For a person to stay healthy, he has to know the sources of good and bad fats. The body needs fats, because fats or lipids have several functions in the human body, such as, acting as thermal regulators, the basic nucleus of steroid hormones, lung surfactants, and transport proteins. These are good fats, though.

You are the food that you eat. So, if you want to stay healthy and fit, here are some facts that you should know about the fats that you eat.

Sources of bad fats

•    Meat fat

Meat fat is bad fat because it contains low density lipoproteins (LDL) which could elevate your concentrations of lipids in your blood. These are the lipids that accumulate in the arteries causing blockage, atherosclerosis and hypertension. They contain more lipids than fat. Examples of these are pork and chicken fat.

•    Dairy products

Dairy products, such as cheese and milk, are also bad fats or lipids. They contain the same component as meat fats that contain more lipid content than protein. If you could not avoid drinking milk, then choose the non-fat milk.

Sources of good fats

•    Vegetable oils/fats

Vegetable fats are good fats, high density lipoprotein (HDL), which lowers a person’s propensity to cardiac diseases. These types of fats have, also, more protein content than lipid, so they are safer than meat fat.

•    Fish oils/fats

Roasted fish

Cod liver oil and salmon oil great sources of good cholesterol or good fat. These good fats have various physiological functions aside from transporting bad fats from the arteries to be eliminated and metabolized.

Next time you go to a Fast Food restaurant, watch out for those chicken and pork dishes. It’s your choice whether you want to prolong your life expectancy or not. Making the right food choices would allow you to maintain good health and to enjoy your life longer.

The Cardiac Enzymes and Isoenzymes in Myocardial Infarction

When a patient is suspected of having a Myocardial Infarction (M.I.), heart attack, or have had a heart attack, part of the common tests performed are the cardiac enzyme tests. These include CK2 (CKMB,) LD1, and AST. For the non-enzymatic substances, these include myoglobin, Troponin I and Troponin T.

CK2 or CKMB is an isoenzyme of Creatine Phosphokinase (CPK) which is specific for the heart. It is the second fastest-moving CK isoenzyme in electrophoresis.

LDH1 or LD1 is isoenzyme of Lactate Dehydrogenase that is significantly increased in Myocardial Infarction. It is the fastest moving isoenzyme of LD during electrophoresis.

AST is also elevated during M.I. because of its origin in the heart muscles. Together with CK2 and LD1, they could help doctors in the diagnosis of M.I.

Non-enzymatic panel tests are should be performed together with the enzymatic to provide more significant data.

The symptoms and other diagnostic tests of the patient should also be integrated when interpreting laboratory results.

The elevation of CK, AST and LD during a heart attack is that CK peaks first, then AST, and then LDH.

Kidney Disease and Its Link with Poor Sleep

To people who do not belong to the medical field, kidney and sleep seemed not to be related to one another. The fact, however, is that sleep is significantly linked to sleep because of scientific reasons. These reasons can be explained through the following statements.

A study entitled: “Quality of Sleep in Patients with Chronic Kidney Disease” conducted by Eduard A. Iliescu et al, yielded a 53 percent prevalence of “poor sleep” in patients with chronic kidney disease. They concluded that: “Depression was the only significant predictor of decreased quality of sleep among the independent variables considered,” and that “There was no association between the degree of renal impairment and the quality of sleep.”

kidney disease and sleep

The study concentrated only with chronic kidney disease, but in patients undergoing dialysis, the researchers have concluded, based on polysomnographic studies done in dialysis patients  that: “renal failure can directly influence quality of sleep because of obstructive sleep apnoea (OSA) and periodic leg movement during sleep (PMLS.)

OSA is characterized by difficulty in breathing because of obstruction in the upper respiratory tract and a destabilization of the ventilator process.  Incidences of disordered breathing, and excessive sleepiness in dialysis patients also caused poor sleep.

Dialysis is done when a patient’s kidney could no longer perform its functions and there is kidney failure. It is a process where the toxic waste products of the body are excreted by using a special machine that eliminates waste products from the blood.

