Translating cell therapies for neurodegenerative diseases: Huntington's disease as a model disorder.

There has been substantial progress in the development of regenerative medicine strategies for CNS disorders over the last decade, with progression to early clinical studies for some conditions. However, there are multiple challenges along the translational pipeline, many of which are common across diseases and pertinent to multiple donor cell types. These include defining the point at which the preclinical data are sufficiently compelling to permit progression to the first clinical studies; scaling-up, characterization, quality control and validation of the cell product; design, validation and approval of the surgical device; and operative procedures for safe and effective delivery of cell product to the brain. Furthermore, clinical trials that incorporate principles of efficient design and disease-specific outcomes are urgently needed (particularly for those undertaken in rare diseases, where relatively small cohorts are an additional limiting factor), and all processes must be adaptable in a dynamic regulatory environment. Here we set out the challenges associated with the clinical translation of cell therapy, using Huntington's disease as a specific example, and suggest potential strategies to address these challenges. Huntington's disease presents a clear unmet need, but, importantly, it is an autosomal dominant condition with a readily available gene test, full genetic penetrance and a wide range of associated animal models, which together mean that it is a powerful condition in which to develop principles and test experimental therapeutics. We propose that solving these challenges in Huntington's disease would provide a road map for many other neurological conditions. This white paper represents a consensus opinion emerging from a series of meetings of the international translational platforms Stem Cells for Huntington's Disease and the European Huntington's Disease Network Advanced Therapies Working Group, established to identify the challenges of cell therapy, share experience, develop guidance and highlight future directions, with the aim to expedite progress towards therapies for clinical benefit in Huntington's disease.

Gender inequalities in depression/anxiety and the consumption of psychotropic drugs: Are we medicalising women's mental health?

Aims: Clinical studies show that women are more likely to be diagnosed with depression and anxiety, and to consume prescribed psychotropic drugs. Applying an intersectional perspective that considers age, education and social class, the present study assesses gender inequalities in the diagnosis of depression/anxiety and in psychotropic consumption. Methods: We analysed data from the 2018 Basque Country Health Survey (Spain; n=8014). Prevalence rates of poor mental health, diagnosis of depression/anxiety and psychotropic consumption were calculated for each sex by age and socio-economic status. Poisson regression models were calculated to estimate PRs of these variables in women, adjusted for age, mental health status and health-care visits, and for diagnosis of depression/anxiety in the case of psychotropic drug consumption. Results: Women were 2.48 times more likely than men to be diagnosed with depression or anxiety, and this difference remained significant after adjustments (prevalence ratio (PR)=1.86; 95% confidence interval (CI) 1.40-2.47). Women also took significantly more prescribed psychotropic drugs, even controlling for their poorer mental health, their higher prevalence of diagnosis and their more frequent health-care visits (PR=1.52; 95% CI 1.28-1.82). No gender inequalities were observed in those younger than 45 or with the highest level of education. Conclusions: Gender inequalities in the diagnosis and prescription of psychotropic drugs exist, and these cannot be explained by differences in mental-health status or health-care visit frequency. It seems, then, that medicalisation of mental health is occurring among women. Further evidence about the mechanisms that underlie the results is crucial to design truly gender-sensitive health policies that reduce medicalisation of women's mental health.

The impact of precarious jobs on mental health: a gender-sensitive literature review.

PURPOSE: The aim of this study is to analyse the extent to which research and knowledge production on a key occupational health issue-the impact of precarious employment on health-incorporates, and is sensitive to, a gender perspective. METHODS: A systematic literature review was carried out to identify studies that analysed the relationship between precarious employment and mental health in the period January 2010-May 2018 through. A minimum of two independent reviewers assessed each article for quality and eligibility. A checklist was used to determine whether the articles included in the review incorporated a gender perspective. RESULTS: The search retrieved 1522 papers, of which 54 (corresponding to 53 studies) met the inclusion criteria. Of these 54 papers, 22 (40.7%) stratified the analyses by sex. Only 5.4% of the total of articles both stratified by sex and considered variables of household composition and marital status, while only 33.3% incorporated an intersectional perspective. None considered the distribution of domestic work and only a quarter (25.9%) approached the study and interpreted the results in terms of gender. CONCLUSION: Too few studies researching paid work and health include a gender perspective. This omission necessarily implies a biased interpretation of the reality of precarious employment and its impact on health.

