Blood Glucose Levels Hemoglobin A1c Test Cholesterol/HDL Ratio Homocysteine and 25-Hydroxy Vitamin D These tests measure levels of key heart-protective nutrients. “Your homocysteine measures your folate status and should be between 6 and 8 micromoles per liter,” Hyman states. Genetic Testing…drjgeneticsupport.com Level 1 Testing is included in our care plans! LEVEL 2: BNP (B-type Natriuretic Peptied) BNP is a substance secreted from the ventricles or lower chambers of the heart in response to changes in pressure that occur when heart failure develops and worsens. The level of BNP in the blood increases when heart failure symptoms worsen, and decreases when the heart failure condition is stable. The BNP level in a person with heart failure – even someone whose condition is stable – is higher than in a person with normal heart function. Results: • BNP levels below 100 pg/mL indicate no heart failure. • BNP levels of 100-300 pg/mL suggest heart failure is present. • BNP levels above 300 pg/mL indicate mild heart failure. • BNP levels above 600 pg/mL indicate moderate heart failure. • BNP levels above 900 pg/mL indicate severe heart failure. LEVEL 3 ADVANCED LIPID TESTS: Advanced Lipid Tests: Unlike the standard lipid panel, advanced tests like the NMR Lipid Profile or the Cardio IQ Lipoprotein Fractionation look at the all-important particle size of LDL and HDL. “You should have less than 1,000 total LDL particles and no more than 400 small particles (although ideally you shouldn’t have any!),” notes Mark Hyman, MD, director of the Center for Functional Medicine at the Cleveland Clinic, in his new book, Eat Fat, Get Thin: Why the Fat We Eat Is the Key to Sustained Weight Loss and Vibrant Health. Oxidized LDL Test: This test measures the amount of oxidized LDL in the blood. When small, dense LDL particles become oxidized or rancid, they can trigger the process that leads to heart disease. Lp-PLA2 Test: Both Elyaman and integrative cardiologist Mimi Guarneri, MD, FACC, a functional-medicine cardiologist in La Jolla, Calif., recommend this test, which measures an enzyme that contributes to inflammation and atherosclerosis. Carotid Intima-Media Thickness (CIMT) Test: This high-resolution ultrasound test identifies plaque in the arteries in your neck, which is associated with cardiovascular-disease risk. “We want to know how inflamed your major vessels are and how much plaque you are creating, so we look at your carotid arteries, which highly correlate with what’s happening in the heart vessels,” says P. Michael Stone, MD, MS, a family physician who practices functional medicine in Ashland, Ore., and a faculty member at the Institute for Functional Medicine.

The Problem with Physiology by Rinaldo Bellomo
Critical care clinicians can change physiology with a number of tools. The can repeatedly, often and mercilessly change physiological variables. They can increase the blood pressure (or decrease it); they can increase cardiac output (or decrease it), they can increase cardiac filling pressures (or decrease them), they can increase glucose levels (or decrease them), they can increase positive fluid balance (or decrease it) and so on. This kind of “numerology” is attractive because the outcomes are tautological and clinicians feel powerful and effective. However, outside the obvious situations where physiology is so dangerously abnormal as to threaten life, such physiological manipulations have an unproven relationship with outcome. Importantly, patients do not care whether their cardiac output has been increased from 5L/min to 6 L/min. They only care whether they live or die, get out of hospital intact and return to their previous life. Thus, physiological gain is not patient centred. Moreover, all research focusing of the physiology of a specific intervention always and inevitably deals with the effect on a specific set of variables. For example and fluid bolus may or may not increase cardiac output for a while. Thus studies focus on identifying fluid responders for such purposes. However, no one studies the effect of such fluid bolus on anything other than hemodynamics. No one measures what the effect is on the immune system, cerebral edema, the glycocalyx, interstitial oxygen gradient, pulmonary congestion, body temperature, haemoglobin and white cell function etc. etc. Thus, all physiological studies are “blind” to the effects that their protagonists cannot or will not measure. In other words, the measurable is made important but the important may not be measured. Clinicians need to reflect on this before they become seduced by physiological manipulation.

