We developed a system to estimate the photovoltaic (PV) potential of urban buildings using a 3D city model at level of detail 2 (LOD2), considering an arrangement of solar panels. Although the PV potential estimation of buildings at the level of city districts prefers LOD2 data, many urban city districts with buildings capable of installing solar panels on façades do not have LOD2 data owing to the high production cost of LOD2 data. Therefore, we investigated the possibility of utilising LOD1 data instead of LOD2 data in the PV potential estimation of buildings at the level of city districts. We conducted an experiment in the investigation using 3D city model data from 24 city districts, which are most of the large cities with LOD2 data in Japan. The experiment results suggest that LOD1 would not be a substitute for LOD2 data in the PV potential estimation of building roofs. The cause of the inadaptability is that most roofs in LOD2 buildings have more small polygons than LOD1 building roofs. Roofs of a LOD2 building with many small polygons have fewer solar panels than roofs of a LOD1 building with a large polygon. On the contrary, the experiment results indicate that LOD1 may be a substitute directly for LOD2 in the PV potential estimation of building façades that are expected to be used as a mounting platform for solar panels in urban buildings from now on. The average of the relative differences in the calculated PV potential of building façades between using LOD1 data and using LOD2 data is approximately 10% in the experiment.

To date, the lead-free perovskite has shown remarkable progress in solar cell development owing to its outstanding properties. Here, we report on the structural, optical, and photovoltaic properties of methylammonium bismuth iodide ((CH3NH3)3Bi2I9, MBI) and cesium bismuth iodide (Cs3Bi2I9, CBI) hybrid perovskite solar cells (HPeSCs) fabricated using the hot immersion method (HIM) with changing the composition x, ((CH3NH3)1-xCsx)3Bi2I9; from x = 0 to x = 1.0. The compact MBI and CBI films were successfully fabricated on FTO glass substrates at x = 0 and x = 1, respectively. On the other hand, the CBI/MBI mixed structure with a rough surface was obtained in the range from x = 0.2 to x = 0.8. An incorporation of CBI in MBI showed improvement, especially in optical properties, indicating that the absorption region was extended toward a longer wavelength region with increasing x. Interestingly, the open-circuit voltage of the hybrid cell was higher than that of the MBI or CBI cell, whereas the short-circuit current was lower than that of the MBI or CBI cell. This work provides alternative ways to fabricate lead-free PeSCs using a simple and low-cost method in the future.

Based on the analysis of statistical and information sources, scientific publications, and the authors’ personal experience, the article analyzes the peculiarities of Japanese minimarkets that rank among amazing Japanese inventions, creations, and practices and have become an integral part of the Japanese way of life and a trademark of the country. In the academic literature, there have been no comprehensive works revealing this phenomenon so far, and their regional peculiarities, especially the geography of stores operated by different chains, are almost completely neglected. The purpose of this article is to highlight the key scientific discourse, to characterize the unique character and universality, which, in fact, constitutes the phenomenon of konbini, as well as to identify their regional features. The study clearly shows that these stores, which came to Japan from the United States in 1973, have been completely transformed and are constantly evolving, changing the store concept and presenting a globally unique phenomenon. It describes the characteristics of the leading chains of these stores in their endeavor to gain even greater popularity among consumers and the innovations that have emerged in recent years, including those caused by the Covid-19 pandemic. In revealing the phenomenon of konbini, the authors, on the one hand, note their transformation into an important element of social infrastructure, that meets the needs of modern society and is especially necessary in the context of rapidly progressing aging of the population, and, on the other hand, their certain negative impact, especially on the younger generation. The paper features an analysis of the regional characteristics of these stores and the copyrighted cartographic material illustrating them. It is revealed that, within prefectures, the location of konbini correlates with the number of inhabitants (the number of stores is proportional to the population of municipalities), and each of the 20 konbini chains operating in Japan is located in its own specific area. The authors conclude that konbini are in the interest of the development of the country’s regions as a whole, and their role in Japanese society cannot be overemphasized. The Japanese experience can be relevant to other countries, including Russian chain stores.

Potential contribution from gamma-ray sources to the Galactic diffuse gamma rays observed above 100 TeV (sub-PeV energy range) by the Tibet AS γ experiment is an important key to interpreting recent multimessenger observations. This paper reveals a surprising fact: none of the 23 Tibet AS γ diffuse gamma-ray events above 398 TeV within the Galactic latitudinal range of ∣ b ∣ < 10° come from the 43 sub-PeV gamma-ray sources reported in the 1LHAASO catalog, which proves that these sources are not the origins of the Tibet AS γ diffuse gamma-ray events. No positional overlap between the Tibet AS γ diffuse gamma-ray events and the sub-PeV LHAASO sources currently supports the diffusive nature of the Tibet AS γ diffuse gamma-ray events, although their potential origin in the gamma-ray sources yet unresolved in the sub-PeV energy range cannot be ruled out.

Introduction In the last decades, growing evidence suggests, that young adults and even adolescents consume more and more pornographic content, which might lead to behavioural addictions. Excessive pornography use was found to be associated with higher rates of sexual dysfunctions, such as genital dysfunction or disorders related to desire, arousal, orgasm and pain. The role of attachment style on sexual function has still rarely been investigated. Objectives To examine associations between sexual dysfunction, problematic pornography use and attachment styles in a Spanish-Hungarian sample. Methods A cross-sectional comparative study was carried out in 2023 which included a Hungarian (N=447; 63% female; age: 30,5±9,8) and a Spanish sample (N=201; 72% female; age: 40,7±14) from the general population. In the online survey, we used the Arizona Sexual Experiences Scale (ASEX) to measure sexual dysfunction, the Problematic Pornography Use Scale (PPCS) to assess pornographic content consumption within the theoretical framework of addiction and the Relationships Questionnaire to explore the attachment styles of the subjects. Results 13% of the Hungarian sample and 19% of the Spanish sample reported severe sexual dysfunction (ASEXTotal >19). The Hungarian sample reported more problems related to orgasm (climax and satisfaction). Overall, 7% of the Hungarian sample and 1% of the Spanish sample reported very severe problems (PPCSTotal >76) with pornography use. We found significant differences in every subscale and the Hungarian sample reportedly showed more difficulties in every aspect, especially in salience and mood change. Regarding attachment styles, the samples also showed significant differences (Hungarian: 31% secure, 26% anxious-ambivalent, 20% avoidant, 23% disorganized; Spanish: 53% secure, 11% anxious-ambivalent, 23% avoidant, 13% disorganized). In the combined sample, secure attachment style was associated with the least difficulties in sexual functioning, whereas subjects with anxious-ambivalent style reported more problems in sexual drive, arousal and erection. Disorganized attachment style was associated with the most severe dysfunction in orgasm (climax and satisfaction). The association between problematic pornography use and attachment styles was more consistent. Secure attachment style showed the least of problems, whereas subjects with anxious-ambivalent and disorganized attachment styles reported the most, especially in salience and mood change. Conclusions Our findings showed significant intercultural differences between the two samples and highlighted the potential role of attachment styles in sexual functioning and problematic pornography use. A more profound understanding of the relationship between attachment and sexual functioning could facilitate potential treatment of sexual dysfunctions by addressing attachment issues in psychotherapy.

