However, current therapeutic options for corneal pain are limited. In this study, we synthesized a novel quaternary ammonium compound, N-propylamiodarone bromide (NPA), and employed a rodent model of corneal injury to investigate whether NPA offers prolonged corneal analgesia through transient receptor potential vanilloid 1 (TRPV1) channel-mediated selective cellular entry, without hindering corneal epithelial recovery.Methods: In the corneal injury model, 24 adult Wistar rats received a topical application of normal saline, oxybuprocaine, or NPA (n = 8 each), and corneal pain sensitivity was assessed using the von Frey technique. Another set of 32 rats with intact corneas received oxybuprocaine, capsaicin (a TRPV1 agonist), or NPA with or without capsaicin (n = 8 each), followed by a mechanical sensitivity evaluation. Potential adverse effects on normal epithelial recovery were evaluated using fluorescence and hematoxylin–eosin staining in an additional 8 rats with corneal injury.Results: In the corneal injury model, NPA produced significantly longer-lasting analgesia than oxybuprocaine (duration of the maximum effect: 215 ± 11 vs 25 ± 2 min, P < 0.001). None of the animals presented any signs of eye irritability. In contrast to injured eyes, NPA alone did not significantly increase mechanical sensitivity in naïve eyes. However, the co-administration of NPA and capsaicin produced significantly longer-lasting corneal anesthesia than oxybuprocaine (duration of the maximum effect: 165 ± 15 vs 31 ± 2 min, P < 0.001). NPA did not hamper wound healing.Conclusion: The novel quaternary ammonium NPA produced long-lasting analgesia against corneal injury without hampering corneal recovery, suggesting that it is a potential candidate for analgesic medicine targeting corneal pain.Keywords: analgesics, capsaicin, corneal injury, pain, TRPV1 channel

Few reports on raising headache awareness in the general public have been reported, and there are no reports on headache awareness campaigns through social networking services (SNS), or social media, in Japan. We prospectively performed a headache awareness campaign from March 2022 through 2 SNS, targeting nurse and wind instrumental musicians, because they are with high headache prevalence.Methods: Through the 2 SNS, the article and video were distributed, respectively. The article and video described the 6 important topics for the general public about headaches, which were described in the Clinical Practice Guideline for Headache Disorders 2021. Just after reading or watching them as e-learning, we performed online questionnaire sheets to investigate the awareness of the 6 topics through the 2 SNS. The awareness of the 6 topics before and after the campaign was evaluated.Results: In the SNS nurse-senka, we obtained 1191 responses. Women comprised 94.4%, and the median (range) age was 45 (20 to 71) years old. Headache sufferers were 63.8%, but only 35.1% had consulted doctors. In the SNS Creatone, we got the response from 134 professional musicians, with 77.3% of women. The largest number of respondents were in their 20s (range 18– 60 years old). Headache sufferers were 87.9%. Of them, 36.4% had consulted doctors, 24.2% were medication-overuse headache. The ratios of individuals who were aware of the 6 topics significantly increased from 15.2%-47.0% to 80.4– 98.7% after the online questionnaire in both SNS (p < 0.001, all).Conclusion: E-learning and online survey via SNS can improve headache awareness.Keywords: awareness, education, medication-overuse headache, migraine, online, prevention, social networking services, social media

Participants in this study were patients with glaucoma who were scheduled to receive any type of PGTFC for the first time. The participants answered a questionnaire on the day of PGTFC introduction and again at a return visit 4–6 weeks after PGTFC introduction. The physicians in charge were asked to complete a separate questionnaire on the day of PGTFC introduction. One of two leaflets was randomly delivered to each participant before the description of the PGTFC. One leaflet explained how to correctly instill the eye drops, and the other explained the clinical meaning of intraocular pressure reduction in addition to explaining how to correctly instill the eye drops. Nonadherence was defined as forgetting to instill the eye drops one or more times during the week before the return visit.Results: In total, 3,597 patients (age, 68.4±12.2 years) met the study protocol requirements. PGTFC introduction significantly reduced the number of antiglaucoma eye drops from 1.93±0.78 to 1.34±0.54 (P

The article presents the case study of a 68 year old woman with a history of Darier disease. She showed clinical and histological features of DD along with mild learning difficulties. The disease is an autosomal dominant genodermatosis as warty papules and plaques seborrhoeic areas, and neuropsychiatric abnormalities in some cases. DD is caused by mutations in the ATP2A2 gene, encoding the sarcoplasmic/endoplasmic reticulum.

