Mastery and Belonging or Inspiration Porn and Bullying: Special Populations in Youth Sport
Authors: Martin Jeffrey J. 
Published: September 2019

This paper examines the factors that make up a high-quality youth-sport experience for special-population children. It is important to note that special-population youth are often very similar to nondisabled children (e.g., seeking enjoyment in sport), but they experience different contexts and socialization experiences such as fewer opportunities and more barriers to sport participation. The author first examines positive factors in the youth-sport experience and discusses mastery experiences and the generation of positive affect. He also discusses how sport can promote feelings of belongingness, freedom, and independence. In the second part of the paper he discusses how the youth-sport experience can contribute to a negative experience by examining bullying and teasing, as well as “inspiration porn.” Inspiration porn is a relatively new concept in the disability literature that has not been discussed in a sport context. The author proposes a five-component model that links anecdotal reports of inspiration porn to theory, thus providing a basis for future research on inspiration porn. Throughout the paper he examines research in each area, theories used, important findings, salient take-home points, and future research directions and imbues the paper in a disability social-relational model that asserts that individual, social, environmental, and cultural factors all play a role as proximal and distal influences in the sport experiences of special-population youth.
Three-dimensional crystals of adaptive knots
Authors: Tai Jung-Shen B. , Smalyukh Ivan I. 
Published: September 2019

Knot all that it seems
Although for some, knots are merely a frustration caused by poorly tied shoelaces, interest in knots in physical systems spans many disciplines, including fluid and optical vortices, Skyrmion states, liquid crystals, excitable media, polymers, proteins, DNA, and even chemical molecules. Tai and Smalyukh describe the creation of localized knotted structures in cholesteric liquid crystals using electric fields (see the Perspective by Alexander). The knots are topologically distinct from the host medium and diffuse and organize like colloidal particles, forming regular crystalline arrangements.

Published: September 2019

Abstract

Objective
To compare the risk and severity of prostate cancer between men achieving fatherhood by assisted reproduction and men conceiving naturally.

Design
National register based cohort study.

Setting
Sweden from January 1994 to December 2014.

Participants
1 181 490 children born alive in Sweden during 1994-2014 to the same number of fathers. Fathers were grouped according to fertility status by mode of conception: 20 618 by in vitro fertilisation (IVF), 14 882 by intra-cytoplasmic sperm injection (ICSI), and 1 145 990 by natural conception.

Main outcome measures
Prostate cancer diagnosis, age of onset, and androgen deprivation therapy (serving as proxy for advanced or metastatic malignancy).

Results
Among men achieving fatherhood by IVF, by ICSI, and by non-assisted means, 77 (0.37%), 63 (0.42%), and 3244 (0.28%), respectively, were diagnosed as having prostate cancer. Mean age at onset was 55.9, 55.1, and 57.1 years, respectively. Men who became fathers through assisted reproduction had a statistically significantly increased risk of prostate cancer compared with men who conceived naturally (hazard ratio 1.64, 95% confidence interval 1.25 to 2.15, for ICSI; 1.33, 1.06 to 1.66, for IVF). They also had an increased risk of early onset disease (that is, diagnosis before age 55 years) (hazard ratio 1.86, 1.25 to 2.77, for ICSI; 1.51, 1.09 to 2.08, for IVF). Fathers who conceived through ICSI and developed prostate cancer received androgen deprivation therapy to at least the same extent as the reference group (odds ratio 1.91; P=0.07).

Conclusions
Men who achieved fatherhood through assisted reproduction techniques, particularly through ICSI, are at increased risk for early onset prostate cancer and thus constitute a risk group in which testing and careful long term follow-up for prostate cancer may be beneficial.
Job satisfaction, work commitment and intention to leave among pharmacists: a cross-sectional study
Authors: Al-Muallem Nedaa , Al-Surimi Khaled Mohammed 
Published: September 2019

