Study of retinal nerve fiber layer thickness in diabetic patients using optical coherence tomography

Purpose: This study aimed to assess and compare the changes in peripapillary retinal nerve fiber layer (RNFL) thickness in nondiabetics and diabetics with various stages of diabetic retinopathy (DR). Methods: The study subjects were divided into four groups based on their diabetic status and findings, namely, controls (normal subjects without diabetes [NDM]), diabetics without retinopathy (NDR), nonproliferative DR (NPDR), and proliferative DR (PDR). Peripapillary RNFL thickness was assessed using optical coherence tomography. One?way analysis of variance (ANOVA) with the post?Tukey HSD test was done to compare RNFL thickness in different groups. The Pearson coefficient was used to determine the correlation. Results: There was statistically significant difference in measured average RNFL (F = 14.8000, P < 0.05), superior RNFL (F = 11.7768, P < 0.05), inferior RNFL (F = 12.9639, P < 0.05), nasal RNFL (F = 12.2134, P < 0.05), and temporal RNFL (F = 4.2668, P < 0.05) across the different study groups. Pairwise comparison showed that there was a statistically significant difference in RNFL measured (average and all quadrants) in patients with DR (NPDR and PDR) and the NDM control group (P < 0.05). In diabetics without retinopathy, the RNFL measured was reduced compared to controls, but it was statistically significant only in the superior quadrant (P < 0.05). Average RNFL and RNFL in all quadrants showed a small negative correlation with the severity of DR and it was statistically significant (P < 0.001). Conclusion: In our study, peripapillary RNFL thickness was reduced in diabetic retinopathy compared to normal controls and the thinning increased with the severity of DR. This was evident in the superior quadrant even before the fundus signs of DR set in

Overview of systematic reviews/Meta-analysis of Xingnaojing Injection in treatment of intracerebral hemorrhage / 中国中药杂志

To overview of systematic reviews/Meta-analysis of Xingnaojing Injection(XNJ) in the treatment of intracerebral hemorrhage(ICH). The systematic reviews concerning XNJ in the treatment of ICH were retrieved from four Chinese databases, four English databases, Chinese Clinical Trial Registry and ClinicalTrail.gov, with the retrieval time set from their inception to September 2020. Following the independent screening and data extraction by two researchers, a measurement tool to assess systematic evaluation 2(AMSTAR 2) and grades of recommendation, assessment, development and evaluation(GRADE) system were used to evaluate the metho-dological, reporting and evidence qualities of the 10 included systematic reviews. The results showed that XNJ was superior to the wes-tern medicine or conventional treatment in improving the effective rate and National Institutes of Health stroke scale(NIHSS) score, Barthel index(BI), and Glasgow coma scale(GCS) score and Chinese stroke scale(CSS) score, and reducing the mortality and cerebral hematoma volume, without inducing obvious adverse reactions. In general, the methodological, reporting and evidence qualities of the 10 included systematic reviews were poor. The AMSTAR 2 scores showed that key items No. 2 and No. 16 failed to meet the stan-dard, resulting in poor methodological quality. There was only one outcome indicator graded by GRADE as intermediate quality, 43% indicators as low quality, 42% indicators as extremely low quality, and none as high quality. These available evidences have suggested that the methodological, reporting and evidence qualities of the systematic evaluation concerning XNJ for the treatment of ICH need to be improved. Most evidences support that XNJ was better than the western medicine or conventional treatment in the treatment of ICH, but the methodological quality and the reliability of outcome indicators in relevant systematic review were low. More high-quality studies are still required for further verification.

