Good practice or positive action? Using Q methodology to identify competing views on improving gender equality in academic medicine

Objectives: The number of women entering medicine has increased significantly, yet women are still under-represented at senior levels in academic medicine. To support the gender equality action plan at one School of Medicine, this study sought to (1) identify the range of viewpoints held by staff on how to address gender inequality and (2) identify attitudinal barriers to change. Design: Q methodology. 50 potential interventions representing good practice or positive action, and addressing cultural, organisational and individual barriers to gender equality, were ranked by participants according to their perception of priority. Setting: The School of Medicine at the University of Leeds, UK. Participants: Fifty-five staff members were purposively sampled to represent gender and academic pay grade. Results: Principal components analysis identified six competing viewpoints on how to address gender inequality. Four viewpoints favoured positive action interventions: (1) support careers of women with childcare commitments, (2) support progression of women into leadership roles rather than focus on women with children, (3) support careers of all women rather than just those aiming for leadership, and (4) drive change via high-level financial and strategic initiatives. Two viewpoints favoured good practice with no specific focus on women by (5) recognising merit irrespective of gender and (6) improving existing career development practice. No viewpoint was strongly associated with gender, pay grade or role; however, latent class analysis identified that female staff were more likely than male to prioritise the setting of equality targets. Attitudinal barriers to the setting of targets and other positive action initiatives were identified, and it was clear that not all staff supported positive action approaches. Conclusions: The findings and the approach have utility for those involved in gender equality work in other medical and academic institutions. However, the impact of such initiatives needs to be evaluated in the longer term

Movement-related beta oscillations show high intra-individual reliability

Oscillatory activity in the beta frequency range (15-30Hz) recorded from human sensorimotor cortex is of increasing interest as a putative biomarker of motor system function and dysfunction. Despite its increasing use in basic and clinical research, surprisingly little is known about the test-retest reliability of spectral power and peak frequency measures of beta oscillatory signals from sensorimotor cortex. Establishing that these beta measures are stable over time in healthy populations is a necessary precursor to their use in the clinic. Here, we used scalp electroencephalography (EEG) to evaluate intra-individual reliability of beta-band oscillations over six sessions, focusing on changes in beta activity during movement (Movement-Related Beta Desynchronization, MRBD) and after movement termination (Post-Movement Beta Rebound, PMBR). Subjects performed visually-cued unimanual wrist flexion and extension. We assessed Intraclass Correlation Coefficients (ICC) and between-session correlations for spectral power and peak frequency measures of movement-related and resting beta activity. Movement-related and resting beta power from both sensorimotor cortices was highly reliable across sessions. Resting beta power yielded highest reliability (average ICC=0.903), followed by MRBD (average ICC=0.886) and PMBR (average ICC=0.663). Notably, peak frequency measures yielded lower ICC values compared to the assessment of spectral power, particularly for movement-related beta activity (ICC=0.386-0.402). Our data highlight that power measures of movement-related beta oscillations are highly reliable, while corresponding peak frequency measures show greater intra-individual variability across sessions. Importantly, our finding that beta power estimates show high intra-individual reliability over time serves to validate the notion that these measures reflect meaningful individual differences that can be utilised in basic research and clinical studies

Evaluation of the Surface Urban Energy and Water balance Scheme (SUEWS) at a dense urban site in Shanghai: sensitivity to anthropogenic heat and irrigation

The Surface Urban Energy and Water balance Scheme (SUEWS) is used to investigate the impact of anthropogenic heat flux (QF) and irrigation on surface energy balance partitioning in a central business district of Shanghai. Diurnal profiles of QF are carefully derived based on city-specific hourly electricity consumption data, hourly traffic data and dynamic population density. QF is estimated to be largest in summer (mean daily peak 236 W m-2). When QF is omitted, the SUEWS sensible heat flux (QH) reproduces the observed diurnal pattern generally well, but the magnitude is underestimated compared to observations for all seasons. When QF is included, the QH estimates are improved in spring, summer and autumn, but poorer in winter indicating winter QF is overestimated. Inclusion of QF has little influence on the simulated latent heat flux (QE), but improves the storage heat flux estimates except in winter. Irrigation, both amount and frequency, has a large impact on QE. When irrigation is not considered, the simulated QE is underestimated for all seasons. The mean summer daytime QE is largely overestimated compared to observations under continuous irrigation conditions. Model results are improved when irrigation occurs with a 3-day frequency, especially in summer. Results are consistent with observed monthly out-door water use. This study highlights the importance of appropriately including the QF and irrigation in urban land surface models - terms not generally considered in many previous studies

