Endothelial dysfunction in diabetes mellitus
Diabetes mellitus is associated with an increased risk of cardiovascular disease, even in the presence of intensive glycemic control. Substantial clinical and experimental evidence suggest that both diabetes and insulin resistance cause a combination of endothelial dysfunctions, which may diminish the anti-atherogenic role of the vascular endothelium. Both insulin resistance and endothelial dysfunction appear to precede the development of overt hyperglycemia in patients with type 2 diabetes. Therefore, in patients with diabetes or insulin resistance, endothelial dysfunction may be a critical early target for preventing atherosclerosis and cardiovascular disease. Microalbuminuria is now considered to be an atherosclerotic risk factor and predicts future cardiovascular disease risk in diabetic patients, in elderly patients, as well as in the general population. It has been implicated as an independent risk factor for cardiovascular disease and premature cardiovascular mortality for patients with type 1 and type 2 diabetes mellitus, as well as for patients with essential hypertension. A complete biochemical understanding of the mechanisms by which hyperglycemia causes vascular functional and structural changes associated with the diabetic milieu still eludes us. In recent years, the numerous biochemical and metabolic pathways postulated to have a causal role in the pathogenesis of diabetic vascular disease have been distilled into several unifying hypotheses. The role of chronic hyperglycemia in the development of diabetic microvascular complications and in neuropathy has been clearly established. However, the biochemical or cellular links between elevated blood glucose levels, and the vascular lesions remain incompletely understood. A number of trials have demonstrated that statins therapy as well as angiotensin converting enzyme inhibitors is associated with improvements in endothelial function in diabetes. Although antioxidants provide short-term improvement of endothelial function in humans, all studies of the effectiveness of preventive antioxidant therapy have been disappointing. Control of hyperglycemia thus remains the best way to improve endothelial function and to prevent atherosclerosis and other cardiovascular complications of diabetes. In the present review we provide the up to date details on this subject
Inflammatory cytokines and atrial fibrillation: current and prospective views
Atrial fibrillation (AF) is the most common sustained arrhythmia and a challenging clinical problem encountered in daily clinical practice. There is an increasing body of evidence linking inflammation to a broad spectrum of cardiovascular conditions including AF. Historical evidence supports an association between AF and inflammation and is consistent with the association of AF with inflammatory conditions of the heart, such as myocarditis and pericarditis. AF has been associated with myocardial oxidative stress, and antioxidant agents have demonstrated antiarrhythmic benefit in humans. Increased plasma interleukin (IL)-6, C-reactive protein (CRP), and plasma viscosity support the existence of an inflammatory state among “typical” populations with chronic AF. These indexes of inflammation are related to the prothrombotic state and may be linked to the clinical characteristics of the patients (underlying vascular disease and comorbidities), rather than simply to the presence of AF itself. It has been suggested that inflammation may have a role in the development of atrial arrhythmias after cardiac surgery, and that a genetic predisposition to develop postoperative complications exists. Cytokines can have a prognostic significance; IL-6 levels, CRP, and other cytokines may have prognostic value in AF. Cytokine lowering therapies, statins, angiotensin converting enzyme inhibitors and other anti-inflammatory agents may have a role in the treatment of AF. The present article provides an overview of the evidence linking inflammatory cytokines to AF and their therapeutic and prognostic implications
Gambaran Kebiasaan Minum Air Putih pada Ibu Hamil dan Ibu Menyusui di Poli BKIA RS Bhakti Rahayu
Poor fluid intake can cause either mild or chronic hypovolemia for pregnant
mothers. This will certainly complicate the delivery process. On the other hand,
for breastfeeding-mothers, in addition to normal fluid loss through urination,
evaporation (sweat), and defecation (stool), mothers also loss a lot of water from
breastfeed. Consequently, hydration has become essential for both pregnant and
breastfeeding mothers. There are many types of fluids that can be consumed by
pregnant and breastfeeding mother. Water has the most dominant contribution in
hydration process compared to other types of liquids. However, preliminary
studies among the majority of pregnant and breastfeefing mothers shows that they
have a habit of consuming lesser water, due to myths. Taking this further, this
study aims to see a general picture of water consumption among pregnant and
breastfeeding mothers.
