Comparative analysis of SARS-CoV-2 variants Alpha (B.1.1.7), Gamma (P.1), Zeta (P.2) and Delta (B.1.617.2) in Vero-E6 cells: ultrastructural characterization of cytopathology and replication kinetics

Abstract This study compares the effects of virus-cell interactions among SARS-CoV-2 variants of concern (VOCs) isolated in Brazil in 2021, hypothesizing a correlation between cellular alterations and mortality and between viral load and transmissibility. For this purpose, reference isolates of Alpha, Gamma, Zeta, and Delta variants were inoculated into monolayers of Vero-E6 cells. Viral RNA was quantified in cell supernatants by RT‒PCR, and infected cells were analyzed by Transmission Electron Microscopy (TEM) for qualitative and quantitative evaluation of cellular changes 24, 48, and 72 hours postinfection (hpi). Ultrastructural analyses showed that all variants of SARS-CoV-2 altered the structure and function of mitochondria, nucleus, and rough endoplasmic reticulum of cells. Monolayers infected with the Delta variant showed the highest number of modified cells and the greatest statistically significant differences compared to those of other variants. Viral particles were observed in the cytosol and the cell membrane in 100 % of the cells at 48 hpi. Alpha showed the highest mean particle diameter (79 nm), and Gamma and Delta were the smallest (75 nm). Alpha and Gamma had the highest particle frequency per field at 48 hpi, while the same was observed for Zeta and Delta at 72 hpi and 24 hpi, respectively. The cycle threshold of viral RNA varied among the target protein, VOC, and time of infection. The findings presented here demonstrate that all four VOCs evaluated caused ultrastructural changes in Vero-E6 cells, which were more prominent when infection occured with the Delta variant.

Métodos Estudo transversal integrado a uma coorte prospectiva, com coleta entre agosto de 2021 e fevereiro de 2022, baseado nas respostas de 304 mulheres que tiveram gestações e/ou partos durante o período pandêmico. Resultados Do total, 25,7% das entrevistadas tiveram COVID-19, com predomínio de diagnósticos no terceiro trimestre. Queixas de anosmia, fadiga e cefaleia prevaleceram como relacionados à infecção. As variáveis: utilizar o Sistema Único de Saúde para atendimento (p = 0,084); diabetes gestacional (p = 0,141); baixo peso de nascimento (p = 0,117); necessidade de internação em unidade neonatal (p = 0,120) foram inseridas no modelo de regressão por terem valores de p inferiores a 0,20. A variável referente ao tipo de parto (p=1,000) foi inserida no modelo por se tratar de uma variável de interesse e com descrição de relevância na literatura. A prematuridade foi a única variável que apresentou associação estatística com a infecção pelo SARS-CoV-2 durante a gestação (p = 0,008) na análise bivariada, explicando o desfecho da infecção na gestação (<0,001), comprovado no modelo de Regressão Robusta de Poisson. Conclusão Observou-se alta prevalência de COVID-19 na amostra, com variação de sintomas e predomínio de partos operatórios. No entanto, a infecção pelo SARS-CoV-2 explicou apenas a maior ocorrência de nascimentos prematuros.

Se introdujo la variable relacionada al tipo de parto (p = 1,000) en el modelo por tratarse de una variable de interés y con descripción de relevancia en la literatura. La prematuridad fue la única variable que presentó asociación estadística con la infección por SARS-CoV-2 durante el embarazo (p = 0,008) en el análisis bivariado, lo que explica el desenlace de la infección en el embarazo (>0,001), comprobado en el modelo de regresión robusta de Poisson. Conclusión Se observó alta prevalencia de COVID-19 en la muestra, con variación de síntomas y predominio de partos operatorios. Sin embargo, la infección por SARS-CoV-2 explicó solamente la mayor incidencia de nacimientos prematuros.

