RESUMO

Conventional radiography is widely used for postmortem foetal imaging, but its role in diagnosing congenital anomalies is debated. This study aimed to assess the effectiveness of X-rays in detecting skeletal abnormalities and guiding genetic analysis and counselling. This is a retrospective analysis of all post-abortion diagnostic imaging studies conducted at a centre serving a population of over 300,000 inhabitants from 2008 to 2023. The data were analysed using descriptive statistics. X-rays of 81 aborted foetuses (total of 308 projections; mean: 3.8 projections/examination; SD: 1.79) were included. We detected 137 skeletal anomalies. In seven cases (12.7%), skeletal anomalies identified through radiology were missed by prenatal sonography. The autopsy confirmed radiological data in all cases except for two radiological false positives. Additionally, radiology failed to identify a case of syndactyly, which was revealed by anatomopathology. X-ray is crucial for accurately classifying skeletal abnormalities, determining the causes of spontaneous abortion, and guiding the request for genetic counselling. Formal training for both technicians and radiologists, as well as multidisciplinary teamwork, is necessary to perform X-ray examinations on aborted foetuses and interpret the results effectively.

RESUMO

Telemedical technologies provide significant benefits in sports for performance monitoring and early recognition of many medical issues, especially when sports are practised outside a regulated playing field, where participants are exposed to rapidly changing environmental conditions or specialised medical assistance is unavailable. We provide a review of the medical literature on the use of telemedicine in adventure and extreme sports. Out of 2715 unique sport citations from 4 scientific databases 16 papers met the criteria, which included all research papers exploring the use of telemedicine for monitoring performance and health status in extreme environments. Their quality was assessed by a double-anonymised review with a specifically designed four-item scoring system. Telemedicine was used in high-mountain sports (37.5%; n = 6), winter sports (18.7%; n = 3), water sports (25%; n = 4), and long-distance land sports (18.7%; n = 3). Telemedicine was used for data transfer, teleconsulting, and the execution of remote-controlled procedures, including imaging diagnostics. Telemedical technologies were also used to diagnose and treat sport-related and environmentally impacted injuries, including emergencies in three extreme conditions: high mountains, ultraendurance activities, and in/under the water. By highlighting sport-specific movement patterns or physiological and pathological responses in extreme climatic conditions and environments, telemedicine may result in better preparation and development of strategies for an in-depth understanding of the stress of the metabolic, cardiorespiratory, biomechanical, or neuromuscular system, potentially resulting in performance improvement and injury prevention.

RESUMO

BACKGROUND: The role of sarcopenia in predicting decompensation other than hepatic encephalopathy is unclear. We aimed to evaluate the prognostic role of sarcopenia, assessed by computed tomography (CT), in the development of ascites and mortality in patients with advanced chronic liver disease (ACLD) outside the liver transplantation (LT) setting. MATERIAL AND METHODS: We retrospectively evaluated ACLD patients with liver stiffness measurement (LSM) >10 kPa and an available CT scan within 6 months. Sarcopenia was defined as skeletal muscle index (SMI) <50 and <39 cm2/m2, respectively, in men and women. Competing risk regression models were used to assess the variables associated with the main outcomes. RESULTS: 209 patients were included in the final analysis and sarcopenia was present in 134 (64.1%). During a median follow-up of 37 (20-63) months, 52 patients developed ascites, 24 underwent LT, and 30 died. Sarcopenia was found a predictive factor of decompensation with ascites (SHR 2.083, 95%-CI: 1.091-3.978), independently from the features of clinically significant portal hypertension (LSM≥21 kPa or portosystemic shunts). Sarcopenia (SHR: 2.744, 95%-CI: 1.105-6.816) and LSM≥21 kPa (SHR: 3.973, 95%-CI: 1.548-10.197) were independent risk factors for increased mortality. CONCLUSIONS: Sarcopenia and portal hypertension are two major and independent risk factors for decompensation with ascites and mortality in cirrhotic patients outside the LT context.

