Despite the widespread use of combination antiretroviral therapy (cART), HIV-associated neurocognitive impairment (NCI) remains a health concern. However, limited research has been done to identify factors associated with neurocognitive decline. We assessed risk factors associated with neurocognitive decline in people living with HIV using a definition of decline that is statistically easy to adopt, is based on a commonly used neuropsychological cut-off and may be clinically relevant. Cox proportional hazards modeling was performed using the CNS HIV Antiretroviral Therapy Effects Research (CHARTER) study database. 581 participants were followed for up to 12 years. Neurocognitive decline was defined as the first observed drop in global T-scores of at least 2.67. Lifetime methamphetamine use had the strongest association with neurocognitive decline (adjusted Hazard Ratio; aHR = 1.48; 95% CI = 0.92–2.39) followed by no current antiretroviral medication use (aHR = 1.32; 95% CI = 0.91–1.92). Other risk factors included Hispanic ethnicity, lifetime history of major depressive disorder, lifetime cannabis use, hepatitis-C infection, and difficulty eating, dressing, bathing, or using the toilet. Results indicate that consistent use of ART may be of high significance to preserving neurocognition. Furthermore, Hispanic patients, those with a history of depression and substance use, and those having difficulty in essential activities of daily living may require vigilant follow-up.

BackgroundThe club cell secretory protein (CC16) has anti-inflammatory and antioxidant effects, and low CC16 serum levels have been associated with both risk and progression of COPD, yet the interaction between smoking and CC16 on lung function outcomes remains unknown.MethodsUtilizing cross-sectional data on United States veterans, CC16 serum concentrations were measured by ELISA and log transformed for analyses. Spirometry was conducted and COPD status was defined by post-bronchodilator FEV1/FVC ratio ResultsThe study population (N = 351) was mostly male, white, with an average age over 60 years. An interaction between CC16 and smoking status on FEV1/FVC ratio was demonstrated among subjects with COPD (N = 245, p = 0.01). There was a positive correlation among former smokers and negative correlation among current or never smokers with COPD. Among former smokers with COPD, CC16 levels were also positively correlated with years since smoking cessation, and inversely related with pack-years smoked. Increasing CC16 levels were associated with lower odds of COPD (ORadj = 0.36, 95% CI 0.22–0.57, Padj ConclusionsSmoking status is an important effect modifier of CC16 relationships with lung function. Increasing serum CC16 corresponded to increases in FEV1/FVC ratio in former smokers with COPD versus opposite relationships in current or never smokers. Additional longitudinal studies may be warranted to assess relationship of CC16 with smoking cessation on lung function among subjects with COPD.

Personal protective equipment used by healthcare workers to mitigate disease transmission risks while caring for patients with high-consequence infectious diseases can impair normal body cooling mechanisms and exacerbate physiological strain. Symptoms of heat strain (e.g., cognitive impairment, confusion, muscle cramping) are especially harmful in the high-risk environment of high-consequence infectious disease care. In this pilot study, the core body temperatures of healthcare workers were assessed using an ingestible, wireless-transmission thermometer while performing patient care tasks common to a high-level isolation unit setting in powered air purifying respirator (PAPR)-level. The objective was to determine the potential for occupational health hazard due to heat stress in an environmentally controlled unit. Maximum core temperatures of the six participants ranged from 37.4 °C (99.3 °F) to 39.9 °C (103.8

Background Heart failure (HF) is a multifaceted syndrome that requires self-management for adherence to treatment to control symptoms. Symptoms need to be monitored to prevent impending HF exacerbations. Few HF study authors have assessed efficacy of mobile health (mHealth) interventions particularly with virtual visits to evaluate outcomes such as symptoms and healthcare utilization. Objective The aim of this pilot study was to evaluate the potential effect of mHealth self-management interventions on symptom status and health-related quality of life and describe health care utilization in patients with HF. Methods This 3-month pilot study included 74 patients with HF and used a randomized 3-group repeated-measures design (enhanced usual care, mHealth, and mHealth plus [+] virtual visits). Surveys included the Heart Failure Symptom Survey, EuroQol, and a specialized phone application for patients to report weights and medications. Results The mHealth groups had an overall decrease in most symptom severity and frequency, particularly shortness of breath. Compared to enhanced usual care, both the mHealth+ and mHealth groups showed promise with medium effect sizes (range .55-.60) in relation to shortness of breath and a medium effect (.51) for lower extremity edema for the mHealth+ group. There was a trend toward improvement in health-related quality of life in both intervention groups at month 3. The mHealth+ group had fewer rehospitalizations. Conclusions In general, both mHealth groups fared better on symptoms and health care utilization. Small to medium effect sizes on selected symptom outcomes warrant this study to be conducted in a fully powered study. Virtual visits may assist in symptom recognition and self-management.

