Background: Adolescence is a critical period for developing self-perception, emotional well-being, and health behaviors. Mental health disorders represent a substantial burden for adolescents worldwide. This study examines self-perceived health, mood, and substance use among adolescents, identifying associated risk factors. Method: A cross-sectional study was conducted with 121 adolescents aged from 14 to 18 from a secondary school in Baix Llobregat, Catalonia. Data were collected through questionnaires, and descriptive and comparative analyses were performed. Results: Poor self-perceived health and negative mood were associated with higher alcohol and tobacco use. Girls exhibited better emotional regulation than boys. Conclusions: Poor health perception and negative mood are linked to increased substance use. Early intervention should focus on emotional well-being and prevention, involving both families and schools. Full article

Background. Pericarditis has a heterogeneous clinical spectrum and rate of relapse. Data on aetiology, real-life treatment strategies, and long-term course from contemporary pericarditis cohorts are lacking. Methods. Pericarditis patients referred to the Cardioimmunology Outpatient Clinic at Padua University Hospital in 2001–2020 were retrospectively included. Kaplan–Meier method was used for recurrence-free survival probability estimation. The appropriateness of treatment was assessed based on the European Society of Cardiology guidelines. Results. One-hundred forty-four patients (57% males, mean age 50 years) followed up for 18 months (IQR 7–45) were included; of those, 52% had acute, 35% recurrent, 8% incessant, and 5% chronic pericarditis; 9% had cardiac tamponade at diagnosis. Time to pericardial effusion resolution was 53 days (IQR 16–124); median medical treatment duration was 87 days (IQR 48–148). Treatment was readjusted following the ESC guidelines for nonsteroidal anti-inflammatory drugs in 29% of the cases, steroids in 12%, and colchicine in 25%. Eleven (8%) patients were treated with anti-IL1 agents. Recurrence-free survival probability was 86% at 1st-year follow-up, and 23 patients (16%) had at least one recurrence, with a mean of two relapses per patient. Compared to patients without recurrences, they had a higher frequency of cardiac tamponade (27% vs. 6%, p = 0.006) and left bundle branch block (14% vs. 1%, p = 0.034). Out of the 144 patients, 5 (3%) were diagnosed as having constrictive pericarditis at first evaluation at our clinic, underwent successful pericardiectomy, and are currently alive and asymptomatic. Conclusions. When treated following a guideline-based approach, pericarditis has a favourable evolution. A relevant quote of cases benefits from the treatment readjustment of previously prescribed medical therapy when not in line with ESC recommendations. Cases relapsing despite treatment readjustment should receive anti-IL1 therapies. Full article

Capecitabine (CAP) is one of the most commonly prescribed fluoropyrimidines in oncology, especially in the treatment of colon cancer. Cardiac toxicity is a severe and potentially lethal adverse drug reaction (ADR) against fluoropyrimidines. Cardiac ADRs, such as myocardial infarction (MI), heart failure (HF), arrhythmias, and a number of cardiomyopathies, are reported for these molecules. To have a better understanding of the risk–benefit ratio of colon cancer therapy, a pharmacovigilance study of real-world evidence of the cardiac toxicity of antineoplastic agents is required. Aim: This post-marketing research on CAP aims to assess the risk of cardiac toxicity. Five other antitumor drugs used in colorectal cancer, i.e., 5-fluorouracil (5-FU), irinotecan (IRI), oxaliplatin (OX), bevacizumab (BEV) and panitumumab (PAN), were also studied to create a relative profile of observed cardiotoxicity. Methods: A retrospective study based on reports submitted in the EudraVigilance (EV) database until 28 July 2024 was conducted. Using the aggregated data from EV, a descriptive analysis and disproportionality analysis of cardiac ADRs induced by fluoropyrimidines were performed. To evaluate the disproportionality of the signals, Reporting Odds Ratio (ROR) and 95% confidence interval (95% CI) were calculated by comparison with other drugs used in colorectal cancer: 5-FU, IRI, OX, BEV, and PAN. Results: “Cardiac disorders” represent 3.4% of the total reports for CAP. The value is comparable to 5-FU, but higher than for other drugs. t was observed that there are no significant differences in the occurrence of cardiac ADRs in patients exposed to CAP and 5-FU treatments, and in particular MI and HF. Compared to 5-FU, which could produce cardiac arrythmias with a higher probability than all other drugs, CAP has a higher probability of reporting this ADR only in comparison with IRI (ROR: 1.2971; 95% CI: 1.0196-1.6502). Conclusions: CAP induces adverse cardiovascular reactions, especially MI, HF, and cardiomyopathies. Arrhythmias have been shown to be side effects more frequent associated with 5-FU than with CAP. The results emphasize the need for a rigorous cardiovascular monitoring of patients following treatment with CAP or 5-FU and especially for those with pre-existing cardiac pathology. Full article

