Public health impact and return on investment of the pediatric National Immunization Program in Italy

ABSTRACT Objectives We conducted a cost–benefit analysis of the pediatric National Immunization Program (NIP) in Italy. Methods An economic model evaluated the benefit–cost ratio (BCR) of the Italian pediatric NIP, including 10 pathogens for mandatory vaccines and 4 pathogens for recommended vaccines for children aged 0–10 years from the healthcare-sector and societal perspectives. Separate decision trees were used to model each vaccine-preventable disease (VPD). The 2020 birth cohort (n = 420,084) was followed over their lifetime; the model projected and compared discounted disease cases, life-years, quality-adjusted life-years (QALYs), and costs (2021 euros) with and without immunization (based on current and pre – vaccine era disease incidence estimates, respectively). Results The pediatric NIP was estimated to prevent 1.8 million cases of VPDs and 3,330 deaths, resulting in 45,900 fewer life-years lost and 57,000 fewer QALYs lost. Vaccination costs of €285 million were offset by disease cost savings of €1.6 billion, resulting in a BCR of 5.6 from a societal perspective (BCR = 1.7 from a healthcare-sector perspective). When QALYs gained were valued, the BCR increased to 15.6. Conclusions The benefits of the Italian pediatric NIP, including averted disease-related morbidity, mortality, and associated costs, highlight the value of continued investment in pediatric immunization.

Interferon regulatory factor 7 alleviates the experimental colitis through enhancing IL-28A-mediated intestinal epithelial integrity

BackgroundThe incidence of inflammatory bowel disease (IBD) is on the rise in developing countries, and investigating the underlying mechanisms of IBD is essential for the development of targeted therapeutic interventions. Interferon regulatory factor 7 (IRF7) is known to exert pro-inflammatory effects in various autoimmune diseases, yet its precise role in the development of colitis remains unclear.MethodsWe analyzed the clinical significance of IRF7 in ulcerative colitis (UC) by searching RNA-Seq databases and collecting tissue samples from clinical UC patients. And, we performed dextran sodium sulfate (DSS)-induced colitis modeling using WT and Irf7−/− mice to explore the mechanism of IRF7 action on colitis.ResultsIn this study, we found that IRF7 expression is significantly reduced in patients with UC, and also demonstrated that Irf7−/− mice display heightened susceptibility to DSS-induced colitis, accompanied by elevated levels of colonic and serum pro-inflammatory cytokines, suggesting that IRF7 is able to inhibit colitis. This increased susceptibility is linked to compromised intestinal barrier integrity and impaired expression of key molecules, including Muc2, E-cadherin, β-catenin, Occludin, and Interleukin-28A (IL-28A), a member of type III interferon (IFN-III), but independent of the deficiency of classic type I interferon (IFN-I) and type II interferon (IFN-II). The stimulation of intestinal epithelial cells by recombinant IL-28A augments the expression of Muc2, E-cadherin, β-catenin, and Occludin. The recombinant IL-28A protein in mice counteracts the heightened susceptibility of Irf7−/− mice to colitis induced by DSS, while also elevating the expression of Muc2, E-cadherin, β-catenin, and Occludin, thereby promoting the integrity of the intestinal barrier.ConclusionThese findings underscore the pivotal role of IRF7 in preserving intestinal homeostasis and forestalling the onset of colitis.

Detection and Characterization of Lasiodiplodia pseudotheobromae Associated with Stem Wilt on Ficus hirta (Vahl) and Its Fungicidal Sensitivity

Ficus hirta Vahl is an important medicinal and edible plant in southern China. Typical green wilting on leaves and brown necrotic spots on the stems were observed since mid-June 2022 in an F. hirta plantation in Danzhou, Hainan (China). The disease rapidly developed, causing stem withering and plant death. The disease incidence varied from 45 to 85% prevalence, and the average disease index was 47 in the period of outbreak during June to December. Relevant hypothetical fungi were isolated from naturally infected wilt tissues, and their pathogens were preliminarily confirmed to be Lasiodiplodia pseudotheobromae through hypothetical fungal culturing, morphological characteristic observations, and pathogenicity testing on F. hirta plants. The phylogenetic tree constructed based on partial ITS, translation elongation factor (TEF1-α), and the β-tubulin gene (TUB2) further confirmed the identity of the pathogen as L. pseudotheobromae. Further research on the biological characteristics of L. pseudotheobromae showed that the optimal temperature for the growth of L. pseudotheobromae was PDA medium, with a temperature of 30 °C and pH of 6. Peptone and fructose were the optimal nitrogen and carbon sources for it. In vitro efficacy testing showed that among eleven fungicides, fluazinam and prochloraz had the highest mycelial growth inhibition, with an EC50 of 0.0477 µg/mL and 0.0996 µg/mL, respectively. And the two fungicides showed significant control on the stem wilt of F. hirta in a pot. To our knowledge, this is the first comprehensive report on the pathogen identification and biological characteristics of L. pseudotheobromae infecting the stem wilt of F. hirta in China. Our results provide important information for developing effective management measures and controlling this disease.

