Published: August 2020

Since the start of the
COVID-19 pandemic, patients with diabetes were rapidly recognized as a
high-risk population for severe disease. Indeed, a high prevalence of diabetes
among patients with COVID-19 who required hospitalization has been consistently
reported, reaching 33.8% in 5,700 people hospitalized for COVID-19 in New York City area (1). In addition, diabetes was associated with more than a double risk of intensive
care unit (ICU) admission and more than a triple risk of death (2). However, precise
data regarding the type of diabetes are scarce. We report here the clinical
characteristics and early prognosis of patients with type 1 diabetes (T1D)
hospitalized for COVID-19 in the nationwide multicenter observational CORONADO (CORONAvirus-SARS-CoV-2 and Diabetes Outcomes) study (3).

Background: The aim of this trial was
to compare the efficacy of real-time and intermittently-scanned
continuous glucose monitoring (rtCGM and isCGM, respectively) in
maintaining optimal glycemic control.

Methods: In
this randomized study, adults with T1D and normal hypoglycemia awareness (GOLD score <4) used rtCGM (Guardian Connect Mobile) or
isCGM (Freestyle Libre) during 4 days of physical activity (exercise phase) and in subsequent 4 weeks at home (home
phase). Primary endpoints were time in hypoglycemia (<3.9 mmol/l [<70
mg/dl]) and time in range (3.9-10.0 mmol/l [70-180 mg/dl]). The isCGM group wore an additional
masked Enlite sensor (iPro2) for 6 days to check for bias between the different
sensors used by the rtCGM and isCGM systems.

Results: Sixty adults with T1D (mean age 38±13 years, A1C
62±12 mmol/mol [7.8±1.1%]) were randomized to rtCGM (n=30) or isCGM (n=30). All participants
completed the study. Percentage of time in hypoglycemia (<3.9 mmol/l [<70
mg/dl)) was lower among rtCGM vs. isCGM participants in the exercise phase (6.8±5.5% vs. 11.4±8.6%, respectively; p=0.018) and during the home phase (5.3±2.5% vs. 7.3±4.4%, respectively; p=0.035).
Hypoglycemia differences were significant and most notable during the night.
rtCGM participants spent more time in range (3.9-10 mmol/l [70-180 mg/dl]) than isCGM participants throughout
both the exercise (78.5±10.2% vs. 69.7±16%, respectively; p=0.0149) and home (75.6±9.7% vs. 67.4±17.8%, respectively; p=0.0339)
phases. The results were robust to the insignificant bias between rtCGM and
isCGM sensors that masked CGM found in the isCGM arm.

Conclusion: rtCGM was superior to
isCGM in reducing hypoglycemia
and improving time in range in T1D adults with normal hypoglycemia awareness,
demonstrating the value of rtCGM alarms during exercise and in daily diabetes
self-management.

Base64 Sebagai Kunci Keamanan pada One Time Pad (OTP)
Authors: Sulaiman Oris Krianto , Nasution Khairuddin , Prayogi Satria Yudha
Published: August 2020

Message security in communication is very important to maintain the confidentiality and integrity of messages. The message that is sent must be conveyed in its entirety and only delivered according to its purpose. One Time Pad or OTP is an algorithm that can encrypt messages into ciphertext so that message security can be guaranteed. OTP is a symmetric cryptographic algorithm, that is, the key for encryption and decryption is the same. To perform encryption, the OTP plaintext length must be the same as the key length. This will make it difficult when there is a very long length of plaintext, so the key must also adjust it. OTP keys also have a weakness if a key has been used more than once. Therefore a key builder is needed. In this research, the key generator used is base64. Base64 is used to change the bits of plaintext that will be used by OTP. In this study, base64 can encode plaintext to be used as an OTP key so that it succeeded in making the key generator from base64 encoding.

