Abstract
BACKGROUND Childhood-onset glomerular disease often requires ongoing treatment and follow-up into adulthood. However, few studies have analyzed the associated impact and distress experienced by patients with this condition during the transition from childhood to adolescence and adulthood. METHODS At three facilities, we recruited patients who developed idiopathic nephrotic syndrome or IgA nephropathy during childhood and were at least 18 years old at the time of study entry. Among them, a questionnaire-based survey was administered to patients who consented to participate, and the results were analyzed in conjunction with clinical information. RESULTS Data from a total of 38 patients were analyzed. Of these patients, 15 had idiopathic nephrotic syndrome and 23 had IgA nephropathy. The age of transition from pediatrics to the adult medicine department was correlated with the number of recurrences. Many patients also reported being significantly affected by exercise restrictions and physical decline associated with their diseases and medications. Various impacts, including distress, affected decision-making regarding higher education, with patients engaging in higher education at a significantly higher rate compared with the regional average (66.7% vs. 46.9%, p = 0.028). CONCLUSION We analyzed the impact of childhood-onset glomerular disease and distress during the transition period from pediatric to adult care. This study highlighted the significant impact of medications and exercise restrictions on patients' decisions regarding higher education. Future prospective studies will be needed to examine patients' distress in more detail and establish management approaches to enhance patient quality of life.

Abstract
Visual information is processed in hierarchically organized parallel streams in the primate brain. In the present study, information segregation in parallel streams was examined by constructing a convolutional neural network with parallel architecture in all of the convolutional layers. Although filter weights for convolution were initially set to random values, color information was segregated from shape information in most model instances after training. Deletion of the color-related stream decreased recognition accuracy of animate images, whereas deletion of the shape-related stream decreased recognition accuracy of both animate and inanimate images. The results suggest that properties of filters and functions of a stream are spontaneously segregated in parallel streams of neural networks.

Abstract
Key clinical message Pseudohypoaldosteronism (PHA) carries a good prognosis if treated early and appropriately, but some cases can have life-threatening events. We underscored the need to consider secondary PHA as one of the differential diagnoses of hyponatremia and hyperkalemia in infancy. Abstract Pseudohypoaldosteronism (PHA) type 1 has two classifications; the primary type, caused by genetic abnormalities that develop during neonatal and infancy periods, and the secondary type, caused by urinary tract malformation and urinary tract infection. Secondary PHA, if treated early and appropriately, has a good prognosis; however, some cases can present life-threatening events. Therefore, early diagnosis is crucial. We present a case of early infancy secondary PHA presented with marked hyponatremia and poor weight gain. The patient's growth and development improved with secondary PHA treatment. Here, were demonstrated the value of prompt action against infection and electrolyte imbalance and the importance of imaging for diagnosis, and underscore the need to consider secondary PHA as a differential diagnoses of hyponatremia and hyperkalemia in infancy. However further studies, including basic research, to elucidate the diseases pathology is warranted.

Abstract
This retrospective treatment-planning study was conducted to determine whether intensity-modulated proton therapy with robust optimization (ro-IMPT) reduces the risk of acute hematologic toxicity (H-T) and acute and late gastrointestinal toxicity (GI-T) in postoperative whole pelvic radiotherapy for gynecologic malignancies when compared with three-dimensional conformal radiation therapy (3D-CRT), intensity-modulated X-ray (IMXT) and single-field optimization proton beam (SFO-PBT) therapies. All plans were created for 13 gynecologic-malignancy patients. The prescribed dose was 45 GyE in 25 fractions for 95% planning target volume in 3D-CRT, IMXT and SFO-PBT plans and for 99% clinical target volume (CTV) in ro-IMPT plans. The normal tissue complication probability (NTCP) of each toxicity was used as an in silico surrogate marker. Median estimated NTCP values for acute H-T and acute and late GI-T were 0.20, 0.94 and 0.58 × 10-1 in 3D-CRT; 0.19, 0.65 and 0.24 × 10-1 in IMXT; 0.04, 0.74 and 0.19 × 10-1 in SFO-PBT; and 0.06, 0.66 and 0.15 × 10-1 in ro-IMPT, respectively. Compared with 3D-CRT and IMXT plans, the ro-IMPT plan demonstrated significant reduction in acute H-T and late GI-T. The risk of acute GI-T in ro-IMPT plan is equivalent with IMXT plan. The ro-IMPT plan demonstrated potential clinical benefits for reducing the risk of acute H-T and late GI-T in the treatment of gynecologic malignances by reducing the dose to the bone marrow and bowel bag while maintaining adequate dose coverage to the CTV. Our results indicated that ro-IMPT may reduce acute H-T and late GI-T risk with potentially improving outcomes for postoperative gynecologic-malignancy patients with concurrent chemotherapy.

Abstract
Purpose We aimed to describe the epidemiology of angioid streaks (AS) and pseudoxanthoma elasticum (PXE), which are rare diseases, using a national claims database. Design This was a population-based longitudinal cohort study. Participants A total of 126 million individuals were covered by the universal health coverage system in Japan. Methods With permission from the Ministry of Health, Labor and Welfare, we accessed all data from the National Database of Health Insurance Claims and Specific Health Checkups of Japan, which contains the nationwide health insurance claims data for 126 million Japanese. We identified individuals with AS and PXE between January 2011 and December 2020. The incidence rates, prevalence, overlap of AS and PXE, and mean age at death were calculated. Main Outcome Measures The incidence rates and prevalence of AS and PXE. Results A total of 6598 cases of AS and 1020 cases of PXE were identified during the 10-year study period. The incidence rates of AS and PXE were 0.52 (95% confidence interval, 0.48-0.56) and 0.08 (95% confidence interval, 0.07-0.10) per 100 000 person-years, respectively. On October 1, 2020, the prevalence of AS and PXE was 6.5 (95% confidence interval, 6.38-6.66) and 0.83 (95% confidence interval, 0.78-0.89) per 100 000 persons, respectively. The overlap of AS and PXE was 363 patients. The mean age at death of individuals with AS and PXE was 79.3 ± 0.51 and 77.1 ± 2.68 years, respectively. Conclusion This is the first population-based study to elucidate the epidemiology of AS and PXE. The mean age of death of both AS and PXE patients was younger than the mean life expectancy of the general Japanese population, thus, appropriate diagnosis and management are important to avoid preventable death.

Abstract
Purpose To evaluate the efficacy and safety of faricimab injections for treatment-naïve neovascular age-related macular degeneration (nvAMD) patients, including subtypes and pachychoroid phenotypes, and identify predictive factors for visual outcomes. Methods nvAMD patients were prospectively recruited, receiving three monthly faricimab (6 mg) injections. Best-corrected visual acuity (BCVA) two months after the last injection (month 4) was compared between subtypes, and between pachychoroid neovasculopathy (PNV) and non-PNV eyes. Regression analysis determined factors influencing month 4 BCVA. Results The study involved 23 patients (12 typical AMD [tAMD], 10 polypoidal choroidal vasculopathy [PCV], 1 retinal angiomatous proliferation [RAP]). Eleven exhibited PNV phenotype. Significant BCVA (P = 4.9 × 10-4) and central retinal thickness (CRT) (P = 1.3 × 10-5) improvements were observed post-faricimab treatment. The therapy demonstrated favourable results for both tAMD and PCV eyes, and non-PNV and PNV eyes. Faricimab achieved dry macula in 77.3% of eyes, with subretinal fluid resolution in most cases, although intraretinal fluid (IRF) often persisted. Multivariable analysis identified external limiting membrane (ELM) presence and IRF as BCVA contributors at month 4. Conclusion Faricimab demonstrated significant effectiveness and safety in treatment-naïve nvAMD patients, particularly for PCV and PNV eyes. ELM presence and IRF is predictive of visual outcomes.

