BACKGROUND: Haemodialysis (HD) patients usually engage in a low level of physical activities, which could impact the prognosis and mortality of this group. Fitness Qigong Baduanjin, a physical exercise from traditional Chinese Medicine, is known to have benefit in chronic heart failure patients and peritoneal dialysis patients. However, researches about Baduanjin in HD patients are currently limited. So, the aim of the study is to investigate the current exercise intensity of HD patients and its influencing factors, and to explore the effects of Baduanjin on HD patients.
METHODS: This prospective, non-blinded, randomised controlled trial will enrol patients with end-stage kidney disease who were stable on HD for more than 3 months. All eligible participants will be randomly divided into the intervention group undergoing Baduanjin and the control group without Baduanjin in a 1:1 ratio. The intervention group is required to perform Baduanjin two times per day, starting 30 min after breakfast and dinner, 45 min per session for a total of a 6 month, starting from 10 June 2024. Information such as laboratory biochemical examination indicators, radiological examination results and related scales and questionnaires will be collected at baseline, 1 month follow-up, 3 month follow-up and 6 month follow-up. All statistical tests are conducted through the two-tailed test, and a p-value≤0.05 will be considered statistically significant for the difference being tested. The description of quantitative indicators will be used in calculating the number of cases, mean, SD, median and IQR method. The classification indicators will be used to describe the number of cases and percentages (frequency and frequency rate).
BACKGROUND: The study protocol was approved by the Ethics Committee of the First Affiliated Hospital of Zhejiang Chinese Medical University (V20230521). The results will be reported in a peer-reviewed journal and a relevant academic conference.

Dental caries and periodontal disease are typical oral diseases frequently observed in patients with renal diseases. Tooth loss is an outcome of dental caries and periodontal disease, and the number of existing teeth is an indicator of oral health status. However, the association between the number of existing teeth and end-stage kidney disease (ESKD) has not been investigated in detail. This study aimed to investigate the association between oral health status, expressed by the number of existing teeth, and ESKD. We analyzed data from the second survey of the Longitudinal Evaluation of Multi-phasic, Odontological, and Nutritional Associations in Dentists, a cohort study conducted among members of the Japan Dental Association. From August 2016 to July 2017, self-administered questionnaires were mailed to 16,128 male dentists and 8,722 responded. Among them, 7,479 men with complete data on age, number of existing teeth, and ESKD were included in the analysis. Multivariate logistic regression analysis was conducted, with ESKD as the dependent variable and the number of existing teeth (≥23 teeth and <23 teeth) as the independent variable. Subgroup analysis by age (<65 years and ≥65 years) was also conducted. The <23 teeth group had a significantly higher rate of ESKD than did the ≥23 teeth group. After adjusting for age, body mass index, smoking habits, hypertension, and diabetes mellitus, there was no significant association between having <23 teeth and ESKD in all participants. However, the subgroup analysis revealed a significant association after adjustment for covariates in participants aged <65 years but not in those aged ≥65 years. In conclusion, having <23 teeth was associated with the risk of requiring maintenance dialysis therapy among Japanese men aged <65 years. Therefore, tooth loss may be associated with renal function decline.

BACKGROUND: Adherence to diet is effective for metabolic control in patients on hemodialysis. There are educational pamphlets or booklets to improve patients\' knowledge about healthy diets. As video presentation is more desirable than the presentation of readable materials, we designed an educational video on healthy diets in renal failure patients who was played during several sessions of hemodialysis. We compared the effect of this modality on the knowledge, attitudes and metabolic control of the patients before and after the intervention.
METHODS: In this interventional study, all the patients who were referred to the hemodialysis ward at Ashrafi-Esfahani Medical Center (Tehran, Iran) between May 2018 and March 2019 were enrolled (N = 190). Totally, 130 patients had inclusion criteria. An educational video about a healthy diet was shown seven times (once a week in the first month, once every two weeks in the second month, and once in the third month) during hemodialysis for the patients. The nephrologist prepared a video in the form of a lecture with graphic images for 20 min based on the healthy nutrition of the Kidney Federation of Iran\'s Guide for hemodialysis patients. The questionnaire was completed in terms of awareness and attitudes, and blood and urine tests were performed at the 1st, 3rd, and 12th months. Serum parameters, including electrolytes, lipid profile, CBC-diff, dialysis efficacy (Kt/V), and the URR (urine filtration rate) were examined. Pre and post intervention values were compared via the statistical analysis performed using IBM SPSS. P-Value < 0.05 was significant.
RESULTS: The data of 128 people were analyzed at the end of the study. 55% of patients were 10-40 years old and 60% were male. 56% of patients were illiterate or had an elementary school education. The most common underlying diseases were hypertension and diabetes mellitus. Ten to 19% of participants had enough knowledge about the various components of a healthy diet for patients on hemodialysis. Approximately 25%, 14%, and 45% of the participants consumed a healthy diet for breakfast, lunch and dinner, respectively. A comparison of the mean values of the serum parameters before and after the intervention revealed significant changes in phosphorus, blood urea nitrogen, and hemoglobin with mean differences of -118.41 ± 22.84, 21.51 ± 10.38 (both P < 0.001), and 0.29 ± 1.18 (P = 0.044), respectively. The mean Kt/V was similar at all phases.
CONCLUSIONS: The use of an educational video was effective for normalizing the metabolic parameters in patients under hemodialysis and can be an appropriate option, especially for illiterate patients.

