The Evolution of Physical Activity and Health Research in China: A Bibliometric Analysis of Study Areas and Sex Balance in Authorship.

BACKGROUND: This article evaluates the evolution of physical activity and health research in China through a bibliometric analysis focused on number of publications, study areas, and sex balance in authorship. METHODS: A systematic review was conducted by the Global Observatory for Physical Activity for "physical activity and health" publications between 1950 and 2019. Here, we focus on the 610 Chinese publications identified, defined as those in which data collection took place in China. We assessed the number of publications, classified them into 5 areas (1) surveillance, (2) correlates and determinants, (3) health consequences, (4) interventions, and (5) policy, and analyzed female participation in authorship. RESULTS: The first Chinese publication identified in the review was in 1990. Since, the average number of physical activity and health publications increased from one per year in the 1990s to 7.6 per year in the 2000s, and to 47 per year in the 2010s. Most publications focused on the correlates and determinants (38.7%) and the health consequences of physical activity (35.9%). Physical activity policy accounted for 2.3% of the publications. In the 1990s, 64% of the publications included at least one female author; this proportion increased to 90% in the 2010s. CONCLUSION: Despite a slow start, China's research on physical activity and health has grown rapidly since 2000. The distribution of publications by study areas and female participation in authorship is similar to that observed globally, with fewer publications focused on interventions and policy as compared with other topics.

Central-line-associated bloodstream infections and central-line-associated non-CLABSI complications among pediatric oncology patients.

OBJECTIVE: To assess central venous catheter (CVC) harm in pediatric oncology patients, we explored risks for central-line-associated bloodstream infections (CLABSIs) and central-line-associated non-CLABSI complications (CLANCs). DESIGN: Retrospective cohort study. SETTING: Midwestern US pediatric oncology program. PATIENTS: The study cohort comprised 592 pediatric oncology patients seen between 2006 and 2016. METHODS: CLABSIs were defined according to Centers for Disease Control and Prevention (CDC)/National Health Safety Network (NHSN) definitions. CLANCs were classified using a novel definition requiring CVC removal. Patient-level and central-line-level risks were calculated using a negative binomial model to adjust for correlations between total events and line numbers. RESULTS: CVCs were inserted in 62% of patients, with 175,937 total catheter days. The inpatient CLABSI and CLANC rates were 5.8 and 8.5 times higher than outpatient rates. At the patient level, shared risks included acute myeloid leukemia (AML) and age <1 year at diagnosis. At the line level, shared risks included age <1 year at diagnosis, non-mediports, and >1 lumen. AML was a CLABSI-specific risk. CLANC-specific risks included non-brain-tumor diagnosis, younger age at diagnosis or central-line placement, and age <1 year at diagnosis or line placement. Multivariable risks were for CLABSI >1 lumen and for CLANC age <1 year at placement. CONCLUSIONS: Among patients with CVCs, CLABSI and CLANC rates were similar, higher among inpatients than outpatients. For both CLABSIs and CLANCs, infants and patients with AML were at higher risk. In both univariate and multivariate models, lines with >1 lumen were associated with CLABSIs and placement during infancy with CLANCs.

Children from socioeconomically disadvantaged communities present in more advanced heart failure at the time of transplant listing.

Transplant registries in the US do not collect information about community level risk factors. We utilized a community level socio-economic risk indicator, the distressed communities' index to understand its association with clinical presentation among children listed for heart transplant (HT). We found that currently, majority (40%) of children listed from distressed communities are Black. On multivariable analysis, compared to children from prosperous communities, those from distressed communities listed for HT were significantly more likely to be Status 1A (adjusted odds ratio [aOR] 1.39) and on a ventricular assist device (aOR 1.44). Compared to White children from prosperous communities, both Black and White children from distressed communities were more likely to be listed Status 1A (aOR 2.1 and 1.36 respectively) and have renal dysfunction (aOR 1.71 and 1.52 respectively). In conclusion, heart failure severity at listing appears more likely associated with community-level risk factors and less so with child's race/ethnicity.

Nitrogen dioxide, an EPA parameter, may forecast the incidence of asthma exacerbations across urban areas: An observational study.

