The correlation between dietary inflammatory index and risk of hyperuricemia in the U.S. population.

The dietary inflammatory index (DII) has been reported to be related to chronic diseases as a novel inflammatory marker. However, the correlation between DII score and hyperuricemia in adults in the United States is still unclear. Therefore, our goal was to explore the correlation between them. A total of 19,004 adults were enrolled in the National Health and Nutrition Examination Survey from 2011 to 2018. DII score was calculated according to 28 dietary items obtained by 24-hour dietary interview data. Hyperuricemia was defined by serum uric acid level. We used multilevel logistic regression models and subgroup analysis to determine whether the 2 were associated. DII scores were positively associated with serum uric acid and the risk of hyperuricemia. Per unit increased in DII score was associated with a 3 mmol/L increase in serum uric acid in males (ß 3.00, 95% confidence interval (CI) 2.05-3.94) and 0.92mmol/L in females (ß 0.92, 95% CI 0.07-1.77), respectively. Compared with the lowest tertile of DII score, the rise of DII grade increased the risk of hyperuricemia among the whole participants (T2: odds ratio (OR) 1.14, 95% CI 1.03, 1.27; T3: OR 1.20 [1.07, 1.34], P for trend = .0012) and males [T2: 1.15 (0.99, 1.33), T3: 1.29 (1.11, 1.50), P for trend = .0008]. For females, the correlation between DII score and hyperuricemia was statistically significant in the subgroup stratified by body mass index (BMI) (BMI < 30, OR 1.08, 95% CI 1.02-1.14, P for interaction = .0134), which indicates that the association depends on BMI. In the United States male population, the DII score has a positive correlation with hyperuricemia. Anti-inflammatory dietary intake can be beneficial for lower serum uric acid.

Recurrence risk factors of intravitreal ranibizumab monotherapy in retinopathy of prematurity: a retrospective study at one center.

AIM: To identify risk factors of recurrence of this disorder after intravitreal ranibizumab (IVR) monotherapy. METHODS: Totally 33 eyes of 19 patients who underwent initial IVR treatments for type 1 retinopathy of prematurity (ROP) at our center were retrospectively reviewed between April 1, 2016 and December 31, 2017. Patient demographics, the side of ROP, multiple gestations, Apgar scores, zone, stage, plus disease, postmenstrual age at injection, surfactant therapy, blood transfusion therapy, hemorrhage before IVR, hemorrhage after IVR, gestational diabetes mellitus, pregnancy-induced hypertension, anemia, intraventricular hemorrhage, sepsis, respiratory distress syndrome, carbohemia, and congenital heart defects were recorded. Adjusted hazard ratios (HRs) and 95% confidence intervals were determined after adjusting for potential confounders using multivariate proportional Cox regression. RESULTS: Of the 33 eyes, 12 (36.4%) had ROP recurrences 45.3 (5.1, 50.9)mo after initial IVR treatments. The independent risk factors for ROP recurrences were zone (II vs I, HR: 0.056, P=0.003) and gestational diabetes mellitus (no vs yes, HR: 0.095, P<0.001). The mean uncorrected visual acuity for four recurrence eyes was 0.46 logMAR (0.13, 0.70) at 55.0 (51.0, 58.9) mo after the initial IVR treatment. The mean uncorrected visual acuity for 10 eyes without recurrence was 0.46 logMAR (0.19, 0.63) at 48.0 (43.8, 58.4) mo after the initial IVR treatment. CONCLUSION: Two independent risk factors for type 1 ROP recurrence after IVR treatment involving zone I and gestational diabetes mellitus are identified, and the mean uncorrected visual acuity is 0.46 logMAR at 51.0 (44.0, 58.9)mo. The findings of this study are important for follow-up management and for improving the visual function of ROP patients.

Impact of dialysis modality choice on the survival of end-stage renal disease patients with congestive heart failure in southern China: A retrospective cohort study.