Inequalities in participation in colorectal cancer screening programmes: a systematic review.

BACKGROUND: Colorectal cancer (CRC) is a major public health problem due to its incidence and mortality. Screening programmes help decrease its impact on the population through early detection. However, the uneven distribution of social determinants of health can cause inequalities. The aim of this study is to identify the social inequalities in the participation in CRC screening programmes. METHODS: A systematic review of the literature was carried out, searching in both health and social databases for papers published since 2000 in English, Spanish, Portuguese and French. The search strategies combined terms regarding screening, CRC, participation and social inequalities. Included papers were quantitative or qualitative primary studies analyzing gender and socioeconomic inequalities in the participation in CRC screening programmes implemented by public and private health-care providers and addressing 45- to 75-year-old population. RESULTS: A total of 96 studies, described in 102 articles, were included. Most were quantitative observational studies and analyzed population-based screening programmes. They were carried out mainly in the UK (n=29) and the USA (n=18). Participation in screening programmes varied from 1.1% to 82.8% using several methods. A total of 87 studies assessed participation by sex and one focussed on men, but only two provided an analysis from a gender perspective. Although men are at a higher risk of developing CRC, they generally were less likely to participate in screening programmes. Screening attendance was higher among the least deprived areas. CONCLUSIONS: Gender and socioeconomic inequalities in CRC screening participation should be addressed through the design of tailored interventions with a multidimensional focus.

Inequalities in Health Services Usage in a National Health System Scheme: The Case of a Southern Social European Region.

BACKGROUND: Health services can reduce inequalities caused by other determinants of health or increase them due to the effect of the inverse care law-the principle that the availability of good quality care tends to vary inversely with the need for it in the population served. OBJECTIVE: The purpose of the research was to describe inequalities in the use of nursing services, medical services in primary care, specialist care, and services not fully covered by the Basque public health system in Spain. METHODS: A cross-sectional study of adults aged at least 25 years who completed the 2013 Basque Health Survey (N = 10,454) was conducted. Age-standardized prevalence and prevalence ratios for use of services that are covered and noncovered in the health system were computed. The association of health services usage with socioeconomic variables was estimated using a Poisson regression model with robust variance. The relative index of inequality (RII) was used to measure the magnitude of socioeconomic status inequalities in health service use. All analyses were carried out separately for men and women. RESULTS: Individuals with lower socioeconomic status were more likely to use primary care (RII = 0.87, 95% CI [0.79, 0.97]) and less likely to use specialist services (RII = 0.82, 95% CI [0.75, 0.89]). Across noncovered health services, inequalities between the highest and lowest social groups were significant in all cases and especially marked in men's use of physiotherapists (RII = 0.46, 95% CI [0.35, 0.61]) and podiatrists (RII = 0.24, 95%CI [0.15, 0.38]). DISCUSSION: There are significant inequalities in primary and specialist health service use based on individual socioeconomic status, particularly for services that are not provided free of charge within the existing health system. This suggests that health service systems that are not explicitly designed to provide universal access may actually amplify preexisting social and health inequalities within their target populations.

The role of birthplace and educational attainment on induced abortion inequalities.

BACKGROUND: Induced abortion (IA) has shown social inequality related to birthplace and education with higher rates of IAs in immigrant and in less educated women relative to their native and highly educated counterparts. This study examined the independent and joint effects of birthplace and education on IA, repeated and IA performed during the 2nd trimester of pregnancy among women residing in the Basque Country, Spain. METHODS: We conducted a cross-sectional population-based study of IA among women aged 25-49 years residing in the Basque Country, Spain, between 2011 and 2013. Log-binomial regression was used to quantify the independent and joint effects of birthplace and education attainment on all outcomes. RESULTS: Immigrant women exhibited higher probability of having an IAs (PR: 5.31), a repeated (PR: 7.23) or a 2nd trimester IAs (PR: 4.07) than women born in Spain. We observed higher probabilities for all outcomes among women with a primary or less education relative to those with a graduate education (All IAs PR: 2.51; repeated PR: 6.00; 2nd trimester PR: 3.08). However, no significant heterogeneity was observed for the effect of education on the association of birthplace with IAs, repeated or 2nd trimester IAs. CONCLUSIONS: Birthplace and education are key factors to explain not only an IA decision but also having a repeated or a 2nd trimester IA. However, the effects of birthplace and education may be independent from each other on these outcomes. A better understanding of these factors on IAs is needed when designing programs for sexual and reproductive health aimed to reduce inequalities among women.

