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.
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.

This study aimed to evaluate maximum voluntary contractions of the pelvic floor muscle in sportswomen and verify the association with leg stiffness and muscle power, both maximal and submaximal.
Methods: The sample consisted of 41 sportswomen between 18 and 42 years of age.
Introduction: Bariatric surgery (BS) is the most effective therapeutic approach to obesity. It is associated with great gastrointestinal anatomic changes, predisposing the patients to altered nutrient absorption that impacts phosphocalcium metabolism. This study aimed to clarify the prevalence of secondary hyperparathyroidism (SHPT) and its predictors in patients submitted to BS.

- * Conducted between 2010 and 2018, the study included 1,124 patients, revealing that a significant portion had low vitamin D levels, linked to higher body measurements and health risks like hypertension.
- * Results suggest that low vitamin D is associated with a higher risk of liver fat accumulation, implying that improving vitamin D levels could aid in managing non-alcoholic fatty liver disease in these individuals.
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).
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.
Which Factors Are Associated with a Higher Prevalence of Anemia Following Bariatric Surgery? Results from a Retrospective Study Involving 1999 Patients.

September 2020
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.
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.
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.
Objectives: To evaluate Maximum Voluntary Contraction (MVC) of the Pelvic Floor Muscles (PFM) in sportswomen, to observe the urinary symptoms and their impact on the Quality of Life (QoL).
Design: Observational cross-sectional study.
Setting: Gyms and teams in the North of Portugal.
The aim of this study was to investigate the effects of pelvic floor muscles training in elite female volleyball athletes and whether it is an effective therapy for stress urinary incontinence. Fourteen athletes, both continent and incontinent, between 18 and 30 years of age, were randomly assigned to an experimental group or a control group. The experimental group received a protocol for pelvic floor muscle training for 4 months.

The aim of this study was to adapt and validate the King's Health Questionnaire (KHQ) in women with UI to Portugal.
Methods: For the adaptation, a multistep forward-back translation protocol was used.
Introduction And Hypothesis: Urinary incontinence (UI) is prevalent in sport students. We hypothesized that pelvic floor muscle training (PFMT) can improve pelvic floor muscle (PFM) strength and symptoms of UI in this group of physically active women.
Methods: Sixteen sport students with UI participated in this pre-post test pilot study.
