„Cień Kaina”. Temat wojny w wypowiedziach papieża Franciszka
Authors: Okupnik Małgorzata
Published: February 2023

Christians feel that they should not be indifferent to war, and that it is their duty to react to harm, particularly done to civilians. Catholics expect their greatest authority, the Pope, to have a firm say about war and peace. May people, however, have had the impression that Pope Francis is erratic and assesses the situation in a wrong way. Although he follows the beaten track paved by the Church’s social science and Vatican diplomacy, some of his statements (and things left unsaid) caused and still are causing controversy. The article attempts at understanding the position of Pope Francis. It analyses his utterances regarding war, taken from sources such as the book titled Against War, speeches and social media (Twitter).
Problem psychomanipulacji religijnej w kontekście globalnej pentekostalizacji chrześcijaństwa
Authors: Kobyliński Andrzej
Published: February 2023

This article focuses primarily on a synthetic presentation of the global process of pentecostalization as well as the analysis of the selected religious abuses that occur in Christian communities on the grounds of emotional and syncretic Pentecostal religiosity. Over the last two decades, the interest in the problem of psychomanipulation and religious abuses has grown significantly in the Catholic Church and in other Christian denominations. This phenomenon is subject to in-depth philosophical, psychological, sociological, theological and cultural analyses, particularly in countries such as the United States, France or Great Britain. Religious abuse, also known as spiritual abuse or spiritual violence, refers to various forms of psychomanipulation, power, and control over people through religion, faith, or beliefs. The risk of abuse is especially high in the context of contemporary syncretic Neo-Pentecostal religiosity which is characterized by the so-called praying in tongues, miracles, emphasizing the presence of the devil in the world, exorcisms, prayers of deliverance, healings, introducing participants of prayer meetings into altered states of consciousness, etc. In the application of such methods, the principle of informed consent, which in medical practice applies to the relationship between doctors and patients, should be one of the basic ethical norms implemented with the aim of protecting against religious abuse and regulating the relationship of leaders to members of their communities.
Mandibular advancement reduces pharyngeal collapsibility by enlarging the airway rather than affecting velopharyngeal compliance

Mandibular advancement devices (MADs) are frequently prescribed for obstructive sleep apnea (OSA) patients, but approximately one third of patients experience no therapeutic benefit. Understanding the mechanisms by which MADs prevent pharyngeal collapse may help optimize MAD therapy. This study quantified the relative contributions of changes in airspace cross‐sectional area (CSA) versus changes in velopharyngeal compliance in determining MAD efficacy. Sixteen patients with moderate to severe OSA (mean apnea–hypopnea index of 32 ± 15 events/h) underwent measurements of the velopharyngeal closing pressure (PCLOSE) during drug induced sedated endoscopy (DISE) via stepwise reductions in nasal mask pressure and recording of the intraluminal pressure with a catheter. Airspace CSA was estimated from video endoscopy. Pharyngeal compliance was defined as the slope of the area–pressure relationship of the velopharyngeal airspace. MAD therapy reduced PCLOSE from a median of 0.5 cmH2O pre‐advancement to a median of −2.6 cmH2O post‐advancement (p = 0.0009), increased the minimal CSA at the velopharynx by approximately 20 mm2 (p = 0.0067), but did not have a statistically significant effect on velopharyngeal compliance (p = 0.23). PCLOSE had a strong correlation with CSA but did not correlate with velopharyngeal compliance. Our results suggest that MADs reduce velopharyngeal collapsibility by increasing airway size as opposed to affecting velopharyngeal compliance. This contradicts the speculation of previous literature that the effectiveness of MADs is partially due to a reduction in velopharyngeal compliance resulting from stretching of the soft palate. These findings suggest that quantification of velopharyngeal CSA pre‐ and post‐MAD advancement has potential as a biomarker to predict the success of MAD therapy.

