Fukushima Outpatient Pharmacotherapy Model for Breast Cancer.

The Fukushima Model of Outpatient Pharmacotherapy for Breast Cancer was developed to improve the pharmacological treatment of patients with breast cancer in the vast region of Fukushima Prefecture. This model addresses the challenges posed by the area's lower-than-average density of breast cancer specialists. In the core medical institutions of the prefecture's most populous municipalities, we introduced a telephone consultation service managed by pharmacists at local dispensing pharmacies.

Increasing trends of pharmaceutical payments to breast cancer specialists in Japan: A retrospective study from 2016 to 2019.

Introduction: The introduction of new drugs often leads to aggressive promotion and potential financial conflicts of interest, which may bias treatment decisions and potentially harm patients. The breast cancer therapeutics market is rapidly evolving globally, and Japan is no exception. This study aimed to analyze trends in pharmaceutical payments to breast cancer specialists in Japan from 2016 to 2019, focusing on company-level data, relationships with new drug introductions, and individual specialist payment patterns.

How should medical society face patient feedback in online review platforms?

In the medical field, the importance of online reviews is escalating. However, the complexity of responding to these reviews is profound, as such anonymous critiques may encompass not only emotionally distressing content but also potentially malicious criticisms directed at healthcare professionals. While recognizing the vital role of patient feedback, there exists a necessity for a collective approach to managing online commentary.

Application to Quantify Ulcer Areas and Track Their Progress.

Chronic ulcer treatments, such as those for diabetic foot ulcers and pressure sores, require prolonged treatment periods. Availability of effective objective indicators to determine treatment method efficacy is limited. Ulcer area is the agreed-upon indicator for ulcer healing because it contracts and/or undergoes epithelialization as healing occurs.

Two-Year-Span Breast Cancer Screening Uptake in Japan after the COVID-19 Pandemic and Its Association with the COVID-19 Vaccination.

There is limited information on whether the COVID-19 pandemic was associated with decreased breast cancer screening uptake and if COVID-19 vaccination was associated with an increase in screening uptake. Our study explored the uptake of breast cancer screening in Japan after the COVID-19 pandemic and assessed its association with the COVID-19 vaccination. We analyzed data from the Japan COVID-19 and Society Internet Survey (JACSIS), a web-based prospective cohort survey, and we included 6110 women without cancer history who were aged 40 to 74 years that participated in the 2012 and 2022 surveys.

Synthesis of fulgidic acid and the two possible stereoisomers of chaenomic acid D.

We synthesized fulgidic acid and the proposed structure for chaenomic acid D. The core part of the two natural products was constructed stereoselectively by the addition of acetic acid to the α,β-unsaturated epoxy alcohol in the presence of a palladium catalyst. Subsequently, the two natural products were synthesized from the intermediate in a few steps.

Clinical Significance of ABCG2/BCRP Quantified by Fluorescent Nanoparticles in Breast Cancer Patients Undergoing Neoadjuvant Chemotherapy.

Breast cancer resistance protein (BCRP), also known as ATP-binding cassette transporter G2 (ABCG2), is associated with chemotherapy resistance. BCRP is also implicated in breast cancer stem cells, and is reported as a poor prognostic factor. However, the relationship of BCRP levels in breast cancer tissues with chemotherapy resistance and prognosis has not been clarified.

Specification of skeletal muscle fiber-type is determined by the calcineurin/NFATc1 signaling pathway during muscle regeneration.

Skeletal muscle fiber type specification is changeable during muscle regeneration following cardiotoxin (CTX) injection; however, the mechanism of muscle fiber shift in regenerating muscle fibers remains unclear. Furthermore, it is unclear as to which factors determine skeletal muscle fiber types in regenerating muscle fibers. Previous studies showed that CTX-induced muscle damage resulted in a temporary hypoxic condition, indicating that hypoxia-inducible factor (HIF)-1α may be involved in muscle fiber type transition.

BRCA1 transports the DNA damage signal for CDDP-induced centrosome amplification through the centrosomal Aurora A.

