Published: August 2021

ABSTRACT Objectives: to establish the prevalence of salvage of central venous catheters in newborns with bloodstream infection caused by coagulase-negative staphylococci. Methods: retrospective cross-sectional study with 136 newborns admitted to the Neonatal Intensive Care Unit between 2011 and 2017. The total of 143 infection events undergoing antibiotic therapy were evaluated. Results: among the 143 infection events, 39 catheters in which antibiotic therapy was used were saved and in 69 cases, the device was removed. Positive central blood culture and single lumen catheter were factors associated with salvage failure. The probability of salvage decreased with infections diagnosed from 15 days of using the catheter. Negative blood culture raised the chance of salvage by fourfold. Conclusions: the use of antibiotic therapy in the treatment of infections resulted in a low prevalence of salvage of the central venous catheter. The probability of salvage was associated with variables of the device.

ABSTRACT Objectives: to compare adverse events after administrating hepatitis A vaccine intramuscularly in the ventro-gluteal region between techniques with and without aspiration. Methods: randomized double-blind clinical trial, using hepatitis A vaccine (inactivated) in the ventro-gluteal region, with a sample of 74 participants in the intervention group, vaccinated with the slow injection technique without aspiration, and 74 participants in the control group undergoing slow injection with aspiration. Daily assessment of participants was carried out in the 72 hours after vaccination, in order to ascertain local, systemic adverse events, local and contralateral temperatures. Results: the occurrence of local and systemic adverse events was homogeneous between the groups in the three days after vaccination (p>0.05). There was no influence of sex, race, pre-existing disease and use of medication. Conclusions: the intramuscular vaccination technique without aspiration in the ventro-gluteal region is safe for adverse events following immunization compared to the conventional technique with aspiration.

Resumo O presente trabalho aborda a quantificação e a dispersão de poluentes atmosféricos no entorno de uma indústria siderúrgica em uma zona portuária do litoral do Nordeste Brasileiro (a Companhia Siderúrgica do Pecém, CSP), investigando alguns impactos sobre comunidades e ecossistemas locais. Para esta finalidade, foram analisados os parâmetros medidos pelas estações de monitoramento do órgão ambiental do estado do Ceará sobre os níveis da qualidade do ar no entorno da região onde se encontra instalada a indústria siderúrgica em questão e realizadas simulações matemáticas de dispersão de poluentes. As medidas foram feitas em duas posições: uma, onde se localiza a estação fixa de monitoramento; a outra, onde foi posicionada uma estação móvel por um período limitado. Dada a direção predominante dos ventos atuantes na região, verificou-se que a estação fixa não se mostra capaz de identificar a poluição produzida a partir da indústria siderúrgica, pois a mesma se encontra a barlavento das fontes poluentes. Observou-se em particular que as concentrações de material particulado e gás metano (CH4) apresentaram elevação entre as medidas das duas estações de monitoramento, a leste e a oeste da siderúrgica, indicando uma influência direta da instalação industrial na qualidade do ar na região.

Published: August 2021

Resumo O objetivo geral da pesquisa foi discutir como os desastres naturais identificados no Estado do Ceará se relacionam com a variabilidade climática, destacando-se aqueles associados à precipitação, no período de 1991 a 2019. No que alude à metodologia, adotou-se pesquisa descritiva, explicativa e de natureza qualitativa-quantitativa. Tratou-se de um estudo de caso, cuja técnica de coletas de dados partiu de pesquisa documental e bibliográfica. A análise de dados foi feita a partir da estatística multivariada, por meio de regressão não-linear e coeficiente de correlação de Pearson. Os dados climáticos foram obtidos, principalmente, a partir da Fundação Cearense de Meteorologia e Recursos Hídricos (FUNCEME), já os registros de desastres, através da Coordenadoria Estadual de Defesa Civil do Ceará (CEDEC-CE) e Universidade Federal de Santa Catarina (UFSC). Os resultados obtidos mostraram que os desastres naturais com maior número de registros foram as estiagens e secas, correlacionando-se de forma alta e negativa com as chuvas, associando-se ao fenômeno El Niño e/ou às condições oceano-atmosféricas desfavoráveis às chuvas do Atlântico tropical. Já as inundações, as enxurradas, os alagamentos e as chuvas intensas constituíram o segundo grupo de tipificações de desastres examinados, correlacionando-se de forma moderada e positiva com as chuvas, associando-se ao fenômeno La Niña e/ou às condições oceano-atmosféricas favoráveis às chuvas do Atlântico tropical. Logo, concluiu-se que há uma tendência de aumento do número de desastres naturais no Ceará, os quais estão relacionados com a variabilidade climática.