Abstract In the livestock systems of the Colombian high tropics, the seasonality of forage, and the energy deficit of the diets of cattle, are the greatest limitations to the potential of animal productivity. The objective of the study was to evaluate the concentration of soluble solids in two perennial shrub species (Tithonia diversifolia and Sambucus nigra, age: 60 days (d) and two ryegrass varieties (Lolium perenne) Columbia and Samson (age: 32 d) at the Obonuco Research Center of Agrosavia (Pasto-Nariño). The data were analyzed under a completely randomized design with a repeated measurement arrangement taking as an experimental unit the evaluation plots in both shrubs and grasses. Soluble solids concentration (%Ss), nutritional composition and biomass production were measured in three time periods (7:30 a.m., 11:30 a.m. and 3:00 p.m.). The analysis was performed using R V. 3.5.1 software through ANAVA and mean comparison tests (tukey<0.05). Data indicated higher concentration (p<0.05) of Ss for S.n (12.5%) compared to the other species. The highest numerical values of Ss in all species were presented at 3:00pm and the lowest at 7:30 a.m. At a nutritional level there was a difference (p<0.05) for non-structural carbohydrates (NSC), being higher for S.n (29.5%) than T.d (25.4%). The production of biomass (MS/t/ha/year), was higher (p<0.05) for T.d (22.8 t) with respect to S.n (11.4 t). The results obtained from Ss for the fodder resources evaluated are of great importance for estimating the energy value of these fodder products in animal feed.

A study of correlation of antenatal uterine scar thickness by transabdominal ultrasound with intraoperative lower uterine segment scar grading in elective repeat cesarean delivery

Background: Caesarean section (CS) is the most common obstetric surgery performed world-wide. The objective of this study was to correlate the antenatal sonographic lower uterine segment (LUS) scar thickness in women with previous one cesarean section with intra operative LUS scar grading.Methods: A Prospective observational study was conducted from December 2014 to November 2015. In a tertiary care center. 200 pregnant women from ANC clinic with previous one LSCS were recruited. Transabdominal USG done between 36-38 weeks. LUS thickness was measured from bladder wall-myometrium interphase and myometrium-chorioamniotic membrane inter phase. Intraoperative grading of LUS scar was done. Based on grading of scar participants were assigned into scar dehiscence group (grade III and IV LUS scar) and non-dehiscence group (Grade I and II LUS scar).Results: Mean LUS thickness was 3.41±0.623 mm (range: 2-7 mm). Mean LUS thickness in the scar dehiscence group and non-dehiscence group was 2.98±0.55 mm and 3.48±0.60 mm (P value < 0.05) respectively. A cut off value of 3.5 mm was derived from ROC with sensitivity, specificity, positive and negative predictive value of 92.6%, 54.3%, 24.0%, 97.8%, respectively. The present study reported 27 (13.5%) cases of scar dehiscence.Conclusions: Ultra-sonographic evaluation of LUS thickness correlated significantly with intraoperative LUS appearance. USG evaluation of LUS can be used as a screening test to predict the LUS scar integrity. Risk of dehiscence is increased in women with thin LUS i.e. sonographic LUS thickness of < 3.5 mm and needs to be further evaluated. Women with previous one LSCS with thick LUS i.e. sonographic LUS thickness of > 3.5 mm, can be counselled regarding TOLAC if not contraindicated.

Body mass index profile among school children: an anthropometric study

Background: The study aimed to analyse the trends in the growth pattern of the children in the age group of 3-21 years of both boys and girls using body mass index (BMI). The study also compared the BMI of the sample with the WHO norms and the group average.Methods: A study was conducted in India covering 1728 children 849 boys and 879 girls from LKG grade to +2 grades in the age group of 3-21 years. BMI grades were computed as per WHO 2006 standards (underweight- <18.50, normal- 18.50-24.99, overweight- >25.00 and obese- >30.00). Results were analyzed using percentage and ANOVA.Results: The data shows that 88.9% of children in the age group of 3-8 years are underweight and in 15-21 years of age children are relatively healthy, but are inclined to move to overweight (17.66%) and obesity (7.21%). More of boys (31%) tend to be underweight than girls. Age and gender were found to be significantly related to BMI. The average BMI of the sample group is above the national standards of WHO (World Health Organization) in all the three age groups. Boys are found to be on par with WHO norms while girls exceed the same. Majority of the sample were below the average denoting underweight.Conclusions: Age and gender was significantly related with BMI. Average BMI of the sample was on par with national standard of WHO. BMI was thus found to be an effective tool for predicting the well-being of school children.

