Modulating surface plasmon resonance response by an external electromagnetic wave
Authors: Joshi Ashutosh , Kumar Amrit , V Manjuladevi , Gupta R. K. 
Published: May 2021

Abstract
We fabricated a highly sensitive layered structure of organic molecules and studied the influence of polarization of the external electromagnetic (EM) wave on the surface plasmon resonance response from the layered structure. The layered structure was formed by depositing a self-assembled monolayer (SAM) of mercaptoundecanoic acid (MUA) followed by a single layer of Langmuir-Schaefer (LS) film of traditional calamitic liquid crystal molecule, 4

-octyl-4-biphenylcarbonitrile (8CB). The SAM of MUA was found to be non-responsive towards the change in resonance angle (RA) of surface plasmon resonance (SPR) due to the change in polarization of the external EM wave. However, such layer provides a soft-surface platform for the single layer of 8CB molecules which gets perturbed locally due to the incidence of the external EM wave. We obtained an oscillatory modulation of the change in RA due to the change in polarization angle of the EM wave with respect to the plane of incidence. The magnitude of sensitivity was found to be ∼4 milli°/° angle of polarization of the external EM wave. This study strongly suggests that sensitivity of a SPR-based sensor can be controlled by altering the linear state of polarization of the incident external EM wave.
Waiting for AIDS in Kuwait
Authors: Goffman Laura Frances 
Published: May 2021

Abstract
The HIV/AIDS pandemic evoked anxieties that were tied to Kuwait’s particular histories of gendered citizenship and dislocations of globalized labor. In Kuwait, to the best of our knowledge, HIV/AIDS has not reached epidemic levels. But in the midst of global discussions of HIV/AIDS in the late 1980s and early 1990s, anxiety surrounding Kuwait’s integration into transnational networks of travel and tourism brought tensions over gender roles, citizenship, sexuality, and infidelity to the forefront of public discourse. Drawing on local Arabic-language newspapers, public health campaign material, and state-sponsored publications on Islamic interpretations of HIV/AIDS, this article examines the significance of AIDS in a region where reactions to the pandemic centered on the process of constructing a potential medical event. Citizens and noncitizen residents of Kuwait articulated these anxieties in the context of waiting—waiting to be infected, waiting for a national outbreak, waiting in quarantine, and, for noncitizens who tested positive for HIV, waiting to be deported. By the mid-1990s, this process of anticipating and taking concrete legal measures to prevent a future epidemic resulted in the medicalization of social and political patterns of gender inequality, nativism, and differential citizenship.

Introducton: Chemotherapy is an important therapy in the treatment of cancer. Nausea, vomiting and worsening quality are some adverse effects of chemotherapy. Aromatherapy is an ancient technique that uses essential oils for physical and psychological/emotional improvement and is able to reduce the symptoms of chemotherapy and can be an excellent complementary technique.Objective: The aim of this systematic review was to determine the effects of aromatherapy on the adverse effects of chemotherapy in patients diagnosed with cancer. Methods: A search in three database PubMed, EMBASE and SCOPUS. Five studies that analyzed the use of aromatherapy to evaluate the reduction of the adverse effects of chemotherapy in a cancer patient, published only in English were included. Two reviewers, which independently examined titles and abstracts, identified records through database search and reference screening and irrelevant studies were excluded based in eligibility criteria. Relevant full texts were analyzed for eligibility, and all selected studies were included in this systematic review. Results: Five studies were included in this systematic review. This review suggests that aromatherapy reduces nausea, frequency of vomiting and improves quality of sleep. Conclusion: Aromatherapy is an effective technique to reduce nausea, the frequency of vomiting and improves the quality of sleep of patients diagnosed with cancer and undergoing chemotherapy. However, more randomized clinical trials with a good methodological quality are necessary to confirm the preliminary findings of this systematic review.
Formação de educadores de turmas multisseriadas: a narrativa como dispositivo formativo
Authors: Pena Selma Costa , De Oliveira Douglas Almeida 
Published: May 2021

