00 · Foundational systems-medicine thesis
Modern clinical practice must name diseases accurately, yet a diagnosis often captures the endpoint of a lengthy biological sequence rather than the first cause. This paper proposes an organizing model for chronic illnes…
01 · Cerebrovascular systems and sterol transport
An ischemic stroke is a neurological emergency, yet the vessel occlusion may be the end of a process that began years earlier in the intestine, liver, heart, vascular wall or coagulation system. This paper presents a mul…
01 · Cerebrovascular systems and sterol transport
Sitosterolemia offers a rare but informative demonstration that handling of absorbed sterols—not merely the amount consumed—can alter cardiovascular biology. The disorder results from deficient ABCG5/ABCG8 transport and…
01 · Cerebrovascular systems and sterol transport
Bile acids are not confined to digestion. They signal through nuclear and cell-surface receptors and influence inflammatory and vascular biology. This paper examines a narrow frontier possibility: altered bile-acid compo…
01 · Cerebrovascular systems and sterol transport
Atherogenesis is often discussed in terms of cholesterol alone. Yet hepatointestinal bile-acid receptors regulate lipid synthesis, glucose homeostasis and inflammatory signaling. This paper proposes a conditional model i…
01 · Cerebrovascular systems and sterol transport
Some bile-acid species and derivatives are being studied for cellular stress responses, mitochondrial function and inflammation in neural injury. This paper examines the provocative possibility that the same enterohepati…
01 · Cerebrovascular systems and sterol transport
“Stroke” describes a clinical syndrome, not a single etiology. Ischemic arterial occlusion, intracranial hemorrhage, cerebral venous thrombosis and stroke mimics require different reasoning and sometimes mutually incompa…
01 · Cerebrovascular systems and sterol transport
Imaging can uncover more than one vascular abnormality. The presence of a thrombus, plaque or stenosis does not prove that it caused a particular infarct. This paper proposes an anatomical-concordance method for interpre…
01 · Cerebrovascular systems and sterol transport
Bilateral paramedian thalamic infarction can follow occlusion of a single variant perforating artery arising from the posterior cerebral circulation: the artery of Percheron. Because the presentation can include altered…
01 · Cerebrovascular systems and sterol transport
A sudden neurological deficit followed by abnormal movements creates a diagnostic trap: observers may reclassify the entire episode as a seizure and abandon the stroke differential. This paper argues that the order of ev…
02 · Metabolic neuropsychiatry and neurological clearance
Psychosis, depression and personality change can sometimes arise within inherited disorders of cholesterol trafficking or bile-acid synthesis. Cerebrotendinous xanthomatosis and Niemann–Pick type C are compelling clinica…
02 · Metabolic neuropsychiatry and neurological clearance
Psychosis describes disturbances in perception, belief or thought; it does not by itself establish etiology. This paper proposes an etiologically layered differential that includes primary psychiatric disorders alongside…
02 · Metabolic neuropsychiatry and neurological clearance
The blood–brain barrier is often described only as a wall excluding harmful material. Yet its endothelial cells also actively supply essential molecules. Research identifying MFSD2A as a carrier for lysophosphatidylcholi…
02 · Metabolic neuropsychiatry and neurological clearance
Neurodegeneration is often discussed through proteins that accumulate in brain tissue. This paper asks how protein and lipid clearance systems, vascular health, sleep and cerebral fluid transport might interact to shape…
02 · Metabolic neuropsychiatry and neurological clearance
Bile-acid signatures differ across liver disease, medication use, microbiome composition and metabolic states. Experimental evidence links bile-acid receptors to neural and inflammatory signaling, creating a plausible qu…
02 · Metabolic neuropsychiatry and neurological clearance
Parkinsonism is a pattern of motor findings, not a single diagnosis. Bradykinesia, rigidity, tremor, postural change and gait disturbance can arise through idiopathic Parkinson disease, atypical neurodegeneration, medica…
02 · Metabolic neuropsychiatry and neurological clearance
Ketone bodies become more available during carbohydrate restriction and fasting and can serve as substrates for cerebral energy metabolism. This paper asks when altered fuel availability might influence psychiatric outco…
02 · Metabolic neuropsychiatry and neurological clearance
Pregnancy and birth involve abrupt endocrine transitions, sleep disruption, inflammatory changes and altered caregiving demands. In a small subset of new parents, severe mood or psychotic syndromes develop during this pe…
02 · Metabolic neuropsychiatry and neurological clearance
Oxalate can be medically consequential in specific metabolic and renal contexts, but claims that ordinary vegetable servings trigger psychiatric collapse are not established. This paper explores a carefully bounded hypot…
