RESUMEN
BACKGROUND: Almonds and Brazil nuts are widely consumed allergenic nuts whose presence must be declared according to food labelling regulations. Their detection in food products has been recently achieved by ELISA methods with recombinant antibodies (scFv) isolated against complete Brazil nut and almond protein extracts. The screening of phage-scFv libraries against complete protein extracts confers a series of advantages over the use of purified proteins, as recombinant proteins might alter their native folding. However, using this strategy, the nature of the target detected by phage-displayed antibodies remains unknown, and requires further research to identify whether they are nut allergens or other molecules present in the extract, but not related to their allergenic potential. RESULTS: Electrophoretic, chromatographic, immunological and spectrometric techniques revealed that the Brazil nut (BE95) and almond (PD1F6 and PD2C9) specific phage-scFvs detected conformational epitopes of the Brazil nut and almond 11S globulins, recognised by WHO/IUIS as Ber e 2 and Pru du 6 major allergens. Circular dichroism data indicated that severe heat treatment would entail loss of epitope structure, disabling scFv for target detection. CONCLUSIONS: The presence of important Brazil nut and almond allergens (Ber e 2 and Pru du 6) in foodstuffs can be determined by using phage-display antibodies BE95, PD1F6 and PD2C9 as affinity probes in ELISA. © 2017 Society of Chemical Industry.

Background: The need to study the link between gender, depression, and oral health is becoming increasingly evident. This study therefore aimed to determine the prevalence and evolution over time of depression among women and men with oral health problems and to evaluate the association between depression status, lifestyle-related variables health-related variables and use of dental health services in those people. Methods: We performed a nationwide cross-sectional study on 25,631 adults with oral health problems residing in Spain from the Spanish National Health Survey 2017 and the European Health Survey of Spain 2020, including as the main variable self-reported diagnosis of depression. We analysed independent variables such as lifestyle-related variables, health-related variables, and variables related to dental health services. Sociodemographic characteristics were considered as control variables. Results: The prevalence of depression among adults with oral health problems in Spain was 7.81% (10.14% for women, 5.39% for men), with a notable decrease from 2017 to 2020 in women. Depressed women had a slightly higher percentage of filled or capped teeth, and had more covers (crowns), bridges or other types of prostheses or dentures, while men had more caries. Women also made more frequent, regular dental visits for check-ups and mouth cleaning, whereas men often needed extractions. Unfavourable associated factors in both genders were: perceiving their health as good, average, poor, or very poor, and having 1-2 and ≥ 3 comorbidities. Conversely, not being a current smoker was related to less likelihood of depression. In women only, not engaging in leisure-time physical activity produced more unfavourable associated factors. Conclusion: The prevalence of depression among adults with oral health problems in Spain from 2017 to 2020 was 7.81%, but this figure has been steadily decreasing over time. In addition, the favourable and unfavourable associated factors could help us inform health professionals and authorities in order to prevent depression and enhance the care of this population according to gender.

Many people experience intense fear of COVID-19. The purpose of this study was to provide a comprehensive visual overview of the published literature from 2020 to 2022 assessing fear of COVID-19. From 2020 to 2022, we employed the Scopus database to conduct a bibliometric analysis. We used the VOSviewer program to perform the author co-citation analysis, Mapchart to produce a worldwide map, and Wordart to make a word cloud image. From the 1769 records examined, 1654 (93.50%) were articles, with English being the most common language (96.31%). From 2020 to 2022, annual citations experienced significant growth (R2 = 99.91%; p = 0.0195). The Institut National de la Santé et de la Recherche Médicale (INSERM, France) and China led in terms of publication output (n = 36; n = 255). M. D. Griffiths authored the highest number of articles (n = 21). The most active journal was the International Journal of Environmental Research and Public Health (n = 146), and the most prevalent keyword was "human/s" (11.51%). This bibliometric analysis evaluates the quality of the research on fear of the pandemic and the crisis management of COVID-19, which can provide managers and researchers with crucial insights for future decision making.
