Abstract
By the end of 2022, the nationwide incidence of stunting remained high, including in Lampung Province, where it was 15.8%, above the target of 14% to be achieved by 2024. Since 2019, stunting has become a national priority due to suspected factors such as low nutrition intake, especially from animal protein sources, high rates of worm infections, and low compliance of under-fives in consuming deworming drugs. Therefore, this research aimed to analyze the relationship between deworming consumption, adequacy of animal protein intake, and stunting incidence in children aged 12-59 months in Bandar Lampung in 2022. This research used an analytic survey with a cross-sectional approach to analyze the relationship between deworming consumption, adequacy of animal protein intake, and stunting in under-fives at two priority stunting handling neighbourhoods in Bandar Lampung, namely Way Gubak and Karang Maritim. The sample consisted of 262 under fives and their mothers who visited the integrated health post in the selected neighbourhoods from November to December 2022, and the data obtained were analyzed using logistic regression. The results revealed a relationship between the consumption of an deworming and varying animal protein consumption with stunting incidence. This indicated a need to promote the importance of consuming deworming and adequate consumption of animal protein with variation to prevent stunting in children in Bandar Lampung.

Abstract
Abstract
Background
Dengue infection is one of the most common viral infections globally, with a broad spectrum of clinical manifestations, including hemorrhage and shock. Early diagnostic confirmation of dengue infection is essential, but some areas may not have the appropriate diagnostic tools while its clinical symptoms are similar to other diseases. We aim to determine some significant clinical characteristics and laboratory parameters in differentiating dengue from other causes of febrile.
Results
This study included 527 dengue patients and 268 control patients. Multivariate analysis showed older age (OR = 12.11; 95% 5.42–26.63, p < 0.001), the absence of diarrhea (OR = 0.12; 95% CI 0.06–0.25, p < 0.001), leukopenia (OR = 13.35; 95% CI 4.99–38.71, p < 0.001), thrombocytopenia (OR = 7.12; 95% CI 2.37–21.38, p < 0.001), and normal ESR (OR = 3.03; 95% CI 1.54–5.96, p = 0.001) are significant parameters in differentiating dengue with excellence (AUC value of 0.96) and good fit of the model (p value = 0.8). The cut-off is two significant variables with a sensitivity of 91.4% and specificity of 87.5%.
Conclusions
Two or more clinical signs can help clinicians differentiate dengue from other acute febrile illnesses.

