Microforceps-Assisted Transscleral Fixation of Intraocular Lens.

PURPOSE: We present a novel technique for intraocular lens (IOL) fixation. The technique can be used on single-piece acrylic IOLs and can manage the patients who are either aphakia or with a dislocated IOL. METHODS: One end of Gore-Tex suture is tied into the optic-haptic junction of the IOL. Another end is fixated in the scleral wall. The single sclerotomy and double sclerotomies settings can be applied to different situations. RESULTS: Twelve eyes received this procedure. After a follow-up period of up to 20 months, the IOLs were well centered. CONCLUSION: The technique is a reliable method for scleral fixation of IOLs, which can be applied on the widely used single-piece acrylic IOLs. In our experience, it is reproducible and rarely cause complications.

Prevalence of eye and adnexal disorders among elderly inmates in Taiwan prisons.

BACKGROUND: Prisoner health is a topic of significant importance; however, it has received limited attention in epidemiological studies, likely because of challenges in obtaining relevant data. Specifically, research on ocular disorders among elderly prisoners is lacking. Thus, the aim of this study was to evaluate the prevalence of disorders of the eye and adnexa among elderly prisoners in Taiwan. METHODS: We investigated the presence of eye and adnexal disorders in elderly prisoners in Taiwan using data from the Taiwan National Health Insurance Research Database. The ocular disorders were identified using the appropriate disease codes in the International Classification of Diseases, 9th revision Clinical Modification (codes 360-379). In addition, the most common types of eye and adnexal disorders among the prisoners were identified. RESULTS: A total of 2215 elderly prisoners (age ≥ 65 years; 2073 men and 142 women) were examined. The prevalence of eye and adnexal disorders among the prisoners was 18.87%. The elderly female prisoners exhibited a higher prevalence of eye and adnexal disorders than the elderly male prisoners. The most common disorders were disorders of the conjunctiva, cataract, and disorders of the lacrimal system. CONCLUSIONS: A considerable proportion of elderly prisoners have disorders of the eye and adnexa. The overall quality of life of elderly prisoners can be improved by addressing their visual health, which contributes to the fulfillment of their basic human rights.

How renal toxins respond to renal function deterioration and oral toxic adsorbent in pH-controlled releasing capsule.

The number of patients with chronic kidney disease (CKD) is increasing. Oral toxin adsorbents may provide some value. Several uremic toxins, including indoxyl sulfate (IS), p-cresol (PCS), acrolein, per- and poly-fluoroalkyl substances (PFAS), and inflammation markers (interleukin 6 [IL-6] and tumor necrosis factor [TNF]-alpha) have been shown to be related to CKD progression. A total of 81 patients taking oral activated charcoal toxin adsorbents (AC-134), which were embedded in capsules that dissolved in the terminal ileum, three times a day for 1 month, were recruited. The renal function, hemoglobulin (Hb), inflammation markers, three PFAS (PFOA, PFOS, and PFNA), and acrolein were quantified. Compared with the baseline, an improved glomerular filtration rate (GFR) and significantly lower acrolein were noted. Furthermore, the CKD stage 4 and 5 group had significantly higher concentrations of IS, PCS, IL-6, and TNF but lower levels of Hb and PFAS compared with the CKD Stage 3 group at baseline and after the intervention. Hb was increased only in the CKD Stage 3 group after the trial (p = .032). Acrolein did not differ between the different CKD stage groups. Patients with improved GFR (responders) (about 77%) and nonresponders had similar baseline GFR. Responders had higher acrolein and PFOA levels throughout the study and a more significant reduction in acrolein, indicating a better digestion function. Both the higher PFOA and lower acrolein may be related to improved eGFR (and possibly to improvements in proteinuria, which we did not measure. Proteinuria is associated with PFAS loss in the urine), AC-134 showed the potential to improve the GFR and decrease acrolein, which might better indicate renal function change. Future studies are needed with longer follow-ups.

Baseline characteristics and treatment response predictive of nAMD outcomes with ranibizumab therapy in treatment-naive patients: the RACER subgroup analysis.

