A bedside ultrasound sign of cardiac disease: the left atrium-to-aorta diastolic diameter ratio.

PURPOSE: This study evaluated a simple ultrasound method to detect left atrial (LA) enlargement by comparing the diameters of the LA and aortic root. PROCEDURES: The LA and aortic diameters, the LA volume index (LAVI), and significant echo findings were analyzed in 101 consecutive echocardiograms. Mean LAVI and the prevalence of an abnormal echo were compared between groups in which the ratio of the LA diameter to aortic diameter in diastole was >1 vs < or = 1. FINDINGS: Left atrial-to-aortic diameter ratio increased with LAVI (r = 0.64, P < .001). Left atrial-to-aortic diameter ratio >1 vs < or = 1 was noted in 45% vs 55% of patients and had a mean (+ or - SD) LAVI = 39 + or - 12 vs 27 + or - 7 mL/m(2) (P < .001) and a 78% vs 43% prevalence of an abnormal echo (P < .001). CONCLUSION: The left atrium-to-aorta diastolic diameter ratio can detect LA enlargement and may be useful as a quick bedside technique to screen for cardiac disease.

Combatting Homelessness in Canada: Applying Lessons Learned from Six Tiny Villages to the Edmonton Bridge Healing Program.

Emerging evidence shows that homelessness continues to be a chronic public health problem throughout Canada. The Bridge Healing Program has been proposed in Edmonton, Alberta, as a novel approach to combat homelessness by using hospital emergency departments (ED) as a gateway to temporary housing. Building on the ideas of Tiny Villages, the Bridge Healing Program provides residents with immediate temporary housing before transitioning them to permanent homes. This paper aims to understand effective strategies that underlie the Tiny Villages concept by analyzing six case studies and applying the lessons learned to improving the Bridge Healing Program. After looking at six Tiny Villages, we identified four common elements of many successful Tiny Villages. These include a strong community, public support, funding with few restrictions, and affordable housing options post-graduation. The Bridge Healing Program emphasizes such key elements by having a strong team, numerous services, and connections to permanent housing. Furthermore, the Bridge Healing Program is unique in its ability to reduce repeat ED visits, lengths of stay in the ED, and healthcare costs. Overall, the Bridge Healing Program exhibits many traits associated with successful Tiny Villages and has the potential to address a gap in our current healthcare system.

Opportunities for nurses to support recovery after pediatric injury: Relationships among posttraumatic stress, hope, and quality of life.

PURPOSE: Nurses are at the forefront of children's postinjury recovery; this unique role provides an opportunity for nurses to recognize and screen for symptoms that may interfere with children's quality of life (QOL). As such, aims of the present investigation were to explore selected variables (e.g., posttraumatic stress symptoms [PTSS], hope) that have the potential to impact QOL after pediatric injury, with a larger goal of contributing to recommendations for nursing practice to support children's full (physical and emotional) recovery during the peritrauma period following injury. DESIGN AND METHODS: Sixty children (aged 7-13) completed measures of PTSS, hope, and QOL while receiving injury treatment. RESULTS: PTSS significantly predicted concurrent QOL, ß = -0.42, p = 0.001. Exploratory results demonstrated that specific PTSS clusters (re-experiencing [ ß = -0.39; p = 0.003), avoidance [ ß = -0.35; p = 0.009], arousal [ ß = -0.34; p = .012]) all significantly predicted QOL. Specific PTSS were explored. Hope (overall, domains of pathways, general agency, goal setting) did not significantly predict concurrent QOL. PRACTICE IMPLICATIONS: While this study is exploratory and more research is needed, current results suggest that nurses' awareness of PTSS (including symptoms of re-experiencing, avoidance, arousal) may help medical teams in identifying children that are at risk for impaired functional recovery (e.g., QOL) during the peritrauma period. Nurses may want to consider advocating for the integration of PTSS screeners into standard medical care. In addition, nurses have the opportunity to serve as key medical professionals in the delivery of trauma-informed medical care (which aims to minimize further trauma or re-traumatization). Nursing leadership may want to consider offering training in how nurses can identify and respond to children who have experienced an injury (such as trauma-informed care).

Let's Talk About It: Supporting Family Communication during End-of-Life Care of Pediatric Patients.

