Isokinetic strength assessment offers limited predictive validity for detecting risk of future hamstring strain in sport: a systematic review and meta-analysis
Authors: Green Brady , Bourne Matthew N , Pizzari Tania 
Published: November 2017

ObjectiveTo examine the value of isokinetic strength assessment for predicting risk of hamstring strain injury, and to direct future research into hamstring strain injuries.DesignSystematic review.Data sourcesDatabase searches for Medline, CINAHL, Embase, AMED, AUSPORT, SPORTDiscus, PEDro and Cochrane Library from inception to April 2017. Manual reference checks, ahead-of-press and citation tracking.Eligibility criteria for selecting studiesProspective studies evaluating isokinetic hamstrings, quadriceps and hip extensor strength testing as a risk factor for occurrence of hamstring muscle strain.MethodsIndependent search result screening. Risk of bias assessment by independent reviewers using Quality in Prognosis Studies tool. Best evidence synthesis and meta-analyses of standardised mean difference (SMD).ResultsTwelve studies were included, capturing 508 hamstring strain injuries in 2912 athletes. Isokinetic knee flexor, knee extensor and hip extensor outputs were examined at angular velocities ranging 30–300°/s, concentric or eccentric, and relative (Nm/kg) or absolute (Nm) measures. Strength ratios ranged between 30°/s and 300°/s. Meta-analyses revealed a small, significant predictive effect for absolute (SMD=−0.16, P=0.04, 95% CI −0.31 to −0.01) and relative (SMD=−0.17, P=0.03, 95% CI −0.33 to −0.014) eccentric knee flexor strength (60°/s). No other testing speed or strength ratio showed statistical association. Best evidence synthesis found over half of all variables had moderate or strong evidence for no association with future hamstring injury.Summary/ConclusionDespite an isolated finding for eccentric knee flexor strength at slow speeds, the role and application of isokinetic assessment for predicting hamstring strain risk should be reconsidered, particularly given costs and specialised training required.

ObjectivesOver two million people in the UK are living with and beyond cancer. A third report diminished quality of life.DesignA review of published systematic reviews to identify effective non-pharmacological interventions to improve the quality of life of cancer survivors.Data sourcesDatabases searched until May 2017 included PubMed, Cochrane Central, EMBASE, MEDLINE, Web of Science, the Cumulative Index to Nursing and Allied Health Literature, and PsycINFO.Study selectionPublished systematic reviews of randomised trials of non-pharmacological interventions for people living with and beyond cancer were included; included reviews targeted patients aged over 18. All participants had already received a cancer diagnosis. Interventions located in any healthcare setting, home or online were included. Reviews of alternative therapies or those non-English reports were excluded. Two researchers independently assessed titles, abstracts and the full text of papers, and independently extracted the data.OutcomesThe primary outcome of interest was any measure of global (overall) quality of life.Analytical methodsQuality assessment assessing methdological quality of systematic reviews (AMSTAR) and narrative synthesis, evaluating effectiveness of non-pharmacological interventions and their components.ResultsOf 14 430 unique titles, 21 were included in the review of reviews. There was little overlap in the primary papers across these reviews. Thirteen reviews covered mixed tumour groups, seven focused on breast cancer and one focused on prostate cancer. Face-to-face interventions were often combined with online, telephone and paper-based reading materials. Interventions included physical, psychological or behavioural, multidimensional rehabilitation and online approaches. Yoga specifically, physical exercise more generally, cognitive behavioural therapy (CBT) and mindfulness-based stress reduction (MBSR) programmes showed benefit in terms of quality of life.ConclusionsExercise-based interventions were effective in the short (less than 3–8 months) and long term. CBT and MBSR also showed benefits, especially in the short term. The evidence for multidisciplinary, online and educational interventions was equivocal.

Published: November 2017

ObjectiveThe present study aimed to evaluate the association between smoking and incident pterygium in adult Korean men.DesignA retrospective nationwide longitudinal cohort.SettingNational Health Insurance database of South Korea.ParticipantsThis study included Korean men (age range: 40–79 years) registered in the Korea National Health Insurance Service database from 2002 through 2013. We compared HRs for pterygium between 90 547 current/past and 90 547 never-smokers via 1:1 propensity-matched analysis.Primary outcome measureIncident cases of pterygium were identified from the database.ResultsPterygium developed in 5389 (6.0%) never-smokers and 3898 (4.3%) past/current smokers (P<0.001). The incidence of pterygium per 1000 person-years in never-smokers and in past/current smokers was 6.5 and 4.7, respectively (age-adjusted HR, 0.73; 95% CI, 0.70 to 0.76). This protective effect was more pronounced among current smokers than among past smokers (for current smokers: HR, 0.68; 95% CI, 0.65 to 0.71 and for past smokers: HR, 0.85; 95% CI, 0.80 to 0.90). A longer duration of smoking and higher amounts of cigarette consumption were associated with a lower incidence of pterygium.ConclusionsLongitudinally, cigarette smoking was associated with a reduced risk of pterygium, and this protective effect was more pronounced among current smokers than among past smokers.

