Gospel: (Mark 8:14–21)

Reflection:

In today’s Mass Reading a homily is from Daily TV Mass Canada. The first reading, Saint James reminds us to persevere in temptation, as a crown of life awaits us in the Kingdom of Heaven.

Temptation means being enticed to sin, being lured to violate God’s commandments. Obviously, God does not tempt us. So where does temptation come from?

Saint Anthony of Egypt taught that there are three sources of temptation: the world, the flesh, and the devil. It is easy to blame the world or the devil, to see ourselves as innocent victims. But even apart from external factors, we all experience an inner weakness. We inherit woundedness-what Father Benedict Groeschel called the “original wound.”

Saint Paul expressed this struggle clearly:
“I do not understand my own actions. For I do not do what I want, but I do the very thing I hate.”

Often, the problem is not knowledge but willpower. We know what is right, yet we struggle to say no-whether to small indulgences or deeper habits.

So what is the best way to calm temptation?

Many saints warn that temptation is like an avalanche. It begins small but quickly builds momentum. The best time to say no is at the very beginning.

Psychology even confirms this wisdom. Walter Mischel’s “Marshmallow Test” showed that delayed gratification is linked to later success in life. Discipline matters.

Consider Michael Phelps, who trained for six straight years without missing a day. Greatness is not accidental. It requires discipline, sacrifice, and perseverance.

Matthew Kelly said:
“Our lives change when our habits change.”

Overcoming temptation is not just about resisting; it is about replacing vice with virtue: pride with humility, anger with patience, greed with generosity.

Prayer alone does not remove all temptations. God does not simply make life easier-he makes us stronger. Each time we choose to resist temptation, we choose God.

Sometimes, however, our struggles run deeper. Sister Miriam James Heidland reminds us that our repeated sins often reveal our wounds. Like a reflex test, life situations can trigger emotional reactions rooted in past hurt.

When we notice strong, negative reactions, it can be an invitation to healing.

Adam and Eve’s mistake was not only sin but hiding from God. Instead of running toward mercy, they hid in shame.

God is not only Judge -he is Healer.

Let us turn to God, rely on his grace, and allow him to heal our wounds and strengthen us in our struggles.

🙏 

God bless you and have a wonderful Day.

CHF

Heart Failure

Introduction and Overview: 

Heart failure is one of the most common medical conditions I see and deal with at work and so, I wanted to research and write on it.

Heart failure, also known as congestive heart failure (CHF), framed within the context of clinical medicine. The presenter emphasizes that understanding heart failure begins with mastering its pathophysiology, terminology, and major classifications.

Heart failure is presented not as a single disease, but as a clinical syndrome resulting from impaired cardiac function.

Types of Heart Failure

Heart failure is broadly categorized into:

• Left heart failure

• Right heart failure

• High-output heart failure (less common)

Left Heart Failure

Left heart failure, the most common form, is divided into:

1. Systolic Heart Failure (HFrEF)

Systolic failure results from reduced contractility of the left ventricle.

Common causes include:

• Myocardial infarction (fibrosis replacing functional myocardium)

• Dilated cardiomyopathy (thin, weakened ventricular walls)

• Myocarditis (less common)

Key mechanism:

• Decreased contractility
  → Reduced left ventricular ejection fraction (LVEF)

When LVEF < 40%, this is termed:

Heart Failure with Reduced Ejection Fraction (HFrEF)

Consequences:

• Decreased cardiac output

• Impaired forward blood flow

2. Diastolic Heart Failure (HFpEF)

Diastolic failure involves impaired ventricular filling, not pumping.

Common causes include:

• Chronic hypertension

• Aortic stenosis

These conditions increase afterload, leading to:

• Left ventricular hypertrophy (LVH)

• Thickened ventricular walls

• Reduced filling space

Key mechanism:

• Decreased preload
  → Preserved ejection fraction

When LVEF ≥ 40–50%, this is termed:

Heart Failure with Preserved Ejection Fraction (HFpEF)

Important note:
Both systolic and diastolic failure reduce cardiac output, but through different mechanisms.

