Meropenem is a widely prescribed beta-lactam for hospitalized patients. There are few data on meropenem allergy assessments in inpatients with a reported history of penicillin allergy who require a treatment with meropenem. This can lead to the use of less effective second-line antibiotics that may increase antibiotic resistances. We aimed to evaluate the clinical outcomes of a meropenem allergy assessment in admitted patients with a reported history of penicillin allergy that required meropenem for the treatment of an acute infection.

La obesidad es considerada un factor de riesgo en casos graves de la COVID-19, habiendo sido analizada mediante el índice de masa corporal (IMC), estimador que no correlaciona adecuadamente con el porcentaje de grasa corporal (GC). El objetivo de este estudio ha sido analizar la fracción atribuible poblacional a la GC en formas graves de COVID-19 atendiendo al IMC y al CUN-BAE.

This study investigates wolf (Canis lupus) dietary preferences and their geographical variation by calculating frequency of occurrence and biomass consumption in three areas in the north-western Iberian Peninsula that differ in terms of the type and abundance of potential prey. Wolf dietary preferences were expected to be related to the availability of a species of free-roaming horses (Equus ferus atlanticus) and much less to traditional livestock in each habitat.

Background:Lentils seem to be the most common legume implicated in pediatric allergic patients in the Mediterranean area. However, no lentil allergen has been isolated and characterized. Objective:We sought to purify and characterize relevant IgE-binding proteins from boiled lentil extracts. Methods:IgE-binding proteins from crude and boiled lentil extracts were detected with a pool of sera from patients with lentil allergy. Allergens were isolated by gel-filtration chromatography followed by cation- and anion-exchange chromatography or by reverse-phase HPLC. Their characterization included N-terminal amino acid sequencing, complex asparagine-linked glycan detection, specific IgE immunodetection with 22 individual sera from allergic patients, and immunoblot and CAP inhibition assays. Results:Heat treatment of lentils produced substantial changes in the SDS-PAGE patterns of whole extracts, mainly a strong increase of 12- to 16-kd bands and a decrease of 25- to 45-kd components. Major IgE-binding proteins from the boiled lentil extract were located in the 12- to 16-kd and 45- to 70-kd ranges. Two allergens of 16 kd, proteins L1 and L2, and another one of 12 kd, protein L3, were purified. N-terminal sequencing indicated that all 3 were related and allowed their identification as γ-vicilin subunits. Protein L1 was recognized by 68% of the individual sera tested and inhibited 64% of the IgE binding by commercial lentil CAPs. A second type of allergen of 66 kd, named protein H, was also isolated and identified as a seed-specific biotinylated protein. Protein H reacted with 41% of the individual sera and produced 45% inhibition in CAP inhibition assays. Conclusions:Two different types of allergens have been identified in boiled lentils. Those of 12 to 16 kd, called Len c 1, correspond to γ-vicilin subunits, and those of 66 kd, designated Len c 2, correspond to seed-specific biotinylated protein. Homology with proteins from other legume species can explain potential cross-reactions among these foods. (J Allergy Clin Immunol 2000;106:955-61.)

•The Iron Age village of La Hoya in Iberia was frozen in time by a violent attack.•Isotope results suggest a complex and well-developed mixed economy at that time.•There is variability in manuring and watering of crops and livestock management.•Adult and adolescent diets seem to be based on C3cereals and domestic ungulates.•C4crops such as millet may play a key role in infant and child feeding practices.
