Primary Care Physicians’ Experience Using Advanced Electronic Medical Record Features to Support Chronic Disease Prevention and Management: Qualitative Study (Preprint)
Authors: Rahal Rana Melissa , Mercer Jay , Kuziemsky Craig , Yaya Sanni
Published: January 2019

BACKGROUND

Chronic diseases are the leading cause of death worldwide. In Canada, more than half of all health care spending is used for managing chronic diseases. Although studies have shown that the use of advanced features of electronic medical record (EMR) systems improves the quality of chronic disease prevention and management (CDPM), a 2012 international survey found that Canadian physicians were the least likely to use 2 or more EMR system functions. Some studies show that maturity vis-à-vis clinicians’ EMR use is an important factor when evaluating the use of advanced features of health information systems. The Clinical Adoption Framework (CAF), a common evaluation framework used to assess the success of EMR adoption, does not incorporate the process of maturing. Nevertheless, the CAF and studies that discuss the barriers to and facilitators of the adoption of EMR systems can be the basis for exploring the use of advanced EMR features.

OBJECTIVE

This study aimed to explore the factors that primary care physicians in Ontario identified as influencing their use of advanced EMR features to support CDPM and to extend the CAF to include primary care physicians’ perceptions of how their use of EMRs for performing clinical tasks has matured.

METHODS

Guided by the CAF, directed content analysis was used to explore the barriers and facilitating factors encountered by primary care physicians when using EMR features. Participants were primary care physicians in Ontario, Canada, who use EMRs. Data were coded using categories from the CAF.

RESULTS

A total of 9 face-to-face interviews were conducted from January 2017 to July 2017. Dimensions from the CAF emerged from the data, and one new dimension was derived: physicians’ perception of their maturity of EMR use. Primary care physicians identified the following key factors that impacted their use of advanced EMR features: performance of EMR features, information quality of EMR features, training and technical support, user satisfaction, provider’s productivity, personal characteristics and roles, cost benefits of EMR features, EMR systems infrastructure, funding, and government leadership.

CONCLUSIONS

The CAF was extended to include physicians’ perceptions of how their use of EMR systems had matured. Most participants agreed that their use of EMR systems for performing clinical tasks had evolved since their adoption of the system and that certain system features facilitated their care for patients with chronic diseases. However, several barriers were identified and should be addressed to further enhance primary care physicians’ use of advanced EMR features to support CDPM.

Published: January 2019

Objective: The combination therapy of ethinylestradiol and testosterone in post-menopausal females has shown improved sexual response and libido. The present studies were designed to develop a suitable matrix-type transdermal drug delivery system (TDDS) of ethinylestradiol and testosterone using the polymer chitosan.Methods: Five formulations (ET1 to ET5) were developed by varying the concentration of polymer and keeping the drug load constant. Physical parameters and drug excipient interaction studies were evaluated in all the formulations. In vitro skin permeation profiles of ethinylestradiol and testosterone from various formulations were simultaneously characterized in a thermostatically controlled modified Franz Diffusion cell using HPLC. Based on the physical parameters and in vitro skin permeation profile formulation ET3 containing 30 mg/ml of chitosan was found to be the best and chosen for further studies. Optimized formulation was subjected to in vivo pharmacokinetic analysis in rats using ELISA.Results: Stability profile of patch formulation ET3 depicted stability up to 3 mo. One week skin irritation evaluation in rats indicated that formulation ET3 was nonirritating. Combination transdermal patch across rat skin showed a maximum release of 92.936 and 95.03 % in 60 h with a flux of 2.088 and 21.398 µg/cm2h for ethinylestradiol and testosterone respectively.Conclusion: The net result of this study is the formulation of a stable, non-irritating transdermal patch of ethinylestradiol and testosterone, with good bioavailability and can be used as Estrogen Replacement Therapy (ERT) in postmenopausal women.

