Published: June 2017

The detection of human balance functional disorders may provide some kind of awareness or even warning about potential problems for human health both in organs responsible for ensuring the balance function and in organs related to fulfilment of other important life functions. Modern world offers some sophisticated solutions which enable not only determination of the human balance functional capacity but also offer some kind of training environment to provide corresponding rehabilitation. Unfortunately, such systems are very expensive. And this make limitations of their accessibility and practical usability for a wide range of the target group / population. Software solutions, including mobile applications, on the other hand, are incomparably cheaper. However, they do not allow to make precise balance capability measurements, limiting to simplified balance retention simulators.

During implementation of the Latvian National State Research Program VPP INOSOCTEREHI from 2015 to 2017 three human balance capability testing prototypes were developed using a variety of electronic and mechatronic solutions. The last one was successfully approbated during two pilots in Latvian schools in 2016 and demonstrated at the International Invention and Innovation Exhibition MINOX-2016. This paper analyses benefits and disadvantages of approaches used in creating of these prototypes. Besides, authors make initial comparison of developed third prototype version against the BioSway system offered in the market. The paper gives also insight into particular system interface development and new effective graphic portrayal of the balance testing output data, as well as sets the goals for further possible commercialization of the developed balance testing prototype.

Published: June 2017

Nowadays, more and more importance is given to labour protection, health and safety. One of the protective means is suitable clothing. Often workwear serves as a uniform, which characterize the position of the worker and represents the organization. Basically, such types of workwear are sewn or purchased using the procurement procedure. Usually procurement procedure is carried out for the entire sewn product as a whole. When workwear is worked out great importance should be paid to basic fabrics and their protective quality. In order to provide the most suitable choice of the fabric, the procurement procedure of it should be done separately from the sewing service purchase. Fabric production and garment sewing in most cases take place at different companies. In this case, does not always match the probability that the best sewing service provider will offer the best quality fabrics.

Technical specification of fabrics should be worked out very carefully. It should include fabric fibre content, structure characteristics, type of finishing, mechanical and physical properties. Fabrics supplier selection can be made after the applicant submitted fabric technical description, were specifies all nominal values of requested technical characteristics. The procurement procedure must include testing of actual characteristics and its comparison with nominal values.

Field uniform fabrics are analysed as an example in scientific study. The procurement procedure of these fabrics should be especially accurate. During procurement procedure is important to check conformity of supplied fabric directly to offered characteristics.

Published: June 2017

Country's economic potential implies joint capability of the country's economy, its branches and enterprises to carry out production and economic activity, to create goods and services, to supply the demand of the population, to stimulate production and consumption development. Country's economic potential is defined by estimating different economic, social, ecological, scientific and technical, political and other criteria, which, as a rule, are interconnected and correlated. Each of these criteria includes heterogeneous set of economic, financial, social, political, juridical, educational, scientific and innovational, ecological, cultural and other factors, every single of which can consist of independent or indirectly correlated subfactors called indices or indicators. In this work we investigate the problem of estimating economic potentials of groups of countries according to their measurable economic, financial, social and other indicators in order to export bank and other luxurious services. The approach to solving the problem offered in this work is based on the apparat of the theory of inverse and ill-posed problems.

Published: June 2017

The paper focuses on building envelopes for industrial thermal generating units, their efficiency and its increase. Building envelopes made of lightweight heat-resistant concretes are considered most effective from the point of their building construction, maintenance, repair and cost-effectiveness. One of the unresolved problems here is that porous granular materials suitable for use as concrete fillers operating at temperatures over 1000 OC are not industrially manufactured at the moment The article also characterises commonly used heat resistant porous fillers. It indicates that the use of exhaust zeolites is potentially perspective General properties and characteristics of zeolites are also given. The paper demonstrates that it is quite possible to use exhaust zeolites in building envelopes of lightweight heat-resistant concretes. The work describes testing experiments of typical exhaust zeolites (petrochemical and oil refining industries wastes) in Samara region and the Republic of Tatarstan. Their stress-strain properties and chemical compositions as well as X-ray crystallographic analysis (including analysis under high temperature) are presented. They prove that zeolites are heat-resistant and fire-proof because of corundum formation. Phosphate binder was used for tesing in heat-resistant concretes. The composition of the concrete mixture is given in the paper. As a result, concrete with the following characteristics was obtained: 1550 kg/m3 density, with compressive strength of approximately 21 MPa, having high thermal resistance and maximum permissible application temperature of 1450° c.

