Authors: Siddique Farhana , M Saranya , M Saranya Christabell , S Prema
Published: October 2020

The tongue is a muscular hydrostat which is a part of oral cavity. The interaction of tongue with palate is essential for articulation of speech and swallowing of food. Patients with neurological disorders have impaired speech and swallowing problem. In this work, a device is envisioned to provide a non-invasive rehabilitation aid for speech and swallowing disorders. The proposed device serves as both diagnostic and therapeutic tool. The parameters of the proposed device are tongue pressure measurement and tongue color detection along with neuromodulation stimulator (tongue stimulator – therapeutic aid). The output, which is a waveform (tongue pressure) and an image (tongue color) are transmitted wirelessly outside the oral cavity to the computer. This device is used to investigate and quantify the degree of tongue disorder. Periodic rehabilitation therapies along with the proposed device, increases the chances of recovery of functional tongue disorders by 50% within a short interval of time.

The main purpose of this paper is to preserve the patient’s medical images and electronic records in the healthcare centre for enabling the distribution of patient data and exchange between networked hospitals andhealthcare centres. The healthcare centre and hospitals have to provide assuranceof security, legitimacy and supervision of medical images and information overstorage and distribution, the watermarking techniques are rising to provide security for medical healthcare information. The medical data’s and electronic patient’s record can be encrypted in secret format then the embedded EPR information and medical images are to be saved in storage space andtransmission overheads and provide assurance security of the shared information. The discrete wavelet packet transform (DWPT) method is novel approach to shielding the patient statistics of themedical image by means of the hospital logo as anallusion image. Several error correction and detection techniques are used to provide greater security to medical information mainly concentrated on forward error correction code (FEC), and BCH code, to improve the robustness of the proposed method.

Published: October 2020

This study offers an inventive way to decrease the stain sound which linked with the ultrasound imaging. This in revolve leads to humanizing the input image and raise the human analytical presentation. It uses an Undecimated Wavelet Transform UWT to decay the image signal to the coefficients, to take the oblique coefficient and applied Independent Directional Mask after replacing the value of each pixel in this coefficient with the comparable pixel in the innovative image, this result yields after applying middle filter in container the value of the pixel is smaller than the entrance value which is pre-specified. We suitable the Directional filter and transmit the design of the new oblique coefficient, and then make the converse wavelet renovate to form the resulting image after dropping the sound of it. The method showed a clear enhancement on numerous ultrasound images via conventional arithmetical measurements and outperformed the other methods which used in common to diminish the noise.

Authors: Litovchenko O , Maximova A
Published: October 2020

Aim. The paper aims to reveal the features of the central nervous system and interhemispheric asymmetry in volleyball players with hearing impairment. Materials and methods. The study involved 14 athletes of various sports experience with varying degrees of hearing impairment aged from 20 to 35 years (average age 29.20 ± 1.3 years). Simple visual reaction was studied in terms of the reaction time, reaction stability, and functional capabilities of the nervous system. To establish the manual asymmetry, the M. Annette questionnaire and motor tests (dynamometry, tests for intertwined fingers, the applause test) were used, the coefficient of the right hand was calculated. When detecting visual asymmetry, the Rosenbach test and the telescope test were used. The coefficient of the right eye was also calculated. Results. It was established that a third of the examined athletes had a symmetric distribution of signs in both the visual and manual spheres. The reliable dependence between symmetric distribution and sports titles was not found. The reaction time in volleyball players with hearing impairment was reduced. The reaction stability and the level of functional capabilities were within the normal range and had a significant dependence on the sports rank and category. Conclusion. It was revealed that volleyball players with hearing impairment formed a special type of interhemispheric interaction characterized by a more uniform distribution between the right and left hemispheres, which resulted in low values of manual and visual asymmetry.
Differential Inhibition of the Brain Acetylcholinesterase Molecular Forms Following Sarin, Soman and VX Intoxication in Laboratory Rats
Authors: Bajgar Jiří
Published: October 2020