Introduction Sexual dysfunctions are prevalent issues affecting individuals’ sexual well-being and relationships. These conditions encompass a range of difficulties in sexual functioning, from desire and arousal to orgasm and pain. Psychological factors, such as dysfunctional beliefs about sexuality, play a significant role in the development and perpetuation of sexual dysfunctions (Nobre, Pinto-Gouveia, 2006; Nobre, Pinto-Gouveia, 2008). Additionally, personality traits, particularly those associated with the Dark Triad (Machiavellianism, narcissism, and psychopathy), have been suggested as potential protective factors to sexual problems, probably in interaction with sexual assertiveness and a wider experience in sexual behavior (Pilch, Smolorz, 2019). Objectives This study investigates the interplay between sexual dysfunctions, sexual dysfunctional beliefs, and Dark Triad personality traits, and compares the differences and similarities in the two different cultural (Hungarian and Spanish) samples. Methods Both samples were collected online by sharing the questionnaires on various platforms. Apart from the demographic and sexuality related background questions (age, sex, gender, sexual orientation, sexual lifestyle, etc.) our set of questionnaires included the Arizona Sexual Experience Scale (ASEX), Sexual Dysfunctional Beliefs Questionnaire (SDBQ, Male and Female Version) and The Short Dark Triad Questionnaire (SD3). Results The Hungarian sample consists of 465 participants, the Spanish of 215. However, the processing of the data is still underway, our preliminary results show, that there is a connection between the number of dysfunctional beliefs and occurrence of sexual dysfunctions. Just like Dark Triad traits seem to have negative correlation with dysfunctions. Conclusions Our research gives an opportunity to a better understanding of the psychological background of sexual dysfunctions. By taking in consideration the relationship between dysfunctional beliefs and said disorders, professionals can optimize sexual education to aid the prevention of them. Nevertheless, our findings can help the practice of psychotherapy in finding more advanced treatments, thus improving individuals’ overall sexual, and general well-being.

Previously, we successfully introduced laeA gene into a fungal strain in order to significantly increase the production of a bioactive compound, allowing use to discover novel biological activity. To demonstrate the universal applicability of the laeA gene introduction strategy for taping the potential of fungal secondary metabolism, in this present study, we created a library of microorganisms which we had the laeA gene inserted, and from that library we aimed to isolate compounds which are produced at significantly greater quantities compared to the respective wild type strains. From this investigation, we were able to isolate sclerotinin A (1) from Pochonia sp. KTF-0504 strain. We revealed that 1 showed anti-malarial activity against Plasmodium falciparum parasite strains. On the other hands, 1 showed no anti-fungal activity against multidrug-sensitive budding yeast. Our study implies that the utilization of the laeA gene in fungi is a versatile method for the discovery of drug candidates., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Y.A., T.T., and K.I. are employees of Kikkoman Corporation.

Study Design: Multicenter, prospective registry study., Objective: To clarify minimal clinically important differences (MCIDs) for surgical interventions for spinal metastases, thereby enhancing patient care by integrating quality of life assessments with clinical outcomes., Background: Despite its proven usefulness in degenerative spinal diseases and deformities, the MCID remains unexplored regarding surgery for spinal metastases., Patients and Methods: This study included 171 (out of 413) patients from the multicenter "Prospective Registration Study on Surgery for Metastatic Spinal Tumors" by the Japan Association of Spine Surgeons. These were evaluated preoperatively and at 6 months postoperatively using the Face Scale, EuroQol-5 Dimensions-5 Levels (EQ-5D-5L), including the Visual Analog Scale, and performance status. The MCIDs were calculated using an anchor-based method, classifying participants into the improved, unchanged, and deteriorated groups based on the Face Scale scores. Focusing on the improved and unchanged groups, the change in the EQ-5D-5L values from before to after treatment was analyzed, and the cutoff value with the highest sensitivity and specificity was determined as the MCID through receiver operating characteristic curve analysis. The validity of the MCIDs was evaluated using a distribution-based calculation method for patient-reported outcomes., Results: The improved, unchanged, and deteriorated groups comprised 121, 28, and 22 participants, respectively. The anchor-based MCIDs for the EQ-5D-5L index, EQ-Visual Analog Scale, and domains of mobility, self-care, usual activities, pain/discomfort, and anxiety/depression were 0.21, 15.50, 1.50, 0.50, 0.50, 0.50, and 0.50, respectively; the corresponding distribution-based MCIDs were 0.17, 15,99, 0.77, 0.80, 0.78, 0.60, and 0.70, respectively., Conclusion: We identified MCIDs for surgical treatment of spinal metastases, providing benchmarks for future clinical research. By retrospectively examining whether the MCIDs are achieved, factors favoring their achievement and risks affecting them can be explored. This could aid in decisions on surgical candidacy and patient counseling., Level of Evidence: II., Competing Interests: The authors report no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

In vivo imaging of bacterial infection models enables noninvasive and temporal analysis of individuals, enhancing our understanding of infectious disease pathogenesis. Conventional in vivo imaging methods for bacterial infection models involve the insertion of the bacterial luciferase LuxCDABE into the bacterial genome, followed by imaging using an expensive ultrasensitive charge-coupled device (CCD) camera. However, issues such as limited light penetration into the body and lack of versatility have been encountered. We focused on near-infrared (NIR) light, which penetrates the body effectively, and attempted to establish an in vivo imaging method to evaluate the number of lung-colonizing bacteria during the course of bacterial pneumonia. This was achieved by employing a novel versatile system that combines plasmid-expressing firefly luciferase bacteria, NIR substrate, and an inexpensive, scientific complementary metal-oxide semiconductor (sCMOS) camera. The D-luciferin derivative "TokeOni," capable of emitting NIR bioluminescence, was utilized in a mouse lung infection model of Acinetobacter baumannii , an opportunistic pathogen that causes pneumonia and is a concern due to drug resistance. TokeOni exhibited the highest sensitivity in detecting bacteria colonizing the mouse lungs compared with other detection systems such as LuxCDABE, enabling the monitoring of changes in bacterial numbers over time and the assessment of antimicrobial agent efficacy. Additionally, it was effective in detecting A. baumannii clinical isolates and Klebsiella pneumoniae . The results of this study are expected to be used in the analysis of animal models of infectious diseases for assessing the efficacy of therapeutic agents and understanding disease pathogenesis., Importance: Conventional animal models of infectious diseases have traditionally relied upon average assessments involving numerous individuals, meaning they do not directly reflect changes in the pathology of an individual. Moreover, in recent years, ethical concerns have resulted in the demand to reduce the number of animals used in such models. Although in vivo imaging offers an effective approach for longitudinally evaluating the pathogenesis of infectious diseases in individual animals, a standardized method has not yet been established. To our knowledge, this study is the first to develop a highly versatile in vivo pulmonary bacterial quantification system utilizing near-infrared luminescence, plasmid-mediated expression of firefly luciferase in bacteria, and a scientific complementary metal-oxide semiconductor camera. Our research holds promise as a useful tool for assessing the efficacy of therapeutic drugs and pathogenesis of infectious diseases., Competing Interests: The authors declare no conflict of interest.