Published: June 2017

The main objective of the study was to obtain bio-composites from grey alder sawdust using a mixture of birch outer bark suberinic acids as a binder, and to test their mechanical properties. Ethanol-extracted birch outer bark was used as a raw material for the investigation. Characteristics (suberinic acids content, epoxy acids content and acid number) of the hydrolytically depolymerized birch outer bark binder were also determined. The initial filler/binder ratio and molding parameters (temperature and pressure) were established by the full factorial design. Preliminary data showed that the increase of the pressing temperature from 160 to 200 °C at a pressure of 3.5 MPa resulted in a minor growth of the boards’ density (up to 1.0 g/cm3) and bending strength (up to 17.1 MPa).

Our investigation has shown that it is possible to use one of the plywood production residues – outer birch bark – as a raw material for obtaining particleboards, which have mechanical properties beyond the standard limits. The used method is also environmentally friendly, easy realizable in practice and has a potential to be cost-effective.

The goal of this work is research and development of light sources suitable for use in hospitals, nursing homes, hospices and other similar institutions. During the day spectral power distribution (SPD) of this type luminaire needs to simulate natural day light that affects the natural circadian rhythm of humans. Maintaining the natural circadian rhythm impacts positive on human health, improves mood, prevents the development of depression and helps to overcome them. In the late afternoon increase light in the red-orange part. Light of this kind of spectral composition doesn’t inhibit melatonin production and the human body naturally prepares for rest and sleep. At night artificial lighting should be in the red - orange area to enable patients to sleep and staff to fulfill their obligations. Theoretical analysis and selection of suitable LEDs for the realization of the luminaire with the desired characteristics are made. Performed experimental studies make possible achieving the desired characteristics of light and appropriate LEDs’ modes of operation.
EXPERIENCE OF APPLICATION HIGH PERFORMANCE CEMENT COMPOSITES FOR CREATING DURABLE SCULPTURAL ELEMENTS
Authors: Sahmenko Genadijs , Aispurs Sandis , Korjakins Aleksandrs
Published: June 2017

Traditionally, sculptural and decorative elements of building facades are created from mortar mixes based on lime, gypsum or Portland cement. Generally these materials have porous and permeable structure, which determines their accelerated degradation, especially in the aggressive environment of modern cities. High performance cement composites (HPCC) have been considered for production and restoration of sculptural elements in historical buildings. For this purpose, fine-graded, multi-component and highly workable mixes were elaborated. Mix compositions were modified with micro-fillers, plasticizing and stabilizing admixtures, as well as fibers to improve material ductility and control shrinkage cracking. Basic mechanical properties and durability (such as water absorption, frost resistance) were determined and two types of HPCC were compared (>50 MPa: HPCC and >120 MPa: UHPCC). It has been confirmed that cement composite mixes are characterized by self-consolidating effect, high compressive strength, extremely high resistance versus freezing and thawing cycles and low water absorption. Surface quality was evaluated and initial water absorption (tube tests) were performed for laboratory samples and real sculptural elements after 5 years of exploitation. The results confirmed good potential for using HPCC for creating more attractive and durable architectural shapes and façade elements compared to elements made using traditional cement and lime mortar.

Published: June 2017

In this work changes of electrical and mechanical properties (hardness) of the solid sapropel after its heat treatment were researched. Changes of real and imaginary parts of dielectric permittivity, dielectric losses and specific electrical resistance depending on electrical field frequency in the range 0.01Hz- 1MHz were observed. Temperature dependences of AC (at 1 kHz) and DC electrical conductivity were studied. Chemical sample composition, IR spectra and structure of the solid sapropel were investigated. Heat treatment has a noticeable effect on the electrical characteristics of solid sapropel due to the strong influence of water on the charge transfer in this complex material. Charge transfer occurs predominantly due to ion migration and demonstrates strong dependence upon hydration - dehydration processes. After the heat treatment of the solid sapropel at the temperature of 1000C its hardness doesn’t change. If the sample of the solid sapropel is subjected to 20 min heat treatment at the temperature of 1500C, its hardness decreases by 5.4%, the number of C=C bonds decreases by 6.3±0.1%, the number of C=N bonds decreases by 2.2±0.1%, the number of C-C bonds decreases by 1,7±0.1%, the number of C-H bonds increases by 18.5±0.3%. It shows that in the temperature range 100-1500C destructive processes of the solid sapropel start, although visually (with optical microscope and with SEM) changes of structure are impossible to observe yet.