In another study: “Sleep Apnea Syndrome in Chronic Renal Disease” conducted by Kimmel PL et al, a relationship of sleep apnea and chronic renal disease has been raised. According to the researchers: “Some of the daytime sleepiness and disturbed nocturnal sleep in such patients may be related to sleep apnea.” Their results could be used further by future researchers to establish a significant and specific connection between sleep and kidney diseases.

The fact that kidney diseases, most especially those undergoing dialysis, could cause depression and consequently poor sleep could not be denied. The link between poor sleep and other types of kidney diseases has also become more defined with the studies conducted.

One simple condition that could cause sleep disturbances is polyuria characterized by excessive urination secondary to diabetes mellitus. Due to the number of times a person has to urinate, sleeplessness occurs. Oliguria is another kidney condition affecting sleep. It is characterized by less urination. Pain usually accompanies oliguria, so when a person is in pain, he would not be able to sleep properly.

These are some diseases that establish the link between kidney disease and sleep. Whatever condition that affects the body would consequently affect a person’s sleeping patterns as well.

How Stress Increases Your Blood Pressure

Posted 05 Oct 2012 — by admin
Category Diseases and Conditions, Health Procedures, Keeping Healthy

Stress can be a vital cause of hypertension or high blood pressure because of the hormones involved when you are stressed out.

Stress can be good for you, if you know how to cope with it. Stress could allow you to perform better and give your best in any activity that you embark on, as long as you learn how to channel it properly.

Most people, however, channel their stress the wrong way. They allow stress to take over their lives and dictate how they would perform. There are the uncontrolled instances when people are prone to increased blood pressure. You could be a victim, as well, if you don’t know to manage your stress.

Stress is usually caused by the following:

  • Anxiety
  • Change of residence
  • New job
  • New place
  • Any impending major events
  • Exams
  • Activities that are new to the person

Stress could also be relative, so you may have an activity, which other people don’t find stressful, but which you find stressful. Whatever it is, you should know how to delve deep into the root cause so you could cope with it.

Stress and high blood pressure

When you are stressed out, your emergency hormones, catecholamine, are increased in secretion to cope with your stressful situation. These hormones increase your pulse rate, blood circulation and blood pressure by acting as vasoconstrictors, among its other effects. That’s why sometimes when you’re stressed, your physical prowess is increased also; you could carry an object during a raging house fire that you could not previously lift.

The main catecholamines are epinephrine and nor-epinephrine or adrenaline and noradrenaline. According to the Fundamentals of Clinical Chemistry by Calbreath et al, catecholamines are responsible with the “Fight or Flight” response.

If you are not able to cope with stress, it could be detrimental to your health. Stress and anxiety, oftentimes, go hand in hand. Where there’s anxiety, there’s stress, so you have to control your anxious thoughts first.

When you are able to control your anxious thoughts and channel them to more fruitful outputs like writing or meditation, your stressful situation would diffuse and so does your blood pressure.

You could control your blood pressure by knowing how to cope with your stressful situations and changing your mind-set in general. Having an optimistic attitude and responding positively to stress is one major method of lowering your blood pressure.

Different Stress-related Illnesses That You Should Watch Out For

By: Alleluia Reyes

Stress is a very common experience by a lot of people nowadays. As people’s lifestyles have started to become less simple, there are more stressors that each one must handle each and every day. Perhaps because the different stressors have become part of the everyday routines in your life, you have might been so used to it without having realized that this excess amount of stress might harm you because there are a lot of stress-related illnesses. In fact, studies say that fifty percent of medical consultations are suspected to be due to stress-related illnesses.

Stress can either indirectly or directly affect your health. That is why you must pause once in a while, and reflect if your activities at work or in school might already be leading you towards the road to stress-related illnesses. Because a stressful lifestyle is also equivalent to a very unhealthy lifestyle, it has an indirect negative effect to your body’s well-being. People who are very busy have the tendency to have less rest, deprived sleep and no time for exercise and leisure. Furthermore, very busy people resort more to eating in fast foods than preparing their own home-cooked meals. This kind of lifestyle may eventually lead you to stress-related illnesses indirectly.

Stress also can directly cause changes in your bodily reactions that might not be good for your health. When you are stressed, your body physiologically adjusts to be able to cope up with the demands of your condition. Your body tends to release stress hormones such as cortisol and adrenaline to be able to adapt to the stressful situation. However, the increase in release of these hormones might make your body more prone to stress-related illnesses because of the increase in stimulation that it does to your different organ systems, especially the cardiovascular system.

