The presence of hypothermia among young infants in the emergency department may be a sign of serious or invasive bacterial infections, or invasive herpes simplex viral infection. However, hypothermia may also occur due to a variety of other infectious and noninfectious conditions or environmental exposure. In some settings, hypothermia may represent a protective, energy-conserving response to illness.

Cochlear inner hair cells (IHCs) and outer hair cells (OHCs) require different transcription factors for their cell fate stabilization and survival, suggesting separate mechanisms are involved. Here, we found that the transcription factor Casz1 was crucial for early IHC fate consolidation and for OHC survival during mouse development. Loss of Casz1 resulted in transdifferentiation of IHCs into OHCs, without affecting OHC production.

Importance: Triple-negative breast cancer is an aggressive subtype with a high incidence in young patients, a high incidence in non-Hispanic Black women, and a high risk of progression to metastatic cancer, a devastating sequela with a 12- to 18-month life expectancy. Until recently, one strategy for treating early-stage triple-negative breast cancer was chemotherapy after surgery. However, it was not known whether the addition of immune therapy to postsurgery chemotherapy would be beneficial.

Melatonin, renowned for regulating sleep-wake cycles, also exhibits notable anti-aging properties for the skin. Synthesized in the pineal gland and various tissues including the skin, melatonin's efficacy arises from its capacity to combat oxidative stress and shield the skin from ultraviolet (UV)-induced damage. Moreover, it curbs melanin production, thereby potentially ameliorating hyperpigmentation.

Compared to our closest primate relatives, human life history involves greater longevity, which includes a distinctive postmenopausal life stage. Given mammalian reproductive physiology in which females build a finite stock of cells that can become oocytes early in life, which then continuously deplete mostly through cell death while males produce new sperm throughout adulthood, the postmenopausal stage makes the sex ratio in the fertile pool, called the adult sex ratio (ASR), male biased. Additionally, this affects a more fine-grained ratio, the operational sex ratio (OSR), defined as the ratio of males to females currently able to conceive.

What Physicians Should Consider When Moving Academic Institutions.

South Med J

February 2025

the Department of Emergency Medicine, University of Utah, Salt Lake City.

There is limited information and guidance for physicians transitioning from one academic institution to another. The following recommendations serve as a resource for academic faculty interested in moving to a different academic institution. The advice falls into three categories of preparation: self-reflection and discernment to determine personal preferences and professional priorities; considerations when preparing for an academic faculty interview; and aspects of the offer, opportunity, and negotiables to discern whether it is right.

Cost reduction is an often-cited reason to use telemedicine. In assessing telemedicine's cost and value, providers often turn to published cost analyses in the scientific literature for guidance. In this commentary on existing telemedicine cost analysis literature, we discuss the generalizability of these analyses and identify the Consolidated Framework for Implementation Research framework to help assess the applicability of a given cost analysis using inner- and outer-setting constructs.

Assessing sex as a biological variable is critical to determining the influence of environmental and lifestyle risks and protective factors mediating behavior and neuroplasticity across the lifespan. We investigated sex differences in affective behavior, memory, and hippocampal neurogenesis following short- or long-term exposure to exercise or chronic mild stress in young and aged mice. Male and female mice were assigned control, running, or chronic stress rearing conditions for 1 month (young) or for 15 months (aged), then underwent a behavioral test battery to assess activity, affective behavior, and memory.

Background: Fetal growth restriction (FGR) is a leading risk factor for stillbirth, yet the diagnosis of FGR confers considerable prognostic uncertainty, as most infants with FGR do not experience any morbidity. Our objective was to use data from a large, deeply phenotyped observational obstetric cohort to develop a probabilistic graphical model (PGM), a type of "explainable artificial intelligence (AI)", as a potential framework to better understand how interrelated variables contribute to perinatal morbidity risk in FGR.

Methods: Using data from 9,558 pregnancies delivered at ≥ 20 weeks with available outcome data, we derived and validated a PGM using randomly selected sub-cohorts of 80% (n = 7645) and 20% (n = 1,912), respectively, to discriminate cases of FGR resulting in composite perinatal morbidity from those that did not.

Sci Rep

January 2025

Nano-fabricated Energy Devices Lab, School of Electrical and Computer Eng., University of Tehran, 14395-515, Tehran, Iran.

Core-shell silicon/multiwall carbon nanotubes are one of the most promising anode candidates for further improvement of lithium-ion batteries. Sufficient accommodation for massive volume expansion of silicon during the lithiation process and preventing pulverization and delamination with easy fabrication processes are still critical issues for practical applications. In this study, core-shell silicon/MWCNTs anode materials were synthesized using a facile and controllable PECVD technique to realize aligned MWCNTs followed by a silicon sputtering step.

MuSK regulates neuromuscular junction Nav1.4 localization and excitability.

J Neurosci

January 2025

Carney Institute for Brain Science, Brown University, Providence, RI 02912

The neuromuscular junction (NMJ) is the linchpin of nerve-evoked muscle contraction. Broadly, the function of the NMJ is to transduce nerve action potentials into muscle fiber action potentials (MFAPs). Efficient neuromuscular transmission requires both cholinergic signaling, responsible for generation of endplate potentials (EPPs), and excitation, the amplification of the EPP by postsynaptic voltage-gated sodium channels (Nav1.
