ReviewThe ESC 2019 CCS guidelines: Have we left our patients and scientific evidence behind?
The ESC CCS 2019 guidelines recognize that successful management of anginal symptoms relies on effective therapy tailored to individual patient characteristics but do not provide any specific advice or clarity on how to utilize pharmacotherapy in order to achieve these goals. In this review, we are going to summarize and discuss the main points of disagreement.

ReviewProton pump inhibitors and cardiovascular adverse effects: Real or surreal worries?
Proton pump inhibitors (PPIs) are among the most widely prescribed agents, either for treatment or prophylaxis of gastrointestinal (GI) disease, that are often administered for prolonged or chronic use. Patients with cardiovascular (CV) disease frequently receive PPIs for prophylaxis against GI bleeding due to common use of antithrombotic drugs. Over the last several years there is a growing number of reports associating chronic PPI use with a variety of serious CV and non-CV adverse effects. ⋯ As the indications for prolonged, particularly lifelong, prophylactic use of PPIs are not compelling and in the light of evidence of serious CV and other adverse effects, clinicians have to reconsider such long-term use of these drugs. Importantly, histamine 2 blockers have not been found to be associated with increased CV risk and thus may be an alternative therapeutic option in certain patients. These issues are amply discussed together with the potential mechanisms of these pleiotropic and off-target effects of PPIs, which are also depicted in an illustrative schema; data are also presented on differential effects of specific agents involved, alternative modes of therapy available, and relevant current guidelines on this issue.

Review Meta AnalysisPrevalence of gastrointestinal malignancy in iron deficiency without anaemia: A systematic review and meta-analysis.
Iron deficiency anaemia is associated with gastrointestinal (GI) malignancy and is an indication for GI investigations. However, the relevance of iron deficiency without anaemia (IDWA) and the underlying risks of GI malignancy are uncertain. Therefore, the aim of this study was to estimate the prevalence of GI malignancy in patients with IDWA overall and in clinically relevant subgroups. ⋯ Overall, IDWA is associated with a low risk of GI malignancy. Older patients and non-screening populations are at elevated risk and require GI investigations. Those not in these subgroups have a lower risk of GI malignancy and may wish to be monitored following discussion of the risk and potential benefits of GI investigations.

Estimating static kidney function accurately and detecting changes in kidney function in a timely fashion are challenging but critically important tasks. Serum creatinine is the most widely used functional biomarker of the kidney. However, its use is associated with substantial shortcomings. ⋯ In this review, the pathways involved in creatinine generation and metabolism as well as the techniques involved in measuring creatinine concentrations are discussed. This allows for the discussion of the value and pitfalls in using creatinine as a marker of kidney function. In addition, information regarding alternative functional biomarkers of the kidney is provided.