Published: August 2021

ABSTRACT: Continued unsustainable exploitation of natural resources promotes environmental degradation and threatens the preservation of dry forests around the world. This situation exposes the fragility and the necessity to study landscape transformations. In addition, it is necessary to consider the biomass quantity and to establish strategies to monitor natural and anthropic disturbances. Thus, this research analyzed the relationship between vegetation index and the estimated biomass using allometric equations in different Brazilian caatinga forest areas from satellite images. This procedure is performed by estimating the biomass from 9 dry tropical forest fragments using allometric equations. Area delimitations were obtained from the Embrapa collection of dendrometric data collected in the period between 2011 and 2012. Spectral variables were obtained from the orthorectified images of the RapidEye satellite. The aboveground biomass ranged from 6.88 to 123.82 Mg.ha-1. SAVI values were L = 1 and L = 0.5, while NDVI and EVI ranged from 0.1835 to 0.4294, 0.2197 to 0.5019, 0.3622 to 0.7584, and 0.0987 to 0.3169, respectively. Relationships among the estimated biomass and the vegetation indexes were moderate, with correlation coefficients (Rs) varying between 0.64 and 0.58. The best adjusted equation was the SAVI equation, for which the coefficient of determination was R² = 0.50, R2aj = 0.49, RMSE = 17.18 Mg.ha-1 and mean absolute error of prediction (MAE) = 14.07 Mg.ha-1, confirming the importance of the Savi index in estimating the caatinga aboveground biomass.

ABSTRACT: Eurytrema coelomaticum is a trematode reported in the pancreatic ducts of ruminants. It is conjectured that may cause disorders in the pancreas, as well as digestive and metabolic processes dependent on them. This study, determined if there is an impairment of exocrine pancreatic function, and correlated it with parasite burden. Pancreas, blood, and fecal samples were collected from 119 bovines at a abattoir. Stool samples were subjected to the gelatin and x-ray film digestion tests (to detect the presence of trypsin in feces). Using blood samples, the following biochemical tests were performed: amylase, lipase, glucose, fructosamine, cholesterol, triglycerides, total protein, albumin, and globulins. Analyses were correlated with pancreatic parasite burden. Cattle with a high parasitic load presented higher incidence of negative tests in both gelatin digestion and x-ray film digestion tests (P < 0.001) when compared to non-parasitized animals and those with a low parasitic load. Changes in those tests only occurred if the parasitemia was moderate or severe. The activity of the amylase and lipase enzymes was significantly higher in animals with low parasitemia (P < 0.05), compared to non-parasitized animals and with a high parasitic burden. In this study, in cases of high parasitemia, negative results were observed in both gelatin and x-ray film in the feces digestion tests. However, the low infection of E. coelomaticum, higher levels of serum amylase and lipase that also indicated loss of pancreatic exocrine functions were reported.

Published: August 2021

ABSTRACT Introduction: A new exercise electrocardiogram (ECG) detection system was investigated in this study to diagnose and analyze cardiopulmonary function and related diseases in a comprehensive and timely manner and improve the accuracy of diagnosis. Besides, its reliability and clinical applicability were judged. Objective: A new type of exercise ECG detection system was constructed by adding parameters such as respiratory mechanics, carbon dioxide, and oxygen concentration monitoring based on the traditional ECG detection system. Methods: The new system constructed in this study carried out the ECG signal detection, ECG acquisition module, blood pressure and respiratory mechanics detection and conducted a standard conformance test. Results: The heart rate accuracy detected by the exercise ECG system was greatly higher than that of the doctor's manual detection (P < 0.05). The accuracy of the new exercise ECG detection system increased obviously in contrast to that of the manual detection result (P < 0.05). The key technical index input noise and input impedance test results (24.5 μV and 12.4 MΩ) of the exercise ECG detection system conformed to the standard (< 30 μV and > 2.5 MΩ). The common-mode rejection and sampling rate test results (103.5 dB and 515 Hz) of key technical indicators in the exercise ECG detection system were all in line with the standards (≥89 dB and ≥500 Hz). Conclusion: The complete exercise ECG detection system was constructed through the ECG acquisition module, blood pressure detection, and respiratory mechanics detection module. In addition, this system could be applied to detect ECG monitoring indicators with high accuracy and reliability, which could also be extensively adopted in clinical diagnosis.

