Abstract

IntroductionThe elderly have a greater risk of zinc deficiency compared to younger adults. This condition may be reflected by a lowered zinc intake and reduced zinc absorption in the elderly. The aim of the study was to explore the dietary zinc intake and zinc status differences between male and female elderly.MethodsA cross-sectional study was conducted included eighty-nine free-living subjects, aged above 60 years, apparently healthy and ambulatory. A two day and non consecutive diet record was used to assess energy and nutrient intake of the elderly. It was combined with a semi-quantitative food frequency questionnaire (SQ-FFQ), with food model that was also used to quantify the food pattern on each food frequency item. Serum zinc concentrations were measured by using atomic absorption spectrum photometry. ResultsThe total energy intake and normal serum zinc concentration in both genders of free-living elderly were mostly below the recommended dietary allowance. The mean serum zinc concentration did not differ significantly between female (13.7 µmo/l) and male elderly (13.9 µmo/l). Mostly the intake of zinc was below two thirds of the RDA it presented on intake of zinc in males was much less compared to female. Overall, the prevalence of zinc deficiency appeared low among the free-living elderly in South Jakarta.ConclusionsThe prevalence of zinc deficiency was relatively low in healthy elderly. Prevalence of zinc deficiency and zinc intake were lower in female compared to male elderly.

Abstract

Blood transfusion is a long-known life-saving procedure for patients in need of blood, as its history can be traced to about 200 years ago. The first successful blood transfusion performed from one human to another was pioneered by James Blundell, an obstetrician who in 1818 succeeded in transfusing 227 mL of blood to a patient with postpartum hemorrhage

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

BackgroundSmoking is the act of introducing toxic substances into the body. Cigarette smoke contains chemicals that may cause several disorders, including cardiovascular disease, cancer, and chronic obstructive pulmonary disease. Toxic substances in cigarette smoke have the potential to increase free radicals, malondialdehyde (MDA) levels and to decrease endogenous antioxidant (glutathione/GSH) levels. This study aims to determine the relationship of smoking with plasma GSH and MDA levels in medical students.MethodsThis study was analytical observational with cross-sectional approach. The study was conducted from April to December 2015. The subjects in this study were medical students, consisting of 20 smokers and 20 nonsmokers. Plasma GSH and MDA levels were determined biochemically using Sigma GSH Assay Kit and Sigma MDA Assay Kit. Data was analyzed using the independent t test. ResultsThe results showed that there was no significant difference between mean GSH in smokers (1.74 ± 0.91 mmol/L) and nonsmokers (2.42 ± 1.19 µmol/L) (p=0.441). Mean smokers MDA level of 2.06 ± 1.39 nmol/mL was not significantly different compared with mean nonsmokers MDA level (1.32 ± 0.90 nmol/mL) (p=0.092).ConclusionsSmoking tends to decrease plasma GSH levels and increase plasma MDA levels in medical students. Smoking history could be evidence of oxidative stress and an impaired oxidant defense system. In particular, young smokers should quit promptly before health problems arise, so as to have the optimal benefits of cessation.

Abstract

Increased irrational use of antibiotics promotes bacterial resistance to these drugs. Among the resistance mechanisms developed by bacteria is the production of â-lactamase which can destroy the â-lactam ring and cause resistance to the other â-lactam antibiotics, such as amoxycillin. Extended spectrum â-lactamase (ESBL), an enzyme found in bacterial plasmids, is capable of hydrolyzing third-generation cephalosporins, namely cefotaxime, ceftazidime, ceftriaxone, and the monobactams. ESBL is predominantly found in Klebsiellas spp., Escherichia coli and other bacteria of the Enterobacteriaceae family. This study was conducted to determine the prevalence of Klebsiella resistant to cephalosporins and the prevalence of those producing ESBL. A total of 65 clinical isolates of Klebsiella were tested by the disk diffusion method according to Kirby-Bauer to determine their antibiotic susceptiblity and by the double-disk synergy method to detect the presence of ESBL. The results show that 18.5% of Klebsiella isolates tested were resistant to ceftazidime and cefixime, 13.9% to ceftriaxone, and 23.1% to aztreonam. Testing for ESBL revealed that the prevalence of ESBL producers in clinical Klebsiella isolates ranged from 10.8% to 12.3%. The presence of ESBL, plus the potential for plasmid-mediated quinolone and carbapenem resistance, undoubtedly will create significant therapeutic problems in the future.

Abstract

Microbiological procedures for V. cholerae isolation from clinical specimens are important factors in clinical and epidemiological management of cholera. The standard preservation medium for enteric pathogenic bacteria, including V. cholerae, is Cary-Blair medium (CB), a semisolid medium for preservation and transport of specimens containing intestinal bacteria. A special medium for Vibrio organisms is alkaline peptone water (APW), which is both a transport and an enrichment medium. The purpose of this study was to ascertain the suitability of APW supplemented with 0.5% agar (APW-0.5) as a sensititive preservation-transport medium for rectal swab specimens for isolation of V. cholerae. A total of 144 paired rectal swab specimens were collected from children and adults with acute diarrhea. Of each specimen pair, one was placed in CB and the other in APW-0.5, from which they were plated out to thiosulfate citrate bile sucrose (TCBS) agar. Altogether, from both CB and APW-0.5 transported specimens, V. cholerae non-O1 was present in 29 (20.1%) specimens, while only 2 (1.4%) specimens were positive in CB and 9 (6.3%) positive in APW-0.5 transported specimens. The number of V. cholerae non-O1 isolates from APW-0.5 transported specimens was significantly higher (p=0.000) as compared to that from Cary-Blair transported specimens. It may be concluded that for isolation of V. cholerae, specimen transport in APW-0.5 medium was more effective than transport in Cary-Blair medium.

