Nursing Students’ Attitudes and Use of Holistic Therapies for Stress Relief

Purpose: The purpose of this study was to explore student nurses’ openness to using or recommending holistic therapies, the strategies they use to manage stress from school or work, and their perceptions of the impact of holistic therapies on personal health. Study Design: Qualitative component of a quasi-experimental, mixed-methods study. Methods: A convenience sample of undergraduate nursing students in a southeastern U.S. university completed baseline surveys, including demographics and three open-ended questions regarding attitudes toward holistic therapies and strategies used for stress management. Qualitative thematic analysis was undertaken to identify recurring themes in textual data. Findings: Students are open to using or recommending holistic therapies but identify lack of knowledge and lack of time as barriers to their practice. Among strategies used by student nurses to manage stress from school or work were physical activity, prayer and meditation, time management, distraction, socialization, artistic pursuits, animal interactions, and other activities. Themes describing holistic therapies’ impact on personal health were wholeness, self-empowerment, relaxation/restoration, and alternative/complement to traditional medicine. Conclusions: Findings indicate receptiveness by student nurses to the use of holistic therapies but point to the need for the inclusion of informational as well as experiential education on holistic therapies within nursing curricula.
Physical activity, mediating factors and risk of colon cancer: insights into adiposity and circulating biomarkers from the EPIC cohort.

Background There is convincing evidence that high physical activity lowers the risk of colon cancer; however, the underlying biological mechanisms remain largely unknown. We aimed to determine the extent to which body fatness and biomarkers of various biologically plausible pathways account for the association between physical activity and colon cancer. Methods We conducted a nested case-control study in a cohort of 519 978 men and women aged 25 to 70 years followed from 1992 to 2003. A total of 713 incident colon cancer cases were matched, using risk-set sampling, to 713 controls on age, sex, study centre, fasting status and hormonal therapy use. The amount of total physical activity during the past year was expressed in metabolic equivalent of task [MET]-h/week. Anthropometric measurements and blood samples were collected at study baseline. Results High physical activity was associated with a lower risk of colon cancer: relative risk ≥91 MET-h/week vs <91 MET-h/week = 0.75 [95% confidence interval (CI): 0.57 to 0.96]. In mediation analyses, this association was accounted for by waist circumference: proportion explained effect (PEE) = 17%; CI: 4% to 52%; and the biomarkers soluble leptin receptor (sOB-R): PEE = 15%; 95% CI: 1% to 50% and 5-hydroxyvitamin D (25[OH]D): PEE = 30%; 95% CI: 12% to 88%. In combination, these factors explained 45% (95% CI: 20% to 125%) of the association. Beyond waist circumference, sOB-R and 25[OH]D additionally explained 10% (95% CI: 1%; 56%) and 23% (95% CI: 6%; 111%) of the association, respectively. Conclusions Promoting physical activity, particularly outdoors, and maintaining metabolic health and adequate vitamin D levels could represent a promising strategy for colon cancer prevention.
Development of an Index of Engagement in HIV Care: An Adapted Internet-Based Delphi Process

Background Improving engagement in medical care among persons living with human immunodeficiency virus (HIV) is critical to optimizing clinical outcomes and reducing onward transmission of HIV. However, a clear conceptualization of what it means to be engaged in HIV care is lacking, and thus efforts to measure and enhance engagement in care are limited. Objective This paper describes the use of a modified online Delphi process of consensus building to solicit input from a range of HIV and non-HIV researchers and providers, and to integrate that input with focus group data conducted with HIV-infected patients. The overarching goal was to generate items for a patient-centered measure of engagement in HIV care for use in future research and clinical practice. Methods We recruited 66 expert panelists from around the United States. Starting with six open-ended questions, we used four rounds of online Delphi data collection in tandem with 12 in-person focus groups with patients and cognitive interviews with 25 patients. Results We recruited 66 expert panelists from around the United States and 64 (97%) were retained for four rounds of data collection. Starting with six open-ended questions, we used four rounds of online Delphi data collection in tandem with 12 in-person focus groups with patients and cognitive interviews with 25 patients. The process resulted in an expansion to 120 topics that were subsequently reduced to 13 candidate items for the planned assessment measure. Conclusions The process was an efficient method of soliciting input from geographically separated and busy experts across a range of disciplines and professional roles with the aim of arriving at a coherent definition of engagement in HIV care and a manageable set of survey items to assess it. Next steps are to validate the utility of the new measure in predicting retention in care, adherence to treatment, and clinical outcomes among patients living with HIV.
Protein phosphorylation maintains the normal function of cloned human Cav2.3 channels

