The D614G mutation in the SARS-CoV-2 spike protein reduces S1 shedding and increases infectivity
https://www.scripps.edu/_files/pdfs/news-and-events/The D614G mutation in the SARS-CoV-2 spike protein reduces S1.pdf

SARS coronavirus 2 (SARS-CoV-2) isolates encoding a D614G mutation in the viral spike (S) protein predominate over time in locales where it is found, implying that this change enhances viral transmission. We therefore compared the functional properties of the S proteins with aspartic acid (SD614) and glycine (SG614) at residue 614. We observed that retroviruses pseudotyped with SG614 infect...

https://dailynews.ascopubs.org/do/10.1200/ADN.20.200232/full/

Jul 2nd, 2020 - The phase III HERO trial (Abstract 5602) investigated the results of relugolix, an orally bioavailable GnRH receptor antagonist, for patients with advanced prostate cancer. Treatment with relugolix resulted in superiority over leuprolide in achieving sustained testosterone suppression. Additionally, treatment was associated with faster testosterone recovery and decreased major adverse cardiovas...

Can a toilet promote virus transmission? From a fluid dynamics perspective
https://aip.scitation.org/doi/10.1063/5.0013318

Currently, a novel coronavirus named “SARS-CoV-2” is spreading rapidly across the world, causing a public health crisis, economic losses, and panic. Fecal–oral transmission is a common transmission route for many viruses, including SARS-CoV-2. Blocking the path of fecal–oral transmission, which occurs commonly in toilet usage, is of fundamental importance in suppressing the spread of viruses. H...

https://www.thelancet.com/pdfs/journals/langas/PIIS2468-1253(20)30083-2.pdf

We present severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) real-time RT-PCR results of all respiratory and faecal samples from patients with coronavirus disease 2019 (COVID-19) at the Fifth Affiliated Hospital of Sun Yat-sen University, Zhuhai, China, throughout the course of their illness and obligated quarantine period.

Effects of temperature and humidity on the daily new cases and new deaths of COVID-19 in 166 countries
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7187824/

The coronavirus disease 2019 (COVID-19) pandemic is the defining global health crisis of our time and the greatest challenge facing the world. Meteorological parameters are reportedly crucial factors affecting respiratory infectious disease epidemics; however, the effect of meteorological parameters on COVID-19 remains controversial. This study investigated the effects of temperature and relati...

Early neurological manifestations of hospitalized COVID-19 patients
https://link.springer.com/article/10.1007/s10072-020-04525-z

Neurological manifestations can occur during coronavirus disease 19 (COVID-19). Several pathogenic mechanisms have been hypothesized, without conclusive results. In this study, we evaluated the most frequent neurological symptoms in a cohort of hospitalized COVID-19 patients, and also investigated the possible relationship between plasmatic inflammatory indices and olfactory disorders (ODs) and...

Investigation into SARS-CoV‑2 Resistance of Compounds in Garlic Essential Oil
https://pubs.acs.org/doi/pdf/10.1021/acsomega.0c00772

Eighteen active substances, including 17 organosulfur compounds found in garlic essential oil (T), were identified by GC−MS analysis. For the first time, using the molecular docking technique, we report the inhibitory effect of the considered compounds on the host receptor angiotensin-converting enzyme 2 (ACE2) protein in the human body that leads to a crucial foundation about coronavirus ...

https://dailynews.ascopubs.org/do/10.1200/ADN.20.200217/full/

Jun 23rd, 2020 - A switch maintenance therapy approach using the immune checkpoint inhibitor avelumab in patients with advanced urothelial carcinoma (UC) who had not progressed after induction platinum-based chemotherapy offered significantly improved survival outcomes, according to results of the JAVELIN Bladder 100 trial (Abstract LBA1). The study, which was the first UC study ever presented during an ASCO An...

Will DFS Benefit Translate Into Survival Benefit in ADAURA?
https://dailynews.ascopubs.org/do/10.1200/ADN.20.200221/full/

Jun 23rd, 2020 - The report on ADAURA during the ASCO20 Virtual Scientific Program Plenary Session surprised many, first because the initial data readout for the phase III trial was not planned until 2022 and second because of the strength of the disclosed data (Abstract LBA5). Early unblinding of the results revealed an 83% reduction in the risk of disease recurrence or death with use of adjuvant osimertinib c...

