Patient-shared knowledge and information in clinical decision-making : an international survey of the perspectives and experiences of naturopathic practitioners
Introduction Most knowledge translation models pay relatively little attention to patient-held knowledge and are largely based on the premise that researchers and clinicians hold all valuable knowledge, and patients are passive recipients of such knowledge. Counter to this clinician- and researcher-centred lens is a growing interest and awareness of patients as experts in their health. While naturopathic medicine is described and experienced as a patient-centred system of traditional medicine, the position of patient-held knowledge is unclear particularly when considered alongside their use of other more objective forms of knowledge such as research evidence. Methods This international online cross-sectional survey aimed to explore naturopathic practitioners’ perceptions of the value and contribution of patient-shared knowledge and information within the context of naturopathic clinical consultations. Results The survey was completed by 453 naturopathic practitioners (response rate: 74.3%). Approximately two-thirds (68.2%) of respondents reported using information shared by the patient. Most rated ‘information provided by the patient’ as either ‘extremely important’ (60.7%) or ‘very important’ (31.4%) to patients. Highest levels of trust were reported for information provided by the patient (‘completely’: 9.9%; ‘a lot’: 53.6%). Most practitioners indicated they trusted knowledge and information derived from the patient’s personal health history ‘completely’(n=79; 21.8%) or ‘a lot’(n=226; 62.4%) from the patient’s perspective of living with a health condition (‘completely’[n=63, 17.4%]; ‘a lot’[n=224, 61.9%]). Patients were the highest ranked stakeholder group (mean: 1.5) perceived to influence NP use of patient experience of living with a health condition to inform clinical decision-making. Conclusion Researchers and policy makers are increasingly focused on the value of the ‘expert patient’ in clinical decision-making, yet health professionals’ report challenges and, in some cases, resistance to meaningfully engaging with patient-shared knowledge in practice. However, our study has found patient-shared knowledge – inclusive of patient experience of their health condition – is among the knowledge used and trusted by naturopathic practitioners to inform their clinical decision-making. This study both offers insights into the knowledge translation behaviours of an under-researched health profession and provides a novel contribution to the wider aim of adopting patient shared knowledge into clinical care more generally.Publisher PDFPeer reviewe
Prescription Drug Monitoring Program Utilization in Kentucky Community Pharmacies
OBJECTIVE: Identify characteristics of Kentucky community pharmacists and community pharmacists\u27 practice environment associated with utilization of the Kentucky All Schedule Prescription Electronic Reporting Program (KASPER).
METHODS: Surveys were mailed to all 1,018 Kentucky pharmacists with a KASPER account and an additional 1,000 licensed pharmacists without an account. Bivariate analyses examined the association between KASPER utilization and practice type (independent or chain) and practice location (rural or urban). A multivariate Poisson regression model with robust error variance estimated risk ratios (RR) of KASPER utilization by characteristics of pharmacists\u27 practice environment.
RESULTS: Responses were received from 563 pharmacists (response rate 27.9%). Of these, 402 responses from community pharmacists were included in the analyses. A majority of responding pharmacists (84%) indicated they or someone in their pharmacy had requested a patient\u27s controlled substance history since KASPER\u27s inception. Bivariate results showed that pharmacists who practiced in independent pharmacies reported greater KASPER utilization (94%) than pharmacists in chain pharmacies (75%; p
CONCLUSION: Utilization of KASPER differs by community pharmacists\u27 practice environment, predominantly by practice type and location. Understanding characteristics of community pharmacists and community pharmacists\u27 practice environment associated with PDMP use is necessary to remove barriers to access and increase utilization thereby increasing PDMP effectiveness
Rural Appalachian Women Will Suffer Disproportionately if Attempts to Further Restrict Emergency Contraception are Successful
The removal of federal abortion protection has incited fear that restrictions on contraception may be next. Many states now imposing abortion restrictions and bans are in the South and Appalachian Regions of the U.S., where rates of unplanned pregnancy and poor health outcomes are already disproportionately high. Numerous studies have documented variable access to levonorgestrel EC (LNG EC) in community pharmacies, with particularly low rates of access at independent pharmacies that are more likely to be located in rural communities than chain pharmacies. Since the overturn of Roe v. Wade, some large chain pharmacies and online retailers are restricting the purchase of LNG EC, limiting its availability. Some legislators and activists are calling for a ban on EC based on a misunderstanding about its mechanism of action, equating it with abortion. At a time when access to the full range of contraceptive options is more critical than ever, already limited access to LNG EC is worsening. Extensive data on LNG EC availability in 509 pharmacies and 400 health clinics across West Virginia, contextualized with socioeconomic demographics, illustrate existing disparities in LNG EC access

