Occlusion of the aneurysm was achieved by placing permanent clips on the VA proximal and distal to the aneurysm and the PICA next to the aneurysm sac without occluding the perforator. The postoperative course was uneventful with bypass patency. We believe this case demonstrates the surgical tenet of OA-PICA bypass for VA-PICA aneurysm.A persistent stapedial artery originates from the petrous segment of the internal carotid artery due to failure of the regression of the embryonic stapedial artery. During embryologic development, the stapedial artery supplies the middle meningeal artery through the ventral pharyngeal artery. The presence of a persistent stapedial artery can result in direct communication between the basilar and middle meningeal arteries. We present a cerebral angiogram image of an adult patient that shows a right-sided persistent stapedial artery with communication between the right middle meningeal and basilar arteries. It is important to recognize such rare anatomic variants during endovascular interventions to avoid catastrophic complications such as nontarget embolization of the posterior circulation.

Laser interstitial thermal therapy (LITT) is a minimally invasive alternative to anterior temporal lobectomy (ATL) for treatment of temporal lobe epilepsy. It has gained popularity as familiarity with technique increases and outcomes are better characterized. There has been no direct cost comparison between the 2 techniques in literature to date. The current study directly compares hospital costs associated with LITT with those of ATL patients and analyzes the factors potentially responsible for those costs.

Patients who underwent ATL (27) and LITT (15) were retrospectively reviewed for total hospital costs along with demographic, surgical, and postoperative factors potentially affecting cost. T-tests were used to compare costs and independent linear regressions, and hierarchical regressions were used to examine predictors of cost for each procedure.

Mean hospital costs of admission for single-trajectory LITT ($104,929.88) were significantly less than for ATL ($134,980.04) (P= 0.001). In addition, length of stay, anesthesia costs, operative room costs, and postoperative hospitalization costs were all significantly lower in LITT.

Given the minimally invasive nature of LITT, it is associated with shorter length of stay and lower hospital costs than ATL in the first head-to-head comparison of procedural costs in literature to date. Long-term efficacy as it relates to these costs associated with LITT and ATL should be further investigated to better characterize the utility of LITT in temporal lobe epilepsy patients.

To our knowledge, only 2 cases have been reported previously and are supplied by a unilateral lateral sacral artery (LSA). Here, we report a rare cauda equina AVM at the level of L5-S1, which is supplied by the bilateral LSAs. Given the multiple feeders and complex angioarchitecture, endovascular embolization was performed with Onyx (ev3) successfully. The postoperative course of the patient was uneventful, and symptoms gradually improved. The present case demonstrated the angioarchitecture of the bilateral arterial supplies and venous drainage of the cauda equina AVMs. Cauda equina AVM with bilateral arterial feeders is extremely rare. However, clinicians should be aware of the possibility of this condition and the importance of selective spinal angiography of bilateral LSAs.

The optimal management of intraventricular metastases remains debatable. The aim of this study is to define the safety and efficacy of Gamma-Knife radiosurgery in the treatment of intraventricular metastases.

This retrospective, single-center study involved patients that were treated with stereotactic radiosurgery (SRS) for intraventricular metastases. The study end points included SRS-related toxicity, local and distal intracranial tumor control, as well as the incidence of post-treatment hydrocephalus and leptomeningeal dissemination. Factors associated with radiologic and clinical outcomes were also analyzed.

The cohort included 17 consecutive patients who underwent stereotactic radiosurgery for treatment of 41 intracranial metastases, of which 23 were primary intraventricular (intraventricular metastasis). Median overall survival from primary tumor diagnosis and from SRS treatment were 28 and 5 months, respectively. With a median radiological follow-up of 3 (interquartile range 3) months, 7 patients (41.18%) experienced overall intracranial disease progression, whereas 7 (27.27%) intraventricular metastases progressed radiologically. Four (23.53%) and 3 (17.65%) patients developed hydrocephalus and leptomeningeal dissemination post-SRS, respectively. Four patients (23.53%) died due to intracranial disease progression.

SRS offers a reasonable chance of local tumor control for patients with intraventricular brain metastasis. However, the risk of hydrocephalus and leptomeningeal spread of disease is not inconsequential and merits close follow-up for patients with brain metastasis involving the ventricular system.

Aggression is common and challenging in psychiatric emergency departments (PED). However, the prevalence of aggression and its correlates in PED patients are not well documented. This study compared the prevalence of aggression between patients with acute schizophrenia and manic episodes.

In this cross-sectional study, patients at a psychiatric emergency department were assessed with measurements of aggression, psychotic and manic symptoms.

