Authors: Ishak Pertiwi , Kabo Peter , Yusrini Djabir Yulia 
Published: October 2021

ABSTRACT
Excessive doses of paracetamol have the potential to cause acute kidney injury and even death. Gynura procumbens has been traditionally used as folk-medicine for kidney disease. This study aimed to examine the nephroprotective effect of Gynura procumbens leaf extract against paracetamol-induced nephrotoxicity in rats. Twenty-five male wistar rats (150-200 g) were divided into 5 groups. Healthy control group, placebo group, and 3 extract treatment groups that received either 100 mg/kg, 200 mg/kg or 300 mg/kg dose. The placebo (sodium carboxymethyl cellulose) or extract was given 4 consecutive days prior to paracetamol (2400 mg/kg) administration on day 5. Blood samples were withdrawn before treatment initiated (day 0), after treatment before paracetamol administration (day 5) and 24-hour after paracetamol administration (day 6). Blood samples were analyzed to obtain urea and creatinine levels. In addition, histopathological analysis was performed on the renal tissue. Paracetamol administration was shown to significantly increase the urea and creatinine levels, and the extract at 300 mg/kg dose was able to significantly prevent the elevation of the renal biomarkers. The histopathological analysis also revealed a significant reduction in renal histopathological injury in 300 mg/kg extract group. It can be concluded that the ethanolic extract of the Gynura procumbens at a dose of 300 mg/kg has a good protective effect on kidney function and tissue structure.

OBJECTIVE
Posttransplantation diabetes mellitus (PTDM) effects up to 30% of all kidney transplant recipients (KTR). Recent studies in mice found that sufficient androgen levels are necessary for β-cell health and adequate insulin secretion. This raises the question whether a similar relationship might be present in KTR. Hence, we hypothesized that dihydrotestosterone and testosterone are associated with the development of PTDM in male KTR.

RESEARCH DESIGN AND METHODS
We conducted a post hoc analyses of a prospective single-center cohort study including adult male KTR with a functioning graft ≥1 year posttransplantation. Androgen levels were assessed by liquid chromatography–tandem mass spectrometry. Development of PTDM was defined according to the American Diabetes Association’s criteria.

RESULTS
We included 243 male KTR (aged 51 ± 14 years), with a median dihydrotestosterone 0.9 (0.7–1.3) nmol/L and testosterone of 12.1 (9.4–15.8) nmol/L. During 5.3 (3.7–5.8) years of follow-up, 28 KTR (11.5%) developed PTDM. A clear association was observed, as 15 (19%), 10 (12%), and 3 (4%) male KTR developed PTDM in the respective tertiles of dihydrotestosterone (P = 0.008). In Cox regression analyses, both dihydrotestosterone and testosterone as continuous variables were inversely associated with the risk to development PTDM, independent of glucose and HbA1c (hazard ratio [HR] 0.31 [95% CI 0.16–0.59], P &lt; 0.001; and HR 0.32 [95% CI 0.15–0.68], P = 0.003, respectively).

CONCLUSIONS
Our results suggest that low androgen levels are a novel potential modifiable risk factor for the development of PTDM in male KTR.

Regional eco-efficiency of the agricultural sector in V4 regions, its dynamics in time and decomposition on the technological and pure technical eco-efficiency change
Authors: Richterová Eva , Richter Martin , Sojková Zlata 
Published: October 2021