R-type currents mediated by native and recombinant Cav2.3 voltage-gated Ca2+ channels (VGCCs) exhibit facilitation (run-up) and subsequent decline (run-down) in whole-cell patch-clamp recordings. A better understanding of the two processes could provide insight into constitutive modulation of the channels in intact cells, but low expression levels and the need for pharmacological isolation have prevented investigations in native systems. Here, to circumvent these limitations, we use conventional and perforated-patch-clamp recordings in a recombinant expression system, which allows us to study the effects of cell dialysis in a reproducible manner. We show that the decline of currents carried by human Cav2.3+&bgr;3 channel subunits during run-down is related to adenosine triphosphate (ATP) depletion, which reduces the number of functional channels and leads to a progressive shift of voltage-dependent gating to more negative potentials. Both effects can be counteracted by hydrolysable ATP, whose protective action is almost completely prevented by inhibition of serine/threonine but not tyrosine or lipid kinases. Protein kinase inhibition also mimics the effects of run-down in intact cells, reduces the peak current density, and hyperpolarizes the voltage dependence of gating. Together, our findings indicate that ATP promotes phosphorylation of either the channel or an associated protein, whereas dephosphorylation during cell dialysis results in run-down. These data also distinguish the effects of ATP on Cav2.3 channels from those on other VGCCs because neither direct nucleotide binding nor PIP2 synthesis is required for protection from run-down. We conclude that protein phosphorylation is required for Cav2.3 channel function and could directly influence the normal features of current carried by these channels. Curiously, some of our findings also point to a role for leupeptin-sensitive proteases in run-up and possibly ATP protection from run-down. As such, the present study provides a reliable baseline for further studies on Cav2.3 channel regulation by protein kinases, phosphatases, and possibly proteases.
Psychological Distress Among Smokers in the United States: 2008–2014

Abstract Introduction Decline in smoking in the United States has slowed over the past 25 years. Mental health problems are common among smokers, and may be an impediment to quitting and remaining abstinent. The study investigated the relationship between serious (past-30-day) psychological distress (SPD) and smoking, estimated trends in the prevalence of SPD among current, former, and never smokers in the United States from 2008 to 2014, and investigated whether heterogeneity in these trends varied by sociodemographic characteristics. Methods Data were drawn from the National Household Survey on Drug Use (NSDUH), an annual cross-sectional study of persons ages 12 and over (N = 270 227). SPD and smoking in the past 30 days were examined using logistic regression models among adults 18 and older. The prevalence of SPD was examined annually among current, former, and never smokers from 2008 to 2014. Results SPD increased among smokers in the United States from 2008 to 2014. An increase in SPD was more rapid among non-daily smokers than daily smokers. The prevalence of SPD was higher among younger smokers, those with less formal education and lower annual family income and higher among current smokers than former and never smokers. The relationships between SPD and smoking were stronger among smokers with higher education levels and annual family income. Conclusions Our findings suggest an increase in SPD among smokers over time and that as smoking has declined, those with SPD are comprising a greater proportion of the remaining smokers. Results suggest that mental health must be integrated into mainstream tobacco control efforts. Implications The greater prevalence and increasing rate of Serious Psychological Distress among smokers, relative to former- and never-smokers, from 2008 to 2014 provides support that the greater mental health burden among smokers may be contributing to the slowed reduction in smoking prevalence in the United States. In addition, relationships between SPD and smoking were consistently stronger among smokers with higher levels of education and annual family income. Such results suggest the necessity of incorporating mental health treatments in tobacco use reduction efforts.
Associations Between Fixed-Term Employment and Health and Behaviors: What are the Mechanisms?

Objective: To analyze the associations between fixed-term employment and health (work ability and mental health) and behaviors (engagement and performance). Psychological contract fulfilment (PCF) and breach (PCB) are investigated as potential mediators of these associations. Methods: Seven hundred workers employed on fixed-term contracts from a broad range of organizations participated in the study. The Structural Equation Model was performed to analyze the data. Results: Mediation analyses revealed that good physical and mental health and productivity are more likely to be achieved by those workers who perform non-manual work and (to some extent) accept their contracts because they experience high levels of PCF and low levels of PCB. Conclusions: Apart from the lack of physical workload, psychological contract fulfilment has been revealed as yet another significant mediator between a higher socioeconomic position and good health and productivity of fixed-term workers.
M1 muscarinic receptor facilitates cognitive function by interplay with AMPA receptor GluAl subunit

