Link Workers in Social Prescribing for Young People work: a case study from Sheffield
Introduction: Social Prescribing has an established recognition regarding the benefits provided to the health-related social needs of adults, but little is known about how the intervention addresses young people’s needs. There is optimism regarding the central role of two core mechanisms that allows social prescribing to be effective, such as the empathetic role of Link Workers and the connection with community resources.
This paper aims to describe the role played by Link Workers working a Social Prescribing intervention targeting young people.
Description: This paper adopts a case study methodology to describe the role of Link Workers addressing young people’s needs and implementing Social Prescribing scheme in Sheffield (UK). Data were collected through semi-structured interviews with four of the seven link workers of one organisation based in Sheffield. Data were analysed through an inductive approach for emerging themes.
Discussion: We provided a description of the profiles and background of Link Workers and described the three models of referral pathways into the intervention. The paper also shows how Link Workers identify young people's needs and how they connect with the community.
Conclusion: Based on the insights and the internationally accepted definition of Social Prescribing, we provide a visual representation of the Social Prescribing model and discuss challenges. The paper highlights lessons learned and future directions regarding the role of Link Workers from the case stud
Budgeting and health technology assessment: First evidence obtained from proposal forms used to submit the adoption of new technology
Objectives: The aim of this study was to benchmark the proposal forms used by a
sample of Italian hospitals to inform the budget process for the adoption of new
technology to understand the relationship with the guidelines provided by the Health
Technology Assessment (HTA) literature.
Methods: A literature review was first undertaken to identify the frameworks developed to
support decision making regarding new technology at a hospital level. A checklist of
criteria drawn up according to five main perspectives (technology, patient, organization,
economics, and level of evidence) has been formalized to review and compare the
collected proposal forms.
Results: The “technology” perspective appears to have been broadly covered. The
“patient” perspective has focused to clinical issues and partially neglects other dimensions
such as patient satisfaction and potential adverse events. The “organization” dimension
has paid little attention to change management. The “economics” dimension has been
broadly covered, even though a sensitivity analysis has not been considered. The “level of
evidence” that is required for submitting the proposal form is little.
Conclusions: The proposal forms used to inform the budget process regarding the
adoption of new technology are accountable for a limited set of dimensions from among
those proposed in literature. Further research is required to understand how to render
technology assessment multidimensional, multidisciplinary, evidence-based, and
accountable at a hospital leve
De-excitation spectroscopy of strongly interacting Rydberg gases
We present experimental results on the controlled de-excitation of Rydberg
states in a cold gas of Rb atoms. The effect of the van der Waals interactions
between the Rydberg atoms is clearly seen in the de-excitation spectrum and
dynamics. Our observations are confirmed by numerical simulations. In
particular, for off-resonant (facilitated) excitation we find that the
de-excitation spectrum reflects the spatial arrangement of the atoms in the
quasi one-dimensional geometry of our experiment. We discuss future
applications of this technique and implications for detection and controlled
dissipation schemes.Comment: 6 pages, 5 figure
Understanding olive oil stability using filtration and high hydrostatic pressure
Veiled extra virgin olive oil (VEVOO) is very attractive on the global market. A study was performed to highlight the role of different amounts of water and microorganisms on the evolution of VEVOO quality during storage, using the selective effects of the application of individual or combined filtration and high hydrostatic pressure (HHP) treatments. Four oil processing trials were carried out in four replicates, resulting in a full factorial design with two independent fixed factors: filtration and HPP treatments. The turbidity of all the olive oil samples was characterized. Furthermore, all the olive oil samples were analysed for legal parameters, volatile organic compounds and phenolic compounds during the storage tests. The microbial contamination in the presence of a high level of water activity (>0.6 Aw) was related to the formation of volatile aroma compounds, which were responsible for the \u201cfusty\u201d sensory defect. Furthermore, high water activity values were related to an increase in the hydrolytic degradation rate of the phenolic compounds. The oil turbidity has to be planned and controlled, starting from adjustment of the water content and application of good manufacturing practices
Filtration scheduling: Quality changes in freshly produced virgin olive oil
