RESUMO

BACKGROUND: Approaches to prevent and manage diabetes at a community population level are hindered because current strategies are not aligned with the structure and function of a community system. We describe a community-driven process based on local data and rapid prototyping as an alternative approach to create diabetes prevention and care management solutions appropriate for each community. We report on the process and provide baseline data for a 3-year case study initiative to improve diabetes outcomes in two rural Nebraska communities. METHODS: We developed an iterative design process based on the assumption that decentralized decision-making using local data feedback and monitoring will lead to the innovation of local sustainable solutions. Coalitions act as community innovation hubs and meet monthly to work through a facilitated design process. Six core diabetes measures will be tracked over the course of the project using the electronic health record from community clinics as a proxy for the entire community. RESULTS: Baseline data indicate two-thirds of the population in both communities are at risk for prediabetes based on age and body mass index. However, only a fraction (35% and 12%) of those at risk have been screened. This information led both coalitions to focus on improving screening rates in their communities. DISCUSSION: In order to move a complex system towards an optimal state (e.g., improved diabetes outcomes), stakeholders must have access to continuous feedback of accurate, pertinent information in order to make informed decisions. Conventional approaches of implementing evidence-based interventions do not facilitate this process.

RESUMO

BACKGROUND: The club cell secretory protein (CC16) has anti-inflammatory and antioxidant effects, and low CC16 serum levels have been associated with both risk and progression of COPD, yet the interaction between smoking and CC16 on lung function outcomes remains unknown. METHODS: Utilizing cross-sectional data on United States veterans, CC16 serum concentrations were measured by ELISA and log transformed for analyses. Spirometry was conducted and COPD status was defined by post-bronchodilator FEV1/FVC ratio < 0.7. Smoking measures were self-reported on questionnaire. Multivariable logistic and linear regression were employed to examine associations between CC16 levels and COPD, and lung function with adjustment for covariates. Unadjusted Pearson correlations described relationships between CC16 level and lung function measures, pack-years smoked, and years since smoking cessation. RESULTS: The study population (N = 351) was mostly male, white, with an average age over 60 years. An interaction between CC16 and smoking status on FEV1/FVC ratio was demonstrated among subjects with COPD (N = 245, p = 0.01). There was a positive correlation among former smokers and negative correlation among current or never smokers with COPD. Among former smokers with COPD, CC16 levels were also positively correlated with years since smoking cessation, and inversely related with pack-years smoked. Increasing CC16 levels were associated with lower odds of COPD (ORadj = 0.36, 95% CI 0.22-0.57, Padj < 0.0001). CONCLUSIONS: Smoking status is an important effect modifier of CC16 relationships with lung function. Increasing serum CC16 corresponded to increases in FEV1/FVC ratio in former smokers with COPD versus opposite relationships in current or never smokers. Additional longitudinal studies may be warranted to assess relationship of CC16 with smoking cessation on lung function among subjects with COPD.

RESUMO

Background: We used the Therapy Preference Scale, a 30-item questionnaire, to determine cancer treatment preferences of adults with cancer. Methods: We used Wilcoxon's rank sum test and Fisher's exact test to compare the preferences of younger (<60 years) versus older adults (≥60 years). Results: While 56% of patients would accept treatment offering increased life expectancy at an expense of short-term side effects, 75% preferred maintenance of cognition, functional ability and quality of life to quantity of days. Oral instead of intravenous treatment (p = 0.003), shorter hospital stay (p = 0.03), preservation of cognitive function (p = 0.01) and avoidance of pain (p = 0.02) were more important to older patients compared with younger patients. Conclusion: Many patients prioritized maintenance of cognition, functional ability and quality of life; older patients valued oral treatment, shorter hospital stay, preservation of cognitive function and avoidance of pain.


Lay abstract Understanding the preferences of adults with cancer is important for physicians to develop personalized cancer treatment plans. We used a self-reported 30-item questionnaire, the Therapy Preference Scale, to help patients express their preferences with regard to safety, efficacy and other aspects of therapy. While 56% of the patients in our study would accept treatment offering increased life expectancy at an expense of short-term side effects, 75% preferred maintenance of cognition, functional ability and quality of life to quantity of days. Compared with younger patients, older patients preferred oral instead of intravenous treatment, shorter hospital stay, preservation of cognitive function and avoidance of pain.

