RESUMO

Besides being scarce, the drugs available for treating cutaneous leishmaniasis have many adverse effects. Ozone is an option to enhance the standard treatment due to the wound-healing activity reported in the literature. In this study, we evaluated the efficiency of ozonated sunflower oil as an adjuvant in treating cutaneous lesions caused by Leishmania amazonensis. BALB/c mice were infected with L. amazonensis, and after the lesions appeared, they were treated in four different schedules using the drug treatment with meglumine antimoniate (Glucantime®), with or without ozonated oil. After thirty days of treatment, the lesions' thickness and their parasitic burden, blood leukocytes, production of NO and cytokines from peritoneal macrophages and lymph node cells were analyzed. The group treated with ozonated oil plus meglumine antimoniate showed the best performance, improving the lesion significantly. The parasitic burden showed that ozonated oil enhanced the leishmanicidal activity of the treatment, eliminating the parasites in the lesion. Besides, a decrease in the TNF levels from peritoneal macrophages and blood leukocytes demonstrated an immunomodulatory action of ozone in the ozonated oil-treated animals compared to the untreated group. Thus, ozonated sunflower oil therapy has been shown as an adjuvant in treating Leishmania lesions since this treatment enhanced the leishmanicidal and wound healing effects of meglumine antimoniate.

RESUMO

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is one of the most common liver diseases in the world. There is strong evidence that dyslipidemia and other cardio-metabolic disorders are highly prevalent in patients with NAFLD. This trial aimed at examining the effect of sesame oil (SO) in the context of a weight loss program on lipid profile, blood pressure, and anthropometric indices in women with NAFLD. METHODS: This randomized, double-blind, controlled trial was carried out on 60 women with NAFLD. Subjects were randomly assigned to the SO group (n = 30) and sunflower oil (SFO) group (n = 30), each person consuming 30 g of oil per day for 12 weeks. All the participants received a hypocaloric diet (- 500 kcal/day) during the study. Lipid profile, blood pressure, and anthropometric indices were assessed at pre- and post-intervention phases. RESULTS: In total, 53 participants completed the study. Following 12 weeks of intervention, anthropometric indices (p < 0.001) and systolic blood pressure (SBP) (p < 0.05) were significantly decreased in both groups and diastolic blood pressure (DBP) was significantly decreased in So group (p = 0.03). There was no significant change in lipid profile in both groups (p > 0.05). After adjusting for confounders, DBP (p = 0.031) and total cholesterol (TC) divided by high-density lipoprotein cholesterol (HDL-C) (p = 0.039) in the SO group were significantly reduced compared to the SFO group (p < 0.05). CONCLUSIONS: The present clinical trial revealed that SO and SFO may not differently affect anthropometric indices, SBP, and lipid profile except for TC/HDL-C. In addition, SO may be effective in improvement of DBP and TC/HDL-C compared to the SFO group. TRIAL REGISTRATION: Ethical approval of this trial was obtained at Isfahan University of Medical Sciences with the reference number of IR.MUI. RESEARCH: REC.1399.548 ( https://ethics. RESEARCH: ac.ir/ProposalCertificateEn.php?id=158942&Print=true&NoPrintHeader=true&NoPrintFooter=true&NoPrintPageBorder=true&LetterPrint=true ), and it was registered before the start of the patient recruitment on December 12th, 2020 in the Iranian Registry of Clinical Trials (IRCT) with the registration number of IRCT20140208016529N6 .

RESUMO

OBJECTIVES: Natural products are valuable sources of nutraceuticals for the prevention or treatment of ischemic stroke, a major cause of death and severe disability worldwide. Among the mechanisms implicated in cerebral ischemia-reperfusion damage, oxidative stress exerts a pivotal role in disease progression. Given the high antioxidant potential of most components of sunflower oil, we have explored its effects on ischemic brain injury produced in the mouse by transient occlusion of the middle cerebral artery (MCAo). KEY FINDINGS: Intraperitoneal (i.p.) administration of sunflower oil at doses of 3 ml/kg (48 h, 24 h and 1 h before MCAo) significantly reduced brain infarct volume and oedema assessed 24 h after the insult. This neuroprotective treatment schedule also prevented the elevation of brain lipid peroxidation produced by MCAo-reperfusion injury. By contrast, doses of 0.03 ml/kg of sunflower oil resulted ineffective on both cerebral damage and lipid peroxidation. Although sunflower oil did not affect serum levels of Diacron-reactive oxygen metabolites (d-ROMs), both 0.03 and 3 ml/kg dosing regimens resulted in the preservation of serum biological antioxidant potential (BAP) that was otherwise dramatically reduced 24 h after MCAo. CONCLUSIONS: Sunflower oil represents a promising source of neuroprotective extracts/compounds that can be exploited for the prevention and/or treatment of cerebral ischemia.

