Introduction: Determination of dry weight is one of the daily goals to achieve in hemodialysis. The aim of this study was to validate the use of bioelectrical impedance analysis (BIA) in estimation of dry weight in a population of Senegalese chronic hemodialysis patients. Patients and methods: A 9-week cross-sectional study was carried out at the hemodialysis unit of Aristide Le Dantec University Hospital. Adult patients with no previous hospital history were included. The total body water (TBW) was measured with a single frequency bioelectric impedance foot-to-foot analyzer, before and after six successive hemodialysis sessions. These results were compared with those from clinical measurements with the Watson equation using a Student’s t-test and Bland-Altman analysis. Results: 264 measurements were made in 22 patients (46.6 years, 54.5% men, 92.3 months on dialysis, 62.7 kg mean dry weight). A significant reduction in weight (ΔWeight = 2.0 ± 1.1 kg; p < 0.0001) and in TBW measured by the BIA (ΔTBWBIA = 3.3 ± 1.0 liters; p < 0.0001)) or calculated by Watson’s equation (ΔTBWWatson = 0.5 ± 0.2 liter; p = 0.0001) was observed. There was a strong linear correlation and agreement between the 2 TBW measurements in pre-dialysis. In post-dialysis the concordance diagram indicated a bias = –2.2 and wide agreement limits. Conclusion: The BIA allows reproducible and reliable measurements and a fair estimate of the TBW in pre-dialysis.

Abstract Background and Aims The Chronic kidney disease (CKD), like many chronic illnesses, is invariably associated with various psychiatric conditions and poorer quality of life. This study aims to assess the prevalence of depression and anxiety among CKD patient and their determinant factors. Method this is a cross sectional single center study in a Moroccan university hospital. Patients aged ≥ 18 years old and followed for more than one year were included. The data was collected using a questionnaire for sociodemographic and clinical information and the Hospital anxiety and depression scale (HADS) to assess depression and anxiety prevalence. After the description of the population’s characteristics, the statistical analysis aimed to assess the association between depression and anxiety disorders and the estimated glomerular filtration rate before and after adjustment on several confounding factors. Results 88 patients were included (63.6% of them were women, the mean age was 61.8±14.0 years), 21 were on stage 3, 46 were on stage 4, and 21 were on stage 5 of the CKD. The median of depression sub-score was 5.00[2.00; 10.0], the median of anxiety sub-score was 6.00[4.00; 9.00], and the median of the global score was 11.0[7.00; 20.0], 22.0% of included patients had depression and 22.0% had anxiety. Both depression and anxiety scores were associated to eGFR before and after adjustment (p= 0.001, p&lt;0.001and p=0.04, p=0.03 respectively). Conclusion This study showed that depression and anxiety are strongly related to the CKD progression, which should motivate both doctors and nurses to improve their psychological care toward CKD patients.

Abstract Background and Aims Despite progress these recent years in support the hemodialysis, chronic pain remains a problem concern that ultimately affect the quality of life and psycho-emotional state, even among dialysis patients already psychologically fragile. However, it is often overlooked and its characteristics in chronic hemodialysis (HDC) are poorly understood. The purpose of this study was to evaluate the prevalence, features, impact and treatment of pain in our population of chronic hemodialysis patients and to determine the factors associated with it. Method cross-sectional study conducted in January 2020 including 71 chronic hemodialysis patients from the nephrology department of the CHU ibn rochd CASABLANCA. They were subjected to a questionnaire on socio-demographic characteristics, the characteristics of the pain, its impact on daily life, the various treatments performed. The pain is chronic if it persists for more than 3 months. The intensity was assessed using a visual analog scale. Results Of the 71 patients, 64.4% report chronic pain, the average age of our patients was 46.5 years, ranging from 16 to 93 years, with a sex ratio M/F 1.1, seniority hemodialysis was 17.3 years. The pain is continuous, frequent, intermittent and rare in respectively 55.5%, 27.5%, 13.7%, 3.44% of cases, it is a weak, moderate, severe, very severe in respectively: 13.7%, 58.6%, 17.24%, 10.3%, causing musculoskeletal was predominant in 75.8% of cases, the most common sites are: shoulders (47,23%), knees (34.5%), the head (41.2%) and the back (19.65%). It resounded on the patient's daily activity in 55.17%, and sleep in 41.3%, the treatment was essentially based analgesics in 58.6% of cases, these analgesics were level 1 in 47.1% cases and level 2 in 52.9% of cases. This is taken daily in 28.5% of patients, common in 42.8% and 28.5% rare among of them, the disappearance of pain was achieved in 65.51% of cases. In perdialyse, the intensity of the pain does not change in 79.4% of patients. Pain was favored by advanced age and age dialysis (advanced age (p = 0.043) and age dialysis (p = 0.01).) Conclusion Chronic pain is a major problem in hemodialysis by its high prevalence, its significant intensity and its impact on life daily patient. However its management remains inadequate. Regular assessment of pain using a well-codified questionnaire is necessary to improve the care of dialysis patients.

