Impact of social determinants of health on the outcomes of Latin American children with Multisystem Inflammatory Syndrome (MIS-C).

Importance: There is growing understanding that Social Determinants of Health (SDH) impact on the outcomes of different pediatric conditions. We aimed to determine whether SDH affect the severity of MIS-C.

Design: Retrospective cohort study, 2021-2023.

Antibiotic transformation in an anaerobic membrane bioreactor linked to membrane biofilm microbial activity.

Although extensive research to date has focused on enhancing removal rates of antibiotics from municipal wastewaters, the transformation products formed by anaerobic treatment processes remain understudied. The present work aims to examine the possible roles that the different microbial communities of an anaerobic membrane bioreactor (AnMBR) play in the transformation of antibiotics during wastewater treatment. As part of this work, sulfamethoxazole, erythromycin, and ampicillin were added in separate stages to the influent of the AnMBR at incremental concentrations of 10, 50, and 250 μg/L each.

Central Nervous System Bleeding After a Lumbar Puncture: Still an Ongoing Complication.

BACKGROUND A lumbar puncture is a procedure performed to uncover the state of the central nervous system by analysis of the cerebrospinal fluid. It is done also to infuse medications in the subdural space. A lumbar puncture should not cause central nervous system bleeding, but this complication is still occurring in certain cases.

A nested deletion approach to generate Cre deleter mice with progressive Hox profiles.

In mice, the loxP/Cre recombinase-dependent system of recombination offers powerful possibilities for engineering genetic configurations of interest. This system can also be advantageously used for conditional mutagenesis in vivo, whenever such an approach is required due to deleterious effects of either one mutation, or a combination thereof. Here, we report on the production of an allelic series of insertions of a Hoxd11/Cre fusion transgene at different positions within the HoxD complex, in order to produce the CRE recombinase with a 'Hox profile' progressively more extended.
