Subsequently, this article attempted to draw attention towards the risk that may be posed by CCHF in the coming scenario, emphasizing the importance of taking proactive measures in anticipation of such risks.

Needs and expectations of healthcare professionals regarding the topic of alcohology: Results of a survey conducted in France in 2022

ContextAlcohol-related health problems represent a significant public health concern, and it is imperative for the healthcare team to accurately perceive and detect these issues to provide appropriate care. The objective of this survey was to evaluate the knowledge, practices, and educational background of healthcare professionals in the field of alcohol-related health concerns, aiming to identify their information requirements. MethodsThis study employs a cross-sectional descriptive survey methodology, in which data were gathered through a digital questionnaire designed for healthcare professionals (including those in medical, paramedical, and medico-social professions) working in addictology services as well as other relevant services across France and its overseas departments. ResultsA total of 611 questionnaires were deemed usable for analysis. A considerable percentage of participants reported their knowledge and skills to be insufficient or very insufficient, with rates of 33 % and 36 %, respectively. Moreover, a significant proportion of respondents (≈ 28 %) stated that they had received no education in addictology. Our results highlight differences in levels of knowledge and competence among the various healthcare settings, notably with lower reported levels of satisfaction in hospital settings (public and private), private practice, and in Harm Reduction Centers. Furthermore, certain professions reported unsatisfactory levels of skills and knowledge in alcohol-related issues, particularly support staff, pharmacists, expert patients, administrative staff, and social workers. These findings suggest the need to enhance knowledge and skills by tailoring interventions according to the specific healthcare settings and professions. Additionally, the priority themes and channels for disseminating information varied depending on age, region, and professional category. ConclusionThis survey reveals a low level of knowledge, practice, and education in addictology, emphasizing the critical need for training. The importance of training extends not only to the priority topics addressed but also to the channels used for dissemination, all while customizing them to suit the age, professional category, structure, and region of healthcare professionals.

Nutritional assessment and medical dietary therapy for management of obesity in patients with non-dialysis chronic kidney disease: a practical guide for endocrinologist, nutritionists and nephrologists. A consensus statement from the Italian society of endocrinology (SIE), working group of the club nutrition-hormones and metabolism; the Italian society of nutraceuticals (SINut), club ketodiets and nutraceuticals "KetoNut-SINut"; and the Italian society of nephrology

Chronic kidney disease (CKD) is a serious health concern with an estimated prevalence of about 13.4% worldwide. It is cause and consequence of various comorbidities, including cardiovascular diseases. In parallel, common pathological conditions closely related to ageing and unhealthy dietary habits increase the risk of CKD development and progression, including type 2 diabetes and obesity. Among these, obesity is either independent risk factor for new onset kidney disease or accelerates the rate of decline of kidney function by multiple mechanisms. Therefore, the role of diets aimed at attaining weight loss in patients with obesity is clearly essential to prevent CKD as to slow disease progression. Various dietary approaches have been licensed for the medical dietary therapy in CKD, including low-protein diet and Mediterranean diet. Interestingly, emerging evidence also support the use of low-carbohydrate/ketogenic diet (LCD/KD) in these patients. More specifically, LCD/KDs may efficiently promote weight loss, improve metabolic parameters, and reduce inflammation and oxidative stress, resulting in a dietary strategy that act globally in managing collateral conditions that are directly and indirectly related to the kidney function. This consensus statement from the Italian Society of Endocrinology (SIE), working group of the Club Nutrition - Hormones and Metabolism; the Italian Society of Nutraceuticals (SINut), Club Ketodiets and Nutraceuticals "KetoNut-SINut"; and the Italian Society of Nephrology (SIN) is intended to be a guide for Endocrinologist, Nutritionists and Nephrologist who deal with the management of patients with obesity with non-dialysis CKD providing a practical guidance on assessing nutritional status and prescribing the optimal diet in order to best manage obesity to prevent CKD and its progression to dialysis.

