Exploring phyllosphere fungal communities of 29 alpine meadow plant species: composition, structure, function, and implications for plant fungal diseases

The phyllosphere of plants hosts diverse fungal microbial communities. Despite the significant impact of plant fungal diseases on productivity and community ecology, the relationship between phyllosphere fungal communities and plant health in natural environments remains poorly understood. This study utilized high-throughput sequencing and field investigations to explore the composition, dynamics, and incidence of fungal diseases across 29 plant species from four functional groups (forbs, grasses, legumes, and sedges) in alpine meadow plant communities of the Qinghai-Tibetan Plateau. We identified Ascomycetes and Basidiomycetes as the predominant phyllosphere fungi. Significant differences were observed in the Shannon diversity index, β-diversity, indicator fungi, and hub fungi among the functional groups. With the exception of the sedge group, the incidence of fungal diseases in other groups was positively correlated with the proportion of pathogens in the phyllosphere fungal community. Predictive analyses revealed that Ascochyta was strongly associated with high disease incidence in grasses, Cercospora in forbs, and Podosphaera in legumes, while Calophoma was associated with low disease incidence in sedges. These findings enhance our understanding of how plant phyllosphere fungal communities assemble in natural environments and improve our ability to predict and manage foliar fungal diseases in alpine meadows.

Autoimmune complications of tyrosine kinase inhibitors in cancer therapy: Clinical insights, mechanisms, and future perspectives.

The tyrosine kinase inhibitors (TKIs) have emerged as a promising class of novel anticancer drugs, achieving significant success in clinical applications. However, the risk of autoimmune diseases associated with these drugs has raised widespread concerns. In this review, TKI-induced autoimmune diseases are reviewed in order to understand this complex phenomenon through clinical research and molecular mechanism exploration. Despite the relatively low incidence of autoimmune diseases, their potential severity demands heightened attention. The potential mechanisms underlying TKI-induced autoimmune diseases may involve immune system dysregulation, alterations in immune cell function, activation of inflammatory responses, and attacks on self-antigens. Various preventive strategies, including clinical monitoring, personalized treatment, optimization of therapeutic approaches, and patient education and communication, can be employed to effectively address these potential risks. Future research directions should delve into the molecular mechanisms of TKI-induced autoimmune diseases, integrate studies on genetics and immunogenetics, advance the development of novel TKIs, explore the possibilities of combining immunotherapy with TKI treatment, and propel large-scale clinical trials.

Exploration of stable host-plant resistant sources to sterility mosaic disease of pigeonpea (Cajanus cajan L. Huth)

Sterility mosaic disease (SMD) presents a major challenge in pigeonpea cultivation throughout the Indian subcontinent. Chemical control methods, such as acaricides, are neither economically viable nor sustainable, making host plant resistance the preferred approach for managing this disease. In this study, we evaluated 45 pigeonpea germplasm accessions and breeding lines for SMD resistance over two consecutive Kharif seasons (2021-22 and 2022-23). Of the 45 genotypes tested, 8 exhibited low disease incidence (0-10%) (LRG-471, ICPL 151, ICPB 2089, ICPB 2047, ICPB 2092, ICPB 2211, ICPL 85063, and ICPL 14003) and were classified as resistant. Additionally, 23 genotypes showed disease incidence between 10.1-20.0% and were categorized as moderately resistant. These resistant genotypes offer promising new sources of SMD resistance and should be considered for inclusion in future pigeonpea breeding programs aimed at improving resistance. This research provides valuable phenotypic insights and identifies stable resistant sources essential for advancing SMD resistance breeding efforts.