RATIONALE: Efforts to reduce nitrogen dioxide (NO2 ) have the potential to reduce the morbidity and mortality related to asthma in children. We analyze the associations of pediatric hospital admission rates for asthma with Environmental Protection Agency (EPA) NO2  parameters at the patient zip code level. METHODS: We identified zip codes that had EPA monitors which monitored NO2  levels located in states with high asthma burden. We used the Healthcare Cost and Utilization Project (HCUP) State Inpatient Database (SID) to identify patients who were <17 years of age with diagnosis codes for asthma. We compared NO2  levels at the zip code level with the number of patients hospitalized for asthma from the HCUP SID database. RESULTS: Data from zip codes in Buffalo, Detroit, Phoenix, and Tucson from 2009 to 2011 demonstrated that the monthly mean NO2  levels predicted pediatric asthma hospital admission rates in six monitored zip codes in these four cities with time series modeling (Buffalo zip code 14206, p = 0.0089; Detroit zip code 48205, p = 0.0179; Phoenix zip code 85006, p = 0.0433; Phoenix zip code 85009, p = 0.0007; Phoenix zip code 85015, p = 0.0036; Tucson zip code 85711, p = 0.0004). CONCLUSION: Pediatric admissions to the hospital for asthma exacerbations mirror the cyclic and seasonal pattern of NO2  levels in the cities of Detroit, Buffalo, Phoenix, and Tucson. While traffic density may be higher in cities with periodicity of NO2  and asthma exacerbations, other factors could be contributing to high NO2  levels.

Place-based heterogeneity in lung transplant recipient outcomes.

Place is defined as a social or environmental area of residence with meaning to a patient. We hypothesize there is an association between place and the clinical outcomes of lung transplant recipients in the United States. In a retrospective cohort study of transplants between January 1, 2010, and December 31, 2019, in the Scientific Registry of Transplant Recipients, multivariable Cox regression models were used to test the association between place (through social and environmental factors) with readmission, lung rejection, and survival. Among 18,465 recipients, only 20% resided in the same county as the transplant center. Recipients from the most socially vulnerable counties when compared to the least vulnerable were more likely to have COPD as a native disease, Black or African American race, and travel long distances to reach a transplant center. Higher local life expectancy was associated with lower likelihood for readmission (odds ratio [OR] = 0.90, 95% confidence interval [CI]: 0.84, 0.98, p = .01). Higher social vulnerability was associated with a higher likelihood of lung rejection (OR = 1.37, [CI]: 1.07, 1.76, p = .01). There was no association of residence with posttransplant survival. Recipient place-based factors were associated with complications and processes of care after transplant and warrant further investigation.

Preoperative assessment using the five-factor modified frailty index: A call for standardized preoperative assessment and prehabilitation services in gynecologic oncology.

OBJECTIVE: To evaluate if the 5-factor modified frailty index (mFI) is associated with postoperative complications, readmissions or non-home discharge in gynecologic cancer patients undergoing surgery. METHODS: Patients with a diagnosis of gynecologic cancer (cervical, uterine, or ovarian cancer) who underwent surgery between 2014 and 2018 were identified through the National Surgical Quality Improvement Program (NSQIP) database. The 5-factor mFI was applied and patients classified into 6 categories (mFI groups 0,1,2, 3, 4 and 5). The incidence of 30-day complications, readmissions and non-home discharge was evaluated. Multivariable logistic regression models were used to determine the association between mFI category and readmissions/ complications. Adjusted probabilities of events were calculated based on patient characteristics. RESULTS: At total of 31,181 gynecologic cancer cases were included in the analysis: N = 2968 (9.4%) cervical, N = 20,862 (66.4%) uterine, and N = 7351 (23.4%) ovarian cancers. Of all patients, 46.1% were in category 0, 36.5% category 1, and 1% category 3-5. Factors associated with increased mFI included older age, African American race, laparoscopic surgery and obesity. A significant dose-response relationship between higher mFI and readmission and 30-day complications was noted on adjusted multivariable analysis (adjusted OR 2.37 (1.65-3.45) and 2.10 (1.59-2.75) for readmissions and complications, respectively, in mFI category 3-5). These associations were consistent within each cancer type. CONCLUSIONS: The 5-factor mFI universally predicts postoperative readmissions, 30-day complications and non-home discharge in patients with gynecologic cancer. Incorporation of mFI into routine preoperative assessment can identify patients for non-surgical treatments, prehabiliatation and short term home assessments.

