RESUMO

BACKGROUND: The use of e-cigarettes has been rising in the UK, with 7·7% of people aged over 16 years currently vaping daily or occasionally. Young people aged 16-24 years have the highest proportion of vapers at 11·1%. Therefore, this study investigated behaviours, attitudes, and beliefs about e-cigarettes among people aged 15-30 year in the UK. METHODS: For this cross-sectional study, we administered an online survey to a representative sample of people aged 15-30 years in the UK (based on a web panel) between Oct 1, and Nov 30, 2021. Questions related to respondent demographics; use of vaping or smoking products; motivations, attitudes, and behaviours related to vaping; and exposure to e-cigarette advertising. Ever use was described as use even "just once or twice". We used multivariable logistic regression to identify factors associated with ever e-cigarette use. FINDINGS: 1009 participants responded to the survey (mean age 23 years, 520 [51·5%] women, 470 [46.6%] men) and were included in the study. 222 (22·3%) participants vaped at least monthly, with one in ten doing it daily. Current smokers were the most likely to use e-cigarettes (453, 44·9%), followed by previous smokers (288, 28·5%) and never smokers (23, 2·3%). Of the 222 participants vaping at least monthly, 199 (89·6%) had used e-cigarettes containing nicotine. The most common reasons for vaping were having friends who used e-cigarettes (103, 46·4%) and quitting or reducing smoking (89, 40·1%). Most participants agreed that e-cigarettes are addictive (698, 75·1%), help people quitting smoking (597, 64·2%), and are bad for health (584, 62·8%). Warning labels on e-cigarettes were seen by 611 (65·7%) participants, and 489 (52·6%) had been exposed to e-cigarette advertising, especially online. Previous or current tobacco smokers were nine and 22 times more likely to use e-cigarettes than never smokers, respectively (odds ratio [OR] 8·5, 95% CI 5·2-14·0 for previous smokers and 22·3, 12·2-40·7 for current smokers). Perceiving e-cigarettes as harmful was associated with a 40% lower likelihood of vaping (OR 0·6, 0·49-0·83). INTERPRETATION: Vaping seems relatively common among people aged 15-30 years in the UK, mainly among previous and current smokers. Caution should be taken as these findings might not be generalisable to the young UK population, and cross-sectional associations might not be causal. However, perceiving e-cigarettes as harmful might reduce their use, and many users seem unaware of their potential harms, which emphasises the need for further regulation on labelling, marketing, and sales. FUNDING: National Health and Medical Council.

RESUMO

INTRODUCTION: Climate change has a disproportionate impact on women in comparison to men, and women have a key role to play in climate adaptation. However, evidence is lacking on how gender inequalities may be associated with climate vulnerability and ability to respond at country level. METHODS: This ecological study investigated the association between climate adaptation, measured by the Notre Dame Global Adaptation Initiative Country Index (ND-GAIN), and gender equality, measured by the Global Gender Gap Index (GGGI) developed by the World Economic Forum and the Gender Inequality Index (GII) developed by the United Nations. Simple linear regression was used to estimate the associations between the indices and their subdomains for 146 countries. RESULTS: There was an approximately linear association between the GGGI and climate adaptation. Each 1% increase in gender equality was associated with a 0.6% increase in the ND-GAIN score (the slope was 0.59, with a 95% confidence interval [0.33 to 0.84]). This was driven by a negative association between gender equality and vulnerability (-0.41 [-0.62 to -0.20]), and a positive association between gender equality and readiness (0.77 [0.44 to 1.10]). The strongest associations between gender equality and climate adaptation were observed for the education domain of the GGGI. There was a strong negative linear association between the GII and climate adaptation, which explained most (86%) of the between-country variation in climate adaptation. Each 1% increase in gender inequality was associated with a 0.5% decrease in the ND-GAIN score (-0.54 [-0.57 to -0.50]). The association between gender inequality and readiness was stronger than the association with vulnerability (0.41 [0.37 to 0.44] for vulnerability versus - 0.67 [-0.72 to -0.61] for readiness). CONCLUSIONS: Gender inequality, measured broadly across different domains of life, is associated with climate adaptation at country level, both in terms of vulnerability to impact and readiness to respond.

