Discriminant prediction equation using an optical biometer for identifying post-myopic laser vision correction eyes.

PURPOSE: To create an equation for identifying post-myopic laser vision correction (M-LVC) eyes by using corneal shape parameters in swept-source optical coherence tomography (SS-OCT) biometer and verify its accuracy. SETTING: Nagoya eye clinic, Nagoya, Japan. DESIGN: Retrospective evaluation of a screening approach. METHODS: The control participants were selected retrospectively from patients who visited our clinic for cataract surgery or refractive surgery. M-LVC patients were selected retrospectively from patients who visited our clinic for cataract surgery or M-LVC postoperative checkups. The control and post-M-LVC patients with keratometric values between 39 diopters (D) and 43 D were included in the final analysis. Patients were randomly assigned to equation-creation and validation groups in a 2:1 ratio. To discriminate post-M-LVC patients from control participants, multiple logistic regression analysis was performed with the corneal shape parameters from the optical biometer as independent variables. RESULTS: The M-LVC and control groups consisted of 90 eyes from 90 patients and 97 eyes from 97 patients, respectively. The average keratometry (Ave-K) values did not differ significantly between the control and M-LVC groups (p=0.187). The multiple logistic analysis identified the asymmetry component (regression coefficient, 5.357; odds ratio, 212.158) and corneal eccentricity index (regression coefficient, -5.088; odds ratio, 0.006) as explanatory variables. The area under the receiver operating characteristic curve in the predictive equation-creation group was 0.946. The sensitivity and specificity in the validation group were 93.3% and 87.5%, respectively. CONCLUSIONS: The M-LVC discriminant prediction equation with the topography-equipped SS-OCT biometer was effective in detecting post-M-LVC eyes with high accuracy.

Impact of Masticatory Performance and the Tongue-Lip Motor Function on Incident Adverse Health Events in Patients with Metabolic Disease.

AIM: The present study aimed to determine whether decreased masticatory performance and tongue-lip motor function are associated with an increased incidence of adverse health events in patients with metabolic disease. METHODS: One thousand patients with metabolic diseases including diabetes, dyslipidemia, hypertension, and hyperuricemia were recruited. Masticatory performance was assessed using a gummy jelly test, wherein glucose elution from chewed gummy jelly was measured. The tongue-lip motor function was measured using repeatedly pronounced syllables per second. Their association with the incidence of adverse health events (a composite of all-cause death, cardiovascular disease, bone fracture, malignant neoplasm, pneumonia, and dementia) was investigated using the generalized propensity score (GPS) method. RESULTS: During a median follow-up period of 36.6 (interquartile range, 35.0-37.7) months, adverse health events were observed in 191 patients. The GPS adjusted dose-response function demonstrated that masticatory performance was inversely associated with the incidence of adverse health events. The 3-year incidence rate was 22.8% (95% confidence interval, 19.0-26.4%) for the lower quartile versus 13.6% (10.5-16.7%) for the upper quartile (P＜0.001). Similarly, the tongue-lip motor function was inversely associated with the incidence of adverse health events, with a 3-year incidence rate of 23.6% (20.0-27.0%) for the lower quartile versus 13.2% (10.4-15.9%) for the upper quartile (P＜0.001). CONCLUSIONS: Decreased masticatory performance and tongue-lip motor function were associated with an increased incidence of adverse health events in patients with metabolic disease.

Successful perioperative management of pheochromocytoma in a patient with Fontan circulation.

Pheochromocytoma (PCC) can adversely affect Fontan circulation. However, there are few reports on its perioperative management before and after PCC resection in Fontan patients. A 24-year-old female patient with congenitally corrected transposition of the great arteries, ventricular septal defect, and pulmonary atresia who had undergone Fontan palliation developed heart failure caused by PCC. The patient was pre-conditioned for PCC resection with heart failure treatment, alpha-blocker titration, and careful infusion, and had a good intraoperative and postoperative course with no complications. Postoperative catheter data showed improvements in systemic vascular resistance, cardiac output, and central venous pressure compared with preoperative data. There is no established preconditioning method for PCC resection in patients with Fontan circulation. Careful perioperative management based on an understanding of the features of the Fontan circulation can lead to better outcomes. Learning objective: Pheochromocytoma (PCC) can occur in patients with Fontan circulation. Preoperative management and the PCC itself can adversely affect Fontan circulation, highlighting the importance of suspecting PCCs in Fontan patients based on symptoms such as heart failure, worsening arrhythmias, and headache, and emphasizing careful perioperative management.

