ABSTRACT

Abstract On the increasing prevalence of using mAbs (monoclonal antibodies) in cancer therapy and the severe risk of hyperglycemia, we aimed to analyze the main clinical ADRs of mAbs, with a focus on adverse hyperglycemic events associated with currently clinically used mAbs. mAbs as well as target information were selected from Martinadale book and published articles. Drug approving information was collected from each government website, and ADR statistic data were collected from VigibaseR, comparing with Adverse Event Reporting System of US FDA. Top 10 mAbs were classified within listing in total ADR records, ADRs per year, hyperglycemic ADR records. Vigibase data were updated onto 15 Feb 2019. 20 mAbs were analyzed with 263217 ADR reports, wherein 16751 records on Metabolism and nutrition disorders and 1444 records on Glucose metabolism disorders. The geographic, age, gender distributions and annual ADR report numbers were listed respectively. Of the top 10, Rituximab, Bevacizumab and Nivolumab were on the top 3 in total ADR record and hyperglycemic record. Top 3 record results were similar in Vigibase and FDA database. It is of increasing importance for clinicians to be aware of early detection, patient management, or drug selection strategies when using mAbs, particularly within the high glycemic risk-reported mAbs, to improve the efficacy and tolerability of mAbs regiment and optimize patient outcomes.

ABSTRACT

The objective was to evaluate the antioxidant capacity, glucose and insulin concentration and reproductive performance of ewes supplemented with orange residue prior to insemination. Fifty-five multiparous ewes were divided into two corrals, and 15 unbred ewes were kept individually to measure feed consumption. Two integral diets were administered; T0: control treatment and T1: with 20% of dry matter of orange residue. Ten days after the start of supplementation, the ewes were synchronized. Supplementation was finalized prior to artificial insemination, then, a blood sample was taken to measure the antioxidant capacity and glucose and insulin concentration. An analysis of variance was made to evaluate the effect of treatment on the antioxidant capacity, glucose and insulin; and to analyze the response to estrus, percentage of gestation and prolificity a ji squared test was performed. Of 9 antioxidant compounds found in the orange residue, hesperidin (7.44%), chlorogenic acid (0.50%) and protocatechuic acid had the highest concentration. Feed intake, estrus response, percentage of gestation, antioxidant capacity, and glucose and insulin concentration were not affected by the treatment. It is concluded that inclusion of 20% of orange residue in the diet prior to insemination in ewes is possible.(AU)


O objetivo deste estudo foi avaliar a capacidade antioxidante, a concentração de glicose e insulina e o comportamento reprodutivo de ovelhas suplementadas com resíduo de laranja antes da inseminação. Cinquenta e cinco ovelhas multíparas foram divididas em dois currais e 15 ovelhas sem raça foram mantidas individualmente para se medir o consumo de ração. Duas dietas integrais foram administradas; T0: tratamento controle e T1: dieta com 20% de resíduo de laranja seco. Dias após o início da suplementação, as ovelhas foram sincronizadas. A suplementação foi finalizada antes da inseminação artificial e, em seguida, foi coletada uma amostra de sangue para medir a capacidade antioxidante e a concentração de glicose e insulina. Uma análise de variância foi feita para avaliar o efeito do tratamento sobre a capacidade antioxidante, a glicose e a insulina, e um teste do ji quadrado foi realizado para analisar a resposta ao estro, a porcentagem de gestação e de prolificidade. Dos nove compostos antioxidantes encontrados no resíduo laranja, a hesperidina (7,44%), o ácido clorogênico (0,50%) e o ácido protocatecuico foram os de maior concentração. O consumo alimentar, a resposta ao estro, a porcentagem de gestação, a capacidade antioxidante, a concentração de glicose e a insulina não foram afetados pelo tratamento. Conclui-se que é possível a inclusão de 20% de resíduos de laranja na dieta antes da inseminação em ovelhas.(AU)