The impact of the Great Recession on mental health and its inequalities: the case of a Southern European region, 1997-2013.

BACKGROUND: Numerous studies have shown that macroeconomic changes have a great influence on health, prompting different concerns in recent literature about the effects of the current recession. The objective of the study was to assess the changes in the mental health of the working-age population in the Basque Country (Spain) and its social inequalities following the onset of the 2008 recession, with special focus on the role of unemployment. METHODS: Repeated cross-sectional study on the population aged 16-64, using four Basque Health Surveys (1997-2013). Age-adjusted prevalences of poor mental health and incremental prevalence ratios (working status and social class adjusted) between years were calculated. Absolute/relative measures of social inequalities were also calculated. RESULTS: From 2008, there was a clear deterioration in the mental health, especially among men. Neither changes in employment status nor social class accounted for these changes. In men, the deterioration affected all working status categories, except the retired but significant changes occurred only among the employed. In women, poor mental health significantly increased among the unemployed. Students were also especially affected. Relative inequalities increased only in men. CONCLUSIONS: The Great Recession is being accompanied by adverse effects on mental health, which cannot be fully explained by the increase of unemployment. Public health professionals should closely monitor the medium and long-term effects of the crisis as these may emerge only many years after the onset of recessions.

Why is There so Much Controversy Regarding the Population Health Impact of the Great Recession? Reflections on Three Case Studies.

In the aftermath of the Great Recession, public health scholars have grown increasingly interested in studying the health consequences of macroeconomic change. Reflecting existing debates on the nature of this relationship, research on the effects of the recent economic crisis has sparked considerable controversy. On the one hand there is evidence to support the notion that macroeconomic downturns are associated with positive health outcomes. On the other hand, a growing number of studies warn that the current economic crisis can be expected to pose serious problems for the public's health. This article contributes to this debate through a review of recent evidence from three case studies: Iceland, Spain, and Greece. It shows that the economic crisis has negatively impacted some population health indicators (e.g., mental health) in all three countries, but especially in Greece. Available evidence defies deterministic conclusions, including increasingly "conventional" claims about economic downturns improving life expectancy and reducing mortality. While our results echo previous research in finding that the relationship between economic crises and population health is complex, they also indicate that this complexity is not arbitrary. On the contrary, changing social and political contexts provide meaningful, if partial, explanations for the perplexing nature of recent empirical findings.

Changes in social inequalities in disability-free life expectancy in Southern Europe: the case of the Basque Country.

BACKGROUND: Health expectancy is a useful tool to monitor health inequalities. The evidence about the recent changes in social inequalities in healthy expectancy is relatively scarce and inconclusive, and most studies have focused on Anglo-Saxon and central or northern European countries. The objective of this study was to analyse the changes in socioeconomic inequalities in disability-free life expectancy in a Southern European population, the Basque Country, during the first decade of the 21st century. METHODS: This was an ecological cross-sectional study of temporal trends on the Basque population in 1999-2003 and 2004-2008. All-cause mortality rate, life expectancy, prevalence of disability and disability free-life expectancy were calculated for each period according to the deprivation level of the area of residence. The slope index of inequality and the relative index of inequality were calculated to summarize and compare the inequalities in the two periods. RESULTS: Disability free-life expectancy decreased as area deprivation increased both in men and in women. The difference between the most extreme groups in 2004-2008 was 6.7 years in men and 3.7 in women. Between 1999-2003 and 2004-2008, socioeconomic inequalities in life expectancy decreased, and inequalities in disability-free expectancy increased in men and decreased in women. CONCLUSIONS: This study found important socioeconomic inequalities in health expectancy in the Basque Country. These inequalities increased in men and decreased in women in the first decade of the 21st century, during which the Basque Country saw considerable economic growth.

Effect of Preoperative Administration of Dexamethasone vs. Methylprednisolone in Surgical Extraction of Impacted Lower Third Molars: Randomized Controlled Clinical Trial.

