Current status of endoscopic ultrasound in the diagnosis of intraductal papillary mucinous neoplasms.

The new Kyoto guidelines for the management of intraductal papillary mucinous neoplasm (IPMN) provide evidence-based recommendations for the diagnosis and treatment of IPMN. Endoscopic ultrasonography (EUS) is a diagnostic modality with a high spatial resolution that allows detailed observation and obtaining cyst fluid or tissue samples via EUS-guided fine needle aspiration (EUS-FNA). Currently, EUS is an indispensable examination method for the diagnosis of pancreatic diseases. On the other hand, there have been concerns that EUS imaging tends to be highly operator-dependent, and may lack objectivity. Previous guidelines have assigned EUS as an option for patients with worrisome features. However, recent reports indicate that the sensitivity of EUS for the diagnosis of mural nodules (MNs) is more than 90%, comparable or superior to that of contrast-enhanced computed tomography or magnetic resonance cholangiopancreatography. The specific advantages of EUS in the diagnosis of IPMN are: (1) high spatial resolution imaging for the diagnosis of MNs, (2) contrast-enhanced EUS for differentiation of intra-cystic MNs from mucous clots, and (3) pathological diagnosis using EUS-FNA and differential diagnosis of a pancreatic cystic tumor by cystic fluid analysis. In order to utilize EUS in the diagnosis of IPMN, endoscopists are required to have the skills to provide sufficiently objective imaging findings.

Intra-Articular Corrective Osteotomy for Distal Radial Intra-Articular Malunion Using Patient-Matched Instruments: A Prospective, Multicenter, Open-Label, Single-Arm Trial.

Background: Corrective osteotomy for intra-articular malunion is a challenging procedure. However, recent advancements, including patient-matched instruments created on the basis of preoperative computer simulation, enable accurate intra-articular correction. We hypothesized that intra-articular corrective osteotomy using patient-matched instruments for the treatment of distal radial intra-articular malunion would reduce intra-articular deformity and restore wrist function at 12 months of follow-up. Methods: This prospective study included 12 patients with distal radial intra-articular malunion who underwent intra-articular corrective osteotomy external to the joint using patient-matched instruments. The primary end point was the maximum step-off on the articular surface of the distal radius, measured with use of computed tomography (CT), with an expected postoperative value of ≤1.5 mm. The secondary end points included the gap of the articular surface; range of motion; grip strength; pain evaluated using a visual analog scale (VAS); patient satisfaction; Disabilities of the Arm, Shoulder and Hand (DASH) score; and Patient-Rated Wrist Evaluation (PRWE) score. A mean postoperative step-off of ≤1.5 mm for the primary end point was assessed with use of the 1-sample t test. The secondary end points were assessed with use of the Dunnett multiple comparison test. Results: The average step-off significantly improved from 3.75 ± 1.04 mm preoperatively to 0.51 ± 0.40 mm at the 52-week postoperative follow-up and was maintained within 1.5 mm. The average wrist and forearm range of motion, VAS score, grip strength, DASH score, and PRWE score significantly improved. Eleven patients were either very satisfied or satisfied with their outcomes. Conclusions: The use of patient-matched instruments could contribute to improving postoperative outcomes of intra-articular corrective osteotomy procedures involving the distal radius. Level of Evidence: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

A case of inherited glycosylphosphatidylinositol deficiency caused by PGAP3 variant with uniparental isodisomy on chromosome 17.

