Effect of magnification error and axial length on circumpapillary capillary density and retinal nerve fiber layer thickness.

This study aimed to evaluate the effect of magnification error and axial length (AL) on circumpapillary capillary density (cpCD) and circumpapillary retinal nerve fiber layer thickness (cpRNFLT) in healthy eyes. Seventy-two healthy eyes of 72 subjects with AL 24.7 ± 1.5 mm (range: 20.9-28.0 mm) were enrolled in this retrospective cross-sectional study and underwent optical coherence tomography angiography scanning. Magnification corrected measurement areas were obtained using AL upon which corrected cpCD, cpRNFLT values were determined. Relationships between AL and the percentage difference between corrected and uncorrected values (ΔcpCD, ΔcpRNFLT) as well as the effect of AL on magnification corrected cpCD, cpRNFLT were evaluated. ΔcpCD significantly increased with AL in the global, inferior nasal and superior nasal sectors (all p < 0.001). ΔcpRNFLT significantly increased with AL in global and all sectors (all p < 0.001) and the correlations were significantly stronger than that of ΔcpCD-AL in all sectors (all p < 0.001). Corrected cpCD did not associate with AL while corrected cpRNFLT demonstrated a significant positive association with AL in the global (p = 0.005) and temporal sector (p < 0.001). Magnification error led to a significant underestimation of cpCD in eyes with longer AL although its underestimation and the effect of AL was smaller in comparison to that of cpRNFLT.

Effects of Deep Optic Nerve Head Structures on Bruch's Membrane Opening- Minimum Rim Width and Peripapillary Retinal Nerve Fiber Layer.

PURPOSE: To explore the effects of deep optic nerve head (ONH) structures on Bruch's membrane opening (BMO)-minimum rim width (MRW) and peripapillary retinal nerve fiber layer thickness (pRNFLT) in healthy eyes. DESIGN: Prospective cross-sectional study. METHODS: Two hundred five healthy eyes of 141 subjects (mean ± standard deviation of age and axial length (AXL): 46.9 ± 10.0 years and 24.79 ± 1.15 mm) were enrolled. Best fit multivariable linear mixed models identified factors associated with BMO-MRW and pRNFLT. Explanatory variables included age, gender, AXL, BMO and anterior scleral canal opening (ASCO) area and ovality, magnitude of BMO and ASCO shift, peripapillary choroidal thickness, lamina cribrosa (LC) parameters, prelaminar thickness, and peripapillary scleral (PPS) angle. RESULTS: Thinner BMO-MRW was associated with older age, smaller ASCO/BMO offset magnitude, larger BMO area, thinner prelaminar thickness, deeper LC, and thinner pRNFLT (P = .011, <.001, .004, <.001, <.001, <.001 respectively). Thinner pRNFLT was associated with shorter AXL, smaller ASCO area, a more posteriorly bowed PPS, shallower LC and thinner BMO-MRW. (P = .030, .002, .035, .012, <.001 respectively) CONCLUSIONS: BMO-MRW and pRNFLT were influenced by several deep ONH structures such as BMO and ASCO position shift, BMO or ASCO area, prelaminar thickness, PPS bowing and LC depth in addition to patient characteristics such as age and AXL. The degree and/or direction of associations varied between deep ONH structures and BMO-MRW or pRNFLT. Despite both BMO-MRW and pRNFLT being surrogate parameters for RGC loss, a complex relationship with ONH deep-layer morphology was indicated.

Association of Bergmeister Papilla and Deep Optic Nerve Head Structures With Prelaminar Schisis of Normal and Glaucomatous Eyes.

