Survival of commercial probiotic strains and their effect on dark chocolate synbiotic snack with raspberry content during the storage and after simulated digestion

BACKGROUND: A key challenge for manufacturers of pro-health food containing active probiotic microorganisms is to develop a product with attractive sensory features along with maintenance of declared number of microorganisms during storage and transfer by alimentary tract. RESULTS: The highest concentration of polyphenols was observed in snacks without an additive of probiotics as well as those with an additive of L. rhamnosus and B. animalis bacteria and concentration of these compounds increased by 9.5% during six months of storage. None of the products distinguished itself in the sensorial assessment although each was assessed positively. The number of microorganisms was stable and comparatively high during six months of storage at a room temperature and in cooling conditions (108 cfu/g). In the digestion model, an influence of aggressive digestion conditions was examined in the alimentary tract on the number of microorganisms, which allowed to arrange strains from the most resistant (S. boulardii) to the most sensitive (B. breve). It must be noted that currently on the market there is no available snack containing probiotic yeast as well as there is no literature data on works on such formulation of food. CONCLUSIONS: In the newly developed snack made of chocolate, in which sugar has been replaced with maltitol, a raw material was added in the form of raspberry, prebiotic in the form of inulin and a strain of probiotic bacteria, including the unprecedented so far S. boulardii, which stands a high chance to occupy a good place on the market of functional food.

Spray Drying of Coloring Extracts Produced by Fungi Isolated from Brazilian Caves

Abstract Pigments produced by submerged fermentation of three filamentous fungi isolated from Brazilian caves, namely Aspergillus keveii, Penicillium flavigenum, and Epicoccum nigrum, were submitted to spray drying in presence of the adjuvants maltodextrin, modified starch or gum arabic. Yellow fine powders with low moisture content and water activity, and high color retention (> 70%) were successfully generated with a high product recovery ratio (> 50%), independently of the adjuvant used. The dried products have enhanced stability and potential to might be used as a natural colorant in food and pharmaceutical applications.

Effect of ferric carboxymaltose in the management of postpartum iron deficiency anemia

Background: Iron deficiency is the most common cause of anemia, around the world, with postpartum hemorrhage one of the reasons. Different treatment options are available for correction of iron deficiency, ferric carboxymaltose being the most recent

Objective: To determine the effectiveness of ferric carboxymaltose in the management of iron deficiency anemia in the postpartum period

Methodology: An experimental study was conducted at Sheikh Zayed Medical College/Hospital Rahim Yar Khan. 30 female patients, with documented iron deficiency anemia within 10 days of post partum period and with no history of renal or hepatic disease, infection, anemia due to any other causes, severe anemia requiring blood transfusion and no parenteral iron therapy in last 20 days, were included in the study. All the patient were given ferric carboxymaltose 15mg/kg body weight [max 1000mg] intravenous infusion. Pre and post therapy complete blood picture including hemoglobin and serum ferritin levels were compared after 1 week. The data was entered and analyzed in SPSS version15

Results: Significant increase in both hemoglobin and serum ferritin levels was noted in patients with mean rise being 2.4g/dl and 338.3 ng/ml in hemoglobin and serum ferritin levels, respectively. Mild rash and fever were the only adverse events noted, in only one patient, each

Conclusion: Ferric carboxymaltose appears to be a very effective drug for the treatment of iron deficiency anemia both in terms of rise in hematological indices and low adverse event profile

TREATMENT OF ANEMIA AND IMPROVEMENT OF QUALITY OF LIFE AMONG PATIENTS WITH CROHN'S DISEASE: experience using ferric carboxymaltose

