Abstract
Glass dosimeters are very useful and convenient detection elements in radiation dosimetry. In this study, this glass dosimeter was applied to a BNCT treatment field. Boron Neutron Capture Therapy (BNCT) is a next-generation radiation therapy that can selectively kill only cancer cells. In the BNCT treatment field, both neutrons and secondary gamma-rays are generated. In other words, it is a mixed radiation field of neutrons and gamma-rays. We thus proposed a novel method to measure only gamma-ray dose in the mixed field using two RPLGD (Radiophoto-luminescence Glass Dosimeter) and two sensitivity control filters in order to control the dose response of the filtered RPLGD to be proportional to the air kerma coefficients, even if the gamma-ray energy spectrum is unknown. As the filter material iron was selected, and it was finally confirmed that reproduction of the air kerma coefficients was excellent within an error of 5.3% in the entire energy range up to 10 MeV. In order to validate this method, irradiation experiments were carried out using standard gamma-ray sources. As the result, the measured doses were in acceptably good agreement with the theoretical calculation results by PHITS. In the irradiation experiment with a volume source in a nuclear fuel storage room, the measured dose rates showed larger compared with survey meter values. In conclusion, the results of the standard sources showed the feasibility of this method, however for the volume source the dependence of the gamma-ray incident angle on the dosimeter was found to be not neglected. In the next step, it will be necessary to design a thinner filter in order to suppress the effect of the incident angle.

Abstract
We performed a literature search to identify the details of patients with right ventricular outflow tract obstruction caused by an aneurysm of the ventricular membranous septum in a perimembranous ventricular septal defect. Thirty-one cases with a median age of 29 years (range, 1-69 years) were studied. A right ventricle-pulmonary artery systolic pressure gradient ranged from 35 to 107 mm Hg (mean 69 mm Hg). An interventricular shunt was absent in eight patients: two children and six adults. It is necessary to monitor the size of an aneurysm of the ventricular membranous septum, whether or not an interventricular shunt is present.

Abstract
Gastrointestinal stromal tumors (GISTs) are mesenchymal neoplasms with variable behavior characterized by differentiation toward the interstitial cells of Cajal occurring anywhere in the gastrointestinal stromal tract. Frequently, GISTs have fibrous stroma within tumor cell proliferation areas, which is unlike other types of malignant tumors. If this desmoplasia is active, there is a possibility that some sort of transmitter exists between GIST cells and cells related to fibrosis in the tumor cell proliferation areas. Transforming growth factor (TGF)-β isoforms, particularly TGF-β1, are critical for fibrosis pathogenesis. TGF-β1 regulation of myofibroblasts and fibroblasts during fibrosis is well described. The induced fibroblast activation resulting in myofibroblast differentiation has been reported as an important source of collagen, glycoproteins, proteoglycans, and matrix metallopeptidases in wound healing and fibrosis. However, there are a few reports on the relationship between TGF-β1 and GISTs. This study aims to clarify TGF-β1 expression in 30 gastric GISTs using immunohistochemistry and reverse transcription polymerase chain reaction (RT-PCR). For comparison, we also enrolled 30 samples of gastric tubular adenocarcinoma (GTAC). We confirmed TGF-β1 expression (H-score ≥50 points) in 57% of GIST and 13% of GTAC samples, a significant difference between the 2 tumor types ( P =0.001). We examined the TGF-β1 mRNA expression of 3 representative GIST samples, each having their respective immunostained areas detected by RT-PCR. Finding TGF-β1 expression may indicate that this cytokine plays a part in the formation of desmoplasia within GIST cell proliferative areas.

Abstract
The influences of shared orthography, semantics, and phonology on bilingual cognate processing have been investigated extensively. However, mixed results have been found regarding the effects of phonological similarity on L2 cognate processing. In addition, most existing studies examining the influence of phonological similarity on cognate processing have been conducted on alphabetic scripts, in which phonology and orthography are always associated. Hence, in this study, we recruited Cantonese-Japanese bilinguals who used two logographic scripts, traditional Chinese and Japanese Kanji, to examine the influence of phonological similarity on L2 cognate lexical decision. Importantly, these scripts allow the manipulation of phonological similarity using identical characters across both languages. In addition, we examined how word frequency and L2 proficiency modulate cognate processing. Results showed that although word frequency and L2 proficiency played important roles in cognate processing, there was minimal overall influence of phonological similarity on cognate lexical decision. The latter finding suggests that theoretical models of bilingual word recognition may need to be refined to enhance our understanding of cognate processing regarding the role of phonology among diverse bilingual populations.

Abstract
BACKGROUND Systemic therapy for cancer treatment has improved, and therapeutic options for intracranial lesions are increasing. Combinations of treatment modalities are required in certain difficult cases. Gamma Knife radiosurgery (GKS) is effective for the treatment of brain metastases, especially for lesions that are inoperable because of their anatomical or functional location. OBSERVATIONS The authors report a case of brain metastases in anaplastic lymphoma kinase (ALK)-positive lung adenocarcinoma initially treated with GKS followed by the combination of repeat GKS and ALK tyrosine kinase inhibitors (ALK-TKIs) for tumor recurrence. During the clinical course, acquired resistance to ALK-TKIs due to the long exposure period was suspected. After a great deal of thought and discussion with the oncologist responsible for the treatment of the pulmonary lesions, the authors successfully controlled the lesion for the next 17 months by salvage pemetrexed administration. LESSONS This is the first report on the effectiveness of pemetrexed for recurrent brain metastasis from ALK-positive lung adenocarcinoma resistant to both radiosurgery and ALK inhibitors. Salvage pemetrexed showed a favorable therapeutic effect in this specific case.

