ABSTRACT
Resveratrol, acting as a prebiotic, and propionate, functioning as a postbiotic, hold promise for preventing hypertension in chronic kidney disease (CKD). Previously, we employed propionate to enhance the bioavailability of resveratrol through esterification, resulting in the production of a resveratrol propionate ester (RPE) mixture. In this study, we purified 3-O-propanoylresveratrol (RPE2) and 3,4'-di-O-propanoylresveratrol (RPE4) and investigated their protective effects in a juvenile rat adenine-induced CKD model. To this end, male Sprague Dawley rats aged three weeks (n = 40) were divided into five groups: control; CKD (rats fed adenine); CKRSV (CKD rats treated with 50 mg/L resveratrol); CDRPE2 (CKD rats treated with 25 mg/L RPE2); and CKRPE4 (CKD rats treated with 25 mg/L RPE 4). RPE2 and PRE4 similarly exhibited blood pressure-lowering effects comparable to those of resveratrol, along with increased nitric oxide (NO) availability. Furthermore, RPE2 and RPE4 positively influenced plasma short-chain fatty acid (SCFA) levels and induced distinct alterations in the gut microbial composition of adenine-fed juvenile rats. The supplementation of RPE2 and RPE4, by restoring NO, elevating SCFAs, and modulating the gut microbiota, holds potential for ameliorating CKD-induced hypertension.

BACKGROUND/AIMS: To distinguish the clinical feature of nanophthalmos (NNO) caused by mutations in protease serine 56 (PRSS56), membrane-type frizzled-related protein (MFRP), myelin regulatory factor (MYRF) and transmembrane protein 98 (TMEM98) and to evaluate the association between angle-closure glaucoma (ACG) and NNO. METHODS: Variants in those four genes were identified through exome sequencing/whole genome sequencing data, and bioinformatic analysis was conducted to identify pathogenic/likely pathogenic (P/LP) variants. This observational study comprehensively summarised ophthalmological data of 67 patients with NNO from 63 families. Ocular parameters from 68 eyes without surgical treatment were subjected to further analysis. RESULTS: Totally, 67 patients from 63 families harboured 57 P/LP variants in the four genes, including 30 in PRSS56 (47.6%), 23 in MFRP (36.5%), 5 in TMEM98 (7.9%) and 5 in MYRF (7.9%). ACG was present in 79.1% of patients. An analysis of ocular parameters from 68 eyes revealed that shorter axial length (AL), lower vitreous-to-AL ratios and severe foveal hypoplasia were associated with variants in PRSS56 and MFRP. Uveal effusion was more common in patients with PRSS56 variants, while retinitis pigmentosa was frequently observed in patients with MFRP variants. Patients with MYRF variants exhibited the thinnest retinal nerve fibre layer thickness. Patients with TMEM98 variants had an earlier average onset age of glaucoma. CONCLUSION: Variants in PRSS56 and MFRP are the most common genetic cause of NNO. ACG is a severe complication frequently observed in these patients. Earlier onset of ACG is observed in patients with dominant NNO, while foveal hypoplasia is more common in patients with recessive disease. Recognising these features is helpful in clinical care and genetic counselling.
