Severity of COVID-19 cases in the months of predominance of the Alpha and Delta variants.

New SARS-CoV-2 may pose problems in controlling the COVID-19 pandemic for public health. We aimed to assess and compare the symptoms and severity of cases due to the Alpha and Delta variant dominance periods, taking into account the effect of COVID-19 vaccination. A prospective epidemiological study of SARS-CoV-2 in Lleida was made to determine differences between Alpha and Delta variants periods. We assessed symptoms, specific comorbidities, sociodemographic information and vaccination status. Bivariate and logistic regression analyses were used to estimate the adjusted odds ratio (aOR) and 95% confidence intervals (CI) to investigate the relationship between symptoms and severity and the variants. Alpha variant period compared to the Delta showed an increased risk of ICU admission (aOR 2.0; 95% CI 1.2-2.3) and death (aOR 2.6; 95% CI 1.8-3.9) and cases were associated with people aged > 85 years (aOR 2.1; 95% CI 1.7-2.6) and partially vaccinated (aOR 5.6; 95% CI 3.2-9.9) and unvaccinated people (aOR 27.8; 95% CI 19.7-40.5). Fever, cough and vomiting were significantly associated with the Alpha variant compared to the Delta (aOR 1.6 (95% CI 1.5-1.7), 2.0 (95% CI 1.9-2.2) and 2.5 (95% CI 2.2-2.9, respectively). Our results show that the severity and profile of clinical symptoms varied according to the variant. The risk of ICU admission and death was higher in the Alpha period compared to the Delta as it affected the elderly and cases were less vaccinated.

Irrigation implementation promotes increases in salinity and nitrate concentration in the lower reaches of the Cidacos River (Navarre, Spain).

The shift from rainfed to irrigated agriculture is associated with a change in the fertilization rates due to increases in expected production and the fact of growing more N demanding crops. In addition, the circulation of irrigation return flows (IRF) mobilizes soluble salts stored in soils or geological materials. As a consequence, it implies severe modifications in the dynamics and total amount of soluble salts and nitrogen exported, especially in semi-arid watersheds. In this study, long-term data collected by the regional authorities was used to assess the effects of irrigation implementation on salinity (using electrical conductivity, EC, as a proxy) and nitrate concentration (NO3-) after the transformation of ca. 77 km2 from rainfed to irrigated agriculture in the Cidacos River (CR) watershed. The results indicate that water quality in the lower reaches of the CR was significantly modified after the diffuse incorporation of IRF. In contrast, neither EC nor NO3- were different in those monitoring stations whose contributing watersheds did not include transformed area. In addition, the temporal dynamics in the analysed variables shifted from a rainfed land signal typical in the region to an irrigated land signal, and the hydrochemical type of the CR shifted from mixed-to-Na+-mixed-to-HCO3- to mostly Na+-mixed type, typical of waters affected by IRF in the region. Groundwater EC and NO3- also increased in those wells located within the irrigated area. Although there are great uncertainties in the actual amount of salt and N reaching the CR via IRF, the expected contribution of waste water spilled into the CR is minor in comparison to other sources, mostly agricultural sources in the case of N. The observed changes have promoted the designation of the lower reaches of the CR as "affected" by NO3- pollution, and the whole CR watershed as a Nitrate Vulnerable Zone, with the emergent question about whether irrigation implementation as carried out currently in Spain is against the environmental objectives of the Water Framework Directive.

[Differences in variables representative of cardiovascular disease or repercussion between subjects with high cardiovascular risk with and without any family history of early cardiovascular events]. / Diferencias en variables representativas de enfermedad o repercusión cardiovascular entre sujetos de alto riesgo cardiovascular con y sin antecedentes familiares de eventos cardiovasculares precoces.

