Organic Bio-Electronics: Bridging The Gap Between Natural and Artificial Materials for Bio-Electronics Applications
Authors: Omokhunu Godspower W. , Bach Christian
Published: February 2019

This paper aims to review current research and advancement in technology in organic bioelectronics and to reinvestigate the relationship between organic bioelectronics materials, properties, and application. A comprehensive literature review on organic bioelectronics and its dependent variables created a theoretical foundation for the paper. Using the review-centric theory, a model was developed and presented to encapsulate highly dynamic interaction of organic bioelectronics, synthetic and natural material sources that can be employed in present innovations and its implications on modern technologies. The model highlights the relationship between organic bioelectronics and its four main drivers namely, synthetic material (Piezoelectric energy harvesters), natural materials (electric organs), application (bio-devices, sensors, nanogenerators) and properties. Limitations to this research include; availability of raw materials in appropriate amounts, problems associated with interfacing natural with synthetic materials, maintenance of bioelectronics devices in living organisms and design methods for a variety of specific devices. The empirical data is limited to 4 dependent variables which do not present a conclusive theory about organic bioelectronics. In this review, we explored the possibility of interfacing synthetic material (PVDF) and a natural material (electric organ of Electrophorus electricus) by reviewing their properties, fabrication methods to create a composite that has application in a variety of bioelectronics devices.

This paper studied the chemical composition of cultivated 3, 4 and 5 year-old highland bamboo (Y. alpina) which were classified into three position (top, medium and bottom) to determined the main compositions especially cellulose, lignin, extractive and ash content. From all culms representative samples were converted to the required size of wood chips to prepared sample for chemical testing. Then the specimens prepared from bottom, middle and top portions for the three ages were used to determine the chemical properties in accordance to American Society for Testing and Materials (ASTM) standards except for cellulose test determined according to Kurschner and Hoffer method. All parameters in the experiment were expressed by percent based on dry basis. From this research, we have found small but significant increases in mean cellulose content from the base to the top of the culm at all three ages. The lignin content in Y. alpina species of bamboo is in the ranged of 23.04 to 30.03%. The mean values of the chemical constituents in 3, 4 and 5- year-old culms were 51.83, 54.94 and 49.78% for cellulose content, 28.28, 24.99 and 24.53% for lignin content, 7.8, 10.09, and 9.54% for alcohol-toluene extractive, respectively. In general, the comprehensive knowledge of the chemical components in the bamboo species will facilitate the use of the materials in the forestry industrial sector and help to enhance their utilization in the chemical and bio-chemical related industry.

What Problem is Being Solved? ‘Preventability’ and the Case of Pricing for Safety and Quality
Authors: Duckett Stephen
Published: February 2019

One of the critical issues facing healthcare systems internationally is to improve safety of care. Unfortunately, safety discussions, both in hospitals and in policy documents, often quickly turn to identifying and acting on ‘preventable’ mishaps. But preventability is a slippery concept, which this paper discusses. A contemporary policy response is to introduce financial incentives in hospitals and/or states to improve safety, proposed for national implementation in Australia from 1 July 2017. This has the potential to change the internal dynamic of hospitals to enhance the focus on safety. The implications for hospitals of this change are also discussed.

Health Systems in Australia and Four Other Countries: choices and challenges
Authors: Martins Jo M
Published: February 2019

The purpose of health systems is the pursuit of healthy lives. The performance of the Australian health system over the last decade is compared with the United Kingdom and its three other offshoots: the United States, Canada and New Zealand. In the first instance, system performance is assessed in terms of threats to healthy lives from risk factors and changes that have taken place during the decade. In view of the emphasis of the five systems on the return to health after trauma and illness, and the human-resource intensity of health services, an appraisal is made of changes in the number of the major health professionals in relation to the growing populations. Then related changes in hospital, medical practitioner and dentist services are assessed. Changes in pharmaceutical drug prescriptions in Australian are also examined. The levels of national expenditures arising from the provision health services are then considered in the context of the costs of administration of the varied organisational modes, use of expensive medical technologies, pharmaceutical drug consumption and remuneration of health professionals. Finally, health outcomes in Australia and the other four countries are assessed in accordance with their human development level, life expectancy, potential years of life lost from different causes, as well as healthy life expectancies. Further, gaps in health and life expectancy of Indigenous people in the United States, Canada, New Zealand and Australia are reviewed, as well as health and survival inequalities among people in different social strata in each country.

