Background: Tralokinumab, a monoclonal anti-IL-13 antibody, is approved for treating atopic dermatitis (AD). Real-world data on its effectiveness and safety are limited. Objective: To evaluate the real-world effectiveness and safety of tralokinumab and the transition of laboratory indexes during 24-week treatment for AD patients. Methods: At week 24, achievement rates of Eczema Area and Severity Index 75 (EASI 75), EASI 90, and investigator's global assessment 0 out of 1 in systemic therapy-naïve patients, 83.3%, 72.2%, and 44.4%, respectively, were higher than those in systemic therapy-experienced patients, 46.7%, 20.0%, and 6.7%, respectively. Serum levels of immunoglobulin E (IgE), thymus and activation-regulated chemokine (TARC), and lactate dehydrogenase (LDH) significantly decreased at week 24, whereas neutrophil-to-lymphocyte ratio (NLR) and systemic inflammation response index (SIRI) significantly decreased at week 12 from baseline. Twenty-nine patients (27.9%) experienced mild treatment-emergent adverse events. Results: At week 24, achievement rates of Eczema Area and Severity Index 75 (EASI 75), EASI 90, and investigator's global assessment 0 out of 1 in systemic therapy-naïve patients, 83.3%, 72.2%, and 44.4%, respectively, were higher than those in systemic therapy-experienced patients, 46.7%, 20.0%, and 6.7%, respectively. Serum levels of immunoglobulin E (IgE), thymus and activation-regulated chemokine (TARC), and lactate dehydrogenase (LDH) significantly decreased at week 24, whereas neutrophil-to-lymphocyte ratio (NLR) and systemic inflammation response index (SIRI) significantly decreased at week 12 from baseline. Twenty-nine patients (27.9%) experienced mild treatment-emergent adverse events. Conclusions: Tralokinumab treatment showed prosperous therapeutic effects and good tolerability in real-world practice for AD, with higher effectiveness in patients without prior systemic therapy compared with those with prior systemic therapy. Tralokinumab treatment significantly decreased clinical and laboratory indexes, EASI, Peak Pruritus-Numerical Rating Scale, IgE, TARC, LDH, NLR, and SIRI.

Background: Upadacitinib, a Janus kinase 1 inhibitor, is an effective medicine for moderate-to-severe atopic dermatitis (AD). Identifying long-term responders to upadacitinib is crucial for optimal treatment strategies in real-world clinical practice. To identify predictive factors for long-term high responders to upadacitinib 15 mg or 30 mg, defined as achievers of investigator's global assessment (IGA) 0/1 with ≥2-point improvement from baseline IGA at week 48. Methods: A retrospective study was conducted from August 2021 to September 2023 on 63 AD patients treated with upadacitinib 15 mg and 31 patients with 30 mg. Patients of each group were categorized into long-term high responders (achievers of IGA 0/1 at week 48) and low responders (non-achievers). We compared baseline values of clinical indexes and laboratory parameters between long-term responders and nonresponders. Results: In 15 mg group, long-term high responders showed lower rate of bronchial asthma (BA), lower values of baseline eczema area and severity index (EASI) of head and neck, IgE, and systemic inflammatory response index (SIRI) compared with low responders. In 30 mg group, long-term high responders showed lower baseline levels of IgE compared with low responders. Conclusion: Patients with lower baseline EASI of head and neck, IgE, or SIRI or without BA and those with lower baseline IgE may have a higher potential to become long-term high responders to upadacitinib 15 mg and 30 mg treatment, respectively.

Psoriasis is a complex, chronic inflammatory skin disease that significantly impacts patients' quality of life (QOL), especially in cases of genital, nail, and scalp psoriasis. Bimekizumab is an inhibitor of interleukin (IL)-17A and IL-17F and used for the treatment of psoriasis. The aim of this retrospective study was to evaluate the effectiveness of bimekizumab through in treating genital, nail, and scalp lesions with psoriasis over 24 weeks. The study was conducted from May 2022 and February 2024 on 52 psoriasis patients treated with bimekizumab. The therapeutic effects of bimekizumab were evaluated by the achievement of Physician's Global Assessment (PGA) rates of 0/1 on the genitals (genital-PGA), fingernails (PGA-F), scalp-specific PGA (ss-PGA), static PGA (sPGA), and the Dermatology Life Quality Index (DLQI) at weeks 4, 16, and 24. Bimekizumab treatment significantly improved genital, nail, and scalp lesions with psoriasis. At week 24, the achievement rate of genital-PGA 0/1, PGA-F 0/1, ss-PGA 0/1 was 96.2%, 66.7%, or 93.9%, and that of sPGA 0/1 or DLQI 0/1 was 93.9% or 83.3%, respectively. Bimekizumab was effective for genital, nail, and scalp lesions with psoriasis, difficult-to-treat lesions, and simultaneously improved QOL in a real-world clinical practice., (© 2024 Japanese Dermatological Association.)

Psoriasis is a chronic complicated inflammatory skin disease. Genital, nail, and scalp lesions with psoriasis are difficult-to-treat and significantly impair patients' quality of life (QOL). Deucravacitinib, a selective oral tyrosine kinase 2 (TYK2) inhibitor, may act as a novel therapeutic option that improves these challenging manifestations. A retrospective study was conducted from January 2023 and February 2024 on 70 psoriasis patients treated with deucrabacitinib 6 mg. We evaluated the achievement rates of genital physician's global assessment (genital-PGA) 0/1, PGA of fingernails (PGA-F) 0/1, scalp-specific PGA (ss-PGA) 0/1, whole-body static PGA (sPGA) 0/1, and dermatology life quality index (DLQI) 0/1 at weeks 4, 16, and 24. Deucravacitinib improved genital, nail, and scalp lesions as well as systemic eruption and QOL in patients with psoriasis. Deucravacitinib may act as a promising treatment option for these difficult-to-treat lesions with psoriasis., (© The Author(s) 2024.

The purpose of this study was to investigate factors that influence clinical outcomes after anterior cruciate ligament (ACL) reconstruction in patients aged ≥40 years. We studied 264 patients aged ≥40 and 154 patients aged ≤20 years who underwent ACL reconstruction at several surgical centers. A logistic regression analysis was conducted to identify factors that influenced the Knee Injury and Osteoarthritis Outcome Score (KOOS) at 1 year post-ACL reconstruction. In the older patient group, cartilage damage in the patellofemoral compartment at surgery was a significant risk factor for poor postoperative KOOS subscores (pain, activities of daily living [ADL], sports, and quality of life [QOL]). Articular cartilage damage in the lateral compartment also significantly influenced one of the postoperative KOOS subscores (symptoms). In the younger patient group, articular cartilage damage in any compartments did not influence the postoperative KOOS subscores; only two preoperative KOOS subscores (symptoms and QOL) significantly influenced their postoperative KOOS subscores. We concluded that the articular cartilage damage in the patellofemoral compartment at ACL reconstruction predicts poor KOOS subscores at the 1-year follow-up in patients aged ≥40 years.

Background: Previous clinical trials presented efficacy and safety of Janus kinase 1 inhibitor upadacitinib through 52 weeks for moderate-to-severe atopic dermatitis (AD)., Objectives: To assess the effectiveness and safety of upadacitinib through 48 weeks in real-world clinical practice for Japanese AD patients (aged ≥12 years)., Methods: This retrospective study included 287 patients with moderate-to severe AD treated with 15 mg ( n  = 216) or 30 mg ( n  = 71) of upadacitinib daily. Effectiveness was assessed using eczema area severity index (EASI) scores, atopic dermatitis control tool (ADCT), peak pruritus-numerical rating scale (PP-NRS), and investigator's global assessment (IGA). Safety was evaluated through the incidence of treatment-emergent adverse events., Results: From baseline, EASI, ADCT, PP-NRS, and IGA rapidly reduced at week 4, and the reduction was maintained until week 48 of treatment with upadacitinib at both doses. Achievement rates of EASI 75, EASI 90, and EASI 100 at week 48 were 63.5, 30.2, and 7.9 in 15 mg group, and 77.4, 54.8, and 3.2% in 30 mg group, respectively. Acne and herpes zoster were frequent, but no serious adverse events occurred., Conclusions: Upadacitinib was therapeutically effective and tolerable for moderate-to-severe AD through 48 weeks in real-world clinical practice.

