The Fontan operation has become the primary palliative treatment for patients with a functionally univentricular heart. The population of patients with Fontan circulation is constantly growing and aging. As the number of Fontan patients surviving into adulthood increases, there is a clear need for research on how best to follow these patients and manage their complications. Monitoring blood biomarkers is a promising method for the non-invasive assessment of the Fontan circulation. In this article, we provide a comprehensive review of the available evidence on this topic. The following biomarkers were included: natriuretic peptides, red blood cell distribution width (RDW), cystatin C, high-sensitivity C-reactive protein, vitamin D, parathyroid hormone, von Willebrand factor, carbohydrate antigen 125, lipoproteins, hepatocyte growth factor, troponins, ST2 protein, galectin-3, adrenomedullin, endothelin-1, components of the renin–angiotensin–aldosterone system, norepinephrine, interleukin 6, tumor necrosis factor α, and uric acid. We did not find strong enough data to propose evidence-based recommendations. Nevertheless, significantly elevated levels of brain natriuretic peptide (BNP)/N-terminal prohormone of BNP (NT-proBNP) are most likely associated with the failure of the Fontan circulation. The use of the RDW is also promising. Several biomarkers appear to be useful in certain clinical presentations. Certainly, robust longitudinal, preferably multicenter, prospective studies are needed to determine the sensitivity, specificity, evidence-based cut-off values and overall predictive value of different biomarkers in monitoring Fontan physiology.

SLEEP duration , *SLEEP quality , *SPACE exploration , *REACTIVE oxygen species , *RAPID eye movement sleep , *PEDOMETERS - Abstract
Purpose: Human presence in space is increasingly frequent, but we must not forget that it is a hostile environment. We aimed to study the characteristics of experimental scenarios, to obtain data on human response to isolation, disruption of circadian rhythm and high levels of psychophysical stress. Methods: In these experiments, we evaluated stress response in five young healthy subjects inside an earth-based moon-settlement-like habitat during a 1-week long analog astronaut mission. Wearable devices were used to monitor daily step count of the subjects, physical activity, heart rate during physical exercise and at rest, and sleep parameters. From saliva and urine samples collected every day at awakening, we studied oxy-inflammation biomarkers and hormones (stress and appetite) were studied too. Results: At the end of the week, all subjects revealed an increase in oxidative stress and cortisol levels but no inflammation biomarkers variations, in conjunction with increasing time/daily exercise. Furthermore, a significant decrease in hours of sleep/day, sleep quality, and REM phase of sleep was recorded and correlated with the increase of reactive oxygen species. Conclusion: Oxidative stress increased in a short period of time and may be attributed to the influence of psychological stress during confinement, as well as increased exercise and decreased amount of sleep. On a long-term basis, this could impact performance. [ABSTRACT FROM AUTHOR]

Simple Summary: This review explores cortisol's physiological and behavioral role in canines, focusing on its effects on stress, immune function, and metabolism. Abnormal cortisol levels' clinical and behavioral consequences are discussed, with a particular focus on disorders like Cushing's disease and behavioral problems brought on by stress. In addition to suggesting avenues for future study to enhance canine health and stress management, the findings highlight the significance of cortisol monitoring in veterinary practice and animal welfare. Cortisol, an essential glucocorticoid hormone, is crucial in regulating the stress response and maintaining physiological and behavioral homeostasis in mammals, including dogs. This review explores cortisol's physiological and behavioral role in canines, focusing on its effects on stress, immune function, and metabolism. Various methods of measuring cortisol levels in dogs, invasive (blood, saliva, urine) and non-invasive (hair, fecal assays), are discussed regarding their accuracy and practical applications. The review also highlights the influence of different environmental factors, such as shelter conditions, human interaction, and music, on cortisol levels in dogs. Furthermore, the clinical and behavioral implications of abnormal cortisol levels are examined, with particular attention to conditions like Cushing's disease and stress-related behavioral issues. The findings emphasize the importance of cortisol monitoring in veterinary practice and animal welfare, proposing future research directions to improve canine health and stress management.

Diabetes management is critical for a vast population worldwide, and traditional blood glucose monitoring methods typically require invasive blood sampling, leading to patient discomfort and poor adherence. This study proposes the development of a non-invasive breath-based glucose monitoring system that leverages gas sensors to detect specific volatile organic compounds (VOCs) in exhaled breath, particularly acetone, which correlates with blood glucose levels. The system will utilize metal oxide semiconductor (MOS) sensors and machine learning algorithms to provide accurate real-time glucose readings. By eliminating the need for finger pricks, this innovative device aims to enhance the convenience and compliance of glucose monitoring for diabetic patients, ultimately contributing to better disease management and quality of life. The feasibility, accuracy, and usability of the system will be validated through clinical trials, paving the way for future advancements in diabetes care technologies. [ABSTRACT FROM AUTHOR]

Abstract The continuous search for simple, noninvasive methods for assessing liver fibrosis remains very important to help risk-stratify and follow-up patients with chronic hepatitis C virus (HCV). This study aimed to evaluate the diagnostic performance and accuracy of six serological noninvasive scores for the assessment of liver fibrosis in comparison to liver histopathology. This retrospective cohort study included data from 19501 patients with chronic HCV infection who had liver biopsies as an HCV treatment prerequisite within the Egyptian national HCV treatment program. Six noninvasive scores (FIB-4, APRI, King’s score, Fibro-Q, fibrosis index, Fibro-α score) were evaluated and compared to liver histopathology data in assessing different stages of liver fibrosis. The diagnostic performance for each score was assessed using the area under the receiver-operating characteristic curve (AUROC). All six noninvasive scores were statistically significant for predicting different stages of liver fibrosis. Four scores (FIB-4, King’s score, APRI, and Fibro Q) had a better diagnostic performance for predicting different fibrosis stages. FIB-4, followed by the King’s score, performs better in identifying patients with advanced fibrosis at cutoffs of 2.01 and 16.7, respectively, with AUROC of 0.71 for both, and in predicting cirrhosis at cutoffs of 2.21 and 17.4, respectively with AUROC 0.82 for both. Using noninvasive scores for fibrosis assessment is very important, especially in limited resource settings, to rapidly stratify patients who need more specialized care.