Objective Comparative analyses of survival and funding statistics in cancers with high mortality were performed to quantify discrepancies and identify areas for intervention. Background Discrepancies in research funding may contribute to stagnant survival rates in pancreatic ductal adenocarcinoma (PDAC). Methods The Surveillance, Epidemiology, and End Results database was queried for survival statistics. Funding data were obtained from the National Cancer Institute (NCI). Clinical trial data were obtained from www.clinicaltrials.gov. Cancers with high mortality were included for analyses. Results Since 1997, PDAC has received lesser funding ($1.41 billion) than other cancers such as breast ($10.52 billion), prostate ($4.93 billion), lung ($4.80 billion), and colorectal ($4.50 billion). Similarly, fewer clinical trials have been completed in PDAC (n = 608) compared with breast (n = 1904), lung (n = 1629), colorectal (n = 1080), and prostate (n = 1055) cancer. Despite this, since 1997, dollars invested in PDAC research produced a greater return on investment with regards to 5-year overall survival (5Y-OS) compared with breast, prostate, uterine, and ovarian cancer. Incremental cost-effectiveness analysis demonstrates that millions (liver, non-Hodgkin lymphoma, and melanoma) and billions (colorectal and lung) of dollars were required for each additional 1% increase in 5Y-OS compared with PDAC. Funding of research towards early diagnosis of PDAC has decreased by 19% since 2007. For nearly all cancers, treatment-related research receives the highest percentage of NCI funding. Conclusions Funding of PDAC research is significantly less than other cancers, despite its higher mortality and greater potential to improve 5Y-OS. Increased awareness and lobbying are required to increase funding, promote research, and improve survival.

Background: We used the Therapy Preference Scale, a 30-item questionnaire, to determine cancer treatment preferences of adults with cancer. Methods: We used Wilcoxon’s rank sum test and Fisher’s exact test to compare the preferences of younger (

Background: Several family-based efficacious pediatric weight management interventions (PWMIs) have been developed to reduce child weight status. These programs are typically based in larger cities...

ObjectiveThe role of aromatherapy in supportive symptom management for pediatric patients receiving palliative care has been underexplored. This pilot study aimed to measure the impact of aromatherapy using validated child-reported nausea, pain, and mood scales 5 minutes and 60 minutes after aromatherapy exposure.MethodsThe 3 intervention arms included use of a symptom-specific aromatherapy sachet scent involving deep breathing. The parallel default control arm (for those children with medical exclusion criteria to aromatherapy) included use of a visual imagery picture envelope and deep breathing. Symptom burden was sequentially assessed at 5 and 60 minutes using the Baxter Retching Faces scale for nausea, the Wong-Baker FACES scale for pain, and the Children's Anxiety and Pain Scale (CAPS) for anxious mood. Ninety children or adolescents (mean age 9.4 years) at a free-standing children's hospital in the United States were included in each arm (total n = 180).ResultsAt 5 minutes, there was a mean improvement of 3/10 (standard deviation [SD] 2.21) on the nausea scale; 2.6/10 (SD 1.83) on the pain scale; and 1.6/5 (SD 0.93) on the mood scale for the aromatherapy cohort (p< 0.0001). Symptom burden remained improved at 60 minutes post-intervention (Significance of resultsAromatherapy represents an implementable supportive care intervention for pediatric patients receiving palliative care consults for symptom burden. The high number of children disqualified from the aromatherapy arm because of pulmonary or allergy indications warrants further attention to outcomes for additional breathing-based integrative modalities.

BACKGROUND: Respiratory therapists (RTs) are care providers in highly stressful work environments with limited time and resources for self-care. Mindfulness-based interventions teach non-reactive awareness to the present situation or the ability to respond versus react in the moment, to shift away from a physical and emotional stress response. METHODS: Mindfulness-based group learning was offered during 2 regularly scheduled RT staff meetings for ∼30 min each session. Each meeting began and concluded with a distress assessment and with counting and recording respirations for 30 s. RESULTS: This quality-improvement project revealed mindfulness-based interventions to be feasible and acceptable. Mindfulness intervention reduced RT team members9 physical and emotional stress related symptoms (as measured by a 1-point median decrease in the self-administered distress assessment, with P = .001 in session 1) and increased sense of calm (as measured by participant breathing rate decrease by mean of two-points P = .001 in session 1 and session 2). CONCLUSIONS: Mindfulness-based interventions were noted to be feasible and acceptable additions to RT staff meetings. These interventions have the potential to introduce breathing practices and mini mindfulness techniques.