Helicobacter pylori and Its Treatment Impact on Immune-Mediated Ocular Diseases

ABSTRACT Purpose Helicobacter pylori (HP), which colonizes exclusively in the gastrointestinal tract, has been reported to dysregulate the immune response and gives rise to several extra-gastrointestinal autoimmune disorders. However, the relationship between HP and immune-mediated ocular diseases remains ambiguous. This study aims to clarify the association between immune-mediated ocular diseases and HP infection, as well as the impact of HP treatment on the incidence of immune-mediated ocular diseases. Methods This is a retrospective population-based study using National Health Insurance Research Database in Taiwan. Patients with newly diagnosed peptic ulcer disease or HP infection between 2009 and 2015 were identified as HP group and compared to the non-HP group with one-to-one exact matching. Moreover, the incident risk of immune-mediated ocular diseases and its two subgroups (ocular surface and orbital inflammation group, intraocular inflammation group) were compared in HP patients with or without treatment. Results A total of 1,030,119 subjects in the non-HP group and 1,030,119 patients in the HP group were enrolled. The incidence rate of immune-mediated ocular diseases was significantly higher in the HP group (95% confidence interval (CI): 2.534–2.547). The incident rate ratio was significantly higher in HP with treatment than without treatment (HR: 1.654, 95% CI: 1.641–1.668). The Cox proportional hazards regression model demonstrated a significantly increased HR of immune-mediated ocular diseases in HP treated group (HR: 2.265, 95% CI: 2.024–2.534) and less increased HR in HP non-treated group (HR: 1.427, 95% CI: 1.273–1.598) when comparing to non-HP group. Subgroup analysis demonstrated a significantly higher incidence rate of ocular surface and orbital inflammation as well as intraocular inflammation in the HP group. Conclusion This study illustrated a higher incidence of immune-mediated ocular diseases in HP infection, and a heightened risk following HP eradication.

Exploring the gap between notified and diagnosed cases of Food-borne Diseases: evidence from a time-trend analysis in Italy.

Foodborne diseases are a major global public health concern, causing significant morbidity and mortality worldwide. The COVID-19 pandemic has had widespread effects on various aspects of life, including the food supply chain, potentially impacting the incidence of foodborne diseases. This study aims to analyze the differences between notified and diagnosed cases and investigate the potential impact of the COVID-19 pandemic on foodborne diseases in the metropolitan area of Bologna, Italy. A retrospective time trend analysis from two databases was conducted. The Local Health Authority of Bologna collected data re/Emilia-Romagna Region on the infectious disease reporting system over a six-year period (2017-2022), which included three years of the COVID-19 pandemic. This data was compared with information collected during the same period at the microbiology laboratory serving the entire metropolitan area of Bologna. Statistical methods included percent change calculations, binomial tests, annual averages, gender and age stratification, and trend analysis with regression. An increase (+34.4%, P-value ≤ 0.01) in notified cases during the pandemic - compared to the pre-pandemic period - was found. However, no differences were observed in diagnosed cases when comparing the two periods. The year 2021 saw a significant increase in reported cases of foodborne diseases among schoolers (+300.0%) and workers (+133.3%) compared to 2020. On the other hand, diagnosed cases decreased significantly in 2020 (-19.1%, P<0.01) and increased in 2021 (+21.9%, P<0.01). In absolute terms, a stark difference was observed between notified and diagnosed cases across all the study years (2017-2022). This study highlights the discrepancy between notified and diagnosed cases of foodborne diseases and how the COVID-19 pandemic has increased reporting without affecting transmission. These findings contribute to the ongoing discussion on improving foodborne disease reporting systems.

