• First controlled trial of respiratory muscle training in late-onset Pompe disease. • Respiratory muscle training is safe and well-tolerated. • Increases in respiratory muscle strength larger in treatment vs sham subjects though not statistically significant. • Sham respiratory muscle training may not be an optimal control condition. • A larger sample stratified by disease severity is needed in future research. To address progressive respiratory muscle weakness in late-onset Pompe disease (LOPD), we developed a 12-week respiratory muscle training (RMT) program. In this exploratory, double-blind, randomized control trial, 22 adults with LOPD were randomized to RMT or sham-RMT. The primary outcome was maximum inspiratory pressure (MIP). Secondary and exploratory outcomes included maximum expiratory pressure (MEP), peak cough flow, diaphragm ultrasound, polysomnography, patient-reported outcomes, and measures of gross motor function. MIP increased 7.6 cmH 2 O (15.9) in the treatment group and 2.7 cmH 2 O (7.6) in the control group (P = 0.4670). MEP increased 14.0 cmH 2 O (25.9) in the treatment group and 0.0 cmH 2 O (12.0) in the control group (P = 0.1854). The only statistically significant differences in secondary/exploratory outcomes were improvements in time to climb 4 steps (P = 0.0346) and daytime sleepiness (P = 0.0160). The magnitude of changes in MIP and MEP in the treatment group were consistent with our pilot findings but did not achieve statistical significance in comparison to controls. Explanations for this include inadequate power and baseline differences in subject characteristics between groups. Additionally, control group subjects appeared to exhibit an active response to sham-RMT and therefore sham-RMT may not be an optimal control condition for RMT in LOPD. [ABSTRACT FROM AUTHOR]

Background: A small but growing body of evidence supports a relationship between neighborhood socioeconomic status (NSES) and cognitive decline. Additional work is needed to characterize this relationship controlling for risk factors such as cardiovascular, cerebrovascular, and genetic risk factors. Methods: Cognitive decline was assessed in association with NSES, and cardiovascular and cerebrovascular risk factors (heart disease, diabetes, hypertension, and stroke) in 8,198 individuals from the 1992–2010 waves of the Health and Retirement Study (HRS). Latent class trajectory analysis determined the number of cognitive trajectory classes that best fit the data, and a multinomial logistic regression model in the latent class framework assessed the risk for cognitive classes conferred by NSES index score and heart disease, diabetes, hypertension, and stroke across three trajectory classes of cognitive function. The analyses controlled for genetic risk for cognitive decline (including APOE genotype) and demographic variables, including education. Results: The HRS sample was 57.6% female and 85.5% White, with a mean age of 67.5(3.5) years at baseline. The three-quadratic-class model best fit the data, where higher classes represented better cognitive function. Those with better cognitive function were mainly younger white females. Those in the highest quartile of NSES had 57% higher odds of being in the high cognitive function class. Heart disease, diabetes, hypertension, and stroke each increased the odds having of lower cognitive function. Conclusions: In examining the relationship of cognitive status with various variables, neighborhood socioeconomic status, cardiovascular risk, and cerebrovascular risk persisted across the cognitive trajectory classes.

Morbidity and mortality in adults with late-onset Pompe disease (LOPD) results primarily from persistent progressive respiratory muscle weakness despite treatment with enzyme replacement therapy (ERT). To address this need, we have developed a 12-week respiratory muscle training (RMT) program that provides calibrated, individualized, and progressive pressure-threshold resistance against inspiration and expiration. Our previous results suggest that our RMT regimen is safe, well-tolerated, and results in large increases in respiratory muscle strength. We now conduct an exploratory double-blind, randomized control trial (RCT) to determine: 1) utility and feasibility of sham-RMT as a control condition, 2) the clinically meaningful outcome measures for inclusion in a future efficacy trial. This manuscript provides comprehensive information regarding the design and methods used in our trial and will aid in the reporting and interpretation of our future findings. Twenty-eight adults with LOPD will be randomized (1:1) in blocks of 4 to RMT (treatment) or sham-RMT (control). Assessments will be conducted at pretest, posttest, 3-months detraining, and 6-months detraining. The primary outcome is maximum inspiratory pressure (MIP). Secondary outcomes include maximum expiratory pressure (MEP), 6-min walk test (6MWT), Gait, Stairs, Gowers, and Chair test (GSGC), peak cough flow (PCF), and patient-reported life activity/social participation (Rasch-built Pompe-specific Activity scale [R-Pact]). Exploratory outcomes include quantitative measures from polysomnography; patient reported measures of fatigue, daytime sleepiness, and sleep quality; and ultrasound measures of diaphragm thickness. This research will use a novel tool to provide automated data collection and user feedback, and improve control over dose. The results of this clinical trial will be promptly analyzed and submitted for publication. Results will also be made available on clinicaltrials.gov. ClinicalTrials.gov : NCT02801539 , R21AR069880.

Objective: Describe social goods and services for which hospices assist patients and families and the resources hospices use to do so. Background: Basic social supports and services not routinely covered by insurers may be needed by terminally ill patients and their families. Little is known about hospices' provision of such social supports and services. Methods: A 2014-2015 cross-sectional survey of hospices nationwide. Participating hospices had been in operation for at least 3 years and were located in any of the 50 states or District of Columbia. Hospices were surveyed about availability and sources of internal funds and referral to obtain basic social supports for patients. Descriptive statistics, bivariate analysis, and categorization were used to describe hospice practices. Measures included frequency and nature of goods and services provision in the prior year; and extent to which hospices used internal funds or community referral for goods and services. Results: Over 80% (n = 203) reported internal funds covered services not reimbursed by insurers; 78% used funds in last year. Hospices used internal funds for food (81.7%), shelter (57.8%), utility bills (73.5%), and funeral costs (50%). Hospices referred patients/families to community organizations to obtain a similar range of services, including transportation, clothing, linens/towels, furniture/appliances, home repairs, and caregiver support. Discussion: Hospices are using internal resources and accessing community resources to provide patients with basic social needs not routinely covered by insurance. [ABSTRACT FROM AUTHOR]

Background: Parkinson's disease (PD) is among the most prevalent neurodegenerative conditions. While motor and nonmotor aspects of this disease have been well characterized, no objective biomarker exists to support an accurate clinical diagnosis. However, newer imaging techniques, including [123I]-FP-CIT (DaTSCAN), have demonstrated utility in differentiating between PD and non-neurodegenerative tremor disorders. Objective: DaTSCAN has been primarily investigated in situations where diagnostic confusion exists, and in these instances has been shown to significantly impact clinical management. The goal of this pilot study was to evaluate the impact of DaTSCAN on the clinical management of patients with early probable PD, where no diagnostic uncertainty exists. Methods: Thiswas a prospective, 54-week, comparative pilot study, in which twenty subjects with de novo PD were randomly assigned to DaTSCAN either immediately upon diagnosis (and again at 6 and 12 months) or delayed to 6 months (and again at 12 months). The primary outcome measure was the frequency of deviation from the initial treatment plan from baseline to 54 weeks between the two groups. Secondary outcomes included motor and non-motor assessments. Results: There was no significant difference in the number of treatment changes over the course of the study between the two groups: initial imaging group = 4.2 (SD:2.74) vs. delayed imaging group = 2.3 (SD:2.0, p = 0.11). In addition, there were no group differences in medication requirements, motor performance, or patient expectations of disease. Conclusions: In patients with early, probable PD, DaTSCAN contributes no additional impact on clinical management or functional outcomes when added to the diagnostic algorithm.

