Published: July 2018

Background:
Radial osteotomy has shown favorable clinical results for early to advanced stages of Kienböck disease. However, it is not clear whether this technique could change the natural course of the disease, or whether its clinical results are actually superior to those of nonoperative treatment. The purpose of this study was to compare radial osteotomy with nonoperative treatment in terms of long-term radiographic and clinical outcomes in patients with Kienböck disease.

Methods:
We systematically reviewed retrospective studies of radial osteotomy and nonoperative treatment for Kienböck disease with long-term follow-up (mean of ≥10 years). A systematic search was conducted across 3 databases (CENTRAL, PubMed, and Embase) and relevant articles were selected. Data regarding patient demographics, treatment details, and radiographic and clinical outcomes were abstracted from the selected studies.

Results:
Seventeen studies (5 of nonoperative treatment and 12 of radial osteotomy) were included. Before treatment, the mean age of patients and mean proportion of wrists with Lichtman stage III or higher were not significantly different between the 2 groups. Neither the mean proportion of wrists that showed worsening of the Lichtman stage after treatment nor the proportion that showed no change in the stage were significantly different between the 2 groups. However, the mean proportion of wrists that had more than moderate pain at the time of final follow-up was significantly lower in the radial osteotomy group (5.7%; range, 0% to 18.2%) than in the nonoperative treatment group (23.2%; range, 17.4% to 35.3%). In addition, the total arc of wrist motion at the time of final follow-up was significantly greater in the radial osteotomy group (107.4° ± 10.0°; range, 93.0° to 126.0°) than in the nonoperative treatment group (88.8° ± 13.2°; range, 68.5° to 103.5°).

Conclusions:
Systematic review of long-term follow-up studies showed that radial osteotomy was not superior to nonoperative treatment in terms of disease progression according to the Lichtman stage. Nevertheless, radial osteotomy was reported to have better outcomes with respect to the extent of pain and range of wrist motion.

A Prospective Evaluation of Patient-Reported Opioid Utilization After Nonoperative Treatment of Fractures and Dislocations
Authors: Zhu Hongyi , Gao Yanchun , Zhang Changqing , Zheng Xianyou 
Published: July 2018

Background:
Prescription of opioid analgesics is currently a common practice to relieve pain for musculoskeletal injuries in many regions of the world, especially in the United States and Canada. However, overprescription may underlie opioid misuse. Details on the utilization of prescribed opioids after nonoperative treatment of fractures and dislocations and whether consumption is related to injury location are unknown.

Methods:
A total of 1,513 consecutive patients in China who underwent nonoperative treatment of a fracture and/or dislocation and who were prescribed opioids were studied over a 3-month period. Demographic information, alcohol consumption, smoking status, injury location, volume of prescription, and consumption patterns were recorded and were summarized.

Results:
The mean number of opioid pills prescribed was 14.7, and the mean patient-reported number of pills consumed was 7.2. Overall, 152 patients (10.0%) reported taking no prescribed opioid analgesics, and 924 patients (61.1%) ceased their prescribed opioids prior to completing the regimen. Injury location, alcohol consumption, and type of fracture or dislocation were all significantly associated with the patient-reported number of opioid pills consumed (p < 0.05). Patients with fracture and/or dislocation of the wrist or forearm (9.4 pills for 3.8 days); ankle, tibia, or fibula (9.3 pills for 3.7 days); or elbow or humerus (9.1 pills for 3.7 days) used more opioid pills compared with patients with injuries at other locations (not exceeding 6.4 pills and 3 days). When compared with patients who had no, low, or moderate daily alcohol consumption, there was more opioid use in patients with high daily alcohol consumption (8.5 pills for 3.4 days) and those with very high daily alcohol consumption (11.3 pills for 4.7 days). Patients with a dislocation and/or displaced fracture reported consuming 8.2 pills for 3.3 days, which was more than the consumption in patients with a nondisplaced fracture (6.2 pills for 2.5 days) and patients with an avulsion fracture (6.2 pills for 2.5 days).

Conclusions:
Surgeons and patients should try to avoid opioids if possible after nonoperatively treated fractures and dislocations. If opioids are used, surgeons should prescribe the smallest dose for the shortest time after considering the injury location and type of fracture or dislocation.

Updating the Coupling Algorithm between HYDRUS and MODFLOW in the HYDRUS Package for MODFLOW
Authors: Beegum Sahila , Šimůnek Jiří , Szymkiewicz Adam , Sudheer K.P. , Nambi Indumathi M. 
Published: July 2018

