Dual roles of inorganic aqueous phase on SOA growth from benzene and phenol
Authors: Choi Jiwon , Jang Myoseon , Blau Spencer
Published: November 2023

Abstract. Benzene, emitted from automobile exhaust and biomass burning, is ubiquitous in ambient air. Benzene is a precursor hydrocarbon (HC) that forms secondary organic aerosols (SOA), but its SOA formation mechanism is not well studied. To accurately predict the formation of benzene SOA, it is important to understand the gas mechanisms of phenol, which is one of the major products formed from the atmospheric oxidation of benzene. Our chamber study found that wet-inorganic aerosol retarded the gas oxidation or phenol or benzene, and thus their SOA formation. To explain this unusual effect, it is hypothesized that a persistent phenoxy radical (PPR) effectively forms via a heterogeneous reaction of phenol and phenol-related products in the presence of wet-inorganic aerosol. These PPR species are capable of catalytically consuming ozone during a NOx cycle and negatively influencing SOA growth. In this study, explicit gas mechanisms were derived to produce the oxygenated products from the atmospheric oxidation of phenol and benzene. Gas mechanisms include the existing Master Chemical Mechanism (MCM v3.3.1); the reaction path for peroxy radical adducts originating from the addition of an OH radical to phenols forming low-volatility products (e.g., multi-hydroxy aromatics); and the mechanisms to form heterogeneous production of PPR. The simulated gas products were classified into volatility-reactivity based lumping species and incorporated into the UNIfied Partitioning Aerosol Reaction (UNIPAR) model that predicts SOA formation via multiphase reactions of phenol or benzene. The predictability of the UNIPAR model was examined using chamber data, which were generated for the photooxidation of phenol or benzene under various experimental conditions (NOx levels, humidity, and inorganic seed types). The SOA formation from both phenol and benzene still increased in the presence of wet inorganic seed because of the oligomerization of reactive organic species in aqueous phase. However, model simulations show a significant suppression in ozone, the oxidation of phenol or benzene, and SOA growth, compared to those without PPR mechanisms. In addition, the production of PPR is accelerated in the presence of acidic aerosol and this weakens SOA growth. In benzene oxidation, about 53 % of the oxidation pathway is connected to phenol formation in the reported gas mechanism. Thus, the contribution of PPR to gas mechanisms is less than phenol. Overall, SOA growth in phenol or benzene is negatively related to NOx levels in the high NOx region (HC ppbC/NOx ppb <5). However, the simulation indicates that the significance of PPR rises with decreasing NOx levels. Hence, the influence of NOx levels on the SOA formation from phenol or benzene is complex under varying temperature and seed types.

Abstract. The Greenland Ice Sheet is a key contributor to contemporary global sea level rise, but its long-term history and response to episodes of warming in Earth’s geological past remain uncertain. The terrain covered by the ice sheet comprises ~79 % of Greenland and ~1.1 % of the Earth’s land surface and contains geomorphological records that may provide valuable insights into past ice-sheet behaviour. Here we use ice surface morphology and radio-echo sounding data to identify ice-covered valleys within the highlands of southern and eastern Greenland and use numerical ice-sheet modelling to constrain the climatological and glaciological conditions responsible for valley incision. Our mapping reveals intricate subglacial valley networks with morphologies that are indicative of substantial glacial modification of an inherited fluvial landscape, yet many of these valleys are presently situated beneath cold-based, slow-moving (i.e., non-erosive) ice. We use the morphology of the valleys and our simple ice-sheet model experiments to infer that incision likely occurred beneath erosive mountain valley glaciers during one or more phases of Greenland’s glacial history when ice was restricted to the southern and eastern highlands, and Greenland’s contribution to barystatic sea level was up to +7 metres relative to today. We infer that this valley incision primarily occurred prior to the growth of a continental-scale ice sheet, most likely during the late Miocene (ca. 7–5 Ma) and/or late Pliocene (ca. 3.6–2.6 Ma). Our findings therefore provide new data-based constraints on early Greenland Ice Sheet extent and dynamics that can serve as valuable boundary conditions in models of regional and global palaeoclimate during past warm periods that are important analogues for the 21st Century and beyond.