BACKGROUND: Inherited glycosylphosphatidylinositol (GPI) deficiency is an autosomal recessive disease and a set of syndromes caused by different genes involved in the biosynthesis of phosphatidylinositol characterized by severe cognitive disability, elevated serum alkaline phosphatase (ALP) levels, and distinct facial features. This report presents a patient with inherited GPI deficiency caused by a homozygous frameshift variant of PGAP3 due to uniparental isodisomy (UPiD) on chromosome 17. METHOD: Clinical characteristics of the patient were collected. Microarray analysis followed by adaptive sampling sequencing targeting chromosome 17 was used for the identification of variants. Sanger sequencing was used to confirm the variant in the target region. RESULTS: The patient was born at 38 weeks of gestation with a birthweight of 3893 g. He had a distinctive facial appearance with hypertelorism, wide nasal bridge, and cleft soft palate. Postnatal head magnetic resonance imaging revealed a Blake's pouch cyst. The serum ALP level was 940 IU/L at birth and increased to 1781 IU/L at 28 days of age. Microarray analysis revealed region of homozygosity in nearly the entire region of chromosome 17, leading to the diagnosis of UPiD. Adaptive sampling sequencing targeting chromosome 17 confirmed the homozygous variant NM_033419:c.778dupG (p.Val260Glyfs*14) in the PGAP3 gene, resulting in a diagnosis of inherited GPI deficiency. CONCLUSION: This is the first report of inherited GPI deficiency caused by UPiD. Inherited GPI deficiency must be considered in patients with unexplained hyperphosphatasemia.

[Questionnaire Survey on Early-Stage Hepatocellular Carcinoma in Patients and Physicians].

We conducted an online questionnaire survey to investigate changes in well-being and anxiety in patients with hepatocellular carcinoma requiring repeated locoregional therapy(hepatectomy/ablation)and the differences between patients' and treating physicians' perceptions of what is important to patients when selecting treatment. Between December 2022 and January 2023, we collected responses from 162 patients and 115 physicians in Japan. Results showed no clinically significant changes in well-being over time. Patients experiencing recurrences and repeated locoregional therapy reported increased anxiety regarding"effectiveness of treatment"and"how to handle the disease."As"factors that patients consider important when receiving locoregional therapy,"many patients and physicians selected suppression of recurrence, prolonged survival, and safety; however, patients placed more importance on"reducing the number of locoregional therapies"as they repeatedly experienced recurrence and therapy. Regarding"information that patients consider important when selecting adjuvant therapy,""effectiveness of treatment"and"adverse effects of treatment"were important to both patients and physicians, while"maintaining a normal daily life"was more important in patients and"length of treatment"was more important in physicians. In conclusion, some factors are perceived by both physicians and patients as important when selecting treatment, but there is a gap in perception for other factors. Physicians and patients should discuss their opinions on what is important in treatment before deciding on a treatment strategy.

Adverse clinical events after percutaneous coronary intervention in very elderly patients with acute coronary syndrome.

The number of very elderly patients with acute coronary syndrome (ACS) is increasing. Therefore, owing to the need for evidence-based treatment decisions in this population, this study aimed to examine the clinical outcomes during 1 year after percutaneous coronary intervention (PCI) in very elderly patients with ACS. This prospective multicenter observational study comprised 1337 patients with ACS treated with PCI, classified into the following four groups according to age: under 60, <60 years; sexagenarian, ≥60 and <69 years; septuagenarian, ≥70 and <80 years; and very elderly, ≥80 years. The primary endpoint was a composite of the first occurrence of all-cause death, nonfatal myocardial infarction, nonfatal stroke, and bleeding within 1 year after PCI. We used the sexagenarian group as a reference and compared outcomes with those of the other groups. The incidence of the primary endpoint was significantly higher in the very elderly group than in the sexagenarian group (36 [12.7%] vs. 24 [6.9%], respectively; hazard ratio, 1.94; 95% confidence interval: 1.16-3.26; p = 0.012). The higher incidence of the primary endpoint was primarily driven by a higher incidence of all-cause death. When the multivariable analysis was used to adjust for patient characteristics and comorbidities, no difference was observed in the primary endpoint between the very elderly and sexagenarian groups (p = 0.96). The incidence of adverse events after PCI, particularly all-cause death, in very elderly patients with ACS was high. However, if several confounders are adjusted, comparable outcomes may be expected within 1 year after PCI among this population.

Female social dynamics as viewed from grooming networks in the Central Himalayan Langur (Semnopithecus schistaceus).

