Nursing intervention with a gender approach in patients with arterial hypertension: a scoping review

This scoping review aims to identify and synthesize the available literature describing the use of the gender approach in research and nursing clinical practice related to hypertension. The review was conducted following the scoping review framework recommended by Arksey and O'Malley. Elements related to content were chosen following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Data were extracted using a predesigned table and were presented narratively after the content analysis. The PubMed, CINAHL, Web of Science, PsycINFO, Cochrane, Scopus, ScienceDirect and ERIC databases were consulted between March 2022 and June 2024. Reference lists from all sources and gray literature were also reviewed to identify additional publications. A total of 18 studies were finally included in this scoping review. Most of the studies (83 percent) represent gender as a biological variable (sex), and only a few of them (22 percent) analyzed psychological or social differences. In addition, several studies include unequal representations of each sex, most of them use the terms "sex" and "gender" as incorrect or interchangeable, which makes it difficult to evaluate the results from a gender perspective. There is still a substantial gap in the literature related to nurses' intervention with a gender approach in patients with hypertension. Future studies should focus on improving health interventions by considering gender to improve equality and efficiency in health outcomes associated with hypertension and other cardiovascular risk factors.

Role of Gender in Health and Disease: Methods of Reporting and Interactions with Sex and Other Factors

ABSTRACT

Sex and gender are distinct terms that must be used correctly. Data regarding sex and gender may be collected using a 2-step method that separates biological sex and self-reported gender identity. The PhenX Toolkit, funded by the National Institutes of Health (NIH), is one tool that provides investigators with recommended standard data-collection protocols. Another tool is the Diversity Minimal Item Set questionnaire. Importantly, sex and gender interact: for example, pain has both biological aspects (sex differences in electrical, ischemic, thermal, pressure, and muscle pain sensitivity) and cultural aspects (gender factors in how people report pain and how physicians understand and treat pain in patients). Gender norms, identity, and relations all impact patient care. Gender norms, for instance, may influence how a person experiences pain, gender identity may influence a person's willingness to report pain, and gender relations may influence a physician's gendered expectations in relation to a patient's gendered behaviors. Clinicians may perceive women's pain to be psychological; as a result, women may receive more nonspecific diagnoses, wait longer for treatment, and receive more antidepressants and fewer analgesics than men. Research on gender-diverse people and pain is just now emerging. Resources for methods of reporting include The Lancet, Nature, and the Sex and Gender Equity in Research (SAGER) Guidelines. We must consider all relevant factors intersecting with sex and gender, including age, disabilities, educational background, ethnicity, family configuration, geographic location, race, sexuality, social and economic status, sustainability, and more.

Needs of female outpatients with alcohol use disorder: data from an Italian study

AIMS

Alcohol use disorder (AUD) is a common mental disorder characterized by sex-gender differences (SGDs). The present study was aimed at evaluating attitudes displayed by Italian AUD treatment services towards investigating the presence of SGDs in their patients and implementing gender-specific treatments for female AUD patients.

METHODS

Potential SGDs were initially investigated in a sample of AUD outpatients, subsequently followed by a national survey on the adoption of specific interventions for female AUD outpatients.

RESULTS

The presence of SGDs was confirmed in a sample of 525 (332 men; 193 women) AUD outpatients, including a higher prevalence of anxiety and mood disorders, and episodes of violence and trauma among female AUD outpatients compared to males. Despite the presence of these SGDs, only <20% of a total of 217 Italian AUD treatment services reported the implementation of specific strategies for female AUD outpatients. The majority of services (94%) reported investigating episodes of violence and/or trauma, largely resorting to specific procedures only when these issues were detected.

CONCLUSIONS

Our findings confirm the presence of SGDs among AUD outpatients, including a higher prevalence of anxiety and mood disorders and episodes of violence and trauma among females compared with males. However, only a small number of services have adopted a gender medicine approach in AUD treatment. These results underline the urgency of investigating the specific needs of female, male, and non-binary AUD patients in order to personalize and enhance the effectiveness and appeal of AUD treatment.

Sex-Gender Differences Are Completely Neglected in Treatments for Neuropathic Pain

As sex-gender differences have been described in the responses of patients to certain medications, we hypothesized that the responses to medications recommended for neuropathic pain may differ between men and women. We conducted a literature review to identify articles reporting potential sex-gender differences in the efficacy and safety of these medications. Only a limited number of studies investigated potential sex-gender differences. Our results show that women seem to achieve higher blood concentrations than men during treatment with amitriptyline, nortriptyline, duloxetine, venlafaxine, and pregabalin. Compared to men, higher rates of women develop side effects during treatment with gabapentin, lidocaine, and tramadol. Globally, the sex-gender differences would suggest initially administering smaller doses of these medications to women with neuropathic pain compared to those administered to men. However, most of these differences have been revealed by studies focused on the treatment of other diseases (e.g., depression). Studies focused on neuropathic pain have overlooked potential sex-gender differences in patient responses to medications. Despite the fact that up to 60% of patients with neuropathic pain fail to achieve an adequate response to medications, the potential role of sex-gender differences in the efficacy and safety of pharmacotherapy has not adequately been investigated. Targeted studies should be implemented to facilitate personalized treatments for neuropathic pain.

