The issue of vaccine refusal: study of risky behaviour.

BACKGROUND: The aim of this study is to identify the influence of factors that determine the refusal of influenza vaccine among three subjects groups. METHODS: A survey was conducted amongst three high­risk groups in years 2018-2019 (Moscow, Russia). The survey involved 1,620 parents and pregnant women (group 1), 324 doctors (group 2) and 433 students (group 3). The analysis revealed a poor vaccine uptake among respondents of all three groups. RESULTS: According to the survey results, only 22.2 % of children and 13.8 % of adults were vaccinated against influenza. The group 2 showed higher rates for vaccinated adults and children, namely 36.7 % and 58.7 % , respectively. The lowest adherence to annual vaccinations was recorded in group 3 (only 17.3 %). There is also a negative correlation between adherence to vaccination and smoking -0.66), unhealthy diet -0.73), poor oral hygiene -0.61) as well as insufficient awareness of the need of influenza vaccine -0.81). CONCLUSION: The general lack of vaccination awareness has a fundamental role in forming a negative attitude toward influenza vaccine. It is necessary to conduct research to promote vaccination against influenza to improve vaccine uptake among high­risk groups, particularly in students (Tab. 1, Fig. 1, Ref. 32).

Examining the correlation between salivary cytokine concentrations and CRP in people experiencing social-cognitive stress.

OBJECTIVES: The study aims to determine the relationship of migraine and chronic tension-type headache (TTHs) with alterations in the salivary markers of inflammation . METHODS: The prospective study involved 75 patients . The concentrations of inflammatory markers (CRP, IL-1 ß, and IL-6) in migraine and chronic TTH patients were determined in distinct time points: headache-free period (interictal period), during headache (ictal period), day after headache attack. The STAI-Y (State Trait Anxiety Inventory - Y) and BDI (Beck Depression Inventory) questionnaires were used to measure the level of anxiety and depression in the interictal and ictal periods. RESULTS: The interictal levels of CRP, IL1-ß, and IL-6 were significantly higher in headache groups compared to healthy controls (p < 0.001). Differences in the ictal concentrations were even stronger. Twenty-four hours after headache attack, patients with migraine and chronic TTH experienced a decrease in CRP, IL1-ß, and IL-6 levels; yet, those levels were still higher compared with the interictal ones. The repeated analysis of variance revealed no significant statistical differences in CRP, IL-ß, and IL-6 levels between the migraine and TTH groups over time (p > 0.05). Statistically higher levels of anxiety and depression were seen in unhealthy groups (p < 0.01). CONCLUSIONS: The relationship of CRP, IL1-ß, and IL-6 concentrations with migraine and chronic TTH has been established. No statistically significant differences were found in the dynamics between migraine and chronic TTH groups. There was a direct correlation of migraine and chronic TTH with anxiety and depression.

Plant-parasitic nematodes affecting vegetable crops in greenhouses.

This work focuses on investigating plant-parasitic nematodes that affect greenhouse vegetables. The study took place in the Rostov region (Russian Federation) between May 2019 and May 2020 and involved 180 samples of soil and roots of 30 different vegetables in the families Cucurbitaceae (6), Solanaceae (8), Umbelliferae (8), Lamiaceae (4) and Allioideae (4) from 20 intensive farming locations. In this study, 11 nematode genera were detected. The most common genus was Meloidogyne, followed by Helicotylenchus, Pratylenchus, and Scutellonema. The highest Meloidogyne densities were detected in cucumbers, green peppers, carrots, eggplants, basil, and celery. Onions were not infected with Meloidogyne at all. Plant diseases caused by Pratylenchus, Scutellonema and Helicotylenchus were present in 29.7%, 51.5% and 81.6% of all crops examined, respectively. Xiphinema were found exclusively in carrots and celery, while Ditylenchus were only present in tomatoes and carrots (for each, the prevalence was 2.1%). The relative abundance of Meloidogyne, Helicotylenchus, and Pratylenchus was 58.3%, 10.4%, and 2.1%, respectively. As regards other genera, the relative abundance was less than 1%. The results show that soil properties are as important for the abundance, distribution and structure of the plant-parasitic nematode communities as the host plant. Findings may be helpful in improving the vegetable pest controls.
