Abstract
BACKGROUND Individuals with Down syndrome (DS) exhibit deficits in static and dynamic balance abilities and maladaptive functions. This study aimed to determine the effectiveness of dance movement therapy (DMT) group intervention in individuals with DS. METHODS The 31 participating individuals with DS, aged 5-29 years, were randomly divided into intervention (n = 16) and control (n = 15) groups. Posturography was used for static balance measurement, timed up and go test for dynamic balance measurement and the Achenbach System of Empirically Based Assessment (ASEBA) questionnaire for adaptive function and behavioural problem measurement in participants before and after the DMT interventions. The intervention group underwent 60-min DMT intervention once a week for 10 times, while the control group had usual daily activities. RESULTS The results revealed a statistically significant difference and large effect sizes in dynamic balance [(f(1, 29) = 4.52, P = 0.04, ηp 2 = 0.14)] in the intervention group compared with the control group. There were no statistically significant differences in static balance and ASEBA scores between the groups. CONCLUSIONS This study found that the DMT interventions helped to improve the dynamic balance in individuals with DS.

Abstract
A half-wave plate (HWP) is often used as a modulator to suppress systematic error in the measurements of cosmic microwave background (CMB) polarization. A HWP can also be used to measure circular polarization (CP) through its optical leakage from CP to linear polarization. The CP of the CMB is predicted from various sources, such as interactions in the Universe and extension of the standard model. Interaction with supernova remnants of population III stars is one of the brightest CP sources. Thus, the observation of the CP of CMB is a new tool for searching for population III stars. In this paper, we demonstrate the improved measurement of the leakage coefficient using the transmission measurement of an actual HWP in the laboratory. We measured the transmittance of linearly polarized light through the HWP used in Polarbear in the frequency range of 120-160 GHz. We evaluate the properties of the HWP by fitting the data with a physical model using the Markov Chain Monte Carlo method. We then estimate the band-averaged CP leakage coefficient using the physical model. We find that the leakage coefficient strongly depends on the spectra of CP sources. We thus calculate the maximum fractional leakage coefficient from CP to linear polarization as 0.133 ± 0.009 in the Rayleigh-Jeans spectrum. The nonzero value shows that Polarbear has a sensitivity to CP. Additionally, because we use the bandpass of detectors installed in the telescope to calculate the band-averaged values, we also consider systematic effects in the experiment.

Abstract
BACKGROUND The Tokyo Guidelines 2018 proposed fundus-first laparoscopic cholecystectomy (FFLC) as a bailout surgery. This study investigated the clinical impact of FFLC for severe cholecystitis. METHODS This study reviewed 772 patients who underwent laparoscopic cholecystectomy (LC) between 2015 and 2018. Of these patients, 171 patients were diagnosed with severe cholecystitis according to our difficulty scoring system. FFLC was not prevalent in our faculty for the first 2 years [early period group (EG)], whereas FFLC was predominantly used for the last 2 years [late period group (LG)]. There were 81 patients (47%) belonging to the EG and 90 patients (53%) in the LG. The clinical data and the surgical outcomes of these patients were retrospectively analyzed. RESULTS The difficulty score did not differ between the two groups (11 vs. 11 points, p = 0.846). Patients underwent FFLC significantly more frequently in the LG (63% vs. 12%, p = 0.020). Laparoscopic subtotal cholecystectomy (LSC) was done in 10 patients (11%) of the LG, which was significantly low compared to that in the EG (n = 20, 25%) (p = 0.020). In all patients, LC was safely achieved without bile duct injury or conversion to laparotomy. The incidence of choledocholithiasis was significantly low in the LG (0 vs. 4, p = 0.048). The median postoperative hospital stay was significantly shorter in the LG (6 vs. 4 days, p < 0.001). CONCLUSION After the introduction of FFLC, there were significant improvements in the surgical outcomes of LC for severe cholecystitis, including the rate of LSC, incidence of choledocholithiasis, and duration of postoperative hospital stay.

Abstract
We present the first search for the pair production of dark particles X via K_{L}^{0}→XX with X decaying into two photons using the data collected by the KOTO experiment. No signal was observed in the mass range of 40-110 MeV/c^{2} and 210-240 MeV/c^{2}. This sets upper limits on the branching fractions as B(K_{L}^{0}→XX)<(1-4)×10^{-7} and B(K_{L}^{0}→XX)<(1-2)×10^{-6} at the 90% confidence level for the two mass regions, respectively.