A case of malignant hypertension as a presentation of atypical hemolytic uremic syndrome.

INTRODUCTION: Malignant hypertension (mHTN) damages multiple target organs, including the kidneys. mHTN has been regarded as one of the causes of secondary thrombotic microangiopathy (TMA); however, a high prevalence of complement gene abnormalities was recently reported in cohorts of mHTN. CASE REPORT: We herein describe a 47-year-old male who presented with severe hypertension, renal failure (serum creatinine (sCr): 11.6 mg/dL), heart failure, retinal hemorrhage, hemolytic anemia, and thrombocytopenia. Renal biopsy findings were consistent with acute hypertensive nephrosclerosis. The patient was diagnosed with secondary TMA associated with mHTN. However, his previous medical history of TMA of unknown origin and family history of atypical hemolytic uremic syndrome (aHUS) suggested as aHUS presenting mHTN, and genetic testing revealed a pathogenic C3 mutation (p.I1157T). The patient required plasma exchange and hemodialysis for 2 weeks and was able to withdraw from dialysis by antihypertensive therapy without eculizumab. Renal function gradually improved to a sCr level of 2.7 mg/dL under antihypertensive therapy for 2 years after the event. There was no recurrence, and renal function was preserved throughout a 3-year follow-up. DISCUSSION: mHTN is a common presentation of aHUS. In cases of mHTN, abnormalities in complement-related genes may be involved in the development of the disease.

Evaluation of implantable collamer lens sizing developed by reviewing the horizontal compression-vault coefficient.

PURPOSE: To evaluate the implantable collamer lens (ICL)-sizing method using the partial regression coefficient of the implanted ICL size to review the conventional horizontal compression coefficient and match the results of clinical observation. SETTING: Nagoya Eye Clinic, Nagoya, Japan. DESIGN: Interventional case series. METHODS: Patients who underwent ICL V4c implantation to correct myopia and myopic astigmatism were enrolled. The stepwise multiple regression analysis used achieved vault as a dependent variable and preoperative biometric parameters as explanatory variables. The partial regression coefficient of the implanted ICL size was obtained to develop the optimal ICL-sizing formula, the Nakamura-Kojima formula version 3 (NK-formula V3). 85 eyes of 45 patients were implanted with an ICL size recommended by the NK-formula V3. At 3 months postoperatively, the achieved vault was measured using anterior segment optical coherence tomography to validate the NK-formula V3. RESULTS: The study enrolled 174 patients (174 eyes). The partial regression coefficient of the implanted ICL size adopted as the compression-vault coefficient in the multiple regression equation predicting the vault was 0.729. To validate the NK-formula V3, 77 (90.6%), 7 (8.2%), and 1 (1.2%) eyes were in the moderate-vault, low-vault, and high-vault categories, respectively. The mean difference between the achieved and predicted vaults was 0.064 ± 0.190 (range: -0.264 to 0.742) mm for the NK-formula V3 and 0.176 ± 0.217 (range: -0.254 to 0.907) mm for the NK-formula V2. CONCLUSIONS: As in vivo coefficient measurement experiments are not possible, the partial regression coefficient is the best option for developing a formula to predict the optimal ICL size.

Suppression of tumor metastasis by a RECK-activating small molecule.

RECK encodes a membrane-anchored protease-regulator which is often downregulated in a wide variety of cancers, and reduced RECK expression often correlates with poorer prognoses. In mouse models, forced expression of RECK in tumor xenografts results in suppression of tumor angiogenesis, invasion, and metastasis. RECK mutations, however, are rare in cancer genomes, suggesting that agents that re-activate dormant RECK may be of clinical value. We found a potent RECK-inducer, DSK638, that inhibits spontaneous lung metastasis in our mouse xenograft model. Induction of RECK expression involves SP1 sites in its promoter and may be mediated by KLF2. DSK638 also upregulates MXI1, an endogenous MYC-antagonist, and inhibition of metastasis by DSK638 is dependent on both RECK and MXI1. This study demonstrates the utility of our approach (using a simple reporter assay followed by multiple phenotypic assays) and DSK638 itself (as a reference compound) in finding potential metastasis-suppressing drugs.

Association of insulin treatment with gastric residue during an esophagogastroduodenoscopy.