The female Wistar rats were intoxicated (i.m.) with sarin, soman and VX in doses equal to 1xLD50 and pontomedullar areas of the brain were prepared, homogenized, centrifuged and in these samples, acetylcholinesterase (AChE, EC 3.1.1.7) activities were determined. In the same samples, AChE was separated using polyacrylamide gel electrophoresis and AChE molecular forms were detected and densitometrically evaluated. In control animals, AChE was separated into four forms differing in their electrophoretic mobility and their quantitative content in the sample. The form with lowest electrophoretic mobility represent the main part of AChE activity constituting the whole enzymatic activity. Following intoxication with the nerve agents mentioned, the whole AChE activity in the pontomedullar area of the brain was decreasing in intervals of ten minutes (soman and sarin) or one hour (VX). The AChE activity at the time of death (or terminal stage) was represented 5-30 % of controls. Molecular forms of AChE were inhibited in different extent: the form with lowest electrophoretic mobility was diminished to zero level while the form with the highest mobility was practically unaffected, independently on the type of nerve agent. From quantitative expression of percentage content of the forms vs their activity we can imply that values of the total AChE activity represent the ãmeanÒ activity of the forms determined.

Authors: Pidrman Vladimír , Tůma Ivan
Published: October 2020

Obsessive-compulsive disorder is a chronic psychiatric illness, affecting up to 3% of the general population, to the midle of 60-th it was supposed to be untreatable. Antidepressant pharmacotherapy is one of the treatment alternatives today. We compared efficacy and safety of citalopram versus clomipramine (serotoninergic antidepressants) in 6 weeks in double blind therapy of obsessive-compulsive disorder. The second objective was to compare prolactin response to a fenfluramine challenge test before the treatment of patients and after 6 weeks of the treatment. In a sample of 14 patients we confirmed significant therapeutic response after 3 weeks of pharmacoterapy, better in obsession than in compulsion. We found low level of adverse effects in the first week of therapy - dry mouth, anxiety, nausea, somnolence, tremor, and sexual adverse events. There were no changes in the laboratory, test EEG, and ECG examinations. Fenfluramine challenge test showed statistically significant decrease of prolactine levels 1 hour after administration of fenfluramine. It was not observed after six weeks of the therapy. Statistically significant negative correlation between prolactine plasma levels at the 6-th hour after administration of fenfluramine and obsession item of YBOC Scale was showed after the 3-rd and 6-th week of the therapy. The correlation was not observed for compulsion item YBOC Scale. Side effects observed during and after the challenge test were anxiety and nervousness and gastrointestinal problems, lasted from l hour to 10 hours. These preliminary result could support the idea, that obsessions and compulsions have not necessary the same biological background. The challenge paradigm appears to be a possible way to clarify the pathogenesis of OCD. Our study will continue.
A Central Amygdala-Globus Pallidus Circuit Conveys Unconditioned Stimulus-Related Information and Controls Fear Learning

Published: October 2020

The central amygdala (CeA) is critically involved in a range of adaptive behaviors, including defensive behaviors. Neurons in the CeA send long-range projections to a number of extra-amygdala targets, but the functions of these projections remain elusive. Here, we report that a previously neglected CeA-to-globus pallidus external segment (GPe) circuit plays an essential role in classical fear conditioning. By anatomic tracing,in situhybridization and channelrhodopsin (ChR2)-assisted circuit mapping in both male and female mice, we found that a subset of CeA neurons send projections to the GPe, and the majority of these GPe-projecting CeA neurons express the neuropeptide somatostatin. Notably, chronic inhibition of GPe-projecting CeA neurons with the tetanus toxin light chain (TeLC) completely blocks auditory fear conditioning.In vivofiber photometry revealed that these neurons are selectively excited by the unconditioned stimulus (US) during fear conditioning. Furthermore, transient optogenetic inactivation or activation of these neurons selectively during US presentation impairs or promotes, respectively, fear learning. Our results suggest that a major function of GPe-projecting CeA neurons is to represent and convey US-related information through the CeA-GPe circuit, thereby regulating learning in fear conditioning.

