Oral anticoagulants: Interventional pharmaceutical study with reminder of good practices, and iatrogenic impact.

Objectives: Study of the impact of geriatricians' training on the improvement of their prescribing practices, and comparison of iatrogenesis between the two classes of oral anticoagulants.

Material And Methods: Before/after and here/there comparison between a trained prescribers group and a control group, before and after the pharmacist intervention, with comparison of the iatrogenesis of two oral anticoagulant classes. Patients in the acute and post-acute geriatric departments treated with a vitamin K antagonist or a direct oral anticoagulant were included.

Acceptability in the Older Population: The Importance of an Appropriate Tablet Size.

Presenting many advantages, solid oral dosage forms (SODFs) are widely manufactured and frequently prescribed in older populations regardless of the specific characteristics of patients. Commonly, patients with dysphagia (swallowing disorders) experience difficulties taking SODFs, which may lead to non-adherence or misuse. SODF characteristics (e.

Acceptability of oral liquid pharmaceutical products in older adults: palatability and swallowability issues.

Background: In institutional care, oral liquid pharmaceutical products are widely prescribed for older patients, especially for those with swallowing disorders. As medicines acceptability is a key factor for compliance in the older population, this study investigated the acceptability of oral liquid pharmaceutical products in this targeted population.

Methods: An observational, multicenter, prospective study was conducted in eight geriatric hospitals and eight nursing homes in France.

Sex Differences in Medicine Acceptability: A New Factor to Be Considered in Medicine Formulation.

Palatability is a recognized driver of medicine acceptability in pediatrics but deemed less relevant in older populations due to sensory decline. Preliminary findings from an observational study implicated palatability problems with one Alzheimer's medicine. Among 1517 observer reports combining multiple measures on medicines uses in patients aged over 64, we focused on two original formulations of memantine (Ebixa, tablets ( = 25) and oral solution ( = 60)).

A Decision Support Tool Facilitating Medicine Design for Optimal Acceptability in The Older Population.

Purpose: Medicine acceptability, which is of the utmost importance for vulnerable patients' adherence, is driven by both user and product characteristics. Herein, a novel multivariate approach integrating the many aspects of acceptability is used to discriminate positively and negatively accepted medicines in the older population.

Methods: An observational study was carried out in eight hospitals and eight nursing homes to collect a large set of real-life data on medicines uses in older patients (≥65 years).

[Securing the therapy management during the leave permissions for the elderly patients].

Leave permission can be granted over a limited period of hospitalisation during which the patient can return home under the responsibility of the hospital. Despite its frequency, this practice is not evaluated in terms of maintaining the security of medication. This complex process involves several actors, processes and locations.

Orocecal transit time in humans assessed by sulfapyridine appearance in saliva after sulfasalazine intake.

Purpose: We propose a noninvasive method for the measurement of orocecal transit time assessed by the sulfapyridine appearance time in saliva after ingestion of sulfasalazine.

Method: In 12 healthy volunteers, we studied the correlation between plasma and saliva sulfapyridine appearance times and then the sulfapyridine appearance times in saliva under various experimental conditions to assess the reproducibility, the effects of meals, and the role of the formulation, and the effects of gastrointestinal kinetic drugs.

Results: The correlation between saliva and plasma sulfapyridine appearance times was strong (r = 0.

Relationships between fat and plasma androstenone and plasma testosterone in fatty and lean young boars following castration.

The effect of weight of fatty tissue on fat and plasma androstenone and on plasma testosterone relationships was studied in the young boar following castration. For this purpose, 9 boars were castrated at 175 days of age, plasma steroid levels were determined daily up to 10 days after orchidectomy and fat androstenone concentration was measured 1, 3, 6, 10 and 15 days after castration. The results show that the apparent half-life of stored androstenone is very variable between boars (range: 4 to 14 days) and do not depend on the weight of fatty tissue.

Relationships between fat and plasma androstenone and plasma testosterone in fatty and lean young boars during growth and after hCG stimulation.

The effect of weight of fatty tissue on fat and plasma androstenone and on plasma testosterone relationships in the young boar was studied. For this purpose, hCG stimulation of steroid testicular production was performed in 12 boars and fat androstenone concentration subsequently measured. In addition plasma androstenone and testosterone were determined in 8 of them, previously cannulated.

Bacterial formation of omega-muricholic acid in rats.

In the feces of conventional rats, the amount of omega-muricholic and hyodeoxycholic acids vary according to the diet. To understand this phenomenon, we investigated the bacterial formation of these bile acids. The present paper reports the first isolation, from conventional rat feces, of a strain of Clostridium group III which transforms beta-muricholic acid, the main bile acid in germfree rats, into omega-muricholic acid.

[Formation of omega-muricholic acid and fecal excretion of biliary acids in rats].

Two groups of Rats which were fed the same diet, excreted fecal bile acids of different patterns: in one group, the feces contained a large amount of omega-muricholic acid and very little hydrodeoxycholic acid; in the other group the reversed composition was observed. The first group excreted more total bile acids than the second. This observation suggests that the formation of a large amount of omega-muricholic acid results in an increase in total bile acid fecal excretion.
