ABSTRACT

OBJECTIVE: Patients in rural communities may have limited access to wound care; however, this may be mitigated by using a shared care approach. This study assessed the impact of a remote assessment and monitoring tool in combination with adjunctive continuous topical oxygen therapy (cTOT) in patients with diabetes and hard-to-heal wounds. METHOD: Patients with hard-to-heal wounds (defined as no visible improvement in the previous four weeks) were enrolled to this 12-week pilot study to validate a shared care approach using an Advanced Digital Wound Care Platform-telehealth (ADWCPt) system (eKare Inc., US) coupled with cTOT. Patient and wound assessments were reviewed by the clinician either remotely, via telehealth calls, or at the clinic, and the number of face-to-face clinic visits was recorded. Patient health status scores were captured before and after the study, along with feedback on usability of the remote platform and cTOT device. RESULTS: The wounds in all eight patients studied reduced in size over 12 weeks (mean percentage area reduction 92.0%), and two wounds were completely re-epithelialised. Another wound almost healed (99.2% wound area reduction). Clinical interactions consisted of self-assessments (n=80, 50.0%), video assessments with the clinician (n=27, 16.9%), and face-to-face interactions in clinic (n=53, 33.1%). Operational efficiencies encompassed a 54.0% increase in the number of clinical interactions, whereas clinical time was reduced by 25.8%. Health status scores improved across all eight patients and feedback on the shared approach and cTOT device was favourable. CONCLUSION: A shared care model with ADWCPt coupled with an innovative cTOT device saved time and resources, improving patient access and engagement, along with a marked improvement in the wound healing trajectory.

ABSTRACT

Although there is relative consensus in the literature regarding associations between certain emotion socialization (ES) strategies and youth behavioral health, there is very limited research from a person-centered perspective. To address this gap, the current study examined patterns of ES strategies in families and explored predictors and youth outcomes associated with those patterns. An economically-diverse sample of 229 predominately White mothers and fathers of youth aged 3-12 years was recruited online for a longitudinal study. Latent profile analysis was used to determine the optimal number of family clusters with similar ES profiles. Model fit supported a four-class model, which consisted of an Emotion Coaching profile, characterized by the lowest levels of putatively labeled unsupportive ES practices and the highest levels of putatively labeled supportive ES practices, a Moderate profile characterized by moderate levels of both unsupportive and supportive ES practices, a Limited Engagement profile characterized by low levels of both unsupportive and supportive ES practices, and an Emotion Dismissing profile characterized by the highest levels of unsupportive ES practices and the lowest levels of supportive ES practices. Cross-sectional and longitudinal differences were observed across the ES profiles with regard to demographic and parent emotional competence predictors and youth outcomes. The current study extends the literature on ES by providing evidence on how distinct ES profiles differentially predict youth behavioral health outcomes. Findings also underscore the importance of examining parent emotional competence as a catalyst for adaptive change in the family system.

ABSTRACT

Research shows that daily experiences of awe, curiosity, gratitude, joy, and love can put the average person on a trajectory of growth, success, and positive social connection, and can also prevent those who are suffering from following a downward spiral. Nonetheless, data show that most people are not functioning at optimal capacity. In fact, just 20% of people may be categorized as "flourishing," with the vast majority of people merely "languishing," at risk for mental health issues, or with clinical levels of mental health concerns. Despite the success of the Positive Psychology movement and the proliferation of Positive Psychology Interventions, the field remains in need of high quality studies that test potential mechanisms of change. The Picture This! intervention, informed by Positive Psychology principles, was designed to improve well-being and decrease depressive symptoms in young adults. This paper details the rationale, design, and implementation of a 4-group randomized control trial (RCT) to test the effectiveness of Picture This!. Specific indices of mental health and well-being (e.g., depressive symptoms, gratitude) were measured at baseline and at the conclusion of the intervention along with potential mechanisms of change (i.e., attentional bias, cognitive style), while positive emotion and general well-being were assessed daily over the 21-day intervention period. If successful, this intervention may provide critical behavioral, cognitive, and attentional tools that, once internalized, can be drawn upon for years to come.