Rapid detection of nitrite and Listeria monocytogenes in food based on multiple simulated enzyme activities of Fe3O4-ZnO-MnO2 nanocomposites

Food safety has emerged as a paramount concern in global health, prompting innovative approaches to ensure the safety of people's sustenance. In this study, a novel strategy was devised to fabricate Fe3O4-ZnO-MnO2 hybrid nanobiocatalysts, which exhibited remarkable enzymatic activity surpassing that of Horseradish peroxidase (HRP) catalysis. It demonstrated exceptional proficiency in decomposing 3,3′,5,5′-tetramethylbenzidine (TMB) without the need for harsh reaction conditions or the aid of H2O2. We established colorimetric detection systems based on Fe3O4-ZnO-MnO2-TMB both for nitrite (NO2−) and Listeria monocytogenes (LM) in food. Impressively, the detection limit of nitrite reached an astonishingly low level of 0.022 mg L−1, and the detection limit for LM was determined to be 3.5 cfu mL−1. These compelling results unequivocally validate the potential of these hybrid nanobiocatalysts to fortify food safety measures. Moreover, they serve as a valuable reference for the colorimetric detection of diverse analytes and the simultaneous detection of multiple targets.

Immunohistochemical Expression of Cyclin D1 and p16 in Invasive Breast Carcinoma and Its Association with Clinicopathological Parameters.

Invasive breast cancer (IBC) is a significant health concern globally, contributing to substantial morbidity and mortality among women. Dysregulated cellular proliferation, a hallmark of malignancy, involves molecular pathways modulated by proteins such as cyclin D1 and p16. Understanding their roles in IBC pathogenesis and their association with prognostic parameters is crucial for refining treatment strategies. This retrospective study included 50 female IBC patients who underwent modified radical mastectomy. Histopathological evaluation and immunohistochemical staining for cyclin D1 and p16 were conducted. Associations between protein expression and clinicopathological parameters were analyzed using statistical tests. Cyclin D1 was expressed in 76% of cases, significantly associated with lower tumor grade and lower Ki-67 proliferation index. It also correlated with luminal A/B molecular subtypes. p16 expression was observed in 48% of cases, significantly associated with higher tumor grade, higher Ki-67 index, and triple-negative/Her-2 neu-enriched subtypes. Co-expression of cyclin D1 and p16 was noted in 60% of cases. No significant association was found between protein expression and other parameters. Cyclin D1 and p16 exhibit potential as prognostic markers in IBC. Cyclin D1 expression correlates with less aggressive tumor features and luminal subtypes, suggesting a favorable prognosis and potential predictive value for CDK4/6 inhibitor therapy. Conversely, p16 expression associated with aggressive phenotypes, indicating poor prognosis. Further studies are warranted to validate these findings and explore their clinical implications. Integrating these biomarkers into clinical practice may enhance risk stratification and treatment decisions, ultimately improving outcomes for IBC patients.

Spatio-temporal analysis of pulmonary tuberculosis in Astambul District, South Kalimantan, Indonesia 2020-2021

Respiratory tuberculosis (TB) remains a significant global health concern and ranks among the top 10 leading causes of death worldwide, following human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS). Globally, it is estimated that 1.2 billion people are at risk of being infected with tuberculosis, and Indonesia is the country that contributes the third-highest number of TB cases worldwide, behind China and India. Tuberculosis is still a significant issue in South Kalimantan, notably in Banjar Regency. This study is a descriptive study that intends to identify respiratory TB clusters spatially and temporally in Astambul District during 2020–2021 with the SatScan application, which is visualized as a map of respiratory TB clusters using the Quantum GIS 3.28 application. Data on respiratory TB cases collected from the Banjar District Health Office were examined using retrospective space-time scan statistics, employing a Poisson probability model for analysis. This study found 4 respiratory TB clusters, and 2 of them had significant results, namely in 2020 (RR=6.90, p-value=0.000030) and 2021 (RR=5.27, p-value=0.00003). Factors that affect these clusters are population density, the physical condition of houses, humidity levels, and the availability of health facilities.