Implementation of pediatric palliative care as a primary practice relevant for all pediatricians and pediatric subspecialists requires a grounding, shared knowledge. This study reports on the innovative application of a monthly Palliative Care E-Journal Club (Pal Care Club) to foster shared palliative care knowledge hospital wide.To explore the impact of a monthly electronic journal club to increase the number of palliative care-relevant articles read and discussed and to enhance provider comfort with the integration and introduction of palliative care.A single cohort, predesign-post-design was utilized to explore the impact of a monthly palliative care electronic journal club.Preintervention barriers to reading pediatric palliative care literature were primarily access and time. The mean of paired differences (post-pre) for the number of full-text articles read per month was 2.56 (SD = 1.25). The journal club intervention increased participant personal comfort with integrating palliative care principles at the bedside (p 0.0001) and introducing pediatric palliative care to patients and families (p 0.0001).An electronic journal club is a feasible and acceptable means of increasing number of palliative care articles read and discussed across an institution as well as enhancing pediatric palliative care knowledge across subspecialist and general pediatric services.

Purpose: Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy demonstrating aberrant and progressive expression of mucins. The contribution of individual mucins has been extensively investigated in PDAC; however, comprehensive mucin profiling including splice variants in PDAC tumors has not been reported. Experimental Design: Using publicly available RNA sequencing (RNA-seq) datasets, we assess the expression of mucin family members and their splice variants (SV) in PDAC tumor samples for the first time. Mucin SVs that are correlated with PDAC patient survival are validated in a cohort of patient tumor samples. Further, we use computational methods to derive novel pancreatic tumor subtypes using mucin expression signatures and their associated activated pathways. Results: Principal component analysis identified four novel mucin-based PDAC subtypes. Pathway analysis implicated specific biological signatures for each subtype, labeled (i) immune activated, (ii) progressive, (iii) pancreatitis-initiated, and (iv) anti-inflammatory/PanIN-initiated. Assessing mucin SVs, significantly longer survival is observed with higher expression of 4 MUC1 and 1 MUC13 SVs, whereas patients expressing 2 MUC4 and 1 MUC16 SVs had shorter survival. Using a whole-transcriptome correlation, a three-gene panel, including ESRP2, PTK6, and MAGEH1, is designated to assess PDAC tumor sample cellularity by PCR. One MUC4 SV and one MUC13 SV are quantified in a separate PDAC patient cohort, and their effects on survival are experimentally validated. Conclusions: Altogether, we demonstrate the unique expression pattern of mucins, four mucin-based PDAC subtypes, and the contribution of MUC1, MUC4, and MUC16 SVs in PDAC patient survival.

HIV-related neurocognitive impairment (NCI) may increase the risk of death. However, a survival disadvantage for patients with NCI has not been well studied in the post-combination antiretroviral therapy (cART) era. Specifically, limited research has been conducted considering the reversible nature and variable progression of the impairment and this area demands further evaluation. We performed multivariable Cox proportional hazards modeling to assess the association between baseline NCI (global T scores) and mortality. A joint modeling approach was then used to model the trajectory of global neurocognitive functioning over time and the association between neurocognitive trajectory and mortality. Among the National NeuroAIDS Tissue Consortium’s (NNTC) HIV-infected participants, we found a strong negative association between NCI and mortality in the older age groups (e.g., at age = 55, HR = 0.79; 95% CI 0.64–0.99). Three neurocognitive sub-domains (abstraction and executive functioning, speed of information processing, and motor) had the strongest negative association with mortality. Joint modelling indicated a 33% lower hazard for every 10-unit increase in global T scores (HR = 0.67; 95% CI 0.56–0.80). The study identified older HIV-infected individuals with NCI as a group needing special attention for the longevity of life. The study has considerable prognostic utility by not only predicting mortality hazard, but also future cognitive status.

