Numerous researches on content-based video indexing and retrieval besides video search engines are tied to a large-scaled video dataset. Unfortunately, reduction in open-sourced datasets resulted in complications for novel approaches exploration. Although, video datasets that index video files located on public video streaming services have other purposes, such as annotation, learning, classification, and other computer vision areas, with little interest in indexing public video links for purpose of searching and retrieval. This paper introduces a novel large-scaled dataset based on YouTube video links to evaluate the proposed content-based video search engine, gathered 1088 videos, that represent more than 65 hours of video, 11,000 video shots, and 66,000 unmarked and marked keyframes, 80 different object names used for marking. Moreover, a state-of-the-art features vector, and combinational-based matching, beneficial to the accuracy, speed, and precision of the video retrieval process. Any video record in the dataset is represented by three features: temporal combination vector, object combination vector with shot annotations, and 6 keyframes, sideways with other metadata. Video classification for the dataset was also imposed to expand the efficiency of retrieval of video-based queries. A two-phased approach has been used based on object and event classification, storing video records in aggregations related to feature vectors extracted. While object aggregation stores video records with the maximal occurrence of extracted object/concept from all shots, event aggregation classify based on groups according to the number of shots per video. This study indexed 58 out of 80 different object/concept categories, each has 9 shot number groups.

Purpose/Objective(s): Definitive chemoradiation is the standard of care for anal squamous cell carcinoma (SCC), whose incidence is increasing and primarily affects two subgroups: older women and individuals with HIV. The Patient Protection and Affordable Care Act (ACA) was enacted in 2010, with provisions for Medicaid expansion implemented for most participating states in 2014. Given that younger non-Medicare eligible anal SCC patients tend to include those from traditionally medically disadvantaged subgroups, we sought to assess whether ACA expansion was associated with higher rates of receipt of chemoradiation. Materials/Methods: The National Cancer Database was used to identify patients aged 40 and older diagnosed with Stage I-III anal SCC between 2011-2016. Patients younger than 40 were excluded due to lack of information on Medicaid expansion status. Multivariable logistic regression defined adjusted odds ratios (AORs) of receipt of chemotherapy and radiation to at least 36 Gy with Medicaid expansion status (yes vs. no) as the primary independent variable of interest. Difference in difference (DID) estimates were calculated by Medicaid expansion status. Results: Among 14,546 patients, 8,959 (61.6%) resided in Medicaid expansion states and 12,228 (84.1%) received definitive chemoradiation. Prior to Medicaid expansion, 83.7% and 82.0% of patients in expansion and non-expansion states received definitive chemoradiation, respectively. After Medicaid expansion, there was an increase in receipt of definitive chemoradiation in both expansion (84.9%) and non-expansion (84.9%) states (DID-1.6% [95% CI,-4.1%-0.8%]). In states with Medicaid expansion, the percentage of patients with Medicaid insurance increased from 10.1% to 12.9%, which was greater than in non-expansion states (7.8% to 7.7%, DID 2.8% [95% CI, 0.9%-4.8%]), and the absolute rates of uninsured patients decreased from 4.7% to 1.3% in expansion states, as compared to 10.0% to 6.6% in non-expansion states. On multivariable analysis, female sex, treatment following Medicaid expansion, white race, younger age, lower comorbidity status, and treatment at an integrated network cancer program were associated with greater odds of receipt of definitive chemoradiation (p0.001 for all). Conclusion: Approximately 85% of patients with Stage I-III anal SCC received definitive chemoradiation, without large absolute increases after Medicaid expansion, despite lower rates of no insurance. Disparities in receipt of chemoradiation were observed for several sociodemographic characteristics. Given that non-metastatic anal SCC is a highly curable malignancy, efforts are needed to define barriers to care including in patients with insurance, such as inadequate coverage (underinsurance) or issues with accessibility and completion of guideline-concordant care.

Background: Many studies were published to describe the clinical characteristics of COVID-19, however there is still lack of knowledge and it’s time to take stock of the war against coronavirus disease 2019 (COVID-19) pandemic before we hit another million in a matter of days. Simply Identifying COVID-19 features will help in mapping the disease and guiding pandemic management. A retrospective review, retrospective study was initiated in SKMC to describe the demographic data, clinical characteristics, and outcomes of COVID-19 cases who were hospitalized during that period.Methods: Confirmed positive COVID-19 sample patients from April 1st 2020 to May 31st 2020 in Sheikh Khalifa Medical City. Clinical characteristics, Demographic data, incubation periods, laboratory findings, and patient outcomes data retrieved from 336 cases in the electronic medical chart (SALAMTAK).Results: The median age was 44 years and 83.9% (n = 282) of the patients were men. The patients with diabetes mellitus being the most common risk factor (25.0%), followed by hypertension (22.9%) and Age ≥60 were (13.4%). Total 36 patients (10.7%) were asymptomatic. The most common symptoms were upper respiratory tract symptoms, manifested as dry cough (70.2%), and followed by fever (54.2%), shortness of breath (43.5%), headache (25.9%) and sore throat (25.3%). Less common symptoms were diarrhea (16.7%) chest pain (14.6%). The maximum length of stay is 32 days. The minimum length of stay in [ICU/HDU] was 1 day and the maximum was 21 days.Conclusion: In this retrospective study, fever and cough were common symptoms. Special attention should be given to patients with risk factors especially patients with one risk factor such as diabetic patients, patients with hypertension and older patients over 60 years as they are the most highly prevalent in this case series. Disease was affecting males and D-dimer was significantly elevated in deceased patients.
