RESUMO

The impact of 15% dietary inclusion of Spirulina (Arthrospira platensis) in broiler chickens was explored, focusing on blood cellular components, systemic metabolites and hepatic lipid and mineral composition. From days 14 to 35 of age, 120 broiler chickens were divided and allocated into four dietary treatments: a standard corn and soybean meal-based diet (control), a 15% Spirulina diet, a 15% extruded Spirulina diet, and a 15% Spirulina diet super-dosed with an enzyme blend (0.20% porcine pancreatin plus 0.01% lysozyme). The haematological analysis revealed no significant deviations (p > 0.05) in blood cell counts across treatments, suggesting that high Spirulina inclusion maintains haematological balance. The systemic metabolic assessment indicated an enhanced antioxidant capacity in birds on Spirulina diets (p < 0.001), pointing toward a potential reduction in oxidative stress. However, the study noted a detrimental impact on growth performance metrics, such as final body weight and feed conversion ratio (both p < 0.001), in the Spirulina-fed treatments, with the super-dosed enzyme blend supplementation failing to alleviate these effects but with extrusion mitigating them. Regarding hepatic composition, birds on extruded Spirulina and enzyme-supplemented diets showed a notable increase in n-3 fatty acids (EPA, DPA, DHA) (p < 0.001), leading to an improved n-6/n-3 PUFA ratio (p < 0.001). Despite this positive shift, a reduction in total hepatic lipids (p = 0.003) was observed without a significant change in cholesterol levels. Our findings underscore the need for further exploration into the optimal inclusion levels, processing methods and potential enzymatic enhancements of Spirulina in broiler diets. Ultimately, this research aims to strike a balance between promoting health benefits and maintaining optimal growth performance in poultry nutrition.

RESUMO

Optic neuropathies, such as glaucoma, are some of the leading causes of irreversible blindness worldwide. There has been a lot of research for potential therapies that could attenuate and even reduce the impact of the pathological pathways that lead to the loss of retinal ganglion cells (RGCs). In recent years, vitamin B3 (nicotinamide) has gained some interest as a viable option for these neurodegenerative diseases due to its fundamental role in enhancing the mitochondria metabolism of the RGCs. This review focuses on elucidating the impact of vitamin B3 on retinal cells, especially when in a dysfunctional state like what happens in optic neuropathies, especially glaucoma. This review also summarizes the existing and future research on the clinical effects of vitamin B3 in these optic neuropathies, and determines appropriate recommendations regarding its dosing, efficacy, and eventual side effects.

RESUMO

INTRODUCTION: Adjuvant endocrine therapy induces bone loss and increases fracture risk in women with hormone-receptor positive, early-stage breast cancer (EBC). We aimed to update a previous position statement on the management of aromatase inhibitors (AIs) induced bone loss and now included premenopausal women. METHODS: We conducted a systematic literature search of the medical databases from January 2017 to May 2020 and assessed 144 new studies. RESULTS: Extended use of AIs beyond 5 years leads to persistent bone loss in breast cancer extended adjuvant trials and meta-analyses. In addition to bone mineral density (BMD), vertebral fracture assessment (VFA) and trabecular bone score (TBS) were shown to independently predict fracture risk in real life prospective studies. FRAX® tool does not seem to be reliable for assessing fracture risk in CTIBL. In premenopausal women, there is strong evidence that intravenous zoledronate prevents bone loss but weak conflicting evidence on reducing disease recurrence from independent randomised controlled trials (RCTs). In postmenopausal women, the strongest evidence for fracture prevention is for denosumab based on a well-powered RCT while there is strong evidence for bisphosphonates (BPs) to prevent and reduce CTIBL but no convincing data on fractures. Adjuvant denosumab has failed to show anticancer benefits in a large, well-designed RCT. DISCUSSION AND CONCLUSIONS: Extended use of AIs and persistent bone loss from recent data reinforce the need to evaluate fracture risk in EBC women initiated on AIs. Fracture risk should be assessed with clinical risk factors and BMD along with VFA, but FRAX is not adapted to CTIBL. Anti-resorptive therapy should be considered in those with a BMD T-score < -2.0 SD or with ≥ 2 clinical risk factors including a BMD T-score < -1.0 SD. In premenopausal women, intravenous zoledronate is the only drug reported to prevent bone loss and may have additional anticancer benefits. In postmenopausal women, either denosumab or BPs can be prescribed for fracture prevention with pertinent attention to the rebound phenomenon after stopping denosumab. Adjuvant BPs, in contrast to denosumab, have shown high level evidence for reducing breast cancer recurrence in high-risk post-MP women which should be taken into account when choosing between these two.

