Sarcopenia evaluated by EASL/AASLD computed tomography-based criteria predicts mortality in patients with cirrhosis: A systematic review and meta-analysis.

Background & Aims: Sarcopenia is associated with increased morbidity and mortality in patients with cirrhosis, but its definition in current literature is very heterogeneous. We performed a systematic review and meta-analysis to assess the association between mortality and sarcopenia evaluated by computed tomography (CT) in patients with cirrhosis, both overall and stratified for the criteria used to define sarcopenia.

Methods: Medline, Embase, Scopus, and Cochrane Library were searched up to January 2023.

Combined Stellate Ganglion Blockade and Epidural Thoracic Anesthesia for the Management of Ventricular Storm: A Case Report.

The term "ventricular storm (VS)" is defined as the occurrence of two or more separate episodes of ventricular tachycardia or fibrillation (VT/VF) or three or more appropriate discharges of an implantable cardioverter defibrillator for VT/VF during a 24-h period. A patient in his early 40s was observed in the emergency department of our hospital and was admitted to the cardiac intensive care unit due to multiple episodes of VT. This led to the need for deep sedation with orotracheal intubation and mechanical ventilation.

[Robotic Colorectal Surgery: Analysis of the First Three Years of Activity in a Hospital of the Portuguese National Health Service].

Introduction: Minimally invasive surgery has been increasingly accepted and used in colorectal surgery. Several studies report that robotic surgery may provide advantages over 'conventional' laparoscopy, namely in rectal surgery. This paper provides an account of the first three years of experience with robotic surgery in the Unidade de Patologia Colorretal of the Unidade Local de Saúde S.

Advances in the Early Warning of Shellfish Toxification by .

In Western Europe, the incidence of DST is likely the highest globally, posing a significant threat with prolonged bans on shellfish harvesting, mainly caused by species of the dinoflagellate genus . Using a time series from 2014 to 2020, our study aimed (i) to determine the concentration of in water at which shellfish toxin levels could surpass the regulatory limit (160 µg OA equiv kg) and (ii) to assess the predictability of toxic events for timely mitigation actions, especially concerning potential harvesting bans. The analysis considered factors such as (i) overdispersion in the data, (ii) distinct periods of presence and absence, (iii) the persistence of cells, and (iv) the temporal lag between cells in the water and toxins in shellfish.

Improving primary prophylaxis of variceal bleeding by adapting therapy to the clinical stage of cirrhosis. A competing-risk meta-analysis of individual participant data.

Background & Aims: Non-selective β-blockers (NSBBs) and endoscopic variceal-ligation (EVL) have similar efficacy preventing first variceal bleeding. Compensated and decompensated cirrhosis are markedly different stages, which may impact treatment outcomes. We aimed to assess the efficacy of NSBBs vs EVL on survival in patients with high-risk varices without previous bleeding, stratifying risk according to compensated/decompensated stage of cirrhosis.

Clear cell carcinoma of the ovary: Clues for radiologists to perform a correct diagnosis.

Ovarian clear cell carcinoma (OCCC) is an uncommon high-grade primary epithelial ovarian cancer, covering about 10-12 % of all ovarian malignancies. It has a strong association with endometriosis. OCCC diagnosis, at advanced stages, has an aggressive biological behaviour, and the therapeutic strategies for ovarian OCCC are somehow different from other ovarian carcinomas.

Transjugular intrahepatic portosystemic shunt in patients with hepatocellular carcinoma: A systematic review.

Background/aims: Transjugular intrahepatic portosystemic shunts (TIPS) in patients with hepatocellular carcinoma (HCC) may improve access to curative therapies, treat portal hypertension (PH)-related complications without worsening liver function, and increase overall survival. Data on the efficacy and safety of TIPS to treat PH complications in HCC patients, as well as the HCC treatment response, were evaluated.

Methods: Studies reporting efficacy in controlling bleeding/ascites or response to HCC therapy, safety, and survival in patients with HCC and TIPS were searched systematically on PubMed and Embase.

Alcohol-related liver disease phenotype impacts survival after an acute variceal bleeding episode.

Background & Aims: Alcohol-related hepatitis (AH) encompasses a high mortality. AH might be a concomitant event in patients with acute variceal bleeding (AVB). The current study aimed to assess the prevalence of AH in patients with AVB and to compare the clinical outcomes of AH patients to other alcohol-related liver disease (ALD) phenotypes and viral cirrhosis.

Studying the Influence of Multisensory Stimuli on a Firefighting Training Virtual Environment.

