Abstract

Dengue Haemorrhagic Fever (DHF) is one of the major public health problems in Indonesia. As the population density increases, the number of sufferers increases. Aedes aegypti mosquitoes are vectors for the disease. The absence of drugs make the best prevention effort by eradicating mosquito nests, killing larvae and adult mosquitoes. Mulberry leaves (Morus alba L.) may be used as larvacides in the presence of chemical compounds of flavonoids and saponins that inhibit feeding and disrupt the process of insect metabolism. The purpose of this research has to determine the effect of mulberry leaf extract (Morus alba L.), to determine the larvicide effect of mulberry leaf extract (Morus alba L.) and to determine the concentration of mulberry leaf extract (Morus alba L.) which is optimal in killing third instar Aedes aegypti larvae. This research used Randomized Design Group (RDG) method with treatment consisted 4 concentrations (0.25%, 0.5%, 0.75%, and 1%), negative control and positive control (ABATE) with 6 repetitions. The results of probit analysis showed that LC50 values were 1.124% and LC90 was 4.413%. From the one way ANOVA test at each concentration of 0.25%, 0.5%, 0.75%, and 1%, the F count result is 208.331, the value was greater than F table which is 2.53 and the significant value is 0.000 (sig <0.05) then mulberry leaf extract (Morus alba L.) has a affected to eliminated of Aedes aegypti larvae. Conclusion from the results of the one way ANOVA test of mulberry leaf extract (Morus alba L.) was affected to eliminated third instar Aedes aegypti larvae

Abstract

The enduring effect of SARS-CoV-2 pandemic has been experienced throughout the past and ongoing three years. Incidences of SARS-CoV-2 co-infected tuberculosis patients were reported globally, including in Italy and several European countries and resulted in a more complicated disease with severe clinical features and poorer clinical outcomes. To effectively manage this co-infection, it is important to be informed of the prevalence and characteristics of an acute SARS-CoV-2 co-infection on TB and determining factors of severity. Therefore, early warning signs can be recognized, monitored closely and managed. This retrospective study, carried out on hospitalized TB patients in Dr. Soetomo Hospital and Universitas Airlangga Hospital, Surabaya, Indonesia, used medical records from March 2020 to December 2022. Samples were from inpatients with a molecularly-Gene Xpert MTB/Rif-confirmed tuberculosis, and currently experienced respiratory and fever symptoms that resembles the symptoms of SARS-CoV-2 infection or exacerbation of tuberculosis. They are then screened and examined using a molecular diagnostic test, with real-time RT-PCR for SARS-CoV-2. A total of 54 (0.7%) patients had TB-SARS-CoV-2 co-infection among 7,786 suspected to have TB, of which 35 had Rifampicin Sensitive (TB-RS), while 19 had TB Rifampicin Resistant (TB-RR) co-infected with SARS-CoV-2. The remaining 2,586 suspected TB patients had only MTB, based on the detection methods of X-pert MTB/RIF, but with negative RT-PCR of SARS-CoV-2. The clinical severity and mortality of TB-SARS-CoV2 co-infected patients were significantly associated with the number of co-morbidities (p=0.0156), and serum haemoglobin levels (p=0.0672), in which p value < 0.05 is considered significant.

Abstract

Globally, the vaccine has been determined as one of the principal policies to tackle the COVID-19 pandemic. However, some vaccinated individuals with two complete doses of inactivated experienced SARS-CoV2 infection, including the healthcare workers (HCWs). This threat led to the emergent need for a vaccine booster with different types of platforms aiming to enhance immunity from the Omicron variant. We conducted a literature study on the concept of heterologous compared to homologous vaccines in COVID-19 vaccination. We obtained 22 studies about COVID-19 booster vaccines. Referring to seven of them, we compared and distinguished between heterologous and homologous vaccines. We then reported the literature review according to PRISMA guideline. The study demonstrated qualitatively that heterologous vaccinations boosted antibody receptor binding domain, neutralizing antibody, and spike-specific Th1 type T cell responses and had an impact on omicron infection when compared to homologous vaccines. In conclusion, heterologous, mRNA based vaccine, predominantly induces cellular and humoral responses better than the homologous vaccine. This increased immune response is expected to provide profound immunity against the Omicron.