Vascular Risk Factor Prevalence and Trends in Native Americans with Ischemic Stroke.

INTRODUCTION: Native Americans have a higher incidence and prevalence of stroke and the highest stroke-related mortality among race-ethnic groups in the United States. We aimed to analyze trends in the ischemic stroke (IS) vascular risk factor prevalence in Native Americans along with a comparison to the other race-ethnic groups. METHODS: National Inpatient Sample (NIS) database was used to explore the prevalence of risk factors among hospitalized IS patients during 2000 - 2016. Prevalence estimates were calculated for each risk factor within each race-ethnic group in 6 time periods. Linear trends were explored using linear regression models, with differences in trends between the Native American group and the other race-ethnic groups assessed using interaction terms. The analysis accounted for the complex sampling design, including hospital clusters, NIS stratum, and trend weights for analyzing multiple years of NIS data. RESULTS: Native Americans constituted 5472 of the 1,278,784 IS patients. The age-and-sex-standardized prevalence of hypertension (slope = 2.24, p < 0.001), hyperlipidemia (slope = 6.29, p < 0.001), diabetes (slope = 2.04, p = 0.005), atrial fibrillation/flutter (trend slope = 0.80, p = 0.011), heart failure (trend slope = 0.73, p = 0.036) smoking (trend slope= 3.65, p < 0.001), and alcohol (slope = 0.60, p = 0.019) increased among Native Americans. They showed larger increases in hypertension prevalence compared to Blacks, Hispanics, and Asian/Pacific Islanders and in smoking prevalence compared to Hispanics and Asian/Pacific Islanders. By the year 2015-2016, Native Americans had the highest overall prevalence of diabetes, coronary artery disease, smoking, and alcohol among all race-ethnic groups. CONCLUSION: The prevalence of most vascular risk factors among ischemic stroke patients has increased in Native Americans over the last two decades. Significantly larger increases in hypertension and smoking prevalence were seen in Native Americans compared to other groups along with them having the highest prevalence in multiple risk factors in recent years.

The Association of Socioeconomic Status and Discharge Destination with 30-Day Readmission after Ischemic Stroke.

OBJECTIVES: This study aimed to explore the association of socioeconomic status and discharge destination with 30-day readmission after ischemic stroke. MATERIALS AND METHODS: We examined 30-day all-cause readmission among patients hospitalized for ischemic stroke in states of Arkansas, Iowa, and Wisconsin in 2016 and 2017 and New York in 2016 using Healthcare Cost and Utilization Project (HCUP) State Inpatient Databases. RESULTS: Among the 52301 patients included, 51.1% were female. The 30-day readmission rates were 10.2%, 8.2%, 9.3%, 10.4%, 11.6%, and 11.2% for age group 18-34, 35-44, 45-54, 55-64, 65-74, and ≥75 years, respectively (p<0.001). In Generalized Estimating Equation analysis, patients with Medicare and Medicaid insurance were more likely to be readmitted, compared with private insurance, (adjusted Odds Ratio [aOR] 1.37, 95% CI 1.23-1.53; and aOR 1.26, 95% CI 1.09-1.45, respectively). Patients in the bottom quartile of zip code level median household income had higher 30-day readmission rate (12.4%) than those in the 2nd, 3rd and 4th quartile (10.3%, 10.1%, and 10.7%, respectively, p<0.001). Compared with those discharged home with self-care which had the lowest readmission rate (8.4%), patients who left against medical advice had the highest readmission rate (18.6%; aOR 2.23, 95% CI 1.75-2.83), followed by rehabilitation and skilled nursing facilities (13.2%; aOR 1.33, 95% CI 1.22-1.46), and home with home health care (11.3%, aOR 1.18, 95% CI 1.08-1.28). CONCLUSIONS: Socioeconomic status and discharged destination affect readmission after stroke. These results provide evidence to inform vulnerable patient population as targets for readmission prevention.

"Living Well with Chronic Pain": Integrative Pain Management via Shared Medical Appointments.

