Overnutrition and Obesity: Definitions and Causes

Overnutrition: a type of eating disorder caused by excessive intake of food as usual, which is higher than the nutritional needs of that person.

When is a person obese? A person is obese when body weight exceeds the normal by 20% or more.

Other factors in obesity: is due to hereditary factors (genetic), endocrine (glands in these disorders), metabolic or environmental (chemical reactions that occur in our cells).

Complications involved in obesity: hypertension, increased cholesterol, diabetes, myocardial infarction or stroke (overnutrition)...

Cancer: Uncontrolled Cell Growth and Modern Approaches

Understanding Cancer Development

Under normal conditions, our body's cells are replaced at a proper rate. Sometimes, however, cells grow out of control and are unable to specialize and perform their corresponding functions. This uncontrolled growth causes a tumor. Some tumors are small and do not cause problems, but others grow quickly and destroy surrounding healthy cells; these are malignant. When malignancy progresses, the cells can spread throughout the body, i.e., metastasize, via blood vessels and the lymphatic system. Uncontrolled cell division can lead to malignant tumors, causing the disease known as cancer.

Workplace Risk Management and Protection

Employers are responsible for controlling occupational risks and implementing preventive and protective measures. Prevention measures aim to avert the materialization of occupational hazards. Protection measures, conversely, act by controlling damage, seeking to eliminate or minimize its impact. Prevention measures are classified as:

Organizational Prevention Measures

1. Staff Selection: This allows for the identification of candidates with the appropriate knowledge for the workplace, ensuring proper use of equipment and procedures.
2. Training and Information: These enable workers to identify risks associated with their jobs and apply learned techniques to avoid them.
3. Medical Control: Achieved through periodic

Pharmaceutical Research and Drug Development

6.1 Development of Medicines: Stages and Trials

The process of developing new medicines is typically divided into two main stages:

Stage 1: Discovery and Preclinical Trials

• This stage involves searching for substances that exhibit therapeutic activity against a disease while possessing minimal toxicity. This process is known as screening.
• Selected substances are subjected to in vitro tests. The most active candidates then undergo tests on animals to assess their response, efficacy, and safety profile.

Stage 2: Clinical Trials and Drug Safety Testing

The primary goal of this stage is to test the safety and efficacy of drugs in human subjects. It is conducted in four standard phases:

1. Phase I: Reviews safety

Common Kidney and Urinary System Disorders

Glomerulonephritis

Glomerulonephritis is an inflammation that affects the glomeruli. It is typically caused by an immune reaction to a toxin released by streptococcal bacteria, which has infected another part of the body, usually the pharynx (throat). As a result, the urine contains many red blood cells and large amounts of protein.

Pyelonephritis

Pyelonephritis is an inflammation of one or both kidneys, affecting the nephrons and the renal pelvis.

Cystitis

Cystitis is an inflammation of the urinary bladder wall, usually caused by bacterial infections. The most common symptoms include a burning sensation during urination, urgency, and frequent urination.

Nephrotic Syndrome

Nephrotic Syndrome is characterized...

Type 1 Diabetes Treatment and Insulin Therapy

The symptoms of Type 1 diabetes are caused by a problem in the production of insulin. Treatment consists of delivering this hormone directly, which must be done daily to ensure continuous glucose regulation.

Glucose Regulation Mechanisms

The body has regulatory mechanisms that constantly control the balance between glucose and insulin levels. There is a hormone antagonistic to insulin, glucagon, also secreted by the pancreas, which acts when glucose levels are too low.

Monitoring Blood Glucose

Glucometers are used to measure glucose from a drop of blood.

Biotechnology in Diabetes Management

Recombinant Insulin

Recombinant human insulin is produced using genetically modified bacteria.

Defining Disease and Pathology

The WHO defines disease as the state in which the social, intellectual, emotional, physical, or spiritual development of a person is reduced or altered compared to their previous normalized experience. If the person is conceived as a disease, it is the lack of harmony between the elements that constitute them.

How Disease is Managed

Pathology is the science of disease. Diagnosis is the foundation that allows us to anticipate events that can happen, design a treatment plan to correct the disease, and determine actions to achieve clinical objectives.

Clinical Tools for Diagnosis

Clinical studies analyze the signals that reveal the disease using three types of tools:

• Signs: These are the objective data obtained from the

The Major Challenges in Organ Transplantation

A transplant is the replacement of a diseased organ, which endangers a person's life, with a healthy one that functions properly. It's not always necessary to replace the entire organ; sometimes, a part of the organ, or even just some tissue or cells, is sufficient.

The therapeutic method of transplanting organs and tissues faces three major problems:

1. Immunological rejection
2. The shortage of available organs
3. The technical impossibility of obtaining certain organs or tissues

Immunological Rejection

Our immune system has the ability to distinguish between 'self' and 'non-self.' When white blood cells detect something foreign, they attempt to destroy it. This response is crucial when the foreign entity is...