RESUMO

INTRODUCTION: Socioeconomic disparities have been shown to correlate with perinatal mortality and the incidence of type 2 diabetes. Few studies have explored the relationship between deprivation and the incidence of gestational diabetes (GDM). We aimed to identify the relationship between deprivation and incidence of GDM, after adjusting for age, BMI, and ethnicity. We also examined for relationships between deprivation and perinatal outcomes. METHODS: A retrospective cohort analysis of 23,490 pregnancies from a major National Health Service Trust in Northwest London was conducted. The 2019 English Indices of Multiple Deprivation was used to identify the deprivation rank and decile for each postcode. Birthweight centile was calculated from absolute birthweight after adjusting for ethnicity, maternal height, maternal weight, parity, sex and outcome (live birth/stillbirth). Logistic regression and Kendall's Tau were used to identify relationships between variables. RESULTS: After controlling for age, BMI & ethnicity, Index of Multiple Deprivation postcode decile was not associated with an increased risk of developing gestational diabetes. Each increase in decile of deprivation was associated with an increase in birthweight centile by 0.471 (p < 0.001). After adjusting for confounders, age was associated with a 7.1% increased GDM risk (OR: 1.076, p < 0.001); BMI increased risk by 5.81% (OR: 1.059, p < 0.001). There was no significant correlation between Index of Multiple Deprivation rank and perinatal outcomes. DISCUSSION: Our analysis demonstrates that socioeconomic deprivation was not associated with incidence of GDM or adverse perinatal outcomes. Factors such as genetic predisposition and lifestyle habits may likely play a larger role in the development of GDM compared to socioeconomic deprivation alone.

RESUMO

OBJECTIVES: To investigate changes in mean sugar content of non-alcoholic beverages (overall and sugar-sweetened beverages (SSB)) available for purchase in Australia and to compare signatories v. non-signatories of the Australian Beverages Council voluntary pledge from 2018. DESIGN: Retrospective observational study. SETTING: Australia. PARTICIPANTS: About 1500 non-alcoholic beverages per year included in the FoodSwitch Monitoring Datasets for 2015-2019. RESULTS: Overall, mean sugar content fell by 1·3 g/100 ml (17·1 %) from 7·5 g/100 ml in 2015 to 6·2 g/100 ml in 2019. SSB have accounted for about 56 % of all beverages available for purchase since 2015. Between 2015 and 2019, the sugar content of SSB dropped by about 10 % (0·8 g/100 ml). Soft drinks and milk-based drinks were the categories with the largest decrease in sugar content. The greater reduction in sugar observed for beverages overall than SSB suggests at least some of the overall decrease in sugar content is due to the appearance of new products with low or no sugar rather than reformulation. Over the same period, beverages with added non-nutritive sweeteners increased from 41 % to 44 %. The decrease in sugar content for all beverages and SSB was, in general, larger for non-signatories than signatories of the voluntary industry pledge. CONCLUSIONS: Between 2015 and 2019, the small reduction in sugar content of non-alcoholic beverages in Australia resulted from the combined effects of introducing low- or no-sugar products and reformulation of some categories of SSB. Further policy and regulatory measures are required to reap the most benefit that sugar reduction among non-alcoholic beverages can bring to population health.

RESUMO

BACKGROUND: London has the lowest smoking prevalence among pregnant women in England. However, it was unclear whether the low overall prevalence masked inequalities. This study investigated the prevalence of smoking among pregnant women in North West London stratified by ethnicity and deprivation. METHODS: Data regarding smoking status, ethnicity and deprivation were extracted from electronic health records collected by maternity services at Imperial Healthcare NHS Trust between January 2020 and August 2022. RESULTS: A total of 25 231 women were included in this study. At the time of booking of antenatal care (mean of 12 weeks), 4% of women were current smokers, 17% were ex-smokers and 78% never smokers. There were marked differences in the smoking prevalence between ethnic groups. Women of Mixed-White and Black Caribbean ethnicity and White Irish women had the highest prevalence of smoking (12 and 9%, respectively). There was an over 4-fold increase in the prevalence of smoking between the most and the least deprived groups (5.6 versus 1.3%). CONCLUSIONS: Even in a population with an overall low prevalence of smoking in pregnancy, women experiencing deprivation and from certain ethnic backgrounds have a high smoking prevalence and hence are the most likely to benefit from smoking cessation interventions.