ObjectivesWe assessed job satisfaction, work commitment and intention to leave among pharmacists working in different healthcare settings in Saudi Arabia.DesignThis was a cross-sectional study utilising a previously validated questionnaire.SettingWe surveyed the workforce at different healthcare settings in Riyadh, Saudi Arabia.ParticipantsThe participants were pharmacists licensed by the Saudi Commission for Health Specialties.Outcome measuresWe examined job satisfaction, work commitment and intention to leave.ResultsIn total, 325 out of 515 pharmacists completed the questionnaire, yielding a response rate of 63%. Over half of them were women (57.8%), 78.2% were Saudi Arabian nationals and 61.8% were married. The majority (88.1%) worked between 36 and 44 hours per week; 96.6% were full-time employees, and 63.4% were government employees working in public hospitals or primary healthcare centres. Although most of the pharmacists were satisfied (satisfied and slightly satisfied) with their current job (39.1% and 24.6%, respectively), about two-thirds (61.9%) had the intention to leave. Multiple logistic regression analysis showed that the most important predictors of pharmacists’ intentions to leave were related to job satisfaction and work commitment (OR=0.923; 95% CI 0.899 to 0.947; p<0.001 and OR=1.044; 95% CI 1.014 to 1.08; p=0.004, respectively), whereas respondents’ demographic characteristics had no effect.ConclusionsAlthough the pharmacists surveyed were satisfied and committed to their current job, they had the intention to leave. Further research is recommended to clarify why pharmacists in Saudi Arabia have the intention to leave their pharmacy practice job.
Migration status and prevalence of diabetes and hypertension in Gauteng province, South Africa: effect modification by demographic and socioeconomic characteristics—a cross-sectional population-based study
Authors: Motlhale Melitah , Ncayiyana Jabulani Ronnie 
Published: September 2019

IntroductionEvidence from low-income and middle-income countries suggests that migration status has an impact on health. However, little is known about the effect that migration status has on morbidity in sub-Saharan Africa. The aim of this study is to investigate the association between migration status and hypertension and diabetes and to assess whether the association was modified by demographic and socioeconomic characteristics.MethodsA Quality ofLife survey conducted in 2015 collected data on migration status and morbidity from a sample of 28 007 adults in 508 administrative wards in Gauteng province (GP). Migration status was divided into three groups: non-migrant if born in Gauteng province, internal migrant if born in other South African provinces, and external migrant if born outside of South Africa. Diabetes and hypertension were defined based on self-reported clinical diagnosis. We applied a recently developed original, stepwise-multilevel logistic regression of discriminatory accuracy to investigate the association between migration status and hypertension and diabetes. Potential effect modification by age, sex, race, socioeconomic status (SES) and ward-level deprivation on the association between migration status and morbidities was tested.ResultsMigrants have lower prevalence of diabetes and hypertension. In multilevel models, migrants had lower odds of reporting hypertension than internal migrants (OR=0.86; 95% CI 0.78 to 0.95) and external migrant (OR=0.60; 95% CI 0.49 to 0.75). Being a migrant was also associated with lower diabetes prevalence than being an internal migrant (OR=0.84; 95% CI 0.75 to 0.94) and external migrant (OR=0.53; 95% CI 0.41 to 0.68). Age, race and SES were significant effect modifiers of the association between migration status and morbidities. There was also substantial residual between-ward variance in hypertension and diabetes with median OR of 1.61 and 1.24, respectively.ConclusionsMigration status is associated with prevalence of two non-communicable conditions. The association was modified by age, race and SES. Ward-level effects also explain differences in association.

ObjectiveOverweight and obesity have been shown to be related to multiple chronic conditions, leading to a heavy economic burden on society throughout the world. This study aims to estimate the prevalence of overweight and obesity and determine potential influencing factors among adults in Xinjiang, northwest China.DesignA community-based observational study.SettingThe First Affiliated Hospital of Xinjiang Medical University.MethodsIn total, 14 618 adult participants (7799 males; 6819 females) aged over 35 years were recruited from the Cardiovascular Risk Survey conducted in 2010. Data were obtained from face-to-face interviews and physical examinations. The sample was used to estimate the prevalence of overweight (body mass index (BMI) 24–28 kg/m2) and obesity (BMI ≥28 kg/m2) in Xinjiang Province. Influencing factors were analysed based on statistical methods.ResultsIn Xinjiang Province, the overall prevalence of overweight was 36.5% (male 40.1%; female 33.4%), and the prevalence of obesity was 26.5% (male 27.2%; female 25.8%). The prevalence of both overweight and obesity were higher in women than in men (p<0.001). The main influencing factors for overweight and obesity were sex, age, race, marital status, education level, occupation, smoking, drinking, hypertension, diabetes and dyslipidaemia (p<0.05).ConclusionsThis study estimated that the prevalence of overweight and obesity among adult residents of Xinjiang Province, northwest China, was high. These data suggest that efforts related to the prevention and control of overweight and obesity should be a public health priority in northwest China.

