The purpose of the current review article is to present a comprehensive understanding regarding pros and cons of graphene related nanocomposites and to find ways in order to improve the performance of nanocomposites with new designs. Nanomaterials including GR are employed in industrial applications such as supercapacitors, biosensors, solar cells, and corrosion studies. The present article has been prepared in three main categories. In the first part, graphene types have been presented, as pristine graphene, graphene oxide and reduced graphene oxide. In the second part, nanocomposites with many graphene, inorganic and polymeric materials such as polymer/GR, activated carbon/GR, metal oxide/GR, metal/graphene and carbon fibre/GR have been investigated in more detail. In the third part, the focus in on the industrial applications of GR nanocomposite, including super capacitors, biosensors, solar cells, and corrosion protection studies.

Young adulthood is a developmental period from late adolescence to one's late twenties or early thirties. Prevalence studies internationally have reported that individuals in this age group tend to have the highest rates of problem gambling. However, much of the prevention work designed to minimize the risk of problem and disordered gambling has been primarily focused on school settings and aimed at high school students. The objective of this study was to summarize the existing literature on the effectiveness of prevention programs aimed at reducing the prevalence of gambling problems in young adults. A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Six electronic academic databases were consulted in order to examine the studies conducted during the last 20 years. After removing duplicates and adhering to the inclusion and exclusion criteria, nine studies were included in this review. All studies targeted college or university students and followed a selective or indicated prevention strategy. A Personalized Normative Feedback approach was incorporated in most of the studies, which had generally good results in reducing and/or minimizing at-risk or problem gambling. The limited number of studies included in this review highlights the need to address scientific quality standards before proceeding with the design, implementation and widespread dissemination of these preventive programs as well as the need to ensure the program's efficacy prior to implementation.

Concern exists in Europe about the possibility of importation of infectious diseases due to the recent influx of migrants and refugees after 2011. In this retrospective 6-year study, we examined the epidemiology of fever of unknown origin (FUO) in Greece over the past years. Forty-eight patients with classical FUO were included. The proportion of infectious causes of FUO (29.2%) was similar to previous studies in Greece and all infections were endemic to the area. Disease-related mortality was 12.5% and no deaths due to infection were recorded. In conclusion, none of the diagnosed infectious causes of FUO raised concerns about the possibility of imported diseases or pathogens. These results re-inforce the perception that migrants and refugees are not carriers of communicable diseases that can cause public health problems to European countries.

An array of sensors, including an HD camera mounted on a Fixed Underwater Observatory (FUO) were used to monitor a cold-water coral (Lophelia pertusa) reef in the Lofoten-Vesterålen area from April to November 2015. Image processing and deep learning enabled extraction of time series describing changes in coral colour and polyp activity (feeding). The image data was analysed together with data from the other sensors from the same period, to provide new insights into the short- and long-term dynamics in polyp features. The results indicate that diurnal variations and tidal current influenced polyp activity, by controlling the food supply. On a longer time-scale, the coral's tissue colour changed from white in the spring to slightly red during the summer months, which can be explained by a seasonal change in food supply. Our work shows, that using an effective integrative computational approach, the image time series is a new and rich source of information to understand and monitor the dynamics in underwater environments due to the high temporal resolution and coverage enabled with FUOs.
- A Stab in the Dark: A Case Report of an Atypical Presentation of Giant Cell Arteritis (GCA). [Case Reports]
- GGeriatrics (Basel) 2018 Jun 29; 3(3)
- CONCLUSIONS: This case highlights how a vasculitis can present with a range of non-specific symptoms that may resemble a fever of unknown origin (FUO)/sepsis that can lead to a delay in making the correct diagnosis. It also highlights the importance of considering a diagnosis of vasculitis in patients who present with a FUO where there is no clear focus of infection. Delays in diagnosis and management of these conditions can potentially lead to significant irreversible morbidity.

- Fever of unknown origin: a retrospective review of pediatric patients from an urban, tertiary care center in Washington, DC. [Journal Article]
- WJWorld J Pediatr 2019 Mar 19
- CONCLUSIONS: This study aligns with some of the most recent publications which report undiagnosed cases as the most common outcome in patients hospitalized with FUO. Understanding that, often no diagnosis is found may reassure patients, families, and clinicians. The cost associated with hospitalization for FUO may cause clinicians to reconsider inpatient admission for diagnostic work-up of fever, particularly given the evidence demonstrating that many patients are discharged without a diagnosis.
- Four-extremity venous duplex ultrasound for suspected deep venous thrombosis is an anachronism. [Journal Article]
- JVJ Vasc Surg Venous Lymphat Disord 2019; 7(3):325-332.e1
- CONCLUSIONS: FED for FUO is inefficient, given that DVT was rarely the proximate cause of fever. Acute upper extremity DVT was found only in patients with an upper extremity CVC, demonstrating that patients without upper extremity CVC do not benefit from upper extremity duplex ultrasound examination. Upper extremity DVT is usually line associated and dependent on the number of cumulative risk factors present, suggesting that only the extremity associated with the CVC in the right clinical context should be imaged. Lower extremity DVT is also dependent on the number of cumulative risk factors present, and testing should be reserved for patients according to the clinical context. Our results indicate that a restrictive strategy can reduce testing inefficiency and health care cost without compromising patients' safety.

- CONCLUSIONS: A changing pattern of diseases causing FUO during the examined periods was evident. Infections continue to be the most common cause but with decreasing incidence when compared to 20 year ago. Even nowadays clinical evaluation and follow-up still remain the vital diagnostic tools in determining the etiology of FUO.
