Background: and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking. Methods: This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance. Results: Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal. Conclusions The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.

INTRODUCTION: Evidence regarding the efficacy of high-flow nasal cannula (HFNC) oxygenation for preoxygenation and apnoeic oxygenation is conflicting. Our objective is to evaluate whether HFNC oxygenation for preoxygenation and apnoeic oxygenation maintains higher oxygen saturation (SpO₂) during rapid sequence intubation (RSI) in ED patients compared to usual care. METHODS: This was a multicentre, open-label, randomised controlled trial in adult ED patients requiring RSI. Patients were randomly assigned 1:1 to either intervention (HFNC oxygenation at 60L/min) group or control (non-rebreather mask for preoxygenation and nasal prongs of at least 15L/min oxygen flow for apnoeic oxygenation) group. Primary outcome was lowest SpO₂ during the first intubation attempt. Secondary outcomes included incidence of SpO₂ falling below 90% and safe apnoea time. RESULTS: One hundred and ninety patients were included, with 97 in the intervention and 93 in the control group. Median lowest SpO₂ during the first intubation attempt was 100% in both groups. Incidence of SpO₂ falling below 90% was lower in the intervention group (15.5%) compared to the control group (22.6%) (adjusted relative risk=0.68, 95% confidence interval [CI] 0.37-1.25). Post hoc quantile regression analysis showed that the first quartile of lowest SpO₂ during the first intubation attempt was greater by 5.46% (95% CI 1.48-9.45%, P=0.007) in the intervention group. CONCLUSION Use of HFNC for preoxygenation and apnoeic oxygenation, when compared to usual care, did not improve lowest SpO₂ during the first intubation attempt but may prolong safe apnoea time.

The 18 kDa translocator protein (TSPO), previously known as the peripheral benzodiazepine receptor, is predominately localized to the outer mitochondrial membrane in steroidogenic cells. Brain TSPO expression is relatively low under physiological conditions, but is upregulated in response to glial cell activation. As the primary index of neuroinflammation, TSPO is implicated in the pathogenesis and progression of numerous neuropsychiatric disorders and neurodegenerative diseases, including Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS), Parkinson's disease (PD), multiple sclerosis (MS), major depressive disorder (MDD) and obsessive compulsive disorder (OCD). In this context, numerous TSPO-targeted positron emission tomography (PET) tracers have been developed. Among them, several radioligands have advanced to clinical research studies. In this review, we will overview the recent development of TSPO PET tracers, focusing on the radioligand design, radioisotope labeling, pharmacokinetics, and PET imaging evaluation. Additionally, we will consider current limitations, as well as translational potential for future application of TSPO radiopharmaceuticals. This review aims to not only present the challenges in current TSPO PET imaging, but to also provide a new perspective on TSPO targeted PET tracer discovery efforts. Addressing these challenges will facilitate the translation of TSPO in clinical studies of neuroinflammation associated with central nervous system diseases.

Repetitive transcranial magnetic stimulation (rTMS) and intermittent theta-burst stimulation (iTBS) are evidenced-based treatments for patients with major depressive disorder (MDD) who fail to respond to standard first-line therapies. However, although various TMS protocols have been proven to be clinically effective, the response rate varies across clinical applications due to the heterogeneity of real-world psychiatric comorbidities, such as generalized anxiety disorder, posttraumatic stress disorder, panic disorder, or substance use disorder, which are often observed in patients with MDD. Therefore, individualized treatment approaches are important to increase treatment response by assigning a given patient to the most optimal TMS treatment protocol based on his or her individual profile. This literature review summarizes different rTMS or TBS protocols that have been applied in researches investigating MDD patients with certain psychiatric comorbidities and discusses biomarkers that may be used to predict rTMS treatment response. Furthermore, we highlight the need for the validation of neuroimaging and electrophysiological biomarkers associated with rTMS treatment responses. Finally, we discuss on which directions future efforts should focus for developing the personalization of the treatment of depression with rTMS or iTBS.

OBJECTIVETo evaluate efficacy and advantages of the Traditional Chinese Medicine (TCM) synthetic rehabilitation therapy in the treatment of wrist dysfunction after distal radius fractures.

