    Background/Objective. In 2015, the Centers for Medicare and Medicaid Services (CMS) announced coverage for annual lung cancer screening (LCS) with low dose computed tomography (LDCT) for individuals who are 55 to 77 years of age, have \u3e 30 pack years of smoking history, and undergo shared decision making (SDM) prior to screening. Most referrals for LCS are initiated in primary care. Currently, little is known about how primary care physicians view SDM and barriers in practice to SDM about LCS. This study aimed to gather information to help fill these knowledge gaps. Methods. I worked with senior leadership in the Department of Medicine to identify a set of internal medicine physicians at Thomas Jefferson University (TJU) and contacted them via email requesting their participation in an interview about SDM in LCS. I developed an interview guide that included questions about the following: understanding of SDM, perceptions about SDM in LCS, and receptivity to use of an online decision support intervention (DSI). I completed in-person, audio recorded interviews, which were transcribed for analysis. I then analyzed the interview transcripts using NVivo qualitative analysis software. Results. Nine physicians were interviewed from a pool of twenty-three physicians over a period of three weeks. With regards to understanding of SDM, physicians were in agreement that SDM is a joint decision based on a discussion about the risks and benefits of an intervention that considers patient values and medical status. Physician perceptions of SDM in LCS was influenced by patient comorbidities, LCS controversies and complexity, and limited office time. Receptivity to using an online DSI was generally positive and particularly favored its patient education component and easing of physician workload. Conclusions. Observations from this study highlight a common general understanding of SDM, yet mixed approaches to SDM in LCS. Strong support also exists for a DSI that educates patients about LCS and saves physicians time. Future steps include interviewing a set of family medicine physicians to investigate potential differences in viewpoints compared to internal medicine physicians

    Attitude of Syrian students toward GAD patients: An online cross-sectional study

    Generalized Anxiety Disorder (GAD) is a prevalent condition and a significant cause of mental disability and poor quality of life. People with GAD have chronic worrying, restlessness, and discrimination from the general public; Little is known about the stigmatizing attitudes toward people with GAD among Syrian students. The questionnaires contained demographic data about age, gender, social status, personal stigma toward GAD scale, perceived stigma toward GAD scale, social distance with those with GAD, the participants' usual source of their knowledge about GAD, helpful interventions, and supporting information. A total of 1,370 replies were collected, but only 1,358 were used for analysis as 12 participants declined to complete the survey. About 44.1% of participants agreed that people with GAD could snap out of the problem, most of them being females (32.4% of the total population). Compared to medical students, more non-medical students (7.1% of the total population) believed that anxiety is a sign of personal weakness. This study demonstrated that Syrian college students showed a high level of stigmatizing and socially distancing attitudes toward people with GAD, particularly female and non-medical students

    <p>We report the development and optimisation of an assay for quantitating iron from iron oxide nanoparticles in biological matrices by using ferene-s, a chromogenic compound. The method is accurate, reliable and can be performed with basic equipment common to many laboratories making it convenient and inexpensive. The assay we have developed is suited for quantitation of iron in cell culture studies with iron oxide nanoparticles, which tend to manifest low levels of iron. The assay was validated with standard reference materials and with inductively coupled plasma-mass spectrometry (ICP-MS) to accurately measure iron concentrations ∼1 × 10<sup>−6</sup> g in about 1 × 10<sup>6</sup> cells (∼1 × 10<sup>−12</sup> g Fe per cell). The assay requires preparation and use of a working solution to which samples can be directly added without further processing. After overnight incubation, the absorbance can be measured with a standard UV/Vis spectrophotometer to provide iron concentration. Alternatively, for expedited processing, samples can be digested with concentrated nitric acid before addition to the working solution. Optimization studies demonstrated significant deviations accompany variable digestion times, highlighting the importance to ensure complete iron ion liberation from the nanoparticle or sample matrix to avoid underestimating iron concentration. When performed correctly, this method yields reliable iron ion concentration measurements to ∼2 × 10<sup>−6</sup> M (1 × 10<sup>−7</sup> g/ml sample).</p
