ABSTRACT Objective: To describe the functional results, recurrence rate, postoperative radiographic appearance, and complications of patients undergoing the Latarjet procedure over 24 months. Methods: Retrospective case series, including adult patients with recurrent traumatic anterior glenohumeral dislocation undergoing the Latarjet procedure. We clinically evaluated patients preoperatively by the Rowe score and at six, 12, and 24 months after the procedure. The positioning, consolidation, and resorption of the graft were analyzed by plain radiography. The recurrence rates and other complications were also described. Results: We analyzed 40 patients (41 shoulders). The Rowe score median increased from 25 before surgery to 95 at 24 months after surgery (p < 0.001). We observed graft resorption in three cases (7.3%) and consolidation in 39 (95.1%). Most grafts presented adequate placement. We observed two recurrences (4.8%), one case of dislocation and one of subluxation. Seven patients (17.1%) had a positive apprehension test. The study had no cases of infection, neuropraxia, or graft breakage. Conclusion: Latarjet surgery is a safe and effective procedure in the treatment of recurrent anterior dislocation of the shoulder. This surgery enables a statistically significant improvement according to the Rowe score, with a low number of recurrences. Level of Evidence IV, Case Series.

Abstract Picoplankton are central global carbon (C) cycling players and often dominate the ocean plankton communities, especially in low latitudes. Therefore, evaluating picoplankton temporal dynamics is critical to understanding microbial stocks and C fluxes in tropical oceans. However, the lack of studies on low-latitude picoplankton communities translates into a common conception that there is an absence of seasonality. Herein, we studied the temporal variation in abundance (measured by flow cytometry), and carbon flux (taking bacterial production and respiration as proxies) of the picoplanktonic community for the first time, as well as their environmental drivers in a low-latitude (05° 59’ 20.7″S 035° 05’ 14.6″W) Atlantic coastal station. We performed monthly samplings between February 2013 and August 2016 in a novel microbial observatory – hereafter called the Equatorial Atlantic Microbial Observatory – established on the northeastern Brazilian Atlantic coast. Our results revealed stability in temporal dynamics of picoplankton, despite a considerable inter-annual variation, with some related to the El Niño (ENSO) event in 2015. However, weak environmental relationships found were not enough to explain the variation in picoplankton’s abundance, which suggests that other factors such as biological interactions may lead to picoplankton abundance variation over time. Heterotrophic bacteria dominated picoplankton during the entire study period and between photosynthetic counterparts, and Synechococcus showed greater relative importance than picoeukaryotes. These results bring a novel perspective that picoplankton may exhibit more pronounced fluctuations in the tropical region when considering inter-annual intervals, and is increasing prokaryotic contribution to carbon cycling towards the equator.

ABSTRACT Objective: To describe a protocol of obtention of mesenchymal stem cells and to report their use as a biological adjuvant in three patients undergoing arthroscopic rotator cuff repair. Methods: Case series of patients who underwent arthroscopic repair of isolated full-thickness supraspinatus tear using mesenchymal stem cells obtained from the bone marrow as a biological adjuvant. All patients were operated on at the same institution, by a surgeon with 13 years of experience. The cells were applied at the end of the procedure, at the tendon-bone interface, at an approximate concentration of 2,000,000 mesenchymal cells/mm3 and a total volume of 5 ml. Results: All patients improved with the procedure, with one excellent and two good results. All cases overcame the minimally important clinical difference. All cases reached tendon healing, without partial or complete re-tears. We observed no complications. Conclusion: Arthroscopic rotator cuff repair with added mesenchymal cells obtained from bone marrow and submitted to a cell expansion process led to good functional results and healing in all cases in the sample, with no complications. Level of Evidence IV, Case Series.

Abstract This document aims to predict the level of innovation in manufacturing companies in Colombia between the years 2017-2018. A forecasting mechanism for innovation performance has been constructed using Neural Networks (NNs). This model considers the objectives of innovation, the obstacles to innovation, the knowledge networks, and the technical information of each one of the firms. Results show that demand push, vertical sources, financial obstacles, and, qualified personnel are the most important variables in predicting innovative performance. Our empirical analysis uses firm-level innovation survey data from the EDIT (Encuesta de Desarrollo e Innovación Tecnológica in Spanish, Technological Development, and Innovation Survey in English) for Colombia for the years 2017-2018.