Burden of oral cancer and associated risk factors at national and state levels: A systematic analysis from the global burden of disease in India, 1990–2021

BackgroundOral cancer is the sixth most prevalent cancer globally, posing a significant health concern, especially in India, where it accounts for one-third of the global cases. Despite high incidence and mortality rates, comprehensive national and regional data on risk factors and trends are scarce. MethodsThis study analyzed data from the Global Burden of Disease (GBD) 2021 report, focusing on the age-standardized incidence rate (ASIR), mortality rate (ASMR), disability-adjusted life years (ASDR), and prevalence rate (ASPR) of oral cancer in India from 1990 to 2021. Joinpoint regression analysis was used to assess trends, and ARIMA models were applied to forecast future trends from 2022 to 2031. ResultsFrom 1990 to 2021, India experienced a moderate increase in oral cancer mortality, with ASMR rising from 5.32 to 5.92, reflecting an annual percentage change (APC) of 11.18 %. ASDR increased from 152.94 to 163.61 (APC of 6.98 %), and ASPR showed a marked rise from 15.71 to 25.46 (APC of 62.06 %). The burden varied significantly across states. Gender disparities were observed, with males consistently exhibiting higher incidence and mortality rates. ARIMA forecasts projected an upward trend in oral cancer metrics from 2022 to 2031, with ASIR expected to reach 10.15 per 100,000 and ASPR 29.38 per 100,000 by 2031. ConclusionsThe study reveals a persistent and growing burden of oral cancer in India, highlighting the influence of lifestyle and socioeconomic factors. Targeted strategies to mitigate risk behaviors, improve early detection, and address disparities are urgently needed to reduce the disease’s impact.

Potential Non-carcinogenic and Carcinogenic Health Risks of Elements of Health Concern Bioaccumulated in Seafood from Local Fish Rafts in Trang Province, Thailand

Marine ecosystems are increasingly contaminated by pollutants from human activities which could impact seafood quality. This study investigated the levels of six potentially toxic elements of health concern including arsenic (As), cadmium (Cd), chromium (Cr), mercury (Hg), nickel (Ni), and lead (Pb). Analyses of those elements were conducted in eleven commercially available seafood species collected from local fish rafts in Trang province, Thailand. The findings revealed variations of element of health concern content among species, with H. raphidea exhibiting significantly high levels. Human health risks were assessed for estimated daily intake and non-carcinogenic and carcinogenic risks. The results indicate potential risks associated with As consumption, especially in the case of H. raphidea. Children (3.0 – 5.9 years) had the greatest vulnerable risks in comparison to other age groups. The levels of elements of health concern in most seafood samples were within safe limits. However, the continuous surveillance, monitoring, and management of these contaminants in seafood are needed, particularly in vulnerable populations.

Marine microplastics enrich antibiotic resistance genes (ARGs), especially extracellular ARGs: An investigation in the East China Sea

The potential of microplastics to carry coexisting pollutants and contribute to combined pollution is a significant health concern. Here we investigate the presence of antibiotic resistance genes (ARGs) in both intracellular ARGs (iARGs) and extracellular ARGs (eARGs) forms, on microplastics collected from the coastal waters of the East China Sea. Our findings revealed that both iARGs and eARGs were enriched on microplastics. Specifically, 6- to 55-fold enrichment of iARGs was found on microplastics, while eARGs were more significantly enriched (5–140 fold). 16s rDNA analysis revealed that microplastics harbored a more diverse microbial community, particularly opportunistic pathogens, compared to surrounding seawater. This contributes to more correlations between bacterial genera and ARGs on microplastics than in sea water. Molecular ecological network analysis indicated that total nitrogen and ammonia were primary determinants of ARG and microbial enrichment on microplastics. This study provides implications for understanding the combined pollution of microplastics and ARGs.

