001). SD was higher using a single blood pressure measurement per visit (compared with the mean of 3 measurements
per visit P<.001) and with automated vs manual devices (P<.001). In summary, number and timing of visits and device used to measure blood pressure influence VVV and need to be considered when designing, interpreting, and comparing studies.

“Policy makers and researchers increasingly look to systematic reviews as a means of connecting research and evidence more effectively with policy. Based on Australian research into rural and remote Smoothened Agonist in vitro primary health care services, we note some concerns regarding the suitability of systematic review methods when applied to such settings. It suggests that rural and other health services are highly complex and researching them is akin to dealing with “wicked” problems. It proposes that the notion of “wicked” problems may inform our understanding of the issues and our choice of appropriate methods to inform health service policy. Key issues including the complexity of health services, methodological limitations of traditional reviews, selleck compound the nature of materials under review, and the importance
of the service context are highlighted. These indicate the need for broader approaches to capturing relevant evidence. Sustained, collaborative synthesis in which complexity, ambiguity and context is acknowledged is proposed as a way of addressing the wicked nature of these issues.

“Background and Objectives: Bone vascularization is a key factor in the bone healing process following X-ray irradiation. Preserving the vascular network from X-ray induced injury is a relevant approach in the promotion of bone healing. Previously, we developed a protocol of laser preconditioning (810 nm Bromosporine in vivo diode laser, 36 J/cm(2)) prior to X-ray radiation (18.75 Gy) which protects
the bone vascular network from deleterious effects of X-ray radiation. The aim of this present work is to characterize the effects of laser preconditioning on the bone through a morphological analysis of vascular parameters.\n\nMaterials and Methods: Digital images of the vascular plexus were taken through an optical bone chamber which was implanted onto the calvaria of rabbits. Bespoke software was used for the quantification of the vessels (classified in four groups according to their diameter), vessel length, and number of nodes at weeks 0, 4, and 8. Twenty rabbits were divided into four groups: control group #1(n = 5); laser group #2 (n = 5). X-ray radiation group #3 (n = 5), laser preconditioning 24 hours prior to X-ray radiation group #4 (n = 5).\n\nResults: The bone vascular network was stable for groups #1 and #2. Statistical analysis showed a significant reduction of each observed vascular parameter for groups #3 and #4.
