In Central Europe, mugwort pollen is a frequent cause of pollen allergy. Poland is one of the countries with the highest airborne concentrations of pollen of this taxon. Due to its high allergenic potential, Artemisia pollen may pose a significant threat to sensitive subjects during summer months. Plants from this genus often grow in urban and suburban areas.
The aim of the study was to compare mugwort pollen seasons and concentrations of airborne pollen of these plants in 12 cities located in different regions of Poland: Bialystok, Bydgoszcz, Cracow, Lublin, Olsztyn, Opole, Piotrkow Trybunalski, Sosnowiec, Szczecin, Warsaw, Wroclaw, and Zielona Gora. The investigations were carried out with the volumetric method using a Hirst-type pollen sampler (Lanzoni or Burkard) operating on a 24-hour basis. The duration of the pollen season was determined with the 98% method. The earliest onset of the mugwort pollen season was noted in Opole (July 12th), and the latest beginning was recorded in Cracow and Sosnowiec (July 23rd). The maximum pollen concentrations were reported on August 7th and 8th in Lublin (177 grains/m3) and Wroclaw (100 grains/m3). In all the cities, peak days were recorded on the first 10 days of August. The maximum pollen concentrations in the other cities were in the range of 18–89 grains/m3. The highest annual pollen sum was recorded in Lublin (1423) and Wroclaw (1050). These values coincided with the highest pollen concentrations determined in these cities.
The annual Artemisia pollen sums in 2020 did not have the highest values in comparison with other years in these cities. The average annual pollen sum in the five-year period of 2001–2005 was estimated at 2065 in Lublin and 1662 in Wroclaw. Therefore, it can be concluded that the risk of mugwort pollen allergy in the pollen season 2020 was lower than in some previous years.
The socio-economic catalysers of COVID-19 pandemic
Authors: Jošić Hrvoje 
Published: January 2021

Abstract
The COVID-19 pandemic was triggered on December 2019 in the city of Wuhan, China, spreading across the world causing global economic crisis and public health emergency. One could ask: what are the socio-economic factors that catalyse the spread of the disease and why are some countries more affected by the COVID-19 pandemic. Therefore, the goal of this paper is to investigate these socio-economic catalysers of the COVID-19 spread. For that purpose, a cross-country regression analysis was conducted at three time points (April 1st, 2020, April 15th 2020 and April 29th, 2020) using OLS, Tobit and PPML estimators. The results of the analysis have shown that countries with higher gross domestic product per capita, population, HDI and HFI indices have been hardely hit with the global COVID-19 pandemic. When some variables were transformed with by dividing it with the population variable, POPDEN and TOUR variables appeared to be significant. The AGE variable was important in the model taking into account total deaths due to the COVID-19 infection. The limitations of the paper are related to data unavailability for some variables in the most recent year. The results obtained from this analysis should be repeated, taking into account other time points and additional COVID-19 socioeconomic catalysers.

Published: January 2021

Abstract

Objective
The aim of this scoping review was to provide evidence for health practitioners to improve patient education practice for chronic pain management.

Methods
A scoping review was guided by Arksey and O'Malley's (2005)1 five-stage framework, investigated contemporary patient education programs (2007–2018) for chronic pain management in education content, formats of delivery, and tools used for evaluation. Content analysis and description were used for the outcome report.

Results
Seven quantitative studies were included. Education content consisted of General information, Cognitive behavior therapy (CBT), Self-management, and Pain neurophysiology (PN). Education delivery formats varied from workbook to workbook, face-to-face, online, when given for a group or individual or in a combined way. In total, 19 tools were reported for the evaluation of the education programs.

Conclusions
There is a variety in the education content and the delivery formats. The majority of programs showed effectiveness in patients’ chronic pain management based on their selected evaluation tools. This review showed that patient education programs can be useful in chronic pain management. The effectiveness of patient education programs focuses on the improved patients’ physical function and quality of life rather than the cessation of pain only.

Published: January 2021

Abstract

Objective
To explore midwives’ views on how they provide healthy eating education to pregnant women after attending a healthy eating education workshop/webinar.

Methods
A qualitative descriptive approach was utilized. Semi-structured interviews were conducted to explore the views and experiences of midwives on providing healthy eating education for pregnant women. A purposive sample of six midwives was interviewed face-to-face, and one was conducted by telephone interview. Data were analyzed through qualitative conventional content analysis.

Results
Midwives described their views and experiences of factors that impacted their role in providing healthy eating education. They identified three categories: perceived role of midwives, health literacy, and model of care.