Prcis: The genetic risk score (GRS) of genetic variants associated with intraocular pressure (IOP) elevation, but not those associated with optic nerve vulnerability, was associated with a history of glaucoma surgery in Japanese patients with primary open angle glaucoma (POAG)., Objective: To investigate genetic variants associated with a history of glaucoma surgery in Japanese patients with POAG., Methods: Japanese patients with POAG (n = 468), including normal tension glaucoma (n = 246) and high tension glaucoma (n = 222), and control subjects (n = 246) were genotyped for 22 genetic variants predisposing to POAG, which can be classified into those associated with IOP elevation (IOP-related genetic variants) and optic nerve vulnerability independent of IOP (optic nerve-related genetic variants). The unweighted and weighted GRSs of 17 IOP-related, 5 optic nerve-related, and all 22 genetic variants were calculated, and the association between the GRS and a history of glaucoma surgery was evaluated., Results: There was a significant association (odds ratio 1.13 per unweighted GRS, 95% CI: 1.03 to 1.24, P = 0.0093) between IOP-related unweighted GRS and a history of glaucoma surgery. A significant association (odds ratio 1.09 per 0.1 weighted GRS, 95% CI: 1.04 to 1.14, P = 0.00022) was also found between IOP-related weighted GRS and a history of glaucoma surgery. The IOP-related GRS was positively correlated with the need for glaucoma surgery. The mean of IOP-related unweighted and weighted GRS in patients with POAG with a history of glaucoma surgery were significantly higher ( P = 0.013 and P = 0.00031, respectively) than those in patients with POAG without a history of glaucoma surgery., Conclusions: IOP-related, but not optic nerve-related, genetic variants were associated with a history of glaucoma surgery in Japanese patients with POAG. These results indicate that IOP elevation induced by IOP-related genetic variants rather than optic nerve vulnerability induced by optic nerve-related genetic variants may play an important role in requiring glaucoma surgery., (Copyright © 2024 Wolters Kluwer Health, Inc.

Purpose: To evaluate the treatment outcomes of subthreshold micropulse laser (SMPL) with a wavelength of 670 nm (red) for treatment-naïve diabetic macular edema (DME)., Methods: A retrospective observational study which included 42 eyes in 34 patients diagnosed with treatment-naïve DME was conducted. Twenty-one eyes underwent red SMPL and the other 21 eyes underwent intravitreal injection of aflibercept (IVA) as initial treatment and were followed up for 12 months. Best-corrected visual acuity (BCVA), central retinal thickness (CRT) on optical coherence tomography (OCT), vessel density (VD), and foveal avascular zone area on OCT angiography (OCTA) were measured and compared between the two groups., Results: In the red SMPL group, the mean BCVA slightly improved from 0.29 ± 0.28 at baseline to 0.22 ± 0.29 at 12 months (p = 0.18), while the mean CRT significantly decreased from 472 ± 200 µm at baseline to 320 ± 136 µm at 12 months (p = 0.003). At 12 months from baseline, the mean change in BCVA and CRT were similar between the red SMPL and IVA groups (p = 0.79 and p = 0.31, respectively). No significant change was detected in OCTA parameters except for VD at the nasal section in the red SMPL group., Conclusion: Red SMPL for treatment-naïve DME maintained BCVA and significantly reduced CRT at 12 months. These treatment outcomes were equivalent to IVA in real-world settings, which tend to be inferior to clinical trials., (Copyright © 2024. Published by Elsevier B.V.)

Utilizing the unique properties of fluorine substitution is an effective strategy for constructing highly functional materials. Here, we synthesized a novel copolymer composed of [1.1.1]propellane and perfluoro(propyl vinyl ether) (PPVE), rich in alternating sequences. The spin-coated copolymer film was amorphous, and its surface exhibited an extremely low surface free energy (γ). The γ value was lower than that of polytetrafluoroethylene despite containing only 40 mol % PPVE units. This can be attributed to the cancellation of the C-F dipole moments by the entirely random orientation of the fluorine units.