Study Design: Retrospective study., Objectives: To investigate the impact of diabetes mellitus on neurological recovery and determine the relationship between moderate-severe diabetes and neurological recovery in patients with cervical spinal cord injury (CSCI) without bone injury., Methods: A retrospective study was conducted on 389 consecutive patients aged ≥65 years with CSCI without bone injury across 33 medical institutes. The patients were divided into a nondiabetic group (n = 270) and a diabetic group (n = 119). Neurological outcomes were compared between the two groups through propensity score matching. The impact of moderate-severe diabetes (defined as hemoglobin A1c ≥ 7.0% or requiring insulin treatment) on neurological recovery was evaluated through multiple linear regression analysis., Results: Propensity score matching revealed no significant differences between the diabetic and nondiabetic groups in terms of American Spinal Injury Association (ASIA) impairment scale grade and mean total ASIA motor scores (AMS) at 6 months post-injury. Multiple linear regression analysis indicated that age on admission (B = -0.34; 95% confidence interval [CI], -0.59 to -0.08; P = 0.01), dementia (B = -16.50; 95% CI, -24.99 to -8.01; P < 0.01), and baseline total AMS (B = -0.62; 95% CI, -0.72 to -0.51; P < 0.01) were negative predictors of neurological recovery at 6 months post-injury. The presence of moderate-severe diabetes did not influence neurological recovery at 6 months post-injury., Conclusions: Diabetic patients with CSCI without bone injury achieved improvements in neurological function comparable to those of nondiabetic patients. Moderate-severe diabetes did not affect neurological recovery in patients with CSCI without bone injury., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background Context: Low back pain (LBP) frequently occurs in patients with lumbar disc herniation (LDH), however the extent to which discectomy ameliorates it and how preoperative LBP influences postoperative outcomes remains unclear., Purpose: To evaluate the improvement in LBP and its impact on postoperative patient-reported outcome measures (PROMs)., Study Design/setting: Multicenter retrospective observational study., Patient Sample: Patients undergoing discectomy for LDH at eight hospitals from April 2017 to March 2021., Outcome Measures: Data were collected on patients' backgrounds, operative factors, and PROMs, including the Numeric Rating Scale (NRS) for pain in the low back, buttock, or leg, EuroQol 5 Dimension (EQ-5D), Oswestry Disability Index (ODI) scores, and postoperative satisfaction., Methods: Patients were categorized into mild (NRS 0-3), moderate (NRS 4-7), or severe (NRS 8-10) LBP groups. Inverse probability weighting with propensity scores was used to adjust for demographic and clinical differences between groups. Chi-square tests and one-way analysis of variance were conducted to compare background data and clinical characteristics. Additionally, multivariate logistic regression was performed to identify risk factors for less than 50% improvement in LBP., Results: This study included 928 patients: 270 mild, 343 moderate, and 315 severe. After adjustment, preoperative NRS scores were significantly different across groups, with scores of 1.6 (SD 1.3), 5.6 (SD 1.0), and 8.8 (SD 0.9), respectively. Postoperative NRS scores also varied significantly, with worse outcomes observed in the severe group compared to the mild group, yet similar to the moderate group. A total of 46.8% of the mild group, 86.6% of the moderate group, and 72.9% of the severe group achieved a 50% decrease in NRS scores of LBP. Preoperative EQ-5D and ODI scores were significantly worse in the severe group compared to the mild or moderate groups, but postoperative scores were not significantly different between the severe and moderate groups. No significant differences in postoperative satisfaction were observed among the groups. Being female was a significant risk factor for less than 50% improvement in LBP (odds ratio = 1.56, p = 0.022)., Conclusions: Discectomy significantly improved LBP in patients with LDH, including those with moderate or severe LBP. Patients with severe LBP showed similar improvements in PROMs as those with moderate LBP. Female gender emerged as a significant risk factor for less than optimal improvement in LBP., Competing Interests: Declaration of competing interest During the preparation of this work, the authors used ChatGPT4 in order to assist with the English language editing.

Background: The effects of myocarditis after mRNA COVID-19 vaccination (mCV) on myocardial tissue, and the association between cardiomyocyte injury and clinical presentation, are not fully understood., Methods and Results: We retrospectively registered patients clinically diagnosed with myocarditis after the first or second mCV who underwent endomyocardial biopsy or autopsy from 42 participating centers in Japan. We investigated the histological features and their association with clinical presentation based on cardiomyocyte injury. Forty patients who underwent endomyocardial biopsy were included in the study. Of these, 19 (47.5%) showed mild lymphocytic infiltration and interstitial edema without cardiomyocyte injury. The remaining 21 (52.5%) patients showed cardiomyocyte injury accompanied by infiltrating inflammatory cells: 11 with lymphocytic infiltration, 7 with eosinophilic infiltration, and 3 with myocarditis with both lymphocyte and eosinophil infiltration. Compared with patients without cardiomyocyte injury, those with cardiomyocyte injury were clinically characterized by older age, a balanced sex distribution, less frequent chest pain, and a lower left ventricular ejection fraction. Fifteen of 21 (71.4%) patients with cardiomyocyte injury developed fulminant myocarditis, with 13 (86.7%) requiring mechanical circulatory support; in contrast, none of those without cardiomyocyte injury developed fulminant myocarditis (P<0.001)., Conclusions: Our histological examination of patients with myocarditis after mCV revealed varying degrees of cardiomyocyte injury, ranging from pronounced to absent, along with various types of myocarditis. Cardiomyocyte injury was strongly associated with the severity of myocarditis.

Allergen-specific antibodies (Abs), IgE, and IgG4 increase during the early phase of oral immunotherapy (OIT) of allergen food in patients; subsequently, IgE levels decrease and specific IgG4 levels increase after successful OIT treatment. The detailed profile of these Abs during OIT remains largely unclear. We developed a diagnostic tool to assess the OIT efficacy and extent of responsiveness based on a profiling method by identifying epitopes recognized by the Ab classes of IgE or IgG4. A peptide microarray followed by microplate analysis using synthetic peptides was used to identify 14 epitopes widely recognized by IgE and/or IgG4 in the serum samples of patients with OIT among the amino acid sequences of five major cow's milk allergens. The set of defined 14 epitopes clarified different epitope profiles of allergen-specific IgE and IgG4 in each patient's serum samples. Moreover, the total signal of Abs recognizing all 14 epitopes was equal to the sum of all individual epitope-specific Abs. It was further observed that the quantitative value of IgE concentrations of 14 epitopes-ALL correlated with the ImmunoCAP IgE value. These findings strongly imply that the quantity of IgE and IgG4 recognizing epitopes-ALL may easily be used to measure allergy severity. To investigate this potential, we developed an immunochromatographic method that can detect IgE and IgG4 levels in patient samples. This study clearly demonstrated the usefulness of the defined 14 epitopes and their mixture, "epitopes-ALL," and that the simple and reliable methods of immunochromatography and microplate analyses demonstrating the epitope profile of allergen-specific Abs are applicable for diagnostic use at multiple disease stages and the OIT-treatment course in patients with cow's milk allergy., 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.

