This study evaluated the effects of dietary probiotic-fermented corn wet distillers grains (FCWDGs) on finishing pigs. Three Bacillus subtilis strains (CGMCC21218, CCTCC2022073, and CICC10275) were used to ferment corn wet distillers grains, yielding FCWDGs-1, FCWDGs-2, and FCWDGs-3. A total of 128 130-day-old Anqing six white pigs were randomly assigned to four groups: a control group and groups supplemented with 6% FCWDGs-1 (T1), FCWDGs-2 (T2), and FCWDGs-3 (T3). Over a 60-day trial, FCWDGs significantly enhanced growth performance, with T1 and T3 groups showing higher final weight and average daily gain (ADG) compared to the control (p < 0.05), and feed-to-gain ratios were reduced in all treatments (p < 0.05). Loin muscle depth (LMD) was significantly greater in all treatments (p < 0.05), and the lean meat percentage (LMP) was significantly higher in the T1 group (p < 0.05). Antioxidant activity (T-AOC, SOD, and GSH-Px) was enhanced in all treatments, with the highest values observed in the T1 group (p < 0.05). Notably, FCWDGs reduced heavy-metal residues (As, Pb, Cu) in muscle, liver, and kidney tissues, particularly in the T1 group. The results highlight the potential of Bacillus subtilis-fermented FCWDGs to enhance growth performance and carcass traits, and reduce heavy metal accumulation in pig tissues. Full article

Trypanosoma vivax, a haemoprotozoan of African origin, has spread throughout Latin America, mainly affecting cattle through mechanical transmission by flies. This study reports an outbreak of T. vivax on a dairy farm in the midwestern region of São Paulo State, Brazil. Clinical signs included progressive weight loss, lethargy, hyporexia, reduced milk production, abortions, neurological signs, and deaths. The herd comprised 238 crossbred Holstein-Gir cattle (200 cows, 38 calves). Blood samples were collected from 104 randomly selected cows and all 38 calves to assess hematocrit (HCT) and total plasma protein (TPP), and detect trypomastigote forms using blood and buffy coat smears. PCR was performed on EDTA blood from 30 smear-negative cows. Trypanosoma sp. was identified in 51.9% (54/104) of the smear samples, with morphometric confirmation of T. vivax infection. About 66.6% (20/30) of the smear-negative cows tested positive by PCR, showing the higher sensitivity of molecular tests. Anemia was observed in 56.8% of infected cows, with significantly lower HCT and TPP values than in uninfected animals. The absence of quarantine for new animals, high fly density, and shared needles for oxytocin injections were likely contributing factors. This study underscores the crucial role of molecular diagnostics in accurately investigating outbreaks. Full article

Background: Youth with intellectual disabilities are often marginalised and discriminated against regarding skills development and work opportunities as society seems to place high value on an individual’s intellect. Unemployment levels for youth with intellectual disabilities are significantly higher than youth in the general population, yet youth with intellectual disabilities can become valuable employees. This paper explores the untapped potential for youth with disabilities to access skill development opportunities through participation in sports organisations and events that enable them to become economically active. Methodology: A critical ethnographic approach was adopted as the research design. The sample included six youth with intellectual disabilities, five parents, two vocational trainers, two sports coaches, and two golf managers. Data was gathered through participant observations, semi structured interviews, and reflective journaling. Data was analysed using thematic analysis. Findings: The theme “Hidden treasures in a disabling environment” emerged, highlighting the untapped potential of youth with intellectual disabilities to engage in livelihood activities through participation in sports events. One subtheme was “Invisible and well-hidden resources” reflecting remote training centres leading to missed work opportunities. Research findings highlighted that youth with intellectual disabilities possessed marketable skills, alongside the discovery of substantial unexplored livelihood opportunities in the workforce of sports events.