Healthcare System Restructuring in New Zealand: problems and proposed solutions
Authors: Gauld Robin
Published: February 2019

New Zealand’s healthcare system is, like most, in a continual process of restructuring and change. While the country has endured several major system-wide changes in recent decades, more recent change has been incremental and evolutionary. Current changes are in response to a set of challenges, which are not unique to New Zealand. This article overviews the New Zealand healthcare system. It then describes a series of problems facing the system and proposed solutions. These include the need for team care, providing services closer to patients’ homes, focusing on a population of interest, connecting up the system, and engaging patients more closely in care design and delivery.

Identifying and Ranking Areas of Relative Need for New Public Dental Clinics Using a State-of-the-Art Data Simulation Approach
Authors: Dudko Yevgeni , Robey Dennis E , Kruger Estie , Tennant Marc
Published: February 2019

Background: Lower socioeconomic groups and country residents are more likely to experience dental disease. Previous research has found that it is generally more cost effective to provide subsidised dental care through publically employed dentists when compared to subcontracting the work out to the private sector.

Objective: The primary objective of this study was to identify and rank areas of relative need for new public dental care facilities across Australia. The secondary objective was to gauge how many of these areas arelocated in the vicinity of an existing public hospital (medical) with a view to utilise existing infrastructure for future service rollout.

Methods: Usual resident population, employment status and socioeconomic distribution data was downloaded from the Australian Bureau of Statistics website at Statistical Area 1 level. A mathematical weighing formula was applied to those variables, which subsequently allowed for ranking of the results based on magnitude of the product values. The findings were considered in terms of proximity to existing public health infrastructure.

Results: A total of 49 SA1 areas were identified and preselected as potential sites for new public dental clinics across Australia. Eighty per cent of the identified areas of relative need were located outside metropolitanareas. Fifty per cent of those were found to be in close proximity to an existing public hospital (medical).

Conclusion: Offering subsidised dental care through existing public hospitals may be an option. Such an approach has a potential to improve access to subsidised dental care in regional centres while minimising capitalexpenditure on infrastructure.

Entry Points to the Health System: a review of the emerging community models for management of non-life threatening urgent conditions relevant to Australia
Authors: Adie John , Graham Wayne , Wallis Marianne
Published: February 2019

Problem: The number of presentations to Emergency Departments (EDs) is increasing at levels above population growth rates and these increases are becoming unsustainable.

Objective: To review evidence for emerging entry points to the health system for patients with non-life threatening urgent conditions (NLTUC) in order to consider more effective healthcare services in Australia.

Methods: An in-depth review of the Emerald, Medline, CINAHL, Web of Science, Proquest Business and Medical databases from January 2005 to April 2016 matching ‘acute care’ or ‘urgent care’ with general practice andother health providers found thirteen entry point models with five currently relevant to Australia.

Results: Studies examining five emerging entry points were found including urgent care community pharmacy, new prehospital practitioner community care, advanced nurse enhancement of primary care, designated urgent care clinics and integrated primary care centers. Evidence for these emerging models of community healthcare is presented including emerging initiatives, cost implications, subsequent admission to hospital, satisfaction, mortality, care, treatment time, subsequent referrals, testing and health outcomes.

Conclusion: These emerging models of community healthcare need to be trialed and studied in the Australian context to evaluate whether they provide patients with NLTUC with a safe cost-effective option with similar outcomes to EDs. Implementation of these models can be examined further to determine their effectiveness in potentially reducing the increasing rate of presentation to EDs.