Abstract Objective Identify the profile of births of pregnancies of women with internet access who were infected with SARS-CoV-2 and their outcomes. Methods Cross-sectional study integrated into a prospective cohort, with collection between August 2021 and February 2022, based on the responses of 304 women who had pregnancies and/or deliveries during the pandemic period. Results Of the total, 25.7% of the interviewees had COVID-19, with a predominance of diagnoses in the third quarter. Complaints of anosmia, fatigue and headache prevailed as related to the infection. The variables using the Unified Health System for care (p = 0.084); gestational diabetes (p = 0.141); low birth weight (p = 0.117); need for admission to a neonatal unit (p = 0.120) were included in the regression model because they had p values lower than 0.20. The variable referring to the type of delivery (p=1.000) was inserted in the model because it is a variable of interest and with a description of relevance in the literature. Prematurity was the only variable that was statistically associated with SARS-CoV-2 infection during pregnancy (p = 0.008) in the bivariate analysis, explaining the outcome of infection during pregnancy (<0.001), confirmed in the Poisson Robust Regression model. Conclusion There was a high prevalence of COVID-19 in the sample, with varying symptoms and a predominance of operative deliveries. However, SARS-CoV-2 infection only explained the higher occurrence of premature births.

Mesenteric cystic lymphangioma in adults: a rare entity presenting as acute abdomen - a report of two cases

ABSTRACT Lymphangiomas are rare benign tumors that mainly involve the head and neck region in pediatric patients. Lymphangiomas of the small bowel mesentery in adults are rarer. We present two cases of mesenteric lymphangioma with acute abdominal pain on presentation. Case 1: A 38-year-old female presented with abdominal pain, vomiting, fever, and difficult evacuation. On abdominal examination, she had an ill-defined, tender lump, and radiological findings raised a possibility of perforation peritonitis. Thus, exploratory laparotomy was planned. Per-operatively, a mesenteric mass was found, which, on histopathological evaluation, was found to be a mesenteric lymphangioma involving the bowel. Case 2: A 27-year-old male presented with abdominal pain and difficult evacuation. Radiological evaluation revealed a multilobulated lesion involving the mesentery and with differential diagnoses of mesenteric fibromatoses and inflammatory pseudotumor. Histopathological assessment of the resected mass revealed a lymphangioma that was limited to the mesentery. Owing to their rarity and non-specific presentation, mesenteric lymphangiomas are often misdiagnosed on clinical examination and imaging. Thus, histopathological examination is the gold standard to reach a definitive diagnosis.

Percepções das mães que são profissionais de saúde sobre as relações na unidade neonatal / Health professionals mothers' perceptions about relationships in the neonatal unit / Percepciones de las madres profesionales de la salud sobre las relaciones en la unidad neonatal

Objetivo: discutir as percepções das mães que são profissionais de saúde sobre as relações na unidade neonatal. Método: estudo qualitativo, apoiado no Interacionismo Simbólico, com 11 mães de recém-nascidos pré-termo que são profissionais da saúde. Após aprovação pelo Comitê de Ética em Pesquisa, os dados foram coletados de maio a outubro de 2021, por meio de entrevistas individuais, e submetidos à análise de conteúdo temática. Resultados: apesar de as mães serem profissionais da saúde, as relações na unidade neonatal foram difíceis, sofridas, desconfortantes e restritivas ao processo de 'ser e tornar-se mãe'. Estas desvelaram sentimentos de não pertencimento ao cuidado e de afastamento de suas crianças. Conclusão: as relações entre mães e profissionais da saúde atuantes na unidade neonatal estiveram marcadas por sofrimentos, limitações e desconfortos, sendo lacunares em processos colaborativos, na contramão do Cuidado Centrado na Família.

Objective: to discuss the perceptions of mothers who are health professionals about relationships in the neonatal unit. Method: a qualitative study, based on Symbolic Interactionism, with 11 mothers of preterm newborns who are health professionals. After approval by the Research Ethics Committee, data was collected from May yo October 2021, through individual interviews, and subjected to thematic content analysis. Results: despite the mothers being health professionals, relationships in the neonatal unit were difficult, painful, uncomfortable, and restrictive to the process of 'being and becoming a mother'. They revealed feelings of not belonging to care and of being away from their children. Conclusion: the relationships between mothers and health professionals working in the neonatal unit were marked by suffering, limitations, and discomfort, and were lacking in collaborative process, going against Family-Centered Care.