The following are the most commonly identified stress-related illnesses:

  • Hypertension
  • Coronary artery disease
  • Cerebrovascular accident
  • Asthma
  • Tension headaches
  • Migraine
  • Fibromyalgia
  • Acid peptide disease
  • Irritable bowel syndrome
  • Stomach ulcers
  • Insomnia
  • Sexual dysfunction
  • Irregular menstrual cycles

The Curious Tale of Phineas Gage and The Ice Pick King

By: Ming Santos

Even if you have never seen, let alone visited a neurologist or a psychotherapist, you must have, at one point in your life, heard of Phineas Gage.

What do you mean you haven’t heard of him? I mean come on, when a guy survives after getting impaled by a three foot long iron rod in the skull, he tends to become famous. However, that’s not the only interesting thing about Gage. What’s curious about his case is that after he survived, he changed the world of neurology forever.

Phineas “You Make Me Feel Brand New” Gage

On September 13, 1848, 25 year old Gage was just doing his job as a construction foreman for the Rutland and Burlington Railroad in Vermont – he was busy packing explosives on the ground – the charge on the explosives detonated without warning. The iron rod he was using to tamp the explosives into the ground flew with such a force that when it hit his head, the 3 foot 7 inch rod entered his left cheek, went straight through his skull (and brain, of course) and emerged at the top of his head.

Moments later, they loaded him onto a cart and took him to a hotel where some doctor attended to him. Everyone was expecting him to die – Gage was bleeding profusely and the rod caused his left eye to become blind – but, curiously enough, he was able to walk and talk! Weeks after the accident, Gage was allowed to return to work, but his boss wouldn’t give him the same position as before. He complained that Gage had become rude, foul mouthed and irritable whereas before, he was mild-mannered, efficient and polite.

As such, Gage was never allowed to work at his former job again, until such a time that P.T. Barnum, famed exhibitor of “freaks”, hired him and put him on display as a curiosity along with the iron rod which impaled his head. Gage lived 13 years after his accident, dying because of epileptic seizures.

Experiments Galore

Gage’s accident made the enlightened people of the society think that certain portions of the brain can affect an individual’s personality. After studying Gage’s case, a surgeon concluded that tumors located on the frontal lobes of the brain had no effect on the cognitive functions of the brain; however, such localized tumors (or lesions) may indeed produce such uncharacteristic changes in a person’s behavior, as in Gage’s case.

This same surgeon removed a tumor from a patient’s brain in 1894. The patient initially complained that his thinking has become dull. Seeing the similarities between the patient’s mental faculties and Gage’s, he successfully removed the tumor that lay – you said it – in the left frontal lobes of the brain.

Now that they know that certain areas of the brain are responsible for certain functions, scientists became braver in experimenting with the brain. Now here comes the gritty part – when a German scientist discovered that dogs became tamer after the removal of their temporal lobes, doctors at an insane asylum in Sweden started performing lobotomies on hard, restless, even violent patients. As in the case of the German doctor’s dogs, these lobotomized patients became calmer after their surgeries.

The Ice Pick King and the Lobotomy Brouhaha

Lobotomies fell out of favor after a while, that is, until Walter Freeman came.  Freeman created the “superquick” method of performing lobotomies on patients – he locally anesthetized his patients and plunged an ice pick through the skull. Yes, you read it right. As if this wasn’t enough,  Freeman would then swing the ice pick back and forth, effectively severing the frontal lobe.

Ice pick lobotomies only took a few minutes, and it was reported that Freeman would usually set up shop and perform as much as ten lobotomies – not in a day – but in a single afternoon.

Lobotomy became such a craze in the 1960’s until it came to a point wherein it was no longer used to control violent psychiatric patients – homosexuals, “troublesome” personalities, political radicals, even “undesirables” got the treatment. It escalated into such a crescendo that even amateurs got to do it! These amateurs performed lobotomies without even performing psychiatric evaluations of their patients (think of the character Sweet Pea from the movie “Sucker Punch”).

