Abalone has an economic value in the world. The larval rearing technique of abalone has produced successfully at Gondol Research and Development Institute for Mariculture, Bali, Indonesia. However, the grow-out of abalone has not well documented yet. The purpose of this experiment is to examine the shelter shape in relation to growth and survival for abalone (Haliotis squamata) grow-out culture in the tidal area. The shelter made from PVC piping. The shape of shelter as a treatment of this experiment was A) round; B) square and; C) without shelter. The data of growth and survival rate were analyzed using analysis of variance. The result showed that the shelter for the grow-out of abalone was significantly affected growth in terms of shell length and wet weight (P<0.05) while the survival did not influence (P>0.05). It seems that the shelter was correlated with the feeding behavior of abalone had resulted in different for their growing. The water quality such as salinity, dissolved oxygen, water temperature, and water current was within the optimal range for abalone. We found that round shelter shape is the best for grow-out abalone at the tidal area.

The quality and quantity of Moina ephippia is influenced by the male and female sexual ratios in the population. The availability of males in the population can increase the number of fertilized eggs and ephippia hatching rates. This study aims to examine the concentration of rice bran suspension in culture to produce the most male offspring, and the quality and quantity of ephippia produced. Moina was cultured for twelve days and from the fifth day the feed is given with different concentrations. The results of this study indicate that, Moina culture using bran suspension feed with a concentration of 0.36-0.48 ml/L starting on the fifth day resulted in the production of low calf offspring but produced the highest total production of male offspring of 818±35 ind/L. Increased production of male offspring increases the production of ephippia containing two eggs but does not increase the degree of hatching significantly.

The purpose of this research is having experience from around the world shows that fisheries management that produces lasting economic and ecological performance requires the use of fishing rights (rights-based fisheries management/RBFM) integrated as part of a well-designed management system that includes sustainable catch limits and effective monitoring and enforcement. The concept of fishing rights is not a new thing in Indonesia – in fact, many adat (traditional) customs such as sasi, awig-awig, and penglima laut are consistent with fishing rights and have been recognized for centuries. Such customary systems can provide a foundation for a new and effective system of fishing rights specially tailored to the culture, customs and needs of Indonesia. This research is using a qualitative method to identify what exactly happened in a coastal zone area. In reality, the concept of the Right to Management of Coastal Communities in the Regional Autonomy era has never been implemented in regional regulations that explicitly consider the rights needs of local communities. From the case of processing sea cucumber management permits in Sunsak Bay, East Lombok, it shows that local communities have never been a priority in the regional regulations to obtain the right to manage sea cucumbers.

Tilapia (Oreochromis niloticus) is a freshwater aquaculture commodity with high demand and economic value. With developing breeding technology, hybrid tilapia also grows in popularity. Pandu tilapia is a strain of Singapore tilapia, while Kunti tilapia is a GIFT (Genetically Improved Farmed Tilapia) strain. To ensure the continuity of good fingerling stock, the individual selection needs to be conducted on Pandu and Kunti Tilapia broodstock candidates. The family selection method was chosen using 125 pairs of broodstock candidates. The male and female ratio is 1: 1 with horizontal breeding where a broodstock was mated with another fish from its own family or strain to ascertain that there is no cross-breeding. Larvae hatched from the spawning were reared in a nursery pond, then graded. The top 50% fish was reared until reaching the adult stage and bred again. The broodstock candidates were then tested for its performance and mass spawned.

Milkfish cultivation has long been recognized by farmers and is now developing in almost all Indonesian waters. Fish culture technology is also experiencing rapid development, ranging from traditional maintenance to intensive technology that requires seed, water, and planned feed management. One way to fill the empty ecological space is to cultivate a mixture (polyculture) between several fisheries commodities. With this system, the benefits obtained are high land productivity. The development of aquaculture technology shows that milkfish (Chanos chanos Forskal) can be cultivated together with Gracilaria sp. Seaweed in a pond. This polyculture system can increase the efficiency of land use and farmers' income in a sustainable manner. The study was conducted using the experimental method. The density of gracilaria sp distribution in this study was: treatment A (nongracilaria), treatment B (gracilaria 50 Kg), treatment C (gracilaria 100 Kg), treatment D (gracilaria 150 Kg) and Treatment E (gracilaria 200 Kg). The design used was a completely randomized design (CRD) with 5 treatments and 3 replications. The main parameters observed were growth including absolute length, absolute weight, specific growth rate, and survival. As supporting data the measurement of water quality is also carried out.

This study seeks to determine the best method for preventing separating one cell into two cells in early embryogenesis as a means to induce tetraploid in the Mutiara catfish strain (Clarias sp.). Heat shocks were applied to newly fertilized eggs. Heat shock that was administered at 40 °C, for 4 min at 30 min post-spawning, was the best method for tetraploid induction, as evidenced by the highest percentage of forming four pronuclei in syngamy (84.12%). Therefore, heat shock induction was employed to further explore the advantage of tetraploid over diploid catfish. After hatching of the heat-shocked eggs, the larvae were allowed to reach juvenile levels of development. At day 30 in culture, the number and amount of chromosomes were determined in juvenile stages, using Silver Nitrate Staining methods, by which the catfish were divided into diploid and tetraploid groups. The average specific growth rate of the tetraploid (22.55%/gr/day) was significantly higher (Pb 0.05) than that of their diploid counterparts (15.42%/gr/day). These results reveal the advantages of growing tetraploid over diploid Mutiara catfish strain and its feasibility for future commercial production.

In situ data of Longtail tuna fishing location and satellite-based oceanographic data of chlorophyll-a concentration (chl-a), sea-surface temperature (SST), and salinity were employed to figure out the impacts of oceanographic condition on the pattern of potential fishing zones for Longtail tuna in waters around Madura Island. The relation of those parameters to the dissemination of Longtail tuna was analyzed with a maximum entropy (Maxent). The predictive model performance was estimated using the area under the curve (AUC). The jackknife test was then employed to examine each parameter's model contribution. The results from the Maxent model exhibited a high predictive success of the model with AUC value of 0.932. Maxent prediction showed a high probability occurrence of Longtail tuna occurred in the offshore area of the Java Sea. The results also revealed that the Longtail tuna habitat selection was significantly controlled by the salinity ranges from 32.3 – 32.5 ppt, SST ranges from 29.5–30.5°C, and chl-a ranges from 0.2 – 0.4 mg/m3. Besides, among the set of oceanographic variables utilized (SST and chl-a), salinity exhibited the highest value of the jackknife test. Therefore salinity expressed to be the most significant factor in the geographic dissemination of Longtail tuna in the waters Madura Island.

