Background: Meropenem-vaborbactam (MEM-VAB) is a novel carbapenem-beta-lactamase-inhibitor combination that demonstrates activity against carbapenem-resistant (CR) Gram-negative bacteria, and more specifically KPC-producers, since vaborbactam is an effective inhibitor of KPC enzymes in vitro. This study aimed to describe the initial uses and efficacy of MEM-VAB for compassionate treatment during the first 21 months following its early access in France.
Method: A national multicenter retrospective study was conducted, including all patients who received at least one dose of MEM-VAB between 20 July 2020, and 5 April 2022.
Background: Angioedema (AE) due to acquired C1-inhibitor deficiency (AAE-C1-INH) is a rare disease associating recurrent edema of mucosa and skin. Several underlying diseases have been reported, mainly lymphoproliferative diseases and monoclonal gammopathy. However, 15 to 20% of patients never exhibit such a hematological condition.

Article Synopsis
- Aging leads to functional decline and cognitive impairment, but caloric restriction (CR) can help delay these effects and improve cognitive function in older adults.
- There is a connection between memory, learning, and the circadian clock, which indicates that timing and regulation are essential for cognitive processes.
- Research showed that late-onset CR restored circadian rhythms and improved cognitive abilities in aging rats, suggesting that lifestyle changes like CR could preserve brain health as we age.
Angioedema due to Acquired C1-Inhibitor Deficiency Associated With Monoclonal Gammopathies of Undetermined Significance Characteristics of a French National Cohort.
J Allergy Clin Immunol Pract
December 2024
Article Synopsis
- MGUS-associated angioedema due to acquired C1 inhibitor deficiency (AAE-C1-INH) hasn't been specifically characterized before, prompting this study to explore its biological and clinical features over 30 years in France.
- In a study of 41 patients, most had anti-C1INH antibodies, and treatments included acute management and long-term prophylaxis, with a significant number developing malignant blood disorders like lymphoma or myeloma.
- The study found a link between the remission of angioedema and the underlying hematological malignancy, emphasizing the need for regular hematological evaluations in patients with MGUS-AE-C1-INH.
Aging abolishes circadian rhythms and disrupts temporal organization of antioxidant-prooxidant status, endogenous clock activity and neurotrophin gene expression in the rat temporal cortex.
Neuroscience
November 2024
Disruption of circadian rhythms contributes to deficits in cognitive functions during aging. Up to date, the biochemical, molecular and chronobiological bases of such deterioration have not been completely elucidated. Here, we aim: 1) to investigate the endogenous nature of 24 h-rhythms of antioxidant defenses, oxidative stress, clocḱ's, and neurotrophic factors expression, in the rat temporal cortex (TC), and 2) to study the consequences of aging on the circadian organization of those factors.