Abstract

BACKGROUNDMany tumors express on their receptor tyrosine kinases vascular endothelialgrowth factor activity associated with angiogenesis. Inhibition ofangiogenesis through reduction of tyrosine kinase activity is a promisingstrategy for cancer therapy. The present study aimed to determine themechanism and potency of ethyl p-methoxycinnamate (EPMC) isolatedfrom Kaempferia galanga as angiogenesis inhibitor.METHODSA laboratory experimental study was conducted using chorio-allantoicmembranes (CAMs) of nine-day old chicken eggs induced by 60ng basicfibroblast growth factor (bFGF). Ethyl p-methoxycinnamate (EPMC) potencywas determined at dosages of 30, 60, 90 and 120 μg and compared withcelecoxib 60 μg as reference drug and one negative bFGF-induced controlgroup. Neovascularization and endothelial cell count in CAM blood vesselswere evaluated. To predict the antiangiogenic mechanism of EPMC, adocking study was performed with the Molegro Virtual Docker program ontyrosine kinase as receptor (PDB 1XKK).RESULTSAngiogenesis stimulation by bFGF was prevented significantly (p<0.05)by EPMC at dosages of 30, 60, 90 and 120 μg and this activity was dosedependent. Molecular docking showed interaction between EPMC functionalgroups and tyrosine kinase amino acids at Met766, Met793, Thr854, Thr790,Gln791 and Ala743. There was an association between EPMCantiangiogenic activity and docking study results.CONCLUSIONSEthyl p-methoxycinnamate is a potential new angiogenesis inhibitor throughinteraction with tyrosine kinase. EPMC could be a promising therapeuticagent for treatment of angiogenesis-related diseases.

Abstract

Migraine is one of the most prevalent disorders seen in clinical practice today and also a major cause of disability in the workplace. The prevalence of migraine is highest during the years of peak productivity, ie, between the ages of 25 and 55 years. The triptans are a group of selective 5-hydroxtriptamine (HT)1 serotonin receptor agonists that activate the 5-HT1B/1D receptor and possibly also the 5-HT1A dan 5-HT1F receptors. To date 7 subclasses of serotonin receptors have been identified, namely subclasses 5-HT1 to 5-HT7. Triptan causes cranial vasoconstriction, inhibits peripheral trigeminal activity and the trigeminal afferents. With its triple action, triptans can control acute attacks of migraine. Triptan is contraindicated in patients with previous ischemic or coronary artery disease, cerebral or peripheral vascular disease and other cardiovascular disorders. Triptans should be given immediately after an acute attack of migraine. The triptans are useful in the management of an acute migraine, but are not indicated for preventive therapy of migraine. Several new advances in migraine management have been made in regard to the recognition of the disease, the pathogenesis of migraine, and the phenomenon of central sensitization. More treatment options become available to patients and prescribers, the impact of such therapy on worker productivity will become more important in determining the value of such interventions.

Abstract

BackgroundThe acute gastroenteritis caused by campylobacteriosis is known as one of the common infectious diseases with worldwide distribution. The aim of this study was to detect Campylobacter species in stool samples by routine culturing and polymerase chain reaction (PCR) and explore the risk factors in adult subjects in East Azerbaijan province of Iran.MethodsA cross sectional study involving 1010 adult subjects, from whom stool samples were collected. Samples with inflammatory criteria like fecal leukocytes (WBC ³5) were selected and isolated through fecal lactoferrin detection test. The WBC ³5 and lactoferrin positive samples were selected for Campylobacter detection by culture and PCR methods. The required information consisting of gender, age, place of habitation, and contact with poultry and animals were asked and recorded. Chi-square test and prevalence ratio (PR) was used to analyze the data.ResultsOf 1010 stool samples, 231 (22.9 %) had WBC ³5, and from these samples 58 (25.1%) were positive by culturing and 61 (26.4 %) by PCR. Subjects having habitual contact with animals and poultry had increased risk of Campylobacter infections by 1.65 times compared with subjects without contact with animals and poultry (PR=1.65; 95% CI:1.07-2.68).ConclusionsDetection of Campylobacter infections by PCR was more sensitive in adults. Investigation of Campylobacter prevalence in Ardabil showed this bacterium should be viewed as one of the possible pathogens in inflammatory diarrheal cases. People having habitual contact with animals should check the health of the animals regularly and not consume food from suspected sources.

Abstract

Chikungunya (CHIK) adalah penyakit yang disebabkan oleh virus dari genus Alphavirus, famili Togaviridae, dan ditularkan melalui gigitan nyamuk Aedes aegypti dan Ae. albopictus yang terinfeksi oleh virus tersebut. Penyakit ini pertama kalinya dilaporkan oleh Robinson dan Lumsden setelah terjadinya wabah di lembah Makonde tahun 1952. Seperti halnya dengan malaria dan dengue, penyakit ini telah menjadi endemis di negara-negara di Afrika dan Asia. dan telah menimbulkan wabah di tempat-tempat tersebut. CHIK ditandai oleh adanya tiga gejala khas (trias) yaitu demam, nyeri sendi (arthralgia) dan ruam kulit (rash). CHIK adalah penyakit yang bersifat dapat sembuh sendiri (self-limiting) dan tidak ada pengobatan yang spesifik untuk demam CHIK. Upaya pengobatan hanya bersifat simtomatis, oleh karena itu pengendalian vektor merupakan usaha yang tepat pada pencegahan penyakit.