Publish or Perish: Perspectives from the APJHM for health managers
Authors: Briggs David
Published: February 2019

The term ‘publish or perish’ is familiar to most of us engaged in some way in academia and reflects the mantra that to have a successful career as a teacher, researcher and all-round academic wanting to be recognised as an expert in your discipline requires you to be well and regularly published. This directive also has added implications to not publish in ‘any journal’ but in ones that have high impact factors. This suggests that they have recognised quality articles that have been peer reviewed, have rigour in the editorial process and, therefore are difficult to obtain publication in, particularly for students and emerging researchers. Progression of careers are dependant on this mantra and, we all want to ensure that the quality of our research, our science is of the best standard.....
Factors Affecting Motivation and Retention of Village Health Workers and Recommended Strategies: a systematic review from 11 developing countries
Authors: Tshering Dolley , Tejativaddhana Phudit , Briggs David , Wangmo Neyzang
Published: February 2019

Introduction: Motivation and retention of village health workers (VHWs) are crucial for the continuity, sustainability, and success of health programs. VHWs are the first point of contact for rural communities, providing health services to improve access and health coverage which, for a variety of logistical reasons, cannot be reached by the district health care system. Thus VHWs are critical for ultimately ensuring universal health coverage. However, systematic review revealed that there are numerous factors that affects their motivation and retention, leading to high dropout rates and hampering the delivery of health services to the community. This review intends to examine contextual factors affecting motivation and retention of VHWs in their roles and identify recommendations and strategies to motivate and retain them in the systems.

Method: Five electronic databases and two search engines were accessed. Nineteen studies met the inclusion criteria for the final review. An in-depth reading of all the articles was undertaken to gather and compile the relevant themes. Content analysis was done based on the list of specific categories that are relevant to motivation and retention. 

Result: Findings from the systematic review revealed different levels of factor affecting motivation and retention of village health workers. It was finally contextualized and categorized into four main domains such as individual, family, social or community and organizational or systems levels. Financial incentives under the organizational factors was highlighted for the demotivation and the discontentment for the VHWs.

Conclusion: Financial factors under the organization were often key in the studies reviewed. However, there were also many other factors, sometimes surprising or unintuitive, influencing the motivation and retention of village health workers.

Authors: James Christopher , Delzoppo Carmel , Tibballs James , Namachivayam Siva , Butt Warwick
Published: February 2019

Objective: To determine the frequency, nature and consequence of adverse events sustained by children admitted to a combined general and cardiac paediatric intensive care unit (PICU).

Design: Retrospective analysis of data collected between January 1st 2008 and December 31st 2017 from PICU.

Setting: The Royal Children’s Hospital, a paediatric tertiary referral centre in Melbourne, Victoria, Australia. The PICU has thirty beds.

Results: During the study period, PICU received 15208 admissions, of which 73% sustained at least one adverse event with a frequency of 67 adverse events per 100 PICU-days and 3 per admission. One adverse event was sustained for every 35 hours of care. The risk of an adverse event was highest in children less than a month of age, or if mechanically ventilated, a high Pediatric Index of Mortality (PIM2) score, longer PICU length of stay, had a pre-existing disability or a high risk adjustment for congenital heart surgery (RACHS) score. Those patients who sustained an adverse event, as compared to those who did not, were mechanically ventilated for longer (80 hrs Vs. 7 hrs, p=<0.001), had a longer PICU length of stay (131 hrs Vs. 35 hrs, p=<0.001), had a longer hospital length of stay (484 hrs Vs. 206 hrs, p=<0.001) and had a higher mortality rate (3% vs. 0.1%, p=<0.001).

Conclusion: Whilst admission to PICU is an essential aspect of care for many patients, the risk of adverse events is high and is associated with significant clinical consequences. Monitoring of adverse events as part of quality improvement enables targeted intervention to improve patient safety.

Authors: Karalis Elina , Barbery Gaery
Published: February 2019

Background: Implementing high reliability organization principles can enhance quality and safety in healthcare. Evidence-based instructions on how to effectively change the organizational culture in healthcare setting are required.