Study Design: Prospective multicenter study., Objectives: Palliative surgery is crucial for maintaining the quality of life (QOL) in patients with spinal metastases. This study aimed to compare the short-term outcomes of QOL after palliative surgery between patients with metastatic spinal tumors at different segments., Methods: We prospectively compared the data of 203 patients with spinal metastases at 2-3 consecutive segments who were divided into the following three groups: cervical, patients with cervical spine lesions; thoracic, patients with upper-middle thoracic spine lesions; and TL/L/S, patients with lesions at the thoracolumbar junction and lumbar and sacral regions. Preoperative and postoperative EuroQol 5-dimension (EQ5D) 5-level were compared., Results: All groups exhibited improvement in the Frankel grade, performance status, pain, Barthel index, EQ5D health state utility value (HSUV), and EQ5D visual analog scale (VAS) postoperatively. Although preoperative EQ5D HSUVs did not significantly differ between the groups (cervical, 0.461 ± 0.291; thoracic, 0.321 ± 0.292; and TL/L/S, 0.376 ± 0.272), the thoracic group exhibited significantly lower postoperative EQ5D HSUVs than the other two groups (cervical, 0.653 ± 0.233; thoracic, 0.513 ± 0.252; and TL/L/S, 0.624 ± 0.232). However, postoperative EQ5D VAS was not significantly different between the groups (cervical, 63.4 ± 25.8; thoracic, 54.7 ± 24.5; and TL/L/S, 61.7 ± 21.9)., Conclusions: Palliative surgery for metastatic spinal tumors provided comparable QOL improvement, irrespective of the spinal segment involved. Patients with upper and middle thoracic spinal metastases had poorer QOL outcomes than those with metastases in other segments; however, sufficient QOL improvement was achieved., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background/aim: Nab-paclitaxel is used to treat patients with pancreatic cancer. However, it frequently induces peripheral neuropathy. Notably, pharmacokinetic factors may be associated with neuropathic symptoms as the onset depends on the cumulative dose. Therefore, we prospectively examined the association between the cumulative dose of nab-paclitaxel at the onset of peripheral neuropathy and polymorphisms of hepatic transporter genes., Patients and Methods: Patients with pancreatic cancer receiving nab-paclitaxel (125 mg/m 2 ) and gemcitabine (1,000 mg/m 2 ) were enrolled. Peripheral neuropathy was assessed using the Common Terminology Criteria for Adverse Events (CTCAE), Patient-Reported Outcomes CTCAE (PRO-CTCAE), and Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-Ntx), every 2-12 weeks, and every 4 weeks thereafter. solute carrier organic anion transporter family member 1B1 (SLCO1B1) 521T>C, 388A>G; SLCO1B3 rs11045585; ATP-binding cassette transporters, subfamily B, member 1 (ABCB1) 1236C>T, 2677G>T/A, 3435C>T; ABCC1 rs2644983; ABCC2 24C>T; and ABCG2 421C>A were analyzed by direct sequencing. Correlations between transporter genotypes and cumulative dose at symptom onset were assessed using Kaplan-Meier and log-rank tests., Results: In total, 25 patients were enrolled. The lowest median cumulative dose for nab-paclitaxel at peripheral neuropathy onset using PRO-CTCAE was 593 mg. By CTCAE it was 800 mg, and by FACT/GOG-Ntx it was 1,090 mg (p<0.0001). At symptom onset, patients with ABCC2 -24C/T genotype had received a significantly lower median cumulative dose by PRO-CTCAE (540 mg) than those with C/C (720 mg) (p=0.0188). However, the other polymorphisms studied were not associated with symptoms., Conclusion: Herein, we found for the first time that ABCC2 -24C/T genotype was significantly associated with the onset of nab-paclitaxel-induced peripheral neuropathy detected with PRO-CTCAE., (Copyright © 2024 International Institute of Anticancer Research (Dr. George J.

Cord blood transplantation (CBT) presents unique challenges related to inflammation during neutropenia, such as mucosal damage, infections, and the potential development of pre-engraftment syndrome or pre-engraftment immune reaction. These factors can contribute to significant inflammation and infection shortly after CBT. However, the effect of severe inflammation during neutropenia, specifically elevated C-reactive protein (CRP) level and body temperature, on post-transplant outcomes after CBT remains unclear. This retrospective study aimed to investigate the association between maximum CRP level, maximum body temperature during neutropenia, and post-transplantation outcomes in adult patients undergoing single-unit CBT. We retrospectively evaluated the impact of maximum CRP level and maximum body temperature during neutropenia on post-transplantation outcomes in adults who underwent single-unit unrelated CBT between 1998 and 2023 at our institution. A total of 336 adult patients were included in this study. The median maximum CRP level before neutrophil recovery was 7.75 mg/dL (interquartile range [IQR], 4.70 to 12.05 mg/dL) at a median of 14 d (IQR, 8 to 16 d). The median maximum body temperature before neutrophil recovery was 39.5°C (IQR, 39.0 to 40.0°C) at a median of 15 d (IQR, 12 to 17 d). In the multivariate analysis, a maximum CRP level≥20 mg/dL was significantly associated with lower neutrophil recovery (hazard ratio [HR], 0.37; 95% confidence interval [CI], 0.23 to 0.59; P < .001), lower platelet recovery (HR, 0.28; 95% CI, 0.16 to 0.48; P < .001), and a higher incidence of veno-occlusive disease/sinusoidal obstruction syndrome (HR, 16.42; 95% CI, 4.11 to 65.54; P < .001), which resulted in higher non-relapse mortality (NRM) (HR, 5.16; 95% CI, 2.62 to 10.15; P < .001) and worse overall survival (HR, 2.81; 95% CI, 1.66 to 4.78; P < .001). Similarly, a maximum body temperature≥40.5°C was significantly associated with lower neutrophil recovery (HR, 0.51; 95% CI, 0.33 to 0.79; P = .002), lower platelet recovery (HR, 0.55; 95% CI, 0.38 to 0.79; P = .001), higher incidence of grades III to IV acute GVHD (HR, 2.93; 95% CI, 1.24 to 6.88; P = .013), and extensive chronic GVHD (HR, 2.47; 95% CI, 1.22 to 4.97; P = .011), which resulted in higher NRM (HR, 3.43; 95% CI, 1.53 to 7.67; P = .002). Maximum CRP level and maximum body temperature during neutropenia were significantly associated with lower hematopoietic recovery and higher NRM following single-unit CBT in adults. Further studies are warranted to explore early intervention strategies aimed at preventing severe inflammation and improving post-transplant outcomes in single-unit CBT., (Copyright © 2024 The American Society for Transplantation and Cellular Therapy.

Mutations of KRAS, CDKN2A, TP53, and SMAD4 are the four major driver genes for pancreatic ductal adenocarcinoma (PDAC), of which mutations of KRAS and TP53 are the most frequently recognized. However, molecular-targeted therapies for mutations of KRAS and TP53 have not yet been developed. To identify novel molecular targets, we newly established organoids with the Kras mutation (Kras mu OR) and Trp53 loss of function using Cre transduction and CRISPR/Cas9 (Kras mu /p53 mu OR) from murine epithelia of the pancreatic duct in Kras LSL-G12D mice, and then analyzed the proteomic and metabolomic profiles in both organoids by mass spectrometry. Hyperfunction of the glycolysis pathway was recognized in Kras mu /p53 mu OR compared with Kras mu OR. Loss of function of triosephosphate isomerase (TPI1), which is involved in glycolysis, induced a reduction of cell proliferation in human PDAC cell lines with the TP53 mutation, but not in PDAC or in human fibroblasts without TP53 mutation. The TP53 mutation is clinically recognized in 70% of patients with PDAC. In the present study, protein expression of TPI1 and nuclear accumulation of p53 were recognized in the same patients with PDAC. TPI1 is a potential candidate therapeutic target for PDAC with the TP53 mutation., (© 2024 The Author(s).

Purpose: Semantic segmentation of tubular structures, such as blood vessels and cell membranes, is a very difficult task, and it tends to break many predicted regions in the middle. This problem is due to the fact that tubular ground truth is very thin, and the number of pixels is extremely unbalanced compared to the background., Methods: We present a novel training method using pseudo-labels generated by morphological transformation. Furthermore, we present an attention module using thickened pseudo-labels, called the expanded tube attention (ETA) module. By using the ETA module, the network learns thickened regions based on pseudo-labels at first and then gradually learns thinned original regions while transferring information in the thickened regions as an attention map., Results: Through experiments conducted on retina vessel image datasets using various evaluation measures, we confirmed that the proposed method using ETA modules improved the clDice metric accuracy in comparison with the conventional methods., Conclusions: We demonstrated that the proposed novel expanded tube attention module using thickened pseudo-labels can achieve easy-to-hard learning., (© 2023.

