Bong Jun Kim et al presented the role of epigenetic changes in patients with delayed cerebral ischemia (DCI) following subarachnoid hemorrhage (SAH). It was found that biological process and hub genes were closely associated with DCI in patients with SAH using various bioinformatics tools. It was shown that hypermethylated hub genes can be feasibly used to accurately diagnose DCI that requires timely treatment. A better understanding of the biological and metabolic processes in DCI by bioinformatics analysis might open a new view to more effective management of this fearful complication following SAH. Akaworn Mahatthanatrakul et al assessed the degree of indirect decompression of lumbar foraminal stenosis and the effect of position of oblique lumbar Interbody fusion (OLIF) cage. OLIF is a technique of recent interest, surgeons may wonder how to get the optimal decompression. It was demonstrated that the more posterior position of the cage is helpful for better foraminal decompression, whereas central canal decompression was not affected. It was also shown that the side of the cage does not affect the degree of decompression of either left or right foramen. It might provide a useful guide to perform OLIF for better clinical and radiological outcomes. We hope our newsletter attracts your interest. Any comments and suggestions are always welcome.