We incorporated questions related to safety, effectiveness and other characteristics of systemic cancer treatment into a self-report questionnaire – the Therapy Preference Scale – that captures patients´ preferences. The authors asked 20 experts to assess content validity and an additional 20 experts, patients and community members to examine face validity and guide revisions. Key revisions included shortening the length, clarifying constructs and providing details to explain the context and trade-offs necessary to balance the risks and benefits of cancer treatment. The content validity index for the final questionnaire was 1.0, indicating that all questions were relevant. Reviewers expressed that the questionnaire would serve an important purpose. Experts, patients and community members guided revisions of the questionnaire and documented its value.

Purpose Prefabricated arrays with a limited number of electrodes offer an opportunity to hasten the diagnosis of seizures; however, their accuracy to detect seizures is unknown. We examined the utility of two limited-montage EEG setups for the detection of nonconvulsive seizures. Methods Thirty previously interpreted EEG segments with nonconvulsive seizures from 30 patients and 60 segments with background slowing or normal EEG from 60 patients were rendered in a bipolar "double banana" montage, a double distance "neonatal" montage, and a circumferential "hatband" montage. Experts reviewed 60 to 180 seconds long segments to determine whether seizures were present and if the EEG data provided were sufficient to make a decision on escalation of clinical care by ordering an additional EEG or prescribing anticonvulsants. The periodic patterns on the ictal-interictal continuum were specifically excluded for this analysis to keep the focus on definite electrographic seizures. Results The sensitivities for seizure of the neonatal and hatband montages were 0.96 and 0.84, respectively, when compared with full montage EEG, whereas the specificities were 0.94 and 0.98, respectively. Appropriate escalation of care was suggested for 96% and 92% of occurrences of seizure patterns in neonatal and hatband montages, respectively. When compared with clinical EEG, the sensitivities of the neonatal and hatband montages for seizure diagnosis were 0.85 and 0.69, respectively. Conclusions Nonconvulsive seizures were detected with high accuracy using the limited electrode array configuration in the neonatal and hatband montages. The sensitivity of the neonatal montage EEG in detecting seizures was superior to that of a hatband montage. These findings suggest that in some patients with nonconvulsive seizures, limited-montage EEG may allow to differentiate ictal and slow patterns.

Author(s): May, Pamela E; Heithoff, Abigail J; Wichman, Christopher S; Phatak, Vaishali S; Moore, David J; Heaton, Robert K; Fox, Howard S | Abstract: BackgroundSingle summary scores, such as the Global Deficit Score, are often used to classify overall performance on neuropsychological batteries. The factor structure of test scores that underlie Global Deficit Score in studies of people living with HIV (PLWH) was assessed to determine whether individual test scores loaded onto a unitary factor to summarize performance.SettingSecondary data analysis on baseline data of PLWH from National NeuroAIDS Tissue Consortium and CNS HIV Antiretroviral Therapy Effects Research (CHARTER) Study.MethodPrimary analyses included testing model structure and fit of neuropsychological test scores with confirmatory and exploratory factor analyses. Secondary analyses involved receiver operating characteristic curves, and associations with psychosocial and medical variables.ResultsParticipants with confounds were excluded, leading to 798 (National NeuroAIDS Tissue Consortium) and 1222 (CHARTER) cases. When confirmatory factor analysis models were structured to be consistent with theoretically-based cognitive domains, models did not fit adequately. Per exploratory factor analyses, tests assessing speeded information processing, working memory, and executive functions loaded onto a single factor and explained the most variance in both cohorts. This factor tended to be associated with age, estimated premorbid ability, and aspects of substance use history. Its relation to age, in context of demographically corrected neuropsychological scores, suggested accelerated aging.ConclusionResults indicate that individual neuropsychological tests did not load exactly onto expected domains, suggesting another framework for future analyses of cognitive domains. The possibility of a new index, and its use to assess cognitive impairment in PLWH, is suggested for further diagnostic and prognostic purposes.

