Clinical reasearches

Heart failure is a clinical syndrome resulting from structural and functional disorders of the myocardium of the heart. It can also result from diseases of the valves, endocardium, pericardium, rhythm, conduction disorders. It increases with age, with the frequency in individuals over 70 years old being over 10%. The lifetime risk by the age of 55 for the onset of heart failure is 33% in men and 28% in women.

One of the first symptoms is shortness of breath during exertion, meaning when patients cover some distance, they start to breathe heavily and need to stop or slow down. The same is true when climbing stairs. In people with heart failure, physical capacity decreases, they feel tired with certain physical efforts. Another symptom is orthopnea – people wake up at night feeling short of breath, and to breathe well, some of them use two to three pillows. Those suffering from heart failure also have swelling in the lower extremities.

COVID-19 is an acute respiratory disease caused by the SARS-CoV-2 virus. It can range from being asymptomatic to severe, with pneumonia and respiratory failure. The main symptoms include fever, cough, fatigue, loss of taste and smell, shortness of breath, and muscle and joint pain. The disease spreads mainly through airborne droplets and through contact with contaminated surfaces.

Anemia is a condition characterized by a reduced number of red blood cells or a decreased level of hemoglobin, leading to a reduced capacity of the blood to carry oxygen. The main causes include iron deficiency, vitamin B12 or folic acid deficiency, chronic diseases, and genetic disorders. Symptoms include fatigue, weakness, pale skin, and shortness of breath, and treatment depends on the underlying cause.

Type 2 diabetes is a chronic metabolic disease in which the body becomes resistant to insulin and the pancreas cannot compensate adequately. This leads to high blood sugar levels and an increased risk of complications such as cardiovascular disease, kidney problems, and neuropathy. The main contributing factors are obesity, genetics, and lifestyle. The disease is characterized by increased thirst, frequent urination, fatigue, blurred vision, slow-healing wounds, and infections.

Obesity is a chronic, multifactorial disease characterized by excessive accumulation of adipose tissue, which increases the risk of health complications and reduces life expectancy. Obesity is associated with an increased risk of type 2 diabetes mellitus, cardiovascular diseases, hypertension, certain types of cancer, osteoarthritis, and metabolic syndrome, and is considered a global public health problem.

Respiratory Syncytial Virus (RSV) is a common respiratory virus that causes mild symptoms similar to the common cold. Typically, individuals infected with RSV recover in about a week without requiring medical treatment. However, RSV can cause severe illness and death in infants under six months of age, individuals over 65 years of age, and people with compromised immune systems.

Each year in the EU, Norway, and the United Kingdom, RSV is responsible for hospitalizing approximately 213,000 children under the age of five and about 158,000 adults with some requiring intensive care. Every year, one in twenty elderly individuals in Europe becomes infected with RSV.

RSV affects different age groups differently but the most common symptoms of the disease include:

• Coughing
• Sneezing
• Fever
• Wheezing
• Hoarseness
• Sore throat
• Headache
• Nasal congestion
• Fatigue

Suppurative or purulent hidradenitis is a rare condition that affects the sweat glands in the areas of the armpits and groin, the anal opening, and under the breasts in women. It is characterized by red swellings, often painful or itchy, or with an unpleasant odour. Women and people aged 20-30 are more affected.

The development of the condition involves the blocking of hair follicles, but the exact causes are not specified. Experts believe it may be due to genetic predisposition, hormonal imbalance, smoking, or overweight.

Multiple sclerosis (MS) is a condition in which the myelin, the substance that insulates and protects the nerve cells of the brain and spinal cord, is damaged.
 

The damage disrupts communication between the nervous system and the rest of the body. In addition to myelin loss, there may sometimes be damage to the nerve fibres themselves, leading to increased disability that may occur over time.

The disease usually begins between the ages of 20 and 40 and is twice as common in women as in men. Symptoms of MS are highly varied and vary significantly among different patients, as well as at different stages of the disease in the same individual. Some MS patients may not develop symptoms for a varying period of time. Others experience 2-3 attacks per year. Symptoms can be categorized into several groups:

• Numbness and tingling;
• Pain and spasms;
• Fatigue and weakness;
• Balance and dizziness issues;
• Bladder and bowel dysfunction;
• Sexual dysfunction;
• Cognitive problems;
• Changes in emotional health.

Spondyloarthritis is a condition characterized by inflammation of the intervertebral joints of the spinal column. What sets it apart from other types of arthritic inflammation is that spondyloarthritis affects the areas where bones and ligaments connect.