Molecular investigation of Coxiella burnetii, Brucella spp., Ehrlichia spp., and Borrelia spp. among patients suspected of having Crimean-Congo Hemorrhagic Fever in Iran

ObjectivesCrimean-Congo Hemorrhagic Fever (CCHF) is a tick-borne zoonotic viral disease that could be a public health concern. The overlapping of clinical symptoms of some acute bacterial febrile diseases with CCHF is of importance for clinical diagnosis. This study aimed to molecularly examination of Brucella, Coxiella burnetii, Borrelia, and Ehrlichia infections among individuals suspected of CCHF in Iran. MethodsIn this study, 260 serum samples of suspected cases of CCHF with definitively negative laboratory test results for CCHF virus infection, were examined for Brucella spp., Coxiella burnetii, Borrelia spp., and Ehrlichia spp. by Real-time PCR. ResultsAccording to the results, 3.46% and 3.07% of the patients were positive for brucellosis and Q fever, respectively. Notably, no cases of borreliosis or ehrlichiosis were detected. Among the positive cases for brucellosis (N= 9), three cases were identified as Brucella abortus infection. Individuals under the age of 43 displayed a significantly higher positivity rate for Q fever (p < 0.01). Furthermore, patients presenting with chills had a 5.81-fold increased likelihood of being infected with Q fever (95% CI: 1.39–24.26) compared to those without chills. Notably, no other variables demonstrated a statistically significant association with Q fever infection. Discussion and ConclusionsThe results of this study showed that bacterial infections such as Q fever and brucellosis should be considered as differential diagnoses of CCHF. It is recommended that other bacterial infections that can cause early clinical symptoms similar to CCHF should also be taken into consideration in future studies and serological and molecular investigations of these infections should be tested on a wide scale.

Multidrug resistant tuberculosis risk factors in Makassar, Indonesia

Multidrug resistant tuberculosis (MDR-TB) is a significant public health concern in Indonesia, resulting in substantial morbidity and mortality rates. This study aimed to quantify the impact of risk factors of MDR-TB. A case-control study was conducted at Makassar Community Lung Health Center (BBKPM) in Makassar City. A total of 132 respondents, 66 cases, and 66 controls have participated in the study. Data was analyzed using the Stata version 14 tool, odds ratio (OR), and multiple logistic regression. Multiple logistic regression analysis identified significant risk factors for the occurrence of MDR-TB include previous TB treatment (OR=8.46, 95% CI: 3.278-21.858), positive acid-fast bacilli (AFB) sputum (OR=6.40, 95% CI: 2.525-16.260), and adverse drug event (OR=3.45, 95% CI: 1.008-11.867). The probability of developing MDR-TB is 95.9% if there is previous TB treatment with cases of relapse/loss to follow-up/failed treatment, positive AFB sputum, and adverse drug event. The most dominant risk factor for the occurrence of MDR-TB is a previous TB treatment. We suggest that an efficient directly observed treatment shortcourse (DOTS) strategy, particularly in the management of adverse drug event, overseeing and supporting patients who have recovered from MDR-TB, involves the collaboration of MDR-TB healthcare professionals and patient supporters in the Yamali TB community, moving synergistically as an effort to MDR-TB control and prevention.

MicroRNAs in fluorosis pathogenesis: impact on dental, skeletal, and soft tissues.

Fluoride-induced toxicity (fluorosis) poses a significant health concern globally, affecting millions of individuals. Understanding the molecular mechanisms underlying fluorosis, particularly the role of microRNAs (miRNAs), is crucial for developing effective preventive and therapeutic strategies. This review explores the pivotal role of miRNAs in the pathogenesis of fluorosis, particularly examining its impact on both hard (skeletal and dental) and soft (brain, liver, kidney, heart, and reproductive organs) tissues. Skeletal fluorosis manifests as abnormal bone mineralization and structure, while dental fluorosis affects enamel formation. In vitro and in vivo studies suggest a significant involvement of miRNAs in the progression of these conditions. For skeletal fluorosis, miR-124, miR-155, and miR-200c-3phave been identified askeyregulators, while miR-296-5p and miR-214-3pare implicatedin dental fluorosis.Moreover, soft tissue fluorosis encompasses a spectrum of adverse effects on various organs, including the brain, liver, kidneys, heart, and reproductive system. In soft tissues, miRNAs, such as miR-124, miR-200c-3p, miR-132, and miR-34b-5p, havebeen linkedto cellular damage and dysfunction. Notably, miRNAs exert their effectsthrough the modulation ofcritical pathways involved in fluorosis pathology, including Wnt signaling, apoptosis, cell cycle, and autophagy. Understanding the regulatory roles of miRNAs in fluorosis pathogenesis holds promise for identifying biomarkers and therapeutic targets. However, further research is needed to elucidate the molecular mechanisms underlying miRNA-mediated responses to fluoride exposure.Integration ofmiRNA research into fluorosis studies could facilitate the development of diagnostic tools and therapeutic interventions, thus mitigating the detrimental effects of fluorosis on both hard and soft tissues.

