Can Large Language Models Aid Caregivers of Pediatric Cancer Patients in Information Seeking? A Cross-Sectional Investigation.

Purpose: Caregivers in pediatric oncology need accurate and understandable information about their child's condition, treatment, and side effects. This study assesses the performance of publicly accessible large language model (LLM)-supported tools in providing valuable and reliable information to caregivers of children with cancer.

Methods: In this cross-sectional study, we evaluated the performance of the four LLM-supported tools-ChatGPT (GPT-4), Google Bard (Gemini Pro), Microsoft Bing Chat, and Google SGE-against a set of frequently asked questions (FAQs) derived from the Children's Oncology Group Family Handbook and expert input (In total, 26 FAQs and 104 generated responses).

Measurable residual disease and posttransplantation gilteritinib maintenance for patients with FLT3-ITD-mutated AML.

BMT CTN 1506 ("MORPHO"; NCT02997202) was a randomized phase 3 study of gilteritinib compared to placebo as maintenance therapy after hematopoietic stem cell transplantation (HCT) for patients with FLT3-ITD-mutated acute myeloid leukemia (AML). A key secondary endpoint was to determine the impact on survival of pre- and/or post-HCT measurable residual disease (MRD), as determined using a highly sensitive assay for FLT3-ITD mutations. Generally, gilteritinib maintenance therapy was associated with improved relapse-free survival (RFS) for participants with detectable peri-HCT MRD, whereas no benefit was evident for those lacking detectable MRD.

Defining the caudal limits of the endoscopic endonasal approach to the craniovertebral junction: anatomic study correlating radiographic measures.

Objective: The endoscopic endonasal approach (EEA), has become the preferred alternative to traditional open and transoral approaches to the ventral craniovertebral junction (CVJ) region. However, preoperative prediction of the limitations of caudal reach remains challenging. This cadaveric study aimed to quantify the CVJ area of exposure and access afforded by the EEA, evaluate the accuracy of previously described radiographic anthropometric lines, and identify the lowest limit of the EEA corridor.

Barriers to orthodox medical care of prostate cancer in Ghana.

Traditional medicine is widely used in sub-Saharan Africa, particularly in Ghana, where it is commonly integrated with modern orthodox medicine. This study examines the barriers that delay the pursuit of orthodox medical care for prostate cancer (PCa) in Ghana's Central region, where a blend of traditional and modern orthodox medicine exists. The preference for indigenous traditional medicine often results in late-stage presentations of PCa, adversely affecting patient outcomes.

Trochlear Nerve Decompression by Endoscopic Suboccipital Supracerebellar Infratentorial Approach: A Technical Note: 2-Dimensional Operative Video.

Background And Importance: Superior oblique myokymia (SOM) is a rare, acquired aberration of the innervation of the superior oblique, resulting in episodic monocular contraction of the superior oblique muscle characterized by intermittent rotatory eye movement causing diplopia and oscillopsia. Several treatment modalities have been described to treat SOM, including medication and surgical interventions. There is a paucity of reports describing microvascular decompression (MVD) of the trochlear nerve near the root entry zone for the treatment of a neurovascular conflict.

Successful Treatment of Mycoplasma genitalium Urethritis With High-Dose Tinidazole.

A 30-year-old male patient with symptomatic Mycoplasma genitalium urethritis failed treatment with oral azithromycin, 2-stage doxycycline-moxifloxacin, and minocycline. Molecular testing confirmed the presence of macrolide resistance mutations. Treatment with oral tinidazole 2 g daily for 7 days resulted in clinical and microbiologic cure.

Emerging role of natural killer cells in non-AIDS comorbidities during suppressive antiretroviral therapy.

Purpose Of Review: Despite decades of insights about the role of natural killer (NK) cells in HIV infection, their persistent dysregulation despite antiretroviral therapy (ART) and its pathological consequences have been incompletely delineated. In this review, we highlight recent findings on the immunophenotypic and functional alterations of NK cells during virally suppressed HIV infection and explore their potential impact on promoting non-AIDS related comorbidities among people living with HIV (PLWH).

Recent Findings: Of note are the apparent persistent activated profiles of NK cells and pathophysiological events such as endoplasmic reticulum (ER) stress in potentially driving NK cell derived inflammation and tissue destruction.

Education strategies are the most commonly used in pediatric rehabilitation implementation research: a scoping review.

Background: Approximately one in six children has a disability, and effective, evidence-based rehabilitation can ameliorate the impact of these conditions over the lifespan. However, implementing interventions in real-world settings remains a challenge. This scoping review aimed to summarize the characteristics, implementation strategies, and outcomes of implementation studies in pediatric rehabilitation.

Complexes of vertebrate TMC1/2 and CIB2/3 proteins form hair-cell mechanotransduction cation channels.

Calcium and integrin-binding protein 2 (CIB2) and CIB3 bind to transmembrane channel-like 1 (TMC1) and TMC2, the pore-forming subunits of the inner-ear mechano-electrical transduction (MET) apparatus. These interactions have been proposed to be functionally relevant across mechanosensory organs and vertebrate species. Here, we show that both CIB2 and CIB3 can form heteromeric complexes with TMC1 and TMC2 and are integral for MET function in mouse cochlea and vestibular end organs as well as in zebrafish inner ear and lateral line.

Exploring the influence of hospital context on acute care physical therapy fall prevention practice: A qualitative study.

