Abstract
Rationale and objectives Imaging plays a key role in Slipped Capital Femoral Epiphysis diagnosis and severity assessment. In the last two decades, signs and measurements emerged in literature showed potential to help in SCFE diagnosis and tailoring treatment. The purpose of this review is to collect and discuss new imaging signs, measurements, and techniques according to investigations published after 2000 to improve SCFE diagnosis. Material and methods The PubMed, Scopus, and Science Direct databases were used to search for relevant articles related to imaging in SCFE diagnosis from January 2000 to March 2023. Article selection and review was performed by two board-certified radiologists). Article quality assessment were conducted by authors using QUADAS-2 and SANRA evaluation tools. Results The research resulted in a total of 2577 articles. After duplicates removal and abstract analysis, 28 articles were finally selected for full-text analysis. Seventeen articles were focused on Radiographs, 6 on CT, 1 on both Radiographs and CT, 4 on MRI. No study focused on ultrasound was selected. Conclusions Use of modified Klein's line and S-sign may improve radiographs accuracy in daily routine. Lucency sign may help in early diagnosis on radiographs. Preoperative CT may be useful in planning a tailored treatment predicting SCFE severity and instability. MRI is the most accurate modality to diagnose SCFE at early stage. Nevertheless, it cannot be used to predict the risk of contralateral SCFE. Risk prediction can be assessed with radiographs, using a new rapid mOBS. Further investigation and validation of these sign is needed.

Abstract
van Neck-Odelberg disease, a condition involving the ischiopubic synchondrosis in children, is a commonly encountered but poorly known ailment, which is now considered a normal variant. Symptoms can include pain, discomfort, and fever, leading to van Neck-Odelberg disease often being discovered in the context of patients presenting with non-specific clinical manifestations. In this essay, we describe what is currently known about van Neck-Odelberg disease and illustrate the condition using images acquired from multiple patients, with some using multiple imaging techniques from the same patients. Awareness of van Neck-Odelberg disease is essential for radiologists who are involved in the treatment of children, as well as for paediatricians, to prevent misdiagnosis and unnecessary invasive procedures for what is a benign and self-resolving condition.

Abstract
BACKGROUND & AIMS β-blockers reduce hepatic venous pressure gradient (HVPG) by decreasing portal inflow, with no reduction in intrahepatic vascular resistance. 5-Methyltetrahydrofolate (5-MTHF) can prevent oxidative loss of tetrahydrobiopterin (BH4), a cofactor for endothelial nitric oxide synthase coupling. It also converts homocysteine (tHcy) into methionine and enables the degradation of asymmetric dimethylarginine (ADMA), an inhibitor of endothelial nitric oxide synthase. The aim of this study was to evaluate the effects of 5-MTHF in combination with propranolol on HVPG and nitric oxide bioavailability markers in patients with cirrhosis and portal hypertension. METHOD Sixty patients with cirrhosis and HVPG ≥12 mmHg were randomized 1:1 to receive treatment with 5-MTHF+propranolol or placebo+propranolol for 90 days under double-blind conditions. HVPG and markers of nitric oxide bioavailability (BH4, ADMA and tHcy) were measured again at the end of treatment. RESULTS Groups were similar in terms of baseline clinical and hemodynamic data and nitric oxide bioavailability markers. HVPG decreased in both groups, but the magnitude of the change was significantly greater in the group treated with 5-MTHF+propranolol compared to placebo+propranolol (percentage decrease, 20 [29-9] vs. 12.5 [22-0], p = 0.028), without differences in hepatic blood flow. At the end of treatment, 5-MTHF+propranolol (vs. placebo+propranolol) was associated with higher BH4 (1,101.4 ± 1,413.3 vs. 517.1 ± 242.8 pg/ml, p <0.001), lower ADMA (109.3 ± 52.7 vs. 139.9 ± 46.7 μmol/L, p = 0.027) and lower tHcy (μmol/L, 11.0 ± 4.6 vs. 15.4 ± 7.2 μmol/L, p = 0.010) plasma levels. CONCLUSION In patients with cirrhosis and portal hypertension, 5-MTHF administration significantly enhanced the HVPG reduction achieved with propranolol. This effect appears to be mediated by improved nitric oxide bioavailability in the hepatic microcirculation. CLINICAL TRIAL EUDRACT NUMBER 2014-002018-21. IMPACT AND IMPLICATIONS Currently, the pharmacological prevention of cirrhosis complications due to portal hypertension, such as esophageal varices rupture, is based on the use of β-blockers, but some patients still present with acute variceal bleeding, mainly due to an insufficient reduction of portal pressure. In this study, we sought to demonstrate that the addition of folic acid to β-blockers is more effective in reducing portal pressure than β-blockers alone. This finding could represent the basis for validation studies in larger cohorts, which could impact the future prophylactic management of variceal bleeding in cirrhosis. Enhancing the benefit of β-blockers with a safe, accessible, cost-effective drug could improve clinical outcomes in cirrhosis, which in turn could translate into a reduction in the rates and costs of hospitalization, and ultimately into improved survival.