RESUMO

Objectives. Hungry bone syndrome (HBS) is a severe and underdiagnosed complication of parathyroidectomy in the treatment of primary hyperparathyroidism (PHP) and secondary hyper-parathyroidism to chronic kidney disease (SHP-CKD).Methods. A longitudinal study was conducted to compare the postoperative outcomes of patients who developed HBS in two different time frames: before and after implementing a protocol with an intensive electrolytic monitoring and an algorithm regarding electrolytic supplementation.Results. Overall, 77 parathyroidectomies were included. In PHP, a protocol implementation led to an increased admission of patients in the Intermediate Care Unit for intensive electrolytic monitoring (p<0.001) and an increased rate of oral calcium replacement during hospital stay (p=0.013) compared to pre-protocol era. In SHP-CKD, duration of intravenous calcium replacement was reduced (p=0.010). The prevalence of HBS (9.8% in PHP and 58.3% in SHP-CKD) was similar between the two periods, although its diagnosis had an increased trend in PHP since the protocol implementation. None of the diagnosis of HBS was established due to hypocalcemic symptoms in the post-protocol era (contrary to pre-protocol period, p=0.021). Both hypocalcemia length and duration of surgical ward hospitalization were reduced (p=0.047 and p=0.042, respectively).Conclusions. An improved assessment of hyperparathyroidism and a decrease in HBS severity were noted in the post-protocol era. We strongly recommend the implementation of a standardized protocol with an intensive phosphocalcium monitoring in the high-risk patients who undergo parathyroidectomy due to hyperparathyroidism as it improves the health care and management of HBS.

RESUMO

PURPOSE: Acetylcholinesterase (AChE) inhibitors are used to treat Alzheimer's patients because they enhance cholinergic neurotransmission. It is urgent to find new and efficient inhibitors from natural sources, highly bioavailable with low or no toxicity. The plant kingdom is extremely rich in a variety of compounds that are potent AChE inhibitors: flavonoids and other phenolic compounds have been recognized as promising Alzheimer's treatment agents. In this study, in vitro acetylcholinesterase inhibition, antioxidant activities, and total flavonoid and phenolic contents of ethanol-water extracts from Quercus suber cork and corkback were evaluated. METHODS: The acetylcholinesterase activity was determined by a colorimetric assay based on Ellman's methodology. The Folin-Ciocalteu colorimetric method was used for total phenolic content determination and the aluminium chloride method for the determination of total flavonoid content. Antioxidant activity assays were performed using the DPPH and FRAP assays. RESULTS: The acetylcholinesterase inhibitory activity from Q. suber cork and corkback ethanol-water extracts was as follows: 62% inhibition with corkback extracts over 0.5 mg/mL and around 49% inhibition in cork extracts over 1.0 mg/mL extracts' concentration. Regarding the DPPH radical scavenging activity, the concentrations of cork and corkback ethanol-water extracts required for 50% DPPH inhibition (IC50) were 3.2 µg/mL and 4.0-5.2 µg/mL. Corkback extracts are less effective than Trolox standard (3.2 µg/mL) but cork extracts showed the same free radical scavenging activity compared to Trolox. Cork and corkback extracts have antioxidant power of 750.9-775.4 mg TEAC/g extract and 1051.2-2052.4 mg TEAC/g extract, respectively, which are significantly higher than the ones obtained with Trolox: 19.6-21.0 mg TEAC/g extract (cork assays) and 57.4-66.3 mg TEAC/g extract (corkback assays). The amounts of total phenolic (TPC) and flavonoid (TFC) compounds were 8.7-32.3 mg GAE/g and 4.8-10.7 mg CE/g dry mass for cork and 5.4-5.7 mg GAE/g and 42.5 mg CE/g dry mass for corkback extracts, respectively, using catechin (CE) and GAE (gallic acid) as standards. CONCLUSION: These findings demonstrate the remarkable potential of these extracts as valuable source of antioxidants with interesting acetylcholinesterase inhibitory activity.

