Cone-Beam Computed Tomography to evaluate changes in trabecular lower jawbone microstructure caused by bone loss and antiresorptive treatment / CBCT para evaluar cambios en la microarquitectura ósea de la mandíbula por pérdida ósea y tratamiento antirresortivo

ABSTRACT For decades, conventional histomorphometry has been the gold standard for analyzing trabecular bone microarchitecture. In recent years, micro-computed tomography (μCT) devices have been validated and are now considered the gold standard for quantifying bone microstructure Aim The aim of this preliminary report is to evaluate the usefulness of CBCT to assess trabecular mandible microstructural properties in normal ewes and to compare the quantitative changes associated with ovariectomy and antiresorptive treatment Material and Method Twelve adult Corriedale ewes (n=4/group) aged 3-4 years were divided into 3 groups and studied for 28 months. Eight ewes were ovariectomized (OVX) and divided into OVX and OVX+ZOL groups (n=4/group) which were treated as follows, by jugular injection: OVX received saline solution and OVX+ZOL received zoledronate (Zol) (Gador SA, CABA, Argentina) (4 mg/month). Another four ewes were subjected to sham surgery (SHAM group) and received saline solution Results Densitometry showed that jaw mineral content (BMC) and density (BMD) were significantly lower in OVX than in SHAM and OVX+ZOL ewes; no difference was observed between OVX+ ZOL and SHAM groups. CBCT analysis showed that bone volume (BV/TV%); trabecular thickness (TbTh); connectivity density (CD) and anisotropy degree (AD) were significantly lower, and trabecular spacing (TbSp), significantly higher in OVX than in SHAM ewes. AD was significantly higher and TbSp significantly lower in OVX+ZOL than in OVX groups. BV/TV%, TbTh and CD showed a clear tendency to being higher in OVX+ZOL than in OVX groups. No statistical difference was observed between OVX+ZOL and SHAM ewes. CBCT in a nondestructive, fast, very precise procedure for measuring bone morphometric indices without biopsies, which are not indicated for morphometric evaluation in osteoporosis Conclusions The current study demonstrated the potential of the high-resolution CBCT imaging to assess in vivo quantitative bone morphometry and bone quality of lower jaw cancellous bone under normal conditions and to differentiate changes associated with excessive bone loss induced by estrogen withdrawal and antiresorptive intervention.

RESUMEN Objetivo El presente informe preliminar evaluó la utilidad de Tomografía Computada de Haz Cónico (CBCT) para analizar las propiedades microestructurales trabeculares del maxilar inferior de ovejas y comparar los cambios cuantitativos asociados con la ovariectomía y tratamiento antirresortivo. Se estudiaron dieciséis ovejas Corriedale adultas de 3-4 años Materiales y Método Doce ovejas fueron ovariectomizadas (OVX) y divididas en 2 grupos: OVX y OVX+ZOL (n=4/grupo) cuyo tratamiento por inyección endovenosa en la yugular durante 28 meses fue el siguiente: OVX con solución salina y OVX+ZOL con zoledronato (Gador S.A. CABA. Argentina) (Zol) (4 mg/mes); 4 ovejas fueron sometidas a cirugía simulada (grupo SHAM) Resultados La densitometría (Lunar DPX) mostró que el contenido mineral del hueso maxilar (CMO) y la densidad (DMO) fueron significativamente más bajos en OVX que en SHAM y OVX+ZOL; no se observaron diferencias entre los grupos OVX+ZOL y SHAM. El análisis de las imágenes por CBCT (Planmeca Promax 3D Classic) mostró que el volumen óseo (BV/TV%); el espesor trabecular (TbTh); la densidad de conectividad (CD) y el grado de anisotropía (AD) fueron significativamente menores (p<0.05), y el espaciado trabecular (TbSp), significativamente mayor en OVX que en SHAM (p<0.05). AD fue significativamente mayor (p<0.05) y TbSp, significativamente menor en OVX+ZOL que en OVX (p<0.05). BV/TV%, TbTh y CD mostró una clara tendencia a ser mayor en OVX+ZOL que en OVX. No se observaron diferencias estadísticas entre OVX+ZOL y SHAM Conclusiones En base a nuestros resultados consideramos que CBCT presenta suficiente confiabilidad y validez para evaluar in vivo la morfometría cuantitativa y la calidad del hueso esponjoso del maxilar inferior en condiciones normales, así como para diferenciar los cambios en dichos parámetros asociados a la pérdida ósea excesiva por la caída estrogénica e intervención antirresortiva. Aunque se necesitan estudios futuros, nuestros resultados agregarían una herramienta no invasiva adicional para diferenciar la microestructura del hueso trabecular mandibular en estudios preclínicos , sentando las bases para su futura aplicación en la práctica clínica.