Authors: Nazreen Aqila Zulaikha , Jai Junaidah , Abdulbari Ali Sherif , Mohamed Manshor Norasmah
Published: August 2020

Bioplastic has been extensively studied due to its ability to replace synthetic plastics. Its biodegradability is seen as a significant advantage to be used as edible food film packaging. As a food packaging, the film should be able to retain moisture from the food and the surrounding environment. The ability of the film to retain moisture varies with the type of material the film is made of. Moisture sorption isotherms are used to study the moisture content and water activity of food or film packaging at a given temperature. There are many models to describe moisture sorption isotherm. Some researchers modified the models to account for varying temperatures. The purpose of this paper is to review types of adsorption isotherms and the most common models used for film packaging. The general and modified models are described in this paper as well as its best-fit use on film packaging. The advantages of studying adsorption isotherm include shelf-life determination, physical and chemical stability, and others.

Authors: Ismail Normah , Kamal Mohd Faizzuddin Mustapa , Ya Kyaw Zay
Published: August 2020

The antioxidant activities and oxidative stability of palm olein frying oil added with threadfin bream (TFB) hydrolysate and Nanox 189 were studied. The DPPH radical scavenging activities and chelating effects of ferrous ion were evaluated and compared with α-tocopherol. Oxidative stability after 30 frying cycles were analysed for induction period, free fatty acids (FFA), peroxide values (PV), total polar compounds (TPC) and viscosity. Palm olein without any antioxidant were used as control. Nanox 189 exhibited higher percentage on DPPH scavenging effect and ferrous ion chelating effect than TFB hydrolysate. Frying oil added with Nanox 189 recorded the longest induction period which was up to 11 hr. while TFB hydrolysate added oil showed induction period of 9 hr. Nanox 189 addition in frying oil yielded the lowest FFA and PV followed by those added with TFB hydrolysate. Highest readings of TPC was recorded for TFB hydrolysate added oil which is 13%. Throughout the 30 frying cycles, the addition of TFB hydrolysate recorded lower percentage increase for viscosity than Nanox 189 with 4.7% compared to the latter which is 9.6%. Even though the antioxidant activities of TFB hydrolysate was lower than that of Nanox 189, the study suggested some antioxidant potential of TFB hydrolysate based on the DPPH radical scavenging activities and chelating effects of ferrous ion as well as its ability to slightly improve the oxidative stability of palm olein during the 30 frying cycles.

Published: August 2020

Non-destructive testing (NDT) is a method of testing and analysis that relies on the application of physical principles to determine the integrity of materials without causing damage. The existence of weld discontinuity can affect the service ability of the structures. Ultrasonic testing Phases Array (UTPA) is advanced ultrasonic testing technology widely practiced in many industries. The multiple ultrasonic elements and electronic time delay will create constructive and destructive interference and steering capability, which could improve detectability compared to a single element of conventional UT. The multi displays presented in A-Scan, S-scan, B-Scan, and C-Scan of UTPA equipment capable of locating, inspecting, and characterise defects within the welded component. Two carbon steel plates with thickness 18 mm and 24 mm were prepared and cut to V-shape configuration and welded using shielded metal arc welding (SMAW) process, labelled as NDE-8826 and NDE-8827 respectively. Both samples were induced with artificial defects of the weld. 16 elements of phased array probe with 0.5 mm pitch and 4 MHz were carried out for this study with encoded scanning to identify weld discontinuity plotted in different types of UT displays. Additional testing was performed using conventional ultrasonic testing (UT) using a 4 MHz probe to compare with the UTPA results and the acceptability of each defect detections. The length and datum of toe crack, slag, and lack of inter run fusion detected by UTPA in NDE-8826 give the same value as the actual value. However, the localisation of the defect is slightly different at 1.0 mm for UT detection. While the detection value for slag gives the same values for UT and UTPA, which also the same as the actual values. The detection of lack of penetration and lack of fusion in sample NDE-8827 was precisely can be detected by UT and UTPA; hence their datum value has slightly different in the centerline crack and porosity at 2.0 mm for UT measurement, and as for UTPA, it was found that the porosity at 3.0 mm which higher value compared to the actual value, 250 mm. From the result, a relevant indication from the UTPA and conventional UT collected it was found that the UTPA technique is capable of improving the Probability of Detection (POD) of defects compared to the conventional UT.