Objective: The aim of this review was to evaluate the currently available scientific evidence on the efficacy of different methods as accelerators of tooth movement during orthodontic treatment: corticotomies, piezocision, micro-osteoperforations (MOP), photobiomodulation (LLLT and LED laser) and microvibrations. Search Methods: A comprehensive search was performed in the PubMed, Google Scholar, Scopus and Medline databases in May 2024. Selection Criteria: We selected randomized controlled trials based on acceleration of tooth movement during orthodontic treatment. Articles that were not randomized controlled trials (RCTs), were not published in the last ten years or corresponded to animal trials as well as those dealing with orthognathic surgery, distraction osteogenesis, electric currents, pulsed electric fields and pharmacological approaches were excluded. Results: Twenty-three studies were included in this review. All trials show accelerated tooth movement after low-level laser application, and seven studies support the efficacy of surgically assisted orthodontic treatment with corticotomies, piezocision or MOP. No article indicates statistically significant differences between the application of microvibration during orthodontic treatment and conventional treatment. No negative effects on the periodontium, loss of dental vitality or serious root resorption were reported in any publication, except in a study carried out with MOP (with an increase in root resorption). Conclusions: There is some evidence that low-level laser therapy and surgical methods are effective techniques in accelerating tooth movement during orthodontic treatment, while the evidence is very weak for vibration.

The common octopus (Octopus vulgaris) is an excellent candidate for aquaculture diversification, due to its biological traits and high market demand. To ensure a high-quality product while maintaining welfare in captive environments, it is crucial to develop non-invasive methods for testing health biomarkers. Proteins found in skin mucus offer a non-invasive approach to monitoring octopus welfare. This study compares the protein profiles in the skin mucus of wild, aquarium-maintained, and senescent specimens to identify welfare biomarkers. A tandem mass tag (TMT) coupled with an Orbitrap Eclipse Tribrid mass spectrometer was used to create a reference dataset from octopus skin mucus, identifying 1496 non-redundant protein groups. Although similar profiles were observed, differences in relative abundances led to the identification of potential biomarkers, including caspase-3-like, protocadherin 4, deleted in malignant brain tumors, thioredoxin, papilin, annexin, cofilin and mucin-4 proteins. Some of these proteins also revealed potential as bioactive peptides. This investigation provides the most extensive analysis of the skin mucus proteome in the common octopus and is the first to explore how aquarium maintenance and senescence alter the mucus proteome. This research highlights the potential of skin mucus protein/peptides as non-invasive monitoring biomarkers in cultured animals. [ABSTRACT FROM AUTHOR]

Objective. To test the hypothesis that there are differences between three mean values of sleep latency (SL) when falling asleep: when accompanied by audio stimuli based on binaural beats (BB), after listening to suggestive instructions on how to relax the body, and accompanied by BB-based audio stimuli after listening to suggestive instructions for relaxing the body (i.e., 1 and 2 combined). Materials and methods. A special app was written for the Android operating system for the purpose of conducting this study and was installed on subjects' individual smartphones. The app included a screen touch test as a control for falling asleep. Data were analyzed from 63 subjects who were presented with the three types of sound stimuli noted above in a counterbalanced design. Results. Statistical analysis confirmed the hypothesis noted above that the SL depended on the type of sound stimulus (p < 0.05). Pairwise comparison of SL showed significant differences between stimuli (3) (1149 ± 113 sec) and (1) (1469 ± 89 sec) (p < 0.01). The SL for stimulus (2) had an intermediate value of 1269 ± 112 sec (differing from stimulus (1) at the level of a trend). Conclusion. The use of a sound background consisting of BB enhances the effect of suggestive instructions in improving sleep. However, the decisive role belongs to suggestion as a psychotherapeutic technique.

Abstract The Corneometer CM® 825 from Courage & Khazaka electronic GmbH is widely utilized in clinical efficacy testing of cosmetics. Assessing methodological variables is crucial for ensuring the reliability of the process. The aim of this study was to evaluate the operational and instrumental parameters of the Corneometer CM® 825 in the clinical assessment of skin hydration levels. Precision and accuracy of the measurements were assessed by measuring hydration levels on 10 participants in specific areas of the forearm and face. Three different skin conditions (dry, normal, and hydrated) resulting from the use or non-use of moisturizing cosmetics and a drying promoter were evaluated within 120 minutes of their application. The electrical capacitance method demonstrated good repeatability, with coefficients of variation mostly below 10%. However, higher variability was observed in inter-observer readings. The equipment exhibited high sensitivity and accurately discriminated the differences between hydrated and dry skin. Operational training and standardization of the methodology are essential to ensure accurate, reproducible, and reliable results in studies utilizing the Corneometer equipment for assessing skin hydration levels.

Jinxian Xu, Yang Zhang, Lujian Zhu, Shiyue Tang, Hanglu Xu, Dehe Zhang, Haijun Chen, Jing Zhou Department of Infectious Diseases, Zhejiang University Medical College Affiliated Jinhua Hospital, Jinhua, People’s Republic of ChinaCorrespondence: Jing Zhou, Department of Infectious Diseases, Zhejiang University Medical College Affiliated Jinhua Hospital, Jinhua, People’s Republic of China, Email zhoujing001011@sina.comBackground: Chronic hepatitis B (CHB) presents a global health challenge due to its potential to cause severe liver conditions such as hepatocellular carcinoma (HCC) and cirrhosis. Prior research has established a correlation between CHB infection with low-level viremia (LLV) and liver disease progression, such as increased HCC incidence. This study aims to investigate whether LLV during treatment with nucleos(t)ide analogs (NAs) contributes to the accelerated progression of liver fibrosis (LF).Methods: This retrospective cohort study at Jinhua Central Hospital focused on CHB patients undergone NA monotherapy for over 96 weeks. Patients were categorized into maintained virological response (MVR) and LLV groups based on hepatitis B virus (HBV) DNA levels. The study assessed LF using various markers and methods, including chitinase 3-like 1 protein (CHI3L1), aspartate aminotransferase-to-platelet ratio index (APRI), fibrosis-4 (FIB-4) score, and transient elastography.Results: Analysis was conducted on 92 CHB patients, categorized into LLV (n=42) and MVR (n=50) groups, following the exclusion of 101 patients for various reasons. Significant findings included lower baseline HBV DNA in MVR (< 20 IU/mL) compared to LLV (67.8 IU/mL, P< 0.001) and different AST/ALT ratios (LLV: 1.1, MVR: 1.36, P=0.011). LF was assessed using CHI3L1, FIB-4, and APRI, with LLV showing a higher baseline CHI3L1 (LLV:83.3 ng/mL vs MVR: 54.5 ng/mL, P=0.016) and scores compared to MVR, indicative of fibrosis. CHI3L1 levels in LLV were higher at baseline and weeks 48, 72, and 96 than MVR, with significance at baseline (P=0.038) and week 48 (P=0.034). Liver stiffness measurement (LSM) showed a time-dependent decline in both groups but no significant intergroup differences.Conclusion: Non-invasive monitoring of CHB patients who have received treatment indicates that LLV contributes to the progression of LF, necessitating proactive adjustment of antiviral treatment strategies.Keywords: chronic hepatitis B, low-level viremia, liver fibrosis, non-invasive methods, treatment strategies