Abstract
OBJECTIVE To investigate the diagnostic performance of a calcium-removal image reconstruction algorithm with photon-counting detector-computed tomography (PCD-CT), a technology that hides only the calcified plaque from the spectral data in coronary calcified lesions. METHODS This retrospective study included 17 patients who underwent PCD-coronary CT angiography (CCTA) with at least one significant coronary stenosis (≥50 %) with calcified plaque by CCTA and invasive coronary angiography (ICA) performed within 60 days of CCTA. A total of 162 segments with calcified plaque were evaluated for subjective image quality using a 4-point scale. Their calcium-removal images were reconstructed from conventional images, and both images were compared with ICA images as the reference standard. The contrast-to noise ratios for both images were calculated. RESULTS Conventional and calcium-removal images had a subjective image quality of 2.7 ± 0.5 and 3.2 ± 0.9, respectively (p < 0.001). The percentage of segments with a non-diagnostic image quality was 32.7 % for conventional images and 28.3 % for calcium-removal images (p < 0.001). The segment-based diagnostic accuracy revealed an area under the receiver operating characteristic curve of 0.87 for calcium-removal images and 0.79 for conventional images (p = 0.006). Regarding accuracy, the specificity and positive predictive value of calcium-removal images were significantly improved compared with those of conventional images (80.5 % vs. 69.5 %, p = 0.002 and 64.1 % vs. 52.0 %, p < 0.001, respectively). The objective image quality of the mean contrast-to-noise ratio did not differ between the images (13.9 ± 3.6 vs 13.3 ± 3.4, p = 0.356) CONCLUSIONS: Calcium-removal images with PCD-CT can potentially be used to evaluate diagnostic performance for calcified coronary artery lesions.

Abstract
This article detailly describes the subtemporal-transtentorial STA-SCA bypass technique. Through temporal base drilling, copious cerebrospinal fluid evacuation before retraction, and sufficient retraction of the temporal lobe preserving the veins of the temporal base would be primodial to obtain an appropriate surgical field. Refrection of the tentrial free edge and identification of recipient SCA posterior to the entry point of the trochlear nerve into the cavernous sinus is a micro-anatomical key. Bilateral bayonet-type needle holders and forceps should be used not to shadow the surgical corridor with one's hands.

Abstract
Pulmonary neuroendocrine tumors are rare, accounting for approximately 1% to 2% of lung cancers. Atypical carcinoids account for approximately 10% of pulmonary neuroendocrine tumors and are categorized as moderately malignant. Treatment options for advanced-stage atypical carcinoids include everolimus, cytotoxic anticancer agents, and peptide receptor radionuclide therapy. In this report, we present the first case of KRAS G12C mutation-positive atypical carcinoid that was successfully treated with sotorasib. Therapeutically important mutations observed in non-small cell lung cancer are seldom found in atypical carcinoid tumors. Nonetheless, it is worthwhile to search for genetic mutations in atypical carcinoid tumors, considering the potential for molecular targeted therapy to be effective in their treatment as well.

Abstract
We examined the developmental trajectories and cognitive predictors of first language Chinese reading, second language English reading, and mathematics skills in Hong Kong children in Grades 1-5. We used longitudinal data of 1,000 children (Mage = 7.59 years) assessed on phonological awareness, rapid naming, and morphological awareness in Grade 1 and Chinese word reading, English word reading, and arithmetic calculations in Grades 1-5. Results revealed a decelerating growth pattern for word reading in Chinese and English and a linear growth pattern for arithmetic calculations. Rapid naming and morphological awareness predicted the initial status of all academic skills. The findings suggest that although these academic skills share initial cognitive processes, they follow remarkably different developmental trajectories.

Abstract
Spontaneous regression of an arteriovenous malformation (AVM) is a rare condition observed in 0.3%-1.3% of patients with AVMs and is most likely caused by hemorrhagic events. The regression of an unruptured AVM is rarer than that of a ruptured AVM. Moreover, due to its low frequency of occurrence, the etiology and natural course of spontaneous regression of an AVM is still unclear. This is the first report presenting a case of a spontaneous regression of an unruptured AVM caused by a gradual drainer vein thrombosis that was suspected to result from hypercoagulability due to protein S deficiency.

Abstract
Nuclear morphology of carcinoma cells is critical for the pathological diagnosis of papillary thyroid carcinoma (PTC). However, three-dimensional architecture of PTC nuclei is still elusive. In this study, we analyzed the three-dimensional ultrastructure of PTC nuclei using serial block-face scanning electron microscopy which takes advantage of the high-throughput acquisition of serial electron microscopic images and three-dimensional reconstruction of subcellular structures. En bloc-stained and resin-embedded specimens were prepared from surgically removed PTCs and normal thyroid tissues. We acquired two-dimensional images from serial block-face scanning electron microscopy and reconstructed three-dimensional nuclear structures. Quantitative comparisons showed that the nuclei of carcinoma cells were larger and more complex than those of normal follicular cells. The three-dimensional reconstruction of carcinoma nuclei divided intranuclear cytoplasmic inclusions into "open intranuclear cytoplasmic inclusions" connecting to cytoplasm outside the nucleus and "closed intranuclear cytoplasmic inclusions" without that connection. Cytoplasm with abundant organelles was observed in open inclusions, but closed inclusions contained fewer organelles with or without degeneration. Granules with a dense core were only observed in closed inclusions. Our observations suggested that open inclusions originate from nuclear invaginations, and disconnection from cytoplasm leads to closed inclusions.

