Phytoseiid mites are key predators in agricultural crops. However, not all species regulate pest populations below economic thresholds, and therefore knowledge of which species are associated with particular crops aids pest control recommendations. Surveys of 12 crops across six geographical regions of California demonstrated that phytoseiid species varied by crop and geographical location, with subtropical crops exhibiting the lowest species diversity and grape the greatest. The western predatory mite, Galendromus occidentalis, long cited as a dominant species in California crops, was not found to be the major species in most situations. Euseius stipulatus, a species introduced in the 1970s, was found in the surveyed crops in many areas of the state and appears to be displacing E. hibisci along the south coast.

No evidence for automatic response activation with target onset in the avatar-compatibility task
Authors: Böffel C. , Müsseler J.
Published: June 2020

When people take the perspective of an avatar and perform a stimulus-response compatibility task, they generally show the same compatibility effects that are expected from the avatar’s position instead of their own. In this study, we investigated if these effects are caused by automatic response activation, a concept featured in dual-route models of stimulus-response compatibility. In two experiments we asked 24 participants each to perform a compatibility task from an avatar’s point of view. We introduced a delay between the presentation of the target and the avatar in half of the trials so that the participants had to wait until the avatar appeared to select the correct response. Because the automatic response activation is known to decay quickly, its influence is eliminated in this condition. In contrast to the prediction by the automatic response activation account, we observed a larger compatibility effect in the delayed condition with orthogonal (Experiment 1) and parallel (Experiment 2) stimulus-response pairings. Additionally, distributional analyses of the compatibility effects did not support the automaticity predictions. We conclude that these results call into question the role of automatic response activation for spatial compatibility in general and perspective-based compatibility effects in particular.

Martin Heidegger's Philosophy on the Pages of a Modern Russian Philosophical Journal: from Retrospection to Perspective
Authors: Romanenko Anton
Published: June 2020

In the paper was made an attempt to establish the specificity of studying Heidegger’s philosophical heritage within the frame of scientific discourse on pages of the journals «Epistemology & Philosophy of Science», «Problems of philosophy» and offer it interpretation. The author notes the presence of research interest to Martin Heidegger’s philosophical heritage on the pages of journal «Epistemology & Philosophy of Science», in context of the comparison with publications in «Problems of philosophy» denotes it as «low», which could be explained by the thematic scope of the journal and specificity of philosophical language of German philosopher. In this paper was considered the issue of prospects in appealing by authors of publications to the philosophy of Heidegger as a consequence of the immanent features of the development of the philosophy of science.

FACTORS DETERMINING OF OPERATIVE REDUCTION IN ACUTE INTUSSUSCETION OF CHILDREN

Background: Intussusception is the common cause of small intestinal obstruction in children under two years old. Late diagnosis can lead to a potentially worse condition. This prospective study aims to describe the clinical manifestation and develop the conservative management protocol for acute ileocaecal intussusception in children undertwo years old.
Methods: This prospective study was carried out in 118 consecutive patients under two years old. Patients presented with symptoms and signs of acute intestinal obstruction and diagnosis of ileocaecal intussusception confirmed by ultrasound were included in this study. All the patients were managed with either pneumatic reduction or operation.
Results: There were 70 boys and 48 girls ranging in age from three months to two years with a median of 12.5 months. Clinical presentation included abdominal pain (100%), vomiting (82.2%), bloody stool (11.9%) and a palpable mass (43.2%). Patients hospitalized with the symptoms and signs less than 24 hours were accounted for 80.5% of cases. The overall success rate of pneumatic reduction was 98.3%.
Late hospital admission (≥ 24 hours from illness onset), bloody stool and presenting with the classic triad of symptoms of intussusception were found as the factors which correlated to the surgical management outcome. All patients were well recovery without any complication. The median of postoperative hospital stay was two days for pneumatic reduction group and six days for operation group.
Conclusion: Early diagnosis of intussusception contributes the success of pneumatic reduction and reduces the requires of surgical intervention.
Key words: intussusception, pneumatic reduction, surgical intervention.

