Comparison of clonal architecture between primary and immunodeficient mouse-engrafted acute myeloid leukemia cells.

Patient-derived xenografts (PDX) are widely used as human cancer models. Previous studies demonstrated clonal discordance between PDX and primary cells. However, in acute myeloid leukemia (AML)-PDX models, the significance of the clonal dynamics occurring in PDX remains unclear.

Clinical value of the HATCH score for predicting adverse outcomes in patients with heart failure.

The HATCH score is employed as a risk assessment tool for atrial fibrillation (AF) development. However, the impact of the HATCH score on the long-term adverse outcomes in patients with acute heart failure (AHF) remains unknown. We investigated the clinical value of the HATCH score in patients with AHF.

Comparison of clinical outcomes, including the wound healing rate, between inframalleolar bypass to the pedal artery and that to the pedal branch artery in the modern endovascular era.

Objective: Inframalleolar (IM) bypass has been reported to demonstrate acceptable patency and limb salvage in patients with chronic limb-threatening ischemia. However, wound healing after IM bypass and comparisons between pedal artery (PA) bypass and pedal branch artery (PBA) bypass are lacking.

Methods: We reviewed prospectively collected data from 208 consecutive patients after IM bypass performed over a period of 6 years.

Relationship between spleen size and exercise tolerance in advanced heart failure patients with a left ventricular assist device.

Objective: Spleen volume increases in patients with advanced heart failure (HF) after left ventricular assist device (LVAD) implantation. However, the relationship between spleen volume and exercise tolerance (peak oxygen consumption [VO]) in these patients remains unknown. In this exploratory study, we enrolled 27 patients with HF using a LVAD (median age: 46 years).

Splenic size as an indicator of hemodynamics and prognosis in patients with heart failure.

The spleen is an important immune organ that releases erythrocytes and monocytes and destroys aged platelets. It also reserves 20-30% of the total blood volume, and its size decreases in hypovolemic shock. However, the clinical significance of splenic size in patients with heart failure (HF) remains unclear.

Carotid Endarterectomy Requiring Removal of the Superior Horn of Thyroid Cartilage: Case Report and Literature Review.

Carotid endarterectomy (CEA) is an established surgical procedure for carotid stenosis. We present the case of a 74-year-old man who underwent CEA for symptomatic internal carotid artery (ICA) stenosis. During the operation, we found that the hyoid bone (HB) and the superior horn of the thyroid cartilage covered the carotid sheath, preventing adequate visualization.

[Research on the Ratio of Anti-Cancer Drug Purchase Costs at Municipal Hospitals in the Aichi Prefecture].

We performed a study on the ratio of anti-cancer drug purchase costs at municipal hospitals in Aichi using meeting materials from the 2020 Aichi Prefectural Public Hospital Pharmacy Directors' Association. The ratio of anti-cancer drug purchase costs to all drug purchase costs at 17 hospitals was 41.5%(average)and 37.

The Tokai Study Group for Therapeutic Radiology and Oncology (TOSTRO) started managing T1 glottic cancer using 2.25 Gy/fraction radiotherapy in 2011. The aim was to evaluate the local control (LC) rate and toxicity with 2.

＜Editors' Choice＞ Prevalence of acute coronary syndrome during the pandemic of COVID-19 in the Tokai Region of Japan.

The outbreak of coronavirus disease 19 (COVID-19) has had a great impact on medical care. During the COVID-19 pandemic, the rate of hospital admissions has been lower and the rate of in-hospital mortality has been higher in patients with acute coronary syndrome (ACS) in Western countries. However, in Japan, it is unknown whether the COVID-19 pandemic has affected the incidence of ACS.

Angioedema Caused by Drugs That Prevent the Degradation of Vasoactive Peptides: A Pharmacovigilance Database Study.

Angioedema results from the decreased degradation of vasoactive peptides such as substance P and bradykinin. In this study, we sought to clarify whether dipeptidyl peptidase-4 (DPP-4) and angiotensin-converting enzyme (ACE) inhibitors that suppress the degradation of substance P and bradykinin are involved in angioedema onset. We calculated information coefficients (ICs) by performing a disproportionality analysis to evaluate DPP-4/ACE inhibitor-induced angioedema using the Japanese Adverse Drug Event Report (JADER) database.

An infant case of pseudohypoaldosteronism type1A caused by a novel NR3C2 variant.

Pseudohypoaldosteronism type1A (PHA1A) is the renal form of pseudohypoaldosteronism with autosomal dominant inheritance. PHA1A is caused by haploinsufficiency of the mineralocorticoid receptor, which is encoded by NR3C2. We encountered an infant who was diagnosed with PHA1A due to hyponatremia, hyperkalemia, and poor weight gain in the neonatal period.