Abstract
PURPOSE To investigate the predictors of macular chorioretinal atrophy, consisting of patchy atrophy (PA) at the macula and choroidal neovascularization (CNV)-related macular atrophy (CNV-MA), during treatment with ranibizumab or aflibercept for myopic CNV (mCNV) and its impact on visual outcomes. METHODS This retrospective study included 82 eyes with treatment-naïve mCNV who were treated with pro re nata injections of ranibizumab or aflibercept. RESULTS Nine eyes (11.0%) presented with macular PA at baseline (PA group), and 73 eyes (89.0%) did not (non-PA group). VA improved during the first year in the non-PA group; a similar trend was noted in the PA group until 3 months after initial treatment. This improvement was maintained until 24 months ( P < 0.001) in the non-PA group, but not in the PA group. In the PA group, macular chorioretinal atrophy progressed faster ( P < 0.0001), and CNV-MA was more frequent during the 2 years of treatments ( P = 0.04). Even non-PA group eyes sometimes developed CNV-MA (42% at Month 24) if they had a larger CNV and thinner subfoveal choroidal thickness at baseline, resulting in poorer visual prognosis ( P < 0.01). CONCLUSION Macular PA at baseline was a risk factor for CNV-MA development and was associated with poor visual outcomes.

Abstract
This study aimed to analyze the trends and factors influencing the number of ophthalmic surgeries in Japan using the open data from the National Database of Health Insurance Claims and Specific Health Checkups of Japan published by the Ministry of Health, Labour and Welfare. We calculated the number of cataract, glaucoma, and vitreoretinal surgeries, categorized by sex, age, and surgical type, for the fiscal years (FY) 2014 to 2020. The number of cataract surgeries remained stable at approximately 1.45 million cases from FY 2014 to 2018, increased to nearly 1.6 million cases in FY 2019, and decreased to 1.45 million cases in FY 2020. Among glaucoma surgeries, surgical treatments were increased 1.8 times over 7 years, from 33,000 to 60,000 cases. Laser treatment remained steady at around 55,000 cases from FY 2014 to 2017 and then increased to approximately 60,000 cases. The number of vitreoretinal surgeries was increased 1.2 times from FY 2014 to 2019, from 120,000 to 140,000, and decreased to 130,000 by FY 2020. Trends in ophthalmic surgeries over the past 7 years may be influenced by population aging, minimally invasive surgery, and the coronavirus disease pandemic. These findings have implications on surgical decision-making and resource allocation.

Abstract
Though vascular endothelial growth factors (VEGF) and other proangiogenic factors, such as angiopoietins (Ang), may be involved in the development of neovascular age-related macular degeneration (nvAMD), only drugs that inhibit the VEGF family are available for the treatment. The newly approved anti-VEGF drug faricimab, which also inhibits Ang-2, is expected to be effective in patients with AMD refractory to conventional anti-VEGF drugs. Therefore, we prospectively investigated the efficacy of faricimab in the treatment of aflibercept-refractory nvAMD. Patients with nvAMD who had been treated with aflibercept in the last year and required bimonthly injections were recruited. 25 eyes showed persistent exudative changes immediately before the faricimab injection (baseline). In these 25 eyes, switching to faricimab did not change visual acuity or central retinal thickness 2 months after the injection; however, 56% of eyes showed reduction or complete absorption of fluid. Notably, 25% of the eyes that showed dry macula at month 2 had no fluid recurrence for up to 4 months. These results indicate that faricimab could benefit some patients with aflibercept-refractory nvAMD.

Abstract
PURPOSE To investigate the prevalence and incidence of strabismus in the Japanese population by age group and to estimate the subtype proportions. DESIGN A nationwide population-based cohort study METHODS: This study investigated the number of cases with previous and new diagnoses of strabismus by age group between 2009 and 2020 using the National Database of Health Insurance Claims and Specific Health Checkups of Japan, which includes almost all (≥95%) medical claims data. We calculated the strabismus prevalence and 1-year incidence in 2019 and analyzed the proportion of each strabismus subtype. RESULTS The strabismus prevalence was 2.154% (2,709,207/125,708,000; 95% confidence interval, 2.152-2.157%). It showed a bimodal distribution, with high proportion in school and old ages (especially ≥75 years). Exotropia, esotropia, and cyclovertical strabismus proportions were 67.3%, 23.9%, and 6.7%, respectively. Cyclovertical strabismus was uncommon in patients aged ≤18 years (1.4%) and more common (10.2%) in those aged >18 years. The strabismus incidence in 2019 was 321 per 100,000 person-years (403,093/125,708,000; 95% confidence interval, 320 to 322). The annual incidence proportion of cyclovertical strabismus as opposed to whole strabismus subtypes in patients aged >18 years (13.1%) was higher than that in those aged ≤18 years (1.4%). CONCLUSIONS This is the first nationwide population-based cohort study to demonstrate strabismus's overall prevalence and incidence. The high prevalence of cyclovertical strabismus in adults compared with children may suggest that cyclovertical strabismus is a primarily age-related strabismus. The high prevalence of exotropia may indicate a genetic difference between Japanese and other ethnicities.

Abstract
PURPOSE To investigate factors associated with 3-month or 1-year best-corrected visual acuity (BCVA) after vitrectomy with subretinal tissue plasminogen activator injection for submacular hemorrhage (SMH) and to identify the predictors of early displacement. METHODS This prospective cohort study included consecutive eyes with SMH complicating neovascular age-related macular degeneration or retinal macroaneurysm that underwent vitrectomy with subretinal tissue plasminogen activator injection and were followed up for at least 3 months. Parameters that correlated with 3-month BCVA, 1-year BCVA, and 2-week displacement grade (0-3) were identified. RESULTS Twenty-nine eyes of 29 patients (73.1 ± 8.4 years; neovascular age-related macular degeneration, 25 eyes) were included. Logarithm of the minimum angle of resolution BCVA improved 3 months after the surgery (baseline, 0.76 [20/115] ± 0.35; 3-month, 0.51 [20/65] ± 0.32; P = 0.006). In multivariable analyses, 1-year logarithm of the minimum angle of resolution BCVA correlated with age ( P = 0.007, β = 0.39) and SMH recurrence within 1 year after surgery ( P < 0.001, β = 0.65). Two-week displacement grade correlated with the contrast-to-noise ratio of SMH ( P = 0.001, β = -0.54). Macular hole occurred in three eyes (10%) with small SMH size and was closed in all eyes via additional vitrectomy with an inverted internal limiting membrane flap technique. CONCLUSION The recurrence of SMH negatively affected the 1-year visual outcome after vitrectomy with subretinal tissue plasminogen activator injection for SMH. The contrast-to-noise ratio was a useful predictor of early SMH displacement, but not of 1-year BCVA. Further research is necessary to determine the optimal treatment to prevent SMH recurrence.

