Osteoporosis is defined as bone mineral density. ⋯ Ongoing additional trials will help formulate preoperative screening recommendations, determine the optimal duration of preoperative and postoperative teriparatide treatment, and investigate its utility in men.

It is still not clear whether Gamma Knife radiosurgery (GKRS) for nonfunctional pituitary adenomas should be used as a standard adjuvant postoperative therapy or applied when there is documented progression of the remnant on follow-up magnetic resonance imaging. ⋯ Adjuvant treatment with GKRS yields the same high long-term tumor control as delayed GKRS. Neither adjuvant nor delayed GKRS induced additional neurologic complications. There is a trend that adjuvant GKRS induces less additional endocrinologic deficits compared with delayed GKRS.

Review Meta Analysis Comparative Study
Mortality and outcome comparison between brain tissue oxygen combined intracranial pressure/cerebral perfusion pressure guided therapy and intracranial pressure/cerebral perfusion pressure guided therapy in traumatic brain injury: A meta-analysis.
The combination of brain tissue oxygen and standard intracranial pressure (ICP)/cerebral perfusion pressure (CPP)-guided therapy is thought to improve traumatic brain injury (TBI) prognosis compared with standard ICP/CPP-guided therapy. However, related results of previous observational studies and recently published cohort studies and randomized controlled trials (RCTs) remain controversial. The objective of this study was to compare the effect of the combined therapy with that of standard ICP/CPP-guided therapy on mortality rate, favorable outcome, ICP/CPP, and length of stay (LOS). ⋯ Compared with standard ICP/CPP-guided therapy, brain tissue oxygen combined with ICP/CPP-guided therapy improved long-term outcomes without any effects on mortality, ICP/CPP, or LOS.

Our aim was to develop and validate a procedure-related neurologic complications (PNC) risk score for individual elderly patients with ruptured intracranial aneurysms undergoing endovascular treatment (EVT). ⋯ The PNC score can be an easily applicable tool for predicting the risk of PNC for individual elderly patients with ruptured intracranial aneurysms undergoing EVT. Our study provides large case-based evidence supporting the integration of individual clinical, lesion, and procedure characteristics to predict PNC risk.

Multicenter Study
Ryanodine receptor 1 polymorphism is not associated with aneurysmal subarachnoid hemorrhage or its clinical sequelae.
The pathophysiologic mechanisms underlying cerebral vasospasm after aneurysmal subarachnoid hemorrhage (aSAH) remain poorly understand. Ryanodine receptors (RYR) are intracellular calcium channels involved in the regulation of vascular smooth muscle cells and cerebrovascular tone and diameter. Previous work reported an association between an RYR polymorphism and cerebral vasospasm. Here, we sought to assess the impact of that RYR polymorphism on aSAH and its clinical sequelae. ⋯ Contrary to a previous report, the RYR1 SNP rs35364374 was not associated with aSAH or its clinical sequelae.