RESUMO

BACKGROUND: Aortic elasticity creates a cushion that protects the heart from pressure injury, and a recoil that helps perfuse the coronary arteries. TEVAR has become first-line therapy for many aortic pathologies including trauma, but stent-grafts stiffen the aorta and likely increase LV afterload. OBJECTIVE: Test the hypothesis that trauma TEVAR is associated with LV mass increase and adverse off-target aortic remodeling. METHODS: Computed Tomography Angiography (CTA) scans of 20 trauma TEVAR patients (17 M/3 F) at baseline [age 34.9 ±â€Š18.5 (11.4-71.5) years] and 5.1 ±â€Š3.1 (1.1-12.3) years after repair were used to measure changes in LV mass, LV mass index, and diameters and lengths of the ascending thoracic aorta (ATA). Measurements were compared with similarly-aged control patients without aortic repair (21 M/21 F) evaluated at similar follow-ups. RESULTS: LV mass and LV mass index of TEVAR patients increased from 138.5 ±â€Š39.6 g and 72.35 ±â€Š15.17 g/m2 to 173.5 ±â€Š50.1 g and 85.48 ±â€Š18.34 g/m2 at the rate of 10.03 ±â€Š12.79 g/yr and 6.25 ±â€Š10.28 g/m2/yr, whereas in control patients LV characteristics did not change. ATA diameters of TEVAR patients increased at a rate of 0.60 ±â€Š0.80 mm/yr, which was 2.4-fold faster than in controls. ATA length in both TEVAR and control patients increased at 0.58 mm/yr. Half of TEVAR patients had hypertension at follow-up compared to only 5% at baseline. CONCLUSIONS: TEVAR is associated with LV mass increase, development of hypertension, and accelerated expansile remodeling of the ascending aorta. Although younger trauma patients may adapt to these effects, these changes may be even more important in older patients with other aortic pathologies and diminished baseline cardiac function.

RESUMO

We incorporated questions related to safety, effectiveness and other characteristics of systemic cancer treatment into a self-report questionnaire - the Therapy Preference Scale - that captures patients´ preferences. The authors asked 20 experts to assess content validity and an additional 20 experts, patients and community members to examine face validity and guide revisions. Key revisions included shortening the length, clarifying constructs and providing details to explain the context and trade-offs necessary to balance the risks and benefits of cancer treatment. The content validity index for the final questionnaire was 1.0, indicating that all questions were relevant. Reviewers expressed that the questionnaire would serve an important purpose. Experts, patients and community members guided revisions of the questionnaire and documented its value.

RESUMO

OBJECTIVE: Comparative analyses of survival and funding statistics in cancers with high mortality were performed to quantify discrepancies and identify areas for intervention. BACKGROUND: Discrepancies in research funding may contribute to stagnant survival rates in pancreatic ductal adenocarcinoma (PDAC). METHODS: The Surveillance, Epidemiology, and End Results database was queried for survival statistics. Funding data were obtained from the National Cancer Institute (NCI). Clinical trial data were obtained from www.clinicaltrials.gov. Cancers with high mortality were included for analyses. RESULTS: Since 1997, PDAC has received lesser funding ($1.41 billion) than other cancers such as breast ($10.52 billion), prostate ($4.93 billion), lung ($4.80 billion), and colorectal ($4.50 billion). Similarly, fewer clinical trials have been completed in PDAC (n = 608) compared with breast (n = 1904), lung (n = 1629), colorectal (n = 1080), and prostate (n = 1055) cancer. Despite this, since 1997, dollars invested in PDAC research produced a greater return on investment with regards to 5-year overall survival (5Y-OS) compared with breast, prostate, uterine, and ovarian cancer. Incremental cost-effectiveness analysis demonstrates that millions (liver, non-Hodgkin lymphoma, and melanoma) and billions (colorectal and lung) of dollars were required for each additional 1% increase in 5Y-OS compared with PDAC. Funding of research towards early diagnosis of PDAC has decreased by 19% since 2007. For nearly all cancers, treatment-related research receives the highest percentage of NCI funding. CONCLUSIONS: Funding of PDAC research is significantly less than other cancers, despite its higher mortality and greater potential to improve 5Y-OS. Increased awareness and lobbying are required to increase funding, promote research, and improve survival.