Renin Angiotensin Aldosterone System
This animation focuses on the renin angiotensin aldosterone system (RAAS), a classic endocrine system that helps to regulate long-term blood pressure and extracellular volume in the body. Many aspects of cardiovascular disease progression can be directly linked to the RAAS system. Mechanisms such as vascular inflammation, generation of reactive oxygen species and alterations of endothelial function are all known to play a role in atherosclerosis.

What is BAROREFLEX? What does BAROREFLEX mean? BAROREFLEX meaning, definition & explanation
What is BAROREFLEX? What does BAROREFLEX mean? BAROREFLEX meaning - BAROREFLEX definition - BAROREFLEX explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. The baroreflex or baroreceptor reflex is one of the body's homeostatic mechanisms that helps to maintain blood pressure at nearly constant levels. The baroreflex provides a rapid negative feedback loop in which an elevated blood pressure reflexively causes the heart rate to decrease and also causes blood pressure to decrease. Decreased blood pressure decreases baroreflex activation and causes heart rate to increase and to restore blood pressure levels. The baroreflex can begin to act in less than the duration of a cardiac cycle (fractions of a second) and thus baroreflex adjustments are key factors in dealing with postural hypotension, the tendency for blood pressure to decrease on standing due to gravity. The system relies on specialized neurons, known as baroreceptors, in the aortic arch, carotid sinuses, and elsewhere to monitor changes in blood pressure and relay them to the Medulla. Baroreceptors are stretch receptors and respond to the pressure induced stretching of the blood vessel in which they are found. Baroreflex induced changes in blood pressure are mediated by both branches of the autonomic nervous system – that is the parasympathetic and sympathetic nerves. Baroreceptors are active even at normal blood pressures so that their activity informs the brain about both increases and decreases in blood pressure. The body contains two other, slower acting systems to regulate blood pressure: the heart releases atrial natriuretic peptide when blood pressure is too high, and the kidneys sense and correct low blood pressure with the renin-angiotensin system. Baroreceptors are present in the auricles of the heart and vena cavae, but the most sensitive baroreceptors are in the carotid sinuses and aortic arch. While the carotid sinus baroreceptor axons travel within the glossopharyngeal nerve (CN IX), the aortic arch baroreceptor axons travel within the vagus nerve (CN X). Baroreceptor activity travels along these nerves directly into the central nervous system to contact neurons within the nucleus of the solitary tract (NTS) in the brainstem. Baroreceptor information flows from these NTS neurons to both parasympathetic and sympathetic neurons within the brainstem. The NTS neurons send excitatory fibers (glutamatergic) to the caudal ventrolateral medulla (CVLM), activating the CVLM. The activated CVLM then sends inhibitory fibers (GABAergic) to the rostral ventrolateral medulla (RVLM), thus inhibiting the RVLM. The RVLM is the primary regulator of the sympathetic nervous system, sending excitatory fibers (glutamatergic) to the sympathetic preganglionic neurons located in the intermediolateral nucleus of the spinal cord. Hence, when the baroreceptors are activated (by an increased blood pressure), the NTS activates the CVLM, which in turn inhibits the RVLM, thus decreasing the activity of the sympathetic branch of the autonomic nervous system, leading to a relative decrease in blood pressure. Likewise, low blood pressure activates baroreceptors less and causes an increase in sympathetic tone via "disinhibition" (less inhibition, hence activation) of the RVLM. Cardiovascular targets of the sympathetic nervous system includes both blood vessels and the heart. Even at resting levels of blood pressure, arterial baroreceptor discharge activates NTS neurons. Some of these NTS neurons are tonically activated by this resting blood pressure and thus activate excitatory fibers to the nucleus ambiguus and Dorsal nucleus of vagus nerve to regulate the parasympathetic nervous system. These parasympathetic neurons send axons to the heart and parasympathetic activity slows cardiac pacemaking and thus heart rate. This parasympathetic activity is further increased during conditions of elevated blood pressure. Note that the parasympathetic nervous system is primarily directed toward the heart. The baroreceptors are stretch-sensitive mechanoreceptors. At low pressures, baroreceptors become inactive. When blood pressure rises, the carotid and aortic sinuses are distended further, resulting in increased stretch and, therefore, a greater degree of activation of the baroreceptors. At normal resting blood pressures, many baroreceptors are actively reporting blood pressure information and the baroreflex is actively modulating autonomic activity. Active baroreceptors fire action potentials ("spikes") more frequently. The greater the stretch the more rapidly baroreceptors fire action potentials. Many individual baroreceptors are inactive at normal resting pressures and only become activated when their stretch or pressure threshold is exceeded.