Background/Objectives: Glucocorticoids are drugs that are increasingly used in oral surgery to reduce trismus, inflammation, and postoperative pain, three frequent complications after the surgical extraction of impacted lower third molars. The aim of this study was to compare the effect of 8 mg dexamethasone versus 40 mg methylprednisolone in the prevention of postoperative complications after third molar surgery. Methods: A randomized double-blind clinical trial was conducted following CONSORT guidelines. In detail, 84 patients were included in the study, who randomly received a single preoperative submucosal dose of dexamethasone (8 mg) or methylprednisolone (40 mg). The variables analyzed, as primary outcomes, were trismus, inflammation, and postoperative pain. The measurements were performed at baseline (0 h), 3 h, 7 h, 24 h, 48 h, and 7 th day using a Visual Analog Scale (VAS), Verbal Rating Scale (VRS), and the Gabka-Matsumara method. Results: Dexamethasone reduced trismus, inflammation, and postoperative pain significantly better than methylprednisolone. Conclusions: Preoperative submucosal administration of 8 mg dexamethasone is effective and safe in reducing the severity of postoperative complications following surgical extraction of impacted lower third molars.

Two decades of inequalities in smoking prevalence, initiation and cessation in a southern European region: 1986-2007.

BACKGROUND: The smoking epidemic is still progressing in southern Europe. We aimed to analyse the magnitude and trend of social inequalities in smoking prevalence, initiation and cessation in the Basque Country, a southern European region, from 1986 to 2007, determining the patterns by sex and age. METHODS: This was a cross-sectional time trend study on the population aged >24 years using the Basque Country Health Surveys of 1986, 1992, 1997, 2002 and 2007. Age-adjusted prevalence of current and ever smoking and cessation were calculated, as were relative index of inequality and population-attributable risk by occupational social class and educational level. Relative risk of starting smoking was estimated using Cox proportional hazard regression models. Calculations were performed separately by sex and for two age groups (25-44 years and >44 years). RESULTS: Men and young women in the Basque Country have evolved towards the last stage of the epidemic, with an increasing concentration of smoking in disadvantaged groups, by educational level, especially among the youngest population. In older women, smoking continues rising, especially among higher socio-economic groups, though differences between groups are diminishing. The role of initiation and cessation inequalities as determinants of smoking inequalities differed considerably by age and sex. CONCLUSION: Inequalities in smoking prevalence widened from 1986 to 2007 in the Basque Country, especially among the youngest population. The changing pattern of these inequalities and the different roles of initiation and cessation dynamics need to be taken into account to improve the results of tobacco control policies and their effect on smoking inequalities.

Gender Inequalities in Publications about COVID-19 in Spain: Authorship and Sex-Disaggregated Data.

Gender inequalities in biomedical literature have been widely reported in authorship as well as the scarcity of results that are stratified by sex in the studies. We conducted a bibliometric review of articles on COVID-19 published in the main Spanish medical journals between April 2020 and May 2021. The purpose of this study was to analyse differences in authorship order and composition by sex and their evolution over time, as well as the frequency of sex-disaggregated empirical results and its relationship with the author sex in articles on COVID-19 in the main Spanish biomedical journals. We identified 914 articles and 4921 authors, 57.5% men and 42.5% women. Women accounted for 36.7% of first authors and for 33.7% of last authors. Monthly variation in authorship over the course of the pandemic indicates that women were always less likely to publish as first authors. Only 1.0% of the articles broke down empirical results by sex. Disaggregation of results by sex was significantly more frequent when women were first authors and when women were the majority in the authorship. It is important to make gender inequalities visible in scientific dissemination and to promote gender-sensitive research, which can help to reduce gender bias in clinical studies as well as to design public policies for post-pandemic recovery that are more gender-equitable.

[Socioeconomic inequalities and COVID-19 in Spain. SESPAS Report 2022]. / Desigualdades socioeconómicas y COVID-19 en España. Informe SESPAS 2022.

