Medical Costs by Disease Stage in Medicare Patients with Metastatic Melanoma

Background: Melanoma is a rare but serious skin cancer that is responsible for >90% of skin cancer-related deaths. This retrospective data analysis quantifies the direct cost of medical care by disease stage at diagnosis for patients with metastatic melanoma. Methods: The Surveillance, Epidemiology, and End Results (SEER)-Medicare database was queried for patients diagnosed between 2004-2009 with stage IIIB/C and stage IV (M1a, M1b, M1c) melanoma. The primary outcome was overall medical utilization and associated costs from diagnosis to death, the end of Medicare enrolment, or 12/31/2010. Results are stratified by disease stage at diagnosis and presented as per-patient per-month (PPPM) costs. Results: Of the 1263 patients meeting the study criteria (mean age: 75 years; 64% male, 92% white, mean duration of follow up: 37.5 months), 66.6% were diagnosed at stage IIIB/C and 33.4% at stage IV. Cost of care increased with disease stage. Total PPPM costs ranged from $1966 for patients diagnosed with stage IIIB to $4585 among patients diagnosed with stage M1c. Outpatient costs accounted 48.9% of total medical costs among stage IIIB patients, and 38.7% of total medical costs for stage M1c patients. Inpatient costs accounted for 37.1% (stage M1b) - 40.9% (stage M1c) of total medical costs. Conclusions: Healthcare costs for treating patients with metastatic melanoma increase by disease stage. The cost of care was more than double among patients with late stage compared to those with early stage. Treatments demonstrating ability to prevent disease progression from early stage to late stage may confer an economic benefit among other clinical advantages.

Adsorption of Lead and Nickel on to Expanded Graphite Decorated with Manganese Oxide Nanoparticles

In this study, expanded graphite (EG) was decorated with manganese oxide nanoparticles (MONPs) by the hydrothermal method, and the newly formed composite (MONPs-EG) was applied as adsorbent for the removal of heavy metals from aqueous solutions. The comparative and competitive adsorption of Pb2+ and Ni2+ (0.01–1.00 mM) on MONPs-EG was investigated. Data from isothermal adsorption of single and binary systems suggested that both Pb2+ and Ni2+ were well described by the Langmuir isotherm, and the maximum adsorption capacities at 298 K were calculated at 0.278 and 0.113 mmol/g for Pb2+ and Ni2+, respectively. In binary systems, a dramatic decrease in adsorption capacity of Ni2+ was observed, while the adsorption capacity of Pb2+ was almost stable, indicating the favorable adsorption of Pb2+ over Ni2+ onto the prepared adsorbent. Kinetics studies of single and binary systems showed that a pseudo-second order model could explain the adsorption processes well. Thermodynamic analysis results demonstrated that the adsorption of these metal ions on the prepared adsorbent is spontaneous and exothermic in nature. The adsorption capacity of MONPs-EG increased significantly in the presence of humic acids. Overall, the results of this study suggest that MONPs-EG can be used effectively as an adsorbent for heavy metals removal from aqueous solutions.
3-D Printed Planar Dielectric Linear-to-Circular Polarization Conversion and Beam-Shaping Lenses Using Coding Polarizer

This article presents a new linear-to-circular polarization conversion coding unit, on which two new kinds of beam-shaping lenses are proposed. First, under periodic boundary conditions, a linear-to-circular polarization conversion coding unit is introduced, which introduces the necessary phase delay by adjusting its geometrical parameters. The phase delay ranges from 0° to 360° and is discretized into 3 bit coding units corresponding to specific delays. Second, by properly arranging the coding units, a high-gain circularly polarized (CP) lens is proposed. The lens achieves linear-to-circular polarization conversion and beam collimation in the transmission mode simultaneously with a planar configuration, which is different from counterparts that place a lens atop of a polarizer. Furthermore, the coding units are used to form Wollaston-prism-like and Rochon-prism-like planar CP beam-shaping lenses, which split the beams with different polarizations into right- and left-handed components. These beams can be controlled independently. Prototypes working at 30 GHz band are designed, fabricated, and measured to verify the idea.
Energy Efficiency Evaluation for Downlink Full-Duplex Nonlinear MU-MIMO-OFDM System With Self-Energy Recycling

