The Usefulness of Submaximal Exercise Gas Exchange in Pulmonary Arterial Hypertension: A Case Series
Authors: Woods Paul R. , Frantz Robert P. , Johnson Bruce D.
Published: September 2017

Introduction

Submaximal exercise gas exchange may be a useful tool to track responses to therapy in pulmonary arterial hypertension (PAH) patients.

Methods

Three patients diagnosed with idiopathic PAH, on differing therapies, were included. Standard clinical tests (echocardiography; 6 minute walk) were performed pre and 3-5 months after treatment. Gas exchange was measured during 3 minutes of step exercise at both time points.

Results

Gas exchange variables, end tidal CO2 (PETCO2) and the ratio of ventilation to CO2 production (VE/VCO2), during submaximal exercise were able to track patient responses to therapy over a 3-5 month period. Two patients demonstrated positive improvements, with an increased PETCO2 and decreased VE/VCO2 during light exercise, in response to an altered therapeutic regime. The third patient had a worsening of gas exchange (decreased PETCO2 and increased VE/VCO2) following no changes in the medical regime from the baseline visit.

Conclusion

Gas exchange variables measured during light submaximal exercise, such as PETCO2 and VE/VCO2, may be able to better detect small changes in functional status following treatment and could, therefore, be a useful tool to track disease severity in PAH patients. Further study is required to determine the clinical usefulness of these gas exchange variables.

Conjoined twins are identical twins that have incompletely separated in utero. The prognosis for conjoined twins is poor and management in a skilled tertiary care centre is paramount for definitive care. We describe our experience with a telemedical consultation on conjoined twins in The Dominican Republic from our eHealth centre in Valhalla, NY. The patients were two month old, female, pygopagus conjoined twins. A multidisciplinary teleconference was initiated with the patients, their family, the referring paediatrician and our team. Based on this teleconsultation, the team felt as though the twins may be amenable to a surgical separation. They presented to our centre in Valhalla, NY, for a detailed physical examination and series of imaging studies. Soon after, the patients underwent a successful 21 h separation procedure and were discharged 12 weeks later. To our knowledge, this is one of the first reports of an international teleconsultation leading to a successful conjoined twin separation procedure.
Feasibility of using a video diary methodology with older African Americans living alone
Authors: Owens Otis L , Beer Jenay M , Revels Asa , Levkoff Sue
Published: September 2017

Objectives

The goal of this research was to determine whether video diary, a qualitative, self-recorded, video-ethnographic method, is feasible for use among older African Americans (AAs) who live alone. The research, which stems from a larger study on aging in place, focuses specifically on the pros and cons of the video diary and provides recommendations for improving the methodology.

Methods

Twelve participants were engaged in a 90-minute training on how to record videos using tablet computers, seven days of recording video diaries, and one in-person interview.

Results

While all participants reported being comfortable with using tablet computers to record video diaries, many participants expressed the need for additional training and assistance. In addition, video diaries recorded by participants commonly exhibited issues (e.g. framing, gaze, and audibility) that compromised video quality.

Discussion

Video diary may be an effective method for collecting information from older African Americans. However, some suggestions for improving this methodology are providing in-depth video diary and additional camera training, establishing multiple points of contact for technical support, and providing male participants with additional practice.
In comparative perspective: The effects of incarceration abroad on penal subjectivity among prisoners in Lithuania
Authors: Slade Gavin , Vaičiūnienė Rūta
Published: September 2017

This article looks at how global flows of people and policies affect penal subjectivity among prisoners in Lithuania. Those who had previously been incarcerated abroad perceive their punishment in Lithuania’s reforming penal system in comparative terms. We find that international prison experience may either diminish or increase the sense of the severity of the current punishment. Respondents often felt more comfortable in a familiar culture of punishment in Lithuania that emphasizes autonomy and communality. Moreover, internationalized prisoners perceive prison reform emulating West European models as a threat to this culture and are able to articulate comparative critiques of this reform and contest its effects.
“A Bridge Between High School and College”
Authors: Lane Tonisha B. , Morgan Kali , Lopez Megan M.
Published: September 2017

