Effects of consecutive bed bathing with weak versus ordinary pressure on skin barrier recovery of hospitalised older adults: A within-person randomised controlled trial.

Aim: Wiping pressure (WP [mmHg]) during bed baths is essential to maintain skin integrity and care quality for older adults. However, effects of different wiping pressures on skin barrier recovery over multiple days remain unclear. This study evaluated and compared the effects of consecutive bed bathing with weak pressure and that with ordinary pressure on skin barrier recovery of hospitalised older adults.

Breaking away from an endemic state of multidrug-resistant by daily sink disinfection.

The detection rate of multidrug-resistant in patients admitted to 2 wards and the intensive care unit decreased from 20.3% (129 of 636 isolates) to 4.2% (37 of 889 isolates) after the start of disinfection of hand washing sinks using alkyl diaminoethylglycine hydrochloride.

Factors associated with household transmission of SARS-CoV-2 omicron variant to health care workers: A retrospective cohort study.

Aim: The aim of this study was to determine the risk factors for household transmission of the omicron variant of SARS-CoV-2.

Background: The household infection rate has been reported to be higher for the omicron variant than for non-omicron variants of SARS-CoV-2. Determination of the risk factors for household transmission of the omicron variant is therefore important.

IgG4-IgE complex interferes with measurement of IgE concentration.

Background And Aims: Patients with immunoglobulin G4 (IgG4)-related disease (IgG4-RD) have elevated immunoglobulin E (IgE) concentration compared to that in healthy individuals, which suggests the occurrence of IgE-mediated allergic reactions. We have previously shown that IgG4 and IgE form a complex in some patients with IgG4-RD. However, it is currently unknown whether and how the presence of the IgG4-IgE complex affects IgE concentration measurements by different assays.

Frequencies of Anti-Troponin I vs Anti-Troponin T Autoantibodies and Degrees of Interference on Troponin Assays.

Objective: Presence of autoantibodies against troponin I (cTnI) or T (cTnT) has been reported to interfere with troponin assays. However, the extent of the interference with the measurement has not been explored sufficiently. The aims of this study were to examine the frequencies of autoantibodies against troponin I and troponin T and how much these antibodies would affect the measurement.

SARS-CoV-2 Omicron detection by antigen tests using saliva.

The Omicron emerged in November 2021 and became the predominant SARS-CoV-2 variant globally. It spreads more rapidly than ancestral lineages and its rapid detection is critical for the prevention of disease outbreaks. Antigen tests such as immunochromatographic assay (ICA) and chemiluminescent enzyme immunoassay (CLEIA) yield results more quickly than standard polymerase chain reaction (PCR).

IgG4-IgE complex in patients with IgG4-related disease.

Background: IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory disease characterized by high IgE levels; however, the physiological significance of elevated IgE levels in patients with IgG4-RD is unclear. Previously, we reported the formation of IgG4-IgE complex in IgG4-RD patients with elevated IgE levels. In this study, we examined the frequency of this complex formation and its relationship with the clinical features in IgG4-RD patients.

IgG4-IgE complex in a patient with IgG4-related disease.

Background: IgE concentrations are occasionally elevated in patients with IgG4-related disease (IgG4-RD). In this report, we describe a novel case of IgG4-RD in which IgE concentrations were discordant between measuring reagents.

Case: An 81-year-old man was diagnosed with IgG4-RD and histological autoimmune pancreatitis, which ensued without treatment.

Diffuse Alveolar Hemorrhage Developing Immediately after Immunosuppressive Treatments in a Patient with Granulomatosis with Polyangiitis Who Had Pulmonary Nodules.

A 65-year-old man was diagnosed with granulomatosis with polyangiitis (GPA) based on the detection of high myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA), vasculitis and granulomas in a lung biopsy specimen and crescentic glomerulonephritis in a kidney biopsy specimen. Soon after the initiation of intravenous methylprednisolone pulse therapy (mPSL pulse) and intravenous cyclophosphamide pulse therapy (IVCY), the patient experienced cough and hemoptysis. Based on emerging anemia and bilateral diffuse lung consolidation on computed tomography, we judged that diffuse alveolar hemorrhage (DAH) was complicated by GPA.

Nanoporous Structure Formation in GaSb, InSb, and Ge by Ion Beam Irradiation under Controlled Point Defect Creation Conditions.

Ion beam irradiation-induced nanoporous structure formation was investigated on GaSb, InSb, and Ge surfaces via controlled point defect creation using a focused ion beam (FIB). ‎This paper compares the nanoporous structure formation under the same extent of point defect creation while changing the accelerating voltage and ion dose. Although the same number of point defects were created in each case, different structures were formed on the different surfaces.

Usefulness of early vascular phase images from contrast-enhanced ultrasonography using Sonazoid for the diagnosis of hypovascular hepatocellular carcinoma.

Aim: This study aimed to evaluate the usefulness of early vascular phase images produced by contrast-enhanced ultrasonography (CE-US) with Sonazoid for the diagnosis of hypovascular hepatocellular carcinoma (HCC).

Methods: Four hundred and seventeen patients with 674 hepatic nodules were evaluated using CE-US with Sonazoid between January 2007 and March 2010. Retrospective analysis was conducted on 49 histologically confirmed nodules showing hypovascularity relative to the surrounding liver tissue in the early vascular phase and no enhancement defect in the Kupffer phase of CE-US with Sonazoid.

Stress-induced cardiomyopathy accompanied by heat stroke.

Heat stroke is a severe illness characterized by a core temperature >40 °C (104 °F) and central nervous system abnormalities, such as delirium, convulsions, or coma, resulting from exposure to environmental heat or strenuous physical experience. We describe a case with high body temperature and coma, who also presented with wide QRS tachycardia and shock. He was initially treated for heat stroke and wide QRS tachycardia.

Usefulness of contrast-enhanced ultrasonography using Sonazoid for the assessment of therapeutic response to percutaneous radiofrequency ablation for hepatocellular carcinoma.

Aim: Accurate assessment of the coagulated area is imperative to achieve an excellent outcome from percutaneous radiofrequency ablation (PRFA) for the treatment of hepatocellular carcinoma (HCC). We evaluated the efficacy of contrast-enhanced ultrasonography (CEUS) with the contrast-enhancing agent Sonazoid for precisely assessing the therapeutic effect of PRFA for HCC.

Methods: We enrolled 87 consecutive patients with solitary naïve HCC of less than 3 cm in diameter.
