Effects of Parent-Implemented Interventions on Outcomes of Children with Autism: A Meta-Analysis.

Children with autism spectrum disorder (ASD) have been shown to benefit from parent-implemented interventions (PIIs). This meta-analysis improved on prior reviews of PIIs by evaluating RCTs and multiple potential moderators, including indicators of research quality. Fifty-one effect sizes averaged moderately strong overall benefits of PIIs (g = 0.553), with studies having lower risk of research bias yielding lower estimates (g = 0.47). Parent and observer ratings yielded similar averaged estimates for positive behavior/social skills (g = 0.603), language/communication (g = 0.545), maladaptive behavior (g = 0.519), and to a lesser extent, adaptive behavior/life skills (g = 0.239). No other study, intervention, or participant characteristic moderated outcomes. PIIs with children with ASD tend to be effective across a variety of circumstances.

Uplifts, Respite, Stress, and Marital Quality for Parents Raising Children With Down Syndrome or Autism.

Direct, indirect, and partner effects estimated among uplifts, respite care, stress, and marital quality across mothers and fathers of children with autism spectrum disorder (n = 102) and Down syndrome (n = 111) were examined in this cross-sectional study. Parents of children with ASD who reported more uplifts and less stress individually reported better marital quality; these wives reported better marital quality as their husbands reported more uplifts and less stress. Wives with children with DS who reported more uplifts, individually along with their husbands reported less stress and better marital quality. Respite was directly associated with marital quality for parents of children with ASD and indirectly associated with marital quality for parents of children with DS with reduced individual stress. Implications are discussed.

SARS-CoV-2 Remains Infectious on Refrigerated Deli Food, Meats, and Fresh Produce for up to 21 Days.

SARS-CoV-2, the virus that causes COVID-19, has been detected on foods and food packaging and the virus can infect oral cavity and intestinal cells, suggesting that infection could potentially occur following ingestion of virus-contaminated foods. To determine the relative risk of infection from different types of foods, we assessed survival of SARS-CoV-2 on refrigerated ready-to-eat deli items, fresh produce, and meats (including seafood). Deli items and meats with high protein, fat, and moisture maintained infectivity of SARS-CoV-2 for up to 21 days. However, processed meat, such as salami, and some fresh produce exhibited antiviral effects. SARS-CoV-2 also remained infectious in ground beef cooked rare or medium, but not well-done. Although infectious SARS-CoV-2 was inactivated on the foods over time, viral RNA was not degraded in similar trends, regardless of food type; thus, PCR-based assays for detection of pathogens on foods only indicate the presence of viral RNA, but do not correlate with presence or quantity of infectious virus. The survival and high recovery of SARS-CoV-2 on certain foods support the possibility that food contaminated with SARS-CoV-2 could potentially be a source of infection, highlighting the importance of proper food handling and cooking to inactivate any contaminating virus prior to consumption.

Age, but Not Sex, Modulates Foxp3 Expression in the Rat Brain across Development.

The interconnectivity between brain development and the immune system has become an area of interest for many neuroscientists. However, to date, a limited number of known immune mediators of the peripheral nervous system (PNS) have been found to influence the development of the central nervous system (CNS). FOXP3 is a well-established mediator of regulatory T-cells in the PNS. However, the expression pattern of FOXP3 in the CNS and the PNS throughout development is unknown. To fill this void, we have characterized, in several brain regions, the developmental profile of Foxp3 for both sexes using rats. We found different patterns of Foxp3 in the CNS and PNS. In the CNS, we found Foxp3 was ubiquitously expressed, with the levels of Foxp3 varying by brain region. We also found both Foxp3 mRNA and protein levels peak during embryonic development and then steadily decrease with a peak increase during adulthood. In adulthood, the protein but not mRNA increases to the equivalent levels found at the embryonic stage of life. In the PNS, Foxp3 protein levels were low embryonically and increased steadily over the life of the animal with maximal levels reached in adulthood. Patterns observed for both the PNS and CNS were similar in males and females across all developmental timepoints. Our novel findings have implications for understanding how the neural immune system impacts neurodevelopmental disorders such as autism and schizophrenia.

A survey of clinical research coordinators in the cooperative group setting of the American College of Radiology Imaging Network (ACRIN).

RATIONALE AND OBJECTIVES: As one of the newest cooperative groups funded by the National Cancer Institute in 1999, the American College of Radiology Imaging Network (ACRIN) is interested in conducting successful clinical research programs and pursuing quality research. The ACRIN Research Associate (RA) committee was formed in 2000 and felt it important to better understand the demographics, duties, needs, and concerns of ACRIN RAs. Therefore, in 2008, the committee conducted a survey of ACRIN RAs regarding these issues. MATERIALS AND METHODS: The survey instrument consisted of 33 multiple choice questions covering demographics, salary, job satisfaction, work load, educational background, and training. RAs completed the survey electronically in June 2008. RESULTS: A total of 110 responses were received. All regions of the United States were represented. The years of experience and salary ranged widely from <1 year to 28 years and ≤$20,000 to ≥$80,000 per year. The majority of respondents held at least a bachelor's degree, with many having previous health-related clinical training; only a small percentage of respondents having had formal training in research. CONCLUSION: Our survey summarizes the demographics and educational background of the research associates within ACRIN. This may help administrators understand the needs and characteristics of RAs participating in cooperative group research. In today's environment with tight regulatory control, it may become necessary to improve educational standards or require certification through one of the professional research organizations.
