ABSTRACT
This paper aims to analyze the research on the current situation of water-saving agriculture development in Europe. Water-saving agriculture in Europe started early, governments and farmers in various countries have a strong awareness of water-saving in agriculture and have achieved certain results. Due to the global spread of the COVID-19 pandemic, the lack of up-to-date field research, the complexity of various agricultural disciplines and categories, and the lack of information sharing, the current cognition of recent progress in the development of water-saving agriculture in Europe is not comprehensive enough. This paper selects four representative European countries: Spain, Germany, Italy, and Denmark as the research objects. Based on the existing research of Chinese and Western scholars, this paper analyzes and studies the current situation of water-saving agriculture in Europe. It has far-reaching significance for other countries in the world to have further development in water-saving agriculture and to protect water resources.
ABSTRACT
Aquaculture production in Bulgaria has increased over the last decade, reaching 16 442 tonnes in 2019. Fish production has doubled in comparison with 2007, while that of mussels has increased tenfold. The Bulgarian contribution to EU aquaculture production has been increasing significantly in both volume and value over the years, making up 1.15% of the volume and 1.0% of the value of EU production in 2019. Freshwater aquaculture accounts for 78% of total production. Common carp dominates with about 29.4% (4836 t), followed by rainbow trout with 29.2% (4820 t) in 2019. The cultivation of sturgeon species and caviar production are among the most dynamically developing aquaculture segments. Mariculture in the Black Sea has increased in recent years, with the production of Mediterranean mussel reaching 2932 tonnes in 2019. An average of 405 farms operated during the period 2010-2019. Four regions (Plovdiv, Stara Zagora, Burgas and Montana) account for 50% of the total fish production. Pond aquaculture is the dominant technology used in Bulgaria, and it serves as the basis for numerous other activities, including management of fish stocks in various water bodies mainly for recreational fishing. Approximately 35 net-cage farms currently operate in bigger dams. Recirculating fish farms output made up only 0.15% of the total amount of aquaculture for the period 2010-2019. The aquaculture sector exhibited difficulties in recovering from the financial crisis of 2007-2008, manifested by a slow growth for the period 2010-2014. From 2015 to 2019 there has been a significant growth, manifested in a sharp increase of total revenue and profitability, especially among the larger enterprises in the sector, as well as an increase in the number of employees, and the labour productivity. As a result, in 2019 the registered total revenue per enterprise and total revenue per employee were more than double the respective figures for 2010. The profits of larger enterprises increased more than three times on average, but smaller entities, micro-enterprises with less than 5 employees, operated at the border line between profit and loss. The COVID-19 crisis could have lasting consequences. Despite EUR 1.2 million direct payments in the sector in 2020, there has been a significant drop in the export of aquaculture products. Consumption of fish and other aquaculture products remains low compared to those in the other EU countries.
ABSTRACT
The various crises are having a significant impact on the entire food sector and are changing the attitudes of Europeans as well as policies on the importance of food security and sustainably produced quality and safe food for consumer health. The paper focuses on the consumer's fear of food security for the time of the first wave of COVID-19 and the associated concern for food security in the future and the changes in consumer behaviour. The online survey in Slovenia was conducted in June 2020 using a "snowball" method. The sample included 490 individuals. The results showed that both measured forms of fear (i) fear over food security during the first wave of COVID-19 crisis, and (ii) fear over food security in the future were statistically significant, moderately strong and positively associated with almost all forms of self-perceived behaviour change caused by the COVID-19 crisis. The respondents focused more on buying locally produced and processed food, food stockpiling and decreasing food waste. Only minor changes were expressed with regards to their food purchasing channels, with the elderly, the highly educated and those who classified themselves in a higher social class buying more often directly from farmers. In the future, the results of this research should be compared with other countries and the impact of an individual's economic situation and the impact of promotional campaigns on agricultural products on changing consumer behaviour should also be analysed in more detail.