Resumo Objetivo O objetivo do presente estudo foi avaliar a eficácia e a segurança da reconstrução capsular superior (RCS) com a utilização do aloenxerto de fáscia lata. Métodos Uma série de casos prospectivos de 15 pacientes com ruptura irreparável do supraespinhal foi submetida a RCS com aloenxerto de fáscia lata, sendo adotada como desfecho primário a escala American Shoulder and Elbow Surgeons (ASES, na sigla em inglês) aos 12 meses do pós-operatório. Como desfechos secundários, foram adotadas as escalas da University of California Los Angeles (UCLA, na sigla em inglês), Constant-Murley, e Single Assessment Numeric Evaluation (SANE, na sigla em inglês), além da amplitude de movimento. Os parâmetros radiológicos também foram avaliados por radiografias simples e ressonância magnética (RM). Resultados Quinze pacientes completaram 12 meses de acompanhamento pós-operatório. O escore ASES aumentou de 34,0 para 73,0 (p= 0,005). As escalas UCLA, Constant-Murley e SANE também apresentaram diferenças estatisticamente significativas (p= 0,001; p= 0,005; e p= 0,046). Na avaliação da amplitude de movimento, houve melhora na elevação e rotação externa (95 a 140°, p= 0,003; 30 a 60°, p= 0,007). Seis pacientes (40%) tiveram cicatrização completa do enxerto. Os desfechos clínicos foram significativamente maiores nos pacientes que apresentaram cicatrização do enxerto. Conclusões A RCS com aloenxerto de fáscia lata é um procedimento seguro e eficaz com um curto acompanhamento de tempo. Nível de evidência IV; Estudo Terapêutico; Série de casos.

Abstract Objective The objective of the present study was to evaluate the efficacy and safety of superior capsular reconstruction (SCR) using fascia lata allograft. Methods A prospective case series of 15 patients with irreparable supraspinatus tear who underwent SCR using fascia lata allograft. The American Shoulder and Elbow Surgeons (ASES) scale at 12 months after surgery was the primary outcome. The University of California Los Angeles (UCLA), Constant-Murley, and Single Assessment Numeric Evaluation (SANE) scales, in addition to the range of motion, were secondary outcomes. Radiological parameters were also evaluated by simple radiographs and magnetic resonance imaging (MRI). Results Fifteen patients completed 12 months of postoperative follow-up. The ASES score increased from 34.0 to 73.0 (p= 0.005). The UCLA, Constant-Murley, and SANE scales also showed statistically significant differences (p= 0.001; p= 0.005; and p= 0.046). In the evaluation of range of motion, there was improvement in elevation and in external rotation (95 to 140°, p= 0.003; 30 to 60°, p= 0.007). Six patients (40%) had complete graft healing. The clinical outcomes were significantly higher in the patients who presented graft healing. Conclusions Superior capsular reconstruction using a fascia lata allograft is a safe and effective procedure in short follow-up. Level of Evidence IV; Therapeutic Study; Case Series.

Resumo Objetivo Avaliar a correlação do conceito de glenoid track e da perda óssea da cavidade glenoidal com a taxa de recidiva de luxação e pontuação na escala de Rowe. Métodos Estudo retrospectivo que aferiu o glenoid track e a perda óssea da cavidade glenoidal por ressonância magnética pré-operatória. Foram incluídos pacientes submetidos a reparo artroscópico primário de Bankart anterior. Não foram incluídos pacientes com perda óssea da cavidade glenoidal maior que 21%, rotura do manguito rotador, fratura de cintura escapular, instabilidade posterior ou multidirecional. A pontuação pela escala de Rowe foi o desfecho primário, e a taxa de recidiva foi o desfecho secundário. Resultados Cento e dois pacientes foram incluídos. A recidiva foi relatada por 8 pacientes (7,8%). Quatro pacientes (50%) do grupo com recidiva apresentaram lesão da cavidade glenoidal maior que 13,5% contra 24 (25,5%) do grupo sem recidiva (p= 0,210), com valor preditivo negativo de 94,6%. Três pacientes (37,5%) do grupo com recidiva foram considerados off-track, contra 13 (13,8%) do grupo sem recidiva (p= 0,109), com valor preditivo negativo de 94,2%. Pacientes com valor absoluto do glenoid track menor ou igual a 1,5 mm tiveram piores resultados em relação ao grupo com recidiva, sendo que 6 pacientes (75%) apresentaram recidiva (p= 0,003). Conclusão Lesão off-track e perda óssea da cavidade glenoidal maior que a subcrítica não apresentam relação significativa com a taxa de recidiva e a pontuação de Rowe, apesar do alto valor preditivo negativo. O corte do valor absoluto do glenoid track em 1,5 mm apresentou relação significativa com a taxa de recidiva.

