Postoperative cognitive dysfunction (POCD), a complication following procedures such as orthopedic surgery, is associated with a worsened prognosis, especially in the elderly population. Several mechanisms have been proposed for communication between the immune system and the brain after surgery. In an experimental tibial fracture (TF) model, we aimed to understand the role of the NLR family pyrin domain containing 3 (NLRP3) on oxidative stress and mitochondrial dysfunction as mechanisms underlying POCD in aged and adult rats.

Developmental plasticity refers to conditions and circumstances that increase phenotypic variability. In infancy, plasticity expands and contracts depending on domains of functioning, developmental history, and timing. In terms of language processing, infants attend to and discriminate both native and non-native phonetic contrasts, but selectively attune to their native phonemes by the end of the first postnatal year.

Background: Concerns about COVID-19-associated coagulopathy (CAC) in pregnant individuals were raised in early pandemic.

Methods: An ISTH-sponsored COVID-19 coagulopathy in pregnancy (COV-PREG-COAG) international registry was developed to describe incidence of coagulopathy, VTE, and anticoagulation in this group.

Results: All pregnant patients with COVID-19 from participating centers were entered, providing 430 pregnancies for the first pandemic wave.

Background: Using the reaction history in logistic regression and machine learning (ML) models to predict penicillin allergy has been reported based on non-US data.

Objective: We developed ML positive penicillin allergy testing prediction models from multisite US data.

Methods: Retrospective data from 4 US-based hospitals were grouped into 4 datasets: enriched training (1:3 case-control matched cohort), enriched testing, nonenriched internal testing, and nonenriched external testing.

Article Synopsis
  • The study aimed to find the optimal method for creating an effective adsorbent from volcanic rock powder waste through alkaline fusion under various conditions.
  • Nine samples were produced by adjusting temperature and the ratio of NaOH to volcanic rock, which were then tested for their ability to adsorb certain dyes and metal ions.
  • The results showed that a temperature of 550 °C and a NaOH/volcanic rock ratio of 1 maximized the adsorbent’s capacity to remove contaminants, achieving high adsorption rates for dyes and metals.

Traffic simulations are valuable tools for urban mobility planning and operation, particularly in large cities. Simulation-based microscopic models have enabled traffic engineers to understand local transit and transport behaviors more deeply and manage urban mobility. However, for the simulations to be effective, the transport network and user behavior parameters must be calibrated to mirror real scenarios.

Objective: The aim of this study was to investigate the frequency of breakfast consumption and estimate its associations with the consumption of food at different degrees of industrial processing and with overweight indicators in Brazilian adolescents.

Methods: This cross-sectional study involved a probabilistic sample of 14- to 19-y-old adolescents enrolled in 29 public schools in the municipality of Juiz de Fora, MG, Southeast Brazil (n = 805). The frequency of breakfast consumption was evaluated via a questionnaire (classified into "do not consume", "sometimes consume", and "regularly consume").

Article Synopsis
  • The study created two new functionalized carbon nanotube materials (MWCNT-OH and MWCNT-COOH) infused with magnetite, using a specific method to ensure effective nanoparticle distribution.
  • Characterization techniques showed that the -OH groups on MWCNTs enhance the interaction with magnetite, and tests demonstrated that MWCNT-OH-Mag had superior adsorption capacity for pollutants like 2,4-D and Atrazine, particularly at different pH levels.
  • Results indicate that these new materials are promising for water purification, maintaining stability in solutions and showing effective pollutant removal in wastewater experiments.

Objective: The aim of this study was to investigate the involvement of Brazilian adolescents in home cooking, estimating its associations with sex and socioeconomic status.

Methods: This cross-sectional study involved a probabilistic sample of 14- to 19-y-olds enrolled in 29 public schools in the municipality of Juiz de Fora, MG, Southeast Brazil (n = 835). To assess involvement in home cooking, a 12-question questionnaire was used.

The Calophyllum inophyllum species annually produces a large volume of cylindrical fruits, which accumulate on the soil because they do not have nutritional value. This study sought to enable the use of this biomass by producing activated biochar with zinc chloride as an activating agent for further application as an adsorbent in batch and fixed bed columns. Different methodologies were used to characterize the precursor and the pyrolyzed material.

Brazil's production and consumption of açai pulp (Euterpe oleracea) occur on a large scale. Most of the fruit is formed by the pit, which generates countless tons of residual biomass. A new purpose for this biomass, making its consumption highly sustainable, was presented in this study, where activated carbon (AC) was produced with zinc chloride for later use as an adsorbent.

In this study, the residual pods of the forest species Erythrina speciosa were carbonized with ZnCl to obtain porous activated carbon and investigated for the adsorptive removal of the drug paracetamol (PCM) from water. The PCM adsorption onto activated carbon is favored at acidic solution pH. The isothermal studies confirmed that increasing the temperature from 298 to 328 K decreased the adsorption capacity from 65 mg g to 50.

The study analyzed the potential of leaf powder prepared from the residual leaves of the species Sansevieria trifasciata, as a potential adsorbent for methylene blue (MB) removal. The equilibrium was reached fast for almost all concentrations after 60 min, obtaining the maximum capacity of 139.98 mg g for 200 mg L.

Angiotensin (Ang) II, the main active member of the renin angiotensin system (RAS), is essential for the maintenance of cardiovascular homeostasis. However, hyperactivation of the RAS causes fibrotic diseases. Ang II has pro-inflammatory actions, and moreover activates interstitial fibroblasts and/or dysregulates extracellular matrix degradation.

Geopolymers were obtained from ashes through an alternative geopolymerization process and applied to remove Ni, Cu, Co, and Ag from synthetic aqueous media and real effluents. The study in synthetic solutions revealed that pseudo-second-order and general order models were the best to fit the kinetic curves. To represent the equilibrium curves, Langmuir and Freundlich were the most adequate.