Objectives - Anemia is the most common hematological alteration in patients with Crohn's disease, and is frequently related to intestinal inflammatory activity. Its cause is multifactorial and mostly associated with absolute iron deficiency (iron deficiency anemia) and/or functional iron deficiency (inflammation anemia or anemia of chronic disease). It may also be identified through other causes, such as folic acid or vitamin B12 deficiency and secondary to adverse effects from medications (salicylic derivatives and immunosuppressive drugs). In the present study, patients with active Crohn's disease and anemia were evaluated and treated with intravenous ferric carboxymaltose. We discuss the therapeutic schemes (doses), safety, results and improvement of quality of life. Methods - In the present prospective study, 10 consecutive patients with Crohn's disease, with moderate to severe activity, with anemia (Hb: 6.7 to 10 g/dL), who were attended between March 2014 and March 2015, were evaluated. Six (60%) were men and four were women, all with moderate or severe anemia (hemoglobin <10 g/dL). They were treated with a maximum of three intravenous infusions of 1000 mg of ferric carboxymaltose, of at least 15 minutes in duration. It was also sought to correlate the inflammatory Crohn's disease activity degree (measured using the Crohn's Disease Activity Index, CDAI) and C-reactive protein level with the severity of anemia. The primary outcome was an increase in Hb of ≥2 g/dL and the secondary outcome was the normalization of anemia (Hb ≥12 g/dL for women and ≥13 g/dL for men) and the improvement in quality of life seen 12 weeks after the last application of carboxymaltose. Results - Among the 10 patients studied, parenteral iron supplementation was administered in three cases during hospitalization and the others received this on an outpatient basis. The total iron dose ranged from 1,000 to 2,000 mg, with an average of 1,650 mg. Crohn's disease activity measured using CDAI and C-reactive protein correlated with the intensity of anemia. An increase of 2 g/dL occurred in eight (80%) patients after 12 weeks and normalization of anemia was found in seven (70%) patients. Improvements in quality-of-life scores were found for all (100%) patients after 12 weeks. Carboxymaltose was well tolerated. Three patients presented adverse reactions (two with nausea and one with headache) of mild intensity. Conclusions - Anemia is a frequent complication for Crohn's disease patients. Intravenous iron therapy has been recommended for Crohn's disease patients, because for these patients, oral iron absorption is very limited. This is because of the inflammatory state and "blocking" of iron entry into enterocytes through hepcidin action on ferroportin, along with the elevated rates of gastrointestinal adverse events that compromise adherence to treatment and possibly aggravate the intestinal inflammatory state. The degree of Crohn's disease activity, as measured using CDAI and C-reactive protein, correlates with the severity of anemia. Carboxymaltose is a safe drug, which can be administrated in high doses (up to 1,000 mg per application per week) and corrects anemia and iron stocks over a short period of time, with consequent improvement in quality of life.