Objectives: To investigate practicality and repeatability of a handheld compared to a state-of-the-art multisegmental bioelectrical impedance analysis (BIA) device to facilitate screening of sarcopenia in older inpatients. Design and setting: Cross-sectional study in a geriatric rehabilitation hospital. Participants: 207 inpatients aged 70+. Measurements: In a first phase, appendicular skeletal muscle mass index (ASMI) was measured using the handheld Biody xpertZm II BIA device (n=100). In a second phase, ASMI was obtained using the multisegmental Biacorpus RX 4004M device (n=107). Repeatability of BIA devices was compared in subgroups of patients (handheld BIA device: n=36, multisegmental BIA device: n=46) by intra-class correlation (ICC) and Bland-Altman plots. Results: Overall, measurement failure was seen in 31 patients (31%) tested with the handheld BIA device compared to one patient (0.9%) using the multisegmental BIA device (p<0.001). Main reasons for measurement failure were inability of patients to adopt the position necessary to use the handheld BIA device and device failure. The mean difference of two ASMI measurements in the same patient was 0.32 (sd 0.85) using the handheld BIA device compared to 0.02 kg/m2 (sd 0.07) using the multisegmental device (adjusted mean difference between both groups -0.35, 95% confidence interval (CI) -0.61 to -0.09 kg/m2). Congruently, Bland-Altman plots showed poor agreement with the handheld compared to the multisegmental BIA device. Conclusion: The handheld BIA device is neither a practical nor reliable device for assessing muscle mass in older rehabilitation inpatients.

Arteriosclerosis is a constant problem in long-term hemodialysis patients. Computer tomography of the abdominal aorta allows a well-defined and reproducible evaluation of aortosclerosis. In the cross-sectional study, aortosclerosis was significantly accelerated in 84 chronic hemodialysis patients and was comparable to the results found in 20-year older control patients without renal disease. The increase of aortosclerosis correlated significantly with age of the patient, smoking, and duration of dialysis therapy. Furthermore, increased VLDL cholesterol and decreased HDL cholesterol seem to enhance aortosclerosis in our dialysis patients. In the longitudinal study (two CT scans with a time interval of 87 ± 62.7 months) in 36 dialysis patients, progressed aortosclerosis correlated significantly with the long duration of hypertriglyceridemia, VLDL cholesterol, uric acid, and calcium phosphate products. Progression of aortosclerosis was reduced in parathyroidectomized patients. The study suggests that premature aortosclerosis is found in dialysis patients. In addition to the common risk factor of aortosclerosis, disturbed calcium phosphate and parathyroid hormone metabolism seem to enhance aortosclerosis in patients under maintenance hemodialysis.

ObjectivesBioelectrical impedance analysis (BIA) is a simple and inexpensive method to estimate body composition. However, the accuracy of BIA is unknown. We aimed to assess the accuracy of BIA in estimating visceral fat area (VFA) in patients with gastric cancer.Study designThis was a cross-sectional study comparing the accuracy of BIA in estimating VFA with the gold standard method measured by CT. VFA was measured in enrolled patients both by CT and BIA. VFA by CT at umbilical level ≥100 cm2 was considered as visceral obesity. Reliability between the two methods was assessed by intraclass correlation coefficient (ICC) and consistency was assessed by Bland-Altman method (95% limits of agreement). The area under the receiver operating characteristic curve (AUROC) was used to assess the performance of BIA in diagnosing visceral obesity.SettingThe study was conducted in China.ParticipantsFrom 1 January 2017 to 1 December 2018, a total of 157 patients diagnosed with gastric cancer were enrolled.ResultsOverall, VFA by CT and BIA in patients was 84.39±46.43 cm2 and 71.94±22.44 cm2, respectively. VFA estimated by BIA was positively correlated with VFA measured by CT using Pearson’s test (r=0.650, p<0.001). Overall, ICC for the two methods was 0.675. The mean bias between the two measurements was 12.45±36.13 cm2. The 95% limits of agreement ranged from −58.36 cm2 to 83.26 cm2. The cut-off value for diagnosing visceral obesity by BIA was 81 cm2 (AUROC: 0.822, p<0.001, 95% CI 0.758 to 0.887).ConclusionsVFA measured by BIA showed satisfactory reliability with that measured by CT. However, the absolute values of the two methods were not interchangeable. The cut-off value for VFA by BIA in diagnosing visceral obesity was 81 cm2 for patients with gastric cancer in the Chinese population.

Background. Body composition measurement is very important for early nutritional care in hemodialysis patients. Dual-energy X-ray absorptiometry (DXA) is a gold standard test, but clinically limited. Bioelectrical impedance analysis (BIA) with multifrequency technique is a practical and reliable tool. Objective. This cross-sectional study was aimed to compare the agreement of BIA with DXA in measurement of body composition in hemodialysis patients and to evaluate their associated factors. Methods. Body composition was measured by 2 BIA methods (InBody S10 and InBody 720) and DXA after a hemodialysis session. A total of 69 measurements were included. Pearson’s correlation and Bland and Altman analysis were used to determine the correlation of body composition between methods and to compare the methods agreement, respectively. Results. The correlation coefficients of body compositions were strong between DXA and InBody S10 (fat mass index (FMI): r=0.95, fat-free mass index (FFMI): r=0.78) and also between DXA and InBody 720 (FMI: r=0.96, FFMI: r=0.81). Comparing to DXA, the means of each body composition measured by InBody S10 method were not significantly different in each gender, but differences were found in FM, %FM, and FMI measured by InBody 720. Conclusions. In maintenance hemodialysis patients, the measurement of body composition with DXA and both BIA methods had highly significant correlations; practically, BIA method could be used as an instrument to follow FM and FFM and to measure the edematous stage. Further studies with large populations are warranted.
