AbstractBackgroundSatisfaction is an important indicator of the quality of care during childbirth. Previous research found that a good environment at a health facility can increase the number of deliveries at that facility. In contrast, an unsatisfying childbirth experience could cause postpartum mental disorder. Therefore it is important to measure mothers’ satisfaction with their childbirth experiences. We tested whether the eight-item Client Satisfaction Questionnaire (CSQ-8) provided useful information about satisfaction with childbirth-related care. The government of the Philippines promotes childbirth at health facilities, so we tested the CSQ-8 in the Philippine cities of Ormoc and Palo.MethodsThis was a cross-sectional study. We targeted multigravid mothers whose last baby had been delivered at a hospital (without complications) and whose 2nd-to-last baby had been delivered at a hospital or at home (without complications). We developed versions of the CSQ-8 in Cebuano and Waray, which are two of the six major Filipino languages. Reliability tests and validation tests were done with data from 100 Cebuano-speaking mothers and 106 Waray-speaking mothers.ResultsBoth the Cebuano and Waray versions of the CSQ-8 had high coefficients of internal-consistency reliability (greater than 0.80). Both versions were also unidimensional, which is generally consistent with the English CSQ-8 in a mental-health setting. As hypothesized, the scores for data regarding the second-to-last delivery were higher for mothers who had both their second-to-last and their last delivery in a hospital, than for mothers who had their second-to-last delivery at home and their last delivery in a hospital (Cebuano: p < 0.001, rho = 0.51, Waray: p < 0.001, rho = 0.55).ConclusionsScores on the CSQ-8 can be used as indices of general satisfaction with childbirth-related services in clinical settings. This study also exemplifies a convenient method for developing versions of the CSQ-8 in more than one language. These versions of the CSQ-8 can now be used to assess mothers’ satisfaction, so that mothers’ opinions can be taken into account in efforts to improve childbirth-related services, which could increase the proportion of deliveries in medical facilities and thus reduce maternal mortality.
Adverse childhood experiences and the cardiovascular health of children: a cross-sectional study
Authors: Pretty Chelsea , O’Leary Deborah D , Cairney John , Wade Terrance J 
Published: December 2013

Abstract

Background
Adverse childhood experiences (ACEs), such as abuse, household dysfunction, and neglect, have been shown to increase adults’ risk of developing chronic conditions and risk factors for chronic conditions, including cardiovascular disease (CVD). Much less work has investigated the effect of ACEs on children’s physical health status that may lead to adult chronic health conditions. Therefore, the present study examined the relationship between ACEs and early childhood risk factors for adult cardiovascular disease.

Methods
1 234 grade six to eight students participated in school-based data collection, which included resting measures of blood pressure (BP), heart rate (HR), body mass index (BMI) and waist circumference (WC). Parents of these children completed an inventory of ACEs taken from the Childhood Trust Events Survey. Linear regression models were used to assess the relationship between experiencing more than 4 ACEs experienced, systolic BP, HR, BMI and WC. In additional analysis, ACEs were assessed ordinally in their relationship with systolic BP, HR, and BMI as well as clinical obesity and hypertension status.

Results
After adjustment for family education, income, age, sex, physical activity, and parental history of hypertension, and WC for HR models, four or more ACEs had a significant effect on HR (b = 1.8 bpm, 95% CI (0.1-3.6)) BMI (b =1.1 kg/m2, 95% CI (0.5-1.8)), and WC (b = 3.6 cm, 95% CI (1.8-5.3)). A dose–response relationship between ACE accumulation and both BMI and WC was also found to be significant. Furthermore, accumulation of 4 or more ACEs was significantly associated with clinical obesity (95th percentile), after controlling for the aforementioned covariates.

Conclusions
In a community sample of grade six to eight children, accumulation of 4 or more ACEs significantly increased BMI, WC and resting HR. Therefore, risk factors related to reported associations between ACEs and cardiovascular outcomes among adults are identifiable in childhood suggesting earlier interventions to reduce CVD risk are required.

Published: December 2013

Abstract

Background
Self-reported body weight is often used for calculation of Body Mass Index because it is easy to collect. Little is known about sources of error introduced by using bathroom scales to measure weight at home. The objective of this study was to evaluate the accuracy and consistency of digital versus dial-type bathroom scales commonly used for self-reported weight.

