Usability of Mobile Health Apps for Postoperative Care: Systematic Review
Authors: Patel Ben , Thind Arron 
Published: May 2020

Background
Mobile health (mHealth) apps are increasingly used postoperatively to monitor, educate, and rehabilitate. The usability of mHealth apps is critical to their implementation.

Objective
This systematic review evaluates the (1) methodology of usability analyses, (2) domains of usability being assessed, and (3) results of usability analyses.

Methods
The A Measurement Tool to Assess Systematic Reviews checklist was consulted. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guideline was adhered to. Screening was undertaken by 2 independent reviewers. All included studies were assessed for risk of bias. Domains of usability were compared with the gold-standard mHealth App Usability Questionnaire (MAUQ).

Results
A total of 33 of 720 identified studies were included for data extraction. Of the 5 included randomized controlled trials (RCTs), usability was never the primary end point. Methodology of usability analyses included interview (10/33), self-created questionnaire (18/33), and validated questionnaire (9/33). Of the 3 domains of usability proposed in the MAUQ, satisfaction was assessed in 28 of the 33 studies, system information arrangement was assessed in 11 of the 33 studies, and usefulness was assessed in 18 of the 33 studies. Usability of mHealth apps was above industry average, with median System Usability Scale scores ranging from 76 to 95 out of 100.

Conclusions
Current analyses of mHealth app usability are substandard. RCTs are rare, and validated questionnaires are infrequently consulted. Of the 3 domains of usability, only satisfaction is regularly assessed. There is significant bias throughout the literature, particularly with regards to conflicts of interest. Future studies should adhere to the MAUQ to assess usability and improve the utility of mHealth apps.
Primary Health Care Facility Preparedness for Outpatient Service Provision During the COVID-19 Pandemic in India: Cross-Sectional Study
Authors: Garg Suneela , Basu Saurav , Rustagi Ruchir , Borle Amod 
Published: May 2020

Background
Primary health centers (PHCs) represent the first tier of the Indian health care system, providing a range of essential outpatient services to people living in the rural, suburban, and hard-to-reach areas. Diversion of health care resources for containing the coronavirus disease (COVID-19) pandemic has significantly undermined the accessibility and availability of essential health services. Under these circumstances, the preparedness of PHCs in providing safe patient-centered care and meeting the current health needs of the population while preventing further transmission of the severe acute respiratory syndrome coronavirus 2 infection is crucial.

Objective
The aim of this study was to determine the primary health care facility preparedness toward the provision of safe outpatient services during the COVID-19 pandemic in India.

Methods
We conducted a cross-sectional study among supervisors and managers of primary health care facilities attached to medical colleges and institutions in India. A list of 60 faculties involved in the management and supervision of PHCs affiliated with the community medicine departments of medical colleges and institutes across India was compiled from an accessible private organization member database. We collected the data through a rapid survey from April 24 to 30, 2020, using a Google Forms online digital questionnaire that evaluated preparedness parameters based on self-assessment by the participants. The preparedness domains assessed were infrastructure availability, health worker safety, and patient care.

Results
A total of 51 faculties responded to the survey. Each medical college and institution had on average a total of 2.94 (SD 1.7) PHCs under its jurisdiction. Infrastructural and infection control deficits at the PHC were reported in terms of limited physical space and queuing capacity, lack of separate entry and exit gates (n=25, 49%), inadequate ventilation (n=29, 57%), and negligible airborne infection control measures (n=38, 75.5%). N95 masks were available at 26 (50.9%) sites. Infection prevention and control measures were also suboptimal with inadequate facilities for handwashing and hand hygiene reported in 23.5% (n=12) and 27.4% (n=14) of sites, respectively. The operation of outpatient services, particularly related to maternal and child health, was significantly disrupted (P<.001) during the COVID-19 pandemic.

Conclusions
Existing PHC facilities in India providing outpatient services are constrained in their functioning during the COVID-19 pandemic due to weak infrastructure contributing to suboptimal patient safety and infection control measures. Furthermore, there is a need for effective planning, communication, and coordination between the centralized health policy makers and health managers working at primary health care facilities to ensure overall preparedness during public health emergencies.
Biofeedback – A Promising Non Pharmacological Tool of Stress – Related Disorders
Authors: Slavikova M. , Sekaninova N. , Bona Olexova L. , Visnovcova Z. , Tonhajzerova I. 
Published: May 2020

