Previous medical history could be unavailable in unconscious or demented patients. This study aimed to assess the ketone bodies serum levels in patients undergoing elective surgeries and to determine the possible correlation between ketone bodies serum levels and preoperative body weight loss. The study included 21 patients who underwent elective surgery. Hyperketonemia, defined as ketone bodies over 1 mmol\/L, was observed in seven (33.3%) patients. Patients with hyperketonemia had significantly higher preoperative percentage body weight loss (p = 0.04) and higher nutritional risk scores prior to surgery (p = 0.04). Serum glucose and the percentage of body weight loss were associated with increased ketone bodies serum levels (Odds Ratios: 0.978 (0.961\u20130.996, p = 0.019) and 1.222 (1.0\u20131.492, p = 0.05), respectively). A significant linear correlation was found between the percentage of body weight loss and both ketones bodies (r2 = 0.25, p = 0.02) and albumin serum levels (r2 = 0.19, p = 0.04). Our study\u2019s results might suggest a positive association between preoperative body weight loss and ketone bodies serum levels. The observation between increased ketone bodies serum levels in patients and preoperative body mass loss merits further research.<\/jats:p>","DOI":"10.3390\/ijerph19116573","type":"journal-article","created":{"date-parts":[[2022,5,28]],"date-time":"2022-05-28T01:40:45Z","timestamp":1653702045000},"page":"6573","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Serum Ketone Levels May Correspond with Preoperative Body Weight Loss in Patients Undergoing Elective Surgery: A Single-Center, Prospective, Observational Feasibility Study"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8434-6812","authenticated-orcid":false,"given":"Pawe\u0142","family":"Kutnik","sequence":"first","affiliation":[{"name":"II Department of Anaesthesiology and Intensive Care, Medical University of Lublin, Staszica 16, 20-081 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6183-811X","authenticated-orcid":false,"given":"Micha\u0142","family":"Borys","sequence":"additional","affiliation":[{"name":"II Department of Anaesthesiology and Intensive Care, Medical University of Lublin, Staszica 16, 20-081 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7637-6387","authenticated-orcid":false,"given":"Grzegorz","family":"Buszewicz","sequence":"additional","affiliation":[{"name":"Laboratory of Forensic Toxicology, Department of Forensic Medicine, Medical University of Lublin, Jaczewskiego 8b, 20-090 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8529-484X","authenticated-orcid":false,"given":"Pawe\u0142","family":"Piwowarczyk","sequence":"additional","affiliation":[{"name":"II Department of Anaesthesiology and Intensive Care, Medical University of Lublin, Staszica 16, 20-081 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcin","family":"Osak","sequence":"additional","affiliation":[{"name":"Laboratory of Forensic Toxicology, Department of Forensic Medicine, Medical University of Lublin, Jaczewskiego 8b, 20-090 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4184-9305","authenticated-orcid":false,"given":"Grzegorz","family":"Teresi\u0144ski","sequence":"additional","affiliation":[{"name":"Department of Forensic Medicine, Medical University of Lublin, Jaczewskiego 8b, 20-090 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9025-6717","authenticated-orcid":false,"given":"Miros\u0142aw","family":"Czuczwar","sequence":"additional","affiliation":[{"name":"II Department of Anaesthesiology and Intensive Care, Medical University of Lublin, Staszica 16, 20-081 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"799","DOI":"10.1079\/BJN20041258","article-title":"Malnutrition in hospital outpatients and inpatients: Prevalence, concurrent validity and ease of use of the \u2018malnutrition universal screening tool\u2019 (\u2018MUST\u2019) for adults","volume":"92","author":"Stratton","year":"2004","journal-title":"Br.
