Ambiente virtual de aprendizagem no âmbito das feridas crónicas
As feridas crónicas, dadas as suas repercussões pessoais, familiares e socio-económicas, representam
um grave problema de saúde em todo o mundo. Actualmente está disponível uma grande variedade de produtos
e equipamentos para o seu tratamento, o que obriga um enorme rigor nos critérios de selecção. A escolha
criteriosa do produto e procedimentos mais adequados depende do correcto diagnóstico e caracterização da
ferida crónica. Com o objectivo de melhorar o processo de formação no âmbito das feridas crónicas, aumentando
a componente de práticas simuladas, desenvolveu-se ambiente virtual online (e-fer) que permite a elaboração
de casos virtuais de pessoas com feridas crónicas, integrando informação pictórica (fotografia) e não pictórica
(evolução, localização, tamanho, tunelização, edema, enduração, odor, exudado, dor) da ferida, dados sóciodemográficos,
antecedentes de saúde, status de mobilidade e opções de diagnostica e tratamento correctas.
Existe um grupo de especialistas de âmbito nacional, responsável pela construção dos casos. Cada caso representa
uma descrição rigorosa de experiências profissionais vivenciadas em contexto real e requer uma análise muito
cuidada da informação disponibilizada. Os formandos acedem online ao e-fer para diagnosticar e tratar os casos
virtuais. É dado feedback específico, como bases nas opções tomadas. Paralelamente partilham num fórum as
suas dúvidas e sugestões (contextualizadas nos casos virtuais que estão a resolver) com os outros formandos e
especialistas (tutores online)
Fisher's perceptions about a marine protected area over time
The perceptions of fishers towards the Arrábida Marine Park, a marine protected area (MPA) in the west coast of
Portugal, were studied through face-to-face interviews in two different moments of the MPA life cycle. Fishers'
perceptions about the MPA and the impact it had on the fishing activity over time were identified just before the
full implementation of the zoning and regulations of the management plan and 10 years later. This study aimed
to investigate fishers' knowledge, acceptance and perceptions about the MPA changed with time, if support for
the MPA was linked to the impact of the MPA on the fishing activity, and if fishers' perceptions about the impact
of the MPA on the fishing activity match with local landings trends. Results show that although knowledge about
the marine park significantly improved over time, fishers' acceptance did not. A decrease on fishers' support was
not substantial but occurred. Issues such as the disagreement with regulations reinforced concerns raised during
the implementation of the marine park, particularly in relation to the top-down decision-making, which commonly
confers minor participation, recognition and legitimacy to fishers. Apparently, fisheries benefits were still
not perceived by local fishers, though they are central for fishers' support. Further, the perceived negative
impacts of the park seemed to be more related to social aspects and individual interests than to impacts on
catches. Addressing adequate management, enforcement and participation of local fishers is still possible and are
advocated here as to contribute to the expected socioecological outcomes and respective support, leading to the
future successful performance of the Arrábida Marine Park. Assessing fishers’ perceptions towards an MPA over
time is central and should be included on periodical socioecological monitoring and inform an effective adaptive

Sex differences in the dorsolateral telencephalon correlate with home range size in blenniid fish
Blenniid fish exhibit a polygynandric mating system with parental
care restricted to males. Nest-holder males defend a
breeding territory centered on their nest, usually a crevice or
hole in a rocky substrate, to which they attract females to
spawn. Females, on the other hand, must search for nests in
order to spawn and usually are the choosy sex, producing
several sequential egg batches and broods during the breeding
season. Therefore, male blennies are more site-attached
than females. This situation offers an opportunity to investigate
potential neural correlates of intraspecific differences in
selective pressures for different spatial abilities in these species.
