  • Why deep networks generalize despite going against statistical intuition

    Why deep networks generalize despite going against statistical intuition

    Introductory statistics courses teach us that, when fitting a model to some data, we should have more data than free parameters to avoid the danger of overfitting—fitting noisy data too closely, and thereby failing to fit new data. It is surprising, then, that in modern deep learning the practice is to have orders of magnitude more parameters than data. Despite this, deep networks show good predictive performance, and in fact do better the more parameters they have. Why would that be?

    Deep-learning system detects human presence by harvesting RF signals

    Researchers at Syracuse University in New York have recently developed a system that can detect the presence of humans in a given environment by analyzing ambient radio frequency (RF) signals. This new system, presented in a paper pre-published on arXiv, employs a convolutional neural network (CNN) trained on a vast amount of RF data.

  • WHO steps up action to improve access to safe blood

    WHO steps up action to improve access to safe blood

    The World Health Organization’s new action plan to speed up universal access to safe blood and blood products pulls together existing recommendations and recommends new improved ways of working. It’s the start of a four-year collaborative effort to improve blood transfusion and blood-based therapies in all countries.

    Safe blood saves lives in all sorts of circumstances, not least in emergency and epidemic settings. Blood transfusion and blood products are critical for birth delivery for both the mother and baby; the survival and quality of life of patients suffering from life-threatening conditions such as haemophilia, thalassemia, immune deficiency and cancer; treating severe injuries and carrying out medical and surgical procedures.  

    But progress in blood safety and availability has been slow in many parts of the world, placing patients’ safety at risk and putting undue pressure on health workers. Progress is also mostly restricted to developed countries. Out of the approximate 118 million blood donations collected globally, 42% are collected in high-income countries, home to 16 % of the world’s population. And one out of four low-income countries do not test all donated blood, while 54% of countries do not have surveillance systems to securitise the supply chain from blood donor to patient. 

    Challenges include: slow implementation of national blood policies and weak blood regulatory systems; insufficient number of voluntary blood donors (who are considered the safest donors); poor quality management of screening tests, blood grouping and compatibility testing; inappropriate clinical use of blood; insufficient national funding for blood safety.

    To address these, WHO has set out six key objectives for all countries and in particular those with weak blood systems:

    • appropriately structured, well-coordinated and sustainably resourced national blood systems;
    • regulatory capacity to ensure the quality and safety of blood;
    • functioning and efficiently managed blood services;
    • effective implementation of patient blood management to optimize transfusion practices;
    • effective surveillance, haemovigilance and pharmacovigilance, supported by comprehensive and accurate data collection systems;
    • partnerships, collaboration and information exchange to achieve key priorities and jointly address challenges and emerging threats at global, regional and national levels.

    The Organization looks forward to working with partners worldwide to implement the plan, improve blood supply particularly in the low and middle-income countries where this is so urgently needed, and save lives. The plan will run from 2020-2024.

  • The economic cost of female genital mutilation

    The economic cost of female genital mutilation

    An interactive data tool launched by WHO reveals for the first time the current and future financial cost of health care for women living with conditions caused by female genital mutilation (FGM).

    The total costs amount to USD 1.4 billion annually.

    fgm-cost-thumbnail

    The FGM Cost Calculator is being launched on this year’s International Day of Zero Tolerance for FGM. This new tool shows that if FGM were abandoned now the associated savings
    in health costs would be more than 60% by 2050. This data, available for 27 of the 30 countries where FGM is practiced, will strengthen the economic argument of community activists, policy makers, programme planners and donors working to end this
    human rights violation.

    Q&As on the FGM Cost Calculator
    Access the FGM Cost Calculator

    A human rights violation with economic costs

    FGM includes procedures that intentionally alter or cause injury to the female genital organs for non-medical reasons. More than 200 million girls and women alive today have been cut in 30 countries in Africa, the Middle East and Asia where FGM is concentrated.
    [1] An extreme form of gender discrimination, it is recognized internationally as a violation of the human rights of girls and women: including the right to health, security and physical integrity and the right to be free from torture and cruel, inhuman
    or degrading treatment.

    FGM has no health benefits and causes only harm. Women and girls who are subjected to FGM are at risk of both short- and long-term negative health consequences – including for their physical, sexual, mental, and social well-being.

    The direct financial cost of treating the negative health complications caused by FGM can span generations, starting as early as childbirth. This puts a significant economic burden on health systems and national budgets, especially in countries with rates
    of FGM greater than 10%.

    Until now, there have been limited data on the financial costs associated with FGM, making it hard to demonstrate the cost-effectiveness of programmes and policies that can prevent FGM by 2030 – a global priority in the Sustainable Development Agenda.
    The new WHO Cost Calculator now provides an economic argument which can be used by those advocating for an end to FGM.

    Calculating health care costs of FGM

    Users of the new FGM Cost Calculator can choose a country and identify current costs of treating health conditions caused by FGM. Since the tool is interactive, it produces bespoke graphs showing the potential amount of money saved if FGM is prevented
    by a selected percentage.

