Evidence of semantic processing in parafoveal reading: a rapid parallel visual presentation (Rpvp) study

This study explores whether semantic processing in parafoveal reading in the Italian language is modulated by the perceptual and lexical features of stimuli by analyzing the results of the rapid parallel visual presentation (RPVP) paradigm experiment, which simultaneously presented two words, with one in the fovea and one in the parafovea. The words were randomly sampled from a set of semantically related and semantically unrelated pairs. The accuracy and reaction times in reading the words were measured as a function of the stimulus length and written word frequency. Fewer errors were observed in reading parafoveal words when they were semantically related to the foveal ones, and a larger semantic facilitatory effect was observed when the foveal word was highly frequent and the parafoveal word was short. Analysis of the reaction times suggests that the semantic relation between the two words sped up the naming of the foveal word when both words were short and highly frequent. Altogether, these results add further evidence in favor of the semantic processing of words in the parafovea during reading, modulated by the orthographic and lexical features of the stimuli. The results are discussed within the context of the most prominent models of word processing and eye movement controls in reading

In this report, we describe eight nearly complete genome sequences of rabies virus strains collected in the Democratic Republic of the Congo from domestic carnivores in 2017 and 2018. All of them clustered into a specific phylogroup among the Africa 1b lineage in the Cosmopolitan clade

Capacity building efforts for rabies diagnosis in resource-limited countries in Sub-Saharan Africa: a case report of the central veterinary laboratory in Benin (Parakou)

Rabies has been listed as a priority zoonotic disease in many African countries and the countdown to reach the goal of eliminating dog-mediated human rabies deaths by 2030 means that disease control measures need to be applied fast. In this context, an essential pillar of any national plan to control rabies is the implementation of reliable diagnostic techniques to ensure the success of field surveillance systems. Although many African countries have received international support for the control of rabies-some countries, like Benin, have not received a similar level of support. Indeed, until 2018, Benin was not able to diagnose rabies and rabies diagnosis in animals as well as humans relied solely on observed clinical symptoms. Although the Central Veterinary Laboratory (CVL) of Parakou had the equipment to implement two recommended tests, the lack of specific reagents and skills prevented the implementation of a rabies diagnostic service. Here we present the joint efforts of the national authorities in Benin, intergovernmental agencies, and non-governmental organizations to assess the strengths and weaknesses of the government's rabies control efforts. We have applied the Stepwise Approach toward Rabies Elimination (SARE) analysis, implemented rabies diagnostic capacities at the CVL of Parakou, characterized strains of rabies virus circulating in Benin, and finally integrated an inter-laboratory comparison program

From reverse innovation to global innovation in animal health: a review

Reverse innovation refers to learning from or diffusion of innovations developed in low income settings and further translated to industrialized countries. There is lack of consensus regarding terminology, but the idea that innovations in low-income countries are promising for adoption in high-income contexts is not new. However, in healthcare literature globally, the vast majority of publications referring to 'disruptive innovation' were published in the last ten years. To assess the potential of innovative developments and technologies for improving animal health, we initiated a literature review in 2020. We used a combined approach, incorporating targeted searching in PubMed using a key word algorithm with a snowball technique, to identify 120 relevant publications and extract data for qualitative coding. Heterogeneity of articles precluded meta-analysis, quality scoring and risk of bias analysis. We can distinguish technical innovations like new digital devices, diagnostic tests and procedures, and social innovations of intersectoral cooperation. We profile two case studies to describe potential global innovations: an integrated surveillance and response system in Somali Regional State, Ethiopia and a blockchain secured One Health intervention to optimally provide post-exposure prophylaxis for rabies exposed people in West Africa. Innovation follows no borders and can also occur in low-income settings, under constraints of cost, lack of services and infrastructure. Lower administrative and legal barriers may contribute to produce innovations that would not be possible under conditions of high density of regulation. We recommend using the term global innovation, which highlights those emanating from international partnership to solve problems of global implications

The promotion and development of One Health at Swiss TPH and its greater potential

