Authors: Gonzalez Rocio , Custodio Jesica Brenda , Zalazar-Jaime Mauricio Federico , Medrano Leonardo Adrian
Published: October 2021

INTRODUCCIÓN. Una de las herramientas más utilizadas para la evaluación de la inteligencia emocional autopercibida (IEA) es el Trait Meta-Mood Scale (TMMS). Sin embargo, existen escasos estudios que den cuenta de cómo funciona en estudiantes universitarios argentinos. Sumado a ello, recientemente se ha propuesto una revisión de la estructura factorial del TMMS-24, por lo que se requiere de nuevas investigaciones a los fines de examinar cuál es la estructura factorial que representa más adecuadamente a la IEA. El objetivo del presente estudio fue analizar la estructura factorial del TMMS-24 (probando el modelo bifactor y utilizando coeficientes adicionales), como así también su validez y confiabilidad, con el fin de aportar evidencias que garanticen la calidad de la medida en su adaptación al contexto local para su aplicación a estudiantes universitarios de Buenos Aires, Argentina. MÉTODO. La muestra estuvo comprendida por 374 estudiantes, quienes respondieron un cuestionario sociodemográfico, el TMMS-24, y las versiones argentinas del Cuestionario de regulación emocional y el Inventario de cociente emocional. RESULTADOS. El análisis factorial confirmatorio dio cuenta de un adecuado ajuste del modelo a los datos al modelo oblicuo (tres factores correlacionados con sus respectivos indicadores: atención, claridad y reparación; X2 = 803.354, GL = 249, CFI .9384, TLI .931, RMSEA [90% IC] = .0778; [.071, .083], WRMR 1.5273). Si bien el modelo bifactor evidenció índices de ajuste satisfactorios, los indicadores adicionales no fueron adecuados. La consistencia interna fue adecuada para cada subescala (atención emocional ω = .90; claridad emocional ω = .90; reparación emocional ω = .88). Se encontraron diferencias según sexo y edad para ciertas subescalas y correlaciones esperadas con las subescalas del ERQ-A y del EQ-i. DISCUSIÓN. El TMMS-24 mostró propiedades psicométricas adecuadas para la medición de IEA en población universitaria de Buenos Aires.

Published: October 2021

Carbamazepine (CBZ) is a commonly used drug for the treatment of
epilepsy. Due to the narrow effective range, CBZ concentration was
usually monitored with blood draw from patients. Frequent blood draw
is inconvenient and causes physical and psychological pain. Therefore,
highly-sensitive, rapid, label-free, and non-invasive drug detection
methods can be alternatives to bring a relief. In this work, we have
proposed a method for the non-invasive detection of CBZ using
surface-enhanced Raman spectroscopy (SERS). Gold-silver core-shell
nanomaterial substrates were prepared and optimized. Salivary CBZ
concentration was measured with SERS as a non-invasive alternative to
blood draw. The results showed that there was a linear relationship
between SERS response and CBZ concentration in the entire measured
range of 10−1 ∼ 10−8 mol/L.
The detection limit of this method was 1.26 ×
10−9 mol/L. Satisfactory repeatability and stability
were also demonstrated. Due to its high sensitivity and ease of
operation, the proposed method can serve as an alternative to blood
draw for non-invasively monitoring CBZ concentration. It also has
great potentials in many other applications of biomedical
sciences.

Simultaneous spectral and polarimetric imaging enables versatile detection and multimodal characterization of targets of interest. Current architectures incorporate a 2×2 pixel arrangement to acquire the full linear polarimetric information causing spatial sampling artifacts. Additionally, they suffer from limited spectral selectivity and high color crosstalk. Here, we demonstrate a bio-inspired spectral and polarization sensor structure based on integrating semitransparent polarization-sensitive organic photovoltaics (P-OPVs) and liquid crystal polymer (LCP) retarders in a tandem configuration. Color tuning is realized by leveraging the dynamic chromatic retardation control of LCP films, while polarization sensitivity is realized by exploiting the flexible anisotropic properties of P-OPVs. The structure is marked by its ultra-thin design and its ability to detect spectral and polarimetric contents along the same optical axis, thereby overcoming the inherent limitations associated with conventional division-of-focal plane sensors.

