The United States\u27 Engagement in Global Tobacco Control: Proposals for Comprehensive Funding and Strategies

Tobacco use kills more people annually than HIV/AIDS, tuberculosis, and malaria combined. Unless action is taken, tobacco-related diseases will kill hundreds of millions more in coming decades, mostly in low- and middle-income countries. Beyond its effects on morbidity and mortality, tobacco use has dramatic social and economic consequences, consuming healthcare budgets, robbing families of their primary wage earners, and hindering economic development. Tobacco consumption is shifting from industrialized to developing countries, spurred by rising incomes, trade liberalization, and intensive marketing. Although Congress empowered the U.S. Food and Drug Administration to regulate tobacco domestically, the United States has failed to lead globally. The United States is among a small minority of countries that has signed, but not ratified, the World Health Organization (WHO) Framework Convention on Tobacco Control. A tiny percentage of U.S. funding for global health is dedicated to international tobacco control. U.S. trade policy has supported and enabled the industry to expand tobacco use overseas. In this Commentary, we argue for robust U.S. engagement in global tobacco control, first explaining why it is in the national interest of the United States and then suggesting a comprehensive strategy for supporting tobacco control in low- and middle-income countries

Trade, social preferences and regulatory cooperation : the new WTO-think

This paper advocates changes in the corporate governance of the World Trade Organization (WTO) to reflect the decline in tariffs and other border restraints to commerce and the emerging challenges of advancing freer trade and better regulation cooperation in a world economy dominated by global value chains. Together, these changes form an integration strategy that we refer to as the new WTO Think. This strategy remains rooted in the original rationale of the General Agreement on Trade and Tariffs (GATT) of reducing the negative externalities of unilateral action and solving important international coordination challenges, but is more inclusive of regulators and non-state actors and more flexible and positive in its means. In particular, we advocate that the WTO should embrace the confluence of shared social preferences and trade, where it exists, as a motivation for advancing international regulatory cooperation. The WTO should also multilateralize the important regulatory cooperation occurring in smaller clubs of like-minded countries and better facilitate the use of plurilateral agreements where consensus across all WTO members is not yet possible

Geographic and species association of hepatitis B virus genotypes in non-human primates

AbstractInfection with hepatitis B virus (HBV) has been detected in human populations thoughout the world, as well as in a number of ape species (Pan troglodytes, Gorilla gorilla, gibbons [Nomascus and Hylobates species] and Pongo pygmaeus). To investigate the distribution of naturally occurring HBV infection in these species and other African Old World monkey species (Cercopithecidae), we screened 137 plasma samples from mainly wild caught animals by polymerase chain reaction (PCR) using several of highly conserved primers from the HB surface (HBs) gene, and for HBs antigen (HBsAg) by ELISA. None of the 93 Cercopithecidae screened (6 species) showed PCR or serology evidence for HBV infection; in contrast 2 from 8 chimpanzees and 5 from 22 gibbons were PCR-positive with each set of primers.Complete genome sequences from each of the positive apes were obtained and compared with all previously published complete and surface gene sequences. This extended phylogenetic analysis indicated that HBV variants from orangutans were interspersed by with HBV variants from southerly distributed gibbon species (H. agilis and H. moloch) occupying overlapping or adjacent habitat ranges with orangutans; in contrast, HBV variants from gibbon species in mainland Asia were phylogenetically distinct. A geographical rather than (sub)species association of HBV would account for the distribution of HBV variants in different subspecies of chimpanzees in Africa, and explain the inlier position of the previously described lowland gorilla sequence in the chimpanzee clade. These new findings have a number of implication for understanding the origins and epidemiology of HBV infection in non-human primates

Global susceptibility and response to noncommunicable diseases.

Globalization and human interdependence have created immeasurable value for humanity. These forces, however, also provide channels for health risks to spread throughout the world. Global functions for health, such as international partnerships or research and development, are a rational response to global health risks like pandemics or globalized supply chains. Self-interest compels governments – or donors – to provide global functions even though their benefits are widely shared the world over

Healthcare Access and Quality Index based on mortality from causes amenable to personal health care in 195 countries and territories, 1990-2015: a novel analysis from the Global Burden of Disease Study 2015