RESUMEN
Background: University students are a vulnerable population and faced a significant psychological impact from the COVID-19 pandemic. Therefore, this study aimed to determine the level of fear of COVID-19 among university students and to evaluate the possible relationship between fear of COVID-19 and socio-demographic, health-related determinants, variables related to the COVID-19 and variables related to the psychological impact of the COVID-19 pandemic. Methods: We conducted a cross-sectional study between December 2020 and December 2021 on a sample of 950 university students from two universities in southern Spain. Participants completed a form that collected socio-demographic, health-related and COVID-related variables, a validated questionnaire related to the psychological impact of the COVID-19 pandemic and the fear of COVID Scale (FCV-19S). Descriptive, inferential, and multivariable linear regression analyzes were conducted. Results: The mean FCV-19S score was 14.86 ± 5.16 points. The factors identified as predictors of FCV-19S were being female (p < 0.001), holding religious beliefs (p = 0.04), living in towns with over 10,000 inhabitants (p < 0.01), living with someone vulnerable to COVID-19 (p = 0.02), watching TV to keep informed about COVID-19 (p < 0.01), believing in a low probability of surviving if infected with COVID-19 (p < 0.001), having a higher level of death anxiety (p < 0.001) and suffering from insomnia (p < 0.001). Conclusion: An average fear of COVID-19 score of 14.86 ± 5.16 points has been found among university students in Spain. These findings can aid in identifying specific factors contributing to fear of COVID-19 and in developing coping strategies to alleviate the stress of the pandemic.

Background: Although population screening has improved the early diagnosis of colorectal cancer (CRC), most cases are diagnosed in symptomatic patients. This study aimed to estimate the prevalence and evolution over time of uptake patterns to fecal immunochemical test (FIT) as a screening test for CRC among individuals aged 50-69 in Spain, and to determine the predictive factors for uptake patterns to this type of screening based on sociodemographic, health, and lifestyle characteristics. Methods: A cross-sectional study with 14,163 individuals from the 2017 Spanish National Health Survey and the 2020 European Health Survey was performed, including as the main variable uptake pattern to FIT screening within the last 2 years, with which we analyzed sociodemographic factors, health status and lifestyle habits. Results: 38.01% of participants had undergone FIT in the previous 2 years, and from 2017 to 2020, a significant increase in the uptake rate for CRC was observed (2017: 32.35%, 2020: 43.92%, p < 0.001). The positive predictors to FIT uptake pattern included factors such as being between 57 and 69 years, having a higher educational level or a higher social class, having at least one chronic illness, frequent contact with the primary care physician, alcohol consumption and physical activity, while immigration and smoking habit were negative predictors. Conclusion: In Spain, although the evolution of FIT uptake pattern over time is positive, the prevalence of FIT uptake is still low (38.01%), not reaching the level considered as acceptable in the European guidelines. Moreover, there are disparities in CRC screening uptake among individuals.

Background: Few studies have examined the epidemiology of polypharmacy in non-institutionalized elderly adults with regard to sex differences. This study aimed to identify the prevalence of polypharmacy among people ≥65 years old residing in Spain, analyze trends in that prevalence from 2011/12 to 2020, describe the use of the medicines involved and study the possible relationship between polypharmacy and certain sociodemographic, health-related variables, as well as the use of care services by sex. Methods: A nationwide cross-sectional study with 21,841 non-institutionalized people ≥65 years old from the Spanish National Health Survey (2011/2012 and 2017) and the European Health Survey in Spain (2014 and 2020) was performed. We used descriptive statistics, performing two binary logistic regressions to determine the factors related to polypharmacy. Results: The prevalence of polypharmacy was 23.2% (women: 28.1%, men: 17.2%; p < 0.001). The most commonly consumed medicines were analgesics and tranquillizers, relaxants or sleeping pills in elderly women, compared with antihypertensives, antacids and antiulcer drugs and statins for elderly men. In both sexs, the positive predictors of polypharmacy included average, poor and very poor self-perceived states of health, people with overweight and obesity, being severely/non-severely limited due to a health problem, having ≥ three chronic conditions, visits to the family doctor and hospitalization. Among elderly women, negative predictors were alcohol intake, whereas in elderly men positive predictors were being 75-84 years old, being current smokers and having 1, 2 chronic conditions. Conclusion: Polypharmacy has a prevalence of 23.2%, with women accounting for 28.1% and men 17.2% of the total. Knowledge of positive and negative predictors of polypharmacy have important implications for public health efforts to develop or improve health guidelines and strategies for promoting the proper use of medication, particularly in the elderly population by sex.