In spondyloarthritis the facet joints rub painfully against each other between the individual vertebrae of the spinal column. Wear and tear in advanced age or overuse lead to the loss of the cartilaginous layer between the facet joints. Spondyloarthritis is also known as facet joint osteoarthritis or spinal osteoarthritis.

Those affected suffer from chronic back pain, especially after standing up or moving, i.e. whenever they load the spinal column.

The typical symptoms of spondyloarthritis depend on the strain on the back. About 15-20% of all patients with back pain have issues with facet joints. The first pain typically occurs in the morning immediately after getting up. This is because after a night’s rest, the spinal column sinks slightly under the weight of the body which needs to be moved and the painful and worn cartilaginous surfaces of the facet joints slide against each other. The lumbar spine area is most commonly affected. If spondyloarthritis is in the neck area the patient suffers from neck pain which may radiate to the shoulders, the back of the head, or even the upper back.

Bronchiectasis disease refers to the infection of bronchiectasis. In turn, bronchiectasis represents permanent enlargements acquired after damage to the muscular elements forming their walls.

The enlargement of the bronchi can be caused by congenital anomalies, bacterial infections and others. Common causes of the condition often include stress, social tension or isolation, unfortunate events such as loss of a relative, chronic illnesses, hormonal imbalance.

The disease is characterized by chronic cough accompanied by copious sputum often mixed with blood or pus. The condition can progress with alternating periods of exacerbation and remission.

Psoriatic arthritis (PsA) is a condition where the patient suffers from both psoriasis and arthritis. Like other forms of arthritis, PsA causes joint pain, stiffness, and inflammation, which can lead to irreversible joint damage.

Depending on the onset of skin psoriasis and arthritis, three courses of PsA are possible:

• Skin lesions appear first, with a varying period before the development of PsA – up to 20 years or more (usually around 10 years). During this period, only symptoms of psoriasis vulgaris are present.
• Arthritis appears before the skin changes.
• Rarely they occur simultaneously.

PsA is most common among the white race, with a gender distribution of 1:1 except for some subgroups of patients. The disease can debut at any time but most commonly between the ages of 20 and 50, with skin involvement usually preceding joint involvement.

Hypertension, also known as high blood pressure, affects many people, and the initial symptoms are often considered to be a result of another problem. These include intense headaches, ringing in the ears, difficulty falling asleep, and restlessness.

In hypertensive individuals, the pumping of blood is stronger, creating tension in the arteries and the risk of damaging vital organs. Arterial hypertension occurs when regular measurements reveal a persistent increase in both the lower and upper limits of blood pressure – above 90 mmHg for diastolic and above 140 mmHg for systolic.

The causes of hypertension can be other diseases or conditions, but in most cases, they are associated with improper diet, lack of physical activity, stress, and age.

The main symptoms of schizophrenia are in the realm of experiences, thoughts, and sensations. Among the early signs that indicate consultation with a specialist are significant changes in behaviour that cannot be explained by specific reasons—such as separation, death of a loved one, or bullying. This should always be a cause for concern. One of the most characteristic experiences is the feeling of loss of free will and a sense of submission to an external force or foreign will. An aspect of this experience is perceiving even one’s own thoughts as something external, dictated by another. Disturbances in perception in the form of auditory and sensory hallucinations are commonly encountered in this condition.

Paranoid fears are another important sign of schizophrenia. It is believed that it is not the disease itself that is inherited, but the predisposition to it. Therefore, schizophrenia is not a classical hereditary condition. If one parent suffers from the condition, the likelihood of the child becoming ill is around 15%, but if both parents have this problem, the probability increases to 30%. There are other factors that have not yet been sufficiently identified, and if they are investigated, it will improve prevention in the family or school environment. Specialists define family relationships as a very important factor.

Also known as nettle fever, urticaria is a skin rash characterized by raised, itchy welts. In more severe cases, angioedema may also occur.

There are two forms of urticaria: acute and chronic, which are more common in women. The most common form is acute, which typically resolves within 6 weeks in 95% of patients. Symptoms of chronic urticaria persist for a longer duration.

Triggers for urticaria can vary widely and include: foods, medications, infections, underlying medical conditions, low air temperature, hot water, sun exposure, and others.

Depression is a common disorder characterized by a wide range of emotional, cognitive and physical symptoms. These symptoms affect everyday life. People with depression have little control over their mood and emotions and feel consistently down. As a result, they may struggle to maintain their job, continue their education, and/or sustain their family and social relationships.

