Engaging Food Insecure Families on the Weekend to Improve Nutrition and Health.

Background: The school meals program provides food during the week, but there is limited evidence on how to address the needs of families with food insecurity (FI) on the weekend.

Objectives: We conducted a prospective mixed methods pilot study to evaluate the potential effect of a community-based program that delivers free meals to children and fresh produce to their families at different sites on weekends combined with cooking classes.

Methods: We recruited 41 parent-child dyads from the neighborhood where a new delivery site opened.

Laser photoablation of experimental post-infarction ventricular tachycardia guided by three dimensional activation mapping.

Background And Objective: The purpose of this study was to evaluate the efficacy of epicardially delivered laser energy to ablate induced ventricular tachycardia in a post-infarction canine model.

Study Design/materials And Methods: In 13 canines, the left anterior wall myocardial infarction was created. Five days later, 240 plunged electrodes were inserted into the heart.

Microwave tomography: two-dimensional system for biological imaging.

Microwave tomographic imaging is one of the new technologies which has the potential for important applications in medicine. Microwave tomographically reconstructed images may potentially provide information about the physiological state of tissue as well as the anatomical structure of an organ. A two-dimensional (2-D) prototype of a quasi real-time microwave tomographic system was constructed.

Myocardial temperatures during in vivo endocardial Nd:YAG laser irradiation.

To determine safety and efficacy of neodymium:YAG laser irradiation of the endocardium, temperatures at both the epicardium and the endocardium were recorded for thermal damage evaluation. A total of 48 coagulation lesions were created at power settings of 20 and 30 W in 20 open chest dogs by transcatheter endocardial laser irradiation. Tissue temperatures were monitored by epicardial thermography (Tepi), and by endocardial thermocouples at the catheter tip (Tprox) and 4 mm below the endocardial surface (Tdist).