RESUMO

BACKGROUND: Glioblastomas (GBM) are one of the most aggressive tumor of the central nervous system with an average life expectancy of only 1-2 years after diagnosis, even with the use of advanced treatments with surgery, radiation, and chemotherapy. There are several anticancer drugs with alkylating properties that have been used in the therapy of malignant gliomas. Temozolomide (TMZ) is one of them, widely used even in combination with ionizing radiation. However, the main disadvantage of using these types of drugs in the treatment of GBM is the development of cancer drug resistance. Research of bioactive compounds with anticancer activity has been heavily explored. PURPOSE: This review focuses on a carotenoid and a phlorotannin present in seaweed, namely fucoxanthin and phloroglucinol, and their anticancer activity against glioblastoma. The combination of natural compounds with conventional drugs is also discussed. CONCLUSION: Several natural compounds existing in seaweeds, such as fucoxanthin and phoroglucinol, have shown cytotoxic activity in models in vitro and in vivo, acting through different molecular mechanisms, such as antioxidant, antiproliferative, DNA damage/DNA repair, proapoptotic, antiangiogenic and antimetastic. Within the scope of interactions with conventional drugs, there are evidences that some seaweed compounds could be used to potentiate the action of anticancer drugs. However, their effects and mechanisms of action, alone or in combination with anticancer drugs, namely TMZ, in glioblastoma cell, still few explored and require more attention due to the unquestionable high potential of these marine compounds.

RESUMO

False banana /Ensete ventricosum [Welw.] Cheesman/ is exploited as a food crop in Ethiopia where it represents an important staple food. The plant is harvested and large amounts of biomass residues are originated, mainly from the pseudo stem (i.e., fiber bundles obtained from the leaf sheaths after being scrapped to produce starchy food) and the inflorescence stalk. These materials were studied in relation to their summative chemical composition, composition of lignin, lipophilic and polar extracts. Moreover, their structural characteristics, in view of their valorization, were scrutinized. The analytical studies were performed with the aid of FTIR, GC/MS, Py-GC/MS and SEM. The fiber bundles are aggregates of mainly long and slender fibers with low ash, extractives and lignin contents (3.8%. 4.4% and 10.5% respectively) and high holocellulose and α-cellulose contents (87.5% and 59.6% respectively). The hemicelluloses in the fibers are mostly highly acetylated xylans and the lignin is of the H-type (H:G:S, 1:0.7:0.8). This lignin composition is in line with the FTIR peaks at 1670 cm-1 and 1250 cm-1.The inflorescence stalk has high ash content (12.3% in the main stalk and 24.6% in fines) with a major proportion of potassium, high extractives (25.9%), and low lignin and α-cellulose contents (5.8% and 17.9% respectively). The stalk includes numerous starch granules in the cellular structure with the predominant presence of parenchyma. The potential valorization routes for these materials are clearly different. The fiber bundles could be used as a fiber source for paper pulp production with the possibility of a prior hemicelluloses removal while the inflorescence stalk has nutritional value for food and fodder. Furthermore, it can also be used for sugar fermentation products.