Neurovirulence of Usutu virus in human fetal organotypic brain slice cultures partially resembles Zika and West Nile virus

Usutu (USUV), West Nile (WNV), and Zika virus (ZIKV) are neurotropic arthropod-borne viruses (arboviruses) that cause severe neurological disease in humans. However, USUV-associated neurological disease is rare, suggesting a block in entry to or infection of the brain. We determined the replication, cell tropism and neurovirulence of these arboviruses in human brain tissue using a well-characterized human fetal organotypic brain slice culture model. Furthermore, we assessed the efficacy of interferon-β and 2′C-methyl-cytidine, a synthetic nucleoside analogue, in restricting viral replication. All three arboviruses replicated within the brain slices, with WNV reaching the highest titers, and all primarily infected neuronal cells. USUV- and WNV-infected cells exhibited a shrunken morphology, not associated with detectable cell death. Pre-treatment with interferon-β inhibited replication of all arboviruses, while 2′C-methyl-cytidine reduced only USUV and ZIKV titers. Collectively, USUV can infect human brain tissue, showing similarities in tropism and neurovirulence as WNV and ZIKV. These data suggest that a blockade to infection of the human brain may not be the explanation for the low clinical incidence of USUV-associated neurological disease. However, USUV replicated more slowly and to lower titers than WNV, which could help to explain the reduced severity of neurological disease resulting from USUV infection.

Soybean inoculation with Azospirillum argentinense improves nodulation, grain yield, and alleviates the incidence of Fusarium at field with drought stress

ABSTRACT The efficacy of Azospirillum argentinense REC3, applied by seed inoculation, in enhancing soybean (Glycine max [L.] Merr.) nodulation with native rhizobia, improving grain yield, and protecting against Fusarium fungi was studied. In La Cruz, Tucumán, Argentina, 23 fungal isolates were identified as F. oxysporum (2 strains), F. solani (2), and F. tucumaniae (19). Following soil infestation, only F. tucumaniae was confirmed as a phytopathogen, with REC3 inhibiting its mycelial growth. Greenhouse trials, for a duration of 30 days, showed significant reductions in disease severity (78.2%), root rot (32.3%), and disease incidence (50.9%) in plants susceptible to sudden death syndrome (SDS) when REC3 was applied. Field experiments (2018–2019; January-April) under drought stress conditions, displayed increased nodulation (37.2%) and grain yield (2077 ± 272.8 kg ha−1, p < 0.05) in REC3-treated plants compared to controls (1516 ± 272.8 kg ha−1, p < 0.05). Additionally, a low disease incidence (0.90%) was observed only in the SDS-susceptible soybean variety without REC3 treatment. Overall, the findings showed the significant potential of REC3 inoculation as a biotechnological strategy for enhancing agricultural productivity, managing diseases, and improving crop resilience under challenging environmental conditions. This integrated approach, combining the use of a partially SDS-resistant soybean variety with REC3 inoculation, showed promise in protecting soybean cultivation against SDS and other fungal diseases, thereby ensuring more sustainable and resilient agricultural practices.

Comparison of Sleeve Gastrectomy with Loop Duodenojejunal Bypass Versus One Anastomosis Gastric Bypass for Type 2 Diabetes: The Role of Pylorus Preservation.

One anastomosis gastric bypass (OAGB) is recognized as a standard procedure in metabolic surgery. However, concerns about postoperative bile reflux and nutritional risks are prevalent. Comparatively, sleeve gastrectomy with loop duodenojejunal bypass (SG + LoopDJB) bypasses an equivalent length of the foregut as OAGB while maintaining pyloric function. The role of pylorus function remains to be further elucidated regarding these metabolic procedures' therapeutic outcomes and side effects. A retrospective study was conducted in our center to compare the surgical safety and 1-year outcomes of OAGB and SG + LoopDJB regarding type 2 diabetes mellitus (T2DM) remission, weight loss, gastrointestinal disorders, and nutritional status in T2DM patients matched by gender, age, and BMI. The baseline characteristics were comparable between groups. Compared with OAGB, SG + LoopDJB had longer operative time and length of stay (LOS) but similar major postoperative complications. At 1-year follow-up, OAGB has similar diabetes remission (both 91.9%), weight loss effect (28.1 ± 7.1% vs. 30.2 ± 7.0% for %TWL), and lipidemia improvement to SG + LoopDJB (P > 0.05). However, OAGB presented a higher incidence of hypoalbuminemia (11.9% vs. 2.4%, P = 0.026) but a low incidence of gastroesophageal reflux disease (GERD) symptoms (9.5% vs. 26.2%, P = 0.046) than SG + LoopDJB. There was no statistical difference regarding other gastrointestinal disorders and nutritional deficiencies between groups. Both OAGB and SG + LoopDJB show comparable, favorable outcomes in weight loss, T2DM remission, and lipidemia improvement at the 1-year follow-up. Pylorus preservation, while increasing surgical difficulty and the risk of de novo GERD, may reduce the risk of postoperative hypoalbuminemia.

