Insights

Retinopathy of prematurity (ROP) remains a leading cause of childhood blindness in Latin America. While screening and treatment have improved, wider implementation of national protocols and resources, potentially via telemedicine, is crucial for comprehensive coverage.

Area of Science:

  • Ophthalmology
  • Public Health
  • Neonatology

Background:

  • Retinopathy of prematurity (ROP) is a significant cause of blindness and visual impairment in Latin America.
  • Prevention, detection, and treatment of ROP have been regional priorities for the past 20 years.

Purpose of the Study:

  • To assess the progress and challenges in ROP screening and treatment across Latin America.
  • To identify areas for improvement in national protocols, legislation, and service delivery for ROP.

Main Methods:

  • Review of ROP screening and treatment initiatives in Latin American countries.
  • Analysis of national regulations and service availability in different provinces.

Main Results:

  • Progress noted in screening and treatment in about half of the countries with established ROP regulations.
  • Screening is not yet universally available in all provinces within most countries.
  • Significant gaps remain in national protocols, legislation, and human resource capacity.

Conclusions:

  • Continued effort is required to expand ROP prevention, detection, and treatment services nationwide.
  • Strengthening national frameworks and human resources is essential for universal coverage.
  • Telemedicine presents a promising strategy to overcome existing barriers and improve ROP care access.

Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Prevention of Further Absorption of Poison01:14

Prevention of Further Absorption of Poison

In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...

Preventive Healthcare Services

Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Pneumonia V: Nursing management and Prevention

Nursing management of pneumonia involves promoting airway patency, facilitating rest and conserving energy, encouraging fluid intake, maintaining nutrition, and educating patients.
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed....
