Although the potential risks and characteristics for targeted anticancer agent- and immunotherapy-induced SCAR were not well understood, these serious adverse reactions usually result in morbidity and sequela. As a treatment guideline for this devastating condition is still unavailable, prompt withdrawal of causative drugs is believed to be a priority of patient management. In this review, we outline distinct types of SCARs caused by targeted anticancer therapies and immunotherapies. Also, we discuss the clinical course, latency, concomitant medication, tolerability of rechallenge or alternatives, tumor response, and mortality associated with these devastating conditions. Imatinib, vemurafenib, and rituximab were the top three offending medications that most commonly caused SJS/TEN, while EGFR inhibitors were the group of drugs that most frequently induced SJS/TEN. For drug rash with eosinophilia and systemic symptoms/drug-induced hypersensitivity syndrome and acute generalized exanthematous pustulosis, imatinib was also the most common offending drug. Additionally, we delineated 10 SCAR cases related to innovative immunotherapies, including PD1 and CTLA4 inhibitors. There was a wide range of latency periods: 5.5–91 days (median). Only eight of 16 reported patients with SCAR showed clinical responses. Targeted anticancer drugs and immunotherapies can lead to lethal SCAR (14 deceased patients were identified as suffering from SJS/TEN). The mortality rate of TEN was high: up to 52.4%. The information compiled herein will serve as a solid foundation to formulate ideas for early recognition of SCAR and to discontinue offending drugs for better management.

This study applied multiscale entropy analysis to investigate the correlation between the complexity of intracranial pressure waveform and outcome after traumatic brain injury. Intracranial pressure and arterial blood pressure waveforms were low-pass filtered to remove the respiratory and pulse components and then processed using a multiscale entropy algorithm to produce a complexity index. We identified significant differences across groups classified by the Glasgow Outcome Scale in intracranial pressure, pressure-reactivity index and complexity index of intracranial pressure (P < 0.0001; P = 0.001; P < 0.0001, respectively). Outcome was dichotomized as survival/death and also as favourable/unfavourable. The complexity index of intracranial pressure achieved the strongest statistical significance (F = 28.7; P < 0.0001 and F = 17.21; P < 0.0001, respectively) and was identified as a significant independent predictor of mortality and favourable outcome in a multivariable logistic regression model (P < 0.0001). The results of this study suggest that complexity of intracranial pressure assessed by multiscale entropy was significantly associated with outcome in patients with brain injury.

Objectives: To find a noninvasive method to detect coarctation of the aorta (CoA) in the presence of a patent ductus arteriosus (PDA) in neonates. Study Design: From 1994 to 1998, 36 neonates with CoA and PDA confirmed by surgery or cardiac catheterization were studied; another 19 neonates with isolated PDA served as control patients. The prospective study was conducted from 2001 to 2002 on 162 neonates. Results: Among the 36 neonates in the CoA group, 14 patients (39%) had blood pressure discrepancy, 26 patients (72%) had a visualized posterior shelf by echocardiogram, and the ratio of isthmus/descending aorta diameters (I/D ratio) was below 0.64 in 32 patients (89%). None of the control patients had these features. A diagnostic approach was subsequently proposed, according to which a neonate with PDA who fulfilled any of the above features was diagnosed as CoA plus PDA. In the prospective study, the sensitivity and positive predictive values of this method were both 91.7%, whereas the specificity and negative predictive values were both 99.3%. Conclusions: Echocardiographic measurements of I/D ratio along with the delineation of posterior shelf and a BP discrepancy can satisfactorily identify CoA in the presence of PDA in neonates.

BACKGROUND: Abnormally elevated alanine aminotransferase (ALT) of nonspecific causes is a common outpatient problem. Without considering ethnicity, several studies had suggested that it was associated with insulin resistance (IR). OBJECTIVE: To investigate whether nonspecific elevated ALT in Taiwanese population could reflect a likely underlying IR and was associated with impaired fasting glucose or type 2 diabetes mellitus (IFG/T2DM). METHODS: The health examination profiles of 1313 Taiwanese were investigated cross-sectionally. The prevalence and odds ratios (ORs) for IFG/T2DM and metabolic abnormalities in relation to elevated ALT were analyzed. RESULTS: Subjects with metabolic syndrome (MS) all had IFG/T2DM. The elevated ALT significantly correlated with MS and IFG/T2DM (i.e., 19.9-29.2% vs. 7.8% for MS, and 27.0-31.5% vs. 16.1% for IFG/T2DM). However, after excluding MS and adjustment for age and sex, the elevated ALT alone was not consistently associated with IFG/T2DM (36120 had IFG). CONCLUSIONS: In a cross-sectional analysis of Taiwanese industrial employees, elevated ALT associated with MS, but in subjects who did not meet MS criteria, elevated ALT by itself did not associate with IFG/T2DM.

Background: Twin atrioventricular (AV) nodes (TWAVNs) are common in heterotaxy syndrome., Objective: The purpose of this study was to investigate the presence and implications of TWAVNs and accessory pathways in congenital heart diseases (CHDs) with abnormal AV connections., Methods: A retrospective study of a 1980-2022 cohort with sufficient electrocardiographic (ECG) data for review was conducted., Results: We enrolled 136 patients with heterotaxy syndrome, 70 with congenitally corrected transposition of the great arteries (ccTGA) (4 with Ebstein anomaly), 47 with double-inlet ventricle (DIV), and 63 with isolated AV canal defect. TWAVNs, detected in the same ECG (18%), in separate ECGs (70.8%), or after electrophysiological study (11.2%), were present in 43.4% of heterotaxy, 10.6% of DIV, 10% of ccTGA, and 1.6% of AV canal defect cases. Accessory pathways were noted in 11.4% of ccTGA and 4.4% of heterotaxy cases, but none of the DIV and AV canal cases. Actuarial incidence of supraventricular tachycardia (SVT) by age 10 was 0.354, 0.121, 0.022, and 0 in heterotaxy, ccTGA, DIV, and AV canal, respectively. In patients with TWAVNs, the risk of SVT varies according to the rate of TWAVNs in each CHD type, with risks of 65.5%, 58.3%, and 0% for TWAVNs rates >50%, 10%-50%, and <10%, respectively. Onset age of tachycardia did not differ between those with TWAVNs and those with accessory pathways., Conclusion: In CHD with abnormal AV connections, evidence suggested a developmental hierarchy in the propensity to exhibit TWAVNs, but not for accessory pathways. The earlier cardiac developmental errors occur, the higher the likelihood of TWAVNs and the greater the chance of SVT., Competing Interests: Disclosures The authors have no conflicts to disclose., (Copyright © 2024 Heart Rhythm Society.

