Silicone Breast Implant as a Hidden Cause of Fever: A Diagnostic Pitfall.

A 56-year-old woman developed a persistent fever following right transurethral ureterolithotripsy. Approximately two weeks prior to the onset of fever, she had sustained chest trauma and had a 20-year history of bilateral silicone breast implants. Physical examination, including breast assessment, was unremarkable.

EXT1/EXT2-Associated Membranous Nephropathy Secondary to TAFRO Syndrome: A Case Report.

Introduction: Renal involvement in TAFRO syndrome usually presents as acute kidney injury with oligoproteinuria. Renal pathology is typically characterized by glomerular microangiopathy without immune deposits, and there have been no reports of membranous nephropathy. While idiopathic multicentric Castleman disease (iMCD), which shares a similar pathophysiology with TAFRO syndrome, has documented several cases of membranous nephropathy, the underlying mechanisms remain unclear.

Microbiota-driven antitumour immunity mediated by dendritic cell migration.

Gut microbiota influence the antitumour efficacy of immune checkpoint blockade, but the mechanisms of action have not been fully elucidated. Here, we show that a new strain of the bacterial genus Hominenteromicrobium (designated YB328) isolated from the faeces of patients who responded to programmed cell death 1 (PD-1) blockade augmented antitumour responses in mice. YB328 activated tumour-specific CD8 T cells through the stimulation of CD103CD11b conventional dendritic cells (cDCs), which, following exposure in the gut, migrated to the tumour microenvironment.

Acute kidney injury does not explain sex differences in kidney replacement therapy initiation or death amongst individuals with chronic kidney disease reported to the UK Renal Registry.

Background: Why more males than females start kidney replacement therapy (KRT) is incompletely understood. Acute kidney injury (AKI) is a possible factor underlying sex differences in chronic kidney disease (CKD) progression, but previous studies regarding this have been inconclusive. We investigated sex differences in the association between AKI and CKD progression in UK nephrology care.

Novel TEAD1 Inhibitor VT103 Enhances Dabrafenib Efficacy in BRAF V600E Mutated Lung Adenocarcinoma via Survivin Downregulation.

The BRAF V600E mutation is observed in 2% of the patients with lung adenocarcinoma (LUAD), and combination therapy targeting BRAF and mitogen-activated protein kinase (MEK) is the standard treatment for this population. However, acquired resistance inevitably develops, which highlights the need for novel therapeutic strategies. In this study, we established a patient-derived BRAF V600E-mutated LUAD cell line, KTOR81, and investigated the potential of targeting the Yes-associated protein 1 (YAP1)/transcriptional enhanced associate domain 1 (TEAD1) pathway in combination with BRAF inhibition.

Methanol-induced transcription factor Mpp1 regulates the coordinated expression of multiple genes to achieve a balanced C1 metabolism in the methylotrophic yeast .

Unlabelled: Methylotrophic yeasts can grow on methanol as the sole carbon and energy source. They have been used as hosts for heterologous protein production, which is achieved by their strongly and tightly regulated methanol-induced gene promoters. The expression levels of methanol-induced genes, such as and , are regulated by concentration-regulated methanol induction (CRMI).

Clinical and molecular landscape of prolonged SARS-CoV-2 infection with resistance to remdesivir in immunocompromised patients.

Patients with hematologic diseases have experienced coronavirus disease 2019 (COVID-19) with a prolonged, progressive course. Here, we present clinical, pathological, and virological analyses of three cases of prolonged COVID-19 among patients undergoing treatment for B-cell lymphoma. These patients had all been treated with anti-CD20 antibody and bendamustine.

Factors affecting diagnostic difficulties in aseptic meningitis: a retrospective observational study.

Objectives: The purpose of this study was to determine the actual diagnostic status of aseptic meningitis and consider the factors that cause difficulties in its diagnosis.

Methods: This study retrospectively reviewed the medical records of aseptic meningitis treated at our hospital from 2013 to 2022 and compared biometric data to distinguish between timely diagnose and difficult diagnose cases.

Results: This retrospective observational study included 127 patients aged 18 years or older.

Positive Murphy's Sign of Fitz-Hugh-Curtis Syndrome.

A Japanese woman in her 30s presented to the emergency department at midnight with right upper quadrant pain that had lasted for a week. Without a definitive diagnosis, she was prescribed acetaminophen and levofloxacin and discharged. When her pain persisted the next morning, she visited her primary care physician and reported fever and right upper quadrant pain.

Exploratory study to examine the neuroendocrinological changes in typically developing adults during a music-related participatory practice using computer software.

