Intriguing Comments on Depression

From Thomas Tsangaras:

โ€œDepression is your body saying:
โ€˜I donโ€™t want to be this character anymore.โ€™โ€

โ€œI donโ€™t want to be this character anymore.โ€

So many people quietly say that line.

Not just in the context of mental health
but in the context of work, identity, and environments.

Sometimes what we call burnout or depression
is actually something deeper:

Staying too long in a role that isnโ€™t ours.
Performing instead of being.
Wearing a mask because it once worked.

The problem is this:
pretending takes enormous energy.
Authenticity takes almost none.

Some jobs feel like an extension of who we are.
Some environments drain us quietly, over years.

And often the body speaks up
before the mind is ready to listen.

Thatโ€™s why alignment matters.
Not for productivity but for longevity.

Beyond the 16-Week Snapshot: Why Data Snapshots Mask the Reality of Chronic Therapy

Beyond the 16-Week Snapshot: Why Data Snapshots Mask the Reality of Chronic Therapy

In my independent review of the CARES-310 trial (Camrelizumab-Rivoceranib), I analyzed a common pitfall in modern drug development: the reliance on 16-week primary endpoints to justify long-term therapeutic narratives.

While a 16-week data cut can deliver a clean p-value for a regulatory filing, it often functions as a methodological mirage. In chronic or aggressive immune-mediated diseases, these snapshots can mask:

  1. The Waning Effect: Failure to account for the durability of response after the initial 16-week “honeymoon” period.
  2. The Comparator Trap: Choosing an obsolete or “outdated” standard (like sorafenib) to inflate perceived efficacy.
  3. Clinical vs. Statistical Significance: A statistical “win” for PFSโ€”such as the 2.83-month median seen in certain gastric trialsโ€”may have little clinical importance if it doesn’t provide a meaningful improvement in a patientโ€™s quality of life.

The “Focused AI” Reality As industry leaders pivot from a “thousand flowers” experimentation phase to a prioritized, high-value GenAI strategy, the stakes for data integrity have never been higher. An AI Management System (ISO 42001/AIMS) is only as good as the human-in-the-loop who can identify these methodological vulnerabilities.

We need Regulatory Data Translators who have the technical and legal courage to look past the 16-week delta and ask: “Is this a durable breakthrough, or just a well-timed data snapshot?”

The BIMO & Manufacturing Landmine Even with “successful” data, the recent FDA snub of the Elevar/Hengrui combo highlights the critical gap between clinical success and regulatory readiness. Manufacturing deficiencies and BIMO (Bioresearch Monitoring) inspection failures are the “silent killers” of promising NDAs.

True governance isn’t just about validating an algorithm; itโ€™s about auditing the science and the infrastructure before the FDA does.

Pharyngeal Electrical Stimulation (PES) for Neurogenic Dysphagia: An Overview


Pharyngeal Electrical Stimulation (PES) for Neurogenic Dysphagia: An Overview

Introduction to Neurogenic Dysphagia and the Need for Restorative Therapy

Neurogenic dysphagia (ND) is a swallowing impairment resulting from neurological damage, most commonly caused by stroke, multiple sclerosis (MS), traumatic brain injury, or neurodegenerative diseases.1 ND is associated with severe complications, including malnutrition, dehydration, and aspiration pneumonia, which significantly increases morbidity and mortality.2

Traditionally, dysphagia management has relied heavily on compensatory strategies (e.g., thickened liquids, postural changes) or enteral feeding (feeding tubes).3 While necessary for immediate safety, these approaches do not treat the underlying neurological deficit. Consequently, there has been a growing demand for restorative therapies that target neuroplasticity to recover swallowing function. Pharyngeal Electrical Stimulation (PES) has emerged as a leading technique in this restorative domain.

The PES Procedure

As described in the initial text, PES is carried out via location-specific intraluminal catheters. These catheters are designed with integrated ring electrodes at the distal tip.

  • Placement: The catheter is introduced transnasally by a clinician until the electrodes are positioned directly within the pharynx. Accurate positioning is crucial to ensure stimulation targets the appropriate sensory receptors in the pharyngeal mucosa.

  • Stimulation Parameters: Once positioned, the catheter delivers defined electrical pulses. The intensity is usually titrated to the patient’s individual sensory threshold (the point at which they first feel a tingling sensation) and then set at an optimal therapeutic level, which is typically strong but not painful.4
  • Treatment Regimen: A common protocol involves daily sessions lasting approximately 10 minutes for a period of 3 to 5 consecutive days, often performed at the bedside in acute or rehabilitation settings.

Mechanism of Action: Driving Neuroplasticity

The core premise of PES is that augmenting sensory input from the periphery can drive central nervous system reorganization.5 Your text correctly identifies that PES likely works by “increasing corticobulbar excitability and inducing cortical reorganization of swallowing motor cortex.”

