Authors: Tolvanen J. , Hannu J. , Palosaari J. , Nelo M. , Jantunen H. 
Published: June 2016

A screen‐printed mechanical switch based on an electrode structure on stretchable polyurethane (PU)‐foam film, Platilon U 4021, combined with a piezoelectric actuator, Smart Material MFC M‐4010‐P1, is proposed. The minimum actuation voltage of the prepared component is 300 V. The measured resistance was 2 Ω while closed and >0.5 TΩ when open. The electrode structure endured on average of up to 15.5 M cycles with movement ≥100 times greater than the ≤1 µm required for actuation. The results suggest that the switch could be advantageous for various e‐textile applications.

Published: June 2016

Issue addressedRates of sexually transmissible infections among young people are high, and there is a need for innovative, youth‐focused sexual health promotion programs. This study evaluated the effectiveness of the Sharing Stories youth theatre program, which uses interactive theatre and drama‐based strategies to engage and educate multicultural youth on sexual health issues. The effectiveness of using drama‐based evaluation methods is also discussed.MethodsThe youth theatre program participants were 18 multicultural youth from South East Asian, African and Middle Eastern backgrounds aged between 14 and 21 years. Four sexual health drama scenarios and a sexual health questionnaire were used to measure changes in knowledge and attitudes.ResultsParticipants reported being confident talking to and supporting their friends with regards to safe sex messages, improved their sexual health knowledge and demonstrated a positive shift in their attitudes towards sexual health. Drama‐based evaluation methods were effective in engaging multicultural youth and worked well across the cultures and age groups.ConclusionsTheatre and drama‐based sexual health promotion strategies are an effective method for up‐skilling young people from multicultural backgrounds to be peer educators and good communicators of sexual health information. Dramabased evaluation methods are engaging for young people and an effective way of collecting data from culturally diverse youth.So what?This study recommends incorporating interactive and arts‐based strategies into sexual health promotion programs for multicultural youth. It also provides guidance for health promotion practitioners evaluating an arts‐based health promotion program using arts‐based data collection methods.

Published: June 2016

S700 is a high-strength steel recently developed by Tata Steel. This paper describes the residual stress distributions in a multi-pass gas-metal-arc weld (GMAW), a single pass autogenous laser weld (ALW) and a multi-pass ultra-narrow gap laser weld (NGLW) in 13 mm thick high-strength (S700) steel plates, as measured by X-ray diffraction and the contour method. The relationships between microstructural variation and residual stress distributions were investigated. It was found that solid-sate phase transformations from austenite to ferrite, bainite and martensite changed both the magnitude and distribution of residual stresses in the three different welded specimens. The width of the regions sustaining tensile stress in each specimen decreased in the following order: GMAW > ALW > ultra-NGLW. This paper is part of a Themed Issue on Measurement, modelling and mitigation of residual stress.
Determination of residual stress within complex-shaped coarse-grained cobalt–chromium biomedical castings
Authors: Conroy B. P. , Tanner D. A. 
Published: June 2016

Cast ASTM F75 femoral knee implant components distort during manufacture due to residual stress re-distribution or inducement. These castings pose a number of challenges for residual stress determination methods; they have a complex geometry, their microstructure is inhomogeneous, they work-harden rapidly and they have a coarse, elastically anisotropic grain structure. The contour method is anticipated to be the most promising residual stress determination technique. X-ray diffraction is feasible for components which have experienced plastic deformation on their surface which results in refined diffracting domains. Centre-hole drilling is feasible, but the influence of stress induced from drilling and the effect of coarse grain structure is unknown. Neutron diffraction is challenging also due to a coarse grain structure and difficult nuclear material properties. This paper is part of a Themed Issue on Measurement, modelling and mitigation of residual stress.
Measuring the Relationship between Sportfishing Trip Expenditures and Anglers’ Species Preferences
Authors: Long James M. , Melstrom Richard T. 
Published: June 2016

Abstract
We examined the relationship between fishing trip expenditures and anglers’ species preferences from a survey of Oklahoma resident anglers conducted in 2014. Understanding patterns in fishing trip expenditures is important because a significant share of state wildlife agency revenue comes from taxes on purchases of fishing equipment. Presently, there is little research that addresses the question of how spending levels vary within groups of sportspersons, including anglers. We used regression analysis to identify a relationship between trip spending and several preference variables, and included controls for other characteristics of fishing trips, such as location, party size, and duration. We received 780 surveys for a response rate of 26%, but only 506 were useable due to missing data or nonfishing responses. Average trip expenditures were approximately US$140, regardless of species preferences, but anglers who preferred to fish for trout and black bass tended to spend more than those who preferred to fish for catfish and panfish. These results were even more pronounced when location was considered, those who last fished at lakes spending more than those who fished at rivers or ponds. The results underscore the differences in spending among anglers with different preferred species and fishing locations.