Brown adipose tissue (BAT) plays an important role in energy metabolism because it uses fatty acids for thermogenesis during cold exposure. Preclinical studies found that boysenberry anthocyanins (BoyACs) activate BAT. Therefore, the aim of this preliminary study was to evaluate how BoyAC intake affects BAT in humans. We performed an open-label single-arm nonrandomized study in healthy volunteers. Before and after 4 weeks of daily consumption of 100 ml boysenberry juice (BoyJ) containing 61 mg of BoyACs, participants were assessed at 24 °C and then after 1 h of mild cold exposure (18 °C). An infrared thermography camera was used to measure skin surface temperatures in the supraclavicular BAT region (Tscv) and the non-BAT region of the upper chest (Tch). Energy metabolism was measured by indirect calorimetry. For each endpoint, we calculated Δ as the difference between values before and after cold exposure and compared the values before and after BoyJ intake. 10 volunteers participated (age: 36.1 ± 4.1, body mass index (BMI): 20.9 ± 0.6). After BoyJ intake, ΔTscv-ch was significantly higher (p = 0.029), but Δ energy expenditure, Δ fat oxidation, and Δ carbohydrate oxidation were not significantly different. We found a significant positive correlation between BMI and Δfat oxidation with BoyJ intake. The results indicate that 4 weeks of BoyJ intake activates cold-induced thermogenesis in the scv-BAT but does not have a significant effect on energy metabolism. BoyJ intake may increase fat oxidation during cold exposure in individuals with higher BMI.Trial registry number: UMIN000043476, 05/03/2021., (© 2024. The Author(s).)

Background and Objectives: In geriatrics and dementia care, early diagnosis is crucial. We developed a dementia screening model using drawing features from clock drawing tests (CDT) and investigated the features contributing to the discrimination of dementia and its screening performance. Methods: This study included 129 older adults attending a dementia outpatient clinic. We obtained information on the diagnosis of dementia and CDT data from medical records and quantified 12 types of drawing features according to the Freedman scoring system. Based on the dementia diagnosis information, participants were assigned to two groups: 58 in the dementia diagnosis group and 71 in the non-diagnosis group. Using Boruta, an iterative feature selection algorithm, and a support vector machine, a machine learning method, we analyzed the drawing features contributing to dementia discrimination and evaluated discrimination performance. Results: Five types of drawing features were selected as contributors to discrimination, including "numbers in the correct position," "minute target number indicated," and "hand in correct proportion." These features exhibited a discriminating sensitivity of 0.74 ± 0.16 and specificity of 0.74 ± 0.18 for detecting dementia. Conclusion: This study demonstrated a method for identifying individuals likely to be diagnosed with dementia among patients attending a dementia outpatient clinic using drawing features. The knowledge of drawing features contributing to dementia differentiation may assist healthcare practitioners in clinical reasoning and provide novel insights for clinical practice. In the future, we plan to develop a primary screening for dementia based on machine learning using CDT.

Immunoglobulin A vasculitis (IgAV), previously known as Henoch-Schönlein purpura, is the most common form of systemic vasculitis in childhood. The primary organs involved are the skin, gastrointestinal (GI) tract, joints, and kidneys. The spectrum of GI involvement in IgAV ranges from being mild and self-limited to severe manifestations often requiring surgical intervention. Galactose-deficient IgA1 on the immunoglobulin hinge region and its immune complexes are thought to play a central pathogenetic role in IgAV, however, an association between such molecules and specific GI mucosal damage remains unclear. GI endoscopy (both upper and lower) shows a variety of mucosal findings, many of which are not specific for IgAV. In upper GI endoscopy, however, the mucosal features can be diagnostic when found localized in the more distal part of upper GI tract (second and/or third parts of the duodenum). Abdominal computed tomography and capsule endoscopy have demonstrated that the small intestine is most commonly involved in IgAV. The GI mucosal involvement when evaluated microscopically shows IgA deposition which is histologically diagnostic. Conversely, leukocytoclastic vasculitis is less useful. Since the 1960s, cases of duodenojejunitis, in which IgAV was suspected but evident purpura was not dermatologically present, have often been labeled as "idiopathic". In a pediatric case series, IgA enteropathy, without dermatological manifestations (i.e., purpura), was reported to have similar symptoms, as well as endoscopic characteristics and immunohistological findings as in IgAV. Subsequently, several case reports provide additional supportive evidence that IgA enteropathy must be a variant of IgAV. Thus, the immunologically driven auto-immune vasculitis results in the symptom complex dependent on the organ system involved, and the subsequent clinical features which are manifested. Present classification criteria are useful and universally available for diagnosing IgAV. However, based upon current knowledge including IgA enteropathy, minor modification of the IgAV criteria is proposed in the review., 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., (© 2024 Kato, Gold and Kato.)

Introduction: Behavioral Activation (BA) is a short-term cognitive behavioral therapy modality that stimulates activities that increase patients' reinforcement experiences. Recent research verified the effect of brief BA. However, despite the short intervention time per session, BA is difficult to implement during hospitalization due to its long implementation period., Objectives: To evaluate the clinical effectiveness of a brief BA program for people with depression in an inpatient setting., Methods: This study employed a single-group pre-post design. Fifteen patients who met the inclusion criteria participated in the trial after providing oral and written informed consent. In addition to their usual care, participants received four weekly sessions administered by a nurse. The primary outcome measures included the Beck Depression Inventory (BDI-II), which indicated patients' subjective depression severity. Clinical outcomes were measured at preintervention, immediate postintervention, and one-month postintervention., Results: Fourteen participants completed the BA program and were receptive to treatment. For the primary endpoint, BDI-II, there was an improvement in scores (25.60 to 22.73 to 22.06) between the baseline, postintervention, and 1-month postassessment, but not a significant change. For EQ VAS score, there was no significant change, but there was an improvement in EQ VAS score (51.53 to 52.20 to 55.13) between the baseline, postintervention, and 1-month postassessment. The mean total Global Assessment of Functioning score increased from 40.20 to 57.00 across the pre- and postassessment points ( p  < .0001)., Conclusion: The study comprised a brief BA intervention, with results suggesting that participants could complete the program without feeling burdened. Although there was no significant improvement in the general outcome, depression levels, and other outcomes improved. Thus, while there is a need to rethink BA intervention, this program may be a practical approach to improving depression and other outcomes., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Purpose: Cases of adenocarcinoma of the uterine cervix (AUC) have poorer prognoses than those of squamous cell carcinoma. Carbon-ion radiation therapy (CIRT) outcomes for AUC have been reported in retrospective or single-institutional prospective studies but not prospective multicenter studies. We present the results of CIRT for AUC in a prospective multicenter study using a nationwide hospital-based registry in Japan., Methods and Materials: Patients with locally advanced untreated AUC who received CIRT at 4 Japanese centers between June 2016 and April 2020 were included in this study. In the absence of organ dysfunction, up to 5 weekly 40 mg/m 2 cisplatin courses were administered. The primary endpoints were 2-year overall survival and local control rates. The secondary endpoints were 2-year disease-free survival rate and late adverse events (AEs)., Results: Forty-two patients were enrolled with a median age of 54 years (range, 34-76 years). Patients were diagnosed with stage IIB (n = 26), IIIB (n = 12), or IVA (n = 4) disease. The median follow-up period was 24 months. The 2-year overall survival, local control, and disease-free survival rates were 97.5% (95% CI, 92.7%-100.0%), 80.9% (95% CI, 66.9%-94.8%), and 64.3% (48.1%-80.4%), respectively. Two patients developed grade 3 rectum/sigmoid AE. One patient required urinary diversion surgery during a salvage operation for local tumor recurrence (grade 3 genitourinary AE). No other grade 3 or worse toxicities were reported., Conclusion: CIRT is an effective treatment for locally advanced AUC. Further research is required to validate the safety and efficacy of CIRT for AUC., (Copyright © 2024 The Author(s). Published by Elsevier Inc. All rights reserved.)