Background: Type 2 diabetes mellitus (T2DM) is a major contributor to cardiovascular disease worldwide, with insulin resistance (IR) being a central pathophysiological mechanism. The triglyceride–glucose (TyG) index, derived from routine fasting measures, has emerged as a simple yet reliable proxy for IR and is increasingly recognised for its prognostic value in metabolic disorders. Despite growing interest, longitudinal evidence on TyG and incident T2DM, especially within European cohorts, remains limited and inconsistent. Therefore, we aimed to estimate the predictive role of TyG on the development of T2DM in an 8-year follow-up observation of a sample of adult men. Methods: We analysed data from 789 adult men without baseline T2DM, enrolled in the Olivetti Heart Study. Receiver operating characteristic curve analysis was used to determine the optimal TyG threshold for predicting new-onset T2DM. Results: Baseline TyG exhibited a strong, linear association with the subsequent development of T2DM. A TyG value above 4.88 was associated with an approximately twofold increase in risk, both before and after adjustment for confounding factors. Conclusions: The principal findings of this study indicate a significant predictive value of the TyG index in the development of new-onset T2DM. These observations suggest that the TyG index may serve as a low-cost, simple, and non-invasive tool for early cardio-metabolic risk assessment. Full article

Background and Clinical Significance: Membranoproliferative glomerulonephritis (MPGN) is a rare and heterogeneous pattern of immune-mediated glomerular injury, often associated with infections, autoimmune disorders, or monoclonal gammopathies. Idiopathic cases remain a diagnostic challenge and frequently require empirical immunosuppressive treatment. There is increasing interest in environmental triggers that may activate the immune system in genetically or immunologically predisposed individuals. We report an unusual case of idiopathic immune complex-mediated MPGN with a relapsing course potentially associated with vaccine-induced immune reactivation. Case Presentation: A 35-year-old male with no significant medical history aside from untreated dyslipidemia and active smoking presented with a hypertensive emergency and acute kidney injury (AKI). Laboratory investigations revealed nephrotic-range proteinuria, microscopic hematuria, and reduced estimated glomerular filtration rate (eGFR). Kidney biopsy demonstrated type I immune complex-mediated MPGN with a diffuse endocapillary proliferative pattern and granular subendothelial deposits (IgG+++, C3+++, C1q++). An extensive work-up ruled out secondary causes, supporting a diagnosis of idiopathic MPGN. Immunosuppressive therapy with corticosteroids and mycophenolate mofetil led to a partial clinical response. However, after receiving multiple vaccinations, the patient experienced clinical deterioration. A second biopsy revealed persistent proliferative changes and new deposits of IgM++, C4d++, and both kappa and lambda light chains. This prompted a reintroduction of immunosuppressive therapy, which resulted in subsequent clinical improvement. Conclusions: This case supports the hypothesis that vaccine-induced immune reactivation may serve as a potential trigger for disease relapse in idiopathic MPGN. Clinicians should remain alert to environmental stimuli that may influence disease activity in immune-mediated glomerulopathies. Further research is needed to elucidate the underlying immunopathogenic mechanisms. Full article

Background: Growth Differentiation Factor 15 (GDF15) has emerged as a key biomarker and therapeutic target in oncology, with roles extending beyond cancer cachexia. Elevated GDF15 levels correlate with poor prognosis across several solid tumors, including colorectal, gastric, pancreatic, breast, lung, prostate, and head and neck cancers. GDF15 modulates tumor progression through PI3K/AKT, MAPK/ERK, and SMAD2/3 signaling, thereby promoting epithelial-to-mesenchymal transition, metastasis, immune evasion, and chemoresistance via Nrf2 stabilization and oxidative stress regulation. Methods: We performed a narrative review of the literature focusing on the role of GDF15 in solid tumors, with a particular emphasis on head and neck cancers. Results: In head and neck squamous cell carcinoma (HNSCC), GDF15 overexpression is linked to aggressive phenotypes, radioresistance, poor response to induction chemotherapy, and failure of immune checkpoint inhibitors (ICIs). Similar associations are observed in colorectal, pancreatic, and prostate cancer, where GDF15 contributes to metastasis and therapy resistance. Targeting the GDF15-GFRAL axis appears therapeutically promising: the monoclonal antibody ponsegromab improved cachexia-related outcomes in the PROACC-1 trial, while visugromab combined with nivolumab enhanced immune response in ICI-refractory tumors. Conclusions: Further investigation is warranted to delineate the role of GDF15 across malignancies, refine patient selection, and evaluate combinatorial approaches with existing treatments.