Disability in New Leprosy Cases - Magnitude, Pattern and Associated Factors: A Cross Sectional Study in a Subdivision of Darjeeling District, West Bengal

Leprosy is an infectious disease, which may lead to disability before, during or after treatment. Leprosy is associated with social stigma and discrimination because of disability and disfigurement and recognized as a disease of major public health significance. As factors associated with occurrence and management of disabilities may vary from area to area, it is important to generate this information in affected populations. This study has been carried out to determine the extent and pattern of disabilities among newly diagnosed leprosy cases, factors associated with disability, provision and utilization of disability preventive services. This cross-sectional study was conducted in Siliguri subdivision of Darjeeling district, West Bengal. All newly diagnosed and registered leprosy cases in a reference year (April 2013 - March 2014) were included. Detailed medical examination and interviews was carried out to assess the disability and to study the relevant aspects. The entire collected data was analysed using SPSS software and chi-square, binary logistic regression were applied to test association between disability and other epidemiological correlates. It was observed that all the disabilities were in multibacillary (MB) cases only. Child leprosy rates of 5.5% appears to be promising statistics. Among 110 new leprosy cases studied, overall proportion of disability was 15.5%; grade 1 and grade 2 disabilities were 9.1% and 6.4% respectively. Hand was the commonest site of involvement, whereas grade 2 disability was highest in feet (2.7%). Disability status was found to be significantly associated with number of nerve involvement and history of treatment interruption. Utilization of disability preventive services was found very poor. Significantly the proportion of disability was highest among leprosy cases aged 60 years or more (37.5%). As no disability was noted in patients below 15 years, march towards achieving one of the targets of Global Leprosy Strategy 2016-20 appears to be closing to goal. Though the situation may be better comparably to some other parts of country, yet the overall proportion of disabilities as well as grade 1 and grade 2 disabilities among newly diagnosed leprosy cases is unacceptably high in the studied area. Community based studies and appropriate interventions can help in achieving the targets pertaining to leprosy situation in general and access to quality services in particular

Prevalence of anemia in school children in the age group of 8 to 14 years in Thiruvarur, Tamilnadu, India

Background: Iron deficiency is responsible for most of the nutritional anemia. Hemoglobin concentration is a reliable indicator of anemia at the population level, as opposed to clinical measures which are subjective and therefore have more room for error. Measuring Hemoglobin concentration is relatively easy and inexpensive, and this measurement is frequently used as a proxy indicator of iron deficiency. To study the association of certain risk factors with the prevalence of anemia in school children in the age group of 8-14 years.Methods: The study was conducted from April 2017 to March 2018 in Department of Paediatrics, Government Thiruvarur Medical College, Thiruvarur. The study population consisted of school children in the age group of 8 to 14 years fulfilling the inclusion and exclusion criteria. The sample size was 250. Complete hematological investigations was done to each child for differential diagnosis of anemia.Results: Majority of the children studied had a normal BMI 38.4% (n=96), 16.8% (n=42) were classified as overweight, 9.2% (n=23) were classified as obese. 22.8% (n=57) were classified as having thinness. 12.8% (n=32) were classified as having severe thinness. Of the 132 children with anemia, majority had mild anemia 64.39% (n=85) followed by moderate 28.03% (n=37) and severe anemia 7.58% (n=10). Of the 132 children with anemia, majority had mild anemia 64.39% (n=85) followed by moderate 28.03% (n=37) and severe anemia 7.58% (n=10).Conclusions: The prevalence of anemia was significantly higher in female children (64.91%) compared to male children (42.65%). The prevalence of anemia is highest in children with severe thinness (78.13%) followed by children with obesity (73.91%). The most common type of anemia in our study was iron deficiency anemia. Majority of the children were suffering from anemia of mild severity. There was no statistically significant correlation between the prevalence of anemia in children and age and socioeconomic status.

But there is no difference in serum HBsAg levels normalized to HPCV between HBeAg-positive and HBeAg-negative CHB.