Abstract: Context: Although blacks use hospice at lower rates than whites in the U.S., racial differences in hospice use vary by geographic area. Objectives: To describe intercounty variability in black-white differences in hospice use and the association with the supply of health care resources. Methods: Subjects were a retrospective cohort of Medicare beneficiaries in North and South Carolina who died in 2008. Using Wilcoxon tests and logistic regression, we examined the differences in the supply of health care resources (hospital beds and physicians per population age 65 years and older, percentage of generalists, etc.) between counties with and without racial disparity in hospice use. Counties with a racial disparity had significantly (P < 0.05) higher rates of hospice use among whites than blacks. Results: Of 76,283 decedents in 128 counties, 19.78% were black. In the 39 counties (30.47%) with racial disparity in hospice use, the mean proportion of whites who enrolled in hospice was 41.3% vs. 28.66% of blacks (P < 0.0001). Counties with more hospital beds per population age 65 years and older had a higher odds (OR, 1.39; 95% confidence interval [CI] 1.04–1.86) and those with a larger proportion of generalists had a lower odds (OR, 0.01; 95% CI 0.001–0.476) of having a racial disparity in hospice use. Conclusion: In most counties, the rates of hospice use were similar for blacks and whites. In counties with a racial disparity, there were more resources to deliver aggressive care (i.e., hospital beds and specialists). Because of a greater preference for life-sustaining therapies, blacks may be more likely to use acute care services at the end of life when resources for the delivery of these services are readily available.

Background. It is unclear whether distinct weight-related trajectory classes, differing in course, demographics, and health characteristics, exist in the elderly population. Methods. Data came from the 10-year (1986–1996) Duke Established Populations for Epidemiologic Studies of the Elderly study of 3,861 black (54%) and white (46%) participants aged 65–105 years. Latent-class trajectories of body mass index (BMI: kg/m2) based on self-reported weight and height at baseline, 3, 6, and 10 years later were determined using generalized mixture models. Polytomous logistic regression was used to identify baseline demographic and health characteristics that distinguished the trajectories, and 10-year postbaseline data to confirm the findings. Results. We identified three trajectories: normal weight (BMI ~24, 27.6% of the sample), overweight (BMI ~26, 65.1%), and obese (BMI ~31, 7.3%). Demographic characteristics distinguished the three trajectories: highest odds of blacks, women, and less education in the obese trajectory, lowest in the normal-weight trajectory. Obese and overweight differed adversely from normal-weight trajectories, but not significantly from each other on cognitive impairment, hypertension, and diabetes. Depressive symptomatology was more prevalent in the obese; they were also younger. There was no association with cancer or heart disease. Conclusion. Distinct trajectories and course of BMI were present in this older population. Weight loss increased with increase in BMI class. Although demographic characteristics distinguished all trajectory classes, adverse health characteristics distinguished the overweight and obese classes from the normal-weight class, but not from each other. Problems associated with education and health are present at study entry and should be addressed earlier in life. [ABSTRACT FROM PUBLISHER]

African Americans are less likely than Whites to enroll in hospice. In addition, patients are often referred to hospice very close to death, when they may not have time to take advantage of the full range of hospice services. Understanding how race and location before hospice enrollment are related to hospice length of stay (LOS) may inform the development of interventions to increase timely access to hospice care. Using data from a national hospice provider, African Americans and Whites admitted to routine home hospice care in a private residence between January 1, 2000, and December 31, 2003, were identified. Logistic regression was used to examine the association between race and hospice preadmission location (hospital vs other locations) and preadmission location and hospice LOS (≤7 days vs >7 days) after adjusting for demographic and hospice use variables. Of 43,869 enrollees, 15.3% were African American. One to 2 days before hospice enrollment, African Americans were more likely than Whites to be in the hospital than in all other locations (48.6% vs 32.3%, P<.001; adjusted odds ratio=1.83, 95% confidence interval=1.73-1.95). Regardless of race, those whose preadmission location was the hospital were more likely than those from other locations to die 7 days or less after hospice enrollment. Initiatives to improve end-of-life care should focus on increasing timely access to hospice referrals in settings outside of the hospital. Future research should examine whether racial differences in hospice preadmission location reflect differences in preferences for care or disparities in timely access to hospice referrals in non-acute care settings.

Background. To ascertain accuracy of self-reported height, weight (and hence body mass index) in African American and white women and men older than 70 years of age. Method. The sample consisted of cognitively intact participants at the third in-person wave (1992-1993) of the Duke Established Populations for Epidemiologic Studies of the Elderly (age 71 and older, N = 1761; residents of five adjacent counties, one urban, four rural). During in-person, in-home interviews using trained interviewers, height and weight were self-reported (and measured later in the same visit using a standardized protocol), and information were obtained on race, sex, and age. Results. Accuracy of self-reported height and weight was high (intraclass correlation coefficient 0.85 and 0.97, respectively) but differed as a function of race and age. On average, all groups overestimated their height; whereas (non-Hispanic) white men and women underestimated their weight, African Americans overestimated their weight. Overestimation of height and weight was more marked in persons 85 years and older. Specificity for overweight (body mass index [kg/ m 2 ] ≥ 25) and obesity (body mass index ≥ 30) ranged from 0.90 to 0.99 for African Americans and whites, but sensitivity was better for African Americans (overweight: 0.81, obesity: 0.89), than for whites (0.66 and 0.57, respectively). Conclusions. Height and weight self-reported by African Americans and whites over the age of 70 can be used in epidemiological studies, with greater caution needed for self-reports of whites, and of persons 85 years of age or older.

Objectives Structural magnetic resonance imaging (MRI) studies have been inconsistent in demonstrating volumetric differences in subjects with bipolar disorder. Most studies have not found difference in total gray or white matter in bipolar patients compared with controls, but there have been several studies suggesting that regional abnormalities are present. These have predominately been located in the frontal and temporal lobes. Since age has been inversely correlated with total gray matter in patients, analyses of gray matter changes in older adults or in studies that have included older subjects have been difficult. This study assessed the presence of gray matter volume, and the potential for regional volumetric differences in older adults with bipolar disorder. Methods Fifty-six older adults with DSM-IV bipolar disorder (mean age 60.5) and 43 non-psychiatrically ill controls (mean age 58.1) had structured interviews and MRI scanning on a 1.5T GE Scanner. Image parcellation divided the cerebrum into 16 units. Volumetric differences were examined using the multivariate linear regression models with α = 0.05. Results Relative to controls, the older adults with bipolar disorder had significantly smaller gray matter volumes bilaterally in the inferior frontal areas. White matter volume was also reduced in these same areas but did not reach statistical significance when controlled for gender and age. No significant difference was noted in total gray or white matter volumes. Conclusions Older adults with bipolar disorder showed gray matter volumetric deficits in inferior frontal lobe regions which include structures identified as contributing to the anterior limbic network.

Background: Previous research suggests that lack of knowledge of hospice is a barrier to the use of hospice care by African Americans. However, there is little data examining racial differences in exposure to hospice information. Objectives: Examine racial differences in self-reported exposure to hospice information and determine how this exposure impacts beliefs about hospice care. Methods: We surveyed 200 community-dwelling older adults (65 or older). We used Spearman's correlations to examine the relationship between responses to individual items on the Hospice Beliefs and Attitudes Scale (HBAS) and self-reported exposure to hospice information (never heard of hospice, heard a little, or heard a lot). We used multivariate analyses to examine predictors of exposure to hospice information and beliefs about hospice care (total score on HBAS). Results: Compared to whites ( n = 95), African Americans ( n = 105) reported significantly less exposure to hospice information ( p = 0.0004). Nineteen percent of African Americans and 4% of whites had never heard of hospice; 47.6% of African Americans and 71.6% of whites had heard a lot about hospice. In multivariate analysis controlling for demographics and health status, African Americans had a two times higher odds of reporting that they had never heard of hospice or heard only a little about hospice versus heard a lot about hospice (odds ratio [OR] = 2.24 [1.17, 4.27]. Greater exposure to hospice information was associated with more favorable beliefs about hospice care (outcome: total score on HBAS; parameter estimate 1.34, standard error 0.44, p = 002). Conclusions: African Americans reported less exposure to information about hospice than whites. Greater exposure to hospice information was associated with more favorable beliefs about some aspects of hospice care. Because knowledge is power, educational programs targeting older African Americans are needed to dispel myths about hospice and to provide minorities with the tools to make informed choices about end-of-life care.