Published: February 2023

Mitochondrial calcium (mCa2+) uptake occurs via the Mitochondrial Ca2+ Uniporter (MCU) complex and plays a critical role in mitochondrial dynamics, mitophagy, and apoptosis. MCU complex activity is in part modulated by the expression of its regulatory subunits. Cardiovascular disease models demonstrated altered gene/protein expression of one or multiple subunits in different cells, including vascular endothelial cells (ECs). MCU complex activity was found necessary for stable flow (s‐flow)‐induced mitophagy and promotion of an atheroprotective EC phenotype. Disturbed flow (d‐flow) is known to lead to an atheroprone phenotype. Despite the role of MCU in flow‐regulated EC function, flow‐induced alterations in MCU complex subunit expression are currently unknown. We exposed cultured human ECs to atheroprotective (steady shear stress, SS) or atheroprone flow (oscillatory shear stress, OS) and measured mRNA and protein levels of the MCU complex members. SS and OS differentially modulated subunit expression at gene/protein levels. Protein expression changes of the core MCU, mCa2+ uptake 1 (MICU1) and MCU regulator 1 (MCUR1) subunits in SS‐ and OS‐exposed, compared to static, ECs suggested an enhanced mCa2+ influx under each flow and a potential contribution to EC dysfunction under OS. In silico analysis of a single‐cell RNA‐sequencing dataset was employed to extract transcript values of MCU subunits in mouse carotid ECs from regions exposed to s‐flow or d‐flow. Mcu and Mcur1 genes showed significant differences in expression after prolonged exposure to each flow. The differential expression of MCU complex subunits indicated a tight regulation of the complex activity under physiological and pathological hemodynamic conditions.
Acclimatizing and training freely viewing marmosets for behavioral and electrophysiological experiments in oculomotor tasks
Authors: Saghravanian Seyed Javad , Asadollahi Ali
Published: February 2023

The marmoset is a small‐bodied primate with behavioral capacities and brain structures comparable to macaque monkeys and humans. Its amenability to modern biotechnological techniques like optogenetics, chemogenetics, and generation of transgenic primates have attracted neuroscientists' attention to use it as a model in neuroscience. In the past decade, several laboratories have been developing and refining tools and techniques for performing behavioral and electrophysiological experiments in this new model. In this regard, we developed a protocol to acclimate the marmoset to sit calmly in a primate chair; a method to calibrate the eye‐tracking system while marmosets were freely viewing the screen; and a procedure to map motor field of neurons in the SC in freely viewing marmosets. Using a squeeze‐walled transfer box, the animals were acclimatized, and chair trained in less than 4 weeks, much shorter than what other studies reported. Using salient stimuli allowed quick and accurate calibration of the eye‐tracking system in untrained freely viewing marmosets. Applying reverse correlation to spiking activity and saccadic eye movements, we were able to map motor field of SC neurons in freely viewing marmosets. These refinements shortened the acclimation period, most likely reduced stress to the subjects, and allowed more efficient eye calibration and motor field mapping in freely viewing marmosets. With a penetration angle of 38 degrees, all 16 channels of the electrode array, that is, all recorded neurons across SC layers, had overlapping visual receptive and motor fields, indicating perpendicular penetration to the SC.
I ain’t your f*cking Model Minority! Indexical orders of ‘Asianness’, class, and heteronormative masculinity
Authors: Chun Christian W.
Published: February 2023

By inscribing and ascribing particular indexical signifiers to people while ignoring and/or dismissing actual individual performative enactments and self-identifications, neoliberal multicultural discourses, in claiming tolerance and acceptance, frame racialized people as “an essentialized and totalized unit that is perceived to have little or no internal variation” (Ladson-Billings, Gloria. 2000. Racialized discourses and ethnic epistemologies. In Norman K. Denzin & Yvonna S. Lincoln (eds.), Handbook of qualitative research, 2nd edn., 257–277. Thousand Oaks, CA: Sage). In doing so, these discourses supposedly celebrating ‘diversity’ disregard the complexities, hybridities, and differences that constitute and are constitutive of any individual. Thus, in drawing on the ethos of tolerance and acceptance, ‘multicultural’ discourses paper over societal conflicts, internal divisions and oppressions, and homogenize racial, linguistic, and cultural identities ignoring the complex identifications people may perform and hold in any given interactional situational context. In this critical autoethnography, I illustrate how an indexical order of ‘Asianness’ in its ‘model minority’ variety has been shaped and subverted at times by my situated appropriations of various enregisterments (Agha, Asif. 2007. Language and social relations. Cambridge University Press) of a working-class heteronormative masculinity in interactional contexts. These enactments illuminate how an indexical order of an Asian American male has continually shifted and reacted to such positionings in a white supremacy society.
Life and work between home and “homeland”: a narrative inquiry of transnational Chinese adoptees’ identity negotiations across time and space
Authors: Lin Shumin , Wu Ming-Hsuan , Leung Genevieve
Published: February 2023