Conclusions
Knowledge and confidence of midwives improved after attending the workshop/webinar on healthy eating education. Findings suggested that midwives perceived their role as important in providing nutrition education. However, time and resources were highlighted as challenges when providing healthy eating education for pregnant women. The availability of health literacy and model of care were significant factors in enabling midwives to adequately provide this education. Midwives acknowledged a need for further education in areas of vegan diet, cultural food preferences for ethnic minority groups, and regular updates on national healthy eating guidelines.
Time domain characterization of the Cole-Cole dielectric model
Authors: Holm Sverre 
Published: January 2021

Abstract
The Cole-Cole model for a dielectric is a generalization of the Debye relaxation model. The most familiar form is in the frequency domain and this manifests itself in a frequency dependent impedance. Dielectrics may also be characterized in the time domain by means of the current and charge responses to a voltage step, called response and relaxation functions respectively. For the Debye model they are both exponentials while in the Cole-Cole model they are expressed by a generalization of the exponential, the Mittag-Leffler function. Its asymptotes are just as interesting and correspond to the Curie-von Schweidler current response which is known from real-life capacitors and the Kohlrausch stretched exponential charge response.
In vivo and in vitro Activity of 1-aminocyclopropane-1-carboxylic Acid Oxidase in Germinating Seeds of China Aster (Callistephus chinensis Nees)
Authors: Chojnowski Mariusz , Skorupińska Anna 
Published: January 2021

Abstract
The activity of 1-aminocyclopropane-1-carboxylic acid oxidase (ACO; EC 1.4.3.3) in germinating seeds of Callistephus chinensis was studied. For maximum recovery of ACO activity in vitro, the presence of 10% (w/v) insoluble polyvinylpolypyrrolidone (PVPP) and 30% of glycerol in the extraction medium was necessary. The optimum pH for this activity was 7.0. Ethylene production by whole achenes or enzymatic extract increased due to increasing 1-aminocyclopropane-1-carboxylic acid (ACC) concentrations. Saturation level of ACC for in vivo ACO activity was 10−1 M and Vmax was 10.89 nL C2H4·mg protein−1·h−1. For in vitro ACO activity, the saturation level of ACC was 10−3 M and Vmax was 2.299 nL C2H4·mg protein−1·h−1. Both, in vivo and in vitro ACO activities did not follow Michaelis-Menten kinetics. The Hill coefficients (h) were estimated on the basis of non-linear estimation. Their values were 0.63 for in vivo ACO activity and 1.73 for in vitro ACO activity. The experimental data show that ACO from C. chinensis seeds is an oligomeric enzyme with at least two active sites. During seed germination, in vitro ACO activity was detectable after 12 hours of imbibition, while in vivo ACC conversion to ethylene was observed after 24 h, i.e. – after radicle protrusion. The activity of ACO in C. chinensis seeds is associated with germination sensu stricto, and might be a good marker of this process.
Thyroid autoimmunity in adverse fertility and pregnancy outcomes: Timing of assisted reproductive technology in AITD women
Authors: Wang Jia-Wei , Liao Xiao-Xian , Li Tuo 
Published: January 2021

Abstract
Thyroid autoimmunity (TAI) is prevalent in women of live-birthing age and has independently been associated with complications of fertility and pregnancy, in the case of spontaneous conception or after assisted reproductive technology (ART) treatment. However, it remains challenging to identify causation between infertility and TAI, even interventional trials looking at the impact of levothyroxine (LT4) treatment on fertility and pregnancy outcomes due to differences among study results which related to small scales, impropriate study designs, enrollment criteria of infertility cause and titer/hormone concentration measurements. Furthermore, many questions remain unsettled in ART management in AITD infertile women attempt pregnancy. Therefore, further observational and interventional trials are needed more comprehensive multiple-center, double blinded, and randomized.

Published: January 2021

Regulations regarding transaction of telecommunication devices have been clearly regulated. However, the circulation of illegal products is still rife, especially devices that International Mobile Equipment Identity (IMEI) is not officially registered. This can potentially be detrimental to consumers. This research is normative research with the legal research method of literature. The approach used is a statutory approach and a conceptual approach. It can be concluded that the protection that can be done against consumers is preventive protection that is preventive and repressive protection that is done if the consumer has suffered a loss. Preventive preventive legal protection is contained in the provisions of Law No. 8 of 1999 on Consumer Protection and also contained in government efforts through Regulation of the Minister of Communication and Informatics No. 1 of 2020.Repressive legal protection can be resolved through litigation and non-litigation litigation.Violation of product requirements rules may result in businesses being subject to administrative sanctions.