Background: As a drug-induced hypersensitivity syndrome, drug reaction with eosinophilia and systemic symptoms (DRESS) is potentially fatal. Most patients with DRESS recover within a few weeks; however, some patients may suffer from a prolonged disease course and develop autoimmune sequelae., Objective: We investigated the immune mechanism and therapeutic targets of patients with recalcitrant DRESS with a prolonged disease course., Methods: A total of 32 patients with recalcitrant DRESS with a prolonged treatment course ≥8 weeks, 28 patients with short-duration DRESS with a treatment course <2 weeks, and 26 healthy individuals were enrolled in the study for analysis., Results: Bulk transcriptome results demonstrated that mRNA expression levels of CCR8 and CXCR3 were significantly increased in the blood samples from patients in the acute stage of prolonged DRESS (adjusted p-values: CCR8=1.50×10-9 and CXCR3=2.60×10-4, respectively, for comparison of patients with prolonged DRESS to the healthy donor group). Serum and skin lesional concentrations of CCL1 and CXCL10, as the ligands of CCR8 and CXCR3, respectively, were significantly elevated in patients with prolonged DRESS as compared to those patients with short-duration DRESS. The results from high-parameter flow cytometry and autoantibody screening also identified significant escalations of CD8+ GNLY+CXCR3+effector memory T cells, CD8+central memory T cells, CD4+CCR8+Th2 cells, and IgG-anti-HES6 autoantibodies in patients with prolonged DRESS. Furthermore, in vitro blocking assays revealed that JAK inhibitors (mainly tofacitinib and upadacitinib) significantly decreased the release of CCL1 and CXCL10, and some patients with prolonged DRESS were successfully treated with JAK inhibitors., Conclusions: JAK inhibitors (tofacitinib and upadacitinib) were associated with decreased concentrations of CCL1 and CXCL10, suggesting that they may attenuate CCR8/CCL1- and CXCR3/CXCL10-axis-mediated memory T cell activation, which contribute to disease pathogenesis for patients with recalcitrant DRESS and a long-term treatment course., (© The Author(s) 2024.

Background: Osimertinib, a third-generation epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI), shows superior lung cancer treatment efficacy. However, osimertinib-induced severe hypersensitivity, including Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN), is frequently observed in Asian populations and hinders cancer treatment., Objective: We investigated the genetic HLA predisposition and immune pathomechanism of osimertinib-induced hypersensitivity., Methods: We enrolled 17 patients with osimertinib-induced delayed hypersensitivity (7 with severe SJS/TEN and 10 with mild maculopapular exanthema [MPE]), 98 osimertinib-tolerant subjects, and 2123 general population controls. HLA genotyping, drug-induced lymphocyte activation test (LAT), and surface plasmon resonance (SPR) assay were performed., Results: HLA-B*51:02 was present in 83.3% of osimertinib-induced SJS/TEN patients but only in 3.3% of the general population controls (P = 2.8×10 -7 , Pc=6.9×10 -6 , odds ratio [OR]=146), and 0% of osimertinib-tolerant controls (P = 6.5×10 -8 , Pc=1.6×10 -6 , OR=707). The association of HLA-B*51:01 and HLA-A*24:02 with osimertinib-induced MPE patients, rather than with osimertinib-tolerant subjects (P = 0.002, OR=15.7 for HLA-B*51:01; P = 0.003, OR=9.5 for HLA-A*24:02), was identified as a phenotype-specific association. Granulysin-the SJS/TEN-specific cytotoxic protein-was significantly higher in SJS/TEN patients' plasma (39.8±4.5 ng/ml, P<0.001) and in in vitro LAT (sensitivity=83.3%, P<0.01) compared to the tolerant controls. Patients with osimertinib-induced hypersensitivity appeared to tolerate alternative EGFR-TKIs. SPR results also confirmed that HLA-B*51:02 protein has a higher binding affinity for osimertinib and lower or no affinity for other EGFR-TKIs., Conclusions: HLA-B*51:02 frequently occurs in Asian populations and is strongly associated with osimertinib-induced SJS/TEN. Our findings suggest HLA-B*51:02 screening as a preemptive test to reduce osimertinib-induced severe hypersensitivity., (Copyright © 2024. Published by Elsevier Inc.)

Background: Tumor spread through air spaces (STAS) has been recognized as a prognostic factor for several types of lung cancers. However, information regarding its clinical significance in pulmonary lymphoepithelial carcinoma is limited. Therefore, this study investigated effects of STAS on the clinical outcomes for patients with pulmonary lymphoepithelial carcinoma., Methods: This study retrospectively reviewed 56 surgically resected pulmonary lymphoepithelial carcinomas. The study defined STAS as the presence of tumor cells within air spaces in lung parenchyma beyond the tumor edge. Artifacts were excluded. Recurrence-free survival (RFS) was analyzed using the log-rank test and Cox proportional hazards model., Results: In 18 patients (32.1%), STAS was observed and found to be associated with larger tumor size (>3 cm) (p = 0.009), higher pathologic stage (p = 0.026), and tumor necrosis (p = 0.046). Patients with STAS had a significantly lower 5-year RFS rate (p = 0.025). Multivariate analysis showed that STAS was an independent predictor of worse RFS (hazard ratio, 3.395; p = 0.038). Patients with STAS had a significantly increased risk of locoregional recurrence (p = 0.049)., Conclusions: The study findings suggest that STAS is an independent predictor of poor RFS. Based on these findings, a new three-tier grading system based on the patterns of tumor border and STAS was proposed for effective prediction of 5-year RFS in pulmonary lymphoepithelial carcinoma., Competing Interests: Disclosures The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024.

