Molecular epidemiology and clinical characterization of carbapenemase-producing Enterobacter spp. from an international cohort.

Background: Despite the global public health threat posed by carbapenem-resistant Enterobacter spp., clinical and molecular epidemiological studies on international isolates remain scarce. Historically, the taxonomy of Enterobacter has been challenging, limiting our understanding of the clinical characteristics and outcomes of carbapenemase-producing Enterobacter spp.

Visualizing risk modification of hypertensive disorders of pregnancy: development and validation of prediction model for personalized interpregnancy weight management.

The growing recognition of the importance of interpregnancy weight management in reducing hypertensive disorders of pregnancy (HDP) underscores the importance of effective preventive strategies. However, developing effective systems remains a challenge. We aimed to bridge this gap by constructing a prediction model.

Primary large B-cell lymphoma of the central nervous system: A reappraisal of CD5-positive cases based on clinical, pathological, and molecular evaluation.

CD5 expression is seen in 5%-10% of de novo diffuse large B-cell lymphomas (DLBCLs). Primary large B-cell lymphoma of the central nervous system (PCNS-LBCL) also exhibits CD5 expression in a minority of cases, however, clinicopathological and molecular features remain largely unclarified. Here we present the clinical, molecular, and pathological features of 11 CD5-positive () PCNS-LBCL cases, occupying 6.

Impact of CT-angiography derived plaque characteristics on cardiac events in patients with a negative invasive fractional flow reserve.

Background: Fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) for chronic coronary syndromes (CCS) improves outcomes compared with angiography-guided PCI, however cardiac events still occur during long-term follow-up of FFR-negative patients. In the PREVENT study preventive PCI reduced cardiac-events in lesions which were FFR-negative (FFR > 0.80) and had intracoronary imaging defined vulnerable plaque.

SUSD2 cancer-associated fibroblasts in gastric cancer mediate the effect of immunosuppression and predict overall survival and the effectiveness of neoadjuvant immunotherapy.

Background: The expression patterns and functions of Sushi Domain Containing 2 (SUSD2) differ among various malignancies. This research aims to investigate the expression of SUSD2 and the role of the SUSD2 cancer-associated fibroblasts (CAFs) for immunotherapy in gastric cancer.

Methods: The expression of SUSD2 and specific markers (CD4, CD8, PD-1, TIGIT, TIM-3 and CD163) was determined using immunohistochemistry and multiplex immunofluorescence (mIHC) on paraffin sections.

Effects of the COVID-19 pandemic on surgical treatment for thoracic malignant tumor cases in Japan: a national clinical database analysis.

Objective: Surgical care has been significantly affected by the COVID-19 pandemic. This study was conducted to evaluate the effects of the pandemic on lung cancer and mediastinal tumor surgery.

Methods: Changes in the number of surgical procedures for lung cancer and mediastinal tumors were analyzed using the National Clinical Database of Japan.

Relationship Between Psychological Stress Scores and Urinary 5-HT Levels Over Time Under Psychological Stress.

Background: Biomarkers for psychological stress have been examined and the "gut-microbiota-brain axis" is currently attracting attention. An intervention study reported improvements in both the intestinal environment and psychological stress. However, the relationship between psychological stress scores and urinary 5-hydroxytryptamine (u-5-HT), produced by enterochromaffin cells in the intestinal tract, has not yet been investigated over time in healthy subjects under psychological stress.

Assessment of factors affecting anterior chamber depth from data obtained from health checkup participants in Japan.

Measurement of anterior chamber depth (ACD), an important marker for the screening of primary angle-closure glaucoma, requires biometry, which is not readily used. This study assessed the relationship between ACD and health check-up data findings from participants with good corrected visual acuity in Japan. Participants underwent ophthalmic, anthropometric, and hematological assessments.

Development of the Japanese Anticholinergic Risk Scale: English translation of the Japanese article.

Background: Anticholinergic burden, reflecting the cumulative impact of medications with anticholinergic properties, significantly predicts adverse drug reactions and geriatric syndromes in older adults. Although anticholinergic risk scales (ARS) have been developed and validated in various countries, none have been tailored specifically for Japan. The Japanese Anticholinergic Risk Scale (JARS) was developed to adapt the existing ARS frameworks to the Japanese context, considering unique medication profiles and cultural factors.

Assessment of mumps virus-specific antibodies: Comparison of three different enzyme immunoassays and neutralization test.

Introduction: We evaluated the application of a newly improved enzyme immunoassay (EIA) kit, Mumps IgG Seiken®, by comparing antibody responses to different EIA kits, and neutralization tests (NTs), using clinical samples.