Breast cancer gene 1 (BRCA1) plays roles in DNA repair and centrosome regulation and is involved in DNA damage-induced centrosome amplification (DDICA). Here, the centrosomal localization of BRCA1 and the kinases involved in centrosome duplication were analyzed in each cell cycle phase after treatment with DNA crosslinker cisplatin (CDDP). CDDP treatment increased the centrosomal localization of BRCA1 in early S-G2 phase.

Soluble interleukin-2 receptor as a predictive and prognostic marker for patients with familial breast cancer.

The incidence of breast cancer increases annually, and it has become common within families of breast cancer patients. Interleukin-2 activates cytotoxic T lymphocytes, which are important for cancer immunity. To identify markers of increased familial breast cancer risk, soluble interleukin-2 receptor levels and immunologic factors were investigated in familial breast cancer and non-familial breast cancer patients.

A case of lipoma, calcification, and brain malformations in the midline of the skull.

Few cases of pericallosal lipoma with several other lesions, including specific forms of calcification and brain malformations, have been reported. We present the case of an asymptomatic 83-year-old man with a pericallosallipoma with peculiar symmetrical morphology in the midline of the skull. We posit that the lesions began forming in the very early embryonic period and were closely associated with the cranial neural crest cells.

Ingestion of Okinawa Island Vegetables Increases IgA Levels and Prevents the Spread of Influenza RNA Viruses.

Background: It has been hypothesized that flavonoid ingestion stimulates immunity, promotes health, and prevents human illness. The aim of this analysis was to evaluate the association of the levels of immunoglobulin A (IgA) with the prevention of influenza infections and with the polyphenols contained in Okinawan vegetables.

Methods: IgA, immunoglobulin G (IgG), immunoglobulin M (IgM), and soluble interleukin-2 receptor (sIL-2R) levels were measured in 44 outpatients who regularly ingested vegetables grown on Okinawa Island (200-300 g/day for ≥ 300 days/year) with no history of influenza infection and in 73 patients who ingested the vegetables irregularly or not at all with a history of influenza infection.

The anti-angiogenic agent lenvatinib induces tumor vessel normalization and enhances radiosensitivity in hepatocellular tumors.

The evaluation of angiogenesis inhibitors requires the analysis of the precise structure and function of tumor vessels. The anti-angiogenic agents lenvatinib and sorafenib are multi-target tyrosine kinase inhibitors that have been approved for the treatment of hepatocellular carcinoma (HCC). However, the different effects on tumor vasculature between lenvatinib and sorafenib are not well understood.

Development of X-ray contrast agents using single nanometer-sized gold nanoparticles and lactoferrin complex and their application in vascular imaging.

The technology to accurately image the morphology of tumor vessels with X-ray contrast agents is important to clarify mechanisms underlying tumor progression and evaluate the efficacy of chemotherapy. However, in clinical practice, iodine-based contrast agents present problems such as short blood retention owing to a high clearance ability and insufficient X-ray absorption capacity when compared with other high atomic number elements. To resolve these issues, gold nanoparticles (AuNPs), with a high atomic number, have attracted a great deal of attention as contrast agents for angiography, and have been employed in small animal models.

[Supporting Technology for Development of Antibody Drug and Diagnostic Method to Predict Response to the Drug, by Using Fluorescence Imaging].

Fluorescence imaging is a very useful method for visualizing molecules and cells, but when tissues are measured", decrease in resolution due to increased scattering and absorption of light in proportion to tissue thickness (problem 1)" and "decrease in signal to noise(S/N)ratio of positive signal due to tissue autofluorescence(problem 2)"are problems to be solved. In this paper, to develop a technology to improve the analysis accuracy of drug efficacy mechanisms in preclinical trial of drug discovery, we performed development of a supporting technology for drug discovery of antibody drug conjugates by imaging living tumor tissues, while solving problem 1. This technology is expected to lead to an improvement in the success rate of clinical trials.