Physicochemical and Nutritional Properties of Vegetable Oils from Brazil Diversity and Their Applications in the Food Industry.

In this study, the oils of açaí, passion fruit, pequi, and guava were submitted to physicochemical analysis to investigate their potential application in the food industry. Gas chromatography associated with mass spectroscopy showed that oleic and linoleic acids are mainly responsible for the nutritional quality of açaí, passion fruit, pequi, and guava oils, which exhibited 46.71%, 38.11%, 43.78%, and 35.69% of the former fatty acid, and 18.93%, 47.64%, 20.90%, and 44.72% of the latter, respectively. The atherogenicity index of the oils varied from 0.11 to 0.65, while the thrombogenicity index was 0.93 for açaí, 0.35 for guava, and 0.3 for passion fruit oils, but 1.39 for pequi oil, suggesting that the use of the first three oils may lead to a low incidence of coronary heart disease. Thermogravimetry showed that all tested oils were thermally stable above 180 °C; therefore, they can be considered resistant to cooking and frying temperatures. In general, the results of this study highlight possible applications of these oils in the food industry, either in natura or in typical food production processes.

Resistance response of yellow maize inbreds and F1 crosses against Philippine downy mildew [Peronosclerospora philippinensis (Weston) C.G. Shaw]

Maize is one of the world's most important staple crops, yet various pests and diseases impede its optimal production. Philippine maize downy mildew disease (PDM) caused by Peronosclerospora philippinensis (Weston) Shaw is one of the most devastating diseases in corn-growing areas in Asia. Breeding for resistant varieties is the most cost-effective and environmentally safe alternative for controlling the disease. In this study, we evaluated the resistance responses of yellow maize inbreds and hybrids against PDM to select promising genotypes for genetic analysis and varietal improvement. Resistance trials under greenhouse conditions were conducted to investigate the PDM resistance response of 14 selected CIMMYT lines (CMLs) and IPB Var 6 (susceptible check) to select potential parents prior to hybridization. CML 431 and CML 452 were identified to have significantly low disease incidence among the test genotypes. Subsequently, disease evaluation of the two inbred lines with putative DM resistance, four experimental hybrids derived from these inbred lines, and checks was performed in the field. Across three validation trials, inbred CML 431, and hybrid CML 452 × CML 431 showed degrees of resistance to PDM. This study's findings enabled the identification of resistant lines to downy mildew for the generation of mapping populations for genetic association studies, as well as the establishment of experimental units for transcriptomics research.

Field Performance of Sesame Varieties under Rainfed Ecosystem in Southern Tamil Nadu, India

In Pudukottai district, sesame is cultivated in 3,000 ha and farmers are predominantly growing very old sesame variety TMV 3. This variety is more susceptible to pest and diseases which leads to increased cultivation cost towards plant protection measures as well as reduced yield and income. To overcome this problem, Krishi Vigyan Kendra, Tamil Nadu Agricultural University, Pudukkottai conducted On Farm Testing (OFT) in sesame varieties for promoting the high yielding varieties. Fifteen farmers were selected in different locations of Thiruvarankulam block, Pudukkottai district in Tamil Nadu. Critical inputs of seeds of sesame varieties like TMV 7 and G.Til 10 were distributed to the farmers. The plant physiological and yield parametersviz., plant height (cm), No. of branches, No. of capsules/ branch, capsule length (cm), seeds per capsule, Yield (q/ha) and BC ratio were recorded. The results revealed that, Among the sesame varieties tested, TMV 7 was recorded the maximum plant height (125 cm), number of branches (6.6), number of capsules per plant (43.5), capsules length ( 3.3 cm), No of seeds per capsule ( 57) which resulting in the highest yield of 7.8 q/ha followed by sesame G.Til 10 which recorded more plant height (120 cm), number of branches (6.0), number of capsules per plant (38.2) capsules length ( 3.1 cm), No of seeds per capsule ( 51) and yield of 7.3 q/ha compared to farmers variety cultivating variety TMV 3 which registered the lowest plant physiological parameters and yield (6.4 q/ha). The maximum B:C ratio was recorded in sesame variety TMV 7 (3.12) followed by G.Til 10 ( 2.92) over the variety TMV 3 (2.84). From this trial, it was concluded that, farmers are satisfied with the sesame TMV 7 variety for cultivation due to its low pest and disease incidence, higher yield and BC ratio.