Compensatory Mechanisms

A fall in cardiac output leads to reduced blood pressure:

BP = CO × SVR

To compensate, the body increases:

• Systemic vascular resistance (SVR)

• Sympathetic nervous system activity

• Renin–angiotensin–aldosterone system (RAAS) activation

Sympathetic Activation

Triggered by baroreceptors sensing low blood pressure:

• Norepinephrine & epinephrine release

• β₁ stimulation → Increased heart rate

• α₁ stimulation → Vasoconstriction

Short-term benefit: Maintains perfusion
Long-term harm:

• Increased afterload → Worsened hypertrophy

• Increased preload → Ventricular dilation

RAAS Activation

Reduced renal perfusion stimulates renin release:

Renin → Angiotensin I → Angiotensin II (via ACE)

Effects of Angiotensin II:

• Vasoconstriction

• Aldosterone release → Sodium & water retention

• ADH secretion → Water retention

Result:

• Increased preload

• Fluid overload

• Edema

Counter-Regulation: ANP

Atrial Natriuretic Peptide (ANP) is released from stretched atria:

• Promotes natriuresis

• Causes vasodilation

• Inhibits RAAS

This mechanism attempts to limit heart failure progression.

Right Heart Failure

Right heart failure shares similar principles.

Systolic Dysfunction

Caused by:

• Right ventricular myocardial infarction

Leads to:

• Reduced contractility

• Dilated right ventricle

• Reduced RVEF

Diastolic Dysfunction

Most commonly due to pulmonary hypertension, which increases afterload.

Causes of pulmonary hypertension include:

• Idiopathic

• Left heart disease

• Lung disease

• Chronic thromboembolism

• Systemic diseases

Leads to:

• Right ventricular hypertrophy

• Impaired filling

• Reduced cardiac output

High-Output Heart Failure

A rare condition where:

Cardiac output is elevated but still insufficient

Primary mechanism:

• Massive peripheral vasodilation
  → Markedly reduced SVR

Causes include:

• Sepsis (most common)

• Thiamine deficiency (beriberi)

• Thyrotoxicosis

• AV fistulas

• Severe anemia

Despite increased heart rate and stroke volume, tissue demands remain unmet.

Complications of Heart Failure

Left Heart Failure

Pulmonary congestion & edema:

• Elevated left atrial pressure

• Increased pulmonary venous pressure

• Elevated pulmonary capillary wedge pressure (PCWP)

Symptoms:

• Dyspnea

• Orthopnea

• Paroxysmal nocturnal dyspnea

Severe cases → Acute decompensated heart failure

Cardiogenic Shock

Markedly reduced cardiac output → Systemic hypoperfusion

Clinical signs:

• Cold, pale extremities

• Mottling

• Organ dysfunction

Possible consequences:

• Encephalopathy

• Myocardial ischemia

• Acute kidney injury (cardiorenal syndrome)

• Mesenteric ischemia

• Lactic acidosis

Right Heart Failure

Due to elevated central venous pressure:

• Jugular venous distension

• Peripheral edema

• Hepatic congestion

• Ascites

Rarely → Cardiogenic shock via septal shift

Diagnosis

1. Chest X-ray

May show:

• Cardiomegaly

• Pulmonary edema

• Pleural effusions

• B-lines

2. BNP / NT-proBNP

• Low levels → HF unlikely

• High levels → Supports diagnosis

3. Echocardiogram

Essential for:

• LVEF assessment

• Differentiating HFrEF vs HFpEF

• Detecting valvular disease

4. Physical Exam

Helps distinguish:

• Right vs left heart failure

5. Right Heart Catheterization

Gold standard for PCWP

• PCWP > 18 mmHg → Strongly suggests left heart failure

Treatment

Management focuses on neurohormonal modulation.

