Weather-wise? Sporting embodiment, weather work and weather learning in running and triathlon
Authors: Allen-Collinson Jacquelyn , Jennings George , Vaittinen Anu , Owton Helen
Published: March 2018

Weather experiences are currently surprisingly under-explored and under-theorised in sociology and sport sociology, despite the importance of weather in both routine, everyday life and in recreational sporting and physical–cultural contexts. To address this lacuna, we examine here the lived experience of weather, including ‘weather work’ and ‘weather learning’, in our specific physical–cultural worlds of distance-running, triathlon and jogging in the United Kingdom. Drawing on a theoretical framework of phenomenological sociology, and the findings from five separate auto/ethnographic projects, we explore the ‘weather-worlds’ and weather work involved in our physical–cultural engagement. In so doing, we address ongoing sport sociological concerns about embodiment and somatic, sensory learning and ways of knowing. We highlight how weather work provides a key example of the phenomenological conceptualisation of the mind–body–world nexus in action, with key findings delineating weather learning across the meteorological seasons that contour our British weather-related training.
“It Is Not Natural Anymore”: Nutrition, Urbanization, and Indigenous Identity on Bolivia’s Andean Plateau
Authors: Lipus Adam C. , Leon Juan S. , Calle Susana C. , Andes Karen L.
Published: March 2018

The objective of this article was to characterize how urbanization and indigenous identity shape nutrition attitudes and practices in El Alto, a rapidly urbanizing and predominantly indigenous (Aymara) community on Bolivia’s Andean plateau. We took a qualitative ethnographic approach, interviewing health care providers ( n = 11) and conducting focus groups with mothers of young children ( n = 4 focus groups with 25 mothers total [age = 18–43 years, 60% Aymara]). Participants generally described their urban environment as being problematic for nutrition, a place where unhealthy “junk foods” and “chemicals” have supplanted healthy, “natural,” “indigenous” foods from the countryside. Placing nutrition in El Alto within a broader context of cultural identity and a struggle to harmonize different lifestyles and worldviews, we propose how an intercultural framework for nutrition can harmonize Western scientific perspectives with rural and indigenous food culture.

Substance use is prevalent among youth in postconflict African countries and is associated with a number of public health problems such as poverty, child homelessness, and school truancy. This qualitative study explores the risk factors associated with substance use among Liberian youth from the perspective of public-school students. Nine focus groups were conducted with 72 Liberian public-school students (35 female, 37 male). Multiple risk factors for substance use among Liberian youth were identified through qualitative analysis, including emotional instability, gender, fear of academic failure, accessibility to substances within the school and community, poverty, and unintentional drug use. These findings are important to public health campaigns and postconflict recovery in Liberia, and may also inform prevention programs for substance use among Liberian youth.
Potassium Channel Gain of Function in Epilepsy: An Unresolved Paradox
Authors: Niday Zachary , Tzingounis Anastasios V.
Published: March 2018

Exome and targeted sequencing have revolutionized clinical diagnosis. This has been particularly striking in epilepsy and neurodevelopmental disorders, for which new genes or new variants of preexisting candidate genes are being continuously identified at increasing rates every year. A surprising finding of these efforts is the recognition that gain of function potassium channel variants are actually associated with certain types of epilepsy, such as malignant migrating partial seizures of infancy or early-onset epileptic encephalopathy. This development has been difficult to understand as traditionally potassium channel loss-of-function, not gain-of-function, has been associated with hyperexcitability disorders. In this article, we describe the current state of the field regarding the gain-of-function potassium channel variants associated with epilepsy (KCNA2, KCNB1, KCND2, KCNH1, KCNH5, KCNJ10, KCNMA1, KCNQ2, KCNQ3, and KCNT1) and speculate on the possible cellular mechanisms behind the development of seizures and epilepsy in these patients. Understanding how potassium channel gain-of-function leads to epilepsy will provide new insights into the inner working of neural circuits and aid in developing new therapies.
Commentary on Katz’s Bystander Training as Leadership Training
Authors: Coker Ann L.
Published: March 2018

This response to Katz’s commentary is based on our team’s experiences and findings in bystander intervention design and evaluation among male and female adolescents in several high school settings. Three themes emerged in reflecting on “what worked” in our large evaluation in light of Katz’s commentary. First, our field needs data from multiple rigorous bystander intervention evaluations. Second, bystander interventions must be acceptable to the population receiving the intervention. Third, engaging all adolescent and young adults in prevention independent of sex or sexual orientation is essential to reduce sexual violence including harassment and bullying.