Dependence of radioactive iodine-131 capture by the lacrimal ducts on the tear production level

Purpose: Secondary acquired lacrimal duct obstruction (SALDO) is one of the complications of radioiodine therapy. SALDO is formed a few months after therapy if there is a sufficient uptake of radioactive iodine by the nasolacrimal duct. To date, risk factors leading to SALDO are unclear. The objective was to determine the correlation between the tear production level and radioactive iodine?131 uptake in the lacrimal ducts.Methods: Basal and reflex tear production was studied in 64 eyes prior to the therapy with radioactive iodine?131 after drug?induced hypothyroidism. The condition of the ocular surface was assessed using the Ocular Surface Disease Index (OSDI) questionnaire. Seventy?two hours after the radioactive iodine therapy, scintigraphy was performed, which determined the presence or absence of iodine?131 in the lacrimal ducts. T?statistics and the Mann–Whitney criterion were used to identify the differences between the groups. The differences were considered significant at P ? 0.05. The current tear production level in patients receiving radioiodine therapy was determined using a mathematical model. Results: A statistically significant difference between the basal (p = 0.044) and reflex (p = 0.015) tear production levels was found in cases with and without iodine?131 uptake by the lacrimal ducts. The probable current tear production level corresponds to the sum of basal and 10–20% of reflex tear production. The uptake of iodine?131 was found regardless of the OSDI results.Conclusion: The probability of iodine?131 uptake by the lacrimal ducts rises as the tear production level increases.

"Congelei com medo de me contaminar": tratando um caso de TEPT crônico com imobilidade tônica em uma fisioterapeuta da linha de frente na pandemia de COVID-19 / "I froze for fear of contaminating myself": treating a case of chronic PTSD with tonic immobility in a physiotherapist frontline during COVID-19 pandemic

RESUMO Objetivo: Neste estudo relatamos o caso de uma profissional de saúde com vivência de imobilidade tônica (IT) e posterior desenvolvimento de transtorno de estresse pós-traumático (TEPT) crônico em decorrência de trauma laboral por conta da COVID-19 que recebeu tratamento remoto com terapia cognitivo-comportamental focada no trauma (TCC-FT). Métodos: Relato de caso de uma paciente acompanhada por seis meses após o recebimento de TCC-FT remota. Resultados: Paciente do sexo feminino, de 36 anos, fisioterapeuta, que desenvolveu TEPT crônico e experienciou IT por medo da contaminação por coronavírus. As escalas psicométricas demonstraram que a TCC-FT reduziu consideravelmente os sintomas de TEPT e depressão e aumentou o apoio social e a resiliência. De acordo com o relato, o tratamento melhorou a concentração e a motivação, e reduziu o sentimento de culpa, a irritabilidade, a insegurança e o desconforto em lidar com outras pessoas. Conclusão: Este artigo demonstra que traumas decorrentes da COVID-19 podem ser capazes de desencadear IT e exemplifica um favorável desempenho da TCC-FT na melhoria global da saúde mental dos pacientes com TEPT crônico com vivência de IT.

ABSTRACT Objective: In this study, we report the case of a health professional with experience of tonic immobility (TI) and subsequent development of post-traumatic stress disorder (PTSD) as a result of occupational trauma due to COVID-19 who received remote treatment with Trauma-Focused Cognitive Behavioral Therapy (TF-CBT). Methods: A case report of a patient followed for six months after receiving remote TF-CBT. Results: A 36-year-old female patient, the physiotherapist who developed chronic PTSD and experienced TI for fear of coronavirus contamination. Psychometric scales demonstrated that TF-CBT considerably reduced PTSD and depression symptoms and increased social support and resilience. According to the report, the treatment improved concentration and motivation, and reduced feelings of guilt, irritability, insecurity, and discomfort in dealing with other people. Conclusion: This article demonstrates that trauma resulting from COVID-19 can trigger TI and exemplifies a favorable performance of TF-CBT in the global improvement of the mental health of patients with chronic PTSD who experience TI.

Papel Incremental da Classificação da New York Heart Association e dos Índices do Teste de Exercício Cardiopulmonar para Prognóstico na Insuficiência Cardíaca: um Estudo de Coorte / Incremental Role of New York Heart Association Class and Cardiopulmonary Exercise Test Indices for Prognostication in Heart Failure: A Cohort Study

Resumo Fundamento A precisão da classificação da New York Heart Association (NYHA) para avaliar o prognóstico pode ser limitada em comparação com os parâmetros objetivos do teste de exercício cardiopulmonar (TECP) na insuficiência cardíaca (IC). Objetivo Investigar o valor prognóstico da classificação da NYHA e da classe Weber. Métodos Foram incluídos pacientes ambulatoriais adultos com IC submetidos a TECP em um centro terciário brasileiro. A classe NYHA atribuída pelo médico e a classe Weber derivada do TECP foram estratificadas como "favorável" (NYHA I ou II com Weber A ou B) ou "adversa" (NYHA III ou IV com Weber C ou D). Pacientes com uma classe favorável e uma classe adversa foram definidos como "discordantes". O desfecho primário foi o tempo para mortalidade por todas as causas. Um valor de p bilateral < 0,05 foi considerado estatisticamente significativo. Resultados Foram incluídos 834 pacientes. A mediana de idade foi de 57 anos; 42% (351) eram do sexo feminino e a mediana da fração de ejeção do ventrículo esquerdo foi de 32%. Entre os pacientes com classes NYHA e Weber concordantes, aqueles com classes NYHA e Weber adversas tiveram mortalidade por todas as causas significativamente maior em comparação com aqueles com classes favoráveis ( hazard ratio [HR]: 5,65; intervalo de confiança de 95%: 3,38 a 9,42). Entre os pacientes com classes discordantes, não houve diferença significativa na mortalidade por todas as causas (HR: 1,38; intervalo de confiança de 95%: 0,82 a 2,34). No modelo multivariado, incrementos na classe NYHA (HR: 1,55 por aumento na classe; intervalo de confiança de 95%: 1,26 a 1,92) e reduções no VO 2 pico (HR: 1,47 por diminuição de 3 ml/kg/min; intervalo de confiança de 95%: 1,28 a 1,70) previu significativamente a mortalidade. Conclusões A classe NYHA atribuída pelo médico e as medidas objetivas do TECP fornecem informações prognósticas complementares para pacientes com IC.