Abstract Acacia auriculiformis A. Cunn. Ex Benth. (Fabaceae), a non-native pioneer species in Brazil with fast growth and rusticity, is used in restoration programs. Our goal was to assess during a 24-month survey the pattern of arthropods (phytophagous insects, bees, spiders, and predator insects) on the leaf surfaces of A. auriculiformis saplings. Fourteen species of phytophagous, two of bees and eleven of predators were most abundant on the adaxial surface. The values of the ecological indexes (abundance, diversity, and species richness) and the rarefaction, and k-dominance curves of phytophagous, bees and arthropod predators were highest on the adaxial leaf surface of A. auriculiformis. The k-dominance and abundance of Aleyrodidae (Hemiptera) (both leaf surfaces), the native stingless bee Tetragonisca angustula Latreille (Hymenoptera: Apidae) (both leaf surfaces) and the ant Brachymyrmex sp. (adaxial surface) and Pheidole sp. (Hymenoptera: Formicidae) (abaxial surface) were the highest between the taxonomic groups of phytophagous, bees, and predators, respectively on A. auriculiformis saplings. The ecological indexes and rarefaction, abundance, and k-dominance curves of phytophagous insects, bees, and predators were highest on the adaxial leaf surface. The preference of phytophagous insects for the adaxial leaf surface is probably due to the lower effort required to move on this surface. Understanding the arthropod preferences between leaf surfaces may help to develop sampling and pest management plans for the most abundant phytophagous insects on A. auriculiformis saplings. Also, knowledge on the preference pattern of bees and predators may be used to favour their conservation.

Abstract A total of 10 specimens were captured from selected sites of Bajaur Agency FATA, Pakistan using mist nets. The captured specimens were morphologically identified and various morphometric measurements were taken. The head and Body length (HB) of Pipistrellus coromondra and Pipistrellus kuhlii lepidus (n=10) was 43±0.11 mm and 45±1.1 respectively. Morphologically identified Pipistrellus kuhlii confirmed as Pipistrellus kuhlii lepidus based on 16S rRNA sequences. The DNA sequences were submitted to GenBank and accession numbers were obtained (MN 719478 and MT430902). The available 16S rRNA gene sequences of Pipistrellus coromondra and Pipistrellus kuhlii lepidus were retrieved from NCBI and incorporated in N-J tree analysis. Overall, the interspecific genetic variations among Pipistrellus coromondra and Pipistrellus kuhlii lepidus were 8% and 1% respectively. In our recommendation, a comprehensive molecular identification of bats is need of hour to report more cryptic and new species from Pakistan.

Abstract Physids belong to Class Gastropoda; belong to Phylum Mollusca and being bioindicators, intermediate hosts of parasites and pests hold a key position in the ecosystem. There are three species of Genus Physa i.e. P. fontinalis, Physa acuta and P. gyrina water bodies of Central Punjab and were characterized on the basis of molecular markers High level of genetic diversity was revealed by polymorphic RAPD, however SSR markers were not amplified. The multivariate analysis revealed polymorphism ranging from 9.09 percent to 50 percent among the three Physid species. Total number of 79 loci were observed for the three species under study and 24 loci were observed to be polymorphic. These RAPD fragment(s) can be developed into co dominant markers (SCAR) by cloning and can be further sequenced for the development of the Physa species specific markers to identify the introduced and native species in Pakistan.

Abstract Plasmodium falciparum resistance to Chloroquine (CQ) is a significant cause of mortality and morbidity worldwide. There is a paucity of documented data on the prevalence of CQ-resistant mutant haplotypes of Pfcrt and Pfmdr1 genes from malaria-endemic war effected Federally Administered Tribal Areas of Pakistan. The objective of this study was to investigate the prevalence of P. falciparum CQ-resistance in this area. Clinical isolates were collected between May 2017 and May 2018 from North Waziristan and South Waziristan agencies of Federally Administrated Trial Area. Subsequently, Giemsa-stained blood smears were examined to detect Plasmodium falciparum. Extraction of malarial DNA was done from microscopy positive P. falciparum samples, and P. falciparum infections were confirmed by nested PCR (targeting Plasmodium small subunit ribosomal ribonucleic acid (ssrRNA) genes). All PCR confirmed P. falciparum samples were sequenced by pyrosequencing to find out mutation in Pfcrt gene at codon K76T and in pfmdr1 at codons N86Y, Y184F, N1042D, and D1246Y. Out of 121 microscopies positive P. falciparum cases, 109 samples were positive for P. falciparum by nested PCR. Pfcrt K76T mutation was found in 96% of isolates, Pfmdr1 N86Y mutation was observed in 20%, and 11% harboured Y184F mutation. All samples were wild type for Pfmdr1 codon N1042D and D1246Y. In the FATA, Pakistan, the frequency of resistant allele 76T remained high despite the removal of CQ. However, current findings of the study suggest complete fixation of P. falciparum CQ-resistant genotype in the study area.