Protected characteristics reported in pulmonary rehabilitation: a scoping review

BACKGROUND

An individual's characteristics are reported to influence access, completion and outcomes of pulmonary rehabilitation and may contribute to health inequalities. Many countries have policies to promote equity among individuals' characteristics, including the UK Equality Act 2010 which lists nine protected characteristics (age, disability, gender reassignment, marriage and civil partnership, pregnancy and maternity, race, religion or belief, sex and sexual orientation).

OBJECTIVES

To describe the extent to which UK Equality Act 2010 protected characteristics have been collected and reported in UK studies and audits of pulmonary rehabilitation.

METHODS

A scoping review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews guidelines was conducted using five databases. UK studies and audits collecting data on pulmonary rehabilitation from 1 October 2010 (date of Equality Act 2010 inception) were eligible. The protected characteristics collected and how they were reported were extracted.

RESULTS

Out of 45 included studies and audits (41 studies and four audits), 98% (k=44) reported age. Sex was reported in 40% (k=18), and 20% (k=9) reported gender with only male and female categories. Half (50%, k=2) of audits reported gender with male, female and transgender categories. Race was reported through ethnicity in 2% (k=1) of studies and 75% (k=3) of audits. No studies or audits explicitly reported disability, but all reported measures indicating disease severity (e.g. forced expiratory volume in 1 s % predicted: 67%, k=30). No studies or audits reported marriage and civil partnership, pregnancy and maternity, religion or belief or sexual orientation.

CONCLUSIONS

Protected characteristics are not commonly reported or are inconsistently reported in UK pulmonary rehabilitation studies and audits. Without reporting these characteristics, health inequalities in pulmonary rehabilitation will remain unclear.

Sex/gender differences in the associations between adverse childhood experiences and intimate partner violence with mental disorders

Sex and gender differences exist in mental and substance use disorders (MSUDs). Studies examining the moderating effects of sex/gender on MSUDs may help understand these differences. This national study explored whether sex/gender moderated (1) the associations between adverse childhood experience (ACEs; i.e., child abuse, child neglect, and child household dysfunction) and intimate partner violence (IPV) with MSUDs and (2) more associations with past year than lifetime MSUDs or mental (i.e., mood disorder, anxiety disorder, and posttraumatic stress disorder) than substance use disorders (i.e., alcohol use disorder and nicotine dependence). Data was used from participants in the National Epidemiologic Survey on Alcohol and Related Conditions. Logistic regression tested the main effects of ACEs, IPV, and sex/gender on five, past-year and lifetime MSUDs along with the ACE-sex/gender and IPV-sex/gender interactions. Sex/gender moderated 60% of the ACEs-MSUD and IPV-MSUD associations and more associations with lifetime (54%) than past year MSUDs (46%) and substance use (94%) than mental disorders (38%). For nearly half of the moderated associations, ACEs and IPV were associated with greater odds of MSUDs for males. Males who experienced IPV had greater odds of lifetime mood, anxiety, and alcohol use disorders than females. This study advances sex and gender informed research.

Foregrounding women and household dynamics to inform Article 17: a qualitative description analysis of tobacco farming households in Mozambique

PURPOSE

This paper examines the intrahousehold dynamics between women and men present in tobacco farming households in Mozambique. Attention to the experiences and realities of the smallholder farmers is crucial for understanding approaches to alternative livelihoods. Intrahousehold dynamics can provide important insights into how these households and their members view tobacco production and engage with the political economy of tobacco farming, how they make decisions, and the rationale and values behind these decisions.

METHODS

Data were collected through single-gender focus group discussions (n=8) with 108 participants (men=57, women=51). Analysis was informed by a qualitative description methodology. This research presents a gender-based analysis examining the perspectives, roles, decision-making processes and desires of female and male tobacco farmers in four key tobacco-growing districts in Mozambique.

FINDINGS

Throughout this paper, women are found to hold leverage and influence in tobacco farming households, and this leverage is in part gained via the necessity of women's unpaid labour in achieving profitability in tobacco farming. Both women and men are also found to strongly desire and pursue the well-being of the household.

CONCLUSION

Women hold agency within tobacco-growing households and participate in decision-making processes regarding tobacco agriculture. Women should be included in future tobacco control policies and programmes pertaining to Article 17.

Sex and gender in infection and immunity: addressing the bottlenecks from basic science to public health and clinical applications

Although sex and gender are recognized as major determinants of health and immunity, their role is rarely considered in clinical practice and public health. We identified six bottlenecks preventing the inclusion of sex and gender considerations from basic science to clinical practice, precision medicine and public health policies. (i) A terminology-related bottleneck, linked to the definitions of sex and gender themselves, and the lack of consensus on how to evaluate gender. (ii) A data-related bottleneck, due to gaps in sex-disaggregated data, data on trans/non-binary people and gender identity. (iii) A translational bottleneck, limited by animal models and the underrepresentation of gender minorities in biomedical studies. (iv) A statistical bottleneck, with inappropriate statistical analyses and results interpretation. (v) An ethical bottleneck posed by the underrepresentation of pregnant people and gender minorities in clinical studies. (vi) A structural bottleneck, as systemic bias and discriminations affect not only academic research but also decision makers. We specify guidelines for researchers, scientific journals, funding agencies and academic institutions to address these bottlenecks. Following such guidelines will support the development of more efficient and equitable care strategies for all.