RESUMO

BACKGROUND: Hospitalized preterm infants with compromised skin barrier function treated topically with sunflower seed oil (SSO) have shown reductions in sepsis and neonatal mortality rate (NMR). Mustard oil and products commonly used in high-mortality settings may possibly harm skin barrier integrity and enhance risk of infection and mortality in newborn infants. We hypothesized that SSO therapy may reduce NMR in such settings. METHODS AND FINDINGS: This was a population-based, cluster randomized, controlled trial in 276 clusters in rural Uttar Pradesh, India. All newborn infants identified through population-based surveillance in the study clusters within 7 days of delivery were enrolled from November 2014 to October 2016. Exclusive, 3 times daily, gentle applications of 10 ml of SSO to newborn infants by families throughout the neonatal period were recommended in intervention clusters (n = 138 clusters); infants in comparison clusters (n = 138 clusters) received usual care, such as massage practice typically with mustard oil. Primary analysis was by intention-to-treat with NMR and post-24-hour NMR as the primary outcomes. Secondary analysis included per-protocol analysis and subgroup analyses for NMR. Regression analysis was adjusted for caste, first-visit weight, delivery attendant, gravidity, maternal age, maternal education, sex of the infant, and multiple births. We enrolled 13,478 (52.2% male, mean weight: 2,575.0 grams ± standard deviation [SD] 521.0) and 13,109 (52.0% male, mean weight: 2,607.0 grams ± SD 509.0) newborn infants in the intervention and comparison clusters, respectively. We found no overall difference in NMR in the intervention versus the comparison clusters [adjusted odds ratio (aOR) 0.96, 95% confidence interval (CI) 0.84 to 1.11, p = 0.61]. Acceptance of SSO in the intervention arm was high at 89.3%, but adherence to exclusive applications of SSO was 30.4%. Per-protocol analysis showed a significant 58% (95% CI 42% to 69%, p < 0.01) reduction in mortality among infants in the intervention group who were treated exclusively with SSO as intended versus infants in the comparison group who received exclusive applications of mustard oil. A significant 52% (95% CI 12% to 74%, p = 0.02) reduction in NMR was observed in the subgroup of infants weighing ≤1,500 g (n = 589); there were no statistically significant differences in other prespecified subgroup comparisons by low birth weight (LBW), birthplace, and wealth. No severe adverse events (SAEs) were attributable to the intervention. The study was limited by inability to mask allocation to study workers or participants and by measurement of emollient use based on caregiver responses and not actual observation. CONCLUSIONS: In this trial, we observed that promotion of SSO therapy universally for all newborn infants was not effective in reducing NMR. However, this result may not necessarily establish equivalence between SSO and mustard oil massage in light of our secondary findings. Mortality reduction in the subgroup of infants ≤1,500 g was consistent with previous hospital-based efficacy studies, potentially extending the applicability of emollient therapy in very low-birth-weight (VLBW) infants along the facility-community continuum. Further research is recommended to develop and evaluate therapeutic regimens and continuum of care delivery strategies for emollient therapy for newborn infants at highest risk of compromised skin barrier function.

RESUMO

OBJECTIVE: To investigate the effect of sunflower seed oil (SSO) and almond oil (AO) on stratum corneum hydration and Neonatal Skin Condition Scores (NSCSs) of preterm infants. METHODS: This randomized controlled trial recruited 90 preterm infants whose gestational ages were between 32 and 37 weeks in the neonatal ICU. Infants were randomly assigned to three groups (SSO, AO, or control). The oils were applied to the whole body of each infant except for the head and face by a nurse researcher four times a day (4 mL/kg) for 5 days. MAIN OUTCOME MEASURES: Skin condition of the infants as evaluated with the NSCS; hydration as measured by a skin moisture meter before and after application. MAIN RESULTS: When average stratum corneum hydration was compared, infants in the SSO and AO groups had better hydration than infants in the control group. The NSCS scores in the control group were significantly higher than in the intervention groups, but there was no difference between the SSO and AO groups. CONCLUSIONS: Neither SSO nor AO has harmful effects on the skin, and their use may improve stratum corneum hydration. These oils can be used by nurses to hydrate the skin of preterm infants. Further studies are needed to evaluate the efficacy of natural oils on infant skin.