Core Ideas
The coupling algorithm between HYDRUS‐1D and MODFLOW is updated.
Pressure head profiles are updated based on the groundwater table and bottom flux after each time step.
This eliminates sudden variations in inflow and outflow fluxes with groundwater table changes.
The HYDRUS‐based flow package for MODFLOW (the HPM or the HYDRUS package) is an existing unsaturated zone flow package for MODFLOW. In MODFLOW with the HPM, the groundwater modeling domain is discretized into regular grids that can be combined into multiple zones based on similarities in soil hydrology, topographical characteristics, and the depth to the groundwater. Each of these zones is assigned one unsaturated soil profile (the HPM profile). In this model, after every MODFLOW time step, the flux at the bottom of the HPM profile is given as an input recharge flux to MODFLOW. MODFLOW simulates groundwater flow, and the water table depth at the end of the MODFLOW time step is assigned as the bottom boundary condition in the HPM profile. The current coupling algorithm assumes that the groundwater table in the HPM profile remains constant throughout the entire MODFLOW time step. This results in unrealistic sudden inflow and/or outflow fluxes at the bottom of the HPM profile after every time step. The objective of this study was to develop a methodology to eliminate the error in the determination of the recharge flux at the bottom of the HPM profile. This was achieved by updating or modifying the pressure head profile in the HPM profile after every MODFLOW time step. The effectiveness and the applicability of the new coupling algorithm were evaluated using different case studies. The new coupling algorithm is effective in eliminating unrealistic sudden variations in the bottom flux in the HPM profiles.

Published: July 2018

Background and objectives
Withdrawal from maintenance hemodialysis before death has become more common because of high disease and treatment burden. The study objective was to identify patient factors and examine the terminal course associated with hemodialysis withdrawal, and assess patterns of palliative care involvement before death among patients on maintenance hemodialysis.

Design, setting, participants, & measurements
We designed an observational cohort study of adult patients on incident hemodialysis in a midwestern United States tertiary center, from January 2001 to November 2013, with death events through to November 2015. Logistic regression models evaluated associations between patient characteristics and withdrawal status and palliative care service utilization.

Results
Among 1226 patients, 536 died and 262 (49% of 536) withdrew. A random sample (10%; 52 out of 536) review of Death Notification Forms revealed 73% sensitivity for withdrawal. Risk factors for withdrawal before death included older age, white race, palliative care consultation within 6 months, hospitalization within 30 days, cerebrovascular disease, and no coronary artery disease. Most withdrawal decisions were made by patients (60%) or a family member (33%; surrogates). The majority withdrew either because of acute medical complications (51%) or failure to thrive/frailty (22%). After withdrawal, median time to death was 7 days (interquartile range, 4–11). In-hospital deaths were less common in the withdrawal group (34% versus 46% nonwithdrawal, P=0.003). A third (34%; 90 out of 262) of those that withdrew received palliative care services. Palliative care consultation in the withdrawal group was associated with longer hemodialysis duration (odds ratio, 1.19 per year; 95% confidence interval, 1.10 to 1.3; P<0.001), hospitalization within 30 days of death (odds ratio, 5.78; 95% confidence interval, 2.62 to 12.73; P<0.001), and death in hospital (odds ratio, 1.92; 95% confidence interval, 1.13 to 3.27; P=0.02).

Conclusions
In this single-center study, the rate of hemodialysis withdrawals were twice the frequency previously described. Acute medical complications and frailty appeared to be driving factors. However, palliative care services were used in only a minority of patients.

Abstract
Li-Ni ferrite has gained great scientific elicit owing to of its unparalleled properties and applications. The copper doped Li-Ni ferrite has been synthesized by sucrose method. The structure was characterized by X-ray diffraction, which has confirmed the formation of single-phase spinel structure. X-ray diffraction and FTIR data reveals the formation of cubic structure phase. Unit cell parameters vary with copper content; overall variation of the unit cell parameters obeys Vegard’s law. The main absorption bands of spinel ferrite have appeared through IR absorption spectra recorded in the range of 300–700 cm−1. The copper concentration dependence of lattice parameters obeys Vegard’s law. DC electrical resistivity of the prepared samples decreases with increasing in the temperature which shows the semiconducting behaviour of all nano ferrites. The most prominent influence copper doping on the electrical properties of Li-Ni ferrites has been reported.

Published: July 2018

Abstract
The article focuses on compressive axial loading experimental testing and simulations of topologically optimized design and additively manufactured cervical implants. The proposed platform design is based on anatomical and biomechanical requirements for application in the cervical area. Thanks to new ways of production, such as additive manufacturing, and new software possibilities in the field of structural analysis, which use the finite element method and analysis, it is possible to execute topological optimization of an implant in construction solution, which would be impossible to make by conventional methods. The contribution of this work lies in investigation of 3D printed PLA cervical implant usage in surgical intervention and creation of a numerical static loading modelling methodics and subsequent experimental confirmation of the modelling correctness.