Core Therapies

β-blockers (metoprolol, carvedilol):

• Reduce sympathetic activation

• Improve remodeling

ACE inhibitors / ARBs / ARNIs:

• Suppress RAAS

• Reduce remodeling & mortality

Aldosterone antagonists:

• Reduce fluid retention

• Improve outcomes

SGLT2 inhibitors:

• Promote diuresis

• Provide cardiovascular benefits

Alternative Vasodilator Therapy

For selected patients:

• Hydralazine + Isosorbide dinitrate

Symptom Control

Diuretics:

• Relieve congestion

• Reduce preload

Device Therapy

CRT → For LVEF < 35% with LBBB
AICD → Prevent sudden cardiac death

Advanced Support

• LVAD → Bridge to transplant

• Inotropes (dobutamine, milrinone) → Short-term support

• IABP

• VA ECMO

Acute Decompensation

• BiPAP → Reduces preload & afterload

• Oxygenation support

Systematic Treatment Algorithm

1. Modify risk factors

2. Start ACEi/ARB + β-blocker

3. Add diuretics if congested

4. Add aldosterone antagonist + SGLT2 inhibitor

5. Switch to ARNI if appropriate

6. Consider hydralazine/nitrates when indicated

7. Add CRT for electrical dyssynchrony

8. Use inotropes if unstable

9. Mechanical support if refractory

10. LVAD / Transplant for end-stage disease

Key Insights

• Heart failure is a syndrome, not a single disease

• Systolic and diastolic dysfunction differ mechanistically

• Compensatory systems initially help but ultimately worsen HF

• Diagnosis integrates imaging, biomarkers, and hemodynamics

• Treatment targets neurohormonal pathways, volume status, and cardiac mechanics

Understanding pathophysiology is essential for:

• Clinical reasoning

• Treatment selection

• Exam preparation

Mass Readings and Reflection for Monday Feb 16, 2026

First Reading: (James 1:1–11)

Responsorial Psalm: (Psalm 119:67, 68, 71, 72, 75, 76)

Alleluia: (John 14:6)

Gospel: (Mark 8:11–13)

Today's first reading and the Gospel, emphasizes the realities of human struggle, uncertainty, and faith.

In the reading, Saint James’ call to “consider it all joy” in trials is not an invitation to ignore pain, but to recognize that trials refine and strengthen us. Difficulties such as illness, loss, stress, and daily burdens are not meaningless interruptions; they are experiences through which perseverance is formed. James’ instruction to ask God for wisdom. God gives generously, but asks for faith without doubt. A divided heart, he notes, leads to instability.

Turning to the Gospel, the Pharisees demand a sign, not out of faith, but as a test. Jesus’ deep sigh reveals His sorrow, because He has already given abundant signs through His words and works. Their request is for proof rather than trust.

On a personal application, many of us believers similarly desire dramatic, unmistakable answers from God- a “neon sign” that fixes problems instantly or removes uncertainty. When such visible signs do not appear, faith can weaken.

We must be reminded that God often works quietly and steadily. His signs are frequently found in daily grace: the strength to endure hardship, unexpected kindness, inner peace, a movement of conscience, and above all, the presence of Christ.

Finally, when experiencing trials, we should not strive to flee from them, but to offer them to God. Perseverance, when allowed to do its work, leads to spiritual maturity. We should remember that the greatest sign has already been given to us-Jesus Himself-who does not abandon His people but leads them through every storm.

We must pray daily for wisdom, steadfast faith, and the grace to discover joy even within trials.

God bless and have a blessed day

Sunday Mass Readings and Reflection– February 15th, 2026

1st Reading: (Sirach 15:15–20)

Responsorial Psalm: (Psalm 119)

Response: 

Blessed are they who follow the law of the Lord!

2nd Reading: (1 Corinthians 2:6–10)

Gospel: (Matthew 5:17–37)

Jesus teaches that He has come not to abolish the Law but to fulfill it. He deepens the commandments:

• Anger is connected to murder.
• Lust is interior adultery.
• Oaths should be unnecessary-let your “Yes” mean yes.

Reflection:

1. Freedom With Responsibility (Sirach)

God trusts us with an incredible gift: freedom.
But with freedom comes responsibility:

• to choose good,
• to resist evil,
• and to recognize that our decisions shape our spiritual destiny.

Sirach reminds us: God never pushes us toward sin- we do that ourselves.