Objective Theories about the impact of stressful life events (SLE) in bipolar disorder have focused on their role early in the disease. Few studies have examined SLE in older bipolar patients. We wanted to assess the impact of SLE in late life bipolar disorder Methods We evaluated negative SLE experienced by older bipolar subjects compared with younger bipolar subjects and older controls for number, type, and their association with phase of illness, age of onset, and previous episodes. Results Both younger and older bipolar subjects have more SLE than similarly aged controls. There was no significant difference in the number of stressors that younger and older bipolar subjects experienced, based on mood state, previous episodes, or age-of-onset. Both older and younger depressed bipolar subjects reported more SLE in the previous 12 months compared with those in a manic state. Conclusions Negative SLE are much more prevalent in bipolar patients compared with age-matched controls, and continue to be frequent in later life. Copyright © 2008 John Wiley & Sons, Ltd.

Cultural beliefs and values are thought to account for differences between African Americans and whites in the use of advance directives and beliefs about hospice care, but few data clarify which beliefs and values explain these differences. Two hundred five adults aged 65 and older who received primary care in the Duke University Health System were surveyed. The survey included five scales: Hospice Beliefs and Attitudes, Preferences for Care, Spirituality, Healthcare System Distrust, and Beliefs About Dying and Advance Care Planning. African Americans were less likely than white subjects to have completed an advance directive (35.5% vs 67.4%, P<.001) and had less favorable beliefs about hospice care (Hospice Beliefs and Attitudes Scale score, P<.001). African Americans were more likely to express discomfort discussing death, want aggressive care at the end of life, have spiritual beliefs that conflict with the goals of palliative care, and distrust the healthcare system. In multivariate analyses, none of these factors alone completely explained racial differences in possession of an advance directive or beliefs about hospice care, but when all of these factors were combined, race was no longer a significant predictor of either of the two outcomes. These findings suggest that ethnicity is a marker of common cultural beliefs and values that, in combination, influence decision-making at the end of life. This study has implications for the design of healthcare delivery models and programs that provide culturally sensitive end-of-life care to a growing population of ethnically diverse older adults.

Introduction: Neuroanatomic features associated with antidepressant treatment outcomes in older depressed individuals are not well established. This study used diffusion tensor imaging to examine frontal white matter structure in depressed subjects undergoing a 12-week trial of sertraline. We hypothesized that remission would be associated with higher frontal anisotropy measures, and failure to remit with lower anisotropy. Methods: 74 subjects with Major Depressive Disorder and age 60 years or older were enrolled in a twelve-week open-label trial of sertraline and completed clinical assessments and 1.5T magnetic resonance brain imaging. The apparent diffusion coefficient (ADC) and fractional anisotropy (FA) were measured in regions of interest placed in the white matter of the dorsolateral prefrontal cortex, anterior cingulate cortex, and corpus callosum. Differences in ADC and FA values between subjects who did and did not remit to treatment over the study period were assessed using generalized estimating equations, controlling for age, sex, medical comorbidity and baseline depression severity. Results: Subjects who did not remit to sertraline exhibited higher FA values in the superior frontal gyri and anterior cingulate cortices bilaterally. There were no statistically significant associations between ADC measures and remission. Conclusions: Failure to remit to sertraline is associated with higher frontal FA values. Functional imaging studies demonstrate that depression is characterized by functional disconnection between frontal and limbic regions. Those individuals where this disconnection is related to structural changes as detected by DTI may be more likely to respond to antidepressants. [ABSTRACT FROM AUTHOR]

The article presents a study concerning the relation between racial differences and discharge disposition defined as hospice revocation to pursue aggressive care versus other all discharges. To examine this case, logistic regression and a Cox proportional hazards model were used. Research shows that the higher odds of leaving hospice to pursue life-prolonging therapies were on African American patients. Thus, it infers that hospice revocation to pursue life-prolonging therapies were more likely on African American patients than on white patients

Abstract: Patients with noncancer life-limiting illnesses now represent over half of all hospice enrollees, compared to only one-quarter of enrollees in 1992. Whether this growth in enrollees with noncancer diagnoses has been similar for Caucasians and African Americans, a group historically underrepresented in hospice, has not been described. The purpose of this study was to compare rates of noncancer diagnoses among African American and Caucasian hospice enrollees. We analyzed data from the administrative database of VITAS Healthcare Corporation, including all African Americans and Caucasians discharged from hospice between January 1, 1999 and December 31, 2003. Of the 166,390 eligible discharges, 14.6% were African American, and 85.4% were Caucasian. Over the five-year study period, there was a similar increase in the crude proportion of enrollees with noncancer diagnoses in both groups, from 42% to 49.7% among African Americans and 57.9% to 64.3% among Caucasians. However, in multivariate analysis (adjusted for age, gender, admission level of care, payment source, Health Maintenance Organization (HMO) use, discharge year, and hospice program characteristics—size, location, presence of an inpatient unit), African Americans had 32% lower odds of having a noncancer (vs. cancer) diagnosis than Caucasians (odds ratio [OR] 0.68 [0.66, 0.77]). While numerous studies document lower rates of hospice use among African Americans than Caucasians, these findings suggest disease-specific differences in patterns of hospice use, with greater disparities in hospice use among African Americans with noncancer diagnoses than those with cancer diagnoses. Targeted efforts to increase hospice use among African Americans with noncancer diagnoses may be important in reducing racial disparities in overall hospice use and improving the quality of care for dying African Americans.

Based on 88 non-demented controls and 140 AD patients enrolled at the University of Southern California, and 102 Spanish-speaking dementia patients at the University of Pennsylvania, we developed norms, stratified by disease severity, for the Spanish-language CERAD Neuropsychological Battery, and examined the impact of demographic characteristics. Adequacy of information and level of performance differed between sites, indicating hazards that occur in the absence of cross-site planning, including characteristics of "retrofitted" data (e.g., missing information), small samples, additional countries of origin, and multiple dementing disorders. Nevertheless, controls generally performed better than even very mild AD patients, and performance decreased with in- crease in severity of disease. In the absence of larger, more representative samples, norms for Spanish-speaking patients and control subjects may he site-specific, and should he treated with caution. [ABSTRACT FROM AUTHOR]

OBJECTIVES: To characterize physiological variation in hospitalized older adults with severe coronary artery disease (CAD) and evaluate the prevalence of frailty in this sample, to determine whether single-item performance measures are good indicators of multidimensional frailty, and to estimate the association between frailty and 6-month mortality. DESIGN: Observational cohort study. SETTING: Inpatient hospital cardiology ward. PARTICIPANTS: Three hundred nine consecutive inpatients aged 70 and older admitted to a cardiology service (n=309; 70% male, 84% white) with minimum two-vessel CAD determined using cardiac catheterization. MEASUREMENTS: Two standard frailty phenotypes (Composite A and Composite B), usual gait speed, grip strength, chair stands, cardiology clinical variables, and 6-month mortality. RESULTS: Prevalence of frailty was 27% for Composite A versus 63% for Composite B. Utility of single-item measures for identifying frailty was greatest for gait speed (receiver operating characteristic curve c statistic=0.89 for Composite A, 0.70 for Composite B) followed by chair-stands (c=0.83, 0.66) and grip strength (c=0.78, 0.57). After adjustment, composite scores and single-item measures were individually associated with higher mortality at 6 months. Slow gait speed (≤0.65 m/s) and poor grip strength (≤25 kg) were stronger predictors of 6-month mortality than either composite score (gait speed odds ratio (OR)=3.8, 95% confidence interval (CI)=1.1–13.1; grip strength OR=2.7, 95% CI=0.7–10.0; Composite A OR=1.9, 95% CI=0.60–6.1; chair-stand OR=1.5, 95% CI=0.5–5.1; Composite B OR=1.3, 95% CI=0.3–5.2). CONCLUSION: Gait speed frailty was the strongest predictor of mortality in a population with CAD and may add to traditional risk assessments when predicting outcomes in this population.