In this article, the author responds to three commentaries about his article “Bystander Training as Leadership Training: Notes on the Origins, Philosophy, and Pedagogy of the Mentors in Violence Prevention Model,” published in this volume. Topics covered in the commentaries and response include questions about evaluation and evidence for program effectiveness; the necessity for gender violence prevention education to be gender transformative and part of a comprehensive, multilevel prevention approach, especially for adolescents; and the degree to which Mentors in Violence Prevention (MVP), as a “social justice”–oriented program, incorporates intersectional and anti-oppression frameworks and perspectives.
Bystander Training as Leadership Training: Notes on the Origins, Philosophy, and Pedagogy of the Mentors in Violence Prevention Model
Authors: Katz Jackson
Published: March 2018

This article outlines the origins, philosophy, and pedagogy of the Mentors in Violence Prevention (MVP) program, which has played a significant role in the gender violence prevention field since its inception in 1993. MVP was one of the first large-scale programs to target men for prevention efforts, as well as the first to operate systematically in sports culture and the U.S. military. MVP also introduced the “bystander” approach to the field. MVP employs a social justice, gender-focused approach to prevention. Key features of this approach are described and contrasted with individualistic, events-based strategies that have proliferated on college campuses and elsewhere in recent years.
Reclaiming Gender and Power in Sexual Violence Prevention in Adolescence
Authors: Miller Elizabeth
Published: March 2018

The Mentors in Violence Prevention (MVP) model seeks to address the root causes of gender violence using a bystander approach and leadership training to challenge structures of patriarchy. Emerging research on adolescent relationship abuse and sexual violence points to key modifiable targets—transforming gender norms, addressing homophobia, integrating with comprehensive sexuality education, and acknowledging the needs of youth already exposed to violence. A social justice–based bystander approach such as the MVP model should be part of a multi-level approach to sexual violence prevention that addresses gender and power, encourages healthy sexuality conversations, and provides safety and support for survivors.
ClotAssist: A program to treat cancer-associated thrombosis in an outpatient pharmacy setting
Authors: Easaw Jacob C , McCall Susan , Azim Adrian
Published: March 2018

Stable cancer patients diagnosed with a pulmonary embolus or deep vein thrombosis are commonly referred to the emergency department for management. This practice strains an already overburdened emergency department and is associated with long wait times and poor disease/injection education for patients. This pilot study sought to determine if stable cancer patients with newly diagnosed cancer-associated thrombosis could be effectively managed by community-based pharmacists who followed an evidence-based protocol to prescribe and initiate low-molecular weight heparin therapy. We hypothesized that this novel care pathway could provide faster patient care with more comprehensive disease education, self-injection training, and follow-up. Fifty-five patients with various cancers, including gastroesophageal, urogenital, breast, brain, and lung were enrolled into this pilot study. We observed that this alternative first-dose treatment pathway provided safe and effective treatment of venous thromboembolism combined with excellent patient satisfaction. Following their interaction with the pharmacist, patients felt confident about their ability to self-inject and about their venous thromboembolism management overall. No occurrences of bleeding or other side-effects were observed. This pilot study demonstrates that community-based pharmacists are capable of delivering complex care services in the outpatient environment, particularly in the management of venous thromboembolism.
Stability of vincristine sulfate, doxorubicin hydrochloride and etoposide phosphate admixtures in polyisoprene elastomeric pump supporting transition of the EPOCH regimen to outpatient care

Published: March 2018

Background

The EPOCH regimen, consisting of vincristine sulfate, doxorubicin hydrochloride, and etoposide phosphate, is typically administered by continuous infusion over four days to oncology inpatients. If the EPOCH regimen was available to be administered through portable elastomeric pumps, chemotherapy could be transitioned to an outpatient setting, reducing inpatient bed days and overall healthcare costs. However, a lack of stability data for the admixtures in the elastomeric infusion devices currently prevents the transition of the regime to an outpatient setting. The purpose of this study is to determine the physical and chemical stability of the admixture in polyisoprene elastomeric pumps under different storage conditions to support the transition of the EPOCH regime to an outpatient setting.

Methods

The physico-chemical stability of three admixtures at a range of clinically relevant concentrations compounded in polyisoprene elastomeric infusors was determined when refrigerated at 2–6℃ over a 14-day period followed by 35℃ up to 7 days in the dark, and under standardized fluorescent light to simulate scenarios in clinical practice.

Results

All tested admixtures were compatible and the drugs were stable in the elastomeric infusors for up to 14 days when stored at 2–6℃ followed by 7 days at 35℃ in the dark, with nominal losses of <5%. The major degradant of etoposide phosphate was its active form etoposide. There was no degradation (<1% loss) found when the admixture was exposed to a standardized fluorescent light dose of 80 klux-h (25℃) for 10 h. The temperature and light conditions the infusors were exposed to during the stability study were more severe than the conditions determine during clinical administration.

