On January 8th, 2023, a week after the democratically elected president Luiz Inacio Lula da Silva was confirmed, supporters of the former president Jair Bolsonaro outnumbered Brazil's security forces and invaded all three branches of government: Congress, the Supreme Court, and the governmental Palace in Brazil's capital, Brasilia. Rioters broke windows, vandalized offices, destroyed original paintings, and documented their actions through social media. 2 Reminiscent of January 6, 2021, this insurrection marks the greatest challenge to Brazil's democratic establishment since its transition to democracy in the late 1980s, after a decades-long military dictatorship. In a 2022 interview with Dr. Ramos, Head of Constitutional Law at Universidade de Sao Paulo, Georgetown Journal of Intenrational Affairs (GJIA) explores Brazil's dictatorial past and its implications for a January 6th-style insurrection. GJIA conducted a second interview with Dr. Ramos on February 10, 2023 (post-insurrection), exploring the impact on Brazil's political instability and providing recommendations for a stronger democratic government. Both interviews are included in this article. [ABSTRACT FROM AUTHOR]

Objective: To evaluate clinical outcomes and factors associated with mortality, focusing on secondary infections, in critically ill patients with COVID-19 in three Brazilian hospitals during the first pandemic wave. Methods: This was a retrospective observational study involving adult patients with COVID-19 admitted to one of the participating ICUs between March and August of 2020. We analyzed clinical features, comorbidities, source of SARS-CoV-2 infection, laboratory data, microbiology data, complications, and causes of death. We assessed factors associated with in-hospital mortality using logistic regression models. Results: We included 645 patients with a mean age of 61.4 years. Of those, 387 (60.0%) were male, 12.9% (83/643) had undergone solid organ transplant, and almost 10% (59/641) had nosocomial COVID-19 infection. During ICU stay, 359/644 patients (55.7%) required invasive mechanical ventilation, 225 (34.9%) needed renal replacement therapy, 337 (52.2%) received vasopressors, and 216 (33.5%) had hospitalacquired infections (HAIs), mainly caused by multidrug-resistant gram-negative bacteria. HAIs were independently associated with a higher risk of death. The major causes of death were refractory shock and multiple organ dysfunction syndrome but not ARDS, as previously reported in the literature. Conclusions: In this study, most of our cohort required invasive mechanical ventilation and almost one third had HAIs, which were independently associated with a higher risk of death. Other factors related to death were Charlson Comorbidity Index, SOFA score at admission, and clinical complications during ICU stay. Nosocomial COVID-19 infection was not associated with death. The main immediate causes of death were refractory shock and multiple organ dysfunction syndrome. [ABSTRACT FROM AUTHOR]

Neonatal screening is essential for child health and has the following purposes: (1) pulse oximetry screening to evaluate congenital heart diseases; (2) red reflex examination to investigate eye diseases; (3) newborn hearing screening test to evaluate congenital hearing diseases; (4) tongue test to evaluate the lingual frenulum and identify communication and feeding problems; (5) the Guthrie test to screen for metabolic diseases. This study investigated the prevalence of the five neonatal screening tests and its associated institutional and socio-cultural factors using a cross-sectional study with 415 mother and baby binomials from public maternity hospitals in Natal, RN, Brazil in 2019. Pearson's chi-squared, Mann-Whitney and Poisson regression tests were used, with a significance of p ≤ 0.05 and a 95% confidence interval. The sample loss was 71 mothers (17%). The prevalence in the first week and at the end of 28 days was 93% and 99.5% (pulse oximetry screening), 60% and 97.6% (red reflex examination), 71.9% and 93.6% (Guthrie test), 35.5% and 68.2% (hearing screening test), and 19% and 48.9% (tongue test). Only 152 newborns (36.6%) underwent all five tests. The performance of the tests was associated in the final model (p ≤ 0.05) with the residence of the mothers in the state capital (PR = 1.36; 95% CI = 1.18–1.56) and the provision of guidance for mothers about the five tests in maternity hospitals (PR = 1.30; 95% CI = 1.08–1.67). None of the tests met full coverage, and regional inequities were identified indicating the need to restructure the institutions, training and qualification procedures to improve of the work processes and longitudinal care.

