Maintaining and preserving an adequate nutritional status is crucial and should be one of the goals of patients with liver or pancreatic disease. Thus, the nutritional status of such patients should be systematically assessed at follow-up. Recently, great progress has been made in this direction, and the relevant pathophysiological mechanisms have been better established. While the spectrum of these diseases is wide, and the mechanisms of the onset of malnutrition are numerous and interrelated, clinical and nutritional manifestations are common. The main consequences include an impaired dietary intake, altered macro and micronutrient metabolism, energy metabolism disturbances, an increase in energy expenditure, nutrient malabsorption, sarcopenia, and osteopathy. In this review, we summarize the factors contributing to malnutritio...

Our aim was to evaluate graft survival and complications in the first year after liver transplantations with livers from older donors. Prospective analysis of 149 consecutive primary liver transplantations performed between 2000 and 2005. Transplantations were divided into two groups according to donor age: group A, <60 yr old (n=102); and group B, ≥60 yr old (n=47). Chronic and acute rejection, vascular complications, and infections were not statistically different between the groups. Anastomotic biliary strictures were similar in the two groups, but non-anastomotic biliary strictures (NABS) were clearly more frequent in the older donor group (17% vs. 4.9%; OR 3.9; p=0.025). NABS with no arterial complication was diagnosed in 10.6% of cases in group B vs. 1% in group A (OR=12; p=0.012). Graft survival in the first year was 86.67% in the younger group of donors and 71.43% in the older group (p<0.05), but patient survival was not different. The use of grafts from donors≥60 yr decreased graft survival after liver transplantation and was related to a higher frequency of non-anastomotic biliary strictures.

In the field of education, in spite of the efforts made to include people with disabilities, the indices of exclusion and inequity persist that make possible quality and equality teaching and learning processes. However, as evidenced by the lack of assistance and attention for the realization of an inclusive education, particularly for the population with hearing disabilities, we can also mention the growing interest in developing projects based on technologies that facilitate the development of skills and improve the processes inside the classroom. Taking into account the above, this article shows a research project that consisted of the design and implementation of a virtual classroom of inclusive learning aimed at students with hearing disabilities.

The multiplier setup is composed of an electrooptic phase modulator followed by a dispersive medium. In contrast to the conventional TSI-based rate-multiplication techniques, the required dispersion is fixed in this method and does not depend on the multiplication factor. Programming the output repetition rate will be then assigned to a preprocessing step where the overall phase of the input pulses is modulated by a phase modulator. Herein, we derive in detail a condition for the required dispersion and introduce an analytical equation for the temporal phase modulation. To validate the derived expressions, proof-of-concept experiments have been carried out and we have achieved high-quality tunable rate multiplication, by factors ranging from 1 to 4, of mode-locked fiber lasers with input repetition rates of 10 and 4.85 GHz, respectively.

The aim of this study was to examine body composition and BMD and their relationship with trauma mechanisms in young and middle-aged patients with femoral neck fracture. Altogether, 185 patients with femoral neck fracture aged 20-69 were included. BMD, body composition and fat-free mass index (FFMI) were determined by dual-X-ray absorptiometry (DXA), and trauma mechanisms were registered. Ninety per cent of the whole study population had a femoral neck BMD below the mean for age. In the young patients (< 50 years), 27% had a Z-score of BMD ≤ -2 SD. More than half of the middle-aged patients (50-69 years) had osteopenia, that is T-score -1 to -2·5, and 35% had osteoporosis, that is T-score < -2·5, at the femoral neck. Patients with low-energy trauma, sport injury or high-energy trauma had a median standardised BMD of 0·702, 0·740 vs. 0·803 g/cm(2) (P = 0·03), and a median FFMI of 15·9, 17·7 vs. 17·5 kg/m(2) (P < 0·001), respectively. FFMI < 10th percentile of an age- and gender-matched reference population was observed in one-third. A majority had low BMD at the femoral neck, and one-third had reduced FFMI (i.e. sarcopenia). Patients with fracture following low-energy trauma had significantly lower femoral neck BMD and FFMI than patients with other trauma mechanisms. DXA examination of both BMD and body composition could be of value especially in those with low-energy trauma.