SIGNIFICANCE STATEMENTThe central amygdala (CeA) has been implicated in the establishment of defensive behaviors toward threats, but the underlying circuit mechanisms remain unclear. Here, we found that a subpopulation of neurons in the CeA, which are mainly those that express the neuropeptide somatostatin, send projections to the globus pallidus external segment (GPe), and this CeA-GPe circuit conveys unconditioned stimulus (US)-related information during classical fear conditioning, thereby having an indispensable role in learning. Our results reveal a previously unknown circuit mechanism for fear learning.

Contribuições da Pedagogia Progressista Libertadora para a Educação Inclusiva Frente ao Contexto Neoliberal
Authors: Machado Fernando Soares , Ribeiro Elisa Antônia , De Lima Geraldo Gonçalves
Published: October 2020

O discurso de inclusão educacional, voltado à igualdade de oportunidades e à educação para todos, camufla-se sob o domínio das teorias educacionais de base econômica instituídas nas políticas públicas brasileiras, com fins produtivistas, que exacerbam o individualismo e as desigualdades. As teorias progressistas confrontam-se a esse sistema propondo uma educação pautada na luta de classes e na transformação social. O presente estudo tem como objetivos compreender a concepção das políticas direcionadas à educação inclusiva no cenário brasileiro, a partir dos anos de 1990, por influência do neotecnicismo pedagógico, e apresentar possíveis contribuições da teoria progressista libertadora para a inclusão educacional. O método utilizado tomou como base uma pesquisa qualitativa, envolvendo a análise da legislação referente ao tema (documental) e bibliográfica, a partir de publicações de autores que discutem a inclusão como apropriação do neoliberalismo e das ideias defendidas por Paulo Freire. Assim, a pedagogia libertadora fundamenta-se como uma alternativa de ruptura da lógica neoliberal ao defender uma educação dialógica por meio de uma práxis que inclua, que se preocupa com a construção coletiva, crítica, política, consciente e reflexiva, pautada em uma educação enquanto ambiente de transformação dos sujeitos.

Autonomia para ensinar e aprender: pela liberdade na prática pedagógica
Authors: Mateus de Sá Geraldo , Duarte Aldimar Jacinto
Published: October 2020

: Este artigo pretende refletir sobre ensinar e aprender a partir do conceito de autonomia, de Paulo Freire (1921-1997), que pressupõe a pedagogia pautada na liberdade, na democracia e no diálogo. Assim, salienta-se a necessidade da livre manifestação da curiosidade, a fim de que a prática pedagógica autoritária não iniba a invenção e, muito menos, negue a dimensão crítica da aprendizagem existencialmente manifestada no mundo. Em vista disso, fez-se uma análise do conceito de autonomia concernente ao pensamento de Freire, especialmente no que tange à sua obra Pedagogia da autonomia (1996). Dentre os possíveis resultados, conclui-se que a autonomia, além de necessária à práxis pedagógica, constitui também uma real alternativa de uma pedagogia inventiva e autêntica dentro da realidade educacional. A análise em questão evidencia, portanto, que a identidade do pensamento de Freire consiste prioritariamente em uma concepção crítica à autonomia para ensinar e aprender.
Квазі-геодезичні відображення спеціальних псевдоріманових просторів
Authors: Kurbatova Irina , Піструіл М. І.
Published: October 2020