Abstract. Central European winters have warmed markedly since the mid-20th century. Yet cold winters are still associated with severe societal impacts on energy systems, infrastructure and public health. It is therefore crucial to anticipate storylines of worst-case cold winter conditions, and to understand whether an extremely cold winter, such as the coldest winter in the historical record of Germany in 1963 (−6.3 °C or −3.4σ seasonal DJF temperature anomaly relative to 1981–2010), is still possible in a warming climate. Here, we first show based on multiple attribution methods that a winter of similar circulation conditions to 1963 would still lead to an extreme seasonal cold anomaly of about −4.9 to −4.7 °C (best estimates across methods) under present-day climate. This would rank as second-coldest winter in the last 75 years. Second, we conceive storylines of worst-case cold winter conditions based on two independent rare event sampling methods (climate model boosting and empirical importance sampling): winter as cold as 1963 is still physically possible in Central Europe today, albeit very unlikely. While cold winter hazards become less frequent and less intense in a warming climate overall, it remains crucial to anticipate the possibility of an extreme cold winter to avoid potential maladaptation and increased vulnerability.

Abstract. The temporal variation of the carbonate system, air-sea CO2 fluxes and pH is analyzed in the Southern Indian Ocean, south of the Polar Front, based on in-situ data obtained from 1985 to 2021 at a fixed station (50°40’S–68°25’E) and results from a neural network model that reconstructs the fugacity of CO2 (fCO2) and fluxes at monthly scale. Anthropogenic CO2 (Cant) was estimated in the water column and detected down to the bottom (1600 m) in 1985 resulting in an aragonite saturation horizon at 600 m that migrated up to 400 m in 2021 due to the accumulation of Cant. In subsurface, the trend of Cant is estimated at +0.53 (±0.01) µmol.kg-1.yr-1 with a detectable increase in recent years. At the surface during austral winter the oceanic fCO2 increased at a rate close or slightly lower than in the atmosphere. To the contrary, in summer, we observed contrasting fCO2 and dissolved inorganic carbon (CT) trends depending on the decade and emphasizing the role of biological drivers on air-sea CO2 fluxes and pH inter-annual variability. The region moved from an annual source of 0.8 molC.m-2.yr-1 in 1985 to a sink of -0.5 molC.m-2.yr-1 in 2020. In 1985–2020, the annual pH trend in surface of -0.0165 (± 0.0040).decade-1 was mainly controlled by anthropogenic CO2 but the trend was modulated by natural processes. Using historical data from November 1962 we estimated the long-term trend for fCO2, CT and pH confirming that the progressive acidification was driven by atmospheric CO2 increase. In 59 years this leads to a diminution of 11 % for both aragonite and calcite saturation state. As atmospheric CO2 will desperately continue rising in the future, the pH and carbonate saturation state will decrease at a faster rate than observed in recent years. A projection of future CT concentrations for a high emission scenario (SSP5-8.5) indicates that the surface pH in 2100 would decrease to 7.32 in winter. This is up to -0.86 lower than pre-industrial pH and -0.71 lower than pH observed in 2020. The aragonite under-saturation in surface waters would be reached as soon as 2050 (scenario SSP5-8.5) and 20 years later for a stabilization scenario (SSP2-4.5) with potential impacts on phytoplankton species and higher trophic levels in the rich ecosystems of the Kerguelen Island area.

Abstract. The main contributor to the greenhouse gas (GHG) footprint of the cement industry is the decomposition of alkaline carbonates during clinker production. However, systematic accounts for the reverse of this process – namely carbonation of calcium oxide and other alkaline oxides and/or hydroxides within cement materials during cements' life cycles – have only recently been undertaken. Here, adopting a comprehensive analytical model, we provide the most updated estimates of CO2 uptake by cement carbonation. The accumulated amount of global CO2 uptake by cements produced from 1930 to 2021 is estimated to be 22.9 Gt CO2 (95 % confidence interval, CI: 19.6–26.6 Gt CO2). This amount includes the CO2 uptake by concrete, mortar, construction waste and kiln dust, accounting for 30.1 %, 58.5 %, 4.0 % and 7.1 % respectively. The cumulative carbon uptake by cement materials from 1930 to 2021 offsets 55.1 % of the emissions from cement production (41.6 Gt CO2, 95 % CI: 38.7–47.2 Gt CO2) over the same period, with the greater part coming from mortar (58.5 % of the total uptake). China has the highest cement carbon uptake, with cumulative carbonation of 7.06 Gt CO2 (95 % CI: 5.22–9.44 Gt CO2) since 1930. In addition, the carbon uptake amounts of the USA, EU, India and the rest of the world took 5.0 %, 23.2 %, 5.6 % and 34.8 % separately. As a result of rapidly increased production in recent years, over three-quarters of the cement carbon uptake has occurred since 1990. Additionally, our results show little impact by the COVID-19 pandemic on cement production and use, with carbon uptake reaching about 0.92 Gt CO2 (95 % CI: 0.78–1.10 Gt CO2) in 2020 and 0.96 Gt CO2 (95 % CI: 0.81–1.15 Gt CO2) in 2021. Our uniformly formatted and most updated cement uptake inventories provide coherent data-based support for including cement carbon uptake into future carbon budgets from the local to global scale. The latest version contains the uptake data till 2021, showing the global uptake's increasing pattern and offering more usable and relevant data for evaluating cement's carbon uptake capacity.