The COVID-19 pandemic has shown its syndemic nature where the contagion by coronavirus joins the high prevalence of chronic diseases in a context of great social inequality and a clear gradient of those pathologies. The objectives of this article are: 1) to show a conceptual framework of the determinants of social inequality in the COVID-19; 2) to review the available literature on socioeconomic inequalities in various aspects related to COVID-19 in Spain; and 3) propose recommendations to monitor, intervene with policies and communication guides to reduce social inequalities in COVID-19, showing examples developed in Spain. The conceptual framework includes structural and intermediate determinants reflecting the different axes of inequality that characterize the syndemic nature of COVID-19. The literature review published up to July 2021 in Spain describes a socioeconomic gradient of COVID-19, not always consistent among studies, as well as an uneven impact of many measures to control the pandemic. Finally, the proposals for reducing social inequalities in COVID-19 include: 1) to guarantee information systems and research with an equity perspective; 2) to reduce inequalities in COVID-19 through its intermediate, and economic and political determinants; and 3) to design communication models and understanding frameworks that break with hegemonies that hide the relevance of social inequality in the pandemic. Given the syndemic nature of COVID-19 and accumulated knowledge, surveillance systems, interventions and communication must include a clear perspective of health equity.

[How do the different dimensions of precarious employment affect mental health?] / ¿Cómo afectan las distintas dimensiones de la precariedad laboral a la salud mental?

OBJECTIVE: To analyse the relationship between precarious employment, measured by dimensions and as a multidimensional index, on the mental health of salaried men and women in the Basque Country (Spain). METHOD: A subsample (n=3345) of the 2018 Basque Autonomous Community Health Survey was used to calculate the standardised prevalence of poor mental health according to the degree of precarious employment, measured as a composite scale and by each of its dimensions, and to perform robust Poisson regression models to analyse the association between precarious employment, also composite and by dimensions, and the mental health of the salaried population. RESULTS: Precarious employment is significantly associated with poor mental health among men (prevalence ratio [PR]: 3.51; 95% confidence interval [95%CI]: 2.05-6.01) and women (PR: 3.42; 95%CI: 2.35-4.97). Additionally, some of its constituent dimensions, such as wage level among both sexes (PR: 2.58, 95%CI: 1.65-4.03, and PR: 2.29, 95%CI: 1.58-3.32) or vulnerability among women (PR: 2.55; 95%CI: 1.80-3.61), also appear to be significantly and independently related to poorer mental health status. CONCLUSIONS: It is necessary to approach precarious employment from a multidimensional perspective, and to know the relative importance of each of its dimensions, both for research into its effects on health and for policy interventions directed at combating this phenomenon.

[Monitoring COVID-19 in Spain: is a gender analysis possible?] / Monitorización de la COVID-19 en España: ¿es posible un análisis con perspectiva de género?

OBJECTIVE: To analyse the sex disaggregation and availability of gender indicators in the reports of the National Epidemiological Surveillance Network (RENAVE) and the National Study of Sero-Epidemiology (ENE-COVID-19). METHOD: Peer review of indicators available in 72 RENAVE reports and 4 rounds of the ENE-COVID-19 study to calculate the percentage of those disaggregated by sex and their variation over time. RESULTS: In March 2021, 52.4% of RENAVE indicators were disaggregated by sex. From July 2020, 54% of disaggregated indicators ceased to be published and 23% lost their disaggregation. In the ENE-COVID-19 study, the 1st round 88,23% of the indicators are disaggregated and the 4th round 94,74%. The 2nd and 3rd round do not disaggregated by sex. CONCLUSIONS: The RENAVE reports do not allow for a gender-sensitive analysis while the ENE-COVID-19 study provides the most information on social determinants.

Socioeconomic Inequalities in Small-for-Gestational-Age Births Before and During the Economic Crisis: An Ecologic Study of Trends in 13 Spanish Cities.

Economic recessions can increase socioeconomic inequalities in health. The objective of this study was to analyze socioeconomic inequalities in small-for-gestational-age (SGA) births before and during the Spanish economic crisis. We conducted an ecological study of trends based on 2 periods before the crisis (1999-2003 and 2004-2008) and another during the crisis (2009-2013). The study population was Spanish women resident in 13 cities who had given birth during 1999-2013. The prevalence of SGA was calculated for each census tract. A hierarchical Bayesian model was used to obtain the prevalence ratio (PR) and 95% credible intervals (CI). We analyzed the association between SGA and socioeconomic deprivation in each period for each city and for 3 age groups. The PR was above 1 and statistically significant for all 3 time periods in most of the 13 cities. The differences in PR between periods were only statistically significant for Madrid (PR = 1.56, 95% CI 1.48-1.65 for 1999-2003; PR = 1.28, 95% CI 1.19-1.38 for 2004-2008) and Barcelona (PR = 0.99, 95% CI 0.87-1.12 for 2004-2008; PR = 1.20, 95% CI 1.05-1.36 for 2009-2013). Socioeconomic inequalities in SGA births in small areas (census tracts) of most Spanish cities studied remained stable before and during the economic crisis.