Background: The results of previous studies suggest structural brain differences in pediatric maltreatment-related posttraumatic stress disorder (PTSD) However, posterior fossa volumes were not examined, despite the consensus that the cerebellum is important in emotional and cognitive development. We investigated the relationship between structural volumes of the cerebellum hemispheres, vermis, brainstem, and clinical variables in pediatric maltreatment-related PTSD. Methods: Fifty-eight psychotropic-naïve maltreated children and adolescents with DSM-IV PTSD were compared with two groups of pediatric subjects who had no DSM-IV criteria A trauma histories: 1) 13 with pediatric generalized anxiety disorder, and 2) 98 healthy non-abused children and adolescents. Subjects underwent a comprehensive psychiatric assessment and an anatomical magnetic resonance image brain scan. Results: Unadjusted means of the left, right, and total cerebellum were smaller in the PTSD group. The group differences remained significant in the left cerebellum, right cerebellum, and total cerebellum in the analyses adjusted for cerebral volume, sociodemographic, and IQ variables. Cerebellar volumes positively correlated with age of onset of the trauma that lead to PTSD and negatively correlated with the duration of the trauma that lead to PTSD. Cerebellar volumes were larger in boys versus girls, but there was no group × gender interaction. There were significant positive correlations between IQ measures and volumetric variables. Conclusions: The results support cerebellar volume differences in maltreated children and adolescents with PTSD. Further studies are warranted. [Copyright &y& Elsevier]

Abstract: Purpose: To explore the impact of varying hemoglobin levels on mortality, function, and cognition in a representative population of older persons. Methods: Participants in this prospective cohort study included 1 744 men and women, aged 71 years or older, from a random household sample living in Durham and surrounding counties in North Carolina. Hemoglobin levels were obtained from participants at baseline in 1992. Functional status was measured at the 4-year follow-up interview using Katz and instrumental activities of daily living. Cognition was measured using the Short Portable Mental Status Questionnaire (SPMSQ). Death was determined by search of the National Death Index, and all deaths through 2000 are included. Results: Using World Health Organization (WHO) criteria, the prevalence of anemia was 24%. There was a strong racial difference with an odds ratio, adjusted for age, education, estimated glomerular filtration rate and comorbidity of 3.0 (95% CI, 2.3-3.9) in African Americans compared with Caucasians. The risk ratio for 8-year mortality was 1.7 (95% CI, 1.5-2.0) for anemic subjects (P = .0001) and did not differ by sex or race. Anemia was strongly associated with poorer physical function (P = .0001) and cognitive function (P = .0001), and predicted decreases in both over a 4-year period. Conclusions: In an elderly community-based population, anemia is more prevalent in African Americans and is independently associated with increased mortality over 8 years for both races and sexs. Anemia also is a risk factor for functional and cognitive decrease. [Copyright &y& Elsevier]

Purpose: This study identifies the relative importance of reasons for institutionalization endorsed by caregivers of patients with dementia; examines the relationship between caregivers' reasons for institutionalization and indicators of caregiver and patient physical and emotional functioning measured in the prior year; and compares, on these indicators, caregivers who institutionalized their care recipients with caregivers who did not. Design and Methods: Participants were 2,200 caregivers from the National Longitudinal Caregiver Study, including 580 who institutionalized their care recipient during the 3-year interval. Caregivers' reason(s) for institutionalization were examined and correlated with indicators of caregiver and patient physical and emotional functioning. These indicators were used in a proportional hazards model to determine independent predictors. Results: Caregivers' reasons for placement included (a) the need for more skilled care (65%); (b) the caregivers' health (49%); (c) the patients' dementia-related behaviors (46%); and (d) the need for more assistance (23%). Each of these reasons was significantly associated with indicators in the prior year's survey. This study uniquely demonstrates that caregiving task demand and a single-item measure of caregiver life satisfaction significantly predict placement. Implications: These findings emphasize that caregivers' reasons have valid underpinnings and that institutionalization of dementia patients results from caregiver and patient factors evident in the year prior to placement. In routine office visits, caregivers should be systematically screened; accounts of low life satisfaction, dementia problem behaviors, or high task demand should cue clinicians that discussions of nursing home placement would be timely and appropriate.

The presence of medical illnesses among inpatients with bipolar disorder is known to complicate treatment and lengthen hospital stay. However, except for a few specific diseases, little is known about prevalence of medical illnesses in bipolar outpatients and the effect it may have on treatment. The authors sought to assess the presence of medical illnesses in a large outpatient clinical sample of bipolar patients, and the effect that medical illnesses may have on the clinical assessment and treatment of the underlying bipolar disorder. Using the Duke University Medical Center clinical database, the authors categorized the medical diagnoses of 1379 patients who were treated with bipolar disorder from 2001 to 2002 through outpatient psychiatric clinics. The prevalence of medical comorbidities was examined, as well as the effect their presence had on the clinician's assessment of disease severity and time to improvement. As expected, medical comorbidities increased with age. The most common systemic illnesses in bipolar outpatients were Endocrine and Metabolic Diseases (13.6% of the sample), Diseases of the Circulatory System (13.0%), and Diseases of the Nervous System and Sense Organs (10.7%). Significant specific diseases included cardiovascular diseases/hypertension (10.7%), COPD/asthma (6.1%), diabetes (4.3%), HIV infection (2.8%), and hepatitis C infection (1.9%). Clinicians assessed greater severity of illness in patients with increasing numbers of comorbid conditions; however, the time to recovery was not significantly effected by the presence of medical comorbidity. In conclusion, comorbid medical illnesses are common in bipolar outpatients, increasing with age. HIV rates may be increased relative to population norms. Their presence compounds the severity of the illness at time of presentation. [ABSTRACT FROM AUTHOR]

Background Decreased caudate volumes have been noted in unipolar depressed subjects, especially in the elderly and those with cognitive impairment. No differences have been noted in initial studies of multi-aged bipolar subjects; however, this region has not been examined in older bipolar subjects. Methods We examined the caudate nuclei volumes of 36 older bipolar subjects (mean age 58) and 35 older controls (mean age 62) using logistic regression analyses to control for age and gender differences. Differences between late- and early-onset (age-of-onset before age 45) bipolar subjects were also examined, as well as the effect of length of illness. Results The right caudate was noted to be smaller in older bipolar subjects compared with older controls when controlled for sex and age (p = 0.0448). No differences were noted in overall brain volume nor lateral ventricular volume between the bipolar and control subjects. Late-onset bipolar subjects had a decrease in brain volume (p = 0.035) compared with early-onset bipolar subjects. Late-onset bipolar subjects had a decrease in the right (p = 0.044) and total (p = 0.04) caudate size compared with older controls. Conclusions Right caudate volume is decreased in older bipolar subjects compared to controls. Bipolar subjects with late-onset illness have significantly decreased right and total caudate volumes compared to controls. This is affected by neither the length of illness nor the age of onset. Late-onset bipolar subjects have decreased total brain volume compared with early-onset bipolar subjects. Copyright © 2004 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Objective: The role of social support in bipolar disorder is poorly understood. It is known that young and middle-aged patients with impaired social support are more likely to be treatment resistant and have increased hospitalization. However, the role of social support in elderly patients with bipolar disorder has not been studied. Our purpose was to evaluate social support in older adults with bipolar disorder compared with peer controls and younger bipolar patients. In addition, we looked at the role of social support in the age of illness onset. Methods: We evaluated social support of 29 older subjects with bipolar disorder (age 50 or older) and 56 younger subjects with bipolar disorder using the Duke Social Support Index, comparing them to non-psychiatric, peer controls. Using logistic regression we then examined the relationship of demographic, social support factors, and age of onset. Results: Both older and younger bipolar subjects perceived their social support as inadequate (OR=14.98; OR=9.05) compared with similar aged controls. Younger bipolar subjects also had less social interactions than younger controls (OR=4.63). These findings remained significant when controlled for gender, marital status, race, and education. No significant differences were noted between early-onset and late-onset bipolar subjects. Conclusions: Older and younger bipolar patients have decreased perceptions of social support than older controls. No effect was found based on the age of illness onset. In addition, younger subjects had less social interactions than peer controls. [ABSTRACT FROM AUTHOR]

Introduction: Black patients have a higher incidence of heart failure (HF) and worse outcomes than white patients. Guidelines recommend palliative care for patients with advanced HF, but no studies have examined outcomes in a black patient cohort. Methods: This is a post hoc analysis of the Palliative Care in Heart Failure trial, which randomized patients to usual care plus a palliative care intervention (UC+PAL) or usual care (UC). Quality of life (QoL) was measured using Kansas City Cardiomyopathy Questionnaire (KCCQ) and Functional Assessment of Chronic Illness Therapy-Palliative Care scale (FACIT-Pal). Results: Black patients represented 41% of the 148 patients. At six months, QoL improved more in UC+PAL than UC for both racial subgroups. The difference was greater for black than white patients (difference: KCCQ 10.8 vs. 2.5; FACIT-Pal: 14.8 vs. 3.9). However, the findings were not statistically significant. Conclusions: Larger studies are needed to assess the benefits of palliative care for black patients with HF. ClinicalTrials.gov Identifier: NCT01589601. [ABSTRACT FROM AUTHOR]