Acute hepatopancreatic necrosis disease has been a major challenge faced by white shrimp farmers in many shrimp-producing countries inducing Indonesia. The etiological agent of this disease was a virulent strain of Vibrio parahaemolyticus. However, a technology to treat or to prevent the disease infection has not been established yet, and probiont could be a potential approach for this disease. Thus, this study aimed at screening 35 lactic acid bacteria (LAB) that originated from the gastrointestinal tract of wild white shrimp for the production of antivibrio compounds using an agar well diffusion. The result showed that three LAB strains (LAB-1, LAB-2, and LAB-3) showed antivibrio activity indicated by the formation of clearance zone (diameter of >10mm) on the diffusion agar plate. When the extracellular products (ECP) were incubated with proteinase K, the antivibrio activity was disappeared which indicated that the antimicrobial compounds were bacteriocin-like inhibitory substances (BLIS). Phenotypic studies suggest that the LAB were Labctobacillus sp. (LAB-1 and LAB-2), and Enterococcus sp. (LB-3). These results suggest these LAB are potential candidates for preventing V. parahaemolyticus. Infection, although, further assays by in vivo using live white shrimp, are still required.

Indonesia is part of the coral triangle region which is known as the world's highest marine biodiversity, including stony corals. This situation used to benefit local people by trading ornamental corals. The aims of this study are to investigate the potential stock of ornamental corals as well as the reef conditions. The study took place in Kendari, Luwuk, Sumbawa and Belitung where the ornamental coral-collecting activities used to occur. The result indicates there were approximately 110 species of corals found with the majority of coral status are common (harvest limited) and uncommon (harvest with cautions). Based on the juvenile existence, only 66 corals have potential stocks. Euphyllidae (Euphyllia glabrescens and Plerogyra sinousa) had the highest potential stock in Kendari and Luwuk, while Fungiidae (Fungia spp) held the highest potential stock in Belitung and Sumbawa. This difference is likely related to different locality or habitat type. In general, coral reefs in Kendari, Luwuk and Belitung are in good condition, while fair condition occurs in Sumbawa. To conclude, the stock of ornamental corals is still high and the reefs are generally good, suggesting the collecting activities may be allowed with proper quota and continuous monitoring habitat condition to ensure the sustainability.

Indonesia exported >900 species of marine ornamental organisms, considered the largest together with The Philippines. However, records on catch statistics are negligible — this study conducted along the coastal area of Bangsring (Banyuwangi) and Gerokgak (Bali). The research aimed to identify species diversity, dominant families, and catch composition. Species diversity was estimated through underwater visual census and catch records from three fish collectors in the area. All the species were photographed and deposited at Depository Ichthyologicum Brawijaya, each with a specific accession number. Species identification merely based on morphology and color-stained for transparent osteology. The results of the analysis showed that there at least 106 species out of 483 specimens collected from middlemen. It consisted of 25 families and 59 different genera. The fish sources came from local surrounding West Bali National Park (Pinggiran), Madura Islands (Bunian), and the eastern part of Indonesia (Tanjungan). Unit price at middlemen levels varied between US$ 0.2-3.6 per species, with an average of US$ 0.95±0.95 (n = 106). Three Tanjungan species: Hoplolatilus luteus, Pomacanthus imperator, and Paracanthurus hepatus sold at unit price US$ 8.5. This niche fishery needs specific management measures to control the supply chain apart from its economic contribution to national income.

Probiotic is considered an effective means for disease prevention in the aquaculture system. The most of probiotic species used in aquaculture were Bacillus in the form of vegetative cells. Therefore, this study evaluates the immune responses of Oreochromis niloticus under the Bacillus supplementation in the form of vegetative cells and spore. The addition of vegetative cells and spore Bacillus was given in the fish diet for 49 days. Several non-specific immune responses were evaluated afterward. Treatment without Bacillus supplementation in the diet was used as a control. The results showed that Bacillus supplementation in the form of spore and vegetative increased the non-specific immune response compared to those of control. Some parameters of the immune response, such as total leukocytes, haematocrit value, and respiratory burst, were affected by the form of Bacillus supplementation. Total haematocrit (31.67%), total leukocytes (8,2x104 cells.mm-3), Lymphocyte (81.33%) and respiratory burst (0.09 nm) of Tilapia with spore Bacillus supplementation were noted as the highest value. On the other hand, the phagocytosis activity of Tilapia was found statistically similar to vegetative or spore form of Bacillus supplementation. The factor that affected those results was the higher viability of the Bacillus spore in the fish diet. This study indicated that Bacillus supplementation in the form of spore gave the best improvement on the Tilapia non-specific immune response and could maintain the health status of the fish.

Catfish cultivation has been carried out in Indonesia. One such development is the maintenance of catfish using an aquaponic system. Aquaponics aims to improve the water quality of fish farming with the help of plants. But plants cannot directly utilize fish farming waste directly, it is necessary to have a nitrification process first. Nitrification is the reformation of inorganic compounds into organic compounds with the help of bacteria. Nitrifying bacteria are colonized and non-motile bacteria, so a substrate is needed as a place to attach to the bacteria. The substrate that can be used is bioball and bioring. This study aims to determine whether the effect and filter media are effective in catfish farming with an aquaponic system. This study using the RAL method consisting of 4 treatments and 5 replications, namely P0 = control, P1 = bioball, P2 = bioring and P3 = bioball and bioring combinations. The results obtained that P3 (bioball and bioring combination) is the most effective treatment in reducing the nitrogenous waste catfish aquaculture using an aquaponics system, the results is 0,000 mg / L ammonium, nitrite 0.001 mg / L and nitrate 13.0 mg / L at the end of the study.

