Background: Extended distribution refers to the practice whereby people who inject drugs pass on sterile injecting equipment to their networks and can be a means to access people who inject drugs who do not attend state-sanctioned needle and syringe programs. While it is legal, to possess a sterile syringe for the purpose of injecting drugs in New South Wales, Australia, it is a criminal offence to pass this equipment on for others to use. In 2013 a pilot project was established to trial the authorization of "extended" peer distribution. This research describes patterns of distribution among attendees participating in this trial.
Methods: A cross-sectional survey was conducted during one week in October 2014 of the trial with 200 clients. The survey focused on the extent, characteristics, and perceived risks and benefits of extended distribution practices within peer groups.
Results: Extended distribution is widespread, not in an organized or intentional manner but as a consequence of day-to-day drug using activities. The profiles of those who do and do not distribute were similar. Willingness to distribute small quantities of equipment to others was higher than willingness to distribute larger quantities, and willingness to distribute was related to perceived benefits of extended distribution. Police scrutiny was a key reason for not wanting to distribute.
Conclusion: Extended peer distribution is widespread though mostly not organized. This study supports the evidence that drug users act responsibly to prevent harm and promote the use of sterile equipment among their peers.

Background: Multiple Sulfatase Deficiency (MSD) is a rare inherited lysosomal storage disorder characterized by loss of function mutations in the SUMF1 gene that manifests as a severe pediatric neurological disease. There are no available targeted therapies for MSD.
Methods: We engineered a viral vector (AAV9/SUMF1) to deliver working copies of the SUMF1 gene and tested the vector in Sumf1 knock out mice that generally display a median lifespan of 10 days.

Purpose: This retrospective study aimed to investigate demographic characteristics, predisposing factors, and clinical outcomes in patients with parasitic keratitis.
Methods: Medical records of patients with molecularly confirmed Acanthamoeba or microsporidia, identified through corneal scraping specimens (collected between September 21, 2017, and June 27, 2023), were reviewed. Demographic data, clinical profiles, such as symptom duration before confirmed diagnosis, antiviral treatment pre-diagnosis, contact lens use, tap water and soil contamination, ocular trauma, and treatment regimens, were analyzed.

Dealing with radioactive waste, particularly from various industrial processes, poses significant challenges. This paper explores the use of lithium aluminate borate (Li-Al-B) glass matrix as an alternative method for immobilizing radioactive waste, focusing specifically on waste generated in tin smelting industries, known as tin slag. The study primarily concentrates on transforming tin slag, a byproduct abundant in Natural Occurring Radioactive Material (NORM), into a stable and safe form for disposal.

State estimation for large-scale non-Gaussian dynamic systems remains an unresolved issue, given nonscalability of the existing particle filter algorithms. To address this issue, this paper extends the Langevinized ensemble Kalman filter (LEnKF) algorithm to non-Gaussian dynamic systems by introducing a latent Gaussian measurement variable to the dynamic system. The extended LEnKF algorithm can converge to the right filtering distribution as the number of stages become large, while inheriting the scalability of the LEnKF algorithm with respect to the sample size and state dimension.

Traditional approaches have often focused on individual brain regions and connections that do not capture the topographic organization of forebrain connectivity. We performed co-injections of anterograde and retrograde tract tracers in rats to provide novel high-spatial resolution evidence of topographic connections that elaborate a previously identified closed-loop forebrain circuit implicated in affective and motivational processes.