Drinking-Water Company (PAM) Jaya as a regional company is responsible for supply clean water in DKI Jakarta, is demanded to conduct partnerships with the private sector, namely PT Palyja and PT Aetra Air Jakarta. After the partnership, there are still many people who do not have access to clean water services. The purpose of this study is to find out and analyze the implementation of the Public-Private Partnership implemented by PAM Jaya and private partners in the supply of clean water in DKI Jakarta. The research method used qualitative research methods.  The theory used is the utilization of the Public-Private Partnership proposed by Emanual Savas (2000) which consists of roles and functions, competition, regulation, risk, procurement, and financing. The results of this study the implementation of the Public-Private Partnership in the supply of clean water in DKI Jakarta has not been effective because of the failure to fully utilize the Public-Private Partnership. The absence of competition and procurement processes between partners, the absence of regulations referred to so that the impact on the Cooperation Agreement (PKS) did not reflect public interests. There were roles and functions of PAM Jaya and private partners that were not conducted, unclear risk-sharing and compensation to private partners were more giving loss to the PAM Jaya, resulting in a shortfall. The author suggests that the PKS contract is needed, also the Provincial Government of DKI Jakarta needs to issue strict and clear regulations, improve services to the public, and no longer use the form of concession cooperation.

This study was titled "Implementation of Billboard Tax Policy in the City of Bandung". This study was backed by the writer's interest in seeing the phenomenon of unachieved billboard tax revenue targets for the past few years, even the realization is below 11% of the target that was set in the City of Bandung. The purpose of this study was to find out and analyze the billboard tax policy implementation in the City of Bandung. This study applied the theory of Soren C. Winter that explains three factors that influence the process of policy implementation. This research used a qualitative research method.              The results showed that the implementation of the tax policy billboard in the city of Bandung had gone well but there were still obstacles in organizational and inter-organizational behavior, caused by the lack of coordination that existed between BPPD and Satpol PP. Furthermore, the behavior of the target group was also found that there were still negative responses from billboard organizers who are looking for loopholes so they can be detached from the imposition of billboard taxes. Meanwhile, on the other aspects, it had gone well, such as the street-level bureaucrat's behavior, namely through discretion which was done by making barcodes and working fast without waiting for recommendations from other SKPD to supervise billboards that are considered to be in violation. The commitment indicators of organizational and inter-organizational behavior have gone well because employees' actions were in line with the vision and mission of the organization and the last indicator of positive response to the behavior of the target group can be seen from the support of billboard organizers to help the government supervise and remind the public to be obedient on paying taxes.

Published: August 2020

— The consumption of sprouts in the human diet has grown during the last years, but great concern raised from public health institutions, food industry and consumers regarding their safety since foodborne diseases caused by microorganisms have been reported. Copper metal as a contact surface was studied during the germination of alfalfa seeds (Medicago sativa L.) inside a rotating drum on a laboratory scale and compared with a plastic surface of food-grade. A system of three rotating drums was used inside a thermo-regulated chamber to germinate seeds. To evaluate the antibacterial activity of copper sheets, alfalfa seeds were inoculated with 4.2 log cfu g-1 of Escherichia coli and after 84 hours of germination sprouts were evaluated for E. coli, mesophilic aerobic bacteria, the content of copper and other minerals (potassium, calcium, magnesium, sodium, iron, manganese, and zinc), total mass, unit mass and length, and color. The contact of alfalfa sprouts with copper sheets allowed to reduce the E. coli load from 6.54 to <0.1 log cfu g-1. However, all sprouts exceeded in copper (> 10 ppm) according to Food Sanitary Regulations. Germinated mass and length decreased after copper treatments. No statistically significant differences were observed between treatments for the remaining quality parameters. Finally, it is concluded that copper was very efficient in reducing the microbial load of E. coli in alfalfa sprouts, complying with the regulations established by the Chilean Ministry of Health.

Published: August 2020

Tricuspid regurgitation, either isolated or associated with left-valve disease, has a strong impact on outcome. Surgical treatment of tricuspid regurgitation has increased in recent years, but in-hospital mortality remains high probably due to the risk profile of the recipients. As a consequence, most of the patients with severe tricuspid regurgitation, especially if isolated, remain untreated. Transcatheter tricuspid valve interventions are rapidly spreading as alternative options to open-heart procedures fulfilling this important unmet need. Although patient selection and timing of intervention are unclear, many devices have been developed in recent years for both repair and replacement of tricuspid valve. Repair tools can be targeted to leaflets or annulus. Replacement devices include heterotopic and orthotropic systems. The aim of this review is to report possible indications and summarize current data about the different devices available for transcatheter tricuspid valve interventions.

