Abstract
Background Dysnatremia is the most common electrolyte disorder in hospitalized patients. Sodium fluctuation level may be a better parameter in dysnatremia management. We aimed to examine the association between sodium fluctuation level during hospitalization and mortality and to evaluate its value in predicting poor prognosis among general hospitalized patients. Methods Data were collected from patients admitted to Peking Union Medical College Hospital. The generalized estimated equation (GEE) was used to examine the relationship between sodium fluctuation level and mortality. Receiver-operating characteristic (ROC) curve analysis was performed to calculate the optimal cutoff value and the area under the ROC curve (AUC). Results Sodium fluctuation level showed a dose-dependent association with increased mortality in general hospitalized patients. After adjusting age, sex, length of hospital stay, and Charlson comorbidity index, the ORs of group G2 to G6 were 5.92 (95% CI 5.16-6.79), 26.45 (95% CI 22.68-30.86), 50.71 (95% CI 41.78-61.55), 104.38 (95% CI 81.57-133.58), and 157.64 (95% CI 112.83-220.24), respectively, p trend <0.001. Both normonatremia and dysnatremia patients on admission had the dose-dependent associations similar to general hospitalized patients. The AUC of sodium fluctuation level was 0.868 (95% CI 0.859-0.877) in general hospitalized patients, with an optimal cutoff point of 7.5 mmol/L, a sensitivity of 76.5% and a specificity of 84.2%. Conclusion We determined that sodium fluctuation level had a dose-dependent association with increased mortality in general hospitalized patients. Sodium fluctuation level could be used to develop a single parameter system in predicting mortality in general hospitalized patients with acceptable accuracy, sensitivity, and specificity.

Plasma sodium during the recovery of renal function in critically ill adult patients: Multicenter prospective cohort study. J Crit Care 2024; 81:154544. [PMID: 38402748 DOI: 10.1016/j.jcrc.2024.154544] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Revised: 01/24/2024] [Accepted: 02/15/2024] [Indexed: 02/27/2024]
Abstract
BACKGROUND Sodium increases during acute kidney injury (AKI) recovery. Both hypernatremia and positive fluid balances are associated with increased mortality. We aimed to evaluate the association between daily fluid balance and daily plasma sodium during the recovery from AKI among critical patients. METHODS Adult patients with AKI were enrolled in four ICUs and followed up for four days or until ICU discharge or hemodialysis initiation. Day zero was the peak day of creatinine. The primary outcome was daily plasma sodium; the main exposure was daily fluid balance. RESULTS 93 patients were included. The median age was 66 years; 68% were male. Plasma sodium increased in 79 patients (85%), and 52% presented hypernatremia. We found no effect of daily fluid balance on plasma sodium (β -0.26, IC95%: -0.63-0.13; p = 0.19). A higher total sodium variation was observed in patients with lower initial plasma sodium (β -0.40, IC95%: -0.53 to -0.27; p < 0.01), higher initial urea (β 0.07, IC95%: 0.04-0.01; p < 0.01), and higher net sodium balance (β 0.002, IC95%: 0.0001-0.01; p = 0.05). CONCLUSIONS The increase in plasma sodium is common during AKI recovery and can only partially be attributed to the water and electrolyte balances. The incidence of hypernatremia in this population of patients is higher than in the general critically ill patient population.

Abstract
Background: Sodium fluctuation is independently associated with clinical deterioration. We developed and validated a prognostic index based on sodium fluctuation for risk stratification and in-hospital monitoring. Methods: This study included 33,323 adult patients hospitalized at a tertiary care hospital in 2014. The first 28,279 hospitalizations were analyzed to develop the model and then the validity of the model was tested using data from 5044 subsequent hospitalizations. We predict in-hospital mortality using age, comorbidity, range of sodium fluctuation, and duration of sodium fluctuation, abbreviated as CARDS. Results: In-hospital mortality was similar in the derivation (0.6%) and validation (0.4%) cohorts. In the derivation cohort, four independent risk factors for mortality were identified using logistic regression: age (66-75, 2 points; >75, 3 points); Charlson comorbidity index (>2, 5 points); range of sodium fluctuation (7-10, 4 points; >10, 10 points); and duration of fluctuation (≤3, 3 points). The AUC was 0.907 (95% CI: 0.885-0.928) in the derivation cohort and 0.932 (95% CI: 0.895-0.970) in the validation cohort. In the derivation cohort, in-hospital mortality was 0.106% in the low-risk group (0-7 points), 1.076% in the intermediate-risk group (8-14 points), and 8.463% in the high-risk group (15-21 points). In the validation cohort, in-hospital mortality was 0.049% in the low-risk group, 1.064% in the intermediate-risk group, and 8.403% in the high-risk group. Conclusions: These results suggest that patients at low, intermediate, and high risk for in-hospital mortality may be identified by CARDS mainly based on sodium fluctuation.

