Confronted with a wide range of digital health tools (DHT), professionals and patients need guidance to use these tools correctly and optimize health management. In the fall of 2020, a DHT library developed by Quebec-based company TherAppX was implemented in 22 institutions. The library was designed to enable healthcare professionals to use DHT in clinical care.

Background: There is a growing trend concerning the use of information and communication technologies (ICT) for seeking health-related information such as information on medications and side effects. However, people looking online for health information cannot always judge the credibility of the information.

Objectives: This study aimed to describe patients' and pharmacists' experience using an asynchronous teleconsultation platform entitled "Ask Your Pharmacist" (AYP) and gather their perspectives and those of various healthcare and social services professionals providing primary care.

Searching the commercial Google Play Store and App Store is one of the most common strategies for discovering mobile applications for digital health, both among consumers and healthcare professionals. However, several studies have suggested a possible mismatch between this strategy and the objective of finding apps in physical and mental health that are both clinically relevant and reliable from a privacy standpoint. This study provides direct evidence of a gap between the five-star user rating system and expert ratings from a curated library of over 1,200 apps that cover both physical and mental health.

Background: An increasing number of pharmacists use technology and social media to connect with patients. However, such means may pose confidentiality issues and legal problems. To correct this situation, a platform of teleconsultation services provided by pharmacists, titled "Ask Your Pharmacist," was created in Quebec, Canada.

Objective: A reduction in lexical access is observed in normal aging and a few studies also showed that this ability is affected in individuals with subjective cognitive decline. Lexical access is also affected very early in mild cognitive impairment as well as in major neurocognitive disorders. The detection of word-finding difficulties in the earliest stages of pathological aging is particularly difficult because symptoms are often subtle or mild.

Objectives: Low levels of high-density lipoprotein (HDL) cholesterol are associated with an increased risk of acute myocardial infarction possibly through impaired endothelial atheroprotection and decreased nitric oxide (NO) bioavailability. Asymmetric dimethylarginine (ADMA) mediates endothelial function by inhibiting nitric oxide synthase activity. In patients with acute myocardial infarction, we investigated the relationship between serum levels of HDL and ADMA.

Spine degeneration is a pathology that will affect 80% of the population. Since the intervertebral disks play an important role in transmitting loads through the spine, the aim of this study was to evaluate the biomechanical impact of disk properties on the load carried by healthy (Thompson grade I) and degenerated (Thompson grades III and IV) disks. A three-dimensional parametric poroelastic finite element model of the L4/L5 motion segment was developed.

Purpose: To investigate the different treatment strategies in France and the direct costs for patients with newly diagnosed primary open-angle glaucoma or ocular hypertension who have started treatment with beta-blockers, and to estimate the total direct cost for two years of treat.

Material: and methods: We analyzed 225 medical charts retrospective in eleven academically and office-based centers in France over the first two years after diagnosis. Standard costs for each resource in current medical practice were determined from the French Social Security perspective.

Case report is a 75-year old woman who presented an unexplained febrile encephalopathy with diffuse myoclonic jerks and a gout's polyarthritis. None of these etiologies was found: infectious, toxic, vascular, metabolic, hormonal, immunologic. The spectacular effect on neurologic symptoms of a treatment by colchicine alone lead us to consider that gout encephalopathy probably exists.

[Travelers' diarrhea].

Rev Prat

January 1996

Up to fifty per cent of travellers going from temperate countries to tropical or subtropical countries present a diarrhoea. Enterotoxigenic Escherichia coli remain the most frequent bacterial cause, being identified in 40 to 70% of cases. Laboratory investigations are reserved to grave or protracted cases or those which resist to empirical therapy.

Five adults had inflammatory rheumatic disorders 6 to 20 years before the diagnosis of coeliac disease. It is known that joint inflammation occurs in certain patients with adult coeliac sprue who develop either a specific inflammatory rheumatic disease or an atypical progressive polyarthropathy, sometimes as the first manifestation of the intestinal disorder. The diagnosis of adult coeliac sprue should be entertained in these cases even in absence of major digestive disorders or malabsorption.