03 · Hepatobiliary, cholesterol and endocrine physiology
A patient may report food-related discomfort, altered bowel habits or intolerance to fatty meals without an obvious gallstone or duct obstruction. Could selected functional disturbances of biliary physiology contribute t…
03 · Hepatobiliary, cholesterol and endocrine physiology
Bile physiology and endocrine physiology influence each other, but claims that impaired bile directly causes generalized hormone deficiency go beyond current evidence. This paper maps known feedback between bile-acid syn…
03 · Hepatobiliary, cholesterol and endocrine physiology
Cholesterol is indispensable for cell membranes, myelin and steroid synthesis, yet excessive atherogenic lipoprotein exposure contributes to cardiovascular disease. This paper explores cholesterol clearance as an active…
03 · Hepatobiliary, cholesterol and endocrine physiology
The intestine, liver and nervous system exchange signals through nutrients, bile acids, inflammatory mediators, microbial products and neural pathways. This paper proposes a feedback model in which changes in one compart…
03 · Hepatobiliary, cholesterol and endocrine physiology
Fiber can alter intestinal transit, stool composition, microbial fermentation and, in some contexts, bile-acid binding. Yet both “fiber is essential for everyone” and “fiber traps toxins and makes everyone ill” are exces…
03 · Hepatobiliary, cholesterol and endocrine physiology
Drugs can affect liver cells, bile transporters, gallbladder function and intestinal motility. This paper examines medication-related biliary symptoms as a concrete and potentially overlooked part of differential diagnos…
03 · Hepatobiliary, cholesterol and endocrine physiology
Cholecystectomy changes bile storage and timed delivery, but it does not stop the liver from synthesizing bile acids. This paper explores the physiologic consequences of removing the reservoir, including altered enterohe…
04 · Microvascular and cardiometabolic risk
Retinal vein occlusion is an eye emergency and a possible indicator of broader vascular vulnerability. Meta-analytic evidence links retinal vein occlusion with increased future stroke incidence, but an association is not…
04 · Microvascular and cardiometabolic risk
Standard lipid panels can conceal clinically relevant differences in lipoprotein particle number. This paper explains why apolipoprotein B can add information when LDL cholesterol, non-HDL cholesterol and triglycerides a…
04 · Microvascular and cardiometabolic risk
HbA1c estimates glycemic exposure indirectly through hemoglobin glycation; fasting plasma glucose captures concentration at a particular moment. Disagreement between them need not be a laboratory error. This paper examin…
04 · Microvascular and cardiometabolic risk
Microvessels respond to blood pressure, glucose, hematocrit, vascular tone and hormonal signals. This paper evaluates endocrine and hematologic contributors to microvascular vulnerability without suggesting that one “hor…
04 · Microvascular and cardiometabolic risk
Dietary nitrate can influence nitric-oxide pathways and some vascular measurements. That physiologic activity does not prove that beetroot or celery juice treats a prior stroke or prevents recurrence. This paper explains…
05 · Fasting, environmental exposure and metabolic recovery
Adipose tissue stores triglycerides and can accumulate certain lipophilic environmental contaminants. During weight loss, mobilization of tissue stores may alter circulating concentrations of some compounds. This paper p…
05 · Fasting, environmental exposure and metabolic recovery
Weight loss often slows after an initial period of rapid change. This paper argues that a plateau is an interaction between expenditure, intake, body composition, hormonal adaptation and measurement rather than evidence…
05 · Fasting, environmental exposure and metabolic recovery
Fasting alters peripheral fuel availability and can shift cerebral uptake toward ketones under certain conditions. Subjective clarity, fatigue, irritability or calm may occur, but these experiences cannot independently p…
05 · Fasting, environmental exposure and metabolic recovery
Prolonged dietary restriction changes renal sodium handling, body water, potassium balance, magnesium intake and acid-base physiology. This paper argues against a universal electrolyte ratio for all people fasting or eat…
05 · Fasting, environmental exposure and metabolic recovery
After prolonged food restriction, a meal may cause unexpected bloating, fatigue, nausea or changes in bowel function. This paper examines several competing mechanisms: altered gut motility, food load, pancreatic and bili…
05 · Fasting, environmental exposure and metabolic recovery
“Reset” is a useful metaphor but an imprecise medical claim. Temporary ketogenesis, improved fasting glucose, altered appetite and weight loss may reverse when eating patterns change. This paper asks which adaptations en…
05 · Fasting, environmental exposure and metabolic recovery
Scale weight is a convenient measurement, but it cannot summarize health. This paper distinguishes fat reduction from preservation of muscle, skeletal health, functional capacity, mental wellbeing and vascular risk. Its…