Conclusion

The extended stability of the three infusional admixtures compounded in elastomeric infusion pumps demonstrated herein permits advance preparation and storage of these drugs, reducing pharmacy compounding resources. The demonstrated stability at 35℃ and under light exposure, conditions more severe than those experienced during clinical practice, support continuous infusions for up to seven days from the elastomeric infusors without a loss of potency. The proven stability of the EPOCH regimens in the tested elastomeric infusion device supports the transition of treatment to an outpatient setting which will reduce inpatient bed days and overall healthcare costs.

Authors: Martin Christina A. , Hiscock Harriet , Rinehart Nicole , Heussler Helen S. , Hyde Christian , Fuller-Tyszkiewicz Matthew , McGillivray Jane , Austin David W. , Chalmers Alexa , Sciberras Emma
Published: March 2018

Objective: To determine whether self-reported sleep hygiene practices are associated with self- and parent-reported behavioral sleep problems in adolescents with ADHD. Method: Participants included 79 adolescents with ADHD (13-17 years) and their parents. Adolescents were asked to report on their sleep hygiene (Adolescent Sleep Hygiene Scale) and sleep (Adolescent Sleep Wake Scale). Parents also reported on their adolescent’s sleep (Sleep Disturbance Scale for Children). Results: Poorer sleep hygiene was associated with higher total self-reported behavioral sleep problems and most self-reported sleep problems: falling asleep, reinitiating sleep, and returning to wakefulness. The association was also apparent for total parent-reported behavioral sleep problems, problems with initiating and maintaining sleep, and excessive somnolence. Conclusion: This study demonstrates small-to-moderate relationships between poor sleep hygiene practices and sleep problems in adolescents with ADHD, by both self- and parent-report.

Authors: Jordan Jeffrey W. , Stalgaitis Carolyn A. , Charles John , Madden Patrick A. , Radhakrishnan Anjana G. , Saggese Daniel
Published: March 2018

Purpose. Peer crowds are macro-level subcultures that share similarities across geographic areas. Over the past decade, dozens of studies have explored the association between adolescent peer crowds and risk behaviors, and how they can inform public health efforts. However, despite the interest, researchers have not yet reported on crowd size and risk levels from a representative sample, making it difficult for practitioners to apply peer crowd science to interventions. The current study reports findings from the first statewide representative sample of adolescent peer crowd identification and health behaviors. Methods. Weighted data were analyzed from the 2015 Virginia Youth Survey of Health Behaviors ( n = 4,367). Peer crowds were measured via the I-Base Survey™, a photo-based peer crowd survey instrument. Frequencies and confidence intervals of select behaviors including tobacco use, substance use, nutrition, physical activity, and violence were examined to identify high- and low-risk crowds. Logistic regression was used to calculate adjusted odds ratios for each crowd and behavior. Results. Risky behaviors clustered in two peer crowds. Hip Hop crowd identification was associated with substance use, violence, and some depression and suicidal behaviors. Alternative crowd identification was associated with increased risk for some substance use behaviors, depression and suicide, bullying, physical inactivity, and obesity. Mainstream and, to a lesser extent, Popular, identities were associated with decreased risk for most behaviors. Conclusions. Findings from the first representative study of peer crowds and adolescent behavior identify two high-risk groups, providing critical insights for practitioners seeking to maximize public health interventions by targeting high-risk crowds.
Pain and Masculinity: A Cohort Comparison between Mexican American Vietnam and Post–9/11 Combat Veterans
Authors: Cancio Roberto
Published: March 2018

Using twenty-six interviews with Mexican American veterans, this study analyzes cohort effects between Vietnam War veterans to Iraq and/or Afghanistan veterans on the meanings and experiences of pain from combat, masculinity, and how ethnicity affects expressions of pain. Although there were relative similarities between the cohorts, differences arose because of age. Vietnam veterans understood their pain to be long-lasting and have built coping mechanisms around a lifetime of pain, as opposed to younger veterans who have not yet solidified coping strategies. Machismo plays a dynamic part in the expression and daily experience with pain for young veterans, as opposed to older veterans who enjoy relaxed gendered obligations based on their age. Finally, older veterans used family as a base of social support, as opposed to younger veterans who found support from peer-mentor programs. In addition, respondents indicated that machismo acted more as guiding principle and offered them motivations to seek help, and not necessarily barriers to health. Overall, both cohorts are governed by strict gender standards and expressions influenced by their ethnic identity. Findings suggest that the study of race/ethnicity and age plays a fundamental framework from which to understand the experiences and behaviors of pain.
Black Masculinities on Trial in Absentia: The Case of Oscar Pistorius in South Africa
Authors: Langa Malose , Kirsten Adele , Bowman Brett , Eagle Gill , Kiguwa Peace
Published: March 2018

