RESUMEN

As the global public health community continues to reflect and recover from the COVID-19 pandemic, noncommunicable diseases (NCDs), and mental health and neurological conditions remains one of the largest unmet gaps in progress towards meeting the Sustainable Development Goals (SDG). People living with these health conditions, particularly among those most marginalized, acutely understand the impact of these failures in global action and investment. Integrating lived experience into the NCD and mental health response can act as an accelerator for action. Through a participatory process to co-create the WHO Framework on Meaningful Engagement on NCDs, and Mental Health and Neurological Conditions, we conducted a mixed methods and semi-structured approach, including informal consultations, focus groups, in-depth interviews, online surveys, and a short film series, that captured the perspectives of 700 individuals from 111 countries, including 386 individuals with lived experience. Working alongside lived experience communities and other relevant stakeholders, we have established and co-created a set of principles, enablers and actions for operationalizing meaningful engagement, related to dignity and respect, power and equity, inclusivity and intersectionality, commitment and transparency, and institutionalization and contextualization. People with lived experience have a right to be equitably included in all levels of policy-setting, design and implementation of programs, and to have a central role in reforming and reorienting the structures and systems intended to address the complex multifactorial challenges that they face. WHO is committed to leveraging its role in global health to further operationalize meaningful engagement within WHO and its Member States.

RESUMEN

The African region of the World Health Organization (WHO) recently adopted a strategy aimed at more comprehensive care for noncommunicable diseases (NCDs) in the region. The WHO's World Health Assembly has also newly approved several ambitious disease-specific targets that raise the expectations of chronic care and plans to revise and update the NCD-Global Action Plan. These actions provide a critically needed opportunity for reflection and course correction in the global health response to NCDs. In this paper, we highlight the status of the indicators that are currently used to monitor progress towards global goals for chronic care. We argue that weak health systems and lack of access to basic NCD medicines and technologies have prevented many countries from achieving the level of progress required by the NCD epidemic, and current targets do little to address this reality. We identify gaps in existing metrics and explore opportunities to realign the targets with the pressing priorities facing today's health systems.

RESUMEN

The capability of shrimp shells or construction demolition concrete as amendments to immobilize elements, primarily Pb and Zn, generated from mine waste weathering, was investigated via standard batch leaching test (L/S 10 cm3/g, 24 h). The effect of the amendment was tested at waste rock-to-residue ratios 9:1, 9.5:0.5, and 9.8:0.2 (weight:weight, w/w), with seawater as leachant. The effect of freshwater vs. seawater on the leaching pattern was investigated. The elemental contents of rock varied largely. Elemental levels in shells and concrete had much lower values than waste rock. Leaching results showed that amendment in both cases had high capacity to immobilize Pb and Zn. A decrease of concrete-to-rock ratio from 1:9 to 0.2:9.8 (w/w) led to more leaching of Pb but less of Zn. Similarly, decreasing shrimp-to-rock ratio increased and decreased leaching of Pb and Zn, respectively. Increasing experimental time to 5 and 10 d in a shrimp-amended batch caused less leaching of Pb and more of Zn. Both Pb and Zn immobilization in the concrete amendment was considered due to the increase of pH by concrete amending. The Pb leaching in the present study was considered controlled primarily by a sorption process, whilst the leaching for Zn might have been influenced by other factors such as pH and DO. Pb leaching from rock was much higher in seawater than in freshwater, with same range for Zn leaching, irrespective of leachant. It showed consistence between the laboratory data and the field conditions. Calculation procedures were established for amendment to mitigate mine drainage.