METHODSFrom May 2014 to October 2015, 72 patients with distal radius fracture meeting standards were treated using central randomization system for clinical research. All the patients were divided into two groups: 36 patients in test group and 36 in control group. Sixty-nine cases were finished treatment and followed up in the end. The test group fell off 1 case, and the control group fell off 2 cases. The test group was given TCM synthetic rehabilitation (manipulative therapy, joint mobilization, soaking-washing with Chinese medicinal herbs, functional exercise), and the control group was given functional exercise as well as soaking-washing with Chinese medicinal herbs, 3 weeks for both. Five evaluation standards were used in this research, which were grip strength, patient-rated wrist evaluation (PRWE), Gartland and Werley wrist score, self-rating anxiety scale(SAS) and the overall curative effect evaluation. Before treatment(baseline), after 3 weeks of treatment and 3 months after fracture were the three points in time when collected the data.

RESULTSAfter 3 weeks of treatment and 3 months after fracture, the test group had a significantly better results than those of control group in the PRWE, G-W wrist score and the overall curative effect evaluation(<0.05). In terms of grip strength recovery, after 3 weeks of treatment, the intergroup difference between the test group and the control group were statistically significant relative to the baseline regarding grip strength of ipsilateral wrist by group t-test(<0.05). However, the test group and the control group had no statistically significant relative to the baseline at 3 months after fracture in grip strength(<0.05). For the anxiety of patients, compared with the test group and control group at before and after rehabilitation treatment, the anxiety of both test group and control group cases was eased(<0.05). However, The degree of anxiety relief in test group and control group cases had no difference(>0.05).

CONCLUSIONSThe TCM synthetic rehabilitation therapy has better curative effects on the treatment of functional disability of wrist joints after distal radius fractures than the general therapy of soaking-washing with Chinese medicinal herbs and functional exercise.

Subthalamic nucleus (STN) is the main target nucleus for deep brain stimulation (DBS) treatment in patients with Parkinson disease.To implant the electrode on the sensorimotor part of STN individually and accurately,the boundary of STN is required to be clarified clearly on the magnetic resonance imaging (MRI) without geometric distortion.At present,there are three categories of MRI sequences:spin echo sequence including T2-weighted imaging (T2WI),inversion recovery (IR),diffusion tensor imaging (DTI),and fractional anisotropy (FA);magnetization transfer technique including magnetic susceptibility weighted imaging (SWI) and T2-weighted magnitude imaging (T2 * WI);image reconstruction technique such as quantitative susceptibility mapping (QSM).It is found that QSM can provide optimal signal-noise ratio to identify the boundary of STN,T2 * technique comes second.T2WI has high geometric accuracy when the patients wear frame,which is appropriate for direct DBS implantation on STN with frame.

BACKGROUNDReactive oxygen species are thought to contribute to the development of renal damage. The P22phox subunit of nicotinamide adenine dinucleotide phosphate (NAPDH) oxidase, encoded by the cytochrome b245a polypeptide gene, CYBA, plays a key role in superoxide anion production. We investigated the association of CYBA rs7195830 polymorphism with estimated glomerular filtration rate (eGFR) and the role it plays in the pathogenesis of chronic kidney disease (CKD) in a Han Chinese sample.

METHODSThe Gaoyou study enrolled 4473 participants. Serum levels of creatinine were measured and eGFR was estimated using the Chronic Kidney Disease Epidemiology Collaboration equations. The CYBA polymorphisms were genotyped. Then we investigated the association between eGFR and the rs7195830 polymorphism in the recessive model.

RESULTSThe AA genotype of rs7195830 was associated with significantly lower values of eGFR compared with the GG and AG genotypes ((102.76 ± 17.07) ml×min(-1)×1.73 m(-2) vs. (105.08 ± 16.30) ml×min(-1)± 1.73 m(-2)). The association remained significant in the recessive model after adjusting for age, gender, body mass index, smoking, hypertension, diabetes mellitus, uric acid, triglyceride, low density lipoprotein cholesterol and high density lipoprotein cholesterol (β=1.666, P=0.031). The rs7195832 AA genotype was an independent risk factor for CKD: eGFR <60 ml×min(-1)×1.73 m(-2) (odds ratio=3.32; 95% CI=1.21-9.13).

CONCLUSIONThe AA genotype of rs7195830 is independently associated with lower estimated glomerular filtration rate and is significantly associated with CKD.
