Disentangling sex-dependent effects of APOE on diverse trajectories of cognitive decline in Alzheimer's disease.

Current diagnostic systems for Alzheimer's disease (AD) rely upon clinical signs and symptoms, despite the fact that the multiplicity of clinical symptoms renders various neuropsychological assessments inadequate to reflect the underlying pathophysiological mechanisms. Since putative neuroimaging biomarkers play a crucial role in understanding the etiology of AD, we sought to stratify the diverse relationships between AD biomarkers and cognitive decline in the aging population and uncover risk factors contributing to the diversities in AD. To do so, we capitalized on a large amount of neuroimaging data from the ADNI study to examine the inflection points along the dynamic relationship between cognitive decline trajectories and whole-brain neuroimaging biomarkers, using a state-of-the-art statistical model of change point detection. Our findings indicated that the temporal relationship between AD biomarkers and cognitive decline may differ depending on the synergistic effect of genetic risk and biological sex. Specifically, tauopathy-PET biomarkers exhibit a more dynamic and age-dependent association with Mini-Mental State Examination scores (p<0.05), with inflection points at 72, 78, and 83 years old, compared with amyloid-PET and neurodegeneration (cortical thickness from MRI) biomarkers. In the landscape of health disparities in AD, our analysis indicated that biological sex moderates the rate of cognitive decline associated with APOE4 genotype. Meanwhile, we found that higher education levels may moderate the effect of APOE4, acting as a marker of cognitive reserve.

The Role of Exercise in Management of Mental Health Disorders: An Integrative Review.

A large and growing body of evidence suggests that physical activity (PA) may hold therapeutic promise in the management of mental health disorders. Most evidence linking PA to mental health outcomes has focused on the effects of aerobic exercise training on depression, although a growing body of work supports the efficacy of both aerobic and resistance exercise paradigms in the treatment of anxiety and post-traumatic stress disorder. Despite abundant evidence linking PA and mental health, use of exercise training as a mental health treatment remains limited due to three important sources of uncertainty: (a) large individual differences in response to exercise treatment within multiple mental health domains; (b) the critical importance of sustained PA engagement, not always achieved, for therapeutic benefit; and (c) disagreement regarding the relative importance of putative therapeutic mechanisms. Our review of treatment data on exercise interventions and mental health outcomes focuses primarily on depression and anxiety within a health neuroscience framework. Within this conceptual framework, neurobiological and behavioral mechanisms may have additiveor synergistic influences on key cognitive and behavioral processes that influence mental health outcomes. We therefore highlight sources of treatment heterogeneity by integrating the critical influences of (a) neurobiological mechanisms enhancing neuroplasticity and (b) behavioral learning of self-regulatory skills. Understanding the interrelationships between dynamic neurobiological and behavioral mechanisms may help inform personalized mental health treatments and clarify why, and for whom, exercise improves mental health outcomes. The review concludes with recommendations for future studies leveraging individual differences to refine treatment approaches to optimize mental health benefits.

Multidisciplinary Care in Heart Failure Services.

The American College of Cardiology/American Heart Association/Heart Failure Society of American 2022 guidelines for heart failure (HF) recommend a multidisciplinary team approach for patients with HF. The multidisciplinary HF team-based approach decreases the hospitalization rate for HF and health care costs and improves adherence to self-care and the use of guideline-directed medical therapy. This article proposes the optimal multidisciplinary team structure and each team member's delineated role to achieve institutional goals and metrics for HF care. The proposed HF-specific multidisciplinary team comprises cardiologists, surgeons, advanced practice providers, clinical pharmacists, specialty nurses, dieticians, physical therapists, psychologists, social workers, immunologists, and palliative care clinicians. A standardized multidisciplinary HF team-based approach should be incorporated to optimize the structure, minimize the redundancy of clinical responsibilities among team members, and improve clinical outcomes and patient satisfaction in their HF care.

Timing of sedation and patient-reported pain outcomes during cardiac catheterization: Results from the UNTAP-intervention study.