Cognitive fitness modulates gender differences in sleep and mental health among competitive athletes under chronic stress

Objectives: Mental fitness is increasingly considered a key component of an athlete’s competitive arsenal. Active domains of mental fitness include cognitive fitness, sleep, and mental health; and these domains can differ between men and women athletes. Our study investigated the associations of cognitive fitness and gender to sleep and mental health, and the interaction between cognitive fitness and gender on sleep and mental health, in competitive athletes during the COVID-19 pandemic.

Methods: 82 athletes competing at levels from regional/state to international (49% women, M-age = 23.3 years) completed measures of self-control, intolerance of uncertainty, and impulsivity (together representing constructs of cognitive fitness), items about sleep (total sleep time, sleep latency, and mid-sleep time on free days) and a measure of mental health (depression, anxiety, and stress).

Results: Women athletes reported lower self-control, higher intolerance of uncertainty, and higher positive urgency impulsivity compared with men athletes. Women reported sleeping later, but this gender difference disappeared after controlling for cognitive fitness. Women athletes—after controlling for cognitive fitness—reported higher depression, anxiety, and stress. Across genders, higher self-control was associated with lower depression, and lower intolerance of uncertainty was associated with lower anxiety. Higher sensation seeking was associated with lower depression and stress, and higher premeditation was associated with greater total sleep time and anxiety. Higher perseverance was associated with higher depression for men—but not women—athletes.

Conclusion: Women athletes in our sample reported poorer cognitive fitness and mental health compared to men athletes. Most cognitive fitness factors protected competitive athletes under chronic stress, but some exposed them to poorer mental health. Future work should examine the sources of gender differences. Our findings suggest a need to develop tailored interventions aimed at improving athlete wellbeing, with a particular focus on women athletes.

Sex and gender differences in the use of oral anticoagulants for non-valvular atrial fibrillation: A population-based cohort study in primary health care in catalonia

Objectives: To describe the sex and gender differences in the treatment initiation and in the socio-demographic and clinical characteristics of all patients initiating an oral anticoagulant (OAC), and the sex and gender differences in prescribed doses and adherence and persistence to the treatment of those receiving direct oral anticoagulants (DOAC). Material and methods: Cohort study including patients with non-valvular atrial fibrillation (NVAF) who initiated OAC in 2011-2020. Data proceed from SIDIAP, Information System for Research in Primary Care, in Catalonia, Spain. Results: 123,250 people initiated OAC, 46.9% women and 53.1% men. Women were older and the clinical characteristics differed between genders. Women had higher risk of stroke than men at baseline, were more frequently underdosed with DOAC and discontinued the DOAC less frequently than men. Conclusion: We described the dose adequacy of patients receiving DOAC, finding a high frequency of underdosing, and significantly higher in women in comparison with men. Adherence was generally high, only with higher levels in women for rivaroxaban. Persistence during the first year of treatment was also high in general, being significantly more persistent women than men in the case of dabigatran and edoxaban. Dose inadequacy, lack of adherence and of persistence can result in less effective and safe treatments. It is necessary to conduct studies analysing sex and gender differences in health and disease.

A Narrative Review of Sex and Gender Differences in Sleep Disordered Breathing: Gaps and Opportunities

INTRODUCTION

Sleep disordered breathing (SDB) is a common condition, associated with multiple comorbidities including cardiovascular and metabolic disease. It has been previously established that SDB is more prevalent in men than women, shifting the literature's focus away from the latter population. As such, underdiagnosis, and thus undertreatment, of SDB in women exists.

METHODS

To establish the differences in prevalence, clinical presentation, and pathophysiology of SDB between the two sexes, a narrative review of the current literature was performed.

RESULTS

Rates of SDB are higher among men, likely driven by differences in symptom presentation between men and women, with women presenting with more "atypical" symptoms, and lack of sensitivity in SDB screening tools to detect SDB in women. In addition to the cardiovascular risks of SDB, women with SDB may have worse quality of life, higher prevalence of insomnia, and respiratory issues.

DISCUSSION

More research is needed to better define the unique pathophysiology and clinical presentation of SDB in women. In addition, an increased awareness among health care providers and the lay public of the SDB-specific sex and gender differences will serve to minimize disparities in identification and treatment of SDB in women.

Sex and Gender in Lung Disease and Sleep Disorders: A State-of-the-Art Review

The terms sex and gender often are used interchangeably, but have specific meaning when it comes to their effects on lung disease. Ample evidence is now available that sex and gender affect the incidence, susceptibility, presentation, diagnosis, and severity of many lung diseases. Some conditions are more prevalent in women, such as asthma. Other conditions are seen almost exclusively in women, like lymphangioleiomyomatosis. Some life stages-such as pregnancy-are unique to women and can affect the onset and course of lung disease. Clinical presentation may differ as well, such as higher number of exacerbations experienced by women with COPD and greater cardiovascular morbidity in women with sleep-disordered breathing. In addition, response to therapy and medication safety may also differ by sex, and yet, pharmacogenomic factors often are not addressed adequately in clinical trials. Various aspects of lung and sleep biology and pathobiology are impacted by female sex and female reproductive transitions. Differential gene expression or organ development can be impacted by these biological differences. Understanding these differences is the first step in moving toward precision medicine for women. This article is a state-of-the-art review of specific effects of sex and gender focused on epidemiology, disease presentation, risk factors, and management of lung diseases. Pathobiological mechanisms explaining sex differences in these diseases are beyond the scope of this article. We review the literature and focus on recent guidelines about using sex and gender in research. We also review sex and gender differences in lung diseases.