Evidence of Active Orbivirus Transmission in 2016 in Kansas and Nebraska.

Retrospective serological and case diagnostic data of endemic bluetongue virus (BTV) and epizootic hemorrhagic disease virus (EHDV) provide evidence of viral transmission among livestock and wildlife from 2016 in Kansas and Nebraska. Serological testing of mature cattle in nine distinct regional zones of Kansas revealed 76% to 100% had detectable antibodies to BTV and/or EHDV. Specimens tested in the Kansas Veterinary Diagnostic Laboratory (55 submissions) were 51% test positive for antibodies to BTV and/or EHDV. Specimens tested in the Nebraska Veterinary Diagnostic Center (283 submissions) were 25% test positive for antibodies to BTV and/or EHDV. Low disease incidence in white-tailed deer and other susceptible wild ungulates was observed during 2016. However, there were no confirmed reports of disease in livestock in either state. The reasons for emergence of significant clinical disease in livestock and wildlife populations remain undefined.

The bacterial and archaeal communities of flies, manure, lagoons, and troughs at a working dairy.

Fundamental investigations into the location, load, and persistence of microbes, whether beneficial or detrimental, are scarce. Many questions about the retention and survival of microbes on various surfaces, as well as the load necessary for spread, exist. To answer these questions, we must know more about where to find various microbes and in what concentrations, the composition of the microbial communities, and the extent of dissemination between various elements. This study investigated the diversity, composition, and relative abundance of the communities associated with manure, lagoons, troughs, house flies, and stable flies present at a dairy, implementing two different free-stall management systems: flow-through and cross-vent. Shotgun metagenomics at the community level was used to compare the microbiomes within the dairy, allowing confident interpretation at the species level. The results showed that there were significant difference in microbial composition between not only each of the dairy elements but also management styles. The primary exceptions were the microbiomes of the house fly and the stable fly. Their compositions heavily overlapped with one another, but interestingly, not with the other components sampled. Additionally, both species of flies carried more pathogens than the other elements of the dairy, indicating that they may not share these organisms with the other components, or that the environments offered by the other components are unsatisfactory for the survival of some pathogens.. The lack of overlapping pathogen profiles suggests a lack of transfer from flies to other dairy elements. Dairy health data, showing a low incidence of disease, suggests minimal sharing of bacteria by the flies at a level required for infection, given the health program of this dairy. While flies did carry a multitude of pathogenic bacteria, the mere presence of the bacteria associated with the flies did not necessarily translate into high risk leading to morbidity and mortality at this dairy. Thus, using flies as the sole sentinel of dairy health may not be appropriate for all bacterial pathogens or dairies.

Metagenomic exploration of the rhizosphere soil microbial community and their significance in facilitating the development of wild-simulated ginseng.