BACKGROUND: The Ranibizumab AMD Clinical Efficacy Study (RACER) conducted in treatment-naive adult Taiwanese patients with neovascular age-related macular degeneration (nAMD) suggested the importance of early and intensive dosing of ranibizumab for optimal treatment outcomes. This subgroup analysis aims to provide clinical information on treatment response that can potentially guide on maintaining the treatment or switching anti-VEGF agents in the real-world setting. METHODS: Visual acuity (VA) and central retinal thickness (CRT) were assessed in the RACER subgroup population. Subgroup analysis sets were categorised based on: (1) baseline best-corrected VA (BCVA; ≤ 48 and > 48 letters); (2) baseline CRT (≤ 325 or > 325 µm); and (3) treatment response after three monthly initial injections: < or ≥ 5-letter gain in BCVA and reduction of < or ≥ 50 µm in CRT. RESULTS: Patient age, sex, nAMD duration and number of ranibizumab injections did not differ significantly between the treatment subgroups. Poor baseline BCVA (≤ 48 letters) and baseline CRT severity (> 325 µm) were predictors of maximum BCVA gains (9.6 ± 12.9 letters [95%CI: 6.3 to 12.9] and 5.1 ± 18.3 letters [95%CI: - 0.5 to 10.8] at Months 3 and 12, respectively) and better CRT reductions (- 127.6 ± 104.2 µm and - 104.2 ± 107.4 µm at Months 3 and 12, respectively; both P < 0.001). For the subgroup showing favourable treatment improvement with BCVA gains ≥ 5 letters after three monthly initial injections, 75.6% of patients maintained follow-up at Month 12 with a mean of 6.5 ± 14.3 letter gains (95% CI: 1.2 to 11.7). The BCVA gains < 5-letter subgroup nevertheless had stable BCVA (0.4 ± 12.1 letter gains) and CRT (- 41.9 ± 61.2 µm) at Month 12, respectively. In the subgroup with ≥ 50 µm CRT reduction after three monthly initial injections, there are significantly higher BCVA improvements vs. the < 50 µm CRT reduction subgroup at Month 3 (5.0 ± 8.6 letter gains vs. 1.5 ± 11.6 letter gains, respectively; intergroup P = 0.005). CONCLUSION: Lower baseline BCVA and higher baseline CRT were associated with BCVA gains and CRT reductions throughout the 12-month study period. Early CRT improvements after three monthly initial injections were associated with BCVA gains as early as Month 3.

Risk factors for anisometropia in schoolchildren: A population-based, longitudinal cohort study.

PURPOSE: To investigate the incidence rate and risk factors for anisometropia among young schoolchildren. METHODS: A population-based cohort study, the Myopia Investigation Study in Taipei, was conducted in primary schools in Taipei City. Children were recruited for biannual comprehensive eye examinations over 2 years. Cycloplegic autorefraction and slit lamp examinations were performed biannually. Data on demographic information, parental history, lifestyle and near-work activities were collected using parent-administered questionnaires at the first and final visits. Anisometropia was defined as ≥1 D difference in the spherical equivalent (SE) refractive error. RESULTS: A total of 7035 8-year-old children completed the 2-year follow-up evaluations. The average annual incidence of anisometropia was 3.8%. Multivariable logistic regression analysis revealed that baseline SE (odds ratio [OR]: 0.87 95% CI: 0.80-0.95) and female sex (OR: 1.24, 95% confidence interval [CI]: 1.02-1.50) were significantly associated with incident anisometropia. Among lifestyle risk factors, spending <1 h per day in after-school outdoor activities on weekdays (OR: 1.38, 95% CI: 1.08-1.76) and performing near work at a distance <30 cm (OR: 1.33, 95% CI: 1.08-1.64) were significantly associated with an increased risk of incident anisometropia. In the multiple linear regression analysis, the inter-eye difference in SE increased significantly in children performing near work at distances <30 cm (adjusted ß = 0.03; p = 0.02). CONCLUSIONS: This study indicated the annual incidence of anisometropia in Taiwanese schoolchildren. Less time spent outdoors and shorter eye-to-object distances during near work increased the risk of incident anisometropia.

Proteomic Profiling of Aqueous Humor Exosomes from Age-related Macular Degeneration Patients.