Abstract
Bile acids (BAs), endogenous acidic steroids synthetized from cholesterol in the liver, play a key role in the gut-liver axis physiopathology, including in hepatotoxicity, intestinal inflammatory processes, and cholesterol homeostasis. Faecal Oxo-BAs, relatively stable intermediates of oxidation/epimerization reactions of the BA hydroxyls, could be relevant to investigating the crosstalk in the liver-gut axis and the relationship between diseases and alterations in microbiota composition. A paucity of information currently exists on faecal BA profiles in dogs with and without chronic inflammatory enteropathy (CIE). Comprehensive assessment of 31 molecules among faecal BAs and related microbiota metabolites was conducted with high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS). Odds ratios (ORs) for associations of BAs with CIE were estimated using logistic regression. Principal component analysis was performed to find differences between the control and pathological dogs. Higher levels of primary BAs and muricholic acids, and lower levels of secondary BAs were found in pathological dogs. Higher concentrations in faecal oxo-metabolites were associated with the absence of CIE (OR < 1). This study shows a marked difference in faecal BA profiles between dogs with and without CIE. Further research will be needed to better understand the role of oxo-BAs and muricholic acids in CIE dogs.

Abstract
The release of hazardous chemicals into aquatic environments has long been a known problem, but its full impact has only recently been realized. This study presents a validated liquid chromatography-mass spectrometry (HPLC-MS/MS) method for detecting pharmaceutical and pesticide residues in mussels (Mytilus galloprovincialis). An innovative MS-compatible extraction method was developed and validated, demonstrating successful recovery rates for analytes at three different concentration levels (25-95%). The method detected the target analytes at ng/g concentrations with high accuracy (-7% to 11%) and low relative standard deviation (<10%) for both intra-day and inter-day analyses. After validation, the method was applied to mussel samples collected from a commercial farm near Senigallia, Adriatic Sea, detecting different contaminants in the range of 2-40 ng/g (dry weight). The study provides a valuable tool for investigating the potential threats posed by diverse contaminant classes with high annual tonnage, including analytes with known persistence and/or illegal status.

Abstract
Atherosclerosis and atherosclerotic-related cardiovascular diseases (ASCVD) are characterized by high serum levels of low-density lipoprotein cholesterol (LDL-C) that can promote the generation of reactive oxygen species (ROS). To answer the need for better LDL-C control in individuals at high and very high risk for CVD, a new injectable innovative family of lipid-lowering (LL) monoclonal antibodies against the protein convertase subtilisin/kexin type 9 (PCSK9) has been approved. However, the effect of these drugs on vascular function, such as ROS generation and arterial stiffness, has not already been extensively described. In this report, we present data from 18 males with high to very high CV risk undergoing LL treatment (LLT) with either statin and ezetimibe or ezetimibe monotherapy, who experienced, after a 2-month treatment with Evolocumab, a significant improvement in blood pressure (BP)-adjusted carotid–femoral pulse wave velocity (cfPWV) (p-value = 0.0005 in the whole cohort, p-value = 0.0046 in the sub-cohort undergoing background LLT with statin and ezetimibe, p-value = 0.015 in the sub-cohort undergoing background LLT with ezetimibe monotherapy), which was significantly associated with a decrease in freshly isolated leukocytes (PBMCS)-derived H2O2 production (p-value = 0.004, p-value = 0.02 and p-value = 0.05, respectively, in the whole cohort, in the statin + ezetimibe sub-cohort, and the ezetimibe sub-cohort). Our observations support the role of systemic oxidative stress in atherosclerosis and give a further rationale for using Evolocumab also for its effect in vascular disorders linked to oxidative processes.

Abstract
Colorectal cancer (CRC) ranks as the second among the causes of tumor death worldwide, with an estimation of 1.9 million new cases in 2020 and more than 900,000 deaths. This rate might increase by 60% over the next 10 years. These data are unacceptable considering that CRC could be successfully treated if diagnosed in the early stages. A high-fat diet promotes the hepatic synthesis of bile acids (BAs) increasing their delivery to the colonic lumen and numerous scientific reports correlate BAs, especially secondary BAs, with CRC incidence. We reviewed the physicochemical and biological characteristics of BAs, focusing on the major pathways involved in CRC risk and progression. We specifically pointed out the role of BAs as signaling molecules and the tangled relationships among their nuclear and membrane receptors with the big bang of molecular and cellular events that trigger CRC occurrence.

Abstract
To accurately diagnose COVID-19 infection and its time-dependent progression, the rapid, sensitive, and noninvasive determination of immunoglobulins A specific to SARS-CoV-2 (IgA) in saliva and serum is needed to complement tests that detect immunoglobulins G and M. We have developed a dual optical/chemiluminescence format of a lateral flow immunoassay (LFIA) immunosensor for IgA in serum and saliva. A recombinant nucleocapsid antigen specifically captures SARS-CoV-2 antibodies in patient specimens. A labelled anti-human IgA reveals the bound IgA fraction. A dual colorimetric and chemiluminescence detection enables the affordable and ultrasensitive determination of IgA to SARS-CoV-2. Specifically, a simple smartphone-camera-based device measures the colour signal provided by nanogold-labelled anti-human IgA. For the ultrasensitive chemiluminescence transduction, we used a contact imaging portable device based on cooled CCD, and measured the light signal resulting from the reaction of the HRP-labelled anti-human IgA with a H2O2/luminol/enhancers substrate. A total of 25 serum and 9 saliva samples from infected and/or recovered individuals were analysed by the colorimetric LFIA, which was sensitive and reproducible enough for the semi-quantification of IgA in subjects with a strong serological response and in the early stage of COVID-19 infection. Switching to CL detection, the same immunosensor exhibited higher detection capability, revealing the presence of salivary IgA in infected individuals. For the patients included in the study (n = 4), the level of salivary IgA correlated with the time elapsed from diagnosis and with the severity of the disease. This IgA-LFIA immunosensor could be useful for noninvasively monitoring early immune responses to COVID-19 and for investigating the diagnostic/prognostic utility of salivary IgA in the context of large-scale screening to assess the efficacy of SARS-CoV-2 vaccines.