By leveraging technology, telepathology, and integration with computer-aided diagnostic tools, digital pathology can improve access to prompt and accurate diagnostics. Methods: Our key steps to implementing digital pathology and transitioning operations to a digital network are assessing existing infrastructure, identifying gaps in connectivity and resources, and creating a workflow tailored to the needs of the healthcare system. Results: We present an approach of implementing digital pathology in Timmins, Northern Ontario, Canada, focusing on addressing regional disparities and the improvements that come alongside utilizing digital pathology. Our results show that digital pathology can provide prompt, efficient and better-quality diagnostic services to rural and un-deserved areas, improving patient care and outcomes. It also represents a cost-effective option with savings from eliminating travel costs, courier costs and additional operational efficiencies. Conclusions: Implementing digital pathology in rural settings presented with challenges related to infrastructure, technical abilities, workforce readiness, cost and other aspects involved in transitioning from traditional microscopy to a fully digital pathway. Digital pathology systems can help ensuring seamless data flow and improving overall healthcare delivery. Telepathology also allows pathologists to provide diagnostic services from a distance, which is particularly beneficial in areas with a shortage of pathologists. Full article

Invasive yeast infections (IYIs) remain a significant cause of morbidity and mortality in patients with hematologic diseases. We retrospectively analyzed 193 IYI episodes among 179 patients admitted to a tertiary hematology hospital (2012–2023). Candida species accounted for 91.7% (n = 177), while non-Candida yeasts comprised 8.3% (n = 16). Among invasive candidiasis, non-albicans Candida spp. were predominant, representing 76.8% (136/177), with C. tropicalis (36.2%, 64/177) being the most frequently isolated species. Among non-Candida yeasts, Cryptococcus neoformans (n = 10) was the most commonly identified pathogen. The incidence and 42-day mortality rate of IYIs were 0.199 and 0.095 per 1000 patient-days, respectively. The 42-day case-fatality rate remained high at 47.7%. In categorical analysis, age >65 years, corticosteroid use, elevated lactate (>2 mmol/L), neutropenia (<500/mm³), vasopressor use, and mechanical ventilation were more common in non-survivors. Primary bloodstream infections were more frequent in non-survivors, whereas catheter-related and abdominal-origin infections were predominant among survivors. Concomitant bacteremia was observed in 32.6% of IYI cases (n = 63), with Enterococcus faecium being the most frequently isolated co-pathogen. Our findings illustrate the evolving epidemiology of IYIs in hematologic patients, marked by the emergence of C. tropicalis as the predominant species, sustained mortality, and frequent bacterial co-infections, collectively reflecting the substantial clinical burden of IYIs.

Lyme borreliosis (LB) is a tick-borne infection of global relevance that remains underrecognized, hindering effective surveillance and diagnosis. This lack of awareness and the limited specificity and low antibody titters of current serological assays underscore the need for improved diagnostic tools. Here, we investigated the molecular fine specificity of IgM antibody responses to five proteins of Borrelia burgdorferi. Materials and Methods: We employed peptide arrays on cellulose support (SPOT synthesis) to screen IgM epitopes and assess cross-reactivity through databank searches and Enzyme-Linked Immunosorbent Assay (ELISA). Validation was performed using ELISA and Receiver Operating Characteristic (ROC) curve analysis. Results: We identified ten IgM epitopes, of which four were classified as specific. The ELISA peptide assay demonstrated a sensitivity of ≥87.3%, specificity of ≥56.2%, and accuracy of ≥66.6%. A bi-specific peptide was subsequently synthesized and evaluated by ELISA using a panel of patient sera representing different pathologies. This result showed a sensitivity of 85.0% and a specificity of 100.0%, with significant differences in cross-reactivity between the leptospirosis and syphilis groups. Conclusions: These findings indicate that the identified peptide combinations could facilitate the development of new, highly specific serodiagnostic assays, thereby enhancing public health initiatives and epidemiological studies.

The objective of this study is to evaluate the trabecular structure in hypodivergent individuals using fractal analysis, with a particular focus on specific mandibular regions. This study aims to assess the impact of hypodivergent growth patterns on bone microarchitecture. This research involved a methodological approach using panoramic radiographs to assess trabecular structure at specific regions of the mandible using fractal analyses. The dimensions of the fractals were calculated with the use of the box-counting technique by the software Image J (v1.53c; Bethesda, MD, USA, National Institutes of Health), while the statistical evaluations were carried out with the Jamovi Software (The Jamovi Project, version 2.3.21.0). The study found significant differences in fractal dimension values between hypodivergent individuals and the control group, particularly in the condyle and angulus regions, indicating a less complex trabecular structure in hypodivergent individuals. This study concludes that individuals with a hypodivergent growth pattern exhibit alterations in trabecular bone structure within the mandibular condyle and angulus regions, characterized by reduced complexity. These findings suggest that increased occlusal forces and mechanical stress associated with this growth pattern may contribute to changes in trabecular architecture. Understanding these variations is essential for orthodontic and maxillofacial diagnosis, treatment planning, and biomechanical considerations, particularly in cases requiring vertical dimension management or anchorage control.