Bacterial microevolution and the Pangenome

The comparison of multiple genome sequences sampled from a bacterial population reveals considerable diversity in both the core and the accessory parts of the pangenome. This diversity can be analysed in terms of microevolutionary events that took place since the genomes shared a common ancestor, especially deletion, duplication, and recombination. We review the basic modelling ingredients used implicitly or explicitly when performing such a pangenome analysis. In particular, we describe a basic neutral phylogenetic framework of bacterial pangenome microevolution, which is not incompatible with evaluating the role of natural selection. We survey the different ways in which pangenome data is summarised in order to be included in microevolutionary models, as well as the main methodological approaches that have been proposed to reconstruct pangenome microevolutionary history

Suitability of PSA-detected localised prostate cancers for focal therapy: Experience from the ProtecT study

This article is available through a Creative Commons Attribution-NonCommercial-Share Alike 3.0 Unported License. Copyright @ 2011 Cancer Research UK.Background: Contemporary screening for prostate cancer frequently identifies small volume, low-grade lesions. Some clinicians have advocated focal prostatic ablation as an alternative to more aggressive interventions to manage these lesions. To identify which patients might benefit from focal ablative techniques, we analysed the surgical specimens of a large sample of population-detected men undergoing radical prostatectomy as part of a randomised clinical trial. Methods: Surgical specimens from 525 men who underwent prostatectomy within the ProtecT study were analysed to determine tumour volume, location and grade. These findings were compared with information available in the biopsy specimen to examine whether focal therapy could be provided appropriately. Results: Solitary cancers were found in prostatectomy specimens from 19% (100 out of 525) of men. In addition, 73 out of 425 (17%) men had multiple cancers with a solitary significant tumour focus. Thus, 173 out of 525 (33%) men had tumours potentially suitable for focal therapy. The majority of these were small, well-differentiated lesions that appeared to be pathologically insignificant (38–66%). Criteria used to select patients for focal prostatic ablation underestimated the cancer's significance in 26% (34 out of 130) of men and resulted in overtreatment in more than half. Only 18% (24 out of 130) of men presumed eligible for focal therapy, actually had significant solitary lesions. Conclusion: Focal therapy appears inappropriate for the majority of men presenting with prostate-specific antigen-detected localised prostate cancer. Unifocal prostate cancers suitable for focal ablation are difficult to identify pre-operatively using biopsy alone. Most lesions meeting criteria for focal ablation were either more aggressive than expected or posed little threat of progression.National Institute for Health Researc

Association of the transthyretin variant V122I with polyneuropathy among individuals of African ancestry

Hereditary transthyretin-mediated (hATTR) amyloidosis is an underdiagnosed, progressively debilitating disease caused by mutations in the transthyretin (TTR) gene. V122I, a common pathogenic TTR mutation, is found in 3-4% of individuals of African ancestry in the United States and has been associated with cardiomyopathy and heart failure. To better understand the phenotypic consequences of carrying V122I, we conducted a phenome-wide association study scanning 427 ICD diagnosis codes in UK Biobank participants of African ancestry (n = 6062). Significant associations were tested for replication in the Penn Medicine Biobank (n = 5737) and the Million Veteran Program (n = 82,382). V122I was significantly associated with polyneuropathy in the UK Biobank (odds ratio [OR] = 6.4, 95% confidence interval [CI] 2.6-15.6, p = 4.2 × 10-5), which was replicated in the Penn Medicine Biobank (OR = 1.6, 95% CI 1.2-2.4, p = 6.0 × 10-3) and Million Veteran Program (OR = 1.5, 95% CI 1.2-1.8, p = 1.8 × 10-4). Polyneuropathy prevalence among V122I carriers was 2.1%, 9.0%, and 4.8% in the UK Biobank, Penn Medicine Biobank, and Million Veteran Program, respectively. The cumulative incidence of common hATTR amyloidosis manifestations (carpal tunnel syndrome, polyneuropathy, cardiomyopathy, heart failure) was significantly enriched in V122I carriers compared with non-carriers (HR = 2.8, 95% CI 1.7-4.5, p = 2.6 × 10-5) in the UK Biobank, with 37.4% of V122I carriers having at least one of these manifestations by age 75. Our findings show that V122I carriers are at increased risk of polyneuropathy. These results also emphasize the underdiagnosis of disease in V122I carriers with a significant proportion of subjects showing phenotypic changes consistent with hATTR amyloidosis. Greater understanding of the manifestations associated with V122I is critical for earlier diagnosis and treatment

