Abstract
OBJECTIVE Failure-to-mature and early stenosis remains the Achille's heel of hemodialysis arteriovenous fistula (AVF) creation. The maturation and patency of an AVF can be influenced by a variety of demographic, comorbidity, and anatomical factors. This study aims to review the prediction models of AVF maturation and patency with various risk scores and machine learning models. DATA SOURCES AND REVIEW METHODS Literature search was performed on PubMed, Scopus, and Embase to identify eligible articles. The quality of the studies was assessed using the Prediction model Risk Of Bias ASsessment (PROBAST) Tool. The performance (discrimination and calibration) of the included studies were extracted. RESULTS Fourteen studies (seven studies used risk score approaches; seven studies used machine learning approaches) were included in the review. Among them, 12 studies were rated as high or unclear "risk of bias." Six studies were rated as high concern or unclear for "applicability." C-statistics (Model discrimination metric) was reported in five studies using risk score approach (0.70-0.886) and three utilized machine learning methods (0.80-0.85). Model calibration was reported in three studies. Failure-to-mature risk score developed by one of the studies has been externally validated in three different patient populations, however the model discrimination degraded significantly (C-statistics: 0.519-0.53). CONCLUSION The performance of existing predictive models for AVF maturation/patency is underreported. They showed satisfactory performance in their own study population. However, there was high risk of bias in methodology used to build some of the models. The reviewed models also lack external validation or had reduced performance in external cohort.

Abstract
Objective To identify facilitators to routine medical checkups (RMCs) use among Saudi adults from the perspectives of primary care providers (PCPs). Methods A qualitative phenomenological study design was conducted at five primary health care centers (PHCs) in Makkah, Saudi Arabia. Data was collected between December 2020 and February 2021 using semi-structured interviews with 19 PCPs. Descriptive statistics were performed to characterize participants, and a direct content analysis was conducted to identify major themes. Results A number of factors were identified as facilitators for RMCs use among Saudi adults. Those facilitators were classified into three main themes related to patients, providers, and healthcare systems. Patients' knowledge about the importance of RMCs and their awareness of the service availability were identified as key facilitators under patients-related theme. Providers' knowledge, skills, and awareness of RMCs were identified as facilitators under provider-related themes. Lastly, improving the supply of providers and enhancing access were the facilitators identified under the healthcare system-related theme. Conclusion This study provided insights into the facilitators for RMCs use among Saudi adults from the perspective of PCPs. This could contribute to the knowledge and inform future research, policy, and decision-making related to increasing the use of RMCs among Saudis.

Prevalence of and factors associated with chronic kidney disease among patients infected with human immunodeficiency virus attending care and treatment centers at tertiary hospitals in dodoma, Tanzania. Heliyon 2024; 10:e32994. [PMID: 38988569 PMCID: PMC11234037 DOI: 10.1016/j.heliyon.2024.e32994] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 05/01/2024] [Accepted: 06/12/2024] [Indexed: 07/12/2024] Open
Abstract
Background The burden and risk of developing chronic kidney disease (CKD) among patients with Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) is higher than in the general population. This study aimed to determine prevalence of and associated factors with CKD among adults infected with human immunodeficiency virus at tertiary hospitals in Dodoma, Tanzania. Method ology: A cross-sectional study was carried out between November 2022 to April 2023. Patients' demographic data, and clinical measurements were obtained on the day of the visit. Laboratory investigations were performed as standard of care. Descriptive and inferential analyses were performed, and variables associated with CKD were identified by multivariable logistic regression. Results A total of 223 patients were enrolled, with a median age of 47 (IQR 38-56) years, and 72.2 % were female. The CKD prevalence was 23.3 % whereby 18.4 % had CKD stage 3a, 4.5 % had CKD stage 3 b, and 0.4 % had CKD stage 4. CKD was observed largely among patients with obesity (34.15 %), anemia (29.41 %), hypertension (45.00 %), and diabetes mellitus (50.00 %). Variables with higher odds for CKD after adjusted analysis were hypertension (OR 3.03, 95 %% CI 1.29-7.11, P = 0.0109), diabetes mellitus (OR 4.50, 95 % CI 1.35-15.03, P = 0.0144), obesity (OR 3.07, 95 % CI 1.11-8.47, P = 0.0301), anaemia (OR 2.42, 95 % CI 1.12-5.26, P = 0.0252) and for each one-unit increase in age (years), there was statistically significant increase in the odds of having CKD by 1.084 folds (OR = 1.084, 95 % CI 1.039-1.131, p = 0.0002). Conclusion The prevalence of CKD among patients with HIV/AIDS is high. Age, obesity, anaemia, hypertension, and diabetes mellitus were strongly associated with CKD suggesting a need for integrating initiatives for non-communicable disease control in this population.

Abstract
This study proposes a novel robust optimization approach for an integrated water supply system, wherein the decision-makers attempt to improve failure safety of system under various uncertainty strategies. To cope with uncertainty, the ellipsoid uncertainty set is assumed to evaluate the best feasible solution in the direction of water supply under various strategies. We assessed the case of Hamoun watershed, a water-stressed watershed in southeastern of Iran, to evaluate the developed robust optimization model. In the following, the comparative feasibility under uncertainty levels is conducted to analyze the impacts of simulation strategies on the status of robust model. Based on the final results, the reliability of the model's objective functions experienced an increasing trend ( 58.3 % ), and the objective function values under the uncertainty strategies is greatly improved. The findings of the analysis show that the robust strategies in response to the failure safety achieve outstanding optimal objectives under uncertainty.