The coronavirus disease 2019 (COVID-19) has important implications for the cardiovascular care of patients. COVID-19 interacts with the cardiovascular system on multiple levels, increasing morbidity in patients with underlying cardiovascular conditions and favoring acute myocardial injury and dysfunction. COVID-19 infection may also have long-term implications for overall cardiovascular health. Many issues regarding the involvement of the cardiovascular system remain controversial. Despite angiotensin-converting enzyme 2 serving as the site of entry of the virus into the cells, the role of angiotensin-converting enzyme inhibitors or AT1 blockers requires further investigation. Therapies under investigation for COVID-19 may have cardiovascular side effects. Treatment of COVID-19, especially the use of antivirals, must be closely monitored. This article is a review of the most updated literature.

Background and aims

Previous studies showed that troponin blood levels may increase after exercise. In this study, we assessed whether, among patients with suspected of having stable angina, the increase in troponin I (TnI) levels after exercise stress test (EST) might help identify those with obstructive coronary artery disease (CAD) and myocardial ischemia.

Methods

We performed maximal treadmill EST in 50 patients (age 64 ± 9 years; 38 men) admitted to our Cardiology Department to undergo elective coronary angiography because of a suspicion of stable angina. TnI was measured before and 12 h after EST.

Results

TnI increased after EST compared with baseline in the whole population (from 0.44 ± 0.76 to 0.84 ± 1.12 ng/dl, P < 0.001). No difference in TnI increase was observed between patients with obstructive CAD (n = 29; 0.61 ± 0.90–1.13 ± 1.33 ng/dl) and no obstructive CAD (NO-CAD; n = 21; 0.21 ± 0.46–0.44 ± 0.54 ng/dl; P = 0.51). There was also no significant difference in post-EST TnI increase between patients with positive EST (n = 34; 0.56 ± 0.89–1.05 ± 1.28 ng/dl) or negative EST (n = 16; 0.19 ± 0.26–0.39 ± 0.43 ng/dl; P = 0.16). Moreover, no significant difference was observed in the post-EST TnI increase among groups of patients with positive EST and obstructive CAD, positive EST and NO-CAD, negative EST and obstructive CAD and negative EST and NO-CAD (P = 0.12). No clinical or EST variable was associated with post-EST TnI increase, although there was a tendency for a greater increase in those achieving a heart rate more than 85 vs. less than 85% of maximal predicted heart rate during EST (P = 0.075).

Conclusion

TnI increase after EST in patients with suspected stable angina is largely independent of the results of coronary angiography and EST.

OBJECTIVE

To examine the association between prerace administration of phenylbutazone and the risk of musculoskeletal injury (MSI) and fatal injury in Thoroughbred racehorses that raced between 2006 and 2015 at 2 of the 4 official racetracks in Argentina.

SAMPLE

Data from racetrack databases and veterinary reports on 283,193 race starts.

PROCEDURES

Data were collected relating to race performance and injury outcomes for starts at these tracks. The incidence of MSI and fatal injury was calculated for each year, stratified by the declared prerace administration of phenylbutazone. Univariable logistic regression, followed by multivariable logistic regression, was used to identify significant risk factors for both MSI and fatal injury.

RESULTS

Analyses identified associations between the declared prerace administration of phenylbutazone and the risk of MSI and fatal injury during racing. Horses with declared prerace phenylbutazone administration had greater odds of MSI (OR, 1.45 [95% CI, 1.03 to 2.04]) and fatal injury (OR, 1.59 [95% CI, 1.1 to 2.27]) than did horses racing without prerace phenylbutazone administration. These associations remained significant when other risk factors were accounted for in both multivariable models.

CONCLUSIONS AND CLINICAL RELEVANCE

Results suggested an association between the prerace administration of phenylbutazone and the risk of MSI and fatal injury in Thoroughbred racehorses during racing. Although these results did not imply a direct causal relationship between prerace phenylbutazone administration and injury, they may be considered in the development of more conservative medication policies to optimize racehorse welfare in North and Latin America.