The purpose of this study was to investigate the association of glycemic control and diabetes treatment to gastric residue observed during an esophagogastroduodenoscopy. Among 6,592 individuals who had esophagogastroduodenoscopy at our clinic between 2003 and 2019, we retrospectively and longitudinally identified those who had gastric residue during an esophagogastroduodenoscopy. Other data collected were age, sex, diagnosis of diabetes, glycated hemoglobin and diabetes medication. Cox proportional hazards models were used to assess the association of these data with the occurrence of gastric residue. To the best of our knowledge, this is the first retrospective cohort study finding that undergoing insulin treatment is a risk factor for gastric residue independent of age, sex and diabetes or glycated hemoglobin.

Life-threatening cardiac arrhythmia and sudden death during electronic gaming: An international case series and systematic review.

BACKGROUND: Electronic gaming has recently been reported as a precipitant of life-threatening cardiac arrhythmia in susceptible individuals. OBJECTIVE: The purpose of this study was to describe the population at risk, the nature of cardiac events, and the type of game linked to cardiac arrhythmia associated with electronic gaming. METHODS: A multisite international case series of suspected or proven cardiac arrhythmia during electronic gaming in children and a systematic review of the literature were performed. RESULTS: Twenty-two patients (18 in the case series and 4 via systematic review; aged 7-16 years; 19 males [86%]) were identified as having experienced suspected or proven ventricular arrhythmia during electronic gaming; 6 (27%) had experienced cardiac arrest, and 4 (18%) died suddenly. A proarrhythmic cardiac diagnosis was known in 7 (31%) patients before their gaming event and was established afterward in 12 (54%). Ten patients (45%) had catecholaminergic polymorphic ventricular tachycardia, 4 (18%) had long QT syndrome, 2 (9%) were post-congenital cardiac surgery, 2 (9%) had "idiopathic" ventricular fibrillation, and 1 (after Kawasaki disease) had coronary ischemia. In 3 patients (14%), including 2 who died, the diagnosis remains unknown. In 13 (59%) patients for whom the electronic game details were known, 8 (62%) were war games. CONCLUSION: Electronic gaming can precipitate lethal cardiac arrhythmias in susceptible children. The incidence appears to be low, but syncope in this setting should be investigated thoroughly. In children with proarrhythmic cardiac conditions, electronic war games in particular are a potent arrhythmic trigger.

Synergistic association of the copper/zinc ratio under inflammatory conditions with diabetic kidney disease in patients with type 2 diabetes: The Asahi Diabetes Complications Study.

AIMS/INTRODUCTION: We aimed to study the relationships among the copper (Cu)/zinc (Zn) ratio, inflammatory biomarkers, and the prevalence of diabetic kidney disease (DKD) in patients with type 2 diabetes. MATERIALS AND METHODS: A cross-sectional study was performed on 651 patients with type 2 diabetes. DKD was defined as a urinary albumin-to-creatinine ratio of ≥30 mg/g creatinine and/or an estimated glomerular filtration rate using cystatin C of < 60 mL/min/1.73 m2 . Areas under the curves (AUCs), cutoff values, and thresholds for detecting DKD were determined for the Cu/Zn ratio, soluble tumor necrosis factor-α receptor 1 (sTNFαR1), and high-sensitivity C-reactive protein (hsCRP). Patients were categorized by each cutoff value of sTNFαR1 and the Cu/Zn ratio. Odds ratios (ORs) and biological interactions for the prevalence of DKD were determined. RESULTS: DKD was identified in 220 patients. AUC/optimal cutoff values were 0.777/1300 pg/mL for sTNFαR1, 0.603/1.1648 for the Cu/Zn ratio, and 0.582/305 ng/mL for hsCRP. The ORs for DKD were higher, but not significantly, in the sTNFαR1 < 1300 and Cu/Zn ≥ 1.1648 group, significantly higher in the sTNFαR1 ≥ 1300 and Cu/Zn < 1.1648 group (P < 0.0001), and further synergistically elevated in the sTNFαR1 ≥ 1300 and Cu/Zn ≥ 1.1648 group (P < 0.0001) compared with the sTNFαR1 < 1300 and Cu/Zn < 1.1648 group after multivariable adjustment. Levels of sTNFαR1 were significantly higher in the sTNFαR1 ≥ 1300 and Cu/Zn ≥ 1.1648 group than in the sTNFαR1 ≥ 1300 and Cu/Zn < 1.1648 group (P = 0.0006). CONCLUSIONS: Under an inflammatory initiation signal of elevated serum sTNFαR1 levels, an increase in the Cu/Zn ratio may further exacerbate inflammation and is synergistically associated with a high prevalence of DKD in patients with type 2 diabetes.

