Abstract

BackgroundNutrition has come to the fore as one of the major modifiable determinants of chronic disease. Establishing healthy eating habits during adolescence is important given that fruit and vegetable consumption has long-term health-protective benefits. The objective of this study was to investigate the determinant factors of fruit and vegetable consumption habits among Padang inhabitants MethodsWe conducted a questionnaire-based rapid assessment of 150 respondents who came from different settings: The questionnaire consisted of items on personal characteristics such as age, working status, gender, and personal knowledge of the subjects about the cause of non-communicable diseases (NCDs) and their activities to prevent NCDs. Bivariate analysis was applied to look for variables significantly related to healthy eating (vegetable and fruit consumption). We applied multiple logistic regression to look for the best model to explain factors related to regular fruit and vegetable consumption.Results The age range of the subjects was 14 to 76 years, 60% of subjects were women, and 40% were men. The study indicated that 64.7% of the respondents perceived that eating habits relate to NCD, while 67.3% consumed fruits and vegetables regularly. Multivariate logistic regression analysis indicated that gender (O.R.=2.74; 95% C.I. 1.54-5.27) and perception of NCD as being related to healthy eating (O.R.=5.62;95% C.I. 2.93-10.76) were significantly related to regular fruit and vegetable consumption. ConclusionThis study demonstrated that perception of NCD was the most determinant factor of regular fruit and vegetable consumption. Activities to improve practice of regular fruit and vegetable consumption are part of control of NCD risk factors.

Abstract

BACKGROUNDNeoplastic and non-neoplastic oral mucosal growths often have a variety of clinical manifestations according to their biological nature. Immunohistochemical diagnostic markers, such as Ki-67, are used to detect their proliferation and differentiation. Ki-67 is expressed in all phases of the cell cycle, except G0. The objective of this study was to determine Ki-67 expression in benign, malignant and non-neoplastic proliferation of oral mucosal epithelium.METHODSA laboratory study of cross sectional design was conducted using samples from excised oral mucosa diagnosed as inflammatory gingival hypertrophy (n=5); epulis (n=6); gingival polyps (n=5); pulpal polyps (n=5); papilloma (n=3) and squamous cell carcinoma (n=2). The antigen retrieval endogenous peroxidaseblock method was used in the application of Ki-67 primary  antibody and chromogen to display the antigen antibody reaction, with positive  cells showing brown nucleoplasm staining. The Ki-67 positive index was calculated by dividing the number of positive epithelial cells with the total number of epithelialcells in the areas observed at 400x magnification. One-way ANOVA was used to compare the Ki-67 indexes of neoplastic and non-neoplastic lesions.RESULTSThe highest Ki-67 positive index was for squamous cell carcinoma (64.55 ± 23.55%) followed by papilloma (23.33 ± 6.94%), gingival polyps (7.06 ± 7.43%) and gingival hypertrophy (1.40 ± 2.80%). One-way ANOVA showed significant differences in Ki-67 expression between neoplastic and non-neoplastic  samples (p<0.05).CONCLUSIONSThe high Ki-67 expression in neoplasms is proportional to the  grade of malignancy. In non-neoplastic processes Ki-67 expression is merely an adaptive response and does not indicate increased Ki-67 proliferative gene expression.

Abstract

In developing countries there still are differentials in immunization coverage between regions, such as in Indonesia for measles vaccination between urban and rural regions, as reported in 2007.(1) Therefore, it may not be surprising to hear about local or even national outbreaks of communicable disease in these countries. However, that an epidemic should occur in developed nations with relatively complete immunization coverage, comes somewhat as a surprise. The epidemic referred to is the whooping-cough epidemic occurring this year in the USA, and on a smaller scale in Europe, particularly in the UK.

