The effect of both the simulated gastrointestinal digestion conditions and the matrix over protein hydrolysis and antioxidant peptides generation was evaluated by comparing an in-house method with COST INFOGEST-based SGD protocols. The in-house protocol was used to digest amaranth protein isolate I (Id1), while the standardized method and a modified version (similar enzyme/substrate ratio than in our lab) were used to digest I and amaranth flour F (Id3 and Fd3, Id2 and Fd2). Protein hydrolysis degree (TNBS method) was similar for the three I digested (about 60%), but lower for F digested (45 and 34% for Fd2 and Fd3, respectively). The five digested obtained presented comparable protein solubility and only small differences in the polypeptide/peptide composition (SDS-PAGE, tricine-SDS-PAGE, gel filtration FPLC), similar antioxidant activity by the ORAC assay (IC50 values between 0.023 and 0.034 mg.mL-1) and some mild differences by the HORAC assay (IC50 values between 1.13 and 1.30 mg.mL-1 for Id1, Fd2, and Fd3; 1.50 mg.mL-1 for Id2; 1.61 mg.mL-1 for Id3). All the FPLC fractions presented high ORAC activity, while only fractions between 0.43 and 3.5 kDa showed HORAC activity (due to peptide concentration). Differences in activity and potency among fractions were registered, especially for F digested. The modification of digestion conditions produced only small differences in the molecular composition but did not affect the proteolysis degree and the antioxidant activity in the case of digested from protein isolate. The presence of other components and changes in the digestion method had an impact on proteolysis, composition and antioxidant activity of flour digested.Acetoin, giving a creamy yogurt aroma and buttery taste, exists in cereal vinegar as an important flavor substance and is mainly produced by the metabolism of Lactobacillus and Acetobacter during multispecies solid-state acetic acid fermentation. However, the impacts of Lactobacillus-Acetobacter interactions on acetoin accumulation and the microbial metabolism during acetic acid fermentation are not completely clear. Here, six strains isolated from vinegar fermentation culture and associated with acetoin metabolism, namely, Lactobacillus reuteri L-0, L. buchneri F2-6, L. brevis 4-20, L. fermentum M10-7, L. casei M1-6 and Acetobacter pasteurianus G3-2, were selected for microbial growth and metabolism analysis in monoculture and coculture fermentations. Lactobacillus sp. and A. selleck inhibitor pasteurianus G3-2 respectively utilized glucose and ethanol preferentially. In monocultures, L. casei M1-6 (183.7 mg/L) and A. pasteurianus G3-2 (121.0 mg/L) showed better acetoin-producing capacity than the others. In the bicultures wi acetate, ethyl lactate, ligustrazine and other important flavoring substances. This work provides a promising strategy for the production of acetoin-rich vinegar through Lactobacillus sp.-A. pasteurianus joint bioaugmentation.This study investigated Indonesian primary health care providers’ knowledge and comfort towards palliative care. A descriptive cross-sectional design was used. From August 2017 to February 2018, the research team approached 70 primary care centres in the Yogyakarta province of Indonesia and invited health care providers to complete the Palliative Care Quiz for Nursing – Indonesia and describe their comfort in caring for terminally ill patients. Data were obtained from 516 health care providers. The mean (±s.d.) score of palliative care knowledge was low (7.8±3.3 of a possible score of 20). Current comfort level in providing palliative care was also low (1.6±2.7 of a possible score of 10). Only 11.3% of palliative care knowledge was explained by respondents understanding of palliative care definition, their education levels and experience in providing palliative care in hospital. However, 82.9% of provider comfort was explained by their experiences for caring for terminally ill patients in primary healthcare centres, palliative care training and years of work experience in primary healthcare centres. Indonesian evidence-based palliative care standards and guidelines must be established with education offered to all providers.Background The addition of pre-exposure prophylaxis (PrEP) for HIV prevention to the Australian Government-subsidised Pharmaceutical Benefits Scheme (PBS) enables any doctor or nurse practitioner to prescribe it and has increased accessibility options. However, understanding of Australian healthcare providers’ (HCP) knowledge and preparedness to prescribe PrEP remains limited.
Semistructured interviews, conducted before PBS listing (October 2016-April 2017), explored PrEP knowledge and prescription experiences of 51 multidisciplinary HCPs involved with the Queensland Pre-Exposure Prophylaxis Demonstration study.
Thematic analysis revealed that participants viewed PrEP as a necessary HIV prevention option, but there was concern about confusing prevention messages and potential risk compensation. Clinical capacity, stigma, cultural norms, rural access and PrEP-associated costs were identified as barriers to access and uptake. Some of these barriers may be addressed by the PBS listing; nonetheless, there was the PBS addressed structural barriers to access, this study highlights the role of nurses and other interdisciplinary healthcare workers in the provision of PrEP in addressing the sociocultural barriers that still affect the access of certain populations to HIV prevention measures. These findings will inform further professional training as PrEP is more widely accessed and requested outside specialist sexual health services. Future work is needed to ensure that the primary healthcare workforce is prepared to provide competent and safe access to PrEP across diverse locations and population groups.This study aimed to understand what barriers exist or choices are made by patients who access regular care for long-term health issues from multiple GPs. This was a qualitative interview study in Western Sydney community settings consisting of semi-structured interviews and inductive thematic analysis. Twenty participants who accessed GP care were interviewed. Sixteen had seen multiple GPs over the previous twelve months and all had seen multiple GPs over preceding years. Participants valued interpersonal continuity of care. Nevertheless, they made decisions to meet their needs by seeing multiple GPs. They considered waiting times, preference for an individual GP based on their consultation style or perception of their particular area of expertise, experiences with reception staff and the practice model of care. Participants were aware that interpersonal continuity of care was considered important by GPs and were reticent to be seen as ‘doctor shoppers’. Therefore, they did not usually disclose that they saw multiple doctors and were unlikely to discuss continuity of care with a GP.