Recirculating aquaculture system (RAS) and active suspension aquaculture system (ASS) are rearing systems which are commonly used in aquaculture productions nowadays. This study aimed at comparing the growth performances of Nile tilapia cultured at the two aquaculture systems for 42 days. The measured parameters were growth rate, weight gain, feed conversion ratio, survival rate, and nutrient utilization (protein efficiency ratio, fat efficiency ratio, and energy efficiency ratio). The results showed that Tilapia reared in the RAS had significantly higher growth rate, weight gain, lower feed conversion ratio, and more efficiently in the utilization of protein, fat, and energy compared to tilapia reared in ASS. These results may indicate that the recirculating aquaculture system provided more comfortable environments for the tilapia for growth compared to the active suspension aquaculture system. However, another study in terms of economic perspective is still required, since the recirculating aquaculture system requires more rearing tanks and operational costs, especially from electricity.

Fishery-based lobster production decreased substantially due to over-exploitation and urge fishermen to catch smaller-size. In early 2015, the Ministry of Marine Affairs and Fisheries restrained catch of species up to 8 cm carapace length or at least 200 g weight. This study to identify species and individual size within catch of two different fishing gears at different fishing ground. "Krendet", demersal pot (trap) was operated from the cliff of strong reef crest that connected to land-coast with a strong rope. Outside the cliff, fishermen operated gill net. Catch species were identified based on morphology and meristic. Species composition was calculated based on number of each species within catch. The results showed that there were six species was catch: Panulirus penicillatus, P. homarus, P. longipes, P. ornatus, P. versicolor, and P. polyphagus. It represents all lobster species of Indonesia. P. homarus dominated the catch at fishing ground outside the pinnacle (63%), and near cliff species was dominated by P. penicillatus (69%). Regarding size regulation, only 42% of catch met the carapace length of > 8 cm. Carapace length-weight relationship does not always meet the criteria. These results indicated that part of lobster fishery were exploited undersize exposing the stock under risk.

Atherosclerosis is a major cardiovascular issue in the world. Atherosclerosis has long been theorized to be originated from foam cells that build up due to the chronic inflammatory process of cholesterol deposition in the walls of blood vessels and the uptake of oxidized LDL (OxLDL) and phosphorylcholine. Until now, the treatment for atherosclerosis has been focusing on drugs that inhibit the progression of atherosclerotic plaques. Recent findings show that proper regulation of immune cells, both adaptive and innate, has been shown to have a relationship with the prevention of atherosclerotic lesions. The future of vaccination as prevention for atherosclerosis holds great potential, considering studies are abundant in proving the atheroprotective effects of the immunization with several types of antigens. In this literature review, we will discuss the types of antigens which hold promising potentials for atherosclerosis vaccine development and its future challenges.

Coronary heart disease (CHD) causes high mortality and morbidity in many countries. Immature platelet reactivity is one of the major causes of CHD thrombus formation due to its larger size and stronger aggregation properties than normal platelets. Though still controversial, diabetes mellitus (DM), which is one of the CHD risk factors, is mentioned to have a strong association with a high immature platelet level. Since studies on immature platelet in stable CHD are limited, the authors intended to search for the difference between immature platelet level in DM and non-DM patients with stable CHD. This research was an observational analytic study with a cross-sectional design; 31 samples of CHD patients who underwent coronary catheterization were obtained. The characteristics of the data was collected by completing a pre-operation form and the immature platelets were counted using an automated cytometry tool, SYSMEX XE 2100. They were analyzed using Pearson's statistical analysis. There was no significant correlation between the immature platelet levels of DM and non-DM patients with stable CHD (p>0.05). There was a significant positive correlation between HbA1C and the immature platelet level (Immature Platelet Fraction, p <0.05; Immature Platelet Count, p <0.01) in stable CHD patients.

The aim of the study is to analyze the correlation between arterial stiffness and left diastolic ventricle stiffness in hypertensive patients. Carotid and femoral artery stiffness and left ventricle diastolic stiffness were measured using a cardiac ultrasound with hypertension patients (n 47). Subjects with chronic kidney disease, a history of cerebrovascular disease, and coronary artery disease were excluded from the study. Arterial stiffness obtained from the carotis communis artery was significantly correlated to left ventricle diastolic stiffness (r) = 0,38, p <0,01. Arterial stiffness measured from the carotis communis artery had a better correlation with left ventricle diastolic stiffness than arterial stiffness measured from the femoral artery (r) = 0,29; p <0,05.There was no difference in arterial stiffness (mean CAS 3,04±1,6 vs 3,60±1,7; p = 0,271 FAS 2,50±0,95 vs 3,03±1.06; p=0,162) and left ventricle diastolic stiffness (2,25±0,68 vs 2,12±0,6; p=0,52) in controlled vs uncontrolled hypertension in this study. Arterial stiffness is associated with increased left ventricle diastolic stiffness. However, further study is needed to determine the mechanisms.

Hypertension (HTN) is a significant health problem because of the high risk of cardiovascular morbidity and mortality. In rural areas, awareness and health facilities are limited, and report on the prevalence and related risk factors of hypertension is scarce. This study aimed to investigate the prevalence and associated factors of hypertension in the rural population in Indonesia. A community-based cross-sectional study was conducted to adult subjects from a rural population in Jombang, East Java, Indonesia. Data were collected by interviews to obtain socio-demographic characteristic and risk factors. Blood pressure measurements were performed using a mercury sphygmomanometer. We enrolled a total of 121 adult subjects. The prevalence of hypertension was 38.8%. Among hypertensive patients, 83% of them do not seek nor receive any treatment. The prevalent risk factors of hypertension in this study were age more than 40 years old (OR=4.1; 95%CI:1.8-8.9), abdominal obesity (OR=2.7; 95%CI: 1.2-6.01), and smoking (OR=3.2; 95%CI: 1.4-7.1). From our study, the prevalence of hypertension was high in rural adult population, and most of them did not receive treatments. Smoking and abdominal obesity are two risk factors that can be modified as one of the prevention strategies. These phenomena requires the attention of health workers.