Background: Although therapeutic plasma exchange (TPE) is associated with hemostatic abnormalities, its impact on bleeding outcomes is unknown. Therefore, the main study objective was to determine bleeding outcomes of inpatients treated with TPE. Study Design and Methods: In a cross‐sectional analysis of the National Inpatient Sample (NIS), discharges were identified with 10 common TPE‐treated conditions. A 1:3 propensity‐matched analysis of TPE‐ to non‐TPE‐treated discharges was performed. The primary outcome was major bleeding and secondary outcomes were packed red blood cell (PRBC) transfusion, mortality, disposition, hospital length of stay (LOS), and charges. Multivariable regression analyses were used to examine the association between TPE and study outcomes. Results: The study population was 15,964 discharges, of which 3991 were TPE‐ treated. The prevalence of major bleeding was low (5.4%). When compared to non‐TPE discharges, TPE had a significant and positive association with major bleeding (OR = 1.37, 95% CI: 1.16–1.63, p =.0003). TPE was also associated with PRBC transfusion (OR = 1.66, 95% CI: 1.42–1.94, p <.0001), in‐hospital mortality (OR = 1.45, 95% CI: 1.10–1.90, p =.0008), hospital length of stay (12.45 [95% CI: 11.95–12.97] vs. 7.38 [95% CI: 7.12–7.65] days, p <.0001) and total charges, ($125,123 [95% CI: $119,220–$131,317] vs. $61,953 [95% CI: $59,391–$64,625], p <.0001), and disposition to non‐self‐care (OR = 1.29, 95% CI: 1.19–1.39, p <.0001). Discussion: The use of TPE in the inpatient setting is positively associated with bleeding; however, with low prevalence. Future studies should address risk factors that predispose patients to TPE‐associated bleeding. [ABSTRACT FROM AUTHOR]

Background: There is a paucity of data on older adults (age ≥65 years) undergoing surgery who had an inpatient do‐not‐resuscitate (DNR) order, and the association between timing of DNR order and outcomes. Methods: This was a retrospective analysis of 1976 older adults in the American College of Surgeons National Surgical Quality Improvement Program geriatric‐specific database (2014–2018). Patients were stratified by institution of a DNR order during their surgical admission ("new‐DNR" vs. "no‐DNR"), and matched by age (±3 years), frailty score (range: 0–1), and procedure. The main outcome of interest was occurrence of death or hospice transition (DoH) ≤30 postoperative days; this was analyzed using bivariate and multivariable methods. Results: One in 36 older adults had a new‐DNR order. After matching, there were 988 new‐DNR and 988 no‐DNR patients. Median age and frailty score were 82 years and 0.2, respectively. Most underwent orthopedic (47.6%), general (37.6%), and vascular procedures (8.4%). Overall DoH rate ≤30 days was 44.4% for new‐DNR versus 4.0% for no‐DNR patients (p < 0.001). DoH rate for patients who had DNR orders placed in the preoperative, day of surgery, and postoperative setting was 16.7%, 23.3%, and 64.6%, respectively (p < 0.001). In multivariable analysis, compared to no‐DNR patients, those with a new‐DNR order had a 28‐fold higher adjusted odds of DoH (odds ratio [OR] 28.1, 95% confidence interval: 13.0–60.1, p < 0.001); however, odds were 10‐fold lower if the DNR order was placed preoperatively (OR: 5.8, p = 0.003) versus postoperatively (OR: 52.9, p < 0.001). Traditional markers of poor postoperative outcomes such as American Society of Anesthesiologists class and emergency surgery were not independently associated with DoH. Conclusions: An inpatient DNR order was associated with risk of DoH independent of traditional markers of poor surgical outcomes. Further research is needed to understand factors leading to a DNR order that may aid early recognition of high‐risk older adults undergoing surgery. [ABSTRACT FROM AUTHOR]

This study examined the time to initiation of therapeutic plasma exchange (TPE) in pediatric cases of immune thrombotic thrombocytopenic purpura (iTTP). The study found that pediatric patients with iTTP often experience delayed diagnosis, leading to delayed treatment. The mean time to first TPE was over 4 days, indicating delayed treatment. The study suggests that there is a need to improve strategies for early diagnosis and treatment in pediatric iTTP. The study was limited by a low case count and the absence of laboratory data.

This article examines the impact of the Affordable Care Act (ACA) on disparities in pituitary surgery in the United States. The study analyzed data from the National Inpatient Sample over a 7-year period and compared the frequency of pituitary surgeries before and after the implementation of the ACA. The findings suggest that the ACA has had a positive effect on access to pituitary surgery, particularly for underserved populations and those with lower incomes. The expansion of Medicaid and the private insurance exchange were identified as factors contributing to this improvement. The study emphasizes the importance of monitoring data to continue addressing health disparities related to pituitary surgery. [Extracted from the article]

Ocular emergencies comprise 2–3% of emergency department (ED) visits, with retinal detachment requiring emergency surgery. Two-dimensional ultrasound is a rapid bedside tool but is highly operator dependent. We determined three-dimensional ultrasound (3DUS) feasibility, acceptability, and usability in eye pathology detection using the ophthalmologist examination as reference standard. We performed a prospective, blinded cohort study of a 3DUS-enabling device in 30 eye clinic and ED patients with visual symptoms and calculated 3DUS performance characteristics. Two expert readers interpreted the 3DUS images for pathology. All participants completed surveys. 3DUS sensitivity was 0.81, specificity 0.73, positive predictive value 0.54, negative predictive value 0.91, and likelihood ratio (LR)+/LR− 3.03 and 0.26, respectively. Novice and expert sonographers had "substantial" agreement in correct diagnosis of abnormal vs. normal (κ = 0.68, 95% confidence interval 0.48–0.88). Most patients indicated that 3DUS is fast, comfortable, helps them understand their problem, and improves provider interaction/care, and all sonographers agreed; 4/5 sonographers felt confident performing ultrasound. Expert readers correctly identified an abnormal eye in 83/120 scans (76%) and correct diagnosis in 72/120 scans (65%), with no statistical difference between novice (79%; 69%) and expert (72%; 61%) sonographers (p = 0.39, p = 0.55), suggesting reduced operator dependence. Reader diagnosis confidence and image quality varied widely. Image acquisition times were fast for novice (mean 225 ± 83 s) and expert (201 ± 51) sonographers, with fast expert reader interpretation times (225 ± 136). A 3DUS-enabling device demonstrates a sensitivity of 0.81 and specificity of 0.73 for disease detection, fast image acquisition, and may reduce operator dependence for detecting emergent retinal pathologies. Further technological development is needed to improve diagnostic accuracy in identifying and characterizing retinal pathology. [ABSTRACT FROM AUTHOR]

Late-onset Pompe disease (LOPD) is an inherited autosomal recessive progressive metabolic myopathy that presents in the first year of life to adulthood. Clinical presentation is heterogeneous, differential diagnosis is challenging, and diagnostic delay is common. One challenge to differential diagnosis is the overlap of clinical features with those encountered in other forms of acquired/hereditary myopathy. Tongue weakness and imaging abnormalities are increasingly recognized in LOPD. In order to explore the diagnostic potential of tongue involvement in LOPD, we assessed tongue structure and function in 70 subjects, including 10 with LOPD naive to treatment, 30 with other acquired/hereditary myopathy, and 30 controls with neuropathy. Tongue strength was assessed with both manual and quantitative muscle testing. Ultrasound (US) was used to assess tongue overall appearance, echointensity, and thickness. Differences in tongue strength, qualitative appearance, echointensity, and thickness between LOPD subjects and neuropathic controls were statistically significant. Greater tongue involvement was observed in LOPD subjects compared to those with other acquired/hereditary myopathies, based on statistically significant decreases in quantitative tongue strength and sonographic muscle thickness. These findings provide additional evidence for tongue involvement in LOPD characterized by weakness and sonographic abnormalities suggestive of fibrofatty replacement and atrophy. Findings of quantitative tongue weakness and/or atrophy may aid differentiation of LOPD from other acquired/hereditary myopathies. Additionally, our experiences in this study reveal US to be an effective, efficient imaging modality to allow quantitative assessment of the lingual musculature at the point of care.

