Association between alcohol consumption and chronic kidney disease: a population-based survey.

BACKGROUND: Alcohol consumption is associated with both beneficial and harmful effects, and the role of alcohol consumption in chronic kidney disease (CKD) remains inconclusive. This study aimed to investigate the relationship between alcohol consumption and CKD or estimated glomerular filtration rate (eGFR). METHODS: This study enrolled adults from the second Taiwanese Survey on Prevalences of Hypertension, Hyperglycemia, and Hyperlipidemia, conducted in 2007. Participants were categorized into frequent drinkers, occasional drinkers, and nondrinkers. The amount of alcohol consumption was assessed by standard drinks per week. The primary outcome was the presence of CKD, and the secondary outcome was the eGFR. RESULTS: Among 3967 participants with a mean age of 47.9 years and a CKD prevalence of 11.7%, 13.8% were frequent drinkers, and 23.1% were occasional drinkers. The average amount of alcohol consumed was 3.3 drinks per week. Frequent drinkers (odds ratio [OR] 0.622, 95% confidence interval [CI] 0.443-0.874) and occasional drinkers (OR 0.597 95% CI 0.434-0.821) showed a lower prevalence of CKD than nondrinkers. Consumption of a larger number of standard drinks was associated with a lower prevalence of CKD (OR 0.872, 95% CI 0.781-0.975). Frequent drinkers and those who consumed a larger number of standard drinks per week showed higher eGFRs. CONCLUSION: Within the range of moderate alcohol intake, those who consumed more alcohol had a higher eGFR and reduced prevalence of CKD. The potentially harmful effects of heavy drinking should be taken into consideration, and alcohol intake should be limited to less than light to moderate levels.

Glucosamine Enhancement of Learning and Memory Functions by Promoting Fibroblast Growth Factor 21 Production.

Fibroblast growth factor 21 (FGF21) plays a crucial role in metabolism and brain function. Glucosamine (GLN) has been recognized for its diverse beneficial effects. This study aimed to elucidate the modulation of FGF21 production by GLN and its impact on learning and memory functions. Using both in vivo and in vitro models, we investigated the effects of GLN on mice fed with a normal diet or high-fat diet and on mouse HT22 hippocampal cells, STHdhQ7/Q7 striatal cells, and rat primary cortical neurons challenged with GLN. Our results indicated that GLN promotes learning and memory functions in mice and upregulates FGF21 expression in the hippocampus, cortex, and striatum, as well as in HT22 cells, STHdhQ7/Q7 cells, and cortical neurons. In animals receiving GLN together with an FGF21 receptor FGFR1 inhibitor (PD173074), the GLN-enhanced learning and memory functions and induction of FGF21 production in the hippocampus were significantly attenuated. While exploring the underlying molecular mechanisms, the potential involvement of NF-κB, Akt, p38, JNK, PKA, and PPARα in HT22 and NF-κB, Akt, p38, and PPARα in STHdhQ7/Q7 were noted; GLN was able to mediate the activation of p65, Akt, p38, and CREB in HT22 and p65, Akt, and p38 in STHdhQ7/Q7 cells. Our accumulated findings suggest that GLN may increase learning and memory functions by inducing FGF21 production in the brain. This induction appears to be mediated, at least in part, through GLN's activation of the NF-κB, Akt, p38, and PKA/CREB pathways.

Physician Compliance With a Computerized Clinical Decision Support System for Anemia Management of Patients With End-stage Kidney Disease on Hemodialysis: Retrospective Electronic Health Record Observational Study.