Elderly people have a higher risk of deep vein thrombosis (DVT) than younger adults. The causes of this are considered multifactorial, including changes in age-related hemostatic factors, greater comorbid conditions, and the frequency of hospitalizations, although they are not fully understood. Besides, DVT in the elderly can be difficult to recognize because the symptoms can appear atypically. The diagnostic approach of DVT remains the same for all age groups, including pre-test probability, D-dimer measurement, and imaging, although these can be less specific in older age. Antithrombotic agents are the main treatment of DVT. Direct oral anticoagulation (DOAC) provides clinicians with more choices for DVT therapy. However, the anticoagulation of DVT in the elderly must always be done carefully, because old age is also a risk factor for the occurrence of bleeding complications. Identifying bleeding risk factors that can be modified and balancing the risk of thrombosis with bleeding, including the selection and adjustment of anticoagulant doses, are important in considerations of using anticoagulants in the elderly. This narrative review summarizes the literature on the management of DVT in the elderly

The aim of this study is to investigate the effect of black tea administration on serum adiponectin level in male Wistar fed with atherogenic diet (AD). This study was designed as a true experimental design that assigns 20 rats, and divides them into four groups as follows: P1 (AD 3 months); P2, P3, and P4 (3 months AD + black tea extract administration at dosage 0.015gr/day, 0.03gr/day, 0.045gr/day, respectively). Serum adiponectin level was measured using ELISA method. This study demonstrated that there is an elevation trend of adiponectin level as the dose elevated. However, serum adiponectin level in AD-only group (380.6ng/mL) was not significantly different with treatment group (386.93ng/mL, 404.27ng/mL, and 416.6ng/mL in P2, P3, and P4, respectively) (ANOVA, p = 0.352). Furthermore, there was no significant association between the dosage of black tea and adiponectin levels (Pearson correlation test, p = 0.073, r = 0.373). We concluded that black tea extract increased serum adiponectin level insignificantly in atherogenic diet rats.

Necrotizing fasciitis (NF) is a devastating severe infection. NF involving periorbital tissue is rarely found. We reported a 42-year-old woman with eyelid edema surrounded by necrotic tissue and pus production for about a week. LRINEC score was 6. Widespread local excision and debridement were urgently performed. Reconstruction performed two weeks after the onset. The rotational flap is taken from her forehead to prompt good skin remodeling and vascularization. A part of the flap slipped underneath the temporal skin. The flap was perfectly grown, and the eyelid function recovered. NF is a rare severe infection and rarely involves the periorbital area. Early recognition is critical. LRINEC score could be used, and urgent debridement is needed. Late skin flap could be a choice to cover the debrided skin and give a good aesthetic yet functional eyelid.

Rheumatic heart disease remains a major medical problem of children and young adults. Rheumatic heart disease is sequelae of acute rheumatic fever, a bacterial infection Group A beta Hemolitiycus streptococci (GAS) in the pharynx. It is based on genetic predisposition and an autoimmune process causing defect of heart valves, hemodynamic changes, endothelial damage. Further, it is usually illustrated by elevated levels of P selectin. This study was conducted to prove the difference between peripheral P selectin level in multivalve and univalve (mitral stenosis) in rheumatic heart disease. This cross sectional study involving 37 RHD patients consists of 18 univalve (mitral stenosis), 19 multivalve, and 22 healthy controls. P selectin levels were collected through peripheral vein and echocardiography was performed. Peripheral P selectin was significantly higher in univalve and multivalve rheumatic heart disease than normal. Peripheral P selectin in multivalve group was higher than univalve group (2,384ng/mL vs 2,028ng/mL; ρ < 0.05). There was significant difference of peripheral P selectin between multivalve and univalve (mitral stenosis). P selectin potentially has an important role as an indicator of inflammation and progression of valve damage in mitral stenosis, rheumatic heart disease.

Left ventricle (LV) remodeling often occurs after acute myocardial infarction (AMI), and early detection and prompt treatment on this condition may improve prognosis of the patients. Basal soluble ST2 and Global Longitudinal Strain (GLS) 2D-speckle tracking echocardiography can detect early changes before LV remodeling occurs. This is an analytic observational study using one group pre-test and post-test design for correlation. Forty-five patients of AMI during August until December 2015 from ICCU and cardiology ward were analyzed and followed up for 12 weeks. There were 45 subjects with AMI, 38 (84.4%) patients with STEMI and seven (15.6%) patients with NSTEMI. There were significant differences of left ventricle end diastolic volume (LVEDV) baseline from 76±29.69ml/m2 to 98.11±36.84ml/m2 after 12 week follow-up (p=0,003). There was significant correlation between high baseline soluble ST2 with and low GLS baseline with LV remodeling (p=0.015). High baseline soluble ST2 and low GLS value can predict LV remodeling in patients with AMI.

Left Atrial (LA) pressure and the trans-mitral pressure gradient chronically increases in Mitral Stenosis (MS), which results in LA enlargement and Pulmonary Hypertension (PH). We investigate the Left Atrial Volume Index (LAVI) as an indicator of severity and PH in MS. Fifty-nine subjects with MS (27 men and 32 women) mean ages 41.3±9.51 y.o were included in this study. We examined the correlation of LAVI and parameters of MS severity, and PH (Planimetry, MVA-PHT, MVA-VTI, MV-PHT, MV meanPG, TRmaxPG, and EstPASP). Most of the subjects had severe MS (77%), mild PH (40%) and AF (80%). LAVI value markedly increased in this study (Mean: 83.79 ± 38.32 ml/m2). In subjects with severe MS, LAVI was significantly higher than that in moderate MS (91.88±38.41 vs 54.83±19.28, p<0.05). LAVI was significantly correlated with Planimetry, MVA-PHT, MVA-VTI, MV-PHT, MV MeanPG, and EstPASP (-0.40; -0.42; -0.29; 0.42; 0.27 and 0.29, p<0.05, respectively). LAVI cut-off value as an indicator for severe MS was 59.72 ml/m2, with the sensitivity and specificity was 75.3% and 66%, respectively. LAVI was correlated well with severity and PH parameters in MS. LAVI also can be used as an indicator for severe MS.

