Super-spreading events and contribution to transmission of MERS, SARS, and SARS-CoV-2 (COVID-19)
https://www.journalofhospitalinfection.com/article/S0195-6701(20)30177-8/fulltext

There is no clear definition for the term ‘super-spreader’ or ‘super-spreading event’. The World Health Organization refers to a super-spreader as a patient (or an event) that may transmit infection to a larger number of individuals than is usual by one individual (or event). In the severe acute respiratory syndrome (SARS) situation, a super-spreading event was defined as the transmission of SA...

We are actively monitoring for any firms marketing products with fraudulent COVID-19 prevention and treatment claims. The FDA is exercising its authority to protect consumers from firms selling un...

Colchicine as a possible therapeutic option in COVID-19 infection
https://link.springer.com/article/10.1007/s10067-020-05247-5

In contrast, we consider that colchicine can be a good therapeutic option because of several effects in the immunology system involved in SARS-CoV-2 infection and in the acute respiratory distress syndrome (ARDS). Colchicine has effects on the chemotaxis of inflammatory cells such as neutrophils and monocytes and on the intracellular transportation of vesicles such as endosomes and exosomes.

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...

Neurologic Features in Severe SARS-CoV-2 Infection
https://www.nejm.org/doi/full/10.1056/NEJMc2008597

We report the neurologic features in an observational series of 58 of 64 consecutive patients admitted to the hospital because of acute respiratory distress syndrome (ARDS) due to Covid-19. The patients received similar evaluations by intensivists in two intensive care units (ICUs) in Strasbourg, France, between March 3 and April 3, 2020.

https://www.e-jmd.org/upload/jmd-19082.pdf
Journal of Movement Disorders;

We recruited 228 drug-naïve PD patients who were followed for a mean of 6 years. Patients underwent the Cross-Cultural Smell Identification Test (CCSIT), a neuropsychological test, and N-(3-[18F]fluoropropyl)-2β-carbomethoxy-3β-(4-iodophenyl) nortropane positron emission tomography within 6 months of the baseline evaluation. Olfactory dysfunction was categorized as normosmia (CCSIT score ≥ 9)...

Blood Flow and Glucose Metabolism Dissociation in the Putamen Is Predictive of Levodopa Induced Dyskinesia in Parkinson's Disease Patients
https://www.frontiersin.org/articles/10.3389/fneur.2019.01217/full
Frontiers in Neurology;

Nov 20th, 2019 - The forefront treatment of Parkinson's disease (PD) is Levodopa. When patients are treated with Levodopa cerebral blood flow is increased while cerebral metabolic rate is decreased in key subcortical regions including the putamen. This phenomenon is especially pronounced in patients with Levodopa-induced dyskinesia (LID).

Brief recommendations on the management of adult patients with familial hypercholesterolemia during the COVID-19 pandemic
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7204727/

Individuals with Familial Hypercholesterolaemia (FH) are at very high risk of cardiovascular disease, which is associated with poor outcomes from coronavirus infections. COVID-19 puts strain on healthcare systems and may impair access to routine FH services. On behalf of the International Lipid Expert Panel (ILEP) and the European FH Patient Network (FH Europe), we present brief recommendations...

Lungs from patients with coronavirus disease 2019 (COVID-19) have shown typical signs of acute respiratory distress syndrome (ARDS), formation of hyaline membrane mainly composed of fibrin and ‘ground-glass’ opacity. Previously, we showed plasminogen itself is a key regulator in fibrin degradation, wound healing and infection.

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/journals/lanres/article/PIIS2213-2600(19)30417-5/fulltext

There is no proven specific pharmacological treatment for patients with the acute respiratory distress syndrome (ARDS). The efficacy of corticosteroids in ARDS remains controversial. We aimed to assess the effects of dexamethasone in ARDS, which might change pulmonary and systemic inflammation and result in a decrease in duration of mechanical ventilation and mortality.

Heparin therapy improving hypoxia in COVID-19 patients: a case series
https://www.medrxiv.org/content/medrxiv/early/2020/04/30/2020.04.15.20067017.full.pdf

Elevated D-dimer is a predictor of severity and mortality in COVID-19 patients and heparin use during in-hospital stay has been associated with decreased mortality. COVID19 patient autopsies have revealed thrombi in the microvasculature, suggesting intravascular coagulation as a prominent feature of organ failure in these patients. Interestingly, in COVID19, pulmonary compliance is preserved ...

https://www.sciencedirect.com/science/article/pii/S2093791120302961

Coronavirus disease 2019 (Covid-19) poses an important occupational health risk to health workers (HWs) that has attracted global scrutiny. To date, several thousand HWs globally have been reported as infected with the severe acute respiratory syndrome coronavirus 2 virus that causes the disease. It is therefore a public health priority for policymakers to understand risk factors for this vulne...

Surgical Treatment of Levodopa-induced Dyskinesia in Parkinson's Disease
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5586111/

The treatment of motor manifestations of Parkinson's disease (PD) is essentially a trade-off between adequate relief of motor symptoms and prevention and control of motor complications, particularly levodopa-induced dyskinesia (LID). Progression of PD is paralleled by a progressive difficulty in achieving the balance. Functional neurosurgical procedures provide sustained relief of LID in carefu...

Cerebellar Connectivity in Parkinson's Disease With Levodopa-Induced Dyskinesia
https://pubmed.ncbi.nlm.nih.gov/31643140/

The precise pathogenesis or neural correlates underlying levodopa‐induced dyskinesia (LID) remains poorly understood. There is growing evidence of the involvement of the cerebellum in Parkinson's disease (PD). The present study evaluated the role of motor cerebellar connectivity in determining vulnerability to LID.

Seasonality of Respiratory Viral Infections
https://www.annualreviews.org/doi/pdf/10.1146/annurev-virology-012420-022445

The seasonal cycle of respiratory viral diseases has been widely recognized for thousands of years, as annual epidemics of the common cold and influenza disease hit the human population like clockwork in the winter season in temperate regions. Moreover, epidemics caused by viruses such as severe acute respiratory syndrome coronavirus (SARS-CoV) and the newly emerging SARS-CoV-2 occur during ...

Dietary health and CVD: implications for dietary policy in England
https://www.cambridge.org/core/services/aop-cambridge-core/content/view/38A3A8EB94B78EA647B80DACEFCA6710/S0029665119000600a.pdf/dietary_health_and_cvd_implications_for_dietary_policy_in_england.pdf
Proceedings of the Nutrition Society;

CVD is a major burden on the health system in the UK. On average, diets are not aligned with current dietary recommendations, including those for salt, saturated fat, fibre, fruit and vegetables. Obesity prevalence is high and the majority of the population is consuming more energy than required. Addressing these issues would reduce the burden of CVD and help reduce inequalities in health. Ther...