Objectives: to analyze the variation in the incidence rates of congenital syphilis according to the spatial distribution of Life Condition Index (LCI) among neighborhoods in the city of Recife-PE. Methods: an ecological study, developed from 3,234 cases of congenital syphilis notified in the Sistema de Informação de Agravos de Notificação (Severe Disease Notification Information System), between 2007 and 2016. LCI was built from seven variables related to the dimensions of the environment, education and income, aggregated at the neighborhood levels and spatially distributed in four strata: very high, high, low and very low. The correlation between the rates of congenital syphilis in the strata and LCI was investigated by applying the Spearman correlation coefficient and demonstrated by means of scatter graphics. Results: the mean rate on disease incidence was 6.8 cases per thousand live births. There was a higher incidence in the strata of very low and low living conditions, as well as in Districts that presented poor sanitary conditions and low schooling for the head of the family (District VII), higher proportion of illiteracy among 10 and 14 year olds (District II) and low income of the head of the household (Districts I, II and VII). Conclusions: this study showed the persistence of health inequalities in areas with worse living conditions. [ABSTRACT FROM AUTHOR]

Objective: To conduct a national survey of intensive care professionals to identify the practices for promoting sleep in adult intensive care units in Brazil and describe the professionals' perceptions of the importance of sleep for patients. Methods: An electronic questionnaire was distributed by the clinical research cooperation network of the Associação de Medicina Intensiva Brasileira and by the Brazilian Research in Intensive Care Network to physicians and nurses registered with the association. The questionnaire evaluated the profile of the respondents, the profile of their intensive care units, whether protocols for promoting sleep were present, the pharmacological and nonpharmacological measures typically employed in the unit, and the professionals' perceptions regarding sleep in critically ill patients. Results: A total of 118 questionnaires were evaluated. The Southeast region of the country was the most represented (50 questionnaires, 42.4%). The majority of units had a clinical-surgical profile (93 questionnaires; 78.8%), and 26 had a continuous visitation policy (22.0%). Only 18 intensive care units (15.3%) reported having protocols for promoting sleep. The most cited measure for sleep promotion was reducing light during the night (95 questionnaires; 80.5%), which was more often performed in private intensive care units. Almost all of the responders (99%) believed that poor-quality sleep has a negative impact on patient recovery. Conclusion: The responses to this Brazilian survey revealed that few intensive care units had a program for promoting sleep, although almost all participants recognized the importance of sleep in patient recovery.

The present work aimed to analyze the simulations of surface fluxes of sensible and latent heat, and global radiation using the mesoscale atmospheric model (WRF) for the Bananal Island (Tocantins state, Brazil) region during three distinct seasonal periods (flooded, dry, and wet) in 2004. The final analysis of the NCEP global model was used as initial and boundary conditions of the WRF, which horizontal resolution (5 km) and physical parameterizations follow the operational settings used at CPTEC/INPE. The global radiation, the simulated sensible and latent heat fluxes were consistent with the observed data for the daily cycle, where the R² was higher than 0.8, showing a good correlation between the data. However, the WRF outputs overestimates/underestimates follow a distinct seasonal pattern between global radiation and heat fluxes. There are some hypotheses for this result, such as potential limitations of the model in describing the surface conditions, whether static or dynamic. Future studies may investigate how sensitive the WRF would be when updating surface conditions for scenarios closer to reality, especially the flooded surface situation. [ABSTRACT FROM AUTHOR]

• An alternative for sequestration of the CO 2 separated from the pre-salt oil and gas production in Brazil is presented. • The potential for CO 2 sequestration based on mineral carbonation in basaltic rocks of Campos Basin is discussed. • The Brazilian depleted volcanic reservoirs are adequate for the CO 2 mineralization method. • The potential for injection capacity in the volcanic reservoirs is good to excellent. • Location and geological aspects make the basaltic reservoirs a significant opportunity to reduce CO 2 emissions from the oil industry in Brazil. The pre-salt oil and gas production in Brazil faces a significant challenge due to the high CO 2 content in these reservoirs. Approximately 600,000 t of CO 2 are reinjected monthly in the reservoirs, but the increased production of CO 2 will demand alternatives for sequestration. Experiments and pilot projects have demonstrated the viability of CO 2 sequestration through the mineralization method in basaltic rocks. Here, we present a study aimed at demonstrating the feasibility of using the volcanic rocks of the Cabiúnas Formation, located at the base of the pre-salt section in shallow waters of the Campos Basin, for CCS projects. We used legacy data to determine the regional characteristics and porosity distribution of the volcanic sequence to assess the feasibility of geological sequestration in this region. Our estimates demonstrated that the Cabiúnas flood basalts have a good to excellent storage capacity. The modeling of a 31km2 hypothetical reservoir with a thickness of 300 m in the upper part of the sequence above the Badejo Field revealed a storage estimate of 16–47 Mt. The technical aspects discussed in this study provide valuable insights that can help with the development of future CCS projects in the volcanic rocks of this petroleum province.