RESUMO

The bark from Quercus faginea mature trees from two sites was chemically characterized for the first time. The barks showed the following composition: ash 14.6%, total extractives 13.2%, suberin 2.9% and lignin 28.2%. The polysaccharides were composed mainly of glucose and xylose (50.3% and 35.1% of all monosaccharides respectively) with 4.8% of uronic acids. The suberin composition was: ω-hydroxyacids 46.3% of total compounds, ɑ,ω-alkanoic diacids 22.3%, alkanoic acids 5.9%, alkanols 6.7% and aromatics 6.9% (ferulic acid 4.0%). Polar extracts (ethanol-water) had a high phenolic content of 630.3 mg of gallic acid equivalents (GAE)/g of extract, condensed tannins 220.7 mg of catechin equivalents (CE)/g extract, and flavonoids 207.7 mg CE/g of extract. The antioxidant activity was very high corresponding to 1567 mg Trolox equivalents/g of extract, and an IC50 of 2.63 µg extract/ml. The lipophilic extracts were constituted mainly by glycerol and its derivatives (12.3% of all compounds), alkanoic acids (27.8%), sterols (11.5%) and triterpenes (17.8%). In view of an integrated valorization, Quercus faginea barks are interesting sources of polar compounds including phenols and polyphenols with possible interesting bioactivities, while the sterols and triterpenes contained in the lipophilic extracts are also valuable bioactive compounds or chemical intermediates for specific high-value market niches, such as cosmetics, pharmaceuticals and biomedicine.

RESUMO

We report a case of a 46-year-old woman with a history of autoimmune atrophic gastritis and recurrent erythema nodosum (EN). Laboratory results showed iron-deficiency anaemia, positive antiparietal cell antibodies and marginal deficiency of vitamin B12. Although EN was refractory to general measures (rest and non-steroidal anti-inflammatory drugs) and corticosteroid therapy, it was successfully treated with vitamin B12 supplementation.

RESUMO

Heartwood and sapwood of Quercus faginea were evaluated in relation to summative chemical composition and non-polar and polar extracts composition, including an assessment of antioxidant properties (DPPH and FRAP). Twenty trees from two sites in Portugal were analysed. Heartwood had approximately two times more solvent extractible compounds than sapwood (on average 19.0% and 9.5%). The lipophilic extractible compounds were below 1%, and most of them were polar e.g. ethanol-soluble compounds corresponded to 65% of total extractives in heartwood and 43% in sapwood. Lignin content was similar in sapwood and heartwood (28.1% and 28.6% of extractive-free wood respectively) as well as the sugar composition. Site did not influence the chemical composition. The lipophilic extractible compounds from both sapwood and heartwood included mainly saturated fatty acids (23.0% and 36.9% respectively) and aromatic compounds were also abundant in sapwood (22.9%). The ethanol-water extractibles had a high content of phenolic substances (558.0 and 319.4 mg GAE/g extract, respectively of heartwood and sapwood). The polyphenolic composition was similar in heartwood and sapwood with higher content of ellagitannins (168.9 and 153.5 mg tannic acid/g of extract in sapwood and heartwood respectively) and very low content of condensed tannins. The antioxidant activity was very high with IC50 of 2.6 µg/ml and 3.3 µg/ml for sapwood and heartwood respectively, as compared to standard antioxidants (IC50 of 3.8 µg/ml for Trolox). The ferric reducing ability was 2.8 and 2.0 mMol Trolox equivalents/g extract of heartwood and sapwood respectively. The variability between trees was low and no differences between the two sites were found. Q. faginea showed a very good potential for cooperage and other applications for which a source of compounds with antioxidant properties is desirable.

RESUMO

INTRODUCTION: To evaluate the results of the abdominal aortic aneurism endovascular treatment (EVAR), percutaneously and with local anesthesia, according to the concept of one day surgery. MATERIAL AND METHODS: Unicentric, retrospective analysis of patients with aorto-iliac aneurysmal disease, consecutively treated by EVAR with percutaneous access trough the Preclose technique (pEVAR), according to the outpatient criteria, with one overnight stay in the hospital. The technical success, exclusion of the aneurysmal sac, endoleak, re-intervention and mortality were evaluated. RESULTS: Twenty consecutive patients (all male; mean age 74.65 years) were treated by EVAR with percutaneous access and local anesthesia, from which 95% (19) presented with abdominal aortic aneurysm and 5% (1) common iliac aneurysm. All implants were sucessfully performed, with an initial endoleak rate of 10% (2), determined by one type 1a endoleak successfully corrected intra-operatively and one type 2a endoleak diagnosed in the first imaging control, which sealed spontaneously on the second control. Initial technical success for percutaneous closure was 97.5%, with one case reported of femoral pseudo-aneurism, posteriorly treated by percutaneous thrombin injection. Median length of stay was one day [1-10], with a mean follow-up of 11.4 months [1-36]. Both the re-intervention and mortality rate are 0% for the selected period. CONCLUSION: Our one day surgery model for the outpatient treatment of abdominal aortic aneurysm by the pEVAR technique is innovative, safe and effective, as long as the selection criteria are respected.