Objectives: This study aimed to identify clinical characteristics to differentiate multisystem inflammatory syndrome in children (MIS-C) and Kawasaki disease (KD) in Taiwan, an island with a delayed cluster of MIS-C and a high incidence of KD. Additionally, we studied risk factors for developing severe complications in patients with MIS-C., Methods: We conducted a retrospective, multicenter, cohort, and observational study that linked data on patients with MIS-C between May and December 2022 and patients with KD between 2019 and 2021 from 12 medical centers. Hemodynamic compromise, defined as the need for inotropic support or fluid challenge, was recorded in patients with MIS-C. We also evaluated maximal coronary Z-scores before treatment and one month after disease onset., Results: A total of 83 patients with MIS-C and 466 patients with KD were recruited. A 1:1 age and gender-matched comparison of 68 MIS-C and KD pairs showed that MIS-C patients had a lower percentage of positive BCG red halos, lower leukocyte/platelet counts, more gastrointestinal symptoms, and a higher risk of hemodynamic compromise. In Taiwan, 38.6% of MIS-C patients experienced hemodynamic compromise, with presence of conjunctivitis and elevated levels of procalcitonin (>1.62 ng/mL) identified as independent risk factors., Conclusion: We identified two independent risk factors associated with hemodynamic compromise in MIS-C patients. The comparison between matched MIS-C and KD patients highlighted significant differences in clinical presentations, like BCG red halos, which may aid in the differential diagnosis of the two disease entities, especially in regions with a high incidence rate of KD., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Formosan Medical Association.

Objective. Decades ago, neurosurgeons used electrical impedance measurements in the brain for coarse intraoperative tissue differentiation. Over time, these techniques were largely replaced by more refined imaging and electrophysiological localization. Today, advanced methods of diffusion tensor imaging (DTI) and finite element method (FEM) modeling may permit non-invasive, high-resolution intracerebral impedance prediction. However, expectations for tissue-impedance relationships and experimentally verified parameters for impedance modeling in human brains are lacking. This study seeks to address this need. Approach. We used FEM to simulate high-resolution single- and dual-electrode impedance measurements along linear electrode trajectories through (1) canonical gray and white matter tissue models, and (2) selected anatomic structures within whole-brain patient DTI-based models. We then compared intraoperative impedance measurements taken at known locations along deep brain stimulation (DBS) surgical trajectories with model predictions to evaluate model accuracy and refine model parameters. Main results. In DTI-FEM models, single- and dual-electrode configurations performed similarly. While only dual-electrode configurations were sensitive to white matter fiber orientation, other influences on impedance, such as white matter density, enabled single-electrode impedance measurements to display significant spatial variation even within purely white matter structures. We compared 308 intraoperative single-electrode impedance measurements in five DBS patients to DTI-FEM predictions at one-to-one corresponding locations. After calibration of model coefficients to these data, predicted impedances reliably estimated intraoperative measurements in all patients (R=0.784±0.116,n=5). Through this study, we derived an updated value for the slope coefficient of the DTI conductance model published by Tuch et al ,k=0.0649 S⋅smm-3 (originalk=0.844), for use specifically in humans at physiological frequencies. Significance. This is the first study to compare impedance estimates from imaging-based models of human brain tissue to experimental measurements at the same locations in vivo . Accurate, non-invasive, imaging-based impedance prediction has numerous applications in functional neurosurgery, including tissue mapping, intraoperative electrode localization, and DBS., (Creative Commons Attribution license.)

Background: With the widespread outbreak of monkeypox, it is crucial to enhance awareness and understanding of the disease, especially among high-risk individuals. This study aimed to investigate the knowledge levels of individuals seeking preexposure vaccination in Taiwan., Methods: This descriptive cross-sectional questionnaire survey was conducted online, and included a nationwide sample of high-risk adults receiving preexposure vaccination. The questionnaire comprised 30 items with six aspects and explanatory variables. A multivariate logistic regression model was used to identify the factors that influenced participants' knowledge of human monkeypox., Results: Among 2,604 participants, 97.3 % were male, 76.4 % identified as homosexual, and 24.4 % had a history of HIV infection. Approximately half of the participants displayed inadequate knowledge of human monkeypox, with weaker performance in diagnosis and treatment aspects. Using a multivariate logistic model, we found that those with a medical background or higher education level had a better understanding after adjustment for potential confounding factors. Among those with an educational level of college or below, men who had sex with men (MSM) without HIV displayed significantly lower knowledge levels (OR: 0.68; 95 % CI 0.51-0.91)., Conclusions: The existence of a knowledge gap within subgroups of MSM highlights the necessity for targeted educational interventions., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Interpreting high-throughput transcriptomic and metagenomic data from non-model microorganisms presents a challenge due to the significant number of genes with unknown functions and sequences. In this study, we applied an innovative microarray, Dehalochip, for detecting the expression of genes in various microorganisms, particularly focusing on genes involved in chloroethene degradation. Our results demonstrated that this approach can effectively identify dechlorination genes, such as 16S rRNA, tceA, bvcA, and vcrA, in Dehalococcoides mccartyi from samples of groundwater contaminated with chloroethene. Noticeably, the sensitivity and specificity of our Dehalochip are comparable to that of quantitative PCR. However, it stands out as a more viable option for in-situ applications due to its greater capacity to infer potential dechlorination genes. Consequently, we believe our dechlorination microarray offers valuable insights into the role of known microorganisms and their associated functional genes in chloroethene-contaminated environments. This contributes to a deeper understanding of the in-situ reductive dechlorination process., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

High-order topological phases of matter refer to the systems of n-dimensional bulk with the topology of m-th order, exhibiting (n-m)-dimensional boundary modes and can be characterized by topological pumping. Here, we experimentally demonstrate two types of second-order topological pumps, forming four 0-dimensional corner localized states on a 4×4 square lattice array of 16 superconducting qubits. The initial ground state of the system at half-filling, as a product of four identical entangled 4-qubit states, is prepared using an adiabatic scheme. During the pumping procedure, we adiabatically modulate the superlattice Bose-Hubbard Hamiltonian by precisely controlling both the hopping strengths and on-site potentials. At the half pumping period, the system evolves to a corner-localized state in a quadrupole configuration. The robustness of the second-order topological pump is also investigated by introducing different on-site disorder. Our Letter studies the topological properties of high-order topological phases from the dynamical transport picture using superconducting qubits, which would inspire further research on high-order topological phases.

