Seeking and defining the ‘special’ in specialist mental health nursing: A theoretical construct
Authors: Santangelo Peter , Procter Nicholas , Fassett Denise 
Published: February 2017

AbstractIn the context of an enduring debate about the distinct identity of mental health nursing, this qualitative study explored the nature, scope and consequences of mental health nursing practice. Data for interpretation were generated through interviews with 36 mental health nurses, five of their clients and one health care colleague, each of whom were asked to speak in as much detail as possible about what they believe is special about mental health nursing and what had influenced them to arrive at this understanding. Using a constructivist grounded theory approach, the study generated a substantive theory of recovery‐focused mental health nursing expressed as ‘Being in the here and now, side by side, co‐constructing care’. The study revealed that the distinct nature and identity of mental health nursing provides the foundation that primes and drives practice scope and consequences. Conceptual interpretations of the data emphasized the mental health nursing perspective of care as an acquired lens founded in nursing as a profession and enhanced by the relational interplay between the nurse and the client that facilitates the nurse to adopt recovery‐focused practices. This theoretical construct holds the potential to be the mediating connection between client and mental health nurse. By situating mental health nursing and its central role in practice as something co‐constructed, findings from this study can be expanded beyond the Australian context, particularly in terms of mental health nursing's distinct professional identity and practice.

AimSufficient sleep is an important factor in physical and mental health. Sleep duration can be affected by socio‐economic status (SES). This study aimed to examine the association between sleep duration and SES in Korean adolescents.MethodsThis study was conducted with 1608 adolescents aged 12–18 years, based on data from the 2010 to 2012 Korean National Health and Nutrition Examination Survey (KNHANES). Sleep duration was self‐reported in hours and three SES indicators were used: household income, basic livelihood security programmes and type of health insurance. Confounding factors in this study were age, mental health and physical activity.ResultsParticipants’ average age was 15.6 ± 0.05 years and average sleep duration was 7.04 ± 0.05 h. There was a strong association between sleep duration and household income (P < 0.05) rather than other socio‐economic indicators. In addition, it showed that sleep duration was significantly associated with age, body mass index (P < 0.05) and low mood is associated with short sleep and long sleep (>9 h/night). We found similar results in both genders, that is, that the highest income group had shorter sleep duration than the lowest income group.ConclusionsThis study shows that the SES, particularly household income, is an important factor in short sleep duration in Korean adolescents. Our findings suggest that, in future investigations of the adolescent's sleep problem, attention should be paid to household income.

Published: February 2017

AbstractIntegrated multitrophic aquaculture (IMTA) systems are designed mainly for efficient use of resources. Substrates added to aquaculture ponds provide space for periphyton to settle and recover nutrients, making these nutrients available to the species being reared. The present study is centered on the phosphorus budget, analyzing the main ecological compartments of IMTA systems in earthen ponds stocked with Amazon River prawn, Macrobrachium amazonicum, and Nile tilapia, Oreochromis niloticus, with or without different added substrates. The experimental design was completely randomized, with three treatments (without a substrate, with a geotextile fabric substrate, and with a bamboo substrate) and four replications. Phosphorus entered the systems mainly in tilapia feed (ca. 50–61%), inlet water (ca. 17–27%), and fertilizer (ca. 6–7%). Input of phosphorus from other compartments ranged from 1.5 to 1.9%. Most phosphorus was accumulated at the pond bottom as sediment (ca. 60–68%) and fish biomass (ca. 18–26%), or discharged in the outlet water (ca. 7–10%). Feeding is the main driver for the distribution of phosphorus in the ponds. Levels of phosphorus retained in reared animals (20–28%) were higher in these IMTA systems than in tilapia and prawn monocultures (reported as 10–20% and 10–13%, respectively). Nonetheless, the present data showed that the addition of different types of substrates might not improve the recovery of phosphorus in animal biomass as initially supposed. Even so, these IMTA systems decreased the amount of phosphorus released in effluents, and this decrease was enhanced by the addition of substrates, reducing the impact on the receiving waterbodies.