Sex and Gender Health Educational Tenets: A Report from the 2020 Sex and Gender Health Education Summit

Background: Sex as a biological variable and gender as a sociocultural variable influence many health conditions and outcomes. However, they have not been incorporated systematically into education across health professions. Methods: Areas of knowledge and abilities that apply to sex and gender education across health professions were summarized from the 2015 and 2018 Sex and Gender Health Education Summits. Results: Using this summary, draft tenets were developed by facilitated interprofessional discussion groups at the 2020 Summit, and then reviewed, edited, and refined by a writing group who recommended four tenets that health care professionals should be able to do: (1) demonstrate knowledge of sex and gender specific health (SGSH), (2) evaluate literature and the conduct of research for incorporation of sex and gender, (3) incorporate sex and gender considerations into clinical decision making, and (4) demonstrate patient advocacy with respect to sex and gender. Conclusion: These tenets provide the framework for collaborative interprofessional education about SGSH. Individual professions can also use the tenets to develop practice-specific competencies, competency statements, and/or assessment benchmarks within the structures of their respective accrediting bodies to advance the health of women, men, and sex and gender minority persons. Interprofessional collaborations are key for sharing best practices in development, curricular integration, and dissemination.

Considering sex and gender in Epidemiology: a challenge beyond terminology. From conceptual analysis to methodological strategies

Background

Epidemiologists need tools to measure effects of gender, a complex concept originating in the social sciences which is not easily operationalized in the discipline. Our aim is to clarify useful concepts, measures, paths, effects, and analytical strategies to explore mechanisms of health difference between men and women.

Methods

We reviewed concepts to clarify their definitions and limitations for their translation into usable measures in Epidemiology. Then we conducted methodological research using a causal framework to propose methodologically appropriate strategies for measuring sex and gender effects in health.

Results

(1) Concepts and measures. We define gender as a set of norms prescribed to individuals according to their attributed-at-birth sex. Gender pressure creates a systemic gap, at population level, in behaviors, activities, experiences, etc., between men and women. A pragmatic individual measure of gender would correspond to the level at which an individual complies with a set of elements constituting femininity or masculinity in a given population, place and time. (2) Main analytical strategy. Defining and measuring gender are not sufficient to distinguish the effects of sex and gender on a health outcome. We should also think in terms of mechanisms, i.e., how the variables are linked together, to define appropriate analytical strategies. A causal framework can help us to conceptualize “sex” as a “parent” of a gender or gendered variable. This implies that we cannot interpret sex effects as sexed mechanisms, and that we can explore gendered mechanisms of sex-differences by mediation analyses. (3) Alternative strategy. Gender could also be directly examined as a mechanism, rather than through a variable representing its realization in the individual, by approaching it as an interaction between sex and social environment.

Conclusions

Both analytical strategies have limitations relative to the impossibility of reducing a complex concept to a single or a few measures, and of capturing the entire effect of the phenomenon of gender. However, these strategies could lead to more accurate analyses of the mechanisms underlying health differences between men and women.

A pragmatic individual measure of individual gender would correspond to the level at which an individual complies with a set of elements constituting femininity or masculinity in a given population, place and time

Comparing outcomes by sex and gender is not sufficient, and even misleading, to understand the mechanisms underlying biological and health differences between men and women

Causal analysis framework is a powerful tool for refining hypotheses and identifying the effects that can and should be estimated to meet the objectives

Gender could also be measured at the populational-level as an interaction between sex and environment, which would be more compatible with the sociological concept of gender

An Evaluation of Sex- and Gender-Based Analyses in Oncology Clinical Trials

BACKGROUND

The objective of this study was to evaluate whether sex- and gender-based analyses and proper sex- and gender-terminology were used in oncology trials leading to regulatory drug approval.

METHODS

The Food and Drug Administration (FDA) Hematology/Oncology Approvals and Safety Notifications page was used to identify all anti-cancer therapies that received FDA approval between 2012 and 2019. The trials used to support FDA-drug approval were collected along with all available supplemental tables and study protocols. Documents were reviewed to determine if there was a plan to analyze results according to sex and gender and to determine if consistent sex and gender terminology were used.

RESULTS

128 randomized-controlled trials were identified corresponding to a cancer medicine which received FDA-approval. No study specified how sex and gender were collected or analyzed. No study reported any information on the gender of participants. Sex and gender terminology was used inconsistently at least once in 76% (97/128) of studies. Among the 102 trials for non-sex-specific cancer sites, 89% (91/102) presented disaggregated survival outcome data by sex. No study presented disaggregated toxicity data by sex or gender.

CONCLUSION

The majority of pivotal clinical trials in oncology fail to account for the important distinction between sex and gender and conflate sex and gender terminology. More rigor in designing clinical trials to include sex and gender based analyses and more care in using sex and gender terms in the cancer literature is needed. These efforts are essential to improve the reproducibility, generalizability, and inclusiveness of cancer research.