Enhanced survival and reproduction are associated with an individual's direct and indirect social connections with members of a group. Yet, the role of these connections is little known in a vast range of primate species. We studied female Central Himalayan Langur (CHL) to investigate the link between four specific attributes (dominance rank, age, genetic relatedness, and the presence of females carrying infants) and a female's direct and indirect social relationships. By analyzing grooming networks, we revealed different behavioral strategies: high-ranking females form relationships with many females (high degree), whereas females with dependent infants have strong relationships (high strength and eigenvector). Subadult females are important individuals that hold the social network together (high betweenness), while an immigrant female strategy is to integrate herself into the group by forming strong bonds with females who themselves have strong bonds (high eigenvector). Our study sheds light on how behavioral strategies shape female CHL grooming networks, which may help them to secure fitness and survival advantages.

Two Cases of Cardiovascular Adverse Events Following Subcutaneous Vosoritide Injection in Early Infancy.

Achondroplasia, characterized by short stature and skeletal abnormalities, is caused by a gain-of-function variant in the fibroblast growth factor receptor 3 gene. Vosoritide, a C-type natriuretic peptide analog, is an emerging treatment for achondroplasia that functions by promoting endochondral ossification. Vosoritide was approved for the treatment of achondroplasia in Europe and the United States in 2021, and in Japan, the following year. However, vosoritide is associated with a risk of hypotension and vomiting after subcutaneous injection due to its vasodilating effect. Herein, we present two cases of cardiovascular adverse events in infants following vosoritide injection. Case 1 involved a one-month-old female infant with achondroplasia who received the first subcutaneous injection of vosoritide 30 minutes after her last formula intake. Following injection, she developed transient symptomatic hypotension accompanied by vomiting. Although established guidelines recommend that injections be administered after approximately 30 minutes (Europe/Japan) or within one hour (USA) following the last feeding, an extended interval of 1.5 to two hours was required to prevent hypotension-associated vomiting. Case 2 involved a three-month-old female infant with achondroplasia. The first subcutaneous vosoritide injection was administered four hours after the last formula intake, and she subsequently developed prolonged compensated shock with marked tachycardia requiring intervention, including repetitive bolus saline injection. These cases indicate the need to monitor patients for cardiovascular adverse events following subcutaneous injection of vosoritide in early infancy.

Development of an Organic Emitter Exhibiting Reverse Intersystem Crossing Faster than Intersystem Crossing.

In thermally activated delayed fluorescence (TADF)-based organic light-emitting diodes (OLEDs), acceleration of reverse intersystem crossing (RISC) and suppression of intersystem crossing (ISC) are demanded to shorten a lifetime of triplet excitons. As a system realizing RISC faster than ISC, inverted singlet-triplet excited states (iST) with a negative energy difference (ΔEST) between the lowest excited singlet and the lowest triplet states have been gathering much attention recently. Here, we have focused on an asymmetric hexa-azaphenalene (A6AP) core to obtain a new insight into iST. Based on A6AP, we have newly designed A6AP-Cz with the calculated ΔEST of -44 meV. The experimental studies of a synthesized A6AP-Cz revealed that the lifetime of delayed fluorescence (τDF) was only 54 ns, which was the shortest among all organic materials. The rate constant of RISC (kRISC=1.9×107 s-1) was greater than that of ISC (kISC=1.0×107 s-1). The negative ΔEST of A6AP-Cz was experimentally confirmed from 1) the kRISC and kISC (-45 meV) and 2) the temperature-dependent τDF. 3) The onsets of fluorescence and phosphorescence spectra at 77 K also supported the evidence of negative ΔEST (-73 meV). This study demonstrated the potential of A6AP as an iST core for the first time.

Determinants of One-Year Outcome After Successful Percutaneous Coronary Intervention for Chronic Total Occlusion; Insight from Japanese CTO-PCI Expert Registry.