OBJECTIVE: To evaluate the effectiveness of a multidisciplinary, nonpharmacological, integrative approach that uses shared medical appointments to improve health-related quality of life and reduce opioid medication use in patients with chronic pain. DESIGN: This is a retrospective, pre-post review of "Living Well with Chronic Pain" shared medical appointments (August 2016 through May 2018). SETTING: The appointments included eight 3-hour-long visits held once per week at an outpatient wellness facility. SUBJECTS: Patients with chronic, non-cancer-related pain. METHODS: Patients received evaluation and evidence-based therapies from a team of integrative and lifestyle medicine professionals, as well as education about nonpharmacological therapeutic approaches, the etiology of pain, and the relationship of pain to lifestyle factors. Experiential elements focused on the relaxation techniques of meditation, yoga, breathing, and hypnotherapy, while patients also received acupuncture, acupressure, massage, cognitive behavioral therapy, and chiropractic education. Patients self-reported data via the Patient-Reported Outcomes Measurement Information System (PROMIS-57) standardized questionnaire. Use of opioid medications was evaluated in morphine milligram equivalents. RESULTS: A total of 178 participants completed the PROMIS-57 questionnaire at the first and the last visits. Statistically significant improvements in all domains (Physical Functioning, Anxiety, Depression, Fatigue, Social Roles, Pain Interference, and Sleep Disturbance) were observed (P < 0.001) between the pre-intervention (visit 1) and post-intervention (visit 8) scores. Average opioid use decreased nonsignificantly over the 8-week intervention, but the lower rate of opioid use was not sustained at 6 and 12 months' follow-up. CONCLUSIONS: Patients suffering from chronic pain who participated in a multidisciplinary, nonpharmacological treatment approach delivered via shared medical appointments experienced reduced pain and improved measures of physical, mental, and social health without increased use of opioid pain medications.

Mediterranean diet adherence and metabolic syndrome in US adolescents.

The Mediterranean diet (MD) has been found to lower the risk of heart disease, stroke, and diabetes in adults. Little is known about its acceptance and relationship to cardiovascular risk markers in US adolescents. Using data from the National Health and Nutrition Examination Survey, years 2007-2014, we performed a cross-sectional analysis of adherence to the Mediterranean diet among a representative sample of US adolescents (n = 4223), factors that influence adherence, and whether adherence is associated with cardiometabolic risk factors including metabolic syndrome. MD adherence was calculated using the KIDMED scoring system. We found that overall MD adherence was very low among US adolescents, with Mexican American youths having higher adherence compared to other groups. Higher income was associated with greater adherence. There was low intake of key MD foods including olive oil and finfish. The unadjusted prevalence of metabolic syndrome was 6.6%. MD adherence was not associated with metabolic syndrome.

The Patterns and Outcomes of Inter-Hospital Transfer Among Medicare Patients with Ischemic Stroke.

BACKGROUND AND PURPOSE: Inter-hospital transfer for ischemic stroke is an essential part of stroke system of care. This study aimed to understand the national patterns and outcomes of ischemic stroke transfer. METHODS AND RESULTS: This retrospective study examined Medicare beneficiaries aged ≥65 years undergoing inter-hospital transfer for ischemic stroke in 2012. Cox proportional hazards model was used to compare 30-day and one-year mortality between transferred patients and direct admissions from the emergency department (ED admissions). Among 312,367 ischemic stroke admissions, 5.7% underwent inter-hospital transfer. Using this value as cut-off, the hospitals were classified into receiving (n = 411), sending (n = 559), and low-transfer (n = 1863) hospitals. Receiving hospitals were larger than low-transfer and sending hospitals as demonstrated by the median bed number (371, 189, and 88, respectively, p < 0.001); more frequently to be certified stroke centers (75%, 47%, and 16%, respectively, p < 0.001); and less commonly located in the rural area (2%, 7%, and 24%, respectively, p < 0.001). For receiving hospitals, transfer-in patients and ED admissions had comparable mortality at 30 days (10% vs 10%; adjusted HR [aHR]=1.07; 95% CI, 0.99-1.14) and 1 year (23% vs 24%; aHR=1.03; 95% CI, 0.99-1.08). For sending hospitals, transfer-out patients, compared to ED admissions, had higher mortality at 30 days (14% vs 11%; aHR=1.63; 95% CI, 1.39-1.91) and 1 year (30% vs 27%; aHR=1.33; 95% CI, 1.20-1.48). For low-transfer hospitals, overall transfer-in and transfer-out patients, compared to ED admissions, had higher mortality at 30 days (13% vs 10%; aHR=1.46; 95% CI, 1.33-1.60) and 1 year (28% vs 25%; aHR=1.27; 95% CI, 1.19-1.36). CONCLUSIONS: Hospitals in the US, based on their transfer patterns, could be classified into 3 groups that shared distinct characteristics including hospital size, rural vs urban location, and stroke certification. Transferred patients at sending and low-transfer hospitals had worse outcomes than their ED admission counterpart.