To elaborate on this physiological process:

  1. Sensory Bombardment: The pharynx is richly innervated with sensory receptors crucial for triggering the swallow reflex.6 PES provides intense, controlled afferent (sensory) stimulation to these nerves (primarily the glossopharyngeal and vagus nerves).7
  2. Corticobulbar Pathway Activation: These sensory signals travel up to the brainstem swallowing centers and further to the sensorimotor cortex. In patients with neurological damage, the cortical representation of swallowing is often suppressed or damaged.8
  3. Cortical Reorganization (Neuroplasticity): The repetitive sensory input from PES acts to increase the excitability of the corresponding motor cortex areas.9 Over time, this can “reawaken” dormant neural pathways or recruit adjacent, undamaged cortical areas to take over the swallowing functionโ€”a process known as adaptive cortical reorganization.

Clinical Evidence and Target Populations

PES is transitioning from an experimental therapy to clinical practice due to an increasingly promising evidence base.10

  • Stroke: The strongest evidence for PES lies in post-stroke dysphagia. Several randomized controlled trials have demonstrated that PES can accelerate swallowing recovery, reduce the severity of aspiration, and lead to earlier decannulation (removal) of tracheostomy tubes and weaning from feeding tubes compared to standard care.11
  • Multiple Sclerosis (MS): As noted, PES shows promise in MS patients. Dysphagia in MS is often related to brainstem lesions.12 PES appears effective in enhancing residual sensory pathways in these patients, improving swallow coordination and safety.13
  • Other Applications: Research is ongoing into the use of PES for dysphagia related to Parkinsonโ€™s disease and critical illness polyneuropathy following prolonged ICU stays.14

Summary

Pharyngeal Electrical Stimulation represents a significant shift in dysphagia management, moving from purely compensatory measures to active neurological rehabilitation. By directly stimulating the pharynx to harness the brain’s innate ability to reorganize, PES offers a restorative therapeutic option for improving swallowing performance in complex neurogenic conditions like stroke and multiple sclerosis.15ย 

What the Meta-Analysis Shows (The Positive Findings):

  1. Statistically Significant Improvement in Swallowing Function:ย The overall analysis found that the PES group had better swallowing function scores than the control group (SMD = -0.20, P=0.02). The specificย Dysphagia Severity Rating Scale (DSRS)ย also showed a significant difference (P=0.05). This means PES has a measurable, positive effect on improving theย severityย of dysphagia.

  2. Clinically Meaningful Outcome: Nasogastric Tube Withdrawal:ย This is the strongest piece of evidence for a tangible, life-changing benefit. The PES group had aย nearly 3 times higher rateย of having their feeding tubes removed (RR = 2.88, P=0.02). For a patient, this means transitioning from tube feeding back to oral intakeโ€”a massive improvement in quality of life, autonomy, and a reduced risk of tube-related complications.

The Limitations and “Lacking Evidence” (The Reality Check):

  1. The Effect Size is Modest:ย The Standardized Mean Difference (SMD) of -0.20 for overall swallowing function is considered aย small effect size. This suggests that while there is a real benefit, the average improvement across all patients is not dramatic. It indicates PES is an effectiveย adjuvant therapy, not a standalone cure.

  2. What It Didย Notย Clearly Prove (Based on This Review):

    • Reduction in Aspiration:ย The review states evidence for reducing aspiration is lacking. Theย Penetration-Aspiration Scale (PAS)ย is mentioned as an outcome in some studies, but no pooled significant result is reported. This is critical because preventing pneumonia is a primary goal of dysphagia therapy.

    • Shorter Hospital Stays (LOS):ย No significant difference was found in length of stay. This suggests that while PES improves function, it may not accelerate the overall complex discharge process for stroke patients.

    • Generalizability to All Patients:ย The included studies (2010-2018) likely had specific inclusion/exclusion criteria. PES may work best for patients with a certain type or severity of dysphagia (e.g., pharyngeal phase impairment) and not for those with very severe or complete loss of swallow function.

Conclusion: Making Swallowing Possible vs. Meaningfully Helping

  • For some patients, PES may indeed “make swallowing possible.”ย The high rate of nasogastric tube withdrawal strongly implies that a number of patients regainedย functional, safe enough oral intakeย to eliminate the need for tube feeding. This is a transformative outcome.

  • For the broader population, PES is a valuable tool that “meaningfully helps.”ย It provides a statistically significant boost to swallowing rehabilitation, contributing to measurable functional gains. It is not a passive “fix”; it is anย assistive technologyย that enhances neuroplasticity and should be integrated into a comprehensive dysphagia therapy program (including compensatory strategies, strengthening exercises, etc.).

In summary, your meta-analysis supports that PES is an evidence-based, effective intervention for post-stroke dysphagia with a particularly strong impact on achieving oral feeding independence (tube withdrawal). Its effect is real and clinically important, but its role is that of a potent facilitator within a broader rehabilitation context, rather than a universal “on-switch” for swallowing. The call for further studies on aspiration and functional oral intake is warranted to better define its optimal use and patient selection.

Neuroplasticity: A Strategic Framework for Cognitive Optimization and Adaptive Performance

Neuroplasticity: A Strategic Framework for Cognitive Optimization and Adaptive Performance

For the professional committed to continuous improvement and strategic growth, understanding the mechanistic principles of neuroplasticity is not merely academicโ€”itโ€™s a critical operational framework. Moving beyond the simplistic metaphor of “rewiring,” a rigorous comprehension of the brain’s adaptive capacities provides a blueprint for cultivating the cognitive agility, resilience, and innovative potential demanded in high-performance environments.