Sexual Dimorphism in Cardiovascular Biomarkers: Clinical and Research Implications

Sex-based differences in cardiovascular disease presentation, diagnosis, and response to therapies are well established, but mechanistic understanding and translation to clinical applications are limited. Blood-based biomarkers have become an important tool for interrogating biologic pathways. Understanding sexual dimorphism in the relationship between biomarkers and cardiovascular disease will enhance our insights into cardiovascular disease pathogenesis in women, with potential to translate to improved individualized care for men and women with or at risk for cardiovascular disease. In this review, we examine how biologic sex associates with differential levels of blood-based biomarkers and influences the effect of biomarkers on disease outcomes. We further summarize key differences in blood-based cardiovascular biomarkers along central biologic pathways, including myocardial stretch/injury, inflammation, adipose tissue metabolism, and fibrosis pathways in men versus women. Finally, we present recommendations for leveraging our current knowledge of sex differences in blood-based biomarkers for future research and clinical innovation.

Sex and gender considerations in reporting guidelines for health research: a systematic review

Background

Despite growing recognition of the importance of sex and gender considerations in health research, they are rarely integrated into research design and reporting. We sought to assess the integration of sex, as a biological attribute, and gender, as a socially constructed identity, in published reporting guidelines.

Methods

We conducted a systematic review of published reporting guidelines listed on the EQUATOR website (www.equator-nework.org) from inception until December 2018. We selected all reporting guidelines (original and extensions) listed in the EQUATOR library. We used EndNote Citation Software to build a database of the statements of each guideline identified as a "full bibliographic reference" and retrieved the full texts. Reviewers independently extracted the data on use of sex and gender terms from the checklist/abstract/main text of guidelines. Data were analyzed using descriptive statistics and narrative synthesis.

Results

A total of 407 reporting guidelines were included; they were published between 1995 and 2018. Of the 407 guidelines, 235 (57.7%) mentioned at least one of the sex- and gender-related words. In the checklist of the reporting guidelines (n = 363), “sex” and “gender” were mentioned in 50 (13.8%) and 40 (11%), respectively. Only one reporting guideline met our criteria (nonbinary, appropriate categorization, and non-interchangeability) for correct use of sex and gender concepts. Trends in the use of "sex" and "gender" in the checklists showed that the use of “sex” only started in 2003, while “gender” has been in use since 1996.

Conclusions

We assessed the integration of sex and gender in reporting guidelines based on the use of sex- and gender-related words. Our findings showed a low use and integration of sex and gender concepts and their incorrect use. Authors of reporting guidelines should reduce this gap for a better use of research knowledge.

Omission of sex and gender considerations is a recurring deficiency in research design and reporting

Integration of sex and gender considerations in health research reporting guidelines is very low

Three criteria were used to assess correct use of sex and gender concepts

Only one reporting guideline met the three criteria

A call to action is made to address these deficiencies

The Person's Care Requires a Sex and Gender Approach

There is an urgent need to optimize pharmacology therapy with a consideration of high interindividual variability and economic costs. A sex-gender approach (which considers men, women, and people of diverse gender identities) and the assessment of differences in sex and gender promote global health, avoiding systematic errors that generate results with low validity. Care for people should consider the single individual and his or her past and present life experiences, as well as his or her relationship with care providers. Therefore, intersectoral and interdisciplinary studies are urgently required. It is desirable to create teams made up of men and women to meet the needs of both. Finally, it is also necessary to build an alliance among regulatory and ethic authorities, statistics, informatics, the healthcare system and providers, researchers, the pharmaceutical and diagnostic industries, decision makers, and patients to overcome the gender gap in medicine and to take real care of a person in an appropriate manner.

Toward an inclusive digital health system for sexual and gender minorities in Canada

Most digital health systems (DHS) are unable to capture gender, sex, and sexual orientation (GSSO) data beyond a single binary attribute with female and male options. This binary system discourages access to preventative screening and gender-affirming care for sexual and gender minority (SGM) people. We conducted this 1-year multi-method project and cocreated an action plan to modernize GSSO information practices in Canadian DHS. The proposed actions are to: (1) Envisage an equity- and SGM-oriented health system; (2) Engage communities and organizations to modernize GSSO information practices in DHS; (3) Establish an inclusive GSSO terminology; (4) Enable DHS to collect, use, exchange, and reuse standardized GSSO data; (5) Integrate GSSO data collection and use within organizations; (6) Educate staff to provide culturally competent care and inform patients on the need for GSSO data; and (7) Establish a central hub to coordinate efforts.

An Overview of Sex and Gender in Pulmonary and Critical Care Medicine

Disparities in health care have risen to the forefront of medicine in the past several years. One of the most notable disparities in the research and delivery of health care relates to sex and gender. Sex and gender affect the epidemiology, pathophysiology, and outcomes of disease and social determinants of health and access to medical care. This article discusses some of the history of considering sex as a biologic variable in medical research and clinical care. It also clarifies the definitions and terminology necessary for understanding the biologic and social underpinnings of sex and gender.

Just a Reflection: Does Drug Repurposing Perpetuate Sex-Gender Bias in the Safety Profile?

Vaccines constitute a strategy to reduce the burden of COVID-19, but the treatment of COVID-19 is still a challenge. The lack of approved drugs for severe COVID-19 makes repurposing or repositioning of approved drugs a relevant approach because it occurs at lower costs and in a shorter time. Most preclinical and clinical tests, including safety and pharmacokinetic profiles, were already performed. However, infective and inflammatory diseases such as COVID-19 are linked with hypoalbuminemia and downregulation of both phase I and phase II drug-metabolizing enzymes and transporters, which can occur in modifications of pharmacokinetics and consequentially of safety profiles. This appears to occur in a sex- and gender-specific way because of the sex and gender differences present in the immune system and inflammation, which, in turn, reflect on pharmacokinetic parameters. Therefore, to make better decisions about drug dosage regimens and to increases the safety profile in patients suffering from infective and inflammatory diseases such as COVID-19, it is urgently needed to study repurposing or repositioning drugs in men and in women paying attention to pharmacokinetics, especially for those drugs that are previously scarcely evaluated in women.

