Management factors affecting the use of pasture by table chickens in extensive production systems

Whether chickens will make proper use of pasture is a problem experienced by producers of free-range and organic chickens. The aims of this project are to identify husbandry techniques and aspects of system design that encourage good pasture use. Two studies have been conducted comprising a winter and a summer flock. The aim of the winter flock was to examine the effect of outdoor artificial shelter on pasture usage. This was done for female Ross 308 birds grown to day 56, and ISA 657 birds grown to day 81. In summer, ISA 657 birds were grown to day 81. Treatments were either standard or enriched brooding, with pasture only or enriched pasture. Standard brooding was in a controlled environment house until day 42. Enriched brooding was in naturally ventilated houses in which birds had sight of pasture from an early age and access from day 21. Enriched pasture included artificial shelter, with straw bales and a conifer “wigwam” used to provide natural shelter. Chickens may be encouraged to go outdoors by brooding in a less “controlled” environment than that used for intensive broilers, and by allowing access to pasture when young. However, mortality was higher. Conifer wigwams may offer a means for more even use of pasture and better distribution of droppings

Conservative management of lymphoedema in children: A systematic review

This article is published online with Open Access and distributed under the terms of the Creative Commons Attribution Non-Commercial License.PURPOSE: A systematic literature review was conducted to determine best practice conservative management of pediatric lymphoedema. METHOD: The PRISMA protocol was followed; a search of Ovid Medline, Cinahl and Scopus was conducted using the search terms children OR pediatric OR adolescent AND lymphoedema OR lymphedema. Studies about management or treatment of lymphoedema in children were included while studies about filariasis, imaging, pathology, secondary lymphoedema, surgical techniques, central lymphoedema and those with participants with a median age greater than 18 years were excluded. RESULTS: Of 738 possible studies identified, eight studies were eligible for inclusion in the review: four case reports, two retrospective service reviews and two prospective studies investigating different interventions. All studies were rated using the NHMRC hierarchy of evidence and appraised by both authors using the McMaster University Critical Review Form. Studies were of low quality with poor descriptions of management, small sample size, unclear and inconsistent methodology and irreproducible outcome measures. CONCLUSION: This review identified low level evidence to support the use of pneumatic compression in the management of pediatric lymphoedema. Further research is required to identify optimal parameters for application of pneumatic compression and to investigate the use of other interventions for conservative management of pediatric lymphoedema

Copyright © 2016. This manuscript version is made available under the CC-BY-NC-ND 4.0 license http://creativecommons.org/licenses/by-nc-nd/4.0/ This author manuscript is made available following 12 month embargo from date of publication (19 Dec 2016) in accordance with publisher’s copyright policyBackground To date, the significance of factors purported to be associated with subacromial shoulder impingement (SSI) and what differences, if any, are present in those with SSI compared to a matched asymptomatic population has not been identified. Gaining information about differences between people with SSI and asymptomatic people may direct clinicians towards treatments that impact upon these differences. Objective Compare the assessment findings of factors suggested to be associated with SSI; passive posterior shoulder range, passive internal rotation range, resting cervical and thoracic postures, active thoracic range in standing and scapula positioning between cases experiencing SSI and a matched asymptomatic group (controls). Method Fifty one SSI cases and 51 asymptomatic controls were matched for age, gender, hand dominance and physical activity level. The suggested associated factors were measured bilaterally. Independent t-tests were used to compare each of these measurements between the groups. Any variables for which a significant difference was identified, were then included in a conditional logistic regression analysis to identify independent predictors of SSI. Results The SSI group had significantly increased resting thoracic flexion and forward head posture, as well as significantly reduced upper thoracic active motion, passive internal rotation range and posterior shoulder range than the matched asymptomatic group. No independent predictors of SSI were identified in conditional logistic regression analysis. Conclusion Thoracic posture, passive internal rotation range and posterior shoulder range were significantly different between cases experiencing SSI and a matched asymptomatic group

Measurement of Lumbar Multifidus Asymmetry in Amateur Cricket Pace Bowlers using Real-Time Ultrasound

International Journal of Exercise Science 11(3): 875-885, 2018. Objectives: To determine if lumbar multifidus asymmetry existed between the fifth lumbar (L5) and 1stsacral (S1) spinal level in a group of amateur cricket pace bowlers and a healthy non-cricketing group of males, and to determine if there were significant differences between groups in lumbar multifidus asymmetry at rest, on contraction, or during activation. Design: A prospective single blinded cross-sectional study. Methods: Forty healthy participants were recruited to two groups: an amateur cricket pace bowling group (n=20) and a non-cricketing group (n=20). Bilateral real-time ultrasound imaging of lumbar multifidus was conducted at the L5/S1 level in a resting and contracted state. Muscle thickness was measured and percentage activation was calculated. A force probe device was used to standardise force, inclination and roll of the ultrasound probe during real-time ultrasound imaging. Results: There was evidence of asymmetry in both groups, but differences between dominant and non-dominant sided lumbar multifidus thickness were non-significant. Between group comparisons of lumbar multifidus asymmetry indicated no significant difference for rest or activation. However, the cricket group had a significantly greater asymmetry of lumbar multifidus when contracted compared to controls (p=0.04). Conclusions: The results indicate that amateur cricket pace bowlers had significantly greater contracted lumbar multifidus asymmetry than non-cricketers. The resting lumbar multifidus asymmetries demonstrated previously in elite pace bowlers were not found in this population. Future research should investigate lumbar multifidus asymmetry in amateur pace bowlers in relation to lower back injury, and make comparisons between amateur and elite cricket pace bowlers