Mathurameha ameliorates cardiovascular complications in high-fat diet/low-dose streptozotocin-induced type 2 diabetic rats: insights from histological and proteomic analysis.

Type 2 diabetes mellitus (T2DM) is a global health concern with increasing prevalence. Mathurameha, a Thai herbal formula, has shown promising glucose-lowering effects and positive impacts on biochemical profiles in diabetic rats. The present study investigated the protective effects of Mathurameha on cardiovascular complications in high-fat diet/streptozotocin (HFD/STZ)-induced type 2 diabetic rats using histological and proteomic analyses. Thirty-five male Sprague-Dawley rats were divided into seven groups: normal diet (ND), ND with aqueous extract (ND + AE450), ND with ethanolic extract (ND + EE200), diabetes (DM), DM with AE (DM + AE450), DM with EE (DM + EE200), and DM with metformin (DM + Met). Mathurameha, especially at 200mg/kg EE, significantly reduced adipocyte size, cardiac and vascular abnormalities, collagen deposition, and arterial wall thickness in DM rats. Proteomic analysis of rat aortas revealed 30 significantly altered proteins among the ND, DM, and DM + EE200 groups. These altered proteins are involved in various biological processes related to diabetes. Biochemical assays showed that Mathurameha reduced lipid peroxidation (MDA), increased antioxidant levels (GSH), and decreased the expression of inflammatory markers (ICAM1, TNF-α). In conclusion, Mathurameha exhibited significant protective effects against cardiovascular complications in HFD/STZ-induced type 2 diabetic rats through its antioxidant and anti-inflammatory properties.

Oridonin alleviates inflammation and endoplasmic reticulum stress in pediatric pneumonia via regulating the SIRT1-mediated Wnt/β-catenin signaling pathway.

Pediatric pneumonia is a prevalent and significant health concern worldwide, with elevated morbidity and mortality rates among affected children. This study was designed to elucidate the therapeutic impact of Oridonin (Ori) on pediatric pneumonia and unravel the underlying mechanisms involved. A pediatric infantile pneumonia model was established in mice through intratracheal administration of LPS. Additionally, a cell damage model was created in WI-38 cells by administering LPS. Protein levels were assessed via western blotting, and cell viability was measured with CCK-8. Inflammatory cytokines were quantified through ELISA, and specific assays were employed to evaluate oxidative stress markers. Flow cytometry was utilized to assess cell apoptosis. Ori alleviated lung inflammation, oxidative stress, apoptosis, and endoplasmic reticulum stress (ERS) in LPS-induced pneumonia mice. In addition, Ori increased the viability of LPS-induced pneumonia cells but decreased cell apoptosis. Furthermore, Ori reduced oxidative stress, inflammation, and ERS in LPS-induced pneumonia cells by enhancing SIRT1 to activate the Wnt/β-catenin pathway. This study suggested that Ori inhibited pediatric pneumonia by dampening the inflammatory response, oxidative stress, cell apoptosis, and ERS via the SIRT1/Wnt/β-catenin pathway.