Children and adolescents with non-Hodgkin lymphoma in Brazil: A national survey identifies the challenges encountered and documents the diversity of care

ABSTRACT Introduction: Brazil has many inequities in the healthcare provided nationwide. Therefore, in order to access challenges in treatment, available resources and current practices, to identify barriers in delivering a good quality of care among Brazilian centers treating children and adolescents with Non-Hodgkin Lymphoma (NHL) and to generate a future prospective guideline, a customized online survey was distributed to pediatric hematologists and oncologists across the country. Results: A total of 97 surveys were completed (35% response rate), from 47 cities in all Brazilian regions and 79 units of care, with a median of 1 answer by the center (range 1 - 5). Most respondents work at an institution supported exclusively by public/philanthropic resources (58%), with an average of 5 to 9 new cases/year (49%), and 41% have 4 to 6 oncologists/centers. Additionally, 22% have no easy access to the intensive care unit, 26% have no access to Rasburicase, 28% have no access to Rituximabe as front-line therapy and 41% have unreliable methotrexate monitoring levels. Those differences cannot be explained thoroughly by regional wealth variances, nor by the financing model. Regarding the pathology service, 70% consider having reasonable quality assistance, but the timeframe to deliver diagnosis is satisfactory to 46%. There is no uniform management of care, with the current guideline from the Sociedade Brasileira de Oncologia Pediátrica being adopted by 54 to 59%, depending on the NHL subtype. Conclusion: This study provides insights into the heterogeneity of care among Brazilian centers. Recognizing those diversities will support the design of effective strategies and collaboration nationwide.

Refractive error changes and associated asthenopia observed after COVID-19 infection: Case reports from two continents

COVID-19 infection has been linked to various ocular complications and complaints, but not to refractive errors. In this case report, we present ethnically diverse patients who reported asthenopic symptoms shortly after recovering from COVID-19 infection. The hyperopic shift in the refractive error, post-COVID could indicate the ciliary body muscle’s inability to sustain accommodation, resulting in asthenopia. Hence, refractive errors should also be considered as a post-COVID complication, even if the magnitude is small, especially when patients have a headache and other asthenopic symptoms. Performing dynamic retinoscopy and cycloplegic refraction will also aid in the better management of these patients

Simplifying biometry in oil-filled eyes: A novel formula for axial length calculation in eyes with 1000 cSt silicone oil

Purpose: To derive a formula for accurate axial length (AL) assessment using routine ultrasound in silicone oil?filled eyes, where optical biometry is unavailable or not possible. Methods: This was a prospective, consecutive, nonrandomized study of 50 eyes of 50 patients conducted in a tertiary care hospital in North India. AL measurements were taken using both manual A?scan and IOL master, both in silicone oil?filled status and 3 weeks after silicone oil removal. A correction factor of 0.7 was used for AL adjustment in oil?filled eyes. The corrected AL (cAL) was compared with IOL master values in oil?filled eyes. Agreement analysis was carried out using Bland Altman plot. Linear regression analysis was done using uncorrected manual AL to find a new equation. Data was analyzed using Stata 14. A P value <0.05 was taken as significant. Results: The study included 40 males and 10 females, with an age range of 6–83 years (mean 41.9 years). The mean AL of the oil?filled eye as measured by manual A?scan was 31.76 mm ± 3.09 and by IOL master was 24.7 mm ± 1.74. Linear regression analysis was performed in randomly selected 35 eyes of the observed data to obtain a new equation: predicted AL (PAL) = 14 + 0.3 × manual AL. The mean difference between PAL and optically measured AL with silicone oil in situ was 0.98 ± 1.67. Conclusion: We propose a new formula for better prediction of the correct AL in silicone oil?filled eyes using ultrasound?based AL measurement.

