Abstract

The global dementia epidemic now and in the future is mainly caused by the steady increase in the population of older persons, where around 2 billion people will be 60 years of age and older by 2050.(1,2) As a consequence, in that year  there will be 135 million people with dementia, particularly in low- and middle-income countries where 60% of the more than 47 million cases (2015 estimate) are living now.(2)

Abstract

BACKGROUNDElectronic waste (e-waste) is known to contain thousands of toxic chemicals and metals, many of which have identified endocrine disruption potentials even at low blood concentrations resulting from occupational and environmental exposures. E-waste crude reprocessing in Nigeria is massive and a growing number of Nigerians are occupationally exposed. The present study aimed to determine changes in gonadal hormone levels associated with occupational crude e-waste reprocessing in Nigerian male e-waste workers. METHODSThis cross-sectional study which was carried out in Benin City, South-South Nigeria recruited male e-waste workers (n=63); and apparently healthy non e-waste workers (n=41), as exposed and unexposed participants respectively. Male fertility hormones which includes luteinizing hormone (LH), follicle stimulating hormone (FSH), testosterone (TESTO) and prolactin (PROL); as well as progesterone (PROG), estrogen (EST) and inhibin (INH) were determined using enzyme linked immunosorbent assay (ELISA) methods; whole blood levels of chromium, cadmium, arsenic and mercury were determined using Inductively Coupled Plasma Mass Spectrometry. RESULTSLevels of TESTO, PROG, LH and FSH; as well as PROL and EST were significantly lower in e-waste workers compared with unexposed participants (p<0.05). In contrast, serum INH was significantly higher in e-waste exposed population compared with the unexposed. In addition, chromium correlated significantly and negatively with testosterone, progesterone and estrogen, while inhibin correlated positively with chromium. Similar correlation patterns were observed for cadmium, arsenic and mercury. CONCLUSIONNigerian e-waste workers experienced reduced levels of key gonadal hormones and this may be associated with occupational exposure to endocrine disrupting metals in e-waste.

Abstract

BACKGROUNDDry skin is a major skin health problem in elderly. Green tea, which has an antioxidant effect, has recently been used as an active ingredient in moisturizing creams; yet the effect has not been well studied. This study compares the skin hydration effect of green tea and vitamin E moisturizer among elderly.METHODSThis quasi-experimental study involved 60 elderly living in Tresna Werda Budi Mulia 4 Social Institution, Jakarta. Using the Runve HL 611 skin analyzer, skin capacitance was measured prior to experiment and every following week during the 5-week application of green tea and vitamin E skin moisturizer on both forearms. The consecutive measurement data was analyzed using Generalized Estimating Equation to compare the relative changes in skin hydration between the two moisturizer groups over 5 weeks of intervention. RESULTSThe green tea moisturizer showed more significant increases in skin hydration level than the vitamin E moisturizer at all measurement sites on right arm and proximal left arm (p= 0.021), and medial and distal left arm (p= 0.034). Skin hydration levels significantly changed over time at proximal (p=0.021), medial (p=0.006) and distal (p=0.006) right arm, and medial left arm (p=0.021). A parallel trend of skin hydration improvements for both moisturizer groups indicated no correlation between the moisturizer type and the duration of usage (p >0.05) in all measurement locations. No side effects were observed during application period in both groups.CONCLUSIONRoutine use of moisturizer containing green tea may improve skin hydration in elderly.

Abstract

BackgroundChronic and degenerative diseases are closely related to modern lifestyles that tend to be deficient in physical activity but excessive in food intake. One method used to overcome this problem is dietary restriction through intermittent fasting. Intermittent fasting decreases the risk of chronic and degenerative diseases, e.g. by lowering oxidative stress. Oxidative stress can be determined from the malondialdehyde (MDA) levels and lipid profile in the blood. The present study aimed to determine the effect of intermittent fasting on plasma MDA levels and lipid profile of Wistar rats (Rattus norvegicus).MethodsThis research was a laboratory experimental research using a post test control group design. Twenty four male Wistar rats (Rattus norvegicus) were randomly assigned to 4 groups, ie control group (C), fasting group (F), non-fasting obese group (NFO), and fasting obese group (FO). Fasting treatment given in this research was intermittent fasting, comprising one day of fasting for 12 hours alternating with one day of normal feed ad libitum in the span of 8 weeks. After completion of treatment, blood was taken transcardially for examination of MDA levels and lipid profiles using spectrophotometry.ResultsThere were significant between-group differences in MDA levels and lipid profiles (p<0.05 for all parameters). Groups treated with intermittent fasting had lower levels of MDA, total cholesterol, triglycerides, and ow-density lipoprotein (LDL) than those without intermittent fasting. The high-density lipoprotein (HDL) levels were higher in the intermittent fasting group than the other groups.ConclusionIntermittent fasting has an effect on the oxidative stress parameters of Wistar rats (Rattus norvegicus).