RESUMEN
Considering the significance of migraine and the limited amount of research conducted on its association with depression in population-based studies in Spain, this study aimed to determine the prevalence and change of depression from 2017 to 2020 among adults with migraine in Spain and to analyze the sociodemographic and health-related variables linked to depression in migraine sufferers. A cross-sectional study on 5329 adults with migraine from the Spanish National Health Survey 2017 and the European Health Survey in Spain 2020 was performed. Binary logistic regression was used to examine the factors related to depression. A total of 26.32% of people with migraine suffered from depression. No significant changes in that prevalence between 2017 and 2020 were observed. The risk factors associated with depression included being between the ages of 25 and 44 (p = 0.018), being separated or divorced (p = 0.033), being unemployed (p < 0.001), not engaging in recreational physical activity (p = 0.016), perceiving one's health as average, poor, or very poor (p < 0.001), experiencing moderate to severe pain in daily activities (p = 0.011, p = 0.004, p < 0.001, respectively), and having 1-2 or ≥3 chronic conditions (p = 0.003, p < 0.001, respectively). Conversely, being married (p = 0.001) and alcohol consumption (p = 0.007) were identified as protective factors.
RESUMEN
Ensuring equity in cancer screening is recommended by the European Commission. Despite the fact that breast cancer screening is a free population-based program in Spain, there remains considerable variation in the adherence to screening rate among population groups. This study was designed to describe the adherence of breast cancer screening in women in Spain, to evaluate the evolution in the period from 2017 to 2020, and to determine the variables that influence choosing to undergo breast cancer screening. A nationwide cross-sectional study with 7220 females aged 50-69 years from the 2017 Spanish National Health Survey and the 2020 European Health Survey for Spain was performed. We investigated mammography uptake rates, with socio-demographic factors, lifestyle habits, and health-related characteristics as independent variables. Multivariable logistic regression was used to identify the associated factors of mammography adherence. Of the women, 78% had undergone mammography in the previous two years, and there was a significant decrease in the uptake rate for breast cancer screening from 2017 (81.23%) to 2020 (74.68%) (p < 0.001). Educational level, marital status, residential location, nationality, smoking status, alcohol consumption, and leisure-time physical activity were all associated factors of mammography uptake.
RESUMEN
BACKGROUND: Detection and quantification of ochratoxin A (OTA) in dried fig samples purchased in Spain has been carried out using high-performance liquid chromatography with fluorescence detection after extraction with methanol and sodium bicarbonate, and clean-up by using an immunoaffinity column. RESULTS: The detection limit of the method was 0.06 ng g(-1), and the limit of quantification 0.18 ng g(-1) . OTA was detected in 31 (88.6%) out of 35 samples of dried figs analysed, with concentrations that ranged from < 0.1 to 277 ng g(-1). However, only three samples contained OTA concentrations above the tolerable level set by European Commission regulations for dried vine fruits (10 ng g(-1)). CONCLUSION: The results of this survey show the value of monitoring OTA in dried figs especially if they are home grown.