PURPOSE: To investigate factors associated with the severity of prelaminar schisis (PLS) in heathy subjects and glaucoma patients. DESIGN: Prospective cross-sectional study. METHODS: A total of 217 eyes of 217 subjects (110 normal eyes and 107 open angle glaucoma eyes) were studied. Frequency and severity of PLS were compared between normal and glaucomatous eyes. Multivariate logistic models were used to assess factors associated with the severity of PLS. Factors considered were age, axial length, glaucomatous damage indices, Bruch membrane opening (BMO) and anterior scleral canal opening parameters, tractional forces (posterior vitreous staging and presence of Bergmeister papilla), circumpapillary choroidal thickness, lamina cribrosa (LC) parameters, and peripapillary scleral (PPS) angle. RESULTS: The frequency of PLS was 70.9% in normal eyes and 72.0% in glaucomatous eyes. There was no difference in frequency and severity between the groups. The presence of Bergmeister papilla was the strongest predictor of a more severe PLS in both normal and glaucomatous eyes (odds ratio [OR] + 9.78, 12.5; both P < .001). A larger PPS angle in normal eyes (OR = 1.19; P = .003) and a larger BMO area and a deeper LC depth in glaucomatous eyes (OR = 1.08, 1.05; both P = .038) were associated with severity of PLS. CONCLUSIONS: The severity of PLS was strongly associated with the presence of Bergmeister papilla, suggesting a traction-related phenomenon. Correlation of PLS severity with larger BMO area and deeper LC depth, which are optic nerve head structures associated with glaucoma, suggested its possible relationship with glaucomatous damage.

Ketogenic effects of medium chain triglycerides containing formula and its correlation to breath acetone in healthy volunteers: a randomized, double-blinded, placebo-controlled, single dose-response study.

The efficacy of low-carbohydrate, high-fat diets, such as ketogenic diets, for cancer patients is of research interest. We previously demonstrated the efficacy of the ketogenic diet in a case study in which medium-chain triglycerides (MCTs) or MCT-containing formula (ketogenic formula) was used as a supplement to increase blood ketone bodies. However, little is known about the amounts needed to induce ketogenic effects and about the usefulness of monitoring of breath acetone. To investigate the pharmacokinetics of MCTs and their metabolites, blood ketone bodies and breath acetone, 24 healthy subjects received one of four single oral doses of the ketogenic formula (equivalent to 0, 10, 20, and 30 g of MCTs) under fasting conditions. Total blood ketone bodies, ß-hydroxybutyrate, octanoic acid, and decanoic acid were increased in a dose-dependent manner. The ketogenic effect was considered to depend on octanoic and decanoic acids, because a positive correlation was observed between them. A strong positive correlation was also observed between total serum ketone bodies and breath acetone at each time points. Therefore, monitoring breath acetone levels seems a less invasive method to predict blood concentrations of ketone bodies during ketogenic diet therapy.

Long-Term Effects of a Ketogenic Diet for Cancer.

A ketogenic diet has been proposed as a potential supportive therapy for cancer patients, although its long-term influence on survival rates remain controversial. In our previous report, we presented promising results for 37 of 55 patients with advanced cancer enrolled between 2013 and 2018 who remained on a ketogenic diet for at least 3 months. We followed all 55 patients until March 2023 and analyzed the data up to March 2022. For the 37 patients with previously reported promising results, the median follow-up period was 25 (range of 3-104) months and 28 patients died. The median overall survival (OS) in this subset of 37 patients was 25.1 months and the 5-year survival rate was 23.9%. We also evaluated the association between the duration of the ketogenic diet and outcome in all 55 patients, except for 2 patients with insufficient data. The patients were divided into two groups: those who followed the diet for ≥12 months (n = 21) and those who followed it for <12 months (n = 32). The median duration of the ketogenic diet was 37 (range of 12-99) months for the ≥12 months group and 3 (range of 0-11) months for the <12 months group. During the follow-up period, 41 patients died (10/21 in the ≥12 months group and 31/32 in the <12 months group). The median OS was 19.9 months (55.1 months in the ≥12 months group and 12 months in the <12 months group). Following the inverse probability of treatment weighting to align the background factors of the two groups and make them comparable, the adjusted log-rank test showed a significantly better OS rate in the group that continued the ketogenic diet for a longer period (p < 0.001, adjusted log-rank test). These results indicate that a longer continuation of the ketogenic diet improved the prognosis of advanced cancer patients.