Background: Pediatric pain significantly affects children’s lives, leading to school absenteeism, impaired social interactions, and psychological distress. The perception of sensory signals as pain is influenced by the brain’s noradrenergic system, and recent evidence suggests that chronic pain may impact cognitive functioning and emotional regulation. Attention-Deficit/Hyperactivity Disorder (ADHD) is associated with alterations in the dopaminergic/noradrenergic systems, which could affect pain perception. Pain-associated conditions and frequent analgesic use in childhood may be linked to ADHD development and could serve as early indicators, yet data on this potential association remain limited. Study Aim: This population-based case-control study in Israel aimed to assess the prevalence of pain-related diagnoses prior to ADHD diagnosis in children aged 5 to 18. The study included children registered with Leumit Health Services (LHS) between 1 January 2006, and 30 June 2021. Children diagnosed with ADHD were compared to matched controls, selected based on age, gender, socioeconomic status, and other sociodemographic factors, who were never diagnosed with ADHD during the study period. Results: Children with ADHD (N = 18,756) and controls (N = 37,512) were precisely matched for sociodemographic characteristics. Individuals with ADHD exhibited significantly higher frequencies of diverse pain conditions, including those associated with illness [headache, earaches, and throat pain (odds ratios [OR] = 1.156 [95%CI 1.085, 1.232], 1.295 [95%CI 1.217, 1.377], and 1.080 [95%CI 1.019, 1.145], respectively; p < 0.01)] and injury [sprains and strains (OR = 1.233 [95% CI 1.104,1.376)]. Analgesics were more frequently purchased by individuals with ADHD, particularly paracetamol (OR = 1.194 [95%CI 1.152, 1.237], p < 0.001) and ibuprofen (OR = 1.366 [95%CI 1.318, 1.416], p = 0.001). Conclusions: This study highlights a potential connection between ADHD and pediatric pain. The elevated rates of pain diagnoses and analgesic usage among children with ADHD underscore the need for further research. Full article

Triple-negative breast cancer (TNBC) is a highly aggressive subtype with limited therapeutic options, leading to higher relapse rates and mortality. Identifying prognostic biomarkers like caveolin-1 (CAV1) is crucial for personalized treatment. CAV1 influences tumor progression and chemotherapy response, particularly through its interaction with the tumor microenvironment (TME) and cancer metabolism. Understanding the prognostic value of CAV1 in different cellular compartments is essential for its clinical application in TNBC. In the methods section CAV1 gene expression in TNBC was evaluated using in silico analysis, followed by the immunohistochemical staining of tumor cytoplasm (cCAV1) and stromal cells (sCAV1) in 58 early-stage TNBC patients. Statistical analyses were performed to correlate CAV1 expression with clinicopathological features and survival. In the results section, in silico analysis revealed higher CAV1 expression in TNBC, correlating with shorter overall survival. In the patient samples, cCAV1 was observed in 10.3% of cases, and was associated with larger tumors, higher grades, and poorer prognoses. sCAV1 was detected in 42% of cases, associated with less proliferative and less aggressive tumors, but did not significantly impact prognoses. In conclusion, cCAV1 expression is a significant prognostic marker in early-stage TNBC, highlighting the importance of assessing CAV1 in different cellular compartments. Further research is needed to explore the mechanisms and clinical implications of cCAV1. Full article