Abstract
Lactic acid bacteria (LAB) “fermentates” confer a beneficial effect on intestinal function. However, the ability of new fermentations to improve LAB broth activity in preventing pathogen-induced intestinal inflammation and barrier dysfunction has not yet been studied. The objective of this study was to determine if broths of LAB fermented with Eruca sativa or Barbarea verna seed extracts prevent gut barrier dysfunction and interleukin-8 (CXCL8) release in vitro in human intestinal Caco-2 cells infected with enterohemorrhagic Escherichia coli (EHEC) O157:H7. LAB broths were assayed for their effects on EHEC growth and on Caco-2 viability; thereafter, their biological properties were analysed in a co-culture system consisting of EHEC and Caco-2 cells. Caco-2 cells infected with EHEC significantly increased CXCL8 release, and decreased Trans-Epithelial Electrical Resistance (TEER), a barrier-integrity marker. Notably, when Caco-2 cells were treated with LAB broth enriched with E. sativa seed extract and thereafter infected, both CXCL8 expression and epithelial dysfunction reduced compared to in untreated cells. These results underline the beneficial effect of broths from LAB fermented with E. sativa seed extracts in gut barrier and inflammation after EHEC infection and reveal that these LAB broths can be used as functional bioactive compounds to regulate intestinal function.

Abstract
Background CPFA is an extracorporeal treatment used in severe sepsis to remove circulating proinflammatory cytokines. Limited evidence exists on the effectiveness of bilirubin adsorption by the hydrophobic styrenic resin, the distinctive part of CPFA. The aim of this study is to validate CPFA effectiveness in liver detoxification. Methods In this prospective observational study, we enrolled patients with acute or acute-on-chronic liver failure (serum total bilirubin > 20 mg/dL or MELD Score > 20) hospitalized from June 2013 to November 2017. CPFA was performed using the Lynda (Bellco/MedTronic, Mirandola, Italy) or the Amplya (Bellco/MedTronic, Mirandola, Italy) machines. Anticoagulation was provided with unfractionated heparin or citrate. Bilirubin and bile acids reduction ratios per session (RRs) were the main parameters for hepatic detoxification. Results Twelve patients with acute (n = 3) or acute-on-chronic (n = 9) liver failure were enrolled. Alcohol was the main cause of liver disease. Thirty-one CPFA treatments of 6 h each were performed, 19 with heparin and 12 with citrate. RRs was 28.8% (range 2.2–40.5) for total bilirubin, 32.7% (range 8.3–48.9) for direct bilirubin, 29.5% (range 6.5–65.4) for indirect bilirubin and 28.9% (16.7- 59.7) for bile acids. One patient received liver transplantation and 8/9 were alive at 1 year of follow-up. Three patients (25%) died: 2 during hospitalization and 1 for a cardiac event at 4 months of follow up with restored liver function. Conclusions CPFA resulted to be effective in liver detoxification. Thus, it may be considered as a “bridge technique” both to the liver transplant and to the recovery of the basal liver function.

Abstract
Hydrogen peroxide is an unavoidable by-product of cell metabolism, but when it is not properly managed by the body it can lead to several pathologies (e.g., premature aging, cardiovascular and neurodegenerative diseases, cancer). Several methods have been proposed for the measurement of intracellular H2O2 but none of them has proven to be selective. We developed a rapid all-in-one chemiluminescent bioassay for the quantification of H2O2 in living cells with a low limit of detection (0.15 μM). The method relies on an adamantylidene-1,2-dioxetane lipophilic probe containing an arylboronate moiety; upon reaction with H2O2 the arylboronate moiety is converted to the correspondent phenol and the molecule decomposes leading to an excited-state fragment that emits light. The probe has been successfully employed for quantifying intracellular H2O2 in living human endothelial, colon and keratinocyte cells exposed to different pro-oxidant stimuli (i.e., menadione, phorbol myristate acetate and lipopolysaccharide). Imaging experiments clearly localize the chemiluminescence emission inside the cells. Treatment of cells with antioxidant molecules leads to a dose-dependent decrease of intracellular H2O2 levels. As a proof of concept, the bioassay has been used to measure the antioxidant activity of extracts from Brassica juncea wastes, which contain glucosinolates, isothiocyanates and other antioxidant molecules.

Abstract
During space missions, real-time monitoring of astronauts' health status is of crucial importance and therefore there is a strong demand for simple analytical devices that astronauts can use to perform clinical chemistry analyses directly onboard. As part of the "IN SITU Bioanalysis" project, we designed a biosensor for analysing salivary levels of cortisol in astronauts, a marker of chronic stress. The biosensor is based on the Lateral Flow Immunoassay (LFIA) approach coupled with chemiluminescence (CL) detection and comprises a 3D-printed plastic cartridge containing a sealed fluidic element with the LFIA strip, in which the flow of sample and reagents is activated by pressing buttons on the cartridge and sustained by exploiting capillary forces. For measurement, the photon emission is imaged employing a CL reader based on an ultrasensitive cooled charge-coupled device (CCD) camera. The payload was designed to operate in microgravity and to withstand mechanical stress, such as take-off vibrations, and onboard depressurization events, while the microfluidics was developed considering alterations of physical phenomena occurring in microgravity, such as bubble formation, surface wettability and liquid evaporation. The biosensor, which was successfully used by the Italian astronaut Paolo Nespoli during the VITA mission (July-December 2017), demonstrated the feasibility of performing sensitive LFIA analysis of salivary cortisol down to 0.4 ng/mL directly onboard the International Space Station. It could be easily adapted for the analysis of other clinical biomarkers, thus enabling the early diagnosis of diseases and the timely activation of appropriate countermeasures.