UNLABELLED: INTRODUCTION, BASES AND AIMS: Study the possible associations between any family history of early heart disease and variables expressive of heart disease, lesion or repercussion in subjects of high cardiovascular risk. MATERIAL AND METHODS: Nationwide cross-sectional study with 2264 consecutive patients in the Outpatient Clinic of Internal Medicine 18 years of age or older and with high or extremely high cardiovascular risk taken from the CIFARC (Integral Control of High Risk Cardiovascular Factors) study run by the SEMI (Spanish Internal Medicine Association) cardiovascular Risk Group. We have studied the relationship between the presence or lack of same in family histories of early heart disease (AFP-Family History of early heart disease, hereafter FH) and different variables in the factors concerning cardiovascular risk and target organ lesion. The statistical treatment (Chi-2, ANOVA and Pearson s linear regression) was performed using the STATISTIX programme. RESULTS AND DISCUSSION: We observed a significative increase (p<0.05) in the group with FH with a percentage of the following variables: Total cholesterol>250 mg/dl, HDL<40 mg/dl, LDL>130 mg/dl, LVH (left ventricular hypertrophy), creatinine 1.2-2mg/dl, retinopathy I-II, serious retinopathy, smoking, proteinuria>300 mg/dl, kidney insufficiency and peripheral vascular disease. This significative increase in the variables under study appeared in males of over 55 years of age and in females of over 65 years of age; nevertheless, this increase in the incidence rate is becoming more common as of age 50 in males, with a maximum in both sexes after the age of 70. No significative differences were noted with regard to sex, BMI (Body Mass Index), atheromatosis, ischemic cardiopathy and cerebrovascular disease. On the whole, subjects of both sexes of the FH group have come to the clinic 3 years earlier than those of the group without FH. CONCLUSIONS: Patients with FH show a greater incidence of certain factors concerning heart risk and target organ lesion.

Diferencias en variables representativas de enfermedad o repercusión cardiovascular entre sujetos de alto riesgo cardiovascular con y sin antecedentes familiares de eventos cardiovasculares precoces / Differences in variables representatives of cardiovascular disease or repercussion between subjects with high cardiovascular risk with and without any family history of early cardiovascular events

Introducción, fundamentos y objetivos: Estudiar las posibles asociaciones entre antecedentes familiares precoces (AFP) de enfermedad cardiovascular y variables expresivas de enfermedad, lesión o repercusión cardiovascular en los sujetos de alto riesgo cardiovascular. Material y métodos: Estudio transversal de ámbito nacional con 2.264 pacientes consecutivos de las Consultas Externas de Medicina Interna, mayores de 18 años y con riesgo cardiovascular alto o muy alto, procedentes del Estudio CIFARC del Grupo de Riesgo Vascular de la SEMI. Se estudia la relación entre la presencia o no de antecedentes familiares de enfermedad cardiovascular precoz (AFP) y distintas variables de factores de riesgo cardiovascular y lesión de órgano diana. El tratamiento estadístico (Chi cuadrado, ANOVA y regresión líneal de Pearson) se ha realizado mediante el programa STATISTIX. Resultados y discusión: Observamos un incremento significativo (p 250 mg/dl, HDL 130 mg/dl, HVI (hipertrofia ventricular izquierda), creatinina 1,2-2 mg/dl, retinopatía I-II, retinopatía grave, tabaquismo, proteinuria > 300 mg/dl, Insuficiencia renal y enfermedad vascular periférica. Este incremento significativo de las variables estudiadas se produce en varones de más de 55 años y en mujeres de más de 65 años; no obstante comienza a observarse este aumento del porcentaje de incidencia a partir de los 50 años en varones, con un máximo en ambos sexos tras los setenta. No se observan diferencias significativas respecto a sexo, IMC (índice de masa corporal) ateromatosis, cardiopatía isquémica y enfermedad cerebrovascular. Existe en general en ambos sexos un adelanto de tres años en el grupo de AFP en acudir a la consulta médica respecto al grupo que no posee AFP. Conclusiones: Los pacientes con AFP presentan mayor incidencia de ciertos factores de riesgo cardiovascular y de lesión de órgano diana

Kikuchi-Fujimoto's disease (KFD), Histiocytic Necrotizing lymphadenitis, is a rare self-limiting condition characterized by lymphadenopathy, fever and neutropenia. The aetiology of KFD is controversial, and its diagnosis is confirmed histologically. Although KFD has rarely been reported associated to Systemic lupus erythemotosus (SLE) should be ruled out given its different prognosis and management. We present the clinical, histological and evolution the two cases of patients with Kikuchi's disease; one case had evolution classic and the other case were associated with SLE.

Were chosen for analysis 1443 acute poisonings, that were treated in the Emergency Services of the Miguel Servet Hospital and the University Hospital of Zaragoza between the years 1988 and 89. The great part of the patients didn't required hospitable ingress, it was observed a predominance of the voluntary poisonings with predominance in people under 40 years. Among the drug poisonings were the benzodiazepines the drug more used and among nonpharmacologic agent, alcohol and the narcotics. The treatment more used was the symptomatic (53%) and was contrast the decrease of gastric lavage (15%) and forced diuresis (10%).