Since the dorsolateral telencephalon has been considered
a teleost homologue of the mammalian hippocampus,
we predicted that the spatial abilities required for females to
locate and return accurately to nests of males may have produced
a sex difference in the size of the telencephalic nuclei
involved in spatial abilities, biased towards females. To
test this hypothesis, we assessed the home ranges and measured
the size of the dorsolateral telencephalon of both sexes during the breeding season in two blenniid species, the
shanny (Lipophrys pholis) and the Azorean rock-pool blenny
(Parablennius parvicornis) . We chose these two species because
they differ in the degree of chemical communication
they use, and this could also lead to differences in telencephalic
areas. As predicted, in both species females present
considerably larger home ranges paralleled by larger dorsolateral
ventral telencephalic nuclei (DLv) than males. Other
telencephalic nuclei that were measured did not show any
sex difference in size. These results suggest that the DLv is
involved in spatial abilities in blenniid fish and that sexual
selection may be promoting this divergence as already described
for mammals and birds
Co-design of a marine protected area zoning and the lessons learned from it
Marine Protected Areas (MPAs) are a tool to safeguard marine natural systems,
yet their effectiveness depends on how well they are integrated into the existing
socioeconomic context. Stakeholder engagement in MPA design can
contribute to increasing integration. This study focuses on the co-design of
an MPA between researchers, public administration, the private sector, and
non-governmental organizations. The proposed MPA is in Portugal and
includes an area that is a hotspot for biodiversity and economic activities.
This is the first MPA proposal in mainland Portugal co-designed using a
participatory approach. This study highlights the steps of the zoning process
and synthesizes the eight main lessons learned, useful for other cases,
particularly for relatively small coastal MPAs with multiple socioeconomic
activities. Three zoning proposals were developed and discussed within the
participatory process. The proposals considered the best scientific and local
knowledge available and were defined using ecological, socioeconomic, and
shape-area guiding principles. In an iterative manner and following a
participatory approach, compromises with stakeholders were achieved, and a
final proposal, scientifically sound and socially accepted by most stakeholders,
was delivered to the government. The final zoning plan will achieve ambitious
conservation goals, including the largest fully protected area to be declared in
mainland Portugal, while minimizing the impacts on the existing economic activities and promoting its sustainability. This process resulted in valuable
lessons that may be applied elsewhere and guide future MPA implementation
or rezoning of existing ones. These transdisciplinary and participatory
processes can be time and resource-consuming but are vital for ensuring
MPA effectiveness.Fundação para a Ciência e Tecnologia - FCTinfo:eu-repo/semantics/publishedVersio
Setting performance indicators for coastal marine protected areas: An expert-based methodology
Marine Protected Areas (MPAs) require effective indicators to assess their performance, in
compliance with the goals of relevant national and international commitments. Achieving
and prioritizing shortlists of multidisciplinary indicators demands a significant effort from
specialists to depict the multiple conservation and socioeconomic interests, and the large
complexity of natural systems. The present paper describes a structured expert-based
methodology (process and outputs) to co-define a list of multidisciplinary MPA
performance indicators. This work was promoted by the management authority of
coastal MPAs in mainland Portugal to gather a consensual and feasible list of indicators
that would guide the design of a future national monitoring program. Hence, Portuguese
coastal MPAs served as a case study to develop such a process between 2019 and 2020.
In the end, participants (1) agreed on a shortlist of prioritized indicators (i.e., environmental,
governance, and socioeconomic indicators) and (2) defined minimum monitoring
frequencies for the indicators in this list, compatible with the potential replicability of the
associated survey methods. The present approach recommends that management plans
incorporate monitoring procedures and survey methods, with a validated list of indicators
and associated monitoring periodicity, agreed among researchers, MPA managers and
governance experts. The proposed methodology, and the lessons learned from it, can
support future processes aiming to define and prioritize MPA performance indicatorsFundação para a Ciência e Tecnologia - FCT, European Maritime and

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences
The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported
by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on
18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based
researchers who signed it in the short time span from 20 September to 6 October 2016
Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil
The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others
Worldwide trends in hypertension prevalence and progress in treatment and control from 1990 to 2019: a pooled analysis of 1201 population-representative studies with 104 million participants
Background
Hypertension can be detected at the primary health-care level and low-cost treatments can effectively control hypertension. We aimed to measure the prevalence of hypertension and progress in its detection, treatment, and control from 1990 to 2019 for 200 countries and territories.