Deconstructing the Mechanism: Beyond Metaphor

Neuroplasticity is the umbrella term for the brain’s enduring structural and functional adaptability in response to experience. This is not a singular process but a symphony of cellular and molecular events:

  • Synaptic Plasticity:ย The foundational Hebbian principleโ€””neurons that fire together, wire together”โ€”is operationalized throughย Long-Term Potentiation (LTP)ย andย Long-Term Depression (LTD). These are activity-dependent strengthening or weakening of synaptic connections, governed by NMDA receptor activation, calcium influx, and downstream signaling cascades. This is the primary substrate for learning and memory consolidation.

  • Structural Plasticity:ย This involves physical changes, includingย dendritic spine remodeling,ย axonal sprouting, andย adult neurogenesisย (primarily in the hippocampus). These changes are driven by neurotrophic factors likeย Brain-Derived Neurotrophic Factor (BDNF), which acts as a key modulator of synaptic efficacy and neuronal survival.

  • Functional Reorganization:ย Following injury or during skill acquisition, cortical maps can shift. This is evidenced by seminal fMRI studies, such as those on violinists exhibiting expanded somatosensory cortex representation of their fingering hand.

The strategic insight is that these processes are competitive and resource-intensive. The brain operates on a “use it or lose it” principle, where unstimulated pathways are pruned via synaptic elimination.ย Directed neuroplasticity, therefore, requires conscious intervention to guide these biological mechanisms toward desired cognitive outcomes.

A Strategic Toolkit for Directed Neuroplasticity

For the professional, this translates into a deliberate regimen for cognitive capital investment.

1. Targeted Cognitive Challenge & Enriched Environments

The brain adapts to specific demand. Passive exposure is insufficient. The key isย deliberate practiceย within theย zone of proximal development, which induces metabolic stress (increased cerebral blood flow, glucose/oxygen utilization) and activates gene expression programs related to synaptic growth. This could be:

  • Mastering a complex new software language (e.g., Python for a non-engineer).

  • Engaging in strategic games requiring working memory and probabilistic reasoning (e.g., chess, Go).

  • Learning a technical domain outside one’s core expertise.

2. Leveraging the Neurochemistry of Focus

Diffuse attention (e.g., constant context-switching) promotes weak, transient connections.ย Sustained, focused attentionโ€”mediated by prefrontal cortex networks and neuromodulators like norepinephrine and acetylcholineโ€”is the trigger for robust LTP. Techniques include:

  • Deep Work Blocks:ย 90-120 minute sessions of uninterrupted, high-cognitive-load tasks.

  • Mindfulness-Based Stress Reduction (MBSR):ย Proven to increase gray matter density in the prefrontal cortex and hippocampus while reducing amygdala volume, enhancing emotional regulation and meta-cognition.

3. Utilizing Exercise as a Cognitive Catalyst

Aerobic exercise is a potent upregulator ofย BDNFย and vascular endothelial growth factor (VEGF). It enhances hippocampal neurogenesis, improves cerebral perfusion, and optimizes the brain’s metabolic environment. This isn’t about general wellness; it’s aboutย priming the neurobiological substrate for learning. A strategic regimen of 150 minutes of moderate-intensity exercise per week is a non-negotiable cognitive investment.

4. Strategic Consolidation: The Role of Sleep Architecture

Plastic changes are consolidated duringย slow-wave sleep (SWS)ย andย REM sleep. SWS is critical for synaptic down-selection and memory consolidation, while REM facilitates associative memory networks.ย Sleep deprivation directly impairs BDNF signaling and hippocampal function.ย Prioritizing 7-9 hours of quality sleep is a performance imperative, not a luxury.

5. The Feedback Loop of Mindset

Carol Dweck’sย growth mindsetย finds its neural correlate. Believing in malleable intelligence reduces threat reactivity (amygdala) and increases engagement of error-monitoring and corrective circuits (anterior cingulate cortex). This creates a positive feedback loop: challenge -> effort -> adaptive neural change -> improved performance -> reinforced growth mindset.

Implications for Talent and Leadership Development

A professional who actively applies these principles demonstrates a quantifiable edge:

  • Rapid Skill Acquisition:ย The ability to deconstruct and internalize complex new systems efficiently.

  • Enhanced Problem-Solving:ย A brain trained in plasticity can more readily form novel connections between disparate concepts.

  • Resilience Under Pressure:ย The capacity to adapt functional networks in response to failure or changing market conditions.

  • Strategic Metacognition:ย The awareness to audit and direct one’s own cognitive development strategically.

Conclusion: The Plastic Brain as a Competitive Advantage

In an economy defined by volatility and disruption, the most valuable asset is an adaptable mind. Neuroplasticity provides the empirical foundation for a lifelong strategy of cognitive capital appreciation. It transforms personal development from a vague aspiration into a series of deliberate, biologically-informed interventions. The individual who masters the science of their own brain’s potential doesn’t just adapt to the futureโ€”they actively construct it.


