Background: Primary hepatic neuroendocrine tumors (PHNETs) are rare, accounting for approximately 0.3 % of all neuroendocrine tumors (NETs) and are often difficult to diagnose due to their nonspecific symptoms and imaging features. Standard diagnostic and treatment protocols are lacking due to their rarity, but imaging and immunohistochemistry (IHC) remain key tools for diagnosis.

The hAβ-KI and APP-KI are two amyloid models that harbor mutations in the endogenous mouse App gene. Both hAβ-KI and APP-KI mice contain a humanized Aβ sequence, and APP-KI mice carry three additional familial AD mutations. We herein report that the Aβ levels and Aβ42/Aβ40 ratio in APP-KI homozygotes are dramatically higher than those in hAβ-KI homozygotes at 14 months of age.

Article Synopsis
  • The study investigates well-differentiated low-grade lung neuroendocrine tumors (LNETs), focusing on their classification and unique molecular profiles beyond the typical and atypical categories.
  • Researchers used genomic techniques to reveal three distinct regulatory subtypes of LNETs, each characterized by specific transcription factors and differentiation signals: "proneuronal," "luminal-like," and "HNF+."
  • Targeting the FGFR signaling pathway in the HNF+ subtype showed promise for reducing tumor growth, highlighting potential new therapeutic approaches for treating these tumors.

Cystic Fibrosis (CF) is a complex disorder that requires multidisciplinary expertise for effective management. The GALAXY study estimated the prevalence of constipation to be about 25% among People with Cystic Fibrosis (PwCF), identifying it as one of the common gastrointestinal (GI) symptoms within this patient population. Quality of Life (QoL) assessments uncovered high patient dissatisfaction, highlighting the imperative need for enhanced treatment strategies.

Article Synopsis
  • Multi-drug resistant (MDR) E. coli is a significant public health issue, especially in developing regions like the global south, with travelers spreading it to other areas.
  • A study in Punjab, Pakistan, involved 494 outpatients and 423 community members, analyzing the genetic diversity of E. coli and its antimicrobial resistance (AMR) by collecting and sequencing stool samples, resulting in 5,247 genomes from 1,411 samples.
  • The research found that the genetic lineages and AMR profiles of E. coli in the Punjabi population differed notably from those in high-income countries, and antibiotic use was linked to increased prevalence of MDR strains, highlighting the need for ongoing regional genomic surveillance to understand and manage this

Background: Stereotactic body radiation therapy (SBRT) is often delivered in patients with oligometastatic disease (OMD). However, the specific subset of patients with polymetastatic non-small cell lung cancer (NSCLC) on novel systemic therapies who develop induced oligopersistant disease (OpersisD) or oligoprogressive disease (OprogD), as defined by the European Organisation for Research and Treatment of Cancer (EORTC) OMD classification, has not been well described. This study explores the outcomes of patients treated with this strategy.

Fabry Disease (FD) is a rare lysosomal storage disorder caused by mutations in the gene on the X chromosome, leading to a deficiency in α-galactosidase A (AGAL) enzyme activity. This leads to the accumulation of glycosphingolipids, primarily globotriaosylceramide (Gb3), in vital organs such as the kidneys, heart, and nervous system. While FD was initially considered predominantly affecting males, recent studies have uncovered that heterozygous Fabry women, carrying a single mutated gene, can manifest a wide array of clinical symptoms, challenging the notion of asymptomatic carriers.

Recent developments in networked and smart sensors have significantly changed the way Structural Health Monitoring (SHM) and asset management are being carried out. Since the sensor networks continuously provide real-time data from the structure being monitored, they constitute a more realistic image of the actual status of the structure where the maintenance or repair work can be scheduled based on real requirements. This review is aimed at providing a wealth of knowledge from the working principles of sensors commonly used in SHM, to artificial-intelligence-based digital twin systems used in SHM and proposes a new asset management framework.

The COVID-19 pandemic has created an urgency to study the host gene response that leads to variable clinical presentations of the disease, particularly the critical illness response. miRNAs have been implicated in the mechanism of host immune dysregulation and thus hold potential as biomarkers and/or therapeutic agents with clinical application. Hence, further analyses of their altered expression in COVID-19 is warranted.
