Improvement in Muscle Strength and Metabolic Parameters Despite Muscle Mass Loss in the Initial Six Months After Bariatric Surgery.

Background: An aggravation in pre-existing sarcopenia or the onset of sarcopenia may occur in the scenario of extensive and fast weight loss in the initial months following bariatric surgery. The accurate identification of sarcopenia criteria and its metabolic repercussions is vital for its correct management. The aim of this study is to evaluate the correlation between the diagnosis criteria for sarcopenia and metabolic repercussions during the first 6 months following bariatric surgery.

Biliary cannulation with contrast and guide-wire versus exclusive guide-wire: A prospective, randomized, double-blind trial.

Background: The use of exclusive guide-wire cannulation (e-GW) instead of contrast injection reduces post-ERCP pancreatitis (PEP) and pre-cutting and increases cannulation rate. Herein, we intend to compare e-GW with the hybrid technique (GW-C and/or contrast injection).

Methods: Prospective single-center randomized comparative study, which included all patients referred to ERCP to our unit.

Endoscopic Biliary Large Balloon Dilation Lithotripsy for Giant and Impacted Stones Removal: A Western Series.

Background: Endoscopic removal of packed, large, or impacted stones, in which a basket cannot be deployed or is unable to grasp the stone(s), is challenging and inevitably leads to repeated procedures such as stent insertion and extra- or intracorporal lithotripsy. In this study, we describe the results of an alternative stone disintegration technique in a considerable series of patients using an esophageal/pyloric balloon for stone fragmentation or making working space in the bile duct to allow the deployment of the basket, a technique we call endoscopic biliary large balloon lithotripsy.

Methods: We retrieved data from 1,429 endoscopic retrograde cholangiopancreatographies (ERCPs) from 2 prospective trials performed between 2014 and 2019.

DNA repair and cell synthesis proteins: immunohistochemical expression and correlation with recurrence-regrowth in meningiomas.

Meningiomas are considered the second most common neoplasm of the central nervous system in adults. Most of them are benign with slow growth, frequent in women and with a high recurrence rate. In tumors, DNA error repair processes lose efficacy, providing mutagenesis and genomic instability.

Introduction: Axial skeleton arthropathy and osteoporotic vertebral fractures are common findings in acromegalic patients and can result in severe spinal deformity.

Objective: To investigate the presence of spinal fractures and deformities, sagittal imbalances, and spinopelvic compensatory mechanisms in acromegalics.

Patients And Methods: 58 patients with acromegaly from a referral neuroendocrinology center were prospectively evaluated by panoramic spine radiographs to detect the presence of fractures and scoliosis, to measure thoracic kyphosis, lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT) and sagittal vertical axis (SVA).

Impact of linked-color imaging on colorectal adenoma detection.

Background And Aims: Linked-color imaging (LCI) is a new technology that emphasizes changes in mucosal color by providing clearer and brighter images, thus allowing red and white areas to be visualized more clearly. We investigated whether LCI increases the detection of colorectal adenomas compared with white-light imaging (WLI) and blue-laser imaging (BLI)-bright.

Methods: Consecutive patients undergoing colonoscopy were randomized (1:1:1) into examination by WLI, BLI-bright, or LCI during withdrawal of the colonoscope.

PTTG overexpression in non-functioning pituitary adenomas: Correlation with invasiveness, female gender and younger age.

Background: Non-functioning pituitary adenomas (NFPA) are prevalent pituitary neoplasms. Because they do not present with hormonal hypersecretion, there is no marker that indicates regrowth or recurrence, as in other adenomas.

Objectives: Evaluate the immunohistochemical expression of PTTG, CD105 and Ki-67 and their relationships with age, gender, invasiveness, hormonal expression and regrowth or recurrence in the follow-up of NFPA operated and not submitted to radiotherapy.

EVALUATION OF TREATMENT OF CENTRAL HYPOTHYROIDISM VERSUS PRIMARY HYPOTHYROIDISM IN RELATION TO LEVOTHYROXINE REPLACEMENT DOSE.

The aim of this study was to evaluate levothyroxine (LT4) replacement daily doses in patients with central hypothyroidism (CeH) and compare them with those adequate for patients with primary hypothyroidism (P-HYPO). We included 53 patients with CeH and 57 with P-HYPO, matched by sex, age, weight, and body mass index, in the period of 1 year. At the time of inclusion, all presented a stable and adequate dose of LT4 for at least 3 months, considering as adequate the dose associated with normal thyroid-stimulating hormone (TSH) levels and free thyroxine (T4) in P-HYPO patients, and free T4 levels in CeH patients.