Panax ginseng, a prized medicinal herb, has faced increasingly challenging field production due to soil degradation and fungal diseases in Northeast China. Wild-simulated cultivation has prevailed because of its sustainable soil management and low disease incidence. Despite the recognized benefits of rhizosphere microorganisms in ginseng cultivation, their genomic and functional diversity remain largely unexplored. In this work, we utilized shotgun metagenomic analysis to reveal that Pseudomonadota, Actinomycetota, and Acidobacteriota were dominant in the ginseng rhizobiome and recovered 14 reliable metagenome-assembled genomes. Functional analysis indicated an enrichment of denitrification-associated genes, potentially contributing to the observed decline in soil fertility, while genes associated with aromatic carbon degradation may be linked to allelochemical degradation. Further analysis demonstrated enrichment of Actinomycetota in 9-year-old wild-simulated ginseng (WSG), suggesting the need for targeted isolation of Actinomycetota bacteria. Among these, at least three different actinomycete strains were found to play a crucial role in fungal disease resistance, with Streptomyces spp. WY144 standing out for its production of actinomycin natural products active against the pathogenic fungus Ilyonectria robusta. These findings not only enhance our understanding of the rhizobiome of WSG but also present promising avenues for combating detrimental fungal pathogens, underscoring the importance of ginseng in both medicinal and agricultural contexts.IMPORTANCEWild-simulated ginseng, growing naturally without human interference, is influenced by its soil microbiome. Using shotgun metagenomics, we analyzed the rhizospheric soil microbiome of 7- and 9-year-old wild-simulated ginseng. The study aimed to reveal its composition and functions, exploring the microbiome's key roles in ginseng growth. Enrichment analysis identified Streptomycetes in ginseng soil, with three strains inhibiting plant pathogenic fungi. Notably, one strain produced actinomycins, suppressing the ginseng pathogenic fungus Ilyonectria robusta. This research accelerates microbiome application in wild-simulated ginseng cultivation, offering insights into pathogen protection and supporting microbiome utilization in agriculture.

Molecular characterization of Rice ragged stunt virus and Rice grassy stunt virus on Rice in Gianyar, Bali, Indonesia

Rice stunt disease is one of the causes of rice harvest failure. It is caused by the infection of Rice ragged stunt virus (RRSV) and Rice grassy stunt virus (RGSV) infection. Information about disease severity and the molecular characteristics of stunt viruses in Indonesia is still limited. Thus, this research aimed to determine the disease severity and the genetic diversity of rice stunt viruses in Gianyar, Bali. The research method consisted of observation of incidence and disease severity in the field and virus detection by reverse transcription-polymerase chain reaction (RT-PCR) using primers specific for RRSV and RGSV. The observation of the disease incidence and severity were performed in seven districts in Gianyar Regency, Bali, namely Blahbatuh, Gianyar, Payangan, Sukawati, Tampaksiring, Tegallalang, and Ubud. Stunt disease was found in all observation sites. High stunt disease incidence (&gt; 44%) was found in three districts: Ubud, Tampaksiring, and Payangan, while the low disease incidence rate of &lt;10% was found in Blahbatuh and Gianyar Districts. The highest stunt disease severity occurred in Tampaksiring District (60.82%), while the lowest severity occurred in Gianyar District (18.84%). The IR-64 and Ciherang cultivars are vulnerable to rice stunt disease infection. The highest homology of RRSV and RRGV nucleotides was found with Vietnam isolates being &gt;98% and &gt;97%, respectively. The phylogenetic analysis showed that Indonesian isolates of RRSV and RGSV were clustered in the same group as Vietnam isolates.

First Report of Geotrichum candidum Causing Rubbery Rot on Potato in Arizona.