RESUMO

BACKGROUND: The use of e-cigarettes has been rising in the UK, particularly by young people. This study investigated behaviours, attitudes and beliefs about e-cigarettes amongst 15-30-year-olds in the UK. METHODS: An online survey was administered to a sample of 1009 15-30-year-olds in the UK. RESULTS: About one in five participants currently used e-cigarettes at least monthly, with 1 in 10 using them daily. Amongst those using e-cigarettes at least monthly, 90% had used e-cigarettes containing nicotine. E-cigarettes were mainly obtained from vape shops and used at home. Having friends who used e-cigarettes and using them to help quit/reduce smoking were the most common reasons for vaping. About half of participants had been exposed to e-cigarette advertising, especially online, and warning labels on e-cigarettes. Most participants agreed that e-cigarettes are addictive (75%), help people quitting smoking (64%) and are bad for health (63%). Previous or current tobacco smokers were 9 and 22 times more likely to use e-cigarettes than never smokers, respectively. Perceiving e-cigarettes as harmful was associated with a 40% lower likelihood of use. CONCLUSION: Raising awareness on the uncertain long-term consequences of vaping and regulation of marketing and sales are crucial to protect young people in the UK.

RESUMO

BACKGROUND: Food policy is important to promote healthy and sustainable diets. However, who is responsible for developing and implementing food policy remains contentious. Therefore, this study aimed to investigate how the public attributes responsibility for food policy to governments, individuals and the private sector. METHODS: A total of 7559 respondents from seven countries [Australia (n = 1033), Canada (n = 1079), China (n = 1099), India (n = 1086), New Zealand (n = 1090), the UK (n = 1079) and the USA (n = 1093)] completed an online survey assessing perceived responsibility for 11 recommended food policies. RESULTS: Overall, preferred responsibility for the assessed food policies was primarily attributed to governments (62%), followed by the private sector (49%) and individuals (31%). Respondents from New Zealand expressed the highest support for government responsibility (70%) and those from the USA the lowest (50%). Respondents from the USA and India were most likely to nominate individuals as responsible (both 37%), while those from China were least likely (23%). The private sector had the highest attributed responsibility in New Zealand (55%) and the lowest in China and the USA (both 47%). Support for government responsibility declined with age and was higher among those on higher incomes, with a university degree, and who perceived themselves to consume a healthy diet or be in poor health. CONCLUSIONS: Across seven diverse countries, results indicate the public considers government should take primary responsibility for the assessed food policies, with modest contribution from the private sector and minority support for individual responsibility.

RESUMO

The updated NICE guidelines on tobacco recommend cost-effective and evidence-based interventions to prevent smoking initiation and promote smoking cessation across the life course. E-cigarettes are a cost-effective adjunct to support smoking cessation in adults, but their long-term effects are yet to be fully understood. Concerted efforts from healthcare and public health providers are required to reach underserved groups and hence address stark and longstanding inequalities in smoking prevalence and associated ill health in England.

RESUMO

Healthcare systems account for a substantial proportion of global carbon emissions and contribute to wider environmental degradation. This scoping review aimed to summarize the evidence currently available on incorporation of environmental and sustainability considerations into health technology assessments (HTAs) and guidelines to support the National In stitute for Health and Care Excellence and analogous bodies in other jurisdictions developing theirown methods and processes. Overall, 7,653 articles were identified, of which 24 were included in this review and split into three key areas - HTA (10 studies), healthcare guidelines (4 studies), and food and dietary guidelines (10 studies). Methodological reviews discussed the pros and cons of different approaches to integrate environmental considerations into HTAs, including adjustments to conventional cost-utility analysis (CUA), cost-benefit analysis, and multicriteria decision analysis. The case studies illustrated the challenges of putting this into practice, such as lack of disaggregated data to evaluate the impact of single technologies and difficulty in conducting thorough life cycle assessments that consider the full environmental effects. Evidence was scant on the incorporation of environmental impacts in clinical practice and public health guidelines. Food and dietary guidelines used adapted CUA based on life cycle assessments, simulation modeling, and qualitative judgments made by expert panels. There is uncertainty on how HTA and guideline committees will handle trade-offs between health and environment, especially when balancing environmental harms that fall largely on society with health benefits for individuals. Further research is warranted to enable integration of environmental considerations into HTA and clinical and public health guidelines.