Targeting RAC1 might be a potential therapeutic strategy for diabetic kidney disease: a Mendelian randomization study.

This study aimed to ascertain the causal association between Ras-related C3 botulinum toxin substrate 1 (RAC1) and the incidence and progression of diabetic kidney disease (DKD) through Mendelian randomization analysis. RAC1 expression, evaluated using expression quantitative trait loci data from the eQTLGen Consortium, was served as the exposure variable. Outcomes encompassed the risk of DKD, end-stage renal disease (ESRD), albuminuria assessed by the urinary albumin-to-creatinine ratio (ACR), and estimated glomerular filtration rate (eGFR) among individuals with diabetes. Causal associations were computed using the inverse variance weighted (IVW), weighted median, and MR-PRESSO models. Additionally, we conducted analyses for heterogeneity, horizontal pleiotropy, and sensitivity. This study revealed a causal association between the genetic activation of RAC1 and an elevated risk of DKD among individuals with diabetes [IVW, odds ratio (OR) = 1.28, 95% confidence intervals (CI) 1.08-1.51, P = 0.004]. Furthermore, increased expression of RAC1 was linked to a higher risk of ESRD (IVW, OR = 1.20, 95% CI 1.02-1.43, P = 0.032). Excessive RAC1 expression was causally associated with elevated ACR (IVW, β = 0.052, 95% CI 0.003-0.100, P = 0.036). However, the analysis regarding RAC1 and eGFR showed significant heterogeneity and pleiotropy, with no discernible causal relationship. These findings suggested a positive correlation between the genetic activation of RAC1 and the incidence of DKD, the risk of ESRD, and exacerbated albuminuria among individuals with diabetes. Targeting RAC1 might potentially serve as a therapeutic strategy for DKD.

7045 A Rare Case of Lyme-Associated Thyroiditis in an Otherwise Healthy Patient

Abstract Disclosure: M. Windham: None. S.K. Majumdar: None. Introduction: Lyme disease, a common tick-borne illness, causes multiorgan inflammation and dysfunction. It commonly affects the musculoskeletal, neurologic, cardiovascular, and integumentary systems. The endocrine system is rarely involved. We report a case of Lyme-associated thyroiditis in an otherwise healthy 41-year-old man. Case: A 41-year-old man with a history of hypertension, gastroesophageal reflux and a known BRCA2 mutation presented to the emergency department due to one week of frequent palpitations, fatigue, dyspnea on exertion, and dry cough. Laboratory testing revealed thyrotoxicosis with an undetectable TSH (n 0.270—4.200 µIU/mL), FT4 of 7.04 ng/dL (n 0.80—1.70 ng/dL), and TT3 of 253 ng/dL (n 92.0—224 ng/dL). He denied any recent illnesses or pain in his thyroid. Further work up revealed negative TSI and TPO but did show an elevated high sensitivity CRP of 4.3 mg/L (n &amp;lt;1.0 mg/L) and a sedimentation rate of 33 mm/hr (n 0—20 mm/hr). A thyroid uptake and scan showed markedly decreased uptake suggestive of thyroiditis. The patient was started on a prednisone taper with improvement in his TFTs. At his follow up visit approximately one month later, he reported increasing stiffness in his bilateral jaw and continuing palpitations with movement despite near normalization in his FT4 and TT3, suggestive of possible underlying cardiac conduction defects. He did not recall a tick bite but lived in an area with endemic Lyme disease. Lyme antibodies were sent and returned with a positive Lyme IgG and an indeterminate Lyme IgM, which would be consistent with an active Lyme disease infection at the time of his initial presentation. Treatment for Lyme disease was prescribed. Conclusion: Between 1991 and 2021, the incidence of Lyme disease in the United States doubled due to the combined effects of climate change, increasing host species populations, and human encroachment on animal habitats. People who live in areas with endemic Lyme disease, such as the Northeast and upper Midwest regions of the United States, are at risk even if they do not recall a specific exposure. Although Lyme thyroiditis is extremely rare, its incidence is expected to increase as the overall incidence of Lyme disease increases. Therefore, it is important to consider Lyme disease in the differential when a patient from an endemic area presents with unexplained thyroiditis. Presentation: 6/2/2024