Application of quality constant method in evaluation of Ligusticum chuanxiong pieces / 中国中药杂志

The method of classifying the quality grade of traditional Chinese medicine slices with cross section model quality constant was applied to the grade evaluation of Ligusticum chuanxiong pieces,and a reasonable grade standard of L. chuanxiong pieces was established. The purpose is to classify the 15 batches of L. chuanxiong pieces by combining the advantages of traditional grading with modern quality control indicators. By measuring the natural morphological parameters,processing parameters and the intrinsic content of ferulic acid,an important active ingredient,of the 15 batches of L. chuanxiong pieces collected from different manufacturers and different batches of different medicinal materials markets,we can synthesize the results. The mass constants and percentage mass constants are calculated and analyzed based on the above data. The results showed that the quality constants of 15 batches of L. chuanxiong pieces collected ranged from 0.53-3.00; if the percentage mass constants were more than 80%,50%-80% was second-class pieces,and the rest were third-class pieces,the evaluation results were as follows: the quality constants of first-class L. chuanxiong pieces were more than 2.40,the quality constants of second-class L. chuanxiong pieces should be 1.70-2.40,and the quality constants of third-class L. chuanxiong pieces should be less than 1.70. In this paper,the method of dividing the quality constants of the top blade model into different grades is further applied and practiced,which proves that the method is scientific,reasonable and multi-adaptable. At the same time,it enriches the research data of the grade evaluation of L. chuanxiong pieces,provides a useful reference for the promotion of the grade evaluation of L. chuanxiong pieces,and lays an experimental foundation for the next research of the subject group.

Grade evaluation of Gardeniae Fructus based on quality constant method / 中国中药杂志

Grade evaluation method of quality constant is a kind of grading method for Chinese medicinal materials and decoction pieces,combining the external morphological index and internal content index. This method was used in this paper for grade evaluation of Gardeniae Fructus. By measuring the morphological and content indexes of 14 batches of Gardeniae Fructus,a method for calculating the quality constant of fruits was established,and the grade evaluation criteria were formed. At the same time,the NO inhibition effect of different grades of Gardeniae Fructus samples on RAW264. 7 cells induced by LPS was determined to investigate the relationship between the quality grade and pharmacodynamics of decoction pieces. The results showed that the quality constants of Gardeniae Fructus decoction piece samples ranged from 1. 46 to 4. 42. If the percentage quality constant ≥80% was classified into first-class,50%-80%as second-class and the rest as third-class,the quality constant was ≥3. 54 for first-class,2. 21-3. 54 for second-class and <2. 21 for third-class Gardeniae Fructus decoction pieces. The pharmacodynamic results showed that the pharmacodynamic intensity was positively correlated with the grade,which also proved the rationality of the grade evaluation method of quality constant.

Application of relative quality constant in grades evaluation of bran stir-baked Aurantii Fructus / 中国中药杂志

The specifications of Chinese herbal medicines naturally form and exist in the circulation and use of Chinese herbal medicines.Buyers and sellers negotiate price by quality. With the increasing demand for public health care,the cultivation,processing methods and circulation of Chinese herbal medicines have changed. Under the mode of pursuing output and short-term benefits,the traditional grade evaluation method has been difficult to apply to the current quality status of the pieces. Bran stir-baked Aurantii Fructus is a genuine medicinal material in Jiangxi province. It is widely used,but the quality level of bran stir-baked Aurantii Fructus on the market is not uniform. Quality constant method was used in this paper for grading the Chinese herbal slices of bran stir-baked Aurantii Fructus. Sixteen batches of different quality samples were collected and tested,and finally,eleven qualified batches of them were chosen as researcher objects. The results showed that the relative quality constant ranged from 2. 52 to 5. 60. The relative quality constant was ≥4. 48 for first grade bran stir-baked Aurantii Fructus,2. 80-4. 48 for the second grade pieces,and <2. 80 for the third grade pieces. The grades evaluation method for bran stir-baked Aurantii Fructus established in this paper included both appearance and index composition. The results were objective,accurate,quantitative,applicable,and the method was simple to operate and easy to popularize. This study showed that the quality constant method could be applied to the grade evaluation of bran stir-baked Aurantii Fructus,providing a reference for the grade evaluation of fruit-type decoction pieces.