Purpose: The alteration of the exosomal proteins in the aqueous humor (AH) is linked to the development of eye diseases. The goal of this study was to examine the exosomal protein profile of patients with age-related macular degeneration (AMD) to better understand their role in the pathogenesis of AMD. Methods: Exosomes were isolated from the AH of 28 AMD and 25 control eyes. The quality, concentration, and size distribution of exosomes were measured using a nanoparticle tracking analysis system (NTA). Total exosomal proteins from each sample were purified and digested with trypsin for liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis. Results: Based on LC-MS/MS analysis, we got 105 exosomal peptides from AMD and control patients. Gene ontology (GO) analysis in the biology process revealed that exosomal proteins of AMD were enriched in the lipoprotein metabolic process. T-test analysis revealed six exosomal proteins in patients with AMD were significantly different from controls. Comparing the exosomal protein profile of AMD patients who were receiving anti-VEGF therapy, we observed the amount of two proteins decreased with the duration of the anti-VEGF treatment time. Conclusions: In this study, we successfully isolated and purified AH exosomes. Our results provide pioneering findings for the exosomal protein profile in AMD development and under therapy. These unique proteins could be the new targets for drug discovery or biological markers for evaluating therapeutic efficacy.

Ranibizumab reimbursement and treatment patterns for neovascular age-related macular degeneration in Taiwan - Results from the 12-month, observational RENOWNED study.

BACKGROUND: The RENOWNED study investigated the treatment patterns, real-world effectiveness and safety of ranibizumab in Taiwanese patients with neovascular age-related macular degeneration (nAMD) treated with ranibizumab 0.5 mg in accordance with the first reimbursement scheme effective from 2012 to 2014. METHODS: This study was a Phase IV, 12-month, open-label, prospective, observational study conducted in Taiwan. Patients with visual impairment due to nAMD initiating treatment with ranibizumab 0.5 mg were included. The primary endpoint was mean change in best-corrected visual acuity (BCVA) from Baseline at Month 3. RESULTS: Overall, 202 patients with nAMD were included. Mean (standard deviation [SD]) BCVA Early Treatment Diabetic Retinopathy Study letters improved from Baseline (49.6 [21.5] letters) at Month 3 (+4.9 [11.8], P < 0.0001), and at Month 12 (+3.5 [14.1], P = 0.0043). The proportion of patients with nAMD who lost ≥5 letters at Months 3 and 12 was 13.6% (n = 27) and 26.6% (n = 37), respectively. Mean (SD) central retinal thickness decreased from Baseline (320.1 [127.2] µm) with a mean reduction of 49.1 (107.3) µm at Month 3 (P < 0.0001), but was not significant at Month 12 with a mean reduction of 11.6 (115.6) µm (P = 0.2861). Mean (SD) number of ranibizumab injections over 12 months was 3.1 (1.0). A mean treatment interval of 109.5 days was observed between the third and fourth injections. After limited reimbursed ranibizumab injections, 43.8% patients received other treatments. The safety findings are consistent with previous studies. CONCLUSION: Ranibizumab 0.5 mg treatment for 12 months under real-world settings improved visual outcomes in Taiwanese patients with nAMD.

PLGA nanoparticles containing Lingzhi extracts rescue corneal epithelial cells from oxidative damage.

Oxidative stress-related ocular surface epithelial damage can be initiated by ambient oxygen, UV radiation, and chemical burns. The oxidative damage to cornea can lead to inflammation and even vision loss. Lingzhi (Ganoderma lucidum) is a Chinese herbal drug and has been shown to prevent chronic diseases in clinical practices and has been proven to possess anti-oxidative and anti-inflammatory properties. In the study, we prepared poly (lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) as a sustained drug release system of Lingzhi (LZH) to improve bioavailability. The particle size of developed NPs containing LZH (LZH-NPs) was ~184 nm with narrow size distribution. The results of cellular uptake revealed that using NPs as a drug delivery system could significantly increases the intracellular retention time. The results of the cell viability and chemiluminescence assay revealed that 5 µg/ml of LZH-NPs might be the threshold concentration for cultivation of corneal epithelial cells. After treating LZH-NPs in oxidative damaged cells, the results showed that the inflammation-related gene expression and DNA fragmentation level were both significantly decreased. Post-treatment of LZH-NPs in damaged corneal epithelial cells could increase the cell survival rate. In the rabbit corneal alkali burn model, topical instillation of LZH-NPs could promote corneal wound healing and decrease the inflammation. These results suggest that LZH-NPs may have the potential to treat ocular surface diseases caused by oxidative stress.

