in youth weight-management intervention research. This study built upon existing evidence through involvement of youth, parents, community agency workers, and school nurses, and an exploration of both recruitment materials and processes. Seven focus groups were conducted with 48 participants from 4 stakeholder groups (youth, parents, school nurses, and community agency workers). A codebook approach to thematic analysis was used to identify key facilitator and barrier themes related to recruitment materials and processes across the stakeholder groups. Ecological systems theory was applied to contextualize the facilitators and barriers identified. Participants reported the need to actively recruit youth in the study through engaging, fun recruitment materials and processes. Participants reported greater interest in recruitment at community-based events, as compared to recruitment through health care providers, underscoring the depth of distrust that this sample group has for the health care system. Recommendations for recruitment materials and processes for weight-management intervention research with systematically marginalized families are proposed.

RESUMO

OBJECTIVES: In three chronic illness populations and in a combined sample, we assessed differences in two algorithms to determine wear time (WT%) and four algorithms to determine: Kilocalories, light physical activity (PA), moderate-to-vigorous PA (MVPA), and metabolic equivalents (METs). METHODS: Data were collected from 29 people living with HIV (PLHIV), 27 participants recovering from a cardiac event, and 15 participants with hypertension (HTN). Participants wore the ActiGraphTM wGT3X-BT for > 3 days on their hip. Analysis of variance (ANOVA) was used to assess differences among the algorithms. RESULTS: No differences were found between the two algorithms to assess WT% or among the four algorithms to assess kilocalories in each of the chronic illness populations or in the combined sample. Significant differences were found among the four algorithms for light PA (p < .001) and METs (p < .001) in each chronic illness population and in the combined sample. MVPA was significantly different among the four algorithms in the PLHIV (p = .007) and in the combined sample (p < .001), but not in the cardiac (p = .064) or HTN samples (p = .200). DISCUSSION: Our findings indicate that the choice of algorithm does make a difference in PA determination. Differences in algorithms should be considered when comparing PA across different chronic illness populations.

RESUMO

OBJECTIVE: In adult patients with acute respiratory failure, nasal high-flow (NHF) therapy at the time of intubation can decrease the duration of hypoxia. The objective of this pilot study was to calculate duration of peripheral oxygen saturation below 75% during single and multiple intubation attempts in order to inform development of a larger definitive trial. DESIGN AND SETTING: This double-blinded randomised controlled pilot trial was conducted at a single, tertiary neonatal centre from October 2020 to October 2021. PARTICIPANTS: Infants undergoing oral intubation in neonatal intensive care were included. Infants with upper airway anomalies were excluded. INTERVENTIONS: Infants were randomly assigned (1:1) to have NHF 6 L/min, FiO2 1.0 or NHF 0 L/min (control) applied during intubation, stratified by gestational age (<34 weeks vs ≥34 weeks). MAIN OUTCOME MEASURES: The primary outcome was duration of hypoxaemia of <75% up to the time of successful intubation, RESULTS: 43 infants were enrolled (26 <34 weeks and 17 ≥34 weeks) with 50 intubation episodes. In infants <34 weeks' gestation, median duration of SpO2 of <75% was 29 s (0-126 s) vs 43 s (0-132 s) (p=0.78, intervention vs control). Median duration of SpO2 of <75% in babies ≥34 weeks' gestation was 0 (0-32 s) vs 0 (0-20 s) (p=0.9, intervention vs control). CONCLUSION: This pilot study showed that it is feasible to provide NHF during intubation attempts. No significant differences were noted in duration of oxygen saturation of <75% between groups; however, this trial was not powered to detect a difference. A larger, higher-powered blinded study is warranted.

RESUMO

The purpose of this study was to identify facilitators and barriers for engaging youth and families from a historically and systematically marginalized community in high-tech research. Adapting community-based participatory research principles, 4 focus groups were conducted with 13 youth and 12 parents. Using codebook thematic analysis, 5 facilitator themes (develop skills, ensure health, build understanding, promote safety, and help others, youth-initiated interest) and 4 barrier themes (anxiety and fear, skepticism, confusion, and unfamiliar/unknown experience) were identified. Youth and parent responses informed proposed guidelines for recruiting and engaging families in research using high-tech methods, particularly those from historically and systematically marginalized communities.

RESUMO

A propagation pattern for the moment representation of the regularized lattice Boltzmann method (LBM) in three dimensions is presented. Using effectively lossless compression, the simulation state is stored as a set of moments of the lattice Boltzmann distribution function, instead of the distribution function itself. An efficient cache-aware propagation pattern for this moment representation has the effect of substantially reducing both the storage and memory bandwidth required for LBM simulations. This paper extends recent work with the moment representation by expanding the performance analysis on central processing unit (CPU) architectures, considering how boundary conditions are implemented, and demonstrating the effectiveness of the moment representation on a graphics processing unit (GPU) architecture.