Therefore,grade evaluation of Chinese medicine slices( GECMS) is highly valued and has grown rapidly in the industry. In recent years,due to the comprehensive and measureable features,the Chinese medicine quality constant evaluation method has been gradually recognized and applied.The paper is to establish a method of grades evaluation of Glycyrrizae Radix et Rhizoma Praeparata Cum Melle( GRRPCM) based on the Chinese medicine quality constant. 20 batches of samples were collected from Chinese herbal slices enterprises and 14 batches of qualified samples were selected to determine their external morphological indexes and inner quality indexes,then their Chinese medicine quality constants were calculated and the grades were determined. The results revealed that the relative quality constant of these samples ranged from 0. 70 to 14. 08,with a percentage quality constant from 4. 95 to 100. 00. If these samples were divided into three grades: the relative quality constant shall be ≥11. 27 or percentage quality constant ≥80. 03 for the first grade; the relative quality constant shall be <11. 27 but ≥7. 04,or percentage quality constant <80. 03 and ≥49. 99 for the second grade; while for the third grade,the relative quality constant shall be <7. 04 or the percentage quality constant <49. 99. This research indicates that Chinese quality constant can be used to objectively grade the herbal slices,providing reference for grades standard development of complex processing slices. In addition,the connotation of GECMS that has evaluate the mass discrepancy is discussed for expanding application.

Grades evaluation of Scrophulariae Radix pieces based on quality constant / 中国中药杂志

The quality constant evaluation method was applied in the grade evaluation of Scrophulariae Radix pieces. Nineteen batches of Scrophulariae Radix were measured for the appearance index. Harpagide and harpagoside were taken as index components for the content determination. The traditional grading standard and the modern quality control index were combined to calculate the quality constant and grade Scrophulariae Radix pieces. The results showed that the quality constants ranged between 156. 75 and 491. 65; according to the percentage mass constants,more than 80% were graded as first-class pieces,50%-80% were graded as second-class pieces,and the rest were graded as third-class pieces. The quality constants of first-class Scrophulariae Radix were >393. 32,that of second-class Scrophulariae Radix was between 245. 83 and 393. 32,and that of third-class Scrophulariae Radix was < 245. 83. The study shows that this method can objectively,reasonably and effectively classify Scrophulariae Radix pieces,and further promote and apply the evaluation method of slice model quality constant to prove the rationality,scientificity and practicability.

Determination of seven ingredients of different grades Alismatis Rhizoma by QAMS method / 中国中药杂志

The present study is to establish a quantitative analysis of multi-components by single marker(QAMS) for determining contents of seven compositions in Alismatis Rhizoma, alismoxide, alisol C 23-acetate, alisol A, alismol, alisol B, alisol B 23-acetate and 11-deoxy-alisol B. Six relative correction factors(RCFs) of alismoxide, alisol C 23-acetate, alisol A, alismol, alisol B and 11-deoxy-alisol B were established in the UPLC method with alisol B 23-acetate as the internal standard, which was to calculate the mass fraction of each. The mass fraction of seven effective constituents in Alismatis Rhizoma was calculated by the external standard method(ESM) at the same time. Compared with the content results determined by the ESM and QAMS, the feasibility and accuracy of QAMS method were verified. Within the linear range, the RCFs of alismoxide, alisol C 23-acetate, alisol A, alismol, alisol B, 11-deoxy-alisol B were 0.946, 4.183, 0.915, 1.039, 0.923 and 1.244, respectively, with good repeatability in different experimental conditions. There was no significant difference between the QAMS method and ESM method. Then, QAMS method was applied to determination of the different degree Alismatis Rhizoma from different areas. As a result, the concentrations of 7 components have differences in different areas, but no significant differences in different grades. The QAMS method is feasible and accurate for the determination of the seven chemical compositions, and which can be used for quality control of Alismatis Rhizoma.

