Aspirin Does Not Improve Survival In Covid-19 Patients: UK Study
▫️Aspirin Does Not Improve The Chances of Survival In Severely ill Covid-19 Patients, Early Results from One of Britain's Biggest Trials Studying The Commonly Used Painkiller And Blood Thinner Showed on Tuesday.
▫️The Scientists Behind The Trial, Which Is Looking Into A Range of Potential Treatments For Covid-19, Evaluated Aspirin's Effects on Nearly 15,000 Hospitalized Patients Infected With The Novel Coronavirus.
- Since The Drug Helps Reduce Blood Clots In Other Diseases, It Was Tested In Covid-19 Patients Who Are At A Higher Risk of Clotting Issues.
▫️The Trial, Run by The University of Oxford, Is Also Looking At The Effectiveness of Several Other Treatments, And Was The First To Show That The Widely Available Steroid Dexamethasone, Could Save Lives of People Severely ill With Covid-19.
▫️The Aspirin Study Did Not Show Any Significant Change To The Risk of Patients Progressing To Invasive Mechanical Ventilation. For Every 1,000 Patients Treated With The Medicine, About Six More Patients Experienced A Major Bleeding Event And About Six Fewer Experienced A Clotting Event, Oxford Said.

UK Study Finds Vaccines Offer High Protection Against Hospitalisation from Delta Variant
▫️Covid-19 Vaccines Made by Pfizer And AstraZeneca Offer High Protection of More Than 90% Against Hospitalisation from The Delta Coronavirus Variant, A New Analysis by Public Health England (PHE) Showed on Monday.
▫️PHE Said That The Pfizer-BionTech Covid-19 Vaccine Was 96% Effective Against Hospitalisation from The Delta Variant After Two doses, While AstraZeneca's Offered 92% Protection Against Hospitalisation by Delta.
▫️PHE Said That Those Levels Of Protection Were Comparable To That Against The Alpha Variant, First Identified In Kent, Southeast England.
▫️The Analysis Adds To Evidence That, Although The Delta Variant Reduces The Effectiveness of Vaccines Against Symptomatic Infection, Two doses of Covid-19 Vaccine Still Protect Against Severe Disease.
▫️The PHE Findings Follow A Scottish Study Which Showed That Two doses of A Covid-19 Vaccine Among People Who Tested Positive Cut Their Risk of Hospitalisation by 70%, Although There Were Not Enough Hospital Admissions Reported To Compare The Vaccines.

Delta Variant Doubles Risk of Covid-19 Hospitalization
▫️The Delta Variant of The Coronavirus First Identified In India May Double The Risk of Hospitalization Among Covid-19 Patients, Compared With The Alpha Variant First Discovered In The UK, A Study from Scotland Suggests.
▫️Researchers Looked At 19,543 Covid-19 Cases And 377 Hospitalizations Among 5.4 Million People, Including 7,723 Cases And 134 Hospitalizations In Patients With The Delta Variant, Who Tended To Be Younger And More Affluent.
▫️The Risk of Covid-19 Hospital Admission Was About Double With The delta Variant Compared To The Alpha Variant, With The Risk Particularly Increased In Those With Five Or More Medical Conditions Known To Contribute To More Severe Disease, The Researchers Reported on Monday In The Lancet.
▫️They Found That Two doses of The Vaccines from Pfizer-BioNTech And from Oxford-AstraZeneca Still Provide Strong Protection, Although Not As Strong As The Protection Provided Against The Alpha Variant (B.1.1.7).
▫️Two Weeks After The Second dose, The Pfizer-BioNTech Vaccine Was found To Provide 79% Protection Against Infection from The Delta Variant, Compared To 92% Against The Alpha Variant.
▫️With Oxford-AstraZeneca's Vaccine, There Was 60% Protection Against Delta Variant Compared With 73% for Alpha. Because This Was An Observational Study, More Research Is Needed To Confirm The Findings, The Research Team Said.

▫️The Vaccine Shows 92% And 86% Efficiency Against Hospitalization In Delta And Alpha Variant Cases, Respectively.
▫️Developed by The University of Oxford, Along With Vaccitech, The Vaccine Utilizes A Weakened Adenovirus And Has The SARS-CoV-2 Virus Spike Protein Genetic Material.
- On Vaccination, The Surface Spike Protein Is Generated, Which Prepares The Immune System To Fight SARS-CoV-2 on Contracting Covid-19.
▫️The New Real-World Data from Public Health England (PHE) Showed That Two doses of Covid-19 Vaccine Oxford-AstraZeneca Had 92% Efficiency Against Hospitalization In Delta Variant Cases.
▫️No Deaths Were Reported Among Those Inoculated With The Vaccine, The Company Noted.
▫️The Analysis Was Conducted on 14,019 Cases of The Delta Variant Observed Between 12 April And 4 June This Year In England.
▫️Furthermore, The Vaccine Was Effective Against The Alpha Variant Or B.1.1.7 And Decreased Hospitalisation by 86% With No Deaths Observed.
▫️The Data Also Showed That The Vaccine Had Lower Effectiveness Against Milder Symptomatic Covid-19. The Effectiveness Was 74% And 64% Against Symptomatic Disease by The Alpha And Delta Variants, Respectively.