Resultado de processo formativo do Programa Escola da Terra, o texto analisa uma prática de formação continuada, com professores/as, coordenadores/as pedagógicos e tutores/as de turmas multisseriadas, do município de Santarém, oeste do estado do Pará. A narrativa como dispositivo formativo foi elemento metodológico de construção de dados, permitindo recuperar e reconstruir os processos formativos dos professores, por vezes silenciados ou pouco considerados nos processos de pesquisas e de formação docente. Os resultados dessa prática formativa apresentam o abandono histórico a que vem sendo submetida a educação do campo no estado do Pará, convergindo para o já demonstrado nas legislações educacionais e na própria concepção de educação do campo. Conclui-se que a formação continuada implementada pelo Programa Escola da Terra apresentou outra forma de ver e de pensar o trabalho docente, a partir de suas narrativas, da discussão realizada com seus pares, das leituras realizadas e das sínteses construídas coletivamente.
Abecedário da inclusão: entrecruzando memória e formação docente
Authors: Fonseca Michele Pereira de Souza da , Leme Erika Souza 
Published: May 2021

O presente artigo tem como objetivo apresentar a análise das memórias de experiências excludentes dos professores/as, como elemento formativo, desenvolvido no Curso de pós-graduação em Educação Física escolar na perspectiva inclusiva. Este estudo é parte de uma pesquisa, cujo eixo central busca compreender os processos de inclusão/exclusão na formação/ação de professores de Educação Física. Neste artigo, apresentamos o Abecedário da Inclusão estruturado em pressupostos teórico-metodológicos que confrontam as bases sociais que forjam cotidianamente a exclusão. Trata-se de uma pesquisa qualitativa, contando com 19 docentes em formação continuada, que consentiram em rememorar suas experiências passadas na fase de escolarização. Os principais resultados apontaram a necessidade de se elaborar as “marcas" das exclusões vividas no passado para que se possa admitir um porvir sem a reprodução de estereótipos, rótulos e preconceitos, dando força, sentido e materialidade em um fazer político-pedagógico que se identifica e se relaciona com os valores humanitários da inclusão.
As oficinas de integração como prática pedagógica em tempos de incerteza e crise
Authors: Spacek Iuri Kieslarck , Silva Vitor Gomes da , Pasqualli Roberta 
Published: May 2021

A forma de organização curricular escolar vem, historicamente, produzindo a fragmentação do conhecimento sobre os objetos. Nesse sentido, as perspectivas de educação que se pautam em currículos integrados tem se demonstrado espaços privilegiados para o estudo e análise dos objetos enquanto síntese de múltiplas determinações, tornando-se alternativas pedagógicas em tempos de incerteza e crise. Sendo assim, este artigo tem como objetivo discutir as concepção de integração curricular apresentadas pelos estudantes de um Curso de Ensino Técnico em Informática Integrado ao Ensino Médio (CTIIEM) a partir da materialização da prática pedagógica na unidade curricular (UC) de Oficina de Integração (OI). A OI compõe um núcleo comum de UC com carga horária específica de preparação, aplicação, síntese e avaliação coletiva do processo pedagógico. Metodologicamente, trata-se de uma pesquisa exploratória e descritiva, de abordagem qualitativa e dialética, caracterizada como caso de estudo. Foi realizada por meio de pesquisa documental, teórica e análise de dados empíricos coletados com 120 estudantes. Como resultados, destacam-se duas categorias de análise: (a) a integração curricular como análise de um tema a partir de conhecimentos científicos distintos e, (b) a integração a partir de processos metodológicos diversificados colocando o estudante como sujeito do processo. Como resultados da pesquisa, considera-se que as duas categorias se conectam e expressam movimentos simultâneos de assimilação ativa dos conhecimentos por meio das Oficinas de Integração (OIs) já que, para os estudantes, as propostas tradicionais de ensino parecem como algo totalmente apartado de sua vida, algo com o qual ele não se identifica.

Authors: Thalukder Imran , Torofdar Halima , Collard Mechelle 
Published: May 2021

Drinking milk-like fluids made from plant-based materials, such as soya, nuts and peas, is an increasing trend within the population, and regular consumption of these non-dairy alternatives may increase the risk of developing caries. This article focuses on current research relating to caries risk and consumption of milk-like products, and also investigates the sugar content of milk alternatives available in the UK.CPD/Clinical Relevance: Frequent sugar attacks causes caries. Dentists need to be aware of milk and milk alternatives for some may contribute to the development of caries, and this should form part of their caries risk assessment.
Radiosurgery: A Forgotten Tool?
Authors: Brown Timothy , Donachie Martin 
Published: May 2021

Radiosurgery allows precise tissue cutting with simultaneous haemostasis, providing a clearer surgical field. Variation in waveform, power settings and handpiece tip shape allow for a wide variety of clinical applications, making it one of the most versatile pieces of surgical equipment in the dentist's arsenal. However, it is one of the most underused, and probably misunderstood, areas of surgery in dentistry. This may be due to conflicting literature concerning healing, overshadowing of the value of the technique by interest in dental lasers, misuse of terminology and a general lack of knowledge regarding the science underpinning its action.CPD/Clinical Relevance: This article aims to outline the mode of action, adjustable parameters and considerations for the safe use of radiosurgery alongside clinical examples of its applications.