Background: Janus kinase 1 inhibitor upadacitinib is therapeutically effective for atopic dermatitis (AD). However, predictive factors for high responders to upadacitinib have not been established in real-world clinical practice., Objectives: To identify predictive factors for responders to upadacitinib 15 mg or 30 mg, defined as achievers of investigator's global assessment (IGA) 0/1 with ≥ 2-point improvement from basal IGA., Methods: A retrospective study was conducted from August 2021 to July 2023 on 159 AD patients treated with upadacitinib 15 mg and 52 patients with 30 mg. Patients in each group were categorized into responders (achievers of IGA 0/1 at week 12) and non-responders (non-achievers). We compared baseline values of clinical and laboratory parameters between responders and non-responders. Logistic regression analysis was used to detect variables predicting responders. Receiver-operating characteristic curves were used for evaluating prediction capabilities of the variables., Results: In logistic regression analysis, responders to 15 mg upadacitinib were associated with lower total EASI and higher age whereas responders to 30 mg were associated with lower LDH and lower IgE., Conclusions: Lower total EASI and higher age may predict responders to upadacitinib 15 mg while lower IgE and lower LDH may predict responders to 30 mg.

Background: Deucravacitinib is a selective oral tyrosine kinase 2 (TYK2) inhibitor recently approved for psoriasis., Objectives: We aimed to evaluate the real-world effectiveness and safety of deucravacitinib for psoriasis., Methods: We analyzed 33 Japanese patients with psoriasis (23 with plaque psoriasis, eight with psoriatic arthritis, and two with erythrodermic psoriasis) from January 2023 to October 2023. All patients received deucravacitinib 6 mg daily until week 16., Results: At week 8, 12, or 16, the achievement rate of PASI 75 was 60.9%, 73.9%, or 78.3%, that of PASI 90 was 13.0%, 39.1%, or 52.2%, that of PASI 100 was 0%, 8.7%, or 13.0%, that of absolute PASI ≤2 was 34.8%, 65.2%, or 78.3%, respectively. The achievement rate of dermatology life quality index 0/1 at week 16 was 42.9%. Fourteen patients (42%) complained pruritus. Peak pruritus-numerical rating scale in patients with pruritus decreased by median [interquartile] 71.4 [50-80] % of baseline at week 2. Adverse events occurred in 18.2% of patients, which were mild and manageable., Conclusions: Deucravacitinib for patients with psoriasis was well-tolerated and gave favorable therapeutic effects in the real-world practice. Deucravacitinib treatment rapidly reduced pruritus.

Background: Though Janus kinase inhibitors such as upadacitinib rapidly relieve itch in atopic dermatitis (AD) patients, how early itch relief impacts later skin clearance is not examined., Objectives: This study aims to determine if early itch relief by upadacitinib could predict complete skin clearance in later phases., Methods: This retrospective study involved 105 patients with moderate-to-severe AD treated with upadacitinib 15 mg/day. Eczema area and severity index (EASI), atopic dermatitis control tool, and achievement rate of EASI 100 were evaluated at weeks 4, 12, and 24. The threshold of early peak pruritus-numerical rating scale (PP-NRS) predicting later skin clearance was assessed by area under the receiver-operating characteristic curve, and predictors for EASI 100 achievement were determined by logistic regression analysis., Results: The rate of achieving EASI 100 at week 24 was extremely higher in patients who achieved week 2 PP-NRS ≤ 1 (42.9%) than in non-achievers (1.4%). The logistic regression analysis showed that the achievement of week 2 PP-NRS ≤ 1 and low body mass index were associated with achievement of EASI 100 at weeks 12 and 24., Conclusions: The achievement of week 2 PP-NRS ≤ 1 may predict later skin clearance in upadacitinib treatment.

Here we present the Multisite Assembly of Gateway Induced Clones (MAGIC) system, which harnesses site-specific recombination-based cloning via Gateway technology for rapid, modular assembly of between 1 and 3 "Entry" vector components, all into a fourth, standard high copy "Destination" plasmid backbone. The MAGIC toolkit spans a range of in vitro and in vivo uses, from directing tunable gene expression, to driving simultaneous expression of microRNAs and fluorescent reporters, to enabling site-specific recombinase-dependent gene expression. All MAGIC system components are directly compatible with existing multisite gateway Tol2 systems currently used in zebrafish, as well as existing eukaryotic cell culture expression Destination plasmids, and available mammalian lentiviral and adenoviral Destination vectors, allowing rapid cross-species experimentation. Moreover, herein we describe novel vectors with flanking piggyBac transposon elements for stable genomic integration in vitro or in vivo when used with piggyBac transposase. Collectively, the MAGIC system facilitates transgenesis in cultured mammalian cells, electroporated mouse and chick embryos, as well as in injected zebrafish embryos, enabling the rapid generation of innovative DNA constructs for biological research due to a shared, common plasmid platform.

We analyzed the intraoperative kinematics of total knee arthroplasty (TKA) using a navigation system to investigate the influence of different inserts on kinematics. This was a retrospective observational study. The Vanguard individualized design (33 patients, 33 knees) XP and anterior-stabilized (AS) inserts were used in TKA for osteoarthritis. Kinematic data were intraoperatively recorded. The range of motion, tibiofemoral rotational angle, anteroposterior translation of the femur, and varus-valgus laxity were compared between the two inserts (XP vs. AS). There was no significant difference in the range of motion (extension: XP, 3.7° ± 3.3° vs. AS, 3.8° ± 3.3°, p  = 0.84; flexion: XP, 138.1° ± 10.2° vs. AS, 139.0° ± 13.3°, p  = 0.73). With the AS insert, the tibia was gradually internally rotated as the knee was flexed. At maximum extension, the internal rotation was smallest with AS (XP 6.5° ± 4.0° vs. AS 5.1° ± 3.4°, p  = 0.022), which was also associated with smaller anterior femoral translation (maximum extension: XP, 14.1 ± 4.8 mm vs. AS, 11.3 ± 4.7 mm, p  = 0.00036; 30°: XP, 23.7 ± 5.6 mm vs. AS, 20.7 ± 5.1 mm, p  = 0.000033; 45°: XP, 24.4 ± 4.9 mm vs. AS, 23.2 ± 4.5 mm, p  = 0.0038). The AS was associated with a lower varus-valgus laxity (30° XP 4.1° ± 3.4 vs. AS 3.3° ± 2.7°, p  = 0.036; 60°: XP, 3.2° ± 3.0° vs. AS, 2.4° ± 3.3°, p  = 0.0089). The AS insert facilitated sequential tibiofemoral rotation with varus-valgus stability in mid-flexion without restricting the range of motion., Competing Interests: None declared., (Thieme.

