Uncertainty in illness among people with mental ill health: a nursing perspective
Authors: Wolfensberger Peter , Hahn Sabine , van Teijlingen Edwin , Thomas Sarah 
Published: November 2019

Background/Aims: Uncertainty in illness is a well-known concept in health care literature. A considerable volume of research has investigated how people adapt to different health conditions and how the concept of uncertainty in illness relates to those populations. The aim of this article is to explore the concept of uncertainty in illness among mental health nurses and to provide an understanding of its relevance to people living with mental ill health. Method: A focus group was conducted with mental health nurses at an international psychiatric nursing conference. The focus group discussion was recorded and then transcribed and thematically analysed. Results: Uncertainty in illness among people living with mental ill health exists and manifests itself in various ways: uncertainty in the context of loss, uncertainty as a stimulus for change, and uncertainty as an integral part of the human experience and existence. Conclusions: Even though contemporary approaches in mental health nursing do not directly address uncertainty, the concept and its implications need to be considered and raised further among mental health professionals in order to improve support for people living with mental ill health in their process of personal recovery.
The burden of periodontal disease
Authors: Butt Kasim , Butt Razia , Sharma Praveen 
Published: November 2019

Periodontal disease is the most common chronic inflammatory disease seen in humans. It is a major public health concern, and in its severe form affects approximately 10.8% or 743 million people aged 15−99 worldwide. Trends such as the rise of smoking in developing countries, the obesity and diabetes epidemic, coupled with an ageing population with greater tooth retention, are all likely to increase the burden of periodontitis still further in the UK and worldwide. Consequences of periodontitis include hypermobility of teeth, tooth migration, drifting and eventual tooth loss. Tooth loss can directly affect the quality of life of a person in terms of reduced functional capacity, self-esteem and social relationships. CPD/Clinical Relevance: This article reports the prevalence of periodontal disease in the UK and worldwide, along with the consequences of periodontitis. The importance of timely diagnosis to avoid litigation is discussed, as is the importance of effective management of periodontitis in order to improve patients' oral health-related quality of life.

Authors: Lopez-Lago Aaron , Choudhury Mahbuba Tasnima , Sharma Praveen 
Published: November 2019

That the mouth and the body are not disconnected should come as no surprise. In this article, the links between periodontal and systemic health will be reviewed by investigating these in both directions, starting with the more familiar effects of systemic conditions on periodontal health and progressing to the emerging effects of periodontal health on systemic health. Where suitable, tips will be provided for practitioners caring for patients with periodontitis and systemic diseases. CPD/Clinical Relevance: In recognition of the important role that the oral cavity plays in the body and the important role that oral healthcare providers play in the management of the general wellbeing of patients, this article highlights the link between periodontitis and systemic heath. This allows practitioners to care more holistically for their patients.
An update on non-surgical management of periodontal diseases

Non-surgical periodontal therapy (NSPT) underpins all other restorative treatment which takes place in the mouth. Therefore a thorough understanding of the process of delivery of effective NSPT and long-term maintenance of periodontal health is essential for every dental practitioner. This article covers the steps involved and discusses the benefits and challenges which may be encountered. CPD/Clinical Relevance: This article highlights the benefits and challenges of non-surgical management of periodontal disease and the key role that the patient plays in achieving and maintaining periodontal health.
The role of maintenance in periodontal disease
Authors: Batt Joanna , Ower Phil , Sharma Praveen 
Published: November 2019

There is increasing recognition, made explicit in the new classification for periodontitis, that periodontitis is a lifelong disease that is not ‘cured’ but rather ‘managed’. This paper focuses on how the response to periodontal treatment is ideally measured and how decisions are made as to whether the treatment has been ‘successful’ or not. The roles of both the patient and practitioner in the maintenance of periodontal health for those patients who respond to initial therapy are crucial. Patients not responding to initial, non-surgical periodontal therapy also need to be appropriately managed, as outlined in this paper. CPD/Clinical Relevance: This paper highlights the importance of maintenance of periodontal health, as an integral part of the overall management of patients with periodontitis, in order to minimize further periodontal breakdown and eventual tooth loss.
Peri-implant disease part 1: diagnosis and assessment parameters
Authors: Daly Alex , McCracken Giles 
Published: November 2019