Abstract
Dynamic functional connectivity, derived from resting-state functional magnetic resonance imaging (rs-fMRI), has emerged as a crucial instrument for investigating and supporting the diagnosis of neurological disorders. However, prevalent features of dynamic functional connectivity predominantly capture either temporal or spatial properties, such as mean and global efficiency, neglecting the significant information embedded in the fusion of spatial and temporal attributes. In addition, dynamic functional connectivity suffers from the problem of temporal mismatch, i.e., the functional connectivity of different subjects at the same time point cannot be matched. To address these problems, this article introduces a novel feature extraction framework grounded in two-directional two-dimensional principal component analysis. This framework is designed to extract features that integrate both spatial and temporal properties of dynamic functional connectivity. Additionally, we propose to use Fourier transform to extract temporal-invariance properties contained in dynamic functional connectivity. Experimental findings underscore the superior performance of features extracted by this framework in classification experiments compared to features capturing individual properties.

Abstract
Creatinine is an important biomarker for the diagnosis of chronic kidney disease (CKD). Recently, it has been reported that the concentration of salivary creatinine correlates well with the concentration of serum creatinine, which makes the former useful for the development of non-invasive and point-of-care (POC) detection for CKD diagnosis. However, there exists a technical challenge in the rapid detection of salivary creatinine at low concentrations of 3-18 μM when using the current kidney function test strips as well as the traditional methods employed in hospitals. Herein, we demonstrate a simple, sensitive colorimetric assay for the detection of creatinine with a limit-of-detection (LOD) down to the nanomolar level. Our approach utilises the dual binding affinity of creatinine for citrate-capped silver nanoparticles (Ag NPs) and Ag(i) ions, which can trigger the aggregation of Ag NPs and thus lead to the colour change of a sample. The quantitative detection of creatinine was achieved using UV-Vis spectroscopy with a LOD of 6.9 nM in artificial saliva and a linear dynamic range of 0.01-0.06 μM. This method holds promise to be further developed into a POC platform for the CKD diagnosis.

Abstract
Background There is controversy in relation to commonly used drugs in heart failure (HF) and their impact on muscle function. The aim of this study was to evaluate the odds of receiving specific medications often used in clinical practice by patients with HF and sarcopenia vs. without sarcopenia. Methods A systematic literature search of cohort studies via databases (PubMed, Web of Science, Scopus, and Cochrane Library) was conducted from inception until March 2023. To determine if sarcopenia is linked to a higher number of specific HF-related medications, a meta-analysis using a random-effects model was used to calculate the pooled effects. Results Our main analyses showed no significant association of sarcopenia with administration of higher HF-related medication count vs. those without sarcopenia. Those with lower appendicular lean mass (ALM) had significantly lower odds of receiving angiotensin converting enzyme inhibitors (ACE-Is)/angiotensin receptor blockers (ARBs) (OR: 0.68, 95%CI 0.50-0.90, I2 = 12%, P < 0.01) vs. patients with higher ALM for which age could be an important confounder based on meta-regression. No statistically significant differences were found in relation to B-blockers OR: 0.84, 95%CI 0.63-1.12, I2 = 7%, P = 0.24) and loop diuretics (OR: 1.19, 95%CI 0.87-1.63, I2 = 0%, P = 0.27). Regarding handgrip strength, gait speed, and short physical performance battery, our narrative synthesis found mixed results. Conclusion This systematic review and meta-analysis did not find a relationship of specific medication count in sarcopenia vs. without sarcopenia in patients with HF, although increased odds of ACE-I/ARB was shown in those with higher ALM. Systematic Review Registration PROSPERO (CRD42023411137).

Abstract
The gut microbiome plays a critical role in the pathogenesis of type 2 diabetes mellitus (T2DM). However, the inconvenience of obtaining fecal samples hinders the clinical application of gut microbiome analysis. In this study, we hypothesized that tongue coating color is associated with the severity of T2DM. Therefore, we aimed to compare tongue coating, gut microbiomes, and various clinical parameters between patients with T2DM with yellow (YC) and non-yellow tongue coatings (NYC). Tongue coating and gut microbiomes of 27 patients with T2DM (13 with YC and 14 with NYC) were analyzed using 16S rDNA gene sequencing technology. Additionally, we measured glycated hemoglobin (HbA1c), random blood glucose (RBG), fasting blood glucose (FBG), postprandial blood glucose (PBG), insulin (INS), glucagon (GC), body mass index (BMI), and homeostasis model assessment of β-cell function (HOMA-β) levels for each patient. The correlation between tongue coating and the gut microbiomes was also analyzed. Our findings provide evidence that the levels of Lactobacillus spp. are significantly higher in both the tongue coating and the gut microbiomes of patients with YC. Additionally, we observed that elevated INS and GC levels, along with decreased BMI and HOMA-β levels, were indicative of a more severe condition in patients with T2DM with YC. Moreover, our results suggest that the composition of the tongue coating may reflect the presence of Lactobacillus spp. in the gut. These results provide insights regarding the potential relationship between tongue coating color, the gut microbiome, and T2DM.

Abstract
Thrombotic microangiopathy (TMA) is a rare but serious side effect of tyrosine kinase inhibitor (TKI) therapy. Previous case reports of renal TMA have usually occurred in the first few months of TKI initiation with only very few cases occurring within 2-3 years. We report a case of a patient who was referred to the Nephrology service for nephrotic syndrome and worsening renal function after 8 years of sunitinib therapy for metastatic clear cell carcinoma of the kidney. Renal biopsy showed chronic TMA without another secondary aetiology identified. With discontinuation of sunitinib and pharmacological optimisation of his hypertension, his renal function and proteinuria both significantly improved. No relapse or recurrence of disease activity was noted after a year of follow-up. This case highlights the importance of remaining vigilant for the development of renal TMA even after an extended duration of TKI therapy.