In heparin-induced thrombocytopenia (HIT), selected patients are treated with therapies directed at the immune response, intravenous immunoglobulin (IVIG) and therapeutic plasma exchange (TPE). To determine IVIG and TPE characteristics and outcomes in HIT, we analyzed the National Inpatient Sample (NIS) database. In a population-based analysis of the NIS, we identified hospital discharges of adult patients with a HIT diagnosis. A two-level statistical analysis was performed comparing cases as follows 1) IVIG or TPE vs. none; and 2) IVIG vs. TPE. For each analysis, the primary outcome was in-hospital mortality. Secondary outcomes were thrombotic events, major bleeding, infections, hospital length of stay, and total charges. Among 22,152 discharges with a HIT diagnosis, 77 (0.34%) and 52 (0.23%) received TPE and IVIG, respectively. In the first level analysis of TPE or IVIG vs. no treatment, TPE or IVIG treatment was associated with a higher likelihood of in-hospital mortality (OR = 1.85; 95%CI: 1.13–3.03, p = 0.0104), major bleeding (OR = 1.91; 95%CI: 1.25–2.93, p = 0.0030), gastrointestinal bleeding (OR = 1.89; 95%CI: 1.08–3.30, p = 0.0259), and infection (OR = 1.65; 95% CI:1.13–2.41, p = 0.0095). In the second-level analysis comparing IVIG vs. TPE, there were no significant differences in patient characteristics or outcomes in both unadjusted and adjusted analyses. In this population-based analysis of HIT, we found similar outcomes of IVIG and TPE-treated cases. Given the small sample size, future studies are needed to confirm this observation. • A population-based study of IVIG and TPE in HIT. • From 2010 to 2014, the prevalence of TPE and IVIG-treated cases was low. • IVIG and TPE-treated cases had similar characteristics and outcomes. • Worse outcomes of IVIG and TPE-treated cases may suggest severe HIT. • Prospective studies are needed to confirm these observations.

Objectives: Patients with undiagnosed obstructive sleep apnea (OSA) often present to an otolaryngologist with symptoms of chronic rhinosinusitis (CRS). This study analyzes symptom profiles of such patients to help identify those who may benefit from polysomnography. Methods: This is a 2-year retrospective analysis of adult patients at an academic practice with a rhinologic chief complaint. Results of the 22-Item Sinonasal Outcomes Test (SNOT-22) were compared between patients with untreated OSA without CRS (OSA group) and a control group of CRS patients (CRS group). Univariate analysis with Bonferroni correction and multiple logistic regression were used. Results: Forty-one patients were included in the OSA group (mean apnea-hypopnea index = 28.8, SD = 21.0) and 124 patients in the CRS group. CRS group demonstrated higher scores in nasal, extra-nasal, and ear/facial symptom domains (P <.001), while OSA group displayed higher psychological (P =.020) and sleep domain scores (P =.048). Nasal discharge (P <.001) and loss of smell/taste (P =.004) scores were higher in CRS group, whereas facial pain (P =.285) and nasal obstruction (P =.822) were not significantly different. On logistic regression, thick nasal discharge, loss of smell/taste, and ear pain were predictive of CRS, while waking up tired was predictive of OSA. Finally, OSA group was more likely to choose a sleep-related issue as a most important symptom (MIS) (P <.001). Conclusions: OSA and CRS have significant overlap in symptom profiles. The SNOT-22 can help identify those with undiagnosed OSA. OSA should be suspected in patients who report a sleep-related item as a MIS and display higher psychological and sleep domain scores.

As medical advances have significantly increased the life expectancy among older adults, the number of older patients requiring trauma care has risen proportionately. Nevertheless, it is unclear among this growing population which sociodemographic and economic factors are associated with decisions to triage and transfer to level I/II centers. This study aims to assess for any association between patient sociodemographic characteristics, triage decisions, and outcomes during acute trauma care presentations. The National Trauma Data Bank was queried for patients aged 65 and older with an injury severity score > 15 between the years 2007 to 2017. Factors associated with subsequent levels of triage on presentation were assessed using multivariate logistic regression, and associations of levels of triage with outcomes of mortality, morbidity, and hospital length of stay are examined using logistic and linear regression models. Triage of 210,310 older adult trauma patients showed significant findings. American Indian patients had higher odds of being transferred to level I/II centers, while Asian, Black, and Native Hawaiian patients had lower odds of being transferred to level I/II centers when compared to Caucasian patients (P < 0.001). Regarding insurance, self-pay (uninsured) patients were less likely to be transferred to a higher level of care; however, this was also demonstrated in private insurance holders (P < 0.001). Caucasian patients had significantly higher odds of mortality, with Black patients (odds ratio [OR] 0.80 [0.75, 0.85]) and American Indian patients (OR 0.87 [0.72, 1.04]) having significantly lower odds (P < 0.001). Compared to government insurance, private insurance holders (OR 0.82 [0.80, 0.85]) also had significantly lower odds of mortality, while higher odds among self-pay were observed (OR 1.75 [1.62, 1.90]), (P < 0.001). Access to insurance is associated with triage decisions involving older adults sustaining trauma, with lower access increasing mortality risk. Factors such as race and gender were less likely to be associated with triage decisions. However, due to this study's retrospective design, further prospective analysis is necessary to fully assess the decisions that influence trauma triage decisions in this patient population.

When immune thrombotic thrombocytopenic purpura (TTP) is suspected, outcomes are impacted by time to therapeutic plasma exchange (TPE). We evaluated the impact of time to TPE on outcomes in suspected TTP cases admitted through the Emergency Department (ED) vs. transferred from another facility (Transfer). In a retrospective analysis of the National Inpatient Sample, we examined the association between TTP outcomes and admission source (ED vs. Transfer) for the primary outcome of time to TPE. A second stratified analyses within each analytic group examined the association of time to TPE (<1 day, 1 day, 2 days, and >2 days) and outcomes for the composite outcome of mortality, major bleeding and thrombosis. Of 1195 cases, 793 (66 %) were admitted through the ED and 402 (34 %) were transferred. Compared to ED cases, Transfers had a longer hospital length of stay (14.69 vs. 16.65 days, p = 0.0060). For ED cases, TPE after >2 days was associated with higher odds of the composite outcome (OR = 1.68 95 % CI: 1.11–2.54; p = 0.0150) and mortality (OR = 3.01 95 % CI: 1.38–6.57; p = 0.0056). For Transfers, TPE on day 2 was associated with higher odds of the composite outcome (OR = 3.00 95 % CI: 1.31–6.89; p = 0.0096) and mortality (OR = 4.95 95 % CI: 1.12–21.88; p = 0.0350). In suspected TTP admitted through the ED or transferred, there was no significant difference in time to TPE. A longer time to TPE was associated with worse outcomes. Future studies should evaluate strategies to decrease initial time to TPE. • A cross sectional analysis of suspected TTP cases presenting to US hospitals • The average time from admission to therapeutic plasma exchange (TPE) was >2 days. • Compared to ED admission, Transfers had a longer hospital length of stay. • Time to TPE >1 day (ED) andr >2 days (Transfers) was associated with worse outcomes.