Abstract Objective To evaluate the correlation of the glenoid track and glenoidal bone loss with the recurrence dislocation rate and the Rowe score. Methods Retrospective study that assessed the glenoid track and glenoidal bone loss through preoperative magnetic resonance imaging. Patients undergoing primary arthroscopic repair of anterior Bankart were included. Patients with glenoidal bone loss greater than 21%, rotator cuff tear, scapular waist fracture, and posterior or multidirectional instability were not included. Rowe score were the primary outcome, and the recurrence rate was the secondary outcome. Results One hundred and two patients were included. Postoperative recurrent instability was reported by 8 patients (7.8%). Four patients (50%) in the group with recurrence presented glenoidal bone loss greater than 13.5% against 24 (25.5%) in the group without recurrence (p= 0.210), with a negative predictive value of 94.6%. Three patients (37.5%) in the recurrence group were considered off-track, against 13 (13.8%) in the group without recurrence (p= 0.109), with a negative predictive value of 94.2%. Patients with absolute glenoid track value ≤ 1.5 mm had worse results in relation to the recurrence group, with 6 patients (75%) presenting recurrence (p= 0.003). Conclusion Off-track injury and glenoidal bone loss greater than the subcritical are not related to the recurrence rate and Rowe score, despite the high negative predictive value. The cut of the absolute value of the glenoid track at 1.5 mm had a significant relationship with the recurrence rate.

Resumo Objetivos Descrever o resultado funcional do tratamento não operatório de fraturas desviadas da extremidade proximal do úmero (FEPU) pela escala da American Shoulder and Elbow Surgeons (ASES, na sigla em inglês) após 12 meses e avaliar se as diferentes classificações e medidas radiográficas iniciais têm correlação com os resultados clínicos. Métodos Foram avaliados em tempos padronizados (3, 6 e 12 meses), 40 pacientes > 60 anos com FEPU submetidos ao tratamento não operatório. Foram utilizadas as escalas da ASES, Constant-Murley e Single Assessment Numeric Evaluation (SANE, na sigla em inglês). As variáveis radiográficas incluíram as classificações de Neer e Resch, a presença de fratura e desvio dos tubérculos, cominuição metafisária, lesão periosteal medial, desvios angulares e translacionais da cabeça no plano coronal e sagital e desvio dos tubérculos. Resultados Observamos resultados pela escala de ASES de 77,7 23,2 para toda a amostra, pelade Constant-Murley de 68,7 16e de 82,6% paraa escala em relação aolado contralateral.AescaladeSANEaos12mesesfoide84,8 19.Oscritériosradiográficosque apresentaram influência negativa no resultado clínico pela escala de ASES aos 12 meses foram a gravidade pela classificação de Neer e pelo desvio angular no plano coronal (mensurado pelo ângulo cabeça-diáfise) e a presença de fratura dos tubérculos. Conclusão O tratamento não operatório de fraturas desviadas da extremidade proximal do úmero em pacientes idosos resulta em bons resultados clínicos. Os resultados clínicos são influenciados negativamente pelo desvio angular da cabeça do úmero e pela presença de fratura dos tubérculos maior e menor, assim como pela classificação de Neer.

