Effects of an Interactive, Computer-Based, Abstinence Education Curriculum on Selected Student Outcomes

A variety of environmental health issues occur within homes along the US/Mexico border region. Individuals living in this region are often not aware that specific issues, including pesticide safety, occur in their homes and may not understand the potential adverse effects of pesticide use on their families’ health. The Environmental Health/Home Safety Education Project created by the Southern Area Health Education Center at New Mexico State University, utilizes promotoras (community health workers) to educate clients on pesticide safety issues. Data from 367 pre/post tests and home assessments were collected from 2002-2005. The data were analyzed to detect changes in clients’ knowledge or behavior as they related to protecting themselves and their families against unsafe pesticide use and storage. Statistically significant changes occurred with both knowledge and behavior in regards to safe pesticide use. Through this culturally appropriate intervention, the promotoras provide practical information allowing clients to make their homes safer

Efficacy of off-label topical treatments for the management of androgenetic alopecia: a review

Androgenetic alopecia (AGA) is characterized by non-scarring follicle miniaturization. Despite the success of approved therapies, commonly reported side effects and the need for continual use has led to the investigation of alternative therapies. The aim of this paper is to critically review the success of off-label, topical monotherapies for treatment of AGA in men. A literature search was conducted to obtain randomized, controlled and blinded studies that investigated off-label, topical, monotherapies in male patients. Hair density, hair diameter and hair growth were used to evaluate treatment success. Fourteen off-label topical therapies were investigated among the 16 studies that met inclusion criteria. Nine off-label therapies were reported to produce a significantly greater improvement in hair restoration parameters (e.g. mean change from hair count and hair diameter) as compared to placebo (p < 0.05 for all treatments). In two studies, procyanidin oligomers exhibited greater efficacy over vehicle with response to mean change in hair density (hairs/cm2) (ps < 0.0001 at Week 24). In conclusion, prostaglandin analogs and polyphenols, such as latanoprost and procyanidin oligomers, can improve hair restoration parameters in male AGA patients, possibly through targeting mechanisms proposed in the etiology of AGA. The current evidence suggests short-term (24 weeks) use may provide benefit for hair loss patients; however, long-term efficacy and safety data are required

Tinea capitis in children: a systematic review of management

Background Tinea capitis is the most common cutaneous fungal infection in children. Objectives This review aims to evaluate the differences that exist between medications for the treatment of tinea capitis, to determine whether there are any significant adverse effects associated and to define the usefulness of sample collection methods. Methods We conducted a systematic literature search of available papers using the databases PubMed, OVID, Cochrane Libraries and ClinicalTrials.gov. Twenty‐one RCTs and 17 CTs were found. Results Among the different antifungal therapies (oral and combination thereof), continuous itraconazole and terbinafine had the highest mycological cure rates (79% and 81%, respectively), griseofulvin and terbinafine had the highest clinical cure rates (46% and 58%, respectively) and griseofulvin and terbinafine had the highest complete cure rate (72% and 92%, respectively). Griseofulvin more effectively treated Microsporum infections; terbinafine and itraconazole more effectively cured Trichophyton infections. Only 1.0% of children had to discontinue medication based on adverse events. T. tonsurans was the most common organism found in North America, and hairbrush collection method is the most efficient method of sample collection. Additionally, using a hairbrush, toothbrush or cotton swab to identify the infecting organism(s) is the least invasive and most efficient method of tinea capitis sample collection in children. Conclusions Current dosing regimens of reported drugs are effective and safe for use in tinea capitis in children

Implementing resilience engineering for healthcare quality improvement using the CARE model: a feasibility study protocol

BACKGROUND: Resilience engineering (RE) is an emerging perspective on safety in complex adaptive systems that emphasises how outcomes emerge from the complexity of the clinical environment. Complexity creates the need for flexible adaptation to achieve outcomes. RE focuses on understanding the nature of adaptations, learning from success and increasing adaptive capacity. Although the philosophy is clear, progress in applying the ideas to quality improvement has been slow. The aim of this study is to test the feasibility of translating RE concepts into practical methods to improve quality by designing, implementing and evaluating interventions based on RE theory. The CARE model operationalises the key concepts and their relationships to guide the empirical investigation. METHODS: The settings are the Emergency Department and the Older Person's Unit in a large London teaching hospital. Phases 1 and 2 of our work, leading to the development of interventions to improve the quality of care, are described in this paper. Ethical approval has been granted for these phases. Phase 1 will use ethnographic methods, including observation of work practices and interviews with staff, to understand adaptations and outcomes. The findings will be used to collaboratively design, with clinical staff in interactive design workshops, interventions to improve the quality of care. The evaluation phase will be designed and submitted for ethical approval when the outcomes of phases 1 and 2 are known. DISCUSSION: Study outcomes will be knowledge about the feasibility of applying RE to improve quality, the development of RE theory and a validated model of resilience in clinical work which can be used to guide other applications. Tools, methods and practical guidance for practitioners will also be produced, as well as specific knowledge of the potential effectiveness of the implemented interventions in emergency and older people's care. Further studies to test the application of RE at a larger scale will be required, including studies of other healthcare settings, organisational contexts and different interventions

Postgraduate education for Chinese medicine practitioners: a Hong Kong perspective

