RESUMEN

OBJECTIVES: Influenza infection is an exacerbating factor for asthma, and its prevention is critical in managing asthmatic patients. We investigated the effect of influenza vaccination on asthmatic and non-asthmatic patients hospitalized with laboratory-confirmed influenza in Spain. METHODS: We made a matched case-control study to assess the frequency of hospitalization for influenza in people aged ≥65 years. Hospitalized patients with unplanned hospital admissions were recruited from 20 hospitals representing seven Spanish regions. Cases were defined as those hospitalized due to a laboratory-confirmed influenza infection and controls were matched by age, sex, and hospital. Data were obtained from clinical records, and patients stratified by clinical asthma history. Vaccination status and asthma due to influenza infection were analyzed according to sociodemographic variables and medical risk conditions. Multivariable analysis was made using conditional logistic regression models. RESULTS: 582 hospitalized patients with influenza (15.8% asthmatic) and 1,570 hospitalized patients without influenza (7.9% asthmatic) were included. In the multivariable conditional logistic regression using unvaccinated and non-asthmatic patients as the reference group, vaccination significantly prevented influenza in non-asthmatic patients (aOR = 0.63; 95% CI: 0.45, 0.88) and also showed a trend for a possibly protective effect in asthmatic patients (aOR = 0.79; 95% CI: 0.34, 1.81). CONCLUSION: Our results suggest that influenza vaccination could be a protective factor for asthmatic patients, although the results are inconclusive and further research is required. Practically, given the better clinical evolution of vaccinated asthma cases, and the lack of better evidence, the emphasis on vaccination of this group should continue.

RESUMEN

OBJECTIVE: Children with autism spectrum disorder (ASD) have been found to have alterations in dietary fat intake and fat quality. The fat intakes of the foods consumed by children with and without ASD were compared, and the deficiency and excess of these nutrients were examined. METHODS: In a matched case-control study, 3-day food diaries were completed by 105 children with ASD and 495 typically developing (TD) 6- to 9-year-old children in Valencia (Spain). We used the probabilistic approach and estimated average requirement cut-point to evaluate the risk of inadequate nutrients intakes. These were compared between groups and with Spanish recommendations using linear and logistic regression, respectively. RESULTS: Groups did not differ significantly in age, total dietary intake, Healthy Eating Index, or food variety score. Children with ASD had lower saturated fatty acids (SFAs) and ω-3 polyunsaturated fatty acids (PUFAs) intakes, but their total PUFAs and (PUFAs + monounsaturated fatty acids (MUFAs)/SFAs, PUFAs/SFAs intakes and ω-6/ω-3 ratios were higher than TD children. The total fat and cholesterol intakes of both groups were slightly above Spanish recommendations. Both groups had low ω-6 intakes, very low ω-3 intakes, and high ω-6/ω-3 ratios. CONCLUSION: Further research is required to clarify associations between ASD symptomatology, fat-eating patterns and health status.

RESUMEN

BACKGROUND: Little is known about the healthcare process for patients with prostate cancer, mainly because hospital-based data are not routinely published. The main objective of this study was to determine the clinical characteristics of prostate cancer patients, the, diagnostic process and the factors that might influence intervals from consultation to diagnosis and from diagnosis to treatment. METHODS: We conducted a multicentre, cohort study in seven hospitals in Spain. Patients' characteristics and diagnostic and therapeutic variables were obtained from hospital records and patients' structured interviews from October 2010 to September 2011. We used a multilevel logistic regression model to examine the association between patient care intervals and various variables influencing these intervals (age, BMI, educational level, ECOG, first specialist consultation, tumour stage, PSA, Gleason score, and presence of symptoms) and calculated the odds ratio (OR) and the interquartile range (IQR). To estimate the random inter-hospital variability, we used the median odds ratio (MOR). RESULTS: 470 patients with prostate cancer were included. Mean age was 67.8 (SD: 7.6) years and 75.4% were physically active. Tumour size was classified as T1 in 41.0% and as T2 in 40% of patients, their median Gleason score was 6.0 (IQR:1.0), and 36.1% had low risk cancer according to the D'Amico classification. The median interval between first consultation and diagnosis was 89 days (IQR:123.5) with no statistically significant variability between centres. Presence of symptoms was associated with a significantly longer interval between first consultation and diagnosis than no symptoms (OR:1.93, 95%CI 1.29-2.89). The median time between diagnosis and first treatment (therapeutic interval) was 75.0 days (IQR:78.0) and significant variability between centres was found (MOR:2.16, 95%CI 1.45-4.87). This interval was shorter in patients with a high PSA value (p = 0.012) and a high Gleason score (p = 0.026). CONCLUSIONS: Most incident prostate cancer patients in Spain are diagnosed at an early stage of an adenocarcinoma. The period to complete the diagnostic process is approximately three months whereas the therapeutic intervals vary among centres and are shorter for patients with a worse prognosis. The presence of prostatic symptoms, PSA level, and Gleason score influence all the clinical intervals differently.