Background and object: Heart failure is one of the common complications in patients with end-stage renal disease (ESRD) and a major cause of death in these patients. The choice of dialysis modality for ESRD patients with congestive heart failure (CHF) is still inconclusive. The purpose of this study was to compare the prognosis of hemodialysis (HD) and peritoneal dialysis (PD) among ESRD patients with CHF and provide a basis for clinical decision-making. Materials and methods: This was a retrospective study conducted at Guangdong Provincial Hospital of Traditional Chinese Medicine that included patients with CHF requiring long-term renal replacement therapy between January 1, 2012 and December 31, 2017. The end of follow-up was December 31, 2020. All patients were divided into HD and PD groups and sub grouped by age, and we used univariate and multifactorial Cox regression analyses to calculate the relative hazard ratios (HR) of the different dialysis types and adjusted for differences in baseline data using propensity score matching (PSM). Result: A total of 121 patients with PD and 156 patients with HD were included in this study. Among younger ESRD patients (≤65 years of age) with CHF, the prognosis of HD was worse than that of PD [HR = 1.84, 95% confidence interval (CI) = 1.01-3.34], and this disadvantage remained significant in the fully adjusted model [sex, age at dialysis initiation, Charlson comorbidities index, body mass index, prealbumin, hemoglobin, and left ventricular ejection fraction (LVEF)] and after PSM. In the older group (>65 years of age), the prognosis of HD was better than that of PD (HR = 0.46, 95% CI = 0.25-0.85), and the protective effect remained in the fully adjusted model and after PSM. The aforementioned survival differences across the cohort were maintained in patients with preserved LVEF (>55%), but could not be reproduced in patients with reduced LVEF (≤55%). Conclusion: In southern China, PD is a better choice for younger patients with ESRD, CHF and preserved LVEF, and HD is the better option for older patients.

Auricular Acupressure for Hemodialysis Patients with Insomnia: A Multicenter Double-Blind Randomized Sham-Controlled Trial.

Background and objectives: The effect of auricular acupressure (AA) for maintenance hemodialysis (MHD) patients with insomnia has been controversial. This study assessed the efficacy and safety of AA for MHD patients with chronic insomnia. Design, setting, participants, and measurements: This was a multicenter, double-blind (participant and assessor), randomized sham-controlled trial. A total of 133 subjects were randomized to receive AA on active points (AA group, n = 64) or on sham auricular acupressure (SAA) points (SAA group, n = 69) for 8 weeks and followed up for 12 weeks. AA was provided by assigned qualified nurses who were not involved in assessment. The primary outcome was the clinical response rate, which was defined as the percentage of participants who reached a reduction of Pittsburgh Sleep Quality Index (PSQI) global score ≥3 in each group. Secondary outcomes included changes in PSQI scores over time, PSQI scores and hypnotics use at each visit, and changes in the weekly dose of hypnotics for drug-dependent subjects. Results: At week 8, the AA group yielded a higher clinical response rate than the SAA group (AA: 55% vs. SAA: 36%, odds ratio: 1.5, 95% confidence interval: 1.0-2.2, p = 0.033). Both groups showed a reduction in PSQI global scores during treatment and follow-up, compared with the baseline, respectively. A significant change of PSQI global score was observed over time (F = 28.387, p < 0.001). PSQI global score of the AA group was relatively lower than that of the SAA group at each visit (p < 0.05 at week 16 and 20). For those depending on hypnotics, AA reduced their consumption of hypnotics. The intervention was safe, and its adherence was satisfactory. Conclusion: AA could serve as a complementary or alternative therapy for MHD patients with insomnia by improving their sleep quality and reducing their use of hypnotics.

Propensity-matched comparison of mortality between peritoneal dialysis and hemodialysis in patients with type 2 diabetes.