Abstract
PURPOSE To compare treatment results between fractionated gamma knife radiosurgery (f-GKRS) and staged gamma knife radiosurgery (s-GKRS) for mid-to-large brain metastases (BMs). METHODS We retrospectively analyzed data of patients with medium (4-10 mL) to large (> 10 mL) BMs who underwent s-GKRS or f-GKRS between March 2008 and September 2022. Patients were treated with (i) s-GKRS before May 2018 and (ii) f-GKRS after May 2018. Patients who underwent follow-up magnetic resonance imaging at least once were enrolled. Case-matched studies were conducted by applying propensity score matching to minimize treatment selection bias and potential confounding. Local control (LC) was set as the primary endpoint and overall survival (OS) as the secondary endpoint. RESULTS This study included 129 patients with 136 lesions and 70 patients with 78 lesions who underwent s-GKRS and f-GKRS, respectively. Overall, 124 lesions (62 lesions in each group) were selected in the case-matched group. No differences were observed in the 6-month and 1-year cumulative incidences of LC failure between the s-GKRS and f-GKRS groups (15.6% vs. 15.9% at 6 months and 25.6% vs. 25.6% at 1 year; p = 0.617). One-year OS rates were 62.6% (95% confidence interval [CI]: 45.4-75.7%) and 73.9% (95% CI: 58.8-84.2%) in the s-GKRS and f-GKRS groups, respectively. The post-GKRS median survival time was shorter in the s-GKRS group than in the f-GKRS group (17 vs. 36 months), without significance (p = 0.202). CONCLUSIONS This is the first study to compare f-GKRS and s-GKRS in large BMs. Fractionation is as effective as staged GKRS for treating mid-to-large BMs.

Abstract
Fever in hospitalized patients requires timely identification of the underlying cause for appropriate treatment. While laboratory tests and imaging studies are valuable, the significance of physical examination should not be overlooked. We present a case of peripheral line-associated bloodstream infection that was readily diagnosed through physical examination during an infectious disease consultation for fever of unknown origin. It is important for busy physicians to prioritize physical examinations to prevent diagnostic errors. Prompt and focused physical examinations contribute to improved patient outcomes and the prevention of healthcare-associated infections.

Abstract
Background As the overall survival in non-small-cell lung cancer has increased, safer, long-term treatments for brain metastases are increasingly needed. This study aimed to analyze the outcomes of fractionated and single-fraction gamma knife radiosurgery for brain metastases from non-small-cell lung cancer, focusing on driver alteration status. Methodology Patients who underwent gamma knife radiosurgery as their first local treatment for brain metastases from non-small-cell lung cancer between May 2018 and December 2021 at our institution were retrospectively enrolled. Results Among the 98 patients (287 lesions), 45 (130 lesions) harbored driver alterations, including epidermal growth factor receptor mutations in 35 patients and anaplastic lymphoma kinase or ROS1 rearrangement in 10 patients. Overall, 64 and 34 patients underwent single-fraction and fractionated radiosurgery (3-15 fractions), respectively. Large tumor size was a risk factor for recurrence, while fractionated radiosurgery (subdistribution hazard ratio (sHR) = 16.47; confidence interval (CI) = 3.58-75.77; p < 0.001) and small tumor size (sHR = 1.15; CI = 1.04-1.28; p = 0.008) independently protected against radiation necrosis. In the case-matched analyses, the cumulative radiation necrosis rates were significantly lower in the fractionated group than in the single-fraction group among all lesions (p = 0.017) and among those with driver alterations (p = 0.046), whereas no significant difference was confirmed among wild-type lesions (p = 0.382). Conclusions Fractionated gamma knife radiosurgery may be an alternative therapeutic approach for reducing the risk of radiation necrosis, particularly for patients with driver alterations, even when the tumors are small. Further research is necessary to determine the optimal indications for fractionated gamma knife radiosurgery and fractionation methods.

Abstract
Boron Neutron Capture Therapy (BNCT) is a cell-selective radiotherapy using a neutron capture reaction of 10B. In recent years, Accelerator Based Neutron Sources (ABNS) are under development instead of nuclear reactors for the next-generation neutron irradiation system for BNCT. However, ABNS as well as nuclear reactor usually generates unavoidable secondary gamma-rays by neutron-nuclear reactions such as capture reaction. In this research, we aimed to develop a separate measurement method of only gamma-rays in a mixed field of neutrons and gamma-rays using a fluorescent glass dosimeter (RPLGD), because most dosimeters have sensitivity to both radiation types. For this purpose, we proposed a lead filter method using two RPLGDs and lead filters. However, this method has a problem that the sensitivity to low energy gamma-rays (∼100 keV) is very small. In order to improve the sensitivity to low energy gamma-rays, we devised a method using a specially shaped lead filter. From theoretical calculations, we have shown that it was possible to estimate the air dose rate of the field where the gamma-ray energy spectrum shape was known for energies up to 10 MeV. In addition, we produced the specially shaped lead filter and experimentally confirmed the validity of the lead filter method using several gamma-ray standard sources and by measurements in a nuclear fuel storage room.

Abstract
We examined the reciprocal associations between home literacy environment (HLE) and children's early reading skills in syllabic Hiragana and morphographic Kanji in a sample of Japanese parent-child dyads. Eighty-three children were followed from kindergarten to Grade 3 and tested on Hiragana reading accuracy in kindergarten, Hiragana word reading fluency in kindergarten and Grade 1, and Kanji reading accuracy in Grade 1 to Grade 3. Their parents answered a questionnaire about HLE [parent teaching (PT) in Hiragana and Kanji, shared book reading (SBR), and access to literacy resources (ALR)], parents' needs for early literacy support by teachers, parents' expectations for children's reading skills, parents' worry about children's homework, and mother's education level. Results showed first that ALR, but not PT and SBR, was associated with reading skills in Hiragana and Kanji. Second, whereas Hiragana reading in kindergarten was not associated with PT in Hiragana in kindergarten, it negatively predicted PT in Hiragana in Grade 1. However, Kanji reading accuracy was not associated with PT in Kanji across Grades 1 to 3. Third, parents' worry was negatively associated with children's reading performance across Grades 1 to 3 but positively associated with PT in Hiragana and Kanji. Finally, while parents' expectations were positively associated with children's reading performance across Grades 1 to 3, they were negatively associated with PT in Hiragana and Kanji in Grades 1 and 2. These results suggest that Japanese parents may be sensitive to both their children's reading performance and social expectations for school achievement and adjust their involvement accordingly during the transition period from kindergarten to early primary grades. ALR may be associated with early reading development in both Hiragana and Kanji.

