Epitopes, in the context of T cell recognition, are short peptides typically derived by antigen processing, and presented on the cell surface bound to MHC molecules (HLA molecules in humans) for TCR scrutiny. The identification of epitopes is a context-dependent process, with consideration given to, for example, the source pathogen and protein, the host organism, and state of the immune reaction (e.g., following natural infection, vaccination, etc.). In the following review, we consider the various approaches used to define T cell epitopes, including both bioinformatic and experimental approaches, and discuss the concepts of immunodominance and immunoprevalence. We also discuss HLA polymorphism and epitope restriction, and the resulting impact on the identification of, and potential population coverage afforded by, epitopes or epitope-based vaccines. Finally, some examples of the practical application of T cell epitope identification are provided, showing how epitopes have been valuable for deriving novel immunological insights in the context of the immune response to various pathogens and allergens.Caffeine is a common stimulant consumed daily worldwide and available in a wide variety of over-the-counter formulations. It is a mild central nervous system stimulant when used in recommended doses. However, it can be fatal if taken as an intentional or accidental overdose. We report a case of a 48-year-old lady with depression and post-traumatic stress disorder who consumed a significant overdose of caffeine, triggered by the stress that she had contracted coronavirus disease 19. This led to significant cardiovascular and central nervous system toxicity. The condition was identified early and managed appropriately with early β-blockers and gastric decontamination, which saved her life. There are few studies with regard to such modalities on treatment for caffeine overdose; our patient responded rapidly and favourably to the treatment. Why should an emergency physician be aware of this? Caffeine overdose is uncommon but one that clinicians should be aware of. Early identification and intervention with β-adrenergic antagonists and activated charcoal is paramount in caffeine toxicity.
Compared to the general population, persons with mental disorders are overrepresented in prison. In a study carried out in Picardy (northern France) in 2017, a quarter of those entering prison had had contact with a psychiatric service prior to their incarceration. Since to our knowledge no work on this subject has been published in France, we conducted a retrospective study, the main objective of which was to propose an estimate measure of incarceration likelihood in people with mental disorders.
Using data from a psychiatric hospital discharge database (Recueil d'informations médicalisé en psychiatrie, RimP), we searched for patients aged 18 and older who had received psychiatric care (except for those who were incarcerated at baseline) at the Oise psychiatric hospital in 2015-2016 and identified those who had also been registered by the psychiatric care tool (DSP) in liaison with the same hospital. As a marker of incarceration, registration was the event to be investigated. Survival analyses (Kaplan-Mever the same period.
Our study confirms the pronouncedly high incarceration rate of people with mental disorders. Scheduled to begin in 2020, coding in the RimP of a single nationwide patient identifier for all the procedures and stays described will allow the generalized measurement by means of the proposed indicator throughout France.

Our study aimed to evaluate the relationship between electrodiagnostic study (EDS) severity and utilization of treatments for carpal tunnel syndrome (CTS) as well as the duration of time between EDS and carpal tunnel release (CTR).
We conducted a retrospective medical chart review at a single tertiary hand center to evaluate CTS-related care that patients received after EDS. We recorded patient age, sex, race/ethnicity, insurance type, CTS-related surgical and nonsurgical healthcare utilization after EDS testing, and number of days between EDS and CTR.
Among all patients with an eventual diagnosis of CTS who received EDS (n= 210), nearly half had normal or mild severity (23%, n= 48; and 28%, n= 58, respectively) and the other half had moderate or severe EDS findings (26%, n= 55; and 23%, n= 49, respectively). Patients with severe findings had the highest rate of receiving surgery (53%) compared with patients with mild and moderate findings (33% vs 46%, respectively). zeomycin Among the patients who received CTR (n= 73), patients with severe EDS findings had the shortest time to CTR (59.5 days; interquartile range [IQR], 30-81), compared with mild severity (170 days; IQR, 87-415) and moderate severity (77 day; IQR, 42-292). Moderate and severe EDS findings were associated with significantly higher odds of receiving CTR in adjusted analyses (odds ratio, 2.48, 95% confidence interval, 1.04-5.93 and odds ratio 3.79, 95% confidence interval, 1.51-9.50, respectively) compared with patients with mild EDS findings. However, the odds of receiving steroid injection and hand therapy/orthosis were not significantly different based on severity.
Electrodiagnostic study severity had a direct relationship to the probability of receiving surgery but did not correlate with use of nonsurgical treatment. The study findings signal a need to evaluate the value of nonsurgical treatments in patients with severe EDS findings.

The differences in the expression profiles of colonic miRNAs between β-lactoglobulin (β-Lg) allergic mice and normal mice were analyzed to investigate the important role of the miRNA regulation mechanism in the pathogenesis of cow's milk allergy.
The present study performed Illumina sequencing to characterize the miRNA profile changes in mouse colon responding to β-Lg challenge. Target genes were predicted by TargetScan 50 and miRanda 3.3a algorithms and assessed by GO and KEGG analysis. The expression levels of selected miRNAs and cytokine production were verified by cell transfection and quantitative RT-PCR.
A total of 15 miRNAs were diversely expressed between the colon of the normal and β-Lg-sensitized mice (P < 0.05, fold change of >1.50 or <0.67), including six up-regulated miRNAs and nine down-regulated miRNAs, among which seven miRNAs were validated using qRT-PCR. GO enrichment and KEGG pathway analyses further revealed that biological process, protein binding, cytoplasm and the pathways of cancer were significantly enriched, which were closely connected to the allergic inflammation development.
