Associate Professor Jennifer Hunter is an academic general practitioner with a clinical interest in integrative medicine, has received payment for providing expert advice about traditional, complementary and integrative medicine, including nutraceuticals, to industry, government bodies and non-government organisations, and spoken at workshops, seminars and conferences for which registration, travel and/or accommodation has been paid for by the organisers.
MedicalResearch.com: What is the background for this study?
Response: We decided to review the evidence for zinc in response to calls for rapid evidence reviews to inform self-care and clinical practice during the COVID-19 pandemic.
Laboratory studies have found that zinc can inhibit the replication of many respiratory viruses, including SARS-CoV-2 and other coronaviruses. Zinc plays a key role in immunity, inflammation, tissue injury, ACE-2 receptor activity, and also in tissue responses to a lack of oxygen. Low zinc status may be a risk factor for severe SARS-CoV-2 illness.
Additionally, there was some indirect evidence suggesting zinc might be effective for other respiratory tract infections such as the common cold and we wanted to verify this.

MedicalResearch.com: What is the background for this study?
Response: Drug and alcohol related mortality has been on the rise in the US for the past decade, which has drawn a lot of focus from researchers. At the same time maternal mortality, deaths caused by pregnancy complications, is recognized to be higher in the US than in other developed nations.
Very little has been reported about deaths among pregnant and recently pregnant women that are not caused by pregnancy complications, so my collaborators and I wanted to explore this. We did not anticipate that drug and alcohol deaths and homicides would account for so many deaths among pregnant and recently pregnant women.

MedicalResearch.com: What is the background for this study?
Response: Lyme disease presents first on the skin with the classic “bull’s-eye” rash. But such rashes in Black patients aren’t well-represented in medical textbooks. This may lead to physicians not recognizing such rashes in Black patients.
As a result, Black patients are more likely to present with later complications of Lyme disease when first diagnosed such as neurologic complications.
Dr. Mahncke[/caption]
Dr. Mahncke earned his PhD at UCSF in the lab where lifelong brain plasticity was discovered. At the request of his academic mentor, he currently leads a global team of more than 400 brain scientists engaged in designing, testing, refining, and validating the computerized brain exercises found in the BrainHQ app from Posit Science, where he serves as CEO.
Earlier this year, MedicalResearch.com interviewed Dr. Henry Mahncke about the BRAVE Study he led, which showed a digital health app (BrainHQ) was effective in addressing chronic cognitive issues in servicemembers who had been diagnosed with “mild” Traumatic Brain Injury. This week, MedicalResearch.com interviews Dr. Mahncke again about a new independent study among civilians showing similar results in patients with all kinds of Brain Injuries.
MedicalResearch.com: What is the background for this study?
Response: The Centers for Disease Control (CDC) estimates that about 5.3 million people currently live with a chronic disability from a Traumatic Brain Injury (TBI). While most people who suffer a blow to the head recover in a couple days or weeks, for some (estimated as high as 15 percent) the injury persists with a variety of life-disrupting symptoms, including impairments in cognitive abilities, behavior, emotions, and motor function affecting work, relationships, and daily function.
TBIs have been the signature injury of recent wars. Nearly 400,000 service members have been diagnosed with TBIs, of which 82% were diagnosed with so-called “mild” TBIs from concussions and blast injuries. More than a decade ago, we began being asked by military and Veterans organizations, to study whether our brain exercises – which had shown positive effects in measures of cognition, everyday function, mood, and motor function in healthy older adults – could have an impact on people with chronic symptoms from TBIs.
We talked earlier this year, when an 83-person, gold-standard, randomized controlled trial on mTBI (called the BRAVE Study) announced quite positive results from using BrainHQ exercises. That study was funded by the Department of Defense and run as five military and Veterans medical centers. The BRAVE Study found the BrainHQ group showed a statistically and clinically significant improvement on a standard measure of overall cognitive function (compared to a computer games control), and this benefit persisted for at least 12 weeks after training completed. Cognitive function improvements were nearly four times larger in the BrainHQ group than the control (as measured immediately following training) and grew to nearly five times larger (when measured again 12 weeks after training ended). On average, participants in the BrainHQ group improved on the cognitive performance composite measure by 24 percentile ranks – as though they went from the 50th percentile to the 74th percentile.
One large question left unanswered from the BRAVE study was whether this approach might also work for other categories of TBIs, such as moderate and severe TBIs. A new study from independent researchers at NYU answers that question.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Preeclampsia is one of the most serious health problems that can occur during pregnancy. It can lead to preterm birth, and in some cases even death of the pregnant person and their baby.
The Task Force looked at the latest available evidence and found that low-dose aspirin can help prevent preeclampsia in pregnant people who are at highest risk, and it can also protect their babies. This new final recommendation is consistent with the Task Force’s 2014 recommendation statement and has the potential to save many lives.

MedicalResearch.com: What is the background for this study?
Response: Medications are generally safe when used as prescribed or as directed on the label, but there can be risks in taking any medication. Adverse drug events are harms resulting from the use of medication.
The risk of adverse drug events is highest among older adults and very young children. Older adults have higher risks because they typically take more medications and are more likely to have underlying medical conditions. Very young children have higher risks because they often find and ingest medications meant for others.
Previous studies of medication safety have focused on harm from medications when taken for therapeutic reasons. Separate studies have focused on harm from specific types of non-therapeutic use (taking medications for recreational use or self-harm). This study examined the number of emergency department (ED) visits that resulted when people who took medications for any reason – as directed by a clinician or for other reasons, including recreational use or intentional self-harm.

MedicalResearch.com: What is the background for this study?
Response: Psoriasis is a chronic, immune mediated skin disease for which effective targeted biological agents have become available the past years. Inherent to their immunomodulatory mechanism of action, biologics might increase infections risk. We know from clinical trial data that respiratory tract infections are among the most common adverse events during biologic treatment, but real-world data is sparse. Regarding the risk of serious infections among biologic users, mostly defined as infections requiring hospitalization, previous studies provided different results and there is limited comparative data for the newer biologics available.
The COVID-19 pandemic turned attention to the risk of infections among biologic users, especially for respiratory tract infections, as they might relate to susceptibility for viral respiratory tract infections such as COVID-19.
In our study, the primary aim was to determine the risk of respiratory tract infections among real-world psoriasis patients treated with biologics, including the newer IL-17 and IL-23 inhibitors. The secondary aim was to assess risk of serious infections in this cohort. Additionally, rates of SARS-CoV-2 infections were assessed.