Published: September 2019

ObjectivesDespite the negative influence of fatigue on quality of life in patients who undergo lung cancer surgery, little is known about the possible predictors of postoperative fatigue. The aim of this study was to examine demographic and clinical characteristics that might predict postoperative fatigue 5 months after lung cancer surgery.DesignA prospective longitudinal follow-up study comprising preoperative and postoperative questionnaires, including Lee Fatigue Scale, and sociodemographic and clinical data.SettingThree university hospitals in Norway (eg, Oslo University Hospital, St. Olav University Hospital and Haukeland University Hospital).ParticipantsIn total, 196 surgically treated patients who answered the questionnaires both preoperatively and at 5-month follow-up with valid fatigue scores.ResultsBivariate analyses showed that preoperative fatigue was associated with comorbidities and the symptoms of shortness of breath, cough, depression, anxiety, sleep disturbance and pain. Only cough was directly associated with preoperative fatigue in a regression model. Comorbidities and the symptoms of shortness of breath, cough, depression and sleep disturbance were associated with postoperative fatigue in the bivariate analyses, but only shortness of breath was associated with postoperative fatigue in the regression model. We did not find any significant correlations between fatigue and any treatment variable.ConclusionClinicians should pay special attention to lung symptoms and be aware that these may lead to long-term postoperative fatigue. Further research should examine whether interventions reducing lung symptoms, such as shortness of breath and coughing, may prevent development of fatigue in patients undergoing lung cancer surgery.
What are the important design features of personal health records to improve medication adherence for patients with long-term conditions? A systematic literature review
Authors: Andrikopoulou Elisavet , Scott Philip , Herrera Helena , Good Alice 
Published: September 2019

ObjectivesThis systematic literature review aims to identify important design features of the electronic personal health record (PHR) that may improve medication adherence in the adult population with long-term conditions.Data sourcesPubMed (including MEDLINE), CINAHL, Science Direct (including EMBASE), BioMed Central, ACM digital, Emerald Insight, Google Scholar and Research Gate.MethodsStudies that were published between 1 January 2002 and 31 May 2018 in English were included if the participants were adults, with at least one long-term condition, were able to self-administer their medication and were treated in primary care settings. The quality of evidence was assessed with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system and the risk of bias was appraised using the Cochrane risk of bias tool.ResultsFrom a total of 27 studies that matched the inclusion criteria, 12 were excluded due to low quality of evidence, 10 were rated moderate and 5 were rated high quality. All the included studies had low sample size and limited follow-up duration. Thirteen of the included studies found that the use of a PHR has increased medication adherence. The identified design features are reminders, education, personalisation and tailoring, feedback and alerts, gamification, medication management, medical appointment management, diary and self-monitoring, health condition management, set goals, patient’s blog and tethered. It was impossible to draw conclusions as to which feature is important to what group of patients and why. The most frequently identified conditions were HIV and diabetes. This review did not identify any papers with negative results. It was not possible to numerically aggregate the PHR effect due to high heterogeneity of the medication adherence measurement, study type, participants and PHRs used.ConclusionAlthough we found recurrent evidence that PHRs can improve medication adherence, there is little evidence to date to indicate which design features facilitate this process.PROSPERO registration numberCRD42017060542.