Published: November 2023

Abstract. As earth system modeling develops ever finer grid resolutions, the inputting and outputting (I/O) of the increasingly large data fields becomes a processing bottleneck. Many models developed in China, as well as the community coupler (C-Coupler), do not fully benefit from existing parallel I/O supports. This paper reports the design and implementation of a common parallel input/output framework (CIOFC1.0) based on C-Coupler2.0. The CIOFC1.0 framework can accelerate the I/O of large data fields by parallelizing data read/write operations among processes. The framework also allows convenient specification by users of the I/O settings, e.g., the data fields for I/O, the time series of the data files for I/O, and the data grids in the files. The framework can also adaptively input data fields from a time series dataset during model integration, automatically interpolate data when necessary, and output fields either periodically or irregularly. CIOFC1.0 demonstrates the cooperative development of an I/O framework and coupler, and thus enables convenient and simultaneous use of a coupler and an I/O framework.
IMEX_SfloW2D v2: a depth-averaged numerical flow model for volcanic gas–particle flows over complex topographies and water
Authors: de' Michieli Vitturi Mattia , Esposti Ongaro Tomaso , Engwell Samantha
Published: November 2023

Abstract. We present developments to the physical model and the open-source numerical code IMEX_SfloW2D (de' Michieli Vitturi et al., 2019). These developments consist of a generalization of the depth-averaged (shallow-water) fluid equations to describe a polydisperse fluid–solid mixture, including terms for sedimentation and entrainment, transport equations for solid particles of different sizes, transport equations for different components of the carrier phase, and an equation for temperature/energy. Of relevance for the simulation of volcanic mass flows, vaporization and entrainment of water are implemented in the new model. The model can be easily adapted to simulate a wide range of volcanic mass flows (pyroclastic avalanches, lahars, pyroclastic surges), and here we present its application to transient dilute pyroclastic density currents (PDCs). The numerical algorithm and the code have been improved to allow for simulation of sub- to supercritical regimes and to simplify the setting of initial and boundary conditions. The code is open-source. The results of synthetic numerical benchmarks demonstrate the robustness of the numerical code in simulating transcritical flows interacting with the topography. Moreover, they highlight the importance of simulating transient in comparison to steady-state flows and flows in 2D versus 1D. Finally, we demonstrate the model capabilities to simulate a complex natural case involving the propagation of PDCs over the sea surface and across topographic obstacles, through application to Krakatau volcano, showing the relevance, at a large scale, of non-linear fluid dynamic features, such as hydraulic jumps and von Kármán vortices, to flow conditions such as velocity and runout.
Strategies for Comparison of Modern Probabilistic Seismic Hazard Models and Insights from the Germany and France Border Region

Published: November 2023

Abstract. The latest generation of national and regional probabilistic seismic hazard assessments (PSHA) in Europe presents stakeholders with multiple representations of the hazard in many regions. This raises the question of why and by how much seismic hazard estimates between two or more models differ, not where models overlap geographically but also where new models update existing ones. As modern PSHA incorporates increasingly complex analysis of epistemic uncertainty, the resulting hazard is represented not as a single value or spectrum but rather as probability distribution. Focusing on recent PSHA models for France and Germany, alongside the 2020 European Seismic Hazard Model, we explore the differences in model components and highlight the challenges and strategy for harmonising the different models into a common PSHA calculation software. We then quantify the differences in the source model and seismic hazard probability distributions using metrics based on information theory, illustrating their application to Upper Rhine Graben region. Our analyses reveal the spatial variation and complexity of model differences when viewed as probability distributions and highlight the need for more detailed transparency and replicability of the models when used as a basis for decision making and engineering design.
The influence of extraction of various solvents on chemical properties on Chang 7 shale, Ordos Basin, China

