Correlation between balance performance and perception about the knee in patients with osteoarthritis knee
Authors: Bhole Harshita , Ray Manish , Shyam Ashok , Sancheti Parag 
Published: February 2022

BACKGROUND:
Static and dynamic balance impairment is seen in multiple cases of knee osteoarthritis (OA). The affection of body perception has also been observed. Balance and body perception are an integral part while performing daily activities. The affection of these further leads to fear of fall. The aim of this study was to find the relation between balance and knee body perception in primary OA knee patients.

METHODS:
This was a correlational study. Seventy-three patients with primary knee OA were recruited from tertiary care hospitals. Kellgren–Lawrence Grading system (I-IV) was used to assess the severity of knee OA. Patients having pain on the Visual Analog Scale 6/10 or below were included. The Fremantle Knee Awareness Questionnaire was used to assess a patient's body perception about the osteoarthritic knee. Static balance was assessed using four-stage balance test. Dynamic balance was assessed using the Timed Up and Go test.

RESULTS:
Statistical analysis was performed using Spearman's Correlational test to investigate the correlation between balance performance and knee body perception. The study included 73 patients within 45–80 years (59.4 ± 9.0). An overall strong positive correlation was obtained between balance performance and knee perception (r = 0.76, P = 0.00). Based on the OA grades, this correlation was moderate (r = 0.62, P = 0.00) in mild OA, moderate (r = 0.47, P = 0.05) in moderate OA, and strong (r = 0.71, P = 0.02) in severe OA.

CONCLUSION:
In knee OA patients, positive correlation exists between balance performance and knee body perception. As the severity of the disease increases, there is more impairment in balance and body perception. This affects the physical performance, quality of life in knee OA patients.

Published: February 2022

CONTEXT:
COVID-19 outbreak has disrupted the lives of many people. The lockdown imposed from March 2020 in India, a necessary step taken for containment of the coronavirus infection, also had its effect on students' social and academic life. Along with many individuals, the student population has also gone through a range of psychological and emotional reactions due to uncertainty, lack of financial stability, academic delay, lack of physical contact with family members, friends, and constant overloading of information via social media.

AIMS:
The study was conducted to determine the effects of the COVID-19 crisis on the mental health of physiotherapy students.

SETTINGS:
Community (online).

DESIGN:
Survey study-Questionnaire based.

SUBJECT AND METHODS:
An online survey was conducted via Google forms consisting of demographic data and Depression Anxiety Stress Scale (DASS)-21 questionnaire (a shorter version of DASS41) having seven questions each subscale, i.e., depression, anxiety, and stress. The data were collected from June 22, 2020, to July 3, 2020.

STATISTICAL ANALYSIS USED:
Descriptive analysis of the data obtained was performed.

RESULTS:
A total of 275 physiotherapy students participated in the study. About 34.6% of students were found to have depression, 31.1% have anxiety, and 16% have stress in the range of mild, moderate, severe, and extremely severe. Majority were in mild category of depression, anxiety, and stress. 4th-year students were found to be more affected as compared to other students.

CONCLUSIONS:
COVID-19 crisis has affected the mental health of students.
Translation of shoulder pain and disability index in Gujarati language and analysis of its psychometric properties in persons with shoulder pain
Authors: Bhatt Vidhi Paras , Shah Nehal , Bhrambhatt Krishna M. , Kapadia Dharti 
Published: February 2022

BACKGROUND:
Shoulder pain and disability index (SPADI) is a joint specific tool that helps to estimate the pain and disability in persons with shoulder pain. It is a self-administered index consisting of 13 items divided into two subscales: pain and disability. The study aims to find inter- and intra-rater reliability and concurrent validity of Gujarati version of SPADI (SPADI-G) in persons with shoulder pain in Gujarati population. SPADI-G can prove to be helpful in objectively defining the pain and disability in persons with shoulder pain.

MATERIALS AND METHODS:
A prior permission was taken from original author for translation of SPADI into Gujarati language. The translation procedure was carried out according to the guidelines provided by the WHO with forward and backward translation. The psychometric properties were analyzed in 20 persons (mean age of 52.65 ± 7.76) with different shoulder pathologies. Informed oral consent was taken from persons before the study. The validity was obtained by correlating SPADI-G and visual analog scale (VAS). The intrarater reliability was established by test–retest method within a span of 2 days. The questionnaire was again administered after 1 week by two different investigators to test the interrater reliability.

