Special Issue Information

Dear Colleagues,

We, Prof. Dr. Florinela Cătoi and Assist. Prof. Dr. Daniela Ciobârcă, are pleased to invite you to contribute to a Special Issue of the journal Nutrients, seeking to explore the nutritional management of obesity and bariatric surgery patients.

Bariatric surgery (BS) has emerged as a first-line weight loss therapy for severe obesity, leading to significant and sustainable weight reduction as well as reductions in comorbidities and mortality. However, the permanent alteration of the gastrointestinal physiology after BS, which results in substantial weight loss, is associated with micronutrient deficiencies (MNDs) in restrictive and malabsorptive procedures.

This Special Issue, titled ”Nutritional Implications in Obesity and Bariatric Surgery”, is open to submissions containing research in the form of original articles, review articles, meta-analyses, etc. Topics to be covered include, but are not limited to:

  • MNDs in obesity;
  • MNDs de novo development after BS;
  • Prophylactic post-operative supplementation;
  • Post-operative adherence to nutritional recommendations and micronutrient supplementation.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Background: Micronutrient deficiencies (MNDs) are commonly reported after bariatric and metabolic surgery, including laparoscopic sleeve gastrectomy (LSG). Nevertheless, the micronutrient status changes over time and the influence of sex or initial body mass index (BMI) on these changes are less explored. This study [...] Read more.
Background: Micronutrient deficiencies (MNDs) are commonly reported after bariatric and metabolic surgery, including laparoscopic sleeve gastrectomy (LSG). Nevertheless, the micronutrient status changes over time and the influence of sex or initial body mass index (BMI) on these changes are less explored. This study aims to investigate the changes in micronutrient levels at 6 and 12 months after LSG and the potential influence of sex or baseline BMI (≥40 kg/m2) on these changes in patients submitted to LSG. Additionally, the frequency of MNDs before and at 12 months after the procedure was investigated. Materials and methods: Fifty patients with obesity underwent LSG and were assessed anthropometrically and nutritionally at baseline and at 6 and 12 months, respectively, after LSG. The changes in micronutrients levels over time were tested by a linear mixed model. Results: Vitamin B12 and vitamin D [25(OH)D] did not change significantly, while iron (p < 0.001), calcium (p = 0.01), and parathormone (p < 0.001) differed significantly from baseline to 12 months after LSG. Ferritin significantly decreased from baseline to 6 months and 12 months after LSG (LS-means, 95% CI: 202 [163, 240] vs. 160 [130, 191] vs. 150 [115, 185]). Sex or initial severe obesity (BMI ≥ 40 kg/m2) exhibited significant modifying effects for 25(OH)D and calcium, respectively. The 25(OH)D levels increased significantly in men, but not in women, while the calcium plasma concentration changed significantly only in patients with initial severe obesity. No significant changes over time were found for MNDs’ frequency (p > 0.05). The most consistent deficiency frequency was observed for 25(OH)D both before and after LSG. Conclusions: Overall, our findings revealed changes in micronutrient status across the follow-up period, except for vitamin B12. Variations in 25(OH)D levels were reported exclusively in men, suggesting that they depend on sex. The calcium plasma concentration showed significant changes exclusively in patients with BMI ≥ 40 kg/m2. MNDs’ frequency was not significantly altered during the study follow-up. Our results reinforce the need for developing national dietary guidelines tailored for Romanian patients following LSG. Full article

Background/Objectives: To evaluate the agreement and discriminant validation of different osteosarcopenic adiposity (OSAd) diagnostic criteria in women post-Roux-en-Y gastric bypass (RYGB) surgery. Methods: Surgery. This is a cross-sectional study with women ≥2 years post-RYGB. OSAd was diagnosed using three criteria: Kelly for OSAd; ESPEN/EASO and SDOC for SO, associated with WHO osteopenia, respectively. Agreement was assessed with Cohen’s Kappa, and the predictive discriminatory capability was evaluated by sensitivity, specificity, and accuracy, using impairment of physical function and the increased risk of fracture as reference standards.; Results: A total of 178 women were evaluated, with a mean age of 45.2 ± 9.6 years old and postoperative time of 6.6 ± 3.6 years. The prevalence of OSAd was 2.2% [Kelly]; 2.8% [ESPEN/EASO + WHO]; 6.2% [SDOC + WHO]. Moderate agreement was found between Kelly and ESPEN/EASO (k = 0.658, p < 0.001), but agreement with SDOC was null (k = 0.104, p = 0.114). All criteria demonstrated high specificity (94.0–98.2%) and low sensitivity (0.0–16.7%), with Kelly showing the highest accuracy (92.7%); Conclusions: Among the evaluated criteria, Kelly presented the highest accuracy and 2.2% of OSAd prevalence. Despite consistently high specificity, all criteria exhibited low sensitivity. These findings highlight the need for more sensitive diagnostic approaches for OSAd in postoperative RYGB populations.
