Sarcopenia

Are designed landscapes conceived as geometric compositions or abstractions of nature incompatible with sustainable design? Does mimesis result in the only truly sustainable form in the landscape? This paper attempts to answer these questions by drawing on the observations of practitioners and educators in the field as well as investigating a range of built work for sustainable qualities. The built work is categorized according to four approaches to form genesis, geometric composition, abstractions of nature, mimesis, and combinations of the three. It is suggested here that there is no single formal strategy that must be used in order to achieve sustainability.

Background. Malnutrition is highly prevalent in hemodialysis (HD) patients. These patients have high levels of oxidative stress and inflammation which can subsequently induce malnutrition. Selenium levels have been found to be decreased in HD patients. As selenium deficiency leads to oxidative stress and inflammatory response, the aim of this study was to evaluate the effects of selenium supplementation on oxidative and inflammatory markers and the nutritional status of HD patients. Methods. In this randomized double-blind placebo-controlled trial, 80 patients on stable HD for at least 3 months without any acute illness or active infections were randomly allocated to two equal groups to receive one selenium (200 µg) or placebo capsule daily for 12 weeks. Serum levels of lipoproteins, malondialdehyde (MDA), interleukin-6 (IL-6), high-sensitivity C-reactive protein (HSCRP), homocysteine, ferritin and transferrin as well as the subjective global assessment (SGA) score, malnutrition–inflammation score (MIS) and hemoglobin (Hb) levels were measured at the baseline and at the end of the treatment phase. The primary outcome was a change in the nutritional status measured by the SGA score from the baseline towards the end of the treatment phase of the study. Results. The SGA score and MIS decreased significantly in the selenium group compared to the placebo group (P < 0.001 for both). Moreover, serum levels of MDA decreased significantly in the selenium group compared with increasing levels in the placebo group (P < 0.001). Selenium supplementation also hindered an increase in IL-6 levels compared with the placebo group (P = 0.016). There were no significant differences between the selenium and placebo groups in terms of changes in serum levels of lipoproteins, HSCRP, homocysteine, ferritin and transferrin or Hb levels.

Selenium supplementation improves the nutritional status of hemodialysis patients: a randomized, double-blind, placebo-controlled trial

Background and Aims Polycystic Ovarian Syndrome is a common reproductive, endocrine, and metabolic disease in women. Pomegranate juice, known as a rich source of phytochemicals with high antioxidant activity, enriched with probiotic may improve PCOS. Methods and Results A randomized, controlled, triple-blinded, parallel trial study was performed in PCOS patients (n = 92). Three treatment groups (23 patients each) received 2 L of synbiotic pomegranate juice (SPJ), pomegranate juice (PJ), and synbiotic beverage (SB) weekly. The control group (23 patients) received 2 L of placebo beverage weekly. Primary outcome was any change in insulin resistance and secondary outcomes were fasting blood sugar (FBS), insulin sensitivity, testosterone, luteinizing hormone (LH), follicle stimulating hormone (FSH), body mass index (BMI), waist and hip circumference, from baseline to the end of the trial. At the end of the study, 86 patients were analyzed. There was significant change in insulin resistance in the SPJ and SB groups. Insulin sensitivity increased significantly in the SPJ and SB groups. Insulin also changed significantly in the SPJ and SB groups. BMI, weight and waist circumference decreased significantly in the SPJ and SB groups. Testosterone level also decreased significantly in the SPJ and SB groups. There was no significant change in FPG, LH and FSH in any of the groups. Conclusion SPJ in the form of a new beverage can improve insulin resistance, insulin, testosterone level, BMI, weight and waist circumference in PCOS. This trial was registered in Iranian Registry of Clinical Trials, with number: 25272.

Effect of synbiotic pomegranate juice on glycemic, sex hormone profile and anthropometric indices in PCOS: A randomized, triple blind, controlled trial.

Background: Malnutrition, inflammation and poor quality of life are prevalent among hemodialysis (HD) patients. Health-related quality of life is an important determinant of hospitalization and mortality in HD patients. Objectives: The aim of this study was to assess the correlation between quality of life and malnutrition-inflammation status according to subjective global assessment (SGA) and malnutrition-inflammation scores (MIS) in HD patients. Patients and Methods: We randomly selected 87 of 180 stable HD patients from two HD centers. Those on hemodialysis for at least three months and with malnutrition according to the SGA scores were included in this study. They were divided into two groups of mild to moderate malnutrition (n = 39) and severe malnutrition (n = 49) based on the SGA scores. Serum levels of transferrin, albumin, blood urea nitrogen, creatinine, kt/v, body mass index and malnutrition-inflammation scores were measured in all patients. Health-related quality of life was assessed by validated short form-12 (SF-12) questionnaire for each patient. These values were compared between the two groups of patients by independent sample t-test and Mann-Whitney U test. The correlations of nutritional variables with SGA and MIS scores were determined by Pearson and Spearman correlation tests. Results: There were no differences in measured parameters between the two groups except for MIS scores. Those with severe malnutrition showed higher MIS scores. All quality of life aspects and total scores (PCS, MCS) (rather than social functioning (SF) aspect) were significantly different between the two groups, which showed lower physical and mental scores in severely-malnourished patients. Physical functioning (PF), role limitations due to physical heath (RP), general health (GH), mental health (MH), SF, role limitation due to emotional health (RE), vitality (VT) aspects and total scores (PCS and MCS) had negative significant correlations with MIS and SGA scores (All P values < 0.05). No correlation was found between MIS and SGA scores and other measured variables. Conclusions: This study focused on important effects of malnutrition and inflammation on health-related quality of life aspects, both physically and mentally in HD patients. SGA and MIS are highly correlated with quality of life in HD patients.
