Article Synopsis
  • The study focused on identifying unique metabolomic signatures in patients with porto-sinusoidal vascular disorder (PSVD) and cirrhosis to improve diagnosis.
  • Serum samples from healthy volunteers and patients with PSVD or cirrhosis were analyzed using advanced techniques like liquid chromatography-mass spectrometry, identifying significant metabolic changes linked to PSVD.
  • Machine learning models were developed to distinguish PSVD from cirrhosis and healthy controls; key metabolites like taurocholic acid showed strong potential for non-invasive diagnostic use.

Portal vein thrombosis (PVT) is a frequent event among patients with advanced liver disease, with a prevalence reaching up to 26% in those awaiting liver transplantation (LT). Extensive thrombosis affecting the mesenteric vein confluence correlates with increased morbidity and mortality post-LT, particularly when it impedes physiological anastomosis or contraindicates the LT. Current guidelines advocate for routine PVT screening in all potential liver transplant candidates and prompt treatment upon detection.

Article Synopsis
  • This study investigates the relationship between hepatic venous pressure gradient (HVPG) and direct portal pressure (DPP) in cirrhosis patients who still have esophageal varices (EV) after treatment to remove the underlying cause, even when HVPG is low (<10 mmHg).
  • Ten patients with hepatitis C virus (HCV) or alcohol-related cirrhosis were examined, showing that HVPG correlates well with portal pressure measurements but doesn't fully explain the persistence of varices post-treatment.
  • The research suggests that while HVPG reflects overall portal pressure accurately, the presence of varices after treatment needs further exploration, indicating a gap in understanding the benefits of treatment for patients with EV but low HVPG.

Acute variceal bleeding in cirrhosis represents a critical clinical event that significantly impacts patient prognosis, with mortality rates increasing further after a second episode. This underscores the need for immediate intervention and optimal prophylaxis. The creation of a transjugular intrahepatic portosystemic shunt (TIPS) has been proven to be highly effective for managing esophageal variceal bleeding.

Article Synopsis
  • Little research exists on the environmental risks of expired pesticides, prompting a study to assess the acute toxicity (LD50) of expired versus unexpired malathion, chlorpyrifos, and lambda-cyhalothrin in rats.
  • The study found that expired lambda-cyhalothrin was more toxic than its fresh counterpart, while malathion and chlorpyrifos showed reduced toxicity when expired; all formulations caused clinical toxicity signs in rats.
  • Residue analysis revealed higher concentrations of pesticides in the liver and kidneys after treatment, with significant decreases noted during recovery, indicating that expired pesticides may pose unique dangers that necessitate proper disposal to protect the environment.

Biallelic pathogenic variants in the essential DNA repair gene causes Fanconi anemia, complementation group FA-D1. Patients in this group are highly prone to develop embryonal tumors, most commonly medulloblastoma arising from the cerebellar granule cell progenitors (GCPs). GCPs undergo high proliferation in the postnatal cerebellum under SHH activation, but the type of DNA lesions that require the function of the BRCA2 to prevent tumorigenesis remains unknown.

Adenoviruses are a diverse group of viruses that can cause a variety of diseases in poultry, including respiratory and gastrointestinal infections. In turkeys (Meleagris gallopavo), adenoviruses commonly cause hemorrhagic enteritis and, rarely, inclusion body hepatitis. In this study, we investigated fowl adenoviruses (FAdVs) circulating in turkeys in Egypt.

Transjugular intrahepatic portosystemic shunt (TIPS), a highly effective procedure reducing portal hypertension, has been in use for over seven decades and is now a cornerstone in managing portal hypertension-related complications such as variceal bleeding and ascites. Historically, TIPS has dealt with two main challenges: ensuring stent patency and preventing post-TIPS hepatic encephalopathy. The introduction of PTFE-coated stents markedly reduced the risk of TIPS dysfunction and stent patency is no longer a major concern.