Objectives:  A systematic review investigating methods, facilitators, and barriers to assist healthcare organizations in becoming a high reliability organization.

Method: Literature searches were performed in PubMed, MEDLINE, CINAHL-Complete, EMBASE, and Scopus for articles published between January 2012 and October 2017. The included articles were case reports, case studies, and protocol development studies on implementing high reliability organization principles. The articles were appraised using a modified Critical Appraisal Skills Programme tool. Thematic synthesis was conducted using manual coding. 

Results: Of the 14 eligible articles nine were case studies, four were case reports, and one was a framework development report. The study populations varied from whole healthcare systems to a single department of a hospital. The most common methods were supportive leadership, staff education, and analysing the safety events and sharing the knowledge. Cost was one of the barriers. Remuneration came in reduction of safety events and costs avoided.

Conclusion Implementing high reliability organization principles in healthcare settings is slow and challenging, but doing so improves quality, resilience, and safety, thus increasing productivity.

Authors: Pain Tilley , Patterson Sarah , Kuipers Pim , Cornwell Petrea
Published: February 2019

Background: Increasing demand for allied health services is driving workforce redesign towards greater productivity within budgetary constraints. To date, there has been limited research into workforce redesign tools at an organisational level. The aim of this article was to evaluate an implementation of The Calderdale Framework for state-wide service delivery workforce redesign within allied health settings across Queensland.

Method: A multi-phase methodology with mixed methods of data collection was used. This included analysis of documents, staff surveys, and semi-structured, in-depth interviews with staff from work units utilising the Framework across the state.

Findings: The primary mechanisms for implementation were staff training and provision of centralised resources. Across the state, all health services engaged in training and most completed associated workforce redesign projects. However, the number and type of projects varied across the state as did the successful projects. Feedback from staff indicated the structured nature of the framework was viewed positively, but was time intensive to perform. Local contextual factors heavily influenced workforce redesign success.

Conclusion: Key factors pertaining to state-wide workforce redesign include: providing coordinated and centralised systems to support staff, ensuring adequate training, prioritising the development of key local staff, and proactively managing local contextual factors.

Published: February 2019

Cityscape identity might be objective and subjective. Still, it is more often analysed from person’s perspective, and analysis of urban fabric itself is not considered sufficiently. Thus, this research aims to find out if fractal analysis method could be used to fill that gap. Kaunas city was chosen for the case study. The research was conducted in three stages: qualitative assessment (designation of the zones with different semantic load in Kaunas), quantitative assessment (calculation of fractal indexes of panoramic and streetscape views from previously established zones), and comparison of these approaches. To sum up, the research confirmed that there is a relationship between the results of different approaches. Thus, fractal analysis could be used as one of the tools for quantitative assessment of cityscape identity.
The Demonstration Model of an Electromagnetic Accelerator Gun
Authors: Molnar Andras
Published: February 2019

These days a lot can be heard about special weapons which accelerate the projectile not based on the traditional, chemical energy release, but providing the muzzle velocity with the help of electromagnets. In English terminology, many descriptions can be read about these devices, referred to as “coilgun”. There are so many hobbyist and amateurs who make these devices [1,2] and publish their results on the internet [3,4]. The purpose of the project is dual. On one hand, features, advantages, disadvantages and the limits of the electromagnetically accelerated weapons can be found by building an experimental tool. On the other hand, it was intended to point out the fact that anybody can build such a tool using commercially available commercial components. Although the muzzle energy of the device presented in this paper is not more than 6.8J, but it can cause serious injury. The paper also points out that in a similar way, still not using special components, a weapon can be made with a larger (10-20J) muzzle energy.