Introdução: Avaliar os resultados do tratamento endovascular do aneurisma da aorta abdominal (EVAR) por via percutânea e anestesia local, segundo o conceito de one day surgery.Material e Métodos: Análise retrospetiva, unicêntrica dos doentes com doença aneurismática aorto-ilíaca, consecutivamente submetidos a tratamento endovascular do aneurisma da aorta abdominal por via percutânea (pEVAR) pela técnica de Preclose, seguindo critérios de ambulatorização com pernoita após o procedimento. O sucesso técnico, exclusão do saco aneurismático, endoleak, reintervenção e tempo de internamento foram avaliados.Resultados: Vinte doentes consecutivos (todos homens, idade média 74,65 anos) foram tratados por pEVAR e anestesia local, dos quais 95% (19) apresentavam aneurisma da aorta abdominal e 5% (1) aneurisma da artéria ilíaca comum. Todos os implantes foram realizados com sucesso, com uma taxa de endoleak inicial de 10% (2), à custa de um endoleak 1a corrigido intraoperatoriamente com sucesso, e um endoleak 2a diagnosticado na primeira angio-tomografia computorizada pós-operatória, que selou espontaneamente no controlo aos 6 meses. O sucesso técnico inicial do encerramento percutâneo foi de 97,5%, com um caso reportado de pseudo-aneurisma femoral, corrigido posteriormente por injeção percutânea de trombina. A mediana de internamento foi de 1 dia [1-10], com follow-up médio de 11,4 meses [1-36]. A reintervenção e mortalidade são de 0% no período descrito. Conclusão: O tratamento ambulatório do aneurisma da aorta abdominal por via endovascular com acesso percutâneo segundo o nosso modelo de one day surgery é inovador, seguro e eficaz, respeitando os critérios de seleção.

RESUMO

Remission is the key treatment goal in rheumatoid arthritis and should provide the optimal state for patients. Clinical remission criteria are based on composite scores of disease activity and are widely used in clinical practice and trials. With the use of biologic therapies and treat to target strategies, rates of clinical remission have significantly improved. Despite achieving this target, many patients demonstrate structural and functional deterioration. This raises the question regarding the validity of clinical criteria, although they have evolved significantly over the years. Imaging modalities such as ultrasound have been described as more accurate methods of assessing the remission state compared with clinical assessment alone. Furthermore, immuno-pathological assessments are gaining significant interest as this would enable assessment of disease activity at the primary site of pathology. Further research is required to develop accurate biomarkers of remission. We aimed to review the evolution of remission criteria in rheumatoid arthritis to date and to evaluate novel concepts in and the future of defining remission.