What is WAON THERAPY? What does WAON THERAPY mean? WAON THERAPY meaning & explanation
What is WAON THERAPY? What does WAON THERAPY mean? WAON THERAPY meaning - WAON THERAPY definition - WAON THERAPY explanation. SUBSCRIBE to our Google Earth flights channel - http://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ?sub_confirmation=1 Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Waon therapy, developed in Japan, is a sauna-like form of hyperthermia therapy for patients with chronic heart failure. Waon is a Japanese word meaning soothing warmth. Waon therapy is proposed to improve prognosis and quality of life. The sauna room is an evenly warmed room at 60 °C (140 °F) with no hydration added. Patients sit in it for 15 minutes, after which, they are wrapped in thermal blankets and laid down to maintain heat for 30 minutes. Chronic heart failure patients suffer from an inability to pump enough blood to their tissues and heart, resulting in systolic and/or diastolic dysfunction. Waon therapy improves many indicators of heart function including: cardiac output, stroke volume, ejection fraction, while also having benefits in vascular function including decreased vascular resistance and blood pressure. Improvements were also seen in left ventricular diastolic dimension and left atrial dimension. Patients with aortic stenosis, obstructive hypertrophic cardiomyopathy and ischemic cardiomyopathies should not use Waon therapy as a treatment. Prohibiting patients with ischemic cardiomyopathies prevents an increase in temperature from further activating the sympathetic nervous system, which could cause tachycardia in these patients. Waon therapy increases blood flow by stimulating endothelial nitric oxide synthase protein production (eNOS). eNOS makes nitric oxide, which is a vasodilator and increases blood flow. Waon therapy also increases blood flow by stimulating the mobilization endothelial progenitor cells marked with CD34 molecules. CD34 positive cells promote angiogenesis to increase blood flow, improving cardiac perfusion and decreasing vascular resistance. Nitric oxide is also a regulator of the sympathetic nervous system, and an increase of nitric oxide via endothelial nitric oxide synthase may help to control autonomic nervous system. In chronic heart failure the sympathetic nervous system is over-activated and the parasympathetic nervous system depressed, increasing stress on the heart. Waon therapy increases parasympathetic activity and decreases the sympathetic activity. These changes decrease stress on the heart by decreasing systemic resistance and increasing cardiac output, which decrease preload and afterload. Brain natriuretic peptide (BNP) decreases with Waon therapy. BNP is a negative indicator of cardiac function and is released during ventricular stretching. A 5 year study of Waon therapy showed a decrease in cardiac death and rehospitalisation after cardiac events. This treatment is currently only being used in Japan, but positive results suggest Waon therapy may be a new, non-pharmacological treatment for chronic heart failure patients and other vascular resistance diseases.