Prediction of the trabecular iris angle after posterior chamber phakic intraocular lens implantation.

PURPOSE: To create an equation for predicting the trabecular iris angle (TIA) and to verify its accuracy after implantable collamer lens (ICL) implantation. SETTING: Nagoya Eye Clinic, Nagoya, Japan. DESIGN: Retrospective evaluation of a screening approach. METHODS: 174 eyes (174 patients) that underwent ICL implantation were included. Patients were randomly assigned to the prediction equation group (116 eyes) or verification group (58 eyes). Anterior segment optical coherence tomography (AS-OCT) (CASIA2 TOMEY) was performed before and 3 months after ICL surgery. For the prediction group, a prediction equation was created with the preoperative AS-OCT parameters and ICL size as independent variables and the postoperative anterior chamber depth (ACD) as the dependent variable. Then, by applying the predicted post-ACD and preoperative AS-OCT parameters as independent variables and TIA after ICL surgery as the dependent variable, a prediction equation was created to predict the postoperative TIA (post-TIA) after ICL surgery. Each prediction equation was created using stepwise multiple regression analysis, and its accuracy was verified by a Bland-Altman plot in the verification group. RESULTS: The explanatory variables (standardized partial regression coefficient) selected in the post-TIA prediction equation were post-ACD (0.629), TIA750 (0.563), iris curvature (0.353), pupil diameter (-0.281), iris area (-0.249), and trabecular iris space area 250 (-0.171) (R2 = 0.646) (n = 116). There were no clinically significant systematic errors between measured and predictive post-TIA values in the verification group (n = 58). The mean absolute prediction error was 3.43 ± 2.22 degrees. CONCLUSIONS: Post-TIA was accurately predicted from the predicted post-ACD and other preoperative AS-OCT parameters.

Association of obesity, diabetes, and physical frailty with dental and tongue-lip motor dysfunctions in patients with metabolic disease.

OBJECTIVE: This study aimed to reveal the clinical features associated with decreased dental (or shearing/crushing) and tongue-lip motor functions in patients with metabolic diseases. METHODS: One thousand patients with metabolic diseases including diabetes, dyslipidemia, hypertension, and hyperuricemia were recruited. Dental function was assessed with a gummy jelly test, wherein glucose elution from a chewed gummy jelly was measured. Tongue-lip motor function was measured as repeatedly pronounced syllables per second. The association of clinical variables with the two functions was analyzed using multivariate linear regression models. RESULTS: The mean measurement of dental function was 202 ± 73 mg/dL, and that of tongue-lip motor function was 5.5 ± 1.0 times/s. Clinical variables independently associated with dental function (mg/dL) were age (adjusted regression coefficient ß = -9.8 per standard deviation [SD]), smoking (ß = -14.4 and -25.9 for past and current smoking, respectively), body mass index (BMI) 25-30 and ≥30 versus 20-25 kg/m2 (ß = -14.7 and -23.1, respectively), diabetes (ß = -11.9), hemoglobin A1c level ≥64 mmol/mol (ß = -14.6), gait speed (ß = 6.2 per SD), and handgrip strength (ß = 7.5 and 7.7 per SD for males and females, respectively) (all P < 0.05). Clinical variables independently associated with tongue-lip motor function (times/s) were age (ß = -0.31 per SD), BMI ≥ 30 versus 20-25 kg/m2 (ß = -0.24), diabetes (ß = -0.22), dyslipidemia (ß = 0.16), gait speed (ß = 0.12 per SD), and handgrip strength (ß = 0.18 and 0.13 per SD for males and females, respectively) (all P < 0.05). CONCLUSIONS: Obesity, diabetes, physical frailty, and old age were shared risk factors for decreased dental and tongue-lip motor functions in patients with metabolic diseases.

Electrocardiographic features of arrhythmogenic right ventricular cardiomyopathy in school-aged children.

