From Concept to Market: The Drug Development Timeline

From the initial idea that a chemical compound could become a drug until the molecule is ready for marketing, the process typically spans about seven to twelve years.

Sources of Medicinal Compounds

Chemical defenses from fungi and and plants against viruses and bacteria are significant sources of drugs. The contribution of the marine world has achieved a high profile, exemplified by AZT for AIDS, which was extracted from herring sperm. The plant kingdom is a paradise for pharmacology. Animal-derived medicines are also obtained; for instance, insulin was first extracted from the pancreas of a dog.

Sometimes, medicines designed for one objective prove... Continue reading "Drug Discovery & Development: From Lab to Market" »

Effective Negotiation Strategies and Tactics

Strategies to handle challenging scenarios: change of subject, avoiding the false lure, guilt, sphinx, broken record, judo, bulldog, break, and limited resources.

Item

Weaning

Weaning is the introduction of foods other than breast milk.

Steps for the Development of Food

• Period of 6 months of exclusive breastfeeding.
• The transition period between 4–8 months.
• Modified adult diet period between 6 and 12 months.

Recommendations

• Start no earlier than 4 to 6 months.
• Start with porridge.
• Use familiar staples.
• Start with one food at a time.
• Combine foods only after tolerance is established.
• At the end of the year, simply chop the food.
• Do not add salt, sugar, honey, or butter.
• Remove the bottle around 13 months.
• Offer the child the same food for at least 5 days.
• Gradually increase the amount of food (tablespoons).
• Adjust feeding times to the family schedule.
• Consider the family's allergic history.

Anthropometry

• Anthropometric evaluation

Surgical Treatment: An Overview

The term surgical treatment, or surgery, is very broad. It can be classified into major surgery and minor surgery:

• Major surgery involves significant procedures, such as an appendectomy or cardiac intervention. Due to its importance and complexity, it can lead to serious post-operative complications. Patients often need to remain in the hospital for some time to be monitored and treated by medical personnel.
• Minor surgery includes simpler, short-duration interventions performed on superficial and accessible tissues, for example, wart removal. Generally, the number of complications is low.

Today, thanks to significant progress in surgery, some surgical procedures that traditionally required hospitalization can now... Continue reading "Understanding Surgical Treatments: Types, Risks, and Innovations" »

Respiratory Diseases

Respiratory diseases affect the lungs and airways, impacting breathing and overall health. They can be caused by various factors, including bacteria, viruses, and environmental irritants like tobacco.

Bacterial Respiratory Infections

These conditions are caused by bacterial pathogens and can range from mild to severe.

Sinusitis

Sinusitis is an inflammation of the lining inside the bones that are in contact with the nasal passages. Symptoms include pain over the eyebrows and forehead.

Pharyngitis and Tonsillitis

Pharyngitis is a diffuse inflammation of the pharynx. If the inflammation is located in the tonsils, it is called tonsillitis. These conditions may be caused by microbes, cold air, and irritants such as alcohol and tobacco,... Continue reading "Understanding Respiratory Ailments and Tobacco's Effects" »

Physical Growth and Motor Development Stages

Defining Physical Growth

Physical growth refers to the measurable physical changes and biological processes that occur in the body throughout the lifespan. Understanding these changes is crucial for assessing overall health and development.

The key phenomena that define physical growth are:

• Increased body size
• Changes in body proportions
• Body composition changes
• Changes in functional complexity
• Achievement of physical fullness (maturity)

Stages of Human Growth and Development

Human growth is typically divided into the following periods:

1. Prenatal Period (Conception to Birth)
2. Early Childhood (2 to 5 years)
3. Middle Childhood (Up to 10–11 years)
4. Puberty (12–14 years)
5. Pre- and Adolescence (15–18 years)
6. Youth/Young

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

Why Inform a Patient of Their Diagnosis?

Why is there a tendency to inform the patient of their diagnosis? To settle outstanding issues that can be reconciled with certain persons and to take advantage of the rest of their life.

Stages of Acceptance of Death

Stages of acceptance of death: Denial, anger, bargaining, depression, and acceptance.

What Serves as the Negation of Illness?

What serves as the negation of illness? It is a defense mechanism to give time and to assimilate the new situation.

What Negotiations May Have a Religious Character?

What negotiations may have a religious character? Religious (rites, vows, sacrifices), magic (healers), or supernatural force.