Ensuring that biomedical AI benefits diverse populations

Artificial Intelligence (AI) can potentially impact many aspects of human health, from basic research discovery to individual health assessment. It is critical that these advances in technology broadly benefit diverse populations from around the world. This can be challenging because AI algorithms are often developed on non-representative samples and evaluated based on narrow metrics. Here we outline key challenges to biomedical AI in outcome design, data collection and technology evaluation, and use examples from precision health to illustrate how bias and health disparity may arise in each stage. We then suggest both short term approaches-more diverse data collection and AI monitoring-and longer term structural changes in funding, publications, and education to address these challenges.

Sex differences in inflammatory markers in patients hospitalized with COVID-19 infection: Insights from the MGH COVID-19 patient registry

Background

Men are at higher risk for serious complications related to COVID-19 infection than women. More robust immune activation in women has been proposed to contribute to decreased disease severity, although systemic inflammation has been associated with worse outcomes in COVID-19 infection. Whether systemic inflammation contributes to sex differences in COVID-19 infection is not known.

Study design and methods

We examined sex differences in inflammatory markers among 453 men (mean age 61) and 328 women (mean age 62) hospitalized with COVID-19 infection at the Massachusetts General Hospital from March 8 to April 27, 2020. Multivariable linear regression models were used to examine the association of sex with initial and peak inflammatory markers. Exploratory analyses examined the association of sex and inflammatory markers with 28-day clinical outcomes using multivariable logistic regression.

Results

Initial and peak CRP were higher in men compared with women after adjustment for baseline differences (initial CRP: ß 0.29, SE 0.07, p = 0.0001; peak CRP: ß 0.31, SE 0.07, p<0.0001) with similar findings for IL-6, PCT, and ferritin (p<0.05 for all). Men had greater than 1.5-greater odds of dying compared with women (OR 1.71, 95% CI 1.04–2.80, p = 0.03). Sex modified the association of peak CRP with both death and ICU admission, with stronger associations observed in men compared with women (death: OR 9.19, 95% CI 4.29–19.7, p <0.0001 in men vs OR 2.81, 95% CI 1.52–5.18, p = 0.009 in women, P_interaction = 0.02).

Conclusions

In a sample of 781 men and women hospitalized with COVID-19 infection, men exhibited more robust inflammatory activation as evidenced by higher initial and peak inflammatory markers, as well as worse clinical outcomes. Better understanding of sex differences in immune responses to COVID-19 infection may shed light on the pathophysiology of COVID-19 infection.

A rapid review of gender, sex, and sexual orientation documentation in electronic health records

Objective

The lack of precise and inclusive gender, sex, and sexual orientation (GSSO) data in electronic health records (EHRs) is perpetuating inequities of sexual and gender minorities (SGM). We conducted a rapid review on how GSSO documentation in EHRs should be modernized to improve the health of SGM.

Materials and Methods

We searched MEDLINE from 2015 to 2020 with terms for gender, sex, sexual orientation, and electronic health/medical records. Only literature reviews, primary studies, and commentaries from peer-reviewed journals in English were included. Two researchers screened citations and reviewed articles with help from a third to reach consensus. Covidence, Excel, and Atlas-TI were used to track articles, extract data, and synthesize findings, respectively.

Results

Thirty-five articles were included. The 5 themes to modernize GSSO documentation in EHRs were (1) creating an inclusive, culturally competent environment with precise terminology and standardized data collection; (2) refining guidelines for identifying and matching SGM patients with their care needs; (3) improving patient-provider relationships by addressing patient rights and provider competencies; (4) recognizing techno-socio-organizational aspects when implementing GSSO in EHRs; and (5) addressing invisibility of SGM by expanding GSSO research.

Conclusions

The literature on GSSO documentation in EHRs is expanding. While this trend is encouraging, there are still knowledge gaps and practical challenges to enabling meaningful changes, such as organizational commitments to ensure affirming environments, and coordinated efforts to address technical, organizational, and social aspects of modernizing GSSO documentation. The adoption of an inclusive EHR to meet SGM needs is a journey that will evolve over time.

"You Can't Ignore a Number This Big": Gender, Risk, and Responsibility in Online Advocacy for Women's Brain Health

Alzheimer's disease affects more women than men and has therefore been highlighted as a women's issue. However, there is much debate regarding the nature of this gap, with some studies pointing to sex/gender differences in longevity to explain the disparity. Against this background of empirical uncertainty, we ask how online women's brain health campaigns position women as specifically at risk of developing the disease. Using a multimodal approach, we examine how these platforms relate womanhood to risk, prevention, and responsibility. Four main themes emerged: risk quantification, risk management, risk dispersion, and the gendering of risk. We confirm previous studies that identified a dual discourse in which Alzheimer's is represented as both a catastrophic threat and as a fate that individuals can and must prevent. We find that both constructions are intensified on women-oriented platforms compared with nonspecific websites. Ethical implications of the individualization and gendering of risk and responsibility are discussed.

