Background: People with substance or alcohol use disorders (SUDs/AUDs) are likely to be more vulnerable to COVID-19 infection than the general population, but the evidence of COVID-19-related mortality in these patients is unclear. Objectives: The aim of the study was to verify whether patients with AUD and SUD have a higher mortality rate for COVID-19-related mortality compared to the general population. Method: We performed a follow-up study to assess mortality in 2020 in a cohort of patients diagnosed for the first time with AUDs or SUDs at the Public Health Services in the metropolitan area of Bologna (Northern Italy) from 2009 to 2019. Results: SUDs/AUDs patients present an excess mortality with respect to the general population for all causes of death and for COVID-19-related mortality. Conclusions: Our data support the need for prevention strategies in SUDs/AUDs patients such as vaccinations.

Il gioco d'azzardo ha una diffusione pervasiva nella società contemporanea e può esitare nel disturbo da gioco d'azzardo - DGA - che determina gravi disagi personali, familiari e sociali. Il progetto di ricerca e intervento è stato svolto presso 8 sale bingo di 6 città della regione Emilia Romagna (Modena, Lugo, Bologna, Parma, Cesena, Cesenatico), con i seguenti obiettivi: a) valutare l'incidenza di indicatori di gioco problematico, di stigma per il gioco, di assunzione problematica di acolici, di distress psicofisico negli utenti delle sale bingo; b) valutare se le sale bingo e i loro operatori possano promuovere comportamenti di gioco responsabile; c) verificare la fattibilità e il gradimento di interventi di socio-psico-educazione per la promozione del benessere psicofisico nelle sale bingo. Il progetto è stato svolto in 3 fasi: I) screening dei giocatori; II) focus group per gli operatori; III) intervento di socio-psico-educazione. Dei 98 giocatori intervistati, il 40 % riferisce di avere un comportamento problematico e il 33% stigma per il gioco. Gli operatori hanno mostrato consapevolezza dei problemi psico-sociali legati al gioco d'azzardo e disponibilità a promuovere comportamenti sani. Gli interventi socio-psicoeducativi hanno attratto i giocatori, che hanno richiesto informazioni e talora supporto. I risultati del progetto incoraggiano l'implementazione di azioni che consentano la trasformazione sociale delle sale bingo da loghi dove occultare abitudini negative a luoghi dove promuovere comportamenti sani sia possibile.

We assessed long-term mortality and its association with chronic alcohol-related diseases in patients admitted to the emergency department (ED) because of acute alcoholic intoxication (AAI). A retrospective cohort study was performed at the ED of Sant’Orsola-Malpighi Hospital, Bologna, Italy. 3304 patients, corresponding to 6415 admissions for AAI, who accessed the ED from January 1, 2005, to December 31, 2017, were studied. The ED electronic registry system was used to assess living status on 08 May 2020 and to obtain the prespecified potential predictors, i.e., age at first admission, sex, alcohol use disorder (AUD), substance use disorder (SUD), more than 1 admission to ED for trauma, mental and behavioral disorders, neurological disorders, and cardiovascular disease. The median follow-up time was 9.3 years and the time on risk was 30,053 person years (PY) with a death rate corresponding to 4.42 (95% CI 3.74–5.26) per 1000 PY (n = 133 deaths). The death rate was higher in patients with AUD (17.30) than in those without AUD (1.98) and in those with SUD (13.58) than in those without SUD (3.80). Lastly, there was a clearly higher death rate among AUD+ SUD+ (20.89) compared to AUD–SUD–patients (1.74). At multivariable Cox regression, AUD, SUD, and liver cirrhosis were strong and independent predictors of time-to-death. Using standardized mortality ratios, a clear excess of mortality was evident for all the age bands from (40–45] to (60–65] years. Mortality is higher in AAI than in the general population and chronic alcohol-related diseases are strongly associated with it.

Background and Aims: Circulating albumin in cirrhosis can be dysfunctional because of accumulating structural damages, leading to the concept of effective albumin concentration (eAlb), referring to the albumin portion presenting structural and functional integrity. We aimed to estimate eAlb in patients with decompensated cirrhosis and analyze its relationships with albumin function and clinical outcomes as compared to total albumin concentration (tAlb). Approach and Results: We evaluated 319 patients with cirrhosis hospitalized for acute decompensation (AD) with and without acute-on-chronic liver failure (ACLF) and 18 age- and sex-comparable outpatients with compensated cirrhosis. tAlb was quantified by standard assay, whereas eAlb was estimated combining liquid chromatography/electrospray ionization/mass spectrometry and standard methods. Albumin binding and detoxification efficiency were evaluated by electron paramagnetic resonance analysis. Circulating albumin in patients with decompensated cirrhosis displayed multiple structural abnormalities, with reversible oxidation and glycation being the most frequent. As a result, eAlb progressively declined with the worsening of cirrhosis and was superior to tAlb in stratifying patients between compensated cirrhosis, AD, and ACLF, as well as patients with and without complications. Moreover, eAlb, but not tAlb, was closely associated with binding capacities in ACLF. Finally, eAlb at admission predicted the occurrence of ACLF within 30 days and mortality at 90 days better than tAlb. Conclusions: This large, observational study provides the evidence in patients with decompensated cirrhosis that eAlb can be quantified and differentiated from tAlb routinely measured in clinical practice. As compared to tAlb, eAlb is more closely associated with disease severity and albumin dysfunction and carries a greater prognostic power. These results prompt future research assessing eAlb as a biomarker for predicting prognosis and treatment response.