Proteomic analysis of Exosomes derived from the Aqueous Humor of Myopia Patients.

Objectives: Myopia is the most common refractive vision disorder. In recent years, several studies have suggested that the alteration of the exosomal protein levels in the aqueous humor (AH) is associated with the development of several eye diseases. Therefore, we aimed to explore the exosomal protein profile of the AH from myopia patients. Methods: Exosomes were isolated from the AH. The quality, concentration, and size distribution of exosomes for each patient were measured using nanoparticle tracking analysis system. Then, the exosomal proteins were purified and digested by trypsin for liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis. Results: There was no significant difference observed between the myopia and control when comparing the concentration and size distribution of exosomes in the AH for each sample. Based on LC-MS/MS analysis, myopia patients had higher and more complex exosomal peptide content. We found two proteins that were common in AH exosomes and eight proteins that were highly expressed in the myopia group. Conclusions: Our results provide pioneering findings for the exploration of the exosomal protein profile in myopia development. Further studies may provide significant information for the diagnosis, clinical treatment, and prognosis of myopia.

Management of neovascular age-related macular degeneration: Taiwan expert consensus.

Neovascular age-related macular degeneration (nAMD) is a leading cause of irreversible vision loss. The present consensus provides suggestions on diagnosis, evaluation, treatment, and follow-up strategies for nAMD from a panel of 11 practicing ophthalmologists. The experts suggest that the baseline visit for nAMD management should include a comprehensive ophthalmologic examination via a multimodal approach consisting of visual and anatomical evaluation. Patients diagnosed with nAMD should be subjected to treatment with the goal of maintaining visual function while diminishing anatomical disease activity and minimizing treatment burden. Currently, anti-VEGF therapy is the main treatment strategy for nAMD, and evaluation involving comprehensive ophthalmologic examination within 1 month of completion of the loading phase comprising three monthly injections is recommended to guide subsequent management. Either a treat-and-extend or pro re nata regimen can be considered for the maintenance phase of anti-VEGF therapy, and the regimen should be chosen and adjusted according to disease activity, reimbursement criteria, financial burden, and patient preferences. In the event of inactive nAMD or poor treatment outcomes, after thorough evaluation and patient education, anti-VEGF therapy may be stopped. The consensus provides practical nAMD management guidelines for ophthalmologists and fellow healthcare professionals.

A Nationwide Study of Myopia in Taiwanese School Children: Family, Activity, and School-Related Factors.

The purpose of the study was to explore how fixed and modifiable family, activity, and school factors affect a student's myopia risk and severity. We used national cross-sectional data from Taiwanese children in Grades 4-6. Bivariate and multivariate analyses, including logistic and ordinary least squares regression, examined factors related to children's myopia status and severity. Age, parent myopia, and school district were associated with risk of myopia. One hour or more per day of near work (OR = 1.26) increased the odds of myopia. The same amount of time in outdoor activities (OR = 0.85) or moderate or vigorous physical activities (OR = 0.82) was associated with lower risk. Near work (ß = 0.06), outdoor activity (ß = -0.04), and outdoor recess (ß = -0.03) predicted myopia severity. To promote healthy vision, nurses should advocate for and implement interventions that increase school children's time outdoors and in physical activities and reduce their time on near work.

A 12-month, prospective, observational study of ranibizumab in treatment-naïve Taiwanese patients with neovascular age-related macular degeneration: the RACER study.

