Dispersion of free-falling saliva droplets by two-dimensional vortical flows.

Abstract: The dispersion of respiratory saliva droplets by indoor wake structures may enhance the transmission of various infectious diseases, as the wake spreads virus-laden droplets across the room. Thus, this study analyzes the interaction between vortical wake structures and exhaled multi-component saliva droplets. A self-propelling analytically described dipolar vortex is chosen as a model wake flow, passing through a cloud of micron-sized evaporating saliva droplets.

Autoimmune Disease Classification Based on PubMed Text Mining.

Autoimmune diseases (AIDs) are often co-associated, and about 25% of patients with one AID tend to develop other comorbid AIDs. Here, we employ the power of datamining to predict the comorbidity of AIDs based on their normalized co-citation in PubMed. First, we validate our technique in a test dataset using earlier-reported comorbidities of seven knowns AIDs.

Promoting advance care planning (ACP) in community health clinics in Israel: Perceptions of older adults with pro-ACP attitudes and their family physicians.

Objective: We examined barriers and facilitators to patient-family physician discussions in Israel about advance care planning, including preparation of an advance directive by adults over age 65, as part of a program in two community health clinics which afforded family physicians the opportunity to dedicate time to such discussions with patients. To the best of our knowledge, the program is the first of its kind in Israel.

Method: We used thematic analyses of qualitative data collected through 22 interviews with patients with pro-advanced care planning attitudes and three focus groups with eleven family physicians.

Dipeptidyl-peptidase IV inhibitor (DPP4i) confers increased odds of bullous pemphigoid even years after drug initiation.

The timing pattern in which dipeptidyl-peptidase IV inhibitors (DPP4i) confer the risk of bullous pemphigoid (BP) is unknown. To investigate the odds of BP following exposure to DPP4i and to perform a duration-response analysis evaluating the risk of BP in relation to the duration of exposure to the culprit drug. A population-based nested case-control study was performed comparing diabetic patients with BP (n = 1458) with age-, sex- and ethnicity-matched diabetic control subjects (n = 6051) with respect to the prevalence of exposure to DPP4i.

Food Attention Bias: appetite comes with eating.

Objective: Cognitive interventions may be effective in weight loss. The purpose of this study was to assess if cognitive reappraisal (CR; reframing the meaning of a stimulus in order to change the resulting emotional response), can reduce food attentional bias (FAB) using the Visual Dot Probe (VDP) paradigm.

Method: 126 participants (age 27 ± 5.