RESUMO

Obesity is characterised by low-grade inflammation, which increases the metabolic syndrome (MetS) and cardiovascular risks. The aim of the present study was to verify the role of multicomponent therapy in controlling the MetS, inflammation and carotid intima-media thickness (cIMT) in obese adolescents. The second aim was to investigate the relationships between adipokines, the MetS parameters and cIMT. A total of sixty-nine obese adolescents participated in the present study and completed 1 year of multicomponent therapy (a combination of strategies involving nutrition, psychology, physical exercise and clinical therapy), and were divided according to their MetS diagnosis as follows: MetS (n 19); non-MetS (n 50). Blood analyses of glucose, lipid and adipokine concentrations (adiponectin, leptin, plasminogen activator inhibitor 1 (PAI-1) and C-reactive protein) were collected. Insulin resistance was assessed using the homeostasis model assessment for insulin resistance, quantitative insulin sensitivity check index and homeostasis model assessment-adiponectin. cIMT and visceral and subcutaneous fat were estimated using ultrasonography. At baseline, the MetS group presented higher waist circumference, glucose and insulin levels, and systolic and median blood pressures compared with the non-MetS group. After therapy, both groups showed improvements in the anthropometric profile, body composition, insulin level, insulin resistance, insulin sensibility, TAG and VLDL-cholesterol, adiponectin, leptin and PAI-1 levels, blood pressure and cIMT. The prevalence of the MetS was reduced from 27·5 to 13·0 %. Metabolic syndrome patients showed resistance in the attenuation of total cholesterol and LDL-cholesterol (LDL-C) levels and leptin:adiponectin and adiponectin:leptin ratios. In the MetS group, the variation in the adiponectin:leptin ratio was correlated with variations in glucose, insulin sensibility, total cholesterol, LDL-c and systolic blood pressure. Additionally, the number of MetS parameters was correlated with the carotid measurement. Moreover, the variation in cIMT was correlated with the variations in insulin sensibility, total cholesterol and LDL-c. For the entire group, the number of MetS alterations was correlated with the leptin level and leptin:adiponectin ratio and adiponectin:leptin ratio after therapy. In conclusion, multicomponent therapy was effective in controlling the MetS, inflammation and cIMT in the obese adolescents. However, the MetS patients showed resistance in the attenuation of the atherogenic lipid profile and leptin:adiponectin ratio and adiponectin:leptin ratio. These results suggest that the MetS patients have increased cardiovascular risks, and that it is important to attempt to control the inflammatory process that occurs due to obesity in clinical practice in order to improve the health of adolescents.

RESUMO

OBJECTIVE: To compare the anesthetic efficacy and adverse effects associated with peribulbar injection of ropivacaine (1% solution) performed with and without ultrasound guidance (UG) in dogs. ANIMALS: 15 dogs without ophthalmologic abnormalities. PROCEDURES: Each dog was sedated and anesthetized. A peribulbar injection of ropivacaine (1% solution; 0.3 mL/kg) was performed with UG in 1 eye and without UG in the contralateral eye (control). For each eye, the intraocular pressure (IOP) immediately after eye centralization and number of punctures were recorded; ophthalmic complications, postinjection corneal sensitivity (determined by Cochet-Bonnet esthesiometry), durations of the sensory and motor blockades (the latter determined as the interval to restoration of the vestibuloocular reflex, pupillary light reflex, and conjugate eye movement), and blockade quality were assessed in both eyes following anesthetic recovery. RESULTS: Needle placement was fully visualized in 8 of the 15 eyes injected with UG. For eyes injected with or without UG, there was no difference with regard to the number of punctures, postinjection corneal sensitivity, and sensory or motor blockade duration and quality; however, restoration of conjugate eye movement occurred later in control eyes. For eyes injected with UG, mean IOP was 18.6 mm Hg, compared with 23.3 mm Hg for control eyes. Incidence of subconjunctival hemorrhage was higher for control eyes; severity of chemosis and hyperemia varied over time within both groups of eyes. CONCLUSION AND CLINICAL RELEVANCE: In dogs, peribulbar injection of ropivacaine with UG is feasible in dogs and provides effective sensory and motor blockades similar to those achieved with conventional techniques.

No presente estudo, foi investigada a qualidade microbiológica de 30 amostras de fitoterápicos derivados de 10 espécies vegetais vendidos em farmácias do Rio de Janeiro. Foram efetuadas as contagens totais de bactérias aeróbias, de bolores e leveduras, de outras enterobactérias e a identificação dos micro-organismos. Foram identificadas 17 espécies de bactérias e duas de fungos. A maioria dos micro-organismos era de agentes oportunistas, indicando que 80% das amostras avaliadas estavam insatisfatórias de acordo comos limites estabelecidos pela Farmacopeia Brasileira. Comparando-se os resultados deste trabalho com os relatados nos estudos anteriores, conclui-se que a contaminação em fitoterápicos é um problema que tem persistido ao longo do tempo, e o seu monitoramento microbiológico fornece base para ações de Vigilância Sanitária. Nesse contexto, o monitoramento desses medicamentos é relevante ferramenta para garantir a qualidade, a segurança e a eficácia desses produtos.

