Abstract Crimean-Congo hemorrhagic fever virus (CCHFV) is a highly pathogenic agent. Thus far, vaccines and specific antiviral therapies are not available against the threat of infection. Our knowledge regarding its pathogenesis is indeed limited, and thus, developing effective antiviral therapies is hampered. Several studies have demonstrated that the CCHFV infection has an impact on numerous signal transduction pathways. In parallel, the Wnt signaling pathway components are...

Abstract Ruxolitinib is a targeted drug to treat myelofibrosis (MF). Ruxolitinib has significant advantages in spleen reduction and increasing 5-year overall survival (OS), and ruxolitinib-based combinations might provide more benefits than ruxolitinib monotherapy. In this review, we focus on the data of ruxolitinib-based combinations therapies and treatment-related adverse events (AEs) and safety. We analyzed and summarized the data of ruxolitinib-based combinations. Ruxolitinib...

Abstract Epstein-Barr virus (EBV) positivity in diffuse large B cell lymphoma (DLBCL) provokes a critical oncogenic mechanism to activate intracellular signaling by LMP1. LMP1 specifically mimics the role of BTK-dependent B cell receptor. Therefore, a trial considering RCHOP therapy along with ibrutinib (I-RCHOP) in combination was conducted among patients with EBV-positive DLBCL. This study was an open-label, single-arm, prospective multicenter phase II clinical trial. Patients...

Abstract To ensure adequate reliability (i.e., internal consistency), it is common in studies using event‐related brain potentials (ERPs) to exclude participants for having too few trials. This practice is particularly relevant for error‐related ERPs, such as error‐related negativity (ERN), where the number of recorded ERN trials is not entirely under the researcher's control. Furthermore, there is a widespread practice of inferring reliability based on published psychometric research, which assumes...

Abstract Although economists have suggested that humans generally prioritize maximizing their own self‐interest rather than others’ when distributing rewards, recent psychological studies have shown that people are hyperaltruistic when allocating physical harm to themselves and others during moral decision‐making. However, little is known about how the neurocognitive mechanisms underlying self‐relevance modulate this behavioral tendency under different degrees of physical harm. This study adopted...

Summary Background and Objective Thyrotoxicosis is associated with accelerated bone turnover and increases the risk of fractures and osteoporosis. Graves’ disease is the most common cause of hyperthyroidism. However, studies that examined risk factors associated with fragility fractures only in patients with Graves’ disease are limited. Here we investigated whether the risk of vertebral fracture (VF) of postmenopausal Graves’ disease patients is high and tried to identify the risk factors...

Abstract Context Acromegaly is usually a sporadic disease, but familial cases occur. Mutations in the aryl hydrocarbon receptor‐interacting protein (AIP) gene are associated with familial pituitary adenoma predisposition. However, the pathogenicity of some AIP variants remains unclear and additional unknown genes may be involved. Objective To explore the phenotype and genotype of a large kindred carrying the p.R304Q AIP variant. Methods The family comprised 52 family members...

Background Stage III renal cell carcinoma (RCC) encompasses both lymph node–positive (pT1‐3N1M0) and lymph node–negative (pT3N0M0) disease. However, prior institutional studies have indicated that among patients with stage III disease, those with lymph node disease have worse oncologic outcomes and experience survival that is similar to that of patients with American Joint Committee on Cancer (AJCC) stage IV disease. The objective of the current study was to validate these findings using a large,...

Summary Fibroblast growth factor‐19 (FGF‐19) is a gut hormone which interacts with metabolism and is depleted in obesity. There is some indication that the hormone undergoes a resurgence following bariatric surgery (BS), an effect which may contribute to the beneficial outcomes of such procedures. This systematic review and meta‐analysis aims to synthesize the available literature on FGF‐19 levels before and after BS. MEDLINE, Scopus and Web of Science databases were searched, and the effect of...

Abstract Patient-derived orthotopic xenograft (PDOX) models have been verified as a useful method for studying human cancers in mice. Previous studies on the extent of metastases in these models have been limited by the necessity of welfare euthanasia (primary tumors reaching threshold size), at which point metastases may only be micrometers in diameter, few in number, and solely identified by step-sectioning of formalin-fixed paraffin-embedded tissue. These small micro-metastases...

Abstract The placebo (Latin “I will please”) effect commonly occurs in clinical trials. The psychological and physiological factors associated with patients’ expectations about a treatment’s positive and negative effects have yet to be well characterized, although a functional prefrontal cortex and intense bidirectional communication between the central nervous system and the immune system appear to be prerequisites for a placebo effect. The use of placebo raises certain ethical issues, especially...

ABSTRACT Food protein‐induced enterocolitis syndrome (FPIES) is a non‐IgE‐mediated food allergy (1). Acute FPIES is typical and characterized by repetitive and often incoercible emesis starting 1–4 h after ingestion of the culprit food (1). Severe forms may result in dehydration or hypovolemic shock (1). In the absence of biomarkers, the diagnosis of FPIES is based on clinical presentation (1). Symptoms improve after exclusion of the culprit foods and acute FPIES occurs at re‐exposure. FPIES generally...

Abstract Background Conventional type 1 dendritic cells (cDC1s) control antiviral and antitumor immunity by inducing antigen‐specific cytotoxic CD8+ T‐cell responses. Controversy exists whether cDC1s also control CD4+ T helper 2 (Th2) cell responses, since suppressive and activating roles have been reported. DC activation status, controlled by the transcription factor NF‐κB, might determine the precise outcome of Th‐cell differentiation upon encounter with cDC1s. To investigate the role of...

Examining consent for interventional research in potential deceased organ donors: a narrative review
Summary In the last decade, research in transplant medicine has focused on developing interventions in the management of the deceased organ donor to improve the quality and quantity of transplantable organs. Despite the promise of interventional donor research, there remain debates about the ethics of this research, specifically regarding gaining research consent. Here, we examine the concerns and ambiguities around consent for interventional donor research, which incorporate questions about who...

Variables associated with survival in patients with invasive bladder cancer with and without surgery
Summary We recorded the survival of 141 patients assessed for radical cystectomy, which included cardiopulmonary exercise testing. The median Kaplan‐Meier survival estimates were: 1540 days for the whole cohort; 2200 days after cystectomy scheduled (n = 108); and 843 days without surgery. The mortality hazard remained double that expected for a matched general population, but survival was better in patients scheduled for surgery than those who were not: the mortality hazard ratio (95%CI) after...
