Life cycle and biological parameters of several Brazilian Amazon fish species
This contribution summarizes knowledge on the biology (population dynamics, reproduction, ecology) of 25 fish species from the Lower Amazon, Brazil, based on data from a Brazilian-German field project (IARA) and a review of the literature

Evaluating the Effectiveness and Cost-Effectiveness of Seizure Dogs in Persons With Medically Refractory Epilepsy in the Netherlands
__Background:__ Epilepsy is associated with a high disease burden, impacting the lives of
people with epilepsy and their caregivers and family. Persons with medically refractory
epilepsy experience the greatest burden, suffering from profound physical, psychological,
and social consequences. Anecdotal evidence suggests these persons may benefit
from a seizure dog. As the training of a seizure dog is a substantial investment,
their accessibility is limited in the absence of collective reimbursement as is seen
in the Netherlands. Despite sustained interest in seizure dogs, scientific knowledge
on their benefits and costs remains scarce. To substantiate reimbursement decisions
stronger evidence is required. The EPISODE study aims to provide this evidence
by evaluating the effectiveness and cost-effectiveness of seizure dogs in adults with
medically refractory epilepsy.
__Methods:__ The study is designed as a stepped wedge randomized controlled trial that
compares the use of seizure dogs in addition to usual care, with usual care alone. The
study includes adults with epilepsy for whom current treatment options failed to achieve
seizure freedom. Seizure frequency of participants should be at least two seizures per
week, and the seizures should be associated with a high risk of injury or dysfunction.
During the 3 year follow-up period, participants receive a seizure dog in a randomized
order. Outcome measures are taken at multiple time points both before and after receiving
the seizure dog. Seizure frequency is the primary outcome of the study and will be
recorded continuously using a seizure diary. Questionnaires measuring seizure severity,
quality of life, well-being, resource use, productivity, social participation, and caregiver
burden will be completed at baseline and every 3 months thereafter. The study is
designed to include a minimum of 25 participants.
__Discussion:__ This protocol describes the first randomized controlled trial on seizure
dogs. The study will provide comprehensive data on the effectiveness and cost effectiveness
of seizure dogs in adults with medically refractory epilepsy. Broader benefits
of seizure dogs for persons with epilepsy and their caregivers are taken into account,
as well as the welfare of the dogs. The findings of the study can be used to inform
decision-makers on the reimbursement of seizure dogs

Pervasive gaps in Amazonian ecological research
Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4
While the increasing availability of global databases on ecological communities has advanced our knowledge
of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In
the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of
Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus
crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced
environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian
Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by
2050. This means that unless we take immediate action, we will not be able to establish their current status,
much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