Published: May 2021

Background
HIV management remains concerning and even more challenging in the frame of comorbidities like malnutrition that favors disease progression and mortality in resource-limited settings (RLS).

Objective
To describe the nutritional parameters of antiretroviral therapy (ART) recipients (without nutritional support) with respect to CD4 count and virological failure.

Methods
A cross-sectional study was conducted from October to December 2018 among 146 consenting participants enrolled in two health facilities of the East-Region of Cameroon. Socio-demographic data, basic clinical information and treatment history were collected; blood samples were collected by venipuncture for laboratory analysis (HIV-1 viral load, CD4 Tcells measurement and biochemical analysis) performed at the “Chantal Biya” International Reference Center”, Yaounde, Cameroon. The nutritional profile was assessed by using anthropometric and biochemical parameters. Data were analyzed using Excel 2016, Graph pad prism version 6; Spearman correlation and Kruskal-Wallis test were used; with p<0.05 considered statistically significant.

Results
Median [IQR] age was 42 [33–51] years, 76.0% (111/146) were female and median [IQR] duration on ART was 54 [28–86] months. Of these participants, 11.6% (17/146) were underweight based on the body mass index and 4.7% (7/146) were at the stage of advanced weight loss. According to immunovirological responses, 44.5% (65/146) were immunocompromised (CD4<500 cell/μl) and 75.3% (110/146) had an undetectable viremia (<40 copies/mL). CD4 count inversely correlated with total protein concentration (r = -0.18, p = 0.005**). Viremia was inversely correlated with albumin (r = -0.21; p = 0.047*), nutritional risk index (r = -0.28; p = 0.013*), total cholesterol (r = -0.27; p = 0.007**), and positively correlated with total protein (r = 0.27; p<0.001**) concentrations.

Conclusion
In this RLS, with patients having about five years of ART-experience, malnutrition appears to be driven mainly by a poor BMI, indicating that about one of ten patients falls within this severe condition. However, the largely normal nutritional profiles should be interpreted with caution, considering local realities and food support programs in place. The present outcomes highlight the need for monitoring nutritional status of people receiving ART in RLS, toward the design of optimal food interventions.

Published: May 2021

Background
Guinea has a high prevalence of female genital mutilation (FGM) (95%) and it is a major concern affecting the health and the welfare of women and girls. Population-based surveys suggest that health care providers are implicated in carrying out the practice (medicalization). To understand the attitudes of health care providers related to FGM and its medicalization as well as the potential role of the health sector in addressing this practice, a study was conducted in Guinea to inform the development of an intervention for the health sector to prevent and respond to this harmful practice.

Methodology
Formative research was conducted using a mixed-methods approach, including qualitative in-depth interviews with health care providers and other key informants as well as questionnaires with 150 health care providers. Data collection was carried out in the provinces of Faranah and Labé and in the capital, Conakry.

Results
The majority of health care providers participating in this study were opposed to FGM and its medicalization. Survey data showed that 94% believed that it was a serious problem; 89% felt that it violated the rights of girls and women and 81% supported criminalization. However, within the health sector, there is no enforcement or accountability to the national law banning the practice. Despite opposition to the practice, many (38%) felt that FGM limited promiscuity and 7% believed that it was a good practice.

Conclusion
Health care providers could have an important role in communicating with patients and passing on prevention messages that can contribute to the abandonment of the practice. Understanding their beliefs is a key step in developing these approaches.
A fast MR-thermometry method for quantitative assessment of temperature increase near an implanted wire
Authors: Delcey Marylène , Bour Pierre , Ozenne Valéry , Ben Hassen Wadie , Quesson Bruno 
Published: May 2021

Purpose
To propose a MR-thermometry method and associated data processing technique to predict the maximal RF-induced temperature increase near an implanted wire for any other MRI sequence.

Methods
A dynamic single shot echo planar imaging sequence was implemented that interleaves acquisition of several slices every second and an energy deposition module with adjustable parameters. Temperature images were processed in real time and compared to invasive fiber-optic measurements to assess accuracy of the method. The standard deviation of temperature was measured in gel and in vivo in the human brain of a volunteer. Temperature increases were measured for different RF exposure levels in a phantom containing an inserted wire and then a MR-conditional pacemaker lead. These calibration data set were fitted to a semi-empirical model allowing estimation of temperature increase of other acquisition sequences.

