Use of convalescent plasma transfusions could be of great value in the current pandemic of coronavirus disease (COVID-19), given the lack of specific preventative and therapeutic options. This convalescent plasma therapy is of particular interest when a vaccine or specific therapy is not yet available for emerging viruses, such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19. This report summarizes existing literature around convalescent plasma as a therapeutic option for COVID-19. ⋯ The immediate use of convalescent plasma provides prompt availability of a promising treatment while specific vaccines and treatments are evaluated and brought to scale. Further development of improved convalescent plasma, vaccines and other therapeutics depends on quick generation of additional data on pathogenesis and immune response. Additionally, given the lack of information around the natural history of this disease, PRT should be considered to add a layer of safety to protect recipients of convalescent plasma.

Detection and Isolation of SARS-CoV-2 in Serum, Urine, and Stool Specimens of COVID-19 Patients from the Republic of Korea.
Coronavirus Disease-19 (COVID-19) is a respiratory infection characterized by the main symptoms of pneumonia and fever. It is caused by the novel coronavirus severe acute respiratory syndrome Coronavirus-2 (SARS-CoV-2), which is known to spread via respiratory droplets. We aimed to determine the rate and likelihood of SARS-CoV-2 transmission from COVID-19 patients through non-respiratory routes. ⋯ While the virus remained detectable in the respiratory samples of COVID-19 patients for several days after hospitalization, its detection in the serum, urine, and stool samples was intermittent. Since the virus could not be isolated from the SARS-COV-2-positive samples, the risk of viral transmission via stool and urine is expected to be low.

This paper continues a recent study of the spike protein sequence of the COVID-19 virus (SARS-CoV-2). It is also in part an introductory review to relevant computational techniques for tackling viral threats, using COVID-19 as an example. Q-UEL tools for facilitating access to knowledge and bioinformatics tools were again used for efficiency, but the focus in this paper is even more on the virus. ⋯ However compounds like emodin that inhibit SARS entry, apparently by binding ACE2, might also have functions at several different human protein binding sites. The enzyme 11β-hydroxysteroid dehydrogenase type 1 is again argued to be a convenient model pharmacophore perhaps representing an ensemble of targets, and it is noted that it occurs both in lung and alimentary tract. Perhaps it benefits the virus to block an inflammatory response by inhibiting the dehydrogenase, but a fairly complex web involves several possible targets.

Case ReportsPersistence of intestinal SARS-CoV-2 infection in patients with COVID-19 leads to re-admission after pneumonia resolved.
The current reports of COVID-19 focus on the respiratory system, however, intestinal infections caused by SARS-CoV-2 are also worthy of attention. This paper reported persistence of intestinal SARS-CoV-2 infection leads to re-admission after pneumonia resolved in three cases with COVID-19.

[Strategies and recommendations for urolithiasis treatment and follow-up in COVID-19 pandemia.]
The health crisis caused by COVID-19 pandemic has led to a restructuring of urological activity in order not to delay priority situations. An important part to prioritize within Urologyis Urolithiasis. The objective of this article is to establish strategies and recommendations for the treatment and follow-up in COVID-19 pandemic in phases I, II and III, based on available scientific evidence and the consensus of a group of experts in these pathologies. MATERIAL AND METHODS: The document is based on the evidence available in the literature so far on SARSCoV-2 and the experience of the authors in the management of COVID-19 in their institutions. A narrative review of the literature was conducted, and a modified nominal group technique was used due to the extraordinary restrictions of assembly and mobility during the pandemic. RESULTS: Recommendations are made regarding the epidemiological evaluation of patients before surgery ,the management of positive patients, the epidemiological measures for healthcare personnel, the management of renal colic, the type of anesthesia, endourological surgery, shockwave lithotripsy, hospitalization, clinicalt ests, out-patient service and priorities on the surgical waiting list. CONCLUSION: Treatment of Urolithiasis in COVID-19 pandemic calls for prioritization of patients, maximum efficiency in treatments, adequate protection of healthcare personnel, and the implementation of telemedicine as a measure to reduce patient attendance to the hospital.