This article explores the social representation of black masculinities as violent in the globally publicized case of the murder by Oscar Pistorius of his girlfriend, Reeva Steenkamp. This murder and the subsequent media interest it generated highlighted the manner in which fear of crime in South Africa, particularly amongst certain sectors of the population such as white, male gun owners and gun lobbyists, (including Pistorius and his family members) contributed to assertions about their right to own guns to defend their families and possessions against this perceived threat. Such claims were made despite statistical evidence showing that black South Africans are more likely to be victims of violent crime than white South Africans. Drawing upon media coverage of the trial, this article critically discusses the intersection between masculinity and racial identity with a particular focus on gun ownership as a symbol of hegemonic white manhood, and the parallel construction of black masculinities as violent and dangerous. The Oscar Pistorius trial offers rich material for this analysis: his entire defence was based on the view that the intruder he feared was almost certainly a black man who, as a legitimate target for the use of lethal force in self-defence, deserved to die from the four bullets fired through a closed door. It is argued that in his absence, the black man was ever-present at the Oscar Pistorius trial as a threatening figure whose calling into being was revealing of how black masculinities continue to be represented, relayed and received in particular ways in post-apartheid South Africa.
Detection of feline coronavirus mutations in paraffin-embedded tissues in cats with feline infectious peritonitis and controls

Published: March 2018

Objectives

The amino acid substitutions M1058L and S1060A in the spike protein of feline coronavirus (FCoV) have been postulated to be responsible for the development of the pathogenic feline infectious peritonitis virus (FIPV), which causes feline infectious peritonitis (FIP). The aim of the following study was to investigate the presence of mutated virus in tissue samples of cats with and without FIP.

Methods

The study population consisted of 64 cats, 34 of which were diagnosed with FIP and 30 control cats. All cases underwent autopsy, histopathology and immunohistochemistry (IHC) for FCoV. Furthermore, a genotype-discriminating quantitative reverse transcriptase PCR (RT-qPCR) was performed on shavings of paraffin-embedded tissues to discriminate between cats with FIP and controls, and the sensitivity and specificity of this discriminating RT-qPCR were calculated using 95% confidence intervals (CIs).

Results

Specificity of genotype-discriminating RT-qPCR was 100.0% (95% CI 88.4–100.0), and sensitivity was 70.6% (95% CI 52.5–84.9). In cats with FIP, 24/34 tested positive for FIPV. In samples of three control cats and in seven cats with FIP, FCoV was found, but genotyping was not possible owing to low FCoV RNA concentrations. Out of the positive samples, 23 showed the amino acid substitution M1058L in the spike protein and none the substitution S1060A. One sample in a cat with FIP revealed a mixed population of non-mutated FCoV and FIPV (mixed genotype). For one sample genotyping was not possible despite high viral load, and two samples were negative for FCoV.

Conclusions and relevance

As none of the control animals showed FCoV amino acid substitutions previously demonstrated in cats with FIP, it can be presumed that the substitution M1058L correlates with the presence of FIP. FCoV was detected in low concentration in tissues of control animals, confirming the ability of FCoV to spread systemically. The fact that no negative controls were included in the IHC protocol could potentially lead to an underestimation of the sensitivity of the RT-qPCR.
Is macular pigment optical density really involved in fixation preference?
Authors: Erkan Turan Kadriye , Cankaya Ali Bulent , Taylan Sekeroglu Hande , Inam Onur , Karahan Sevilay
Published: March 2018

Purpose:

To evaluate macular pigment optical density in healthy children and to compare the values with those of strabismic children with respect to fixation preference.

Methods:

The study recruited 54 healthy and 41 strabismic children. Two groups were matched in terms of gestational age, birth weight, and body mass index. All participants underwent complete ophthalmological evaluation and macular pigment optical density measurement and filled a self-reported food frequency questionnaire. Strabismic children were categorized according to fixation preference.

Results:

The mean age was 9.87 ± 2.39 years in healthy children and 9.07 ± 2.07 years in children with strabismus (p = 0.091). Mean macular pigment optical density was 0.23 ± 0.25 in healthy eyes and 0.25 ± 0.27 in non-preferred eyes of strabismic children (p = 0.964). Macular pigment optical density was significantly higher in preferred eyes of strabismic children (0.43 ± 0.34) compared to non-preferred eyes (p = 0.004) and healthy eyes (p = 0.001). There was a difference of macular pigment optical density between both eyes in patients with grades 1, 2, and 3 fixation preference, whereas patients with grade 4 preference had similar macular pigment optical density in both eyes (p = 0.008). There was a statistically significant positive correlation between macular pigment optical density in preferred eyes and body mass index (r = 0.354, p = 0.023).

Conclusion:

Preferred eyes of children with strabismus seem to have higher macular pigment optical density readings. This difference may emerge from the higher tendency of recognizing the flicker stimulus while preferred eye is under testing. Similar macular pigment optical density in healthy and non-preferred eyes and the fact that both lower than preferred eyes remain unexplained. It should be kept in mind that macular pigment optical density results should be carefully interpreted and macular pigment optical density in cases with strabismus should be further investigated.
Complications of cataract surgery in eyes filled with silicone oil
Authors: Kanclerz Piotr , Grzybowski Andrzej , Schwartz Stephen G , Lipowski Paweł
Published: March 2018

Introduction:

The aim of the study was to evaluate complications of cataract surgery in eyes filled with silicone oil.

