Abstract
BACKGROUND The kidney and eyes share common pathways and are thought to be closely connected. Chronic kidney disease and major eye diseases, such as cataract and glaucoma, are strongly associated with age. However, further investigation is needed to understand the joint impact of age and kidney diseases on eye diseases. In this study, we assessed the risk of eye diseases in relation to age and kidney failure in Taiwanese adults. METHODS Our study included 127,561 cancer-free volunteers aged 30 to 70 years who participated in the Taiwan Biobank (TWB) project from 2008 to 2020. Information on the main exposures (kidney failure and age) and the outcome (eye diseases, including glaucoma, cataract, xerophthalmia, and retinal detachment) was collected through questionnaires. RESULTS In general, kidney failure and older age were independently associated with a higher risk of eye, particularly cataract and retinal detachment: prevalence odds ratio (POR); 95% confidence interval (CI) = 2.480; 1.635-3.761 for cataract and 3.885; 1.968-7.666 for retinal detachment. A significant interaction between kidney failure and age on cataract was observed (p-value = 0.0002). Age-stratified analysis revealed a higher risk of cataract among patients with kidney failure aged below 50 (POR = 6.534; 95% CI = 2.493-17.124) and between 50 and 60 years (POR = 3.957; 95%CI = 1.986-7.881). Combining kidney failure and age (reference: no kidney failure and age < 50 years), kidney failure in all age groups was associated with a higher risk of cataract. The PORs; 95% CIs were 10.725; 4.227-27.211 for patients below 50 years, 28.487; 14.270-56.866 for those aged 50-60 years, and 43.183; 24.434-72.824 for those > 60 years. Combining cataract and age (reference: no cataract and age < 50 years), patients below 50 years had the highest risk of kidney failure (POR; 95% CI = 9.510; 3.722-24.297). CONCLUSIONS Our study suggests that age and kidney failure may jointly contribute to eye diseases, particularly cataract. The association between cataract and kidney failure could be bidirectional, especially in individuals below 50 years. This significant bidirectional relationship underscores the need for screening patients with cataract for kidney failure and vice versa, particularly in younger adults.

Abstract
Background and Objectives: Cultural beliefs influence the conceptualization, adaptation, and coping strategies for diseases. This study aimed to investigate the impact of cultural beliefs and customs on the willingness to undergo cataract surgery in Taiwan. Materials and Methods: The data were retrospectively retrieved from the national Longitudinal Health Insurance Database 2000 (LHID2000). From the national database, we enrolled patients that were diagnosed with cataracts and underwent cataract surgery from 2001 to 2010. All the patients were stratified according to their gender and living area. Gender was categorized as male or female, and the living area was classified as urban or rural. We compared the difference in the number of surgeries between stratified patient groups in each Chinese lunar month. Results: The number of cataract surgeries decreased significantly in the seventh and twelfth lunar months for both genders. There was a significant reduction in cataract surgeries in both the urban and rural groups during the seventh lunar month. Interestingly, only the seventh lunar month had an association with sex in different living areas, which meant that in the seventh month, there was a gender-specific difference in the surgical numbers. Conclusions: The Taiwanese population holds a belief that surgical procedures, including cataract surgery, during the lunar ghost month is inauspicious. Citizens tend to avoid elective surgery due to cultural practice, resulting in a decrease in surgical numbers during the period of the Chinese New Year. The authorities should consider these cultural behaviors when developing medical policies and allocating resources. Healthcare providers should be aware of these superstitions and take them into account when providing medical care and advice to patients.