Underserved students express a high interest in earning a science, technology, engineering, and mathematics (STEM) degree. However, their ACT benchmark indicators tend to be much lower than their peers, especially for students who report more than one underserved attribute. There are a number of STEM intervention programs (SIPs) that are designed to retain and graduate underserved students in STEM. Yet, relatively few engage in theoretically driven, empirical research to elucidate what program components contribute to college readiness. Using Conley’s college and career readiness framework, this qualitative case study examined how one SIP helped underserved students overcome academic barriers and acquire context-specific knowledge. Findings revealed that nine interrelated practices and activities contributed to students feeling better prepared for the STEM curriculum and college expectations. Still, more attention could have been devoted to advancing key cognitive strategies. This article concludes with practical implications for SIP program administrators and faculty.
Developing Health Promotion Strategies to Enhance Clinical Practice Considering Risk Factors for Age-Related Hearing Loss
Authors: Ramkissoon Ishara , Buchanan Kathryn R.
Published: September 2017

Health care professionals including physicians, nurses, and audiologists are charged with providing comprehensive geriatric care for millions of aging adults. As baby boomers mature, prevalence of age-related hearing loss (ARHL) among adults aged 45+ years has risen from 30% to 50%. New findings have emerged regarding risk factors affecting ARHL prevalence. Many aging adults have medical comorbidities, such as diabetes, cardiovascular disease, and hypertension, which substantially increase the risk for ARHL. Recent studies highlighted links between cognitive skills, psychological health, and lifestyle choices like exercise and smoking that also relate to hearing loss. Thus, both intrinsic and extrinsic factors influence risk for ARHL. However, many practitioners are unaware of the relationship between such risk factors and ARHL. Therefore, this tutorial article highlights key research findings and summarizes current knowledge for clinical application. Specific audiologic and interdisciplinary strategies for clinical intervention are recommended within a framework of developing community-specific hearing health promotion programs.
Cyclin D2 is a critical mediator of exercise-induced cardiac hypertrophy
Authors: Luckey Stephen W , Haines Chris D , Konhilas John P , Luczak Elizabeth D , Messmer-Kratzsch Antke , Leinwand Leslie A
Published: September 2017

A number of signaling pathways underlying pathological cardiac hypertrophy have been identified. However, few studies have probed the functional significance of these signaling pathways in the context of exercise or physiological pathways. Exercise studies were performed on females from six different genetic mouse models that have been shown to exhibit alterations in pathological cardiac adaptation and hypertrophy. These include mice expressing constitutively active glycogen synthase kinase-3β (GSK-3βS9A), an inhibitor of CaMK II (AC3-I), both GSK-3βS9A and AC3-I (GSK-3βS9A/AC3-I), constitutively active Akt (myrAkt), mice deficient in MAPK/ERK kinase kinase-1 (MEKK1−/−), and mice deficient in cyclin D2 (cyclin D2−/−). Voluntary wheel running performance was similar to NTG littermates for five of the mouse lines. Exercise induced significant cardiac growth in all mouse models except the cyclin D2−/− mice. Cardiac function was not impacted in the cyclin D2−/− mice and studies using a phospho-antibody array identified six proteins with increased phosphorylation (greater than 150%) and nine proteins with decreased phosphorylation (greater than 33% decrease) in the hearts of exercised cyclin D2−/− mice compared to exercised NTG littermate controls. Our results demonstrate that unlike the other hypertrophic signaling molecules tested here, cyclin D2 is an important regulator of both pathologic and physiological hypertrophy.

Impact statement

This research is relevant as the hypertrophic signaling pathways tested here have only been characterized for their role in pathological hypertrophy, and not in the context of exercise or physiological hypertrophy. By using the same transgenic mouse lines utilized in previous studies, our findings provide a novel and important understanding for the role of these signaling pathways in physiological hypertrophy. We found that alterations in the signaling pathways tested here had no impact on exercise performance. Exercise induced cardiac growth in all of the transgenic mice except for the mice deficient in cyclin D2. In the cyclin D2 null mice, cardiac function was not impacted even though the hypertrophic response was blunted and a number of signaling pathways are differentially regulated by exercise. These data provide the field with an understanding that cyclin D2 is a key mediator of physiological hypertrophy.