Hemiepiphysiodesis for Idiopathic Genu Valgum: Percutaneous Transphyseal Screw Versus Tension-band Plate
Authors: Park Hoon , Park Minjung , Kim Sung Min , Kim Hyun Woo , Lee Dong Hoon 
Published: June 2016

Background:
The aim of this study was to compare the outcomes of angular deformity correction by percutaneous hemiepiphysiodesis using transphyseal screw (PETS) or tension-band plating (TBP) in growing children with idiopathic genu valgum with emphasis on the rate of deformity correction.

Methods:
We retrospectively reviewed cases of hemiepiphysiodesis for angular deformity in lower extremities between 2009 and 2014. A total of 90 limbs in 33 patients received PETS and 60 limbs in 24 patients received TBP. Angular measurements were compared preoperatively and at the time of hardware removal. The amount and rate of angular deformity correction were compared between the 2 groups. Potential factors affecting correction velocity were investigated using multivariate analysis.

Results:
Angular correction was achieved in all patients. The mean rate of correction was more rapid with PETS than with TBP at both the distal femur (0.92 vs. 0.64 deg./mo, respectively; P<0.001) and proximal tibia (0.72 vs. 0.55 deg./mo, respectively; P=0.019). Multivariate analysis showed that the used implant significantly affected the rate of correction: PETS demonstrated faster correction velocity than TBP (−0.26, 95% confidence interval, −0.35 to −0.17, P<0.001).

Conclusions:
Both PETS and TBP techniques result in satisfactory correction of coronal angular deformity in patients with idiopathic genu valgum. However, the observed rate of correction was faster with PETS than TBP. Correction with PETS, rather than TBP, may better serve patients near skeletal maturity.

Level of Evidence:

Abstract

Objective:
The aim of the study was to evaluate the effectiveness of aerobic physical activity in reducing the frequency of hepatic steatosis and metabolic and cardiovascular risk in postmenopausal women with nonalcoholic fatty liver disease (NAFLD).

Methods:
Forty sedentary postmenopausal women (mean age 55.3 ± 8.0 y) with biopsy-proven NAFLD were randomly divided into two groups: an exercising group (19 participants) and a control group (nonexercising, 21 participants). The exercise group underwent a supervised aerobic physical activity program of 120 min/wk for 24 weeks. The anthropometric parameters; body composition; hepatic, lipid, and glycemic profiles; homeostasis model assessment of insulin resistance index; cytokines; transient elastography (FibroScan; liver stiffness/controlled attenuation parameter); and cardiopulmonary exercise test were evaluated at baseline and after 24 weeks of protocol.

Results:
At baseline there were no significant differences in anthropometric, metabolic, and inflammatory parameters—stiffness and liver fat content by FibroScan between the groups. After 24 weeks, we observed a decrease of waist circumference, an increase of high-density lipoprotein cholesterol levels (P < 0.05), and improved cardiopulmonary functional capacity in the exercise group. In addition, the controlled attenuation parameter analysis showed no significant decrease of hepatic steatosis in the exercise group. With regard to the systemic inflammation, there were, however, no significant differences in the cytokines between the groups.

Conclusions:
An aerobic physical activity program of 24 weeks in NAFLD postmenopausal women showed improvement in some variables such as waist circumference, high-density lipoprotein cholesterol, and cardiopulmonary performance that may be beneficial in improving cardiovascular risk factors in this population.

Abstract

Objective:
To determine if the miR-449b polymorphism, rs10061133 A>G, is associated with premature ovarian insufficiency (POI) pathogenesis.

Methods:
From January 2011 to December 2014, a total of 148 individuals with POI and 225 age-matched controls were collected from the Center for Reproductive Medicine, 1st Affiliated Hospital of Anhui Medical University (Hefei, China). Genotyping of miR-449b rs1006113 was performed using matrix-assisted laser desorption ionization time-of-flight-based mass spectrometry.

Results:
Rs10061133 A>G is a highly conserved SNP locus in the mature area of miR-449b. Association analysis shows that the rs10061133 AA genotype is a risk factor for POI.

Conclusions:
Our study provides the first evidence that the miR-449b rs10061133 AA genotype is associated with POI risk.