I Rest My Craze

Due to the seemingly crude and inhuman nature of lobotomies, the procedure is now outlawed in most countries, but they are still occasionally performed to subdue violent behavior in some countries.

We have Phineas Gage to thank for, because his case revolutionized neurology – in good ways and in bad.

Causes of Myofascial Syndrome

By: Arvie Vitente, MPH, PTRP

Have you already experienced frequent cramping pain on your muscles mostly at the upper back area? That even with enough rest and massage the pain still persists? Maybe you are suffering from myofascial syndrome. Myofascial syndrome is included in the long list of chronic musculoskeletal pain disorder. In myofascial syndrome, there are palpable nodules in the muscles that are called the trigger points that cause pain upon application of pressure on them. This could also be felt in other parts of the body.

Causes of Myofascial Syndrome

Myofascial syndrome classically occurs among individuals with chronic faulty posture in which the muscles are contracting repetitively resulting initially to simple muscle soreness, then later on to a bothersome condition, which is the condition myofascial syndrome.

Clinically, the exact cause of myofascial syndrome is still not known. There is a theory associating it to connective tissue diseases but this is much generalized. Other theories state that this could be due to accumulation of lactic acid in muscles among individuals with jobs or other activities that require repetitive motions like in carpentry, typist, among others.

Another probable cause of myofascial syndrome are stress-related conditions. Individuals working in the academe are particularly prone to myofascial syndrome since aside from their true job, which is to prepare lessons and deliver these in their classes, they still have other school-related responsibilities which come with great pressure that would in turn result to muscle tension. Likewise, bank managers, typists and bus drivers are also prone to myofascial syndrome.

Difference between Myofascial Syndrome and Fibromyalgia

Myofascial syndrome and fibromyalgia both affect skeletal muscles but the difference is that, myofascial syndrome affects muscles on one side of the body that radiates on other parts, which include the neck and shoulder areas, while fibromyalgia affects muscles on a broader distribution.

Red Flags of Myofascial Syndrome

The signs and symptoms of myofascial syndrome may include deep, aching and cramping in the muscles involved. The description of pain in myofascial syndrome is usually pain that persists and is aggravating. The pain is elicited by applying pressure on the muscles affected which are called the trigger points. Patients with myofascial syndrome mostly complain of having a hard time to sleep primarily because of pain. If these symptoms are present, make an appointment with your doctor.

Treatment

Mostly, patients with myofascial syndrome are advised to undergo physical therapy and trigger point injections. Oral analgesics and relaxation techniques are also included in the treatment options.

How to Know If It’s Migraine: Be Aware of These Migraine Symptoms

Posted 29 Oct 2011 — by admin

Headache is probably the most common of all migraine symptoms. The question is, how will you be able to determine that what you are experiencing is really migraine? How are going to identify a migraine as compared to all other causes of headache?

Knowing the other associated migraine symptoms would help you differentiate migraine from headache caused by tension headache, sinusitis or cluster headache. If you are diagnosed with migraine, it is helpful to be familiar with such migraine symptoms so that you will be able to provide immediate care to decrease the pain that you are experiencing. Some migraines have auras, which are described as visual, olfactory or auditory perceptions that occur prior to a migraine attack. To be exact, auras may be experienced for 10-15 minutes before the occurrence of the actual migraine attack. Those who experience these auras describe them as flashes of light or visions of zigzag lines.

However, not all people who have migraine experience the auras mentioned above. In the absence of an aura, it is more integral to be familiarized with the different migraine symptoms. You will know if you are having a migraine if you experience any of the following:

  • Usually, one-sided headache. Although pain of both sides can also occur, this is less frequent than one-sided pain.
  • Throbbing type of pain. Intensity of this type of pain may range from moderate to severe. For most cases, the person will not be able to continue with his physical activity due to this debilitating intensity of pain.
  • Nausea or vomiting. Among the migraine symptoms, this is one of the most classic complaints of patients. They will say that the headache is accompanied by nausea and most patients say that they feel some degree of relief after they vomit.
  • Increased sensitivity to light, odors or noise.  The patient gets more easily irritated by these stimuli. That is why a person who suffers from migraine will prefer to rest on a dark and quiet place.
  • Other less common associated migraine symptoms such as pain near the eye, loss of appetite, blurred vision and dizziness

Remember, migraine is different from the other types of headache. These migraine symptoms described above are not commonly experienced by patients experiencing the other types of headache. Thus, you will be able to identify the difference. Now you would know, if it’s truly a migraine.