RESUMO

BACKGROUND: The prognostic role of spontaneous portosystemic shunts (SPSS) has been poorly investigated. AIMS: To evaluate the impact of the presence of SPSS, as well as their characteristics, on the risk of decompensation. METHODS: This is a retrospective cohort study of 235 advanced chronic liver disease (ACLD) patients with available imaging examination, transient elastography, and upper endoscopy. ACLD was defined as liver stiffness measurement (LSM) >10 kPa. Competitive risk analyses were performed to identify the factors associated with the main outcome. RESULTS: SPSS were reported in 141 (60%) of the patients. Non-viral etiology was independently associated with SPSS presence [Odds-Ratio (OR): 2.743;95%-Interval-of-Confidence (IC):1.129-6.664]. During a follow-up of 37 (20-63) months, SPSS were found predictors of any decompensation type [Subhazard Ratio (SHR):2.264; 95%-IC:1.259-4.071], independently from a history of decompensation or high-risk-varices presence. The risk of complications was higher in patients with large (SHR: 3.775; 95%-IC: 2.016-7.070) and multiple (SHR:3.832; 95%-IC: 2.004-7.330) shunts, and in those with gastrorenal shunts (SHR:2.636; 95%-IC:1.521-4.569). CONCLUSIONS: The presence, size, and number of SPSS predict not only the risk of hepatic encephalopathy but that of any type of decompensation across all stages of cirrhosis. Future studies should explore the possibility of treating shunts to prevent decompensation.

RESUMO

OBJECTIVES: The primary end point was the compliance rate with guidelines. The secondaries were mortality, hospital stay, and costs. METHODS: This study included 1904 patients with acute pancreatitis (AP): group A, diagnosed before 2013, and group B, after 2013. RESULTS: The compliance rate was 0.6%. The compliance rates increased for fluid resuscitation (3.3% vs 13.7%, P < 0.001), for antibiotics use (21.9% vs 28.1%, P = 0.002), for oral feeding (55.0% vs 49.7%, P = 0.007), and for correct use of endoscopic retrograde cholangiopancreatography (ERCP) (83% vs 91.9%, P < 0.001). Compliance to severity assessment with computed tomography (odds ratio [OR], 0.4; P = 0.029), parenteral nutrition recommendations (OR, 0.3; P = 0.009), and early surgery (OR, 0.3; P = 0.010) reduced the mortality. Compliance to antibiotic therapy (OR, 0.6; P < 0.001), correct use of parenteral nutrition (OR, 0.3; P < 0.001), correct use of ERCP (OR, 0.5; P < 0.001), and early surgery (OR, 0.3; P = 0.010) reduced hospital stay. The compliance reduced the costs for parenteral nutrition (P < 0.001), correct use of ERCP (P = 0.011), and surgery (P = 0.010). CONCLUSIONS: The adherence to guidelines for AP was low. Compliance could reduce mortality, prolonged hospital stay, and costs.

RESUMO

PURPOSE: The aim of the present study was to propose and validate a standardized CT protocol for evaluating all the types of portosystemic collaterals (P-SC), including gastroesophageal varices and spontaneous portosystemic shunts (SPSS), and to evaluate the prognostic role of portal hypertension CT features for the prediction of the hepatic decompensation risk in cirrhotic patients. METHODS: A retrospective cohort study of 184 advanced chronic liver disease who underwent CT scan between January 2014 and December 2017. Patients with an interval > 6 months between the imaging, elastometric, endoscopic and biochemical evaluation were excluded, as well as patients with previous transjugular intrahepatic portosystemic shunt (TIPS), liver transplantation (LT) or terminal medical conditions. Data on liver disease history, co-morbidities, endoscopic and radiologic findings were collected. The incidence of hepatic decompensation and other events, such as portal vein thrombosis, HCC, TIPS placement, LT, death, and its cause, were also recorded. The procedure was performed at baseline and after the administration of contrast agent using a multiphasic technique and bolus tracking. Two senior radiologists working in different centres and a non-expert radiologist reviewed all CT examinations, to evaluate both intra-observer and inter-observer variability of the CT protocol and to obtain an external validation. The radiological variables were evaluated using both univariate and adjusted multivariate competing risk regression models. RESULTS: Both intra-observer and inter-observer agreement were excellent in detection and measurement of almost all types of P-SC. The presence of SPSS, a spleen diameter > 16 cm, a portal vein diameter > 17 mm and the presence of ascites resulted independent predictors of decompensation-free survival for cirrhotic patients and were incorporated in an easy-to-use score (AUROC = 0.799, p-value = 0.732) which can the risk of decompensation at 5 years, ranking it as low (11.3%), moderate (35.6%) or high (70.8%). CONCLUSIONS: The CT protocol commonly performed during the HCC surveillance program for cirrhotic patients is valid for detecting all types of P-SC. The radiological score identified to predict the decompensation-free survival for cirrhotic patients could be an easy-to-use clinical tool.