BACKGROUND: The current National Health Insurance scheme in Taiwan reimburses 3 initial plus 4 additional injections of ranibizumab 0.5 mg for eligible patients with neovascular age-related macular degeneration (nAMD). The Ranibizumab AMD Clinical Efficacy in Real-world practice (RACER) study aimed to observe the effectiveness of ranibizumab injections under this reimbursement system. METHODS: RACER was a 12-month, prospective, observational study conducted in treatment-naïve, adult Taiwanese patients with nAMD. Patients received intravitreal ranibizumab 0.5 mg injections in adherence with local prescribing information. RESULTS: Of 161 patients enrolled, 114 (70.8%) completed the 12-month study. Overall, patients received a mean (standard deviation [SD]) of 4.3 (1.7) ranibizumab injections. The mean (SD, [95% confidence interval], P value) gain in best-corrected visual acuity (BCVA) from baseline at Month 3 was 5.2 (12.2, [3.1, 7.3] letters, P < 0.0001) and at Month 12 was 3.4 (15.4, [0.2-6.6] letters, P = 0.0352). Mean central retinal thickness also decreased from baseline at Months 3 and 12 (both P < 0.001). In subgroup analyses, better treatment outcomes at Months 3 and 12 were observed among patients who received a loading dose and those who had a shorter duration of nAMD at baseline. Adverse events were reported in 58.4% of patients; most (94.4%) were mild-to-moderate in severity and 98.8% were deemed unrelated to study treatment. CONCLUSIONS: Treatment with ranibizumab 0.5 mg resulted in significant improvements in visual outcomes among treatment-naïve Taiwanese patients with nAMD. Early treatment and frequent dosing in the real-world setting may be the key to achieving better outcomes.

The presence and impact of herpes virus DNA in recipient cornea and aqueous humor on graft survival following penetrating keratoplasty.

BACKGROUND/PURPOSE: Reactivation of herpes viruses poses threat to corneal graft survival. This study evaluated the presence of herpes simplex virus type 1 (HSV-1), HSV type 2 (HSV-2), and cytomegalovirus (CMV) DNA in recipient corneas and the aqueous humor of patients undergoing penetrating keratoplasty (PKP), and the impact on graft survival. METHODS: This retrospective study reviewed 90 eyes of 71 patients underwent PKP between 2008 and 2016. Cornea and aqueous humor samples were sent for polymerase chain reaction (PCR) testing for viral DNA. The main outcomes were PCR results and graft survival. RESULTS: Recipient corneas tested positive for HSV-1 in 47 eyes (52.2%), for HSV-2 in 24 eyes (26.7%), and for CMV in seven eyes (7.8%). Aqueous humor tested positive for HSV-1 in 44 eyes (48.9%), for HSV-2 in 25 eyes (27.8%), and for CMV in eight eyes (8.9%). The presence of aqueous HSV-1 DNA was associated with higher risk of graft failure (p = 0.005), whereas corneal HSV-1 DNA was not. The presence of HSV-2 DNA had no significant impact on graft survival. Aqueous CMV DNA was associated with higher risk of graft failure in univariate model, but not in multivariate model. CONCLUSION: There were high positive rates of HSV-1, HSV-2, and CMV DNA in recipient corneas and aqueous humor at the time of PKP, even among patients not suspected of latent viral infection. The presence of aqueous HSV-1 DNA was associated with higher risk of graft failure.

Expression Profiling of Exosomal miRNAs Derived from the Aqueous Humor of Myopia Patients.

Myopia is the most common refractive disorder in Eastern Asia. The development of myopia is associated with the cooperation of various ocular tissues. Exosomes in the aqueous humor (AH) have been implicated to modulate intracellular communications by transferring exosomal miRNAs and proteins between cells. These exosomal miRNAs and proteins are likely involved in the pathogenesis of various eye diseases. In this study, we aimed to explore human exosomal miRNA profiles and their roles in myopia development. AH samples were collected from 16 patients (8 myopia and 8 control) undergoing routine cataract surgeries. Exosomes were isolated from AH of each individual using the ExoQuick solution. The numbers and sizes of exosomes were not significantly different between the myopia and control groups. The individual exosomes of the same group were pooled to purify RNA. Unexpectedly, the myopia group contained 2.78-fold total RNA amount than that in the control group. Thereafter, miRNA profiles were analyzed using the OpenArray system. We thus found 15 myopia-specific miRNAs and four myopia-absent miRNAs. By using bioinformatics analysis, we identified six well-known myopia-associated genes that are potential targets of five myopia-specific miRNAs (has-miR-582-3p, has-miR-17-5p, has-miR-885-3p, has-miR-19b-3p, and has-miR-450b-5p). These genes are cholinergic receptor muscarinic 2 (CHRM2), cyclic nucleotide-gated channel beta 3 (CNGB3), vascular endothelial growth factor A (VEGFA), adenosine A2a receptor (ADORA2A), insulin-like growth factor 1 (IGF1), and lumican (LUM). Moreover, CHRM2 may be a target of myopia-absent miRNA (has-miR-378a-5p). In conclusion, we show the expression profiles of AH-derived exosomal miRNAs and their potential roles in myopia development.