    If no action is taken to prevent FGM, it is estimated that related health costs will soar by 50% by 2050, as populations grow and as more girls undergo the procedure.

    How it works

    The FGM Cost Calculator combines data on health risk associated with FGM, health costs and national FGM prevalence to analyze the economic impact on national health services of treating the consequences of these harmful practices.

    Health risk data were taken from a WHO database created for this analysis, pooling all available information from systematic reviews of health consequences of FGM. The following categories were used, each with a biological link to FGM: gynaecological,
    obstetric, urological, mental and sexual, as well as the immediate health complications that can result following the cutting.

    To be included in the calculator, a health condition needed to show evidence of increased risk when comparing women with and without FGM. It also needed to have a treatment which could be implemented and costed in the health sector.

    Health costs were calculated from the WHO One Health Tool and other data. The financial burden of treating selected health conditions was calculated at a national level.

    A strong case for investment in preventing FGM

    Rates of FGM have declined over the past 30 years, but not fast enough to keep up with population growth. If trends continue, the number of girls and women undergoing FGM will rise significantly in the next 15 years, in turn raising national health care
    costs of caring for them.

    Additional resources are urgently needed to scale up interventions that can prevent FGM in the future and reduce health complications.

    By providing quantifiable numbers on the cost of treating health conditions directly linked to FGM, for the first time, the FGM Cost Calculator can be a crucial tool in building an investment case for a future where no girl or woman is cut.

  • E-cigarettes are harmful to health

    E-cigarettes are harmful to health

    Globally, there are 1.1 billion adult smokers, 60% of them want or intend to quit. Much has been written and said about the potential of electronic nicotine delivery systems (ENDS) such as e-cigarettes to help tobacco users quit. While the evidence is still inconclusive, e-cigarettes are often used along with one or more tobacco products. As this is the practice with many ENDS users, the health effects of two or more products are combined. Governments who want to weigh the potential benefits and risks of e-cigarettes for their population should consider the following:

    1. Regarding the potential health effects for which the evidence is mounting, there is insufficient data to understand the full breadth of their impact on health as devices have not been on the market long enough. Especially the long-term effects of using e-cigarettes or being exposed to them are yet unknown.
    2. Nevertheless, the evidence is clear that the aerosols of the majority of ENDS contain toxic chemicals, including nicotine and substances that can cause cancer.ENDS on their own are associated with increased risk of cardiovascular diseases and lung disorders and adverse effects on the development of the fetus during pregnancy. ENDS are undoubtedly harmful, should be strictly regulated, and, most importantly, must be kept away from children. Nicotine is highly addictive and found in most e-cigarettes. Both tobacco products and e-cigarettes pose risks to health and the safest approach is not to consume either.
    3. It is of particular public health concern that increasingly children and adolescents take up the use of e-cigarettes in some countries. Most ENDS can be manipulated by the user. Some manufacturers also hold patents to remotely manipulate nicotine dosages and toxicant delivery. Furthermore, there is a growing body of evidence in some countries that never-smoker adolescents who use ENDS at least double their chance of starting to smoke cigarettes later in life. Exposing children and adolescents to nicotine can have long-lasting, damaging effects on brain development and lead to nicotine addiction.

    WHO continues to monitor the evidence and technological developments and will adapt this statement accordingly.

  • WHO Action framework to advance universal access to safe, effective and quality assured blood products 2020 -2023

    WHO Action framework to advance universal access to safe, effective and quality assured blood products 2020 -2023

    In response to calls for action, WHO has provided guidelines, physical standards, training and technical support to improve blood product quality, safety and availability in WHO regions and in countries. Despite these actions, progress in blood availability and safety under effective regulation has been slow in many parts of the world.

    For that reason, the WHO Action framework for blood products 2020-2023, proposes a renewed effort to scale up programme implementation to improve global adequacy of blood donation, and universal access to quality and safe blood and blood components for transfusion, and plasma derived medicinal products.

    The Action Framework provides strategic direction to WHO’s work for the years 2020-2023. It identifies six strategic objectives: appropriately structured, well-coordinated and sustainably resourced national blood systems; regulatory capacity to ensure the quality and safety of blood; functioning and efficiently managed blood services; effective implementation of patient blood management to optimize transfusion practices, effective surveillance, haemovigilance and pharmacovigilance, supported by comprehensive and accurate data collection systems; and partnerships, collaboration and information exchange to achieve key priorities and jointly address challenges and emerging threats at global, regional and national levels.

    The Action Framework will improve coordination and collaboration at all levels of WHO. The document will promote and strengthen new and existing partnerships, as areas for collaborative action are clearly identified. Moreover, it demonstrates the need for support to WHO (including sustainable funding) to coordinate the implementation of this ambitious plan. As a result, the Action Framework for blood products will allow WHO to more effectively carry out its mandate on blood, and to increase the impact of WHO activities to strengthen blood systems and blood regulation in countries and regions and eventually to ensure universal access to blood products worldwide.
