Profiles of Serial Changes in Cardiac Troponin T Concentrations and Outcome in Ambulatory Patients With Chronic Heart Failure
ObjectivesThe purpose of this study was to determine whether different profiles of cardiac troponin T (cTnT) values assessed over time would yield incremental prognostic information on clinically stable outpatients with heart failure (HF).BackgroundcTnT levels were used to estimate prognosis in HF; however, most studies evaluated hospitalized patients using single measurements.MethodsA cohort of 172 New York Heart Association functional class III to IV outpatients was prospectively studied with serial cTnT measurements collected every 3 months over a 2-year period. The primary end point was death or cardiac transplantation, and secondary end points included HF hospitalization.ResultsOf the 172 patients, 22 (13%) died or underwent transplantation during the first year. Therefore, 150 patients were included in the second-year analysis of 3 pre-determined groups: 1) no serial cTnT elevations (defined as <0.01 ng/ml); 2) 1 or more, but not all cTnT values elevated ≥0.01 ng/ml; and 3) all cTnT values elevated during the first year. During the second year, 30 events occurred: 53 patients had persistently normal cTnT levels (<0.01 ng/ml) with 6 primary events (11%); 57 patients had 1 or more but not all cTnT levels elevated with 11 events (19%); 40 patients demonstrated persistently elevated cTnT levels with 13 (33%) primary events (odds ratio: 3.77; 95% confidence interval: 1.28 to 11.07, p = 0.02).ConclusionsElevations in cTnT, even using a low threshold of 0.01 ng/ml, detected during routine clinical follow-up of ambulatory patients with HF, are highly associated with an increased risk of events, particularly with frequent or persistent cTnT elevations of ≥0.01 ng/ml. Therefore, the ability to monitor clinical change through serial cTnT measurements may add to risk assessment in the ambulatory HF population
Case Study of a Comprehensive Team-Based Approach to Increase Colorectal Cancer Screening
Introduction: Colorectal cancer is the second leading cause of cancer deaths among men and women in West Virginia. In addition, 51% of all colorectal cancers diagnosed in West Virginia from 2012 to 2016 were detected at either regional (31%) or distant (20%) stages indicating a need for improved early detection.
Methods: West Virginia University Cheat Lake Physicians participated in the West Virginia Program to Increase Colorectal Cancer Screening, a program of Cancer Prevention and Control at the WVU Cancer Institute. As a result, Cheat Lake Physicians assembled a team of health care professionals to implement evidence-based interventions and system changes including provider assessment and feedback, patient reminders, accurate data capture, and tracking of CRC screening tests.
Results: These efforts resulted in a 15.8% increase in colorectal cancer screening rates within one year of implementation. Additionally, the clinic achieved a 66% return rate for Fecal Immunochemical Test kits, an inexpensive, stool-based colorectal cancer screening test.
Implications: The utilization of a team-based approach to patient care yields positive results that can be carried over to other cancer and disease prevention efforts in primary care clinics
A prospective analysis describing the innovative use of liposomal bupivacaine in burn patients
Burn patients frequently require autograft harvesting to facilitate wound healing, often resulting in significant pain. Liposomal bupivacaine is indicated for administration into a surgical site to produce postsurgical analgesia. The objective of this study was to evaluate efficacy, safety, and duration of postoperative analgesia with liposomal bupivacaine for donor site pain in burn patients. This was an observational, case–control study including adult patients with <20% total body surface area (TBSA) burned who received liposomal bupivacaine for postoperative pain management after autograft harvesting from lower extremity donor site(s). Patients from the case group were matched to historical control patients treated with traditional pain management. The primary outcome was the cumulative pain scores on postoperative day one measured by the area under the curve (AUC0–24). Secondary outcomes included AUC0–72, total milligram morphine equivalents (MME), length of stay, and adverse events. Data were collected in 36 patients who received liposomal bupivacaine, with 21 patients eligible for matching to historical controls. Patients included in the intervention and control groups were well-matched at baseline. Patients in the intervention group had a significantly lower median (IQR) AUC0–24 [578 (408,740) vs. 680 (544,803); p = 0.05] and shorter length of stay [4 days (1,9.5) vs. 6 days (318); p = 0.01]. No differences in adverse events related to the administration of liposomal bupivacaine or opioid-related adverse events were observed. Results indicate liposomal bupivacaine is safe and effective in burn patients. The results of this study add to the limited body of literature examining efficacy in this population