Where suitable, dental implants are praised as a method of providing fixed solutions with good longevity, and providing greatly improved retention for removable prostheses, resulting in increased levels of patient satisfaction and quality of life. However, with increasing evidence of long-term follow-up, there is a growing recognition of the susceptibility of dental implants to peri-implant diseases; peri-mucositis and peri-implantitis. This paper discusses the features of peri-implant disease and important aspects of assessment criteria. CPD/Clinical Relevance: This paper highlights the importance of supportive maintenance care for patients with dental implants, as well as the features and assessment of peri-implant disease.
Comparison of sterile polyacrylate wound dressing with activated carbon cloth and a standard non-adhesive hydrocellular foam dressing with silver: a randomised controlled trial protocol
Authors: Probst Sebastian , Saini Camille , Skinner Monika Buehrer 
Published: November 2019

Objective: Hard-to-heal wounds such as leg (LU) or diabetic foot ulcers (DFU) are slow healing, have a high recurrence rate and are associated with infection, smell and exudate. Current therapeutic approaches are multifaceted and focus on improving wound healing and preventing recurrences. Advanced wound dressings, especially super absorbent dressings are an important aspect of wound care, as hard-to-heal wounds tend to produce excessive amounts of exudate, which may contribute to maceration and excoriation, thus delaying wound healing. Additionally, excessive wound exudate is associated with malodour. Therefore, an important aspect of care is the management of exudate and odour. The use of effective advanced wound dressings is a promising strategy to achieve adequate absorption of wound exudate and malodour promoting wound healing. The aim of the current study is to determine whether there is a difference in wound size reduction between wounds dressed with either a sterile polyacrylate wound dressing with activated carbon cloth or a hydrocellular foam dressing with silver. Method: A randomised controlled trial with 248 participants in one wound care outpatient clinic is proposed. Randomisation will be concealed. The outcome assessor will be blinded to the group allocation of participants. Conclusion: This research project compares two wound dressings in an everyday care setting. Since the cost of hard-to-heal wounds to individuals, the economy and society is high, an evaluation of which wound dressing leads to a faster reduction of wound size and subsequent wound healing is an important issue/question for the individuals affected, their families, society and the health-care system.

Authors: Moffatt Christine J. , Murray Susie , Aubeeluck Aimee , Quere Isabelle 
Published: November 2019

Objective: The purpose of this study was to explore the challenges of communication between patients and health professionals, and patient adherence to treatment for hard-to-heal wounds when using negative wound pressure therapy (NPWT). Methods: Face-to-face, semi-structured interviews were conducted with patients undergoing NPWT. Specific features of the NPWT device were the priority for discussion although other factors central to communication and adherence were also explored. Results: A total of 24 patients took part in the study. Data saturation was achieved during the analysis. Patients required ongoing support to understand complex and often protracted treatment and this was particularly important when specialist technology was used. A distinction was highlighted between those who decided not to adhere with therapy and those who did so unintentionally. Participants faced difficulties in their communications with health professionals and in ensuring their needs were listened to and addressed. Conclusion: Further research is needed to achieve a better understanding of this distinction and to evaluate interventions which can sustain adherence behaviours. Further exploration of how to establish concordant patient/health professional communications is warranted.

Objective: A method for measuring mechanical withdrawal threshold of full-thickness cutaneous wound pain in animal models is lacking. This study aimed to confirm the validity and reactivity of the von Frey test in full-thickness cutaneous wounds in rats. Method: A 1.5cm-diameter wound was established on the dorsal areas of male Sprague-Dawley rats and subcutaneously injected with either morphine hydrochloride (5.0mg/kg) or indomethacin (2.5mg/kg) with a 27-gauge needle on day three post-wounding. On day five post-wounding, an injection of morphine hydrochloride, indomethacin or lambda-carrageenan (1.0%) into the granulation tissue was also administered. The withdrawal threshold of mechanical stimulation of the wound edge was compared in each group before treatment with injection and at two, four, eight and 24 hours after injection. Results: A total of 40 rats were used in the study. Since more severe inflammation in and around the wound was induced on day three post-wounding than that of day five, the withdrawal threshold measured on day three post-wounding was significantly lower than that of day five. The decrease of the withdrawal threshold was depressed by morphine hydrochloride and indomethacin treatment on day three post-wounding. While there was no significant difference between the changes in the withdrawal threshold after indomethacin treatment on day five post-wounding, we observed an increased withdrawal threshold after morphine hydrochloride treatment and decreased withdrawal threshold after lambda-carrageenan treatment on day five post-wounding. Conclusion: The results suggest that the von Frey test can be applied to measure the mechanical withdrawal threshold of full-thickness dorsal wounds in rats.

