Prediabetes remission after bariatric surgery: a 4-years follow-up study.

Background: Bariatric surgery leads to weight loss and to cardiometabolic risk improvement. Although prediabetes remission after bariatric surgery is biologically plausible, data on this topic is scarce. We aimed to assess prediabetes remission rate and clinical predictors of remission in a 4 year follow up period.

COVID-19 Lockdown and Impact on 2-Year Weight Loss in a Bariatric Center.

Introduction: The COVID-19 pandemic has led to a worldwide lockdown, which affected physical exercise habits, as well as having a detrimental effect on psychological health and follow-up visits of patients submitted to bariatric surgery. The aim of this study was to evaluate the impact of COVID-19 lockdown on the 2-year weight loss of patients submitted to bariatric surgery in our center.

Methods: This was an observational study comparing the weight loss of patients who underwent bariatric surgery from January to March 2020 with a control group submitted to surgery between January and March 2017.

Efficacy, Toxicity, and Prognostic Factors of Re-treatment With [177Lu]Lu-DOTA-TATE in Patients With Progressing Neuroendocrine Tumors: The Experience of a Single Center.

Purpose: Peptide receptor radionuclide therapy (PRRT) is an effective and safe treatment of unresectable or metastatic, progressive neuroendocrine tumours (NETs). However, if progression occurs after the initial PRRT, treatment options remain limited. Our aim was to evaluate the efficacy and safety of a repeat Lutetium-[DOTA°,Tyr]octreotate ([Lu]Lu-DOTA-TATE) PRRT course in patients with progressive NET after the first [Lu]Lu-DOTA-TATE PRRT (peptide receptor radionuclide therapy first treatment (PRRT1)).

Cushing's Syndrome Behind Hypokalemia and Severe Infection: A Case Report.

Cushing's syndrome (CS) is a rare condition associated with increased morbidity and mortality. Complications derive from hypercortisolism and are mainly cardiovascular, infectious and thrombotic. Most manifestations are unspecific, and the diagnosis is frequently delayed and made only in the setting of complications.

Waist-to-Hip Ratio and Inflammatory Parameters Are Associated with Risk of Non-Alcoholic Fatty Liver Disease in Patients with Morbid Obesity.

Non-alcoholic fatty liver disease (NAFLD) is associated with several other metabolic disorders, which are typically pro-inflammatory states. Body fat content is an important marker of metabolic health and abdominal fat is associated with harmful cardiometabolic outcomes. We aimed to evaluate the association between the risk of NAFLD (through Fatty Liver Index (FLI), and BMI, AST/ALT ratio, and presence of diabetes (BARD)), and anthropometric parameters, predictors of metabolic status, in patients with morbid obesity, and to evaluate the association of FLI and BARD scores with pro-inflammatory markers.

Oral glucose tolerance testing at 1 h and 2 h: relationship with glucose and cardiometabolic parameters and agreement for pre-diabetes diagnosis in patients with morbid obesity.

Background: One hour plasma glucose concentration (1hPG) during an oral glucose tolerance test (OGTT) may be an alternative to 2-h plasma glucose concentration (2hPG) in the identification of individuals at increased risk of hyperglycaemia, although its role is not fully understood.

Aim: We aim to investigate the relationship of these measures with other glucose parameters, as well as their relationship with cardiometabolic risk markers and the level of agreement for prediabetes mellitus diagnosis, in a sample of patients with morbid obesity.

Methods: We retrospectively evaluated 656 patients with morbid obesity without diagnosed diabetes.

Virchow node of an unusual aetiology - the experience of a clinical case.

Background: The cause of adult adenomegalies may be defiant. On the other hand, ectopic thyroid is a rare condition that happens in every 1:100000 to 300,000 of healthy individuals. Here, we present a case report that joins these two clinical rare and defiant challenges.

Methotrexate Pneumonitis After a Low-Dose Medication Error: A Case Report.

Methotrexate is recommended as the first choice of standard drug therapy following the diagnosis of rheumatoid arthritis. Pneumonitis related to methotrexate is a serious, unpredictable adverse event that may become life-threatening. We reported a case of a 68-year-old woman with rheumatoid arthritis that misunderstood the directions for use and took methotrexate daily, instead of weekly, leading to hepatic, hematological, and pulmonary toxicity.

Adequate magnesium level as an associated factor of pre-diabetes and diabetes mellitus remission in patients with obesity submitted to bariatric surgery.

