Primary intestinal lymphangiectasia (PIL) is a rare protein-losing gastroenteropathy characterized by diffuse or localized ectasia of the enteric lymphatics, which can be accompanied by lymphatic abnormalities in other parts of the body. This condition results in hypoalbuminemia, hypogammaglobulinemia, and lymphopenia due to the abnormal leakage of lymphatic fluid into the gastrointestinal tract. As there are no specific serological or radiological tests available, the gold standard for diagnosing intestinal lymphangiectasia is endoscopic examination with histopathological examination of intestinal biopsy specimens.

Perlecan is a widely distributed, modular, and multifunctional heparan sulfate proteoglycan, which facilitates cellular communication with the extracellular environment to promote tissue development, tissue homeostasis, and optimization of biomechanical tissue functions. Perlecan-mediated osmotic mechanotransduction serves to regulate the metabolic activity of cells in tissues subjected to tension, compression, or shear. Perlecan interacts with a vast array of extracellular matrix (ECM) proteins through which it stabilizes tissues and regulates the proliferation or differentiation of resident cell populations.

Background: Evidence suggests that cognitive bias modification of interpretations (CBM-I) is effective in modifying interpretation biases and has a small effect on reducing anxiety in children and adolescents. However, most evidence to date is based on studies which report anxiety or general distress using Likert-type or Visual Analogue Scales, which are useful but do not reliably index symptoms of clinical importance. This meta-analysis aimed to establish the effects of CBM-I for children and adolescents on both anxiety and depression using psychometrically validated symptom measures, as well as state negative affect and negative and positive interpretation bias.

Objectives: It is now recognized that blood brain barrier (BBB) leakage occurs in cerebral small vascular disease (CSVD) and plays a significant role in the pathophysiology of vascular dementia. We hypothesized that genetic polymorphisms of junctional adhesion molecule-A (JAM-A) (which may result in compromised structure of tight junction proteins that form the BBB) in combination with cerebrovascular risk factors hypertension, lipid disorders, and type 2 diabetes may result in BBB leakage and increase the individual's risk of CSVD-related dementia.

Methods: In this case-control study, 97 controls with a mean Mini-Mental State Exam (MMSE) score of 29 and 38 CSVD-related vascular dementia participants (mean MMSE score of 19) were recruited.

Article Synopsis
  • The global rise in aging populations is linked to a higher incidence of Alzheimer's disease (AD) and its socioeconomic impacts, driven largely by abnormal amyloid-β (Aβ) metabolism.
  • Current treatments focusing on Aβ removal have shown limited cognitive benefits, highlighting the complexity of AD's causes, which include a range of factors like tau accumulation, neuroinflammation, and vascular dysfunction.
  • To effectively treat AD, extensive research is needed on neurodegeneration mechanisms, identifying intervention targets, and developing combinatorial treatment strategies, with the overarching goal of reversing cognitive decline through the Alzheimer's Disease Neuroprotection Research Initiative.

Average volume-assured pressure support (AVAPS) mode has been available since 2009 and allows the ventilator to deliver a constant pre-set tidal volume by automatically adjusting the inspiratory pressures within a set range. Data in AVAPS mode use is limited in both paediatric populations, and in patients who are ventilated through a tracheostomy. This case series reports on the successful use of AVAPS mode in four paediatric patients with tracheostomy ventilation.

Objective: Whilst microdiscectomy is an excellent reliever of pain for recalcitrant lumbar disc herniation (LDH), it has a high failure rate over time due to the ensuing reduction in mechanical stabilization and support of the spine. One option is to clear the disc and replace it with a nonhygroscopic elastomer. Here, we present the evaluation of biomechanical and biological behavior of a novel elastomeric nucleus device (Kunovus disc device [KDD]), consisting of a silicone jacket and a two-part in situ curing silicone polymer filler.

  • A systematic review and meta-analysis investigated the link between retinal imaging features and Alzheimer's disease (AD), focusing on studies that defined AD based on brain amyloid beta status.
  • Thirty-eight studies showed weak associations, indicating that retinal changes like nerve fiber layer thinning and increased foveal avascular zone may be related to AD, though these findings were inconsistent.
  • The study highlights challenges in interpreting retinal imaging as AD biomarkers due to small sample sizes and differences in imaging techniques, suggesting the need for standardized methods in future research.

Intervertebral disc degeneration and how it leads to low back pain.

JOR Spine

March 2023

Raymond Purves Bone and Joint Research Laboratory Kolling Institute, Sydney University Faculty of Medicine and Health, Northern Sydney Area Health District, Royal North Shore Hospital Sydney New South Wales Australia.

The purpose of this review was to evaluate data generated by animal models of intervertebral disc (IVD) degeneration published in the last decade and show how this has made invaluable contributions to the identification of molecular events occurring in and contributing to pain generation. IVD degeneration and associated spinal pain is a complex multifactorial process, its complexity poses difficulties in the selection of the most appropriate therapeutic target to focus on of many potential candidates in the formulation of strategies to alleviate pain perception and to effect disc repair and regeneration and the prevention of associated neuropathic and nociceptive pain. Nerve ingrowth and increased numbers of nociceptors and mechanoreceptors in the degenerate IVD are mechanically stimulated in the biomechanically incompetent abnormally loaded degenerate IVD leading to increased generation of low back pain.

Animal models have been invaluable in the identification of molecular events occurring in and contributing to intervertebral disc (IVD) degeneration and important therapeutic targets have been identified. Some outstanding animal models (murine, ovine, chondrodystrophoid canine) have been identified with their own strengths and weaknesses. The llama/alpaca, horse and kangaroo have emerged as new large species for IVD studies, and only time will tell if they will surpass the utility of existing models.
