RESUMO

Background: Urtica pilulifera L. seed (UPS) is a Persian traditional medicine prescription that positively affects female infertility. Objective: This study aimed to evaluate the beneficial effects of UPS on a diminished ovarian reserve (DOR) model induced by cyclophosphamide in Balb/c mice. Materials and Methods: A single intraperitoneal (75 mg/kg) of cyclophosphamide was administered to establish a DOR model. 25 female Balb/c mice (6-8 wk, 25 ± 2 gr) were randomly divided into 5 groups (n = 5/each), including control (normal saline), model (DOR), DOR+50, DOR+100, and DOR+200 (mg/kg UPS, gavage) groups for 14 days. The levels of follicle-stimulating hormone, luteinizing hormone, estradiol, malondialdehyde, superoxide dismutases, apoptosis, and histopathological alterations were analyzed. Gas chromatography-mass spectrometry analysis was performed to identify the phytochemicals of the UPS. Results: It was observed that the UPS extract reduced malondialdehyde concentration and apoptosis in the DOR model as well as enhanced superoxide dismutases activity in the ovaries in a dose-dependent manner. Moreover, it exerted a modulatory effect on steroidal hormones such as follicle-stimulating hormone, luteinizing hormone, and estradiol. The histopathological analysis revealed the therapeutic potential of the UPS extract. The main chemical components of UPS were linoleic acid (59.25%), n-hexadecanoic acid (10.36%), and oleic acid (8.29%). Conclusion: The results indicated that the UPS extract has therapeutic potential in the DOR model. This potential is attributed to the reduction of oxidative stress, modulation of apoptosis, and regulation of steroidal hormones that may be associated with the observed beneficial effects of fatty acids on fertility improvement.

RESUMO

PURPOSE: Patient satisfaction with hospital food enhances consumption and adequate intake of nutrients required for recovery from illness/injury and maintenance of health; accordingly, the nutrient content of the menu must balance patient preferences. This study of Ontario hospital foodservice departments collected data on current practices of analyzing the nutritional adequacy and assessing patient satisfaction with menus, and it explored perceptions of priority issues. METHODS: Foodservice managers/directors from 57 of 140 (41%) hospitals responded to cross-sectional in-depth telephone interviews. Deductive analysis of responses to open-ended questions supplemented quantitative data from closed-ended questions. RESULTS: The hospitals without long-term care facilities (LTCFs) assessed regular (58%), therapeutic (53%), and texture-modified (47%) menus for nutritional adequacy. This differed from hospitals governing LTCFs where there was a higher frequency of assessment of regular (75%), therapeutic (75%), and textured-modified (66%) menus. Most departments (86%-94%) obtained patient satisfaction feedback at the departmental/corporate levels. Many identified budget and labour issues as priorities rather than assessing menus for nutritional adequacy and patient satisfaction. CONCLUSIONS: Hospital menus were not consistently assessed for nutritional adequacy and patient satisfaction; common assessment methodologies and standards were absent. Compliance standards seem to increase the frequency of menu assessment as demonstrated by hospitals governing LTCFs.

RESUMO

The Human Immunodeficiency Virus has devastating effects worldwide. The burden is less pronounced, but still present in Canada where approximately 64,000 men and women are HIV positive. The virus and the life-saving antiretroviral therapies often contribute to diarrhea and other gastrointestinal disturbances. Certain probiotic organisms, such as Lactobacillus rhamnosus GR-1, have been shown to alleviate diarrhea as well as delay the decline of CD4 lymphocytes in some subjects. In addition, micronutrient formulae have been used extensively among HIV positive persons as a cost-effective method for improving quality of life and immune function. The objective of the present study was to combine probiotics and micronutrients into an affordable and highly palatable nutritional supplement and assess outcomes in 21 HIV-positive participants receiving highly active antiretroviral therapy in London, Ontario, Canada. The design was a randomized, double blind, three-period, cross-over controlled trial with three different formulations of supplemented yogurt; micronutrient and probiotic (A), micronutrient alone (B) and probiotic alone (C). The period of intake for each of the types was 30 days with a 14 day wash-out period between the intervention types. The mean increase in CD4 was greatest with B (41 cells/µL, SD 221). Supplement A showed a mean change of +19 cells/µL (SD 142) and supplement C a mean change of - 7 cells/µL (SD 154). All yogurt types caused an increase in subjective energy and ability to perform daily activity scores. According to the safety measures taken to assess the tolerance of the yogurt, there were no adverse events and the yogurt was well-tolerated. These preliminary findings suggest that micronutrient supplemented probiotic yogurt may support immune function among people living with HIV.

