The global burden of non-communicable diseases (NCDs) is growing, and there is an urgent need to estimate the costs and benefits of an investment strategy to prevent and control NCDs. Results from an investment-case analysis can provide important new evidence to inform decision making by governments and donors. We propose a methodology for calculating the economic benefits of investing in NCDs during the Sustainable Development Goals (SDGs) era, and we applied this methodology to cardiovascular disease prevention in 20 countries with the highest NCD burden. For a limited set of prevention interventions, we estimated that US$120 billion must be invested in these countries between 2015 and 2030. This investment represents an additional $1·50 per capita per year and would avert 15 million deaths, 8 million incidents of ischaemic heart disease, and 13 million incidents of stroke in the 20 countries. Benefit–cost ratios varied between interventions and country-income levels, with an average ratio of 5·6 for economic returns but a ratio of 10·9 if social returns are included. Investing in cardiovascular disease prevention is integral to achieving SDG target 3.4 (reducing premature mortality from NCDs by a third) and to progress towards SDG target 3.8 (the realisation of universal health coverage). Many countries have implemented cost-effective interventions at low levels, so the potential to achieve these targets and strengthen national income by scaling up these interventions is enormous.

Adolescent growth and social development shape the early development of offspring from preconception through to the post-partum period through distinct processes in males and females. At a time of great change in the forces shaping adolescence, including the timing of parenthood, investments in today’s adolescents, the largest cohort in human history, will yield great dividends for future generations. Investing in adolescents as the parents of the next generation is important for the wellbeing of current and future generations. The afterlife of adolescence Adolescence is increasingly recognized as a developmental period that has a potential for influencing life-course trajectories that is second only to early life, but that could also shape the growth and development of the following generation. George Patton and colleagues review the evidence around how an individual's health, growth and nutrition during adolescence may affect the early growth of their offspring, and consider potential mechanisms for transmission. The current generation of adolescents—now considered to be all those aged between 10 and 24—will be the largest in human history to become parents. The greatest dividends from investments in today's adolescents may be seen in the health and human capabilities of the next generation.

Investment in the capabilities of the world's 1·2 billion adolescents is vital to the UN's Sustainable Development Agenda. We examined investments in countries of low income, lower-middle income, and upper-middle income covering the majority of these adolescents globally to derive estimates of investment returns given existing knowledge. The costs and effects of the interventions were estimated by adapting existing models and by extending methods to create new modelling tools. Benefits were valued in terms of increased gross domestic product and averted social costs. The initial analysis showed high returns for the modelled interventions, with substantial variation between countries and with returns generally higher in low-income countries than in countries of lower-middle and upper-middle income. For interventions targeting physical, mental, and sexual health (including a human papilloma virus programme), an investment of US$4·6 per capita each year from 2015 to 2030 had an unweighted mean benefit to cost ratio (BCR) of more than 10·0, whereas, for interventions targeting road traffic injuries, a BCR of 5·9 (95% CI 5·8–6·0) was achieved on investment of $0·6 per capita each year. Interventions to reduce child marriage ($3·8 per capita each year) had a mean BCR of 5·7 (95% CI 5·3–6·1), with the effect high in low-income countries. Investment to increase the extent and quality of secondary schooling is vital but will be more expensive than other interventions—investment of $22·6 per capita each year from 2015 to 2030 generated a mean BCR of 11·8 (95% CI 11·6–12·0). Investments in health and education will not only transform the lives of adolescents in resource-poor settings, but will also generate high economic and social returns. These returns were robust to substantial variation in assumptions. Although the knowledge base on the impacts of interventions is limited in many areas, and a major research effort is needed to build a more complete investment framework, these analyses suggest that comprehensive investments in adolescent health and wellbeing should be given high priority in national and international policy.