The mental foramen (MF) is an important anatomic landmark of the mandible, through which the mental nerve and blood vessels emerge. The importance of MF in dental practice is especially related to dental implants placement and other surgical procedures in the region. It is fundamental to be careful in order to avoid nerve and vessels injury during procedures. Anatomic variations of the MF can be found, such as occurrence of multiple foramina and unusual location. In very rare occasions, the absence of MF can be detected. The observation of this variation is not always possible using only conventional radiographs. The modern imaging resource cone beam computed tomography (CBCT) allows an accurate three-dimensional assessment of MF, as well as the identification of its variations. The aim of this article is to report MF absence and hypoplasia detected in CBCT images of a 27-year-old daughter and her 63-year-old mother, both from Brazil. Despite the MF anatomic variations, they presented no sensorial disturbance in the regions supplied by the mental nerve. [ABSTRACT FROM AUTHOR]

Objective: The aim of the study is to verify the effects of a 3-mo dual-task training on motor and cognitive functions in community-dwelling older adults. Design: In this prospective, single-blinded, controlled clinical trial, a total of 40 participants were allocated to either the experimental or the control (no-exercise) group. The intervention program consisted of a combination of motor and cognitive exercises conducted twice a week on nonconsecutive days. The main outcome measures were postural stability, mobility, fear of falling, and cognitive functions. Multiple analyses of variancewere used to assess the impact of the dual-task training. Effect sizes (η²p) were reported. Significance was set at 5%. Results: Compared with the control group, participants who underwent the dual-task training showed positive outcomes in terms of postural stability (η²p = 0.298, P = 0.020), mobility (η²p = 0.285, P = 0.003), and cognitive functions (η²p = 0.536, P = 0.001). No significant differences were observed between the groups in terms of the fear of falling (P = 0.566). Conclusions: Three-month dual-task training was beneficial for postural control, mobility, and cognitive functions in community-dwelling older adults. Based on the present findings, healthcare professionals should consider incorporating dual-task training into clinical practice. [ABSTRACT FROM AUTHOR]

The Fátima Basin is a small Cretaceous interior basin that was formed within the continental Borborema Province in northeastern Brazil. Its formation was related to the opening of the southern Atlantic Ocean. This study investigates the hypothesis of post-rift tectonic reactivation within this basin through an integrated set of geophysical (aeromagnetic), surface (outcrops), and subsurface (boreholes) data to model the tectono-stratigraphic framework of the basin. An analysis of several morphometric parameters, including the slope index, relief aspect, stream profiles, asymmetry factor (AF), stream-gradient index (SL), and valley floor width-to-height ratio (VF) was used to identify possible tectonic adjustments related to post-rift stress fields. The integration of geophysical and subsurface data showed that the basin possesses a half-graben geometry with the main basin axis trending NE-SW. Two families of topographic lineaments were identified: 1) NE-SW, corresponding to the main shear zones and faults of the Pre-Cambrian basement, and 2) NW-SE, representing faults and fractures in the adjacent basement and the sedimentary cover. A digital elevation model revealed that the maximum topographic elevation was 950 m, associated with deposits of the Paleozoic Tacaratu Formation located over the hinge line of the flexural margin of the basin. The AF values in the basin ranged between 25 and 76, and first- and second-order SL index anomalies were frequent, especially in the faulted border, the southeast sector, and the northeast sector. Analyses of the main river channels revealed VF values of around 1, which indicate active incisions in the river valleys. We suggest that the basin was subjected to differential uplift during the Cenozoic, which strongly affected the southeast and northeast sectors. Based on the exhumation of the Tacaratu Formation deposits, we estimate that the basin experienced approximately 500 m of uplift that influenced the erosion of Cretaceous deposits and adjacent basement rocks. • Cretaceous Interior Basin. • Morphometric Parameters. • Drainage Network. • Borborema Cenozoic Uplift.