ASTHMA , *SPUTUM , *NITRIC oxide , *AIRWAY (Anatomy) , *INFLAMMATION - Abstract
Recent advancements in asthma management include non-invasive methodologies such as sputum analysis, exhaled breath condensate (EBC), and fractional exhaled nitric oxide (FeNO). These techniques offer a means to assess airway inflammation, a critical feature of asthma, without invasive procedures. Sputum analysis provides detailed insights into airway inflammation patterns and cellular composition, guiding personalized treatment strategies. EBC collection, reflecting bronchoalveolar lining fluid composition, provides a non-invasive window into airway physiology. FeNO emerges as a pivotal biomarker, offering insights into eosinophilic airway inflammation and aiding in asthma diagnosis, treatment monitoring, and the prediction of exacerbation risks. Despite inherent limitations, each method offers valuable tools for a more comprehensive assessment of asthma. Combining these techniques with traditional methods like spirometry may lead to more personalized treatment plans and improved patient outcomes. Future research is crucial to refine protocols, validate biomarkers, and establish comprehensive guidelines in order to enhance asthma management with tailored therapeutic strategies and improved patient outcomes.

In the history of the German state, the world-wide economic crisis (1929-1939) probably also had an impact on the availability of inks. The research aimed to find out whether it is possible to discriminate between inks and determine the prevalence of ink manufacturers in a specific area, which, in statistical terms, could provide insight into the development of regional ink producers. The research covered selected inscriptions in ink written in a Diary from a small geographical area. Ink examination was carried out using non-invasive VIS-NIR and RS spectroscopic methods involving a statistical approach. The obtained results allowed effective discrimination of the inks and divided them into several groups. Research has shown that iron-gall inks from several ink manufacturers were used to prepare the entries in the Diary. It cannot be ruled out that the differences in individual inks resulted from technological changes in their production process. Additionally, the research revealed a multitude of entries made with iron-gall inks, which may testify to the development of small-scale production of iron-gall inks confined to one geographical area. This type of historical document may constitute a forgery in whole or in specific parts of the inscriptions executed to falsify significant facts, therefore it is an object of interest of forensic science. The non-invasive VIS-NIR and RS spectroscopic methods supported by statistical approach should continue to develop to become an alternative and reliable solution offering great potential in forensic examination of inks.

Determining precise boundaries and protective zones for historical and cultural objects enables their effective preservation. This article presents the framework for establishing protective zones around historical and cultural heritage sites existing in Ukraine, using the example of the Citadel defensive complex located in Lviv (Ukraine). It proposes general and detailed conceptual models for the combined application of remote and non-invasive methods for investigating historical and cultural heritage sites. It introduces the theory of integrating radar satellite imaging with ground-based georadar imaging. Additionally, it presents a software module that has been developed to analyze collected data on two-dimensional historical and cultural heritage objects, refine their boundaries, and establish protective zones around them. The result of the work is the determination of extremum points of vertical displacement on the territory of the historical and cultural heritage site "Lviv Citadel" in Ukraine using SAR, and the construction of a map of vertical displacements. A classification of these points was carried out, after which two of them were investigated using GPR for anomalies. Artifacts from World War II were discovered at each of these points. Using the developed software module, updated boundaries of the site were constructed, taking into account the underground artifacts and protective zones. [ABSTRACT FROM AUTHOR]

Introduction: Intensified hand hygiene measures were recommended for preventing the spread of SARS‐CoV‐2. However, these measures can lead to skin damage and the development of hand eczema, particularly among health professionals. Objectives: This pilot study aimed to evaluate the effects of repeated antiseptic use on healthy skin under controlled conditions and to assess the emollient use. Methods: Twelve healthy volunteers (nine females, age = 22.3 ± 2.8 years (mean ± SD), Fitzpatrick phototypes II and III) with no skin diseases were recruited. Antiseptic was applied daily for 3 weeks on the volar sides of forearms. Emollient cream was also applied daily. Skin assessments were performed using non‐invasive methods (transepidermal water loss—TEWL, skin hydration, erythema and melanin content). Results: Prolonged antiseptic use increased TEWL, decreased hydration and elevated erythema and melanin levels. Emollient cream significantly reduced TEWL and improved hydration on antiseptic‐treated sites, and also enhanced hydration on intact skin. Conclusions: Prolonged use of antiseptics can have adverse effects on the skin, including barrier disruption and inflammation. Emollient showed promise in improving skin hydration and reducing the damage caused by antiseptics. Further research with a larger sample is needed to confirm these findings and assess emollient efficacy during frequent antiseptic use. [ABSTRACT FROM AUTHOR]

Abstract The present study focuses on an icon known as the Panagia Valieriotissa at the Church of Saint Nicholas in Palodeia, Cyprus. The icon is unusual as it contains two depictions of the Virgin Mary and Child. The main aim of this study is to analyze the material characteristics of the icon and the relation of the two panels in order to determine if the icon belongs to a distinct category of paintings known as “composite icons” – icons consisting of two separate panels, one inserted into another. Icons of this unusual type, first described by Panayotis Vocotopoulos, appear to be quite numerous on Cyprus and date mostly to the sixteenth century. Results show that the icon can be included within this group, consequently enriching our knowledge on the materials, technologies, and techniques used in the creation of composite icons. Driven by art historical inquiries, the study’s methodological approach was based on the integration of digital imaging techniques with non-invasive and non-destructive material analyses pursued by the Andreas Pittas Art Characterization Laboratories (APAC Labs) of the Cyprus Institute. Spectroscopic techniques, digital microscopy and advanced digital imaging methods produced a broad range of data which were analyzed and interpreted from both an art-historical and a conservation perspective towards a better understanding of the materiality of the Palodeia icon and its subsequent history and use. The imaging and spectroscopic methods used provided new information on the materials and techniques used by the painters as well as on later undocumented episodes of restoration or repainting. Overall, the results showed that the icon indeed consists of two separate icons – a larger panel and a smaller, re-used icon inserted into the former. Moreover, some important distinctive features of the inset icon, invisible to the naked eye, reveal its possible previous use and dating. The study brought to light the great potential of non-invasive methods in the revealing and analysis of unknown aspects of composite icons, thus shedding light on this fascinating phenomenon, but it can also interest a broader group of researchers into the exciting new possibilities as well as the limitations of non-invasive methods for the study of works of art and heritage objects.