Gender-related variables for health research

Background

In this paper, we argue for Gender as a Sociocultural Variable (GASV) as a complement to Sex as a Biological Variable (SABV). Sex (biology) and gender (sociocultural behaviors and attitudes) interact to influence health and disease processes across the lifespan—which is currently playing out in the COVID-19 pandemic. This study develops a gender assessment tool—the Stanford Gender-Related Variables for Health Research—for use in clinical and population research, including large-scale health surveys involving diverse Western populations. While analyzing sex as a biological variable is widely mandated, gender as a sociocultural variable is not, largely because the field lacks quantitative tools for analyzing the influence of gender on health outcomes.

Methods

We conducted a comprehensive review of English-language measures of gender from 1975 to 2015 to identify variables across three domains: gender norms, gender-related traits, and gender relations. This yielded 11 variables tested with 44 items in three US cross-sectional survey populations: two internet-based (N = 2051; N = 2135) and a patient-research registry (N = 489), conducted between May 2017 and January 2018.

Results

Exploratory and confirmatory factor analyses reduced 11 constructs to 7 gender-related variables: caregiver strain, work strain, independence, risk-taking, emotional intelligence, social support, and discrimination. Regression analyses, adjusted for age, ethnicity, income, education, sex assigned at birth, and self-reported gender identity, identified associations between these gender-related variables and self-rated general health, physical and mental health, and health-risk behaviors.

Conclusion

Our new instrument represents an important step toward developing more comprehensive and precise survey-based measures of gender in relation to health. Our questionnaire is designed to shed light on how specific gender-related behaviors and attitudes contribute to health and disease processes, irrespective of—or in addition to—biological sex and self-reported gender identity. Use of these gender-related variables in experimental studies, such as clinical trials, may also help us understand if gender factors play an important role as treatment-effect modifiers and would thus need to be further considered in treatment decision-making.

An Environmental Scan of Sex and Gender in Electronic Health Records: Analysis of Public Information Sources

Background

Historically, the terms sex and gender have been used interchangeably as a binary attribute to describe a person as male or female, even though there is growing recognition that sex and gender are distinct concepts. The lack of sex and gender delineation in electronic health records (EHRs) may be perpetuating the inequities experienced by the transgender and gender nonbinary (TGNB) populations.

Objective

This study aims to conduct an environmental scan to understand how sex and gender are defined and implemented in existing Canadian EHRs and current international health information standards.

Methods

We examined public information sources on sex and gender definitions in existing Canadian EHRs and international standards communities. Definitions refer to data element names, code systems, and value sets in the descriptions of EHRs and standards. The study was built on an earlier environment scan by Canada Health Infoway, supplemented with sex and gender definitions from international standards communities. For the analysis, we examined the definitions for clarity, consistency, and accuracy. We also received feedback from a virtual community interested in sex-gender EHR issues.

Results

The information sources consisted of public website descriptions of 52 databases and 55 data standards from 12 Canadian entities and 10 standards communities. There are variations in the definition and implementation of sex and gender in Canadian EHRs and international health information standards. There is a lack of clarity in some sex and gender concepts. There is inconsistency in the data element names, code systems, and value sets used to represent sex and gender concepts across EHRs. The appropriateness and adequacy of some value options are questioned as our societal understanding of sexual health evolves. Outdated value options raise concerns about current EHRs supporting the provision of culturally competent, safe, and affirmative health care. The limited options also perpetuate the inequities faced by the TGNB populations. The expanded sex and gender definitions from leading Canadian organizations and international standards communities have brought challenges in how to migrate these definitions into existing EHRs. We proposed 6 high-level actions, which are to articulate the need for this work, reach consensus on sex and gender concepts, reach consensus on expanded sex and gender definitions in EHRs, develop a coordinated action plan, embrace EHR change from socio-organizational and technical aspects to ensure success, and demonstrate the benefits in tangible terms.

Conclusions

There are variations in sex and gender concepts across Canadian EHRs and the health information standards that support them. Although there are efforts to modernize sex and gender concept definitions, we need decisive and coordinated actions to ensure clarity, consistency, and competency in the definition and implementation of sex and gender concepts in EHRs. This work has implications for addressing the inequities of TGNB populations in Canada.

Development of the Gender, Sex, and Sexual Orientation ontology: Evaluation and workflow

OBJECTIVE

The study sought to create an integrated vocabulary system that addresses the lack of standardized health terminology in gender and sexual orientation.

MATERIALS AND METHODS

We evaluated computational efficiency, coverage, query-based term tagging, randomly selected term tagging, and mappings to existing terminology systems (including ICD (International Classification of Diseases), DSM (Diagnostic and Statistical Manual of Mental Disorders ), SNOMED (Systematized Nomenclature of Medicine), MeSH (Medical Subject Headings), and National Cancer Institute Thesaurus).

RESULTS

We published version 2 of the Gender, Sex, and Sexual Orientation (GSSO) ontology with over 10 000 entries with definitions, a readable hierarchy system, and over 14 000 database mappings. Over 70% of terms had no mapping in any other available ontology.

DISCUSSION

We created the GSSO and made it publicly available on the National Center for Biomedical Ontology BioPortal and on GitHub. It includes clarifications on over 200 slang terms, 190 pronouns with linked example usages, and over 200 nonbinary and culturally specific gender identities.