Bimekizumab, which suppresses both interleukin (IL)-17A and IL-17F, has recently been approved as a biologic for psoriasis. We aimed to evaluate the real-world effectiveness and safety of bimekizumab for psoriasis and to identify predictive factors for its treatment responsiveness. We analyzed 36 Japanese patients with psoriasis (19 with psoriasis vulgaris and 17 with psoriatic arthritis) from May 2022 to September 2023. All patients received bimekizumab (320 mg every 4 weeks) until week 16. Seventeen patients (43.2%) had experienced bio-switch. The median (interquartile range) baseline total psoriasis area and severity index (PASI) was 6 (3.2-20.0). Total PASI rapidly and significantly decreased at week 4 by a median 79.8% from baseline, and gradually decreased thereafter. The PASI on the trunk, and upper and lower limbs rapidly and significantly decreased at week 4 compared to baseline and plateaued thereafter. The neutrophil-to-lymphocyte ratio and neutrophil number significantly decreased at week 16 compared to baseline. At weeks 4, 8, 12, and 16, the achievement rate of absolute PASI ≤2 was 72.2%, 80.6%, 92.9%, and 96.4%, respectively; that of absolute PASI ≤1 was 41.7%, 61.3%, 85.7%, and 82.1%; that of PASI 75 was 55.5%, 52.9%, 69.7%, and 75.8%; that of PASI 90 was 36.1%, 50.0%, 57.6%, and 62.9%; and that of PASI 100 was 19.4%, 38.2%, 51.5%, or 57.6%, respectively. Linear multivariate regression analysis revealed that younger age was associated with a higher percentage reduction of total PASI at weeks 4 and 8. There were no serious or fatal adverse events during treatment. In conclusion, bimekizumab rapidly and remarkably reduced the total PASI together with high achievement rates of absolute PASI ≤1 and ≤2, and with favorable safety in real-world clinical practice. Younger age may be a predictive factor for a good treatment response to bimekizumab., (© 2024 The Authors.

Background: Atopic dermatitis (AD) is a chronic skin disease characterized by type 2-skewed immune responses, and significantly influenced by cytokines dependent on Janus kinases (JAKs). Upadacitinib, a JAK1 inhibitor, is effective for moderate-to-severe AD. This study aims to identify biomarkers that reflect long-term therapeutic effects of upadacitinib 15 mg or 30 mg., Methods: A retrospective study from August 2021 to July 2023 included 213 AD patients treated with upadacitinib 15 mg and 70 AD patients with 30 mg. We analyzed eczema area and severity index (EASI), peak pruritus-numerical rating scale (PP-NRS), serum immunoglobulin E (IgE), thymus and activation-regulated chemokine (TARC), lactate dehydrogenase (LDH), and total eosinophil count (TEC) at weeks 0, 4, 12, 24, 36, and 48 of treatment., Results: Both treatments with upadacitinib 15 mg and 30 mg significantly reduced EASI and PP-NRS scores over week 4 to 48 compared to baseline. Upadacitinib 15 mg or 30 mg treatment significantly decreased TEC compared to baseline through week 4 to 36 or week 4 to 48, respectively. The percent reduction of TEC correlated with those of EASI and PP-NRS through week 4 to 48 of treatment with upadacitinib 15 mg, or through week 12 to 48 with 30 mg, respectively. After adjusting for % reductions of other laboratory markers, the significance of correlations was preserved at weeks 36 and 48 of 15 mg treatment, while at weeks 4 and 36 of 30 mg treatment., Conclusion: The % reduction of TEC correlated with those of EASI and PP-NRS during upadacitinib treatment, indicating its potential as a biomarker reflecting treatment responses to upadacitinib in AD patients. However, the variability of significant correlation during treatment indicates that further inspection is needed for its usefulness in monitoring responses to upadacitinib treatment for AD., Competing Interests: HS received a lecture fee and research cost from AbbVie GK. TH and NK received lecture fees from AbbVie GK. The remaining 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 Hagino, Hamada, Yoshida, Fujimoto, Saeki and Kanda.)

Clinical trials and real-world studies have shown the effectiveness of upadacitinib for treating rash and pruritus in patients with atopic dermatitis (AD). This study aimed to determine whether the early reduction in rash or pruritus at week 12 of upadacitinib treatment could be maintained at later treatment stages. This retrospective study involved 227 and 73 patients with moderate-to-severe AD treated with 15 and 30 mg upadacitinib daily, respectively. The eczema area and severity index (EASI) scores, peak pruritus numerical rating scale (PP-NRS), and investigator's global assessment (IGA) were analyzed. At week 12, patients were divided into achievers and non-achievers of EASI 75, 90, 100, absolute EASI ≤ 2, IGA0/1, PP-NRS4, or absolute PP-NRS ≤ 1. Achievement rates for each endpoint were assessed at later time points (weeks 24, 36, and 48) in both groups. Week 12 achievers largely maintained their endpoint achievements until week 48, regardless of dosage (15 mg or 30 mg). Week 12 non-achievers saw an increasing achievement rate of EASI 75 until week 48. The initial reduction in rash and pruritus at week 12 persisted until week 48 with upadacitinib treatment, suggesting potential benefits for patients requiring prolonged treatment despite not achieving EASI 75 at week 12.

Background: Atopic dermatitis is characterized by persistent eczema and pruritus. Janus kinase inhibitors, including upadacitinib, are effective treatments for moderate-to-severe atopic dermatitis. If patients do not respond well to a certain dose of a Janus kinase inhibitor, increasing the dose may improve their treatment responsiveness., Objectives: We assessed the outcomes of a dose increase in upadacitinib from 15 mg to 30 mg for Japanese patients with moderate-to-severe atopic dermatitis., Methods: In 23 patients who showed insufficient responses to upadacitinib 15-mg treatment, the dose of upadacitinib was increased to 30 mg. We evaluated total Eczema Area and Severity Index (EASI), EASI on the head and neck, trunk, upper, or lower limbs, EASI of erythema, edema/papulation, excoriation, or lichenification, and Peak Pruritus Numerical-Rating Scale at baseline (onset of upadactinib 15 mg), week 0 (time of increase), and weeks 4 and 12 after the increase., Results: Total EASI, EASI on each anatomical site, EASI of each clinical sign, and Peak Pruritus Numerical-Rating Scale were markedly reduced at weeks 4 or 12 compared with week 0. After the dose increase, the achievement rates of EASI 75 and EASI 90 significantly improved; EASI 75 4.3%, 68.2%, and 66.7%; EASI 90 0%, 18.2%, and 38.1% at weeks 0, 4, and 12, respectively., Conclusions: These results suggest that upadacitinib 30 mg can ameliorate rash and pruritus insufficiently improved by upadacitinib 15 mg, and that the dose increase to 30 mg may be considered as a treatment option for patients with atopic dermatitis with a limited response to upadacitinib 15 mg., (© 2024.

Delayed coronary obstruction is a rare complication occurring after transcatheter aortic valve replacement (TAVR). Although TAVR has become popular, in some cases, the therapeutic strategy should be carefully selected depending on the patient's anatomical and/or functional restrictions. We report a rare case of delayed coronary obstruction in which coronary obstruction was caused by thick endothelialization of the nitinol frame of the prosthetic valve. A 79-year-old female who had undergone TAVR 4 months before presented with mild chest pain and was admitted to our institution. Computed tomography and coronary angiography revealed that the space from the sinus of Valsalva to the nitinol frame was narrow and separated from the inside of the nitinol frame because of critical endothelialization. Therefore, an emergency surgical aortic valve replacement was performed. The patient had an uneventful postoperative course and was discharged 20 days postoperatively without any complications., (© The Author(s) 2024.

Background: Atopic dermatitis (AD) is a chronic eczematous disease with severe pruritus. Janus kinase (JAK) inhibitors, upadacitinib, baricitinib, and abrocitinib, are systemic treatments for AD. The outcomes of switching from one JAK inhibitor to another have not been examined., Objectives: We assessed the outcomes of switching from baricitinib 4 mg to upadacitinib 30 mg in Japanese patients with moderate-to-severe AD., Methods: Twenty patients treated with baricitinib 4 mg, showing insufficient response or adverse events, were switched to treatment with upadacitinib 30 mg. We evaluated total eczema area and severity index (EASI), EASI at head and neck, trunk, upper, or lower limbs, EASI of erythema, edema/papulation, excoriation, or lichenification, and peak pruritus numerical-rating scale (PP-NRS) at baseline (start of baricitinib), weeks 0 (time of switching), and 4 and 12 after switching., Results: Total EASI, EASI at each anatomical site, EASI of each clinical sign, and PP-NRS were markedly reduced at weeks 4 or 12 compared to week 0. Achievement rates of more than 75% or 90% reduction of EASI from baseline significantly improved after switching., Conclusions: Switching from baricitinib 4 mg to upadacitinib 30 mg effectively improved rash and pruritus.