ABSTRACT

ABSTRACT Introduction Diabetes is a metabolic disease characterized by hyperglycemia. It is a metabolic syndrome in which blood sugar levels increase due to defects in insulin secretion or impaired function, or even both defects. Object To understand the effect of diabetic patients in controlling blood sugar through physical exercise, the paper analyzes the correlation between the exercise status and physiological indicators of diabetic patients in our hospital. Methods We randomly selected 41 diabetic patients and monitored their exercise. At the same time, we check the physiological indicators of the patients after the exercise is completed and analyze the control of blood sugar by sports. Results After healthy physical exercise, the blood sugar level of diabetic patients tended to stabilize, and the glycosylated hemoglobin level decreased. The blood sugar levels of patients who did not participate in healthy physical exercises were not stable, and their glycosylated hemoglobin levels did not improve. Conclusion Healthy sports is a simple, easy, safe and effective adjuvant therapy for the prevention and treatment of diabetes, and it is worthy of clinical promotion. Level of evidence II; Therapeutic studies - investigation of treatment results.

ABSTRACT

ABSTRACT Introduction: According to the metabolic characteristics of ultra-long-distance swimming and the characteristics of energy utilization and absorption during exercise, we have formulated a nutritional supplement plan for crossing to study the influence of swimming sports on blood sugar and give biochemical feedback indicators. Objective: To lay a foundation for studying the nutrition supplement rules during long-term exercise by taking the athletes' blood after training to determine the changes in blood sugar, adjusting and determining the nutritional supplement plan during training. Methods: We monitor athletes' physical function changes and biochemical indicators during training and study the changes of these biochemical indicators and athletes' physical functions after long-term swimming exercises to scientifically arrange the exercise intensity and load during the training period. Results: The urine indexes after exercise did not change much, reflecting the exercise load's low intensity. The changes in blood lactic acid and blood urea indexes after exercise also confirmed this. During the training period, the athletes' hemoglobin and red blood cell parameters are in the ideal range, indicating that the athlete's physical function is in good condition. During the training period, the training load intensity and load are reasonable according to ultra-long-distance swimming's energy supply characteristics. After training, the changes in blood glucose indicators reflect that the nutritional supplement program we formulated for athletes is reasonable and feasible. Conclusions: By monitoring the blood sugar and biochemical indicators of swimmers, it can help athletes to arrange exercise intensity scientifically and load during the training period, to better carry out open water competitions in China, and to arrange training and scientific nutrition during the training period scientifically. Lay the foundation for the establishment of nutrition supplement theory and training theory for super long-time sports. Level of evidence II; Therapeutic studies - investigation of treatment results.

ABSTRACT

ABSTRACT Introduction It is known that strength training brings improvements in health and sports performance by causing muscle hypertrophy and increased strength, as well as modifying some hemodynamic and physiological factors. Several strength training methodologies have been developed, one of which is vascular occlusion. There are few studies with large muscle groups due to poor adherence to the training style and the fact that vascular occlusion of large muscle groups is more difficult. Objective To verify and compare the hemodynamic effects of exercise with and without vascular occlusion in different muscle groups. Methods Quantitative crossover study, with cross-sectional and field procedures. The sample consisted of 10 physically active healthy male and female subjects between 18 and 30 years of age. With the cross-over design, all the volunteers participated in 3 groups: intervention with vascular occlusion, intervention without vascular occlusion and the control group. Results Overall, lactate and cholesterol remained elevated after 15 minutes of recovery and blood glucose and blood pressure did not vary among the groups. Conclusion Vascular occlusion training is an effective method for manipulating hemodynamic variables. Evidence level II; Clinical study.

