[Correlation of equations for energy expenditure with indirect calorimetry in critically ill patients].

Background: Nutrition in the Intensive Care Unit (ICU) is a cornerstone; however, energy requirements are a controversial issue that has not yet been resolved. Calorimetry is the gold standard for calculating energy expenditure, but it is expensive and not available in all ICU areas. Formulas have been developed to calculate basal energy expenditure (BAE) and make the process easier.

[Ultrasound-guided insertion and the proportion of catheter-associated thrombosis].

Background: Central venous accesses are of great importance in daily medical practice. Insertion into the jugular vein is common due to its accessibility. Catheter-associated venous thrombosis is a relatively common medium-term complication.

[Delta of neutrophil lymphocyte index and mortality in covid-19 disease].

Background: Acute respiratory distress syndrome, due to SARS-CoV-2, is a worldwide health problem. The neutrophil-lymphocyte index allows risk stratification in patients with severe and poor prognostic data, since it reflects the inflammatory state.

Objective: To determine whether the Neutrophil-Lymphocyte Index delta predicts mortality in patients with COVID-19.

Headache, Delirium or Encephalitis? A Case of Residual Mutism Secondary to Anti-NMDA Receptor Encephalitis.

Encephalitis is a heterogeneous syndrome that is diagnosed through clinical assessment and the assistance of laboratory, neuroimaging and electroencephalographic workup. Over the past 10 years, autoimmune encephalitis has been more frequently recognized; however, most reports come from highly specialized hospital settings. Anti-N-methyl-D-aspartate receptor (NDMAR) encephalitis has been associated with paraneoplastic encephalitis syndromes and was first recognized in 2005.

Paraneoplastic opsoclonus-myoclonus syndrome secondary to melanoma metastasis form occult primary cancer.

Introduction: Opsoclonus-myoclonus syndrome (OMS) is an inflammatory neurological disorder, often requiring a prompt medical evaluation. Among the diverse etiologies associated with OMS are autoimmune, infectious, paraneoplastic, and systemic diseases, and drug intoxication.

Clinical Summary: The case of a 36-year-old female with a disabling holocranial headache, sudden loss of consciousness, aggressive behavior, vertigo, and a personal history of somatoform disorder and major depression is presented here.