Published: September 2017

Rationale

Stroke is a major cause of death and disability worldwide, yet 80% of strokes can be prevented through modifications of risk factors and lifestyle and by medication. While management strategies for primary stroke prevention in high cardiovascular disease risk individuals are well established, they are underutilized and existing practice of primary stroke prevention are inadequate. Behavioral interventions are emerging as highly promising strategies to improve cardiovascular disease risk factor management. Health Wellness Coaching is an innovative, patient-focused and cost-effective, multidimensional psychological intervention designed to motivate participants to adhere to recommended medication and lifestyle changes and has been shown to improve health and enhance well-being.

Aims and/or hypothesis

To determine the effectiveness of Health Wellness Coaching for primary stroke prevention in an ethnically diverse sample including Māori, Pacific Island, New Zealand European and Asian participants.

Design

A parallel, prospective, randomized, open-treatment, single-blinded end-point trial. Participants include 320 adults with absolute five-year cardiovascular disease risk ≥ 10%, calculated using the PREDICT web-based clinical tool. Randomization will be to Health Wellness Coaching or usual care groups. Participants randomized to Health Wellness Coaching will receive 15 coaching sessions over nine months.

Study outcomes

A substantial relative risk reduction of five-year cardiovascular disease risk at nine months post-randomization, which is defined as 10% relative risk reduction among those at moderate five-year cardiovascular disease risk (10–15%) and 25% among those at high risk (>15%).

Discussion

This clinical trial will determine whether Health Wellness Coaching is an effective intervention for reducing modifiable risk factors, and hence decrease the risk of stroke and cardiovascular disease.
Nation, Identity and Performance: The Spanish Zarzuela in Argentina, 1890–1900
Authors: McCleary Kristen
Published: September 2017

This article argues that the Spanish zarzuela, the most popular entertainment genre in Buenos Aires, Argentina in the 1890s, sowed the seeds of its own demise, precisely because of its success as an entertainment export. In the early 1890s, Buenos Aires’ audience members were eager for Spanish entertainment, but by the decade’s end they began to question the appropriateness of having Argentine character types performed by its former colonisers. Despite the fact that Spanish actors worked hard to integrate themselves with Argentine playwrights, helping Argentines to establish their own theatre industry, over time Argentine audiences began to demand entertainment that depicted their own nation and customs. Tensions over national identity reached a peak as a result of the Cuban independence movement of 1895–98. Zarzuela performers were visible and vulnerable symbols of Spanish colonisation during its last moments as a colonial power on the stages of the Americas.
Oral teriflunomide in the treatment of relapsing forms of multiple sclerosis: clinical evidence and long-term experience
Authors: Miller Aaron E.
Published: September 2017

Key objectives in the treatment of multiple sclerosis (MS) include prevention of relapses, a reduction in the accumulation of disability and slowing of the brain volume loss that occurs from the earliest stages of the disease. Teriflunomide, a once-daily, oral immunomodulatory therapy, has demonstrated efficacy across multiple measures of disease activity and worsening in patients with relapsing forms of MS and in those with a first clinical episode suggestive of MS. In this review, the latest evidence relating to the proposed mechanism of action of teriflunomide in MS is explored, including novel insights provided from the recently completed Teri-DYNAMIC study. Key clinical and magnetic resonance imaging data from the completed long-term extensions of the phase II and III (TEMSO, TOWER and TOPIC) studies are highlighted, and the long-term safety profile of teriflunomide, as evidenced by data from these extension studies, is presented. Although randomized clinical trials represent the highest level of evidence to support the use of therapeutic interventions, it is also important to understand the performance of a particular treatment in the real-world setting. In this regard, the results of the recently completed, global, phase IV Teri-PRO study are of particular interest and provide further insights into the benefits of teriflunomide treatment from the patient perspective. Collectively, the data presented in this review demonstrate a favorable benefit–risk profile for teriflunomide, thereby supporting its long-term use for the treatment of patients with relapsing forms of MS.
Effect of Expertise on Boundary Extension in Approach Sequences
Authors: Ménétrier Emmanuelle , Didierjean André , Robin Frédérique
Published: September 2017