Terrestrial organisms have systems to escape from desiccation stresses. For example, tardigrades (also known as water bears) can survive severe dried and other extreme environments by anhydrobiosis. Although their extraordinary ability has enchanted people, little is known about the detailed molecular mechanisms of anhydrobiosis. Here, we focused on the tardigrade Ramazzottius varieornatus, one of the toughest animals on Earth. A transcriptome database of R. varieornatus shows that genes encoding a Ferritin-like protein are upregulated during desiccation or ultraviolet radiation. This protein shows sequence similarity to enigmatic proteins in desiccation-tolerant bacteria and plants, which are hypothesized to be desiccation-related. However, because these proteins lack detailed biological information, their functions are relatively unknown. We determined an atomic (1.05 Å) resolution crystal structure of a Ferritin-like protein from R. varieornatus. The structure revealed a dinuclear metal binding site, and we showed that this Ferritin-like protein has phosphatase activity toward several metabolite compounds including unusual nucleotide phosphates produced by oxidative or radiation damage. We also found that a homologous protein from a desiccation- and ultraviolet-tolerant bacterium Deinococcus radiodurans is a metabolite phosphatase. Our results indicate that through cleaning up damaged metabolites or regulation of metabolite levels, this phosphatase family can contribute to stress tolerances. This study provides a clue to one of the universal molecular bases of desiccation-stress tolerance., (© 2024 The Author(s).

The relationship between early childhood phthalate exposure and early adiposity rebound (EAR) is unclear. This study aimed to investigate the association between 1.5- and 3-year phthalate exposure and EAR and overweight/obesity in 7.5-year-old Japanese children. A total of 452 mother-child pairs were enrolled from the Aichi Regional Cohort of the Japan Environment and Children's Study. The children were followed up at birth and at 1.5, 2, 3, 4, 5, 6, and 7.5 years of age for physical examination. Human biomonitoring of 16 urinary metabolites of eight phthalates was performed at 1.5 and 3 years of age. Latent class mixed models, binary logistic regression, and quantile g-computation were performed to identify body mass index (BMI) trajectories and investigate the relationships of single or mixed phthalate exposure with EAR and overweight/obesity. A one-unit increase in log 10 -transformed 3-year-old Σdi(2-ethylhexyl) phthalate (ΣDEHP) exposure levels was significantly associated with 6-year-old BMI in girls. The 1.5-year mono-iso-butyl phthalate and 3-year Σdi-isodecyl phthalate exposure levels were significantly associated with the repeated measures of longitudinal BMIs in girls. Single phthalate exposure showed null associations with EAR or overweight/obesity in the 7.5-year-old children. Σdi-isononyl phthalate, ΣDEHP, and mono-n-butyl phthalate exhibited the highest proportion of partial positive weights of being in the EAR trajectory after confounder adjustment. Phthalate mixture exposure in 1.5- and 3-year-old children was not significantly associated with EAR. Early childhood phthalate exposure was not related to EAR or overweight/obesity in 7.5-year-old Japanese children. However, few phthalates were positively associated with longitudinal BMIs in girls., 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 Elsevier Inc.

Purpose: Mucinous neoplasms of the gastrointestinal tract are characterized by a propensity for metastasis to the peritoneum, resulting in peritoneal mucinous carcinomatosis (PMC). A subset of these tumors, most often originating in the appendix, harbor mutations in the GNAS oncogene. While the natural history of GNAS -mutant PMC varies, patient outcomes are generally poor, as is response to cytotoxic chemotherapy. The purpose of this study was to evaluate the clinical efficacy of single-agent palbociclib, a cyclin-dependent kinase (CDK)4/6 inhibitor, in patients with GNAS -mutant PMC., Patients and Methods: We enrolled 16 patients with PMC in a single-arm personalized cancer therapy trial. For all patients, tumor tissue and/or circulating tumor DNA genomic profiling using next-generation sequencing and, when possible, PD-L1 expression, tumor mutational burden, and microsatellite instability status was assessed. Twelve of 16 patients had previous disease progression on at least one previous line of chemotherapy. The primary tumor was appendix in 13 patients, unknown in two patients, and pancreas in one patient. Eleven cases were classified as low grade, and five as high grade., Results: In 13 of 16 patients, we observed a decrease in carcinoembryonic antigen (CEA), and in six patients, the CEA declined by >50%. As measured by clinical and modified peritoneal RECIST criteria, 50% of evaluable patients had stable disease after 12 months of palbociclib. At a median follow-up of 17.6 months, median survival has not been reached. Clinical response to CDK4/6 inhibition was mirrored in tumors with GNAS mutation and mucinous histology using an ex vivo preclinical platform., Conclusion: CDK4/6 inhibition with palbociclib had clinical activity in PMC characterized by mutations in GNAS that was superior to that previously reported with cytotoxic chemotherapy. CDK4/6 inhibition is a novel therapeutic strategy worthy of further evaluation in this subgroup of gastrointestinal neoplasms.

Background : Sarcopenia, the age-related loss of muscle mass, is a negative prognostic factor in gastrointestinal cancer. Sarcopenia combined with visceral obesity (sarcopenic obesity) is associated with poor outcomes. We explored the influence of obesity and other factors on the prognosis of patients with colorectal cancer diagnosed with sarcopenia. Methods : We enrolled 211 patients with colorectal cancer diagnosed with preoperative sarcopenic obesity who underwent radical resection at Osaka University Hospital between January 2009 and January 2012. Muscle mass was assessed using the psoas muscle mass index. Obesity was evaluated by measuring the visceral fat area in the umbilical region. Patients were categorized into two groups: sarcopenia with obesity (SO) and sarcopenia without obesity (non-SO). Overall survival, cancer-specific survival, and cancer-related relapse-free survival (CRRFS) were compared between the two groups. Patient characteristics, including age, sex, body mass index, serum albumin, C-reactive protein, tumor markers, prognostic nutritional index (PNI), modified Glasgow prognostic score (mGPS), and geriatric nutritional risk index (GNRI), were also analyzed. Results : CRRFS was significantly shorter in the SO group than in the non-SO group ( p = 0.028). PNI, mGPS, and GNRI were not identified as significant prognostic factors for CRRFS. Multivariate analysis highlighted sarcopenic obesity, elevated carcinoembryonic antigen levels, and unfavorable histological types as significant predictors of poor CRRFS outcomes. Conclusions : Sarcopenic obesity is an independent predictor of poor prognosis in patients with CRC. Thus, interventions aimed at increasing muscle mass and reducing visceral fat could potentially improve the prognosis of these patients.

The growing interest in high-efficiency solar energy technologies has driven research on multijunction solar cells to flourish over the last several years. This study sheds light on the optical, structural, and morphological aspects of the (CH 3 NH 3 ) 3 Bi 2 I 9 ((MA) 3 Bi 2 I 9 ) film by fabricating and analyzing it experimentally. This thorough investigation lays the groundwork for more research into the film's possible uses in solar cell technology. We performed simulations to enhance the efficiency of two-terminal (2T) perovskite/perovskite double junction and perovskite/perovskite/c-Si triple-junction solar cells (TJSC) by using the MA 3 Bi 2 I 9 material. The power conversion efficiency was greatly increased by using 2T triple-junction solar cells; the increase was around 116.59% from single junction (13.80-29.89%) and 31.91% from double junction (22.66-29.89%). As far as we know, this is the first investigation of the efficacy of MA 3 Bi 2 I 9 as a top layer in multijunction tandem configurations. This revolutionary approach allows both academics and industry experts to produce cost-effective and efficient tandem solar cells, thereby enhancing earth-based solar energy development.

