The effectiveness of mindfulness for the management of anxiety in the nursing staff: Systematic review and meta-analysis.

A systematic review with meta-analysis following Joanna Briggs Institute recommendations. It aimed to determine the effectiveness of mindfulness for the management of anxiety symptoms in the nursing staff and stress as a secondary outcome. The databases searched were MEDLINE, Embase, LILACS, CINAHL, Web of Science, Scopus and Psycinfo. Search was conducted in October 2022. Independent reviewers used standardized methods to research, track, and code the included studies. Data meta-analysis was performed using random effects models. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) was used as an approach to assess the quality and certainty of evidence in research studies. The review examined the effectiveness of mindfulness on nursing staff in 13 studies. The meta-analysis revealed a statistically significant decrease in anxiety and stress after treatment, with an average reduction of 0.36 in anxiety and 0.48 in stress. The results emphasizes the possibility of mindfulness being an effective intervention to the management of anxiety and stress in nursing staff. However, the studies analyzed presented limitations in the design and sampling in the development of the intervention, which impact the conclusive statements about the effectiveness of mindfulness and the generalization of the results. The implications to the nursing field involve adopting evidence-based research and practices to improve the well-being and quality of life of nursing professionals, as well as strengthening the evidence base surrounding mindfulness interventions in nursing practice. This may lead to changes in healthcare policies, care practices, and recognition of the importance of nurses' well-being for effective healthcare delivery.

Predicting the distribution and abundance of abandoned, lost or discarded fishing gear (ALDFG) in the deep sea of the Azores (North Atlantic).

Abandoned, lost, or discarded fishing gear (ALDFG), represents a significant percentage of the global plastic pollution, currently considered one of the major sources from sea-based activities. However, there is still limited understanding of the quantities of ALDFG present on the seafloor and their impacts. In this study, data on the presence of ALDFG was obtained from a large archive of seafloor video footage (351 dives) collected by different imaging platforms in the Azores region over 15 years (2006-2020). Most ALDFG items observed in the images relate to the local bottom longline fishery operating in the region, and include longlines but also anchors, weights, cables and buoys. A generalized additive mixed model (GAMM) was used to predict the distribution and abundance of ALDFG over the seafloor within the limits of the Azores Exclusive Economic Zone (EEZ) using a suite of environmental and anthropogenic variables. We estimated an average of 113 ± 310 items km-2 (597 ± 756 per km-2 above 1000 m depth), which could imply that over 20 million ALDFG items are present on the deep seafloor of the Azores EEZ. The resulting model identified potential hotspots of ALDFG along the seabed, some of them located over sensitive benthic habitats, such as specific seamounts. In addition, the interactions between ALDFG and benthic organisms were also analysed. Numerous entanglements were observed with several species of large anthozoans and sponges. The use of predictive distribution modelling for ALDFG should be regarded as a useful tool to support ecosystem-based management, which can provide indirect information about fishing pressure and allow the identification of potential high-risk areas. Additional knowledge about the sources, amounts, fates and impacts of ALDFG will be key to address the global issue of plastic pollution and the effects of fishing on marine ecosystems.

Dense cold-water coral garden of Paragorgia johnsoni suggests the importance of the Mid-Atlantic Ridge for deep-sea biodiversity.

Mid-ocean ridges generate a myriad of physical oceanographic processes that favor the supply of food and nutrients to suspension- and filter-feeding organisms, such as cold-water corals and deep-sea sponges. However, the pioneering work conducted along the Mid-Atlantic Ridge failed to report the presence of large and dense living coral reefs, coral gardens, or sponge aggregations. Here, we describe the densest, near-natural, and novel octocoral garden composed of large red and white colonies of Paragorgia johnsoni Gray, 1862 discovered at 545-595 m depth on the slopes of the Mid-Atlantic Ridge, in the Azores region. This newly discovered octocoral garden is a good candidate for protection since it fits many of the FAO criteria that define what constitutes a Vulnerable Marine Ecosystem. The observations described here corroborate the existence of a close relationship between the octocoral structure and the ambient currents on ridge-like topographies, providing new insights into the functioning of mid-ocean ridges' ecosystems. The ubiquitous presence of biogenic and geological topographies associated with mid-ocean ridges, which could act as climate refugia, suggests their global importance for deep-sea biodiversity. A better understanding of the processes involved is, therefore, required. Our observations may inspire future deep-sea research initiatives to narrow existing knowledge gaps of biophysical connections with benthic fauna at small spatial scales along mid-ocean ridges.

Hidrocefalia aguda: uma revisão bibliográfica / Acute hydrocephalus: a bibliographic review

Introdução: o diagnóstico de hidrocefalia é dado de acordo com o quadro clínico, que geralmente se correlaciona com o achado tomográfico de dilatação do sistema ventricular (ventriculomegalia). A definição de tal condição é definida através do Índice de Evans, que se dá pela razão da maior distância entre as extremidades dos cornos anteriores dos ventrículos laterais pela maior distância entre os hemisférios cerebrais. Objetivo: revisar a fisiopatologia da hidrocefalia aguda, suas apresentações clínicas e condutas que proporcionem uma melhor resolução do quadro dessa emergência neurocirúrgica. Método: informações obtidas através de revisão bibliográfica. Considerações finais: a análise bibliográfica demonstra a importância do rápido diagnóstico da hidrocefalia aguda, suas apresentações clínicas, as melhores condutas a serem definidas para que possam beneficiar a saúde do paciente, porque as consequências geradas pelo aumento da pressão intracraniana podem causar danos irreversíveis.

