Neuroendoscopic lavage for posthemorrhagic hydrocephalus of prematurity: preliminary results at a single institution in the United States.

Objective: The current neurosurgical treatment for intraventricular hemorrhage (IVH) of prematurity resulting in posthemorrhagic hydrocephalus (PHH) seeks to reduce intracranial pressure with temporary and then permanent CSF diversion. In contrast, neuroendoscopic lavage (NEL) directly addresses the intraventricular blood that is hypothesized to damage the ependyma and parenchyma, leading to ventricular dilation and hydrocephalus. The authors sought to determine the feasibility of NEL in PHH.

Smartphone accelerometers as tools to study the effect of socioeconomic disparities in neurosurgical outcomes: a multi-institutional retrospective analysis.

Young, female and scientist: exploring barriers, challenges and opportunities.

Different societal, systemic and personal barriers exist at various stages along a female researcher's career that can potentially undermine their success. The equation for women to reach higher positions in STEM is a multivariable one, and while there has been considerable progress towards addressing some of these compared with the past, current solutions are inadequate and do not address all facets. Here, we asked female winners of the FEBS Open Bio poster prize about their experiences regarding barriers they have faced at the predoctoral and postdoctoral stages, their opinions on how these can be addressed and their advice to new students entering a PhD degree.

Methods: This retrospective observational study was done using TriNetX. Patients with neoplasm for which ICIs were approved were stratified into two groups based on ICI use.

Automation of Ultrasonographic Optic Nerve Sheath Diameter Measurement: A Scoping Review.

Intracranial pressure (ICP) monitoring is a cornerstone of neurocritical care in managing severe brain injury. However, current invasive ICP monitoring methods carry significant risks, including infection and intracranial hemorrhage, and are contraindicated in certain clinical situations. Additionally, these methods are not universally available.

Alcohol-induced liver injury is mediated via α4-containing nicotinic acetylcholine receptors expressed in hepatocytes.

Background: Our previous study demonstrated that alcohol induced the expression of the α4 subunit of nicotinic acetylcholine receptors (nAChRs) in the livers of wild type mice (WT), and that whole-body α4 nAChR knockout mice (α4KO) showed protection against alcohol-induced steatosis, inflammation, and injury. Based on these findings, we hypothesized that hepatocyte-specific α4 nAChRs may directly contribute to the detrimental effects of alcohol on the liver.

Methods: Hepatocyte-specific α4 knockout mice (α4HepKO) were generated, and the absence of α4 nAChR was confirmed through PCR of genomic DNA.

Complex lymphatic anomalies.

Complex lymphatic anomalies are unique diseases marked by abnormal lymphatic vessel development and growth. Imaging is crucial in the evaluation and management of complex lymphatic anomalies, with dynamic contrast-enhanced MR lymphangiography emerging as a valuable modality for visualizing abnormal lymphatic structures and informing treatment decisions. This article gives an overview of complex lymphatic anomalies and their management strategies, focusing specifically on generalized lymphatic anomaly, Gorham-Stout disease, Kaposiform lymphangiomatosis, and central conducting lymphatic anomalies.

Surgeon attitudes toward risk stratification in emergency surgery for the elderly: an ESTES cross-sectional survey.

Purpose: Our study explores the utilization of objective tools for preoperative assessment of elderly patients by Emergency General Surgeons (EGS).

Neural cue reactivity and intrinsic functional connectivity in individuals with alcohol use disorder following treatment with topiramate or naltrexone.

Rationale: Both topiramate and naltrexone have been shown to affect neural alcohol cue reactivity in alcohol use disorder (AUD). However, their comparative effects on alcohol cue reactivity are unknown. Moreover, while naltrexone has been found to normalize hyperactive localized network connectivity implicated in AUD, no studies have examined the effect of topiramate on intrinsic functional connectivity or compared functional connectivity between these two widely used medications.

Purpose: Spastic paraplegia type 5 (SPG5) is a rare neurodegenerative disease diagnosed primarily through genetic testing.We identified a specific spinal cord sign on conventional MR imaging to help narrow the scope of genetic screening.

Methods: In 25 patients with SPG5 and 21 healthy controls (HCs), the spinal cord cross sign was evaluated on T2*-weighted imaging.

Multiplex Polymerase Chain Reaction Versus Standard Bacterial Culture in Critically Ill Children With Suspected Pneumonia.

Background: Bacterial lower respiratory tract infection, particularly ventilator-associated pneumonia (VAP), is a significant cause of morbidity and mortality in children who require mechanical ventilation (MV). Microbiologic diagnosis has relied on bacterial culture, but reverse transcriptase polymerase chain reaction (RT-PCR) with bacterial targets is now available for clinical use. We compared the diagnostic performance of tracheal aspirate (TA) multiplex RT-PCR to culture in children requiring MV with suspected lower respiratory tract infection.

A case report of long-latency evoked diaphragm potentials after exposure to acute intermittent hypoxia in post-West Nile virus meningoencephalitis.

We present a case report of a 42-year-old female with post-West Nile virus meningoencephalitis who exhibited unique, long-latency diaphragm potentials evoked by transcranial and cervical magnetic stimulation after exposure to acute intermittent hypoxia (AIH). The subject was recruited for a study investigating AIH effects on respiratory motor function in healthy individuals. She had contracted West Nile virus infection 5 years before assessment that resulted in hospitalization and persistent allodynia but was not reported to the research team.

Arginylation of ⍺-tubulin at E77 regulates microtubule dynamics via MAP1S.

Arginylation is the posttranslational addition of arginine to a protein by arginyltransferase-1 (ATE1). Previous studies have found that ATE1 targets multiple cytoskeletal proteins, and Ate1 deletion causes cytoskeletal defects, including reduced cell motility and adhesion. Some of these defects have been linked to actin arginylation, but the role of other arginylated cytoskeletal proteins has not been studied.

Serious Bacterial Infections and Hepatitis C Virus Among People Who Inject Drugs: A Syndemic or Intertwined Epidemics?

Effects of Iron Impurities and Content on Electrochemical Performance and Oxygen Evolution Selectivity of Nickel Catalysts for Ethanol Oxidation.

Although performance enhancements due to trace Fe incorporation into Ni catalysts for the oxygen evolution reaction (OER) have been well documented, the effects of trace versus bulk Fe incorporation into Ni catalysts for the ethanol oxidation reaction (EOR)─a promising anodic alternative to OER─are unclear. Herein, we perform extensive cyclic voltammetry experiments on Ni-based thin films to show that trace Fe incorporation from electrolyte impurities has a minimal impact on EOR performance, while codeposited Fe significantly suppresses catalytic current (by half at 1.5 V).