RESUMO

PURPOSE: This study investigates the clinical and cost effectiveness of switching from traditional vagus nerve stimulation (VNS) to responsive VNS (rVNS), which has an additional ictal tachycardia detection and stimulation (AutoStim) mode. METHODS: Retrospective chart review was used to collect data from patients with medically refractory epilepsy who underwent generator replacements. Patients with confounding factors such as medication changes were excluded. Vagus nerve stimulation parameters, seizure frequency, and healthcare costs were collected for the 1-year period following generator replacement with the rVNS device. RESULTS: Documented seizure frequency was available for twenty-five patients. After implant with rVNS, 28% of patients had an additional ≥50% seizure reduction. There was a significant decrease in the average monthly seizure count (p = 0.039). In patients who were not already free of disabling seizures (n = 17), 41.2% had ≥50% additional seizure reduction. There was no difference in healthcare costs during the 1-year follow-up after the rVNS implant compared with one year prior. CONCLUSIONS: Ictal tachycardia detection and stimulation provided a significant clinical benefit in patients who were not free of disabling seizures with treatment from traditional VNS. There was no additional increase in healthcare costs during the first year after device replacement.

RESUMO

BACKGROUND AND OBJECTIVES: Cardiac surgical interventions for children with trisomy 18 and trisomy 13 remain controversial, despite growing evidence that definitive cardiac repair prolongs survival. Understanding quality of life for survivors and their families therefore becomes crucial. Study objective was to generate a descriptive summary of parental perspectives on quality of life, family impact, functional status, and hopes for children with trisomy 18 and trisomy 13 who have undergone heart surgery. METHODS: A concurrent mixed method approach utilising PedsQL™ 4.0 Generic Core Parent Report for Toddlers or the PedsQL™ Infant Scale, PedsQL™ 2.0 Family Impact Module, Functional Status Scale, quality of life visual analogue scale, and narrative responses for 10 children whose families travelled out of state to access cardiac surgery denied to them in their home state due to genetic diagnoses. RESULTS: Parents rated their child's quality of life as 80/100, and their own quality of life as 78/100 using validated scales. Functional status was rated 11 by parents and 11.6 by providers (correlation 0.89). On quality of life visual analogue scale, all parents rated their child's quality of life as "high" with mean response 92.7/100. Parental hopes were informed by realistic perspective on prognosis while striving to ensure their children had access to reaching their full potential. Qualitative analysis revealed a profound sense of the child's relationality and valued life meaning. CONCLUSION: Understanding parental motivations and perceptions on the child's quality of life has potential to inform care teams in considering cardiac interventions for children with trisomy 18 and trisomy 13.

RESUMO

OBJECTIVE: The role of aromatherapy in supportive symptom management for pediatric patients receiving palliative care has been underexplored. This pilot study aimed to measure the impact of aromatherapy using validated child-reported nausea, pain, and mood scales 5 minutes and 60 minutes after aromatherapy exposure. METHODS: The 3 intervention arms included use of a symptom-specific aromatherapy sachet scent involving deep breathing. The parallel default control arm (for those children with medical exclusion criteria to aromatherapy) included use of a visual imagery picture envelope and deep breathing. Symptom burden was sequentially assessed at 5 and 60 minutes using the Baxter Retching Faces scale for nausea, the Wong-Baker FACES scale for pain, and the Children's Anxiety and Pain Scale (CAPS) for anxious mood. Ninety children or adolescents (mean age 9.4 years) at a free-standing children's hospital in the United States were included in each arm (total n = 180). RESULTS: At 5 minutes, there was a mean improvement of 3/10 (standard deviation [SD] 2.21) on the nausea scale; 2.6/10 (SD 1.83) on the pain scale; and 1.6/5 (SD 0.93) on the mood scale for the aromatherapy cohort (p < 0.0001). Symptom burden remained improved at 60 minutes post-intervention (<0.0001). Visual imagery with deep breathing improved self-reports of symptoms but was not as consistently sustained at 60 minutes. SIGNIFICANCE OF RESULTS: Aromatherapy represents an implementable supportive care intervention for pediatric patients receiving palliative care consults for symptom burden. The high number of children disqualified from the aromatherapy arm because of pulmonary or allergy indications warrants further attention to outcomes for additional breathing-based integrative modalities.

