Why recommended visit intervals should be extracted when conducting longitudinal analyses using electronic health record data: examining visit mechanism and sensitivity to assessment not at random [PDF]
arXivElectronic health records (EHRs) provide an efficient approach to generating rich longitudinal datasets. However, since patients visit as needed, the assessment times are typically irregular and may be related to the patient's health. Failing to account for this informative assessment process could result in biased estimates of the disease course.

Enhancing Medical Image Segmentation: Optimizing Cross-Entropy Weights and Post-Processing with Autoencoders [PDF]
arXiv, 2023 The task of medical image segmentation presents unique challenges, necessitating both localized and holistic semantic understanding to accurately delineate areas of interest, such as critical tissues or aberrant features. This complexity is heightened in medical image segmentation due to the high degree of inter-class similarities, intra-class ...

A Data-Efficient Deep Learning Framework for Segmentation and Classification of Histopathology Images [PDF]
arXiv, 2022 The current study of cell architecture of inflammation in histopathology images commonly performed for diagnosis and research purposes excludes a lot of information available on the biopsy slide. In autoimmune diseases, major outstanding research questions remain regarding which cell types participate in inflammation at the tissue level, and how they ...

Bias in mixed models when analysing longitudinal data subject to irregular observation: when should we worry about it and how can recommended visit intervals help in specifying joint models when needed? [PDF]
arXivIn longitudinal studies using routinely collected data, such as electronic health records (EHRs), patients tend to have more measurements when they are unwell; this informative observation pattern may lead to bias. While semi-parametric approaches to modelling longitudinal data subject to irregular observation are known to be sensitive to ...

Case Report of Dermatomyositis With Features of the Wong Variant Developing Post-Trastuzumab Therapy for Breast Cancer. [PDF]
Australas J DermatolABSTRACT Drug‐induced dermatomyositis can be challenging to distinguish from paraneoplastic dermatomyositis. Rarely, antibodies directed against human epidermal growth factor receptor 2 (HER‐2), such as trastuzumab, may trigger dermatomyositis, and immune checkpoint inhibitors may incite the Wong variant of dermatomyositis, characterised by clinical ...