USMLE Renal 6: RAAS Pathway, Endocrine Functions and Pharmacology
Welcome to LY Med, where I go over everything you need to know for the USMLE STEP 1, with new videos every day. Follow along with First Aid, or with my notes which can be found here: https://www.dropbox.com/sh/mt1jrikc24022py/AADNAVG8cAj4Su7xFO74fLBka?dl=0 This video is on the RAAS pathway. Your kidneys need a certain amount of blood pressure to filter your plasma! When there is a drop in pressure, it activates the RAAS and this helps us raise our blood pressure by reabsorbing salt and water. How does it do this? In your afferent arteriole, you have special juxtaglomerular cells which sense a drop in pressure and release the enzyme renin. Another things that stimulates renin release is sympathetic response via B1 receptors. Also in your distal convoluted tubule, you have macula densa cells that sense low sodium and release renin. So how does renin reabsorb salt and water? Renin meets a protein called angiotensinogen and converts it to angiotensin I. This moves to the lung where an enzyme called angiotensin converting enzyme turns it into angiotensin II. Angiotensin II does a host of things, including increasing the Na/H pump in the PCT, increase aldosterone which work on the ENAC channel and increase ADH (aquaporin channels). It also stimulates thirst, vasoconstriction especially in your efferent arteriole. What regulates this system and makes sure we don't have too high of blood pressure? Well when your heart gets fluid overloaded it starts to release hormones, including atrial natriuretic peptide and brain natriuretic peptide. This helps us lose water and salt and thus it's a counterregulatory measure. Some pathophysiology tie-in, in heart failure you get fluid overloaded and this raises BNP. We often measure this! Now let's talk about some pharmacology. Drugs that work here help us lower our blood pressure. For example, you have aliskiren, a direct renin inhibitor. Other drugs include ACE inhibitors which stops the conversion to angiotensin II. This is great in diabetic nephropathy as well as those with heart disease and post myocardial infarction. Side effects include cough and angioedema. Also it's a teratogen, causing fetal renal malformation. Another drug includes angiotensin II blockers. This contains less side effects as it doesn't work on the bradykinin system as ACE inhibitors do. Now our last topic will touch on some other endocrine functions of the kidneys. These include: Dopamine: Released in the proximal convoluted tubule, it causes vasodilation. 1 alpha hydroxylase: activates vitamin D Prostaglandins: dilate the afferent arteriole. EPO: released in peritubular capillaries and helps increase RBCs.

Heart Minute | BNP in Congestive and Hypertrophic Heart Failure
In this era of cost containment, home BNP measurement may be in the future for patients with heart failure.
Просмотров: 194 American College of Cardiology
Medical Surgical Cardiovascular System: Congestive Heart Failure (CHF)
Hello Everyone, here is a Cardiovascular lecture on Congestive Heart Failure made easy to understand to help aide in your study sessions. I have gathered all of the important information from my Med- Surg Book (Brunners and Suddarth 12th edition) and NCLEX review (Saunders 6th edition) that will prepare you for your nursing test whether it is for school or NCLEX. Part 2 of this lecture will be located under the Pharmacology section as it continues with cardiac meds that will further explains MOA, side effects, etc. Here are some Extra information that may help and guide you... Two major types of HF are identified by assessment of left ventricular functioning, usually by echocardiogram. The more common type is an alteration in ventricular contraction called systolic heart failure, which is characterized by a weakened heart muscle. The less common type is diastolic heart failure, which is characterized by a stiff and noncompliant heart muscle, making it difficult for the ventricle to fill. An assessment of the ejection fraction (EF) is performed to assist in determining the type of HF. EF is calculated by subtracting the amount of blood present in the left ventricle at the end of systole from the amount