In a constantly changing environment, one of the conditions for adaptation is based on the visual system’s ability to realize predictions. In this context, a question that arises is the evolution of the processes allowing anticipation with regard to the acquisition of knowledge relative to specific situations. We sought to study this question by focusing on boundary extension, the tendency to overestimate the scope of a previously perceived scene. We presented to novice, beginner, and expert car drivers road scenes in the form of approach sequences constituting very briefly displayed photographs (i.e., 250 milliseconds each), in order to determine the effect of expertise at an early stage of scene perception. After three presentations, participants had to judge whether a fourth photograph was the same, closer up, or further away than the third one. When experts and beginners showed a classical boundary extension effect, novices presented no directional memory distortion. Different hypotheses are discussed.
Genetic variations in the TLR3 locus are associated with eosinophilic esophagitis
Authors: Ávila-Castellano Robledo , García-Lozano José-Raúl , Cimbollek Stefan , Lucendo Alfredo J , Bozada Juan-Manuel , Quiralte Joaquín
Published: September 2017

Background

Eosinophilic esophagitis (EoE) is an antigen-driven disease mediated by an abnormal immune Th2 response.

Objective

The objective of this article is to investigate genes associated with regulating immune responses leading to disease susceptibility.

Methods

Twenty-seven tag single nucleotide polymorphisms (tSNPs) selected in five candidate genes ( TLR3, TLR4, FOXP3, FLG and TSLP) were genotyped in 218 EoE patients and 376 controls. Skin prick tests were carried out in EoE patients with a panel of 17 aeroallergens and 22 plant- and animal-derived foods.

Results

Five tSNPs located in the TSLP locus and one tSNP located in the TLR3 locus were significantly associated with EoE. The interactions between TLR3 and TSLP loci were analyzed. TLR3+/TSLP– and TLR3–/TSLP+ individuals showed a significantly reduced susceptibility to EoE compared to TLR3–/TSLP– individuals (OR = 0.66, p = 0.036 and OR = 0.23, p = 0.00014, respectively). Likewise, TLR3+/TSLP+ individuals showed the most decreased susceptibility of developing EoE (OR = 0.16, p = 0.0001). However, the interaction gain attributed to the combination of both genes was negative (IG = –4.52%), which indicated redundancy or independent effect. Additionally, TLR3 locus was found to be associated with aeroallergen and food sensitization in EoE patients (OR = 9.67, pc = 0.025 and OR = 0.53, pc = 0.048, respectively).

Conclusion

TLR3 constitutes a novel genetic susceptibility locus for developing EoE, and the effects would be independent of TSLP.
Quantitative characterization of optic nerve atrophy in patients with multiple sclerosis
Authors: Harrigan Robert L , Smith Alex K , Lyttle Bailey , Box Bailey , Landman Bennett A , Bagnato Francesca , Pawate Siddharama , Smith Seth A
Published: September 2017

Background

Optic neuritis (ON) is one of the most common presentations of multiple sclerosis (MS). Magnetic resonance imaging (MRI) of the optic nerves is challenging because of retrobulbar motion, orbital fat and susceptibility artifacts from maxillary sinuses; therefore, axonal loss is investigated with the surrogate measure of a single heuristically defined point along the nerve as opposed to volumetric investigation.

Objective

The objective of this paper is to derive optic nerve volumetrics along the entire nerve length in patients with MS and healthy controls in vivo using high-resolution, clinically viable MRI.

Methods

An advanced, isotropic T2-weighted turbo spin echo MRI was applied to 29 MS patients with (14 patients ON+) or without (15 patients ON–) history of ON and 42 healthy volunteers. An automated tool was used to estimate and compare whole optic nerve and surrounding cerebrospinal fluid radii along the length of the nerve.