BACKGROUND: The optimal choice of dialysis modality for diabetic patients remains controversial. This study aimed to compare mortality between peritoneal dialysis (PD) and hemodialysis (HD) in end-stage renal disease (ESRD) patients with type 2 diabetes (T2D). METHODS: Our observational, longitudinal cohort consisted of all incident ESRD patients with T2D who received either PD or HD in our center from January 2012 to December 2017 and were followed until December 2019. Propensity scores were used to select a 1:1 matched cohort. Mortality was compared between dialysis modalities using Kaplan-Meier survival analysis, and risk factors for mortality were estimated using multivariate Cox regression analyses. RESULTS: The median follow-up times were 35.5 months in the PD group (n = 134) and 41.6 months in the HD group (n = 134, p = 0.0381). The 1-, 2-, 3-, 5-, and 7-year patient survival rates were 98%, 91%, 77%, 61%, and 35% for diabetic PD patients and 96%, 88%, 81%, 60%, and 57% for diabetic HD patients. Kaplan-Meier survival analysis showed that overall mortality did not significantly differ between modalities (log-rank = 0.9473, p = 0.6575). Using a multivariate Cox regression model, advanced age and increased cholesterol at the initiation of PD treatment were independent risk factors associated with mortality, whereas under HD therapy, the risk factors associated with mortality were lower BMI and higher HbA1c. CONCLUSIONS: These results suggest that in patients with T2D, mortality is comparable between PD and HD irrespective of whether there are the first 2 years or over the 2-year period, and that different mortality predictor patterns exist between patients treated with PD versus HD.

Effectiveness of Chinese herbal medicine combined with Western medicine on deferring dialysis initiation for nondialysis chronic kidney disease stage 5 patients: a multicenter prospective nonrandomized controlled study.

BACKGROUND: In clinical practice, Chinese herbal medicine (CHM) purportedly has beneficial therapeutic effects for chronic kidney disease (CKD), which include delaying disease progression and dialysis initiation. However, there is a lack of high-quality evidence-based results to support this. Therefore, this study aimed to evaluate the efficacy of CHM combined with Western medicine in the treatment of stage 5 CKD. METHODS: This was a prospective nonrandomized controlled study. Stage 5 CKD (nondialysis) patients were recruited form 29 AAA class hospitals across China from July 2014 to April 2019. According to doctors' advice and the patients' wishes, patients were assigned to the CHM group (Western medicine + CHM) and the non-CHM group (Western medicine). Patient demographic data, primary disease, blood pressure, Chinese and Western medical drugs, clinical test results, and time of dialysis initiation were collected during follow-up. RESULTS: A total of 908 patients were recruited in this study, and 814 patients were finally included for further analysis, including 747 patients in the CHM group and 67 patients in the non-CHM group. 482 patients in the CHM group and 52 patients in the non-CHM group initiated dialysis. The median time of initiating dialysis was 9 (7.90, 10.10) and 3 (0.98,5.02) months in the CHM group and non-CHM group, respectively. The multivariate Cox regression analysis showed that patients in the CHM group had a significantly lower risk of dialysis [adjusted hazard ratio (aHR): 0.38; 95% confidence interval (CI): 0.28, 0.53] compared to those in the non-CHM group. After 1:2 matching, the outcomes of 160 patients were analyzed. The multivariate Cox regression analysis showed that patients in the CHM group had a significantly lower risk of dialysis (aHR: 0.32; 95% CI: 0.21, 0.48) compared to patients in the non-CHM group. Also, the Kaplan-Meier analysis demonstrated that the cumulative incidence of dialysis in the CHM group was significantly lower than that in the non-CHM group (log-rank test, P<0.001) before and after matching. CONCLUSIONS: This study suggest that the combination of CHM and Western medicine could effectively reduce the incidence of dialysis and delay the time of dialysis initiation in stage 5 CKD patients.

Effects of dialysis modality choice on the survival of end-stage renal disease patients in southern China: a retrospective cohort study.

BACKGROUND: The optimal choice of treatment, with hemodialysis (HD) or peritoneal dialysis (PD), for end-stage renal disease (ESRD) patients, is still controversial. Only a few studies comparing HD and PD have been conducted in China, which has the largest number of dialysis patients in the world. METHODS: A retrospective cohort study was conducted on ESRD patients who began renal replacement treatment from January 1, 2012 to December 31, 2017 in Guangdong Provincial Hospital of Chinese Medicine. Propensity scoring match was applied to balance the baseline conditions and multivariate Cox regression analysis to compare the mortality between HD and PD patients, and evaluated the correlation between mortality and various baseline characteristics. RESULTS: A total of 436 HD patients and 501 PD patients were included in this study, and PD patients had better survival than HD patients, but the difference was not statistically significant. For younger ESRD patients (≤60-year-old), the overall survival of PD was better than that of HD, but HD was associated with a lower risk of death in older patients (> 70-year-old). This difference was still significant after adjustment for a variety of confounding factors. Female gender, age at dialysis initiation, cardiovascular disease, cholesterol, and HD were risk factors of all-cause mortality in the younger subgroup, while PD was risk factor in the older subgroup. CONCLUSION: PD may be a better choice for younger ESRD patients, and HD for the older patients.