Foram desenvolvidos vários métodos de treinamento de força, entre eles, a oclusão vascular. Porém, existem poucos estudos com grandes grupamentos musculares, devido à pouca adesão ao estilo de treino e ao fato de a oclusão vascular de grandes grupos musculares ser mais difícil. Objetivo Verificar e comparar os efeitos hemodinâmicos do exercício com e sem oclusão vascular em diferentes grupamentos musculares. Métodos Estudo quantitativo, cruzado, com procedimentos transversais e de campo. A amostra foi composta por 10 indivíduos saudáveis e fisicamente ativos do sexo masculino e feminino, na faixa etária de 18 a 30 anos. Com o desenho cruzado, todos os voluntários participaram de 3 grupos: intervenção com oclusão vascular, intervenção sem oclusão vascular e grupo controle. Resultados De forma geral, entre grupos, o lactato e o colesterol se mantiveram elevados depois de 15 minutos de recuperação, a glicemia e as pressões arteriais não variaram. Conclusão O treinamento com oclusão vascular é um método eficaz para manipular as variáveis hemodinâmicas. Nível de evidência II; Estudo clínico.

ABSTRACT

Objective@#The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.@*Methods@#The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.@*Results@#A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).@*Conclusion@#An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

ABSTRACT

SUMMARY: The aim of this study is to investigate the effects of Protocatechuic acid and Corchorus olitorius on streptozotocin (STZ) induced diabetic rat testis tissue. Randomly selected Wistar Albino rats were divided into five groups as; Diabetes Mellitus, Diabetes Mellitus treated with Corchorus Olitorus (STZ+CO), Diabetes Mellitus treated with Protacatechuic acid (STZ+PCA), Corchorus olitorius (CO), Protocatechuic acid (PCA) and Control. Diabetic model was generated by intraperitoneal injection of 60 mg/kg Streptozotosin. After 48 hours of the STZ injection, blood samples were collected from tail vein in order to measure blood glycose levels. Over 250 mg/dL accepted as diabetic subjets and fed with 250 mg/kg Corchorus olitorius or 20 mg/kg PCA by oral gavage for three weeks. At the end of the experiment, right testes were removed and fixed in 10 % neutral formaldehyde for paraffine embedding. Sections were stained by HE, Masson trichrome, PAS and TUNEL for microscopic evaluation. Control, PCA-only and Corchorus olitorius-only treated group testes tissues showed a normal tissue organization, when degeneration in seminiferous tubules, the vacuolization, seperations in spermatogenic cell series, outpouring of cell groups in the lumen, vesicular body formation, liquid accumulation in the interstitial region and edema were observed in STZ induced diabetic models and untreated groups. Besides, higher amount of TUNEL (+) stained cells were determined in STZ group. On the other hand, blood glucose level and number of TUNEL (+) stained cells were decreased as a result of PCA and Corchorus olitorius treatment. Because of the reduction of blood glucose level and apoptotic cell numbers, PCA and Corchorus olitorius decreace the complications of diabetes mellitus induced rat testis.


RESUMEN: El objetivo de este estudio fue investigar los efectos del ácido protocatéquico y Corchorus olitorius sobre el tejido testicular de rata diabética inducida por estreptozotocina (STZ). Las ratas Wistar Albino fueron seleccionadas al azar y se dividieron en cinco grupos; Diabetes Mellitus, Diabetes Mellitus tratada con Corchorus olitorius (STZ + CO), Diabetes Mellitus tratada con ácido protocatéquico (STZ + PCA), Corchorus olitorius (CO), ácido protocatéquico (PCA) y Control. El modelo diabético se generó por inyección intraperitoneal de 60 mg/kg de estreptozotosina. Después de 48 horas de la inyección de STZ, se recogieron muestras de sangre de la vena de la cola para medir los niveles de glucosa. Niveles mayores a 250 mg/dL fueron considerados como especímenes diabéticos y alimentados con Corchorus olitorius de 250 mg/kg o PCA de 20 mg/kg por sonda oral durante tres semanas. Al final del experimento, se extirparon los testículos derechos y se fijaron en formaldehído neutro al 10 % para la inclusión en parafina. Las secciones se tiñeron con HE, tricromo de Masson, PAS y TUNEL para evaluación microscópica. Los tejidos de los testículos de los grupos control, tratados solo con PCA y con Corchorus olitorius mostraron una organización tisular normal. En cambio en modelos diabéticos inducidos por STZ y grupos no tratados se observó degeneración en los túbulos seminíferos, vacuolización, separaciones en series de células espermatogénicas, efusión de grupos celulares en la luz, formación del cuerpo vesicular, acumulación de líquido en la región intersticial y edema. Además, se determinó una mayor cantidad de células teñidas con TUNEL (+) en el grupo STZ. Por otro lado, el nivel de glucosa en sangre y el número de células teñidas con TUNEL (+) disminuyeron como resultado del tratamiento con PCA y Corchorus olitorius. Debido a la reducción del nivel de glucosa en sangre y el número de células apoptóticas, se observó que PCA y Corchorus olitorius disminuyen las complicaciones de los testículos de rata inducidos por diabetes mellitus.