BACKGROUND: Communication is key in optimizing medical care when a child is approaching end of life (EOL). Research is yet to establish best practices for how medical teams can guide intrafamily communication (including surviving siblings) when EOL care is underway or anticipated for a pediatric patient. While recommendations regarding how medical teams can facilitate communication between the medical team and the family exist, various barriers may prevent the implementation of these recommendations. OBJECTIVE: This review aims to provide a summary of research-to-date on family and medical provider perceptions of communication during pediatric EOL care. DESIGN: Systematic review. RESULTS: Findings from a review of 65 studies suggest that when a child enters EOL care, many parents try to protect their child and/or themselves by avoiding discussions about death. Despite current recommendations, medical teams often refrain from discussing EOL care with pediatric patients until death is imminent for a variety of reasons (e.g., family factors and discomfort with EOL conversations). Parents consistently report a need for honest complete information, delivered with sensitivity. Pediatric patients often report a preference to be informed of their prognosis, and siblings express a desire to be involved in EOL discussions. CONCLUSIONS: Families may benefit from enhanced communication around EOL planning, both within the family and between the family and medical team. Future research should investigate a potential role for medical teams in supporting intrafamily communication about EOL challenges and should examine how communication between medical teams and families can be facilitated as EOL approaches.

The use of B-type natriuretic peptide to assess volume status in patients with end-stage renal disease.

BACKGROUND: Although B-type natriuretic peptide (BNP) levels correlate with volume overload in congestive heart failure, its usefulness in patients with renal dysfunction has been questioned. A simple test to estimate volume overload and assist in the management of dry weight in hemodialysis (HD) patients would be useful. METHODS: Thirty-nine patients--aged 64 +/- 2 years (mean +/- SEM), male-female ratio of 37:2--undergoing HD thrice weekly for at least 30 days were studied. Samples were collected at the start and end of each of 3 consecutive HD sessions. Pre- and postsession weights and blood pressures were recorded. Left ventricular ejection fractions were obtained from echocardiograms performed within 1 year of enrollment. The first session was the dialysis session after a 72-hour interdialytic period, whereas the second and third sessions were after a 48-hour period. Plasma volume changes were measured in a subset of 13 patients. RESULTS: Pre- and postdialysis BNP levels for each of the 3 sessions were 434 and 343 pg/mL, 347 and 231 pg/mL, and 249 and 202 pg/mL, respectively. The values for body weights were 82.6 +/- 3.6 and 78.6 +/- 3.5 kg, 81.5 +/- 3.6 and 78.2 +/- 3.5 kg, and 81.5 +/- 3.46 and 78.3 +/- 3.5 kg, respectively. The values of mean systolic blood pressures were 150 +/- 4 and 134 +/- 3 mm Hg, 142 +/- 4 and 134 +/- 4 mm Hg, and 142 +/- 4 and 131 +/- 4 mm Hg, respectively. The values for mean diastolic blood pressures were 81 +/- 2.5 and 70 +/- 2.4 mm Hg, 74 +/- 2.4 and 72.1 +/- 2.2 mm Hg, and 76 +/- 2.9 and 72 +/- 2.9 mm Hg, respectively. There was no correlation between changes in intradialytic BNP values and other measured parameters. Plasma volume changed minimally during dialysis. CONCLUSIONS: Values of BNP are elevated in patients with end-stage renal disease and decline after each dialysis session. Over the course of a week, BNP levels gradually declined irrespective of changes in weight or blood pressure. The lack of correlation between changes in BNP and changes in measured clinical parameters is partly explained by a lack of a significant change in plasma volume. The highest BNP values were seen in patients with systolic dysfunction.

Disrupting the transmission of influenza a: face masks and ultraviolet light as control measures.

In the event of an influenza pandemic, where effective vaccine and antiviral drugs may be lacking, disrupting environmental transmission of the influenza virus will be the only viable strategy to protect the public. We discuss 2 such modalities, respirators (face masks) and ultraviolet (UV) light. Largely overlooked, the potential utility of each is underappreciated. The effectiveness of disposable face masks may be increased by sealing the edges of the mask to the face. Reusable masks should be stockpiled, because the supply of disposable masks will likely prove inadequate. UV light, directed overhead, may be beneficial in hospitals and nursing homes.

Spinal cord infarct caused from suspected fibrocartilaginous embolism.

INTRODUCTION: We report a case of spinal cord infarct as a result of suspected fibrocartilaginous embolism (FCE). CASE PRESENTATION: A 23-year-old man presented with sudden onset cervical and upper back pain followed by progressive weakness in his extremities after throwing a baseball. History, neurologic examination and spinal cord imaging were consistent with spinal cord infarct. We believe the cause was from FCE. DISCUSSION: Though rare, physicians should be familiar with this diagnosis and the proposed mechanisms. There is no specific treatment for FCE-related spinal cord infarct and long-term prognosis is largely dependent on the degree of spinal cord injury.

Application of a Framework to Implement Trauma-Informed Care Throughout a Pediatric Health Care Network.