Background: Upadacitinib is an oral Janus kinase (JAK) 1 inhibitor approved in Japan for moderate-to-severe atopic dermatitis (AD), and it provides a high therapeutic efficacy., Objectives: We compared the therapeutic effects of upadacitinib on skin rashes of individual anatomical sites, head and neck, upper limbs, lower limbs, and trunk in patients with AD., Methods: From August 2021 to December 2022, 65 Japanese patients with moderate-to-severe AD (aged ≥ 12 years) were treated with oral once daily upadacitinib 15 mg plus twice daily topical corticosteroids of moderate-to-strongest classes., Results: The eczema area and severity indexes (EASIs) of individual sites decreased significantly at weeks 4, 12, and 24 compared to those at week 0 in parallel to total (whole body) EASI. The achievement rates of EASI 75 at week 24 and of EASI 90 at week 12 of lower limbs were significantly higher than those of trunk. The percent reductions of EASI of lower limbs at weeks 12 and 24 were significantly higher than those of head and neck and of trunk., Conclusions: Among the four anatomical sites, the treatment responsiveness to upadacitinib in lower limbs appeared the highest, while those in trunk and in head and neck appeared relatively lower.

To explore the incidence of abnormal vaginal cytology after total laparoscopic hysterectomy for the treatment of cervical intraepithelial neoplasia 3, we retrospectively analyzed the medical records of patients treated at NHO Shikoku Cancer Center (Japan) in 2014-2019. The cases of 99 patients who underwent a laparoscopic (n=36) or open (n=63) hysterectomy and postoperative follow-up were examined. Abnormal vaginal cytology was detected in 13.9% (5/36) of the laparoscopic-surgery (LS) group and 14.3% (9/63) of the open-surgery (OS) group. A vaginal biopsy was performed at the physicians' discretion; one LS patient and six OS patients were diagnosed with vaginal intraepithelial neoplasia. The cumulative incidence of abnormal vaginal cytology at 3 years post-hysterectomy was 21.4% (LS group) and 20.5% (OS group), a nonsignificant difference. A multivariate analysis showed that age > 50 years was the only independent risk factor for abnormal vaginal cytology among the covariates examined including age; body mass index; histories of vaginal delivery, abdominal surgery, and smoking; and surgical approach (hazard ratio 8.11; 95% confidence interval 1.73-37.98; p=0.01). These results suggest that the occurrence of abnormal vaginal cytology after a hysterectomy may not be influenced by the laparoscopic procedure but is associated with older age., Competing Interests: No potential conflict of interest relevant to this article was reported.

Atopic dermatitis (AD) is a chronic eczematous disease with various types of rash, erythema, edema/papulation, excoriation, or lichenification. Janus kinase 1 inhibitor upadacitinib is effective for moderate-to-severe AD. We aimed to investigate the therapeutic effects of upadacitinib on each rash type in AD patients in real-world clinical practice. Seventy-two Japanese patients with moderate-to-severe AD were treated with oral upadacitinib 15 mg/day plus topical corticosteroids. The Eczema Area and Severity Index (EASI) scores for erythema, edema/papulation, excoriation, or lichenification on the whole body or on head and neck, upper limbs, lower limbs, or trunk were assessed at weeks 0, 4, and 12 of treatment. The proportions of patients who achieved resolution or at least 75% reduction of EASI from baseline (EASI 75) for individual rash types were calculated at weeks 4 and 12 on the whole body or each anatomical site. The resolution rates for excoriation, erythema, edema/papulation, or lichenification on the whole body were 38.3%, 23.7%, 21.7%, and 8.3% at week 4 and 18.3%, 18.6%, 11.6%, and 13.3% at week 12, respectively. The EASI scores for all rash types significantly decreased at weeks 4 and 12 compared to week 0. The achievement rates of EASI 75 for excoriation, erythema, edema/papulation, or lichenification on the whole body were 67.2%, 66.7%, 49.2%, and 37.7% at week 4 and 57.3%, 65%, 41%, and 41% at week 12, respectively. The achievement rate of EASI 75 for erythema on head and neck at week 4 (45.3%) was lower than that on upper limbs (71%) and on lower limbs (70.8%), and that on head and neck at week 12 (42.2%) was lower than that on lower limbs (69.2%). These results indicate that upadacitinib is effective for all AD rash types, especially for excoriation and erythema, while head-and-neck erythema might be less responsive to upadacitinib., (© 2023 Japanese Dermatological Association.)

Upadacitinib, an oral Janus kinase 1 inhibitor approved for treating atopic dermatitis (AD), can cause adverse events such as herpes zoster (HZ) and acne. We aimed to identify background factors predicting the occurrence of HZ and acne during upadacitinib treatment in patients with AD. From August 2021 to December 2022, 112 Japanese patients with moderate-to-severe AD (aged ≥12 years) were treated with upadacitinib 15 mg/day (78 patients) or 30 mg/day (34 patients) plus topical corticosteroids or delgocitinib limited to head and neck for 3-9 months. AD patients with the occurrence of HZ during upadacitinib treatment had higher incidences for history of HZ and of bronchial asthma than those without in the upadacitinib 15 mg, 30 mg, and whole groups. AD patients with occurrence of HZ had higher pretreatment values of lactate dehydrogenase and eczema area and severity index on head and neck compared to those without in the upadacitinib 15 mg and whole groups. Logistic regression analysis revealed that history of HZ was associated with the occurrence of HZ in the upadacitinib 15 mg and whole groups. The proportion of underage patients (<18 years) was higher in patients with occurrence of acne compared to those without in the upadacitinib 30 mg group, but no significant differences were found in the other background factors between the two patient populations. History of HZ may predict the occurrence of HZ during upadacitinib treatment in patients with AD., (© 2023 Japanese Dermatological Association.)

Background: Breast cancer treatment sometimes causes a chronic swelling of the arm called breast cancer-related lymphedema (BCRL). Its progression is believed to be irreversible and is accompanied by tissue fibrosis and lipidosis, so preventing lymphedema from progressing by appropriate intervention at the site of fluid accumulation at an early stage is crucial. The tissue structure can be evaluated in real time by ultrasonography, and this study aims at assessing the ability of fractal analysis using virtual volume in detecting fluid accumulation within BCRL subcutaneous tissue via ultrasound imaging. Methods and Results: We worked with 21 women who developed BCRL (International Society of Lymphology stage II) after unilateral breast cancer treatment. Their subcutaneous tissues were scanned with an ultrasound system (Sonosite Edge II; Sonosite, Inc., FUJIFILM) using a 6- to 15-MHz linear transducer. Then, a 3-Tesla MR system was used to confirm fluid accumulation in the corresponding area of the ultrasound system. Significant differences in both H  + 2 and complexity were observed among the three groups (with hyperintense area, without hyperintense area, and unaffected side) ( p  < 0.05). Post hoc analysis (Mann-Whitney U test; Bonferroni correction p  < 0.0167) revealed a significant difference for "complexity." The evaluation of the distribution in Euclidean space showed that the variation of the distribution decreased in the order of unaffected, without hyperintense area, and with hyperintense area. Conclusion: The "complexity" of the fractal using virtual volume seems to be an effective indicator of the presence or absence of subcutaneous tissue fluid accumulation in BCRL.

The rapid naturalization of Bombus terrestris across the Nemuro Peninsula has led to a decline in two closely related native Japanese species, namely Bombus hypocrita sapporensis and Bombus cryptarum florilegus, both belonging to the common subgenus Bombus. Although it is widely believed that cross-mating of native and non-native species is influenced by the common male sex pheromone in this region, no study has been conducted to substantiate this claim. Thus, we investigated the cross-activities of male sex pheromones between native and non-native bumblebees, as well as the frequencies of cross-mating, using chemical and DNA assays. Our gas chromatography-electroantennographic detector analyses and behavioral tests revealed the presence of sex pheromonal cross-activities between B. terrestris and the two Japanese bumblebees species. Furthermore, DNA analyses revealed the occurrence of cross-mating between native and non-native species in the Nemuro Peninsula. Overall, these results indicate the immediate need for conservation measures to safeguard Japanese bumblebee populations in the Nemuro Peninsula., (© 2023. The Author(s).)