War related sexual violence and it's medical and psychological consequences as seen in Kitgum, Northern Uganda: A cross-sectional study

BACKGROUND: Despite the recent adoption of the UN resolution 1820 (2008) which calls for the cessation of war related sexual violence against civilians in conflict zones, Africa continues to see some of the worst cases of war related sexual violence including the mass sexual abuse of entire rural communities particularly in the Great Lakes region. In addition to calling for a complete halt to this abuse, there is a need for the systematic study of the reproductive, surgical and psychological effects of war related sexual violence in the African socio-cultural setting.This paper examines the specific long term health consequences of war related sexual violence among rural women living in two internally displaced person's camps in Kitgum district in war affected Northern Uganda who accessed the services of an Isis-Women's International Cross Cultural Exchange (Isis-WICCE) medical intervention. METHODS: The study employed a purposive cross-sectional study design where 813 respondents were subjected to a structured interview as part of a screening procedure for an emergency medical intervention to identify respondents who required psychological, gynaecological and surgical treatment. RESULTS: Over a quarter (28.6%) of the women (n = 573) reported having suffered at least one form of war related sexual violence. About three quarters of the respondents had 'at least one gynaecological complaint' (72.4%) and 'at least one surgical complaint' (75.6%), while 69.4% had significant psychological distress scores (scores greater than or equal to 6 on the WHO SRQ-20). The factors that were significantly associated with war related sexual violence were the age group of less than or equal to 44 years, being Catholic, having suffered other war related physical trauma, and having 'at least one gynaecological complaint'. The specific gynaecological complaints significantly associated with war related sexual violence were infertility, chronic lower abdominal pain, abnormal vaginal bleeding, and sexual dysfunction. In a multivariable analysis the age group of less than or equal to 44 years, being Catholic and having 'at least one gynaecological complaint' remained significantly associated with war related sexual violence. CONCLUSION: The results from this study demonstrate that war related sexual violence is independently associated with the later development of specific gynaecological complaints

Urban signals in high-resolution weather and climate simulations: role of urban land-surface characterisation

Two urban schemes within the Joint UK Land Environment Simulator (JULES) are evaluated offline against multi-year flux observations in the densely built-up city centre of London and in suburban Swindon (UK): (i) the 1-tile slab model, used in climate simulations, (ii) the 2-tile canopy model MORUSES (Met Office–Reading Urban Surface Exchange Scheme), used for numerical weather pre- diction over the UK. Offline, both models perform better at the suburban site, where differences between the urban schemes are less pronounced due to larger vegetation fractions. At both sites, the outgoing short- and longwave radiation is more accurately represented than the turbulent heat fluxes. The seasonal varia- tions of model skill are large in London, where the sensible heat flux in autumn and winter is strongly under-predicted if the large city-centre magnitudes of anthro- pogenic heat emissions are not represented. The delayed timing of the sensible heat flux in the 1-tile model in London results in large negative bias in the morning. The partitioning of the urban surface into canyon and roof in MORUSES improves this as the roof-tile is modelled with a very low thermal inertia, but phase and amplitude of the gridbox-averaged flux critically depend on accurate knowledge of the plan-area fractions of streets and buildings. Not representing non-urban land- cover (e.g. vegetation, inland water) in London results in severely under-predicted latent heat fluxes. Control runs demonstrate that the skill of both models can be greatly improved by providing accurate land-cover and morphology information and using representative anthropogenic heat emissions, which is essential if the model output is intended to inform integrated urban services

Onstage and off: The shifting relevance of gender in women’s prisons

uncorrected proofEven though international research on men’s prisons is no longer oblivious to gender, approaches to women’s prisons have tended to be more gender-bound as a whole. Besides having informed a specific reflexive agenda of representation, the angle of gender has presided to most research issues as an analytical overall parti pris: from the gendered nature of prison regimes to the gendered character of prison cultures, socialities and ‘pains of imprisonment’. This more ‘gendercentric’ agenda is however becoming more diversified for theoretical and empirical reasons alike. These involve a recognition of the diversity of women prisoners’ experiences and identities, and an attention to a wider variety of aspects of carceral life. Drawing on field approaches to the Portuguese carceral world spanning three decades, I propose to take this debate further by focusing on contextual shifts in the actual saliency of gender as a category of identity and social life in women’s prisons.(undefined)(undefined)info:eu-repo/semantics/publishedVersio