Abstract
PURPOSE To investigate the 10-year visual outcome and chorioretinal atrophy after a single intravitreal ranibizumab injection followed by a pro re nata regimen for myopic macular neovascularization in pathologic myopia, and to identify the factors associated with 10-year best-corrected visual acuity (BCVA). METHODS This retrospective observational study evaluated 26 consecutive treatment-naïve eyes (26 patients) with myopic macular neovascularization in pathologic myopia who underwent a single intravitreal ranibizumab followed by a pro re nata regimen of intravitreal ranibizumab and/or intravitreal aflibercept injection and observed over 10 years. We assessed changes in BCVA and morphological parameters, including the META-PM Study category as a chorioretinal atrophy index. RESULTS The logarithm of the minimum angle of resolution BCVA changed from 0.36 (Snellen, 20/45) ± 0.39 to 0.39 (20/49) ± 0.36 over 10 years of observation. Compared to baseline, 1-year BCVA improved ( P = 0.002), whereas 2 to 10-year BCVA was not significantly different. Total injection frequency was 3.8 ± 2.6. In none of the eyes, 10-year BCVA was 20/200 or less. Ten-year BCVA correlated with baseline BCVA ( P = 0.01, r = 0.47). The META-PM Study category progressed in 60% of eyes. There were no drug-induced complications. CONCLUSION Best-corrected visual acuity in eyes with myopic macular neovascularization in pathologic myopia was maintained for 10 years after a single intravitreal ranibizumab followed by a pro re nata regimen without drug-induced complications. The META-PM Study category progressed in 60% of eyes, especially those with older baseline age. Early diagnosis and treatment of myopic macular neovascularization are essential to maintain good long-term BCVA.

Abstract
During free viewing, we move our eyes and fixate on objects to recognize the visual scene of our surroundings. To investigate the neural representation of objects in this process, we studied individual and population neuronal activity in three different visual regions of the brains of macaque monkeys (Macaca fuscata): the primary and secondary visual cortices (V1, V2) and the inferotemporal cortex (IT). We designed a task where the animal freely selected objects in a stimulus image to fixate on while we examined the relationship between spiking activity, the order of fixations, and the fixated objects. We found that activity changed across repeated fixations on the same object in all three recorded areas, with observed reductions in firing rates. Furthermore, the responses of individual neurons became sparser and more selective with individual objects. The population activity for individual objects also became distinct. These results suggest that visual neurons respond dynamically to repeated input stimuli through a smaller number of spikes, thereby allowing for discrimination between individual objects with smaller energy.

Abstract
Background Spinal metastasis pain includes both inflammatory and neuropathic pain, and opioids, which have only a μ-opioid receptor-stimulating effect, are generally less effective in neuropathic pain. However, no previous study has been conducted for the comparisons of the efficacy of opioids in treating spinal metastasis pain. Objective To compare the efficacy of tapentadol and methadone with other opioids for back pain caused by a metastatic spinal tumor. Design Retrospective cohort study. Setting/Subjects A total of 274 patients were enrolled, who started a tapentadol extended-release tablet, methadone tablet, hydromorphone extended-release tablet, oxycodone extended-release tablet, or transdermal fentanyl patch for cancer pain due to spinal metastasis in Japan from January 1, 2013 to October 31, 2021. Measurements The primary endpoint, the difference in the numerical rating scale (NRS) scores before and seven days after each opioid administration, was compared among the five groups. Results In patients with numbness, a decrease of the NRS score on day seven compared with before starting each opioid was significantly higher in the tapentadol group than those in the hydromorphone, oxycodone, and fentanyl groups and comparable to that in the methadone group. In patients without numbness, no significant differences were observed in decreases of the NRS scores on day seven among the five groups. Conclusions Tapentadol and methadone may be more effective than hydromorphone, oxycodone, and fentanyl for cancer pain due to spinal metastasis with numbness.

Abstract
Purpose To examine choroidal angiographic features in the posterior pole associated with resolution or persistency of subretinal fluid (SRF) in eyes with central serous chorioretinopathy (CSC). Design Observational case series. Methods Twenty-nine patients with treatment-naïve CSC were divided into two groups based on the presence or absence of SRF 3 months after the initial visit (month 3) without any treatment. Using enhanced depth imaging of widefield swept-source optical coherence tomography, the choroidal thickness (CT), vessel density (VD), and vessel diameter index (VDI) in the superotemporal and inferotemporal subfields on the temporal side of the 18-mm circle from the disc were measured at the initial visit. We calculated the vertical difference in CT and other choroidal angiographic parameters and evaluated their association with the SRF condition at 3 months. Results The SRF-resolved and SRF-persistent groups included 10 and 19 patients, respectively. At the initial visit, sex, age, axial length, symptom duration, the logarithm of the minimum angle of resolution visual acuity, and foveal thickness were not significantly different between the two groups. The SRF status at month 3 was not associated with the vertical difference in CT and choroidal VD (P = .614, .065, respectively). However, the vertical difference in choroidal VDI was positively associated with the future presence of SRF (P = .017). Conclusions Vertically asymmetric dilation of choroidal vessels in the posterior pole may be a vasculature feature associated with SRF from CSC and may be a good predictor of future SRF status.

Abstract
Novel wound dressing materials are required to non-cytotoxic with a viable cell ratio of above 92%. Herein, the cytotoxicity of hyaluronic acid/chitosan/bacterial cellulose-based (BC(CS/HA)) membranes are evaluated and compared to that of alginate/chitosan/bacterial cellulose-based (BC(CS/Alg)) membranes was investigated. Multilayer membranes with up to ten CS/HA or CS/Alg layers were prepared using the layer-by-layer (LBL) method. Scanning electron microscopy showed that the diameters of the fibers in the BC(CS/Alg) and BC(CS/HA) membranes were larger than those in a BC membrane. The cytotoxicity was analyzed using BALB-3T3 clone A31 cells (mouse fibroblasts, 1 × 104 cells/well). The BC(CS/HA)5 and BC(CS/HA)10 membranes exhibited high biocompatibility, with the cell viabilities of 94% and 87% at 5 d, respectively, compared to just 82% for the BC(CS/Alg)5 and BC(CS/Alg)10 membranes with same numbers of layers. These results suggested that BC(CS/HA)5 is a promising material for wound dressings.

Abstract
We examined the effect of reduced fluence (rf)-photodynamic therapy (PDT) of the macular area on the wide-field choroidal thickness in 20 eyes with central serous chorioretinopathy (CSC) and 20 age- and sex-matched control eyes. The choroidal thickness at the posterior pole was measured before and after rf-PDT, using a grid with inner and outer rings, each divided into superotemporal, inferotemporal, superonasal, and inferonasal quadrants, respectively, making up a total of nine subfields including the central 3 mm ring. Before treatment, all eyes showed wide-field choroidal thickening from the dilated vortex vein ampulla to the fovea, along the course of the vein. After rf-PDT of the macular area, the choroidal thickness significantly decreased, not only in the irradiated macular area but also outside the arcade vessels in all quadrants (p < 0.001 for all inner subfields; p = 0.035 and p = 0.024 for the outer superonasal and inferonasal subfields, respectively; p < 0.001 and p = 0.004 for the outer superotemporal and inferotemporal subfields, respectively). For control eyes, the choroidal thickness did not differ between the initial visit and follow-up 1.2 ± 0.7 months after the initial visit (p > 0.05 for all subfields). These findings provide new insights into the pathogenesis of CSC and explain the reasons for the effectiveness of rf-PDT for this condition.

Abstract
The relationship between IgA nephropathy (IgAN) and Crohn’s disease was reported. IgAN is the most common primary glomerulonephritis and one of the leading causes of chronic kidney disease and end-stage renal failure, and up to 50% of cases progressed to end-stage renal disease within 25 years after IgAN diagnosis. However, specific and effective therapeutic strategies are still lacking. In this review, we discuss the possibility of the mechanism involved in IgAN associated with Crohn’s disease based on the findings of basic and clinical studies. Although the etiology of IgAN associated with Crohn’s disease is not permanent and various factors are thought to be involved, the stabilization of the disease condition of Crohn’s disease is believed to help treat IgAN.