Cognitive Function in Children With ?-Thalassemia Major

Objectives: To assess intelligence Quotient (IQ) in transfusion dependent ?-thalassemia major patients using Malin Intelligence Scale for Indian Children (MISIC) and to correlate verbal IQ (VIQ), performance IQ (PIQ) and full scale IQ (FSIQ) with serum ferritin levels and annual blood transfusion requirements. Methods: Cross-sectional study design, enrolling 100 patients of transfusion-dependent ?-thalassemia aged 6 years to 15 years 11 months. IQ was assessed using MISIC. Results: Mean (SD) full scale IQ was 95.96 (7.23). IQ was ‘average’ in most of the patients. There was a significant negative correlation of serum ferritin levels with object assembly (r=-0.215, P=0.034) component of PIQ; annual blood requirement with general comprehension component of VIQ (r=-0.275, P=0.006) and age at diagnosis with PIQ (r=-0.273, P=0.006). There was a significant linear correlation of PIQ (r=0.280, P=0.005) and FSIQ (r=0.274, P=0.006) with pre-transfusion hemoglobin. Conclusion: IQ correlates with age at diagnosis and average annual pre-transfusion hemoglobin. This highlights the importance of early diagnosis and maintenance of satisfactory hemoglobin levels

Reconstruction Plate Fracture: Mechanism and Recent Advances

Reconstruction plates with or without bone grafts are used to restore mandibular continuity, form and function following segmental resection of mandible. Fracture of reconstruction plate is observed in 2.9 % to 10% of cases reported in the literature excluding other complications. In this case, we report the fracture of stainless steel reconstruction plate used without bone graft and its management using locking reconstruction plate with non vascularised iliac crest graft following removal of the fractured plate. Review of literature describing incidence, pattern and causes of reconstruction plate fracture and its management is discussed.

Unraveling congenital ptosis with the aid of the pediatric perimeter device

Background: Ocular morbidity with an early onset can have a significant impact on the long-term development of an individual. Hence, careful assessment of visual functions early on is very important. However, testing infants always poses a challenge. Standard tools to assess infants’ visual acuity, ocular motility, and so on rely on the clinician’s quick subjective judgments of an infant’s looking behavior. Eye movements are usually observed from head rotations or spontaneous eye movements in infants. Judging eye movements in the presence of strabismus is even more challenging. Purpose: This video shows a 4-month-old infant’s viewing behavior captured during a visual field screening study. The recorded video aided in the examination of this infant that was referred to a tertiary eye care clinic. The additional information captured through the perimeter testing is discussed. Synopsis: The Pediatric Perimeter device was developed to address visual field extent and gaze reaction time assessment in the pediatric population. As a part of a large-scale screening study, infants’ visual fields were tested. During this screening, a 4-month-old infant presented with a ptosis in the left eye. The infant was consistently missing the light stimuli presented in the left upper quadrant in the binocular visual field testing. The infant was referred to a tertiary eye care center to a pediatric ophthalmologist for further examination. During clinical examination, the infant was suspected to either have congenital ptosis or monocular elevation deficit. But the diagnosis of the eye condition was unsure owing to the poor cooperation of the infant. With the aid of Pediatric Perimeter, the ocular motility was consistent with limitation of elevation in abduction, indicating a possible monocular elevation deficit with congenital ptosis. The infant was also noted to have Marcus Gunn jaw-winking phenomenon. The parents were assured and asked for a review in 3 months. In the subsequent follow-up, the Pediatric Perimeter testing was performed, and the recording showed a full extraocular motility in both eyes. Hence, the diagnosis was changed to only congenital ptosis. The probable explanation for missing the target in the left upper quadrant in the first visit is postulated further. The left upper quadrant is the superotemporal visual field of the left eye and the superonasal visual field of the right eye. As the left eye had ptosis, the superotemporal visual field could have been obstructed and hence the stimuli missed. The normative extent for the nasal and superior visual field is just about 30° for a 4-month-old infant. Hence, the right eye also perhaps missed the stimuli in its superonasal visual field extent. This video highlights the utility of the Pediatric Perimeter device in providing a magnified view of the infant’s face along with greater visibility of ocular features from the infrared video imaging. This can potentially help the clinician to easily observe different ocular/facial abnormalities such as extraocular motility disorders, lid functions, and in identifying unequal pupil size, media opacities, and nystagmus. Highlights: The presence of congenital ptosis in younger infants might predispose as superior visual field defect and could also masquerade as a limitation in elevation.