Published: June 2016

Abstract

Objective:
The aim of the study was to compare the natural menopause ages of healthy women with those of women with methotrexate (MTX)-treated rheumatoid arthritis (RA), and to specifically assess the effect of disease onset and activity and the use of MTX on the age of the last menstruation.

Methods:
We performed a retrospective review of medical records to identify the ages at which menopause occurred in women with premenopausal RA treated with MTX and in women with postmenopausal onset, irrespective of therapy. Natural menopause ages were also compared between participants with and without RA.

Results:
Women with premenopausal onset of RA underwent menopause at a significantly younger age than did healthy women (P < 0.001) or those with postmenopausal disease onset (P = 0.001). Menopause also occurred at younger ages in participants with postmenopausal disease onset than in healthy controls (P = 0.012). The study suggested that menopause age was positively correlated with the age at which RA was diagnosed (R = 0.51; P < 0.001) in women with premenopausal RA onset, but was independent of the participant's age at menarche, number of pregnancies, or MTX therapy. Participants with RA onset at ≤ 35 years of age had a ninefold higher risk of premature menopause (P = 0.008).

Conclusions:
The age at which menopause occurs in a patient with RA depends on the patient's age at the time of disease onset and its duration, but is not influenced by MTX treatment.
Development of Feeding Cues During Infancy and Toddlerhood

Published: June 2016

Abstract

Purpose:
To enhance responsive feeding, this study aimed to characterize the development of feeding cues during infancy and toddlerhood.

Study Design and Methods:
A secondary analysis was performed on a dataset of first-time, low-income African American mother–infant pairs assessed at infant age 3, 6, 9, 12, and 18 months. A subsample with the 15 highest, middle, and lowest infant body mass index (BMI) Z-scores at 18 months was selected (n = 45). Using video-recorded home feedings, early, active, and late receptiveness and fullness cues were assessed using the Responsiveness to Child Feeding Cues Scale at each time point. Descriptive statistics were used to characterize development.

Results:
Early receptiveness cues were relatively rare over time, whereas active receptiveness cues were much more common. However, there were changes over time. For example, settling into the feeding decreased from ~50% at 3 and 6 months to 4.8% by 18 months, whereas postural attention and reaching for food increased after 6 months. In the first 6 months, falling asleep and decreasing muscle tone and activity level were the most common early fullness cues. Thereafter, taking interest in surroundings was most prevalent. Active fullness cues became increasingly diverse after 6 months, led by more assertive cues such as pushing or pulling away and communicating “no” verbally or nonverbally.

Clinical Implications:
These findings provide an empirical description of waxing and waning in feeding cues and indicate increasing intentionality of cues over the first 18 months of life. Knowing common cues across development may aid clinicians in enhancing parental feeding responsiveness, avoiding overfeeding, thereby decreasing risk of early childhood obesity.
Interdisciplinary Feeding Team

Published: June 2016

Abstract
Pediatric feeding difficulties are complex and multifactorial in nature. Children who need assessment and individualized treatment for complex feeding problems are best served by an interdisciplinary treatment team. The medical, motor, and behavioral approach to treating pediatric feeding problems is presented as an avenue to treatment. By necessity, this approach requires a well-functioning interdisciplinary team, including nurses, physicians, registered dietitians, and feeding therapists (speech-language pathologists, occupational and physical therapists). We describe a robust interdisciplinary feeding team that applies a medical, motor, and behavioral approach to treating pediatric feeding problems. Within this team, pediatric gastroenterology nurse practitioners, dietitians, and speech pathologists function as integral members of the team. Description of each team member's expertise is provided and how they operate to support children with feeding problems and their families.
Physical Basis of Large Microtubule Aster Growth
Authors: Ishihara Keisuke , Korolev Kirill S. , Mitchison Timothy J. 
Published: June 2016

AbstractMicrotubule asters - radial arrays of microtubules organized by centrosomes - play a fundamental role in the spatial coordination of animal cells. The standard model of aster growth assumes a fixed number of microtubules originating from the centrosomes. However, aster morphology in this model does not scale with cell size, and we recently found evidence for non-centrosomal microtubule nucleation. Here, we combine autocatalytic nucleation and polymerization dynamics to develop a biophysical model of aster growth. Our model predicts that asters expand as traveling waves and recapitulates all major aspects of aster growth. As the nucleation rate increases, the model predicts an explosive transition from stationary to growing asters with a discontinuous jump of the growth velocity to a nonzero value. Experiments in frog egg extract confirm the main theoretical predictions. Our results suggest that asters observed in large frog and amphibian eggs are a meshwork of short, unstable microtubules maintained by autocatalytic nucleation and provide a paradigm for the assembly of robust and evolvable polymer networks.
Williams Syndrome-Specific Neuroarchitectural Profile and Its Associations with Cognitive Features