Relevance. Dental caries, according to World Health Organization, is one of the most common diseases in children throughout the world. In the absence of timely diagnosis and treatment, the carious process can affect not only the efficiency of chewing function, but also speech, smile and, as a consequence, psychosocial adaptation, as well as the quality of life of the child and family. Despite the fact that the etiological factors have been well known for many years, reducing the number of teeth affected by caries in children still remains an urgent task. This article is a review of information sources about the prevalence, etiology and integrated approach to the diagnosis, treatment and prevention of dental caries in children. The authors analyzed scientific data in the search engines PubMed, Google Scholar and eLibrary. Conclusion . Based on the literature review, a number of modern trends were identified that define a series of key hypotheses that summarize the accumulated material and confirm the prospects and relevance of the problem. The goal is to help clinicians recognize common patterns of caries in children and make appropriate decisions regarding the diagnosis, treatment and prevention of carious lesions, taking into account available methods, materials, knowledge, age and patient history. It is also important to create a comfortable and safe environment during the appointment, as unfamiliarity with a new physical interaction can provoke anxiety as a standard response to uncertainty, which often results in childhood dental phobia, contributing to behavioral resistance to return visits. In general, based on the analysis, we can conclude that the use of an integrated approach to diagnosis and treatment has great potential for achieving better results in working with dental patients of early and preschool age, the development and improvement of which should remain a priority to ensure more complete and effective treatment of children and maintaining their health in the long term.

Previously we proposed a new reconnaissance method for estimating the total abundance of small mammals in urban areas. The method includes placing plastic bottles with bait inside equal distances apart. In this research we examined two ways to improve the method: using bottles of smaller volume (0,25 liters instead of 0,5 liters) to increase the ergonomics and using opaque bottles to make them more attractive for animals. Bigger and smaller bottles with neck diameter of 38 mm were fastened in pairs which were set in a transect with a fi ve-meter spacing. The same was done with pairs of opaque and transparent bottles. A bait (rye bread with unrefi ned sunfl ower oil) was put into all the bottles. During the following days we recorded animals’ visits into the bottles. It was found out that there are no signifi cant diff erences in how often animals attend bottles of 0,25 liters and 0,5 liters, the same results were received for both transparent and opaque bottles. Thus, the simple method for estimating abundance of small mammals may be optimized by using smaller bottles, the colour of which is not important.

Multispectral devices have a huge potential to be utilized in biological, ecological, and agricultural studies, providing valuable information on plant structure and chemical composition. The aim of the study was to assess the reliability and sensitivity of the affordable leaf spectrometer PolyPen (PP) in comparison with the highly sensitive analytical device FieldSpec-4. Measurements at the leaf level were realized on a collection of 24 diverse field-grown wheat (Triticum sp. L.) genotypes in several growth phases during the regular growing season, focusing on whole spectral curves and a set of 41 spectral reflectance indices. As expected, the sensitive analytical device showed a higher capacity to capture genotypic variability and the ability to distinguish seasonal changes compared to a low-cost multispectral device. Nevertheless, the analysis of the data provided by low-cost sensors provided a group of parameters with good sensitivity, including reasonable correlations between the records of the two devices (r > 0.80). Based on the large obtained datasets, we can conclude that the application of a low-cost PP leaf spectrometer in plant and crop studies can be efficient, but the selection of parameters is crucial. Thus, the present study provides valuable information for users of affordable leaf spectrometers in fundamental and applied plant science.

Camera traps were deployed over 12 months (2022-2023) to examine the locomotor activity patterns of stone martens (Martes foina) in a Mediterranean habitat on the island of Dugi Otok, Croatia. Activity levels were calculated, and intersessional differences were tested. Trap rate was compared between seasons and three types of vegetation cover (open areas, dense vegetation areas and cultivated areas). Temperature and relative humidity data were collected using data loggers placed in the study area, and the correlation between the number of events was calculated. The differences between the independent events depending on the moon phase were tested. A total of 416 independent events involving stone martens were recorded. A unimodal locomotor activity pattern was found for the stone marten on this island, and the patterns remained relatively consistent, with predominantly nocturnal activity. Activity levels in winter were significantly higher than in other seasons. Trapping rates were lower in open areas. There was no significant correlation between the independent events and average temperature and relative humidity. The phases of the moon did not influence the number of independent events. This study identifies new perspectives on the locomotor activity of stone martens in a Mediterranean island habitat and serves as a starting point for further research. [ABSTRACT FROM AUTHOR]

- Abstract
The present study focuses on an icon known as the Panagia Valieriotissa at the Church of Saint Nicholas in Palodeia, Cyprus. The icon is unusual as it contains two depictions of the Virgin Mary and Child. The main aim of this study is to analyze the material characteristics of the icon and the relation of the two panels in order to determine if the icon belongs to a distinct category of paintings known as "composite icons" – icons consisting of two separate panels, one inserted into another. Icons of this unusual type, first described by Panayotis Vocotopoulos, appear to be quite numerous on Cyprus and date mostly to the sixteenth century. Results show that the icon can be included within this group, consequently enriching our knowledge on the materials, technologies, and techniques used in the creation of composite icons. Driven by art historical inquiries, the study's methodological approach was based on the integration of digital imaging techniques with non-invasive and non-destructive material analyses pursued by the Andreas Pittas Art Characterization Laboratories (APAC Labs) of the Cyprus Institute. Spectroscopic techniques, digital microscopy and advanced digital imaging methods produced a broad range of data which were analyzed and interpreted from both an art-historical and a conservation perspective towards a better understanding of the materiality of the Palodeia icon and its subsequent history and use. The imaging and spectroscopic methods used provided new information on the materials and techniques used by the painters as well as on later undocumented episodes of restoration or repainting. Overall, the results showed that the icon indeed consists of two separate icons – a larger panel and a smaller, re-used icon inserted into the former. Moreover, some important distinctive features of the inset icon, invisible to the naked eye, reveal its possible previous use and dating. The study brought to light the great potential of non-invasive methods in the revealing and analysis of unknown aspects of composite icons, thus shedding light on this fascinating phenomenon, but it can also interest a broader group of researchers into the exciting new possibilities as well as the limitations of non-invasive methods for the study of works of art and heritage objects.