ABSTRACT
Patients on maintenance hemodialysis (MHD) are highly susceptible to SARS-CoV-2 and with high mortality rates due to Coronavirus disease 2019, mainly because of the older age in this group of patients, comorbidities, compromised immune status due to uremia, as well as inability to keep social isolation because of the necessity for regular physical presence in dialysis facility. Several retrospective studies of patients on MHD in Europe, America and Asia, show high susceptibility to SARS-CoV-2 in this group of patients with very high rates of critical course of the disease and high mortality rates, reaching more than 40% The aim of this retrospective observational study was to identify risk factors among patients on intermittent hemodialysis for infection with SARS-CoV-2 as well as predictors of severe COVID-19 and fatal outcome. Materials and methods. We analyzed 69 patients receiving intermittent dialysis in Aleksandrovska University Hospital - Hemodialysis Unit. 34 of them have been tested positive for SARS-CoV-2 in the period from September 2020 (when the first case of the disease was registered for our dialysis center) up to March 2022, and are compared with a control group of 35 dialysis-dependent patients without COVID-19. Data about comorbidities, main laboratory and radiologic findings, need of hospitalization and treatment in ICU, as well as data for conducted treatment, are collected from electronic medical records. To identify predictors of severe COVID and poor outcome we compared the group of survivors with the one of non-survivors. Results. There are no significant differences between patients on MHD with and without COVID-19 except higher frequency of COPD and hypoproteinemia in the positive group. Older age, female gender, history of smoking, lymphopenia with neutrophilia, treatment in ICU and need of mechanical ventilation, signs of malnutrition - hypoproteinemia and lower levels of serum creatinine, are risk factors for severe disease and fatal outcomes. Conclusions. The course of COVID infection in dialysis-dependent patients is severe and with high mortality rate, in line with other studies worldwide. Malnutrition is the main risk factor for COVID and also main predictor for poor outcomes.
ABSTRACT
Coronavirus disease 2019 is a pandemic disease, which commonly presents with fatigue, loss of smell, fever and ground-glass opacities on diagnostic imaging of the lungs. After the first few months of the pandemic, we noticed a tendency for audio-vestibular complaints on out-patient visits post-hospitalization for COVID-19. Objective. The aim of this study was to study the prevalence of audio-vestibular complaints in COVID-19. Materials and methods. This study included 57 patients with audio-vestibular complaints during and after hospitalization for COVID-19 at University Hospital Kaspela in Plovdiv, Bulgaria. The patients underwent both auditory and vestibular tests, as well as a computed tomography of the cranial brain. Results. The ratio of males to females was 1,35:1, with most belonging to the age group of 51 to 70 years (63,2%). All 57 patients had sudden hearing loss - unilateral in 36 (63,2%) and bilateral in 21 (36,8%), while 17 patients (29.8%) additionally had subjective tinnitus. Forty-eight patients (84,2%) had vestibular complaints - general dizziness in 46 (95,8%) and rotatory vertigo in two (4,2%). Two patients had spontaneous nystagmus (3,5%), 43 (75,4%) - saccades, and 25 (43,9%) - smooth pursuit and gaze disturbances. Romberg with closed eyes was positive in two patients (3,5%), and Fukuda lateralized to the healthy ear also in two patients (3,5%). Dix-Hallpike was positive in one patient (1,8%). The video head-impulse test was positive in two patients (3,5%). Vascular encephalopathy was found on computed tomography in 33 patients (57,9%). Conclusions. Coronavirus disease 2019 may be associated with vestibulocochlear nerve damage, and in most cases, it is an isolated injury to the auditory nerve. Complaints of dizziness are most likely due to vascular changes in the central nervous system.
ABSTRACT
This is the first study to examine the differential impact of Croatian and European economic policy uncertainty indices while controlling for the real effective exchange rate and industrial production on international tourist arrivals for the seven coastal counties of Croatia and the country as a whole. The Toda-Yamamoto long-run causality modeling approach with a Fourier approximation is employed to capture structural shifts. This approach is particularly useful in light of the disruption from the COVID-19 pandemic on the tourism sector. The results show unidirectional causality from both Croatian and European economic policy uncertainty indices to international tourist arrivals with the impact of the economic policy uncertainty indices negative and statistically significant across the respective coastal counties. Moreover, the findings show that European economic policy uncertainty exhibits a greater adverse impact on international tourist arrivals relative to Croatian economic policy uncertainty.
ABSTRACT
Shingles is a viral skin disease caused by the Varicella Zoster virus. We report varicella zoster virus reactivation in three long-time athletes after vaccination with a COVID-19 mRNA vaccine. The three athletes had no evidence of immunosuppressive conditions or other illnesses, and all three did not suffer from COVID-19. The first patient is a 21-year-old athlete with an 8-year sports career. He developed shingles four days after being vaccinated against COVID-19. The second athlete is 20 years old and has been actively involved in fitness for ten years. He was diagnosed with herpes zoster three days after the vaccination. The third athlete is 23 years old and has been actively involved in sports and fitness since the age of 6;he was diagnosed 4 days after the vaccination against COVID-19. All three were diagnosed by a dermatologist. Discussion: The relationship between the development of herpes zoster after the administration of a vaccine against COVID-19 has been the subject of many studies worldwide, but the occurrence of herpes zoster after Covid-19 vaccination in athletes is described for the first time. Our team did not find a report of a case of an athlete with herpes zoster after vaccination for COVID-19 anywhere, which motivated us to describe the above three cases.
