kinact/KI ratio of nafithromycin was 3- to 153-fold lower than comparator drugs, further substantiating its lower affinity for CYP3A4/5. In sum, weaker inhibition and lower kinact/KI ratio for CYP3A4/5, points towards nafithromycin’s lower propensities towards clinical drug-drug interactions as compared to other macrolides/ketolides antibiotics.In the field of neuroscience, despite the fact that the proportion of peer-reviewed publications authored by women has increased in recent decades, the proportion of citations of women-led publications has not seen a commensurate increase In five broad-scope journals, citations of papers first- and/or last-authored by women have been shown to be fewer than would be expected if gender was not a factor in citation decisions [Dworkin, J. D., Linn, K. A., Teich, E. G., Zurn, P., Shinohara, R. T., & Bassett, D. S. The extent and drivers of gender imbalance in neuroscience reference lists. Nature Neuroscience, 23, 918-926, 2020]. Given the important implications that such underrepresentation may have on the careers of women researchers, it is important to determine whether this same trend is true in subdisciplines of the field, where interventions might be more targeted. Here, we report the results of an extension of the analyses carried out by Dworkin et al. (2020) to citation patterns in the Journal of Cognitive Neuroscience. The results indicate that the underrepresentation of women-led publications in reference sections is also characteristic of papers published in Journal of Cognitive Neuroscience over the past decade. Furthermore, this pattern of citation imbalances is present regardless of author gender, implicating systemic factors. These results contribute to the growing body of evidence that intentional action is needed to address inequities in the way that we carry out and communicate our science.Quickly preventing the retrieval of (inappropriate) long-term memories might recruit a similar control mechanism as rapid action-stopping. A very specific characteristic of rapid action-stopping is “global motor suppression” When a single response is rapidly stopped, there is a broad skeletomotor suppression. This is shown by the technique of TMS placed over a task-irrelevant part of the primary motor cortex (M1) to measure motor-evoked potentials. Here, we used this same TMS method to test if rapidly preventing long-term memory retrieval also shows this broad skeletomotor suppression effect. Twenty human participants underwent a Think/No-Think task. In the first phase, they learned word pairs. In the second phase, they received the left-hand word as a cue and had to either retrieve the associated right-hand word (“Think”) or stop retrieval (“No-Think”). At the end of each trial, they reported whether they had experienced an intrusion of the associated memory. Behaviorally, on No-Think trials, they reported fewer intrusions than Think trials, and the reporting of intrusions decreased with practice. Physiologically, we observed that the motor-evoked potential, measured from the hand (which was irrelevant to the task), was reduced on No-Think trials in the time frame of 300-500 msec, especially on trials where they did report an intrusion. This unexpected result contradicted our preregistered prediction that we would find such a decrease on No-Think trials where the intrusion was not reported. read more These data suggest that one form of executive control over (inappropriate) long-term memory retrieval is a rapid and broad stop, akin to action-stopping, that is triggered by the intrusion itself.
Atopic dermatitis (AD) is a chronic inflammatory skin condition characterized by erythematous lesions, pruritus, and a skin barrier defect. Long-term treatment in children is challenging, as there is only one Food and Drug Administration-approved systemic medication. Current treatments may have limited efficacy or serious side effects in children. With a deeper understanding of AD pathogenesis and the advent of target-specific medications, several biologics are undergoing clinical trials for future use in pediatric AD.
This article reviews the current and emerging biologic therapies for treatment of pediatric AD. It allows for comprehensive comparison of medications and their clinical trials to help providers optimize patient treatment plans while providing expert insight into upcoming advancements in the treatment of pediatric AD.
Treating pediatric AD is complicated given the variety of disease severity, psychosocial impact, and relative lack of approved medications for severe disease. Given the safety data on dupilumab, newer biologics will likely be second-line. We do not yet understand the long-term impact of newer biologics on an immature immune system, nor do we fully understand their risks and toxicities. We should proceed optimistically, yet cautiously, with the study of biologics in children.

Despite organophosphate pesticide is the most prevalent cause of acute poisoning in low- and middle-income countries, data on organophosphate induced delayed neuropathy (OPIDN) are limited. We aimed to characterize organophosphates’ long-term effects on the peripheral nervous system after an acute cholinergic crisis in adults.
We performed a prospective observational study in an academic hospital of north India in patients aged 13-40 years with acute organophosphate ingestion. After resolving the cholinergic crisis, the patients were followed for six months with neurologic assessments, including history, neurologic examination, and nerve conduction study (NCS).
Twenty-three patients were recruited to the study. All but one had normal neurological examination and NCS at discharge from hospital a median duration of six days (interquartile range, 3-10) after self-poisoning. Eight (34.8%) developed OPIDN during the six-month follow-up. Three patients had symptomatic neuropathy, and NCS detected subclinical peripheral nerve involvement in five.