Authors: El-feky Gina S. , Zayed Gamal M.
Published: January 2019

Objective: The objective of this study was to design an effective topical treatment for oral mucositis.Methods: Poly-(DL-lactide-co-glycolide) (PLGA) nanoparticles (NPs) and Poloxamer407 (PLX)/Hydroxy propyl methyl cellulose (HPMC) hydrogel matrix (HG) were used as combined carriers for benzydamine HCL (BNZ). BNZ loaded PLGA nanoparticles were assessed for their particle size, PDI, zeta potential and entrapment efficiency. Scanning electron microscopy, thermosensitivity study, mucoadhesion study, in vitro release and in vivo investigation were used to characterize the combined BZN loaded PLGA NPs HG.Results: Negatively charged NPs with an average diameter of 139±4.92 nm were incorporated into PLX/HPMC HG bases. The gelation temperature of BZN-PLGA-NPs-HGs ranged between 31°C and 36.5°C. When diluted with saliva simulated fluid, BZN-PLGA-NPs-HGs preserved their gelation properties. Mucoadhesion was found lower for formulations prepared with PLX without HPMC. An increase in the concentrations of PLX from 10 to 30% resulted in an increase in adhesion. Both PLGA-NPs and PLGA-NPs-HG provided a biphasic drug release profile while BZN-HG provided monophasic zero order release pattern. The in vivo study showed that animal groups treated with BZN-HG and BZN-PLGA-NPs-HG showed a significantly higher reduction percentage in ulcer surface area compared to those treated with BZN-PLGA-NPs. BZN-PLGA-NPs-HG group needed 10 d of treatment to complete healing versus 16 d, 14 d and 12 d for the complete healing of groups with no treatment, treated with BZN-PLGA-NPs and treated with BZN-HG, respectively.Conclusion: BZN-PLGA-NPs-HG could represent a promising mean for the effective treatment of oral mucositis induced by cancer therapy.

A SYSTEMATIC REVIEW ON SELF-MICRO EMULSIFYING DRUG DELIVERY SYSTEMS: A POTENTIAL STRATEGY FOR DRUGS WITH POOR ORAL BIOAVAILABILITY
Authors: Radha G V , Sastri K Trideva , Burada Sadhana , Rajkumar Jampala
Published: January 2019

Currently a marked interest in developing lipid-based formulations to deliver lipophilic compounds. Self-emulsifying system has emerged as a dynamic strategy for delivering poorly water-soluble compounds. These systems can embrace a wide variety of oils, surfactants, and co-solvents. An immediate fine emulsion is obtained on exposure to water/gastro-intestinal fluids. The principal interest is to develop a robust formula for biopharmaceutical challenging drug molecules. Starting with a brief classification system, this review signifies diverse mechanisms concerning lipid-based excipients besides their role in influencing bioavailability, furthermore pertaining to their structured formulation aspects. Consecutive steps are vital in developing lipid-based systems for biopharmaceutical challenging actives. Such a crucial structured development is critical for achieving an optimum formula. Hence lipid excipients are initially scrutinized for their solubility and phase behavior, along with biological effects. Blends are screened by means of simple dilution test and are consequently studied with more advanced biopharmaceutical tests. After discerning of the principle formula, diverse technologies are offered to incorporate the fill-mass either in soft/hard gelatin capsules. There is also feasibility to formulated lipid-system as a solid dosage form. Although such solid technologies are desirable but such should not undermine the biopharmaceutical potential of lipid-formulations.

Published: January 2019

The success during the operation of natural gas processing plants depends on the correct estimation of thermodynamic properties of the system. This paper calculates the equilibrium curves of real and synthetic natural gas mixtures means of three Equations of State (EOS). These equilibrium curves were constructed and compared with experimental data found in the literature covered. The results showed that, above 4 MPa the Peng-Robinson equation presented a considerable deviation with respect to the experimental data, reaching an absolute error of 4.36%; therefore, the GERG2008 equation is recommended for systems that operate at high pressures when the components present in the mixture apply.

Authors: Huner Umit
Published: January 2019

The aim of this research paper was to investigate the
synergetic effect of micro cellulose and multi-walled carbon nanotubes (MWCNTs)
combination on physicochemical, mechanical and reprocessing performance of Poly
(Vinyl Alcohol) hybrid composite films. The hybrid composite films production
was carried out by the solution casting method, and the reprocessed films were
produced using defective (torn, faulty) films from primary production by the
same method. The combined use of MWCNTs and micro cellulose improved the
hydrophobicity approximately 85% in ratio. After the reprocessing, decreased
intensities of the peaks in the FTIR and Raman results confirmed the reduced
molecular interaction between all components of the hybrid composite film,
moreover, SEM and TEM revealed the negative defects such as agglomeration which
caused mechanical strength decrease. The tensile strength of PVA hybrid
composite films loaded cellulose/MWCNTs, reached 97 MPa strength value and
elongation at break decreased to 33% according to the neat PVA film. The study
results revealed that hybridization had a remarkable impact on improving
characteristic properties of composite films and reprocessing process might
have been compatible with solution casting method.