Purpose: To investigate whether genetic and clinical characteristics differ depending on generations using 326 patients (male/female, 259/67; mean age, 55.4 ± 12.5 years) with simple CSC., Methods: All patients were diagnosed with simple CSC, defined as a retinal pigment epithelium alteration area equal to or smaller than 2-disc areas based on multimodal imaging at the initial presentation. We cross-sectionally evaluated clinical characteristics at the initial visit and genotyped CFH rs800292 and rs1329428 for all patients using TaqMan technology., Results: As generations decreased, the proportion of males, subfoveal choroidal thickness, and prevalence of fibrin significantly increased ( p  < 0.001, p  < 0.001, and p  = 0.012, respectively), and the best-corrected visual acuity improved ( p  < 0.001); in contrast, the prevalence of pachydrusen significantly decreased ( p  < 0.001). The younger presentation was significantly associated with male and risk variants (T allele) of CFH rs1329428 ( p  = 9.1 × 10 -7 and p  = 0.042, respectively), and patients were estimated to present 2 years younger per one T allele of CFH rs1329428 ( p  = 0.042, β = -1.95, stepwise regression analysis)., Conclusion: Clinical and genetic characteristics differed significantly among patients with simple CSC, depending on their generation.

Objective: We aimed to assess seasonal and age-related variations in sleep quality using Fitbit data and offer lifestyle recommendations for enhancing winter sleep quality. Methods: Fitbit sleep and activity data of 51 participants randomly recruited from members of the Association for Research in Supporting System of Chronic Disease, a nonprofit organization in the Yamanashi Prefecture of Japan, were collected and retrospectively analyzed from July to December 2022. Sleep stage targets were set at 10% to 25% for deep sleep, 50% to 60% for shallow sleep, and 20% to 25% for REM sleep. Participants were categorized into improved, unchanged, and worsened groups based on sleep stage unit changes between August and December. Results: The median (interquartile range) age was 71 (68-74) years old. There were eight participants in the improved group, 23 in the unchanged group, and nine in the worsened group. The improved group showed significantly more steps (990 ± 1,102 steps/day, p  = .039) in December than in August, while the worsened group showed fewer steps (-507 ± 1,638 steps/day, p  = .38). Conclusion: Increasing step count in winter may improve sleep quality, as assessed by sleep stage. Further research considering potential confounders and factors affecting winter sleep is needed to support and extend these findings., 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.)

Background: The copy number status (CNS) of the survival motor neuron (SMN) gene may influence the risk and prognosis of amyotrophic lateral sclerosis (ALS) and lower motor neuron diseases (LMND) other than spinal muscular atrophy (SMA). However, previous studies of this association, mainly from Europe, have yielded controversial results, suggesting possible regional differences. Here, we investigated the effect of the SMN gene in Japanese patients with ALS and LMND., Methods: We examined the SMN copy numbers and clinical histories of 487 Japanese patients with sporadic ALS (281 men; mean age at onset 61.5 years), 50 with adult LMND (50 men; mean age at onset 58.4 years) and 399 Japanese controls (171 men; mean age 62.2 years). Patients with pathogenic mutations in ALS-causing genes were excluded. SMN1 and SMN2 copy numbers were determined using the droplet digital polymerase chain reaction., Results: The frequency of a copy number of one for the SMN2 gene was higher in patients with ALS (38.0%) than in healthy controls (30.8%) (odds ratio (OR) = 1.37, 95% confidence interval (CI) = 1.04-1.82, p < 0.05). The SMN2 copy number affected the survival time of patients with ALS (median time: 0 copies, 34 months; 1 copy, 39 months; 2 copies, 44 months; 3 copies, 54 months; log-rank test, p < 0.05). Cox regression analysis revealed that the SMN2 copy number was associated with increased mortality (hazard ratio = 0.84, 95% CI = 0.72-0.98, p < 0.05). Also, null SMN2 cases were significantly more frequent in the LMND group (12.0%) than in the control group (4.8%) (OR = 2.73, 95% CI = 1.06-6.98, p < 0.05)., Conclusions: Our findings suggest that SMN2 copy number reduction may adversely affect the onset and prognosis of MND, including ALS and LMND, in Japanese., (© 2024.