Thalamic Neuron Resilience during Osmotic Demyelination Syndrome (ODS) Is Revealed by Primary Cilium Outgrowth and ADP-ribosylation factor-like protein 13B Labeling in Axon Initial Segment. Int J Mol Sci 2023; 24:16448. [PMID: 38003639 PMCID: PMC10671465 DOI: 10.3390/ijms242216448] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 11/10/2023] [Accepted: 11/13/2023] [Indexed: 11/26/2023] Open
Abstract
A murine osmotic demyelinating syndrome (ODS) model was developed through chronic hyponatremia, induced by desmopressin subcutaneous implants, followed by precipitous sodium restoration. The thalamic ventral posterolateral (VPL) and ventral posteromedial (VPM) relay nuclei were the most demyelinated regions where neuroglial damage could be evidenced without immune response. This report showed that following chronic hyponatremia, 12 h and 48 h time lapses after rebalancing osmolarity, amid the ODS-degraded outskirts, some resilient neuronal cell bodies built up primary cilium and axon hillock regions that extended into axon initial segments (AIS) where ADP-ribosylation factor-like protein 13B (ARL13B)-immunolabeled rod-like shape content was revealed. These AIS-labeled shaft lengths appeared proportional with the distance of neuronal cell bodies away from the ODS damaged epicenter and time lapses after correction of hyponatremia. Fine structure examination verified these neuron abundant transcriptions and translation regions marked by the ARL13B labeling associated with cell neurotubules and their complex cytoskeletal macromolecular architecture. This necessitated energetic transport to organize and restore those AIS away from the damaged ODS core demyelinated zone in the murine model. These labeled structures could substantiate how thalamic neuron resilience occurred as possible steps of a healing course out of ODS.

Abstract
OBJECTIVE To determine the association of dysnatremia in the first postnatal week and risk of acute kidney injury (AKI) and mortality. STUDY DESIGN A secondary analysis of 1979 neonates in the AWAKEN cohort evaluated the association of dysnatremia with (1) AKI in the first postnatal week and (2) mortality, utilizing time-varying Cox proportional hazard models. RESULT Dysnatremia developed in 50.2% of the cohort and was not associated with AKI. Mortality was associated with hyponatremia (HR 2.15, 95% CI 1.07-4.31), hypernatremia (HR 4.23, 95% CI 2.07-8.65), and combined hypo/hypernatremia (HR 6.39, 95% CI 2.01-14.01). In stratified models by AKI-status, hypernatremia and hypo/hypernatremia increased risk of mortality in neonates without AKI. CONCLUSION Dysnatremia within the first postnatal week was associated with increased risk of mortality. Hypernatremia and combined hypo/hypernatremia remained significantly associated with mortality in neonates without AKI. This may reflect fluid strategies kidney injury independent of creatinine and urine-output defined AKI, and/or systemic inflammation.

Abstract
OBJECTIVE To study the serum sodium level and clinical outcome in pediatric nontraumatic coma. METHODS A prospective cohort study was conducted in a tertiary care pediatric intensive care unit (PICU) from September 2015 to June 2016. Children aged < 13 y with nontraumatic coma [modified-Glasgow Coma Scale (m-GCS) score ≤ 8 or fall of ≥ 3 from baseline within 24 h of admission] were included. Children who received intravenous fluids for > 24 h, those with developmental delay, or died within 24 h of admission were excluded. The serum sodium profile (mEq/L) in the first 72 h and clinical outcome [mortality, length of stay in mechanical ventilation, PICU, and hospital] were studied. RESULTS Eighty patients [Died n = 26 and Survived n = 54] were enrolled. Median [interquartile range (IQR)] age and m-GCS were 21 (4-78) mo and 9 (7-11), respectively. The mean [standard deviation (SD)] Pediatric Risk of Mortality-III (PRISM-III) was 17.7 (4). The most common etiology was acute central nervous system (CNS) infections (30%, n = 24) followed by an intracranial bleed (11.3%, n = 9). Mean (Standard error, SE) sodium levels and fluctuation of serum sodium from baseline up to 72 h were similar between nonsurvivors and survivors [140.8 (1.3) vs. 139.6 (0.8), p = 0.421] and [1.2 (0.3) vs. 0.8 (0.2), p = 0.307], respectively. On multivariate analysis, the need for vasoactive therapy was an independent predictor of mortality [adjusted odds ratio = 20.78, 95% CI 4.24-101.85, p = < 0.001, R2 = 0.62]. CONCLUSION Mean serum sodium within normal range and fluctuation of serum sodium of 0.8 to 1.2 mEq/L over 72 h was not associated with poor outcomes in pediatric nontraumatic coma. Vasoactive therapy was an independent predictor of mortality.