RESUMEN

Polonium-210 (210Po) is a radionuclide sentinel as it bioaccumulates in marine organisms, thereby being the main contributor to committed dietary doses in seafood consumers. Although seafood and marine mammals are an important part of the traditional Inuit diet, there is a general lack of information on the 210Po concentrations in the Greenlandic marine food chain leading to the human consumer. Here, we determine background 210Po concentrations in edible parts of different marine organisms from Greenland and provide a dose assessment. Blue mussels (Mytilus edulis), organs of ringed seal (Pusa hispida) and polar bear (Ursus maritimus) displayed significantly elevated 210Po concentrations in respect to all other studied organisms (p < 0.001). 210Po concentrations ranged from 0.02 Bq kg-1, w.w. in Greenland halibut (Reinhardtius hippoglossoides) muscle to 78 Bq kg-1, w.w. and 202 Bq kg-1, w.w. in ringed seal muscle and kidneys, respectively. 210Po concentration ratio for edible parts increases in the order bladderwrack (Fucus Vesiculosus), northern shrimp (Pandalus borealis), blue mussels, and from fish species to ringed seal and polar bear. 210Po distribution in fish, ringed seal, and polar bear follows a general pattern, the lowest concentrations were in muscle, and the highest concentrations were in the organs involved in metabolism. The derived 210Po annual absorbed dose in edible parts of studied marine organisms are several orders of magnitude lower than the recommended dose rate screening value of 10 µGy h-1. Effective doses from intake of 210Po to Greenland average children (1.4 mSv y-1), and high seafood and marine mammal consumers (2 mSv y-1 for adults and 3.6 mSv y-1 for children) are higher than the world average annual effective dose due to ingestion of naturally occurring radionuclides.

RESUMEN

Climatic impacts are especially pronounced in the Arctic, which as a region is warming twice as fast as the rest of the globe. Here, we investigate how mean climatic conditions and rates of climatic change impact parasitoid insect communities in 16 localities across the Arctic. We focus on parasitoids in a widespread habitat, Dryas heathlands, and describe parasitoid community composition in terms of larval host use (i.e., parasitoid use of herbivorous Lepidoptera vs. pollinating Diptera) and functional groups differing in their closeness of host associations (koinobionts vs. idiobionts). Of the latter, we expect idiobionts-as being less fine-tuned to host development-to be generally less tolerant to cold temperatures, since they are confined to attacking hosts pupating and overwintering in relatively exposed locations. To further test our findings, we assess whether similar climatic variables are associated with host abundances in a 22 year time series from Northeast Greenland. We find sites which have experienced a temperature rise in summer while retaining cold winters to be dominated by parasitoids of Lepidoptera, with the reverse being true for the parasitoids of Diptera. The rate of summer temperature rise is further associated with higher levels of herbivory, suggesting higher availability of lepidopteran hosts and changes in ecosystem functioning. We also detect a matching signal over time, as higher summer temperatures, coupled with cold early winter soils, are related to high herbivory by lepidopteran larvae, and to declines in the abundance of dipteran pollinators. Collectively, our results suggest that in parts of the warming Arctic, Dryas is being simultaneously exposed to increased herbivory and reduced pollination. Our findings point to potential drastic and rapid consequences of climate change on multitrophic-level community structure and on ecosystem functioning and highlight the value of collaborative, systematic sampling effort.

RESUMEN

PURPOSE: Misinformation and lack of information about cancer and its treatment pose significant challenges to delivering cancer care in resource-limited settings and may undermine patient engagement in care. We aimed to investigate patients' knowledge and attitudes toward cancer and its treatment and to adapt, implement, and evaluate a low-literacy cancer patient education booklet at the Hôpital Universitaire de Mirebalais (HUM) in rural Haiti. MATERIALS AND METHODS: A low-literacy cancer patient education booklet was adapted into Haitian Creole in collaboration with clinicians at HUM. Patients were recruited for structured interviews (n = 20) and two focus groups (n = 13) designed to explore patients' attitudes toward cancer and its treatment and to assess whether the booklet increased patients' knowledge via an investigator-designed knowledge test. RESULTS: Participants reported a subjective lack of knowledge about cancer and its treatments and described views of cancer as deadly or incurable. Patients of varying education levels valued receiving written materials that set expectations about cancer treatment and expressed a desire to share the booklet with caregivers and others in their community. Participants across all levels of education significantly increased their performance on a knowledge test after counseling using the booklet (p < .001). CONCLUSION: We found that an educational booklet about cancer developed in collaboration with local providers was well received by patients with variable literacy levels and improved their knowledge of cancer and its treatment in a resource-limited setting. Such educational materials have the potential to serve as tools to engage patients with cancer and their families in care. IMPLICATIONS FOR PRACTICE: Misinformation and lack of information pose significant challenges to delivering cancer care in resource-limited settings; however, there are often no culturally and literacy appropriate tools available to aid in patient education. This article shows that written educational materials are well received by patients of variable literacy levels and can be effective tools for increasing patients' knowledge of cancer and its treatment in a limited-resource setting. Furthermore, the authors have made their educational booklet, Cancer and You, freely available online and welcome the opportunity to connect with readers of The Oncologist interested in implementing this educational booklet in clinical care.