RESUMO

Oral applications of peroxidised sunflower oil (PSO) cause development of nephropathy, which can be prevented with the help of oral applications of the Biotrit phytogel containing bioflavonoids from wheat seedlings. The purpose of this work was to determine the renoprotective effect of the Biotrit phytogel under the influence of PSO on rats. The experiments were carried out on 18 white Wistar rats (females, 4-5 months, 210±12 g), divided into 3 equal groups: the first - control, received compound feed. The 2nd and 3rd groups received the same diet; however, they additionally undergo oral applications of PSO at a dose of 0.5 ml per rat daily for 5 days. Rats of the 3rd group 30 minutes before the application of PSO received application of the "Biotrit" gel in a dose of 0.5 ml per rat for 5 days. After euthanasia of animals, kidneys were removed on the 6th day and the level of biochemical markers of inflammation and the content of malonic dialdehyde (MDA), urease and lysozyme were determined in the homogenate of the latter. Under the action of PSO both indicators significantly increase: elastase activity by 20%, and MDA content by 50%. Oral applications of the "Biotrit" gel reduce both indicators of inflammation. Catalase activity does not change both with the introduction of PSO and after application of the Biotrit gel. In rats treated with PSO, urease activity in the kidneys significantly increases, indicating an increase in bacterial contamination, which decreases under the influence of oral applications of the Biotrit gel. The consumption of peroxidised fats causes the development of nephropathy in experimental animals. To prevent the development of peroxide nephropathy, one can use oral applications of "Biotrit" phytogel.

RESUMO

Se realizó un ensayo clínico en fase IV para evaluar la efectividad del Oleozón® aplicado por vía oral en niños y adolescentes con giardiasis, atendidos en la interconsulta de Pediatría del Policlínico Universitario Julián Grimau García de Santiago de Cuba, desde enero hasta diciembre del 2015. El universo estuvo constituido por 116 pacientes (con igual número de casos y controles) en las edades de 1 a 18 años, infectados por Giardia lamblia, quienes presentaban dolor abdominal, vómito y anorexia como síntomas fundamentales. En la serie se obtuvo que el mayor número de los pacientes del grupo experimental, cuyo esquema terapéutico incluía el Oleozón®, resolvió el dolor abdominal y mejoró su estado general al disminuir el resto de los síntomas. Pudo concluirse que el Oleozón® resultó efectivo en el tratamiento contra la giardiasis, pues las muestras de heces fecales dieron negativo en todos los casos; además, no se produjeron reacciones adversas y su costo es bajo, lo que conlleva un impacto económico, social y medioambiental


A clinical assay in phase IV was carried out to evaluate the effectiveness of oral Oleozón® used in children and adolescents with giardiasis, assisted in the Pediatrics specialty consultation from Julián Grimau García University Polyclinic in Santiago de Cuba, from January to December, 2015. The universe was constituted by 116 patients (with the same number of cases and controls) and aged 1 to 18 years, infected by Giardia lamblia who presented abdominal pain, vomit and anorexy as fundamental symptoms. In the series it was obtained that the highest number in the patients of the experimental group whose therapeutic schedule included Oleozón® , solved the abdominal pain and it improved their general state when decreasing the rest of the symptoms. It could be concluded that the Oleozón® was effective in the treatment against giardiasis, because the samples of faeces were negative in all cases; besides, it produced no adverse reactions and its cost is low, what bears an economic, social and environmental impact