Methods
Participants brought functioning bathroom scales (n = 18 dial-type, n = 43 digital-type) to a central location. Trained researchers assessed accuracy and consistency using certified calibration weights at 10 kg, 25 kg, 50 kg, 75 kg, 100 kg, and 110 kg. Data also were collected on frequency of calibration, age and floor surface beneath the scale.

Results
All participants reported using their scale on hard surface flooring. Before calibration, all digital scales displayed 0, but dial scales displayed a mean absolute initial weight of 0.95 (1.9 SD) kg. Digital scales accurately weighed test loads whereas dial-type scale weights differed significantly (p < 0.05). Imprecision of dial scales was significantly greater than that of digital scales at all weights (p < 0.05). Accuracy and precision did not vary by scale age.

Conclusions
Digital home bathroom scales provide sufficiently accurate and consistent weights for public health research. Reminders to zero scales before each use may further improve accuracy of self-reported weight.
Hydrogen evolution reaction measurements of dealloyed porous NiCu
Authors: Koboski Kyla R , Nelsen Evan F , Hampton Jennifer R 
Published: December 2013

Abstract
Porous metals are of interest for their high surface area and potential for enhanced catalytic behavior. Electrodeposited NiCu thin films with a range of compositions were electrochemically dealloyed to selectively remove the Cu component. The film structure, composition, and reactivity of these samples were characterized both before and after the dealloying step using scanning electron microscopy, energy-dispersive spectroscopy, and electrochemical measurements. The catalytic behavior of the dealloyed porous Ni samples towards the hydrogen evolution reaction was measured and compared to that of the as-deposited samples. The dealloyed samples were generally more reactive than their as-deposited counterparts at low overpotentials, making the dealloying procedure a promising area of exploration for improved hydrogen evolution catalysts.
Performance evaluation of a MIMO channel model for simplified OTA test systems

Published: December 2013

Abstract
This paper shows performance evaluation results of the proposed multiple-input multiple-output (MIMO) channel model with simplified configuration for OTA measurement systems. The key feature of our proposal is the adoption of a simple antenna branch-controlled configuration for generating various Rayleigh fading environments composed of a number of multipath delayed waves. The scheme matches well with FPGA implementation with IF band signal processing. The channel model and its theoretical background, and the basic configuration of the measurement system are presented. From an eigenvalue analysis of the generated channel matrix, it is verified that an 8-probe antenna system can realize a very accurate multipath environment for the performance measurement of a 2 × 2 MIMO system, while a 12- or 16-probe antenna system can do the same for a 4 × 4 MIMO system.

Published: December 2013

Abstract

Background
Eosinophilic myocarditis is a rare and often under-diagnosed subtype of myocarditis with only around 30 cases published in the medical literature. In this article we present two patients with eosinophilic myocarditis with the aim to demonstrate the often elusive nature of the disease and present the current scientific literature on this topic.

Case presentation
A 76 years old Caucasian gentleman and a 36 years old Aboriginal gentleman both presenting with heart failure symptoms were eventually diagnosed with eosinophilic myocarditis after extensive evaluation. Their presentation, assessment, and medical management is explored in this article.

Conclusions
Eosinophilic myocarditis remains a rare and likely under-diagnosed subtype of myocarditis. The key features of this disease include myocardial injury in the setting of non-contributory coronary artery disease. Endomyocardial biopsy remains the definitive gold standard for diagnosis of noninfectious eosinophilic myocarditis. Non-invasive cardiac imaging in the setting of peripheral eosinophilia can be strongly suggestive of eosinophilic myocarditis with potential for earlier diagnosis. Failure to diagnose eosinophilic myocarditis and the delay of therapy may lead to irreversible myocardial injury. Therapies for this disease have yet to be validated in large prospective studies.

Abstract

Background
There is an overall paucity of data regarding the outcomes of patients with acetaminophen-associated toxic hepatitis in Taiwan. Therefore, the purpose of this study was to recruit a larger number of patients and to examine the clinical features, the degrees of toxic hepatitis, the physiological markers, and the clinical outcomes after intentional acetaminophen poisoning, and to determine what association, if any, might exist between these findings.

Methods
We examined the medical records of 187 patients with intentional acetaminophen poisoning who were examined at Chang Gung Memorial Hospital between 2000 and 2011. Patients were categorized into 2 groups according to hepatic complications, i.e. with (n = 15) or without (n = 172) toxic hepatitis. Demographic, clinical, and laboratory data were collected, and the mortality rate was analyzed.

