Balamuthia mandrillaris is an under-reported, pathogenic free-living amoeba that causes Balamuthia amoebic encephalitis (BAE) and cutaneous skin infections. Although cutaneous infections are not typically lethal, BAE with or without cutaneous involvement is usually fatal. This is due to the lack of drugs that are both efficacious and can cross the blood-brain barrier. We aimed to discover new leads for drug discovery by screening the open-source Medicines for Malaria Venture (MMV) Malaria Box and MMV Pathogen Box, with 800 compounds total. From an initial single point screen at 1 and 10 μM, we identified 54 hits that significantly inhibited the growth of B. mandrillaris in vitro. Hits were reconfirmed in quantitative dose-response assays and 23 compounds (42.6%) were confirmed with activity greater than miltefosine, the current standard of care.

We report a systematic, cellular phenotype-based antimalarial screening of the Medicines for Malaria Venture Pathogen Box collection, which facilitated the identification of specific blockers of late-stage intraerythrocytic development of Plasmodium falciparum. First, from standard growth inhibition assays, we identified 173 molecules with antimalarial activity (50% effective concentration [EC₅₀] ≤ 10 μM), which included 62 additional molecules over previously known antimalarial candidates from the Pathogen Box. We identified 90 molecules with EC₅₀ of ≤1 μM, which had significant effect on the ring-trophozoite transition, while 9 molecules inhibited the trophozoite-schizont transition and 21 molecules inhibited the schizont-ring transition (with ≥50% parasites failing to proceed to the next stage) at 1 μM. We therefore rescreened all 173 molecules and validated hits in microscopy to prioritize 12 hits as selective blockers of the schizont-ring transition. Seven of these molecules inhibited the calcium ionophore-induced egress of Toxoplasma gondii, a related apicomplexan parasite, suggesting that the inhibitors may be acting via a conserved mechanism which could be further exploited for target identification studies. We demonstrate that two molecules, MMV020670 and MMV026356, identified as schizont inhibitors in our screens, induce the fragmentation of DNA in merozoites, thereby impairing their ability to egress and invade. Further mechanistic studies would facilitate the therapeutic exploitation of these molecules as broadly active inhibitors targeting late-stage development and egress of apicomplexan parasites relevant to human health.

Quality Improvement Success Stories are published by the American Diabetes Association in collaboration with the American College of Physicians, Inc. (ACP), and the National Diabetes Education Program. This series is intended to highlight best practices and strategies from programs and clinics that have successfully improved the quality of care for people with diabetes or related conditions. Each article in the series is reviewed and follows a standard format developed by the editors of Clinical Diabetes. The following article describes an initiative of the Cleveland Clinic’s internal medicine residents to improve diabetes care and outcomes within an underserved patient population at an East Cleveland, OH, health center.

Consistently, the field of genetic counseling has advocated that parents be advised to defer elective genetic testing of minors until adulthood to prevent a range of potential harms, including stigma, discrimination, and the loss of the child's ability to decide for him- or herself as an adult. However, consensus around the policy of "defer-when-possible" obscures the extent to which this norm is currently under siege. Increasingly, routine use of full or partial genome sequencing challenges our ability to control what is discovered in childhood or, when applied in a prenatal context, even before birth. The expansion of consumer-initiated genetic testing services challenges our ability to restrict what is available to minors. As the barriers to access crumble, medical professionals should proceed with caution, bearing in mind potential risks and continuing to assess the impact of genetic testing on this vulnerable population.

As interest in the application of plasma medicine -- the use of low-temperature plasma (LTP) created by an electrical discharge to address medical problems -- continues to grow, so does the need for research advancements proving its capabilities and potential impacts on the health care industry. Across the world, many research groups are investigating plasma medicine for applications including cancer treatment and the accelerated healing of chronic wounds, among others.

Broad modifications to current standards for treating acute stroke patients during the COVID-19 pandemic may be needed to preserve health care resources, limit disease spread and ensure optimal care, according to a Loyola Medicine neurologist.

The FDA warns that President Trump's much-touted coronavirus drugs could cause deaths. The White House says media 'irresponsibly' reported his words.

The European Medicines Agency’s Pharmacovigilance Risk Assessment Committee (PRAC) has confirmed that the risks from using Picato are too high to end its suspension.

Florida-based American Sleep Medicine LLC has agreed to pay $15,301,341 to resolve allegations that it billed Medicare, TRICARE – the health care program for Uniformed Service members, retirees and their families worldwide – and the Railroad Retirement Medicare Program for sleep diagnostic services that were not eligible for payment.

"One of our top priorities is addressing youth violence. As I’m sure many of you would agree, this is one of the most complex and intractable problems in criminal justice. And because it is so complex, we’ve learned over time that tackling it involves many people – stakeholders from all sectors and from all levels of government," said Acting Assistant Attorney General Leary.

The Justice Department announced today that it has reached a settlement with the University of Medicine and Dentistry of New Jersey School under the Americans with Disabilities Act.

Posted by Roger Bate A Star Newspaper investigation of drug quality in Canada (see here) demonstrates the risks patients in rich nations like Canada run from receiving poor quality medicines, especially imported from India. What is most worrying is the lack of transparency at some western health agencies. What the investigation shows is that Health Canada has hidden information about problems with medications. While it is true that educated people occasionally make bad medicine choices (think [...]

Posted by Roger BateThe World Health Organization just posted its new report on inferior medicines (http://apps.who.int/gb/ebwha/pdf_files/WHA68/A68_33-en.pdf). It is called the member state mechanism (MSM) report on Substandard/spurious/falsely-labelled/falsified/counterfeit medical products - SSFFC for short. This report is the culmination of multiple meetings of health bureaucrats to finalize how to combat inferior medicines. Or rather that is what one hoped for when the SSFFC process began [...]

With a generous support from the Guangzhou City Government and the Guangdong Provincial Government, Guangzhou Regenerative Medicine and Health-Guangdong Laboratory (GRMH-GDL) was launched in 2017. GRMH-GDL aims to bring together multiple leading scientific research units from Guangdong, Hong Kong, Macao and well-known international research institutes to achieve the vital goal of "Healthy China" and to cooperatively tackle the scientific and technical problems and challenges. GRMH-GDL is focused…

For decades westerners have lectured central and eastern European policymakers on how to regulate and supervise, balance their budgets and stem credit expansion. Now they must deal with the consequences of a global crisis triggered because the west broke all the rules it preached. Worse, it is a crisis they cannot do much to resolve.…
