The objective of the study was to compare health status of harvested grain of spring barley cv. Rudzik, Rodos, Start and Maresi cultivated in organic system and cv. Damazy grown in an organic farm. Analyses showed that prevalent pathogen on grain was <i>Bipolaris sorokiniana</i> isolated from 48% of grains. Fungi from genus of <i>Fusarium</i> were obtained less numerously, from 27% of grains and were represented mainly by <i>F. poae</i> and <i>F. avenaceum</i>. Microscopic analysis of <i>F. poae</i> was confirmed by PCR analysis. All cultivars were intensively diseased by <i>B. sorokiniana</i>, thus it is impossible to show a cultivar especially recommended for this system, where <i>B. sorokiniana</i> can be serious problem. However cv. Damazy showed relatively the lowest infestation by <i>B. sorokiniana</i> and it also was not more intensively diseased by <i>Fusarium</i> spp. It is very important in nutrition aspect because these fungi can be dangerous for both human and animal health due to their abilities to produce mycotoxins.

Background. Diseases and pests cause great damage to barley stands and harvests. Harvest losses from harmful organisms reach 25–30%.Materials and methods. During 2017–2020, 46 spring barley cultivars from the VIR collection, listed in the State Register for Selection Achievements, were studied for their resistance to fritfly, net and spot blotches, brown rust, and powdery mildew. The tests were carried out in the field with provocative colonization by fritfly and under natural infection pressure of leaf pathogens.Results and conclusions. In 2017, net blotch predominated over other diseases. In 2018, there was an epyphytotic outburst of spot blotch, and cultivars with weak development of this disease were identified. In 2019 and 2020, the incidence of brown rust and powdery mildew was significant, and the virulence of fritfly increased greatly in the same years. Field tests resulted in identification of 3 barley accessions resistant to fritfly: ‘Odon’ (k-31118, Buryatia), ‘Miar’ (k-31203, Orenburg Province), and ‘Omsky 99’ (k-31230, Omsk Province). Cv. ‘Posada’ (k-31245, Germany) was weakly affected by fritfly, brown rust and powdery mildew. Cultivars were selected for their low susceptibility to powdery mildew (up to 5%): ‘Chiraz’ (k-31131, Denmark), ‘Cheerio’ (k-31297, Denmark), and ‘Odyssey’ (k-31333, England), and brown rust: ‘Chiraz’ (k-31131, Denmark), ‘Eifel’ (k-31249, France), ‘Ursa’ (k-31339), and ‘Sunshine’ (k-31129, Germany). Such long-term assessment results can be used in breeding programs to develop cultivars with group or complex resistance to harmful organisms.

The article presents and analyzes data of competitive varietal testing of promising varieties and lines of spring barley for yield and brewing qualities. Field studies were conducted in 2014–2017 on dark gray forest heavy loam soil. Agrochemical parameters are total nitrogen – 0.24%, humus content in a layer of 0-40 cm (according to Tyurin) – 5.19%, hydrolysis nitrogen – 123.5 mg / kg, salt extract pH – 4.92 mg-eq / 100g; labile phosphorus - 34.6 mg / 100g, labile potassium – 20.0 mg / 100g. The forerunner is winter wheat. Meteorological conditions in the years of research differed from each other and from the average long-term value. Barley samples were assessed by the protein content in the grain (GOST 10846-91), extract content (GOST 12130-77), weight 1000 grains (GOST 10842-89). Ecological plasticity was determined by the method proposed by E.D. Nettevich, A.I. Morgunov and M.I. Maksimenko, stability index (Ľ) by A. A. Gryaznov, indicator of stability level (Puss) by E. D. Nettevich and A. I. Morgunov. The main measure for assessing quality indicators is protein content. Many other biochemical and technological features of grain depend on its level. The experimental data convincingly testify to the significant influence of the soil and climatic conditions on the yield and, especially, on the brewing qualities of barley in the conditions of the Central Region of the Nonchernozem Zone. According to the studied traits, new valuable varieties Nadezhny, Sir, Noble and selection lines 141 / 1-09 h 746, 23 / 1-10 h 784, distinguished by high adaptability and resistance to adverse environmental factors, have been identified.