Results
It was found that patients with toxic hepatitis had higher serum acetaminophen level (P = 0.007), but they also arrived to the hospital later (P < 0.001) than patients without toxic hepatitis. Furthermore, patients with toxic hepatitis showed higher incidences of acute respiratory failure (P = 0.012) than those shown by patients who did not have hepatitis. The laboratory examinations also revealed greater degrees of granulocytosis (P < 0.001) and poorer liver function tests (P < 0.001) in patients with hepatitis than in patients without hepatitis. Nevertheless, a univariate logistic regression model failed to identify any significant risk factors for toxic hepatitis complication after ingestion (P > 0.05). At the end of the analysis, 1 patient with toxic hepatitis died of liver failure. Finally, there was no significant difference in mortality between patients with and without hepatitis (P = 0.080).

Conclusion
The analytical data revealed that toxic hepatitis was not uncommon (15/187 or 8.0%) after acetaminophen overdose. Further studies are warranted.

PurposeTo examine the outcomes of patients with chemotherapy-sensitive mantle-cell lymphoma (MCL) following a first hematopoietic stem-cell transplantation (HCT), comparing outcomes with autologous (auto) versus reduced-intensity conditioning allogeneic (RIC allo) HCT and with transplantation applied at different times in the disease course.Patients and MethodsIn all, 519 patients who received transplantations between 1996 and 2007 and were reported to the Center for International Blood and Marrow Transplant Research were analyzed. The early transplantation cohort was defined as those patients in first partial or complete remission with no more than two lines of chemotherapy. The late transplantation cohort was defined as all the remaining patients.ResultsAuto-HCT and RIC allo-HCT resulted in similar overall survival from transplantation for both the early (at 5 years: 61% auto-HCT v 62% RIC allo-HCT; P = .951) and late cohorts (at 5 years: 44% auto-HCT v 31% RIC allo-HCT; P = .202). In both early and late transplantation cohorts, progression/relapse was lower and nonrelapse mortality was higher in the allo-HCT group. Overall survival and progression-free survival were highest in patients who underwent auto-HCT in first complete response. Multivariate analysis of survival from diagnosis identified a survival benefit favoring early HCT for both auto-HCT and RIC allo-HCT.ConclusionFor patients with chemotherapy-sensitive MCL, the optimal timing for HCT is early in the disease course. Outcomes are particularly favorable for patients undergoing auto-HCT in first complete remission. For those unable to achieve complete remission after two lines of chemotherapy or those with relapsed disease, either auto-HCT or RIC allo-HCT may be effective, although the chance for long-term remission and survival is lower.

Purpose High-dose interferon alfa-2b (HDI) has emerged as a potentially effective adjuvant therapy in patients with resected melanoma at high risk of recurrence. Evidence suggests it may be the early, very-high-dose part of the regimen that is critical. This pilot study sought to provide an early indication of whether the same effects can be achieved with the intravenous component of HDI alone and inform the feasibility and design of a phase III trial. Patients and Methods Patients with stage 2B, 2C, 3B, and 3C melanoma were randomly assigned to receive interferon alfa-2b (IFN-α-2b) 20 MIU/m2 intravenously (IV) daily 5 days per week for 4 weeks (arm A) versus the same regimen followed by IFN-α-2b 10 MIU/m2 administered subcutaneously three times per week for 48 weeks (arm B) and observed for relapse-free survival (RFS) and overall survival. Results Between 2003 and 2009, 194 patients were enrolled (arm A, 96; arm B, 98). After median follow-up of 39.5 months, RFS was 22.7 months (95% CI, 14.1 to 38.1 months) in arm A versus 33.3 months (95% CI, 18.2 to not reached) in arm B (P = .28). The proportions of patients free of relapse at 2 years were 50% and 54.1% (P = .569; hazard ratio, 0.89), respectively. Overall survival favored arm B (median, 41.5 months v not reached; P = .05). Conclusion Clinical outcomes were better in patients who had the longer regimen. Our results do not support either the use of a month of IV HDI alone in place of the year-long regimen or the initiation of a larger trial on this question.