ABSTRACT
BACKGROUND: Pneumococcal Polysaccharide Vaccine (PPV-23), designed to protect against the most common serotype of Streptococcus pneumoniae, is intended to protect the elderly and other high-risk groups. However, the immunogenicity of all 23 pneumococcal polysaccharide vaccines in older adults has not been thoroughly studied. OBJECTIVE: The purpose of this study is to look into the factors that influence the effect of the pneumonia vaccine on the elderly over 60 years old in Shenzhen, as well as their IgG antibody level against Streptococcus pneumoniae. METHODS: To determine the immune effectiveness of pneumococcal vaccination in older adults over 60 years old, we used the 3rd generation enzyme-linked immunosorbent assay to detect the antibody level of older adults to all 23 pneumococcal polysaccharide vaccines following pneumococcal immunization. RESULTS: Vaccination, the number of physical examinations, pneumonia knowledge, and the pneumonia vaccination policy of the elderly in Shenzhen were all positively correlated with Streptococcus pneumoniae antibody positivity. The distribution of subtypes did not differ between elderly adults (over 65) and younger adults (under 65). The GMCs of IgG antibodies to PPS were significantly lower in males than in females for types 7f, 18c and 19a. At the same time, we found that people with chronic respiratory disease have lower type 9n than people without chronic respiratory disease. Other chronic diseases, such as hypertension and diabetes, had no difference in subtype distribution. CONCLUSION: There was a statistically significant difference in antibody positivity rates for older people with more frequent medical check-ups in Shenzhen, indicating that publicity is playing a role. The effects of age, gender, and chronic diseases on naturally acquired anti-PPS IgG differ.

INTRODUCTION: This study investigated the clinical characteristics of and risk factors for microcystic macular edema (MME) in patients with chronic primary angle-closure glaucoma (CPACG) and primary open-angle glaucoma (POAG). METHODS: This retrospective observational study included 1,588 eyes from 926 glaucoma inpatients and analyzed the patients' basic demographic information, visual field parameters, macular scans, and peripapillary retinal nerve fiber layer thickness. RESULTS: Our findings were that the incidence rate of MME was 3.97% (34/857) in CPACG and 5.88% (43/731) in POAG. MME was predominantly diagnosed at an advanced stage in CPACG (almost 100%) compared to POAG (93.02%). MME was most frequently involved in the inferior (83.12%) quadrant of the peri-macular region in both CPACG and POAG. Risk factors for MME occurrence in CPACG and POAG included lower visual field mean deviation (OR = 1.14, 95%: CI 1.05-1.24, p = 0.003; OR = 1.14, 95% CI: 1.06-1.21, p < 0.001) and younger age (OR = 0.92, 95% CI: 0.88-0.96, p < 0.001; OR = 0.96, 95% CI: 0.93-0.99, p = 0.003), while female sex (OR = 0.30, 95% CI: 0.11-0.84, p = 0.022) reduced the MME occurrence in POAG. CONCLUSION: MME could develop in both CPACG and POAG patients, occurring earlier in POAG. The inferior peri-macular region is commonly affected. Younger age and poorer visual field are risk factors for MME in glaucoma patients.

Purpose: To report the prevalence, clinical characteristics and risk factors for paracentral acute middle maculopathy (PAMM) following acute primary angle closure (APAC) and acute primary angle closure glaucoma (APACG). Methods: This retrospective study consecutively recruited patients diagnosed with APAC or APACG. Based on the spectral domain optical coherence tomography characteristics, PAMM eyes were divided into three stages. Characteristics of different stages such as the time from symptoms to treatment (TST), retinal thickness and BCVA improvement were analyzed. The risk factors of PAMM were evaluated by binary logistic regression models. Results: A total of 781 eyes of 781 APAC or APACG patients were included, and PAMM was found in 22 (2.9%) of them. Stage III eyes had a significantly longer TST than stage I eyes (P = 0.008) while exhibiting significantly thinner retinal thicknesses (P < 0.0001). The BCVA improvement was significantly worse in the eyes treated in stage III than in those treated in stage I (P = 0.008). Older age, longer axial length and without type 2 diabetes were associated with a lower risk of incident PAMM (OR = 0.95, P = 0.028; OR = 0.52, P = 0.019; OR = 3.92, P = 0.022). Conclusion: PAMM can be secondary to APAC or APACG at a rate of 2.9%. Different visual outcomes were observed in patients who received the intervention at different stages of PAMM. Younger patients with a shorter axial length and type 2 diabetes were found to be more susceptible to PAMM.
