Multicenter Study Observational Study
High serum sCD40L during the first week of malignant middle cerebral artery infarction and mortality.
Higher circulating soluble cluster of differentiation 40 ligand (sCD40L) levels at admission of an ischemic stroke have been found in nonsurvivor than in survivor patients. The objectives of this study were to determine whether serum sCD40L levels during the first week of a severe malignant middle cerebral artery infarction (MMCAI) are higher in nonsurvivor than in survivor patients and whether they could be used as biomarker of mortality prediction. ⋯ The findings that nonsurvivors showed higher serum sCD40L levels during the first week of MMCAI than did survivors and that serum sCD40L levels during the first week of MMCAI could be used as a mortality predictor biomarker are 2 novel findings.

Atypical and anaplastic meningiomas, unlike their benign counterparts, are highly aggressive, locally destructive, and likely to recur after treatment. These diseases are difficult to definitively treat with traditional radiotherapy without injuring adjacent brain parenchyma. The physical properties of ion radiotherapy allows for treatment plans that avoid damaging critical neural structures. The objectives of this systematic review were to evaluate the use and efficacy of ion radiotherapy in the treatment of atypical and anaplastic meningiomas. ⋯ Proton and carbon ion radiotherapy maintain comparable rates of local control to conventional photon therapy and allow for more targeted treatment plans that may limit excess radiation damage. Although additional prospective trials are needed, ion therapy represents a burgeoning field in the treatment of atypical and anaplastic meningiomas.

Multicenter Study
Meteorological variation is a predisposing factor for aneurismal subarachnoid hemorrhage: A 5-year multicenter study in Fuzhou, China.
The climatic characteristics of aneurysmal subarachnoid hemorrhage (aSAH) have been reported, but consensus has not yet been reached. It is of great significance to elucidate the relationships between meteorological variation and aSAH in regions with specific climate patterns. We analyzed the occurrence of aSAH in the capital city of Fujian Province, China, through a multicenter, 5-year study, and aimed to reveal the meteorological influences on aSAH in the coastal city of eastern Fujian under the subtropical marine monsoon condition. ⋯ Cold and excessive atmospheric pressure are triggers for the occurrence of aSAH; March in spring and December in winter are the predominant onset periods in Fuzhou.

To compare the cervical sagittal balance and surgical outcomes between anterior cervical discectomy and fusion (ACDF) and hybrid decompression and fusion (HDF; 1-level corpectomy combined with 1-level discectomy) for consecutive 3-level cervical spondylotic myelopathy (CSM). ⋯ Both ACDF and HDF were safe and effective for the treatment of 3-level CSM. ACDF showed superiority to HDF in terms of less blood loss, shorter operation time, and better postoperative sagittal balance.

Case Reports
Linac-based fractionated stereotactic radiotherapy with a micro-multileaf collimator for brainstem metastasis.
To assess the neuroimaging and clinical outcomes in patients with brainstem metastasis (BSM) treated with linac-based fractionated stereotactic radiotherapy (fSRT) with a micro-multileaf collimator. ⋯ Linac-based fSRT with a micro-multileaf collimator delivered in the doses of 24-40 Gy in 7-13 fractions is a safe and effective local therapy for patients with BSM.
