Abstract
Blazars are active galactic nuclei (AGN) with relativistic jets whose non-thermal radiation is extremely variable on various timescales1-3. This variability seems mostly random, although some quasi-periodic oscillations (QPOs), implying systematic processes, have been reported in blazars and other AGN. QPOs with timescales of days or hours are especially rare4 in AGN and their nature is highly debated, explained by emitting plasma moving helically inside the jet5, plasma instabilities6,7 or orbital motion in an accretion disc7,8. Here we report results of intense optical and γ-ray flux monitoring of BL Lacertae (BL Lac) during a dramatic outburst in 2020 (ref. 9). BL Lac, the prototype of a subclass of blazars10, is powered by a 1.7 × 108 MSun (ref. 11) black hole in an elliptical galaxy (distance = 313 megaparsecs (ref. 12)). Our observations show QPOs of optical flux and linear polarization, and γ-ray flux, with cycles as short as approximately 13 h during the highest state of the outburst. The QPO properties match the expectations of current-driven kink instabilities6 near a recollimation shock about 5 parsecs (pc) from the black hole in the wake of an apparent superluminal feature moving down the jet. Such a kink is apparent in a microwave Very Long Baseline Array (VLBA) image.

Abstract
Background Although several assays are used to measure anti-receptor-binding domain (RBD) antibodies induced after severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) vaccination, the assays are not fully comparable in practice. This study evaluated the immunogenicity of the BNT162b2 mRNA vaccine in healthy adults using two immunoassays. Methods This prospective cohort study included SARS-CoV-2-naïve adults, predominantly healthcare workers, aged 20–64 years, who received two BNT162b2 vaccine doses between March and May 2021. Blood samples were collected before the first vaccination (S0), before the second vaccination (S1), 4 weeks after the second vaccination (S2), and 6 months after the second vaccination (S3). anti-RBD antibodies were measured using the Architect SARS-CoV-2 IgG II Quant (Abbott Laboratory) and Elecsys anti-SARS-CoV-2 S (Roche Diagnostics) assays. Results Among the 385 participants, the geometric mean antibody titers (GMTs) on the Architect assay (AU/mL) were 7.5, 693, 7007, and 1030 for S0, S1, S2, and S3, respectively. The corresponding GMTs on the Elecsys assay (U/mL) were 0.40, 24, 928, and 659, respectively. The GMT ratio (S3/S2) was 0.15 on the Architect and 0.71 on the Elecsys assay. The correlation between antibody titers measured with the two assays were strong at all time points after vaccination (Spearman's correlation coefficient: 0.74 to 0.86, P < 0.01 for all). GMT was significantly lower in the older age group after vaccination (P < 0.01), with no significant differences according to sex. Seroprotection (≥5458 AU/mL on the Architect assay and ≥ 753 U/mL on the Elecsys) at each time point was 0 %, 1 %, 67 %, and 1 % on the Architect assay and 0 %, 1 %, 62 %, and 43 % on the Elecsys, respectively. Conclusions Two BNT162b2 vaccine doses resulted in adequate anti-RBD antibody response, which varied by age. As the two assays showed different kinetics, the results of single immunoassays should be interpreted with caution.