Automated External Defibrillator Application Before EMS Arrival in Pediatric Cardiac Arrests.

BACKGROUND: Little is known about the predictors of pre-emergency medical service (EMS) automated external defibrillator (AED) application in pediatric out-of-hospital cardiac arrests. We sought to determine patient- and neighborhood-level characteristics associated with pre-EMS AED application in the pediatric population. METHODS: We reviewed prospectively collected data from the Cardiac Arrest Registry to Enhance Survival on pediatric patients (age >1 to ≤18 years old) who had out-of-hospital nontraumatic arrest (2013-2015). RESULTS: A total of 1398 patients were included in this analysis (64% boys, 45% white, and median age of 11 years old). An AED was applied in 28% of the cases. Factors associated with pre-EMS AED application in univariable analyses were older age (odds ratio [OR]: 1.9; 12-18 years old vs 2-11 years old; P < .001), white versus African American race (OR: 1.4; P = .04), public location (OR: 1.9; P < .001), witnessed status (OR: 1.6; P < .001), arrests presumed to be cardiac versus respiratory etiology (OR: 1.5; P = .02) or drowning etiology (OR: 2.0; P < .001), white-populated neighborhoods (OR: 1.2 per 20% increase in white race; P = .01), neighborhood median household income (OR: 1.1 per $20 000 increase; P = .02), and neighborhood level of education (OR: 1.3 per 20% increase in high school graduates; P = .006). However, only age, witnessed status, arrest location, and arrests of presumed cardiac etiology versus drowning remained significant in the multivariable model. The overall cohort survival to hospital discharge was 19%. CONCLUSIONS: The overall pre-EMS AED application rate in pediatric patients remains low.

Value of, Attitudes Toward, and Implementation of Evidence-Based Practices Based on Use of Self-Study Learning Modules.

BACKGROUND: It is unknown if completing educational modules on understanding, reviewing, and synthesizing research literature is associated with higher value of, attitudes toward, and implementation of evidence-based practices. METHOD: Nurses completed valid, reliable questionnaires on the value of, attitudes toward, and implementation of evidence-based practice 6 months after four educational modules were introduced. Multivariable modeling was used to learn associations of education modules and evidence-based practice themes. RESULTS: Of 1,033 participants, 54% completed at least one education module; 22% completed all modules. Value and attitude about evidence-based practice were moderately high, but implementation was low (mean = 15.15 ± 15.72; range = 0 to 72). After controlling for nurse characteristics and experiences associated with evidence-based practice value, attitudes, and implementation scores, education modules completion was associated with the implementation of evidence-based practice (p = .001), but not with value or attitude of evidence-based practices scores. CONCLUSION: Education on reviewing and synthesizing literature strengthened implementation of evidence-based practices. J Contin Educ Nurs. 2017;48(5):209-216.

Choroid plexus tumors in adult and pediatric populations: the Cleveland Clinic and University Hospitals experience.