Background: Castleman disease (CD) is an uncommon lymphoproliferative disorder with distinct pathological characteristics. Unicentric Castleman disease (UCD) presents as a single lymph node enlargement, often without significant symptoms. Complete surgical resection is the standard treatment for UCD. This study aimed to explore the clinicopathological features of UCD in a Taiwanese population., Methods: We retrospectively identified 12 patients with UCD who had undergone surgical treatment between January 1, 2006 and June 30, 2022 at the National Taiwan University Hospital. Clinical and radiological findings were retrieved from medical records. All available pathological slides were reviewed., Results: The patients' mean age was 38.1 years (range, 17 to 69); five (41.7%) were male, and seven (58.3%) were female. Nearly all cases of UCD were in the mediastinum, except for one case in the neck. Most patients were asymptomatic and without abnormal laboratory test results. Computed tomography revealed well-defined tumor borders, contrast enhancement, and occasional calcification. Ten patients underwent en bloc tumor resection, while the remaining two underwent partial resection. Among them, seven (58.3%) underwent video-assisted thoracoscopic surgery (VATS), and four (33.3%) underwent thoracotomy. The mean follow-up duration was 92 months. The patients who underwent total resection had no recurrence., Conclusion: Detailed clinicopathological information on UCD in the Taiwanese population is present in our article. Both complete and partial surgery are effective for treatment. VATS may be preferred over thoracotomy due to less operative time and bleeding., Competing Interests: Declaration of competing interest The authors have no conflicts of interest relevant to this article., (Copyright © 2024 Formosan Medical Association.

Introduction: Colorectal cancer leads to peritoneal metastasis in 8-15 % of cases and necessitates treatments, such as hyperthermic intraperitoneal chemotherapy (HIPEC). However, HIPEC may result in perioperative complications, some often overlooked, such as abdominal compartment syndrome., Case Presentation: A 52-year-old female with colorectal cancer and peritoneal metastasis underwent debulking surgery followed by HIPEC. During HIPEC, a sudden increase in airway pressure and severe hypotension were noted. Pneumothorax with abdominal compartment syndrome (ACS) was suspected and HIPEC was terminated. Despite intravenous fluids and vasopressors, she experienced circulatory and respiratory collapse. Laparotomy sutures were promptly removed, which effectively alleviated the intra-abdominal hypertension and immediately restored the vital signs. An inadequately repaired diaphragm defect was identified and repaired. A chest tube was inserted for pleural effusion., Discussion: ACS is characterized by an increase in abdominal cavity pressure above 20 mmHg, leading to end-organ damage. It can mimic physiological effects of HIPEC and result in adverse outcomes. Early detection of ACS is essential, especially when complicated by pneumothorax from diaphragmatic tumor dissection. The closed technique for HIPEC, while efficient, can increase the risk of ACS and requires careful management., Conclusions: This case underscores the complexity of HIPEC and the importance of promptly identifying and managing ACS during the procedure. Monitoring intra-abdominal pressure during HIPEC is essential. Thoroughly check for iatrogenic injuries, including the diaphragm, is crucial before starting before HIPEC., Competing Interests: Conflict of interest statement None declared., (Copyright © 2024.

Background: Oxaliplatin is commonly used to treat gastrointestinal malignancies. However, its applications are limited due to potential adverse drug reactions (ADRs), particularly severe anaphylactic shock. There is no method to predict or prevent ADRs caused by oxaliplatin. Therefore, we aimed to investigate the genetic HLA predisposition and immune mechanism of oxaliplatin-induced ADRs., Methods: A retrospective review was performed for 154 patients with ADRs induced by oxaliplatin during 2016-2021 recorded in our ADR notification system. HLA genotyping was conducted for 47 patients with oxaliplatin-induced ADRs, 1100 general population controls, and 34 oxaliplatin-tolerant controls in 2019-2023. The in vitro basophil activation test (BAT) was performed and oxaliplatin-specific IgE levels were determined., Results: The incidence of oxaliplatin-induced ADRs and anaphylactic shock in our cohort was 7.1% and 0.15%, respectively. Of the 154 patients, 67.5% suffered rash/eruption; 26.0% of the patients who could not undergo oxaliplatin rechallenge were considered to show oxaliplatin-induced immune-mediated hypersensitivity reactions (HRs). The genetic study found that the HLA-DRB∗12:01 allele was associated with oxaliplatin-induced HRs compared to the general population controls (sensitivity = 42.9%; odds ratio [OR] = 3.4; 95% CI = 1.4-8.2; P = 0.008) and tolerant controls (OR = 12; 95% CI = 2.3-63.7; P = 0.001). The in vitro BAT showed higher activation of CD63 + basophils in patients with oxaliplatin-induced HRs compared to the tolerant controls (P < 0.05). Only four patients (8.5%) with oxaliplatin-induced ADRs were positive for oxaliplatin-specific IgE., Conclusions: This study found that 26.0% of patients with oxaliplatin-induced ADRs could not undergo oxaliplatin rechallenge. HLA-DRB∗12:01 is regarded as a genetic marker for oxaliplatin-induced hypersensitivity., (Copyright © 2024 Japanese Society of Allergology. Published by Elsevier B.V. All rights reserved.)

To achieve a consensus on optimal blood pressure (BP) targets for older adults remains challenging, necessitating a trade-off between cardiovascular benefits and the risk of impaired organ perfusion. Evidence suggests that age and frailty have a minimal influence on the cardiovascular benefits of intensive BP control in community-dwelling elderly. Nonetheless, an increased incidence of acute kidney injury with intensive BP control has been observed in octogenarians. Therefore, it is recommended to maintain systolic BP below 130 mmHg for hypertensive patients aged 65-80 years. If well-tolerated, a systolic BP target below 120 mmHg can be recommended for patients with chronic kidney disease (CKD). However, no conclusive evidence supports a stringent BP target for patients aged 80 years and older. The selection of antihypertensive medications for elderly patients requires consideration of their cardiovascular condition and potential contraindications. Combination therapy may be necessary to achieve the desired BP target. Angiotensin-converting enzyme inhibitors or angiotensin receptor blockers are the primary choices for patients with CKD. Newer generation mineralocorticoid receptor antagonists may further reduce the risk of cardiovascular or renal events in this population. In conclusion, managing hypertension in elderly patients requires a personalized approach that balances cardiovascular benefits with potential risks, considering individual health profiles and tolerability., Competing Interests: Declaration of competing interest None, (Copyright © 2024 Formosan Medical Association.