Solid organ transplantation is a life‐saving intervention for individuals with end‐stage organ failure. Despite the effectiveness of immunosuppressive therapy, the risk of graft rejection persists in all viable transplants between individuals. The risk of rejection may vary depending on the degree of compatibility between the donor and recipient for both human leucocyte antigen (HLA) and non‐HLA gene‐encoded products. Monitoring the status of the allograft is a critical aspect of post‐transplant management, with invasive biopsies being the standard of care for detecting rejection. Non‐invasive biomarkers are increasingly being recognized as valuable tools for aiding in the detection of graft rejection, monitoring graft status and evaluating the efficacy of immunosuppressive therapy. Here, we focus on the importance of molecular biomarkers in solid organ transplantation and their potential role in clinical practice. Conventional molecular biomarkers used in transplantation include HLA typing, detection of anti‐HLA antibodies, killer cell immunoglobulin–like receptor genotypes, and anti‐MHC class 1–related chain A antibodies, which are important for assessing the compatibility of the donor and recipient. Emerging molecular biomarkers include the detection of donor‐derived cell‐free DNA, microRNAs (regulation of gene expression), exosomes (small vesicles secreted by cells), and kidney solid organ response test, in the recipient's blood for early signs of rejection. This review highlights the strengths and limitations of these molecular biomarkers and their potential role in improving transplant outcomes. [ABSTRACT FROM AUTHOR]

Breast cancer remains a prevalent health complication among the female population. Early and reliable detection in an individual is necessary for effective treatment. Thus, R&D into techniques for detection of breast cancer continues to the present. Noninvasive techniques include tactile examinations, electromagnetic scanning and checks for chemical markers. Invasive techniques include biopsies that extract tissue and liquid samples. These techniques have limitations and setbacks that are being addressed with supplementary or complementary techniques. Like the pre-existing techniques, these techniques also rely on comparison of data between control samples and afflicted patients to measure their reliability. Therefore, R&D efforts towards detection of breast cancer have resulted in incremental improvements on established methodologies. [ABSTRACT FROM AUTHOR]

Objective: The aim of this review was to evaluate the currently available scientific evidence on the efficacy of different methods as accelerators of tooth movement during orthodontic treatment: corticotomies, piezocision, micro-osteoperforations (MOP), photobiomodulation (LLLT and LED laser) and microvibrations. Search Methods: A comprehensive search was performed in the PubMed, Google Scholar, Scopus and Medline databases in May 2024. Selection Criteria: We selected randomized controlled trials based on acceleration of tooth movement during orthodontic treatment. Articles that were not randomized controlled trials (RCTs), were not published in the last ten years or corresponded to animal trials as well as those dealing with orthognathic surgery, distraction osteogenesis, electric currents, pulsed electric fields and pharmacological approaches were excluded. Results: Twenty-three studies were included in this review. All trials show accelerated tooth movement after low-level laser application, and seven studies support the efficacy of surgically assisted orthodontic treatment with corticotomies, piezocision or MOP. No article indicates statistically significant differences between the application of microvibration during orthodontic treatment and conventional treatment. No negative effects on the periodontium, loss of dental vitality or serious root resorption were reported in any publication, except in a study carried out with MOP (with an increase in root resorption). Conclusions: There is some evidence that low-level laser therapy and surgical methods are effective techniques in accelerating tooth movement during orthodontic treatment, while the evidence is very weak for vibration.

Determining precise boundaries and protective zones for historical and cultural objects enables their effective preservation. This article presents the framework for establishing protective zones around historical and cultural heritage sites existing in Ukraine, using the example of the Citadel defensive complex located in Lviv (Ukraine). It proposes general and detailed conceptual models for the combined application of remote and non-invasive methods for investigating historical and cultural heritage sites. It introduces the theory of integrating radar satellite imaging with ground-based georadar imaging. Additionally, it presents a software module that has been developed to analyze collected data on two-dimensional historical and cultural heritage objects, refine their boundaries, and establish protective zones around them. The result of the work is the determination of extremum points of vertical displacement on the territory of the historical and cultural heritage site “Lviv Citadel” in Ukraine using SAR, and the construction of a map of vertical displacements. A classification of these points was carried out, after which two of them were investigated using GPR for anomalies. Artifacts from World War II were discovered at each of these points. Using the developed software module, updated boundaries of the site were constructed, taking into account the underground artifacts and protective zones.

The application of faecal DNA in genetic studies of wild populations minimises disturbances to their normal behaviours and body integrity. Here, I present an analysis of a metagenomic dataset generated from the faecal DNA of several specimens of the estuarine pipefish, Syngnathus watermeyeri, to simultaneously assemble the mitogenomes of the predator and its main prey species, the copepod Pseudodiaptomus hessei. The mitogenomes of the pipefish and the copepod were successfully reconstructed using a combination of short seed extension and denovo metagenomic assembly. Nucleotide blast searches of the circular contigs, mitogenome annotations, and Bayesian phylogenetic analyses confirm the completeness and correct taxonomic placements of the two mitogenomes. In addition, heteroplasmy detection and Pool-Seq variant calling quantified the level of genetic diversity in the sequences that formed these assemblies. These can be used as a first step to non-invasively survey genetic diversity in these populations.

Background: Non-invasive assessment methods to assess liver fibrosis are important tools where FibroScan or liver biopsy is not accessible. This study aims to assess the efficacy and performance of the fibrosis index based on four factors (FIB-4) and aspartate transaminase-to-platelet ratio index (APRI) to evaluate liver fibrosis against FibroScan for the stages of liver fibrosis in obese type-2 diabetic patients. Methods: This was a cross-sectional study conducted in a tertiary care center in Bihar, India, and the patients were enrolled within two years. During the study period, 80 patients with a confirmed diagnosis of type-2 diabetes mellitus were selected. Laboratory blood testing and FibroScan were performed in all patients with T2DM. APRI and FIB-4 were calculated using a standard formula involving laboratory parameters. Result: The performance of FIB-4 scores is nearly similar to APRI, with the area under the curve (AUC) 0.753, (95% CI) (0.711-0.795) (p

