A summary of all interviews and focus group was made to identify overall meaning [25]. Content analysis of the transcriptions was performed concomitantly by constant back

and forth from codes and categories to raw data (verbatim excerpts). A comprehensive coding grid that evolved as new categories linked Talazoparib mw to the study theme emerged from the data was used. The coded content relating to study theme (ethical issues) was then grouped into categories (by JB and AR) and discussed with the research team until consensus was reached about essential meanings. Quotes were identified based on the following system: R (relative), S (stroke client), ID number, T1 (Time 1), T2 (Time 2). Characteristics of participants at Phase 1 are presented in Table 2. Relatives (n = 25) were aged between 31 and 72 years,

nine of whom were interviewed at both times (following discharge from T1 [acute care] and T2 [rehabilitation]) for a total of 34 interviews. Stroke clients (n = 16) were aged between 37 and 76 years, ten of whom participated at T1 and T2 (n = 26 interviews). Participants Ceritinib in the focus group (Phase 2) for relatives (n = 5) were aged between 43 and 66 years, three of whom were women. Participants in the stroke client focus group were mainly men (n = 3/4), while participants in the health professional focus group were mainly women (n = 4/5). For the latter, a variety of disciplines were represented from throughout the continuum of stroke care (acute care, in-patient rehabilitation, out-patient rehabilitation), including a nurse, a physiotherapist, a speech language pathologist, a social worker, and a specialized educator, while the two facilitators were occupational therapists. Four main themes relating to ethical issues emerged from the interviews:

(1) overemphasis of caregiving role with an unclear legitimacy of relative to also be a client; (2) communication as a key issue to foster respect and a family-centered approach; (3) availability and attitudes of health professionals as a facilitator or a barrier to a family-centered approach; and (4) BIBF1120 constant presence of relatives as a protective factor or creating a perverse effect. If there was an overarching theme, it would be about the tension between the dual roles of relatives with a predominance of the caregiving role mainly as being a source of information “Let me tell you, sometime I had the feeling they were not communicating the information to each other because they were asking over and over the same questions” (R10T1) and a blurred legitimacy for relatives to receive services as a client “…I told myself, I better stop asking questions, because I feel, I feel I’m getting on their nerves … I didn’t want to become irritating, you know” (R7T1).

After 12 weeks of diet correction, the HFD-fed immature mice show no relative improvement in femoral BVF or other trabecular parameters, while the femoral BVF of mature mice tends to recover to that of the lean controls. The results of this study demonstrate a complex interplay between growth, aging, anatomic site and excessive dietary fat on cancellous bone homeostasis in male mice and require further study to elucidate the biological mechanisms underpinning these effects. The authors have no conflicts of interest and nothing to disclose.

“When tissue of living organisms is analyzed by highly sensitive chemical analytic methods, specific chemical elements in very minute quantities (< ppm) can be found. These so called trace elements can be essential and/or non-essential for the living organism

[1]. However, the role of many trace elements in tissues CX-5461 cell line e.g. bone is poorly understood [2]. Great efforts have been undertaken to determine the incorporated amounts of various trace elements in bone [3] and [4]. Since in general the chemical analysis is based on destructive methods, the information about the spatial distribution of the trace elements within the tissue is usually lost. Previous studies lacked spatial

distribution and merely differentiated between cortical and trabecular bone [5], [6], [7], [8], [9] and [10]. New developments in synchrotron radiation technology allow now analyzing in a non-destructive way, spatially resolved trace elements like zinc (Zn), strontium (Sr) and lead (Pb) in bone tissue. For example using synchrotron radiation induced confocal micro X-ray Thymidine kinase fluorescence analysis (SR μ-XRF) we found a highly specific accumulation of Pb and Zn in the transition zone between mineralized and nonmineralized articular cartilage compared to subchondral bone [11] and [12]. Moreover this method is also able to detect and map different elements simultaneously [13]. Zn, Sr and Pb are trace elements, present in sufficient concentrations in bone so they can be easily mapped with the multi-elemental SR μ-XRF method. Zn is an important essential trace element in multiple biological processes and a reduced intake may lead to chronic diseases [14]. Zn is also present in bone tissue and it has been reported to play an important role in bone metabolism [15], [16] and [17].
