Analytical solution of a microrobot-blood vessel interaction model.

This study develops a dynamics model of a microrobot vibrating in a blood vessel aiming to detect potential cancer metastasis. We derive an analytical solution for microrobot's motion, considering interactions with the vessel walls modelled by a linear spring-dashpot and a constant damping value for blood viscosity. The model facilitates instantaneous state transitions of the microrobot, such as contact with the vessel wall and free motion within the fluid.

Previous research has examined ChatGPT's capabilities across various medical specialties and exams, with mixed results, especially in the interpretation of complex radiological images.

Hypothesis: ChatGPT version 4o was capable of achieving a score equal to or higher (not lower) than that of residents for the DES exam.

The enhanced national pharmacovigilance system implemented for COVID-19 vaccines in France: A 2-year experience report.

In March 2020, World Health Organization recognized severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emergence as a public health emergency of international concern. One of the major preventative measures developed against coronavirus disease 2019 (COVID-19) was vaccines. To monitor their use and safety of vaccines from the first utilization in humans during clinical development phases to implementation for the general population, an enhanced national pharmacovigilance system was enabled by the French National Agency for Medicines and Health Products Safety in collaboration with the 30 Regional Pharmacovigilance Centres.

Six-month outcomes after a GP phone call during the first French COVID-19 lockdown (COVIQuest): a cluster randomised trial using medico-administrative databases.

Objectives: The first COVID-19 lockdown raised concerns about reduced access to primary care, especially for people with chronic diseases particularly at risk in the absence of follow-up. However, the COVIQuest trial, evaluating the impact of a general practitioner (GP) phone call (intervention) to chronic patients with cardiovascular disease (CVD) or mental health disorder (MHD) concluded that the intervention had no effect at 1 month on the rate of self-reported hospitalisations in the CVD subtrial, whereas the intervention group in MHD subtrial might have a higher rate. This second part of the study aimed to describe the 6 month hospitalisation and specialised consultation rates, using the French health data system ().

Multiparameter growth-performance monitoring of Holstein dairy heifers fed on moderate- or high-energy feeding plans from birth to puberty.

Today, dairy cattle farmers are seeking to optimize expenditure and productivity throughout the lives of their animals by focusing on efficiency at all levels. One strategy for bringing forward the start of a dairy cow's profitability phase is to advance the onset of puberty and reduce the animal's age at their first calving. Thus, one objective of this study was to feed two groups of Holstein dairy heifers the same diet but in different quantities, with the aim of generating a growth differential of at least 200 g/day between the two groups.
