The Impact

Colostrum is a natural product, issued by both mammals and humans in the first week of lactation. Among different species, donkey colostrum is considered to have, in addition to a valuable composition in nutrients and immune factors, an outstanding similitude with human colostrum. In this context, and taking into account the scarcity of available data concerning the interaction between climate factors and colostrum quality, a trial was conducted aiming to identify the possible influence of environmental factors on donkey colostrum nutritional traits. A stock of 175 jennies from 7 farms located in Cluj and Sălaj Counties was analyzed over a 7-day postpartum period. During the experimental period, the daily temperature, humidity, and wind velocity data were collected. Strong positive correlations are reported between the studied colostrum nutritional traits (fat, protein and lactose). Testing the impact of some environmental parameters upon nutritional content of donkey colostrum indicated three factors that have an influence on the nutritional quality of donkey milk colostrum, labelled as: colostrum nutritional traits, environmental air traits and some colostrum nutritional traits, and climatic traits and some colostrum nutritional traits.

Among different species, donkey colostrum is considered as having, besides a valuable composition in nutrients and immune factors, an outstanding similitude with human colostrum. In this context, and taking into account the scarcity of available data concerning the interaction between climate factors and colostrum quality, a trial was conducted aiming to identify the possible influence of environmental factors on donkey colostrum nutritional traits. A stock of 16 jennies from 2 farms located in the County of Cluj, during a 7 days postpartum period was analyzed. During experimental period the daily temperature, humidity, and wind velocity data were collected. Strong positive correlations may be reported between fat and lactose, and fat and protein respectively, while moderate to strong correlation is emphasized between lactose and protein content of donkey colostrum. Testing the influence of environmental temperature, relative humidity, and wind velocity influence upon nutritional content of donkey colostrum, results the neglectable influence of the wind velocity, the negative influence of the heat stress upon all studied colostrum components, and complex influence of relative humidity, which has positive influence on fat and lactose increase when it increases, while its increase has negative influence on protein content of donkey colostrum.

AbstractCorona virus disease 2019 (COVID-19) has been declared a global pandemic and is a major public health concern worldwide. In this study, we aimed to determine the role of environmental factors, such as climate and air pollutants, in the transmission of COVID-19 in the Republic of Korea. We collected epidemiological and environmental data from two regions of the Republic of Korea, namely Seoul metropolitan region (SMR) and Daegu-Gyeongbuk region (DGR) from February 2020 to July 2020. The data was then analyzed to identify correlations between each environmental factor with confirmed daily COVID-19 cases. Among the various environmental parameters, the duration of sunshine and ozone level were found to positively correlate with COVID-19 cases in both regions. However, the association of temperature variables with COVID-19 transmission revealed contradictory results when comparing the data from SMR and DGR. Moreover, statistical bias may have arisen due to an extensive epidemiological investigation and altered socio-behaviors that occurred in response to a COVID-19 outbreak. Nevertheless, our results suggest that various environmental factors may play a role in COVID-19 transmission.

Abstract The main objective of the current study was to assess the impact of the water taken from the ‘Tunisian Refining Industries Company’ on meiobenthic nematodes, before and after a series of treatments in decantation basins followed by its discharge in Bizerte bay, Tunisia. The comparison of environmental parameters of the two types of water was clearly indicative of an improvement in the quality of treated waters after a significant reduction in their loads in hydrocarbons. Overall, the water retained a good quality after being treated by ‘Tunisian Refining Industries Company’ before discharge in the sea. At the end of the experiment, differential responses were observed according to the richness of sediment in organic matter and hydrocarbons. Thus, it was apparent that the nematode assemblage exposed to the treated waters was closer to controls and associated to higher values of abundance, than that under untreated ones. It was also assumed that the species Microlaimus honestus De Man, 1922, Paramonohystera proteus Wieser, 1956 and Cyartonema germanicum Juario, 1972 are sensitive bioindicators of bad environmental statues and of hydrocarbon presence in the environment. On the other hand, Metoncholaimus pristiurus (Zur Strassen, 1894) Filipjev, 1918 would rather be classified as a positive bioindicative species of this type of pollutants.

Introduction: The impact of periodontal disease on oral health–related quality of life (OHRQoL) has often been investigated from a quantitative research perspective, which is based on clinical findings and an OHRQoL questionnaire. Very few studies have examined the issue from the view of qualitative research. To our knowledge, there have been no previous qualitative studies focusing the effect of periodontal disease on OHRQoL in Indonesian older people. Objectives: To explore and understand the impact of periodontal disease on the OHRQoL of older people as a subjective reflection in relation to periodontal disease experiences. Methods: Semi-structured interviews were conducted in a sample of 31 older people with generalized chronic periodontitis. Thematic analysis was used to identify the key issues in participants’ accounts. The analysis was undertaken by 2 independent coders to ensure reliability. To achieve thematic saturation, successive interviews were undertaken until 5 sequential interviews did not bring new themes. Results: Participants reported the negative effects likely related to periodontal disease. The impacts of periodontal disease were described by these older people as affecting more than pain, physical discomfort, and physical function restrictions. Periodontal disease also affected their psychological and social aspects of daily living. In addition, this study identified themes related to individual and environmental factors that may modify and personalize periodontal disease experiences. Furthermore, this study identified a misleading belief that problems related to periodontal disease were a normal part of aging, which might influence individuals’ expectations toward oral health. Relatedly, participants frequently reported that the progression of tooth mobility to tooth loss was an inevitable part of the aging process. Conclusions: Periodontal disease negatively affected participants’ OHRQoL. It is fundamental to understand older people’s perceptions toward their periodontal disease as well as individual and environmental factors that may have an influence on their periodontal disease experiences. Knowledge Transfer Statement: This study is a reflection of Indonesian older people’s subjective periodontal disease experiences. Therefore, the present study can be used to understand older people’s perceptions, attitudes, behaviors, and experiences toward periodontal disease and how this disease may affect their quality of life. This study also highlights a widespread and misleading belief that oral problems related to periodontal disease are an inevitable part of aging in this study population.