In health insurance, “moral hazard” describes the concept that coverage without an out-of-pocket cost to consumers could result in health care utilization beyond economically efficient levels. In response, payers in the United States (US) have designed pharmaceutical benefit plans with significant cost exposure (e.g., co-pays, co-insurance, or deductibles). While substantial evidence links patient cost exposure to reduced drug spending, it remains unclear to what degree this translates into greater efficiency or an indiscriminate drop in overall consumption also reducing needed utilization. We conducted a systematic literature review to understand whether commonly implemented utilization management (UM) strategies and insurance designs with a behavioral or value-based (BID/VBID) component have been explored as tools to mitigate moral hazard and to assess how cost-sharing policies and innovative insurance designs impact consumer spending. Eligible studies compared conventional cost-exposure policies to BID/VBID, including tiered cost-sharing and other UM strategies. We found that broad implementation of patient cost exposure is not well supported by empirical evidence assessing efficiency—defined as the use of clinically appropriate services at or below the marginal cost of health care utilization in the contemporary US setting. As a result, payers and policy makers alike ought to explore insurance alternatives that more closely align health care consumption incentives to value of care. Full article

Background: Infective endocarditis (IE) poses significant challenges in cardiovascular medicine, often necessitating valvular surgery to manage severe complications. Postoperative acute kidney injury (AKI) is a notable complication affecting patient outcomes. While clinical and procedural factors have been well studied, the role of radiological renal artery parameters in AKI risk remains underexplored. Methods: This retrospective study analyzed 80 patients with IE who underwent valvular surgery from 2013 to 2021, focusing on postoperative AKI as defined by the Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Radiological parameters, including renal artery calcification, renal ostial calcification, the presence of renal infarctions, and additional arteries, were assessed using preoperative computed tomography (CT). Statistical analyses included binary logistic and linear regression models, Kaplan–Meier survival curves, and Cox proportional hazard regression to explore associations between these parameters and AKI incidence, creatinine levels, and mortality. Results: Out of 80 patients, 31 (38.8%) developed AKI. No significant differences were found in baseline characteristics or radiological parameters between the AKI+ and AKI− groups. Binary logistic and linear regression analyses revealed no substantial relationship between anatomical factors and AKI risk or creatinine levels. However, Cox regression identified “additional renal artery” as a significant predictor of 1-month mortality (HR: 1.747, 95% CI: 1.024–2.979, p = 0.041) but not for 6- or 12-month mortality. Conclusions: Radiological anatomical factors, including calcifications and additional arteries, did not significantly impact AKI risk in IE patients undergoing valvular surgery. However, the presence of additional arteries was associated with increased short-term mortality. These findings suggest the need for further research to elucidate factors contributing to AKI and mortality in this context. Full article

Road maintenance is essential for supporting road safety and user comfort. Developing predictive models for road surface conditions enables highway agencies to optimize maintenance planning and strategies. The international roughness index (IRI) is widely used as a standard for evaluating road surface quality. This study compares the performance of deep neural networks (DNNs) and graph convolutional networks (GCNs) in predicting IRI values. A unique aspect of this research is the inclusion of additional predictor features, such as the type and timing of recent roadwork, hypothesized to affect IRI values. Findings indicate that, overall, the DNN model performs similarly to the GCN model across the entire highway network. Given the predominantly linear structure of national highways and their limited connectivity, the dataset exhibits a low beta index, ranging from 0.5 to 0.75. Additionally, gaps in IRI data collection and discontinuities in certain highway segments present challenges for modeling spatial dependencies. The performance of DNN and GCN models was assessed across the network, with results indicating that DNN outperforms GCN when highway networks are sparsely connected. This research underscores the suitability of DNN for low-connectivity networks like highways, while also highlighting the potential of GCNs in more densely connected settings. Full article

