Preliminary results of the austrian national registry with the novel iCover bridging stentgraft in fenestrated endovascular aortic repair
CONCLUSION: The iCover represents a feasible BSG for fEVAR with an excellent safety profile and technical success rate in the early phase. Prudent post-dilatation and monitoring of the proximal and distal stent ends can potentially further improve outcome. Longer follow-up series are necessary.PMID:38627118 | DOI:10.1016/j.asjsur.2024.04.006 (Source: Asian Journal of Surgery)

A comparative in vitro and in vivo analysis of the impact of copper substitution on the cytocompatibility, osteogenic, and angiogenic properties of a borosilicate bioactive glass
J Biomed Mater Res A. 2024 Apr 15. doi: 10.1002/jbm.a.37721. Online ahead of print.ABSTRACTThe 0106-B1-bioactive glass (BG) composition (in wt %: 37.5 SiO2, 22.6 CaO, 5.9 Na2O, 4.0 P2O5, 12.0 K2O, 5.5 MgO, and 12.5 B2O3) has demonstrated favorable processing properties and promising bone regeneration potential. The present study aimed to evaluate the biological effects of the incorporation of highly pro-angiogenic copper (Cu) in 0106-B1-BG in vitro using human bone marrow-derived mesenchymal stromal cells (BMSCs) as well as its in vivo potential for bone regeneration. CuO was added to 0106-B1-BG in exchange for CaO, result...

Six-year progression of medically treated infective aortitis
CONCLUSIONS: Infective aortitis with mycotic aneurysms is usually treated surgically due to the significant risk of rupture in the acute period. This case suggests that if the acute infective period is passed, the aneurysmal disease stabilises and does not progress.PMID:38626935 | DOI:10.1177/17085381241248724 (Source: Vascular)

Ethmoid Osteoblastoma: A Case Report and Pooled Analysis of Cases
We present a case of osteoblastoma in a 13-year-old boy affecting the ethmoid sinus, which manifested as exophthalmos. A computed tomography scan revealed an expansive lesion in the right ethmoid sinus, causing compression and displacement of the orbital contents to the right. The lesion exhibited a mix of ground glass opacity and dense bone. On magnetic resonance imaging, the less dense areas of the tumor showed strong enhancement, while the densely sclerotic regions appeared as signal voids on all imaging sequences. A combined transorbital and transnasal approach was performed to remove the tumor. Histologically, the tum...

Efficacy of sentinel lymph-node biopsy after neoadjuvant chemotherapy in clinically axilla node-negative patients
ConclusionsAxillary lymph-node dissection may not be necessary for patients with cNO confirmed by physical and radiological examination using positron emission tomography (PET) computed tomography (CT), and breast magnetic resonance imaging (MRI) after NACT, if ≥ three negative SLNB are removed. Further studies are needed to confirm our findings. (Source: Surgery Today)

Association of clinical outcome and imaging endpoints in extensive ischemic stroke —comparing measures of cerebral edema
ConclusionEV might serve as an imaging biomarker of ischemic edema in future studies, as it is applicable to infarcts of all volumes and predicts MI and VPCO in patients with large infarcts with the same accuracy as MLS.Clinical relevance statementUtilization of edema volume instead of midline shift as an edema parameter would allow differentiation of patients with large and small infarcts based on the extent of edema, with possible advantages in the prediction of treatment effects, complications, and outcome.Key Points• CT densitometry–based absolute edema volume challenges midline shift as current gold standard measu...
