There is growing evidence of the dietary impact on obesity-induced low-grade chronic inflammation and the associated chronic non-communicable diseases modification. We determined changes in body composition and cardiometabolic and inflammatory status of participants with obesity after 24 weeks of a dietary intervention based on an energy-reduced anti-inflammatory diet and examined the relationship of these changes with changes in the inflammatory potential of the diet. The anthropometric and body composition parameters of 81 participants (average age of 43 years, 74 women) were assessed. Metabolic status was determined using the glycemic and lipid statuses, and the cardiometabolic index and inflammatory status were determined using the concentration of high-sensitivity C-reactive protein (hs-CRP), interleukin 6 (IL-6), and tumor necrosis factor α (TNF-α). The inflammatory potential of the diet was assessed using the Dietary Inflammatory Index (DII^®). Intervention with an anti-inflammatory diet resulted in a significant reduction in body weight and visceral adipose tissue and caused improvements in the participants’ cardiometabolic and inflammatory statuses. The anti-inflammatory diet was shown to be effective regarding obesity management. The study data could advance current scientific knowledge in the field of inflammation and diet, provide guidelines for obesity management, and find its application in routine clinical practice.

This study aimed to examine whether the oral supplementation of vitamins C and E during a seven-day high salt diet (HS; ~14 g salt/day) prevents microvascular endothelial function impairment and changes oxidative status caused by HS diet in 51 (26 women and 25 men) young healthy individuals. Laser Doppler flowmetry measurements demonstrated that skin post-occlusive reactive hyperemia (PORH), and acetylcholine-induced dilation (AChID) were significantly impaired in the HS group, but not in HS+C+E group, while sodium nitroprusside-induced dilation remained unaffected by treatments. Serum oxidative stress markers: Thiobarbituric acid reactive substances (TBARS), 8-iso prostaglandin-F2α, and leukocytes’ intracellular hydrogen peroxide (H₂O₂) production were significantly increased, while ferric-reducing ability of plasma (FRAP) and catalase concentrations were decreased in the HS group. All these parameters remained unaffected by vitamins supplementation. Matrix metalloproteinase 9, antioxidant enzymes Cu/Zn SOD and glutathione peroxidase 1, and leukocytes’ intracellular superoxide production remained unchanged after the protocols in both HS and HS+C+E groups. Importantly, multiple regression analysis revealed that FRAP was the most powerful predictor of AChID, while PORH was strongly predicted by both FRAP and renin-angiotensin system activity. Hereby, we demonstrated that oxidative dis-balance has the pivotal role in HS diet-induced impairment of endothelial and microvascular function in healthy individuals which could be prevented by antioxidative vitamins consumption.

Background. Associated with epidemics of obesity, nonalcoholic fatty liver disease (NAFLD) is becoming the most prevalent liver disease worldwide. The cornerstone of therapy for NAFLD is lifestyle intervention, mainly focused on weight loss. Significant weight loss results from energy‐restricted diets, regardless of macronutrient distribution. An anti‐inflammatory diet was related to lower odds of NAFLD among daily alcohol drinkers and individuals with metabolic syndrome. This study aims to evaluate the effect of an energy‐reduced anti‐inflammatory diet on liver status in younger adults with obesity after a 6‐month follow‐up. Methods. A two‐arm randomized controlled trial surveyed 81 participants’ (mean age, 43 years) anthropometric and body composition changes. Metabolic status was determined with glycaemic and lipid status, inflammatory status with hs‐CRP, IL‐6, and TNF‐α, and liver status with liver enzymes, NAFLD‐FLS, FLI, and FIB‐4 indices. The inflammatory potential of the diet was assessed by the Dietary Inflammatory Index, DII®. Results. Energy‐restricted anti‐inflammatory diet resulted in significant weight loss (−7.1%, p < 0.001), in reducing the visceral adiposity (−22.3%, p < 0.001), metabolic (HOMA‐IR, −15.5%; total cholesterol, −5.3%; LDL‐C, −4.6%; triglycerides, −12.2%), and inflammatory biomarkers (hs‐CRP, −29.5%; IL‐6, −18.2%; TNF‐α, −34.2%), with significant improvement of liver parameters (NAFLD‐FLS, −143.4%; FLI, −14.3%; FIB‐4, −2.5%). Conclusion. The study showed the effectiveness of the anti‐inflammatory diet with significant improvement of liver parameters in younger adults with obesity, which may reinforce the effectiveness of nutrition‐based lifestyle programs, with an anti‐inflammatory dietary approach for the treatment and resolution of NAFLD.

To investigate the changes in the venoarterial carbon-dioxide gradient (V-a Pco2) and its prognostic value for survival of patients with severe sepsis and septic shock. The study was conducted in General Hospital Holy Spirit from January 2004 to December 2007 and included 71 conveniently sampled adult patients (25 women and 46 men), who fulfilled the severe sepsis and septic shock criteria and were followed for a median of 8 days (interquartile range, 12 days). The patients were divided in two groups depending on whether or not they had been mechanically ventilated. Both groups of patients underwent interventions with an aim to achieve hemodynamic stability. Mechanical ventilation was applied in respiratory failure. Venoarterial carbon dioxide gradient was calculated from the difference between the partial pressure of arterial CO2 and the partial pressure of mixed venous CO2, which was measured with a pulmonary arterial Swan-Ganz catheter. The data were analyzed using Kaplan-Meier survival analysis, along with a calculation of the hazard ratios. There was a significant difference between non-ventilated and ventilated patients, with almost 4-fold greater hazard ratio for lethal outcome in ventilated patients (3.85; 95% confidence interval, 1.64-9.03). Furthermore, the pattern of changes of many other variables was also different in these two groups (carbon dioxide-related variables, variables related to acid-base status, mean arterial pressure, systemic vascular resistance, lactate, body mass index, Acute Physiology and Chronic Health Evaluation II, Simplified Acute Physiology II Score, and Sepsis-related Organ Failure Assessment score). Pco2 values (with a cut-off of 0.8 kPa) were a significant predictor of lethal outcome in non-ventilated patients (P = 0.015) but not in ventilated ones (P = 0.270). V-a Pco2 was a significant predictor of fatal outcome only in the non-ventilated group of patients. Ventilated patients are more likely to be admitted with a less favorable clinical status, and other variables seem to have a more important role in their outcome.