Стаття присвячена досліженню спеціального типу дифеоморфізмів псевдоріманових просторів з афінорною структурою. В [4] вивчалися дифеоморфізми  псевдоріманових просторів, які є квазі-геодезичними відображеннями [2] і водночас майже геодезичними другого типу [3]. За означенням при квазі-геодезичному відображенні, що відповідає афінору $F^h_i$, геодезичні лінії простору $(V_n, g_{ij})$ переходять в так звані квазі-геодезичні лінії іншого простору $(\overline{V}_n, \overline{g}_{ij}, F^h_i)$.  В [4], [8] вважалося, що КГВ $V_n$ на $\overline{V}_n$ задовольняє умові взаємності, тобто  зворотне відображення  також є квазі-геодезичним, відповідаючим тому ж афінору $F^h_i$. При цьому умови на афінор носять суто алгебраїчний характер (узгодженість з метричними тензорами $V_n$ і $\overline{V}_n$). При майже геодезичному відображенні другого типу за означенням геодезичні лінії $(V_n, g_{ij}, F^h_i)$ переходять в майже геодезичні лінії  $(\overline{V}_n, \overline{g}_{ij})$, якщо афінор $F^h_i$ в $V_n$ задовольняє певним диференціальним рівнянням. В \cite{Kurbatova1980} доведено, що сукупність вказаних алгебраїчних і диференціальних умов приводить до того, що  афінор $F^h_i,$    необхідно визначає  на $V_n$  $e-$структуру, і розглянуто еліптичний та гіперболічний випадки.  Ми називаємо  афінорну структуру з такими умовами  узагальнено-рекурентною ( а $V_n$ з такою структурою, відповідно, узагальнено-рекурентним простором)  і обираємо для дослідження квазі-геодезичні відображення узагальнено-рекурентних просторів  параболічного типу. В даній статті знайдено зв'язок тензора Рімана узагальнено-рекурентного простору з вектором узагальненої рекурентності. Доведено, що клас псевдо-ріманових просторів з узагальнено-рекурентною структурою параболічного типу замкнутий відносно розглядуваних відображень, але при цьому вектори узагальненої рекурентності просторів $V_n$ і $\overline{V}_n$ можуть не співпадати.  Якщо вектор узагальненої рекурентності градієнтний, в узагальнено-рекурентному просторі існує $K$-структура. Доведено, що якщо $K$-простір допускає квазі-геодезичне відображення зі збереженням інтегровної $K$-структури параболічного типу, то ця $K$-структура - келерова, хоча сама по собі інтегровна $K$-структура параболічного типу може не бути келеровою. Знайдена структура тензора Рімана узагальнено-рекурентного простору параболічного типу, який допускає квазі-геодезичне відображення на плоский простір. Приведено компоненти метричного тензора такого простору в спеціальній системі координат.

Abstract: The Ribeira de Iguape River basin has about 100 fish species. This study aimed to characterize the fish community from “serranias costeiras” of the Ribeira de Iguape River basin. Samplings were conducted with electrofishing during the dry season in the years 2018-2019. The sampling effort consisted of 30 streams stretches. As a result, 50 species were captured, distributed in 37 genera, 11 families, and six orders. The species richness estimate (SChao1) was 57 species, and the coverage estimate for the entire data set was C = 0.998. Harttia kronei and Chasmocranus lopezae are endemic species and can be used as bioindicators of streams in this river basin. We captured approximately nine species by stream stretch. Beta diversity was found to be more critical for gamma diversity than alpha diversity. This finding highlights the streams environmental heterogeneity importance for maintaining regional fish diversity. We captured eight individuals of the threatened species Spintherobolus papilliferus and this indicates an expansion in the geographic distribution of this species.

AUTORIZAR-SE À SEXUALIDADE NA ADOLESCÊNCIA
Authors: Westphal Laure , Hoffmann Christian
Published: October 2020

RESUMO: A inscrição do significante do Nome-do-Pai subordina a sexualidade infantil à função fálica. Ela permite ao sujeito inscrever-se em uma relação gerida pelo gozo e optar por uma identificação sexuada. Ora, a sexualidade genital na adolescência pode, ao contrário, reatualizar a forclusão do nome e do falo, cujo manejo é necessário ao engajamento do corpo na relação com o outro. A clínica nos ensina que o sujeito pode se autorizar alguns artifícios como a religião ou a prostituição, isto é, um saber fazer, que lhe permite prescindir-se do pai à condição de se servir dele. Por vezes, também, a fobia como forma de questionar o nome é capaz de ser superada.

Published: October 2020

RESUMO: A partir de questões suscitadas pela clínica da recepção em um ambulatório público de saúde mental, investigamos o manejo clínico da urgência subjetiva. Tendo em vista a recorrência do sofrimento psíquico relacionado à angústia e a manifestações ligadas ao ato, revisamos o lugar da angústia em psicanálise e sua relação com o acting out e a passagem ao ato. Verificamos como o psicanalista pode acolher a urgência subjetiva, permitindo que este momento de crise dê lugar ao trabalho psíquico e possibilite uma subjetivação do sofrimento.