INTRODUCTION: To evaluate the initial application of a recently published three-step framework for implementing trauma-informed care (TIC) in a pediatric health care network by applying Framework for Spread. METHODS: In steps 1 and 2 of the framework, we established commitment from the health care network leadership and initial interest in TIC among clinical providers (step 1), set evidence-based training goals and created the associated TIC training content (step 2). In step 3, 440 health care professionals (from 27 health care teams) participated in single-session, 1-hour training that covered the psychological impact of injury- and illness-related trauma, identification of traumatic stress symptoms, and how to respond to children exposed to potentially traumatic events. A concomitant quality improvement project allowed us to assess potential changes in training participants' favorable attitudes toward the integration of TIC and confidence in delivering TIC. RESULTS: Compared with pretraining, participants demonstrated increases in attitude toward TIC, t(293) = 5.8, P < .001, Cohen's d = 0.32, and confidence in delivering TIC, t(293) = 20.9, P < .001, Cohen's d = 1.09. DISCUSSION: Trainings were effective in achieving proximal goals targeting attitudes and confidence, thereby demonstrating the feasibility and clinical relevance of TIC training when implemented according to the three-step framework. Future research should examine methods of training to reach wide audiences to promote systematic change and evaluate changes in patient outcomes associated with providers' implementation of TIC.

An initial application of a biopsychosocial framework to predict posttraumatic stress following pediatric injury.

OBJECTIVE: Each year millions of children suffer from unintentional injuries that result in poor emotional and physical health. This study examined selected biopsychosocial factors (i.e., child heart rate, peritrauma appraisals, early coping, trauma history) to elucidate their roles in promoting emotional recovery following injury. The study evaluated specific hypotheses that threat appraisals (global and trauma-specific) and coping would predict subsequent posttraumatic stress symptoms (PTSS), that coping would mediate the association between early and later PTSS, and that heart rate would predict PTSS and appraisals would mediate this association. METHOD: Participants were 96 children hospitalized for injury and assessed at 3 time points: T1 (within 2 weeks of injury), T2 (6-week follow-up), and T3 (12-week follow-up). Participants completed measures of trauma history and appraisals at T1, coping at T2, and PTSS at T1, T2, and T3. Heart rate was abstracted from medical records. Structural equation modeling was employed to evaluate study hypotheses. RESULTS: Heart rate was not associated with PTSS or appraisals. Models including trauma history, appraisals, coping, and PTSS were constructed to test other study hypotheses and fit the data well. T1 global and trauma-specific threat appraisals were associated with T1 PTSS; T2 avoidant coping was a significant mediator of the relation between T1 and T3 PTSS. CONCLUSION: Findings confirm a role for appraisals and coping in the development of PTSS over the weeks following pediatric injury. Early appraisals and avoidant coping may be appropriate targets for prevention and early intervention. Future researchers should further explicate the utility of a biopsychosocial framework in predicting PTSS. (PsycINFO Database Record

Ectopic acromegaly due to a pancreatic neuroendocrine tumor producing growth hormone-releasing hormone.

OBJECTIVE: To present a case of acromegaly due to ectopic growth hormone-releasing hormone (GHRH) secretion from a pancreatic neuroendocrine tumor in the context of multiple endocrine neoplasia type 1 (MEN 1). METHODS: We describe the clinical, imaging, and pathologic findings of the study patient. RESULTS: A 46-year-old woman presented with clinical and biochemical findings diagnostic of acromegaly. Magnetic resonance imaging showed a 1.2-cm sellar mass. Following resection of the macroadenoma, serum insulin-like growth factor 1 (IGF-1) and growth hormone (GH) levels remained unchanged. Pathologic examination revealed adenomatous changes, including a nonsecretory focus and a prolactin immunopositive area (GH stain negative in both). Octreotide long-acting release was ineffective. Search for an ectopic tumor included normal octreoscan and abdominal computed tomography. GHRH was greater than 1000 pg/mL. Repeated abdominal computed tomography documented a 6.2-cm mass in the tail and body of the pancreas. Distal pancreatectomy revealed a pancreatic neuroendocrine tumor that stained positive for GHRH. Postoperatively, serum GHRH and IGF-1 normalized. Re-evaluation of the initial pituitary pathologic specimen revealed additional somatotroph hyperplasia of the adjacent, normal pituitary gland. Primary hyperparathyroidism was diagnosed, and multigland parathyroid hyperplasia was noted at surgery. Genetic testing was positive for a mutation in the MEN1 gene. CONCLUSION: This patient's acromegaly was resistant to somatostatin analogue therapy, reflecting the negative octreoscan imaging. In addition, this case is novel because the patient presented with pituitary adenomatous changes, which were presumably associated with MEN 1 and/or possibly the elevated GHRH levels.
