Objectives: Nicotine usage is known to increase postoperative complications; however, studies show that the general population believes that non-tobacco nicotine delivery devices are a safer option compared to tobacco-based nicotine products. This study evaluates postoperative complications between non-tobacco nicotine dependent and non-nicotine dependent patients for intramedullary nailing in intertrochanteric femur fractures.

Methods: Utilizing the TriNetX database, we retrospectively examined postoperative outcomes in patients aged 18 to 90 who underwent intramedullary nailing for intertrochanteric femur fractures between November 21, 2013, and November 21, 2023.

Article Synopsis
  • Myelodysplastic neoplasms (MDS) and chronic myelomonocytic leukemia (CMML) are diseases caused by mutations in blood stem cells that affect blood production.
  • Hypomethylating agents (HMAs) can help manage these conditions without needing to eliminate all mutated cells, possibly improving the function of the remaining stem cells.
  • The study analyzed the mutations in different blood cell types before and after treatment to understand how these mutated stem cells behave and contribute to better blood counts following HMA therapy.

We have isolated a chlorophyll--containing cyanobacterium from the intertidal field site at Moss Beach, on the coast of Central California, USA, where Manning and Strain (1943) originally discovered this far-red chlorophyll. Here, we present the cyanobacterium's environmental description, culturing procedure, pigment composition, ultrastructure, and full genome sequence. Among cultures of far-red cyanobacteria obtained from red algae from the same site, this strain was an epiphyte on a brown macroalgae.

With the continuing development of affordable immersive virtual reality (VR) systems, there is now a growing market for consumer content. The current form of consumer systems is not dissimilar to the lab-based VR systems of the past 30 years: the primary input mechanism is a head-tracked display and one or two tracked hands with buttons and joysticks on hand-held controllers. Over those 30 years, a very diverse academic literature has emerged that covers design and ergonomics of 3D user interfaces (3DUIs).

Mammalian sexual development commences when fetal bipotential progenitor cells adopt male Sertoli (in XY) or female granulosa (in XX) gonadal cell fates. Differentiation of these cells involves extensive divergence in chromatin state and gene expression, reflecting distinct roles in sexual differentiation and gametogenesis. Surprisingly, differentiated gonadal cell fates require active maintenance through postnatal life to prevent sexual transdifferentiation and female cell fate can be reprogrammed by ectopic expression of the sex regulator DMRT1.

The use of Virtual Reality (VR) technology combined with 360-degree images and videos provide an opportunity for teachers to bring students into the classroom even when they are located somewhere else. During the COVID-19 lockdown and pandemic, with students across the world forced into home-based learning via remote teaching, a VR classroom shows potential as a tool for adding depth to their learning. The possibility of immersing students in a virtual environment could provide an answer to motivation and engagement issues for today's students as well as a solution to some of the current constraints faced by teachers.

This work addresses cybersickness, a major barrier to successful long-exposure immersive virtual reality (VR) experiences since user discomfort frequently leads to prematurely ending such experiences. Starting from sensory conflict theory, we posit that if a vibrating floor delivers vestibular stimuli that minimally match the vibration characteristics of a scenario, the size of the conflict between the visual and vestibular senses will be reduced and, thus, the incidence and/or severity of cybersickness will also be reduced. We integrated a custom-built, computer-controlled vibrating floor in our VR system.

Introduction: Variation in test ordering is a major issue in Australia and globally with significant financial and clinical impacts. There is currently a lack of research identifying and remediating variation in the use of pathology tests in emergency departments (EDs). In 2019, NSW Health Pathology introduced the Pathology Atlas of Variation that uses a data-driven tool (the Atlas Analytical Model) to investigate test order variation across New South Wales (NSW) and engage with local health districts (LHDs) to reduce variation.