The authors evaluated the efficacy and safety of baricitinib, a Janus kinase 1/2 inhibitor, for atopic dermatitis (AD) in real-world practice. From August 2021 to September 2022, 36 patients aged ≥15 years with moderate to severe AD were treated with oral baricitinib 4 mg/day plus topical corticosteroids. Baricitinib improved clinical indexes; the percent reduction at weeks 4 and 12 was a median of 69.19% and 69.98% for the Eczema Area and Severity Index (EASI), 84.52% and 76.33% for the Atopic Dermatitis Control Tool, and 76.39% and 64.58% for Peak Pruritus Numerical Rating Score, respectively. The achievement rate of EASI 75 was 38.89% and 33.33% at weeks 4 and 12, respectively. The percent reduction of EASI in the head and neck, upper limbs, lower limbs, and trunk was 56.9%, 68.3%, 80.7%, and 62.5% at week 12, respectively, with a significant difference between the head and neck versus the lower limbs. Baricitinib decreased thymus and activation-regulated chemokine, lactate dehydrogenase, and total eosinophil count at week 4. Baseline EASI of the head and neck negatively correlated with percent reduction of EASI at week 4, while baseline EASI of the lower limbs positively correlated with percent reduction of EASI at week 12. Treatment-emergent adverse events included elevation of creatine phosphokinase (11.1%), herpes labialis (5.6%), furuncle (8.3%), and exacerbation of AD (1%), without serious treatment-emergent adverse events. In this real-world study, baricitinib was well tolerated for patients with AD and achieved therapeutic effects comparable to those in clinical trials. High baseline EASI of the lower limbs might predict good treatment response at week 12, while high baseline EASI of the head and neck might predict poor treatment response at week 4 in baricitinib treatment for AD., (© 2023 Japanese Dermatological Association.)

Background: Lymphedema often affects the trunk after breast cancer surgery. Measuring volume baseline can help detect lymphedema-related changes early, thereby allowing for early intervention efforts. However, there is no quantitative method for detecting truncal lymphedema. As a preliminary investigation into the development of a new method for measuring truncal lymphedema, this study aimed to investigate the reliability and define the minimal detectable change (MDC) in posterior truncal thickness using a three-dimensional (3D) scanning system. Methods and Results: This observational study included 21 women who had undergone a mastectomy for breast cancer. The 3D images of every subject's trunk were captured by a handheld 3D scanner at two time points. The acquired 3D images were used to calculate the differences in thickness between the affected and unaffected sides at eight points on the trunk. The reliability was determined by checking for agreement between the trials (intraclass correlation coefficient) and by investigating the presence of systematic bias between the measurement error and true value (Bland-Altman analysis). Then, the MDC was calculated. For 14 of the 21 participants, 3D images without missing data at both time points were obtained. Analysis indicated that there was no systematic bias regarding the mean value at the seven body points. Fair-to-excellent reliability was shown at the five points in the middle of the trunk (MDC: 4.14-9.79 mm). The other three points (at the top and bottom of the trunk) had limited reliability. Conclusions: The 3D scanning system effectively measured the differences in thickness between the affected and unaffected sides of participants' posterior trunks, with fair-to-excellent reliability in the middle of the trunk.

Objectives: This study aimed to clarify the effect of an intervention using a head-mounted display with a web camera set at a modified pitch angle on spatial awareness, sit-to-stand movement, and standing balance in patients with left and right hemisphere damage., Methods: The participants were 12 patients with right hemisphere damage and 12 patients with left hemisphere damage. The line bisection test, a sit-to-stand movement, and balance assessment were performed before and after the intervention. The intervention task involved pointing at targets 48 times in an upward bias condition., Results: Significant upward deviation on the line bisection test was noted in patients with right hemisphere damage. The load on the forefoot during the sit-to-stand movement was significantly increased. The range of anterior-posterior sway during forward movement in the balance assessment was reduced., Conclusions: An adaptation task performed in an upward bias condition may produce an immediate effect on upward localization, sit-to-stand movement, and balance performance in patients with right hemisphere stroke., Competing Interests: CONFLICTS OF INTEREST: The authors have no conflicts of interest to declare., (2023 The Japanese Association of Rehabilitation Medicine.)

Atopic dermatitis (AD) is a chronic inflammatory skin disease with severe itch. The eosinophil-to-lymphocyte ratio (ELR), neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR) are reported to reflect itch or the severity of AD. We examined if these parameters may act as indicators for therapeutic effects of the Janus kinase 1 inhibitor upadacitinib for patients with AD in real-world clinical practice. Between August 2021 and September 2023, 65 Japanese patients (aged ≥ 12 years) with moderate to severe AD were treated with 15 mg/day of oral upadacitinib, plus twice daily topical corticosteroids. Before treatment, the baseline ELR, NLR, MLR, and PLR levels positively correlated with the eczema area and severity index (EASI), while the baseline NLR and PLR levels positively correlated with the peak pruritus-numerical rating scale (PP-NRS). After upadacitinib treatment, ELR and NLR remarkably decreased at week 4 and the reduced levels were maintained until week 24, in parallel with EASI and PP-NRS, while MLR and PLR transiently reduced at week 4, but returned to baseline levels after week 12. The percent reduction of ELR significantly correlated with the percent reductions of EASI and PP-NRS at weeks 4, 12, and 24 of upadacitinib treatment. ELR may act as an indicator for the improvement of clinical signs and itch by upadacitinib treatment in AD.

Psoriasis is associated with cardiometabolic and cardiovascular diseases. Biologic therapy targeting tumor necrosis factor (TNF)-α, interleukin (IL)-23, and IL-17 may improve not only psoriasis but also cardiometabolic diseases. We retrospectively evaluated whether biologic therapy improved various indicators of cardiometabolic disease. Between January 2010 and September 2022, 165 patients with psoriasis were treated with biologics targeting TNF-α, IL-17, or IL-23. The patients' body mass index; serum levels of HbA1c, total cholesterol, high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol, triglyceride (TG), and uric acid (UA); and systolic and diastolic blood pressures were recorded at weeks 0, 12, and 52 of the treatment. Baseline psoriasis area and severity index (week 0) positively correlated with TG and UA levels but negatively correlated with HDL-C levels, which increased at week 12 of IFX treatment compared to those at week 0. UA levels decreased at week 12 after ADA treatment compared with week 0. HDL-C levels decreased 52 weeks after IXE treatment. In patients treated with TNF-α inhibitors, HDL-C levels increased at week 12, and UA levels decreased at week 52, compared to week 0. Thus, the results at two different time points (at weeks 12 and 52) were inconsistent. However, the results still indicated that TNF-α inhibitors may improve hyperuricemia and dyslipidemia.

Purpose: The objective of this study was to investigate factors that influence the prevalence of medial and lateral meniscal injuries at the time of anterior cruciate ligament (ACL) reconstruction in patients with ACL injuries., Methods: Patients with ACL injuries at 9 institutions were enrolled in this multicentre study. Age, sex, duration between injury and surgery, pivot shift test grade, anterior knee laxity determined using the Kneelax 3 arthrometer, and other variables were assessed by logistic regression analysis. Meniscal conditions were evaluated via arthroscopy., Results: In all, 830 patients were enrolled. The prevalence of medial and lateral meniscal tears was 32.0% (266 knees) and 26.5% (220 knees), respectively. Significant factors that influenced the prevalence of medial meniscal injuries were age [odds ratio (OR) 1.03; P = 0.000], side-to-side differences in instrumented anterior knee laxity before surgery (OR 1.12; P = 0.002), duration between injury and surgery (≥ 12 months) (OR 1.86; P = 0.023), and pivot shift test grade (OR 1.36; P = 0.014). Significant factors of lateral meniscal injury were side-to-side differences in anterior knee laxity before surgery (OR 1.12; P = 0.003) and the male sex (OR 1.50; P = 0.027)., Conclusion: Greater anterior knee laxity, age, a longer duration between injury and surgery, and a higher pivot shift test grade predicted medial meniscal injury. Greater anterior knee laxity and the male sex predicted lateral meniscal injury. In patients with ACL injuries, the importance of side-to-side differences in anterior knee laxity should be rediscovered from the viewpoint of meniscal conditions., Level of Evidence: Level III., (© 2021.