Cervical cancer rates have declined in industrialized nations as a result of cytology screening programs. However, there are still sizeable differences in screening adherence in Spain. This study aimed to identify the prevalence of cervical cancer screening among women in Spain, to analyze trends in that prevalence from 2017 and 2020 and to identify socio-demographic, health, and lifestyle factors related with adherence to this screening test. We conducted a cross-sectional study of 13,619 women aged 25−65 who participated in the 2017 Spanish National Health Survey and the 2020 European Health Survey for Spain. We used logistic regression to examine the relationship between socio-demographic, health and lifestyle factors and cervical cancer adherence. The prevalence of adherence was 73.18%. Additionally, there was a significant decrease in cervical cancer screening uptake from 2017 and 2020 among women aged 25−44 years (2017: 77.80%, 2020: 75.20%, p = 0.02), but an increase in the age group of 45−65 years (2017: 68.93%, 2020: 72.39%, p < 0.01) and in foreigners (2017: 64.29%, 2020: 72.29%, p < 0.01). Screening for cervical cancer is related with age, educational level, social class, insurance status, visits to the family doctor, alcohol consumption and free time physical exercise.
RESUMEN
The psychological, physical and social well-being components may differ for cancer patients living in urban vs. rural zones. This study aimed to examine the common mental disorders (CMDs), functional limitation (FL) and perceived social support (PSS) of rural and urban Spanish cancer patients from 2006 to 2017, to compare sociodemographic variables, health-related determinants and use of healthcare resources and to identify which sociodemographic and health-related factors were related to CMDs, FL and PSS. We performed a cross-sectional study among cancer patients using data from the Spanish National Health Surveys (2006, 2011 and 2017). A total of 698 of the subjects resided in rural areas and 1824 in urban areas. Binary logistic and multiple linear regressions were performed to determine the factors related to CMDs, FL and PSS. Rural residents visited their general practitioners more frequently than the city dwellers (61.03% vs. 56.63%, p = 0.04). A decreased prevalence of CMDs was observed among urban individuals over time (2006: 39.13%, 2011: 38.87%, 2017: 34.30%; p for trend = 0.04). Among rural residents, FL was associated with age, educational level and self-perceived health status, while among city dwellers, PSS was linked to marital status, nationality, having chronic conditions and self-perceived health status.
RESUMEN
Common mental disorders (CMD) are characterized by non-psychotic depressive symptoms, anxiety and somatic complaints, which affect the performance of daily activities. This study aimed to analyze prevalence of diet quality among adults with and without CMD from 2006 to 2017, to study the frequency of food consumption and diet quality according to mental status and age, and to determine which sociodemographic, lifestyle and health-related factors are associated with poor/moderate diet quality, according to mental status. A nationwide cross-sectional study was performed in adults with (n = 12,545) and without CMD (n = 48,079). The data were obtained from three Spanish National Health Surveys (2006, 2011/2012 and 2017). Two logistic regression analyses were used to identify factors associated with diet quality in people with and without CMD. Among those with CMD, the probability of having poor/moderate diet quality was significantly lower for overweight or obese people and those who took part in leisure-time physical activity. Among those without CMD, university graduates were less likely to have a poor/moderate diet quality. Good diet quality was observed more in older adults (≥65 years old) than in emerging (18-24 years old) or young adults (25-44 years old), regardless of mental status.

Certain conditions such as common mental disorders (CMDs), functional limitation (FL) and poor diet quality may affect the lives of individuals who suffer from chronic obstructive pulmonary disease (COPD). This study sought to examine time trends in the prevalence of CMDs, FL and diet quality among male and female COPD patients living in Spain from 2006 to 2017 and to identify which factors were related to CMDs, FL and a poor/improvable diet quality in these patients. We performed a cross-sectional study among COPD patients aged ≥ 40 years old using data from the Spanish National Health Surveys conducted in 2006, 2011 and 2017, identifying a total of 2572 COPD patients. Binary logistic regressions were performed to determine the characteristics related to CMDs, FL and poor/improvable diet quality. Over the years of the study, the prevalence of FL among female COPD patients increased (p for trend <0.001). In addition, CMDs were associated to body mass index (BMI), educational level, physical activity, smoking status, occupation, chronic conditions and alcohol consumption; FL was related to age, living with a partner, educational level, physical activity and chronic conditions; and poor/improvable diet quality was associated to age, smoking status, BMI and physical activity.
