Impact of climate change on the geographical distribution of ticks of public health significance in Colombia: Amblyomma ovale (Ixodida: Ixodidae), the Amblyomma maculatum (Ixodida: Ixodidae) complex and the Amblyomma cajennense (Ixodida: Ixodidae) complex.

Article Synopsis
- Ticks from the Amblyomma genus in Colombia, including the complexes A. maculatum, A. cajennense, and A. ovale, are known to transmit Rickettsia species, but their distribution is not fully understood.
- Predictive models showed that A. ovale and A. maculatum may expand their range by 2070, while A. mixtum and A. patinoi might see a decrease in their distribution; factors like temperature and rainfall significantly influence these changes.
- Ongoing surveillance is essential to study the potential spread of rickettsiosis related to different Rickettsia species across these tick populations and their environments.
Background: The effectiveness against radiation of tungsten bismuth caps, used in interventional cardiology is not well known.
Aim: To determine the degree of radiation protection conferred by these caps in real work conditions.
Material And Methods: We compared the gross electric charges received at brain lobe levels by three occupationally exposed professionals who participated in 22 consecutive procedures, inside and outside of the tungsten bismuth cap.
Point-of-care detection is a widely studied area that attracts effort and interest from a large number of fields and companies. However, there is also increased interest from the general public in this type of device, which has driven enormous changes in the design and conception of these developments and the way data is handled. Therefore, future point-of-care detection has to include communication with front-end technology, such as smartphones and networks, automation of manufacture, and the incorporation of concepts like the Internet of Things (IoT) and cloud computing.

Aim: To assess if the degree of attenuation of the secondary ionizing radiation achieved by the use of 0.