Authors: Mroczek Bożena , Lichota Małgorzata , Trybek Grzegorz , Grzywacz Anna
Published: February 2019

Background/Aim: The loss of teeth and its consequences for health, as well as the psychological discomfort it entails, have a negative impact on both self-reported health state and quality of life (QoL). Dental implantation aims to increase patients' health and satisfaction and to improve all aspects of QoL. The purpose of this cross-sectional correlational study was to compare the patients' QoL before and after dental implantation. Material and Methods : The study comprised 62 patients aged between 24 and 77, including 28 (45.16%) women and 34 (54.84%) men, who reported to a private dental clinic in Szczecin, Poland to replace missing teeth with implants. The survey was carried out twice: prior to the treatment, when the decision to use implants had been made, and three months after implantation, during the first check-up. QoL was measured using the 36-Item Short Form Health Survey (SF-36), and sociodemographic data were collected using a questionnaire of the author. Results: There were statistically significant differences between the assessment of health and QoL before and after implantation treatment. Both the patients' health and comfort of life improved after therapy. Conclusions: Replacement of missing teeth with dental implants brought overall improvement in patients' QoL, social comfort, and general health.

Background/Aim: Implant treatment expands extensively the possibilities of prosthetic treatment, which provide benefits, bigger comfort as well as general improvement of the patient's life quality. In cases with no possibility of implantation, it is possible to improve conditions by using modern methods for bone tissue repair. One of factors important for the long-term success is proper oral hygiene, as well as raising awareness of its importance to patients. The aim of the paper is to present a patient rehabilitated with multiple implants and followed-up for a five-year period, and to point out the importance of raising patient's awareness and motivation in order to preserve the results of the treatment. Case Report: A 31-year-old patient was admitted to the oral surgery clinic for rehabilitation of a poor oral health status. After taking history, clinical examination and additional analysis, the following treatment plan was suggested: to remove impacted upper canines and to put an implant supported by fixed prosthesis in the upper jaw, to make two implants supported by bridges laterally and one dental supported by bridge in the inter-canine sector in the lower jaw. The treatment was carried out in several stages that involved extraction of residual roots and impacted teeth, augmentation of bone defects with bone substitutes and bio-absorbable membranes, placing implant, and prosthetic rehabilitation. By verbal communication with the patient, we pointed out the importance of proper oral hygiene and regular check-ups. The five year follow-up showed the absence of factors that could adversely affect the success of the treatment, and the patient was still highly motivated to maintain proper oral hygiene. Conclusions: It is possible to achieve predictable results in complex cases by using a multiphase prosthetic treatment supported by implants. Concerning a long-term success, motivation, proper information and patient's willingness to cooperate play an important role.
Mini-implants and zirconium crowns in treating congenitally missing maxillary lateral incisors: Case report
Authors: Hegazi Hend
Published: February 2019

Background/Aim: A problem of congenitally missing lateral incisors is frequently encountered in dentistry, with several available treatment modalities, the choice depending on each case. Case Report: A young female patient with bilateral missing lateral incisors was in need for dental treatment for esthetics. She had spacing among the upper anterior teeth with class I molar relationship. Orthodontic space creation was carried out followed by two-piece mini dental implant placement. Two-stage protocol was followed. After osseointegration, implants were exposed. Healing collars were installed to allow mucosal healing. Closed tray implant level impression was taken. Zirconium crowns were chosen for optimum esthetic results. Conclusions: Mini-implants can be used successfully for restoring congenitally missing lateral incisors after space opening. Esthetic results can be enhanced using Zirconium crowns.

Long distance dispersal is a key process occurring in plant communities and is particularly important for pioneer species like sea-buckthorn (Hippophaë rhamnoides L.) which survival strongly depends on colonizing newly created post-disturbance habitats. Sea-buckthorn, a cluster-forming shrub, is commonly used in Poland in the reclamation of soil-less areas devastated the by mining industry and for these areas a generative expansion of planted populations is usually observed. The main objective of this study was to assess the long-distance dispersal of this species in areas previously disturbed by industrial activity. Our observations were made on a 223.75 ha large section of the internal waste heap of the Bełchatów lignite mine, Central Poland. The area was colonized by sea-buckthorn specimens originating from a population planted on the nearby external waste heap. During the search for newly established sea-buckthorn clusters, their position and size were recorded and the preferences for specific site conditions were assessed using the Ivlev’s electivity index. New specimen were observed at distances between 600 m and 3600 m from their potential seed source. The mean cluster density was 1.37 ha−1. The observed pattern of long distance dispersal is linked with to behavior of frugivorous birds. The largest cluster densities were observed along ditches (9.83 ha−1) and on open areas with less developed plant cover, while the lowest cluster density occurred in afforested areas (0.51 ha−1). Poor sandy substrate reduced the probability of plant establishment compared to richer loamy sands. There appeared to be no influence of slope aspect on the probability of sea-buckthorn establishment.