ABSTRACT

Este estudo teve por objetivo avaliar o desenvolvimento ponderal e a dinâmica dos parâmetros hematológicos e bioquímicos de cordeiros Pantaneiros submetidos a diferentes manejos de amamentação dos 15 aos 43 dias. Foram separados 30 cordeiros em três diferentes grupos (n=10). Os grupos foram caracterizados conforme o tempo de permanência das ovelhas com suas crias em diferentes sistemas de amamentação: MAM24 - ovelhas e cordeiros 24 horas em conjunto; MAM12 - ovelhas e cordeiros 12 horas em conjunto durante a noite; MAM2x30 - ovelhas e cordeiros 30 minutos de manhã e 30 minutos à tarde em conjunto. As coletas de amostras sanguíneas e as pesagens ocorriam a cada sete dias. Houve aumento significativo no peso com o avanço da idade dos cordeiros nos três manejos, mas os tratamentos não diferiram entre si para o ganho de peso. Houve diferenças entre os três tratamentos para a variável hematológica CHGM e para as variáveis bioquímicas AST, glicose, ureia e proteína total. As variáveis bioquímicas foram influenciadas pela faixa etária dos animais. Os diferentes manejos de amamentação não influenciaram o desenvolvimento ponderal dos cordeiros. Não ocorreram alterações patológicas. Alguns parâmetros hematológicos e bioquímicos podem ser influenciados pelo desenvolvimento etário dos cordeiros.(AU)

The groups were characterized according to the length of stay of ewes with their young in different breastfeeding systems: MAM24 - ewes and lambs 24 hours together. MAM12- Sheep and lambs 12 hours together at night. MAM2x30 - sheep and lambs 30 minutes in the morning and 30 minutes in the afternoon together. Blood samples were collected and weighed every seven days. Significant increase in weight was observed with the age of the lambs in the three managements, but the treatments did not differ for weight gain. Differences were identified between the three treatments for the hematological variable CHGM and for the biochemical variables AST, glucose, urea and total protein. Correlating the age of the lambs with the biochemical variables, there was variation influenced by the age of the animals. The different management of breastfeeding did not influence the weight development of the lambs. Hematological and biochemical variations did not represent pathological changes. Some hematological and biochemical parameters may be influenced by the age development of lambs.(AU)

ABSTRACT

Diabetes Mellitus (DM) is a condition marked by hyperglycaemia that causes systemic complications, including urinary vesicle dysfunction due to oxidative stress. Further, antioxidants, as well as alpha lipoic acid (ALA), may be a response to this pathological condition. The present study verified the action of ALA as a supplement in ration on glycemia and urinary vesicle structures of rats induced by streptozotocin. The rats were divided into 4 groups: Control (CG), Alpha Lipoic (ALAG), Diabetic control (DCG), and the Diabetic alpha lipoic (DALAG) group. For induction, the diabetic groups were initially induced with streptozotocin (dose 60 mg/kg). Subsequently, group glycemia was evaluated weekly. After 8 weeks, the rats were euthanized and the bladder was collected. The bladders were histologically processed and the slides were stained with Masson's Trichrome for the histomorphometry of epithelial height, connective and muscular tissue and coloration of PicroSirius Red for further analysis of collagen fibers of the bladder. The data of the glycemia demonstrated an inferior median in DALAG compared to DGC (p<0.01). The epithelial height and percentage of the muscle tissue were greater in DALAG compared to the DGC, but not significant. However, GDAL showed improvement in the organization of collagen fibers. In conclusion, bladder the morphology alterations caused by DM were not alleviated by the administration of ALA in 8 weeks of the experiments.