Choroid plexus tumors (CPT) are rare neoplasms accounting for 1-4% of all pediatric brain tumors. They are divided into choroid plexus papilloma (CPP), atypical choroid plexus papilloma (APP) and choroid plexus carcinoma (CPC). CPTs are known to primarily affect children less than 2 years of age. Gross total resection is the most important predictor of survival especially in CPC. Although small case series have been published, limited clinical data are available to describe treatment and outcome of CPTs. More clinical data would be necessary to complete the picture, particularly in populations that are not age limited. Here we share data from the two major hospitals in Cleveland to describe treatment and outcome of adult and pediatric patients. We performed a retrospective analysis of patients with CPT seen in Cleveland Clinic from 1990 to 2015 and at University Hospitals from 1994 to 2015. Results were compared to previously published historical controls. We identified 30 cases with CPT, including 22 pediatric and eight adult cases; 11 females and 19 males. The mean age at presentation was 12.4 years with a median age of 4.5 years (range 2 months-51 years). Gross total surgical resection was achieved in 22, subtotal resection in four, partial resection in two and unknown in two. The histology was CPP in 23 patients, two of whom developed recurrence requiring repeat resection and adjuvant therapy. Median event free survival (EFS) for CPP patients was 7.6 years. The histology was CPC in seven patients. All CPC patients were treated with adjuvant therapy. Median EFS of CPC patients was 4.4 years. Overall survival of all CPT patients was 100% with a median follow up of 7 years. A systematic literature review identified 1012 CPT patients treated from 1989 to 2013. The mean and median age of CPT patients was 13 and 3 years respectively. The median survival of 541 CPP patients was undefined vs. 2.7 years for the 452 CPC patients. The difference between the two populations was highly significant (p < 0.001). Kaplan-Meier survival curves comparing CPTs at Cleveland Clinic and University Hospitals versus a systematic literature review showed a statistically significant advancement in overall survival among the patients treated at Cleveland Clinic and University Hospitals. Our data are consistent with the literature review regarding epidemiology, clinical presentation, and treatment modalities but differed in regards to survival. Differences in survival may be related to different methods of data collection or details in patient care.

Magnitude of Anemia at Discharge Increases 30-Day Hospital Readmissions.

BACKGROUND: Anemia during hospitalization is associated with poor health outcomes. Does anemia at discharge place patients at risk for hospital readmission within 30 days of discharge? Our objectives were to examine the prevalence and magnitude of anemia at hospital discharge and determine whether anemia at discharge was associated with 30-day readmissions among a cohort of hospitalizations in a single health care system. METHODS: From January 1, 2009, to August 31, 2011, there were 152,757 eligible hospitalizations within a single health care system. The endpoint was any hospitalization within 30 days of discharge. The University HealthSystem Consortium's clinical database was used for demographics and comorbidities; hemoglobin values are from the hospitals' electronic medical records, and readmission status was obtained from the University HealthSystem Consortium administrative data systems. Mild anemia was defined as hemoglobin of greater than 11 to less than 12 g/dl in women and greater than 11 to less than 13 g/dl in men; moderate, greater than 9 to less than or equal to 11 g/dl; and severe, less than or equal to 9 g/dl. Logistic regression was used to assess the association of anemia and 30-day readmissions adjusted for demographics, comorbidity, and hospitalization type. RESULTS: Among 152,757 hospitalizations, 72% of patients were discharged with anemia: 31,903 (21%), mild; 52,971 (35%), moderate; and 25,522 (17%), severe. Discharge anemia was associated with severity-dependent increased odds for 30-day hospital readmission compared with those without anemia: for mild anemia, 1.74 (1.65-1.82); moderate anemia, 2.76 (2.64-2.89); and severe anemia, 3.47 (3.30-3.65), P < 0.001. CONCLUSIONS: Anemia at discharge is associated with a severity-dependent increased risk for 30-day readmission. A strategy focusing on anemia treatment care paths during index hospitalization offers an opportunity to influence subsequent readmissions.

From Bad to Worse: Anemia on Admission and Hospital-Acquired Anemia.