present at the end of diastole and calculating the percentage of blood that is ejected. A normal EF is 55% to 65% of the ventricular volume; the ventricle does not completely empty between contractions. The EF is normal in diastolic HF but severely reduced in systolic HF. Although a low EF is a hallmark of systolic HF, which is the most common type of HF, the severity of HF is frequently classified according to the patient’s symptoms. Pathophysiology: Systolic HF results in decreased blood volume being ejected from the ventricle. The decreased ventricular stretch is sensed by baroreceptors in the aortic and carotid bodies. The sympathetic nervous system is then stimulated to release epinephrine and norepinephrine. The purpose of this initial response is to increase heart rate and contractility and support the failing myocardium, but the continued response has multiple negative effects. Sympathetic stimulation causes vasoconstriction in the skin, gastrointestinal tract, and kidneys. A decrease in renal perfusion due to low CO and vasoconstriction then causes the release of renin by the kidneys. Renin promotes the formation of angiotensin I, a benign, inactive substance. Angiotensin- converting enzyme (ACE) in the lumen of pulmonary blood vessels converts angiotensin I to angiotensin II, a potent vasoconstrictor, which then increases the blood pressure and afterload. Angiotensin II also stimulates the release of aldosterone from the adrenal cortex, resulting in sodium and fluid retention by the renal tubules and stimulation of antidiuretic hormone. These mechanisms lead to the fluid volume overload commonly seen in HF. Angiotensin, aldosterone, and other neurohormones (eg, endothelin, prostacyclin) lead to an increase in preload and afterload, which increases stress on the ventricular wall, causing an increase in the workload of the heart. A counterregulatory mechanism is attempted through the release of natriuretic peptides. Atrial natriuretic peptide (ANP) and B-type (ie, brain type) natriuretic peptide (BNP) are released from the overdistended cardiac chambers. These substances promote vasodilation and diuresis. However, their effect is usually not strong enough to overcome the negative effects of the other mechanisms. As the heart’s workload increases, contractility of the myocardial muscle fibers decreases. Decreased contractility results in an increase in end-diastolic blood volume in the ventricle, stretching the myocardial muscle fibers and increasing the size of the ventricle (ventricular dilation). The increased size of the ventricle further increases the stress on the ventricular wall, adding to the workload of the heart. One way the heart compensates for the increased workload is to increase the thickness of the heart muscle (ventricular hypertrophy). However, hypertrophy results in an abnormal proliferation of myocardial cells, a process known as ventricular remodeling. Under the influence of neurohormones (eg, angiotensin II), large myocardial cells are produced that are dysfunctional and die early, leaving the other normal myocardial cells to struggle to maintain CO. The compensatory mechanisms of HF have been called the “vicious cycle of HF” because the heart does not pump sufficient blood to the body, which causes the body to stimulate the heart to work harder; thus, the heart cannot respond and failure becomes worse. Diastolic HF develops because of continued increased workload on the heart, which responds by increasing the number and size of myocardial cells (ie, ventricular hypertrophy and altered cellular functioning). These responses cause resistance to ventricular filling, which increases ventricular filling pressures despite a normal or reduced blood volume.

Effects on the Cardiovascular System
Steroids can lead to the build-up of deposits on the walls of artery a condition called atherosclerosis. The blood's current can cause the deposit to break away from the artery wall, and as the deposit travels through the blood stream it can be wedged against a narrower blood vessel, a common cause of heart attacks. If the deposit gets stuck in the heart it can block blood flow, causing a heart attack; if stuck in the brain, the result could be a stroke.