Beyond the Nomogram: Achieving Pharmacokinetic Targets to Combat Superbugs

Antimicrobial resistance (AMR) is perhaps the most pressing global health crisis of our time. The pipeline for new antibiotics is slow, meaning that our most powerful tool in the fight against “superbugs” is optimizing the use of the drugs we already possess. The traditional approach to antibiotic dosingโ€”relying on standard, one-size-fits-all nomogramsโ€”is increasingly inadequate because the clinical environment is highly variable. Critically ill patients, those with obesity, or individuals with impaired organ function handle medications vastly differently. This variability leads to two dangerous outcomes: underdosing, which encourages resistance development and treatment failure; and overdosing, which causes unnecessary toxicity. This is where Model-Informed Precision Dosing (MIPD) emerges as a critical, life-saving strategy.

The core principle behind MIPD is moving from a simple dosage (e.g., 1g every 12 hours) to an individualized Pharmacokinetic/Pharmacodynamic (PK/PD) target. For most antibiotics, the key to success is ensuring the patient’s drug exposure stays above a certain threshold relative to the bacteria’s susceptibility. For concentration-dependent killers like aminoglycosides, this might be achieving a high peak concentration (Cmax). But for time-dependent drugs like vancomycin and beta-lactams, the goal is often the Area Under the Curve to Minimum Inhibitory Concentration ratio (AUC24/MIC). This ratio represents the total drug exposure over 24 hours relative to the concentration required to stop bacterial growth. Achieving this precise target requires more than a standard doseโ€”it demands a predictive model.

MIPD makes this personalized dosing possible by integrating advanced population PK models with real-time patient data. A population PK model is a mathematical framework built from thousands of patient experiences that describes how a drug is typically absorbed, distributed, metabolized, and excreted (ADME). This model accounts for common patient covariates that significantly alter drug handling, such as age, body weight, renal clearance (measured by creatinine), and disease state (e.g., sepsis). When a clinician inputs a patient’s demographics and a recent drug concentration (via Therapeutic Drug Monitoring, or TDM), the population model uses Bayesian forecasting to calculate that specific patient’s unique PK parameters.

This ability to rapidly calculate individualized PK parameters is transformative, especially in the Critical Care setting. In sepsis or burn patients, rapid fluid shifts, high fever, and inflammation can lead to augmented renal clearanceโ€”a condition where the kidneys remove antibiotics far faster than normal. Standard dosing in these patients inevitably leads to sub-therapeutic concentrations and potential treatment failure. Conversely, in elderly patients with acute kidney injury, the standard dose could quickly become toxic. MIPD allows the care team to see this real-time risk, quickly adjust the dose or frequency, and predict the next concentration to ensure the patient is on track to hit the $AUC_{24}/MIC$ target within the first 24 hours of therapyโ€”a crucial predictor of clinical success.

The shift toward MIPD also represents a technological leap in how we use TDM. Traditional TDM required calculating a new dose using manual, often inaccurate, equations or simplified nomograms after a drug level returned. Modern MIPD is executed through sophisticated, commercially available software programs that run the Bayesian forecasting model almost instantaneously. This integration of pharmacometrics into the clinical workflow transforms TDM from a reactive check into a proactive dose-optimization tool. By reducing the time to achieve the optimal PK/PD target, MIPD not only improves individual patient outcomes but also applies selective pressure to the bacterial population, helping to slow the emergence and spread of antimicrobial resistance.

In summary, Model-Informed Precision Dosing is the necessary future of antimicrobial stewardship. It replaces generic guesswork with personalized mathematics, using powerful PK/PD models to ensure every patient receives the exact drug exposure needed to sterilize the infection. For challenging drugs like vancomycin, aminoglycosides, and beta-lactams, MIPD is not just an optimizationโ€”it is a mandatory standard of care that preserves the efficacy of our existing antibiotic arsenal. Clinicians must advocate for the implementation of these tools to ensure we stay ahead in the perpetual race against the evolution of superbugs.

COVID-19 Treatment Strategies: Dec 2025 update

Should I Get a COVID-19 Vaccine in December 2025 or January 2026?

As we move through the winter of 2025-2026, the question of whether to get a COVID-19 vaccine is highly relevant, especially as respiratory viruses typically peak during this time. The short answer, based on the latest health authority guidance, is that the updated 2025-2026 vaccine is widely recommended and remains your best defense against severe illness, hospitalization, and death from the virus. Since the peak of the respiratory seasonโ€”when local COVID-19 transmission levels are highestโ€”often spans December through February, getting the updated vaccine now, if you haven’t already, offers critical, timely protection.

Unlike the initial vaccine rollout, current guidance emphasizes individual-based decision-making for most people aged 6 months to 64 years. This means the decision should be a discussion between you and your healthcare provider, taking into account your personal risk factors. That said, the consensus among experts is clear: protection from previous vaccination and natural infection diminishes over time. The 2025-2026 vaccines are specifically updated to target the currently circulating JN.1-lineage of the Omicron variant, providing better immune matching and more robust protection against the strains most likely to cause illness this winter.

For several key groups, the recommendation to get the 2025-2026 vaccine is particularly strong. This includes adults aged 65 and older, as well as people of any age who have underlying health conditions that increase their risk for severe COVID-19 (such as chronic lung disease, heart disease, diabetes, or a weakened immune system). Individuals who are pregnant or those who have never received a COVID-19 vaccine also fall into this high-priority category. If you are in one of these groups, and you have not received the updated vaccine, December or January is an excellent time to get it to maximize protection during the high-risk winter months.