Bilateral pathological hip dislocation in children
Authors: Garkavenko Yuriy E.
Published: June 2017

Introduction. Pathological dislocation of the hip is one of the most severe complications of acute hematogenous osteomyelitis. The program of treatment for children with pathological hip dislocation is complex, but it has been sufficiently developed and implemented very successfully. At the same time, the available literature provides no cases of treating children with bilateral pathological hip dislocations after hematogenous osteomyelitis. There is no information on the incidence of such cases or in regards to remote functional results.

Materials and methods. The results of the treatment of 18 children with bilateral pathological dislocation of the hip after hematogenous osteomyelitis are presented, which constituted 23.1% of the total number of patients (78) who underwent surgery in 2000–2016 for the diagnosis of pathological hip dislocation. Both hip joints were surgically operated on in 12 patients, while one hip joint was operated on in 6 patients. To assess the anatomical and functional state of hip joints, the clinical and roentgenological diagnostic techniques were used.

Results and discussion. To stabilize and restore the function of the hip joints, 18 children underwent 30 surgical interventions: simple open hip reduction (19) and open hip reduction with hip arthroplasty with one (6) or two (5) demineralized osteochondral allogeneic grafts. The decision regarding the possibility of performing surgical intervention on the second hip joint was made only after a child's check-up examination was complete and after positive information about the anatomical and functional state of the operated hip joint was obtained. According to these criteria, 14 (77.8%) children underwent surgical treatment of the second hip joint 1–1.5 years after the course of conservative measures to restore the range of motion in the previously operated hip joint.

Over a period of 1–12 years, 17 patients were examined, 10 of which underwent an operation on both sides (27 joints). The preservation of up to 80º or more of motion amplitude was noted in 17 (62.9%) of 27 operated hip joints. When assisting patients with pathological hip dislocation, it is necessary to understand that it is practically impossible to restore the affected joint to the anatomical state of the opposite unaffected joint. As for the bilateral lesion, this is most certainly impossible, and the development of arthrosis is inevitable. Therefore, the most important factor reflecting the degree of well-being and stability of the affected joint is the amplitude of active movements. Preserving this amplitude in the affected joints with a careful and attentive attitude is a fundamental and feasible task.

Authors: Umnov Valery V. , Umnov Dmitry V.
Published: June 2017

Aims. To examine the results of treatment for patients with a non-stable form of equino-plano-valgus foot deformity in cerebral palsy with the use of corrective osteotomy of the calcaneus. To further analyze the errors and complications that occurred in patients treated with this technique.

Materials and methods. From 2006 to 2014, 64 patients (103 feet) aged 3 to 17 years were operated using the described method of calcaneus correcting osteotomy. The equinus contracture was eliminated by transection of the gastrocnemius muscle tendon and extending achilloplastic surgery. The abnormal muscle tone was reduced either by administering the drug Dysport into the gastrocnemius muscle or by selective neurotomy of the tibial nerve.

Results. The analysis revealed that there were good results for 75%, satisfactory results for 18%, and unacceptable results for 7% of patients. The unacceptable results of treatment were due to several technical and tactical errors, which were grouped and analyzed.

Conclusion. The analysis of errors and complications of calcaneus corrective osteotomy for patients with cerebral palsy with a mobile form of talipes equinoplanovalgus will enable their future avoidance and improvement of the treatment quality.

Authors: Afonichev Konstantin A. , Nikitin Maksim S. , Proshchenko Yaroslav N.
Published: June 2017

When performing reconstructive surgery in children suffering from extensive post-burn hypertrophic scars, the main problem is deficiency of donor intact skin.

Aim. This study aimed to determine the possibility of using the expander skin balloon expansion method for obtaining free, large area split-thickness skin autografts.

Materials and methods. A comparative analysis of treatment for 39 children with extensive post-burn hypertrophic scars was performed. In 16 children (experimental group), balloon skin expansion of a donor site for obtaining large area split-thickness skin grafts (more than 100 cm²) was performed. In 23 children (control group), the large area grafts were cut off without prior balloon skin expansion of the donor site.