The addition of plerixafor to high-dose colony-stimulating growth factor has been shown to improve stem cell mobilization rates in autologous transplant patients with multiple myeloma and non-Hodgkin lymphoma. This study evaluates the change in administration time of plerixafor to determine if cell mobilization rates are similar between the US Food and Drug Administration–approved administration time of 11 hours before apheresis and an earlier administration time of 16 hours before apheresis. Medical records of patients age ≥ 18 years undergoing autologous stem cell transplantation requiring the use of plerixafor after at least 4 days of granulocyte colony-stimulating factor therapy to complete stem cell mobilization from January 1, 2010 through September 30, 2014 were retrospectively reviewed. The primary outcome was CD34 + cell mobilization success rates when plerixafor was administered 11 ± 2 hours (standard administration group) compared with 16 ± 2 hours before cell apheresis (early administration group), as defined as collection of  ≥2 × 10 6 CD34 + cells/kg. Secondary outcomes included the number of plerixafor therapy days required to collect a total of ≥2 × 10 6 CD34 + cells/kg, the number of apheresis cycles required to achieve ≥2 × 10 6 CD34 + cells/kg, the median CD34 + cells/kg collected in each apheresis session, and the rates of reported adverse events that occurred in the standard administration time group compared with the early administration time group. Of the 197 patients included, 114 patients received plerixafor 11 ± 2 hours before apheresis and 83 patients received plerixafor 16 hours ± 2 hours before apheresis. Ninety-four percent of patients in the early administration group achieved successful stem cell mobilization compared with 81.6% in the standard administration group ( P  = .0111). The median number of plerixafor days to reach the collection goal of  ≥2 × 10 6 CD34 + cells/kg was 1 day for each group ( P  = .323), and the median number of apheresis days to reach the collection goal was 2 days for the standard administration group compared with 1 day for the early administration group ( P  = .0156). Most adverse events were similar between the 2 groups except for fever, which occurred in 4.8% of the patients in the early administration group and none of the patients in the standard administration group. This study demonstrates plerixafor effectively mobilizes peripheral blood stem cells when given at an early administration time of 16 hours before apheresis compared with standard administration of 11 hours before apheresis. However, further prospective studies could strengthen these results. [ABSTRACT FROM AUTHOR]

Aim Of the Study: While out-of-hospital cardiac arrest (OHCA) is associated with poor survival, early bystander CPR (B-CPR) and telephone CPR (T-CPR) improves survival from OHCA. American Heart Association (AHA) Scientific Statements outline recommendations for T-CPR. We assessed these recommendations and hypothesized that meeting performance standards is associated with increased likelihood of survival. Additional variables were analyzed to identify future performance measurements.Methods: We conducted a retrospective cohort study of non-traumatic, adult, OHCA using the Singapore Pan-Asian Resuscitation Outcomes Study. The primary outcome was likelihood of survival; secondary outcomes were pre-hospital Return of Spontaneous Circulation (ROSC) and B-CPR.Results: From 2012 to 2016, 2,574 arrests met inclusion criteria. Mean age was 68 ± 15; of 2,574, 1,125 (44%) received T-CPR with 5% (135/2574) survival. T-CPR cases that met the Lerner et al. performance metrics analyzed, demonstrated no statistically significant association with survival. Cases which met the Kurz et al. criteria, "Time for Dispatch to Recognize Need for CPR" and "Time to First Compression," had adjusted odds ratios of survival of 1.01 (95% CI:1.00, 1.02; p = <0.01) and 0.99 (95% CI:0.99, 0.99; p = <0.01), respectively. Identified barriers to CPR decreased the odds of T-CPR and B-CPR being performed. Patients with prehospital ROSC had higher odds of B-CPR being performed. EMS response time < 8 minutes was associated with increased survival among patients receiving T-CPR.Conclusion: AHA scientific statements on T-CPR programs serve as ideal starting points for increasing the quality of T-CPR systems and patient outcomes. More work is needed to identify other system performance measures. [ABSTRACT FROM AUTHOR]

Context: Hospices that enroll patients receiving expensive palliative therapies may serve more African Americans because of their greater preferences for aggressive end-of-life care.Objectives: Examine the association between hospices' admission practices and enrollment of African Americans and whites.Methods: This was a cross-sectional study of 61 North and South Carolina hospices. We developed a hospice admission practices scale; higher scores indicate less restrictive practices, that is, greater frequency with which hospices admitted those receiving chemotherapy, inotropes, and so forth. In separate multivariate analyses for each racial group, we examined the relationship between the proportion of decedents (age ≥ 65) served by a hospice in their service area (2008 Medicare Data) and admission practices while controlling for health care resources (e.g., hospital beds) and market concentration in the area, ownership, and budget.Results: Nonprofit hospices and those with larger budgets reported less restrictive admission practices. In bivariate analyses, hospices with less restrictive admission practices served a larger proportion of patients in both racial groups (P < 0.001). However, in the multivariate models, nonprofit ownership and larger budgets but not admission practices predicted the outcome.Conclusion: Hospices with larger budgets served a greater proportion of African Americans and whites in their service area. Although larger hospices reported less restrictive admission practices, they also may have provided other services that may be important to patients regardless of race, such as more in-home support or assistance with nonmedical expenses, and participated in more outreach activities increasing their visibility and referral base. Future research should explore factors that influence decisions about hospice enrollment among racially diverse older adults. [ABSTRACT FROM AUTHOR]

Background: Experts and national organizations recommend that hospices work to increase service to African Americans, a group historically underrepresented in hospice. Objective: The study objective was to describe strategies among hospices in North and South Carolina to increase service to African Americans and identify hospice characteristics associated with these efforts. Methods: The study was a cross-sectional survey using investigator-developed scales to measure frequency of community education/outreach, directed marketing, efforts to recruit African American staff, cultural sensitivity training, and goals to increase service to African Americans. We used nonparametric Wilcoxon tests to compare mean scale scores by sample characteristics. Results: Of 118 eligible hospices, 79 (67%) completed the survey. Over 80% were at least somewhat concerned about the low proportion of African Americans they served, and 78.5% had set goals to increase service to African Americans. Most were engaged in community education/outreach, with 92.4% reporting outreach to churches, 76.0% to social services organizations, 40.5% to businesses, 35.4% to civic groups, and over half to health care providers; 48.0% reported directed marketing via newspaper and 40.5% via radio. The vast majority reported efforts to recruit African American staff, most often registered nurses (63.75%). Nearly 90% offered cultural sensitivity training to staff. The frequency of strategies to increase service to African Americans did not vary by hospice characteristics, such as profit status, size, or vertical integration, but was greater among hospices that had set goals to increase service to African Americans. Conclusions: Many hospices are engaged in efforts to increase service to African Americans. Future research should determine which strategies are most effective. [ABSTRACT FROM AUTHOR]

Objective: An Alzheimer’s disease (AD) diagnosis is preceded by a long period of cognitive decline. We previously demonstrated increased risk of decline among individuals possessing one or more APOE ε4 alleles together with a family history of AD. The objective of this study is to investigate the possibility that such an increased risk might be due to AD risk genes with small effects in combination with APOE. Methods: Participants in the Health and Retirement Study (HRS) over the age of 65, who contributed DNA, and had two or more evaluations with an abbreviated version of the modified Telephone Interview for Cognitive Status (TICS-m) were eligible for the study (n = 7451). A genetic risk score (g-score) was derived using AD risk genes’ meta-analyses data, assigning risk according to the number of risk alleles and summed over all the risk genes. Trajectories of cognitive function were modeled in four groups of Caucasian participants with and without one or more APOE ε4 alleles and either a high or low g-score: APOE ε4-/low g-score; APOE ε4-/high g-score; APOE ε4+/low g-score; and APOE ε4+/high g-score. Post hoc analyses evaluated interactions between individual genes and APOE. Results: Individuals in the APOE ε4+/high g-score group exhibited the greatest cognitive decline over time (p<.0001). This risk appeared to be greater than the sum of the effects of either high g-score or APOE ε4 alone. When gene interactions were individually tested with APOE, a statistically significant interaction with CD33 was discovered (p = 0.04) although the interaction was no longer significant when adjusted for multiple comparisons. Conclusions: Individuals with multiple AD risk genes in addition to having one or more APOE ε4 alleles are at greater risk of cognitive decline than individuals with either APOE ε4 or a high genetic risk score. Among those with one or more APOE ε4 alleles, having one or more copies of the CD33 C (risk) allele may further increase the risk of cognitive decline. [ABSTRACT FROM AUTHOR]

