Ho-Seong Han, South Korea
President IASMEN
Dear colleagues,
I hope this message finds you all in good health. My name is Ho-Seong Han, President of IASMEN.
As I write this in November, it is usually the season when we enjoy the autumn foliage and gradually prepare for winter. However, this year, we have been facing rapid temperature fluctuations, making it difficult to maintain stable health. You may have heard the term “bi-seasonalization of the four seasons.” In countries such as Korea and Japan, where four distinct seasons traditionally exist, spring and autumn have shortened, and 40°C, and just as the heat began to subside, winter-like cold arrived even before temperatures now shift abruptly from summer to winter. This past summer, we experienced several days exceeding the full display of autumn colors. Nevertheless, Korea is currently at the height of its autumn foliage, and the beautiful transition from green to vivid yellow and red continues to bring us joy.
The upcoming ISW is drawing near, and the IASMEN program has been finalized. Once again, we are pleased to present a comprehensive agenda covering the latest and most relevant topics in surgical metabolism and nutrition.
Our sessions range from clinically oriented, practical presentations to educational lectures grounded in basic scientific evidence. Beyond the diseases themselves, surgical stress induces abnormalities in metabolic responses. Furthermore, disruption of the balance between catabolism and anabolism leads to changes in body composition. Metabolism is a dynamic biological process and understanding it is fundamental to clinical practice and to the proper management of metabolic derangements. In the joint session with the Integrated Societies, important metabolic topics across multiple specialties will be discussed, and we strongly encourage all of you to join us.
Many of you are already familiar with the Enhanced Recovery After Surgery (ERAS) program, which has been widely implemented across many countries. This IASMEN will again feature numerous ERAS-related presentations, offering both organ-specific and field-specific updates. Additionally, the joint “Global Surgery Session” with ISS will address the current status and challenges in LMICs, and future directions for international collaboration in ERAS program.
Furthermore, we are delighted to host the second joint session with the Asian Society of Surgical Metabolism and Nutrition (ASSMN), as well as our first collaborative session with the local Mexican society of Surgical Metabolism and Nutrition, CMNCTN. IASMEN continues to expand and evolve both locally and globally.
The upcoming ISW will take place four months earlier than usual, in April. Mexico City in mid-April offers refreshing early-summer weather just before the rainy season begins, with abundant greenery and blooming flowers throughout the city. Like the vibrant jacarandas in full bloom, we hope the ISW will be a lively, inspiring gathering filled with meaningful discussion and exchange.
We very much look forward to meeting you all in Mexico City.
Warmest regards,
Ho-Seong Han
President, IASMEN