In cardiology, stem cell therapy is currently being used. Adipose Mesenchymal Stem Cell (AMSC) is a cell culture expected to give a clinical improvement in patients. One of the methods to transfer the stem cell is cardiac catheterization assisted by contrast. There are no studies concerning the effect of contrast on proliferation or viability of stem cells. This study was designed to see the effect of contrast on the growth of AMSC culture in vitro. This research is an experimental post-test control group study. The samples were obtained from the thawing process at the Institute of Tropical Disease (ITD) Unair. The samples were cultured and checked immunohistochemically, divided into two groups, which are the treated group given iodixanol contrast and control group. The treated group was divided into se subgroups incubated 24 hours, which received 1mg/mL, 500µg/ml, 250µg/ml, 125µg/ml, 62.5µg/ml, 31.25µg/ml and 15.625µg/ml. AMSC proliferation was assessed by microtetrazolium (MTT) Cell Proliferation Assay and analyzed using T 2 free sample test and Analysis of Variance (ANOVA). MTT Cell Proliferation Assay showed no significant differences in AMSC proliferation on iodixanol contrast media compared to the control group. Iodixanol contrast does not affect AMSC proliferation.

Cardiovascular disease is still the leading cause of death worldwide. Atherosclerosis is the most common type of cardiovascular disease and can be caused by various factors, such as genetics and lifestyle. Cells need energy to maintain their integrity and function. Energy that is often used is adenosine triphosphate (ATP). Atherosclerosis can cause myocardial ischemia and induced reduction of ATP levels, so that that not only affects cellular energy, but also alters the normal function. D-ribose is a pentose carbohydrate that has been shown to increase cellular energy levels and improve function after ischemia in pre-clinical studies. It has shown potential benefits in clinical evaluation. This article aims to explain the role of D-ribose in increasing energy levels and myocardial function in ischemic cardiovascular disease.

Hematological parameters provide independent information as well as troponin in non-ST-Elevation-Acute-Coronary-Syndrome (NSTE-ACS) patient. Refractory angina in NSTE-ACS patients significantly transforms this optimal management due to risk enhancement. This study aims to prove the association of white blood cell (WBC) to mean platelet volume ratio (WMR) with troponin and authenticate the best parameter for refractory angina prediction in NSTE-ACS patients. This observational study was conducted in ICCU Dr. Soetomo General Hospital, Surabaya. There were 49 NSTE-ACS patients recruited as the study subject. Complete Blood Count (CBC), High Sensitivity Cardiac Troponin I (hs-cTnI) and CKMB examinations were conducted at the time of admission. We observed angina symptom for three months. The mean age of the patients was 60.8±8.67 years, and 75.5% of them were male. Elevated hs-cTnI level was found in 83.7% of study subjects. WMR significantly correlated with hs-cTnI (r=0.434 p=0.002). Refractory angina was found in 14.3% of study subjects. There was a positive moderate correlation of WMR and refractory angina (r=0.534 p=0.000), a positive moderate significant correlation of hs-cTnI and refractory angina (r=0.470 p=0.001). No significant correlation of other parameters. This study proved that WMR was an independent hematological predictor for refractory angina event in NSTE-ACS patients with higher significance level than hs-cTnI.

Studies had reported an increasing trend of coronary artery disease (CAD) cases in the navy population. However, the severity of the CAD among different navy ranks is yet to be studied. The Gensini scoring system is a popular and developed objective method to quantify the CAD severity through the coronary angiographic findings. In this retrospective cross-sectional study, researchers enrolled 171 patients referred to the Indonesian Navy Hospital of Dr. Ramelan who underwent elective coronary angiography between January 2019 and June 2019. Researchers divided the study population into five groups of civilians, enlisted, noncommissioned officers, new commissioned officers and middle-rank officers. Post-hoc least significant difference (LSD) test showed the average Gensini Score of civilian (41.54 ± 48.06) is higher than enlisted (13.37 ± 26.25; p=0.031), new-commissioned officers (13.21 ± 26.76; p=0.020), and middle-rank officers (21.23 ± 33.17; p=0.017), but not for non-commissioned officers (45.61 ± 42.62; p=0.657). Non-commissioned officers have a significantly higher Gensini Score than enlisted (p=0.027), new-commissioned officers (p=0.019) and middle-rank officers (p=0.023). This study concludes that the majority of Indonesian Navy personnel had a lower Gensini Score compared to civilians but not for non-commissioned officers. This study suggests that civilian and non-commissioned officers may have a higher risk of developing severe CAD.

Assessment of left ventricular function in patients with chronic heart failure is important for determining prognosis and treatment plans. The prognostic values of the myocardium and global ventricular functions remain unclear. This cross-sectional study included 30 subjects obtained through purposive sampling. Global longitudinal strains (GLS) is used to assess the left ventricular systolic function and Tei index (TI) is used to assess both global systolic and diastolic ventricular function. SHFM scoring was calculated based on existing patient data. The mean GLS-left ventricle value was -8.08 ± 3.98, whereas TI value was 0.65 ± 0.14. GLS-left ventricle had significant negative correlation with estimated one and five years mortality based on SHFM score (r = - 0.676 and p = 0.0001) whereas TI had a significant positive correlation (r = 0.745 and p = 0.0001; r = 0.738 and p = 0.0001). GLS-left ventricle had a significant negative correlation with an estimated one and five years mortality based on SHFM score, whereas TI had a significant positive correlation. Hence it is suggested that GLS-left ventricle and TI can be a prognostic factor.

Antithrombotic therapy is recommended in atrial fibrillation (AF) management due to high risk of stroke. The assessment of stroke risk, as well as risk of bleeding, can help clinicians to make optimal management decisions. This study aimed to assess the stroke and bleeding risk using the ATRIA score and to compare the drug utilization pattern of antithrombotic therapy in post-ischemic stroke patients with AF comorbidity. This study is a single-center, retrospective observational study. From June 2009 to April 2019, we enrolled 165 post-ischemic stroke patients with AF comorbidity (mean age 68.24years; 47.3% female). One hundred nineteen patients were first stroke patients and 46 were recurrent stroke patients. Antiplatelets were predominantly prescribed (n=106, 64.2%). Out of 106 patients prescribed with antiplatelets, 39 (23,6%) patients had high a ATRIA Stroke Risk score, while as per ATRIA Bleeding Risk score, 66 (40%) patients had a low score. Conversely, an anticoagulant was rarely prescribed. A total of only 59 (35.7%) patients were prescribed with an anticoagulant, as single or combination. Out of 59 patients, an anticoagulant was commonly prescribed in high ATRIA Stroke Risk score patients (n=40, 24,3%). While as per ATRIA Bleeding Stroke score, an anticoagulant was commonly prescribed among low bleeding risk patients (n=47, 28.5%).