Desafios e potencialidades para a estruturação e o funcionamento dos Conselhos Locais de Saúde de Porto Alegre

O objetivo deste trabalho foi identificar a presença, bem como formas de atuação e funcionamento dos Conselhos Locais de Saúde (CLS) da cidade de Porto Alegre, visto o seu fomento como meta de gestão neste município, incluída por iniciativa do Conselho Municipal de Saúde. Metodologia: Trata-se de uma pesquisa exploratória e descritiva. Primeiramente, determinou-se a quantidade de CLS ativos. Em seguida, procurou-se agendar uma entrevista semiestruturada em grupo com os CLS encontrados, utilizando um instrumento desenvolvido e validado. Foi feita a estatística descritiva com a determinação de frequências. Resultados e Discussão: Foram encontrados 56 CLS ativos e 32 entrevistas foram realizadas. Os CLS têm uma Coordenação Local instituída e presente, com reuniões ocorrendo com pautas definidas, onde são discutidos assuntos de saúde e da vida comunitária, ainda que com baixa participação da comunidade. Os CLS usam a estrutura descentralizada de conselhos bem como outros canais como sistema de justiça e representantes políticos para encaminhar as demandas. Considerações finais: A inclusão de CLS como meta de gestão mostrou um resultado positivo no aumento dos CLS. Porém se deve pensar mais em cada território e suas particularidades, com ações que diversifiquem as formas de mobilização.

Efeito do treinamento pliométrico de curta duração no salto vertical e velocidade de sprint em jogadores de vôlei / Effect of short duration plyometric training on vertical jump and sprint speed in volleyball players

INTRODUÇÃO: O voleibol é um esporte de ritmo acelerado que envolve projeções verticais e horizontais da bola por parte do jogador. O uso de treinamento pliométrico é um método popular para melhorar o desempenho dos jogadores. OBJETIVO: O presente estudo visa verificar o efeito de quatro semanas de treinamento pliométrico em jogadores de voleibol. MÉTODO: Estudo randomizado, controlado, de grupos paralelos. Foram triados 39 participantes para participação no estudo, dos quais 30 foram selecionados seguindo os critérios de inclusão e exclusão da pesquisa. Os critérios de inclusão foram: jogadores de voleibol na faixa etária de 18 a 24 anos, de ambos os sexos, experiência de jogo de no mínimo um ano e disponibilidade para participar. Os critérios de exclusão compreendiam jogadores com histórico de lesão nos últimos seis meses, qualquer distúrbio neurológico ou musculoesquelético e qualquer condição psicológica. Os participantes selecionados foram alocados aleatoriamente no Grupo A e Grupo B usando o método de sorteio. O Grupo A recebeu treinamento pliométrico por três dias em uma semana, e o Grupo B foi solicitado a continuar seus exercícios regulares de rotina. A duração total da intervenção foi de quatro semanas. A medida de resultado para o estudo foi a velocidade do sprint e a altura do salto vertical. A velocidade de sprint foi medida pelo teste de sprint de 20 m e a altura do salto vertical foi medida pelo teste sargent jump. A avaliação foi feita no início e no final de quatro semanas. O teste t não pareado foi usado para analisar as diferenças entre os grupos e o teste t pareado foi usado para analisar as diferenças dentro do grupo nas variáveis de resultado. RESULTADOS: O resultado do estudo mostrou uma melhora significativa na altura do salto vertical (MD= -7,133, IC 95% (-12,657,- 1,609) e nenhuma melhora significativa na velocidade do sprint quando comparações entre grupos foram feitas (MD=0,084, 95% IC (-0,177,-,345) com um tamanho de efeito de 0,75 para a altura do salto vertical. A comparação dentro do grupo foi considerada significativa apenas para a altura do salto vertical no Grupo A, e não houve melhora significativa na velocidade de sprint para ambos Grupo A e B. CONCLUSÃO: Quatro semanas de programa pliométrico é eficaz em melhorar a altura do salto vertical e não a velocidade de sprint em jogadores de voleibol.