Abstract
Long-duration space missions pose important health concerns for astronauts, especially regarding the adverse effects of microgravity and exposure to high-energy cosmic rays. The long-term maintenance of crew health and performance mainly relies on prevention, early diagnoses, condition management, and medical interventions in situ. In-flight biosensor diagnostic devices and medical procedures must use few resources and operate in a microgravity environment, which complicates the collection and management of biological samples. Moreover, the biosensors must be certified for in-flight operation according to strict design and safety regulations. Herein, we report on the state of the art and recent advances in biosensing diagnostic instrumentation for monitoring astronauts' health during long-duration space missions, including portable and wearable biosensors. We discuss perspectives on new-format biosensors in autonomous space clinics. We also describe our own work in developing biosensing devices for non-invasively diagnosing space-related diseases, and how they are used in long-duration missions. Finally, we discuss the benefits of space exploration for Earth-based medicine.

Abstract
Background: Dietary supplements of Carica papaya Linn fermented with yeast using a biotechnological process have well recognized positive effects on immunological, hematological, inflammatory, and oxidative stress parameters, utilized as biomarkers of chronic and degenerative diseases. Although many natural products fermented with lactic acid bacteria (LAB) have shown beneficial effects on the immune system and on antioxidant defenses, formulations of papaya fermented with LAB have not yet been studied.Aims: The aims of this study were to investigate the immunomodulatory activity linked to the type of papaya fermentation (yeast vs LAB) in macrophages and to evaluate whether the type of fermentation differently modulates oxidative stress both in cell free system and in a model of embryonic brain cells.Methods: Cytotoxicity was evaluated through cell proliferation kinetic and lactate dehydrogenase release assays; immunomodulatory activity through the transcriptional activation of inducible nitric oxide synthase (iNOS) and Tumor Necrosis Factor α (TNFα) by qRT-PCR in RAW 264.7 macrophages; antioxidant capacity was assessed, in cell free system and in pheochromocytoma cells embryonic brain cells, by measuring the intracellular ROS levels through a fluorescent dye.Results: Our data showed that all the formulations studied are safe at low concentrations (3-6 mg/ml); the LAB- fermented formulations promoted the expression of iNOS and TNFα more efficiently than yeast-fermented papaya preparation (p <0.001). In a cell free system, the LAB-fermented formulation acted as mild scavengers of ROS while, in cells, both formulations didn’t show any significant effect.Conclusions: This study corroborates previous reports showing the efficacy of yeast fermented papaya as a potent immunostimulant and highlights the beneficial contribution of lactic bacteria fermentation.Keywords: papaya, lactic fermentation, immunostimulant activity, antioxidant activity

Abstract
BACKGROUND AND AIMS Oxidized LDL (oxLDL) or pro-inflammatory stimuli lead to increased oxidative stress linked to endothelial dysfunction and atherosclerosis. The oxLDL receptor-1 (LOX1) is elevated within atheromas and cholesterol-lowering statins inhibit LOX1 expression. Berberine (BBR), an alkaloid extracted from plants of gender Berberis, has lipid-lowering and anti-inflammatory activity. However, its role in regulating LOX1-mediated signaling is still unknown. The aim of this study was to investigate the effect of BBR on oxLDL- and TNFα-induced endothelial dysfunction in human umbilical vein endothelial cells (HUVECs) and to compare it with that of lovastatin (LOVA). METHODS AND RESULTS Cytotoxicity was determined by lactate dehydrogenase assay. Antioxidant capacity was measured with chemiluminescent and fluorescent method and intracellular ROS levels through a fluorescent dye. Gene and protein expression levels were assayed by qRT-PCR and western blot, respectively. HUVECs exposure to oxLDL (30 μg/ml) or TNFα (10 ng/ml) for 24 h led to a significant increase in LOX1 expression, effect abrogated by BBR (5 μM) and LOVA (5 μM). BBR but not LOVA treatment abolished the TNFα-induced cytotoxicity and restored the activation of Akt signaling. In spite of a low direct antioxidant capacity, both compounds reduced intracellular ROS levels generated by treatment of TNFα but only BBR inhibited NOX2 expression, MAPK/Erk1/2 signaling and subsequent NF-κB target genes VCAM and ICAM expression, induced by TNFα. CONCLUSIONS These findings demonstrated for the first time that BBR could prevent the oxLDL and TNFα - induced LOX1 expression and oxidative stress, key events that lead to NOX, MAPK/Erk1/2 and NF-κB activation linked to endothelial dysfunction. CHEMICAL COMPOUNDS STUDIED IN THIS ARTICLE Berberine (PubChem CID: 2353); Lovastatin (PubChem CID: 53232).