Identification of common spatial and temporal trends in the epidemiology of cattle bovine tuberculosis and human extrapulmonary and drug-resistant tuberculosis in Malawi

BackgroundIdentification of common spatial disease trends between cattle bovine tuberculosis (BTB) and human extrapulmonary tuberculosis (EPTB) and drug-resistant tuberculosis (DRTB) can support integrated disease control and monitoring programmes. We employed the recently developed multivariate disease mapping methods to examine whether the diseases exhibited any spatial correlation. MethodsA retrospective study of cattle BTB and human EPTB and DRTB cases from 2018 to 2022 was conducted. Bivariate shared spatiotemporal components models were fitted to a) cattle BTB and human EPTB and b) cattle BTB and human DRTB at the district level in Malawi, with cattle density, human density and climatic variables as independent variables. ResultsDisease specific spatial effects were higher in the southern half of the country, while the shared spatial effects were more dominant in both the south and western parts of the country. The shared temporal effects showed constant trends, while disease specific temporal effects showed an increasing pattern for cattle BTB and a constant pattern for human EPTB and DRTB. The predicted disease incidence pattern for all forms of TB in the period without data showed a constant pattern over the years. Cattle density was positively associated with cattle BTB (β: 0.022; 95% Credible Interval (CI): 0.004, 0.042). Human density was positively associated with human EPTB (β: 0.005; 95% CI: 0.001, 0.009). ConclusionCattle BTB and human EPTB and DRTB have a common spatial pattern in the west and southern parts of Malawi. Integrated interventions targeting high-density areas for cattle and human may have positive impacts on cattle BTB and human EPTB and DRTB.

The biosynthesis of ZnO nanoparticles using Synadenium grantii latex: characterization and evaluation of their antimicrobial activities

The steadily rising incidences of microbial and infectious diseases pose a direct threat to both human and animal sustainability. Over the previous 20 years, the expectations for eco-friendly nanoparticles application as contemporary medicinal agents have grown. This is why, as opposed to using hazardous chemicals, researchers have recently concentrated on simple, green, sustainable, and affordable ways to create nanoparticles. This research aimed to use the latex of Synadenium grantii to synthesize ZnO NPs (zinc oxide nanoparticles) using a simple and environmentally friendly technique. The observation of the maximum wavelength at 365 nm using Ultraviolet-visible (UV-Vis) spectrometry signified the formation of zinc oxide nanoparticles. The FT-IR (Fourier transform-infrared) spectrometry indicated the bands of various biomolecules (mainly polyphenols at 1541 cm-1 wavenumber) involved in reducing and capping zinc oxide nanoparticles. The XRD spectrum demonstrated the wurtzite phases of ZnO nanoparticles of 24 nm in size. The synthesized ZnO NPs demonstrated great anti-microbial potency compared to the positive control (ampicillin) as tested on Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). The study confirmed the presence of various chemical compounds in latex of Synadenium grantii responsible for the synthesis of ZnO NPs with enhanced anti-bacterial effects in comparison to the latex extract.

Transportation noise and cardiovascular health: an Umbrella+ review

A significant number of studies have shown an association between transportation noise and cardiovascular diseases. With this Umbrella+ review, we aimed to provide a comprehensive overview of the literature on the relation between transportation noise and various cardiovascular health outcomes such as ischaemic heart disease, stroke, heart failure, blood pressure and hypertension, as well as cardiovascular mortality. Following the Umbrella+ approach, we first identified the newest review of high quality and then original high-quality studies published thereafter. Further, by including the latest studies we performed a meta-analysis to derive up-to-date exposure-response functions for each noise source (road traffic, railway and aircraft) separately. We found that compared to road traffic noise, less research was available for railway and aircraft noise. Regarding road traffic noise, we identified a significantly increased risk for multiple cardiovascular health outcomes. For example, the pooled effect estimate for cardiovascular mortality was 1.05 (95% CI: 1.02-1.07) per 10dB(A) increase in noise, for the incidence of ischaemic heart disease it was 1.04 (95% CI: 1.02-1.06) and for stroke incidence 1.05 (95% CI: 1.01-1.08) per 10dB(A) increase in noise. This work will be used to quantify the burden of disease from transportation noise for the general population in Europe.

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.

Self-testing strategy to eliminate Hepatitis C as per WHO's goal: Analysis of disease burden and cost-effectiveness.