We assessed the impact of long-term albumin administration to hyponatremic patients with ascites enrolled in the ANSWER trial.The normalization rate of baseline hyponatremia and the 18-month incidence rate of at least moderate hyponatremia were evaluated.The hyponatremia normalization rate was higher with albumin than with standard medical treatment (45% vs 28%, P = 0.042 at 1 month). Long-term albumin ensured a lower incidence of at least moderate hyponatremia than standard medical treatment (incidence rate ratio: 0.245 [CI 0.167-0.359], P0.001).Long-term albumin administration improves hyponatremia and reduces episodes of at least moderate hyponatremia in outpatients with cirrhosis and ascites.

Background: Comprehensive and contemporary data pertaining large populations of patients with Primary Biliary Cholangitis (PBC) and hepatocellular carcinoma (HCC) are missing. Aim: To describe main characteristics and outcome of PBC patients with HCC diagnosed in the new millennium. Methods: Analysing the Italian Liver Cancer registry we identified 80 PBC patients with HCC diagnosed after the year 2000, and described their clinical characteristics, access to treatment and survival. Results: Median age of patients was 71 years and 50.0% were males. Cirrhosis was present in 86.3% of patients, being well-compensated in 58.0%. Median HCC diameter was smaller in patients under surveillance (2.6vs 4.0cm, P=0.007). Curative treatment, feasible in 50.0% of patients, was associated with improved survival compared to palliative and supportive care (42vs 33vs 6 months, P

Background and aimsCurrent prognostic scores of patients with acutely decompensated cirrhosis (AD), particularly those with acute-on-chronic liver failure (ACLF), underestimate the risk of mortality. This is probably because systemic inflammation (SI), the major driver of AD/ACLF, is not reflected in the scores. SI induces metabolic changes, which impair delivery of the necessary energy for the immune reaction. This investigation aimed to identify metabolites associated with short-term (28-day) death and to design metabolomic prognostic models.MethodsTwo prospective multicentre large cohorts from Europe for investigating ACLF and development of ACLF, CANONIC (discovery, n=831) and PREDICT (validation, n=851), were explored by untargeted serum metabolomics to identify and validate metabolites which could allow improved prognostic modelling.ResultsThree prognostic metabolites strongly associated with death were selected to build the models. 4-Hydroxy-3-methoxyphenylglycol sulfate is a norepinephrine derivative, which may be derived from the brainstem response to SI. Additionally, galacturonic acid and hexanoylcarnitine are associated with mitochondrial dysfunction. Model 1 included only these three prognostic metabolites and age. Model 2 was built around 4-hydroxy-3-methoxyphenylglycol sulfate, hexanoylcarnitine, bilirubin, international normalised ratio (INR) and age. In the discovery cohort, both models were more accurate in predicting death within 7, 14 and 28 days after admission compared with MELDNa score (C-index: 0.9267, 0.9002 and 0.8424, and 0.9369, 0.9206 and 0.8529, with model 1 and model 2, respectively). Similar results were found in the validation cohort (C-index: 0.940, 0.834 and 0.791, and 0.947, 0.857 and 0.810, with model 1 and model 2, respectively). Also, in ACLF, model 1 and model 2 outperformed MELDNa 7, 14 and 28 days after admission for prediction of mortality.ConclusionsModels including metabolites (CLIF-C MET) reflecting SI, mitochondrial dysfunction and sympathetic system activation are better predictors of short-term mortality than scores based only on organ dysfunction (eg, MELDNa), especially in patients with ACLF.

Sarcopenia is a prevalent condition in patients with Crohn’s disease (CD), representing an independent predictor factor for the development of major postoperative complications. Thus, a proper assessment of the muscle strength, by using different validated tools, should be deemed an important step of the clinical management of these patients. Patients with CD are frequently malnourished, presenting a high prevalence of different macro- and micro-nutrient deficiencies, including that of vitamin D. The available published studies indicate that vitamin D is involved in the regulation of proliferation, differentiation, and regeneration of muscle cells. The relationship between vitamin D deficiency and sarcopenia has been extensively studied in other populations, with interesting evidence in regards to a potential role of vitamin D supplementation as a means to prevent and treat sarcopenia. The aim of this review was to find studies that linked together these pathological conditions.

OBJECTIVE: We externally validated the fatty liver index (FLI), the lipid accumulation product (LAP), the hepatic steatosis index (HSI), and the Zhejiang University index (ZJU) for the diagnosis of fatty liver (FL) and non-alcoholic fatty liver disease (NAFLD) in the general population. SUBJECTS AND METHODS: The validation was performed on 2159 citizens of the town of Bagnacavallo (Ravenna, Italy). Calibration was evaluated by calculating the calibration slope and intercept and by inspecting calibration plots; discrimination was evaluated using the c-statistic. RESULTS: The average calibration slope was 1 and the average intercept was 0 for all combinations of outcomes and biomarkers. As for FL, the c-statistic was 0.85 for FLI, 0.83 for ZJU, 0.82 for HSI, and 0.80 for LAP. As for NAFLD, the c-statistic was 0.77 for FLI, 0.76 for ZJU, 0.75 for HSI, and 0.74 for LAP. All the biomarkers were strongly correlated with each other. CONCLUSION: FLI, LAP, HSI, and ZJU can be used to diagnose FL in the Bagnacavallo population, even if FLI has the highest discriminative ability. The same biomarkers perform similarly for the diagnosis of NAFLD even if FLI has a small advantage as discrimination is concerned.