RESULTS:
The concurrent validity was established with a positive correlation with moderate strength between SPADI-G and VAS (Pearson's coefficient of correlation: r = 0.587, P < 0.01). The intrarater reliability was found between 0.853 and 0.977 (intraclass correlation coefficient [ICC] = 0.943) and interrater reliability was found between 0.914 and 0.983 (ICC = 0. 959). There was a high internal consistency with Cronbach's alpha = 0.967. The Bland–Altman plot analysis was performed for SPADI-G scores in between the two raters, which showed agreement between the two scores within the limits of agreement with 95% confidence interval. The linear regression showed no proportional bias.

CONCLUSION:
The results show good validity with moderate correlation between VAS and SPADI-G and excellent inter- and intra-rater reliability for SPADI-G in persons with shoulder pain.

ABSTRACT.
There is a scarcity of population-level data of pediatric COVID-19 infection from Southeast Asia. This study aims to describe and compare epidemiological, clinical, laboratory and outcome data among pediatric COVID-19 cases versus controls in two neighboring countries, Singapore and Malaysia. We used a test-negative case–control study design recruiting all suspected COVID-19 cases (defined by either clinical or epidemiological criteria) from January 2020 to March 2021 admitted to two main pediatric centers in Singapore and Malaysia. Data were collected using a standardized registry (Pediatric Acute and Critical Care COVID-19 Registry of Asia). The primary outcome was laboratory-confirmed COVID-19. Univariate and multivariable logistic regression analysis was used to determine factors associated with COVID-19. This study included 923 children with median age of 4 (interquartile range 2–9) years. Of these, 35.3% were COVID-19 cases. Children with COVID-19 were more likely to be asymptomatic compared with controls (49.4 versus 18.6%; P < 0.0001). They were also less likely to develop respiratory complications, such as bronchitis or pneumonia, or organ dysfunction. Four (1.2%) of our COVID-19 patients required respiratory support compared with 14.2% of controls needing respiratory support. COVID-19 cases tended to have lower neutrophil count but higher hemoglobin compared with controls. There were no reported deaths of COVID-19 infection; in contrast, 0.7% of the control group died. In the multivariable analysis, older age, travel history, and close contact with an infected household member were associated with COVID-19 infection. This study shows that the majority of pediatric COVID-19 cases were of lesser severity compared with other community acquired respiratory infections.
SPAG9 promotes the migration and invasion of melanoma cells by regulating the MAPK pathway
Authors: Liu Yongjun , Zhu Xuefeng , You Xiaoen , Kang Runfang 
Published: February 2022

Purpose: To determine the regulatory role of sperm-associated antigen 9 (SPAG9) in melanoma cell growth.
Methods: Immunohistochemical analysis was performed to investigate SPAG9 expression in melanoma tissues. Western blot was used to evaluate SPAG9 expression in melanoma tissues and cells. Melanoma cells were transfected with an siRNA targeting SPAG9 or a SPAG9 overexpression vector. Cell migration and invasion were examined by wound healing and transwell assays. The effects of SPAG9 on the epithelial-mesenchymal transition and mitogen-activated protein kinase (MAPK) pathway in melanoma cells were assessed by western blot.
Results: SPAG9 expression was enhanced in melanoma tissues and cells. SiRNA-mediated silencing of SPAG9 repressed melanoma cell migration and invasion, and SPAG9 overexpression contributed to melanoma cell metastasis. In melanoma cells transfected with siRNA-SPAG9, E-cadherin expression decreased while vimentin and matrix metalloproteinase (MMP)-2/9 expression increased. However, ectopic expression of SPAG9 reversed this expression of E-cadherin, vimentin, and MMP-2/9. Silencing of SPAG9 decreased the phosphorylation of MAPKs, including p-p38, p-ERK and p-JNK, in melanoma cells. SPAG9 overexpression upregulated phosphorylation of MAPKs.
Conclusion: SPAG9 promotes the migration and invasion of melanoma cells by activating the MAPK pathway.
40Ar/39Ar age, lithogeochemistry and petrographic studies of the Cretaceous Alkaline Marapicu Intrusion, Rio de Janeiro, Brazil

Published: February 2022

The Marapicu Alkaline Massif is an intrusion into the Marapicu-Gericinó-Mendanha Igneous Complex that is part of the Cretaceous Poços de Caldas-Cabo Frio magmatic lineament located in the Southeastern region of Brazil. Nepheline syenites and phonolites are the most abundant rocks in the massif that also include syenites forming an alkaline series SiO2- undersatured. Chemically this series is predominantly metaluminous and to a lesser extent peralkaline. This series presents both potassic and sodic suites being the first one in greater content. The data show that both basic and intermediary rocks with parental composition sampled in this area have no genetic relationship with the other rocks of the body. Geochemistry data shows that evolution processes involved fractional crystallization with or without continental crust assimilation and also indicates that this alkaline magma was generating from an enriched mantle source. The 40Ar/39Ar age of hornblende (extracted of nepheline syenite) from Marapicu massif is 80.46 ± 0.58 Ma, which it is contrasting, with the idea of age decrease of the hotspot track from west to east on the Poços de Caldas-Cabo Frio magmatic lineament.