Abstract
The accuracy of percutaneous pedicle screw (PSS) placement in the lateral decubitus position has seldom been reported. This study aimed to retrospectively compare the accuracy of PPS placement with 3-dimensional (3D) fluoroscopy-based navigation in 2 cohorts of patients who underwent surgery in the lateral decubitus or prone positions at our single institute. A total of 265 consecutive patients underwent spinal surgery with PPS from T1 (thoracic 1) to S (sacrum) under the 3D fluoroscopy-based navigation system at our institute. Patients were divided into 2 groups based on their intraoperative patient positioning: lateral decubitus (Group L) or prone (Group P). A total of 1816 PPSs were placed from T1 to S, and 76 (4.18%) PPSs were assessed as deviated PPS. Twenty-one of 453 (4.64%) PPSs in Group L deviation and 55 of 1363 (4.04%) PPSs in Group P had deviated PPS, but with not significant difference (P = .580). In Group L, although the PPS deviation rate was not significantly different between the upside and downside PPS, the downside PPS significantly deviated toward the lateral side compared with the upside PPS. The safety and efficacy of PPS insertion in the lateral decubitus position were similar to those in the conventional prone position.

Abstract
BACKGROUND Adult patients with moyamoya disease (MMD) may present with mild cognitive dysfunction, even those without evidence of conspicuous brain parenchymal damage. This cognitive dysfunction might be caused by local frontal lobe ischemia. OBJECTIVE To explore the relationship between frontal lobe hemodynamic insufficiency and cognitive dysfunction in patients with MMD. METHODS Thirty adult patients with MMD without conspicuous brain parenchymal damage were retrospectively examined. Patients with MMD with frontal lobe intracerebral steal phenomenon on single photon emission computed tomography were defined as group S (n = 13) and those without it were defined as group P (n = 17). A comparative group comprising patients with unruptured intracranial aneurysm was defined as group C (n = 30). The results of various cognitive and intelligence tests and a composite cognitive score were compared between groups. RESULTS The digit span test forward version ( P = .041), frontal assessment battery ( P = .022), and composite cognitive score ( P = .015) z-scores were significantly lower in group S than group C. Adjusting for sex and age, patients in group S had a significantly lower composite cognitive score compared with those in group C in multiple regression analysis ( P = .037). Executive dysfunction and working memory dysfunction may be involved in the cognitive decline observed in group S. CONCLUSION Mild cognitive dysfunction in MMD was associated with frontal lobe hemodynamic insufficiency. Future studies should examine whether revascularization can improve cerebral hypoperfusion and neurocognitive function in these patients.

Abstract
We examined if North (n = 123) and South Korean (n = 123) children in Grades 3 to 8 studying in South Korea differ in their reading, vocabulary, and literacy-related cognitive skills, and whether language and literacy-related skills contribute to reading outcomes differently among North and South Korean children. The results showed that South Korean students performed better in syllable deletion, RAN-Letters, vocabulary, decoding fluency, and reading comprehension after controlling for age and SES. No differences were observed in phonological awareness, RAN-Digits, and visual processing tasks. A multigroup path analysis showed that phonological awareness and vocabulary were more strongly associated with decoding fluency for the South than the North Korean students, whereas the opposite was true for visual processing. The results suggest that South Korean vocabulary knowledge may be a significant factor in addressing the academic difficulties facing North Korean children in South Korean schools and that it is important to consider linguistic characteristics when examining the variations in reading skills and vocabulary knowledge of North Korean students in South Korean schools. These findings have implications for North Korean children's literacy instruction in South Korean schools.

Abstract
Background Kluyvera intermedia is a bacterium indigenous to humans. But Kluyvera intermedia bacteremia has been not reported thus far. We report a case of Kluyvera intermedia bacteremia with septic shock due to left obstructive pyelonephritis as a result of urolithiasis. Case presentation A 66-year-old woman with septic shock due to left obstructive pyelonephritis was transferred to our hospital. Tazobactam/Piperacillin 4.5 g was administered every 8 h for 5 days. The patient's condition improved, and she was transferred back to the previous hospital. Kluyvera intermedia was obtained by blood cultures. The patient was successfully treated with a two-week course of antibiotics. Conclusions We describe the first case of bacteremia with septic shock caused by Kluyvera intermedia. Kluyvera intermedia can be a causative pathogen of septic shock. Since this bacterium has not been reported in the past, we expect further reports and the accumulation of cases in the future.

Abstract
Background Acute carotid stent thrombosis (ACST) is a rare but devastating complication for carotid artery stenting (CAS). That requires early diagnosis and immediate treatment. Although administration of drugs or endovascular treatment is the most widely used approach for patients with ACST, there is no consensus on the standard treatment of this disease. Case Description The present study reports on an 80-year-old female patient with the right internal carotid artery stenosis (ICS) that had been followed up by ultrasonography for 8 years. Although the optimal medical treatment was followed, the patient's right ICS worsened, and the patient was subsequently hospitalized for CAS. On the 12th day after CAS, left paralysis and dysarthria were observed. Head magnetic resonance imaging (MRI) showed acute obstruction of the stent and scattered cerebral infarction in the right cerebral hemisphere caused possibly by the discontinuation of temporary antiplatelet drug therapy as a means to prepare for embolectomy of the femoral artery. Stent removal and carotid endarterectomy (CEA) were selected as the appropriate treatment approach. CEA was performed with the precaution of stent removal and distal embolism, and complete recanalization was obtained. Postoperative head MRI showed no new findings of cerebral infarction, and the patients remained symptom-free after 6 months of postoperative follow-up. Conclusion Stent removal with CEA could be an appropriate curative option in some cases with ACST except in patients at high risk of CEA and in the chronic phase after CAS.