Abstract
Objectives Rhabdomyolysis leads to the release of myoglobin, sarcoplasmic proteins, and electrolytes into the blood circulation causing acute kidney injury (AKI). Thymoquinone, a natural compound found in Nigella sativa seeds, has antioxidant and anti-inflammatory effects. This investigation assessed the renoprotective effect of thymoquinone on rhabdomyolysis-induced AKI in rats. Materials and Methods Male Wistar rats were categorized into six groups (n = 6): 1. Control: (normal saline), 2. Glycerol (50 ml/kg, single dose, IM), 3-5: Glycerol + thymoquinone (1, 2.5 and 5 mg/kg, 4 days, IP), 6. Thymoquinone (5 mg/kg). On day 5, serum and kidney tissue were isolated and the amounts of serum creatinine and blood urea nitrogen (BUN), renal malondialdehyde (MDA), glutathione (GSH.), tumor necrosis factor-alpha (TNF-α), neutrophil gelatinase-associated lipocalin (NGAL), and pathological changes were evaluated. Results Glycerol increased creatinine, BUN, MDA, TNF-α, and NGAL levels. It decreased GSH amounts and caused renal tubular necrosis, glomerular atrophy, and myoglobin cast in kidney tissue. Co-administration of glycerol and thymoquinone reduced creatinine, BUN, histopathological alterations, and MDA levels, and enhanced GSH amounts. Administration of glycerol and thymoquinone (5 mg/kg) had no significant effect on TNF-α amount but decreased NGAL protein levels. The administration of thymoquinone (5 mg/kg) alone did not display a significant difference from the control group. Conclusion Rhabdomyolysis from glycerol injection in rats can cause kidney damage. Thymoquinone may attenuate renal dysfunction and oxidative stress. However, the TNF-α level was not significantly affected. Further studies are needed to explore the potential therapeutic effects of thymoquinone in managing AKI.

Abstract
Background Non-adherence to treatments increases the rates of hemodialysis complications, hospitalization, and mortality. One strategy for adherence improvement is peer education. This study aimed to investigate the effects of peer education on treatment adherence among patients receiving hemodialysis. Materials and Methods This was a randomized controlled trial. Patients in the control group were provided just with routine care, and the intervention group received peer education. Treatment adherence was assessed both before and after the intervention via the End-Stage Renal Disease (ESRD) Adherence Questionnaire. Data analysis was conducted by the Chi-square, the Mann-Whitney U, the paired-sample t, and the independent-sample t tests. Results There were no significant between-group differences in terms of the pre-test mean scores of Adherence to regular attendance at hemodialysis sessions (t = 0.19, p = 0.85), Adherence to the prescribed medications (t = 0.46, p = 0.64), and Adherence to fluid restrictions (t = 0.24, p = 0.81). The same finding was observed after the intervention, except for the mean score of the adherence to fluid restrictions dimension which was significantly greater in the intervention group (t = 2.86, p = 0.006). Moreover, no significant changes were observed in the mean scores of treatment adherence dimensions in the control group. However, in the intervention group, the mean scores of the adherence to regular attendance at hemodialysis sessions (t = 3.79, p < 0.001) and the adherence to fluid restrictions dimensions were significantly greater than their pre-test values (t = 4.47, p < 0.001). Conclusions Education by peer groups improves the compliance of patients with regard to the consumption of fluids in the interval between two dialysis sessions.

Abstract
BACKGROUND Chronic kidney disease (CKD) is a prevalent and progressive disease that is impacted by hyperglycemia, hypertension (HTN), and oxidative stress (OS). Propolis, a natural resinous mixture produced by honeybees from plant materials, has been shown to possess antioxidant, anti-inflammatory, antihyperglycemic, and antihypertensive properties, along with hepato-renal protective effects. This study aims to evaluate the efficacy of propolis supplementation on patients with CKD. METHODS This multi-centered, randomized, double-blind, placebo-controlled clinical trial will evaluate the effectiveness of propolis supplementation in 44 eligible patients with CKD. Participants will be randomly allocated to receive either propolis capsule (500 mg, containing 125 mg Iranian alcoholic propolis extract) or placebo, twice daily for three months. The primary outcome is improvement in kidney function parameters of CKD patients, while secondary outcomes include changes in prooxidant-antioxidant balance (PAB), glycemic status, quality of life, and blood pressure (BP). The study will be conducted at Tabriz University of Medical Sciences in Tabriz, Iran. DISCUSSION If the results of this study reveal remarkable effectiveness of propolis in improving quality of life and clinical outcomes in patients with CKD, this compound may reach a new milestone as an adjunctive therapy for CKD and it opens a new window for further studies.

Abstract
Alport syndrome (AS) is a hereditary progressive glomerular disease associated with sensorineural hearing loss and ocular abnormalities. It is attributed to the altered structure and the subsequent dysfunction of the glomerular basement membrane (GBM) due to the mutated type IV collagen a3/a4/a5 chains. It may emerge either as an X-linked disease, the most common, or as an autosomal disease, both recessive and dominant. A female patient, 26 years old, came in 2023 to the Department of Oral Medicine/ Pathology, Dental School, Aristotle University of Thessaloniki, complaining about pain and a burning sensation in her right cheek. Her medical history revealed the diagnosis of Alport syndrome in 2016 and kidney transplantation in 2022 with extensive post-transplantation drug administration. The clinical examination revealed an ulcer, partially covered by a pseudomembrane, on the oral mucosa of the right cheek, surrounded by an erythematous border. A biopsy was taken, and the histopathological examination showed the oral manifestation of mucous membrane pemphigoid. After communicating with the attending nephrologist, the prescription of methylprednisolone was decided, and the lesions receded. The differential diagnosis included both AS-induced pemphigoid and drug-induced pemphigoid. The thorough medical history, detailed clinical investigation, lesion biopsy, and collaboration of different dental and medical specialties constitute necessary prerequisites for a successful treatment, even in immunosuppressed patients.