Considera a obra e, em certo sentido, a vida do escritor Wilson Bueno, extraindo de seu entrelaçamento consequências analíticas que trazem, a um mesmo plano de exame, as noções de sublime-ação e sinthoma, esta última tal como é concebida por Lacan. Serão ainda empregados conceitos deleuzianos, nietzschianos e bergsonianos que devem oferecer perspectivas éticas e clínicas de inesperado alcance ao saber analítico.

Authors: Castro Priscila Rodrigues de
Published: October 2020

Resumo Este artigo é uma reflexão sobre as potencialidades do uso das Tecnologias de Informação e Comunicação (TICs) destacando as mídias digitais como instrumento das lutas feministas. Estas plataformas virtuais ampliam o alcance das discussões das pautas feministas, paradoxalmente permitem ataques de movimentos e manifestações contrárias. O que ressaltamos é a importância fundamental do uso destes instrumentos de comunicação para o processo de mobilização popular, estratégia indispensável para a luta política, em que pesem as diferentes formas de comunicação possibilitadas pela Internet, sua visibilidade e seu alcance. Os desdobramentos podem ser percebidos mediante as frequentes manifestações sociais brasileiras materializando as articulações estabelecidas por essas linguagens digitais.
Entre a vida e a morte: Estado, racismo e a “pandemia do extermínio” no Brasil
Authors: Sampaio Simone Sobral , Meneghetti Gustavo
Published: October 2020

Resumo Escrito em tempos de pandemia sanitária, este artigo aborda uma outra grave “pandemia” em curso no Brasil, que tem provocado o extermínio sistemático, principalmente, dos negros/pobres/jovens, cujas vidas são consideradas descartáveis. Mostra como o Estado se utiliza do racismo estrutural para controlar a vida e a morte dos corpos negros. Enfatiza que a lógica da criminalização e do extermínio é essencialmente política: para manter a ordem social vigente, é preciso controlar a rebeldia popular.

SOL E AR FRESCO NO COMBATE À TUBERCULOSE: EXPERIÊNCIAS DE EDUCAÇÃO AO AR LIVRE NO RIO DE JANEIRO (1910-1920)
Authors: Dalben André , Silva Henrique Mendonça da
Published: October 2020

RESUMO O Rio de Janeiro criou o Serviço de Inspeção Médica Escolar em 1910. Desde então, médicos e educadores promoveram uma série de debates, registrados em relatórios, periódicos, livros e na imprensa, sobre as melhores formas de prevenir o alastramento da tuberculose entre escolares. O artigo apresenta e analisa algumas discussões e medidas postas em prática por médicos e educadores na cidade durante as décadas de 1910 e 1920 para o enfrentamento da tuberculose infantil. Como solução foram propostos e implementados solários, preventórios, colônias de férias infantis e escolas ao ar livre.
A linguagem poética e a criança: ouvir, ler, criar, fruir e brincar

A palavra poética, aqui compreendida como dialógica – numa concepção bakhtiniana de linguagem –, mostra-se com duas faces: procede de alguém e se direciona a alguém. É ela que nos possibilita apresentar neste texto os encontros “poesia e criança” vivenciados e refletir acerca dos aspectos que consideramos mais relevantes das interações estabelecidas entre ambas. O artigo reúne parte de investigação de Doutorado em Educação cuja pesquisa de campo propiciou encontros poéticos com crianças em uma escola da rede pública estadual de Criciúma-SC. Neles, foi possível observar a forma pela qual as crianças acolhem, dispensam atenção e interagem com os poemas a elas apresentados, ou por elas trazidos e compartilhados. A metodologia utilizada é denominada “espaços de narrativa” (LEITE, 2008), caracterizada pela realização de encontros sistematizados entre observador e sujeitos, empregando estratégias de natureza etnográfica e uso de diferentes instrumentos para captura de dados, especialmente gravação em vídeo. As palavras sobre poesia e as palavras poéticas lidas, ouvidas, fruídas e/ou inventadas nos encontros abrem um espaço-tempo reflexivo que ajuda a pensar algumas questões: o que as crianças entendem por poesia? Elas apreciam poesia? As crianças têm um acervo poético? Como lidamos com a poesia que as crianças nos apresentam? Como abordar a linguagem poética com crianças no campo da pesquisa e no espaço da escola? A problematização da temática se faz com interlocutores dos campos da linguagem, da literatura, em especial da poesia, da educação e da infância, como Bakhtin (2011), Benjamin (2002, 2013), Vigotski (2009), Paz (2012) e Kirinus (2008).
Isolation of selected possible aerobic bacterial pathogens from dental environmental surfaces after use of disinfectants - A case study at a public dental clinic, in KwaZulu-Natal

