Perioperative Nutritional Management in Enhanced Recovery after Bariatric Surgery.

Obesity is a crucial health problem because it leads to several chronic diseases with an increased risk of mortality and it is very hard to reverse with conventional treatment including changes in lifestyle and pharmacotherapy. Bariatric surgery (BS), comprising a range of various surgical procedures that modify the digestive tract favouring weight loss, is considered the most effective medical intervention to counteract severe obesity, especially in the presence of metabolic comorbidities. The Enhanced Recovery After Bariatric Surgery (ERABS) protocols include a set of recommendations that can be applied before and after BS.

The paradox of Zeno in bariatric surgery weight loss: Superobese patients run faster than morbidly obese patients, but can't overtake them.

Introduction: Superobesity (SO) is defined as a BMI > 50 Kg/m, and represents the extreme severity of the disease, resulting in a challenge for the surgeons.

Methods: In this retrospective study we aimed to compare the outcomes of SO patients compared to morbidly obese (MO) patients.

Results: We included in this study 154 MO patients, with a median preoperative BMI of 40.

Controversial Role of Robot in Primary and Revisional Bariatric Surgery Procedures: Review of the Literature and Personal Experience.

Laparoscopy is the surgical standard of care for bariatric procedures; however, during the last two decades, the robotic approach has gained increasing interest. It is currently considered a safe and effective alternative to laparoscopy. This literature review investigates the role of the robotic approach for primary and revisional bariatric procedures, with the particular aim of comparing this technique with the standard-of-care laparoscopic approach.

Fatty Acid Metabolism and Derived-Mediators Distinctive of PPAR-α Activation in Obese Subjects Post Bariatric Surgery.

Bariatric surger (BS) is characterized by lipid metabolic changes as a response to the massive release of non-esterified fatty acids (NEFA) from adipose depots. The study aimed at evaluating changes in polyunsaturated fatty acids (PUFA) metabolism and biosynthesis of the lipid mediators -acylethanolamines (NAE), as indices of nuclear peroxisome proliferator-activated receptor (PPAR)-α activation. The observational study was performed on 35 subjects (27 female, 8 male) with obesity, undergoing bariatric surgery.

Liver transplantation for recurrent hepatic adenoma.

Hepatic adenoma (HA) is a rare indication for liver transplantation (LTx). So far 20 cases of LTx for HA are reported in PubMed. In rare cases HA presents as multiple hepatic adenomas or recurrent adenoma after initial liver resection and in such cases LTx is the only potential cure and prevents the risk of bleeding or cancer transformation into hepatocellular carcinoma.

A Case of Acute Aortic Dissection Type B Associated with Cushing's Syndrome.

Unlabelled: We report a case of a 63-year-old man, with a previous history of hypertension and glucose intolerance associated troncular obesity that was emergently admitted to our Institution for evaluation of a severe, constant posterior chest pain which radiated anteriorly and dyspnoea with a suspected diagnosis of acute aortic dissection. A CT scan of thorax and abdomen demonstrated a dissection starting just below left succlavian artery and extending downward to the left renal artery, involving the celiac tripod and superior mesenteric artery. The dissection was classified as Stanford B, De Bakey III.

Role of platelet-derived growth factor and transforming growth factor beta1 the in the regulation of metalloproteinase expressions.

Background: We investigated the role and influence of platelet derived growth factor (PDGF) and transforming growth factor beta1 (TGF) in the pathologic mechanism at the basis of plaque instability regulating the expression of matrix metalloproteinases (MMPs).

Methods: Plaques obtained from 70 patients who underwent carotid endarterectomy were classified histologically as stable or unstable. Serum levels of PDGF and TGF were measured pre- and postoperatively.
