Clinical practice guidelines for management of disseminated intravascular coagulation in Japan 2024. Part 3: solid cancers and vascular abnormalities.

This study discusses disseminated intravascular coagulation (DIC) associated with solid cancers and various vascular abnormalities, both of which generally exhibit chronic DIC patterns. Solid cancers are among the most significant underlying diseases that induce DIC. However, the severity, bleeding tendency, and progression of DIC vary considerably depending on the type and stage of the cancer, making generalization difficult.

Dual single‑nucleotide polymorphism biomarker combination for opioid selection to treat cancer pain.

We have been exploring biomarkers that could help physicians select the appropriate opioid for individualized treatment of cancer pain. Recently, we identified a single nucleotide polymorphism (SNP) of (rs17809012) as one such biomarker that was significantly associated with the analgesic effect of morphine. The current study measured the plasma concentrations of chemokines/cytokines in pre-treatment plasma samples of a total of 138 patients who were randomized to receive morphine (n=70) or oxycodone (n=68).

The relationship between long COVID, labor productivity, and socioeconomic losses in Japan: A cohort study.

Objectives: We examined shifts in labor productivity and their economic ramifications among adult patients with long COVID in Japan.

Methods: A total of 396 patients were categorized into three groups based on symptom progression: non-long COVID, long COVID recovered, and long COVID persistent. Patient-reported outcomes were assessed at three time intervals: 3, 6, and 12 months after COVID-19 diagnosis.

Clinical practice guidelines for management of disseminated intravascular coagulation in Japan 2024. Part 1: sepsis.

The Japanese Society on Thrombosis and Hemostasis (JSTH) published the first-ever disseminated intravascular coagulation (DIC) guidelines in 2009. Fifteen years later, the JSTH developed new guidelines covering DIC associated with various underlying conditions. These guidelines were developed in accordance with the GRADE system to determine the strength of the recommendations and certainty of the evidence.

Clinical practice guidelines for management of disseminated intravascular coagulation in Japan 2024. Part 2: hematologic malignancy.

Disseminated intravascular coagulation (DIC) associated with hematologic malignancies, particularly acute promyelocytic leukemia (APL), is characterized by marked fibrinolytic activation, which leads to severe bleeding complications. Therefore, appropriate diagnosis and management of DIC are crucial for preventing bleeding-related mortality. However, to date, no clinical guidelines have specifically addressed hematologic malignancy-associated DIC.

Predicting time to castration resistance with androgen-receptor signaling inhibitors in hormone-sensitive prostate cancer: data from ULTRA-Japan Consortium.

Background: Androgen-receptor signaling inhibitors (ARSIs) become the new standard of care for metastatic hormone-sensitive prostate cancer (mHSPC). It is unknown whether time to castration resistance (TTCR), when using the first-line ARSIs, offers predictive value in mHSPC. We sought to assess the clinical outcomes for mHSPC patients treated with first-line ARSIs focusing on the TTCR.

Effects of an online program about intimate and romantic relationships for people with mental disorders (AIRIKI): a study protocol for a randomized controlled trial.

Background: The concept of recovery has become internationally widespread. To promote personal recovery of individuals with mental disorders, it is important that they live life on their own terms. Many people with mental disorders wish to build intimate relationships and marry.

Introduction: EGFR tyrosine kinase inhibitors have been the standard treatment for patients with NSCLC who have sensitive mutations. This study revealed final analysis survival data, biomarkers, and resistance mechanisms of osimertinib plus bevacizumab or osimertinib monotherapy in previously untreated patients with advanced -positive nonsquamous NSCLC.

Methods: We previously reported the primary results of a randomized, open-label, phase 2 study comparing osimertinib plus bevacizumab with osimertinib monotherapy for this population.

Improved platelet separation performance from whole blood using an acoustic fluidics system.

This study investigated the effectiveness of acoustic separation for platelet analysis in patients with non-small-cell lung cancer (NSCLC), comparing it with traditional centrifugation methods. In total, 10 patients with NSCLC and 10 healthy volunteers provided peripheral blood samples, which were processed using either acoustic separation or centrifugation to isolate platelets. The study included whole transcriptome analysis of platelets, peripheral blood mononuclear cells, and tumor tissue samples, employing hierarchical clustering and Gene Ontology analysis to explore gene expression differences.

A machine learning-based method for feature reduction of methylation data for the classification of cancer tissue origin.

Background: Genome DNA methylation profiling is a promising yet costly method for cancer classification, involving substantial data. We developed an ensemble learning model to identify cancer types using methylation profiles from a limited number of CpG sites.

Methods: Analyzing methylation data from 890 samples across 10 cancer types from the TCGA database, we utilized ANOVA and Gain Ratio to select the most significant CpG sites, then employed Gradient Boosting to reduce these to just 100 sites.

Different characteristics of the tumor immune microenvironment among subtypes of salivary gland cancer.

Aim: Although immune checkpoint inhibitors (ICPi) for salivary gland cancer (SGC) have been investigated in clinical trials, details of the tumor immune microenvironment (TIME) remain unclear. This research aimed to elucidate the TIME of SGC and its relationship with tumor mutation burden (TMB) and to explore the rationale for the applicability of ICPi.