Background and Objectives:Cardiac surgical interventions for children with trisomy 18 and trisomy 13 remain controversial, despite growing evidence that definitive cardiac repair prolongs survival. Understanding quality of life for survivors and their families therefore becomes crucial. Study objective was to generate a descriptive summary of parental perspectives on quality of life, family impact, functional status, and hopes for children with trisomy 18 and trisomy 13 who have undergone heart surgery.Methods:A concurrent mixed method approach utilising PedsQL™ 4.0 Generic Core Parent Report for Toddlers or the PedsQL™ Infant Scale, PedsQL™ 2.0 Family Impact Module, Functional Status Scale, quality of life visual analogue scale, and narrative responses for 10 children whose families travelled out of state to access cardiac surgery denied to them in their home state due to genetic diagnoses.Results:Parents rated their child’s quality of life as 80/100, and their own quality of life as 78/100 using validated scales. Functional status was rated 11 by parents and 11.6 by providers (correlation 0.89). On quality of life visual analogue scale, all parents rated their child’s quality of life as “high” with mean response 92.7/100. Parental hopes were informed by realistic perspective on prognosis while striving to ensure their children had access to reaching their full potential. Qualitative analysis revealed a profound sense of the child’s relationality and valued life meaning.Conclusion:Understanding parental motivations and perceptions on the child’s quality of life has potential to inform care teams in considering cardiac interventions for children with trisomy 18 and trisomy 13.

Background Aortic elasticity creates a cushion that protects the heart from pressure injury, and a recoil that helps perfuse the coronary arteries. TEVAR has become first-line therapy for many aortic pathologies including trauma, but stent-grafts stiffen the aorta and likely increase LV afterload. Objective Test the hypothesis that trauma TEVAR is associated with LV mass increase and adverse off-target aortic remodeling. Methods Computed Tomography Angiography (CTA) scans of 20 trauma TEVAR patients (17 M/3 F) at baseline [age 34.9 ± 18.5 (11.4-71.5) years] and 5.1 ± 3.1 (1.1-12.3) years after repair were used to measure changes in LV mass, LV mass index, and diameters and lengths of the ascending thoracic aorta (ATA). Measurements were compared with similarly-aged control patients without aortic repair (21 M/21 F) evaluated at similar follow-ups. Results LV mass and LV mass index of TEVAR patients increased from 138.5 ± 39.6 g and 72.35 ± 15.17 g/m to 173.5 ± 50.1 g and 85.48 ± 18.34 g/m at the rate of 10.03 ± 12.79 g/yr and 6.25 ± 10.28 g/m/yr, whereas in control patients LV characteristics did not change. ATA diameters of TEVAR patients increased at a rate of 0.60 ± 0.80 mm/yr, which was 2.4-fold faster than in controls. ATA length in both TEVAR and control patients increased at 0.58 mm/yr. Half of TEVAR patients had hypertension at follow-up compared to only 5% at baseline. Conclusions TEVAR is associated with LV mass increase, development of hypertension, and accelerated expansile remodeling of the ascending aorta. Although younger trauma patients may adapt to these effects, these changes may be even more important in older patients with other aortic pathologies and diminished baseline cardiac function.

School engagement protects against negative mental health outcomes; however, few studies examined the relationship between school engagement and attention-deficit hyperactivity disorder (ADHD) using an ecological framework. The aims were to examine: (1) whether school engagement has an independent protective association against the risk of ADHD in children, and (2) whether environmental factors have an association with ADHD either directly or indirectly via their association with school engagement. This cross-sectional study used data from the 2011–2012 National Survey of Children’s Health, which collected information about children’s mental health, family life, school, and community. The sample contained 65,680 children aged 6–17 years. Structural equation modeling was used to estimate the direct association of school engagement and ADHD and indirect associations of latent environmental variables (e.g., family socioeconomic status (SES), adverse childhood experiences (ACEs), environmental safety, and neighborhood amenities) and ADHD. School engagement had a direct and inverse relationship with ADHD (β = − 0.35, p

Background: Little is known about the composition, availability, integration, communication, perceived barriers, and work load of pediatric palliative care (PPC) providers serving children and adolescents with cancer. Objective: To summarize the structure and services of programs to better understand successes and gaps in implementing palliative care as a standard of care. Methods: Cross-sectional online survey about the palliative care domains determined by the Psychosocial Care of Children with Cancer and Their Families Workgroup. Subjects: A total of 142 surveys were completed with representation from 18 countries and 39 states. Results: Three-fourths of sites reported having a PPC program available for the pediatric cancer population at their center. Over one-fourth (28%) have been in existence less than five years. Fewer than half of sites (44%) offered 24/7 access to palliative care consultations. Neither hospital-based nor local community hospice services were available for pediatric patients at 24% of responding sites. A specific inpatient PPC unit was available at 8% of sites. Criteria for automatic palliative referrals (“trigger” diagnoses) were reported by 44% respondents. The presence of such “triggers” increased the likelihood of palliative principle introduction 3.41 times (p