Optimizing Diagnosis of Pediatric Streptococcus pyogenes Infections: A Clinical Prediction Model

Group A Streptococcus (GAS) infections, caused by Streptococcus pyogenes, are a major health concern among children under 12 years, leading to conditions such as tonsillitis, rheumatic fever, and post-streptococcal glomerulonephritis. Accurate diagnosis is essential for effective treatment and prevention. This study aimed to develop and validate a Clinical Prediction Rule (CPR) for predicting the presence of S. pyogenes in throat swabs from children under 12. We analyzed clinical and laboratory data from 1,015 pediatric patients presenting with symptoms suggestive of GAS infection at Federal University Teaching Hospital, Owerri, Imo State, between January 2019 and December 2022. S. pyogenes was first isolated from throat swabs cultured on blood agar, and 233 positive isolates were further identified using Polymerase Chain Reaction (PCR) targeting the Spy 1258 gene, with DNA extracted via boiling and confirmed through phenotypic methods. Data from these 233 identified cases were used to develop and validate the CPR. Variables examined included gender, age, ward of admission, clinical diagnosis, and antibiotic susceptibility. Logistic regression modeling identified significant predictors of S. pyogenes presence, with potential biases minimized through systematic case review, standardized data extraction and cross-checking by multiple reviewers. Among the 233 cases analyzed, the mean age was 4 ± 0.25 years, with 62.7% under age 3. Tonsillitis was the predominant diagnosis, with GAS prevalence ranging from 56.7% to 69.3%. Antibiotic susceptibility test result varied, with significant predictors including Sepsis/Tonsillitis and ear discharge/tonsillitis (p < 0.001). The CPR model demonstrated a sensitivity of 95.4% and a specificity of 36.8%, highlighting its potential to enhance clinical diagnosis and management of GAS infections. This study offers valuable insights into predictors of S. pyogenes infection in pediatric patients and highlights the CPR’s potential for improving clinical diagnosis and management.

Potential biosecurity breaches in poultry farms: presence of free-ranging mammals near laying-hen houses assessed through a camera-trap study

Diligent application and implementation of biosecurity measures stand as one of the most effective measures to prevent disease transmission through direct or indirect interactions between poultry and free-ranging animals. Among these, free-ranging mammals can be hosts or disseminators of several pathogens relevant to poultry and of public health concern. Moreover, evidence of susceptibility to avian influenza virus infection in non-human mammals has raised questions about their potential role in the virus's epidemiology at the domestic animal-wildlife interface. Given this background, this study aimed to identify mammal species occurring near laying-hen houses and characterize the spatiotemporal patterns of these visits. Seven camera traps were deployed for a year-long period in three commercial poultry farms in a densely populated poultry area in Northern Italy. Various methods, including time series analysis and generalized linear models, were employed to analyze daily mammal visits. A total of 1,867 camera trap nights yielded 567 videos of seven species of wild mammals, and 1,866 videos showed domestic pet species (cats and dogs). Coypus (Myocastor coypus) and cats were the two mammals more frequently observed near poultry houses. For wild mammals, visits significantly increased at night, and slightly decreased during the spring season. Overall, the data hereby provided lay the groundwork for designing novel surveillance and intervention strategies to prevent cross-species disease transmission. Moreover, the utilization of visual evidence depicting free-ranging animals approaching poultry houses could assist health authorities in educating and raising awareness among stakeholders about potential risks of pathogen spillover.

Revolutionizing Skin Cancer Treatment: The Rise of PD-1/PDL-1 and CTLA-4 as Key Therapeutic Targets.