Abstract
Aim of our study was to analyze the association between serum sodium (Na) variability and acute kidney injury (AKI) development. We performed a retrospective observational cohort study on the inpatient population admitted to Fondazione Policlinico Universitario A. Gemelli IRCCS between January 1, 2010 and December 31, 2014 with inclusion of adult patients with ≥ 2 Na and ≥ 2 serum creatinine measurements. We included only patients with ≥ 2 Na measurements before AKI development. The outcome of interest was AKI. The exposures of interest were hyponatremia, hypernatremia and Na fluctuations before AKI development. Na variability was evaluated using the coefficient of variation (CV). Multivariable Cox proportional hazards and logistic regression models were fitted to obtain hazard ratios (HRs), odds ratios (ORs) and 95% confidence intervals (CIs) for the association between the exposures of interest and AKI. Overall, 56,961 patients met our inclusion criteria. During 1541 person-years of follow-up AKI occurred in 1450 patients. In multivariable hazard models, patients with pre-existent dysnatremia and those who developed dysnatremia had a higher risk of AKI compared with patients with normonatremia. Logistic models suggested a higher risk for AKI in the 3rd (OR 1.41, 95% CI 1.18, 1.70, p < 0.001) and 4th (OR 1.53, 95% CI 1.24, 1.91, p < 0.001) highest quartiles of Na CV with a significant linear trend across quartiles (p trend < 0.001). This association was also independent from Na highest and lowest peak value. Dysnatremia is a common condition and is positive associated with AKI development. Furthermore, high Na variability might be considered an independent early indicator for kidney injury development.

Abstract
Objective Hyponatremia associated with cerebrospinal fluid (CSF) drainage is primarily limited to pediatric patients. Only 1 case in an adult, after pituitary surgery, has been described. We present the first adult case, to our knowledge, of lumbar CSF drainage associated with the syndrome of inappropriate antidiuretic hormone (SIADH) in a patient with a traumatic basilar skull fracture. Methods Serum and urine samples were evaluated for hyponatremia. Computed tomography and magnetic resonance imaging were performed to evaluate the fractures. Results A 31-year-old woman was hospitalized with traumatic facial and skull base fractures and managed conservatively. Four days into her hospital stay, she underwent lumbar CSF drainage for 6 days to treat a CSF leak. On examination, the patient remained hemodynamically stable and euvolemic. Sodium levels decreased from 142 to 136 mmol/L (normal, 135-146 mmol/L) on the day before and after lumbar drain placement, respectively, down to a nadir of 124 mmol/L over 3 subsequent days. Serum osmolality was 260 mOsm/kg (275-295 mOsm/kg); urine osmolality, 482 mOsm/kg; urine Na, 175 mmol/L; and thyroid-stimulating hormone, 4.0 μIU/mL (0.3-4.7 μIU/mL). The patient received treatment with sodium tablets, fluid restriction, and hypertonic saline for a diagnosis of SIADH. Sodium levels normalized from 131 to 136 mmol/L within 16 hours after lumbar drain removal. Conclusion This case illustrated a temporal association of SIADH with CSF drainage in an adult. Although this could be coincidental because a basilar skull fracture can lead to SIADH, it raises the possibility that CSF lumbar drainage contributed to the patient’s SIADH.

