Excitatory neuron-prone prion propagation and excitatory neuronal loss in prion-infected mice.

The accumulation of a disease-specific isoform of prion protein (PrP) and histopathological lesions, such as neuronal loss, are unevenly distributed in the brains of humans and animals affected with prion diseases. This distribution varies depending on the diseases and/or the combinations of prion strain and experimental animal. The brain region-dependent distribution of PrP and neuropathological lesions suggests a neuronal cell-type-dependent prion propagation and vulnerability to prion infection.

Sugar-binding profiles of the mesothelial glycocalyx in frozen tissues of mice revealed by lectin staining.

The mesothelium is a non-adhesive protective surface that lines the serosal cavities and organs within the body. The glycocalyx is a complex structure that coats the outer layer of the mesothelium. However, due to the limitations of conventional fixation techniques, studies on glycans are limited.

CONUT score as a predictor for anamorelin efficacy in patients with cancer cachexia receiving chemotherapy.

Background: Anamorelin is expected to improve cancer cachexia by increasing lean body mass (LBM) due to increased appetite and protein synthesis. However, the effect of anamorelin on cancer cachexia in real-world practice is unclear. The purpose of this study was to evaluate the efficacy and safety of anamorelin and to identify predictors of efficacy on treatment with anamorelin.

Evaluation of Steroid-Induced Osteoporosis Prevention Using Tracing Reports in Collaboration between Hospitals and Community Pharmacists.

Glucocorticoid-induced osteoporosis (GIOP) is a side effect of glucocorticoid (GC) treatment; however, despite established prevention guidelines in various countries, a gap persists between these guidelines and clinical practice. To address this gap, we implemented a collaborative intervention between hospitals and community pharmacists, aiming to assess its effectiveness. Pharmacists recommended to the prescribing doctor osteoporosis treatment for patients who did not undergo osteoporosis treatment with a fracture risk score of ≥3 via tracing reports (TRs), between 15 December 2021, and 21 January 2022.

Characterization of Shiga Toxin-producing Escherichia coli Isolated from Cattle Around Ulaanbaatar City, Mongolia.

Shiga toxin-producing Escherichia coli (STEC) are associated with severe infections including hemorrhagic colitis and hemolytic uremic syndrome in humans. Ruminants are known as reservoirs of STEC; however, no data are available on STEC in ruminants in Mongolia, where more than 5 million cattle and 25 million sheep are raised. To disclose the existence and characteristics of STEC in Mongolia, in this study, we isolated and characterized STEC from cattle in Mongolia.

The emerging emetogenicity of trifluridine/tipiracil (TAS‑102) from patient self-reporting: a multicenter, prospective, observational study.

Background: Trifluridine/tipiracil (TAS-102) is an oral anticancer drug with adequate efficacy in unresectable colorectal cancer, but frequently also induces chemotherapy-induced nausea and vomiting (CINV). To investigate the occurrence of CINV and antiemetic therapy in patients with colorectal cancer treated with TAS-102 (JASCC-CINV 2001).

Methods: We conducted a multicenter, prospective, observational study in patients with colorectal cancer who received TAS-102 without dose reduction for the first time.

Nafamostat mesylate decreases skin flap necrosis in a mouse model of type 2 diabetes by protecting the endothelial glycocalyx.

The success rate of flap tissue reconstruction has increased in recent years owing to advancements in microsurgical techniques. However, complications, such as necrosis, are still more prevalent in diabetic patients compared to non-diabetic individuals, presenting an ongoing challenge. To address this issue, many previous studies have examined vascular anastomoses dilation and stability, primarily concerning surgical techniques or drugs.

Proton Pump Inhibitors and Cyclin-Dependent Kinase 4/6 Inhibitors in Patients With Breast Cancer.

Background: Proton pump inhibitors (PPIs) reduce the bioavailability of several anticancer drugs. The impact of PPIs co-administered with cyclin-dependent kinase 4 and 6 inhibitors is controversial. We aimed to clarify whether the concomitant use of PPIs impacts palbociclib and abemaciclib effectiveness in breast cancer treatment.

Recombinant antithrombin attenuates acute kidney injury associated with rhabdomyolysis: an in vivo animal study.

Background: Rhabdomyolysis is characterized by the destruction and necrosis of skeletal muscle tissue, resulting in acute kidney injury (AKI). Recombinant antithrombin (rAT) has DNA repair and vascular endothelial-protection properties. Herein, we investigated whether rAT therapy has beneficial effects against rhabdomyolysis-induced AKI.

Endothelial Glycocalyx in the Peripheral Capillaries is Injured Under Oxaliplatin-Induced Neuropathy.

Oxaliplatin, a platinum-based anticancer drug, is associated with peripheral neuropathy (oxaliplatin-induced peripheral neuropathy, OIPN), which can lead to worsening of quality of life and treatment interruption. The endothelial glycocalyx, a fragile carbohydrate-rich layer covering the luminal surface of endothelial cells, acts as an endothelial gatekeeper and has been suggested to protect nerves, astrocytes, and other cells from toxins and substances released from the capillary vessels. Mechanisms underlying OIPN and the role of the glycocalyx remain unclear.

The role of pharmacists in multimodal cancer cachexia care.