Filtration is the most widespread stabilisation operation for extra virgin olive oil, preventing microbial and enzymatic changes. However, during the harvest, the workload of olive mills is at its peak. This results in two approaches to filtration: (i) delays it until after harvesting, increasing the risk of degraded oil quality, and (ii) filters it immediately, increasing the workload. The aim of our experiment is to assess the risk of delaying filtration and establish a safe delay time. Changes in the sensory profile and volatile compound contents were evaluated during 30 days in filtered and unfiltered samples. Significant differences were related to filtration: both turbidity grade and microbial contamination; no differences for the legal parameters were found. Two, contrasting, results were obtained with respect to oil quality: (i) the fusty defect, appearing in less than five days in unfiltered oils, leading to the downgrade of the oil\u2019s commercial category, and (ii) filtration removing some lipoxygenase volatile compounds. Consequently, a fruity attribute was more pronounced in unfiltered samples until day five of storage; it seems that, from this point, the fusty defect masked a fruity attribute. Hence, filtering within a few days strongly reduced the risk of degraded oil quality compared to a delayed filtration
KDR receptor: A key marker defining hematopoietic stem cells
Studies on pluripotent hematopoietic stem cells (HSCs) have been hindered by lack of a positive marker, comparable to the CD34 marker of hematopoietic progenitor cells (HPCs). In human postnatal hematopoietic tissues, 0.1 to 0.5% of CD34+cells expressed vascular endothelial growth factor receptor 2 (VEGFR2, also known as KDR). Pluripotent HSCs were restricted to the CD34+KDR+cell fraction. Conversely, lineage-committed HPCs were in the CD34+KDR-subset. On the basis of limiting dilution analysis, the HSC frequency in the CD34+KDR+fraction was 20 percent in bone marrow (BM) by mouse xenograft assay and 25 to 42 percent in BM, peripheral blood, and cord blood by 12-week long-term culture (LTC) assay. The latter values rose to 53 to 63 percent in LTC supplemented with VEGF and to greater than 95 percent for the cell subfraction resistant to growth factor starvation. Thus, KDR is a positive functional marker defining stem cells and distinguishing them from progenitors
Eucalyptus Globulus L. Essential Oil: Chemical Characterization and Bioactivities Assessment
Eucalyptus is a large genus of tall evergreen plants belonging to the Myrtaceae family, being also one of the most important trees due to its several uses, specially of timber, pulp and essential oil. The demand of Eucalyptus sp. essential oil has
significantly increased as it has been approved as a natural additive. It is widely used in food, flavor, pharmaceutical, and perfumery industries, thanks to its many biological properties, including antibacterial, antifungal, analgesic and antiinflammatory
ones.
Essential oils have been under intensive research, mainly regarding their bioactive properties (antioxidant, fungitoxic, anti-viral, anti-inflammatory, antimicrobial, among others). Owing to these properties they are potentially interesting for diverse
industries including the food industry since one of its main problems concerns pathogenic microorganisms and associated toxins that are responsible for food spoilage.
Although the application of essential oils in the food industry may have some limitations, such as impact on the organoleptic properties and low solubility, different delivery strategies such as nanoencapsulation, active packaging and coatings
are promising technologies that may overcome these issues without compromising nutritional properties in food systems.info:eu-repo/semantics/publishedVersio
Teleconsultation service to improve healthcare in rural areas: acceptance, organizational impact and appropriateness
Background: Nowadays, new organisational strategies should be indentified to improve primary
care and its link with secondary care in terms of efficacy and timeliness of interventions thus
preventing unnecessary hospital accesses and costs saving for the health system. The purpose of
this study is to assess the effects of the use of teleconsultation by general practitioners in rural
areas.
Methods: General practitioners were provided with a teleconsultation service from 2006 to 2008
to obtain a second opinion for cardiac, dermatological and diabetic problems. Access, acceptance,
organisational impact, effectiveness and economics data were collected. Clinical and access data
were systematically entered in a database while acceptance and organisational data were evaluated
through ad hoc questionnaires.
Results: There were 957 teleconsultation contacts which resulted in access to health care services
for 812 symptomatic patients living in 30 rural communities. Through the teleconsultation service,
48 general practitioners improved the appropriateness of primary care and the integration with
secondary care. In fact, the level of concordance between intentions and consultations for cardiac
problems was equal to 9%, in 86% of the cases the service entailed a saving of resources and in 5%
of the cases, it improved the timeliness. 95% of the GPs considered the overall quality positively.
For a future routine use of this service, trust in specialists, duration and workload of
teleconsultations and reimbursement should be taken into account.
Conclusions: Managerial and policy implications emerged mainly related to the support to GPs in
the provision of high quality primary care and decision-making processes in promoting similar
services