This research uses quantitative approach and descriptive method with
qualitative method (in depth interview) as complemented data. This study takes
the sample of pregnant women and breastfeeding mothers in RS Bhakti Rahayu
Surabaya with total of 50 mothers, 25 mothers each. The sampling technique used
is simple random sampling.
The result shows that both pregnant and breastfeeding mothers have a
good water consumption habit, although there are still few, who have poor level
of water consumption habit.This may be due to high levels of exposure to external
information, particularly health, given that the majority of mothers are active
social media users and often use the platform as an information portal

Elevated serum leptin levels in patients with acute myocardial infarction; correlation with coronary angiographic and echocardiographic findings
BACKGROUND: To assess the relationship between serial serum leptin levels in patients with acute myocardial infarction (AMI) who received thrombolysis and the degree of coronary atherosclerosis, coronary reperfusion, echocardiographic findings, and clinical outcome. 51 consecutive patients presenting with AMI were studied. Clinical characteristics including age, sex, body mass index (BMI) and cardiovascular risk factors were recorded. Serial serum leptin levels at the time of admission and subsequently at 0, 6, 12, 24, 36, 60 hours afterwards were obtained. Coronary angiography was performed in 34 patients; the relation between serum leptin levels and evidence of coronary reperfusion as well as the extent of coronary atherosclerosis according to the coronary artery surgery study classification (CASS) were evaluated. Echocardiographic evaluation was performed in all patients. 36 matched patients were enrolled as control group who had serum leptin level 9.4 ± 6.5 ng/ml. RESULTS: The patients mean age was 50.5 ± 10.6 years. There were 47 males and 3 females. 37.1% were diabetics, 23.5% were hypertensive, 21.6% were dyslipidemic and 22.7% were obese (BMI ≥ 30). Leptin concentrations (ng/ml) increased and peaked at the 4th sample (36 hrs) after admission (mean ± SD) sample (1) =9.55 ± 7.4, sample (2) =12.9 ± 8.4, sample (3) =13.8 ± 10.4, sample (4) =18.9 ± 18.1, sample (5) =11.4 ± 6.5, sample (6) =10.8 ± 8.9 ng/ml. There was a significant correlation between serum leptin and BMI (r = 0.342; p = 0.03). Leptin levels correlated significantly to creatine kinase level on the second day (r = 0.43, p ≤ 0.01). Significant correlation of mean serum leptin with the ejection fraction (P < 0.05) was found. No difference in timing of peak serum leptin between patients who achieved coronary reperfusion vs. those who did not (p = 0.8). There was a trend for an increase in the mean serum leptin levels with increasing number of diseased vessels. There was no correlation between serum leptin levels and outcome neither during the hospitalization nor at 9 months follow up. CONCLUSION: Serum leptin levels increase after myocardial infarction. Serum leptin level may be a predictor of the left ventricular ejection fraction and the degree of atherosclerosis but not of coronary reperfusion

Economics bridge between theory and practice of Sustainable built environment: a case for marginal benefit and marginal cost
Common economic gauges that validate Sustainable Built Environment
(SBE) in households may cause for such projects to be shelved especially when the
result of commercial feasibility study does not favour the stakeholders. It is a fact that
the capital cost of Energy Efficient (EE) equipment and Renewable Energy (RE) system
are more expensive than the conventional methods. However, SBE is now necessary
and the gap between theory and practical of SBE in relation to economics aspect must
be narrowed. The economics of SBE must not only assert the environmental implication
but also make tangible its benefit to the household for championing the cause. In
Economics, Marginal Cost (MC) and Marginal Benefits (MB) measure additional benefits
of every additional costs of investment at a specific level of production and consumption;
and Economists suggests that effective gain and loss must be compared to the status
quo, i.e., Relative Position (RP). These Economics theories of MC, MB and RP are
adapted to measure the progression of SBE with regards to lighting requirements in a
living/dining area simulated to represent two types of houses: with and without Passive
Architecture (PA) design strategies. Both are applied with conventional incandescent
light bulbs and EE light fittings as well as RE in lieu of the mains electricity supply. The
comparative approach shows the value of MB and MC at every stage of the SBE
progression and this enables the household to make informed decision at a margin. The
result suggests that the value of MB is more than MC when both cases use EE light
fittings, i.e., approximately RM2 gain for every RM1 cost. It is also found that RE
benefits the household more in PA case. This approach makes economic sense in so
far encouraging household to opt for SBE
