Dysnatremia on intensive care unit admission is a stronger risk factor when associated with organ dysfunction.
Dysnatremia present at the time of intensive care unit (ICU) admission is associated with mortality. In this study, we investigated the epidemiology of dysnatremia present on ICU admission and the impact of organ dysfunction on the association between dysnatremia and mortality. We hypothesized that dysnatremia comorbid with organ dysfunction is associated with higher risk of mortality. ⋯ Below 125 and above 150 mmol/L sodium levels at ICU admission are risk factors for higher mortality rates in patients with comorbid organ dysfunction. The effect of dysnatremia on mortality is observed when organ dysfunction is present.

Preventive effects of multisensory rehabilitation on development of cognitive dysfunction following systemic inflammation in aged rats.
Systemic inflammation can trigger transient or longer-lasting cognitive impairments, particularly in elderly patients. However, its pathogenesis has not been sufficiently clarified. In this study, we explored the potential effects of multisensory rehabilitation on cognitive dysfunction following systemic inflammation using an animal model. ⋯ These memory deficits were positively correlated with the levels of both tumor necrosis factor (TNF)-α and interleukin (IL)-1β in the hippocampus. On the other hand, in the LPS-treated ER group, neither cognitive impairment nor an increase in hippocampal levels of both TNF-α and IL-1β was found. These results imply that early rehabilitation (ER) intervention may be effective in preventing cognitive dysfunction following systemic inflammation via its anti-neuroinflammatory effects.

ReviewFluid removal in acute heart failure: diuretics versus devices.
Fluid removal and relief of congestion are central to treatment of acute heart failure. Diuretics have been the decongestive mainstay but their known limitations have led to the exploration of alternative strategies. This review compares diuretics with ultrafiltration and examines the recent evidence evaluating their use. ⋯ Decongestion remains a major challenge in acute heart failure. Although recent studies provide useful data to guide practice, the relatively poor outcomes point to the continued need to identify better strategies for safe and effective decongestion.

Randomized Controlled Trial
A Randomized Controlled Trial of ACE-inhibition for Skeletal Muscle Dysfunction in Chronic Obstructive Pulmonary Disease.
Skeletal muscle impairment is a recognized complication of COPD, predicting mortality in severe disease. Increasing evidence implicates the renin-angiotensin system in control of muscle phenotype. We hypothesized that angiotensin-converting enzyme (ACE) inhibition would improve quadriceps function and exercise performance in COPD. ⋯ This randomized controlled trial found that ACE inhibition, using fosinopril for 3 months, did not improve quadriceps function or exercise performance in patients with COPD with quadriceps weakness.

The prevalence of chronic kidney disease (CKD) is increasing, which presents challenges for both patients and health-care budgets. Although this phenomenon has been attributed to the growth in diabetes, hypertension, and obesity, sleep apnea and nocturnal hypoxemia may also contribute to the pathogenesis of CKD and its progression to kidney failure. Two pathophysiologic mechanisms responsible for CKD are glomerular hyperfiltration and chronic intrarenal hypoxia, resulting in tubulointerstitial injury, the final common pathway to end-stage kidney disease (ESKD). ⋯ Nevertheless, sleep apnea and nocturnal hypoxemia have been associated with loss of kidney function and kidney injury, suggesting that they contribute to the pathogenesis of continued deterioration in kidney function. There are several pathways through which sleep apnea may achieve this, including a direct effect of intrarenal hypoxia and activation of the systemic and renal renin-angiotensin system. Further research is required to better understand these relationships and determine whether specific interventions in patients with sleep apnea have an impact on clinical outcomes, such as reducing the prevalence of CKD and delaying its progression to ESKD.