Abstract
Biofeedback is a therapeutic method of obtaining better awareness of physiological functions based on principles of operant conditioning and learning in general. While patient observes changes in physiological parameters in real-time (e.g. blood pressure, heart rate variability, temperature, electrodermal activity, etc.), he/she learns how to manipulate them at will. By means of this technique, individuals can improve their mental, emotional, and physical health. Clinical biofeedback training becomes popular for treating a variety of medical conditions, manage ment of disease symptoms, and improvement of overall health through training of stress management. There is no center or group to systematically deal with biofeedback methods in Slovakia, except the Slovak Institute of CBT (cognitive-behavioral therapy) that teaches biofeedback as a therapeutic method. However, biofeedback and its opportunities have a relatively long history of exploration and practice, which is the best precondition for positive changes in this area. The review article aims to provide an insight to biofeedback training as a non-pharmacological therapeutic tool in stress management and stress-related diseases and disorders. The article also describes biofeedback modalities and efficacy on various medical conditions.

Published: May 2020

AbstractIntroduction:Safety climate consists of individual dimensions that might be assessed using specific instruments, e.g., the Hospital Survey on Patient Safety Culture (HSOPS). Establishing the safety climate in healthcare facilities leads to improvements in patient safety.Aim:To assess the safety climate at university hospitals in the Slovak Republic from the nurses’ perspective and to determine the relationship between organisational variables and the particular components of the safety climate.Methods:The study has a cross-sectional design. Data were collected using the HSOPS between December 2017 and July 2018. Two university hospitals participated in the study and overall 280 respondents were included. Respondents were recruited through the purposive sampling method. Data were analysed by descriptive and inductive statistics in the statistical programme SPSS 25.0.Results:Results indicate that in the university hospitals there is a low-level of safety climate. The significant relationship was proved between organisational variables such as the experience in the current position, leaving intention, overtime, perception of staff adequacy, unit type, nurse-patient ratio, and the particular components of the safety climate.Conclusion:Our findings may help hospital management to raise the awareness of the safety climate and to gain a sophisticated overview of the particular components of the safety climate. Adding new organisational variables may help to assess the safety climate from multiple perspectives and, thus, identify areas contributing to patient safety.

Published: May 2020

Abstract
Studies on the adsorption of Pb(II) on plantain peels biochar (PPB) was conducted. The carbonized and activated, biochar was characterized using Braunauer-Emmett-Teller (BET) surface area and x-ray diffraction crystallography (XRD). BET analysis of the PPB indicated that the pore size (cc/g) and pore surface area (m2/g) was 8.79 and 16.69 respectively. Result of the XRD evaluated through Debye-Scherrer equation, showed a nanostructure with crystallite size of 14.56 nm. Effects of initial metal ion concentration, pH, and contact time were studied in a batch reaction process. Results showed that the adsorption of lead from aqueous solution increased with an increase in pH and initial concentration. Equilibrium modeling studies suggested that the data fitted mainly to the Langmuir isotherm. Adsorption kinetic data tested using various kinetic models fitted the Weber and Morris intraparticle diffusion model implicating pore diffusion as the main rate limiting step. The sorption studies indicated the potential of plantain peel biochar as an effective, efficient and low cost adsorbent for remediating lead (II) ions contaminated environment.

Published: May 2020

Abstract

Spilanthes acmella Murr., popularised as toothache plant, is a well-known culinary and medicinal plant for different purposes, but its use as an anthelmintic is apparently exclusive to the Mizo people of India and Myanmar. A chloroform extract of Spilanthes acmella Murr. was analysed in a single quadrupole GC-MS system, from which it was found that the major compound was an alkylamide, N-isobutyl-(2E,4Z,8Z,10E)-dodecatetraenamide. A comparative study was performed on the anthelmintic activity of the plant extract and praziquantel (PZQ) against an intestinal cestode, Raillietina echinobothrida. In terms of efficacy, PZQ was more potent, but the plant extract was also effective at all concentrations tested. PZQ caused severe shrinkage and folds of the tegument, constriction of the suckers, dislocation of spines and erosion of microtriches. The plant extract caused shrinkage and folds on the main body but not on the scolex. Damage on the suckers is more pronounced than in PZQ-treated cestodes. The spines were completely removed. The current findings indicate that S. acmella is a good source of compounds with anthelmintic activity.