In proliferating bacteria, growth rate is often assumed to be similar between daughter cells. However, most of our knowledge of cell growth derives from studies on symmetrically dividing bacteria. In many α-proteobacteria, asymmetric division is a normal part of the life cycle, with each division producing daughter cells with different sizes and fates. Here, we demonstrate that the functionally distinct swarmer and stalked daughter cells produced by the model α-proteobacterium Caulobacter crescentus can have different average growth rates under nutrient-replete conditions despite sharing an identical genome and environment. The discrepancy in growth rate is due to a growth slowdown associated with the cell cycle stage preceding DNA replication (the G1 phase), which initiates in the late predivisional mother cell before daughter cell separation. Both progenies experience a G1-associated growth slowdown, but the effect is more severe in swarmer cells because they have a longer G1 phase. Activity of SpoT, which produces the (p)ppGpp alarmone and extends the G1 phase, accentuates the cell cycle-dependent growth slowdown. Collectively, our data identify a coupling between cell growth, the G1 phase, and asymmetric division that C. crescentus may exploit for environmental adaptation through SpoT activity. This coupling differentially modulates the growth rate of functionally distinct daughter cells, thereby altering the relative abundance of ecologically important G1-specific traits within the population., Competing Interests: Competing interests statement:The authors declare no competing interest.

Immune checkpoint inhibitors have shaped the landscape of cancer treatment. However, many patients either do not respond or suffer from later progression. Numerous proteins can control immune system activity, including multiple tumor necrosis factor (TNF) superfamily (TNFSF) and TNF receptor superfamily (TNFRSF) members; these proteins play a complex role in regulating cell survival and death, cellular differentiation, and immune system activity. Notably, TNFSF/TNFRSF molecules may display either pro-tumoral or anti-tumoral activity, or even both, depending on tumor type. Therefore, TNF is a prototype of an enigmatic two-faced mediator in oncogenesis. To date, multiple anti-TNF agents have been approved and/or included in guidelines for treating autoimmune disorders and immune-related toxicities after immune checkpoint blockade for cancer. A confirmed role for the TNFSF/TNFRSF members in treating cancer has proven more elusive. In this review, we highlight the cancer-relevant TNFSF/TNFRSF family members, focusing on the death domain-containing and co-stimulation members and their signaling pathways, as well as their complicated role in the life and death of cancer cells., (© 2024.

Background: The utility of synthetic ECV, which does not require hematocrit values, has been reported; however, high-quality CT images are essential for accurate quantification. Second-generation Deep Learning Reconstruction (DLR) enables low-noise and high-resolution cardiac CT images. The aim of this study is to compare the differences among four reconstruction methods (hybrid iterative reconstruction (HIR), model-based iterative reconstruction (MBIR), DLR, and second-generation DLR) in the quantification of synthetic ECV., Methods: We retrospectively analyzed 80 patients who underwent cardiac CT scans, including late contrast-enhanced CT (derivation cohort: n = 40, age 71 ± 12 years, 24 males; validation cohort: n = 40, age 67 ± 11 years, 25 males). In the derivation cohort, a linear regression analysis was performed between the hematocrit values from blood tests and the CT values of the right atrial blood pool on non-contrast CT. In the validation cohort, synthetic hematocrit values were calculated using the linear regression equation and the right atrial CT values from non-contrast CT. The correlation and mean difference between synthetic ECV and laboratory ECV calculated from actual blood tests were assessed., Results: Synthetic ECV and laboratory ECV showed a high correlation across all four reconstruction methods (R ≥ 0.95, p < 0.001). The bias and limit of agreement (LOA) in the Bland-Altman plot were lowest with the second-generation DLR (hybrid IR: bias = -0.21, LOA: 3.16; MBIR: bias = -0.79, LOA: 2.81; DLR: bias = -1.87, LOA: 2.90; second-generation DLR: bias = -0.20, LOA: 2.35)., Conclusions: Synthetic ECV using second-generation DLR demonstrated the lowest bias and LOA compared to laboratory ECV among the four reconstruction methods, suggesting that second-generation DLR enables more accurate quantification.

Background: Standard care for unresectable locally advanced non-small-cell lung cancer (LA-NSCLC) involves chemoradiotherapy followed by durvalumab. The clinical significance of durvalumab after chemoradiotherapy in patients with LA-NSCLC having a performance status of 2 or aged ≥75 years, however, remains unclear. Therefore, we investigated the clinical benefit of durvalumab after daily carboplatin plus thoracic concurrent radiotherapy., Patients and Methods: In this prospective phase II study, daily low-dose carboplatin (30 mg/m 2 ) was administered before radiotherapy for the first 20 fractions and concurrent radiotherapy (60 Gy) followed by durvalumab. The primary endpoint was 12 months progression-free survival (PFS) rate from durvalumab initiation. The secondary endpoints included rate of therapeutic completion, PFS, overall survival, objective response rate, and safety., Results: Of 86 patients who underwent chemoradiotherapy with daily carboplatin from September 2019 to October 2021, 61 (70.9%) received durvalumab consolidation. The performance status was 0, 1, and 2 in 28 (45.9%), 26 (42.6%), and 7 (11.5%) patients, respectively. The rate of therapeutic completion for durvalumab was 26.2% (16/61). The PFS rate of 12 months after durvalumab initiation was 51.0%, indicating that the primary endpoint was achieved because the expected value of 35% calculated from previous studies was exceeded. The objective response rate after chemoradiotherapy and durvalumab was 47.0% and 57.4%, respectively. The median PFS and overall survival were 12.3 and 28.1 months, respectively. The most common adverse event in grades 3 or 4 was pneumonitis (8.2%). One patient died because of interstitial pneumonitis., Conclusions: Durvalumab consolidation after daily carboplatin with radiotherapy was effective and tolerable for LA-NSCLC vulnerable patients., (Copyright © 2024 The Author(s).

Background/aim: The aim of the study was to develop a novel predictive scoring system based on the dynamics of serum inflammatory indicators in immune checkpoint inhibitor (ICI) treatment on non-small-cell lung cancer (NSCLC) with bone metastases., Patients and Methods: Sixty patients with NSCLC and bone metastases treated with ICIs between January 2016 and March 2021 were included in the development cohort. Serum neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein (CRP) levels were assessed before (pre-value) and 6 weeks after (post-value) ICI treatment, and a novel predictive score was developed: pre-value ≥ post-value, 0 points; pre-value < post-value, 1 point; total score: 0-2 points. The associations of these dynamics and the score with clinical outcomes, including overall survival (OS), progression-free survival (PFS), response rate (RR) of bone metastases, and disease control rate (DCR), were evaluated. Furthermore, cross-validation was performed with 23 patients after April 2021 using the same inclusion criteria., Results: The patients with decreased serum inflammation levels had significantly better OS, PFS, and RR than those with increased levels. Applying the developed score to the development cohort, the patients with 0 points had significantly better OS, PFS, and RR than others. In multivariable analysis, the score independently predicted treatment response to ICI for bone metastasis and prognosis. Cross-validation showed that OS, PFS, and RR were significantly better in the patients in the 0-point group., Conclusion: The early NLR and CRP dynamics were associated with therapeutic responses to ICIs in NSCLC with bone metastases. Our novel scoring system based on these dynamics is simple and has a high predictive accuracy., (Copyright © 2024 International Institute of Anticancer Research (Dr. George J.

