Screening for vulnerability in older cancer patients: the ONCODAGE Prospective Multicenter Cohort Study.

Background: Geriatric Assessment is an appropriate method for identifying older cancer patients at risk of life-threatening events during therapy. Yet, it is underused in practice, mainly because it is time- and resource-consuming. This study aims to identify the best screening tool to identify older cancer patients requiring geriatric assessment by comparing the performance of two short assessment tools the G8 and the Vulnerable Elders Survey (VES-13).

Screening tools for frailty in primary health care: a systematic review.

Frailty is the loss of resources in several domains leading to the inability to respond to physical or psychological stress. The evaluation of frailty is generally carried out using the Comprehensive Geriatric Assessment. For this evolving and potentially reversible syndrome, screening and early intervention are a priority in primary health care, and general practitioners require a simple screening tool.

Synthesis and angiotensin II receptor antagonist activity of C-linked pyrazole derivatives.

The synthesis and pharmacological activity of new nonpeptide angiotensin II (AII) receptor antagonists are presented. These 5-O-substituted and 5-C-substituted 3-alkylpyrazole derivatives represent a new series of antagonists and have led to the discovery of compounds with potent oral antihypertensive activity in a renal artery-ligated rat model. In vitro, they displayed a high affinity for rat adrenal AII receptors.

Synthesis and SAR studies of novel triazolopyrimidine derivatives as potent, orally active angiotensin II receptor antagonists.

The synthesis and pharmacological activity of new nonpeptide angiotensin II (AII) receptor antagonists are presented. These [1,2,4]-triazolo[1,5-c]pyrimidine and 1,2,4-triazolo[4,3-c]pyrimidine derivatives represent a new class of bicyclic antagonists that produced a potent, oral antihypertensive activity in the renal artery-ligated rat model. In vitro, they displayed a high affinity for rat adrenal AII receptors and were found to be specific for the AT1 receptor subtype.

Synthesis and structure-activity relationships of novel benzimidazole and imidazo[4,5-b]pyridine acid derivatives as thromboxane A2 receptor antagonists.

A series of 1-benzylbenzimidazole and 3-benzylimidazo[4,5-b]pyridine substituted in the 2-position by an alkanoic or mercaptoalkanoic acid chain was synthesized for evaluation as potential thromboxane A2/prostaglandin H2 (TXA2/PGH2) receptor antagonists. The affinity of each compound for washed human platelet TXA2/PGH2 receptors was determined by radioligand binding studies using [125I]PTA-OH. Structure-activity relationships led to the conclusions that 2-alkanoic acid derivatives were slightly more potent than 2-mercaptoalkanoic acids and that compounds possessing a 3,3-dimethylbutanoic acid in the 2-position were definitely the most potent with Ki values of 4-39 nM (11a, 11g-x, 37a, 37f-o, 23a-c).