Calcium ameliorates salt-related growth defects in plants. The objective of this study was to determine whether supplying calcium through a seed enrichment technique enhances the germinability and early growth of timothy (Phleum pratense L.) under saline conditions. For seed enrichment, timothy seeds were soaked in CaCl₂ solutions at concentrations of 50 mM or 100 mM for 24 h at room temperature. Seeds treated with distilled water served as the control. Under distilled water conditions, germination rates among the seeds showed minimal variation, approximately 95% on average. However, in a 200 mM NaCl environment, the germination rate of the control seeds significantly decreased to 25%, while the germination rates of the Ca-enriched seeds remained high, exceeding 86%. Additionally, the Ca-enriched seeds germinated more quickly than the control seeds. When plants were grown with distilled water, the total dry matter weights did not differ significantly among the treatment types. However, under salt stress with 100 mM NaCl, the plants derived from Ca-enriched seeds thrived and exhibited higher dry matter weights compared to the control plants. The Ca-enriched seeds contained more soluble sugars and demonstrated higher catalase activity than the control seeds, and their corresponding plants accumulated less sodium under salt stress compared to the control plants. Seed enrichment is an effective technique for supplying calcium to timothy, and a concentration of 50 mM of CaCl₂ in the treatment solution is sufficient to achieve salt tolerance. Full article

The current study focuses on a preliminary evaluation of the use of solid residues produced from the distillation of selected medicinal and aromatic plants (MAP) as fertilizers for alkaline soils. Specifically, the residues of hemp (Cannabis sativa L.), helichrysum (Helichrysum Italicum (Roth) G. Don), lavender (Lavandula angustifolia Mill.), oregano (Origanum vulgare L.), rosemary (Rosmarinus officinalis L.) and sage (Salvia officinalis L.) were added in an alkaline and calcareous soil at the rates of 0 (control), 1, 2, 4 and 8%, in three replications (treatments), and the treated soils were analyzed. The results showed that upon application of the residues, soil electrical conductivity (EC), organic C, total N and the C/N ratio significantly increased, especially at the 4 and 8% rates. The same was found for soil available P, K, B, Cu and Mn. The effects of the residues on soil pH, cation exchange capacity (CEC) and available Zn and Fe were rather inconclusive, whereas soil available N significantly decreased, which was somewhat unexpected. From the different application rates tested, it seems that all residues could improve soil fertility (except N?) when they were applied to soil at rates of 2% and above, without exceeding the 8% rate. The reasons for the latter statement are soil EC and available Mn: the doubling of EC upon application of the residues and the excessive increase in soil available Mn in treatments with 8% residues raise concerns of soil salinization and Mn phytotoxicity risks, respectively. This work provides the first step towards the potential agronomic use of solid residues from MAP distillation in alkaline soils. However, for the establishment of such a perspective, further research is needed in respect to the effect of residues on plant growth and soil properties, by means of at least pot experiments. Based on the results of the current study, the undesirable effect of residues on soil available N should be investigated in depth, since N is the most important essential element for plant growth, and possible risks of micronutrient phytotoxicities should also be studied. In addition, application rates between 2 and 4% should be studied extensively in order to recommend optimum application rates of residues to producers. Full article