RESUMEN
Poor dietary practices are commonly reported in working populations from different economic sectors, resulting in increased absenteeism and a decrease in productivity. The aims of this study were to describe the frequency of food consumption and diet quality in workers aged ≥16 years from 2006 to 2017 in Spain and to evaluate the factors associated with diet quality. A nationwide cross-sectional study was carried out among workers using data from the Spanish National Health Surveys in 2006 (n = 11,068), 2011 (n = 7497) and 2017 (n = 8890). Sociodemographic, occupational, and health-related variables were used as well as diet quality data. A multiple linear regression was performed to determine the characteristics related to overall diet quality. The percentage of workers who consumed vegetables, at most, once or twice per week decreased from 2006 to 2017 (p < 0.001). A lower diet quality score was related to the consumption of tobacco and alcohol and being aged ≥25 years old, while a higher diet quality score was linked to being a woman, having Spanish nationality, receiving optimal perceived social support, being physically active in one's main occupation, doing leisure-time physical activity, and the type of contract.

SCOPE: It is hypothesized that decreased advanced glycation end products (AGEs) levels could affect type 2 diabetes mellitus (T2DM) remission in newly diagnosed patients through the consumption of two healthy diets. METHODS AND RESULTS: Patients from CORDIOPREV study, all with previous cardiovascular events, with T2DM at the beginning of the study are included. Patients are randomized to a Mediterranean or a low-fat diet for five years. No different diabetes remission rates are found among diets. Serum methylglioxal (MG) and carboximethyllysine (CML), levels dietary AGE, as well as gene expression of AGER1 and RAGE are measured. Serum MG decreases only after the consumption of the Mediterranean diet. Moreover, a COX regression analysis shows that each SD decrease in the MG, occurring after the Mediterranean diet, increases the probability of T2DM remission with HR:2.56(1.02-6.25) and p = 0.046 and each SD increase in disposition index at baseline increases the probability of remission with HR:1.94(1.32-2.87) and p = 0.001. CONCLUSIONS: It is demonstrated that the reduction of serum AGEs levels and the modulation of its metabolism, occurring after the consumption of a Mediterranean diet, might be involved in the molecular mechanism underlying the T2DM remission of newly diagnosed patients with coronary heart disease.

BACKGROUND: Workplace violence in healthcare professionals has become a worldwide public health problem and has been the focus of numerous publications; however, currently, no macroscopic overviews of this research based on bibliometric analysis have been carried out. Therefore, the main aim of this study was to analyse the research trends focusing on workplace violence in healthcare personnel over the last 27 years. MATERIALS AND METHODS: A bibliometric study was conducted from 1992 to 2019 in the field of workplace violence in healthcare personnel using the Scopus database. The author co-citation analysis was carried out using VOSviewer software. A worldwide map was created with Mapchart and word cloud image was created using Wordart. Descriptive and inferential statistics were applied. FINDINGS: 1791 records were analysed, 1376 of which (76.83%) were articles, with "Medicine" the most frequent subject category (58.91%). English was the predominant language (93.41%). From 2004 onwards, there was an exponential rise in the number of publications (R2 coefficient = 0.89; p < 0.0001) and the number of annual citations gradually increased from 1995 (R2 coefficient = 0.73; p < 0.0001). The University of Cincinnati (United States) was the institution (and country) with the highest number of publications (n = 30; n = 549), with D. M. Gates leading the ranking of the most productive authors (n = 21). Journal of Nursing Management was the most active journal publishing on the topic (n = 34) and the commonest keyword was "human/s" (16.43%). CONCLUSION: From 1992 to 2019, worldwide research into the published literature on workplace violence in healthcare personnel has grown steadily year by year, both in the number of documents and the number of citations. United States and their institutions and researchers dominates this research output.

