Developing Data Integrity in an Electronic Health Record System using Blockchain and InterPlanetary File System (Case Study: COVID-19 Data)
Authors: Riadi Imam , Ahmad Tohari , Sarno Riyanarto , Purwono Purwono , Ma'arif Alfian
Published: February 2022

The misuse of health data stored in the Electronic Health Record (EHR) system can be uncontrolled. For example, mishandling of privacy and data security related to Corona Virus Disease-19 (COVID-19), containing patient diagnosis and vaccine certificate in Indonesia. We propose a system framework design by utilizing the InterPlanetary File System (IPFS) and Blockchain technology to overcome this problem. The IPFS environment supports a large data storage with a distributed network powered by Ethereum blockchain. The combination of this technology allows data stored in the EHR to be secure and available at any time. All data are secured with a blockchain cryptographic algorithm and can only be accessed using a user's private key. System testing evaluates the mechanism and process of storing and accessing data from 346 computers connected to the IPFS network and Blockchain by considering several parameters, such as gas unit, CPU load, network latency, and bandwidth used. The obtained results show that 135205 gas units are used in each transaction based on the tests. The average execution speed ranges from 12.98 to 14.08 GHz, 26 KB/s is used for incoming, and 4 KB/s is for outgoing bandwidth. Our contribution is in designing a blockchain-based decentralized EHR system by maximizing the use of private keys as an access right to maintain the integrity of COVID-19 diagnosis and certificate data. We also provide alternative storage using a distributed IPFS to maintain data availability at all times as a solution to the problem of traditional cloud storage, which often ignores data availability. Doi: 10.28991/esj-2021-SP1-013 Full Text: PDF

Authors: TRAK Diğdem , ARSLAN Yasin
Published: January 2022

AuNPs are being conventionally synthesized by traditional methods (physical and/or chemical) with preferred and well-defined morphology, size and shape. On the other hand, it has been reported that these methods involve difficult reaction conditions and/or toxic chemicals. In this study, an easy, cost effective and more environmentally and biological-friendly method was described for the synthesis of gold nanoparticles with Dimrit raisin extract for the first time. The effects of some experimental parameters, such as concentrations of both raisin extracts and Au solutions, synthesis time and synthesis temperature were investigated for the synthesis of AuNPs. The synthesized AuNPs were extensively characterized by UV-Visible spectrometer, Transmission electron microscopy (TEM), X-ray diffraction patterns (XRD) and Fourier transform–infrared spectroscopy (FTIR). TEM results show spherical along with triangular and hexagonal shaped nanoparticles with an average size of 15 nm. Large amounts of toxic dyes are used in the different industrial area and dyes posed a threat for water sources. Therefore, it has become imperative to develop inexpensive and environmentally friendly methods to remove dyes from water. In recent years, degradation using green synthesized nanoparticles has become an efficient method to remove dyes from the water sources. In this study, the catalytic activity of the AuNPs for the degradation of both methylene blue (MB) and methyl orange (MO) dyes were also studied and AuNPs behaved as effective catalysts for both degradations of MB and MO dyes in terms of percentage removal and kinetics. The experiment results showed that AuNPs can be employed as strong candidate in wastewater treatment studies.

Published: January 2022

Sustainable marine spatial planning in small islands requires a more comprehensive management strategy. Unsustainable use problems and issues in both land and seascape need a strategic formulation to manage Tiworo Small Island in the future. This study aimed to formulate the strategy for sustainable marine spatial planning of the Tiworo Small Islands. The rapid Appraisal for Land Use (Raplanduse) method was used to assess the sustainability and sensitivity of the attributes used in this study. The formulation of management strategies was carried out based on the levels of influence and dependence on sensitive attributes analyzed by the prospective analysis method. The results showed that the sustainable use of small islands in the Tiworo Islands varied, ranging from good, bad to less sustainable. Sensitive attributes observed in the ecological dimension were suspended solid materials and seawater surface temperature. In the social dimension, the sensitive attributes assessed were the conflict incidence among residents and human resources. Attributes observed in the economic dimension were income level, availability of business capital, and fisheries catch production. In the legal and institutional dimensions, the sensitive attributes observed were land ownership status and area zoning. Strategic management was developed based on these sensitive attributes, including increasing community adaptation capacity, controlling land-use in watershed areas in the mainland, developing business diversification, regulating spatial utilization, and improving the quality of human resources.

Published: January 2022

Makassar Strait plays a vital role as one of the skipjack tuna fishing grounds in Indonesia. This study aimed to detect the skipjack tuna preference of sea surface temperature (SST) and chlorophyll-a (Chl-a) in Makassar Strait and to map out the possible shifting potential fishing zone (PFZ) of skipjack tuna by simulating sea surface temperature increase. We analyzed the skipjack catch data from July to November 2020, and we added the previous data in June, July, August, October, and December 2019 in the same study area. We analyzed together with satellite imagery data set of SST and Chl-a using GAM. We used three scenarios for the SST increase model simulation, which are 0.25, 0.5, and 1℃. The results showed that skipjack tuna is relatively high in SST ranging from 28.3 to 30.4°C and Chl-a ranging from 0.18 to 0.28 mg/m3. The PFZ based on sea surface temperature simulation showed that PFZ area form in the northern part shifting to the southern part of Makassar Strait based on the increasing sea surface temperature simulation visible in September, which shifted from 0.017-5.421⁰S to 2.923-6.802⁰S and October shifted from 0.017-6.802⁰S to 5.007-6.802⁰S. Knowing the shifting of the potential fishing zone of skipjack tuna could be an important step toward fishing operation and management for skipjack tuna resource management in Makassar Strait.