Structure Function Relationships of Vessel Density and Retinal Nerve Fiber Layer Thickness in Early Glaucomatous Eyes With High Myopia.

Purpose: The purpose of this study was to evaluate the structure function relationship of circumpapillary vessel density (cpVD) with visual field sensitivity (VFS) and compare its characteristics with circumpapillary retinal nerve fiber layer thickness (cpRNFLT) in early glaucomatous (EG) and normal eyes with and without high myopia (HM). Methods: Seventy-five EG (mean deviation > -6 dB) and 7 normal eyes with HM (axial length [AL] >26.5 mm) and 111 EG and 11 normal eyes without HM were enrolled in this retrospective cross-sectional study. All patients underwent circumpapillary optical coherence tomography (OCT) and OCT angiography (OCTA) scanning with the Cirrus HD-6000 with AngioPlex OCTA (Carl Zeiss Meditec, Dublin, CA, USA). Structure function correlations were determined by comparing global, superior, inferior, and Garway-Heath sectoral values for cpVD and cpRNFLT with its corresponding 24-2 and 10-2 VFS of Humphrey Visual Field (HFA) analyzer. Results: CpVD showed no significant correlations with AL except for the nasal sector (P = 0.044), whereas cpRNFLT demonstrated significant positive association with AL in the global (P = 0.024), nasal (P = 0.020), and temporal (P < 0.001) sectors. In HM eyes, global and sectoral cpVD significantly correlated with corresponding VFS in all 24-2/10-2 VF sectors (all P < 0.05). CpVD-VFS correlation was significantly stronger than cpRNFLT-VFS in the nasal sector of HM eyes (P = 0.002) and temporal and inferior temporal sector of eyes without HM (P = 0.008 and P = 0.042, respectively). Conclusions: In EG eyes with HM, cpVD was less affected by AL in comparison to cpRNFLT and cpVD-VFS correlation was significant in all 24-2/10-2 VF sectors. AL-associated advantages of cpVD-VFS over cpRNFLT-VFS were observed.

Deep Optic Nerve Head Structures Associated With Increasing Axial Length in Healthy Myopic Eyes of Moderate Axial Length.

PURPOSE: To elucidate which swept-source optical coherence tomography (OCT)-derived optic nerve head (ONH) parameters are associated with longer axial length (AXL) in healthy myopic eyes. DESIGN: Prospective cross-sectional observational study. METHODS: Two hundred eleven healthy eyes of 140 participants (96 emmetropic-mild myopic [AXL: 22.2-24.5 mm], 83 moderately myopic [24.5-26.0 mm], and 32 highly myopic [26.0-27.4 mm] eyes) were enrolled. Bruch membrane opening (BMO), anterior scleral canal opening (ASCO) area and ovality, minimum rim width, parameters defining misalignment between the BMO and ASCO planes, OCT-defined region of perineural canal retinal epithelium atrophy and externally oblique choroidal border tissue, circumpapillary retinal nerve fiber layer thickness (cpRNFLT), circumpapillary choroidal thickness (cpChT), lamina cribrosa parameters, and peripapillary scleral (PPS) angle were calculated from BMO-centered radial scans reconstructed from 3D raster scans. Multivariate linear mixed models were used to elucidate ONH parameters that are independently associated with AXL. RESULTS: Longer AXL was associated with a greater misalignment between ASCO and BMO planes, larger region of externally oblique choroidal border tissue, thinner cpChT, larger PPS angle, larger ASCO area, and thicker cpRNFLT (all P < .040 after Bonferroni's correction for number of included explanatory variables). CONCLUSIONS: A greater misalignment between BMO and ASCO planes, thinner choroid, a more posteriorly bowed PPS, an enlargement of ASCO, and thicker cpRNFLT were each associated with longer AXL. An enhanced understanding of these AXL-associated configurations should provide essential information to improve our ability to detect glaucoma-induced ONH morphology in myopic eyes.