RESUMO

The importance of patient and public involvement (PPI) is recognized by agencies involved in health technology assessment (HTA) and guideline development. However, a comprehensive overview of the underlying PPI principles, values, strategies, and frameworks is lacking. This scoping review aimed to summarize the available evidence on principles, values, frameworks, and strategies underpinning PPI carried out by agencies involved in HTA and guideline development. A total of twelve records were included, of which four referred to guidelines and eight to HTA. Overall, this review demonstrated a lack of consistency in the definition and application of the concepts of values and principles to PPI in the context of guideline development and HTA. There was significant overlap between values and principles, with some broad themes emerging, such as representation, transparency, relevance, equity, fairness, and reconciling different types of knowledge. Frameworks were typically based on the stages of guideline development or HTA, despite heterogeneity in how stages were labeled and described. Strategies were also mapped to the stages of guideline development and HTA and varied substantially depending on the context and setting. Both strategies and frameworks demonstrated patients and the public can be involved, albeit to a variable extent, throughout the stages of guideline development and HTA. However, frameworks often failed to explicitly link the values and principles with the HTA and guideline development stages through actionable PPI strategies. Further research is warranted to better understand the values, principles, and frameworks underpinning PPI in guideline development and HTA.

RESUMO

BACKGROUND: Randomised evidence on the efficacy of blood pressure (BP)-lowering treatment to reduce cardiovascular risk in patients with atrial fibrillation (AF) is limited. Therefore, this study aimed to compare the effects of BP-lowering drugs in patients with and without AF at baseline. METHODS AND FINDINGS: The study was based on the resource provided by the Blood Pressure Lowering Treatment Trialists' Collaboration (BPLTTC), in which individual participant data (IPD) were extracted from trials with over 1,000 patient-years of follow-up in each arm, and that had randomly assigned patients to different classes of BP-lowering drugs, BP-lowering drugs versus placebo, or more versus less intensive BP-lowering regimens. For this study, only trials that had collected information on AF status at baseline were included. The effects of BP-lowering treatment on a composite endpoint of major cardiovascular events (stroke, ischaemic heart disease or heart failure) according to AF status at baseline were estimated using fixed-effect one-stage IPD meta-analyses based on Cox proportional hazards models stratified by trial. Furthermore, to assess whether the associations between the intensity of BP reduction and cardiovascular outcomes are similar in those with and without AF at baseline, we used a meta-regression. From the full BPLTTC database, 28 trials (145,653 participants) were excluded because AF status at baseline was uncertain or unavailable. A total of 22 trials were included with 188,570 patients, of whom 13,266 (7%) had AF at baseline. Risk of bias assessment showed that 20 trials were at low risk of bias and 2 trials at moderate risk. Meta-regression showed that relative risk reductions were proportional to trial-level intensity of BP lowering in patients with and without AF at baseline. Over 4.5 years of median follow-up, a 5-mm Hg systolic BP (SBP) reduction lowered the risk of major cardiovascular events both in patients with AF (hazard ratio [HR] 0.91, 95% confidence interval [CI] 0.83 to 1.00) and in patients without AF at baseline (HR 0.91, 95% CI 0.88 to 0.93), with no difference between subgroups. There was no evidence for heterogeneity of treatment effects by baseline SBP or drug class in patients with AF at baseline. The findings of this study need to be interpreted in light of its potential limitations, such as the limited number of trials, limitation in ascertaining AF cases due to the nature of the arrhythmia and measuring BP in patients with AF. CONCLUSIONS: In this meta-analysis, we found that BP-lowering treatment reduces the risk of major cardiovascular events similarly in individuals with and without AF. Pharmacological BP lowering for prevention of cardiovascular events should be recommended in patients with AF.

