Background The emergence of the COVID-19 and its consequences has led to fears, worries, and anxiety among individuals worldwide. The present study developed the Fear of COVID-19 Scale (FCV-19S) to complement the clinical efforts in preventing the spread and treating of COVID-19 cases. Methods The sample comprised 717 Iranian participants. The items of the FCV-19S were constructed based on extensive review of existing scales on fears, expert evaluations, and participant interviews. Several psychometric tests were conducted to ascertain its reliability and validity properties. Results After panel review and corrected item-total correlation testing, seven items with acceptable corrected item-total correlation (0.47 to 0.56) were retained and further confirmed by significant and strong factor loadings (0.66 to 0.74). Also, other properties evaluated using both classical test theory and Rasch model were satisfactory on the seven-item scale. More specifically, reliability values such as internal consistency (α = .82) and test-retest reliability (ICC = .72) were acceptable. Concurrent validity was supported by the Hospital Anxiety and Depression Scale (with depression, r = 0.425 and anxiety, r = 0.511) and the Perceived Vulnerability to Disease Scale (with perceived infectability, r = 0.483 and germ aversion, r = 0.459). Conclusion The Fear of COVID-19 Scale, a seven-item scale, has robust psychometric properties. It is reliable and valid in assessing fear of COVID-19 among the general population and will also be useful in allaying COVID-19 fears among individuals. © Springer Science+Business Media, LLC, part of Springer Nature 2020.This study investigated elementary school children's development of monitoring and control when learning from texts. Second (N = 138) and fourth (N = 164) graders were tested in the middle (T1) and end (T2) of the school year. The study focused on the cross-sectional and longitudinal development of monitoring and control, and aimed to investigate the development of metacognition for two test formats. After reading expository texts, children completed a comprehension test consisting of open-ended and true-false questions. They monitored their test performance by making confidence judgments, and controlled performance by deciding whether to maintain or withdraw their given answers. SJN 2511 Overall, monitoring and control accuracy was higher for open-ended questions than for true-false questions. For open-ended questions, results indicated higher metacognitive accuracy for fourth graders than second graders. No such age effects were found for monitoring and control for true-false questions. Longitudinally, children of both age groups improved their monitoring and control accuracy from T1 to T2, for open-ended and true-false questions. For both test types, improvement mainly occurred for the monitoring and controlling of incorrect, rather than correct answers. Additionally, the results indicated inter-individual stability of performance, but no stability of monitoring and control accuracy over time. The findings indicate that developmental as well as task-related factors affect children's metacognitive accuracy. © The Author(s) 2019, corrected publication 2019.Following the completion of the Human Genome Project (HGP) in 2003, advances in DNA sequencing technologies further popularized the field of genomics and brought its social ramifications to the fore. Scholars across disciplines recently voiced serious concerns about the re-emergence of genomic research that might be used to justify racism. In this piece, I trace the history of attempts to biologize the concept of race and its diffused presence in today's genomic research. I then include a brief analysis inspired by concepts from the field of Science and Technology Studies (STS) to suggest selected ways to produce better scientific knowledge. The text highlights historic landmarks of interest to science practitioners curious about the ways science of the past co-shapes science of the present. I then argue that science has never been isolated from the socio-political climate it is produced in; instead, it has been morphed by its surroundings and historically used as a potent tool to justify systemic oppression.

With the introduction of both targeted and immunotherapies there have been dramatic improvements in the care of patients with metastatic melanoma. With these new therapies being increasingly offered to patients with stage III metastatic melanoma and stage IV disease, radiological surveillance of melanoma has become a widely used method of monitoring melanoma patients for early locoregional and distant metastasis. However, concerns have been raised about risk of false positive results, which patients to consider radiological surveillance for, and at what intervals to do so. To date, there are no published review articles on the topic of radiological surveillance in melanoma patients identified in the MEDLINE database. A comprehensive literature review was performed by searching the MEDLINE database to review all published works on this topic. This article aims to present an extensive review of literature surrounding radiological surveillance in melanoma patients, a discussion of controversies, and recommendations for surveillance modalities.

The immune system can be broadly divided into an effector arm responsible for fighting infections and cancer and a regulatory arm that reduces autoreactivity and maintains immune homeostasis. Cutaneous autoimmunity develops when the equilibrium between the effector arm and regulatory arm of the immune system is disrupted. Recent insights into the inflammatory pathways that are overactive in some cutaneous autoimmune diseases have led to therapies targeting the effector arm of the immune system with greater treatment efficacy than previously used broad immunosuppressants. The current paradigm of inhibiting excessive immune activation for treating cutaneous autoimmunity will be discussed including cytokine blockade, cellular depletion, intracellular signaling blockade and costimulatory blockade. Despite the success of this approach many cutaneous autoimmune diseases lack a clearly delineated pathway to target and therefore new strategies are needed.
