Uso de ibuprofeno en el tratamiento de pacientes pediátricos con poliuria y disnatremia. Reporte de una serie de casos / Ibuprofen use for the treatment of pediatric patients with polyuria and dysnatremia. A case series report

Los niños con lesiones selares y/o supraselares pueden presentar diabetes insípida central con posterior secreción inadecuada de hormona antidiurética. Nosotros observamos, en algunos casos, aumento de la incidencia de poliuria, natriuresis e hiponatremia, tríada diagnóstica del síndrome cerebral perdedor de sal. Aquí comunicamos la evolución de 7 pacientes con antecedentes de daño agudo del sistema nervioso central y diabetes insípida central seguida por síndrome cerebral perdedor de sal. Como tratamiento aportamos secuencialmente fluidos salinos parenterales, cloruro de sodio oral, desmopresina, mineralocorticoides e incluso tiazidas. Ante la persistencia de poliuria con hiponatremia, agregamos ibuprofeno. Como resultado de este esquema terapéutico secuencial, este grupo redujo significativamente los valores de diuresis diaria de 10 ml/kg/h a 2 ml/kg/h en un tiempo promedio de 5 días, normalizando también las natremias (de 161 mEq/L a 143 mEq/L) en un tiempo promedio de 9 días. En ningún caso observamos efectos adversos asociados al tratamiento.

Children with sellar and/or suprasellar lesions may develop central diabetes insipidus with subsequent inappropriate antidiuretic hormone secretion. An increased incidence of polyuria, natriuresis, and hyponatremia has been reported in some cases, which make up the diagnostic triad of cerebral salt wasting syndrome. Here we report the clinical course of 7 patients with a history of acute central nervous system injury and central diabetes insipidus followed by cerebral salt wasting syndrome. Treatment included the sequential use of parenteral saline solution, oral sodium chloride, desmopressin, mineralocorticoids, and even thiazides. Due to persistent polyuria and hyponatremia, ibuprofen was added. As a result of this sequential therapeutic regimen, daily urine output reduced significantly from 10 mL/ kg/h to 2 mL/kg/h over an average period of 5 days, together with a normalization of natremia (from 161 mEq/L to 143 mEq/L) over an average period of 9 days. No treatment-related adverse effects were observed in any case.

Main results and public health implications of the National School Health Survey (ENSE), Colombia 2017

Introduction: The school population represents a fundamental group for health promotion actions, given that the foundations of healthy behaviors in adult life are established in children and adolescents, who can be greatly influenced by the school. Objective: To describe the health-related behavioral factors of schoolchildren between 13 and 17 years of age in secondary and middle school in Colombia. Methods: A national cross-sectional study was conducted (i.e., School Health Survey -ENSE-) that recorded information on dietary practices, physical activity, alcohol and drug consumption, injuries and bullying, and oral, visual and hearing health. Sampling was probabilistic, cluster and multistage. Results: Schoolchildren have low consumption of fruits, vegetables (13.1%) and dairy (76.5 %), high consumption of ultra-processed foods (82.4 %), sugary drinks (74.0 %) and fast foods (14.8 %), frequent addition of salt at the table (43.3 %), low compliance with physical activity recommendations (15.0 %) and high sedentary lifestyle (46.3 %), frequent consumption of alcohol (44.7 %) and psychoactive substances (14.7 %), in addition to prevalent situations of bullying (15.4 %), rejection (8.2 %) and verbal aggression (42.7 %). Conclusions: The ENSE shows critical inequalities by gender, ethnicity and social class, throughout the country. The indicators observed in schoolchildren are precursors of various chronic and degenerative diseases and mental illness, which requires the urgent attention of the different social actors in the country.

The frequency of patients with calcium stones was higher in those with increased sodium excretion (78.3%) and in those with hypercalciuria (83.3%), in contrast with the frequencies of this type of lithiasis, in those who did not present these disorders (p=0.03 in both cases). Conclusions: The most common urolithiasis in Cuban adults are calcium ones, especially those of calcium oxalate. The most common metabolic disorders are: increased urinary sodium excretion, low urinary volume and acid urinary pH. The presence of calcium lithiasis is related to increased urinary sodium excretion and hypercalciuria.