RESUMO

AIM: To investigate the association between lactation and maternal risk of type 2 diabetes, including a potential graded association according to lactation duration. METHODS: A systematic review and meta-analysis of observational studies that investigated the reported association between lactation (irrespective of duration, intensity or mode) and maternal risk of type 2 diabetes was conducted. RESULTS: A total of 22 studies (17 cohort studies and five cross-sectional studies) were included in this systematic review, and 16 contributed to the meta-analysis. Studies that investigated the association of lactation with risk of type 2 diabetes in the first months after birth in women with gestational diabetes reported conflicting results. Studies with a longer follow-up showed a graded protective association for lactation and the risk of type 2 diabetes, with a potentially larger risk reduction in women with gestational diabetes than in those without gestational diabetes. Overall, ever versus never lactation was associated with a 27% lower risk of type 2 diabetes (RR 0.73, 95% CI [0.65, 0.83]). Each additional month of lactation was associated with a 1% lower risk of type 2 diabetes (RR 0.99, 95% CI [0.98, 0.99]). However, the overall quality of the studies was modest. CONCLUSIONS: Lactation is associated with a significantly reduced risk of maternal type 2 diabetes over the life course, particularly in women with gestational diabetes. The protective effect seems to increase with longer duration of lactation. Further research is warranted to understand whether this association is modified by exposure to other risk factors.

RESUMO

AIMS: Aortic valve stenosis is commonly considered a degenerative disorder with no recommended preventive intervention, with only valve replacement surgery or catheter intervention as treatment options. We sought to assess the causal association between exposure to lipid levels and risk of aortic stenosis. METHODS AND RESULTS: Causality of association was assessed using two-sample Mendelian randomization framework through different statistical methods. We retrieved summary estimations of 157 genetic variants that have been shown to be associated with plasma lipid levels in the Global Lipids Genetics Consortium that included 188 577 participants, mostly European ancestry, and genetic association with aortic stenosis as the main outcome from a total of 432 173 participants in the UK Biobank. Secondary negative control outcomes included aortic regurgitation and mitral regurgitation. The odds ratio for developing aortic stenosis per unit increase in lipid parameter was 1.52 [95% confidence interval (CI) 1.22-1.90; per 0.98 mmol/L] for low density lipoprotein (LDL)-cholesterol, 1.03 (95% CI 0.80-1.31; per 0.41 mmol/L) for high density lipoprotein (HDL)-cholesterol, and 1.38 (95% CI 0.92-2.07; per 1 mmol/L) for triglycerides. There was no evidence of a causal association between any of the lipid parameters and aortic or mitral regurgitation. CONCLUSION: Lifelong exposure to high LDL-cholesterol increases the risk of symptomatic aortic stenosis, suggesting that LDL-lowering treatment may be effective in its prevention.

RESUMO

Despite the recent developments in deep learning models, their applications in clinical decision-support systems have been very limited. Recent digitalisation of health records, however, has provided a great platform for the assessment of the usability of such techniques in healthcare. As a result, the field is starting to see a growing number of research papers that employ deep learning on electronic health records (EHR) for personalised prediction of risks and health trajectories. While this can be a promising trend, vast paper-to-paper variability (from data sources and models they use to the clinical questions they attempt to answer) have hampered the field's ability to simply compare and contrast such models for a given application of interest. Thus, in this paper, we aim to provide a comparative review of the key deep learning architectures that have been applied to EHR data. Furthermore, we also aim to: (1) introduce and use one of the world's largest and most complex linked primary care EHR datasets (i.e., Clinical Practice Research Datalink, or CPRD) as a new asset for training such data-hungry models; (2) provide a guideline for working with EHR data for deep learning; (3) share some of the best practices for assessing the "goodness" of deep-learning models in clinical risk prediction; (4) and propose future research ideas for making deep learning models more suitable for the EHR data. Our results highlight the difficulties of working with highly imbalanced datasets, and show that sequential deep learning architectures such as RNN may be more suitable to deal with the temporal nature of EHR.

RESUMO

This review explores the association between left main disease and the increased risk of perioperative stroke following coronary artery bypass grafting, specifically addressing the potential underlying mechanisms and its potential prevention. In particular, this correlation appears stronger for patients with left main disease when compared to patients with isolated triple vessel disease. Even though evidence on this topic is limited and of modest quality, there appears to be a significant association between ascending aorta atherosclerosis and coronary artery disease. Furthermore, there seems to be a relationship between the severity and extent of carotid artery stenosis and coronary artery disease. Carotid artery disease is itself associated with atherosclerosis of the ascending aorta, a well-recognised risk factor for postoperative atheroembolic stroke. The association between left main disease, ascending aorta atherosclerosis and carotid artery stenosis may reflect an increased systemic atherosclerotic burden and hence explain, at least partially, the higher risk of perioperative cerebrovascular events. Potential pre-, intra- and post-operative strategies for stroke prevention are discussed.

