Impact of new Health technology to the Public

Notable advances in biology as the structural model of deoxyribonucleic acid (DNA), the methods for determining the sequence of the nitrogenous bases in DNA, the invention of the PCR reaction (Polymerase Chain) and the Genome Project People have improved understanding at the molecular level, the pathogenesis of various chronic and communicable diseases, as well as understanding how biological factors are determinants of health in this sense, it is necessary to emphasize the importance of scientific advances, especially technologies generated by contemporary biological sciences in the area of prevention and control of diseases of public health importance.

Prevention of diseases
The knowledge generated by molecular biology has linked mutations in genes with rare disorders such as phenylketonuria and hemophilia, as well as understanding the role of genes in diseases such as cancer, rheumatoid arthritis and heart disease, between others. This knowledge has contributed to the understanding of gene function in eliminating or neutralizing agents’ pathogens. However, the true significance of genes is in the interplay with other determinants of health such as physical environment, social environment and way of life.
The public health prevention involves a range of actions aimed at reducing the risks to health of the population. Prevention is divided into three levels: primary, secondary and tertiary. Primary prevention aims to prevent the onset of disease, secondary refers detect disease at early stages, before symptoms appear, and tertiary focuses on reducing disability and restore functionality of the sick. In this context, recent technological advances in molecular biology have made remarkable contributions in the three levels of prevention. Here are some examples.

A) Primary prevention: identification of the BRCA1 gene and breast or ovarian cancer. It has been found that women with certain mutations in the BRCA1 gene have a 90 % risk of developing breast or ovarian cancer during their life. These mutations can be detected by molecular tests that determine the sequence of nitrogenous bases in DNA. The early detection of carriers of these mutations has helped identify women at high risk for developing breast or ovarian cancer and, consequently, involve them in preventive and special monitoring programs.

B) Secondary prevention: expanded newborn screening test with spectrophotometry mass analysis and DNA analysis. This test intended to diagnose in infants genetic disorders that are controlled if caught early, such as phenylketonuria, hypothyroidism, cystic fibrosis, and galactosemia and between others.

C) Tertiary Prevention: pharmacogenomic testing. Pharmacogenomic tests allow a selection or adjustment of the dose of a drug, considering the genetic makeup of patients to respond to drugs. For example, in children with acute lymphoblastic leukemia analyzing the activity of the enzyme S – thiopurine methyltransferase is indicative of the patient’s ability to metabolize specific drugs, thus increasing the therapeutic efficacy and avoiding effects toxics.

In this context, it is considered that public health efforts to incorporate recent technological advances may be directed to:
I) evaluate the impact, safety, effectiveness and quality of molecular testing in the population
II) understand how that genes, environment and lifestyle interact and how this interaction contributes to the development and progression of disease, to propose modifiable risk factors in the population, and
III) Ensure the development of programs genetic counseling in the population.

Disease control

Scientific advances have provided humanity of important health products such as drugs, vaccines, diagnostic and prognostic tests and bioinformatics platforms that incorporate mathematical models for epidemiological surveillance. All of these medical devices, along with the implementation of programs of occupational safety, environmental safety and health promotion have been the key to disease control.

Medical devices enable better performance of public health practice and help ensure global health security, detecting new threats to health. In this context, some invaluable contributions of technological advances in the recent outbreak of influenza (AH1N1) were the protocol for the identification and characterization of the virus in human samples, and the development of testing antiviral resistance.

In summary, the contributions of new technologies certainly change the paradigms in public health as well as the mission of the schools in this area. Therefore , it would be schools of public health, considering the essential functions of this AM- bite and health recommendations embodied in the Eleventh Work Programmed 2006-2015 of the World Health Organization , 22 among other governing documents , incorporating scientific advances and appropriate technology training needed to maintain the health of the population . It is urgent that new generation of graduates of schools of public health advantage of recent advances in the biological sciences, administrative and social, so that issue medical health recommendations based on a global context that is constantly changing. It is also essential to have qualified medical personnel to determine the effectiveness of interventions based on scientific evidence, which will ensure the health impact of the same.

Finally, the importance for public health professionals to disseminate their findings through publication in scientific journals is emphasized. Since the last century, scientific journals are the main means of communication between scientists, they are a reflection of how the sciences, and academic institutions. For professionals in this area of scientific journals, refereed and review committees, represent a means to present new evidence to support decision -making in the health sector. It is expected to promote the publication of this evidence that decisions contribute to health of the population achieve a balance considering scientific, administrative, political, ethical and technical aspects.

New Health technology for health
Can you help new technological applications to improve our health and wellbeing? Not an easy question to answer: there are those who believe that social networking, video games and mobile apps help to distance of a healthy lifestyle, increasingly reducing our horizon to the few inches of a computer screen or Smartphone. Others, however, believe that those few inches have the immense power to become a window on the world, a sight glass that lets you see little bits of reality and even interact with the protagonists.

What do you think about it? Surely you’re experiences with new technologies influence, and much, in your answer. From care believe that, as in everything, the secret is in the balance. Spend most of your free time online, neglecting other activities such as exercise or sit quietly at family meals is not healthy, but neither does not want to know anything about this “new” reality.

Because technology not only opens up a window to the world, it can also teach you things about yourself. For example, a few days ago we read that a team from the Hospital de Bellvitge uses a video game to treat people suffering from gambling or eating disorders. Thanks to him, a person may learn to better control your emotions (anger, anger, frustration). Another possibility for new technologies: overcoming common phobias such as fear of flying using virtual reality. -

Even the motley world of applications for Smartphone can get from you, such as smoking cessation or so doctors can evaluate diagnostic tests such as CT through mobile.
