Authors: Ibrahim Puji Astuti 
Published: May 2020

Carbon Steel 1018 is a low carbon steel having a carbon content (C) of 0.14-0.20% (<0.30% C). Low carbon steel is commercially known as mild steel. Corrosion is one way to prevent corrosion caused by the environment. Corrosion inhibitor are taken between the Crude Corrosion Inhibitor and Gas Corrosion inhibitor on Carbon Steel 1018 using the polarization method. Corrosion inhibitors work by making passive layers in the form of thin films or films on the surface of the material used as a barrier between metals and corrosive media. The analysis method used is polarization. Inhibition Efficiency Results obtained for Gas Corrosion Inhibitors (1A) at 10 ppm 96.86%, 20 ppm 59.74%, 30 ppm 74.48%. The Crude Corrosion Inhibitor (2A) results obtained inhibition efficiency for 10 ppm 99.57%, 20 ppm 77.69%, and 30 ppm 12.63%. The optimum value for the Gas Corrosion Inhibitor and Crude Corrosion Inhibitor is at 10 ppm at 96.86% and 99.57%.Â Keywords: carbon steel,crude corrosion inhibitor, corrosion , gas corrosion inhibitor, inhibitor

Published: May 2020

Background : Systemic lupus erythematosus (SLE) is a systemic autoimmune disease involving multiple organs including kidney and known as lupus nephritis (LN). Lupus nephritis has a poor prognosis after a 10-years onset, more than 25% will be ended by end stage renal disease. There are glomerular and tubulointerstitial tissue damages due to immune complex deposits in LN which is activating inflamation cascade and causing disfunction of glomerular filtration and tubular reabsorption resulting proteinuria. In LN, proteinuria is used to diagnose, to assess the disease activity and to monitor the therapy. The gold standard of proteinuria is 24-hour urine protein examination, but the process ofcollecting in 24 hour urine is difficult, then the result is less accurate and reliable. Another alternative parameter is spot urine protein/creatinine ratio. Several studies have found a positive correlation between spot urine protein/creatinine ratio and 24-hour urine protein levels, but in LN, the results are various.Objective: The aim of this study was analyzing the correlation between spot urine protein/creatinine ratio and 24-hour urine protein in lupus nephritis.Methods: The study was conducted at Dr. Hasan Sadikin Hospital, Bandung, West Java, Indonesia in October 2014 to December 2014. The subjects were 45 patients with lupus nephritis based on the criteria of the American College of Rheumatology. The study analyzedcorrelation through cross-sectional model. Results: The results of Spearman correlation test analysis showed a significantly strong positive correlation between spot urine protein/creatinine ratio and 24-hour urine protein levels in lupus nephritis (rs =0.96; p <0.001). Based on the degree of proteinuria there was a strong positive correlation between spot urine protein/creatinine ratio and 24-hour urine protein levels in lupus nephritis significantly on the degree of protein <1 g/24-h (rs = 0.91; p <0.001) and at 1–3.5 g/24-h (rs = 0.73; p<0.05).Conclusion : There is a significant strong positive correlation between spot urine protein/creatinine ratio and the 24-hour urine protein levels in lupus nephritis, so it is recommended to use spot urine protein/creatinine ratio, as an alternative quantitative examination in lupus nephritis.Keywords: lupus nephritis, 24-hour urine protein, spot urine protein/creatinine ratio

Published: May 2020

Background: The operative treatment of cardiac diseases remains associated with systemic inflammation and a suboptimal outcome in many patients. These inflammatory changes are manifested by systemic hypotension, myocardial failure, increased vascular permeability and consequent dysfunction of organs such as the lungs, gut and brain. In general terms, sympathetic innervations of the small arteries and arterioles allows vasoconstriction, thereby increasing resistance to blood flow, whereas innervations of the large arteries and veins decreases the volume in these vessels, resulting in the redistribution of blood volume. This study was conducted to determine the effect of vasodilator drugs on duration of vasodilatation in patients undergoing coronary artery bypass grafting (CABG) with Cardiopulmonary bypass (CPB).Methods: We evaluated prospectively the effect of vasodilator medications before CABG surgery on hemodynamic variables and use of vasoactive drugs. We studied 30 patients with good left ventricular function allocated randomly to continue vasodilator drugs before cardiac surgery. Arterial pressure, Cardiac output, systemic vascular resistance and use of vasoactive drugs were recorded during anaesthesia, perioperative and in the early postoperative period.Results: Patients who using vasodilator drugs before cardiac surgery had not significant relationship between vasodilator drugs and vessels reactivity (vasoconstriction & vasodilatation). However, these patients required more vasodilator drugs to control hypertension after CPB and in the early postoperative period.Conclusion: There was no difference in hypotension at the onset of CPB or in the use of vasodilator drugs before cardiac surgery. We conclude that vasodilator drugs before cardiac surgery did not have sufficient effect to be recommended routinely.