Abstract
Key Clinical Message Although percutaneous renal biopsy is considered safe, this invasive procedure has complications such as renal arteriovenous fistula (RAVF). Even if complications such as RAVFs are not observed early after renal biopsy, considering the possibility of delayed renal hemorrhage, follow-up with ultrasound after renal biopsy even in asymptomatic cases could be important. Abstract Although percutaneous renal biopsy is considered safe, this invasive procedure can lead to complications such as renal arteriovenous fistula (RAVF). RAVF occurs when some arteries and veins communicate in the absence of capillaries in the renal hilum or renal parenchyma. It was previously thought to be relatively rare; however, with advances in imaging diagnostics, it is sometimes found asymptomatically. In addition, renal biopsy is the most common cause of acquired RAVF. In this case, RAVF was discovered 2 years after renal biopsy. Late-onset RAVF is scarce. This case highlights that even if complications such as RAVFs are not observed early after renal biopsy, considering the possibility of delayed RAVF, follow-up with ultrasound could be important.

Abstract
In this study, nonwoven gelatin (Gel) fabrics crosslinked using N-acetyl-D-glucosamine (GlcNAc) were characterized and compared with those crosslinked using methylglyoxal (MG) and by thermal dehydration. We prepared Gel with 25% concentration along with Gel/GlcNAc and Gel/MG with a GlcNAc-to-Gel ratio of 5% and MG-to-Gel ratio of 0.6%. A high voltage of 23 kV, solution temperature of 45 °C, and distance of 10 cm between the tip and the collector were applied during electrospinning. The electrospun Gel fabrics were crosslinked by heat treatment at 140 and 150 °C for 1 d. The electrospun Gel/GlcNAc fabrics were treated at 100 and 150 °C for 2 d, while the Gel/MG fabrics were heat-treated for 1 d. The Gel/MG fabrics exhibited higher tensile strength and lower elongation than the Gel/GlcNAc fabrics. Overall, Gel/MG crosslinked at 150 °C for 1 d showed a significant enhancement in tensile strength, high hydrolytic degradation, and excellent biocompatibility, with cell viability percentages of 105 and 130% at 1 and 3 d, respectively. Therefore, MG is a promising Gel crosslinker.

Abstract
BACKGROUND There are two known types of exercise-induced acute renal failure. One is the long-known myoglobinuria-induced acute renal failure due to severe rhabdomyolysis, and the other is the recently recognized non-myoglobinuria-induced acute renal failure with mild rhabdomyolysis. Exercise-induced acute renal failure was first reported in 1982. Non-myoglobinuria-induced acute renal failure is associated with severe low back pain and patchy renal vasoconstriction, and it is termed post-exercise acute renal failure because it usually occurs hours after exercise. It is also called acute renal failure with severe loin pain and patchy renal ischemia after anaerobic exercise (ALPE).
AIM To makes a significant contribution to medical literature as it presents a study that investigated a not-widely-known type of exercise-induced acute renal failure known as ALPE.
METHODS We performed a database search selecting papers published in the English or Japanese language. A database search was lastly accessed on September 1, 2022. The results of this study were compared with those reported in other case series.
RESULTS The study evaluated renal hypouricemia as a key risk factor of ALPE. The development of ALPE is due to the sum of risk factors such as exercise, hypouricemia, nonsteroidal anti-inflammatory drugs, vasopressors, and dehydration.
CONCLUSION In conclusion, hypouricemia plays a key role in the development of ALPE and is often associated with anaerobic exercise. The development of ALPE is a result of the cumulative effects of risk factors such as exercise, hypouricemia, NSAIDs, vasopressors, and dehydration.

Abstract
Herein, improving the antibacterial activity of a hydrogel system of sodium alginate (SA) and basic chitosan (CS) using sodium hydrogen carbonate by adding AgNPs was investigated. SA-coated AgNPs produced by ascorbic acid or microwave heating were evaluated for their antimicrobial activity. Unlike ascorbic acid, the microwave-assisted method produced uniform and stable SA-AgNPs with an optimal reaction time of 8 min. Transmission electron microscopy (TEM) confirmed the formation of SA-AgNPs with an average particle size of 9 ± 2 nm. Moreover, UV-vis spectroscopy confirmed the optimal conditions for SA-AgNP synthesis (0.5% SA, 50 mM AgNO3, and pH 9 at 80 °C). Fourier transform infrared (FTIR) spectroscopy confirmed that the -COO- group of SA electrostatically interacted with either the Ag+ or -NH3+ of CS. Adding glucono-δ-lactone (GDL) to the mixture of SA-AgNPs/CS resulted in a low pH (below the pKa of CS). An SA-AgNPs/CS gel was formed successfully and retained its shape. This hydrogel exhibited 25 ± 2 mm and 21 ± 1 mm inhibition zones against E. coli and B. subtilis and showed low cytotoxicity. Additionally, the SA-AgNP/CS gel showed higher mechanical strength than SA/CS gels, possibly due to the higher crosslink density. In this work, a novel antibacterial hydrogel system was synthesized via 8 min of microwave heating.

Abstract
PURPOSE To investigate predictors for macular atrophy (MA) involving the fovea after photodynamic therapy (PDT) followed by pro re nata (PRN) treatment for polypoidal choroidal vasculopathy (PCV). METHODS This prospective observational study analysed treatment-naïve eyes with symptomatic PCV without MA at baseline which were followed up for 5 years. All eyes were initially treated with PDT, followed by a PRN regimen of anti-vascular endothelial growth factor (VEGF) therapy and/or PDT. We assigned eyes with and eyes without development of MA involving the fovea 5 years after the initial treatment into MA and non-MA groups, respectively. Baseline parameters and the number of treatments were compared between the two groups. RESULTS Seventy-two eyes of 69 consecutive patients were included, and 29 eyes of 29 patients were analysed. Twelve (41%) and 17 (59%) eyes were assigned into the MA and non-MA groups, respectively. There were significant differences in subfoveal choroidal thickness (226.2 ± 47.8 μm vs. 278.8 ± 68.1 μm, P = 0.03) and number of anti-VEGF injections (13.7 ± 9.6 vs. 5.4 ± 5.6, P = 0.007) between the MA and non-MA groups, but not in the number of PDT sessions (P = 0.71). Best-corrected visual acuity at 5 years in the MA group was lower than in the non-MA group (P = 0.048). CONCLUSION Our long-term observation suggests that a thin subfoveal choroid at baseline and many followed anti-VEGF injections in a PRN regimen increase the risk for development of MA involving the fovea 5 years after PDT.

Abstract
BACKGROUND This study evaluated safety, reactogenicity, and immunogenicity of a 2-month homologous booster regimen of Ad26.COV2.S in Japanese adults. METHODS In this multicenter, placebo-controlled, Phase 1 trial, adults (Cohort 1, aged 20-55 years, N = 125; Cohort 2, aged ≥ 65 years, N = 125) were randomized 2:2:1 to receive Ad26.COV2.S 5 × 1010 viral particles (vp), Ad26.COV2.S 1 × 1011 vp, or placebo, followed by a homologous booster 56 days later. Safety, reactogenicity, and immunogenicity were assessed. RESULTS Two hundred participants received Ad26.COV2.S and 50 received placebo. The most frequent solicited local adverse event (AE) was vaccination-site pain, and the most frequent solicited systemic AEs were fatigue, myalgia, and headache. After primary vaccination, neutralizing and binding antibody levels increased through Day 57 (post-prime) in both cohorts. Fourteen days after boosting (Day 71), neutralizing antibody geometric mean titers (GMTs) had almost reached their peak value in Cohort 1 (5 × 1010 vp: GMT = 1049; 1 × 1011 vp: GMT = 1470) and peaked in Cohort 2 (504; 651); at Day 85, GMTs had declined minimally in Cohort 2. For both cohorts, binding antibody levels peaked at Day 71 with minimal decline at Day 85. CONCLUSION A single dose and homologous Ad26.COV2.S booster increased antibody responses with an acceptable safety profile in Japanese adults (ClinicalTrials.gov Identifier: NCT04509947).