Published: February 2022

Este estudo comparou a produção pesqueira e a composição de pescado de diferentes tipos de currais, localizados em áreas costeira e fluvial na costa norte do Brasil. Por meio de entrevistas e de observação participativa, monitorou-se a produção de 12 currais, dos tipos coração, enfia e cachimbo. As amostragens foram realizadas a cada despesca por três dias consecutivos, durante a lua nova, nos meses de junho a agosto de 2012. Foram capturados 4.274 indivíduos, pertencentes a nove ordens, 20 famílias e 43 espécies de peixes. A ordem Perciformes apresentou o maior número de famílias (50%), de espécies (44%) e de indivíduos (75%). A família Ariidae foi a mais abundante em número de espécies (23%). Macrodon ancylodon (Bloch & Schneider, 1801) (51%), Sciades couma (Valenciennes, 1840) (9%), Cynoscion virescens (Cuvier, 1830) (9%) e Mugil incilis Hancock, 1830 (4%) foram as espécies mais representadas. A comparação da captura entre currais e ambientes indicou que a produção total diferiu entre os tipos de currais associados à sua localidade. O tipo coração foi mais produtivo na área costeira, em relação à área fluvial. Apesar do aumento gradual na produção total entre os meses de junho a julho, a captura na área fluvial evidenciou uma produção decrescente nesses meses

Diversidade de aranhas em ecossistemas de manguezal e de floresta de terra firme na Reserva Extrativista Marinha de Soure, ilha de Marajó, Pará, Brasil
Authors: Silva Junior Claudio de Jesus , Saturnino Regiane 
Published: February 2022

Este artigo caracteriza a araneofauna de manguezal e de floresta de terra firme da Reserva Extrativista Marinha de Soure, localizada em Soure, ilha de Marajó, Pará. Ele constitui o primeiro inventário de aranhas para a região, para o qual foram empregados três métodos de coleta, aplicados em dez pontos da região. Foram registrados 2.629 indivíduos, sendo 2.075 jovens e 554 adultos, 121 espécies/morfoespécies e 30 famílias. Do total de adultos, 296 (53,4%) foram coletados nas áreas de manguezal, enquanto 258 (46,6%) em floresta de terra firme. As famílias mais abundantes foram Araneidae (26,7%), Theridiidae (16,4%) e Trechaleidae (11,9%); as que apresentaram maior riqueza foram Araneidae (31 spp.), Salticidae (25 spp.) e Theridiidae (14 spp.). A riqueza observada foi de 69 espécies para o manguezal e 74 para a terra firme, sendo que 47 e 52 delas foram exclusivas de cada ecossistema, respectivamente. Foram registradas aranhas pertencentes a dez diferentes guildas, sendo que oito estavam em áreas de manguezal e dez em terra firme. Inventários com maior esforço amostral devem ser realizados para aumentar a representatividade da diversidade da reserva. Contudo, o grande número de espécies exclusivas indica alta complementaridade entre os dois ecossistemas, sugerindo a importância da conservação das manchas de habitat existentes na região.
Províncias Ígneas Gigantes e o reposicionamento dos proto-crátons sul-americanos em Columbia, na transição Orosiriano-Estateriano
Authors: Chaves Alexandre De Oliveira , Fonseca Wellison Martins 
Published: February 2022

Sob a luz dos processos tectônicos intraplaca e orogênicos vigentes durante a transição Orosiriano (2,05-1,80 Ga) – Estateriano (1,80-1,60 Ga), é apresentada, neste artigo, uma tentativa de reposicionamento dos proto-crátons sul-americanos Amazônico, São Francisco, Rio de la Plata e São Luís, no supercontinente Columbia, utilizando dados geológicos, geocronológicos e paleomagnéticos de Províncias Ígneas Gigantes (Large Igneous Provinces – LIP) e de Províncias Ígneas Gigantes Silícicas (Silicic Large Igneous Provinces – SLIP) disponíveis na literatura. Uma possível junção tríplice pode ser reconstruída, dentro da qual as respectivas LIP e SLIP são acomodadas no tempo e no espaço, com o proto-cráton Rio de la Plata virado de cabeça para baixo e posicionado entre o proto-cráton Amazônico e o bloco Báltica e, ainda, por meio de rotação no sentido horário de cerca de 90 graus do proto-cráton Amazônico em relação à sua posição atual, colocando-o lado a lado com o proto-cráton São Francisco. Um cenário geológico coerente com a Tafrogênese do Estateriano, que marca o início da quebra de Columbia, é remontado a partir do ensaio geotectônico aqui proposto.