Abstract
BACKGROUND Quadricuspid pulmonary valve (QPV) is a rare congenital anomaly. Simple QPV had been mainly diagnosed at the time of autopsy before 2000, and the frequency rates of QPV are approximately 0.02%-0.41%. QPV was initially diagnosed using transthoracic echocardiography (TTE) after 2000 and with contrast computed tomography (CT) or cardiac magnetic resonance imaging (CMR) after 2009. Obtaining the cross-sectional view of the pulmonary valve using TTE is difficult. We aimed to review the papers regarding the incidence, embryology, diagnosis, associated congenital heart anomalies, and prognosis in patients with QPV, and furthermore to compare with those in patients with quadricuspid aortic valve (QAV). CASE PRESENTATION We diagnosed QPV with mild stenosis in a 12-month-old infant. With a slight angulation of the transducer superiorly from the left high parasternal short-axis view, a short-axis view of QPV was obtained. RESULTS In QPV cases diagnosed at autopsy, Hurwitz's type-b with three equal cusps and one smaller cusp is dominant, whereas Hurwitz's type-a with four equal cusps is dominant in clinically diagnosed cases. Congenital heart anomaly and valvular stenosis are more frequent in patients with QPV than in patients with QAV. Coronary artery anomalies and infectious endocarditis are more frequent in patients with QAV than in patients with QPV. The incidence of PR is more common in type-a QPV than in type-b QPV. There is no difference between type-a QAV and type-b QAV with respect to the incidence of aortic regurgitation (AR). It is assumed that QPV is a risk factor for a Ross operation. However, QPVs have been used as autografts in certain patients. CONCLUSION Between QPV and QAV, various differences were found in frequency rates, diagnostic methods, valve morphology, valve function, associated congenital heart diseases, and frequencies of infectious endocarditis.

Abstract
OBJECTIVE Antiangiogenic vascular endothelial growth factor receptor tyrosine kinase inhibitors play an essential role in systemic therapy for renal cell carcinoma. Given the anti-edematous effect of bevacizumab, an antiangiogenic antibody targeting vascular endothelial growth factor, vascular endothelial growth factor receptor tyrosine kinase inhibitors should exert therapeutic effects on radiation-induced brain injury after stereotactic radiosurgery. This preliminary study aimed to investigate the therapeutic effect of vascular endothelial growth factor receptor tyrosine kinase inhibitor against radiation-induced brain injury. METHODS Magnetic resonance images for six patients treated with vascular endothelial growth factor receptor tyrosine kinase inhibitors who were diagnosed with radiation-induced brain injury following gamma knife radiosurgery were retrospectively reviewed. RESULTS The median brain edema volume and tumour mass volume in the pre-tyrosine kinase inhibitor period were 57.6 mL (range: 39.4-188.2) and 3.2 mL (range: 1.0-4.6), respectively. Axitinib, pazopanib (followed by cabozantinib) and sunitinib were administered in four, one and one cases, respectively. The median brain edema volume and tumour mass volume in the post-tyrosine kinase inhibitor period were 4.8 mL (range: 1.5-27.8) and 1.6 mL (range: 0.4-3.6), respectively. The median rates of reduction in brain edema volume and tumour mass volume were 90.8% (range: 51.9-97.6%) and 57.2% (range: 20.0-68.6%), respectively. The post-tyrosine kinase inhibitor values for brain edema volume (P = 0.027) and tumour mass volume (P = 0.008) were significantly lower than the pre-tyrosine kinase inhibitor values. Changes in volume were correlated with tyrosine kinase inhibitor use. CONCLUSION This study is the first to demonstrate the therapeutic effects of vascular endothelial growth factor receptor tyrosine kinase inhibitors on radiation-induced brain injury in patients with brain metastases from renal cell carcinoma treated via gamma knife radiosurgery.

Abstract
Background Trigeminal neuralgia (TN) due to compression from the dolichoectatic vertebrobasilar artery (DVBA) is extremely rare and difficult to treat due to its morphological characteristics. We report two cases of good transposition of DVBA and postoperative course obtained using the anterior petrosal approach and a new vasoculopexy method. Methods We describe two cases of microvascular decompression (MVD) for refractory TN associated with DVBA. In both cases, MVD was performed through the anterior petrosal approach. The DVBA was decompressed using a GORE-TEX sling and WECK clip in an inferomedial direction. Results Complete pain relief without new neurological deterioration was achieved immediately in both patients. Conclusion We experienced a rare condition of TN due to exclusion by the DVBA. The anterior transpetrosal approach was extremely effective in this case. This approach secured the surgical field, allowed transposition of the DVBA, and caused no perioperative complications.

Germinoma of the primary midbrain is particularly rare, and its clinical features, treatment strategies, and long-term prognosis remain uncertain. Case Description A 39-year-old man who had been diagnosed with midbrain germinoma by open biopsy through the occipital transtentorial approach had undergone chemoradiotherapy and achieved 5 years with no recurrence. Conclusion Germinomas should be considered as a differential diagnosis for adolescents and young adult men with mesencephalic tumors, and reliable sampling followed by chemoradiotherapy must be performed.

Abstract
We examined whether different parent- and teacher-related factors had an effect on at-risk children's reading development during the first six months of the Covid-19 pandemic. Seventy Grade 1 English-speaking Canadian children (28 females, 42 males; M age = 6.60, SD = 0.46) who were at-risk for reading difficulties were administered word and pseudoword reading, nonverbal IQ, and phonological awareness tasks before the school closures (February 2020; Time 1). Reading tasks were administered again when they returned to school in September 2020 (Time 2). In April-May 2020, their parents (n = 70) and teachers (n = 40) filled out a questionnaire on the home literacy environment and the frequency of teaching reading and providing reading materials, respectively. Results of multilevel regression analyses showed that children's reading enjoyment and home learning activities predicted both word and pseudoword reading at Time 2. Differentiation of instruction for struggling readers also predicted children's pseudoword reading at Time 2. These findings reinforce the important role of parents in their children's early reading development particularly when the typical agents of instruction (i.e., teachers) have less time and opportunities to interact with their students because of the pandemic.