Unlike Korean or Vietnamese adoptees who came to the U.S. during the postwar era, Chinese adoptees are mostly abandoned female infants under China’s one-child policy from 1980 through 2015. Little work has documented Chinese adoptees’ identity (trans)formation across time and space. This study examines how three Chinese adoptees from the U.S. who chose to go to Taiwan to teach English make sense of their Chinese heritages and their lives in and out of Asia. Drawing on the frameworks of positioning and chronotopic identities, this cross-sectional, multiple case study documents the participants’ identity (trans)formations through their narratives on their moves across the U.S., China, and Taiwan during different points of their lives. Our adoptee participants’ home and work experiences over time represent diverse pathways for their negotiations of various aspects of their identities – linguistic, cultural, Chinese, American, Asian American, and adoptee – in their life trajectories transnationally. Their diverse experiences complicate current understandings of adoptee identities within and across the adoptive home, the “homeland” of their birth places, and beyond.
Optimization of lead-free CsSnI3-based perovskite solar cell structure
Authors: Arbouz Hayat
Published: February 2023

Perovskites are considered the most promising material for the latest generation of solar cells. However, due to the presence of lead in their composition, the development of non-toxic Perovskite cells has become an essential goal to enable their large-scale production. In this work, we have simulated, modeled and optimized the structure of a single solar cell that consists of a non-toxic cesium–tin–iodine CsSnI3 Perovskite absorber with a low band gap energy value of 1.3 eV, between TiO2 and PTAA materials as ETL and HTL layers, respectively. A simulation model describing the charge carrier processes and the effect of interface defect density is presented. Several structures based on alternative ETL and HTL materials are proposed. An optimal device structure is proposed based on the results obtained. An efficiency of 19.92% is obtained with V
oc = 0.829 V, J
sc = 30.68 mA/cm2 and FF = 73.33% using SnO2 and Spiro-OMeTAD as ETL and HTL materials. However, 29.22% is achieved using the optimal structure as the bottom cell in a tandem configuration.
Single-cell transcription analysis reveals the tumor origin and heterogeneity of human bilateral renal clear cell carcinoma
Authors: Wan Zhengqiang , Wang Yinglei , Li Aiqun , Li Cheng , Zheng Dongbing
Published: February 2023

Bilateral renal clear cell carcinoma (BRCC) is a rare type of renal cell carcinoma (RCC) that accounts for only 1–5% of RCC cases and has a poor clinical prognosis. The origin, tumor microenvironment, cellular molecular features, and intra-tumoral heterogeneity of BRCC are still unclear. We downloaded BRCC single-cell transcriptome sequencing data from the gene expression omnibus database biochip GSE171306, containing 3,575 cells from left-sided clear cell renal cell carcinoma (ccRCC) and 3,568 cells from right-sided ccRCC, and used a series of R packages for data quality control (QC) and subsequent analysis of BRCC single-cell transcriptome data, including the use of the R packages Seurat and scCancer for cell QC, identification of major cell types, and cell annotation; R package scran for calculation of cell cycle scores; R package infercnv for malignancy scoring of tumor cells; R package ReactomeGSA for functional enrichment analysis; R package Monocle 2 for the analysis of cell differentiation trajectories; and R package CellphoneDB for the analysis of intercellular interactions. In this study, by analyzing the high-quality single-cell transcriptome data of BRCC, we identified 18 cell types and found that left- and right-sided ccRCC were approximately the same in terms of cell type and the number of each cell but differed significantly in terms of tumor cell malignancy score, tumor microenvironment, and cell stemness score. In the cell differentiation trajectory analysis of BRCC, we found that endothelial cells and macrophages play an extremely important role in its tumor progression. Further cell communication analysis was performed, and we found that it may signal through ligand–receptors, such as vascular endothelial growth factor–vascular endothelial growth factor receptor1 (VEGF–VEGFR1), MIF–(CD74-CXCR4), and growth arrest-specific protein 6–AXL, to influence the development of BRCC. The analysis of single-cell transcriptomic data of human BRCC suggests that left- and right-sided ccRCC may be of the same tumor origin, but the left-sided ccRCC is more malignant and has a better immune response.