Abstract

BACKGROUND Total testosterone (TT) levels in males decrease with age. There has been a vigorous debate on the extent to which low testosterone causally contributes to diabetes and its complications. The aim of the present study was to determine the relationship between sex hormones and blood glucose levels in adult males. METHODS A cross-sectional study involving 259 males aged 41 - 70 years was conducted at Cilandak Subdistrict, South Jakarta. Sex hormone binding globulin (SHBG) and testosterone levels were measured by means of electro–chemiluminescent immunoassay (ECLIA), while blood glucose levels were measured enzymatically using a spectrophotometer. Free testosterone index (FTI) and body massa index (BMI) were calculated. Inter-variable relationships were tested by Pearson correlation analysis, followed by multiple linear regression analysis to determine the most influential factor on fasting blood glucose levels. RESULTS BMI was positively correlated with fasting blood glucose, but the correlation was statistically not significant (r=0.105; p=0.106). In contrast, total testosterone (TT) (r=-0.258; p=0.000) and SHBG (r=-0.193; p=0.02) had a significant negative correlation with fasting blood glucose level. Multiple linear regression showed that TT was the most influential factor on fasting blood glucose level (â=-0.044; p=0.008). CONCLUSIONS Low total testosterone level may increase fasting blood glucose level in adult males. SHBG levels did not predict fasting blood glucose levels.Assessment of testosterone in middle-aged men may allow early intervention for diabetes mellitus.

Abstract

BACKGROUND Lead is still a major environmental and occupational health hazard, since it is extensively used in the production of paints, gasoline and cosmetics. This causes the metal to be ubiquitous in the environment, being found in the air, soil, and water, from which it can enter the human body by inhalation or ingestion. Absorbed lead is capable of altering the calcium levels in bone. The aim of this study was to demonstrate the effect of lead on bone calcium levels by measuring the reaction constant, Gibbs free energy, and enthalpy. METHODS This study was of pure experimental design using 100 male albino rats (Rattus norvegicus). The experimental animals were assigned by simple randomization to two groups, one group receiving lead acetate orally at a dosage of 100 mg/ kgBW, while the other group did not receive lead acetate. The intervention was given for 4 weeks and the rats were observed weekly for measurement of bone calcium levels by the permanganometric method. RESULTS This study found that k1 (hydroxyapatite dissociation rate constant) was 0.90 x 10-3 dt-1, and that k2 (hydroxyapatite association rate constant) was 6.16 x 10-3 dt-1 for the control group, whereas for the intervention group k1 = 26.20 x 10-3 dt-1 and k2 = 16.75 x 10-3 dt-1. Thermodynamically, the overall reaction was endergonic and endothermic (ΔG > 0 and ΔH > 0). CONCLUSIONS Lead exposure results in increased dissociation rate of bone in comparison with its association rate. Overall, the reaction was endergonic and endothermic (ΔG > 0 and ΔH > 0).

Abstract

BACKGROUND Lead accumulation in the blood widely known affecting the formation of heme and oxygen transport processes in vital organs, Leading to organ failure including the brain synapses. Lead affinity has been recognized influenced by constitutional genotype of aminolevulinate dehydrogenase (ALAD), which encodes for heme synthesis. This research aimed to determine the relationship between plumbum (Pb) and short term memory on each ALAD gene genotyping (ALAD 1-1, ALAD 1-2 or ALAD 2-2) in gas station workers. METHODS Seventy six probands from gas station workers were recruited to participate in this research. Each probands was carried out ALAD genotyping using polymerase chain reaction-restriction fragment length polymorphism (PCRRFLP) method, lead serum level using atomic absorbent spectrophotometer (AAS), and short term memory was measurement by intelligence structure test (IST). RESULTS Proportion of δ ALAD 1-1, 1-2, and 2-2 were 91.8%, 8.2% and 0% respectively. Lead serum showed 15.84 ppb in homozygous 1-1, and 20.79 ppb in heterozygous. Short term memory in the probands varied from 85 until 117, with average in 99.71. There was significant negative relationship between lead serum and short term memory (r=-0.24; p=0.038). However, we could not find any significant correlation in each δ ALAD genotypes. CONCLUSION The δ ALAD genotypes did not modified the relationship between serum lead level and short term memory in gas station workers.