The World Health Organization (WHO) aims to eliminate hepatitis C Virus (HCV) by 2030, therefore, widespread HCV screening is required. The WHO recommends HCV self-testing (HCVST) as a new approach. We aimed to evaluate disease burden reduction using the HCVST screening strategy and identify the most cost-effective approach. We developed a dynamic open-cohort Markov model to assess the long-term effects and cost-effectiveness of HCVST in the Republic of Korea from 2024 to 2030. Strategies for comparison included universal, birth cohort, high-risk group screening, and no screening, focusing on the following: (1) incremental cost-effectiveness ratio (ICER) per disability-adjusted life-year (DALY) saved; (2) severe liver disease cases; and (3) liver-related death reduction. Universal HCVST screening is the most effective strategy for achieving the WHO goal by 2030, substantially lowering the incidence of severe liver disease by 71% and preventing liver-related deaths by 69 %, thereby averting 267,942 DALYs. Moreover, with an ICER of $8,078 per DALY and high cost-effectiveness, the sensitivity results prove that cost-effectiveness is robust. Although high-risk group screening offers the lowest cost compared with other strategies, its effectiveness in preventing severe liver disease is minimal, falling short of the current WHO goal. Our study confirms that universal HCVST screening is a cost-effective strategy aligned with the WHO goal to eliminate HCV by 2030. Despite its higher costs compared to risk-based screening, the disease burden can be significantly reduced by providing effective HCVST access to individuals who might otherwise not be tested.

Strategic Infectious Diseases in Beef Cattle in Balongpanggang during 2023

Strategic infectious animal diseases have a great impact on the national economy as they may cause great economic loss, public anxiety, and high mortality. In Indonesia, among the diseases considered as strategic infectious animal diseases is foot and mouth disease (FMD). This study reported the incidence of strategic infectious animal diseases in Balongpanggang district during 2023. Throughout 2023, FMD only accounted for 4% of the total diseases of the year and was the only strategic infectious animal disease reported that year. Meanwhile, bovine ephemeral fever (BEF) incidence reached 57% (876/1546) of the total diseases in beef cattle in 2023. In addition to BEF, official veterinary services reported a total case of 1546 throughout 2023 that comprises; diarrhea (99), limping (24), helminthiasis (91), ectoparasite (11), hematochezia (3), wound (3), mastitis (4), allergy (1), dystocia (28), vaginal prolapse (11), dermatitis (45), enteritis (27), tympani (11), scabiosis (122), arthritis (67), ophthalmic problem (11), endometritis (1), uterine retention (13), indigestion (2), pneumonia (21), hypoglycemia (5), abscess (21), ovariohysterectomy (1), orchitis (1), intoxication (1), and papilloma (1). In conclusion, the only strategic infectious animal disease reported in 2023 in Balongpanggang was FMD with the incidence as high as 3% as compared to the non-strategic infectious animal diseases, BEF, which reached 54% of the total cases during 2023.

The relationship between HIV/AIDS and coronary heart disease: A bibliometric analysis.

Acquired immunodeficiency syndrome is a malignant infectious disease caused by the human immunodeficiency virus (HIV). HIV gradually destroys the body's immune system and weakens the body's ability to resist diseases. People living with HIV may have a higher incidence of coronary heart disease than people without HIV. A literature retrieval from January 1, 1993 to October 1, 2023 based on the Web of Science Core Collection database. CiteSpace6.2.R4, VOSviewer v1.6.19, and Microsoft Excel 2019 were utilized for analyzing the following terms: countries, institutions, authors, journals, references, and keywords. There were 1144 articles. The highest number of articles is in the USA, followed by Italy. University of California System, Harvard University, and Johns Hopkins University were the top 3 most productive institutions with publications in this field of research. Journal of Infectious Diseases ranked first with the highest publications (532 records), followed by Immunology (362 records), and Cardiac Cardiovascular Systems (242 records). Keyword co-occurrence analysis showed antiretroviral therapy, myocardial infarction, and protease inhibitors, etc. Keyword cluster analysis obtained 13 categories, which were roughly divided into 3 themes: (1) cardiovascular disease that has occurred or may occur; (2) HIV acquisitions that have occurred; (3) risk factors for cardiovascular disease. The article obtained the hotspots and trends and provided references for subsequent research. Based on the keyword citation burst detection analysis, we speculated that heart failure, risk, subclinical atherosclerosis, infection, and association were the research hotspots in recent years, which had a certain predictive effect on the future research direction.

