Cardiac and vascular point-of-care ultrasound: current situation, problems, and future prospects
AbstractAlthough clinical application of ultrasound to the heart has a history of about 80  years, its big turning point was the emergence of a portable ultrasound diagnostic machine. As a result, the place, where echocardiography is performed widely spread outside the examination room, and the people who perform echocardiography have also greatly increased. Emergency physicians, anesthe siologists, and primary care physicians became interested in echocardiography and started using it. Such ultrasound examinations performed by a doctor for assessment of disease condition, management, or guidance of treatment at bedside ha...

Molecules, Vol. 27, Pages 1740: Virtual Screening of Natural Chemical Databases to Search for Potential ACE2 Inhibitors
In this study, structure- and property-based virtual screening methods were combined to filter natural product databases from ChemDiv, TargetMol, and InterBioScreen to find potential ACE2 inhibitors. The binding affinity between protein and ligands was predicted using both Glide SP and XP scoring functions and the MM-GBSA method. ADME properties were also calculated to evaluate chemical drug-likeness. Then, molecular dynamics (MD) simulations were performed to further explore the binding modes between the highest-potential compounds and ACE2. Results showed that the compounds 154-23-4 and STOCK1N-07141 possess potential AC...

Telehealth: A winning weapon to face the COVID-19 outbreak for patients with pulmonary arterial hypertension
CONCLUSION: Italy was found unprepared to manage the dramatic effects caused by COVID-19 on healthcare systems. In this emergency situation telemedicine represented a promising tool especially in rare diseases as PAH, but was limited by its scattered availability and legal and ethical issues. Cohesive partnership of health care providers with regional public health officials is needed to prioritize PAH patients for telemedicine by dedicated tools.PMID:35716991 | DOI:10.1016/j.vph.2022.107024

Viruses, Vol. 15, Pages 580: Search of Novel Small Molecule Inhibitors for the Main Protease of SARS-CoV-2
Lin The current outbreak of coronavirus disease 2019 (COVID-19) has prompted the necessity of efficient treatment strategies. The COVID-19 pandemic was caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Main protease (Mpro), also called 3-chymotrypsin-like protease (3CL protease), plays an essential role in cleaving virus polyproteins for the functional replication complex. Therefore, Mpro is a promising drug target for COVID-19 therapy. Through molecular modelling, docking and a protease activity assay, we found four novel inhibitors targeting Mpro with the half maximal inhibitory concentratio...

Best Practice Recommendations for Stroke Vascular Imaging During Iodinated Contrast Shortage
GE Healthcare© announced on April 19, 2022, that their main factory and distributor of iodinated contrast had experienced a temporary shutdown because of COVID-19 outbreak in Shanghai, China. This, along with other supply chain issues, led to a worldwide shortage of iodinated contrast agents, Omnipaque and Visipaque. Our Comprehensive Stroke Center was confronted with the cascading effect of this iodinated contrast material shortage. We took immediate steps to revise our protocols and processes to continue to provide high-quality care to our stroke patients. A multidisciplinary working group comprised of representativ...

Fight Aging! Newsletter, August 15th 2016
In conclusion, our results demonstrate that circulating GDF11 levels are reduced in our mouse model of premature aging, which shares most of the symptoms that occur in normal aging. However, GDF11 protein administration is not sufficient to extend longevity in these progeroid mice. Although accelerated-aging mouse models can serve as powerful tools to test and develop anti-aging therapies common to both physiological and pathological aging, the existence of certain differences between the two processes implies that further investigation is still required to determine whether long-term GDF11 administration has a pro-surviva...

Aedes –Chikungunya Virus Interaction: Key Role of Vector Midguts Microbiota and Its Saliva in the Host Infection
Conclusion and Perspectives Arbovirus infections, such as CHIKV, have been growing worldwide and are becoming a major public health problem, especially in immuno-compromised classes such as children and the elderly. CHIKV is dangerous since it can cause arthritis, fever and other impairments, making it necessary to seek new ways to counter the proliferation of this virus. Knowing the vector’s competence is fundamentally important, including an understanding of the vector virus interaction and the modulation of this interaction. Despite advances in the knowledge of mosquito competence in the transmission of CHIKV, l...

Critical Care Compendium update
LITFL’s Critical Care Compendium is a comprehensive collection of pages concisely covering the core topics and controversies of critical care. Currently there are almost 1,500 entries with more in the works… Some pages are more developed than others, and all the pages are being constantly revised and improved. Links to new references and online resources are added daily, with an emphasis on those that are free and open access (FOAM!). These pages originated from the FCICM exam study notes created by Dr Jeremy Fernando in 2011, and have been updated, modified and added to since. As such will be particularly us...

Can Gingko and Turmeric Help Stop Ebola?
Summary There is no known pharmaceutical currently available that specifically treats Ebola disease. One treatment modality that should be considered is the use of herbal medicines, which have both centuries old anecdotal success as well as recent modern biochemical and formal research rationales for their use. Five areas of action that could be addressed by the herbal medicines as it relates to Ebola would be: VP24/immune system evasion GP protein/replicatio; herbal strategies effective against similar hemorrhagic disease beneficial modulation of patient immune and inflammatory response systems prophylactic use for heal...

Credit: Tristate Heart and Vascular CentreBy Pavithra Rao, Africa Renewal*NEW YORK, Sep 28 2017 (IPS)In the 2017 World Happiness Report by Gallup, African countries score poorly. Of the 150 countries on the list, the Central African Republic, Tanzania and Burundi rank as the unhappiest countries in the world. Some of the factors driving unhappiness are the poor state of the continent’s health care systems, the persistence of HIV/AIDS, malaria and tuberculosis, and the growth of lifestyle diseases such as hypertension, heart disease and diabetes.Few African countries make sig...

Human and plant volatiles; lures for mosquito, vectors of dengue virus and malaria
J Vector Borne Dis. 2021 Jan-Mar;58(1):1-11. doi: 10.4103/0972-9062.318313.ABSTRACTIncreased outbreaks of mosquito borne diseases like the deadly parasitic disease, malaria and arboviruses like Zika, yellow fever and dengue viruses around the world have led to increased interest in traps that could effectively be used against mosquitoes. For example, a Google search at the time of this writing, asking, 'which is the best way of trapping mosquitoes?' produced 35.5 million search results. Regardless of the interest in the subject, scientists have yet to find a definitive answer to these questions. One area that has been expl...
