Geografia da (in)segurança no município de Guimarães
Dissertação de mestrado em Geografia (área de especialização em Planeamento e Gestão do Território)A criminalidade em meio urbano é um tema relevante para a população
portuguesa, conduzindo a alterações mais ou menos significativas das suas rotinas
diárias, de modo a sentir-se mais segura. O município de Guimarães tem sido estudado
em vários domínios sociais e culturais, mas sabe-se muito pouco sobre a problemática
da criminalidade e sobre o sentimento de insegurança. Atualmente pode-se afirmar que
a criminalidade pode ser atenuada ou inconscientemente potencializada, pela disposição
da malha urbana, como comprovaram Jacobs (1961), Newman (1972), Jeffery (1971,
1977) e Crowe (1991), nos seus estudos desenvolvidos sobre o espaço urbano e a sua
dinâmica organizacional.
Tendo em consideração esta perspetiva, resolvemos investigar a atual situação
do município de Guimarães face aos crimes de furto e roubo, tentando compreender de
que modo estes comportamentos infratores influenciam as rotinas dos cidadãos. Todos
os indivíduos desenvolvem mapas mentais dos espaços em que se deslocam
frequentemente e o objetivo é perceber quais são os espaços considerados por eles como
perigosos para a população.
Para tal, dividimos a nossa investigação em duas partes de investigação. A
primeira está relacionada com a análise de 9.970 queixas/denúncias deportadas à
Guarda Nacional Republicana, bem como à Polícia de Segurança Pública, entre os anos
de 2009 e 2012. A segunda parte refere-se à análise de 200 inquéritos feitos em 2013 à
população do município de Guimarães.
Os inquéritos realizados permitem-nos concluir que a noção de aumento de
criminalidade está bem patente na perceção dos cidadãos vimaranenses em relação aos
últimos anos.The criminality in the urban environment is a relevant theme to Portuguese
population, leading to more or less significant alterations of their daily routines, in order
to fill more secure. The municipality of Guimarães has been studied in various social
and cultural domains, but very little is known about the problems of crime and the
feeling of insecurity. Currently it can be affirmed that the crime can be mitigated or
unconsciously potentized by the urban grid, as proved Jacobs (1961), Newman (1972),
Jeffery (1971, 1977) and Crowe (1991) in their studies about the urban space and its
organizational dynamics.
Taking in consideration this perspective we decided to investigate the current
situation of the municipality of Guimarães comparing crimes of burglary and theft, and
trying to understand how to the crime can influence the routines of citizens. All
individuals develop mental maps of spaces they use and the goal of this dissertation is to
understand which areas are considered by population as dangerous.
For this end, we have divided our investigation into two parts. One is related, to
the analysis of 9,970 complaints/complaints recorded by the National Republican Guard
as well as by the Public Security Police, between 2009 and 2012. The second part refers
to the analysis of 200 surveys applied in 2013 to population of the municipality of
Guimarães.
The surveys allowed us to conclude that the notion of crime increase is evident in the
perception of vimaranenses citizens taking into account the more recent years
Geographical Information Systems: the past, present and future
The main challenges of the XXI century are caused by the large amount of geospatial information through a GIS. Throughout time there have been many attempts to define Geographic Information Systems (GIS). Yet there is still no consensus on its definition and to restrict it to one is limited. In the acronym - Geographic Information Systems - geographic refers to the Earth's surface and near-surface, therefore, all human production and activity, as well as non-human are possible to spatialize using GIS.info:eu-repo/semantics/publishedVersio

Genetic ablation of inositol 1,4,5-Trisphosphate receptor type 2 (IP3R2) fails to modify disease progression in a mouse model of Spinocerebellar Ataxia type 3
Spinocerebellar ataxia type 3 (SCA3) is a rare neurodegenerative disease caused by an abnormal polyglutamine expansion within the ataxin-3 protein (ATXN3). This leads to neurodegeneration of specific brain and spinal cord regions, resulting in a progressive loss of motor function. Despite neuronal death, non-neuronal cells, including astrocytes, are also involved in SCA3 pathogenesis. Astrogliosis is a common pathological feature in SCA3 patients and animal models of the disease. However, the contribution of astrocytes to SCA3 is not clearly defined. Inositol 1,4,5-trisphosphate receptor type 2 (IP3R2) is the predominant IP3R in mediating astrocyte somatic calcium signals, and genetically ablation of IP3R2 has been widely used to study astrocyte function. Here, we aimed to investigate the relevance of IP3R2 in the onset and progression of SCA3. For this, we tested whether IP3R2 depletion and the consecutive suppression of global astrocytic calcium signalling would lead to marked changes in the behavioral phenotype of a SCA3 mouse model, the CMVMJD135 transgenic line. This was achieved by crossing IP3R2 null mice with the CMVMJD135 mouse model and performing a longitudinal behavioral characterization of these mice using well-established motor-related function tests. Our results demonstrate that IP3R2 deletion in astrocytes does not modify SCA3 progression.This work has been funded by National funds, through the Foundation for Science and Technology (FCT)—project UIDB/50026/2020 and UIDP/50026/2020, PTDC/NEUNMC/3648/2014 and COMPETE-FEDER (POCI-01-0145-FEDER-016818); fellowships to DCG (2021.08121.BD), DMF (SFRH/BD/147947/2019), JSC (SFRH/BD/140624/2018), ANC (SFRH/BPD/118779/2016), AVF (UMINHO/BIL-CNCG/2022/11), SGG (SFRH/BD/101298/2014), and JFV (2020.05109.BD); FCT Scientific Employment Stimulus (CEEC)—Individual Call position to SDS (CEECIND/00685/2020); grants from the Bial Foundation (037/18) and “the la Caixa” Foundation (LCF/PR/HR21/52410024) to JFO; and by the projects NORTE-01-0145-FEDER-000013 and NORTE-01-0145-FEDER-000023, supported by the Norte Portugal Regional Operational Programme (NORTE 2020), under the PORTUGAL 2020 Partnership Agreement, through the European Regional Development Fund (ERDF).