Published: October 2021

GHz pulsed thulium-doped fiber laser with stabilized repetition rate can enable a wide range of applications. By employing regenerative mode-locking and cavity stabilization technique, we have for the first time demonstrated a 10 GHz polarization-maintaining thulium-doped fiber laser, which has a long-term repetition-rate stabilization and picosecond timing-jitter. In our experiment, a RF circuitry is designed to extract the 10 GHz longitudinal clock signal so that stable regenerative mode-locking is achieved. A piezo actuator-based phase-lock-loop is used to lock the regeneratively mode-locked pulses to a local reference synthesizer. The regeneratively mode-locked pulses with picosecond pulse width exhibit a high super-mode suppression ratio of 60 dB. In addition, the repetition rate of the laser shows good long-term stability with a variation of 8 Hz in 8 hours, corresponding to a cavity free spectral range fluctuation of less than 16 mHz. Meanwhile, the Allan deviation of the stabilized 10 GHz regeneratively mode-locked pulses is measured to be as low as 2 × 10−12 over 1000 s average time, which is only limited by the stability of the reference synthesizer. Such an ultra-stable 10 GHz pulsed thulium fiber laser may find potential application in 2 µm optical communication, material processing and spectroscopy.
Design approach for photonic quasicrystals to enable multiple nonlinear interactions
Authors: Tsvetkov Dmitrii , Gao Jiannan , Frantz Jesse , Litchinitser Natalia M.
Published: October 2021

Photonic quasicrystals are poised to transform the field of nonlinear light-matter interactions due to their ability to support an unlimited number of combinations of wavevectors in their reciprocal lattices. Such greatly enhanced flexibility enabled by k-space engineering makes photonic quasicrystals a promising platform for novel approaches to multi-wavelength conversion, supercontinuum generation, and development of classical and quantum optical sources. Here, we develop a new design method for nonlinear photonic quasicrystals, consisting of a combination of one nonlinear material and one linear material that can simultaneously fulfill phase-matching conditions for a desired number of nonlinear optical interactions as long as the frequencies of the interacting waves are outside of the bandgaps of the quasicrystal structure. Our approach provides enhanced design flexibility, enabling new pathways to designing compact, integrated nonlinear photonic devices and systems on a chip.

Published: October 2021

The linear polarized (LP) mode multiplexer based on the inverse designed multi-plane light conversion (MPLC) has the advantages of low insertion loss and low mode crosstalk. However, the multiplexer also requires the fabrication and alignment accuracy in experiments, which have not been systematically analyzed. Here, we perform the error tolerance analysis of the MPLC and summarize the design rules for the LP mode multiplexer/demultiplexer. The error tolerances in the fabrication process and experimental demonstration are greatly released with proper parameters of the input/output optical beam waist, the pitch of optical beam array, and the propagation distances between the phase plane. To proof this design rule, we experimentally demonstrate the LP mode multiplexer generating LP01, LP11a, LP11b, LP21 modes and coupling to the few mode fiber, with the insertion loss lower than -5 dB. The LP modes are demultiplexed by MPLC, with the crosstalk of different mode groups lower than -10 dB. LP modes carrying 10 Gbit/s on-off keying signals transmit in a 5 km few mode fiber. The measured bit error rates (BER) curves of the LP01, LP11a, LP21 modes have the power penalties lower than 12 dB.
Spherical wavefront measurement on modified cyclic radial shearing interferometry
Authors: Bian Dian , Joo Ki-Nam , Lu Yang , Yu Liandong
Published: October 2021

We propose a radial shearing interferometric approach to measure spherical wavefronts as both of the reflective and transmissive optical configurations. The modified cyclic radial shearing interferometer uses a single lens in the optical layout, which can conveniently adjust the radial shearing ratio between two shearing spherical wavefronts, and the use of a polarization camera enables to reconstruct the wavefront by a single image. The wavefront mapped onto the camera plane can be identified and quantified throughout an optimized wavefront reconstruction algorithm. In the experiments, plano-convex lenses and concave mirrors were used to generate spherical wavefronts, and the proposed system was able to reconstruct the surface figures after system characterization and calibration. Further investigations were performed to evaluate the system measurement accuracy by the radius of curvature comparison with design value and a commercial Shack-Hartmann wavefront sensor.
Online stereo vision measurement based on correction of sensor structural parameters
Authors: Shi Bowen , Liu Zhen , Zhang Guangjun
Published: October 2021

