Background: Psychological sequelae of chronic obstructive pulmonary disease (COPD) may influence the patients' functional status independently of disease severity. The presence of depression among several phenotypes of COPD is not clearly understood. Aim: The objective was to find out the actual rates of depression in both basic clinical phenotypes of COPD. Methods and material: Multicomponent assessment of 38 consecutive patients (6 females, 66.7 ± 7.6 years) with stable COPD (GOLD categories A 1, B21, CO, D 16) in an out-patient department of a university hospital (non-interventional cross-sectional Complexity of COPD Study). Results: Twenty-seven patients had bronchitic and 11 subjects suffered from non-bronchitic phenotypes of COPD (post-ipratropium and salbutamol FEV1 57.7 %). The bronchitic phenotype was associated with lower levels of depressive symptoms (Beck scale 5.1 ± 3.0, Zung scale 50.2 ±10.9) than the non-bronchitic subtype of COPD (Beck scale 8.3 ± 3.4, Zung scale 57.5 ± 7.4). However, the difference reached statistical significance only in Beck's questionnaire (p = 0.013; Mann-Whitney U-test). In all the other parameters (BMI, FFMI, education level, inhalation risk, 6-MWD, exercise desaturation, mMRC dyspnea, Celli's BODE, Puhan's BODE, ADO, CAT, all SGRQ domains, arterial blood gases, ECG heart rate), there were no differences between the two basic phenotypes. Conclusion: The non-bronchitic phenotype of COPD was associated with more depression complaints than the bronchitic one. This difference was not apparent in terms of quality of life, prognostic indices and numerous other variables describing the course of COPD. Source

New role and rennaisance of branched chain aminoacids in intensive care The branched chain amino acids valine, leucine and isoleucine are essential nutrients with more than nutritional effects. They are important mediators and structural components in proteosynthesis and they regulate hormonal functions. Leucine is a precursor in cholesterol synthesis and as such plays an important role in muscle tissue growth and in sarcopenia suppression. Older and recent data are reviewed and support wider utilization of branched chain amino acids in intensive care. Source

The review article covers specific methods of artificial nutrition in current advances in intensive care. This area of care is somewhat specific, and indications for pharmaconutrients are different from classical artificial nutrition. The pharmaconutrients of amino acid and polyenoic fatty acid groups are described. The components of nutritional pharmacology, based on exceedingly high doses of pure nutritional substrates, are a useful and safe means of modifying selected mechanisms, such as fluidocoagulation, inflammatory reactions or vasomotorics.

Summary: Current model of metabolic and nutritional disorders management utilizes modern techniques that promote some of the nutritional techniques to pharmacoteherapy. This approach is demonstrated on an example of multiple organ failure and systemic inflammatory reaction managed with pharmacologically active nutritional substrates, such as arginine, glutamine, taurine, threonine and cysteine. Treatment of sarcopenia in older age is also discussed. Personalized nourishment as a component part of a wider term personalized medicine represents a new approach that requires recognition of individual differences in human genome and its expression. However, this approach also requires a change of attitude towards laboratory diagnostics and clinical practice, with patients and clinical prediction as the focal point. From this perspective, there is a need to replace current traditional laboratory tests with a new system that utilizes molecular biology and bioinformatics. Source

The role of the bowel function in intensive care has for a long time been underestimated, but the metabolic or barrier function failure can have potentially fatal consequences. This review summarises the major causes and effects of functional and metabolic bowel damage with emphasis on critical care. The dominant factors are intestinal hypoperfusion consequent to systemic hypotension, restriction of blood flow in the mesenteric area due to partial obstruction of the mesenteric arteries, inflammation, toxicity of xenobiotics to enterocytes, infectious agents, lack of nutrients, ionizing radiation and mechanical bowel damage. The necessary tests for possible comorbidities, which further deteriorate bowel function, and specific intestinal laboratory examinations are described. These include saccharide absorption tests and determination of D-lactate or intestinal fatty acid binding protein. The basic options for nutritional improvement of the intestinal function are listed, namely minimal enteral nutrition, the current recommendations for prevention of intestinal damage in critical care and the cholinergic vagal stimulation concept using choline precursors. Adherence to such regimens facilitates restoration or maintenance of the gut function. Source