Abstract Objectives To describe the functional result of the conservative treatment of displaced proximal humerus fractures (PHF) using the American Shoulder and Elbow Surgeons (ASES) score after 12 months and assess whether the different initial classifications and radiographic measurements are related to clinical results. Methods Forty patients > 60 years old, with displaced PHUs submitted to conservative treatment were evaluated at standardized times (3, 6, and 12 months). The American Society of Shoulder and Elbow Surgeons (ASES), Constant-Murley and Single Assessment Numeric Evaluation (SANE) scales were used as clinical outcomes. Radiographic variables included the Neer and Resch classifications, the presence and displacement of tuberosity fracture, metaphyseal comminution, medial periosteal lesion, and angular and translational deviations of the head in the coronal and sagittal plane. Results The result of the ASES score was 77.7 23.2 for the whole sample, the mean absolute values of the Constant-Murley score were 68.7 16 and 82.6% for the scale relative to the contralateral side. The SANE scale at 12 months was 84.8 19. We observed that the severity of the Neer classification and the coronal plane angular deviation (measured by the head-shaft angle) and the presence of fractures in both tuberosities negatively influenced the ASES score after 12 months of treatment. Conclusion Nonoperative treatment of displaced proximal humerus fractures in elderly patients results in good clinical results. Clinical results are negatively influenced by the angular deviation of the humeral head and the presence of fractures of the greater and lesser tubercles, as well as by the Neer classification.

ABSTRACT BACKGROUND: Instability or tears of the long head of the biceps tendon (LHBT) may be present in more than 35% of rotator cuff repairs (RCR). OBJECTIVE: To compare clinical results from patients undergoing arthroscopic RCR, according to the procedure performed at the LHBT. DESIGN AND SETTING: Retrospective cohort study designed at the shoulder and elbow clinic of Instituto de Ortopedia e Traumatologia, Hospital das Clinicas, Faculdade de Medicina, Universidade de Sao Paulo, Brazil. METHODS: Functional results among patients were compared using the American Shoulder and Elbow Surgeons (ASES) and University of California Los Angeles (UCLA) scales, according to the LHBT approach adopted: no procedure, tenotomy or tenodesis. RESULTS: We evaluated 306 shoulders (289 patients): 133 underwent no procedure at the LHBT, 77 tenotomy and 96 tenodesis. The ASES scale at 24 months showed no difference (P = 0.566) between the groups without LHBT procedure (median 90.0; interquartile range, IQR 29), tenotomy (median 90.0; IQR 32.1) or tenodesis (median 94.4; IQR 22.7); nor did the UCLA scale (median 33; IQR 7 versus median 31; IQR 8 versus median 33; IQR 5, respectively, P = 0.054). The groups differed in the preoperative functional assessment according to the ASES and UCLA scale, such that the tenodesis group started from higher values. However, there was no difference in pre and postoperative scores between the groups. CONCLUSION: Tenodesis or tenotomy of the LHBT, in the sample analyzed, did not influence the clinical results from RCR, as assessed using the ASES and UCLA scales.

ABSTRACT Background: Intracerebral hemorrhage (ICH) is associated with an ominous outcome influenced by the time to hospital presentation. Objective: This study aims to identify the factors that influence an early hospital arrival after ICH and the relationship with outcome. Methods: In this multicenter registry, patients with confirmed ICH on CT scan and well-known time of symptoms onset were studied. Clinical data, arrival conditions, and prognostic scores were analyzed. Multivariate models were built to find independent predictors of < 6 h arrival (logistic regression) and in-hospital death (Cox proportional-hazards model). Results: Among the 473 patients analyzed (51% women, median age 63 years), the median delay since onset to admission was 6.25 h (interquartile range: 2.5-24 h); 7.8% arrived in < 1 h, 26.3% in < 3 h, 45.3% in < 6 h, and 62.3% in < 12 h. The in-hospital, 30-day and 90-day case fatality rates were 28.8%, 30.0%, and 32.6%, respectively. Predictors of arrival in < 6 h were hypertension treatment (odds ratios [OR]: 1.675, 95% confidence intervals [CI]: 1.030-2.724), ≥ 3 years of schooling (OR: 1.804, 95% CI: 1.055-3.084), and seizures at ICH onset (OR: 2.416, 95% CI: 1.068-5.465). Predictors of death (56.9% neurological) were systolic blood pressure > 180 mmHg (hazards ratios [HR]: 1.839, 95% CI: 1.031-3.281), ICH score ≥ 3 (HR: 2.302, 95% CI: 1.300-4.074), and admission Glasgow Coma Scale < 8 (HR: 4.497, 95% CI: 2.466-8.199). Early arrival was not associated with outcome at discharge, 30 or 90 days. Conclusions: In this study, less than half of patients with ICH arrived to the hospital in < 6 h. However, early arrival was not associated with the short-term outcome in this data set.