Radiological diagnostics serves as one of the basic monitoring techniques in veterinary dental practice. The recent up-to-date literature data based on the findings of digital radiology/radiovisiography (RVG) in general dentistry inspired the authors to present its possible use in clinical veterinary dentistry. The digital radiography used in this study was RVG Trophy Radiologie SA 2001 device equipped with software for linear measurements (readings), densitometry, setting of contrast of radiography image, 3D image manipulation, zooming of detail and orientation handling. The aim of the study was to evaluate the bone mineral density of the alveolar part of the lower jaw in seven Scottish terriers. Bone mineral density measurement was performed around the central lower incisors by converting gray scale values into equivalent aluminum thickness (mm Al). The mean bone mineral density was in the range of 4.31-6.20 mm Al with no significant statistical difference between left and right incisors (p>0.01). Our results showed that the combination of RVG and aluminum step wedge etalon is a reliable tool to measure bone mineral density around the lower central incisors in dogs. This method can be considered as comfortable for manipulation in everyday use in clinical veterinary practice.

The features of magneto-abrasive machining of taps for metric thread cutting were investigated. The calculation method of integral intensity of the magneto-abrasive machining of the working surfaces of the taps by the quantitative values of normal and tangential components of moving speed of the quasi-stable volumes of the magneto-abrasive tool was developed. Based on the results of calculations, it was possible to predict the probable influence of the taps’ location in the working zone on the quality and efficiency of machining their working surfaces. The calculation method is relevant for taps of all diameters with a profile angle of 60°. The working surfaces of the tool would not be effectively machined if the location angle of taps to the plane of the working zone of the machine equals 20–60°. Depending on the expected major polishing or strengthening effect of magneto-abrasive machining, the taps are required to be located at an angle of 60–90° to the plane of the working zone of the machine.

Published: August 2020

In recent years, there has been a growing interest in alternative sources of power supply for internal combustion engines. Liquefied petroleum gas injection systems are among the most popular. It becomes necessary to know mathematical descriptions of the operation of individual components. The article presents a mathematical model that describes the operation of the low-pressure gas injector. Valtek plunger injector was chosen as the test object. The mathematical description includes three parts, i.e. electric, mechanical and pneumatic. The electrical part describes the generation of electromagnetic force by a circuit with a coil, in the mechanical equilibrium equation of forces acting on the plunger, and in the pneumatic part the air pressure on the plunger. The calculations were performed in the Matlab/Simulink environment, creating current waveforms, acting forces and plunger displacement. Correctness of mathematical description and determined in the course of opening and closing time calculations were related to the values declared by the manufacturer, showing differences below 3%. The presented mathematical model can be modified for other injector design solutions.
Natural Convection from Four Circular Cylinders in Across Arrangement within Horizontal Annular Space
Authors: Laidoudi Houssem
Published: August 2020

Numerical investigation is accomplished to study the roles of governing parameters of natural convection on the fluid motion and heat transfer rate of four heated circular cylinders placed inside a circular enclosure of cold surface. The cylinders are positioned in across arrangement. The representative results are obtained within the ranges of initial conditions as: Prandtl number (Pr = 7.1 to 1000) and Rayleigh number (Ra = 103 to 105). The average Nusselt number of each inner cylinder is computed. The effects of thermal buoyancy strength on the fluid motion and temperature are also illustrated. It was found that the heat transfer rate of cylinders depends significantly on the position inside the enclosure. Moreover, the role of Prandtl number on flow and thermal patterns is negligible. The values of Nusselt number are also given, which can be useful for some engineering applications.

Authors: Negrea Mihai Octavian , Neamțu Mihai Leonida
Published: August 2020

The link between obesity and a wide range of cardiovascular disorders is well known.(1,2) In recent years, the prevalence of obesity has reached an alarming level.(3) Unfortunately, the situation is similar for the paediatric population – which may provide a perspective on the continuously growing global burden of this affliction.(4) Acting upon this issue is a fundamental direction in modern preventive medicine. A firm action starting in childhood may prove itself to be more beneficial the sooner it is implemented. Multiple anthropometric, clinical, laboratory and imaging parameters have been related to the presence of obesity and cardiovascular risk. This article represents a proposal for a possible protocol of a study aimed at paediatric obesity as a cardiovascular risk factor and aims to construct a model for a therapeutic intervention in these patients.