Abstract
Background Type 2 diabetes mellitus (T2DM) is caused by a combination of environmental, genetic, and epigenetic factors including, fasting blood glucose (FBG), genetic variant rs841853, and cg19693031 methylation. We evaluated the interaction between rs841853 and cg19693031 on the FBG levels of non-diabetic Taiwanese adults. Methods We used Taiwan Biobank (TWB) data collected between 2008 and 2016. The TWB data source contains information on basic demographics, personal lifestyles, medical history, methylation, and genotype. The study participants included 1300 people with DNA methylation data. The association of cg19693031 methylation (stratified into quartiles) with rs841853 and FBG was determined using multiple linear regression analysis. The beta-coefficients (β) and p-values were estimated. Results The mean ± standard deviation (SD) of FBG in rs841853-CC individuals (92.07 ± 7.78) did not differ significantly from that in the CA + AA individuals (91.62 ± 7.14). However, the cg19693031 methylation levels were significantly different in the two groups (0.7716 ± 0.05 in CC individuals and 0.7631 ± 0.05 in CA + AA individuals (p = 0.002). The cg19693031 methylation levels according to quartiles were β < 0.738592 (< Q1), 0.738592 ≤ 0.769992 (Q1–Q2), 0.769992 ≤ 0.800918 (Q2–Q3), and β ≥ 0.800918 (≥ Q3). FBG increased with decreasing cg19693031 methylation levels in a dose–response manner (ptrend = 0.005). The β-coefficient was − 0.0236 (p = 0.965) for Q2–Q3, 1.0317 (p = 0.058) for Q1–Q2, and 1.3336 (p = 0.019 for < Q1 compared to the reference quartile (≥ Q3). The genetic variant rs841853 was not significantly associated with FBG. However, its interaction with cg19693031 methylation was significant (p-value = 0.036). Based on stratification by rs841853 genotypes, only the CC group retained the inverse and dose–response association between FBG and cg19693031 methylation. The β (p-value) was 0.8082 (0.255) for Q2–Q3, 1.6930 (0.022) for Q1–Q2, and 2.2190 (0.004) for < Q1 compared to the reference quartile (≥ Q3). The ptrend was 0.002. Conclusion Summarily, methylation at cg19693031 was inversely associated with fasting blood glucose in a dose-dependent manner. The inverse association was more prominent in rs841853-CC individuals, suggesting that rs841853 could modulate the association between cg19693031 methylation and FBG. Our results suggest that genetic variants may be involved in epigenetic mechanisms associated with FBG, a hallmark of diabetes. Therefore, integrating genetic and epigenetic data may provide more insight into the early-onset of diabetes.

Abstract
This is a retrospective study in consecutive cases with cultured-proven endogenous endophthalmitis (EE) treated at the largest tertiary medical center in middle Taiwan in the past 10 years. 83 eyes of 70 patients were enrolled. The mean interval between systemic diseases to the diagnosis of EE was 8.84 ± 6.94 days. The mean initial visual acuity (VA) in the logarithm of minimal angle of resolution (logMAR) was 1.63 ± 0.87. Type 2 diabetes mellitus was the most common predisposing medical illness (N = 53, 63.86%). The most common infectious sources were intra-abdominal abscess (N = 36, 43.37%), and the second most reason was urinary tract infection. The causative pathogen was Gram-negative predominant (N = 64, 77.11%). After aggressive treatment, 34.94% of eyes regain useful vision, and only six eyes underwent enucleation or evisceration. The binary multivariate logistic regression model revealed that female gender (95% CI 1.002–19.036, p = 0.05, OR 4.37), initial VA logMAR (95% CI 0.089–0.550, p = 0.01, OR 0.22), and more intravitreal injections (95% CI 0.368–0.927, p = 0.023, OR 0.58) were independent risk factors influencing final outcomes. Based on the results mentioned above, early diagnosis is recommended to gain better outcomes. The mean interval between systemic diseases to the diagnosis of EE was 8.84 ± 6.94 days in our sample population, clinicians should maintain a higher index of suspicion during this period when encountering patients with bacteremia or fungemia.