BACKGROUND: Invasive cardiac catheterization (CC) temporarily increases pain, discomfort, and anxiety. Procedural sedation is deployed to mitigate these symptoms, though practice varies. Research evaluating peri-procedural patient-reported outcomes is lacking. METHODS AND RESULTS: We randomized 175 patients undergoing CC to short interval ([SI] group, <6 min) or long interval ([LI] group, ≥6 min) time intervals between initial intravenous sedation and local anesthetic administration. Outcomes included: (1) total pain medication use, (2) patient-reported and behaviorally assessed pain and (3) patient satisfaction during outpatient CC. Generalized linear mixed effect models were used to evaluate the impact of treatment time interval on total medication utilization, pain, and satisfaction. Among enrollees the mean age was 62 (standard deviation [SD] = 13.4), a majority were male (66%), white (74%), and overweight (mean body mass index = 28.5 [SD = 5.6]). Total pain medication use did not vary between treatment groups (p = 0.257), with no difference in total fentanyl (p = 0.288) or midazolam (p = 0.292). Post-treatment pain levels and nurse-observed pain were not statistically significant between groups (p = 0.324 & p = 0.656, respectively. No significant differences with satisfaction with sedation were found between the groups (p = 0.95) Patient-reported pain, satisfaction and nurse-observed measures of pain did not differ, after adjustment for demographic and procedural factors. Analyses of treatment effect modification revealed that postprocedure self-reported pain levels varied systematically between individuals undergoing percutaneous coronary intervention (PCI) (SI = 2.2 [0.8, 3.6] vs. LI = 0.7 [-0.6, 2.0]) compared with participants not undergoing PCI (SI = 0.4 [-0.8, 1.7] vs. LI = 0.7 [-0.3, 1.6]) (p = 0.043 for interaction). CONCLUSION: No consistent treatment differences were found for total medication dose, pain, or satisfaction regardless of timing between sedation and local anesthetic. Treatment moderations were seen for patients undergoing PCI. Further investigation of how procedural and individual factors impact the patient experience during CC is needed.

Effects of Lifestyle Modification on Patients With Resistant Hypertension: Results of the TRIUMPH Randomized Clinical Trial.

BACKGROUND: Although lifestyle modifications generally are effective in lowering blood pressure (BP) among patients with unmedicated hypertension and in those treated with 1 or 2 antihypertensive agents, the value of exercise and diet for lowering BP in patients with resistant hypertension is unknown. METHODS: One hundred forty patients with resistant hypertension (mean age, 63 years; 48% female; 59% Black; 31% with diabetes; 21% with chronic kidney disease) were randomly assigned to a 4-month program of lifestyle modification (C-LIFE [Center-Based Lifestyle Intervention]) including dietary counseling, behavioral weight management, and exercise, or a single counseling session providing SEPA (Standardized Education and Physician Advice). The primary end point was clinic systolic BP; secondary end points included 24-hour ambulatory BP and select cardiovascular disease biomarkers including baroreflex sensitivity to quantify the influence of the baroreflex on heart rate, high-frequency heart rate variability to assess vagally mediated modulation of heart rate, flow-mediated dilation to evaluate endothelial function, pulse wave velocity to assess arterial stiffness, and left ventricular mass to characterize left ventricular structure. RESULTS: Between-group comparisons revealed that the reduction in clinic systolic BP was greater in C-LIFE (-12.5 [95% CI, -14.9 to -10.2] mm Hg) compared with SEPA(-7.1 [-95% CI, 10.4 to -3.7] mm Hg) (P=0.005); 24-hour ambulatory systolic BP also was reduced in C-LIFE (-7.0 [95% CI, -8.5 to -4.0] mm Hg), with no change in SEPA (-0.3 [95% CI, -4.0 to 3.4] mm Hg) (P=0.001). Compared with SEPA, C-LIFE resulted in greater improvements in resting baroreflex sensitivity (2.3 ms/mm Hg [95% CI, 1.3 to 3.3] versus -1.1 ms/mm Hg [95% CI, -2.5 to 0.3]; P<0.001), high-frequency heart rate variability (0.4 ln ms2 [95% CI, 0.2 to 0.6] versus -0.2 ln ms2 [95% CI, -0.5 to 0.1]; P<0.001), and flow-mediated dilation (0.3% [95% CI, -0.3 to 1.0] versus -1.4% [95% CI, -2.5 to -0.3]; P=0.022). There were no between-group differences in pulse wave velocity (P=0.958) or left ventricular mass (P=0.596). CONCLUSIONS: Diet and exercise can lower BP in patients with resistant hypertension. A 4-month structured program of diet and exercise as adjunctive therapy delivered in a cardiac rehabilitation setting results in significant reductions in clinic and ambulatory BP and improvement in selected cardiovascular disease biomarkers.

Depressive symptoms in lung transplant recipients: trajectory and association with mortality and allograft dysfunction.