SAMHD1 restricts HIV-1 infection in dendritic cells (DCs) by dNTP depletion, but its expression in DCs and primary CD4+ T-lymphocytes cannot be upregulated by interferons
BACKGROUND: SAMHD1 is an HIV-1 restriction factor in non-dividing monocytes, dendritic cells (DCs), macrophages, and resting CD4(+) T-cells. Acting as a deoxynucleoside triphosphate (dNTP) triphosphohydrolase, SAMHD1 hydrolyzes dNTPs and restricts HIV-1 infection in macrophages and resting CD4(+) T-cells by decreasing the intracellular dNTP pool. However, the intracellular dNTP pool in DCs and its regulation by SAMHD1 remain unclear. SAMHD1 has been reported as a type I interferon (IFN)-inducible protein, but whether type I IFNs upregulate SAMHD1 expression in primary DCs and CD4(+) T-lymphocytes is unknown. RESULTS: Here, we report that SAMHD1 significantly blocked single-cycle and replication-competent HIV-1 infection of DCs by decreasing the intracellular dNTP pool and thereby limiting the accumulation of HIV-1 late reverse transcription products. Type I IFN treatment did not upregulate endogenous SAMHD1 expression in primary DCs or CD4(+) T-lymphocytes, but did in HEK 293T and HeLa cell lines. When SAMHD1 was over-expressed in these two cell lines to achieve higher levels than that in DCs, no HIV-1 restriction was observed despite partially reducing the intracellular dNTP pool. CONCLUSIONS: Our results suggest that SAMHD1-mediated reduction of the intracellular dNTP pool in DCs is a common mechanism of HIV-1 restriction in myeloid cells. Endogenous expression of SAMHD1 in primary DCs or CD4(+) T-lymphocytes is not upregulated by type I IFNs
The Retroviral Restriction Ability of SAMHD1, but Not Its Deoxynucleotide Triphosphohydrolase Activity, Is Regulated by Phosphorylation
SummarySAMHD1 is a cellular enzyme that depletes intracellular deoxynucleoside triphosphates (dNTPs) and inhibits the ability of retroviruses, notably HIV-1, to infect myeloid cells. Although SAMHD1 is expressed in both cycling and noncycling cells, the antiviral activity of SAMHD1 is limited to noncycling cells. We determined that SAMHD1 is phosphorylated on residue T592 in cycling cells but that this phosphorylation is lost when cells are in a noncycling state. Reverse genetic experiments revealed that SAMHD1 phosphorylated on residue T592 is unable to block retroviral infection, but this modification does not affect the ability of SAMHD1 to decrease cellular dNTP levels. SAMHD1 contains a target motif for cyclin-dependent kinase 1 (cdk1) (592TPQK595), and cdk1 activity is required for SAMHD1 phosphorylation. Collectively, these findings indicate that phosphorylation modulates the ability of SAMHD1 to block retroviral infection without affecting its ability to decrease cellular dNTP levels
Conserved host response to highly pathogenic avian influenza virus infection in human cell culture, mouse and macaque model systems
<p>Abstract</p> <p>Background</p> <p>Understanding host response to influenza virus infection will facilitate development of better diagnoses and therapeutic interventions. Several different experimental models have been used as a proxy for human infection, including cell cultures derived from human cells, mice, and non-human primates. Each of these systems has been studied extensively in isolation, but little effort has been directed toward systematically characterizing the conservation of host response on a global level beyond known immune signaling cascades.</p> <p>Results</p> <p>In the present study, we employed a multivariate modeling approach to characterize and compare the transcriptional regulatory networks between these three model systems after infection with a highly pathogenic avian influenza virus of the H5N1 subtype. Using this approach we identified functions and pathways that display similar behavior and/or regulation including the well-studied impact on the interferon response and the inflammasome. Our results also suggest a primary response role for airway epithelial cells in initiating hypercytokinemia, which is thought to contribute to the pathogenesis of H5N1 viruses. We further demonstrate that we can use a transcriptional regulatory model from the human cell culture data to make highly accurate predictions about the behavior of important components of the innate immune system in tissues from whole organisms.</p> <p>Conclusions</p> <p>This is the first demonstration of a global regulatory network modeling conserved host response between <it>in vitro </it>and <it>in vivo </it>models.</p