HighlightsThe atomizer droplet size should be considered an important factor when designing aeroponic systems.Airless atomizers had significant positive effects on plant growth, total polyphenol content, and antioxidant activity.Airless atomizers and a spraying interval of 20 min on and 3 h off was the best combination for lettuce plants.Abstract. Throughout our literature review, the effects of various aeroponic atomizers (droplet sizes) on specific leafy plant growth and quality were minimally reported. Lettuce ( L.) is one of the most popular leafy vegetables consumed around the world. The present study sought to determine the effects of various aeroponic atomizers (droplet sizes) on the growth, total polyphenol content, and antioxidant activity of lettuce plants. Aeroponic systems were designed and manufactured using three kinds of atomizers: air-based (A1), airless (A2), and ultrasonic fogger (A3). The South China Agricultural leafy vegetable B nutrient solution was selected as the cultivating solution. Additionally, the spraying time and spraying interval were set at 20 min on and 3 h off. The sizes of the droplets generated by these atomizers were measured using a laser particle size analyzer, and the measured average droplet sizes generated by the A1, A2, and A3 atomizers were 23.281, 46.386, and 3.451 µm, respectively. The results showed that the lettuce plants treated with the A2 atomizers exhibited more significant effects on the growth, total polyphenol content, and antioxidant activity of the lettuce compared to those treated with the A1 and A3 atomizers. The results indicated that nutrient solution droplet size should be considered an essential factor when designing an aeroponic system. Keywords: Aeroponic, Antioxidant activity, Soilless, Spraying time, Total polyphenol content.

HighlightsThe rice dust collection performance of bag filters was investigated.The pressure drop and rice dust collection efficiency were measured with various parameters.Correlation equations are suggested for the pressure drop across a clean filter medium and across the dust cake.Abstract. Because rice dust constitutes a form of air pollution, bag filters are widely used in rice processing facilities. Rice dust has various particle sizes, and the dust concentration in air is low with rice dust. Research on the rice dust collection performance of bag filters is necessary for effective dust collection in rice processing facilities. The objective of this study was to investigate the rice dust collection performance of bag filters. The pressure drop and rice dust collection efficiency were measured with various face velocities, dust concentrations, and fabric filter media. The dust collection efficiency decreased slightly with increases in the face velocity and in the maximum pressure drop in normal conditions. In addition, correlation equations of the pressure drop across a clean filter medium and across the dust cake are suggested to predict the pressure drop in overloaded conditions in rice processing facilities. The average error was 20.2%, and it decreased with increasing pressure drop. Using the correlation equations, bag filters can be managed to remove the deposited dust before the pressure drop significantly increases or reaches its maximum value. Keywords: Bag filter, Dust collection efficiency, Pressure drop, Rice dust.
Multiplicity and concentration results for magnetic relativistic Schrödinger equations
Authors: Xia Aliang 
Published: November 2019

Abstract
In this paper, we consider the following magnetic pseudo-relativistic Schrödinger equation

$$\begin{array}{}
\displaystyle
\sqrt{\left(\frac{\varepsilon}{i}\nabla-A(x)\right)^2+m^2}u+V(x)u= f(|u|)u \quad {\rm in}\,\,\mathbb{R}^N,
\end{array}$$
where ε > 0 is a parameter, m > 0, N ≥ 1, V : ℝN → ℝ is a continuous scalar potential satisfies V(x) ≥ − V0 > − m for any x ∈ ℝN and f : ℝN → ℝ is a continuous function. Under a local condition imposed on the potential V, we discuss the number of nontrivial solutions with the topology of the set where the potential attains its minimum. We proof our results via variational methods, penalization techniques and Ljusternik-Schnirelmann theory.
Regularity Properties for a Class of Non-uniformly Elliptic Isaacs Operators
Authors: Ferrari Fausto , Vitolo Antonio 
Published: November 2019