A common question is what to do if you recently had COVID-19. Health experts generally advise that you may delay getting a vaccine for about three months after your symptoms started or after testing positive without symptoms. This delay allows you to benefit from the temporary immunity boost provided by the infection while ensuring the vaccine dose is given when it can provide the most durable, long-term protection. If you have any concerns about timing, especially if you also plan to get the flu or RSV vaccine, consult your doctor or pharmacist.

Ultimately, whether you get your vaccine in December 2025 or January 2026, the important takeaway is to ensure you receive the 2025-2026 updated formulation. It is designed to offer the best possible shield against the latest viral threats this season. By getting vaccinated, you protect not only your own health but also the health of vulnerable people in your community.


To get the best advice for your personal situation, please consult your primary care physician or a licensed pharmacist.

COVID-19 Treatment Strategies

  • As of 2023, a few small-molecule antiviral drugs (nirmatrelvir-ritonavir, remdesivir, and molnupiravir) and 11 monoclonal antibodies have been marketed for the treatment of COVID-19, mostly requiring administration within 10 days of symptom onset.
  • Hospitalized patients with severe or critical COVID-19 may benefit from treatment with previously approved immunomodulatory drugs, including glucocorticoids such as dexamethasone, cytokine antagonists such as Genentechโ€™s tocilizumab, and Janus kinase inhibitors such as Lillyโ€™s baricitinib.
  • Repurposing RNA polymerase nucleotide drugs, such as Gileadโ€™s remdesivir and Merckโ€™s molnupiravir, to inhibit viral RNA synthesis should have a relatively high probability of success, but it remains a trial-and-error endeavour to identify nucleotide/nucleoside analogs that escape the SARS-CoV-2 proofreading mechanism.
  • Repurposing DNA polymerase inhibitors, such as Gileadโ€™s tenofovir, to inhibit the RNA synthesis of SARS-CoV-2 is likely to fail due to their different mechanisms of action.
  • HIV protease inhibitors, such as lopinavir, should not be repurposed for SARS-CoV-2 treatment due to the lack of similarity between the drug-binding pockets in HIV and SARS-CoV-2 proteases.
  • Except for nucleoside/nucleotide inhibitors such as tenofovir, ribavirin, and lamivudine, other virus-targeted inhibitors have not been approved by the FDA to treat more than one infectious disease. They are not good repurposing candidates because their chemical structures are often designed to target a particular drug-binding pocket with high selectivity, and thus they are unlikely to have a similar level of potency against an unrelated target.
  • Cationic amphiphilic drugs (such as hydroxychloroquine, azithromycin, and amiodarone) that induce phospholipidosis should not be repurposed, because cellular phospholipidosis is often misinterpreted as antiviral efficacy.
  • A new one-step immunoassays has been developed for rapid and sensitive detection of SARS-CoV-2 by using a single-chain variable fragment (scFv) fused to alkaline phosphatase (AP) or NanoLuc (NLuc) luciferase. First, a high-affinity scFv antibody specific to the SARS-CoV-2 nucleocapsid (N) protein was screened from hybridoma cells-derived and phage-displayed library. Next, prokaryotic expression of the scFv-AP and scFv-NLuc fusion proteins were induced, leading to excellent antibody binding properties and enzyme catalytic activities.
  • Upregulation of interleukin-6 (IL-6) has been associated with worse prognosis in COVID-19 patients. Janssen conducted a phase 2 randomized control trial to evaluate the efficacy and safety of free IL-6 sequestration by the monoclonal antibody sirukumab in severe and critical COVID-19 patients. In critical COVID-19 patients who received sirukumab, there was no statistically significant difference in time to sustained clinical improvement versus placebo despite objective sequestration of circulating IL-6, questioning IL-6 as a key therapeutic target in COVID-19.

From Dec. 1, 2021

The CDC confirmed today the first case of the Omicron variant, which is officially known as B1.1.529,ย  in the United States.ย  The most concerning aspect of this new variant is the number of mutations associated with it.ย  Viruses are not living organisms; they require a host to continue or survive. The more hosts that viruses can find, the more likely they are to mutate further and potentially become more harmful to the hosts. Viruses cannot replicate on their own.ย  Instead they capture or “hijack” the reproductive mechanism in the host cell, redirect it to copy the genetic code of the virus, and seal it in a packet called a capsid. In a single human being, there can be a billion or even a trillion copies of the SARS-CoV-2 virus. Most of the time, these mutations or mistakes involve different amino acid sequences that may give rise to different proteins but do not enhance the ability of the virus to infect or replicate any better than the original copy. Occasionally, a mutation will increase infectivity and may, or may not, code for a new protein that the immune system fails to recognize.

The spike protein on SARS-CoV-2 interacts specifically with the ACE2 receptor, which is found on the surface of our cells mainly in the GI tract, the respiratory tract, and our vasculature. When the newย  viral particles are created, they may have slightly different proteins either inside or outside the viral particle.ย  Of particular interest, the mutation may exist on the outer tip of the spike protein, which is called the receptor binding domain (RBD).ย  Our immune system recognizes the SARS-CoV-2 based on the RBD. Thus any mutation that changes the proteins in areas that make it easier for the virus to bind to our cells’ receptors or evade detection by the immune system will be advantageous to virus survival.