A Credit-based Method to Selfish Node Detection in Mobile Ad-hoc Network
Authors: Nobahary Sanaz , Babaie Shahram
Published: January 2019

Ad-hoc networks are a set of mobile nodes that are connected via a wireless channel. Some of the nodes in this network behave selfishly and do not send data to other nodes so that in order to increase network performance these nodes must be identified. A credit-based algorithm is proposed to detect the selfish nodes. Three watchdog nodes are selected to monitor suspicious nodes in each cluster. The cluster head nodes detect the existence of selfish nodes by controlling general features of network, such as delay, the total number of sent packets, the total number of received packets, throughput, and network traffic. The watchdog nodes send their comment on selfishness or cooperation of the node to the cluster head. Cluster head makes decisions with a majority vote on a suspicious node. The simulation results show that the rate of detection accuracy and the life time of network are considerably high and the false alarm rate and energy consumption are low comparing to that of similar methods.

Published: January 2019

The production of traditional meat products has a considerable potential in the Republic of Serbia, particularly in small and micro (household) establishments. Among a large number of traditional meat products, dry fermented sausages and dried meat products are the most important and commonly appreciated by consumers. There is, however, a need for a better standardization of the production in this meat sector, and also implementation of necessary food hygiene rules and HACCP principles according to hygiene regulations. There are provisions in the Food Safety Law, stating the principles of flexibility, which would allow for traditional meat producers and their associations to apply for derogations in food hygiene regulations. This would enable traditional small and micro food business operators to better use their resources, relax administrative burden and use traditional production methods in the most appropriate manner, always respecting hygiene and safety principals. This review paper analyses the current status of traditional meat production in small and micro establishments in Serbia, emphasizing a need for further improvements in food safety management and standardization.

Published: January 2019

Over the past decades, different mycobacteriosis agents have become important fish pathogens. The present study describes a different mycobacteriosis in farmed sea bream (Sparus aurata) caused by Mycobacterium frederiksbergense in Turkey. Affected 15 fish, weighing 15 to 20 g, showed lethargy, stunted growth, pale skin, dorsal fin necrosis, and a significant level of mortality (40 %) in fish stocks. Internally, no multifocal white-colored granulomas in the visceral organs were observed. Inoculation of the visceral organs onto Löwenstein-Jensen medium and Tryptic Soy Agar (1.5% NaCl) slants produced only fast-growing (2-3 weeks), orange to yellow-colored, photochromogenic acid-fast colonies. Ziehl-Nielsen positive bacterial isolates were identified using a commercially available line probe assay (Genotype Mycobacterium CM/AS assay) and with 16S rRNA gene sequencing analysis based on 16S rRNA gene sequencing, fifteen isolates were identified as Mycobacterium frederiksbergense. Histopathologically, epithelioid cell granulomas were not observed in any vicseral organs but acid-fast bacteria were detected in the liver, kidney, spleen, and heart tissue. This study shows that asystemic mycobacteriosis is observed in sea bream with high mortality.

Published: January 2019

Lidia cattle are a heterogeneous Iberian cattle population known for its natural aggressiveness and resistance to traditional handling procedures making in vivo blood sampling and biological fluid collections extremely difficult. Blood variables are influenced by physical exertion and stressful situations; consequently, post-mortem blood analysis does not reflect basal concentrations for this species. Nevertheless, ocular fluids (aqueous and vitreous humour) maintain their stable composition after death and maybe could be used to estimate ante-mortem blood concentrations. So, 15 bulls which had fought (for 15-20 minutes) and, subsequently after death, blood, aqueous and vitreous humour were sampled. Total protein, albumin, triglycerides, uric acid, urea, AST, ALT, GGT, AP, CK, LDH, cholesterol, creatinine, glucose and lactate were measured. Statistical analysis and correlation coefficients between the three fluids were carried out. All variables showed high plasma concentrations of glucose, uric acid, LDH and CK, compared with normal bovine concentrations. Apart from urea, all plasma concentrations were greater than those found in ocular fluids. The measured enzymes activities were higher in the vitreous than in the aqueous humour, but only marked differences in uric acid, lactate, AP and AST were found. There was a significant correlation between creatinine in the plasma and aqueous humour, and between albumin and GGT in the plasma and vitreous humour. Glucose, creatinine and urea exhibit a high correlation between ocular fluids. All plasma concentrations were clearly modified, however ocular fluids do not seem affected, thus establishing important correlations between the blood and intraocular fluids.