A randomized, comparative trial: does pillow type alter cervico-thoracic spinal posture when side lying?

This is an Open Access article which permits unrestricted noncommercial use, provided the original work is properly cited.Background: Many patients ask for advice about choosing a pillow. This research was undertaken to determine if pillow type alters cervico-thoracic spine position when resting in the side-lying position. Aim: To investigate the effect of different pillow shape and content on the slope of cervico-thoracic spine segments when side lying. Materials and methods: The study was a randomized blinded comparative trial set in a laboratory that replicated a bedroom. The subjects were side sleepers aged over 18 years. Exclusion criteria were history of surgery to the cervico-thoracic spine, an injury or accident to the cervico-thoracic spine in the preceding year, or currently receiving treatment for neck symptoms. Each participant rested in a standardized side-lying position for 10 minutes on each of the trial pillows: regular shaped polyester, foam, feather, and latex pillows, and a contour shaped foam pillow. Reflective markers were placed on external occipital protuberance (EOP), C2, C4, C7, and T3, and digital images were recorded of subjects at 0 and 10 minutes on each pillow. Images were digitized using each reflective marker and the slope of each spinal segment calculated. Univariate analysis of variance models were used to investigate slope differences between pillows at 0 and 10 minutes. Significance was established at P < 0.01 to take account of chance effects from repeated measures and multiple comparisons. Results: At 0 and 10 minutes, the EOP-C2, C2-C4, and C4-C7 segmental slopes were significantly different across all pillows. Significant differences were identified when comparing the feather pillow with the latex, regular and contour foam pillows, and when comparing the polyester and foam contour pillows. The regular and contour foam pillows produced similar slopes at all spinal segments. Conclusion: Cervico-thoracic spinal segment slope alters significantly when people change from a foam, latex, or polyester pillow to a feather pillow and vice versa. The shape of a foam pillow (contour versus regular shape) does not significantly alter cervico-thoracic spinal segment slope

Dual Benefits of a Student-Assisted Interprofessional Men’s Healthy Lifestyle Pilot Program

Reprinted by permission of SAGE PublicationsMen are less willing to seek health professional advice than women and die more often than women from preventable causes. Therefore, it is important to increase male engagement with health initiatives. This study reports the outcomes of a student-assisted, interprofessional, 12-week health program for overweight adult males. The program included weekly health education and structured, supervised group exercise sessions. Thirteen males (participants) and 18 university students (session facilitators) completed the program. Participants were assessed for a range of health and physical activity measures and health and health profession knowledge. Participants demonstrated significant improvement in activity, knowledge, and perceptions of physical and mental function, and appreciated the guided, group sessions. Students completed an interprofessional readiness questionnaire and reported significant improvement in the understanding of the benefits of interprofessional education and of their role in health care. This program provides evidence of the dual benefit that occurs from the delivery of a student-assisted, interprofessional men’s health program to at-risk community members

Benefits and Success of an Interdisciplinary Wellness Interest Group (iWIG) at a Modern Jesuit University

Aim: To highlight the early achievements and discuss the benefits of forming an Interdisciplinary Wellness Interest Group (iWIG) on a modern Jesuit University campus. Background: While wellness programs have a place in academic communities, universal perspectives on the best way to lead Wellness initiatives is lacking. An iWIG gives a common platform to share ideas, communicate across audiences, and provide important information to the campus community about health promotion and health patterns of the campus community. Methods: After assembling the iWIG team, on-campus meetings were held with members of the interdisciplinary group. These meetings include faculty, staff, and students from various departments. The iWIG continues to meet regularly to expand and develop wellness initiatives, research opportunities and to ensure a presence on campus. Results: The iWIG has impacted many initiatives on campus, a select few which are profiled in this manuscript. The group is involved in funded research studies, has received a Healthy Workplace designation, and continues to expand health and wellness into various departments on campus. Conclusions: The interdisciplinary group has provided those with an interest in health and wellness with a formal platform to express ideas and implement initiatives for all individuals to better the overall well-being of the university community

Factors influencing decision making in neonatology: inhaled nitric oxide in preterm infants.