RESUMEN

The aim of the present study was to estimate the associations between the prevalence of asthma symptoms in schoolchildren and meteorological variables in west European countries that participated in the International Study of Asthma and Allergies in Children (ISAAC), Phase III 1997-2003. An ecologic study was carried out. The prevalence of asthma was obtained from this study from 48 centers in 14 countries, and meteorological variables from those stations closest to ISAAC centers, together with other socioeconomic and health care variables. Multilevel mixed-effects linear regression models were used. For schoolchildren aged 6-7 years, the prevalence rate of asthma decreased with an increase in mean annual sunshine hours, showed a positive association with rainy weather, and warm temperature, and a negative one with relative humidity and physician density (PD). Current wheeze prevalence was stronger in autumn/winter seasons and decreased with increasing PD. Severe current wheeze decreased with PD. For schoolchildren aged 13-14 years, the prevalence rates of asthma and current wheeze increased with rainy weather, and these rates decreased with increased PD. Current wheeze, as measured by a video questionnaire, was inversely associated with sunny weather, and nurse density. Severe current wheeze prevalence was stronger during autumn/winter seasons, decreased with PD, and indoor chlorinated public swimming pool density, and increased with rainy weather. Meteorological factors, including sunny and rainy weather, and PD may have some effect on the prevalence rates of asthma symptoms in children from west European countries.

RESUMEN

Vitamin D has well-defined classical functions related to metabolism and bone health but also has non-classical effects that may influence pregnancy. Maternal morbidity remains a significant health care concern worldwide, despite efforts to improve maternal health. Nutritional deficiencies of vitamin D during pregnancy are related to adverse pregnancy outcomes, but the evidence base is difficult to navigate. The primary purpose of this review is to map the evidence on the effects of deficiencies of vitamin D on pregnancy outcome and the dosage used in such studies. A systematic search was performed for studies on vitamin D status during pregnancy and maternal outcomes. A total of 50 studies came from PubMed, 15 studies came from Cochrane, and 150 studies came from Embase, for a total of 215 articles. After screening, 34 were identified as candidate studies for inclusion. Finally, 28 articles met the inclusion criteria, which originated from 15 countries. The studies included 14 original research studies and 13 review studies conducted between 2012 and 2021. This review was finally limited to the 14 original studies. This systematic review was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, and the quality and strength of the evidence was evaluated using the Navigation Guide Systematic Review Methodology (SING). We found evidence that supports the idea that supplementary vitamin D for pregnant women is important for reducing the risk of gestational diabetes, hypertension, preeclampsia, early labor, and other complications. The data retrieved from this review are consistent with the hypothesis that adequate vitamin D levels might contribute to a healthy pregnancy.

RESUMEN

The objective of this study was to estimate the relationship between the prevalence of asthma in schoolchildren aged 6-7 years and 13-14 years and the mean annual sunny hours (MASH) in Spain, and to explore predictive models for asthma prevalence. The prevalence of asthma was obtained from the International Study of Asthma and Allergies (ISAAC) Phase III 2002-2003, and climate and socio-economic variables from official sources. Nine centres were studied and a further four centres, two of which are in ISAAC, to test the predictive models. Logistic regression was used to estimate adjusted prevalence rates of asthma for each centre, and multiple regression models to study the effects of MASH and other meteorological and socio-economic variables. The adjusted prevalence rate of asthma decreased 0.6% [95% confidence interval (CI) 0.4-0.8%] for the 6-7 years group and 1.1% (95% CI 0.8-1.3%) for the 13-14 years group with an increase in the MASH of 100 h. Relative humidity was negatively associated with asthma in the older age group, and gross province product per capita (GPP) was positively associated with asthma in the younger age group. The predictive models, which included MASH, gender, relative humidity, and GPP, anticipated prevalence rates of asthma without significant differences between the levels observed and those expected in 9 of the 11 measurements carried out. The results indicate that sunny hours have a protective effect on the prevalence of asthma in schoolchildren.