Abstract
BACKGROUND Epidemics of chronic kidney disease of undetermined causes (CKDu) among young male agricultural workers have been observed in many tropical regions. Western Kenya has similar climatic and occupational characteristics as many of those areas. The study objectives were to characterize prevalence and predictors of CKDu, such as, HIV, a known cause of CKD, in a sugarcane growing region of Kenya; and to estimate prevalence of CKDu across occupational categories and evaluate if physically demanding work or sugarcane work are associated with reduced eGFR. METHODS The Disadvantaged Populations eGFR Epidemiology Study (DEGREE) protocol was followed in a cross-sectional study conducted in Kisumu County, Western Kenya. Multivariate logistic regression was performed to identify predictors of reduced eGFR. RESULTS Among 782 adults the prevalence of eGFR < 90 was 9.85%. Among the 612 participants without diabetes, hypertension, and heavy proteinuria the prevalence of eGFR < 90 was 8.99% (95%CI 6.8%, 11.5%) and 0.33% (95%CI 0.04%, 1.2%) had eGFR < 60. Among the 508 participants without known risk factors for reduced eGFR (including HIV), the prevalence of eGFR < 90 was 5.12% (95%CI 3.4%, 7.4%); none had eGFR < 60. Significant risk factors for reduced eGFR were sublocation, age, body mass index, and HIV. No association was found between reduced eGFR and work in the sugarcane industry, as a cane cutter, or in physically demanding occupations. CONCLUSION CKDu is not a common public health problem in this population, and possibly this region. We recommend that future studies should consider HIV to be a known cause of reduced eGFR. Factors other than equatorial climate and work in agriculture may be important determinants of CKDu epidemics.

Abstract
INTRODUCTION Women with Chronic Kidney Disease (CKD) are at increased risk of adverse pregnancy and renal outcomes. It is unknown how women with CKD understand their pregnancy risk. This nine-centre, cross-sectional study aimed to explore how women with CKD perceive their pregnancy risk and its impact on pregnancy intention, and identify associations between biopsychosocial factors and perception of pregnancy risk and intention. METHODS Women with CKD in the UK completed an online survey measuring their pregnancy preferences; perceived CKD severity; perception of pregnancy risk; pregnancy intention; distress; social support; illness perceptions and quality of life. Clinical data were extracted from local databases. Multivariable regression analyses were performed. Trial registration: NCT04370769. RESULTS Three hundred fifteen women participated, with a median estimated glomerular filtration rate (eGFR) of 64 ml/min/1.73m2 (IQR 56). Pregnancy was important or very important in 234 (74%) women. Only 108 (34%) had attended pre-pregnancy counselling. After adjustment, there was no association between clinical characteristics and women's perceived pregnancy risk nor pregnancy intention. Women's perceived severity of their CKD and attending pre-pregnancy counselling were independent predictors of perceived pregnancy risk. Importance of pregnancy was an independent predictor of pregnancy intention but there was no correlation between perceived pregnancy risk and pregnancy intention (r = - 0.002, 95% CI - 0.12 to 0.11). DISCUSSION Known clinical predictors of pregnancy risk for women with CKD were not associated with women's perceived pregnancy risk nor pregnancy intention. Importance of pregnancy in women with CKD is high, and influences pregnancy intention, whereas perception of pregnancy risk does not.

Front Pediatr 2023; 10:1078853. [PMID: 36819194 PMCID: PMC9932899 DOI: 10.3389/fped.2022.1078853] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Accepted: 12/19/2022] [Indexed: 02/05/2023] Open
Abstract
Background Mineral bone disorders (MBD) are common in sickle cell anemia (SCA). Frequent vaso-occlusive crises (VOC) further impact MBD in children with SCA. We evaluated the prevalence of markers of SCA-related MBD (sMBD) in hospitalized children and assessed the relationship between sMBD and individual mineral abnormalities with kidney disease. Methods We prospectively recruited 185 children with SCA hospitalized with a VOC. Serum measures of mineral bone metabolism (calcium, phosphate, parathyroid hormone, 25-hydroxy vitamin D, FGF23, osteopontin) were measured at enrollment. The primary outcome was markers of sMBD defined as a composite of hypocalcemia, hyperphosphatemia, hyperparathyroidism, or deficiency in 25-OH vitamin D. Secondary outcomes included individual abnormalities in mineral metabolism. The Kidney Disease: Improving Global Outcomes (KDIGO) guidelines were used to define SCA-associated acute kidney injury (AKI). AKI was further assessed using urine NGAL as a marker of tubular injury. Acute kidney disease (AKD) was defined as a composite of AKI, an eGFR < 90 ml/min per 1.73 m2 using the Cystatin C GFR equation, or evidence of structural injury (positive biomarker test or albuminuria). Results The mean age of children was 8.9 years and 41.6% were female. The prevalence of sMBD was 47.6%, with hypocalcemia the most frequent abnormality (29.9%, 55/184) followed by hyperphosphatemia (20.7%, 38/184), hyperparathyroidism (8.7%, 16/185), and vitamin D deficiency (5.4%, 10/185). There was no association between sMBD and sKDIGO-defined AKI using serial changes in creatinine or when incorporating biomarkers to define AKI. However, the presence of AKD was associated with a 2.01-fold increased odds of sMBD (95% CI 1.05 to 3.83) and was driven by a decrease in eGFR (OR, 2.90 95% CI: 1.59 to 5.29). When evaluating individual mineral abnormalities, hypocalcemia was associated with AKD and low eGFR while hyperparathyroidism was associated with low eGFR, AKI and structural injury. Vitamin D deficiency was associated with structural kidney injury. Vitamin D deficiency, hyperparathryoidism, and increases in FGF23 and osteopontin predicted mortality (p < 0.05 for all). Conclusion MBD is common among children with SCA hospitalized with VOC. Biomarkers of kidney injury and bone health may help risk stratify children at risk of sMBD. Routine evaluation of sMBD in children with SCA may improve long-term bone health.