RESUMO

School engagement protects against negative mental health outcomes; however, few studies examined the relationship between school engagement and attention-deficit hyperactivity disorder (ADHD) using an ecological framework. The aims were to examine: (1) whether school engagement has an independent protective association against the risk of ADHD in children, and (2) whether environmental factors have an association with ADHD either directly or indirectly via their association with school engagement. This cross-sectional study used data from the 2011-2012 National Survey of Children's Health, which collected information about children's mental health, family life, school, and community. The sample contained 65,680 children aged 6-17 years. Structural equation modeling was used to estimate the direct association of school engagement and ADHD and indirect associations of latent environmental variables (e.g., family socioeconomic status (SES), adverse childhood experiences (ACEs), environmental safety, and neighborhood amenities) and ADHD. School engagement had a direct and inverse relationship with ADHD (ß = - 0.35, p < 0.001) such that an increase in school engagement corresponds with a decrease in ADHD diagnosis. In addition, family SES (ß = - 0.03, p = 0.002), ACEs (ß = 0.10, p < 0.001), environment safety (ß = - 0.10, p < 0.001), and neighborhood amenities (ß = - 0.01, p = 0.025) all had an indirect association with ADHD via school engagement. In conclusion, school engagement had a direct association with ADHD. Furthermore, environmental correlates showed indirect associations with ADHD via school engagement. School programs targeted at reducing ADHD should consider family and community factors in their interventions.

RESUMO

Injurious dust exposures in the agricultural workplace involve the release of inflammatory mediators and activation of epidermal growth factor receptor (EGFR) in the respiratory epithelium. Amphiregulin (AREG), an EGFR ligand, mediates tissue repair and wound healing in the lung epithelium. Omega-3 fatty acids such as docosahexaenoic acid (DHA) are also known modulators of repair and resolution of inflammatory injury. This study investigated how AREG, DHA, and EGFR modulate lung repair processes following dust-induced injury. Primary human bronchial epithelial (BEC) and BEAS-2B cells were treated with an aqueous extract of swine confinement facility dust (DE) in the presence of DHA and AREG or EGFR inhibitors. Mice were exposed to DE intranasally with or without EGFR inhibition and DHA. Using a decellularized lung scaffolding tissue repair model, BEC recolonization of human lung scaffolds was analyzed in the context of DE, DHA, and AREG treatments. Through these investigations, we identified an important role for AREG in mediating BEC repair processes. DE-induced AREG release from BEC, and DHA treatment following DE exposure, enhanced this release. Both DHA and AREG also enhanced BEC repair capacities and rescued DE-induced recellularization deficits. In vivo, DHA treatment enhanced AREG production following DE exposure, whereas EGFR inhibitor-treated mice exhibited reduced AREG in their lung homogenates. These data indicate a role for AREG in the process of tissue repair after inflammatory lung injury caused by environmental dust exposure and implicate a role for DHA in regulating AREG-mediated repair signaling in BEC.

RESUMO

Glaucoma represents a group of multifactorial diseases with a unifying pathology of progressive retinal ganglion cell (RGC) degeneration, causing irreversible vision loss. To test the hypothesis that RGCs are intrinsically vulnerable in glaucoma, we have developed an in vitro model using the SIX6 risk allele carrying glaucoma patient-specific induced pluripotent stem cells (iPSCs) for generating functional RGCs. Here, we demonstrate that the efficiency of RGC generation by SIX6 risk allele iPSCs is significantly lower than iPSCs-derived from healthy, age- and sex-matched controls. The decrease in the number of RGC generation is accompanied by repressed developmental expression of RGC regulatory genes. The SIX6 risk allele RGCs display short and simple neurites, reduced expression of guidance molecules, and immature electrophysiological signature. In addition, these cells have higher expression of glaucoma-associated genes, CDKN2A and CDKN2B, suggesting an early onset of the disease phenotype. Consistent with the developmental abnormalities, the SIX6 risk allele RGCs display global dysregulation of genes which map on developmentally relevant biological processes for RGC differentiation and signaling pathways such as mammalian target of rapamycin that integrate diverse functions for differentiation, metabolism, and survival. The results suggest that SIX6 influences different stages of RGC differentiation and their survival; therefore, alteration in SIX6 function due to the risk allele may lead to cellular and molecular abnormalities. These abnormalities, if carried into adulthood, may make RGCs vulnerable in glaucoma. Stem Cells 2017;35:2239-2252.