Published: November 2023

Abstract. To explore the effect of various solvents extraction on the chemical property of shale, several lacustrine shale samples from the Chang 7 member of the Upper Triassic Yanchang Formation, Ordos Basin, with maturities, from marginally mature (Tmax=439∘) to late mature (Tmax=456∘), were extracted by using acetone, tetrahydrofuran (THF), carbon disulfide (CS2), and benzene, respectively. Fourier transform infrared spectroscopy (FTIR) was employed to examine the functional groups of the samples before and after extraction with different solvents. The results showed that the extraction yield from shale with THF is significantly higher than that of other solvents, which may be related to the properties of the THF, including the aromatic structure, high boiling point, excellent Hansen solubility parameters, and strong polarity. The total organic carbon (TOC)-normalized yield of the mature sample J1 is significantly higher than that of other samples, which may be related to the fact that the J1 sample is at the peak of hydrocarbon generation; thus, a large number of kerogens were cracked into oil and bitumen. The aromaticity of organic matter (OM) increases with the increase in the maturity. The length of the aliphatic chains of the OM first increased with the increase in the maturity before late maturity stage and then decreased in late maturity stage. The extraction of shale samples with solvents hardly changes the length of aliphatic chains. Higher aromaticity is observed in shale residues after THF extractions than for other solvents (i.e., acetone, CS2, and benzene).

Published: November 2023

The optimal management of trapeziometacarpal (TMC) osteoarthritis remains controversial. This meta-analysis assessed the subjective and objective outcomes of trapeziometacarpal arthrodesis (TMA) versus trapeziec-tomy with ligament reconstruction (LRTI). The PubMed, Cochrane Library, Embase, Web of science data-bases were searched from inception to June 30, 2022. Keywords included “trapeziometacarpal osteoarthrosis”, “trapeziometacarpal arthrodesis” and “trapeziectomy with ligament reconstruction”. Randomized controlled trials (RCTs) and controlled clinical trials (CCTs) including patients treated for TMC osteoarthritis were included. The subjective outcomes visual analogue scale (VAS) , Patient-Rated Wrist and Hand Evaluation (PRWHE), Disabilities of arm, shoulder and hand (DASH) scores, Kapanji scores, objective outcomes total interphalangeal (IP) and metacarpophalangeal (MCP) joint motion, palmar abduction, grip strength, tip, key pinch strength and complications were extracted. The methodological quality of each was assessed in- dependently. Meta-analysis was performed for comparative trials.

From the 5 included studies (2 RCTs, 3 CCTs), 208 cases were divided into TMA group (n = 107) and LRTI group (n =101) groups. Compared with the TMA group, PRWHE, tip pinch strength and palmar abduction was better in the LRTI group. There was no statistical difference in DASH score, VAS, kapandji score, grip strength, key pinch strength, total IP joint motion, total MCP joint motion and complications. The LRTI group had more obvious advantages in term of PRWHE, tip pinch strength and palmar abduction. Moreover, there was no statistical difference in DASH score, VAS, kapandji score, grip strength, key pinch strength, total IP joint and total MCP joint motion and complications. Therefore, we concluded LRTI was more recommendable for more management of TMC osteoarthritis. Certainly, high-quality studies are required in long-term follow-up.
Bicruciate retaining total knee arthroplasty: current state and future promise
Authors: COOLS A.-S. , LUYCKX T , VICTOR J , ARNOUT N
Published: November 2023

Total knee arthroplasty (TKA) is a well-known surgical procedure performed to address end stage osteoarthritis. The main goal is to relieve pain, recover articular function and return to normal function as soon as possible. Over the years it is frequently performed in the elderly, but lately there is an increased demand in a younger and more active population. Up to 25% of patients feel dissatisfied about their TKA. The anterior cruciate ligament (ACL) is considered the main anteroposterior stabilizer of the knee; nevertheless the ACL is usually sacrificed during conventional TKA. Research shows this might be an unnecessary sacrifice in certain cases. The considerable dissatisfaction rate in mainly high-demanding patients, together with the literature reports on the importance of the ACL function, were the two main reasons for the development of bicruciate retaining (BCR) total knee arthroplasty. BCR TKA may offer superior knee kinematics and proprioception, through anterior cruciate ligament preservation, but requires a higher level of attention to obtain an accurate and precise component orientation to reach proper ligamentous balancing and restore the native knee biomechanics. Many surgeons abandoned its use due to its challenging technique and inconsistent results. Recent new BCR implant designs are promising. This systematic literature review aims to summarize the current state of BCR TKA and what to expect in the future.