Abstract
INTRODUCTION To prospectively clarify whether endoscopic contact laser vaporization of the prostate (CVP) can be safely performed even in patients undergoing antithrombotic therapy. METHODS Fifty-five patients treated with CVP were enrolled. Patients were assigned to: (i) the antithrombotic therapy group (n = 21, 38%); or (ii) control group without antithrombotic therapy (n = 34, 62%). All patients in the antithrombotic therapy group continued all antithrombotic agents during the perioperative period and thereafter. RESULTS No difference was noted in patient background between the two groups. In primary endpoints, decreases in the postoperative hemoglobin level were remarkable in the antithrombotic therapy group, while no serious effects were noted in either group. The control and antithrombotic therapy groups did not show a significant difference in the occurrence of catheter obstruction due to blood clots or serious hematuria following catheter removal. During follow-up, transurethral coagulation for hemostasis was needed only in the antithrombotic therapy group, with a frequency of transurethral coagulation of up to 14%. In secondary endpoints, no difference in the occurrence of perioperative or late-onset complications after surgery was noted between the two groups. Finally, no difference was noted in improvements in the International Prostate Symptom Score (IPSS), IPSS quality of life score, overactive bladder symptom score, maximum flow rate, or post-voiding residual urine volume between the two groups throughout the follow-up period. CONCLUSIONS CVP can be performed safely and effectively in patients undergoing continuous antithrombotic therapy. However, the possibility of secondary bleeding after discharge in a subset of patients, such as those undergoing antithrombotic therapy, may be noted.

Abstract
BACKGROUND Analysis of long noncoding RNA (lncRNA) localisation at both the tissue and subcellular levels can provide important insights into the cell types that are important for their function. METHODS By applying new fluorescent in situ hybridisation technique called hybridisation chain reaction (HCR), we achieved a high-throughput lncRNA visualisation and evaluation of clinical samples. RESULTS Assessing 1728 pairs of 16 lncRNAs and clear-cell renal-cell carcinoma (ccRCC) specimens, three lncRNAs (TUG1, HOTAIR and CDKN2B-AS1) were associated with ccRCC prognosis. Furthermore, we derived a new lncRNA risk group of ccRCC prognosis by combining the expression levels of these three lncRNAs. Examining genomic alterations underlying this classification revealed prominent features of tumours that could serve as potential biomarkers for targeting lncRNAs. We then derived combination of HCR with expansion microscopy and visualised nanoscale-resolution HCR signals in cell nuclei, uncovering intracellular colocalization of three lncRNA (TUG1, HOTAIR and CDKN2B-AS1) signals such as those located intra- or out of the nucleus or nucleolus in cancer cells. CONCLUSION LncRNAs are expected to be desirable noncoding targets for cancer diagnosis or treatments. HCR involves plural probes consisting of small DNA oligonucleotides, clinically enabling us to detect cancerous lncRNA signals simply and rapidly at a lower cost.

Abstract
The purpose of this study was to investigate factors predicting the sensitivity to cabazitaxel therapy in metastatic castration‐resistant prostate cancer (mCRPC) patients with phosphatase and tensin homolog deleted from chromosome 10 (PTEN) alterations. This single‐institution, retrospective study included 12 mCRPC patients with PTEN alterations who had received cabazitaxel therapy. Five patients (41%) responded to cabazitaxel therapy with a prostate‐specific antigen (PSA) level decline of ≥30% from baseline, and all of them had responded to prior docetaxel therapy with a PSA decline of ≥30%. None of the patients with a poor response to prior docetaxel therapy responded well to cabazitaxel therapy. Of the seven patients who did not respond to cabazitaxel and whose PSA declined from baseline was <30%, five (71%) were also refractory to prior docetaxel therapy. The PSA responses to docetaxel and cabazitaxel were significantly correlated (p = 0.027). Kaplan–Meier analysis revealed that progression‐free survival (PFS) for cabazitaxel was significantly shorter for prior docetaxel nonresponders (3.3 versus 9.1 months, p = 0.028). Multivariate analysis revealed that a poor response to prior docetaxel (PSA decline < 30%) (hazard ratio [HR] = 6.382, 95% confidence interval [CI] 1.172–34.750, p = 0.032) and baseline PSA of ≥20 ng/ml (HR = 33.584, 95% CI 2.332–483.671, p = 0.010) were independent prognostic factors for PFS with cabazitaxel therapy. These results demonstrate cross‐resistance between docetaxel and cabazitaxel. The response to prior docetaxel therapy can influence the sensitivity to cabazitaxel therapy in mCRPC patients with PTEN alterations.