Abstract The water quality of the Sunter River in Jakarta was classified as heavily polluted due to activities around the river, both domestic and non-domestic. As one of the environmental parameters for water quality, the presence of Escherichia coli (E. coli) is normally found any natural environment, and under certain conditions it can become resistant to antimicrobials due to genetic mutations. The mutated E. coli produces Extended Spectrum Beta-Lactamase (ESBL) enzymes and has a higher survival ability in antibiotic-contaminated river water, thus potentially endangering public health. This study was aimed to evaluate the effect of environmental factors on the abundance of ESBL producing E. coli and their resistance to antibiotic cefotaxime. Sampling was conducted in six locations representing the upstreams and the downstreams of Sunter River, following the Global Surveillance guidelines. E. coli strains were isolated using Tryptone Bile X-glucuronide (TBX) agar medium (with and without the addition of cefotaxime 4μg/ml) and the antibiotic sensitivity test of ESBL E. coli was conducted by performing a double-disk test. The results showed that the highest average abundance of ESBL E. coli was found in the sample taken from Sindang Station (904.24 x 104 colony per unit (CFU) / 100 mL) and the lowest was from Sunter Station (1,58 x 104 CFU / 100 mL). The results of the Bivariate Pearson correlation analysis showed that temperature, pH, and salinity were negatively correlated with the abundance of ESBL-producing E. coli bacteria.

One of the main challenges of the future is the strengthening impact of environmental factors on economic development, in particular, environmental threats, climate change, waste minimization and reduction of СО2 emissions. At the present stage, achieving sustainable economic development has become an important item on the global agenda. The purpose of this article is to develop the theoretical foundations of the process of greening in the economy and substantiate practical approaches in Ukraine to overcome global climate challenges. To achieve this goal, the author used retrospective research methods, and abstract-logical, economic-statistical and systematic approaches. Based on the analysis of scientific works of foreign and domestic scientists, the article deepens the theoretical foundations of the concept of greening. In particular, it is established that this concept characterizes the improvement of environmental parameters of production through the introduction of technological, organizational and managerial innovations that increase the efficiency of natural resources, reduce man-made impact improve the quality of the environment and increase the level of environmental education and environmental culture of the population and industrial staff. The results of the study showed that in modern conditions the concept of sustainable dependence of the economy on environmental factors has been formed, which is supplemented by the problem of solving global challenges of mankind. This requires the introduction of new economic approaches to addressing the global challenges posed by climate change, among which the introduction of the principles of circular economy is important.

Abstract In recent years, several studies have been developed to understand the impact of fermentation on the final quality of coffee and have indicated that postharvest processing could be a determinant of quality. However, a trend has appeared as a scientific counterpoint, indicating that the interactions between soil, fruit, altitude, and slope exposures with respect to the Sun are important to understand the behavior of the microbiome in coffee. Studies on the microbiota of coffee have addressed its role during the fermentation process, however the knowledge of indigenous microorganisms harbored in fruits and soil of coffee trees growing in fields are essential, as they can contribute to fermentation. Therefore, the aim of this work was to evaluate the influence of topographic and edaphic factors on the bacterial and fungal communities present in the soil and in the fruits of Coffea arabica trees. Samples of fruits and soil were collected from different growing areas at different altitudes and soil conditions. The microbial DNA was extracted and sequenced. The results showed the contribution of environmental factors in the structure of bacterial and fungal communities. The richness, evenness and diversity of the mycobiome and bacteriome were higher in the soil than in the fruits, independent of altitude. In addition, coffee trees at higher altitudes tended to have more bacteria shared between the soil and fruits. The co-occurrence/co-exclusion network showed that bacteria-bacteria connections were greater in higher altitudes. On another hand, fungi-fungi and fungi-bacteria connections were higher in low altitudes. This was the first study that evaluates in deep the influence of environmental factors in the microbiota habiting fruits and soil coffee trees, which may affect the coffee beverage quality.

ABSTRACT The aim of this work was to evaluate the microbiological quality of striped venus clams (Chamelea gallina L.) harvested in the north Adriatic Sea during an 8-year monitoring period. A total of 387 samples were analyzed to assess the presence of Escherichia coli. Environmental parameters (salinity, pH, dissolved oxygen, seawater temperature, and freshwater outflow) were collected to find out a possible relationship between the E. coli counts and environmental factors. The results evidenced that the microbiological quality of the clams was good, with only about 5% of the samples not complying with European and Italian regulations for this product, that is, with E. coli counts higher than 230 most probable number (MPN) per 100 g of flesh and intravalvar liquid. Statistical analyses revealed a relationship between microbial contamination and the season and water temperature, probably due to the difference in the filtering activity of the mollusks. However, the main factor affecting the E. coli concentration in the clams turned out to be the flow rate of Marecchia, the major river that reaches the sea in the area of harvesting. In fact, a model fitted to evaluate the probability of finding a higher E. coli count in relation to the environmental parameters evidenced that it was an increase of the level of the Marecchia led to a higher probability of elevated E. coli contamination. This result could be explained by the higher supply of both nutrients and coliforms (including E. coli) when the river is higher and by the anthropogenic characteristics of the lands crossed by the river.