It can be difficult to distinguish children with early-stage arrhythmogenic right ventricular cardiomyopathy (ARVC) from those with benign premature ventricular contraction (PVC). We retrospectively evaluated six school-aged children with ARVC and compared with those of 20 with benign PVC. The median age at initial presentation was 11.4 and 10.2 years in ARVC and benign PVC, respectively. None of the ARVC patients fulfilled the diagnostic criteria of ARVC at initial presentation. At ARVC diagnosis, the treadmill exercise test and Holter monitoring showed provoked PVC during exercise and pleomorphic PVC in all ARVC cases, respectively. During the observation period, terminal activation duration (TAD) was prolonged in all ARVC patients. In addition, ΔTAD (5.5 [3-10] ms) were significantly longer than those with benign PVC (p < 0.001). A new notched S-wave in V1 appeared in four (67%) ARVC patients, who had myocardial abnormalities in the right ventricle, and in zero benign PVC. Our electrocardiographic findings, such as provoked PVC during exercise, pleomorphic PVC, prolonged TAD, and a new notched S-wave in V1 could contribute to the early detection of ARVC in school-aged children.

Comparison of Corneal Biomechanical Properties and Corneal Tomography Between Customized and Accelerated Corneal Crosslinking in Eyes with Keratoconus.

PURPOSE: To compare the changes in corneal biomechanical properties and corneal tomography between transepithelial customized corneal crosslinking (C-CXL) and epithelium-off accelerated corneal crosslinking (A-CXL) in eyes with keratoconus. METHODS: Twenty eyes in 20 consecutive patients who underwent C-CXL (C-CXL group) and 20 eyes in 20 patients who underwent A-CXL (A-CXL group) were included in this retrospective comparative study. The corneal biomechanical properties were analyzed using a Scheimpflug-based tonometer, and all corneas were examined by anterior segment optical coherence tomography (AS-OCT) before and 3 months after surgery. The corneal biomechanical parameters analyzed were the maximum inverse radius, deformation amplitude (DA) ratio max (2 mm), stiffness parameter at applanation 1, and integrated radius. The AS-OCT parameters analyzed included average keratometry, corneal astigmatism, maximum keratometry reading (Kmax), higher-order irregularity, and asymmetry. RESULTS: In the C-CXL group, there were significant improvements in biomechanical parameters, including the maximum inverse radius, the DA ratio max (2 mm), and the integrated radius after surgery (P = 0.037, P = 0.002, and P = 0.003, respectively). In the C-CXL group, there was a significant decrease in the Kmax, higher-order irregularity, and asymmetry components (P = 0.014, P = 0.008, and P = 0.016, respectively). The biomechanical properties and AS-OCT parameters did not change significantly in the A-CXL group after surgery. According to multiple regression analyses, C-CXL had a greater effect than A-CXL in improving the maximum inverse radius, DA ratio max (2 mm), integrated radius, Kmax, asymmetry component, and higher-order irregularity component. CONCLUSIONS: C-CXL might improve the biomechanical properties and irregular shape of the cornea from the early postoperative period to a greater extent than A-CXL.

The Isoquinoline-Sulfonamide Compound H-1337 Attenuates SU5416/Hypoxia-Induced Pulmonary Arterial Hypertension in Rats.

Pulmonary arterial hypertension (PAH) is characterized by elevated pulmonary arterial pressure and right heart failure. Selective pulmonary vasodilators have improved the prognosis of PAH; however, they are not able to reverse pulmonary vascular remodeling. Therefore, a search for new treatment agents is required. H-1337 is an isoquinoline-sulfonamide compound that inhibits multiple serine/threonine kinases, including Rho-associated protein kinase (ROCK) and mammalian target of rapamycin (mTOR). Here, we investigated the effects of H-1337 on pulmonary hypertension and remodeling in the pulmonary vasculature and right ventricle in experimental PAH induced by SU5416 and hypoxia exposure. H-1337 and H-1337M1 exerted inhibitory effects on ROCK and Akt. H-1337 inhibited the phosphorylation of myosin light chain and mTOR and suppressed the proliferation of smooth muscle cells in vitro. H-1337 treatment also suppressed the phosphorylation of myosin light chain and mTOR in the pulmonary vasculature and decreased right ventricular systolic pressure and the extent of occlusive pulmonary vascular lesions. Furthermore, H-1337 suppressed aggravation of right ventricle hypertrophy. In conclusion, our data demonstrated that inhibition of ROCK and mTOR pathways with H-1337 suppressed the progression of pulmonary vascular remodeling, pulmonary hypertension, and right ventricular remodeling.