Strategies for identification of elite Hevea brasiliensis genotypes tolerant to ALF disease from half-sib and full-sib population

Natural Rubber (NR) from Hevea brasiliensis tree is an important commercial commodity worldwide. In general, many Hevea cultivars are vulnerable to abnormal leaf fall (ALF) disease caused by Phytophthora spp., which can lead to considerable reduction in crop production. Chemical control of ALF by spraying mineral oil-based copper fungicides is the conventional approach which is harmful to the ecosystem. Development of ALF tolerant varieties of Hevea through conventional breeding is the major objectives of this study. We evaluated the primary agronomy traits and ALF tolerance level of the newly developed Hevea clones using in vitro leaf disc bioassay as well as field screening for disease incidence consecutively for three years. Variation in disease infestation was observed among genotypes. Based on field screening, the clones which showed better field tolerance against ALF than the parental clones were selected. Clone 683 was identified as one of the most desirable genotypes which had vigorous growth as well as high crop yield in addition to ALF tolerance. The study also confirms the reliability of in vitro leaf disc bioassay technique for screening against ALF across genotypes for its inherent variability. This technique is rapid and easier and can be completed within 96 hours. This approach could reduce the burden of screening larger breeding population to a manageable size to enhance the efficiency of selection in ALF disease resistance breeding programs. Selected fast growing, high yielding ALF tolerant clones, could be further evaluated in on farm trials for recommending to the growers in the traditional region of rubber growing tracts.

First Report of Leaf Spot Caused by Alternaria alternata on Chard (Beta vulgaris var. cicla L.) in China.

Chard (Beta vulgaris var. cicla L.) is popular vegetable in China. In June 2023, a leaf spot disease was observed on Chard plants in Hunan Province (27°46'10.99″N, 112°05'52.80″E), China. The disease incidence was 30% in a surveyed of about 500 plants. Symptoms began as many light brown round- to polygon-shaped spots on chard leaves, then developed and enlarged into grayish-white lesions, with the edge of the spots brown to dark brown. A total of 10 symptomatic samples were randomly collected. To identify the pathogen, symptomatic tissues (0.5 × 0.5 cm) from the lesion margin surface were sterilized with 75% ethanol for 30 s and 2% NaClO for 1 min, rinsed 3 times with sterile water, air dried. The sterile pieces were placed on potato dextrose agar (PDA) and incubated at 25°C. A total of nine isolates were obtained. Fungal colonies cultured on potato carrot agar (PCA) were almost the same as each other, and two representative isolates (TC0, TC10) were used for further identification. On PCA, the fungal hyphae were initially white and finally gray-brown with flocculent aerial mycelia. Conidia were solitary or in chains, with various shapes, mostly subglobose, the size was 13.2 to 28.0 μm long and 5.8 to 13.0 μm wide (n = 30). The cultural and morphological characteristics of isolates were similar to those of Alternaria sp (Simmons et al. 2007). For molecular identification, four loci, ITS (White et al. 1990), RPB2 (O'Donnell, 2022), H3 (Zheng et al. 2015), and GAPDH (Berbee et al. 1999), were sequenced from two representative isolates (TC0, TC10). Compared with a reference isolate, Alternaria alternata strain CBS 107.27, GenBank accession nos. KP124300.1 (ITS), KP124768.1 (RPB2), KP124157.1 (GAPDH). The ITS, RPB2, and GAPDH sequences of TC0 and TC10 showed 99% (502 of 504 bp ), 100% (753 of 753 bp), and 99% (560 of 561 bp) similarity, respectively. Compared with a reference isolate, A. alternata isolate 21-5, GenBank accession no. MN840996.1 (H3), H3 sequences of TC0 and TC10 showed 99% (399 of 401 bp) similarity. The sequences of two isolates (TC0, TC10) were deposited in GenBank with accession numbers PP837733.1, PP565404.1(ITS), PP839298.1, PP573905.1(RPB2), PP839299.1, PP573904.1 (GAPDH), and PP839297.1, PP573903.1(H3). Phylogenetic trees were constructed using the sequences and showed that isolates (TC0, TC10) were in the same clade with A. alternata strains. TC0 and TC10 were identified as A. alternata based on the morphological characteristics and molecular phylogeny. Pathogenicity testing was conducted on six-month-old healthy plants, (cv. Green Stalk), three plants were inoculated by spraying spore solution (1 × 106 conidia/mL), and three plants were sprayed with sterile water as a control. The pathogenicity test was performed 3 times. Plants were maintained at 28°C and >80% RH. Plants showed symptoms after 30 days, symptoms were observed similar to those of the original infected plants, control plants were asymptomatic. The fungus was reisolated, confirmed as A. alternata based on conidial characteristics, no pathogenic fungus was isolated from the control plants. A. alternata has previously been reported on beet (also Beta vulgaris) in China (Tai, F. L. 1979; Zhuang, W. Y. 2005). To our knowledge, this is the first report of leaf spot caused by A. alternata on chard in China. This result may expand the etiological study of A. alternata and the control strategy of Chard leaf spot.