DOES ENVIRONMENTAL, SOCIAL AND GOVERNANCE PERFORMANCE INFLUENCE ECONOMIC PERFORMANCE?
Authors: Cek Kemal , Eyupoglu Serife
Published: June 2020

The purpose of this paper is to evaluate the influence of environmental, social and
governance performance on the economic performance of the Standard & Poor’s 500 companies. Structural
equation modeling and linear regression have been utilized to measure the overall and individual influence
of environmental, social and governance (ESG) performance on economic performance using longitudinal data
comprising the years from 2010 to 2015. The overall ESG model had a significant relationship on economic
performance. Furthermore, the findings of this study show that social and governance performance
significantly affects economic performance in all regression models. However, environmental performance
failed to show a significant relationship. The research contributes to the literature by providing insights
for investors, managers and employees about the influence of ESG performance on company performance.
THE EFFECT OF DISCRETIONARY ACCRUALS ON FIRM GROWTH. EMPIRICAL EVIDENCE FOR SMES FROM EMERGING EUROPE
Authors: Anton Sorin Gabriel , Carp Mihai
Published: June 2020

The aim of the paper is to assess the effect of discretionary accruals on firm growth while controlling
for firm characteristics and macroeconomic environment. Employing a large sample of 1.105 young and high-growth firms (gazelles)
from 15 emerging European countries over the period 2006–2014, it has been found that the discretionary accruals negatively
influence firm growth. The empirical results suggest that discretionary accruals are used as earnings management tools and
this practice is more used over the high-growth period (2006–2009), with negative effects on future performance. Furthermore,
the results of the quantile regression employed in the whole period suggest that the earnings management practices have a negative
effect on firm growth. The results prove to be robust for different estimation approaches and different sub-samples of gazelles.
The findings provide empirical evidence for the need for more detailed information provided by firms on the origin of the accruals,
as well as for the use in the performance analysis of some indicators that eliminate the influence of accruals, such as cash flow
based ratios.

Published: June 2020

The Vela and Puppis A supernova remnants (SNRs) comprise a large emission region of ∼8° diameter in the soft X-ray sky. The HaloSat CubeSat mission provides the first soft X-ray (0.4–7 keV) observation of the entire Vela SNR and Puppis A SNR region with a single pointing and moderate spectral resolution. HaloSat observations of the Vela SNR are best fit with a two-temperature thermal plasma model consisting of a cooler component with

keV in collisional ionization equilibrium and a hotter component with

keV in nonequilibrium ionization. Observations of the Puppis A SNR are best fit with a single-component plane-parallel shocked plasma model with

keV in nonequilibrium ionization. For the first time, we find the total X-ray luminosities of both components of the Vela SNR spectrum in the 0.5–7 keV energy band to be

erg s−1 for the cooler component and

erg s−1 for the hotter component. We find the total X-ray luminosities of the Vela and Puppis A SNRs to be

erg s−1 and

erg s−1.

Published: June 2020

Quasar proximity zones at

correspond to overdense and overionized environments. Galaxies found inside proximity zones can therefore display features that would otherwise be masked by absorption in the intergalactic medium. We demonstrate the utility of this quasar-galaxy synergy by reporting the discovery of the first three “proximate Lyα emitters” (LAEs) within the proximity zone of quasar J0836+0054 at z = 5.795 (Aerith A, B, and C). Aerith A, located behind the quasar with an impact parameter

pkpc, provides the first detection of an Lyα transverse proximity effect. We model the transmission and show that it constrains the onset of J0836's quasar phase to

in the past. The second object, Aerith B at a distance

pkpc from the quasar, displays a bright and broad double-peaked Lyα emission line. The peak separation implies a low ionizing

. We fit the Lyα line with an outflowing shell model, finding a typical central density

, outflow velocity

km s−1, and gas temperature

compared to

analog LAEs. We detect object Aerith C via an Lyα emission line at z = 5.726. This corresponds with the edge of the quasar’s proximity zone (

), suggesting that the proximity zone is truncated by a density fluctuation. Via the analyses conducted here, we illustrate how proximate LAEs offer unique insight into the ionizing properties of both quasars and galaxies during hydrogen reionization.
Arp 220: New Observational Insights into the Structure and Kinematics of the Nuclear Molecular Disks and Surrounding Gas

Published: June 2020

ALMA cycle 3 observations of 12CO J = 3 → 2, 13CO J = 4 → 3, SiO J = 8 → 7, and HCN J = 5 → 4 are presented. Significant extended emission is detected in 12CO J = 3 → 2 with a morphology that is indicative of m = 2 tidal features, suggesting gas inflow. In addition, outflows for both nuclei are found in 12CO J = 3 → 2. Significant SiO absorption is detected in the western nucleus. HCN that is morphologically distinct from CO is detected in both nuclei. These observations are compared to non-LTE radiative transfer models created using the Line Modeling Engine for simple gas dynamics to gain insight into how physical parameters, such as rotational velocity, turbulent velocity, gas temperature, dust temperature, and gas mass, can reproduce the observed kinematic and spatial features. The eastern nucleus is found to be best modeled with an inclusion of a temperature asymmetry from one side of the disk to the other. It is also found that the western nucleus is optically thick even in the less abundant species of 13CO, absorbing significant amounts of continuum radiation.