Depression can affect anyone but various social and biological factors can increase a person’s risk of developing the disorder. Additionally, stressful experiences such as illness, unemployment, or significant loss can trigger the onset of the condition in some individuals.

Depression may occur once in a lifetime but it is typically an episodic disorder. During these episodes symptoms occur for most of the day, nearly every day and may include:

• Feelings of sadness, crying spells;
• Outbursts of anger, irritability or a generally bad mood most of the time;
• Difficulty falling asleep or excessive sleeping;
• Significant change in appetite, often with weight gain or loss;
• Fatigue and lack of energy;
• Feelings of worthlessness, self-blame and guilt;
• Difficulty concentrating on everyday activities;
• Slowed or restless movements;
• Unexplained physical problems such as back pain or headaches;
• Withdrawal from usual activities and social interactions;
• Feelings of hopelessness or emptiness;
• Frequent or recurring thoughts of death, suicidal thoughts, suicide attempts;
• Loss of pleasure in activities that usually bring happiness – sports, hobbies, including sexual activity.

Chronic Obstructive Pulmonary Disease (COPD) is among the lung diseases characterized by partial or complete restriction of airflow. It results from inflammation of the lung tissue due to inhaling gases and particles from the air.

It can manifest as chronic bronchitis or as pulmonary emphysema. A primary risk factor for the disease is smoking. Those affected are mainly men around the age of 50 who are smokers.

Symptoms typical of COPD include coughing, breathlessness, chest tightness, and phlegm production, among others. Periods of exacerbation may alternate with symptom-free periods.

Alzheimer’s disease with psychosis is a condition characterized by memory loss and cognitive impairment. As the frequency of Alzheimer’s disease continues to rise, efforts in medical science to discover the cause of the disorder are increasing as well.

The disease is known as a complex “multifactorial” disorder. This means that while scientists are not sure exactly how Alzheimer’s disease begins, they believe it is caused by environmental circumstances combined with genetic factors.

Everyone experiences episodes of forgetfulness from time to time. But people with Alzheimer’s disease display certain persistent behaviours and symptoms that worsen over time. These may include: memory loss affecting daily activities, such as keeping appointments; problems with familiar tasks, such as using a microwave; difficulty solving problems; speech or writing problems; disorientation in time or place; decreased judgment; decreased personal hygiene; mood and personality changes; withdrawal from friends, family, and community. Symptoms vary depending on the stage of the disease.

Anxiety is a normal reaction that occurs in response to stress. Sometimes, however, people experience reactions of fear and anxiety that are triggered without any threats or they may perceive the threat as more dangerous than it actually is. For people struggling with anxiety, their fear and worry interfere with their ability to function and compromise their ability to enjoy life. Fortunately, there is plenty of support and numerous treatment options available for managing anxiety.

Anxiety can manifest in various forms, such as generalized anxiety, panic attacks, obsessive-compulsive disorder, phobias and others.

Ulcerative colitis can affect different segments of the gastrointestinal tract. Because symptoms and complications in patients with this condition can vary depending on the type and severity of the disease manifestation, it is important for these patients to know the type of ulcerative colitis they have been diagnosed with and how it will affect them.

The disease usually begins with abdominal pain and swelling, followed by spasms and bleeding. Diarrhoea is particularly characteristic, occurring up to 40 times a day in its acute phase and often accompanied by bloody and mucous discharge. The affected person experiences constant urge for defecation.

In addition to being very distressing, this causes the body to lose fluids, vitamins and minerals. This results in deficiencies of nutrients, especially proteins, calcium, iron, folic acid, vitamin D, and B12.
Deficiencies provoke additional symptoms: weight loss, anaemia, susceptibility to infections, exhaustion. Less commonly eye irritation, joint pain and rashes on the body may occur. In severe cases, paralysis of the colon may occur.

Asthma is a long-term condition that causes inflammation of the airways. The inflammation and swelling of the airway wall lead to narrowing of their lumen.

Because of this inflammation, the muscles around the airways become more sensitive to various irritants. This can cause their contraction and also lead to narrowing of the bronchial tubes’ lumen, making breathing difficult. The smaller the diameter of the airways, the harder it is to breathe. More mucus may also be produced, which further obstructs breathing by accumulating in the bronchial tubes’ lumen.

The condition is characterized by recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, triggered by nonspecific irritants (toxic gases such as sulphur dioxide, nitrogen dioxide, ozone, dust, cold air and odours).

The severity of asthma attacks varies from mild to life-threatening. The characteristic feature of asthma is that the attacks are periodic.
