As the elderly population increases, the incidence of lumbar fusion is increasing, and there has been increasing interest in rapid rehabilitation and functional recovery after surgery. Enhanced recovery after surgery program and multimodal pain control methods can reduce the complications and allow rapid recovery. Various methods have been used to increase the fusion.

Lumbar decompressive surgery is a standard surgery for lumbar spinal stenosis. Many surgical techniques have been introduced, ranging from open surgery to percutaneous procedures. Minimally invasive techniques are preferred because of the less postoperative pain and shorter hospital stay. Uniportal percutaneous endoscopic decompression has technical difficulties due to the narrow field. Biportal percutaneous endoscopic decompression is a satisfactory technique that can compensate for the shortcomings and provide sufficient decompression.

Background: Denosumab (DEN) and zoledronic acid (ZOL) currently represent the most potent antiresorptive agents for the treatment of osteoporosis. Despite similar effects on bone resorption, these agents have distinct mechanisms of action. The objective of this study was to compare the effect of DEN and ZOL after two-year administration on bone mineral density (BMD), trabecular bone score (TBS), bone turnover markers, and persistence. Methods: A total of 585 postmenopausal women with osteoporosis who did not use osteoporosis medications were retrospectively reviewed. 290 patients were administered 60 mg DEN subcutaneously every 6 months from 2017 to 2018, and 295 patients were treated with 5 mg ZOL intravenously yearly from 2015 to 2017. BMD, TBS, and C-terminal crosslinking telopeptide of type 1 collagen (CTX) measurements were obtained at baseline and two-year after DEN injection or ZOL infusion. Results: After two-year follow-up, 188 patients in the DEN group and 183 patients in the ZOL group were compared. BMD change from baseline at two years was significantly greater in the DEN group compared with the ZOL group (P < 0.001). The changes of TBS in the DEN group were statistically significant compared with baseline (P < 0.001) and the ZOL group (P < 0.001). The DEN group led to significantly greater reduction of CTX compared with ZOL group (P = 0.041). Conclusion In postmenopausal women with osteoporosis, DEN was associated with greater BMD increase at all measured skeletal sites, greater increase of TBS, and greater inhibition of bone remodeling compared with ZOL.

The comparative analysis of the human and primate genomes including the chimpanzee can reveal unique types of information impossible to obtain from comparing the human genome with the genomes of other vertebrates. PrimateDB is an open depository server that provides primate genome information for the comparative genome research. The database also provides an easy access to variable information within/between the primate genomes and supports analyzed information, such as annotation and retroelements and phylogeny. The comparative analyses of more primate genomes are also being included as the long-term objective.

OBJECTIVE: Malposition of central venous catheterization (CVC) may cause vascular related complications and catheter dysfunctions. The aim of this study was to reduce the malposition rate of CVC by repositioning the malposition after confirming the location of the guide-wire with ultrasound (US) guidance. METHODS: This research assessed the before study (group A) from January to December 2016 and after study (group B) from January to December 2017 in the emergency department. CVCs were performed using the anatomical landmark technique (group A) and US guided technique (group B). In group B, if the guided-wire was misplaced, it was drawn back and repositioned under US guidance. The final location of the catheter tip was confirmed by chest X-ray. The rate of malposition before and after repositioning of the two groups was compared. RESULTS: The subjects were group A (694 cases) and group B (619 cases) with a total of 1,313 patients. The rate of malposition before repositioning of the two groups were 16 cases (2.3%) and 13 cases (2.1%), respectively, and no statistically significant difference was observed (P>0.05). In group B, there were 10 cases (1.6%) of guidewire malposition that was identified and three cases (0.5%) of catheter malposition could not be identified under US examination. The malpositioned guidewires were all corrected by repositioning under ultrasound guidance. The rate of malposition after repositioning of the two groups were 2.3% (n=16) and 0.5% (n=3), respectively, and a statistically significant difference was observed (P=0.009). CONCLUSION: With US guidance, confirming the location and repositioning CVC guidewire can reduce the malposition rate in CVCs.
