An 80-year-old woman presented with primary central nervous system (CNS) lymphoma manifesting as progressive disorientation and loss of activity. She received three cycles of high-dose methotrexate. The tumor shrank after two cycles and her mental status improved, but she suffered tumor recurrence. The second-line treatment consisted of four cycles of rituximab but the tumor enlarged. She was then treated with three cycles of temozolomide. Magnetic resonance imaging revealed no evidence of disease. Her mental status and performance status improved, and she suffered no toxicity. She is able to pursue her daily life without recurrence after 16 cycles of temozolomide. Temozolomide may be effective against relapsed primary CNS lymphoma without causing neurotoxicity in the elderly.

Type 2 diabetes (T2D) frequently coexists with cardiorenal complications. Therefore, a holistic approach to patient management is required, with specialists such as primary care physicians, cardiologists, endocrinologists, and nephrologists working together to provide patient care. Although glycemic control is important in the management of T2D, patients with T2D and acceptable glycemic control are still at risk from cardiovascular (CV) events such as stroke, heart attack, and heart failure (HF).

The current study investigates and compares the biological effects of ultrathin conformal coatings of zirconium dioxide (ZrO) and vanadium pentoxide (VO) on osteoblastic MG-63 cells grown on TiO nanotube layers (TNTs). Coatings were achieved by the atomic layer deposition (ALD) technique. TNTs with average tube diameters of 15, 30, and 100 nm were fabricated on Ti substrates (via electrochemical anodization) and were used as primary substrates for the study.

Purpose: To explore the experiences of long-term sick-listed employees and those of employers with communication and collaboration during sick leave and the return-to-work (RTW) process.
Methods: Previously long-term sick-listed employees ( = 9) and employers ( = 9) were interviewed about their experiences with communication and collaboration during sick leave and RTW. Thematic analysis, utilizing patient journey mapping was applied to analyze and map out their experiences.
Outliers of Treatment Frequency in Retinal Vein Occlusion: 24-Month Comparative Analysis of Fight Retinal Blindness! Practitioners.

The Save Sight Institute, Sydney Medical School, the University of Sydney, Sydney, New South Wales, Australia.
Background: We aimed to describe a 2-year outcome of eyes managed by practitioners benchmarked using a funnel plot by their frequency of treatment using vascular endothelial growth factor (VEGF) inhibitors for naive retinal vein occlusion (RVO).
Methods: A multicentre, international, observational study of 29 doctors in 12 countries managing 1110 eyes with RVO commencing VEGF inhibitors between 1 January 2012-2022 tracked in the Fight Retinal Blindness! registry.
Results: We identified 3 outlying 'intensive' practitioners (managing 350/1110 eyes [32%]), 22 'typical' practitioners (604/1110, [54%]) and 4 outlying 'relaxed' practitioners (156/1110, [14%]) with respective 24-month outcomes in Branch and Central RVO including the primary outcome, mean adjusted change in visual acuity (VA) in BRVO: +16.
Indocyanine Green Fluorescence Plus Blue Dye for Sentinel Lymph Node Biopsy in Patients Undergoing Neoadjuvant Chemotherapy for Breast Cancer: A Multicenter, Prospective Cohort Study.
Thorac Cancer
December 2024
Breast Disease Center, Peking University People's Hospital, Beijing, China.
Background: Sentinel lymph node biopsy (SLNB) using radioisotope tracer plus blue dye is the gold standard after neoadjuvant chemotherapy (NAC) in initially cN1 breast cancer patients, but clinical use still has limitations. This study aims to examine diagnostic performance of dual indocyanine green (ICG) and methylene blue tracing for SLNB in patients who have completed NAC for breast cancer with initially cN1 disease.
Methods: Adult women (20-80 years of age) scheduled to undergo NAC for biopsy-proven cT0-3N1M0 primary invasive breast cancer were consecutively enrolled in this prospective, multicenter, cohort study.