Methods:

This retrospective, noncomparative, consecutive case series analyzed medical files of patients with eyes filled with silicone oil undergoing cataract surgery. Phacoemulsification with posterior chamber intraocular lens implantation was conducted with or without concurrent silicone oil removal.

Results:

In this study, 121 eyes of 120 patients were included. In 32 eyes (26.4%) with evident silicone oil microemulsification or silicone oil–associated open-angle glaucoma, silicone oil was removed prior to phacoemulsification through a pars plana incision and no cases of posterior capsular rupture occurred during the subsequent cataract surgery. In the remaining 89 eyes, phacoemulsification was performed with silicone oil in the vitreous cavity. In these eyes, the rate of posterior capsular rupture was 9/89 (10.1%) and the rate of silicone oil migration into the anterior chamber through an apparently intact posterior capsule was 5/89 (5.6%). In 94 eyes (77.7%), an intraocular lens was inserted into the capsular bag, in 3 eyes (2.5%) into the sulcus, and in 1 eye (0.8%) a transscleral suturing was performed.

Conclusions:

In this series, complications related to the silicone oil were not uncommon during cataract surgery. In the majority of patients without evident silicone oil microemulsification or silicone oil–associated open-angle glaucoma, cataract surgery and posterior chamber intraocular lens implantation were performed while leaving the silicone oil in place.
Long-term follow-up of cryopreserved amniotic membrane transplant during strabismus reoperations: Up 85 months’ follow-up

Published: March 2018

Purpose:

To evaluate the long-term effect of cryopreserved human amniotic membrane transplant during strabismus reoperations.

Methods:

A total of 15 patients with persistent strabismus were included in a prospective study to evaluate the effect of wrapping the extra-ocular muscles with cryopreserved amniotic membrane during strabismus reoperations. The study end-point was the last follow-up visit. A successful outcome was defined as 0–10∆ of horizontal tropia and 0–4∆ of vertical tropia, with no limitation of ductions exceeding −1. A cosmetically acceptable outcome was defined as a tropia of 0–15∆.

Results:

Maximum follow-up was 85 months (mean: 25.4 ± 25.5 months). At the last follow-up visit, a successful outcome was achieved in 46.7%, a cosmetically acceptable outcome was achieved in 66.7%, and the mean ocular deviation angles improved from 38.60 ± 14.63∆, preoperatively, to 10.6 ± 11.08∆. Motility limitation on the final follow-up visit exceeded −1 in only 4/180 muscles (2.2%).

Conclusion:

The effect of cryopreserved amniotic membrane transplantation on the success of strabismus reoperations was moderate in terms of ocular alignment. Its effect was more pronounced in terms of ocular motility. The latter better reflects the level of adhesions. No long-term complications were documented, denoting safety of cryopreserved amniotic membrane usage during strabismus reoperations.

Published: March 2018

Objective:

The clinical impact of central line bundle programs for central line–associated bloodstream infections has been well demonstrated in intensive care units. However, the experience of central line bundle programs in totally implantable venous access devices (ports) in pediatric-hematology patients was limited.

Methods:

A retrospective study was designed to compare and evaluate the clinical impact of implementing a central line bundle for a 2-year 5-month period, including 10 months of prebundle period, 11 months of central line bundle (that includes needleless split-septum devices), and finally 8 months of central line bundle period in which single-use prefilled flushing devices were added to the previous central line bundle.

Results:

During the prebundle period, the rate of 14.5 central line–associated bloodstream infections per 1000 CL-days had decreased to 5.49 CLABSIs per 1000 CL-days in the first bundle period. The incidence rate ratio with these two groups was 0.379, indicating a relative risk reduction of 62% ( p = 0.005). By the addition of single-use prefilled flushing devices to the first bundle program, the central line–associated bloodstream infection rate decreased to 2.63 per 1000 CL-days. Port removal rate due to central line–associated bloodstream infections was 0.46 per 1000 catheter days in the bundle period, which was significantly lower than in the prebundle period in which port removal rate was 4.5 per 1000 catheter days ( p < 0.001).

Conclusion:

Central line bundle programs were found to be effective in decreasing central line–associated bloodstream infection rates, improving patients’ quality of life by preventing ports removal due in pediatric cancer patients.
Placement issues of hemodialysis catheters with pre-existing central lines and catheters
Authors: Aurshina Afsha , Hingorani Anil , Alsheekh Ahmad , Kibrik Pavel , Marks Natalie , Ascher Enrico
Published: March 2018

Objective:

It has been a widely accepted practice that a previous placed pacemaker, automatic implantable cardioverter defibrillators, or central line can be a contraindication to placing a hemodialysis catheter in the ipsilateral jugular vein. Fear of dislodging pacing wires, tunneling close to the battery site or causing venous obstruction has been a concern for surgeons and interventionalists alike. We suggest that this phobia may be unfounded.

