The representative from the Consul General is Mr. Ishii Yutaka as Deputy Consul General of Japan Surabaya and Prof. Toshimasa Nishiyama, MD & DMSc as professor and chairman of Kanzai Medical University. They were welcomed by the chairman Prof. Maria Inge Lusida, Ph.D., Deputy ITD Prof. Fedik Abdul Rantam, Prof. Soetjipto, Prof. Kazufumi Shimizu, Prof. Sri Subekti and representative researchers from the Dengue, Entomology and Avian Influenza laboratories. In this meeting, an introduction was made to each institution starting from Kanzai Medical University which was continued by ITD UNAIR presentations. In this case, Prof. Toshimasa Nishiyama, MD & DMSc explained what things are owned and all the activities that exist at Kanzai Medical University, he also explained that they would be open to giving students the opportunity to take part in a 4-year doctoral scholarship program there. Not only that, he also explained about the research and collaboration that had been carried out by Kanzai Medical University. From this explanation, parties from ITD UNAIR were very interested in considering and deciding on future collaboration. The hope is that ITD UNAIR can collaborate with more foreign parties to be able to develop the world of research, especially in the world of health for all foreign countries in the future.

January 19, 2023, the Tropical Disease Institute received a visit from the Airlangga University Faculty of Medicine student organization (CIMSA). This visit consisted of foreign students from the Faculdade Ciências Médicas de Minas Gerais Brazil and the Faculty of Medicine, Airlangga University, this visit saw activities in several laboratories such as Human Genetics, Avian Influenza, Natural Products (NPMRD), and gastroenterology. it is hoped that this visit will be able to share information related to activities, collaboration, and research that is being developed at the Institute for Tropical Diseases which can later become an attraction for foreign researchers so that collaboration can be created later.

Universitas Airlangga held an archive exhibition of Covid-19 pandemic at Surabaya Alun-Alun Youth Center on Tuesday, January 3, 2023. The exhibition presents archives of policy documents, photos and videos that describe UNAIR’s efforts to deal with the Covid-19 pandemic, facilities and innovations made during the pandemic. UNAIR Secretary Dr Koko Srimulyo Drs MSi said that the Covid-19 pandemic archive exhibition aims to store documentation of Covid-19 handling in Indonesia. So that future generations can study and deal with similar outbreaks better. Koko also hopes that there will be a Covid-19 museum in Indonesia to collect and store better documentation of Covid-19 in Indonesia. He said that the Covid-19 archive exhibition was a trigger for UNAIR to build a museum about Covid. “Because in Indonesia there is no museum about Covid. Perhaps the idea of ​​a museum about Covid is the first in Indonesia. The Indonesian government should build a museum about Covid-19 like this,” he said. Meanwhile, UNAIR Vice Rector for Research, Innovation, and Community Development, Prof Dr Ni Nyoman Tri Puspaningsih MSi said that in the exhibition showcased three kinds of archives: Covid-19 handling at the forefront, treatment of infected people, and the handling of the deceased as a result of Covid-19. “So I think that all archiving activities are complete, from the beginning to the end, from those who have recovered to those who cannot be saved. And awards, photos, and videos,” she said. Prof Nyoman also explained that UNAIR had sent 1,225,000 doses of Inavac vaccine to the Ministry of Health, which were ready for use for adults. However, they are still waiting for BPOM examination. “Now every batch of vaccine products is checked by BPOM, even though they have received an EUA (Emergency Use Authorization) it does not mean they are distributed immediately. But it is checked again so that unwanted residue does not occur, if it is safe, it is distributed,” she said. Prof Nyoman added that the Inavac vaccine was ready to be distributed to 34 provinces. She hopes that East Java will get some of the vaccine doses. (*) Author: Muhammad Mu’afa Rahman Editor: Binti Q.

The Coronavirus Disease (COVID-19), caused by the novel coronavirus was detected in December 2019 in Wuhan, China for the first time and quickly spread into a global pandemic. This study aims to predict the potential of macroalgae bioactive compounds as SARS-CoV-2 antivirals by inhibiting the ACE2 receptor through an in silico approach. Twenty-seven macroalgal compounds were obtained from PubChem (NCBI, USA), while the target protein ACE2 receptor was collected from the Protein Data Bank (PDB). Then the drug similarity screening was carried out using Lipinski’s rules from five web servers and prediction of bioactive compounds was carried out using PASS (predicted activity spectrum for biologically active substances) via an online web server. After the compound was approved by Lipinski’s five rule and PASS online prediction web server, blind docking simulations were performed with PyRx 0.8 software to show the binding energy values. Molecular interaction analysis was performed with BIOVIA Discovery Studio 2016 v16.1.0 and PyMOL v2.4.1 software. There are six macroalgae compounds approved by Lipinski rules and PASS Analysis Online. The result was that the macroalgae siphonaxanthin among 27 macroalgae compounds showed a strong binding energy to bind to the ACE2 receptor with a value of -8.8 kcal/mol. This study also used SARS-CoV-2 drugs as positive controls, namely remdesivir, molnupiravir, baricitinib, lopinavir, oseltamivir, and favipiravir. The results showed that siphonaxanthin had the lowest binding energy compared to common drugs SARS-CoV-2. Macroalgae compounds are predicted to have potential as SARS-CoV-2 antivirals. Thus, further studies need to be investigated with in vitro and in vivo analyzes to confirm the inhibitory activity of siphonaxanthin against SARS-CoV-2.