Background: Breast cancer-related lymphedema (BCRL) is a chronic swelling of the arm due to breast cancer treatment. Lymphedema is diagnosed and staged on the basis of limb circumference measurements and the patient's subjective symptoms, which have poor reproducibility and objectivity: these cannot detect any fluid accumulation in the tissue. Ultrasonography is a feasible noninvasive technique that can be used to evaluate tissue structure in real time. This study aimed to assess the ability of texture features for discriminating the presence of accumulated fluid within the subcutaneous tissue of BCRL using ultrasound (US) imaging. Methods and Results: This study included 20 women who were treated for unilateral breast cancer and who subsequently developed BCRL (International Society of Lymphology stage II). Subcutaneous tissue was scanned through an US system (Sonosite Edge II; Sonosite, Inc., FUJIFILM) using a 6- to 15-MHz linear transducer to assess the ability of texture features for discriminating the presence of accumulated fluid within the subcutaneous tissue of BCRL. Fluid accumulation was observed using a 3-Tesla MR system under double-echo steady-state conditions. There was a significant difference among the three groups (with hyperintense area, without hyperintense area, and unaffected side) in 11 of 14 textural features ( p  < 0.05). Post hoc analysis (Mann-Whitney U test; Bonferroni correction p  < 0.0167) revealed significant differences in seven textural features within the hyperintense area. Conclusions: This study revealed that seven texture features quantified by US imaging data can provide information regarding fluid accumulation in the subcutaneous tissue of lymphedema.

Background: Manual lymph drainage (MLD) is one of the common treatments for breast cancer-related lymphedema (BCRL). Although the primary goal of MLD is to drain the excessive fluid accumulated in the affected upper limb and trunk to an area of the body that drains usually, the use of MLD is decided based on swelling and subjective symptoms, without assessing whether there is fluid accumulated in the affected region. The purpose of this study was to examine truncal fluid distribution in a sample of BCRL patients and investigate any correlation between such fluid distribution and swelling or subjective symptoms. Methods and Results: An observational study was conducted with 13 women who had unilateral, upper extremity BCRL. Fluid distribution was evaluated by using two magnetic resonance imaging (MRI) sequences: half-Fourier acquisition single-shot turbo spin echo and three-dimensional double-echo steady-state. The presence of swelling was determined by lymphedema therapists, and subjective symptoms were measured by using a visual analog scale. On MRI, no participants had any free water signals in the trunk. However, seven had swelling and all 13 had some kind of subjective symptoms on the affected side of their trunk. Conclusions: These results suggest that swelling and subjective symptoms do not correlate with the presence of truncal fluid. For such cases, a different approach than MLD may be needed to address truncal swelling and related subjective symptoms. Checking for the presence of fluid in the truncal region may help MLD be used more appropriately.

The relationship of chronotype differences with dietary habits and health-related outcomes among elderly people is not fully understood, although sex and generation differences are observed in human chronotype. Accordingly, we analysed the association of chronotype (as assessed by the midpoint of sleep) with dietary intake and health-related quality of life (HRQoL) in elderly Japanese women. The subjects in this cross-sectional study were 1618 women aged 65 years and older who were grandmothers or acquaintances of dietetics students. The subjects were classified into quintiles with respect to the midpoint of sleep, from the earliest to the latest quintile. HRQoL was assessed by the Japanese version of the short-form 36-item health survey score. Mental health was assessed by the Center for Epidemiologic Studies Depression (CES-D) Scale. Dietary intake was assessed by a brief-type self-administered diet history questionnaire. A later midpoint of sleep was associated with a lower intake of vitamin D and a higher intake of bread and caffeinated drinks. No correlations were observed between chronotype and other nutrient and food intake. The subjects with a late midpoint of sleep (eveningness) showed poor general health perception (GH) and high CES-D scores. Other HRQoL scores did not differ among groups with different midpoints of sleep. In conclusion, chronotype as assessed by the midpoint of sleep is associated with poor GH and depressive tendencies in elderly Japanese women. Additionally, a few associations were found between dietary intake and chronotype in elderly Japanese women., (© The Author(s) 2021.)

Background: In 2014, the World Health Organization (WHO) released a classification system introducing neuroendocrine neoplasms (NENs) of the female reproductive tract, excluding the ovaries. This study aimed to evaluate whether retrospective adaption of the gastroenteropancreatic (GEP)-NEN classification is feasible for ovarian NENs (O-NENs) and correlates with prognosis., Methods: Sixty-eight patients diagnosed with carcinoid, small cell carcinoma (pulmonary type), paraganglioma, non-small/large cell neuroendocrine carcinoma (NEC), mixed NEC, or undifferentiated carcinomas at 20 institutions in Japan were included in this retrospective cross-sectional study. We identified O-NENs through central pathological review using a common slide set, followed by reclassification according to WHO 2010 guidelines for GEP-NENs. A proportional hazards model was used to assess the association of prognostic factors (age, stage, performance status, histology, and residual disease) with overall survival (OS) and progression-free survival (PFS)., Results: Of the 68 enrolled patients, 48 were eligible for analysis. All carcinoids (n = 32) were reclassified as NET G1/G2, whereas 14 of 16 carcinomas were reclassified as NEC/mixed adeno-NEC (MANEC) (Fisher's exact test; p < 0.01). The OS/PFS was 49.0/42.5 months and 6.5/3.9 months for NET G1/G2 and NEC/MANEC, respectively. Histology revealed that NEC/MANEC was associated with increased risk of death (HR = 48.0; 95% CI, 3.93-586; p < 0.01) and disease progression (HR = 51.6; 95% CI, 5.54-480; p < 0.01)., Conclusion: Retrospective adaption of GEP-NEN classification to O-NENs is feasible and correlates well with the prognosis of O-NENs. This classification could be introduced for ovarian tumors., (© 2020 S. Karger AG, Basel.)

Malignant pleural mesothelioma (MPM) is an asbestos-related aggressive malignant neoplasm. Due to the difficulty of achieving curative surgical resection in most patients with MPM, a combination chemotherapy of cisplatin and pemetrexed has been the only approved regimen proven to improve the prognosis of MPM. However, the median overall survival time is at most 12 mo even with this regimen. There has been therefore a pressing need to develop a novel chemotherapeutic strategy to bring about a better outcome for MPM. We found that expression of interleukin-1 receptor (IL-1R) was upregulated in MPM cells compared with normal mesothelial cells. We also investigated the biological significance of the interaction between pro-inflammatory cytokine IL-1β and the IL-1R in MPM cells. Stimulation by IL-1β promoted MPM cells to form spheroids along with upregulating a cancer stem cell marker CD26. We also identified tumor-associated macrophages (TAMs) as the major source of IL-1β in the MPM microenvironment. Both high mobility group box 1 derived from MPM cells and the asbestos-activated inflammasome in TAMs induced the production of IL-1β, which resulted in enhancement of the malignant potential of MPM. We further performed immunohistochemical analysis using clinical MPM samples obtained from patients who were treated with the combination of platinum plus pemetrexed, and found that the overexpression of IL-1R tended to correlate with poor overall survival. In conclusion, the interaction between MPM cells and TAMs through a IL-1β/IL-1R signal could be a promising candidate as the target for novel treatment of MPM (Hyogo College of Medicine clinical trial registration number: 2973)., (© 2020 The Authors.