Background and study aims The duodenum and colorectum are target organs for familial colorectal adenomatous polyposis, however, the association of duodenal epithelial tumors (DETs) and colorectal tumors is still controversial. The aim of our study was to elucidate the association between DET and colorectal tumor. Patients and methods This was an exploratory cross-sectional study of patients with DETs treated by endoscopic resection at our hospital, between November 2018 and October 2022. Individuals who underwent colonoscopy as part of the health screening comprised the reference control group for comparison. In both groups, lesions suspected of being tumors were resected. The main outcome was the adenoma detection rate (ADR). Other outcomes were the detection rate for advanced neoplasia (AN) and risk factors for colorectal adenoma and AN, evaluated using univariate and multivariable analyses. Results Analyses were based on data from 163 individuals in the DET group and 177 in the control group. ADR was higher in the DET (63.2%) than in the control (23.6%) group ( P < 0.001). AN and invasive cancer rates were also significantly higher in the DET than in the control group (AN: 20.9% vs 3.4%, respectively, P < 0.001; invasive cancer: 3.1% vs 0%, respectively, P < 0.001). On logistic regression analysis, DET was found to be associated with a 5-fold increase in the detection rate of adenoma and 6-fold increase in AN detection. Conclusions The study revealed significant association between DET and high ADR and a higher frequency of AN and invasive cancer. Screening colonoscopy is suggested for patients with DETs., Competing Interests: Conflict of Interest The authors declare that they have no conflict of interest., (The Author(s).

Eukaryotic translation initiation factor (eIF)4A-a DEAD-box RNA-binding protein-plays an essential role in translation initiation. Recent reports have suggested helicase-dependent and helicase-independent functions for eIF4A, but the multifaceted roles of eIF4A have not been fully explored. Here we show that eIF4A1 enhances translational repression during the inhibition of mechanistic target of rapamycin complex 1 (mTORC1), an essential kinase complex controlling cell proliferation. RNA pulldown followed by sequencing revealed that eIF4A1 preferentially binds to mRNAs containing terminal oligopyrimidine (TOP) motifs, whose translation is rapidly repressed upon mTORC1 inhibition. This selective interaction depends on a La-related RNA-binding protein, LARP1. Ribosome profiling revealed that deletion of EIF4A1 attenuated the translational repression of TOP mRNAs upon mTORC1 inactivation. Moreover, eIF4A1 increases the interaction between TOP mRNAs and LARP1 and, thus, ensures stronger translational repression upon mTORC1 inhibition. Our data show the multimodality of eIF4A1 in modulating protein synthesis through an inhibitory binding partner and provide a unique example of the repressive role of a universal translational activator., (© 2024.

Aim: To develop an artificial intelligence (AI) algorithm that diagnoses cataracts/corneal diseases from multiple conditions using smartphone images., Methods: This study included 6442 images that were captured using a slit-lamp microscope (6106 images) and smartphone (336 images). An AI algorithm was developed based on slit-lamp images to differentiate 36 major diseases (cataracts and corneal diseases) into 9 categories. To validate the AI model, smartphone images were used for the testing dataset. We evaluated AI performance that included sensitivity, specificity and receiver operating characteristic (ROC) curve for the diagnosis and triage of the diseases., Results: The AI algorithm achieved an area under the ROC curve of 0.998 (95% CI, 0.992 to 0.999) for normal eyes, 0.986 (95% CI, 0.978 to 0.997) for infectious keratitis, 0.960 (95% CI, 0.925 to 0.994) for immunological keratitis, 0.987 (95% CI, 0.978 to 0.996) for cornea scars, 0.997 (95% CI, 0.992 to 1.000) for ocular surface tumours, 0.993 (95% CI, 0.984 to 1.000) for corneal deposits, 1.000 (95% CI, 1.000 to 1.000) for acute angle-closure glaucoma, 0.992 (95% CI, 0.985 to 0.999) for cataracts and 0.993 (95% CI, 0.985 to 1.000) for bullous keratopathy. The triage of referral suggestion using the smartphone images exhibited high performance, in which the sensitivity and specificity were 1.00 (95% CI, 0.478 to 1.00) and 1.00 (95% CI, 0.976 to 1.000) for 'urgent', 0.867 (95% CI, 0.683 to 0.962) and 1.00 (95% CI, 0.971 to 1.000) for 'semi-urgent', 0.853 (95% CI, 0.689 to 0.950) and 0.983 (95% CI, 0.942 to 0.998) for 'routine' and 1.00 (95% CI, 0.958 to 1.00) and 0.896 (95% CI, 0.797 to 0.957) for 'observation', respectively., Conclusions: The AI system achieved promising performance in the diagnosis of cataracts and corneal diseases., Competing Interests: Competing interests: TY: Grants (Novartis Pharma); honoraria for lectures (Alcon Japan, HOYA, Novartis Pharma, AMO Japan, Santen Pharmaceuticals, Senju Pharmaceutical, Johnson & Johnson), MM: Grants (Novartis Pharma); honoraria for lectures (Bayer Yakuhin, Kowa Pharmaceutical, Alcon Japan, HOYA, Novartis Pharma, AMO Japan, Santen Pharmaceutical, Senju Pharmaceutical, Johnson & Johnson K.K., Japan Ophthalmic Instruments Association).

