Fast inhibition slows and desynchronizes mouse auditory efferent neuron activity.

The encoding of acoustic stimuli requires precise neuron timing. Auditory neurons in the cochlear nucleus (CN) and brainstem are well-suited for accurate analysis of fast acoustic signals, given their physiological specializations of fast membrane time constants, fast axonal conduction, and reliable synaptic transmission. The medial olivocochlear (MOC) neurons that provide efferent inhibition of the cochlea reside in the ventral brainstem and participate in these fast neural circuits.

The impact of early direct-contact experiences on reducing mental health stigma among student pharmacists: A pilot study.

Introduction: Mental health-related stigma is a barrier to treatment and recovery for serious mental illnesses (SMIs). Educational training programs demonstrate positive changes in health professional students' attitudes and stigma toward SMI; however, student pharmacists have minimal opportunity to directly engage with the SMI population. This study aims to assess and compare student pharmacists' stigma related to SMI before and after participating in a pilot series of direct-contact workshop experiences.

Catatonia-related adverse outcomes after long-acting injectable antipsychotics: Case series.

Due to a lack of controlled, prospective trials examining the pathophysiology and treatment of catatonia, current guidelines vary regarding how and when to best use antipsychotics in the presence of catatonia and what factors to consider in a thorough risk-benefit analysis. The literature is especially limited in describing the risks and benefits of using long-acting injectable antipsychotics in the presence of catatonia. We describe four cases where patients with preexisting catatonia received long-acting injectable first generation antipsychotics and experienced severe adverse effects (three experienced worsening of catatonia and one experienced neuroleptic malignant syndrome).

Decoding context memories for threat in large-scale neural networks.

Humans are often tasked with determining the degree to which a given situation poses threat. Salient cues present during prior events help bring online memories for context, which plays an informative role in this process. However, it is relatively unknown whether and how individuals use features of the environment to retrieve context memories for threat, enabling accurate inferences about the current level of danger/threat (i.

Sunflower Syndrome: A Survey of Provider Awareness and Management Preferences.

Background: Sunflower syndrome is a rare photosensitive pediatric epilepsy characterized by stereotyped hand-waving in response to bright lights. These stereotyped movements with maintained awareness can be mistaken for a movement disorder. This study assessed neurology providers' diagnostic reasoning, evaluation, and treatment of Sunflower syndrome.

The mechanistic divide in psychedelic neuroscience: An unbridgeable gap?

In recent years, psychedelics have generated considerable excitement and interest as potential novel therapeutics for an array of conditions, with the most advanced evidence base in the treatment of certain severe and/or treatment-resistant psychiatric disorders. An array of clinical and pre-clinical evidence has informed our current understanding of how psychedelics produce profound alterations in consciousness. Mechanisms of psychedelic action include receptor binding and downstream cellular and transcriptional pathways, with long-term impacts on brain structure and function-from the level of single neurons to large-scale circuits.

The novel linkage between and genes regulates sonic hedgehog signaling during mouse embryonic development.

Sonic hedgehog (Shh) signaling regulates embryonic morphogenesis utilizing primary cilia, the cell antenna acting as a signaling hub. Fuz, an effector of planar cell polarity (PCP) signaling, involves Shh signaling via cilia formation, while the G protein-coupled receptor 161 (Gpr161) is a negative regulator of Shh signaling. The range of phenotypic malformations observed in mice bearing mutations in either of these two genes is similar; however, their functional relations have not been previously explored.

Menstrual Irregularities and Amenorrhea in Thyroid Eye Disease Patients Treated With Teprotumumab.

Purpose: To evaluate the rates of amenorrhea and menstrual irregularities in patients with active thyroid eye disease treated with teprotumumab.

Methods: A retrospective review was conducted of patients with active thyroid eye disease treated between 2020 and 2022 at a single institution. Female thyroid eye disease patients with regular menstruation at baseline who completed 8 infusions of teprotumumab were assessed.

Sex-Specific Prognosis of Left Ventricular Size and Function Following Repair of Degenerative Mitral Regurgitation.

Background: Prior studies have demonstrated worse long-term outcomes for women after surgery for severe mitral regurgitation (MR). The current Class I indications for surgery for severe degenerative MR use cutoffs of left ventricular end-systolic dimension (LVESD) and left ventricular ejection fraction (EF) that do not account for known sex-related differences.

Objectives: The primary objective of this study was to assess long-term mortality following mitral valve repair in women compared with men on the basis of preoperative left ventricular systolic dimensions and EF.

Recovery Trajectories in Children Requiring 3 or More Days of Invasive Ventilation.

Objectives: To characterize health-related quality of life (HRQL) and functional recovery trajectories and risk factors for prolonged impairments among critically ill children receiving greater than or equal to 3 days of invasive ventilation.

Design: Prospective cohort study.

Setting: Quaternary children's hospital PICU.

Elucidation of sex from mature Palmer amaranth () leaves using a portable Raman spectrometer.

Palmer amaranth () is a pervasive and troublesome weed species that poses significant challenges to agriculture in the United States. Identifying the sex of Palmer amaranth plants is crucial for developing tailored control measures due to the distinct characteristics and reproductive strategies exhibited by male and female plants. Traditional methods for sex determination are expensive and time-consuming, but recent advancements in spectroscopic techniques offer new possibilities.

Bringing Generalists to Global Health: a Missed Opportunity and Call to Action.

The credo of the generalist physician has always been the promotion of health for all, in every aspect: not just multiple vulnerable organ systems, but multiple social, cultural, and political factors that contribute to poor health and exacerbate health inequity. In recent years, the field of global health has also adopted this same mission: working across both national and clinical specialty borders to improve health for all and end health disparities worldwide. Yet within the Society for General Internal Medicine, and among American generalists, engagement in global health, both within and outside the USA, remains uncommon.

Use of Genetically Modified Organism (GMO)-Containing Food Products in Children.

Families increasingly raise questions about the use of genetically modified organism (GMO)-containing food products. These products are widely found in the US food supply but originate from a narrow list of crops. Although GMO technology could be used to increase the micronutrient content of foods, this does not occur in the United States; instead, GMO technology has been used to make crops resistant to chemical herbicides.

Methods: This is a retrospective cohort study including patients from the National Cancer Database with cervical cancer who underwent radical hysterectomy from 2010 to 2018. Patient demographics, clinical characteristics and survival were compared by race and surgical route.

Integrin signaling is critical for myeloid-mediated support of T-cell acute lymphoblastic leukemia.

We previously found that T-cell acute lymphoblastic leukemia (T-ALL) requires support from tumor-associated myeloid cells, which activate Insulin Like Growth Factor 1 Receptor (IGF1R) signaling in leukemic blasts. However, IGF1 is not sufficient to sustain T-ALL in vitro, implicating additional myeloid-mediated signals in leukemia progression. Here, we find that T-ALL cells require close contact with myeloid cells to survive.