Abstract: Asphaltene and resins are heavy fractions of petroleum responsible for serious problems during petroleum production. These problems include the formation of organic deposits in oil reservoirs; wells, transport pipelines and equipment, and can significantly increase the production operational costs. The nature and behavior of asphaltene in crude oils is complex and changes in temperature, pressure and composition of crude oils during production can result in precipitation of asphaltene components. Potential solutions for these problems include physical removal of deposits, solvent washes and treatment with dispersant agents. The use of soluble amphiphile oils provides the most practical and economical solution for deposits treatment. In this work, the inhibitory capacity of a number of new chemical additives to asphaltene precipitation was examined in three types of Brazilian crude oils. Low molar mass ethoxylated nonylphenols, vegetable oils (coconut essential oil, sweet almond, andiroba and sandalwood oil) and organic acids (linoleic, caprylic and palmytic) displayed highest capacity to inhibit asphaltene deposition. The dissolution capacity of some additives was evaluated for two asphaltenic deposits in aliphatic solvents. The remarkable solubilization effect displayed by dodecylbenzenesulfonic acid, confirmed the importance of acid–base interactions in this process. The results also revealed distinct mechanisms for asphaltene solubilization/dispersion in aliphatic solvents and inhibition of asphaltene precipitation in crude oils. [Copyright &y& Elsevier]

The structural characterization of fractures is crucial to understand the processes of fluid flow in tight reservoirs. This contribution focuses on the role played by vertical fractures on the permo-porosity properties of the Aptian tight carbonate sequence of the Crato Formation, Araripe Basin (NE Brazil). The study performed a structural analysis in two different scales: reservoir scale (approximately 19.000 m2) and outcrop scale (approximately 125 m2), focusing on the fracture networks in lacustrine laminates, which have been investigated as an analogue of carbonate facies observed within the pre-salt reservoir sequence of the marginal basins in Brazil. This study employed a combination of systematic outcrop-based fracture characterization involving digital outcrop models and mechanical stratigraphy analysis. To evaluate the influence of vertical fracture systems in the fracture porosity and the equivalent permeability we performed DFN (Discrete Fracture Network) models. We focused on vertical calcite-filled fractures, oriented in two principal directions: set 1 NNW-SSE and set 2 NE-SW. Each set shows different vertical linkage patterns due to the influence of the mechanical intervals. Results of the outcrop scale model show similar behaviour for both fracture porosity and equivalent permeability, indicating that storage capacity and fluid flow may not be affected by vertical linkage of fractures. The reservoir scale DFN models show that the fracture porosity was greater in models which consider through-going continuous fractures than in models that consider the segmentation (discontinuity) of vertical fractures. Considering the vertical connectivity of fractures, the equivalent horizontal permeability (Kxx and Kyy) showed similar values in both scale models. This implies that vertical segmentation of fractures does not impact fluid flow in horizontal directions. The calculated values of equivalent vertical fracture permeability (Kzz) at reservoir scale are one order of magnitude higher in the DFNs that consider continuous fractures. Our results suggested that vertically continuous fractures enhance preferential flow pathways allowing greater vertical fluid flow than segmented fracture networks in tight carbonate reservoirs. • Aptian Crato Formation reveals that bed-normal continuous fractures enhance fluid flow in tight carbonate reservoir analogue. • Discrete Fracture Network models expose how bed-normal fractures impact porosity and permeability at different scales. • Outcrop pseudo-wells offer insights into fracture-mechanical relationships, guiding understanding of vertical fracture linkage. • Excellent Pre-Salt reservoir analogue in the Crato Formation.