BACKGROUND: Anemia at hospitalization is often treated as an accompaniment to an underlying illness, without active investigation, despite its association with morbidity. Development of hospital-acquired anemia (HAA) has also been associated with increased risk for poor outcomes. Together, they may further heighten morbidity risk from bad to worse. OBJECTIVES: The aims of this study were to (1) examine mortality, length of stay, and total charges in patients with present-on-admission (POA) anemia and (2) determine whether these are exacerbated by development of HAA. DESIGN/SETTING/PATIENTS: In this cohort investigation, from January 1, 2009, to August 31, 2011, a total of 44,483 patients with POA anemia were admitted to a single health system compared with a reference group of 48,640 without POA anemia or HAA. MEASUREMENTS: Data sources included the University HealthSystem Consortium database and electronic medical records. Risk-adjustment methods included logistic and linear regression models for mortality, length of stay, and total charges. Present-on-admission anemia was defined by administrative coding. Hospital-acquired anemia was determined by changes in hemoglobin values from the electronic medical record. RESULTS: Approximately one-half of the patients experienced worsening of anemia with development of HAA. Risk for death and resource use increased with increasing severity of HAA. Those who developed severe HAA had 2-fold greater odds for death; that is, mild POA anemia with development of severe HAA resulted in greater mortality (odds ratio, 2.57; 95% confidence interval, 2.08-3.18; P < 0.001), increased length of stay (2.23; 2.16-2.31; P < 0.001), and higher charges (2.09; 2.03-2.15; P < 0.001). CONCLUSIONS: Present-on-admission anemia is associated with increased mortality and resource use. This risk is further increased from bad to worse when patients develop HAA. Efforts to address POA anemia and HAA deserve attention.

Effectiveness of Shared Medical Appointments Versus Traditional Clinic Visits for Adolescents With Type 1 Diabetes.

Shared medical appointments began in the United States in 1996 to advance quality of care and enhance patients' ability to self-manage. Group visits gather patients with the same diagnosis for individual examinations followed by group education sessions taught by the provider. This leads to the opportunity to learn from the experiences of others. The Cleveland Clinic Department of Pediatric Endocrinology offers a shared medical appointment group for pediatric patients with type 1 diabetes called the ESCALAIT clinic (Enrichment Services and Care for Adolescents Living with Autoimmune Insulin Dependent Type 1 Diabetes). The objective of this study was to compare the effectiveness of traditional clinic visits with shared medical appointments for adolescents with type 1 diabetes in terms of hemoglobin A1c (HbA1c) improvement. Eighty ESCALAIT patients, aged 11 to 19 years were compared with 516 clinic controls of the same age. Visits were approximately 3 months apart for both patient groups. Changes in HbA1c between groups were calculated from the first to fourth visits. There was a statistically significant difference between the ESCALAIT clinic patients and the control patients. Our results revealed that the group visit patients had less improvement in HbA1c values at the last visit approximately 1 year later, but we would argue that the difference is not clinically significant. However, there were many benefits to shared medical appointment visits including increased access to care as well as peer support. Shared medical appointments are therefore a valid alternative to traditional clinic visits in this patient population.

Double-blind, placebo-controlled, proof-of-concept trial of bexarotene Xin moderate Alzheimer's disease.

BACKGROUND: We assessed the impact of retinoid X receptor (RXR) agonist bexarotene on brain amyloid measured by amyloid imaging in patients with Alzheimer's disease (AD) in a proof-of-concept trial. METHODS: Twenty patients with AD [Mini Mental State Examination (MMSE) score 10-20 inclusive] with positive florbetapir scans were randomized to receive 300 mg of bexarotene or placebo for 4 weeks. The amyloid imaging result was the primary outcome. Whole-population analyses and prespecified analyses by genotype [apolipoprotein E ε4 (ApoE4) carriers and ApoE4 noncarriers] were conducted. Secondary outcomes included scores on the Alzheimer's Disease Assessment Scale-Cognitive subscale, Alzheimer's Disease Cooperative Study-Activities of Daily Living scale, MMSE, Clinical Dementia Rating scale, and Neuropsychiatric Inventory. Serum amyloid-ß (Aß) peptide sequences Aß1-40 and Aß1-42 measurements were collected as biomarker outcomes. RESULTS: There was no change in the composite or regional amyloid burden when all patients were included in the analysis. ApoE4 noncarriers showed a significant reduction in brain amyloid on the composite measure in five of six regional measurements. No change in amyloid burden was observed in ApoE4 carriers. There was a significant association between increased serum Aß1-42 and reductions in brain amyloid in ApoE4 noncarriers (not in carriers). There were significant elevations in serum triglycerides in bexarotene-treated patients. There was no consistent change in any clinical measure. CONCLUSIONS: The primary outcome of this trial was negative. The data suggest that bexarotene reduced brain amyloid and increased serum Aß1-42 in ApoE4 noncarriers. Elevated triglycerides could represent a cardiovascular risk, and bexarotene should not be administered outside a research setting. RXR agonists warrant further investigations as AD therapies.