Although outcomes have improved with new-generation drug-eluting stents, few reports have analyzed the risk factors associated with chronic outcomes of chronic total occlusion (CTO)-percutaneous coronary intervention (PCI). This study aimed to investigate the independent risk factors for target lesion revascularization (TLR) and major adverse cardiac and cerebrovascular events (MACCEs) after CTO-PCI using Japanese multicenter data. A total of 3,666 patients, who underwent CTO-PCI and completed a 1-year follow-up, registered at the Japanese CTO-PCI Expert Registry from 2014 to 2019, were examined. The primary outcome was defined as TLR, and the secondary outcome was MACCEs at the 1-year follow-up. TLRs and MACCEs occurred in 175 (4.8%) and 524 (14.3%) patients, respectively. Multivariate logistic regression analysis demonstrated that in-stent occlusion (ISO) (odds ratio [OR] 2.604, 95% confidence interval [CI] 1.695 to 4.001), hemodialysis (OR 1.784, 95% CI 1.062 to 2.997), diabetes mellitus with insulin use (OR 1.741, 95% CI 1.060 to 2.861), moderate-to-severe calcification (OR 1.726, 95% CI 1.197 to 2.487), and the right coronary artery as the target vessel (OR 1.468, 95% CI 1.018 to 2.117) were significantly associated with TLR. Hemodialysis (OR 2.214, 95% CI 1.574 to 3.113), ISO (OR 1.499, 95% CI 1.127 to 1.993), arteriosclerosis obliterans (OR 1.414, 95% CI 1.074 to 1.863), and multivessel disease (OR 1.356, 95% CI 1.117 to 1.647) were significantly associated with MACCEs. One-year outcomes of new-generation drug-eluting stents for CTO-PCI were favorable, and ISO as a lesion factor and hemodialysis as a patient factor were strongly associated with TLR and MACCEs, respectively.

Three-dimensional corrective osteotomy for cubitus varus deformity using patient-matched instruments.

Background: Various methods of two or three-dimensional (3D) corrective osteotomy for cubitus varus deformity have been reported. However, whether 3D correction of cubitus varus deformity is necessary is controversial because of technical difficulties and surgical complications. This study introduced 3D simulations and printing technology for corrective osteotomy against cubitus varus deformities. Moreover, recent studies on the application of these technologies were reviewed. Methods: The amount of 3D deformity was calculated based on the difference in 3D shape between the affected side and the contralateral normal side. Patient-matched instruments were created to perform the actual surgery as simulated. Further, a 3D corrective osteotomy was performed using patient-matched instruments for cubitus varus deformity in pediatric and adolescent patients. The humerus-elbow-wrist angle, tilting angle, and elbow ranges of motion were evaluated. Results: Humerus-elbow-wrist angle and tilting angle were corrected from -21° to 14° and from 30° to 43°, respectively, in the pediatric patient and from -18° to 10° and from 20° to 40°, respectively, in the adolescent patient. The elbow flexion and extension angles changed from 130° to 140° and from 20° to 10°, respectively, in the pediatric patient and from 120° to 130° and from 15° to 0°, respectively, in the adolescent patient. Conclusion: The 3D computer simulations and the use of patient-matched instruments for cubitus varus deformity are reliable and can facilitate an accurate and safe correction. These technologies can simplify the complexity of 3D surgical procedures and contribute to the standardization of treatment for cubitus varus deformity.

Contributions of endoscopic ultrasonography-guided tissue acquisition (EUS-TA) to the diagnostics of biliary stricture and gallbladder lesions.

Endoscopic ultrasonography (EUS) provides high spatial resolution and more detailed images than other diagnostic modalities. Furthermore, EUS-guided tissue acquisition (EUS-TA), such as EUS-guided fine needle aspiration or biopsy (EUS-FNA/FNB), is an indispensable tool in pancreaticobiliary disease diagnostics, supporting a conclusive pathological diagnosis. In this review, we evaluate the current status and the usefulness of EUS-TA for the diagnostics of the following biliary tract diseases: (A) biliary stricture diagnostics, (B) biliary tract cancer (BTC) itself, and (C) staging of advanced BTC. Previous reports have shown that EUS-FNA for biliary lesions is a safe procedure that is useful in differentiating biliary cancer from benign lesions and in the staging of BTC. On the other hand, the diagnostic performance of EUS-TA for bile duct lesions is reported to be similar to that of transpapillary biopsy. Overall, EUS-TA for biliary lesions may be a safe and effective method, but it should be performed with an understanding of the risk of serious adverse events such as bile leakage and peritoneal dissemination of cancer. It is recommended for distal biliary stricture lesions for which endoscopic retrograde cholangiopancreatography cannot confirm the diagnosis or gallbladder lesions if they do not require the needle to pass through the biliary lumen.