OBJECTIVE: Most studies observing an association between depressive symptoms following lung transplantation and mortality are limited to depressive symptom measurement at a single time point, unrelated to allograft function. We aimed to test the association of depressive symptoms over multiple assessments with allograft dysfunction and with mortality. METHODS: We assessed depressive symptoms before and serially up to 3 years after lung transplantation in lung transplant recipients. We quantified depressive symptoms with the Geriatric Depression Scale (GDS; range 0-15; minimally important difference (MID): 2). We quantified changes in GDS using linear mixed effects models and tested the association with mortality using Cox proportional hazards models with GDS as a time-dependent predictor. To determine if worsening in GDS preceded declines in lung function, we tested the association of GDS as a time-dependent predictor with the lagged outcome of FEV1 at the following study visit. RESULTS: Among 266 participants, depressive symptoms improved early after transplantation. Worsening in post-transplant GDS by the MID was associated with mortality (HR 1.25, 95% CI 1.05 to 1.50), and in lagged outcome analyses with decreased per cent predicted FEV1 (Δ, -1.62%, 95% CI -2.49 to -0.76). Visual analyses of temporal changes in GDS demonstrated that worsening depressive symptoms could precede chronic lung allograft dysfunction. CONCLUSIONS: Depressive symptoms generally improve after lung transplantation. When they worsen, however, there is an association with declines in lung function and mortality. Depression is one of the few, potentially modifiable, risk factors for chronic lung allograft dysfunction and death.

Longer term benefits of exercise and escitalopram in the treatment of anxiety in patients with coronary heart disease: Six month follow-up of the UNWIND randomized clinical trial.

BACKGROUND: Anxiety is a common comorbidity in patients with coronary heart disease (CHD) and is associated with worse prognosis. However, effective treatment for anxiety in CHD patients is uncertain. The UNWIND randomized clinical trial showed that 12-week treatment of escitalopram was better than exercise training or placebo in reducing anxiety in anxious CHD patients. The longer-term benefits of treatment for anxiety are not known. METHODS: Patients were randomized to 12 weeks of Escitalopram (up to 20 mg), Exercise (3 times/wk), or placebo pill. At the conclusion of treatment, participants were followed for 6-months to determine the persistence of benefit on the primary anxiety endpoint assessed by the Hospital Anxiety and Depression Scale-Anxiety scale (HADS-A) and to assess the effects of treatment on major adverse cardiac events over a follow-up period of up to 6 years. RESULTS: Of the 128 participants initially randomized, 120 (94%) were available for follow-up. Participants randomized to the Escitalopram condition exhibited lower HADS-A scores (3.9 [3.1, 4.7]) compared to those randomized to Exercise (5.5 [4.6, 6.3]) (P = .007) and Placebo (5.3 [4.1, 6.5]) (P = .053). Over a median follow-up of 3.2 years (IQR: 2.3, 4.5), there were 29 adverse events but no significant between-group differences. CONCLUSION: In the UNWIND trial, 12 weeks of escitalopram treatment was effective in reducing anxiety. These beneficial effects were sustained for 6 months posttreatment. Although moderate or vigorous physical activity has a number of health benefits, exercise was not an effective treatment for anxiety in patients with CHD.

Relationship Between Depression/Anxiety and Cognitive Function Before and 6 Weeks After Major Non-Cardiac Surgery in Older Adults.

OBJECTIVE: To determine the relationship between affective measures and cognition before and after non-cardiac surgery in older adults. METHODS: Observational prospective cohort study in 103 surgical patients age ≥ 60 years old. All participants underwent cognitive testing, Center for Epidemiologic Studies-Depression, and State Anxiety Inventory screening before and 6 weeks after surgery. Cognitive test scores were combined by factor analysis into 4 cognitive domains, whose mean was defined as the continuous cognitive index (CCI). Postoperative global cognitive change was defined by CCI change from before to after surgery, with negative CCI change indicating worsened postoperative global cognition and vice versa. RESULTS: Lower global cognition before surgery was associated with greater baseline depression severity (Spearman's r = -0.30, p = 0.002) and baseline anxiety severity (Spearman's r = -0.25, p = 0.010), and these associations were similar following surgery (r = -0.36, p < 0.001; r = -0.26, p = 0.008, respectively). Neither baseline depression or anxiety severity, nor postoperative changes in depression or anxiety severity, were associated with pre- to postoperative global cognitive change. CONCLUSIONS: Greater depression and anxiety severity were each associated with poorer cognitive performance both before and after surgery in older adults. Yet, neither baseline depression or anxiety symptoms, nor postoperative change in these symptoms, were associated with postoperative cognitive change.

