The Cost-Effectiveness of Intermittent Preventive Treatment for Malaria in Infants in Sub-Saharan Africa

BACKGROUND: Intermittent preventive treatment in infants (IPTi) has been shown to decrease clinical malaria by approximately 30% in the first year of life and is a promising malaria control strategy for Sub-Saharan Africa which can be delivered alongside the Expanded Programme on Immunisation (EPI). To date, there have been limited data on the cost-effectiveness of this strategy using sulfadoxine pyrimethamine (SP) and no published data on cost-effectiveness using other antimalarials. METHODS: We analysed data from 5 countries in sub-Saharan Africa using a total of 5 different IPTi drug regimens; SP, mefloquine (MQ), 3 days of chlorproguanil-dapsone (CD), SP plus 3 days of artesunate (SP-AS3) and 3 days of amodiaquine-artesunate (AQ3-AS3).The cost per malaria episode averted and cost per Disability-Adjusted Life-Year (DALY) averted were modeled using both trial specific protective efficacy (PE) for all IPTi drugs and a pooled PE for IPTi with SP, malaria incidence, an estimated malaria case fatality rate of 1.57%, IPTi delivery costs and country specific provider and household malaria treatment costs. FINDINGS: In sites where IPTi had a significant effect on reducing malaria, the cost per episode averted for IPTi-SP was very low, USD 1.36-4.03 based on trial specific data and USD 0.68-2.27 based on the pooled analysis. For IPTi using alternative antimalarials, the lowest cost per case averted was for AQ3-AS3 in western Kenya (USD 4.62) and the highest was for MQ in Korowge, Tanzania (USD 18.56). Where efficacious, based only on intervention costs, IPTi was shown to be cost effective in all the sites and highly cost-effective in all but one of the sites, ranging from USD 2.90 (Ifakara, Tanzania with SP) to USD 39.63 (Korogwe, Tanzania with MQ) per DALY averted. In addition, IPTi reduced health system costs and showed significant savings to households from malaria cases averted. A threshold analysis showed that there is room for the IPTi-efficacy to fall and still remain highly cost effective in all sites where IPTi had a statistically significant effect on clinical malaria. CONCLUSIONS: IPTi delivered alongside the EPI is a highly cost effective intervention against clinical malaria with a range of drugs in a range of malaria transmission settings. Where IPTi did not have a statistically significant impact on malaria, generally in low transmission sites, it was not cost effective

Assessment of the economic performance of the seabream and seabass aquaculture industry in the European Union

Production of gilthead seabream (Sparus aurata) and European seabass (Dicentrarchus labrax) is the second most important aquaculture industry in the European Union in value terms. During the last 10 years, the industry has experienced a process of industry concentration with the aim to overcome efficiency and profitability issues. However, the economic performance of the companies is still in general rather poor. The present work analyzes the economic performance of EU seabream and seabass companies in the period 2008?2016. The work is the first study to analyze companies? profitability in the EU as a whole, by country and company size, using economic and financial data extracted from companies? annual accounts. Based on the results, the study discusses the improvement of production and business profitability in recent years and the different factors that may have caused it, as well as the challenges and threats that seabream and seabass companies will have to face in order to achieve economic sustainability.This research was undertaken under the MedAID project, which has received funding from the European Union's Horizon 2020 Research and Innovation Programme under grant agreement no 727315 (http://www.medaid-h2020.eu/)

"So I Feel Like I’m Getting It and Then Sometimes I Think OK, No I’m Not": couple and family therapists learning an evidence-based practice