BACKGROUND: Previous studies on clinical decision support systems (CDSSs) for the management of renal anemia in patients with end-stage kidney disease undergoing hemodialysis have previously focused solely on the effects of the CDSS. However, the role of physician compliance in the efficacy of the CDSS remains ill-defined. OBJECTIVE: We aimed to investigate whether physician compliance was an intermediate variable between the CDSS and the management outcomes of renal anemia. METHODS: We extracted the electronic health records of patients with end-stage kidney disease on hemodialysis at the Far Eastern Memorial Hospital Hemodialysis Center (FEMHHC) from 2016 to 2020. FEMHHC implemented a rule-based CDSS for the management of renal anemia in 2019. We compared the clinical outcomes of renal anemia between the pre- and post-CDSS periods using random intercept models. Hemoglobin levels of 10 to 12 g/dL were defined as the on-target range. Physician compliance was defined as the concordance of adjustments of the erythropoietin-stimulating agent (ESA) between the CDSS recommendations and the actual physician prescriptions. RESULTS: We included 717 eligible patients on hemodialysis (mean age 62.9, SD 11.6 years; male n=430, 59.9%) with a total of 36,091 hemoglobin measurements (average hemoglobin and on-target rate were 11.1, SD 1.4, g/dL and 59.9%, respectively). The on-target rate decreased from 61.3% (pre-CDSS) to 56.2% (post-CDSS) owing to a high hemoglobin percentage of >12 g/dL (pre: 21.5%; post: 29%). The failure rate (hemoglobin <10 g/dL) decreased from 17.2% (pre-CDSS) to 14.8% (post-CDSS). The average weekly ESA use of 5848 (SD 4211) units per week did not differ between phases. The overall concordance between CDSS recommendations and physician prescriptions was 62.3%. The CDSS concordance increased from 56.2% to 78.6%. In the adjusted random intercept model, the post-CDSS phase showed increased hemoglobin by 0.17 (95% CI 0.14-0.21) g/dL, weekly ESA by 264 (95% CI 158-371) units per week, and 3.4-fold (95% CI 3.1-3.6) increased concordance rate. However, the on-target rate (29%; odds ratio 0.71, 95% CI 0.66-0.75) and failure rate (16%; odds ratio 0.84, 95% CI 0.76-0.92) were reduced. After additional adjustments for concordance in the full models, increased hemoglobin and decreased on-target rate tended toward attenuation (from 0.17 to 0.13 g/dL and 0.71 to 0.73 g/dL, respectively). Increased ESA and decreased failure rate were completely mediated by physician compliance (from 264 to 50 units and 0.84 to 0.97, respectively). CONCLUSIONS: Our results confirmed that physician compliance was a complete intermediate factor accounting for the efficacy of the CDSS. The CDSS reduced failure rates of anemia management through physician compliance. Our study highlights the importance of optimizing physician compliance in the design and implementation of CDSSs to improve patient outcomes.

Ultraviolet B phototherapy does not increase the risk of skin cancer among patients with atopic dermatitis: A population-based retrospective cohort study.

BACKGROUND: UV-B phototherapy is a common treatment modality for patients with atopic dermatitis (AD), but its long-term safety in terms of cutaneous carcinogenic risk has not been studied. OBJECTIVE: To investigate the risk of skin cancer among patients with AD receiving UV-B phototherapy. METHODS: We conducted a nationwide population-based cohort study from 2001 to 2018 to estimate the risk of UV-B phototherapy for skin cancer, nonmelanoma skin cancer, and cutaneous melanoma in patients with AD. RESULTS: Among 6205 patients with AD, the risks of skin cancer (adjusted hazard ratio [HR], 0.91; 95% CI, 0.35-2.35), nonmelanoma skin cancer (adjusted HR, 0.80; 95% CI, 0.29-2.26), and cutaneous melanoma (adjusted HR, 0.80; 95% CI, 0.08-7.64) did not increase among patients with AD treated with UV-B phototherapy, compared with those who did not receive UV-B phototherapy. Additionally, the number of UV-B phototherapy sessions was not associated with an increased risk of skin cancer (adjusted HR, 0.99; 95% CI, 0.96-1.02), nonmelanoma skin cancer (adjusted HR, 0.99; 95% CI, 0.96-1.03), or cutaneous melanoma (adjusted HR, 0.94; 95% CI, 0.77-1.15). LIMITATIONS: Retrospective study. CONCLUSION: Neither UV-B phototherapy nor the number of UV-B phototherapy sessions was associated with an increased risk of skin cancers among patients with AD.

Comparative efficacy of treatments for molluscum contagiosum: A systematic review and network meta-analysis.

BACKGROUND AND OBJECTIVES: Various interventions have been applied to treat molluscum contagiosum, but benefits and efficacy remain unclear. To assess the comparative efficacy and safety of interventions for molluscum contagiosum, a network meta-analysis was performed. PATIENTS AND METHODS: Embase, PubMed, and the Cochrane Library were searched for articles published between January 1, 1990, and November 31, 2020. Eligible studies were randomized clinical trials (RCTs) of interventions in immunocompetent children and adults with genital/non-genital molluscum contagiosum lesions. RESULTS: Twelve interventions from 25 RCTs including 2,123 participants were assessed. Compared with the placebo, ingenol mebutate had the most significant effect on complete clearance (odds ratio [OR] 117.42, 95% confidence interval [CI] 6.37-2164.88), followed by cryotherapy (OR 16.81, 95% CI 4.13-68.54), podophyllotoxin (OR 10.24, 95% CI 3.36-31.21), and potassium hydroxide (KOH) (OR 10.02, 95% CI 4.64-21.64). Data on adverse effects were too scarce for quantitative synthesis. CONCLUSIONS: Ingenol mebutate, cryotherapy, podophyllotoxin, and KOH were more effective than the other interventions in achieving complete clearance, but safety concerns regarding ingenol mebutate have recently been reported. Due to the possibility of spontaneous resolution, observation is also justified for asymptomatic infection. Factors including adverse effects, cost, patient preference, and medical accessibility should be considered.

Short-Term Effects of a Therapeutic Diet on Biochemical Parameters in Hemodialysis Patients: A Randomized Crossover Trial.

OBJECTIVE: Although unhealthy diets exacerbate nutritional and metabolic derangements in patients with end-stage kidney disease (ESKD), how therapeutic diets that possess a variety of different dietary strategies acutely modify diverse biochemical parameters related to cardiovascular disease remains underexplored. METHODS: Thirty-three adults with end-stage kidney disease undergoing thrice-weekly hemodialysis participated in a randomized crossover trial comparing a therapeutic diet with their usual diets for 7 days, separated by a 4-week washout period. The therapeutic diet was characterized by adequate calorie and protein amounts, natural food ingredients with a low phosphorus-to-protein ratio, higher portions of plant-based food, and high fiber content. The primary outcome measure was the mean difference in the change-from-baseline intact fibroblast growth factor 23 (FGF23) level between the 2 diets. The other outcomes of interest included changes in mineral parameters, uremic toxins, and high-sensitivity C-reactive protein (hs-CRP) levels. RESULTS: Compared with the usual diet, the therapeutic diet lowered intact FGF23 levels (P = .001), decreased serum phosphate levels (P < .001), reduced intact parathyroid hormone (PTH) levels (P = .003), lowered C-terminal FGF23 levels (P = .03), increased serum calcium levels (P = .01), and tended to lower total indoxyl sulfate levels (P = .07) but had no significant effect on hs-CRP levels. Among these changes, reduction in serum phosphate level achieved in 2 days, modifications of intact PTH and calcium levels in 5 days, and reductions in intact and C-terminal FGF23 levels in 7 days of therapeutic diet intervention. CONCLUSION: Within the 1-week intervention period, the dialysis-specific therapeutic diet rapidly reversed mineral abnormalities and tended to decrease total indoxyl sulfate levels in patients undergoing hemodialysis but had no effect on inflammation. Future studies to assess the long-term effects of such therapeutic diets are recommended.

Extremely Low Dose of Erythropoiesis-Stimulating Agent May Be Associated with Increased Mortality in Hemodialysis Patients.

INTRODUCTION: Although high-dose erythropoiesis-stimulating agent (ESA) has been shown to increase mortality risk and adverse cardiovascular events in hemodialysis patients, the safety of extremely low-dose ESA is unclear. METHODS: We retrospectively analyzed the association between ESA dose and mortality in the monthly dosing range of 0-43,000 U of equivalent epoetin alfa in 304 Taiwan hemodialysis patients by using Cox proportional hazard model and cubic spline model. RESULTS: Compared with mean monthly ESA dose of 15,000-25,000 U (mean ± standard deviation 20,609 ± 2,662 U), monthly ESA dose of less than 15,000 U (mean ± standard deviation 7,413 ± 4,510 U) is associated with increased mortality. Monthly ESA dose of 25,001-43,000 U (mean ± standard deviation 31,160 ± 4,304 U) is not associated with higher mortality risk than monthly ESA dose of 15,000-25,000 U. The results were consistent in Cox proportional hazard models and cubic spline models. Subgroup analyses showed no significant heterogeneities among prespecified subgroups. CONCLUSIONS: Extremely low dose of ESA in hemodialysis patients may be associated with increased mortality risk. Future studies are warranted to prove this association.

Adverse events following the first, second and third doses of a COVID-19 vaccine in hemodialysis patients.

BACKGROUND: This study aimed to identify adverse events following the first three doses of COVID-19 vaccines in hemodialysis (HD) patients. Risk factors associated with postvaccination adverse events were explored. METHODS: Postvaccination adverse events in 438 HD patients who received 3 doses of COVID-19 vaccines were prospectively assessed. The adverse events among three doses were compared using generalized linear mixed models. Factors associated with adverse events were assessed with multivariate analyses. RESULTS: The vast majority of participants received Oxford/AstraZeneca ChAdOx1 as their first two doses and Moderna mRNA-1273 as their third dose. Overall, 79%, 50% and 84% of the participants experienced at least one adverse event after their first, second, and third doses, respectively. These adverse events were mostly minor, short-lived and less than 5% reported daily activities being affected. Compared with the first dose, the second dose caused a lower rate of adverse events. Compared with the first dose, the third dose elicited a higher rate of injection site reactions and a lower rate of systemic reactions. Multivariate analyses showed that every 10-year increase of age (odds ratio 0.67, 95% confidence intervals 0.57-0.79) was associated with decreased risk of adverse events, while female sex (2.82, 1.90-4.18) and arteriovenous fistula (1.73, 1.05-2.84) were associated with increased risk of adverse events. Compared with Oxford/AstraZeneca ChAdOx1, Moderna mRNA-1273 was associated with an increased risk of injection site reactions. CONCLUSIONS: COVID-19 vaccination was well tolerated in HD patients. Age, sex, dialysis vascular access and vaccine types were associated with postvaccination adverse events.

Uremic pruritus: pathophysiology, clinical presentation, and treatments.

Uremic pruritus is one of the most common and bothersome symptoms in patients with end-stage renal disease. Most patients with uremic pruritus experience a prolonged and relapsing course and significant impairments of quality of life. The pathophysiology of uremic pruritus is not completely understood. A complex interplay among cutaneous biology and the nervous and immune systems has been implicated, with the involvement of various inflammatory mediators, neurotransmitters, and opioids. Uremic pruritus treatment outcomes are often unsatisfactory. Clinical trials have mostly been small in scale and have reported inconsistent results. Recent evidence shows that gabapentinoids, nalfurafine, and difelikefalin are effective for relieving uremic pruritus in hemodialysis patients. This review provides an overview of the epidemiology and proposed mechanisms of uremic pruritus, then highlights the manifestations of and clinical approach to uremic pruritus. Current evidence regarding treatment options, including topical treatments, treatment of underlying disease, phototherapy, and systemic treatments, is also outlined. With a better understanding of uremic pruritus, more therapeutic options can be expected in the near future.

Microbiota analysis in the hemodialysis population - Focusing on Enterobacteriaceae.

BACKGROUND: Infection is a recognized risk factor for mortality among hemodialysis (HD) population, including infection caused by Enterobacteriaceae. We aimed to investigate Enterobacteriaceae in gut microbiota among HD patients and to analyze associations between microbiota and clinical parameters. METHODS: This prospective study of microbiota analysis in HD patients was conducted in April-May 2019. A control group without recent antibiotic use or hospitalization was used for comparison. Stool samples underwent 16S rRNA sequencing, using Greengenes 16S rRNA database for microbiota analysis. RESULTS: Among 96 hemodialysis (HD) patients, mean age was 61.9 ± 0.8 years and mean duration of HD was 6.5 ± 0.7 years. No significant differences were found in alpha diversity between HD and control groups (HD group 949.5, controls 898; p = 0.16) although significant between-group differences were found in beta diversity (p < 0.001). At phylum level, HD group had a higher abundance of Firmicutes and Proteobacteria, but lower abundance of Bacteriodetes. At genus level, Escherichia-Shigella complex increased among HD patients who had hospitalization with 1 year (median 0.024 vs 0.004, p = 0.054) and Klebsiella was associated with emergency room visit within 1 year among HD patients (p = 0.002). CONCLUSIONS: Alpha diversity in HD patients is not lower than that in healthy controls but significant between-group differences are found in microbiota composition according to beta diversity, due to decreased Bacteriodetes and increased Firmicutes and Proteobacteria. Deeper microbiota analyses for Enterobacteriaceae are necessary. Whether change in dietary components can help to decrease mortality among dialysis population warrants further research.

Cardiovascular and renal efficacy and safety of sodium-glucose cotransporter-2 inhibitors in patients without diabetes: a systematic review and meta-analysis of randomised placebo-controlled trials.

OBJECTIVES: To assess the cardiovascular and renal efficacy and safety of sodium-glucose cotransporter-2 (SGLT2) inhibitors in patients without diabetes. METHODS: We searched PubMed, MEDLINE, Embase and Cochrane Library for publications up to 17 August 2022. Certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation approach. Random-effects meta-analyses were performed to pool effect measures across studies. Risk ratios (RRs) with 95% CIs are expressed for composite cardiovascular outcome of cardiovascular death or hospitalisation for heart failure, cardiovascular death, hospitalisation for heart failure, all-cause mortality and composite renal outcome of ≥50% reduction in estimated glomerular filtration rate (eGFR), end-stage kidney disease or renal death. Annual rate of change in eGFR is expressed as the mean difference with 95% CI. RESULTS: We identified four trials with 8927 patients with heart failure or chronic kidney disease (CKD). Compared with placebo, SGLT2 inhibitors showed favourable effects on the composite cardiovascular outcome (RR: 0.79, 95% CI: 0.71 to 0.87; moderate certainty), cardiovascular death (0.85, 0.74 to 0.99; moderate certainty), hospitalisation for heart failure (0.72, 0.62 to 0.82; moderate certainty), the composite renal outcome (0.64, 0.48 to 0.85; low certainty) and the annual rate of change in eGFR (mean difference: 0.99, 0.59 to 1.39 mL/min/1.73 m2/year; moderate certainty), while there was no significant difference in all-cause mortality (0.88, 0.77 to 1.01; very low certainty). Moderate certainty evidence indicated that SGLT2 inhibitors reduced the risk of serious adverse events and acute renal failure. Low certainty evidence suggested that SGLT2 inhibitors increased the risk of urinary tract infection and genital infection, while there were no differences in discontinuation due to adverse events, amputation, fracture, hypoglycaemia, ketoacidosis or volume depletion. CONCLUSIONS: Evidence of low to moderate certainty suggests that SGLT2 inhibitors provide cardiorenal benefits but have increased risk for urinary tract infection and genital infection in patients without diabetes and with heart failure or CKD.

Humoral antibody response to the first dose of the ChAdOx1 nCoV-19 vaccine in Asian patients undergoing hemodialysis.

BACKGROUND AND OBJECTIVES: The immunogenicity of vaccines is known to be attenuated in patients with end-stage kidney disease due to uremia. Patients on dialysis were excluded from coronavirus disease 2019 (COVID-19) vaccine trials; thus, the effectiveness of vaccines for this population is unclear. The aim of this study was to explore whether Asian dialysis patients can effectively produce an immune response after being vaccinated with the first dose of the ChAdOx1 nCoV-19 vaccine. DESIGN SETTING, PARTICIPANTS, AND MEASUREMENTS: In this prospective cohort study, we included Asian hemodialysis patients who received the ChAdOx1 nCoV-19 vaccine. At 3 weeks after the first dose of vaccination, we assessed the humoral immune response by measuring anti-SARS-CoV-2 S antibody titers. The primary outcome was the seropositive rate following vaccination, defined as an antibody titer greater than or equal to 0.8 U/ml. Factors associated with seropositivity were explored in multivariate logistic regression analyses. RESULTS: In total, 434 participants were included. The mean age was 64 years, the mean dialysis vintage was 6 years, and 61% of the participants were men. At a mean time of 22 days from vaccination, 56% of the participants were seropositive. The vast majority (88%) had low antibody titers (< 15 U/ml). The multivariate logistic regression analyses showed that older age (every increase of 10 years, odds ratio [OR] 0.80, 95% CI 0.65-0.98, p = 0.03) was negatively associated with seropositivity and that higher Kt/V (every increase of 0.1, OR 1.14, 95% CI 1.01-1.28, p = 0.03) and higher serum albumin level (every increase of 0.1 g/dl, OR 1.09, 95% CI 1.02-1.18, p = 0.02) were positively associated with seropositivity. CONCLUSIONS: In Asian hemodialysis patients, the seropositive rate was low, and most had low antibody titers after the first dose of the ChAdOx1 nCoV-19 vaccine. Younger age, better dialysis adequacy, and higher albumin levels were associated with seropositivity.

Cardioprotective effects of dipeptidyl peptidase-4 inhibitors versus sulfonylureas in addition to metformin: A nationwide cohort study of patients with type 2 diabetes.

AIMS: Cardiovascular effects of dipeptidyl peptidase-4 inhibitors (DPP4i) versus sulfonylureas (SU) remain controversial in observational studies. This study aimed to evaluate the influence of DPP4i on major adverse cardiovascular events (MACEs), including acute myocardial infarction, cerebrovascular disease, heart failure, cardiogenic shock, malignant dysrhythmia, and revascularisation. MATERIALS AND METHODS: We conducted a nationwide cohort study using claims data from the National Health Insurance in Taiwan from 2007 to 2013. We enrolled type 2 diabetes patients who received DPP4i or SU in addition to metformin. DPP4i users were matched to SU users using propensity scores at a ratio of 1:1. The study outcomes were hospitalisation for MACE, heart failure, acute myocardial infarction, cerebrovascular disease, coronary revascularisation, and hypoglycaemia. RESULTS: There were 37,317 matched pairs of DPP4i and SU users with a mean follow-up of 2.1 years. Compared with SU users, DPP4i users showed a significantly lower risk of hospitalisation for MACE (HR 0.79 [95% CI 0.75-0.82]), heart failure (0.86 [0.79-0.93]), acute myocardial infarction (0.76 [0.68-0.92]), and cerebrovascular disease (0.72 [0.67-0.77]). Both sitagliptin (0.89 [0.85-0.94]) and vildagliptin ([0.77 [0.60-0.99]) showed a significantly lower risk of hospitalisation for MACE, but saxagliptin showed a borderline significantly higher risk of hospitalisation for heart failure (1.59 [1.00-2.55]). CONCLUSIONS: DPP4i showed better cardioprotective effects than SU, especially among patients receiving sitagliptin or vildagliptin.

Associations between urinary cysteine-rich protein 61 excretion and kidney function decline in outpatients with chronic kidney disease: a prospective cohort study in Taiwan.

