The SARS-CoV-2 virus continues to overwhelm health care systems impairing human to human social and economic interactions. Invasion or damage to the male reproductive system is one of the documented outcomes of viral infection. Existing studies have reported that SARS-CoV-2 may contribute to this loss in relation to inflammatory responses and the formation of cytokine storms in COVID-19 patients. Although direct infection of the testes and entry of SARS-CoV-2 into semen as well as subsequent consequences on the male reproductive system need to be studied more systematically, warnings from two organising ASRM and SART for prospective parents when infected with SARS-CoV-2 should be considered. In the context of an increasingly complex pandemic, this review provides preliminary examples of the potential impact of COVID-19 on male reproductive health and guidance for prospective parents currently infected with or recovering from SARS-CoV-2.
The automatic number-plate recognition (ANPR) has become more important nowadays, especially for security management, parking management and law enforcement. There are many ANPR systems introduced but almost of them worked under restricted conditions, such as fixed location of ANPR cameras, processing speed and hardware resources. In this paper, we build the Mobile International Number Plate Recognition (MINPR) system which is exploited and implemented on the Android mobile phone platform to solve these problems. The MINPR includes three main steps: using AdaBoots classification with Haar-like features to locate the area which contains the number plate, applying morphology method to separate characters within the number plate, and using neural network for characters recognition.
A cross-sectional study was conducted on 205 pediatric patients, including 150 post-COVID-19 patients and 55 noninfected patients. The study identified 10 common respiratory symptoms in post-COVID-19 patients, with significant differences in clinical symptoms between the 2 groups. Post-COVID-19 pediatric patients had a lower lymphocyte count and a higher rate of pneumonia diagnosis, which can persist for up to 16 weeks after discharge. The study’s findings can help monitor and manage the clinical burden of post-COVID-19 symptoms in the pediatric population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
