Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an established technique for lung cancer staging and the diagnosis of mediastinal diseases. Recently, the paradigm of EBUS guided mediastinal sampling with conventional cytology has shifted over to histology specimens through the use of cryobiopsy. This case series explores the novel technique, key enablers, and potential advantages of endoscopic ultrasound with bronchoscope-guided transesophageal cryobiopsy (EUS-B-TEC).

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is commonly used to diagnose and stage lung cancer. In clinical practice, cytology specimens from EBUS-TBNA may be low in cellularity, especially with necrotic lesions. Endobronchial ultrasound-guided transbronchial mediastinal cryobiopsy (EBUS-TBMC) has recently become the preferred method for obtaining histology biopsy.

Various craniofacial syndromes cause skeletal malformations and are accompanied by neurological abnormalities at different levels, leading to tremendous biomedical, financial, social, and psychological burdens. Accumulating evidence highlights the importance of identifying and characterizing the genetic basis that synchronously modulates musculoskeletal and neurobehavioral development and function. Particularly, previous studies from different groups have suggested that neural EGFL-like-1 (Nell-1), a well-established osteochondrogenic inducer whose biopotency was initially identified in the craniofacial tissues, may also play a vital role in the central nervous system, particularly regarding neurological disorder pathologies.

Microgravity-induced bone loss results in a 1% bone mineral density loss monthly and can be a mission critical factor in long-duration spaceflight. Biomolecular therapies with dual osteogenic and anti-resorptive functions are promising for treating extreme osteoporosis. We previously confirmed that NELL-like molecule-1 (NELL-1) is crucial for bone density maintenance.

Article Synopsis
  • Esophageal squamous cell carcinoma (ESCC) is prevalent in sub-Saharan Africa, but there have been no extensive genetic studies focusing on African populations, despite significant findings in East Asian groups.
  • A genome-wide association study (GWAS) involving 1,686 African ESCC patients and 3,217 matched controls identified a significant risk locus near the FAM120A gene on chromosome 9 and a potential African-specific risk locus on chromosome 2 (MYO1B).
  • A meta-analysis combining African and Chinese data revealed shared and unique genetic risk factors for ESCC, highlighting the important genetic contributions to the disease in African populations.

Background: Sclerosing pneumocytoma is a benign tumor that occurs mostly in the lungs and very rarely in the middle mediastinum. It may be difficult to diagnose, as its radiological features and histologic heterogeneity mimic malignancy; therefore a histopathologic examination is required to establish a definitive diagnosis.

Case Presentation: The patient was a 52-year-old woman who was found to have a tumor in the middle mediastinum on a chest CT scan and was referred to our hospital for resection.

Background: In non-small cell lung cancer (NSCLC), there may be a relationship between programmed death-ligand 1 (PD-L1) expression, driver mutations and cigarette smoking.

Methods: In this single-center retrospective study, the relationship between common driver mutations (EGFR mutation and ALK rearrangement) and PD-L1 expression in advanced NSCLC according to the patients' smoking history was examined. Light, moderate and heavy smokers had smoked < 20, 20-39, and ≥ 40 pack-years, respectively.

Background: Cancer recurrence after curative cancer surgery significantly impacts patients and healthcare services. Before surgery, a small number of clinically undetectable circulating tumour cells are often present. The surgical stress response promotes the distribution and proliferation of circulating tumour cells leading to cancer recurrence and metastasis.

Introduction: Cognitive, behavioural, academic, mental health and social impairments are common following paediatric traumatic brain injury (TBI). However, studies are often reliant on small samples of children drawn from narrow age bands, and employ highly variable methodologies, which make it challenging to generalise existing research findings and understand the lifetime history of TBI.

Method And Analysis: This study will synthesise common data sets from national (Victoria, New South Wales, Queensland) and international (New Zealand) collaborators, such that common data elements from multiple cohorts recruited from these four sites will be extracted and harmonised.

Hyaluronic acid (HA) is highly elevated in breast cancers compared to normal breast tissue and is associated with increased tumor aggressiveness and poor prognosis. HA interacts with cell-trafficking CD44 receptors to promote tumor cell migration and proliferation and regulates both pro- and anti-inflammatory cytokine production through tumor-associated macrophages. The highly negative charge of HA enables its uptake of vast amounts of water that greatly increases the tumor interstitial fluidic pressure, which, combined with the presence of other extracellular matrix components such as collagen, results in tumor stroma with abnormal vasculature, hypoxia, and increased drug resistance.