Vibration can easily affect the structure of long baseline binocular vision sensors, resulting in changes in the external parameters of the binocular calibration model and the failure of measurement method. This paper presents an online stereo vision measurement based on correction of sensor structural parameters. The flexible structure model based on calibration model and iterative gradient descent nonlinear optimization model based on 3D redundant information are established. The optimal estimation of external parameters and object position measurement are realized according to multi-information constraints. Experiments show that this method can effectively solve the measurement failure caused by vibration in stereo vision measurement.
Whispering gallery mode resonance contribution in photonic nanojet simulation
Authors: Zihan Yi , Sylvain Lecler
Published: October 2021

A photonic nanojet is a highly localized electromagnetic propagative beam in the shadow side of a dielectric micro-particle. This concept was introduced in a famous paper by Chen et al. in 2004. Since then, this paper has inspired numerous original developments all over the world. Several years later, we point out that whispering gallery mode (WGM) resonances, not always brought out by FDTD simulations, can coexist in addition to the photonic jet. Such WGM resonances drastically change the distribution of the electric field. Through subsequent simulations, we show how these WGM resonances are highly sensitive to parameter changes. Particle diameter change smaller than 1 nm is enough to make them disappear. This may explain why sometimes they are not observed by FDTD simulations despite high resolution spatial mesh.

Глобализация анализа моделей размещения частиц по ячейкам
Authors: Энатская Наталия Юрьевна , Enatskaya Nataliya Yur'evna
Published: October 2021

Рассматривается общий подход к доасимптотическому анализу схем с разными качествами во всех сочетаниях по их различимости составляющих их элементов (ячеек и частиц).
Для этого в каждой группе таких схем с общими ограничениями вместо непосредственного их изучения на основе учета специфики каждой схемы предлагается некоторый общий набор алгоритмических процедур пересчета результатов их доасимптотического анализа в схеме начиная со схемы с наибольшей дифференциацией их исходов последовательно для остальных схем группы с различиями в качестве одного элемента.
Анализ каждой схемы проводится по традиционным и по ряду следующих новых направлений:
построение случайного процесса формирования и нумерованного бесповторного перечисления исходов схемы в порядке их получения; нахождение числа исходов схемы; решение задачи нумерации для исходов схемы,
состоящей в установлении взаимно однозначного соответствия между их видами и номерами; задание их вероятностного распределения и моделирования исходов схемы с этим вероятностным распределением.
В частности, отдельно изучаются случаи групп схем без ограничений размещения частиц и с ограничением (не более одной частицы в ячейке), приводящие к некоторым известным аналитическим результатам.
При любых ограничениях в рассматриваемой группе схем их анализ проводится путем реализации алгоритмических процедур последовательного преобразования результатов анализа одной схемы группы для другой.
Объединения в такие пары схем производятся по признаку различия качества одного их элемента.
Второе интегральное обобщение инварианта Крокко для 3D-течений за отошедшим головным скачком
Authors: Сизых Григорий Борисович , Sizykh Grigory Borisovich
Published: October 2021

Исследуются стационарные течения идеального газа за отошедшим головным скачком в общем 3D-случае. Известный интегральный инвариант (В.Н. Голубкин, Г.Б. Сизых, 2019), обобщающий осесимметричный инвариант
(Л. Крокко, 1937) на несимметричные течения, есть криволинейный интеграл по замкнутой вихревой линии (такие линии лежат на изоэнтропийных поверхностях) от давления, деленного на завихренность. Этот интеграл принимает одно и то же значение на всех (замкнутых) вихревых линиях, лежащих на одной изоэнтропийной поверхности.
Он был получен после обнаружения факта замкнутости вихревых линий в течении за скачком в общем 3D-случае. Недавно было найдено еще одно семейство замкнутых линий за скачком, лежащих на изоэнтропийных поверхностях (Г.Б. Сизых, 2020). Это векторные линии a - векторного произведения скорости газа и градиента энтропийной функции. В общем 3D-случае эти линии и вихревые линии не совпадают.
В представленном исследовании предпринимается попытка найти интегральный инвариант, связанный с замкнутыми векторными линиями a.
Без использования асимптотических, численных и других приближенных методов проводится анализ уравнений Эйлера для классической модели течения идеального совершенного газа с постоянными теплоемкостями.
Используется представление о воображаемых частицах, «переносящих» линии тока реального течения газа, основанное на критерии Гельмгольца-Зоравского.
Получен новый интегральный инвариант изоэнтропийных поверхностей.
Показано, что криволинейный интеграл по замкнутой векторной линии a, в котором подынтегральная функция есть давление, деленное на проекцию завихренности на направление a, принимает одинаковые значения для всех линий a, лежащих на одной изоэнтропийной поверхности.
Этот инвариант, как и другой ранее известный интегральный инвариант (В.Н. Голубкин, Г.Б. Сизых, 2019) в частном случае незакрученных осесимметричных течений совпадает с неинтегральным инвариантом Л. Крокко и обобщает его на общий пространственный случай.