Results and conclusion

Only ON+ MS patients had a significantly reduced optic nerve radius compared to healthy controls in the central segment of the optic nerve. Using clinically available MRI methods, we show and quantify ON volume loss for the first time in MS patients.
The Lymphatic System: The Achilles Heel of the Fontan-Kreutzer Circulation
Authors: Kreutzer Christian , Kreutzer Guillermo
Published: September 2017

In spite of excellent long term survival the Fontan Kreutzer procedure commonly presents late failure due to end-organ damage. Several advances have been described to refine single ventricle management and surgical techniques. However, very little research has been dedicated to the lymphatic circulation in the precarious Fontan hemodynamic state. The lymphatic circulation is clearly affected since there is increased lymph production, which requires to be drained at a similar or higher pressure than it is produced, commonly resulting in chronic lymphedema. Chronic lymphedema induces fibrosis and end-organ failure even in normal circulation. Diverting lymph drainage to the low-pressured systemic atrium in Fontan may represent a valid alternative for the treatment of devastating complications as protein-losing enteropathy and plastic bronchitis and may prevent or decrease the development of end-organ fibrosis or failure.

Published: September 2017

We adopted a grounded theory approach to explore the process of recovery experienced by stroke survivors over the longer term who were living in the community in the United Kingdom, and the interacting factors that are understood to have shaped their recovery trajectories. We used a combination of qualitative methods. From the accounts of 22 purposively sampled stroke survivors, four different recovery trajectories were evident: (a) meaningful recovery, (b) cycles of recovery and decline, (c) ongoing disruption, (d) gradual, ongoing decline. Building on the concept of the illness trajectory, our findings demonstrate how multiple, interacting factors shape the process and meaning of recovery over time. Such factors included conception of recovery and meanings given to the changing self, the meanings and consequences of health and illness experiences across the life course, loss, sense of agency, and enacting relationships. Awareness of the process of recovery will help professionals better support stroke survivors.

Authors: Wajda Benjamin G. , Platt Alexander S. , Ingram April D. , Ells Anna L.
Published: September 2017

We describe the retinal manifestations of a patient with a unique mutation of the Regulator of telomere length 1 ( RTEL1) gene resulting in dyskeratosis congenita (DC), a rare, fatal, inherited disease. A 4-year-old boy with DC was referred for ophthalmology consult by his attending hematologist and underwent a complete ophthalmic examination, including wide-field fundus imaging and fluorescein angiography. The patient was found to have bilateral retinal vasculopathy and extensive microvascular abnormalities in addition to avascular regions in the temporal peripheral retina. He received multiple pan-retinal photocoagulation treatments in both eyes. Our case highlights the importance of ophthalmic screening and fluorescein angiography and the potential need for timely laser photocoagulation for sight-threatening retinopathy in patients with DC.

Authors: Cross Shane P.M. , Scott Jan , Hickie Ian B.
Published: September 2017

Background

Transition from at-risk state to full syndromal mental disorders is underexplored for unipolar and bipolar disorders compared with psychosis.

Aims

Prospective, trans-diagnostic study of rates and predictors of early transition from sub-threshold to full syndromal mental disorder.

Method

One-year outcome of 243 consenting youth aged 15–25 years with a sub-syndromal presentation of a potentially severe mental disorder. Survival analysis and odds ratio (OR) for predictors of transition identified from baseline clinical and demographic ratings.

Results

About 17% (n=36) experienced transition to a major mental disorder. Independent of syndromal diagnosis, transition was significantly more likely in individuals who were NEET (not in education, employment or training), in females and in those with more negative psychological symptoms (e.g. social withdrawal).

Conclusions

NEET status and negative symptoms are modifiable predictors of illness trajectory across diagnostic categories and are not specific to transition to psychosis.

