OBJECTIVE Arab populations lack data related to nutritional assessment in children with autism spectrum disorders (ASDs), especially micronutrient deficiencies such as folate and vitamin B12. METHODS To assess the dietary and serum folate and vitamin B12 statuses, a hospital-based case-control study was conducted in 80 Omani children (40 children with ASDs versus 40 controls). RESULTS The A...

Protein misfolding and proteostasis decline is a common feature of many neurodegenerative diseases. However, modeling the complexity of proteostasis and the global cellular consequences of its disruption is a challenge, particularly in live neurons. Although conventional approaches, based on population measures and single "snapshots", can identify cellular changes during neurodegeneration, they...

Experimental interventions that reduce reproduction cause an extension in lifespan. In invertebrates, such as Caenorhabditis elegans, the aging of the soma is regulated by signals from the germline. Indeed, ablation of germ cells significantly extends lifespan. Notably, germline-deficient animals exhibit heightened resistance to proteotoxic stress. This phenotype correlates with increased poten...

BACKGROUND Problem alcohol drinking in homeless and vulnerably housed people can lead to malnutrition, which is associated with complications such as alcohol-related brain damage. Homeless alcohol drinkers are likely to have worse health outcomes and different nutritional needs compared with housed alcohol-drinking persons. It is not clear whether interventions to improve nutritional status in ...

Micronutrient deficiencies are common in HIV/AIDS, resulting from both malabsorption and virally-caused depletion. Beta carotene and selenium deficiencies, two of the most common nutrient deficiencies, are important due to their dual function as nutrients necessary for immune modulation and as antioxidants. Beta carotene deficiencies are common in all stages of HIV/AIDS and may signal malabsorp...

DATA SOURCES All applications for which FDA's Center for Drug Eva...

CONTEXT Accuracy is an important feature of any diagnostic test. There has been an increasing awareness of deficiencies in study design that can create bias in estimates of test accuracy. Many pathologists are unaware of these sources of bias. OBJECTIVE To explain the causes and increase awareness of several common types of bias that result from deficiencies in the design of diagnostic accura...