Abstract The growth of aquaculture sector is strongly dependent upon the continuous supply of inexpensive fish feed with balanced nutritional profile. However, fish meal (FM) is unable to satisfy this demand due to its scarce supply and high cost. In order to test the potential of cottonseed meal (CSM) as a fish meal replacer, a feeding trial of 12 weeks was conducted to check growth performance and proximate composition of Labeo rohita fingerlings. The protein ration of the test feed was satisfied by replacing FM with CSM at 0, 25, 50 and 75%. Sixteen test diets viz., TD1 (control), TD2, TD3, TD4, TD5, TD6, TD7, TD8, TD9, TD10, TD11, TD12, TD13, TD14, TD15 and TD16 were supplemented with citric acid (CA; 0 and 2.5%) and phytase (PHY; 0 and 750 FTU/kg) in a completely randomized design with 3×3 factorial arrangement. The highest weight gain (11.03g), weight gain% (249.21%), specific growth rate (1.39) and best feed conversion ratio (1.20) were recorded by fish fed with TD12. Furthermore, the same level increased the crude protein (59.26%) and fat (16.04%) being significantly different (p<0.05) than that of control. Conclusively, the addition of acidified phytase (CA; 2.5%, PHY; 750 FTU/kg) in TD12 (CSM=50%) led to the improved growth and proximate composition of L. rohita fingerlings.

Published: August 2021

Resumo O artigo propõe uma discussão sobre as imbricações entre gênero e nação na Turquia, analisando como diferentes projetos de nação mobilizam questões de gênero e produzem discursos acerca de feminilidades e masculinidades que influenciam políticas de gênero no país. Argumentamos que dicotomias rígidas entre projetos ditos ‘progressistas’ ou ‘atrasados’ não se sustentam, dado que as premissas de que corpos e comportamentos de mulheres devem ser regulados e que a restrição de liberdades e direitos pode ser justificada em nome da (des)igualdade de gênero e da (ausência ou excesso de) liberdade sexual são amplamente compartilhadas no país.

Num segundo momento, explorando as vicissitudes e o sofrimento do protagonista do texto, lanço mão das noções de interseccionalidade e diferença no intuito de problematizar não apenas a história e a trajetória de um sujeito específico, mas o cenário da geografia político-moral que caracteriza o atual momento da vida brasileira.
Sexualidade e feminilidade: o paradoxo do movimento estético-cultural Kawaii
Authors: Ribeiro Dilton
Published: August 2021

Resumo O kawaii, um adjetivo japonês que significa “fofo”, é também um movimento estético japonês que existe desde a Era Meiji. Nas décadas de 1970 e 1980, contudo, o kawaii surge com um direcionamento mais plural, quebrando barreiras de gênero, dentro de uma estrutura capitalista focado no consumismo e no incentivo a uma democratização de criações e mídias. Esse ambiente é preponderantemente feminino, já que mulheres são criadoras e consumidoras. Ademais, desse espaço advém um certo preconceito aos homens que aderem à cultura kawaii, denominados de otaku, que podem ser vistos como sem masculinidade. Daí decorre, ainda, visões diversas e controversas sobre sexualidade, relacionamentos e estética. Assim, o kawaii é incoerente. Apesar de incorporar elementos que podem ser interpretados como ofensivos às mulheres e até mesmo ilegais, ele possibilita uma expressão do comportamento e estilos mais femininos, lúdicos, individuais e infantis como um movimento oposto ao que preza por uma masculinidade, seriedade e comprometimento com regras e expectativas sociais.