La diabetes mellitus (DM) es una afección marcada por hiperglucemia que causa complicaciones sistémicas, incluida la disfunción de la vejiga urinaria debido al estrés oxidativo. Además, los antioxidantes, así como el ácido alfa lipoico (ALA), pueden ser una respuesta a esta condición patológica. El presente estudio verificó la acción de ALA como suplemento en la ración sobre la glucemia y las estructuras de la vejiga urinaria de ratas inducidas por estreptozotocina. Las ratas se dividieron en 4 grupos: control (CG), alfa lipoico (ALAG), control diabético (DCG) y el grupo diabético alfa lipoico (DALAG). Para la inducción, los grupos diabéticos se aplicó estreptozotocina (dosis 60 mg/kg). Posteriormente, la glucemia grupal se evaluó semanalmente. Después de 8 semanas, las ratas se sacrificaron y se retiró la vejiga urinaria. Las vejigas se procesaron histológicamente y las muestras se tiñeron con tricromo de Masson para la histomorfometría y así evaluar la altura epitelial, el tejido conectivo y muscular. Además se tiñeron cond PicroSirius Red para un análisis posterior de las fibras colágenas de la vejiga urinaria. Los datos de la glucemia demostraron una mediana inferior en DALAG en comparación con DGC (p <0,01). La altura epitelial y el porcentaje de tejido muscular fueron mayores en DALAG en comparación con el DGC, pero no estadísticamente significativos. Sin embargo, GDAL mostró una mejora en la organización de las fibras de colágeno. En conclusión, la morfología de las alteraciones de la vejiga causada por DM no se alivió con la administración de ALA en 8 semanas de estudio.

ABSTRACT

SUMMARY: The objective of this study was to describe the effects of monosodium glutamate on the collagen of the parotid gland in an obesity model. 18 newborn male Sprague Dawley rats were used (first control group; second group of MSG1: 4 mg/g of monosodium glutamate weight, 5 doses, and third group of MSG2: 4 mg/g of monosodium glutamate, 5 doses, maintained for 8 and 16 weeks respectively). The content and type of collagen were analyzed, in addition to the levels of cholesterol, glucose, triglycerides and uric acid. Monosodium glutamate produced an increase in the obesity rates of the MSG2 group, in addition to an increase in blood cholesterol, glucose and uric acid levels compared to the control group. Type III collagen in the MSG2 group showed a statistically significant increase. Monosodium glutamate induced obesity, in addition to an increase in type III collagen fibers.

