Localized Inflammation in Dengue Vaccine-Induced Skin Rash Is Not Associated with Continuous Presence of Dengue Virus Genome.

Vaccination with the tetravalent live-attenuated dengue virus (DENV) vaccines TV003 and TV005 causes a mild, relatively localized erythematous maculopapular skin rash in most dengue-naïve vaccinees. Human challenge model DENV strains, DENV2Δ30 and DENV3Δ30, trigger a confluent skin rash over most of the body in most unvaccinated participants. To determine the etiology of these rashes, we performed in situ hybridization for DENV genome and assessed cellular infiltration by H&E staining in skin biopsies from humans infected with live-attenuated dengue vaccine DENV2Δ30 or DENV3Δ30 challenge strains.

Repeated use of hospital-based services and delayed hospital discharges in a population-based cohort of autistic adults in Canada.

We know that autistic people have more health problems and are more likely to go to the emergency department and get hospitalized than other people, but we know less about the problems they have once they get to the hospital. In this study, we looked at all autistic adults in Ontario and compared them to adults who were not autistic and to adults who had other kinds of developmental disabilities to see who came back to the emergency department in the month after an emergency department visit, who got re-hospitalized in the month after being sent home from hospital, and who stayed in the hospital longer than they needed to because there was no place appropriate for them to go to. We found that both autistic males and females were more likely to have these things happen to them than the same age- and sex-matched adults who did not have developmental disabilities.

Precision arbovirus serology with a pan-arbovirus peptidome.

Arthropod-borne viruses represent a crucial public health threat. Current arboviral serology assays are either labor intensive or incapable of distinguishing closely related viruses, and many zoonotic arboviruses that may transition to humans lack any serologic assays. In this study, we present a programmable phage display platform, ArboScan, that evaluates antibody binding to overlapping peptides that represent the proteomes of 691 human and zoonotic arboviruses.

Beyond Diagnosis and Comorbidities-A Scoping Review of the Best Tools to Measure Complexity for Populations with Mental Illness.

Beyond the challenges of diagnosis, complexity measurement in clients with mental illness is an important but under-recognized area. Accurate and appropriate psychiatric diagnoses are essential, and further complexity measurements could contribute to improving patient understanding, referral, and service matching and coordination, outcome evaluation, and system-level care planning. Myriad conceptualizations, frameworks, and definitions of patient complexity exist, which are operationalized by a variety of complexity measuring tools.

Lineage-Selective Dependencies in Pediatric Cancers.

The quest for effective cancer therapeutics has traditionally centered on targeting mutated or overexpressed oncogenic proteins. However, challenges arise in cancers with low mutational burden or when the mutated oncogene is not conventionally targetable, which are common situations in childhood cancers. This obstacle has sparked large-scale unbiased screens to identify collateral genetic dependencies crucial for cancer cell growth.