Epidemiology of soil-transmitted helminth infections in Semarang, Central Java, Indonesia. PLoS Negl Trop Dis 2020; 14:e0008907. [PMID: 33370267 PMCID: PMC7793285 DOI: 10.1371/journal.pntd.0008907] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2020] [Revised: 01/08/2021] [Accepted: 10/21/2020] [Indexed: 11/18/2022] Open
Abstract
Soil-transmitted helminth (STH) infections are endemic in Indonesia. However, prevalence data for many parts of the country are incomplete. The aim of this study was to determine human STH prevalence and knowledge and practices relating to STH risk behaviour, to provide a current view of the status of STH infection in rural communities in Central Java. A cross-sectional survey of 16 villages was conducted in Semarang, Central Java in 2015. Demographic and household data together with information about knowledge and practices relating to STH and hygiene were elicited through face-to-face interviews. Stool samples were collected and examined using the flotation method. Children (aged 2–12 years) also had their haemoglobin (Hb) levels, height and weight data collected, and BMI estimated. Data were analysed using univariate logistic regression analysis. A total of 6,466 individuals with a mean age of 33.5 years (range: 2–93) from 2,195 households were interviewed. The overall prevalence of STH was 33.8% with Ascaris lumbricoides (roundworm) the predominant nematode identified (prevalence = 26.0%). Hookworm and Trichuris trichiura (whipworm) were found in 7.9% and 1.8% of participants, respectively. Females were at increased odds of infection with A. lumbricoides (adjusted OR 1.14, 95% CI [1.02–1.29], p = 0.02). Adults in age groups 51–60 and over 60 years had the highest odds of being infected with hookworm (adjusted OR 3.01, 95% CI [1.84–4.91], p<0.001 and adjusted OR 3.79, 95% CI [2.30–6.26], p<0.001, respectively) compared to 6–12 year olds. Farmers also had higher odds of being infected with hookworm (adjusted OR 2.36, 95% CI [1.17–4.76], p = 0.02) compared to other occupation categories. Poverty (OR 2.14, 95% CI [1.77–2.58], p<0.001), overcrowding (OR 1.35, 95% CI [1.27–1.44], p<0.001), goat ownership (OR 1.61, 95% CI [1.10–2.41], p = 0.02) and the presence of dry floor space in the home (OR 0.73, 95% CI [0.58–0.91], p = 0.01) were all household factors significantly associated with an increased odds of infection. Infection with STH was not significantly associated with the gastrointestinal illness (p>0.05), BMI or Hb levels; however, one third of all 2–12 year olds surveyed were found to be anaemic (i.e. Hb concentrations below 110g/l or 115g/l for children under 5 and 5 years or older, respectively), with a greater proportion of school-age children at risk. Knowledge and behaviour related to hygiene and gastrointestinal diseases varied widely and were generally not associated with STH infection. The study revealed that STH infection remains endemic in Central Java despite ongoing deworming programs. Current control efforts would benefit from being re-evaluated to determine a more effective way forward. Among the major NTDs, STH are one of the most common disabling chronic infections. Currently available drug treatments, whilst considered safe and generally well tolerated, do not confer protection against new infections. In Indonesia, prevalences of STH of up to 90% have been reported but these estimates are based on data from the 1980s and 90s. More up-to-date STH prevalence estimates are urgently needed to help guide future control efforts. A cross-sectional survey was conducted in rural villages in Semarang, Central Java to determine human STH prevalence and associated risk factors. One-third of all cohort participants were positive for STH with prevalences of 26%, 7.9% and 1.8% identified for Ascaris lumbricoides, hookworm and Trichuris trichiura at 7.9% and 1.8%, respectively. Risk of A. lumbricoides infection was higher for females, whilst farmers and adults over 50 had an increased risk of hookworm infection. Poverty, overcrowding in the home and goat ownership were also associated with an increased risk at the household level. Soil-transmitted helminthiases remains a significant health problem in Central Java, Indonesia, exacerbated by limited knowledge about STH, poor sanitation and hygiene and poverty prevalent in the region. Control efforts would benefit from an integrated approach emphasising WASH, health education and chemotherapy. Further studies investigating environmental contamination with STH in and around homes in endemic areas could provide further insight into links between household factors and STH identified in our study.

Abstract
The practice of community pharmacy in low and middle-income countries, including in Indonesia, is often described as in the state of infancy with several intractable barriers that have been substantially and continuously hampering the practice. Such description might be valid in highlighting how pharmacy is practiced and the conditions within and beyond community pharmacy organizations. Therefore, it is not surprising that the concept of integrating community pharmacy into the primary care system may not be considered in the contemporary discourse despite the fact that community pharmacy has been operating within communities for years. However, in the case of Indonesia, we argue that changes in the health care system within the past decade particularly with the introduction of the universal health coverage (UHC) in 2014, may have significantly amplified the role of pharmacists. There is good evidence which highlights the contribution of pharmacist as a substantial health care element in primary care practice. The initiative for employing pharmacist, identified in this article as primary care pharmacist, in the setting of community health center [puskesmas] and the introduction of affiliated or contracted community pharmacy under the UHC have enabled pharmacist to work together with other primary care providers. Moreover, government agenda under the “Smart Use of Medicines” program [Gema Cermat] recognizes pharmacists as the agent of change for improving the rational use of medicines in the community. Community pharmacy is developing, albeit slowly, and is able to grasp a novel position to deliver pharmacy-related primary care services to the general public through new services, for example drug monitoring and home care. Nevertheless, integrating community pharmacy into primary care is relatively a new notion in the Indonesian setting, and is a challenging process given the presence of barriers in the macro, meso- and micro-level of practice.