Methods: Serum samples were collected before and 4-6 weeks after vaccination from 128 children who had no history of mumps or mumps vaccination. Using three different EIA kits, Mumps IgG Seiken®, a commercial kit from Enzygnost®, and an in-house kit, mumps-specific IgG antibodies were measured.

Prognostic value of combining cardiac myosin-binding protein C and N-terminal pro-B-type natriuretic peptide in patients without acute coronary syndrome treated at medical cardiac intensive care units.

We investigated the prognostic value of cardiac myosin-binding protein C (cMyC), a novel cardiospecific marker, both independently and in combination with N-terminal pro-B-type natriuretic peptide (NT-proBNP), for predicting 6-month all-cause mortality in patients without acute coronary syndrome (ACS) treated at medical (nonsurgical) cardiac intensive care units (CICUs). Admission levels of cMyC, high-sensitivity cardiac troponin T (hs-cTnT), and NT-proBNP were measured in 1032 consecutive patients (mean age; 70 years) without ACS hospitalized acutely in medical CICUs for the treatment of cardiovascular disease. Serum cMyC was closely correlated with hs-cTnT and moderately with NT-proBNP (r = 0.

The appearance of scalp high-frequency oscillations is associated with poor seizure control in pediatric epilepsy patients.

Objective: Epilepsy treatment with anti-seizure medications (ASMs) is based on careful assessment of the balance between the likelihood of further seizures and the risk of side effects of treatment. However, there is currently no established biomarker to ascertain seizure control status with ASMs. High-frequency oscillations (HFOs), transient bursts of EEG activity with frequencies beyond 80 Hz, are a new and promising noninvasive epilepsy biomarker.

CCR4+Tfh2 cells specifically produce IL-4 driving the pathological reaction in IgG4-related disease.

Objectives: Human T follicular helper (Tfh) cells are classified into three subsets: Tfh1, Tfh2, and Tfh17 cells. Among them,Tfh2 cells are defined as CXCR3-negative and CCR6-negative, and may contain diverse cell populations. We examined whether CCR4 serves as a marker for identifying Tfh2 cells that produce interleukin (IL)-4 and its involvement in IgG4-related disease (IgG4-RD).

CD11b deficiency attenuates the ischemia/reperfusion-induced AKI-to-CKD process by regulating macrophage polarization.

Severe acute kidney injury (AKI) is a risk factor for the future development of chronic kidney disease (CKD), and macrophages are an essential cell group implicated in injury, repair, and fibrosis during this progress. However, the underlying mechanism of how macrophages participate in the development of the disease is largely unclear. CD11b (Integrin α) is highly expressed in monocytes/macrophages and has been verified to mediate broad functions.

Differential vasoproliferative traits of strains associated with autotransporter BafA variants.

a Gram-negative facultative intracellular bacterium, is the etiological agent of cat-scratch disease and also causes bacillary angiomatosis in immunocompromised individuals. Although the ability to promote vascular endothelial cell proliferation differs among species, variations among strains within remain unclear. angiogenic factor A (BafA) and adhesin A (BadA) have been identified as autotransporters of that are involved in endothelial cell proliferation.

Anti-integrin αvβ6 antibody as a biomarker for diagnosing ulcerative colitis: a nationwide multicenter validation study.

Background: A serum biomarker for diagnosing ulcerative colitis (UC) remains to be established. Although we recently reported an anti-integrin αvβ6 antibody (V6 Ab) for diagnosing UC with high sensitivity and specificity, no large-scale validation study exists. This study aimed to validate the diagnostic value of V6 Ab for UC using a nationwide multicenter cohort study.

Abbreviated or Standard Antiplatelet Therapy After PCI in Diabetic Patients at High Bleeding Risk.

Background: Abbreviated antiplatelet therapy (APT) reduces bleeding without increasing ischemic events in largely unselected high bleeding risk (HBR) patients undergoing percutaneous coronary intervention (PCI). Diabetes mellitus (DM) is associated with higher ischemic risk, and its impact on the safety and effectiveness of abbreviated APT in HBR PCI patients remains unknown.

Objectives: This study sought to investigate the comparative effectiveness of abbreviated (1 month) vs standard (≥3 months) APT in HBR patients with and without DM after biodegradable polymer sirolimus-eluting coronary stent implantation.

Encrusted pyelitis and hyperammonemia due to Corynebacterium urealyticum in a kidney transplant recipient.

Introduction: The bacterium Corynebacterium urealyticum produces urease and can cause encrusted pyelitis, a condition characterized by calcifications of the renal pelvis and ureteral wall, which may obstruct the urinary tract. We describe a case of encrusted pyelitis caused by C. urealyticum in a kidney transplant patient presenting with altered consciousness due to hyperammonemia.