Authors: Зотеев Владимир Евгеньевич , Zoteev Vladimir Eugenievich
Published: October 2021

Стремление к уменьшению массы машин и конструкций при улучшении их качества, а также к наиболее полному использованию механических свойств материалов требует постоянного совершенствования и развития известных методов расчета и анализа напряженно-деформированного состояния материалов в условиях ползучести.
В статье предлагается численный метод оценивания характеристик третьей стадии неизотермической ползучести по совокупности диаграмм ползучести, построенных при обработке результатов испытаний для различных значений номинального напряжения и температур.
В основе метода лежат нелинейные регрессионные модели, среднеквадратичные оценки параметров которых находятся посредством линеаризации, в том числе на основе разностных уравнений, описывающих результаты наблюдений.
Предлагаемый численный метод может быть также использован для оценки параметров третьей стадии ползучести, когда результаты эксперимента в форме совокупности диаграмм испытаний представлены только для одной температуры.
Приведены результаты апробации разработанного численного метода при обработки результатов эксперимента в форме диаграмм ползучести сплава 09Г2С при различных температурах.
Достоверность и эффективность представленных в работе алгоритмов вычислений и методов нелинейного оценивания подтверждаются результатами численно-аналитических исследований и построенными на основе экспериментальных данных математическими моделями третьей стадии неизотермической ползучести.

Challenges of the International Baccalaureate Middle Years Programme: Insights for school leaders and policy makers
Authors: Dickson Anisah , Perry Laura , Ledger Susan
Published: October 2021

Policy makers in the US and several other countries are recommending that more schools offer an International Baccalaureate (IB) programme. However, little is known about the challenges that IB programmes present for teaching and learning particularly those meeting national curriculum.  In this study, we examined the challenges of the IB’s Middle Years Programme (MYP), the least understood and researched of the IB programmes. Using a qualitative case study design, we conducted in-depth and semi-structured interviews with school leaders (n=7) and teachers (n=10) from three schools in Australia that previously offered the MYP. We used thematic analysis to generate the findings and the IB’s Standards and Practice framework to organize the reporting of findings. Participants shared perceived challenges related to philosophical factors, organizational dilemmas and complexities with integrating the MYP with Australia’s national curriculum. Understanding the organizational and leadership challenges that schools may face when offering the MYP can help policy makers promote the necessary conditions for successful program implementation.

The definition of pH, its measurement and standard buffers, is well developed in aqueous solutions. Its definition in solvents other than water has been elaborated for a couple of solvents and their mixtures with water. However, the definition of a universal pH scale spanning all solvents and phases, not to mention standard procedures of measurement, is still a largely uncharted territory. UnipHied is a European collaboration and has the goal of putting the theoretical concept of an earlier introduced (2010) unified pHabs scale on a metrologically well-founded basis into practice. The pHabs scale enables the comparability of acidity between different phases. This article draws the connection of the concepts of unified acidity and secondary pH measurement.