RESUMEN

Although good quality DNA can be recovered from the base of the calamus of freshly sampled feathers, as from other fully keratinized tissues such as nail or hair shaft, the quality and quantity of DNA in the majority of feather structures is much poorer. Little research has been performed to characterize the quality of this DNA is, and thus what a researcher might be able to achieve when using feathers as a source of DNA. In this review, we expand on our companion article detailing the quality of DNA in nail and hair, by synthesizing published, and new preliminary genetic data obtained from feathers. As with nail and hair, we demonstrate that although DNA can, in general, be recovered from all parts of the feather, the quality of such DNA varies. As such, although one can expect a priori that genetic analyses are possible on the feather, for PCR based analyses, it is extremely difficult to predict the size of amplicon that can be used in such analyses. However, PCR-free genetic analyses that can exploit much smaller DNA fragments may promise to be a powerful tool for future exploitation.

RESUMEN

Keratinous tissues such as nail, hair, horn, scales and feather have been used as a source of DNA for over 20 years. Particular benefits of such tissues include the ease with which they can be sampled, the relative stability of DNA in such tissues once sampled, and, in the context of ancient genetic analyses, the fact that sampling generally causes minimal visual damage to valuable specimens. Even when freshly sampled, however, the DNA quantity and quality in the fully keratinized parts of such tissues is extremely poor in comparison to other tissues such as blood and muscle - although little systematic research has been undertaken to characterize how such degradation may relate to sample source. In this review paper we present the current understanding of the quality and limitations of DNA in two key keratinous tissues, nail and hair. The findings indicate that although some fragments of nuclear and mitochondrial DNA appear to be present in almost all hair and nail samples, the quality of DNA, both in quantity and length of amplifiable DNA fragments, vary considerably not just by species, but by individual, and even within individual between hair types.

RESUMEN

Owing to exceptional biomolecule preservation, fossil avian eggshell has been used extensively in geochronology and palaeodietary studies. Here, we show, to our knowledge, for the first time that fossil eggshell is a previously unrecognized source of ancient DNA (aDNA). We describe the successful isolation and amplification of DNA from fossil eggshell up to 19 ka old. aDNA was successfully characterized from eggshell obtained from New Zealand (extinct moa and ducks), Madagascar (extinct elephant birds) and Australia (emu and owl). Our data demonstrate excellent preservation of the nucleic acids, evidenced by retrieval of both mitochondrial and nuclear DNA from many of the samples. Using confocal microscopy and quantitative PCR, this study critically evaluates approaches to maximize DNA recovery from powdered eggshell. Our quantitative PCR experiments also demonstrate that moa eggshell has approximately 125 times lower bacterial load than bone, making it a highly suitable substrate for high-throughput sequencing approaches. Importantly, the preservation of DNA in Pleistocene eggshell from Australia and Holocene deposits from Madagascar indicates that eggshell is an excellent substrate for the long-term preservation of DNA in warmer climates. The successful recovery of DNA from this substrate has implications in a number of scientific disciplines; most notably archaeology and palaeontology, where genotypes and/or DNA-based species identifications can add significantly to our understanding of diets, environments, past biodiversity and evolutionary processes.