Abstract
PURPOSE To evaluate the association between the duration of macular detachment (DMD) and visual prognosis in patients with macula-off rhegmatogenous retinal detachment (RD). DESIGN Prospective observational cohort study. PARTICIPANTS This study analyzed 719 eyes with macula-off rhegmatogenous RD registered with the Japan-Retinal Detachment Registry created by the Japan Retina and Vitreous Society. METHODS We included patients with macular detachment without a history of prior surgery, except cataract surgery and vitrectomy. Reoperation cases, hereditary RD, and macular hole RD were excluded. We compared the visual prognosis between patients with DMD of N days or less and those with DMD of N + 1 days or more (N = 2-5). For these 4 comparisons, the inverse probability of treatment weighting (IPTW) methodology was employed, to balance 20 baseline characteristics between the shorter and longer DMD groups. The baseline characteristics included age, sex, axial length, baseline visual acuity, operative procedures, and detailed characteristics of RD. P-values < 0.01 were considered statistically significant. MAIN OUTCOME MEASURES The best-corrected visual acuity (BCVA) 6 months after surgery. RESULTS The final analysis included 719 eyes. For all comparisons, the patients' backgrounds were well balanced after IPTW with standardized differences < 0.10. The IPTW regression analysis revealed that the BCVA after 6 months was significantly better after surgeries for DMD of ≤ 2 days than that for DMD of ≥ 3 days. Similarly, the 6-month BCVA for surgeries for DMD of ≤ 3 days was significantly better than that for surgeries for DMD of ≥ 4 days (differences in logarithm of the minimum angle of resolution: -0.113, P = 9.1 × 10-7; -0.076, P = 1.6 × 10-3, respectively). On the other hand, there were no statistically significant differences for the other comparisons. CONCLUSIONS Earlier surgical treatment within 3 days from the onset of macular detachment should be considered, after accounting for social circumstances, such as weekends.

Abstract
Segmentation of a natural scene into objects (figures) and background (ground) is one of crucial functions for object recognition and scene understanding. Recent studies have investigated neural mechanisms underlying figure-ground (FG) segregation and reported neural modulation to FG in the intermediate-level visual area, V4, of macaque monkeys (FG neurons). However, whether FG neurons contribute to the perception of FG segregation has not been clarified. To examine the contribution of FG neurons, we examined the correlations between perceptual consistency (PC), which quantified perceptual ambiguity in FG determination, and the reliability of neural signals in response to FG. First, we evaluated PCs for the images that were used in the previous neural recording in V4; specifically, we measured how consistently FG can be determined across trials and participants for each stimulus. The PCs were widely distributed, so that we identified the ambiguity in FG segregation for each stimulus. Next, we analyzed the correlation between the PCs and the reliability of neural modulation to FG. We found that the stimuli with higher PCs evoked more consistent and greater modulation in the responses of single neurons than those with lower PCs. Since perception is expected to show a greater correlation with responses of neural population compared to those of single neurons, we examined the correlation between the PCs and the consistency of the population responses in FG determination. Stimuli with higher PCs evoked higher population consistency than those with lower PCs. Finally, we analyzed the correlation between the PCs and neural latencies in FG modulation. We found that the stimuli with higher PCs showed shorter reaction times in FG perception and evoked shorter modulation latencies in FG neurons. These results indicate that the responses of FG neurons recorded from macaque monkeys show significant correlations with human FG perception, suggesting that V4 neurons with FG-dependent responses contribute to the perception of FG segregation.

Abstract
The European Society of Cardiology recommends the 0/1-hour algorithm for risk stratification of patients with suspected non-ST-elevation myocardial infarction as class I, level B; however, there are few reports on the long-term prognosis, resulting in a rule-out group. We aimed to determine whether implementation of the 0-hour/1-hour algorithm is safe and effective in emergency department (ED) patients with possible acute coronary syndrome (ACS) through a 1-year follow-up period. Our study analyzed the 1-year follow-up data from a prospective pre-post study of 1106 ED patients with possible ACS from 4 hospitals in Japan and Taiwan. Patients were 18 years or older. Accrual occurred for 1 year after implementing the 0-1-hour algorithm from November 2014 to December 2018. Overall, 520 patients were stratified into the rule-out group. Major advanced cardiovascular events (all-cause death, acute myocardial infarction [AMI], stroke, unstable angina, and revascularization) at 1-year were determined using data from health records and phone calls. The 0-1-hour algorithm stratified 47.0% of patients in the rule-out group. Over the 1-year follow-up period (follow-up rate = 86.9%), cardiovascular death and subsequent AMI did not occur in the rule-out group. Among the 27 patients who underwent the procedure within 30 days post-index visit, 3 patients (0.7%) had a stroke, 6 patients (1.3%) died of non-cardiovascular cause, and 30 patients (6.7%) underwent coronary revascularization within 1 year. At the 1-year follow-up, implementation of the 0-hour/1-hour algorithm was associated with very low rates of adverse event among patients in the rule-out group.

Abstract
Congenital nephrogenic diabetes insipidus (CNDI), a rare hereditary disorder, is characterized by the inability of the kidneys to concentrate urine in response to the antidiuretic hormone arginine vasopressin (AVP); as a result, large volumes of unconcentrated urine are excreted. In addition to the clinical manifestations of CNDI, such as dehydration and electrolyte disturbances (hypernatremia and hyperchloremia), developmental delay can result without prompt treatment. In approximately 90% of cases, CNDI is an X-linked disease caused by mutations in the arginine vasopressin receptor 2 (AVPR2) gene. In approximately 9% of cases, CNDI is an autosomal recessive disease caused by mutations in the water channel protein aquaporin 2 (AQP2), and 1% of cases are autosomal dominant. We report a case of CNDI caused by a novel AVPR2 nonsense mutation, c.520C>T (p.Q174X), and cases of siblings in another family who had a different AVPR2 nonsense mutation, c.852G>A (p.W284X). Both cases responded well to treatment with hydrochlorothiazide and spironolactone. If CNDI is suspected, especially in carriers and neonates, aggressive genetic testing and early treatment may alleviate growth disorders and prevent irreversible central nervous system disorders and developmental delay.

Abstract
A waiting list for non-emergency transplant medical care was recommended in the first half of 2020 due to the coronavirus disease 2019 (COVID-19) pandemic. Hence, the number of kidney transplants temporarily declined. However, the waiting list for transplant medical care was lifted in the latter half of 2020 with the establishment of a polymerase chain reaction test system and the spread of infection prevention. The basic stance is to recommend vaccination to post-transplant recipients, recipients, and donors who are scheduled to undergo transplantation, and their families, with the start of vaccine therapy in 2021. The mortality rate of patients undergoing kidney transplants who had COVID-19 is slightly higher than healthy persons, and acute kidney injury was reported to lead to graft loss. However, pediatric cases of severe disease are rare and without deaths. Kidney transplantation medical care will be continuously provided by implementing infection prevention and treatments based on the latest evidence, promoting donated kidney transplantation, and hoping that pediatric patients with renal failure will grow up healthy, both physically and mentally, and become independent members of society, just like healthy children.