Abstract Objective To evaluate the functional outcome of patients who underwent partial arthroscopic repair of massive rotator cuff tears. Methods Retrospective case series evaluating patients with massive rotator cuff tears who underwent partial arthroscopic repair. The primary outcome was the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) at 24 months. The secondary outcomes were the Modified-University of California at Los Angeles Shoulder Rating Scale (UCLA), and the following subdomains: satisfaction, active forward flexion and strength of forward flexion subdomains. Results We evaluated 33 patients. The ASES scale evolved from 39.7 ± 19.6 to 77.6 ± 17.4 (p< 0.001). The UCLA scale evolved from 13.3 ± 5.5 to 27.9 ± 5.6 (p< 0.001). The satisfaction rate was 97%. The number of patients with active forward flexion > 150° increased from 12 (36.4%) to 25 (75.8%) (p= 0.002). The number of patients with normal or good strength of forward flexion increased from 9 (27.3%) to 22 (66.7%) (p = 0.015). Conclusion Partial repair of irreparable rotator cuff tears leads to significant improvement according to the ASES and UCLA scales.

RESUMO Introdução Avaliar a relação entre o polimorfismo genético das metaloproteinases 1 e 13 da matriz e a rigidez pós-traumática do cotovelo, assim como a associação de outros fatores de risco com essa condição. Material e método Foram avaliados 20 pacientes com rigidez pós-traumática do cotovelo e 12 controles com distúrbios traumáticos do cotovelo sem contratura. O ácido desoxirribonucleico (DNA) de voluntários foi obtido a partir de células epiteliais da mucosa bucal. Os genótipos MMP-1 e MMP-13 foram determinados usando ensaios de polimorfismo de comprimento de fragmento de restrição de PCR. Resultados Não encontramos diferença significativa na frequência de genótipos e alelos entre os grupos teste e controle para o polimorfismo das metaloproteinases 1 e 13. Observamos que os genótipos 1G/2G e 2G/2G de MMP-1 estavam presentes em 65% (13/20) dos pacientes com rigidez articular e 50% (6/12) dos controles (p = 0,599). Os genótipos A/A e A/G da MMP-13 foram obtidos em 95% (19/20) dos pacientes e 91,6% (11/12) dos controles (p = 0,491). Dentre os fatores prognósticos para rigidez de cotovelo, apenas o tempo de imobilização se correlacionou positivamente. O tempo médio de imobilização para casos e controles foi de 16 ± 10 dias e 7 ± 7 dias, respectivamente (p = 0,017). Conclusões O polimorfismo genético de MMP-1 na posição -1607 e MMP-13 na posição -77 não foi associado à rigidez pós-traumática do cotovelo.

ABSTRACT Introduction To evaluate the relationship between the genetic polymorphism of matrix metalloproteinases 1 and 13 and posttraumatic elbow stiffness, as well as the association of other risk factors with this condition. Materials and methods We evaluated 20 patients with posttraumatic elbow stiffness and 12 controls with traumatic elbow disorders without contracture. Deoxyribonucleic acid (DNA) was obtained from buccal mucosa epithelial cells of the volunteers. The MMP-1 and MMP-13 genotypes were determined using PCR-restriction fragment length polymorphism assays. Results We did not find any significant differences in the frequency of genotypes and alleles between the test and control groups for the polymorphism of metalloproteinases 1 and 13. We observed that genotypes 1G/2G and 2G/2G of MMP-1 were present in 65% (13/20) of patients with articular stiffness and 50% (6/12) of controls (p = 0.599). Genotypes A/A and A/G of MMP-13 were obtained in 95% (19/20) of patients and 91.6% (11/12) of controls (p = 0.491). Among the prognostic factors for elbow stiffness, only immobilization time correlated positively. The mean immobilization time for cases and controls were 16 ± 10 days and 7 ± 7 days, respectively (p = 0.017). Conclusion The genetic polymorphism of MMP-1 at position -1607 and MMP-13 at position -77 was not associated with post-traumatic elbow stiffness.