Bariatric surgery (BS) can lead to remission of type 2 diabetes mellitus (T2DM), however, the evidence on the influence of preoperative serum magnesium levels on this reversal is scarce. To study the influence of preoperative serum magnesium levels on the pre-T2DM and T2DM remission one year after BS. Retrospective study carried out among 1656 patients with obesity who underwent BS in the Centro Hospitalar Universitário São João.

Gut microbiota changes after metabolic surgery in adult diabetic patients with mild obesity: a randomised controlled trial.

Background: Roux-en-Y gastric bypass (RYGB) surgery is one of the most efficient procedures for the treatment of obesity, also improving metabolic and inflammatory status, in patients with mild obesity. The underlying mechanisms have not been fully understood, but gut microbiota is hypothesized to play a key role. Our aim was to evaluate the association between gut microbiota changes and anthropometric, metabolic and inflammatory profiles after metabolic surgery compared with medical therapy, in type 2 diabetic (T2DM) adults with mild obesity (BMI 30-35 kg/m).

Bariatric Surgery Impact on Cardiovascular Risk Factors: Is Age a Factor to Consider?

Introduction: Despite the abundance of data addressing the influence of patient's age on surgery-related complications, its impact on cardiometabolic outcomes following bariatric surgery has been overlooked.

Methods: Retrospective unicentric study of 1,728 obese patients who underwent bariatric surgery between January 2010 and June 2015. Patients were divided in 3 age groups, according to their age at surgery: ˂40 (n = 751), 40-59 (n = 879), and ≥60 years (n = 98).

Thyroid Function and the Risk of Non-Alcoholic Fatty Liver Disease in Morbid Obesity.

Background: An association between hypothyroidism and the risk of Non-alcoholic Fatty Liver Disease (NAFLD) has been suggested. This association remains to be elucidated in patients with morbid obesity.

Aim: To evaluate the association between thyroid function and parameters of liver function and hepatic scores in patients with morbid obesity.

Calcium Modulation, Anti-Oxidant and Anti-Inflammatory Effect of Skin Allergens Targeting the Nrf2 Signaling Pathway in Alzheimer's Disease Cellular Models.

Experimental evidence highlights nuclear factor (erythroid-derived 2)-like 2 (Nrf2) as a molecular target in Alzheimer's disease (AD). The well-known effect of electrophilic cysteine-reactive skin allergens on Nrf2-activation led to the hypothesis that these compounds could have a therapeutic role in AD. This was further supported by the neuroprotective activity of the skin allergen dimethyl fumarate (DMF), demonstrated in in vivo models of neurodegenerative diseases.

Which Factors Are Associated with a Higher Prevalence of Anemia Following Bariatric Surgery? Results from a Retrospective Study Involving 1999 Patients.

Introduction: Anemia in obese patients is common and multifactorial and is also a complication of bariatric surgery. The aim of this study is to establish which variables are associated with a higher prevalence of post-bariatric surgery anemia.

Methods: Retrospective cohort study involving 1999 patients submitted to bariatric surgery with a follow-up period of 4 years.

The Impact of Bariatric Surgery on Hepatic Function and Predictors of Liver Steatosis and Fibrosis.

Purpose: To evaluate the variation in parameters of hepatic function and in the scores Fatty Liver Index (FLI; predictor of hepatic steatosis) and BARD (BMI, AST/ALT ratio and DM, predictor of hepatic fibrosis), 1 year after bariatric surgery.

Material And Methods: This is a observational retrospective cohort study in patients with morbid obesity that underwent bariatric surgery in our centre. We used two linear regression models: (1) unadjusted and (2) adjusted for surgery type, sex, age, body mass index, diabetes, and dyslipidaemia.

Impact of Depression on Weight Variation after Bariatric Surgery: A Three-Year Observational Study.

Introduction: The association between obesity and depression has been repeatedly established. However, little is known about the impact that the diagnosis of depression before bariatric surgery (DDBS) may have on weight loss.

Objective: To evaluate the impact of DDBS on weight outcomes.

Variable Thresholds of Vitamin D Plasma Levels to Suppress PTH: the Effect of Weight and Bariatric Surgery.

Background: Serum 25-hydroxyvitamin D [25(OH)D] and parathormone (PTH) have an inverse relation. The 25(OH)D threshold required to maximally suppress PTH has been used as a marker of optimal vitamin D status. Obesity is associated with lower serum levels of 25(OH)D and higher levels of PTH; however, the relation between these hormones in this setting is not well established.