Glaucoma represents a group of multifactorial diseases with a unifying pathology of progressive retinal ganglion cell (RGC) degeneration, causing irreversible vision loss. To test the hypothesis that RGCs are intrinsically vulnerable in glaucoma, we have developed an in vitro model using the SIX6 risk allele carrying glaucoma patient-specific induced pluripotent stem cells (iPSCs) for generating functional RGCs. Here, we demonstrate that the efficiency of RGC generation by SIX6 risk allele iPSCs is significantly lower than iPSCs-derived from healthy, age- and sex-matched controls. The decrease in the number of RGC generation is accompanied by repressed developmental expression of RGC regulatory genes. The SIX6 risk allele RGCs display short and simple neurites, reduced expression of guidance molecules, and immature electrophysiological signature. In addition, these cells have higher expression of glaucoma-associated genes, CDKN2A and CDKN2B, suggesting an early onset of the disease phenotype. Consistent with the developmental abnormalities, the SIX6 risk allele RGCs display global dysregulation of genes which map on developmentally relevant biological processes for RGC differentiation and signaling pathways such as mammalian target of rapamycin that integrate diverse functions for differentiation, metabolism, and survival. The results suggest that SIX6 influences different stages of RGC differentiation and their survival; therefore, alteration in SIX6 function due to the risk allele may lead to cellular and molecular abnormalities. These abnormalities, if carried into adulthood, may make RGCs vulnerable in glaucoma.

Background: Rural pediatricians and adult-trained hospice teams report feeling ill-prepared to care for children at end of life, resulting in geographies in which children are not able to access home-based services. Objectives: To develop a pediatric palliative care curriculum for inpatient nurses and adult-trained hospice teams caring for children in a rural region. Methods: Curriculum design and delivery was informed by local culture through an interdisciplinary, iterative development approach with confidence, intention, and support measured pre-, post-, and 4 months after delivery. A needs assessment was completed by pediatric nurses caring for children receiving palliative or end-of-life care to inform curricular content (phase 1). A curriculum was designed by an interdisciplinary pediatric palliative care team and piloted with nursing cohorts annually through educational conferences with monthly discussion series for 3 consecutive years (phase 2). Curricular content was then provided for 31 rural hospice team members (phase 3). Results: Self-reported confidence in caring for children increased by 1.1/10 points for adult-trained hospice team members. Mean score for intention to care for children increased by 5.2 points (sustained 5.1 points above baseline at 4 months). Perception of support in caring for children increased by 5 points (mean sustained 5.4 points above baseline at 4 months). Family needs, care goals, and symptom management were prioritized learning topics. Rural hospices previously unwilling to accept children enrolled pediatric patients in the 4 months following the conference. Conclusion: Grassroots curricular initiatives and ongoing educational mentorship can grow pediatric palliative and hospice services in rural regions.

Statement of problem To our knowledge, no data are available on the actual lighting that is used for visual shade matching in private dental offices. Purpose The purpose of this study was to determine the shade matching practices and interest in continuing education in dental practices and to determine the quantity and quality of the ambient lighting used during visual shade matching in a sample cohort of dentists in private practices. Material and methods Thirty-two private practices were enrolled, and each completed a 1-page survey on the clinic’s shade matching practices. A spectrophotometer was used to measure the ambient lighting in each practice, collecting data on color temperature (Kelvin), color rendering index (CRI), and light intensity (foot candles/fc). A 2-sided nonparametric sign test was used to compare the true median color temperature with the standard (5500°K). A 1-sided t test was used to compare the CRI with the standard (CRI >90) (α=.05 for all statistical analyses). Results All dental practitioners surveyed used mainly visual shade matching in their practices. Of those, 87.5% showed interest in attending continuing education on this topic, with 56.3% preferring a clinical demonstration course. The mean color temperature was 4152.9°K and was significantly different from the standard 5500°K ( P t test indicated that the mean CRI was less than 90 ( P =1). The 95% confidence interval for the intensity was 80.7 to 111.6 fc. Conclusions The ambient light in the majority of the 32 dental private practices measured was not ideal for visual shade matching.