M1 muscarinic acetylcholine receptors (M1 mAChRs) are the most abundant muscarinic receptors in the hippocampus and have been shown to have procognitive effects. AMPA receptors (AMPARs), an important subtype of ionotropic glutamate receptors, are key components in neurocognitive networks. However, the role of AMPARs in procognitive effects of M1 mAChRs and how M1 mAChRs affect the function of AMPARs remain poorly understood. Here, we found that basal expression of GluA1, a subunit of AMPARs, and its phosphorylation at Ser845 were maintained by M1 mAChR activity. Activation of M1 mAChRs promoted membrane insertion of GluA1, especially to postsynaptic densities. Impairment of hippocampus‐dependent learning and memory by antagonism of M1 mAChRs paralleled the reduction of GluA1 expression, and improvement of learning and memory by activation of M1 mAChRs was accompanied by the synaptic insertion of GluA1 and its increased phosphorylation at Ser845. Furthermore, abrogation of phosphorylation of Ser845 residue of GluA1 ablated M1 mAChR‐mediated improvement of learning and memory. Taken together, these results show a functional correlation of M1 mAChRs and GluA1 and the essential role of GluA1 in M1 mAChR‐mediated cognitive improvement. —Zhao, L. ‐X. , Ge, Y. ‐H. , Xiong, C. ‐H. , Tang, L. , Yan, Y. ‐H. , Law, P.‐Y. , Qiu, Y. , Chen, H. ‐Z.

Characterization of TiO2/TiO2—SiO2 Coated Cellulose Textiles

This paper describes work directed at forming nanoparticle-populated titanium surfaces on man-made cellulose fibers that facilitate photocatalysis. One of the techniques placed a spacer of silica (SiO2) between the tethered titanium nanoparticles and the underlying cellulose. While the latter treatment provided the best protection of the cellulose from the damage facilitated by the titanium particle when exposed to sunlight, the former provided better photocatalysis. Transmission electron microscopy (TEM) revealed particle morphology of TiO2 nanoparticles captured by the silica network. In that way silica is used as a binder between TiO2 nanoparticles and cellulose fibers. The differences in surface morphologies between TiO 2 and TiO2—SiO2 coatings were detected using scanning electron microscopy (SEM). Moreover, the results of streaming potential measurements (US ) clearly indicate changes of the fibers’ surface properties, which confirmed the presence of TiO2 and SiO2 particles, respectively.
Paternal adaptation in first-time fathers: a phenomenological study

Abstract Objective: This study aimed to explore men’s experiences of paternal adaptation during their first year of transition to parenthood. Background: Stepping into fatherhood is one of the most important events that may occur in a man’s life and can lead to fundamental changes in their identity and lifestyle. However, to our knowledge, no studies have been conducted on men’s experiences of paternal adaptation in an Iranian context. Methods: In this phenomenological study, 15 Iranian men who had the experience of parenting for the first time were recruited using the purposeful sampling method. In-depth semi-structured interviews guided by a questionnaire were used to collect data. The data were analysed using interpretative phenomenological analysis. Results: The data analysis resulted in the development of 26 themes, 8 subordinate themes and 3 superordinate themes. The superordinate themes included ‘steps toward adaptation’, ‘obstacles to the path of adaptation’ and ‘stabilisation in the paternal position’. Conclusion: Perceived self-efficacy and satisfaction in fatherhood means an adaptation to the paternal role. Factors influencing paternal adaptation can be classified into the domains of ‘facilitating factors’ and ‘inhibiting factors’.
Exploring the association of urban or rural county status and environmental, nutrition- and lifestyle-related resources with the efficacy of SNAP-Ed (Supplemental Nutrition Assistance Program-Education) to improve food security