Energy-efficient wireless system design has gained considerable attraction owing to the widespread proliferation of wireless devices. The next-generation wireless systems should also be spectrally efficient to sustain the tremendous demand for wireless services. Full-duplex (FD) systems have the potential to double the spectral efficiency (SE) of current half-duplex communication systems. The major challenge in FD systems is the suppression of strong self-interference (SI) imposed by the transmit signal on its receiving antennas. However, SI can also be utilized for recycling of energy by exploiting the radio frequency energy harvesting (RFEH) techniques, which is commonly referred to as self-energy recycling (S-ER). S-ER improves the overall energy efficiency (EE) of the system via recycling a portion of transmitted power. In this article, we evaluate the EE for a downlink FD nonlinear multiuser multi-input–multi-output (MU-MIMO) orthogonal frequency division multiplexing (OFDM) system in the presence of S-ER. The proposed analytical formulation consists of closed-form derivation for EE and SE of the aforementioned system. Furthermore, we have also obtained the outage performance and based on this performance proposed a methodology to allocate the antennas for S-ER while satisfying the quality of service. It has been observed that reserving few antennas for S-ER improves the EE albeit with a slight degradation in SE due to reduced array gain. Consequently, with S-ER, the tradeoff between the SE and EE has been studied for a nonlinear MU-MIMO-OFDM system. Analytical derivation for EE, SE, and outage are followed by simulations for corroborating the proposed analysis.
Emerging trends and research frontiers in spatial multicriteria analysis

ABSTRACT A majority of research on Spatial Multicriteria Analysis (SMCA) has been spatially implicit. Typically, SMCA uses conventional (aspatial) multicriteria methods for analysing and solving spatial problems. This paper examines emerging trends and research frontiers related to the paradigm shift from spatially implicit to spatially explicit multicriteria analysis. The emerging trend in SMCA has been spatially explicit conceptualizations of multicriteria problems focused on multicriteria analysis with geographically varying outcomes and local multicriteria analysis. The research frontiers align with conceptual and structural elements of SMCA and pertain to, among others, theoretical frameworks, problem structuring, model parameter derivation, decision problem contextualization, scale representation, treatment of uncertainties, and the very meaning of decision support. The paper also identifies research directions and challenges associated with developing spatially explicit multicriteria methods and integrating concepts and approaches from two distinct fields: GIS and multicriteria analysis.

Influence of nutritional status on postoperative outcome in patients with colorectal cancer – the emerging role of the microbiome

Abstract Many patients with colorectal cancer are overweight. Even then, nutritional status is a frequently underestimated risk factor for perioperative complications. Enhanced Recovery after Surgery is the goal for perioperative management, and preoperative nutritional risk screening should be a standard. In case of nutritional risk, perioperative nutrition therapy should be started without delay and should follow recent guideline recommendations. The preservation of the microbiome has an emerging role in preventing postoperative anastomotic leakage and septic complications. The time window for recovery after neoadjuvant treatment for rectal cancer may be used for conditioning appropriate-risk patients in a “prehabilitation” program. In order to assess metabolic recovery and the prognosis for long-term survival, C-reactive protein/albumin ratio may be a promising parameter, which has to be validated in the future. This narrative review summarizes recent strategies and guideline recommendations.
The Prevalence of Arterial Hypertension in Sample of Algerian population in Oran city: Inherited Aspect

Background: Arterial Hypertension (AH) is considered as a public health problem due to its high prevalence and difficult control and it’s also described as one of the most important risk factors for cardiovascular diseases. Objectives: This study aimed to determine the prevalence of AH, as well as characteristics related to the presence of its inherited aspect among individuals aging between 24 and 70 years from the urban region of Oran city in Algeria. Methods: Transversal study from January 2010 to January 2011, population- based study, of 620 participants with random sampling. For classification of AH, criteria included blood pressure (BP) ≥ 140/90 mmHg or current use of antihypertensive drugs. Individuals were interviewed with standardized questionnaires previously tested. Results: Arterial Hypertension has a prevalence of 51.6 % in this sample of Algerian population in Oran city, which is composed of 620 individuals. Among hypertensive individuals (n= 320), mean age was 50.6 years, 73.33% was female hypertensive, 31.25% male hypertensive and 62.5% with a family history of Arterial Hypertension, among them: 46% with a maternal family history (FH), 31% with a fraternal FH, 20% with a paternal FH and 4% with a dead fraternal FH, 41% had a family history of cardiovascular disease where those with a stroke family history: 36.58% had a maternal FH, 12.19% with a paternal FH and 7.31% with a fraternal FH, 13.41% with a dead fraternal FH. Those with a family history of myocardial infarction (MI) were: 9.75% with a maternal FH of MI, 14.63% with a paternal FH, 4.86% with a fraternal FH, 2.43% with dead fraternal FH. Another characteristic of this hypertensive population is that 75% had AH associated with Type 2 Diabetes. Conclusions: This study showed that AH represents an important public health problem with its high prevalence within this population. This result points the major role of family history of arterial hypertension and cardiovascular disease; these findings will constitute a data base for genetic studies in order to a better understanding of the gene contribution in the heritability of blood pressure.
(Social) Class Is in Session: Becoming Student-Ready for the Working-Class