Let’s compare Omicron to two prior variants:ย  Alpha and Delta.ย  As to the virus particle itself, Alpha had 23 mutations, Delta had 17 mutations, and Omicron has 50 mutations.ย  As to the spike protein, Alpha had 9 mutations, Delta had 7 mutations, and Omicron has 32 mutations. As to the RBD, Alpha had 1 mutation, Delta had 2 mutations, and Omicron has 10 mutations.ย  The number and variety of mutations associated with the Omicron variant deserves serious concern.

Variants

Alpha Delta Omicron

Virus

23 mutations 17ย mutations 50ย mutations
Spike 9 mutations 7 mutations

32ย mutations

RBD 1 mutation 2 mutations

10 mutations

Scientists are now focused on three questions: (1) what is the transmissibility of the Omicron variant?, (2) how well does it evade our current COVID-19 vaccines?, and (3) is there a change in the virulence (the variant is more deadly)?

 

From July 24, 2021

  • The Delta variant (B.1.617.2) has proven to be more contagious than the original SARS-CoV-2 (R0 = 3.5โ€“4.5 vs R0 ~ 2.5) perhaps through better binding or better evasion of the immune system. (The spike protein of SARS-CoV-2 is coated with sugar molecules, or glycans, that help it evade the immune system.) The REACT-1 round 12 report (Imperial College London) found the Delta variant prevalence in those aged 5โ€“49 was 2.5 times higher at 0.20% (0.16%, 0.26%) compared with those aged 50 years and above at 0.08% (0.06%, 0.11%). While people over age 50 may have higher vaccination rates, the Delta variant may pose a higher risk of infection for younger-aged individuals. As to hospitalization, The Lancet published correspondence (June 26, 2021) on a study in Scotland that the Delta variant had a 1.85 times higher risk of getting the person infected admitted to the hospital with severe COVID-19 [hazard ratio 1.85 (95% CI 1.39โ€“2.47)].ย  The Scottish study usedย Reverse Transcription Polymerase Chain Reaction (RT-PCR) tests and a Cox regression analysis, which adjusts for age, sex, economic status/deprivation, temporal trend, and comorbidities.
  • As of July 2021, the Pfizer-BioNTech vaccine was shown to be effective against the Delta variant symptomatic infection at 88% (UK study), 87% (Canadian study), 64% (Israeli study), 79% (Scottish study), and effective against the Delta variant resulting in hospitalization at 96% (UK study) and 98% (Israeli study). The data for the Moderna vaccine are more limited and show the vaccine is 72% effective against symptomatic infection and 96% effective against hospitalization for the Delta variant after just the first dose of the two-dose vaccine. The Oxford-Astrazeneca vaccine was found to be effective against the Delta variant at 60% (UK study), 67% (Canadian study for single dose), 60% (Scottish study) for symptomatic infection and 93% (UK study), 88% (Canadian study) effective against Delta variant hospitalization. For the J&J vaccine, real-world evidence on effectiveness against the Delta variant is not yet available; however, J&Jโ€™s internal lab study showed it was highly effective against the South African variant, which was most prevalent at the time, and that the antibody response to the Delta variant is even better: a very good antibody response to the Delta variant based on lab testing.

From May 27, 2021

For early-onset COVID-19 cases (positive COVID-19 test and at-risk for progression of the disease but not experiencing symptoms requiring hospital-ization): “The FDA has halted the distribution of Lillyโ€™s combination of bamlanivimab and etesevimab in Arizona, California, Florida, Indiana, Oregon and Washingtonโ€“โ€“all states where coronavirus variants from Brazil and South Africa account for more than 10% of those with the disease. The antibody combo had previously been paused in Illinois and Massachusetts.

Providers in those states should use Regeneronโ€™s antibody treatment of casirivimab and imdevimab, as per the FDA. Lab studies have shown that option is more effective against the Brazilian (P.1) and South African (B.1.351) strains, according to the agency.” [https://www.fiercepharma.com/pharma/fda-halts-use-lilly-covid-19-antibody-treatment-6-states-where-variants-are-prevalent]

Timing is important: MABS are very good at stopping the virus outside the cells. Once the SARS-CoV-2 has infected the cells, antibodies are not able to neutralize the virus. The patient then needs cytotoxic T-cells.

Two randomized clinical trials of Vitamin D, one from India (SHADE study) and one from Spain (calcifediol study), have shown that Vitamin D supplementation definitely benefitted patients with COVID-19. Emerging evidence shows Vitamin D combined with either or both Vitamin K2 and Magnesium potentiates the benefits of Vitamin D. Source for K2 synergy: https://pubmed.ncbi.nlm.nih.gov/29138634/

QUERCETIN in combination with vitamins C and D, may exert a synergistic antiviral action. Source: https://journals.sagepub.com/doi/full/10.1177/1934578X20976293

N-ACETYL-CYSTEINE (NAC) (600 mg) has known antiviral and liver protective properties. One argument for use with COVID-19 is https://pubmed.ncbi.nlm.nih.gov/32780893/ and another https://pubmed.ncbi.nlm.nih.gov/24968347/ and https://pubmed.ncbi.nlm.nih.gov/9230243/