Prostaglandin-Associated Periorbitopathy Symptom Alleviation After Switching Prostaglandin F Receptor Agonist to EP2 Receptor Agonist in Patients with Glaucoma.

Purpose: Prostaglandin-associated periorbitopathy in patients with glaucoma is reportedly not caused by EP2 agonist, but it has been a cosmetic problem with prostaglandin F receptor (FP) agonists. In this study, patients with prostaglandin-associated periorbitopathy on FP agonists were switched to EP2 agonist and changes were investigated. Methods: Patients complaining of prostaglandin-associated periorbitopathy were included. The FP agonist was switched to EP2 agonist (omidenepag isopropyl), and patients were followed up for 7 months. Frontal photographs were taken at every visit, and objective changes in deepening of the upper eyelid sulcus were assessed by three observers. Subjective questionnaires (self-awareness of deepening of the upper eyelid sulcus, eyelid/peri-eyelid skin pigmentation, eyelash elongation, and conjunctival hyperemia) were acquired at the start and the endpoint. Factors associated with the change of prostaglandin-associated periorbitopathy were investigated using logistic regression analysis. Results: Included were 23 eyes of 23 patients (17 women; 60.6 years). At 7 months, objective deepening of the upper eyelid sulcus improved by 76%. The subjective questionnaires showed that deepening of the upper eyelid sulcus improved in 95%, eyelid/peri-eyelid skin pigmentation in 76%. The less extent of myopia was a significant factor in the eyes with improved eyelid/peri-eyelid skin pigmentation. After switching, no change in intraocular pressure or visual acuity was observed (P ≥ 0.22). Conclusion: Switching to omidenepag isopropyl increased patient satisfaction and might be the first step to lightening deepening of the upper eyelid sulcus and eyelid/peri-eyelid skin pigmentation. It was suggested that pigmentation may be more easily improved in nonmyopic eyes.

A multidimensional physical scale is a useful screening test for mild depression associated with childcare in Japanese child-rearing women.

Introduction: Maternal depression is one of the important problems of postpartum women. For its early detection and appropriate treatment, it is necessary to identify women at high risk for depression quickly and easily. Materials and methods: A simple screening scale for depression from physical aspects, the multidimensional physical scale (MDPS), which is a 17-item, self-report, three-step scale (0, 1, 2) according to the theory of Kampo medicine, was developed. The aim of the present study was to develop (n = 785) and validate (n = 350) the MDPS that was designed to rate the risk of depression. The Beck Depression Inventory-Second Edition was used for determination of depression. In the development cohort, the final model was determined using multi-regression logistic analysis. Results: The components of the MDPS for mothers (MDPS-M) were developed, containing the total score of MDPS (0-34 points) and resumption of menstruation or not (-3, 0 points). Receiver-operating characteristic curve analysis of the MDPS-M (-3 to 34) for identifying a high risk of depression showed moderately good discrimination [area under the curve (AUC) = 0.74, 95% confidence interval (CI): 0.70-0.78]. At the cutoff value of MDPS-M (9/10), its sensitivity, specificity, positive predictive value, and negative predictive value were 84.9, 45.7, 36.7, and 89.2%, respectively. External validation of the MDPS-M showed moderately good discrimination (AUC = 0.74, 95% CI: 0.68-0.79) using the same analysis as the development cohort. Conclusion: These results indicate that the MDPS-M is a useful, simple, clinical scale for early identification of mothers at high risk of depression in primary care.

Short-term outcomes of micropulse transscleral laser therapy using the revised delivery probe in refractory glaucoma.

