Lopez et al. BMC Medicine 2014, 12:200 Medicine for Global Health
Remembering the forgotten non-communicablediseases Alan D Lopez1*, Thomas N Williams2,3, Adeera Levin4, Marcello Tonelli5, Jasvinder A Singh6,7,8, Peter GJ Burney9,Jürgen Rehm10,11,12,13,14, Nora D Volkow15, George Koob16 and Cleusa P Ferri17,18 The forthcoming post-Millennium Development Goals era will bring about new challenges in global health.
Low- and middle-income countries will have to contend with a dual burden of infectious and non-communicablediseases (NCDs). Some of these NCDs, such as neoplasms, COPD, cardiovascular diseases and diabetes, cause muchhealth loss worldwide and are already widely recognised as doing so. However, 55% of the global NCD burdenarises from other NCDs, which tend to be ignored in terms of premature mortality and quality of life reduction.
Here, experts in some of these ‘forgotten NCDs' review the clinical impact of these diseases along with theconsequences of their ignoring their medical importance, and discuss ways in which they can be given higherglobal health priority in order to decrease the growing burden of disease and disability.

Lopez et al. BMC Medicine 2014, 12:200 engender a similar global response, and is it warranted?The evidence would suggest it is. While neoplasms,COPD, cardiovascular diseases and diabetes cause muchhealth loss worldwide, more of the global NCD burden(55%) arises from other NCDs. These include a diverseset of causes and conditions, but among the more im-portant are musculoskeletal disorders, especially lowback and neck pain, depression, substance use disorders,cirrhosis of the liver, chronic kidney disease, asthma,various digestive diseases including peptic ulcer, anxietydisorders, congenital anomalies and haemoglobinopa-thies. Unlike the ‘big four' NCDs, many of these condi-tions cause more health loss through chronic disabilityrather than premature death; arguably, preventingchronic disability ought to be an important goal of anyhealth system (Figure The collection of comments in this Medicine for Glo- bal Health forum article is a timely reminder that im-proving population health requires a focus not only onwhat is important and well-studied, but on what is im- Figure 1 Alan Lopez is a Melbourne Laureate Professor and the portant and hitherto largely overlooked.

Pyramid: Neoplasms,COPD, cardiovascular diseases and diabetes (the ‘big four') lead to the highest proportion of disease burden among all NCDs. However, manyother NCDs lead to a comparable proportion of disease burden, yet do not receive as much attention as the ‘big four'. We have discussed sevenof these neglected NCDs (alcohol and substance abuse, liver cirrhosis, asthma, chronic kidney disease, Alzheimer's and other dementias, sickle celldisease and gout) and reviewed their disease burden. Pie chart: NCDs account for 54% of total proportion of global DALYs. Although the ‘bigfour' comprise just under half of this burden (45% of the burden of NCDs; 24.4% of the total global DALY burden) all other NCDs (i.e. theneglected NCDs) account for 55% of the burden of NCDs; 29.6% of the total global DALY burden.

Thomas N Williams (Figure Collectively, this reminds us that, unlike the acute, and largely treatable nature of communicable diseases, NCDsare complex, diverse, and manifest their impact onpopulation health in different ways. Mitigating their im-pact will require a more strategic, comprehensive andbalanced approach to NCD research, treatment and pre-vention, beyond what has been the practice for the pasthalf century or so, giving greater emphasis to those con-ditions that are major causes of health loss, and whichhitherto have been largely ignored as global health prior-ities. So, what might public health research focus on toaccelerate the recognition of neglected NCDs as a globalhealth priority? In my view, four pillars of research andknowledge translation are critical to that endeavour: i). rapidly reduce ignorance and uncertainty about the true disease burden from these conditions by cost-effectively and strategically improving cause of deathand disability data collection systems; ii). improve knowledge about the most cost-effective strategies to reduce disease burden in different pop-ulations, and about the most appropriate and afford-able approaches to financing treatment andprevention; iii). improve knowledge and understanding of established interventions for controlling the impact of the moreimportant forgotten NCDs in health care debates, andpromote targeted research on promising interventionoptions where this is lacking; and iv). raise the profile of major forgotten NCDs in national Figure 3 Tom Williams is Professor of Haemoglobinopathy and global health fora by developing policy relevant Research at Imperial College London.

Lopez et al. BMC Medicine 2014, 12:200 These global figures for morbidity and mortality should be considered in the context of data from the North, wherein recent years, many countries have adopted universalscreening for SCD and where most now provide compre-hensive care for affected individuals.

Perhapsmost importantly, we need better data, without which itwill remain difficult to persuade ministries of health,policy makers, funders and the pharmaceutical industryto devote appropriate resources to the condition. Oneessential component is better data on the birth frequen-cies and survival of children with SCD at the micro-epidemiological level, potentially through investigationsusing large-scale sample sets collected for other reasons,such as national surveys of micronutrient status, HIV ormalaria prevalence. Similarly, the implementation ofearly-life screening would be made considerably simpler Figure 5 Adeera Levin is Professor of Medicine and Head of theDivision of Nephrology, University of British Columbia, in with the development of rapid tests that would circum- Vancouver Canada.

Awareness of CKD in the global health arena will depend on continued efforts of the clinical and researchcommunities. The research agenda for nephrology remainsmultifaceted: the support for basic science discoveries is es-sential to uncover novel targets and mechanisms to fosterdrug or therapeutic developments. Scaling up existing ad-ministrative, research and clinical databases (some of whichhave large bio-banking platforms) will optimize the designof clinical trials, and allow clinicians to target the highestrisk individuals. New methods for setting research prior-ities, including the perspectives of administrators, healthpolicy makers, patients and their families, along with prac-ticing clinicians, remains critical. We need new studies thatinform evidence-based public policy and assess how best toallocate scarce resources to optimize health outcomes. Fi-nally, there is an increasing emphasis on evaluating the bestmethods for translation of research findings into practice,so that the science reliably benefits the patients.

However,as indicated above, this may constitute an underestimatefor high-income countries due to the lower case fatalityand thus higher duration of living with disability.
While the overall prevalence of liver cirrhosis mortal- ity and burden of disease seems stable, there are hugevariations by gender, age and regions [and they seemto be caused by preventable risk factors. Men have consid-erably higher rates of liver cirrhosis morality and burden ofdisease, globally more than twofold the rates of women,and highest in the men between 50 and 69 years of age.

Detecting bacillus spores by raman and surface-enhanced raman spectroscopy (sers)

Detecting Bacillus Spores by Raman and Surface-Enhanced Raman Spectroscopy (SERS) Raman spectroscopy has been employed to detect Bacillus cereusspores, an anthrax surrogate, collected from a letter as it passed Intensity (arbitrary units) through a mail sorting system. Raman spectroscopy also has the capability to identify many common substances used as hoaxes. A
