Overall, both scanning conditions produced good levels of test-retest reliability. While the pure resting-state condition showed higher test-retest reliability for 18 of the 28 analysed networks, the low cognitive demand paradigm produced higher test-retest reliability for 8 of the 28 brain networks (i.e. visual, sensorimotor and frontal areas); in 2 of the 28 brain networks no significant changes could be detected. These results are relevant to planning of longitudinal studies, as higher test-retest reliability generally increases statistical power. This work also makes an important contribution to neuroimaging where optimising fcMRI experimental scanning conditions, and hence data visualisation of brain function, remains an on-going topic of interest. In this chapter, we provide a full methodological explanation of the two paradigms and our analysis so that readers can apply them to their own scanning protocols.Regional anaesthesia involves targeting specific peripheral nerves with local anaesthetic. It facilitates the delivery of anaesthesia and analgesia to an increasingly complex, elderly and co-morbid patient population. Regional anaesthesia practice has been transformed by the use of ultrasound, which confers advantages such as accuracy of needle placement, visualisation of local anaesthetic spread, avoidance of intraneural injection and the ability to accommodate for anatomical variation.An US beam is generated by the application of electrical current to an array of piezoelectric crystals, causing vibration and consequential production of high-frequency sound waves. The sound energy is reflected at tissue interfaces, detected by the piezoelectric crystals in the ultrasound probe, and most frequently displayed as a 2D image.Optimising image acquisition involves selection of the appropriate US frequency this represents a trade-off between image resolution (better with high frequency) and tissue penetration/beam oped that continuing advances in nerve and needle visualisation, as described in this chapter, will expedite that process.In this chapter we present an overview of web-based frameworks for visualisation of medical and biological data, with emphasis on visualisation of volumetric data such as radiological data (e.g. magnetic resonance imaging, computed tomography or positron emission tomography) and microscopy data (e.g. focused ion beam scanning electron microscopy). We compare web-based frameworks with state-of-the-art standalone visualisation tools and point out the advantages and disadvantages of both. We also present our open-source web-based visualisation environment Med3D.Background Dosimetry after peptide receptor radionuclide therapy (PRRT) is increasing; however, comparing or pooling of dosimetric results can be challenging since different approaches are used. The aim of this study was to perform a head-to-head comparison of post-PRRT curve fitting and dosimetry obtained from two commercial software Hybrid Viewer Dosimetry and PLANET Dose. Methods Post-therapy imaging included planar scintigraphy at 0.5, 4, 24 and 72 h post-injection of [177Lu]Lu-DOTA-TATE for kinetics and SPECT/CT at 24 h for quantification. On planar imaging, 2 cm regions-of-interest were positioned within the inferior pole of the kidneys and kidney cortex was segmented on low-dose CT. On both planar and SPECT/CT, 2 cm spheres were positioned in the proximal humerus (red marrow equivalent) and in the region with the highest uptake in tumour lesions. TACs were estimated with mono- and bi-exponential fits in both software systems, after which tissue absorbed (kidney, red marrow, tumour) and biological effecquisition protocol, timing and lesions definition.Purpose Sexual health is an important quality-of-life concern for cancer patients and survivors, but a difficult discussion topic for patients and healthcare professionals. The most important barriers causing healthcare professionals to avoid the topic are lack of education and lack of knowledge. How effective education about sexual health is for oncology healthcare professionals is not clear. The aim of this review is to examine the effectiveness of interventions in improving the provision of sexual healthcare for cancer patients. Methods A systematic literature review was conducted according to PRISMA guidelines using the following data sources PubMed, PsychInfo, Embase and Emcare. Quantitative research was included which contained pre-intervention and post-intervention outcomes. The assessment of the studies was conducted independently by two reviewers. A third reviewer was involved if there was no consensus. Results Seven studies were included. In total, 572 oncology healthcare professionals participated, including physicians, nurses and allied healthcare professionals. Interventions consisted of 6 face-to-face sessions and one online program. Primary objectives of the studies were the assessment of improvement in knowledge about sexual health, improvement of practice, frequency of discussing sexual health and comfort level and the decline of perceived barriers to discussing sexual health. Studies showed that interventions resulted in improved realization of the objectives. Conclusions Although improvement in the knowledge of healthcare professionals was achieved, it was not possible to give an overall recommendation for the development of interventions due to the limited number of studies and heterogeneity of the data. Implications for cancer survivors Sexual health is an important area of survivorship that is often neglected. Many oncology healthcare professionals lack training and knowledge to provide such care. More evidence-based practices are needed to improve sexual healthcare for cancer survivors.The aim of present research work was to design, fabricate, optimize, and evaluate allopurinol (ALLO)-loaded bovine serum albumin nanoparticles (ABNPs) for kidney targeting of the drug and exploring the potential of fabricated ABNPs for management of hyperuricemia-related nephrolithiasis. see more ABNP formulation was prepared by employing desolvation technique, and its optimization was conducted by 2-factor-3-level central composite design (CCD) in order to achieve minimum particle size (PSA) and polydispersity index (PDI), maximum entrapment efficiency (EE), and zeta potential (ZP). Further, the optimized formulation (ABNPsopt) was also assessed for in vitro drug release study, TEM, DSC, XRD analysis, FTIR spectroscopy, and in vivo animal study. The in vivo study revealed that after 2 h of ABNPsopt administration, a significant concentration of ALLO was present in kidney (21.26-fold) as compared with serum while in case of standard pure drug group; no drug was seen in mice kidney and serum post 2 h administration, which indicates successful targeting of ALLO by formulating its albumin nanoparticles.