Abstract
PURPOSE To investigate the natural course of pachychoroid pigment epitheliopathy (PPE). DESIGN A retrospective cohort study. SUBJECTS From the Kyoto central serous chorioretinopathy (CSC) cohort consisting of 548 patients with CSC as of September 2020, we included consecutive unilateral patients with acute or chronic CSC between January 2013 and December 2016. METHODS All patients underwent complete ophthalmic examination, including multimodal imaging such as fundus autofluorescence, spectral-domain optical coherence tomography, and fluorescein angiography/indocyanine green angiography and/or optimal coherence tomography angiography. The fellow eyes of eyes diagnosed with CSC were screened for PPE, and their natural course was evaluated. We also evaluated the association of ARMS2 rs10490924, CFH rs800292, TNFRSF10A rs13278062, and GATA5 rs6061548 genotypes with the natural course. MAIN OUTCOME MEASURES Incidence of CSC, pachychoroid neovasculopathy, and pachychoroid geographic atrophy (GA). RESULTS In total, 165 patients with unilateral CSC (mean age, 55.7 ± 12.6 years; female, 22.4%) were included from the Kyoto CSC cohort. Among them, 148 (89.7%) were diagnosed as having PPE in their non-CSC eye. Survival analysis revealed that 16.8% of PPE eyes developed CSC during the 6-year follow up, whereas non-PPE eyes did not. Although genetic factors did not have significant association with CSC development (P > 0.05, log-rank test), choroidal vascular hyperpermeability (CVH) and subfoveal choroidal thickness (SFCT) were significantly associated with CSC incidence (P = 0.001, log-rank test). Survival analysis showed that eyes without CVH and eyes with SFCT < 300 μm did not develop CSC during the 6-year follow-up. Pachychoroid neovasculopathy developed in only 1 eye with PPE during a follow-up of 46.4 months. Pachychoroid GA did not develop in any of the studied eyes. CONCLUSIONS This study revealed a natural history of PPE in a relatively large Japanese cohort. Choroidal vascular hyperpermeability and SFCT were significant risk factors for the development of CSC in PPE eyes. Although the current results cannot be generalized for all eyes with PPE, these findings present an important clinical implication.

Abstract
Abstract
Background
Membranoproliferative glomerulonephritis (MPGN), a rare glomerulonephritis that causes nephrotic syndrome in children, is often difficult to treat. Typical immunofluorescence findings include strong C3 staining in a granular pattern along the glomerular capillary wall and negative IgA staining. IgA-dominant MPGN without hypocomplementemia has been reported. Herein, we report a rare case of MPGN with hypocomplementemia and predominant IgA subclass 2 deposits.
Case presentation
An 11-year-old girl showed proteinuria on a school urinalysis screening and presented with upper eyelid edema. The urinalysis showed elevated urinary protein levels and hematuria. Laboratory examinations revealed the following: serum albumin, 1.3 g/dL; serum creatinine, 0.54 mg/dL; and C3c, 67 mg/dL (normal range: 73–138 mg/dL). The physical and laboratory findings did not suggest autoimmune diseases. A renal biopsy was then performed. Specimen examination under a light microscope showed mesangial cell proliferation, increased mesangial matrix with lobulation, and some double contours of the glomerular basement membrane in almost all glomeruli, which are characteristic findings of MPGN. Immunofluorescent studies showed IgA deposits not only in the mesangial regions but also along the capillary walls, which were more strongly stained than C3. IgA subclass staining showed a stronger immunoreactivity for IgA2 than IgA1. Electron microscopic studies showed electron-dense deposits in the subendothelial, subepithelial, and paramesangial regions. Based on these findings, the patient was diagnosed with IgA-dominant MPGN. Accordingly, she was treated with three courses of methylprednisolone pulse therapy (MPT), followed by prednisolone, mizoribine, and lisinopril. Although hypocomplementemia improved after three courses of MPT, nephrotic-range proteinuria and hypoalbuminemia remained; therefore, two courses of MPT were additionally administered, and the immunosuppressant was changed from mizoribine to cyclosporine (CsA). Finally, the urinary protein level decreased, and a subsequent renal biopsy, two years later, showed improvement in the lesions.
Conclusions
We report an atypical case of MPGN with IgA2 dominant deposits along the glomerular capillary wall and in the mesangial region. The case was refractory to standard therapy but sensitive to CsA, which resulted in remission. Our findings suggest that CsA may be useful as an immunosuppressant to treat refractory MPGN.

Abstract
Analysis and understanding of trained deep neural networks (DNNs) can deepen our understanding of the visual mechanisms involved in primate visual perception. However, due to the limited availability of neural activity data recorded from various cortical areas, the correspondence between the characteristics of artificial and biological neural responses for visually recognizing objects remains unclear at the layer level of DNNs. In the current study, we investigated the relationships between the artificial representations in each layer of a trained AlexNet model (based on a DNN) for object classification and the neural representations in various levels of visual cortices such as the primary visual (V1), intermediate visual (V4), and inferior temporal cortices. Furthermore, we analyzed the profiles of the artificial representations at a single channel level for each layer of the AlexNet model. We found that the artificial representations in the lower-level layers of the trained AlexNet model were strongly correlated with the neural representation in V1, whereas the responses of model neurons in layers at the intermediate and higher-intermediate levels of the trained object classification model exhibited characteristics similar to those of neural activity in V4 neurons. These results suggest that the trained AlexNet model may gradually establish artificial representations for object classification through the hierarchy of its network, in a similar manner to the neural mechanisms by which afferent transmission beginning in the low-level features gradually establishes object recognition as signals progress through the hierarchy of the ventral visual pathway.

Abstract
Purpose
To investigate the choriocapillaris changes associated with pachychoroid pigment epitheliopathy (PPE) in comparison with healthy eyes.
Methods
Nine 3 × 3 mm macular optical coherence tomography angiography images were acquired in patients with PPE and age-matched healthy participants. Multiple en face image averaging of the choriocapillaris was binarized for quantitative image analysis of the flow voids. In PPE eyes, we evaluated the presence of pachyvessels and the association between the location of the choriocapillaris flow deficit and pachyvessels.
Results
Thirty-two eyes with PPE and 30 eyes of healthy participants were included. In PPE eyes, the mean total area (1.16 ± 0.18 vs. 0.91 ± 0.16, p < 0.001) and average size of the flow voids (790 ± 144 vs. 520 ± 138; p < 0.001) were significantly larger than those in control eyes. Composite images of the choriocapillaris and choroid showed choriocapillaris flow deficits just above and outside the pachyvessels. The mean proportion of the flow void area overlying the pachyvessels against the whole flow void area of the choriocapillaris was 21.3% ± 10.2% (9.38%-44.42%) in PPE eyes.
Conclusions
In PPE eyes, the blood flow area of the choriocapillaris decreased diffusely within the macular area compared to control eyes, and the choriocapillaris flow deficit was not necessarily related to pachyvessel location.

Abstract
Melatonin is a promising reagent that can improve assisted reproductive technology (ART) outcomes in infertility patients. However, melatonin is not effective for all infertile patients, and it remains unclear for which patients melatonin would be effective. This study examined the effects of melatonin on ART outcomes and examined its mechanisms. Melatonin increased the fertilization rate in patients whose fertilization rates in the previous cycle were less than 50%, but not in patients whose fertilization rates were more than 50% in the previous cycle. Melatonin increased the blastocyst formation rate in patients whose embryo development rates in the previous cycle were less than 50%, but not in patients whose embryo development rates were more than 50% in the previous cycle. To clarify its mechanisms, transcriptome changes by melatonin treatment in granulosa cells (GCs) of the patients were examined by RNA-sequence. Melatonin treatment altered the transcriptomes of GCs of patients with poor ART outcomes so that they were similar to the transcriptomes of patients with good ART outcomes. The altered genes were associated with the inhibition of cell death and T-cell activity, and the activation of steroidogenesis and angiogenesis. Melatonin treatment was effective for patients with poor fertilization rates and poor embryo development rates in the previous ART cycle. Melatonin alters the GCs transcriptome and, thus, their functions, and this could improve the oocyte quality, leading to good ART outcomes.