Feeding behavior of lambs fed diets containing old man saltbush hay / Comportamiento ingestivo de corderos alimentados con dietas conteniendo heno de hierba-sal / Comportamento ingestivo de cordeiros alimentados com dietas contendo feno de erva-sal

Abstract Background: We hypothesized that a diet with old man saltbush hay used as an alternative source of nutrients could partially replace the concentrate in the feeding of feedlot lambs. Objective: This study evaluated the behavior and performance of lambs fed diets containing increasing levels of old man saltbush hay plus concentrate. Methods: Twenty-four castrated Santa Inês lambs at approximately eight months of age (22 ± 1.97 kg) were confined in a randomized complete design and fed diets containing 30, 40, 50, and 60% (dry matter: DM) of old man saltbush hay. Results: The intake of DM and neutral detergent fiber was not affected (p>0.05) by the level of old man saltbush hay. Intake of mineral salt decreased (p<0.01) as the proportion of old man saltbush in the diet increased. Weight gain (kg) and feed efficiency worsened (p<0.05) with 40% inclusion of old man salt bush hay. The time spent on feeding and chewing increased (p<0.05), while idle time was reduced (p<0.01) with dietary inclusion of old man saltbush. Feed efficiency decreased (p<0.05) with the inclusion of old man saltbush. Conclusion: Dietary inclusion of old man saltbush affects the feeding behavior and performance of lambs in feedlot.

Resumen Antecedentes: Nuestra hipótesis consistió en que una dieta con heno de hierba-sal como fuente alternativa de nutrientes puede sustituir parcialmente el concentrado en la alimentación de corderos confinados. Objetivo: Evaluar el comportamiento ingestivo de corderos alimentados con dietas conteniendo niveles incrementales de heno de hierba-sal asociado al concentrado. Métodos: Veinticuatro corderos Santa Inés, castrados, con aproximadamente ocho meses de edad, peso corporal de 22 ± 1,97 kg, confinados, fueron distribuidos en un arreglo experimental completamente aleatorizado y alimentados con dietas conteniendo 30, 40, 50 y 60% (materia seca: MS) de heno de hierba-sal.

Abstract This study was carried out in the laboratory of Shangqiu Institute of Technology, Henan to investigate the effect of a different combination of inorganic salt on the quality and physiological characteristics of cut flowers (CFs) of Perpetual Carnation. Furthermore, to find out the best preservation solution of inorganic salt that can enhance the ornamental value of CFs of Carnation and prolong its vase life. Sucrose, 8-hydroxyquinoline, paclobutrazol, salicylic acid and different kinds of inorganic salts were added as a preservation solution. And the same amount of distilled water was used as control. The effects of these various inorganic salts on the morphological characteristics including vase life, changes in flower stems, fresh weight (FW) and water balance and the physiological characteristics including contents of malondialdehyde (MDA), cell membrane permeability and the contents of proline of carnation were investigated. The CFs placed in vase solution with inorganic salts showed significant changes in its morphology and physiological characteristics as compared to control. The changes in flower diameter (FD), FW, malondialdehyde and cell membrane permeability showed an increasing trend first and then decreasing. The value of water balance was observed with a downward trend. However, the vase life, FD, the contents of malondialdehyde, contents of proline and FW of CFs held in the preservative solution containing inorganic salts were increased than that of control. The fresh preservative solution contained sucrose 3% + 8-hydroxyquinoline (8-HQ) (200 mg·L‾1) + paclobutrazol (100 mg·L‾1) + salicylic acid (SA) (25 mg·L‾1) + CaCl2 (100 mg·L‾1) has the best effect on longevity (34 days), FW and FD of carnation CFs. This solution has improved the ornamental and physiological characteristics of fresh carnation CFs.