One Health, an integrated health concept, is now an integral part of health research and development. One Health overlaps with other integrated approaches to health such as EcoHealth or Planetary Health, which not only consider the patient or population groups but include them in the social-ecological context. One Health has gained the widest foothold politically, institutionally, and in operational implementation. Increasingly, One Health is becoming part of reporting under the International Health Legislation (IHR 2005). The Swiss Tropical and Public Health Institute (Swiss TPH) has played a part in these developments with one of the first mentions of One Health in the biomedical literature. Here, we summarise the history of ideas and processes that led to the development of One Health research and development at the Swiss TPH, clarify its theoretical and methodological foundations, and explore its larger societal potential as an integrated approach to thinking. The history of ideas and processes leading to the development of One Health research at the Swiss TPH were inspired by far-sighted and open ideas of the directors and heads of departments, without exerting too much influence. They followed the progressing work and supported it with further ideas. These in turn were taken up and further developed by a growing number of individual scientists. These ideas were related to other strands of knowledge from economics, molecular biology, anthropology, sociology, theology, and linguistics. We endeavour to relate Western biomedical forms of knowledge generation with other forms, such as Mayan medicine. One Health, in its present form, has been influenced by African mobile pastoralists' integrated thinking that have been taken up into Western epistemologies. The intercultural nature of global and regional One Health approaches will inevitably undergo further scrutiny of successful ways fostering inter-epistemic interaction. Now theoretically well grounded, the One Health approach of seeking benefits for all through better and more equitable cooperation can clearly be applied to engagement in solving major societal problems such as social inequality, animal protection and welfare, environmental protection, climate change mitigation, biodiversity conservation, and conflict transformation

Household transmission of SARS-CoV-2 in a rural area in South Africa

Background. Patterns of SARS‐CoV‐2 spread have varied by geolocation, with differences in seroprevalence between urban and rural areas, and between waves. Household spread of SARS‐CoV‐2 is a known source of new COVID‐19 infections, with rural areas in sub‐Saharan Africa being more prone than urban areas to COVID‐19 transmission because of limited access to water in some areas, delayed health‐ seeking behaviour and poor access to care. Objectives. To explore SARS‐CoV‐2 infection incidence and transmission in rural households in South Africa (SA). Methods. We conducted a prospective household cluster investigation between 13 April and 21 July 2021 in the Matjhabeng subdistrict, a rural area in Free State Province, SA. Adults with SARS‐CoV‐2 confirmed by polymerase chain reaction (PCR) tests (index cases, ICs) and their household contacts (HCs) were enrolled. Household visits conducted at enrolment and on days 7, 14 and 28 included interviewer‐ administered questionnaires and respiratory and blood sample collection for SARS‐CoV‐2 PCR and SARS‐CoV‐2 immunoglobulin G serological testing, respectively. Co‐primary cases were HCs with a positive SARS‐CoV‐2 PCR test at enrolment. The incidence rate (IR), using the Poisson distribution, was HCs with a new positive PCR and/or serological test per 1 000 person‐days. Associations between outcomes and HC characteristics were adjusted for intra‐cluster correlation using robust standard errors. The secondary infection rate (SIR) was the proportion of new COVID‐19 infections among susceptible HCs. Results. Among 23 ICs and 83 HCs enrolled, 10 SARS‐CoV‐2 incident cases were identified, giving an IR of 5.8 per 1 000 person‐days (95% confidence interval (CI) 3.14 ‐ 11.95). Households with a co‐primary case had higher IRs than households without a co‐primary case (crude IR 14.16 v. 1.75, respectively; p=0.054). HIV infection, obesity and the presence of chronic conditions did not materially alter the crude IR. The SIR was 15.9% (95% CI 7.90 ‐ 29.32). Households with a lower household density (fewer household members per bedroom) had a higher IR (IR 9.58; 95% CI 4.67 ‐ 21.71) than households with a higher density (IR 3.06; 95% CI 1.00 ‐ 12.35). Conclusion. We found a high SARS‐CoV‐2 infection rate among HCs in a rural setting, with 48% of households having a co‐primary case at the time of enrolment. Households with co‐primary cases were associated with a higher seroprevalence and incidence of SARS‐CoV‐2. Sociodemographic and health characteristics were not associated with SARS‐CoV‐2 transmission in this study, and we did not identify any transmission risks inherent to a rural setting

First report of Echinococcus granulosus (genotype G6) in a dog in Bamako, Mali

Cystic echinococcosis is one of the most widespread and important helminthic zoonoses, caused by the larval stage of Echinococcus granulosus sensu lato. However, to date there is little information about the disease in West Africa. Faecal and fur samples from 193 dogs, the main final hosts, were collected in 2010 and 2011 in Bamako, Mali. Taeniid eggs were found microscopically in 28/118 (24%) and 80/223 (36%) faecal and fur samples, respectively. One faecal and one fur sample from the same dog were positive for E. granulosus s. l. DNA. In the remaining 27 faecal (96%) and 77 fur samples (96%) only Taenia DNA was detected. Three microscopically positive fur samples were negative by PCR. Sequence analysis of part of the NADH dehydrogenase subunit 1 gene identified the parasite as E. granulosus (genotype G6; Echinococcus canadensis). This is the first study to focus on the final host of E. granulosus s. l. in Mali and the first report of E. canadensis in Mali