Abstract
PURPOSE Inguinal hernia (IH) after radical prostatectomy (RP) is a complication that impairs quality of life; however, the factors contributing to IH after RP remain unclear. Therefore, we herein attempted to identify the factors responsible for the development of IH after RP. METHODS We reviewed 622 patients who underwent laparoscopic or robot-assisted laparoscopic RP at our hospital between December 2011 and April 2020. The total fat area and visceral fat area were calculated at the level of the umbilicus using computed tomography, and the subcutaneous fat area (SFA) was calculated by subtracting the visceral fat area from the total fat area. The psoas muscle area was measured at the third lumbar vertebrae level using computed tomography to calculate the psoas muscle mass index, which is used in sarcopenia as an index of muscle mass. We investigated the risk factors for IH after laparoscopic or robot-assisted laparoscopic RP. RESULTS IH developed in 88 patients (16.7%). Fifty-seven of these patients underwent hernia repair at our hospital, and 56 (98.2%) had indirect hernias. A multivariate analysis identified SFA (odds ratios: 0.383, p < 0.001) as an independent predictor for the development of IH. Two-year IH-free survival rates were 77.3% in the small SFA group (SFA < 123 cm2) and 88.7% in the large SFA group (SFA ≥ 123 cm2) (p < 0.001). CONCLUSION Subcutaneous fat was associated with the development of IH, particularly indirect IH, after laparoscopic or robot-assisted laparoscopic RP. An indirect IH prevention technique needs to be considered, particularly for patients with less subcutaneous fat.

Abstract
e16518 Background: With the induction of molecular targeted agents, which interfere with proteins that play critical roles in tumor growth and progression, and immune checkpoint inhibitors, the scenario of systemic treatment of metastatic renal cell carcinoma (mRCC) have dramatically been changed with improved survival. Prognostic risk assessment is essential for choosing the most appropriate first line treatment option, with selection based on International Metastatic RCC Database Consortium (IMDC) Risk Category. This study was designed to evaluate the actual efficacy of a single agent systemic therapy in the IMDC favorable risk group patients with mRCC. Methods: A total of 240 patients with mRCC who received systemic therapy were retrospectively reviewed (Institutional review board approval No 2013-0425). Among them, 55 patients were classified as favorable risk group based on the IMDC Risk Category and received a single agent systemic therapy. Clinical and pathological data were retrieved and analyzed retrospectively. The prognostic effect of each marker on overall survival (OS) was investigated with univariate and multivariate Cox’s proportional hazards regression models. Results: After a median follow-up of 46 months after first-line treatment initiation, the median progression free survival (PFS) for first line treatment and OS of patients in favorable risk group were 29 months (95% CI 21–34)) and not reached, respectively. The estimated percentage of patients who were alive at 12 and 24 months were 96 and 94%, respectively. Multivariate analysis revealed that the long-term duration of first-line treatment (hazard ratio [HR]: 0.97, 95% confidence interval [CI]: 0.94–0.99, p = 0.0299) and the metastases limited to lung (HR: 3.85, 95% CI: 1.08–24.50, p = 0.0361) were independent predictors for longer OS in favorable risk mRCC patients. Conclusions: First-line systemic therapy for favorable risk mRCC patients with a single agent resulted in relatively longer PFS and OS. A longer duration of first-line treatment and lung only metastases are correlated with longer OS.