PURPOSE: To evaluate the effectiveness of MicroPulse® transscleral laser therapy (MP-TLT) using both the original and revised MicroPulse P3® delivery probes in patients with refractory glaucoma. STUDY DESIGN: Retrospective study METHODS: We analyzed the data of patients with refractory glaucoma who underwent MP-TLT with the original and with the revised MicroPulse P3® Delivery Device from January 2018 to December 2020 at the University of Tokyo Hospital and who were followed up for 3 months. Patients' demographics, preoperative and postoperative intraocular pressure (IOP), medication scores, best-corrected visual acuity (BCVA), and complications were analyzed. RESULTS: This study enrolled 40 patients in both probe groups. At baseline, the mean IOP was 31.1 mmHg in the original group and 29.2 mmHg in the revised group, and it decreased to 22.6 mmHg and 21.6 mmHg after 3 months, respectively (paired t-test p=0.001, 0.001). No significant difference was noted between the number of medications and BCVA at baseline and 3 months in either probe group (paired t-test, p>0.05). Nor were any serious complications observed. CONCLUSION: MP-TLT using the revised MicroPulse P3® Delivery Device for the treatment of refractory glaucoma was effective in reducing IOP across glaucoma types with an excellent safety profile and was well-tolerated by the patients.

The Japan Frailty Scale is a promising screening test for frailty and pre-frailty in Japanese elderly people.

Frailty is one of the most important problems in a super-aged society. It is necessary to identify frailty quickly and easily at the bedside. We developed a simple patient-reported frailty screening scale, the Japan Frailty Scale (JFS), based on the aging concept of Kampo medicine. Eight candidate questions were prepared by Kampo medicine experts, and a simple prediction model was created in the development cohort (n = 434) and externally validated in an independent validation cohort (n = 276). The physical indicators and questionnaires associated with frailty were also comprehensively evaluated. The reference standard for frailty or pre-frailty was determined based on the Kihon checklist. In the development cohort, four questions, nocturia (0-2), lumbago (0-2), cold sensitivity (0-2), exhaustion (0-4), and age (0-1) were selected by multivariable logistic regression analysis. The total JFS score is 0-11. Receiver-operating characteristic curve analysis of the JFS for identifying frailty status showed moderately good discrimination (area under the curve (AUC) = 0.78, 95 % confidence interval (CI): 0.73-0.82). At the JFS cutoff value of 3/4 for frailty or pre-frailty, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were 86.9 %, 53.3 %, 62.8 %, and 81.7 %, respectively. External validation of the JFS showed moderately good discrimination (AUC = 0.76, 95 % CI: 0.70-0.81). The sensitivity, specificity, PPV, and NPV were 79.9 %, 61.4 %, 69.3 %, and 73.7 %, respectively. These results indicate that the JFS is a promising patient-reported clinical scale for early identification of pre-frail/frail patients at the bedside in primary care.

Clinical Importance of Body Composition in Improving Bone Mineral Density of Femoral Neck After Denosumab Therapy in Patients With Rheumatoid Arthritis or Collagen Diseases.

BACKGROUND/AIM: To investigate factors associated with increased bone mineral density (BMD) of the neck of femur in rheumatoid arthritis or collagen diseases receiving denosumab, focusing on body composition calculated by bioelectrical impedance analysis (n=90, 78 females). PATIENTS AND METHODS: We defined Δfemur as BMD (12 months minus baseline), using dual-energy X-ray absorptiometry after denosumab therapy. Factors associated with Δfemur were retrospectively investigated. RESULTS: Low skeletal muscle index (SMI) was observed in 6 males and 32 females. There was a significant difference in phase angle (PhA) of the left leg (LL) between the Δfemur ≥0 (n=70) and Δfemur <0 (n=20) groups (p=0.040) but not in SMI (p=0.310). Multiple regression analysis indicated that PhA of LL was significantly related to Δfemur (p=0.0398). CONCLUSION: PhA appears to be a clinically significant indicator of improvement of Δfemur in patients receiving denosumab.

Diagnostic ability and sectoral structure-function relationship of circumpapillary and macular superficial vessel density in early glaucomatous eyes.