Abstract
Aim: Protein-bound uremic toxins (PBUTs) may displace drugs from the plasma proteins and render them more liable to clearance. This study aims to investigate the possible interplay between PBUTs and directly acting antivirals (DAAs). Methods: PBUT plasma protein binding was compared to those of paritaprevir (PRT), ombitasivir (OMB) and ritonavir (RTV) in silico to assess the possible competitive displacement. The three drugs were LC-MS/MS determined in seven patients across dialysis and non-dialysis days and results were compared. Results & conclusion: Results showed that the PBUT exhibited a lower binding than DAA reducing the liability of their competitive displacement. This was echoed by an unaltered plasma concentration across dialysis days. Results may indicate that PBUT accumulation may have limited effect on disposition of DAA.

Abstract
Background Patients who exceed their expected length of stay in the hospital come at a cost to stakeholders in the healthcare sector as bed spaces are limited for new patients, nosocomial infections increase and the outcome for many patients is hampered due to multimorbidity after hospitalization. Objectives This paper develops a technique for predicting Extended Length of Hospital Stay (ELOHS) at preadmission and their risk factors using hospital data. Methods A total of 91,468 records of patient’s hospital information from a private acute teaching hospital were used for developing a machine learning algorithm relaying on Recursive Feature Elimination with Cross-Validation and Extra Tree Classifier (RFECV-ETC). The study implemented Synthetic Minority Oversampling Technique (SMOTE) and tenfold cross-validation to determine the optimal features for predicting ELOHS while relying on multivariate Logistic Regression (LR) for computing the risk factors and the Relative Risk (RR) of ELOHS at a 95% confidence level. Results An estimated 11.54% of the patients have ELOHS, which increases with patient age as patients < 18 years, 18–40 years, 40–65 years and ≥ 65 years, respectively, have 2.57%, 4.33%, 8.1%, and 15.18% ELOHS rates. The RFECV-ETC algorithm predicted preadmission ELOHS to an accuracy of 89.3%. Age is a predominant risk factors of ELOHS with patients who are > 90 years—PAG (> 90) {RR: 1.85 (1.34–2.56), P: < 0.001} having 6.23% and 23.3%, respectively, higher likelihood of ELOHS than patient 80–90 years old—PAG (80–90) {RR: 1.74 (1.34–2.38), P: < 0.001} and those 70–80 years old—PAG (70–80) {RR: 1.5 (1.1–2.05), P: 0.011}. Those from admission category—ADC (US1) {RR: 3.64 (3.09–4.28, P: < 0.001} are 14.8% and 70.5%, respectively, more prone to ELOHS compared to ADC (UC1) {RR: 3.17 (2.82–3.55), P: < 0.001} and ADC (EMG) {RR: 2.11 (1.93–2.31), P: < 0.001}. Patients from SES (low) {RR: 1.45 (1.24–1.71), P: < 0.001)} are 13.3% and 45% more susceptible to those from SES (middle) and SES (high). Admission type (ADT) such as AS2, M2, NEWS, S2 and others {RR: 1.37–2.77 (1.25–6.19), P: < 0.001} also have a high likelihood of contributing to ELOHS while the distance to hospital (DTH) {RR: 0.64–0.75 (0.56–0.82), P: < 0.001}, Charlson Score (CCI) {RR: 0.31–0.68 (0.22–0.99), P: < 0.001–0.043} and some VMO specialties {RR: 0.08–0.69 (0.03–0.98), P: < 0.001–0.035} have limited influence on ELOHS. Conclusions Relying on the preadmission assessment of ELOHS helps identify those patients who are susceptible to exceeding their expected length of stay on admission, thus, making it possible to improve patients’ management and outcomes.

Abstract
Increased muscle protein catabolism leading to muscle wasting is a prominent feature of the syndrome of protein-energy wasting (PEW) in patients with chronic kidney disease (CKD). PEW and muscle wasting are induced by factors such as inflammation, oxidative stress and metabolic acidosis that activate the ubiquitin-proteasome system, the main regulatory mechanism of skeletal muscle degradation. Whether deficiency of nuclear factor erythroid 2-related factor 2 (NRF2), which regulates expression of antioxidant proteins protecting against oxidative damage triggered by inflammation, may exacerbate PEW has yet to be examined in aging patients with CKD. This review focuses on the hypothesis that NRF2 is involved in the maintenance of muscle mass and explores whether sustained activation of NRF2 by non-pharmacological interventions using nutraceutical activators to improve redox homeostasis could be a plausible strategy to prevent skeletal muscle disorders, including muscle wasting, sarcopenia and frailty associated with PEW in aging CKD patients.

IRANIAN JOURNAL OF BASIC MEDICAL SCIENCES 2022; 25:1317-1325.