Published: January 2019

The aim of this study was to emphasize the importance of conservation of the Lipe sheep, as a local endangered type of Zackel breed, and to perform a comprehensive phenotypic characterization in order to ensure a better use and preservation of this genetic resource. In addition, we compared the results of a detailed morphometric characterization of the modern Lipe sheep carried out in the present study with the morphometric parameters of the native form of this breed described in 1935. The comparative analysis revealed the development dynamics of the local Lipe sheep in the traditional habitat, over a period of nearly one century. Throughout this period, different factors affecting Lipe sheep management, such as biogeografic, agro-economic, sociocultural and others, led to significant population erosion, and to the current status of the Lipe sheep as an endangered genetic resource. Although a slight increase has been registered in some body measurements, the major body indexes of the Lipe sheep, such as body format, body compactness, body massiveness, body proportion, pelvic, and head index, remained without significant fluctuations over the last century (p>0.05). Body length of the modern type still exceeds the height at withers, which was also recorded in the native Lipe sheep nearly 100 years ago. A prominent sexual dimorphism is still evident. Therefore, our comparative analysis showed no significant differences between the native and modern form of Lipe sheep in their body format and growth potential. The slight increases in absolute body measurements of the modern Lipe type we recorded could be linked to better housing conditions and improved quality of feed, without application of strategic selection measures over the last 100 years. The importance of conservation of this ovine resource is less economical, but mostly cultural, historical and heritage oriented, and still essential for the survival of the breed.
Effects of Breed/Species and Gender on Platelet Concentration in Autologous Platelet Rich Plasma
Authors: Miranda Stephania , De Mello Costa Maria Fernanda , Jeunon Senna Juliana , Frapoint João Castañon , De Alencar Nayro Xavier , Barroso Lessa Daniel Augusto
Published: January 2019

Platelet rich plasma (PRP) is an autologous biological product harvested by consecutive centrifugations of whole blood and separation of plasma in a stepwise protocol. PRP has been successfully used to stimulate healing in orthopedic and dermatological conditions, both in humans and animals. The principle is the fact that α- granules inside platelets contain a high concentration of growth factors, that once released can interfere with cellular communication and speed up healing. Standardization of PRP requires establishing a gold standard for the preparation and evaluation of the product, especially considering that platelet concentration and, therefore, growth factor concentration, might vary due to a number of variables. Factors such as age, gender, race or breed, and immune status of the patient might interfere with PRP quality and with treatment results, although little is known about such interferences. This research investigated the effect of breed/species and gender in platelet concentration in autologous PRP from horses and mules. The results demonstrate that Quarter Horses provided PRP with the greatest amount of platelets, although mules had a higher concentration percentages in relation to the initial platelet counts.
Mycorrhiza and Stress Tolerance of Vegetables: A Review
Authors: Adamec Samuel , Andrejiová Alena
Published: January 2019

From year to year, the world growing area is being more poluted with heavy metals or excessive salt level and exposed to lack of moisture or avaiable nutrients in the soil. This resulting in a loss of agricultural land where vegetables were grown in the past. The producers must also fight with more resistant and new species or strains of soil pathogens, while chemical protection is not always the most suitable solution for human health and the environment. Our review focuses on the great importance of using arbuscular mycorrhizal fungi to alleviate abiotic and biotic stress, taking into account the use in vegetable production. The review is gradually focusing on individual stressors and defines the mechanisms of mycorrhizal fungi that contribute to the sustainable agriculture even under severe stress conditions.

Published: January 2019

Objective: The main aim of the study was to explore muscle mass changes and to investigate musculoskeletal inflammation in critically ill patients.

Methods: A pure observational study that comprised two musculoskeletal analyses was conducted. Ultrasonography was used to determine the inflammatory process and muscle mass modifications. We assessed the presence of musculoskeletal inflammation and muscles area reduction. We recruited 26 patients and we performed both imaging investigations (shoulder and hip joints, biceps brachii and rectus femoris areas) and anthropometric measurements (mid-upper arm circumference).