Mangrove merupakan ekosistem pesisir yang memiliki kemampuan sangat baik dalam menyerap dan menyimpan karbon. Struktur tegakan mangrove memberikan kontribusi signifikan terhadap estimasi simpanan karbon yang umumnya tergambarkan pada persamaan alometrik dalam skala individu. Penelitian simpanan karbon atas permukaan tanah (abovegroundada komunitas mangrove telah dilakukan di mangrove Teluk Benoa. Penelitian ini bertujuan untuk membangun model dalam mengestimasi simpanan karbon aboveground dari beberapa parameter struktur tegakan mangrove. Metode stratified purposive sampling digunakan dalam penentuan sebaran titik penelitian. Sebanyak tiga zona (1–3) diidentifikasi berdasarkan interpretasi analisis mRE-SR (modified red edge-simple ratio) dan jenis mangrove yang mendominasi. Estimasi simpanan karbon aboveground diperoleh dengan metode non-destructive menggunakan persamaan common allometric. Hasil penelitian menunjukkan struktur tegakan mangrove zona 1 cenderung berbeda signifikan dengan zona lainnya. Secara keseluruhan, rata-rata simpanan karbon aboveground sebesar 193,45±34,88 ton C/ha. Simpanan karbon aboveground tertinggi ditemukan pada zona 1 yang didominasi jenis Sonneratia alba. Analisis regresi linear dan Akaike’s Information Criterion (AIC) menunjukkan bahwa kombinasi dari tutupan kanopi, kerapatan pohon, kerapatan pancang dan diameter pohon menjadi model terbaik dalam mengestimasi simpanan karbon pada skala komunitas. Model kombinasi ini memiliki nilai koefisien regresi tertinggi dan nilai root mean squared error (RMSE) terendah dibandingkan dengan model lainnya. Hasil penelitian diharapkan dapat digunakan dalam mengestimasi simpanan karbon secara lebih efisien dan akurat dalam skala komunitas.

The existence of reef fish is certainly closely related to the existence of reefs coral because the ecosystem is a habitat for reef fish. Coral reefs are ecosystems that are commonly found on small islands in the tropics including the Seribu Islands. The Seribu Islands are a group of 110 islands located off the coast of Jakarta and up to 80 kilometers north of the Java Sea. In this study, we examined the species distribution and diversity of reef fish species on two different distance location in Jakarta Bay using environmental DNA (eDNA) metabarcoding analysis from two sites which are Untung Jawa Island and Harapan Island. The 4L eDNA seawater samples were collected at a depth of 8-9 meters at each site and then analysis using specific primer (MiFish U) of 12S rRNA. Overall, the higher species richness was found on Harapan Island (52 species) followed by Untung Jawa Island (11 species). The Shannon-Wiener Index also showed Harapan Island has higher reef fish diversity based on three taxonomic level (family, genus, and species). There were only five mutual reef fish species found in the two locations, namely Atherinomorus aetholepis, Auxis thazard, Cephalopholis sexmaculata, Epinephelus chlorostigma, and Plectropomus areolatus. The results of these findings in this current study are in line with anthropogenic pressure different where Untung Jawa Island is the closer one to Jakarta Bay than the Harapan Island that located relatively far from Jakarta Bay.

Mangrove merupakan salah satu ekosistem pesisir yang utama, jika ekosistem mangrove rusak maka akan berdampak merugikan bagi manusia dan habitat sekitarnya. Penelitian ini membahas 3 (tiga) hal, (1) fenomena deforestasi hutan pada periode 1972–2013 di Tanakeke, (2) potensi deforestasi tutupan lahan mangrove di pulau Tanakeke, (3) kelembagaan konsep yang terjadi di Pulau Tanakeke selama periode 1972-2013. Data yang digunakan dalam penelitian ini adalah data sekunder yang diperoleh dari hasil penelitian sebelumnya (1972-2019). Metode analisis yang digunakan adalah studi literatur, pengujian indikator dari penelitian sebelumnya, depth interview, dan analisis data kuantitatif dan kualitatif. Hasil penelitian ini menunjukkan konversi lahan ekosistem mangrove secara masif telah terjadi sejak tahun 1972-1993 yang berimplikasi pada penurunan luas mangrove yang mencapai 1.166,61 ha. Sedangkan dari tahun 1993-2013, luas tutupan hutan mangrove yang hilang akibat alih fungsi lahan mangrove menjadi tambak mencapai 32,25% dalam kurun waktu 20 tahun. Deforestasi yang terjadi di Pulau Tanakeke mengakibatkan kerusakan lingkungan. Fenomena kerusakan mangrove mendorong beberapa institusi untuk memotivasi keterlibatan langsung masyarakat pulau Tanakeke untuk membentuk kelembagaan dan kebijakan dalam menjaga kelestarian ekosistem mangrove.