We collected over 6000 high-resolution spectra of four dozen field RR Lyrae (RRL) variables pulsating either in the fundamental (39 RRab) or in the first overtone (9 RRc) mode. We measured radial velocities (RVs) of four strong metallic and four Balmer lines along the entire pulsational cycle and derived RV amplitudes with accuracies better than 1–2 km s−1. The new amplitudes were combined with literature data for 23 RRab and 3 RRc stars (total sample of 74 RRLs), which allowed us to investigate the variation of the Bailey diagram (photometric amplitude versus period) when moving from optical to mid-infrared bands and to recast the Bailey diagram in terms of RV amplitudes. We found that RV amplitudes for RRab are minimally affected by nonlinear phenomena (shocks) and multiperiodicity (Blazhko effect). The RV slope (logP–A(V

r
)) when compared with the visual slope (logP–A(V)) is shallower, and the dispersion, at fixed period, decreases by a factor of two. We constructed homogeneous sets of horizontal branch evolutionary models and nonlinear, convective pulsation models of RRLs to constrain the impact of evolutionary effects on their pulsation properties. Evolution causes, on the Bailey diagram based on RV amplitudes, a modest variation in pulsation period and a large dispersion in amplitude. The broad dispersion in period of the Bailey diagram is mainly caused by variation in RRL intrinsic parameters (stellar mass, chemical composition). Empirical evidence indicates that RV amplitudes are an optimal diagnostic for tracing the mean effective temperature across the RRab instability strip.

En este artículo se estima el impacto que tienen las características de las viviendas alicantinas de segunda mano, en el precio de venta. Para desarrollar este trabajo, se ha utilizado información procedente de los portales inmobiliarios, que ofrecen datos relativos a cualidades que presentan las viviendas, el edificio, la situación geográfica y los precios de venta. El análisis se centra en la provincia de Alicante, utilizándose una regresión hedónica en la que las características que presentan las viviendas y la ubicación actúan como variables independientes y el precio de venta como dependiente. Los resultados muestran diferencias significativas en los precios de venta de las viviendas en función de las características y la ubicación, sugiriendo unos precios mayores para las viviendas situadas en las comarcas litorales del norte de Alicante, o para las que tienen piscina, jardín o garaje. Sin embargo, las situadas al sur o en el interior muestran un menor precio.

De esta manera, los esfuerzos de las instituciones no acreditadas no están bien coordinados y se diluyen en la distribución de sus relaciones colaborativas.
Universidades en Google: hacia un modelo de análisis multinivel del posicionamiento web académico
Authors: Gonzalez-Llinares Javier , Font-Julián Cristina I. , Orduña-Malea Enrique
Published: June 2020

Se propone un modelo de análisis del posicionamiento web de universidades basado en un vocabulario de palabras clave categorizadas según las distintas misiones universitarias, que se aplica a una universidad (Universitat Politècnica de València) para comprobar su idoneidad. A partir de un vocabulario de 164 palabras clave se construyeron 290 consultas web que fueron ejecutadas en Google, recopilando los 20 primeros resultados obtenidos para cada consulta. Los resultados confirman que las universidades obtienen un posicionamiento web variable en función de la dimensión vinculada a la consulta web y que las páginas web vinculadas a la docencia (especialmente Grados) son las que mejor posicionan, incluso para consultas web orientadas a investigación. Con todo, se observa un posicionamiento bajo no sólo para la UPV sino para las universidades públicas presenciales españolas (sólo el 27% del total de resultados en el Top 20 corresponde a alguna de estas universidades). Se concluye que el análisis multinivel es necesario para estudiar el posicionamiento web de las universidades y que el modelo propuesto es viable y escalable. No obstante, se han identificado ciertas limitaciones (dependencia del vocabulario utilizado y alta variabilidad de datos) que deben tenerse en cuenta en el diseño de este tipo de modelos de análisis.
Environmental and Biological Factors Influence Migratory Sea Lamprey Catchability: Implications for Tracking Abundance in the Laurentian Great Lakes
Authors: Lewandoski Sean A. , Bravener Gale A. , Hrodey Peter J. , Miehls Scott M.
Published: June 2020