Abstract
BackgroundClinical remission is a clinical goal in the treatment of rheumatoid arthritis (RA). Sustained, biologics-free and true remission is an unachieved goal of the “treat-to-target” approach in most patients, and the determinants for achievement are still unclear. In our recent prospective study using multiomics analysis, we proposed that a molecular signature in peripheral whole blood can be a predictor for subsequent disease activity or activities of daily living.1 We also showed that tocilizumab (TCZ) induced deep clinical remission associated with gene expression in peripheral CD4+ T cells.2ObjectivesTo consolidate and expand our hypothesis, we investigated the significance of molecular signatures in sustained remission in a larger scale cohort.MethodsTo build and validate the diagnostic model, we collected 73 peripheral blood samples from 30 patients with active RA, 30 patients in clinical remission induced by TCZ and 13 healthy controls. We then collected another 23 samples at a point before TCZ was halted due to sustained clinical remission. In total, 96 samples were analyzed by a multiomics platform, which included RNA sequencing and comprehensive proteomics.ResultsWe first developed an optimized partial least-squares regression (PLSR) model using data from 5,436 genes and 255 proteins extracted in our previous model.1 The odds ratio in the model clearly reflected the clinical state with high fidelity (Figure 1). In that study, TCZ induced nearly half of the patients with clinical remission into molecular remission, with an odds ratio of less than zero. To clarify the characteristics of the molecular signature at sustained clinical remission under TCZ continuation, 23 samples were applied to the model. The odds ratio was largely the same as that for clinical remission. Next, we investigated the association with disease flare after cessation of TCZ. At some points before cessation, the median odds ratio in patients who experienced disease flare after stopping TCZ tended to be higher than that in patients with sustained remission after stopping TCZ in the transcriptomics model but not in the proteomics model. Thirty-five differentially expressed genes were identified between the two groups under the conditions of a >1.5-fold change and P-value<0.05.Figure 1.Odds ratio in the partial least-squares regression model using transcriptomics (A) and proteomics (B) data from rheumatoid arthritis and healthy control groupsConclusionOur larger scale study validated the idea in our previous study that TCZ induces molecular remission. A certain substantial gap associated with prognosis after quitting TCZ may exist as a molecular signature of sustained clinical remission induced by TCZ. These multiomics data sets enable us to understand sustained clinical remission at a molecular level.References[1]Nat Commun. 9(1):2775, 2018, 2) Sci Rep.11(1):16691, 2021Graphs:AcknowledgementsWe acknowledge funding by Chugai Pharmaceutical Co., Ltd.Disclosure of InterestsNobuhiko Kajio: None declared, Katsuya Suzuki Speakers bureau: AbbVie, AsahiKasei, Astellas, Ayumi, Bristol-Myers Squibb, Chugai, Eisai, Eli Lilly, Gilead, Janssen, Mitsubishi Tanabe, Pfizer, Sanofi, Viatris, Consultant of: AbbVie, Asahi Kasei, Janssen, Pfizer, Grant/research support from: Chugai, Daiichi-Sankyo, Eli Lilly, Mitsubishi Tanabe, Ono, Takeda, Kotaro Matsumoto: None declared, Hiroshi Iijima: None declared, Seiji Nakamura: None declared, Yohei Ishizawa: None declared, Jun Inamo: None declared, Masaru Takeshita: None declared, Keiko Yoshimoto: None declared, Yuko Kaneko Speakers bureau: Chugai, Consultant of: Chugai, Grant/research support from: Chugai, Tsutomu Takeuchi Speakers bureau: Chugai, Consultant of: Chugai, Grant/research support from: Chugai.

Abstract
The pyrolysis of biomass material results in pyroligneous acid (PA) and biochar, among other by-products. In agriculture, PA is recognized as an antimicrobial agent, bio-insecticide, and bio-herbicide due to antioxidant activity provided by a variety of constituent materials. Application of PA to crop plants and soil can result in growth promotion, improved soil health, and reduced reliance on polluting chemical crop inputs. More detailed information regarding chemical compound content within PA and identification of optimal chemical profiles for growth promotion in different crop species is essential for application to yield effective results. Additionally, biochar and PA are often applied in tandem for increased agricultural benefits, but little is known regarding the optimal proportion of each crop input. This work reports on the effect of combined applications of different proportions of PA (200- and 800-fold dilutions) and chemical fertilizer rates (100%, 75%, 50%, and 0%) in the presence or absence of biochar on Komatsuna (Brassica rapa var. perviridis, Japanese mustard spinach) plant growth. To elucidate the chemical composition of the applied PA, four different spectroscopic measurements of fluorescence excitation were utilized for analysis—excitation-emission matrix, ion chromatography, high-performance liquid chromatography, and gas chromatography-mass spectrometry. It was determined that PA originating from pyrolysis of Japanese pine wood contained different classes of biostimulants (e.g., tryptophan, humic acid, and fulvic acid), and application to Komatsuna plants resulted in increased growth when applied alone, and in different combinations with the other two inputs. Additionally, application of biochar and PA at the higher dilution rate increased leaf accumulation of nutrients, calcium, and phosphorus. These effects reveal that PA and biochar are promising materials for sustainable crop production.

