Barriers to Goal Attainment in Type Two Diabetics

Type 2 diabetes mellitus (T2DM) is a chronic disease that has reached epidemic proportions worldwide and is a leading cause of death in the United States. Despite the significant risk to morbidity and mortality, the most effective diabetes treatment is still unclear. Implementation of diabetes self-management education (DSME) programs is one method to address the educational needs of patients with T2DM. Barriers to goal attainment need to be more fully addressed if these education programs are to be successful in helping patients make positive behavioral changes. This project implemented shared medical appointments to provide DSME, address barriers to goal attainment, and encourage healthy behavior changes including healthy eating, being active, taking medication, monitoring blood glucose, problem solving, healthy coping, and reducing risks as outlined by the American Association of Diabetes Educators (AADE; Mulcahy et al, 2003). Through use of DSME, these behavior changes, AADE7 (AADE, 2017), and the barriers to goal attainment were addressed. The group process was used during these appointments to allow patients to brainstorm ideas to overcome barriers and support patient individually setting goals. Initial and final self-efficacy scores and HbA1Cs were compared to determine if there was an improvement using this intervention. Both self-efficacy scores and HgA1Cs had statistically significant improvements with implementation of the project. Barriers identified were perceived as iv less following the project. This project provided a new strategy for approaching diabetes education and management. Outcomes from this project supported the continued use of shared medical appointments to provide DSME and development of a template for providers and/or care managers to use for patient education and management

Occurrence of pesticide residues in indoor dust of farmworker households across Europe and Argentina.

Pesticides are widely used as plant protection products (PPPs) in farming systems to preserve crops against pests, weeds, and fungal diseases. Indoor dust can act as a chemical repository revealing occurrence of pesticides in the indoor environment at the time of sampling and the (recent) past. This in turn provides information on the exposure of humans to pesticides in their homes. In the present study, part of the Horizon 2020 funded SPRINT project, the presence of 198 pesticide residues was assessed in 128 indoor dust samples from both conventional and organic farmworker households across Europe, and in Argentina. Mixtures of pesticide residues were found in all dust samples (25-121, min-max; 75, median). Concentrations varied in a wide range (<0.01 ng/g-206 μg/g), with glyphosate and its degradation product AMPA, permethrin, cypermethrin and piperonyl butoxide found in highest levels. Regarding the type of pesticides, insecticides showed significantly higher levels than herbicides and fungicides. Indoor dust samples related to organic farms showed a significantly lower number of residues, total and individual concentrations than those related to conventional farms. Some pesticides found in indoor dust were no longer approved ones (29 %), with acute/chronic hazards to human health (32 %) and with environmental toxicity (21 %)

Collection of human and environmental data on pesticide use in Europe and Argentina: Field study protocol for the SPRINT project

Current farm systems rely on the use of Plant Protection Products (PPP) to secure high productivity and control threats to the quality of the crops. However, PPP use may have considerable impacts on human health and the environment. A study protocol is presented aiming to determine the occurrence and levels of PPP residus in plants (crops), animals (livestock), humans and other non-target species (ecosystem representatives) for exposure modelling and impact assessment. To achieve this, we designed a cross-sectional study to compare conventional and organic farm systems across Europe. Environmental and biological samples were/are being/will be collected during the 2021 growing season, at 10 case study sites in Europe covering a range of climate zones and crops. An additional study site in Argentina will inform the impact of PPP use on growing soybean which is an important European protein-source in animal feed. We will study the impact of PPP mixtures using an integrated risk assessment methodology. The fate of PPP in environmental media (soil, water and air) and in the homes of farmers will be monitored. This will be complemented by biomonitoring to estimate PPP uptake by humans and farm animals (cow, goat, sheep and chicken), and by collection of samples from non-target species (earthworms, fish, aquatic and terrestrial macroinvertebrates, bats, and farm cats). We will use data on PPP residues in environmental and biological matrices to estimate exposures by modelling. These exposure estimates together with health and toxicity data will be used to predict the impact of PPP use on environment, plant, animal and human health. The outcome of this study will then be integrated with socio-economic information leading to an overall assessment used to identify transition pathways towards more sustainable plant protection and inform decision makers, practitioners and other stakeholders regarding farming practices and land use policy

Synergistic protein secretion by mesenchymal stromal cells seeded in 3D scaffolds and circulating leukocytes in physiological flow

Mesenchymal stromal cells (MSC) play an important role in natural wound healing via paracrine and juxtacrine signaling to immune cells. The aim of this study was to identify the signaling factors secreted by preseeded cells in a biomaterial and their interaction with circulating leukocytes, in the presence of physiological biomechanical stimuli exerted by the hemodynamic environment (i.e. strain and shear flow). Electrospun poly(e-caprolactone)-based scaffolds were seeded with human peripheral blood mononuclear cells (PBMC) or MSC. Protein secretion was analyzed under static conditions and cyclic strain. Subsequently, the cross-talk between preseeded cells and circulating leukocytes was addressed by exposing the scaffolds to a suspension of PBMC in static transwells and in pulsatile flow. Our results revealed that PBMC exposed to the scaffold consistently secreted a cocktail of immunomodulatory proteins under all conditions tested. Preseeded MSC, on the other hand, secreted the trophic factors MCP-1, VEGF and bFGF. Furthermore, we observed a synergistic upregulation of CXCL12 gene expression and a synergistic increase in bFGF protein production by preseeded MSC exposed to PBMC in pulsatile flow. These findings identify CXCL12 and bFGF as valuable targets for the development of safe and effective acellular instructive grafts for application in in situ cardiovascular regenerative therapies. © 2014 Elsevier Ltd

'As a clinician, you are not managing lab results, you are managing the patient': how the enactment of malaria at health facilities in Cameroon compares with new WHO guidelines for the use of malaria tests.

In response to widespread overuse of antimalarial drugs, the World Health Organisation changed guidelines in 2010 to restrict the use of antimalarials to parasitologically confirmed malaria cases. Malaria rapid diagnostic tests (RDTs) have been presented as a means to realize the new guidelines, and National Malaria Control Programmes, including that of Cameroon, are developing plans to introduce the tests to replace microscopy or clinical diagnosis at public health facilities across the country. We aimed to understand how malaria tests and antimalarial drugs are currently used as part of social interactions between health workers and patients at public and mission health facilities in Yaoundé and Bamenda and surrounding districts in the Northwest region of Cameroon. In May to June 2010, we held 17 focus group discussions with 146 health workers involved in clinical care from 49 health facilities. Clinicians enacted malaria as a 'juggling' exercise, involving attention to pathophysiology of the patient as well as their desires and medical reputations, utilising tests and medicines for their therapeutic effects as symbols in the process of care. Parasites were rarely mentioned in describing diagnostic decisions. These enactments of malaria contrast with evidence-based guidelines emanating from WHO, which assume the parasite is the central driver of practice. If RDTs are to be taken up in practice, public health practitioners need to pay careful attention to the values and priorities of health workers and patients if they are to work with them to improve diagnosis and treatment of febrile illnesses
