Partner of the Month: The Foundation for Alternative and Integrative Medicine (FAIM)

September 30, 2020

The Foundation for Alternative and Integrative Medicine (FAIM) provides a service to the field of alternative and integrative medicine by educating the public with cutting edge information through collaboration with experts in the field and by assisting researchers and practitioners in research evaluating promising therapies and theories in natural health care.  The FAIM website serves as an umbrella for experts in all areas listed in the website Health Topics to share the latest in natural medicine.  This information is offered free to the public at large.

FAIM strives to promote education and research in the areas of new frontiers in science and technology in natural health care.  This would include health related discoveries which hold promise and efficacy.  FAIM publishes these reports on the FAIM website and communicates the research findings reaching the public and professionals.

Research of technologies that are sometimes considered unconventional, still hold the potential of contributing to the paradigm shift in medicine and thus offer a platform to be researched to confirm efficacy.  Documenting these technologies offers a service to natural health care and the future.

Progress in the field of complementary and alternative medicine is frustratingly slow. This is due, in part, to practitioners who lack preliminary data beyond patient testimonials. Slow progress may also be attributed to limited financial resources and inadequate research capacity.  Therefore, FAIM provides a service to the field by assisting researchers and practitioners in collecting outcome data.

FAIM is committed to research to obtain the most valuable data. Knowing the limitations of research due to funding restrictions, FAIM is developing collaborations with research facilities nationally and internationally where it can conduct research on therapies and technologies. In the case of international collaborations, the research would benefit the country from the knowledge revealed.  This research could lead the way towards real breakthroughs in world health.  FAIM is eager to collaborate with groups within and outside the U.S. who have the research capacity and interest in advancing investigations of non-toxic, innovative, and cost-effective therapies for conditions with a large public health impact.

Common Class of Medications Linked to AD, MCI Risk 

September 24, 2020

Several types of medications have been linked to mild cognitive impairment and Alzheimer’s disease (AD) risk in older patients over the years. A growing body of evidence points to drugs with anticholinergic effects as particularly dangerous for certain patient demographics. Emerging results from a recent study indicate that there may be a significant association between anticholinergic medications, AD biomarkers, and the incidence of mild cognitive impairment among cognitively normal older adults.

Anticholinergic Medications

Anticholinergic drugs have been widely used for a variety of medical conditions, ranging from allergies and the common cold to the treatment of hypertension. While certain anticholinergic medications require a prescription, others can be easily purchased over the counter.

This class of medications works by blocking acetylcholine, a neurotransmitter critical for memory function, from binding to receptors on certain nerve cells thereby inhibiting parasympathetic nerve impulses, which underlie involuntary muscle movements and bodily functions.

Examining the Relationship 

A team of researchers aimed to determine whether there were any cognitive consequences of anticholinergic medications (aCH) among a group of cognitively normal older patients and whether the interactive effects of genetic and cerebrospinal fluid (CSF) Alzheimer’s disease (AD) risk factors had any influence.

Led by Alexandra Weigand at the UC San Diego School of Medicine, the team of researchers assessed 688 cognitively normal participants from the Alzheimer’s Disease Neuroimaging Initiative with a mean age of 73.5 years. None of the participants presented with any cognitive or memory problems at the time of study inception. Approximately one-third of patients was taking anticholinergic medications with an average of 4.7 aCH drugs per person. The study’s authors administered comprehensive cognitive tests annually for all participants.

Cox regression models were used to examine the risk of progression to mild cognitive impairment (MCI) over a 10-year period, while linear mixed effects models were utilized to evaluate 3-year rates of memory, executive, and language function as related to anticholinergic medication administration.

Association of Anticholinergic Drugs with AD and MCI

According to the study’s findings published in Neurology, participants with AD biomarkers who were taking anticholinergic medications were up to four times more likely to develop mild cognitive impairment than those lacking biomarkers and not taking aCH drugs. Similarly, participants who were at a genetic risk for Alzheimer’s disease who took anticholinergic medications were up to 2.5 times more likely to develop MCI than those without genetic risk factors who were not taking the medications.

Further, linear mixed effects models found that anticholinergic medications predicted a steeper slope of decline in memory and language functions. This was especially true for participants with AD risk factors, in which the effects were exacerbated.