Abstract
Hydronephrosis in extramammary Paget's disease (EMPD) with distant metastasis (metastatic EMPD) has been observed in medical practice; however, its prognosis remains unclear. Retrospective analyses were performed to assess the management and outcomes of hydronephrosis in metastatic EMPD. During a follow-up of 44 patients with metastatic EMPD, 13 (30%) developed hydronephrosis. Ten (77%) of the 13 patients with hydronephrosis had impaired renal function (estimated glomerular filtration rate: <60 ml/min/1.73 m2 ), and ureteral stents were placed in every patient with impaired renal function. The stent was placed successfully in all 10 patients, and their renal function recovered within a median period of 7 days. Importantly, each of these patients continued chemotherapy, and none of them experienced stent failure. The median overall survival time (OS) in patients with metastatic EMPD and hydronephrosis (n = 13) was 7.8 months. Treatment for hydronephrosis was not a significant factor for OS, and median OS in patients who underwent ureteral stent replacement (n = 10) was 14.7 months. Collectively, our results indicate that hydronephrosis is relatively common, and ureteral stent placement should be considered in cases of metastatic EMPD with hydronephrosis to maintain renal function and continue chemotherapy toward a better prognosis.

Abstract
INTRODUCTION Many patients experience anxiety, not limited to claustrophobia, before magnetic resonance imaging (MRI) examination. We performed a non-randomized controlled trial to evaluate whether a patient-friendly audiovisual (AV) system in the MR scanner room reduces patient anxiety. METHODS We randomly selected 61 participants from outpatients who required brain MRI examination. Patients were informed that they could choose to undergo an MRI examination with a patient-friendly AV system (Ambient Experience, Philips Healthcare, Best, The Netherlands) or the standard system. To complete the MRI examination without affecting clinical practice, all patients who preferred the patient-friendly AV system were assigned to the preferring AV group. Patients who indicated that either system was acceptable were randomly assigned to the no preference but allocated AV group or control (using the standard system) groups. In both groups, state anxiety using the State-Trait Anxiety Inventory (STAI) was assessed before and after the MRI examination (A-State-before and A-State-after MRI, respectively). The changes in A-State-before and A-State-after MRI were categorized as follows: relieved high-state anxiety, no change in high-state anxiety, stable easiness, and intensified anxiety. RESULTS Among the 61 included patients, 19 were assigned to the preferring AV group, 20 to the no preference but allocated AV group, and 22 to the control group. There were no significant differences between the group. However, in patients with high-state anxiety before MRI, the preferring AV group and the no preference but allocated AV group, which used the patient-friendly AV system, relieved high-state anxiety by 63.6% (7 of 11 patients) and 81.8% (9 of 11 patients), respectively. In contrast, the control group using the standard system relieved high-level anxiety by only 42.9% (three out of seven patients). CONCLUSION The patient-friendly AV system may reduce anxiety in patients undergoing MRI examinations. IMPLICATIONS FOR PRACTICE The patient-friendly AV system may reduce anxiety in patients undergoing MRI examination by providing a more patient-centered MRI examination environment. These findings may help ameliorate negative perceptions associated with MRI examination.