ABSTRACT

A acupuntura se caracteriza pela estimulação de pontos cutâneos específicos por meio do uso de agulhas. A auriculoterapia consiste na estimulação mecânica de pontos específicos do pavilhão auricular com esferas de aço, ouro, prata, plástico, agulhas ou sementes de mostarda. A acupuntura é recomendada para promoção, manutenção e recuperação da saúde, bem como prevenção de agravos e doenças. Além disso, parece propiciar a liberação de neurotransmissores e outras substâncias responsáveis pela promoção da analgesia. A auriculoterapia promove a regulação psíquico-orgânica do indivíduo. Ambas as práticas foram incorporadas no SUS mediante Portaria nº 971, de 03 de maio de 2006. Qual é a eficácia/efetividade e a segurança da acupuntura e da auriculoterapia para o tratamento de diabete melito tipo 2 (DM2) em adultos e/ou idosos? As buscas foram realizadas em cinco bases de dados sem restrição de ano de publicação. Foram incluídas revisões sistemáticas em inglês, português e espanhol que avaliaram os efeitos de ambas as tecnologias no tratamento da diabete melito tipo 2 na população adulta e idosa. A avaliação da qualidade metodológica foi realizada por meio do AMSTAR 2, feita por uma pesquisadora e revisada por outra. Nesta revisão rápida, produzida em cinco dias, foram utilizados atalhos metodológicos, de maneira que apenas o processo de seleção foi realizado em duplicidade e de forma independente. Resultados Dos 66 relatos encontrados nas bases, foi incluída uma revisão sistemática com metanálise que atendeu aos critérios de elegibilidade. A avaliação da qualidade indica que a revisão é de baixa qualidade metodológica. A revisão apresentou resultados sobre o uso de acupuntura e auriculoterapia no controle glicêmico de pessoas com DM2. Houve pouca informação sobre a segurança da prática de acupuntura e nenhuma sobre auriculoterapia. A prática de acupuntura, da eletroacupuntura e auriculoterapia combinadas com cuidado usual mostraram efeito no controle da glicemia de jejum, glicemia duas horas depois de um teste de tolerância à glicose e hemoglobina glicosilada. Somente em relação a prática de acupressão que houve resultados sem significância estatística. A revisão sistemática abordou o uso da auriculoterapia, observando resultados benéficos no controle glicêmico. Foram encontradas poucas informações sobre eventos adversos para avaliar essas práticas são seguras. Embora os resultados sejam favoráveis à acupuntura, eles são baseados em uma única revisão sistemática que analisou estudos primários com alto risco de viés. A própria revisão foi avaliada como de baixa qualidade metodológica, por isso as evidências devem ser vistas com cautela. Além disso, a heterogeneidade dos resultados estatísticos é elevada e faltam informações sobre o tempo de acompanhamento dos participantes dos ensaios. Os relatos sobre eventos adversos são escassos e não permitem tecer considerações sobre a segurança do uso dessas tecnologias em pacientes diabéticos

ABSTRACT

Gastric emptying and plasma glucose were evaluated in young and adult dogs, fed with dry and wet food, submitted to different periods of pre-anesthetic fasting (6, 8, and 12 hours). Forty healthy dogs were selected, which were segmented into four groups according to the age group and type of diet. It was evaluated the gastric emptying by ultrasound and serum glycemia. Only 17.5% presented complete gastric emptying, and no significant differences were found between the 6 and 8-hour fasting evaluations, or between the age groups and the diets, considering significance level p<0.05. Mean plasma glucose values from the groups indicated normal glycemia at all times of evaluation. A significant difference was found between the means of glycemia in young and adult dogs, with the 8-hour fasting with wet diet (p=0.03) and with 12 hours with dry diet (p=0.04). Healthy young and adult dogs, in physiological equilibrium, maintain average values of plasma glucose despite prolonged periods of pre-anesthetic fasting, which may be necessary, since 8-hour fasting for solid food is not enough to provide complete gastric emptying.(AU)


Avaliou-se o esvaziamento gástrico e a glicemia plasmática em cães jovens e adultos, alimentados com ração seca e úmida, submetidos a diferentes períodos de jejum pré-anestésico (6, 8 e 12 horas). Foram selecionados 40 cães hígidos, os quais foram segmentados em 4 grupos de acordo com a faixa etária e o tipo de dieta administrada. Foi avaliado o esvaziamento gástrico por ultrassonografia e a glicemia sérica. Apenas 17,5% apresentaram completo esvaziamento gástrico, não sendo encontradas diferenças significativas entre as avaliações com 6 e 8 horas de jejum, ou entre as faixas etárias e dietas, considerando nível de significância p<0,05. Os valores médios da glicose plasmática dos grupos indicaram normoglicemia em todos os momentos de avaliação. Foi encontrada diferença significativa entre as médias da glicemia dos cães jovens e adultos, no período de 8 horas de jejum com dieta úmida (p=0,03) e com 12 horas nos animais com dieta seca (p=0,04). Conclui-se que cães hígidos jovens e adultos, em equilíbrio fisiológico, mantêm valores normais de glicemia plasmática apesar de períodos prolongados de jejum pré-anestésico, os quais podem ser necessários, tendo em vista que 8 horas de jejum alimentar de sólidos não é suficiente para proporcionar completo esvaziamento gástrico.(AU)