Clinical Implications of First-Line Pembro for MSI-High mCRC
https://dailynews.ascopubs.org/do/10.1200/ADN.20.200220/full/

Jun 23rd, 2020 - Long-awaited results from the randomized, phase III KEYNOTE-177 trial provide strong support for using single-agent pembrolizumab instead of a chemotherapy-based regimen in patients newly diagnosed with metastatic colorectal cancer (mCRC) featuring high-level microsatellite instability (MSI-H) or deficient mismatch repair (dMMR; Abstract LBA4).

KRd, VRd Equivalency in Multiple Myeloma ‘Reassuring’ to Hematologists
https://dailynews.ascopubs.org/do/10.1200/ADN.20.200219/full/

Jun 23rd, 2020 - Awaited results of the ENDURANCE trial showed equivalency between a regimen of carfilzomib plus lenalidomide and dexamethasone (KRd) and bortezomib, lenalidomide, and dexamethasone (VRd) as an initial therapy for patients with standard- or intermediate-risk multiple myeloma (Abstract LBA3). KRd failed to improve progression-free survival compared with VRd, according to data presented by Shaji K...

Flow-metabolism dissociation in the pathogenesis of levodopa-induced dyskinesia
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5033758/

Levodopa-induced dyskinesia (LID) is the most common, disruptive complication of Parkinson’s disease (PD) pharmacotherapy, yet despite decades of research, the changes in regional brain function underlying LID remain largely unknown. We previously found that the cerebral vasomotor and metabolic responses to levodopa are dissociated in PD subjects. Nonetheless, it is unclear whether levodopa-med...

https://www.nature.com/articles/s41586-020-2521-4_reference.pdf

COVID-19 has rapidly afected mortality worldwide1 . There is unprecedented urgency to understand who is most at risk of severe outcomes, requiring new approaches for timely analysis of large datasets. Working on behalf of NHS England, here we created OpenSAFELY: a secure health analytics platform covering 40% of all patients in England, holding patient data within the existing data centre ...

Expression of the COVID‐19 receptor ACE2 in the human conjunctiva
https://onlinelibrary.wiley.com/doi/full/10.1002/jmv.25981

SARS‐CoV‐2 is assumed to use angiotensin‐converting enzyme 2 (ACE2 ) and other auxiliary proteins for cell entry. Recent studies have described conjunctival congestion in 0.8% of patients with laboratory‐confirmed severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2), and there has been speculation that SARS‐CoV‐2 can be transmitted through the conjunctiva. However, it is currently uncle...

COVID-19 receptor ACE2 is expressed in human conjunctival tissue, expecially in diseased conjunctival
https://www.medrxiv.org/content/10.1101/2020.05.21.20109652v1.full.pdf

COVID-19 virus has currently caused major outbreaks worldwide. ACE2 is a major cellular-entry receptor for the COVID-19 virus. Although ACE2 is known to be expressed in many organs, whether it is expressed by the conjunctival tissue is largely unknown. Human conjunctival tissues from 68 subjects were obtained, which included 10 subjects with conjunctival nevi, 20 subjects with conjunctiviti...

The SARS-CoV-2 is the causative agent for COVID-19 pneumonia. Little is known about the 60 kinetics, tissue distribution, cross-reactivity and neutralization antibody response in COVID61 19 patients. Two groups of RT-PCR confirmed COVID-19 patients were enrolled in this study, 62 including 12 severe patients in ICUs who needed mechanical ventilation and 11 mild patients 63 in isolation wards...

Is cannabidiol the ideal drug to treat non-motor Parkinson’s disease symptoms?
https://link.springer.com/article/10.1007/s00406-019-00982-6
European Archives of Psychiatry and Clinical Neuroscience;

Parkinson’s disease (PD) is a chronic neurodegenerative disorder characterized by motor symptoms such as bradykinesia, rest tremor, postural disturbances, and rigidity. PD is also characterized by non-motor symptoms such as sleep disturbances, cognitive deficits, and psychiatric disorders such as psychosis, depression, and anxiety. The pharmacological treatment for these symptoms is limited in ...