Background Bacterial and fungal infections (BFIs) are frequent in patients with cirrhosis and often trigger acute-on-chronic liver failure (ACLF). This prospective observational study aims to describe the interactions between BFI and ACLF in terms of mortality and related risk factors. Methods We performed a 2-center prospective observational study enrolling hospitalized patients with cirrhosis admitted for acute decompensation. Data were recorded at admission and during hospitalization. Survival was recorded up to 1 year. Results Among the 516 patients enrolled, 108 (21%) were infected at admission, while an additional 61 patients (12%) developed an infection during hospital stay. In the absence of ACLF, the 1-year mortality rate of patients with BFI did not differ from that of patients without BFI (33% vs 31%; P = .553). In contrast, those with ACLF triggered or complicated by BFI had a significantly higher mortality rate than those who remained free from BFI (75% vs 54%; P = .011). Competing risk analysis showed that the negative impact of ACLF-related BFI on long-term prognosis was independent from Model for End-stage Liver Disease (MELD) incorporating serum sodium concentration score, comorbidity, and basal C-reactive protein level. Finally, multivariable logistic regression showed that higher MELD score (P, The adverse prognosis of bacterial or fungal infections in patients with decompensated cirrhosis is linked to the development of acute-on-chronic liver failure. Severity, type and microbiological features of infections are main predictors of the development of acute-on-chronic liver failure.

Cohort study. This follow-up study (from 1975 to 2016) was aimed to estimate the mortality risk for suicide in a cohort of patients presenting to a public treatment centre for addiction (SERD) with Alcohol Use Disorder (AUD), Heroin Use Disorder - HUD or Cocaine Use Disorder (CUD), also relating to their access to a Mental Heath Service. Crude Mortality Rates for suicide were higher for patients with AUDs, for men and subjects 45–64 years old. Hanging was the main cause of suicide death. We highlight an increase in mortality in the period 2009–2012, which coincides with the economic recession, and in the year of first contact with a SERD. The Standardized Mortality Ratios (SMRs) were 4.9, higher among females than males. From the multivariate analysis, a higher risk for patients that were separated or divorced was observed. The results of our study provide some guidance on the features of subjects at greatest risk of death from suicide, which may be useful in reducing and preventing suicide and gaining a better clinical management of patients with SUDs.

Background: Despite the robust data available on inflammatory indices (neutrophil lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR), and systemic immune-inflammation index (SII)) and clinical outcome in oncological patients, their utility as a predictor of cancer incidence in the general population has not been reported in literature. Methods: The Bagnacavallo study was performed between October 2005 and March 2009. All citizens of Bagnacavallo (Ravenna, Emilia-Romagna, Italy) aged 30–60 years as of January 2005 were eligible and were invited by written letter to participate to the study. All participants underwent a detailed clinical history and physical examination following the model of the Dionysos Study. All blood values included in the analysis were obtained the day of physical examination. Cancer incidence data were obtained from the population-based Romagna Cancer Registry, which operates according to standard methods. The aim of this analysis was to examine the association between metabolic syndrome and baseline SII, NLR, and PLR levels, and the diagnosis of an invasive cancer in the Bagnacavallo study cohort. Results: At univariate analysis, metabolic syndrome was not associated with an increase of cancer incidence (HR 1.30, p = 0.155). High glucose (HR 1.49, p = 0.0.16), NLR HR 1.54, p = 0.002), PLR (HR 1.58, p = 0.001), and SII (HR 1.47, p = 0.006) were associated with an increase of cancer incidence. After adjusting for clinical covariates (smoking, physical activity, education, age, and gender) SII, PLR, and NLR remained independent prognostic factors for the prediction of cancer incidence. Conclusions: Inflammatory indices are promising, easy to perform, and inexpensive tools for identifying patients with higher risk of cancer in cancer-free population.

Background & Aims: The ANSWER study reported that long-term albumin administration in patients with cirrhosis and uncomplicated ascites improves survival. During treatment, serum albumin increased within a month and remained stable thereafter. In this post hoc analysis, we aimed to determine whether on-treatment serum albumin levels could guide therapy. Methods: Logistic regression was used to assess the association between baseline serum albumin and mortality, as well as to determine on-treatment factors associated with mortality and to predict the achievement of a given on-treatment serum albumin level. Survival was assessed by Kaplan-Meier estimates and second-order polynomial regression. Patients whose on-treatment serum albumin remained below normal were compared with a subset of patients from the control arm matched by principal score. Results: Baseline serum albumin was closely associated with 18-month mortality in untreated patients; albumin treatment almost effaced this relationship. On-treatment serum albumin and MELD-Na at month 1 were the sole independent variables associated with mortality. Second-order polynomial regression revealed that survival improved in parallel with increased 1-month on-treatment serum albumin. Kaplan-Meier estimations showed that any value of 1-month on-treatment serum albumin (0.1 g/dl intervals) in the range 2.5–4.5 g/dl discriminated patient survival. In the normal range of serum albumin, the best discriminant value was 4.0 g/dl. Compared to untreated patients, survival even improved in patients whose on-treatment serum albumin remained below normal. Conclusion: Baseline serum albumin per se should not guide the decision to start albumin therapy. Conversely, 1-month on-treatment serum albumin levels are strongly associated with outcomes and could guide the use of albumin – 4.0 g/dl being the target threshold. However, even patients whose serum albumin remains below normal benefit from long-term albumin administration. Lay summary: The ANSWER study has shown that long-term albumin administration improves survival and prevents the occurrence of major complications in patients with cirrhosis and ascites. This study shows that the achievement of these beneficial effects is related to a significant increase in serum albumin concentration. Even though the best results follow the achievement of a serum albumin concentration of 4 g/dl, a survival benefit is also achieved in patients who fail to normalise serum albumin.