ABSTRACT Objective: To assess the quality of life of people with intestinal stoma and its association with sociodemographic and clinical characteristics. Method: Cross-sectional and analytical study conducted with people with intestinal stoma. An instrument was used for sociodemographic and clinical characterization: COH-QOL-OQ, validated in Brazil. Results: The sample included 152 people with stomas. There were significant differences among all dimensions (p-value < 0.01) of quality of life. The dimension spiritual well-being had the highest mean, with 6.69 (±1.56), followed by the psychological well-being dimension, 5.00 (±1.94), social well-being, 4.63 (±1.83), and physical well-being, 4.54 (±1.77). Marital status, religion, type of stoma, and permanence had statistically significant associations with dimensions of quality of life (p-value < 0.05). Conclusion: The assessment of quality of life in people with intestinal stoma presented lower scores in the physical, social, and psychological dimensions. There was an association between better quality of life scores and people with definitive ileostomy, in a domestic partnership and practicing other religions.

ABSTRACT Objective: To analyze the association between self-reported fragility and quality of life in older adults. Method: Cross-sectional study carried out with Brazilian older adults between July and October 2020. Three instruments were applied to obtain bio sociodemographic, frailty data and quality of life. Data were analyzed using the Kruskal-Wallis test, Pearson correlation and multivariate linear regression, adopting a 95% confidence interval (p < 0.05). Results: A total of 662 older adults participated. All facets of quality of life were significantly and negatively correlated with reduced strength, reduced walking speed, low physical activity, and reported fatigue, with the exception of weight loss. In the regression analysis, different frailty components were associated with quality of life, but all had a negative relationship. Conclusion: Self-reported frailty has a negative relationship with quality of life, that is, the increase in the frailty scale implies a reduction of different magnitudes in the quality of life of older adults.

Published: August 2021

O presente trabalho tem como objetivo apresentar um recorte de pesquisa sobre oferta de formação inicial e continuada para educadores infantis no Sul de Minas Gerais, destacando resultados referentes à percepção de educadores em atuação com relação às suas necessidades formativas. Considerando que a Educação Infantil carrega resquícios de um contexto histórico marcado pelo assistencialismo, em que educadores eram vistos apenas como aqueles que cuidam e interagem e, uma vez que, frente às prerrogativas legais e curriculares é necessário pensarmos a indissociabilidade do cuidar e educar para efetivação do desenvolvimento e da aprendizagem.

The year 2020 saw the covid-19 virus lead to one of the worst global pandemics in history. As a result, governments around the world have been faced with the challenge of protecting public health while keeping the economy running to the greatest extent possible. Epidemiological models provide insight into the spread of these types of diseases and predict the effects of possible intervention policies. However, to date, even the most data-driven intervention policies rely on heuristics. In this paper, we study how reinforcement learning (RL) and Bayesian inference can be used to optimize mitigation policies that minimize economic impact without overwhelming hospital capacity. Our main contributions are (1) a novel agent-based pandemic simulator which, unlike traditional models, is able to model fine-grained interactions among people at specific locations in a community; (2) an RLbased methodology for optimizing fine-grained mitigation policies within this simulator; and (3) a Hidden Markov Model for predicting infected individuals based on partial observations regarding test results, presence of symptoms, and past physical contacts.

Authors: Shave Jon , Jackson Paul , Glendinning Mark , Sadka Ben
Published: August 2021

The documents for structural assessment of highway bridges, bridge substructures, retaining structures and buried structures in the UK's Design Manual for Roads and Bridges have been rewritten and updated. In bringing the documents up to date, there have been several technical changes introduced. These include efficiencies in the traffic loading model for bridges, new content on masonry arch assessment and new approaches to the assessment of substructures, retaining structures and buried structures using a Eurocode-aligned basis of assessment. This paper outlines the technical background to the key changes and highlights some of the efficiencies that can be delivered using the new documents. In addition, the paper outlines how the documents connect with related documents, including those on structural review, assessment of abnormal traffic loads, assessment of impact on bridge piers and the management of substandard structures.
Assessing steel and composite highway structures: background to new UK design standards
Authors: Robinson Peter , Sandberg Jessica , Hendy Chris , Gallagher Jim
Published: August 2021

The UK's design documents for assessment of steel and composite highway bridges and structures have been updated in line with Highways England's overall plan for modernising the Design Manual for Roads and Bridges. This paper describes the key changes that have been made to the document and their impact on users, providing reassurance that, despite the new format, the methods and requirements are largely unchanged, or changed to facilitate future assessments by allowing more general approaches to be adopted. For steel bridges the key changes are described that affect robustness assessment, notch toughness, bearing stiffeners, cross-girders, stiffened panel buckling and inspection criteria for existing welds. For composite bridges, the changes relate mainly to the serviceability limit state verifications, to fatigue and to the shear connection, as well as the general improvements to remove outdated content and simplify the document. The changes for both documents include greater references to the Eurocodes in general, which will facilitate an easier transition to Eurocode assessment standards when these are published in the future.

