Controlling the stability of monodisperse phospholipid-coated microbubbles by tuning their buckling pressure.

Hypothesis: Monodisperse phospholipid-coated microbubbles, with a size and resonance frequency tuned to the ultrasound driving frequency, have strong potential to enhance sensitivity, efficiency, and control in emerging diagnostic and therapeutic applications involving bubbles and ultrasound. A key requirement is that they retain their gas volume and shell material during physiologic pressure changes and withstand the overpressure during intravenous injection. The shell typically comprises a mixture of a phospholipid (e.

[ORL : what's new in 2024].

This article highlights recent advancements in otorhinolaryngology. It reviews innovations in managing sudden sensory-neural hearing loss through low-dose glucocorticoid treatments and explores pediatric audiology breakthroughs, particularly gene therapy for DFNB9 deafness. In speech pathology and oncology, a new minimally invasive robotic surgical approach enhances organ preservation for head and neck cancers.

[Oncology. Antibody-drug conjugates : a challenging innovation].

New therapeutic agents in oncology are emerging rapidly, both in terms of the number of approved drugs and the technological and biological innovation of new treatments. Antibody-drug conjugates (ADC) offer a promising cancer therapy by specifically targeting tumor cells. ADC are composed of a monoclonal antibody recognizing the tumor cell via specific antigens, coupled with a potent cytotoxic agent that resembles classical chemotherapy.

[Nephrology : what's new in 2024 (II)].

Certain molecules, such as GLP-1 agonists and endothelin antagonists, possess nephroprotective properties. When treating IgA nephropathy, endothelin antagonists and sibeprenlimab have shown effectiveness in slowing the progression of chronic kidney isease. Additionally, the infusion of amino acids can reduce the incidence of mild acute kidney injury following cardiac surgery.

[Gastroenterology and hepatology : what's new in 2024].

The year 2024 was rich in developments in the field of hepatology, gastroenterology, and interventional endoscopy. New molecules have been developed for the treatment of metabolic steatohepatitis, primary biliary cirrhosis, and inflammatory bowel diseases. Technological progress now makes it possible to perform screening measurements for portal hypertension directly under echo-endoscopic guidance and to extend the use of intraluminal stents to surgically modified anatomies.

[Endocrinology : what's new in 2024].

In this article, we look at a selection of recent developments in various areas of endocrinology. We focus on advances in endocrine pharmacotherapy and endocrine surgery, addressing several areas: a) the thyroid safety of Glucagon-Like Peptide-1 (GLP1) analogues; b) the efficacy of adrenal surgery for mild autonomous cortisol secretion; c) crinecerfont in the management of congenital adrenal hyperplasia in adults and children; d) paltusotin as a novel oral therapy for acromegaly and e) TransCon PTH (palopegteriparatide) as a novel therapy for chronic hypoparathyroidism.

[Cardiology. Rhythmology, hypertension, dyslipidemia and aortic diseases].

Atrial fibrillation (AF) is common and its treatment is complex. The new European guidelines emphasize a patient-centered approach, considering the risk factors that contribute to AF and their management in primary and secondary prevention. Recent advances in electrophysiology include the development of new ablation techniques and the implantation of a leadless bicameral pacemaker.

[Palliative care : not wait for the end of life].

Patients with serious illnesses wish to maintain their autonomy and decide the course of their end of life. The role of healthcare professionals is to assess the patient's understanding of their illness, help them become aware of the progression of their condition, and adapt these conversations according to the patient's emotional state, while providing regular spaces for discussion. Some patients continue to have expectations that may seem unrealistic despite a limited prognosis.

[Neurorehabilitation in Parkinson's disease : focus on physical therapy].

Parkinson's disease affects around 6 million people worldwide. It causes both motor and non-motor symptoms. Since there is no cure, medical treatment aims to improve patients' quality of life.

[Trust during medical consultations with trans* people].

Trust is a particularly important element in a healthcare relationship, but it is often misunderstood. In this article, we explore the trust relationship between patients and healthcare professionals and the expectations underpinning it. We then look at some of the expectations of trans* people in the context of medical consultations that are not related to medical transition.

[Gender and substance use : men exposed, women vulnerable].

The use of psychoactive substances affects more men than women, with a prevalence that is 1.3 to 2 times higher, except for the use of sedatives. Men are also more affected by accidents, injuries, and acts of violence.

Effect of repeated sprint training in hypoxia on acute and chronic redox balance modulation.

Little is known regarding the effects high-intensity training performed in hypoxia on the oxidative stress and antioxidant systems. The aim of this study was to assess the potential effect of 4 weeks of repeated sprint training in hypoxia (RSH) on the redox balance. Forty male well-trained cyclists were matched into two different interventions (RSH,  = 20) or in normoxia, RSN,  = 20) and tested twice (before (Pre-) and after (Post-) a 4-week of training) for performance (repeated sprint ability (RSA) test), oxidative stress, and antioxidant status.

[The iatrogenic risk of institutional care in the management of patients with anorexia nervosa].

This article explores the potential iatrogenic impact of institutional care on patients suffering from anorexia nervosa, based on a perspective drawn from the human and social sciences. In particular, it highlights the social mechanisms - such as the collision of intentions, pathological emulation, stigmatization and identity dedifferentiation - that can aggravate pathology in the hospital setting. Four recommendations are put forward for rethinking care, favoring a more holistic and less iatrogenic approach.

Changes in sensor recorded activity patterns and neuropsychiatric symptoms after deep brain stimulation for Parkinson's disease: 5 case reports.

Background: Effects of subthalamic nucleus deep brain stimulation (STN-DBS) on neuropsychiatric symptoms of Parkinson's disease (PD) remain debated. Sensor technology might help to objectively assess behavioural changes after STN-DBS.

Case Presentation: 5 PD patients were assessed 1 before and 5 months after STN-DBS with the Movement Disorders Society Unified Parkinson's Disease Rating Scale part III in the medication ON (plus postoperatively stimulation ON) condition, the Montreal Cognitive Assessment, the Questionnaire for Impulsive-Compulsive Behaviors in Parkinson's Disease Rating Scale present version, the Hospital Anxiety and Depression Scale and the Starkstein Apathy Scale.

Hemodynamic Valve Deterioration After Transcatheter Aortic Valve Replacement: Incidence, Predictors, and Clinical Outcomes.

Background: Reports on the durability of transcatheter aortic valve replacement (TAVR) prostheses are scarce and confounded by varying definitions and competing risks of death.

Objectives: The authors sought to determine the incidence, predictors, and clinical outcomes of hemodynamic valve deterioration (HVD) according to the Valve Academic Research Consortium 3 definition after TAVR.

Methods: We analyzed consecutive patients undergoing TAVR in the prospective Bern TAVI (Transcatheter Aortic Valve Implantation) registry between August 2007 and June 2022 for the incidence and predictors of HVD and performed case control-matching to compare outcomes according to HVD.
