Summary
Online sun protection advice is often low-quality and may be influenced by commercial interests. This study highlights the need for reliable, evidence-based information on sun exposure risks and benefits.
Area of Science:
- Dermatology
- Public Health
- Health Communication
Background:
- Rising rates of ultraviolet (UV)-induced skin damage necessitate public health emphasis on safe sun exposure.
- Promoting moderate sun exposure and effective sun protection is a key public health objective.
Purpose of the Study:
- To evaluate the quality and nature of online information regarding sun exposure effects and protection strategies.
- To assess the reliability of web-based resources for sun safety advice.
Main Methods:
- Searched French-speaking web using eight search engines and terms to find sun protection websites.
- Compared website information against recommendations from nine official health organizations.
- Assessed website quality based on four criteria: risks/benefits of sun exposure, sun avoidance, clothing, and sunscreen use.
Main Results:
- 129 relevant web pages were identified from 1551 initial links.
- Most websites provided deficient information on sun effects and protection compared to official guidelines.
- Higher quality websites and those without commercial links generally offered better advice, except for sunscreen recommendations.
Conclusions:
- Web-based resources for sun protection advice on the French-speaking internet have significant limitations.
- The poor quality of many websites and potential conflicts of interest with sunscreen manufacturers contribute to these deficiencies.

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

01:23Role of Skin in Vitamin D Synthesis
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).

01:10PPE Use in Healthcare Settings II: Doffing
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.
01:25Transmission-based Precautions II: Airborne and Protective Environment
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...