RESUMO

In adult patients, acute lymphoblastic leukemia (ALL) is a rare hematological cancer with a cure rate below 50% and frequent relapses. With traditional therapies, patients with relapsed or refractory (R/R) ALL have a survival that may be measured in months; in these patients, inotuzumab ozogamicin (IO) is an effective therapy. IO was linked to increased risk of veno-occlusive disease/sinusoid obstruction syndrome (VOD/SOS), liver injury, and various grade of liver-related complications during clinical trials and real-life settings; however, hepatologic monitoring protocol is not established in this population. In our institution, 21 patients who received IO (median of 6 doses of IO administered) for R/R ALL were prospectively followed for hepatologic surveillance, including clinical evaluation, ultrasonography, and liver stiffness measurement (LSM) biochemistry. After a median follow-up of 17.2 months, two SOS events were reported (both after allogeneic transplant) as IO potentially related clinically relevant adverse event. Mild alterations were reported in almost the totality of patients and moderate-severe liver biochemical alterations in a quarter of patients. Within biochemicals value, AST and ALP showed an augment related to IO administration. LSM linearly augmented for each IO course administered. Baseline LSM was related to liver-related changes, especially with the severity of portal hypertension (PH)-related complications. Pre-transplant LSM was higher in patients receiving IO when compared with a control cohort. PH-related complications were discovered in nearly 77% of patients, with clinically significant PH occurrence and development of ascites in 38% and 14%, respectively. This prospective experience constitutes the rationale to design a hepatologic monitoring program in patients receiving IO. LSM may be of pivotal importance in this program, constituting a rapid and effective screening that quantitatively correlates with liver alterations.

RESUMO

Portal hypertension is the main driver of complications in patients with advanced chronic liver disease (ACLD). In the last decade, many non-invasive tests, such us liver and spleen elastography, have been proposed and validated for the identification of patients with clinically significant portal hypertension (CSPH) and its complications, mainly hepatic decompensation and liver-related morbidity and mortality. Moreover, elastography accurately stratifies for the risk of HCC development, HCC recurrence and decompensation after liver surgery. Recent studies suggest a role of SSM in monitoring response to treatments and interventions in ACLD, such as viral eradication, non-selective beta-blockers and transjugular intrahepatic portosystemic shunt placement. However, one of the most indications to perform elastography in ACLD still remains the screening for esophageal varices. In fact, according to the Baveno VI consensus, liver stiffness measurement (LSM) <20 kPa and platelet count >150,000/mm3 can safely identify patients at low risk of varices requiring treatment (VNT) and could therefore avoid invasive upper invasive endoscopy; LSM>20-25 kPa can accurately rule-in CSPH in patients with viral etiology. Spleen stiffness measurement (SSM) is a direct surrogate of portal hypertension and has been demonstrated more accurate in predicting portal hypertension severity and VNT. A combined model including Baveno VI Criteria and SSM (≤46 kPa) can significantly increase the number of spared endoscopies (>40-50%), maintaining a low (<5%) of missed VNT.

