Ambient temperature and dengue hospitalization in Brazil: A 10-year period case time series analysis.

Background: Dengue has an increased worldwide epidemic potential with the global rising temperature due to climate change. Heat and rainfall are known to influence seasonal patterns of dengue transmission over the course of weeks to months. However, there is a gap in knowledge about the short-term effect of heat on dengue severity.

The Influence of Blood Titanium Levels on DNA Damage in Brazilian Workers Occupationally Exposed to Different Chemical Agents.

Occupational exposure to pollutants may cause health-damaging effects in humans. Genotoxicity assays can be used to detect the toxic effects of pollutants. In the present study, we evaluated genetic damage in three populations occupationally exposed to benzene, pyrenes, and agrochemicals and assessed the possible influence of titanium (Ti) co-exposure.

Towards Automated Semantic Segmentation in Mammography Images for Enhanced Clinical Applications.

Mammography images are widely used to detect non-palpable breast lesions or nodules, aiding in cancer prevention and enabling timely intervention when necessary. To support medical analysis, computer-aided detection systems can automate the segmentation of landmark structures, which is helpful in locating abnormalities and evaluating image acquisition adequacy. This paper presents a deep learning-based framework for segmenting the nipple, the pectoral muscle, the fibroglandular tissue, and the fatty tissue in standard-view mammography images.

When function words carry content.

Studies on eye movements during reading have primarily focussed on the processing of content words (CWs), such as verbs and nouns. Those few studies that have analysed eye movements on function words (FWs), such as articles and prepositions, have reported that FWs are typically skipped more often and, when fixated, receive fewer and shorter fixations than CWs. However, those studies were often conducted in languages where FWs contain comparatively little information (e.

The impact of social isolation on depression-like behavior in carioca high- and low-conditioned freezing rats.

This study investigated the impact of social isolation in Carioca High-Conditioned Freezing (CHF) rats, an animal model of generalized anxiety disorder (GAD). Animals selected for high (CHF), low trait anxiety (Carioca Low-Conditioned Freezing, CLF), and control rats from randomly bred populations (CTL) were housed in groups or kept isolated in their cages for 14 consecutive days. On the fifteenth day, all animals underwent the Forced Swimming Test (FST), where the latency to immobility was assessed as a depressive-like measure.

Redefining Arctic boundaries in a changing climate: interdisciplinary perspectives on governance strategies.

The Arctic rapidly transforms due to global warming and increased human activities, triggering complex changes at unprecedented speeds that challenge conventional institutional responses. We analyse these changes through the lenses of social, political, and environmental boundaries and investigate their impacts on both inhabitants' livelihoods and the region's political framework. Employing an interdisciplinary approach, we highlight the complexities of understanding the interplay among global, regional, and local dynamics in an era where human and non-human aspects are entwined.

Cross-cultural linguistic adaptation and development of three alternate forms of the Free and Cued Selective Reminding Test to the Brazilian context: The role of word familiarity.

In spite of its importance, studies presenting detailed development procedures of alternate forms of verbal memory paradigms remains limited and unclear in terms of word selection criteria, while failing to consider word familiarity factors, despite its crucial role on episodic memory retrieval and encoding mechanisms. The present study aims to present the cross-cultural linguistic adaptation and development procedures of alternate forms of the Free and Cued Selective Reminding Test to the Brazilian context (FCSRT) based on word familiarity. After translation and backtranslation procedures, 231 new words were gathered and underwent a step-by-step familiarity analysis.

Apply the Laws, if They are Good: Moral Evaluations Linearly Predict Whether Judges Should Enforce the Law.

What should judges do when faced with immoral laws? Should they apply them without exception, since "the law is the law?" Or can exceptions be made for grossly immoral laws, such as historically, Nazi law? Surveying laypeople (N = 167) and people with some legal training (N = 141) on these matters, we find a surprisingly strong, monotonic relationship between people's subjective moral evaluation of laws and their judgments that these laws should be applied in concrete cases. This tendency is most pronounced among individuals who endorse natural law (i.e.

Persistent carbapenem resistance in mechanically ventilated ICU patients: A before-and-after analysis of the COVID-19 surge.

Background: The evolution of antimicrobial resistance among critically ill patients before, during, and after the COVID-19 surge remains unclear.

Methods: We retrospectively analyzed critically ill mechanically ventilated adult patients admitted to 8 Brazilian hospitals from Jan 1, 2018 to Apr 30, 2023. We stratified the patients into 3 periods: pre-surge (Jan 01, 2018-Mar 01, 2020), surge (Mar 01, 2020-Oct 01, 2021), and post-surge (after October 01, 2021).

Segmentation of four-chamber view images in fetal ultrasound exams using a novel deep learning model ensemble method.