Preoperative opioid usage predicts markedly inferior outcomes 2 years after reverse total shoulder arthroplasty.

BACKGROUND: Reverse total shoulder arthroplasty (RTSA) has proved to be a highly effective treatment for rotator cuff-deficient conditions and other end-stage shoulder pathologies. With value-based care emerging, identifying predictive factors of outcomes is of great interest. Although preoperative opioid use has been shown to predict inferior outcomes after anatomic total shoulder arthroplasty and rotator cuff repair, there is a paucity of data regarding its effect on outcomes after RTSA. We analyzed a series of RTSAs to determine the influence of preoperative opioid use on clinical and radiographic outcomes at a minimum of 2 years' follow-up. METHODS: A retrospective review of primary RTSA patient data revealed 264 patients with ≥2 years of clinical and radiographic follow-up. Patients were classified as preoperative opioid users (71 patients) if they had taken narcotic pain medication for a minimum of 3 months prior to surgery or as opioid naive (193 patients) at the time of surgery. Assessments included preoperative and postoperative visual analog scale pain scores, American Shoulder and Elbow Surgeons scores, strength, and range of motion, as well as complications and revisions. Radiographs were analyzed for signs of loosening or mechanical failure. The Mann-Whitney U and Fisher exact tests were used for comparisons between groups. Statistical significance was set at P < .05. RESULTS: The mean patient age was 69.9 years, and the mean follow-up time was 2.8 years. Opioid users were significantly younger (66.1 years vs. 70.7 years, P < .001) at the time of surgery and had significantly higher preoperative rates of mood disorders, chronic pain disorders, and disability status (all P < .05). Postoperatively, opioid users had inferior visual analog scale pain scores (2.59 vs. 1.25, P < .001), American Shoulder and Elbow Surgeons scores (63.2 vs. 75.2, P < .001), active forward elevation (P < .001), and internal and external rotational shoulder strength (all P < .05) compared with opioid-naive patients. Periprosthetic radiolucency (8.45% vs. 2.07%, P = .026) and subsequent revision arthroplasty (14.1% vs. 4.66%, P = .014) occurred more frequently in opioid users than in opioid-naive patients. Both groups improved from baseline preoperatively to most recent follow-up in terms of functional outcomes and pain. CONCLUSION: Preoperative opioid use portended markedly inferior clinical outcomes in patients undergoing RTSA. Additionally, opioid users had significantly increased rates of periprosthetic radiolucency and revision. Preoperative opioid use appears to be a significant marker for adverse outcomes after RTSA.

Carotid Intima-Media Thickness Progression as Surrogate Marker for Cardiovascular Risk: Meta-Analysis of 119 Clinical Trials Involving 100 667 Patients.

BACKGROUND: To quantify the association between effects of interventions on carotid intima-media thickness (cIMT) progression and their effects on cardiovascular disease (CVD) risk. METHODS: We systematically collated data from randomized, controlled trials. cIMT was assessed as the mean value at the common-carotid-artery; if unavailable, the maximum value at the common-carotid-artery or other cIMT measures were used. The primary outcome was a combined CVD end point defined as myocardial infarction, stroke, revascularization procedures, or fatal CVD. We estimated intervention effects on cIMT progression and incident CVD for each trial, before relating the 2 using a Bayesian meta-regression approach. RESULTS: We analyzed data of 119 randomized, controlled trials involving 100 667 patients (mean age 62 years, 42% female). Over an average follow-up of 3.7 years, 12 038 patients developed the combined CVD end point. Across all interventions, each 10 µm/y reduction of cIMT progression resulted in a relative risk for CVD of 0.91 (95% Credible Interval, 0.87-0.94), with an additional relative risk for CVD of 0.92 (0.87-0.97) being achieved independent of cIMT progression. Taken together, we estimated that interventions reducing cIMT progression by 10, 20, 30, or 40 µm/y would yield relative risks of 0.84 (0.75-0.93), 0.76 (0.67-0.85), 0.69 (0.59-0.79), or 0.63 (0.52-0.74), respectively. Results were similar when grouping trials by type of intervention, time of conduct, time to ultrasound follow-up, availability of individual-participant data, primary versus secondary prevention trials, type of cIMT measurement, and proportion of female patients. CONCLUSIONS: The extent of intervention effects on cIMT progression predicted the degree of CVD risk reduction. This provides a missing link supporting the usefulness of cIMT progression as a surrogate marker for CVD risk in clinical trials.

Psychosocial considerations in the assessment of hand transplant candidates: A single-center experience and brief literature review.