Published: November 2017

ObjectivesHypertensive disorders of pregnancy (HDP) affect one in ten pregnancies and often persist postpartum when complications can occur. We aimed to determine the effectiveness and safety of pharmacological interventions, other interventions and different care models for postpartum hypertension management.DesignA systematic review was undertaken. Nine electronic databases, including Medline, were searched from inception to 16 March 2017. After duplicate removal, 4561 records were screened. Two authors independently selected studies, extracted study characteristics and data, and assessed methodological quality.SettingRandomised controlled trials, case–control studies and cohort studies from any country and healthcare setting.ParticipantsPostnatal women with HDP.InterventionsTherapeutic intervention for management of hypertension, compared with another intervention, placebo or no intervention.Primary and secondary outcome measuresOutcome data were collected for maternal mortality and severe morbidity; systolic, diastolic and mean arterial blood pressure (BP) control; and safety data. Secondary outcome data collected included the length of postnatal hospital stay and laboratory values.Results39 studies were included (n=2901). Results were heterogeneous in terms of intervention, comparison and outcome requiring a narrative approach. There were insufficient data to recommend any single pharmacological intervention. 18 studies reported calcium-channel blockers, vasodilators and beta-blockers lowered BP postpartum. 12 of these reported safety data. Limited data existed regarding management in the weeks following hospital discharge. Neither loop diuretics (three studies) nor corticosteroids (one study) produced clinical benefit. Uterine curettage significantly reduced BP over the first 48 hours postpartum (range 6–13 mm Hg) compared with standard care (eight studies), with safety data only reported by four of eight studies.ConclusionThere was insufficient evidence to recommend a particular BP threshold, agent or model of care, but three classes of antihypertensive appeared variably effective. Further comparative research, including robust safety data, is required. Curettage reduced BP, but without adequate reporting of harms, so it cannot currently be recommended.

Published: November 2017

ObjectiveThe pathogenesis of venous outflow stenosis associated with cerebral arteriovenous malformation (AVM) draining veins is poorly understood. We sought to determine the relationship between venous stenosis and atherosclerotic risk factors.Materials and methodsAll patients with an AVM seen at our institution between 1990 and 2016 were retrospectively reviewed. Patients <18 years of age were excluded. Patients were classified into two groups based on the presence or absence of venous stenosis. Patient charts were reviewed for the following atherosclerotic risk factors: age >50 years, sex, race, hypertension, type 2 diabetes mellitus, hyperlipidemia, coronary artery disease, chronic kidney disease stage III, and cigarette smoking. The relationship between venous stenosis and atherosclerotic risk factors was assessed using univariate and multivariate analyses.Results278 patients were included (mean age 41 years, 55% men). Venous stenosis was present in 87 patients (31% of the cohort). The presence of venous stenosis was significantly associated with age >50 years (P=0.05), hypertension (P=0.05), diabetes (P=0.02), and hyperlipidemia (P=0.001). Multivariate analysis showed that hyperlipidemia (P=0.05) was predictive of draining vein stenosis.ConclusionsVenous stenosis is associated with several atherosclerotic risk factors, suggesting that cerebral AVM venous outflow stenosis occurs by a degenerative process. Additional studies can show whether these modifiable risk factors may be targeted to prevent draining vein stenosis and AVM rupture.

Published: November 2017

BackgroundUrate is a strong antioxidant in plasma and may protect against lung function impairment. We tested the hypothesis that high plasma urate is causally associated with better lung function and low risk of respiratory symptoms and COPD.MethodsWe measured lung function and plasma urate in 114 979 individuals from the Copenhagen City Heart Study and the Copenhagen General Population Study and genotyped forSLC2A9rs7442295 andABCG2rs2231142 variants, previously associated with high plasma urate, in 110 152 individuals.ResultsIn the two studies combined, multivariable-adjusted 100 µmol/L higher plasma urate was associated with −1.54% (95% CI −1.67 to −1.40) lower FEV1% predicted and −1.57% (95% CI −1.69 to −1.44) lower FVC % predicted observationally; the corresponding estimates for genetically determined 100 µmol/L higher plasma urate were −0.46% (95% CI −1.17 to 0.25) and −0.40% (95% CI −1.03 to 0.23). High plasma urate was also associated with higher risk of respiratory symptoms; however, genetically determined high plasma urate was not associated with respiratory symptoms. Finally, we identified 14 151 individuals with COPD and found ORs of 1.08 (95% CI 1.06 to 1.11) for COPD observationally and 1.01 (95% CI 0.88 to 1.15) genetically per 100 µmol/L higher plasma urate.ConclusionHigh plasma urate was associated with worse lung function and higher risk of respiratory symptoms and COPD in observational analyses; however, genetically high plasma urate was not associated with any of these outcomes. Thus, our data do not support a direct causal relationship.
Effect of sensory attenuation on cortical movement-related oscillations
Authors: Lee Joseph J. , Schmit Brian D. 
Published: November 2017