Results. In cases where it is necessary to close a wound defect over 100 cm², it is advisable to perform prior balloon skin expansion of the donor site. This technique enables attainment of an injury-resistant free implant full grafting material and also provides multiple uses of a donor site without disturbing the esthetics.

Authors: Timofeev Igor V. , Dyakonova Elena Yu. , Gusev Aleksei A. , Romanova Ekaterina A. , Khrolenko Polina V.
Published: June 2017

Introduction. The frequency of patellar fractures is approximately 0.5% to 1.5% of all skeletal injuries. The following types of fractures can be distinguished: avulsive, transverse, longitudinal, and comminuted. In cases of displacement of more than 2–3 mm and quadriceps tendon injuries open reduction and internal fixation with the restoration of the articular surface is more preferable. In cases of longitudinal fractures, arthroscopy is regarded as a highly effective method of surgical treatment.

Materials and methods. Using arthroscopy, we have operated on 4 patients with longitudinal fracture of the patella. The average age of the injured persons was 15.4 years (14–17). These were 3 males and 1 female. All patients had sport-related injuries.

Because of the longitudinal fracture of the patella, the lateral knee extensor mechanism remained intact, and arthrosopy-assisted surgical intervention with closed reposition of fragments and transcutaneous wire fixation was performed without wire suturing.

Results and discussion. Minimal invasiveness, the possibility of visual control over the recovery quality of patellar surface, the reliability of fragment fixation, and a significant reduction in the subsequent rehabilitation make arthroscopy a highly effective method of surgical treatment for patellar fractures.

Authors:   Department of Maritime Management Technology, Federal University of Technology, Owerri, Imo State, Nigeria, Nwokedi Theophilus C , Okoroji L. I. , Ikeogu Christopher
Published: June 2017

The aim of the research is to establish the quantitative relationship and impacts of risks associated with various categories of occupational and workplace hazards in the Nigerian seaports. It was carried out by obtaining time series statistical data of 7 years from hazard identification and risk assessment report of Nigerian Ports Authority (NPA) Apapa, western port headquarters. The variables considered are the associated risks of various types of occupational and workplace hazards to which seaport workers were exposed from 2009-2014. The overall level of associated risks of occupational and workplace hazards represent the cumulative of various hazards and were treated as the dependent variable ‘Y’. The exposures to the risks of mechanical hazards, ergonomic hazards, physical hazards, noise/environmental hazards were symbolized as X1, X2, X3, and X4 respectively and treated as independent variables. The method of multiple regression analysis was used to analyze the time series data. T-test was used to test the hypotheses. It was found that risks associated to mechanical hazard, ergonomic hazards, noise/vibration hazard, physical hazards, all have significant impact on the overall level of risk of exposure to occupational and workplace hazards in Nigerian seaport environment. It was recommended that proactive investment in safety inspective and management system is needed to limit the level of exposure of seaport staff to occupational hazards.

Published: June 2017

This paper examines to which extent some maritime business organizations intelligently use their Information and Communication Technology (ICT) resources. The research is done as a pilot study, since it includes relatively small number of maritime business entities from Montenegro, Albania, Croatia, Slovenia and Italy. Our intention was to indirectly check whether these organizations are ready for the adoption and routinization of novel ICT systems like e-Navigation, Maritime Cloud, e-Maritime, National/Maritime Single Window (N/MSW) etc., through assessing how intelligently they exploit existing ICT solutions. Even though all interviewed managers have evaluated knowledge, organizational culture and managerial skills as key constructs that provide the business organizations’ success, the level of intelligent exploitation of the available ICT solutions is not high. This is problematic, especially if we bare in mind the necessity of making quick adaptation to the considerably more complex, sophisticated and demanding ICT solutions within the context of actual huge digital turbulence in the maritime community.