Diseases of the central nervous system in swine in Southern Brazil / Doenças do sistema nervoso central de suínos no Sul do Brasil

Brazil is the fourth largest exporter of pork worldwide, with its production concentrated in the Southern region of the country. To reduce the economic impacts and increase herd health, an efficient diagnosis of diseases is necessary. The frequency, seasonal, and annual distribution of diseases that affecting the swine nervous system in Southern Brazil were determined through a retrospective study conducted from 2008 to 2018. A total of 231 pigs were evaluated, and distributed in the following phases: suckling piglets, nursery, growing, finishing, and adults. Piglets in the nursery phase were the most affected with 58.01%. Infectious diseases accounted for 87.01% (201/231) of lesions in the nervous system. Bacterial meningitis was observed in 58.87% of cases, presenting an endemic distribution, and a propensity to occur in the months of autumn/winter. The highest number of cases of porcine circovirus-2 were observed in 2008 and 2009, with a subsequent decline. Porcine circovirus, salt poisoning, and brain abscesses exhibited no association between the seasonal occurrence and annual distribution. Salt poisoning was observed more frequently in the last years of this study. Both, non-suppurative encephalomyelitis and selenium toxicosis exhibited an association between their occurrence and seasonal distribution in, the months of winter, and summer, respectively.(AU)

Glyphosate-resistant soybeans yield in function of glyphosate salts, doses and stadium phenological / Produtuvidade de cultivares de soja em função dos sais de glyphosate, doses e épocas de aplicação

Given the importance of soybean to the global economy and as a food source, improving crop management techniques is integral to obtaining higher yields. As such, this study aimed to assess the yield of soybean cultivars as a function of different glyphosate salt formulations, doses and application times. Two field experiments were conducted simultaneously using a randomized block design and 3x4x2 factorial scheme, with three repetitions. Factor A consisted of three glyphosate formulations: isopropylamine salt (Roundup Original®), ammonium salt (Roundup WG®), and potassium salt (Zapp Qi®), factor B four application times: 0, 14, 28, 42 days after planting (DAP), and factor C two doses: the recommended dose of 720 grams of acid equivalent per hectare and twice that (1440 grams of acid equivalent per hectare). There was no difference between the glyphosate salts for the BMX Ativa RR® cultivar, but yields of BMX Apolo RR® submitted to ammonium salt were 28% higher than those recorded for the other salts studied. Glyphosate potassium salt resulted in lower soybean yields. Potassium salt application between 14 and 28 DAP caused greater toxicity in both the soybean cultivars analyzed.

Diante da importância da cultura da soja tanto na economia mundial quanto para a alimentação, a melhoria das técnicas de cultivo torna-se um ponto fundamental na obtenção de maiores produtividades. Desta forma o objetivo do trabalho foi avaliar a produtividade de cultivares de soja sob a influência da aplicação de diferentes sais de glyphosate, doses e épocas de aplicação. Dois experimentos de campo foram realizados simultaneamente em delineamento de blocos casualizados com arranjo trifatorial (3x4x2) com três repetições. O fator A consistiu de três formulações de glyphosate: sal de isopropilamina (Roundup Original®), sal de amônio (Roundup WG®), sal de potássio (Zapp Qi®). O fator B consistiu de quatro épocas de aplicação: 0, 14, 28, 42 dias após a semeadura (DAS). O fator C consistiu em duas doses: a dose recomendada de 720 gramas de equivalente ácido por hectare e duas vezes a dose recomendada com 1440 gramas de equivalente ácido por hectare. Para a cultivar BMX Ativa RR® não se observou diferença quanto aos sais, porém a cultivar BMX Apolo RR® submetida a aplicação de sal de amônio demostrou uma produtividade 28% superior em relação aos demais sais. O glyphosate na formulação sal de potássio apresentou redução da produtividade da cultura da soja. Aplicações de glyphosate na formulação sal de potássio realizadas entre os 14 e 28 dias após a semeadura causam maior toxidez em ambas cultivares de soja utilizadas.