Regeneron's Antibody Cocktail Saves Lives In Hospitalised Covid-19 Patients
▫️A Covid-19 Antibody Cocktail Developed by Regeneron Pharmaceuticals Inc And Roche Reduced Deaths In Hospitalised Patients Whose Own Immune Systems Had Failed To Produce A Response, A Large British Study At The University of Oxford Found on Wednesday.
▫️The Researchers Found That Regeneron’s REGEN-COV Reduced The Risk of 28-day Mortality by 20% In Patients Hospitalised With Covid-19 Who Had Not Mounted Their Own Immune Response And Tested Negative for Antibodies. These Patients Are Known As Seronegative.
▫️The Study Involved 9,785 Patients Hospitalised With Covid-19 In Hospitals Across The UK. One-Third Showed No Trace of Producing Their Own Antibodies. In This Seronegative Group, Mortality Was 30% Among Those Who Received Standard Clinical Care But Dropped to 24% Among Those Given An Intravenous Infusion of 8,000mg of REGEN-COV.
▫️REGEN-COV Is A Cocktail of Two Monoclonal Antibodies, Casirivimab With Imdevimab, Designed To Block The Infectivity of SARS-CoV-2. The Two Antibodies Work by Binding To Two Different Points on The Coronavirus Spike Protein, Neutralising The Ability of The Virus To Infect Cells.
▫️Previous Phase III Trials In Non-Hospitalised Covid-19 Patients Demonstrated That REGEN-COV “Reduced Viral Levels, Shortened The Time To Resolution of Symptoms And Significantly Reduced The Risk of Hospitalisation Or Death.”

FDA Approves Mallinckrodt’s StrataGraft For Thermal Burns Treatment
▫️The US Food And Drug Administration (FDA) Has Approved Mallinckrodt’s StrataGraft To Treat Adults With Thermal Burns Comprising Intact Dermal Elements.
▫️StrataGraft Is Made from Two Types of Human Skin Cells, Keratinocytes And Dermal Fibroblasts, Cultured Together To Create A Bi-Layered Construct Or A Cellularised Scaffold.
▫️The FDA Approval Is Backed by Data from The Phase III STRATA2016 Clinical Trial of A Single StrataGraft Application In Patients With Deep Partial-Thickness Burns.
▫️According To The Trial Results, A Significantly Lesser Area of Burn Wounds Treated With StrataGraft Needed Autografting by Three Months Versus The Area Of Wounds Treated Only With Autograft.
▫️Furthermore, 96% Of The Burn Sites Treated With The Product Did Not Need Autografting In All Subjects.
- A Difference of 98% Was Noted In The Per cent Area of StrataGraft Versus Control Autograft Treatment Sites That Needed Autografting by Three Months.
- In Addition, Nearly 83% of The Patients Had Durable Closure of The StrataGraft Treatment Site At Three Months Without Needing An Autograft Placement.

Alzheimer’s Vaccine Shows Promise In Phase II Trial
▫️New Phase II Data Suggests AXON Neuroscience’s "Tau Vaccine", AADvac1, Was Safe, Well Tolerated And Generated An Exceptional Tau Antibody Response In Alzheimer’s Disease (AD) Patients.
▫️Hyper-Phosphorylated Tau Accumulated In Neurofibrillary Tangles (NFT) Is One of The Hallmarks of AD, Alongside Amyloid beta Plaques. NFT Has Been Shown To Be Linked To Neuronal Loss And Brain Atrophy.
▫️The Phase II ADAMANT Trial Was A 24-Month Placebo-Controlled, Randomised, Parallel Group, Double-Blinded, MultiCentre Study of AADvac1, An Active Immunotherapy Against Pathological Tau, In AD Patients With Mild Disease.
▫️The Trial Met Its Primary Endpoint, With The Vaccine Being Safe And Well Tolerated. Serious Adverse Events Occurred In 17.1% of AADvac1-Treated Individuals And 24.1% of Placebo-Treated Individuals; And Adverse Events Were Observed In 84.6 Percent of The AADvac1 Arm And 81 Percent of Placebo Arm.
▫️In Terms of Its Secondary Endpoints; The Vaccine Was Found To Induced High Levels of Immunoglobulin G (IgG) Antibodies; Significantly Reduce The Accumulation of Neurofilament Light Chain (NfL), An Important Biomarker of Neurodegeneration, In The Blood by 58 Percent; And Diminish Other Core AD Cerebrospinal Fluid (CSF) Biomarkers of Tau Pathology And Tau Neurodegeneration, Including The Most Specific CSF Biomarker Phosphotau-T217.