RESUMO

BACKGROUND: The compelling safety, efficacy and predictable effect of novel oral anticoagulants (NOACs) is driving a rapid expansion in their therapeutic indications. Management of the increasing number of patients on those new agents in the setting of emergency or trauma surgery can be challenging and the absence of specific reversal agents has been a matter of concern. This review summarises the key principles that underpin the management of those patients with a particular emphasis on the recent development of specific antidotes. FINDINGS: As of 2015, a new line of antidotes, specific for these drugs, are at different stages of their development with their release imminent. However, as NOACs are innately reversible due to their short half-life, the use of reversal agents will probably be restricted to a few exceptional cases. Post-marketing surveillance will be paramount to better clarify the role of these promising drugs. CONCLUSIONS: Management of patients on NOACs in the context of emergency or trauma surgery relies on best supportive care in combination with the blood products and/or specific antidotes as required. Familiarity with the new reversal agents is essential but further evidence on their indications, safety and efficacy as well as consensus guidelines are warranted prior to widespread adoption.

RESUMO

Obesity is a leading cause of death and disability globally. There is a higher proportion of women living with obesity than men, with differences in prevalence rates between women and men particularly staggering in low- and middle-income countries. The food environments that most people live in have been defined as 'obesogenic', characterised by easy access to energy dense, highly palatable foods with poor nutritional value. There is an established need to intervene to change food environments to prevent obesity. However, minimal successes are evident with no country set to meet the WHO goal of reducing obesity prevalence to 2010 numbers by 2025. In this review, we provide a narrative around the sex (biological)- and gender (sociocultural)-related considerations for the relationship between nutrition, interactions with the food environment and obesity risk. We provide an argument that there are gendered responses to food environments that place women at a higher risk of obesity particularly in relation to food industry influences, due to gendered roles and responsibilities in relation to paid and unpaid labour, and due to specific food security threats. This review concludes with hypotheses for addressing the obesity burden in a gender-responsive manner, with a call for gender equity to be a key component of the development, implementation and monitoring of obesity prevention focused policies going forward.

RESUMO

Many governments are failing to systematically introduce evidence-based alcohol control policies, and debate continues around issues of market freedom and personal responsibility. The aim of this international study was to assess the extent to which the public considers a range of alcohol control policies to be the responsibility of three different categories of actors: government, the private sector, and individuals. Around 1000 respondents from seven countries (Australia, Canada, China, India, New Zealand, the UK, and the US; n = 7559) completed an online survey assessing demographic characteristics, alcohol consumption status, and perceived responsibility for four alcohol harm-reduction actions relating to alcohol availability, advertising, and public education campaigns. Across the total sample and all assessed actions, governments were selected as an appropriate actor in 66 % of instances, the private sector in 39 %, and individuals in 28 %. Respondents from New Zealand were most likely to consider the actions to be government responsibility and respondents from the US the least. In relatively few instances (8 %), respondents considered the actions unworthy of attention by any actor. Across all seven countries, governments were considered to be the most appropriate actors to undertake actions relating to restricting alcohol availability, regulating alcohol advertising, and disseminating campaigns to educate the public about alcohol-related harm. The results indicate that the public may be receptive to greater intervention in these areas.

RESUMO

Women are under-represented among authors of scientific papers. Although the number of retractions has been rising over the past few decades, gender differences among authors of retracted papers remain poorly understood. Therefore, this study investigated gender differences in authorship of retracted papers in biomedical sciences available on RetractionWatch. Among 35,635 biomedical articles retracted between 1970 and 2022, including 20,849 first authors and 20,413 last authors, women accounted for 27.4% [26.8 to 28.0] of first authors and 23.5% [22.9 to 24.1] of last authors. The lowest representation of women was found for fraud (18.9% [17.1 to 20.9] for first authors and 13.5% [11.9 to 15.1] for last authors) and misconduct (19.5% [17.3 to 21.9] for first authors and 17.8% [15.7 to 20.3] for last authors). Women's representation was the highest for issues related to editors and publishers (35.1% [32.2 to 38.0] for first authors and 24.8% [22.9 to 26.8] for last authors) and errors (29.5% [28.0 to 31.0] for first authors and 22.1% [20.7 to 23.4] for last authors). Most retractions (60.9%) had men as first and last authors. Gender equality could improve research integrity in biomedical sciences.
