Gelsolin is an actin filament-severing and -capping protein that has profound effects on actin filament organization and assembly. It is activated by Ca2+ and inhibited by polyphosphoinositides (PPI). We have previously shown that PPI inhibit actin filament severing by the amino-terminal half of gelsolin and hypothesized that this is mediated through inhibition of actin filament side binding (b...

OBJECTIVES To evaluate the appropriateness of proton pump inhibitor (PPI) prescribing by conducting an audit of medical inpatients against recommended guidelines. DESIGN Questionnaire-based study. All medical wards were audited and different information was documented by patients' medical records review (both hospital visit notes and general practitioner's letters) and short interview, where ...

Background Proton pump inhibitors (PPIs) are among the most commonly prescribed medications in clinical practice. PPI use has been associated with the development of community-acquired pneumonia. With a reported prevalence of gastroesophageal reflux disease (GERD) and PPI use that is higher than the general population, patients with cystic fibrosis (CF) are particularly vulnerable to PPI advers...

The effect of feeding diets containing either spray-dried porcine plasma (SDPP) or pea protein-isolate (PPI) supplemented with either egg yolk antibodies (EYA) from hens immunized with enterotoxigenic Escherichia coli (ETEC) (K88 and F18) antigens, ZnO, fumaric acid (FA), or carbadox (AB) on pig performance, incidence of scours, and gut morphology was studied in a 14-d experiment. Ninety 10-d-o...

Results We interviewed 21 chief investigators, 10 trial managers and 17 PPI contributors from 28 trials. Over half the informants indicted that PPI had made a difference, influencing either an aspect of a trial, or how trialists felt about a trial. Informants described how PPI’s impact depended on the quality of chief investigators’ goals and plans for PPI, the quality of relationships between ...

BACKGROUND The rate of significant conduction disturbances requiring permanent pacemaker implantation (PPI) following surgical aortic valve replacement (AVR) is 2-8%. Transcatheter aortic valve implantation (TAVI) is an alternative management approach in patients with severe aortic stenosis who are not considered candidates for AVR. The TAVI using the CoreValve (CV) bioprosthesis is associated ...

PURPOSE The present study aimed to assess the cost effectiveness of concomitant proton pump inhibitor (PPI) treatment in low-dose acetylsalicylic acid (LDASA) users at risk of upper gastrointestinal (UGI) adverse effects as compared with no PPI co-medication with attention to the age-dependent influence of PPI-induced adverse effects. METHODS We used a Markov model to compare the strategy of ...

BACKGROUND Proton-pump inhibitors (PPIs) are among the most frequently prescribed medications. Community-acquired pneumonia (CAP) is a common cause of morbidity, mortality and healthcare spending. Some studies suggest an increased risk of CAP among PPI users. We conducted a systematic review and meta-analysis to determine the association between outpatient PPI therapy and risk of CAP in adults....

Patient and public involvement (PPI) has been recognized internationally. In England, NHS policies have increasingly emphasized the importance of patient-centered services, but limited evidence exists about the implementation of PPI policies and strategies within organizations. Few studies have explored health professionals’ perceptions of PPI and comparatively little is known about the experie...
