Abstract
OBJECTIVE To compare the relative quantity of talk between providers, caregivers, and adolescents and young adults (AYAs) with chronic kidney disease (CKD) and how communication differs by age. METHODS During nephrology clinic visits, conversations between AYAs with CKD (N=99, ages 11-20, median=15), their caregivers, and providers (N=19) were audiotaped and coded using the Roter Interaction Analysis System. Linear mixed models tested AYA age differences in talk frequency by AYAs, caregivers, and providers. Post-hoc analyses tested differences in talk using AYA age groups. RESULTS During clinic visits, providers spoke the most (63.7%), and caregivers spoke more (22.6%) than AYAs (13.7%). Overall talk differed by AYA age in AYAs (p<0.001) and caregivers (p<0.05), but not providers. Higher AYA age was associated with more AYA talk (biomedical information-giving, partnering, rapport-oriented) and less caregiver biomedical information-giving (ps<0.001-0.05). In post-hoc analyses, young adults talked more than adolescents; caregiver talk decreased in the middle-adolescent group. CONCLUSIONS Increases in AYA talk occur primarily in young adulthood, whereas caregiver talk decreases in middle adolescence. This may indicate an appropriate developmental shift but raises concerns about conversational gaps during middle-adolescence. PRACTICE IMPLICATIONS During transition-oriented treatment planning, providers should engage both AYAs and caregivers to avoid potential gaps in communication.

Abstract
Coronary atherosclerotic plaque rupture is the main cause of myocardial infarction and the leading killer in the US. Inflammation is a known bio-marker of plaque vulnerability and can be assessed non-invasively using fluorodeoxyglucose-positron emission tomography imaging (FDG-PET). However, cardiac and respiratory motion of the heart makes PET detection of coronary plaque very challenging. Fat surrounding coronary arteries allows the use of MRI to track plaque motion during simultaneous PET-MR examination. In this study, we proposed and assessed the performance of a fat-MR based coronary motion correction technique for improved FDG-PET coronary plaque imaging in simultaneous PET-MR. The proposed methods were evaluated in a realistic four-dimensional PET-MR simulation study obtained by combining patient water-fat separated MRI and XCAT anthropomorphic phantom. Five small lesions were digitally inserted inside the patients coronary vessels to mimic coronary atherosclerotic plaques. The heart of the XCAT phantom was digitally replaced with the patient's heart. Motion-dependent activity distributions, attenuation maps, and fat-MR volumes of the heart, were generated using the XCAT cardiac and respiratory motion fields. A full Monte Carlo simulation using Siemens mMR's geometry was performed for each motion phase. Cardiac/respiratory motion fields were estimated using non-rigid registration of the transformed fat-MR volumes and incorporated directly into the system matrix of PET reconstruction along with motion-dependent attenuation maps. The proposed motion correction method was compared to conventional PET reconstruction techniques such as no motion correction, cardiac gating, and dual cardiac-respiratory gating. Compared to uncorrected reconstructions, fat-MR based motion compensation yielded an average improvement of plaque-to-background contrast of 29.6%, 43.7%, 57.2%, and 70.6% for true plaque-to-blood ratios of 10, 15, 20 and 25:1, respectively. Channelized Hotelling observer (CHO) signal-to-noise ratio (SNR) was used to quantify plaque detectability. CHO-SNR improvement ranged from 105% to 128% for fat-MR-based motion correction as compared to no motion correction. Likewise, CHO-SNR improvement ranged from 348% to 396% as compared to both cardiac and dual cardiac-respiratory gating approaches. Based on this study, our approach, a fat-MR based motion correction for coronary plaque PET imaging using simultaneous PET-MR, offers great potential for clinical practice. The ultimate performance and limitation of our approach, however, must be fully evaluated in patient studies.

Abstract
Minorities with systemic lupus erythematosus (SLE) are at high risk of poor disease outcomes and may face challenges in effectively self-managing multiple health problems. The Chronic Disease Self-Management Program (CDSMP) is an evidence-based intervention that improves the health of people with chronic illnesses. Although the CDSMP is offered by organizations throughout the United States and many countries around the world, it has not been tested among SLE patients. We pilot tested the benefits of the CDSMP in low-income African American patients with SLE. CDSMP workshops were delivered to 49 African American women with SLE who received medical care at a public lupus clinic in Atlanta, Georgia, US. We compared pre-post CDSMP changes (from baseline to 4 months after the start of the intervention) in health status, self-efficacy and self-management behaviors using self-reported measures. Additionally, we assessed health care utilization changes using electronic administrative records in the 6-month periods before and after the intervention. We observed significant improvements post-intervention in the SF-36 physical health component summary (mean change = 2.4, p = 0.032); self-efficacy (mean change = 0.5, p = 0.035); and several self-management behaviors: cognitive symptoms management (mean change = 0.3, p = 0.036); communication with physicians (mean change = 0.4, p = 0.01); and treatment adherence (mean change = 0.4, p = 0.01). The median number of outpatient visits decreased from 3 to 1 (p < .0001). The CDSMP is a promising intervention for low-income African Americans with SLE. It is an inexpensive program with growing availability around the world that should be further evaluated as a resource to improve patient-centered outcomes and decrease health service utilization among SLE patients.