Background: Left ventricular outflow tract obstruction (LVOTO) re-intervention is a significant cause of morbidity and mortality in patients with coarctation of the aorta (CoA) or interrupted aortic arch (IAA) after aortoplasty., Methods: This retrospective study analyzed data from neonates with IAA/CoA who underwent biventricular repair between 2012 and 2022. LVOTO events were defined by the detection of color Doppler flow acceleration ≥3.0 m/s at the valvular, subvalvular, or supravalvular regions via transthoracic echocardiography, and the necessity for surgical or catheter intervention to relieve the obstruction., Results: Among 121 neonates with CoA/IAA, 16 (13.7%) primary aortoplasty patients developed LVOTO. Additionally, one patient (25%) who underwent a staged Yasui operation developed LVOTO due to a narrowed ventricular septal defect-pulmonary atresia tunnel. During follow-up, 58% of patients with a bicuspid valve and 25% of patients with a subaortic ridge developed LVOTO. The combination of either a bicuspid valve, subaortic ridge, or an aortic valve annulus Z-score < -3.0 predicted a high re-intervention rate (7/8 [87.5%])., Conclusions: In patients with IAA/CoA, the presence of multiple risk factors, including a bicuspid valve, subaortic ridge, and an aortic valve annulus Z-score < -3.0, is associated with a significantly increased rate of re-intervention for LVOTO., Competing Interests: Declaration of competing interest none., (Copyright © 2024 Formosan Medical Association.

Background: The clinical utility of Bacteroides fragilis in treating autism spectrum disorder (ASD) remains unclear. Therefore, this randomized, double-blind, placebo-controlled study aimed to explore the therapeutic effects and safety of B. fragilis BF839 in the treatment of pediatric ASD., Methods: We examined 60 children aged 2-10 years diagnosed with ASD, and participants received either BF839 powder (10 g/bar with ≥10 6  CFU/bar of viable bacteria, two bars/day) or placebo for 16 weeks. The primary outcomes was Autism Behavior Checklist (ABC) score. The secondary outcomes were Childhood Autism Rating Scale (CARS), Social Responsiveness Scale (SRS), Normal Development of Social Skills from Infants to Junior High School Children (S-M), Gastrointestinal Symptom Rating Scale (GSRS) scores, and fecal microbiome composition. Assessments were performed on day 0 and at weeks 8 and 16., Results: Compared with the placebo group, the BF839 group showed significant improvement in the ABC body and object use scores at week 16, which was more pronounced in children with ASD aged <4 years. Among children with a baseline CARS score ≥30, the BF839 group showed significant improvements at week 16 in the ABC total score, ABC body and object use score, CARS score, and GSRS score compared to the placebo group. Only two patients (6.67%) in the BF839 group experienced mild diarrhea. Compared with baseline and placebo group levels, the BF839 group showed a significant post-intervention increase in abundance of bifidobacteria and change in the metabolic function of neuroactive compounds encoded by intestinal microorganisms., Conclusion: BF839 significantly and safely improved abnormal behavior and gastrointestinal symptoms in children with ASD., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Lin, Zeng, Lu, Li, Liu, Li, Chen and Deng.)

Objective: The purpose of this study was to report a case of herpes simplex virus-1 (HSV-1) keratitis misdiagnosed as fungal keratitis due to its clinical presentation being similar to that of fungal keratitis, ultimately diagnosed by NGS. Patients and Methods: A 59-year-old male presented with reduced vision in the right eye, combined with a history of trauma with vegetative matter. The corneal ulcer was accompanied with feathery infiltration, satellite lesion, and endothelial plaques. In vivo confocal microscopy (IVCM) showed hyper-reflective linear, thin, and branching interlocking structures. Fungal keratitis was diagnosed. Voriconazole 100 mg orally daily, topical tobramycin and 1% voriconazole were initiated empirically right away. The condition was aggravated and penetrating keratoplasty was performed. Anterior segment optical coherence tomography (AS-OCT) demonstrated the presence of plaques with a clear boundary between plaques and endothelium, resembling the AS-OCT images observed in cases of viral keratitis. Next-generation sequencing (NGS) further detected HSV-1 deoxyribonucleic acid, and no fungal component was found. Antifungal agents were discontinued and antiviral treatments were added. Results: We successfully treated a patient with HSV-1 keratitis who was misdiagnosed due to clinical features and IVCM findings similar to fungal keratitis. The patient's infection was controlled. At 2 years after surgery, the cornea recovered well. Conclusions: HSV-1 keratitis with atypical clinical presentation can be easily misdiagnosed. This case report emphasizes the importance of NGS in diagnosing the pathogens of keratitis.

This study aims to explore the associations and the underlying mechanism among dry eye disease (DED), air pollution, and meteorological conditions. DED is positively correlated with air pollutants (i.e., PM 2.5 , PM 10 , O 3 , NO 2 , CO, and SO 2 ) and meteorological conditions (i.e., high altitude and wind speed), while negatively associated with relative humidity. Both low and high air temperatures effect DED. Atmospheric pollutants affect DED mainly through necroptosis or autophagy, inflammatory responses, and oxidative stress. Meteorological factors affect DED not only by their own affects but also by dispersing the concentration of air pollutants, and then reducing the negative exposure. In summary, this review may expand the understanding of the effects of air pollution and meteorological factors on DED and emphasize the importance of air environmental protection., Competing Interests: The authors declare that they have no conflict of interests., (Thieme.