Abstract Background The accuracy of the New York Heart Association (NYHA) classification to assess prognosis may be limited compared with objective cardiopulmonary exercise test (CPET) parameters in heart failure (HF). Objective To investigate the prognostic value of the NYHA classification in addition to Weber class. Methods Adult outpatients with HF undergoing CPET in a Brazilian tertiary care center were included. The physician-assigned NYHA class and the CPET-derived Weber class were stratified into "favorable" (NYHA I or II; Weber A or B) or "adverse" (NYHA III or IV; Weber C or D). Patients with one favorable class and one adverse class were defined as "discordant." The primary endpoint was time to all-cause mortality. A 2-sided p value < 0.05 was considered statistically significant. Results A total of 834 patients were included. Median age was 57 years; 42% (351) were female, and median left ventricular ejection fraction was 32%. Among patients with concordant NYHA and Weber classes, those with adverse NYHA and Weber classes had significantly higher all-cause mortality compared to those with favorable classes (hazard ratio [HR]: 5.65; 95% confidence interval [CI]: 3.38 to 9.42). Among patients with discordant classes, there was no significant difference in all-cause mortality (HR: 1.38; 95% CI: 0.82 to 2.34). In the multivariable model, increments in NYHA class (HR: 1.55 per class increase; 95% CI: 1.26 to 1.92) and reductions in peak VO 2 (HR: 1.47 per 3 ml/kg/min decrease; 95% CI: 1.28 to 1.70) significantly predicted mortality. Conclusions Physician-assigned NYHA class and objective CPET measures provide complementary prognostic information for patients with HF.

Is Mallampati classification a good screening test? A prospective cohort evaluating the predictive values of Mallampati test at different thresholds

Abstract Background There is currently some discussion over the actual usefulness of performing preoperative upper airway assessment to predict difficult airways. In this field, modified Mallampati test (MMT) is a widespread tool used for prediction of difficult airways showing only a feeble predictive performance as a diagnostic test. We therefore aimed at evaluating if MMT test would perform better when used as a screening test rather than diagnostic. Methods An accuracy prospective study was conducted with 570 patients undergoing general anesthesia for surgical procedures. We collected preoperatively data on sex, age, weight, height, body mass index (BMI), ASA physical status, and MMT. The main outcome was difficult laryngoscopy defined as Cormack and Lahane classes 3 or 4. Bivariate analyses were performed to build three different predictive models with their ROC curves. Results Difficult laryngoscopy was reported in 36 patients (6.32%). Sex, ASA physical status, and MMT were associated with difficult laryngoscopy, while body mass index (BMI) was not. The MMT cut-off with the highest odds ratio was the class II, which also presented significantly higher sensitivity (94.44%). The balanced accuracy was 67.11% (95% CI: 62.78-71.44%) for the cut-off of class II and 71.68% (95% CI: 63.83-79.54) for the class III. Conclusion MMT seems to be more clinically useful when the class II is employed as the threshold for possible difficult laryngoscopies. At this cut-off, MMT shows the considerable highest sensitivity plus the highest odds ratio, prioritizing thus the anticipation of difficult laryngoscopies.

Changes in the rest-activity rhythm in migraine patients are associated with anxiety symptoms

Objective: To characterize rest-activity rhythm in chronic migraine (CM) and to investigate the relationship between this rhythm and depressive and anxiety symptoms in patients with CM. Methods: This was a study of adults aged 20 to 40 years. The rest-activity rhythm of patients with CM (n=23) and non-headache controls (NH, n=23) was assessed by actigraphy for 15 days, and they completed the following assessments: Visual Analogue Scale for pain intensity; Headache Diary; Headache Impact Test-6; Morningness-Eveningness Questionnaire; Pittsburgh Sleep Quality Index; Epworth Sleepiness Scale; Beck Depression Inventory; and State-Trait Anxiety Inventory. Results: Patients with CM showed less activity over 24 hours and more fragmented sleep. Reduced interdaily stability of the rest-activity rhythm was observed, with less robustness of this rhythm in the CM group. Multiple linear regressions revealed a significant association between the rest-activity rhythm and trait anxiety variables in patients with CM, specifically regarding the relative amplitude of the cycle, activity throughout 24 hours and during sleep, and robustness of the rest-activity rhythm. Conclusions: Our findings provide evidence that the robustness of the rest-activity rhythm, activity throughout 24 hours, and sleep fragmentation are associated with trait anxiety in patients with CM. Clinical trial registration: Brazilian Clinical Trials Registry (registration number: RBR-4M5J4S).

