Aortic stenosis remains one of the most frequent valvulopathy worldwide, burdened with great mortality and morbidity, and for which there is not yet an effective preventive approach, although the pathophysiological mechanisms involved in its development are better understood nowadays. Its cure, however, has been revolutionized in the last decade by the advent of transcatheter aortic valve implantation, or TAVI (also named transcatheter aortic valve replacement or TAVR). ⋯ In this review, we describe the pathophysiological mechanisms leading to severe aortic stenosis and the main ongoing randomized controlled trials targeting them. We describe the indication for surgical or percutaneous aortic valve replacement and the main complications following the procedure.

With aging worldwide population and the high incidence of cancer in the population of people over 75 years old, there is a need for oncologists and geriatricians to strengthen their collaboration to improve elderly patients care. Complexity of cancer and aging issues must be considered simultaneously to establish a personalized care plan. Thus, the G8 is a screening tool that allows to identify patients who should benefit from a geriatric assessment, which is a key step in the management process. ⋯ The presence of malnutrition and functional impairment leading to dependence on basic activities of daily living had a significant impact on this change in therapeutic choice. Survival is not only impacted by malnutrition and functional impairment but also by the presence of severe comorbidities and thymic and neurocognitive impairment. The patient's choice must remain at the center of the elaboration of the care plan with the oncologists and geriatricians in order to propose the most appropriate treatment for his or her situation.

Fish odor syndrome (FOS) is a rare metabolic disorder that manifests as "rotten fish" body odor and is caused by the excretion of trimethylamine (TMA) in body fluids. This disease can have a negative impact on the social life of affected patients. ⋯ Fish odor syndrome is a rare and unrecognized disease that can affect the quality of life of affected persons. Following laboratory diagnosis, treatment is often effective.

Nitrous oxide (N2O) is used since the eighteenth century as an anesthetic and analgesic but also for recreational use. If the labelled uses of N2O and their modalities are nowadays perfectly framed, the misuse of N2O takes very alarming proportions among teenagers and young adults. This misuse is the cause of acute (hypoxia, barotrauma, burns, neuropsychiatric disorders) and chronic complications if repeated (myeloneuropathy, anemia, thrombosis, inhalant use disorder). ⋯ The management of chronic complications is based on vitamin B12 supplementation. The best biomarker of chronic N2O exposure is the elevation of the plasmatic level of methylmalonic acid. In all cases of recreational misuses, addiction treatment is necessary to prevent complications or their worsening by providing information in order to stop consumption.

Hepatitis B virus is a small enveloped RNA virus, which replicates independently but requires the hepatitis B virus (HBV) to provide the envelope proteins necessary for the assembly of its own viral particles. Approximately 5% of chronic hepatitis B virus carriers are infected with HDV. HBV vaccination remains the best preventive treatment for HDV. ⋯ The historical treatment was based on PEG-IFN with many side effects. A new treatment has been approved, Bulevirtide (Hepcludex®) an HDV/HBV entry inhibitor, for any patient with chronic hepatitis Delta infection (CHD) with active replication (except in decompensated cirrhosis), at a dose of 2mg/day by subcutaneous injection. The exact duration on-treatment is unknown, thus treatment should be continued if clinical benefit is observed.