Based on the development of naval ship concept design model history, the three features of development process are further summarized. The first is that model-based system engineering (MBSE) becomes the basic of naval ship concept design, while the second one is that the multi-discipline crossing and combination becomes a general innovation model. And the third one is that systematization oriented naval system integration is the developing goal. Some detailed examples are presented to illustrate these three characteristics. Finally, the technology difficulties in naval ship concept design are also presented.
The Analysis of the Seafares´Employment Legislation in the Republic of Slovenia
Authors:   Ministry of Transport, Slovenian Maritime Administration Koper, Slovenia, Prelaz Lorna , Švetak Jelenko
Published: June 2017

The paper is analysing national and international legislation regarding the seafarer employment. Particular emphasis shall be placed on the fact, that there is insufficient legislation dealing with seafarer labour law in the Republic of Slovenia. On one hand we have the Employment Relationships Act under which the employment contract is concluded between employee and employer. This act determines additional commitments for the employer, which has to submit the contract with seafarer to the evaluation and to the registration. On the other hand there is a Maritime Code under which the employment contract is concluded between the seafarer and ship owner or other person acting on his behalf. Taking into account the national legislation we have to bear in mind the international legislation and especially consider the requirements arising from rules and standards agreed within the International Labour Organization.A comprehensive analysis of this issue presents solutions that the legislator could take into account when preparing employment of seafarer provisions, which need to be systematically, fairly, socially and legally oriented. There is no shipowner included in the maritime training process and consequently there is no system in place for the systematic employment of seafarers. The main goal of this analysis is to find out where the weaknesses are and what should be done better when implementing the Maritime Labour Convention.

Published: June 2017

The in vitro antibacterial and interaction of pure caffeine powder with first line antibiotic against bacterial isolates was investigated by macrobroth dilution and the checkerboard assay methods. This study showed that caffeine and the antibiotics exhibited varied degree of antibacterial activities. While caffeine had MICs ranging between 67.19 and 268.75 µg/ml, chloramphenicol had MICs of between 0.98 and 31.25 µg/ml, kanamycin (15.63 – 62.5 µg/ml), nalidixic acid (0.49 – 250 µg/ml), erythromycin (0.49 – 62.5 µg/ml), tetracycline (1.99 to 62.5 µg/ml) and metronidazole (15.63 to 31.25 µg/ml). Combining ½ MICs and MICs of caffeine with the antibiotics as well as direct combination of caffeine and the antibiotics resulted in significant reduction of the effectiveness of the antibiotics. The fractional inhibitory concentration index (FICI) of the combination of ½ MICs of caffeine with the different antibiotics showed antagonistic interactions with the antibiotics except kanamycin having additive and indifferent interactions with caffeine. The (FICI) of the MICs of caffeine combined with antibiotics showed a reduction in the number of antagonistic interactions as chloramphenicol, nalidixic acid and erythromycin showed some indifferent interactions while kanamycin showed indifferent interaction alone. The direct combination of caffeine and the antibiotics resulted in significant antagonistic interactions higher than when caffeine, at the ½ MICs and MICs, was combined with the antibiotics. Although caffeine demonstrated significant antibacterial activity against the selected bacterial isolates, its combination with the selected antibiotics resulted in significant antagonistic interactions. Caffeine should not be combined with antibiotics as this could result in serious therapeutic failure and, possibly, drug toxicity in vivo.

In a group of girls with epilepsy, apart from low Fe concentration, a high levels of Ca, Mg, Zn, and Cu was noted.In girls with Down's syndrome a high or normal level of Ca, Mg, Zn and Cu was found, whereas Fe concentration presented itself in a non-characteristic way.Both boys and girls, in the group of children with cerebral palsy had  low Fe concentration, as well as low Cu levels was found in older patients. In this group we also noted high concentrations of Ca, Mg and Zn in girls and normal in boys.A high concentration of Ca in girls with cerebral palsy requires separate analysis.Obtained results could be useful as a guidance in the direction and determination of the amount of possible supplementation.
E2F site in the essential promoter region does not confer S phase-specific transcription of the ABCC10 gene in human prostate cancer cells
Authors: Dabrowska Magdalena , Sirotnak Francis M.
Published: June 2017

ABCC10 (MRP7) plays a role in cellular detoxification and resistance to anticancer drugs. Since ABCC10 gene transcription in human prostate cancer CWR22Rv1 cells was found dependent on E2F binding sequence motif, ABCC10 expression in G1 and S phases of the cell cycle of CWR22Rv1 cells, was analyzed. The cells were synchronized in G1 phase by double thymidine block and in S phase by thymidine/mimosine double block. ABCC10 mRNA level was found to be similar in S phase-synchronized and asynchronous cell populations. In G1 phase it decreased by 2.4- to 3-fold. It is thus inferred, that ABCC10 expression in CWR22Rv1 cells is not S phase-specific but is primarily associated with cell proliferation.