Aim: We determined the number of care transitions in the year before death among older adults requiring long-term care (LTC) and those receiving public LTC insurance (LTCI) services in Japan, along with care transition pathways and factors associated with the number of care transitions., Methods: This study used data from the Japanese LTCI claims, which store national information on certification of needed LTC and LTCI claims data. Services received in the year before death were classified as in-home, facility, mixture of in-home and facility, and not using LTCI services. The transition count is presented, and Sankey diagrams are produced to visualize care transition pathways. We used a multivariable analysis to identify factors associated with the number of care transitions., Results: Of the participants, 276 896 (65.2%) experienced at least one transition in LTCI care settings in the year before death. Further, 72.0% of those requiring mild LTC underwent one or more transitions. Participants who were 75-84 years old (vs. 65-74 years old), male, without medical care needs, with symptoms of dementia, and with changes in LTC needs in the year before death were more likely to require care transitions. Moreover, participants with higher baseline LTC needs were less likely to require transitions., Conclusion: Over half the participants requiring LTC underwent one or more care transitions in the year before death. Policy deliberations regarding enhancing care under the LTCI system at the end of life and optimizing care transitions are necessary. Geriatr Gerontol Int 2024; 24: 883-890., (© 2024 The Author(s).

Paget disease of the breast is a malignant tumor that occurs primarily on the skin of the nipple, whereas extramammary Paget disease occurs on the skin in regions other than the breast, such as the pubis, perianal area, and axilla. Paget disease can also arise outside these areas; this is referred to as ectopic extramammary Paget disease. In this study, we present a case of a Japanese woman in her 70s who experienced simultaneous occurrence of two ectopic extramammary Paget disease lesions on the skin of the anterior chest and left buttock. Both lesions, exceeding 5 cm in diameter, were surgically excised, and the histopathological examination led to a diagnosis of ectopic extramammary Paget disease without invasion. To the best of our knowledge, this is the third reported case of multiple simultaneous ectopic extramammary Paget disease. Clinically, diagnosis of a patient with ectopic extramammary Paget disease is challenging because of its unusual location; however, the disease may be considered a differential diagnosis for Bowen disease., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background: Transabdominal ultrasonography and transperineal ultrasonography (TPUS) appear correspond to colonoscopy (CS) for evaluating ulcerative colitis (UC) activity, but their utility in UC diagnosis remains unclear. This research compared the accuracy of TPUS and CS for assessing rectal activity and differentiating noninflammatory bowel disease proctitis from UC in pediatric cases., Methods: The study is a blinded, prospective, and controlled trial. Prospectively, values of fecal calprotectin (FCP) and findings of the TPUS and CS were compared between child cases of UC and non-IBD proctitis. Findings of rectal wall thickening (RWT), rectal wall flow (RWF) on power Doppler, and microvascular signal at wall circumference (MSWC) on monochrome superb microvascular imaging assessed using TPUS were compared with the CS., Results: Thirty patients with Mayo endoscopic subscore (MES) 0 to 1 UC, 57 with MES 2 to 3 UC, and 44 with proctitis were registered. Fecal calprotectin, RWF, and MSWC indicated significant differences among the groups (P < .05). Rectal wall thickening showed no significant difference between MES 0-1 and proctitis (P = .76). Rectal wall thickening and MSWC were independent predictors of endoscopic activity of UC, resulting in a sensitivity and specificity of 100% for RWT ≥4.5 mm and positive MSWC. Fecal calprotectin and RWF were independent predictors for differentiating MES 0 to 1 and proctitis, and FCP and RWT were independent predictors for differentiating MES 2 to 3 and proctitis. Sensitivity and specificity were 77.2% and 80.9%, respectively, for FCP >242.5 μg/g and RWF negative; and they were both 100% for RWT >4.1 mm and MSWC positive., Conclusions: Transperineal ultrasonography with mSMI may enable the evaluation of rectal activity and differentiation of UC from non-IBD proctitis with accuracy comparable to endoscopy., (© The Author(s) 2023.