INTRODUCTION: Volleyball is a fast-paced sport that involves vertical and horizontal projections of the ball by the player. The use of plyometric training is a popular method to enhance performance in players. OBJECTIVE: The present study aims to see the effect of short-duration plyometric training on vertical jump and sprint speed in volleyball players. METHOD: This study is a parallel group randomized controlled trial. Thirtynine participants were screened for participation in the study, of which 30 were selected following the inclusion and exclusion criteria for the study. The inclusion criteria for the study comprised of volleyball players of age group 18 to 24 years, both males and females, with playing experience of at least one year, and willing to participate. The exclusion criteria for the study included players with a history of injury in the last six months, any reported neurological or musculoskeletal disorder, and any psychological condition. The selected participants were randomly allocated to Group A and Group B using the lottery method. Group A was given plyometric training for three days a week and Group B was asked to continue their regular routine exercises and playing schedule. The total duration of the intervention was four weeks. The outcome measure for the study was sprint speed and vertical jump height. Sprint speed was measured by the 20 m sprint test, and the vertical jump height was measured by the Sargent jump test. The assessment was done at the baseline and at the end of four weeks. An unpaired t-test was used to analyze between-group differences, and paired t-test was used to analyze the within-group differences in the outcome variables. The significance level was set as p<0.05. RESULTS: The result of the study showed a significant improvement in vertical jump height (MD= -7.133, 95% CI-12.657, -1.609) and no significant improvement in sprint speed when between-group comparisons were made (MD=0.084, 95%CI -0.177,-.345) with an effect size of 0.75 for vertical jump height. The within-group comparison was found significant only for vertical jump height in Group A, and there was no significant improvement was found in sprint speed for both Group A and B. FINAL CONSIDERATIONS: The short-duration plyometric training is effective in improving the vertical jump height and not the sprint speed in volleyball players. The specificity of plyometric training is important for optimal improvement in sports performance.

Evaluation of AIIMS Modified INCLEN Tool for Diagnosis of Epilepsy

Objectives: To evaluate the AIIMS Modified INCLEN tool for the diagnosis of epilepsy. Methods: This cross-sectional study enrolled 250 children aged 1 month to 18 years presenting with complaints of abnormal body movements to either the pediatric or neurology outpatient departments in our institution between October 1, 2018 and June 30, 2020. The All India Institute of Medical Sciences (AIIMS) modified International Clinical Epidemiology Network (INCLEN) diagnostic tool for epilepsy (AIIMS modified INDT-EPI) was administered and a diagnosis was made, which was further verified by a pediatrician or a neurologist. Specificity, sensitivity, positive predictive value (PPV) and negative predictive value (NPV) were calculated. Results: The study tool had a sensitivity of 87.6% and specificity of 84.0%. The PPV and NPV of the study tool were 86.8% and 84.9%, respectively. Conclusion: The study tool has good psychometric properties for physician assessment with regard to diagnosis of epilepsy.

Comparison of Weight for Height and BMI for Age for Estimating Overnutrition Burden in Under-Five Populations With High Stunting Prevalence