Abstract
Background The criteria for deciding upon non-operative management for nonocclusive mesenteric ischemia (NOMI) are poorly defined. The aim of this study is to determine the prognostic factors for survival in conservative treatment of NOMI. Methods Patients with bowel ischemia were identified by searching for “ICD-10 code K550” in the Diagnosis Procedure Combination database between June 2015 and May 2020. A total of 457 patients were extracted and their medical records, including the clinical factors, imaging findings and outcomes, were analyzed retrospectively. Diagnosis of NOMI was confirmed by the presence of specific findings in contrast-enhanced multidetector-row CT. Twenty-six patients with conservative therapy for NOMI, including four cases of explorative laparotomy or laparoscopy, were enrolled. Results Among the 26 cases without surgical intervention, eight patients (31%) survived to discharge. The level of albumin was significantly higher, and the levels of lactate dehydrogenase, total bilirubin, C-reactive protein, and lactate were significantly lower in the survivors than the non-survivors. Sepsis-related Organ Failure Assessment (SOFA) score was significantly lower in the survivors than the non-survivors. The most reliable predictor of survival for NOMI was SOFA score (cutoff value ≤ 3 points), which had the highest AUC value (0.899) with odds ratio of 0.075 (CI: 0.0096–0.58). Conclusions The SOFA score and several biological markers are promising predictors to determine a treatment plan for NOMI and to avoid unnecessary laparotomy.

Abstract
Here, we evaluated the reduction efficiencies of indigenous pepper mild mottle virus (PMMoV, a potential surrogate for human enteric viruses to assess virus removal by coagulation-sedimentation-rapid sand filtration [CS-RSF] and coagulation-microfiltration [C-MF]) and representative human enteric viruses in four full-scale drinking water treatment plants that use CS-RSF (Plants A and B) or C-MF (Plants C and D). First, we developed a virus concentration method by using an electropositive filter and a tangential-flow ultrafiltration membrane to effectively concentrate and recover PMMoV from large volumes of water: the recovery rates of PMMoV were 100% when 100-L samples of PMMoV-spiked dechlorinated tap water were concentrated to 20 mL; even when spiked water volume was 2000 L, recovery rates of >30% were maintained. The concentrations of indigenous PMMoV in raw and treated water samples determined by using this method were always above the quantification limit of the real-time polymerase chain reaction assay. We therefore were able to determine its reduction ratios: 0.9-2.7-log10 in full-scale CS-RSF and 0.7-2.9-log10 in full-scale C-MF. The PMMoV reduction ratios in C-MF at Plant C (1.0 ± 0.3-log10) were lower than those in CS-RSF at Plants A (1.7 ± 0.5-log10) and B (1.4 ± 0.7-log10), despite the higher ability of MF for particle separation in comparison with RSF owing to the small pore size in MF. Lab-scale virus-spiking C-MF experiments that mimicked full-scale C-MF revealed that a low dosage of coagulant (polyaluminum chloride [PACl]) applied in C-MF, which is determined mainly from the viewpoint of preventing membrane fouling, probably led to the low reduction ratios of PMMoV in C-MF. This implies that high virus reduction ratios (>4-log10) achieved in previous lab-scale virus-spiking C-MF studies are not necessarily achieved in full-scale C-MF. The PMMoV reduction ratios in C-MF at Plant D (2.2 ± 0.6-log10) were higher than those at Plant C, despite similar coagulant dosages. In lab-scale C-MF, the PMMoV reduction ratios increased from 1-log10 (with PACl [basicity 1.5], as at Plant C) to 2-4-log10 (with high-basicity PACl [basicity 2.1], as at Plant D), suggesting that the use of high-basicity PACl probably resulted in higher reduction ratios of PMMoV at Plant D than at Plant C. Finally, we compared the reduction ratios of indigenous PMMoV and representative human enteric viruses in full-scale CS-RSF and C-MF. At Plant D, the concentrations of human norovirus genogroup II (HuNoV GII) in raw water were sometimes above the quantification limit; however, whether its reduction ratios in C-MF were higher than those of PMMoV could not be judged since reduction ratios were >1.4-log10 for HuNoV GII and 2.3-2.9-log10 for PMMoV. At Plant B, the concentrations of enteroviruses (EVs) and HuNoV GII in raw water were above the quantification limit on one occasion, and the reduction ratios of EVs (>1.2-log10) and HuNoV GII (>1.5-log10) in CS-RSF were higher than that of PMMoV (0.9-log10). This finding supports the usefulness of PMMoV as a potential surrogate for human enteric viruses to assess virus removal by CS-RSF.