Abstract Objective To investigate the association of policy, systems and environmental factors with improvement in household food security among low-income Indiana households with children after a Supplemental Nutrition Assistance Program-Education (SNAP-Ed) direct nutrition education intervention. Design Household food security scores measured by the eighteen-item US Household Food Security Survey Module in a longitudinal randomized and controlled SNAP-Ed intervention study conducted from August 2013 to April 2015 were the response variable. Metrics to quantify environmental factors including classification of urban or rural county status; the number of SNAP-authorized stores, food pantries and recreational facilities; average fair market housing rental price; and natural amenity rank were collected from government websites and data sets covering the years 2012–2016 and used as covariates in mixed multiple linear regression modelling. Setting Thirty-seven Indiana counties, USA, 2012–2016. Subjects SNAP-Ed eligible adults from households with children (n 328). Results None of the environmental factors investigated were significantly associated with changes in household food security in this exploratory study. Conclusions SNAP-Ed improves food security regardless of urban or rural location or the environmental factors investigated. Expansion of SNAP-Ed in rural areas may support food access among the low-income population and reduce the prevalence of food insecurity in rural compared with urban areas. Further investigation into policy, systems and environmental factors of the Social Ecological Model are warranted to better understand their relationship with direct SNAP-Ed and their impact on diet-related behaviours and food security.
Optimizing stability in AO/OTA 31-A2 intertrochanteric fracture fixation in older patients with osteoporosis

Objectives To compare the functional and radiographic outcomes of InterTAN nail (IT) and proximal femoral nail anti-rotation (PFNA) for managing primary AO/OTA 31-A2 intertrochanteric hip fractures (IHFs) in older osteoporotic patients. Methods Patients aged 60 years or older who received surgical treatment for IHFs (AO/OTA 3.1A2.1-A2.3) with IT or PFNA were retrospectively evaluated. The primary outcome was the postoperative treatment failure rate. The secondary outcome was the Harris Hip Score (HHS). Results A total of 326 osteoporotic cases (326 hips: IT, n = 162; PFNA, n = 164) were assessed with a mean follow-up of 43.5 months (range, 38–48 months). For the entire cohort, the incidence of postoperative treatment failure (periprosthetic fracture and reoperation) was 29/326 (8.9%); the IT-treated cohort (7/162, 4.3%) had a significantly lower rate compared with the PFNA-treated cohort (22/165, 13.3%). The incidence of postoperative periprosthetic fractures was significantly lower in the IT-treated cohort than in the PFNA-treated cohort (2.5% vs 7.9%). The postoperative HHS at the final follow-up was not significantly different between the groups. Conclusion IT might show a better outcome in managing osteoporotic AO/OTA 31-A2 IHFs in terms of periprosthetic fracture and reoperation compared with PFNA.
Intraoperative on-the-fly organ-mosaicking for laparoscopic surgery

The goal of computer-assisted surgery is to provide the surgeon with guidance during an intervention using augmented reality (AR). To display preoperative data correctly, soft tissue deformations that occur during surgery have to be taken into consideration. Optical laparoscopic sensors, such as stereo endoscopes, can produce a 3D reconstruction of single stereo frames for registration. Due to the small field of view and the homogeneous structure of tissue, reconstructing just a single frame in general will not provide enough detail to register and update preoperative data due to ambiguities. In this paper, we propose and evaluate a system that combines multiple smaller reconstructions from different viewpoints to segment and reconstruct a large model of an organ. By using GPU-based methods we achieve near real-time performance. We evaluated the system on an ex-vivo porcine liver (4.21mm± 0.63) and on two synthetic silicone livers (3.64mm ± 0.31 and 1.89mm ± 0.19) using three different methods for estimating the camera pose (no tracking, optical tracking and a combination).
Classification accuracy of individual and combined executive functioning embedded performance validity measures in mild traumatic brain injury

ABSTRACT The development of more sophisticated performance validity measures is important due to concerns with coaching as well as providing clinicians with a greater variety of options when assessing performance validity. Examinees with noncredible performance may find it more difficult to elude detection by PVTs derived from arithmetical summation or logistic regression. The present study evaluated the classification accuracy of several executive functioning (EF) variables as PVTs both individually and when combined into derived variables. The current study evaluated a simple mathematic summation of embedded PVT scores and a logistic regression-based formula based on embedded PVTs from executive function measures. A total of 155 consecutive patients completed neuropsychological evaluation after sustaining a mild traumatic brain injury (MTBI) were studied and were placed into a PVT-PASS (N = 95, mean age = 44.9, SD = 12.55, mean education = 13.45, SD = 2.23, 38% male, 97% Caucasian) or PVT-FAIL group (N = 60, mean age = 44.1, SD = 15.47, mean education = 13.05, SD = 2.58, 55% male, 92% Caucasian). Trail Making Test B, Wisconsin Card Sorting Test, and Stroop Color Word Test were summed and also used in logistic regression to predict whether patients had credible performance. Both the mathematical summation and the logistic regression methods achieved excellent classification accuracy (summation AUC = .79; logistic regression AUC = .82) with higher sensitivity than individual PVTs.