Background: Obesity may serve as a protective factor in blunt abdominal trauma (BAT) patients due to a "cushion effect". In this study, we aim to use computed tomography (CT) scans to measure abdominal adiposity and its correlation with injury severity in BAT patients., Methods: We conducted a retrospective analysis of male BAT patients who had undergone CT scans. Subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) were manually measured and height-normalized for analysis at lumbar levels L2 and L3. Statistical methods were used to compare differences in adiposity between patients with and without severe abdominal injuries. For controls, we also compared adipose tissue in patients with and without severe trauma to the chest, where less fat typically accumulates., Results: We included 361 male participants and conducted a comparative analysis of their demographic and injury characteristics. Patients without severe abdominal injuries had significantly higher SAT and VAT indices at both L2 and L3 (p < 0.05). However, these measures showed no significant differences between patients with and without severe chest trauma. Solid organ injuries, particularly liver injuries, were associated with decreased SAT and VAT., Conclusion: Increase abdominal adiposity was linked to lower abdominal injury severity and solid organ injuries, particularly liver injuries. In addition to conventional BMI for evaluating obesity, either subcutaneous or visceral adipose tissue over lumbar levels L2 and L3 can be used to assess the "cushion effect.", Competing Interests: Declaration of competing interest This study was approved by the Institutional Research Board of Our Institution (202100283B0) on 2022/05/03 for ethics approval and consent to participate.

A significant monkeypox (mpox) outbreak occurred in 2022, particularly involving sexual and gender minority (SGM) groups. Stigma and misperceptions have led to fear of being labeled a member of the SGM group when obtaining immunization for mpox. We hypothesized that the most recommended injection site, intradermal injection in the forearm, stresses stigmatization. We conducted an online survey in a medical center in Taiwan between May 2023 and June 2023 among adults who were going to receive the second preexposure vaccination. The questionnaire comprised questions about physical and psychological impacts of the first mpox vaccination and the preference for the second vaccination location and factors influencing the preference. A total of 2,827 individuals (98.4% male) completed the questionnaires. Intradermal injection in the forearm was related to greater physical and psychological impacts of local adverse events, especially discoloration. "Beauty," "scar," and "others' view" were the most significant factors influencing preference for vaccination regimens. Compared to intradermal injection in the forearm, subjects who cared about "others' views" were likely to prefer vaccination in the deltoid. The odds ratio for preferring intradermally injection in the deltoid over in the forearm was 1.88 (95% CI 1.38-2.56). The odds ratio for preferring subcutaneous injection in the deltoid over intradermally injection in the forearm was 1.69 (95% CI 1.23-2.32). The odds ratio for preferring intradermally injection in the deltoid regardless of the route over intradermally injection in the forearm was 2.11 (95% CI 1.53-2.92). This study demonstrated the adverse events of different mpox vaccination regimens and their association with stigma. Recognizing the factors affecting the preference for mpox vaccine regimens is crucial for easing the mental stress of vaccinee., (© 2024. The Author(s).)

The 2023 consensus from the Taiwanese Dermatological Association (TDA) and Taiwan Lung Cancer Society (TLCS) addresses the management of tyrosine kinase inhibitor (TKI)-induced skin toxicities in non-small cell lung cancer (NSCLC). Providing a comprehensive overview, the consensus reflects recent advances in understanding causes and developmental processes of TKI-related skin toxicities. Aimed at guiding clinicians in Taiwan, the consensus integrates new treatment perspectives while incorporating experiences from local dermatology experts. Recommendations underwent a voting process, achieving consensus when 75% or more of experts agreed, leading to their inclusion. Approved by over 90% of participants, the recommended treatment algorithms for major skin toxicities offer valuable insights for clinicians managing TKI-associated effects in NSCLC patients., Competing Interests: Declaration of competing interest The authors have declared that no conflict of interest exists., (Copyright © 2024 Formosan Medical Association.

The purpose of this study was to investigate whether and how albiflorin, a natural monoterpene glycoside, affects the release of glutamate, one of the most important neurotransmitters involved in neurotoxicity, from cerebrocortical nerve terminals (synaptosomes) in rats. The results showed that albiflorin reduced 4-aminopyridine (4-AP)-elicited glutamate release from synaptosomes, which was abrogated in the absence of extracellular Ca 2+ or in the presence of the vesicular glutamate transporter inhibitor or a P/Q-type Ca 2+ channel inhibitor, indicating a mechanism of action involving Ca 2+ -dependent depression of vesicular exocytotic glutamate release. Albiflorin failed to alter the increase in the fluorescence intensity of 3,3-diethylthiacarbocyanine iodide (DiSC 3 (5)), a membrane-potential-sensitive dye. In addition, the suppression of protein kinase A (PKA) abolished the effect of albiflorin on glutamate release. Albiflorin also reduced the phosphorylation of PKA and synaptosomal-associated protein of 25 kDa (SNAP-25) and synapsin I at PKA-specific residues, which correlated with decreased available synaptic vesicles. The results of transmission electron microscopy (TEM) also observed that albiflorin reduces the release competence of synaptic vesicles evoked by 4-AP in synaptosomes. In conclusion, by studying synaptosomally released glutamate, we suggested that albiflorin reduces vesicular exocytotic glutamate release by decreasing extracellular Ca 2+ entry via P/Q-type Ca 2+ channels and reducing PKA-mediated synapsin I and SNAP-25 phosphorylation.