Las hormonas femeninas en fisiología renal: Sensibilidad a la sal y regulación de la proliferación epitelial / Female hormones in renal physiology. Salt sensitivity and regulation of epithelial proliferation

Un tercio de la población mundial tiene niveles anormalmente altos de presión arterial, hipertensión, responsable de casi el 50% de las muertes por accidente cerebrovascular y enfermedad coronaria. La sensibilidad a la sal es un factor de riesgo para la morbilidad y mortalidad cardiovascular y también para otras enfermedades. En estudios previos describimos un modelo de hipertensión sal sensible (HSS) en ratas Wistar ovariectomizadas (oVx) adultas. Las ratas oVx son normotensas con ingesta normal de sal (NS, 0.24% de NaCl), pero desarrollan un perfil de HSS con una ingesta elevada de sal (HS, 1% de NaCl). En los estudios en riñón encontramos que el circuito receptor D1 de dopamina, citocromo P450 4A y Na+, K+-ATPasa está alterado por la ausencia de hormonas ováricas, lo que se asocia a menor excreción de sodio e hipertensión arterial. La ingesta HS en ratas oVx también promueve cambios en la expresión de proteínas relacionadas con el transporte de sodio en células mononucleares de sangre periférica, principalmente linfocitos periféricos. Por lo tanto, el transporte de sodio se modifica en varios niveles de la fisiología normal. En estudios recientes observamos que el estradiol aumenta la proliferación y diferenciación de células epiteliales en cultivos de corteza renal humana. Sensibilidad a la sal, inmunidad adaptativa, presión arterial y proliferación de células epiteliales en riñón son fenómenos de gran importancia biológica regulados por estradiol.

Female sex hormones participate in the regulation of blood pressure and renal epithelial proliferation, effects not related to their reproductive function. About one-third of the world's population has abnormally high levels of blood pressure, hypertension, which is responsible for almost 50% of deaths from stroke and coronary heart disease. Salt sensitivity is a risk factor for cardiovascular morbidity and mortality and other diseases as well. We reported a model of salt sensitive hypertension in adult ovariectomized (oVx) Wistar rats. oVx rats are normotensive under normal salt intake (NS, 0.24% NaCl), but upon a high salt intake (HS, 1% NaCl) oVx rats developed a blood pressure profile of salt-sensitive hypertension. Our studies on kidney molecules related to sodium balance found that the circuit dopamine D1-like receptor, cytochrome P450 4A and Na+, K+-ATPase is altered by the absence of ovary hormones which is accompanied by a reduced ability to excrete sodium. In oVx rats HS intake also promotes changes in the expression of proteins related to sodium transport in peripheral blood mononuclear cells, mainly peripheral lymphocytes. Therefore, sodium transport is modified at several levels of normal physiology. Lately, we described that estradiol increases the rate of renal epithelial cell proliferation in primary cultures developed from human renal cortex. Thus, salt sensitivity, adaptive immunity, blood pressure and renal cell proliferation are complex biological responses regulated by female sex hormones.

Salidroside regulates DC through TLR4 to increase the lethality of T cells to lung cancer 3LLcells / 中国肿瘤生物治疗杂志