ABSTRACT
PRCIS: The current study highlights distinct choroidal alterations in primary open angle (POAG) and primary angle closure (PACG) glaucomas, underscoring the potential of the Choroidal Vascularity Index (CVI) as a valuable indicator for understanding glaucoma pathogenesis. PURPOSE: To evaluate choroidal structural changes in patients with POAG and PACG and healthy controls utilizing the CVI and subfoveal choroidal thickness by enhanced depth imaging optical coherence tomography. METHODS: This study was cross-sectional. A total of 171 eyes of 171 subjects, comprising 69 eyes with untreated POAG, 58 eyes with untreated PACG, and 44 healthy eyes, were enrolled in this study. Subfoveal choroidal thickness, luminal area (LA), stromal area (SA), and total choroidal area were measured on enhanced depth imaging-optical coherence tomography scans. The CVI parameter is calculated as the proportion of LA to the total choroidal area. RESULTS: This study included 69 patients with POAG with a mean age of 51.4 ± 13.3 years, 58 patients with PACG with a mean age of 57.0 ± 7.3 years, and 44 healthy subjects with a mean age of 51.11 ± 10.7 years. The CVI in the POAG and PACG groups was significantly lower than that in the control group ( P = 0.001 and P = 0.005, respectively); however, not significantly different between the two glaucoma groups ( P = 1.000). POAG eyes had significantly lower LA than PACG and controls ( P = 0.014 and P = 0.049, respectively), whereas PACG eyes had significantly greater SA than controls ( P = 0.041). CONCLUSIONS: The CVI of POAG and PACG eyes was significantly lower than that of normal eyes. A reduced LA was observed mainly in eyes with POAG, and an increased SA was observed mainly in eyes with PACG. The role of the choroid may differ between POAG and PACG eyes.

PURPOSE: To evaluate the outcomes of microcatheter-assisted trabeculotomy (MAT) in childhood glaucoma (primary congenital glaucoma [PCG], juvenile open-angle glaucoma [JOAG], and secondary childhood glaucoma [SCG]) after failed glaucoma surgery. DESIGN: Retrospective interventional case series. METHODS: Patients with childhood glaucoma who underwent MAT after failed glaucoma surgery with at least 12 months of follow-up were evaluated. Pre- and postoperative intraocular pressure (IOP) and the number of glaucoma medications were recorded and compared. Success was defined as an IOP ≤21 mm Hg with or without glaucoma medication. Analysis of variance was used to compare the glaucoma subgroups. RESULTS: Forty-five eyes (42 patients) with a median follow-up period of 19 months were included. The median age at the time of MAT was 10 (range, 0.8-33) years. The mean number of previous surgeries was 1.3 ± 0.5. The IOP had significantly reduced from baseline in all PCG, JOAG, and SCG patients (27.9 ± 4.5 vs 16.3 ± 8.0 mm Hg, P = .001; and 30.8 ± 9.4 vs 13.5 ± 3.0 mm Hg, P < .001; and 31.5 ± 7.1 vs 16.5 ± 5.3 mm Hg, P = .001, respectively). Fewer glaucoma medications were needed after MAT in all 3 groups (each P < .001). At the last visit, the total success rates in PCG, JOAG, and SCG were 93.8%, 100%, and 88.9%, respectively. No severe complications were observed. CONCLUSION: MAT can effectively manage PCG, JOAG, and SCG after failed surgeries, providing successful outcomes and no serious complications. Following failed glaucoma surgeries, MAT may offer these patients with childhood glaucoma an excellent opportunity to achieve IOP control.