Abstract
BACKGROUND & AIMS Indocyanine green retention test (ICG-r15) is a non-invasive marker of functional hepatic reserve. Among patients with compensated cirrhosis, ICG-r15 correlates to the degree of portal hypertension (PH); however, its prognostic relationship with the occurrence of decompensation events still requires clarification. METHODS ICG-r15 was prospectively measured in 154 patients with compensated cirrhosis. Patients with hepatocellular carcinoma (HCC), Child-Pugh B-C, MELD>15, bilirubin > 2 mg/dl, INR > 1.5 or portal vein thrombosis were excluded. All patients underwent laboratory tests, upper endoscopy and hepatic venous pressure gradient (HVPG). Decompensation, development of HCC, liver transplant and death were recorded and analysed through competing-risk analysis. RESULTS The study group was composed of 134 patients who were followed for a median of 39 months. During follow-up, 46 patients (34.3%) developed liver decompensation. Hepatocellular carcinoma occurred in 18 patients and two patients died from non-liver-related causes. The 1-, 2- and 3-year cumulative incidences of decompensation were 9.7%, 28.4% and 33.4% respectively. Patients with ICG-r15 < 10% did not experience any decompensation events during follow-up, while the 3-year cumulative incidence of decompensation of patients with ICG-r15 between 10% and 22.9% was 29.2% and that of patients with ICG-r15 ≥ 23% was 70.0% (P < 0.001). ICG-r15 gave the lowest pseudo-log-likelihood value, in comparison to oesophageal varices present, MELD, low platelet count and HVPG. CONCLUSIONS ICG-r15 appears to be strictly related to liver decompensation, longitudinally confirming the preliminary findings of its correlation with PH among patients with compensated cirrhosis, and can be used for patient prognostication.

Abstract
An integrated sensing system is presented for the first time, where a metal oxide semiconductor sensor-based electronic olfactory system (MOS array), employed for pathogen bacteria identification based on their volatile organic compound (VOC) characterisation, is assisted by a preliminary separative technique based on gravitational field-flow fractionation (GrFFF). In the integrated system, a preliminary step using GrFFF fractionation of a complex sample provided bacteria-enriched fractions readily available for subsequent MOS array analysis. The MOS array signals were then analysed employing a chemometric approach using principal components analysis (PCA) for a first-data exploration, followed by linear discriminant analysis (LDA) as a classification tool, using the PCA scores as input variables. The ability of the GrFFF-MOS system to distinguish between viable and non-viable cells of the same strain was demonstrated for the first time, yielding 100 % ability of correct prediction. The integrated system was also applied as a proof of concept for multianalyte purposes, for the detection of two bacterial strains (Escherichia coli O157:H7 and Yersinia enterocolitica) simultaneously present in artificially contaminated milk samples, obtaining a 100 % ability of correct prediction. Acquired results show that GrFFF band slicing before MOS array analysis can significantly increase reliability and reproducibility of pathogen bacteria identification based on their VOC production, simplifying the analytical procedure and largely eliminating sample matrix effects. The developed GrFFF-MOS integrated system can be considered a simple straightforward approach for pathogen bacteria identification directly from their food matrix. Graphical abstract An integrated sensing system is presented for pathogen bacteria identification in food, in which field-flow fractionation is exploited to prepare enriched cell fractions prior to their analysis by electronic olfactory system analysis.

Abstract
We have developed a simple and accurate biosensor based on a chemiluminescent (CL)-lateral flow immunoassay (LFIA) method integrated in a smartphone to quantitatively detect salivary cortisol. The biosensor is based on a direct competitive immunoassay using peroxidase-cortisol conjugate, detected by adding the chemiluminescent substrate luminol/enhancer/hydrogen peroxide. The smartphone camera is used as light detector, for image acquisition and data handling via a specific application. We 3D-printed simple accessories to adapt the smartphone. The system comprises a cartridge, which houses the LFIA strip, and a smartphone adaptor with a plano-convex lens and a cartridge-insertion slot. This provides a mini-darkbox and aligned optical interface between the camera and the LFIA membrane for acquiring CL signals. The method is simple and fast, with a detection limit of 0.3 ng/mL. It provides quantitative analysis in the range of 0.3-60 ng/mL, which is adequate for detecting salivary cortisol in the clinically accepted range. It could thus find application in the growing area of home-self-diagnostic device technology for clinical biomarker monitoring, overcoming the current difficulties in achieving sensitive and quantitative information with conventional systems taking the advantage of smartphone connectivity and the enhanced performance of the included camera.

Abstract
In this paper, we report, for the first time, the use of a smartphone to image and quantify biochemiluminescence coupled biospecific enzymatic reactions to detect analytes in biological fluids. Using low-cost three-dimensional (3D) printing technology, we fabricated a smartphone accessory and a minicartridge for hosting biospecific reactions. As a proof-of-principle, we report two assays: a bioluminescence assay for total bile acids using 3α-hydroxyl steroid dehydrogenase coimmobilized with bacterial luciferase system and a chemiluminescence assay for total cholesterol using cholesterol esterase/cholesterol oxidase coupled with the luminol-H2O2-horseradish peroxidase system. These assays can be performed within 3 min in a very straightforward manner and provided adequate analytical performance for the analysis of total cholesterol in serum (limit of detection (LOD) = 20 mg/dL) and total bile acid in serum and oral fluid (LOD = 0.5 μmol/L) with a reasonable accuracy and precision. Smartphone-based biochemiluminescence detection could be thus applied to a variety of clinical chemistry assays.