Published: July 2018

Abstract
A major worldwide problem, especially from the perspective of preserving biodiversity and ecological stability (ES) of the landscape, is the significant gradual degradation and loss of habitats. In the context of ever-changing global conditions, the preservation of healthy ecosystems and their valuable services as well as the interconnection of patches of existing habitats should be encouraged. In Slovakia, conception of the Territorial System of Ecological Stability (TSES) was developed. Biodiversity conservation can be created by means of an integrated approach to management of the landscape and careful spatial planning respecting TSES. Land Consolidation (LC) projects, of which TSES constitutes a key part, are amongst the real planning and implementation tools in the Slovak Republic. Thus, TSES represents a real tool for implementation of landscape changes in order to strengthen ES and biodiversity of the landscape with regard to the current European trends in biodiversity policy. This article describes a Local Territorial System of Ecological Stability (LTSES) project developed as a part of LCs in the cadastral territory of Hody (Galanta, Slovak Republic). The aim was to create a functional proposal of LTSES with all basic types of proposals to strengthen biodiversity and ES of model territory – proposal for establishing new eco-stabilising elements – groups and strips of non-forest woody vegetation (NFWV), proposal for ecologically optimal land use, proposal for eco-stabilising measures in forest ecosystems and proposal for hydro-ecological measures.

Published: July 2018

Abstract
Construction industry is considered as one of the most important sectors in Egypt. One of the major challenges faced by the industry, however, is the unavailability of suitable performance measurement systems for assessing companies’ performance. Modern performance assessment systems adopt a more universal approach to the measurement of construction company performance as opposed to the traditional project triangle. This paper aims to examine the practice of performance measurement in the Egyptian construction industry. Results show dominant role of in-house developed performance management systems as well as the use of KPIs as a method of performance assessment. The study further reveals that the highest importance is given to measures related to the time of project delivery, quality of works, clients’ satisfaction and profitability. Hence, the traditional project triangle of project’s success is the most prevalent approach to performance evaluation in the construction industry in Egypt. However, a shift towards a more holistic approach to performance assessment in larger companies was observed.

Published: July 2018

Abstract
Strategic development and planning predetermine all the major fields of activities. Marketing activities are the key tool of communication with a company’s customers, suppliers and other stakeholders. Nowadays, short but informative presentation solutions are becoming more attractive and popular. Companies are using more visuals with a short text in their communication channels as well as in building strategies. One of the tools is the one-page strategic plan (OPSP). The research problem of the paper is how to develop a strategy in its compressed version for the organisation that can have a format which is easy-to-understand and communicate. The paper aims to propose the OPSP model for the Aarong company, which should include both the commercial and non-profit activities. As a research method, the case study of Aarong company was chosen, using the secondary data. The proposed OPSP for Aarong company clearly showed the connections of all key elements of a strategic plan. The practical implications of using the OPSP tool in the Aarong company are clearly visible in terms of synthesis of a complicated strategic plan and having an attractive form of the company strategy for the external communication.
A Slaughterhouse Survey for Porcine Circovirus Type 2 in Commercial Pigs in Ibadan, Southwest Nigeria

Published: July 2018

Abstract
Porcine circovirus type 2 (PCV2) is recognized as one of the most important agents of reproductive disorders in gilts and sows worldwide. It is associated with considerable economic losses in the swine industry due to the unthriftiness, and variable morbidity and mortality it causes in pigs. In spite of the devastation caused by this virus to the global pig industry, there is little or no report of its occurrence in Nigeria. Hence, a slaughterhouse based survey was conducted to determine the prevalence of PCV2 infections in pigs in Ibadan, southwest Nigeria. Using a commercial ELISA kit, 364 pig sera collected from a major abattoir were screened for IgG antibodies against PCV2. The overall prevalence of anti-PCV2 antibodies in the pigs was 1.4 % (5/364), with more female pigs (4/237, 1.7 %) being seropositive than males (1/127, 0.8 %). Since there is no routine vaccination against this swine disease in Nigeria, thus the antibodies detected in the pig sera indicated a natural exposure to the virus. The absence of clinical disease in the pigs also suggests the possibility of a carrier status for these animals and shows that they could serve as hosts for the perpetuation of the disease. These findings underscore the need for continuous surveillance for PCV2 among pigs in Nigeria in order to determine its contribution to production losses incurred in the Nigerian swine industry and aid the development of prevention and control strategies against the disease.

Published: July 2018

Abstract
The antifungal activities of 14 selected essential oils (at the concentrations of 0.5 %, 5 %, and 30 %) against the yeast Malassezia pachydermatis (18 isolates and one reference strain) were investigated. The isolates of M. pachydermatis were obtained from swabs of external ear canals of healthy dogs using sterile swabs. The determination of the efficacy was based on a modified disc diffusion method (CLSI M44-A2). The best antifungal efficacy (100 %) was shown by clove, cinnamon and oregano at the concentration of 30 %; less significant efficacy was shown at the concentration of 5 % (38 %, 33 % and 5 %, respectively). Satureja inhibited the growth of Malassezia (efficacy of 16 %) only at the concentration of 30 %. Bergamot, lavender, juniper, cedar, sage, tea-tree, grapefruit, pine, chamomile and yarrow essential oils were not able to form inhibition zones as defined in the methodology used (greater or equal to 15 mm) in all concentrations used. Therefore, according to the interpretation criterion, they were considered ineffective. In all cases, the concentration of 0.5 % was not effective against the growth of Malassezia yeasts.