RESUMO

OBJECTIVE: To develop recommendations for the treatment of psoriatic arthritis (PsA) with biological therapies, endorsed by the Portuguese Society of Rheumatology. METHODS: These treatment recommendations were formulated by Portuguese rheumatologists based on literature evidence and consensus opinion. A draft of the recommendations was first circulated to all Portuguese rheumatologists and their suggestions were incorporated in the draft. At a national meeting the recommendations were discussed and all attending rheumatologists voted on the level of agreement for each recommendation. A second draft was again circulated before publication. RESULTS: A consensus was achieved regarding the initiation, assessment of response and switching biological therapies in patients with PsA. Specific recommendations were developed for several disease domains: peripheral arthritis, axial disease, enthesitis and dactylitis. CONCLUSION: These recommendations may be used for guidance in deciding which patients with PsA should be treated with biological therapies. They cover a rapidly evolving area of therapeutic intervention. As more evidence becomes available and more biological therapies are licensed, these recommendations will have to be updated.

RESUMO

INTRODUCTION: Obesity is related to numerous negative consequences for physical and mental health. It is often associated with the presence of binge eating disorder, body image dissatisfaction, and general psychopathology. OBJECTIVE: To assess the effects of an interdisciplinary lifestyle therapy on binge eating symptoms, depression, anxiety, body dissatisfaction, and quality of life in obese adults. METHODS: A total of 49 obese adults (body mass index = 37.35±5.82 kg/m²; age = 44.14±10.00 years) participated in a weight-loss program for 6 months. Symptoms suggestive of binge eating, body dissatisfaction, depression, anxiety, and quality of life were measured using self-reported questionnaires. Food intake was assessed using a 3-day dietary record. Data were analyzed using analysis of variance (ANOVA). RESULTS: ANOVA results showed a reduction in binge eating symptoms and in body dissatisfaction results. Depression and anxiety symptoms also decreased, and an increase was observed in quality of life scores. After therapy, a significant improvement was observed in dietary patterns, as well as significant weight loss. A positive correlation was found between variation of anxiety symptoms and lipid intake. Binge eating symptoms were associated with anxiety symptoms and body image dissatisfaction, and body image dissatisfaction correlated positively with anxiety symptoms in males only. In females, a positive correlation was observed between depression and binge eating symptoms. CONCLUSION: The interdisciplinary therapy was effective in promoting positive physical and psychological changes and in improving the quality of life of obese adults (AU)


INTRODUÇÃO: A obesidade se relaciona com inúmeras consequências negativas para a saúde física e mental. Está frequentemente associada com transtorno da compulsão alimentar periódica, insatisfação com a imagem corporal e psicopatologia geral. OBJETIVO: Avaliar os efeitos de uma terapia interdisciplinar de mudança do estilo de vida sobre sintomas de compulsão alimentar, depressão, ansiedade, insatisfação com a imagem corporal e qualidade de vida em adultos obesos. MÉTODOS: Um total de 49 adultos obesos (índice de massa corporal = 37.35±5.82 kg/m²; idade = 44.14±10.00 anos) participaram de um programa de redução de peso por 6 meses. Sintomas de compulsão alimentar, insatisfação com a imagem corporal, depressão, ansiedade e qualidade de vida foram avaliados por meio de questionários autoaplicáveis. O consumo alimentar foi avaliado utilizando-se um registro alimentar de 3 dias. Os dados foram analisados utilizando análise de variância (ANOVA). RESULTADOS: Os resultados da ANOVA mostraram uma redução nos sintomas de compulsão alimentar e na insatisfação com a imagem corporal. Os sintomas de depressão e ansiedade também diminuíram, e foi observado um aumento nos escores de qualidade de vida. Após a terapia, foi verificada melhora significativa no perfil nutricional, assim como significativa redução de peso. Foi observada uma correlação positiva entre a variação dos sintomas de ansiedade e o consumo de lipídios. Sintomas de compulsão alimentar apresentaram associação com sintomas de ansiedade e insatisfação com a imagem corporal, e a insatisfação com a imagem corporal se correlacionou positivamente com os sintomas de ansiedade nos homens. Nas mulheres, foi observada uma correlação positiva entre sintomas de depressão e de compulsão alimentar. CONCLUSÃO: A terapia interdisciplinar foi eficaz na promoção de mudanças físicas e psicológicas e proporcionou uma melhor qualidade de vida em adultos obesos (AU)

