Published: May 2019

Abstract
Currently, ohmic heating is a method with a wide potential as an alternative thermal process in the industry. However, the success of this method depends on the rate of the generated heat by the right material’s selection and its geometry. Due to its complexity, the heating systems are usually modeled by computational fluid dynamics (CFD) or finite element method (FEM). However, in this paper, an alternative model representation was used, and this model does not consider the temperature gradients and uses thermal resistance and capacitance as steady-state and transient analog parameters. The parameters are calculated using matlab considering the geometry, as well as the electrical and thermal properties of the material to heat. The proposed circuit is solved by applying the Laplace transform. Finally, the temperature performance of the model and the experimental system are compared with noncontrolled and controlled experiments.

Published: May 2019

Background/aimsAlthough measurements of the Bruch’s membrane opening minimum rim width (BMO-MRW) and retinal nerve fibre layer thickness (RNFLT) with optical coherence tomography (OCT) have been widely adopted in the diagnostic evaluation of glaucoma, there is no consensus on the diagnostic criteria to define BMO-MRW and RNFLT abnormalities. This study investigated the sensitivities and specificities of different diagnostic criteria based on the OCT classification reports for detection of glaucoma.Methods340 eyes of 137 patients with glaucoma and 87 healthy individuals, all with axial length ≤26mm, had global and sectoral BMO-MRW and RNFLT measured with Spectralis OCT (Heidelberg Engineering). Six diagnostic criteria were examined: global measurement below the fifth or the first percentile; ≥1 sector measurement below the fifth or the first percentile; superotemporal and/or inferotemporal measurement below the fifth or the first percentile. The sensitivities and specificities of BMO-MRW/RNFLT assessment for detection of glaucoma (eyes with visual field (VF) defects) were compared.ResultsAmong the six criteria examined, superotemporal and/or inferotemporal measurement below the fifth percentile showed the highest sensitivities and specificities for glaucoma detection. Abnormal superotemporal and/or inferotemporal RNFLT attained a higher sensitivity than abnormal superotemporal and/or inferotemporal BMO-MRW to detect mild glaucoma (mean VF MD: −3.32±1.59 dB) (97.9% and 88.4%, respectively, p=0.006), and glaucoma (mean VF MD: −9.36±8.31 dB) (98.4% and 93.6%, respectively, p=0.006), at the same specificity (96.1%).ConclusionsSuperotemporal and/or inferotemporal RNFLT/MRW below the fifth percentile yield the best diagnostic performance for glaucoma detection with RNFLT attains higher sensitivities than MRW at the same specificity in eyes without high myopia.

ObjectiveTo identify and synthesise existing literature exploring the impact of relational and informational continuity of care on preferred place of death, hospital admissions and satisfaction for palliative care patients in qualitative, quantitative and mixed methods literature.DesignA mixed methods rapid review.MethodsPUBMED, PsychINFO, CINAHL were searched from June 2008 to June 2018 in order to identify original peer reviewed, primary qualitative, quantitative or mixed methods research exploring the impact of continuity of care for people receiving palliative care. Synthesis methods as outlined by the Cochrane Qualitative and Implementation Methods Group were applied to qualitative studies while meta-analyses for quantitative data were planned.OutcomesThe impact of interventions designed to promote continuity of care for people receiving palliative care on the following outcomes was explored: achieving preferred place of death, satisfaction with care and avoidable hospital admissions.Results18 eligible papers were identified (11 qualitative, 6 quantitative and 1 mixed methods papers). In all, 1951 patients and 190 family caregivers were recruited across included studies. Meta-analyses were not possible due to heterogeneity in outcome measures and tools used. Two studies described positive impact on facilitating preferred place of death. Four described a reduction in avoidable hospital admissions. No negative impacts of interventions designed to promote continuity were reported. Patient satisfaction was not assessed in quantitative studies. Participants described a significant impact on their experiences as a result of the lack of informational and relational continuity.ConclusionsThis rapid review highlights the impact that continuity of care can have on the experiences of patients receiving palliative care. The evidence for the impact of continuity on place of death and hospital admissions is limited. Methods for enhancing, and recording continuity should be considered in the design and development of future healthcare interventions to support people receiving palliative care.
Factors of importance for reducing fatigue in persons with rheumatoid arthritis: a qualitative interview study
Authors: Feldthusen Caroline , Mannerkorpi Kaisa 
Published: May 2019