Authors: Basmacı Gültekin
Published: February 2023

In this study, the effects of cutting speed, tool geometry, and machining parameters on surface roughness and cutting forces in the turning of Nilo 36 superalloy have been investigated. An experimental design of the turning process was made with the Taguchi technique. In this way, optimum values were estimated with a small number of experiments. The grey correlation analysis method was used to determine the best parameter levels and plausible factors. While the most ideal value for the cutter with traditional geometry was achieved with experiment number 3, indicated by the GRA (grey relationship analysis) Rank value no. 1, the worst result was obtained with experiment number 9, and while the most ideal value for the cutter with wiper geometry was achieved with experiment number 2, indicated by the GRA Rank value no. 1, the worst result was obtained with experiment number 6. Results showed that experiments made by GRA-based parameters give better results on surface roughness and cutting forces.

Published: February 2023

This article presents the performance of cable-stayed bridge by representing a model using the ANSYS program under the influence of a concentrated load and then comparing them with the experimental results. One model was used in the analytical, and one was (harp type 1) used in the length of the girder (4,500 mm), height of the pylon (1,480 mm), and depth of the flange for the girder (40 mm). If cable-stayed bridges are constructed using the balanced cantilever method, the stability problem of the girder is more significant during the construction stage than at the initial state. In this study, to investigate the ultimate behavior of cable-stayed bridges, experimental and analytical studies were conducted for one model: Harp type 1. At the limit state, several plastic hinges occurred and the girders buckle along the entire span. Numerical analysis was conducted for the experimental model, and the results of which showed good agreement with the experimental results. The influence of such kind of effects on the analysis and the structural behavior of cable-stayed bridges has been examined in detail in the study. The dimensions of the model were also compared with institute civil engineering Code in terms of the height of the tower to the main space, and Back Span to the main span ratio. It was close to standard specifications. A finite element procedure for the nonlinear analysis of cable-stayed bridges is first set up, and then, a detailed static deflection analysis of such bridges is carried out.

Published: February 2023

In recent years, environmental issues have gradually become one of the most concerning issues in the world. New energy vehicles have attracted wide attention by their good environmental and social benefits such as zero exhaust emissions and low noise pollution. This paper proposes a regional charging demand forecasting method for electric vehicles (EVs) based on hierarchical charging decision model to solve the problem of charging pile capacity planning, which affects the charging decision behavior of EVs users. The Monte Carlo sampling model is adopted to obtain the time distribution of electric vehicle arriving at each functional area, the distribution of battery state of charge when arriving, and the distribution of average daily mileage. The negative exponential distribution model is used to obtain the average mileage distribution. The fuzzy system theory is proposed to calculate the charging probability, and the fuzzy rule base is adjusted according to the actual data to ensure that the fuzzy rule base is real and effective. Finally, the charging demand distribution curve of electric vehicles in each functional area is obtained by sampling simulation. Through experimental analysis, optimizing the capacity configuration of charging facilities in the station can well describe how electric vehicle users make charging decisions in the actual situation. The research on electric vehicle charging stations can slow down the waiting time of electric vehicle charging, and then affect the process of replacing fuel vehicles with electric vehicles to achieve the development goal of popularizing electric vehicles. It is of great significance for the promotion of new energy vehicles to rationally plan the location and capacity of electric vehicle charging stations.

Published: February 2023

Two-dimensional transition metal dichalcogenides (2D TMDs) have been demonstrated as one of the most outstanding materials not only for fundamental science but also for a wide range of photonic applications. However, an efficient way to control their excitonic properties is still needed for advanced applications with superior device performance. Here, we show that the exciton lifetime of WSe2 monolayer can be prolonged using metamaterials. We observe a ∼100% reduction in the electron-hole recombination rate of WSe2 monolayer placed on a hyperbolic metamaterial substrate and demonstrate that such a remarkable change results from the destructive image dipole interaction with the in-plane exciton transition dipole. Furthermore, this substantial increase in exciton lifetime leads to order-of-magnitude (10-fold) enhancement of photocurrent in the 2D WSe2-based hybrid photodetector with metamaterials. Tailoring the optical transition properties of 2D TMD materials with specially designed metamaterials, demonstrated here, will pave the way for developing 2D material-based optoelectronics.