Abstract
A 55-year-old man underwent Hartmann's procedure for generalized peritonitis caused by perforation of sigmoid colon cancer, which was histologically diagnosed as tubular adenocarcinoma penetrating the muscularis propria (T3). The extent of lymph node dissection was insufficient for the advanced cancer, according to the concept of complete mesocolic excision. Two months after surgery, he underwent laparoscopic Hartmann's reversal, combined with interval lymphadenectomy. En bloc resection of the colostomy, rectal stump and associated mesentery was performed with high ligation of the inferior mesenteric artery. Subsequently, the intestinal continuity was restored by end-to-end anastomosis. The postoperative course was uneventful except for infection at the stoma site. No lymph node metastasis was found by histological examination of the resected specimen, with no evidence of cancer recurrence 8 months after the initial surgery.

Abstract
With more than 5500 da Vinci Surgical System (DVSS) installed worldwide, the robotic approach for general surgery, including for inguinal hernia repair, is gaining popularity in the USA. However, in many countries outside the USA, robotic surgery is performed at only a few advanced institutions; therefore, its advantages over the open or laparoscopic approaches for inguinal hernia repair are unclear. Several retrospective studies have demonstrated the safety and feasibility of robotic inguinal hernia repair, but there is still no firm evidence to support the superiority of robotic surgery for this procedure or its long-term clinical outcomes. Robotic surgery has the potential to overcome the disadvantages of conventional laparoscopic surgery through appropriate utilization of technological advantages, such as wristed instruments, tremor filtering, and high-resolution 3D images. The potential benefits of robotic inguinal hernia repair are lower rates of complications or recurrence than open and laparoscopic surgery, with less postoperative pain, and a rapid learning curve for surgeons. In this review, we summarize the current status and future prospects of robotic inguinal hernia repair and discuss the issues associated with this procedure.

Abstract
Background Interleukin (IL)‐31 affects the inflammatory response, is involved in epidermal barrier disruption in atopic dermatitis (AD) and plays a key role in pruritus. Nemolizumab, a humanized monoclonal antibody against IL‐31 receptor A, reduced pruritus in patients with AD after a 16‐week administration period. Objectives To examine the long‐term effectiveness and safety of nemolizumab in patients aged ≥ 13 years with AD and inadequately controlled moderate‐to‐severe pruritus. Methods In two long‐term phase III studies, nemolizumab 60 mg every 4 weeks (Q4W) was administered subcutaneously, concomitantly with topical treatments. Study‐JP01 patients received double‐blind nemolizumab or placebo for 16 weeks, and then entered a 52‐week extension period in which all patients received nemolizumab (nemolizumab/nemolizumab and placebo/nemolizumab groups). Study‐JP02 patients received nemolizumab for 52 weeks. Both studies included an 8‐week follow‐up period. Results Study‐JP01 nemolizumab/nemolizumab and placebo/nemolizumab, and Study‐JP02 nemolizumab groups comprised 143, 72 and 88 patients, respectively. In the nemolizumab/nemolizumab group, there were clinically meaningful improvements from the start of treatment to week 68 in the pruritus visual analogue scale (66% decrease) and Eczema Area and Severity Index (78% decrease). Quality of life (QoL) indicators improved after the first nemolizumab dose; improvements were maintained during the follow‐up period. The long‐term safety profile was consistent with previous studies, with no unexpected late‐onset adverse events. Conclusions Nemolizumab 60 mg Q4W with concomitant topical treatments in patients with AD and inadequately controlled moderate‐to‐severe pruritus produced a continuous improvement in pruritus, signs of AD, and QoL for up to 68 weeks, with a favourable safety profile.

Abstract
AIM Drain fluid amylase concentration (DFAC) has been reported as a predictor of clinically relevant postoperative pancreatic fistula (CR-POPF) after pancreatectomy. However, the clinical significance of measuring the total drain fluid amylase amount (DFAA) considering the daily drainage volume of CR-POPF remains unclear. METHODS Data from 216 consecutive patients who underwent pancreaticoduodenectomy (PD) (n = 126) or distal pancreatectomy (DP) (n = 90) between August 2014 and November 2020 were reviewed. All drains were closed but not suctioned. DFAA was calculated by multiplying the DFAC and daily drainage fluid volume. DFAC and DFAA were recorded on d 1 and 3 after pancreatectomy. The cutoff value of CR-POPF was determined using the receiver operating characteristic curve. RESULTS CR-POPF was found in 75 patients (35%) (PD: 30%, DP: 41%, P = .111); the mortality rate was zero. The cutoff value of DFAC-day 1 was 1757 U/L (sensitivity [SE]: 84%, specificity [SP]: 62%, and accuracy [AC]: 69%). The cutoff value of DFAA-day 1 was 139 U (SE: 71%, SP: 72%, and AC: 71%). The cutoff value of DFAC-day 3 was 1044 U/L (SE: 73%, SP: 79%, and AC: 78%). The cutoff value of DFAA-day 3 was 21 U (SE: 68%, SP: 72%, and AC: 70%). Multivariate analysis indicated that a nondilated pancreatic duct and high DFAC-day 3 were independently associated with CR-POPF after PD, indicating that a prolonged operative duration, massive blood loss, and high DFAC-day 3 are independently associated with CR-POPF after DP. CONCLUSION DFAC is more reliable than DFAA for predicting CR-POPF after both PD and DP.