There has been a growing recognition of the benefits of participating in art practices for promoting well-being and social connection. Despite this, only a limited number of studies have assessed the neuroendocrinological changes that might contribute to these benefits. In this exploratory study, we focused on a creative activity related to music composition using digital tools.

Preventable diagnostic errors of lower gastrointestinal perforation: a secondary analysis of a large-scale multicenter retrospective study.

Background: Lower gastrointestinal perforation (LGP) is an acute abdominal condition associated with a high mortality rate. Timely and accurate diagnosis is crucial. Nevertheless, a diagnostic delay has been estimated to occur in approximately one-third of the cases, and the factors contributing to this delay are yet to be clearly understood.

A Case of IgG4-Related Disease Manifesting as Extensive Abdominal Periarteritis and Membranous Nephropathy, Successfully Controlled with Low-Dose Steroid Therapy without Relapse or Complications.

Introduction: IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory disease that can affect nearly every organ system, including blood vessels and the kidney. IgG4-related vascular lesions mainly involve the aorta, and the dominant renal manifestation is tubulointerstitial nephritis (TIN). Here, we report a case of IgG4-RD demonstrating extensive abdominal periarteritis and membranous nephropathy (MN).

Impaired immunoproteasomal function exacerbates renal ischemia-reperfusion injury.

Oxidative stress caused by reactive oxygen species (ROS) is involved in the pathogenesis of renal ischemia-reperfusion injury (I/R injury), a major cause of acute kidney injury and delayed graft function (DGF). DGF is an early transplant complication that worsens graft prognosis and patient survival, but the underlying molecular changes are unclear. The proteasome is a multicatalytic enzyme complex that degrades both normal and damaged proteins, and recent studies have revealed that the immunoproteasome, a specific proteasome isoform whose proteolytic activity enhances the generation of antigenic peptides, plays critical roles in the cellular response against oxidative stress.

Oral Supplementation of L-Carnosine Attenuates Acute-Stress-Induced Corticosterone Release and Mitigates Anxiety in CD157 Knockout Mice.

Corticosterone, an end product of the hypothalamic-pituitary-adrenal (HPA) axis, is a crucial stress hormone. A dysregulated HPA axis and corticosterone release play pivotal roles in the onset and persistence of symptoms of stress-related psychiatric disorders, such as anxiety. The intake of nutrients, probiotics, and prebiotic supplements decreases blood corticosterone levels.

Performance status improvement and advances in systemic treatment after brain metastases resection: a retrospective single-center cohort study of non-small cell lung cancer patients.

Background: Brain metastasis (BrM) is prevalent among patients with NSCLC, and surgical resection of BrM constitutes a promising treatment strategy for local management and histopathological diagnosis, although it is offered for a select group of patients. Limited information exists concerning the improvement in performance status (PS) following BrM resection or the outcomes stratified by subsequent systemic therapy.

Methods: We conducted a retrospective single-center cohort study including NSCLC patients with surgically resected BrM and focused on the improvement in PS and subsequent therapy after BrM resection.

Evaluating Cellularity Estimation Methods: Comparing AI Counting with Pathologists' Visual Estimates.

The development of next-generation sequencing (NGS) has enabled the discovery of cancer-specific driver gene alternations, making precision medicine possible. However, accurate genetic testing requires a sufficient amount of tumor cells in the specimen. The evaluation of tumor content ratio (TCR) from hematoxylin and eosin (H&E)-stained images has been found to vary between pathologists, making it an important challenge to obtain an accurate TCR.

Transcription factor Nrf2 activation regulates NETosis, endothelial injury, and kidney disease in myeloperoxidase-positive antineutrophil cytoplasmic antibody-associated vasculitis.

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a systemic autoimmune disease pathologically characterized by vascular necrosis with inflammation. During AAV development, activated neutrophils produce reactive oxygen species (ROS), leading to the aberrant formation of neutrophil extracellular traps (NETs) via NETosis and subsequent fibrinoid vascular necrosis. Nuclear factor-erythroid 2-related factor 2 (Nrf2) functions as an intracellular defense system to counteract oxidative stress by providing antioxidant properties.

Utility of the refined EBMT diagnostic and severity criteria 2023 for sinusoidal obstruction syndrome/veno-occlusive disease.

Sinusoidal obstruction syndrome/veno-occlusive disease (SOS/VOD) is a life-threatening complication of hematopoietic stem cell transplantation (HSCT). Early diagnosis of SOS/VOD is associated with improved clinical outcomes. In 2023, the refined European Society for Blood and Marrow Transplantation diagnostic and severity criteria (refined EBMT criteria 2023) have been advocated.