First-principles theory of electrochemical capacitance
Authors: Binninger Tobias
Published: November 2023

Understanding and interpreting electrochemical capacitance has advanced both theory and experiment in electrochemistry for more than a century. From a theoretical perspective, the interfacial capacitance is commonly defined based on the original notion of the interfacial Galvani potential, i.e., the inner electric potential difference between electrode and electrolyte phases. With the emergence of accurate first-principles methods, the atomistic simulation of the capacitive properties of electrochemical systems is gaining significant attention. At the atomistic level, however, the classical picture of inner potentials becomes questionable and new concepts are required, e.g., to explain electronic ‘quantum’ contributions to the capacitance of low-dimensional electrodes. In this seminar talk, I will present a new approach to describe electrochemical capacitance based on multicomponent density functional theory (MCDFT), which is a general formalism to treat multicomponent systems including electrons and ions/nuclei from first principles. It will be shown that MCDFT provides the conceptual framework needed to formulate a “modern” theory of electrochemical capacitance, connecting classical concepts of double-layer capacitance, quantum capacitance, and, eventually, reactive (pseudo)capacitance contributions. The formalism yields exact analytical expressions for the total capacitance incorporating electric and non-electric capacitance contributions. In the bulk limit of extended electrode and electrolyte phases, it is shown to reduce to the known classical expressions, providing firm basis for the classical approach based on the concept of Galvani potentials. Future opportunities towards a modern theory of capacitance will be discussed.
Interpreting the Egyptian Code in Nineteenth-Century China: Pan Zuyin and His Circle of Antiquarians
Authors: Chen Helena
Published: November 2023

Antiquarianism in China experienced a dramatic change in the second half of the nineteenth century. While ancient Chinese artifacts were still eagerly sought after, scholars began to collect Egyptian inscriptions. Unequipped with any knowledge of the Egyptian writing system, they were fascinated by the stylistic similarity between Egyptian hieroglyphs and ancient Chinese seal-script characters. This article centers on the scholar-official Pan Zuyin (1830–90) and his collection of ink rubbings of the Decree of Canopus, a stele with trilingual inscriptions carved in the Ptolemaic era. It examines how Qing antiquarians interpreted ancient Egyptian inscriptions, adapting, denying, and transforming Champollion’s approach by explaining the formation and evolution of the Egyptian writing system in terms of their own philological theory, the liushu (the six modes of character formation). It argues that the craze for Egyptian inscriptions resulted from discursive changes occurring in the field of antiquarian study as the scope of acceptable research areas was broadened and the strange and exotic objects—previously considered uncollectible—began to attract scholarly attention. The popularity of Egyptian inscriptions also demonstrates that serious philological study and an amateurish pleasure-seeking attitude were not so much oppositional binaries as interdependent activities.

Foram investigados o perfil de ácidos graxos, a composição centesimal, o valor calórico e o teor de colesterol em duas espécies de peixes marinhos do Estado de Alagoas: carapeba-listrada (Eugerres plumieri Cuvier, 1830) e a cavala (Scomberomorus cavalla Cuvier, 1829), analisando-se 20 amostras de cada espécie. Elevado teor de umidade foi observado na amostra de carapeba-listrada, assim como os maiores valores de proteínas e cinzas, em base úmida, foram detectados nesta citada espécie. Quanto aos lipídeos, os valores obtidos para as duas espécies foram iguais, em base úmida. As amostras de cavala apresentaram o maior valor calórico, bem como o teor de colesterol mais elevado em base úmida. No perfil de ácidos graxos, a cavala apresentou percentuais mais elevados de monoinsaturado oleico (7,74%) e de poli-insaturados: linoleico (6,91%),α-linolênico (2,90%), EPA (10,82%), e DHA (4,50%). A relação poli-insaturados/saturados foi mais elevada na cavala (0,95), bem como o somatório dos teores de EPA + DHA (15,32). Na avaliação da qualidade nutricional dos lipídeos, as espécies estudadas mostraram os índices de n-6/n-3, hipocolesterolêmicos /hipercolesterolêmicos (HH), índice de aterogenicidade (IA) e índice de trombogenicidade (IT) favoráveis para o consumo alimentar. Considerando-se os resultados obtidos, a espécie cavala pode ser considerada boa fonte de ácidos graxos, principalmente o ácido ômega-3 e pelo seu valor em HH.