Vascularized composite allograft, including hand transplantation (HT), has gained wider usage as a reconstructive treatment over the past 30 years. HT recipients face unique psychosocial challenges compared to their solid organ and/or bone marrow transplant counterparts. Accordingly, the psychosocial evaluation among HT candidates continues to evolve, leaving a lack of consensus as to the critical psychosocial domains and psychometric testing instruments to help evaluate individuals considering HT. The present manuscript describes the psychosocial evaluation process within the Duke HT program, which been contacted by 80 potential candidates since 2014. The Duke HT evaluation process incorporates a comprehensive psychosocial assessment within domains including personality, cognitive function, mood, behavioral adherence, social support, and substance use history, among others. Our experience underscores the potential utility of collecting thorough psychosocial evaluations, supplemented by psychometric test data, to comprehensively assess potential HT candidates.

Mobile health technology to improve emergent frailty after lung transplantation.

We evaluated the feasibility, safety, and efficacy of a mHealth-supported physical rehabilitation intervention to treat frailty in a pilot study of 18 lung transplant recipients. Frail recipients were defined by a short physical performance battery (SPPB score ≤7). The primary intervention modality was Aidcube, a customizable rehabilitation mHealth platform. Our primary aims included tolerability, feasibility, and acceptability of use of the platform, and secondary outcomes were changes in SPPB and in scores of physical activity, and disability measured using the Duke Activity Status Index (DASI) and Lung Transplant-Value Life Activities (LT-VLA). Notably, no adverse events were reported. Subjects reported the app was easy to use, usability improved over time, and the app enhanced motivation to engage in rehabilitation. Comments highlighted the complexities of immediate post-transplant rehabilitation, including functional decline, pain, tremor, and fatigue. At the end of the intervention, SPPB scores improved a median of 5 points from a baseline of 4. Physical activity and patient-reported disability also improved. The DASI improved from 4.5 to 19.8 and LT-VLA score improved from 2 to 0.59 at closeout. Overall, utilization of a mHealth rehabilitation platform was safe and well received. Remote rehabilitation was associated with improvements in frailty, physical activity and disability. Future studies should evaluate mHealth treatment modalities in larger-scale randomized trials of lung transplant recipients.

Epilepsy beliefs and misconceptions among patient and community samples in Uganda.

OBJECTIVE: The objective of the study was to characterize and compare the attitudes, beliefs, and perceptions about epilepsy across community and patient cohorts in Uganda. METHODS: This was a descriptive study utilizing two samples: a randomly selected, national survey community sample and a hospital-based patient sample of people with epilepsy (PWE) and their caregivers attending clinic settings in Kampala and Mbarara, Uganda for epilepsy care. Both samples were surveyed about their beliefs about epilepsy, its treatment, and people who have the illness. Multivariate linear regression was used to examine group differences and variables associated with specific beliefs. RESULTS: Among the 15,818 community survey participants who participated in this study, 435 study participants reported symptoms suggestive of recurrent seizures, and all 626 subjects in the hospital-based sample had confirmed epilepsy. Results revealed significant differences across groups in their endorsement of epilepsy as a contagion; 37% of people in the community unaffected by epilepsy, and 39% of people with suspected epilepsy who did not seek care believed that epilepsy was contagious by touch, in contrast to 8% of PWE or their caregivers attending regular hospital-based care. Higher educational attainment and income, and seeking regular hospital-based medical care were associated with less endorsement of epilepsy as a contagion, while age, education, income, area of residence, and presence of seizure symptoms, were significant predictors of support or belief in the basic rights of PWE. Study participants within the community who screened negative for seizures placed the most restrictions on rights for PWE. To varying degrees, the samples all endorsed the effectiveness of allopathic, traditional, and religious providers, and the use of pharmaceutical drugs, traditional rituals and herbs, and prayer. CONCLUSIONS: People with epilepsy who are attending biomedical care for routine epilepsy care think differently about epilepsy, its treatment, and the rights of those with the disease than the general population. Within the community setting, more erroneous beliefs and negative attitudes about epilepsy and PWE persist, and they not only contribute to stigma but also interfere with the patients' health-seeking behavior. Further confounding the care of PWE, the pluralistic healthcare system in Uganda is evident in endorsements spanning biomedical, traditional, and religious treatment methods. Focused awareness campaigns utilizing local epilepsy societies are needed to promote epilepsy health literacy, to favorably impact acceptance and opportunities for PWE in Uganda, and to facilitate efficient uptake of biomedical care.