RESUMO

BACKGROUND: Metabolic syndrome (MetSyn) increases the risk of type II diabetes and morbidity and mortality due to cardiovascular diseases. Flaxseed oil (FO), as a functional food, is one of the major vegetal sources of essential omega-3 fatty acids. OBJECTIVE: This study aimed to compare the effects of consumption of FO and sunflower seed oil (SO) on lipid peroxidation and other symptoms of MetSyn. METHODS: This randomized controlled interventional trial was conducted on 60 volunteers aged 30 to 60 years who were diagnosed with MetSyn in Shiraz, Iran. The participants who fulfilled the inclusion criteria were randomly assigned to SO (n = 30, receiving 25 mL/d SO) and FO (n = 30, receiving 25 ml/d FO) groups using block randomization. The diets were identical for all the participants. Blood pressure (BP), serum lipid, fasting blood sugar, and malondialdehyde were measured at baseline and at the end of week 7. RESULT: The results showed no significant difference between the 2 groups regarding blood lipid levels and fasting blood sugar at the end of the study. However, significant reductions in total cholesterol, low-density lipoprotein cholesterol (5.6% in FO and 10.8% in SO), and triglyceride levels were seen within each group after treatment with FO and SO (P < .05). Nonetheless, between-group changes were significant (<0.05) for systolic BP (mean [±standard deviation {SD}] changes were -14.0 ± 22.41 in the FO group [P = .004] and 0.92 ± 8.70 in the SO group [P = .594]) and diastolic BP (mean [±SD] changes were -4.26 ± 7.44 in the FO group [P = .007] and 1.30 ± 6.91 in the SO group [P = .344]), but marginally significant (P = .053) for malondialdehyde level (mean [±SD] changes were -1.29 ± 1.48 in the FO group [P < .001] and -0.52 ± 1.34 in the SO group [P = .52]). A significant decrease in weight was also found in both groups. However, waist circumference decreased significantly only in the FO group at the end of the study (P < .05). CONCLUSION: Our results indicated that dietary FO could be effective in amelioration of some symptoms of MetSyn and decrease BP and lipid peroxidation.

RESUMO

INTRODUCTION: Corticosteroids are the mainstay of treatment for the acute phase of atopic dermatitis (AD), whereas topical emollients are mainly used for maintenance of remission. A topical agent that combines emollient and anti-inflammatory properties would achieve control of all phases of AD, without the need for chronic corticosteroid use. AIM: To assess the efficacy of a novel topical agent containing superoxide dismutase (SOD) 100 000 IU and 4% of a combination of plant extracts (blackcurrant seed oil, sunflower oil concentrate, balloon vine extract). METHODS: Twenty patients (age range from 8 months to 72 years old) with mild-to-moderate atopic dermatitis were assessed. The product was used as mono-therapy, applied to the affected skin areas twice daily. Patients were evaluated before and after a 30-day course using the SCORAD and the Visual Analog Scale for assessment of pruritus intensity. Primary endpoint was improvement of AD according to SCORAD and clinical assessment. Secondary endpoint was patient satisfaction and improvement of pruritus. RESULTS: Mean SCORAD on day 0 was 32.61(range = 16.0-46.9) and decreased to 10.55 (range = 0-17.0) on day 30, reflecting a reduction of 67.6%. On day 30, all patients described significant improvement in pruritus and quality of sleep. CONCLUSION: The application of the study product cream resulted in significant improvement of AD, as reflected by the objective SCORAD measurement, and the subjective assessment of pruritus and quality of life. This novel anti-inflammatory emollient product may emerge as a safe and effective therapeutic tool for all phases of AD without the adverse effects of chronic use of corticosteroids.

RESUMO

The potential of fish or fish oil as supplier for eicosapentaenoic acid (EPA, C20:5n3) and docosahexaenoic acid (DHA, C22:6n3) for reducing cardiovascular risk factors and supporting therapy of chronic inflammatory diseases, has been investigated intensively, but our knowledge about the physiological effects of the individual compounds EPA and DHA are limited. STUDY DESIGN: In this double-blind pilot study, thirty-eight patients with defined RA were allocated to consume foods enriched with microalgae oil from Schizochytrium sp. (2.1 g DHA/d) or sunflower oil (placebo) for 10 weeks (cross-over), maintaining the regular RA medication during the study. RESULTS: In contrast to placebo, the daily consumption of DHA led to a decline in the sum of tender and swollen joints (68/66) from 13.9 ± 7.4 to 9.9 ± 7.0 (p = 0.010), total DAS28 from 4.3 ± 1.0 to 3.9 ± 1.2 (p = 0.072), and ultrasound score (US-7) from 15.1 ± 9.5 to 12.4 ± 7.0 (p = 0.160). The consumption of placebo products caused an increase of the n-6 PUFA linoleic acid and arachidonic acid (AA) in erythrocyte lipids (EL, p < 0.05). The amount of DHA was doubled in EL of DHA-supplemented patients and the ratios of AA/EPA and AA/DHA dropped significantly. We speculate that the production of pro-inflammatory/non-resolving AA-derived eicosanoids might decrease in relation to anti-inflammatory/pro-resolving DHA- and EPA-derived lipid mediators. In fact, plasma concentrations of AA-derived thromboxane B2 and the capacity of blood to convert AA to the pro-inflammatory 5-lipoxygenase product 5-hydroxyeicosatetraenoic acid were significantly reduced, while levels of the DHA-derived maresin/resolvin precursors 14-/17-hydroxydocosahexaenoic acid significantly increased due to DHA supplementation. CONCLUSION: The study shows for the first time that supplemented microalgae DHA ameliorates disease activity in patients with RA along with a shift in the balance of AA- and DHA-derived lipid mediators towards an anti-inflammatory/pro-resolving state.