@#Objective： ：To investigatetheeffectofsalidroside(SAL)onthephenotype of dendritic cells (DCs) and the antitumor ability of cytotoxic T lymphocytes (CTL). Methods： ：Lewis lung cancer cell line 3LL, wild type (WT) C57BL/6 mice and TLR4-/- C57BL/6 mice were chosen for this study. Mice bone marrow derived DC precursor cells were obtained to differentiate into immature DCs, which were harvested on the sixth day of culture. CD11c+ DCs were obtained by magnetic beads screening, and further divided into PBS group, SAL group and lipopolysaccharide (LPS) group.After being cultured for 48 h, the effects of SAL on surface molecules and phagocytosis of DCs as well as the efffect of TLR4 pathway on the killing effect of T cells were detected by Fow cytometry. Results： ： Compared with PBS group, expressions of DC surface molecules CD80, CD86 and MHC Ⅱ significantly increased (all P<0.05), phagocytosis significantly decreased (P<0.05), and TLR4 expression level significantly increased (P<0.01) in SAL group; Compared with WT group, after being treated with SAL or LPS, the expressions of DC surface molecules CD80, CD86 and MHC Ⅱ decreased significantly in TLR4-/- group (all P<0.05); ComparedwithPBSgroup,theactivatedCTLinSALgroupexhibited a significantly elevated killing effect against lung cancer 3LLcells (P<0.05). Conclusion：SAL can induce DC maturation by regulating TLR4, thus improving the killing ability of T cells.

Relación entre la microbiota del intestino y la tensión arterial / Relationship between intestinal microbiota and blood pressure

Se ha demostrado la asociación de los microbios intestinales Firmicutes y Bacteroidetes con la hipertensión arterial, inclusive en personas sensibles a la sal. Asimismo, la disminución de la microbiota por los antibióticos puede aumentar o disminuir la tensión arterial acorde a la influencia del genotipo. En este artículo se comunican algunos argumentos sobre el tema y, además, se explica cómo la función biológica de los probióticos también puede ser el resultado de modificaciones epigenéticas, relacionado, en parte, con el micro-ARN, y cómo los productos de la fermentación de los nutrientes por la microbiota pueden influir en la tensión arterial regulando el gasto energético, el metabolismo intestinal de las catecolaminas, el transporte iónico gastrointestinal y renal y, con ello, la sensibilidad a la sal. Por último, se concluye que el efecto beneficioso o deletéreo de la microbiota intestinal sobre la tensión arterial es una consecuencia de distintas variables, incluidas las genéticas y epigenéticas, así como el estilo de vida y el uso de antibióticos.

The association of Firmicutes and Bacteroidetes intestinal microbes with hypertension has been demonstrated, including people sensitive to salt. Also, the microbiota decrease due to antibiotics can increase or diminish the blood pressure according to the genotype influence. Some arguments on the topic are communicated in this work and, also, it is explained how the biological function of probiotics can also be the result of epigenetics modifications, related, to some extent, to the micro-RNA, and how the nutrients fermentation products due to microbiota can influence in blood pressure regulating the energy expense, intestinal metabolism of catecholamines and gastrointestinal and renal ionic transportation, and with it the sensibility to salt. Lastly, it is concluded that the beneficial or deleterious effect of intestinal microbiota on blood pressure is a consequence of different variables, including genetics and epigenetics variables, as well as lifestyle and use of antibiotics.

Salt Preference is Linked to Hypertension and not to Aging / A Preferência ao Sal está Relacionada à Hipertensão e não ao Envelhecimento

Abstract Background: Seasoning is one of the recommended strategies to reduce salt in foods. However, only a few studies have studied salt preference changes using seasoning. Objectives: The aim of this study was to compare preference for salty bread, and if seasoning can change preference in hypertensive and normotensive, young and older outpatients. Methods: Outpatients (n = 118) were classified in four groups: older hypertensive subjects (OH) (n = 32), young hypertensive (YH) (n = 25); older normotensive individuals (ON) (n = 28), and young normotensive (YN) (n = 33). First, volunteers random tasted bread samples with three different salt concentrations. After two weeks, they tasted the same types of breads, with seasoning added in all. Blood pressure (BP), 24-hour urinary sodium and potassium excretion (UNaV, UKV) were measured twice. Analysis: Fisher exact test, McNamer's test and ANCOVA. Statistical significance: p < 0.05. Results: Systolic BP, UNaV, and UKV were greater in HO and HY and they had a higher preference for saltier samples than normotensive groups (HO: 71.9%, HY: 56% vs. NO: 25%, NY; 6%, p<0.01). With oregano, hypertensive individuals preferred smaller concentrations of salt, with reduced choice for saltier samples (HO: 71.9% to 21.9%, and HY: 56% to 16%, p = 0.02), NO preferred the lowest salt concentration sample (53.6% vs. 14.3%, p < 0.01), and NY further increased the preference for the lowest one (63.6% vs. 39.4%, p = 0.03). Conclusions: Older and younger hypertensive individuals prefer and consume more salt than normotensive ones, and the seasoned bread induced all groups to choose food with less salt. Salt preference is linked to hypertension and not to aging in outpatients.