Introduction: the diagnosis of hydrocephalus is given according to the clinical picture, which usually correlates with the tomographic findings of dilation of the ventricular system (ventriculomegaly). The definition of such condition is defined by the Evans Index, which is given by the ratio of the greater distance between the extremities of the anterior horns of the lateral ventricles by the greater distance between the cerebral hemispheres. Objectives: review the pathophysiology of acute hydrocephalus, its clinical presentations and conducts that provide a better resolution of that neurosurgical emergency. Methods: information obtained through a bibliographic review. Final considerations: the bibliographic review demonstrates the importance of the faster diagnosis of acute hydrocephalus, its clinical presentations and a better resolution to be define a way that could be benefit to patient's health, because the consequences generated by intracranial high-levels pressure can cause irreversible damage.

The collection of birds from Mozambique at the Instituto de Investigação Científica Tropical of the University of Lisbon (Portugal).

The Instituto de Investigação Científica Tropical of the University of Lisbon, which resulted from the recent merger (in 2015) of the former state laboratory Instituto de Investigação Científica Tropical in the University of Lisbon, holds an important collection of bird skins from the Portuguese-speaking African Countries (Angola, Mozambique, São Tomé and Príncipe, Guinea Bissau and Cape Verde), gathered as a result of several scientific expeditions made during the colonial period. In this paper, the subset from Mozambique is described, which was taxonomically revised and georeferenced. It contains 1585 specimens belonging to 412 taxa, collected between 1932 and 1971, but mainly in 1948 (43% of specimens) and 1955 (30% of specimens). The collection covers all eleven provinces of the country, although areas south of the Zambezi River are better represented than those north of the river. The provinces with the highest number of specimens were Maputo, Sofala, and Gaza. Although it is a relatively small collection with a patchy coverage, it adds significantly to Global Biodiversity Information Facility, with 15% of all records available before and during the collecting period (1830-1971) being the second largest dataset for that period for Mozambique.

The collection of birds from São Tomé and Príncipe at the Instituto de Investigação Científica Tropical of the University of Lisbon (Portugal).

The former Instituto de Investigação Científica Tropical-IICT (Lisbon, Portugal), recently integrated into the University of Lisbon, gathers important natural history collections from Portuguese-speaking African countries. In this study, we describe the bird collection from the Democratic Republic of São Tomé and Príncipe, which was fully taxonomically checked and georeferenced. The IICT bird collection contains 5598 specimens, of which 559 are from São Tomé and Príncipe, representing 85 taxa, including 19 endemic species and 13 endemic subspecies of birds. The specimens were collected between 1946 and 1973, although 43% of the records are from 1954 and 45% are from 1970. The geographic distribution of samples covers the whole territory, with a higher number of records from São Tomé than from Príncipe. The districts with highest number of records are Pagué (equivalent to Príncipe Island), and Água Grande and Mé-Zochi on São Tomé. Despite the relatively low number of specimens per taxon, the importance of the collection is considerable due to the high number of endemic and threatened species represented. Furthermore, it adds valuable information to the GBIF network, especially for a country whose two islands are each an Endemic Bird Area and for which substantial gaps in ornithological knowledge remain.

The collection and database of Birds of Angola hosted at IICT (Instituto de Investigação Científica Tropical), Lisboa, Portugal.

The bird collection of the Instituto de Investigação Cientítica Tropical (Lisbon, Portugal) holds 5598 preserved specimens (skins), mainly from Angola, Mozambique, Guinea-Bissau, São Tomé and Principe, and Cape Verde. The subset collection from Angola includes 1560 specimens, which were taxonomically revised and georeferenced for the publication of this data paper. The collection contains a total of 522 taxa, including 161 species and 361 subspecies. Two species are classified by the IUCN Red List as Endangered - the wattled crane (Grus carunculata) and the Gabela bush-shrike (Laniarius amboimensis) - and two are classified as vulnerable - African penguin (Spheniscus demersus) and the white-headed vulture (Trigonoceps occipitalis). The temporal span of the database ranges between 1943 and 1979, but 32% are from years 1958-1959, and 25% from years 1968-1969. The spatial coverage of the collection is uneven, with 2/3 of the records representing only four of the eighteen provinces of the country, namely Huíla, Moxico, Namibe and Cuanza Sul. It adds, however, valuable information for the Huíla area of the Angolan Scarp, which is probably a biodiversity hotspot of global conservation priority. Furthermore, this georeferenced database adds invaluable bird information to the GBIF network, for one of the countries with highest but less known biodiversity in Africa.