This study examined the impact of induced sensory deficits on cortical, movement-related oscillations measured using electroencephalography (EEG). We hypothesized that EEG patterns in healthy subjects with induced sensory reduction would be comparable to EEG found after chronic loss of sensory feedback. EEG signals from 64 scalp locations were measured from 10 healthy subjects. Participants dorsiflexed their ankle after prolonged vibration of the tibialis anterior (TA). Beta band time frequency decompositions were calculated using wavelets and compared across conditions. Changes in patterns of movement-related brain activity were observed following attenuation of sensory feedback. A significant decrease in beta power of event-related synchronization was associated with simple ankle dorsiflexion after prolonged vibration of the TA. Attenuation of sensory feedback in young, healthy subjects led to a corresponding decrease in beta band synchronization. This temporary change in beta oscillations suggests that these modulations are a mechanism for sensorimotor integration. The loss of sensory feedback found in spinal cord injury patients contributes to changes in EEG signals underlying motor commands. Similar alterations in cortical signals in healthy subjects with reduced sensory feedback implies these changes reflect normal sensorimotor integration after reduced sensory input rather than brain plasticity. NEW & NOTEWORTHY Transient attenuation of sensory afferents in young, healthy adults led to similar changes in brain activity found previously in volunteers with incomplete spinal cord injury. Beta band power associated with ankle movement in these controls was attenuated after prolonged vibration of the tibialis anterior. Evoked potential measurements suggest that prolonged vibration reduces phasing across trials as the mechanism behind this attenuation of cortical activity.

Published: November 2017

The Sanjiangyuan region of Qinghai-Tibetan Plateau is recognized as a biodiversity hotspot of alpine mammals but a barren area in terms of amphibians and reptiles. Here, we describe a new pit viper species, Gloydius rubromaculatus sp. n. Shi, Li and Liu, 2017 that was discovered in this region, with a brief taxonomic revision of the genus Gloydius. The new species can be distinguished from the other congeneric species by the following characteristics: cardinal crossbands on the back, indistinct canthus rostralis, glossy dorsal scales, colubrid-like oval head shape, irregular small black spots on the head scales, black eyes and high altitude distribution (3300-4770 m above sea level). The mitochondrial phylogenetic reconstruction supported the validity of the new species and furthermore reaffirms that G. intermedius changdaoensis, G. halys cognatus, G. h. caraganus and G. h. stejnegeri should be elevated as full species. Gloydius rubromaculatus sp. n. was found to be insectivorous: preying on moths (Lepidoptera, Noctuidae, Sideridis sp.) in the wild. This unusual diet may be one of the key factors to the survival of this species in such a harsh alpine environment.
The Meaning of Honorary Whiteness for Asian Americans: Boundary Expansion or Something Else?
Authors: Shiao Jiannbin Lee 
Published: November 2017

AbstractResearch on interracial intimacy divides between quantitative comparisons of interracial and same-race marriages and qualitative studies of existing interracial unions. This article bridges the divide by examining how interracial dating histories differ from same-race dating histories among Asian Americans, a group that sociologists consistently regard as potentially having attained a racial status as “honorary whites.” Synthesizing the literatures on ethnic boundaries, homogamy, and interracial intimacy, the author examines the role of boundary processes in differentiating same-race and interracial dating histories. What does becoming honorary whites, as indicated by participation in racial exogamy, actually mean for Asian Americans? Using a unique sample of 83 Asian Americans with a wide range of dating histories, the author finds that social networks are a crucial mechanism for differentiating racial endogamy and exogamy. In addition, my results show that becoming honorary whites has critically involved boundary repositioning, rather than boundary transcendence, blurring, or expansion.
Moral Destabilisation or Revivification: The Trend of Religion-Based Social Capital Following 9/11
Authors: Yuksek Durmus A. 
Published: November 2017