Sea Lamprey Petromyzon marinus population trends in the Great Lakes are tracked by trapping migratory adults in tributaries and using mark-and-recapture techniques to estimate abundance. Understanding what environmental and biological factors influence Sea Lamprey capture in tributaries is crucial to developing efficient trapping methods and reliable abundance estimates. We analyzed data from trapping sites located on eight Great Lakes tributaries using Cormack–Jolly–Seber models and examined how water temperature, discharge, sex, and length influenced Sea Lamprey apparent survival and capture probability. Sea Lamprey apparent survival was negatively associated with water temperature in all tributaries. Additionally, the odds of small Sea Lamprey (≤ 45 cm) remaining available to capture were 39% less (95% CI: 63% decrease–1% increase) than large (> 45 cm) lamprey odds. We used these observed relationships to investigate if bias in abundance estimates using the pooled-Petersen estimator and Jolly–Seber models was expected to be similar across trapping locations or influenced by variable environmental conditions and biological traits. Pooled-Petersen abundance estimates had a positive bias when we generated data sets from simulated populations with empirical relationships between environmental characteristics and catchability. The degree of bias depended upon changes in stream warming patterns and was not consistent among trapping locations. Jolly–Seber models using data from either weekly batch-marked or uniquely marked individuals generated abundance estimates with low bias when data quality was high, but performed poorly in scenarios with few recaptured Sea Lamprey. This research can promote improved Sea Lamprey monitoring efforts by providing insight into the reliability of the pooled-Petersen abundance estimator as a tool for tracking Sea Lamprey populations and demonstrating the limitations of adopting more robust methods when data are sparse.
Robust Output Only Health Monitoring of Steel Railway Bridges
Authors: Rageh Ahmed , Linzell Daniel , Lopez Samantha , Eftekhar Azam Saeed
Published: June 2020

This chapter extends application of a framework proposed by the authors (73, 74) for automated damage detection using strain measurements to study feasibility of using sensors that can measure accelerations, tilts, and displacements. The study utilized three-dimensional (3D) finite element models of double track, riveted, steel truss span, and girder bridge span under routine train loads. The chapter also includes three instrumentation schemes for each bridge span (65) to investigate the applicability of the framework to other bridge systems and sensor networks. Connection damage was simulated by reducing rotational spring stiffness at member ends and various responses were extracted for each damage scenario. The methodology utilizes Supervised Machine Learning to automatically determine damage location (DL) and intensity (DI). Simulated experiments showed that DLs and DIs were detected accurately for both spans with various structural responses and using different instrumentation plans.
New Hybrid Gene Selection-Sample Classification Method in Microarray Data
Authors: Das Chandra , Bose Shilpi , Dutta Sourav , Ghosh Kuntal , Chattopadhyay Samiran
Published: June 2020

The gene expression dataset generated by DNA microarray technology contains expression profiles of huge quantities of genes for very small samples. Among these genes, a very small number of genes are informative for cancer sample identification and classification. Informative genes finding is an essential task of microarray gene expression data analysis. Here, a new hybrid gene selection-sample classification model (NHGSSC) is proposed for selection of relevant genes and classification of cancer samples. The NHGSSC performs two tasks-gene selection and sample classification. For gene selection, a new hybrid single filter and α-depth limited best first search based single wrapper method (SFα-BFSSW) is proposed. From these subsets, highly informative genes are selected by counting frequency of occurrence (FO) of every gene. Then SFα-BFSSW method-based ensemble classifier (SFα-BFSSWEC) is built by combining the classifiers created for the selected gene subsets. Experimental results demonstrate the superiority of the NHGSSC to other existing models.
Principles of Digital Watermarking
Authors: Trivedi Naresh Kumar , Kumar Suresh , Maheshwari Shikha
Published: June 2020

This chapter introduces the benefits of watermark over cryptography and stenography. It provides the digital ownership on a file, but the noise is also attached with the file. Even if somebody copies the file and claims ownership, watermark still provides security. Watermarking is a robust and secured technique compared to other techniques. Implementation cost of this technique is optimized. This chapter also elucidates the attacks on watermarks and solutions to handle these attacks. Authors suggest watermarking will remain unchanged even if the file is compressed.