WHEN I BEGAN MY FIRST YEAR at the University of California (UC) Davis in the fall of 2003, I became friends with four other working-class students. At the time, I could not clearly articulate that these friends shared a working-class background with me. I just knew that their parents, like my dad, worked blue-collar jobs and had not gone to college. Like me, they navigated many college processes on their own, plodding through the Free Application for Federal Student Aid (FAFSA) and navigating tuition and registration. We spent that initial year adjusting to college life and embracing our newly found independence by riding our bikes to the nearby Rite Aid for $1 ice cream scoops, taking afternoon naps on the ample sunny knolls of campus, and spending too much time on social media. By senior year, only two of us were still enrolled at and would eventually graduate from UC Davis. One friend moved back home and spent the next decade working through courses at a regional comprehensive university. One transferred to a community college. One I lost touch with completely. Looking back, there were warning signs during that first year that my friends were encountering challenges at UC Davis that would eventually push them into alternative educational paths. One experienced early bouts with depression, amplified by the 400 miles between Davis and her hometown, that went unnoticed by university staff. All three were uninvolved on campus beyond going to and coming from class, continuing to feel more connected to home communities than to the campus. While we shared working-class backgrounds, my family provided me with significant financial support to fund my education, preventing me from having to navigate varied aid packages every term. Additionally, I alone was white and came from a suburban background. I did not have to navigate the racial climate and culture shock that my friends, students of color from urban backgrounds, experienced. My experiences at UC Davis eventually led me to a career in higher education, first as a practitioner in student affairs and then in pursuit of a doctorate in Higher Education from the University of Massachusetts Amherst. Consistently, I saw ways that institutions could do more to support workingclass students. In their book Becoming a StudentReady College: A New Culture of Leadership for Student Success, Tia Brown McNair, Susan Albertine, Michelle Asha Cooper, Nicole McDonald, and Thomas Major, Jr. (2016) described the barriers that students encounter as a gap in the responsiveness of college and universities. Reversing traditional narratives that expect students to be college-ready, the authors called on institutions to be student-ready and adapt to the needs of diverse populations. Their suggestions include creating opportunities for shared governance, centering campus-wide learning objectives, and developing partnerships across and beyond campus. For working-class students, student-ready institutions
TRANSPLANTATION OF INSULIN-SECRETING CLUSTERSGENERATED FROM MESENCHYMAL STEM CELLS TO CONTROL INDUCED DIABETES IN RATS

Diabetes mellitus (D.M) is a disease with a high and increasing prevalence. Insulin-producing cells (IPCs) generated from mesenchymal stem cells (MSCs) have shown immense potential for therapy. This study aimed to compare the differentiation potential of 2 kinds of MSCs obtained from human bone marrow (BM), and umbilical cord blood (UCB) into IPCs. In addition, their therapeutic efficiency to control streptozotocin (STZ) – induced diabetic rats was investigated. MSCs were isolated from human BM and UCB, expanded and differentiated to IPCs. The Cells were evaluated by flow cytometry analysis for MSCs markers, RT-PCR for insulin gene expression and ELISA detection of C-peptide release. IPCS were transplanted into the liver of diabetic rats and then evaluated by weekly measurement of the fasting blood glucose (FBG) levels, and detection of in vivo release of C-peptide. This study demonstrated that FBG levels were reduced in diabetic rats transplanted with IPCs, but in rats transplanted with UCB-derived cells were significantly lower than in those transplanted with BM-derived cells. The amount of Cpeptide released from transplanted IPCs derived from BM-MSCs and UCB-MSCs was non-significantly different. The results indicate that UCB- MSCs and BM-MSCs are promising stem cell sources for IPCs that help in the development of a new strategy for treatment of D.M. However, transplantation of IPCs derived from UCB brings better results than BM-derived cells.
The specifics of single-mode laser modules application in optical-electronic complexes based on light scattering

