Brief Report: Parent Perspectives on Sensory-Based Interventions for Children with Autism Spectrum Disorder

Sensory-Based Interventions (SBIs) are often recommended to enable function/participation in children with ASD. Still, there are limited studies to evaluate their effectiveness. Acceptability studies are an important step towards establishing effective interventions. We examined parents' perceptions of the uptake and acceptability of such interventions. An online survey was sent to 399 families; response rate was 39%. The most frequently therapist-recommended interventions were trampoline (54.6%), massage (47.8%), and oral-motor tools (43.8%). Highest use was reported for massage (96.3%), trampoline (89.2%) and joint compressions and brushing (89.2%). The majority of parents viewed these interventions to be very important /important, (74.8%) but barriers to their use were identified. High acceptability of SBIs was reported by parents of children with ASD.

     

Multidrug-resistant bacteria in geriatric clinics,nursing homes,and ambulant care – Prevalence and risk factors

Colonization/infection with multidrug-resistant bacteria (MDRB) such as methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and extended-spectrum beta-lactamase (ESBL) producing Enterobacteriaceae, is an increasing problem not only in hospitals but also in long-term care facilities. The aim of this study was to determine the prevalence as well as the risk factors of colonization/infection with MRSA, VRE, and ESBL producing Enterobacteriaceae in geriatric clinics, nursing homes, and ambulant care in Frankfurt am Main, Germany. 288 patients from 2 geriatric clinics (n = 46), 8 nursing homes (n = 178), and 2 ambulant care facilities (n = 64) as well as 64 staff members were screened for MDRB in the time period from October 2006 to May 2007. 58 patients (20.1%) and 4 staff members (6.2%) were colonized with MDRB. Among patients, 27 (9.4%) were colonized with MRSA, 11 (3.8%) were screened positive for VRE, and 25 (8.7%) were found to be colonized with ESBL producing Enterobacteriaceae. Prevalence of MDRB in geriatric clinics, nursing homes, and ambulant care facilities were 32.6%, 18.5%, and 15.6%, respectively. Significant risk factors for MDRB were immobility (OR: 2.7, 95% CI: 1.5–4.9; p = 0.002), urinary catheter (OR: 3.1, 95% CI: 1.7–5.9; p < 0.001), former hospitalization (OR: 2.1, 95% CI: 1.1–4.0; p = 0.033), and wounds/decubiti (OR: 2.3, 95% CI: 1.5–4.9; p = 0.03). Finally, the high level of MDRB in geriatric clinics, nursing homes, and ambulant care points to the importance of these institutions as a reservoir for dissemination.     

ER Stress During the Pubertal Growth Spurt Results in Impaired Long‐Bone Growth in Chondrocyte‐Specific ERp57 Knockout Mice

Long‐bone growth by endochondral ossification is cooperatively accomplished by chondrocyte proliferation, hypertrophic differentiation, and appropriate secretion of collagens, glycoproteins, and proteoglycans into the extracellular matrix (ECM). Before folding and entering the secretory pathway, ECM macromolecules in general are subject to extensive posttranslational modification, orchestrated by chaperone complexes in the endoplasmic reticulum (ER). ERp57 is a member of the protein disulfide isomerase (PDI) family and facilitates correct folding of newly synthesized glycoproteins by rearrangement of native disulfide bonds. Here, we show that ERp57‐dependent PDI activity is essential for postnatal skeletal growth, especially during the pubertal growth spurt characterized by intensive matrix deposition. Loss of ERp57 in growth plates of cartilage‐specific ERp57 knockout mice (ERp57 KO) results in ER stress, unfolded protein response (UPR), reduced proliferation, and accelerated apoptotic cell death of chondrocytes. Together this results in a delay of long‐bone growth with the following characteristics: (1) enlarged growth plates; (2) expanded hypertrophic zones; (3) retarded osteoclast recruitment; (4) delayed remodeling of the proteoglycan‐rich matrix; and (5) reduced numbers of bone trabeculae. All the growth plate and bone abnormalities, however, become attenuated after the pubertal growth spurt, when protein synthesis is decelerated and, hence, ERp57 function is less essential. © 2015 American Society for Bone and Mineral Research.