Inonotus obliquus, a medicinal mushroom valued for its bioactive compounds, has not been previously characterized from Romanian sources. This study presents the first comprehensive chemical and biological screening of I. obliquus, introducing novel polymer-based encapsulation systems to enhance the stability and bioavailability of its bioactive constituents. Two distinct delivery systems were designed to enhance the functionality of I. obliquus extracts: (i) microencapsulation in maltodextrin (MIO) and (ii) a sequential approach involving preparation of silver nanoparticle-loaded I. obliquus (IO–AgNPs), followed by microencapsulation to yield the hybrid MIO–AgNP system. Comprehensive metabolite profiling using GC–MS and ESI–QTOF–MS revealed 142 bioactive constituents, including terpenoids, flavonoids, phenolic acids, amino acids, coumarins, styrylpyrones, fatty acids, and phytosterols. Structural integrity and successful encapsulation were confirmed by XRD, FTIR, and SEM analyses. Both IO–AgNPs and MIO–AgNPs demonstrated potent antioxidant activity, significant acetylcholinesterase inhibition, and robust antimicrobial effects against Staphylococcus aureus, Bacillus cereus, Pseudomonas aeruginosa, and Escherichia coli. Cytotoxicity assays revealed pronounced activity against MCF-7, HCT116, and HeLa cell lines, with MIO–AgNPs exhibiting superior efficacy. The synergistic integration of maltodextrin and AgNPs enhanced compound stability and bioactivity. As the first report on Romanian I. obliquus, this study highlights its therapeutic potential and establishes polymer-based nanoencapsulation as an effective strategy for optimizing its applications in combating microbial resistance and cancer.

Background/Objectives: Human breast milk is a biologically active fluid. It contains immune cells, stem cells, epithelial cells, and lactocytes. These components may support infant development and immune defense. While milk composition is known to vary with physiological and nutritional factors, the impact of the home environment remains poorly understood. The aim of this study was to examine how selected conditions affect the cellular composition of breast milk. Methods: We conducted a cross-sectional study involving 49 lactating mothers of healthy infants under 6 months of age. Breast milk samples were analyzed using flow cytometry. We measured proportions of immune cells (CD3⁺, CD4⁺, CD8⁺, CD19⁺, and CD16/56⁺), hematopoietic stem cells (CD34⁺), mesenchymal stem cells (CD105⁺, CD73⁺, and CD44⁺), and lactocytes (CD326⁺ CD73⁺ and CD326⁺ CD73⁻ phenotypes). Participants completed a questionnaire assessing number of children, co-sleeping, pet ownership, and number of household members. Results: Mothers with more than one child showed higher percentages of CD4⁺ (p = 0.047) and CD8⁺ (p = 0.031) T cells and fewer CD73⁺ lactocytes (p = 0.028). Co-sleeping was associated with lower levels of CD3⁺ T cells in milk (p = 0.021). Pet ownership correlated with a lower proportion of cytotoxic CD8⁺ cells (p = 0.048). The number of household members had no significant effect. Conclusions: Domestic factors such as number of children, co-sleeping, and pet exposure are associated with shifts in the immune and lactocyte cell composition of breast milk. These findings suggest that breast milk dynamically adapts to maternal and household-level immune stimuli. Full article

Background/Objectives: Axial spondyloarthritis (axSpA) is a chronic immune-mediated inflammatory disorder affecting the spine and sacroiliac joints, with variable clinical expression. This study assessed serum levels of inflammatory (TNF-α, IL-17A) and metabolic (leptin, adiponectin) biomarkers and their associations with disease activity, inflammation, structural damage, and comorbidities. Methods: This prospective cross-sectional study assessed 89 axSpA patients using clinical, laboratory, and radiological evaluations. Disease activity was measured using ASDAS-CRP and BASDAI scores. Radiographic damage was quantified using the Modified Stoke Ankylosing Spondylitis Spine Score (mSASSS). Serum concentrations of TNF-α, IL-17A, leptin, and adiponectin were quantified by enzyme-linked immunosorbent assay (ELISA). Clinical and imaging correlations were analyzed. Results: Serum leptin levels correlated significantly with higher disease activity scores, inflammatory markers (CRP, ESR), radiographic progression (syndesmophyte formation, mSASSS), and arterial hypertension. Adiponectin levels were inversely associated with disease activity, structural damage, and arterial hypertension, suggesting anti-inflammatory, bone- and cardio-protective properties. TNF-α levels showed an association with inflammatory markers and were higher in patients with peripheral enthesitis. IL-17A levels were weakly correlated with disease activity and structural severity and were significantly lower in patients with a history of anterior uveitis. Conclusions: Leptin and adiponectin may serve as complementary biomarkers in axSpA, reflecting both inflammatory burden and structural damage. While TNF-α and IL-17A remain key therapeutic targets, their correlation with structural changes appears limited. Biomarker profiling could support personalized disease monitoring. Longitudinal studies are needed to validate prognostic implications. Full article