Research background: Agriculture plays a vital role in producing food to ensure food security, but it is one of the biggest contributors to environmental pollution. One of the main goals of the new CAP is to set higher ambitions for environmental actions, which brings into the front the concept of agricultural eco-efficiency. The notion of eco-efficiency includes the economic and also ecological dimensions of sustainable agriculture.
Purpose of the article: The main goal of this paper is to evaluate the eco-efficiency of agricultural production and its dynamics during the years 2013, 2015, and 2017 of NUTS 2 regions within the Visegrad 4 (V4), i. e. The Czech Republic, Slovakia, Hungary, and Poland. The part of the main goal is to verify the research hypothesis that all the biggest agriculture producers are eco-efficient.
Methods: V4 regional eco-efficiency of the agricultural sector is expressed by the Malmquist productivity index and is estimated using the output-oriented Data envelopment analysis (DEA) model, under the assumption of constant return to scale (CRS). The Malmquist index is decomposed to technical eco-efficiency change (EC) and technological change (TC). Based on the eco-efficiency, technological and pure technical eco-efficiency change, V4 regions are classified into three groups: the most progressive regions, the progressive regions, and the regressive regions.
Findings & value added: CZ02: Central Bohemia, CZ04: Northwest, HU33: Dél-Alföld, HU31: Észak-Magyarország, HU32: Észak-Alföld, PL21: Malopolskie, PL41: Wielkopolskie, SK01: Bratislava region, and SK02: Western Slovakia have an eco-effective agricultural sector, the remaining V4 regions have eco-ineffective agricultural sector. The research hypothesis that all the biggest agricultural producers are eco-effective is not confirmed. During the analyzed years, 19 V4 regions improve their agricultural eco-efficiency. The main contributor to eco-efficiency improvement is technological progress, which indicates that producers implement innovations that lead to more eco-efficiency agricultural production.
Comparative analysis of Poland and selected countries in terms of household financial behaviour during the COVID-19 pandemic
Authors: Waliszewski Krzysztof , Warchlewska Anna 
Published: October 2021

Research background: The outbreak of the COVID-19 pandemic, the reduction in income or the total loss of jobs have affected the financial behaviour of consumers worldwide. Managing the budget in times of turbulence and crisis has posed a challenge for households.
Purpose of the article: The aim of the article is to determine to what extent the COVID-19 pandemic has affected the financial behaviour of the inhabitants of various countries and how Poland has stood out from the rest.
Methods: Due to the orderly nature of the questions analysed, non-parametric tests were used in the analysis. The distribution of current expenditure in comparison with the period before the pandemic was analysed, as well as the results of comparative analyses with Mann-Whitney U tests for comparison of Poland with Austria, Belgium, the Czech Republic, France (974), Germany, Italy, Luxemburg, the Netherlands, Romania, Spain, Turkey, the United Kingdom, the USA. A study was carried out on the relationship between planning for the future, having debts and savings and financial behaviour after the COVID-19 pandemic and the metric variables in the group of Poles via Chi square and a series of ? Kendall?s tests.
Findings & value added: There has been a fall in expenditure compared to the period before the pandemic, which may explain the lack of opportunities to spend money, the fall in revenue and the freezing of expenditure for fear of an uncertain future. There has also been a change in the way payments are made. Payment cards and purchases made over the Internet are increasingly popular. In the face of the COVID-19 pandemic, consumers are trying to save more, but not everyone can afford to do so. Long-term value added of this paper is analysis of change in the model of financial behavior of households under the shock of the pandemic in international comparisons of the analysed countries.
Determinants of board diversity policy implementation by companies listed on the Warsaw Stock Exchange
Authors: Wawryszuk-Misztal Anna 
Published: October 2021

Research background: Diversity management is one of the hot topic issues present in current public discussions. Board diversity requirements are quite new for Polish public companies. The companies listed on the Warsaw Stock Exchange have to publish a statement on the company's compliance with the corporate governance recommendations and principles included in ?Best Practice for GPW Listed Companies 2016?. This regulation is based on the 'comply or explain? principle, thus the company may decide whether to comply with every rule included in the code, but decision on not implementing one or more rules should be explained by the company. Some of the recommended rules regard the board (supervisory and management) diversity policy implementation, where diversity refers to such dimensions as gender, education, age and professional experience.
Purpose of the article: This study aims to investigate determinants of board diversity policy implementation by domestic companies listed on the WSE. It also documents explanations provided by companies that do not apply board diversity policy.
Methods: The research sample covers 268 non-financial domestic companies listed on the Warsaw Stock Exchange between 2016 and 30 November 2018. The companies? current reports on company compliance with the corporate governance codes and information issued on companies? websites were analyzed in order to identify those that announced implementation of board diversity policy. This study uses logistic regression analysis to identify the firm-level characteristics that may influence the implementation of board diversity policy.
Findings & value added: This is the first study analyzing the drivers of board diversity policy implementation by Polish companies listed on the WSE. It shows that large companies, companies with larger management boards and companies with women acting as presidents of the supervisory boards are more likely to take actions seeking to achieve management and supervisory board diversity.