A 69-year-old man developed sudden-onset chest and back pain and was brought to our hospital. Enhanced computed tomography (CT) revealed acute Stanford type B aortic dissection extending from the distal aortic arch to a 72 mm abdominal aortic aneurysm( AAA). The acute phase was managed by antihypertensive therapy, and the patient was followed up. Twenty days after the onset of aortic dissection, entry closure of aortic dissection by thoracic endovascular aortic repair and abdominal aorta replacement were performed simultaneously. Aorta remodeling was confirmed by postoperative CT, and the patient's postoperative course was uneventful. In the treatment of patients with acute aortic dissection and AAA, surgical intervention timing and strategy must be considered carefully.

Background: An extended-release, once-daily, oral formulation of tacrolimus is currently used after kidney transplantation as a substitute for the conventional twice-daily formulation. The purpose of this study was to provide a limited sampling strategy with minimum and optimum sampling points to predict the tacrolimus area under the concentration-time curve (AUC) after administration of once-daily tacrolimus in de novo adult kidney transplant patients., Methods: A total of 36 adult Japanese kidney transplant patients receiving once-daily tacrolimus were included: 31 were allocated to a study group to develop limited sampling strategy (LSS) model equations based on multiple stepwise linear regression analysis, and 5 were allocated to a validation group to estimate the precision of the LSS equations developed by the study group. Twelve-hour AUC (AUC0-12) was calculated by the trapezoidal rule, and the relationship between individual concentration points and AUC0-12 were determined by multiple linear regression analysis. The coefficient of determination (R2) was used to assess the goodness-of-fit of the regression models. Three error indices (mean error, mean absolute error, and root mean squared prediction error) were calculated to evaluate predictive bias, accuracy, and precision, respectively. Quality of the statistical models was compared with Akaike's information criterion (AIC)., Results: A four-point model using C0, C2, C4 and C6 gave the best fit to predict AUC0-12 (R2 = 0.978). In the three- and two-point models, the best fits were at time points C2, C4, and C6 (R2 = 0.973), and C2 and C6 (R2 = 0.962), respectively. All three models reliably estimated tacrolimus AUC0-12, consistent with evaluations by the three error indices and Akaike's information criterion. Practically, the two-point model with C2 and C6 was considered to be the best combination, providing a highly accurate prediction and the lowest blood sampling frequency., Conclusions: The two-point model with C2 and C6 may be valuable in reducing the burden on patients, as well as medical costs, for once-daily tacrolimus monitoring., Competing Interests: The authors have declared that no competing interests exist.

Small-cell lung cancer (SCLC) is characterized by one of neuroendocrine tumors, and is a clinically aggressive cancer due to its rapid growth, early dissemination, and rapid acquisition of multidrug resistance to chemotherapy. Moreover, the standard chemotherapeutic regimen in SCLC has not changed for three decades despite of the dramatic therapeutic improvement in non-SCLC. The development of a novel therapeutic strategy for SCLC has become a pressing issue. We found that expression of Eph receptor A2 (EphA2) is upregulated in three of 13 SCLC cell lines and five of 76 SCLC tumor samples. Genetic inhibition using siRNA of EphA2 significantly suppressed the cellular proliferation via induction of cell cycle arrest in SBC-5 cells. Furthermore, small molecule inhibitors of EphA2 (ALW-II-41-27 and dasatinib) also exclusively inhibited proliferation of EphA2-positive SCLC cells by the same mechanism. Collectively, EphA2 could be a promising candidate as a therapeutic target for SCLC., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Objective: We conducted a retrospective, multi-institutional, collaborative study to accumulate cases of neuroendocrine carcinoma of the endometrium, to clarify its clinicopathologic features, treatment, prognosis and prognostic factors to collate findings to establish future individualized treatment regimens. To our knowledge, this is the largest case study and the first study to statistically analyze the prognosis of this disease., Methods: At medical institutions participating in the Kansai Clinical Oncology Group/Intergroup, cases diagnosed at a central pathologic review as neuroendocrine carcinoma of the endometrium between 1995 and 2014 were enrolled. We retrospectively analyzed the clinicopathologic features, treatment, prognosis and prognostic factors of this disease., Results: A total of 65 cases were registered from 18 medical institutions in Japan. Of these, 42 (64.6%) cases were diagnosed as neuroendocrine carcinoma of the endometrium based on the central pathological review and thus included in the study. Advanced International Federation of Gynecology and Obstetrics stages (stage III and IV) and pure type small cell neuroendocrine carcinoma cases had a significantly worse prognosis. Upon multivariate analysis, only histologic subtypes and surgery were significant prognostic factors. Pure type cases had a significantly worse prognosis compared to mixed type cases and complete surgery cases had a significantly better prognosis compared to cases with no or incomplete surgery., Conclusion: Our findings suggest that complete surgery improves the prognosis of neuroendocrine carcinoma of the endometrium. Even among cases with advanced disease stages, if complete surgery is expected to be achieved, clinicians should consider curative surgery to improve the prognosis of neuroendocrine carcinoma of the endometrium., Competing Interests: No potential conflict of interest relevant to this article was reported., (Copyright © 2019.

Objective : To evaluate the relationship between systemic inflammatory biomarkers and efficacy of surgical treatment of primary varicose veins of the lower extremities. Methods : Total 12 patients who underwent endovenous laser ablation or stripping of varicose veins and six healthy subjects were enrolled. Structural and molecular changes of varices were assessed by immunohistochemical staining with anti-monocyte chemotactic protein-1 (MCP-1). MCP-1 and interleukin-6 (IL-6) levels in systemic antecubital blood were measured before and at 12 weeks after treatment. Results : Immunohistochemical staining revealed prominent manifestation of MCP-1-positive endothelial cells in the walls of varices. Preoperative serum MCP-1 and IL-6 levels in the patients were significantly higher than those in the control (166±12 pg/mL vs 99±10 pg/mL, p=0.003; 5.1±0.95 pg/mL vs 0.0±0.0 pg/mL, p=0.001, respectively). The values were significantly correlated with the severity of chronic venous insufficiency (CVI). Postoperative serum MCP-1 level significantly decreased compared with the preoperative level (152±10 pg/mL vs 166±12 pg/mL, p=0.048). The values after endovenous laser ablation did not significantly decrease compared with those after stripping. Conclusion : Varicose veins with CVI increase inflammatory biomarker levels in the local tissue and systemic blood. Appropriate treatment of symptomatic varicose veins decreases inflammatory biomarker levels., Competing Interests: Disclosure StatementWe have no conflict of interest to disclose., (Copyright © 2019 Annals of Vascular Diseases.)

Background: Unintentional renal artery occlusion after endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm remains one of the most unfavorable complications. Renal salvage options include percutaneous transluminal renal artery angioplasty (PTRA) and open hepatosplenorenal bypass. However, the usefulness of kidney autotransplantation (AutoTx) remains unclear., Case Presentation: A 76-year-old woman with a right solitary kidney attributable to a left renal thromboembolism had previously undergone EVAR with a stent graft for an infrarenal aortic aneurysm, which led to ostial occlusion of the right renal artery. In addition, she had undergone PTRA and stenting. Two days before admission, she developed leg edema and hypertension, leading her to visit the hospital. Her serum creatinine level was 2.4 (baseline, 1.0) mg/dL. Acute kidney injury due to renal artery in-stent restenosis was suspected; re-angioplasty was attempted on day 2 of hospitalization, but was unsuccessful. Her renal function did not improve and anuria persisted; thus, hemodialysis was initiated on the same day. The right kidney size (8.6 cm) was preserved relative to her body size, with only mild cortical atrophy. Doppler ultrasonography and mercaptoacetyltriglycine scintigraphy revealed minimal but significant perfusion of the right kidney. Therefore, we considered that kidney perfusion was sustained and renal function could be reversed. On day 25 of hospitalization, right kidney AutoTx to the right iliac fossa was performed to reestablish adequate renal perfusion and reverse the need for dialysis. Soon after the procedure, the patient started passing urine. Her renal function improved; her serum creatinine level decreased to 1.0 mg/dL on day 33 of hospitalization. Hemodialysis was discontinued after the surgery. Zero-hour kidney biopsy showed only mild tubular injury, with neither tubular necrosis nor glomerular abnormalities., Conclusions: Kidney AutoTx can be performed for patients with renal artery in-stent occlusion after unsuccessful PTRA who previously underwent EVAR. Our case showed successful recovery of renal function nearly 1 month after renal artery occlusion, indicating that revascularization should be considered even if it is delayed, as the kidney might be perfused through collateral circulation.