This study aimed to evaluate the diagnostic ability and sectoral structure function relationship of circumpapillary vessel density (cpVD) and macular vessel density (mVD) with optical coherence tomography angiography (OCTA) in early glaucomatous (EG) eyes. 224 EG eyes of 167 patients (mean deviation (MD) > - 6 dB) and 70 normal eyes of 70 subjects were enrolled in this retrospective cross-sectional study. All patients underwent OCT and OCTA scanning. Diagnostic abilities were evaluated with area under receiver operating characteristic curves (AUROC). Structure function relationships of superior, inferior and Garway-Heath sectoral values with its corresponding visual field (VF) sensitivity were determined using linear mixed models. AUROCs were 0.798, 0.621, 0.876 and 0.835 for cpVD, mVD, circumpapillary retinal nerve fiber layer thickness (cpRNFLT) and ganglion cell-inner plexiform layer, respectively. AUROC of cpVD was significantly lower than cpRNFLT (P = 0.010) and higher than mVD (P < 0.001). All Garway-Heath sectors of cpVD significantly correlated with its corresponding VF sensitivity except for the nasal sector. MVD also showed significant structure function relationship and the correlations were stronger in the perifoveal region (6 mm annulus) than in the parafoveal region (3 mm annulus). CpVD demonstrated moderate diagnostic ability and both cpVD and mVD demonstrated significant association with VF sensitivity in EG eyes.

Ketogenic Effects of Multiple Doses of a Medium Chain Triglycerides Enriched Ketogenic Formula in Healthy Men under the Ketogenic Diet: A Randomized, Double-Blinded, Placebo-Controlled Study.

Ketogenic diets, which are carbohydrate-restricted high-fat diets, may have therapeutic effects on various diseases, including cancer. However, ketogenic diets are often not standardized and, therefore, results are difficult to interpret. We previously investigated the usefulness of ketogenic diets in cancer therapy, where ketogenic formulas (KF) were used as supplements to enhance blood ketone bodies; however, the amount of KF was determined empirically with reference to blood ketone bodies levels. Here, to determine a standardized optimal amount of KF, we investigated temporal changes in blood ketone bodies (acetoacetic acid (AcAc), ß-hydroxybutyrate (BHB)) and safety in 20 healthy individuals when KF was taken repeatedly under the conditions of a ketogenic diet (UMIN000034216). The diurnal variation in total ketone bodies, and AcAc and BHB levels significantly increased after lunch and after dinner, on the 4th day of KF administration. There were no significant safety issues related to KF in the context of anthropometric, metabolic, nutritional, urological and gastrointestinal parameters. In addition, ketogenic diets lead to changes in gut microbiota. KF showed a decrease in phylum Firmicutes. Our study provides baseline data of the usefulness of KF in a ketogenic diet.

Recovery of deepening of the upper eyelid sulcus after switching from prostaglandin FP receptor agonists to EP2 receptor agonist: a 3-month prospective analysis.

PURPOSE: To examine the effect of switching from a prostanoid FP receptor agonists to EP2 receptor agonist (omidenepag isopropyl) on the deepening of the upper eyelid sulcus (DUES) and intraocular pressure (IOP) in Japanese glaucoma patients over 3 months post treatment. STUDY DESIGN: Prospective observational study. METHODS: Patients with glaucoma who received FP receptor agonists treatment and had complained of DUES-related reduction in quality of life were included. Their FP receptor agonists was switched to omidenepag isopropyl without a drug holiday. At baseline and 1 and 3 months post-switch, photographs were taken and the changes in DUES were assessed by three independent observers. IOP and adverse events were also assessed. RESULTS: The study included 23 eyes of 23 patients (6 men, 17 women; average age, 60.6 years). After switching, DUES improved in 12 eyes at 1 month and in 16 eyes at 3 months; eyes in the remaining patients showed no worsening of the condition. The mean IOP before switching was 15.3 ± 3.3 mmHg (95% confidence interval 13.9-16.7 mmHg). Following the switch, the mean IOP values were 15.6 ± 3.3 mmHg (14.1-17.0 mmHg) at 1 month and 15.5 ± 3.3 mmHg (14.1-16.9 mmHg) at 3 months (P = 1.0 at 1 month, P = 1.0 at 3 months; both adjusted by Bonferroni correction). No adverse effects were observed. CONCLUSION: Omidenepag isopropyl improved DUES while maintaining IOP in over 70% of Japanese patients with glaucoma who exhibited DUES caused by FP receptor agonists; the improvement was observed within 3 months after switching from FP receptor agonists.