Published: September 2019

ObjectivesStudies have shown that organisational injustice (OIJ) is associated with mental disorders. However, there is little research regarding details on OIJ exposure. We examined the effect of OIJ on serious psychological distress (SPD) by considering the exposure frequency, the exposure duration and the OIJ-free period after the disappearance of exposure.MethodsWe used a prospective cohort design. OIJ exposure was assessed three times with 1-year intervals between assessments, and the subjects were grouped according to the exposure histories. The outcome assessment for SPD by scores of 13 or higher on the K6 questionnaire was carried out 3 years after the baseline scores were obtained. Participants were all full-time regular employees of one office of a manufacturing company in Japan. Participants who were being treated for mental disorders, those with SPD and those with missing data on the K6 questionnaire in the baseline survey were excluded from the prospective cohort. Self-reported questionnaire data from 1087 employees who participated in all surveys and answered all questions were analysed. Logistic regression analysis was used to explore the effect of OIJ on SPD.ResultsSPD developed in 35 participants. Frequent OIJ exposure was associated with a higher risk for SPD (p for trend=0.002). Of the 1087 participants, 319 (29.3%) experienced a change in OIJ exposure at least once, and 8.6% of subjects experienced such a change twice. These changes in OIJ exposure were more strongly related to SPD than was the frequency of OIJ exposure.ConclusionsOIJ was associated with SPD onset particularly when the workers were more frequently exposed to it. Moreover, frequent changes in the OIJ exposure were associated with a higher risk for SPD. Because OIJ exposure can change in a relatively short time, considering exposure histories may provide useful information for preventing mental disorders.

IntroductionChildren with the single-gene disorder neurofibromatosis type 1 (NF1) appear to be at an increased risk for autism spectrum disorder (ASD) and exhibit a unique social-cognitive phenotype compared with children with idiopathic ASD. A complete framework is required to better understand autism in NF1, from neurobiological levels through to behavioural and functional outcomes. The primary aims of this study are to establish the frequency of ASD in children with NF1, examine the social cognitive phenotype, investigate the neuropsychological processes contributing to ASD symptoms and poor social functioning in children with NF1, and to investigate novel structural and functional neurobiological markers of ASD and social dysfunction in NF1. The secondary aim of this study is to compare the neuropsychological and neurobiological features of ASD in children with NF1 to a matched group of patients with idiopathic ASD.Methods and analysisThis is an international, multisite, prospective, cross-sectional cohort study of children with NF1, idiopathic ASD and typically developing (TD) controls. Participants will be 200 children with NF1 (3–15 years of age), 70 TD participants (3–15 years) and 35 children with idiopathic ASD (7–15 years). Idiopathic ASD and NF1 cases will be matched on age, sex and intelligence. All participants will complete cognitive testing and parents will rate their child’s behaviour on standardised questionnaires. Neuroimaging will be completed by a subset of participants aged 7 years and older. Children with NF1 that screen at risk for ASD on the parent-rated Social Responsiveness Scale 2nd Edition will be invited back to complete the Autism Diagnostic Observation Scale 2nd Edition and Autism Diagnostic Interview-Revised to determine whether they fulfil ASD diagnostic criteria.Ethics and disseminationThis study has hospital ethics approval and the results will be disseminated through peer-reviewed publications and international conferences.

ObjectivesPAX-Good Behaviour Game (PAX-GBG) is associated with improved mental health among youth. First Nations community members decided on a whole school approach to facilitate PAX-GBG implementation, by offering intervention training to all staff members in their schools. Our objective is to gain a greater understanding of how this approach was viewed by school personnel, in order to improve implementation in remote and northern First Nations communities.DesignWe conducted a qualitative case study using semi-structured interviews.SettingInterviews were conducted in First Nations schools located in northern Manitoba, Canada, in February 2018.ParticipantsWe used purposive sampling in selecting the 23 school staff from First Nations communities.InterventionPAX-GBG is a mental health promotion intervention that teachers deliver in the classroom alongside normal instructional activities. It was implemented school-wide over 4 months from October 2017 to February 2018.Outcome measuresWe inquired about the participants’ perception of PAX-GBG and the whole school approach. We applied an iterative coding system, identified recurring ideas and classified the ideas into major categories.ResultsImplementing the PAX-GBG whole school approach improved students’ behaviour and created a positive school environment. Students were learning self-regulation, had quieter voices and demonstrated awareness of the PAX-GBG strategies. All teachers interviewed had used the programme. Support from school administrators and having all school personnel use the programme consistently were facilitators to successful implementation. Challenges included the timing of training, lack of clarity in how to implement and implementing among students in older grades and those with special needs.ConclusionsThe whole school approach to implementing PAX-GBG was viewed as an acceptable and feasible way to extend the reach of PAX-GBG in order to promote the mental health of First Nations youth. Recommendations included ensuring school leadership support, changes to the training and cultural and literacy adaptations.