Question for prayer:
What choices am I making today that lead me toward life? Which lead me away from God?

2. God’s Wisdom Isn’t the World’s Wisdom (1 Corinthians)

St. Paul contrasts the “wisdom of this age” with God’s hidden wisdom-something the world cannot grasp.
We often chase:

• intellect,
• power,
• influence,
• human approval.

But God reveals His deepest wisdom not through worldly success but through the Holy Spirit speaking in our hearts.

Question for prayer: Am I seeking God’s wisdom in silence, Scripture, and prayer- or just relying on my own reasoning?

3. Jesus Goes to the Heart (Matthew 5)

Jesus doesn’t just want external obedience; He wants a transformed heart.

He teaches us:

• Anger isn’t harmless- it corrodes the soul.
• Lust isn’t private-it distorts our ability to love.
• Our words shouldn’t need swearing-truth should flow naturally from us.

Jesus fulfills the Law by revealing its deepest intention:
Love God completely. Love others deeply. Love with integrity.

Question for prayer:
Where is Jesus inviting me to deeper interior conversion? Anger? Purity? Integrity? Forgiveness?

4. Reconciling Before Worship

Jesus says: “First go and be reconciled with your brother.”

Reconciliation isn’t optional- it’s central to worship.Our relationship with God is inseparable from our relationships with others.

Question for prayer:
Is there someone God is asking me to forgive or reach out to?

Amen.

Understanding and Managing High Blood Pressure Readings

• Many individuals live with uncontrolled high blood pressure without realizing it, increasing the risk of serious health complications later.

• Blood pressure fluctuates throughout the day depending on emotional state and activity level, including rest, exercise, and stress.

1. Limitations of Blood Pressure Medication

• Medications often function as temporary solutions for problems rooted in lifestyle.

• Approximately 50% of patients do not achieve adequate control with a single medication.

• Nearly 75% of individuals fail to reach optimal blood pressure targets even while on treatment.

• Common side effects of medications such as calcium channel blockers may include:

  • Slowed heart rate

  • Impaired muscle contraction, which may contribute to swelling or constipation

  • Fatigue

  • Headaches

  • Irregular heartbeats

2. Natural Approaches: Nutrition and Lifestyle

Foods Associated with Blood Pressure Reduction

Flax seeds

• Often referred to as “brown gold.”

• May reduce diastolic pressure.

• Associated with reduced risks of stroke and heart disease.

• Additional benefits may include improvements in cholesterol, triglycerides, blood sugar, inflammation, and digestive health.

Hibiscus tea

• Rich in antioxidants.

• Can contribute to modest reductions in blood pressure.

• Even small decreases in blood pressure are linked to meaningful reductions in cardiovascular risk.

Leafy greens, such as arugula

• High in dietary nitrates that support nitric oxide production.

• Nitric oxide helps relax blood vessels naturally.

• This mechanism supports vascular function without many medication related side effects.

Beets and beet greens

• Rich in compounds that promote nitric oxide formation.

• Regular consumption has been associated with blood pressure improvements.

Herbs such as basil and cilantro

• Provide antioxidants and beneficial plant compounds.

• Easily incorporated into a variety of dietary patterns.

Swiss chard

• Contains high levels of dietary nitrates.

• Supports vascular health and endothelial function.

Additional Dietary Considerations

• Limiting sugary beverages may help prevent blood pressure spikes and reduce long term health risks.

• Whole grains are associated with lower risks of diabetes, cardiovascular disease, and weight gain.

• Refined grains are linked to increased metabolic and cardiovascular risk.

• Traditional dietary patterns often supported longevity without modern pharmacological interventions, underscoring the importance of nutrition.

3. Exercise and Monitoring

• Physical activity plays a central role in blood pressure regulation.

• Even short periods of movement can produce measurable reductions.

• Blood pressure varies with posture, activity, and emotional stress, making regular home monitoring valuable.

• Clinically validated home blood pressure monitors improve measurement accuracy.

• Measurements taken during different conditions, including rest and activity, provide a more complete picture of blood pressure behavior.