Abstract
BACKGROUND The transsylvian approach is a versatile treatment method for aneurysms of the anterior circulatory system. Studies have shown that sylvian veins run in various patterns, suggesting the need for dissection between veins to obtain appropriate surgical corridor. In case of inadvertent sylvian vein injury, serious complications such as venous congestion may occur. METHOD We herein describe the "side-to-side anastomosis reconstruction technique" of the resected superficial sylvian vein. CONCLUSION This technique can be effective for the reconstruction of other cortical veins, and indocyanine green videoangiography was effective in determining the indications for venous reconstruction.

Abstract
Abstract
Objective Because of their anatomical features, treatment for paraclinoid aneurysms has remained to be challenging. Thus, the aim of this report is to prove the validity of our surgical method for unruptured paraclinoid aneurysms, together with surgical videos.
Study Design Between August 2017 and November 2019, we were able to perform surgical clipping for 11 patients with unruptured paraclinoid aneurysm using a completely unified method. This study investigated the effect of surgery on multiple measures, including visual impairment, brain contusion, temporalis muscle atrophy, and multiple neurocognitive functions.
Results Of the 67 unruptured aneurysms treated at our hospital, 17 were identified to be paraclinoid aneurysm, and 11 of them were treated by direct clipping using anterior clinoidectomy. Three were ophthalmic artery aneurysms, three were superior hypophyseal artery aneurysms, and five were anterior carotid wall aneurysms without branch projection. Only one patient had asymptomatic mild enlargement of the Marriott blind spots postoperatively. No brain contusion and temporalis muscle atrophy were observed in any cases. Only the Trail Making test (TMT) showed a significant worsening in the acute postoperative period: mean pre- and postoperative TMT scores were 59.1 ± 29.1 and 72.7 ± 37.3 for Part A (p = 0.018) and 80.5 ± 35.5 and 93.8 ± 39.9 for Part B (p = 0.030), respectively. However, it improved in the chronic phase.
Conclusion We can conclude that our surgical method is safe and can be considered an acceptable treatment. Although surgical stress can cause temporary executive dysfunction shortly after surgery, this decline is temporary.

Abstract
RATIONALE Nodular fasciitis (NF) can be misdiagnosed as a sarcoma because of its rapid growth and pathological features, such as nuclear atypia and mitoses. PATIENT CONCERNS We present a rare case of a 72-year-old Japanese man who developed NF with suspected postirradiation myxofibrosarcoma (MFS) after segmentectomy for left-sided osteoradionecrosis (ORN) of the mandible. DIAGNOSIS A mass appeared in the intraoral postoperative wound 1 year after left-sided mandibular segmentectomy and showed rapid growth, reaching a size of 50 mm within 2 months. Incisional biopsy revealed strongly Ki-67-positive spindle-shaped cells with large irregular nuclei and a diagnosis of postirradiation MFS. INTERVENTIONS The patient was diagnosed with oropharyngeal cancer (T4aN2bM0) and underwent surgical resection of primary oropharyngeal squamous cell carcinoma with selective neck dissection and reconstruction with a rectus abdominis musculocutaneous flap at the age of 57 years, followed by postoperative 66 Gy of radiotherapy combined with cisplatin administration. No recurrent or metastatic lesions of oropharyngeal squamous cell carcinoma have been detected for > 10 years. However, the ORN of the jaw worsened, and the patient underwent sequestrectomy 3 times on the right side of the mandible, followed by a left-sided segmentectomy at the age of 72 years. One year after segmentectomy, a 10-mm mass with soft-to-firm consistency appeared in the buccal mucosa of the wound and grew rapidly. An incisional biopsy revealed MFS. Complete resection under general anesthesia was immediately performed. OUTCOMES The histopathological diagnosis of the excised specimen was NF without any malignant findings. Two years after surgery, there was no evidence of recurrence or metastasis. LESSONS NF grows rapidly and has pathological features similar to sarcoma, making differential diagnosis difficult at the time of incisional biopsy. Further studies should be conducted to determine the clinical and pathological features of this tumor.

Abstract
Traumatic anterior cerebral artery (ACA) aneurysms are extremely rare. Traumatic anterior ACA aneurysms are thought to develop when the ACA at the pericallosal segment travel adjacent to immobile falx cerebri. As the majority of aneurysms are pseudoaneurysms, direct neck clipping is usually not possible, and it is often necessary to carry out direct or endovascular trapping in conjunction with proficient bypass techniques. The authors describe the first reported case of a traumatic ACA pseudoaneurysm resulting from avulsion of the falcine branch of an azygos ACA. In this case, the lacerated aneurysm wall was successfully sutured, without the need for a bypass. Neurosurgeons should be aware that avulsion of the falcine branch arising from the ACA can occur, and that this may cause a traumatic aneurysm on the distal ACA. Furthermore, direct suturing of a lacerated arterial wall should be considered a treatment option for this type of traumatic intracranial aneurysm.