Challenges in the process of inclusion of students with disabilities are still experienced today. In this sense, the identification of problems and potential interventions to improve teaching and access to education are fundamental. The present work aimed to explain the challenges of inclusive education in Brazilian educational institutions and to investigate which didactic and pedagogical attitudes are being implemented in the country. An integrative literature review with descriptive analysis and qualitative approach of articles published between the years 2000 and 2020 was carried out. Articles indexed in the Scientific Electronic Library On-Line-SCIELO, Portal de periódicos da CAPES and Literatura Latino-Americana e do Caribe em Ciências da Saúde-LILACS databases were included. Overall, 18 articles met all the inclusion criteria and served as the basis for extracting the information for analysis. As a result, it was found that teachers and educational institutions lacked the capacity to deal with students with special educational needs. Among the problems and difficulties most reported was the lack of preparation of teachers, lack of specific teaching methodologies and lack of adequate physical structures in schools. As strategies for improving the inclusion process, the use of games was highlighted. It is hoped that this study will serve as a mechanism for reflection and awareness for all agents involved in the inclusion of students with disabilities and that it will contribute to the adequacy and improvement of public policies for the qualification of teachers, as well as the adequacy of educational institutions in Brazil.

Los retos en el proceso de inclusión de los estudiantes con discapacidades se siguen experimentando hoy en día. En este sentido, la identificación de los problemas y las posibles intervenciones para mejorar la enseñanza y el acceso a la educación son fundamentales. El presente trabajo tuvo como objetivo explicar los desafíos de la educación inclusiva en las instituciones educativas de Brasil e investigar qué actitudes didácticas y pedagógicas se están implementando en el país. Se realizó una revisión bibliográfica integradora con análisis descriptivo y enfoque cualitativo de los artículos publicados entre 2000 y 2020. Se incluyeron artículos indexados en las bases de datos Scientific Electronic Library On-Line-SCIELO, Portal de periódicos da CAPES y Literatura Latino-Americana e do Caribe em Ciências da Saúde-LILACS. En general, 18 artículos cumplieron todos los criterios de inclusión y sirvieron de base para la extracción de información para el análisis. Como resultado, se comprobó que los profesores y los centros educativos carecían de formación para tratar a los alumnos con necesidades educativas especiales. Entre los problemas y dificultades más señalados está la falta de preparación de los profesores, la falta de metodologías de enseñanza específicas y la falta de estructuras físicas adecuadas en las escuelas. Como estrategias para mejorar el proceso de inclusión, se destacó el uso de juegos. Se espera que este estudio sirva como mecanismo de reflexión y sencsibilización para todos los agentes implicados en la inclusión de alumnos con discapacidad y que contribuya a la adecuación y mejora de las políticas públicas de cualificación del profesorado, así como a la adecuación de las instituciones educativas en Brasil.

Desafios no processo de inclusão de alunos com deficiência ainda são vivenciados atualmente. Nesse sentido, a identificação de problemas e potenciais intervenções para a melhoria do ensino e acesso à educação são fundamentais. O presente trabalho teve como objetivo explanar sobre os desafios da educação inclusiva em instituições de ensino do Brasil e investigar quais atitudes didático pedagógicas estão sendo implantadas no país. Foi realizada uma revisão integrativa de literatura com análise descritiva e abordagem qualitativa de artigos publicados no período entre os anos 2000 e 2020. Foram incluídos artigos indexados nas bases de dados Scientific Eletronic Library On-Line–SCIELO, Portal de periódicos da CAPES e Literatura Latino-Americana e do Caribe em Ciências da Saúde–LILACS. No geral, 18 artigos obedeceram a todos os critérios de inclusão e serviram de base para a extração das informações para análise. Como resultado constatou-se que professores e instituições de ensino apresentam falta de capacitação para lidar com alunos com deficiência. Dentre os problemas e dificuldades mais relatados destacou-se o despreparo dos professores, falta de metodologias pedagógicas específicas e carência em estrutura física adequadas nas escolas. Como estratégias para a melhoria do processo de inclusão, destacou-se o uso de jogos. Espera-se que este estudo sirva como mecanismo de reflexão e sensibilização para todos os agentes envolvidos na inclusão de alunos com deficiência e que contribua na adequação e aprimoramento de políticas públicas em prol da qualificação de professores, bem como na adequação das instituições de ensino no Brasil.