Abstract
Abstract
Study question
Can the gas-liquid interface organ culture system that achieved in vitro spermatogenesis in mice also support in vitro spermatogenesis in human adult testis?
Summary answer
Although the progression of spermatogenesis was not observed, germ cells were maintained without the degeneration of the architecture in both fresh and cryopreserved testicular tissues.
What is known already
Although the research on in vitro spermatogenesis have been conducted for 100 years, only the organ culture system using gas-liquid interface method achieved in vitro spermatogenesis in mice. It has not been verified whether this culture system can be applied to other mammals including humans and induce spermatogenesis.
Study design, size, duration
Testicular tissue was obtained from the transgender patients receiving sex reassignment surgery. Testicular specimens were either immediately processed for cultivation or cryopreserved, using a vitrification freezing protocol. Organ culture of testicular fragments was performed in three different media for a maximum period of 3 weeks to evaluate the short-term changes in the cultured tissues (viability, proliferation and maintenance of germ and somatic cells).
Participants/materials, setting, methods
Fresh and cryopreserved-thawed testis fragments (1–2 mm3) were cultured using the organ culture system in alpha-MEM with knock-out serum replacement (K group), alpha-MEM with lipid-rich BSA (A group) and DMEM with FBS (D group). Luteinizing hormone, follicle stimulating hormone and testosterone were supplemented. The number of germ cells (using DDX4), proliferative activity of germ cells (using EdU assay) and intratubular cell apoptosis (by TdT-mediated dUTP Nick End Labeling) were evaluated by immunohistochemical staining weekly.
Main results and the role of chance
The architecture of the seminiferous tubules was maintained until the second week of culture in both the fresh and the cryopreserved culture group. The number of DDX4-positive germ cells per seminiferous tubule in groups D, K, and A was 49 ± 24, 55 ± 21, 50 ± 26 cells/tubule in 1 day, 32 ± 13, 42 ± 7, 36 ± 21 cells/tubule in 1week, respectively. The numbers gradually decreased to 26 ± 8, 24 ± 6 and 27 ± 18 cells/tubule, in 2 weeks, respectively, with no difference among the groups. The number of intratubular EdU-positive cells of groups D, K, and A was 0.2 ± 0.2, 2.8 ± 2.1, 1.1 ± 0.8 cells/tubule at 1 day, 0.1 ± 0.2, 0.5 ± 0.6, 0.3 ± 0.6 cells/tubule at 1 week, respectively. The values were 0.01, 0.05, and 0.03 at 2 weeks. Thus, EdU-positive cells drastically decreased from the first week of culture. The number of DDX4-positive germ cells and the intratubular EdU-positive cells in the cryopreserved culture group was not different from that in the fresh culture group.
Limitations, reasons for caution
Current organ culture systems are incomplete, being unable to induce human in vitro spermatogenesis. Further research is needed to improve culture condition with the aim of producing fertile sperm of infertile adult male patients.
Wider implications of the findings: Our organ culture system could maintain testis structure and germ cells. By using the testis tissues of the transgender patients, which are available with their consent, we will promote the investigation of the culture condition necessary for germ cell proliferation and differentiation.

Abstract
In 2000, an equine Yamakagashi (Rhabdophis tigrinus) antivenom (Lot 0001) was testmanufactured as an unapproved drug for treatment of Yamakagashi bites. It was stocked on the premise of super-legal use from the viewpoint of emergency health crisis management. The antivenom showed a strong neutralizing ability against the hemorrhagic and coagulation activity of the Yamakagashi venom in its potency test. One vial of the antivenom can effectively neutralize at least about 4 mg of Yamakagashi venom. Its efficacy has also been confirmed in patients with severe cases of R. tigrinus bite that has been used in emergency. In 2020, this antivenom (Lot 0001) has reached 20 years after its production. To evaluate the integrity and potency of the antivenom, quality control, safety and potency tests had been conducted almost every year since 2012. Physical and chemical tests (property test, moisture content test, insoluble foreign matter test, osmotic pressure ratio test, pH test, protein content test, endotoxin test, sterility test) of the antivenom, showed no significant changes throughout the years, when compared to the results immediately after its production in 2000. All the parameters measured were also within the standard values. In animal safety tests (test for absence of toxicity and pyrogen), there was no change in the test results during the storage period and no abnormalities were observed. The potency test (anti-coagulant activity) after 20 years of the product, showed the same potency as those recorded immediately after production. Therefore, in all of the stability monitoring tests conducted so far, the product did not show any significant change compared to the results immediately after production. This confirms the stability of the product during the stockpiling period to the present, that is, 20 years after production.