4. Understanding the Impact of Blood Pressure

• Blood pressure can be compared to accumulating debt within the cardiovascular system.

• It is often ignored until a major event occurs.

• Chronic elevation contributes to thickening of the heart muscle, increasing the risk of heart attack, stroke, and heart failure.

• Long term control is essential for preserving overall health.

• Lifestyle modification, including diet and exercise, remains foundational. Medication serves as an adjunct rather than a replacement.

5. Historical Perspective

• Before the development of modern antihypertensive drugs, management focused on rest and lifestyle adjustments.

• Historical examples illustrate the consequences of uncontrolled hypertension.

• While modern medicine offers effective therapies, nutrition and physical activity remain indispensable.

Summary

• High blood pressure is a serious and often underestimated condition.

• Medications are helpful but have limitations and potential side effects.

• Nutritional strategies, including flax seeds, hibiscus tea, leafy greens, beets, herbs, and whole grains, may support blood pressure control.

• Regular physical activity and consistent monitoring are essential.

• A comprehensive, lifestyle centered approach provides the strongest protection against long term complications.

Spiritual warfare is real-and it’s constant

Apostle Paul reminds us in Ephesians 6 to put on the whole armor of God, not just the pieces we find convenient. This battle isn’t fought in our own strength but in the power of God’s might.

Every day we stand against the enemy’s schemes by:

• Anchoring ourselves in God’s Word
• Walking in truth and righteousness
• Staying alert and sober-minded
• Leaning on the Holy Spirit for wisdom and endurance

Stand firm. Stay ready. The fight is real, but so is the victory in Christ.

Digestive System Overview A Quick Summary

Digestive System Overview a Quick Notes

1. Organs of the Digestive System & Their Functions

A. Oral Cavity

• Teeth – Mechanical digestion (mastication); breaks food into smaller pieces.

• Endocrine
  • Islets of Langerhans
  • Insulin & glucagon

Spleen

(Not digestive but shares blood supply)

• Filters blood
• Recycles old RBCs
• Produces immune cells

3. Vascular Supply

Digestive organs are grouped by embryologic foregut, midgut, hindgut.

A. Foregut

Organs:

• Stomach
• Liver, gallbladder
• Pancreas
• Spleen
• 1st & 2nd part of duodenum

Arterial supply:
✔ Celiac trunk

Venous drainage:
✔ Gastric, splenic veins → portal vein

B. Midgut

Organs:

• Distal duodenum
• Jejunum, ileum
• Cecum, appendix
• Ascending colon
• Proximal 2/3 transverse colon

Arterial supply:
✔ Superior mesenteric artery (SMA)

Venous drainage:
✔ Superior mesenteric vein → portal vein

C. Hindgut

Organs:

• Distal 1/3 transverse colon
• Descending colon
• Sigmoid
• Rectum

Arterial supply:
✔ Inferior mesenteric artery (IMA)

Venous drainage:
✔ Inferior mesenteric vein → splenic vein → portal vein

Key Anastomoses

• Foregut ↔ Midgut: Pancreaticoduodenal arteries
• Midgut ↔ Hindgut: Marginal artery of Drummond

4. Innervation of the GI Tract

Sympathetic (inhibits digestion)

• Foregut: Greater splanchnic (T5–T9) → celiac ganglion
• Midgut: Lesser splanchnic (T10–T11) → SMA ganglion
• Hindgut: Lumbar splanchnic (L1–L2) → IMA ganglion

Effects:

• Decreased peristalsis
• Decreased secretion
• Increased sphincter tone

Parasympathetic (stimulates digestion)

• Foregut & midgut: Vagus nerve
• Hindgut: Pelvic splanchnic nerves (S2–S4)

Effects:

• Increased peristalsis
• Increased secretions
• Decreased sphincter tone

Digestive System in One Sentence

Food is mechanically and chemically processed in the mouth → broken down in the stomach → digested and absorbed in the small intestine → water reclaimed in the large intestine → waste removed through rectum and anus, all supported by liver, gallbladder, and pancreas.

Are you amazed or what about the mystery of this human GI system? That is the notes from class the other day.