Mutação missense de novo patogênica c. 2415C G (p. Asp805Glu) no gene ATP1A3 em paciente com hemiplegia alternante da infância com resposta favorável ao cloridrato de biperideno / A de novo missense pathogenic mutation c.2415C> G (p.Asp805Glu) in ATP1A3 gene in a patient with alternating hemiplegia of childhood with favorable response to biperiden hydrochloride

A Hemiplegia Alternante da Infância é um distúrbio neurológico grave e uma doença rara (1 em cada 100.000 recém-nascidos), caracterizado por ataques repetidos transitórios de hemiplegia episódica ou tetraplegia que podem durar minutos a horas, acompanhados por outros sintomas paroxísticos como anormalidades oculomotoras e autonômicas, distúrbios do movimento como ataxia, comprometimento cognitivo progressivo, convulsões, distonia e coreia. Os tratamentos atuais são amplamente sintomáticos. Neste relato de caso, apresentamos paciente do sexo feminino, 18 anos, na qual aos 10 meses apresentou o primeiro episódio aparente de crise convulsiva com versão ocular. O eletroencefalograma e tomografia computadorizada não revelaram anormalidades e foram administradas diversas medicações como fenobarbital, carbamazepina, valproato de sódio, topiramato, dicloridrato de flunarizina, clonazepam, cipro-heptadina e pizotifeno, todos sem resultado. Devidos aos sintomas extrapiramidais, paciente passou a utilizar biperideno, apresentando não só melhora da distonia, mas também no número de crises hemiplégicas. Aos 13 anos, ela foi diagnosticada com Hemiplegia Alternante da Infância na mutação patogênica missense de novo c.2415C G (p.Asp805Glu) no gene ATP1A3 apresentando boa resposta ao tratamento com cloridrato de biperideno.

Alternating hemiplegia of childhood is a severe neurological disorder and a rare disease (1 in 100,000 newborns), characterized by repeated transient attacks of episodic hemiplegia or tetraplegia that can last minutes to hours, accompanied by other paroxysmal symptoms such as oculomotor and autonomic abnormalities, movement disorders such as ataxia, progressive cognitive impairment, seizures, dystonia, and chorea. Current treatments are largely symptomatic. In this case report, we present a female patient, 18 years old, who presented the first apparent episode of seizure with ocular version at ten months of age. The electroencephalogram and CT scan revealed no abnormalities, and several medications such as phenobarbital, carbamazepine, sodium valproate, topiramate, flunarizine dihydrochloride, clonazepam, cyproheptadine and pizotifen were administered, all without result. Due to the extrapyramidal symptoms, the patient started using biperidene, showing improvement in dystonia and the number of hemiplegic seizures. At age 13, she was diagnosed with Alternating hemiplegia of Childhood in the pathogenic missense de novo mutation c.2415C>G (p.Asp805Glu) in the ATP1A3 gene showing a good response to treatment with biperidene hydrochloride.

Development of a hyperimmune equine serum therapy for COVID-19 in Argentina

The disease named COVID-19, caused by the SARS-CoV-2 coronavirus, is currently generating a global pandemic. Vaccine development is no doubt the best long-term immunological approach, but in the current epidemiologic and health emergency there is a need for rapid and effective solutions. Convalescent plasma is the only antibody-based therapy available for COVID-19 patients to date. Equine polyclonal antibodies (EpAbs) put forward a sound alternative. The new generation of processed and purified EpAbs containing highly purified F(ab’)2 fragments demonstrated to be safe and well tolerated. EpAbs are easy to manufacture allowing a fast development and scaling up for a treatment. Based on these ideas, we present a new therapeutic product obtained after immunization of horses with the receptor-binding domain of the viral Spike glycoprotein. Our product shows around 50 times more potency in in vitro seroneutralization assays than the average of convalescent plasma. This result may allow us to test the safety and efficacy of this product in a phase 2/3 clinical trial to be conducted in July 2020 in the metropolitan area of Buenos Aires, Argentina.

La enfermedad denominada COVID-19 es causada por el coronavirus SARS-CoV-2 y es actualmente considerada una pandemia a nivel global. El desarrollo de vacunas es sin duda la mejor estrategia a largo plazo, pero debido a la emergencia sanitaria, existe una necesidad urgente de encontrar soluciones rápidas y efectivas para el tratamiento de la enfermedad. Hasta la fecha, el uso de plasma de convalecientes es la única inmunoterapia disponible para pacientes hospitalizados con COVID-19. El uso de anticuerpos policlonales equinos (EpAbs) es otra alternativa terapéutica interesante. La nueva generación de EpAbs incluyen el procesamiento y purificación de los mismos y la obtención de fragmentos F(ab’)2 con alta pureza y un excelente perfil de seguridad en humanos. Los EpAbs son fáciles de producir, lo cual permite el desarrollo rápido y la elaboración a gran escala de un producto terapéutico. En este trabajo mostramos el desarrollo de un suero terapéutico obtenido luego de la inmunización de caballos utilizando el receptor-binding domain de la glicoproteína Spike del virus. Nuestro producto mostró ser alrededor de 50 veces más potente en ensayos de seroneutralización in vitro que el promedio de los plasmas de convalecientes. Estos resultados nos permitirían testear la seguridad y eficacia de nuestro producto en ensayos clínicos de fase 2/3 a realizarse a partir de julio de 2020 en la zona metropolitana de Buenos Aires, Argentina.