RESUMEN

OBJECTIVE: In college students, higher risk alcohol consumption (drunkenness and binge drinking-BD) has negative consequences on their development and and probably facilitates risk sexual behaviors. The objective was to study if risky sexual behaviors when consuming alcohol (RSBA) are associated with higher risk consumption. METHODS: Cross-sectional multicenter study with UniHcos Project, 1st year university students from 11 universities in Spain, academic years 2011-2012 to 2017-2018 data. This data were collected by self-administered questionnaire. A uni and bivariate analysis was performed, evaluated the statistical significance of the differences in prevalence with chi-square. Mean and standard deviation were used for quantitative variables and Student's t test statistic was used. RESULTS: 9,862 subjects (72.2% women). 90.3% reported having consumed alcohol and 60.9% had drunk the last year, 49% BD in last month. It was deteded in men, significantly higher consumption in the last month and drunkenness. Last month consumption and drunkenness were significantly higher in men and in <21 years. The RSBA were significantly higher among who were drunk (15.7% unprotected sex, 1.9% sexual abuse and 0.7% taking sexual advantage) and had BD (17.1%, 1.9% and 0.7 %). Women with both risk consumptions had more sexual abuse (2.2%), and men had greater behaviors of taking sexual advantage of someone (drunk: 1.2%; BD: 1.3%). CONCLUSIONS: Alcohol consumption was above similar groups. BD consumption was similar by gender and age. Risk sexual behaviors appear mainly in problematic consumption. Gender differences are not detected in alcohol consumers in unprotected sex but deteded in the rest.


OBJETIVO: En universitarios, el consumo de alcohol de mayor riesgo (borracheras y binge drinking (BD), tiene consecuencias negativas sobre su desarrollo y probablemente facilita conductas sexuales de riesgo. El objetivo de este trabajo fue estudiar si las conductas sexuales de riesgo al consumir alcohol (CSRA) se asocian a los consumos de mayor riesgo. METODOS: Estudio multicéntrico transversal con datos del Proyecto uniHcos, de universitarios de 1er año de 11 universidades españolas, entre los cursos 2011-2012 y 2017-2018. Datos recogidos mediante cuestionario autoadministrado. Se realizó un análisis uni y bivariable, evaluando la significación estadística de las diferencias de prevalencia con chi-cuadrado. Se utilizó media y desviación típica para variables cuantitativas y como estadístico de contraste t de Student. RESULTADOS: 9.862 participantes (72,2% mujeres). El 90,3% consumió alcohol y el 60,9% tuvo borracheras en último año; el 49% tuvo BD en el último mes. El consumo en el último mes y las borracheras fueron mayores en hombres y <21 años. Las CSRA fueron superiores entre los que se emborracharon (15,7% sexo sin protección, 1,9% abuso sexual y 0,7% aprovecharse sexualmente) y consumieron en BD (17,1%, 1,9% y 0,7%). Las mujeres con ambos consumos de riesgo presentaron más abusos sexuales (2,2%), y los hombres fueron quienes más se aprovecharon sexualmente de otros (borracheras:1,2%; BD: 1,3%). CONCLUSIONES: El consumo de alcohol está por encima de grupos similares. El BD tiene un patrón similar por género y edad. Las CSRA se asocian a los consumos de mayor riesgo, no detectándose en este grupo diferencias por género en sexo sin protección, sí en otras CSRA.

RESUMEN

The idea of a united airway disease for asthma and rhinoconjunctivitis is supported by clinical and epidemiological data. However, many asthmatics do not have rhinoconjunctivitis and vice versa. The aim of this study was to investigate if the family history of a specific organ involvement is associated with the implication of the same organ in the allergic child. According to the organ involvement in either or both parents, the family history of 739 children who were skin prick positive to either Dermatophagoides pteronyssinus or D. farinae or both was defined as: asthma and rhinoconjunctivitis positive; asthma and rhinoconjunctivitis negative; asthma negative and rhinoconjunctivitis positive; and asthma positive and rhinoconjunctivitis negative. Asthma and rhinoconjunctivitis in the children were defined according to the International Study of Asthma and Allergies in Childhood questionnaire. Associations between each type of family history and the presence of asthma and/or rhinoconjunctivitis in the children were calculated and adjusted for usual confounders. Adjusted odds ratio of children having asthma, when family history included asthma, was 2.48 (1.38-4.45) when it also included rhinoconjunctivitis; and 2.13 (1.12-4.05) when it did not. However, family history of rhinoconjunctivitis was not associated with asthma in the child. Conversely, the odds ratio of children having rhinoconjunctivitis when family history included rhinoconjunctivitis was 1.84 (1.05-3.21) when it also included asthma; and 1.89 (1.23-2.89) when it did not. Family history of asthma was not associated with rhinoconjunctivitis in the child. In a population of children sensitized to mites, the organ or organs (nose and/or lung) which are implicated in parents tend to be also involved in their children.