In January 2023, stand loss due to seed decay (<3% incidence) was reported in a commercial seed potato field in Cochise County, Arizona. Several rotted 'Ciklamen' tubers with wilting shoots were submitted to the University of Arizona Extension Plant Pathology Laboratory for diagnosis. External symptoms included sunken black-colored lesions on affected tubers; white fungal-like growth was also present on the surface of the more severely affected tubers. Internal tissues were watery, rubbery-textured, and spongy with slight gray discoloration. Isolation from the necrotic tubers on PDA yielded yeast-like fungal colonies. Two derived fungal isolates were subcultured on PDA at room temperature for three days, and colonies had a white, dense, and creamy appearance. Hyphae were hyaline, septate, dichotomously branched, and broken into chains of cylindrical to oval-shaped, single-celled arthrospores ranging in size from 3.8-5.3 μm × 5.4-12.5 μm (n = 20). These morphological characteristics matched those of Geotrichum candidum (Carmichael, 1957). Other common potato pathogens, including Pythium, Phytophthora, and Fusarium, were not detected in the samples. For molecular identification, genomic DNA was extracted from the mycelia of two isolates using the DNeasy Plant Pro Kit (Qiagen Inc., Valencia, CA) according to the manufacturer's instructions. Partial DNA sequences of the internal transcribed spacer (ITS) region of rDNA and elongation factor 1-alpha (EF-1α) gene were amplified and sequenced using primers ITS1/ITS4 (White et al., 1990), EF1-728F/EF1-1567R (Carbone and Kohn 1999) and EF1-1018/EF1-1620R (Stielow et al., 2015). The resulting sequences showed no difference between the isolates and were deposited under the GenBank Accession Numbers OQ690039 and OQ981192. Based on BLASTn analysis, ITS sequence OQ690039 (369-bp) had a 99.46% match with Geotrichum candidum accessions MN861070 and KY103456. EF-1α sequence OQ981192 (843-bp) showed 100% identity with G. candidum accessions MT346368 of the G. candidum isolates responsible for sour rot of strawberries in Florida (Alonzo et al., 2020). A pathogenicity test was conducted twice on ten healthy 'Ciklamen' tubers, surface sterilized using 10% sodium hypochlorite solution, and rinsed copiously in sterilized water. A conidial suspension (106 conidia/ml) of the isolated fungus was sprayed onto the surface of the tubers. The control consisted of ten tubers that were mock-sprayed with sterilized water. All tubers were incubated in separate sterilized plastic bags in the dark at room temperature for four weeks and examined daily for symptom development. Symptoms of rubbery texture and fluid leaking when cut, and a distinctive smell, were produced on the inoculated tubers. In contrast, the controls did not show any symptoms. These symptoms were similar to those observed on naturally infected tubers. The fungus was re-isolated from symptomatic tissues of inoculated tubers and identified by PCR as G. candidum, thus fulfilling Koch's postulates. To our knowledge, this is the first report of G. candidum as a potato pathogen in Arizona. Rubbery rot of potatoes by G. candidum has been reported previously in Idaho (Duellman et al., 2020) and Michigan (Willbur et al., 2021). Arizona annually grows approximately 1,000 hectares of seed potatoes shipped to various states. Therefore, growers must obtain a correct diagnosis to avoid spreading the disease despite the low incidence of disease.

Socio-Demographic and Eco-Epidemiological Parameters of Tick-Borne Infections Morbidity in Baikal Region

The aim of the work was to compare the main socio-demographic and eco-epidemiological parameters of tick-borne viral encephalitis, tick-borne borrelioses and tick-borne rickettsiosis.Materials and methods. The authors’ databases based on epidemiological investigation records were used for the study. All in all, 2974 cases (Irkutsk and the Irkutsk district) were analyzed during the periods of 1995–2022 for tick-borne viral encephalitis and tick-borne borrelioses, and 2001–2022 for tick-borne rickettsiosis.Results and discussion. The following parameters were assessed: the timing of epidemic season; the geography of prevalence; localization of tick bite on the human body; incubation time; gender and age structure of patients; social composition and exposure conditions. It was shown, that the parameters had their own features for each disease, and part of them are common to all Eurasian area of these infections. The shared characteristics include: the early epidemic season onset for tick-borne rickettsiosis; the shorter incubation time for tickborne rickettsiosis as compared to tick-borne viral encephalitis and tick-borne borrelioses; the increased frequency of tick-borne rickettsiosis vectors’ bites near the head and neck, and tick-borne borrelioses vectors – on the torso; large percentage of older persons among patients with tick-borne borrelioses and children under 14 years of age among patients with tick-borne rickettsiosis; prevalence of male population over female one as regards all surveyed pathogens. Low incidence of tick-borne diseases among professional contingent (the work associated with staying in natural foci of infection), an increased risk of tick-borne encephalitis and rickettsiosis among social group “unemployed”, and tick-borne borrelioses – among retirees, can be attributed to regional specificity.

Особенности заболеваемости детей болезнями костно-мышечной системы и соединительной ткани в Чеченской республике.

