Eosinophilic granulomatosis with polyangiitis (EGPA) poses a significant diagnostic challenge due to its varied clinical presentation. Here, we present a case of a 59-year-old female with a history of asthma and sinusitis, who manifested with an extremely rare presentation of drastic tense blisters and hemorrhagic bullae alongside purpuric lesions and peripheral neuropathy. Examinations revealed eosinophilia, positive anti-neutrophil cytoplasmic antibody, and characteristic pathological findings with small vessel vasculitis in the purpura. Treatment with glucocorticoids and cyclophosphamide led to rapid improvement in peripheral eosinophilia, skin manifestations and motor neuron deficits. Although rare, our case underscores that bullous skin lesions should be recognized as a potential cutaneous hallmark of EGPA to aid timely diagnosis, since prompt treatment initiation is crucial given the potential irreversible organ damage and poor prognosis of EGPA., (© Japan College of Rheumatology 2024.

The usefulness of the derived neutrophil-to-lymphocyte ratio (dNLR) and its dynamics before/after durvalumab consolidation therapy to predict safety or efficacy remains unclear. We retrospectively reviewed patients with locally advanced non-small cell lung cancer treated with durvalumab consolidation therapy after chemoradiotherapy (D group) or chemoradiotherapy alone (non-D group) at multiple institutions. We investigated the association between dNLR, or its dynamics, and pneumonitis, checkpoint inhibitor-related pneumonitis (CIP), irAEs, and efficacy. Ninety-eight and fifty-six patients were enrolled in the D and non-D groups, respectively. The dNLR at baseline was significantly lower in patients who experienced irAEs or CIP than in those who did not. The low dNLR group, 28 days following durvalumab consolidation therapy (dNLR28 ≤ 3), demonstrated longer progression-free survival (PFS) and overall survival (OS) than the high dNLR group (dNLR28 > 3) (PFS, hazard ratio [HR] 0.44, 95% confidence interval [CI] 0.22-0.88, p = 0.020; OS, HR 0.39, 95% CI 0.16-0.94, p = 0.037). Among patients with high dNLR at baseline (dNLR > 3), the dNLR28 ≤ 3 group showed longer PFS than the dNLR28 > 3 group (p = 0.010). The dNLR is a predictive factor for irAEs and CIP in patients receiving durvalumab consolidation therapy. The dNLR at 28 days after durvalumab consolidation therapy and its dynamics predict favorable outcomes., (© 2024. The Author(s).)

Dual-task performance holds significant relevance in real-world scenarios. Implicit learning is a possible approach for improving dual-task performance. Analogy learning, utilizing a single metaphor to convey essential information about motor skills, has emerged as a practical method for fostering implicit learning. However, evidence supporting the effect of implicit learning on gait-cognitive dual-task performance is insufficient. This exploratory study aimed to examine the effects of implicit and explicit learning on dual-task performance in both gait and cognitive tasks. Tandem gait was employed on a treadmill to assess motor function, whereas serial seven subtraction tasks were used to gauge cognitive performance. Thirty healthy community-dwelling older individuals were randomly assigned to implicit or explicit learning groups. Each group learned the tandem gait task according to their individual learning styles. The implicit learning group showed a significant improvement in gait performance under the dual-task condition compared with the explicit learning group. Furthermore, the implicit learning group exhibited improved dual-task interference for both tasks. Our findings suggest that implicit learning may offer greater advantages than explicit learning in acquiring autonomous motor skills. Future research is needed to uncover the mechanisms underlying implicit learning and to harness its potential for gait-cognitive dual-task performance in clinical settings., (© 2024. The Author(s).)