Daily Evaluation of COVID-19 Patients Primarily Based on Lung Ultrasound: In Times of Emergency, It's Time to Change Some Paradigms.

Background: In Italy, although the number of foreign-born residents has grown exponentially, there are still few studies oriented to the alcohol misuse concerning the population of minors. Our objective was to describe characteristics of minors (natives and non-natives) admitted to the Emergency Departments (ED) following Alcohol Acute Intoxication (AAI) in Northern Italy. Methods: We retrospectively evaluated all the records of patients aged 12–17 years admitted from 2009 to 2017 to 11 EDs. Results: Out of 97,445 minors, we identified 554 AAI: 39.2% female, 22.7% non-natives, 21% reported illegal substance use. We highlight a quote of 5.7 AAI admissions every thousand ED admissions, rising over time, higher among males (6.2) and non-natives (8.4). The standardized rates per thousand residents were 1.29, higher among males and non-natives. The non-natives are distinguished by a higher percentage of male, of clients of homes for minors/protected center, of patients with psychiatric drugs use. Minors born in Latin America had the highest proportion of AAI admissions and the highest standardized rates. Conclusions: AAI is increasing among Italian adolescents, particularly in the non-native population, and it is associated with illegal substance use. Differences emerge among the non-natives on the basis of their country of birth.

Background & Aims Nosocomial acute-on-chronic liver failure (nACLF) develops in at least 10% of patients with cirrhosis hospitalized for acute decompensation (AD), greatly worsening their prognosis. In this prospective observational study, we aimed to identify rapidly obtainable predictors at admission, which allow for the early recognition and stratification of patients at risk of nACLF. Methods A total of 516 consecutive patients hospitalized for AD of cirrhosis were screened: those who did not present ACLF at admission (410) were enrolled and surveilled for the development of nACLF. Results Fifty-nine (14%) patients developed nALCF after a median of 7 (IQR 4–18) days. At admission, they presented a more severe disease and higher degrees of systemic inflammation and anemia than those (351; 86%) who remained free from nACLF. Competing risk multivariable regression analysis showed that baseline MELD score (sub-distribution hazard ratio [sHR] 1.15; 95% CI 1.10–1.21; p ≪0.001), hemoglobin level (sHR 0.81; 95% CI 0.68–0.96; p = 0.018), and leukocyte count (sHR 1.11; 95% CI 1.06–1.16; p ≪0.001) independently predicted nACLF. Their optimal cut-off points, determined by receiver-operating characteristic curve analysis, were: 13 points for MELD score, 9.8 g/dl for hemoglobin, and 5.6x109/L for leukocyte count. These thresholds were used to stratify patients according to the cumulative incidence of nACLF, being 0, 6, 21 and 59% in the presence of 0, 1, 2 or 3 risk factors (p ≪0.001). Nosocomial bacterial infections only increased the probability of developing nACLF in patients with at least 1 risk factor, rising from 3% to 29%, 16% to 50% and 52% to 83% in patients with 1, 2 or 3 risk factors, respectively. Conclusions Easily available laboratory parameters, related to disease severity, systemic inflammation, and anemia, can be used to identify, at admission, hospitalized patients with AD at increased risk of developing nACLF. Lay summary More than 10% of patients with cirrhosis hospitalized because of an acute decompensation develop acute-on-chronic liver failure, which is associated with high short-term mortality, during their hospital stay. We found that the combination of 3 easily obtainable variables (model for end-stage liver disease score, leukocyte count and hemoglobin level) help to identify and stratify patients according to their risk of developing nosocomial acute-on-chronic liver failure, from nil to 59%. Moreover, if a nosocomial bacterial infection occurs, such an incidence proportionally increases from nil to 83%. This simple approach helps to identify patients at risk of developing nosocomial acute-on-chronic liver failure at admission to hospital, enabling clinicians to put in place preventive measures., Graphical Abstract Unlabelled Image, Highlights • ACLF complicates more than 10% of hospitalizations for acute decompensation of cirrhosis. • Easily available predictors of nosocomial ACLF are fundamental to implement appropriate preventive strategies. • MELD score, leucocyte count and hemoglobin can stratify patients according to their risk of developing nosocomial ACLF. • Further studies are required to validate these results and provide additional insights.