Pathology of the musculoskeletal system is of great medical and social importance and is one of the ten most common diseases. The high prevalence of diseases is due to a variety of risk factors. Polyethics, Cultural, Territorial and Demographic Features of the Chechen Republic (high birth rate, high proportion of the child population, predominance of rural residents, shortage of medical personnel), are reflected in the specifics of the provision of medical care to the population, and the analysis of the incidence of diseases of the musculoskeletal system and connective tissue in children is of interest and the need for detailed consideration. The purpose of the study: to determine the peculiarities of primary and general morbidity of diseases of the musculoskeletal system and connective tissue in children in the Chechen Republic. Materials and methods. Primary and general morbidity rates of children with musculoskeletal and connective tissue diseases were assessed and analyzed according to official statistical reports and publications of the Federal State Statistics Service and the Ministry of Health of Russia for the Chechen Republic in dynamics for 2016–2022. Statistical processing was performed in MS Office‑2016 program (Word, Excel). Results. The study showed a low incidence of musculoskeletal and connective tissue diseases in children in the Chechen Republic. The incidence of children in the groups of 0–14 and 15–17 years for the last 7 years has generally had a decreasing dynamics, with a change of trend: a decrease in 2016–2019 and an increase in cases of most nosologies in 2020–2022. Against the background of the COVID‑19 pandemic, there was a significant increase in deforming dorsopathies and arthropathies in general, including reactive arthropathies and juvenile arthritis. At the same time, no such correlation was found in rheumatoid arthritis: against the background of the pandemic, the downward trend in the registration of cases was continued. Conclusions. When organizing medical care for children with diseases of the musculoskeletal system and connective tissue, the prevalence of pathology, the level of medical staffing and the age composition of the child population should be taken into account. During 2016–2022, a decrease in primary morbidity prevailed in children 0–14 years of age, and in adolescents – in total morbidity. The COVID‑19 pandemic (the virus itself, decreased physical activity, and conditions limiting the availability of ambulatory care) contributed to the increase in most arthropathies and deforming dorsopathies. On the contrary, the incidence of rheumatoid arthritis in children has been steadily decreasing for 7 years.

Multi-environment evaluation of rice genotypes: impact of weather and culm biochemical parameters against sheath blight infection.

Sheath blight caused by Rhizoctonia solani is one of the major diseases of rice, causing widespread crop losses. The use of semi-dwarf rice varieties in the ongoing nutrient-intensive rice cultivation system has further accentuated the incidence of the disease. An ideal solution to this problem would be identifying a stable sheath blight-tolerant genotype. A multi-environment evaluation of 32 rice genotypes against sheath blight infection was conducted over six seasons across two locations (Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University (28.18° N, 38.03° E, and 75.5 masl), for four years during the wet seasons (kharif) from 2015 to 2018 and two seasons at the National Rice Research Institute (20°27'09" N, 85°55'57" E, 26 masl), Cuttack, Odisha, during the dry season (rabi) of 2019 and the kharif of 2019, including susceptible and resistant check. Percent disease index data were collected over 4 weeks (on the 7th, 14th, 21st, and 28th day after infection), along with data on other morphological and physiological traits. The resistant genotypes across seasons were the ones with a higher hemicellulose content (13.93-14.64) and lower nitrogen content (1.10- 1.31) compared with the susceptible check Tapaswini (G32) (hemicellulose 12.96, nitrogen 1.38), which might explain the resistant reaction. Three different stability models-additive main effect and multiplicative interaction (AMMI), genotype + genotype x environment (GGE) biplot, and multi-trait stability index (MTSI)-were then used to identify the stable resistant genotypes across six seasons. The results obtained with all three models had common genotypes highlighted as stable and having a low area under the disease progress curve (AUDPC) values. The ideal stable genotypes with low disease incidence were IC 283139 (G19), Tetep (G28), IC 260917 (G4), and IC 277274 (G10), with AUDPC values of 658.91, 607.46, 479.69, and 547.94, respectively. Weather parameters such as temperature, rainfall, sunshine hours, and relative humidity were also noted daily. Relative humidity was positively correlated with the percent disease index.

The epidemiology of fecal carriage of nontyphoidal Salmonella among healthy children and adults in three sites in Kenya.