Abstract
UNLABELLED Noninvasive markers would be useful for the assessment of portal hypertension (PH) and esophageal varices (EV) in patients with cirrhosis. The aim of our study was to evaluate the performance of the indocyanine green (ICG) retention test as a noninvasive marker of PH and EV, measured against the gold standards (hepatic venous pressure gradient [HVPG] measurement and upper endoscopy). We prospectively enrolled patients with compensated cirrhosis referral to our unit. All patients underwent laboratory tests, abdominal ultrasound, upper gastrointestinal endoscopy, HVPG measurement, and the ICG 15-minute retention (ICG-r15) test. We evaluated the sensitivity and specificity of the ICG retention test and other noninvasive tools for the diagnosis of PH and EV. Ninety-six consecutive Child-Pugh A patients (67 male and 29 female; 60.3 ± 11.8 years of age) were enrolled. Seventy-four patients had clinically significant portal hypertension (CSPH), of whom 59 had severe portal hypertension (SPH). ICG-r15 and Lok index were independently related to the presence of both CSPH and SPH, whereas ICG-r15 and INR were related to EV. ICG-r15 values (<6.7% and <6.9%, respectively) were able to rule out the presence of CSPH and SPH (LR(-) 0.15 and 0.14); ICG-r15 <10% provided a 97.8% sensitivity (LR(-) 0.042) for the exclusion of EV and a 100% sensitivity (LR(-) 0.0) for large EV. CONCLUSION The ICG-r15 test is an effective tool for assessment of PH in patients with compensated cirrhosis. Although this would not replace endoscopy, the ICG-r15 appears able to identify patients with advanced liver disease in which endoscopy is mandatory as well as rule out the presence of EV in patients with compensated cirrhosis.

Abstract
AIM: To develop an integrated approach for monitoring gastrointestinal motility and inflammation state suitable for application in long-term spaceflights.
METHODS: Breath tests based on the oral administration of 13C-labeled or hydrogen-producing substrates followed by the detection of their metabolites (13CO2 or H2) in breath were used to measure gastrointestinal motility parameters during the 520-d spaceflight ground simulation within the MARS-500 Project. In particular, the gastric emptying rates of solid and liquid contents were evaluated by 13C-octanoic acid and 13C-acetate breath tests, respectively, whereas the orocecal transit time was assessed by an inulin H2-breath test, which was performed simultaneously with the 13C-octanoic acid breath test. A ready-to-eat, standardized pre-packaged muffin containing 100 mg of 13C-octanoic acid was used in the 13C-octanoic acid breath test to avoid the extemporaneous preparation of solid meals. In addition, a cassette-type lateral flow immunoassay was employed to detect fecal calprotectin, a biomarker of intestinal inflammation. Because no items could be introduced into the simulator during the experiment, all materials and instrumentation required for test performance during the entire mission simulation had to be provided at the beginning of the experiment.
RESULTS: The experiments planned during the simulation of a manned flight to Mars could be successfully performed by the crewmembers without any external assistance. No evident alterations (i.e., increasing or decreasing trends) in the gastric emptying rates were detected using the 13C-breath tests during the mission simulation, as the gastric emptying half-times were in the range of those reported for healthy subjects. In contrast to the 13C-breath tests, the results of the inulin H2-breath test were difficult to interpret because of the high variability of the H2 concentration in the breath samples, even within the same subject. This variability suggested that the H2-breath test was strongly affected by external factors, which may have been related to the diet of the crewmembers or to environmental conditions (e.g., the accumulation of hydrogen in the simulator microenvironment). At least in closed microenvironments such as the MARS-500 simulator, 13C-breath tests should therefore be preferred to H2-breath tests. Finally, the fecal calprotectin test showed significant alterations during the mission simulation: all of the crewmembers were negative for the test at the beginning of the simulation but showed various degrees of positivity in at least one of the subsequent tests, thus indicating the onset of an intestinal inflammation.
CONCLUSION: Breath tests, especially those 13C-based, proved suitable for monitoring gastrointestinal motility in the 520-d isolation experiment within MARS-500 project and can be applied in long-term spaceflights.

Abstract
Cerebrotendinous xanthomatosis (CTX) is a rare and treatable autosomal recessive disease. The diagnosis should be suspected in the presence of a suggestive clinical triad characterized by early-onset cataract, tendinous xanthomata and neurological symptoms and signs, notably cerebellar ataxia, mental retardation and pyramidal syndrome.The diagnosis is confirmed by demonstrating an increased blood level of cholestanol, or/and by molecular genetic analysis.In typical cases, brain MRI shows bilateral hyperintensity of the cerebellar nucleus dentatus together with cerebral atrophy and leukoencephalopathy. The treatment is based on the administration of chenodeoxycholic acid. The aim is to restore the negative feedback on the enzymatic cascade altered by mutation in the gene CYP27 which induces a 27-hydroxylase deficiency

Abstract
The aim of this article is to present the value and limitations of image-guided percutaneous biopsy in spinal disorders. The indications and contraindications of percutaneous spinal biopsy and the different techniques and materials used are discussed. The decision for this type of biopsy and the choice of technique should be made by a multidisciplinary team. Percutaneous spinal biopsy is a safe, inexpensive and possible as an outpatient. The effectiveness of percutaneous spinal biopsy is around 70%.

Abstract
AIM: To investigate the effect of drinking sulphate-bicarbonate-calcium thermal water (TW) on risk factors for atherosclerosis and cholesterol gallstone disease.
METHODS: Postmenopausal women with functional dyspepsia and/or constipation underwent a 12 d cycle of thermal (n = 20) or tap (n = 20) water controlled drinking. Gallbladder fasting volume at ultrasound, blood vitamin E, oxysterols (7-β-hydroxycholesterol and 7-ketocholesterol), bile acid (BA), triglycerides, total/low density lipoprotein and high density lipoprotein cholesterol were measured at baseline and at the end of the study. Food consumption, stool frequency and body weight were recorded daily.
RESULTS: Blood lipids, oxysterols and vitamin E were not affected by either thermal or tap water consumption. Fasting gallbladder volume was significantly (P < 0.005) smaller at the end of the study than at baseline in the TW (15.7 ± 1.1 mL vs 20.1 ± 1.7 mL) but not in the tap water group (19.0 ± 1.4 mL vs 19.4 ± 1.5 mL). Total serum BA concentration was significantly (P < 0.05) higher at the end of the study than at baseline in the TW (5.83 ± 1.24 μmol vs 4.25 ± 1.00 μmol) but not in the tap water group (3.41 ± 0.46 μmol vs 2.91 ± 0.56 μmol). The increased BA concentration after TW consumption was mainly accounted for by glycochenodeoxycholic acid. The number of pasta (P < 0.001), meat (P < 0.001) and vegetable (P < 0.005) portions consumed during the study and of bowel movements per day (P < 0.05) were significantly higher in the TW than in the tap water group. Body weight did not change at the end of the study as compared to baseline in both groups.
CONCLUSION: Sulphate-bicarbonate-calcium water consumption has a positive effect on lithogenic risk and intestinal transit and allows maintenance of a stable body weight despite a high food intake.