Cancer cachexia is a complex syndrome, and multidisciplinary management has the potential to improve patient outcomes and efficiency of care. Multidisciplinary management consists primarily of exercise, nutrition, and pharmacotherapy. The pharmacist's role in cancer cachexia is to contribute to appropriate pharmacotherapy practices.

Prevention of vincristine-induced peripheral neuropathy by protecting the endothelial glycocalyx shedding.

Vincristine-induced peripheral neuropathy (VIPN) adversely affects the quality of life and treatment continuity of patients. The endothelial glycocalyx (eGCX) protects nerves from harmful substances released from the capillary vessels, but its role in peripheral neuropathy remains unclear. We investigated the impact of eGCX protection on VIPN.

Progressive multifocal leukoencephalopathy analyzed using the Japanese Adverse Drug Event Report database.

Background: Progressive multifocal leukoencephalopathy (PML) has been reported as the development of drugs with immunomodulatory properties, such as anticancer, immunosuppressive, and biological agents, has accelerated. To clarify an incidence profile of drug-associated PML in real-world clinical practice, we analyzed reported patients with PML using the Japanese Adverse Drug Event Report (JADER) database.

Methods: We analyzed PML reports extracted from the JADER database based on the preferred term of "progressive multifocal leukoencephalopathy" from between 2004 and 2021.

Prognostic impact of severe neutropenia in colorectal cancer patients treated with TAS-102 and bevacizumab, addressing immortal-time bias.

Background: Several studies have reported an association between severe neutropenia and long-term survival in patients treated with trifluridine-tipiracil (TAS-102). Because some of these studies failed to address immortality time bias, however, their findings should be interpreted with caution. Additionally, the association between severe neutropenia and survival in patients receiving TAS-102 in combination with bevacizumab (Bmab) remains unclear.

Efficacy and Safety of Oxaliplatin-based Regimens as First-line Chemotherapy in Elderly Patients With Metastatic Colorectal Cancer.

Background/aim: Metastatic colorectal cancer (mCRC) is mainly a disease of the elderly. The aim of this retrospective study was to investigate the efficacy and safety of oxaliplatin-based regimens as first-line chemotherapy in elderly patients with mCRC.

Patients And Methods: We recruited mCRC patients aged ≥75 years who were treated with oxaliplatin-based chemotherapy as first-line therapy from October 2011 to November 2020.

Comparison of the incidence of vancomycin-associated nephrotoxicity following the change from trough-guided dosing to AUC-guided doing using trough-only data.

Objectives: Although use of AUC-guided vancomycin dosing was recommended in the revised 2020 consensus guideline, collection of multiple vancomycin serum samples to calculate AUC may cause clinical complications. AUC calculated from trough-only data (one-point AUC-guided dosing) has not been sufficiently validated. The aim of the present study was to compare the incidence of nephrotoxicity following the change from trough-guided to one-point AUC-guided dosing.

Efficacy and safety of 5HT3RA, DEX, and NK1RA for the prevention of FOLFIRINOX-induced nausea and vomiting in patients with pancreatic cancer: a retrospective cohort study.

Purpose: Modified FOLFIRINOX (mFFX), a standard chemotherapy regimen for advanced pancreatic cancer (APC), is expected to be associated with a higher risk of chemotherapy-induced nausea and vomiting (CINV). Herein, we conducted a retrospective cohort study to evaluate the efficacy and safety of a three-drug combination of 5-hydroxytryptamine-3 receptor antagonists (5HT3RA), dexamethasone (DEX), and neurokinin 1 receptor antagonists (NK1RA) for the prevention of CINV during mFFX therapy.

Methods: This study enrolled patients with APC who received mFFX as initial therapy with a combination of 5HT3RA, DEX, and NK1RA as antiemetic prophylaxis.

Investigation of the relationship between intradialytic hypotension during hemodialysis and serum syndecan-1 concentration.

Intradialytic hypotension and arrhythmias are complications of hemodialysis. They are associated with decreased intravascular volume due to reduced ultrafiltration volume, cardiac function, and arterial tone. The vascular endothelial glycocalyx, which exists on the surface of healthy vascular endothelial cells and maintains vascular permeability, has been suggested to be impaired by hemodialysis.

Doublet or Triplet Antiemetic Prophylaxis for Nausea and Vomiting Induced by Trastuzumab Deruxtecan: an Open-Label, Randomized, and Multicenter Exploratory Phase 2 Study.

Trastuzumab deruxtecan is classified as an anticancer agent that poses a moderate emetic risk in the international guidelines for antiemetic therapy. The guidelines recommend emesis prophylaxis using a two-drug combination therapy comprising a 5-hydroxytryptamine-3 receptor antagonist (5-HT3RA) and dexamethasone (DEX). However, the high incidence of nausea and vomiting associated with trastuzumab deruxtecan is problematic.

[Reduction in Patient Waiting Times in Pharmacies by a Protocol to Minimize Inquiries to Doctors under an Agreement between a Hospital and Community Pharmacies].

Cooperative care between hospitals and community pharmacies is important to safe and effective pharmacotherapy for outpatients. We developed a protocol comprising three agreements about alternative drugs and dosing schedules with the aim of minimizing inquiries about prescriptions to doctors. The protocol was implemented under an agreement between core hospitals in Gifu City and community pharmacy members of the Gifu City Pharmaceutical Association from October 2019.