Results: More than 70% of patients were classified with low muscle mass, over one half of sarcopenic patients being over-weight and 17% being obese. The relationship between the length of stay in intensive care unit, mechanical ventilation and presence of low mid-upper arm circumference, highlighted a significant difference when comparing sarcopenic and non-sarcopenic groups. Musculoskeletal inflammation expressed by step-down lesions, calcifications and osteophytes, is common in these patients. Statistically significant results were obtained when comparing the dimensions of the investigated muscles. Good inter-observer variability in day 3 of assessment for biceps brachii and rectus femoris was noticed.

Conclusions: More than 1/3 of critically ill patients included in the present study was classified with low muscle mass. The length of stay in intensive care unit and the length of mechanical ventilation had an important impact on sarcopenic patients. Musculoskeletal impairment was frequent, reflected by presence of enthesitis lesions in joints and by dynamic reduction of muscle area.

and semigroup algebra, l
1(Sr) on restricted semigroup, Sr are investigated for different classes of inverse semi-groups such as Brandt semigroup, and Clifford semigroup. We particularly show the equivalence between pseudo-amenability and character amenability of restricted semigroup algebra on a Clifford semigroup and semigroup algebra on a restricted semigroup. Moreover, we show that when S = M
0(G, I)is a Brandt semigroup, pseudo-amenability of l

In this work, we present a comparative study between four-level neural space vector modulation (4L-NSVM) and three-level neural space vector modulation (3L-NSVM) technique in indirect vector control (IVC) of reactive and active power control of a doubly fed induction generator (DFIG) for wind energy conversion systems (WECSs). Two controls techniques using IVC-4L-NSVM and IVC-3L-NSVM are proposed and compared. The validity of the proposed control schemes is verified by simulation tests of a DFIG-based wind turbine system (WTSs). The stator active power, stator reactive power and rotor current is determined and compared in the above strategies. The obtained results showed that the proposed IVC with 4L-NSVM technique have reactive and stator active power with low powers ripples and low rotor current harmonic distortion than 3L-NSVM technique.

The diet of the greater forkbeard Phycis blennoides (Brünnich, 1768) of the Algerian coast was studied between December 2013 and June 2015, providing information on its ecology for a better understanding of the feeding strategy. A total of 956 individuals, whose total length (TL) varied between 9.7 and 54.5 cm and weight (W) between 2.80 and 1334.11 g, were examined. The index of relative importance (%IRI), combining the three main descriptors of the presence of different ingested prey (%F, %N, %W), was used to characterize the relative importance of different food taxa. Qualitative and quantitative variations in diet were studied according to sex, size and seasons. The average annual digestive vacuity index (%V) was 5.51. It did not vary between seasons (x2
cal = 5.43, x2
th = 7.82, α = 5%) and size (x2
cal = 2.08, x2
th = 5.99, α = 5%), but was different between male (%V = 4.94) and female (%V= 12.78). Qualitative analysis of stomach contents reveals a fairly diverse range of predation with 1342 preys counted for a total weight of 462.84 g, which corresponds to an average number (AN) and weight (AW) of 3.03 and 1.04 g, respectively. This species feeds on benthic preys, composed mainly of natantia crustaceans (%IRI = 44.84) and teleost fish (%IRI = 2.61) with intraspecific preys (%IRI = 6.15). This cannibalism was frequent in specimens with a TL that exceeds 20 cm; it was even more frequent in females as well as in winter. Significant differences in feeding habits of P. blennoides occurred according to sex, fish size and between seasons. The trophic level (TROPH) was high (3.66 < TROPH < 3.97), corresponding to carnivorous character.

Published: January 2019

Sport and recreational marine fishery can significantly contribute to the national budget through its economic and social effects. The main aim of this research is to define the economic and social significance of sport and recreational fishing in Croatia through the assessment of the lower limit of its economic value. This is done by analyzing the segments of sport and recreational fishing together with the economic and other activities which are closely related to it. When expressed by the number of stakeholders involved in sport and recreational fisheries and the share in the gross domestic product, it can be concluded that the economic effects of these activities are only slightly lower than in commercial fisheries. This research provides the groundwork for pointing out the basic guidelines of the social significance of sport and recreational marine fishery in Croatia. Hence, it can be noted that sport and recreational fishing in local coastal communities support the overall development of rural areas and the local communities in particular.
Phototactic Response and Morphometric Characteristic of Climbing Perch Anabas testudineus (Bloch, 1792) Under Culture System
Authors: Ahmadi Ahmadi
Published: January 2019

