Purpose To assess the association of dietary saturated fatty acid (SFA) intake with the presence of early AMD in a Japanese population. Methods The population-based Tsuruoka Metabolomics Cohort Study enrolled general population individuals aged 35 to 74 years from among participants in annual health check-up programs that included fundus photographs in Tsuruoka, Japan. A total of 4010 individuals participated in the baseline survey. After excluding nonresponders to a dietary survey and participants with suboptimal fundus image quality, 3988 participants (median age, 62.4 years) were included in this cross-sectional analysis. Dietary intake was assessed by a validated food frequency questionnaire. Fatty acids intake was adjusted for total energy intake by the residuals method. The association between fatty acid intake and presence of early AMD was assessed by logistic regression models. Results Median daily SFA intake was 11.3 g (interquartile range, 9.6, 13.0 g). After adjustments for potential confounding factors, participants in the highest quartile of SFA intake were less likely to have early AMD, compared with the lowest quartile (odds ratio, 0.71; 95% confidence interval 0.52-0.96). A significant trend for decreased risk of early AMD with increasing SFA intake was noted (P = 0.011). There was no significant association between poly-unsaturated fatty acid (PUFA) including n3-PUFA intake and early AMD. Conclusions We found that increased SFA intake was associated with reduced risk of early AMD in a Japanese population with low SFA intake. Adequate fatty acid intake may be required to maintain retinal homeostasis and prevent AMD.Purpose To determine the association of corneal sensitivity and tear functions on the prognosis of eyes after posttraumatic recurrent corneal erosion syndrome (RCES). Methods Patients were enrolled retrospectively and had unilateral RCES and a history of ocular surface trauma. A corneal sensitivity test and tear function test (tear break-up time and Schirmer test) were performed at three time points (month 1 to month 3, month 3 to month 6, and month 6 to month 12). Depending on the number of recurrences during the follow-up, patients were divided into group A (n > 2) or group B (n = 2). A comparison between diseased and normal fellow eyes in each patient was performed. Results A total of 31 patients were enrolled and divided into group A (n = 14) and group B (n = 17). The mean age was 40.3 ± 12.2 years, whereas the mean follow-up was 28.0 ± 3.6 months. During the study period, corneal sensitivity, tear break-up time, and the Schirmer test results were all lower in diseased eyes than in normal fellow eyes in both groups. Compared to the first time point, recovery of corneal sensitivity and the Schirmer test values were observed in diseased eyes in group B at the second and third time points. Conclusions Poor corneal sensitivity and tear function are associated with posttraumatic RCES. Recovery of corneal sensitivity and tear function may be associated with a reduction of recurrence in eyes with posttraumatic RCES.Investigation of solid electrolyte interphases (SEIs) on negative electrode surfaces is essential to improve the stable charge-discharge performance of rechargeable lithium-air batteries (Li-O2 batteries). In this study, a direct investigation of SEI films is conducted using analytical transmission electron microscopy (TEM). Selleckchem Tacrolimus A thin Cu specimen is pre-fabricated for TEM observation, and is utilised as a model substrate for SEI formation. The electrochemical cell constructed using dissolved oxygen in the electrolyte exhibits a greater electrochemical overpotential during the Li-metal deposition process than that constructed with a pristine electrolyte. This suggests that different electrochemical passivation features occur in each different electrochemical cell. TEM observation confirms that the surface film formed by O2 dissolute electrolyte is a polycrystalline Li2O film with a thickness of approximately 5 nm, whereas the film formed by the pristine electrolyte is organic-based, amorphous-like, and 20-50 nm thick. The dissolved oxygen molecules are more easily reduced than the components of the electrolyte, leading to the formation of Li2O as a stable passivation SEI film, which is expected to exhibit good charge-discharge features during the operation of the Li-O2 battery. © The Author(s) 2020.

While warfarin anticoagulation reduces this risk, its use increases the risk of bleeding. We sought to estimate the rate of thromboembolic and bleeding complications among patients with MHVs at a tertiary hospital in Botswana. Factors associated with bleeding and thromboembolic complications are also described. METHODS This retrospective cohort study involved a cohort of patients with MHV at Princess Marina Hospital who were operated on before September 2017. The study documented bleeding and thromboembolic events since the valve replacement, patients' demographic information, co-existing medical conditions, drug history and details of valve replacement. Using the recent international normalised ratio (INR) results, each patient's time in therapeutic range (TTR) was calculated to assess the level of anticoagulation control. RESULTS The study enrolled 142 patients with a mean (SD) age of 42 (12) years and a median (IQR) duration since valve replacement of four years (1.8-10.0). The median (IQR) TTR was 29.8% (14.1-51.0) and only 14.8% of the patients had an optimal anticoagulation control. The rates of major bleeding and thromboembolic complications were 1.5 per 100 person-years and 2.80 per 100 person-years, respectively. A longer duration of warfarin use was associated with an increased risk of both bleeding (p = 0.008) and thromboembolic complications (p = 0.01). CONCLUSIONS Bleeding and thromboembolic complications were common in MHV prosthesis patients in this study. Long duration of anticoagulation, albeit sub-optimal control, was a risk factor for bleeding and thromboembolic complications in these patients. Therefore, long-term efforts are necessary to address these complications and possibly improve the quality of life of these patients.