How to Prevent Delayed Onset Muscle Soreness When Exercising

Posted 29 Oct 2011 — by admin
Category Diseases and Conditions, Health Procedures, Keeping Healthy

Delayed Onset Muscle Soreness or DOMS is described as muscle pain that occurs 12-48 hours after the muscles were subjected to vigorous exercise. It can be more frequently experienced when you exercise at a particular intensity that the body is not yet used to, like when you initiate a new exercise regimen or when you progress your usual exercise to a heightened intensity or duration.

The reason why you experience DOMS is because of microscopic tearing of the smaller components of your muscles called muscle fibers. Aside from the tearing, swelling can also occur at the muscle fibers, causing you to experience muscle pain. Studies say that the greater the intensity of exercise, the greater will the microscopic tearing be, and so it also follows that the soreness of the muscles will be of a greater extent. There are studies that further say that eccentric or lengthening contractions of muscles are more likely to cause DOMS. Examples of activities that require eccentric muscle contractions are slowly lowering of weights after you have lifted it and the downward motion that you perform during squats and push-ups.

Although DOMS can largely cause discomfort, rest assured that it is a normal phenomenon. It is actually expected that when you subject the muscles to strenuous exercise, DOMS will eventually occur in a few days. However, there are measures that you can do to prevent the occurrence of DOMS. To avoid the discomfort of having that dull, aching type of pain days after you exercise, follow these three important measures:

  • Include a warm-up exercise for at least 10-15 minutes before your actual exercise regimen.

Gentle stretching of your muscles prior to your high intensity exercise can lower the tendency for you to experience DOMS. When you stretch prior to exercise, the muscles get more prepared for the actual exercise regimen.

  • Perform a cool-down exercise for at least 10-15 minutes after the actual exercise regimen.

Having a cool-down exercise after vigorous exercise, rather than suddenly stopping, can help in preventing the occurrence of DOMS. Cool-down can be in a form of gentle stretching or low-intensity activities such as walking or marching in place.

  • Progress your exercise gradually, not drastically.

With regards to progression of exercise, follow the ten percent rule. Progress the duration or intensity of your exercise only by ten percent a week. Also, be aware not to make sudden changes to your exercise regimen.

Different Stress Relievers That You Should Learn About

Most lifestyles today are full of deadlines, hectic schedules or quotas. That is why stress is a common experience for most of us today. The fact that some people consider stress as a natural thing is not a good idea. This is because, people might not be aware of how much stress is creeping into their systems and affecting their health. When stress becomes chronic without you doing anything about it, it may greatly affect your mental, physical and social health. This is why; stress relievers must be learned by you before stress takes its toll on your body.

Studies say that a large percentage of primary care consultation to physicians is due to stress-related issues. Come to think of it, these medical consultations could have been minimized if people know how to deal with stress on their own. If you think you are stressed now, you should learn some techniques that are known to be effective stress relievers. Do not let stress damage your health and well-being. You should do something about it now!

Find time to exit from the pressures of your daily routine. Try these different stress relievers and save yourself from the long-term adverse effects of stress.

  • Studies reveal that quiet reflection is one of the most effective stress relievers. This is done by stopping for a while, despite how fast paced the day is, and just think of thoughts that will be relaxing to you. It may be in a form of imagination of a serene place or reminiscing on a favorite memory. Studies further say that doing this for 10-20 minutes is the most effective duration that will help you relieve your stress.
  • Make a to-do list in chronological order based on the weight of priority of the tasks. To-do lists are also very effective stress relievers. Not only will they help you organize the things that you have to do, they will also decrease your tendency to mind-race. After you have listed the things that you should do in a day, cut your list into half. This means that you need only to do the “top priority tasks” in a span of one day.
  • Have a regular exercise regimen. Exercise helps your body to release the happy hormones called endorphins. These hormones are proven by many studies to reduce stress. In addition to this, endorphins cause a positive or euphoric feeling in the body that can help you have a renewed feeling of energy that will help you cope with the daily hassles that you will encounter.