Introduction: Generalized pustular psoriasis (GPP) is a rare and severe psoriasis subtype characterized by the rapid onset of coalescing sterile pustules over broad body areas and systemic inflammation. Data on its clinical course and outcomes in Taiwan are limited. We evaluated the clinical profile and outcomes of patients with GPP flares in Taiwan., Methods: This retrospective analysis included adult patients with moderate-to-severe GPP flares occurring in January 2008-December 2021. Data were extracted from medical charts and electronic health records in the Chang Gung Research Database. Statistical analyses were performed using SAS for Windows (version 9.4). Multivariate Poisson regression models were built to investigate different predictors of GPP flare rate., Results: Thirty-four patients with 81 moderate-to-severe GPP flares were identified. Of the 14 patients undergoing genetic analysis, 10 (71.4%) had an IL36RN mutation. Patients' mean age at the index GPP flare was 47.1 ± 16.5 years; 58.0% of the flares were severe, while 42.0% were moderate. Overall, 96.3% of GPP flares were treated with at least one systemic therapy, acitretin being the most prescribed (85.2%), followed by cyclosporine (45.7%) and methotrexate (18.5%). After treatment, the proportion of flares responding positively increased from 0% on day 2 to 6.2% by week 12. Patients were newly diagnosed with psoriasis (23.5%), hypertension (20.6%), diabetes mellitus (14.7%), psoriatic arthritis (2.9%), malignant tumor (8.8%), and depression/anxiety (2.9%) after enrollment. Complications occurring within 12 weeks of GPP flares included arthritis (25.9% of the flares), skin infection (8.6%), and other infections (2.5%). No fatalities were reported. In the multivariate model, former smokers, patients with hepatic disease, and patients with psoriatic arthritis had an increased GPP rate ratio (RR) of 13.33 (95% confidence interval, CI, 2.87-61.78), 14.08 (95% CI 3.04-65.29), and 34.84 (95% CI 4.77- 254.42), respectively. Contrarily, obese and rheumatoid arthritis patients had a lower GPP rate ratio of 0.21 (95% CI 0.08-0.54) and 0.07 (95% CI 0.006-0.78), respectively., Conclusions: Our findings highlight the complexity of GPP flare presentations and the need for individualized, patient-centered management approaches and continued research to improve affected individuals' care and outcomes., (© 2024.

(1) Background: Remimazolam is a newly developed sedative agent. The results of previous meta-analyses highlight the strengths of remimazolam for use during colonoscopy procedures. The primary aim of the present study was to investigate whether, in patients undergoing colonoscopy procedures (P), the use of remimazolam (I) compared with other sedative agents (C) could lead to a greater incidence of hypotension, bradycardia, and hypoxia (O). (2) Methods: In the following study, we conducted an extensive literature search using two electronic databases. We included all randomized control trials, which involved a comparison of the hemodynamic changes in remimazolam versus a placebo and other sedative agents during colonoscopy procedures. Data extraction, data synthesis, and the assessment of risk of bias were performed by the authors. (3) Results: A total of seven articles met our inclusion criteria. The combined analysis of the selected studies revealed no statistically significant difference in hypotension, bradycardia, or hypoxia incidence when comparing remimazolam and the control group. However, in comparison with the group administered propofol, the pooled data of the selected studies revealed statistically significant differences in the incidence of both hypotension and bradycardia but not hypoxia. (4) Conclusions: Our findings indicate that there is no significant difference in hypotension, bradycardia, and hypoxia incidence when comparing remimazolam and other agents. Nevertheless, when comparing the remimazolam and propofol groups, the results demonstrated statistically significant differences in the incidence of both hypotension and bradycardia but not hypoxia.

Background: The incidence of atrial fibrillation/atrial flutter (AF/AFL) in general population is lower in Asia compared to Western countries. It is unclear whether a similar trend exists among adults with congenital heart disease (ACHD). We determine the profile, risk factors, and impact of AF/AFL in an Asian ACHD cohort., Methods: We included all ACHD patients diagnosed in an Asia tertiary care center between 2007 and 2018, analyzing AF (sustained and paroxysmal AF) and AFL, collectively./Purpose., Results: The study encompassed 4391 patients (55.9% women), with 81% having simple, 16.3% moderate and 2.8% severe CHD. AF/AFL was observed in 6.7% of the patients, with 54.6% having paroxysmal AF, 27.3% sustained AF, and 18.1% AFL. Incidence of AF/AFL increased with age and was higher in patients with pulmonary hypertension (PH), severe CHD, and metabolic syndrome. We found a progressive trend in the onset age of arrhythmia: AFL at a younger age, followed by paroxysmal and sustained AF. Risk factors for AF/AFL included severe and moderate CHD, PH, previous interventions, and male sex (odds ratio 11.2 and 3.15, 2.03, 1.75, and 1.71, respectively). When stratifying by CHD severity, PH and male sex were significant risk factors in simple CHD, while only PH in severe CHD. Patients with AF/AFL had a significantly lower major adverse cardiovascular events-free survival rate., Conclusions: This large ACHD cohort from Asia exhibited a high incidence of AF/AFL, similar to Western reports. The risk of AF/AFL was primarily associated with hemodynamic factors such as PH and CHD severity., Competing Interests: Declaration of competing interest None, (Copyright © 2024 Formosan Medical Association.

Nest building is a vital behavior exhibited during breeding in birds, and is possibly induced by environmental and social cues. Although such behavioral plasticity has been hypothesized to be controlled by adult neuronal plasticity, empirical evidence, especially at the neurogenomic level, remains limited. Here, we aim to uncover the gene regulatory networks that govern avian nest construction and examine whether they are associated with circuit rewiring. We designed an experiment to dissect this complex behavior into components in response to pair bonding and nest material acquisition by manipulating the presence of mates and nest materials in 30 pairs of zebra finches. Whole-transcriptome analysis of 300 samples from five brain regions linked to avian nesting behaviors revealed nesting-associated gene expression enriched with neural rewiring functions, including neurogenesis and neuron projection. The enriched expression was observed in the motor/sensorimotor and social behavior networks of female finches, and in the dopaminergic reward system of males. Female birds exhibited predominant neurotranscriptomic changes to initiate the nesting stage, while males showed major changes after entering this stage, underscoring sex-specific roles in nesting behavior. Notably, major neurotranscriptomic changes occurred during pair bonding, with minor changes during nest material acquisition, emphasizing social interactions in nest construction. We also revealed gene expression associated with reproductive behaviors and tactile sensing for nesting behavior. This study presents novel neurogenomic evidence supporting the hypothesis of adult neural plasticity underlying avian nest-construction behavior. By uncovering the genetic toolkits involved, we offer novel insights into the evolution of animals' innate ability to construct nests., (© The Author(s) 2024.