Published: June 2016

AbstractWilliams Syndrome (WS), a rare genetic disorders caused by hemizyous deletion of ~26 genes on the chromosome 7, has unique cognitive features and neuroanatomic abnormalities. Limited in statistical power due to its rareness had led to inconsistent in many direct comparisons using structural magnetic resonance imaging (MRI), and their associations with cognitive features of WS are not clear. Here, we used a novel approach to derive a WS specific neuroarchitectural profile and tested its association with cognitive features of WS. Using a WS adult cohort (n = 43), we trained a logistic elastic-net model to extract a sparse representation of WS specific neuroarchitectural profile. The predictive performances are robust within the training cohort (leave one out cross-validation AUC = 1.0) and generalized well in an independent teenager WS cohort (n = 60, AUC = 1.0). The WS specific neuroarchitectural profile includes multiple MRI measurements in the orbitofrontal cortex, superior parietal cortex, Sylvian fissures, and basal ganglia, whereas its variations reflect the underlying size of hemizygous deletion, and mediated the disease impact on the cognitive features of WS. In this study, we demonstrate the robustness of the derived WS specific neuroarchitectural profile, suggesting the joint developmental abnormalities in the cortical-subcortical circuitry cause the unique features of WS cognition.
Impact of indoor facilities management on the quality of life of the elderly in public housing
Authors: Leung Mei-yung , Yu Jingyu , Chow Hoyan 
Published: June 2016

Purpose
The aging population is growing rapidly, causing significant increases in the demand for public housing. Normally, the elderly rely heavily on the facilities available in their living environment to maintain their quality of life (QoL). However, most public housing is not purposely designed for the elderly, and, thus, has inappropriate facilities, which often have a negative impact upon the physical and psychological health of residents. This paper aims to investigate the relationships between the indoor facilities management (FM) of public housing and the QoL of elderly persons.

Design/methodology/approach
Based on an extensive literature review, a questionnaire has been designed and distributed among elderly residents of different public housing buildings. To investigate the impact of indoor FM on the QoL of the senior residents in public housing, statistical analysis methods including reliability analysis and multiple regression modeling were adopted.

Findings
The study identified 12 indoor FM factors and six QoL domains (i.e. overall QoL, physical and psychological health, independence, social relationship and living environment). The results also reveal that space planning and bathroom influence most QoL domains, including overall QoL, physical/psychological health, independence and living environment of the elderly; electricity and noise mainly affect physical health and independence, while noise is negatively related to elderly QoL; and supporting facilities (including windows and doors, indoor decoration, non-slip floors and accessibility) have a positive impact on psychological health and social relationships.

Practical implications
Based on the current findings, several practical recommendations are made for the designers and facilities managers, including wide corridors for individuals with wheelchairs, the installation of single-lever-type mixers to provide a stable hot water supply and a window designed to get as much natural light as possible.

Originality/value
This paper provides a clear picture about elderly special requirements on indoor FM and their QoL. It can assist architects, engineers and facilities managers in public housing to understand elderly needs and improve FM during design and operation stages for enhancing QoL of elderly residents in public housing buildings.
Establishing a radon management program for public university facilities
Authors: Webber William Brent , Fotopulos Chris Peter 
Published: June 2016

Purpose
The purpose of this paper is to elucidate best approaches for facility radon management in a resource-limited environment such as a public university. Radon exposures are believed to be a risk factor for lung cancer. However, the degree to which typical indoor radon levels within settings such as the university campus contribute to lung cancer risk is controversial. The authors sought to develop a risk-balancing approach to safe and cost-efficient facility radon management.

Design/methodology/approach
The authors collected pilot monitoring data to determine radon activity levels at a large public university within a projected high-radon region of the southeastern USA, then reviewed scientific literature, trade literature and regulatory guidance to determine radon risk knowledge and best practices for mitigation. From this body of data and information, the authors determined the safest and most resource-effective means for campus radon management.

Findings
The developed program for comprehensive radon management included guidance on building selection for most effective use of monitoring, tiered response and mitigation strategies based on radon activity levels and faculty, staff and student education.

Research Limitations/implications
The radon management strategies might not be generalizable to facilities with usage patterns that differ from a public university, and should be extrapolated with caution.

Practical Implications
This paper shows how building managers can address indoor radon in a manner that maximizes both safety and cost-efficiency.

Originality/value
This paper fulfills a need for evidence-based and prudent approaches to radon management for campuses with mixed residential, educational and occupational contexts and limited resources.
