Abstract Aim The increase in the number of publications in the hernia field has been higher than the most of our areas of surgery. COVID-19 pandemics has affected many elective surgical procedures like hernia repairs. We assumed that the declines in case volumes might cause some falls in related publications, and searched the literature in order to find the number of herniology publications before and during the pandemic. Material and Methods A systematic PUBMED search was done for three consecutive decades “1991-2000”, “2001-2010” and “2011-2020” by using the key words “inguinal and hernia”, “umbilical and hernia”, “incisional and hernia”, “mesh and hernia”, “laparoscopic and hernia”, “robotic and hernia”, and “experimental and hernia”. Later, a comparison of years 2019 and 202o was done. Results Although increases were detected for all searches with the key words, the largest rise was seen in publications related to “robotic and hernia”. Some undulations were recorded during the years, but the number of publications showed obvious increases decade by decade. A very small decrease was found in the number of publications for “experimental and hernia” only, however all other searches presented increases during the first year of the pandemic, 2020 in comparison with 2019. Conclusions The increases in the number of publications in hernia field continued during the last decade. COVID-19 pandemic did not cause a decrease in these publications the first year. We assume that year 2021 can be a more correct criteria in order to observe the potentially negative effect of the pandemic.

The purpose of the review is to summarize current literature data and the results of our own research on the analgesic and anti-inflammatory effects of acetylsalicylic acid, as well as the physiological mechanisms underlying them. This acid is the most studied reference representative of salicylates, which is convenient to consider the physiological effects characteristic in general for this group of chemical and medicinal products. Acetylsalicylic acid has analgesic properties against thermal pain and pain caused by electrical stimuli, as well as a pronounced anti-inflammatory effect. The realization of these properties depends on the peculiarities of aspirin metabolism in the body, ion and synaptic mechanisms for controlling the functional state of the cell, neurotransmitter systems of the сentral nervous system, and mechanisms of peripheral and сentral analgesia. Analgesic properties of acetylsalicylic acid founded not only in normal, but also in ultra-small doses. Various physical and especially chemical factors significantly change their effects. This increases the interest in studying the analgesic activity of salicylates and their physiological mechanisms, since such studies can serve as a basis for creating new non-steroidal anti-inflammatory drugs with low toxicity and high safety for patients, and improve the strategy of their practical use. Currently, the most detailed study of the physiological mechanism of analgesic and anti-inflammatory action of aspirin and its main metabolite – salicylic acid. However, it should be note that despite the abundance of existing data obtained in scientific studies of the effects of aspirin and its practical use, there are a number of unexplained aspects of the action of this drug, the mechanism of which has not yet been deciphered. The continuing interest in the effects and mechanisms of action of this drug and in connection with the expansion of its use evidenced by a consistently high number of scientific publications on aspirin in the most famous foreign and domestic publications. At the same time, the number of publications about aspirin is an order of magnitude higher than about any other drug known to humanity.

Abstract Background Antimicrobial resistance (AMR) is a global challenge that requires a “One Health” approach to achieve better public health outcomes for people, animals, and the environment. Numerous bibliometric studies were published on AMR in humans. However, none was published in food-producing animals. The current study aimed at assessing and analyzing scientific publications on AMR in food-producing animals. Method A validated search query was developed and entered in Scopus advanced search function to retrieve and quantitatively analyze relevant documents. Bibliometric indicators and mapping were presented. The study period was from 2000 to 2019. Results The search query retrieved 2852 documents. During the period from 2015 to 2019, approximately 48% of the retrieved documents were published. The article about the discovery of plasmid-mediated colistin resistance in pigs received the highest number of citations (n = 1970). The Journal of Food Protection (n = 123; 4.3%) ranked first in the number of publications while the Applied and Environmental Microbiology journal ranked first in the number of citations per document. The USA led with 576 (20.2%) documents followed by China (n = 375; 13.1%). When the number of publications was standardized by income and population size, India (n = 51.5) ranked first followed by China (n = 38.3) and Brazil (n = 13.4). The growth of publications from China exceeded that of the USA in the last 3 years of the study period. Research collaboration in this field was inadequate. Mapping author keywords showed that E. coli, Salmonella, poultry, Campylobacter, chicken, cattle, and resistant genes were most frequent. The retrieved documents existed in five research themes. The largest research theme was about AMR in Salmonella in food-producing animals. The most recent research theme was about the dissemination and molecular transfer of AMR genes into the environment and among different bacterial strains. Conclusion Hot spots of research on AMR in food-producing animals match the world regions of reported hot spots of AMR in animals. Research collaboration in this field is of great importance, especially with low- and middle-income countries. Data on AMR need to be collected nationally and internationally to implement the “One Health” approach in the fight against AMR.