The roasting process of sesame oil is expected to alter its internal composition and stability under oxidation condition. Presumably, the effect of roasting may differ with oxidation conditions (i.e., thermal and photo-oxidation), but such studies have not been undertaken. To further evaluate this notion, several type of sesame oils (raw and refined as unroasted oil, and roasted oil) and rapeseed oils as comparison were subjected to thermal oxidation (120℃) and photo-oxidation (50,000 lx) for 5 and 10 hours. The result revealed that the roasting sesame oil exhibited good stability under thermal oxidation, possibly due to the change on antioxidant agents such as sesamol and Maillard products during the roasting process. In contrast, the refined sesame oil (unroasted) demonstrated high stability under photo-oxidation, indicating that the refining process has a more significant impact on the oxidative stability in sesame oil compared to the alterations in its components caused by the roasting process. Taken together, this study is the first to show that the roasting and refining processes of sesame oil alter its internal composition and show different variations in sesame oils' oxidative stability under thermal and photo-oxidation, which holds significance considering its global consumption.

Myxoid pleomorphic liposarcoma (MPLS) is an extremely rare tumor listed in the fifth edition of the WHO classification (2020). Histologically, it mainly comprises a mixture of myxoid and pleomorphic liposarcoma-like components. Genetically, it lacks FUS/EWSR1::DDIT3 fusion and MDM2 amplification. Herein, we describe an example of MPLS with rhabdoid cells in a 10-year-old girl who presented with a growing mass in the right inguinal region. The specimen from the wide excision measured 68 mm × 55 mm × 43 mm, and a circumscribed and lobulated mass was observed in the subcutaneous tissue. Histologically, oval-to-short, spindle-shaped, proliferating tumor cells with moderate nuclear atypia and mesh-like capillaries against a myxoid background were noted. Adipocytes were observed focally, while rhabdoid cells were observed multifocally. Immunohistochemically, the tumor showed inconsistent reactivity for desmin but was negative for MYOD1, myogenin, MDM2, and CDK4. Fluorescence in situ hybridization revealed no DDIT3 rearrangement. Despite adjuvant chemotherapy, the tumor metastasized to the thoracic cavity 24 months after excision. The metastatic lesions contained abundant lipoblasts rather than rhabdoid cells, and we concluded this tumor was a MPLS. The presence of rhabdoid cells could be a diagnostic pitfall, and recognizing such a variation in histology would help improve diagnostic accuracy., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

The aim of this study was to investigate whether super-resolution deep learning reconstruction (SR-DLR) is superior to conventional deep learning reconstruction (DLR) with respect to interobserver agreement in the evaluation of neuroforaminal stenosis using 1.5T cervical spine MRI. This retrospective study included 39 patients who underwent 1.5T cervical spine MRI. T2-weighted sagittal images were reconstructed with SR-DLR and DLR. Three blinded radiologists independently evaluated the images in terms of the degree of neuroforaminal stenosis, depictions of the vertebrae, spinal cord and neural foramina, sharpness, noise, artefacts and diagnostic acceptability. In quantitative image analyses, a fourth radiologist evaluated the signal-to-noise ratio (SNR) by placing a circular or ovoid region of interest on the spinal cord, and the edge slope based on a linear region of interest placed across the surface of the spinal cord. Interobserver agreement in the evaluations of neuroforaminal stenosis using SR-DLR and DLR was 0.422-0.571 and 0.410-0.542, respectively. The kappa values between reader 1 vs. reader 2 and reader 2 vs. reader 3 significantly differed. Two of the three readers rated depictions of the spinal cord, sharpness, and diagnostic acceptability as significantly better with SR-DLR than with DLR. Both SNR and edge slope (/mm) were also significantly better with SR-DLR (12.9 and 6031, respectively) than with DLR (11.5 and 3741, respectively) (p < 0.001 for both). In conclusion, compared to DLR, SR-DLR improved interobserver agreement in the evaluations of neuroforaminal stenosis using 1.5T cervical spine MRI., (© 2024.

Background: Interleukin-17 (IL-17) is elevated in human inflammatory and autoimmune diseases. The polymorphism in the promoter region of the IL-17 A gene is associated with susceptibility to several inflammatory diseases, including acute graft-versus-host disease (GVHD) following allogeneic hematopoietic cell transplantation from adult donors. However, the impacts of IL-17 A polymorphism on cord blood transplantation (CBT) outcomes remain unclear., Objective: The objective of this study was to assess the impact of IL-17 A polymorphism rs2275913 on GVHD, survival, relapse, non-relapse mortality (NRM), and hematopoietic recovery after CBT., Study Design: We conducted a retrospective analysis of data from adult patients who underwent single-unit CBT at our institution from January 2005 to March 2023 for whose recipient or donor DNA samples were available. IL-17 A genotyping was performed using real-time polymerase chain reaction with the TaqMan® SNP genotyping assay for rs2275913., Results: A total of 158 recipients and 136 donors were evaluated in this study. Multivariate analysis showed that rs2275913 GA or AA recipients were associated with increased risk of grades II to IV acute GVHD compared to GG recipients (hazard ratio [HR], 1.46; 95% confidence interval [CI], 1.00-2.13; P = 0.047). Serum IL-17 A levels at eight weeks were significantly higher in rs2275913 GA or AA recipients compared to GG. The rs2275913 polymorphism did not affect survival, relapse, NRM, or hematopoietic recovery after single-unit CBT., Conclusion: Our data showed recipient IL-17 A polymorphism rs2275913 was associated with the risk of grade II to IV acute GVHD in adults undergoing single-unit CBT. However, the rs2275913 polymorphism in recipients and donors did not affect survival or relapse. Thus, the polymorphism of IL-17 A rs2275913 in recipients might predict the risk of acute GVHD after single-unit CBT., Competing Interests: Declaration of competing interest The authors declare no competing financial interests., (Copyright © 2024 The Author(s).

Palpebral conjunctival hue alteration is used in non-invasive screening for anaemia, whereas it is a qualitative measure. This study constructed machine/deep learning models for predicting haemoglobin values using 150 palpebral conjunctival images taken by a smartphone. The median haemoglobin value was 13.1 g/dL, including 10 patients with <11 g/dL. A segmentation model using U-net was successfully constructed. The segmented images were subjected to non-convolutional neural network (CNN)-based and CNN-based regression models for predicting haemoglobin values. The correlation coefficients between the actual and predicted haemoglobin values were 0.38 and 0.44 in the non-CNN-based and CNN-based models, respectively. The sensitivity and specificity for anaemia detection were 13% and 98% for the non-CNN-based model and 20% and 99% for the CNN-based model. The performance of the CNN-based model did not improve with a mask layer guiding the model's attention towards the conjunctival regions, however, slightly improved with correction by the aspect ratio and exposure time of input images. The gradient-weighted class activation mapping heatmap indicated that the lower half area of the conjunctiva was crucial for haemoglobin value prediction. In conclusion, the CNN-based model had better results than the non-CNN-based model. The prediction accuracy would improve by using more input data with anaemia., (© 2024 The Author(s).

Hypomethylating agent treatment for myeloid leukemia associated with Down syndrome (ML-DS) has been scarcely reported. Herein, we collected information on azacitidine treatment for ML-DS in Japan. Forty-eight cycles of azacitidine treatment were performed for 12 patients, including 11 relapsed or refractory (R/R) patients. In 40 cycles, azacitidine was used as monotherapy. No azacitidine-related death was observed. One cycle concurrently administered with methotrexate-based intrathecal therapy was discontinued due to toxicities. Only 4 of the 19 cycles given in non-remission achieved complete or partial remission. In conclusion, although most toxicities were acceptable, azacitidine monotherapy might be insufficient for R/R ML-DS cases., (© 2024 Wiley Periodicals LLC.)