Despite the importance of non-Typhoidal Salmonella (NTS) disease in Africa, epidemiologic data on carriage and transmission are few. These data are important to understand the transmission of NTS in Africa and to design control strategies. To estimate the prevalence of stool carriage of NTS in Kenya, we conducted a cross-sectional study in Kilifi, Nairobi, and Siaya, sites with a low, moderate and high incidence of invasive NTS disease, respectively. At each site, we randomly selected 100 participants in each age-group of 0-11 months, 12-59 months, 5-14 years, 15-54 years and ≥55 years. We collected stool, venous blood (for hemoglobin and malaria rapid tests), anthropometric measurements, and administered a questionnaire on Water Access Sanitation and Hygiene (WASH) practices. Stool samples were cultured on selective agar for Salmonella; suspect isolates underwent serotyping and antimicrobial susceptibility testing. Overall, 53 (3.5%) isolates of NTS were cultured from 1497 samples. Age-adjusted prevalence was 13.1% (95%CI 8.8-17.4) in Kilifi, 0.4% (95%CI 0-1.3) in Nairobi, and 0.9% (95%CI 0-2.0) in Siaya. Prevalence was highest among those aged 15-54 years (6.2%). Of 53 isolates; 5 were S. Enteritidis, 1 was S. Typhimurium. No S. Typhi was isolated. None of the risk factors were associated with carriage of NTS. All isolates were susceptible to all antibiotics tested, including ampicillin, chloramphenicol, ciprofloxacin and co-trimoxazole. Prevalence of fecal carriage was high in Kilifi, an area of low incidence of invasive NTS disease and was low in areas of higher incidence in Nairobi and Siaya. The age-prevalence, risk factors, geographical and serotype distribution of NTS in carriage differs from invasive disease.

Health statistics indicators as a factor in accounting for occupational morbidity

Introduction When analyzing the risk of the impact of harmful factors on the health of employees, some researchers explain the low incidence of occupational diseases in Russia by errors in their detection during preventive examinations, lack of interest of employers and employees in the detection and registration of these diseases, and other reasons. At the same time, we did not find any works in the literature devoted to errors in coding of diagnoses of occupational diseases and their registration.The purpose of the work is to identify the cause of poor accounting of occupational diseases in Russia.Materials and methods The work was carried out on the basis of the Industrial Register of persons with occupational diseases. The registry was developed by the A.I. Burnazyan Federal Medical and Biological Center and has been in commercial operation since 2011. As of 31.12.2020, the register contains information about 2 300 patients with occupational diseases from among the employees of enterprises and organizations served by the health care institutions of FMBA of Russia. Directive documents on identification and registration of occupational diseases were analyzed.Results and discussion Analysis of the health of the working contingent and the subsequent creation of plans for medical and rehabilitation measures to reduce the incidence of occupational diseases among persons working at enterprises and organizations that are on dispensary registration in health care institutions of FMBA of Russia, requires knowledge of correct morbidity indicators about them. For this purpose, it is necessary to improve the registration of occupational diseases in Russia by switching to the diagnosis coding system adopted in the country’s sanitary statistics, and to make appropriate changes in policy documents.Conclusion One of the reasons for errors in recording occupational diseases is the violation of classification principles in the Order of the Ministry of Health and Social Development of Russia No 417n.

Decoding the Polyphenol Impact on the Cardiovascular System: A Journey from the French Paradox to Restenosis

&#x0D; Resveratrol and quercetin, two natural polyphenolic compounds, exhibit potential in veterinary and human medicine for cardiovascular benefits, particularly for the prevention and management of restenosis, a complex process involving blood vessel re-narrowing. This review investigates the impact of these compounds on restenosis in animal models, explaining their modes of action, which include antioxidant, anti-inflammatory, and anti-proliferative capabilities. Additional insights are provided by the intriguing "French Paradox," in which the Southern French population's low heart disease incidence is associated with red wine and polyphenol-rich diet consumption. Through animal models, we gain essential knowledge about the therapeutic potential, safety, and dosing of resveratrol and quercetin in both veterinary and human clinical settings. Understanding their precise molecular pathways is essential in enhancing their effectiveness in reducing restenosis. The "French Paradox" draws attention to the potential cardiovascular benefits of polyphenols in restenosis. Novel approaches to minimize restenosis in veterinary and human medicine may result from bridging the gap between animal models and human trials.&#x0D;