Published: October 2021

Recently developed probes for extracellular electrophysiological recordings have large numbers of electrodes on long linear shanks. Linear electrode arrays, such as Neuropixels probes, have hundreds of recording electrodes distributed over linear shanks that span several millimeters. Because of the length of the probes, linear probe recordings in rodents usually cover multiple brain areas. Typical studies collate recordings across several recording sessions and animals. Neurons recorded in different sessions and animals thus have to be aligned to each other and to a standardized brain coordinate system. Here, we evaluate two typical workflows for localization of individual electrodes in standardized coordinates. These workflows rely on imaging brains with fluorescent probe tracks and warping 3D image stacks to standardized brain atlases. One workflow is based on tissue clearing and selective plane illumination microscopy (SPIM), whereas the other workflow is based on serial block-face two-photon (SBF2P) microscopy. In both cases electrophysiological features are then used to anchor particular electrodes along the reconstructed tracks to specific locations in the brain atlas and therefore to specific brain structures. We performed groundtruth experiments, in which motor cortex outputs are labeled with ChR2 and a fluorescence protein. Light-evoked electrical activity and fluorescence can be independently localized. Recordings from brain regions targeted by the motor cortex reveal better than 0.1-mm accuracy for electrode localization, independent of workflow used.
GIS Modelling of the Distribution of Terrestrial Tortoise Species: Testudo graeca and Testudo hermanni (Testudines, Testudinidae) of Eastern Europe in the Context of Climate Change
Authors: Nekrasova O. , Tytar V. , Pupins M. , Čeirāns A. , Skute A.
Published: October 2021

The study of the distribution of protected animal species in Europe is especially relevant in a changing climate. Therefore, in this work, we tried to solve the problem of the possibility of habitation of tortoises Testudo graeca Linnaeus, 1758 and Testudo hermanni Gmelin, 1789 in Eastern Europe by using species distribution models (SDMs). We used bioclimatic variables from the CliMond dataset (18 uncorrelated variables of 35) and 19 Paleoclim variables of the “early-Holocene” and “mid-Holocene”. Packages Maxent and 'ntbox' were employed. In addition to our data, we used findings listed in the GBIF databases: 1,935 points for T. graeca and 991 points for T. hermanni. It has been shown that subspecies of tortoises differ in the characteristics of the ecological niche. In addition to direct anthropogenic influences, the limiting factor is the “Mean temperature of coldest quarter” (bio11) for both species. Moreover, T. graeca is less demanding and can tolerate both frost and higher temperatures during drier periods than T. hermanni. Modeling found that in the future it is possible for these species will expand in a north-eastern direction, where potentially suitable habitats will appear: by 2090 in the South of Ukraine (Odessa region, Crimea) and East Ukraine (floodplain of the Siversky Donets River of the Don basin).

Maritime relations between Kollam and the portuguese – A review
Authors: Adabiya H.
Published: October 2021

India has an ancient and glorious maritime history and tradition in which the Kerala Coast occupied a position of pride from very early days. The coast of Kerala has a rich and long maritime heritage. The geographical situations and economic resources made this country a great trading and maritime power. Kollam is an important trading town with a well set up Port. It had trading relation with Chinese, Arabs and other oriental world. Kollam is an old sea Port town on the Arabian coast had a sustained commercial reputation from the days of Phoenicians and the Romans. The place was famous for trade in cotton, pepper, ginger, cardamom and other articles of merchandize. Moreover plenty of fish, rice, bananas, fruits and pulses available there.The Portuguese were the first Europeans to establish a trading centre at Kollam. The present paper seeks to analyze the maritime intercourse between Kollam and the Portuguese. The arrival of Vasco Da Gama at Calicut in1498 brought Kerala into the arena of international politics. Thangasseri in Kollam is one of the earliest settlements of the Portuguese. Certainly, the impact of the early colonizers on Thangasseri is very deep. It brought about far reaching changes in the socio-cultural and religious map of the city. It is true that the arrival of Portuguese made many socio-economic changes in Kerala. The Portuguese policy of establishing their supremacy cannot be confined to trade alone.