Abstract
Background Advanced hepatocellular carcinoma (HCC) can often spread as intrahepatic metastases. Extrahepatic metastasis (e.g., lung, lymph nodes, and bones) is rare, and gallbladder metastasis from HCC is extremely rare. Case presentation A 66-year-old woman who presented with right hypochondrial pain was referred to our hospital for further examination of a liver tumor. The blood chemistry data showed elevated levels of serum α-fetoprotein (AFP) (3730 ng/mL), protein induced by vitamin K absence or antagonist II (PIVKA-II) (130 mAU/mL), and carcinoembryonic antigen (CEA) (358.6 ng/mL). Hepatitis B surface antigen and hepatitis C virus antibody were negative. Dynamic computed tomography (CT) showed a tumor measuring 12 × 7 cm in the right lobe of the liver. This tumor was contrast-enhanced in the hepatic arterial phase and then became less dense than the liver parenchyma in the portal phase. A well-enhanced tumor was found in the gallbladder. No regional lymph nodes were enlarged. Contrast-enhanced magnetic resonance imaging (MRI) demonstrated that the liver tumor showed a pattern of early enhancement and washout. The gallbladder tumor was also detected as an enhanced mass. Endoscopic retrograde cholangiography (ERC) showed compression of the left hepatic duct due to the liver tumor. The patient was diagnosed with simultaneous HCC and gallbladder cancer. Right hepatic trisectionectomy and caudate lobectomy with extrahepatic bile duct resection were performed. Histopathological examination of the resected liver specimen showed a poorly differentiated HCC cell component with a trabecular and solid growth, and diffuse invasion of the portal vein. The same tumor cells were found in the gallbladder, but no continuity with the liver tumor was identified. Immunohistochemistry of the liver tumor and gallbladder was positive for AFP, Glypican 3, and CK7, and negative for CK19. The final pathological diagnosis was the gallbladder metastasis from HCC. A follow-up diagnostic image 33 months after surgery showed a mass in the upper lobe of the left lung. The patient underwent left upper lobectomy. Postoperative pathology revealed that the lung lesion was a metastasis of HCC. The patient was still alive with lung metastasis and was being treated with a molecular-targeting drug in good health 42 months after the initial surgery. Conclusions The standard treatment for advanced HCC with extrahepatic metastases is molecularly targeted drugs, but surgery is also an option if the lesion can be resected en bloc without remnants.

Abstract
Background Symptomatic congenital biliary dilatation (CBD) during early infancy is always characterized by cystic dilation of the common bile duct with a narrow segment connecting the pancreatic duct. Case presentation In two consecutive infants with a prenatal diagnosis of CBD, we found that biliary sludge had formed in the cyst upon the appearance of symptoms including acholic stool and hypertransaminasemia. Infrared absorption spectrometry revealed that the sludge consisted of calcium bilirubinate. Conclusion We suggest that overproduction of bilirubin by neonatal hemolysis causes sedimentation of bilirubin calcium, resulting in obstruction of the narrow segment and development of symptoms.

Abstract
The rare decay K_{L}→π^{0}νν[over ¯] was studied with the dataset taken at the J-PARC KOTO experiment in 2016, 2017, and 2018. With a single event sensitivity of (7.20±0.05_{stat}±0.66_{syst})×10^{-10}, three candidate events were observed in the signal region. After unveiling them, contaminations from K^{±} and scattered K_{L} decays were studied, and the total number of background events was estimated to be 1.22±0.26. We conclude that the number of observed events is statistically consistent with the background expectation. For this dataset, we set an upper limit of 4.9×10^{-9} on the branching fraction of K_{L}→π^{0}νν[over ¯] at the 90% confidence level.

Abstract
BACKGROUND Undescended testes are associated with an increased risk of malignancy and infertility, and surgical treatment in childhood is recommended. CASE PRESENTATION A 35-year-old man presented to the emergency department with abdominal pain and vomiting. Despite a history of surgery for a left undescended testis in infancy, his left-sided scrotum appeared underdeveloped. Contrast-enhanced computed tomography showed a pelvic mass, involving a major axis of approximately 15 cm, with high-density ascites suggestive of hemorrhage. A ruptured gastrointestinal stromal tumor was suspected. As he was in hemorrhagic shock, an emergency laparotomy was indicated. The active bleeding mass was controlled through complete resection. A pathological evaluation of the mass revealed a seminoma arising from an undescended testis. His post-operative course was uneventful, and he was discharged on post-operative day 6. Recurrence on the retroperitoneal lymph nodes was detected 1 year postoperatively, and a retroperitoneal lymph node dissection was performed after chemotherapy. He remains well without any apparent signs of recurrence. CONCLUSIONS Paying close attention to an empty scrotum is advisable, even postoperatively, for undescended testis because of possible subsequent potential malignancy presenting with hemorrhage, as our patient demonstrated.