Methods
We used data from 1990 to 2019 on people aged 30–79 years from population-representative studies with measurement of blood pressure and data on blood pressure treatment. We defined hypertension as having systolic blood pressure 140 mm Hg or greater, diastolic blood pressure 90 mm Hg or greater, or taking medication for hypertension. We applied a Bayesian hierarchical model to estimate the prevalence of hypertension and the proportion of people with hypertension who had a previous diagnosis (detection), who were taking medication for hypertension (treatment), and whose hypertension was controlled to below 140/90 mm Hg (control). The model allowed for trends over time to be non-linear and to vary by age.
Findings
The number of people aged 30–79 years with hypertension doubled from 1990 to 2019, from 331 (95% credible interval 306–359) million women and 317 (292–344) million men in 1990 to 626 (584–668) million women and 652 (604–698) million men in 2019, despite stable global age-standardised prevalence. In 2019, age-standardised hypertension prevalence was lowest in Canada and Peru for both men and women; in Taiwan, South Korea, Japan, and some countries in western Europe including Switzerland, Spain, and the UK for women; and in several low-income and middle-income countries such as Eritrea, Bangladesh, Ethiopia, and Solomon Islands for men. Hypertension prevalence surpassed 50% for women in two countries and men in nine countries, in central and eastern Europe, central Asia, Oceania, and Latin America. Globally, 59% (55–62) of women and 49% (46–52) of men with hypertension reported a previous diagnosis of hypertension in 2019, and 47% (43–51) of women and 38% (35–41) of men were treated. Control rates among people with hypertension in 2019 were 23% (20–27) for women and 18% (16–21) for men. In 2019, treatment and control rates were highest in South Korea, Canada, and Iceland (treatment >70%; control >50%), followed by the USA, Costa Rica, Germany, Portugal, and Taiwan. Treatment rates were less than 25% for women and less than 20% for men in Nepal, Indonesia, and some countries in sub-Saharan Africa and Oceania. Control rates were below 10% for women and men in these countries and for men in some countries in north Africa, central and south Asia, and eastern Europe. Treatment and control rates have improved in most countries since 1990, but we found little change in most countries in sub-Saharan Africa and Oceania. Improvements were largest in high-income countries, central Europe, and some upper-middle-income and recently high-income countries including Costa Rica, Taiwan, Kazakhstan, South Africa, Brazil, Chile, Turkey, and Iran.
Interpretation
Improvements in the detection, treatment, and control of hypertension have varied substantially across countries, with some middle-income countries now outperforming most high-income nations. The dual approach of reducing hypertension prevalence through primary prevention and enhancing its treatment and control is achievable not only in high-income countries but also in low-income and middle-income settings
Global variations in diabetes mellitus based on fasting glucose and haemogloblin A1c
Fasting plasma glucose (FPG) and haemoglobin A1c (HbA1c) are both used to diagnose
diabetes, but may identify different people as having diabetes. We used data from 117
population-based studies and quantified, in different world regions, the prevalence of
diagnosed diabetes, and whether those who were previously undiagnosed and detected
as having diabetes in survey screening had elevated FPG, HbA1c, or both. We developed
prediction equations for estimating the probability that a person without previously
diagnosed diabetes, and at a specific level of FPG, had elevated HbA1c, and vice versa.
The age-standardised proportion of diabetes that was previously undiagnosed, and
detected in survey screening, ranged from 30% in the high-income western region to 66%
in south Asia. Among those with screen-detected diabetes with either test, the agestandardised
proportion who had elevated levels of both FPG and HbA1c was 29-39%
across regions; the remainder had discordant elevation of FPG or HbA1c. In most low- and
middle-income regions, isolated elevated HbA1c more common than isolated elevated
FPG. In these regions, the use of FPG alone may delay diabetes diagnosis and
underestimate diabetes prevalence. Our prediction equations help allocate finite
resources for measuring HbA1c to reduce the global gap in diabetes diagnosis and
surveillance.peer-reviewe
Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight NCD Risk Factor Collaboration (NCD-RisC)
From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions
