PurposeTo determine whether green banana powder (GBP) and pineapple fibre powder (PFP) promote beneficial bacterial species, directly improve human gut health and modulate the gut microbiome and understand their utility as functional foods and dietary supplements.MethodsOver 14 days, 60 adults followed protocol requirements, completed food diaries and study questionnaires, avoided consuming supplements with prebiotics, probiotics or postbiotics, and ingested food containing 5 g of total daily fibre [placebo (10.75 g), GBP (10.75 g) or PFP (7.41 g)]. Participants’ medical and baseline wellness histories, as well as stool samples, were collected at baseline, day 7 and 14. Stool DNA was processed for sequencing.ResultsDietary fibre and resistant starches (RS) in GBP and PFP promoted temporal increases in beneficial bacteria. GBP significantly elevated 7 species (F. prausnitzii, B. longum, B. bifidum, B. adolescentis, B. pseudocatenulatum, B. obeum, and R. inulinivorans), while PFP enriched 6 species (B. ovatus, B. cellulosilyticus, B. bifidum, B. intestinalis, R. inulinivorans, and E. siraeum). These bacteria, found to be deficient in younger adults, were promoted by both powders. PFP benefitted both genders aged 16–23, while GBP benefitted overweight/obese individuals, including females. GBP and PFP fiber and RS improved bowel regularity and health as well as metabolism by promoting histidine, branched-chain amino acids, short-chain fatty acids, and biotin production. The additional fiber caused “low” bloatedness and reduced “fairly bad” sleep disruptions, without affecting sleep durations.ConclusionGBP and PFP supplementation increased beneficial bacteria and metabolites, improved host gut health, and present a valuable nutritional strategy for enhancing human health.Clinical trial registrationAMILI Institutional Review Board, Identifier 2023/0301.

Background Remote patient monitoring (RPM) for automated peritoneal dialysis (APD) may improve clinical outcomes. Paediatric data, however, remain extremely scarce. Methods We conducted a prospective observational study of children (0-18 years) receiving APD with cloud-based RPM over two 24-week periods (pre- and post-RPM). Primary outcomes were unplanned hospitalizations and fluid management. Children receiving APD without RPM (non-RPM) were included as control. Results Seven patients (6 females) receiving APD were enrolled in the RPM programme at 11.3 years (IQR 2.6-17.1). Main indications for RPM included history of fluid overload (n = 3) and non-adherence (n = 2). Ten children were included in the non-RPM group (6 females; 16.9 years, IQR 12.8-17.6). Four patients (57.1%, 95% CI 22.5-100%) experienced fewer unplanned hospitalizations and 5 patients (71.4%, 95% CI 34.1-100%) had shorter hospital stays during the post-RPM period. The hospitalization rates and length of stay were reduced by 45% and 42%, respectively. The higher hospitalization rates among the RPM group, compared to the non-RPM group, were no longer observed following implementation of RPM. There was a significant increase in ultrafiltration (565.6 ± 248.7 vs. 501.7 ± 286.6 ml/day, p = 0.03) and reduction in systolic blood pressure (114.1 ± 12.6 vs. 119.9 ± 11.19 mmHg, p = 0.02) during the post-RPM period. All patients demonstrated satisfactory adherence. Although quality of life (PedsQL 3.0 ESRD module) was not different pre- and post-RPM, all patients agreed in the questionnaires that the use of RPM improved their quality of life and sense of security. Conclusions In conclusion, RPM in children receiving APD is associated with fewer and shorter unplanned hospitalizations, improved fluid management and favourable adherence to PD.

Abstract Background Vaspin is an adipokine that regulates glucose and lipid metabolism. Plasma vaspin level is increased in chronic kidney disease but decreased in hemodialysis patients. However, plasma vaspin level in peritoneal dialysis (PD) patients, as well as its prognostic role, has not been studied. Methods We recruited 146 incident PD patients. Their baseline plasma vaspin levels, body anthropometry, the profile of insulin resistance, bioimpedance spectroscopy parameters, dialysis adequacy, and nutritional indices were measured. They were followed for up to 5 years for survival analysis. Results The average age was 58.4 ± 11.8 years; 96 patients (65.8%) were men, and 90 (61.6%) had diabetes. The median vaspin level was 0.18 ng/dL (interquartile range [IQR] 0.11 to 0.30 ng/dL). Plasma vaspin level did not have a significant correlation with adipose tissue mass or baseline insulin level. However, plasma vaspin level had a modest correlation with the change in insulin resistance, as represented by the HOMA-IR index, in non-diabetic patients (r = -0.358, p = 0.048). Although the plasma vaspin level quartile did not have a significant association with patient survival in the entire cohort, it had a significant interaction with diabetic status (p

ABSTRACTBackground HELLP syndrome, featuring hemolysis, elevated liver enzymes, and thrombocytopenia, is life-threatening disease of pregnancy that triggers comorbidities in both pregnant women and the fetus/newborn. This study provides an updated systematic review and meta-analysis of relevant studies to assess the therapeutic efficacy of corticosteroids in maternal and neonatal outcomes.Methods Randomized control trials (RCTs) regarding the use of corticosteroids in the HELLP population from three electronic databases, including Ovid MEDLINE, Ovid EMBASE, andCochrane Central Register of Controlled Trials, were searched from database inception to 23 March 202323 March 2023.Results A total of 485 patients treated with corticosteroids from 7 RCTs were included. Compared to placebo, corticosteroids therapy failed to significantly improve the maternal outcomes regard to maternal morbidity (RR = 1.36, 95%CI [0.45, 4.10]), eclampsia (RR = 1.16, 95%CI [0.76, 1.77]), acute renal failure (RR = 0.71, 95%CI [0.41, 1.22]), pulmonary edema (RR = 0.34, 95%CI [0.10, 1.15]) and oliguria (RR = 1.08, 95%CI [0.75, 1.54]). In addition, pooled data showed that it wasn’t significant differences between corticosteroids therapy and placebo regarding neonatal outcomes.Conclusions This study compared the efficacy of corticosteroids in patients with HELLP syndrome, revealing that corticosteroids did not provide any significant benefit in clinical outcomes for pregnant women and newborns with HELLP. The conclusions of this study must be verified by a larger sample of high-quality RCTs.

Background: Performance goal orientations are influential motivational factors for predicting learning performance. However, a lack of attention has been paid to investigating the effects of performance goal orientations on learning performance and in-game performance in the context of digital game-based learning. Objectives: This study implemented a game-based English vocabulary learning system and investigated how performance goal orientations affected learners' learning performance and in-game performance. Methods: A total of 59 non-English major university students participated in this study, divided into performance-approach learners (PAPL) and performance-avoidance learners (PAVL) based on their performance goal orientations. The English vocabulary listening test and log data were collected for conducting quantitative analyses. Results and conclusions: The results showed that the PAPL outperformed the PAVL in learning performance, whereas the two groups demonstrated similar gain scores and overall in-game performance. Moreover, the results showed that the PAVL's learning performance was strongly associated with all aspects of in-game performance in the learning activities. Conversely, the PAPL's learning performance was only associated with two aspects of in-game performance in the competition activities. Implications: The findings of this study suggest that performance goal orientations play significant roles in both learning performance and in-game performance, which could benefit the PAVL's in-game performance, which is a substantial factor in promoting their learning performance via DGBL.

Rationale & Objective: The efficacy and safety profile of apixaban remains uncertain in patients receiving peritoneal dialysis (PD) despite increasing use in this population. Accordingly, we assessed the pharmacokinetics of apixaban among patients receiving PD. Study Design: A pharmacokinetics study in a single center. Patients recruited received 1 week of apixaban at 2.5 mg twice a day to reach steady state. Serial blood samples were then taken before and after the last dose for pharmacokinetics analysis of apixaban. Setting & Participants: Ten stable PD patients with atrial fibrillation in an outpatient setting. Analytical Approach/Outcomes: Pharmacokinetic parameters including the area under the concentration-time curve from time 0 to 12 hours after the last dose of apixaban (AUC0-12), peak concentration, trough level, time to peak apixaban concentration, half-life, and drug clearance were analyzed. Results: There was a wide variation in the range of apixaban concentration across the 10 patients. The AUC0-12 for the PD group was significantly higher than those reported previously for hemodialysis patients or healthy individuals. Three patients had a supratherapeutic peak concentration whereas 2 patients had a supratherapeutic trough level as compared with the pharmacokinetic parameter in healthy individuals taking equivalent therapeutic dosage. Limitations: Small sample size with short study duration limits the ability to ascertain the true bleeding risk and to detect any clinical outcomes. Results may be limited to Asian populations only. Conclusions: A proportion of PD patients had supratherapeutic levels even when the reduced dosage 2.5 mg twice a day was used. Given the large interindividual variation in the drug level, therapeutic drug monitoring should be done if available. Otherwise, one should start the drug at reduced doses with caution and with more frequent clinical monitoring for any signs of bleeding.

ObjectiveIncreasing evidence suggests that gut microbiota is involved in the occurrence and progression of urinary system diseases such as clear cell renal cell carcinoma (ccRCC). However, the mechanism of how alteration of gut metagenome promotes ccRCC remains unclear. Here we aim to elucidate the association of specific gut bacteria and their metabolites with ccRCC.MethodsIn a pilot case-control study among 30 ccRCC patients (RCC group) and 30 healthy controls (Control group), 16S ribosomal RNA (rRNA) gene sequencing were analyzed from fecal samples collected prior to surgery or hospitalization. Alpha diversity and beta diversity analysis of the gut microbiota were performed, and differential taxa were identified by multivariate statistics. Meanwhile, serum metabolism was measured by UHPLC-MS, and differential genes were identified based on the TCGA database.ResultsAlpha diversity found there were no significant microbial diversity differences of gut microbiota between the RCC group and the Control group. However, beta diversity analysis showed that the overall structures of the two groups were significantly separated (p = 0.008). Random Forests revealed the relative abundances of 20 species differed significantly between the RCC group and the Control group, among which nine species were enriched in the RCC group such as Desulfovibrionaceae, and 11 species were less abundant such as four kinds of Lactobacillus. Concomitantly, serum level of taurine, which was considered to be consumed by Desulfovibrionaceae and released by Lactobacillus, has decreased in the RCC group. In addition, macrophage-related genes such as Gabbr1 was upregulated in ccRCC patients.ConclusionReduction of protective bacteria, proliferation of sulfide-degrading bacteria Desulfovibrionaceae, reduction of taurine, and enrichment of macrophage related genes might be the risk predictors of ccRCC.

Rationale & Objective: Omentin-1 is an adipokine with anti-inflammatory and cardioprotective properties. The objective of this study was to determine the prognostic role of plasma omentin-1 levels in incident peritoneal dialysis (PD) patients. Study Design: Retrospective analysis of prospective cohort. Setting & Participants: 152 incident PD patients. Predictors: Plasma omentin-1 level, adipose tissue omentin-1 messenger RNA (mRNA) expression. Outcomes: Patient survival, technique survival, hospital admission, and duration of stay. Analytical Approach: Time-to-event survival analyses; linear regression for hospitalization. Results: The mean age was 58.4 ± 11.7 years; 102 were men, and 92 had diabetes. There was no significant correlation between plasma omentin-1 level and its adipose tissue mRNA expression. A higher plasma omentin-1 level quartile was not associated with patient survival (P = 0.92) or technique survival (P = 0.83) but had a modest correlation with a lower number of hospital admissions (P = 0.07) and shorter duration of hospital stay (P = 0.04). In adjusted models using multivariable linear regression, a higher plasma omentin-1 level quartile remained significantly associated with fewer hospital admissions (β, -0.13; 95% CI, -0.26 to -0.002; P = 0.05) and shorter hospitalization duration (β, -0.20; 95% CI, -0.38 to -0.02; P = 0.03). Limitations: Observational study with baseline measures only. Conclusions: Plasma omentin-1 level was not associated with patient survival, technique survival, or peritonitis, but higher plasma omentin-1 levels were associated with fewer hospital admissions and shorter duration of hospitalization among incident PD patients.

Rationale & Objective: Cardiovascular disease is the major cause of mortality and morbidity in peritoneal dialysis (PD) patients. Adiponectin, a key adipokine, is related to obesity and insulin resistance. We determined the clinical and prognostic value of plasma adiponectin level and its adipose tissue messenger RNA (mRNA) expression in new PD patients. Study Design: Retrospective analysis of a prospective observational study. Setting & Participants: 152 new PD patients from a single center; 6 adults undergoing abdominal surgeries without kidney disease served as controls. Predictors: Plasma adiponectin level and its adipose tissue mRNA expression. Outcomes: Body build and composition, patient and technique survival. Analytical Approach: Adiponectin level and mRNA expression were grouped in quartiles for correlation analysis for body build and Cox regression for survival analysis. Results: The median plasma adiponectin level was 31.98 μg/mL (IQR, 16.81-49.49 μg/mL), and adiponectin mRNA expression in adipose tissue was 1.65 times higher than in controls (IQR, 0.98-2.63). There was a modest but statistically significant correlation between plasma adiponectin and its adipose tissue mRNA expression (r = 0.40, P

Abstract There were limited data on adipose and serum zinc alpha-2-glycoprotein (ZAG) expression and its association with body composition in patients with advanced chronic kidney disease (CKD). This study aimed to quantify adipose and serum ZAG expression and evaluate their association with body composition and its longitudinal change, together with mortality in incident dialysis patients. We performed a single-center prospective cohort study. Patients who were planned for peritoneal dialysis were recruited. ZAG levels were measured from serum sample, subcutaneous and pre-peritoneal fat tissue obtained during peritoneal dialysis catheter insertion. Body composition and functional state were evaluated by bioimpedance spectroscopy and Clinical Frailty Scale respectively at baseline and were repeated 1 year later. Primary outcome was 2-year survival. Secondary outcomes were longitudinal changes of body composition. At baseline, the average adipose and serum ZAG expression was 13.4 ± 130.0-fold and 74.7 ± 20.9 µg/ml respectively. Both adipose and serum ZAG expressions independently predicted adipose tissue mass (ATM) (p = 0.001, p = 0.008, respectively). At 1 year, ATM increased by 3.3 ± 7.4 kg (p