AIMS: To evaluate the efficacy and safety of anterior segment reconstruction (ASR) in congenital fibrovascular pupillary membrane-induced secondary glaucoma (CFPMSG) basing ultrasound biomicroscopy (UBM) classification. METHODS: This ambispective cohort study enrolled patients with CFPMSG who underwent ASR between January 2014 and September 2020. Comprehensive ophthalmic examinations and UBM were performed before surgery and postoperatively. The patients were classified into three types according to the UBM configurations. Anterior chamber recovery (ACR) was defined as deepening in anterior chamber (≥1.5 mm all through final follow-up (FFU), while success following ASR was defined as ACR and intraocular pressure (IOP)≤21 mm Hg. RESULTS: 25 eyes of 25 patients underwent ASR (average age at operation 5.8±5.0 months, 48% girls) with FFU 15.8±16.9 months. Enrolled subjects were classified into type â (11 eyes), type â ¡ (11 eyes) and type â ¢ (3 eyes). After ASR, 23 eyes (92%) achieved ACR, and the mean ACD increased in all groups (p=0.006, <0.001 and 0.003, respectively). Eyes with types â and â ¡ demonstrated a reduction of IOP (p=0.009 and 0.002, respectively). ASR success rate was highest in type â (72.9%) compared with types â ¡ and â ¢ (18.2% and 0%, respectively; p=0.011). ASR led to decreased number of antiglaucoma medications for type â CFPMSG at FFU (p=0.016). No vision-threatening postoperative complications occurred. CONCLUSIONS: ASR for CFPMSG results in increased ACD and improvement in IOP. Postoperative IOP control was best in type â CFPMSG but not as effective in types â ¡ and â ¢. UBM-based classification helps to predict the surgical outcome of ASR in CFPMSG.
ABSTRACT
(1) Background: To evaluate the efficacy and safety of combined surgery (limited pars plana vitrectomy, anterior-chamber stabilized phacoemulsification, IOL implantation and posterior capsulotomy, LPPV + ACSP + IOL + PC) in complex nanophthalmos. (2) Methods: Patients with complex nanophthalmos were recruited to undergo LPPV + ACSP + IOL + PC from January 2017 to February 2021. Preoperative and post-operative intraocular pressure (IOP), best corrected visual acuity (BCVA), anterior chamber depth (ACD), and number of glaucoma medications were compared using the paired t-test or Wilcoxon signed rank sum tests. Surgical success rate was evaluated. Surgery-associated complications were documented. (3) Results: Forty-five eyes of 37 patients with complex nanophthalmos were enrolled. The mean follow-up period was 21.7 ± 10.6 months after surgery. Mean IOP decreased from 32.7 ± 8.7 mmHg before surgery to 16.9 ± 4.5 mmHg (p < 0.001) at the final follow-up visit, mean logMAR BCVA improved from 1.28 ± 0.64 to 0.96 ± 0.44 (p < 0.001), mean ACD significantly increased from 1.14 ± 0.51 mm to 3.07 ± 0.66 mm (p < 0.001), and the median number of glaucoma medications dropped from 3 (1, 4) to 2 (0, 4) (p < 0.001). The success rate was 88.9% (40 eyes) at the final follow-up visit. Two eyes had localized choroidal detachments which resolved with medical treatment. (4) Conclusions: LPPV + ACSP + IOL + PC is a safe and effective surgical procedure, which can decrease IOP, improve BCVA, deepen the anterior chamber, and reduce the number of glaucoma medications in patients with complex nanophthalmos. It can be considered as one of the first treatment in nanophthalmic eyes with complex conditions.
ABSTRACT
INTRODUCTION: The aim of this study was to investigate the long-term visual outcomes and factors associated with vision loss in Chinese patients with primary congenital glaucoma (PCG) after successful intraocular pressure (IOP) control (IOP ≤21 mm Hg). METHODS: PCG patients with IOP control who were examined in the glaucoma clinic at Zhongshan Ophthalmic Center from 2019 to 2020 were enrolled. The final visual outcome was evaluated by the best corrected visual acuity (VA). Univariate and multivariate analyses were used to investigate the associations of visual impairment with potential risk factors. The causes for decreased VA (<20/50) were also analyzed. RESULTS: Fifty-nine patients (95 eyes) were included in the cohort, with a mean age of 8.7 years. The mean logMAR VA was 0.62 ± 0.64. The VAs of eyes treated for PCG were good (≥20/50) in 56%, fair (20/60-20/200) in 30%, and poor (<20/200) in 14%. The most common cause of decreased VA was amblyopia (64.3%). Multivariate logistic regression analysis showed that undergoing multiple surgeries (OR: 4.86, 95% CI: 1.11-21.16, p = 0.035) was significantly associated with visual impairment. CONCLUSION: The results showed that good VA was attainable in approximately half of PCG eyes under IOP control. Prompt and effective treatment of PCG, management of amblyopia and ocular comorbidities may be potential steps toward achieving good visual outcomes in PCG patients.