Background: Current Advanced Life Support Termination of Resuscitation (TOR) guidelines suggest when to cease cardiopulmonary resuscitation (CPR). With the significant increase of Dispatch-Assisted CPR (DA-CPR) programs, the impact of DA-CPR on the TOR criteria performance is not clear.Methods: We conducted a secondary analysis of a prospectively collected registry, the Pan-Asian Resuscitation Outcomes Study. We included patients >15 years old with out-of-hospital cardiac arrest between 2014 and 2017 (after implementation of Singapore's DA-CPR program). We excluded patients with non-cardiac etiology, known do-not-resuscitate status, and healthcare provider bystanders. All cases were collected in accordance to Utstein standards. We evaluated the addition of DA-CPR to the diagnostic performance of TOR criteria using logistic regression modeling. The primary outcome was performance for predicting non-survival at 30 days. Sensitivity, specificity, and positive and negative predictive values were calculated.Results: Of the 6009 cases, 319 (5.3%) were still alive at 30 days. Patients had a mean age of 67.9 (standard deviation 15.7) years and were mostly male and Chinese. Almost half of patients had no bystander CPR. The TOR criteria differentiating DA-CPR from unassisted bystander CPR has a specificity of 94% and predictive value of death of 99%, which was not significantly different from undifferentiated CPR criteria. There were differences in adjusted association with survival between unassisted and DA-CPR.Conclusion: Advanced life support TOR criteria retain high specificity and predictive value of death in the context of DA-CPR. Further research should explore the differences between unassisted CPR and DA-CPR to understand differential survival outcomes. [ABSTRACT FROM AUTHOR]

Importance: Mental stress can induce myocardial ischemia and also has been implicated in triggering cardiac events. However, pharmacological interventions aimed at reducing mental stress-induced myocardial ischemia (MSIMI) have not been well studied.Objective: To examine the effects of 6 weeks of escitalopram treatment vs placebo on MSIMI and other psychological stress-related biophysiological and emotional parameters.Design, Setting, and Participants: The REMIT (Responses of Mental Stress Induced Myocardial Ischemia to Escitalopram Treatment) study, a randomized, double-blind, placebo-controlled trial of patients with clinically stable coronary heart disease and laboratory-diagnosed MSIMI. Enrollment occurred from July 24, 2007, through August 24, 2011, at a tertiary medical center.Interventions: Eligible participants were randomized 1:1 to receive escitalopram (dose began at 5 mg/d, with titration to 20 mg/d in 3 weeks) or placebo over 6 weeks.Main Outcomes and Measures: Occurrence of MSIMI, defined as development or worsening of regional wall motion abnormality; left ventricular ejection fraction reduction of 8% or more; and/or horizontal or down-sloping ST-segment depression of 1 mm or more in 2 or more leads, lasting for 3 or more consecutive beats, during 1 or more of 3 mental stressor tasks.Results: Of 127 participants randomized to receive escitalopram (n = 64) or placebo (n = 63), 112 (88.2%) completed end point assessments (n = 56 in each group). At the end of 6 weeks, more patients taking escitalopram (34.2% [95% CI, 25.4%-43.0%]) had absence of MSIMI during the 3 mental stressor tasks compared with patients taking placebo (17.5% [95% CI, 10.4%-24.5%]), based on the unadjusted multiple imputation model for intention-to-treat analysis. A significant difference favoring escitalopram was observed (odds ratio, 2.62 [95% CI, 1.06-6.44]). Rates of exercise-induced ischemia were slightly lower at 6 weeks in the escitalopram group (45.8% [95% CI, 36.6%-55.0%]) than in patients receiving placebo (52.5% [95% CI, 43.3%-61.8%]), but this difference was not statistically significant (adjusted odds ratio; 1.24 [95% CI, 0.60-2.58]; P = .56).Conclusions and Relevance: Among patients with stable coronary heart disease and baseline MSIMI, 6 weeks of escitalopram, compared with placebo, resulted in a lower rate of MSIMI. There was no statistically significant difference in exercise-induced ischemia. Replication of these results in multicenter settings and investigations of other medications for reducing MSIMI are needed.Trial Registration: clinicaltrials.gov Identifier: NCT00574847.

The article describes a study that examined the effects of 6 weeks of escitalopram treatment versus placebo on mental stress-induced myocardial ischemia (MSIMI) and other psychological stress-related biophysiological and emotional parameters. It also states that as part of the study, a randomized clinical trial of patients with clinically stable coronary heart disease and laboratory-diagnosed MSIMI was conducted and also states that patients treated with escitalopram, compared with placebo, resulted in a lower rate of MSIMI. It also states that no statistically significant difference was in exercise-induced ischemia.

Introduction: Venous access for therapeutic plasma exchange (TPE) in myasthenia gravis (MG) can be achieved by central venous catheters (CVC) or peripheral veins (PV), and the preferred method varies among providers. We evaluated our institutional experience with TPE venous access method and complications. Methods: We reviewed all TPE-treated MG patients (2005-2010) through blinded chart review. TPE complications were categorized as serious or minor. Serious complications ended the procedure and/or were potentially life-threatening. Results: A total of 134 MG patients received 230 TPE courses; 56% were outpatient procedures. Whenever feasible, TPE was performed by PV access, which was successful in 75% of courses. Over 90% in both groups improved after TPE. Compared with PV access, CVCs were associated with more total (68% vs. 35%) and serious complications (41% vs. 4%), including 2 deaths. Conclusions: PV access for TPE can be used successfully in most MG patients and may reduce morbidity of the procedure. Muscle Nerve, 2013 [ABSTRACT FROM AUTHOR]

Objectives To examine the characteristics of hospice enrollees with dementia who were discharged alive because their condition stabilized or improved and predictors of death in the year after discharge. Design Cross-sectional analysis of clinical and administrative data. Setting For-profit hospice provider. Participants Hospice enrollees aged 65 and older with an admission diagnosis of dementia who died or were discharged alive because their condition stabilized or improved between January 1, 1999, and December 31, 2003. Measurements Demographic variables and hospice length of stay; data did not include functional status or comorbidities. Results Of 24,111 enrollees with dementia, 1,204 (5.0%) were discharged alive because their condition stabilized or improved; the remainder died while receiving hospice. The median length of stay for those who died was 12 versus 236 days for those discharged alive. Those discharged alive were more likely to be female or have a length of stay exceeding 180 days and less likely to be in the oldest age group (≥85), be African American, or reside in a nursing home. In a subgroup of 303 patients discharged alive, 75.5% were still alive at 1 year; none of the demographic variables were associated with death after hospice discharge. Conclusion A small proportion of hospice enrollees with dementia was discharged alive. Most died shortly after enrollment. Future research should examine other factors that may predict which hospice enrollees with dementia are likely to be discharged alive and their subsequent trajectory, such as functional status, comorbidities, and preferences for care.

Depression is prevalent in patients with heart failure and is associated with a significant increase in hospitalizations and death. Primary results of the Sertraline Against Depression and Heart Disease in Chronic Heart Failure (SADHART-CHF) trial revealed that sertraline and placebo had comparable effects on depression and cardiovascular outcomes. In this study, we explored whether remission from depression was associated with better survival and aimed to characterize participants who remitted during the trial. Based on depression response during the 12-week treatment phase, SADHART-CHF participants were divided into 2 groups: (1) remission, defined as participants whose last measured Hamilton Depression Rating Scale (HDRS) score was <8, and (2) nonremission, defined as participants whose last measured HDRS score was ≥8. Patients who dropped out before having any repeat HDRS were not included. Baseline characteristics and survival differences up to 5 years were evaluated between the remission and nonremission groups. Of the 469 SADHART-CHF participants, 208 (44.3%) achieved remission, 194 (41.4%) remained depressed, and 67 (14.3%) dropped out or died without any repeat HDRS assessment. Patients in the remission group had significantly fewer cardiovascular events than those in the nonremission group (1.34 ± 1.86 vs 1.93 ± 2.71, adjusted p = 0.01). Men patients were more likely to remit than women patients (56.5 vs 44.8%, p = 0.02). The remission group had milder depressive symptoms at baseline compared to the nonremission group (HDRS 17.0 ± 5.4 vs 19.6 ± 5.5, Beck Depression Inventory scale 17.9 ± 6.5 vs 20.3 ± 7.2, p <0.001 for the 2 comparisons). In conclusion, this study indicates that remission from depression may improve the cardiovascular outcome of patients with heart failure. [ABSTRACT FROM AUTHOR]