Abstract
C-reactive protein (CRP), a biomarker of inflammation, has predicted mortality in end-stage respiratory failure and in the critically ill patients. Our aim was to investigate if CRP can predict morbidity and mortality in patients requiring prolonged mechanical ventilation. A prospective study conducted in a ventilator weaning unit of a skilled nursing facility over 13 months included 98 patients older than 18 years of age requiring mechanical ventilation via tracheostomy. Serum CRP and albumin levels were tested on admission. Age, gender, body mass index (BMI), and diagnoses causing respiratory failure were recorded. The outcomes measured were as follows: hospitalization, weaned from mechanical ventilation, and death. Our population had a median age of 77 years and the median BMI, albumin, and mean CRP were 26 kg/m2, 2.25 g/dL, and 5.75 mg/dL, respectively. The most common diseases leading to respiratory failure were pulmonary, neurologic, and cardiac. The patients with the empiric cutoff CRP of <2 mg/dL ( n = 14) had 0% hospitalization rate at 2 weeks and 7% at 30 days, whereas the patients with CRP ≥ 2 mg/dL ( n = 84) had 26% hospitalization rate at 2 weeks and 38% at 30 days. Mortality for the patients with CRP ≥ 2 mg/dL was 26% at 60 days, whereas the CRP < 2 mg/dL patients had no mortality at 60 days ( P = 0.034). The patients who survived 60 days ( n = 70) had significantly lower median CRP levels than the nonsurvivors (4.1 mg/dL vs 8.5 mg/dL, P = 0.009). The area under the receiver operating characteristic (ROC) curve for CRP levels predicting 2-week hospitalization was not large at 0.617 and the optimum CRP cutoff point was >2.7 mg/dL. The sensitivity and negative predictive value of the 2-week hospitalization outcome were equally high at 96%. The area under the ROC curve for 60-day survival was 0.691, and its optimum CRP cutoff point was >3.7 mg/dL with 85% sensitivity and 91% negative predictive value. CRP was not able to predict weaning success in this setting where the 60-day weaning rate was 9%. A CRP level of ≤2.7 mg/dL may be used to screen for patients who are not likely to develop acute illness requiring early 2-week rehospitalization, and a CRP level of ≤3.7 mg/dL may be used to predict 60-day survival in patients with respiratory failure requiring prolonged mechanical ventilation in the long-term care setting.

Abstract
We sought to corroborate geographical differences in hepatitis C virus (HCV) prevalence and assess whether these can be explained by differences in injecting risk behaviour. A community recruited interview survey of 1058 injecting drug users (IDU) - including a blood spot specimen for antibody testing - was undertaken in seven cities in England. HCV prevalence varied from 27% to 74% across sites (chi(2)(6) = 115.3, P < 0.001). There was a significant variation in crack-injection, prison history, injecting frequency, homelessness, groin injecting, syringe reuse and sharing between the sites. Adjustment for clustering by site and other covariates attenuated the odds ratios (OR) for most variables: e.g. crack injection changed from an unadjusted OR of >2 to an adjusted OR of 1.4 (95% CI 0.9-2.0). Remaining significant covariates included: homelessness (OR 2.2; 1.4-3.6); ever imprisonment (OR 1.7; 1.2-2.5); syringe sharing >18 months ago (OR 2.0; 1.3-3.0); injecting duration and age. Introducing site as a second level variable did not reach significance (P = 0.10). HCV prevalence among IDU reporting 'never sharing' was 48%. Geographical variation in HCV prevalence remains poorly explained, but should be the key focus of our surveillance effort. Measures of sharing and their interpretation require greater scrutiny.

Abstract
Information about drug residues and pharmacokinetic parameters in aquatic species is relatively sparse. In addition, it is difficult to rapidly compare data between studies due to differences in experimental conditions, such as water temperatures and salinity. To facilitate the study of aquatic species drug metabolism, we constructed a Fish Drug/Chemical Analysis Phish-Pharm (FDA-PP) database. This database consists of more than 400 articles that include data from 90 species (64 genera) of fish. Data fields include genus, species, water temperatures, the average animal weight, sample types analyzed, drug (or chemical) name, dosage, route of administration, metabolites identified, method of analysis, protein binding, clearance, volume of distribution in a central compartment (Vc) or volume of distribution at steady-state (Vd), and drug half-lives (t((1/2))). Additional fields list the citation, authors, title, and Internet links. The document will be periodically updated, and users are invited to submit additional data. Updates will be announced in future issues of The AAPS Journal. This database will be a valuable resource to investigators of drug metabolism in aquatic species as well as government and private organizations involved in the drug approval process for aquatic species.
