The significance of therapeutic drug monitoring in detecting low medication adherence in patients with cancer: A case study of cabozantinib.

Maintaining good medication adherence is important for providing desirable outcomes from medication therapy. We showed that therapeutic drug monitoring (TDM) contributed to the identification of low medication adherence to cabozantinib in a patient with cancer. We present an educational case to assist with understanding TDM in a patient with cancer.

Preliminary Investigation of a Rapid and Feasible Therapeutic Drug Monitoring Method for the Real-Time Estimation of Blood Pazopanib Concentrations.

Pazopanib is a multi-kinase inhibitor used to treat advanced/metastatic renal cell carcinoma and advanced soft tissue tumors; however, side effects such as diarrhea and hypertension have been reported, and dosage adjustment based on drug concentration in the blood is necessary. However, measuring pazopanib concentrations in blood using the existing methods is time-consuming; and current dosage adjustments are made using the results of blood samples taken at the patient's previous hospital visit (approximately a month prior). If the concentration of pazopanib could be measured during the waiting period for a doctor's examination at the hospital (in approximately 30 min), the dosage could be adjusted according to the patient's condition on that day.

Clinical Features and Treatment of Patients Infected With SARS-CoV-2 Omicron Variant While Hospitalized Due to Stroke: A Single Center Study in Japan.

Background And Objective: In December 2019, COVID-19 spread rapidly across the globe. Throughout the pandemic, SARS-CoV-2 repeatedly mutated, transitioning from the alpha variant to the omicron variant. The severity and mortality of COVID-19 have been linked to age, sex, and the presence of underlying diseases (respiratory, cerebrovascular, cardiovascular, metabolic, and immune diseases, as well as cancer).

OPTIMAL PLASMA CONCENTRATION OF THROMBOMODULIN ALFA TO TREAT SEPSIS-INDUCED DISSEMINATED INTRAVASCULAR COAGULATION.

Thrombomodulin alfa (TM alfa) has been shown effective for treatment of disseminated intravascular coagulation (DIC) associated with sepsis, although the optimal therapeutic plasma concentration has not been clarified. In the present study, the plasma trough concentration of TM alfa in septic patients with DIC was determined, then the cutoff value for that concentration showing influence on treatment outcome was calculated using a receiver operating characteristic curve. With a cutoff value of 1,010, the area under the curve of the receiver operating characteristic was 0.

Role of SOCS and VHL Proteins in Neuronal Differentiation and Development.

The basic helix-loop-helix factors play a central role in neuronal differentiation and nervous system development, which involve the Notch and signal transducer and activator of transcription (STAT)/small mother against decapentaplegic signaling pathways. Neural stem cells differentiate into three nervous system lineages, and the suppressor of cytokine signaling (SOCS) and von Hippel-Lindau (VHL) proteins are involved in this neuronal differentiation. The SOCS and VHL proteins both contain homologous structures comprising the BC-box motif.

Real-time intelligent classification of COVID-19 and thrombosis via massive image-based analysis of platelet aggregates.

Microvascular thrombosis is a typical symptom of COVID-19 and shows similarities to thrombosis. Using a microfluidic imaging flow cytometer, we measured the blood of 181 COVID-19 samples and 101 non-COVID-19 thrombosis samples, resulting in a total of 6.3 million bright-field images.

SOCS7-Derived BC-Box Motif Peptide Mediated Cholinergic Differentiation of Human Adipose-Derived Mesenchymal Stem Cells.

Adipose-derived mesenchymal stem cells (ADMSCs) are a type of pluripotent somatic stem cells that differentiate into various cell types such as osteoblast, chondrocyte, and neuronal cells. ADMSCs as donor cells are used to produce regenerative medicines at hospitals and clinics. However, it has not been reported that ADMSCs were differentiated to a specific type of neuron with a peptide.

Quantitative determination of plasma cabozantinib concentration using HPLC-UV and its application to patients with renal cell carcinoma.

Cabozantinib is an oral small-molecule tyrosine kinase inhibitor that has become a standard of care for advanced renal cell carcinoma (RCC). However, cabozantinib is associated with a high rate of adverse events. Therefore, individualised cabozantinib administration and monitoring could help maximise its therapeutic efficacy and avoid serious adverse events.

Long-term effects of Pfizer-BioNTech COVID-19 vaccinations on platelets.

There is a global concern about the safety of COVID-19 vaccines associated with platelet function. However, their long-term effects on overall platelet activity remain poorly understood. Here we address this problem by image-based single-cell profiling and temporal monitoring of circulating platelet aggregates in the blood of healthy human subjects, before and after they received multiple Pfizer-BioNTech (BNT162b2) vaccine doses over a time span of nearly 1 year.

Usefulness of criteria for intraoperative Management of Postoperative Nausea and Vomiting.

Background: Postoperative nausea and vomiting (PONV) delays postoperative recovery, prolongs hospital stays, and hinders patients' return to society, thus making it a major cause of increased healthcare costs. It is also the most troubling postoperative complication in female patients undergoing surgery. However, in Japan, guidelines for the management of PONV have not been established, and the management protocol for PONV is left to each institution and anesthesiologist.