We report the familial occurrence of a severe phenotype of central serous chorioretinopathy (CSC). A 62-year-old man was referred to our institute to treat a macular lesion in his right eye. Best-corrected visual acuity (BCVA) in his right eye was 0.05 (decimal format). On the initial visit, swept-source optical coherence tomography (SS-OCT) demonstrated subretinal hyperreflective material (SHRM) and subretinal fluid involving the central macula in the right eye and a descending tract on fundus autofluorescence (FAF) in the left eye, and fluorescein angiography revealed focal leakage corresponding to choroidal vascular hyperpermeability (CVH) on indocyanine green angiography (ICGA) of the right eye. He received photodynamic therapy (PDT) for the right eye and exudation disappeared. His 66-year-old elder brother had a medical history of CSC in both eyes and had received treatment at our hospital at 61 years old. On the initial presentation, ICGA showed multiple CVH in both eyes, and FAF showed hypofluorescence corresponding to retinal pigment epithelium (RPE) tears and RPE atrophy in both eyes. Bullous retinal detachment (RD) developed inferiorly in both eyes, and a vitrectomy was performed for the right eye to repair RD. The baseline BCVA was 0.3 in both eyes. Two years after the initial visit, recurrent serous RD developed in his left eye, and multiple PDT sessions were performed during the six-year follow-up. A severe phenotype of CSC may be associated with a genetic background., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Purpose: We compared 12-month outcomes of eyes with polypoidal choroidal vasculopathy (PCV) with or without complete regression of polyps observed one month after three monthly intravitreal administrations (loading phase) of aflibercept (2.0 mg/0.05 mL) or brolucizumab (6.0 mg/0.05 mL)., Methods: All patients underwent indocyanine green angiography at both baseline and 3 months after initial injection and were followed up monthly with an as-needed regimen for up to 12 months. A total of 62 patients with PCV were included: 30 eyes were treated with brolucizumab, and 32 were treated with aflibercept. Eyes with complete regression of polyps (regression group) had significantly smaller maximum polyp diameter and were more frequently treated with brolucizumab than those without complete regression (non-regression) group., Results: Best corrected visual acuity was comparable between the two groups at 12 months. Although the 12-month retreatment-free proportion was comparable between the two groups (33.0% versus 27.0%, p = 0.59), a retreatment-free period was significantly longer in the regression group than in the non-regression group (8.3 ± 3.3 versus 6.5 ± 3.6 months, p = 0.022), and the number of additional injections was significantly fewer in the regression group than in the non-regression group (1.2 ± 1.2 versus 3.0 ± 2.6, p = 0.007)., Conclusions: Complete regression of polyps observed after the initial phase possibly prolongs the retreatment-free period and reduces the number of additional injections irrespective of aflibercept or brolucizumab.