SLEEP (7 – 9 hours): antibody and immune response after (flu) vaccination is improved if the patient has had a good night’s sleep, particularly the hours of sleep before midnight (slow wave sleep). Optimal T-cell production for disease prevention also requires optimal sleep. Melatonin may help patients get to sleep and has anti-viral properties. https://pubmed.ncbi.nlm.nih.gov/32347747/ https://pubmed.ncbi.nlm.nih.gov/32768490/

At the early stages of COVID-19 infection, the innate immune system is responsible for attacking the virus (primarily using monocytes & natural killer cells) through production of Interferon (IFN). SARS-CoV-2 delays the body’s IFN response. Patients with severe disease had less type I IFN activity in their blood compared to patients with mild to moderate disease. (The innate immune system diminishes with aging.) Any method to enhance the innate immune response in the early course of the disease could limit progression of COVID-19. Sauna baths, hot water baths, and other sources of human hyperthermia can induce a tenfold increase IFN-gamma synthesis. https://pubmed.ncbi.nlm.nih.gov/3132509/ These results suggest that raising the core body temperature akin to a mild fever may stimulate the innate immune system (particularly if followed by a cold shower or rapid cooling) and thereby attenuate COVID-19.

From APRIL 2020

“To be clear, SARS-CoV-2 is not the flu. It causes a disease with different symptoms, spreads and kills more readily, and belongs to a completely different family of viruses. This family, the coronaviruses, includes just six other members that infect humans. Four of themโ€”OC43, HKU1, NL63, and 229Eโ€”have been gently annoying humans for more than a century, causing a third of common colds. The other twoโ€”MERS and SARS (or โ€œSARS-classic,โ€ as some virologists have started calling it)โ€”both cause far more severe disease. Why was this seventh coronavirus the one to go pandemic? Suddenly, what we do know about coronaviruses becomes a matter of international concern.” Why the Coronavirus Has Been So Successful, The Atlantic

This article was inspired by the work of Jon Barron shown here: https://www.jonbarron.org/colds-flus-infectious-diseases/using-anti-pathogens. To combat the coronavirus, I have stocked my medicine cabinet with the following anti-viral pathogen natural products. In addition to providing the names and doses of the products, after each one, I provide the ten most recent citations from PubMed.gov pertaining to that substance and viruses.

  1. AHCC (Active Hexose-Correlated Compound) – 500 mg, taken on an empty stomach up to four capsules per day at outset of symptoms
  2. Olive Leaf Extract (Olea europaea) (standardized to minimum 20% oleuropein) – 500 mg, taken with food once or twice per day.
  3. Oil of Oregano (Origanum vulgare) (leaf) (10:1 extract) – 150 mg, taken up to four gelcaps per day with water
  4. Star Anise Oil – 1 fluid oz, blended and diluted with extra virgin olive oil or extra virgin coconut oil
  5. Minced Garlic — 1 tbsp added to main meal

 

AHCC (Active Hexose-Correlated Compound)

“Mushrooms have been used for various health conditions for many years by traditional medicines practiced in different regions of the world although the exact effects of mushroom extracts on the immune system are not fully understood. AHCCยฎ is a standardized extract of cultured shiitake or Lentinula edodes mycelia (ECLM) which contains a mixture of nutrients including oligosaccharides, amino acids, and minerals obtained through liquid culture. AHCCยฎ is reported to modulate the numbers and functions of immune cells including natural killer (NK) and T cells which play important roles in host defense, suggesting the possible implication of its supplementation in defending the host against infections and malignancies via modulating the immune system. Here, we review in vivo and in vitro effects of AHCCยฎ on NK and T cells of humans and animals in health and disease, providing a platform for the better understanding of immune-mediated mechanisms and clinical implications of AHCCยฎ.” Shin MS, Park HJ, Maeda T, Nishioka H, Fujii H, Kang I.

The outbreak of SARS-CoV-2 disease (COVID-19) is currently, March 2020, affecting more than 100000 people worldwide and, according to the WHO (World Health Organization), a pandemic is shortly expected. The virus infects the lower respiratory tract and causes severe pneumonia and mortality in approximately 10% and 3-5%, respectively, of cases, mainly among the elderly and/or people affected by other diseases. AHCC is an ฮฑ-glucan-based standardized mushroom extract that has been extensively investigated as an immunostimulant both in animals and/or in humans affected by West Nile virus, influenza virus, avian influenza virus, hepatitis C virus, papillomavirus, herpes virus, hepatitis B virus and HIV by promoting a regulated and protective immune response. Although the efficacy of AHCC has not yet been specifically evaluated with respect to SARS-CoV-2 disease, its action in promoting a protective response to a wide range of viral infections, and the current absence of effective vaccines, could support its use in the prevention of diseases provoked by human pathogenic coronavirus, including COVID-19.