Association of multimedia teaching with myopia: A national study of school children.

AIM: The aim of this study was to determine whether students' exposure to digitally projected, multimedia teaching material under naturally varying classroom lighting conditions is associated with myopia risk and severity. DESIGN: A population-based, cross-sectional study in 2012 of children in grades 4-6 across 87 schools in Taiwan. METHODS: Students (N = 3,686) reported demographic information, outdoor time, physical activity and near work. Parents provided their myopia status. Student-reported multimedia teaching frequency and classroom lighting levels were confirmed with direct observation. School nurses conducted vision screening and ophthalmologist referral. Myopia status and severity were measured by spherical equivalent refraction; SE ≤-0.5 dioptres was coded as myopic. Binary logistic and tobit regression were used to estimate the contributions of classroom multimedia exposure and lighting to myopia risk and severity controlling for risk factors. RESULTS/FINDINGS: Age, parental myopia and hours of near work increased the odds of myopia and predicted greater severity. Physical activity and outdoor time predicted lower risk and severity. Multimedia exposure in relatively bright classrooms was associated with greater odds of myopia. Classroom lighting levels during multimedia teaching were inversely related to severity; exposure frequency was unrelated. CONCLUSIONS: Multimedia exposure under brighter classroom conditions may contribute to the myopia incidence in schoolchildren. IMPACT: Teaching with digital projection technology is increasingly prevalent. This may increase children's odds of developing myopia, which has far-reaching and lifelong deleterious effects. School nurses should raise awareness of and promote strategies that reduce this risk, including working with children, parents, school personnel and system leaders to adopt eye-healthy behaviours, practices and policies.

Regulatory SNPs Alter the Gene Expression of Diabetic Retinopathy Associated Secretary Factors.

OBJECTIVES: Diabetic retinopathy (DR) is a common microvascular complication in both type I and type II diabetes. Several previous reports indicated the serum centration of some secretary factors were highly associated with DR. Therefore, we hypothesis regulatory SNPs (rSNPs) genotype in secretary factors may alter these gene expression and lead to DR. METHODS: At first, pyrosequencing were applying to screen the SNPs which present allele frequency different in DR and DNR. Then individual genotyping was processed by Taqman assays in Taiwanese DR and DNR patients. To evaluate the effect of SNP allele on transcriptional activity, we measured promoter activity using luciferase reporter constructs. RESULTS: We found the frequencies of the CC, CG, and GG genotype of the rs2010963 polymorphism were 15.09%, 47.14%, and 37.74% in DR and 12.90%, 19.35%, and 67.74% in DNR, respectively (p = 0.0205). The prevalence of DR was higher (p = 0.00793) in patients with the CC or CG genotype (62.26% and 32.26% for DR and DNR, respectively) compared with the patients with the GG genotype. To evaluate the effect of rs2010963-C allele on transcriptional activity, we measured promoter activity using luciferase reporter constructs. The rs2010963-C reporter showed 1.6 to 2-fold higher luciferase activity than rs2010963-G in 3 cell lines. CONCLUSION: Our data proposed rs2010963-C altered the expression level of VEGFA in different tissues. We suggested small increase but long term exposure to VEGFA may lead to DR finally.

Socioeconomic disparities in preventable hospitalization among adults with diabetes in Taiwan: a multilevel modelling approach.