Published: May 2020

Abstract
Pyrazolone-based derivative metal complexes were reported to have cytotoxicity in some tumor cells. In this study, the antitumor effect of [Cu(PMPP-SAL)(EtOH)] (PMPP-SAL = N-(1-phenyl-3-methyl-4-propenylidene-5-pyrazolone)- salicylidene hydrazide anion) in murine melanoma B16 cells in vitro and in vivo was investigated. The results showed that [Cu(PMPP-SAL)(EtOH)] inhibited the survival of B16 cells in vitro, and the IC
50 value was superior to cisplatin (DDP) (p < 0.001). B16 cell apoptosis was significantly higher in comparison to the control group (DMSO) (p < 0.01), and cell cycle arrest occurred at the G0/G1 phase. When challenged C57 BL/6J mice were treated with [Cu(PMPPSAL)(EtOH)], a smaller volume of B16 solid tumors were reported than the control group (p < 0.01), with lower positive expression indices of CD 34, vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) (p < 0.01). Moreover, the tumor growth was suppressed in mice due to the induction of apoptosis, as detected by the TUNEL assay (p < 0.001). In summary, [Cu(PMPP-SAL)(EtOH)] effectively inhibited the growth of B16 cells in vitro and in vivo due to the induction of apoptosis and the inhibition of intra-tumoral angiogenesis, demonstrating its therapeutic potential in melanoma treatment.

Published: May 2020

Summary
The aim of the research was to diagnose manifestations of functional and structural disorders and consider the effect of intervention on the musculoskeletal system of students of teacher’s program of physical education. A total of 40 students of Faculty of Sports Prešov University in Prešov participated in the research. As part of the experiment we designed a targeted movement program as an intervention and applied it to an experimental group of students. After 5 months of the intervention, the measurements were repeated. In experimental group we noticed that 30 % of men and 20 % of women improved from III. to II. qualitative degree of shortened muscles. The statistically significant difference (p <.05) was confirmed in group of men. From the perspective of intersexual differences, we observed a statistically significant difference among the shortened muscles in the experimental group (p ≤.05). Changes in structural disorders of the spine after the intervention were statistically insignificant. In regards to good spinal health and muscle balance, we assume that targeted movement program can have preventive effect against functional and structural disorders.

Published: May 2020

Summary
The main aim of this research was to compare differences in heart rate values (HR) of soccer players during small-sided games (SSGs) with different number of players. We assumed that the number of “neutral” player or players in small-sided games will significantly affect the intensity of SSGs and in this case the heart rate values of participating players. The experimental group consisted of older junior players from the FC DAC 1904 Dunajská Streda soccer club (n = 9). The heart rate values were evaluated on the basis of collected data, which we obtained using Polar sport testers and special software Polar Team2. In order to find out the statistical significance of the difference in heart rate was used the One-Way ANOVA and the Bonferroni post hoc test. The level of statistical significance we set at 5 %. We found out that with increasing number of “neutral” players’ the intensity of small-sided games gradually decreased. During SSG1 (3 vs. 3), we recorded the highest achieved average heart rate values of the monitored players, in average 171.33 ± 9.39 beats.min-1. This form of the SSGs was the most intense, but not statistically significant. Our recommendation is to employ SSGs in the systematic training process with different number of players, because we can adequately prepare the players for the match load itself. Attention need to be paid for the playing position requirements.
Livestock Manure Composting in Cold Regions: Challenges and Solutions
Authors: Abdellah Yousif Abdelrahman Yousif , Li Chunyan 
Published: May 2020

Abstract
This review investigates the significant challenges of the process of livestock manure composting in cold regions and assesses the critical features related to the quality of the final compost product. Recently, the composting process has grasped more attention because of environmental pollution concerns and seeks for environmentally-sound approaches for managing livestock manure. Despite recent progress in crucial areas like the microbiology of compost, further improvement is needed in composting process monitoring. Therefore, specific obstacles related to livestock manure composting in cold regions, such as the generation and preservation of temperature, and the solution of obstacles such as inoculation of coldadapted microorganisms, and the role of biochar in prolonging the thermophilic stage of composting were reviewed. Also, the challenges were adequately addressed, and promising strategies to improve composting of livestock manure under harsh conditions were proposed. Still, there is a need for more investigation to get a better understanding of the role of microbial inoculants and biochar amendment regarding the start-up of the composting process in cold regions.

Published: May 2020

Abstract
Patient positioning is a crucial step in neurosurgical interventions This is the responsibility of both the neurosurgeon and the anesthesiologist. Patient safety, surgeon’s comfort, choosing an optimal trajectory to the lesion, reducing brain tension by facilitating venous drainage, using gravitation to maintain the lesion exposed and dynamic retraction represent general rules for correct positioning. All bony prominences must be protected by silicone padding. The head can be positioned using a horseshoe headrest or three pin skull clamp, following the general principles: avoiding elevating the head above heart more than 30 degrees, avoiding turning the head to one side more than 30 degrees and maintaining 2 to 3 finger breaths between chin and sternum. Serious complications can occur if the patient is not properly positioned so this is why great care must be paid during this step of the surgical act.