RESUMO

The gut-associated lymphoid tissue is a major site of human immunodeficiency virus (HIV) activity and significantly influences disease prognosis. Reducing immune activation due to gastroenteritis may thus help slow disease progression. Probiotic microorganisms have considerable immunomodulatory effects at the level of the gut-associated lymphoid tissue. A probiotic yogurt initiative was thus established in Mwanza, Tanzania, to improve gastrointestinal (GI) integrity and reduce the incidence and severity of opportunistic infections among people with HIV. The research objective was to retrospectively evaluate the effects of yogurt supplemented with Lactobacillus rhamnosus as an adjunct to the diet of people living with HIV on systemic and GI symptoms, daily routine activities, and nutritional intake. Eighty-five people with HIV consuming probiotic yogurt and 86 controls were interviewed. Demographics and HIV disease stage were comparable between groups. Probiotic yogurt consumers reported an ability to work a median of 2 hours more daily (P = .01), experienced a lower fever incidence (P = .01), and were more likely to achieve daily nutrient requirements for vitamin A, several B complex vitamins, and calcium (P = .02). Antiretroviral users experienced less drug-induced stomach pain (P = .02) and a lower overall impact of GI symptoms on routine activities (P = .03). The results of this study need be further substantiated because of limits imposed by the observational, retrospective study design; however, results suggest that yogurt supplemented with L rhamnosus may effectively alleviate GI symptoms and improve productivity, nutritional intake, and tolerance to antiretroviral treatment among people with HIV in Mwanza.

RESUMO

BACKGROUND: Micronutrient supplementation has been shown to reduce the progression of HIV but does not have an effect on the intestinal barrier or the intestinal microbiota of HIV patients. Studies have suggested that probiotics could potentially complement micronutrients in preserving the immune-function of HIV patients. OBJECTIVE: Assess the impact of micronutrient supplemented probiotic yogurt on the immune function of HIV patients. DESIGN: We performed a randomized, double blind, controlled trial with CD4 count as primary outcome among HIV patients naïve to anti-retroviral treatment. Secondary outcomes included hematological parameters, incidence of diarrhea and clinical symptoms. A total of 112 HIV patients were randomized to receive a micronutrient fortified yogurt with (n = 55) or without additional probiotic Lactobacillus rhamnosus GR-1 (n = 57) for four weeks. RESULTS: An average decline in CD4 count of -70 cells/µL (95% CI: -154 to -15) was observed in the micronutrient, probiotic group versus a decrease of -63 cells/µL (95% CI: -157 to -30) in the micronutrient control group (p = 0.9). Additional probiotic supplementation was well tolerated and not associated with adverse events. No difference between groups was detected in incidence of diarrhea or clinical symptoms. An improvement of hemoglobin levels was observed for all subjects, based upon a mean difference from baseline of 1.4 g/L (SD = 6) (p = 0.02). CONCLUSION: The addition of probiotics to a micronutrient fortified yogurt was well tolerated by HIV patients but was not associated with a further increase in CD4 count after one month.

RESUMO

Microbial exposure may direct the immune system away from allergic-type responses, but until now probiotic interventions have had limited success in the prevention and treatment of allergic diseases. In this study, a novel probiotic mixture was specifically created based on preliminary in vitro investigations on pollen-induced immune responses. A mixture with Lactobacillus rhamnosus GR-1 and a novel fecal Bifidobacterium adolescentis isolate was formulated into a yogurt and tested for its effects in 36 subjects with allergic rhinitis over 2 pollen seasons in a double-blind, placebo-controlled trial. The new formulation was well tolerated, but did not have significant effects on the quality of life scores, use of antihistamines, or eosinophil cationic protein concentration in nasal lavage. However, at the end of the grass pollen season, serum IL-10 and IL-12 levels were increased in the probiotic group compared to the controls. During the ragweed season, the serum TGF-β levels were significantly higher in the probiotic group than in the controls. In conclusion, the novel probiotic formulation had potentially desirable effects on the cytokine profile of patients with allergic rhinitis, but provided few clinical benefits. The study highlights the challenges in designing efficient immunomodulatory probiotic therapies based upon in vitro findings.

RESUMO

Epidemiology of minor burns is not well defined worldwide. The aim of this study was to examine epidemiological features of minor and moderate burn events that could be beneficial for prevention purposes. The study was conducted in Ardabil province in north-west Iran in 2005-2006. A total of 1700 minor and moderate burns were studied using a pretested questionnaire. Using the SAS 9.1 statistical program analyses were made. Females comprised the majority of cases (n=1000, 58.8%) and children, aged six and younger, made up 36.4% of burn victims. The majority of burns were caused by hot water and tea with the primary containers being kettles in 37.8%, cups or glasses in 24.2%, pots in 13.6% and samovars in 7.9%. Samovars, gas stoves, valors and picnic gas stoves were the primary heating devices involved in burns. In 56% of the cases, overturning of liquid containers was the primary injury mechanism of scalds. 43% had a second-degree burn with a mean total body surface area of 1.3%. This study provides possible beneficial information for burn prevention in the Ardabil area and other similar settings.