Arbustus unedo essence: morphological and genetic characterization of the strawberry tree of Castelo de Paiva
O medronheiro é um arbusto da região mediterrânica que pode ser encontrada por todo
o país. Ao contrário do que verifica na região sul do país, no concelho de Castelo de Paiva
é atribuída uma reduzida importância económica a esta espécie. Com o intuito de
preservar e potenciar a produção desta espécie e contribuir para a dinamização da
economia do concelho, procedeu-se à caracterização morfológica e genética de uma
amostra da população de medronheiros de Castelo de Paiva. A caracterização
morfológica e genética foi realizada para um total de 10 genótipos. Para tal recolheram-se
70 folhas aleatoriamente em cada árvore. Em 40 folhas mediu-se o comprimento, largura,
comprimento do pedúnculo, peso fresco, peso seco e determinou-se a área foliar. Dos
caracteres morfológicos analisados, aqueles que se revelaram mais úteis na distinção dos
vários genótipos foram: comprimento do pedúnculo, peso fresco e peso seco. As
restantes 30 folhas foram utilizadas para a caracterização genética. Esta caracterização foi
realizada recorrendo a um marcador de DNA, ISSR. Os 5 primeiros exemplaresutilizados
na técnica de ISSR demonstraram-se polimórficos. Os resultados da caracterização
genética sugerem que a variabilidade genética na população é média a alta.The strawberry tree is a shrub native in the Mediterranean region and it can be found
throughout Portugal. Unlike the case in the southern region of the country, in Castelo de
Paiva a minor economic importance is given to this species. In order to preserve, to
enhance the production of this species and to contribute to the boosting of the economy
of the region, we proceeded to the characterization of a small sample population of this
fruit tree of Castelo de Paiva in what concerns to its morphology and genetics. The
morphological and genetic characterization was performed for a total of 10 genotypes.
For this, 70 leaves were randomly collected from each tree. For 40 leaves, it was
measured the length, the width, the peduncle length, the wet weight, the dry weight and
determined the leaf area. Of the morphological characteristics analyzed, the ones that proved most useful in distinguishing the various genotypes were: the length peduncle, the
wet weight and the dry weight. The remaining 30 leaves were used in the genetic
characterization. This characterization was performed using a DNA marker, the ISSR.
The 5 primers used in the ISSR technique proved to be polymorphic. The results from
the genetic characterization suggest that variability in population genetics is medium to
high
uma análise transversal
Publisher Copyright: Copyright © Ordem dos Médicos 2022.Introduction: Pre-exposure prophylaxis (PrEP) has gained relevance as a method of prevention for HIV in certain people and settings. Following the publication of the guideline on PrEP prescribing in Portugal, we aimed to assess the knowledge of Portuguese Medical Students about PrEP. Material and Methods: An online survey was sent to Medical students of Portuguese Medical Schools. We conducted a descriptive analysis of the results and an analytic cross-sectional study to identify factors associated with “knowing about PrEP”, “having had one class about PrEP” and “identifying eligible groups correctly”. Results: Of the 796 students that responded to the survey, 64.6% were aware of what PrEP is. Of these, 34.44% acquired this knowledge during their training. Out of the total amount of respondents, 4.77% could identify correctly and completely the eligible groups for PrEP. As the training years went by, the probability of being aware of PrEP, having had one class about PrEP, and identifying the eligible groups correctly, increased. Of the sixth-year students, 43.48% had had one class about PrEP and among the students that were aware of PrEP, 28% identified what the eligible groups were. After adjusting for the school year, we found differences between Medical Schools regarding the outcomes. The association between the different ways of knowing about PrEP and the ability to correctly identify eligible groups for PrEP was not statistically significant. Conclusion: The differences between Medical Schools could be harmonized through changes in the medical curricula that would allow for this topic to be addressed more often.publishersversionpublishe
MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugal
Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation. The spatial uncertainty of most records ranges between 0 and100 m (76%). Rodentia (n=31,573) has the highest number of records followedby Chiroptera (n=18,857), Carnivora (n=18,594), Lagomorpha (n=17,496),Cetartiodactyla (n=11,568) and Eulipotyphla (n=7008). The data setincludes records of species classified by the IUCN as threatened(e.g.,Oryctolagus cuniculus[n=12,159],Monachus monachus[n=1,512],andLynx pardinus[n=197]).

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study
Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
