Background Since the COVID-19 pandemic began, there have been concerns related to preparedness of healthcare workers (HCWs). This study aimed describe level awareness and hospital HCWs at time first wave. Methods multinational, multicenter, cross-sectional survey was conducted among from February May 2020. We used a hierarchical logistic regression multivariate analysis adjust influence variables based on preparedness. then association rule mining identify relationships between HCW...
Vaccine hesitancy is considered as one of the greatest challenges to control ongoing coronavirus disease 2019 (COVID-19) pandemic. A related challenge unwillingness general public pay for vaccination. The objective this study was determine willingness-to-pay (WTP) COVID-19 vaccine among individuals from ten low- middle-income countries (LMICs) in Asia, Africa, and South America. Data were collected using an online questionnaire distributed during February - May 2021 LMICs (Bangladesh,...
Abstract Introduction Retinoblastoma (RB) is the most common primary intraocular cancer of childhood. Over last few decades, a variety techniques and treatment modalities emerged that improved survival ocular salvage rate patients with RB. We investigated relative trends RB from 2000 to 2018 by using Surveillance, Epidemiology, End Results (SEER) database. Design Retrospective database review. Methods extracted data SEER 18 2018. All clinically diagnosed during study period were included....

Comprehensive analysis of mortality and causes death (COD) in cancers was importance to conduct intervention strategies.The current study aimed investigate the rate COD among cancers, explore disparities between age.Initially, cancer patients diagnosed 2010 2019 from surveillance, epidemiology, end results (SEER) database were extracted.Then, frequencies percentage deaths, different age groups calculated.Meanwhile, distribution across tumor types illustrated while standardized ratios (SMR)...
We discuss the design and development of highly cost effective, semi-autonomous reconnaissance Unmanned Aerial Vehicle (UAV) for safe flights in close environments, with real time video feedback. The is based on modifications/up gradations, (predicated results several small experiments), a very low cost, sized - toy helicopter, simple non-linear control system designed intelligent UAV features. developed helicopter has been successfully test-flown at higher altitudes, heavier payload, longer...

Pheochromocytoma (PHEO) and paraganglioma (PGL) are relatively rare neuroendocrine tumors. The factors affecting patients with early death remain poorly defined. We aimed to study the demographic clinicopathologic pattern develop validate a prediction model for PHEO/PGL death.Data of 800 participants were collected from Surveillance Epidemiology End Results (SEER) database as construction cohort, while data 340 selected validation cohort. Risk considered included year diagnosis, age at...
