Efficacy and safety of lascufloxacin for nursing- and healthcare-associated pneumonia: A single-arm, open-label clinical trial.

Background: Nursing- and healthcare-associated pneumonia (NHCAP) constitutes most of the pneumonia in elderly patients including aspiration pneumonia in Japan. Lascufloxacin (LSFX) possesses broad antibacterial activity against respiratory pathogens, such as Streptococcus spp. And anaerobes inside the oral cavity.

Comparison on removal performance of virus, antibiotic-resistant bacteria, cell-associated and cell-free antibiotic resistance genes, and indicator chemicals by ozone in the filtrated secondary effluent of a sewage treatment plant.

Due to the widespread appearance of viruses, antibiotic-resistant bacteria (ARBs), and antibiotic resistance genes (ARGs) in the aquatic environment, more powerful oxidation processes such as ozonation are needed to enhance the efficiency of their inactivation and removal during wastewater treatment. However, information is lacking on the elimination rates of viruses, ARBs, cell-associated ARGs (ca-ARGs), and cell-free ARGs (cf-ARGs) during ozonation. This study examined the kinetics and dose-dependent inactivation of a virus (MS2 coliphage) and an ARB (Ampicillin-resistant [Amp] E.

The prognostic factors for cryptococcal meningitis in non-human immunodeficiency virus patients: An observational study using nationwide database.

Background: Cryptococcal meningitis (CM) is an invasive fungal infection with a poor prognosis that often occurs in both healthy individuals and compromised hosts, such as patients infected with human immunodeficiency virus (HIV). Unlike CM in HIV patients, evidence regarding CM in non-HIV patients is limited to small retrospective studies.

Objective: To identify the pretreatment prognostic factors for CM in non-HIV patients.

Antifungal susceptibility profiles of Cryptococcus neoformans strains clinically isolated from non-HIV-infected patients in Nagasaki, Japan.

Data on antifungal susceptibility of Cryptococcus neoformans are limited in Japan. A total of 89 C. neoformans strains isolated from 83 non-human immunodeficiency virus-infected patients with cryptococcosis between 1997 and 2021 in Nagasaki, Japan, were investigated.

Screening and Synthesis of Tetrazole Derivatives that Inhibit the Growth of Cryptococcus Species.

Cryptococcosis has become a major health problem worldwide and caused morbidity and mortality in immunocompromised patients, especially those infected with human immunodeficiency virus (HIV). Despite the global distribution of cryptococcosis, the number and types of the available antifungals are limited, and the treatment outcomes in HIV patients are generally poor. In this study, we screened a compound library and identified one tetrazole derivative as an efficient inhibitor of Cryptococcus neoformans and Cryptococcus gattii.

Unusual presentation of breast adenoid cystic carcinoma resembling adenomyoepithelioma with multiple distinct foci.

We describe an unusual case of multifocal breast adenoid cystic carcinoma (AdCC) with adenomyoepitheliomatous morphology. Most breast AdCCs are unifocal and only four cases of multifocal AdCC have been reported previously, however, to our best knowledge, multifocality in AdCC confirmed by molecular analysis has not been reported, so this report adds to the literature on this unique presentation. An 80-year-old woman presented with a left breast mass at 1 o'clock and non-mass enhancement lesion at 5 o'clock on imaging.

Big-Volume SliceGAN for Improving a Synthetic 3D Microstructure Image of Additive-Manufactured TYPE 316L Steel.

A modified SliceGAN architecture was proposed to generate a high-quality synthetic three-dimensional (3D) microstructure image of TYPE 316L material manufactured through additive methods. The quality of the resulting 3D image was evaluated using an auto-correlation function, and it was discovered that maintaining a high resolution while doubling the training image size was crucial in creating a more realistic synthetic 3D image. To meet this requirement, modified 3D image generator and critic architecture was developed within the SliceGAN framework.

Evaluation of a Novel R1354H Mutation Associated with Caspofungin Resistance in Using the CRISPR-Cas9 System.

Outbreaks of invasive infections, with high mortality rates, caused by multidrug-resistant have been reported worldwide. Although hotspot mutations in are an established cause of echinocandin resistance, the actual contribution of these mutations to echinocandin resistance remains unknown. Here, we sequenced the gene of a caspofungin-resistant clinical isolate (clade I) and identified a novel resistance mutation (G4061A inducing R1354H).

Acute Dacryoadenitis due to Primary Epstein-Barr Virus Infection.

We herein present the case of a 28-year-old male patient who presented with fever and bilateral upper eyelid edema without other upper airway symptoms and was diagnosed with acute dacryoadenitis due to Epstein-Barr virus (EBV) infection. The patient's medical history was unremarkable. Laboratory tests revealed lymphocytosis with atypical lymphocytes and abnormal liver function tests.

Imaging Mass Spectrometry (IMS) for drug discovery and development survey: Results on methods, applications and regulatory compliance.

Imaging mass spectrometry (IMS) is increasingly used for drug discovery and development to understand target enagement, tissue distribution, drug toxicity, and disease mechanisms, etc. However, this is still a relatively new technique that requires further development validation before it will be an acceptable technique to support regulated development of new drugs. Thus, best practices will need to be established to build more confidence and gain wider acceptance by the scientific community, pharmaceutical industry, and regulatory authorities.

Comprehensive Genomic Survey of Antimicrobial-Resistance Bacteria in the Sewage Tank Replacement with Hospital Relocation.

Background: Excrement containing antimicrobial-resistant bacteria (ARB) is discharged from the hospital sewage through wastewater treatment plants (WWTP) into rivers, increasing the antimicrobial resistance (AMR) burden on the environment.

Purpose: We illustrate the contamination of hospital sewage tanks with ARB harboring antimicrobial resistance genes (ARGs) using comprehensive metagenomic sequencing. During the study period, we moved to a new hospital building constructed for renovation.