Background & Aims The electrocardiographic QT interval frequently is prolonged in patients with cirrhosis. Acute gastrointestinal bleeding further prolongs corrected QT (QTc) in patients with cirrhosis, which has been associated with an increased risk of death within 6 weeks. We aimed to confirm these findings and develop a mortality risk index that incorporates QTc. Methods We collected data from 274 patients with cirrhosis and acute gastrointestinal bleeding from any cause admitted to a hospital in Bologna, Italy, from January 2001 through December 2012 (training set). We used logistic regression analysis to identify patient factors associated with death within 6 weeks (6-week mortality). We validated our findings by using data from 200 patients with cirrhosis and gastrointestinal bleeding treated at 2 separate hospitals in Italy, from 2001 through 2016 and 2007 through 2012. Our primary aim was to confirm the prognostic effects of prolonged QTc in a large population of patients and develop a 6-week mortality risk score for acute gastrointestinal bleeding from any cause that incorporates the QTc interval. Results In the training set, QTc greater than 456 ms, the model for end-stage liver disease-sodium (MELD-Na) score, previous bleeding, and serum albumin concentration were associated independently with 6-week mortality. We combined these parameters to create a risk scoring system that we named MELD-Na acute gastrointestinal bleeding (MELDNa-AGIB). In the validation set, the MELDNa-AGIB identified patients who died within 6 weeks with an area under the receiver operating characteristic curve (AUROC) of 0.888; this value was higher than that of the MELD score (AUROC, 0.838; P = .031), MELD score with updated calibration (AUROC, 0.837; P = .029), Child–Turcotte–Pugh score (AUROC, 0.789; P = .004), D'Amico score (AUROC, 0.761; P = .003), and Augustin score (AUROC, 0.792; P = .001), with a net reclassification improvement better than the MELD-Na score (0.266; P = .045). In calibration, the MELDNa-AGIB produced a high score in the Hosmer–Lemeshow test (P = .947), which was superior to that of MELD-Na (P = .146). In the training set, only 6.3% of patients with MELDNa-AGIB scores of 4 or less died within 6 weeks. Among patients with a scores of 9, 16, and 25 or higher, 15.5%, 41.5%, and 81% or more patients died within 6 weeks, respectively. The probability of survival progressively and significantly decreased with increasing scores in the training and validation sets. Conclusions We confirmed QTc as an independent predictor of 6-week mortality in a large population of patients with cirrhosis and acute gastrointestinal bleeding. The combination of QTc, MELD-Na, previous bleeding, and serum albumin (the MELDNa-AGIB score) accurately determines the risk of 6-week mortality, providing timely identification of patients at very high risk of death.

Most hepatocellular carcinomas (HCCs) arise in the context of chronic liver disease and/or cirrhosis. Thus, chemoprevention in individuals at risk represents an important but yet unproven approach. In this study, we investigated the ability of microRNA (miRNA)-based molecules to prevent liver cancer development in a cirrhotic model. To this end, we developed a mouse model able to recapitulate the natural progression from fibrosis to HCC, and then we tested the prophylactic activity of an miRNA-based approach in the model. The experiments were carried out in the TG221 transgenic mouse, characterized by the overexpression of miR-221 in the liver and predisposed to the development of liver tumors. TG221 as well as wild-type mice were exposed to the hepatotoxin carbon tetrachloride (CCl4) to induce chronic liver damage. All mice developed liver cirrhosis, but only TG221 mice developed nodular lesions in 100% of cases within 6 months of age. The spectrum of lesions ranged from dysplastic foci to carcinomas. To investigate miRNA-based prophylactic approaches, anti-miR-221 oligonucleotides or miR-199a-3p mimics were administered to TG221 CCl4-treated mice. Compared to control animals, a significant reduction in number, size, and, most significantly, malignant phenotype of liver nodules was observed, thus demonstrating an important prophylactic action of miRNA-based molecules. In summary, in this article, we not only report a simple model of liver cancer in a cirrhotic background but also provide evidence for a potential miRNA-based approach to reduce the risk of HCC development.

For the ESGBIS/BICHROME study group., [Background] We analyzed the impact of continuous/extended infusion (C/EI) vs intermittent infusion of piperacillin-tazobactam (TZP) and carbapenems on 30-day mortality of patients with liver cirrhosis and bloodstream infection (BSI). [Methods] The BICRHOME study was a prospective, multicenter study that enrolled 312 cirrhotic patients with BSI. In this secondary analysis, we selected patients receiving TZP or carbapenems as adequate empirical treatment. The 30-day mortality of patients receiving C/EI or intermittent infusion of TZP or carbapenems was assessed with Kaplan-Meier curves, Cox-regression model, and estimation of the average treatment effect (ATE) using propensity score matching. [Results] Overall, 119 patients received TZP or carbapenems as empirical treatment. Patients who received C/EI had a significantly lower mortality rate (16% vs 36%, P = .047). In a Cox-regression model, the administration of C/EI was associated with a significantly lower mortality (hazard ratio [HR], 0.41; 95% confidence interval [CI], 0.11–0.936; P = .04) when adjusted for severity of illness and an ATE of 25.6% reduction in 30-day mortality risk (95% CI, 18.9–32.3; P < .0001) estimated with propensity score matching. A significant reduction in 30-day mortality was also observed in the subgroups of patients with sepsis (HR, 0.21; 95% CI, 0.06–0.74), acute-on-chronic liver failure (HR, 0.29; 95% CI, 0.03–0.99), and a model for end-stage liver disease score ≥25 (HR, 0.26; 95% CI, 0.08–0.92). At competing risk analysis, C/EI of beta-lactams was associated with significantly higher rates of hospital discharge (subdistribution hazard [95% CI], 1.62 [1.06–2.47]). [Conclusions] C/EI of beta-lactams in cirrhotic patients with BSI may improve outcomes and facilitate earlier discharge., J. R.-B. and P.