UNASSIGNED: Little is known about the effect of combined exposure to different air pollutants on mortality in dialysis patients. This study aimed to investigate the association of multiple exposures to air pollutants with all-cause and cause-specific death in dialysis patients.
UNASSIGNED: This registry-based nationwide cohort study included 90,373 adult kidney failure patients initiating maintenance dialysis between 2012 and 2020 identified from the French REIN registry. Estimated mean annual municipality levels of PM2.5, PM10, and NO2 between 2009 and 2020 were combined in different composite air pollution scores to estimate each participant\'s exposure at the residential place one to 3 years before dialysis initiation. Adjusted cause-specific Cox proportional hazard models were used to estimate hazard ratios (HRs) per interquartile range (IQR) greater air pollution score. Effect measure modification was assessed for age, sex, dialysis care model, and baseline comorbidities.
UNASSIGNED: Higher levels of the main air pollution score were associated with a greater rate of all-cause deaths (HR, 1.082 [95% confidence interval (CI), 1.057-1.104] per IQR increase), regardless of the exposure lag. This association was also confirmed in cause-specific analyses, most markedly for infectious mortality (HR, 1.686 [95% CI, 1.470-1.933]). Sensitivity analyses with alternative composite air pollution scores showed consistent findings. Subgroup analyses revealed a significantly stronger association among women and fewer comorbid patients.
UNASSIGNED: Long-term multiple air pollutant exposure is associated with all-cause and cause-specific mortality among patients receiving maintenance dialysis, suggesting that air pollution may be a significant contributor to the increasing trend of CKD-attributable mortality worldwide.

BACKGROUND Crush injury can result in crush syndrome (CS) when the pressure is released from the limb, resulting in ischemia-reperfusion injury and rhabdomyolysis. This retrospective study aimed to evaluate the demographics, clinical findings, management, and outcomes of 377 patients admitted as an emergency with a diagnosis of crush syndrome between February 6 and 16, 2023, following the Türkiye-Syria earthquakes. MATERIAL AND METHODS This observational study retrospectively analyzed CS patients admitted to the emergency service from February 6 to 16, 2023. We collected data on demographics, vital signs, time under debris, blood parameters, hemodialysis needs, outcomes, hospital stay duration, 7-day mortality, diagnoses, and treatments. RESULTS During the study period, 1682 earthquake victims were admitted, with 377 diagnosed with CS included in the study. The mean age was 33.51±0.89 years, with 51.7% male. The mean time under debris was 24.92±1.62 h, and the mean hospital stay was 34.39±1.20 days. Hemodialysis was required for 91 patients (24.1%), and 20 patients (5.3%) died. AKI developed in 23.1% (n=87) of the patients, with 30.5% (n=115) under debris for more than 24 h. Mortality, hospital stay, and AKI rates were higher in those requiring hemodialysis (P<0.001, P=0.003, and P<0.001, respectively). CONCLUSIONS The study highlights a high incidence of AKI, increased hemodialysis needs, and higher mortality in earthquake-related crush syndrome cases. Longer debris entrapment (over 24 h) was common. Early and aggressive fluid resuscitation, beginning in the field and continuing through hospital care, is crucial. Prioritizing this in disaster planning for field personnel is recommended.