Summary

The hypersensitive response (HR) is a localized programmed cell death phenomenon that occurs in response to pathogen recognition at the site of attempted invasion. Despite more than a century of research on HR, little is known about how it is so tightly regulated and how it can be contained spatially to a few cells.

AtMC1 is an Arabidopsis thaliana plant metacaspase that positively regulates the HR. Here, we used an unbiased approach to identify new AtMC1 regulators. Immunoaffinity purification of AtMC1‐containing complexes led us to the identification of the protease inhibitor AtSerpin1.

Our data clearly showed that coimmunoprecipitation between AtMC1 and AtSerpin1 and formation of a complex between them was lost upon mutation of the AtMC1 catalytic site, and that the AtMC1 prodomain was not required for the interaction. AtSerpin1 blocked AtMC1 self‐processing and inhibited AtMC1‐mediated cell death. Our results constitute an in vivo example of a Serpin acting as a suicide inhibitor in plants, reminiscent of the activity of animal or viral serpins on immune/cell death regulators, including caspase‐1.

These results indicate a conserved function of a protease inhibitor on cell death regulators from different kingdoms with unrelated modes of action (i.e. caspases vs metacaspases).
Estimating the impact of oyster restoration scenarios on transient fish production

Published: February 2017

AbstractOyster reef restoration projects are increasing in number both to enhance oyster density and to retain valuable ecosystem services provided by oyster reefs. Although some oyster restoration projects have demonstrated success by increasing density and biomass of transient fish, it still remains a challenge to quantify the effects of oyster restoration on transient fish communities. We developed a bioenergetics model to assess the impact of selected oyster reef restoration scenarios on associated transient fish species. We used the model to analyze the impact of changes in (1) oyster population carrying capacity; (2) oyster population growth rate; and (3) diet preference of transient fish on oyster reef development and associated transient fish species. Our model results indicate that resident fish biomass is directly affected by oyster restoration and oyster biomass, and oyster restoration can have cascading impacts on transient fish biomass. Furthermore, the results highlight the importance of a favorable oyster population growth rate during early restoration years, as it can lead to rapid increases in mean oyster biomass and biomass of transient fish species. The model also revealed that a transient fish's diet solely dependent on oyster reef‐derived prey could limit the biomass of transient fish species, emphasizing the importance of habitat connectivity in estuarine areas to enhance transient fish species biomass. Simple bioenergetics models can be developed to understand the dynamics of a system and make qualitative predictions of management and restoration scenarios.

BackgroundThere is more to illuminate about people's experiences of surviving out‐of‐hospital cardiac arrest (OHCA) and how such an event affects people's lives over time.AimsThis study aimed to elucidate meanings of people's lived experiences and changes in everyday life during their first year after surviving OHCA.MethodsA qualitative, longitudinal design was used. Eleven people surviving OHCA from northern Sweden agreed to participate and were interviewed 6 and 12 months after the event. A phenomenological hermeneutic interpretation was used to analyse the transcribed texts.FindingsThe structural analysis resulted in two themes: (i) striving to regain one's usual self and (ii) a second chance at life, and subthemes (ia) testing the body, (ib) pursuing the ordinary life, (ic) gratitude for help to survival, (iia) regaining a sense of security with one's body, (iib) getting to know a new self, and (iic) seeking meaning and establishing a future.ConclusionTo conclude, we suggest that people experienced meanings of surviving OHCA over time as striving to regain their usual self and getting a second chance at life. The event affected them in many ways and resulted in a lot of emotions and many things to think about. Participants experienced back‐and‐forth emotions, when comparing their present lives to both their lives before cardiac arrest and those lives they planned for the future. During their first year, participants’ daily lives were still influenced by ‘being dead’ and returning to life. As time passed, they wanted to resume their ordinary lives and hoped for continued lives filled with meaning and joyous activities.

