    Digitizing Healthcare: How Technology Is Improving Medical Care 

                                                                                                                        by Tricia Hussung


    A wide variety of digital innovations are revolutionizing healthcare — and technology in medicine is here to stay. How are these changes impacting the delivery of care, and what skills are needed to succeed in this bold new world? It’s no secret that, as a society, technology has become a part of our everyday lives. In fact, almost 60 percent of American adults own a smartphone, and 42 percent of that same population (American adults) owns a tablet computer. Though technology has been permeating almost every aspect of our lives, until recent years the medical field has been largely unaffected by the rapid pace of technological innovation that is characteristic of the Digital Age. However, this is changing.


    This ubiquity of technology is beginning to extend into the medical field. Advances in medical technology are changing medicine by giving physicians more information — as well as better, more specific data. 


    New Medical Technology: Innovations

    So just what are these new advances in technology? The following are just a few of the many innovations that have occurred in medical technology over the past year alone. Some of these leading technologies are still being developed, while others are slowly being introduced into mainstream medical practice.


    • The modern hospital experience: Several medical technology companies are looking to update hospital stays to keep pace with the needs of modern patients. To more easily integrate changing technology, these new rooms would feature interchangeable parts that are easily adapted to the specific situation of a patient. The seamless design would have a minimal impact on facility operations while increasing patient comfort and connectivity.
    • Surgery simulation: The Roswell Park Cancer Institute has partnered with the University of Buffalo’s School of Engineering and Applied Sciences to create the Robotic Surgery Simulator (RoSS). This innovation allows real-world views of surgeries while eliminating the need for a live environment to train aspiring surgeons. It gives these medical professionals the space to experiment in a simulated environment, rather than risking making mistakes on real patients.
    • Cloud-based data and software: Applications like referralMD help healthcare providers create referrals digitally and reach millions of patients and providers who are in search of treatment options. The current, paper method of referrals causes almost 50 percent of patient referrals to never actually result in doctor’s visits. This present gap in care “causes patients to lose treatment (and) the healthcare facility to lose money.” Software innovations like these are part of the relatively new field of health informatics, which aims to collect, store, analyze and present health data in a digital format. 

    With widespread innovations like these affecting patient care practices, it is not surprising that the way medical records and information are stored and shared is changing as well. These technological advancements are costeffective and improve the ability of medical professionals to diagnose and treat health issues of all kinds. Two of the main changes that are revolutionizing the future of healthcare are electronic medical records and health information exchange. Future won´t be the same for medical field. Are you ready for what is coming?

    Thematic Discussion on Nuclear Weapons

        The United States remains committed to the goal of nuclear disarmament, and to seeking to create conditions toward that end. And history makes clear that important progress can be made when security conditions allow. The easing of Cold War rivalries allowed the United States and Russia to make significant steps toward the shared dream of eventual nuclear disarmament after decades in which such movement was impossible. Disarmament success is predicated on patience, attention to detail, effective verification, and patient attention to the challenges of effecting the changes in the security environment that are necessary for progress. This last element is critical, considering the crucial role that nuclear deterrence plays in preserving and protecting international peace and security, and the potentially catastrophic consequences were deterrence’s restraining effect to be removed while it still remains necessary.

        The “Treaty on the Prohibition of Nuclear Weapons” violates all these tenets. Its obligations are longstanding worded, imprecise, vaguely worded and sometimes internally contradictory, while offering only an empty shell for verification. Worse, it is fundamentally at odds with today’s security challenges. It is not simply an unproductive instrument; it is likely to be a counterproductive one, with the potential to cause lasting harm to the nonproliferation regime and to the cause of disarmament alike.

        The ban treaty is based on the premise that addressing crucial international security issues is not necessary for disarmament. Ban treaty proponents would have us believe that we can do away with nuclear deterrence despite - to cite just one example - the danger posed by North Korea’s relentless pursuit of nuclear weapons and associated delivery systems, which stand in flagrant violation of international law.

         Furthermore, the Treaty does not contain a credible verification mechanism, demurring on the issue almost entirely. It does run counter to decades of progress in nonproliferation verification by endorsing the International Atomic Energy Agency (IAEA) Comprehensive Safeguards Agreement as its standard for safeguarding nuclear material.

        Finally, the ban treaty has the potential to do real damage to the Non Proliferation Treaty (NPT) in other ways. It exacerbates political tensions on disarmament, dividing states into overly-simplified camps of “nuclear weapons supporters” and “nuclear weapons banners,” rather than recognizing shared interests – especially on the challenges involved in creating the conditions that would make possible further disarmament progress. Reinforcing this false dichotomy and worsening the world’s polarization on disarmament will make further progress within the institutions that have been vehicles for success, such as the NPT review process, significantly more difficult.

        Inspired by the NPT Preamble’s acknowledgement of the need to ease international tension and strengthen trust between States in order to facilitate disarmament, the United States stands ready to work with others on effective measures to create improved conditions for nuclear disarmament. This work is focused on overcoming technical challenges to make substantive progress when the security conditions improve. We also continue our longstanding work to support and strengthen the global nonproliferation regime against the many challenges it faces today, for who could deny that there can be no way to envision today’s nuclear weapons possessors ever putting down such tools without rock-solid assurances that no one else will take them up?

        There are no shortcuts to nuclear disarmament. Unrealistic attempts to skip to the finish line have the potential to undermine the institutions and standards we have worked so hard to build. Our collective experience demonstrates that inclusiveness and the search for consensus can lead to progress, while polarization is a recipe for failure. We urge all states to work with us in searching for common solutions to collective problems, pursuing a more secure world.

Num determinado momento (situação I), o fio A passa a transportar uma corrente elétrica IA e o fio B permanece sem transportar corrente alguma, ou seja, IB = 0.