Published: September 2017

Despite many studies on infrastructure resilience in the existing literature, there is a limited empirical understanding of disaster resilience in the context of intermittent infrastructure systems. To fill this knowledge gap, our study provides an example assessment of the resilience of Kathmandu Valley's electricity and water supply infrastructure systems in the 2015 Gorkha earthquake. The study is based on qualitative data collected over a period of one year following the earthquake, obtained through in-depth interviews (n = 52), a focus group, and a review of secondary sources. A resilience assessment framework that includes eight factors adapted from existing studies—vulnerability, anticipation, redundancy, adaptive capacity, rapidity, resourcefulness, cross-scale interactions, and learning culture—was used for the data analysis. The characteristics of intermittent infrastructure systems pertaining to resilience identified in this study could have important implications for engineers and decision makers in developing communities to better design and maintain infrastructure in the face of disasters.

Resumo. No presente estudo procuramos entender o principal substrato de ocorrência de ninfas de Plecoptera (Insecta) em rios do Parque Estadual da Pedra Branca (Rio de Janeiro, RJ, Brasil). As coletadas das ninfas foram realizadas entre agosto/2008 a março/2009, em cinco riachos localizados a 200 m de altitude. Foram investigados cinco tipos diferentes de substrato: areia, folhiço retido, folhiço de fundo, rocha com musgo e rocha solta lisa. Além da coleta de imaturos, a temperatura da água e do ar, o pH, a largura e a profundidade dos riachos, e a velocidade da água (método de flutuação) foram medidas. A Análise de Espécies Indicadoras e o Teste de Monte Carlo foram utilizados para determinar a preferência de habitats pelas morfoespécies. O índice de Shannon foi utilizado para verificar a maior diversidade entre os substratos e os rios. Uma análise de agrupamento foi realizada a fim de verificar a similaridade física e biológica dos rios. Um total de 559 ninfas foi coletado e distribuídos em seis morfoespécies. O substrato ‘folhiço retido’ mostrou-se como o de maior abundância e riqueza em todos os riachos estudados. A heterogeneidade de substratos foi apontada como principal fator de diversidade entre os pontos de coleta.Diversity and substrate distribution of Plecoptera nymphs (Insecta) in strems of Parque Estadual da Pedra Branca, Rio de Janeiro, BrazilAbstract. The present study contributes to the understanding the main substrate where Plecoptera nymphs have occur in streams of Parque Estadual da Pedra Branca (Rio de Janeiro municipality, Rio de Janeiro State, Brazil). The collects of the nymphs were realized between August 2008 to March 2009, in five streams located at 200 m. asl. Five different substrates were investigated: sand, litter deposited in pool areas, litter in riffle areas, stones with moss and free stones. In addition to the collection of nymphs, water and air temperatures, pH, width and depth of the streams, and water velocity (float method) were measurement. The Indicator Species Analyses and Monte Carlo Test were used to determine the habitat distributions of the insects. The Shannon Index was used to verify the diversity index of streams and substrates. The Cluster Analysis using the similarity index of Morisita, was used to verify the physical and biological similarity of the streams studied. A total of 559 nymphs were collected and distributed by six taxa. The litter was the substrate with high abundance and diversity. The heterogeneity of substrates maybe the factor to explain the diversity between the areas collected.

O objetivo deste estudo foi conhecer a diferença da termorregulação de colônias de Melipona eburnea Friese. As observações foram realizadas en­tre 09 de junho e 09 de julho de 2016, 24 horas por dia, utilizando-se dois ninhos de M. eburnea, um em caixa racional e outro em troncode árvore. Utilizou-se Data Logger(modelo HOBO U12 – 012), com exatidão de ±0,35 °C. Verificou-se que o ninho de M. eburnea em oco de árvore manteve uma temperatura média de 31,7 ºC, enquanto que o ninho em caixa racional apresentou temperatura média de 27,8 ºC. A temperatura ambiente variou de 16,6 a 34,2 °C, com média de 23,8 ºC. A espécie M. eburnea em caixa racional apresentou termorregulação inferior à colônia em oco de árvore e também maior oscilação de temperatura. Concluiu-se que M. eburnea mantém sua colônia em homeostase, mesmo quando há variações na temperatura ambiente (ninho em oco de árvore). M. eburnea apresentou termorregulação insatisfatória, quando mantida em caixa racional.Thermoregulation in colonies of Melipona eburnea Friese(Apidae: Meliponina) rationally bred in Rio Branco, AcreAbstract. Temperature is the climatic agent that most directly affects the metabolism of bees, influencing at the development of the young being able lead to negative results for honey production. The objective of this study was to know the difference of thermoregulation of Melipona eburnea Friese colonies. The observations were made between June 9 and July 9, 2016, 24 hours a day, using two nests of M. eburnea, one in rational box and the other in tree trunk. Was used Data Logger (model HOBO U12-012) was used, with accuracy of ± 0.35 °C. Was verified that the nest of M. eburnea in tree hollow maintained an average temperature of 31.7 ºC, whereas the that nest in rational box presented average temperature of 27.8 ºC. The ambient temperature ranged from 16.6 to 34.2 ºC, with a mean of 23.8 °C. The species M. eburnea in rational box presented inferior thermoregulation to the colony in tree hollow and also greater temperature oscillation. It was concluded that M. eburnea maintains its colony in homeostasis, even when there are variations in the ambient temperature (nest in hollow tree). M. eburnea presented unsatisfactory thermoregulation when kept in rational box.