ABSTRACT
In recent years, a number of complications have been observed as a result of uncontrolled antibiotic treatment. One of them is gastrointestinal dysbiosis. Not infrequently it is the cause of pseudomembranous colitis, a disease with a remarkably high associated mortality. It can be severe and requires serious medical care. This report presents a clinical case of a patient who developed the disease pseudomembranous colitis after antibiotic treatment for a Covid infection. The aim of the report is to define and present in a systematized manner the nursing care provided in the specific case. The daily analysis of the patient's condition allows to offer complex, adequate and individual nursing care, which, in addition to meeting her needs, also aims to alleviate her condition.
ABSTRACT
Various Slovenian hospitals were recruited to treat COVID-19 patients in Slovenia during the COVID-19 epidemic. Centrally coordinated hospital utilisation - depending on the needs, available hospital bed capacity, and considering the professional orientation of individual hospitals - left these facilities with different experiences. We present our experience and COVID-19 treatment management during the fourth epidemic wave in our peripheral, pulmonary-oriented hospital, representing the first treatment quality analysis of these patients in Slovenia. The basic hospitalization characteristics were analysed using integrated Birpis information system solutions and the electronic temperature-therapeutic charts (eTTL) review. The quality of management was assessed through adherence to professional recommendations. The analysis was carried out with the in-built statistical functions of Microsoft Excel software. 99 patients (58 women, 41 men) aged 67.9 years were hospitalised for an average of 8.1 days. The majority were residents of our region (61%), unvaccinated (61.6%), and experienced a severe form of the disease with the need for oxygen supplementation (88.9%). The majority received steroids (73.7%), antibiotics (68.7%) and vitamin D (71.7%), to a lesser extent specific therapy (remdesivir 25.3%, combination casirivimab/imdevimab 2%, tocilizumab 1%). No adverse reactions were noted. 17 people died (total mortality rate 17.2%). There was no infection transmission among the COVID department staff. Results show successful treatment of patients with COVID-19 in Topolsica Hospital. They also suggest the possibility of further improvements, particularly in prescribing antibiotic therapy.
ABSTRACT
Infectious bronchitis virus (IBV) is among the most impactful poultry pathogens, whose control, based on biosecurity and routine vaccination, is hampered by the existence of countless genetic variants sharing poor cross-protection. A retrospective study was conducted on IBV positive samples collected in Italian broiler farms from 2012 to 2019. In 2015, the adopted vaccination protocol shifted from a Mass and 793B-based vaccines to the administration of Mass and QX vaccines, allowing to study how changes in vaccination strategies may affect IBV epidemiology, control and diagnosis in the field. The most frequently detected lineages were QX (70.3%), 793B (15.8%) and Mass (11.9%). The relative frequencies of QX and 793B detections remained stable throughout the study, while Mass detections significantly increased after the vaccination change. Rather than to an actual growth of Mass population size, this finding may be attributable to different vaccine interactions, with Mass strains being more frequently concealed by 793B vaccines than by QX ones. Based on the obtained results, the two vaccination protocols appear to be similarly effective in fighting IB outbreaks, which in the last decade have been caused primarily by QX field strains in Italy. These results indicate that vaccination strategies may significantly affect IBV epidemiology and diagnosis, and should therefore be considered when choosing and interpreting diagnostic assays and planning control measures.
ABSTRACT
The paper presents the reaction of the Romanian cereal market to the disruption of trade flows caused by certain shocks, such as the COVID-19 pandemic, which lead to changes with high impact on the functioning of this market, representing an important test for the resilience of the sector. Due to trade liberalization in global markets, including agri-food markets, the competitiveness of exports has become increasingly important, contributing to the creation of the country's competitive advantage. Any restrictions to trade in agri-food products can distort trade flows, and this disruption will have an impact on supply and prices. Maintaining a balance between imports and exports is essential to ensure domestic market stability. International trade in agri-food products plays an important role in global food security. The results show that Romania mainly exports unprocessed agricultural products, with cereals having the largest share in the export structure, cereal supply is dependent on climate change, yet it is one of the products with the lowest volatility. The cereal market shows a more elastic reaction to price responses, even though demand for staple foods is generally inelastic.