Comparação da efetividade de diferentes propostas de reabilitação vestibular / Comparison of the effectiveness of different vestibular rehabilitation proposals

Introdução: muitos dos pacientes que chegam para avaliação ou tratamento dos transtornos do equilíbrio queixam-se de tontura; não sabendo diferenciá-los e, na maioria das vezes, tendo a falsa ideia de que apresentam um quadro de "labirintite", o qual não tem cura, buscam apenas uma medicação para aliviar seus sintomas. Objetivo: comparar a efetividade de 3 propostas de Reabilitação Vestibular (RV): protocolo de Cawthorne-Cooksey, protocolo Italiano e personalizado. Métodos: participaram 105 indivíduos entre 30 e 59 anos, submetidos ao diagnóstico otoneurológico e separados em 3 grupos com médias de idades semelhantes. O grupo 1 foi composto por 30 participantes tratados com o protocolo de Cawthorne-Cooksey; o grupo 2 por 45 pacientes e foi usado o protocolo Italiano, e o grupo 3 por 30 indivíduos tratados com a proposta personalizada. A efetividade da RV foi avaliada pelo escore do Dizziness Handicap Inventory ­ DHI, adaptado para português, no pré-tratamento, momento da alta ou, no máximo, após 12 sessões de RV. Resultados e Discussão: as principais queixas foram de tonturas e desequilíbrio. Todos os pacientes foram diagnosticados com Síndrome Vestibular Periférica Irritativa ou Deficitária. Todos tiveram desaparecimento ou diminuição de seus sinais e sintomas, sendo que apenas um não atingiu a diminuição preconizada pelo DHI. Quanto às escalas emocional, física e funcional mensuradas pelo DHI, não houve diferença na pontuação em nenhum dos grupos e nem na comparação entre as três escalas no momento pós, caracterizando que a melhora ocorreu proporcionalmente nos três aspectos. Conclusão: o estudo não evidenciou diferença significativa entre as propostas de RV utilizadas.

Introduction: many of the patients who come for evaluation or treatment of balance disorders complain of dizziness; not knowing how to differentiate them, and most of the time they have the false idea that they have a "labyrinthitis" picture, which has no cure, they seek only a medication to relieve their symptoms. Objective: to evaluate the effectiveness of different proposals of VR: protocol of Cawthorne- Cooksey, Italian and customized protocol. Method: for this study, 105 individual between 30 and 59 years were submitted to the otoneurological diagnostic and divided in three groups with similar age average. Group 1 consisted of 30 participants treated with the Cawthorne-Cooksey protocol; group 2, by 45 participants, treated with the Italian protocol and group 3, by 30 participants, treated through the Individualized proposal. The effectiveness of VR was evaluated by the Dizziness Handicap Inventory - DHI score, adapted to Portuguese, at pre-treatment, discharge or at most after twelve rehabilitation sessions. The main complaints were vertigo and instability. All patients had a diagnosis of Peripheral Irritative or Deficient Vestibular Syndrome. Results and Discussion: all of them presented disappearance or decrease of their signs and symptoms, and only one of which didn`t reach the reduction recommended by DHI. As for the emotional, physical and functional scales measured by DHI, there was no difference in the scores in any of the groups nor in the comparison between the three scales at the post-moment, characterizing that the improvement occurred proportionally in all three aspects. Conclusion: the study did not show a significant difference between the VR proposals used.

Calidad higiénico-sanitaria en plantas de faena de la provincia de Tucumán: Detección, aislamiento y caracterización de Escherichia coli productor de toxina Shiga / Hygienic-sanitary quality in abattoirs from Tucuman province, Argentina: Detection, isolation and characterization of Shiga toxin-producing Escherichia coli

Los bovinos son el principal reservorio de Escherichia coli productor de toxina Shiga (STEC); las estrategias para evitar su transmisión se concentran en la planta de faena. El objetivo de este trabajo fue evaluar la calidad higiénico-sanitaria y la frecuencia de detección de STEC en medias reses bovinas de frigoríficos de tránsito provincial. Se procesaron 274 esponjados de media res; en 9 (3,3%) el recuento de E. coli genérico fue marginal, en 4 (1,4%) se aisló E. coli O157, de los cuales 2 fueron caracterizados como stx2c(vh-a)/eae/ehxA, y los otros 2 como no toxigénicos. A partir de una (0,4%) muestra se aisló E. coli no-O157 ONT:H49, stx2a/ehxA/saa. En este trabajo la calidad del producto analizado indica que en la provincia de Tucumán se cumplen las buenas prácticas de manufactura en la faena de bovinos.

Cattle are the main reservoir of Shiga toxin-producing Escherichia coli (STEC), and the strategies to prevent the transmission of these microorganisms are concentrated in the slaughtering plant. The aim of this study was to evaluate the hygienic-sanitary quality and the frequency of detection of STEC in beef carcasses in abattoirs from Tucuman province. Two hundred and seventy four beef carcass sponges were processed; the count of generic E. coli was marginal in 9 (3,3%) of them. Escherichia coli O157 was isolated in 4 (1,4%) samples; 2 of which were characterized as stx2c(vh-a)/eae/ehxA whereas the other 2 were non-toxigenic strains. Non-O157 E. coli ONT:H49, stx2a/ehxA/saa was isolated from 1 sample (0,4%). In this work the quality of the analyzed product indicates that the good practices of manufacture are fulfilled in slaughtering facilities in Tucumán province.