Abstract
Background and Aim: Lymphatic filariasis (LF) is a lesser-known parasitic disease, which contributes to significant decreases in overall health. This study investigated the presence of Brugia malayi in mosquitoes collected in the South Borneo Province, Indonesia. Materials and Methods: Mosquitoes were collected through bare leg collection methods after sunset in several areas of the Hukai and Gulinggang villages in the Balangan District. The collected mosquitoes were identified based on morphological features and dissected to find microfilaria and then pooled through species for polymerase chain reaction (PCR) microfilaria detection. Results: A total of 837 female mosquitoes consisting of at least 14 species were selected; they were dissected, and no microfilariae were found. Mosquitoes were divided into 69 pools for PCR analysis. PCR revealed that 8.7% (6/69) of the pools were positive for B. malayi, including Mansonia annulifera (4 pools), Aedes albopictus (1 pool), and Culex tritaeniorhynchus (1 pool). Conclusions: These results suggested that mosquito dissection was not an optimum method for finding microfilaria. M. annulifera, C. tritaeniorhynchus, and A. albopictus mosquitoes might play an important role in the transmission of LF in the Balangan District. Information from this study could be used for the prevention of transmission or vector control programs in Indonesia.

Abstract
We compared the impact of annual and semiannual mass drug administration (MDA) on the prevalence of Brugia timori and Wuchereria bancrofti in Flores Island. Two villages (Paga, B. timori only; Lewomada, co-endemic) received annual MDA with diethylcarbamazine/albendazole and a larger village (Pruda, co-endemic) received semiannual MDA. Infection parameters (microfilariae [Mf], antibodies to recombinant filarial antigen BmR1 [Brugia Rapid (BR)], and a test for W. bancrofti antigenemia [immunochromatographic test (ICT)]) were assessed before and after treatment. The crude Mf prevalence in Pruda decreased after five semiannual treatments from 14.2% to 1.2%, whereas the Mf prevalence in the other two villages decreased after three annual treatments from 3.9% to 0% and from 5% to 0.3%, respectively. ICT positivity prevalence in Pruda and Lewomada decreased from 22.9% and 6.5% to 7% and 0.8%, respectively, whereas BR antibody prevalence in Pruda, Lewomada, and Paga decreased from 28.9%, 31.7%, and 12.5% to 3.6%, 4.1%, and 1.8%, respectively. Logistic regression analysis indicated that that Mf, BR, and ICT prevalence decreased significantly over time and that for the Mf and ICT outcomes the semiannual treatment had higher odds of positivity. Model-adjusted prevalence estimates revealed that apparent differences in treatment effectiveness were driven by differences in baseline prevalence and that adjusted prevalence declined more rapidly in the semiannual treatment group. We conclude that in this setting, annual MDA was sufficient to reduce Mf prevalence to less than 1% in areas with low to moderate baseline prevalence. Semiannual MDA was useful for rapidly reducing Mf prevalence in an area with higher baseline endemicity.

Abstract
Soil transmitted helminthiasis are common in the world and cause illness, especially in developing countries. It can cause infection in humans by contact with parasitic eggs or larvae that live in moist and warm soil. Soil-transmitted helminthiasis is often caused by Ascaris lumbricoides, Trichuris trichiura, Ancylostoma duodenale, and Necator americanus. In Indonesia, Soil transmitted helminthiasis prevalence is still high in some places. The tropical climate and high humidity support for the development of worms like in Sorong District, but there was no data. The purpose of this study is to identify the presece of Soil transmitted helminthiasis in primary school children in Sorong District. A cross-sectional study was conducted in two elementary schools located in Sorong District, West Papua, Indonesia. The two elementary schools are SDN 22 in Klain village and SD Inpres 24 in sub-district Mayamuk. Once collected, the pot that has contained stool is given formalin 10%. Stool examinattion using direct smear method to determine the presence of soil transmitted helminthiasis. Researchers get the subject as many as 147 children. The proportion of elementary school children by sex consists of 72 boys (49%) and 75 girls (51%). The prevalence of Soil transmitted helminthiasis as a whole was 30.6% (45/147) with 40.1% (18/45) single infections and 59.9% (27/45) mixed infections. The single infection that most frequent is Trichuris trichiura, then followed by Ascaris lumbricoides. Soil-transmitted helminthiasis mostly found in girl than boy and mostly found in 6-9 years age group. The worm species that infect elementary school children in the district is Ascaris lumbricoides, Trichuris trichiura, Hookworm, and Strongyloides stercoralis. This is probably related with the climate and low sanitation level. To eliminate soil transmitted helminthiasis among elementary school children, in addition to routine treatment also needs intensive counseling about the importance of maintaining personal hygiene and the environment.

