The polymyxin-B direct hemoperfusion OPTimal Initiation timing with Catecholamine PMX-OPTIC study: A multicenter retrospective observational study.

Background: Polymyxin-B direct hemoperfusion (PMX-DHP) is an endotoxin adsorption column-based blood purification therapy. Since one of the most potent effects of PMX-DHP is blood pressure elevations, it may be the most effective when it is introduced at the time when the need for vasopressors is the greatest, which, in turn, may reduce mortality.

Methods: A multicenter retrospective study was conducted at 24 ICUs in Japan.

Change in Liver Function in Durvalumab Plus Tremelimumab Treatment for Unresectable Hepatocellular Carcinoma.

Background/aim: Maintaining liver function throughout the treatment of hepatocellular carcinoma (HCC) is crucial, yet the impact of durvalumab plus tremelimumab (DT) treatment on liver function is not well understood. This multicenter study aimed to examine the changes in liver function during DT treatment.

Patients And Methods: This nationwide multicenter study included 80 patients who received DT treatment for unresectable HCC.

Control of germinal center B cell survival and IgE production by an adaptor molecule containing PH and SH2 domains, Aps/Sh2b2.

The germinal centers (GCs) are structure found within secondary lymphoid organs and are important for the antibody-producing response against foreign antigens. In GCs, antigen-specific B cells proliferate intensely, inducing immunoglobulin class switching. Recent studies have shown that GCs are also an important site for class switching to IgE, which is implicated in allergy.

Tonic TCR and IL-1β signaling mediate phenotypic alterations of naive CD4 T cells.

Inert naive CD4 T (T) cells differentiate into functional T helper (Th) or regulatory T (Treg) cell subsets upon encountering antigens, mediating properly directed immune responses. Although all T cells can differentiate into any of the Th and Treg cell subsets, heterogeneity exists among T cells. By constructing reporter mice to detect ongoing T cell receptor (TCR) signaling, we identify that interleukin (IL)-1β signaling affects T cell characteristics, independent of tonic TCR signaling, which also alters T cell phenotypes.

Composition of fatty acids in a high-fat diet affects adipose tissue inflammation by inducing calreticulin on adipocytes and activating group 1 innate lymphoid cells.

Obesity-induced adipose tissue inflammation plays a critical role in the development of metabolic diseases. For example, NK1.1 group 1 innate lymphoid cells (G1-ILCs) in adipose tissues are activated in the early stages of inflammation in response to a high-fat diet (HFD).

Defining the Standard of the Terminology of the Mechanical Ventilation Data in Japan.

To effectively use data from intensive care unit patient information systems at multiple hospitals, it is necessary to standardize the data into a well-ordered form. However, terms often vary between devices. We designed a mechanical ventilation concept model and applied data to that model using existing tools and expert opinions.

Creatinine Reduction Ratio Is a Prognostic Factor for Acute Kidney Injury following Cardiac Surgery with Cardiopulmonary Bypass: A Single-Center Retrospective Cohort Study.

Acute kidney injury (AKI) after cardiac surgery is a common complication that can lead to death. We previously reported that the creatinine reduction ratio (CRR) serves as a useful prognostic factor for AKI. The primary objective of this study was to determine the predictors of AKI after surgery.

A case of difficult-to-diagnose hepatic reactive lymphoid hyperplasia finally diagnosed by using PCR analysis of IgH-gene rearrangements: a case report.

Reactive lymphoid hyperplasia (RLH) of the liver is extremely rare. Despite advancements in diagnostic imaging technology, it is still difficult to distinguish from hepatocellular carcinoma (HCC). Herein, we present a case of hepatic RLH mimicking HCC that was postoperatively diagnosed using several imaging modalities.

[A case of retrograde intussusception due to transverse colon cancer detected by abdominal ultrasonography].

A 78-year-old female patient presented to our hospital with abdominal pain and melena. Abdominal ultrasonography detected a multiple concentric ring sign and retrograde invagination mass near the hepatic flexure. Colonoscopy revealed a 40-mm diameter type 1 tumor in the transverse colon near the splenic flexure, and the biopsy specimen demonstrated a well-differentiated adenocarcinoma.

Outcomes of Patients with Child-Pugh B and Unresectable Hepatocellular Carcinoma Undergoing First-Line Systemic Treatment with Sorafenib, Lenvatinib, or Atezolizumab Plus Bevacizumab.

Introduction: Systemic therapy is recommended for patients with Child-Pugh A in hepatocellular carcinoma (HCC). We analyzed the outcomes of a cohort of patients with HCC who received either sorafenib (Sor), lenvatinib (Len) or atezolizumab plus bevacizumab (Atezo + Bev) as first-line systemic therapy for HCC, with the aim of identifying prognostic factors for survival.

Methods: A total of 825 patients with advanced HCC and Child-Pugh A or B received either Sor, Len or Atezo + Bev as first-line systemic therapy.

Impact of Persistent Inflammation, Immunosuppression, and Catabolism Syndrome during Intensive Care Admission on Each Post-Intensive Care Syndrome Component in a PICS Clinic.

Background: Persistent inflammation, immunosuppression, and catabolism syndrome (PIICS) is known as a prolonged immunodeficiency that occurs after severe infection. Few studies have demonstrated a direct relationship between PIICS and physical dysfunction in post-intensive care syndrome (PICS). We herein investigated how each component of PICS was affected by the diagnosis of PIICS during hospitalization and examined the relationship between PIICS and PICS using PICS assessments performed at the Hitachi General Hospital PICS Clinic.

Stomach position evaluated using computed tomography is related to successful post-pyloric enteral feeding tube placement in critically ill patients: a retrospective observational study.

Background: Post-pyloric enteral feeding reduces respiratory complications and shortens the duration of mechanical ventilation. Blind placement of post-pyloric enteral feeding tubes (EFT) in patients with critical illnesses is often the first-line method because endoscopy or fluoroscopy cannot be easily performed at bedside; however, difficult placements regularly occur. We reported an association between the stomach position caudal to spinal level L1-L2, evaluated by abdominal radiographs after placement, and difficult placement; however, this method could not indicate difficulty before EFT placement.

Effects on survival of the adverse event of atezolizumab plus bevacizumab for hepatocellular carcinoma: a multicenter study by the Japan Red Cross Liver Study Group.

This study aimed to describe the real-world efficacy and safety of the combination therapy of atezolizumab and bevacizumab (Atezo/Bev) for unresectable hepatocellular carcinoma (HCC). This retrospective analysis of a multicenter registry cohort included 268 patients treated with Atezo/Bev. The incidence of adverse events (AE) and its impact on overall survival (OS) and progression-free survival (PFS) were analyzed.

Cost-effectiveness analysis of intradiscal condoliase injection vs. surgical or conservative treatment for lumbar disc herniation.

Aims: This study aimed to analyze the cost-effectiveness of intradiscal condoliase injection compared to surgical or conservative treatment for patients with lumbar disc herniation (LDH) who are refractory to conservative treatment.

Methods: We performed the following cost-effectiveness analyses: (I) condoliase followed by open surgery (for non-responders to condoliase) vs. open surgery from the beginning, (II) condoliase followed by endoscopic surgery (for non-responders to condoliase) vs.

Mycobacterial protein PE_PGRS30 induces macrophage apoptosis through prohibitin 2 mitochondrial function interference.

PE_PGRS30 belongs to the PE_PGRS protein family and is characterized by a conserved Pro-Glu (PE) domain and a typically polymorphic GC-rich sequence (PGRS) domain. PE_PGRS30 is a virulence factor of that induces macrophage cell death. We found that RAW264.