Microbiological and serological control of Escherichia coli O157: H7 in kindergarten staff in Buenos Aires city and suburban areas

Shiga toxin (Stx)-producing Escherichia coli (STEC) infections are implicated in the development of the life-threatening hemolytic-uremic syndrome (HUS). Despite the magnitude of the social and economic problems caused by HUS, no licensed vaccine or effective therapy is currently available for human use. Prevention of STEC infections continues being the most important measure to reduce HUS incidence. This is especially true for Argentina where HUS incidence among children is extremely high and shows an endemic pattern. The aim of this work was to investigate serologically adult staff of kindergartens in Buenos Aires city and suburban areas in order to detect possible carriers, and to educate personnel about good practices to reduce HUS transmission. We also assessed the microbiological quality of water and meal samples from the same kindergartens. We tested 67 healthy adults, 13 water supplies and 6 meals belonging to 6 public kindergartens. We analysed hand swabs for isolation of STEC and serum samples for the presence of antibodies against Stx and lipopolysaccharide (LPS) of O157 serogroup. We identified 46 Stx2-positive individuals, but only 7 for O157 LPS. No presence of STEC pathogens was detected in hands of staff, water or meal samples.

Las infecciones bacterianas con Escherichia coli productor de toxina Shiga (Stx) (STEC) están implicadas en el desarrollo del síndrome urémico hemolítico (SUH). A pesar de la magnitud del problema social y económico causado por el SUH, actualmente no existe un tratamiento específico o una vacuna eficaz para uso humano. Por lo tanto, la prevención de las infecciones por STEC es la tarea central para reducir la incidencia del SUH. Esto es especialmente cierto para Argentina en donde el SUH muestra un comportamiento endémico y presenta una incidencia extremadamente alta entre los niños. En efecto, la mediana de casos notificados en menores de 5 años para el periodo 2010-2015 fue 306, mientras que la tasa de notificación fue 8.5 casos cada 100 000 menores/año (http://www.msal.gob.ar/images/stories/boletines/boletin_integrado_vigilancia_N335-SE45.pdf). El objetivo de este trabajo fue analizar serológicamente al personal adulto de jardines de infantes de la ciudad de Buenos Aires y el área suburbana con el fin de detectar portadores, y brindarles formación sobre las buenas prácticas para reducir la transmisión de infecciones con STEC y así evitar el SUH. También se evaluó la calidad microbiológica de las muestras de agua y de la comida elaborada en los mismos jardines. Hemos estudiado 67 adultos, a través del hisopado de manos para la búsqueda de STEC y suero para la presencia de anticuerpos contra Stx y el lipopolisacárido (LPS) de serogrupo O157. También se analizaron 13 suministros de agua y 6 muestras de comida pertenecientes a 6 jardines de infantes públicos. Se identificaron 46 individuos positivos para Stx2, pero solo 7 para LPS-O157. No se detectó presencia de patógenos STEC en las muestras de las manos del personal, ni en los reservorios de agua o muestras de comida.

Daily meal frequency and associated variables in children and adolescents / Frequência de refeições diárias e variáveis associadas em crianças e adolescentes

Abstract: Objective: To investigate the frequency distribution of daily meals and its relation to demographic, socioeconomic, behavioral, anthropometric and biochemical factors in children and adolescents. Methods: This was a cross-sectional study with a representative sample of 708 schoolchildren aged 7-14 years. Data on personal information, socioeconomic status, physical activity and number of meals were obtained through semi-structured questionnaire and consumption by 24-h recall and food record. Weight and height measurements were also performed to calculate the body mass index. Finally, blood samples were collected for analysis of total cholesterol, high- and low density lipoprotein, triglyceride, and glucose levels. Descriptive statistics, the Mann-Whitney test, and Poisson regression were used in statistical analysis. Results: Meal frequency <4 was associated in children, family income <3 Brazilian minimum wages (PR = 5.42; 95% CI: 1.29-22.77; p = 0.021) and adolescents, the number of sons in the family >2 (PR = 1.53; 95% CI: 1.11-2.11; p = 0.010). Even in the age group of 10-14 years, <4 meals was related to higher prevalence of body mass index (PR = 1.33; 95% CI: 1.02-1.74; p = 0.032) and low-density lipoprotein (PR = 1.39; 95% CI: 1.03-1.87; p = 0.030) higher after adjustments. Conclusion: Lower frequency of meals was related to lower income in children and adolescents, larger number of sons in the family, and increased values of body mass index and low-density lipoprotein.

