Nutritional Status of Vegetarian Patients Before and After Bariatric Surgery: a Monocentric Retrospective Observational Case–Control Study

International audienceAbstract: The obesity pandemic is associated with an increasing number of bariatric surgeries which allow improvement in obesity-related comorbidities and life expectancy but potentially induce nutritional deficiencies. Vegetarianism becomes more and more popular and exposes as well to vitamin and micronutrient deficiencies. Only one study has explored the impact of vegetarianism on the preoperative nutritional status of eligible patients for bariatric surgery, but none in postoperative care. Materials and Methods: We conducted a retrospective case–control study in our cohort of bariatric patients, matching 5 omnivores for each vegetarian. We compared their biological profile regarding vitamin and micronutrient blood levels before and 3, 6, 12, and 30 months after surgery. Results: We included 7 vegetarians including 4 lacto-ovo-vegetarians (57%), 2 lacto-vegetarians (29%), and one lacto-ovo-pesco-vegetarian (14%). Three years after surgery with equivalent daily standard vitamin supplementation, the two groups showed a similar biological profile including blood levels of ferritin (p = 0.6), vitamin B1 (p = 0.1), and B12 (p = 0.7), while the total median weight loss at 3 years was comparable (39.1% [27.0–46.6] in vegetarians vs 35.7% [10.5–46.5] in omnivores, p = 0.8). We observed no significant difference between vegetarians and omnivores before surgery regarding comorbidities and nutritional status. Conclusion: It seems that, after bariatric surgery, vegetarian patients taking a standard vitamin supplementation do not show an increased risk of nutritional deficiencies compared to omnivores. However, a larger study with a longer follow-up is needed to confirm these data, including an evaluation of different types of vegetarianism such as veganism.

Risk-Benefit Balance Associated With Obstetric, Neonatal, and Child Outcomes After Metabolic and Bariatric Surgery

International audienceImportanceMetabolic and bariatric surgery (MBS) is the most efficient therapeutic option for severe obesity. Most patients who undergo MBS are women of childbearing age. Data in the scientific literature are generally of a low quality due to a lack of well-controlled prospective trials regarding obstetric, neonatal, and child outcomes.ObjectiveTo assess the risk-benefit balance associated with MBS around obstetric, neonatal, and child outcomes.Design, Setting, and ParticipantsThe study included 53 813 women on the French nationwide database who underwent an MBS procedure and delivered a child between January 2012 and December 2018. Each women was their own control by comparing pregnancies before and after MBS.ExposuresThe women included were exposed to either gastric bypass or sleeve gastrectomy.Main Outcomes and MeasuresThe study team first compared prematurity and birth weights in neonates born before and after maternal MBS with each other. Then they compared the frequencies of all pregnancy and child diagnoses in the first 2 years of life before and after maternal MBS with each other.ResultsA total of 53 813 women (median [IQR] age at surgery, 30 [26-35] years) were included, among 3686 women who had 1 pregnancy both before and after MBS. The study team found a significant increase in the small-for-gestational-age neonate rate after MBS (+4.4%) and a significant decrease in the large-for-gestational-age neonate rate (−12.6%). The study team highlighted that compared with pre-MBS births, after MBS births had fewer occurrences of gestational hypertension (odds ratio [OR], 0.16; 95% CI, 0.10-0.23) and gestational diabetes for the mother (OR, 0.39; 95% CI, 0.34-0.45), as well as fewer birth injuries to the skeleton (OR, 0.27; 95% CI, 0.11-0.60), febrile convulsions (OR, 0.39; 95% CI, 0.21-0.67), viral intestinal infections (OR, 0.56; 95% CI, 0.43-0.71), or carbohydrate metabolism disorders in newborns (OR, 0.54; 95% CI 0.46-0.63), but an elevated respiratory failure rate (OR, 2.42; 95% CI, 1.76-3.36) associated with bronchiolitis.Conclusions and RelevanceThe risk-benefit balance associated with MBS is highly favorable for pregnancies and newborns but may cause an increased risk of respiratory failure associated with bronchiolitis. Further studies are needed to better assess the middle- and long-term benefits and risks associated with MBS.</jats:sec

Management of scabies in children under 15 kg and pregnant or breastfeeding women: recommendations supported by the Centre of Evidence of the French Society of Dermatology

International audienceAlthough scabies is a common disease, questions concerning efficacy, safety, tolerance and galenic formulation persist, in particular regarding its treatment in young children under 15 kg and in pregnant or breastfeeding women. This manuscript reports the recommendations developed by the Centre of Evidence of the French Society of Dermatology. Ivermectin can be proposed as first-line treatment from 2 years on, especially if in doubt about compliance or damaged skin, or in grouped cases; ivermectin can also be proposed as second-line treatment, if necessary, after 2 months

Circulating Receptor Activator of Nuclear Factor kB Ligand and triglycerides are associated with progression of lower limb arterial calcification in type 2 diabetes: a prospective, observational cohort study

Background Lower limb arterial calcification is a frequent, underestimated but serious complication of diabetes. The DIACART study is a prospective cohort study designed to evaluate the determinants of the progression of lower limb arterial calcification in 198 patients with type 2 diabetes. Methods Lower limb arterial calcification scores were determined by computed tomography at baseline and after a mean follow up of 31.20 +/- 3.86 months. Serum RANKL (Receptor Activator of Nuclear factor kB Ligand) and bone remodeling, inflammatory and metabolic parameters were measured at baseline. The predictive effect of these markers on calcification progression was analyzed by a multivariate linear regression model. Results At baseline, mean +/- SD and median lower limb arterial calcification scores were, 2364 +/- 5613 and 527 respectively and at the end of the study, 3739 +/- 6886 and 1355 respectively. Using multivariate analysis, the progression of lower limb arterial log calcification score was found to be associated with (beta coefficient [slope], 95% CI, p-value) baseline log(calcification score) (1.02, 1.00-1.04, p <0.001), triglycerides (0.11, 0.03-0.20, p = 0.007), log(RANKL) (0.07, 0.02-0.11, p = 0.016), previous ischemic cardiomyopathy (0.36, 0.15-0.57, p = 0.001), statin use (0.39, 0.06-0.72, p = 0.023) and duration of follow up (0.04, 0.01-0.06, p = 0.004). Conclusion In patients with type 2 diabetes, lower limb arterial calcification is frequent and can progress rapidly. Circulating RANKL and triglycerides are independently associated with this progression. These results open new therapeutic perspectives in peripheral diabetic calcifying arteriopathy.
