Multiplexed detection of SARS-CoV-2 and other respiratory infections in high throughput by SARSeq.

The COVID-19 pandemic has demonstrated the need for massively-parallel, cost-effective tests monitoring viral spread. Here we present SARSeq, saliva analysis by RNA sequencing, a method to detect SARS-CoV-2 and other respiratory viruses on tens of thousands of samples in parallel. SARSeq relies on next generation sequencing of multiple amplicons generated in a multiplexed RT-PCR reaction. Two-dimensional, unique dual indexing, using four indices per sample, enables unambiguous and scalable assignment of reads to individual samples. We calibrate SARSeq on SARS-CoV-2 synthetic RNA, virions, and hundreds of human samples of various types. Robustness and sensitivity were virtually identical to quantitative RT-PCR. Double-blinded benchmarking to gold standard quantitative-RT-PCR performed by human diagnostics laboratories confirms this high sensitivity. SARSeq can be used to detect Influenza A and B viruses and human rhinovirus in parallel, and can be expanded for detection of other pathogens. Thus, SARSeq is ideally suited for differential diagnostic of infections during a pandemic.

[Antiepileptic agents in the treatment of symptomatic epileptic seizures during and after cerebrovascular insult (CVI)]. / Antiepileptici u tretmanu simptomatskih epileptickih napada u toku i nakon CVI.

The epileptic seizures occur as the consequence of THE cerebrovascular insult. The morphologic changes at the brain after cerebrovascular insult are responsible for its occurrence. The pathophysioloogic basis of the late epileptic manifestations (after the second week after CVI) are the epyleptic activities of the morphological brain changes which behave according to the type of the "epileptogene focus". The epileptic seizures which occur during CVI are the result of the moleculary changes which occur in ischemia as the primary, and in haemohagia as secondary ones. The aim of our paper is to see the therapeutic aspects of the early and late epileptic seizures during and after cerebrovascular insult. In the course of the retrospective processed treatment of the patients at our clinic, and in the ten years period (01.01.1989-31.12.1998), we treated 7001 patients with the various types and subtypes of CVI. The incidence of the epileptic seizure moved from 0.65% (1994) till 3.14% (1998). In our sample we had 111 patients with late epileptic seizures, and 56 patients with early epileptic seizures. The early epileptic seizures in most cases were treated by Diazemap intravenously, while in the group of the patients with late seizures, most frequently we applied Fenobarbiton, and later diazepam intravenously. After the seizures and admission at the Clinic and in the future treatment most often we recommended and gave diazemap, phenobarbiton and karabo zepine. The therapeutic effects of the applied therapy were statistically significant. It is significant that there were more patients of the applied therapy statistically significantly. It is significant that there were more patients had no later seizures or of whose the seizures were more rarely (Hi2 = 14.209, n = 2, p < 0.01). On the basis of our research we can conclude that the therapeutic principle of the symptomatic epileptic seizures during and after cerebrovascular insult is the principle of the MONOTHERAPY. On the basis of our material we came to the conclusion that kabazepin optimally antiepileptic for this group of symptomatic epileptic seizures.

[Abuse of psychoactive substances by adolescents in rural and urban environments]. / Zloupotreba psihoaktivnih supstanci kod adolescenata u ruralnoj i urbanoj sredini.

It is well known that drug abuse is common in early adolescence with almost the same epidemiological characteristics in economical developed and undeveloped countries. Aim of this study is to compare drug abuse among adolescents in the urban and rural areas. Research covers 600 adolescents equal gender and age distribution. Distribution of participants regarding to the rural and urban type of areas, was equal, as well. It was used Q 2000 questionnaires, which was comprehensive tool for all aspects of adolescents life. Results shows that drug abuse is much more common in urban areas (alcohol 62.4%; and cannabis 70.0%; in rural areas alcohol 37.6%; and cannabis 30.0%). Regarding to age, drug abuse is the most common among adolescents aged 15-17. Alcohol is much more related to boys, but regarding to cannabis there is almost no differences.
