Number of masseteric electromyographic waveforms during analysis periods with/without excluding time zones after going to bed and before getting up in sleep bruxism assessment.

Objective: This study aimed to clarify differences in assessment of sleep bruxism (SB) using electromyography (EMG) among analysis periods with/without excluding time zones after going to bed (GB) and before getting up (GU).

Methods: Masseteric EMG of 22 outpatients clinically diagnosed as SB was measured. Sleep onset (SO) and waking up (WU) were determined using a wearable motion monitor.

Applicability of the regression approach for histological multi-class grading in clear cell renal cell carcinoma.

The histological grading of carcinoma has been one of the central applications of task-specific deep learning in pathology. The deep learning method has pushed away the regression approach, which has been exploited for two-class classification, to address multi-class classification. However, the applicability of the regression approach on multi-class carcinoma grading has not been extensively investigated.

Immediate postplacental intrauterine device placement: retrospective cohort study of expulsion and associated risk factors.

Background: Postpartum contraception is typically provided during postpartum visits. When desired and accessible, the immediate postpartum period provides an additional opportunity to increase the use of more effective contraceptive methods to potentially reduce subsequent unintended pregnancies and improve pregnancy outcomes. In New York State, recent policy changes expanded Medicaid coverage to include immediate postplacental intrauterine device insertion.

Dynamics in the Prostate Immune Microenvironment Induced by Androgen Deprivation Therapy.

Background: The influence of testosterone on the prostate's immune microenvironment remains unclear. This study aims to elucidate the dynamics of immune cells in the prostate following androgen deprivation therapy (ADT).

Methods: We retrospectively compared prostate needle biopsy and radical prostatectomy specimens from 33 patients who underwent both procedures, along with neoadjuvant ADT at a single institution.

Multifocal meningoencephalitis after vaccination against COVID-19.

We report the case of an 84-year-old male patient who was transferred to our hospital because of impaired consciousness and high fever, and died about 10 weeks after his fourth "coronavirus disease 2019" (COVID-19) vaccination. Autopsy revealed acute ischemic change with microhemorrhage and perivascular T-cell infiltration in the thalamus, pons, and cerebellum, which were considered to be related to neurological symptoms. There were dilatation of the right ventricle, accumulation of pleural effusion, and ascites, suggesting right heart failure.