Simeulue Regency is surrounded by small islands rich in diverse fish resources, namely dogtooth tuna. The interaction (reciprocity) between groups of organisms and their environment plays an important role in ecological systems. The determination of ecological status can be used to monitor, manage, and sustain waters in tuna fishing areas. Fishing activities will affect environmental changes that will impact marine biota's sustainability, existence, and diversity. This study aimed to analyze the ecological sustainability status of tuna fishing areas in East Simeulue waters. The research was conducted in May-July 2021. The method used in this research was observing and measuring the characteristics of the aquatic environment and conducting interviews.

THE INFLUENCES OF ADHERENCE TO TAMOXIFEN AND CYP2D6 PHARMACOGENETICS ON PLASMA CONCENTRATIONS OF THE ACTIVE METABOLITE (Z)-ENDOXIFEN IN BREAST CANCER
Authors: Rocha José Claudio Casali da
Published: February 2022

Tamoxifen efficacy in breast cancer is suspected to depend on adherence and intact drug metabolism. We evaluated the role of adherence behavior and pharmacogenetics on the formation rate of (Z)-endoxifen. In 192 Brazilian patients, we assessed plasma levels of tamoxifen and its metabolites at 3, 6, and 12 months of treatment (LC-MS/MS), adherence behavior (Morisky Medication Adherence Scale), and CYP2D6 and other pharmacogene polymorphisms (MALDI-TOF mass spectrometry and real-time PCR). Adherence explained 47% of the variability of tamoxifen plasma concentrations (p<0.001). While CYP2D6 alone explained 26.4%, the combination with adherence explained 40% of (Z)-endoxifen variability at 12 months (p<0.001). The influence of low adherence not to achieving relevant (Z)-endoxifen levels was the highest in patients with non-compromised CYP2D6 function (RR 3.65, 95%CI 1.48–8.99). As a proof-of-concept, we demonstrated that (Z)-endoxifen levels are influenced by patient adherence to both tamoxifen and CYP2D6, which is particularly relevant for patients with full CYP2D6 function.

Introduction: Breast cancer is the most common cancer in women worldwide, whose treatment is increasingly effective with survival above 90% in initial tumors, while it ranges from 20% to 40.8% in metastatic tumors. However, metastatic breast cancer persists and the survival of these women and treatments remain a challenge for oncology. Objective: To analyze the prognostic factors associated with the survival of patients with metastatic de novo breast cancer. Material and Methods: This is a retrospective cohort of women with stage IV (metastatic) breast cancer, conducted from January 1, 2000 to 31 December 2012, treated at the AC Camargo Cancer Center. The overall 5-year survival (OS) by using the Kaplan– Meier product-limit estimator and the differences between the curves and Cox multiple regression by using log-Rank method were observed. Results: Out of 265 patients analyzed, 182 (68.7 %) were alive at the end of the follow-up. The 5-year survival rate was 29.9%. There was a significant difference in survival rates, according to the categorized age (≤50 years, 51–70 years, and ≥71 years; p<0.046), primary breast tumor surgery (mastectomy and quadrantectomy; p<0.001), exclusive hormone therapy or multimodal treatment (p<0.088), treatment initiation period 2000–2005 and 2006–2012 (p<0.004), education, where the greater the school degree, the greater the survival (p<0.001), and luminal tumors (p<0.003). In multiple regression, surgery (p=0.001), chemotherapy (p=0.038), hormone therapy (p<0.001), luminal tumors (p=0.03), having HER2 tumor and using target therapy (p=0.001) and have been treated in the period from 2006 to 2012 (p=0.043) remained as predictive factors for a better prognosis. Conclusion: Patients undergoing resection of the primary tumor had longer survival and better prognosis.

An information system is a collection of data or facts that are processed and processed in such a way as to produce something that can be understood and can be useful for the recipient. Among the general public, the need for accurate and fast information is urgently needed at this time, especially information regarding the spread of the Covid-19 disease that is hitting the world today. Covid-19 (Coronavirus) is a virus that can attack the respiratory tract and can be transmitted to anyone through droplets of phlegm. However, in conveying information by the Kerongkong Health Center officers regarding the Covid-19 distribution area in the Suralaga sub-district, they still use the socialization method. This method is considered right on target, but it is considered less effective for villages that have a fairly high distribution rate in the Suralaga sub-district. Therefore, an information system for Mapping the Covid-19 Spread Area is needed that is fast and accurate in conveying information to the public, the goal is to make it easier for the puskesmas to take preventive actions against areas that have a fairly high spread rate by looking at the location of the distribution area in the sub-district. suralaga. WebGIS is a web-based geographic information system consisting of several components, namely mapping graphic design, digital maps with geographic analysis, computer programs, and a database that are interconnected into one part. In the preparation of the stages of this research carried out by means of data collection, system design, system creation stage, testing and evaluation. The existence of WebGIS mapping the patient's location can help the throat health center in collecting data on Covid-19 patients and can quickly provide information to the public.