Background: Infectious diseases are common causes of presenting in emergency having severe signs and symptoms. Having significant mortality and morbidity are on the rise in Pakistan. The objective of the study was to determine the prevalence of infectious diseases in paediatric population.Methodology: We studied 200 consecutive patients from 1 month to 12 years of age presenting with infectious diseases. Their detailed history was then taken including symptoms at presentation and the type of infection was assessed with the help of history and laboratory investigations. Following are the common infectious diseases including pneumonia, meningitis, enteric fever, malaria, measles, tuberculosis, acute watery diarrhoea.Results: Frequency wise infectious diseases are pneumonia (63.5%), meningitis (20%), acute watery diarrhoea (8.5%), enteric fever (4%), malaria (2%), tuberculosis (2%), and no measles case found. Infectious diseases are more common in rural areas than urban areas and success after treatment is more (49.5) than death (2%) but a bad impact is that (48.5%) patient went without treatment.Conclusion: This data is taken in winter season that is why Pneumonia is most common infectious disease, second most common infectious disease is meningitis, and others are acute watery diarrhoea, enteric fever, malaria and tuberculosis in our patients. The awareness of risk factors amongst the public is low. Thus, there is an urgent need to create more and more awareness about the preventive aspects and healthier life style behaviour in our community.

Published: May 2020

The competitive healthcare system and healthcare environment, modern hospitals with substantial investment, healthcare reforms, availability of specialized persons in hospital management, health services management, the success of quality management programs in developed nations and high interest of international health organizations like WHO has led the developing countries like Pakistan to pay due attention to quality in national healthcare system. Since the time of independence healthcare system in Pakistan is striving for improvements. Despite of the physical infrastructure and availability of qualified workforce for service delivery there are gaps in strategic and operational planning which resulted in poor quality health services. The leaders in healthcare has little awareness that the quality management is an organized specialty to improve the quality of healthcare. It is need of the hour that healthcare leaders in Pakistan must integrate quality improvement activities in strategic and operational planning process of healthcare system. This the only way to maximize the benefits of healthcare system and restore the rapidly deteriorating public trust.

Published: May 2020

Background: Hepatitis B virus (HBV) reactivation can be asymptomatic or manifest as fatal fulminant hepatitis. Most international guidelines recommend screening patients prior to immunosuppressive therapy.
Aims: To determine HBV screening rates and modalities in patients receiving chemotherapy at the American University of Beirut Medical Center.
Methods: A retrospective cohort review of electronic health records of adult patients who received chemotherapeutic agents, between June 2015 and June 2016. Patients clinical characteristics were documented. Adequate screening was defined as performing all: HBsAg, HBs Abs, and anti HBc Abs(total).
Results: A total of 1547 patients were initially assessed. 45.6% were males with a mean age of 56. 382(30%) had hematologic malignancies, of whom 111 underwent HSCT. Of those included, 303(24%) patients were screened by at least one test for HBV and 42(3.3%) for HBsAg, anti HBc Abs and HBs Abs.
Patients who were appropriately screened were significantly younger(p=0.008) and more likely to have hematologic malignancies (n=35, 83.3%, p<0.0001). Among patients with hematologic malignancies, appropriately screened patients (n=35) were younger (p=0.042) and had a history of HSCT(n=19, 54.3%, p=0.001).
Conclusion: Rates of screening for HBV prior to chemotherapy at our medical center are low, and not always complete or adequate. There is an urgent need to implement a better screening policy.

Abstract
The population of Milky Way satellite galaxies is of great interest for cosmology, fundamental physics, and astrophysics. They represent the faint end of the galaxy luminosity function, are the most dark-matter-dominated objects in the local universe, and contain the oldest and most metal-poor stellar populations. Recent surveys have revealed around 60 satellites, but this could represent less than half of the total. Characterization of these systems remains a challenge due to their low luminosity. We consider the gravitational-wave observatory LISA as a potential tool for studying these satellites through observations of their short-period double white dwarf populations. LISA will observe the entire sky without selection effects due to dust extinction, complementing optical surveys, and could potentially discover massive satellites hidden behind the disk of the Galaxy.