Purpose: The purpose of this study was to describe and summarize the clinical features of congenital fibrovascular pupillary membrane-induced secondary glaucoma (CFPMSG). Design: Cross-sectional case series. Methods: Eyes of 32 patients with CFPMSG were enrolled. Demographic data, including gender, laterality, age at presentation, and age at onset of glaucoma were collected. Patients underwent comprehensive ophthalmic examinations and ultrasound biomicroscopy (UBM). CFPMSG eyes were classified into three groups based on UBM findings and intergroup analysis was performed using ANOVA. Results: The average age at presentation was 2.4 ± 4.6 months (mean ± SD) and at glaucoma onset was 3.8 ± 4.5 months. Compared to normal fellow eyes, all affected eyes had increased intraocular pressure (IOP), axial length, corneal diameter, and central corneal thickness, and decreased anterior chamber depth (ACD) (all P ≤ 0.001). Twenty-two affected eyes (68.8%) had evidence of glaucomatous optic neuropathy. Based on iris configuration on UBM, eyes were classified as 53% type I ("U" shape), 34% type II ("Y" shape), and 13% type III (no anterior chamber). IOP in types II (33.8 ± 5.9 mmHg) and III (35.2 ± 5.9 mmHg) was significantly higher than in type I eyes (26.5 ± 5.1 mmHg). The ACD was shallower in type II compared to type I (P = 0.045). Conclusion: Congenital fibrovascular pupillary membrane-induced secondary glaucoma is characterized by ocular hypertension, corneal enlargement and edema, axial length elongation, and glaucomatous optic neuropathy. Glaucoma in this condition is secondary to pupillary block and angle-closure. UBM provides important information for the diagnosis and classification of CFPMSG. This novel classification system demonstrated varying levels of severity and may guide on management of this disease.
ABSTRACT
Background: The purpose of this study was to analyze the ocular biometric parameters of primary angle-closure disease (PACD) in younger patients and compare them with those of elderly patients. Methods: This clinic-based, cross-sectional study included 154 eyes of 154 patients with PACD, consisting of 77 eyes of patients aged 40 years or younger and 77 eyes of patients older than 40. The PACD case definition was compatible with the ISGEO definition. Anterior segment parameters were measured by ultrasound biomicroscopy, axial length (AL) and lens thickness (LT) were measured by A-scan ultrasonography measurements, and the thickness of the retina and choroid were measured by optical coherence tomography. The differences in ocular biometric parameters between different age groups were compared by independent sample t-tests or Mann-Whitney U tests, and the correlation between the parameters and age was analyzed. Results: Compared to older PACD patients, the lens vault(LV),LV/LT and subfoveal choroidal thickness (SFCT) of younger patients were larger, while the peripheral and mean iris thickness (IT), trabecular-ciliary angle (TCA), ciliary body thickness (CBT), AL and LT were smaller (all P < 0.01). There was no significant difference in anterior chamber depth, anterior chamber width, pupil diameter, angle opening distance at 500 µm from the scleral spur, anterior chamber angle and iris convexity between the two groups (all P > 0.05). AL, LT, IT, TCA and CBT were positively associated with age (all P < 0.001), while LV and SFCT were negatively associated with age (P = 0.027 and P < 0.001, respectively). Conclusions: Compared with elderly patients, younger PACD patients had more anteriorly positioned lenses, thinner and more anteriorly rotated ciliary bodies, thicker choroids, and shorter axial length. These characteristics might be important anatomical bases for the earlier onset of PACD and the higher risk of malignant glaucoma after filtering surgery.