Abstract
The Hayabusa2 spacecraft investigated the C-type (carbonaceous) asteroid (162173) Ryugu. The mission performed two landing operations to collect samples of surface and subsurface material, the latter exposed by an artificial impact. We present images of the second touchdown site, finding that ejecta from the impact crater was present at the sample location. Surface pebbles at both landing sites show morphological variations ranging from rugged to smooth, similar to Ryugu's boulders, and shapes from quasi-spherical to flattened. The samples were returned to Earth on 6 December 2020. We describe the morphology of >5 grams of returned pebbles and sand. Their diverse color, shape, and structure are consistent with the observed materials of Ryugu; we conclude that they are a representative sample of the asteroid.

[PMID: 34980039 PMCID: PMC8722180 DOI: 10.1186/s12885-021-09122-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Accepted: 12/16/2021] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND Paratesticular leiomyosarcoma (LMS) is a rare tumor. Conventionally, tumor resection by high inguinal orchiectomy is performed as the preferred treatment approach for paratesticular sarcoma. On the other hand, testis-sparing surgery has recently attracted attention as a less-invasive treatment option for paratesticular sarcoma. However, the prognostic predictors and optimal treatment strategy for paratesticular LMS remain unclear because of its rarity. In this study, we systematically reviewed previously reported cases of paratesticular LMS to evaluate the prognostic factors and establish the optimal treatment strategy. METHODS A systematic search of Medline, Web of Science, Embase, and Google was performed to find articles describing localized paratesticular LMS published between 1971 and 2020 in English. The final cohort included 217 patients in 167 articles. The starting point of this study was the time of definitive surgical treatment, and the end point was the time of local recurrence (LR), distant metastasis (DM), and disease-specific mortality. RESULTS Patients with cutaneous LMS had a slightly better LR-free survival, DM-free survival, and disease-specific survival than those with subcutaneous LMS (p = 0.745, p = 0.033, and p = 0.126, respectively). Patients with higher grade tumors had a significantly higher risk of DM and disease-specific mortality (Grade 3 vs Grade 1 p < 0.001, and Grade 3 vs Grade 1 p < 0.001, respectively). In addition, those with a microscopic positive margin had a significantly higher risk of LR and DM than those with a negative margin (p < 0.001, and p = 0.018, respectively). Patients who underwent simple tumorectomy had a slightly higher risk of LR than those who underwent high inguinal orchiectomy (p = 0.067). Subgroup analysis of cutaneous LMS demonstrated that the difference in LR between simple tumorectomy and high inguinal orchiectomy was limited (p = 0.212). On the other hand, subgroup analysis of subcutaneous LMS revealed a significant difference in LR (p = 0.039). CONCLUSIONS Our study demonstrated that subcutaneous LMS and high-grade tumors are prognostic factors for paratesticular LMS. For subcutaneous LMS, tumorectomy with high inguinal orchiectomy should be the optimal treatment strategy to achieve a negative surgical margin.

Abstract
BACKGROUND Prostate cancer harboring cyclin-dependent kinase 12 (CDK12) abnormalities is a hot topic due to its distinctive clinical features, such as sensitivity to immune checkpoint inhibitors. In the last few years, precision medicine using comprehensive genome sequencing has become familiar, and the era of precision oncology has arrived in the field of prostate cancer. This study aimed to present the demographic characteristics of patients with CDK12 alterations. METHODS In 12 patients with detected CDK12 alterations in our hospital between 2015 and 2021, we evaluated their genomic features and clinical course. CDK12 allelic status was classified into three groups: monoallelic loss, potentially biallelic loss, and biallelic loss based on the genome analyses. RESULTS Seven patients already had metastatic cancer at the time of diagnosis, and all 12 patients had Gleason grade ≥ 4. Most cases of biallelic loss or potentially biallelic loss were metastatic cancers at the initial staging, and all these cases were categorized into Gleason grade 5. Two of the 12 patients had BRCA2/RB1 co-loss, and the other two had whole genome duplication. Five patients had a long-term survival of > 6 years, but two patients died within 4 years of diagnosis. CONCLUSION This is the first Japanese prostate cancer case series with CDK12 alterations. CDK12-altered prostate cancer is a heterogeneous disease, and accumulating cases with detailed information leads to precision oncology.