ABSTRACT
Objective: The study aimed at identifying the influence of socio-demographic factors on perceived stress during the first and the second "waves" of the COVID-19 pandemic among patients with depression and anxiety in remission compared to controls. Method: The study was designed as case-control, cross-sectional and non-interventional, and included 60 outpatients with depressive and anxiety disorders in remission and 60 controls with or without family history of affective disorder. A self-assessment scale (Perceived Stress Scale, PSS-10) was used to evaluate perceived stress. The remission was objectified by the Clinical Global Impression scale (CGI-S 2) and a questionnaire about the socio-demographic features and clinical characteristics of the disorders was completed. Results: By using multiple logistic regression, it was found that the diagnostic category and/or the relevant family history did not predict higher levels of perceived stress during the COVID-19 pandemic (p > 0.05). Females were associated with higher risk of moderate or high stress (OR=2.613, p=0.017), as well as those working from home during the pandemic (OR=4.00, p=0.026). Conclusions: Addressing the COVID-19 effects on mental health in a biopsychosocial manner, the study shows the impact of socio-demographic factors such as gender and work environment in times of a psychosocial crisis. The lack of differences in stress perception by the patients in remission and healthy controls implicates the importance of adequate maintenance treatment and easy access to mental health services in times of crisis.
ABSTRACT
Introduction: SARS-CoV-2 infection has affected more than 683 million people worldwide with 6.8 million deaths. Unfortunately, Bulgaria is one of the most severely affected European Union (EU) member-states with one of the highest mortality rates. Aim: The study aims to provide a description of the demographic characteristics, discharge rate, and fatality rate of COVID-19-diagnosed patients in one region of Central South Bulgaria in 2021. Materials and methods: A retrospective nested case series study was conducted among patients hospitalized with a confirmed diagnosis of SARS-CoV-2 infection between January 1st and December 31st, 2021. Anonymized patient data on age, sex, admission and discharge dates, treatment, and the outcome was collected from hospital electronic patient records and analyzed using descriptive statistics. Results: Data from 1630 (51% male) patients were identified. The mean age was 63.64 years (+or-15.23). 1342 (82%) of the patients were discharged. The mean age of the diseased was 70.88 years (+or-10.05). 1455 (89%) patients received only symptomatic therapy, 155 (10%) patients were treated with remdesivir (VekluryR), 11 (1%) patients were treated with casirivimab/imdevimab (RonapreveR) and 9 (1%) patients were administered regdanvimab (RegkironaR). Conclusions: The study results demonstrate that Bulgarian patients with COVID-19 were treated according to the best global and national evidencebased guidelines. Lethality and discharge rates are in concordance with global trends and outcomes.
ABSTRACT
Romania ranks first in the European Union for the production of sunflower seeds, third for the production of soybeans and seventh for the production of rapeseed. The paper aims to analyse the effects produced by the COVID-19 pandemic on the evolution of the oilseed sector in Romania. Thus, the following indicators were analysed: evolution of areas under oilseeds, total oilseed production and average yields, as well as the volatility of selling prices for oilseeds. The results of the study reveal that Romania has been the largest producer of sunflower seeds in the European Union. The average yields in sunflower, soybeans and rapeseed have shown great variations in the analysed period. According to Eurostat data, it can be noticed that although Romania is the third large producer of oilseeds in the EU, the average yields continue to be low compared to those from other large EU producers. Yields are also among the most volatile in the EU. The selling prices for soybeans showed a higher increase in the year 2020 than in 2019 in Romania, compared to the increase in the average selling prices of the EU-27 (+9.89%). The selling prices for rapeseed also had a higher increase in 2020 than in 2019 in Romania, compared to the increase in the average selling prices of the EU-27 (+2.31%).
ABSTRACT
For a better understanding of the COVID-19 pandemic impact over the medical education methods used by medical personnel, we have made a study using a standard form in which we have applied targeted questions regarding the methods used in medical education before and after the pandemic. This study followed the motivation and selection criteria of medical education forms before and after the pandemic, the advantages and disadvantages noed by attendees through onsite and online, also including suggestions for the future of medical education. The number of participans in online courses and the time assigned for online medical education has increased, compared to the period before pandemic. During the pandemic, has been recoreded a reorientation of participans on online platforms, following the utilization of those platforms which allow uploading files as well as free interaction between students and lecturer. The advantages and disadvantages, noted in medical personnel training, are counterbalanced in both of education online - onsite forms (exemple: the interaction with the lecturer and also between the students at medical meetings, has been the main advantage of medical education onsite and the major disadvantage of online education). The majority of study participants consider, for the futere, the combined use of both online and onsite professional training methods, and, therefore the participans can decide on what method of education should use.
