A Systematic Review of Family Functioning in Families of Children on the Autism Spectrum

This article aims to review the literature on family functioning in the field of autism. The search was conducted in August 2021 in PubMed, PsycINFO, and PubPsy and sixty-two articles were included. Studies were published in English between 1980 and 2021 and provided quantitative data from validated measures of family functioning in families with an official diagnosis of autism. Results showed that family functioning appeared more problematic for families of autistic children than non-autistic ones. Difficulties were correlated with more caregiver demand and less resources. Interventional results varied. The findings highlight the importance of considering family functioning when providing care for autistic children and their families. Limitations and implications for future research are discussed.Prospero registration number: CRD42022297696.

Effects of heat treatment on mechanical properties of two nickel-chromium-based casting alloys

Mechanical and heat treatment characteristics of two nickel-chromium-based dental casting alloys were investigated. Both alloys showed rapid response to heat treatment. In their softened state the alloys lost 25 to 50% of their as-cast hardness. Elongation was 20 to 45%. Rehardening nearly restored as-cast strength, whereas elongation values remained at 10 to 17%.