RESUMEN

Menstrual problems affect many young women worldwide, conditioning both their academic performance and quality of life. This study sought to analyse the prevalence of menstrual problems and their possible relationship with lifestyle among Spanish university women, as part of a research project (UniHcos Project) involving a cohort of 11 Spanish universities with 7208 university students. A descriptive analysis was performed using the bivariate chi-square test and the Student's t-test together with a binary logistic regression, in which the dependent variable was 'suffering from menstrual problems'. Menstrual problems were identified in 23.8% of the students, representing women who paid more visits to the doctor and to emergency rooms, and who consumed more painkillers and contraceptives. In relation to dietary preferences, menstrual problems were 1.39 (CI 95% 1.22-1.61; p = 0.000) times more likely among women classified as high-risk alcohol users according to the AUDIT questionnaire, and 1.187 (CI 95% 1.029-1.370; p = 0.019) times greater among those who consumed sweets daily, 1.592 (CI 95% 1.113-2.276; p = 0.011) times more frequent among those who eat fish daily, and 1.199 (CI 95% 1.004-1.432; p = 0.045) times greater among those who were dieting. Menstrual problems affect many college students and potentially modifiable lifestyle variables exist which may influence their prevalence. It would be interesting to develop programmes to promote women's health in the university context.

RESUMEN

PURPOSE: Hardly anything is known about the aetiology of thymoma. This paper presents data regarding tobacco smoking and alcohol consumption in relation to thymoma from the first case-control study performed on this rare tumour. METHODS: A European multi-centre case-control study including incident cases aged 35-69 years with thymoma between 1995 and 1997, was conducted in seven countries. A set of controls, used in seven parallel case-control studies by the same research group was used, including population-based controls from five countries and hospital controls with colon cancer from two countries. Altogether 103 cases, accepted by a reference pathologist, 712 colon cancer controls, and 2071 population controls were interviewed. RESULTS: Tobacco smoking was moderately related with thymoma (OR 1.4, 95% CI 0.9-2.2), and a tendency to dose-response was shown (p = 0.04), with an increased risk for heavy smokers defined as ≥41 pack-years (OR 2.1, 95% CI 1.1-3.9). A high consumption of spirits defined as ≥25 g of alcohol per day was associated with an increased risk of thymoma (OR 2.4, 95% CI 1.1-5.4), whereas no association was found with beer or wine. CONCLUSIONS: Tobacco smoking and a high intake of spirits were indicated as risk factors for thymoma.

RESUMEN

OBJECTIVE: To assess the prevalence of illegal drug use in college students on any previous occasion, during the previous year and the previous month, and to analyze the relationship between illegal drug use and family support and other factors. METHODS: A cross-sectional study using data from students participating in the uniHcos project (n = 3767) was conducted. The prevalence and age of onset of consumption of cannabis, non-prescription sedatives, stimulants and depressants was evaluated. Polyconsumption was also assessed. The independent variables were: family support, age, residence, and employment status. To determine the factors related to drug use multivariate logistic regression models stratified by gender were fitted. RESULTS: Differences between men and women in prevalence of illegal drug use except non-prescription sedatives were observed. In both genders, less family support was associated with higher consumption of all drugs, except depressants, and with polyconsumption. To be studying and looking for work was related to cannabis and stimulant use and to polyconsumption among women, but only to cannabis use among men. CONCLUSIONS: These results support the notion that the start of university studies is a particularly relevant stage in the onset of illegal drug use and its prevention, and that consumption may be especially associated with family support.

RESUMEN

OBJECTIVE: We performed a cohort study in seven hospitals in Spain to determine the clinical characteristics of incident patients with bladder cancer, the diagnostic process, and the conditions that might affect health care interval times. RESULTS: 314 patients with bladder cancer were included, 70.3 (Standard Deviation [SD] 11.2) years old and 85.0% male. Clinical stage was T1 in 45.9% of patients. The median interval time between first consultation and diagnosis was of 104.0 days (Inter quartile range [IQR]:112.0; range from 0 to 986), being shorter for those patients who attended a hospital for their first consultation. The median interval time between diagnosis and first treatment was of 0.0 days (IQR: 0.0; range from 0 to 366), being longer when the patient had a pathologic tumor stage ≥ T2a.