Long-term In Vivo Stability of Posterior Chamber Phakic Intraocular Lens: Properties and Light Transmission Characteristics of Explants.

PURPOSE: To evaluate the in vivo durability of the surface and optical properties of the implantable Collamer lens (ICL). DESIGN: Retrospective case series. METHODS: We included patients who developed cataracts after having undergone ICL implantation from March 2003 to May 2014 and underwent ICL explantation followed by cataract surgery from March 2017 to December 2019 at the Nagoya Eye Clinic. ICL explants were submitted to Chukyo Medical Co, Ltd (Nagoya City, Japan) for laboratory analysis using ultraviolet-visible light spectroscopy, light microscopy (LM), and scanning electron microscopy. Patients' demographic and clinical data were collected and reviewed. RESULTS: Thirteen eyes from 10 patients were studied. The average age at ICL explantation was 50.5 ± 8.5 years (range, 34.5-66.3 years). The average length of ICL stay in the eye (from implantation to explantation) was 10.5 ± 2.7 years (range, 4.4-13.7 years). No opacification or coloring of the ICL explants was observed by LM. The ICL explants showed almost the same light transmittance as that of unused ICLs. Scanning electron microscopy revealed no irregularities at the surface of the center and periphery of the optic and haptic footplate. The positioning holes did not show any deposition. CONCLUSION: The ICLs remained in-eye for >10 years without any deterioration in the surface and optical properties of the ICL, despite their contact with the ciliary body and iris tissues and the continuous interaction with the aqueous humor components. The present study shows long-term in vivo stability of the ICL.

Optimization of implantable collamer lens sizing based on swept-source anterior segment optical coherence tomography.

PURPOSE: To optimize the implantable collamer lens (ICL) sizing method using anterior segment optical coherence tomography (AS-OCT). SETTING: Nagoya Eye Clinic, Nagoya, Japan. DESIGN: Interventional case series. METHODS: A stepwise multiple regression analysis was performed using the optimal ICL size as a dependent variable and preoperative AS-OCT parameters as explanatory variables for 81 eyes of 41 patients, and the NK-formula version 2 (NK-formula V2) was obtained. Thereafter, 68 eyes of 42 patients were implanted with the ICLs selected as closest to the optimal ICL size calculated by the NK-formula V2. At 3 months postoperatively, the achieved vault was measured by AS-OCT to evaluate the optimization of the sizing method. RESULTS: The anterior chamber width (ACW) and crystalline lens rise were selected as significant parameters for the regression model (R = 0.61, P < .001), as with the previous NK-formula. Of the 68 eyes, 36 patients/62 eyes (91.2%), 5 patients/5 eyes (7.3%), and 1 patient/1 eye (1.5%) were in the moderate, high, and low vault categories, respectively. In the 68 eyes, the vault showed no correlation with the optimal ICL size (R = 0.0185, P = .269), whereas the vault showed a negative correlation with the optimal ICL size in both the 12.6 mm ICL subgroup (R = -0.409, P = .0088) and the 13.2 mm ICL subgroup (R = -0.818, P = .0013). CONCLUSIONS: This optimization approach showed excellent ability to select an appropriate ICL to be implanted regardless of the value of other ocular parameters and age, except ACW.

Causes of death and estimated life expectancy among people with diabetes: A retrospective cohort study in a diabetes clinic.

We sought to estimate the exact causes of death, mortality rate and life expectancy of diabetes patients by analyzing death records in a diabetes specialist clinic in Japan. Of the 6,140 participants included in our analysis, the average age was 58.1 years and 77% were men. A total of 261 deaths were recorded during the total follow-up period of 24,079 total person-years. The leading causes of death were cancer, heart diseases and cerebrovascular diseases. Using a life table prepared from the mortality rates estimated with the exponential distribution model, a life expectancy at 40 years was 39.2 years (95% confidence interval 37.9-40.2 years) for men and 43.6 years (95% confidence interval 41.8-45.3 years) for women. Although the present results must be interpreted with caution, compared with populations with diabetes surveyed during similar periods by the Japan Diabetes Society, our diabetes patients had similar ranking of the causes of death.

A rare case of truncus arteriosus Van Praagh type A3: Prenatal diagnosis and postnatal management.

