Factors Associated with 30-Day Non-Return to Pre-Hospital Residence in Older Patients Hospitalized with Pneumonia or Lower Respiratory Tract Infection: The Role of Serum Albumin and Early Treatment Failure

Akira Gotō, Takayoshi Hozuki, Akihiro Matsumura, Hiroaki Mita et autres

Background/Objectives: Return to the pre-hospital residence is a meaningful patient-centered outcome after hospitalization for pneumonia or lower respiratory tract infection (LRTI). We examined factors associated with 30-day non-return, including prespecified baseline characteristics, the initial empirical antimicrobial therapy pattern, and initial treatment failure …

Association of Somatic Cell Score at First Calving With Milk Productivity and Mortality in Dairy Herds: A Cross‐Sectional Study in Eastern Hokkaido, Japan

Akira Gotō, Mitsuo YOKOI, Naoki Yamamoto, Yoichi Inoue et autres

Over the past decade, the increasing proportion of primiparous cows in Hokkaido dairy herds has resulted in younger herds, but somatic cell count (SCC) has stagnated at around 220,000 cells/mL, preventing milk quality improvements. This study evaluated the impact of elevated postpartum …