RESUMO

BACKGROUND: The role of B-type natriuretic peptide (BNP) is less understood in the risk stratification of patients with an acute exacerbation of chronic obstructive pulmonary disease (AECOPD), especially in patients with normal left ventricular ejection fraction (LVEF). METHODS: This retrospective study from 2008 to 2012 evaluated all adult patients with AECOPD having BNP levels and available echocardiographic data demonstrating LVEF ≥40%. The patients were divided into groups 1, 2, and 3 with BNP ≤ 100, 101 to 500, and ≥501 pg/mL, respectively. A subgroup analysis was performed for patients without renal dysfunction. Outcomes included need for and duration of noninvasive ventilation (NIV) and mechanical ventilation (MV), NIV failure, reintubation at 48 hours, intensive care unit (ICU) and total length of stay (LOS), and in-hospital mortality. Two-tailed P < .05 was considered statistically significant. RESULTS: Of the total 1145 patients, 550 (48.0%) met our inclusion criteria (age 65.1 ± 12.2 years; 271 [49.3%] males). Groups 1, 2, and 3 had 214, 216, and 120 patients each, respectively, with higher comorbidities and worse biventricular function in higher categories. Higher BNP values were associated with higher MV use, NIV failure, MV duration, and ICU and total LOS. On multivariate analysis, BNP was an independent predictor of higher NIV and MV use, NIV failure, NIV and MV duration, and total LOS in groups 2 and 3 compared to group 1. B-type natriuretic peptide continued to demonstrate positive correlation with NIV and MV duration and ICU and total LOS independent of renal function in a subgroup analysis. CONCLUSION: Elevated admission BNP in patients with AECOPD and normal LVEF is associated with worse in-hospital outcomes and can be used to risk-stratify these patients.

RESUMO

STATEMENT OF PROBLEM: To our knowledge, no data are available on the actual lighting that is used for visual shade matching in private dental offices. PURPOSE: The purpose of this study was to determine the shade matching practices and interest in continuing education in dental practices and to determine the quantity and quality of the ambient lighting used during visual shade matching in a sample cohort of dentists in private practices. MATERIAL AND METHODS: Thirty-two private practices were enrolled, and each completed a 1-page survey on the clinic's shade matching practices. A spectrophotometer was used to measure the ambient lighting in each practice, collecting data on color temperature (Kelvin), color rendering index (CRI), and light intensity (foot candles/fc). A 2-sided nonparametric sign test was used to compare the true median color temperature with the standard (5500°K). A 1-sided t test was used to compare the CRI with the standard (CRI >90) (α=.05 for all statistical analyses). RESULTS: All dental practitioners surveyed used mainly visual shade matching in their practices. Of those, 87.5% showed interest in attending continuing education on this topic, with 56.3% preferring a clinical demonstration course. The mean color temperature was 4152.9°K and was significantly different from the standard 5500°K (P<.001). The 1-sided t test indicated that the mean CRI was less than 90 (P=1). The 95% confidence interval for the intensity was 80.7 to 111.6 fc. CONCLUSIONS: The ambient light in the majority of the 32 dental private practices measured was not ideal for visual shade matching.

RESUMO

OBJECTIVE: This study identified rural community experiences and preferences related to available resources and their effects on stress following tornadoes and floods. METHODS: The Rural Natural Disaster Stress and Recovery survey was distributed from December 2021 to February 2022 in rural disaster-affected communities. Within the analysis sample (N = 159) of self-selected participants representing both agricultural and non-agricultural occupations, 125 responded to the Resource Use and Effect survey component that evaluated the effects of 22 resources on post-disaster stress. Additional qualitative questions provided further data. RESULTS: The most frequently used resources post-disaster were found to be talking about the event (98.3%), friends and neighbors (97.6%) and family (97.6%). Using a derived Impact per Use score, groups from the neighboring community and personal faith activities most often reduced stress. Resources that increased stress were identified as FEMA or other government organizations; repairing, replacing, or rebuilding property; and following news or social media. Participants reported help from their community (35.8%) or things they did for themselves (31.2%) most effectively decreased disaster stress. Family, friends, faith, neighbors, and community were top choices to decrease stress in a future disaster. CONCLUSION: Rural residents identified available resources for reducing disaster stress, but some common post-disaster activities were found to increase stress. Rural emergency management should adapt response and recovery plans and activities to leverage readily accessible people, groups, and activities to mitigate negative mental and emotional health effects.