Published: June 2020

The purpose of this chapter is to have a further understanding of the issue and challenges of visitors in attending the small-scale sport event (SSSE). Although visitors are interested in mega-events, several SSSE is also organized, as SSSE can be a part of the tourism products. Understanding the issues and challenges will enhance SSSE to become one of the popular attractions for local tourism products. The issues that are being faced by the event organizers are insufficient facilities, the age limit of the participant, safety, the event quality, and the suitability of the location. This understanding will enhance the image of the small-scale sports events. Consequently, the organizer of small-scale sports events should better design the events and ensure that it will become an attraction for the enrichment of the local tourism products.

Expenditure Behaviour and Satisfaction in Motor Sport Events
Authors: Pischedda Gianfranco , Marinò Ludovico , Del Chiappa Giacomo
Published: June 2020

This chapter examines the differences in expenditure and satisfaction among first-time and repeat spectators at a motor sports event. A structured questionnaire was developed, and data were collected on site via 318 interviews carried out during the 2019 Federation Internationale de l'Automobile World Rally Championship in Sardinia. Data were analysed by running a series of descriptive analyses, independent t-tests, and regression analyses. The results show that repeaters are more satisfied and spend more when compared to first timers. This study helps to extend the scientific debate related to the growing, and often still inconsistent, comparison of first-timers' and repeat visitors' behaviours by offering insights from a motor sports event, where little research exists so far. Based on the findings, managerial implications are discussed, and suggestions for further research are given.

The purpose of this article is to suggest a better and efficient integrity verification technique for data referred to as cloud audit. The deployment of cloud storage services has significant benefits in the management of data for users. However, this raises many security concerns, and one of them is data integrity. Though public verification techniques serve the purpose they are vulnerable to procrastinating auditors who may not perform verifications on time. In this article, a cloud data auditing system is proposed. The proposed cloud data auditing system integrates Merkle Tree-based Cloud audit and the blockchain-based audit recording system, thus the core idea is to record each verification result into a blockchain as a transaction. Utilizing the time-sensitive nature of blockchain, the verifications are time-stamped after the corresponding transaction is recorded into the blockchain, which enables users to check whether auditors have performed the verifications at the prescribed time. The proposed cloud data auditing system is experimentally validated. The investigations with varied dataset size revealed less time taken, on an average of 0.25 milliseconds with the use of Merkle Tree. Further results reveal consistency of the data integrity checking.

The factors of Cloud computing (CC) adoption among small and medium enterprises (SMEs) have not been identified in the Jordanian context. Therefore, the aim of this study is to examine the factors influencing the adoption of CC in SMEs in Jordan. Through an extensive review of the literature, the research model was constructed based on the TOE framework. In order to validate the research model and test the proposed hypotheses, a quantitative research methodology followed in which a survey questionnaire was utilized to collect the data. Out of the 350 distributed questionnaires, 92 questionnaires were valid for the analysis. The PLS-SEM technique was used for the data analysis. The results approved the influence of six variables on the adoption of CC by manufacturing SMEs in Jordan, namely; compatibility, security, top management support, technological readiness, prior IT experience, and competitive pressure. Only the influence of the perceived benefits has not been supported. The study has theoretical implications and practical implications to SMEs in Jordan.

Despite the increase in the globally connected population, there is still a high percentage of European citizens who do not have basic digital skills. In the era of smart cities, the Digital Divide affects the possibility for citizens to participate in public life through the use of ICT tools. To deal with this issue, the European Union promotes strategies to develop e-government tools, such as digital participatory platforms (DPPs), in order to connect citizens with the public administration. The research proposes a survey of Italian DPPs, investigated through a questionnaire, to bring out which strategies have been adopted in relation to participation, social inclusion and digital illiteracy, transparency of data, processes, and user-friendliness of the platform. With regard to these issues, certain elements of success of the DPPs presented are highlighted.

Published: June 2020

Critical care nurses experience high levels of workplace stress, which can lead to burnout. Many medical centers have begun offering wellness programs to address burnout in their nursing staff; however, most of these programs focus on reducing negative states such as stress, depression, and anxiety. A growing body of evidence highlights the unique, independent role of positive emotion in promoting adaptive coping in the face of stress. This article describes a novel approach for preventing burnout in critical care nurses: an intervention that explicitly aims to increase positive emotion by teaching individuals empirically supported skills. This positive emotion skills intervention has been used successfully in other populations and can be tailored for critical care nurses. Also discussed are recommendations for addressing burnout in intensive care unit nurses at both the individual and organizational levels.
“She's Dead!” – Nursing Simulation Practices: A Discourse Analysis Approach
Authors: Mohammad Abeer
Published: June 2020

Background

The literature on nursing education has revealed a growing wave of interest in the use of simulation sessions to promote undergraduate nurses’ learning experiences. This high prevalence of simulation practices in nursing programs has led to opportunities to research this topic from various angles, including its impact on students’ skill performance, self-efficacy, self-confidence, self-satisfaction, and clinical knowledge acquisition.

