Psychosocial determinants of oral health outcomes in young children.

Objective: To examine the social determinants of early childhood caries (ECC), one of the greatest public health risks affecting children, and examine alternative pathways of influence.

Methods: A physically healthy, socio-demographically high-risk sample of initially caries-free children, aged 1-4 years, was prospectively studied for 2 years. At 6-month intervals, assessments were made of caries presence from a standard dental exam; oral microbiology was assayed from saliva samples; oral hygiene behaviors and psychological and psychosocial risk exposure were derived from interviews and questionnaires.

'I can't relate to it': Exploring autistic and non-autistic adults' perceptions of the Australian Physical Activity and Sedentary Behaviour Guidelines.

Background: Despite sufficient physical activity (PA) being strongly associated with better health outcomes, half of the Australian population does not meet the Australian PA and Sedentary Behaviour Guidelines. This shortfall is more pronounced among autistic adults, who exhibit poorer health outcomes and lower PA levels than non-autistic adults. Despite these disparities, there is a limited understanding of how autistic and non-autistic individuals perceive and interpret the PA guidelines.

Regulatory dynamics of arginine metabolism in Staphylococcus aureus.

Staphylococcus aureus is a highly significant pathogen with several well studied and defined virulence factors. However, the metabolic pathways that are required to facilitate infection are not well described. Previous data have documented that S.