This study aimed to evaluate whether obesity impairs cardiac autonomic modulation after maximal cardiopulmonary exercise testing (CPET). Thirty-six men (aged 18 to 30 years) were divided into two groups: normal-weight (n = 20, 21.31 ± 1.57 kg m−2) and obese (n = 16, 34.12 ± 2.46 kg m−2). Heart rate variability (HRV) indices - RMSSD (root mean square of successive RRi differences), SDNN (standard deviation of normal-to-normal RRi), high frequency (HF), low frequency (LF) and LF/HF ratio were evaluated at baseline and during 90 min of recovery after a maximal CPET. There were no differences (P > 0.05) between groups in short-term nor in long-term recovery for heart rate (HR) and HRV indices. Regardless of the group (main effect of time, P < 0.001, Pr = 1.00), the HR remained higher up to 60 min of recovery, and the lnRMSSD and lnSDNN remained lower up to 45 and 30 min of recovery post-exercise in relation to baseline, respectively. Both lnLF, and LF/HF ratio, remained higher up to 45 min of recovery in relation to baseline, and lnHF, did not return to baseline until 90 min post-exercise (main effect of time, P < 0.001, Pr = 0.94 to 1.00). In young men, time-course of cardiac autonomic recovery post-exercise was not affected through obesity condition. This information can enable the use of non-pharmacological strategies (i. e., physical exercise or a healthy eating lifestyle) for body fat reduction and the early prevention of cardiac autonomic dysfunction, and consequent decreasing in cardiovascular risks.

The development of methods for measuring blood pressure (BP) in newborns and small children has a rich history. Methods for BP measuring in adults had to be adapted to this age group. For measuring BP in direct invasive way, a suitable approach had to be found to access the arterial circulation through the umbilical and later radialis artery. Currently, results obtained from direct invasive BP measurement are considered the “gold standard”. The development of non-invasive methods for BP measuring in newborns and children began with the use of von Basch's sphygmomanometer (1880). In 1899, Gustav Gärtner constructed the device, which was the basis for the flush method. After the discovery of the palpation and auscultation methods, these methods were also used for BP measurement in newborns and children, however, the BP values obtained in these ways were typically underestimated using excessively wide cuffs. From the auscultation method, methods utilizing ultrasound and infrasound to detect arterial wall movement and blood flow were later developed. The oscillometric method for BP measurement was introduced by E. J. Marey so early as in 1876. In 1912, P. Balard used the oscillometric technique to measure blood pressure in a large group of newborns. Through different types of oscillometers using various methods for detecting vascular oscillations (such as xylol method, impedance and volume plethysmography, etc.), the development has continued to assessment of vascular oscillations by modern sensor technology and software. For continuous non-invasive blood pressure measurement, the volume-clamp method, first described by Jan Peňáz in 1968, was developed. After modification for use in newborns, application of the cuff to the wrist instead of the finger, it is primarily used in clinical physiological studies to evaluate beat-to-beat BP and heart rate pressure variability, such as in the determination of the baroreflex sensitivity.

Long COVID-19 patients show systemic inflammation and persistent symptoms such as fatigue and malaise, profoundly affecting their quality of life. Since improving oxygenation can oppose inflammation at multiple tissue levels, we hypothesized that hyperbaric oxygen therapy (HBOT) could arrest inflammation progression and thus relieve symptoms of COVID-19. We evaluated oxy-inflammation biomarkers in long COVID-19 subjects treated with HBOT and monitored with non-invasive methods. Five subjects (two athletes and three patients with other comorbidities) were assigned to receive HBOT: 100% inspired O
2 at 2.4 ATA in a multiplace hyperbaric chamber for 90 min (three athletes: 15 HBOT × 5 days/wk for 3 weeks; two patients affected by Idiopathic Sudden Sensorineural Hearing Loss: 30 HBOT × 5 days/wk for 6 weeks; and one patient with osteomyelitis: 30 HBOT × 5 days/wk for week for 6 weeks and, after a 30-day break, followed by a second cycle of 20 HBOT). Using saliva and/or urine samples, reactive oxygen species (ROS), antioxidant capacity, cytokines, lipids peroxidation, DNA damage, and renal status were assessed at T1_pre (basal level) and at T2_pre (basal level after treatment), and the results showed attenuated ROS production, lipid peroxidation, DNA damage, NO metabolites, and inflammation biomarker levels, especially in the athletes post-treatment. Thus, HBOT may represent an alternative non-invasive method for treating long COVID-19-induced long-lasting manifestations of oxy-inflammation. [ABSTRACT FROM AUTHOR]- Published

Chronic liver injury and subsequent liver fibrosis are usually a slow process without any specific or no clinical signs, resulting in pathological conditions with a poor chance of improvement through medical and surgical treatment, which if not promptly recognized, often lead to a liver transplant as the only therapeutic option. On the other hand, screening and follow-up are hard to establish in large populations using regularly invasive methods such as biopsies and other expensive diagnostic tools due to cost and a lack of adequate specificity and sensibility. In the last few years, a large variety of serological and radiological tests have been proposed to assess liver fibrosis. In this review, we will consider the most commonly used scores to evaluate liver fibrosis, with a special focus on the NAFLD pathogenesis. We will try to answer the question: can we rely on them?

Simple Summary: This study explores the use of alternative and non-harmful methods for monitoring endangered Mediterranean trout in small intermittent streams. Specifically, two visual survey techniques were compared: a visual survey from streambanks and an underwater visual survey using underwater cameras. The main objective was to assess the effectiveness of detecting patterns in fish occupancy in relation to a set of environmental factors. The comparison revealed that underwater camera surveys performed similarity to visual surveys from streambanks during low-flow regimes. However, visual surveys from streambanks were less effective during the highest flow regimes. The volume of pools and the percentage cover of submerged macrophytes were found to be significant environmental variables affecting fish detection probability using underwater cameras. On the other hand, the analysis of data from visual observations from streambanks indicated a clear impact of high turbulence rates on pool occupancy. In conclusion, these findings demonstrate the utility of visual methods in describing the occupancy patterns of Mediterranean trout in small streams. Monitoring the conservation status of endangered freshwater fish using less invasive methods poses challenges for ecologists and conservationists. Visual surveys have been proposed as an alternative to electrofishing, which is a standard methodology that can cause injuries, physiological stress and post-release mortality in organisms. To test the efficacy of visual methods, a study was conducted in an intermittent stream of Sardinia (Italy). Two visual methods were employed: a visual survey from streambanks (VSS) and an underwater visual survey (UVS) using cameras. The aims of this study were (1) to compare the effectiveness of these methods in detecting patch occupancy patterns and (2) to investigate the effect of environmental variables on the detection probability of Mediterranean native trout. Environmental variables characterizing pool habitats were recorded, and generalized linear models (GLMs) were employed to assess the correlation between these variables and trout presence/absence. GLM analysis revealed that UVS had higher detection probability with larger pool volume, whereas submerged macrophytes negatively affected detection probability. Detection from streambanks (VVS) was negatively affected by a high turbulence rate. In conclusion, our study suggests the utility of visual methods to describe patterns of patch occupancy of Mediterranean trout. However, methods can be differently affected by environmental variables. Therefore, monitoring programs using these methods should consider these factors to ensure a reliable description of within-stream trout distribution in intermittent streams. [ABSTRACT FROM AUTHOR]