Anaplastic myxopapillary ependymoma: A case report and review of literature.

Background: Myxopapillary ependymoma (MPE) is a pathological grade I tumor that arises in the filum terminale. MPE with anaplastic features is extremely rare, and only 5 cases have shown malignancy at the time of recurrence.

Case Summary: The patient (a 46-year-old woman) had undergone a MPE operation 30 years ago.

Massive image-based single-cell profiling reveals high levels of circulating platelet aggregates in patients with COVID-19.

A characteristic clinical feature of COVID-19 is the frequent incidence of microvascular thrombosis. In fact, COVID-19 autopsy reports have shown widespread thrombotic microangiopathy characterized by extensive diffuse microthrombi within peripheral capillaries and arterioles in lungs, hearts, and other organs, resulting in multiorgan failure. However, the underlying process of COVID-19-associated microvascular thrombosis remains elusive due to the lack of tools to statistically examine platelet aggregation (i.

Efficacy of Supraclavicular Scalenotomy Followed by External Neurolysis without Rib Resection for Post-traumatic Neurogenic Thoracic Outlet Syndrome.

Most patients with neurogenic thoracic outlet syndrome (NTOS) have a history of trauma. Scar tissue formation within the scalene muscle and around the nerves after injury cause arm and hand symptoms. We report that supraclavicular scalenotomy followed by external neurolysis without rib resection is very effective as the surgical treatment.

BC-Box Motif in SOCS6 Induces Differentiation of Epidermal Stem Cells into GABAnergic Neurons.

The BC-box motif in suppressor of cytokine signaling 6 (SOCS6) promotes the neuronal differentiation of somatic stem cells, including epidermal stem cells. SOCS6 protein belongs to the group of SOCS proteins and inhibits cytokine signaling. Here we showed that epidermal stem cells were induced to differentiate into GABAnergic neurons by the intracellular delivery of a peptide composed of the amino-acid sequences encoded by the BC-box motif in SOCS6 protein.

Role of VHL-JAK-STAT signaling pathway in central nervous system hemangioblastoma associated with von Hippel-Lindau disease.

Introduction: Central nervous system hemangioblastoma is a benign tumor associated with or without von Hippel-Lindau (VHL) disease which is an autosomal dominant hereditary disease that results from a germline mutation in the VHL gene. A main axis of signaling pathways in central nervous system hemangioblastoma is VHL-HIF signaling pathway. Here, we propose an alternative VHL-JAK-STAT signaling pathway in hemangioblastoma and discuss the role.

Predictors of the Response to an Epidural Blood Patch in Patients with Spinal Leakage of Cerebrospinal Fluid.

Background And Purpose: An epidural blood patch (EBP) is a highly effective therapy for spinal cerebrospinal fluid (CSF) leakage. However, the factors predicting the response to an EBP have not been fully elucidated. The aim of this study was to elucidate factors predicting the response to an EBP.

Therapeutic and Adverse Effects of Thrombomodulin Alfa to Treat Sepsis-Induced Disseminated Intravascular Coagulation.

In the treatment of disseminated intravascular coagulation (DIC), which is a complication of underlying diseases such as infections and malignant tumors, effective plasma concentrations of thrombomodulin (TM) alfa range from 300 to 900 ng/mL; however, appropriate concentrations when treating sepsis-induced DIC are unknown. Thus, our aim was to determine the relationship between plasma concentrations of TM alfa and its therapeutic effects, and hemorrhagic adverse events. First, we calculated the plasma trough concentrations of TM alfa in septic DIC patients.

Simple, stable, compact implementation of frequency-division-multiplexed microscopy by inline interferometry.

Frequency-division-multiplexed (FDM) imaging is a powerful method for high-speed imaging that surpasses the speed limit of conventional imaging constrained by the frame rate of image sensors. However, its complexity, instability, and bulkiness deriving from the implementation with a Mach-Zehnder interferometer hamper its practical applications. Here we demonstrate a simple, stable, and compact implementation of FDM imaging by inline interferometry that makes the method readily available to practical situations.

VHL-Associated Optic Nerve Hemangioblastoma Treated with Stereotactic Radiosurgery.

Central nervous system hemangioblastomas are generally restricted to the cerebellum, spinal cord, and brainstem. Supratentorial hemangioblastomas are uncommon, and optic nerve hemangioblastomas are extremely rare, with fewer than 25 reports including this case. In this report, we present the case of a 36-year-old woman with von Hippel-Lindau (VHL) disease who presented with progressive diminution of vision in the left eye due to a retrobulbar optic nerve hemangioblastoma.

BC-Box Motif-Mediated Neuronal Differentiation of Somatic Stem Cells.

Von Hippel-Lindau tumor suppressor protein (pVHL) functions to induce neuronal differentiation of neural stem/progenitor cells (NSCs) and skin-derived precursors (SKPs). Here we identified a neuronal differentiation domain (NDD) in pVHL. Neuronal differentiation of SKPs was induced by intracellular delivery of a peptide composed of the amino-acid sequences encoded by the NDD.
