Cancer Prevention02:59

Cancer Prevention

7.7K
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.

Prevention of Further Absorption of Poison01:14

Prevention of Further Absorption of Poison

1.2K
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

1.9K
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:

Pneumonia V: Nursing management and Prevention01:30

Pneumonia V: Nursing management and Prevention

3.5K
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....

Healthcare Associated Infections II: Preventive Measures

3.6K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Production of Formed Elements01:34

Production of Formed Elements

3.6K
Hemangioblasts are multipotent stem cells originating from the mesoderm. They give rise to hematopoietic stem cells (HSCs), which undergo hematopoiesis to produce all the formed elements of blood. This process is regulated by a complex network of hematopoietic growth factors, including transcription factors, growth factors, and cytokines. These factors stimulate the HSCs to divide and differentiate, though some HSCs remain undifferentiated to maintain a self-renewing pool.
Most HSCs commit to...

Area of Science:

  • Pharmacology
  • Infectious Diseases
  • Drug Delivery Systems

Background:

  • Systemic pre-exposure prophylaxis (PrEP) for HIV and STIs has limitations.
  • Topical inserts offer a localized alternative for mucosal drug delivery.
  • These inserts can be formulated for rapid or sustained release of antiviral agents.

Purpose of the Study:

  • To review the development and potential of topical inserts for STI and HIV prevention.
  • To explore end-user preferences and formulation considerations.
  • To assess the clinical viability and future impact of this novel dosage form.

Main Methods:

  • Review of existing literature on topical insert technology for STI/HIV prevention.
  • Analysis of formulation options, including fast-dissolving and slow-release systems.
  • Examination of end-user acceptability studies and clinical trial data for placebo prototypes.

Main Results:

  • Topical inserts provide targeted drug delivery to mucosal surfaces, reducing systemic exposure and side effects.
  • They are user-friendly, discreet, portable, economical, and stable.
  • Early clinical assessments of placebo prototypes indicate feasibility.

Conclusions:

  • Topical inserts represent a highly promising dosage form for HIV and STI prevention.
  • Further research and development are warranted to optimize formulations and assess efficacy.
  • This technology has the potential to significantly impact the HIV prevention landscape.