Barriers to biomedical care for people with epilepsy in Uganda: A cross-sectional study.

OBJECTIVE: Epilepsy, a neurological disorder with effective biomedical treatment, remains largely untreated in Uganda. Potential reasons for this treatment gap (TG) include limited access to trained providers and clinics, social stigmata of seizures, cultural beliefs, or lack of public understanding of epilepsy as a treatable condition. The current study aimed to formally evaluate barriers faced by people with epilepsy (PWE) in Uganda when seeking biomedical care. METHODS: In a cross-sectional study, 435 participants drawn from a community prevalence study were enrolled. We included participants reporting a history of recurrent seizures suggestive of epilepsy, who completed a survey about barriers to obtaining care for their symptoms. Principal axis factor analysis (PFA) using a promax rotation was conducted for data reduction. Frequencies of barrier factors were compared across those who did not seek care for epilepsy (n = 228), those who sought care from biomedical facilities (n = 166), and those who sought care from a traditional or pastoral healer (n = 41). RESULTS: The PFA yielded a five-factor solution: 1) logistical and actual costs; 2) treatment effectiveness; 3) influence of the opinion of others; 4) doctors' care; and 5) contextual factors impacting decision-making. Variables related to logistical and actual costs were most endorsed. Comparison of groups by care sought did not reveal a difference in endorsement of factors, with the exception that those who sought biomedical care were more likely to endorse factors related to doctors' care compared with those that sought care from traditional or pastoral healers (P = .005). CONCLUSIONS: People with repetitive seizures in Uganda report several barriers to obtaining biomedical care in Uganda, with those related to practical and actual costs endorsed the most. It is imperative that interventions developed to reduce the TG in Uganda consider these practical issues to improve access to effective epilepsy care.

Pluralistic and singular causal attributions for epilepsy in Uganda.

OBJECTIVE: In Uganda, causal attributions for epilepsy reflect a variety of beliefs and impact care-seeking behavior, perpetuate stigma, and undermine the effectiveness of interventions to narrow the epilepsy treatment gap. The objective of this study was to characterize beliefs about seizure etiology to gain a better understanding of how epilepsy is conceptualized in the community in order to inform culturally appropriate educational policies and interventions. METHODS: In a community-based study, 15,383 participants were surveyed about beliefs related to 15 potential causes for epilepsy. Principal axis factor analysis (PFA) was performed to identify causative factors and then utilized to classify singular versus pluralistic belief systems related to epilepsy etiology. Analysis of variance (ANOVA) and Mann-Whitney U-tests were conducted to examine the differences in background characteristics across the etiology belief groups. RESULTS: Three main causative factors emerged from the PFA: biological, sociospiritual, and biospiritual. Among those endorsing at least one factor (n = 13,036), the biological factor was endorsed most frequently as a potential cause for epilepsy (88.0%), followed by the sociospiritual (63.4%), then biospiritual (47.6%). Review of the patterns of endorsement found that only 22.2% endorsed the biological factor alone, 6.7% the sociospiritual factor alone, and 2.8% the biospiritual factor alone (total 31.7%). The remainder endorsed a combination of two or all three factors as being potentially causal, and most (65.7%) endorsed a pluralistic combination inclusive of a biological etiology. Group comparisons showed that endorsing only the biological factor was associated with the highest levels of education (p < 0.01), the pluralistic group had the highest ratio of people in the household who needed assistance to those that could provide aid (p < 0.01), and there were significant differences in income across specific groups (p < 0.01). CONCLUSIONS: Pluralistic attributions for epilepsy are common in Uganda, with the majority of community members drawing from biomedical and traditional concepts to construct complex explanations for seizures that transcend discrete belief categories traditionally depicted in the literature. These findings emphasize the need to understand cultural beliefs about epilepsy in order to design contextually specific interventions and education programs, which respect the fundamental beliefs and values of the community.

Hospital-based epilepsy care in Uganda: A prospective study of three major public referral hospitals.