Evaluating the impact of biogenic nanoparticles and pesticide application in controlling cotton leaf curl virus disease (CLCuD) in cotton (Gossypium hirsutum L.)

BackgroundCotton leaf curl virus disease (CLCuD) is one of the major concerns for cotton growers. The traditional approach to managing CLCuD involves the control of the vector (whitefly) population through the use of pesticides. This study compares the efficacy of zinc oxide, iron oxide, copper and silver nanoparticles with conventional pesticides. Nanoparticles dose was optimized by evaluating their phytotoxic threshold in our previous study. In this study, optimized doses of nanoparticles such as zinc oxide (100 ppm), iron oxide (50 ppm), copper (50 ppm) and silver nanoparticles (25 ppm) were applied in a field trial of cotton against cotton leaf curl virus disease (CLCuD). Morphological parameters (height of stem, monopodial branches, sympodial branches, staple length, boll weight and number of bolls), yield parameters (seed cotton yield and ginning outturn), chlorophyll content (chlorophyll a, chlorophyll b, carotenoids and total chlorophyll), biochemical parameters (superoxide dismutase (SOD), peroxidase (POD), ascorbate peroxidase (APX), catalase (CAT), hydrogen peroxide (H2O2) and electrolyte leakage) and disease parameters (reduction infection, disease severity and disease incidence) were determined in this study.ResultsThe incidence of cotton leaf curl virus was confirmed by triple antibody sandwich–enzyme-linked immunosorbent assay (TAS-ELISA). The pesticide Imidacloprid significantly reduced the infection by 79.3%. However, in comparison to pesticide, application of nanoparticles also reduced the infection. ZnO NPs reduced the infection by 42.33%, FeO NPs by 41%, Cu NPs by 34.7%, and Ag NPs by 44.8%. Moreover, these nanoparticles also improved the plant growth parameters as compared to control treatment. ZnO NPs enhanced morphological, yield parameters, and chlorophyll content by 36%, 22%, and 29%, respectively. FeO NPs showed improvements by 38%, 21%, and 29%; Cu NPs 39%, 25%, and 29%; and Ag NPs 31%, 19%, and 18%, respectively.ConclusionAlthough treatment pesticide showed the least disease incidence compared to nanoparticles, nanoparticles are eco-friendly and safe as compared to pesticides. Farmers can apply these nanoparticles at their optimal thresholds through foliar application as an alternative to traditional pesticides. It is concluded that nanocomposites and hybrid modes may be used for managing CLCuD efficiently in the future.Graphical abstract

Benefit of Probiotics on Cardiovascular Health- A Narrative Review

Coronary artery disease (CAD) is a leading cause of death globally and a prevalent cardiovascular disease (CVD) in which plaque buildup in artery walls results in inadequate blood flow. Risk factors for CAD include hypertension, inflammation, diabetes, and poor diet. In the past few decades, research has emerged on the employment of probiotics in cardiovascular health, particularly focused on methods for using probiotics as preventative measures for the risk factors of CAD. Probiotics can reduce hypertension and inflammation, improve insulin sensitivity, and possibly reduce salt levels in individuals with high-sodium diets. Still, more research needs to be done on the safety and considerations of administering probiotics and their underlying mechanisms since the evidence is predominantly experimental. Probiotics have proven to be a valuable research point given the urgency and incidence rates of coronary artery disease.

