Time-dependent recovery of renal impairment in patients with newly diagnosed multiple myeloma.

Renal impairment is reported in 20%-50% of patients with newly diagnosed multiple myeloma and is known as a poor prognostic factor. Although several studies have demonstrated that treatment with novel antimyeloma agents improves renal impairment and myeloma itself, the time-dependent clinical course of recovery of renal function has not been extensively studied. We retrospectively collected the data of characteristics and outcomes in consecutive unselected patients diagnosed with and treated for symptomatic multiple myeloma between January 2015 and December 2022, and extracted and analyzed the cases with renal impairment.

Intestinal obstruction caused by disseminated mycobacterium avium complex disease following solid organ transplantation: a case report.

Background: Mycobacterium avium complex (MAC) is a common pathogen causing non-tuberculous mycobacterial infections, primarily affecting the lungs. Disseminated MAC disease occurs mainly in immunocompromised individuals, such as those with acquired immunodeficiency syndrome, hematological malignancies, or those positive for anti-interferon-γ antibodies. However, its occurrence in solid organ transplant recipients is uncommon.

Cutoffs on severity metrics for minimal manifestations or better status in patients with generalized myasthenia gravis.

International consensus guidance and Japanese clinical guidelines for myasthenia gravis (MG) recommend achieving minimal manifestations or better status (MM-or-better) as the severity component of the treatment goal. However, the subjective nature of determining MM can result in ambiguity regarding this category in clinical practice and clinical trials. This study analyzed severity metrics in a large number of MG patients to propose criteria for MM-or-better.

Blood DNA virome associates with autoimmune diseases and COVID-19.

Aberrant immune responses to viral pathogens contribute to pathogenesis, but our understanding of pathological immune responses caused by viruses within the human virome, especially at a population scale, remains limited. We analyzed whole-genome sequencing datasets of 6,321 Japanese individuals, including patients with autoimmune diseases (psoriasis vulgaris, rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), pulmonary alveolar proteinosis (PAP) or multiple sclerosis) and coronavirus disease 2019 (COVID-19), or healthy controls. We systematically quantified two constituents of the blood DNA virome, endogenous HHV-6 (eHHV-6) and anellovirus.

Association Between Kyphosis and Sleep Disturbance in Community-Dwelling Older Adults: The Locomotive Syndrome and Health Outcome in Aizu Cohort Study.

Purpose: Worsening sagittal alignment of the spine, particularly kyphosis, may cause difficulty in assuming a supine position, restricting sleeping posture and movement and potentially leading to sleep disturbances. However, no studies have explored the relationship between sagittal spinal alignment and sleep disturbance. This study aimed to clarify the relationship between sagittal spinal alignment and sleep disturbance.