OBJECTIVE: This study sets out to describe the current demographics of people with epilepsy (PWE) attending hospital-based care in Uganda and the epilepsy treatment practices within three of the largest Ugandan public referral hospitals. METHODS: In a six-month prospective cohort study, 626 children and adults attending epilepsy clinics at Mulago National Referral Hospital, Butabika National Referral Mental Hospital and Mbarara Regional Referral Hospital were enrolled. Using a study questionnaire, data were collected at baseline and at 3 weeks, 3 months, and 6 months following enrollment. Specific data surrounding individual patient demographics, clinical characteristics and severity of epilepsy, and treatment of epilepsy with antiepileptic drugs (AEDs) were collected. RESULTS: Female patients totaled to 50.8%, with a nearly equal gender distribution at each hospital. There was no statistical difference in gender or age between sites. The majority of PWE had completed primary school, with less than 15% of patients completing more than a secondary education. Seizure severity was high, with most patients having multiple seizures per week at the initial onset of epilepsy, and greater than 90% of patients reporting a loss of consciousness with seizures. The majority of patients (54.95%) also reported a developmental or learning delay. Most patients were on 1 AED (46.01%) or 2 AEDs (36.90%), with carbamazepine being the most frequently prescribed AED. There was a trend towards improved seizure severity over the follow-up period, as assessed by the corresponding Personal Impact of Epilepsy Scale (PIES) subscale. CONCLUSIONS: People with epilepsy attending hospital-based care in Uganda tend to have severe forms of epilepsy requiring management with AEDs. Current hospital-based practices show a positive trend for seizure burden and quality of life of PWE in Uganda. Further interventions to improve overall access to biomedical care are required to continue to advance the management of PWE across all communities.

Sociocultural determinants and patterns of healthcare utilization for epilepsy care in Uganda.

OBJECTIVE: Epilepsy is a global public health concern, with the majority of cases occurring in lower- and middle-income countries where the treatment gap remains formidable. In this study, we simultaneously explore how beliefs about epilepsy causation, perceived barriers to care, seizure disorder characteristics, and demographics influence the initial choice of healthcare for epilepsy and its impact on attaining biomedical care (BMC). METHODS: This study utilized the baseline sample (n = 626) from a prospective cohort study of people with epilepsy (PWE) attending three public hospitals in Uganda (Mulago National Referral Hospital, Butabika National Referral Mental Hospital, and Mbarara Regional Referral Hospital) for epilepsy care. Patient and household demographics, clinical seizure disorder characteristics, and sociocultural questionnaires were administered. Logistic regression and principal component analyses (PCA) were conducted to examine associations with the choice of primary seizure treatment. RESULTS: The sample was 49% female, and 24% lived in rural settings. A biomedical health facility was the first point of care for 355 (56.7%) participants, while 229 (36.6%) first sought care from a traditional healer and 42 (6.7%) from a pastoral healer. Preliminary inspection of candidate predictors using relaxed criteria for significance (p < 0.20) identified several factors potentially associated with a greater odds of seeking BMC first. Demographic predictors included older caredriver (decision-maker for the participant) age (odds ratio [OR]: 1.01, 95% confidence interval [CI]: [0.99, 1.02], p-value: 0.09), greater caredriver education level (OR = 1.21, 95% CI: [1.07, 1.37], p-value = 0.003), and lower ratio of sick to healthy family members (OR = 0.77 [0.56, 1.05], P = 0.097). For clinical predictors, none of the proposed predictors associated significantly with seeking BMC first. Self-report causation predictors associated with a greater odds of seeking BMC first included higher belief in biological causes of epilepsy (OR = 1.31 [0.92, 1.88], P = 0.133) and lower belief in socio-spiritual causes of epilepsy (OR = 0.68 [0.56, 0.84], P < 0.001). In the multivariate model, only higher caredriver education (OR = 1.19 [1.04, 1.36], P = 0.009) and lower belief in socio-spiritual causes of epilepsy (OR = 0.69 [0.56, 0.86], P < 0.01) remained as predictors of seeking BMC first. Additionally, PCA revealed a pattern which included high income with low beliefs in nonbiological causes of epilepsy as being associated with seeking BMC first (OR = 1.32 [1.12, 1.55], p = 0.001). Despite reaching some form of care faster, individuals seeking care from traditional or pastoral healers experienced a significant delay to eventual BMC (P < 0.001), with an average delay of more than two years (traditional healer: 2.53 years [1.98, 3.24]; pastoral care: 2.18 [1.21, 3.91]). CONCLUSIONS: Coupled with low economic and educational status, belief in spiritual causation of epilepsy is a dominant determinant of opting for traditional or pastoral healing over BMC, regardless of concurrent belief in biological etiologies. There is a prolonged delay to eventual BMC for PWE who begin their treatment seeking with nonallopathic providers, and although nonallopathic healers provide PWE with benefits not provided by BMC, this notable delay likely prevents earlier administration of evidence-based care with known efficacy. Based on these findings, initiatives to increase public awareness of neurobiological causes of epilepsy and effectiveness of biomedical drug treatments may be effective in preventing delays to care, as would programs designed to facilitate cooperation and referral among traditional, faith-based, and biomedical providers.