Insonmia: cardiovascular risk factor in adult people

Introduction. Cardiovascular diseases (CVD) will be the cause of 24.2 million deaths in the world in 2030 and the poor quality and quantity of people's sleep are increasingly related to their risk factors, including insomnia. Objective. The main objective of this research work was to know the influence of chronic insomnia as a risk factor for cardiovascular diseases in adults. Methodology. The present study is based on an integrative review of the literature of articles published between the years 2012-2024, obtained from the journal portal Scientific Electronic Library Online (SCIELO) and the bibliographic databases SCOPUS, Web of Science (WOS), Library of Medicine National Institutes of Health (PubMed), ProQuest and Google Scholar, results that were organized according to the PRISMA methodology. Results. 11 articles were finally included, derived from primary research works, which describe the relationship and impact of chronic insomnia with cardiovascular diseases, their mortality and morbidity. Conclusions. Chronic insomnia is currently established as a modifiable cardiovascular risk factor; its effective treatment will in the future be a preventive measure that will reduce the incidence, mortality and morbidity rates of different cardiovascular diseases

Defining the Etiology of Renal Allograft Dysfunction Using Banff 2019 Classification: Correlation with Post-Transplant Duration and Creatinine Levels-A Comprehensive Analysis of 200 Renal Biopsies at a Tertiary Care Medical Center Hospital.

Chronic kidney disease is a growing global health issue, contributing significantly to morbidity and mortality. The incidence of end-stage renal disease (ESRD) is approximately 100 per million population. Renal transplantation remains the cornerstone treatment for ESRD, with a projected 20-year survival rate of 60%. We aim to define the etiology of renal allograft dysfunction using the Banff 2019 classification by analyzing 200 renal allograft biopsies in correlation with creatinine levels across post-transplant time frames. 200 renal allograft biopsies are analyzed using the recent Banff 2019 classification with creatinine levels and post-transplant duration correlation. The study included 150 (75%) male patients and 50 (25%) female patients, with the majority 78 (39%) representing the age group of 16-30 years. 36 (18%) biopsies were within 3-month post-transplant, while 92 (46%) were 2-year post-transplant. According to the Banff 2019 classification, 92 (46.0%) transplant rejection biopsies were identified, with most 54 (27%) exhibiting antibody-mediated rejection (Category 2), including 40 (20%) active acute antibody-mediated rejection (ABMR) and 14 (7.0%) chronic active ABMR. T-cell-mediated rejection (TCMR; Category 4) represented 12 (6%) biopsies, including 10 (5%) acute TCMR and 2 (1%) chronic active TCMR. Category 5, the miscellaneous group, represented 100 (50%) biopsies, out of which 32 (16%) exhibited calcineurin inhibitor (CNI) toxicity, 38 (19%) acute tubular necrosis, and 8 (4%) thrombotic microangiopathy. A notable variation in the dysfunction distribution across different post-transplant time frames indicated a temporal evolution in the underlying causes of allograft dysfunction. Specific Banff categories showed a robust association with renal dysfunction, potentially contributing to the elevation of creatinine levels and renal function deterioration. Our study highlights the intricate pathophysiology of renal allograft dysfunction. Most biopsies were attributed to ABMR whereas one-third of biopsies exhibited mixed lesions (ABMR and TCMR or ABMR and calcineurin inhibitor toxicity (CNIT)). Additionally, this study suggests that renal allograft rejection remains a significant contributor to graft dysfunction. A complex interplay between histological findings, Banff classification, and renal function is noted. A significant difference in the distribution of dysfunction across post-transplant time frames is noted suggesting a temporal evolution in the etiology of allograft dysfunction. Certain Banff categories demonstrate a stronger association with renal dysfunction that may influence creatinine level increase and renal function deterioration. In correspondence to the recent Banff 2019 guidelines for diagnosing ABMR, we emphasize the role of C4d staining on immunofluorescence or immunohistochemistry in allograft biopsies as imperative for timely diagnosis and immunosuppressant therapy adjustment, ultimately enhancing graft survival. Further research is needed to elucidate the underlying mechanisms driving renal dysfunction in different Banff categories, ultimately informing personalized management strategies for patients with renal allograft dysfunction. In line with the Banff 2019 guidelines for diagnosing ABMR, this study highlights the critical role of C4d staining through immunofluorescence or immunohistochemistry in allograft biopsies for early diagnosis and timely adjustment of immunosuppressive therapy, ultimately improving graft survival.