Published: October 2021

Abstract Background: Spasticity, fatigue, muscle weakness and changes in gait are some of the main motor symptoms of Multiple Sclerosis (MS). These changes can interfere with the patients’ quality of life. Objective: To characterize the motor and quality of life symptoms in patients with relapsing-remitting Multiple Sclerosis at a specialized center. Methods: Fifty five patients at the Neuroimmunology Outpatient Clinic of the Hospital de Clínicas de Porto Alegre were evaluated for fatigue (Fatigue Severity Scale — FSS), walking ability (Functional Ambulation Categories — FAC), impact of MS on walking (Multiple Sclerosis Walking Scale-12 — MSWS-12), walking speed (10-Meter Walk Test — 10MWT and the Times 25-foot Walk test — T25FW), functional independence (Barthel Index — BI), functional mobility (Timed Up and Go — TUG), and quality of life (Multiple Sclerosis Impact Scale — MSIS-29). Results: The patients were mostly women (69.1%), with average age of 43.3 (±12.1) years old, with time since diagnosis of 8.2 (±5.3) years, and EDSS average of 4.3 (±1.3). On the BI, the mean was 96.6 (±5.7) points and 80% of the patients had FAC 5. At MSIS-29, patients had a higher average score on the psychological scale (19.5±26.7) than on the physical scale (10.2±23.6). Most patients (69.1%) presented fatigue. Conclusion: The patients had preserved functional independence and functional walking ability and presence of fatigue. There was minimal impact of MS on patients’ quality of life.

Objective: The aim of the present study was to identify the features of the right-to-left shunt (RLS) in patients with undetermined embolic ischemic stroke and compare them with those of patients with non-cardioembolic ischemic stroke. Methods: A retrospective study was conducted with 168 patients with stroke and RLS separated into the following two groups: the undetermined embolic stroke group (UES group) and non-cardioembolic stroke group (NCES group). All patients were assessed by transcranial Doppler to evaluate the presence and quantification of microembolic signals (MES) at rest and under Valsalva maneuver. Results: Of all patients evaluated in the current study, 96 were included in the UES group and 72 in the NCES group. In the UES group, 65 patients had RLS with ≥10 MES (67.7%), which was higher than that observed in the NCES group (51.4%, p=0.038). According to the moment of the cardiac cycle, 75 patients (78.1%) in the UES group had a positive test at rest compared to 42 (58.3%) in the NCES group (p=0.007). Conclusions: The current study demonstrated that almost 70% of patients with undetermined embolic stroke and PFO presented a large RLS and more than 75% had RLS at rest. These findings suggest that the size of the shunt should be taken into account when evaluating whether PFO could be a possible mechanism underlying cryptogenic stroke.

Published: October 2021

Resumo: O objetivo do artigo é analisar o debate ocorrido na Câmara dos Deputados sobre o Projeto de Lei 7.672/2010, que previa o direito das crianças e adolescentes de serem educados e cuidados sem o uso de castigos físicos ou tratamento cruel ou degradante, transformado na Lei Menino Bernardo (Lei 13.010/2014). No total, foram lidos e fichados no software estatístico Sphinx Lexica 68 discursos proferidos no plenário e 93 pronunciamentos realizados em comissões ou audiências. A análise do debate mostra que predominou uma posição favorável à proibição de castigos físicos, que as deputadas mulheres tiveram um papel relevante na comissão especial e na defesa do projeto no plenário e que houve diferenças importantes entre o debate na comissão especial e no plenário.

ABSTRACT: This study evaluated the Dolichopodidae abundance in different cover crop species. For this, the following species were used in treatments: Crotalaria (Crotalaria spectabilis), cowpea (Vigna unguiculata), sunflower (Helianthus annuus), castor bean (Ricinus communis) and buckwheat (Fagopyrum esculentum). The survey was carried out in a field during two seasons 2012/2013 (November/December to March) and 2013/2014 (October/November to February). The Dolichopodidae abundance were evaluated weekly using a sweep net and Moericke traps. In addition, the phytophagous abundance (Thysanoptera: Thripidae; Hemiptera: Aleyrodidae and Hemiptera: Aphididae) was quantified, to allow for an inference about density-dependence. In total, 13,987 long-legged flies (96.5% in Moericke traps) were captured, represented only by the species Condylostylus erectus Becker, 1922 (Diptera: Dolichopodidae). In general, the higher abundance of C. erectus was observed in buckwheat and cowpea. Regarding the phytophagous species, 48,371 individuals [Thripidae (77.5%), Aleyrodidae (20.2%), and Aphididae (2.5%)] were quantified and a clear correlation with the C. erectus population was not evidenced. Thus, these results suggested that buckwheat and cowpea make resources available to long-legged flies, as discussed in our research. Finally, the buckwheat and cowpea sowing are options to increase the abundance of C. erectus predator populations in agroecosystems.