Fetal echocardiography, a specialized ultrasound application commonly utilized for fetal heart assessment, can greatly benefit from automated segmentation of anatomical structures, aiding operators in their evaluations. We introduce a novel approach that combines various deep learning models for segmenting key anatomical structures in 2D ultrasound images of the fetal heart. Our ensemble method combines the raw predictions from the selected models, obtaining the optimal set of segmentation components that closely approximate the distribution of the fetal heart, resulting in improved segmentation outcomes.

Mechanical Strain, Temperature, and Misalignment Effects on Data Communication between Piezoceramic Ultrasonic Transducers.

Acoustic waves can be used for wireless telemetry as an alternative to situations where electrical or optical penetrators are unsuitable. However, the response of the ultrasonic transducer can be greatly affected by temperature variations, mechanical deformations, misalignment between transducers, and multiple layers in the propagation zone. Therefore, this work sought to quantify such influences on communication between ultrasonic transducers.

Prediction of multidrug-resistant bacteria (MDR) hospital-acquired infection (HAI) and colonisation: A systematic review.

Background: Hospital-Acquired Infections (HAI) represent a public health priority in most countries worldwide. Our main objective was to systematically review the quality of the predictive modeling literature regarding multidrug-resistant gram-negative bacteria in Intensive Care Units (ICUs).

Methods: We conducted and reported a Systematic Literature Review according to the recommendations of the PRISMA statement.

From screens to seas: Tech contaminants in tiger sharks.

The potential negative impacts of Technology-Critical Elements (TCEs) on the environment and wildlife, despite increasingly recognized, remain largely overlooked. In this sense, this study aimed to investigate the concentrations of several TCEs, including rubidium (Rb), titanium (Ti) and various Rare Earth Elements (REEs), in different tissues of tiger sharks. Sharks incidentally caught by artisanal fleets in southern Brazil were opportunistically sampled and liver, gills, kidneys, heart, muscle, eyes, brain, skin, and teeth were analyzed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS).

Comparing causal random forest and linear regression to estimate the independent association of organisational factors with ICU efficiency.

Purpose: Parametric regression models have been the main statistical method for identifying average treatment effects. Causal machine learning models showed promising results in estimating heterogeneous treatment effects in causal inference. Here we aimed to compare the application of causal random forest (CRF) and linear regression modelling (LRM) to estimate the effects of organisational factors on ICU efficiency.

Application of the EBSD Technique in the Study of Porosity and Permeability in Deformation Bands in Sandstone.

Deformation bands are common constituents of porous clastic fluid reservoirs. Various techniques have been used to study deformation band structure and the associated changes in porosity and permeability. However, the use of electron backscatter diffraction technique is limited.

The place of health in the EU-CELAC interregional cooperation from 2005 to 2023: a historical, empirical and prospective analysis.

Background: Much has been said by actors from different fields and perspectives about the manifold changes in world affairs triggered by the COVID-19 pandemic. In this context, it is to be expected that there will be impacts on long-standing partnerships such as the one between the European Union and the Community of Latin American and Caribbean Countries. However, few studies have demonstrated these impacts, either empirically, by uncovering their specificities or from a historical perspective, to allow for a reasonable methodological comparison of the patterns used to define the partnership and that have changed or have been affected in some way by the pandemic.

Objective: To evaluate the histomorphometric and computerized microtomographic (Micro-CT) analysis of the regenerated bone tissue from maxillary sinus augmentation surgery, with and without using the collagen membrane on the external osteotomy window.

Materials And Methods: Twelve patients were selected for this prospective, controlled, and randomized study. The patients were submitted to bilateral maxillary sinus surgery in a split-mouth design.

Noisy kinetic-exchange opinion model with aging.

We study the critical behavior of a noisy kinetic opinion model subject to resilience to change depending on aging, defined as the number of interactions before a change of opinion state. In this model, the opinion of each agent can take three discrete values, the extreme ones ±1, and also the intermediate value 0, and it can evolve through kinetic exchange when interacting with another agent, or independently, by stochastic choice (noise). The probability of change by pairwise interactions depends on the age that the agent has remained in the same state, according to a given kernel.

Measurement Uncertainty and Risk of False Compliance Assessment Applied to Carbon Isotopic Analyses in Natural Gas Exploratory Evaluation.

The concept of uncertainty in an isotopic analysis is not uniform in the scientific community worldwide and can compromise the risk of false compliance assessment applied to carbon isotopic analyses in natural gas exploratory evaluation. In this work, we demonstrated a way to calculate one of the main sources of this uncertainty, which is underestimated in most studies focusing on gas analysis: the δC calculation itself is primarily based on the raw analytical data. The carbon isotopic composition of methane, ethane, propane, and CO was measured.
