Linear unmixing protocol for hyperspectral image fusion analysis applied to a case study of vegetal tissues.

Hyperspectral imaging (HSI) is a useful non-invasive technique that offers spatial and chemical information of samples. Often, different HSI techniques are used to obtain complementary information from the sample by combining different image modalities (Image Fusion). However, issues related to the different spatial resolution, sample orientation or area scanned among platforms need to be properly addressed.

Onsets of complications and revisions are not increased after simultaneous bilateral unicompartmental knee arthroplasty in comparison with unilateral procedures.

Purpose: The advantages of simultaneous bilateral procedures in joint arthroplasty have been widely described for in total joint replacements of both the hip and the knee. In contrast, unicompartmental knee arthroplasties, despite their effectiveness in pain relieving and functional improvement, are underinvestigated in these terms. The purpose of this study is to assess the possible benefits and risks of bilateral simultaneous knee replacements, in comparison with unilateral procedures.

Simultaneous bilateral total hip arthroplasties do not lead to higher complication or allogeneic transfusion rates compared to unilateral procedures.

Purpose: About 20 % of patients undergoing a primary total hip arthroplasty could undergo a second contralateral procedure within five years. The possibility to perform simultaneous bilateral hip replacements instead of two-stage surgery could reduce hospitalisation time and patient management costs, but concerns exist because of risks related to massive blood loss and possible increase in complication rates. The purpose of this study is to assess the veracity of these concerns.