How we perceive and experience the world around us is inherently multisensory. Most of the Virtual Reality (VR) literature is based on the senses of sight and hearing. However, there is a lot of potential for integrating additional stimuli into Virtual Environments (VEs), especially in a training context.

Bivalve Shellfish Safety in Portugal: Variability of Faecal Levels, Metal Contaminants and Marine Biotoxins during the Last Decade (2011-2020).

Bivalves are a high-value product whose production has markedly increased, reaching 9863 tonnes in Portugal in 2021. Bivalves' habitats-lagoons, estuaries and coastal waters-are exposed to biological and anthropogenic contaminants, which can bioaccumulate in these organisms and pose a significant public health risk. The need to obtain a safe product for human consumption led to the implementation of standardised hygiene regulations for harvesting and marketing bivalve molluscs, resulting in routine monitoring of bivalve production areas for microbial quality, metal contaminants, and marine biotoxins.

Mycophenolate mofetil as second line treatment in autoimmune hepatitis - A retrospective single center analysis.

Background: Most patients with autoimmune hepatitis respond to standard treatment with steroids and azathioprine. While the disease is usually fatal if untreated, patients who respond well to therapy have an excellent prognosis. Nevertheless, second-line treatment is necessary in approximately 20% of patients, due to either intolerance or insufficient response to first line treatment.

Non-invasive tools for compensated advanced chronic liver disease and portal hypertension after Baveno VII - an update.

Non-invasive tests (NITs) and liver stiffness measurement (LSM) in particular, have entered clinical practice over 20 years ago as point-of-care tests to diagnose liver fibrosis in patients with compensated chronic liver disease. Since then, NITs use has evolved thanks to a large number of studies in all major etiologies of liver disease, and they have become important tools to stratify the risk of portal hypertension and liver-related events. The Baveno VII consensus workshop provided several novel recommendations regarding the use of well-established and novel NITs in the specific setting of portal hypertension screening, diagnosis and follow-up.

Hepatic encephalopathy is not a contraindication to pre-emptive TIPS in high-risk patients with cirrhosis with variceal bleeding.

Background: A pre-emptive transjugular intrahepatic portosystemic shunt (pTIPS) reduces mortality in high-risk patients with cirrhosis (Child-Pugh C/B+active bleeding) with acute variceal bleeding (AVB). Real-life studies point out that <15% of patients eligible for pTIPS ultimately undergo transjugular intrahepatic portosystemic shunt (TIPS) due to concerns about hepatic encephalopathy (HE). The outcome of patients undergoing pTIPS with HE is unknown.

Liver Abscess Complicated with an Inflammatory Myofibroblastic Tumor.

Inflammatory myofibroblastic tumors have a wide spectrum of biological behaviour and are composed of inflammatory cells and myofibroblastic spindle cells. Tumors may infrequently involve the liver. Imaging findings are non-specific.

Potential vascular damage by posterior dislocation of sternoclavicular joint.

A 34-year-old man was admitted for surgical treatment following traumatic posterior sternoclavicular joint dislocation and anterior mediastinum hematoma with compression of brachiocephalic vein (A, B). Intra-operative positioning consid- ered access for possible sternotomy and control of upper vena cava territory in case of bleeding from venous confluent (C). Patient was submitted to open reduction of sternoclavicular joint through an oblique supraclavicular incision (D), fixation with high strength orthopedic suture (E), mediastinal drainage and closure with absorbable suture (F).

Investigational drugs in early clinical development for portal hypertension.

Introduction: Advanced chronic liver disease is considered a reversible condition after removal of the primary etiological factor. This has led to a paradigm shift in which portal hypertension (PH) is a reversible complication of cirrhosis. The pharmacologic management of PH is centered on finding targets to modify the natural history of cirrhosis and PH.

Carvedilol reduces the risk of decompensation and mortality in patients with compensated cirrhosis in a competing-risk meta-analysis.

Background & Aims: Whether non-selective β-blockers can prevent decompensation of cirrhosis warrants clarification. Carvedilol might be particularly effective since its intrinsic vasodilatory activity may ameliorate hepatic vascular resistance, a major mechanism of portal hypertension in early cirrhosis. We assessed whether carvedilol may prevent decompensation and improve survival in patients with compensated cirrhosis and clinically significant portal hypertension (CSPH).

Using Heart Rate Variability for Comparing the Effectiveness of Virtual vs Real Training Environments for Firefighters.

The use of Virtual Reality (VR) technology to train professionals has increased over the years due to its advantages over traditional training. This paper presents a study comparing the effectiveness of a Virtual Environment (VE) and a Real Environment (RE) designed to train firefighters. To measure the effectiveness of the environments, a new method based on participants' Heart Rate Variability (HRV) was used.
