Delayed Newborn First Bath and Exclusive Breastfeeding Rates.

OBJECTIVE: To develop an evidence-based practice project to evaluate the effect of delaying a newborn's first bath on exclusive breastfeeding rates at discharge. DESIGN: A pre- and post-implementation evaluation of the effect of delaying the first bath on exclusive breastfeeding rates at discharge. SETTING: A postpartum unit in a southern California community hospital. PARTICIPANTS: Breastfeeding dyads of women and newborns (>37 weeks gestational age) who were admitted to the postpartum unit. INTERVENTION/MEASUREMENTS: Postpartum nurses involved in the unit practice council, in collaboration with unit leadership, changed the newborn's first bath practice through development of a bathing guideline, nurse education, and mother education. Measurements of the practice change included time of the first bath and exclusive breastfeeding rates at discharge. RESULTS: We observed an increased time for the newborn's first bath from 6.88 hours to 13.71 hours (p ≤ .001). The number of times women chose not to bathe their newborns while in the hospital also increased by approximately seven times, from 0.16% to 1.1%. The rate of exclusive breastfeeding at discharge did not change significantly after implementation (p ≥ .05), regardless of when the first bath was given. CONCLUSION: Delaying a newborn's first bath was not associated with an increase in exclusive breastfeeding rates. More research is needed to determine the effect of bath times.

Implications of the Trauma Quality Improvement Project inclusion of nonsurvivable injuries in performance benchmarking.

BACKGROUND: The Trauma Quality Improvement Project (TQIP) uses an injury prediction model for performance benchmarking. We hypothesize that at a Level I high-volume penetrating trauma center, performance outcomes will be biased due to inclusion of patients with nonsurvivable injuries. METHODS: Retrospective chart review was conducted for all patients included in the institutional TQIP analysis from 2013 to 2014 with length of stay (LOS) less than 1 day to determine survivability of the injuries. Observed (O)/expected (E) mortality ratios were calculated before and after exclusion of these patients. Completeness of data reported to TQIP was examined. RESULTS: Eight hundred twenty-six patients were reported to TQIP including 119 deaths. Nonsurvivable injuries accounted 90.9% of the deaths in patients with an LOS of 1 day or less. The O/E mortality ratio for all patients was 1.061, and the O/E ratio after excluding all patients with LOS less than 1 day found to have nonsurvivable injuries was 0.895. Data for key variables were missing in 63.3% of patients who died in the emergency department, 50% of those taken to the operating room and 0% of those admitted to the intensive care unit. Charts for patients who died with LOS less than 1 day were significantly more likely than those who lived to be missing crucial. CONCLUSION: This study shows TQIP inclusion of patients with nonsurvivable injuries biases outcomes at an urban trauma center. Missing data results in imputation of values, increasing inaccuracy. Further investigation is needed to determine if these findings exist at other institutions, and whether the current TQIP model needs revision to accurately identify and exclude patients with nonsurvivable injuries. LEVEL OF EVIDENCE: Prognostic and epidemiological, level III.

Identification and Investigation of Novel Binding Fragments in the Fatty Acid Binding Protein 6 (FABP6).

Fatty acid binding protein 6 (FABP6) is a potential drug discovery target, which, if inhibited, may have a therapeutic benefit for the treatment of diabetes. Currently, there are no published inhibitors of FABP6, and with the target believed to be amenable to fragment-based drug discovery, a structurally enabled program was initiated. This program successfully identified fragment hits using the surface plasmon resonance (SPR) platform. Several hits were validated with SAR and were found to be displaced by the natural ligand taurocholate. We report the first crystal structure of human FABP6 in the unbound form, in complex with cholate, and with one of the key fragments.

To TQIP or not to TQIP? That is the question.