The Additive Effect of ROCK Inhibitor on Prostaglandin-Treated Japanese Patients with Glaucoma Indicating 15 mmHg and Under: ROCK U-15.

INTRODUCTION: We aimed to evaluate the additional effects and safety of a Rho-associated protein kinase (ROCK) inhibitor, ripasudil hydrochloride hydrate, in Japanese patients with primary open-angle glaucoma (POAG) with an intraocular pressure (IOP) of at most 15 mmHg undergoing prostaglandin F2α (FP) receptor agonist monotherapy (FP monotherapy). METHODS: In this prospective observational study, 30 Japanese patients with POAG and IOP of at most 15 mmHg (mean age 59.4 years; 10 men) who were undergoing FP monotherapy in both eyes were administered an additional dose of ripasudil hydrochloride hydrate (GLANATEC ophthalmic solution 0.4%: ripasudil) in one eye. The following factors were investigated at 1 and 3 months after the initiation of ripasudil treatment: (1) magnitude of change in IOP between the treated and contralateral untreated eyes, (2) number of treated eyes showing 20% and 30% IOP reduction, (3) IOP difference between treated and contralateral untreated eyes, and (4) safety during the treatment period. Both (1) and (3) were analyzed using the mixed-effect model for repeated measurements. RESULTS: The treated eyes showed significant reduction in IOP at 1 month (- 1.92 mmHg, P < 0.001) and 3 months (- 1.81 mmHg, P < 0.001). In contrast, contralateral untreated eyes did not show IOP reduction at 1 month (0.53 mmHg, P = 0.016) and 3 months (0.38 mmHg, P = 0.15). IOP reduction of - 20% and - 30% was achieved in 9 (30%) and 3 (10%) treated eyes, respectively. There were significant differences in IOP between the treated and contralateral untreated eyes at 1 month (- 2.46 mmHg, P < 0.001) and 3 months (- 2.20 mmHg, P < 0.001). Two patients experienced local adverse events (facial edema, one patient at week 1; blepharitis, one patient at 1 month); they recovered quickly after stopping ripasudil administration. CONCLUSION: In patients with POAG with an IOP of at most 15 mmHg undergoing FP monotherapy, the addition of ripasudil resulted in significant IOP lowering at 1 and 3 months. Ripasudil could be used to enhance the outcome of FP monotherapy. TRIAL REGISTRATION: Registered UMIN ID: UMIN000030742.

Frequency of hypotonic maculopathy observed by spectral domain optical coherence tomography in post glaucoma filtration surgery eyes.

PURPOSE: To report the frequency of post glaucoma filtration surgery hypotonic maculopathy determined by spectral domain optical coherence tomography (SD-OCT). METHODS: A cross-sectional retrospective observational study. Post glaucoma filtration surgery patients whose intraocular pressures (IOP) achieved 30% reduction from baseline or was controlled to IOP <14 mm Hg and had SD-OCT images and fundus photographs were enrolled. Hypotonic maculopathy was diagnosed independently on SD-OCT images and on fundus photographs. RESULTS: 112 eyes of 88 patients were included in this study. 17 eyes of 14 patients were diagnosed with hypotonic maculopathy on SD-OCT images (17/112, 15.2%). Among these eyes, only 3 eyes were also diagnosed with hypotony maculopathy on fundus photography. Hypotonic maculopathy on SD-OCT was found only in eyes with IOP ≤10 mm Hg. (17.4% in eyes with IOPs between 7 and 10 mm Hg, and 22.7% in eyes with IOP ≤ 6 mm Hg). Associations with age, sex, central corneal thickness, refractive error, IOP reduction rate and interval between surgery and OCT acquisition were not significant (P > 0.05). CONCLUSION: In most cases, hypotonic maculopathy detected by SD-OCT were not recognizable on fundus photographs. Hypotonic maculopathy was detected not only in eyes with conventional ocular hypotony (IOP < 6 mm Hg) but also in eyes with IOP between 7 and 10 mm Hg.

