Long-COVID Update: clinical manifestations and treatment strategies for Vagus Nerve injuries

5+ years into the disastrous COVID pandemic, concern over acute viral infection has taken a back seat to the increasingly complex and treatment-resistant Long-COVID presentations. Perhaps the most debilitating of these are the spike-protein induced Vagus Nerve injuries which have the potential to affect each body system regulated by the parasympathetic nervous system. The diversity of symptoms can therefore cross neurologic, cardiovascular, gastrointestinal and pulmonary systems and necessitates a conceptual, root-cause oriented approach to treatment. In this lecture we will use case studies to describe common presentations of Vagus Nerve dysfunction and the mechanisms of action driving the disease process as well as strategies for healing nervous system tissue, nerve transmission and depleted immune function.

How to Be a High Functioning Empath

This lecture describes what it means to be an empath (aka a highly sensitive person) and speaks to strategies and practices to support someone who identifies as highly sensitive. Drawing from ancient philosophies such as Taoism, Qi Gong, and other traditional practices, this lecture describes (using meridian based anatomy and Traditional Chinese Medicine Theory) how and why someone is impacted energetically by interpersonal interactions. Subsequently, I will describe what one can do to reduce the challenges of this energetic reality by offering tools and strategies to strengthen energetic boundaries and improve energetic hygiene. This lecture is aimed at providers – who are often sensitive an empathic – and offers strategies to help reduce burnout risk. Additionally, these tools and practices can be offered to patients.

Impact of Maternal Immune Activation and Infections in Pregnancy on Newborn Outcomes and Longterm Child Health

It is well known that infections in pregnancy such as Rubella and Syphilis can cause pregnancy complications, birth defects and developmental delays. More recently with the increasing rates of Lyme disease, research is showing transmission during pregnancy to the newborn. Research on Lyme in pregnancy has shown increased risk of pregnancy complications such as premature birth and IUGR which both lead to an increased risk of long term health outcomes in the child. For the newborn, the most common complications are skin rashes, low muscle tone and respiratory distress. The question then becomes what mechanisms are involved in the pathology of these issues. During pregnancy, the immune system changes to prevent the mother’s immune system from attacking the fetus. This involves shifts in the immune system leading to a greater risk of infections and increased rates of inflammation. As part of the immune changes, immunoglobulin G (IgG) can transfer protection to the fetus. Research is showing that some pregnant women have maternal autoantibodies that can pass to the fetal brain and lead to abnormal brain development. To date eight maternal autoantibodies have been discovered. Research is showing that these maternal autoantibodies can lead to an increase in rates of autism in children. Awareness of these immune and infection issues for the mother and child can lead to more preventative and treatment strategies.

The Power of Light: Advancing Pain Management with Photobiomodulation

Photobiomodulation therapy (PBMT), formerly known as low-level laser therapy (LLLT), has emerged as a non-invasive and evidence-based modality for the treatment of acute and chronic pain. By using red and near-infrared light to modulate cellular function, PBMT promotes tissue repair, modulates/reduces inflammation, and alters pain signaling pathways. This presentation aims to provide an overview of the mechanisms of PBMT, review the current evidence for its efficacy in various pain syndromes, and discuss practical considerations for clinical application.

PBMT influences cellular metabolism primarily through the absorption of photons by cytochrome c oxidase in the mitochondria. This interaction enhances adenosine triphosphate (ATP) production, modulates reactive oxygen species (ROS), and initiates cellular signaling cascades that lead to immuno-modulatory and analgesic effects. Clinical studies have demonstrated significant benefits of PBMT in conditions such as musculoskeletal pain, neuropathic pain, and postoperative discomfort, with minimal adverse effects reported. Despite its promising therapeutic potential, discrepancies in treatment protocols — including wavelength, dosage, and application technique — pose challenges in standardization and broader adoption.

Dr. Nathaniel Shober, ND, specializes in regenerative medicine. He earned his Doctorate in Naturopathic Medicine from Bastyr University in 2016.

Translating Cardiometabolic Science into Root-Cause Care

Cardiovascular disease remains the leading cause of death worldwide — yet it is often preventable with timely intervention, especially through a naturopathic approach that emphasizes root-cause assessment and individualized care. As rates of obesity, metabolic syndrome, and insulin resistance rise, traditional screening tools such as fasting glucose and lipid panels often fall short in identifying patients at greatest risk.

This session bridges cutting-edge science with naturopathic philosophy, exploring the use of advanced lipid and metabolic markers — including oxidized LDL-C, small dense LDL-C, non-HDL-C, apolipoprotein B, leptin, and 1,5-anhydroglucitol — to deliver targeted preventive therapeutics and lifestyle modifications. Through real-world patient cases, participants will gain actionable clinical pearls on how to detect atherosclerotic and metabolic disease earlier, implement individualized behavioral and nutritional strategies, and guide patients toward sustainable cardiometabolic health.

We will also address the physiological impact of popular dietary trends like the ketogenic diet and how they impact biomarkers of cardiometabolic risk. Attendees will leave equipped to interpret precision lab results and integrate this data into holistic, patient-centered care plans — extending both lifespan and healthspan.

Opportunities and Risks in the Evolving Medical Hemp Industry

The cannabis plant contains numerous therapeutic compounds with clinical applications, some supported by high-quality clinical data, and others that are emerging and experimental. Originally dominated by CBD-rich products, the hemp industry currently sells a variety of product classes directly to consumers, without a requirement for a medical provider’s supervision. These products have the potential to interact with other treatments, and it is beneficial for clinicians to be able to competently discuss the use of these products with their patients. Furthermore, clinicians and their patients can benefit from an understanding of the established or potential utility of these products, and to recognize and mitigate associated risks.

Medical and adult use cannabis regulations and product availability vary widely among state jurisdictions, and despite their likelihood of being the best candidates for supervising cannabis-using patients, naturopathic physicians are often unable to provide medical cannabis certifications. Thus, many of their patients may turn to hemp products to avoid the logistical challenges of the medical and adult-use markets.

Among the therapeutic opportunities in the current hemp market, CBG-dominant, THC-containing, and acidic cannabinoid products provide distinct opportunities for patients. Conversely, a wide variety of chemically-manipulated hemp products have also emerged, many with concerning safety profiles.

In this presentation, Dr. Sulak will demonstrate examples of the use of novel therapeutic hemp products, and the clinical and preclinical data to support these therapeutic strategies. He will include currently unpublished data on over 200 people using CBG-dominant products as well as findings from a large cohort of individuals currently using hemp products to treat dementia-related symptoms. Finally, Dr. Sulak will review the dangers lurking in the hemp marketplace and strategies for helping patients find safe products.