Objectives: In April 2012, the Japanese government launched a new nursing service called the nursing small-scale multifunctional home care (NSMHC) to meet the nursing care demands of individuals with moderate-to-severe activities of daily living (ADLs) dysfunction and who require medical care, thereby allowing them to continue living in the community. We aimed to preliminarily analyse the characteristics of first-time users of NSMHC service., Design: This pooled cross-sectional study used the Japanese long-term care insurance (LTCI) claims data from the users' first use of NSMHC (from April 2012 to December 2019)., Setting: NSMHC includes nursing home visits, home care, daycare, overnight stays and medical treatment., Participants: The study population included LTCI beneficiaries who received their first long-term care requirement certification in Japan from April 2012 onwards, died between April 2012 and December 2019, and used any LTCI service at least once., Results: Among the 836 563 individuals who used any LTCI service at least once, 3957 (0.47%) used NSMHC. We analysed 3634 individuals without any missing data regarding long-term care requirement certification. Most individuals were aged 80 years or older, with 64.3% requiring care level 3 or above, indicating complete assistance with ADLs. Regarding ADLs in individuals with dementia, 70.6% were at level 2 or below, indicating they can live almost independently even with dementia. A large proportion of NSMHC users availed the service approximately 6 months before death, with no prior use of any LTCI services; they continued using the service for around 4 months, although some people continued to use NSMHC until their month of death., Conclusions: Using individual data on nationwide LTCI, we described the characteristics of first-time users of NSMHC among those who died within 7.5 years from the first certification of care needs. Further studies are needed to investigate the effect of NSMHC use on user outcomes., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Poor sleep quality can elevate stress levels and diminish overall well-being. Japanese individuals often experience sleep deprivation, and workers have high levels of stress. Nevertheless, research examining the connection between objective sleep assessments and stress levels, as well as overall well-being, among Japanese workers is lacking., Objective: This study aims to investigate the correlation between physiological data, including sleep duration and heart rate variability (HRV), objectively measured through wearable devices, and 3 states (sleepiness, mood, and energy) assessed through ecological momentary assessment (EMA) and use of rating scales for stress and well-being., Methods: A total of 40 office workers (female, 20/40, 50%; mean age 40.4 years, SD 11.8 years) participated in the study. Participants were asked to wear a wearable wristband device for 8 consecutive weeks. EMA regarding sleepiness, mood, and energy levels was conducted via email messages sent by participants 4 times daily, with each session spaced 3 hours apart. This assessment occurred on 8 designated days within the 8-week timeframe. Participants' stress levels and perception of well-being were assessed using respective self-rating questionnaires. Subsequently, participants were categorized into quartiles based on their stress and well-being scores, and the sleep patterns and HRV indices recorded by the Fitbit Inspire 2 were compared among these groups. The Mann-Whitney U test was used to assess differences between the quartiles, with adjustments made for multiple comparisons using the Bonferroni correction. Furthermore, EMA results and the sleep and HRV indices were subjected to multilevel analysis for a comprehensive evaluation., Results: The EMA achieved a total response rate of 87.3%, while the Fitbit Inspire 2 wear rate reached 88.0%. When participants were grouped based on quartiles of well-being and stress-related scores, significant differences emerged. Specifically, individuals in the lowest stress quartile or highest subjective satisfaction quartile retired to bed earlier (P<.001 and P=.01, respectively), whereas those in the highest stress quartile exhibited greater variation in the midpoint of sleep (P<.001). A multilevel analysis unveiled notable relationships: intraindividual variability analysis indicated that higher energy levels were associated with lower deviation of heart rate during sleep on the preceding day (β=-.12, P<.001), and decreased sleepiness was observed on days following longer sleep durations (β=-.10, P<.001). Furthermore, interindividual variability analysis revealed that individuals with earlier midpoints of sleep tended to exhibit higher energy levels (β=-.26, P=.04)., Conclusions: Increased sleep variabilities, characterized by unstable bedtime or midpoint of sleep, were correlated with elevated stress levels and diminished well-being. Conversely, improved sleep indices (eg, lower heart rate during sleep and earlier average bedtime) were associated with heightened daytime energy levels. Further research with a larger sample size using these methodologies, particularly focusing on specific phenomena such as social jet lag, has the potential to yield valuable insights., Trial Registration: UMIN-CTR UMIN000046858; https://center6.umin.ac.jp/cgi-open-bin/ctr/ctr&#95;view.cgi?recptno=R000053392., (©Shotaro Kinoshita, Sayaka Hanashiro, Shiori Tsutsumi, Kiko Shiga, Momoko Kitazawa, Yasuyo Wada, Jun Inaishi, Kazuhiro Kashiwagi, Toshikazu Fukami, Yasumasa Mashimo, Kazumichi Minato, Taishiro Kishimoto.

Purpose: To compare the genetic and clinical characteristics of central serous chorioretinopathy (CSC) in patients with and without steroid use., Methods: A total of 407 consecutive patients with CSC were included. Demographic data and clinical factors, including subfoveal choroidal thickness, bilateral involvement, descending tracts, pachydrusen, fibrin, and dome-shaped pigment epithelial detachment, were obtained. Variants of complement factor H (CFH)   I62V (rs800292) and rs1329428 were genotyped in all cases using TaqMan technology., Results: Of the total patients, 48 (11.8%) were steroid users. The majority of males were non-steroid users (82.5%) than steroid users (58.3%) (p = 9.8 × 10 -5 ). Demographic data and the prevalence of clinical factors were comparable between the two groups (all p-values > 0.10). Risk allele frequencies of CFH rs800292 and rs1329428 were also comparable between the two groups (p = 0.76, rs800292: steroid users = 52.1% vs. non-steroid users = 50.4%; p = 0.62, rs1329428: steroid users = 47.9% vs. non-steroid users = 45.3%)., Conclusions: Except for the male/female ratio, there were no significant differences in the clinical presentation or genetic characteristics, including variants of the CFH gene, between the two groups., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Yoneyama et al.)