ObjectivePhysical activity plays an important role in the treatment of persons with rheumatoid arthritis (RA) and is the non-pharmacological intervention with the strongest evidence to reduce fatigue. However, physical activity can be challenging for persons who are fatigued. The aim of this study was to investigate factors of importance for reducing fatigue in persons with RA.DesignThis is a qualitative interview study based on semistructured, indepth individual interviews. Interviews were analysed using qualitative content analysis.ParticipantsParticipants were 12 people with RA recruited from a previous randomised controlled trial of a person-centred treatment model focusing on health-enhancing physical activity and daily balance to lessen fatigue in persons with RA.SettingInterviews were conducted in a hospital setting.ResultsThe analysis resulted in one theme:an intellectual and embodied understanding that sustainable physical activity is important to handle fatigue. This included five categories describing barriers and facilitating factors for sustainable physical activity:mentally overcoming the fatigue in order to be active,making exercise easy,reaching for balance,receiving support to be physically activeanddealing with RA disease to be physically active.ConclusionThe participants in this study expressed that physical activity was important in handling fatigue, but also that this insight could only come from personal experience. The use of a person-centred ethic in physiotherapy coaching for patients with fatigue appears to promote sustainable physical activity behaviours by facilitating patients’ resources to overcome barriers to physical activity.

Background and PurposeLiquid embolic agents (LEAs) are the determinant tool for successful embolization of cranial arteriovenous shunts. There are few currently available LEAs. The aim of the study was to summarize our initial experience with a recently introduced non-adhesive ethylene vinyl alcohol (EVOH) copolymer based LEA (Menox 18) in the endovascular treatment of cerebral arteriovenous malformations.MethodsFrom April 2018 to November 2018, 24 patients harboring cerebral arteriovenous malformations underwent endovascular embolization with Menox 18. Clinical features, angiographic results, procedural details, complications, and follow-up details were prospectively collected and retrospectively analyzed.ResultsCurative embolization in one endovascular session was achieved in 14/24 (58.3%) of the treated patients. Partial embolization was achieved in 10 patients (42.6%) in whom staged treatment with radiosurgery or microsurgical resection was planned. No mortality was recorded in our series. Clinical complications after embolization occurred in 1/24 (4.66%) patients. No technical complications were notedConclusionsOur pilot study suggests that the Menox embolization system offers similar technical and clinical results in comparison with the other currently available LEAs. Further studies with larger cohorts and long term follow-up data are needed to fully evaluate its efficacy

Published: May 2019

ObjectiveTo identify, appraise and synthesise studies that have examined the degree to which new workers are at an elevated risk of work-related acute injuries and musculoskeletal (MSK) injuries.MethodWe searched three relevant electronic databases for studies published between 1995 and early 2018. Fifty-one studies using multivariate analyses met our relevance and quality appraisal criteria. These studies examined two different work outcomes: acute injuries (eg, cuts, burns and falls) and MSK injuries (eg, repetitive strain).ResultsIn four of six studies looking at acute work injuries, new workers were found to be at an elevated risk of injury (ie, moderate supportive evidence of new worker risk). In another six studies looking at MSK symptoms, injuries or disorders, evidence of an elevated risk among new workers was insufficient or limited.ConclusionsOur review has potential implications for the prevention of work injuries, providing policy-makers and workplace parties with supportive evidence about the importance of prevention efforts focused on new workers, such as developing workplace policies that emphasise hazard exposure reduction, hazard awareness, hazard protection and worker empowerment.

ObjectiveTo assess tobacco promotion intensity, retailer behaviours and tobacco company efforts to link retailer marketing to online channels.MethodsWe completed an audit of tobacco advertisements and promotions at 1000 randomly selected cigarette retailers in Denpasar, Bali, Indonesia that included an observation checklist, digital photos and structured interviews with retailers. We then calculated the tobacco promotion index for each retailer and made comparisons based on store types. Next, we conducted a photo analysis from 100 randomly selected retailers to explore links to online channels and other promotional cues to engage young people.ResultsMini-markets have both the highest total number of promotions and the highest indoor promotion index with a mean score of 5.1 and 3.7, respectively. Kiosks have the highest outdoor promotion index with a mean score of 1.6. Most of the retailers (98.9%) displayed cigarettes, more than half of kiosk retailers (54.8%) and mini-market retailers (56.3%) admitted selling cigarettes to young people, and 74% of kiosk retailers sell single stick cigarettes. We found links to online marketing, including two hashtags and a company website. Promotional materials also included youth-focused content such as English taglines, new products and small packs.ConclusionTobacco companies in Indonesia have strategically differentiated their advertisements based on retailer type and have bridged conventional retailer marketing to online channels. Reforming Indonesian tobacco laws to include bans on single sticks and small pack sales, point-of-sale advertising, including displays, and enforcement of laws on sales to minors is urgently required.
Butting out: an analysis of support for measures to address tobacco product waste