Application of Chinese medicine quality constant in grades evaluation of Moutan Cortex / 中国中药杂志

There are more and more literature reports about the application of Chinese medicine quality constant in the grading evaluation of Chinese medicine decoction pieces. Chinese medicine quality constant has particularly prominent advantages in comprehensive quantification,so it has become a new method and mode for grading Chinese medicine decoction pieces,highly recognized by the academic circle. In order to determine the effect of Chinese medicine quality constant,a method of grades evaluation for Moutan cortex was established in this paper. 15 batches of samples were collected from Chinese herbal slices enterprises to determine the external morphological indexes and inner quality indexes,calculate the Chinese medicine quality constant of Moutan cortex,and divide them into different grades. The results revealed that the range of the relative quality constant of these samples was from 0. 016 to 0. 060,with percentage quality constant from 27. 4 to 100. 0. If these samples were divided into three grades: the quality constant of the first grade should be ≥0. 048 or the percentage quality constant ≥80. 0; the quality constant of the second grade should be <0. 048 but ≥0. 030 or percentage quality constant <80. 0 and ≥50. 0; the quality constant of the third grade should be <0. 030 or the percentage quality constant <50. 0. This research indicated that Chinese quality constant can objectively divide grades of Moutan cortex decoction pieces,providing reference for formulating grades standards. It was also verified from the results that traditional quality evaluation of Moutan cortex was consistent with quality constant,and the connotation of percentage quality constant was elaborated as well. At the same time,it is suggested to establish a third-party Chinese medicine slices rating agency as soon as possible,which is to unify the terminology and provide rating services for the market.

Tradução e adaptação transcultural do instrumento Evaluation of Siderail Usage: estudo metodológico / Translation and cross-cultural adaptation of the Evaluation of Siderail Usage instrument: methodological study

Introdução: Grades são projetadas para serem usadas como dispositivos de segurança e estão fortemente associadas à prevenção de quedas entre adultos e idosos hospitalizados. Há evidências do uso indiscriminado de grades e seu uso inadvertido como forma de contenção, o que por sua vez pode comprometer a segurança, a dignidade e a autonomia do paciente. O Evaluation Of Siderail Usage foi um instrumento desenvolvido nos Estados Unidos para avaliar o uso de grades dividido em quatro partes. A primeira está relacionada com a preferência do residente; a segunda é a avaliação do risco de danos como queda, aprisionamento, contusões, lesões de pele. A terceira trata do risco de queda da cama e a quarta parte traz alternativas de intervenção e apresenta recomendações de prevenção e redução do uso de contenção/grades. Objetivos: Realizar a tradução e adaptação transculturamente do instrumento "Evaluation of Siderail Usage" para a língua portuguesa do Brasil e para o cenário hospitalar. Método: Trata-se de pesquisa metodológica. Antes de realizar a tradução e adaptação foi solicitada a autorização da autora, a Dra. Elizabeth Capezuti através de correio eletrônico. Foram utilizadas etapas da tradução e adaptação transcultural; tradução inicial; síntese das traduções; retrotradução e avaliação das versões por um comitê de juízes e pré-teste de acordo com Guillemin, Bombardier e Beaton (1993). Resultados: Na primeira etapa duas traduções foram realizadas; na segunda foi realizada uma reunião consensual com as duas tradutoras e as autoras do estudo para discutir as discrepâncias e uma versão síntese foi gerada; na terceira etapa, a versão síntese do instrumento foi retrotraduzida para o inglês por duas tradutoras para de verificar a equivalência com a versão original e não foram observadas discrepâncias significativas em relação ao instrumento original; na quarta etapa, um comitê de 25 juízes profissionais da área de saúde com expertise em estudos de validação ou em segurança do paciente analisaram a versão síntese, os resultados demostram um Indice de Validade de Conteudo (IVC) do instrumento de 0,97 e um Coeficiente de Validade de Conteúdo de 0,93. Na etapa de pré-teste 30 enfermeiros aplicaram a versão dos juízes em 57 pacientes hospitalizados, 29 do sexo masculino, idade entre 41 e 69 anos, com principais diagnósticos neuropatias e ortopédicos. Primeiramente os enfermeiros realizavam uma avaliação subjetiva da indicação do uso de grades laterais, seguida da indicação utilizando o instrumento traduzido. Os resultados da concordância entre as variáveis "Quantas grades o paciente prefere?" e "Avaliação subjetiva do enfermeiro em relação às grades"foi de 49,12%. O valor de concordância de Gwet foi de 0,316, p-valor < 0,001. Com relação à associação dos itens de avaliacao objetiva "Nenhuma grade lateral é indicada" e "Quantas grades o paciente prefere" foi significativa somente o item "Nenhuma grade lateral é indicada, paciente móvel"(0,018). Ao associar à "Avaliação subjetiva pelo enfermeiro do uso de grades" com a objetiva extraída das avaliações finais do instrumento obteve-se significância somente para o item "Nenhuma grade lateral é indicada, paciente móvel"(0,001). Ao associar o sexo dos pacientes com o item "Avaliação subjetiva pelo enfermeiro do uso de grades" o p-valor foi de 0,046, o uso de quatro grades ficou maior entre as mulheres e, nos homens foi de duas grades, ou seja, o número de grades se comportou de forma distinta entre os sexos. Ao relacionar o "Perfil dos enfermeiros" e "Avaliação subjetiva do enfermeiro em relação às grades" somente o item formação ­ especialização foi significativa (0,001). Sobre a análise de constructo observaram-se valores significativos (>0,70) que quando confrontados com os valores do índice de validade de conteúdo auxiliaram na decisão de retirada de itens para a construção de um instrumento final. Quanto aos resultados de praticabilidade o IVC médio foi de 94,2%entre os quatro itens e o índice de concordância foi de 0,181, com ligeira concordância, no entanto, significativo (0,006). Conclusão: Conclui-se a partir dos índices de concordância dos juízes e do pré-teste, que o instrumento teve seu conteúdo validado e contribuiu como uma ferramenta para avaliação de pacientes quanto ao uso de grades laterais do leito. Estima-se que o uso do instrumento as grades não sejam utilizadas como contenção mecânica, em pese o risco de segurança do paciente. Portanto Obteve-se como Produto a Tradução e Adaptação da Escala de Avaliação do Uso de Grades.