RESUMO

BACKGROUND: Uncontrolled blood pressure (BP) rates are persistently high among African Americans with hypertension. Although self-management is critical to controlling BP, little is known about the brain-behavior connections underlying the processing of health information and the performance of self-management activities. OBJECTIVES: In this pilot study, we explored the associations among neural processing of two types of health information and a set of self-management cognitive processes (self-efficacy, activation, decision-making, and hypertension knowledge) and behaviors (physical activity, dietary intake, and medication taking) and health status indicators (BP, health-related quality of life, anxiety, and depression). METHODS: Using a descriptive cross-sectional design, 16 African Americans with uncontrolled hypertension (mean age = 57.5 years, 68.8% women) underwent functional magnetic resonance imaging to assess activation of two neural networks, the task-positive network and the default mode network, and a region in the ventromedial prefrontal cortex associated with emotion-focused and analytic-focused health information. Participants completed self-reports and clinical assessments of self-management processes, behaviors, and health status indicators. RESULTS: Our hypothesis that neural processing associated with different types of health information would correlate with self-management cognitive processes and behaviors and health status indicators was only partially supported. Home diastolic BP was positively associated with ventromedial prefrontal cortex activation ( r = .536, p = .09); no other associations were found among the neural markers and self-management or health status variables. Expected relationships were found among the self-management processes and behaviors and health status indicators. DISCUSSION: To advance our understanding of the neural processes underlying health information processing and chronic illness self-management, future studies are needed that use larger samples with more heterogeneous populations and additional neuroimaging techniques.

RESUMO

BACKGROUND: For the 720 000 Americans expected to experience a new acute cardiac event this year, cardiac rehabilitation is an important part of recovery. Symptoms of depression and anxiety undermine recovery efforts, leaving recovering patients at risk for diminished functional capacity and heightened risk of mortality. Poor emotion regulation can worsen symptoms of depression and anxiety and hinder recovery efforts. OBJECTIVE: The purpose of this randomized controlled trial was to evaluate the early efficacy testing of a theoretically based emotion regulation treatment (Regulating Emotions to Improve Self-management of Nutrition, Exercise, and Stress [RENEwS]) designed to assist survivors of an acute cardiac event in cardiac rehabilitation to optimize recovery. METHODS: Survivors of an acute cardiac event in cardiac rehabilitation (n = 30, 83% men) were randomized to five 1-hour in-person group sessions of RENEwS or a phone-based attention-control group. Participants completed measures of depression and anxiety symptoms at 3 time points. Moderate to vigorous physical activity (MVPA) was objectively measured for 7 days at each time point using waist-worn actigraphy monitors. Between-group differences were calculated using analysis of variance with Cohen f effect sizes calculated to evaluate initial efficacy. RESULTS: There was no statistically significant difference in depression, anxiety, or MVPA over time based on group assignment (all P > .05). Compared with attention control participants, in RENEwS participants, preliminary effects showed greater reductions in depression (Cohen f = 0.34) and anxiety (Cohen f = 0.40) symptoms but only modest improvements in MVPA from baseline to 5 months (Cohen f = 0.08). CONCLUSIONS: Findings show that RENEwS is a promising emotion regulation intervention to enhance cardiac rehabilitation and potentially decrease symptoms of depression and anxiety.

RESUMO

The ability to track simulated cancer cells through the circulatory system, important for developing a mechanistic understanding of metastatic spread, pushes the limits of today's supercomputers by requiring the simulation of large fluid volumes at cellular-scale resolution. To overcome this challenge, we introduce a new adaptive physics refinement (APR) method that captures cellular-scale interaction across large domains and leverages a hybrid CPU-GPU approach to maximize performance. Through algorithmic advances that integrate multi-physics and multi-resolution models, we establish a finely resolved window with explicitly modeled cells coupled to a coarsely resolved bulk fluid domain. In this work we present multiple validations of the APR framework by comparing against fully resolved fluid-structure interaction methods and employ techniques, such as latency hiding and maximizing memory bandwidth, to effectively utilize heterogeneous node architectures. Collectively, these computational developments and performance optimizations provide a robust and scalable framework to enable system-level simulations of cancer cell transport.

RESUMO

Behavioral interventions consolidating technology are underutilized and do not reach diverse populations such as African Americans with hypertension. This pilot study aimed to evaluate the effects of a theoretically derived, technology-based intervention in African Americans with hypertension. African Americans with hypertension (N = 18; age range 25-85; 72.22% females) were randomized to the technology-based plus positive psychological training (PPT) experimental group (n = 10) or the comparison group (n = 8) for 12 weeks. The technology-based intervention included analytic components (web-based education, self-monitoring of blood pressure [BP], and medication management using a commercially free app-Medisafe) and an emotional component (comprised of skills and behaviors directed at engaging 1 in positive activities to help build increasing healthy behaviors). The comparison group received the technology-based intervention alone. Demographic information, self-management cognitive processes, self-management behaviors, and health status outcomes were assessed. After completing the 12-week intervention, the groups did not significantly differ in health outcomes, health behavior outcomes, and technology utilization outcomes. Mean systolic BP decrease 6.02 mmHg (standard deviation [SD] = 22.75) in the comparison group and 1.1 mmHg (SD = 20.64; P = .439) in the experimental group. Diastolic BP decreased 0.1 mmHg (SD = 11.78) in the comparison group and 1.5 mmHg (SD = 12.7; P = .757) in the experimental group. Our findings suggest that behavioral interventions using technology have the potential to improve self-management outcomes among African American populations. Further research is warranted in a larger sample size and a longer time frame to identify the intervention's effectiveness.

RESUMO

INTRODUCTION: Stroke burden is rapidly increasing globally. Modifiable risk factors offer an opportunity to intervene, and targeting hypertension is a key actionable target for stroke risk reduction in sub-Saharan Africa. This 3-site planned randomized controlled trial builds on promising preliminary data. METHODS: A total of 246 Ugandan adults will be recruited randomized to experimental intervention vs. enhanced treatment control. Intervention participants will receive six weekly group-format stroke risk reduction self-management training sessions, and the controls will receive information on cardiovascular risk.
