A large proportion of patients undergoing surgery have coexisting chronic kidney disease, placing them at greater risk of postoperative morbidity and mortality. The purpose of this review is to review the recent developments in how renal function is estimated, how this relates to surgical outcomes, and how this has been applied clinically. ⋯ Improved accuracy in defining kidney disease will aid clinicians in identifying higher risk patients, and aid earlier diagnosis of acute kidney injury. Further research is required, specifically on the implications of kidney disease in noncardiac surgical patients, and how defining renal function before and after surgery can aid in preventive strategies.

ReviewFeeding the gut: how, when and with what - the metabolic issue.
To review the literature on feeding critically ill patients with special emphasis on the intestine. ⋯ The use of gastric feeding in critical illness is recommended. Successful gastric feeding is indicative of a functional gastrointestinal tract. Pharmacological effects of nutrients are questionable, but supplementation of deficits (glutamine, selenium, etc.) may be in the patient's best interest. A more individualized prescription of nutrition in the critically ill is advocated.

Temporal course of changes in gene expression suggests a cytokine-related mechanism for long-term hippocampal alteration after controlled cortical impact.
Mild traumatic brain injury (mTBI) often has long-term effects on cognitive function and social behavior. Altered gene expression may be predictive of long-term psychological effects of mTBI, even when acute clinical effects are minimal or transient. Controlled cortical impact (CCI), which causes concussive, but nonpenetrant, trauma to underlying (non-cortical) brain, resulting in persistent changes in hippocampal synaptic function, was used as a model of mTBI. ⋯ Ccl2 and Ccl7 transcripts were up-regulated within 24 h after CCI, and their elevation subsided within 1 week of injury. Other transcriptional changes occurred later and were more stable, some persisting for at least 1 month, suggesting that short-term inflammatory responses trigger longer-term alteration in the expression of genes previously associated with injury, aging, and neuronal function in the brain. These transcriptional responses to mTBI may underlie long-term changes in excitatory and inhibitory neuronal imbalance in hippocampus, leading to long-term behavioral consequences of mTBI.

Anti-N-methyl-D-aspartate (NMDA) receptor encephalitis is a recently identified syndrome characterized by psychosis and dysautonomia. Treatment includes resection of the underlying tumor. ⋯ We report a classic presentation of anti-NMDA receptor encephalitis and describe the use of total IV anesthesia with NMDA receptor-sparing drugs. Modest postoperative analgesic requirements, not reported in prior cases, are also described in our report.

Despite many unanswered questions regarding the pathogenesis of interstitial lung disease in systemic sclerosis (SSc-ILD) and the lack of accurate epidemiological risk factors, there have been major advances in the identification and prognostic evaluation of SSc-ILD. The evaluation of disease severity is a multidisciplinary exercise, requiring the integration of pulmonary function tests, high-resolution computed tomography data, and symptomatic severity and these factors all need to be considered in the detection of disease progression. Except in a minority of patients with reversible inflammatory disease, the primary goal of treatment is the prevention of disease progression. ⋯ There is a need to broaden therapeutic approaches with the exploration of rituximab (based on recent pilot data) and antifibrotic agents, shown to have treatment effects in other fibrotic interstitial lung diseases. However, it is also important to avoid the overtreatment of SSc-ILD patients with limited nonprogressive lung involvement. In that setting, an initial policy of nonintervention but meticulous observation ("masterful inactivity with cat-like observation") is often warranted.