Abstract
OBJECTIVE There are no previous studies analyzing the prognostic predictive value of adding the tumor factor (i.e., Tumor Burden (TB) score) to the Controlling Nutritional Status (CONUT) score for patients with hepatocellular carcinoma (HCC). This study aimed to investigate the value of the CONUT plus TB (CONUT-TB) score as a prognostic predictor in patients with HCC undergoing liver resection. METHODS Between 2015 and 2018, 96 consecutive patients with HCC underwent liver resection at our institution. Patients undergoing repeated liver resection and combined resection of a metastatic lesion were excluded. Patients were divided into 2 groups according to their CONUT-TB scores according to a cutoff value. Clinicopathologic prognostic factors for survival were analyzed using a database containing the medical records. RESULTS The optimal cutoff value of the CONUT-TB score determined by using a minimum p value approach was 13 points. Among the 81 patients included in the analytic cohort, 71 patients had low (<13) and 10 patients had high (>13) CONUT-TB scores. The overall 3-year survival rate of patients following liver resection for HCC in the high-CONUT-TB group was significantly worse than that of patients in the low-CONUT-TB group (62.5 vs. 89.3%, p = 0.003). Multivariate analysis indicated that a high CONUT-TB score was independently associated with overall survival after liver resection (p = 0.010). CONCLUSION The CONUT-TB score is a valuable predictor of survival in patients with HCC after liver resection.

Abstract
We present the design and laboratory evaluation of a cryogenic continuously rotating half-wave plate (CHWP) for the POLARBEAR-2b (PB-2b) cosmic microwave background receiver, the second installment of the Simons Array. PB-2b will observe at 5200 m elevation in the Atacama Desert of Chile in two frequency bands centered at 90 GHz and 150 GHz. In order to suppress atmospheric 1/f noise and mitigate systematic effects that arise when differencing orthogonal detectors, PB-2b modulates linear sky polarization using a CHWP rotating at 2 Hz. The CHWP has a 440 mm clear aperture diameter and is cooled to ≈50 K in the PB-2b receiver cryostat. It consists of a low-friction superconducting magnetic bearing and a low-torque synchronous electromagnetic motor, which together dissipate <2 W. During cooldown, a grip-and-release mechanism centers the rotor to <0.5 mm, and during continuous rotation, an incremental optical encoder measures the rotor angle with a noise level of 0.1 μrad/Hz. We discuss the experimental requirements for the PB-2b CHWP, the designs of its various subsystems, and the results of its evaluation in the laboratory. The presented CHWP has been deployed to Chile and is expected to see first light on PB-2b in 2020 or 2021.

Abstract
Background A Killian–Jamieson diverticulum is a rare pharyngoesophageal diverticulum that is radically treated by diverticulectomy. However, there is no consensus on whether cricopharyngeal myotomy is necessary, and the optimal surgical methods that prevent postoperative complications such as leakage are undetermined. Case presentation A 49-year-old man was referred to our hospital with oropharyngeal dysphagia while eating. The patient was preoperatively diagnosed with a Killian–Jamieson diverticulum based on radiographic and clinical findings and underwent a transcervical diverticulectomy. The recurrent laryngeal nerves were preserved using an intraoperative nerve monitoring system, and the diverticulum was identified without difficulty. A partial cricopharyngeal myotomy was performed to expose the base of the diverticulum. The diverticulum was transected transversally using a linear stapler under the guidance of intraoperative upper intestinal endoscopy. A thyroid gland flap supplied by the superior thyroid artery was harvested and placed overlapping the area of the partial cricopharyngeal myotomy. Due to the proximity of the recurrent laryngeal nerve course to the diverticulum stump, the staple line was not buried with sutures. The thyroid gland flap with its rich vascular supply was fixed to completely cover the staple line on the cut surface of the thyroid gland. The postoperative course was uneventful, without vocal cord paralysis. The patient was discharged on postoperative day 8. He developed no clinical signs suggesting leakage, recurrence, or adverse events. Conclusion Killian–Jamieson diverticulectomy using a thyroid gland flap and partial cricopharyngeal myotomy is a valid treatment option that may prevent complications and recurrence. Precise evaluation of the diverticulum using an intraoperative nerve monitoring system is crucial for the repair.