ObjectiveWe studied decision making regarding inhaled nitric oxide (iNO) in preterm infants with Pulmonary Hypertension (PH).Study designWe asked members of the AAP-Society of Neonatal-Perinatal Medicine and Division-Chiefs to select from three management options- initiate iNO, engage parents in shared decision making or not consider iNO in an extremely preterm with PH followed by rating of factors influencing their decision.ResultsThree hundred and four respondents (9%) completed the survey; 36.5% chose to initiate iNO, 42% to engage parents, and 21.5% did not consider iNO. Provider's prior experience, safety, and patient-centered care were rated higher by those who initiated or offered iNO; lack of effectiveness and cost considerations by participants who did not chose iNO.ConclusionsMost neonatologists offer or initiate iNO therapy based on their individual experience. The minority who chose not to consider iNO placed higher value on lack of effectiveness and cost. These results demonstrate a tension between evidence and pathophysiology-based-therapy/personal experience

Validation of a Single Inertial Sensor for Measuring Running Kinematics Overground During a Prolonged Run

This article is made available in accordance with the publisher's statement on Open access.Introduction: The purpose of this study was to validate acceleration data from a single inertial sensor containinga tri-axial accelerometer, whilst running overground during a prolonged run against a motion analysis system. Methods: An inertial sensor was placed on the low back of 10 runners who performed an 8 km run on a treadmill.To provide validation of the sensor, data were collected as runners ran along a runway through a motion analysis system at the beginning and throughout the run.Results: High levels of agreement between the two systems were found in the craniocaudal and mediolateral acceleration, with antero posterior having the least agreement with greatest Typical Error of the Estimate (0.66 sample points). Very high to extremely high correlations across all testing times were found in all three directions of accelerations (r=0.75 to 0.95). Heel strike and toe off events were identified in anteroposterior and craniocaudal acceleration, with high levels of agreement and extremely high correlations (r=0.99) between the two systems.Minimal variation and change in agreement and correlation between the data at each testing time were found. Discussion: This study provides evidence that a single inertial sensor placed on the low back is valid for measuring three-dimensional acceleration in overground running during a prolonged run. Further analysis identified specific events of heel strike and toe off and were comparable between the two systems. The minimal variation and change in agreement between the two systems during the run indicates the adherence method of the inertial sensor was suitable. Conclusions: The results of this study indicate that data collected from a single inertial sensor is highly correlated with simultaneous data collected using a motion analysis system, and has the capability to identify heelstrike and toe off events in overground running throughout a prolonged fatiguing run

Pillow use: the behavior of cervical stiffness, headache and scapular/arm pain

Susan J Gordon1,2, Karen A Grimmer-Somers3, Patricia H Trott41Associate Professor, School of Public Health, Tropical Medicine and Rehabilitation Sciences, James Cook University, Townsville, Australia; 2Member, International Centre for Allied Health Evidence, University of South Australia, Australia; 3Professor of Allied Health, School of Health Sciences, University of South Australia, Director, International Centre for Allied Health Evidence, University of South Australia, Australia; 4Associate Professor, School of Health Sciences, University of South AustraliaBackground: Pillows are intended to support the head and neck in a neutral position to minimize biomechanical stresses on cervical structures whilst sleeping. Biomechanical stresses are associated with waking cervical symptoms. This paper adds to the scant body of research investigating whether different pillow types produce different types and frequencies of waking symptoms in asymptomatic subjects.Methods: A random-allocation block-design blinded field trial was conducted in a large South Australian regional town. Subjects were side-sleepers using one pillow only, and not receiving treatment for cervicothoracic problems. Waking cervical stiffness, headache and scapular/arm pain were recorded daily. Five experimental pillows (polyester, foam regular, foam contour, feather, and latex) were each trialed for a week. Subjects&amp;rsquo; &amp;lsquo;own&amp;rsquo; pillow was the control (a baseline week, and a washout week between each experimental pillow trial week). Subjects reported waking symptoms related to known factors (other than the pillow), and subjects could &amp;lsquo;drop out&amp;rsquo; of any trial pillow week.Results: Disturbed sleep unrelated to the pillow was common. Waking symptoms occurring at least once in the baseline week were reported by approximately 20% of the subjects on their &amp;lsquo;own&amp;rsquo; pillow. The feather trial pillow performed least well, producing the highest frequency of waking symptoms, while the latex pillow performed best. The greatest number of &amp;lsquo;drop outs&amp;rsquo; occurred on the feather pillow. The foam contour pillow performed no better than the foam regular pillow.Conclusion: &amp;lsquo;Own&amp;rsquo; pillows did not guarantee symptom-free waking, and thus were a questionable control. The trial pillows had different waking symptom profiles. Latex pillows can be recommended over any other type for control of waking headache and scapular/arm pain.Keywords: pillow type, cervical stiffness, arm pain, headach