RESUMEN

Monitoring of pesticides and veterinary drug residues is required to enforce legislation and guarantee food safety. Liquid chromatography-mass spectrometry (LC-MS) is the prevailing technique for assessing both types of residues because LC offers a versatile and universal separation mechanism suitable for non-gas chromatography (GC) amenable and the majority of GC-amenable compounds. This characteristic becomes more relevant when LC is coupled to MS because the high sensitivity and specificity of the detector allows to apply generic sample preparation procedures, which simultaneously extract a wide variety of residues with different physico-chemical properties. Determination of metabolites and degradation products, non-target suspected screening of an increasing number of residues, and even unknowns identification are also becoming inherent LC-MS advantages thanks to the latest advances. For routine analysis and, in particular, for official surveillance purposes in food control, analytical methods properly validated following strict guidelines are needed. After a brief introduction and an outline of the legislation applicable around the world, aspects such as improvement of specificity of high-throughput methods, resolution and mass accuracy of identification strategies and quantitative accuracy are critically reviewed in this article. In them, extraction, separation and determination are emphasized. The main objective is to offer an assessment of the state of the art and identify research needs and future trends in determining pesticide and veterinary drug residues in food by LC-MS.

RESUMEN

Samples of dead honey bees (Apis mellifera L.) were collected periodically from 4 different locations during citrus and stone fruit trees blooming season to evaluate the potential impact of agrochemicals on honey bee death rate. For the determination of mortality, dead honey bee traps were placed in front of the experimental hives entrance located in areas of intensive agriculture in Valencian Community (Spain). A total of 34 bee samples, obtained along the monitoring period, were analyzed by means of QuEChERS extraction method and screened for 58 pesticides or their degradation products by LC-MS/MS. An average of four pesticides per honey bee sample was detected. Coumaphos, an organophosphate acaricide used against varroosis in the experimental hives, was detected in 94% of the samples. However, this acaricide was unlikely to be responsible for honey bee mortality because its constantly low concentration during all the monitoring period, even before and after acute mortality episodes. The organophosphates chlorpyrifos and dimethoate, as well as the neonicotinoid imidacloprid, were the most frequently detected agrochemicals. Almost 80% of the samples had chlorpyrifos, 68% dimethoate, and 32% imidacloprid. Maximum concentrations for these three compounds were 751, 403, 223 ng/g respectively. Influence of these pesticides on acute honey bee mortality was demonstrated by comparing coincidence between death rate and concentrations of chlorpyrifos, dimethoate and imidacloprid.

RESUMEN

We compared anthropometric values, nutrient intake, the Healthy Eating Index and food variety in children with autism spectrum disorder (ASD), 20 on a gluten-free casein-free (GFCF) diet and 85 on a regular diet in Valencia (Spain) using 3-days food diaries. Those on the GFCF diet had a lower weight, body mass index, and total energy, pantothenic acid, calcium, phosphorus and sodium intake, but a higher intake of fiber, legumes, and vegetables. Further, the GFCF diet group had a better quality of fat intake, but needed supplementation with vitamin D. Randomized controlled trials are required to explore long-term effects of this diet on anthropometric and nutritional status (the focus of our study), but also behavioral symptoms, in children with ASD.

RESUMEN

The objective of this study was to evaluate the relationship between trace and toxic amounts of zinc (Zn) in biological samples (blood and urine) and the smoking habits of hypertensive patients and healthy control subjects in Valladolid (Spain). In order to compare biological samples, the concentrations of these samples were measured using inductively coupled plasma mass spectrometry. The limits of detection for Zn in blood plasma ranged between 4.22 and 17.34 µmol l(-1) and were <0.08 µmol g(-1) creatinine in urine. The results of this study indicate that the highest mean values of serum Zn were found in non-hypertensive nonsmokers (13.39±4.35 µmol l(-1)), whereas the highest urine Zn values were observed in hypertensive nonsmokers (2.78±2.13 µmol l(-1)). Higher Zn serum/urine quotient levels were observed in non-hypertensive and nonsmoking women, whereas lower levels were noted in non-hypertensive and smoking women (P=0.012). This study identified a correlation between Zn serum/urine quotients and cotinine levels (a marker of smoking), a correlation that suggests that smoking lowers the Zn serum/urine quotient, which was lower in hypertensive subjects than in control subjects.