The polarization state of edge-emitting single-mode laser modules radiation and their conditions of using in laser measuring systems of scattered radiation diagnosis are considered. For laser modules from two batches, both the polarization degree of collimated radiation and polarization degree spatial dependence in two orthogonal planes when there is no collimation are measured. It is established the angular dependence of non-collimated radiation polarization degree at different planes is various. We also considered the impact laser diodes degradation on these dependencies. It is shown that while exploitation of single-mode laser diodes in laser systems for scattered radiation characteristics researching it is needed to make control the polarization state of their radiation while service.
Psychological Diversity Climate, Organizational Embeddedness, and Turnover Intentions: A Conservation of Resources Perspective

The hospitality workforce is the most diverse in the United States. Given this fact, a growing body of research has sought to investigate the effects of employee perceptions of their organization’s climate regarding diversity, also known as psychological diversity climate. However, little is still known about whether and how diversity climate perceptions might affect hospitality employees’ intentions to leave their organizations. Adopting a Conservation of Resources Theory perspective, we argue that diversity climate represents an important resource that employees wish to preserve by continuing employment with their organizations, thus increasing employee organizational embeddedness and decreasing turnover intention. Organizational embeddedness captures why employees stay and represents a totality of forces that serve to keep an employee with his or her current organization. These forces are driven by employees’ possession or pursuit of resources derived through employment with their current organization. Drawing on samples of frontline restaurant employees (Study 1) and restaurant managers (Study 2), we found evidence that psychological diversity climate is positively associated with organizational embeddedness. However, the relationship between psychological diversity climate and turnover intentions was mediated only by the sacrifice dimension of organizational embeddedness. Our results point to the importance of developing a positive climate for diversity as a means to retain employees and also shed light on how the dimensions of organizational embeddedness can have differential effects on turnover intentions.
Where Should I Publish to Get Promoted? A Finance Journal Ranking Based on Business School Promotions

Abstract Hiring and promotion committees consider a broad range of journals and the relative importance of journal titles is highly subjective. In this paper, we present a novel approach to objective finance journal ranking by considering the impact of journal publications on career advancement. While the top three journals (Journal of Finance, Journal of Financial Economics, Review of Financial Studies) are significant drivers of promotion success, other journals are nearly as important, particularly for business schools outside of the top tier. In rank order, these are the Journal of Banking and Finance, the Journal of Financial and Quantitative Analysis, the Journal of Corporate Finance, and the Review of Finance.
Estimating and understanding crop yields with explainable deep learning in the Indian Wheat Belt

Forecasting crop yields is becoming increasingly important under the current context in which food security needs to be ensured despite the challenges brought by climate change, an expanding world population accompanied by rising incomes, increasing soil erosion, and decreasing water resources. Temperature, radiation, water availability and other environmental conditions influence crop growth, development, and final grain yield in a complex nonlinear manner. Machine learning (ML) techniques, and deep learning (DL) methods in particular, can account for such nonlinear relations between yield and its covariates. However, they typically lack transparency and interpretability, since the way the predictions are derived is not directly evident. Yet, in the context of yield forecasting, understanding which are the underlying factors behind both a predicted loss or gain is of great relevance. Here, we explore how to benefit from the increased predictive performance of DL methods while maintaining the ability to interpret how the models achieve their results. To do so, we applied a deep neural network to multivariate time series of vegetation and meteorological data to estimate the wheat yield in the Indian Wheat Belt. Then, we visualized and analyzed the features and yield drivers learned by the model with the use of regression activation maps. The DL model outperformed other tested models (ridge regression and random forest) and facilitated the interpretation of variables and processes that lead to yield variability. The learned features were mostly related to the length of the growing season, and temperature and light conditions during this time. For example, our results showed that high yields in 2012 were associated with low temperatures accompanied by sunny conditions during the growing period. The proposed methodology can be used for other crops and regions in order to facilitate application of DL models in agriculture.