Published: May 2019

BackgroundCigarette butts are ubiquitous litter items, causing major environmental damage and imposing significant clean-up costs. Tobacco companies frame smokers as both the cause of this problem and the source of its solution. However, an extended producer responsibility perspective challenges this view and holds tobacco companies to account for the full life cycle costs of tobacco product waste (TPW).MethodsUsing an online cross-sectional survey of 396 New Zealand smokers and 414 non-smokers, we estimated awareness of TPW, attribution of responsibility for TPW and support for interventions to reduce TPW. Descriptive analyses and logistic regression models examined associations between demographic attributes and smoking behaviours, and perceptions of TPW and potential solutions to this problem.ResultsMost respondents saw butt litter as toxic to the environment and held smokers primarily responsible for creating TPW. However, when knowledge of butt non-biodegradability increased, so too did the proportion holding tobacco companies responsible for TPW. Changes to product design, fines for littering and expanded smoke-free spaces were considered most likely to reduce TPW. Smokers and non-smokers held different views on measures to address TPW, with smokers favouring more educative approaches and non-smokers more restrictive policies.ConclusionsStrategies to increase awareness of tobacco companies’ role in creating TPW could foster political support for producer responsibility measures that require the industry to manage TPW. Nevertheless, policy measures should continue to foster smoking cessation and decrease uptake, as reducing smoking prevalence presents the best long-term solution to addressing TPW.

The purpose of the paper is to provide a detailed overview of the methods of indexing and categorizing data generated to solve problems in a complex and multifaceted field of knowledge related to the application of nanotechnology. Analysis of the capabilities and restrictions of various categorization methods are applied to the issues of the subject field, starting with simple classification schemes and up to high level ontologies. The content of integrating methods and approaches developed in many natural sciences is considered: life science, chemistry, material science, etc. The main restriction of the currently applicable ontologies and vocabularies has been identified — a primary focus on the tasks of bio- and medical informatics. It is shown that the way to overcome them includes the adoption of a new system for describing nanomaterials proposed in the CODATA-VAMAS international project. The overview shows how the extreme broadness and continuous evolution of the subject field are reflected in the means of data categorization. It is shown that the most developed of them can serve as a basis for building a knowledge base. The prospective tasks of nanoinformatics are stated required to be solved to cover fundamentally unlimited classes of materials, their properties and fields of application.
Efficient Checkpointing with Recompute Scheme for Non-volatile Main Memory

Published: May 2019

Future main memory will likely include Non-Volatile Memory. Non-Volatile Main Memory (NVMM) provides an opportunity to rethink checkpointing strategies for providing failure safety to applications. While there are many checkpointing and logging schemes in the literature, their use must be revisited as they incur high execution time overheads as well as a large number of additional writes to NVMM, which may significantly impact write endurance.
In this article, we propose a novel recompute-based failure safety approach and demonstrate its applicability to loop-based code. Rather than keeping a fully consistent logging state, we only log enough state to enable recomputation. Upon a failure, our approach recovers to a consistent state by determining which parts of the computation were not completed and recomputing them. Effectively, our approach removes the need to keep checkpoints or logs, thus reducing execution time overheads and improving NVMM write endurance at the expense of more complex recovery. We compare our new approach against logging and checkpointing on five scientific workloads, including tiled matrix multiplication, on a computer system model that was built on gem5 and supports Intel PMEM instruction extensions. For tiled matrix multiplication, our recompute approach incurs an execution time overhead of only 5%, in contrast to 8% overhead with logging and 207% overhead with checkpointing. Furthermore, recompute only adds 7% additional NVMM writes, compared to 111% with logging and 330% with checkpointing. We also conduct experiments on real hardware, allowing us to run our workloads to completion while varying the number of threads used for computation. These experiments substantiate our simulation-based observations and provide a sensitivity study and performance comparison between the Recompute Scheme and Naive Checkpointing.

