Background: Osteoporosis (OP) is a metabolic bone illness that may complicate celiac disease (CD). It can lead to devastating consequences because of low bone mass and fragility fractures.Purpose: To study the OP prevalence in a group of Brazilian patients with CD and the value of a gluten free diet (GFD).Methods: Retrospective study of celiac female patients from a single University Center followed with bone densitometries. Results from densitometry made at first visit were compared with a second study after a median time of 5 years. During this period, patients were submitted to a GFD according to orientations from special program training. Calcium and vitamin D were prescribed to those patients who did not reach the minimal daily requirement through diet.Results: Forty-one celiac female patients, mean age 46.1 ± 14.8 years, were included. The prevalence of osteopenia at first visit was 56.1% and that of osteoporosis 29.2%. Osteoporosis was associated with longer disease duration (p = 0.01). The second densitometry was performed in a median time of 5 years (range 1 to 13 years) and disclosed 58.9% osteopenia and 28.2% osteoporosis. The GFD improved bone mass, mainly at (of) spine (comparison of T score with p = 0.03 and of bone mass in g/cm

PURPOSE:To compare controlled liver regeneration in rats submitted to 60% hepatic resection having L-arginine supplemented diet, based on weight changes of the regenerated liver, laboratory parameters of liver function and pathological findings. METHODS:Thirty-six rats were divided into two groups, control and L-arginine. The first received standard chow and saline solution by gavage. The second had supplementation with L-arginine. Animals were killed on postoperative period at 24h, 72h and seven days.For analysis of liver regeneration was used Kwon formula for weight, laboratory tests and mitosis. RESULTS:Weight, showed no benefit with L-arginine supplementation; however, intergroup comparison in the first 24h observed positive effect on supplementation (p=0.008). Alkaline phosphatase was increased in arginine group (p<0.04). The number of mitoses showed no difference between the two groups; however, in the first 24 hours, the supplemented group had higher number of mitoses within the groups (p=0.03). CONCLUSION:Supplementation with L-arginine did not show benefits in liver regeneration; however, supplemented group in the first 24 hours showed benefits over 72 hours and seven days of the evaluation by weight gain and number of mitosis.

hemostasis achieved by the groups was similar; however, the use of electrocautery was associated with infections, adhesions at higher grades and elevated liver enzymes.

Background: Ventilator-associated pneumonia (VAP) is one of the most common causes of nosocomial infections and is associated with prolonged hospitalization, increased health care costs, and high mortality of critically ill patients during hospitalization in intensive care units (ICUs). Objective: To characterize and evaluate in vitro and in vivo antimicrobial and anti-biofilm activity of an in-house tracheostomy tube impregnated with chlorhexidine and violet crystal. Methods: The tracheostomy tubes were tested in vitro for their ability to prevent biofilm formation by standard strains of S. aureus, P. aeruginosa, and E. coli, and multidrug-resistant bacteria obtained from clinical cultures: Meticillin-resistant S. aureus (MRSA), and carbapenem-resistant Acinetobacter baumannii, Pseudomonas aeruginosa and Klebsiella pneumoniae. Results: The impregnated tracheostomy tubes demonstrated antimicrobial activity, including for multidrug-resistant bacteria. In this pilot study, 14 patients were evaluated, seven in the chlorhexidine and violet crystal-coated group and seven in the control group. During ventilation, VAP occurred in one patient in the coated group and in three patients in the control group (p=0.28). The biomass in the impregnated tubes did not differ from the control group and no difference was found in the production of sessile cells by the quantitative method, with a median of 15.50 cfu/mL (IQR25-75% 12.00-196.50) and 168.00 cfu/mL ((IQR25-75% 78.50-250.00), respectively. Conclusion: This study provides preliminary evidence to support that antiseptic impregnation of tracheostomy tube provides significant antimicrobial activity.