Background It is a challenge for oncologists to distinguish patients with breast cancer who can forego adjuvant systemic treatment without negatively affecting survival from those who cannot. Risk prediction models (RPMs) have been developed for this purpose. Oncologists seem to have embraced RPMs (particularly Adjuvant!) in clinical practice and often use them to communicate prognosis to patients. We performed a systematic review of published RPMs and provide an overview of the prognosticators incorporated and reported clinical validity. Subsequently, we selected the RPMs that are currently used in the clinic for a more in-depth assessment of clinical validity. Finally, we assessed lay comprehensibility of the reports generated by RPMs. Methods Pubmed, EMBASE, and Web of Science were searched. Two reviewers independently selected relevant articles and extracted data. Agreement on article selection and data extraction was achieved in consensus meetings. Results We identified RPMs based on clinical prognosticators (N = 6) and biomolecular features (N = 14). Generally predictions from RPMs seem to be accurate, except for patients ≤ 50 years or ≥ 75 years at diagnosis, in addition to Asian populations. RPM reports contain much medical jargon or technical details, which are seldom explained in lay terms. Conclusion The accuracy of RPMs' prognostic estimates is suboptimal in some patient subgroups. This urgently needs to be addressed. In their current format, RPM reports are not conducive to patient comprehension. Communicating survival probabilities using RPM might seem straightforward, but it is fraught with difficulties. If not done properly, it can backfire and confuse patients. Evidence to guide best communication practice is needed.
Origins of Karenia brevis harmful algal blooms along the Texas coast

Published: December 2013

Lay AbstractHarmful algal blooms (HABs) in the Gulf of Mexico are primarily caused by the dinoflagellate species Karenia brevis. During blooms, toxins produced by K. brevis are concentrated by suspension‐feeding shellfish, which, if consumed by humans, can cause neurotoxic shellfish poisoning, and can lead to fish kills. A complication in understanding the underlying cause of the blooms is that the observed rate of growth of the bloom is too high to be explained by algal growth alone. Additionally, blooms occur sporadically in Texas waters, compared with more predictable blooms on the western Florida continental shelf. This study proposes a series of physical mechanisms to explain the interannual variability of bloom occurrences. Wind data along the coast are weaker on average in years in which HAB events occur. We propose that typical northward summer winds bring higher concentrations of cells from the southern Gulf of Mexico and then these cells are transported toward the Texas coastline by the southwestward fall winds. Strong winds wash out the accumulating cells, whereas weaker winds allow algal cells to aggregate.
Creating Minimum Harm Practice (MiHaP): a concept for continuous improvement
Authors: Singh Ranjit 
Published: December 2013

The author asks for the attention of leaders and all other stakeholders to calls of the World Health Organization (WHO), the Institute of Medicine (IOM), and the UK National Health Service (NHS) to promote continuous learning to reduce harm to patients. This paper presents a concept for structured bottom-up methodology that enables and empowers all stakeholders to identify, prioritize, and address safety challenges. This methodology takes advantage of the memory of the experiences of all persons involved in providing care. It respects and responds to the uniqueness of each setting by empowering and motivating all team members to commit to harm reduction. It is based on previously published work on “Best Practices Research (BPR)” and on “Systematic Appraisal of Risk and Its Management for Error Reduction (SARAIMER)”. The latter approach, has been shown by the author (with Agency for Healthcare Research and Quality (AHRQ) support), to reduce adverse events and their severity through empowerment, ownership and work satisfaction. The author puts forward a strategy for leaders to implement, in response to national and international calls for Better health, Better care, and Better value (the 3B’s of healthcare) in the US Patient Protection and Affordable Care Act. This is designed to enable and implement “A promise to learn- a commitment to act”. AHRQ has recently published “A Toolkit for Rapid-Cycle Patient Safety and Quality Improvement” that includes an adapted version of SARAIMER.

The Pervasive Media Cookbook: Cooking up – communicating Pervasive Media
Authors: Dovey Jon , Fleuriot Constance 
Published: December 2013

Abstract
This work emerges from an ongoing knowledge exchange partnership between the Pervasive Media Studio Bristol, UK, and the University of the West of England’s Digital Cultures Research Centre (DCRC). The development of a shared vocabulary for ‘Pervasive Media’ formed a central question in an AHRC funded Knowledge Transfer Fellowship (KTF) undertaken by the DCRC in the Pervasive Media Studio 2010–2012. Using a collaborative process with Pervasive Media producers we addressed the question of a general language for Pervasive Media, and how we together begin to define this emergent field. A common set of terms and definitions is an important precursor for the development of this field of innovation in which multi-disciplinary teams and general publics are having to come to terms with these new forms of media experience. Project outputs have been published online in the form of the Pervasive Media Cookbook (2012). The cookbook documents a variety of case studies of Pervasive Media experiences, as well as including essays and thought pieces on relevant themes that have emerged over the course of the project. Dissemination in a form that is easily accessible to our creative industries participants is an essential element of our research process.