RESUMO

BACKGROUND: Neonates undergoing surgery are at risk for uncontrolled inflammatory response and adverse clinical outcomes. Docosahexaenoic acid (DHA) ameliorates inflammation, improving clinical outcomes. However, its effect has not been evaluated in neonates undergoing surgery. We evaluated the effect of DHA on markers of inflammation and clinical outcomes in neonates undergoing surgery. METHODS: A double-blind clinical trial evaluated the effect of enteral DHA (DHA group) versus sunflower oil (SO group) perioperatively administered in neonates scheduled for cardiovascular surgery. Inflammation was evaluated by percentage of cells+ for cytokines and CD69 in mononuclear cells at baseline, 24 h and 7 days post surgery. Clinical outcomes measured were sepsis, organ dysfunctions (ODs), length of stay in intensive care and bleeding. Repeated measures analysis of variance and logistic regression were applied. RESULTS: Sixteen neonates received DHA and 18 received SO. Cells+ from neonates in the DHA group showed an early increase in receptor antagonist of interleukin (IL)-1+ (IL-1ra+) and IL-10+ and a late decrease in IL-6+. IL-1ß+ and IL-10+ changes were different between groups. After adjusting for confounders, less cells from DHA group were IL-1ß+, IL-6+, IL-1ra+ and IL-10+. DHA group presented less sepsis, ODs and shorter stay, but no difference in CD69+CD4+ cells or bleeding between groups. CONCLUSIONS: Administration of enteral DHA ameliorates markers of inflammation and improves clinical outcomes in surgical neonates.

RESUMO

BACKGROUND & AIMS: Gestational diabetes mellitus (GDM) compromises the level of docosahexaenoic acid (DHA) in phospholipids of maternal and fetal red blood cells and fetal plasma. This is of some concern because of the importance of DHA for fetal neuro-visual development. We have investigated whether this abnormality could be rectified by supplementation with DHA-enriched formula. METHODS: Women with GDM (n = 138) recruited from Newham University Hospital, London received two capsules of DHA-enriched formula (active-group) or high oleic acid sunflower seed oil (placebo-group) from diagnosis until delivery. Maternal (baseline and delivery) and fetal (cord blood) red blood cell and plasma phospholipid fatty acid composition, and neonatal anthropometry were assessed. RESULTS: One hundred and fourteen women (58 active, 56 placebo) completed the trial. The active-group compared with the placebo-group had significantly enhanced level of DHA in plasma phosphatidylcholine (4.5% vs 3.8%, P = 0.011), red blood cell phosphatidylcholine (2.7% vs 2.2%, P = 0.022) and phosphatidylethoanolamine (9.5% vs 7.6%, P = 0.002). There was no difference in cord plasma and red blood cell phospholipid DHA between the two groups. The neonates of the two groups of women had comparable anthropometric measurements at birth. CONCLUSION: Daily supplementation of 600 mg DHA enhances maternal but not fetal DHA status in pregnancy complicated by GDM. The inefficacy of the supplement to improve fetal status suggests that the transfer of DHA across the placenta maybe impaired in women with the condition. Regardless of the mechanisms responsible for the impairment of the transfer, the finding has implications for the management of neonates of women with GDM because they are born with a reduced level of DHA and the condition is thought to be associated with a risk of neuro-developmental deficits. We suggest that babies of women with GDM, particularly those not suckling, similar to the babies born prematurely require formula milk fortified with a higher level of DHA.