Abstract

BACKGROUND Urinary tract infection (UTI) is a common source of bacteriemia. The most common cause of UTI is Escherichia coli (E. coli). Tumor Necrosis Factor (TNF)-á gene polymorphism has been reported to be responsible for an excessive production of TNF-á and eventual disruption of pro-inflammatory cytokine regulation. The aim of this study was to compare TNF-á serum levels and TNF-á allele polymorphisms in patients with UTI due to E.coli and in non- UTI controls. METHODS A cross-sectional study was conducted at Dr. Kariadi Central Hospital and the Center for Biomedical Research, Faculty of Medicine, Diponegoro University, Semarang. In 68 patients with UTI the TNF-á serum levels were determined by means of ELISA and compared to those of non-UTI controls (n=55). TNFá- 308G>A gene polymorphism was analyzed by polymerase chain reaction restriction fragment length using the NcoI enzyme. Fragments were visualized on polyacrylamide gel with silver staining. RESULTS TNF-á serum level in patients with UTI had a median of 8.9 pg/mL, which was significantly higher than the median of 3.7 pg/mL in the control group (pA gene polymorphisms found in the patient group were G/G=61 (90%), G/A=7(10%) and A/A=0, while in the control group were G/G=48 (87%), G/A=7 (13%) and A/A =0. There was no significant differences (p=0.578) in gene polymorphisms between the two groups. CONCLUSIONS TNF-á serum levels in patients with UTI due to E. coli were significantly higher than in non-UTI controls, but for the TNF-á-380 gene polymorphisms no significant difference was found between the two groups. There are presumably more important factors than host genotype that influence UTI pathogenesis.

Abstract

BACKGROUND Physical activity is the greatest contributor to achievement of adequate physical activity. Children performing adequate daily physical activity will get positive benefits from their activity. Several studies indicate a difference in motor skills between boys and girls. To understand the development of motor skill proficiency and physical activity in boys and girls, a study was conducted to determine the role of gender on motor skill proficiency and physical activity in children aged 6-12 years. METHODS A cross-sectional observational study was conducted and a total of 162 children were included at a primary school in the Grogol area, West Jakarta. Data collection was by questionnaire-based interviews, covering age, gender, and physical activity (watching TV, playing games, and outdoor play). Assessment of motor skills was performed using the Bruininks-Oseretsky Test–Second Edition (BOT-2). Data analysis was performed using SPSS for Windows release 17.0 and level of significance was set at 0.05. RESULTS Multiple linear regression results showed that in boys the strength subset was the most influential factor on TV watching activity, with the higher scores for strength indicating a lower TV watching activity (â=-0.125;p=0.021). Age was the most influential factor on outdoor playing activity in girls, with older girls having lower outdoor playing activity (â=-0.375;p=0.016). CONCLUSIONS This study revealed that gender difference impacts on motor skills and physical activity in children. Higher motor proficiency increases outdoor playing activity only in boys. Primary school pupils should be given opportunities for performing outdoor playing activities to improve their motor proficiency.

Abstract

BACKGROUND Cell surface mucin glycoproteins are expressed on the mucosal surface. One of these cell surface mucins is mucin-1 (MUC1), which plays a role as a physical barrier and limits inflammation. However, its functional role in modulating responses to pathogens, particularly with respect to intracellular signaling, needs to be investigated. Therefore, the aim of this study was to characterize the modulation of responses of human gastric epithelial cells by MUC1 to common mucosal pathogens and inflammatory stimuli. METHODS Human gastric epithelial cell lines (MKN7) were co-cultured with Campylobacter jejuni (C. jejuni). In order to investigate the effect of MUC1 expression on C. jejuni-induced cytokine production, MKN7 cells were transfected with 1:1 small interfering RNA (siRNA) to knock down the MUC1 gene using MUC1 targeting siRNA or non targeting siRNA as a control. The read out of the experiment was interleukin (IL)-8 concentration as a result of the inflammation process. This cytokine concentration was measured using ELISA and compared between the two groups. RESULTS This study demonstrated that by using siRNA transfection, knockdown of MUC1 expression in MKN7 human gastric epithelial cells suppressed IL-8 production at the early phase of incubation, but promoted an increase in IL-8 production at the late phase, in response to C. jejuni. CONCLUSION Knockdown of the MUC1 gene in MKN7 cells reduced IL-8 levels both in the cells with and without exposure to C. jejuni. This study provides direction for exploration of the intracelular mechanisms by which cell surface mucins modulates inflammation in the response of gastrointestinal epithelial cells to pathogens or other inflammatory stimuli.