Background: In this study, we investigated the prevalence of respiratory viruses in four Hybrid Converter Turkey (Meleagris gallopavo) farms in Egypt. The infected birds displayed severe respiratory signs, accompanied by high mortality rates, suggesting viral infections. Five representative samples from each farm were pooled and tested for H5 & H9 subtypes of avian influenza viruses (AIVs), Avian Orthoavulavirus-1 (AOAV-1), and turkey rhinotracheitis (TRT) using real-time RT-PCR and conventional RT-PCR.

Background: The potential involvement of type 2 diabetes mellitus (T2DM) as a risk factor for colon cancer (CC) has been previously reported. Epigenetic changes, such as deregulation of long non-coding RNA (lncRNA) and microRNA (miR), have been linked to the advancement of CC; however, the effects of high glucose levels on their deregulation and, in turn, colon cancer remain unexplored.

Methods: Fifty patients had a dual diagnosis of CC and T2DM, and 60 patients with CC without diabetes mellitus were included in the study.

Doxorubicin (DOX)-induced cardiotoxicity (DIC) is a life-threatening clinical issue with limited preventive approaches, posing a substantial challenge to cancer survivors. The anthraquinone diacerein (DCN) exhibits significant anti-inflammatory, anti-proliferative, and antioxidant actions. Its beneficial effects on DIC have yet to be clarified.

Transjugular intrahepatic portosystemic shunt (TIPS) emerges as a key treatment for portal hypertension (PH) complications. While international guidelines provide clear indications for its use in cirrhosis, empirical knowledge is notably scarcer in non-cirrhotic PH, particularly in nonmalignant noncirrhotic portal vein thrombosis (NNPVT) and in patients with portosinusoidal vascular disorder (PSVD). Patients afflicted by these rare diseases exhibit distinct clinical profiles compared to their cirrhotic counterparts, often characterized by a younger age, predominantly preserved hepatic functionality even in cases of severe PH, and a higher propensity for extensive splanchnic thrombosis, which intricately complicates TIPS placement, posing unique challenges for its creation.

Background: Extracellular vesicles (EVs) modulate inflammation, coagulation and vascular homeostasis in decompensated cirrhosis.

Aim: To characterize the profile of plasmatic EVs in patients with decompensated cirrhosis and bacterial infections and evaluate the association between EVs and the development of hemostatic complications.

Methods: We measured the levels of EVs using high-sensitivity flow cytometry and phospholipid-dependent clotting time (PPL) in a prospective cohort of hospitalized patients with acutely decompensated cirrhosis with versus without bacterial infections.

Background & Aims: Porto-sinusoidal vascular disorder (PSVD) encompasses a group of liver diseases with vascular abnormalities that can cause portal hypertension in the absence of cirrhosis. The new diagnostic criteria allow for coexistence with other liver diseases, however its relationship with chronic hepatitis B (CHB) remains unclear. This study aimed to assess HBV prevalence in a PSVD cohort and evaluate its clinical impact.

  • This systematic review assesses the effectiveness of radiomics for noninvasively determining isocitrate dehydrogenase (IDH) status in grade 4 and lower-grade diffuse gliomas through a meta-analysis of 26 studies involving 3,280 patients.
  • The pooled sensitivity and specificity for detecting IDH mutations were found to be 79% and 80%, indicating good accuracy, but the overall study quality was low, raising concerns about potential bias.
  • Subgroup analyses revealed that lower-quality studies had a lower rate of false positives, and there were no significant differences in accuracy between grade 4 and lower-grade tumors or between studies using single versus multiple imaging sequences.

Portal hypertension (PH), defined as a pathological increase in the portal vein pressure, has different aetiologies and causes. Intrahepatic PH is mostly secondary to the presence of underlying liver disease leading to cirrhosis, characterized by parenchymal changes with deregulated accumulation of extracellular matrix and vascular abnormalities; liver sinusoidal endothelial cells and hepatic stellate cells are key players in PH progression, able to influence each other. However, PH may also develop independently of parenchymal damage, as occur in portosinusoidal vascular disorder (PSVD), a group of clinical and histological entities characterized by portal vasculature dysfunctions.