Artificial intelligence-based diagnosis of upper gastrointestinal subepithelial lesions on endoscopic ultrasonography images.

Background: Endoscopic ultrasonography (EUS) is useful for the differential diagnosis of subepithelial lesions (SELs); however, not all of them are easy to distinguish. Gastrointestinal stromal tumors (GISTs) are the commonest SELs, are considered potentially malignant, and differentiating them from benign SELs is important. Artificial intelligence (AI) using deep learning has developed remarkably in the medical field.

Blood culture-negative endocarditis caused by : a case report.

is well known as a causative organism of cat scratch disease. Although this bacterium infrequently involves the heart, the diagnosis is difficult to confirm. A 75-year-old woman who had a pet cat presented with pancytopenia, hepatosplenomegaly, and low-grade fever.

E-PASS scoring system serves as a predictor of short- and long-term outcomes in gastric cancer surgery.

Purposes: This study aimed to evaluate the estimation of the physiological ability and surgical stress (E-PASS) scoring system for predicting the short- and long-term outcomes in gastric cancer (GC) surgery.

Methods: We analyzed a multi-institutional dataset to study patients who underwent gastrectomy with a curative intent between 2010 and 2014. This study evaluated the associations between the optimal E-PASS score cutoff value and the following outcomes: (1) the incidence of postoperative complications in stage I-III GC patients and (2) the prognosis in stage II-III GC patients.

Peripheral combination treatment of leptin and an SGLT2 inhibitor improved glucose metabolism in insulin-dependent diabetes mellitus mice.

We investigated whether peripheral combination treatment of a sodium-glucose cotransporter 2 (SGLT2) inhibitor and leptin improves glucose metabolism in insulin-dependent diabetes mellitus (IDDM) model mice. Twelve-week-old male C57BL6 mice were intraperitoneally administered a high dose of streptozotocin to produce IDDM. IDDM mice were then divided into five groups: SGLT2 inhibitor treatment alone, leptin treatment alone, leptin and SGLT2 inhibitor co-treatment, untreated IDDM mice, and healthy mice groups.

GABA receptor signaling in the caudate putamen is involved in binge-like consumption during a high fat diet in mice.

Previous studies suggest that signaling by the gamma-aminobutyric acid (GABA) type B receptor (GABAR) is involved in the regulation of binge eating, a disorder which might contribute to the development of obesity. Here, we show that intermittent access to a high fat diet (HFD) induced binge-like eating behavior with activation of dopamine receptor d1 (drd1)-expressing neurons in the caudate putamen (CPu) and nucleus accumbens (NAc) in wild-type (WT) mice. The activation of drd1-expressing neurons during binge-like eating was substantially increased in the CPu, but not in the NAc, in corticostriatal neuron-specific GABAR-deficient knockout (KO) mice compared to WT mice.

The importance of choosing the right strategy to treat small cell carcinoma of the cervix: a comparative analysis of treatments.

Background: Standard treatments for small cell carcinoma of the cervix (SCCC) have not been established. In this study, we aimed to estimate the optimal treatment strategy for SCCC.

Methods: This was a multicenter retrospective study.

Clinical outcomes and predictors of restenosis in patients with femoropopliteal artery disease treated using polymer-coated paclitaxel-eluting stents or drug-coated balloons.

Both polymer-coated paclitaxel-eluting stents (PC-PESs) and drug-coated balloons (DCBs) are used in conjunction with endovascular therapy (EVT) for the treatment of peripheral artery disease (PAD). We aimed to identify the risk factors for the loss of patency following the use of PC-PES and DCB in a real clinical setting. We assessed the multi-center registry data of 151 lesions from 151 patients who underwent EVT for symptomatic PAD in the superficial femoral and proximal popliteal arteries using PC-PES or DCB.

Prognostic impact of a microscopic positive margin in patients undergoing gastrectomy for gastric cancer: a propensity score‑matched analysis of a multi‑institutional dataset.

Purpose: We analyzed the effect of a microscopic positive margin on survival outcomes after gastrectomy for gastric cancer METHODS: We analyzed a multi-institutional dataset to study patients who underwent gastrectomy with curative intent between 2010 and 2014. We used propensity score matching to strictly balance the patients' oncological features, backgrounds, and postoperative treatment to compare the survival outcomes of those with microscopic positive margins and those with negative margins.

Results: Among 3029 patients, 32 (1.

Novel Prognostic Score for recurrent or metastatic head and neck cancer patients treated with Nivolumab.

Although several prognostic factors in nivolumab therapy have been reported in recurrent or metastatic head and neck cancer (RM-HNC) patients, these factors remain controversial. Here, we conducted a multicenter retrospective cohort study to investigate the impact of clinico-hematological factors on survival in RM-HNC patients treated with nivolumab. We reviewed 126 RM-HNC patients from seven institutes.