Published: February 2017

BackgroundCompassion is an important ethical foundation of all healthcare professionals especially for nursing. However, there is little understanding of factors which could help and motivate nurses to deliver compassionate care in modern healthcare practices today. Moreover, a cultural context may affect the way compassionate care is delivered by healthcare professionals.Aims and objectivesThis study aimed to explore what facilitates compassionate care in daily practice from the unique perspective of Iranian nurses.Research methodsThis qualitative exploratory study was conducted in four hospitals. In this study, 16 nurses were selected from various wards. Data were collected by in‐depth, face‐to‐face interviews. For data analysis, a conventional content analysis approach was used.ResultsAs the most important theme, the theme ‘deepening individual's capacity for compassionate care’ emerged, which consisted of three categories: the personal system of values and beliefs, patient experience and positive role models of compassion.ConclusionsAddressing and developing nurses’ capacity for compassion is possible by providing organisational support and professional education, next to recruiting nurses with a high motivation to relieve patient suffering. These recommendations would help to provide high‐quality compassionate care in healthcare practices. Moreover, nurses could improve their individual capacity for compassion by following their value and belief system and by considering their colleagues as a role model of compassionate practice.

The pervasiveness and growing complexity of software systems are challenging software engineering to design systems that can adapt their behavior to withstand unpredictable, uncertain, and continuously changing execution environments. Control theoretical adaptation mechanisms have received growing interest from the software engineering community in the last few years for their mathematical grounding, allowing formal guarantees on the behavior of the controlled systems. However, most of these mechanisms are tailored to specific applications and can hardly be generalized into broadly applicable software design and development processes.
This article discusses a reference control design process, from goal identification to the verification and validation of the controlled system. A taxonomy of the main control strategies is introduced, analyzing their applicability to software adaptation for both functional and nonfunctional goals. A brief extract on how to deal with uncertainty complements the discussion. Finally, the article highlights a set of open challenges, both for the software engineering and the control theory research communities.
Oscillatory lower body negative pressure impairs working memory task-related functional hyperemia in healthy volunteers

Published: February 2017

Neurovascular coupling (NVC) describes the link between an increase in task-related neural activity and increased cerebral blood flow denoted “functional hyperemia.” We previously showed induced cerebral blood flow oscillations suppressed functional hyperemia; conversely functional hyperemia also suppressed cerebral blood flow oscillations. We used lower body negative pressure (OLBNP) oscillations to force oscillations in middle cerebral artery cerebral blood flow velocity (CBFv). Here, we used N-back testing, an intellectual memory challenge as a neural activation task, to test the hypothesis that OLBNP-induced oscillatory cerebral blood flow can reduce functional hyperemia and NVC produced by a working memory task and can interfere with working memory. We used OLBNP (−30 mmHg) at 0.03, 0.05, and 0.10 Hz and measured spectral power of CBFv at all frequencies. Neither OLBNP nor N-back, alone or combined, affected hemodynamic parameters. 2-Back power and OLBNP individually were compared with 2-back power during OLBNP. 2-Back alone produced a narrow band increase in oscillatory arterial pressure (OAP) and oscillatory cerebral blood flow power centered at 0.0083 Hz. Functional hyperemia in response to 2-back was reduced to near baseline and 2-back memory performance was decreased by 0.03-, 0.05-, and 0.10-Hz OLBNP. OLBNP alone produced increased oscillatory power at frequencies of oscillation not suppressed by added 2-back. However, 2-back preceding OLBNP suppressed OLBNP power. OLBNP-driven oscillatory CBFv blunts NVC and memory performance, while memory task reciprocally interfered with forced CBFv oscillations. This shows that induced cerebral blood flow oscillations suppress functional hyperemia and functional hyperemia suppresses cerebral blood flow oscillations. NEW & NOTEWORTHY We show that induced cerebral blood flow oscillations suppress functional hyperemia produced by a working memory task as well as memory task performance. We conclude that oscillatory cerebral blood flow produces causal reductions of memory task neurovascular coupling and memory task performance. Reductions of functional hyperemia are constrained by autoregulation.
Right ventricular metabolism during venoarterial extracorporeal membrane oxygenation in immature swine heart in vivo
Authors: Kajimoto Masaki , Ledee Dolena R. , Isern Nancy G. , Portman Michael A. 
Published: February 2017