Abstract
To stratify the heterogeneity of prostate cancer (PCa) with seminal vesicle invasion (SVI) immunologically after radical prostatectomy focusing on the tumor microenvironment. We retrospectively reviewed the clinicopathological data of 71 PCa patients with SVI, which is known as a factor of very high-risk PCa. Preoperative clinical variables and postoperative pathological variables were evaluated as predictors of biochemical recurrence (BCR) with a multivariate logistic regression. Immune cell infiltration including the CD8-positive cell (CD8+ cell) and CD204-positive M2-like macrophage (CD204+ cell) was investigated by immunohistochemistry. The cumulative incidence and risk of BCR were assessed with a Kaplan-Meier analysis and competing risks regression. A higher CD8+ cell count in the SVI area significantly indicated a favorable prognosis for cancers with SVI (p = 0.004). A lower CD204+ cell count in the SVI area also significantly indicated a favorable prognosis for cancers with SVI (p = 0.004). Furthermore, the combination of the CD8+ and CD204+ cell infiltration ratio of the SVI area to the main tumor area was a significant factor for BCR in the patients with the PCa with SVI (p = 0.001). In PCa patients with SVI, the combination of CD8+ and CD204+ cell infiltration is useful to predict the prognosis.

Abstract
We have successfully isolated and characterized the zinc carbamate complex (phen)Zn(OAc)(OC(=O)NHPh) (1; phen=1,10-phenanthroline), formed as an intermediate during the Zn(OAc)2 /phen-catalyzed synthesis of organic carbamates from CO2 , amines, and the reusable reactant Si(OMe)4 . Density functional theory calculations revealed that the direct reaction of 1 with Si(OMe)4 proceeds via a five-coordinate silicon intermediate, forming organic carbamates. Based on these results, the catalytic system was improved by using Si(OMe)4 as the reaction solvent and additives like KOMe and KF, which promote the formation of the five-coordinated silicon species. This sustainable and effective method can be used to synthesize various N-aryl and N-alkyl carbamates, including industrially important polyurethane raw materials, starting from CO2 under atmospheric pressure.

Abstract
OBJECTIVE Pheochromocytoma is a rare neuroendocrine tumour that secretes catecholamines and originates in the adrenal gland. Although surgical resection is the only curative therapy for pheochromocytoma, it is associated with a risk of haemodynamic instability (HDI), such as extremely high blood pressure and/or post tumour removal hypotension and shock. We investigated the risk factors for HDI during pheochromocytoma surgery. DESIGN AND PATIENTS Eighty-two patients who underwent laparoscopic adrenalectomy for pheochromocytoma between July 2002 and February 2020 were examined. We excluded 3 patients with bilateral disease and 11 without detailed 24 h urinary data. We defined HDI as systolic blood pressure ≥ 200 or <80 mmHg. We investigated the risk factors for HDI during laparoscopic adrenalectomy for pheochromocytoma. RESULTS There were 29 males and 39 females with a median age of 50.5 years. Tumours were localised on the right adrenal gland in 28 patients and on the left in 40. The median tumour diameter was 37.5 mm and the median pneumoperitoneum time was 93.5 min. Twenty-five out of sixty-eight patients (37%) developed HDI. A multivariate analysis identified diabetes mellitus (DM; odds ratio: 3.834; 95% confidence interval: 1.062-13.83; p = .04) as an independent predictor of HDI. In terms of hormonal data, median 24 h urinary epinephrine levels (p = .04) and metanephrine levels (p = .01) were significantly higher in the HDI group. DM was also considered as a risk factor for prolonged HDI (p = .02). CONCLUSION Surgeons and anaesthesiologists need to be aware of the risk of HDI and its prolongation during laparoscopic adrenalectomy for pheochromocytoma for DM patients.
