Heart printed in 3D can leave surgeries safer

Heart printed in 3D can leave surgeries safer

3D printing enables the creation of biomodels, which reproduce all the details of the anatomy of the patient's organ, collaborating with medicine and allowing physicians to diagnose more accurately, having a more detailed preparation in surgeries.

According to the experiences of previous surgeries, the technique allows the surgeon enter precisely the idea of ​​what you will find. "The image can be perfect and give a good idea of ​​what we will find, we have evolved a lot because of the image. But the fact of perceiving the organ three-dimensional, placing the hand and seeing under all the positions brings a contribution much greater than the image alone, "says surgeon Luiz Antonio Rivetti, a professor at the Santa Casa School of Medical Sciences and a researcher.

Left ventricular aneurysm, studied by researchers, may occur due to an acute myocardial infarction or Chagas. According to Leila, the surgery would be indicated to patients who already have sequelae due to the malfunction of the heart muscle, which can dry it, making it stop working. Remodeling the heart would make it work correctly again.

Leila explains that in order to perform the tactic, the surgeon must know precisely which portion of the muscle does not contract more. In this way, the replica would be included, which reproduces the heart at the exact moment of the contraction of the organ, showing the details of the region that did not contract properly. "When the biomodel is used, the surgeon will already plan and imagine how much to be able to dry up in surgery.He gave the surgeon a greater security so that we can go more smoothly in the procedure, "explains Rivetti.


Zika: rapid test is developed in Brazil

Zika: rapid test is developed in Brazil

Agência Brasil - The Health Secretariat of Bahia obtained the registration of the National Agency of Sanitary Surveillance (Anvisa) and presented today (31) in Salvador , the first national rapid serological test to detect the Zika virus. The health secretary of Bahia, Fábio Vilas-Boas, points out that the rapid test will make life easier for the population by allowing women, for example, to know if you have ever been or are infected with the virus.

Better oral hygiene could reduce the risk of pneumonia

Better oral hygiene could reduce the risk of pneumonia

New research from Yale University School of Medicine found changes in oral bacteria preceding development of pneumonia in hospitalized patients. Samit Joshi, MD, chief of the study, concluded that changes in oral bacteria may influence a person's risk of developing pneumonia after studying 37 participants within a month.