Abstract
PURPOSE Fractionated stereotactic radiotherapy (FSRT) using gamma knife is useful for brain metastases. However, several uncertainties derived from fractionation pose issues for maintaining high-level accuracy. This study analyzed interfractional tumor change by performing radiological reassessment at the midterm of FSRT with ≥ 10 fractions, and the significance of replanning was evaluated. METHODS Data of FSRT using gamma knife with ≥ 10 fractions were retrospectively collected. Interfractional volume changes in MRI at the midterm of the irradiation period were analyzed. Radiological changes after FSRT and final outcomes were also investigated. RESULTS Overall, 114 lesions in 74 treatments from 66 patients were included, with previously irradiated lesions accounting for 46%. The median interval between planning and the interfractional MRI was 7 days. The interfractional change rates of tumor volume ranged from - 48 to + 72%. Significant interfractional enlargement was observed in 16 lesions (14%); evident regression was confirmed in 17 lesions (15%). Predictive factors for interfractional enlargement were small tumor and cystic lesion; high biologically effective dose was associated with regression. After FSRT, most lesions regressed within 6 months despite interfractional change type. The incidences of tumor control and radiation necrosis indicated no differences between interfractionally-regressed lesions and others. CONCLUSION This is the first study to evaluate interfractional tumor change in FSRT using gamma knife with ≥ 10 fractions, indicating significant volume changes in 29% of the lesions. These preliminary results suggest that interfractional reassessment of a treatment plan in FSRT with irradiation periods exceeding a week is necessary for more adaptive treatment.

Abstract
Takotsubo cardiomyopathy (TCM) causes QT interval prolongation, potentially leading to a fatal arrhythmia. We report the first case of TCM associated with licorice‐induced pseudoaldosteronism causing fatal arrhythmia in an older patient on polypharmacy including yokukansan (TJ‐54) and galantamine. Polypharmacy should be resolved to prevent unexpected adverse events in older patients.

Abstract
The superficial temporal artery-middle cerebral artery(STA-MCA)bypass technique is extremely important as the basis for both cerebral revascularization in chronic-stage ischemia and emergency surgical revascularization, including open surgical embolectomy. The sophisticated technique of microvascular bypass could also contribute to rescuing inadvertent vascular injuries, such as those occurring in difficult tumor surgery. Therefore, novice neurosurgeons should practice mastering the microvascular suturing technique.

Abstract
Abstract
Study question
Does the migration speed of nucleolar precursor bodies (NPBs) in male and female pronuclei (mPN and fPN) affect in vitro fertilization (IVF)-derived embryo ploidy status?
Summary answer
The NPB migration speed in mPN impacts the IVF-derived human embryo ploidy status and this indicator could be an attractive marker for noninvasive embryo selection.
What is known already
NPBs are not considered as simple nucleolar components transmitted from an oocyte to an embryo, and they could participate in genome remodeling during embryo development. NPBs are essential only shortly after fertilization, suggesting that they may actively participate in centromeric chromatin establishment. A previous study demonstrated that NPBs migrated faster in intracytoplasmic sperm injection-derived zygotes having the potential to develop into a blastocyst and eventually into a baby (Inoue et al., 2021). However, the relationship between NPB migration speed and IVF-derived embryo ploidy status is unclear.
Study design, size, duration
The relationship between the NPB migration speed and embryo ploidy status was retrospectively analyzed in patients with recurrent assisted reproductive technology failure (euploid n =18; aneuploid n =19; and total = 219 NPBs). Archived time-lapse videos (images were recorded every 5 min; Geri+) from incubation after IVF were retrieved after the patients were identified for the study, and the NPB migration speed was analyzed. The retrospective analyses were performed with the patient’s identities masked.
Participants/materials, setting, methods
mPN and fPN were identified by appearance location in a zygote (fPN appearance is just below the polar bodies). The mPN, fPN, and 2–3 NPBs/PN central coordinates were measured by Kinovea (motion capture software). Their central coordinates were confirmed/revised every image and were decided. The migration distance of NPBs between two sequential images was calculated as the standard of the central PN coordinates. Thereafter, the migration speed of NPBs was calculated.
Main results and the role of chance
Both NPB speeds were significantly faster in the euploid than in the aneuploid groups (mPN: 4.08±0.61 vs. 3.54±0.54 µm/h, P =0.003, power [1-β]: 0.999, fPN: 4.03±0.89 vs. 3.26±0.45 µm/h, P <0.003, 1-β: 0.987). The NPB speed in mPN was correlated with that in fPN (rs =0.523, P =0.001). The ploidy status was related to the NPB speeds in mPN and fPN (P <0.05) in univariate logistic analysis including male/female ages, ICM/TE grades, and 29 morphokinetic parameters. The factors associated with ploidy status were the NPB speed in mPN (odds ratio [OR], 10.2; 95% confidence interval [CI], 1.90–54.90; P =0.007) and female age (OR, 0.8; 95%CI, 0.64–0.98; P =0.03) in multivariate logistic analysis. The cutoff value for the NPB speeds in mPN and fPN were 3.65 μm/h (specificity, 73.7%; sensitivity, 77.8%; AUC, 0.78; 95%CI, 0.62–0.93) and 3.77 μm/h (specificity, 89.5%; sensitivity, 66.7%; AUC, 0.78; 95%CI, 0.62–0.94). When the zygotes were categorized by their cutoff values, the euploid rate in zygotes with NPB speeds greater than the cutoff value was significantly higher than that in zygotes with the speeds less than the cutoff value (mPN = 73.7% vs. 22.2% [P =0.003]; fPN = 85.7% vs. 26.1% [P <0.001]).
Limitations, reasons for caution
The NPB migration in the z-axis direction could not be analyzed. NPB tracking could not be performed when NPBs were large in number or drastically moved. Our findings should help in elucidating the relationship, although they did not completely explain the relationship between NPB migration and embryo development.
Wider implications of the findings
The migration speed of NPBs impacts human embryo ploidy status. NPB migration speed may add clinical value for embryo selection, which may be associated with live birth, and consequently, the time of the live birth could be shorter. The indicator could be an attractive marker for noninvasive embryo selection.

