The Risk Factors of Coronary Heart Disease.

Coronary heart disease (CHD) is one of the most common diseases to affect the heart. It is usually caused by atherosclerosis, which is a build up of fatty materials within the walls of the arteries.

There are many known risks of coronary heart disease. Although some of these factors are out of your control (age, gender and family history of CHD), there are some that you CAN control. These include:

• High blood cholesterol and triglyceride levels (triglyceride is a type of fat found in the blood).
• High blood pressure
• Diabetes
• Being overweight or obese
• Smoking
• Lack of physical exercise
• Unhealthy diet
• Stress

Many people have at least one CHD risk factor. Your risk of CHD and heart attack increases with the number of risk factors you have and their severity. Additionally, some risk factors will put you at greater risk of CHD and heart attack than others. Smoking and diabetes are prime examples of such factors.

Many CHD risk factors start during childhood. This is becoming more and more common nowadays because many children are overweight due to an unbalanced diet and lack of exercise.

Coronary heart disease is the biggest killer in the UK, causing approximately 94,000 deaths every year. On average, people at low risk of CHD live nearly ten years longer than people at high risk of CHD.
However, there are ways that you can reduce the risk of developing CHD. These approaches include:

1. Not smoking
2. Maintaining a healthy weight
3. Lowering/controlling your cholesterol
4. Exercising regularly,
5. Eating less saturated fat, more fibre and avoiding trans fats
6. Managing stress effectively

If you already have CHD, adopting some of these approaches might well reduce the severity of your symptoms.

Benign and Malignant Tumors-what is the difference ?

As part of my preperation for applying to medical school this coming year, I have been researching the differences between benign and malignant tumours, and this is what I have found.

Malignant tumors are invasive. They tend to invade and start growing in surrounding tissues . They can be very fast growing and can kill. They may also spread to other parts of the body (metastasis) through the blood stream & the lymphatic system. A common example of  a malignant or cancerous tumour is breast cancer. If a malignant tumor has spread and cannot be completely removed by surgery, then chemotherapy or radiotherapy, or a combination of both is often required. Chemotherapy & radiotherapy may also be used where the malignant tumour appears to have been removed completely to prevent recurrence at the same site or spread to other parts of the body.

Radiation therapy can last from 3-6 weeks and is used to kill the cancer cells and so reduces the size of the tumor. The genetic material of the cell is destroyed making it impossible for that cell to divide. However, this can cause short or long term effects. Skin soreness, nausea and tiredness may be caused, and long term effects may be shrinking of breasts and tiny broken blood vessels may leave marks on the skin.

Chemotherapy is used to damage the DNA of the cell and affects therefore the growth and the proliferation of the cell. Chemotherapy slows down the growth of any tumour cells. Chemotherapy drugs attack rapidly growing cells, however this might not just be cancer, the drugs can interfere with normal dividing cells too, such as cells in the blood, nails, hair and nose. The normal cells can repair themselves after treatment.

Benign tumors are not invasive. They have well defined boundaries and therefore do not invade surrounding tissues. They are slow growing and will not usually kill. Benign tumors can often be left where they are as long as they are in a safe place and are not affecting the function of surrounding organs, however otherwise they can be removed surgically and the patient should then recover.

Faecal Occult Blood Tests | FOB test kit | Faecal Occult Blood Screening | Bowel cancer screening

Screening for faecal occult blood (FOB) is an established method of population screening for bowel cancers and pre-cancerous conditions such as polyps and inflamation. It is important to understand the test is not specific for cancer diagnosis. Screening tests must have a high specificity and sensitivity to offer accurate indicators for further diagnostic investigation. The FOB test kit is designed to screen asymptomatic populations for bowel cancer. Those with symptoms should consult their doctor.

The faecal occult blood tests work by detection minute amounts of blood present in the stool as a consequence of the underlying condition, which would not normally be evident on routine examination or be apparent to the patient.  The traces can be detected well before other symptoms become apparent, making faecal occult blood screening a useful tool in well person population screening.

Bowel cancer is the third most common cancer in the UK and the 2nd commonest cause of cancer deaths, affecting up to 1:20 of the general population and 37, 000 patients a year in the UK. Recently population faecal occult blood screening services have started to be offered by the NHS  to 60-69 year olds every 2 years via GP community services. The FOB screening test is also commonly included in private health screeing programmes on a 2 yearly basis and is also available in home / self test kit formats

Pick up rates in the 60-69 year age band stand at approximately 2% per year, and confirmed positive results are referred for specialist colonoscopy investigation and diagnosis, of these half are normal, 40% will have polyps which can be treated during colonoscopy and 10% will have a cancer diagnosis and require specialist management. The FOB tests are not 100% accurate, but population faecal occult blood screening has been proved effective at reducing mortality (death) rates in the 60-69 year age band, if performed every 2 years.

The latest Laboratory point of care Faecal Occult Blood Tests incorporate test membranes that meet exacting CE IVDD quality standards for professional diagnostic biotech products such as the Mission FOB 50 test packs. These offer professional test kits accurate, highly cost effective, faecal occult blood screening.

An introduction

Hi I am a new blogger to this site and will be known as medschool2013.

 I am currently studying for my A-Levels and a prospective medical student applying in October 2012. I have a huge passion for medicine with particular interests currently being in the branch of cardiology. This interest was ignited during my work experience placement shadowing doctors in a cardiology department. Since then i have pursued my interest by undertaking an Open University module ‘Understanding Cardiovascular Diseases’. As well as this I try to play an active role in my local hospital as I am a member of the NHS youth council.

I hope my blogs will be interesting, engaging and intriguing to everyone and I will appreciate any feedback/suggestions.

Ovulation and the LH surge

Ovulation

Ovulation is the release of an egg from the ovary. The egg then travels into the fallopian tube where it is ready to be fertilized. In order for conception to occur, the egg must be fertilized by sperm within approximately 24 hours of its release from the ovary. This is quite a short window of time and is known as the ‘fertile time’.

The LH surge

Immediately prior to ovulation,  the body produces a large amount of luteinizing hormone (LH) which triggers the release of a ripened egg from the ovary. This “LH surge” usually takes place in the middle of the menstrual cycle. Ovulation prediction kits or OPK’s as they are known for short detect the LH surge in urine, signalling that ovulation is likely to occur in the next 24-36 hours. Ovulation prediction tests help you predict the time of ovulation, and peak fertility.  It is during this fertile time that conception is most likely to occur.

An Introduction

Hi everyone it’s Futuremedic1 here!

I am a new guest blogger on this site and I thought I’d tell you all a little about myself. I’m a prospective medical student who is hoping to go to medical school next year (2013). My current interests in medicine lie in the fields of oncology and cardiology, although of course that is liable to change as I explore other branches of medicine. As for work experience, I have undertaken a couple of weeks in my local hospital and have also spent time at a scientific research lab. I hope that you will read and enjoy my posts, and please feel free to ask me any questions.