Abstract
OBJECTIVES Chronic kidney disease (CKD), accompanied by renal dysfunction, fibrosis, and apoptosis, is highly prevalent in postmenopausal women. We tested the hypothesis that isoflavone daidzein may ameliorate renal dysfunction and fibrosis through angiotensin II type 1 (AT1R) and angiotensin 1-7 (MasR) receptors in association with microRNAs 33a and 27a. MATERIALS AND METHODS Two weeks before the initiation of the experiments, rats (n=84) underwent ovariectomy (OVX). Then, unilateral ureteral obstruction (UUO) was performed in OVX rats, and animals were allocated to the following groups (n=21): sham vehicle (dimethyl sulfoxide; DMSO 1%), UUO vehicle, UUO+17β-estradiol (E2), and UUO+daidzein. Each group encompassed three subgroups (n=7) treated with saline, A779 (MasR antagonist), or losartan (AT1R antagonist) for 15 days. The fractional urine excretion of sodium (FENa+) and potassium (FEK+), renal failure index (RFI), renal interstitial fibrosis (RIF index), glomerulosclerosis, miR-33a, and miR-27a expressions and their target genes were analyzed. Apoptosis was measured via cleaved caspase-3 immunohistochemistry. RESULTS UUO increased kidney weight, FENa+, FEK+, urine calcium, RFI, RIF index, glomerulosclerosis, and cleaved caspase-3. Moreover, expression of renal miR-33a and miR-27a, collagen3A1 mRNA, and protein were up-regulated post-UUO. Daidzein treatment alleviated the harmful effects of UUO especially in co-treatment with losartan. They also masked the anticipated worsening effects of A779 on UUO. CONCLUSION Compared with E2, daidzein efficiently ameliorated renal dysfunction, fibrosis, and apoptosis through modulation of miR-33a and miR-27a expression and their crosstalk with AT1R and MasR. Therefore, daidzein might be a promising candidate for treating CKD in postmenopausal and older women.

[PMID: 36085065 PMCID: PMC9461254 DOI: 10.1186/s12906-022-03717-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2021] [Accepted: 08/31/2022] [Indexed: 11/10/2022] Open
Abstract
Abstract
Background
There is paucity of data regarding effects of guided meditation (Yoganidra) on quality of life among patients of chronic kidney disease on maintenance hemodialysis. Our objective was to study effects of guided meditation on physical, emotional, and cognitive dimensions of well-being and quality of life in patients undergoing maintenance hemodialysis.
Method
We collected baseline and post intervention data in control and intervention groups on hemodialysis and studied the effect of Guided mediation provided for 6 weeks.
Result
Eighty patients (forty in control and intervention group each) were studied. Mean age was 51 years. Hypertension and Diabetes were the most common etiological condition (28.75%) followed by undermined aetiology (25.00%). 8.75% of the patients had dialysis vintage of less than 1 year. There was statistically significant difference in qualities of happiness and all measures of physical general wellbeing. There was statistically significant difference in burden and effect of kidney disease as well as symptoms of kidney disease post intervention in Kidney Disease Quality of Life score. We carried out Qualitative analysis in our study by maintaining a diary of their subjective experiences related to listening music/guided meditation during the study period in which the feeling of peace and feeling inspired to manage the illness/ do regular work were the most common experiences (97.5%) reported by participants.
Conclusion
Guided meditation resulted in statistically significant improvement in happiness, enthusiasm, inspiration, activeness, alertness, awareness, degree of stability, self-confidence, clarity of thoughts, control over anger, self-reflection intervention in the intervention group. It reduced perceived stress. It improved burden and effect of kidney disease, symptoms of kidney disease and total Kidney Disease Quality of Life score. In qualitative dimensions of wellbeing (as emerging from analysis of results of diary), feeling of peace and feeling inspired to manage the illness/ continue regular work, clarity of thoughts, happiness, concentration, reduction of laziness, improved sleep pattern, reduction in anger among other psychological components.
Trial registration
This trial has been registered under clinical trial registry of India. (CTRI number-CTRI/2020/02/023438) (Date: 19/02/2020).

Association of Physical Performance, Muscle Strength and Body Composition with Self-Assessed Quality of Life in Hemodialyzed Patients: A Cross-Sectional Study. J Clin Med 2022; 11:jcm11092283. [PMID: 35566409 PMCID: PMC9103996 DOI: 10.3390/jcm11092283] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2022] [Revised: 03/26/2022] [Accepted: 04/04/2022] [Indexed: 12/03/2022] Open
Abstract
(1) Patients on chronic hemodialysis (HD) experience impaired quality of life (QoL). We analyzed HD’s relationship with physical performance, body composition, and muscle strength; (2) QoL was assessed with the Short Form-36, composed of physical (PCS) and mental (MCS) health dimensions. Physical performance was assessed with the Short Physical Performance Battery (SPPB), body composition (lean tissue mass% (LTM%), fat tissue mass% (FTM%), and skeletal muscle mass% (SMM%)) was assessed with bioelectrical impedance, and lower extremity strength was assessed with a handheld dynamometer; and (3) we enrolled 76 patients (27 F, 49 M), age 62.26 ± 12.81 years, HD vintage 28.45 (8.65−77.49) months. Their QoL score was 53.57 (41.07−70.64); their PCS and MCS scores were 52.14 (38.69−65.95) and 63.39 (44.64−76.79) and strongly correlated (p < 0.0001, R = 0.738). QoL correlated positively with SPPB (R = 0.35, p ≤ 0.001), muscle strength (R from 0.21 to 0.41, p < 0.05), and LTM% (R = 0.38, p < 0.001) and negatively with FTM% (R = −0.32, p = 0.006). PCS correlated positively with SPPB (R = 0.42 p < 0.001), muscle strength (R 0.25−0.44, p < 0.05), and LTM% (R = 0.32, p = 0.006) and negatively with FTM% (R = −0.25, p = 0.031). MCS correlated positively with SPPB (R = 0.23, p = 0.047), SMM% (R = 0.25; p = 0.003), and LTM% (R = 0.39, p < 0.001) and negatively with FTM% (R = −0.34; p = 0.003). QoL was unrelated to sex (p = 0.213), age (p = 0.157), HD vintage (p = 0.156), and BMI (p = 0.202); (4) Better physical performance, leaner body composition, and higher muscle strength are associated with better mental and physical QoL in HD.