Abstract
Various sociocultural factors affect healthcare-seeking behaviors. In Taiwanese society, superstitions and lunar festivals play important roles in people’s lives. We investigated the impact of “Ghost Month” (the 7th lunar month) and Chinese New Year (the 12th lunar month and the 1st lunar month of the following year) on the number of elective surgeries and emergent surgeries in Taiwan. The number of total knee replacement (TKR) surgeries and proximal femur fracture (PFF) surgeries in each lunar month from 2000 to 2011 were extracted from the Taiwan National Health Insurance Database, a computerized and population-based database. Patients were then sorted by location of residence or gender. The average number of TKR surgeries performed was significantly lower during the 1st, 7th, and 12th lunar months in urban areas, whereas in rural areas this trend was only evident in the 7th and 12th lunar months. There was however, no significant difference in the average number of PFF surgeries in each lunar month except for an increase seen in the 1st lunar month in rural patients (p<0.05). When sorted by gender, the average number of TKR surgeries was significantly decreased in the 7th and 12th lunar months in male patients, and decreased in the 1st, 7th, and 12th lunar months in female patients. In contrast, there was no difference in the average numbers of PFF surgeries in the 7th and 12th lunar months either in male or female patients. We proposed that the timing of elective surgeries such as TKR might be influenced by Ghost Month and Chinese New Year; however, emergent PFF surgeries were not significantly influenced by sociocultural beliefs and taboos in Taiwan.

Abstract
BACKGROUND In randomized, controlled trials of open-angle glaucoma (OAG) or ocular hypertension (OHT), bimatoprost 0.01 % improved tolerability while retaining the intraocular pressure (IOP)-lowering efficacy of bimatoprost 0.03 %. Given geographic/racial differences in glaucoma presentation, the APPEAL study assessed the occurrence and severity of hyperemia produced by bimatoprost 0.01 %, and its efficacy, in the Taiwanese clinical setting. METHODS In this multicenter, open-label, observational study, treatment-naïve and previously treated patients with OHT or OAG received once-daily bimatoprost 0.01 % for 12 weeks. Hyperemia (primary endpoint) was graded at baseline, week 6, and week 12 using a photonumeric scale (0, +0.5, +1, +2, +3), grouped (≤ +1, none to mild; ≥ +2, moderate to severe), and reported as unchanged from baseline, improved, or worsened. IOP assessments followed the same schedule. Supplemental efficacy analyses were conducted based on previous therapies. RESULTS The intent-to-treat population (N = 312) included treatment-naïve (13.5 %) and previously treated (86.5 %) patients; mean age was 53.3 years. At baseline, 46.3 % of previously treated patients were receiving prostaglandin analog (PGA) monotherapy. At week 12, 91.2 %, 5.9 %, and 2.9 % of treatment-naïve patients exhibited unchanged, worsened, and improved hyperemia from baseline, respectively; 77.9 %, 12.9 %, and 9.2 % of previously treated patients showed no change, worsening, and improvement, respectively. There were no statistically significant shifts in hyperemia severity in either group, or in subgroups based on previous use of any PGA, any non-PGA, latanoprost, or travoprost monotherapies. In treatment-naïve patients, mean IOP reduction from baseline (18.0 ± 3.8 mm Hg) was 3.6 mm Hg at week 12 (P < 0.0001); 83.3 % had baseline IOP ≤ 21 mm Hg. In previously treated patients, mean additional IOP reduction from baseline (17.8 ± 3.9 mm Hg) was 2.6 mm Hg (P < 0.0001); similar results were observed in patient subgroups based on previous therapies. CONCLUSIONS In the Taiwanese clinical setting, bimatoprost 0.01 % provided significant IOP lowering in treatment-naïve patients (regardless of baseline IOP) and previously treated patients (even those with relatively low IOP on other therapies), while causing no significant changes in hyperemia from baseline.