OBJECTIVES: To examine whether urinary excretion of cysteine-rich protein 61 (Cyr61), an acknowledged proinflammatory factor in kidney pathologies, increases in chronic kidney disease (CKD) and is associated with subsequent rapid kidney function decline. DESIGN: An observational cohort study. SETTING: In the nephrology outpatient clinics of a tertiary hospital in Taiwan. PARTICIPANTS: We enrolled 138 adult CKD outpatients (n=12, 32, 18, 18, 29 and 29 in stages 1, 2, 3a, 3b, 4 and 5 CKD, respectively) between February and October 2014 and followed them for 1 year. Their mean age was 60.46±13.16 years, and 51 (37%) of them were women. PRIMARY OUTCOME MEASURES: Urinary Cyr61 levels were measured by ELISA. Rapid kidney function decline was defined as an estimated glomerular filtration rate (eGFR) decline rate ≥ 4 mL/min/1.73 m2/year or developing end-stage renal disease during subsequent 3-month or 1-year follow-up period. Models were adjusted for demographic and clinical variables. RESULTS: The urine Cyr61-to-creatinine ratio (UCyr61CR) increased significantly in patients with stage 4 or 5 CKD. Multivariable linear regression analysis showed that log(UCyr61CR) was positively correlated with log(urine protein-to-creatinine ratio) (p<0.001) but negatively correlated with baseline eGFR (p<0.001) and hypertension (p=0.007). Complete serum creatinine data during the follow-up were available for 112 patients (81.2%). Among them, multivariable logistic regression identified log(UCyr61CR) was independently associated with rapid kidney function decline (adjusted OR 2.29, 95% CI 1.27 to 4.15) during the subsequent 3 months. UCyr61CR improved the discriminative performance of clinical models to predict 3-month rapid kidney function decline. In contrast, log(UCyr61CR) was not associated with rapid eGFR decline during the entire 1-year follow-up. CONCLUSIONS: Elevated urinary Cyr61 excretion is associated with rapid short-term kidney function deterioration in patients with CKD. Measuring urinary Cyr61 excretion is clinically valuable for monitoring disease trajectory and may guide treatment planning.

The effectiveness of simulation education program on shared decision-making attitudes among nurses in Taiwan.

BACKGROUND: Shared decision-making (SDM) is significantly associated with promoting the quality of end-of-life (EOL). The attitude of nurses toward the end of life can affect EOL care, but there are few SDM-related clinical learning programs focused on EOL. In this study, therefore, we evaluated the effectiveness of an EOL-simulation education program on attitudes toward SDM among nurses, using an objective structured clinical examination (OSCE). METHODS: We used a quasi-experimental study design to evaluate nurses working at a medical center in Taiwan. We recruited 100 nurses and assigned them to an experimental group (n = 50) and a control group (n = 50). The experimental group received the SDM attitude (SDMA) cultivation program, and the control group did not. After the intervention, all participants were examined in an OSCE to assess the efficacy of their learning. A p value of.05 was considered statistically significant. RESULTS: The average score of the experimental group was higher than that of the control group in the dimensions "empathic communication" and "mastery learning", but these differences were not significant. SDMA score is significantly and positively correlated with SDMA global score, standardized patient survey (SPS) score, and SPS global score (r = .92, .56, and .50, respectively; p < .01). CONCLUSIONS: Simulations concerning EOL care that incorporate SDM components would be effective for training clinical nurses. This study can serve as a reference for nursing-administration managers who may consider designing SDM-related education programs to improve the quality of clinical nursing care.

Development and testing of the shared decision-making attitudes scale among nurses in Taiwan: a cross-sectional scale development study.

