Practices Surrounding Event Photos

Sharing photos through mobile devices has a great potential for creating shared experiences of social events between co-located as well as remote participants. In order to design novel event sharing tools, we need to develop indepth understanding of current practices surrounding these so called ‘event photos’- photos about and taken during different social events such as weddings picnics, and music concert visits among others. We studied people’s practices related to event photos through in-depth interviews, guided home visits and naturalistic observations. Our results show four major themes describing practices surrounding event photos: 1) representing events, 2) significant moments, 3) situated activities through photos, and 4) collectivism and roles of participants

Diabetes, atherosclerosis, and stenosis by AI

OBJECTIVEThis study evaluates the relationship between atherosclerotic plaque characteristics (APCs) and angiographic stenosis severity in patients with and without diabetes. Whether APCs differ based on lesion severity and diabetes status is unknown.RESEARCH DESIGN AND METHODSWe retrospectively evaluated 303 subjects from the Computed TomogRaphic Evaluation of Atherosclerotic Determinants of Myocardial IsChEmia (CREDENCE) trial referred for invasive coronary angiography with coronary computed tomographic angiography (CCTA) and classified lesions as obstructive (≥50% stenosed) or nonobstructive using blinded core laboratory analysis of quantitative coronary angiography. CCTA quantified APCs, including plaque volume (PV), calcified plaque (CP), noncalcified plaque (NCP), low-density NCP (LD-NCP), lesion length, positive remodeling (PR), high-risk plaque (HRP), and percentage of atheroma volume (PAV; PV normalized for vessel volume). The relationship between APCs, stenosis severity, and diabetes status was assessed.RESULTSAmong the 303 patients, 95 (31.4%) had diabetes. There were 117 lesions in the cohort with diabetes, 58.1% of which were obstructive. Patients with diabetes had greater plaque burden (P = 0.004). Patients with diabetes and nonobstructive disease had greater PV (P = 0.02), PAV (P = 0.02), NCP (P = 0.03), PAV NCP (P = 0.02), diseased vessels (P = 0.03), and maximum stenosis (P = 0.02) than patients without diabetes with nonobstructive disease. APCs were similar between patients with diabetes with nonobstructive disease and patients without diabetes with obstructive disease. Diabetes status did not affect HRP or PR. Patients with diabetes had similar APCs in obstructive and nonobstructive lesions.CONCLUSIONSPatients with diabetes and nonobstructive stenosis had an association to similar APCs as patients without diabetes who had obstructive stenosis. Among patients with nonobstructive disease, patients with diabetes had more total PV and NCP.Cardiolog

The relationship between bone density and incident vertebral fracture in men and women

Bone mineral density (BMD) is an important predictor of future fracture risk in women; however, there are few prospective data in men. The aim of this analysis was to determine whether there are differences in the relationship between BMD and incident vertebral fracture in men and women. Men and women were recruited from population-based registers in 21 European centers. Those recruited were interviewed and had spinal radiographs performed. The radiographs were assessed morphometrically and prevalent vertebral deformity was defined using the McCloskey-Kanis method. Repeat spinal radiographs were performed at a mean of 3.8 years after the baseline radiographs. Incident fractures were defined using a combination of the point prevalence and 20% reduction in vertebral height (plus a 4-mm reduction in absolute height) criteria. BMD measurements were made in a subsample of those recruited. Poisson regression was used to explore the influence of gender, age, prevalent deformity, and BMD on the incidence of vertebral fracture. Thirty-four hundred sixty-one men and women had both paired spinal radiographs and bone density measurements performed. BMD at the spine and femoral neck was higher in men than in women. After adjusting for age, the risk of incident vertebral fracture was greater in women than in men (relative risk [RR] = 2.3; 95% CI, 1.5-3.6) and increased by a factor of 1.4 (95% CI, 1.2-1.8), 1.5 (95% CI, 1.2-1.8), and 1.6 (95% CI, 1.3-1.9) per decrease of 0.1 g/cm2 in BMD at the spine, femoral neck, and trochanter, respectively. After adjusting for BMD at the spine or trochanter, the gender difference in the predicted age-specific incidence of vertebral fracture was no longer significant (RR = 1.1 and 95% CI, 0.6-1.9 at the spine; RR = 1.5 and 95% CI, 0.8-2.7 at the trochanter), although it persisted after adjusting for femoral neck BMD (RR = 1.9; 95%CI, 1.1-3.3). The presence of a prevalent vertebral deformity was a strong risk factor for future vertebral fracture, although the strength of the association was reduced after adjustment for age, sex, and spine BMD. However, adjustment for the presence of a baseline vertebral deformity did not alter the main findings. In conclusion, at a given age and spine (although not femoral neck) bone density, the risk of incident vertebral fracture is similar in men and women. Incident vertebral fractures are more common in women than men because at any age their spine BMD is lower