O presente artigo aborda a relação entre direito e poder em sua articulação com a política e a violência.  Há no trabalho a pretensão de demonstrar que tal relação revela uma zona de indeterminação entre os meandros do direito e da política. Com isso, pretende-se apresentar as bases introdutórias de uma teoria política do direito, que contribua de maneira enfática e crítica na discussão dos atuais problemas jurídicos, em especial, das características situações que evidenciam um uso do direito enquanto força manipuladora de governabilidade que ocasiona desorientação da própria vida e revela uma dimensão em que o direito e as instituições que dele se utilizam voltam-se contra si mesmas, gerando uma profunda banalização das noções de legalidade e legitimidade em um contexto de crise autoimunitária.
Judicialização, Reserva do Possível e Compliance na Área da Saúde
Authors: Sarlet Ingo Wolgang , Saavedra Giovani Agostini
Published: June 2017

A saúde tem, há muito, enfrentando vários desafios. Em especial, algumas distorções provocadas por excessos da assim chamada “judicialização” da saúde têm gerado muito debate. Se não é possível desconsiderar a relevância da atuação do Poder Judiciário, reflexo das patologias verificadas no próprio sistema público e privado de saúde, também é verdade que a intervenção judicial desmedida se revela preocupante. No presente artigo, pretende-se avaliar esse fenômeno a partir de dois aspectos: o da reserva do possível, como possível limitador do controle jurisdicional, e o do Compliance, como medida preventiva de distorções geradas por eventuais excessos dessa judicialização.
Retórica realista e decisão jurídica
Authors: Adeodato João Maurício
Published: June 2017

O texto objetiva expor as bases de uma retórica realista, sob a perspectiva descritiva de como a decisão jurídica efetivamente ocorre, sem considerações normativas. O idealismo retórico de Aristóteles e seu prestígio posterior reduziram a retórica à arte da persuasão, eliminando elementos importantes da sofística, sobretudo no que concerne à decisão jurídica. Conclui-se com uma perspectiva retórica do ativismo judicial na sociedade complexa.

Background: Inappropriate use of antibiotics for viral upper respiratory infections (URI) directly contributes to antibiotic resistance. Educational interventions reduce antibiotic prescriptions written for viral (URI) symptoms and antibiotic resistance. Objective: This study aims to ascertain whether provider education will reduce antibiotic prescriptions. The study also aims to change provider prescribing practices through education on antibiotic resistance. Methods: Simple random sampling was used to review charts of patients pre- and postintervention in a single provider primary care practice for patients aged 18–64 years with URI diagnosis and/or symptoms. Results: Preintervention, 85% received an antibiotic for URI symptoms compared to 79% in the postintervention group (p = .514). Chi-square analysis comparing the 2 groups indicated there was no statistical significance between the proportion of antibiotics prescribed within these timeframes (p = .58). Conclusion: Morbidity and mortality will continue to increase without aggressive antibiotic stewardship. Although the results did not reach statistical significance, there was still a 6% reduction in the amount of antibiotics prescribed by the single provider. The decrease, albeit small, has the potential for clinical significance, and further studies should be pursued.

Authors: Kuebler Kim
Published: June 2017

The doctor of nursing practice (DNP) provides a link between health policy and practice. This article provides an overview of the current legislation influencing the care and management of the nation’s largest, fastest growing, and costliest patient population—those with multiple chronic conditions. The DNP who remains informed and knowledgeable about the legislative changes directing practice and reimbursement will be prepared to demonstrate quality and value in an era of transparency. A brief overview of merit incentive reimbursement and alternative payment models are described as the United States moves toward population-based health.
Does a Doctor of Nursing Practice Degree Provide Preparation for Assuming a Magnet Program Director Role?