A new Global Investment Framework for Women's and Children's Health demonstrates how investment in women's and children's health will secure high health, social, and economic returns. We costed health systems strengthening and six investment packages for: maternal and newborn health, child health, immunisation, family planning, HIV/AIDS, and malaria. Nutrition is a cross-cutting theme. We then used simulation modelling to estimate the health and socioeconomic returns of these investments. Increasing health expenditure by just $5 per person per year up to 2035 in 74 high-burden countries could yield up to nine times that value in economic and social benefits. These returns include greater gross domestic product (GDP) growth through improved productivity, and prevention of the needless deaths of 147 million children, 32 million stillbirths, and 5 million women by 2035. These gains could be achieved by an additional investment of $30 billion per year, equivalent to a 2% increase above current spending.

We investigated the short- and long-term effects of ceftriaxone on glutamate transporter subtype 1 (GLT-1) transporter activity and extracellular glutamate in the rat nucleus accumbens. Repeated ceftriaxone administration (50, 100 or 200 mg/kg, i.p.) produced a dose-dependent reduction in glutamate levels that persisted for 20 days following discontinuation of drug exposure. The ceftriaxone effect was prevented by the GLT-1 transporter inhibitor dihydrokainate (1 μM, intra-accumbal). These results suggest that β-lactam antibiotics produce an enduring reduction in glutamatergic transmission in the brain reward center.

Acutely administered N-methyl-D-asparate (NMDA) antagonists are used to model schizophrenia, as measured by impairments in sensorimotor gating reflected in decreases in prepulse inhibition of the startle response (PPI). Aspects of acute NMDA receptor antagonism limit the applications of these models. The aim of this paper is to determine the long-term effects of developmental phencyclidine (PCP) treatment on sensorimotor gating in both male and female rats. Male and female Sprague Dawley rats were injected with PCP (10 mg/kg s.c.) on postnatal days (PN) 7, 9, and 11 and were tested for PPI on PN 32-34. The groups were then divided and some of the animals received a single dose of PCP (10 mg/kg s.c.) on PN 45. The animals were tested again for PPI at approximately 1, 4, and 6 weeks after the treatment. There were no significant effects of neonatal-only treatment. One week after the PN 45 treatment, animals that were treated as neonates and as adolescents (PCP/PCP) were significantly impaired in PPI in both sexes. Male and female PCP/PCP rats also had significant increases in acoustic startle response 4 weeks posttreatment, which subsequently declined. PPI impairments in both sexes recovered over time and the adolescent-only treated females showed significant increases (improvement) in PPI approximately 6 weeks posttreatment. These data suggest that treatment with an NMDA receptor antagonist during adolescence or early adulthood can produce a relatively long-term impairment of PPI (approximately 1 week) and that this effect is more pronounced in male animals.

Nanotechnology is the latest in a series of general purpose technologies (GPT), earlier examples of which, have transformed household life, industry structure and firm performance. This paper traces the development to date of one of the first uses of nanotechnology to synthesise a new drug. Using an innovation systems framework, the paper compares the commercialisation process of this drug with that typically employed by a biotechnology company, to explore differences arising from the novel nature of the underlying technology. The study finds that the commercialisation process, followed by the company developing the drug, conforms substantially to the empirical literature on biotechnology commercialisation. However it departs in two important ways. One is the absence of venture capital involvement and the second is the failure to date to form an alliance with a major pharmaceutical company. The evidence suggests that while both reflect factors that relate to conditions in the Australian market, the novel nature of the technology may be an issue in the latter.

[...]disasters can lead to new opportunities to advance health reform agendas and strengthen the health system, something that Mexico took advantage of after a devastating earthquake in 1985.13 Our experience in Pakistan after the 2005 earthquake successfully built on new opportunities to strengthen district health systems and improve health outcomes for mothers and children.14 Increased political will, additional resources, effective partnership between the health system and international partners, and the commitment and participation of local communities were key enabling factors.15 Gideon Mendel/Corbis There is little doubt that in some cases disaster response programming has been inefficient and ineffective, with opportunities and resources squandered and inadequate accountability structures.16 In the public health sector more rigorous documentation and analysis of emergency response measures and results would be enlightening.

We cannot afford to ignore the needs of this growing sector of the population, argue David Ross and colleagues