06 · Parasitology, infection and neuroimmune disease
Some infections generate symptoms, inflammatory markers and organ manifestations that overlap with autoimmune disease. Others can coexist with autoimmune conditions and become dangerous during immunosuppressive therapy.…
06 · Parasitology, infection and neuroimmune disease
A parasite can produce neurological symptoms through discrete lesions rather than vague systemic “neurotoxicity.” Neurocysticercosis is a particularly clear example of an infection that can cause seizures and focal neuro…
06 · Parasitology, infection and neuroimmune disease
A negative diagnostic test reduces the probability of disease according to its sensitivity and the pretest probability. It does not make infection impossible. This paper examines why stool-based parasite investigations c…
06 · Parasitology, infection and neuroimmune disease
Strongyloides stercoralis demonstrates how a chronic parasitic infection can remain clinically quiet yet become dangerous under altered host immunity. Because its autoinfective life cycle can maintain infection for years…
06 · Parasitology, infection and neuroimmune disease
Trypanosoma cruzi infection can cause chronic cardiomyopathy, and cardiomyopathy may create a setting for embolic stroke. This paper traces that indirect route rather than attributing stroke to parasites directly blockin…
06 · Parasitology, infection and neuroimmune disease
Eosinophils, mast cells and type-2 immune responses participate in host defense against some parasitic infections, yet similar immune signatures can occur in allergy, medication reactions and primary immune disorders. Th…
07 · Vaccine safety, evidence and methodological criticism
A schedule consists of products, doses and timing relationships, not one medicine. This paper asks whether the evidentiary basis for licensed vaccines is supplemented by adequate evaluation of coadministration patterns a…
07 · Vaccine safety, evidence and methodological criticism
Rare adverse reactions may escape prelicensure trials even when those trials are appropriately designed. Detection power depends on how many people receive the product, event incidence, time at risk and clinical outcome…
07 · Vaccine safety, evidence and methodological criticism
Vaccinated and unvaccinated populations often differ before an injection is given. They may vary in health care access, healthcare-seeking behavior, prior infection, chronic disease, socioeconomic conditions and reasons…
07 · Vaccine safety, evidence and methodological criticism
Population-average safety estimates cannot reveal every individual risk pattern. Certain recognized vaccine reactions vary by age, sex, product or medical history. This paper explores whether more refined immunologic or…
07 · Vaccine safety, evidence and methodological criticism
Autoimmune illness can begin around the same period as vaccination because both are common enough to coincide within large populations. The scientific question is whether incidence exceeds the expected background rate in…
07 · Vaccine safety, evidence and methodological criticism
A risk associated with a vaccine is never fully understood in isolation from the risk of the infection it aims to prevent. This paper argues for a dynamic comparison that varies by age, sex, baseline immunity, disease pr…
08 · Signals, measurement and responsible medical AI
A single photograph or laboratory result is a snapshot of physiology; a sequence of observations reveals change. This paper advances a longitudinal phenotype model in which images, symptoms, movement patterns and biometr…
08 · Signals, measurement and responsible medical AI
Some diseases generate measurable changes before a person perceives symptoms, and digital systems may identify patterns earlier than casual human observation. Yet early detection is valuable only if predictions are accur…
08 · Signals, measurement and responsible medical AI
Skin, eyes, nails and oral tissues can display clues to systemic disease. Jaundice, cyanosis, pallor, edema, mucosal abnormalities and certain movement findings are clinically useful in appropriate contexts. This paper a…
08 · Signals, measurement and responsible medical AI
Gait, tremor and fine motor movements are observable manifestations of nervous-system function. Video and wearable sensors may capture frequency, amplitude, speed and asymmetry more consistently than informal description…
08 · Signals, measurement and responsible medical AI
Consumer wearables can gather heart rate, movement, sleep estimates and in some devices temperature-related signals over long periods. Changes relative to baseline may precede recognized illness in selected contexts. Thi…
08 · Signals, measurement and responsible medical AI
A health-screening tool can have respectable sensitivity and specificity and still generate mostly false alarms when applied to rare conditions. This paper makes base rates, calibration and abstention central to medical…
08 · Signals, measurement and responsible medical AI
A laboratory panel is a collection of measurements whose information value depends on how results are combined and interpreted. This paper examines whether longitudinal patterns in routine markers can produce more useful…