Bupi Yishen Formula Versus Losartan for Non-Diabetic Stage 4 Chronic Kidney Disease: A Randomized Controlled Trial.

Chinese herbal medicine (CHM) might have benefits in patients with non-diabetic chronic kidney disease (CKD), but there is a lack of high-quality evidence, especially in CKD4. This study aimed to assess the efficacy and safety of Bupi Yishen Formula (BYF) vs. losartan in patients with non-diabetic CKD4. This trial was a multicenter, double-blind, double-dummy, randomized controlled trial that was carried out from 11-08-2011 to 07-20-2015. Patients were assigned (1:1) to receive either BYF or losartan for 48 weeks. The primary outcome was the change in the slope of the estimated glomerular filtration rate (eGFR) over 48 weeks. The secondary outcomes were the composite of end-stage kidney disease, death, doubling of serum creatinine, stroke, and cardiovascular events. A total of 567 patients were randomized to BYF (n = 283) or losartan (n = 284); of these, 549 (97%) patients were included in the final analysis. The BYF group had a slower renal function decline particularly prior to 12 weeks over the 48-week duration (between-group mean difference of eGFR slopes: -2.25 ml/min/1.73 m2/year, 95% confidence interval [CI]: -4.03,-0.47), and a lower risk of composite outcome of death from any cause, doubling of serum creatinine level, end-stage kidney disease (ESKD), stroke, or cardiovascular events (adjusted hazard ratio = 0.61, 95%CI: 0.44,0.85). No significant between-group differences were observed in the incidence of adverse events. We conclude that BYF might have renoprotective effects among non-diabetic patients with CKD4 in the first 12 weeks and over 48 weeks, but longer follow-up is required to evaluate the long-term effects.

Auricular acupressure for insomnia in hemodialysis patients: study protocol for a randomized controlled trial.

BACKGROUND: Patients on maintenance hemodialysis (MHD) frequently complain of insomnia. Poor sleep quality impairs their quality of life and adversely affects long-term outcome. Previously we applied auricular acupressure therapy (AAT) for MHD patients with insomnia and yielded favorable results. AAT probably improves sleep quality by stimulating the vagus nerve and inhibiting sympathetic overactivity. However, the efficacy of AAT for insomnia in this population is still lacking. The proposed randomized controlled trial (RCT) will evaluate the efficacy and safety of AAT for improvement of sleep quality in MHD patients with insomnia. METHODS/DESIGN: The proposed study is a multi-center, double-blind (participants and assessors), parallel-group RCT. A total of 112 participants with insomnia will be recruited from six hemodialysis centers in Guangzhou, China, and randomly allocated in a 1:1 ratio to receive auricular acupressure on either active points (AA group) or control points (points irrelevant to insomnia management, SAA group). The treatment will last for 8 weeks prior to a follow-up period of 12 weeks. Evaluation by blinded assessors at baseline, at 8 weeks (end of treatment) as well as at 4-week, 8-week and 12-week follow-ups (after intervention) will include Pittsburgh Sleep Quality Index (PSQI) scores and average weekly dose of hypnotics. The primary endpoint is clinical response rate (percentage of participants who reach a reduction of PSQI global score ≥ 3 in each group) at 8 weeks from baseline. Secondary endpoints include the changes in PSQI scores over time from baseline, as well as the changes in weekly dose of hypnotics. DISCUSSION: This paper describes the rationale and design of a double-blind RCT that aims to determine the efficacy and safety of AAT for insomnia of hemodialysis patients. If successful, this project will provide evidence of the efficacy and safety of AAT for insomnia of hemodialysis patients. TRIAL REGISTRATION: ClinicalTrials.gov , Identifier: NCT03015766 .

Rationale and design of the Helping Ease Renal failure with Bupi Yishen compared with the Angiotensin II Antagonist Losartan (HERBAAL) trial: a randomized controlled trial in non-diabetes stage 4 chronic kidney disease.