ABSTRACT

Identifying and stabilising deterioration in a child with significant clinical compromise is both a challenging and necessary role of the paediatric critical care nurse. Within adult critical care research, high fidelity patient simulation (HFPS) has been shown to positively impact learner outcomes regarding identification and management of a deteriorating patient; however, there is a paucity of evidence examining the use of HFPS in paediatric nursing education. The aim of this study was to investigate the effect of HFPS on nurses' self-efficacy and knowledge for recognising and managing paediatric deterioration. Further, participants' perceptions of the learning experiences specific to the identification and management of a deteriorating child were also explored. Registered nurses working in a tertiary-referral paediatric critical care unit were recruited for this quasi-experimental study. Using a pre-test/post-test control-group design, participants were assigned to one of two learning experiences: HFPS or standard instruction. Following the learning experience, nurses were also invited to participate in semi-structured interviews. 30 nurses participated in the study (control n=15, experiment n=15). Participants in the HFPS intervention were most likely to demonstrate an increase in both perceived self-efficacy (p=<0.01) and knowledge (p=<0.01). No statistically significant change was observed in control group scores. The mean difference in self-efficacy gain score between the two groups was 5.67 score units higher for the experiment group compared to the control. HFPS also yielded higher follow-up knowledge scores (p=0.01) compared to standard instruction. Ten nurses participated in semi-structured interviews. Thematic analysis of the interview data identified four themes: self-awareness, hands-on learning, teamwork, and maximising learning. The results of this study suggest that HFPS can positively influence nurses' self-efficacy and knowledge test scores specific to the recognition and management of paediatric deterioration.

ABSTRACT

OBJECTIVE: The aim of this study was to examine the use of high fidelity patient simulation (HFPS) in paediatric intensive care nursing education through the use of a systematic literature review. METHOD: A systematic search was undertaken in the electronic databases CINAHL (via EBSCOhost), Medline and Pubmed, ClinicalKey, Science Direct and OVID. Electronic searches were supplemented by hand searches of journals, individual article reference lists and the World Wide Web. Main outcome measures were learner outcomes. The search was limited to papers published in English between 2000 and 2015. RESULTS: Eight papers satisfied the inclusion criteria of the review. Studies included in the review ranged from moderate to low on the quality assessment scale. HFPS training was associated with improved short-term learner outcomes of various measures, however this should be considered with the small number of studies examining this topic and the scarcity of high quality randomised studies. CONCLUSIONS: The evidence of improved learner outcomes following HFPS training in paediatric intensive care (PICU) nursing education should be considered together with the quality and methodological limitations of existing research. There was no evidence of negative effects. The direction of research suggests that HFPS is a useful tool in the education of PICU nurses.

ABSTRACT

Infectious and inflammatory diseases have repeatedly shown strong genetic associations within the major histocompatibility complex (MHC); however, the basis for these associations remains elusive. To define host genetic effects on the outcome of a chronic viral infection, we performed genome-wide association analysis in a multiethnic cohort of HIV-1 controllers and progressors, and we analyzed the effects of individual amino acids within the classical human leukocyte antigen (HLA) proteins. We identified >300 genome-wide significant single-nucleotide polymorphisms (SNPs) within the MHC and none elsewhere. Specific amino acids in the HLA-B peptide binding groove, as well as an independent HLA-C effect, explain the SNP associations and reconcile both protective and risk HLA alleles. These results implicate the nature of the HLA-viral peptide interaction as the major factor modulating durable control of HIV infection.

ABSTRACT

Multiple antimicrobial resistance in Staphylococcus aureus can result from mutations leading to reduced susceptibility to Pine oil-based cleaners (PS(RS)) as well as following growth with the non-steroidal anti-inflammatory salicylate. We now define the contributions of the alternative sigma factor (sigB) and staphylococcal accessory regulator (sarA) to these mechanisms. We conclude that sarA plays a more prominent role than sigB in overall intrinsic multiple antimicrobial resistance. Both genes have similar effects on intrinsic vancomycin resistance, and the salicylate-inducible mechanism is not sigB- or sarA-dependent. Furthermore, analyses determined that altered expression of sigB and sarA is not responsible for the salicylate-inducible mechanism, and sarA upregulation is associated with the PS(RS) phenotype.

ABSTRACT

The sarA locus of Staphylococccus aureus regulates the synthesis of over 100 genes on the S. aureus chromosome. We now report the effects of sarA inactivation on intrinsic multidrug resistance expression by S. aureus. In a strain-dependent fashion, sarA::kan mutants of three unrelated strains of S. aureus demonstrated significantly increased susceptibility to five or more of the following substances: the antibiotics ciprofloxacin, fusidic acid, and vancomycin; the DNA-intercalating agent ethidium; and four common household cleaner formulations. In addition, all three sarA::kan mutants demonstrated significantly increased accumulation of ciprofloxacin and one sarA::kan mutant demonstrated increased ethidium accumulation. Our data therefore indicate that sarA plays a role in the intrinsic multidrug resistance mechanism expressed by S. aureus, in part by regulating drug accumulation.