Objectives: The evaluation of Fontan-associated liver disease is often challenging. Diffusion-weighted magnetic resonance imaging can detect hepatic fibrosis from capillary perfusion and diffusion abnormalities from extracellular matrix accumulation. This study investigated its role in the evaluation of liver disease in Fontan patients and explored possible diagnostic methods for early detection of advanced liver fibrosis., Methods: Stable adult Fontan patients who could safely be examined with magnetic resonance imaging were enrolled, and blood biomarkers, transient elastography were also examined., Results: Forty-six patients received diffusion-weighted imaging; and 58.7% were diagnosed with advanced liver fibrosis (severe liver fibrosis, 37.0%, and cirrhosis 21.7%). Two parameters of hepatic dysfunction, platelet counts (Spearman's ρ: -0.456, P = 0.001) and cholesterol levels (Spearman's ρ: -0.383, P = 0.009), decreased with increasing severity of fibrosis. Using transient elastography, a cut-off value of 14.2 kPa predicted the presence of advanced liver fibrosis, but with a low positive predictive value. When we included platelet count, cholesterol, post-Fontan years and transient elastography values as a composite, the capability of predicting advanced liver fibrosis was the most satisfactory (C statistic 0.817 ± 0.071, P < 0.001). A cut-off value of 5.0 revealed a sensitivity of 78% and a specificity of 82%., Conclusions: In Fontan patients, diffusion-weighted imaging was helpful in detecting liver fibrosis that was correlated with hepatic dysfunction. A simple score was proposed for long-term surveillance and early detection of advanced liver disease in adult Fontan patients. For adult Fontan patients with a calculated score > 5.0, we may consider timely diffusion-weight imaging and early management for liver complications., (© The Author(s) 2024.

Stainless steel grade 430 is a type of soft magnetic electromagnetic material with rapid magnetization and demagnetization properties. Considering the delay phenomenon during operation, this study selected 430 stainless steel as the material and explored various metallurgical methods such as magnetic annealing and the addition of Mo as well as increasing the Si content to investigate the microstructure, mechanical behavior, and magnetic properties of each material, aiming to improve the magnetic properties of 430 stainless steel. Experimental results showed that the four electromagnetic steel materials (430F, 430F-MA, 434, and KM31) had equiaxed grain matrix structures, and excellent tensile and elongation properties were observed for each specimen. Additionally, the magnetic properties of the 430F specimen were similar under the DC and AC-10 Hz conditions. According to the hysteresis curves under different AC frequencies (10, 100, 1000 Hz), both magnetic annealing and the addition of Mo could reduce the Bm, Br, and Hc values of the raw 430F material. Increasing the Si content resulted in a decrease in Hc values and an increase in Bm and Br values.

Sublobar resection has emerged as a standard treatment option for early-stage peripheral non-small cell lung cancer. Achieving an adequate resection margin is crucial to prevent local tumor recurrence. However, gross measurement of the resection margin may lack accuracy due to the elasticity of lung tissue and interobserver variability. Therefore, this study aimed to develop an objective measurement method, the CT-based 3D reconstruction algorithm, to quantify the resection margin following sublobar resection in lung cancer patients through pre- and post-operative CT image comparison. An automated subvascular matching technique was first developed to ensure accuracy and reproducibility in the matching process. Following the extraction of matched feature points, another key technique involves calculating the displacement field within the image. This is particularly important for mapping discontinuous deformation fields around the surgical resection area. A transformation based on thin-plate spline is used for medical image registration. Upon completing the final step of image registration, the distance at the resection margin was measured. After developing the CT-based 3D reconstruction algorithm, we included 12 cases for resection margin distance measurement, comprising 4 right middle lobectomies, 6 segmentectomies, and 2 wedge resections. The outcomes obtained with our method revealed that the target registration error for all cases was less than 2.5 mm. Our method demonstrated the feasibility of measuring the resection margin following sublobar resection in lung cancer patients through pre- and post-operative CT image comparison. Further validation with a multicenter, large cohort, and analysis of clinical outcome correlation is necessary in future studies.

The presence of feathers is a vital characteristic among birds, yet most modern birds had no feather on their feet. The discoveries of feathers on the hind limbs of basal birds and dinosaurs have sparked an interest in the evolutionary origin and genetic mechanism of feathered feet. However, the majority of studies investigating the genes associated with this trait focused on domestic populations. Understanding the genetic mechanism underpinned feathered-foot development in wild birds is still in its infancy. Here, we assembled a chromosome-level genome of the Asian house martin (Delichon dasypus) using the long-read High Fidelity sequencing approach to initiate the search for genes associated with its feathered feet. We employed the whole-genome alignment of D. dasypus with other swallow species to identify high-SNP regions and chromosomal inversions in the D. dasypus genome. After filtering out variations unrelated to D. dasypus evolution, we found six genes related to feather development near the high-SNP regions. We also detected three feather development genes in chromosomal inversions between the Asian house martin and the barn swallow genomes. We discussed their association with the wingless/integrated (WNT), bone morphogenetic protein, and fibroblast growth factor pathways and their potential roles in feathered-foot development. Future studies are encouraged to utilize the D. dasypus genome to explore the evolutionary process of the feathered-foot trait in avian species. This endeavor will shed light on the evolutionary path of feathers in birds., Competing Interests: Conflicts of interest The authors declare no conflict of interest., (© The Author(s) 2024.

The presence of spread through air spaces (STASs) in early-stage lung adenocarcinoma is a significant prognostic factor associated with disease recurrence and poor outcomes. Although current STAS detection methods rely on pathological examinations, the advent of artificial intelligence (AI) offers opportunities for automated histopathological image analysis. This study developed a deep learning (DL) model for STAS prediction and investigated the correlation between the prediction results and patient outcomes. To develop the DL-based STAS prediction model, 1053 digital pathology whole-slide images (WSIs) from the competition dataset were enrolled in the training set, and 227 WSIs from the National Taiwan University Hospital were enrolled for external validation. A YOLOv5-based framework comprising preprocessing, candidate detection, false-positive reduction, and patient-based prediction was proposed for STAS prediction. The model achieved an area under the curve (AUC) of 0.83 in predicting STAS presence, with 72% accuracy, 81% sensitivity, and 63% specificity. Additionally, the DL model demonstrated a prognostic value in disease-free survival compared to that of pathological evaluation. These findings suggest that DL-based STAS prediction could serve as an adjunctive screening tool and facilitate clinical decision-making in patients with early-stage lung adenocarcinoma.