Resumo O artigo analisa a configuração das relações público-privadas no sistema de saúde do Chile, no período de 2000 a 2018. As dimensões de análise abordaram a organização e a regulação, o financiamento e a prestação de serviços de saúde. Foram utilizadas como técnicas de pesquisa: revisão bibliográfica, análise de documentos e de dados secundários e entrevistas. Três principais achados foram observados. Na dimensão organizacional e regulatória observou-se escassez de mecanismos institucionais que atenuem a seleção de riscos e vinculação do acesso à capacidade de contribuição dos afiliados do subsistema privado. O modelo de financiamento adotado foi insuficiente para a manutenção do sistema público. Em relação à prestação, apesar da implementação de estratégias que sugerem avanços, a fragmentação do sistema e a compra de serviços privados mantêm a segmentação do sistema. No sistema de saúde chileno, o caráter das relações público-privadas nas dimensões analisadas reitera a segmentação entre grupos populacionais produzidos pela lógica de priorização dos mercados na saúde. As reformas implementadas no período de análise atenuaram os efeitos da segmentação, mas não foram capazes de produzir mudanças estruturais na configuração do sistema de saúde.

Resumo A Atenção Primária à Saúde (APS) é considerada imprescindível para a efetividade dos sistemas de saúde. O objetivo deste estudo foi avaliar a qualidade da assistência prestada na APS em um município de Pernambuco. Realizou-se um estudo exploratório através da escuta a 525 usuários utilizando questionários estruturados. A avaliação da qualidade considerou as dimensões: acessibilidade, assistência clínica, relação profissional-usuário, atividades comunitárias e estrutura. Os resultados apontam para um contexto de perpetuação das vulnerabilidades sociais e o desafio em alcançar um atendimento equitativo e universal. Os principais aspectos de insatisfação foram: dificuldade de acesso a consultas e exames especializados, tempo de espera para atendimento e possibilidade de apresentar reclamações. Por outro lado, os entrevistados apresentaram-se satisfeitos com o atendimento médico e de enfermagem, principalmente quanto ao respeito, privacidade, escuta e confidencialidade. Verificou-se que apesar dos profissionais de saúde se empenharem na prestação de um atendimento humanizado, foi evidente a fragmentação do cuidado na rede estudada, o que dificulta o seguimento adequado e oportuno ao paciente, refletindo negativamente na qualidade da assistência prestada.

Resumo O artigo apresenta o projeto De Nosso Território Sabemos Nós, em duas comunidades das cidades serranas fluminenses que sofreram o desastre de 2011, com o objetivo da criação de dispositivo para comunicação on-line, associado à cartografia social, buscando pôr em diálogo gestão e cidadãos de maneira permanente e dinâmica. O dispositivo permite que as necessidades locais sejam visíveis para deliberação de políticas públicas. A constituição das Comunidades Ampliadas de Pesquisa, composta por moradores e suas associações, participantes da gestão municipal e pesquisadores em regime de ecologia dos saberes, se realizaram através de oficinas cartográficas. A identificação das vulnerabilidades e potencialidades das comunidades, o aflorar das memórias e conhecimentos locais permitem o fortalecimento da resiliência comunitária. Dessa forma, a valorização da experiência na elaboração das cartografias sociais faz emergir a autoconsciência do grupo. O processo de mapeamento demonstrou o quanto os territórios são desconhecidos para a gestão municipal e até mesmo para seus moradores.