Phototaxis in climbing perch (Anabas testudineus) was investigated by subjecting fish to LED light traps (blue, green, yellow, orange, red, white) and control (total 13 traps). The trap was constructed of polyamide (PA) nylon monofilament (31.75 mm mesh size), fastened around two wire ring frames (∅ 490 mm) with a net height of 270 mm. A lamp was placed on the bottom of the trap. 96 individuals, consisting of 34 males and 62 females, were analysed. Both continuous and blinking light traps were considerably higher in the number of catch compared to the control. The body size of catch ranged from 76-135 mm TL and 8.00-55.00 g W. The mean YPUEs (yield per unit effort) for male and female were 4.00 ± 2.25 and 7.00 ± 4.50 g trap−1 trial-1, respectively. The CPUEs (catch per unit effort) for continuous, blinking light traps and the control ranged from 0.43 to 0.93, 0.21 to 0.86, and 0.21 fish trap−1night−1, respectively. The mean condition factor (K) values of 2.10 ± 0.40 for males and 2.13 ± 0.34 for females indicate fish with better condition. Positive group responses of fish were more pronounced in the middle size classes between 90 and 109 mm TL. Negative allometric growth pattern (b) (1.7271-1.8828) was observed, indicating that the culture system should be refined. A. testudineus showed positive phototaxis to the “colors of light”. In addition, efforts to collect climbing perch from the wild for breeding and commercial purposes may benefit from this study.
In defense of a pluralistic policy on the determination of death
Authors: Dranseika Vilius , Neiders Ivars
Published: January 2019

In his paper “The challenge of brain death for the sanctity of life ethic”, Peter Singer advocates two options for dealing with death criteria in a way that is compatible with efficient organ transplantation policy. He suggests that we should either (a) redefine death as cortical death or (b) go back to the old cardiopulmonary criterion and scrap the Dead Donor Rule. We welcome Singer’s line of argument but raise some concerns about the practicability of the two alternatives advocated by him. We propose adding a third alternative that also – as the two previous alternatives – preserves and extends the possibility of organ transplantation without using anyone without their consent. Namely, we would like to draw readers’ attention to a proposal by Robert Veatch, formulated 42 years ago in his 1976 book “Death, dying, and the biological revolution” and developed further in his later publications. Veatch argues for a conscience clause for the definition of death that would permit people to pick from a reasonable range of definitional options. This autonomy-based option, we believe, is more likely to be practicable than the two options advocated by Singer. Furthermore, we present data from a study with Lithuanian participants that suggest that there is quite pronounced variation of preferences concerning death determination.
Land Use Changes in Spain. Drivers and Trends in Agricultural Land Use
Authors: Mar Delgado-Serrano María , Ángel Hurtado-Martos José
Published: January 2019

Land is an essential resource and plays a vital role in providing food and food security, water, ecosystem services and territorial resilience. However, the past few decades have generated enormous and increasingly unsustainable pressures on land use. The objective of this research is to analyse the main land use changes in Spain between 1987 and 2011 using data provided by the Corine Land Cover (CLC) project. The general trends in land use change at CLC level 1 in this period, and more specifically the changes occurring at CLC level 3 in land destined for agricultural use are analysed. The main reasons that explain these changes, including policy influences, are then identified. The results show that the area occupied by buildings and infrastructure has doubled, agricultural land has decreased and irrigated land has increased; forested areas have also increased, but their ecological quality has been degraded. These trends question the future sustainability of that land use in the analysed period.
Provision of Public Services in the Light of Current Global Trends
Authors: Bumbalová Monika
Published: January 2019

Provision of services by public sector is a concept, which has been implemented for many decades in various forms of economic arrangement. Public sector policies and public services have significant impact on almost all spheres of life including agriculture. Throughout the history, there were times with smaller and bigger importance of public sector within the economy. The conditions of public sector always depend on the actual trend applied in the sphere of public administration and public management. After the period of New Public Management accompanied by leaning away from the “public” concept, a return to stronger statehood and more intensive public sector can be seen. There are several reasons for such development, which are also called megatrends. Urbanization, demography and social changes, climate changes and development of technology belong to the most intensive ones. The presented review paper deals with the description of the mentioned trends and provides a reflexion on their influence on the public sector and provision of public services in particular.