A total of 4,172 patients were included. The prevalence of aggression was 54.8% (95%CI=53.3%-65.2%) in the whole sample, with 48.0% (95%CI=45.8%-50.1%) in patients with an acute schizophrenia episode, and 61.8% (95%CI=59.8%-63.9%) in patients with a manic episode. Multiple logistic regression analysis revealed that, within the acute schizophrenia episode group, male gender (OR=1.47, P<0.01), involuntary admission (OR=3.61, P<0.01) and more severe manic symptoms (OR=1.30, P<0.01) were significantly associated with aggression. Within the manic episode group, living in Beijing (OR=1.51, P<0.01), unemployment (OR=1.34, P=0.03), involuntary admission (OR=7.93, P<0.01), lower education (OR=0.95, P=0.01) and more severe psychotic symptoms (OR=1.05, P<0.01) were significantly associated with aggression.

In this study, aggression appeared to be more common among patients with a manic episode than those with an acute schizophrenia episode. Considering the significant risk of aggression on psychiatric emergency care, appropriate and effective management of aggression in this population group need to be developed.

We aimed to investigate the prescription pattern of pregabalin augmentation of antidepressants in major depressive disorder (MDD) and to explore variables associated with add-on pregabalin treatment.

1410 MDD patients participated in this naturalistic European multicenter study with retrospective assessment of treatment response. Analyses of covariance, chi-squared tests, and binary logistic regressions were accomplished to determine differences in socio-demographic and clinical characteristics between MDD patients with and without pregabalin augmentation.

Add-on pregabalin was established in 102 (7.23%) MDD patients. Compared to those without receiving pregabalin, pregabalin-treated patients were characterized by a significantly higher likelihood for older age (mean 54.74 ± 13.08 vs 49.93 ± 14.13 years), unemployment (78.43% vs 51.23%), melancholic features (83.33% vs 58.94%), inpatient treatment (72.55% vs 31.65%), previous psychiatric hospitalizations (13.52 ± 24.82 vs 4.96 ± 19.93 weeks), any somati comorbid anxiety symptoms could be determined.Efficient and convenient genetic manipulation of mycobacteria, important microorganisms in human healthcare and the pharmaceutical industry, is limited. In this study, using a model strain Mycolicibacterium neoaurum ATCC 25795, the classical bacterium for the production of valuable steroidal pharmaceuticals, a genome editing system employing CRISPR-Cas12a to achieve efficient and precise genetic manipulation has been developed. Targeted genome mutations could be easily achieved by the CRISPR-Cas12a system without exogenous donor templates, assisted by innate non-homologous end-joining (NHEJ). CRISPR-Cas12a enabled rapid one-step genomic DNA fragment deletions of 1 kb, 5 kb, 10 kb, 15 kb, 20 kb and 24 kb with efficiencies of 70 %, 30 %, 30 %, 20 %, 20 % and 10 %, respectively. Combined with the pNIL/pGOAL system, CRISPR-Cas12a successfully integrated the gene of interest into the targeted genomic site by single crossover and double crossovers with efficiencies of 100 % and 9 %, respectively, using a two-plasmid system. The robust CRISPR systems developed demonstrated strong potential for precise genome editing in M. neoaurum, including targeted deletion of DNA sequences of various lengths and integration of targeted genes into desired sites in the genome.Iris involvement by acute lymphoblastic leukemia is a very rare primary leukemic infiltration. Blurred vision, conjunctival injection, anterior chamber reaction, pseudohypopyon, thickening of the iris stroma, change in iris shape and color are common clinical signs in leukemic iris infiltration. There is no optimal treatment. Epertinib in vivo Radiotherapy, systemic chemotherapy (high-dose of methotrexate and/or high-dose cytarabine), topical and systemic corticosteroids have been reported as treatment modalities. Herein we present anterior segment optical coherence tomography findings in a 21-years-old, male, diffuse B-cell Acute Lymphoblastic Leukemia (ALL) patient who has a leukemic iris infiltration in his left eye that was successfully treated with intravitreal methotrexate.Semiconducting polymer (SP) is a promising photothermal agent in the antitumor application, but the co-delivery of the second near-infrared window (NIR-II)-based SPs with chemotherapeutic drug (e.g., doxorubicin (DOX)) remains a challenge. Here, SPs were firstly improved via backbone and alkyl side-chain engineering, and afterward, SPs and pH-sensitive prodrug copolymer self-assembled into a nanoparticle for a photoacoustic (PA)-imaging guided combination of photothermal therapy and chemotherapy. SP-encapsulated nanoparticles exhibited a high photothermal conversion efficiency of 45% at a relatively low power level of NIR irradiation (0.3 W/cm2 for 5 min). DOX was rapidly released in response to the acidic lysosomal environment. PA and fluorescence imaging confirmed that the photothermal therapy effectively drove DOX penetration inside tumor tissue, and it resulted in the killing of the surviving tumor cells from hyperthermia. The synergistic effect of SP-based photothermal therapy and DOX-induced chemotherapy was verified in vivo.
