Based on these methods, the criteria of hydration were established.Results: Of the total sample, 81% met the hydration criteria(urine color = well hydrated, water balance ≥0 ml, and total water intake/weight ≥35 ml/kg), and 19% did not meet the hydration criteria(urine color = not sufficiently hydrated or dehydrated, water balance <0 ml, and total water intake/weight <35 ml/kg). Subjects not meeting the hydration criteria had lower urine pH, negative water balance, and lower water intake. The latter also had higher anxiety status(score=4 vs. 3, P=0.026), weight [(84.7±10.5) kg vs.(80.5±10.2) kg], body mass index [(26.3±3.1) kg/m;vs.(25.2±2.8) kg/m;], body fat [(22.3±5.6)% vs.(18.3±6.5)%], urine specific gravity, and urine color. Using a logistic binary regression model, hydration status was related significantly with the percentage of body fat(P=0.004), but no relation was found with age, comorbidities, or medications. Furthermore, total water intake/weight was positively correlated with percentage of body water(r=0.357, P=0.000) and negatively with body fat(kg)(r=–0.427, P=0.000), percentage of body fat(r=–0.405, P=0.000), and waist/hip ratio(r=–0.223, P=0.002). Based on a linear regression model, total water intake/weight was related significantly with percentage of body fat(P=0.001) and percentage of body water content(P=0.035). No relation was found, however, with waist/hip ratio, age, comorbidities, or medications.Conclusions: These findings all suggest a relationship between hydration status and body composition but also set the bases for future studies that relate hydration status and anxiety status. These results can be used to improve the hydration status and body composition of military personnel.展开更多

The main challenge with chronic haemodialysis patients is indeed the maintenance of a normal extracellular volume through dry weight determination. Our study aimed at assessing the role of lung ultrasound in the detection of B-lines for the determination of hydration status in chronic HD patients. Methods: We conducted a cross-sectional study including 31 patients undergoing chronic HD treatment for at least 3 months, in the Yaounde University Teaching Hospital dialysis unit. Lung ultrasonography and clinical examinations were performed immediately before dialysis, and 30 minutes after dialysis. Differences between clinical and ultrasound variables before and after dialysis were measured to assess the effects of dialysis. Association between categorical variables was assessed with the Chi-squared test or Fischer test, and Rho’s Spearman coefficient for quantitative variables. Results: There was a reduction in the median of B-lines score after dialysis [12 (7 - 26) versus 8 (5 - 13)], clinical score [2 (1 - 3) versus 0 (-1 - 2)], mean of systolic blood pressure (164.74 ± 26.50 versus 158.48 ± 27.89), frequency of dyspnoea in patients (32.3% versus 6.5%);and raising of the frequency of cramps in patients (0% versus 19.4%) and all statistically significant (p ≤ 0.031). B-lines score before and after dialysis was associated with dyspnoea and raised jugular venous pressure (p Conclusion: Lung ultrasound for the detection of B-lines reflects the variation of extracellular volume during dialysis and can even capture pulmonary oedema at a pre-clinical stage. It is then a reliable and sensible method for assessing extravascular lung water and thus hydration status of haemodialysis patients. It could constitute a better alternative for an objective and accurate definition of dry weight, specifically in the African and Cameroonian context, with its assets being low cost, availability, and easiness to perform in a large population of HD patients. We, therefore, recommend further multicentric studies in order to design a standardized protocol of ultrasound follow-up for all chronic HD patients’ hydration status assessments.展开更多