Published: February 2023

Hyperactivation of the mechanistic target of rapamycin (mTOR) signaling pathway is linked to more than a dozen neurologic diseases, causing a range of pathologies, including excess neuronal growth, disrupted neuronal migration, cortical dysplasia, epilepsy and autism. The mTOR pathway also regulates angiogenesis. For the present study, therefore, we queried whether loss ofPtenorTsc2, both mTOR negative regulators, alters brain vasculature in three mouse models: one withPtenloss restricted to hippocampal dentate granule cells [DGC-Ptenknock-outs (KOs)], a second with widespreadPtenloss from excitatory forebrain neurons (FB-PtenKOs) and a third with focal loss ofTsc2from cortical excitatory neurons (f-Tsc2KOs). Total hippocampal vessel length and volume per dentate gyrus were dramatically increased in DGC-Ptenknock-outs. DGC-Ptenknock-outs had larger dentate gyri overall, however, and when normalized to these larger structures, vessel density was preserved. In addition, tests of blood-brain barrier integrity did not reveal increased permeability. FB-PtenKOs recapitulated the findings in the more restricted DGC-PtenKOs, with increased vessel area, but preserved vessel density. FB-PtenKOs did, however, exhibit elevated levels of the angiogenic factor VegfA. In contrast to findings withPten, focal loss ofTsc2from cortical excitatory neurons produced a localized increase in vessel density. Together, these studies demonstrate that hypervascularization is not a consistent feature of mTOR hyperactivation models and suggest that loss of different mTOR pathway regulatory genes exert distinct effects on angiogenesis.
Model-Based Approach Shows ON Pathway Afferents Elicit a Transient Decrease of V1 Responses
Authors: St-Amand David , Baker Curtis L.
Published: February 2023

Neurons in the primary visual cortex (V1) receive excitation and inhibition from distinct parallel pathways processing lightness (ON) and darkness (OFF). V1 neurons overall respond more strongly to dark than light stimuli, consistent with a preponderance of darker regions in natural images, as well as human psychophysics. However, it has been unclear whether this “dark-dominance” is because of more excitation from the OFF pathway or more inhibition from the ON pathway. To understand the mechanisms behind dark-dominance, we record electrophysiological responses of individual simple-type V1 neurons to natural image stimuli and then train biologically inspired convolutional neural networks to predict the neurons' responses. Analyzing a sample of 71 neurons (in anesthetized, paralyzed cats of either sex) has revealed their responses to be more driven by dark than light stimuli, consistent with previous investigations. We show that this asymmetry is predominantly because of slower inhibition to dark stimuli rather than to stronger excitation from the thalamocortical OFF pathway. Consistent with dark-dominant neurons having faster responses than light-dominant neurons, we find dark-dominance to solely occur in the early latencies of neurons' responses. Neurons that are strongly dark-dominated also tend to be less orientation-selective. This novel approach gives us new insight into the dark-dominance phenomenon and provides an avenue to address new questions about excitatory and inhibitory integration in cortical neurons.

SIGNIFICANCE STATEMENTNeurons in the early visual cortex respond on average more strongly to dark than to light stimuli, but the mechanisms behind this bias have been unclear. Here we address this issue by combining single-unit electrophysiology with a novel machine learning model to analyze neurons' responses to natural image stimuli in primary visual cortex. Using these techniques, we find slower inhibition to light than to dark stimuli to be the leading mechanism behind stronger dark responses. This slower inhibition to light might help explain other empirical findings, such as why orientation selectivity is weaker at earlier response latencies. These results demonstrate how imbalances in excitation versus inhibition can give rise to response asymmetries in cortical neuron responses.
Epilepsy-Related CDKL5 Deficiency Slows Synaptic Vesicle Endocytosis in Central Nerve Terminals

Published: February 2023

Cyclin-dependent kinase-like 5 (CDKL5) deficiency disorder (CDD) is a severe early-onset epileptic encephalopathy resulting mainly fromde novomutations in the X-linkedCDKL5gene. To determine whether loss of presynaptic CDKL5 function contributes to CDD, we examined synaptic vesicle (SV) recycling in primary hippocampal neurons generated fromCdkl5knockout rat males. Using a genetically encoded reporter, we revealed that CDKL5 is selectively required for efficient SV endocytosis. We showed that CDKL5 kinase activity is both necessary and sufficient for optimal SV endocytosis, since kinase-inactive mutations failed to correct endocytosis inCdkl5knockout neurons, whereas the isolated CDKL5 kinase domain fully restored SV endocytosis kinetics. Finally, we demonstrated that CDKL5-mediated phosphorylation of amphiphysin 1, a putative presynaptic target, is not required for CDKL5-dependent control of SV endocytosis. Overall, our findings reveal a key presynaptic role for CDKL5 kinase activity and enhance our insight into how its dysfunction may culminate in CDD.