Cross infection in the dental clinical environment remains a low priority in conversations around oral health care despite the high risk of exposure to blood and airborne infections. The aim of this study was to determine the presence of selected pathogens after use of disinfectants on specific dental environmental surfaces at a public oral health facility in KwaZulu-Natal. This was a cross-sectional descriptive case study with a non-experimental design. The dental clinical environment was divided into four zones and 9 dental units were systematically selected. Swabs were collected from the 26 identified areas at specific time intervals (7.00, 9.00, 11.00, and 16.00) after the use of chlorine, ethanol (70% in water) and glutaraldehyde (2%) as surface disinfectants. The collected swab samples were cultured in nutrient agar media for two days at 37°C. The colony forming units were then examined and characterized using the MALDI-TOF spectrometer. Out of the 312 samples taken, 262 (84%) were shown to be bacterial culture positive. The most contaminated areas in the dental environment were around the chair area (86.53%) and the area away from the chair (92%). Glutaraldehyde was found to be more effective than chlorine and ethanol. The study suggests an association between the frequency of cleaning, the type of disinfectant used and the bacterial microbial count on the specified dental environmental surfaces at the identified oral health facility.
Conformity of removable partial denture designs to agreed principles based on materials used - A preliminary study
Authors: Farao Warren , Geerts Greta
Published: October 2020

Removable partial denture (RPD) designs may differ based on types of materials used. The aim of the study was to investigate how a sample of non-metal clasp (NMC), acrylic and metal RPD designs complied with biomechanical design principles. This cross-sectional study examined 60 clinical designs of NMC, acrylic and metal RPDs at 3 commercial dental laboratories in the Cape Town Metropole, at the stage when the dentures were ready for transport to dentists. Retention, indirect retention, support, soft tissue cover, and cross-arch design features were recorded and compared with “ideal” control designs developed by 2 experts in the specialty of prosthodontics. Fifty five % of the clinical designs had no rests, hence were mucosa supported. None of the NMC and only 35% of acrylic RPDs had some rests. A total of 35 clinical designs required indirect retention, but it was only provided in 14 (40%) of them. Eighty five % of acrylic RPDs had no clasps; metal RPDs had more clasps than required while NMC RPDs had slightly less clasps than required. Ratio teeth covered/replaced was most favourable for metal (0.91), followed by acrylic (1.83) and NMC (1.80) RPDs. Cross – arch stabilization was absent in 22% of clinical designs, all of them from the NMC group. Of the 3 types of RPDs, metal RPDs complied best with requirements in terms of tissue support (mostly tooth and mixed tooth/mucosa), retention, cross-arch stabilization and “open” design. Acrylic RPDs provided crossarch stabilization but were lacking in all other aspects. Except for direct retention, NMC RPDs did not conform to any of the agreed biomechanical requirements for RPDs assessed in this study.

Published: October 2020

Introduction. Rural Americans (RA) have poorer vascular health and physical activity levels than their urban counterparts; all are dementia risk factors. Dementia risk reduction among rural individuals requires a tailored approach. The purpose of this project was to examine preliminary efficacy of a community-based physical exercise and/or dementia risk factor-reduction curriculum among rural adults 50 and older.

Methods. Seventy-five rural dwelling adults 50 and older were randomized to one of three groups: 1) 10 weeks of Alzheimer’s disease risk-reduction education (ED), 2) risk-reduction education and supervised exercise (EDEX) or 3) control group (CON). Outcomes included baseline to 10-week follow-up difference in dementia knowledge (primary outcome) and physical activity, muscular endurance, healthy lifestyle engagement, and anthropometrics (secondary outcomes).