Social Inequalities in Health Determinants in Spanish Children during the COVID-19 Lockdown.

The COVID-19 lockdown was imposed in a context of notable inequalities in the distribution of the social determinants of health. It is possible that the housing conditions in which children and their families experienced the confinement, and the adoption of healthy behaviors, may have followed unequal patterns. The aim was to describe social inequalities in housing conditions and in health-related behaviors among children during the lockdown in Spain. This cross-sectional study was based on data from an online survey collecting information on the child population (3-12 years) living in Spain (n = 10,765). The outcome variables used were several housing conditions and health-related behaviors. The socioeconomic variables used were financial difficulties and parents' educational level. Crude prevalence and prevalence ratios estimated using Poisson models were calculated. During lockdown, children from families with low educational levels and financial difficulties not only tended to live in poor housing conditions, but were also exposed to negative health determinants such as noise and tobacco smoke; they took less physical exercise, had a poorer diet, spent more time in front of screens and had less social contact. A notable social gradient was found in most of the variables analyzed. The results point to the need to incorporate the perspective of equity in the adoption of policies in order to avoid the increase of pre-existing social inequalities in the context of a pandemic.

[COVID-19 and gender: certainties and uncertainties in monitoring the pandemic.] / COVID-19 y género: certezas e incertidumbres en la monitori-zación de la pandemia.

OBJECTIVE: Highlighting gender inequalities during the pandemic and its relationship with other axes of social inequality will be decisive for its adequate monitoring. The aim of this study was to assess the differences between men and women in the main measures of infection and mortality by COVID-19, considering its temporal evolution, raising awareness about the weaknesses and contradictions between sources of information. METHODS: Cross-sectional analysis based on the microdata on COVID cases notified by the National Epidemiological Surveillance Network (RENAVE), the Death Statistics of the National Statistical Institute (INE) and the estimates of excess mortality from the INE and the Daily Mortality Monitoring System (MoMo) microdata. Standardized rates, prevalences and and ratios by sex were calculated for each indicator. The percentage of excess mortality without COVID-19 diagnosis in each sex was calculated. Male/female ratios for symptoms and risk factors of COVID-19 were also calculated. RESULTS: The rate of infection by COVID-19 was higher in women in the three waves of the pandemic, reaching 65% of infections during April and May 2020. Complications were between 1.5 and 2.5 times higher in men, especially in ICU admissions, which were 2.5 times more frequent than in women. Although mortality rates and excess mortality were also higher in men (around 1.8 times), the percentage of excess mortality without COVID-19 diagnosis was higher in women (44% in men vs. 52% in women the first wave). With regard to the symptoms of COVID-19, fever, cough, and dyspnoea were more frequent in men (20%, 10% and 19% more, respectively) compared to sore throat, vomiting or diarrhea that were more prevalent in women (90%, 40% and 10% more, respectively). CONCLUSIONS: The analysis disaggregated by sex has made it possible to identify differences between men and women in the diagnosis, presentation and severity of the COVID-19 that can help a better clinical and epidemiological approach to the disease. However, official sources present important gaps when presenting information disaggregated by sex. It is therefore necessary to advance in the inclusion of a gender perspective in the statistics on COVID-19, starting with a necessary but not sufficient condition such as the disaggregation by sex of the data.