Published: November 2023

Introducción. El desempeño de roles ocupacionales puede ser una fuente de estrés, tensión y conflicto, pero también puede estar relacionado con experimentar satisfacción vital. Diversos estudios se han llevado a cabo en población general, y también especialmente en personas mayores con el objetivo de analizar esta relación. No obstante, no existen investigaciones al respecto en población adulta con discapacidad física. El objetivo de este estudio fue analizar la influencia de presentar discapacidad física en la relación entre los roles y la satisfacción vital en personas adultas. Método. Se trató de un estudio transversal analítico, en el que 42 personas adultas con discapacidad física y 41 sin discapacidad respondieron a la Escala de Satisfacción Vital y a un Cuestionario sobre roles ocupacionales en el que se recogió información sobre número de roles, aspectos volicionales de éstos y tiempo empleado. Resultados. Los resultados mostraron una correlación significativa y positiva entre el número de roles y el tiempo dedicado a su desempeño y la satisfacción vital sólo en personas con discapacidad física. La interacción entre la presencia de discapacidad y número de roles fue una variable predictora significativa para la satisfacción vital. Sin embargo, no se encontró relación entre la volición de los roles desempeñados y la satisfacción vital en ningún grupo. Conclusiones. Estos resultados evidencian la importancia de incorporar intervenciones que incrementen la participación en varios roles para las personas con discapacidad física.

A paralisia cerebral (PC) acomete o indivíduo de diferentes formas, dependendo da área do sistema nervoso afetada. O individuo com PC apresenta alterações neuromusculares, como variações de tônus muscular, persistência de reflexos primitivos, rigidez, espasticidade, entre outros. Consequentemente, interfere de forma importante na interação da criança em contextos relevantes, influenciando, assim, a aquisição e o desempenho não só de marcos motores básicos (rolar, sentar, etc.), mas também de atividades da rotina diária, como tomar banho, alimentar-se, vestir-se, locomover-se em ambientes variados e o brincar. O objetivo desse estudo é investigar se existe relação entre o brincar da criança com PC e o seu desempenho comunicativo e motor. Participaram da pesquisa 20 crianças com PC na faixa etária de 3 a 12 anos que frequentam salas regulares de ensino, bem como seus professores. Para classificação das crianças foi utilizado um instrumento para a avaliação do brincar e os instrumentos GMFCS, MACS E CFCS. A pesquisa foi realizada no período de 2014 a 2015 através da observação das crianças e preenchimento de uma avaliação por duas graduandas em Terapia Ocupacional. Ao final desse estudo foi possível concluir que existe uma relação entre o brincar e desempenho motor das crianças com PC.
Los significados construidos del envejecimiento positivo en la participación ocupacional de adultas mayores con patologías articulares.

Published: November 2023

El envejecimiento de las personas ha generado un aumento de adultos mayores, gran porcentaje de éstos son mujeres. También han incrementado las enfermedades crónicas, siendo más frecuentes en esta población las patologías articulares, que impactan en la funcionalidad y la calidad de vida, contribuyendo a la creencia de mitos en torno a la vejez. No obstante, esta visión cambiaría, debido a la creación de una propuesta política gubernamental como la de Envejecimiento Positivo, orientada a la inclusión del adulto mayor en la sociedad, mejorando su calidad de vida y posicionándolo como un sujeto de derecho.

La Terapia Ocupacional promueve la participación ocupacional de adultas mayores con enfermedades articulares, para que tengan un envejecimiento positivo, pero para alcanzar ese propósito, es preciso analizar el significado construido que tienen estas personas sobre dicho concepto, por esto se realizó una entrevista semiestructurada a 4 mujeres entre 61 y 68 años de edad, cuyos temas se basaron en el bienestar subjetivo, la salud, la participación social y la participación ocupacional en el tiempo libre, elementos relevantes en el envejecimiento positivo.

Mediante el análisis de datos con la Teoría Fundamentada, se estudió el significado construido sobre el envejecimiento positivo, concebido por las participantes, como una educación del envejecimiento, para así no depender de otros. También se visualizó el envejecimiento como sinónimo de vejez, el que se vivencia como una etapa de soledad, en la que, si bien, la calidad de vida no se ve afectada por éste, hay factores que influyen en ella, afectando sus capacidades motoras, por ello desarrollan principalmente ocupaciones de tiempo libre pasivas, con deseos de efectuar actividades recreativas.

