Cancer is the second leading cause of death worldwide which is responsible for an estimated 9.6 million deaths in 2018.¹

Breast cancer ranks as the second most common cancer and the fifth most common cause of deaths due to cancer globally.^{2, 3, 4, 5} In Malaysia, this disease has accounted for 34.1% of all cancer among the females.⁶        

Breast cancer can occur at different parts of the breast like the lobules, ducts and connective tissue. The lobules are the milk producing gland, the ducts are tubes that allow milk to reach the nipple and the connective tissue which consists of fibrous and fatty tissues surrounds and keeps everything together. Breast cancers most commonly occur in the ducts or lobules.^{4, 7}    

Different people experience different symptoms of breast cancer and some does not experience any signs and symptoms at all.⁸ Some of the warning symptoms are changes in the shape or size of breasts, presence of lump in the breasts or underarm areas, changes in nipples (appearance of nipples, pointing direction or presence of any clear or blood discharge), swelling of part of the breast, dimpling or irritation on the breasts skin area, redness, rash or eczema on breasts skin and nipples area, continuous pain in any area of breast, nipples or axilas.^{4, 8, 9, 10, 11}

Breast cancer risk increases with age and a majority of those diagnosed are post-menopausal. Other factors that increases the risk of breast cancer include being a female, inherited genetic mutation, first pregnancy at a later age, low parity, early menarche, late menopause, having dense breast, being overweight or obese in post-menopausal women, physically inactive, previous history of radiotherapy to the breasts and drinking alcohol.^{9, 12}

Breast cancer screening examines a vast number of asymptomatic individuals to identify positive cancer cases and to prevent deaths due to breast cancer by detecting the cancer at an early stage when treatment will be more effective. The cancer can be controlled by early detection through routine self-breast exams, mammographic screening, reducing prevalence of known risk factors and improved treatment.^{4, 5, 9}

Atherosclerosis is a chronic inflammatory disease caused by build-up of plaque inside the arteries.^{1, 2, 3}  This disease is a major contributor of cardiovascular diseases (CVDs) and has an increasing prevalence globally each year.^{2, 3, 4} 

The chronic build-up of plaque (fatty deposits) in the artery wall causes blood vessel thickening and arterial stenosis (narrowing of artery wall). The narrowing within the artery channel will result in blood flow restriction, thereby, leading to tissue hypoxia.^{5, 6, 7, 8}

Immune activation was identified in the atherosclerotic plaque where inflammatory cells are attracted within the arterial wall and into the atherosclerotic plaque, hence, promoting the progression of atherosclerotic lesions.^{2, 6, 7, 8}

Signs & Symptoms

Atherosclerosis usually does not manifest any signs and symptoms until an artery is severely narrowed or blocked. Many people will only get to know they have the disease when a medical emergency such as a heart attack, unstable angina pectoris or stroke occurs.^{9, 10}

Some individuals may have signs and symptoms of the disease which depends on which arteries are affected.¹¹

Risk Factors

Atherosclerosis is a slow and complex disease which may develop in childhood and progress as a person ages.^{5, 11}

Some common factors that cause damage to the inner lining of the arteries which will lead to atherosclerosis to take place are smoking, high blood pressure, being overweight or obese, oxidative stress (reactive oxygen species), high blood cholesterol, high blood glucose levels, family history and lack of physical activities.^{5, 11, 12, 13}

Diagnosis

A medical practitioner will diagnose atherosclerosis based on the patient’s medical and family histories, physical examination and test results.^{5, 14}

Blood Tests

A blood test is done to measure the levels of certain fats, cholesterol, glucose and proteins (biomarkers) in the blood. Abnormal levels of these parameters may be a sign that a person is at an increased risk of developing atherosclerosis.^{5, 14}

Electrocardiogram (ECG)

An ECG is a simple and painless test that detects and records the electrical activity of the heart. The test can detect signs of a previous or current heart attack.^{5, 14}

Echocardiography

An echocardiography test shows the size and shape of the heart and how well the heart chambers and valves are functioning. The test can also identify poor blood flow areas of the heart, areas of heart muscles that are not contracting normally and previous injury to heart muscle due to poor blood flow.^{5, 14}

Exercise Stress Testing

During a stress test, the patient is required to exercise and make the heart work hard and beat fast while the heart tests are performed. Arteries that are narrowed due to plaque build up do not supply adequate amounts of oxygen-rich blood to the heart, hence, a stress test indicates possible symptoms of a coronary artery disease.^{5, 14}

Angiography

An angiography test is done to observe the inside of the arteries by using dye and special x-rays. This test can show whether the arteries are blocked by a plaque and how severe is the blockage.^{5, 14}

Computer Tomography (CT) Scan

A CT scan can show if an artery is hardening or narrowing.  The test can also indicate when there is calcium build up in the walls of the coronary arteries which is an early sign of a coronary artery disease.⁵

————————————————————————————————————————

Screening for asymptomatic atherosclerosis is important for an early diagnosis as an efficient strategy to control risk factors and prevent or delay atherosclerosis and its related diseases. It is also crucial to identify patients that require long-term surveillance, medication or surgery.^{5, 15, 16}

Food Allergy

Food allergy is a  serious public health issue with an increasing prevalence that affects both the children and adults.¹ It occurs when the body has a specific and reproducible immune response to certain foods which can be severe and life-threatening (anaphylaxis).² This disease is also associated with an increased morbidity, affecting the daily quality of life.³    

Symptoms   

The symptoms and severity of a food allergy reaction can be different between individuals and for one person over time.²

Around 15% of young children and 3% of adults in Malaysia have developed allergy symptoms during their early childhood.^{4, 5} Food allergy reactions usually include the three main systems which are the digestive system, skin and respiratory system.⁶ The most common symptoms are allergic rhinitis, diarrhea, eczema and asthma, whereas, less common manifestations are infantile colic, chronic diarrhea, reflux of stomach contents, failure to thrive in children and anaphylaxis.^{4, 6} In some individuals, allergic reactions to food are mild but some may experience severe reactions that can result in death.⁶

Causes

An individual is more likely to develop food allergy when someone in the family has allergies (genetic disposition) or when certain foods trigger the allergic reactions. Among the common foods that often induce allergic reactions are eggs, legumes, nuts, seafood, shellfish, milk, soy, cereals (wheat, oats, barley, corn), fruits (apple, bananas, kiwi, avocado, papaya, etc.) and vegetables (potato, carrot, celery, etc.).^{2, 6}

Diagnostic Tool

The most common diagnostic tests to evaluate IgE- mediated food allergy are skin prick test (SPT) or blood test specific IgE to allergens. ^{7, 8}

The table below summarises the comparison between blood test which measures specific IgE to allergens and skin prick test.