Results. Sixty-nine adults successfully completed the 10-week study. Dementia knowledge increased in a Treatment Arm-dependent manner (χ2 = 6.95 (2), p = 0.03), being ED and EDEX superior to CON. Engagement in healthy lifestyle behaviors did not change statistically. However, participation specifically in physical activity increased over time (χ2 = 11.47 (2), p = 0.003) with EDEX reporting the greatest increases. No significant change in average daily steps was observed for any group.

Conclusion. The results suggested dementia risk-reduction education, both with and without structured exercise, leads to improvements in dementia knowledge. When coupled with regular, supervised exercise, this education intervention also helped participants increase engagement in physical activity over 10 weeks. Tailored interventions that combine Alzheimer’s disease education and regular, supervised exercise may help reduce dementia risk in rural communities.

Published: October 2020

Introduction. Methotrexate (MTX) is an immunosuppressive and anti-inflammatory drug used to treat rheumatoid arthritis (RA) and other autoimmune conditions. MTX is transported into cells, where glutamate moieties are added and is retained as methotrexate polyglutamates (MTXPGs). In the RA literature, it has been reported that the degree of polyglutamation correlates with the anti-inflammatory effect of MTX in RA. There are no prior studies evaluating the relationship between MTXPGs and myasthenia gravis (MG) outcome measures. The objective of this study was to assess the correlation between methotrexate (MTX) polyglutamates (MTXPGs) with Myasthenia Gravis (MG) outcome measures.

Methods.xAn analysis was done of blood drawn from patients enrolled in the 12-month randomized, placebo-controlled study of MTX in MG study. Red blood cell MTXPGs were measured via ultraperformance liquid chromatography and tandem mass spectrometry. MTXPG was correlated to MG outcome measures using Spearman Correlation Coefficient. A two-group t-test was used to determine the difference in MTXPG based on clinical outcome responder definitions.

Results. Twenty-one polyglutamate samples were analyzed of subjects on MTX while eight samples were analyzed from subjects on placebo. Pentaglutamate had the strongest correlation with the MG-ADL (0.99), while tetraglutamate had the strongest correlation with the QMG (0.54). Triglutamate had the strongest correlation with MGC (0.76).

Conclusion. There were variable correlations between MTXPG1-5 and MG outcomes (rho range: 0.08 to 0.99). There are strong correlations between MTXPG and the MG-ADL, QMG, and MGC. Long chain methotrexate polyglutamates correlate better with MG outcomes.
Impact of Cigarette Smoking on Re-operation and Revision Surgery after Femoral Neck Fracture Treatment
Authors: Messner Mitchell , Chong Alexander , Piatt Bruce
Published: October 2020

Introduction. Smokers and nicotine users have a higher risk of femoral neck fracture non-union and prolonged time to fracture union. The impact of smoking resulting in revision surgery after fixation of femoral neck fractures, however, rarely has been studied. The aim of this retrospective study was to review if cigarette smoking had an influence on re-operation and revision after femoral neck fracture treatment.

Methods. Three groups of patients (Group 1: active smokers; Group 2: former smokers; and Group 3: non-smokers) who sustained a femoral neck fracture from January 2012 through August 2018 were included. Outcomes investigated included femoral neck fracture type, operative fixation type, fixation failure, and time interval between initial fixation and revision.

Results. A total of 1,452 subjects were identified (Group 1: 165 subjects; Group 2: 507 subjects; and Group 3: 780 subjects). In the male population, Groups 1 and 2 had higher rates of femoral neck fracture than Group 3. Twelve cases required revisions (Group 1: three cases (6%); Group 2: two cases (2%); Group 3: seven cases (4%)), with all but one revision within the first year following initial fixation. Group 1 patients tended to be younger than the other two groups.

Conclusion. Smoking has a positive association with the risk of femoral neck fracture amongst active and former male smokers. This study concluded that active smokers have a higher risk of non-union compared with non-smokers or former smokers. Smoking history, especially heavy or long-term, should play a role in deciding which fixation construct type to use for femoral neck fractures.