Objetivos: describir la percepción estudiantil en las carreras de Fonoaudiología, Obstetricia y Terapia Ocupacional respecto a la formación bioética en pregrado y su aplicabilidad al inicio de su experiencia práctica profesional.
Método: estudio descriptivo transversal; se diseñó y aplicó una encuesta a 147 estudiantes, correspondiendo un 29,9% a la Escuela de Fonoaudiología, 42,2% a la Escuela de Obstetricia y 18,4% a la Escuela de Terapia Ocupacional. Las aseveraciones fueron dirigidas a indagar sobre: conocimientos, actitudes y aplicabilidad de los conocimientos en el ámbito clínico asistencial. Se realizó análisis estadístico simple de frecuencia.
Resultados: 99,3% de los estudiantes encuestados refiere que está muy de acuerdo y de acuerdo con la relevancia de esta formación bioética, 85% reconoce estar muy de acuerdo y de acuerdo en utilizar regularmente sus conocimientos de bioética en la práctica clínica.
Conclusiones: los estudiantes de las tres carreras, perciben muy relevante la formación en bioética durante el pregrado y de alta aplicabilidad en el contexto clínico. En el actual proceso de innovación curricular se sugiere que la enseñanza bioética de futuros profesionales de la salud, tenga un enfoque más práctico orientado a lo clínico.

Trata-se de um estudo descritivo-exploratório, com abordagem qualitativa, realizado no Núcleo de Apoio à Criança e adolescente com Câncer, em João Pessoa, Paraíba. Teve como objetivo conhecer as experiências de familiares cuidadores de crianças e adolescentes com câncer. Participaram da pesquisa oito cuidadoras que residiam em diferentes municípios do estado. Utilizou-se como instrumento de coleta de dados uma entrevista semiestruturada, realizada nos meses de fevereiro e março de 2018. A análise do material coletado foi realizada mediante a análise de conteúdo temática. O estudo obedeceu à Resolução 466/12, do Conselho Nacional de Saúde. Os achados evidenciaram o surgimento de três categorias principais: Categoria 1: mulheres cuidadoras relatam mudanças em suas rotinas de vida depois que os familiares iniciaram o tratamento contra o câncer; Categoria 2: principais dificuldades enfrentadas pelas cuidadoras no processo de cuidar da criança e do adolescente com câncer e Categoria 3: estratégias de promoção de saúde mental de cuidadoras de crianças e adolescentes com câncer. Identificou-se que as familiares cuidadoras apresentam demandas de cuidado, pois múltiplos aspectos de suas vidas sofreram mudanças significativas desde que iniciaram o tratamento de seus familiares com câncer. As cuidadoras enfrentam dificuldades nas dimensões física, psicológica e financeira, correlacionadas ao processo de cuidado prestado, dentre outros aspectos importantes.

Se propone una reflexión respecto de la importancia de haber realizado una estadía en el extranjero (Italia) durante el proceso de formación de doctorado en Brasil, con énfasis en el método etnográfico como estrategia de intervención para la Terapia Ocupacional y la posibilidad de comparar los escenarios en salud mental vigentes en ambos contextos.
Esta experiencia fue posible en el marco del Programa de Doctorado Sándwich en el Extranjero, financiado por el Programa de Ciencia sin Fronteras del Consejo Nacional de Desarrollo Científico y Tecnológico de Brasil, y consistió en una estadía como investigador en el Departamento de Filosofía, Ciencias Sociales, Humanidades y Educación de la Universidad Degli Studi di Perugia, Italia, entre el 1º de febrero de 2015 y el 31 de julio de 2015. Se realizó una inmersión en servicios de salud mental de la ciudad de Perúgia, en la región de Úmbria y una visita a la ciudad de Trieste con el objetivo de conocer la historia de la reforma psiquiátrica en Italia y la organización de la red y de los servicios. Durante este periodo fue posible participar de seminarios relacionados con el tema de salud mental, clases de antropología y acompañamiento terapéutico en los servicios de salud mental, manteniendo contacto con profesores, profesionales y usuarios. Todo lo anterior permitió hacer una revisión de datos respecto de la valoración y tipos de abordajes de aspecto de la vida cotidiana de los usuarios de los servicios de salud mental.
INTERVENCIONES DE TERAPIA OCUPACIONAL EN EL MANEJO DE SOBREPESO Y OBESIDAD: REVISIÓN SISTEMÁTICA EXPLORATORIA
Authors: Ortiz Rosa , Gajardo Jean
Published: November 2023

Introducción: Existe limitado conocimiento sobre las características y evidencia disponible de intervenciones de terapia ocupacional en el manejo y reducción de la obesidad y sobrepeso, traduciéndose en una limitada consideración en políticas y programas de salud.

Objetivo: Caracterizar las intervenciones de terapia ocupacional en sobrepeso y/u obesidad.

