Residues of antibiotics (ABs) in the aquatic environment and in food of animal origin represent a major concern, as prolonged exposure to ABs is a serious health hazard, related to both the side effects of prolonged use and the risk of developing bacterial resistance to various ABs. Given the low levels of the AB residues in complex matrices, the development of sensitive analytical methods represents a major challenge. This is certainly true for the aminoglycoside ABs (AGs) which lack a chromophore and show poor chromatographic properties in reversed-phase liquid chromatography. This paper reviews the current state of the art in the determination of AGs. Attention is paid to extraction, sample clean-up, chromatographic separation, and detection of AGs in both environmental and food samples and in plasma and serum. A general workflow for the analysis of AGs is presented which takes into account the matrix and required level of information.

Background: Over the years, the processing of research proposals for ethical approvals have been done manually through a review of hard copies. Longer turn-around-time, increased financial costs to researchers and cumbersome submission processes are few of the challenges inherent to paper-based review of research proposals. This has necessitated the shift to electronic management of research proposals, Research Ethics Information Management Systems (REIMS).

Background: Stigma significantly impacts individuals with Parkinson's disease (PD) and their caregivers, exacerbating social isolation, psychological distress, and reducing quality of life (QoL). Although considerable research has been conducted on PD's clinical aspects, the social and emotional challenges, like stigma, remain underexplored. Addressing stigma is crucial for enhancing well-being, fostering inclusivity and improving access to care and support.

This study presents an advanced methodology for 3D heart reconstruction using a combination of deep learning models and computational techniques, addressing critical challenges in cardiac modeling and segmentation. A multi-dataset approach was employed, including data from the UK Biobank, MICCAI Multi-Modality Whole Heart Segmentation (MM-WHS) challenge, and clinical datasets of congenital heart disease. Preprocessing steps involved segmentation, intensity normalization, and mesh generation, while the reconstruction was performed using a blend of statistical shape modeling (SSM), graph convolutional networks (GCNs), and progressive GANs.

The clinical management of people with multidrug-resistant (MDR) human immunodeficiency virus (HIV) remains challenging despite continued development of antiretroviral agents. A 58-year-old male individual with MDR HIV and Kaposi sarcoma (KS) was treated with a new antiretroviral regimen consisting of anti-CD4 domain 1 antibody UB-421 and capsid inhibitor lenacapavir. The individual experienced delayed but sustained suppression of plasma viremia and a substantial increase in the CD4 T cell count.