SIGNIFICANCE STATEMENTLoss of cyclin-dependent kinase like 5 (CDKL5) function is a leading cause of monogenic childhood epileptic encephalopathy. However, information regarding its biological role is scarce. In this study, we reveal a selective presynaptic role for CDKL5 in synaptic vesicle endocytosis and that its protein kinase activity is both necessary and sufficient for this role. The isolated protein kinase domain is sufficient to correct this loss of function, which may facilitate future gene therapy strategies if presynaptic dysfunction is proven to be central to the disorder. It also reveals that a CDKL5-specific substrate is located at the presynapse, the phosphorylation of which is required for optimal SV endocytosis.

The graphene/carbon hybrid nanofibers decorated with vanadium-doped TiO2 nanoparticles (G/CF/V-TiO2) were successfully prepared by electrospinning technique and carbonization. The product was characterized by scanning and transmission electron microscopy, X-ray diffractometry, ultraviolet-visible diffuse reflectance spectroscopy, and photoluminescence spectroscopy. Results showed that the graphene/carbon nanofibers had a continuous fiber structure with uniform distribution of V-TiO2 nanoparticles on their surface. In the photodegradation of methylene blue (MB), G/CF/V-TiO2 showed a significant increase in the reaction rate under visible light. The enhanced photocatalytic activity could be ascribed to the doping of V into TiO2 and the carbon-based photocatalytic system, which resulted in an effective visible light response and a rapid separation of photoinduced electron-hole pairs. The strategy presented here can be adopted for synthesizing highly efficient visible-light-driven photocatalysts

The photo electronic devices based on surface plasmon resonance (SPR) phenomena have wide applications in the biomedical field. The biological environments to be detected are influenced by the SPR phenomenon, perhaps by the wavelength or the angle of incidence of resonance. In this work, the angular analysis of the phenomenon of double SPR in multilayer nanostructures is modeled by the transfer matrix method (T matrix). Consequently, we find that we can eliminate the error of simple SPR response and double SPR response based on the absolute deference response between the first SPR resonance and the second SPR double resonance.

Due to its toxicity, destruction of H2S gas has been an important topic of researchers. Many studies have been carried for investigating various techniques for the removal of this gas. One of those techniques is catalytic and photocatalytic destruction of H2S gas using various catalysts including TiO2 owing to its significant potential for degradation of various pollutants. This study investigates the destruction potential of Zr doped TiO2 for the abatement of H2S gas. The catalysts were characterized using different techniques like XRD, SEM, XRF. The catalytic experiments were performed using fixed bed catalyst system. The samples were analyzed using GC-MC technique and it was revealed that the Zr doping of TiO2 did not favour positively towards enhancing the H2S destruction potential as found in other studies.

Malachite green dye has been known to have toxic carcinogenic characteristics and potential health risks for humans even at low concentrations. Hence, it is very vital to remediate the dye before discharge into water bodies or water treatment systems. Thus, this article demonstrated the removal of cleanup of malachite green (MG)dye from the aquatic phase using ZnO nanopowder. In this work batch adsorption experiments were accomplished as a function of contact time, pH, and initial dye concentration to study the efficiency of ZnO nanopowder on dye removal (MG). The obtained nanopowder was characterized using various techniques XRD, FTIR, SEM and EDX. The results shown that the maximum absorbed value was 233.16 mg / g. The findings show that ZnO nanopowder have fast contact time and initial concentration absorbing characteristics in dye removal. The maximum capacity of sorbent was found to be 246.36 mg. Furthermore, the study revealed that ZnO nanopowder is an effective sorbent for cleanup of malachite green dye in aqueous solution when comparing with other adsorbent materials.

