Article Abstract
Catalytic and asymmetric domino Michael/aldol reaction of 1,2-dicarbonyl compounds with α,β-unsaturated ketones under the synergetic catalysis of chiral-at-metal rhodium complexes and pyrrolidine to deliver tertiary α-hydroxylation-cyclopentanones (45-89% yields with 81-99% ee and up to >20:1 dr) bearing three contiguous stereogenic centers had been established. Moreover, the scalability and practical utility of this protocol were well demonstrated by employing a gram-scale reaction and some representative transformations.

Intraoperative Cell Salvage for Revision Hip Arthroplasty: A 24-Year Study of Transfusion Requirements.
JB JS Open Access
September 2025
Exeter Hip Unit, Princess Elizabeth Orthopaedic Centre, Royal Devon University Healthcare NHS Foundation Trust, Barrack Road, Exeter, UK.
Background: Revision hip arthroplasty is associated with significant blood loss and a subsequent need for blood transfusion. Intraoperative cell salvage (ICS) is a method of recovering a patient's blood for autologous transfusion. This potentially reduces the need for allogenic blood transfusion (ABT), thus avoiding associated risk and expense.

Department of Surgery, Asan Medical Center, University of Ulsan, College of Medicine, Seoul, Republic of Korea.
Introduction: Breast cancer (BC) treatments can impair fertility in young women, causing considerable distress and potentially influencing treatment decisions, yet comprehensive real-world data on pregnancy outcomes after BC remain limited. This study aims to provide comprehensive real-world data on pregnancy following BC treatment to guide clinical practice and patient counseling.
Methods: We conducted a retrospective cohort study using medical records from a single tertiary medical center in South Korea.

Department of Medicine, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand.
Background: Shock, characterised by circulatory hypoperfusion and cellular hypoxia, represents a critical medical condition requiring immediate attention. Despite its significance, there are limited data on shock incidence and outcomes, particularly within the context of Thailand.
Objectives: This retrospective observational study aimed to investigate the incidence, management and outcomes of shock patients admitted to the internal medicine department of Siriraj Hospital, a referral university hospital in Bangkok, Thailand.