Materials And Methods: We selected five pathological types, namely adenoid cystic carcinoma (ACC); adenocarcinoma, not otherwise specified (ANOS); salivary duct carcinoma (SDC); and low/high-grade mucoepidermoid carcinoma (MEC).

A qualitative study of stressors faced by older stroke patients in a convalescent rehabilitation hospital.

This study aimed to explore the stressors experienced by older patients with stroke in convalescent rehabilitation wards in Japan. Semi-structured interviews were conducted with four stroke patients aged > 65 years who experienced a stroke for the first time in their lives. The interviews were analyzed using the Steps for Coding and Theorization method for qualitative data analysis.

Various Laparoscopic Techniques in Pelvic Organ Prolapse Surgery.

In the past, transvaginal surgery, native tissue restoration, or obliterative methods have been used in the majority of pelvic organ prolapse (POP) surgeries. Since laparoscopy has gained popularity, other procedures have been created to provide additional POP repair alternatives. Laparoscopic technique offers many advantages compared to open or transvaginal surgery when it comes to anatomical and surgical outcomes, recurrence rates, and patient's acceptance.

Revisiting the hormonal control of sexual dimorphism in chicken feathers.

Sexual dimorphism in plumage is widespread among avian species. In chickens, adult females exhibit countershading, characterized by dull-colored round feathers lacking fringe on the saddle, while adult males display vibrant plumage with deeply fringed bright feathers. This dimorphism is estrogen-dependent, and administering estrogen to males transforms their showy plumage into cryptic female-like plumage.

Exploring the relationship between ulcerative colitis, colorectal cancer, and prostate cancer.

Chronic systemic inflammation caused by diseases such as ulcerative colitis (UC) and Crohn's disease (CD) increases the risk of developing colorectal cancer (CRC). Recent evidence indicates that patients with UC are more susceptible to prostate cancer (PCa), and individuals with PCa may also be at a higher risk of developing CRC. However, these relationships are not well defined.

Two Distinct Characteristics of Immune Microenvironment in Human Hepatocellular Carcinoma with Wnt/β-Catenin Mutations.

Introduction: Immunotherapy is becoming a promising approach for unresectable-hepatocellular carcinoma (HCC); the anti-tumor response is affected by the tumor microenvironment (TME). Although Wnt/β-catenin mutations are reported to cause non-inflamed phenotype, their role on TME remains controversial. We aimed to clarify the heterogeneity of immunophenotype in HCC with Wnt/β-catenin mutations.

Introduction: The underlying risks of asymptomatic embolization during high-power short-duration (HPSD) ablation for atrial fibrillation remain unclear. We aimed to evaluate microembolic signals (MESs) during HPSD ablation with power settings of 50 and 90 W in comparison with those during cryoballoon (CB) ablation using a novel carotid ultrasound-Doppler system that classifies solid and air bubble signals using real-time monitoring.

Methods And Results: Forty-seven patients underwent HPSD ablation using radiofrequency (RF), and 13 underwent CB ablation.

C-Reactive Protein-Albumin Ratio Predicts Objective Response to Enfortumab Vedotin in Metastatic Urothelial Carcinoma.

Background: Enfortumab vedotin (EV), an antibody-drug conjugate that targets Nectin-4, is used for patients with metastatic urothelial carcinoma who have experienced progression on platinum-based chemotherapy and checkpoint inhibitors. Despite the widespread use of the drug, evidence remains scarce regarding clinical indicators that can predict the response to EV treatment.

Objective: We aimed to explore the predictive value of clinical indicators derived from peripheral blood tests for treatment responses to EV.

Significance of Prediction Models for Post-Hepatectomy Liver Failure Based on Type IV Collagen 7s Domain in Patients with Hepatocellular Carcinoma.

Previous studies have attempted to establish predictive models for post-hepatectomy liver failure (PHLF) in patients with hepatocellular carcinoma (HCC) undergoing liver resection. However, a versatile and useful predictive model for PHLF remains to be developed. Therefore, we aimed to develop predictive models for PHLF based on type IV collagen 7s domain (7s collagen) in patients with HCC.

Liquidus curve of a Lennard-Jones mixture.

The temperature below which the homogeneous liquid state of a mixture is not thermodynamically stable is called the liquidus temperature. This temperature varies with composition, and its composition dependence is represented by the liquidus curve. This curve provides fundamental reference points on the composition-temperature plane for characterizing the behavior of liquids, glasses, and crystals.

The Tumor Immune Microenvironment Is Associated With Recurrence in Early-Stage Lung Adenocarcinoma.

Introduction: Immune checkpoint inhibitors have recently been approved for the treatment of early-stage NSCLC in the perioperative setting on the basis of phase 3 trials. However, the characteristics of such patients who are susceptible to recurrence after adjuvant chemotherapy or who are likely to benefit from postoperative immunotherapy have remained unclear.

Methods: This biomarker study (WJOG12219LTR) was designed to evaluate cancer stem cell markers (CD44 and CD133), programmed death-ligand 1 (PD-L1) expression on tumor cells, CD8 expression on tumor-infiltrating lymphocytes, and tumor mutation burden in completely resected stage II to IIIA NSCLC with the use of archived DNA and tissue samples from the prospective WJOG4107 trial.
