Acute rate control in atrial fibrillation: an urgent need for the clinician.

Rate and rhythm control are still considered equivalent strategies for symptom control using the Atrial Fibrillation Better Care algorithm recommended by the recent atrial fibrillation guideline. In acute situations or critically ill patients, a personalized approach should be used for rapid rhythm or rate control. Even though electrical cardioversion is generally indicated in haemodynamically unstable patients or for rapid effective rhythm control in critically ill patients, this is not always possible due to the high percentage of failure or relapses in such patients. Rate control remains the background therapy for all these patients, and often rapid rate control is mandatory. Short and rapid-onset-acting beta-blockers are the most suitable drugs for acute rate control. Esmolol was the classical example; however, landiolol a newer very selective beta-blocker, recently included in the European atrial fibrillation guideline, has a more favourable pharmacokinetic and pharmacodynamic profile with less haemodynamic interference and is better appropriate for critically ill patients.

Shared Molecular Targets in Parkinson's Disease and Arterial Hypertension: A Systematic Review.

(1) Background: Parkinson's disease and arterial hypertension are likely to coexist in the elderly, with possible bidirectional interactions. We aimed to assess the role of antihypertensive agents in PD emergence and/or progression. (2) We performed a systematic search on the PubMed database. Studies enrolling patients with Parkinson's disease who underwent treatment with drugs pertaining to one of the major antihypertensive drug classes (ß-blockers, diuretics, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers and calcium-channel blockers) prior to or after the diagnosis of parkinsonism were scrutinized. We divided the outcome into two categories: neuroprotective and disease-modifying effect. (3) We included 20 studies in the qualitative synthesis, out of which the majority were observational studies, with only one randomized controlled trial. There are conflicting results regarding the effect of antihypertensive drugs on Parkinson's disease pathogenesis, mainly because of heterogeneous protocols and population. (4) Conclusions: There is low quality evidence that antihypertensive agents might be potential therapeutic targets in Parkinson's disease, but this hypothesis needs further testing.

The prevalence and the impact of sarcopenia in digestive cancers. A systematic review.

Introduction: Sarcopenia is characterized by a decrease in skeletal muscle mass, associated with low muscle strength and/or poor physical performance. Assessing the prevalence of sarcopenia among digestive cancers and establishing the impact that sarcopenia has on the postoperative evolution of digestive tumors may be a central pillar in improving postoperative outcomes by caring for perioperative sarcopenia. This brief review aimed to evaluate the prevalence of sarcopenia in digestive cancer patients. Method and materials: PubMed database was searched for "sarcopenia" AND "digestive cancers" from January 1st, 2010, through September 30th, 2020. PRISMA guideline was used for this systematic review. After the selection process, 31 complete studies were included in our review. Assessment of sarcopenia diagnosis for the studies included in this systematic review was based on a computed tomographic calculation of the skeletal muscle index at the third lumbar vertebra. Results: Among a total of 11,651 patients with digestive cancers, the prevalence of sarcopenia was 43.68%. The highest prevalence of sarcopenic patients was in esophageal (70.4%) and hepatic (60.3%) cancer, following by biliary tract (49.3%), pancreatic (45.70%), colorectal (42.83%) cancer, and gastric cancer (32.05%) with the lowest prevalence. The results of the studies conducted by now regarding the prevalence of sarcopenia in digestive cancers and its relevance in the evolution of these cancers are discordant and uneven. Some studies show that the presence of sarcopenia in patients with digestive cancers is associated with an increased rate of postoperative complications, increased toxicity of chemotherapeutics and increased mortality. Other studies do not find sarcopenia as an independent risk factor associated with negative consequences in the course of patients with digestive cancers. Conclusions: Sarcopenia is prevalent in digestive cancers. There is still no consensus about the impact of sarcopenia on the treatment of digestive cancers. Further studies are needed to evaluate the real consequences of sarcopenia in digestive cancers..

Blood Pressure Patterns in Patients with Parkinson's Disease: A Systematic Review.

(1) Background: Cardiovascular autonomic dysfunction is a non-motor feature in Parkinson's disease with negative impact on functionality and life expectancy, prompting early detection and proper management. We aimed to describe the blood pressure patterns reported in patients with Parkinson's disease, as measured by 24-h ambulatory blood pressure monitoring. (2) Methods: We conducted a systematic search on the PubMed database. Studies enrolling patients with Parkinson's disease undergoing 24-h ambulatory blood pressure monitoring were included. Data regarding study population, Parkinson's disease course, vasoactive drugs, blood pressure profiles, and measurements were recorded. (3) Results: The search identified 172 studies. Forty studies eventually fulfilled the inclusion criteria, with 3090 patients enrolled. Abnormal blood pressure profiles were commonly encountered: high blood pressure in 38.13% of patients (938/2460), orthostatic hypotension in 38.68% (941/2433), supine hypertension in 27.76% (445/1603) and nocturnal hypertension in 38.91% (737/1894). Dipping status was also altered often, 40.46% of patients (477/1179) being reverse dippers and 35.67% (310/869) reduced dippers. All these patterns were correlated with negative clinical and imaging outcomes. (4) Conclusion: Patients with Parkinson's disease have significantly altered blood pressure patterns that carry a negative prognosis. Ambulatory blood pressure monitoring should be validated as a biomarker of PD-associated cardiovascular dysautonomia and a tool for assisting therapeutic interventions.

Stroke Prevention in Atrial Fibrillation - The Use of NOACs in Everyday Clinical Practice.

Non-antivitamin K oral anticoagulants (NOACs) have recently emerged as a new class of antithrombotic drugs. Four large-scale, randomised controlled trials (RCT) accredited dabigatran, rivaroxaban and edoxaban with evident advantages for stroke prevention in atrial fibrillation (AF) compared with warfarin. The superiority concerns not only the manageability but also the antithrombotic efficacy and safety. Aspects of real-life clinical experience with NOAC for stroke prevention in AF are analysed in an attempt to underline some practical differences. If at present the individualisation of the NOAC class drugs is still a subject of debate it is probable that in the near future we will be able to adapt the drug and dosages to individual patient's profile.