Resumo: Objetivo: Investigar a distribuição da frequência de refeições diárias e sua relação com fatores demográficos, socioeconômicos, comportamentais, antropométricos e bioquímicos em crianças e adolescentes. Métodos: Estudo transversal feito com uma amostra representativa de 708 escolares 7 e 14 anos. Os dados sobre informações pessoais, nível socioeconômico, atividade física e número de refeições foram obtidos por meio de questionário semiestruturado e o consumo por meio de recordatório de 24 horas e registro alimentar. Medidas de peso e altura também foram feitas para cálculo do índice de massa corporal. Por fim, coletaram-se amostras de sangue para análises de colesterol total, lipoproteína de baixa e de alta densidade, triglicerídeos e glicemia. Análises descritivas, teste de Mann-Whitney e regressão de Poisson foram usados nas análises estatísticas. Resultados: Frequência de refeições < 4 se associou, em crianças, a renda familiar < 3 salários (RP = 5,42; IC 95%: 1,29-22,77; p = 0,021) e, em adolescentes, ao número de filhos na família > 2 (RP = 1,53; IC 95%: 1,11-2,11; p = 0,010). Ainda na faixa de 10 a 14 anos, < 4 refeições se relacionou a maior prevalência de índice de massa corporal (RP = 1,33; IC 95%: 1,02-1,74; p = 0,032) e lipoproteína de baixa densidade (RP = 1,39; IC 95%: 1,03-1,87; p = 0,030) elevados após ajustes. Conclusão: Menor frequência de refeições se associou a menor renda em crianças e em adolescentes a maior número de filhos na família e valores aumentados de índice de massa corporal e lipoproteína de baixa densidade.

Función renal y nivel plasmático de dabigatrán en el valle, medido por un ensayo de trombina diluida / Renal function and plasma dabigatran level measured at trough by diluted thrombin time assay

El dabigatrán etexilato (inhibidor directo de trombina) es eficaz en la prevención tromboembólica en pacientes con fibrilación auricular. No requiere control rutinario de laboratorio, pero dada su eliminación renal, sería importante medirlo ante el deterioro de la función renal. Los objetivos del trabajo fueron verificar la calidad analítica del ensayo tiempo de trombina diluido para medición de la concentración plasmática (cc) de dabigatrán, correlacionar las cc con las pruebas básicas de coagulación tiempo de protrombina (TP) y tiempo de tromboplastina parcial activada (APTT) y evaluarlas de acuerdo al clearance de creatinina (CLCr). Se utilizaron muestras de plasma de 40 pacientes que recibían dabigatrán 150 (n = 19) o 110 (n = 21) mg/12 horas, colectadas 10-14 horas después de la última toma. Los ensayos de trombina diluida HemosIL DTI para la medición de dabigatrán, TP y APTT (IL), fueron realizados en coagulómetros fotoópticos ACL TOP 300 y 500 (IL). El DTI presentó coeficiente de variación intraensayo < 5.4% e interensayo < 6.0%, rango de linealidad 0-493 ng/ml; cc medidas en pacientes: mediana 83 (4-945) ng/ml. Individuos con CLCr en tercil inferior (< 46.1 ml/min) presentaron cc significativamente más elevadas, 308 (49-945), que los de tercilos medio, 72 (12-190), y superior, 60 (4-118) ng/ml. Las correlaciones cc vs. APTT o TP fueron moderadas, r2 = 0.59, -0.66, p < 0.0001, respectivamente. La prueba ensayada permitió cuantificar el nivel de dabigatrán plasmático tanto en pacientes con función renal normal como deteriorada, representando una herramienta útil en situaciones clínicas como deterioro de la función renal, pre cirugía o emergencias.

Dabigatran etexilate (direct thrombin inhibitor) is effective in preventing embolic stroke in patients with atrial fibrillation. It does not require laboratory control, but given the high renal elimination, its measurement in plasma is important in renal failure. The objectives of the study were to verify the analytical quality of the diluted thrombin time assay for measurement of dabigatran plasma concentration (cc), correlate cc with classic coagulation assays, prothrombin time (PT) and activated partial thromboplastin time (APTT), and evaluate them according to the creatinine clearance (CLCr). Forty plasma samples of patients (34 consecutive and 6 suspected of drug accumulation) receiving dabigatran at 150 (n = 19) or 110 (n = 21) mg/12 hours were collected. Blood samples were drawn at 10-14 hours of the last intake. Dabigatran concentration was determined by diluted thrombin time (HemosIl DTI, Instrumentation Laboratory (IL). PT and APTT (IL) were performed on two fotooptical coagulometers, ACL TOP 300 and 500 (IL). DTI presented intra-assay coefficient of variation < 5.4% and inter-assay < 6%, linearity range 0-493 ng/ml. Patients´ cc: median 83 (4-945) ng/ml. Individuals with CLCr in the lowest tertile (22.6-46.1 ml/min) showed significantly higher median cc: 308 (49-945), compared to the average 72 (12-190) and highest tertile, 60 (4-118) ng/ml. Correlation between cc and APTT or PT were moderate, r2 = 0.59 and -0.66, p < 0.0001, respectively. DTI test allowed us to quantify plasma dabigatran levels, both in patients with normal or altered renal function, representing a useful tool in clinical situations such as renal failure, pre surgery or emergencies.