Abstract
'Rama and the Worm' is a shadow puppet production targeting neglected diseases in Central Java. It is an entertainment-based intervention study to promote health by reducing the impact of parasitic diseases such as soil-transmitted helminths (STH). The study uses traditional Javanese shadow puppetry (wayang kulit) as a vehicle in village communities to disseminate health messages and promote behaviour change to prevent diseases caused, primarily, by inadequate sanitation and poor hygiene. The health education messages contained in the play, although using traditional characters and themes, required the creation of a completely new narrative script, using characters and plot lines familiar to the wayang kulit repertoire, but placing them in new situations that relate specifically to health promotion objectives. The intervention was piloted in a village in Central Java, Indonesia using a pre/post design with both qualitative and quantitative analysis. A total of 96 male and female villagers, aged between 7 and 87 years, provided both baseline and follow up data. Participant knowledge and behaviours related to gastrointestinal and helminth-related disease were assessed before and after the intervention through a questionnaire administered by interview. Results revealed statistically significant improvements in both knowledge (48.6% pre-intervention score vs. 62.8% post-intervention score, p < 0.001) and behaviour (77.4% vs. 80.6%, p = 0.004) related to gastrointestinal and helminth disease. Findings of the study indicate the wayang kulit performance is an effective health education tool. The results provide proof of concept with scaling up the next step forward. The wayang kulit production provides a significant additional component for an integrated, comprehensive approach to reduction and elimination of STH infection.

The Importance of Socio-Economic Versus Environmental Risk Factors for Reported Dengue Cases in Java, Indonesia. PLoS Negl Trop Dis 2016; 10:e0004964.

Abstract
BACKGROUND Dengue is a major mosquito-borne viral disease and an important public health problem. Identifying which factors are important determinants in the risk of dengue infection is critical in supporting and guiding preventive measures. In South-East Asia, half of all reported fatal infections are recorded in Indonesia, yet little is known about the epidemiology of dengue in this country. METHODOLOGY/PRINCIPAL FINDINGS Hospital-reported dengue cases in Banyumas regency, Central Java were examined to build Bayesian spatial and spatio-temporal models assessing the influence of climatic, demographic and socio-economic factors on the risk of dengue infection. A socio-economic factor linking employment type and economic status was the most influential on the risk of dengue infection in the Regency. Other factors such as access to healthcare facilities and night-time temperature were also found to be associated with higher risk of reported dengue infection but had limited explanatory power. CONCLUSIONS/SIGNIFICANCE Our data suggest that dengue infections are triggered by indoor transmission events linked to socio-economic factors (employment type, economic status). Preventive measures in this area should therefore target also specific environments such as schools and work areas to attempt and reduce dengue burden in this community. Although our analysis did not account for factors such as variations in immunity which need further investigation, this study can advise preventive measures in areas with similar patterns of reported dengue cases and environment.