OBJETIVO: Visibilizar las desigualdades de género durante la pandemia y su relación con otros ejes de desigualdad social resultará decisivo para su adecuada monitorización. El objetivo de este estudio fue analizar las diferencias entre hombres y mujeres en las principales medidas de contagio, complicaciones y mortalidad por la COVID-19 teniendo en cuenta la evolución temporal de las mismas a lo largo de la pandemia en el estado español, visibilizando las aportaciones y carencias entre fuentes de información. METODOS: Análisis transversal en base a los casos COVID notificados por la Red Nacional de Vigilancia Epidemiológica (RENAVE); las estimaciones de mortalidad del Instituto Nacional de Estadística (INE) y las estimaciones de exceso de mortalidad del INE y los microdatos del Sistema de Monitorización de la Mortalidad diaria (MoMo). Se calcularon tasas, prevalencias y ratios por sexo de cada indicador. Se calculó el porcentaje de exceso de mortalidad sin diagnóstico COVID-19 en cada sexo. Se calcularon, así mismo, las ratios hombres/mujeres para los síntomas y factores de riesgo de la COVID-19 recogidos. RESULTADOS: La tasa de infección por la COVID-19 fue superior en mujeres en las tres olas de la pandemia, llegando a constituir un 65% de las infecciones durante abril y mayo de 2020. Las complicaciones por coronavirus fueron entre 1,5 y 2,5 veces mayores en hombres de manera constante especialmente en las admisiones en UCI que llegaron a ser 2,5 veces más frecuentes que en mujeres. Si bien las tasas de mortalidad y el exceso de mortalidad fueron también superiores en hombres (en torno a 1,8 veces), el porcentaje de exceso de mortalidad sin diagnóstico COVID-19 fue superior en mujeres (44% en hombres frente a 52% en mujeres en la primera ola). Con respecto a los síntomas de la COVID-19, la fiebre, la tos y la disnea fueron más frecuentes en hombres (un 20%, 10% y 19% más, respectivamente) frente al dolor de garganta, vómitos o diarrea que se presentó más en mujeres (90%, 40% y 10% más, respectivamente). CONCLUSIONES: El análisis desagregado por sexo ha permitido identificar diferencias entre hombres y mujeres en el diagnóstico, presentación y gravedad de la COVID-19 que ayudarán a un mejor abordaje clínico y epidemiológico de la enfermedad. Sin embargo, las fuentes oficiales presentan importantes lagunas a la hora de presentar la información desagregada por sexo. Es por ello necesario avanzar en la inclusión de la perspectiva de género en la estadística sobre el COVID-19, empezando por una condición necesaria, pero no suficiente, como la desagregación por sexo de los datos.

[Online surveys and the false illusion of the large n. On a survey on euthanasia among medical practitioners]. / Las encuestas online y la falsa ilusión de la n grande. A propósito de una encuesta sobre la eutanasia en profesionales médicos.

The use of studies based on online surveys has expanded significantly. Despite having particularly small response rates, they allow a large sample size to be easily obtained. However, this strategy may entail a selection bias that significantly compromises the results. The results of two surveys on the regulation of euthanasia and assisted suicide are compared. One is an online survey with a self-selected sample and the other a survey with random sampling, conducted in 2018 among the members of the Medical Association of Bizkaia. The response rates were 10.4% (online survey) and 87.8% (random survey). No differences were found in sociodemographic characteristics, although there were differences in the opinion variables, so that the percentage of people who opposed euthanasia regulation was overestimated. The results of this study show that this sampling strategy generates biases in the results, some of which are difficult both to detect and to repair.

Diagnosis and Treatment of Depression in Spain: Are There Gender Inequalities?

It is well known that women are more likely than men to be diagnosed with depression and to consume antidepressants. The factors related to the medicalisation of depression and their social distribution remain unclear. The aim of this study was to analyse gender inequalities in the medicalisation of depression from an intersectional perspective. This was a cross-sectional study based on data from the European Health Survey relating to Spain. Gender inequalities were calculated using prevalence ratios of women compared to men with a diagnosis of depression and antidepressant use, adjusted for age, depressive symptoms, primary care visits and diagnosis of depression in the case of antidepressant use. After adjustments, the diagnosis of depression and the use of antidepressants were more prevalent in women, especially of lower socioeconomic levels. Gender inequalities in the diagnosis of depression also increased with decreasing level of education. Regarding the use of antidepressants, gender inequalities were not significant in university graduates and people of higher social. The gender inequalities found in the diagnosis and treatment of depression cannot be completely attributed to a higher level of depressive symptoms in women or their greater frequency of visits to primary care. Inequalities are greater in more vulnerable social groups.