RESUMO

AIM OF THE STUDY: Genista tenera is a plant endemic to the island of Madeira and is used in folk medicine to control diabetes. In the present work we evaluate the antihyperglycaemic activity of its n-butanol extract and determine its chromatographic profile. In addition, this extract, the ethyl acetate and diethyl ether plant extracts were studied in order to assess the plant antioxidant and acetylcholinesterase inhibitory activities, as well as its cyto- and genotoxicities. MATERIALS AND METHODS: HPLC-DAD-ESI-MS was used to analyze the flavonoid profile of the n-butanol extract. The antihyperglycaemic activity of this extract was performed over streptozotocin induced diabetic Wistar rats (200 mg/kg, bw/day), for 15 days. Antioxidant activity (DPPH assay) and acetylcholinesterase inhibitory effect (Ellman method) were also performed. Acute cytotoxicity and genotoxicity were assessed by proliferative index quantification and the short-term chromosomal aberration technique, after exposure of lymphocytes to the extracts. RESULTS AND CONCLUSIONS: The n-butanol extract, where 21 monoglycosyl and 12 diglycosyl flavonoids were detected, significantly lowered blood glucose levels, bringing them to normal values after 15 days of treatment. The best radical scavenging activity was observed for the ethyl acetate extract (48.7% at 139.1 microg/mL), which was also the most effective one at the minimal concentration tested. The highest acetylcholinesterase inhibitory activity (77.0% at 70.0 microg/mL) was also obtained with the ethyl acetate extract. In vitro toxicity studies showed no evidence for acute cytotoxicity or genotoxicity. This is the first report on antidiabetic activity of genus Genista.

RESUMO

O Serviço de Atendimento do IEPP, instituição que visa à promoção do ensino da psicoterapia psicanalítica a psicólogos e médicos, foi criado com o objetivo de proporcionar a prática da psicoterapia aos psicoterapeutas em formação, funcionando, desta forma, como uma clínica-escola (C-e). O objetivo deste estudo foi conhecer a população que busca atendimento psicoterapêutico no IEPP. A amostra compreendeu 1102 pacientes que buscaram atendimento na instituição no período de dezembro de 1998 a junho de 2007. A análise dos dados se deu por estatística descritiva, compreendendo freqüências e porcentagens. Exploraram-se, neste estudo, características sociodemográficas, como sexo, faixa etária, escolaridade, ocupação, estado civil, por quem são encaminhados, o motivo da busca de atendimento e o desfecho do atendimento. A partir destes resultados, podemos aprofundar nosso conhecimento sobre esta demanda populacional, estando assim, mais bem preparados para atendê-la.(AU)

RESUMO

Genista tenera is endemic to the Portuguese island of Madeira, where an infusion of the aerial parts of the plant is used in folk medicine as an antidiabetic agent. Consequently the medicinal properties of the secondary metabolites of this plant have been the subject of an ongoing study. A recently reported LC-MS method using a 100 min separation allowed identification of five flavonoid components in an extract of the aerial parts of this plant. In order to obtain additional information on the range and complexity of the plant's secondary metabolite components a CE-MS method has been developed and applied for the analysis of an extract of G. tenera. Twenty-six different components are distinguished in an analysis time of only 10 min. Results demonstrate that CE-MS/MS rapidly generates data complementary to those obtainable by LC-MS/MS and is particularly suited to the analysis of plant metabolites where concentration is not limiting.
