Erythrocytapheresis as a strategy to manage anemia and iron overload in nondeletional hemoglobin H disease.

Hemoglobin H (HbH) disease is associated with anemia, ineffective erythropoiesis, and iron overload. We report a case of a patient with HbH/Hb Constant Spring disease, who was maintained on chronic transfusions as an adult due to symptomatic anemia. Over time, he developed iron overload and was started on chelation therapy but did not have an adequate response to chelation.

Metastatic Insulinoma Managed With Continuous Glucose Monitoring in a Young Female Patient.

Insulinomas are rare neuroendocrine neoplasms and causes of hypoglycemia. They present with neuroglycopenic symptoms, including confusion and seizures. Suspected diagnosis must be confirmed through bloodwork and imaging.

Serum metabolomic signatures of patients with rare neurogenetic diseases: an insight into potential biomarkers and treatment targets.

Introduction: To further advance our understanding of Muscular Dystrophies (MDs) and Spinocerebellar Ataxias (SCAs), it is necessary to identify the biological patterns associated with disease pathology. Although progress has been made in the fields of genetics and transcriptomics, there is a need for proteomics and metabolomics studies. The present study aimed to be the first to document serum metabolic signatures of MDs (DMD, BMD, and LGMD 2A) SCAs (SCA 1-3), from a South Asian perspective.

Immortalization of epidural fat-derived mesenchymal stem cells: characterization and adipocyte differentiation potential.

Background: Mesenchymal stem cells (MSCs) are promising candidates for regenerative therapy due to their self-renewal capability, multilineage differentiation potential, and immunomodulatory effects. The molecular characteristics of MSCs are influenced by their location. Recently, epidural fat (EF) and EF-derived MSCs (EF-MSCs) have garnered attention due to their potential benefits to the spinal microenvironment and their high expression of neural SC markers.

Case report: Potential physiological sources of the late response in epidural spinal recordings induced by spinal cord stimulation during intraoperative neuromonitoring.

Objective: This study aims to investigate the sources of later response in epidural spinal recordings (ESRs) obtained from implanted leads during spinal cord stimulation, a topic has not been widely studied in previous research.

Methods: Two patients with lower back and lower extremity pain underwent SCS implantation with intraoperative neuromonitoring (IONM). The timing of extracted peaks in ESRs and intramuscular electromyography (EMG) recordings were analyzed and compared to a Monte Carlo simulation for synchronization analysis.

Successful management of Leydig Cell Tumor in a 65-year-Old patient: A rare case report.

Leydig cell tumors (LCTs) are rare testicular neoplasms, representing 1-3% of all testicular tumors. A 65-year-old male presented with a painless left scrotal mass. Ultrasound revealed a 61 × 53 × 35 mm tumor with heterogeneous echogenicity and abundant blood supply.

To improve the understanding and treatment level of urogenital nerve fibroma by sharing the clinical manifestations, imaging features, and pathological characteristics of a case of urogenital nerve fibroma.The patient was a middle-aged male with initial symptoms of painless gross hematuria, bladder irritation, and pelvic mass. Imaging examination showed a bladder mass, and transurethral bladder tumor resection was performed to reduce the tumor.

Quantitative assessment of the generalizability of a brain tumor Raman spectroscopy machine learning model to various tumor types including astrocytoma and oligodendroglioma.

Significance: Maximal safe resection of brain tumors can be performed by neurosurgeons through the use of accurate and practical guidance tools that provide real-time information during surgery. Current established adjuvant intraoperative technologies include neuronavigation guidance, intraoperative imaging (MRI and ultrasound), and 5-ALA for fluorescence-guided surgery.

Aim: We have developed intraoperative Raman spectroscopy as a real-time decision support system for neurosurgical guidance in brain tumors.

DDX21 Is a Potential Biomarker for Predicting Recurrence and Prognosis in Hepatocellular Carcinoma.

