Health research needs more comprehensive accessibility measures: integrating time and transport modes from open data.

Background: In this paper, we demonstrate why and how both temporality and multimodality should be integrated in health related studies that include accessibility perspective, in this case healthy food accessibility. We provide evidence regarding the importance of using multimodal spatio-temporal accessibility measures when conducting research in urban contexts and propose a methodological approach for integrating different travel modes and temporality to spatial accessibility analyses. We use the Helsinki metropolitan area (Finland) as our case study region to demonstrate the effects of temporality and modality on the results.

Evaluating the impact of distance measures on deforestation simulations in the fluvial landscapes of amazonia.

Land use and land cover change (LUCC) models frequently employ different accessibility measures as a proxy for human influence on land change processes. Here, we simulate deforestation in Peruvian Amazonia and evaluate different accessibility measures as LUCC model inputs. We demonstrate how the selection, and different combinations, of accessibility measures impact simulation results.

Adrenocortical hormonal activity in 20-year-old subjects born small or appropriate for gestational age.

Background: Altered adrenocortical activity is one suggested mechanism relating small birth size with the metabolic syndrome in adulthood. Adrenal androgen concentrations are higher in children born small (SGA) than appropriate for gestational age (AGA).

Aim: To compare adrenocortical hormonal activity between 20-year-old subjects born SGA or AGA.

Tracking serum lipid levels and the association of cholesterol concentrations, blood pressure and cigarette smoking with carotid artery intima-media thickness in young adults born small for gestational age.

Background: Small birth size is associated with increased cardiovascular disease risk, but the mediating factors are poorly understood.

Methods And Results: Serum lipids, blood pressure (BP), carotid artery intima-media thickness (CA-IMT), and brachial artery flow-mediated dilatation (BA-FMD) were studied in 70 20-year-old subjects [35 sex- and age-matched pairs born small (SGA) and appropriate for gestational age (AGA)]. The SGA subjects had higher serum levels of low-density lipoprotein (LDL) cholesterol, total/high-density lipoprotein (HDL) and LDL/HDL cholesterol ratios, and lower HDL cholesterol levels than the AGA subjects (2.
