Diesel engines serve many purposes in modern oil and gas extraction activities. Diesel particulate matter (DPM) emitted from diesel engines is a complex aerosol that may cause adverse health effects depending on exposure dose and duration. This study reports on personal breathing zone (PBZ) and area measurements for DPM (expressed as elemental carbon) during oil and gas extraction operations including drilling, completions (which includes hydraulic fracturing) and servicing work. Researchers at the National Institute for Occupational Safety and Health (NIOSH) collected 104 full-shift air samples (49 PBZ and 55 area) in Colorado, North Dakota, Texas, and New Mexico during a four year period from 2008-2012 The arithmetic mean (AM) of the full shift TWA PBZ samples was 10 µg/m(3); measurements ranged from 0...

PURPOSE: An ostomy adversely affects health-related quality of life (HRQOL) in a diverse population of cancer survivors and their caregivers. Hit-or-miss ostomy care, nurse counseling, and community referral have been the primary modes of self-management education and support in the peri-operative setting. Few evidence-based, systematic ostomy self-management programs are available to ensure optimal post-operative care. This paper describes the study design of a telehealth-based Ostomy Self-management Training (OSMT) program for cancer survivors and their caregivers...

CONTEXT: Clinicians draw upon experiential knowledge to manoeuvre difficult conversations, using tacit knowledge that is difficult to explicitly teach. Instead, learners are taught to communicate through role-play and checklists, both of which are approaches that may fail during moments of clinical complexity. We know that difficult conversations may provoke anxiety in learners, but we know little about how they learn to navigate them. Without a deeper understanding, we may fail to equip learners with the skills to manoeuvre these conversations in practice...

Dear Editors,We read with interest the article by Di Franco and co-workers (1). The introduction of prostatic magnetic resonance and the relative fusion-biopsy have not yet allowed the expected improvements in prostate biopsy. To our knowledge, there are no works that demonstrate the superiority of fusion techniques on the remaining ultrasound guided prostate biopsies that are still the widely used in the diagnosis of prostate cancer. Furthemore, these technologies are expensive exams and they are not yet available in all centers, especially in those minors...

Sensory processing difficulties are common among many special needs children, especially those with autism spectrum disorder (ASD). The sensory sensitivities often result in interference of daily functioning and can lead to social isolation for both the individual and family unit. A quality improvement (QI) project was undertaken within a local zoo to systematically implement a sensory training program targeted at helping special needs individuals with sensory challenges, including those with ASD, Down's syndrome, attention-deficit/hyperactivity disorder, and speech delay...

BACKGROUND: Tanzania is a low income, East African country with a severe shortage of human resources for health or health workers. This shortage threatens any gains the country is making in improving maternal health outcomes. This paper describes a partnership between Touch Foundation and NYU Rory Meyers College of Nursing - Global, aimed at improving clinical mentorship and capacity among nurses and midwives at two rural hospitals in the Tanzanian Lake Zone Region. Clinical mentoring capacity building and supportive supervision of staff has been shown to be a facilitator of retaining nurses and would be possible to acquire and implement quickly, even in a context of low resources and limited technology...

Supervised learning algorithms in a spiking neural network either learn a spike-train pattern for a single neuron receiving input spike-train from multiple input synapses or learn to output the first spike time in a feedforward network setting. In this paper, we build upon spike-event based weight update strategy to learn continuous spike-train in a spiking neural network with a hidden layer using a dead zone on-off based adaptive learning rate rule which ensures convergence of the learning process in the sense of weight convergence and robustness of the learning process to external disturbances...

BACKGROUND: Femoroacetabular impingement syndrome (FAI), a hip disorder affecting active young adults, is believed to be a leading cause of hip osteoarthritis (OA). Current management approaches for FAI include arthroscopic hip surgery and physiotherapy-led non-surgical care; however, there is a paucity of clinical trial evidence comparing these approaches. In particular, it is unknown whether these management approaches modify the future risk of developing hip OA. The primary objective of this randomised controlled trial is to determine if participants with FAI who undergo hip arthroscopy have greater improvements in hip cartilage health, as demonstrated by changes in delayed gadolinium-enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC) index between baseline and 12 months, compared to those who undergo physiotherapy-led non-surgical management...

Intraflagellar transport (IFT) is essential for the elongation and maintenance of eukaryotic cilia and flagella. Due to the traffic jam of multiple trains at the ciliary tip, how IFT trains are remodeled in these turnaround zones cannot be determined by conventional imaging. Using Photogate, we visualized the full range of movement of single IFT trains and motors in Chlamydomonas flagella. Anterograde trains split apart and IFT complexes mix with each other at the tip to assemble retrograde trains. Dynein-1b is carried to the tip by kinesin-II as inactive cargo on anterograde trains...
