Coronavirus Disease 2019 (COVID-19) outbreak caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a major public health problem. The elderly people are the most affected population by the COVID-19 outbreak in terms of mortality and morbidity. Delirium caused by hypoxia, a prominent clinical feature of COVID-19, may increase the need for treatment of Alzheimer's disease (AD) patients (1). Therefore, drug-drug interactions should be considered in AD patients while receiving COVID-19 treatment.

Medical nutrition therapy is one of the core components of the patient management, although its implication is still limited in daily practice globally. Clinicians are in need of guidance that will ease the application of medical nutrition therapy. The first treatment choice in medical nutrition therapy is the use of oral nutritional supplements (ONS) after or concomitant with dietary interventions. The pre and post-graduate curriculum for medical nutrition therapy is limited in most regions, worldwide. A report that is short, clear, and having clear-cut recommendations that will guide the primary healthcare professionals in indications, choice, practical application, follow-up, and stopping ONS would facilitate the application and success of medical nutrition therapy. KEPAN is the Clinical Enteral and Parenteral Nutrition Society of Turkey and is an active member of the European Society for Clinical Nutrition and Metabolism (ESPEN). In this study, we present the KEPAN ONS consensus report on optimal ONS use in medical nutrition therapy as outlined by works of academicians experienced in clinical application of ONS (eight working group academicians and 19 expert group academicians). This report provides 22 clear-cut recommendations in a question-answer format. We believe that this report could have a significant impact in the ideal use of ONS in the context of medical nutrition therapy when clinicians manage everyday patients.

Beslenme desteği, hasta tedavisinin ayrılmaz bir parçasıdır. Bununla birlikte, günlük uygulamalarda beslenme tedavisi hedeflerine ulaşıldığını söylemek zordur. Bu nedenle klinik pratikte beslenme tedavisi uygulamalarını kolaylaştırmaya yönelik girişimlere ihtiyaç vardır. Malnütrisyon tedavisinde ilk seçenekler diyet düzenlemesi ve oral tamamlayıcı nütrisyon ürünleri kullanımıdır. Ancak oral yolla beslenemeyen veya beslenme hedeflerine ulaşılamayan bazı hasta gruplarında tüple beslenme ihtiyacı gerekmektedir. Tüm dünyada tıp fakültesi, beslenme ve diyetetik fakültesi ve uzmanlık eğitimi müfredatları klinik beslenme konusunda genellikle yeterli değildir. Hekim, diyetisyen, hemşire, eczacı ve diğer sağlık profesyonellerine yönelik, enteral beslenme kullanım endikasyonları, uygulanma şekilleri, ürünlerin seçimi, hasta izlemi, komplikasyonların yönetimi ve tedavi sonlandırılmasında yol gösterecek kısa, net ve pratik önerilere odaklı bir rehberin yararlı olacağını düşündük. Bu rehber, alanında deneyimli uzman bir ekip tarafından KEPAN çatısı altında hazırlanmış ve 29 kişiden oluşan KEPAN rehber grubunca onaylanmıştır.
