Comparisons between regulatory authorities of similar size and regulatory characteristics facilitate value-added benchmarking and provide insight into regulatory performance. Such comparisons highlight areas for improvement as authorities move toward achieving their regulatory goals and stakeholders' demands. The aims of this study were to compare the registration process and the regulatory review model of the South African Medicines Control Council (MCC) to that of four other similar-sized regulatory authorities and to identify areas for improvement that may inform recommendations to the South African Health Products Regulatory Authority (SAHPRA) as it looks to re-engineer and enhance the registration process in South Africa. A questionnaire describing the organisational structure, the registration process, good review and decision-making practices of the MCC was completed by the author (AK) for the purpose of this study and validated by the Registrar of the MCC. Similar questionnaires were also completed and validated by Australia's Therapeutic Goods Administration (TGA), Canada's Health Canada, Singapore's Health Science Authority (HSA) and Switzerland's Swissmedic. A comparison of the MCC regulatory process with the four comparative agencies indicated that they all have similar requirements and employ a full-review model although the timelines for the MCC were considerably longer. However, similar quality measures were implemented by all authorities as part of their good review practices (GRevP) including prioritising transparency, communication, continuous improvement initiatives and training. Comparisons made through this study provided insight into the areas of the MCC registration process that may be improved and have informed recommendations to SAHPRA including the implementation of facilitated regulatory pathways, definition of targets for key milestones in regulatory review and formal implementation and monitoring of GRevP. In order to build quality into the review process the application of a standardised template for the clinical assessment of medicines such as the Universal Methodology for Benefit-Risk Assessment (UMBRA) could be considered as well as enhancing transparency and communication through the application of an electronic management system and the development of publicly available summaries for the basis of approval.

Background: Employing a custom 60-channel single-transmit/32-channel receive Tic-Tac-Toe (TTT) coil in 7T MRI imaging has enhanced the resolution and contrast for identifying White Matter Hyperintensities (WMHs), which are critical markers in Alzheimer's disease and related dementias (AD/ADRD).
Method: The method involves resecting the left hemisphere of the brain, excluding the cerebellum, followed by embalming in 10% formalin. 1.
Alzheimers Dement
December 2024
University of Washington, Seattle, WA, USA.
Background: The structural, cellular, and biomolecular research necessary for a mechanistic understanding of Alzheimer's Disease (AD) relies on brain tissue collected according to a brain sampling protocol (BSP) and preserved in biorepositories. Such research involves discipline-specific terminology such as cytoarchitectonic domains, brain network nodes, etc. This specificity can result in iterative, time-consuming, and error-prone request processes.

Aims: Caution around the COVID-19 pandemic resulted in visitation restrictions to prevent the spread of the virus among vulnerable older persons living in long-term care (LTC), which posed a threat to individual well-being and family togetherness across the globe. The purpose of this study was to explore family caregiver's experience of having a person who is living with dementia residing in a long-term care facility during the COVID-19 pandemic.
Design: Qualitative descriptive study using constructivist grounded theory (GT) methodology.

This paper describes the integration of environmental physiotherapy education into the physiotherapy curriculum in a New Zealand university in response to the environmental physiotherapy agenda and the University of Otago Sustainability Framework. We describe and discuss three learning activities, the associated challenges and lessons learnt, and the current position. Given the encompassing nature of environmental and health interactions, we aimed for multilayer immersive experiences using a range of pedagogical approaches.

This paper introduces a novel unsupervised inverse-consistent diffeomorphic registration network termed IConDiffNet, which incorporates an energy constraint that minimizes the total energy expended during the deformation process. The IConDiffNet architecture consists of two symmetric paths, each employing multiple recursive cascaded updating blocks (neural networks) to handle different virtual time steps parameterizing the path from the initial undeformed image to the final deformation. These blocks estimate velocities corresponding to specific time steps, generating a series of smooth time-dependent velocity vector fields.