Along the coast of the southeast of the Iberian Peninsula, there are numerous remains linked to the manufacture of purple dyes. This study focuses on the site of Torregarcía (Almería, Spain), located in the Cabo de Gata-Níjar Natural Park, a protected coastal area of particular ecological interest. Torregarcía was initially excavated during 1980s and was identified as a Roman salting factory where the complementary activity of dyeing was also practised. Despite its importance, it has gone unnoticed in the historiography of the last three decades and has never been the subject of dedicated scientific publication. The investigations presented in this book have been carried out using non-invasive prospecting techniques, such as ground-penetrating radar (GPR), and have revealed the importance of the exploitation of purple dye as the main site activity. More complex installations associated with the excavated structures and a large shell pit are also described. Alongside these, other buildings and shells have also been documented along the coastline of this site. All of this forms what we call the "purple landscape" in the southeast of the peninsular coast, which allows the Natural Park to show archaeological heritage beyond any excavations carried out to date.

ObjectivePatients with nonalcoholic steatohepatitis (NASH) are at risk for developing cirrhosis and hepatic cancer. Currently, the definitive gold-standard method of diagnosing NASH is a liver biopsy, an invasive and costly method. Our objective was to compare three non-invasive methods of identifying NASH by using data on 10,007 subjects from NHANES III (1988-1994) to determine the prevalence and variables associated with NASH, as defined by each non-invasive method.MethodsWe used ultrasound data to identify subjects with moderate-to-severe hepatic steatosis, of whom we identified the NASH population using either the HAIR score, the NASH liver fat score, or the Gholam score, each of which had been validated with liver biopsy. We performed multinomial logistic regression to compare each NASH population to the normal population (those with no-to-mild hepatic steatosis).ResultsWe identified 1136 (9.5%) subjects as having NASH by at least one method and 219 (1.8%) were identified by all 3 methods. Independent of the non-invasive method used, Mexican-Americans (MA) had the highest prevalence of NASH. All three methods identified significant risk factors for NASH (p

Being carriers of information, historical documents have an important role in the modern world. Unfortunately, they are also the object of criminal activity. For centuries, various types of ink have been used to produce documents. Although inks are not the only writing material in use, from a forensic point of view, the problem consists in distinguishing one type of ink from another, and more specifically, the compatibility or incompatibility of the components of two or more inks found on one document or multiple documents. Samples of ink writing dating back to 1889-1950 were examined with the aim of researching by non-invasive spectroscopic methods whether, over the years, any changes in the production technology of iron-gall inks have resulted in significant changes in their reflectance and Raman spectra. The research showed that the production technology of iron-gall inks has not changed significantly, and, in addition, contemporary methods do not differ significantly from those used in the Middle Ages. The spectroscopic methods used in the research gave positive results because they made it possible to distinguish inks by dividing them into groups. The diversity of the distinguished groups of inks was caused by the addition of different synthetic dyes during production. The research on iron-gall inks showed the need for further continuation involving a much larger reference group and the need to look for differences in ink from one place, one geographic location, and made at similar times.

This study aimed to characterise the specific phenotypic responses and the sensitivity of photosynthetic parameters to progressive drought in modern wheat genotypes. In pot experiments, we tested eight wheat genotypes (Triticum sp.) that differed in ploidy level and country of origin. Water stress was simulated by the restriction of irrigation, which led to a decreased leaf relative water content of up to 70%. During gradual dehydration, changes in the structure and function of photosystem II (PSII) were analysed using the fluorescence parameters derived from fast fluorescence kinetics (OJIP transient). The results indicated that a group of JIP test-based parameters demonstrated sensitivity to drought, including genotype-specific responses. Severe drought stress led to a decrease in the photochemical efficiency of PSII (Fv/Fm), a reduction in the number of active PSII reaction centers (RC/ABS) and a decrease in parameters, indicating overall photochemical performance at the PSII level (performance indices PIabs and PItot). These findings demonstrate that the approaches used in our experiments were useful and reliable in monitoring the physiological responses of individual varieties of wheat exposed to stress conditions, and they have application potential as selection criteria in crop breeding. The contribution of the high-temperature effects on the photochemical responses under water deficit conditions is also discussed.

The 2019–2020 Australian bushfires were unprecedented both in extent and severity, impacting wildlife through direct mortality as well as habitat damage. More than 10% of koala habitat is estimated to have been affected by fires. Estimating the number of koalas lost is crucial to assess koala conservation status and to determine the appropriate management actions required. However, this is not a trivial task, as accurate data on koala distribution and population density before the fires is patchy. Acknowledging this weakness, we sought to estimate fire impact on koalas at specific sites, by comparing habitat areas affected by the fire with habitat areas that were unaffected by the fire, pairing closely related study sites (based on geography and vegetation). To compare koala density, we deployed two koala detection methods; drone‐acquired thermal imagery and detection dogs coupled with genetic fingerprinting, in four fire‐affected sites paired with four control sites in New South Wales and Queensland. Through drone surveys, we detected 140 koalas in 5,240 ha in New South Wales. The detection dogs found 144 scat samples corresponding to 79 unique koalas in 77 ha of transects in Queensland. Our preliminary results show many koalas were still present in fire‐affected areas after the 2019–2020 bushfire season. Koala density was 24 to 71% lower in fire‐affected sites compared with control sites in three of the habitat pairs, whereas unexpectedly, in the fourth pair, we observed a 317% higher koala density in the fire‐affected site. This underlined that koalas can be present in fire‐affected areas and that monitoring their health could be critical for months after the fires. [ABSTRACT FROM AUTHOR]