The documents for risk management and assessment of concrete bridges with half-joints, concrete bridges with deck hinges and post-tensioned concrete bridges in the Design Manual for Roads and Bridges (DMRB) have been rewritten and updated as part of a project to update the entire DMRB suite of documents; they have also been given the new document codes CS 465, CS 466 and CS 467. In bringing these documents up to date there have been significant technical changes introduced, including: a change to the risk management process for half-joints and deck hinges; an update of assessment methods for evaluating half-joints and deck hinges; and improvements to the risk management of post-tensioned bridges. This technical paper outlines the technical background to the key changes and highlights some of the improvements and efficiencies that can be delivered using the new documents.
Development of strategic water resources in England
Authors: Welbank Julian
Published: August 2021

Prompted by policy announcements from government and regulators, a major programme of strategic water resource development in England has commenced, with the aim of addressing the long-term challenges of climate change, population growth and protecting the environment. Among other types of solutions, reservoirs feature heavily as a potential solution, either new reservoirs or enhancements to existing reservoirs. A high-level generic comparison of the solution types indicates that reservoirs have numerous advantages, with their biggest disadvantages being the timescale involved in getting permission to construct the reservoir. The community of reservoir engineers have the opportunity to get involved in articulating the benefits of reservoirs and in formulating the plans for water resources for next 50 years.
Macroeconomic and Financial Risks: A Tale of Mean and Volatility
Authors: Caldara Dario , Scotti Chiara , Zhong Molin
Published: August 2021

We study the joint conditional distribution of GDP growth and corporate credit spreads using a stochastic volatility VAR. Our estimates display significant cyclical co-movement in uncertainty (the volatility implied by the conditional distributions), and risk (the probability of tail events) between the two variables. We also find that the interaction between two shocks--a main business cycle shock as in Angeletos et al. (2020) and a main financial shock--is crucial to account for the variation in uncertainty and risk, especially around crises. Our results highlight the importance of using multivariate nonlinear models to understand the determinants of uncertainty and risk.

Antecedentes: Con base en caracteres morfológicos de hojas, flores y frutos se han segregado nuevas especies del complejo Magnolia mexicana en México. Por su importancia evolutiva, ecológica y de uso medicinal es relevante analizar la variación morfológica y conocer el estado actual de sus poblaciones en su área de distribución.
Preguntas: ¿Existe diferenciación en la morfología de hojas, flores y frutos en las poblaciones de M . mexicana ? ¿Cuál es el estado actual de las poblaciones de M . mexicana ?
Especie de estudio: Magnolia mexicana (DC.) G. Don (Magnoliaceae).
Sitios y años de estudio: El estudio se realizó en seis poblaciones de M. mexicana en la Sierra Madre Oriental, entre mayo y octubre de 2019 y 2020.
Métodos: Se analizaron 480 hojas, 240 flores y 84 frutos mediante análisis univariados y multivariados.
Resultados: Los primeros componentes principales explicaron 85, 69 y 68 % de la variación foliar, floral y frutal, respectivamente; y las primeras 2 funciones discriminantes 82, 66 y 94 % de dicha variación. Los caracteres morfológicos con mayor variación fueron: diámetro del peciolo y  vena media, número de estambres, ancho de carpelos, y largo y ancho de semillas.
Conclusiones: El rango de variación en las características morfológicas de M . mexicana fue más amplio que el documentado en la descripción original de la especie. Las poblaciones están aisladas y presentan baja densidad y alta diferenciación morfológica entre sí, en particular en flores y frutos, por lo que su identidad taxonómica requiere ser corroborada a nivel genético.