Published: May 2020

Abstract
New materials and filaments dedicated to 3D printing were obtained using the fused deposition modeling method, and the properties of the produced materials were investigated. Polylactide was used as a polymer base for the assays because of the desired properties of the polymer, mainly biodegradability, and the matrix was refilled by the addition of metallic nanofillers, such as bronze, copper, brass, and steel. For the composites obtained, mechanical properties were investigated to determine the dependence of the obtained results on the content and type of filler used and on the method of fabrication of the fittings. It was found that the additives present in the polymer matrix increased the fluidity of the material. The best results were obtained for the compositions with bronze and steel in which the mass flow rate was 72.97 and 79.99 g/10 min, respectively. The filled material that had lower hardness was measured by Rockwell and the impact strength was measured by Charpy. In addition, it was found that injection-molded parts obtained much better mechanical properties than those obtained by 3D printing.

Abstract
The development of software applications and the use of VR (Virtual Reality) techniques allow to improve the company’s financial result. The construction of models of robotic stations with robots using Virtual Robot technology allows to determine the time of the machining process. It allows its optimization through the selection of accelerations, tools, tooling strategies, and so on. Determining the time of a technological operation translates into savings. This allows you to decide on the purposefulness of the investment. In addition, modern software add-ons, for example, Signal Analyzer in RobotStudio, allow you to monitor the electricity consumption of a robotic station. The article presents a solution showing how, based on the construction of digital models and the use of VR, we can conclude about the profitability of the investment.
Quaternions and Cauchy Classical Theory of Elasticity
Authors: Danielewski Marek , Sapa Lucjan 
Published: May 2020

AbstractDeveloped by French mathematician Augustin-Louis Cauchy, the classical theory of elasticity is the starting point to show the value and the physical reality of quaternions. The classical balance equations for the isotropic, elastic crystal, demonstrate the usefulness of quaternions. The family of wave equations and the diffusion equation are a straightforward consequence of the quaternion representation of the Cauchy model of the elastic solid. Using the quaternion algebra, we present the derivation of the quaternion form of the multiple wave equations. The fundamental consequences of all derived equations and relations for physics, chemistry, and future prospects are presented.
Directional fluctuating asymmetry in certain morphological characters as a pollution indicator: Tigris catfish (Silurus triostegus) collected from the Euphrates, Tigris, and Shatt al-Arab Rivers in Iraq

Published: May 2020

Abstract
The relationship between pollution levels in river sediment and fluctuating asymmetry of resident silurid fish species, Silurus triostegus Heckel, was assessed. Eight bilateral body proportions were analyzed in 1,500 fish from eight river locations. Sediment pollution was measured based on the analysis of heavy metals (Cd, Cr, Cu, Ni, Pb and Zn) and organochlorine pesticides (DDT, DDD, DDE, chlordane, dieldrin, and lindane). The mean quotient approach (mERMq) was used to characterize sediment toxicity, which ranged from low to moderate levels for heavy metals and from low to severe for organochlorides. Variation was noted in the measurements of fish body morphometrics among the sampling locations, which suggested responses to local environments. Levels of asymmetry were positively correlated with both organochlorine pesticides and heavy metals across locations. These results suggest that fish asymmetry variations could be useful for estimating stress caused by organic toxicity based on the mERMq approach.

Published: May 2020

Abstract
In the developing countries, cost-effective observation techniques are very important for earthwork estimation, map production, geographic information systems, and hydrographic surveying. One of the most cost-effective techniques is Precise Point Positioning (PPP); it is a Global Navigation Satellite Systems (GNSS) positioning technique to compute precise positions using only a single GNSS receiver. This study aims to evaluate the efficiency of using Global Positioning System (GPS) and GPS/ Globalnaya Navigatsionnaya Sputnikovaya Sistema (GLONASS) post-processed kinematic PPP solution for digital elevation model (DEM) production, which is used in earthwork estimation. For this purpose, a kinematic trajectory has been observed in New Aswan City in an open sky area using dual-frequency GNSS receivers. The results showed that, in case of using GPS/GLONASS PPP solution to estimate volumes, the error in earthwork volume estimation varies between 0.07% and 0.16% according to gridding level. On the other hand, the error in volume estimation from GPS PPP solution varies between 0.40% and 0.99%.
