PurposePreoperative nutrition is beneficial for malnourished cancer patients. Yet, there is little evidence whether or not it should be given to nonmalnourished patients. The aim of this study was to assess the need to introduce preoperative nutritional support in patients without malnutrition at qualification for surgery.MethodsThis was a prospective, two-arm, randomized, controlled, open-label study. Patients in interventional group received nutritional supplementation for 14 days before surgery, while control group kept on to their everyday diet. Each patient’s nutritional status was assessed twice—at qualification (weight loss in 6 months, laboratory parameters: albumin, total protein, transferrin, and total lymphocyte count) and 1 day before surgery (change in body weight and laboratory parameters). After surgery, all patients were followed up for 30 days for postoperative complications.ResultsFifty-four patients in interventional and 48 in control group were analyzed. In postoperative period, patients in control group suffered from significantly higher (p < 0.001) number of serious complications compared with patients receiving nutritional supplementation. Moreover, levels of all laboratory parameters declined significantly (p < 0.001) in these patients, while in interventional arm were stable (albumin and total protein) or raised (transferrin and total lymphocyte count).ConclusionsPreoperative nutritional support should be introduced for nonmalnourished patients as it helps to maintain proper nutritional status and reduce number and severity of postoperative complications compared with patients without such support.

Niedożywienie dotyczy dużej części pacjentów onkologicznych. Prawidłowe postępowanie żywieniowe warunkuje skuteczność i powodzenie leczenia u tych chorych. Ze względu na znaczenie tego zagadnienia, dzięki współpracy towarzystw naukowych: Polskiego Towarzystwa Chirurgii Onkologicznej (PTChO), Polskiego Towarzystwa Onkologicznego (PTO), Polskiego Towarzystwa Onkologii Klinicznej (PTOK) oraz Polskiego Towarzystwa Żywienia Dojelitowego, Pozajelitowego i Metabolizmu (POLSPEN), zostały opracowane standardy leczenia żywieniowego w onkologii. Wstępem do leczenia żywieniowego jest prawidłowa identyfikacja niedożywionych pacjentów. W Polsce hospitalizowani chorzy są poddawani badaniu przesiewowemu w kierunku niedożywienia. Interwencja żywieniowa powinna być dostosowana do sytuacji klinicznej. Polega ona na poradnictwie dietetycznym, stosowaniu doustnych diet przemysłowych (oral nutritional support), żywienia dojelitowego lub żywienia pozajelitowego w warunkach szpitalnych i domowych, z uwzględnieniem sytuacji szczególnych. Clinical nutrition in oncology: Polish recommendations Malnutrition affects a large part of patients with malignant neoplasm. Proper nutritional treatment determines the effectiveness and success of therapy in these patients. Given the importance of this issue, thanks to the collaboration of scientific societies: Polish Society of Surgical Oncology (PTChO), Polish Society of Oncology (PTO), Polish Society of Clinical Oncology (PTOK) and Polish Society for Parenteral, Enteral Nutrition and Metabolism (POLSPEN) standards for nutritional therapy in oncology have been set. An introduction to nutritional therapy is the correct identification of malnourished patients. In Poland, hospitalized patients are subject to screening towards malnutrition. Nutrition

The question of whether anesthetic, analgesic or other perioperative intervention during cancer resection surgery might influence long-term oncologic outcomes has generated much attention over the past 13 years. A wealth of experimental and observational clinical data have been published, but the results of prospective, randomized clinical trials are awaited. The European Union supports a pan-European network of researchers, clinicians and industry partners engaged in this question (COST Action 15204: Euro-Periscope). In this narrative review, members of the Euro-Periscope network briefly summarize the current state of evidence pertaining to the potential effects of the most commonly deployed anesthetic and analgesic techniques and other non-surgical interventions during cancer resection surgery on tumor recurrence or metastasis.

Background: Social media are growing worldwide platforms for unlimited exchange of various content. Owing to their accessibility and short form, they can be utilized as usable, wide-range communication and information tools for companies, scientific communities, patient advocacy organizations, and special interest groups. This study aimed to investigate whether Instagram® profiles can be reliable sources of information and knowledge about nutrition and dietetics. Materials and Methods: Random identification of nutrition-related posts was performed using a built-in website search engine. Posts were searched by five popular hashtags: #nutrition, #nutritionist, #instadiet, #diet, and #dietitian, 250 newest posts of each. Advertisement posts were discarded. Each eligible post was then categorized (dietetics, fitness, motivation, other) and assessed with regard to the quality of nutrition information provided (five levels from none to good quality), popularity (number of followers, likes, and comments), and engagement measures (like, comment, and engagement ratio). Results: A total of 1189 posts were reviewed. The overall quality of the content regarding nutritional knowledge was extremely low (93.9% of all posts), also when divided into categories. Among all posts, 63.8% were categorized as “nutrition and dietetics”, while “fitness”, “motivation”, and “other” categories comprised 8.2%, 4.8%, and 23.2% of the posts, respectively. Posts recognized as dietetics were the most liked (mean n = 116 likes per post) and of the highest quality. However, those motivational raised the greatest degree of engagement (32.7%). Posts with cooking recipes were the most commented. Conclusions: Random post search cannot provide viewers with valuable nutrition information. A dedicated search for high-quality professional profiles is preferred to obtain quality information.