Abstract

The rise in dengue fever in recent decades combined with the emergence of COVID-19 at the end of 2019, has created new challenges in the healthcare sector. This research is a descriptive study with a cross-sectional research design and using medical record data at Udayana University Hospital in 2020–2021. According to the study, 1.22% cases of misdiagnosis out of a total of 2365 suspected cases of COVID-19 were found at Udayana University. The majority of cases of misdiagnosis involved people older than 60 years, namely 7 people (24.1%) and were dominated by men, namely 17 people (58.6%). The most common symptoms found are fever, cough, shortness of breath, headache, and malaise, According to laboratory results, dominant patients have thrombocytopenia, followed by high alanine transaminase (ALT), high aspartate transaminase (AST), and leukopenia. The appearance of thrombocytopenia in cases of COVID-19 with dengue fever is the result of suppressed platelet synthesis due to virus induction which causes bone marrow suppression and platelet clearance. Leukopenia and leukocytosis may coexist with lymphopenia as an indicator of disease severity. The similarity of symptoms and laboratory results between COVID-19 and dengue fever allows for misdiagnosis that will affect the patient's management. Therefore, the aim of this study is to determine the misdiagnosis rate of COVID-19 with dengue fever at Udayana University Hospital in 2020–2021, so that it can reduce misdiagnosis of the disease.

Abstract

Indonesia was the third most recent case of leprosy globally in 2020 with 11,173 people, after India and Brazil. Most of the leprosy manifestations are asymptomatic. This is possibly as subclinical leprosy which individuals without leprosy symptoms but have leprosy specific antibodies high levels, so it has the potential to become a transmission and disability. Therefore, an ELISA test need for early detection in preventing leprosy transmission. This study aims to measure IgM and IgG antibody levels in leprosy patients and assess the accuracy of the measurement results. This research is a cross-sectional study. Five patients' blood samples have analyzed for IgM and IgG anti-PGL-1 antibody levels by ELISA. Accuracy interpretation of this measurement based on the %CV. Antibody levels were classified based on the cut-off <605 u/ml as IgM seronegative or <630 u/ml as IgG seronegative, 605–1000 u/ml as low seropositive IgM or 630-1000 u/ml as low seropositive IgG, and >1000 u/ml as high seropositive IgM and IgG. Among five patients examined, 40% had high seropositive leprosy with anti-PGL-1 IgM and IgG antibody titers>1000 u/ml, and 60% of patients had seronegative leprosy. Accuracy in this ELISA test shows high accuracy with %CV <10% in the conversion of OD to antibody titer levels.  IgM and IgG Anti PGL-1 antibody titers by ELISA as one of the parameters in identifying patients at higher risk of leprosy. A significant portion of patients with high seropositive leprosy with high accuracy.

Abstract

A. lumbricoides infection is one from 17 neglected tropical diseases in Indonesia. But, Infection of A. lumbricoides in Indonesia often undiagnosed. This is because stool examination with Kato-Katz's method still rarely done. So it needs something alternative examination that more practical and can be routinely carried out. This study was a diagnostic test for blood eosinofil levels in diagnosing A. lumbricoides infection. This research was conducted at a hospital in Medan. This study involved 63 children who had their parents approval. Children stool were examined by Kato-Katz method as a gold standard and blood eosinofil levels was examined as an index in this study. The results showed sensitivity level of eosinofil is 25% and specificity 96,08%, positive predictive value 60%, negative predictive value 84%, positive likelihood ratio 6,38% and negative likelihood ratio 0,78%. The conclusion is elevated blood eosinofil levels cannot be used as an alternative test Kato-Katz in diagnosing Infection of A. lumbricoides.

Abstract

Leptospirosis is a zoonotic disease caused by bacterial infection, Leptospira interrogans. Indonesia is known for being an endemic country of this disease and Yogyakarta Special Province has become one of the regions with high cases of Leptospirosis. There was lack of information on the L. interrogans prevalence on rats at the public areas, such as school and traditional market. This research was conducted to determine and predict the potential Leptospirosis transmission in public areas, especially in schools, traditional markets,. and the settlement of Yogyakarta. Wild rats were collected from several public places (elementary schools, traditional markets, and Settlement areas) by using single live traps. The rat's blood was centrifuged to obtain the serum. The serum was tested by using immunochromatography of Leptotek Lateral Flow. The collected rats and shrews were euthanized and then identified for the species and the morphological features. Total of 27 rats (67.5%) and shrews 13 (32.5%) were collected. There were six species of collected rats, namely Rattus argentiventer, Rattus norvegicus, Rattus tanezumi, Rattus tiomanicus, and Bandicota bengalensis, while the collected shrew species was Suncus murinus. The rats and shrews from traditional market were negative with L. interrogans, however the positive results was in elementary schools (14.28%), that were from R. norvegicus and S. murinus, moreover the positive infection also showed in the settlements (57.14%), that were from R. argentiventer, R. norvegicus, and R. tiomanicus. These findings indicated that school and settlement must be a concern for the leptospirosis transmission.