Methods:

A retrospective review was conducted of patients in whom hemodialysis catheters were placed over a period of 10 years. For each hemodialysis catheter that was placed, perioperative chest X-ray performed was used to evaluate for pre-existing pacemakers and central lines. The position and laterality of placement of the hemodialysis catheter along with presence of arteriovenous fistula with functional capacity for access were noted.

Results:

A total of 600 hemodialysis catheters were placed in patients over the period of 10 years. The mean age of the patients was 73.6 ± 12 years with a median age of 76 years. We found 20 pacemakers or automatic implantable cardioverter defibrillators and 19 central lines on the same side of the neck as the hemodialysis catheter that was placed in the ipsilateral jugular vein. No patient exhibited malfunction or dislodgment of the central line, the pacemaker, or automatic implantable cardioverter defibrillator or evidence of upper extremity venous obstruction based upon signs symptoms or duplex exams.

Conclusion:

Based on our experience, we suggest that placement of hemodialysis catheter in the internal jugular vein ipsilateral to the pre-existing catheter/leads is safe and spares the contralateral limb for arteriovenous fistula creation.
Implanted ports in adults with primary immunodeficiency
Authors: Barton James C , Barton Jackson Clayborn , Bertoli Luigi F
Published: March 2018

Background:

We sought to learn more about the utility and safety of implanted ports for monthly immunoglobulin G infusions in adults with primary immune deficiency.

Methods:

We reviewed charts of adults who were referred to a single practice during the interval 2006–2016 for evaluation and management of frequent or severe upper and lower respiratory tract and other infections, subnormal total immunoglobulin G or immunoglobulin G subclasses, and suboptimal responses to polyvalent pneumococcal polysaccharide vaccinations; were diagnosed to have primary immune deficiency; and were advised to undergo immunoglobulin G therapy.

Results:

Of 606 patients, 20 (19 women, 1 man; 16 immunoglobulin G subclass deficiency, 4 common variable immunodeficiency; 3.3%) needed implanted ports because they had inadequate upper extremity superficial venous access. Median age at diagnosis was 48 years (range: 32–65 years). In total, 17 of the 20 patients preferred monthly in-office intravenous immunoglobulin G treatment to weekly at-home subcutaneous immunoglobulin G. The other three patients could not be treated with subcutaneous immunoglobulin G (unfavorable self-treatment experiences and insurance limitations). Median duration of treatment via implanted ports was 73 months (range: 10–153 months). In the man, the first implanted port was replaced after 26 months due to catheter fracture of unknown cause. His second port has been used for 112 months. We observed no other port-related failure, infections, thrombosis, or other adverse events.

Conclusion:

The utility and safety of implanted ports in adults with primary immune deficiency for whom subcutaneous immunoglobulin G therapy is not desired or feasible are probably similar to those of ports in patients without primary immune deficiency.
Mothers of Corn: Wixárika women, verbal performances, and ontology
Authors: García-Weyandt Cyndy Margarita
Published: March 2018

Wixáritari (pl.) from Western Mexico perform a series of ceremonies through the cultivation and harvesting of Corn. In communities outside Wixárika land, families align their ceremonies to the academic calendar and working calendar to ensure the families’ participation. This article discusses the active role of Maize within ceremony from cultivation to harvesting, emphasizing the role of women in preparing Corn-based substances for ceremonial offerings. Through storytelling and embodied practices such as gastronomic representations, women are active agents in transmitting the relationships between Corn and community members. Drawing from my ongoing ethnographic fieldwork among Wixárika families in Tepic, Mexico, the article analyzes the ontological relationship between Wixárika and Corn. Utilizing verbal performances such as storytelling, this article highlights the importance of Maize for purposes of continuing the community’s connection to geographies, identity and the significance of women in enabling inter-species relations.

Published: March 2018

Background:

Restriction spectrum imaging (RSI) is a recently introduced magnetic resonance imaging diffusion technique. The utility of RSI in multiple sclerosis (MS) is unknown.

Objective:

To investigate the association between RSI-derived parameters and neurological disability in MS.

Methods:

Seventy-seven relapsing–remitting MS patients were scanned with RSI on a 3-T scanner. RSI-derived parameters: fast and slow apparent diffusion coefficient (sADC), fractional anisotropy, restricted fractional anisotropy, neurite density (ND), cellularity, extracellular water fraction, and free water fraction, were obtained in white matter lesions (WML) and normal appearing white matter (NAWM). Patients were divided into three groups according to their expanded disability status scale (EDSS): with minimal, low, and substantial disability (<2.5, 2.5–3, and >3, respectively). Group comparisons and correlation analyses were performed.