RESUMO

Introduction: Sarcopenia is defined as loss of skeletal muscle mass, strength, and function, and it is associated with increased morbidity and mortality in patients with chronic liver disease.Areas covered: The aim of this review is to provide a detailed report on the pathophysiological mechanisms underlying sarcopenia in cirrhotic patients, the several imaging methods available for the assessment of sarcopenia and the clinical studies evaluating the prognostic role of sarcopenia presence in cirrhotic patients.Expert opinion: Sarcopenia pathogenesis is complex and multifaceted, as chronic catabolic conditions, increased energy expenditure, reduced appetite, side effects of multiple therapies, alterations in circulating levels of hormones, low protein synthesis, presence of ascites or portosystemic shunts are all factors contributing to muscle atrophy in cirrhotic patients. Computed tomography scan is the most validated method to evaluate muscle mass and quality. Sarcopenia is associated with a higher rate waitlist mortality, hepatic encephalopathy, and lower quality of life in patients with liver cirrhosis. Future studies should make an effort to unify and validate liver disease-specific cutoffs for the definition of sarcopenia.

RESUMO

To date, the only available treatment for celiac disease (CD) patients is a life-lasting gluten-free diet (GFD). Lack of adherence to the GFD leads to a significant risk of adverse health consequences. Food cross-contamination, nutritional imbalances, and persistent gastrointestinal symptoms are the main concerns related to GFD. Moreover, despite rigid compliance to GFD, patients struggle in achieving a full restoring of the gut microbiota, which plays a role in the nutritive compounds processing, and absorption. Pivotal studies on the supplementation of GFD with probiotics, such as Bifidobacterium and Lactobacilli, reported a potential to restore gut microbiota composition and to pre-digest gluten in the intestinal lumen, reducing the inflammation associated with gluten intake, the intestinal permeability, and the cytokine and antibody production. These findings could explain an improvement in symptoms and quality of life in patients treated with GFD and probiotics. On the other hand, the inclusion of prebiotics in GFD could also be easy to administer and cost-effective as an adjunctive treatment for CD, having the power to stimulate the growth of potentially health-promoting bacteria strains. However, evidence regarding the use of prebiotics and probiotics in patients with CD is still insufficient to justify their use in clinical practice.

RESUMO

Changes in body composition are associated with poor outcomes in cancer patients including hepatocellular carcinoma (HCC). Sarcopenia, defined as the loss of skeletal muscle mass, quality and function, has been associated with a higher rate of complications and recurrences in patients with cirrhosis and HCC. The assessment of patient general status before HCC treatment, including the presence of sarcopenia, is a key-point for achieving therapy tolerability and to avoid short- and long-term complications leading to poor patients' survival. Thus, we aimed to review the current literature evaluating the role of sarcopenia assessment related to HCC treatments and to critically provide the clinicians with the most recent and valuable evidence. As a result, sarcopenia can be predictive of poor outcomes in patients undergoing liver resection, transplantation and systemic therapies, offering the chance to clinicians to improve the muscular status of these patients, especially those with high-grade sarcopenia at high risk of mortality. Further studies are needed to clarify the predictive value of sarcopenia in other HCC treatment settings and to evaluate its role as an additional staging tool for identifying the most appropriate treatment. Besides, interventional studies aiming at increasing the skeletal muscle mass for reducing complications and increasing the survival in patients with HCC are needed.

RESUMO

Hepatocellular carcinoma (HCC) is one of the most common malignancies in the world and it is one of the main complications of cirrhosis and portal hypertension. Even in the presence of a well-established follow-up protocol for cirrhotic patients, to date poor data are available on predictive markers for primary HCC occurrence in the setting of compensated advanced chronic liver disease patients (cACLD). The gold standard method to evaluate the prognosis of patients with cACLD, beyond liver fibrosis assessed with histology, is the measurement of the hepatic venous pressure gradient (HVPG). An HVPG ≥10 mmHg has been related to an increased risk of HCC in cACLD patients. However, these methods are burdened by additional costs and risks for patients and are mostly available only in referral centers. In the last decade increasing research has focused on the evaluation of several, simple, non-invasive tests (NITs) as predictors of HCC development. We reviewed the currently available literature on biochemical and ultrasound-based scores developed for the non-invasive evaluation of liver fibrosis and portal hypertension in predicting primary HCC. We found that the most reliable methods to assess HCC risk were the liver stiffness measurement, the aspartate aminotransferase to platelet ratio index score and the fibrosis-4 index. Other promising NITs need further investigations and validation for different liver disease aetiologies.