Abstract
Background In Taiwan, there is a good universal healthcare system to the patients; however, the majority of Taiwanese seek the complementary and alternative medicine when they are injured or ill. The traditional Chinese medicine, which is a branch of complementary alternative medicine, is prevalent in Taiwan. Without proper sequence of maneuvers, either traditional Chinese medicine or conventional medicine might cause unexpected complications. We report a case of 76-year-old woman who was manipulated by a bonesetter, leading to bilateral anterior shoulder dislocations. To the authors’ best knowledge, this injury mechanism of bilateral shoulder dislocations has not been reported in the literature. Since the traditional Chinese medicine is popular in Taiwan, proper training with better skills for the practitioners should be emphasized. We highlight the integration and collaboration of traditional Chinese medicine with western medicine to achieve a better health care for the patients. Case presentation A 76-year-old Taiwanese woman has been suffering from soreness and stiffness of bilateral shoulders for 6 months. She went to a bonesetter for mobilization for her shoulders. After manipulations for bilateral shoulders, the woman experienced locked both shoulders with sharp pain. She came to our institute, where the radiographs confirmed bilateral anterior shoulder dislocations. Closed reduction for the dislocations was done by the physician. The patient returned to good range of motion of bilateral shoulders after subsequent rehabilitation without any neurologic deficits. Conclusions To the authors’ best knowledge, this unusual injury of bilateral anterior shoulder dislocations had not been reported. The possible mechanism of this injury and the health belief of traditional Chinese medicine in Taiwan are discussed. Improper shoulder manipulations would lead to unexpected complication in any medical practices. We suggest that both traditional Chinese medicine and conventional medicine should follow specific sequences of manipulations; Collaboration and integration with each other could achieve a better healthcare for the patients.

METHODS A 38-year-old woman presented with acute visual loss in her right eye. Funduscopy showed a cilioretinal artery occlusion, which was confirmed by a fluorescein angiography. An embolus was found in the distal segment of the vessel. RESULTS Color Doppler images of right internal carotid artery (ICA) disclosed a pseudolumen, suggesting a diagnosis of carotid dissection. Retrobulbar color Doppler image showed relative low flow velocity in the ophthalmic artery without flow reversal. Magnetic resonance angiography and cerebral angiogram showed total occlusion of the right ICA. Follow-up visual field examination revealed an inferior central defect fed by the cilioretinal artery. CONCLUSION The pathogenesis of retinal artery occlusion caused by carotid dissection may be embolic or hemodynamic. In our case, a permanent visual defect was related to embolic occlusion of the cilioretinal artery.

Abstract
Herein, we present a complete three-dimensional (3D) map of major neuropil structures in the central brain of the cockroach Diploptera punctata. The positions of the structures have been ascertained by confocal microscopy, which, until now-for reasons of tissue opacity and nonhomogeneity-has been thought impractical in imaging fluorescently labeled structures thicker than 150 microm. In this report, however, we have used digestive enzymes and microwave-aided fixation to stain, clear, and optically section, in its entirety, an intact central brain more than 500 microm thick. The central brain from an adult female cockroach was stained thoroughly with the membrane probe NBD-ceramide and the DNA probe propidium iodide. The central brain as well as such neuropil regions as mushroom bodies, central complex, antennal glomeruli, and lobus glomerulati were individually outlined, segmented, and reconstructed in three dimensions to a spatial resolution of approximately 1 microm in the X-Y plane and 3 microm in the Z plane. The volume and surface area of each neuropil compartment were determined, and Kenyon cells of the mushroom bodies were counted. We determined that each brain hemisphere contains about 230,000 Kenyon cells, 99 antennal lobe glomeruli, and 40 lobus glomerulatus glomeruli. Segmented compartments were assigned as separate channels and merged into a single data base to reconstruct a 3D central brain containing eight different channels. This is the first 3D map at submicron resolution of an entire animal's brain that measures more than 500 microm in thickness.