Purpose This study investigates the clinical and cost effectiveness of switching from traditional vagus nerve stimulation (VNS) to responsive VNS (rVNS), which has an additional ictal tachycardia detection and stimulation (AutoStim) mode. Methods Retrospective chart review was used to collect data from patients with medically refractory epilepsy who underwent generator replacements. Patients with confounding factors such as medication changes were excluded. Vagus nerve stimulation parameters, seizure frequency, and healthcare costs were collected for the 1-year period following generator replacement with the rVNS device. Results Documented seizure frequency was available for twenty-five patients. After implant with rVNS, 28% of patients had an additional ≥ 50% seizure reduction. There was a significant decrease in the average monthly seizure count (p = 0.039). In patients who were not already free of disabling seizures (n = 17), 41.2% had ≥ 50% additional seizure reduction. There was no difference in healthcare costs during the 1-year follow-up after the rVNS implant compared with one year prior. Conclusions Ictal tachycardia detection and stimulation provided a significant clinical benefit in patients who were not free of disabling seizures with treatment from traditional VNS. There was no additional increase in healthcare costs during the first year after device replacement.

Background: Most rural adults do not meet current guidelines for physical activity (PA). A 12-week feasibility study tested the effectiveness of using the 5A’s model for PA counseling on rural adults’ PA behaviors. Methods: Inactive rural adults recruited from a primary care clinic were randomized to an intervention (n = 30) or control (n = 29) group. All subjects wore a Fitbit to track steps and active minutes. The intervention group completed action plans to improve self-regulatory PA strategies and received weekly motivational text messages to improve PA behaviors. Theory of planned behavior constructs and self-regulatory strategies of planning, goal setting, and tracking (steps and active minutes) were measured with both groups. The control group received the Fitbit only. Results: All individuals became more physically active; however, no significant differences between groups in active minutes or steps were found. All subjects, regardless of group, increased steps (P > .05). There were no statistically significant differences between groups on any of the theoretical variables. Conclusions: It is vitally important to continue to find ways to make PA a priority to improve the overall health and well-being of rural adults. Future research warrants adjusting the intervention dose and strategies to increase PA that can be maintained long term.

Human Papilloma Virus (HPV) is the most common sexually transmitted disease with over 14 million infections in 2008. Certain HPV types have been identified in up to 70% of cases of cervical and anal cancers. Despite being safe and effective, HPV vaccination rates remain low. Vaccination and demographic data was collected pre-and post-intervention. Among 13 thru 17-year-old cohort females were significantly more likely to be fully vaccinated. Assessment also found that patients insured by Medicaid were significantly more likely to be fully vaccinated than patients insured privately. Post-intervention vaccination rate is similar to baseline rates. There was non-significant improvement in HPV vaccination coverage after intervention. Male and privately insured patients of Creighton's Pediatric Clinic have lower HPV vaccination coverage than their counterparts. More direct efforts are needed in vaccination process and policy in the clinic to improve immunization against HPV among children and adolescents.

One goal of pediatric palliative care is to maintain quality of life for children and their families. Quality-of-life investigations may be enhanced by considering clinically important metrics in addition to statistical significance.The purpose of this study was to longitudinally evaluate the effect of time on quality of life and family impact for pediatric palliative care patients across all diagnoses and ages.This prospective quality-of-life study included administration of a 23-item PedsQL™ Measurement Model to evaluate for physical, emotional, social, and cognitive dimensions of the child's quality of life and a 36-item PedsQL Family Impact Module to assess for the familial impact at time of initial palliative care consultation, Month 6, and Month 12.All pediatric patients who received a palliative care consultation in our Midwestern free-standing children's hospital over a five-year period were included in the longitudinal study (n = 87).Repeated measures ANOVA was used to investigate how proxy-reported quality of life and family impact changed with time with attentiveness to also follow trends in minimal clinically important difference (MCID) metrics.The emotional domain showed a statistically significant positive trend over the first six months of palliative care involvement (p = 0.049), while the physical domain (p = 0.028) and daily activity (p = 0.039) showed a positive improvement for the full year. In using a standard of MCID, the physical, emotional, and cognitive domains improved in the quality-of-life scale and the communication, worry, and daily activity domains improved in the family impact scale over 12 months.In considering quality-of-life analyses for pediatric palliative care programmatic improvements, providers may consider analyzing not only for statistical significance in collective data sets but also for clinically important difference over time.