Abstract
We consider the elliptic differential operator defined as the sum of the minimum and the maximum eigenvalue of the Hessian matrix, which can be viewed as a degenerate elliptic Isaacs operator, in dimension larger than two. Despite of nonlinearity, degeneracy, non-concavity and non-convexity, such an operator generally enjoys the qualitative properties of the Laplace operator, as for instance maximum and comparison principles, ABP and Harnack inequalities, Liouville theorems for subsolutions or supersolutions. Existence and uniqueness for the Dirichlet problem are also proved as well as local and global Hölder estimates for viscosity solutions. All results are discussed for a more general class of weighted partial trace operators.
Cracking wise to break the ice: The potential for racial humor to ease interracial anxiety
Authors: Borgella Alex M. , Howard Simon , Maddox Keith B. 
Published: November 2019

AbstractWe explore the idea that humor focused on social group disparities can be a viable tool to reduce some of the negative outcomes associated with interracial interactions. These interactions are crucial in promoting common understanding about the causes of social, educational, and economic disparities and crafting solutions to redress them. However, investigations have demonstrated that interracial interactions can be emotionally and cognitively taxing, and for these reasons are often avoided. When not avoided, these interactions often result in negative outcomes. Anxiety has been identified as a key factor in these outcomes as majority group members cope with concerns over appearing biased and minority group members cope with concerns over being discriminated against. Humor may be able to alleviate anxiety that contributes to negative outcomes associated with intergroup dialogue. To explore this claim, we first review the literature on interracial interactions and the role of anxiety in shaping them. We then discuss investigations exploring the impact of group-related humor, specifically disparagement humor, on intergroup perceptions. Finally, we draw from both literatures to consider factors that might determine race-related humor’s potential to facilitate positive interracial dialogue through anxiety reduction. We conclude with some possible areas for further research.
Neo-Gricean perspective on irony, deception, and humor vs. some insights from experimental studies
Authors: Piskorska Agnieszka 
Published: November 2019

Abstract
This article discusses a neo-Gricean approach to irony, deception and humor developed by Marta Dynel, confronting some of its assumptions and implications with results of experimental research. It is stated that Dynel’s modifications and elaborations of Grice’s original theory of conversation improve its coherence and provide adequate methodological tools for a comprehensive model of irony, deception and humor in multi-party interactions, and also for teasing out subtypes of each of these phenomena. Questions regarding the compatibility of this model with experimental findings concern such issues as the relation of irony and deception to Theory of Mind, and the impact of “humor for humor’s sake” on hearers’ opinions. Although these issues are not addressed in Dynel’s philosophically-oriented framework, they are not necessarily incongruent with her perspective.
Diet selection and habitat use by the mountain vizcacha (Lagidium viscacia) in the Southern Andean Precordillera (Argentina)
Authors: Puig Silvia , Rosi María I. , Videla Fernando , Seitz Viviana P. 
Published: November 2019

Abstract

Lagidium viscacia is considered as a fragile species with patchy distribution, a strict habitat specialist and an obligatory diet specialist. The Southern Andean Precordillera constitutes an interesting environment to analyze the species’ presence across the altitudinal gradient. Diet selection and habitat use were studied in the summit plateau, characterized by rigorous conditions and vegetation representative of the Southern Puna. Pellet groups were counted in transects perpendicular to rock formations, and diet and vegetation were seasonally analyzed using microhistological analysis and point-quadrat transects. Vizcachas were strictly associated with rock formations at middle and high altitudes, with higher occurrence on the mountain summit where grasslands surrounded the rock formations. Vizcachas avoided shrubs associated with rock formations and preferred grasses on sandy soils. Phenological changes slightly affected the selective diet that involves a considerable search effort and risky feeding activity. Puna grasslands constituted attractive feeding places where L. viscacia’s activity decreased with distance from rock shelters as expected for a central-place forager. Habitat partitioning allows coexistence with Ctenomys mendocinus, despite the high dietary overlap between these central-place species. The high mobility and broad diet of Lama guanicoe reduce the competition risk. Lepus europaeus preferred shrubs and forbs, determining a discrete dietary overlap with vizcachas.