Abstract
A microfluidic paper-based thermoplastic electrode (TPE) array has been developed for point-of-care detection of Na+ and K+ ions using a custom-made portable potentiometer. TPEs were fabricated using polystyrene as the binder and two different types of graphite to compare the electrode performance. The newly designed TPE array embedded in a polymethyl methacrylate chip consists of two working electrodes modified with carbon black nanomaterial and an ion-selective membrane, and an all-solid-state reference electrode modified with Ag/AgCl ink and poly(butyl methacrylate-co-methyl methacrylate) membrane via drop-casting. Ion-selective membrane compositions and conditioning steps were optimized. Under optimized conditions, ion-selective TPEs demonstrated fast response time (4 s) and good stability. The TPE array demonstrated a Nernstian behavior for K+ with a sensitivity of 59.2 ± 0.2 mV decade-1 and near-Nernstian response for Na+ with a sensitivity of 54.0 ± 1.1 mV decade-1 in the range 10-1 - 10-4 M and 1 - 10-3 M, respectively. The detection limits were 1 × 10-5 M and 1 × 10-4 M for K+ and Na+, respectively. In addition, a K+ and Na+ selective microfluidic paper-based analytical device (µPAD) was applied to artificial serum analysis and found in good agreement with average recoveries of 101.3% and 99.7%, respectively, suggesting that the developed ISE array is suitable for detection of sodium and potassium in complex matrix.

Abstract
Notwithstanding the groundbreaking achievement of hepatitis C curative treatment with direct-acting antiviral therapies, Canada faces an uphill battle in reaching the 2030 goal of viral elimination set forth by the World Health Organization, a goal made more difficult by the COVID-19 pandemic. There is limited understanding of the diagnostic and treatment barriers, and challenges in linkage to care in Canada, especially as it pertains to primary care providers in a community context. Therefore, in this article, the authors conducted a survey study to evaluate the following factors: primary care providers’ knowledge of specialist treatment options and the importance of screening and treatment; and patient factors, including transportation, linguistic barriers, and other socio-economic status indicators that impact the screening and management of hepatitis C. The results suggest that public health campaigns that protocolize and/or incentivize screening and referrals may provide solutions to addressing such barriers.

Abstract
OBJECTIVE The clinical use of tacrolimus is limited due to its side effects. This research investigated the protective activities of pomegranate seed oil (PSO) against TAC toxicity. MATERIALS AND METHODS The groups are included normal (1 ml of corn oil), TAC (2 mg/kg), and co-treatment of PSO (0.4 and 0.8 ml/kg) and TAC. All administrations were carried out intraperitoneally for 14 days. After the last injection, blood was collected from the heart. RESULTS TAC increased creatinine and urea. Increased malondialdehyde, reduced thiol content and superoxide dismutase. The elevation of lactate dehydrogenase, aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine kinase-MB and creatinine phosphokinase that confirmed cardiac toxicity. PSO reduced TAC toxicity. PSO decreased TAC-induced pathology injury. CONCLUSION PSO reduced TAC toxicity in renal and heart via scavenging free radicals.

Effectiveness of anisodamine for the treatment of critically ill patients with septic shock: a multicentre randomized controlled trial. Crit Care 2021; 25:349. [PMID: 34579741 PMCID: PMC8474812 DOI: 10.1186/s13054-021-03774-4] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2021] [Accepted: 09/16/2021] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Septic shock is characterized by an uncontrolled inflammatory response and microcirculatory dysfunction. There is currently no specific agent for treating septic shock. Anisodamine is an agent extracted from traditional Chinese medicine with potent anti-inflammatory effects. However, its clinical effectiveness remains largely unknown. METHODS In a multicentre, open-label trial, we randomly assigned adults with septic shock to receive either usual care or anisodamine (0.1-0.5 mg per kilogram of body weight per hour), with the anisodamine doses adjusted by clinicians in accordance with the patients' shock status. The primary end point was death on hospital discharge. The secondary end points were ventilator-free days at 28 days, vasopressor-free days at 28 days, serum lactate and sequential organ failure assessment (SOFA) score from days 0 to 6. The differences in the primary and secondary outcomes were compared between the treatment and usual care groups with the χ2 test, Student's t test or rank-sum test, as appropriate. The false discovery rate was controlled for multiple testing. RESULTS Of the 469 patients screened, 355 were assigned to receive the trial drug and were included in the analyses-181 patients received anisodamine, and 174 were in the usual care group. We found no difference between the usual care and anisodamine groups in hospital mortality (36% vs. 30%; p = 0.348), or ventilator-free days (median [Q1, Q3], 24.4 [5.9, 28] vs. 26.0 [8.5, 28]; p = 0.411). The serum lactate levels were significantly lower in the treated group than in the usual care group after day 3. Patients in the treated group were less likely to receive vasopressors than those in the usual care group (OR [95% CI] 0.84 [0.50, 0.93] for day 5 and 0.66 [0.37, 0.95] for day 6). CONCLUSIONS There is no evidence that anisodamine can reduce hospital mortality among critically ill adults with septic shock treated in the intensive care unit.

Abstract
Background Lung protective ventilation with low tidal volume (TV) and increased positive end-expiratory pressure (PEEP) can have unfavorable effects on the cardiovascular system. We aimed to investigate whether lung protective ventilation has adverse impact on hemodynamic, renal and hormonal variables. Methods In this randomized, single-blinded, placebo-controlled study, 24 patients scheduled for robot-assisted radical prostatectomy were included. Patients were equally randomized to receive either ventilation with a TV of 6 ml/IBW and PEEP of 10 cm H2O (LTV-h.PEEP) or ventilation with a TV of 10 ml/IBW and PEEP of 4 cm H2O (HTV-l.PEEP). Before, during and after surgery, hemodynamic variables were measured, and blood and urine samples were collected. Blood samples were analyzed for plasma concentrations of electrolytes and vasoactive hormones. Urine samples were analyzed for excretions of electrolytes and markers of nephrotoxicity. Results Comparable variables were found among the two groups, except for significantly higher postoperative levels of plasma brain natriuretic peptide (p = 0.033), albumin excretion (p = 0.012) and excretion of epithelial sodium channel (p = 0.045) in the LTV-h.PEEP ventilation group compared to the HTV-l.PEEP ventilation group. In the combined cohort, we found a significant decrease in creatinine clearance (112.0 [83.4;126.7] ml/min at baseline vs. 45.1 [25.4;84.3] ml/min during surgery) and a significant increase in plasma concentrations of renin, angiotensin II, and aldosterone. Conclusion Lung protective ventilation was associated with minor adverse hemodynamic and renal effects postoperatively. All patients showed a substantial but transient reduction in renal function accompanied by activation of the renin-angiotensin-aldosterone system. Trial registration ClinicalTrials, NCT02551341.