Few studies have quantified longitudinal changes in swallowing in patients undergoing esophagectomy for esophageal cancer. This study longitudinally analyzed the changes in the Modified Barium Swallow Study Impairment Profile (MBSImP™) scores, swallowing kinematic measurements, and swallowing-related symptoms in patients undergoing esophagectomy. We also examined the association between identified swallowing impairment and aspiration pneumonia after surgery. We included consecutive patients who underwent esophagectomy and completed laryngoscopy and videofluoroscopy before, two weeks, and three months after surgery. We analyzed physiological impairments using the MBSImP. We also assessed the swallowing kinematics on a 5 mL thickened liquid bolus at three time points. Vocal fold mobility was assessed using a laryngoscope. Repeated measures were statistically examined for longitudinal changes in swallowing function. The association between the significant changes identified after esophagectomy and aspiration pneumonia was tested. Twenty-nine patients were included in this study. Preoperative swallowing function was intact in all participants. The timing of swallowing initiation and opening of the pharyngoesophageal segment remained unchanged after surgery. Tongue base retraction and pharyngeal constriction ratio worsened two weeks after surgery but returned to baseline levels three months after surgery. Three months after surgery, hyoid displacement and vocal fold immobility did not fully recover. Aspiration pneumonia occurred in nine patients after surgery and was associated with postoperative MBSImP pharyngeal residue scores. Decreased hyoid displacement and vocal fold immobility were observed postoperatively and persisted for a long time. The postoperative pharyngeal residue was associated with pneumonia and thus should be appropriately managed after surgery., (© 2023. The Author(s).)

Background/purpose: The long-term clinical impact of prostate position-based image-guided radiotherapy (IGRT) for localized prostate cancer remains unclear., Materials and Methods: We retrospectively compared clinical outcomes following intensity-modulated radiation therapy (IMRT) with cone-beam computed tomography-based prostate position-based IGRT (P-IGRT) or without P-IGRT (non-P-IGRT). From June 2011, we applied P-IGRT in IMRT for intermediate-risk (IR) prostate cancer (PCa) (D'Amico risk classification) (76 Gy in 38 fractions, with smaller margins). Clinical outcomes of patients who received P-IGRT between June 2011 and June 2019 were retrospectively compared with those of patients with IR PCa who received IMRT without P-IGRT between October 2002 and May 2011 in our institution (74 Gy in 37 fractions)., Results: A total of 222 consecutive patients were analyzed: 114 in the P-IGRT cohort and 108 in the non-P-IGRT cohort. The median follow-up period after IMRT was 7.1 years for the P-IGRT cohort and 10.8 years for the non-P-IGRT cohort. The biochemical failure-free rate was significantly better in the P-IGRT cohort (94.9% for the P-IGRT cohort vs 82.7% for the non-P-IGRT cohort at 10 years, p = 0.041). The rate of rectal bleeding which needs intervention including the use of suppositories was significantly lower in the P-IGRT cohort (p < 0.001)., Conclusions: The use of P-IGRT with higher doses and smaller margins was correlated with significantly better biochemical control, and a lower incidence of rectal bleeding in IMRT for intermediate-risk prostate cancer. The enhanced accuracy using P-IGRT has the potential to independently improve disease control and reduce late rectal bleeding., (© 2024.

Introduction: Stroke is a major cause of disability and mortality worldwide and requires long-term care, including rehabilitation. This study aims to elucidate the association between care-need levels after discharge and long-term outcomes in patients with stroke., Methods: We used a Japanese administrative database that covers both medical and long-term care insurance systems to retrospectively identify 7491 patients who underwent acute-phase in-hospital rehabilitation for stroke between June 2014 and February 2019. We investigated the association between nationally standardized care-need levels (support levels 1-2 and care-need levels 1-3) 6 months after discharge and long-term outcomes. Using the Fine-Gray model, we conducted multivariable survival analysis with adjustment for patient backgrounds and treatment courses to estimate hazard ratios (HR) for mortality and the incidence of being bedridden., Results: The median age was 82 (interquartile range [IQR], 76-87) years, 5418 patients (72%) had cerebral infarction, and 4009 patients (54%) had partial dependence after discharge. During a median follow-up of 580 (IQR, 189-925) days, 1668 patients (22%) became bedridden, and 2174 patients (29%) died. Compared with patients with support level 1, those with higher care-need levels showed significantly higher proportions of being bedridden-the subdistribution HR [95% confidence interval] were 1.52 [1.10-2.12], 2.85 [2.09-3.88], and 3.79 [2.79-5.15] in those with care-need levels 1, 2, and 3, respectively. Higher care-need levels were also significantly associated with higher mortality., Conclusions: This large-scale observational study demonstrated that a higher level of care-need after discharge was significantly associated with poorer functional outcomes and higher mortality., Competing Interests: Takaaki Konishi received grants from Pfizer Co.