AbstractAlthough different aspects of the 9/11 terrorist attacks have been widely studied, few researchers have attempted to understand both its religious and social aspects. In this context, considering the declining trend of social capital in the United States, whether 9/11 has become a window of opportunity for civic renewal and whether such renewal has been short-lived or long-lived become highly important to examine. To address these questions, this study examines whether the level of social capital in the American society changed from 2000 to 2006 and whether religious traditions had different effects on their members’ social capital levels following 9/11.
Can Maternal Spindle Transfer and Pronuclear Transfer Be Prohibited under eu Legislation?
Authors: MacKellar Calum 
Published: November 2017

Abstract
The question whether maternal spindle transfer (mst) and pronuclear transfer (pnt) can be prohibited under eu legislation was examined by the non-governmental organisation European Bioethics Research (ebr). It did so by submitting an official complaint to the eu Commission proposing that the uk Human Fertilisation and Embryology (Mitochondrial Donation) Regulations 2015 breached the prohibition on the modification of a person’s germ line genetic identity of the eu Clinical Trials Directive 2001/20/EC and the new Regulation eu 536/2014. A discussion then took place, during 2016, between ebr and the eu Commission whether mst and pnt principally involved a ‘medicinal product’ in which case the eu Clinical Trials Directive 2001/20/EC and Regulation eu 536/2014 would be applicable or whether the procedures just involved a medical procedure in which case the Tissue and Cells Directive 2004/23/EC was applicable which did not include any prohibition on the intentional modification of a person’s germline.
Psychological distress and unmet mental health needs among urban taxi drivers: A cross-sectional survey
Authors: Davidson Sandra , Wadley Greg , Reavley Nicola , Gunn Jane , Fletcher Susan 
Published: November 2017

Objectives: The taxi industry relies on a male-dominated, predominately immigrant workforce who face multiple risk factors for poor mental health including shift work, low pay and threats of violence. Despite these risk factors, no previous study has documented the prevalence of psychological distress in the taxi industry. We investigated psychological distress among urban taxi drivers and explored the factors associated with high levels of distress. Method: A total of 380 taxi drivers were surveyed at the Melbourne Airport holding yard between September 2016 and March 2017. Psychological distress was measured using the K10. Logistic regression models were used to estimate the association between high levels of psychological distress and migration, work patterns, potentially traumatic events, health care use and social connectedness. Results: A third (33%) of drivers had very high (K10 ⩾ 30) levels of distress and 28% had high (K10 = 22–29) levels of distress. Trauma was significantly associated with high levels of psychological distress, and rates of trauma were much higher among drivers than among the Australian population. Despite high levels of distress, drivers were no more likely than other Australian men to visit a health professional. Conclusion: Urban taxi drivers are at very high risk for mental health problems, yet the mental health needs of this largely immigrant workforce has gone largely unnoticed. Interventions tailored to the unique characteristics of the job and the demographic composition of the workforce are urgently needed.

Published: November 2017

Objective Three different team configurations are compared with the goal of better understanding human-autonomy teaming (HAT). Background Although an extensive literature on human-automation interaction exists, much less is known about HAT in which humans and autonomous agents interact as coordinated units. Further research must be conducted to better understand how all-human teams compare to HAT. Methods In an unmanned aerial system (UAS) context, a comparison was made among three types of three-member teams: (1) synthetic teams in which the pilot role is assigned to a synthetic teammate, (2) control teams in which the pilot was an inexperienced human, and (3) experimenter teams in which an experimenter served as an experienced pilot. Ten of each type of team participated. Measures of team performance, target processing efficiency, team situation awareness, and team verbal behaviors were analyzed. Results Synthetic teams performed as well at the mission level as control (all human) teams but processed targets less efficiently. Experimenter teams performed better across all other measures compared to control and synthetic teams. Conclusion Though there is potential for a synthetic agent to function as a full-fledged teammate, further advances in autonomy are needed to improve team-level dynamics in HAT teams. Application This research contributes to our understanding of how to make autonomy a good team player.
Opportunistic decision-making in government: concept formation, variety and explanation
Authors: 6 Perri 
Published: November 2017

The notion of opportunism is too often used loosely in policy and administrative research on executive decision-making: its various meanings are too rarely clearly distinguished. To make it useful for explanation, this article presents fresh concept formation work, clarifying the concept to recognize different kinds and degrees of opportunism. To illustrate the use of the refined concept, the article examines key decisions by British cabinets and core executives between 1945 and 1990. It proposes that neo-Durkheimian institutional theory can help to explain why different kinds of opportunism are cultivated in differently ordered administrations, so providing new insight into decision-making. Points for practitioners The article provides a framework through which public managers can identify degrees and types of opportunism among the elected politicians they serve. It will help public managers to identify risks associated with such decisions, when they are asked to execute them.