Results
The precision of the measurement obtained after filtering with a 1.6x1.6 mm2 in plane resolution was 0.2°C in gel, as well as in the human brain. A high correspondence was observed with invasive temperature measurements during RF-induced heating (0.5°C RMSE for a 11.5°C temperature increase). Temperature rises of 32.4°C and 6.5°C were reached at the tip of a wire and of a pacemaker lead, respectively. After successful fitting of temperature curves of the calibration data set, temperature rise predicted by the model was in good agreement (around 5% difference) with measured temperature by a fiber optic probe, for three other MRI sequences.

Conclusion
This method proposes a rapid and reliable quantification of the temperature rise near an implanted wire. Calibration data set and resulting fitting coefficients can be used to estimate temperature increase for any MRI sequence as function of its power and duration.

BackgroundChronic kidney disease is commonly found in patients with aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR) and has marked impact in their prognosis. It has been shown however that TAVR may improve renal function by alleviating the hemodynamic barrier imposed by AS. Nevertheless, the predictors of and clinical consequences of renal function improvement are not well established.Our aim was to assess the predictors of improvement of renal function after TAVR.MethodsThe present work is an analysis of the Brazilian Registry of TAVR, a national non-randomized prospective study with 22 Brazilian centers. Patients with baseline renal dysfunction (estimated glomerular filtration rate [eGFR] < 60mL/min/1.73m2) were stratified according to renal function after TAVR: increase >10% in eGFR were classified as TAVR induced renal function improvement (TIRFI); decrease > 10% in eGFR were classified as acute kidney injury (AKI) and stable renal function (neither criteria).ResultsA total of 819 consecutive patients with symptomatic severe AS were included. Of these, baseline renal dysfunction (estimated glomerular filtration rate [eGFR] < 60mL/min/1.73m2) was present in 577 (70%) patients. Considering variance in renal function between baseline and at discharge after TAVR procedure, TIRFI was seen in 197 (34.1%) patients, AKI in 203 (35.2%), and stable renal function in 177 (30.7%).The independent predictors of TIRFI were: absence of coronary artery disease (OR: 0.69; 95% CI 0.48–0.98; P = 0.039) and lower baseline eGFR (OR: 0.98; 95% CI 0.97–1.00; P = 0.039). There was no significant difference in 30-day and 1-year all-cause mortality between patients with stable renal function or TIRFI. Nonetheless, individuals that had AKI after TAVR presented higher mortality compared with TIRFI and stable renal function groups (29.3% vs. 15.4% vs. 9.5%, respectively; p < 0.001).ConclusionsTIRFI was frequently found among baseline impaired renal function individuals but was not associated with improved 1-year outcomes.

Published: May 2021

Objective
Placental abruption is a significant obstetric complication that affects both maternal and neonatal mortality and morbidity. The present study examined the effect of maternal age on the incidence of placental abruption.

Methods
We used data of singleton pregnancies from the Japan Environment and Children’s Study, which was a prospective birth cohort study conducted between January 2011 and March 2014 across 15 regional centers in Japan. A multiple regression model was used to identify whether maternal age (<20 years, 20–24 years, 25–29 years, 30–34 years, and ≥35 years) is a risk factor for placental abruption. The analyses were conducted while considering the history of placental abruption, assisted reproductive technology, number of previous deliveries, smoking during pregnancy, body mass index before pregnancy, and chronic hypertension.

Results
A total of 94,410 Japanese women (93,994 without placental abruption and 416 with placental abruption) were recruited. Herein, 764, 8421, 25915, 33517, and 25793 women were aged <20 years, 20–24 years, 25–29 years, 30–34 years, and ≥35 years, respectively. Besides advanced maternal age (≥35 years; adjusted odds ratio: 1.7, 95% confidence interval: 1.1–2.5), teenage pregnancy was also a risk factor for placental abruption (adjusted odds ratio: 2.8, 95% confidence interval: 1.2–6.5) when the maternal age of 20–24 years was set as a reference.

Conclusions
In the Japanese general population, besides advanced maternal age, teenage pregnancy was associated with placental abruption. Recently, the mean maternal age has been changing in Japan. Therefore, it is important for obstetric care providers to provide proper counseling to young women based on up-to-date evidence.