Background/Objectives: Dietary factors may significantly influence pain management in cancer survivors. However, a substantial gap exists regarding the relationship between nutrition and chronic pain in this population. This study examined differences in diet quality and dietary intake between breast cancer survivors (BCS) experiencing chronic pain and healthy controls (HC). It also aimed to understand the associations between dietary elements and pain-related outcomes within the BCS group. Methods: A case-control study was conducted with 12 BCS experiencing chronic pain and 12 HC (ages 18–65). Data collection included body composition, experimental pain assessments, pain-related questionnaires, and a 3-day food diary to calculate diet quality using the Healthy Eating Index-2015 (HEI-2015) and Dietary Inflammatory Index (DII). Statistical analyses evaluated group differences and associations between dietary factors and pain within the BCS group. Results: There were no significant differences in HEI-2015 scores between BCS and HC, but BCS had a significantly lower DII score (p = 0.041), indicating a more anti-inflammatory diet. BCS also showed higher intake of omega-3, vitamins B6, B12, A, D, and magnesium (p < 0.05). While total diet quality scores did not correlate with pain outcomes, several HEI-2015 and DII components, such as dairy, sodium, protein, vitamin C, and vitamin D, showed moderate positive or negative correlations with pain measures. Conclusions: Despite no overall differences in diet quality, BCS with chronic pain consumed more anti-inflammatory nutrients than HC. Complex correlations between specific dietary components and pain outcomes emphasise the need for further research to explore these links for chronic pain management in BCS. Full article

The idea of developing a robot controlled by iris movement to assist physically disabled individuals is, indeed, innovative and has the potential to significantly improve their quality of life. This technology can empower individuals with limited mobility and enhance their ability to interact with their environment. Disability of movement has a huge impact on the lives of physically disabled people. Therefore, there is need to develop a robot that can be controlled using iris movement. The main idea of this work revolves around iris recognition from an eye image, specifically identifying the centroid of the iris. The centroid’s position is then utilized to issue commands to control the robot. This innovative approach leverages iris movement as a means of communication and control, offering a potential breakthrough in assisting individuals with physical disabilities. The proposed method aims to improve the precision and effectiveness of iris recognition by incorporating advanced segmentation techniques and fuzzy clustering methods. Fast gradient filters using a fuzzy inference system (FIS) are employed to separate the iris from its surroundings. Then, the bald eagle search (BES) algorithm is employed to locate and isolate the iris region. Subsequently, the fuzzy KNN algorithm is applied for the matching process. This combined methodology aims to improve the overall performance of iris recognition systems by leveraging advanced segmentation, search, and classification techniques. The results of the proposed model are validated using the true success rate (TSR) and compared to those of other existing models. These results highlight the effectiveness of the proposed method for the 400 tested images representing 40 people. Full article

In this study, the production of functional beverages of Zuccagnia punctata Cav. (jarilla), a native medicinal plant from Argentina, and Vaccinium corymbosum (blueberry), with lemon honey as a sweetener, is described. The beverage was formulated by using jarilla extract and blueberry juice with maltodextrin as an encapsulant material. The beverage was dried by both spray-drying and freeze-drying. Both beverages showed high water solubility with adequate features for handling, transport, and storage. The chromatic parameters indicate tones of mauve. Both the total polyphenol and flavonoid contents were retained after being spray-dried (92 and 100%, respectively). The anthocyanins were less stable under spray-dried conditions (58% retained). Both beverages showed high scavenger capacity on ABTS^•+, HO^•, and H₂O₂ (SC₅₀ between 3.56 and 36.90 µg GAE/mL) and exhibited in vitro inhibitor potential of α-glucosidase, α-amylase, and lipase activities (IC₅₀ of between 2.97 and 27.19 µg GAE/mL). The powdered beverage obtained by spray-drying presented the greatest preference in sensory tests. The beverages were neither toxic nor mutagenic in the concentration range with biological activity. During short-term storage, both beverages showed stability. The results obtained would support the use of a powdered beverage made from an Argentinean native plant and blueberries as a functional food. Full article