The Trauma Quality Improvement Program (TQIP) reports a feasible mortality prediction model. We hypothesize that our institutional characteristics differ from TQIP aggregate data, questioning its applicability. We conducted a 2-year (2008 to 2009) retrospective analysis of all trauma activations at a Level 1 trauma center. Data were analyzed using TQIP methodology (three groups: blunt single system, blunt multisystem, and penetrating) to develop a mortality prediction model using multiple logistic regression. These data were compared with TQIP data. Four hundred fifty-seven patients met TQIP inclusion criteria. Penetrating and blunt trauma differed significantly at our institution versus TQIP aggregates (61.9 vs 7.8%; 38.0 vs 92.2%, P < 0.01). There were more firearm mechanisms of injury and less falls compared with TQIP aggregates (28.9 vs 4.2%; 8.5 vs 34.8%, P < 0.01). All other mechanisms were not significantly different. Variables significant in the TQIP model but not found to be predictors of mortality included Glasgow Coma Score motor 2 to 5, systolic blood pressure greater than 90 mmHg, age, initial pulse rate in the emergency department, mechanism of injury, head Abbreviated Injury Score, and abdominal Abbreviated Injury Score. External benchmarking of trauma center performance using mortality prediction models is important in quality improvement for trauma patient care. From our results, TQIP methodology from the pilot study may not be applicable to all institutions.

Orthopaedic nurses' knowledge and interrater reliability of neurovascular assessments with 2-point discrimination test.

PURPOSE: : This study was conducted to evaluate the effects of education on knowledge and interrater reliability of neurovascular assessments with 2-point discrimination (2-PD) test among pediatric orthopaedic nurses. METHODS: : A pre- and posttest study was done among 60 nurses attending 2-hour educational sessions. Neurovascular assessments with 2-PD test were performed on 64 casted pediatric patients by the nurses and 5 nurse experts before and after the educational sessions. RESULTS: : The mean neurovascular assessment knowledge score was improved at posteducation compared with the preeducation (p < .001). The 2-PD test interrater reliability also improved from Cohen's kappa value of 0.24-0.48 at posteducation. CONCLUSIONS: : The 2-hour educational session may be effective in improving nurses' knowledge and the interrater reliability of neurovascular assessment with 2-PD test.

Autologous mesenchymal stem cells produce reverse remodelling in chronic ischaemic cardiomyopathy.

AIMS: The ability of mesenchymal stem cells (MSCs) to heal the chronically injured heart remains controversial. Here we tested the hypothesis that autologous MSCs can be safely injected into a chronic myocardial infarct scar, reduce its size, and improve ventricular function. METHODS AND RESULTS: Female adult Göttingen swine (n = 15) underwent left anterior descending coronary artery balloon occlusion to create reproducible ischaemia-reperfusion infarctions. Bone-marrow-derived MSCs were isolated and expanded from each animal. Twelve weeks post-myocardial infarction (MI), animals were randomized to receive surgical injection of either phosphate buffered saline (placebo, n = 6), 20 million (low dose, n = 3), or 200 million (high dose, n = 6) autologous MSCs in the infarct and border zone. Injections were administered to the beating heart via left anterior thoracotomy. Serial cardiac magnetic resonance imaging was performed to evaluate infarct size, myocardial blood flow (MBF), and left ventricular (LV) function. There was no difference in mortality, post-injection arrhythmias, cardiac enzyme release, or systemic inflammatory markers between groups. Whereas MI size remained constant in placebo and exhibited a trend towards reduction in low dose, high-dose MSC therapy reduced infarct size from 18.2 +/- 0.9 to 14.4 +/- 1.0% (P = 0.02) of LV mass. In addition, both low and high-dose treatments increased regional contractility and MBF in both infarct and border zones. Ectopic tissue formation was not observed with MSCs. CONCLUSION: Together these data demonstrate that autologous MSCs can be safely delivered in an adult heart failure model, producing substantial structural and functional reverse remodelling. These findings demonstrate the safety and efficacy of autologous MSC therapy and support clinical trials of MSC therapy in patients with chronic ischaemic cardiomyopathy.
