[Clinical and microbiological characteristics of urinary tract infections in the first year after renal transplantation].

Introduction: Urinary tract infections (UTI) are the most frequent infection in kidney transplant (KT) patients. The main objective was to determine the clinical and microbiological characteristics of UTIs that occur during the first year after KT.

Methods: Retrospective cohort study that included patients over 18 years of age who received KT between 2009-2020 in two hospitals in Córdoba city, Argentina.

Infections in the first year after renal transplant.

Infections are frequent complications of kidney transplants. We aimed at determining the frequency and type of infections that occur in renal transplant recipients during the early (0-1 month), intermediate (1-6 months) and late (6-12 months) post-transplant period and analyzing the risk factors for infection. To this aim, we conducted a retrospective cohort study on 1-year post-transplant follow-up in two third-level university hospitals in Cordoba city.

Searching Behavior of Cryptolaemus montrouzieri (Coleoptera: Coccinellidae) in Response to Mealybug Sex Pheromones.

Cryptolaemus montrouzieri (Mulsant) (Coleoptera: Coccinellidae) is a predatory insect widely commercialized for the augmentative biological control of mealybugs (Hemiptera: Pseudococcidae). Though visual factors that guide this predator to its prey have been reported, the chemical cues that they may also use have not been well studied. In this study, the response of C.

Reduced intellectual development in children with prenatal lead exposure.

Objective: Low-level postnatal lead exposure is associated with poor intellectual development in children, although effects of prenatal exposure are less well studied. We hypothesized that prenatal lead exposure would have a more powerful and lasting impact on child development than postnatal exposure.

Design: We used generalized linear mixed models with random intercept and slope to analyze the pattern of lead effect of the cohort from pregnancy through 10 years of age on child IQ from 6 to 10 years.

Blood lead secular trend in a cohort of children in Mexico City (1987-2002).

We determined the secular trend in blood lead levels in a cohort of 321 children born in Mexico City between 1987 and 1992. Blood lead level was measured every 6 months during a 10-year period. We modeled the effect of yearly air lead concentration nested within the calendar year in which the child was born, family use of lead-glazed pottery, socioeconomic status, year in which the child was born, age of the child at the time of blood lead measurement, place of residence, and an indicator variable for subjects with complete or incomplete blood lead values.