Results:

All tested RSI-derived parameters differed between WML and NAWM ( p < 0.001 for all pairwise comparisons). The sADC in WML showed largest difference across disability subgroups (analysis of variance (ANOVA): F = 5.1, η2 = 0.12, p = 0.008). ND in NAWM showed strongest correlation with disability (ϱ = –0.39, p < 0.001).

Conclusion:

The strongest correlation with EDSS of ND obtained in NAWM indicates that processes outside lesions are important for disability in MS. Our study suggests that RSI-derived parameters may help understand the “clinico-radiological paradox” and improve disease monitoring in MS.
Beliefs of Slovenian early childhood educators regarding the implementation of physical education
Authors: Marinsek Miha , Kovac Marjeta
Published: March 2018

This cross-sectional study was designed to identify Slovenian early childhood educators’ beliefs concerning the importance of the competencies required to carry out physical education (PE), to identify which of those competencies early childhood educators might lack and to identify which competencies should be developed in the process of continuous professional development. For this purpose, a self-administered questionnaire was designed to examine belief statements regarding a wide scope of PE competencies among 183 early childhood educators. The participants evaluated the importance of individual competencies and reported their current and desired levels of competencies using a four-level scale. The results showed that early childhood educators believe that competencies to teach PE are an important part of early childhood education and that they need to improve in such competencies to carry out PE above the existing level. In particular, early childhood educators would like to improve in knowledge, skills and abilities that will enable them to implement PE efficiently and effectively to change children’s health-related behaviours. We suggest that the gap between the self-reported beliefs about the current level of PE competencies and the desired level of PE competencies is vital for policy-makers, who aim to create unitary early childhood education and care systems in which similar qualifications and competencies among early childhood educators are needed. It seems that a lack of policy, curriculum development and educators’ expertise in PE contributes to the considerable variation in the understanding of the educational role of early childhood educators within PE.
The extraordinary case of Russian performance artist Pyotr Pavlensky: Psychopathology or contemporary art?
Authors: Mendelevich Vladimir D.
Published: March 2018

This article examines the psychiatric and political issues surrounding the case of the controversial Russian performance artist Pyotr Pavlensky, who received a number of court-ordered psychiatric evaluations as part of the legal actions initiated subsequent to his political protest actions. The author presents the results of his own clinical investigation into Pavlensky’s case, arguing that previous diagnoses made by psychiatrists were unwarranted and unreasonable. This case draws the attention of experts to a problem: the need for more accurate criteria for the differentiation of behavioral disorders from behavior understood locally as socially-deviant. This issue is especially relevant during the assessment of the mental health of persons engaged in socially transgressive behavior which is explicitly framed as aesthetic and political action.
Fatigue life evaluation of continuous welded rails on concrete slab track in Korea high-speed railway
Authors: Sung Deok-Yong , Han Sung-Cheon
Published: March 2018

There is a rapidly increasing demand for continuous welded rails. Continuous welded rails provide a more suitable installation on concrete slab tracks and more rapid and smooth movement and reduce overall maintenance cost. During the relatively short period in which concrete slab tracks have been used in Korea, there has been no documented case of rail fracture caused by repeated loading. This makes the evaluation of rail fatigue life using field data more difficult. In this study, the rail bending stress developed during high-speed train operation is obtained through analysis of vehicle–track interaction, and the correlation is analyzed by performing multiple regression analysis on train speed and rail surface irregularities. Equations for predicting the rail bending stress with regard to train speed and rail surface irregularity were derived. The effects of vehicle speed, track support stiffness, and fracture probability on the fatigue life of continuous welded rails on a concrete slab track in Korea high-speed railway were analyzed.

Objective

To assess the differences in the types of injuries sustained by surfboard and bodyboard riders and to identify common mechanisms of injury.

Methods

Subjects were prospectively recruited to the study on presentation to one of the six hospital emergency departments. Consented subjects completed a questionnaire while in the emergency departments. Data regarding radiological investigations undertaken and their findings were collected retrospectively.

Results

A total of 224 males and 28 females in the surfing group and 14 males in the bodyboard group were recruited. In surfers, the most common injured body parts were the head/face (115; 45.6%) and lower limb (69; 27.4%). Surfers were most commonly injured by a surfboard, either their own (178; 70.6%) or someone else’s (18; 7.1%). Unfortunately, the small number of subjects recruited to the bodyboard group precluded meaningful comparison with the surfing group.