Between 14%-30% of the world's population is affected by alcohol use disorder (AUD), and excessive alcohol consumption represents the most common cause of liver disease in the western world. The clinical picture of alcoholic end-stage liver disease is rendered extremely complex, as manifestations such as alcohol withdrawal syndrome, craving and physical dependence, as well as extrahepatic alcohol-related diseases merge with the complications of advanced cirrhosis. This makes AUD recognition and assessment difficult and its management arduous as many drugs commonly used to treat complications such as alcohol withdrawal syndrome are often contraindicated by the presence of hepatic encephalopathy or hepatorenal syndrome. Reaching and maintaining abstinence represents the mainstay of managing patients with AUD and end-stage liver disease. Psychosocial interventions are an essential component of treatment to reach these goals. However, these interventions alone often prove insufficient in AUD patients and even more frequently in those with end-stage liver disease because of inadequate adherence due to poor functional and physical status. Pharmacological treatments need to be associated, but the available options are greatly limited in end-stage liver disease because many GABA-Ergic drugs can favor the development of hepatic encephalopathy, whereas drugs undergoing extensive liver metabolism should be avoided or used with the greatest caution. Because of these limitations, the management of end-stage AUD is extremely challenging and requires an integrated multidisciplinary approach.

Introduction and Aims The aim of this study was to investigate the mortality risk and to explore the presence of subjects more at risk of dying in a cohort of alcoholic individuals treated for alcohol dependence over a lengthy follow-up period. Design and Methods A total of 2363 subjects attending 10 centres for addiction treatment for alcohol dependence were recruited. Results During the 17 year follow-up period, 14.7% of the entire cohort died. Total standardised mortality rates (SMR) were higher in women (SMR = 5.94) as compared with men (SMR = 4.65). Higher SMRs were found for several diseases, for traumatic episodes (SMR = 6.65) and in younger patients (18–44 age group) (SMR = 8.16). Alcoholic women showed a higher survival rate as compared with men. In addition, a higher risk of death for men and unemployed subjects, with a progressive increase of risk in line with the increase of the age of admission to treatment, and with a progressive decrease of risk after 1 year from the beginning of the treatment, was also found. Discussion and Conclusions This study confirms that mortality risk in alcoholic individuals in treatment is higher in comparison with the general population. Moreover, alcoholics men, unemployed, >40 years at time of admission and during the first year of treatment are more at risk to die. Thus, much more attention to patients with these characteristics should be planned by the professional staff working in centres for addiction treatment.

Background Alcohol use disorders (AUD) are a frequent cause of admission to emergency departments (EDs) for acute alcohol intoxication (AAI). Patients with AUD present a higher risk of readmission to EDs for AAI than the general population, however, the distinction between sporadic AAI and AAI in the context of AUD in the ED setting is difficult. Aims To analyze the epidemiological characteristics of patients admitted to EDs because of AAI and to identify factors associated with repeated admissions in order to develop a risk stratification system for patients with AUD based on objective data that can be easily applied in an ED setting. Methods An observational retrospective study was performed. All patients with diagnosis of AAI at admission in 2014 were enrolled. Results Five hundred and sixty-five patients were enrolled, of which 92 (16%) were admitted more than once to the ED. At multivariate analysis, factors associated with readmission were past episodes of alcohol abuse, social discomfort, previous traumas and psychiatric disorders. Basing on this parameter, a risk-score for re-hospitalization was developed. This score has a high predictive power for the risk of readmission to the ED (AROC 0.837, 95%CI 0.808–0.866), moreover, the cumulative probability of readmission within one year, increased in parallel with score value, being highest in patients presenting 3 or more risk factors. Conclusion The present study demonstrates that several risk factors stratify the risk of re-hospitalization in patients admitted to EDs for AAI, allowing the identification of those presenting more severe conditions and who would likely benefit from multidisciplinary intervention.

Human serum albumin (HSA) undergoes several structural alterations affecting its properties in pro-oxidant and pro-inflammatory environments, as it occurs during liver cirrhosis. These modifications include the formation of albumin dimers. Although HSA dimers were reported to be an oxidative stress biomarker, to date nothing is known about their role in liver cirrhosis and related complications. Additionally, no high sensitive analytical method was available for HSA dimers assessment in clinical settings. Thus the HSA dimeric form in human plasma was characterized by mass spectrometry using liquid chromatography tandem mass spectrometry (LC-ESI-Q-TOF) and matrix assisted laser desorption time of flight (MALDI-TOF) techniques. N-terminal and C-terminal truncated HSA, as well as the native HSA, undergo dimerization by binding another HSA molecule. This study demonstrated the presence of both homo- and hetero-dimeric forms of HSA. The dimerization site was proved to be at Cys-34, forming a disulphide bridge between two albumin molecules, as determined by LC-MS analysis after tryptic digestion. Interestingly, when plasma samples from cirrhotic subjects were analysed, the dimer/monomer ratio resulted significantly increased when compared to that of healthy subjects. These isoforms could represent promising biomarkers for liver disease. Additionally, this analytical approach leads to the relative quantification of the residual native HSA, with fully preserved structural integrity.

