Curcuminoid–Piperine Combination Improves Radical Scavenging Activity in Women with Premenstrual Syndrome and Dysmenorrhea: A Post-hoc Analysis of a Randomized Clinical Study / 전남의대학술지

Oxidative stress maybe involved in the patho-etiology of menstrual-associated complications. Curcuminoids, are polyphenolic natural compounds that have potentially important functional activities. This triple-blind, randomized, placebo-controlled trial was performed to investigate the effects of a curcuminoids on oxidative stress and antioxidant capacity in girls with premenstrual syndrome (PMS) and dysmenorrhea.Eighty young girls with both PMS and dysmenorrhea were randomly given either curcuminoids (500 mg+5 mg piperine) or a placebo daily, for a period from 7 days pre- until 3 days post- initiation of menstrual bleeding for 3 successive menstrual cycles. The total antioxidant capacity and free radical scavenging activity of serum and urine were quantified via ferric reducing/antioxidant power (FRAP) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) methods, respectively. There were no significant differences between the placebo and curcumin groups, with respect to the age, dietary intake and biochemical/anthropometric indices (p＞0.05). The curcumin treatment significantly increased the free-radical scavenging activity of serum compared to the treatment with placebo (p=0.031). Although, no significant changes were found in serum and urinary levels of FRAP, DPPH and MDA between the groups (p＞0.05). Curcumin treatment did increase free-radical scavenging activity and antioxidant potential in girls with PMS and dysmenorrhea. Investigations with higher doses and duration of curcumin are required to verify our findings.

Efficacy of Curcumin on Cognitive Function Scores in Women with Premenstrual Syndrome and Dysmenorrhea: A Triple-Blind, Placebo-Controlled Clinical Trial / 中国结合医学杂志

OBJECTIVE@#To assess the efficacy of a curcumin supplementation on cognitive abilities in women suffering from premenstrual syndrome (PMS) and dysmenorrhea.@*METHODS@#A randomized, triple-blind, placebo-controlled trial was conducted from December 2019 to March 2020. A total of 124 women who had both PMS and dysmenorrhea were enrolled, and were equally and randomly assigned to the curcumin group or placebo group, 62 cases in each. Each subject received either a capsule containing 500 mg of curcuminoid, or a placebo daily, for 10 days (7 days before and until 3 days after the onset of menstrual bleeding) over 3 menstrual cycles. The cognitive abilities questionnaire was used to measures cognitive functions in 7 specific areas. Adverse reactions were monitored during and after the trial in both groups.@*RESULTS@#Administration of curcumin was associated with a significant increase in memory score (P=0.002), inhibitory control and selective attention (P=0.020), and total cognitive ability task (P=0.024). In addition, significant increments were found in scores of memory (3.5±3.1 vs. 0.4±3.8 in the curcumin and placebo groups, respectively; P=0.035), inhibitory control and selective attention (3.0±3.7 vs. 0.4±3.7; P=0.027) and total cognitive abilities (8.3±12.3 vs. 2.2±12.4; P=0.025) in the curcumin group versus placebo groups. Curcumin was safe and well-tolerable in current clinical trial.@*CONCLUSION@#Curcumin has a beneficial efficacy on cognitive function scores in women with PMS and dysmenorrhea, with improvements in memory, inhibitory control and selective attention.

Malondialdehyde-modified LDL IgG antibody levels and indices of cardiac function in valvular heart and coronary artery disease patients

To compare the changes in anti-malondialde-hyde-modified low-density lipoprotein [MDA-LDL] IgG levels among patients undergoing off-pump and on-pump coronary artery bypass grafting [CABG] or valvuloplasty. A total of 38, 39 and 34 patients who underwent off-pump CABG, on-pump CABG and valvuloplasty, respectively, were enrolled in this study. Serum anti-MDA-LDL IgG values were measured 24 h before and after the operative procedures and at discharge. Echocardiogra-phy was also done before surgery and before discharge. The results were compared with values from 50 healthy controls. In all patients, a reduction in antibody titers was observed post-operatively. However, the decrease was significant only in the off-pump CABG - before surgery: 42.33 [25.83-58.51], after surgery: 30.86 [16.36-51.33] and at discharge: 10.96 [6.82-23.57; p = 0.027]. There was a significant positive association between anti-MDA-LDL IgG levels and ejection fraction [r = 0.248, p = 0.036] and a negative association with E/E', a marker of pulmonary capillary wedge pressure, in the coronary patients [r = -0.345, p = 0.012], but no significant associations were found in patients with valvular heart disease. Serum anti-MDA-LDL IgG levels were associated with cardiac function indices in coronary patients undergoing CABG

Dietary macronutrient intake of Saudi males and its relationship to classical coronary risk factors

To investigate whether the dietary intake of energy; macronutrients; and fiber differ between age groups, racial groups and socio-economic classes among males from the Western province of Kingdom of Saudi Arabia [KSA]. Data were collected from 303 male subjects, aged 15-80 years. They were selected randomly from King Abdul-Aziz University Hospital, Jeddah, KSA from October 2001 to November 2003 and grouped according to their age into 3 groups. The subjects were asked to complete a questionnaire concerning their demographic characteristics, health history, lifestyle, and dietary habits. Energy and carbohydrates intake fell with age [p<0.05]. Total dietary carbohydrates and fat intake were similar for all groups when expressed as a percentage of energy intake. The percentage energy as protein increased with age [p<0.05]. Mean cholesterol intake was high for all groups, but fell with age group [p<0.0001]. Saturated fat and monounsaturated fat intake, expressed as percentage energy intake were both high, whereas polyunsaturated fat intake was low. The youngest group had the highest percentage energy provided by saturated fatty acid [p<0.001], and the lowest percentage energy as polyunsaturated fatty acid [p<0.05] compared to the other groups. The intake of fibre rose with age was significantly higher in the older group [p<0.05]. Diet consumed by urban dwellers in KSA appears to have resulted in an imbalance of macronutrient intake among all sectors of the population. This problem can only be averted by raising public awareness and the development of appropriate population-specific nutritional guidelines