Skin cancer is a significant health concern, affecting millions of individuals globally on an annual basis. According to data from the World Health Organization, it stands as the most prevalent form of cancer within the white population. Current treatments for skin cancer typically involve a combination of chemotherapy, radiation therapy, and surgery. However, these methods often come with drawbacks, such as side effects and potential scarring. Therefore, there is a growing need for alternative treatments that can offer effective results with fewer adverse effects, driving ongoing research in skin cancer therapy. The advancement of immune checkpoint inhibitors has been facilitated by a more profound comprehension of the interplay between tumors and the immune system, along with the regulatory mechanisms governing T-cells. As cancer treatment continues to evolve, immunotherapy is emerging as a powerful strategy, leading to a growing interest in the role of immunological checkpoints in skin cancer. Various types of immune checkpoints and their expression, including PD-1, PDL-1, CTLA-4, lymphocyte activation gene 3, and B7-H3, along with their blockers and monoclonal antibodies, have been established for various cancers. PD-1, PDL-1, and CTLA-4 are crucial immune system regulators, acting as brakes to prevent T-- cell overactivation and potential autoimmunity. However, tumors can exploit these checkpoints to evade immune detection. Inhibiting these immune checkpoints can enhance the body's ability to recognize and attack cancer cells. This review focuses on the characteristics of PD-1, PDL-1, and CTLA-4 immune checkpoints, their mechanism of action, and their role in skin cancer. Additionally, it summarizes the ongoing clinical trials sponsored or conducted by various pharmaceutical companies and provides insights into the latest patent data.

Jinhua Hecha – A fermented green tea improves sleep via regulating glutamatergic synapses and gut microbiota

Quality sleep is crucial for preserving the internal equilibrium of the body. Sleep problems have become a predominant global health concern in recent years. Jinhua Hecha (JHHC) is a fermented green tea characterized by high amino acid and low tea polyphenols. In animal experiments, the potential beneficial effects of JHHC on sleep quality were evaluated. 50 mice were categorized into five groups: the normal control (NC) group, the FFZR positive control group, the JHHCG (2.3 g/kg) group, the JHHCZ (1.6 g/kg) group, and the JHHCD (0.7 g/kg) group. The sleep experiments revealed that mice from the JHHC group exhibited a notably extended duration of sleep following the intraperitoneal injection of pentobarbital sodium, with a shortened sleep latency after injection of barbital sodium. These results suggest that JHHC is beneficial for sleep. Mechanistically, transcriptome KEGG enrichment analysis revealed that differentially expressed genes were significantly enriched in the glutamatergic synapse signaling pathway. Immunohistochemistry and multiple immunofluorescence techniques showed decreased protein expressions of GLS, VGLUT2, GluA2, GluA4, GluK1, and mGluR1 in the colon of the JHHC group. Furthermore, an increase in beneficial bacteria such as Lactobacillus, Ligilactobacillus, and Akkermansia, as well as a decrease in Alistipes, were observed in the JHHC group. These results indicate that JHHC can improve sleep, with potential mechanisms involving gut microbiota maintenance and glutamate level reduction.

Exposure assessment of the European adult population to deoxynivalenol – Results from the HBM4EU Aligned Studies

Mycotoxins are natural toxins produced by fungi that may cause adverse health effects thus constituting a public health concern. Deoxynivalenol (DON), a mycotoxin affecting the immune system and causing intestinal disorders, was selected as a priority under the European Human Biomonitoring Initiative (HBM4EU). Urinary total DON levels (tDON) of 1270 participants from six countries were used to characterize the internal exposure of the adult European population and identify the most relevant determinants of exposure. tDON concentrations’ P50 and P95 were in the range of 0.41–10.16 µg/L (0.39–9.05 µg/g crt) and 3.25–46.58 µg/L (2.12–33.50 µg/g crt) respectively. Higher tDON levels were observed for (i) male participants from France and Germany, (ii) samples collected in spring and summer, (iii) participants with a lower educational level, (iv) participants living in rural areas, (v) individuals without a job in France and Luxembourg, while in Portugal higher exposure was observed in working individuals, (vi) individuals with higher consumption of cereals and bread. The proportion of individuals with exposure levels exceeding the HBM-GV of 23 µg/L was 12.3 %, ranging from 0.8 % to 20.7 % in the individual countries. This study on mycotoxins exposure has used post harmonized questionnaire data and validated analytical methodologies for analysis and covered countries representing the four geographical regions of Europe, having produced much needed knowledge on the exposure of the European adult population to deoxynivalenol.