Abstract
Due to the importance of intestinal transport in pharmacological studies and the emerging role of intestinal signaling activity in the gut-liver axis, we have developed a new method to investigate intestinal transport and liver signaling using cell and serum free mesenteric perfusion system in the rat. The method regarding bile acid active absorption was validated, then, the portal venous content was examined for fibroblast growth factor 15(FGF15), a putative signaling protein produced by the ileal enterocytes following bile acid absorption. After isolation and cannulation of the relevant vessels (abdominal aorta and portal vein), the abdominal aorta and the terminal ileum were infused with respectively Krebs-Ringer solution and tauroursodeoxycholate (TUDCA) and the absorption was assessed by its recovery in the portal vein. After immunoblot, liquid chromatography and mass spectrometry analysis were performed both on gel bands digestion products and on portal outflow samples in order to evaluate if negligible amounts of FGF15 were present in the portal circulation. TUDCA absorption was efficient, intestinal morphology and oxygen consumption were normal. Despite accurate analysis, we could not find FGF15. Our method proved to be reliable for studying the active bile acid absorption. It is also suitable to identify molecules produced by enterocytes and transferred to the portal circulation in response to absorption of different substances such as nutrients or drugs. Since FGF15 was not recovered we suggest the possibilities that this protein is produced in very little amounts, poorly transferred outside the cell, or that it is extremely unstable and rapidly degraded.

Abstract
Transient bone marrow edema of the hip is characterized by moderate homogeneous low MR signal intensity with ill-defined margins that involves at least a portion of the femoral head. Spin echo T1-weighted images are helpful to exclude other underlying diseases (tumor, infection, necrosis from systemic origin…), for which marrow edema is secondary or no epiphyseal in location. High-resolution fat-suppressed T2-weighted or proton density images allow evaluation of the articular cartilage, subchondral bone and subchondal marrow: if the articular cartilage is abnormal, the lesion is irreversible (arthrosis or necrosis); if the subchondral bone is focally interrupted and/or if the femoral is no longer spherical, the lesion is irreversible (necrosis); if a focal linear fluid collection is present under the subchondral bone, the lesion is irreversible (necrosis). Finally, subchondral changes may provide useful prognostic information: the absence of any abnormality other than marrow edema typically indicates that complete resolution is likely; the presence of a focal T2-weighted hypointense lesion immediately next to the subchondral bone suggests an irreversible lesion, especially if it is equal to or thicker than 4mm or the joint space. In some instances, prognosis cannot be reliably determined requiring the need for follow-up imaging.

Abstract
BACKGROUND Exocrine pancreatic dysfunction has been reported in humans in the convalescent period after acute pancreatitis, but the data are scarce and conflicting. This study aimed to prospectively assess the exocrine pancreatic function in patients with acute pancreatitis at the time of their refeeding. METHODS Fecal elastase-1 was determined on the day of refeeding in all consecutive acute pancreatitis patients with their first episode of the disease. They were 75 patients including 60 (80.0%) patients with mild acute pancreatitis and 15 (20.0%) patients with severe acute pancreatitis. Etiologically 61 patients (81.3%) had biliary disease, 1 (1.3%) had alcoholic disease and 3 (4.0%) had hypertriglyceridemia. No causes of acute pancreatitis were found in the remaining 10 patients (13.3%). The mean (+/-SD) refeeding time after the attack of acute pancreatitis was 11.2+/-10.2 days. RESULTS Pathological values of fecal elastase-1 were found in 9 of the 75 patients (12.0%): 7 (9.3%) patients with mild pancreatitis and 2 (2.7%) patients with severe pancreatitis (P=1.000). The frequency of the pathological values of fecal elastase-1 was significantly different from that of various etiologies of the disease (P=0.030). It was significantly lower in patients with biliary pancreatitis (9.8%; P=0.035) than in one patient with alcoholic pancreatitis (P=0.126), one patient with hypertriglyceridemia-induced pancreatitis (33.3%; P=0.708), and one patient with idiopathic pancreatitis (10.0%; P=0.227). Pathological fecal elastase-1 was not significantly related to sex, age or day of refeeding. CONCLUSION Exocrine pancreatic function should be routinely assessed in patients with acute pancreatitis at the time of refeeding in order to supplement their diet with pancreatic extracts.