O estudo objetivou identificar o seguimento do princípio da atenção básica acesso de primeiro contato, em unidades básicas de saúde, no cuidado de saúde para crianças menores de cinco anos, com problemas respiratórios. Estudo qualitativo, hermenêutico, cuja base conceitual está centrada no cuidado. A parte empírica consiste de entrevistas com acompanhantes de crianças hospitalizadas e profissionais de saúde de unidades básicas de saúde e de emergência. A compreensão dos dados por meio da linguagem hermenêutica norteia a análise. Os resultados mostram que o acesso de primeiro contato está ocorrendo em unidades de emergência para atenção a episódios agudos de problemas de saúde em vez de unidades de atenção básica, sem ações programáticas e acolhimento como metodologia de ação cotidiana, que a atenção básica não atua como reguladora do sistema de saúde, sendo necessário refletir sobre seu papel como integrante dos serviços de saúde e a retomada de sua função

O atendimento à parada cardiorrespiratória deve ser realizado de maneira sistematizada, baseada nos protocolos de suporte básico e avançado de vida. O objetivo desse estudo é avaliar o conhecimento da equipe de enfermagem de uma unidade de terapia intensiva em relação ao reconhecimento da parada cardiorrespiratória e a instituição de manobras de reanimação conforme os protocolos. Trata-se de estudo descritivo e quantitativo, realizado no período de abril a junho de 2011. Dos 33 profissionais que participaram do estudo 54,5% não haviam feito capacitação prévia sobre o tema; 93,9% acertaram parcialmente os ritmos de parada; apenas 15,2% acertaram totalmente as manobras de ventilação no paciente intubado. O baixo índice de acertos totais demonstra a necessidade de atualização da equipe de enfermagem, com capacitação teórico-prática de maneira periódica, e avaliações sistemáticas da atuação dessa equipe.

Técnicas antropométricas, que estabeleçam o diagnóstico de sobrepeso/obesidade, como o Índice de Massa Corporal (IMC) e a Circunferência Abdominal (CA), são cada vez mais importantes. Objetivou-se conhecer o IMC e relacionar com a CA de adolescentes escolares de duas instituições piauienses. Estudo descritivo e transversal de prevalência quantitativa, realizado em duas escolas públicas de Picos - PI, com 145 adolescentes com idade entre 12 e 18 anos de ambos os sexos. A coleta dos dados foi realizada através de um formulário nos meses de agosto a dezembro de 2010. A prevalência de excesso de peso foi de 3,7%. O excesso de peso encontrou-se associado ao aumento da CA (< 0,0001). Esses resultados reforçam a pertinência de se realizar ações de prevenção e controle do excesso de peso a fim de que a saúde dos adolescentes seja mantida.

A rede social de apoio é constituída do conjunto de vínculos relacionados ao indivíduo. Considerando-se que, tanto a qualidade, quanto a quantidade desses vínculos podem interferir na vida da pessoa, atuando como elemento positivo ou negativo, identifica-se a necessidade do conhecimento dessa rede de relações pelos profissionais que cuidam dessas pessoas. Objetivou-se analisar o ecomapa de usuários de drogas assistidos em um serviço especializado como instrumental de apoio para a assistência em saúde. Pesquisa qualitativa, realizada com 19 sujeitos assistidos em um serviço público, através da elaboração do ecomapa. Resultados evidenciam que CAPSad, família e religião constituíram vínculos fortes; trabalho, companheiros e amigos, vínculos a serem fortalecidos.Vizinhos e ex-companheiros usuários de drogas foram mencionados como estressores. O ecomapa se mostrou um instrumento de avaliação que pode ser utilizado para ajudar o usuário a trabalhar seus vínculos, destacando-se aqueles que precisam ser mantidos, rompidos ou fortalecidos como suporte social.

Objetivou-se descrever as características sociodemográficas e funcionais do idoso após o acidente vascular encefálico isquêmico. Estudo descritivo, quantitativo, realizado com amostra de acessibilidade de 52 idosos acometidos por acidente vascular encefálico isquêmico, em serviço de saúde de Fortaleza-CE-Brasil, entre maio e agosto de 2009. Calcularam-se média e desvio padrão para as variáveis contínuas e teste qui-quadrado para comparar proporções nas variáveis categóricas. Os resultados mostraram que 37 (71,2%) estavam entre 60 e 79 anos de idade, 43 (82,7%) residiam em Fortaleza, 30 (57,7%) eram casados, com renda familiar média de 2,5 salários mínimos e 16 (30,8%) tinham histórico da doença na família. A proporção de idosos se distribuiu de maneira uniforme nas faixas de incapacidade funcional e de dependência (p=0,972 e p=0,780). O conhecimento do perfil desses idosos é fundamental, pois a qualidade de vida destes tem estreita ligação com a realidade social e econômica, bem como a capacidade funcional.