Design and methods

Participants in this qualitative study included 54 senior female undergraduates enrolled in a critical care nursing course in Saudi Arabia. Recordings were made of six authentic, acute care simulation sessions. One of these sessions was examined in depth using discourse analysis approaches to gain insights into communication in simulation sessions, examining the way students linguistically managed this critical communication, exhibiting their logical, reflective, decision-making, problem-solving, and collaborative work skills and use of communicative strategies.

Results

The analyses revealed various training and communication issues including the lack of harmony among the team members (e.g., regarding understanding and performing their assigned roles as well as delegating and conducting delegated tasks) and the students’ inability to effectively communicate with the patient as a valuable source of information and to make appropriate and timely clinical decisions regarding patient assessment.

Conclusions

Simulation sessions have been shown to be a promising instructional tool to support nursing education, allowing students to practice in a safe and controlled environment. However, for more effective sessions and to avoid poor simulation sessions, students need to be thoroughly briefed regarding the sessions prior to implementation.

Published: June 2020

Bats emerge from their day roost after dusk and different factors can affect the timing of departure, return, and duration of nocturnal activities. This study provides information on the time of emergence and return of an endemic Malagasy fruit bat, Rousettus madagascariensis, in a cave located in the Réserve Spéciale d’Ankarana, northern Madagascar. Individuals were captured in a narrow passage between the roost and cave exit and capture time for each individual was noted. Variation according to sex, age, and body condition, as well as the influence of season, and the sunset and sunrise time were analyzed. During the dry season, individuals started to emerge at 1913 hours and returned to the cave generally by 0505 hours; the duration of time outside the cave during the dry season was higher in adult females (0952 hours) followed by subadult males (0937 hours), sub-adult females (0931 hours), and adult males (0910 hours). During the wet season, individuals exited at 1926 hours and returned at 0351 hours; as in the dry season, adult females spent more time outside the cave (0833 hours), than sub-adult females (0800 hours), and adult males (0752 hours). The period of emergence varied according to the age and sex classes, and time of predawn return associated with the previous nocturnal activity. The period of return was influenced by season, and age and sex classes. Such information is useful to quantify shifts in bat ecology, especially for endemic species with limited distribution or those playing an important role in ecosystem services.

We aimed to retrospectively determine if initial staging 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) can predict overall survival (OS) in oral cavity squamous cell carcinoma (OCSCC), which is currently a source of ongoing controversy in the literature. Forty-six consecutive patients with nonmetastatic (Stage M0) OCSCC had 18F-FDG PET/CT prior to definitive surgical treatment followed by observation or adjuvant treatment at our institution between 2006 and 2012. The median follow-up time was 18 months (range 0.1–76 months). Univariate and multivariate analysis were used to determine the ability of imaging, pathologic, and demographic factors to predict OS. 18F-FDG PET/CT parameters were standardized uptake value (SUV) maximum and mean, metabolic tumor volume, and total lesional glycolysis (TLG) of primary tumor and regional nodes. Significant predictors of OS in the multivariate analysis were primary tumor SUV mean, nodal TLG, and age. Two-year OS of patients with primary tumor SUV mean below and above the median of 6.26 was 68% and estimated 28%, respectively. Two-year OS of patients with nodal TLG below and above median of 7.9 was 69% and 34%, respectively. Two-year OS of patients younger and older than median age of 57 was 60% and 43%, respectively. Our results suggest that 18F-FDG PET/CT may be a valuable addition to multifactorial models predicting outcome for OCSCC. Thus, continued research aiming to incorporate 18F-FDG PET/CT parameters in risk-stratification algorithms for OCSCC is warranted and should be conducted using more standardized prognostic models driven by a specific clinical question.

Authors: Gupta Nitin , Singh Natasha
Published: June 2020

Oncogenic osteomalacia is a rare condition, with overproduction of fibroblast growth factor 23, leading to hypophosphatemia, phosphaturia. If it is associated with benign mesenchymal tumor, then resection of tumor is curable. Thus, detection and localization of the lesion are of utmost importance. We report a case, where 18F-FDG PET/CT scan was useful in detection of such occult lesion.