Cubitus varus deformity following paediatric supracondylar humeral fracture remodelling predominantly in the sagittal direction: A three-dimensional analysis of eighty-six cases.

PURPOSE: Three-dimensional (3D) capacity for remodelling in cubitus varus deformity (CVD) after paediatric supracondylar humeral fractures (PSHFs) remains unelucidated. This study investigated remodelling patterns after PSHFs by examining 3D deformity distribution over time after injury. METHODS: Computed tomography (CT) data of 86 patients with CVD after PSHFs were analysed. The 3D deformity angles in the sagittal, coronal, and axial directions were assessed and correlated with the duration between the age at injury and CT evaluation. For the subgroup analysis, we performed the same correlation analysis in a younger (< 8 years old) and an older group (≥ 8 years old); we categorized the duration into early (< 2 years), middle (≥ 2 to < 5 years), and late periods (≥ 5 years) and compared the deformity angles of each direction among the three groups. RESULTS: Sagittal deformity showed a moderate correlation with the duration of deformity (r = -0.54; P < 0.001), while coronal and axial deformities showed a negligible correlation. Sagittal deformity showed moderate correlations with the duration in the younger group (r = -0.62; P < 0.001) and weak correlations in the older group (r = -0.37; P = 0.091). In the sagittal direction, the deformity angle in the early period was significantly larger than those in the mid and late periods (P < 0.001). However, there were no significant differences among the three groups in the coronal and axial directions. CONCLUSION: Sagittal deformities in CVDs are capable of remodelling, especially in the early period and at a younger age, whereas coronal and axial deformities are less likely to undergo remodelling.

Adverse Event Profile of Atezolizumab, Bevacizumab, Carboplatin, and Paclitaxel Combination Therapy Based on JADER.

BACKGROUND/AIM: There have been advances in the development of immune checkpoint inhibitors for monotherapy and combination therapy with other anticancer agents in recent years. The combination of bevacizumab, carboplatin, and paclitaxel with atezolizumab, an anti-programmed death ligand 1 antibody (ABCP therapy), has been reported to be effective for treating non-small cell lung cancer. However, reports on its adverse events are limited. In this study, a survey and disproportionality analysis based on the Japanese Adverse Drug Event Report (JADER) database was conducted to elucidate the adverse event profile of ABCP therapy. MATERIALS AND METHODS: The reporting odds ratio (ROR) and information component were used as indicators for the disproportionality analysis. The ROR was also used to assess the changes in the reporting intensity with combination therapy, and the mutual exclusivity of the 95% confidence interval between the compared groups was considered. RESULTS: The reported adverse events of ABCP therapy mirrored those of the individual drugs that constituted it. ABCP therapy enhanced the reporting intensity of adverse events related to leukocytes and the skin, while decreased those related to interstitial lung disease and hepatic function abnormality as immune-related adverse events caused by atezolizumab, and gastrointestinal perforation caused by bevacizumab. CONCLUSION: Our analysis of data from the JADER database has revealed the adverse event profile of ABCP therapy. Our findings emphasize the importance of effectively managing febrile neutropenia and skin-related adverse events in ABCP therapy.

Retrograde Coronary Chronic Total Occlusion Intervention (JR-CTO) Score: From the Japanese CTO-PCI Expert Registry.