ABSTRACT

Resumo O presente estudo investigou a associação entre o consumo de bebidas açucaradas e variáveis antropométricas e bioquímicas em análise transversal, realizado com dados secundários referentes à primeira consulta do ensaio clínico randomizado Dieta Cardioprotetora Brasileira (2013-2014). Foram coletados peso, altura, circunferência da cintura, perfil lipídico e glicemia de jejum e dados de um recordatório alimentar de 24 horas. Diferenças entre o consumo e não consumo de bebidas açucaradas foram avaliadas pelo teste T de student. Para analisar a associação entre o consumo de bebidas açucaradas e fatores bioquímicos e antropométricos foi utilizado o teste qui quadrado. A amostra foi de 2.172 indivíduos, sendo a maioria homens (58,5%), idosos (63,6%), do nível econômico C (57,3%), com ensino fundamental (45,8%) e com excesso de peso (62,7%). Houve associação significativa entre o consumo de bebidas açucaradas e maior valores de índice de massa corporal (p=0,029), circunferência da cintura (p=0,004) e triglicerídeos (p=0,023). Esses resultados reforçam a necessidade de intervenção nutricional quanto ao consumo de bebidas açucaradas como parte do tratamento dietético desta população.


Abstract This study investigated the association between consumption of sugar-sweetened beverages and anthropometric and biochemical variables in a cross-sectional study conducted with secondary data from the first visit of the randomized clinical trial of the Brazilian Cardioprotective Nutritional Program (BALANCE Program) (2013-2014). Weight, height, waist circumference, lipid profile and fasting glycemia and a 24-hour diet recall were collected. Differences between consumption and non-consumption of sugar-sweetened beverages were evaluated by Student's t-test. The Chi-square test was employed to analyze the association between consumption and non-consumption of sugar-sweetened beverages and biochemical and anthropometric factors. The sample consisted of 2,172 individuals, mostly men (58.5%), elderly (63.6%), C-rated economic class (57.3%), and overweight (62.7%). A statistically significant difference was found between the consumption of sugar-sweetened beverages and higher BMI values (p=0.029), waist circumference (p=0.004) and triglycerides (p=0.023). These results emphasize the need for nutritional intervention regarding the consumption of sugar-sweetened beverages as part of the dietary treatment of this population.

ABSTRACT

Abstract Objective To investigate the effects of intro-oral injection of parathyroid hormone (PTH) on tooth extraction wound healing in hyperglycemic rats. Methodology 60 male Sprague-Dawley rats were randomly divided into the normal group (n=30) and DM group (n=30). Type 1 diabetes mellitus (DM) was induced by streptozotocin. After extracting the left first molar of all rats, each group was further divided into 3 subgroups (n=10 per subgroup), receiving the administration of intermittent PTH, continuous PTH and saline (control), respectively. The intermittent-PTH group received intra-oral injection of PTH three times per week for two weeks. A thermosensitive controlled-release hydrogel was synthesized for continuous-PTH administration. The serum chemistry was determined to evaluate the systemic condition. All animals were sacrificed after 14 days. Micro-computed tomography (Micro-CT) and histological analyses were used to evaluate the healing of extraction sockets. Results The level of serum glucose in the DM groups was significantly higher than that in the non-DM groups (p<0.05); the level of serum calcium was similar in all groups (p>0.05). Micro-CT analysis showed that the DM group had a significantly lower alveolar bone trabecular number (Tb.N) and higher trabecular separation (Tb.Sp) than the normal group (p<0.05). The histological analyses showed that no significant difference in the amount of new bone (hard tissue) formation was found between the PTH and non-PTH groups (p>0.05). Conclusions Bone formation in the extraction socket of the type 1 diabetic rats was reduced. PTH did not improve the healing of hard and soft tissues. The different PTH administration regimes (continuous vs. intermittent) had similar effect on tissue healing. These results demonstrated that the metabolic characteristics of the hyperglycemic rats produced a condition that was unable to respond to PTH treatment.