One of the blueprints used by health care organizations for attaining and sustaining nursing excellence is the American Nurses’ Credentialing Center’s (ANCC) Magnet designation. The ANCC requires organizations to identify a Magnet program director (MPD), who serves as the contact and communication point through the process of application, designation, and maintenance of the credential. The MPD role is complex, has a wide variety of necessary skills and competencies, and can be challenging and overwhelming to undertake. Literature reveals no guidelines nor recommendations regarding educational preparation for assuming the role. Chief nursing officers (CNOs) support “program director” as a potential employment option for doctor of nursing practice (DNP) graduates. Given the complexity of the MPD, would DNP education provide elements that would help new MPDs prepare for the position? The purpose of this project was to determine if MPDs recommend concepts within DNP program Essentials as preparation for their roles. A mixed methods design was used, with qualitative data obtained from a focus group and quantitative, nonexperimental data obtained through a cross-sectional survey. Data were collected from current MPDs. The concepts of DNP Essentials presented in the survey were all recommended as preparation for the MPD role, making DNP education a relevant option.
Educational Program to Improve Provider Knowledge, Attitudes, and Behavior in Lesbian, Gay, Bisexual, and Transgender Self-Disclosure
Authors: Henry Amber
Published: June 2017

Lesbian, gay, bisexual, and transgender (LGBT) individuals have long been subject to discrimination. This has led to the fear of victimization and the overall avoidance of health care services and increasing health disparities in this group. Health care providers, including nurses who have limited knowledge, poor attitudes, and behavior, have been shown to significantly dilute the patient–provider relationship. This reduces self-disclosure and increases likelihood of poor outcomes of the LGBT individual. An educational program was developed to focus on health care providers (n = 8) knowledge, attitudes, and behavior in LGBT self-disclosure. A pretest, posttest methodology was used to assess the aforementioned concepts using a 29-item sexual orientation counselor competency scale. All measured concepts showed clinical significance with highest being self disclosure, which revealed both clinical and statistical significance from (SD) 1.0 to 1.63, a 63% increase. The implications of these findings on the current and future practice of health care providers and nurses support cultural competency training for both practicing health care professionals and students in educational curriculums.
Provider Adherence to Evidence-Based Asthma Guidelines in a Community Health Center
Authors: Penkalski Melissa R. , Kenneally Maria
Published: June 2017

Background:Improved outcomes for patients with asthma have been proven with the use of the Expert Panel Report 3 (EPR-3) evidence-based asthma guidelines. These clinical guidelines are tools developed for providers to direct appropriate high-quality patient care that leads to positive outcomes. However, research has shown health care providers do not routinely follow the evidence-based asthma guidelines adequately.Objective:To develop and implement an evidence-based asthma protocol in a community clinic and improve provider adherence and attitudes/beliefs to the EPR-3 guidelines resulting in improved asthma outcomes, asthma control, and self-management for patients with asthma.Methods:The study was conducted in 2 parts over a period of 3 months. First, all medical providers at a community clinic were invited to participate in the research study. The intervention included implementing the asthma protocol within the current electronic health record (EHR). A pre- and postintervention questionnaire measuring provider’s adherence and attitudes to evidence-based practice was administered. In addition, pre- and postclinic aggregate data for International Classification of Diseases codes specific to asthma that correlate to 7 identified aims based on the EPR-3 guidelines were collected.Results:Results show statistical significance among the provider attitudes/beliefs with the intervention, the greatest effect being found for the medical doctors. Four of the 7 aims showed improvement.Conclusions:The findings of this application research quality improvement study indicate that providing necessary tools and resources needed to adhere to evidence-based asthma guidelines can positively affect providers’ adherence and attitudes/beliefs toward evidence-based guidelines.
Establishing a Collaboration Contract to Facilitate Team Performance

Published: June 2017

Effective collaboration is essential for team projects whether related to research, evidence-based practice, or quality improvement efforts and is especially relevant to the doctor of nursing practice (DNP)-prepared nurse (American Association of Colleges of Nursing [AACN], 2006). High-quality projects are accomplished through planning and organization and cannot be left to chance (Yonge, Skillen, & Henderson, 1996). A collaboration contract negates the “left to chance” philosophy by promoting clarity of roles, responsibilities, and team processes. Seven “Cs” of collaboration (contribution, communication, commitment, compatibility, consensus, credit, and cohesion) provide a guiding format for essential components of a contract (Govoni & Pierce, 1997; Lancaster, 1985). This article describes these components and the process for establishing a collaboration contract. An example of a contract is provided that can serve as a template for team projects. Approaches to adapting the contract for use with teams of varied composition are shared. A collaborative contract, along with professional conduct standards, supports achievement of the team goal.
