Abstract

Complex urological anomalies often require continued care as patients reach adulthood. Adequate transition for adolescents with ongoing urological care needs is critical to allow for seamless care in adult hospitals. Studies have shown that this can lead to improved patient and parental satisfaction, and lower utilisation of unplanned inpatient beds and emergency department visits. There is currently no ESPU-EAU consensus on the adequate mechanism and very few individual papers examining the role of urological transition for these patients in a European setting. This study aimed to identify current practice patterns in paediatric urologists providing adolescent/transitional care, to assess their opinions towards formal transition and to look for variations in care. This has implications for long-term patient health and specialist care. An 18-item cross-sectional survey was compiled and pre-approved through the EAU-EWPU and ESPU board offices prior to dissemination to all registered ordinary members affiliated with the ESPU. This was created using a mini-Delphi method through the EWPU research meetings to provide current semi-quantitative data relating to current opinions and attitudes of this cohort. A total of 172 respondents (55% paediatric general surgery; 45% urology) across 28 countries completed the survey. The majority of respondents were in practice >10 years and spent >80% time in paediatric urology. There was no formal transition process according to 50% respondents and over half of those that did have less than 1/month, with <10% using validated questionnaires. More than two-thirds respondents continued to provide care after transition, as >70% units had no designated corresponding adult service. Furthermore, 93% paediatric believe a formal transition service to be very important, using a multidisciplinary framework. A pareto chart demonstrated 10 specific conditions to be of most interest in transition to adulthood. This is the first study to assess the requirements of paediatric urologists for adequate transitional care, however due to the nature of the survey's distribution, this was a non-scientific poll based on a convenience sample of respondents. It is critical that dual-trained or adult-trained urologists with a specific interest in paediatric urology work with current paediatric urologists in a multidisciplinary fashion to facilitate early transition based on the adolescent's developmental and biopsychosocial requirements. National urological and paediatric surgical societies need to make transitional urology a priority. The ESPU and EAU should collaboratively consider developing transitional urology guidelines to allow a framework by which this can occur. [Display omitted] [ABSTRACT FROM AUTHOR]

Abstract

Peptide hydrolysate (PH) was produced by deep controllable bioconversion of poultry processing leftovers (broiler necks), by means of a multienzyme composition, containing four commercially available enzyme preparations (Alcalase, Neutrase, Flavourzyme, Protamex). The design of multienzyme composition (MEC) was applied to yield a hydrolysate with adjusted properties, including minimized antigenicity and bitterness. The protein recovery was optimized using Box–Behnken response surface design. The individual and interactive effects of hydrolysis conditions (time, hydromodule and MEC dosage) were studied. The experimental data were analyzed by ANOVA method and a well-predictive, second order polynomial model was developed using multiple regression analysis. Optimal hydrolysis conditions were found to be: hydrolysis time 3 h, hydromodule 2.25 l/kg and dosage of MEC 0.25%. The corresponding predicted value for protein recovery was 75.34%, 2 times higher compared to traditional long-term heating hydrolysis. The PH obtained is a low allergenic product with high antioxidant capacity. [ABSTRACT FROM AUTHOR]

Abstract

In this work, we performed a detailed evaluation of the evolution of the oligopeptide fractions in samples of Parmigiano-Reggiano cheese from the curd up to 24 mo of aging. The samples were taken from wheels produced the same day, in the same factory, from the same milk, during the same caseification process, thus simplifying the natural variability of a whey-based starter fermentation. This unique and homogeneous sampling plan, never reported before in the literature, provided a detailed study of the peptides produced by enzymatic events during Parmigiano-Reggiano aging. Given the large dimensions of the 35-kg wheels of Parmigiano-Reggiano, samples were taken from both the internal and external parts of the cheese, to evidence eventual differences in the oligopeptide composition of the different parts. Fifty-seven peptides were considered, being among the most abundant during at least one of the periods of ripening considered, and their semiquantification indicated that the peptide fraction of Parmigiano-Reggiano cheese constantly evolves during the aging period. Five trends in its evolution were outlined, which could be clearly correlated to the enzymatic activities present in the cheese, making it possible to discriminate cheeses according to their aging time. Several known bioactive peptides were also found to be present in Parmigiano-Reggiano cheese samples, and for the first time, the age at which they are most abundant has been identified. Aged cheeses have been shown to be dominated by nonproteolytic aminoacyl derivatives, a new class of peptide-like molecules recently reported. Finally, the changing peptide pattern may be related to the changing enzymatic activities occurring inside the cheeses during the aging period, which, in turn, are also related to the microbiological composition.