Background National levels of personal health-care access and quality can be approximated by measuring mortality rates from causes that should not be fatal in the presence of effective medical care (ie, amenable mortality). Previous analyses of mortality amenable to health care only focused on high-income countries and faced several methodological challenges. In the present analysis, we use the highly standardised cause of death and risk factor estimates generated through the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) to improve and expand the quantification of personal health-care access and quality for 195 countries and territories from 1990 to 2015. Methods We mapped the most widely used list of causes amenable to personal health care developed by Nolte and McKee to 32 GBD causes. We accounted for variations in cause of death certification and misclassifications through the extensive data standardisation processes and redistribution algorithms developed for GBD. To isolate the effects of personal health-care access and quality, we risk-standardised cause-specific mortality rates for each geography-year by removing the joint effects of local environmental and behavioural risks, and adding back the global levels of risk exposure as estimated for GBD 2015. We employed principal component analysis to create a single, interpretable summary measure–the Healthcare Quality and Access (HAQ) Index–on a scale of 0 to 100. The HAQ Index showed strong convergence validity as compared with other health-system indicators, including health expenditure per capita (r=0·88), an index of 11 universal health coverage interventions (r=0·83), and human resources for health per 1000 (r=0·77). We used free disposal hull analysis with bootstrapping to produce a frontier based on the relationship between the HAQ Index and the Socio-demographic Index (SDI), a measure of overall development consisting of income per capita, average years of education, and total fertility rates. This frontier allowed us to better quantify the maximum levels of personal health-care access and quality achieved across the development spectrum, and pinpoint geographies where gaps between observed and potential levels have narrowed or widened over time. Findings Between 1990 and 2015, nearly all countries and territories saw their HAQ Index values improve; nonetheless, the difference between the highest and lowest observed HAQ Index was larger in 2015 than in 1990, ranging from 28·6 to 94·6. Of 195 geographies, 167 had statistically significant increases in HAQ Index levels since 1990, with South Korea, Turkey, Peru, China, and the Maldives recording among the largest gains by 2015. Performance on the HAQ Index and individual causes showed distinct patterns by region and level of development, yet substantial heterogeneities emerged for several causes, including cancers in highest-SDI countries; chronic kidney disease, diabetes, diarrhoeal diseases, and lower respiratory infections among middle-SDI countries; and measles and tetanus among lowest-SDI countries. While the global HAQ Index average rose from 40·7 (95% uncertainty interval, 39·0–42·8) in 1990 to 53·7 (52·2–55·4) in 2015, far less progress occurred in narrowing the gap between observed HAQ Index values and maximum levels achieved; at the global level, the difference between the observed and frontier HAQ Index only decreased from 21·2 in 1990 to 20·1 in 2015. If every country and territory had achieved the highest observed HAQ Index by their corresponding level of SDI, the global average would have been 73·8 in 2015. Several countries, particularly in eastern and western sub-Saharan Africa, reached HAQ Index values similar to or beyond their development levels, whereas others, namely in southern sub-Saharan Africa, the Middle East, and south Asia, lagged behind what geographies of similar development attained between 1990 and 2015. Interpretation This novel extension of the GBD Study shows the untapped potential for personal health-care access and quality improvement across the development spectrum. Amid substantive advances in personal health care at the national level, heterogeneous patterns for individual causes in given countries or territories suggest that few places have consistently achieved optimal health-care access and quality across health-system functions and therapeutic areas. This is especially evident in middle-SDI countries, many of which have recently undergone or are currently experiencing epidemiological transitions. The HAQ Index, if paired with other measures of health-system characteristics such as intervention coverage, could provide a robust avenue for tracking progress on universal health coverage and identifying local priorities for strengthening personal health-care quality and access throughout the world

The Toll-Like Receptor Signaling Molecule Myd88 Contributes to Pancreatic Beta-Cell Homeostasis in Response to Injury

Commensal flora and pathogenic microbes influence the incidence of diabetes in animal models yet little is known about the mechanistic basis of these interactions. We hypothesized that Myd88, an adaptor molecule in the Toll-like-receptor (TLR) pathway, regulates pancreatic β-cell function and homeostasis. We first examined β-cells histologically and found that Myd88−/− mice have smaller islets in comparison to C57Bl/6 controls. Myd88−/− mice were nonetheless normoglycemic both at rest and after an intra-peritoneal glucose tolerance test (IPGTT). In contrast, after low-dose streptozotocin (STZ) challenge, Myd88−/−mice had an abnormal IPGTT relative to WT controls. Furthermore, Myd88−/− mice suffer enhanced β-cell apoptosis and have enhanced hepatic damage with delayed recovery upon low-dose STZ treatment. Finally, we treated WT mice with broad-spectrum oral antibiotics to deplete their commensal flora. In WT mice, low dose oral lipopolysaccharide, but not lipotichoic acid or antibiotics alone, strongly promoted enhanced glycemic control. These data suggest that Myd88 signaling and certain TLR ligands mediate a homeostatic effect on β-cells primarily in the setting of injury

Oral Rehydration Salts, Cholera, and the Unfinished Urban Health Agenda

Cholera has played an outsized role in the history of how cities have transformed from the victims of disease into great disease conquerors. Yet the current burden of cholera and diarrheal diseases in the fast-urbanizing areas of low-income nations shows the many ways in which the urban health agenda remains unfinished and must continue to evolve

Bridging the Gap: Improving Clinical Development and the Regulatory Pathways for Health Products for Neglected Diseases

There has been tremendous progress over the last decade in the development of health products for neglected diseases. These include drugs, vaccines, and diagnostics for malaria and tuberculosis, which kill millions of people annually, plus other diseases like changes and dengue fever, which may less familiar, but nonetheless exact a large and often lethal toll in the world’s poorest communities. Led by product development public- private partnerships (PDPs) and fueled by the support of the Bill & Melinda Gates Foundation, the National Institutes of Health, and other donors, there are now dozens of candidate products in the pipeline.
