Background: Cardiac magnetic resonance (CMR) myocardial perfusion imaging has been suggested as a non-invasive alternative to pressure wire guided fractional flow reserve (FFR) in detecting haemodynamically significant obstructive coronary artery disease (CAD). The objective of this systematic review is to determine the diagnostic accuracy of CMR and to compare it to FFR.
Methods/design: A systematic review of diagnostic test accuracy of CMR and FFR will be conducted. Relevant English-language articles published before November 2013 in Medline, PubMed, EMBASE, Google scholar, Scopus and Cochrane databases will be identified. Relevant referenced articles from those selected will also be analysed. Articles describing diagnostic studies that compared CMR to FFR in patients with known or suspected coronary artery disease will be included. Two investigators will independently screen, assess quality and extract data from the selected articles. The Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool will be used to assess methodological quality. STATA 13 (the xtmelogit command) software will be used to calculate bivariate random effects models and estimate pooled sensitivity and specificity with 95% confidence intervals. Forests plots and summary receiver operating characteristics curves will also be generated. Sub-group pooled analyses using image quality of CMR (in terms of magnetic flux density - Tesla) and basis of analyses (coronary arterial territory vs. patients basis) at different FFR cutoffs (≤0.75 and ≤0.8) will also be performed.
Discussion: This systematic review will help to determine if CMR is an adequate alternative to FFR in the diagnosis of significant and obstructive CAD. We will also be able to assess diagnostic accuracy of specific types of CMR scan at different FFR cutoffs.
Systematic Review Registration: This systematic review had been registered at PROSPERO and the registration number is CRD42013006180.

Background: Epiphyllous bryophytes are a group of plants with complex adaptations to colonize the leaves of vascular plants and are considered one of the most specialized and sensitive groups to environmental changes. Despite their specificity and ecological importance, these plants represent a largely neglected group in relation to scientific research and ecological data. This lack of information directly affects our understanding of biodiversity patterns and compromises the conservation of this group in threatened ecosystems.

Objectives: As one of the most common complications of laryngopharyngeal reflux or gastroesophageal reflux disease, dental erosion presents a significant association with laryngopharyngeal reflux. This study aimed to elucidate the role of laryngopharyngeal reflux and gastroesophageal reflux disease on the severity and occurrence of dental erosion in adult populations.
Methods: A comprehensive search was performed in the databases of PubMed/MEDLINE, Web of Science, Cochrane Library, and Scopus for English literature published from July 1999 to June 2024.

The rapid development and deployment of mRNA and non-mRNA COVID-19 vaccines have played a pivotal role in mitigating the global pandemic. Despite their success in reducing severe disease outcomes, emerging concerns about cardiovascular complications have raised questions regarding their safety. This systematic review critically evaluates the evidence on the cardiovascular effects of COVID-19 vaccines, assessing both their protective and adverse impacts, while considering the challenges posed by the limited availability of randomized controlled trial (RCT) data on these rare adverse events.

Department of Internal Medicine, Aristotle University, Hypertension, Hypertension-24h ambulatory blood pressure monitoring center, Papageorgiou Hospital, Thessaloniki, Greece.
Purpose Of The Review: Τhe association between nocturnal blood pressure (BP) and alterations in the retinal microvasculature remains understudied, with few available studies to provide conflicting results. Therefore, we conducted a systematic review and meta-analysis to determine whether an association exists between retinal microvascular alterations and nocturnal BP patterns, determined by 24h ambulatory BP measurement.
Recent Findings: Our search concluded to 1002 patients (6 studies).
