Exercise restriction is a nonpharmacological treatment of pericarditis that could reduce symptoms by slowing heart rate (HR). Beta-blockers allow pharmacological control of HR. Aim of this paper is to explore the possible efficacy of beta-blockers to improve control of symptoms in patients with pericarditis. We analyzed consecutive cases with pericarditis referred to our center. Beta-blockers were prescribed on top of standard anti-inflammatory therapy in symptomatic patients (chest pain and palpitations) with rest HR>75 beats/min. The primary end point was the persistence of pericardial pain at 3 weeks. The secondary end point was the occurrence of recurrent pericarditis at 18 months. Propensity score matching was used to generate 2 cohorts of 101 patients with and without beta-blockers with balanced baseline features. A clinical and echocardiographic follow-up was performed at 3 weeks, 1, 3, 6 months and then every 12 months. A total of 347 patients (mean age 53 years, 58% females, 48% with a recurrence, 81% with idiopathic/viral etiology) were included. Among them, 128 patients (36.9%) were treated with beta-blockers. Peak C-reactive protein values were correlated with heart rate on first observation (r=0.48, p less then 0.001). Using propensity-score matched cohorts, patients treated with beta-blockers had a lower frequency of symptoms persistence at 3 weeks (respectively 4% vs. 14%; p = 0.024) and a trend towards a reduction of recurrences at 18 months (p = 0.069). In conclusion the use of beta-blockers on top of standard anti-inflammatory therapies was associated with improved symptom control.Genetics are known to be a significant risk factor for drug abuse. In human populations, the single nucleotide polymorphism (SNP) D398N in the gene CHRNA5 has been associated with addiction to nicotine, opioids, cocaine, and alcohol. In this paper, we review findings from studies in humans, rodent models, and cell lines and provide evidence that collectively suggests that the Chrna5 SNP broadly influences the response to drugs of abuse in a manner that is not substance-specific. This finding has important implications for our understanding of the role of the cholinergic system in reward and addiction vulnerability. This article is part of the special issue on 'Vulnerabilities to Substance Abuse.'Carbohydrate-based materials offer exciting opportunities for drug delivery. They present readily available, biocompatible components for the construction of macromolecular systems which can be loaded with cargo, and can enable targeting of a payload to particular cell types through carbohydrate recognition events established in biological systems. These systems can additionally be engineered to respond to environmental stimuli, enabling triggered release of payload, to encompass multiple modes of therapeutic action, or to simultaneously fulfil a secondary function such as enabling imaging of target tissue. Here, we will explore the use of glycomacromolecules to deliver therapeutic benefits to address key health challenges, and suggest future directions for development of next-generation systems.The COVID-19 pandemic is a serious threat to global health and the global economy. The ongoing race to develop a safe and efficacious vaccine to prevent infection by SARS-CoV-2, the causative agent for COVID-19, highlights the importance of vaccination to combat infectious pathogens. Ivacaftor purchase The highly accessible cutaneous microenvironment is an ideal target for vaccination since the skin harbors a high density of antigen-presenting cells and immune accessory cells with broad innate immune functions. Microarray patches (MAPs) are an attractive intracutaneous biocargo delivery system that enables safe, reproducible, and controlled administration of vaccine components (antigens, with or without adjuvants) to defined skin microenvironments. This review describes the structure of the SARS-CoV-2 virus and relevant antigenic targets for vaccination, summarizes key concepts of skin immunobiology in the context of prophylactic immunization, and presents an overview of MAP-mediated cutaneous vaccine delivery. Concluding remarks on MAP-based skin immunization are provided to contribute to the rational development of safe and effective MAP-delivered vaccines against emerging infectious diseases, including COVID-19.Localized or topical administration of drugs may be considered as a potential approach for overcoming the problems caused by the various biological barriers encountered in drug delivery. The combination of using localized administration routes and delivering drugs in nanoparticulate formulations, such as liposomes, may have additional advantages. Such advantages include prolonged retention of high drug loads at the site of action and controlled release of the drug, ensuring prolonged therapeutic effect; decreased potential for side-effects and toxicity (due to the high topical concentrations of drugs); and increased protection of drugs from possible harsh environments at the site of action. The use of targeted liposomal formulations may further potentiate any acquired therapeutic advantages. In this review we present the most advanced cases of localized delivery of liposomal formulations of drugs, which have been investigated pre-clinically and clinically in the last ten years, together with the reported therapeutic advantages, in each case.

This study aimed to assess the serial changes in de novo coronary lesions, including acute coronary syndrome (ACS), treated with a drug-coated balloon (DCB).

In this retrospective single-center study, the intravascular changes in patients with de novo lesions treated with DCB were evaluated with serial intravascular ultrasound (IVUS) pre-procedure, post-procedure, and at follow-up. A two-dimensional IVUS measurement was performed with slices at 1mm intervals in the treated lesion.

This study comprised 40 lesions, including 27 lesions with stable angina pectoris (SAP) and 13 ACS. IVUS showed that the median vessel and lumen area increased significantly from pre-procedure to post-procedure and from post-procedure to follow-up. The median plaque area decreased significantly from pre-procedure to post-procedure and follow-up. The IVUS between ACS and SAP demonstrated that the total vessel volume and the total lumen volume increased, and the total atheroma volume decreased significantly from pre- to follow-up in both groups.