ABSTRACT
The purpose of this study was to explore the effectiveness of an essential oil massage on the sleep quality of the critical care nurses. A randomized controlled trial with single blind was conducted. A total of 112 critical care nurses were recruited. Participants were randomly allocated to either the experimental or control group. Only the experimental group received four sessions consisting of a lavender essential oil massage. The results of this study revealed that the overall subjective sleep quality and objective sleep parameters did not reach a significant difference between the two groups before and after the intervention, but a progressive the subjective sleep quality score reduction was observed in the experimental group. The findings of this study might provide information to critical care nurses who are under high pressure to find the optional alternative way of managing their self-sleep health by employing safe and convenient alternatives through aromatherapy.

The switchable chimeric antigen receptors (CARs) have shown many advantages in CAR T-cell therapy. However, human primary T-cells are required to evaluate antigen-specific adaptors by IFN-γ assay or FACS analysis, which limits the throughput of adaptor screening. A sensitive and robust CD16-CAR Jurkat NFAT-eGFP reporter system has been developed to assess the therapeutic efficacy of antibody-targeted CAR-T-cell by effectively evaluating the T-cell activation by various tumor cells and the impact of immune checkpoint inhibitor antibodies. This reporter system facilitates the screening of targeted antibodies in a high throughput manner for the development of improved T-cell immunotherapy.

BACKGROUND & PROBLEMS: Poor sleep quality during hospitalization may lead to post-hospital symptoms and increase readmission rates and mortality. Patients in our intensive care unit (ICU) reported low mean scores on the Richards-Campbell Sleep Questionnaire (RCSQ) during their third and fifth days of hospitalization (49.7 mm and 51.7 mm, respectively). Therefore, a project to improve sleep quality in the ICU was established. PURPOSE: To increase the mean RCSQ score from 51.7 mm to 76.0 mm on the fifth day. The fifth day timeframe was chosen because of the disease conditions of the patients and related clinical-medical factors. RESOLUTIONS: The project team proposed an evidence-based, sleep care bundle that included non-medication pain control, environmental regulation, improvement of the care process, and individualized sleep care. RESULTS: After implementing the bundled intervention, the mean RCSQ score of patients in our ICU increased from 49.7 mm to 55.9 mm on the third day and from 51.7 mm to 80.9 mm on the fifth day. CONCLUSIONS: This application of a sleep care bundle effectively improved the factors affecting sleep disturbance and improved quality of sleep in the patients in our intensive care unit.

Primary angle-closure glaucoma (PACG) and retinitis pigmentosa (RP) can co-occur, but the mechanism of their association is not yet established. The purpose of this study was to investigate the differences in ocular biometry parameters and molecular genetics in patients with PACG with or without RP, and to determine the association between PACG and RP. Patients with early-onset PACG (age of onset <45 years) with or without RP were selected from the glaucoma outpatient department after full ocular examinations by the same glaucoma specialist (LX). Ocular biometry parameters were statistically analyzed. Blood samples were collected from the probands, and genomic DNA was sent out for whole exome sequencing. Variants in 326 selected genes, were extracted from the whole exome sequencing data and filtered using multiple bioinformatics analysis. The 326 genes included 10 PACG-associated genes from two genome wide association studies; 45 genes associated with anterior segment dysgenesis, microcornea, and microphthalmia; and 271 RetNet genes. Potential pathogenic variants (PPV) were obtained and underwent further genotype-phenotype analysis. As a result, a total of 32 probands with early-onset PACG were collected; nine had accompanying RP. No significant differences were noted for ocular biometry parameters between patients with PACG with RP and with PACG alone. Systematic analysis of the variants revealed that 16 of 32 probands (50%) carried PPV in 15 of 326 genes, including 14 RetNet genes and one anterior segment dysgenesis-associated gene. Of these 16 probands with PPV, five (55.56%) were from the group of nine probands with both had PACG and RP and 11 (47.83%) were from the group of 23 probands with PACG alone. Of the 15 genes, five genes, CRB1, COL2A1, RHO, RP1L1, and PAX6, were reported to cause phenotypes including glaucoma. The variants in RetNet genes appeared to be associated with a significant proportion of PACG, especially in probands with both PACG and RP. These findings enrich the phenotype spectrum of RetNet genes and provide clues for genetic screening for glaucoma. Our study suggests a genetic association between PACG and RP, although the cause-effect relationship between them needs further validation.