Authors: Gaur Priya , Goyal Manu , Singh Gurjant
Published: August 2021

INTRODUCTION: Lumbar Canal Stenosis (LCS) is known as the well-established reason for pain and depleted walking capacity in patients with manifestations of paresthesia and pain in the lower back, gluteal region, posterior thigh, and legs which are termed as ‘Neurogenic Claudication’ (NC). Manual therapy combined with canal enlargement exercises and conventional physiotherapy may be considered in eradicating pain and NC symptoms, hence improving the quality of life. METHODS AND MATERIALS: Patients with LCS with canal diameter 8-12 mm at the level of L4 and below will be recruited for this study. Through the Block randomization method, they will be randomized into two interventional groups: Manual Therapy & Canal Enlargement (MTCE) (n=16) and Conventional Physiotherapy (Cp) (n=16) groups. MTCE group will receive manual therapy and canal enlargement exercises, while the Cp group will receive only conventional physiotherapy. Both interventional groups will receive 3 days of treatment per week for 4 weeks. Modified Oswestry Disability questionnaire (MODI), Antero-Posterior (AP) canal diameter, Numeric Pain Rating Scale (NPRS), and Claudication Distance (CD) will be used for the evaluation. In addition, modified Oswestry Disability Index, AP canal Diameter, NPRS, Claudication distance, an SLR will be measured at baseline and post-intervention. DISCUSSION: The results of this research will dictate the applicability of manual therapy with an exercise protocol of canal enlargement exercises on pain and functional disability in patients with LCS.

Published: August 2021

INTRODUCTION: Craniotomy makes insight and approach towards the brain easier but accompanies ailments. Intensive care units are equipped with trained professional physical therapists working over these deleterious after-effects of this surgical program, but a progressive, defined, and evidence-supported protocol for such patients is lacking. OBJECTIVE: To assess the feasibility of a Neuro-rehabilitation protocol devised for post-craniotomy patients within their stay in the Intensive Care Unit (ICU) to improve their functional outcomes and reduce their length of stay (LOS). MATERIALS AND METHODS: It will be a single group pre-test post-test quasi feasibility trial. Fifteen patients undergoing craniotomy will be recruited for the trial and will be rendered with Neuro-rehabilitation protocol for 60 minutes from the first day of surgery up to 15 days of surgery. The primary outcome will be the Early Functional Abilities (EFA) Scale to measure functional outcomes like conscious level, sensorimotor abilities, cognitive-perceptual abilities, and oro-motor abilities of patients, which will be assessed first-day post craniotomy. Secondary outcomes will include Glasgow Coma Scale (GCS), Coma Recovery Scale-Revised (CRS-R), Sensory Modality Assessment Rehabilitation Technique (SMART), Modified Ashworth Scale (mMAS), Montreal Cognitive Assessment Score (MoCA), and Medical Research Council Scale (MRC). Assessments will be taken on the first and fifteenth days post-surgery. PERSPECTIVES: It is expected that this protocol might improve functional outcomes and may reduce the occurrence of comorbidities in patients after Craniotomy in ICUs.

Published: August 2021

INTRODUÇÃO: As restaurações endocrown têm sido uma técnica de restauração alternativa para dentes tratados endodonticamente destruídos extensivamente. São restaurações protéticas que possuem retenção macromecânica dentro da câmara pulpar de um dente despolpado e microrretenção com técnicas de cimentação adesiva na câmara e nas bordas da cavidade. É um procedimento restaurador menos traumático e proporciona melhor manutenção do remanescente dentário quando comparado à técnica com retentores intrarradiculares, pois não requerem desobstrução do conduto, com resultados estéticos e funcionais satisfatórios em estudos de longo prazo. OBJETIVO: O objetivo deste trabalho é revisar a literatura sobre as restaurações endocrown, bem como seu funcionamento clínico. METODOLOGIA: A revisão foi realizada por meio de levantamento bibliográfico online de artigos científicos nas plataformas Pubmed, Scielo e Google Scholar por meio dos descritores: dente não vital, prótese dentária, reabilitação oral e cerâmica, respeitando o prazo de 1999 a 2020, além de capítulos de livros de referência na prática odontológica. CONSIDERAÇÕES FINAIS: Concluiu-se que o uso da restauração endocrown é uma alternativa confiável para restaurar molares extensamente destruídos endodonticamente tratados, agregando diversas vantagens do ponto de vista funcional e estético. Porém, mais estudos clínicos ainda são necessários para que o uso em pré-molares e dentes anteriores possa ser realizado, com segurança e sucesso, em longo prazo.
