Multistage deep learning for classification of Helicobacter pylori infection status using endoscopic images.

Background: The automated classification of Helicobacter pylori infection status is gaining attention, distinguishing among uninfected (no history of H. pylori infection), current infection, and post-eradication. However, this classification has relatively low performance, primarily due to the intricate nature of the task.

A case of fatal disseminated infection with masticator space abscess caused by ESBL-producing K57-ST412 hypervirulent Klebsiella pneumoniae.

A 70-year-old Japanese man with well-controlled diabetes mellitus and chronic kidney disease was hospitalized for an examination of acute renal failure and elevated inflammatory reactions. He had a history of Klebsiella pneumoniae bacteremia without extended-spectrum β-lactamase (ESBL) production five months earlier. The patient was found to have bacteremia due to hypermucoviscous ESBL-producing Klebsiella pneumoniae, and developed septic shock, multiple cerebral infarctions, and an abscess in the left masticatory muscle space.

Vancomycin-associated acute kidney injury in underweight patients: a propensity score matching analysis.

Purpose: To investigate the effect of being underweight on the incidence of vancomycin-associated acute kidney injury (AKI) using propensity score matching analysis.

Methods: This study is a retrospective analysis of patients who received vancomycin and had their serum concentration measured at Kitasato University Hospital between January 1, 2016 and December 31, 2020. Patients were divided into underweight and non-underweight groups based on body mass index (BMI), and propensity score matching analysis was used to evaluate whether underweight affected the incidence of acute kidney injury.

Effects of Cimetidine and Dolutegravir on the Endogenous Drug-Drug Interaction Biomarkers for Organic Cation Transporter 2 and Multidrug and Toxin Extrusion Protein 1 in Healthy Volunteers.

This study was designed to assess the quantitative performance of endogenous drug-drug interaction (DDI) biomarkers (N1-methylnicotinamide (1-NMN), N1-methyladenosine (mA), and creatinine) for the organic cation transporters, OCT2 and MATE1/2K in the kidney. Ten healthy volunteers received cimetidine (400 and 800 mg, single dose) or dolutegravir (50 mg, twice a day) together with metformin (500 mg). Cimetidine and dolutegravir were considered to act mainly as MATE1/2K and OCT2 inhibitors, respectively.

Effects of Hyperbaric Oxygen Therapy for Malignant Bowel Obstruction Caused by Peritoneal Dissemination.

Introduction: This study aimed to investigate the efficacy of hyperbaric oxygen therapy (HBOT) in patients presenting with malignant bowel obstruction (MBO) and peritoneal dissemination.

Materials And Methods: We retrospectively examined whether HBOT affects prognosis following MBO with peritoneal dissemination. This study included 44 patients diagnosed with MBO secondary to peritoneal dissemination at our hospital between January 2013 and December 2022.

An study of metformin adsorption to activated charcoal.

Introduction: Metformin is a biguanide used to manage patients with type 2 diabetes mellitus. However, metabolic acidosis with an elevated lactate concentration and death caused by metformin overdoses are toxicological concerns. Although activated charcoal has been widely used for gastrointestinal decontamination in cases of acute poisoning, there is no evidence regarding its efficacy in treating metformin overdoses.

The Changes in Broad-spectrum Antimicrobial Consumption during the COVID-19 Pandemic in a Japanese Acute Tertiary-care Hospital: An Interrupted Time-series Analysis.

Objective The novel coronavirus disease 2019 (COVID-19) pandemic has spread worldwide, and hospitals in Japan have been forced to respond to the situation. This study evaluated the broad-spectrum antimicrobial use before and during the COVID-19 pandemic in an acute tertiary-care hospital. Methods This single-center, retrospective study was conducted between January 2019 and June 2021.

The importance of infectious disease specialists consulting on a weekly basis in a Japanese tertiary care hospital: A retrospective observational study.

Limited data are available regarding part-time infectious disease consultations (IDCs) and their importance in tertiary care teaching hospitals in Japan. This is a retrospective review of IDCs from June 2016 to March 2021 and describes IDC services provided by part-time infectious disease specialists once a week for 4 hours, and their impact on the quality of medical care, including antimicrobial stewardship. Data, such as the requesting department, requesting reasons, and final diagnoses, were analyzed.

Infectious diseases consultations from general internal medicine physicians in Japan: A descriptive single-center study.

In Japan, general internal medicine (GIM) physicians must be aware of frequently encountered infections because of the shortage of infectious disease (ID) specialists. However, there are currently no epidemiological data on this subject. This study aimed to describe the frequency and pattern of ID consultations requested by GIM physicians in Japan.

[A case of idiopathic spinal cord herniation with incomplete Brown-Séquard syndrome].

A 50-year-old man was referred to our hospital with myelitis associated with a 10-months history of progressive muscle weakness in the left leg. Neurological examinations demonstrated diffuse muscle weakness of the left leg, touch hypoesthesia of the right leg, reduced pain sensation below the right nipple, left pyramidal sign, and urinary incontinence. On the basis of thoracic spinal MRI and thoracic CT myelography, revealing anterior displacement of the spinal cord and enlargement of the posterior subarachnoid space at the Th4 vertebral level, we diagnosed the patient as having idiopathic spinal cord herniation with incomplete Brown-Séquard syndrome.

Impact of the antimicrobial stewardship program on hospital-acquired candidemia.

Antibiotic stewardship programs reduce antibiotic use without negative clinical outcomes. However, epidemiological data describing the relationship between implementing antimicrobial stewardship and candidemia incidence are scarce. This study aimed to evaluate the effect of antibiotic stewardship on the incidence of hospital acquired candidemia.