Objetivos - Anemia é a alteração hematológica mais comum em portadores de doença de Crohn, estando frequentemente relacionada à atividade inflamatória intestinal. Sua causa é multifatorial, está associada na maioria das vezes com deficiência absoluta de ferro (anemia ferropriva) e/ou deficiência funcional de ferro (anemia da inflamação ou anemia de doença crônica), podendo também ser identificada outras causas como deficiência de ácido fólico ou vitamina B12 e secundária a efeitos adversos de medicamentos (derivados salicílicos e imunossupressores). Neste trabalho, avaliamos portadores de doença de Crohn em atividade com anemia que foram tratados com carboximaltose férrica endovenosa, e discutimos os esquemas terapêuticos (doses), a segurança e os resultados, assim como a melhora da qualidade de vida. Métodos - Neste estudo prospectivo, avaliamos 10 consecutivos pacientes portadores de doença de Crohn de moderada a grave atividade com anemia (Hb: 6,7 a 10 g/dL) que foram atendidos no período de março de 2014 a março de 2015. Eram seis (60%) do sexo masculino e quatro do sexo feminino, todos com anemia moderada ou grave (hemoglobina <10g/dL), tratados com no máximo três infusões de 1000 mg de carboximaltose férrica por via endovenosa em, pelo menos, 15 minutos. Procurou-se também correlacionar o grau de atividade inflamatória da doença de Crohn (mensuração realizada com o IADC-índice de atividade da doença de Crohn) e dosagem da proteína C reativa com a gravidade da anemia. O desfecho primário foi aumento da Hb de ≥2 g/dL e desfecho secundário a normalização da anemia (Hb ≥12 g/dL para mulheres e ≥13 g/dL para homens) e melhora na qualidade de vida após 12 semanas da aplicação da última dose de carboximaltose férrica. Resultados - Dos 10 pacientes estudados, em 3 a suplementação parenteral de ferro foi realizada durante internação hospitalar, o restante em regime ambulatorial. A dose total de ferro administrada variou de 1.000 a 2.000 mg, sendo a média de 1.650 mg. A atividade da doença de Crohn mensurada pelo IADC e pelo PCR se correlacionou com a intensidade da anemia. O aumento de 2 g/dL ocorreu em oito (80%) pacientes após 12 semanas e a normalização da anemia foi observada em sete (70%). Melhora do escore de qualidade de vida foi observada em todos (100%) após 12 semanas. A carboximaltose férrica foi bem tolerada, três pacientes apresentaram reações adversas (2 - náusea e 1 - cefaléia) de leve intensidade. Conclusões - Anemia é uma complicação frequente em portadores de doença de Crohn. A terapia com ferro por via endovenosa tem sido a recomendada em portadores de doença de Crohn, pois nestes pacientes a absorção do ferro oral é bastante limitada devido ao estado inflamatório e "bloqueio" da entrada de ferro nos enterócitos por ação da hepcidina sobre a ferroportina, além das elevadas taxas de eventos adversos gastrointestinais que comprometem a adesão ao tratamento e podem agravar o estado inflamatório intestinal. O grau de atividade da doença de Crohn mensurado pelo IADC e PCR se correlaciona com a severidade da anemia. A carboximaltose férrica é uma droga segura, pode ser administrada em altas doses (até 1.000 mg por aplicação por semana), corrige a anemia e os estoques de ferro em curto espaço de tempo, com consequente melhora da qualidade de vida.

Efficacy of Ferric Carboxymaltose in Anaemia of Malignancy - A Pilot Study.

Anaemia is an important problem in malignancy. It may be due to chronic causes like malnutrition, marrow infiltration, associated renal or endocrine disorders and it may be complicated with blood loss. Measures like blood transfusion, erythropoietin injections often pose a logistical problem. Parenteral iron injections have proved to be useful in fighting anaemia in some chronic conditions e.g. patients on hemodialysis. Aims and Objectives: Primarily to see the observable change in hemoglobin (Hb) level with ferric carboxymaltose (FCM) in treating patients of malignancy on anti-cancer treatment. Materials and Methods: Twenty seven patients were enrolled for this study who were suffering from various malignancies. The baseline Hb level was estimated and FCM injection was administered as per the schedule of 500 mg intravenously (IV) weekly once. The overall results of increase in Hb level was noted during the middle of the treatment (chemotherapy or radiotherapy) and later 3-4 weeks after treatment completion. The results were analysed using SPSS and the mean values of initial Hb and after treatment were analysed. Level of significance (p value) was noted using t test. Results: In 27 patients the mean initial Hb level was 8.09 g/dl before treatment which increased to 10.28 g/dl after FCM treatment (p <0.0001). Conclusion: Treatment with FCM definitely led to a significant increase in Hb level in patients of malignancy undergoing treatment. However, further detailed study is needed to establish its definite role in improving the body iron parameters.

The use of (alfa)a-methyl-D-glucoside, a synthetic analogue of maltose, as inducer of amylase by Aspergillus sp in solid-state and submerged fermentations

The use of a methyl-D-glucoside (aMG), a synthetic analogue of maltose, as carbon source and inducer of amylase synthesis to several species of Aspergillus was studied in submerged and solid-state fermentations. Among a group of ten species, A. tamarii, A. fumigatus and A. flavus were able to produce biomass and high specific amylolytic activity in submerged cultures containing aMG as the only carbon source. In solid state fermentation, the enrichment of basal wheat bran or corn cob medium with aMG increased up to 3 times the production of amylases. In both submerged and solid state fermentations, aMG was more effective inducer of amylases than maltose and starch.(au)