BACKGROUND: Chronic kidney disease (CKD) is a global public health problem. Currently, as for advanced CKD populations, medication options limited in angiotensin-converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARB), which were partially effective. A Chinese herbal compound, Bupi Yishen formula, has showed renal protective potential in experiments and retrospective studies. This study will evaluate the efficacy and safety of Bupi Yishen formula (BYF) in patients with CKD stage 4. DESIGN: In this double blind, double dummy, randomized controlled trial (RCT), there will be 554 non-diabetes stage 4 CKD patients from 16 hospitals included and randomized into two groups: Chinese medicine (CM) group or losartan group. All patients will receive basic conventional therapy. Patients in CM group will be treated with BYF daily while patients in control group will receive losartan 100 mg daily for one year. The primary outcome is the change in estimated glomerular filtration rate (eGFR) over 12 months. Secondary outcomes include the incidence of endpoint events, liver and kidney function, urinary protein creatinine ratio, cardiovascular function and quality of life. DISCUSSION: This study will be the first multi-center, double blind RCT to assess whether BYF, compared with losartan, will have beneficial effects on eGFR for non-diabetes stage 4 CKD patients. The results will help to provide evidence-based recommendations for clinicians. TRIAL REGISTRATION: Chinese Clinical Trial Registry Number: ChiCTR-TRC-10001518 .

Ten-year etiologic review of Chinese children hospitalized for pediatric cataracts.

PURPOSE: Our aim was to obtain a better understanding of the etiologies and characteristics of pediatric cataracts treated at a single facility in China. METHODS: Medical records accrued over a 10-year period (from August, 2003 to July, 2013) at Shengjing Hospital of China Medical University were reviewed retrospectively, identifying all patients treated for various subtypes of pediatric cataract. A database with 367 subjects under 14 years of age (598, including second-round surgeries) was generated. RESULTS: Of this cohort (n = 367; males: 232, 63.2%; females: 135, 36.8%), 200 patients (54.5%) had bilateral cataracts, and 258 (70.3%) were under 3 years of age. In all age groups and in all subtypes of pediatric cataract, males were most commonly affected. Congenital cataract was the most prevalent subtype, accounting for 296 patients (80.7%). Most congenital cataracts were associated with other ocular or systemic abnormalities; and in 48 patients (16.22%), they were hereditary. Traumatic cataract was the most common subtype (85.92%) of acquired cataract. The few instances of cataracts due to steroids (n = 3) or to metabolic disorders (n = 2) occurred in males and involved both eyes. CONCLUSION: The majority of pediatric cataracts in this patient population were congenital in nature. A significant lag in ophthalmologic evaluation of Chinese infants was evident and should be addressed by educating both children and parents on risk factors for cataract development. Regular assessments are especially important in children subjected to long-term systemic steroid treatments.

Rapid bilateral anterior capsule contraction following high myopic cataract surgeries: a case report.

We describe a rapid anterior capsule contraction following phacoemulsifiction and intraocular lens(IOL) implantation in an old woman with high myopia. The patient with high myopia complicated with cataract received phacoemulcification and IOL implantation bilaterally .The best-corrected visual acuity (BCVA) improved from 0.1 to 0.4 in the right eye and 0.5 in the left eye 1 week after surgeries.5 weeks after surgery of the right eye and 4 weeks after surgery of the left eye, the patient complained blurred vision in the right eye. BCVA of the right eye was 0.06 and that of the left was 0.1. Slit-lamp examination revealed anterior capsule contraction in both eyes and a fully closed capsulorhexis opening in the right eye. The IOLs were centered but almost completely enclosed, with numerous linear fibrous folds radiating from the hick central fibrosis. We surgically excised the central part of the anterior capsule of the eyes with microscissors, resulting again in BCVA of 0.4 and 0.5 in the right and left eyes respectively. Anterior capsule contraction might appear much earlier than three months after phacoemulsification and IOL implantation surgery in case of high myopia complicated with cataract. Patients with high myopia receive cataract and IOL surgery should be monitored carefully for the rapid development of anterior capsule contraction.