DEAD-box helicase 21 (DDX21) is a conserved Asp-Glu-Ala-Asp (DEAD) box RNA helicase with multiple functions that is involved in various cellular processes and diseases. However, the role of DDX21 in the recurrence and prognosis of hepatocellular carcinoma (HCC) patients remains unknown. In the current study, we examined the protein expression of DDX21 in HCC tissues through immunohistochemical staining and analyzed the correlation between DDX21 protein expression and clinical outcome via Kaplan-Meier survival analysis.

Molecular dynamics of chemotactic signalling orchestrates dental pulp stem cell fibrosis during aging.

Aging often triggers dental pulp fibrosis, resulting in clinical repercussions such as increased susceptibility to dental infections, compromised tooth vitality, and reduced responsiveness to dental interventions. Despite its prevalence, the precise molecular mechanisms underlying this condition remains unclear. Leveraging single-cell transcriptome analysis from both our own and publicly available datasets, we identified Ccrl2 macrophages as particularly vulnerable during the early stages of aging.

The utilization of microbial cell-free DNA next-generation sequencing for the detection of human herpesvirus-8 in a quaternary care center.

Background: Human herpesvirus-8 (HHV8) can present with cutaneous or extracutaneous manifestations. While violaceous skin lesions characterize cutaneous Kaposi sarcoma, extracutaneous HHV8 is challenging to diagnose due to nonspecific symptoms.

Objectives: We evaluated the role of microbial cell-free DNA next-generation sequencing (mcfDNA NGS) in diagnosing HHV8-related illness.

Interventions That Failed: Factors Associated with the Continuation of Bullying After a Targeted Intervention.

We examined how often teachers' targeted interventions fail in stopping bullying and to what extent this varies between schools vs. between students involved. In addition, we investigated which student-level factors were associated with intervention failure.

Serum Vitamin D Level Correlates Significantly With Leptin and Tumor Necrosis Factor-Alpha in Overweight Postmenopausal Women With Hypertension.

Background: Association of serum vitamin D (vitD) with leptin (Lep) and tumor necrosis factor-alpha (TNF-α) is not precisely known in overweight hypertensive (OW-HT) postmenopausal (PMP) women. Hence, the present study was carried out to investigate the body mass index (BMI)-based correlation of serum vitD with Lep and TNF-α in OW-HT PMP women.

Methods: Women subjects in their early PMP (n = 346, age: 51 - 60 years) categorized into three groups had main inclusion criteria of specified range of age, BMI and blood pressure (BP).

Oral supplementation with propionate is reflected in the serum of healthy individuals.

Background: Short-chain fatty acids (SCFAs), including propionic acid (PA), are key in immunological research. Supplementing PA has shown benefits for autoimmune diseases. A comprehensive understanding of the PA pharmacokinetics is essential for the optimal design and execution of studies utilizing orally administered PA.

Caspase-4 Has Potential Utility as a Colorectal Tissue Biomarker for Dysplasia and Early-Stage Cancer.

Background And Aims: Colorectal cancer (CRC) is the second most deadly cancer globally. The rapidly rising incidence rate of CRC, coupled with increased diagnoses in individuals <50 years, indicates that early detection of CRC, and those at an increased risk of CRC development, is paramount to improve the survival rates of these patients. Here, we profile caspase-4 expression across 2 distinct CRC development pathways, sporadic CRC (sCRC) and inflammatory bowel disease-associated CRC (IBD-CRC), to examine its utility as a novel biomarker for CRC risk and diagnosis.

Characterization of Pancreatic Collagen-Expressing Fibroblasts in Mouse Acute Pancreatitis.

Background And Aims: Pancreatic stellate cells (PSCs) are critical mediators in chronic pancreatitis with an undefined role in acute pancreatitis (AP). PSCs consist of a heterogenous group of cells and are considered interchangeable with pancreatic fibroblasts. This study explored the heterogeneous nature of PSCs by characterizing pancreatic collagen-expressing fibroblasts (PCFs) via lineage tracing in mouse normal and AP pancreas and determining the effect of PCF depletion in AP.

The Varying Histology of Hepatic Sarcoidosis and the Relation of Bile Duct Damage and Loss to the Presence of Portal Hypertension and Cirrhosis.