Atrial Fibrillation - Dr Irina Savelieva
Dr Irina Savelieva, Lecturer in Cardiology, Division of Cardiac and Vascular Sciences, St George's, University of London, talks to Cardio Debate about atrial fibrillation. TRANSCRIPT How to identify patients with AF who are at high risk of stroke? That’s obviously the question that all physicians who face patients with atrial fibrillation for the first time should ask themselves, that’s a very important component of management of atrial fibrillation. And of course there is the CHADS VASC score. This is a very good scheme that has been adopted by many regulatory authorities and guidelines, which is pretty simple. It incorporates major risk factors which are easily identifiable during your first interview with your patient. And it includes congestive heart failure, left ventricular dysfunction, age, hypertension, diabetes, previous stroke, advance stage – well if you can see that some aged over 75 years is advanced, so that’s your answer – and female gender. The problem with the CHADS CASC score is that we don’t have very concrete data in patients with the CHADS VASC score 1, for example. And we don’t know exactly what the weight of separate isolated risk factors are in a patient with the CHADS VASC score of 1, and there were reports that probably these patients are not necessarily at a very high risk of stroke when anticoagulation is warranted. The ESC guidelines however do support anticoagulation in these patients and I think that physicians should follow these guidelines. On the other hand an important thing is that patients with a CHADS VASC score of 0 are not entirely risk free of stroke. Strokes do happen in otherwise healthy persons with atrial fibrillation, with low atrial fibrillation if you will. And this is a particular problem for us physicians, because obviously for such patients stroke is an absolutely devastating consequence of untreated atrial fibrillation that we could have prevented in this case. And we’re trying to develop new markers for example some biomarkers such as brain natriuretic peptide (BNP), troponin, some coagulation parameters in order to assist better risk stratification in this particular patient population. Some imaging techniques, for example MRI of the atria may indicate that certain morphologies of left atrial appendage, for example, may predispose to high risk of stroke. The extent of left atrial fibrosis also has been shown to be associated with increased risk of stroke. So that risk stratification is ongoing, it’s a moving issue. But for the time being, for the clinician, when you first face a patient with atrial fibrillation, do CHADS VASC score and this would help you guide your management in terms of oral anticoagulation. Anticoagulation and bleeding risk: Prevention and treatment Bleeding as a result of oral anticoagulation is of course a dreadful consequence that was probably imposed on the patient by us, the physicians. So therefore numerous schemes have been developed in order to predict such tragic consequence of treatment with oral anticoagulants. We advocate the use of HAS-BLED. That’s a very simple one to calculate, and again it does include factors that are easily identifiable, and most importantly they are, to some extent, modifiable at the same time. For example it helps to highlight patients with poorly controlled hypertension that predisposes to high risk of intracranial bleeding, for example, or patients who are receiving concomitant medications that may potentiate the adverse effects of oral anticoagulants for example gastro-intestinal tract, etc. So by calculating this risk score HAS-BLED, we can identify risk factors that can change and therefore we can reduce the patient’s risk of bleeding. But at the end of the day it is a very fine balance between the risk and benefit. And therefore here we have to exercise an individual approach to the patient. And of course again, here, we also have some new developments. For example there is a very interesting observation that finding micro-bleeds on the MRI of the brain may actually predict the subsequent hemorrhagic stroke or even ischemic stroke, and this would help to risk stratify patients in terms of anti-coagulation. Of course it is mainly a research tool, as well as the previously mentioned imaging of the left atrium as we discussed, but it is a research tool today; tomorrow it will be part of risk stratification (protocols) in terms of bleeding. The role of NOACs in everyday practice: Farewell to warfarin? NOACs or warfarin – that’s a dilemma. NOACs is an acronym for new oral anticoagulants. However, these drugs are not that entirely new, and NOACs now stand for Non-Vitamin K Anti Oral Coagulants, not New or Novel. To read the rest of the transcript please visit www.cardio-debate.com

HORMONES OF HEART, KIDNEY AND GASTROINESTINAL TRACT : HEART : Atrial wall of heart secretes peptide hormone called atrial natriuretic factor ANF which decreases B.P when B.P is increased, ANF is secreted which causes dilation of blood vessels. This reduces B.P. KIDNEY : The juxtraglomerular cells of kidney produce 2 hormones erythropoietinstimulates bone marrow to produce more RBC's and Renin acts on protein angiotensinogen to form angiotersin. Angiotensin raises B.P to increase ultra filtration. Gastro -- intestinal Tract : Endocrine cells present in different parts of gastro intestinal tract secrete 4 major peptide hormones. Gastrin : acts on gastric glands and stimulates the secretion of Hcl and pepsinogen. Secretin -- acts on exocrine pancreas and stimulates secretion of water and bicarbonate ions. Cholecystokinin : acts on both pancreas and gall bladder and stimulates the secretion of pancreatic enzymes and bile juice. Gastric inhibitory peptide : inhibits gastric secretion and motility. Several non endocrine tissues secrete hormones called growth factors. These factors are essential for normal growth and tissues and their repairing / regeneration.