Hypertension is still the most prevalent of non-communicable diseases in Indonesia. Renovascular hypertension is one type of secondary hypertension. It is commonly caused by the presence of renal artery stenosis (RAS). Whereas, atherosclerosis (ARAS) and fibromuscular disease (FMD) are the most common causes of RAS. Early diagnosis is necessary because it has the potential to be cured by eliminating stenosis of the renal artery. However, the signs and symptoms of renovascular hypertension are not specific. The supporting examination to diagnose RAS is also expensive. So, screening in the population at risk is needed. The examinations to prove the presence of RAS are arteriography, captopril renogram, renal ultrasonography, renal Doppler ultrasonography, magnetic resonance angiography (MRA), and computed angiographic tomography (CTA). Until now, three therapeutic modalities can be selected in the management of renovascular hypertension; pharmacological therapy, surgical intervention, percutaneous intervention angioplasty with and without stenting. This narrative review summarizes the literature focused on the diagnosis and therapy of RAS.

Background: Angina can be caused by atherosclerosis in Coronary Artery Disease (CAD) patients either in Stable Coronary Artery Disease (SCAD) or Acute Coronary Syndrome (ACS). Histamine as a mast cell-preformed mediator is suspected to play a role in atherosclerosis. However, its mechanism is yet to be established and there is a lack of these data in the CAD population. To confirm the distinctness of plasma histamine level in patients with Acute Coronary Syndrome and Stable Coronary Artery Disease Patients, this research was an observational analytic study with transversal design in 49 CAD patients by purposive sampling which consists of 25 ACS patients (72% men, mean age 55,6±9,66 years) and 24 SCAD patients (83,3% men, mean age 52,71±8,03 years). The level of plasma histamine was measured using a Histamine ELISA-Kit. Median values of plasma histamine level in ACS group and SCAD group were 30,79 ng/ml (5,85-36,09 ng/ml) and 26,42 ng/ml (0,30-41,39 ng/ml). Comparison analysis on the median value of plasma histamine level between two groups was done with Mann-Whitney U Test and showed a statistical difference between two groups (p=0,011). There are significant differences in plasma histamine level between Acute Coronary Syndrome and Stable Coronary Artery Disease Patients.

In myocardial infarct patient with heart failure, left ventricular (LV) function evaluation after myocardial infarction provides prognostic information. However, the relationship between exercise capacity and LV function has not been fully explored. This study aims to analyze the correlation of LV function with functional capacity in acute myocardial infarct patient with heart failure. From 33 patients who fulfilled the inclusion and exclusion criteria, treadmill and echocardiography were examined (LVEDd, myocardial performance index (MPI), E/E' diastolic function, LV Stiffness). The results are then statistically analyzed using SPSS. The mean LV ejection fraction is 44.27 ± 9.0% by Teich, and 40.55 ± 8.3% by Biplane. The value of the global MPI function is (0.60-0.90). The average E/A ratio is 1.0 ± 0.5, deceleration time (DT) is > 220m / sec, and E / E ratio is 11.46 ± 5.82ms. The functional capacity value is 3.4 (1.1-8.4) METS. There is a significant positive correlation of LV systolic function and functional capacity and significant negative correlation between MPI and functional capacity in myocardial infarct patients with heart failure. Furthermore, there is a non-significant correlation between diastolic function and functional capacity.

Fibrinogen is considered as a risk factor associated with cardiovascular disease, especially acute myocardial infarction (AMI). The role of increasing levels of fibrinogen in the thrombosis shows that there is an effect that causes the pathway to form a thrombosis. Increased plasma high-density lipoprotein (LDL) cholesterol can also induce the development of atherosclerosis and is associated with AMI events. This study was an observational analytic study using a cross-sectional approach, carried out from August-November 2015 in Dr. Soetomo Hospital Surabaya. Samples were 67 subjects who fulfilled inclusion and exclusion criteria. A total of 67 subjects were assessed, 47 (70.15%) were males, and 20 (29.85%) were females. The mean age was 5.07 ± 11.02 years old, ranging from 30 to 85 years. AMI was diagnosed in 49 patients (26.87%). Management of AMI patients consisted of conservative medical therapy (42.86%), thrombolytic therapy (18.37%) and PPCI (38.77%). The statistical analysis revealed significant differences in plasma fibrinogen and LDL cholesterol levels between the AMI patient group and the control group. There was a significant correlation between fibrinogen levels and LDL cholesterol levels. Fibrinogen and LDL cholesterol levels are correlated with AMI risk factors. In subjects with AMI, there were higher fibrinogen and LDL cholesterol levels compared to non-AMI subjects.

Protein p53 has an important role in atherosclerosis plaque as part of senescence cell vascular. Increased vascular aging process is characterized by several parameters, one of which is an increase in carotid intima media thickness (CIMT). CIMT is one of the non-invasive methods that can determine vascular age, which is a safe, fast and inexpensive method of assessing atherosclerosis. This study was a correlational study conducted at cardiovascular outpatient clinic from August until November 2015. Serum p53 levels were measured by human p53 ELISA kit. CIMT is measured by B-mode ultrasound. The CIMT value was based on the normogram of the Atheosclerosis Risk in Communities Study. Spearman rank test was used to analyze the relationship between serum p53 and vascular age. There were 19 men and 19 women in the subject of this study. The average vascular age is 54.34 + 8.5 years. Serum p53 levels were positively correlated with vascular age in the subject group of this study (p <0.001; r = 0.58). There is a positive, strong and significant correlation between serum p53 and vascular age levels determined by CIMT in patients with moderate cardiovascular risk factors.

