The objective of this stud）, was to valorize bovine and ovine cheese whey resulting from small and medium cheese manufacture plants, by producing liquid and dr）＂ whey protein concentrates （LWPC and WPC）. The flexibility implemented by batch ultrafiltration （UF） and diafiltration （DF） allowed for the production and ovine WPC with 61 -87% （dry basis）. Diatiltration, performed in of liquid bovine WPC with 43-66% protein contents （dry basis） sequential dilution mode （DFsdm） did not improve significantly the composition of WPC liquid products comparing to the results achieved by conventional UF. However, using DF in volume reduction mode （DFvrm） protein content was increased more than 20% comparing to conventional UF. Ovine products showed higher protein levels （62-84% dry basis） what makes their manufacture attractive. Protein profiles varied with the whey origin and with the concentration process. Using batch DFvrm was possible to obtain richer protein products free of low MW compounds.

Objective: To evaluate the association of socio-demographic and clinical characteristics, and risk factors with occurrence of pressure ulcers in institutionalized elderly people. Method: This cross-sectional, analytical study, in quantitative approach, performed from the database analysis linked to the project “Pressure Ulcer in institutionalized elderly people: Association of incidence with the risk factors to functional and nutritional assessment” developed in six long-stay institutions for the elderly people in João Pessoa. Data were analyzed using the Statistical Package for Social Sciences (SPSS) version 20.0. Associations were made through chi square test and Odds Ratio. Results: The clinical conditions of significant associations with the occurrence of pressure ulcers were the variables neurological disorders (p = 0.011) and visual impairment (p = 0.005). As for risk factors, the most important was fecal incontinence (p Conclusion: The analysis of the associations pointed out problems that require intervention in order to prevent health implications of the elderly people and to minimize the risk and occurrence of this injury.
