alpha-1-Acid glycoprotein (AGP) is a glycoprotein that presents different forms in the same individual, depending on the amino acid sequence and/or on the carbohydrate distribution of each form. Changes in these two types of heterogeneities are related to pathophysiological states. The aim of this work is to study the possibility of comparing AGP samples in terms of their CIEF profiles, what would facilitate in a future to perform studies about the role of AGP as a disease marker. In the present study, the CIEF profiles of AGP samples purified from sera of healthy donors and of ovary cancer and lymphoma patients are qualitatively and quantitatively compared. To make possible the comparison of those electrophoretical profiles, reliable assignment of AGP peaks is necessary. A computer program developed in our laboratory is used to select the migration parameters that make possible an accurate assignment of AGP peaks. Percentages of correct assignment of AGP peaks using the migration time of each peak relative to the migration time of an internal standard close to 95% are achieved. After peak assignment, a different distribution of the area percentage of AGP forms is observed when comparing samples from diseased and healthy individuals, the most acidic AGP forms being present in a higher proportion in the samples from cancer patients. Although the number of samples studied is too low to get any clinical significance from these results, this work provides a way to study the role of AGP as a biomarker.

Effectiveness of a social cognition remediation intervention for patients with schizophrenia: a randomized-controlled study.

This randomized-controlled study evaluates the effectiveness of a newly developed social cognition rehabilitation intervention, the modified Social Cognition Individualized Activity Lab (mSoCIAL), in improving social cognition and clinical and functional outcomes of persons with schizophrenia recruited in two Italian sites: University of Campania "Luigi Vanvitelli" in Naples and ASST Fatebenefratelli-Sacco in Milan. mSoCIAL consists of a social cognitive training module focusing on different domains of social cognition and of a narrative enhancement module. We assessed changes in social cognition, clinical characteristics and functional variables in patients with schizophrenia who participated in 10 weekly sessions of mSoCIAL or received treatment as usual (TAU).

A total of 640 one-day-old Cobb 500 MV × Cobb 500 FF mixed broilers were randomly assigned to one of four experimental treatments with four replicates per treatment and 40 birds per replicate for 32 days. The treatments consisted of a basal diet (control group), basal diet + 0.02% zinc bacitracin (AGP group), basal diet + 0.

Background: Worldwide, approximately 2 million children younger than 15 years of age are infected with multidrug-resistant (MDR) , with MDR tuberculosis developing in approximately 30,000 annually. Evidence from randomized, controlled trials on tuberculosis preventive treatment in persons exposed to MDR tuberculosis is lacking.
Methods: In this community-based, multisite, double-blind, cluster-randomized, placebo-controlled trial in South Africa, we assessed the efficacy and safety of levofloxacin as preventive treatment in children with household exposure to an adult with bacteriologically confirmed MDR pulmonary tuberculosis.

Background: The value of patient and public involvement (PPI) during the earliest stages of clinical trial development, and prior to the award of substantive funding, is widely recognised. However, it is often under-resourced and PPI processes during this phase are rarely reported in detail. Having benefitted from seed funding to develop an international clinical trial proposal, we sought to describe and appraise PPI activities and processes that support pre-award co-development.

Background: Cardiac surgery-associated acute kidney injury (CSA-AKI) is a serious complication in patients undergoing cardiac surgery with extracorporeal circulation (ECC) that increases postoperative complications and mortality. CSA-AKI develops due to a combination of patient- and surgery-related risk factors that enhance renal ischemia-reperfusion injury. Sodium-glucose cotransporter 2 inhibitors (SGLT2i) such as empagliflozin reduce renal glucose reabsorption, improving tubulo-glomerular feedback, reducing inflammation and decreasing intraglomerular pressure.