Venoarterial extracorporeal membrane oxygenation (VA-ECMO) provides hemodynamic rescue for patients encountering right or left ventricular (RV or LV) decompensation, particularly after surgery for congenital heart defects. ECMO, supported metabolically by parenteral nutrition, provides reductions in myocardial work and energy demand and, therefore, enhances functional recovery. The RV must often assume systemic ventricular pressures and function on weaning from VA-ECMO. However the substrate utilization responses of the RV to VA-ECMO or stimulation are unknown. We determined RV and LV substrate utilization response to VA-ECMO in immature swine heart. Mixed-breed male Yorkshire pigs (33–49 days old) underwent normal pressure volume loading (control, n = 5) or were unloaded by VA-ECMO (ECMO, n = 10) for 8 h. Five pigs with ECMO received intravenous thyroid hormone [triiodothyronine (T3)] to alter substrate utilization. Carbon 13 (13C)-labeled substrates (lactate and medium-chain and long-chain fatty acids) were systemically infused as metabolic tracers. Analyses by nuclear magnetic resonance showed that both ventricles have similar trends of fractional 13C-labeled substrate contributions to the citric acid cycle under control conditions. VA-ECMO produced higher long-chain fatty acids and lower lactate contribution to the citric acid cycle via inhibition of pyruvate dehydrogenase, whereas T3 promoted lactate metabolism in both ventricles. However, these metabolic shifts were smaller in RV, and RV fatty acid contributions showed minimal response to perturbations. Furthermore, VA-ECMO and T3 also achieved high [phosphocreatine]/[ATP] and low [NADH]/[NAD+] in LV but not in RV. These data suggest that the RV shows decreased ability to modify substrate utilization and achieve improvements in energy supply/demand during VA-ECMO. NEW & NOTEWORTHY We showed that the right ventricle unloaded by venoarterial extracorporeal membrane oxygenation (VA-ECMO) has diminished capacity to alter substrate utilization compared with the left ventricle. This decrease in metabolic flexibility contributes to the inability to increase high-energy phosphate reserves during myocardial rest by VA-ECMO.

Published: February 2017

Studies suggest that patients with subclinical hypothyroidism (SH) have sympathovagal imbalance, which could lead to a slower heart rate (HR) response in the transition from rest to exercise. Thus the objective of this study was to investigate the behavior of the HR kinetics in patients with SH during the transition from rest to exercise. The study included 18 SH women [thyroid stimulating hormone (TSH) = 6.95 ± 2.94 μIU/ml and free thyroxine (FT4) = 0.96 ± 0.15 ng/dl] and 17 euthyroid women (TSH = 2.28 ± 0.84 μIU/ml and FT4 = 0.98 ± 0.07 ng/dl). Both groups were matched for physical activity, menopausal status, and age. The HR kinetics was obtained during the course of a constant-load exercise (50 W), for 6 min, in a cycle ergometer, and quantified from the mean response time (MRT), which is equivalent to the time taken to reach 63% of the HR at steady state. SH patients showed slower HR kinetics than the control group (MRT = 48.5 ± 17.6 vs. 36.0 ± 10.3 s, P = 0.015). The MRT has been shown to correlate with the level of physical activity ( r = −0.361; P = 0.033) and with the subjective perception of exertion at the end of the exercise ( r = 0.365; P = 0.031). It is concluded that SH patients have slower HR kinetics in the transition from rest to exercise compared with euthyroid women, with this impairment being associated with lower levels of physical activity. NEW & NOTEWORTHY Subclinical hypothyroidism patients have slower heart rate kinetics in the transition from rest to exercise when performing a constant-load exercise at 50 W.