Truncus arteriosus (TrA) type A3, according to the Van Praagh (VP) classification, cannot be classified under the Collett and Edwards (C-E) system. In this rare anomaly, postnatal closure of the ductus arteriosus can cause unilateral pulmonary artery obstruction; hence, prenatal diagnosis and early confirmatory postnatal diagnosis are important. This case was referred to our hospital for suspected fetal heart disease at 29 weeks' gestation. TrA C-E type 1 was diagnosed by fetal echocardiography, with a right-sided aortic arch, absent inferior vena cava, and azygos continuation. The neonate was delivered vaginally at 41 weeks' gestation. Postnatal echocardiography showed a right-sided aortic arch with the right pulmonary artery originating from the common arterial trunk and the left pulmonary artery originating from the brachiocephalic artery. The diagnosis was TrA VP type A3, with a right-sided aortic arch and left-sided ductus arteriosus. Patency of the left-sided ductus arteriosus was maintained with prostaglandin E1.alpha-cyclodextrin. Right pulmonary artery banding was performed 3 days after birth. The Rastelli procedure was performed when the patient was 2 months old and weighed 4.2 kg. Delayed diagnosis of VP type A3 can cause unilateral pulmonary artery disconnection; hence, timely and accurate diagnosis is warranted to ensure stable disease management. .

Posterior Chamber Phakic Intraocular Lens Implantation for the Correction of Myopia and Myopic Astigmatism: A Retrospective 10-Year Follow-up Study.

PURPOSE: To assess the 10-year clinical outcomes of implantable collamer lens (ICL) implantation for myopia and astigmatism. DESIGN: Retrospective observational case series. METHODS: This study included 114 eyes of 61 patients who underwent ICL implantation for correction of myopia and myopic astigmatism. We assessed the safety, efficacy, predictability, stability, and adverse events preoperatively, at 6 months (106 eyes) and 1 (94 eyes), 3 (58 eyes), 5 (65 eyes), 8 (89 eyes), and 10 (70 eyes) years postoperatively. Only the eyes with clinical data available at each follow-up time were analyzed. RESULTS: The mean logMAR uncorrected and corrected distance visual acuities were -0.01 ± 0.24 and -0.18 ± 0.07 at 10 years postsurgery. The mean indices for safety and efficacy were 0.88 ± 0.15 and 0.66 ± 0.26, respectively. At 10 years postsurgery, 71.4% and 87.1% of the eyes were within 0.5 and 1.0 diopters (D), respectively, of the attempted spherical equivalent correction. The mean intraocular pressure was 13.1 ± 2.4 mmHg preoperatively and 13.1 ± 2.9 mmHg at 10 years postoperatively. The mean endothelial cell loss was 5.3% at 10 years postsurgery. Twelve of 114 eyes (10.5%) developed anterior subcapsular cataract during 5-10 years' follow-up; among these, 4 eyes (3.5%) were symptomatic and ICL explantation and phacoemulsification surgery were performed. No vision-threatening complications occurred during the observation period. CONCLUSION: ICL implantation offered good overall outcomes in all measures of safety, efficacy, predictability, and stability for the correction of myopia and myopic astigmatism throughout a long-term follow-up period of 10 years.

Control-matched comparison of refractive and visual outcomes between small incision lenticule extraction and femtosecond laser-assisted LASIK.

PURPOSE: This retrospective case-matched study aimed to compare visual and refractive outcomes between small incision lenticule extraction (SMILE) and LASIK. PATIENTS AND METHODS: Patients who underwent SMILE (34 eyes of 23 patients) or LASIK (34 eyes of 24 patients) were enrolled and matched according to preoperative manifest refractive spherical equivalents. The mean preoperative manifest refractive spherical equivalent was -4.69±0.6 and -4.67±0.64 D in the SMILE and LASIK groups, respectively. The safety, efficacy, and predictability were compared 3 months after surgery. Changes in corneal refractive power from the center to peripheral points and their maintenance ratios were analyzed and compared between the two groups. RESULTS: In the SMILE and LASIK groups, 82.4% and 85.3% of patients, respectively, achieved 20/13 or better uncorrected distance visual acuity (p=1.00). There were no eyes that lost two or more lines of corrected distance visual acuity in either group. The maintenance ratios of corneal refractive power changes at the peripheral points in the SMILE group were significantly higher than those in the LASIK group (p<0.05). CONCLUSION: Both groups achieved similar high efficacy and safety. SMILE surgery resulted in higher refractive power correction in the peripheral cornea than LASIK surgery.