IntroductionPatients with cirrhosis have a high risk of sepsis, which confers a poor prognosis. The systemic inflammatory response syndrome (SIRS) criteria have several limitations in cirrhosis. Recently, new criteria for sepsis (Sepsis-3) have been suggested in the general population (increase of Sequential Organ Failure Assessment (SOFA) ≥2 points from baseline). Outside the intensive care unit (ICU), the quick SOFA (qSOFA (at least two among alteration in mental status, systolic blood pressure ≤100 mm Hg or respiratory rate ≥22/min)) was suggested to screen for sepsis. These criteria have never been evaluated in patients with cirrhosis. The aim of the study was to assess the ability of Sepsis-3 criteria in predicting in-hospital mortality in patients with cirrhosis and bacterial/fungal infections.Methods259 consecutive patients with cirrhosis and bacterial/fungal infections were prospectively included. Demographic, laboratory and microbiological data were collected at diagnosis of infection. Baseline SOFA was assessed using preadmission data. Patients were followed up until death, liver transplantation or discharge. Findings were externally validated (197 patients).ResultsSepsis-3 and qSOFA had significantly greater discrimination for in-hospital mortality (area under the receiver operating characteristic (AUROC)=0.784 and 0.732, respectively) than SIRS (AUROC=0.606) (pConclusionsSepsis-3 criteria are more accurate than SIRS criteria in predicting the severity of infections in patients with cirrhosis. qSOFA is a useful bedside tool to assess risk for worse outcomes in these patients. Patients with Sepsis-3 and positive qSOFA deserve more intensive management and strict surveillance.

The aim of this study was to investigate the mortality risk and to explore the presence of subjects more at risk of dying in a cohort of alcoholic individuals treated for alcohol dependence over a lengthy follow-up period.A total of 2363 subjects attending 10 centres for addiction treatment for alcohol dependence were recruited.During the 17 year follow-up period, 14.7% of the entire cohort died. Total standardised mortality rates (SMR) were higher in women (SMR = 5.94) as compared with men (SMR = 4.65). Higher SMRs were found for several diseases, for traumatic episodes (SMR = 6.65) and in younger patients (18-44 age group) (SMR = 8.16). Alcoholic women showed a higher survival rate as compared with men. In addition, a higher risk of death for men and unemployed subjects, with a progressive increase of risk in line with the increase of the age of admission to treatment, and with a progressive decrease of risk after 1 year from the beginning of the treatment, was also found.This study confirms that mortality risk in alcoholic individuals in treatment is higher in comparison with the general population. Moreover, alcoholics men, unemployed,40 years at time of admission and during the first year of treatment are more at risk to die. Thus, much more attention to patients with these characteristics should be planned by the professional staff working in centres for addiction treatment.

Beside the regulation of fluid distribution, human serum albumin (HSA) carries other activities, such as binding, transport, and detoxification of many molecules. In patients with cirrhosis, HSA exhibits posttranscriptional alterations that likely affect its functions. This study aimed at identifying the structural HSA alterations occurring in cirrhosis and determining their relationship with specific clinical complications and patient survival. One hundred sixty-eight patients with cirrhosis, 35 with stable conditions and 133 hospitalized for acute clinical complications, and 94 healthy controls were enrolled. Posttranscriptional HSA molecular changes were identified and quantified by using a high-performance liquid chromatography/electrospray ionization mass spectrometry technique. Clinical and biochemical parameters were also recorded and hospitalized patients were followed for up to 1 year. Seven HSA isoforms carrying one or more posttranscriptional changes were identified. Altered HSA isoforms were significantly more represented in patients than in healthy controls. Conversely, the native, unchanged HSA isoform was significantly reduced in cirrhosis. Native HSA and most altered isoforms correlated with both Child-Pugh and Model for End-Stage Liver Disease scores. In hospitalized patients, oxidized and N-terminal truncated isoforms were independently associated with ascites, renal impairment, and bacterial infection. Finally, the native HSA and cysteinylated/N-terminal truncated isoforms were predictors of 1-year survival, with greater prognostic accuracy than total serum albumin concentration. Conclusions: Extensive posttranscriptional changes of HSA, involving several molecular sites and increasing in parallel with disease severity, occur in patients with cirrhosis. Altered isoforms are independently associated with specific clinical complications, whereas the residual, native HSA isoform independently predicts patient survival. These findings support the concept of the “effective albumin concentration,” which implies that the global HSA function is related not only to its serum concentration, but also to the preservation of its structural integrity.

MicroRNAs (miRNAs) constitute a large class of short RNAs (e.g., 20-24 nucleotides in length), whose main function is to posttranscriptionally regulate the expression of protein-coding genes. Their importance in tumorigenesis has been demonstrated over the past decade, and correspondingly, they have emerged as potential therapeutic molecules and targets. Liver cancer is one of the most common neoplastic diseases worldwide, and it currently has a poor prognosis owing to largely ineffective therapeutic options. Liver cancer is also an excellent model for testing miRNA-based therapy approaches as it can be easily targeted with the systemic delivery of oligonucleotides. In recent years, the role of miRNAs in hepatocellular carcinoma (HCC) has been established with molecular studies and the development of animal models. These studies have also provided the basis for evaluating the therapeutic potential of miRNAs, or anti-miRNAs. In general, the safety of miRNAs has been proven and antitumor activity has been observed. Moreover, because of the absence or presence of mild side effects, the prophylactic use of miRNA-based approaches may be foreseen.