Researchers believe that the association acts in a “double hit manner” :”In the first hit, Alzheimer’s biomarkers indicate that pathology has started to accumulate in and degenerate a small region called the basal forebrain that produces the chemical acetylcholine, which promotes thinking and memory. In the second hit, anticholinergic drugs further deplete the brain’s store of acetylcholine.” Overall, the combined effect can have a severe impact on a patient’s thinking and memory.

Clinical Implications 

The latest findings implicate an increased risk of incident MCI and cognitive decline as related to anticholinergic medications with effects significantly exacerbated in patients with existing genetic risk factors and CSF-based biomarkers. These results “underscore the adverse impact of these drugs on cognition and the need for deprescribing trials, particularly among individuals with elevated risk for AD,” the study’s authors wrote, emphasizing the importance of further evaluation to determine whether reductions in drug usage can lead to reductions in MCI progression.

However, the researchers also noted that anticholinergic medications were being taken at levels much higher than the lowest effective dose recommended for older patients; 57% of participants were taking twice the recommended dosage while 18% were taking at least four times the recommended dose.

As the findings suggest, reducing anticholinergic drug consumption may help delay age-related cognitive decline. According to senior author and associate professor at the UC San Diego School of Medicine Lisa Delano-Wood, PhD, the latest study “suggests that reducing anticholinergic drug use before cognitive problems appear may be important for preventing future negative effects on memory and thinking skills, especially for people at greater risk for Alzheimer’s disease.”

While the current evidence indicates a clear association between anticholinergic medications and cognitive effects, further research efforts are needed to determine whether these agents are able to accelerate cognitive changes or lead to the development of Alzheimer’s disease and other neurodegenerative disorders.

Estrogen & COVID-19 Severity in Women

September 17, 2020

Growing clinical evidence reveals that the intensity of COVID-19 infection and incidence of related complications are more prominent in male patients. Current data suggests that men experience a greater risk than women for more severe COVID-19 symptoms and poorer outcomes regardless of their age. These burgeoning findings signal that sex may function as a determinant of COVID-19 infection severity.

While the body of evidence examining sex differences in virus outcomes is lacking, researchers believe the functional modulation of angiotensin-converting enzyme 2 by estrogen may explain disparities in morbidity and mortality. Further reasons for higher male sex-specific COVID-19-related mortality are likely multi-fold and may include lifestyle differences such as higher rates of tobacco smoking and alcohol consumption as well as innate immunity. The mounting evidence suggesting sex-based differences in clinical outcomes emphasizes the need for an assessment of sex-specific hormone activity – in particular, estrogen – in COVID-19 pathogenesis.

Sex-Specific Differences in COVID-19 Outcomes 

A recent study conducted by researchers at the Wake Forest Baptist Medical Center attempts to elucidate the mechanisms underlying these notable differences. Led by Leanne Groban, MD, professor of anesthesiology at Wake Forest School of Medicine, a team of researchers conducted a review of published literature to determine whether sex plays a role in COVID-19 outcomes by examining pre-clinical data on sex-specific hormone activity.

Beneficial Impact of Estrogen

The study’s authors reported that angiotensin-converting enzyme 2 – attached to cell membranes in heart, arteries, kidneys, and intestines – acts as a cellular receptor of the coronavirus responsible for COVID-19 infections and helps the virus gain access to cells of those organ systems. According to the researchers, their review also pointed to estrogen’s impact on ACE2 levels in the heart; the hormone lowered ACE2 levels. This may modulate the severity of COVID-19 in women, while higher levels of ACE2 present in tissues could account for why the disease presents worse in men.

“We know that coronavirus affects the heart and we know that estrogen is protective against cardiovascular disease in women, so the most likely explanation seemed to be hormonal differences between the sexes,” said the lead author of the review, Dr. Groban told ScienceDaily in an interview.

“We hope that our review regarding the role of estrogenic hormones in ACE2 expression and regulation may explain the gender differences in COVID-19 infection and outcomes and serve as a guide for current treatment and the development of new therapies,” Groban said.

An enhanced understanding of the role of estrogenic hormones in ACE2 expression and regulation may not only help uncover potential mechanisms that explain sex differences in COVID-19 clinical outcomes, but also guide future disease management techniques and spur the discovery of novel therapeutic methods.