INTRODUCTION: Literature shows socioeconomic disparities are related to various aspects of diabetes care. However, few studies have explored the relationship between socioeconomics and healthcare outcomes, particularly with regard to preventable hospitalization. This cohort study employed hierarchical modelling to evaluate the role of socioeconomics at both the individual and regional levels in order to examine disparities associated with the preventable hospitalization of diabetes patients in Taiwan. METHODS: This study employed the Longitudinal Health Insurance Database 2010, which provided a representative cohort comprising one million people enrolled in Taiwan's National Health Insurance in 2010. All diabetes patients aged 18 and older who received regular care in 2010 were included in this study. The outcome examined in this study was diabetes-related preventable hospitalization during the period of 2010 to 2011. Socioeconomic status at the individual level was measured according to income and at the regional level according to level of urbanization and the proportion of residents who had completed college education. Control variables included age, gender, comorbidities, time of diabetes diagnosis, participated in the pay-for-performance program status, and the characteristics of regular sources of care, including the level of the facility (i.e., medical centre, regional hospital, local hospital, outpatient clinic) and ownership. Statistical analysis was performed using generalized linear mixed models. RESULTS: A total of 57,791 patients from 25 regions diagnosed with type-2 diabetes mellitus were identified in the National Health Insurance claim data for the year 2010. 1040 of these patients (1.8%) had at least one diabetes-related preventable hospitalization event during the period of 2010-2011. After controlling for the characteristics of patients and health care providers, our results show that dependents and patients in low and middle income brackets (OR = 2.48, 2.44, and 2.08 respectively) as well as those living in regions with a low, median, or high education bracket (OR = 1.32, 1.38, and 1.46 respectively) face a higher probability of preventable hospitalization. CONCLUSIONS: Our results demonstrate that the socioeconomic effects of higher education at the regional level as well as income at the individual level are important factors which affect disparities in diabetes-related preventable hospitalization.

Herpetic keratouveitis mixed with bilateral Pseudomonas corneal ulcers in vitamin A deficiency.

A 56-year-old woman complained of blurred vision and pain in her right eye for several days. Slit lamp examination revealed a large epithelial defect and disciform stromal edema with ring infiltration in her right cornea. Unfortunately, hypopyon and purulent discharge subsequently developed in both eyes. Herpetic keratouveitis and a superimposed pseudomonas infection were diagnosed. A systemic review on the patient showed malnutrition due to her dietary preference and vegetarianism. After the infection was controlled, bilateral epithelial defects persisted for a long time. We performed amniotic membrane transplantation on both eyes and the clinical status improved with administration of vitamin and protein supplements. Although rare in Taiwan, vitamin A deficiency should be kept in mind when conjunctival and corneal xerosis occurred. Vitamin A supplements are suggested because of the increased susceptibility to infection in patients with this clinical status.

Differences in End-of-Life Care Between Patients Who Died of Cancer Diseases and Those Who Died of Noncancer Diseases.

Background and Purpose: Patients with advanced noncancer diseases or advanced cancer diseases may experience similar symptom burdens during the end of their lives. This study aimed to evaluate the differences in receiving hospice care service and in receiving aggressive end-of-life care between patients who died of cancer diseases and those who died of noncancer diseases. Methods: This cross-sectional population-based study used data from the Taiwan National Health Insurance Research Database. Subjects who died of cancers or noncancer diseases from 2010 through 2019 were analyzed to identify the information on patient's characteristics, receipt of hospice care service, receipt of cardiopulmonary resuscitation (CPR) during the last hospitalization, and receipt of airway support interventions during the last hospitalization. The independent effects of various characteristics on the receipt of hospice care, CPR during the last hospitalization, and airway support interventions during the last hospitalization were evaluated using multivariate logistic regressions. Results: A total of 587,490 patients were included, of which 434,142 died of cancers and 153,348 died of noncancer diseases. There were significant trends of increase in receiving hospice care service and significant trends of decrease in receiving CPR or airway support interventions during the last hospitalization in both patients who died of cancers and those who died of noncancer diseases. Compared with patients who died of cancers, those who died of noncancer diseases were less likely to receive hospice care service (adjusted odds ratio [AOR]: 0.087; 95% confidence interval [CI]: 0.085-0.089) and had a higher risk of receiving CPR (AOR: 3.610; 95% CI: 3.521-3.704) or airway support interventions during the last hospitalization (AOR: 3.086; 95% CI: 3.021-3.165). Conclusions: Hospice care service should be promoted for all patients with end-stage diseases especially those with noncancer diseases.