Effect of food toys on owner-perceived quality of life of cats during a prescribed weight loss plan
Authors: Dodd Lauren E. , Werre Stephen R. , Shepherd Megan L. 
Published: October 2021

Abstract

OBJECTIVE
To determine the effect of a food toy on owner-perceived quality of life (QOL) of overweight cats during a weight loss plan.

ANIMALS
44 adult cats, 1 to 10 years of age with a body condition score (BCS) ≥ 7/9.

PROCEDURES
Cats were randomly assigned to the food toy or food bowl group. Cat owners completed an initial questionnaire and received a prescribed weight loss plan, bag of dry veterinary therapeutic cat food formulated for weight loss, measuring cup, and food bowl or ball-type food toy. Body weight and BCS were checked monthly. Owners completed a monthly questionnaire to assess their cat’s QOL. Low-calorie vegetables were offered to 32 cats whose owners reported disruptive food-seeking behavior.

RESULTS
Of the 44 cats in the final analysis, 29 cats either lost ≥ 2 BCS points or achieved an ideal BCS. Owner-perceived QOL was higher at the final weigh-in, compared with that at the initial weigh-in. An effect of food toy versus food bowl on owner-perceived QOL was not detected. Of the cats offered vegetables, 28 cats would eat the vegetables with a palatability additive; 4 cats ate vegetables plain.

CONCLUSIONS AND CLINICAL RELEVANCE
Owner-perceived QOL was higher at the end of the study. Feeding overweight cats by use of a ball-type food toy did not influence owner-perceived QOL. Low-calorie vegetables can successfully be added to the weight loss diet to promote satiety; albeit, a palatability additive is likely needed. Further studies regarding feeding management for cats during a weight loss plan should be explored.

Abstract

Introduction: Recommended by the World Health Organization as the optimal way of infant feeding, maternal breast milk represents the best nourishment for the newborn baby during its first six months. The purpose of this study was to evaluate some of the Romanian mothers’ characteristics that can influence their attitude towards breastfeeding and food diversification.

Methods: A questionnaire about 32 questions, including demographics items and breastfeeding attitudes, was sent online (socializing platforms) in 2020 to mothers from all Romania districts. Our sample included at the end 1768 subjects, who fully completed the questionnaire. Statistical analysis was carried out using the GraphPad statistical software.

Results: The prevalence of breastfeeding for more than six months was only 32.18% in our group, and most of them were educated mothers who lives in urban areas (OR=2.76), were married (OR=1.98), had over 30 years old (OR=1.43) and have more than one child (OR=1.74).

Conclusions: We underline the importance of tackling in our future community interventions some of the socio-demographic characteristics of pregnant women (like groups education, good and accessible information about breastfeeding, young age, first pregnancy, or mothers from rural areas as well) in developing good habits of breastfeeding or complementary feeding, in order to improve their children health status and proper development.
The Cosine-Sine Functional Equation on Semigroups
Authors: Ebanks Bruce 
Published: October 2021

Abstract
The primary object of study is the “cosine-sine” functional equation f(xy) = f(x)g(y)+g(x)f(y)+h(x)h(y) for unknown functions f, g, h : S → ℂ, where S is a semigroup. The name refers to the fact that it contains both the sine and cosine addition laws. This equation has been solved on groups and on semigroups generated by their squares. Here we find the solutions on a larger class of semigroups and discuss the obstacles to finding a general solution for all semigroups. Examples are given to illustrate both the results and the obstacles.
We also discuss the special case f(xy) = f(x)g(y) + g(x)f(y) − g(x)g(y) separately, since it has an independent direct solution on a general semigroup.
We give the continuous solutions on topological semigroups for both equations.