Abstract
PURPOSE The prognostic value of F-18 fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) taken immediately after completion of radiotherapy in lung cancer patients is not well known. The purpose of this study is to assess the prognostic value of PET/CT taken immediately after completion of radiotherapy in lung cancer patients. MATERIALS AND METHODS Patients with primary lung cancer planned to undergo concurrent chemoradiotherapy were enrolled. Patients underwent PET/CT scans at 3 time points: before radiotherapy, within 24hours of completing radiotherapy (im-PET/CT), and 2-9 months after radiotherapy (post-PET/CT). Maximum standardized uptake value (SUVmax) was obtained. A post-PET/CT-SUVmax cut-off of 2.5 was determined as radiotherapy success. RESULTS Nineteen patients were enrolled. im-PET/CT-SUVmax for patients in the high post-PET/CT-SUVmax group was significantly higher than that of the low group (P=0.004). Receiver operator curve analysis indicated that im-PET/CT-SUVmax of 4.35 was an optimal cut-off value to discriminate between the two groups. Multivariable analysis showed that a high im-PET/CT-SUVmax was significantly associated with a high post-PET/CT-SUVmax (P=0.003). CONCLUSION PET/CT-SUVmax taken immediately following radiotherapy was associated with that evaluated 2-9 months after radiotherapy.

Abstract
Direct revascularization surgery, such as superficial temporal artery (STA)-middle cerebral artery (MCA) bypass, is effective in preventing ischemia and hemorrhage for moyamoya disease. On the other hand, when ischemia of the anterior cerebral artery (ACA) region progresses after ipsilateral STA-MCA bypass, it is difficult to perform revascularization from the viewpoint of the donor artery. A 55-year-old woman with right hemiparesis was diagnosed with cerebral infarction due to moyamoya disease. Left STA-MCA bypass was performed with no postoperative complications, but memory impairment and decreased motivation were observed 2 months after the operation. Magnetic resonance imaging and angiography revealed new infarction in the bilateral ACA area and deterioration in the signal intensity of bilateral ACAs. Revascularization of the bilateral ACA regions was considered necessary, but the left STA was already used in the previous surgery. Therefore, STA-radial artery (RA)-A3 bypass using RA graft combined with right STA-MCA bypass was performed. STA-A3 bypass using an RA graft may be the optimal treatment for ischemia of the ACA region that progresses after STA-MCA bypass.

Abstract
Recombinant tissue-type plasminogen activator with/without endovascular regimen is sometimes not effective for the treatment of acute hemodynamic stroke. Emergent superficial temporal artery-middle cerebral artery (STA–MCA) bypass has been reportedly effective in patients with progressive hemodynamic stroke; however, the effectiveness of urgent STA–MCA bypass for acute internal carotid artery (ICA) stenosis/occlusion with concomitant contralateral chronic ICA stenosis/occlusion, that is considered the worst hemodynamic situations, is unclear. Two cases of acute left ICA stenosis with concomitant right chronic ICA occlusion wherein both developed hemodynamic infarction and were initially treated by maximal medical treatment. Nevertheless, the patients' symptoms had gradually worsened, thus we performed emergency STA–MCA bypass for both cases. Postoperatively, deterioration of imaging and neurological findings was successfully stopped and the patients' condition gradually stabilized. An urgent STA–MCA bypass can be considered as a last resort to prevent progressive neurological deterioration for patients with progressive infarction due to ICA stenosis/occlusion concomitant with contralateral ICA stenosis/occlusion.

Abstract
BackgroundSystemic sclerosis (SSc) is an autoimmune disease that is characterized by systemic vasculopathy and fibrosis. Pulmonary hypertension (PH), defined as elevated pulmonary arterial pressure (PAP), is one of the leading causes of death of SSc1. In recent years, various therapies have been developed to target each of the pathogenesis of SSc – autoimmunity, vasculopathy, and fibrosis. Accordingly, treatment strategies based on risk stratification for PH progression are aspired; however, prediction of changes in PAP in diverse patients with SSc has not been established2.ObjectivesTo visualize the patterns of PAP elevation in SSc and to identify the clinical characteristics of each trajectory, by applying latent trajectory modeling for PAP measured repeatedly by echocardiography.MethodsThis was a multicenter, retrospective cohort study conducted at four referral hospitals in Kyoto, Japan. Patients with SSc who visited the study site between April 2008 and March 2021 and had at least three echocardiographic measurements of systolic pulmonary arterial pressure (sPAP) were included in this study. Follow-up concluded in March 2021. A group-based trajectory model3 was applied to the change in sPAP over time, and individual patients were classified into distinct subgroups that followed similar trajectories. The number and shape of the trajectories were estimated based on adequacy, goodness of fit, parsimony, and interpretability of the model. Clinical plausibility was assessed by comparing PH-free survival, i.e., time to either PH or death, for each trajectory. Multinomial logistic regression analysis was performed for baseline clinical characteristics associated with trajectory assignment.ResultsA total of 236 patients with a total of 1097 sPAP measurements were included. We identified five trajectories following the quadratic function as “rapid progression (n=9, 3.8%)”, “early elevation (n=30, 12.7%)”, “mid elevation (n=54, 22.9%)”, “late elevation (n=24, 10.2%)”, and “low stable (n=119, 50.4%)”. Each trajectory, in this order, showed earlier elevation of sPAP and shorter PH-free survival (Figure 1). In the multinomial logistic regression (with the “low stable” as reference), cardiac involvement was associated with the “rapid progression” (adjusted odds ratio [OR] 28.9, 95% confidence interval [CI] 3.21–259.5), diffuse cutaneous SSc was associated with the “early elevation” (OR 4.08, 95% CI 1.27–13.1), anti-centromere antibody positive was associated with the “mid elevation” (OR 4.50, 95% CI 1.11–18.2), and older age of onset was associated with the above three trajectories.ConclusionThe pattern of changes in pulmonary artery pressure over time in SSc can be classified into five distinct trajectories. Each trajectory differed in baseline clinical characteristics and outcomes.References[1]Pokeerbux MR, et al.