PURPOSE: To investigate the predictors of long-term intraocular pressure (IOP) in chronic primary angle-closure glaucoma (CPACG) treated with primary trabeculectomy. METHODS: This study systematically reviewed cases of CPACG treated with primary trabeculectomy. The scleral flaps in all cases were sutured with two stitches in situ and two releasable sutures to ensure watertight under normal IOP conditions during surgery. Mitomycin C was used in all eyes. All patients were followed for 2 years. Digital massage of the bulbus and removal of the releasable suture were performed according to the IOP and shape of the filtering bleb. Demographic data and clinical outcomes were recorded. Factors predicting long-term IOP were identified. RESULTS: A total of 72 patients (88 eyes) with a mean age of 58.51 ± 10.60 years were included in this study. The complete success rate was 89.77% after 2 years. The IOP began to stabilize after 7 days and reached its lowest point at the 1-month follow-up. The preoperative and early postoperative high or low IOP does not affect long-term effects (P > 0.05). There was a positive correlation between postoperative IOP at the 1-month and 2-year follow-ups (r = 0.64, P < 0.001). CONCLUSION: In CPACG patients undergoing primary trabeculectomy, scleral flaps sutured watertightly with two stitches in situ and two releasable sutures under normal IOP conditions can ensure controllable, effective and safe treatment of CPACG. The preoperative and early postoperative high or low IOP does not affect long-term effects. One-month postoperative IOP can be used as a predictor of long-term IOP control.

OBJECTIVE: In Taiwan, the number of medical disputes and litigation has increased dramatically over the past 20 years. The seriousness of medical disputes continuing grows in clinical practice, especially in obstetricians. This study provided a possible solution to the medical dispute litigation issue. MATERIALS AND METHODS: The Ministry of Health and Welfare (MOHW) compensation program for birth incidents has been implemented since 2012 and it provided pecuniary compensation for mothers, newborns, and fetuses who got injured or died in birth-related medical incidents. We analyzed the amount and distribution of compensation, and assessed the effect of compensation on the number of medical dispute litigation. RESULTS: From 2012 to 2015, a total of 348 applications was received, 322 of which were examined by the committee. Among the examined cases, 278 were approved for compensation. The total amount of compensation had reached 266.16 million NTD (8.32 million USD). For the medical dispute litigation, a dramatic decrease in number was observed after the implementation of this compensation pilot program. CONCLUSION: Prompt compensation provided instant economic and spiritual support for patients and families. Pecuniary compensation could be an alternative choice of justice, which might encourage the injured to receive economic compensation, instead of filing a lawsuit against the physician or hospital institution. As a result, the number of dispute litigation has decreased. This indicates that the compensation program is an efficient way to improve medical dispute litigation difficulties.

A one-pot and two-step reaction of four components, including aldehydes, Fmoc-protected α-amino acid, isocyanide, and soluble polymer-supported 4-fluoro-3-amino benzoate ester, was developed for an efficient synthesis of dihydroquinoxalinones under microwave irradiation. Fmoc deprotection followed by intramolecular cyclization of the diamide gave a facile access to novel bicyclic quinoxalin-2-ones. On the basis of this approach, a new route to synthesize this privileged scaffold from the diamide intermediate was designed and accomplished with high yields. Use of multicomponent reaction (MCR) has been shown to display a good functional group tolerance, while the product isolation and purification is straightforward by precipitation and washings. Current library discusses the synthesis and diversification of 21 compounds produced using this strategy.