Background: The role of B-type natriuretic peptide (BNP) is less understood in the risk stratification of patients with an acute exacerbation of chronic obstructive pulmonary disease (AECOPD), especially in patients with normal left ventricular ejection fraction (LVEF). Methods: This retrospective study from 2008 to 2012 evaluated all adult patients with AECOPD having BNP levels and available echocardiographic data demonstrating LVEF ≥40%. The patients were divided into groups 1, 2, and 3 with BNP ≤ 100, 101 to 500, and ≥501 pg/mL, respectively. A subgroup analysis was performed for patients without renal dysfunction. Outcomes included need for and duration of noninvasive ventilation (NIV) and mechanical ventilation (MV), NIV failure, reintubation at 48 hours, intensive care unit (ICU) and total length of stay (LOS), and in-hospital mortality. Two-tailed P < .05 was considered statistically significant. Results: Of the total 1145 patients, 550 (48.0%) met our inclusion criteria (age 65.1 ± 12.2 years; 271 [49.3%] males). Groups 1, 2, and 3 had 214, 216, and 120 patients each, respectively, with higher comorbidities and worse biventricular function in higher categories. Higher BNP values were associated with higher MV use, NIV failure, MV duration, and ICU and total LOS. On multivariate analysis, BNP was an independent predictor of higher NIV and MV use, NIV failure, NIV and MV duration, and total LOS in groups 2 and 3 compared to group 1. B-type natriuretic peptide continued to demonstrate positive correlation with NIV and MV duration and ICU and total LOS independent of renal function in a subgroup analysis. Conclusion: Elevated admission BNP in patients with AECOPD and normal LVEF is associated with worse in-hospital outcomes and can be used to risk-stratify these patients.

The primary aim of this study was to determine the characteristics that current chairpersons in restorative dentistry, general dentistry, prosthodontics, and operative dentistry departments in U.S. dental schools feel are most relevant in contributing to their success. The secondary aim was to determine these individuals' rankings of the importance of a listed set of characteristics for them to be successful in their position. All 82 current chairs of the specified departments were invited to respond to an electronic survey. The survey first asked respondents to list the five most essential characteristics to serve as chair of a department and to rank those characteristics based on importance. Participants were next given a list of ten characteristics in the categories of management and leadership and, without being aware of the category of each individual item, asked to rank them in terms of importance for their success. A total of 39 chairpersons completed the survey (47.6% response rate; 83.3% male and 16.2% female). In section one, the respondents reported that leadership, vision, work ethic, integrity, communication, and organization were the most essential characteristics for their success. In section two, the respondents ranked the leadership characteristics as statistically more important than the management characteristics (p0.0001) for being successful in their positions.

We compared current Centers for Disease Control and Prevention surveillance criteria with the newer adult screening criteria (ASC) for identifying pediatric ventilator-associated pneumonia (VAP). Possible cases of VAP identified by ASC (n = 17) and cases of VAP identified by the older current surveillance criteria (n = 15) are comparable, but only 9 were identified by both. Positive end expiratory pressure was inferior to fraction of inspired oxygen in identifying ventilator-associated conditions by ASC.

This study evaluated learning outcomes and student perceptions of collaborative learning in an undergraduate nursing program. Participants in this 3-phase action research study included students enrolled in a traditional and an accelerated nursing program. The number of students who passed the unit examination was not significantly different between the 3 phases. Students had positive and negative perceptions about the use of collaborative learning.

The diagnostic value of tumor markers, carcinoembryonic antigen (CEA), cancer antigen (CA) 15-3, CA 19-9, CA 125, cytokeratin fragment (CYFRA), and neuron-specific enolase (NSE) in pleural fluid to differentiate between benign and malignant pleural effusion (MPE) has not yet been clearly established. A review of English language studies using human subjects was performed. Sensitivity and specificity values of the chosen tumor markers were pooled using a random effects model to generate hierarchical summary receiver operator curves to determine the diagnostic performance of each tumor marker. A total of 49 studies were included in the final analysis. Pooled sensitivity and specificity values for chosen tumor markers for diagnosing MPE are as follows: CEA, 0.549 and 0.962; CA 15-3, 0.507 and 0.983; CA 19-9, 0.376 and 0.980; CA 125, 0.575 and 0.928; CYFRA, 0.625 and 0.932; NSE, 0.613 and 0.884. The use of individual tumor markers in diagnosing MPE has many benefits (cost, invasiveness, and so forth). Although these tumor markers exhibit high specificity, the low sensitivity of each marker limits the diagnostic value. We conclude that tumor markers used individually are of insufficient diagnostic accuracy for clinical use. Tumor markers used in various combinations or from serum may have some potential worth further investigation.