Abstract
OBJECTIVE To explore the mechanism of Simiao pills for treatment of hyperuricemia based on network pharmacology and molecular docking. OBJECTIVE The active ingredients of Simiao pills and their targets of action were predicted using TCMSP, SEA, Swiss and PharmMapper databases. GeneCards and TCD databases were searched for the disease targets related to hyperuricemia. Cytoscape 3.6.1 was used to construct a protein-protein interaction network. GO enrichment analysis and KEGG pathway analysis were carried out on the STRING platform. The binding between the main compounds and the key targets were predicted using the SwissDock platform for molecular docking. OBJECTIVE We identified 28 active ingredients and 429 potential targets in Simiao pills, 494 disease targets related to hyperuricemia, and 118 common targets between Simiao pills and hyperuricemia. Several key targets including AKT1, IL- 6, JUN, TNF and CASP3 were screened for molecular docking, which had good binding activities with berberrubine, epiberberine, stigmasterol and sitosterol. AKT1, IL-6, JUN, TNF and CASP3 were predicted to be the key targets for Simiao pills for treating hyperuricemia. KEGG pathway enrichment analysis showed that Simiao pills produced therapeutic effects on hyperuricemia through multiple signaling pathways including the TNF signaling pathway, apoptosis signaling pathway and IL-17 signaling pathway. OBJECTIVE Simiao pills produces therapeutic effects on hyperuricemia through multiple components and targets and the synergy of several pathways. Our finding provides a theoretical basis for further study of the active ingredients and therapeutic mechanism of Simiao pills for treating hyperuricemia.

Abstract
The response to pazopanib in patients with metastatic renal cell carcinoma (mRCC) has been found to differ in Western and Eastern populations. Here, we analyzed the efficacy and side effects of pazopanib as first-line therapy in 31 consecutive patients with mRCC who were treated at a single Chinese center. Thirty-one consecutive patients with mRCC (20 males and 11 females, median age 59 years) were treated with pazopanib between October 2017 and July 2019. All patients had received a pathological diagnosis of RCC by prior radical nephrectomy or biopsy. All cases were treated with pazopanib (800 mg/day orally) as first-line therapy. Administration was continued until disease progression or unacceptable toxicities occurred. Objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety were evaluated. Twenty-nine patients were eligible for final analysis. At the median follow-up of 12.7 months, 34.5% (10/29) patients achieved a partial response (PR), 41.4% (12/29) patients had stable disease (SD), seven (24.1%) patients had disease progression (PD), and one patient had died. The ORR and DCR were 34.5% and 75.9%, respectively, and the median PFS was 10.1 months (95% confidence interval, 4.1–17.7 months). OS could not be determined. The most common side effects were fatigue (11 cases, 37.9%), hand-foot syndrome (10 cases, 34.5%), change of hair color (10 cases, 34.5%), elevated alanine transaminase (ALT)/aspartate transaminase (AST) (10 cases, 34.5%), hypertension (seven cases, 24.1%), neutropenia (three cases, 10.3%), anemia (three cases, 10.3%), thrombocytopenia (two cases, 6.9%), and diarrhea (one cases, 3.4%). Major (grade 3 or higher) adverse events included hand-foot syndrome (two cases, 6.9%) and thrombocytopenia (one case, 3.4%). Most adverse events were ameliorated by dose reduction or treatment interruption. Remissions occurred in almost all patients with local recurrence or pulmonary metastases, whereas PD occurred in patients with bone, liver or brain metastases. Our real-world data suggest that pazopanib is definitely efficacious as first-line therapy for mRCC, with well-tolerated side effects. Different metastatic lesions may have different sensitivity to pazopanib. An additional, large sample, multicenter, prospective study is needed to confirm our results.

[PMID: 31992241 PMCID: PMC6986027 DOI: 10.1186/s12887-020-1939-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2019] [Accepted: 01/22/2020] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND The relationship between constipation and childhood nocturnal enuresis (NE) has been previously reported; however, this relationship remains controversial. The present study aimed to evaluate the association between constipation and childhood NE. METHODS Data from the Longitudinal Health Insurance Database 2000 (LHID 2000) of Taiwan National Health Insurance Research Database from 2000 to 2013 were collected. A total of 2286 children were enrolled in this study: a case group of 1143 children aged 5-18 years who were diagnosed with NE (NE group) and an age- and sex-matched control group of 1143 children without NE. Conditional logistic regression and odds ratio (OR) for NE were used to examine the association between constipation and childhood NE. RESULTS The prevalence of NE in the case group (NE group, aged 5-18 years) was 1.03% from 2000 to 2013. The NE group had a higher percentage of constipation in 1 year before the diagnosis of NE. After stratification for sex, both boys and girls with constipation had higher OR for NE. With stratification for age, children aged 5-12 and 7-12 years had a higher OR for NE. CONCLUSIONS Constipation is associated with childhood NE in Taiwan, particularly in children aged 5-7 and 7-12 years.
