Evaluation using a four-dimensional imaging tool before and after pulmonary valve replacement in a patient with tetralogy of Fallot: a case report.

Background: Pulmonary regurgitation is a common complication after tetralogy of Fallot repair, resulting in right ventricular dysfunction, arrhythmia, and sudden death. However, the indications and optimal timing for pulmonary valve replacement are not fully known. We describe a case in which a four-dimensional imaging tool was useful in the decision to re-operate, thus resulting in decreased energy loss and improved right ventricular function after the re-operation for tetralogy of Fallot.

In-stent Massive Thrombi Formation During Primary Percutaneous Coronary Intervention in a Patient with Acute Myocardial Infarction Complicated with Essential Thrombocythemia.

A 61-year-old man with essential thrombocythemia (ET) presented with acute myocardial infarction (AMI) and underwent primary percutaneous coronary intervention. After stent deployment from the left main (LM) to the left anterior descending artery, intravascular ultrasound revealed thrombi formation in the whole stent. Two days later, optical frequency domain imaging confirmed stent malapposition and thrombi remaining in only the LM.

Feasibility and Safety of Reverse Catheterization Technique of the Superficial Femoral Artery in Single-Stage Endovascular Treatment of Bilateral Infrainguinal Diseases.

Purpose:: We evaluated the feasibility and safety of the reverse catheterization technique of the superficial femoral artery (ReCAT) for single-stage endovascular treatment (EVT) in patients with bilateral infrainguinal diseases.

Materials And Methods:: We retrospectively evaluated 24 consecutive patients (overall median age: 79 years; male patients: 21 [87.5%]) who underwent EVT for bilateral infrainguinal diseases.

Brachial-Ankle Pulse Waves Reflect the Hemodynamics of Valvular Heart Disease.

Background: Brachial-ankle pulse wave (ba-PW) analysis is an established technique for assessing arterial stiffness and cardiovascular risk. The peripheral arterial pulse wave configuration may be useful for valvular heart disease (VHD) detection because it is closely related to the physical signs of VHD; however, few reports have been made assessing the efficacy of ba-PW analysis for VHD screening.

Methods: Consecutive VHD patients scheduled for valve surgery were enrolled in the study.

Simultaneous Loss of Both Atypical Protein Kinase C Genes in the Intestinal Epithelium Drives Serrated Intestinal Cancer by Impairing Immunosurveillance.

Serrated adenocarcinoma, an alternative pathway for colorectal cancer (CRC) development, accounts for 15%-30% of all CRCs and is aggressive and treatment resistant. We show that the expression of atypical protein kinase C ζ (PKCζ) and PKCλ/ι was reduced in human serrated tumors. Simultaneous inactivation of the encoding genes in the mouse intestinal epithelium resulted in spontaneous serrated tumorigenesis that progressed to advanced cancer with a strongly reactive and immunosuppressive stroma.

Humidification Performance of Passive and Active Humidification Devices Within a Spontaneously Breathing Tracheostomized Cohort.

Background: Most heat-and-moisture exchangers (HMEs) for patients with tracheostomy and spontaneously breathing are small and have suction ports that allow some expiratory gas to escape, which loses water vapor held in the expired gas. Recently, a heated-and-humidified high-flow system for spontaneously breathing patients with tracheostomy was developed. Little is known, however, about the humidifying performance of HMEs or heated-and-humidified high-flow systems for spontaneous breathing patients with a tracheostomy.

Angioscopic Evaluation During Balloon Pulmonary Angioplasty in Chronic Thromboembolic Pulmonary Hypertension.

Background: Chronic thromboembolic pulmonary hypertension (CTEPH) is a progressive disorder with a poor prognosis. Recently, balloon pulmonary angioplasty (BPA) has been reported to be an effective treatment for inoperable patients with CTEPH. However, this catheter-based treatment has potentially life-threatening vascular complications.

CRISPR knockouts reveal an endogenous role for ancient neuropeptides in regulating developmental timing in a sea anemone.

Neuropeptides are evolutionarily ancient peptide hormones of the nervous and neuroendocrine systems, and are thought to have regulated metamorphosis in early animal ancestors. In particular, the deeply conserved Wamide family of neuropeptides-shared across Bilateria (e.g.

Effect of High-Flow Nasal Cannula on Thoraco-Abdominal Synchrony in Pediatric Subjects After Cardiac Surgery.

Background: We previously reported the effects of high-flow nasal cannula (HFNC) oxygen therapy on thoraco-abdominal synchrony. This study was designed to clarify the effect of HFNC on thoraco-abdominal synchrony in pediatric subjects after cardiac surgery and to investigate HFNC optimal flow in this population.

Methods: Thoraco-abdominal synchrony was evaluated with respiratory inductive plethysmography.

Fat depot-specific differences of macrophage infiltration and cellular senescence in obese bovine adipose tissues.