&lt;b&gt;Background&lt;/b&gt; Despite Hong Kong government's official commitment to the development of traditional Chinese medicine (TCM) over the last ten years, there appears to have been limited progress in public sector initiated career development and postgraduate training (PGT) for public university trained TCM practitioners. Instead, the private TCM sector is expected to play a major role in nurturing the next generation of TCM practitioners. In the present study we evaluated TCM graduates' perspectives on their career prospects and their views regarding PGT.&lt;p&gt;&lt;/p&gt; &lt;b&gt;Method&lt;/b&gt; Three focus group discussions with 19 local TCM graduates who had worked full time in a clinical setting for fewer than 5 years. &lt;p&gt;&lt;/p&gt; &lt;b&gt;Results&lt;/b&gt; Graduates were generally uncertain about how to develop their career pathways in Hong Kong with few postgraduate development opportunities; because of this some were planning to leave the profession altogether. Despite their expressed needs, they were dissatisfied with the current quality of local PGT and suggested various ways for improvement including supervised practice-based learning, competency-based training, and accreditation of training with trainee involvement in design and evaluation. In addition they identified educational needs beyond TCM, in particular a better understanding of western medicine and team working so that primary care provision might be more integrated in the future. &lt;p&gt;&lt;/p&gt; &lt;b&gt;Conclusion&lt;/b&gt; TCM graduates in Hong Kong feel let down by the lack of public PGT opportunities which is hindering career development. To develop a new generation of TCM practitioners with the capacity to provide quality and comprehensive care, a stronger role for the government, including sufficient public funding, in promoting TCM graduates' careers and training development is suggested. Recent British and Australian experiences in prevocational western medicine training reform may serve as a source of references when relevant program for TCM graduates is planned in the futur

What is the value and impact of quality and safety teams? A scoping review

<p>Abstract</p> <p>Background</p> <p>The purpose of this study was to conduct a scoping review of the literature about the establishment and impact of quality and safety team initiatives in acute care.</p> <p>Methods</p> <p>Studies were identified through electronic searches of Medline, Embase, CINAHL, PsycINFO, ABI Inform, Cochrane databases. Grey literature and bibliographies were also searched. Qualitative or quantitative studies that occurred in acute care, describing how quality and safety teams were established or implemented, the impact of teams, or the barriers and/or facilitators of teams were included. Two reviewers independently extracted data on study design, sample, interventions, and outcomes. Quality assessment of full text articles was done independently by two reviewers. Studies were categorized according to dimensions of quality.</p> <p>Results</p> <p>Of 6,674 articles identified, 99 were included in the study. The heterogeneity of studies and results reported precluded quantitative data analyses. Findings revealed limited information about attributes of successful and unsuccessful team initiatives, barriers and facilitators to team initiatives, unique or combined contribution of selected interventions, or how to effectively establish these teams.</p> <p>Conclusions</p> <p>Not unlike systematic reviews of quality improvement collaboratives, this broad review revealed that while teams reported a number of positive results, there are many methodological issues. This study is unique in utilizing traditional quality assessment and more novel methods of quality assessment and reporting of results (SQUIRE) to appraise studies. Rigorous design, evaluation, and reporting of quality and safety team initiatives are required.</p

Investigating the cell biological mechanisms regulated by the cellular prion protein

Transmissible spongiform encephalopathies (TSEs) are rare, uniformly fatal neurodegenerative disorders that can affect many mammalian species, including humans. A hallmark of these diseases is the conversion of cellular prion protein (PrPC) into an abnormally folded form. This misfolded PrPC is infectious, since it can provide a template for pathogenic conversion of PrPC in a new host. In addition to any toxicity of the misfolded protein, loss of normal PrPC function could be involved in the neurodegenerative processes. However, the physiological role of PrPC is still poorly understood and this project has aimed to address that lack of knowledge. Out of the many putative functions ascribed to PrPC, the most commonly proposed is that it protects cells from stress. In contrast, I have found that stable transfection of the prion protein gene into SH-SY5Y neuroblastoma cells increases cell death in response to serum removal from the culture medium. Following treatment with several chemical toxins, two out of four stably transfected clones did, generally, display greater viability than untransfected cells that do not express detectable levels of PrPC. However, knockdown of PrPC expression by RNA interference had no effect on this stress resistance, indicating that it may not have been mediated directly by PrPC. Given the lack of robust stress protection afforded by PrPC transfection, proteomic analyses of the cells were carried out to identify alternative processes that were perturbed as a result of PrPC expression. The results obtained suggested roles for PrPC in cytoskeletal organisation and cell cycle regulation. Various proteins involved in cytoskeletal organisation were confirmed by western blotting to be differentially expressed in some or all of the stably transfected clones. Additionally, the expression changes to proteins involved in cell cycle regulation resulted in slower proliferation of the clones compared with untransfected cells, a difference that was reduced following RNA interference-mediated knockdown of PrPC. Taken together, these data suggested that specific growth factor-activated pathways were differentially regulated in the stably transfected clones. One candidate pathway was nerve growth factor (NGF) signalling, which promotes neuronal survival and differentiation as well as regulating various processes outside of the nervous system. PrPC-transfection resulted in altered expression of receptors for NGF, suggesting that the stably transfected clones were, indeed, responding differently to NGF stimulation. However, the molecular mechanism responsible for these expression changes remains to be determined, since co-immunoprecipitation experiments did not identify any physical interactions between PrPC and the NGF receptors. Nonetheless, a role for PrPC in modulating NGF signalling has the potential to explain many of the diverse phenotypic observations in PrPC-null mice and might indicate that loss of PrPC function is an important part of TSE pathogenesis