OBJECTIVE: Shared decision-making (SDM) enhances medical care, but an appropriate tool for evaluating nursing staff's attitudes towards SDM in clinical practice is lacking. The objective of this study is to develop the Nursing Shared Decision-Making Attitude (NSDMA) scale and verify its psychometric properties. DESIGN: Instrument design study. PARTICIPANTS: A sample of 451 nursing staff. INTERVENTION: This study comprised two phases. In phase 1, qualitative research and expert content validity were adopted to develop the first draft of the scale. In phase 2, Taiwanese nursing staff were recruited through convenience sampling, and the sample was divided into a calibration sample and a validation sample. An objective structured clinical examination of SDM attitudes was administered to 100 nursing staff to determine the scale's cut-off score. MAIN OUTCOME MEASUREMENTS: Exploratory factor analysis and confirmatory factor analysis were used to obtain the underlying factors of the NSDMA scale; McDonald's omega value was used to determine the reliability; known-group validity was used to test the construct validity; and the receiver operating characteristic curve was adopted to determine the scale's cut-off score. RESULTS: In total, two factors were identified from the instrument results, which were termed 'empathic communication' and 'mastery learning'. The McDonald's omega value of the overall scale was 0.92. Known-group validity testing was performed based on the staff's participation in SDM courses and experience of SDM, and the results exhibited significant differences (t=5.49, p<0.001; t=2.43, p<0.05). Based on the receiver operating characteristic curve, the optimal cut-off for SDM attitudes was determined as 48.5 points. CONCLUSIONS: The NSDMA scale enables the evaluation of SDM attitudes among clinical nursing staff and nursing managers; the results may serve as a reference for incorporation of SDM into nursing policy formulation.

Boiling for 15 minutes improves nutrient profiles in fishes included in the diets of dialysis patients.

INTRODUCTION: Little is known about the effects of boiling on nutrient levels in fishes that have a relatively high phosphorus-to-protein ratio (PPR), which are important sources of omega-3 polyunsaturated fatty acids. We hypothesized that the beneficial effects of boiling for a shorter duration (15 min) on nutrient contents in fishes were similar to those of boiling for a longer duration (30 min), which has been shown to decrease the PPR in meat. METHODS: The protein, fat, and phosphorus contents and the PPR of three cooked fish species and their corresponding fish broths were chemically analyzed. The effects of boiling on changes in protein, fat, phosphorus, and the PPR was examined by comparing fish that were prepared with usual cooking methods (no boiling), boiled for 15 min, and boiled for 30 min. The nutrients in fish broths that were boiled for 15 min were also compared with those boiled for 30 min. FINDINGS: There were no significant differences in the changes in phosphorus, PPR, protein, and fat content in fish and fish broths prepared with the two boiling methods. In the fish boiled for 15 min, the phosphorus content was 24% lower (p = 0.001), and the PPR was 20% lower (p = 0.04) than those in nonboiled fish. Additionally, boiling for 30 min reduced the phosphorus content by 31% (p = 0.001), and the PPR by 27% (p = 0.04) compared to nonboiled fish, but the protein and fat contents were unchanged after both 15 and 30 min of boiling. DISCUSSION: The 15- and 30-min boiling methods resulted in a similar reduction in phosphorus and the PPR in fish, with minimal effects on protein and fat. A shorter duration of boiling is recommended to achieve better nutrient profiles in fishes consumed by dialysis patients.

Shared clinical decision-making experiences in nursing: a qualitative study.

BACKGROUND: Shared decision making (SDM) is a patient-centered nursing concept that emphasizes the autonomy of patients. SDM is a co-operative process that involves information exchange and communication between medical staff and patients for making treatment decisions. In this study, we explored the experiences of clinical nursing staff participating in SDM. METHODS: This study adopted a qualitative research design. Semistructured interviews were conducted with 21 nurses at a medical center in northern Taiwan. All interview recordings were transcribed verbatim. Content analysis was performed to analyze the data. RESULTS: The findings yielded the following three themes covering seven categories: knowledge regarding SDM, trigger discussion and coordination, and respect of sociocultural factors. CONCLUSIONS: The results of this study describe the experiences of clinical nursing staff participating in SDM and can be used as a reference for nursing education and nursing administrative supervisors wishing to plan and enhance professional nursing SDM in nursing education.