Mechanical ventilation (MV) is a life-saving intervention, yet with prolonged MV (i.e., ≥6 h) there are time-dependent reductions in diaphragm blood flow and an impaired hyperemic response of unknown origin. Female Sprague-Dawley rats (4–8 mo, n = 118) were randomized into two groups; spontaneous breathing (SB) and 6-h (prolonged) MV. After MV or SB, vasodilation (flow-induced, endothelium-dependent and -independent agonists) and constriction (myogenic and α-adrenergic) responses were measured in first-order (1A) diaphragm resistance arterioles in vitro, and endothelial nitric oxide synthase (eNOS) mRNA expression was quantified. Following prolonged MV, there was a significant reduction in diaphragm arteriolar flow-induced (SB, 34.7 ± 3.8% vs. MV, 22.6 ± 2.0%; P ≤ 0.05), endothelium-dependent (via acetylcholine; SB, 64.3  ± 2.1% vs. MV, 36.4 ± 2.3%; P ≤ 0.05) and -independent (via sodium nitroprusside; SB, 65.0 ± 3.1% vs. MV, 46.0 ± 4.6%; P ≤ 0.05) vasodilation. Compared with SB, there was reduced eNOS mRNA expression ( P ≤ 0.05). Prolonged MV diminished phenylephrine-induced vasoconstriction (SB, 37.3 ± 6.7% vs. MV, 19.0 ± 1.9%; P ≤ 0.05) but did not alter myogenic or passive pressure responses. The severe reductions in diaphragmatic blood flow at rest and during contractions, with prolonged MV, are associated with diaphragm vascular dysfunction which occurs through both endothelium-dependent and endothelium-independent mechanisms.NEW & NOTEWORTHY Following prolonged mechanical ventilation, vascular alterations occur through both endothelium-dependent and -independent pathways. This is the first study, to our knowledge, demonstrating that diaphragm arteriolar dysfunction occurs consequent to prolonged mechanical ventilation and likely contributes to the severe reductions in diaphragmatic blood flow and weaning difficulties.

Published: May 2019

We investigated the effect of temperature increase on mitochondrial fatty acid (FA) and carbohydrate oxidation in the slow-oxidative skeletal muscles (soleus) of rats. We measured mitochondrial respiration at 35°C and 40°C with the physiological substrates pyruvate + 4 mM malate (Pyr) and palmitoyl-CoA (PCoA) + 0.5 mM malate + 2 mM carnitine in permeabilized myofibers under nonphosphorylating ([Formula: see text]) or phosphorylating ([Formula: see text]) conditions. Mitochondrial efficiency was calculated by the respiratory control ratio (RCR = [Formula: see text]/[Formula: see text]). We used guanosine triphosphate (GTP), an inhibitor of uncoupling protein (UCP), to study the mechanisms responsible for alterations of mitochondrial efficiency. We measured hydrogen peroxide (H2O2) production under nonphosphorylating and phosphorylating conditions at both temperatures and substrates. We studied citrate synthase (CS) and 3-hydroxyl acyl coenzyme A dehydrogenase (3-HAD) activities at both temperatures. Elevating the temperature from 35°C to 40°C increased PCoA-[Formula: see text] and decreased PCoA-RCR, corresponding to the uncoupling of oxidative phosphorylation (OXPHOS). GTP blocked the heat-induced increase of PCoA-[Formula: see text]. Rising temperature moved toward a Pyr-[Formula: see text] increase, without significance. Heat did not alter H2O2 production, resulting from either PCoA or Pyr oxidation. Heat induced an increase in 3-HAD but not in CS activities. In conclusion, heat induced OXPHOS uncoupling for PCoA oxidation, which was at least partially mediated by UCP and independent of oxidative stress. The classically described heat-induced glucose shift may actually be mostly due to a less efficient FA oxidation. These findings raise questions concerning the consequences of heat-induced alterations in mitochondrial efficiency of FA metabolism on thermoregulation. NEW & NOTEWORTHY Ex vivo exposure of skeletal myofibers to heat uncouples substrate oxidation from ADP phosphorylation, decreasing the efficiency of mitochondria to produce ATP. This heat effect alters fatty acids (FAs) more than carbohydrate oxidation. Alteration of FA oxidation involves uncoupling proteins without inducing oxidative stress. This alteration in lipid metabolism may underlie the preferential use of carbohydrates in the heat and could decrease aerobic endurance.
