Can the “Current View” show that autistic young people referred to mental health services have more comorbidities and complex needs?

Purpose Autistic young people have health and care needs that may benefit from a multi-agency intervention. The “Current View” tool is routinely used in England to profile the needs of young people referred to mental health services. This study aims to examine associations between comorbidities and complex needs in autistic and non-autistic young people to assess the multifaceted needs of autistic young people. Design/methodology/approach A cohort study was conducted using data from the electronic patient record, comparing autistic and non-autistic young people to see which items in the four “Current View” tool categories were associated with autistic young people. Findings Issues associated with autistic young people were: “community issues”, “attainment issues” and “deemed child in need” (all p < 0.001). Autistic young people scored significantly more items (p < 0.05) in the categories complexity/contextual/educational factors. Comorbidities associated with autistic young people included anxiety, “behavioural difficulties”, “peer relationship difficulties” and “self-care issues” (all p < 0.001). There was an association with increased comorbidities and complexity factors in autistic young people which suggests increased support from agencies may be beneficial. Originality/value Few studies have used data in the “Current View” tool to assess young people referred to services. More use could be made of this data for planning and delivering services

Platelet Microbicidal Protein 1: Structural Themes of a Multifunctional Antimicrobial Peptide

Mammalian platelets release platelet microbicidal proteins (PMPs) as components of their antimicrobial armamentarium. The present studies defined the structure of PMP-1 and examined its structure-activity relationships. Amino acid sequencing and mass spectroscopy demonstrated that distinct N-terminal polymorphism variants of PMP-1 isolated from nonstimulated or thrombin-stimulated platelets arise from a single PMP-1 propeptide. Sequence data (NH(2)-[S]D(1)DPKE(5)SEGDL(10)HCVCV(15)KTTSL(20) . . .) enabled cloning of PMP-1 from bone marrow and characterization of its full-length cDNA. PMP-1 is translated as a 106-amino-acid precursor and is processed to yield 73-residue (8,053 Da) and 72-residue (7,951-Da) variants. Searches with the BLAST program and sequence alignments demonstrated the homology of PMP-1 to members of the mammalian platelet factor 4 (PF-4) family of proteins. On the basis of phylogenetic relatedness, congruent sequence motifs, and predicted three-dimensional structures, PMP-1 shares the greatest homology with human PF-4 (hPF-4). By integration of its structural and antimicrobial properties, these results establish the identity of PMP-1 as a novel rabbit analogue of the microbicidal chemokine (kinocidin) hPF-4. These findings advance the hypothesis that stimuli in the setting of infection prompt platelets to release PF-4-class or related kinocidins, which have structures consistent with their likely multiple roles that bridge molecular and cellular mechanisms of antimicrobial host defense

Up-regulation of collagen and tissue inhibitors of matrix metalloproteinase in colonic diverticular disease

Purpose: Thickening of the muscularis propria is a key pathologic feature of colonic diverticulosis but its cause is unknown. This study was designed to investigate the role of collagens, matrix metalloproteinases, and tissue inhibitor of metalloproteinases in colonic diverticulosis.Methods: Collagen content was determined by Sircol Collagen Assay and standard van Gieson staining. Messenger-RNA expression for matrix metalloproteinases and tissue inhibitor of metalloproteinase was analyzed by quantitative competitive reverse transcription polymerase chain reaction. Immunohistochemical staining was performed to localize tissue inhibitor of metalloproteinases in sections.Results: In mucosa and submucosal layer, complicated diverticular disease samples had a higher collagen content than uncomplicated disease, which in turn had higher levels than controls. There was an 18-fold increase in tissue inhibitor of metalloproteinase-1 mRNA, and a threefold increase in tissue inhibitor of metalloproteinase-2 mRNA in complicated diverticulosis compared with controls. In the muscularis propria, the amount of total soluble collagen also was higher in both uncomplicated and complicated diverticulosis samples than in the controls. Tissue inhibitor of metalloproteinase-1 and metalloproteinase-2 mRNA was significantly increased in diverticulosis compared with controls. Macrophage-like and fibroblast-like cells stained strongly positive for tissue inhibitor of metalloproteinases in the submucosa, serosa, and muscularis propria and in areas around the blood vessels.Conclusion: Colonic diverticulosis is associated with altered collagen content and tissue inhibitor of metalloproteinases expression. These factors may play a role in remodeling the gut wall in this condition

The Hyaluronidase, TMEM2, Promotes ER Homeostasis and Longevity Independent of the UPRER

Cells have evolved complex mechanisms to maintain protein homeostasis, such as the UPRER, which are strongly associated with several diseases and the aging process. We performed a whole-genome CRISPR-based knockout (KO) screen to identify genes important for cells to survive ER-based protein misfolding stress. We identified the cell-surface hyaluronidase (HAase), Transmembrane Protein 2 (TMEM2), as a potent modulator of ER stress resistance. The breakdown of the glycosaminoglycan, hyaluronan (HA), by TMEM2 within the extracellular matrix (ECM) altered ER stress resistance independent of canonical UPRER pathways but dependent upon the cell-surface receptor, CD44, a putative HA receptor, and the MAPK cell-signaling components, ERK and p38. Last, and most surprisingly, ectopic expression of human TMEM2 in C.&nbsp;elegans protected animals from ER stress and increased both longevity and pathogen resistance independent of canonical UPRER activation but dependent on the ERK ortholog mpk-1 and the p38 ortholog pmk-1