Abstract
BACKGROUND Among the various studies of pancreatic function in the elderly published so far, none have dealt with subjects over 90 years of age. The aim of this study was to examine pancreatic function in healthy individuals over 90 years old. METHODS Sixty-eight healthy noninstitutionalized elderly persons, aged 91-104 years, with a mean age of 95 years, and 63 younger controls were studied. Pancreatic function was studied by determining fecal elastase 1 concentration. In addition to this test, we also measured serum amylase, pancreatic isoamylase and lipase in 53 of the 68 elderly subjects. RESULTS All but 1 of the 68 elderly subjects had normal elastase 1 values; the one who did not had a value slightly below normal. No significant difference with controls was found. Serum pancreatic enzymes were normal in almost all of the 53 elderly studied; 3 had a mild elevation only of amylase and 1 had a persistent elevation of amylase, pancreatic isoamylase and lipase. CONCLUSIONS In subjects over 90 years of age, exocrine pancreatic function continues to be normal; if an impairment occurs, it is mild and not significant for digestion of food. In addition, serum pancreatic enzymes remain within normal limits in the vast majority of cases.

Abstract
Classification of cervical intraepithelial neoplasia (CIN) lesions in low-grade (CIN1) or high-grade (CIN2-3) ones is crucial for optimal patient management, but current histological diagnosis on bioptic samples is often hampered by inter-observer variability. To allow objective classification, we have exploited the peculiar characteristics of chemiluminescence detection, such as high sensitivity and easy quantification of the luminescence signal, to perform sequentially in the same tissue section both an immunohistochemical quantitative detection of p16(INK4A) (a protein marker of high-grade CIN lesions) and an in situ hybridization for human papillomavirus (generally accepted as a necessary but insufficient cause of cervical carcinoma). Different label enzymes (alkaline phosphatase and horseradish peroxidase) were employed in order to avoid any interference between the two assays, and quantitative chemiluminescence image analysis was used to obtain objective evaluation of sample positivity. The multiplexed method allowed detection of two complementary biomarkers and provided discrimination between different lesions (non-neoplastic, low-grade and high-grade CIN). This assay might thus represent an accurate and objective diagnostic test providing important information for counseling, selection of therapy and follow up after surgical treatment.

Abstract
OBJECTIVES Little is known about the natural history and pathogenesis of small gallbladder polyps (<10 mm, usually of the cholesterol type), particularly in Western populations. It is unclear if these polyps and gallstones represent different aspects of the same disease. The aim of this study was to characterize the natural history and pathogenesis of small gallbladder polyps. METHODS Fifty-six Caucasian patients with small gallbladder polyps, 30 matched gallstone patients, and 30 controls were enrolled in this 5-year prospective study. Patients underwent a symptomatic questionnaire, abdominal ultrasonography, and ultrasonographic evaluation of gallbladder motility at baseline and yearly intervals for 5 years. Cholesterol saturation index, cholesterol crystals in bile, and apolipoprotein E genotype were also determined. RESULTS Most patients with polyps (mean size: 5.3 mm) were men (61%), asymptomatic, and had multiple polyps (57%). Polyps did not change in 91% of patients during follow-up. No subject experienced biliary pain or underwent cholecystectomy; four developed gallstones. Cholesterol saturation index was higher in patients with polyps or gallstones than in controls (P<0.05). Cholesterol crystals were more frequent in patients with polyps than in controls (P<0.0001) but less common than in gallstone patients (P<0.0001). Polyps and gallstones were associated with nonapolipoprotein E4 phenotypes. CONCLUSIONS The natural history of small gallbladder polyps was benign, as no patient developed specific symptoms and/or morphological changes in polyps. Consequently, a "wait and see" policy is advisable in these patients. Polyps have some pathogenetic mechanisms in common with gallstones, but few patients developed gallstones.

Abstract
Ursodeoxycholic acid (UDCA), previously used for cholesterol gallstone dissolution, is currently considered the first choice therapy for many forms of cholestatic syndromes. Many mechanisms and sites of action have been proposed for UDCA, but definitive data are still missing regarding the key points of its efficacy and optimal dosage in order to achieve a sustained clinical effect. Among the suggested mechanisms of action of UDCA, changes in bile acid pool composition, hepatocyte membrane protection, immunomodulatory effects and bicarbonate-rich hypercholeresis have been extensively studied. However, recent evidence indicate that UDCA is a potent intracellular signalling agent that counterbalances impaired biliary secretion, inhibits hepatocyte apoptosis and protects injured cholangiocytes against toxic effects of bile acids. It is clear that the relative contribution of these mechanisms to the anticholestatic action of UDCA depends on the type and stage of the liver injury. Available clinical evidence suggest that UDCA treatment has to be initiated as early as possible and that higher doses could be more efficacious in inducing and maintaining clinical remission of cholestatic diseases. The future availability of UDCA derivatives will possibly enhance the chances to effectively treat chronic cholestatic diseases.

AIM To evaluate whether ursodeoxycholic acid affects MRP2, MRP3 and MRP4 expression in the placenta. MATERIALS AND METHODS Forty-three pregnant women were enrolled; fourteen subjects had physiological pregnancies. Intrahepatic cholestasis of pregnancy patients were divided into two groups: (i) 13 received ursodeoxycholic acid (20 mg/kg/day) and (ii) 16 untreated. Total bile acid and bilirubin in serum and cord blood were determined in each subject. Multidrug resistance proteins expression (immunoblot, quantitative real-time PCR) was evaluated in placentas collected at delivery. anova test was used for statistical analysis of data. RESULTS Ursodeoxycholic acid administration significantly improved maternal serum bile acid and cord blood bilirubin and bile acid levels. MRP2 protein and RNA expression was significantly increased in placentas from treated patients compared to controls (P < 0.001 and P < 0.01, respectively). MRP3 protein expression was not significantly different between the groups while RNA expression was significantly decreased in treated patients (P < 0.01). MRP4 did not show significant differences between the groups. CONCLUSIONS Ursodeoxycholic acid administration induces placental MRP2 expression, and reduces bilirubin and bile acid levels in cord blood.