{:en}Tuberculosis (TB) and Corona Virus Disease (COVID-19) are infectious diseases that infect the respiratory tract. Tuberculosis is caused by Mycobacterium tuberculosis while COVID-19 is caused by SARS CoV-2. Transmission of the disease is through coughing, sneezing and close contact with infected individuals. Tuberculosis disease has spread throughout the world and it is reported that Indonesia is ranked second in the world (543,874 cases), so, serious attention is needed by various sectors to suppress the transmission and elimination of this disease. During the COVID-19 pandemic during the last two years there were indications of COVID-19 coinfection in pulmonary tuberculosis patients, this was due to the risk and severity caused by COVID-19 disease and the high risk of death due to the development of new diseases in TB patients. Data released by the Ministry of Health of the Republic of Indonesia related to the development of TB cases shows a fluctuating trend over the past decade. In 2020, the incidence of TB cases in Indonesia increased to 845,000 with a mortality of more than 98,000 people. Furthermore, in 2021 there was a decline in cases reaching 2.04% from the previous year as many as 393,323 cases as a result of the government’s attention being focused on reducing the incidence of COVID-19. However, WHO determined that Indonesia urgently needed to carry out epidemiological surveillance of TB disease during the COVID-19 pandemic, this was due to a decrease in monthly and quarterly TB notifications and the first half of 2021 substantially decreased from 2019 in most countries with the highest TB burden. . Reportedly, a relative reduction in annual notifications between 2019 and 2020 was seen in Gabon (80%), the Philippines (37%), Lesotho (35%), Indonesia (31%) and India (25%) so that the real number of TB cases is estimated much higher than those found and treated and a decline in 2021 presumably many cases go unreported. Taking into account the updated information released by the World Health Organization, secondary data-based epidemiological surveillance was carried out by utilizing regional data reports released annually. The data used is the number of confirmed cases of positive TB and COVID-19 in the East Java Province and compared with each other with other factors or determinants. Geographical mapping of the distribution of cases of tuberculosis and COVID-19 was also carried out using the Quantum Geographic Information System (QGIS) to identify areas that have the potential to have the highest level of risk and severity of these two diseases. There are several indicators that are reviewed for the correlation between these two diseases, including: the correlation between the incidence and mortality rates of tuberculosis and COVID-19 cases, the relationship between case cure rates and death rates for tuberculosis cases, the incidence and success rates of tuberculosis treatment, the correlation between treatment success rates. and the death rate of tuberculosis cases, the rate of case recovery, and the death rate of COVID-19 cases as well as the calculation of geographical factors including the ratio of puskesmas, the number of doctors, nurses, midwives, public health workers, environmental health workers, nutritionists, and pharmacists and all ratios are calculated per 100,000 inhabitants. The results of the study obtained that the incidence of tuberculosis in East Java Province in 2020 was 95.49/100,000 population with varying case cure rates. TB cases are dominated by the male sex community. The number of women in East Java in 2020 reached 20,374,104, while men reached 20,291,592. The population with tuberculosis which is dominated by women is only found in Probolinggo district with a higher number of women (604) than men (561). Furthermore, the highest infection rate was found in Madiun (296.51/100,000 population), while the lowest was in Malang (0.07/100,000 population). The incidence ratio of tuberculosis cases based on gender was found for men (117.66/100,000 people) higher than women (93.49/100,000 people). The district with the highest incidence of tuberculosis in males is Madiun (342.62/100,000 population) and the lowest is Pacitan (57.88/100,000 population). Furthermore, in the female gender, the highest incidence of tuberculosis was in Pasuruan (223.16/100,000 people) and the lowest was in Pacitan (93.49/100,000 people). Based on the findings, the highest incidence of COVID-19 infection was found in Mojokerto (789.9/100,000 population), while the lowest was found in Sampang (52.5/100,000 population). Analysis by gender found that the incidence of COVID-19 in women (210.74/100,000 population) was higher than that of men (198.04/100,000 population). Meanwhile, the regency with the highest male population is in Mojokerto (744.46/100,000 people), while the lowest is in Sampang (48.58/100,000 people). The district with the highest incidence of COVID-19 in women is Mojokerto (804.51/100,000 people), while the lowest is in Madiun (51.14/100,000 people). The overall death rate for tuberculosis cases in East Java Province in Indonesia is 3.6%. The highest TB infection CFR was found in Probolinggo (7%), while the lowest was found in Surabaya (0.4%). Meanwhile, the highest CFR of COVID-19 infection was found in Pasuruan (11%), while the lowest was found in Tulungagung 2.1%. Furthermore, the highest cure rate for tuberculosis cases was in Magetan (96.6%), while the lowest was in Batu City (11.3%). Meanwhile, the COVID-19 Case Recovery Rate is defined as a COVID-19 patient with a positive result at the beginning of the RT-PCR, and a negative result at the end of the examination. The highest cure rate for COVID-19 cases was in Sidoarjo (92.6%), while the lowest was found in Tuban (64.5%). The highest success rate of tuberculosis treatment was in Magetan (95.97%), while the lowest was found in Bondowoso (65.89%). Calculation of the number of COVID-19 cases based on age group obtained the highest age in the range of 46-59 years (23,947 individuals), while the lowest was found in the age of 3-6 years (771 individuals). In this study, it was reported that there was no significant relationship between the incidence and mortality of tuberculosis cases (p = 0.912, p>0.05). It was also found that there was no significant relationship between the incidence and case fatality rates for COVID-19 (p = 0.219, p > 0.05), case cure rates and case fatality rates