Published: February 2022

O presente estudo teve como objetivo realizar o inventário das espécies do gênero Pinnularia, ao longo dos cursos superior e médio do rio Negro, incluindo dois rios tributários e onze igarapés, bem como avaliar a distribuição dos táxons nos ambientes amostrados. A pesquisa baseou-se em análise de lâminas permanentes de amostras planctônicas e perifíticas. Os resultados revelaram a presença de 53 táxons específicos e infraespecíficos. Pinnularia romanorum Metzeltin & Lange-Bertalot é registrada pela primeira vez para a Amazônia brasileira. A maior porcentagem foi de organismos raros (58,5%), seguida de esporádicos (32,07%) e frequentes (9,43%). O rio Negro apresentou maior riqueza específica em relação aos seus tributários. A diversidade beta demonstrou que a distribuição dos táxons na bacia do rio Negro foi homogênea (ß-1 = 19,07). A homogeneidade na distribuição dos táxons deve-se, provavelmente, ao período de enchente, no qual foram realizadas as amostragens, quando o rio transborda do seu leito e invade as áreas marginais, inundando-as em diferentes graus de intensidade. Este fluxo torna os ambientes mais ricos em microalgas e mais homogêneos.

Published: February 2022

A configuração de zonas permoporosas na porção sudoeste do Sistema Aquífero Boa Vista, no estado de Roraima, localizada no campus Paricarana, da Universidade Federal de Roraima, a partir da execução de vinte sondagens elétricas verticais, distinguiu eletricamente o comportamento do conteúdo litológico da Formação Boa Vista, amplamente distribuído na área (argilitos com ρa < 1.000 Ω.m, arenitos com 1.000 < ρa < 20.000 Ω.m e concreções lateríticas ferruginosas com ρa > 50.000 Ω.m). Estes resultados permitiram identificar sete padrões geoelétricos, entre os quais os padrões 1 e 3 (SW e WNW) configuraram as melhores zonas permoporosas da área, devido aos indícios de concentrações lateríticas porosas, que são circundadas por materiais argilosos de regiões com evidências quanto à presença de paleolagos e de lagos sazonais, extremamente arenosos. Os padrões 2, 4 e 6 (NW, centro-oeste, N e NE) representaram as zonas de moderada expressividade, pois indicaram presença de materiais areno-argilosos com até 10 m de profundidade. Os padrões 5 e 7, por sua vez, embora estejam amplamente distribuídos no campus (NW, NE, SE e SW), configuraram zonas permoporosas com pouco potencial aquífero, pois apontaram para maior predominância de materiais argilosos, os quais podem funcionar como camada selante, protegendo a possível zona detentora de água da contaminação superficial.

Published: February 2022

Our objective was to inventory the flora of aquatic macrophytes and their life forms, and to determine the species similarity in different water bodies. Sampling of the vegetation was carried out in 333 plots of 0.5 x 0.5 m along ten transect lines on a boat to best cover the studied areas. Poaceae (18.9%), Cyperaceae (9.4%), Fabaceae, Onagraceae, and Pontederiaceae (7.5% each) were the most represented families. Emergent (56.6%), free floating (20.8%), rooted floating (18.9%), and amphibious (13.2%) were the most common life forms. We observed dissimilarity between most sampled points. We conclude from the inventory of aquatic macrophytes that the most prevalent species are common to other similar physiognomies in the Pantanal and the prevalent life forms corroborate the importance of flood in this environment, since they are typical of plants adapted to the flooded and dry transition. Even though the species richness is comparable to other areas, the plant communities inventoried separately are heterogeneous and respond in distinct ways to local environmental conditions.

Published: February 2022

O objetivo do presente estudo foi verificar a existência de variação na estrutura populacional de Albizia niopoides (Benth.) Burkart e de Mimosa hexandra Micheli entre e dentro de remanescentes de Chaco florestado. O estudo foi realizado em dois remanescentes no município de Porto Murtinho, Mato Grosso do Sul, Brasil, a partir de duas parcelas de 2.500 m2 em cada remanescente. Para a análise da estrutura populacional, foram registrados a altura e o diâmetro de todos os indivíduos das espécies em estudo. Foi observada diferença na estrutura populacional entre e dentro dos remanescentes avaliados das duas espécies, resultante principalmente da altura dos indivíduos. A prevalência de indivíduos com menor classe de diâmetro evidenciou que a população é autorregenerativa e o ambiente é heterogêneo, devido provavelmente à inundação sazonal, ao relevo com murundus e também à menor luminosidade, fator que contribui para a estruturação da população das duas espécies, uma vez que se trata de uma vegetação florestal.