Nowadays obesity, defined as an imbalance between food intake and exercising, has become a health concern worldwide. Obesity triggers many diseases, one of them being diabetes melitus (DM) type 2. Atherosclerosis is known to be linked with CD 36 and it can be identified as platelet integral membrane glycoprotein IV. CD 36 is known as thrombospondin-1 (TSP-1) which is found on gustatory cells, extracellular matrix (ECMs) and platelete a granules, therefore it has strong relationship with atherosclerosis. CD 36 can bind to oxLDL and induces prothrombotic state. Inspite of that, ENaC and AQP 2 also have a strong effect on heart, especially their role are often related to the heart failure (HF) because sodium and water are thought to be mediated through activation of arginine vasopression (AV), neurohormonal activity, the renal-angiotensin-aldosteron system (RAAS), and atrial natriuretic peptide that maintains cardiac output and blood pressure. This article is focused on the relationship of CD 36, ENaC, and AQP 2 effects' on heart, including the molecular mechanism. This understanding needed to treat and to cure the heart diseases and prolong the sufferers life expectancy.

The inflammatory process plays an essential role in the process of atherosclerosis and the response of ventricular recovery after myocardial infarction. Galectin-3 is a mediator derived from macrophages and endothelium that is actively involved in various aspects of the inflammatory cell behavior. Galectin-3 increases in the formation of fibrosis and scar, which is a maladaptive response to injury and infarction such as ST-segment elevation myocardial infarction (STEMI). Wall Motion Score Index (WMSI) is a semiquantitative visual assessment of the dynamic left ventricular wall. WMSI has an association with left ventricular ejection fraction in assessing prognosis after myocardial infarction. This study aimed to determine the correlation of increasing galectin-3 level with WMSI in STEMI patients. A cross-sectional study with purposive sampling was done. Galectin-3 levels were measured using R&D System ELISA Quantikine® Human galectin-3 Immunoassay with units ng/ml. WMSI measured by 2D-echocardiography. We enrolled a total of 35 STEMI patients, 28 (80%) were males. The result of measurement of galectin-3 levels in STEMI patients increase significantly (12,545±6,504 ng/mL) and moderate positive correlation with WMSI (r=+0,429, p=0.01). The result of the study showed there is a significant positive correlation between serum galectin-3 level with WMSI in STEMI patients.

Tryptase, an enzyme secreted by mast cell, is suggested to play a significant role in the pathophysiology of acute coronary syndrome (ACS) and subsequent ventricular remodeling (VR). This study aimed to understand the correlation between the serum level of tryptase and VR in patients with ACS after one month of onset. Sampling method was total sampling where patients with ACS enrolled in the study were allocated into two groups based on their serum tryptase level, lower level (n=13) and higher level (n=12) groups. All subjects underwent echocardiography examination on admission to obtain their initial data and they were reevaluated one month later for the signs of VR. The occurrences of VR were examined by echocardiography with LVEDP and LVESV used as the VR parameters. Fisher Exact Test showed no significant difference between both groups in term of VR (p=0.668). The contingency coefficient analysis revealed no correlation between tryptase level and the occurrence of VR (p=0.113). However, the multiple regression analysis suggested that LVEDP and LVESV demonstrated multicollinearity to tryptase and VR. Although the current study concluded no correlation between tryptase level and VR following ACS, a prospective study with longer follow-up time is expected to gain more information.

Levofloxacin is a fluoroquinolone antibiotic which is used widely in treating various infections. Despite this benefit, Levofloxacin has a cardiac side effect called drug-induced long QT syndrome (diLQTS), which is associated with Torsades de Pointes (TdP). In this study, our objective was to analyze the incidence of diLQTS associated with Levofloxacin use in Ahmad Dahlan Hospital Kediri. This study included patients who were admitted to Ahmad Dahlan Hospital Kediri from March-May 2019 and received Levofloxacin 500mg therapy once daily. An electrocardiogram was performed before and after initiation of therapy. Prolonged QTc was defined by heart rate-corrected QT ≥450ms for male and ≥470ms for female, calculated using Bazett formula; or if the prolongation of QT interval is >60ms from baseline. Acquired data were analyzed using Paired T-test. Of all 24 patients who received Levofloxacin, six patients developed long QTc. Two of which had >60ms difference from base ECG (p-value >0.05). No symptom of TdP was reported. The incidence of diLQTS associated with Levofloxacin use was 25%. Risk factor stratification and ECG monitoring should be done from the beginning of the therapy.

Arterial stiffness (AS) is an independent predictive value of cardiovascular diseases. Patients that have chronic kidney disease have high mortality and morbidity of cardiovascular events. Increased AS is believed show cardiovascular damage. Therefore, this study was held to assess correlation of arterial stiffness to left ventricular mass index (LVMI) and diastolic function in stage 3 to 4 of non-diabetic CKD patients. This is a study using cross-sectional approach to 40 outpatients with stage 3 and 4 of CKD in Dr. Soetomo General Hospital Surabaya. Carotid ultrasound and β stiffness index formula was utilized to study carotid arterial stiffness (CAS) while echocardiography was used to assess diastolic function and LVMI. Patients that had severe heart valve disease, coronary artery disease, atrial fibrillation, congenital heart disease, history of diabetes mellitus, history of active smoking and cerebrovascular disease were not included in this study. There is significant relation between CAS with E/E' (r=0.517, p=0.001) and LVMI (r=0.396, p=0.011), also between SBP with LVMI (r=0.491, p=0.001). SBP has more significant role for LVMI (p<0.001) than CAS. Arterial stiffness had significant positive relation with E/E' and LVMI in patient with stage 3 and 4 of non-diabetic chronic kidney disease.

Coronary heart disease incidence in octogenarian keeps increasing in line with increasing population of elderly. In elderly, there were more non-ST-elevation myocardial infarction (NSTEMI) patients compared to the ST-elevation myocardial infarction (STEMI) ones. In elderly, thrombolytic therapy is thought to have higher bleeding incidence compared to cardiac intervention. Aim of this study was to determine the prevalence of bleeding associated with thrombolytic therapy in octogenarian patients with STEMI during 2018 at Buleleng General Hospital. This is a descriptive retrospective study conducted on octogenarian patients with STEMI who received thrombolytic therapy. Additionally, bleeding incidence that occurred during treatment is also observed. In 2018, 62 octogenarian patients were admitted with acute coronary syndrome (ACS). According to patient medical records, 16 patients were diagnosed with STEMI and six of them received thrombolytic therapy. Bleeding effect was recorded in all patients with details of two patients experienced oral mucosa bleeding and four patients experienced urinary tract bleeding. Out of all octogenarian patients with STEMI who were admitted, bleeding occurred in all patients in which urinary tract bleeding is the most common complication.