Abstract Recent bumble bee declines have prompted the development of novel population monitoring tools, including the use of putatively non-lethal tarsal clipping to obtain genetic material. However, the potential side effects of tarsal clipping have only been tested in the worker caste of a single domesticated species, prompting the need to more broadly test whether tarsal clipping negatively affects sampled individuals. To determine if tarsal clipping reduces queen survivorship and colony establishment, we collected wild queens of Bombus vosnesenskii and clipped tarsi from a single leg of half the individuals. We reared captive queens and estimated survivorship and nest establishment success. We also clipped tarsi of workers from a subset of colonies across a range of body sizes. We found no consistent negative effect of clipping on queen survival. In the first year, clipped nest-searching queens suffered heavy mortality, but there was no effect on foraging queens. The following year, we found no effect of clipping on queen survival or establishment. Clipping did not reduce overall worker survival but reduced survivorship for those in the smallest size quartile. Implications for insect conservation Our findings suggest tarsal clipping does not have consistent negative effects on individual survival. However, our results varied with queen behavioral state, year, and worker size, suggesting differences within and among species and interactions with landscape stressors warrant further study. In the interim, we recommend researchers and conservationists minimize the use of tarsal clipping for sensitive species, populations, or small workers except in cases of exceptional scientific need.

Abstract Background The Israeli National Health Insurance Law provides permanent residents with a basket of healthcare services through non-profit public health insurance plans, independently of the individual’s ability to pay. Since 2015, several reforms and programs have been initiated that were aimed at reinforcing public healthcare and redressing negative aspects of the health system, and specifically the constant rise in private health expenditure. These include the “From Reimbursement-to-Networks Arrangement”, the “Cooling-off Period” program and the program to shorten waiting times. The objectives of this study were to identify, describe, and analyze changes in private hospitals in 1) the volume of publicly and privately funded elective surgical procedures; and 2) private health expenditure on surgical procedures. Methods Data on the volume and funding of surgical procedures during 2013–2018 were obtained from Assuta Medical Center, Hertzelia Medical Center, the Israeli Ministry of Health and the Central Bureau of Statistics. The changes in the volume and financing sources of surgical activities in private hospitals, in the wake of the reforms were analyzed using aggregate descriptive statistics. Results Between 2013 and 2018 the volume of surgical activities in private for-profit hospitals increased by 7%. Between 2013 and 2017, the distribution of financing sources of surgical procedures in private hospitals remained stable, with most surgical procedures (75–77%) financed by the voluntary health insurance programs of the health plans (HP-VHI). In 2018, following the regulatory reforms, a significant change in the distribution of financing sources was observed: there was a sharp decline in the volume of HP-VHI-funded surgical procedures to 26%. Concurrently, the share of publicly-funded surgical procedures performed in private hospitals increased to 56% in 2018.,. During the study period, private spending on elective surgical procedures in private hospitals declined by 53% while public funding for them increased by 51%. Conclusions and policy implications In the wake of the reforms, there was a substantial shift from private to public financing of elective surgical activity in private hospitals. Private for-profit hospitals have become important providers of publicly-funded procedures. It is likely that the reforms affected the public-private mix in the financing of elective surgical procedures in those hospitals, but due to the absence of a control group, causality cannot be proven. It is also unclear whether waiting times were shortened. Health reforms must be accompanied by a clear and comprehensive set of indicators for measuring their success.

The objectives of this study were to examine (i) the expectation for performance (EFP) in statistics of first year university students, (ii) the relative effect of previous mathematics performance (PMP), perceived statistical self-efficacy (SSE), and statistics anxiety (SA) for understanding these expectations, and (iii) whether students’ EFP scores differ based on sex and academic discipline. Findings point to average to high EFP in statistics, with no differences in these levels based on sex or academic discipline. PMP had little effect on students’ EFP, but, moderate effects on their levels of SA. While SSE positively affected both students’ SA, this measure produced a negative effect on their EFP in statistics. Both SSE and SA negatively affected students’ EFP in statistics, but with minimally higher levels for the latter.