ABSTRACT

Introdução: Evidências têm mostrado uma associação entre anemia e Diabetes Mellitus. Contudo, a relação entre anemia e Diabetes Mellitus Gestacional (DMG) ainda não está bem estabelecida, bem como sua repercussão na instabilidade genômica. Portanto, objetivou-se verificar a associação entre anemia e instabilidade genômica em mulheres com DMG atendidas em um hospital universitário. Métodos: Estudo transversal com mulheres apresentando diagnóstico de DMG que realizaram pré-natal no Hospital Universitário de Santa Maria (RS). Informações referentes ao DMG, anemia e suplementação de ferro foram obtidas nos prontuários. A instabilidade genômica foi avaliada pelo ensaio de citoma em micronúcleos em células bucais (BMCyt). Resultados: Das 44 gestantes avaliadas, 28,6% apresentaram anemia e 79,5% foram suplementadas com ferro. Das gestantes que realizaram suplementação, 75,0% não apresentaram anemia gestacional. Níveis de hemoglobina não se associaram com a instabilidade genomica (p > 0,05), mas foi observada uma associação entre brotos nucleares e os níveis de glicemia (r = 0,977; p = 0,003). Conclusão: Não foi verificado associação entre anemia e instabilidade genômica em mulheres com DMG.(AU)


Introduction: There is evidence of an association between anemia and diabetes mellitus. However, the relationship between anemia and gestational diabetes mellitus (GDM) remains to be established, as well as its impact on genomic instability. Therefore, we aimed to examine the association between anemia and genomic instability in women with GDM treated at a university hospital. Methods: A cross-sectional study of women with a diagnosis of GDM who received prenatal care at the University Hospital of Santa Maria, southern Brazil. Data on GDM, anemia, and iron supplementation were obtained from medical records. Genomic instability was assessed by the buccal micronucleus cytome (BMCyt) assay. Results: Of 44 pregnant women evaluated, 28.6% had anemia and 79.5% received iron supplementation; of the latter, 75.0% did not have gestational anemia. Hemoglobin levels were not associated with genomic instability (p > 0.05), but an association was found between nuclear buds and blood glucose levels (r = 0.977; p = 0.003). Conclusion: There was no association between anemia and genomic instability in women with GDM.(AU)

ABSTRACT

Abstract This study aimed to investigate the effects of chronic restraint stress (RS) and a high-fat diet (HFD) on the osseointegration of titanium implants in a rat model. After the surgical insertion of titanium implants into the metaphysis of the tibial bone, the rats were randomly divided into four equal groups (n = 8 each): control (CNT), restraint stress (RS), high-fat diet (HFD), and restraint stress plus high fat diet (RS-HFD). CNT: Rats received no further treatment during the 92-day experimental period. RS: Stress was applied to the rats beginning from two days after the implant surgery for one hour per day for the first 30 days, two hours per day for the next 30 days, and three hours per day for the last 30 days. HFD: Rats were fed a HFD for the following 90 days starting two days after surgery. RS-HFD: Rats were fed a HFD and RS was applied to rats for the following 90 days, starting two days after surgery. At the end of the experimental period, the rats were euthanized, and the implants and surrounding bone tissues were removed for histological analysis. Statistical analysis was performed by one way ANOVA and Bonferrroni tests. There were no significant differences in the bone-implant connection levels between the groups (p > 0.05), but in the HFD and RS-HFD groups, the bone filling ratios were found to be lower compared with the controls (p < 0.05) The data analyzed in this study suggest that an HFD with or without chronic RS adversely affected bone tissue in the rats during the 90-day osseointegration period.