Background: Falls are a significant concern for hospitals and patients. The risk of falls is particularly heightened around the period of hospitalization. Physical therapy (PT) is commonly consulted for hospitalized patients at-risk for falls, yet it is unknown how the hospital context influences fall prevention practice among physical therapists.

Effects of intraspecific hybridisation between the northern and the southern populations of the cabbage beetle, on life-history traits.

Significant differences in life-history traits between the southern population (S) and northern (N) population of the cabbage beetle make it an excellent model for studying inheritance in this insect. In the present study, we observed the life-history traits of pure strains, F, reciprocal backcross and reciprocal F progeny under a photoperiod of L:D 15:9 h at 22 °C. The S population had shorter larval development time, longer pupal time, higher body weight, growth rate and weight loss compared with the N population.

Targeting Nerve Fiber Outgrowth Inhibition After Experimental Spinal Cord Injury: A Systematic Review and Meta-analysis of Chondroitinase ABC.

Background: Spinal cord injury (SCI) can impair motor, sensory, and autonomic function. The formation of the glial scar comprises protective as well as inhibitory neurite outgrowth properties operated by the deposition of chondroitin sulfate proteoglycans (CSPG). Chondroitinase ABC (ChABC) can degrade CSPG and foster neuroaxonal plasticity as a therapeutic approach to restore locomotor function after SCI.

Toxic Effects of Butanol in the Plane of the Cell Membrane.

Solvent toxicity limits -butanol fermentation titer, increasing the cost and energy consumption for subsequent separation processes and making biobased production more expensive and energy-intensive than petrochemical approaches. Amphiphilic solvents such as -butanol partition into the cell membrane of fermenting microorganisms, thinning the transverse structure, and eventually causing a loss of membrane potential and cell death. In this work, we demonstrate the deleterious effects of -butanol partitioning upon the lateral dimension of the membrane structure, called membrane domains or lipid rafts.

The potential impact of optimal blood pressure treatment intensity to reduce disparities in dementia between Black and White individuals.

Background: Black adults have higher dementia risk than White adults. Whether tighter population-level blood pressure (BP) control reduces this disparity is unknown.

Objective: Estimate the impact of optimal BP treatment intensity on racial disparities in dementia.

Single-Cell Analysis in Cerebrovascular Research: Primed for Breakthroughs and Clinical Impact.

Data generated using single-cell RNA-sequencing has the potential to transform understanding of the cerebral circulation and advance clinical care. However, the high volume of data, sometimes generated and presented without proper pathophysiological context, can be difficult to interpret and integrate into current understanding of the cerebral circulation and its disorders. Furthermore, heterogeneity in the representation of brain regions and vascular segments makes it difficult to compare results across studies.

Nucleoside Reverse Transcriptase Inhibitor (NRTI)-Induced Neuropathy and Mitochondrial Toxicity: Limitations of the Poly-γ Hypothesis and the Potential Roles of Autophagy and Drug Transport.

Nucleoside reverse transcriptase inhibitors (NRTIs) are the backbone of highly active antiretroviral therapy (HAART)-the current standard of care for treating human immunodeficiency virus (HIV) infection. Despite their efficacy, NRTIs cause numerous treatment-limiting adverse effects, including a distinct peripheral neuropathy, called antiretroviral toxic neuropathy (ATN). ATN primarily affects the extremities with shock-like tingling pain, a pins-and-needles prickling sensation, and numbness.

Oncogenic Functions of Alternatively Spliced Isoform in Retroperitoneal Liposarcoma.

Retroperitoneal liposarcoma (RPLPS) is one of the most common histologic subtypes of soft tissue sarcoma (STS). Complete surgical resection remains the mainstay treatment, while the high rate of locoregional recurrence constitutes the predominant cause of mortality. Well-differentiated (WDLPS) and dedifferentiated (DDLPS) liposarcoma are the most frequent subtypes of RPLPS and present amplified MDM2 gene as a hallmark.

Association of Computed Tomography Scan-Assessed Body Composition with Immune and PI3K/AKT Pathway Proteins in Distinct Breast Cancer Tumor Components.

This hypothesis-generating study aims to examine the extent to which computed tomography-assessed body composition phenotypes are associated with immune and phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) signaling pathways in breast tumors. A total of 52 patients with newly diagnosed breast cancer were classified into four body composition types: adequate (lowest two tertiles of total adipose tissue [TAT]) and highest two tertiles of total skeletal muscle [TSM] areas); high adiposity (highest tertile of TAT and highest two tertiles of TSM); low muscle (lowest tertile of TSM and lowest two tertiles of TAT); and high adiposity with low muscle (highest tertile of TAT and lowest tertile of TSM). Immune and PI3K/AKT pathway proteins were profiled in tumor epithelium and the leukocyte-enriched stromal microenvironment using GeoMx (NanoString).

Extracellular Vesicles from Mesenchymal Stem Cells: Potential as Therapeutics in Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD).

Metabolic dysfunction-associated steatotic liver disease (MASLD) is characterized by the accumulation of triglycerides within hepatocytes, which can progress to more severe conditions, such as metabolic dysfunction-associated steatohepatitis (MASH), which may include progressive fibrosis, leading to cirrhosis, cancer, and death. This goal of this review is to highlight recent research showing the potential of mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) in reducing the key pathogenic pathways of MASLD or MASH. Relevant published studies were identified using PubMed with one or more of the following search terms: MASLD, MASH, NAFLD, NASH, exosome, extracellular vesicle (EV), therapy, and/or mesenchymal stem cells (MSC).