Dengue in Java, Indonesia: Relevance of Mosquito Indices as Risk Predictors. PLoS Negl Trop Dis 2016; 10:e0004500. [PMID: 26967524 PMCID: PMC4788303 DOI: 10.1371/journal.pntd.0004500] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2015] [Accepted: 02/09/2016] [Indexed: 11/19/2022] Open
Abstract
Background No vaccine is currently available for dengue virus (DENV), therefore control programmes usually focus on managing mosquito vector populations. Entomological surveys provide the most common means of characterising vector populations and predicting the risk of local dengue virus transmission. Despite Indonesia being a country strongly affected by DENV, only limited information is available on the local factors affecting DENV transmission and the suitability of available survey methods for assessing risk. Methodology/principal findings We conducted entomological surveys in the Banyumas Regency (Central Java) where dengue cases occur on an annual basis. Four villages were sampled during the dry and rainy seasons: two villages where dengue was endemic, one where dengue cases occurred sporadically and one which was dengue-free. In addition to data for conventional larvae indices, we collected data on pupae indices, and collected adult mosquitoes for species identification in order to determine mosquito species composition and population density. Traditionally used larval indices (House indices, Container indices and Breteau indices) were found to be inadequate as indicators for DENV transmission risk. In contrast, species composition of adult mosquitoes revealed that competent vector species were dominant in dengue endemic and sporadic villages. Conclusions/significance Our data suggested that the utility of traditional larvae indices, which continue to be used in many dengue endemic countries, should be re-evaluated locally. The results highlight the need for validation of risk indicators and control strategies across DENV affected areas here and perhaps elsewhere in SE Asia. Geographically and economically, Indonesia is one of the most prominent countries in SE Asia, yet many of its endemic infectious diseases are poorly managed, controlled and understood. This includes dengue virus (DENV), which can result in serious human disease and is transmitted by mosquitoes. Dengue risk assessment is a key factor in managing the impact of infection on public health, and this often relies on assessing the presence and nature of mosquitoes through a number of indices associated with the occurrence of larvae and the location/availability of breeding containers. Here we assessed traditionally used indices in combination with other indicators including pupae indices, and the presence of adult mosquitoes in areas with different dengue status: endemic, sporadic or free. Our data suggested that traditional indices were poor indicators of reported local DENV transmission. This has important consequences for design and focus of risk management strategies and efforts to control DENV locally as well as elsewhere in the region.

Neglected tropical diseases among the Association of Southeast Asian Nations (ASEAN): overview and update. PLoS Negl Trop Dis 2015; 9:e0003575. [PMID: 25880767 PMCID: PMC4400050 DOI: 10.1371/journal.pntd.0003575] [Citation(s) in RCA: 81] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/23/2022] Open
Abstract
The ten member states of the Association of Southeast Asian Nations (ASEAN) constitute an economic powerhouse, yet these countries also harbor a mostly hidden burden of poverty and neglected tropical diseases (NTDs). Almost 200 million people live in extreme poverty in ASEAN countries, mostly in the low or lower middle-income countries of Indonesia, the Philippines, Myanmar, Viet Nam, and Cambodia, and many of them are affected by at least one NTD. However, NTDs are prevalent even among upper middle-income ASEAN countries such as Malaysia and Thailand, especially among the indigenous populations. The three major intestinal helminth infections are the most common NTDs; each helminthiasis is associated with approximately 100 million infections in the region. In addition, more than 10 million people suffer from either liver or intestinal fluke infections, as well as schistosomiasis and lymphatic filariasis (LF). Intestinal protozoan infections are widespread, while leishmaniasis has emerged in Thailand, and zoonotic malaria (Plasmodium knowlesi infection) causes severe morbidity in Malaysia. Melioidosis has emerged as an important bacterial NTD, as have selected rickettsial infections, and leptospirosis. Leprosy, yaws, and trachoma are still endemic in focal areas. Almost 70 million cases of dengue fever occur annually in ASEAN countries, such that this arboviral infection is now one of the most common and economically important NTDs in the region. A number of other arboviral and zoonotic viral infections have also emerged, including Japanese encephalitis; tick-borne viral infections; Nipah virus, a zoonosis present in fruit bats; and enterovirus 71 infection. There are urgent needs to expand surveillance activities in ASEAN countries, as well as to ensure mass drug administration is provided to populations at risk for intestinal helminth and fluke infections, LF, trachoma, and yaws. An ASEAN Network for Drugs, Diagnostics, Vaccines, and Traditional Medicines Innovation provides a policy framework for the development of new control and elimination tools. Together with prominent research institutions and universities, the World Health Organization (WHO), and its regional offices, these organizations could implement important public health improvements through NTD control and elimination in the coming decade.