Conclusions

The most common body part injured in surfers is the head/face compared with the lower limbs in bodyboard riders. Contact with a surfer’s board (most commonly their own) is the most common cause of injury. Significant spinal fractures/injuries are sustained when the surfer (usually their head) strikes the seafloor. Head and facial fractures occur when the surfer is struck by their own board. Future research into surfboard design which incorporates softer compounds into the deck, rail, and fins is recommended. The need for local authorities and surf lifesavers to disseminate information relating to specific beaches to the general public regarding surf conditions, water depth, and the nature of the seafloor is also essential for injury prevention.

External flow velocity and synthetic jets parameters influence on cavity flow structure and acoustics characteristics using RANS/ILES
Authors: Lyubimov Dmitriy , Fedorenko Alena
Published: March 2018

An influence of synthetic jets on the flow in a three-dimensional cavity M219 was studied using RANS/ILES method. Calculations were performed for Mach numbers M0  =  0.85 and M0 = 1.5. Synthetic jets’ operating parameters such as their position, number, frequency, and amplitude were varied. An impact of these parameters and M0 on flow in the cavity, distributions, and levels of pressure fluctuations on the cavity walls as well as the narrowband spectra of pressure fluctuations were obtained. Synthetic jets located in front of a cavity may reduce peak pressure pulsations on the cavity back wall by 37% for a subsonic external flow. Moreover, it was found that synthetic jets may decrease the second and the third modes of pressure fluctuations on the back wall both for subsonic flow and supersonic case.
Cross-Age Peer E-Mentoring to Support Social Media Use: A New Focus for Intervention Research
Authors: Grace Emma , Raghavendra Parimala
Published: March 2018

Young people who use augmentative and alternative communication (AAC) can experience reduced social participation and continue to face challenges in developing and using communication and literacy skills for real-life contexts. Drawing on emerging research, this discussion article highlights the potential benefits and advantages of participation in online conversations with peers as an additional support to both communication development and social participation for this group. Cross-Age peer e-mentoring to support participation in social media is proposed as a potential intervention strategy to enhance social participation and at the same time improve communicative competence and literacy for young people who use AAC.
Client Perceptions of Task-Oriented Training at Home: “I Forgot I Was Sick”
Authors: Rowe Veronica T. , Neville Marsha
Published: March 2018

Task-oriented training is a contemporary intervention based on behavioral neuroscience and recent models of motor learning. It can logically be guided by the theory of occupational adaptation. This report presents the perceptions of four participants who underwent task-oriented training at home (TOTE Home) for upper extremity hemiparesis following a stroke. Guided by principles of motor learning and the theory of occupational adaptation, a directed content analysis was used with field notes recorded during the TOTE Home. Three themes emerged: salience of the activity within context, desire for mastery by creating the just right challenge, and adapted self-perception of abilities. While motor learning principles informed the method of task practice and feedback, it was the person’s desire to perform meaningful, relevant activities that drove the adaptive process. This study provided insight in the perceptions and experiences of participants undergoing TOTE Home.
The Effect of Pelvic Floor Muscle Training On Incontinence Problems After Radical Prostatectomy
Authors: Aydın Sayılan Aylin , Özbaş Ayfer
Published: March 2018

The aim of the current study was to determine the effect of pelvic floor muscle exercises (PFME/Kegel) training administered to patients scheduled for robot-assisted radical prostatectomy on postprocedural incontinence problems.

This study was a randomized controlled trial. Pelvic floor muscle exercises were applied to the procedure group three times a day for 6 months. No exercises were applied to the control group. Incontinence and quality-of-life assessments of the 60 patients in the experimental and control groups were performed on months 0 (10 days after removal of the urinary catheter), 1, 3, and 6 through face-to-face and telephone interviews.

Total Incontinence Consultation on Incontinence-Short Form scores, which provide an objective criterion for the evaluation of individuals with incontinence problems, decreased over time. This decrease was statistically highly significant in the third and sixth months.

Pelvic muscle floor exercises are suitable for patients experiencing incontinence after radical prostatectomy.
“I should have …”:A Photovoice Study With Women Who Have Lost a Man to Suicide
Authors: Creighton Genevieve , Oliffe John L. , Bottorff Joan , Johnson Joy
Published: March 2018

While the gendered nature of suicide has received increased research attention, the experiences of women who have lost a man to suicide are poorly understood. Drawing on qualitative photovoice interviews with 29 women who lost a man to suicide, we completed a narrative analysis, focused on describing the ways that women constructed and accounted for their experiences. We found that women’s narratives drew upon feminine ideals of caring for men’s health, which in turn gave rise to feelings of guilt over the man’s suicide. The women resisted holding men responsible for the suicide and tended to blame themselves, especially when they perceived their efforts to support the man as inadequate. Even when women acknowledged their guilt as illogical, they were seemingly unable to entirely escape regret and self-blame. In order to reformulate and avoid reifying feminine ideals synonymous with selflessly caring for others regardless of the costs to their own well-being, women’s postsuicide bereavement support programs should integrate a critical gender approach.