Abstract Background In order to provide efficient public health decisions making, it is crucial to obtain reliable and recent data on the state of health of the population. For that purpose, a web-platform for the dynamic monitoring of the health status and well-being of the population is being developed in the Geneva canton. Methods Using a dedicated website, recruitment will be carried out over 5 years so as to enroll up to 20 000 volunteers, resident in Geneva and aged ≥ 18 years, followed-up for at least 10 years. Once connected to the website, participants will fill a general self-administered questionnaire on their socio-demographic and lifestyle characteristics, anthropometry, health status, physical activity and diet. Environmental, behavioral and occupational exposures will also be evaluated via more specific questionnaires. Current addresses of residence will be geocoded and linked to geographical databases to passively gather information on noise, air pollution, green areas, and other exposures. Surveillance of health events will be implemented via yearly self-administered on line questionnaires and potentially via passive linkage to medical databases (medical file) and health registries with the participants' consent. For a subsample of volunteers, biochemical samples and biomarkers will be collected. Results The pilot study shows that the project is feasible, potentially cost-effective but requires innovative methodologies for ensuring long term follow-up. Different communication strategies used for recruitment and long-term participation need to be implemented ensuring trust from participants, different levels of health literacy and the need of justice. Conclusions Specchio is a new project aimed at setting up a digital longitudinal health study in Geneva. Challenges concerns the determinants of participation, recruitment and attrition, quality of data and ethics. Long-term funding by the Directorate General of Health Geneva is currently under evaluation. Key messages This digital longitudinal health study will enable dynamic monitoring of the health status and well-being of Geneva residents and will enable efficient public health decision making. Specchio is a new project funded by the Directorate General of Health Geneva.

Assessment of plant height is an important factor for agronomic and breeder decisions; however, current field phenotyping, such as visual scoring or using a ruler, is time consuming, labour intensive, costly and subjective. For agronomists and plant breeders, the most common method used to measure plant height is still a meter stick. In a 3-year study, we have adopted a herbometre similar to a rising plate meter as a reference method to obtain the weighted plant height of barley cultivars and to evaluate vehicle-based ultrasonic and laser distance sensors. Sets of 30 spring barley cultivars and 14 and 60 winter barley cultivars were tested in 2013, 2014 and 2015, respectively. The herbometre was well suited as a reference method allowing for an increased area and was easy to handle. The herbometre measurements within a plot showed very low coefficients of variation. Good and close relationships (R2 = 0.59, 0.76, 0.80) between the herbometre and the ultrasonic distance sensor measurements were observed in the years 2013, 2014 and 2015, respectively, demonstrating also increased values of heritability. Hence, both sensors were able to differentiate among barley cultivars in standard breeding trials. For the sensors, we observed a 4-fold faster operating time and 6-fold increase of measurement points compared with the herbometre measurement. Based on these results, we conclude that distance sensors represent a powerful and economical high-throughput phenotyping tool for breeders and plant scientists to estimate plant height and to differentiate cultivars for agronomic decisions and breeding activities potentially being also applicable in other small grain cereals with dense crop stands. Particularly, ultrasonic distance sensors may reflect an agronomically and physiologically relevant plant height information.

Background: Despite the excess risk of mortality in young women following acute myocardial infarction (AMI), little effort has been made to describe their long-term outcomes, particularly with respect to their health status (symptoms, function and quality of life). Accordingly, we assessed gender differences in 1-year health status outcomes after AMI. Methods: Data was used from the VIRGO study, an observational cohort of patients aged ≤55 years with AMI in the US and Spain (n=3,501, 67% women). Clinical data was abstracted from medical records and health status was obtained through patient interviews at the time of hospitalization and at 1-year later [Short Form 12 (SF-12) and the Seattle Angina Questionnaire (SAQ)]. Patient scores were categorized as “bad” if they had below average scores on the SF-12 components, had a score below 100 on the SAQ physical limitations (PL) or the SAQ angina frequency (AF), or had a score below 75 on the SAQ quality of life (QOL) at either baseline or 1-year. Patients were classified as having a “poor” outcome for a measure if they had a “bad” score at both baseline and 1-year or had a “bad” score at 1-year. Logistic regression models were used to assess factors associated with having a “poor” outcome for each scale. Results: The median age was 48 years (IQR: 44, 52). Women were more likely to present with diabetes (39% vs. 27%), obesity (51% vs. 45%), stroke (5% vs. 2%), heart failure (5% vs. 2%), lung disease (13% vs. 5%), and depression (48% vs. 24%, all P values <0.0001). Women were more likely to have “poor outcomes” compared with men (SF-12 PCS 46% vs. 30%; SF-12 MCS 47% vs. 30%; SAQ AF 32% vs. 25%; SAQ PL 29% vs. 20%; SAQ QOL 42% vs. 28%, all p-values <0.001). Female gender, prior AMI/percutaneous coronary intervention/coronary artery bypass grafting, and smoking within 30 days were independent predictors of having a “poor” outcome for all health status measures. Specifically, women had an increased odds of having a “poor” outcome on the SF-12 PCS (OR=2.05; 95% CI 1.69, 2.48), MCS (OR=1.98; 95% CI 1.65, 2.39), SAQ AF (OR=1.39; 95% CI 1.15, 1.67), SAQ PL (OR=1.62; 95% CI 1.32, 1.99) and the SAQ QOL scale (OR=1.84; 95% CI 1.53, 2.22), as compared with men. Conclusion: Compared with men, young women are more likely to have “poor” health status outcomes after AMI. This information is critically important in developing targets for gender-specific interventions to improve young women’s recovery post AMI.