Resumo Fundamento: Adicionar temperos aos alimentos é umas das estratégias recomendadas para diminuir a quantidade de sal nos alimentos. No entanto, poucos estudos investigaram alterações na preferência ao sal através do uso de temperos. Objetivos: O objetivo deste estudo foi comparar a preferência pelo pão salgado, e até que ponto o uso de temperos pode alterar as preferências dos indivíduos hipertensos e normotensos, pacientes ambulatoriais jovens e idosos. Métodos: Os pacientes ambulatoriais (n = 118) foram classificados em quatro grupos: idosos com hipertensão (IH) (n = 32), jovens hipertensos (JH) (n = 25); indivíduos idosos normotensos (IN) (n = 28), e jovens normotensos (JN) (n = 33). Primeiro, os voluntários provaram amostras aleatórias de pão com três diferentes concentrações de sal. Após duas semanas, eles provaram os mesmos tipos de pão, porém acrescidos de temperos. A pressão arterial (PA), e a excreção urinária de sódio e potássio de 24 horas (UNaV, UKV) foram medidas duas vezes. Análise: Teste exato de Fisher, teste de McNemar e teste ANCOVA. Significância estatística: p < 0,05. Resultados: A PA sistólica e a excreção urinária de sódio e potássio foram maiores nos grupos IH e JH, e eles tiveram maior preferência por amostras mais salgadas quando comparados com os grupos de normotensos (IH: 71,9%, JH: 56% vs. IN: 25%, JN; 6%, p < 0,01). Quando o orégano foi adicionado, a preferência dos indivíduos hipertensos foi pelas amostras com menores concentrações de sal, com uma diminuição da escolha por amostras mais salgadas (IH: 71,9% a 21,9%, e JH: 56% a 16%, p = 0,02); o grupo IN preferiu a amostra com a concentração de sal mais baixa (53,6% vs. 14,3%, p < 0,01) e no grupo JN aumentou ainda mais o número de indivíduos com preferência pela amostra com concentrações mais baixas de sal (63,6% vs. 39,4%, p = 0,03). Conclusões: Os idosos e jovens hipertensos preferem e consomem mais sal do que os normotensos, e o pão adicionado de tempero ajudou todos os grupos a escolher alimentos menos salgados. A preferência ao sal está ligada à hipertensão e não à idade nos pacientes ambulatoriais.

Avaliação sensorial de lombos defumados elaborados com carne suína de diferentes qualidades e com teor reduzido de sal / Sensory assessment of smoked loin elaborated with different pork qualities and with reduced salt content

Objetivou-se avaliar a aceitação sensorial e a percepção de ideal de sal de lombos suínos defumados elaborados com carnes de diferentes classes de qualidade (RFN, PSE e DFD) e diferentes concentrações de sal (1,2 e 1,8%). As notas de aceitação do sabor (nota 6,53) e da impressão global (nota 6,69) não foram afetadas (P>0,05) pelos fatores, mas os consumidores preferiram a aparência das amostras adicionados de 1,8% de sal, independentemente da qualidade da carne. Amostras RFN com 1,8% de sal tiveram a textura mais aceitas do que as com 1,2% de sal e amostras PSE com 1,8% foram consideradas com ideal de sal quando comparado às PSE com 1,2% de sal. Conclui-se que diferentes classes de qualidade e teores de sal afetam a aceitação dos lombos defumados, mas estes ainda possuem uma boa aceitação sensorial por parte dos consumidores.