Abstract
AIM Robotic surgery using the da Vinci system has markedly increased worldwide. However, robotic inguinal hernia repair remains unpopular outside the United States. We introduced and evaluated a robotic transabdominal preperitoneal repair (R-TAPP) technique for inguinal hernia in our hospital. METHODS First, we designed a task protocol according to the surgical results of 388 laparoscopic TAPP (L-TAPP) procedures performed during the 4 years prior to introducing R-TAPP. Our task protocol included several time limitations during a step-wise procedure: creating the peritoneal flap (<60 minutes), mesh placement with fixation (<30 minutes), and peritoneal suture closure (<30 minutes) under experienced supervision. We investigated the preliminary clinical results of R-TAPP performed by a single operator between December 2018 and January 2020. RESULTS We identified 27 lesions in 20 patients (unilateral in 13 and bilateral in seven). According to the Japan Hernia Society Classification, our cohort included eight type I, five type II, and seven bilateral hernias (nine type I, four type II, and one type IV). The median operation time was 124 minutes (range, 81-164 minutes), and the median console operation time was 85 minutes (range, 50-132). The median time required for the peritoneal incision was 30 minutes (range, 18-54 minutes), that for mesh placement (including tucking) was 13 minutes (range, 7-27 minutes), and that for peritoneal suturing was 9 minutes (range, 3-20 minutes). CONCLUSION Our preliminary results suggest that our task protocol for R-TAPP is feasible. However, refinement of our task protocol is essential for standardization.

Abstract
BACKGROUND Based on the spatial relationship of an aberrant right hepatic duct (ARHD) with the cystic duct and gallbladder neck, we propose a practical classification to evaluate the specific form predisposing to injury in laparoscopic cholecystectomy (LC). METHODS We retrospectively investigated the preoperative images (mostly magnetic resonance cholangiopancreatography) and clinical outcomes of 721 consecutive patients who underwent LC at our institute from 2015 to 2018. We defined the high-risk ARHD as follows: Type A: communicating with the cystic duct and Type B: running along the gallbladder neck or adjacent to the infundibulum (the minimal distance from the ARHD < 5 mm), regardless of the confluence pattern in the biliary tree. Other ARHDs were considered to be of low risk. RESULTS A high-risk ARHD was identified in 16 cases (2.2%): four (0.6%) with Type A anatomy and 12 (1.7%) with Type B. The remaining ARHD cases (n = 34, 4.7%) were categorized as low risk. There were no significant differences in the operative outcomes (operative time, blood loss, hospital stay) between the high- and low- risk groups. Subtotal cholecystectomy was applied in four cases (25%) in the high-risk group, a significantly higher percentage than the low-risk group (n = 1, 2.9%). In all patients with high-risk ARHD, LC was completed safely without bile duct injury or conversion to laparotomy. CONCLUSIONS Our simple classification of high-risk ARHD can highlight the variants located close to the dissecting site to achieve a critical view of safety and may contribute to avoiding inadvertent damage of an ARHD in LC.

Abstract
Using only cosmic microwave background polarization data from the polarbear experiment, we measure B-mode polarization delensing on subdegree scales at more than 5σ significance. We achieve a 14% B-mode power variance reduction, the highest to date for internal delensing, and improve this result to 22% by applying for the first time an iterative maximum a posteriori delensing method. Our analysis demonstrates the capability of internal delensing as a means of improving constraints on inflationary models, paving the way for the optimal analysis of next-generation primordial B-mode experiments.

Abstract
INTRODUCTION The primary concern with laparoscopic intraoperative peritoneal lavage (IOPL) for generalized peritonitis relates to the difficulty and uncertainty in ensuring adequate washout of contaminated fluid. Here, we describe a new method of laparoscopy-assisted IOPL. METHODS We performed emergency surgery in 10 patients with generalized peritonitis necessitating IOPL. A small wound retractor was inserted into the abdominal cavity through an incision and elevated to raise the abdominal wall. More than 3-L saline was injected via the retractor at one time. The abdomen was manually shaken by pressure from outside the body. Contaminated fluid was removed with a long suction device through the retractor. This procedure was repeated until the fluid was confirmed to be transparent by laparoscopy, and then drains were placed. RESULTS Median lavage time was 23.5 minutes (range, 15-34 minutes), and volume of lavage fluid was 19 L (range, 10-20 L). Median time to resumption of fluid intake was 3 days (range, 1-12 days), time to food intake was 6 days (range, 3-14 days), and time to first bowel movement was 5 days (range, 3-10 days). Median duration of antibiotic use was 8.5 days (range, 5-15 days). Complications were one case of antibiotic-induced rash, two cases of paralytic ileus, and one case of pelvic abscess. All patients recovered well without additional surgical intervention. CONCLUSIONS This new approach to laparoscopy-assisted IOPL was feasible for these patients with generalized peritonitis. This procedure enabled corpus lavage to be performed in a similarly short time to open surgery but with less invasiveness. Further research is needed to confirm indications and long-term outcomes.