BACKGROUND: Despite the effectiveness of the retrograde approach for chronic total occlusion (CTO) lesions, there are no standardized tools to predict the success of retrograde percutaneous coronary intervention (PCI). OBJECTIVES: The aim of this study was to develop a prediction tool to identify CTO lesions that will achieve successful retrograde PCI. METHODS: This study evaluated data from 2,374 patients who underwent primary retrograde CTO-PCI and were enrolled in the Japanese CTO-PCI Expert Registry between January 2016 and December 2022 (NCT01889459). All observations were randomly assigned to the derivation and validation cohorts at a 2:1 ratio. The prediction score for guidewire failure in retrograde CTO-PCI was determined by assigning 1 point for each factor and summing all accrued points. RESULTS: The JR-CTO score (moderate-severe calcification, tortuosity, Werner collateral connection grade ≤1, and nonseptal collateral channel) demonstrated a C-statistic for guidewire failure of 0.72 (95% CI: 0.67-0.76) and 0.71 (95% CI: 0.64-0.77) in the derivation and validation cohorts, respectively. Patients with lower scores had higher guidewire and technical success rates and decreased guidewire crossing time and procedural time (P < 0.01). CONCLUSIONS: The JR-CTO (Japanese Retrograde Chronic Total Occlusion) score, a simple 4-item score that predicts successful guidewire crossing in patients undergoing retrograde CTO-PCI, has the potential to support clinical decision-making for the retrograde approach.

Burosumab vs conventional therapy in children with X-linked hypophosphatemia: results of the open-label, phase 3 extension period.

In a randomized, open-label phase 3 study of 61 children aged 1-12 years old with X-linked hypophosphatemia (XLH) previously treated with conventional therapy, changing to burosumab every 2 weeks (Q2W) for 64 weeks improved the phosphate metabolism, radiographic rickets, and growth compared with conventional therapy. In this open-label extension period (weeks 64-88), 21 children continued burosumab Q2W at the previous dose or crossed over from conventional therapy to burosumab starting at 0.8 mg/kg Q2W with continued clinical radiographic assessments through week 88. Efficacy endpoints and safety observations were summarized descriptively for both groups (burosumab continuation, n = 6; crossover, n = 15). At week 88 compared with baseline, improvements in the following outcomes were observed in the burosumab continuation and crossover groups, respectively: mean (SD) RGI-C rickets total score (primary outcome), +2.11 (0.27) and +1.89 (0.35); mean (SD) RGI-C lower limb deformity score, +1.61 (0.91) and +0.73 (0.82); and mean (SD) height Z-score + 0.41 (0.50) and +0.08 (0.34). Phosphate metabolism normalized rapidly in the crossover group and persisted in the continuation group. Mean (SD) serum alkaline phosphatase decreased from 169% (43%) of the upper limit of normal (ULN) at baseline to 126% (51%) at week 88 in the continuation group and from 157% (33%) of the ULN at baseline to 111% (23%) at week 88 in the crossover group. During the extension period, treatment-emergent adverse events (AEs) were reported in all 6 children in the burosumab continuation group and 14/15 children in the crossover group. The AE profiles in the randomized and extension periods were similar, with no new safety signals identified. Improvements from baseline in radiographic rickets continued in the extension period among children with XLH who remained on burosumab. Children who crossed over from conventional therapy to burosumab demonstrated a rapid improvement in phosphate metabolism and improved rickets healing over the ensuing 22 weeks.

Optimal Intravascular Ultrasound-Guided Percutaneous Coronary Intervention in Patients With Multivessel Disease and Diabetes.