RESUMEN

INTRODUCTION: The risk of having heart related diseases, as well as blood vessels located in the brain and kidneys, increases when the person is hypertensive. This pathology requires additional studies for a better understanding and control of its incidence on health. OBJECTIVE: To evaluate levels of zinc (Zn) in urine and plasma of a representative sample of the population of Valladolid, Spain, in search of alterations of the metabolism of this essential metal caused by hypertension. Method. 1502 serum and urine samples were collected to assess their zinc level in hypertensive and non-hypertensive people varying several characteristics in the population of Valladolid. The concentration of Zn was determined with the technique of mass spectrometry with inductively coupled plasma (ICP-MS). RESULTS: The mean Zn concentration in all biological serum samples was higher and less eliminated in the urine in non-hypertensive patients than hypertensive, untreated and hypertensive patients without treatment without renal damage with 12.83 μmol/L for serum and 2.83 μmol/g creatinine in urine, among the uncontrolled treated hypertensive patients a higher concentration of serum Zn was shown with 12.69 μmol/L and 3.18 μmol/g creatinine in urine than with the group of controlled hypertensive patients. CONCLUSIONS: Hypertension alters the distribution of Zn in the body, causing hypertensive individuals to have a lower serum concentration and eliminate more in the urine

RESUMEN

OBJECTIVE: To assess the psychosocial adjustment in 62 patients surgically treated for cancer of the head and neck. Study design and setting Forty-one patients were grouped as having had radical surgery (total laryngectomy) and 21 as having had functional surgery (horizontal supraglottic laryngectomy or partial vertical surgery). The Psychosocial Adjustment to Illness Scale-Self Report (PAIS-SR) was used for the evaluation. RESULTS: No significant differences were found between groups when global adjustment or domain adjustment was compared. Patients did not consider the permanent stoma and voice loss to be the most important determinant of quality of life. Work and family relationship were the domains with poorest adjustment. CONCLUSION: Social and medical support are important factors in improving patients' self-confidence and satisfaction, playing an important role in recovering useful phonation, psychological adjustment, and global quality of life. SIGNIFICANCE: Information collected in this way may facilitate improved rehabilitation and thus better quality of life.

RESUMEN

Urban groundwater development was traditionally constrained by concerns about its quality. This study was conducted in the regions of La Ribera Alta and Ribera Baja and La Plana de Requena-Utiel of the Valencian Community (Valencia, Spain) where population density, demand for drinking water and agricultural activities are high. Groundwater bodies (GWBs) are regarded as management areas within each territory, and were used to establish protection policies. This study analyzed eleven GWBs. We used two databases with microbiological measurements from 154 wells over a 7-year period (2004-2011), risk factors and groundwater information. Wells were grouped according to frequency of microbiological contamination using E. coli measurements, category <1, or wells with low-frequency microbiological contamination and high-frequency wells or category 1-100, according to World Health Organization (WHO) quality criteria of drinking water. Of all wells, 18.12% showed high-frequency microbiological contamination with a majority distribution in the Ribera Alta region (26.98%, p < 0.001). No significant differences were found between the two risk categories for flow, static level, well depth and distance from population centres. This paper reveals that the vulnerability classes established by the Geological and Mining Institute of Spain (IGME) do not match the microbiological results, and that only eight wells with high-frequency contamination coincide with the high vulnerability areas.

RESUMEN

Vitamin D has important immunomodulatory effects on psoriasis in the Mediterranean region. To measure vitamin D intake in subjects with and without psoriasis, and to find an association with relevant clinical features, a case-control study was performed using cases (n = 50, 50% participation rate) clinically diagnosed with psoriasis and 200 healthy subjects (39.5% participation rate), leaving a final sample of 104 people. A survey was conducted using a food frequency questionnaire and clinical histories. Cases and controls were compared using univariate and multivariate analyses. We observed insufficient intake of cholecalciferol (vitamin D3) or ergocalciferol (vitamin D2) for both cases and controls. Patients with psoriasis were at greater risk of associated pathologies: dyslipidaemia (OR: 3.6, 95% CI: 0.8-15.2); metabolic syndrome (OR: 3.3, 95% CI: 0.2-53.9); hypertension (OR: 1.7, 95% CI: 0.4-7.2). Insufficient vitamin D intake in both psoriasis patients and controls in the Mediterranean population, and cardiovascular comorbility is more frequent in patients with psoriasis.
