Catheter probe extraductal ultrasound (EDUS) exploration of the common bile duct is safe in elderly patients with suspicion of choledocholithiasis after distal gastrectomy

Purpose: Post-surgical upper gastrointestinal anatomy may hamper a complete bilio-pancreatic evaluation with a standard echoendoscope. The aim of this study was to assess the role of catheter probe extraductal ultrasound (EDUS) for the evaluation of the common bile duct (CBD) in patients who are status post-gastric surgery and who are suspected of having choledocholithiasis. Methods: We retrospectively analyzed patients with a prior history of gastric surgery, who underwent EDUS for a suspicion of CBD obstruction. For each patient, technical success, accuracy, and safety were recorded. In case of a positive finding of CBD stones, endoscopic retrograde cholangiopancreatography (ERCP) was performed. In case of other findings or a negative EDUS, computed tomography or magnetic resonance cholangiopancreatography (MRCP) was performed as appropriate. Results: EDUS was technically successful in all the 11 patients with a Billroth II gastrectomy, while it failed in all the 5 patients with Roux-en-Y gastric surgery. EDUS accuracy was 100% (3 true-positive and 8 true-negative cases). CBD stones, confirmed and successfully extracted at ERCP, were found in two patients, while in one patient EDUS showed a CBD stenosis that was treated with a plastic stent during ERCP; computed tomography at follow-up was negative for cancer. EDUS was correctly negative in 8 patients, as confirmed by MRCP. Conclusions: EDUS may represent an accurate and safe alternative to standard endoscopic ultrasonography and MRCP for the detection of CBD stones in elderly patients who are status post-Billroth II gastric surgery

Methods of evaluation of microvascular structure: state of the art

Cardiovascular diseases represent the leading cause of death in Western Countries. Among them, a key role is played by arterial hypertension, which causes macro- and microvascular alterations. Specifically, hypertension is associated with structural alterations in the microvessels, such as an increased ratio of the tunica media thickness to internal lumen (M/L ratio) in small resistance arteries and a reduction of capillary density. In order to evaluate the small resistance artery structure, the direct measurements of M/L ratio through wire or pressure micromyography has been considered the gold-standard method. Despite the availability of convincing evidence about the prognostic relevance of the M/L ratio, the invasiveness of these methods has limited its implementation in the daily clinical practice. Therefore, non-invasive techniques have been developed to evaluate microvascular morphology, particularly in the retina, since it is perhaps the most accessible microvasculature. Scanner laser Doppler flowmetry (SLDF) and adaptive optics (AO) represent the most promising approaches for the evaluation of morphological characteristics of retinal arterioles, in particular for the measurement of their wall-to-lumen ratio (W/L ratio). The possibility to evaluate microvascular morphology by non-invasive techniques represents a major clinical advancement, with possibly favorable implications in research and in stratification of cardiovascular risk. In this review we will address the different methods to investigate the microcirculation as well as their clinical usefulness

The Italian version of the Brief Assessment of Cognition in Affective Disorders: performance of patients with bipolar disorder and healthy controls

Objectives: Cognitive deficits in Bipolar Disorder (BD) are significant enough to have an impact on daily functioning. Therefore, appropriate tools must be used to improve our understanding of the nature and severity of cognitive deficits in BD. In this study, we aimed to compare the cognitive profiles of patients with BD and healthy controls (HC) applying the Italian version of the Brief Assessment of Cognition in Affective Disorders (BAC-A). Methods: This cross-sectional study included 127 patients with BD and 134 HC. The participants' cognitive profiles were evaluated using the Italian version of the BAC-A, which assesses verbal memory, working memory, motor speed, verbal fluency, attention &amp; processing speed, executive functions, and two new measures of affective processing. The BAC-A raw scores were corrected using the normative data for the Italian population. In addition, we explored whether intelligence quotient (IQ) and specific clinical variables would predict the BAC-A affective, non-affective, and total composite scores of patients with BD and HC. Results: HC performed better than patients with BD in all BAC-A subtests (all p < .001), except for subtests of the Affective Interference Test. (p ≥ .05). The effect sizes varied in magnitude and ranged between d = 0.02 and d = 1.27. In patients with BD, lower BAC-A composite scores were predicted by a higher number of hospitalizations. There was a significant association between IQ and BAC-A composite scores in both bipolar patients and HC. Conclusions: The Italian BAC-A is sensitive to the cognitive impairments of patients with BD in both affective and non-affective cognitive domains

Microvascular Density and Circulating Endothelial Progenitor Cells Before and After Treatment with Incretin Mimetics in Diabetic Patients

Glucagon-like peptide 1-receptor agonists (incretin mimetics) and dipeptidyl peptidase-4 inhibitors (incretin enhancers) have been recently introduced in the treatment of diabetes mellitus. In particular, incretin mimetics seems to have ancillary antioxidant/antinflammatory properties that might be involved in endothelial protection

The brief assessment of cognition in affective disorders: Normative data for the Italian population

BACKGROUND: To date there are no validated tests in Italian to assess cognitive functions in Bipolar Disorder. Therefore, this study aimed to provide normative data for the Italian version of the Brief Assessment of Cognition in Affective Disorders (BAC-A), a battery targeting neuro- and affective-cognition in affective disorders. METHODS: Data were collected from 228 healthy participants (age range: 18-67; mean age: 34.68 \ub1 12.15 years) across eight recruiting sites. The influence of age, sex and education was measured and adjusted for using multivariate stepwise regression models. Normative values were established by means of the Equivalent Score approach. RESULTS: Most of the BAC-A subtests showed patterns of association with age (inversely associated with overall cognitive performance), education (positively associated with Verbal Memory and Fluency, Digit Sequencing and Affective Processing subtests) and sex (females performed better than males in the Affective Interference Test but worse in the Emotion Inhibition Task, Digit Sequencing and Tower of London). LIMITATIONS: The sample size was not sufficiently large for developing stratified norms, using 10-years ranges. Moreover, the participants included in the study were, on average, highly educated. CONCLUSIONS: The normative data of the BAC-A provided in this study can serve as a cognitive functioning reference for Italian-speaking participants within the age range of the study sample. This can increase the applicability of this test in both clinical and research settings. The reliability and validity of the Italian BAC-A need to be further investigated