There is a scarcity of data on clinical outcomes after intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) in patients with multivessel disease and diabetes. The Optimal Intravascular Ultrasound Guided Complex Percutaneous Coronary Intervention study multivessel cohort was a prospective, multicenter, single-arm trial enrolling 1,021 patients who underwent multivessel PCI, including left anterior descending coronary artery using IVUS, aiming to meet the prespecified OPTIVUS criteria for optimal stent expansion. We compared the clinical outcomes between those patients with and without diabetes. The primary end point was a composite of death, myocardial infarction, stroke, or any coronary revascularization. There were 560 patients (54.8%) with diabetes and 461 patients (45.2%) without diabetes. The mean age was not different between the 2 groups (70.9 ± 9.7 vs 71.7 ± 10.4 years, p = 0.17). Patients with diabetes more often had chronic kidney disease and complex coronary artery disease, as indicated by the greater total number of stents and longer total stent length. The rate of meeting the OPTIVUS criteria was not different between the 2 groups (61.2% vs 60.7%, p = 0.83). The cumulative 1-year incidence of the primary end point was not different between the 2 groups (10.8% vs 9.8%, log-rank p = 0.65). After adjusting for confounders, the risk of diabetes relative to nondiabetes remained insignificant for the primary end point (hazard ratio 0.97, 95% confidence interval 0.65 to 1.44, p = 0.88). In conclusion, in patients who underwent multivessel IVUS-guided PCI and were managed with contemporary clinical practice, patients with diabetes had similar 1-year outcomes to patients without diabetes.

Hypotension after general anaesthesia induction using remimazolam or propofol in geriatric patients undergoing sevoflurane anaesthesia with remifentanil: a single-centre, double-blind, randomised controlled trial.

BACKGROUND: The occurrence of hypotension after induction of general anaesthesia is common in geriatric patients, and should be prevented to minimise perioperative complications. Compared with propofol, remimazolam potentially has a lower incidence of hypotension. This study aimed to compare the incidence of hypotension after general anaesthesia induction with remimazolam or propofol in geriatric patients. METHODS: This single-centre, double-blind, randomised trial enrolled 90 patients aged ≥80 yr who received general anaesthesia for scheduled surgery. Patients were randomised to receive remimazolam (12 mg kg-1 h-1) or propofol (0.025 mg kg-1 s-1) for anaesthesia induction, with remifentanil and sevoflurane. The presence or absence of hypertension on the ward served as the stratification factor. The incidence of hypotension after the induction of general anaesthesia, defined as a noninvasive mean arterial pressure of <65 mm Hg measured every minute from initiation of drug administration to 3 min after tracheal intubation, was the primary outcome. Subgroup analysis was performed for the primary outcome using preoperative ward hypertension, clinical frailty scale, Charlson Comorbidity Index, and age. RESULTS: Three subjects were excluded before drug administration, and 87 subjects were included in the analysis. The incidence of hypotension was 72.1% (31/43) and 72.7% (32/44) with remimazolam or propofol, respectively. No statistically significant differences (adjusted odds ratio, 0.96; 95% confidence interval, 0.37-2.46; P=0.93) were observed between groups. Subgroup analysis revealed no significant differences between groups. CONCLUSIONS: Compared with propofol, remimazolam did not reduce the incidence of hypotension after general anaesthesia induction in patients aged ≥80 yr. CLINICAL TRIAL REGISTRATION: UMIN000042587.

Elderly Woman With No Autoimmune Disease With Aseptic Meningitis Caused by Celecoxib.

Nonsteroidal anti-inflammatory drug (NSAID)-induced aseptic meningitis (NIAM) is frequently reported in patients with autoimmune disease. Ibuprofen-induced NIAM is the most common case report of NIAM. We report a patient without autoimmune disease who developed NIAM following oral celecoxib administration. A literature review and survey of cases registered in the Japanese Adverse Drug Event Report (JADER) database is also provided. A 73-year-old woman with no autoimmune disease developed a headache the day after taking celecoxib, and NIAM was suspected. The headache resolved quickly following celecoxib discontinuation. Although lumbar puncture was not available in this case, bacterial or viral meningitis was negative, and NIAM could not be ruled out. This case involved an older adult patient without an autoimmune disease, with celecoxib as the causative NSAID. A literature review found numerous cases of autoimmune diseases in younger patients. To date, only one case of celecoxib-induced NIAM has been reported. Analysis of NIAM cases in JADER revealed an onset time of approximately three days. JADER analysis indicated that NIAM tended to occur immediately after administration, although the onset with cyclooxygenase-2 selective agents might be slower.