Evolutionary changes in European small mammals during the second half of the Middle Pleistocene, from the Likhvin (Holsteinian, Hoxnian) Interglacial (MIS 11) to the beginning of the Mikulino (Eemian) Interglacial (MIS 5e), that is between 424 ka BP and 130 ka BP were traced. Trends in evolutionary change were documented, and East European and West European faunas were compared. An integrated analysis of available theriological, geological, and geochronological data for the second half of the Middle Pleistocene in Europe has shown marked changes in the small mammal fauna throughout the period under consideration and provided information on the climate and environments at different time intervals. Changes traceable in the Arvicolinae phyletic lines made a correlation between the West European and East European mammal localities possible. The biostratigraphic scheme of the second half of the Middle Pleistocene has been developed and maps of small mammal localities compiled.
Arsinoitherium (Embrithopoda) and other large mammals and plants from the Oligocene of Tunisia
Authors: Pickford Martin
Published: February 2019

Palaeogene large mammals are poorly represented in Tunisia, in contrast to Morocco, Algeria, Libya and Egypt, where abundant and diverse faunas are known. Oligocene proboscideans have been recorded from four localities in Tunisia (Djebel Bou Gobrine, Oued Bazina, Bled Mellaha and Djebel Touila) but little else from this period is known from the country. For this reason it is worth recording the discovery of an arsinoithere tooth fragment from the divide between Oued Cherichera and Oued Grigema, Central Tunisia. This discovery confirms the presence of continental Oligocene strata in the region, and the palaeodistribution of Arsinoitherium 1,300 km to the north-northwest of its previously established range. Arsinoitheres are now known to have been widespread throughout the Afro-Arabian continent. Although palaeoclimatic data for the Oligocene of Tunisia is still scarce, fossil plants suggest that, during the Oligocene, the country enjoyed a tropical to sub-tropical humid climate, in accordance with the presence of Arsinoitherium, Phiomia and an anthracothere, taxa that are also present in the classic Fayum faunas of Egypt and the Ashawq faunas of Oman.
New hyaenodonts (Ferae, Mammalia) from the Early Miocene of Napak (Uganda), Koru (Kenya) and Grillental (Namibia)
Authors: Morales Jorge , Pickford Martin
Published: February 2019

Recent palaeontological surveys in Early Miocene sediments at Napak (Uganda), Koru (Kenya) and Grillental (Namibia) have resulted in the collection of a number of small to medium-sized hyaenodonts and carnivorans, some of which were poorly represented in previous collections. The present article describes and interprets the hyaenodonts from these localities. The new fossils permit more accurate interpretation of some of the poorly known taxa, but new taxa are also present. The fossils reveal the presence of a hitherto unsuspected morphofunctional dentognathic system in the Hyaenodontidae which is described and defined, along with previously documented dentognathic complexes. Two new tribes, three new genera and one new species are diagnosed.
Everything is a question of time – age of important Quaternary palaeontological finds from Westphalia
Authors: Bertling Markus , Döppes Doris , Rosendahl Wilfried
Published: February 2019

Accelerator mass spectrometry (AMS) was used to establish the age of three mammal specimens from the Quaternary of the Münsterland, North Rhine-Westphalia, Germany. The dated samples represent regionally important finds: The woolly mammoth from Ahlen with an age of 41 ka BP and the musk-ox from Herne with an age of 24 ka BP are typical representatives of the so-called mammoth steppe. The European Bison from Gladbeck with an age of 9.2 ka BP confirms the Early Holocene appearance of this species in Europe.