Abstract
PURPOSE To investigate whether the efficacy of anti-vascular endothelial growth factor (VEGF) monotherapy for polypoidal choroidal vasculopathy (PCV) differs between pachychoroid and non-pachychoroid phenotypes in the long term. METHODS This retrospective longitudinal study included 115 treatment-naïve eyes in 115 consecutive patients with symptomatic PCV who were treated with anti-VEGF monotherapy and were followed up for 5 years. Eligible eyes were assigned to either a pachy-PCV group, with a pachychoroid phenotype, or a non-pachy-PCV group, without a pachychoroid phenotype. Best-corrected visual acuity (BCVA) and other parameters over a 5-year period were compared between the groups. RESULTS Forty-eight eyes and 67 eyes were classified into the pachy-PCV and non-pachy-PCV groups respectively. Baseline and 5-year BCVA (logarithm of the minimum angle of resolution) were 0.19 ± 0.20 and 0.16 ± 0.28 in the pachy-PCV group, respectively, and 0.25 ± 0.26 and 0.26 ± 0.36 in the non-pachy-PCV group respectively. BCVA did not change significantly in either group (p = 0.18 and 0.08 respectively). BCVA did not differ between the groups at any observation time-point. Subfoveal choroidal thickness (SFCT) at baseline and at 5 years was significantly higher in the pachy-PCV group than in the non-pachy-PCV group (both p < 0.001); however, the mean rate of decrease in SFCT did not differ in either group over the 5-year period (22% vs. 23%, p = 0.81). CONCLUSION Our findings suggest that anti-VEGF monotherapy was similarly effective for pachychoroid- and non-pachychoroid-phenotype eyes with PCV, for at least 5 years, although further studies are required.

Abstract
Purpose To elucidate the incidence and treatment pattern of active exudative age-related macular degeneration (AMD). Design A population-based cohort study conducted using the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB), a national claims database managed by the Japanese Ministry of Health, Labour, and Welfare (MHLW). Participants The entire Japanese population aged 40 years or older (76 million people). Methods With the permission of the MHLW, we accessed the complete NDB dataset and identified patients with newly diagnosed active exudative AMD between 2011 and 2018. The incidence of active exudative AMD was categorized by age and sex per year between 2011 and 2018; moreover, details regarding first-line therapy and number of anti-vascular endothelial growth factor (VEGF) injections per elapsed year since initial treatment were obtained and changes in treatment pattern were investigated. Main Outcome Measures Incidence rate of active exudative AMD. Results During the specified 8-year period, 246 064 incident cases of active exudative AMD were identified; 61.4% of these patients were men. The overall incidence rate was 40.66 per 100 000 person-years (95% confidence interval [CI], 40.49–40.82) in the general population aged 40 years or older, 53.22 (95% CI, 52.95–53.49) in men, and 29.78 (95% CI, 29.60–29.98) in women. Mean age of onset was lower in men than in women (72.51 ± 10.50 years vs. 73.90 ± 10.46 years). Among patients with newly diagnosed active exudative AMD, 92.9% received anti-VEGF injections for initial treatments, whereas 1.8% underwent combination therapy with photodynamic therapy. The number of anti-VEGF injections in the first year (0–12 months), second year (13–24 months), and third year (25–36 months) after the initial injection was 3.66 ± 2.30, 1.39 ± 2.20, and 1.23 ± 2.19, respectively. Patients who received fewer injections in the first year received fewer injections in subsequent years and vice versa. Conclusions This is a relatively large population-based study on the detailed epidemiology and actual treatment patterns of active exudative AMD in clinical practice. Our results can be a fundamental information source to ensure healthy eyes and promote well-being for all at all ages.

Abstract
Extracellular polysaccharides produced by Lactobacillus have been shown to stimulate the immune system, suppress reactivity to allergens, and protect from infections; these properties underlie the use of Lactobacillus in probiotic formulations and in the prevention and treatment of urinary tract infections. However, Lactobacillus can be independently isolated at high numbers from sites of infection and has been rarely considered as the causative agent of infections in immunocompromised individuals. We herein report the case of a 46‐year‐old female patient who developed pyelonephritis due to Lactobacillus following total thyroidectomy for papillary thyroid cancer. The patient also had to fast due to postoperative vocal cord paralysis and received steroid treatment. As illustrated in the clinical course of our patient, Lactobacillus can be overlooked as a contaminant in culture samples and should be suspected as the etiology of infection especially in patients with weakened immune responses. We suggest that the detection of Lactobacillus in culture these patients might be an indication to initiate appropriate antibiotic treatment without delay.

Abstract
Distinguishing between late‐onset TINU syndrome and drug‐induced AIN remains difficult given that patients with TINU syndrome may develop uveitis long after the onset of AIN. Therefore, ophthalmic examination is required not only upon diagnosis but also continuously or when eye symptoms and relapse of urinary findings are observed.

Abstract
We previously reported that CCAAT/enhancer-binding protein beta (C/EBPβ) is the pioneer factor inducing transcription enhancer mark H3K27 acetylation (H3K27ac) in the promoter and enhancer regions of genes encoding insulin-like growth factor–binding protein-1 (IGFBP-1) and prolactin (PRL) and that this contributes to decidualization of human endometrial stromal cells (ESCs). Peroxisome proliferator–activated receptor gamma coactivator 1-alpha (PGC-1α; PPARGC1A) is a transcriptional coactivator known to regulate H3K27ac. However, although PGC-1α is expressed in ESCs, the potential role of PGC-1α in mediating decidualization is unclear. Here, we investigated the involvement of PGC-1α in the regulation of decidualization. We incubated ESCs with cAMP to induce decidualization and knocked down PPARGC1A to inhibit cAMP-induced expression of IGFBP-1 and PRL. We found cAMP increased the recruitment of PGC-1α and p300 to C/EBPβ-binding sites in the promoter and enhancer regions of IGFBP-1 and PRL, corresponding with increases in H3K27ac. Moreover, PGC-1α knockdown inhibited these increases, suggesting PGC-1α forms a histone-modifying complex with C/EBPβ and p300 at these regions. To further investigate the regulation of PGC-1α, we focused on C/EBPβ upstream of PGC-1α. We found cAMP increased C/EBPβ recruitment to the novel enhancer regions of PPARGC1A. Deletion of these enhancers decreased PGC-1α expression, indicating that C/EBPβ upregulates PGC-1α expression by binding to novel enhancer regions. In conclusion, PGC-1α is upregulated by C/EBPβ recruitment to novel enhancers and contributes to decidualization by forming a histone-modifying complex with C/EBPβ and p300, thereby inducing epigenomic changes in the promoters and enhancers of IGFBP-1 and PRL.