Incorporating patient and caregiver feedback into lung transplant referral guidelines for individuals with cystic fibrosis-Preliminary findings from a novel paradigm.

BACKGROUND: Lung transplantation is a common therapeutic option for individuals with cystic fibrosis (CF) and advanced lung disease, yet many individuals with CF are not appropriately referred for evaluation. The present study sought to enhance CF transplant referral guidelines by integrating patient-centered input to identify possible psychosocial barriers contributing to suboptimal referral for appropriate CF transplant candidates. METHODS: As a component of developing the Cystic Fibrosis Foundation (CFF) Lung Transplant Referral Consensus Guidelines, we convened a focus group of lung transplant recipients with CF and two spouses of CF recipients. Each session involved standardized approaches to elicit qualitative, thematic content. RESULTS: CF patients and caregivers characterized five areas for improvement, which were integrated into formal CFF referral guidelines. These included (a) timing of transplant discussion with CF providers, (b) accuracy of transplant-related knowledge and expectations, (c) stigma associated with the need for transplantation, (d) treatment team transition issues, and (e) social support and mental health concerns. Earlier introduction of transplant, greater details regarding manageable aspects of treatment, and greater provision of social support were all associated with better psychosocial experiences. CONCLUSIONS: Integrating patient-centered input into guideline development yielded important and previously unknown psychosocial barriers contributing to suboptimal transplant referral.

Depression, Immunosuppressant Levels, and Clinical Outcomes in Postlung Transplant Recipients.

OBJECTIVE: Posttransplant depression has been linked to increased risk for adverse outcomes in lung transplant patients. Maintaining target serum immunosuppressant levels is also essential for optimal lung transplant clinical outcome and may be a crucial predictor of outcomes. Because depression could affect medication nonadherence, resulting in out-of-range immunosuppressant levels, we examined the relationship between posttransplant depression, immunosuppressant medication trough level variability, indexed by out-of-range values on clinical outcomes and coefficient of variability, and clinical outcomes. METHOD: A consecutive series of 236 lung transplant recipients completed the Center for Epidemiological Studies-Depression two-month posttransplant. Immunosuppressant trough levels (i.e., tacrolimus or cyclosporine) within the range of individualized immunosuppressant targets were obtained at three-, six-, nine-month follow-up clinic visits. Clinical outcomes including hospitalizations and mortality were obtained from medical records. RESULTS: Fourteen percent of patients were classified as depressed (Center for Epidemiological Studies-Depression ≥16), 144 (61%) of patients had at least 25% out-of-range immunosuppressant values, and the average coefficient of variability was 36%. Over a median of 2.6 years (interquartile range = 1.2), 32 participants died (14%) and 144 (61%) had at least one unplanned, transplant-related hospitalization. Both depression (hazard ratio = 1.45 (1.19, 1.76), p < . 01) and immunosuppressant variation (immunosuppressant out-of-range: hazard ratio = 1.41 (1.10, 1.81), p < .01) independently predicted more frequent hospitalizations and higher mortality. CONCLUSIONS: Early posttransplant depression was associated with significantly worse clinical outcomes. While immunosuppressant level variability is also related to adverse outcomes, such variability does not account for increased risk observed with depression.

Reactive Inkjet Printing of Functional Silk Stirrers for Enhanced Mixing and Sensing.

Stirring small volumes of solution can reduce immunoassay readout time, homogenize cell cultures, and increase enzyme reactivity in bioreactors. However, at present many small scale stirring methods require external actuation, which can be cumbersome. To address this, here, reactive inkjet printing is shown to be able to produce autonomously rotating biocompatible silk-based microstirrers that can enhance fluid mixing. Rotary motion is generated either by release of a surface active agent (small molecular polyethylene glycol) resulting in Marangoni effect, or by catalytically powered bubble propulsion. The Marangoni driven devices do not require any chemicals to be added to the fluid as the "fuel," while the catalytically powered devices are powered by decomposing substrate molecules in solution. A comparison of Marangoni effect and enzyme powered stirrers is made. Marangoni effect driven stirrers rotate up to 600 rpm, 75-100-fold faster than enzyme driven microstirrers, however enzyme powered stirrers show increased longevity. Further to stirring applications, the sensitivity of the motion generation mechanisms to fluid properties allows the rotating devices to also be exploited for sensing applications, for example, acting as motion sensors for water pollution.