ABSTRACT
Purpose: The pandemic of COVID-19 led to considerable challenges with respect to people's health, dietary behavior and satisfaction with life. This study aims to investigate perceived stress levels, in relation to diet quality and life satisfaction in Greek adults, during the COVID-19 lockdown. Design/methodology/approach: This is a cross-sectional study which took place in Greece in the course of the strict lockdown period, in the third COVID-19 wave. A sample of 2,029 adults aged 18 years and above participated in an online survey. The questionnaire consisted of questions on sociodemographic and anthropometric characteristics. The Perceived Stress Scale, the Satisfaction with Life Scale and the Mediterranean Diet Assessment Tool were also used. Findings: Linear regression has shown that women (p < 0.0001), younger individuals (p < 0.0001), obese individuals (p = 0.047), those with lower levels of satisfaction with life (p < 0.0001) and lower adherence to Mediterranean diet (p = 0.0001) were positively associated with higher levels of stress. Originality/value: To the best of the authors' knowledge, this is the first study conducted in Greece aiming at investigating concurrently, levels of perceived stress, with respect to levels of satisfaction with life and diet quality in adults, during the lockdown period of the COVID-19 pandemic.
ABSTRACT
The international multicentre study HBSC (Health Behaviour in Schoolaged Children) conducted since 1983 in collaboration with the World Health Organization, has been adopted in our country as the national adolescent health surveillance system since 2017. The main aim is to describe and understand health-related behaviour in 11-, 13- and 15-year-olds in approximately 50 countries between Europe and North America. The study investigated different aspects, such as nutrition, risk behaviors, school and family life and social media use. In addition, the latest survey involved 17-year-old adolescents and included a section on the impact of the COVID-19 pandemic.
ABSTRACT
One of the most important sectors of tourism globally is cruise tourism, as is giving a leisure experience to cruisers who are traveling across different destinations. It is also one of the most growing sectors in the tourism industry as is becoming increasingly popular. In this review study, conducted employing thematic analysis and thematic synthesis, the authors aim to approach the COVID-19 crisis era financial investments of dominant cruise companies as a component of global economic growth. Nowadays, the cruise industry operates big cruise ships as is contrary to the cruise industry back in 1960s. This study finds that the biggest cruise companies line up investment plans to renew their cruise fleet with larger, more modern, and environmentally friendly ships, borrowing from favorable financing sources. In other words, the companies are trying to introduce specific strategies to maintain their business growth, by investing in building new vessels with the target of expanding their current fleet with cruise ships with better capacity.
ABSTRACT
During the COVID-19 pandemic, with events and travel on hold, all sectors of the hospitality industry have been challenged to reimagine their business models to keep their businesses profitable, even by rethinking them towards sustainability. While there have been positive signs of recovery and increases in hotel bookings, the pandemic has dramatically changed consumer demands and expectations, forcing companies to adapt their offerings accordingly, so hotels have gotten creative over the past 2 years in repurposing and selling rooms and spaces for events, after the negative impact caused by the SARS COV 2 pandemic. The purpose of the paper is to highlight the actions undertaken by tourism operators in order to reinvent the services offered as a result of the pandemic.
ABSTRACT
Introduction: The pandemic caused by the SARS-CoV2 virus is a challenge for global health systems and generates problems both in socio-economic and individual levels. Objectives: The aim of the study was the general presentation of viral pathogenesis, its transmissibility and maternal-fetal complications that occur following SARS-CoV2 virus infection that have been identified in the literature and its prevention. Results: This paper is a systematic review that includes a summary of the literature using the PubMed database with a selection of studies from January 2020 to July 2022. Many studies have reported a slightly increased severity of COVID-19 among pregnant women compared to non-pregnant women due to complications during pregnancy that resulted in miscarriages, premature births or preeclampsia. Conclusion: Therefore, further investigations are needed to elucidate how COVID-19 affects pregnant women and newborns as well as the long-term impact of SARS-CoV2 infection on women who have given birth, regardless of immunological status at birth.