Abstract
PURPOSE To identify susceptibility genes for macular neovascularization (MNV) development in central serous chorioretinopathy (CSC). DESIGN Genome-wide survival analysis using a longitudinal cohort study. PARTICIPANTS We included 402 and 137 patients with CSC but without MNV at their first visit from the Kyoto CSC Cohort and Kobe CSC dataset, respectively. All patients underwent detailed ophthalmologic examinations, including multimodal imaging, such as fundus autofluorescence, spectral-domain optical coherence tomography, and fluorescein angiography/indocyanine green angiography and/or optimal coherence tomography angiography. METHODS We conducted a genome-wide survival analysis using the Kyoto CSC Cohort. We applied the Cox proportional hazard model to adjust for age, sex, and the first principal component. Single nucleotide polymorphisms (SNPs) with P-values <1.0×10-5 were carried forward to the replication in the Kobe CSC dataset. Moreover, we evaluated the contribution of previously-reported age-related macular degeneration (AMD) susceptibility loci. We used FUMA and ToppFun for the functional enrichment analysis. MAIN OUTCOME MEASURES The association between SNPs and MNV development in patients with CSC. RESULTS Rs370974631 near ARMS2 displayed a genome-wide significant association in the meta-analysis of discovery and replication result (hazard ratio [HR]meta = 3.63; Pmeta = 5.76×10-9). Among previously-reported AMD susceptibility loci, we additionally identified CFH rs800292 (HR = 0.39, P = 2.55×10-4), COL4A3 rs4276018 (HR = 0.26, P = 1.56×10-3), and B3GALTL rs9564692 (HR = 0.56, P = 8.30×10-3) as susceptibility loci for MNV development in CSC. The functional enrichment analysis revealed significant enrichment of eight pathways (GO:0051561, GO:0036444, GO:0008282, GO:1990246, GO:0015272, GO:0030955, GO:0031420, and GO:0005242) related to ion transport. CONCLUSIONS ARMS2, CFH, COL4A3, and B3GALTL were identified as susceptibility genes for MNV development in CSC. The aforementioned four genes are known as susceptibility genes for AMD, whereas COL4A3 and B3GALTL were previously reported to be polypoidal choroidal vasculopathy (PCV)-specific susceptibility genes. Our findings revealed the shared genetic susceptibility between PCV and MNV secondary to CSC.

Abstract
PURPOSE To investigate predictors of early displacement of submacular hemorrhage (SMH) by simple intravitreal SF6 gas injection. METHODS This retrospective study included 16 eyes of 16 consecutive patients (age: 74.5 ± 7.7 years; 15 men) with large SMH treated with simple intravitreal SF6 gas before inception of subretinal tissue plasminogen activator injection at our institution. The SMH displacement was graded at 1-week posttreatment as 0, 1, or 2. Central retinal thickness, central choroidal thickness, SMH height, SMH area, disease duration, use of anticoagulant or antiplatelet drugs, and contrast-to-noise ratio (CNR) of SMH on optical coherence tomography images were recorded. Correlations between displacement grading and baseline parameter were analyzed. RESULTS Univariable correlation analysis revealed association of the 1-week displacement grading with the CNR (P = 0.004; r = -0.68) and SMH height (P = 0.03; r = -0.55). The CNR was most strongly associated with 1-week displacement on multivariable correlation analysis (P = 0.01; β = -0.60). CONCLUSION Findings of the present study showed that the CNR of SMH was a useful predictor of early displacement of large SMH after simple intravitreal SF6 gas injection. When vitrectomy with subretinal injection of tissue plasminogen activator is difficult in patients with large SMH, with low CNR on optical coherence tomography, simple intravitreal SF6 gas injection may be a treatment option.

Abstract
The differential cross sections of the Σ^{-}p→Λn reaction were measured accurately for the Σ^{-} momentum (p_{Σ}) ranging from 470 to 650 MeV/c at the J-PARC Hadron Experimental Facility. Precise angular information about the Σ^{-}p→Λn reaction was obtained for the first time by detecting approximately 100 reaction events at each angular step of Δcosθ=0.1. The obtained differential cross sections show a slightly forward-peaking structure in the measured momentum regions. The cross sections integrated for -0.7≤cosθ≤1.0 were obtained as 22.5±0.68 [statistical error(stat.)] ±0.65 [systematic error(syst.)] mb and 15.8±0.83(stat)±0.52(syst) mb for 470<p_{Σ}(MeV/c)<550 and 550<p_{Σ}(MeV/c)<650, respectively. These results show a drastic improvement compared with past measurements of the hyperon-proton scattering experiments. They will play essential roles in updating the theoretical models of the baryon-baryon interactions.

Abstract
BACKGROUND To evaluate the 3-year outcome in eyes with neovascular age-related macular degeneration (nAMD) treated with intravitreal anti-vascular endothelial growth factor monotherapy or rescue therapy using standard verteporfin photodynamic therapy (PDT), and corroborate efficacy of rescue PDT. METHODS Patients were administered aflibercept injections once a month for 3 months followed by once every 2 months in the first year. After year 1, treatment with aflibercept monotherapy as indicated or in combination with PDT at the retinal specialist's discretion. Only cases completing the three-year follow-up were included. Regression analysis with visual acuity and macular atrophy at year 3 was performed for the dependent variable. RESULTS Of the 292 eyes, 15 eyes underwent rescue PDT following year 1. The best-corrected visual acuity (logarithm of minimal angle of resolution, mean/Snellen equivalent ± SD) was 0.35 (20/45) ± 0.38, 0.23 (20/30) ± 0.36, 0.26 (20/35) ± 0.38, and 0.31 (20/40) ± 0.42 at baseline, year 1, year 2, and year 3, respectively. Multiple regression analysis revealed that the rescue PDT was significantly associated with macular atrophy and poor visual outcome at year 3 (odds ratio = 1.2, p < 0.001; β = 0.23, p = 0.0029, respectively). CONCLUSIONS The visual outcome in eyes with nAMD retained baseline levels at year 3; however, patients treated with rescue PDT developed macular atrophy more frequently and poor visual outcomes.

Abstract
Purpose To evaluate the dosimetric advantages of daily adaptive radiotherapy (DART) in intensity‐modulated proton therapy (IMPT) for high‐risk prostate cancer by comparing estimated doses of the conventional non‐adaptive radiotherapy (NART) that irradiates according to an original treatment plan through the entire treatment and the DART that uses an adaptive treatment plan generated by using daily CT images acquired before each treatment. Methods Twenty‐three patients with prostate cancer were included. A treatment plan with 63 Gy (relative biological effectiveness (RBE)) in 21 fractions was generated using treatment planning computed tomography (CT) images assuming that all patients had high‐risk prostate cancer for which the clinical target volume (CTV) needs to include prostate and the seminal vesicle (SV) in our treatment protocol. Twenty‐one adaptive treatment plans for each patient (total 483 data sets) were generated using daily CT images, and dose distributions were calculated. Using a 3 mm set‐up uncertainty in the robust optimization, the doses to the CTV, prostate, SV, rectum, and bladder were compared. Results Estimated accumulated doses of NART and DART in the 23 patients were 60.81 ± 3.47 Gy (RBE) and 63.24 ± 1.04 Gy (RBE) for CTV D99 (p < 0.01), 62.99 ± 1.28 Gy (RBE) and 63.43 ± 1.33 Gy (RBE) for the prostate D99 (p = 0.2529), and 59.07 ± 5.19 Gy (RBE) and 63.17 ± 1.04 Gy (RBE) for SV D99 (p < 0.001). No significant differences were observed between NART and DART in the estimated accumulated dose for the rectum and bladder. Conclusion Compared with the NART, DART was shown to be a useful approach that can maintain the dose coverage to the target without increasing the dose to the organs at risk (OAR) using the 3 mm set‐up uncertainty in the robust optimization in patients with high‐risk prostate cancer.