Abstract
Background/Aims: Aim of our study was to describe the association between natremia (Na) fluctuation and hospital mortality in a general population admitted to a tertiary medical center. Methods: We performed a retrospective observational cohort study on the patient population admitted to the Fondazione Policlinico A. Gemelli IRCCS Hospital between January 2010 and December 2014 with inclusion of adult patients with at least 2 Na values available and with a normonatremic condition at hospital admission. Patients were categorized according to all Na values recorded during hospital stay in the following groups: normonatremia, hyponatremia, hypernatremia, and mixed dysnatremia. The difference between the highest or the lowest Na value reached during hospital stay and the Na value read at hospital admission was used to identify the maximum Na fluctuation. Cox proportional hazards models were used to estimate hazard ratios (HRs) for in-hospital death in the groups with dysnatremias and across quartiles of Na fluctuation. Covariates assessed were age, sex, highest and lowest Na level, Charlson/Deyo score, cardiovascular diseases, cerebrovascular diseases, dementia, congestive heart failure, severe kidney disease, estimated glomerular filtration rate, and number of Na measurements during hospital stay. Results: 46,634 admissions matched inclusion criteria. Incident dysnatremia was independently associated with in-hospital mortality (hyponatremia: HR 3.11, 95% CI 2.53, 3.84, p < 0.001; hypernatremia: HR 5.12, 95% CI 3.94, 6.65, p < 0.001; mixed-dysnatremia: HR 4.94, 95% CI 3.08, 7.92, p < 0.001). We found a higher risk of in-hospital death by linear increase of quartile of Na fluctuation (p trend <0.001) irrespective of severity of dysnatremia (HR 2.34, 95% CI 1.55, 3.54, p < 0.001, for the highest quartile of Na fluctuation compared with the lowest). Conclusions: Incident dysnatremia is associated with higher hospital mortality. Fluctuation of Na during hospital stay is a prognostic marker for hospital death independent of dysnatremia severity.

Abstract
PURPOSE Serum sodium derangement is the most common electrolyte disturbance among patients admitted to intensive care. This study aims to validate the association between dysnatremia and serum sodium fluctuation with mortality in surgical intensive care patients. METHOD We performed a retrospective analysis of the Medical Information Mart for Intensive Care II database. Dysnatremia was defined as a sodium concentration outside physiologic range (135-145mmol/L) and subjects were categorized by severity of dysnatremia and sodium fluctuation. Univariate and multivariable logistic regressions were used to test for associations between sodium fluctuations and mortality. RESULTS We identified 8600 subjects, 39% of whom were female, with a median age of 66years for analysis. Subjects with dysnatremia were more likely to be dead at 28 days (17% vs 7%; P<.001). There was a significant association between sodium fluctuation and mortality at 28 days (adjusted odds ratio per 1mmol/L change, 1.10 [95% confidence interval, 1.08-1.12; P<.001]), even in patients who remained normotremic during their intensive care unit stay (1.12 [95% confidence interval, 1.09-1.16; P<.001]) CONCLUSIONS: This observational study validates previous findings of an association between serum sodium fluctuations and mortality in surgical intensive care patients. This association was also present in subjects who remained normonatremic throughout their intensive care unit admission.

Abstract
UNLABELLED Dysnatremias (DN) are common electrolyte disturbances in cardiac critical illness and are known risk factors for adverse outcomes in certain populations. Little information exists on DN in children with cardiac disease admitted to the cardiac intensive care unit (CICU) after undergoing cardiac surgery, either corrective or palliative. The aim was to determine the incidence and adverse outcomes associated with DN in neonates and infants undergoing cardiac surgery. Retrospective cohort and single center study performed at Children's Hospital Colorado from May 2013 to May 2014, in children under 1 year old admitted to the CICU after undergoing surgery for congenital or acquired cardiac disease. 183 subjects were analyzed. EXCLUSIONS subjects that demonstrated DN before surgery. Serum sodium levels were recorded for the first 72 h post-operatively. DN was present in 54% of the subjects (98/183): hypernatremia in 60 (33%), hyponatremia in 38 (21%). Multivariate analysis revealed that mild hypernatremia (146-150 mmol/dl) and moderate hypernatremia (151-155 mmol/dl) were associated with longer hospital length of stay (LOS, p < 0.05) and ventilation times (p < 0.05). No association was shown between mild/moderate hyponatremia (125-134 mmol/dl) with either outcome. Hours to DN were significantly lower in hypernatremic (median = 5.8 h) than hyponatremic (median = 43.8 h) patients (p < 0.001). Children younger than 30 days presented DN at an earlier stage than those 31 days-1 year old (median +2.2 vs. 17.3 h). No associations present between DN and the class of diuretic (loop vs. thiazide) administered, or the route of administration (intravenous bolus vs. constant infusion). Total median sodium bicarbonate administration was associated with hypernatremia, as was exposure to vasopressin within the first 72 h post-operatively. Dysnatremias are common in the early post-operative period in neonates and infants undergoing cardiac surgery. Mild to moderate hypernatremia, but not hyponatremia, is associated with longer LOS and longer ventilation time in infants undergoing cardiovascular surgery. Hypernatremia is also associated with younger infants, a higher surgical complexity, administration of bicarbonate and exposure to vasopressin. Diuretic type or interval timing of intravenous delivery did not demonstrate any effect. Prospective studies are needed in this population, in order to determine how DN, particularly hypernatremia, contributes to adverse outcomes, whether this association is independent of illness severity, and what may be safe treatments and interventions for these disorders.