RESUMO

BACKGROUND: Adult-led organized settings for children (eg, classrooms) provide opportunities for physical activity (PA). The structure of setting time may influence inequalities (ie, unequalness) in the distribution of PA. This study examined differences in PA inequality by setting and time-segment purpose in time-segmented organized group settings for children. METHODS: PA and setting meetings were assessed using accelerometer and video observation data from school, before-/after-school, and youth club groups (n = 30) for third- through sixth-grade children (n = 699) in 2 rural US communities. Meetings (n = 130) were time-segmented into smaller units (sessions; n = 835). Each session was assigned a purpose code (eg, PA). Accelerometer data were paired with the meetings and sessions, and the Gini coefficient quantified inequality in activity counts and moderate to vigorous PA minutes for each segment. Beta generalized estimating equations examined differences in PA inequality by setting and session purpose. RESULTS: Activity count inequality was lowest (P < .05) during youth club meetings (Gini = 0.17, 95% CI, 0.14-0.20), and inequality in moderate to vigorous PA minutes was greatest (P < .01) during school (Gini = 0.34, 95% CI, 0.30-0.38). Organized PA sessions (Gini = 0.20, 95% CI, 0.17-0.23) had lower activity count inequality (P < .0001) than academic (Gini = 0.30, 95% CI, 0.27-0.34), enrichment (Gini = 0.31, 95% CI, 0.27-0.36), and nonactive recreation (Gini = 0.30, 95% CI, 0.25-0.34) sessions. Inequality in moderate to vigorous PA minutes was lower (P < .05) in organized PA (Gini = 0.26, 95% CI, 0.20-0.32) and free play (Gini = 0.28, 95% CI, 0.19-0.39) than other sessions. CONCLUSIONS: PA inequality differed by setting time structure, with lower inequality during organized PA sessions. The Gini coefficient can illuminate PA inequalities in organized settings and may inform population PA improvement efforts in rural communities.

RESUMO

Purpose: Youth sport (YS) is a community system for promoting children's physical activity (PA). Studies have examined mean PA during YS practices, but few have examined inequalities in the distribution of PA among children during practice time. This study examined PA inequality in time-segmented YS practices and differences in inequality by time segment characteristics. Methods: Children's PA and YS practices were examined using accelerometer and video observation data from a sample of YS teams (n = 36 teams, n = 101 practices) for third- through sixth-grade children (n = 392), approximately eight to 12 years old, in two rural U.S. communities. Practices were time-segmented into smaller units (episodes; n = 991). Episodes were assigned codes for purpose (e.g. warm-up), member arrangement (e.g. whole group), and setting demand (i.e. fosters participation, creates exclusion). Group accelerometer data were paired with episodes, and the Gini coefficient quantified inequality in activity counts and minutes of moderate-to-vigorous PA (MVPA). Beta generalized estimating equations examined the influence of episode structure on PA inequality. Results: Warm-up (Gini = 0.22), fitness (Gini = 0.24), and sport skill (Gini = 0.24) episodes had significantly lower inequality (p < .05) in activity counts than other purpose types. Management (Gini = 0.32) and strategy (Gini = 0.40) episodes had significantly greater inequality (p < .05) in MVPA minutes than other purpose types. Episodes fostering participation (Gini = 0.32) had significantly lower activity count inequality (p < .05) than episodes creating exclusion (Gini = 0.35). Conclusion: PA inequality among children during YS varied by practice structure. Metrics such as the Gini coefficient can illuminate inequalities in PA and may be useful for guiding efforts to improve population PA in children. Trial Registration: This study is registered at www.clinicaltrials.gov (Identifier: NCT03380143).