Métodos: Revisión Sistemática Exploratoria (Scoping Review) en las bases de datos EBSCOhost, Embase, PubMed, PsychInfo, Scielo y Scopus, de estudios publicados a junio 2020. Se usó estructura PRISMA ScR, incorporando artículos que cumplieran los criterios: a) Evaluasen una intervención de terapia ocupacional en sobrepeso y/u obesidad, b) Informasen resultados cuantitativos, y c) Publicados en revista con evaluación de pares.

Resultados: Cinco estudios fueron incluidos en la revisión. Cuatro utilizaron un diseño cuasi experimental (pretest-postest, sin grupo de comparación), y un estudio utilizó un diseño mixto con estudio pretest-postest adicionando estudio cualitativo. Las intervenciones son heterogéneas y sus resultados atribuibles no fueron significativos en el desenlace reducción de peso corporal. Se relevan resultados favorables en otras dimensiones, como la resignificación del uso de tiempo libre y el aprendizaje de hábitos saludables.

Discusión: Las intervenciones de terapia ocupacional refieren protocolos de intervención heterogéneos, asociados a programas de manejo de sobrepeso y obesidad. Los estudios disponibles proporcionan evidencia limitada su efectividad, y sus potenciales desenlaces son más consistentes con dimensiones psicosociales por sobre dimensiones morfológicas como el peso corporal. Se requiere con urgencia investigación experimental que permita establecer la acción de terapia ocupacional en estos problemas de relevancia para la salud pública.

Published: November 2023

Esta pesquisa teve como objetivo compreender o significado de ocupar-se como cuidador da pessoa sob cuidados paliativos oncológicos. Trata-se de uma pesquisa de abordagem qualitativa realizada em um hospital referência na assistência paliativa oncológica da região norte do Brasil, na qual participaram 20 cuidadores principais de pessoas internadas na Clínica de Cuidados Paliativos Oncológicos – CCPO em fase avançada da doença e morte iminente. Nas respostas desses entrevistados, destacam-se o cuidar como doação, a percepção de entrega referente ao ato de cuidar e ainda, a vontade de estar ao lado de quem recebe seus cuidados independente do que possa acontecer, incluindo o óbito. Do ponto de vista ocupacional, investir em fazeres que reconhecem a possibilidade da morte e da despedida, pode ser uma estratégia favorável ao enfrentamento desta realidade. O cuidador, diante do enfrentamento da doença juntamente com a pessoa sob seus cuidados buscam forças físicas e emocionais para conseguir lidar com as dificuldades, sendo que o primeiro evita compartilhá-las com o doente, mesmo que os momentos de fraqueza, de angústia e tristeza sejam inevitáveis. Relações entre espiritualidade e o significado ocupacional para o cuidar foram  identificadas, sendo representada como  sustento para o corpo e a alma ou como obediência a uma doutrina, apotando que as questões religiosas e espirituais propiciam confiança, esperança e fortalecem a fé.
Mujeres, derecho a la ciudad y desarrollo local

Las mujeres de las favelas han asumido el lugar de protagonistas en la lucha por los derechos sociales, con lo que se trasladan los valores fijos y consensuados de la estructura histórica heterocisnormativa y sexista a una verdadera revolución social que conjuga el género y la ciudad. Este estudio aborda los significados y los sentidos de la pobreza, desde la experiencia en las ocupaciones cotidianas de las mujeres habitantes de las favelas de Río de Janeiro, Brasil. Por lo tanto, se utilizan narrativas orales para comprender sus trayectorias y extraer categorías para reflexionar sobre los significados de la pobreza que prevalecen en acciones relacionadas con el desarrollo local y el derecho a la ciudad. Es una investigación exploratoria, con enfoque cualitativo, esto con el uso de la técnica de las “redes de referencia” para realizar las entrevistas con un guion semiestructurado; participan 4 mujeres residentes en el Complexo do Alemão, Río de Janeiro. Los significados de pobreza producidos en las narrativas de estas mujeres denuncian la ausencia de derechos sociales y políticas públicas locales, así como la necesidad de priorizar un valor positivo del lugar como espacio de lucha, resistencia y participación social. Es importante entender cómo estas mujeres producen tales significados y sentidos, todo por medio del análisis del contexto histórico y cultural del surgimiento y la expansión de las favelas, con un debate de los efectos del estigma social como barrera para el reconocimiento de estos territorios como centros de producción creativa, y expresión cultural y subjetiva.