Family Outcomes After the Pediatric Intensive Care Unit: A Scoping Review
Background: Intensivists are increasingly attuned to the post-discharge outcomes experienced by families because patient recovery and family outcomes are interdependent after childhood critical illness. In this scoping review of international contemporary literature, we describe the evidence of family effects and functioning post-PICU as well as outcome measures used in order to identify strengths and weaknesses in the literature.Methods: We reviewed all articles published between 1970 and 2017 in PubMed, EMBASE, PsycINFO, Cumulative Index of Nursing and Allied Health Literature (CINAHL), or the Cochrane Controlled Trials Registry. Our search used a combination of terms for the concept of “critical care/illness” combined with additional terms for the pre-specified domains of social, cognitive, emotional, physical, health-related quality of life (HRQL), and family functioning.Results: We identified 71 articles reporting on the post-PICU experience of more than 2,400 parents and 3,600 families of PICU survivors in 8 countries. These articles used 101 different metrics to assess the various aspects of family outcomes; 34 articles also included open-ended interviews. Overall, most families experienced significant disruption in at least 5 out of 6 of our family outcomes subdomains, with themes of decline in mental health, physical health, family cohesion, and family finances identified. Almost all articles represented relatively small, single-center or disease-specific observational studies. There was disproportionate representation of families of higher socioeconomic status and Caucasian race, and there was much more data about mothers compared to fathers. There was also very limited information regarding outcomes for siblings and extended family members after a child’s PICU stay. Conclusions: Significant opportunities remain for research exploring family functioning after PICU discharge. We recommend that future work include more diverse populations with respect to the critically ill child as well as family characteristics, include more intervention studies, and enrich existing knowledge about outcomes for siblings and extended family
Dietary Oxidative Balance Scores and Biomarkers of Inflammation among Individuals with and without Chronic Kidney Disease
Background: Oxidative stress and inflammation are proposed mechanisms of nonspecific kidney injury and progressive kidney failure. Higher dietary oxidative balance scores (OBS) are associated with lower prevalence of chronic kidney disease (CKD). Methods: We investigated the association between OBS and biomarkers of inflammation using data from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study. Nutrient estimates from the Block Food Frequency Questionnaires were used to define tertiles of 11 pro- and antioxidant factors. Points for each OBS component were summed, with a higher score indicating predominance of antioxidant exposures. Multivariable linear regression models were used to estimate the association between OBS and biomarkers of inflammation (interleukin-6 [IL-6], interleukin-8 [IL-8], interleukin-10 [IL-10], fibrinogen, C-reactive protein [CRP], white blood cell count, and cystatin C). An interaction term was included to determine if associations between OBS and inflammatory markers differed between individuals with and without CKD. Results: Of 682 participants, 22.4% had CKD. In adjusted models, OBS was associated with CRP and IL-6. For every 5-unit increase in OBS, the CRP concentration was –15.3% lower (95% CI: –25.6, –3.6). The association of OBS with IL-6 differed by CKD status; for every 5-unit increase in OBS, IL-6 was –10.7% lower (95% CI: –16.3, –4.7) among those without CKD, but there was no association among those with CKD (p = 0.03). Conclusion: This study suggests that a higher OBS is associated with more favorable levels of IL-6 and CRP, and that the association of OBS and IL-6 may be modified by CKD status

Investigation of the Strontium-90 Contaminant Plume along the Shoreline of the Columbia River at the 100-N Area of the Hanford Site
Efforts are underway to remediate strontium-laden groundwater to the Columbia River at the 100-N Area of the Hanford Site. Past practices of the 100-N reactor liquid waste disposal sites has left strontium-90 sorbed onto sediments which is a continuing source of contaminant discharge to the river. The Remediation Task of the Science and Technology Project assessed the interaction of groundwater and river water at the hyporheic zone. Limited data have been obtained at this interface of contaminant concentrations, geology, groundwater chemistry, affects of river stage and other variables that may affect strontium-90 release. Efforts were also undertaken to determine the extent, both laterally and horizontally, of the strontium-90 plume along the shoreline and to potentially find an alternative constituent to monitor strontium-90 that would be more cost effective and could possibly be done under real time conditions. A baseline of strontium-90 concentrations along the shoreline was developed to help assess remediation technologies