Introduction: The siderails are designed to be used as safety devices and are strongly associated with fall prevention among hospitalized adults and seniors. There is evidence of the indiscrimninate use of siderail and their inadvertently use as a form of containment, wich in turn may compromise patient safety, dignity and autonomy. An assessment is necessary to determine the need or removal of siderail in the bed. The Evaluation of Siderail Usage was an instrument developed in the United States to evaluate the use of siderail and is divided in four parts. The first is related to the preference of the resident; the second is the assessment of risk of fall, entrapment, bruises, skin lesions.The third deals with the risk of bed fall and the fourth part provides alternatives for intervention and presents recommendations for prevention and reduction of the use of restraint / siderails. Objectives: Carry out a review of the literature on siderail evaluation instruments and To carry out a transcultural translation and adaptation of the instrument "Evaluation of Siderail Use" for Brazilian Portuguese and for the hospital scenario. Method: This is a methodological research. Before undertaking a translation and adaptation, an authorization was requested from the author, Dr.Capezuti Elizabeth. through electronic mail. The steps of translation and adaptation to the culture were used; initial translation; Synthesis of translations; Retrotranslation and evaluation of the versions by a committee of judges and pre-test according to Guillemin, Bombardier and Beaton (1993). Results: In the first stage two translations of the instrument were carried out; in the last meeting was consensus with the two translators and as study authors to resolve how discrepancies and synthetic version was generated; in the third stage, the original version of the article was retrotranslated for english twice to verify equivalence with the original version and did not present discrepancies in relation to the original instrument; in the fourth stage, a committee of judges analyzed a synthesis version and a back-translation regarding the equivalence between language and statistics and the English version of the English-language instrument that was used in the pretest. Conclusion: It can be considered as having access to the concordance index of judges, with which its instrument was validated and can be used as an evaluation tool for the use of degrees, since a decision making is not used without an individualized evaluation. Product: Review of literature on siderail evaluation instruments and Translation and translation and Adaptation of the "Evaluation of Siderail Usage" Scale.