Background: Overnourished under-five children are anthropometrically classified as either being at possible risk of overweight, overweight or obese and defined so, when either weight for height or body mass index for age (BMI-for-age) are >1SD to 2SD, >2SD to 3SD and >3SD, respectively of the analogous World Health Organization standards. Aim: To compare weight for height and BMI for age definitions for quantifying overnutrition burden. Methods: Theoretical consequences of ignoring age were evaluated by comparing, at varying height for age z-scores, the age- and sex-specific cutoffs of BMI that would define overnutrition with these two metrics. Overnutrition prevalence was then compared in simulated populations (short, intermediate and tall) and real-life datasets from India. Results: In short (-2SD) children, the BMI cutoffs with weight for height criteria were lower in comparison to BMI for age till 7-8 months, but higher at later ages. In National Family Health Survey-4, India dataset (short population), overnutrition (>1SD) prevalence with weight for height was higher from 0-0.5 years (exclusive breastfeeding age), but lower at subsequent ages. The prevalence difference (weight for height - BMI for age) in 0.5-5 years was -2.26% (6.57% vs 8.83%); this attenuated in 0-5 years (-1.55%; 7.23% vs 8.78%). The discrepancy was maximal for stunted children and was lower in girls. A similar pattern, of lower magnitude, was observed for overweight (>2SD) comparison. In intermediate and tall populations, there were no meaningful differences. Conclusion: The two definitions produce cutoffs, and hence estimates of overnutrition, that differ with the age, sex, and height of under-five children. The relative invariance, with age and height, of BMI for age, favors its use.

Fracture of a Flow Diverter in the Cervical Internal Carotid Artery Due to Eagle Syndrome / 신경중재치료의학

In Eagle syndrome, elongated styloid processes may provoke internal carotid dissection and pseudoaneurysm causing stroke and data regarding possible complications or long-term results of pseudoaneurysm treatment using a flow diverter are limited. We report a case of a dissection-related pseudoaneurysm in the left cervical carotid artery treated by implantation of a flow diverter. Follow-up imaging of the flow diverter showed fracture of a continuous radiopaque marker at 3 months and fracture of a second continuous radiopaque marker at 7 months, while contrasting of the vessel was preserved. At the time of angiographic control (8 months after implantation), the flow diverter and the extracranial left internal carotid artery were occluded, and the patient did not experience any symptoms throughout the period.

Quantification of blood loss for the diagnosis of postpartum hemorrhage: a systematic review and meta-analysis / Cuantificación de la pérdida de sangre para el diagnóstico de hemorragia posparto: revisión sistemática y metanálisis / Quantificação da perda sanguínea para o diagnóstico de hemorragia pós-parto: revisão sistemática e metanálise

ABSTRACT Objective: to compare the effectiveness of different diagnostic methods to estimate postpartum blood volume loss. Methods: a systematic review of effectiveness according to PRISMA and JBI Protocol. Searches in PubMed/MEDLINE, LILACS, Scopus, Embase, Web of Science and CINAHL, with descriptor "Postpartum Hemorrhage" associated with keyword "Quantification of Blood Loss". Tabulated extracted data, presented in metasynthesis and meta-analysis was applied to quantitative data. To assess risk of bias, JBI Appraisal Tools were applied. Results: fourteen studies were included, published between 2006 and 2021. Quantification of loss by any method was superior to visual estimation and is highly recommended, however the studies' high heterogeneity did not allow estimating this association. Conclusion: the studies' high heterogeneity, with a probable margin of error given the uncontrolled factors, indicates the need for further studies, however quantification proved to be effective in relation to visual estimate.

RESUMEN Objetivo: comparar la efectividad de diferentes métodos diagnósticos para estimar la pérdida de volumen sanguíneo posparto. Métodos: revisión sistemática de efectividad según PRISMA y Protocolo JBI. Búsquedas en bases de datos: PubMed/MEDLINE, LILACS, Scopus, Embase, Web of Science y CINAHL, con el descriptor "Postpartum Hemorrhage" asociado a la palabra clave "Quantification of Blood Loss". Los datos extraídos tabulados fueron presentados en metasíntesis y metanálisis se aplicaron a los datos cuantitativos. Para evaluar el riesgo de sesgo, se aplicaron las herramientas de evaluación de JBI. Resultados: se incluyeron 14 estudios, publicados entre 2006 y 2021. La cuantificación de pérdida por cualquier método fue superior a la estimación visual y es muy recomendable, sin embargo, la alta heterogeneidad de los estudios no permitió estimar esta asociación. Conclusión: la alta heterogeneidad de los estudios, con probable margen de error dado el descontrol de los factores, indica la necesidad de más estudios, sin embargo la cuantificación demostró ser efectiva en relación a la estimación visual.