- Abstract
Non-invasive methods are important to the field of conservation physiology to reduce negative effects on organisms being studied. Glucocorticoid (GC) hormones are often used to assess health of individuals, but collection methods can be invasive. Many amphibians are imperiled worldwide, and saliva is a non- or semi-invasive matrix to measure GCs that has been partially validated for only four amphibian species. Validation ensures that assays are reliable and can detect changes in saliva corticosterone (sCORT) after exposure to stressors, but it is also necessary to ensure sCORT concentrations are correlated with plasma concentrations. To help validate the use of saliva in assessing CORT responses in amphibians, we captured uniquely marked Columbia spotted frogs (Rana luteiventris) on sequential days and collected baseline and stress-induced (after handling) samples. For a subset of individuals, we collected and quantified CORT in both saliva and blood samples, which have not been compared for amphibians. We tested several aspects of CORT responses and, by collecting across separate days, measured repeatability of CORT responses across days. We also evaluated whether methods common to amphibian conservation, such as handling alone or handling, clipping a toe and tagging elevated sCORT. Similar to previous studies, we show that sCORT is reliable concerning parallelism, recovery, precision and sensitivity. sCORT was weakly correlated with plasma CORT (R
2 = 0.21), and we detected elevations in sCORT after handling, demonstrating biological validation. Toe clipping and tagging did not increase sCORT over handling alone, but repeated handling elevated sCORT for ~72 hours. However, sCORT responses were highly variable and repeatability was low within individuals and among capture sessions, contrary to previous studies with urinary and waterborne CORT. sCORT is a semi-invasive and rapid technique that could be useful to assess effects of anthropogenic change and conservation efforts, but will require careful study design and future validation.

ZOONOSES - Abstract
A small proportion of disease surveillance programs target environment compartment, and in the EU these are restricted to few countries. The present report is composed of two literature reviews (i) on the main existing structures and systematic/academic initiatives for surveillance in the EU for zoonoses in the environment, and (ii) on the methods for pathogen surveillance in the environment. Concerning (i), it is noteworthy that the most frequently reported objective was to evaluate control and eradication strategies and following trends of zoonosis. However, detecting new pathogens or unusual epidemiological events were scarcely reported as objectives, as well as demonstrating freedom from a particular pathogen, despite the big potential that environmental sampling and testing techniques have recently demonstrated for these purposes. Few of the pathogens prioritised by EFSA were represented in this literature review, indicating the potential of environmental techniques to be applied to a larger extent to detect relevant transboundary and (re)emergent zoonoses. The preferred environmental sample was water, followed by biological material (included faecal material) and vectors (mosquitoes). To a much lesser extent, soil, and other matrices were used. Regarding (ii) the pathogen detection and identification methods were divided into: conventional (culture and biochemistry‐based, and immunology‐based); molecular methods (nucleic acid‐based methods); biosensor‐based (new) and others. A large percentage of available assays for the detection and surveillance of pathogens in the environment focuses on hazards that are not among those pre‐selected by EFSA. Therefore, there is a need for development of new, untested, methods for surveillance of listed pathogens of higher epidemiological importance. Less disturbed areas, natural and wild environments are less covered by environmental sampling techniques than urban and farm environments and should therefore receive higher attention since they may hold undiscovered and potentially epidemiologically significant hazards and hosts. In general, molecular methods, namely the nucleic‐acid based methods, are the ones more commonly and widely used for pathogen detection in environmental samples, and can be developed for virtually any organism, given a sufficient effort to identify specific DNA/RNA sequences unique to the target organism. The usefulness and appropriateness of different environmental matrices for detecting specific pathogens or for specific purposes are discussed and recommendations are provided. [ABSTRACT FROM AUTHOR]

Recent findings of archaeological research in the Vathy gulf area, Astypalaia Island, indicate its continuous habitation since prehistoric times, most importantly in the transitional period from the Final Neolithic to the Early Bronze Age (late 4th/early 3rd millennium BC). The evaluation of the prehistoric stone artefacts from Vathy using non-invasive analytical methods (Near Infrared Spectroscopy—NIR), in combination with the mineral-petrographic characterization of the main lithological formations of the island, is expected to provide important information about raw material procurement and possible exchange networks. The geological study of the island combined with the analytical methods applied to the archaeological artefacts and the geological samples led to the identification of both local and allogenic materials. The possible locations of raw material sources were established and the origin of allogenic materials was estimated. The stone artefacts made of local geo-materials consist mainly of calcitic sandstone, shale, marl, and limestone/marble, comprising the largest part of the lithological formations of the island, as well as pumice and volcanic rocks of varying chemical composition. By means of a portable microscope and NIR spectroscopy, we were further able to identify allogenic geo-materials including chalcedony, mica schist, bauxite and meta-bauxite, steatite, and paragonite. Based on the mineralogical and petrographic characterization of the stone artefacts, a first attempt is made to evaluate the possible raw material sources and to identify potential intra-island modes of stone exploitation.

Data concerning hepatitis C virus (HCV) treatment using direct-acting agents (DAAs) post liver transplantation (LT) remains scarce in low- and average-income countries. To evaluate the safety and efficacy of post-LT HCV treatment using DAAs in Rio de Janeiro (Brazil), and to assess the course of hepatic biomarkers after sustained virological response (SVR). Data from LT recipients with recurrent HCV treated using DAAs was retrospectively analyzed. HCV was defined by detectable HCV-RNA with elevated aminotransferases and/or histological signs of infection on liver biopsy post LT. SVR was defined as undetectable HCV-RNA 12 weeks after the end of treatment. Aspartate-to-Platelet Ratio Index (APRI) and Fibrosis-4 score (FIB-4) were calculated before treatment and after SVR. Results: 116 patients (63% male, median age 62 years, 75% genotype 1 and 62% with hepatocellular carcinoma [HCC] prior to LT) were included. Cirrhosis was identified in the allograft of 21 subjects (18%). The overall SVR was 96.6% without differences in SVR proportion according to clinical/demographic characteristics, genotype or presence of cirrhosis. SVR rates were similar in individuals with and without HCC pre-LT (95.8% [95% CI: 87.6–98.7] vs. 97.7% [95% CI: 85.0–99.7%], p = 0.588). No serious adverse events were observed and the use of ribavirin was associated with at least one adverse event (OR = 8.71 [95% CI: 3.17–23.99]). SVR was associated with regression of APRI (OR = 26.00 [95% CI 4.27–1065.94]) and FIB-4 (OR = 15.00 [95% CI: 2.30–631.47]). Post-LT HCV treatment with DAAs was safe and effective and associated with a significant decrease in hepatic biomarker levels after SVR. [ABSTRACT FROM AUTHOR]