Chronic kidney disease (CKD) is linked to an elevated risk of malnutrition and sarcopenia, contributing to the intricate network of CKD-related metabolic disorders. Adipokines and myokines are markers and effectors of sarcopenia and nutritional status. The aim of this study was to assess whether the adipokine-myokine signature in patients on kidney replacement therapy could help identify malnutrition and sarcopenia. The study involved three groups: 84 hemodialysis (HD) patients, 44 peritoneal dialysis (PD) patients, and 52 kidney transplant recipients (KTR). Mean age was 56.1 ± 16.3 years. Malnutrition was defined using the 7-Point Subjective Global Assessment (SGA) and the Malnutrition-Inflammation Score (MIS). Sarcopenia was diagnosed based on reduced handgrip strength (HGS) and diminished muscle mass. Concentrations of adipokines and myokines were determined using the enzyme-linked immunosorbent assay (ELISA). 32.8% of all study participants were identified as malnourished and 20.6% had sarcopenia. For malnutrition, assessed using the 7-Point SGA, in ROC analysis albumin (area under the curve (AUC) 0.67 was the best single biomarker identified. In dialysis patients, myostatin (AUC 0.79) and IL-6 (AUC 0.67) had a high discrimination value for sarcopenia, and we were able to develop a prediction model for sarcopenia, including age, albumin, adiponectin, and myostatin levels, with an AUC of 0.806 (95% CI: 0.721-0.891). Adipokines and myokines appear to be useful laboratory markers for assessing malnutrition and sarcopenia. The formula we propose could contribute to a better understanding of sarcopenia and potentially lead to more effective interventions and management strategies for dialysis patients.

UNASSIGNED: To compare the impact of tunneled cuffed catheters (TCCs) and arteriovenous fistulas (AVFs) on outcomes in elderly hemodialysis (HD) patients.
UNASSIGNED: A retrospective matched cohort study was performed. Propensity score matching (PSM) was applied to balance the baseline conditions, and we compared all-cause mortality, major adverse cardiovascular and cerebrovascular events (MACCEs), hospitalization, and infection rates between AVF and TCC patients ≥70 years old. Cox survival analysis was used to analyze the risk factors for death.
UNASSIGNED: There were 2119 patients from our center in the Chinese National Renal Data System (CNRDS) between 1 January 2010 and 10 October 2023. Among these patients, 77 TCC patients were matched with 77 AVF patients. There was no significant difference in all-cause mortality between the TCC and AVF groups (30.1/100 vs. 33.3/100 patient-years, p = 0.124). Among the propensity score-matched cohorts, no significant differences in Kaplan-Meier curves were observed between the two groups (log-rank p = 0.242). The TCC group had higher rates of MACCEs, hospitalization, and infection than the AVF group (33.7/100 vs. 29.5/100 patient-years, 101.2/100 vs. 79.5/100 patient-years, and 30.1/100 vs. 14.1/100 patient-years, respectively). Multivariate analysis showed that high Charlson comorbidity index (CCI) score was a risk factor for death.
UNASSIGNED: There was no significant difference in all-cause mortality between elderly HD patients receiving TCCs and AVFs. Compared with those with a TCC, elderly HD patients with an AVF have a lower risk of MACCEs, hospitalization, and infection.

BACKGROUND: Erectile dysfunction (ED) is a common sexual problem among men with chronic kidney disease (CKD). The severity of sexual dysfunction tends to worsen with kidney damage. This study aims to evaluate the erectile function and sexual quality of life of adult male CKD patients undergoing hemodialysis (HD) in a hospital located in the Brazilian Amazon.
METHODS: A cross-sectional quantitative study was performed within the HD Sector of the Nephrology Unit including men with CKD aged ≥ 18 years, undergoing ≥ 3 weekly HD sessions for ≥ 3 months who had been sexually active for ≥ 6 months. We used the Male Sexual Quotient (MSQ) to measure sexual satisfaction and the International Index of Erectile Function (IIEF5) to establish erectile function. Statistical analysis was performed with SPSS 21.0 using appropriate tests, such as Mann-Whitney and Kruskal-Wallis (P < 0.05).
RESULTS: Ninety-eight patients (51.68 ± 15.28 years) were evaluated. They were primarily married/or living with a partner (60.20%), with HD time between 1 to 5 years (55.10%), and an average KTV of 1.17. ED prevalence was 66.30%, and it was associated with a higher age group (p = 0.01), lower family income (p = 0.02), diabetes (p = 0.01), lower mean corpuscular hemoglobin (p = 0.04), higher total calcium (p = 0.04), and lower albumin (p = 0.03). Around 75% classified their sex life as regular to excellent.
CONCLUSIONS: Despite the high ED prevalence, most men with CKD in HD reported experiencing regular to excellent sex life. The study underscores the importance of establishing effective screening and conducting routine evaluations regarding sexual issues in these men.