Myocardial infarction (MI) may alter left ventricular (LV) systolic function, which, in turn, may reflect on functional capacity. Objective systolic function assessment using 2D speckle-tracking echocardiography is promising to assess the correlation between LV longitudinal strain and strain rate with functional capacity in post-MI patients with heart failure. A cross-sectional study was done on 33 consecutive post-MI patients with class I-II NYHA heart failure visiting the cardiology outpatient clinic of Dr. Soetomo General Hospital, Surabaya. The resting echocardiogram was taken, followed by a treadmill stress test using Naughton protocol. Appropriate statistical analyses were used to determine the correlation of systolic longitudinal strain and strain rate with exercise capacity. Study subjects were 69.7% males with age 58.45±6.2 years old. EF by Biplane was 40.55±8.26%; with global peak longitudinal strain –12.23±5.19%, and strain rate – 0.67±0.25s−1; and peak exercise capacity 3.69±1.8 METs. Using Pearson's test, there was a strong negative correlation of systolic longitudinal strain and strain rate with functional capacity (r = –0.577, r = –0.607respectively; p<0.05). LV systolic longitudinal strain and strain rate were strongly correlated with functional capacity in post-MI patients with heart failure.

Abundant scoring systems are available to assess the severity of coronary artery disease (CAD) and its intervention. However, the majority of them require advanced technologies. CHA2DS2-VASc-HSF is a novel and simple risk scoring, easily used for screening in primary care level. We hypothesize that CHA2DS2-VASc-HSF is predictive for severe CAD and indicative for coronary artery bypass grafting (CABG). Additionally, we compared its predictive value with CHA2DS2 and CHA2DS2-VASc score. A total of 210 consecutive patients who underwent elective coronary angiography were enrolled in our study. Anthropometric, laboratory, angiographic findings, and patient history were obtained from medical records and used to calculate CHA2DS2, CHA2DS2-VASc, and CHA2DS2-VASc-HSF score. Severe CAD is defined as Gensini Score >20. CABG indication was defined based on Class I recommendation from the American Heart Association (AHA). Statistical analyses were done using SPSS 25.0. Receiver operating characteristic (ROC) curve analysis showed the CHA2DS2 score (AUC [Area Under the Curve], 0.630; 95% CI, 0.555–0.706; p = 0.001), CHA2DS2-VASc score (AUC, 0.680; 95% CI, 0.608–0.752; p=0.000), and CHA2DS2-VASc-HSF score (AUC, 0.785; 95% CI, 0.723–0.846; p=0.000) were predictive of severe CAD. CHA2DS2-VASc-HSF score (AUC, 0.841; 95% CI, 0.711–0.971; p=0.00) were predictive of CABG indication. The CHA2DS2-VASc-HSF score provides the highest predictive value for severe CAD and CABG indication compared to the CHA2DS2 and CHA2DS2-VASc score, suggesting that CHA2DS2-VASc-HSF score may be used in primary care settings to suggest referral for coronary angiography and predict CABG possibilities.

Early treatment in acute coronary syndrome plays as key role in short-term and long-term outcome. Some studies showed that statin treatment may improve long-term outcomes in post-ACS patients as secondary prevention. The most effective time to give statin in ACS patients is not well-known. The aim of this study is to review previous studies as to when is the best time to initiate statin therapy to reach the best long-term outcome in patients with ACS. PubMed and Medline database were searched with keywords in search engine. The inclusion criteria were: 1) trials that compared one of the statin drugs to placebo or standard care; 2) follow up at least 30 days; 3) publication between 2000-2018. Total of six studies was collected in this review. Many studies showed that early treatment with statin in patients with ACS in admission is associated with reduced one-year mortality. Moreover, early statin therapy reduced one-year major adverse cardiac effect. Statin therapy should be administered early during hospitalization for ACS on the basic data that early therapy with statin is proven reduced one-year mortality and MACE. Further investigation still needs to specify when is the most effective time to give statin in patient with ACS.

Arteriovenous fistula (AVF) is the vascular access of choice in prevalent hemodialysis end-stage renal disease (ESRD) patients. However, there was a significant proportion of early AVF failure and its predictive factor was conflicting in several studies. We conducted a retrospective cohort study in 225 AVFs created in 159 patients. The purpose of this study was to identify the predictive factors of AVF early failure. The data variables included age at AVF creation, sex, history of diabetes, hypertension, cigarette smoking, AVF location and side, history of subclavian tunneled dialysis catheter and history of preoperative ultrasound mapping. This information was collected by interviewing the patient and by AVF scar inspection. AVF that was never coming into use was classified as an early failure. AVF creation in the wrist was significantly associated with a higher early failure rate (29.9%) compared with AVF creation at the elbow (4.4%) (p < 0.001). There was no significant association in terms of AVF early failure in terms of the other variables. We concluded that wrist AVF is significantly associated with early failure. However, this finding should not preclude the National Kidney Foundation's recommendation of using wrist AVF for the first choice of vascular access to conserve more proximal access sites for future use.

Obesity constitutes a major health issue which contributes as the risk factor of cardiovascular disease. This cross-sectional study included 50 consecutive patients with HHD (Hypertensive Heart Disease) in the Cardiovascular Department of Dr. Soetomo General Hospital. The echocardiographic examination was done using GE vivid 7. The statistics were evaluated using SPSS 25.0. The research showed that different grades of BMI (body mass index) were positively correlated with Left Atrial (LA) major (r=0.335), Right Atrial (RA) Major (r=0.371), Left Ventricle end Diastole (LVD) Mass (r=0.341), Left Ventricle end Sytole (LVS) Mass (r=0.303), Left Ventricle Posterior Wall end Diastole (LVPWD) (r=0.369), Left Ventricle Posterior end Systole (LVPWS) (r=0.391), and inversely correlated with Left Ventricle Sphericity Index (LVSI) Doppler (r=-0.376). Obese (BMI>30) patients have a significantly lower ejection fraction compared to normoweight (BMI<25) patients (64.3±3.67% vs 62.12±0.98%, p=0.046). In conclusion, the grade of BMI of the HHD patient is associated with an increased volume of the left atrium and ventricle. This suggests that obese patient with HHD should be assessed carefully for atrial and ventricle enlargement.