Obesity is associated with the chronic inflammation and senescence of adipose tissues. Macrophage is a key mediator of chronic inflammation that infiltrates obese adipose tissue and stimulates metabolic disorders. However, the fat depot-specific differences of macrophage infiltration and senescence, especially the influence on intramuscular adipose tissue, have remained unclear.

Reverse triggering induced by endotracheal tube leak in lightly sedated ARDS patient.

Reverse triggering is respiratory entrainment triggered by the ventilator especially seen among heavily sedated patients. We confirmed reverse triggering induced by auto-triggering in lightly sedated patient through an esophageal pressure monitoring. The reverse triggering frequently caused breath stacking with increased tidal volume.

Balloon pulmonary angioplasty for chronic thromboembolic pulmonary hypertension: A systematic review.

Background: Balloon pulmonary angioplasty (BPA) has been performed for inoperable chronic thromboembolic pulmonary hypertension (CTEPH) or residual pulmonary hypertension after pulmonary endarterectomy (PEA). We performed a systematic review to assess the efficacy and safety of BPA, especially compared to medical treatment or PEA.

Methods: We reviewed all studies investigating pre- and post-treatment pulmonary hemodynamics, mortality, or complications from three electronic databases (PubMed, Cochrane Library, Japan Medical Abstracts Society) prior to February 2017.

Molecular epidemiologic study of Clostridium difficile infections in university hospitals: Results of a nationwide study in Japan.

We conducted a nationwide molecular epidemiological study of Clostridium difficile infection (CDI) in Japan investigated the correlation between the presence of binary toxin genes and CDI severity. This is the first report on molecular epidemiological analyses for CDI in multiple university hospitals in Japan, to our knowledge. We examined 124,484 hospitalized patients in 25 national and public university hospitals in Japan between December 2013 and March 2014, investigating antimicrobial susceptibilities and toxin-related genes for C.

ONO-8590580, a Novel GABA5 Negative Allosteric Modulator Enhances Long-Term Potentiation and Improves Cognitive Deficits in Preclinical Models.

GABA receptors containing 5 subunits (GABA5) are highly expressed in the hippocampus and negatively involved in memory processing, as shown by the fact that GABA5-deficient mice show higher hippocampus-dependent performance than wild-type mice. Accordingly, small-molecule GABA5 negative allosteric modulators (NAMs) are known to enhance spatial learning and memory in rodents. Here we introduce a new, orally available GABA5 NAM that improves hippocampal functions.

Nutritional Screening and Clinical Outcome in Hospitalized Patients with Crohn's Disease.

Background/aims: Hospitalized patients with Crohn's disease (CD) can develop severe nutritional deficits. However, the nutritional screening tools with the most utility for such patients are still unknown.

Methods: Nutritional status of 40 CD patients was assessed on admission using several screening tools and laboratory tests.

Massive and Reproducible Production of Liver Buds Entirely from Human Pluripotent Stem Cells.

Organoid technology provides a revolutionary paradigm toward therapy but has yet to be applied in humans, mainly because of reproducibility and scalability challenges. Here, we overcome these limitations by evolving a scalable organ bud production platform entirely from human induced pluripotent stem cells (iPSC). By conducting massive "reverse" screen experiments, we identified three progenitor populations that can effectively generate liver buds in a highly reproducible manner: hepatic endoderm, endothelium, and septum mesenchyme.

NitroSynapsin therapy for a mouse MEF2C haploinsufficiency model of human autism.

Transcription factor MEF2C regulates multiple genes linked to autism spectrum disorder (ASD), and human MEF2C haploinsufficiency results in ASD, intellectual disability, and epilepsy. However, molecular mechanisms underlying MEF2C haploinsufficiency syndrome remain poorly understood. Here we report that Mef2c (Mef2c-het) mice exhibit behavioral deficits resembling those of human patients.

Correction to: Dapagliflozin decreases small dense low-density lipoprotein-cholesterol and increases high-density lipoprotein 2-cholesterol in patients with type 2 diabetes: comparison with sitagliptin.

Following publication of the original article [1], the authors identified a number of errors. In Result (P.3), Table 1 (P.

Assessment of pathogenesis of infective endocarditis by plasma IgG antibody titer test against periodontal bacteria.

Oral bacteria cause infective endocarditis (IE), so severe periodontitis is thought to be high risk for IE. We suggest the identification of high-risk patients by an IgG antibody titer test against periodontal bacteria might become common screening test.

The Efficacy of a Genetic Analysis of the BMPR2 Gene in a Patient with Severe Pulmonary Arterial Hypertension and an Atrial Septal Defect Treated with Bilateral Lung Transplantation.

Severe pulmonary arterial hypertension (PAH) rarely develops in children with an atrial septal defect (ASD), even those with a large defect. We herein report the case of a 27-year-old man with a moderate-sized secundum ASD and right ventricular failure due to severe PAH, which developed in his early teens. He was diagnosed as having a genetic mutation of the bone morphogenetic protein receptor-2 (BMPR2) gene and was successfully treated with bilateral lung transplantation with ASD path closure.