OLIVE LEAF EXTRACT

“The olive tree (Olea europaea) is native to the Mediterranean region. Olive leaf extract has a long history of use against illnesses in which microorganisms play a major role. In more recent years, studies of olive leaf extracts (containing oleuropein, calcium elenolate, and/or hydroxytyrosol) were effective in eliminating a very broad range of organisms, including bacteria, viruses, parasites, yeast, mold, and fungi.25 Pio Maria Furneri, Anna Piperno, Antonella Sajia, and Giuseppe. โ€œAntimycoplasmal Activity of Hydroxytyrosol, Antimicrob Agents.โ€ Chemother. 2004 December; 48(12): 4892โ€“4894. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC529223/ , 26 Harold E. Renis. โ€œInactivation of Myxoviruses by Calcium Elenolate.โ€ Antimicrobial Agents and Chemotherapy Aug. 1975, p. 194-199. http://aac.asm.org/cgi/reprint/8/2/194.pdf In addition, Olive leaf has demonstrated antiviral activity against both HIV infection and replication,27 Lee-Huang S1, Zhang L, Huang PL, Chang YT, Huang PL. โ€œAnti-HIV activity of olive leaf extract (OLE) and modulation of host cell gene expression by HIV-1 infection and OLE treatment.โ€ Biochem Biophys Res Commun. 2003 Aug 8;307(4):1029-37. http://www.ncbi.nlm.nih.gov/pubmed/12878215 primarily by blocking the entry of the virus into host cells in the bodyโ€™s immune system.28 Bao J1, Zhang DW, Zhang JZ, Huang PL, Huang PL, Lee-Huang S. โ€œComputational study of bindings of olive leaf extract (OLE) to HIV-1 fusion protein gp41.โ€ FEBS Lett. 2007 Jun 12;581(14):2737-42. http://www.ncbi.nlm.nih.gov/pubmed/17537437

Studies have also shown that oleuropein exhibits a significant antiviral activity against respiratory syncytial virus and para-influenza type 3 virus.29 Ma SC, He ZD, Deng XL, But PP, et al. โ€œIn vitro evaluation of secoiridoid glucosides from the fruits of Ligustrum lucidum as antiviral agents.โ€ Chem Pharm Bull. 2001;49:1471โ€“1473. http://www.jstage.jst.go.jp/article/cpb/49/11/49_11_1471/_pdf In addition, it has been found to be effective against viral hemorrhagic septicemia rhabdovirus, a highly deadly and infectious virus that afflicts over 50 species of both freshwater and marine water fish. 30 Micol V, Caturla N, Perenz-Fons L, Mas L, Perez L, Estepa A. โ€œThe olive leaf extract exhibits antiviral activity against viral haemorrhagic septicaemia rhabdovirus (VHSV)โ€ Antivir Res. 2005;66:129โ€“136. http://www.ncbi.nlm.nih.gov/pubmed/15869811 There are studies that demonstrate that olive leaf extracts augment the activity of the HIV-RT inhibitor 3TC. In fact, cell-to-cell transmission of HIV was inhibited in a dose-dependent manner, and replication was inhibited in an in vitro experiment.31 Lee-Huang S, Zhang L, Chang YY, Huang PL. โ€œAnti-HIV activity of olive leaf extract (OLE) and modulation of host cell gene expression by HIV-1 infection and OLE treatment.โ€ Biochem Biophys Res Commun. 2003;307:1029โ€“1037. http://www.ncbi.nlm.nih.gov/pubmed/12878215 One of the suspected targets for olive leaf extract action is the HIV-1 gp41 (surface glycoprotein subunit), which is responsible for HIV entry into normal cells. In order to establish HIV protein targets of olive leaf extract and its inhibitory action at the molecular level, researchers reported a joint theoretical and experimental effort has been carried out to help achieve this goal.32 Lee-Huang S, Huang PL, Zhang D, Lee JW, Bao J, et al. โ€œDiscovery of small-molecule HIV-1 fusion and integrase inhibitors oleuropein and Hydroxytyrosol: Part I.โ€ Integrase Inhibition Biochem Biophys Res Commun. 2007;354:872โ€“878. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2790717/

Screening for antiviral activities of isolated compounds from essential oils

Astani A, et al. Evid Based Complement Alternat Med 2011.
Essential oil of star anise as well as phenylpropanoids and sesquiterpenes, for example, trans-anethole, eugenol, ฮฒ-eudesmol, farnesol, ฮฒ-caryophyllene and ฮฒ-caryophyllene oxide, which are present in many essential oils, were examined for their antiviral activity against herpes simplex virus type 1 (HSV-1) in vitro. Antiviral activity was analyzed by plaque reduction assays and mode of antiviral action was determined by addition of the drugs to uninfected cells, to the virus prior to infection or to herpesvirus-infected cells. Star anise oil reduced viral infectivity by >99%, phenylpropanoids inhibited HSV infectivity by about 60-80% and sesquiterpenes suppressed herpes virus infection by 40-98%. Both, star anise essential oil and all isolated compounds exhibited anti-HSV-1 activity by direct inactivation of free virus particles in viral suspension assays. All tested drugs interacted in a dose-dependent manner with herpesvirus particles, thereby inactivating viral infectivity. Star anise oil, rich in trans-anethole, revealed a high selectivity index of 160 against HSV, whereas among the isolated compounds only ฮฒ-caryophyllene displayed a high selectivity index of 140. The presence of ฮฒ-caryophyllene in many essential oils might contribute strongly to their antiviral ability. These results indicate that phenylpropanoids and sesquiterpenes present in essential oils contribute to their antiviral activity against HSV.
