A review of the analytical techniques for the detection of anabolic–androgenic steroids within biological matrices

Anabolic–androgenic steroids (AASs) and other image and performance enhancing drugs (IPEDs) are controlled by governments and sport institutions such as the World Anti-doping Agency (WADA). Although elite athletes and professional bodybuilders are the most visible AAS abusers, the introduction of the internet has increased the accessibility of AASs, with use being observed among recreational gym goers at increasing prevalence. Despite reported increase in use, routine analysis for these substances is uncommon, with many forensic laboratories opting to outsource AAS analysis. This review collates information regarding the extraction and analysis of AASs from various biological matrices with the considered purpose of providing a reference for the development of AAS methods to allow for routine detection by forensic laboratories

Modelling systematic anatomical uncertainties of head and neck cancer patients during fractionated radiotherapy treatment

Head and neck cancer patients experience systematic anatomical changes as well as random day to day anatomical changes during fractionated radiotherapy treatment. Modelling the expected systematic anatomical changes could aid in creating treatment plans which are more robust against such changes. A patient specific (SM) and population average (AM) model are presented which are able to capture the systematic anatomical changes of some head and neck cancer patients over the course of radiotherapy treatment. 
Inter- patient correspondence aligned all patients to a model space. Intra- patient correspondence between each planning CT scan and on treatment cone beam CT scans was obtained using diffeomorphic deformable image registration. The stationary velocity fields were then used to develop B-Spline based SMs and AMs. The models were evaluated geometrically and dosimetrically. A leave-one-out method was used to compare the training and testing accuracy of the models. 
Both SMs and AMs were able to capture systematic changes. The average surface distance between the registration propagated contours and the contours generated by the SM was less than 2mm, showing that the SM are able to capture the anatomical changes which a patient experiences during the course of radiotherapy. The testing accuracy was lower than the training accuracy of the SM, suggesting that the model overfits to the limited data available and therefore also captures some of the random day to day changes. For most patients the AMs were a better estimate of the anatomical changes than assuming there were no changes, but the AMs could not capture the variability in the anatomical changes seen in all patients. No difference was seen in the training and testing accuracy of the AMs. These observations were highlighted in both the geometric and dosimetric evaluations and comparisons. The large patient variability highlights the need for more complex, capable population models

Hybrid self‐assembling peptide/gelatin methacrylate (gelma) bioink blend for improved bioprintability and primary myoblast response

Organ fabrication as the solution to renewable donor demands requires the ability to spatially deposit viable cells into biologically relevant constructs necessitating reliable and effective cell deposition through bioprinting and the subsequent ability to mature. However, effective bioink development demands advances in both printability and control of cellular response. Effective bioinks are designed to retain shape fidelity, influence cellular behavior, having bioactive morphologies stiffness and highly hydrated environment. Hybrid hydrogels are promising candidates as they reduce the need to re‐engineer materials for tissue‐specific properties, with each component offering beneficial properties. Herein, a multicomponent bioink is developed whereby gelatin methacrylate (GelMA) and fluorenylmethoxycarbonyprotected self‐assembling peptides (Fmoc‐SAPs) undergo coassembly to yield a tuneable bioink. This study shows that the reported fibronectin‐inspired fmoc‐SAPs present cell attachment epitopes RGD and PHSRN in the form of bioactive nanofibers and that the GelMA enables superior printability, stability in media, and controlled mechanical properties. Importantly, when in the hybrid format, no disruption to either the methacrylate crosslinking of GelMA, or self‐assembled peptide fibril formation is observed. Finally, studies with primary myoblasts show over 98% viability at 72 h and differentiation into fused myotubes at one and two weeks demonstrate the utility of the material as a functional bioink for muscle engineering. In this work, muscle tissue is 3D‐bioprinted with a novel bioink formulation. The bioink presents fibrous bioactive properties of the body's native scaffold, while also improving biofabrication outcomes. Self‐assembling peptides are combined with GelMA creating a hybrid bioink. This work sets the stage for future hybrid bioinks for muscle biofabrication

Qualitative insights into the feelings, knowledge, and impact of SUDEP: A narrative synthesis

People with epilepsy (PWE) have a two- to threefold increased chance of premature death due to the condition. Interested in exploring the first-person perspective on this topic, we conducted a narrative synthesis to present the qualitative insight of PWE, their family, friends, and healthcare providers (HCPs) in relation to epilepsy-related death. A comprehensive electronic search of all peer-reviewed qualitative studies was conducted through databases using relevant keywords and Medical Subject Headings (MeSH) terms. Handsearching and exploration of pertinent gray literature was conducted thereafter. After a comprehensive literature search, the decisions of inclusion of literature were discussed and confirmed between the two authors. A total of 20 peer-reviewed papers were included. Within this, 17 were qualitative or mixed methods studies, and three were gray literature and guidelines/recommendations in discussing sudden unexpected death in epilepsy (SUDEP) with PWE and their families. The resultant main categories were the following: a) understanding of SUDEP and b) discussion of SUDEP. Findings show that there is an overall lack of understanding of unexpected epilepsy-related death for PWE and their relations. The literature focused on the education of PWE and their family in relation to SUDEP, and therefore, there is a lack of discussion on the general topic of epilepsy-related death. Findings show the conflicting perceptions, feelings, and thought processes that occur in learning about and deciding to discuss SUDEP as a HCP, PWE, or family/friend of a PWE. The literature suggests that it would be appropriate and necessary to discuss the topic of SUDEP with patients and their family members upon diagnosis

Extent, causes, and consequences of small RNA expression variation in human adipose tissue.

Small RNAs are functional molecules that modulate mRNA transcripts and have been implicated in the aetiology of several common diseases. However, little is known about the extent of their variability within the human population. Here, we characterise the extent, causes, and effects of naturally occurring variation in expression and sequence of small RNAs from adipose tissue in relation to genotype, gene expression, and metabolic traits in the MuTHER reference cohort. We profiled the expression of 15 to 30 base pair RNA molecules in subcutaneous adipose tissue from 131 individuals using high-throughput sequencing, and quantified levels of 591 microRNAs and small nucleolar RNAs. We identified three genetic variants and three RNA editing events. Highly expressed small RNAs are more conserved within mammals than average, as are those with highly variable expression. We identified 14 genetic loci significantly associated with nearby small RNA expression levels, seven of which also regulate an mRNA transcript level in the same region. In addition, these loci are enriched for variants significant in genome-wide association studies for body mass index. Contrary to expectation, we found no evidence for negative correlation between expression level of a microRNA and its target mRNAs. Trunk fat mass, body mass index, and fasting insulin were associated with more than twenty small RNA expression levels each, while fasting glucose had no significant associations. This study highlights the similar genetic complexity and shared genetic control of small RNA and mRNA transcripts, and gives a quantitative picture of small RNA expression variation in the human population
