TL;DR: It is shown that the persistence of Leishmania major in the skin after healing in resistant C57BL/6 mice is controlled by an endogenous population of CD4+CD25+ regulatory T cells, indicating that the equilibrium established between effector and regulatory T Cells in sites of chronic infection might reflect both parasite and host survival strategies.
Abstract: The long-term persistence of pathogens in a host that is also able to maintain strong resistance to reinfection, referred to as concomitant immunity, is a hallmark of certain infectious diseases, including tuberculosis and leishmaniasis. The ability of pathogens to establish latency in immune individuals often has severe consequences for disease reactivation1,2,3. Here we show that the persistence of Leishmania major in the skin after healing in resistant C57BL/6 mice is controlled by an endogenous population of CD4+CD25+ regulatory T cells. These cells constitute 5–10% of peripheral CD4+ T cells in naive mice and humans, and suppress several potentially pathogenic responses in vivo, particularly T-cell responses directed against self-antigens4. During infection by L. major, CD4+CD25+ T cells accumulate in the dermis, where they suppress—by both interleukin-10-dependent and interleukin-10-independent mechanisms—the ability of CD4+CD25- effector T cells to eliminate the parasite from the site. The sterilizing immunity achieved in mice with impaired IL-10 activity is followed by the loss of immunity to reinfection, indicating that the equilibrium established between effector and regulatory T cells in sites of chronic infection might reflect both parasite and host survival strategies.

TL;DR: Medication errors are common in pediatric inpatient settings, and further efforts are needed to reduce them.
Abstract: ContextIatrogenic injuries, including medication errors, are an important problem
in all hospitalized populations. However, few epidemiological data are available
regarding medication errors in the pediatric inpatient setting.ObjectivesTo assess the rates of medication errors, adverse drug events (ADEs),
and potential ADEs; to compare pediatric rates with previously reported adult
rates; to analyze the major types of errors; and to evaluate the potential
impact of prevention strategies.Design, Setting, and PatientsProspective cohort study of 1120 patients admitted to 2 academic institutions
during 6 weeks in April and May of 1999.Main Outcome MeasuresMedication errors, potential ADEs, and ADEs were identified by clinical
staff reports and review of medication order sheets, medication administration
records, and patient charts.ResultsWe reviewed 10 778 medication orders and found 616 medication errors
(5.7%), 115 potential ADEs (1.1%), and 26 ADEs (0.24%). Of the 26 ADEs, 5
(19%) were preventable. While the preventable ADE rate was similar to that
of a previous adult hospital study, the potential ADE rate was 3 times higher.
The rate of potential ADEs was significantly higher in neonates in the neonatal
intensive care unit. Most potential ADEs occurred at the stage of drug ordering
(79%) and involved incorrect dosing (34%), anti-infective drugs (28%), and
intravenous medications (54%). Physician reviewers judged that computerized
physician order entry could potentially have prevented 93% and ward-based
clinical pharmacists 94% of potential ADEs.ConclusionsMedication errors are common in pediatric inpatient settings, and further
efforts are needed to reduce them.

TL;DR: This work provides a broad overview of how histone methylation is regulated and leads to biological outcomes and suggests its links to disease and ageing and possibly to transmission of traits across generations are illustrated.
Abstract: Organisms require an appropriate balance of stability and reversibility in gene expression programmes to maintain cell identity or to enable responses to stimuli; epigenetic regulation is integral to this dynamic control. Post-translational modification of histones by methylation is an important and widespread type of chromatin modification that is known to influence biological processes in the context of development and cellular responses. To evaluate how histone methylation contributes to stable or reversible control, we provide a broad overview of how histone methylation is regulated and leads to biological outcomes. The importance of appropriately maintaining or reprogramming histone methylation is illustrated by its links to disease and ageing and possibly to transmission of traits across generations.

TL;DR: Improving care for intensive care survivors and their families requires collaboration between practitioners and researchers in both the inpatient and outpatient settings, and three major themes emerged from the conference.
Abstract: Background:Millions of patients are discharged from intensive care units annually. These intensive care survivors and their families frequently report a wide range of impairments in their health status which may last for months and years after hospital discharge.Objectives:To report on a 2-day Socie
