BACKGROUND Uveal melanoma (UM) is the most common primary ocular malignancy of adults. A small group of patients was found to express familial predisposition. Moreover, it may be preceded or followed by other malignancies elsewhere in the body. We aim to compare the incidence of UM and other associated cancers and study the factors that may influence each condition. PATIENTS AND METHODS We have collected the data from the Surveillance, Epidemiology and End Results database of nine US cancer registries for UM patients between 1973 and 2015. We calculated the standardised incidence ratios for single primary UM, first primary and second primary UM, and compared the groups for multiple factors. RESULTS A total of 4946 patients were included in the study; 3863 with single primary UM, 646 developed a second primary malignancy following UM, and 437 patients developed second primary UM following a previous primary malignancy. The risk of developing UM increased after leukaemia, melanoma of the skin and prostate. On the other side, the risk of developing melanoma of the skin, thyroid, renal and other eye and orbit malignancies has increased significantly after initial UM. This risk was more evident in the age group between 50 and 70 years old. Cancer-specific survival was significantly higher in UM associated with other malignancies group compared with single primary UM. CONCLUSION Our study showed a different behaviour of the UM when associated with other tumours that exceed the known spectrum of hereditary UM. Further studies are required to dissect the genetic background of this behaviour.

BACKGROUND Marital status influences the presentation and outcome of various cancers. We explored the relationship between marital status and survival of uveal melanoma (UM) and factors influencing this relationship. METHODS We conducted a retrospective cohort study on patients diagnosed with UM and registered in the Surveillance Epidemiology and End Results program between 1973 and 2017. Cox regression model was conducted to calculate the hazard ratio of overall and cancer-specific survival rate and delineate the effect of each confounder. RESULTS The study involved 10,557 patients with a male-to-female ratio of 1:1.1. Most of the diagnosed patients were aged between 40 and 79 years (81%). Married patients (62%) represented the majority, followed by singles (12%), widowed (11%), and then divorced patients (7%). Single patients were the youngest group (mean age of 59.3 years) while widowed patients were the oldest (mean age of 75.8 years). In the Cox regression model for overall survival, married and single patients exhibited the best overall survival (no significant difference in between them), both surpassing divorced and widowed patients. Married patients were at a significantly lower risk to die from UM than divorced patients. Female patients and younger age groups showed the best overall and cancer-specific survival. CONCLUSION Maintained marriages improved the survival of UM patients. Widowed and divorced patients should be included in specially designed support programs during their cancer management.

(1) Background: Ultraviolet-visible (UV-Vis) spectroscopy is a common analytical tool to detect chromophore in compounds by monitoring absorbance spectral wavelengths. Further, it could provide spectral information about complex conjugated systems in mixtures aided by chemometric tools to visualize large UV-Vis datasets as typical in food samples. This review provides novel insight on UV-Vis applications in the last 20 years, as an advanced analytical tool in the quality control of food and dietary supplements, as well as several other applications, including chemotaxonomy, authentication, fingerprinting, and stability studies. (2) Conclusions: A critical assessment of the value of UV application and its novel trends in the quality control (QC) of nutraceuticals reveals the advantages and limitations, focusing on areas where future advancements are in need. Although simple, UV and its novel trends present potential analytical tools with an acceptable error for QC applications from a non-targeted perspective compared to other expensive spectral tools.

Elassal, M. M., Utilizing the Theory of Constraints in Supply Chain Network Design, , Giza, Cairo University, 2014. Abstract

Over the past decades, companies have become more and more concerned with maximizing company profits as well as maximizing their customer service level by efficiently managing supply chains. This thesis focuses on three major supply chain decisions that are highly related to supply chain profit, namely facility location, safety stock, and lot sizing. The first decision is strategic in nature, as a part of the supply chain network design, while the other two can be classified as operational decisions. The current study attempts to deploy concepts borrowed from the Theory of Constraints (TOC) to maximize the overall throughput of the supply chain rather than maximizing the throughput of every process separately. By utilizing this concept, supply chain network design decisions should be made to minimize the amount of inventory at each region in order to reach the global optimization.
This thesis is intended to formulate, solve, and implement a mathematical model that incorporates the concepts of TOC into multi-echelon supply chain network design under demand uncertainty to determine the optimal location of facilities and the optimal lot size. The objective is to minimize the total cost across the supply chain network as well as to minimize the total inventory capacity at each facility. For that purpose, the researcher follows an incremental methodology in which a series of mathematical models are developed and solution algorithms are proposed and tested leading to a final comprehensive model. The first model focused on locating a new distribution center under demand uncertainty. It is, then, extended in the second model to consider the location of a new distribution center with varying inventory capacity. Another model is then applied to tackle the joint economic lot sizing problem (JELS) under demand uncertainty. The fourth model further integrates the facility location problem with the joint economic lot sizing problem under demand uncertainty. Finally, the fifth model utilizes the TOC in integrated facility location and joint economic lot sizing problems.
In order to solve these models, several computational intelligence optimization techniques are proposed, implemented, and compared: particle swarm optimization (PSO), gravitational system search (GSA), cuckoo search (CS), charged system search (CSS), non-dominated sorting charged system search (NSCSS), non-dominated sorting particle swarm (NSPSO) algorithm, and non-dominated genetic-II (NSGA-II).
Given the constrained nature of the problem, the thesis proposes and compares four methods (i.e. naive, penalty, penalty with feasibility rules, and heuristic) for handling problem constraints; moreover, it proposes and testes a mixed integer procedure (MI) for converting continuous stochastic algorithms into mixed integer stochastic algorithms.
The numerical analysis of results is accordingly presented, including comparisons with models established in the literature. In general, results show that applying the TOC reduces the total cost of the whole supply chain by about 50%. Results also demonstrate that solving the multi-objective problems by using multi-objective stochastic algorithms is better than solving them by using single objective stochastic algorithms, thereby reducing the total cost more than 80% and reducing the total inventory more than 18%; the best algorithm is, thus, the NSPSO with 99.71% of its final solutions ranked on the first front. Additionally, using varying inventory reduces the total inventory amount by about 20%. The suggested penalty with feasibility rules constraint handling method is considered better than the penalty or feasibility rules alone. The findings also assert that the CSS algorithm is the best algorithm for solving JELS problems.