ABSTRACT Objective: To evaluate the association between HbA1c levels measured in the third trimester and the risk for large for gestational age (LGA) in neonates of mothers affected by gestational diabetes mellitus (GDM). Secondarily, we aimed to identify an ideal cut-off for increased risk of LGA amongst pregnant women with GDM. Materials and methods: Observational retrospective review of singleton pregnant women with GDM evaluated in a diabetes and pregnancy clinic of a tertiary and academic hospital. From January/2011 to December/2017, 1,085 pregnant women underwent evaluation due to GDM, of which 665 had an HbA1c test in the third trimester. A logistic regression model was performed to evaluate predictors of LGA. A receiver-operating-characteristic (ROC) curve was used to evaluate the predictive ability of third trimester HbA1c for LGA identification. Results: A total of 1,085 singleton pregnant women were evaluated during the study period, with a mean age of 32.9 ± 5.3 years. In the multivariate analysis, OGTT at 0 minutes (OR: 1.040; CI 95% 1.006-1.076, p = 0.022) and third trimester HbA1c (OR: 4.680; CI 95% 1.210-18.107, p = 0.025) were associated with LGA newborns. Using a ROC curve to evaluate the predictive ability of third trimester HbA1c for LGA identification, the optimal HbA1c cut-off point was 5.4% where the sensitivity was 77.4% and the specificity was 71.7% (AUC 0.782; p < 0.001). Conclusions: Few studies in the Mediterranean population have evaluated the role of HbA1c in predicting neonatal complications in women with GDM. A third trimester HbA1c > 5.4% was found to have good sensitivity and specificity for identifying the risk of LGA.

ABSTRACT Background: The recognition of stroke symptoms by patients or bystanders directly affects the outcomes of patients with acute cerebrovascular disease. Objective: The objective of the study was to assess the predictive value of the medical history and clinical features recognized by the patients’ bystanders to classify neurovascular syndromes in pre-hospital settings. Methods: We included 150 stroke patients of two Mexican referral centers: 50 with acute ischemic stroke (AIS), 50 with intracerebral hemorrhage (ICH), and 50 with subarachnoid hemorrhage (SAH). The performance of clinical prediction rules (CPR) to identify the stroke types was evaluated with features recognized by the patients’ bystanders before hospital arrival. The impact of CPRs on early arrival and in-hospital mortality was also analyzed. Results: Overall, 72% of the patients had previous medical evaluations in other centers before final referral to our hospitals, and therefore, only 45% had a final onset-to-door time <6 h, even when the first medical assessment had occurred in ≤1 h in 75% of cases. Clinical features noticed by the patients’ bystanders had low positive predictive values (PPV) for any stroke type. The CPR “language or speech disorder + focal motor deficit” had 93% sensitivity and a negative predictive value (NPV) of 84% to distinguish AIS. In SAH, headache alone showed a sensitivity of 84% and NPV of 97%. No CPR had an adequate performance on ICH. CPRs were not associated with final onset-to-door time. Altered consciousness, age ≥65 years, indirect arrival with stops before final referral, and atrial fibrillation increased in-hospital mortality. Conclusion: Clinical features referred by the witness of a neurovascular emergency have limited PPV, but adequate NPV in ruling-out AIS and SAH among stroke types. The use of CPRs had no impact on onset-to-door time or in-hospital mortality when the final arrival to a third-level center occurs with previous medical referrals.