Abstract
The incidence of secondary perineal hernia (SPH) has increased since the introduction of extralevator abdominoperineal resection and laparoscopic abdominoperineal resection. Currently, laparoscopic mesh repair is the usual procedure. Here, we demonstrate a repair of SPH without mesh that uses the mobilized cecum to cover the pelvic hernial orifice. An 83-year-old man complained of discomfort when sitting for long periods. He was status post laparoscopic abdominoperineal resection and was diagnosed with SPH. Hernia repair was performed. After transperitoneal adhesiolysis in the inferior pelvis, the right colon was laparoscopically mobilized, and the pelvic orifice was covered by suturing the cecum to the pelvic brim. The perineal skin was managed with negative pressure wound therapy. The postoperative course was uneventful. There has been no sign of recurrent herniation for 12 months. This method of SPH repair is simple to perform and avoids mesh-related complications.

Abstract
A search for the rare decay K_{L}→π^{0}νν[over ¯] was performed. With the data collected in 2015, corresponding to 2.2×10^{19} protons on target, a single event sensitivity of (1.30±0.01_{stat}±0.14_{syst})×10^{-9} was achieved and no candidate events were observed. We set an upper limit of 3.0×10^{-9} for the branching fraction of K_{L}→π^{0}νν[over ¯] at the 90% confidence level (C.L.), which improved the previous limit by almost an order of magnitude. An upper limit for K_{L}→π^{0}X^{0} was also set as 2.4×10^{-9} at the 90% C.L., where X^{0} is an invisible boson with a mass of 135 MeV/c^{2}.

Abstract
INTRODUCTION Laparoscopic subtotal cholecystectomy (LSC) has been recognized as an alternative to conversion to laparotomy for severe cholecystitis. However, it may be associated with an increased risk of recurrent stones in the gallbladder remnant. The objective of this study was to evaluate the safety and feasibility of the complete removal of the gallbladder cavity in LSC for severe cholecystitis using the cystic duct orifice suturing (CDOS) technique. METHODS In a consecutive series of 412 laparoscopic cholecystectomies that were performed from January 2015 to June 2017, 12 patients who underwent LSC with CDOS were enrolled in this retrospective study. In this procedure, Hartmann's pouch was carefully identified, and the infundibulum-cystic duct junction was transected while the posterior wall adherent to Calot's triangle was left behind. The clinical records, including the operative records and outcomes, were analyzed. RESULTS The median operating time and blood loss were 158 min and 20 mL, respectively. In all cases, LSC with CDOS was completed without conversion to open surgery. No injuries to the bile duct or vessels were experienced. The median postoperative hospital stay was 6 days. Postoperative complications occurred in two patients (bile leakage, n = 1: common bile duct stones, n = 1) and were successfully treated by endoscopic management. A gallbladder remnant was not delineated by postoperative imaging in any of the cases. CONCLUSION These results suggest that LSC with CDOS is a promising approach that can avoid dissection of Calot's triangle and achieve the complete removal of the gallbladder cavity in patients with severe cholecystitis.

Abstract
SummaryIn 52 men and 33 women, the total, adhesive and nonadhesive platelet counts, onestage prothrombin time, euglobulinlysis time, and plasma nonesterified fatty acid were measured before and after an intravenous injection with 0.1 μg/kg of adrenaline or 1-noradrenaline. Three hours before the injection, placebo, 30 mg of phenoxybenzamine, 300 mg of pronethalol, 100 mg of nialamide or 100 mg of pyridinolcarbamate was administered orally under the double blind technique. Five minutes after the injection with adrenaline in 15 cases pretreated with placebo, a decrease in adhesive platelet count, and a shortening of one-stage prothrombin time and euglobulin lysis time were observed with statistical significance (P ˂ 0.01 ∼ 0.05). These changes were not observed in 15 cases injected with saline or noradrenaline. The changes were not observed in 10 cases pretreated with pronethalol, but were observed in 10 cases pretreated with phenoxybenzamine. So the effect of adrenaline may be due to stimulation of ß-adrenergic receptor sites. Meanwhile, the decrease in adhesive platelet count and the enhancement of blood coagulability were prevented by nialamide and pyridinolcarbamate, while the enhancement of fibrinolysis was not. The preventive effect of nialamide was less than that of pyridinolcarbamate. Phenoxybenzamine and nialamide prevented an increase in systolic blood pressure induced by adrenaline, and pronethalol prevented tachycardia by adrenaline, while pyridinolcarbamate did not affect these changes. Changes in plasma nonesterified fatty acid showed no relationship to the above hematological changes.