Background/aim: Nivolumab is an immune checkpoint inhibitor for advanced non-small cell lung cancer (NSCLC). We investigated the safety and efficacy of nivolumab by analyzing the response factor, adverse effects (AE), and the post-treatment condition of pretreated advanced or recurrent NSCLC patients., Patients and Methods: Nivolumab (3 mg/kg) was administered to 79 pre-treated NSCLC patients from December 2015 to January 2018. Nivolumab efficacy and AE were assessed using the Response Evaluation Criteria in Solid Tumors and the Common Terminology Criteria, respectively., Results: Progression-free survival (PFS) was significantly prolonged in cases where the therapeutic effect of the pretreatment was a partial response (p=0.0004). Five cases (6.3%) experienced grade 3-4 AEs. PFS was significantly prolonged in the skin rash group versus the non-skin rash group, and in patients where nivolumab treatment was discontinued., Conclusions: Long-term survival was observed in patients with skin rash. Therapeutic effect of nivolumab immediately following its administration appears to be favorable for survival., (Copyright© 2019, International Institute of Anticancer Research (Dr. George J.

Aim: Maternal obesity and improper nutrition predispose offspring to chronic metabolic diseases. Although the frequency of these diseases increases with aging, the effect of a maternal high-fat diet on aged offspring remains elusive., Main Methods: C57BL/6J female mice were fed a high-fat (HF) diet or a control (CON) diet and then mated. All offspring remained with their birth dam until weaning at 3 weeks. After weaning, the offspring from the HF and CON diet-fed dams were given either the HF diet or CON diet, which resulted in four groups: CON/CON, CON/HF, HF/CON, and HF/HF. All mice were immunized with ovalbumin and then sacrificed at 70 weeks., Key Findings: The body weights in offspring from dam exposed to a HF diet were significantly higher than those in offspring from dam fed a CON diet in the early stage of life but then became lower in the later stage of life. The serum adiponectin levels were lower in offspring from dam exposed to a HF diet and were correlated with adiposity measured by visceral and subcutaneous fat mass. Non-alcoholic fatty liver disease was much more severe in the livers of offspring from the maternal HF groups. In particular, lobular inflammation and fibrosis were prominent in the HF/HF group. Regarding immunological parameters, senescence-associated T cells were increased, and natural killer T cells were decreased by the effect of both maternal and offspring HF diet., Significance: We have demonstrated that a maternal high-fat diet may accelerate the adipo-immunologic aging process., (Copyright © 2019.

Protein S (PS) deficiency is an inherited thrombophilia associated with an increased risk of venous thromboembolism (VTE). In Japan, unfractionated heparin followed by warfarin has been historically applied for the treatment of VTE. Recent evidence showed that direct oral anticoagulants (DOACs) were non-inferior to standard therapy with warfarin, with significantly less bleeding in patients with VTE. However, it is unknown whether DOACs are effective for the treatment of VTE in patients with thrombophilia, including protein S deficiency, due to lack of evidence. Here, we report a case of recurrent venous thrombosis during edoxaban therapy in a patient with protein S deficiency, which was successfully treated using high-dose apixaban therapy. J.Med.

Maternal health and nutritional status influence offspring health and the diseases that may develop in them. The effects of maternal inflammation on offspring from the perspective of the inflammatory response and immune changes are not fully understood. We hypothesized that maternal inflammation modulates immune and metabolic functions, affecting the pathophysiology of inflammatory diseases in offspring. This study investigated whether maternal inflammation affects the onset of collagen-induced arthritis (CIA), a murine model of human rheumatoid arthritis. Female DBA/1J mice received a single intraperitoneal injection of lipopolysaccharide (LPS) 5 days before conception. Male offspring of LPS-treated dams were placed in the maternal LPS group (MLG). To induce CIA, type II collagen (CII) was emulsified with Freund's complete adjuvant and injected twice into each mouse, at 13 and 16 weeks. The offspring were sacrificed at 26 weeks to analyze immunological and metabolic parameters. The degree of joint swelling at an early stage of CIA was lower in the MLG than in the control group. From histological analysis, the severity of joint destruction (severity of arthritis score) and CII-specific IgG titer were significantly lower in the MLG. However, at 26 weeks, serum interleukin (IL)-6 levels, an index of CIA disease activity, were significantly higher in the MLG. Moreover, serum leptin levels were lower in the MLG, and a negative correlation between leptin and serum IL-6 was observed. In conclusion, maternal inflammation does not merely suppress inflammation; it may delay CIA in offspring. The analysis of inflammatory cytokines and leptin concentrations at 26 weeks suggests that the pathophysiology of arthritis was worsening. This study also suggests that maternal inflammation modulates postnatal inflammatory response patterns in offspring.

Pleurectomy/decortication (P/D) is the surgical treatment of choice for early malignant mesothelioma, but it remains unclear whether radiotherapy along with P/D should be used as multimodal treatment for this disease. We herein present the case of a 76-year-old man with a history of asbestos exposure who was diagnosed with left-sided malignant pleural mesothelioma in February 2010. The patient underwent chemotherapy with a combination of cisplatin and pemetrexed and achieved stable disease, after which time he was kept under observation. A positron emission tomography/computed tomography scan performed in February 2011 revealed nodular shadows with fluorodeoxyglucose uptake in S3 of the left lung; using bronchoscopy, the patient was diagnosed with stage IIB (cT3N0M0) primary squamous cell carcinoma. Chemoradiotherapy with vinorelbine and 60 Gy/20 fr radiotherapy was performed, and a partial response was obtained, suggesting that the radiotherapy used to treat the carcinoma of the lung may have also helped control the disease activity of the pre-existing mesothelioma. The present case indicates the value of radiotherapy in the treatment of malignant mesothelioma. The aim of the present study was to examine the possibility of new multimodal treatments for mesothelioma, along with a discussion of the relevant literature.

Background: Taxane/platinum (TP)-based combination chemotherapy is standard for the treatment of metastatic or recurrent cervical cancer. The aim of this study was to investigate the efficacy of postoperative TP therapy in early stage cervical cancer., Methods: A retrospective review of patients with FIGO IB-IIB stage cervical cancer who were treated with radical hysterectomy and displayed surgical-pathological risk factors was performed. 122 patients were identified between 2003 and 2012. Survival was analyzed by Kaplan-Meier method and compared by the log-rank test. The Cox proportional hazards model was used to investigate predictors of survival., Results: The median follow-up period was 82.4 months. The postoperative adjuvant therapy was TP in 82 (67.2%) patients, other chemotherapies in 10 (8.2%), radiotherapy (RT) in 25 (20.5%), and no further therapy (NFT) in 5 (4.1%). Survival was analyzed using 4 subgroups according to the postoperative adjuvant therapy. The estimated 5-year overall survival was 95.1% in the TP group, 90.0% in the other chemotherapy group, 78.9% in the RT group, and 100% in the NFT group. No significant difference of survival was observed in the subgroups. However, when analyzing only patients who displayed high-risk factors, non-TP adjuvant therapy (including RT and other chemotherapies) was independently associated with shorter survival on multivariate analysis. In the TP group, multivariate analysis revealed that a positive surgical margin was a significant predictor of shorter survival., Conclusions: Postoperative TP is effective in patients with surgically treated early stage cervical cancer. In these populations, a positive surgical margin could be associated with poor prognosis.