"Hyponatremia in the Critically Ill Child" by Andrea Moscatelli, MD, for OPENPediatrics
Learn about the pathophysiology and types of hyponatremia, and how to properly diagnose and correct hyponatremia through clinical case studies. Please visit: www.openpediatrics.org OPENPediatrics™ is an interactive digital learning platform for physicians and nurses sponsored by Boston Children's Hospital and in collaboration with the World Federation of Pediatric Intensive and Critical Care Societies. It is designed to promote the exchange of knowledge between physicians and nurses around the world caring for critically ill children in all resource settings. The content includes internationally recognized physician and nursing experts teaching the full range of topics on the care of critically ill children. All content is peer-reviewed and open access-and thus at no expense to the user. For further information on how to enroll, please email: openpediatrics@childrens.harvard.edu Please note: OPENPediatrics does not support nor control any related videos in the sidebar, these are placed by Youtube. We apologize for any inconvenience this may cause. My name is Andrea Moscatelli. I'm the director of the Neonatal and Pediatric Intensive Care Unit at the Gaslini Children's Hospital in Genova, Italy. In the next few minutes, we'll talk about the treatment and prevention of hyponatremia in the critically ill child. We will start with the definition and pathophysiology of hyponatremia, then we will go through some case presentation, and we'll focus on the treatment and prevention of hyponatremia. Pathophysiology of Hyponatremia. You have hyponatremia when there is a relative excess of free water with an underlying condition that impairs the kidney's ability to excrete free water. This might happen in the case of excessive intake of water, if there is a marked reduction in the glomerular filtration rate, or if there is a renal hypoperfusion, either if there is an ADH excess. This condition is affecting 25% of the critically ill children. It is considered moderate if sodium is below 130, and this condition is affecting more than 1% of hospitalized children. Serum sodium is strictly regulated by some interplay mechanism. The first one is the incretion of vasopressin. Vasopressin is increted by the posterior hypophysis in response to stimuli, like a reduction in the circulating volume or an increase in plasma osmolarity, while the renin-angiotension-aldosterone system is able to enhance the reabsorption of sodium and water in case of hypovolemia. The sympathetic nervous system has similar effects to the renin-angiotension-aldosterone system. Atrial natriuretic peptide has opposite effects. So if you think about the cell, the main intracellular ion is potassium, while the main extracellular ion is sodium, and urea is able to move freely across the cell membrane. So to measure the plasma osmolarity, you can go through this formula, which takes into account sodium, glucose, and the BUN. But if you think about the driving force for the movement of water across the cell membrane, you should think about tonicity. So you wouldn't take into account urea, which is able to move freely across the cell membrane. And you just take into account sodium and glucose. By using the above formulas for osmolarity and tonicity, or by measuring a patient's osmolarity as a lab value, you can assess whether they are hypo-osmolar or hypotonic, serum osmolarity of less than 280, isotonic serum osmolarity of 280-295, or hypertonic serum osmolarity of greater than 295. A patient's osmolarity and tonicity are important in assessing the causes of hyponatremia.

Recommended screening in Diabetic teens with positive Microalbumin test - Dr. Pradeep Kumar T J
In young diabetic individual, we are most likely looking at Type 1 diabetes. Type 1 diabetes we are looking at absolute deficiency of insulin. These individuals tend to have multiorgan system involvement in the body. As part of this multiorgan system involvement, kidney is one of the organs that can get affected very early in the stage of the disease. Hence even if they have their blood sugar levels being normal, with higher levels of HbA1c levels with microalbumin which indicates that the kidney is losing proteins from the body, this is one of the early indicator of a kidney involvement. This has to be monitored on a daily basis. hence this can be a marker of a kidney disease as a first marker of kidney disease. Hence they need to be checking their kidney functions on a periodic basis, once in 6 months, though their other values can be normal.