BACKGROUND & AIMS: Bloodstream infections (BSIs) in cirrhotic patients are 10-fold more common than in non-cirrhotic patients and increasingly caused by resistant pathogens. We examined 162 BSI episodes in cirrhotic patients to describe the etiology and risk factors for 30-day mortality. METHODS: We retrospectively analyzed all consecutive BSIs in patients with liver cirrhosis at our 1350-bed teaching hospital (January 2008 to June 2012). Cox-proportional hazard regression was used to analyze the impact of disease and treatment-related variables on the crude 30-day mortality. RESULTS: BSI episodes were identified in 162 patients, including 29 mixed infections. Most of episodes were classified as hospital acquired or healthcare associated (93%). Gram-negative bacteria (GNB), Gram-positive bacteria and Candida spp. caused 64%, 38%, and 10% of episodes, respectively. GNB were classified as multi-drug resistant (MDR) and extensively drug resistant (XDR) in 25% and 21% of cases, respectively. The overall crude 30-day mortality rate was 29%. Four risk factors were independently associated with 30-day crude mortality: worsening of MELD score from baseline (the last MELD score available in the 2weeks prior BSI) to that at BSI onset (HR 1.11 per point increase, 95% CI 1.07-1.15, p

Background & Aims: In spite of the high incidence of hepatic encephalopathy (HE) in cirrhosis, there are few observational studies. Methods:We performed an analysis to define the characteristics of HE and associated features using the database of the Canonic Study. Clinical, laboratory and survival data of 1348 consecutive cirrhotic patients admitted with an acute decompensation were compared according to the presence (n = 406) or absence of HE and of acute-on-chronic liver failure (ACLF) (n = 301). Results: HE development was independently associated with previous HE episodes; survival probabilities worsen in relation to the presence and grade of HE. There were marked differences between HE associated (n = 174) and not associated (n = 286) to ACLF. HE not associated with ACLF occurred in older cirrhotics, inactive drinkers, without severe liver failure or systemic inflammatory reaction and in relation to diuretic use. In contrast, HE associated with ACLF occurred in younger cirrhotics, more frequently alcoholics, with severe liver failure and systemic inflammatory reaction, and in relation to bacterial infections, active alcoholism and/or dilutional hyponatremia. Prognosis was relatively preserved in the first and extremely poor in the second group. Independent risk factors of mortality in patients with HE were age, bilirubin, INR, creatinine, sodium, and HE grade. Conclusions: In cirrhosis, previous HE identifies a subgroup of patients that is especially vulnerable for developing new episodes of HE. The course of HE appears to be different according to the presence of ACLF.

Human serum albumin (HSA) is the most abundant circulating plasma protein. Besides a significant contribution to the osmotic pressure, it is also involved in the fine regulation of many other physiological processes, including the balance of the redox state, the inflammatory and/or immunological responses, and the pharmacokinetic and pharmacodynamics of many drugs. Growing evidence suggests that HSA undergoes structural and functional damage in diseases characterized by an enhanced systemic inflammatory response and oxidative stress, as it occurs in chronic liver disease. Based on their clinical relevance, this review provides a summary of the most common post-translational modifications affecting HSA structural integrity and functions and their clinical relevance in the field of liver disease. The review also provides a critical description of the analytical approaches employed for the investigation of conformational alterations and the identification/quantitation of specific post-translational modifications affecting HSA. Finally, the analytical methods available for the assessment of two of the most clinically relevant non-oncotic properties of HSA, namely the binding capacity and the antioxidant activity, are critically reviewed. Among the available techniques particular attention is given to those proposed for the in vitro and in vivo investigation of structurally modified albumin.

Heat stress has a major impact on veal calves welfare and productivity. Prolonged exposure to warm temperature is associated with several alterations of physiologic processes and increased systemic inflammation and oxidative stress. Bovine serum albumin (BSA) is the most abundant plasma protein and, besides the regulation of osmotic pressure, carries several additional functions, including antioxidant, immunomodulatory, binding and transport activities. Such non-oncotic properties are closely related to structural integrity of the circulating molecule and may be compromised in stressful microenvironments as it occurs in heat stressed animals. Thus, in the present study we developed and validated an LC–MS analytical technique for the characterization of circulating BSA microheterogeneity in veal calves exposed to heat stress. The method was specifically tailored to the structural characteristics of the BSA molecule as well as to the complexity of the biological samples, allowing the identification of several BSA isoforms, each characterized by a specific structural defect. The mass spectrometry based approach enabled the identification of BSA isoforms with reversible and irreversible oxidation and/or glycation and the native BSA, the only isoform endowed with structural and functional integrity. We found that, in veal calves, heat stress is associated to a significant reduction of the native BSA and to a significant increment of the reversibly and irreversibly oxidized BSA. Then, by monitoring the BSA microheterogeneity over a period of moderate heat stress, we found that the native BSA as well as the glycated BSA increased significantly during the recovery period. Based on our results the analysis of the BSA microheterogeneity could represent a novel biomarker for the assessment of animal welfare during environmental stressful conditions.