Promising Effect of a New Ketogenic Diet Regimen in Patients with Advanced Cancer.

A ketogenic diet is expected to be an effective support therapy for patients with cancer, but the degree and duration of carbohydrate restriction are unclear. We performed a case series study of a new ketogenic diet regimen in patients with different types of stage IV cancer. Carbohydrates were restricted to 10 g/day during week one, 20 g/day from week two for three months, and 30 g/day thereafter. A total of 55 patients participated in the study, and data from 37 patients administered the ketogenic diet for three months were analyzed. No severe adverse events associated with the diet were observed. Total ketone bodies increased significantly, and both fasting blood sugar and insulin levels were suppressed significantly for three months after completion of the study. Five patients showed a partial response on Positron emission tomography-computed tomography (PET-CT) at three months. Three and seven patients showed complete and partial responses, respectively at one year. Median survival was 32.2 (maximum: 80.1) months, and the three-year survival rate was 44.5%. After three months on the ketogenic diet, the serum Alb, BS, and CRP (ABC) score could be used to stratify the patients into groups with significantly different survival rates (p < 0.001, log-rank test). Our ketogenic diet regimen is considered to be a promising support therapy for patients with different types of advanced cancer.

The effects of a nutritional supplement containing salacinol in neonatal Thoroughbred foals.

A nutritional supplement containing salacinol (NSS) was administered to Thoroughbred foals daily beginning 21 days after birth, and clinical signs and intestinal microbiota were analyzed. The average number of days for which foals exhibited a fever between 21 and 110 days after birth was determined. The number of days was significantly reduced, by approximately 1/3, in the NSS group compared with the control group. Furthermore, improved weight gain was observed in the NSS group compared with the control group. By analyzing the intestinal microbiota, it was determined that the ratio of Clostridium cluster XIVa increased after 3 weeks of NSS administration. These results demonstrate that the daily administration of NSS might improve the intestinal environment of neonatal foals and be useful for health.

Comparison of retinal ganglion cell-related layer asymmetry between early glaucoma eyes with superior and inferior hemiretina damage.

AIM: To compare retinal ganglion cell (RGC)-related layer thickness asymmetry between early open-angle glaucoma (EG) eyes with superior and inferior hemiretina damage. METHODS: This was a retrospective study including 95 EG eyes (mean deviation >-2 dB, including 43 preperimetric glaucoma eyes) with photographically determined glaucomatous retinal nerve fibre layer defect and disc change confined to one hemiretina, and 93 age, sex and refraction matched normal subjects as controls. Ganglion cell complex, ganglion cell layer+inner plexiform layer and circumpapillary retinal nerve fibre layer thickness measured by spectral domain optical coherence imaging were compared between the affected and unaffected hemiretinae within each glaucoma eye as well as to those of the corresponding hemiretina of normal control eyes. RESULTS: Intraeye comparison revealed that there was no significant difference in all parameters between the affected and unaffected hemiretinae in eyes with superior hemiretina damage (p=0.110~0.343) while all parameters were thinner in the affected inferior hemiretina compared with the unaffected superior hemiretina in eyes with inferior hemiretina damage (p<0.001). The affected hemiretina of both groups were thinner compared with normal controls (p<0.001). All parameters of the unaffected hemiretina of eyes with superior hemiretina damage were thinner than normal controls (p<0.001), while eyes with inferior hemiretina damage showed no significant difference compared with those of their corresponding hemiretina of normal eyes (p=0.086~0.924). CONCLUSION: The pattern of RGC damage in early stage glaucoma may differ depending on which horizontal hemiretina is affected first.