This research concerns itself with the experiences of couple and family therapists (CFT) learning about and using an evidence-based practice. The engagement with evidence-based practice is growing across many aspects of the mental health and health care systems. The evidence-based practice model is now being applied in a broad range of health and human service systems, including mental and behavioral health care, social work, education, and criminal justice (Hunsley, 2007). The dialogue about the role of evidence-based approaches in the practice of couple and family therapy and research literature about same is also evolving (Sexton et al., 2011; Sprenkle 2012). Interestingly, while the research delves into what are the best approaches with different populations and presenting issues, little research has explored the experience of CFTs themselves, particularly while learning and adopting an evidence-based practice. Using a phenomenological approach called interpretive phenomenological analysis (Smith, Flowers, & Larking, 2009), this research explored the experiences of CFTs learning and using an evidence-based practice. The paper reports key issues, challenges, and areas for CFTs, educators, and supervisors. As researchers, educators, administrators, policy makers, and CFTs struggle with what works best with which populations and when, how best to allocate resources, how best to educate and support CFTs, and the complexity of doing research in real-life settings, this research has the potential to contribute to those varied dialogues

Interplays between copper and Mycobacterium tuberculosis GroEL1

The recalcitrance of pathogenic Mycobacterium tuberculosis, the agent of tuberculosis, to eradication is due to various factors allowing bacteria to escape from stress situations. The mycobacterial chaperone GroEL1, overproduced after macrophage entry and under oxidative stress, could be one of these key players. We previously reported that GroEL1 is necessary for the biosynthesis of phthiocerol dimycocerosate, a virulence-associated lipid and for reducing antibiotic susceptibility. In the present study, we showed that GroEL1, bearing a unique C-terminal histidine-rich region, is required for copper tolerance during Mycobacterium bovis BCG biofilm growth. Mass spectrometry analysis demonstrated that GroEL1 displays high affinity for copper ions, especially at its C-terminal histidine-rich region. Furthermore, the binding of copper protects GroEL1 from destabilization and increases GroEL1 ATPase activity. Altogether, these findings suggest that GroEL1 could counteract copper toxicity, notably in the macrophage phagosome, and further emphasizes that M. tuberculosis GroEL1 could be an interesting antitubercular target

XVI International Congress of Control Electronics and Telecommunications: "Techno-scientific considerations for a post-pandemic world intensive in knowledge, innovation and sustainable local development"

Este título, sugestivo por los impactos durante la situación de la Covid 19 en el mundo, y que en Colombia lastimosamente han sido muy críticos, permiten asumir la obligada superación de tensiones sociales, políticas, y económicas; pero sobre todo científicas y tecnológicas. Inicialmente, esto supone la existencia de una capacidad de la sociedad colombiana por recuperar su estado inicial después de que haya cesado la perturbación a la que fue sometida por la catastrófica pandemia, y superar ese anterior estado de cosas ya que se encontraban -y aún se encuentran- muchos problemas locales mal resueltos, medianamente resueltos, y muchos sin resolver: es decir, habrá que rediseñar y fortalecer una probada resiliencia social existente - producto del prolongado conflicto social colombiano superado parcialmente por un proceso de paz exitoso - desde la tecnociencia local; como lo indicaba Markus Brunnermeier - economista alemán y catedrático de economía de la Universidad de Princeton- en su libro The Resilient Society…La cuestión no es preveerlo todo sino poder reaccionar…aprender a recuperarse rápido.This title, suggestive of the impacts during the Covid 19 situation in the world, and which have unfortunately been very critical in Colombia, allows us to assume the obligatory overcoming of social, political, and economic tensions; but above all scientific and technological. Initially, this supposes the existence of a capacity of Colombian society to recover its initial state after the disturbance to which it was subjected by the catastrophic pandemic has ceased, and to overcome that previous state of affairs since it was found -and still is find - many local problems poorly resolved, moderately resolved, and many unresolved: that is, an existing social resilience test will have to be redesigned and strengthened - product of the prolonged Colombian social conflict partially overcome by a successful peace process - from local technoscience; As Markus Brunnermeier - German economist and professor of economics at Princeton University - indicates in his book The Resilient Society...The question is not to foresee everything but to be able to react...learn to recover quickly.Bogot

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