CONCLUSIONS

Gender and sexual orientation continue to represent crucial areas of medical practice and research with evolving terminology. The GSSO helps address this gap by providing a centralized data resource.

Sex-Related Differences in the Effects of Sports-Related Concussion: A Review

Sports-related concussion is a serious health challenge, and females are at higher risk of sustaining a sports-related concussion compared to males. Although there are many studies that investigate outcomes following concussion, females remain an understudied population, despite representing a large proportion of the organized sports community. In this review, we provide a summary of studies that investigate sex-related differences in outcome following sports-related concussion. Moreover, we provide an introduction to the methods used to study sex-related differences after sports-related concussion, including common clinical and cognitive measures, neuroimaging techniques, as well as biomarkers. A literature search inclusive of articles published to March 2020 was performed using PubMed. The studies were reviewed and discussed with regard to the methods used. Findings from these studies remain mixed with regard to the effect of sex on clinical symptoms, concussion-related alterations in brain structure and function, and recovery trajectories. Nonetheless, there is initial evidence to suggest that sex-related differences following concussion are important to consider in efforts to develop objective biomarkers for the diagnosis and prognosis of concussion. Additional studies on this topic are, however, clearly needed to improve our understanding of sex-related differences following concussion, as well as to understand their neurobiological underpinnings. Such studies will help pave the way toward more personalized clinical management and treatment of sports-related concussion.

Faculty insights regarding incorporation of gender- and sex-related differences in the PharmD curriculum: Phase 2

BACKGROUND

While pharmacists should be aware of gender and sex-related differences in treatment related decisions, this is not a required doctor of pharmacy curricular component. A regional pilot study demonstrated that approximately half of pharmacy practice faculty discussed these differences in their content area. The aim of this study was to evaluate the extent of inclusion of gender and sex-related differences on a national level in doctor of pharmacy curricula and to determine if faculty are comfortable teaching the topic.

METHODS

An electronic message with a link to an online survey was distributed to 7250 faculty members at 139 colleges of pharmacy. The survey remained open for three weeks and potential participants received weekly email reminders. The survey was voluntary, and responses were de-identified.

RESULTS

Overall, 641 faculty participated in the survey (8.8% response rate). Most respondents indicated that they do not teach about gender or sex-related differences (54.9%). Of those faculty reporting teaching gender and/or sex-related differences, 28% indicated that it was addressed in one clinical topic, while some (7.7%) indicated that the content was included in up to five topics. Half of faculty (53.6%) indicated that they believe this topic is somewhat important.

CONCLUSIONS

Results of this study suggest that gender and sex-related differences are not adequately addressed in current pharmacy curricula.

Gender differences in physical activity and sedentary behaviour in adults with intellectual disabilities: A systematic review and meta-analysis

BACKGROUND

Adults with intellectual disabilities are reported to be highly inactive, with research required to understand contributory factors. This systematic review aimed to investigate gender differences in physical activity (PA) and sedentary behaviour (SB) in adults with intellectual disabilities.

METHODS

This systematic review was reported in accordance with PRISMA guidelines. Seven databases were searched up to, and including, January 2018. Screening identified papers that assessed gender-specific PA and/or SB outcomes in adults with intellectual disabilities. Data were synthesized using a narrative synthesis and random effects model meta-analyses.

RESULTS

Twenty-six papers were included; 25 measured PA, and eight assessed SB. Women with intellectual disabilities were least active with a significant overall effect of gender identified. For SB, no consistent gender differences were found.

CONCLUSIONS

Reflecting the general population, men with intellectual disabilities were most active. Intellectual disability research should consider the role of gender to inform future interventions targeting inactivity.

Measuring the data gap: inclusion of sex and gender reporting in diabetes research

Background

Important sex and gender differences have been found in research on diabetes complications and treatment. Reporting on whether and how sex and gender impact research findings is crucial for developing tailored diabetes care strategies. To analyze the extent to which this information is available in current diabetes research, we examined original investigations on diabetes for the integration of sex and gender in study reporting.

Methods

We examined original investigations on diabetes published between January 1 and December 31, 2015, in the top five general medicine journals and top five diabetes-specific journals (by 2015 impact factor). Data were extracted on sex and gender integration across seven article sections: title, abstract, introduction, methods, results, discussion, and limitations.

Results

We identified 155 original investigations on diabetes, including 115 randomized controlled trials (RCTs) and 40 observational studies. Sex and gender were rarely incorporated in article titles, abstracts and introductions. Most methods sections did not describe plans for sex/gender analyses; 47 (30.3%) articles described plans to control for sex/gender in the analysis and 12 (7.7%) described plans to stratify results by sex/gender. While most articles (151, 97.4%) reported the sex/gender of study participants, only 10 (6.5%) of all articles reported all study outcomes separately by sex/gender. Discussion of sex-related issues was incorporated into 21 (13.5%) original investigations; however, just 1 (0.6%) discussed gender-related issues. Comparison by journal type (general medicine vs. diabetes specific) yielded only minor differences from the overall integration results. In contrast, RCTs performed more poorly on multiple sex/gender assessment metrics compared to observational studies.

Conclusions

Sex and gender are poorly integrated in current diabetes original investigations, suggesting that substantial improvements in sex and gender data reporting are needed to inform the evidence to support sex- and gender-specific diabetes care.