Evolução do excesso de peso e obesidade até a idade adulta, Pelotas, Rio Grande do Sul, Brasil, 1982-2012 / Evolution of overweight and obesity into adulthood, Pelotas, Rio Grande do Sul State, Brazil, 1982-2012 / Evolución del exceso de peso y obesidad hasta la edad adulta, Pelotas, Rio Grande do Sul, Brasil, 1982-2012

Este trabalho analisou a prevalência de excesso de peso e obesidade na adolescência e idade adulta em indivíduos pertencentes a coorte de nascimentos de 1982, da cidade de Pelotas, Rio Grande do Sul, Brasil, segundo características sociais e demográficas. Em 1982, os nascimentos hospitalares que ocorreram na cidade de Pelotas foram identificados e os nascidos vivos (n = 5.914) cuja família residia na zona urbana da cidade têm sido acompanhados. No presente estudo, foram utilizados dados coletados aos 15, 18, 23 e 30 anos. Nas mulheres, a prevalência de excesso de peso aumentou de 23,6% aos 15 anos para 52,4% aos 30 anos, enquanto para a obesidade aumentou de 6,6% para 23,8%. Nos homens, o excesso de peso passou de 22,9% para 62,9%, enquanto para a obesidade o incremento foi de 7,5% para 22,1%. O incremento de excesso de peso e obesidade foi maior entre indivíduos com menor nível socioeconômico em ambos os sexos, o que pode levar ao aumento da desigualdade na ocorrência de doenças crônicas não transmissíveis.

This study assessed the prevalence of overweight and obesity in adolescence and adulthood among subjects enrolled in the 1982 Pelotas Birth Cohort, Rio Grande do Sul State, Brazil, according to social and demographic characteristics. In 1982, hospital births in Pelotas were identified and all live born infants (n = 5,914) were examined and have been followed since. The data were collected at 15, 18, 23, and 30 years of age. In women, prevalence of overweight increased from 23.6% at 15 years to 52.4% at 30 years of age, while obesity increased from 6.6% to 23.8%. In men, overweight increased from 22.9% to 62.9%, and obesity from 7.5% to 22.1%. Overweight and obesity increased more among individuals of both sexes with lower socioeconomic status, which can lead to more inequality in the occurrence of chronic diseases.

Este estudio examinó la prevalencia de exceso de peso y obesidad en la adolescencia y la edad adulta en los individuos de la cohorte de nacimientos de 1982, de la ciudad de Pelotas, Rio Grande do Sul, Brasil, de acuerdo a características sociales y demográficas. En 1982, se identificaron los nacimientos hospitalarios ocurridos en Pelotas y nacidos vivos (n = 5.914), a cuya familia residente en la zona urbana de la ciudad se le realizó un seguimiento. En este estudio se utilizaron los datos recogidos a los 15, 18, 23 y 30 años. En las mujeres, la prevalencia de exceso de peso aumentó de 23,6% a los 15 años a 52,4% a los 30 años, mientras que para la obesidad el aumento fue de un 6,6% a un 23,8%. En los hombres, el exceso de peso aumentó de un 22,9% a un 62,9%, mientras que para la obesidad, el aumento fue de un 7,5% a un 22,1%. El incremento de sobrepeso y obesidad fue mayor entre las personas con menor nivel socioeconómico en ambos sexos, lo que puede conducir a una mayor desigualdad en la aparición de enfermedades crónicas no transmisibles.

Aislamiento y caracterización de Escherichia coli O157 en productos cárnicos bovinos y medias reses en la provincia de Tucumán / Isolation and characterization of Escherichia coli O157 in bovine meat products and cattle in the province of Tucuman

Escherichia coli O157 es un patógeno emergente asociado a diarrea, colitis hemorrágica y síndrome urémico hemolítico. Los productos cárnicos constituyen una importante fuente de contaminación con este microorganismo. Los objetivos de este estudio fueron establecer la frecuencia de detección de E. coli O157 en productos cárnicos y media res en la provincia de Tucumán, caracterizar los factores de virulencia de los aislamientos obtenidos, establecer la relación clonal entre cepas regionales mediante electroforesis de campo pulsado y comparar con lo consignado en la base de datos nacional. Desde 2004 hasta 2013 se analizaron 169 muestras de carne picada, 35 embutidos y 216 esponjados de media res. Se identificaron 13 aislamientos de E. coli O157; 6 de ellos fueron O157:H7 productores de toxina Shiga y se caracterizaron como stx2c(vh-a)/eae/ehxA (n = 5) y stx2/eae/ehxA (n = 1); los 7 aislamientos de E. coli O157 no toxigénicos fueron O157:NT(n = 4),O157:NM (n = 1),O157:ND (n = 1) y O157:H16 (n = 1). Los patrones de PFGE fueron diferentes entre sí y de los registrados en la base de datos nacional. Se concluye que existe gran diversidad genética en los aislamientos de E. coli O157 circulantes en nuestra región

Escherichia coli O157 is an emergent pathogen associated with diarrhea, hemorrhagic colitis and hemolytic uremic syndrome. Meat products constitute an important transmission source of this microorganism. The aims of this study were to characterize E. coli O157 isolated from cattle and meat products collected from abattoirs and retail stores, to establish the clonal relatedness among regional isolates and to compare them with those in the national database. Between 2004 and 2013, 169 minced meat, 35 sausage and 216 carcass samples were analyzed. Thirteen E. coli O157 isolates were identified; 6 of which were O157:H7 and characterized as stx2c(vh-a)/eae/ehxA (n = 5) and stx2/eae/ehxA (n = 1). The 7 remaining isolates were non-toxigenic E. coli strains, and serotyped as O157:NT (n = 4), O157:NM (n = 1), O157:ND (n = 1) and O157:H16 (n = 1). The strains yielded different XbaI-PFGE patterns. Compared to the E. coli O157 isolates in the National Database, none of these patterns have been previously detected in strains of different origin in Argentina
