Background: Rheumatoid arthritis (RA) is associated with an increase in cardiovascular (CV) risk. This issue maybe not only explained by a genetic component, as well as by the traditional CV risk factors, but also by an underestimation and undertreatment of concomitant CV comorbidities.Method: This was a retrospective matched-cohort analysis in the Italian RA real-world population based on the healthcare-administrative databases to assess the CV risk factors and incidence of CV events in comparison with the general population. Persistence and adherence to the CV therapy were also evaluated in

Introduction: In times when the term inclusion, rights of patients, and the patient as a subject in health care are used more often, the limited availability of written material or sign language interpreters at health services is still a key barrier to health services for people who are hearing-impaired. The aim of this study is to examine nurses’ knowledge of communication skills with hearing-impaired patients, their preferred methods, and the possibility of using translation services.

Ordering and protocolling CT scans after-hours from the emergency department (ED) at our institution previously required discussion between the ED physician and radiology resident, which led to workflow inefficiency. Our intervention consisted of creating an electronic list of CT requests that radiology residents would monitor. Radiology protocolled straightforward requests and contacted the ordering physician for more details when required. We aimed to improve workflow efficiency, increase provider satisfaction and reduce CT turnaround time without significantly affecting CT utilisation. Plan

Accumulating evidence suggests the potential use of chloroquine, an anti-malaria medication, as a neuroprotective agent. Moreover, several studies have reported that the endogenous opioids and nitric oxide (NO) may mediate the chloroquine’s effects. In the present study, effects of chloroquine on hyoscine-induced memory impairment were assessed. Furthermore, the possible involvements of opioids and NO were evaluated. Chloroquine was administered intraperitonially (i.p.) at doses of 0.1, 0.5, 1, 3, 10, and 20 mg/kg to hyoscine-treated (1mg/kg, i.p.) mice, and the spatial and fear memories were

The detoxification tissue, liver, plays a central role in maintaining circulating levels of glucose and lipid. Hypoglycemia and hypotriglyceridemia have been reported due to ecstasy abuse. Ghrelin is a 28-amino-acid peptide secreted predominantly from the stomach. It has been demonstrated that ghrelin has hepatoprotective effects and is able to increase blood glucose concentration.
