RESUMO

Aprocitentan is a novel, oral, dual endothelin receptor antagonist (ERA) in development in difficult-to-control hypertension. As fluid retention and edema are concerns with ERAs, we investigated whether aprocitentan causes weight gain in healthy subjects on a high sodium diet and explored potential mechanisms if occurring. This double-blind, randomized, placebo-controlled, crossover study enrolled 28 subjects. Three doses of aprocitentan (10, 25, or 50 mg/day for 9 days) were compared with placebo. Increases in body weight were observed with aprocitentan (placebo-corrected mean weight gains [90% confidence interval]) of 0.43 [0.05-0.80], 0.77 [0.03-1.51], and 0.83 [0.33-1.32] kg at 10 mg, 25 mg, and 50 mg, respectively. Decreases in hemoglobin and uric acid were observed. Plasma volume increased at most by 5.5% without dose-response relationship. Urinary sodium excretion decreased at 10 mg and 25 mg but not at 50 mg. Therefore, aprocitentan produced moderate weight increases in healthy subjects on high sodium diet, without obvious sodium retention.

RESUMO

Thyroid nodules are a very common problem whose prevalence increases with age. When treatment is considered, surgical excision is traditionally the first choice, except in the case of hyperfunctioning nodules, where treatment with radioactive iodine plays a major role. In recent years, there has been increasing experience in the thermal ablation of thyroid nodules by radiofrequency, with very encouraging results. This article aims to discuss the role of radiofrequency thermal ablation in the management of benign thyroid nodules by reviewing the indications, adverse effects and limitations of this method.


Les nodules thyroïdiens sont un problème très fréquent dont la prévalence augmente avec l'âge. Lorsqu'un traitement est envisagé, l'excision chirurgicale occupe jusqu'à présent la première place, sauf dans le cas des nodules hyperfonctionnels où la radiothérapie métabolique par iode 131 joue un rôle principal. Depuis quelques années, il existe une expérience croissante dans la thermoablation des nodules thyroïdiens par radiofréquence, avec des résultats très encourageants. Cet article a pour but de discuter la place de la thermoablation par radiofréquence dans la prise en charge des nodules thyroïdiens bénins en passant en revue les indications, les effets indésirables et les limitations de cette méthode.

RESUMO

In patients with diabetes, pregnancy is associated with high maternal and fetal risks, especially in unplanned pregnancies. Current evidence confirms that timely family planning and interdisciplinary care and management starting at the preconceptional period can optimize metabolic control and significantly reduce these risks. The purpose of this article is to summarize the different aspects to consider as well as provide tools to use when preparing patients with diabetes for a pregnancy.


Chez les patientes diabétiques, la grossesse est associée à des hauts risques materno-fœtaux, notamment lorsqu'elle n'est pas planifiée. L'évidence actuelle confirme que la planification familiale opportune ainsi qu'une prise en charge interdisciplinaire depuis la période préconceptionnelle permettent d'optimiser le contrôle métabolique et de diminuer ces risques de façon significative. Le but de cet article est de résumer les différents aspects à considérer ainsi que de fournir des outils à utiliser lors de la préparation des patientes avec un diabète à une grossesse.
