Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit manuscripts for a new Special Issue of the journal Nutrients entitled “Nutrition Guidelines for Bariatric Surgery Patients”. Surgical treatment is now considered the most effective treatment for obesity. However, without proper dietary management, it does not achieve the expected results. Improper dietary management causes complications, such as severe nutritional deficiencies and intolerances, which in turn can promote a poor nutritional status and its consequences (decreased immunity, impaired wound healing and decreased basal metabolism). With the increasing prevalence of obesity, the number of people undergoing this form of treatment is steadily increasing, so it is necessary to clarify dietary and postoperative supplementation recommendations, considering special groups of patients, including children and adolescents, pregnant and lactating women and patients before and after organ transplantation. We encourage the submission of both review papers and original research articles.

Background/Objectives: Malnutrition frequently occurs following bariatric surgery and can lead to higher morbidity rates, hospitalizations, and extended hospital stays. Nutritional assessment tools such as the Global Leadership Initiative on Malnutrition (GLIM) are not validated for diagnosis of malnutrition following bariatric surgery. This study aimed to assess the validity of GLIM criteria in evaluating the nutritional status of post-sleeve gastrectomy patients compared to the Subjective Global Assessment (SGA). Methods: A total of 47 adult patients who underwent sleeve gastrectomy (SG) from 6 months to 2 years prior were evaluated using the GLIM and SGA. Additionally, multiple pass 24 h recall was collected for two days, and macronutrient analyses were conducted using ESHA software (version 11.11.x). Agreement between both tools was determined using Kappa (κ) statistics, and the Receiver Operating Characteristics (ROC) curve was used to establish sensitivity and specificity. Results: The study found that malnutrition was diagnosed in 48.9% and 42.6% of patients according to the GLIM and SGA criteria, respectively. The GLIM criteria exhibited inadequate accuracy (AUC = 0.533; 95% CI, 0.38–0.72) with a sensitivity and specificity of 55.0% and 55.6%, respectively. The agreement between both tools was determined to be poor (κ = 0.104). Conclusions: GLIM did not show sufficient agreement with SGA. Consequently, the criteria of GLIM may need revision for better diagnosis of malnutrition in post-sleeve gastrectomy patients. Full article

Background: Sleeve gastrectomy (SG) has become the predominant bariatric surgery, leading to significant weight loss and reductions in obesity-related complications. However, postoperative gastrointestinal symptoms such as constipation and bloating are common. This study aims to evaluate the impact of probiotic supplementation on postoperative gastrointestinal symptoms in patients undergoing SG. The secondary aim is to analyze laboratory and stool test results. Materials and methods: This prospective, placebo-controlled study included patients undergoing SG at a single center. Participants were adults without specific gastrointestinal diseases. They were randomly assigned to either the Probiotics or Controls group. Gastrointestinal symptoms and laboratory and stool tests were assessed before surgery and one month after. Results: Thirty-one patients participated, with 15 in the Probiotics group and 16 in the Controls group. Probiotic supplementation significantly increased the number of stools per week (p = 0.027) and reduced constipation incidence (p = 0.002). Patients in the Probiotics group reported easier defecation and greater bowel movement completeness (p = 0.015, p = 0.004). No significant differences in weight loss or laboratory tests were observed between the groups. Stool microbiota analysis showed a return to normal levels of Enterococcus faecalis, Enterococcus faecium, and Clostridium perfringens in the Probiotics group and an increase in the Controls group. Conclusions: Probiotic supplementation after SG significantly reduces constipation without adverse effects. These findings suggest that incorporating probiotics into postoperative care protocols can enhance patient comfort and recovery. Full article