RESUMO

Background: This study explores heart failure (HF) dyadic contextual factors and caregiver burden during acute exacerbation hospitalization and discharge. Methods: It employed a mixed-methods approach, with HF dyads completing questionnaires and semi-structured interviews at a one-week post-discharge outpatient visit. Quantitative tools included the SF-12 Quality of Life, Zarit Burden Interview (ZBI), Bakas Caregiving Outcomes Scale (BCOS), and Self-Care of Heart Failure Index v. 6 (SCHFI). Thematic analysis was conducted on interview data to assess caregiver burden, disease trajectory, comorbidities, caregiving time, and employment status. Results: Twelve HF dyads participated, with caregivers (six female, six male) averaging 65.76 years. The ZBI indicated a low caregiver burden (median score of 15), but qualitative data revealed a higher perceived burden related to social isolation, future fears, and caregiver dependence. Male caregivers reported a lower burden than females. Positive goal congruence was noted in caregiving hours and HF management compliance. HF patients had a 10-year survival prediction of 22.75% per the Charlson Comorbidity Index, with 69% in NYHA class III and an average ejection fraction of 37.7%. Caregivers working full-time and caring for higher NYHA-class patients showed higher ZBI and BCOS scores. Conclusions: The study highlights the need for mixed methods and longitudinal research to understand HF disease trajectory and caregiver burden, emphasizing the importance of including caregivers in HF education and screening for perceived burden to improve outcomes and reduce re-hospitalizations.

RESUMO

BACKGROUND: Psychological response is important in return-to-sport decisions for athletes recovering from anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to compare psychological response after ACLR with a concomitant meniscus repair compared to isolated ACLR. METHODS: Thirty-five individuals completed the Tampa Scale of Kinesiophobia (TSK) and Anterior Cruciate Ligament Return-to-Sport after Injury (ACL-RSI) scale before ACLR and 2, 4, and 6 months after ACLR. Participants were dichotomized based on presence of concomitant meniscus repair (Yes/No). Separate group X time repeated measures analyses of variance were conducted for both scales. RESULTS: Participants were 65.7% female, 19.1 ± 4.7 years old with BMI of 24.9 ± 4.4 kg/m2. Sixteen individuals had an isolated ACLR with 19 individuals having an ACLR with concomitant meniscus repair. For the TSK, there was a group × time interaction effect(p = 0.028), with improvement in TSK scores for the isolated ACLR group (ACLR:2 months = 24.8 ± 3.7; 4 months = 22.0 ± 5.7; 6 months: 19.9 ± 5.9; Meniscus Repair:2 months = 25.5 ± 4.7; 4 months = 24.1 ± 5.0; 6 months: 23.8 ± 4.7). Six months after ACLR, TSK scores were worse in the meniscus repair group(p = 0.036). For the ACL-RSI, there was no interaction(p = 0.07). CONCLUSION: Concomitant meniscus repair with ACLR results in less post-operative improvement in kinesiophobia through 6 months after ACLR compared to isolated ACLR.

RESUMO

Background: Spatiotemporal parameters of gait are useful for identifying pathological gait patterns and presence of impairments. Reliability of the pressure-sensitive ZenoTM Walkway has not been established in young, active individuals without impairments, and no studies to this point have included running. Purpose: The purposes of this study were to 1) determine if up to two additional trials of walking and running on the ZenoTM Walkway are needed to produce consistent measurements of spatiotemporal variables, and 2) establish test-retest reliability and minimal detectable change (MDC) values for common spatiotemporal variables measured during walking and running. Study Design: Cross-Sectional Laboratory Study. Methods: Individuals (n=38) in this cross-sectional study walked and ran at self-selected comfortable speed on a pressure-sensitive ZenoTM Walkway. Twenty-one participants returned for follow-up testing between one and 14 days later. Intraclass correlation coefficients (ICCs) were used to assess reliability of spatiotemporal variable means using three, four, or five passes over the ZenoTM Walkway and to assess test-retest reliability of spatiotemporal variables across sessions. Results: All variables showed excellent reliability (ICC > 0.995) for walking and running when measured using three, four, or five passes. Additionally, all variables demonstrated moderate to excellent test-retest reliability during walking (ICC: 0.732-0.982) and running (ICC: 0.679-0.985). Conclusion: This study establishes a reliable measurement protocol of three one-way passes when using the ZenoTM Walkway for walking or running analysis. This is the first study to establish reliability of the ZenoTM Walkway during running and in young, active individuals without neuromusculoskeletal pathology. Level of Evidence: 3b.