The objective of this study was to measure internal medicine resident engagement with an electronic medical record‐based dashboard providing feedback on their use of routine laboratory tests relative to service averages. From January 2016 to June 2016, residents were e‐mailed a snapshot of their personalized dashboard, a link to the online dashboard, and text summarizing the resident and service utilization averages. We measured resident engagement using e‐mail read‐receipts and web‐based tracking. We also conducted 3 hour‐long focus groups with residents. Using grounded theory approach, the transcripts were analyzed for common themes focusing on barriers and facilitators of dashboard use. Among 80 residents, 74% opened the e‐mail containing a link to the dashboard and 21% accessed the dashboard itself. We did not observe a statistically significant difference in routine laboratory ordering by dashboard use, although residents who opened the link to the dashboard ordered 0.26 fewer labs per doctor‐patient‐day than those who did not (95% confidence interval, –0.77 to 0.25; P = 0.31). While they raised several concerns, focus group participants had positive attitudes toward receiving individualized feedback delivered in real time.

Common farm poisons: part 1
Authors: Bates Nicola , Payne Jo
Published: September 2017

Numerous hazardous chemicals are present on farms including pesticides, fertilizers and disinfectants. This article discusses the toxic effects and treatment of farm animals exposed to nitrates, urea, metaldehyde, anticoagulant rodenticides and phenolic compounds in asphalt, clay pigeons and creosote. Nitrate poisoning results in methaemoglobinaemia and urea can cause ammonia toxicosis, particularly in cattle. The molluscicide metaldehyde causes seizures which can be rapid in onset. Anticoagulant rodenticides produce coagulopathy and haemorrhage which can manifest in a variety of ways since bleeding can occur anywhere. Pigs are particularly susceptible to poisoning with phenolic compounds which typically presents as liver necrosis. The severity and susceptibility of poisoning in farm animals varies with species and duration of exposure. Although some poisons, such as anticoagulant rodenticides and nitrates, have specific antidotes, vitamin K1 and methylene blue (methylthioninium chloride), respectively, treatment is generally supportive with identification and removal of the source and management of clinical signs.
Lameness — preventative management strategies
Authors: Page Phillipa , Lovatt Fiona
Published: September 2017

Sheep lameness is a widespread health issue affecting most flocks within the UK. The authors consider that flock levels above 2% are significant in terms of production losses and challenges with control. Concern for sheep welfare, losses in production of the flock and the associated costs of a lameness problem are some of the reasons for a farmer contacting their veterinary surgeon for help and advice.

This article focuses on the common infectious causes of sheep lameness: scald, footrot and contagious ovine digital dermatitis (CODD). It seeks to provide the most up to date research surrounding the aetiology of these diseases and treatments. Defining the risk factors for lameness on a farm is an important aspect when developing a preventative management strategy for the control of lameness. These risk factors will be discussed. The 5-Point Plan is an industry wide recognised plan for controlling lameness. How to implement this plan on farm including the use of vaccination and good practice quarantine procedures will be described in this article.