This study characterizes the existence of Quaternary sediments in the Transversal Zone of the Borborema Province (Northeastern Brazil). The sediments comprise paleosoils, unconsolidated sands and gravel deposits, which overlie Precambrian basement rocks. The new data on these deposits includes sedimentological and stratigraphic aspects, and age definition through quartz optically stimulated luminescence (OSL) method. The outcrops were subdivided in two broad groups (named RL and Rca) referring to nearby towns where the samples were collected. OSL ages from the RL group provided ages between ca. 160.15 ± 38.26ka to 4.30 ± 2.18ka, whereas the sediments in the Rca group present OSL ages from 67.45 ± 18.24ka to 7.67 ± 2.74ka. The geochronological results reveal that these sediments were deposited during a time period from the Pleistocene to the Holocene. Deposits are chronocorrelated to Post-Barreiras (ca. 74-2ka in age), apart from the Barreiras Formation (ca. 25 to 17Ma in age), by an expressive hiatus in the Northeast Brazil. Our investigation suggest that the sediments, in the study area, are a reworking of crystalline basement and differs genetically from Post-Barreiras in the coastal zone, which are reworked from the Barreiras Formation. The combination of intense humid chemical weathering during the Pleistocene-Holocene influenced the quaternary deposition in the study area. In addition, the regional brittle tectonic reactivation of shear zones also during the Paleogene influenced the space of accommodation that allowed the deposition of these sediments. • Exposed sediments overlying the Precambrian basement of Borborema Province are identified. • Quartz OSL geochronology reveals a Pleistocene-Holocene depositional age. • The sediments were deposited by influence of Cenozoic uplift in the northeastern Brazil. • Intense chemical weathering influences the deposition.

This research aimed to characterize, evaluate and compare the spatial distribution of the leading bed variables, animal welfare indicators, and milk production in a closed compost-bedded pack barn (CBP) with a negative tunnel ventilation system, for summer and winter periods. The study was carried out in a CBP located in the Zona da Mata region, Minas Gerais, Brazil. The geostatistical modeling technique evaluated the variables of temperature, moisture content, and pH (on the surface and depth of 0.20m) across the length of the bed. Bed samples were characterized for carbon (C), nitrogen (N), and C:N ratio. Cows housed in the CBP were assessed for locomotion and hygiene scores and average milk production. To evaluate the thermoregulation of the cows, the respiratory rate (RR) and surface temperature (ST) were measured. Geostatistical analysis showed spatial dependence and the non-uniformity of the spatial distribution of bed variables. The worst levels of bed temperature and moisture were found in the regions close to the evaporative cooling plate, surrounding the feeding alley, and in the region with the highest cow stocking. The C:N ratio, obtained in both climatic seasons of the year, remained outside the recommended range for ideal composting. During the summer and winter, the bed variables' values suggest that the material was below levels for optimal composting; however, the aerated inner layer was biologically active. The high animal density significantly impacted the worsening of the bed moisture content and internal temperature. In general, dairy cows showed adequate hygiene (score of 1 and 2) and locomotion (score of 0 and 1) scores for the two climatic seasons evaluated, indicating good welfare conditions. In relation to RR and ST, the summer period presented less favorable environmental conditions. During winter, the average milk production was 28.1 ± 7.2 kg day-1, and during summer, it was 26.9 ± 6.7 kg day-1. • The use of geostatistics made possible to assess the quality of the CBP bed. • The high cow stocking density had an impact on the worsening of the moisture content and internal temperature in the bed. • Dairy cows showed a good hygiene and locomotion scores in the CBP. • In the closed CBP system average milk production was slightly lower during the summer in comparison with winter. • The use of infrared thermography made possible to evaluate the surface temperatures of in cows and bed in closed CBP.

Toxoplasmosis is a disease caused by T. gondii , a protozoa which affects humans and animals and is widely distributed worldwide. In humans, there is great concern due to the serious consequences that can occur in the infection of pregnant women and the newborn. The early diagnosis of gestational toxoplasmosis is important for treatment to be carried out in order to prevent vertical transmission or reduce damage. The diagnosis can be made through the detection of antibodies in pregnant women or neonates and PCR of amniotic fluid. Previous studies have also reported PCR of the placenta as a good diagnostic test. Our study evaluated the detection of T. gondii DNA in placenta samples from parturients seen at the University Hospital of Santa Maria, Southern Brazil and treated during the pregnancy. We performed PCR in forty samples and five were positive, representing 12.5%. When correlating the treatment time and the detection of DNA in the placentas, no significant result was found. The prevalence of positive samples was lower than in other studies in the literature. The data reaffirm the importance of carrying out the analysis of the placenta. • Toxoplasma gondii DNA detection in pregnant women treatment. • Treatment time and detection of T. gondii DNA in pregnant women. • Congenital Toxoplasmosis monitoring in a T. gondii outbreak.