The role of diet quality in depression is an emerging research area and it appears that diet quality could be an important modifying factor. The aims of this study were to report the prevalence of diet quality among individuals with and without a self-reported diagnosis of depression aged from 16 to 64 years old in Spain, to analyze the time trends of the frequency of food consumption and diet quality from 2011 to 2017 in individuals with a self-reported diagnosis of depression, and to explore the associations between poor/improvable diet quality and sociodemographic, lifestyle, and health-related factors. A nationwide cross-sectional study was conducted in 42,280 participants with and without a self-reported diagnosis of depression who had participated in the 2011/2012 and 2017 Spanish National Health Surveys and the 2014 European Health Survey in Spain. A logistic regression analysis was performed to identify the variables associated with diet quality. The overall prevalence of diet quality among depressive and non-depressive individuals revealed 65.71% and 70.27% were in need of improvement, respectively. Moreover, having a poor or improvable diet quality is associated with male gender, people aged 16-24 years old and 25-44 years old, separated or divorced, and also in smokers.

Influenza is a significant public health problem and the elderly are at a greater risk of contracting the disease. The vaccination coverage of the elderly is below the Spanish target of 65% for each influenza season. The aims of this study were to report the coverage of influenza vaccination in Spain among the population aged ≥65 years and high-risk groups for suffering chronic diseases, to analyze the time trends from 2006 to 2017 and to identify the factors which affect vaccination coverage. A nationwide cross-sectional study was conducted including 20,753 non-institutionalized individuals aged ≥65 years who had participated in the Spanish National Health Surveys in 2006, 2011/2012, and 2017. Sociodemographic, health-related variables, and influenza vaccination data were used. A logistic regression analysis was performed to determine the variables associated with influenza vaccination. Influenza vaccination coverage was 60%. By chronic condition, older people with high cholesterol levels and cancer had the lowest vaccination coverage (62.41% and 60.73%, respectively). This coverage declined from 2006 to 2017 in both groups. Higher influenza vaccination was associated with males, Spanish nationality, normal social support perceived, polypharmacy, worse perceived health, participation in other preventive measures, and increasing age and the number of chronic diseases.
RESUMEN
Common mental disorders (CMD) represent a serious, growing public health concern, especially in women. The aims of this study were to report the prevalence of CMD among the adult population in Spain, to analyze the time trends from 2006 to 2017 and to explore the associations between CMD and gender, in relation to the perceived environmental and sociodemographic problems and clinical factors. A nationwide cross-sectional study was conducted including 48505 participants aged 16 to 64 years old who had participated in the Spanish National Health Surveys in 2006, 2011/2012 and 2017. A logistic regression analysis was performed to identify the variables associated with CMD by gender. The prevalence of CMD was 20.4% in 2006, 20.8% in 2011/2012 and 16.9% in 2017 (p = 0.36). In women, the probability of having a CMD was higher in widowed or separated/divorced compared with single individuals and as the perception of distressing noise levels from outside the home increased. The probability of CMD was lower as the level of education increased in men. Foreigners and those with limitations due to health problems, chronic conditions and worse perceived health were more likely to suffer from a CMD in both women and men.
RESUMEN
Spanish and immigrant children and adolescents vary widely in their frequency of dental visits and occurrence of dental problems. The aims of this study were to discover the prevalence of dental problems and utilization of dental services in the Spanish and immigrant child population, identify the type of treatment received, and analyze the socioeconomic and demographic variables which are associated with dental problems and non-regular utilization of dental services, based on data from the 2017 National Health Survey in Spain. The sample consisted of 4568 children aged between 3 and 14 years old. Utilization of dental services and dental problems were assessed against socioeconomic and demographic characteristics using logistic regression models. The prevalence of caries in Spanish children was 9.29% compared with 18.58% (p < 0.001) in their immigrant counterparts. The most common reason for dental visits was a check-up (Spanish: 65.05%; immigrants: 54.94%). In both groups, from the age of 7, there was a lower probability of non-regular utilization of dental services, although this increased when the social class was lower. The probability of presenting dental problems was lower in Spanish children living in towns with over 10,000 inhabitants and was higher, in both groups, over the age of 7 and in lower social classes.