Background: Roxadustat is commonly used to treat renal anemia. However, the potential effects of roxadustat on metabolism and organs other than the kidneys have recently attracted increased attention. Objective: This study aimed to examine the regulatory effects of roxadustat on thyroid hormones and blood lipid metabolism in patients with end-stage kidney disease (ESKD) undergoing hemodialysis. Methods: Eighty ESKD patients on hemodialysis and taking roxadustat were enrolled. Hemoglobin, thyroid hormones (TSH, FT3, FT4), and blood lipid profiles (TC, LDL-C, TG, HDL-C) were assessed before and after treatment. Changes in these parameters were compared, and relevant causative factors were analyzed. Results: Roxadustat significantly increased Hb, lowered TSH, FT4, TC, and LDL-C levels (all P<0.001). Patients were categorized into three groups based on post-treatment TSH inhibition percentage: Q1(≥70%), Q2(30%-70%), Q3(≤30%). Pre-treatment TSH decreased with reduced TSH inhibition (P<0.05). Post-treatment, TC, LDL-C, TSH, FT3, and FT4 increased with reduced TSH inhibition (all P<0.05).TC and LDL-C significantly decreased post-treatment in Q1 and Q2 (P<0.05). Correlation analysis showed a positive correlation between ΔTSH and pre-treatment TSH levels (r=0.732, P<0.001). The proportion of patients with ≥70% TSH inhibition increased with higher pre-treatment TSH levels (P for trend <0.05). ΔLDL-C and ΔTSH were positively correlated (r=0.278, P<0.05), with ΔTSH identified as an influencing factor in multiple linear regression (β=0.133, 95% CI [0.042, 0.223], P<0.05). Conclusion: Roxadustat effectively improves anemia in ESKD patients while inhibiting TSH and FT4 secretion and reducing TC and LDL-C levels. Decreases in TSH levels correlate with baseline TSH levels, and lowered blood lipid levels are associated with decreased TSH levels.

With the increasing number of maintenance hemodialysis (MHD) patients, growing attention has been paid to the quality of care. Strengthening care preparedness of family caregivers is essential to improving the nursing quality. The purpose of this study is to explore the care preparedness level of family caregivers of MHD patients and its influencing factors, so as to provide guidance for the development of targeted care interventions. A total of 237 family caregivers of MHD patients were recruited from the hemodialysis room of two tertiary hospitals in Wuhan using the Convenience sampling method. They were surveyed by the general data questionnaire, Care Preparedness Scale and Positive Aspects of Caregiving. Statistical analysis was conducted using IBM SPSS software, version 21.0. The statistical tests conducted in this study were two-tailed, and a significance level of P < 0.05 was deemed as statistically significant. The care preparedness and positive aspects of caregiving scores of family caregivers of MHD patients were 19.05 ± 5.64 and 31.28 ± 7.28 points, respectively. The care preparedness level of family caregivers was significantly positively correlated with positive aspects of caregiving (P < 0.01). The results of multiple linear regression analysis showed that the total nursing time and whether family caregivers had chronic diseases and positive aspects of caregiving were the main factors influencing their care preparedness (all P < 0.05). These three factors accounted for 49.6% of the variance. The care preparedness of family caregivers of MHD patients remains to be continuously improved. Medical staff should emphasize the important role of total nursing time, whether the caregiver has a chronic disease, and positive aspects of caregiving in improving care preparedness in this population. To achieve this end, medical staff can provide targeted support and guidance for caregivers according to the influencing factors, such as implementing group psychological education, strengthening the training, offering social support, remote intervention (including family caregivers\' education through the media), and so on. Meanwhile, caregivers should be evaluated dynamically, and information and emotional support should be provided for them.