Abstract
Our previous works demonstrated that ligands of macrophage scavenger receptor (MSR) induce protein kinases (PKs) including protein-tyrosine kinase (PTK) and up-regulate urokinase-type plasminogen activator expression (Hsu, H. Y., Hajjar, D. P., Khan, K. M., and Falcone, D. J. (1998) J. Biol. Chem. 273, 1240--1246). To continue to investigate MSR ligand-mediated signal transductions, we focus on ligands, oxidized low density lipoprotein (OxLDL), and fucoidan induction of the cytokines tumor necrosis factor-alpha (TNF) and interleukin 1 beta (IL-1). In brief, in murine macrophages J774A.1, OxLDL and fucoidan up-regulate TNF production; additionally, fucoidan but not OxLDL induces IL-1 secretion, prointerleukin 1 (proIL-1, precursor of IL-1) protein, and proIL-1 message. Simultaneously, fucoidan stimulates activity of interleukin 1-converting enzyme. We further investigate the molecular mechanism by which ligand binding-induced PK-mediated mitogen-activated protein kinase (MAPK) in regulation of expression of proIL-1 and IL-1. Specifically, fucoidan stimulates activity of p21-activated kinase (PAK) and of the MAPKs extracellular signal-regulated kinase (ERK), c-Jun NH(2)-terminal kinase (JNK), and p38. Combined with PK inhibitors and genetic mutants of Rac1 and JNK in PK activity assays, Western blotting analyses, and IL-1 enzyme-linked immunosorbent assay, the role of individual PKs in the regulation of proIL-1/IL-1 was extensively dissected. Moreover, tyrosine phosphorylation of pp60Src as well as association between pp60Src and Hsp90 play important roles in fucoidan-induced proIL-1 expression. We are the first to establish two fucoidan-mediated signaling pathways: PTK(Src)/Rac1/PAK/JNK and PTK(Src)/Rac1/PAK/p38, but not PTK/phospholipase C-gamma 1/PKC/MEK1/ERK, playing critical roles in proIL-1/IL-1 regulation. Our current results indicate and suggest a model for MSR ligands differentially modulating specific PK signal transduction pathways, which regulate atherogenesis-related inflammatory cytokines TNF and IL-1.

Abstract
One hundred and twenty-seven children aged 3-6 years were allocated to four groups. All of them received venous cannulation on the dorsum of the hand. On induction, the group L1, L2 and L3 patients received propofol 3 mg/kg mixed with lignocaine 0.15 mg/kg, 0.3 mg/kg, 0.6 mg/kg, respectively. The group T patients received thiopentone 3 mg/kg, then propofol 1.5 mg/kg mixed with lignocaine 0.075 mg/kg. Pain on injection was categorized into two-assessment items (facial expression and limbs withdrawal). The facial expression category were subdivided into none, mild (knit of brows), moderate (grimace), and severe (crying). The withdrawal of limbs was categorized into none, mild (withdrawal of hand), moderate (withdrawal of fore-arm and arm), severe (withdrawal of arm and twisting of body). Patients were monitored using an electrocardiogram, pulse oximeter, autonomic noninvasive blood pressure measuring device and capnography. The patient characteristics did not differ significantly among the four groups. Pain on injection was significantly more frequent in the group L1 patients (81%) compared with the group T (27%) patients. Increasing lignocaine dose reduced the incidence of pain graded as "moderate" or "severe" though there was no significant difference. The incidences of excitatory effect on propofol injection were reduced with increasing lignocaine dose and prior administration of thiopentone but there were no obviously differences among groups. We concluded that thiopentone reduced injection pain on propofol and should be recommended.

Abstract
The identification of L-739,943 (8b), a potent, orally bioavailable benzolactam growth hormone secretagogue, is obtained from zwitterionic L-692,429 through modification of its amino acid side chain and replacement of the acidic 2'-tetrazole with the neutral and potency enhancing 2'-(N-methylaminocarbonylamino)methyl substituent. L-739,943 is orally active for the release of growth hormone in beagle dogs at doses as low as 0.5 mg/kg. Oral bioavailability in dogs of 8b is 24% at a dose of 2 mg/kg with a mean drug Cmax of 145 +/- 46 ng/mL. L-739,943 represents a significant breakthrough in terms of both potency and oral bioavailability as compared to the prototype benzolactam L-692,429.