As a highly sensitive vibrational technique, Raman spectroscopy (RS) can provide valuable chemical and molecular data useful to characterise animal cell types, tissues and organs. As a label-free, rapid detection method, RS has been considered a valuable asset in forensics, biology and medicine. The technique has been applied to zebrafish for various purposes, including physiological, biochemical or bioaccumulation analyses. The available data point out its potential for the early diagnosis of detrimental effects elicited by toxicant exposure. Nevertheless, no baseline spectra are available for zebrafish embryos and larvae that could allow for suitable planning of toxicological assessments, comparison with toxicant-elicited spectra or mechanistic understanding of biochemical and physiological responses to the exposures. With this in mind, this work carried out a baseline characterisation of Raman spectra of zebrafish embryos and larvae throughout early development. Raman spectra were recorded from the iris, forebrain, melanocytes, heart, muscle and swim bladder between 24 and 168 h post-fertilisation. A chemometrics approach, based on partial least-squares discriminant analysis (PLS-DA), was used to obtain a Raman characterisation of each tissue or organ. In total, 117 Raman bands were identified, of which 24 were well represented and, thus, retained in the data analysed. Only three bands were found to be common to all organs and tissues. The PLS-DA provided a tentative Raman spectral fingerprint typical of each tissue or organ, reflecting the ongoing developmental dynamics. The bands showed frequencies previously assigned to collagen, cholesterol, various essential amino acids, carbohydrates and nucleic acids. Full article

Extensive research on tuberculosis (TB) and HIV co-infection reveals the diverse prevalence and co-epidemic patterns across populations, necessitating tailored public health strategies. Co-infection is bidirectional; individuals with HIV are more susceptible to TB, and vice versa. Antiretroviral therapy (ART) and antituberculosis treatment (ATT) are critical for managing these conditions, but pose risks due to drug–pathogen and drug–drug interactions, potentially leading to immune reconstitution inflammatory syndrome (IRIS) in patients with HIV/AIDS. IRIS, often triggered by highly active antiretroviral therapy (HAART), can exacerbate HIV progression, increase drug resistance, and deteriorate patients’ quality of life. Approximately one-third of the global population with HIV is also infected with TB, with extensive drug-resistant (XDR) and multidrug-resistant (MDR) strains posing significant challenges. Latent TB infection (LTBI) further complicates the scenario, as it can progress to active TB, particularly in individuals with both conditions. The global and Indian mortality rates for TB-HIV co-infection remain high, emphasizing the need for new strategies. Additionally, unreported cases and inadequate post-treatment monitoring contribute to the high mortality rate, particularly among patients with LTBI. The complexity of managing HIV-TB co-infection, especially with LTBI, underscores the urgency of addressing these challenges to improve the outcomes for the affected populations. Full article

Background: A negative lifestyle is reported to be related to poor mental health and quality of life (QOL). However, there is little information on this in university students. The objective of the present study was to investigate the association between mental health (i.e., anxiety, depression symptoms and stress), QOL, SWLS and lifestyle parameters (i.e., PA, sleep duration, ST and food habits) among Chilean university students and then to determine the differences in mental health, QOL, SWLS and lifestyle parameters according to gender. Methods: This cross-sectional study included a total of 211 university students (128 females and 83 males) aged 18–28 years. Mental health, QOL and lifestyle were measured through validated questionnaires. Results: Bad food habits (lowest score in the food survey) were linked to anxiety (2.3 [0.22–4.36], p = 0.03), depressive symptoms (3.75 [1.54–5.9], p = 0.001) and stress (2.24 [0.31–4.17], p = 0.023). Furthermore, <6 h of sleep was related to poorer mental health (13.5 [7.6–19.5], p = 0.001), anxiety (4.2 [2.0–6.4], p < 0.001), depressive symptoms (5.5 [3.2–7.9], p < 0.001) and stress (3.8 [1.8–5.9], p < 0.001). In addition, ≥4 h of ST was linked positively to negative mental health (8.3 [2.86–13.7], p = 0.003), depressive symptoms (3.45 [1.47–5.4], p = 0.001) and anxiety (3.2 [1.05–5.4], p = 0.004). Non-physical activity was related to the scores for anxiety (2.6 [0.20–5.0], p = 0.030), depression (2.7 [0.009–5.3], p = 0.049) and stress (2.4 [0.12–4.7], p = 0.039). Conclusions: this study showed that unhealthy lifestyle factors (i.e., insufficient sleep, lack of PA and prolonged ST) were strongly associated with poorer mental health and QOL in university students. These findings highlight the importance of addressing these aspects of lifestyle in intervention and health promotion programs aimed at young university students in order to improve their mental health and overall QOL.