Resumo O objetivo deste artigo é apresentar uma análise dos resultados do Programa de Formação em Qualidade em Saúde e Segurança do Paciente (CQSSP) da Escola Nacional de Saúde Pública Sergio Arouca, da Fundação Oswaldo Cruz. Trata-se de uma abordagem quantitativa e qualitativa, transversal e descritiva, baseada no Modelo de Avaliação de Kirkpatrick. Os achados dimensionaram o êxito da proposta pedagógica do CQSSP com avaliação considerada positiva nos níveis de Reação, Aprendizagem, Comportamento e Resultados. A partir de análise da percepção de egressos, observou-se que 82% destes passaram a considerar plenamente a ocorrência de erro na prática do cuidado, 68% a incorporar os conhecimentos adquiridos à sua prática profissional, e 73% passaram a estudar e pesquisar temas relacionados à segurança do paciente. Inquérito captando o número de Núcleos de Segurança do Paciente ou instâncias equivalentes constituídos ou reformulados durante ou depois do CQSSP foi realizado. Avaliou-se, ainda, o grau de contribuição do curso na implementação dos protocolos e ações de Segurança do Paciente (SP) nos hospitais, refletindo, assim, a significativa contribuição do CQSSP para a segurança do paciente e qualidade do cuidado hospitalar.

Resumen La Agenda 2030, una estrategia de la Organización de las Naciones Unidas (ONU) para promover un desarrollo humano global y sostenible capaz de satisfacer necesidades sociales básicas, aún se encuentra en sus etapas iniciales en la mayoría de los países de América del Sur. La presente investigación tuvo como objetivo consultar a un grupo de expertos en salud sobre las posibilidades de Argentina de cumplir con la Agenda 2030, en especial las metas del ODS3-Salud y Bienestar-, a su vez que se les consultó sobre los obstáculos, desafíos y recomendaciones de políticas para cumplir con las metas. El cambio de gestión del gobierno en diciembre de 2019, y el surgimiento de la pandemia COVID19 en el presente año, amplió la investigación incorporando el análisis del actual Ministro de Salud de la Nación sobre la Agenda 2030, el estudio realizado y las perspectivas actuales en el periodo de la pandemia. Los resultados fueron analizados en perspectiva comparada con un estudio brasilero, y mostraron que la mayoría de los expertos coincide en el bajo potencial del país para cumplir con las metas de la Agenda 2030. Sin embargo en el análisis del nuevo Ministro de salud surgen “las paradojas de la pandemia” que refieren a la oportunidad de fortalecer el sistema sanitario producto de la pandemia COVID-19.

Published: October 2021

Resumo A pandemia de SARS-CoV-2 trouxe desafios relacionados à prevenção, proteção e cuidado. Estratégias de enfrentamento, como distanciamento social, medidas de proteção individual da população e trabalhadores, ampliação dos leitos de terapia intensiva, disponibilização de recursos humanos e equipamentos são ações necessárias. Não há, ainda, medicamentos específicos com eficácia e segurança que justifiquem sua utilização. O desafio imposto ao marco regulatório de medicamentos volta-se para o acesso tempestivo a medicamentos capazes de modificar o curso da doença e conduzir a melhores desfechos no tratamento, com segurança sanitária. Cabe às agências reguladoras a proteção da saúde com a atribuição de avaliar os reais benefícios e malefícios dos medicamentos nestas condições especificas. O artigo apresenta as ações das agências reguladoras e discute os desafios na implementação da política regulatória de medicamentos frente às exigências impostas pela pandemia de COVID-19. São abordadas, especialmente, estratégias de desenvolvimento de fármacos e estratégias regulatórias sobre a indicação de uso off label, do uso emergencial de medicamentos e das alternativas de uso extendido/compassivo, bem como da realização de ensaios clínicos e da avaliação da segurança e monitoramento de eventos adversos.

Published: October 2021

Abstract The manuscript discusses interfaces between academic and practical fields of Global Health and Planetary Health, shedding light on some critical perspectives of cumulative and synergistic causes of global crises, and effects on health and food security, on human rights, on migration, and on environment. Concepts of Global Health and Planetary Health and the path for the Sustainable Development Goals -SDG in the context of the Syndemy of Global Crisis, in particular the COVID-19 pandemic, are presented. COVID-19 lessons highlight challenges of infectious diseases and pandemics of the crisis of food insecurity, and of climate emergency. The manuscript advocates for an innovative approach that simultaneously broader awareness of the interconnected problems and of their complex causes and calls for emancipatory knowledge to face urgent challenges for a transdisciplinary research agenda aiming to tackle enormous planetary problems brought by the Anthropocene. It calls for practical solutions, with examples of some nature-based. It highlights the need of a collective reflection on a viable path to promote changes for a more sustainable, equitable, and adaptive future, bridging gaps from Global and Planetary Health.
