The knowledge mapping of HIV/AIDS in Indonesians living on six major islands using the Indonesian version of the HIV-KQ-18 instrument.

Indonesia's total number of HIV/AIDS cases is still high. Inadequate knowledge about the risk of HIV infection will influence HIV prevention and therapy. This study aimed to map the level of HIV-related knowledge among Indonesians living on six major islands in Indonesia and investigate the relationship between socio-demographic characteristics and HIV/AIDS knowledge. This cross-sectional study used the Bahasa Indonesia version of the HIV Knowledge Questionnaire-18 items (HIV-KQ-18) Instrument. Data collection was done online through the Google form application. A total of 5,364 participants were recruited. The participants from Java had the highest degree of HIV/AIDS knowledge, which was 12.5% higher than participants from Sumatra, Kalimantan, Sulawesi, Papua, and Maluku. Linear regression showed that region, educational level, monthly expenditure, occupation, background in health sciences, and workshop attendance were significantly correlated with HIV knowledge. Participants typically understand that "HIV/AIDS transmission" only happens when sex partners are changed. Additionally, the government still needs improvement in HIV/AIDS education, particularly in the HIV incubation period, HIV transmission from pregnant women to the fetus, and condom use as one method of protection. There are disparities in HIV/AIDS knowledge levels among the major islands of Indonesia. Based on these findings, the government's health promotion program to increase public awareness of HIV/AIDS must be implemented vigorously. Additionally, in line with our research findings, it is essential to broaden the scope of HIV/AIDS education and promotion materials.

Mapping EORTC-QLQ-C30 onto EQ-5D-5L Index in Indonesian Cancer Patients.

OBJECTIVE: This study aims to develop a mapping algorithm for EORTC QLQ-C30 to EQ-5D-5L which can produce utility values in patients with cancer. METHODS: We used a cross sectional study design with 300 cancer patients. The research instruments used were EORTC QLQ-C30 and EQ-5D-5L. Data were collected by interviewing cancer patients who were hospitalized in the Kasuari Installation of Dr Kariadi Hospital Semarang, Indonesia. The Ordinary Least Squares (OLS) regression method was used to predict the utility value of EQ-5D-5L. This study uses two models to predict utility values, namely model 1 with all domains, and model 2 with domains that affect the EQ-5D-5L. The predictive power of regression on the model is evaluated by calculating the mean absolute error (MAE) and root mean square error (RMSE) values. RESULT: The highest score in the functional domain is the 'emotional function' domain (mean: 85.89; SD: 16.04) and the highest symptom domain is 'weakness' (mean: 36.21; SD:21.69). The predicted utility values of models 1 and 2 are 0.683. The mean absolute error (MAE) and root mean square error (RMSE) values of model 1 are 0.128 and 0.173, while in model 2 the MAE and RMSE values obtained are 0.125 and 0.168. CONCLUSION: The development of the mapping algorithm from the EORTC QLQ-C30 to EQ-5D-5L instrument shows a predictive value of utility in a sample of patients with cancer at Dr. Kariadi Hospital, Semarang, Indonesia. The utility prediction in both model is similar, however model 2 involves fewer domains and symptoms.

Cross-cultural adaptation and psychometric properties of the Indonesian version for quality of life among breast cancer patients.

Background: Breast cancer is one of the most important health problems worldwide. Quality of life (QoL) is an important indicator to evaluate symptoms in cancer patients, including those with breast cancer. Culturally suitable, valid, reliable, and appropriate instruments to measure the QoL of breast cancer patients are needed, which is still rare in Indonesia. This study aimed to translate the EORTC QLQ-BR45 instrument into Indonesian and evaluate its psychometrics. Methods: A cross-sectional study was performed on 635 patients conveniently selected from the oncology department in referral hospital. The first phase of this study involved translation of the existing EORTC QLQ-BR45 into Indonesian, and in the second phase, we evaluated its psychometric properties. Construct validity was evaluated using confirmatory factor analysis (CFA). Criterion validity was examined according to the association between disease stage and Karnofsky Performance Scale (KPS). Results: A total of 635 (99.00%) completed the EORTC QLQ-BR45 successfully. The instrument indicated good readability and high content validity. All Cronbach's alpha coefficients were satisfactory (overall value, 0.87). For construct validity, patients with KPS ≥80% did better than those with KPS ≤70% as did two multi-item scales in functional scales (body image and breast satisfaction) and five multi-item scales in symptom scales (systemic therapy side effects, endocrine therapy, and arm, breast, and endocrine sexual symptoms). Body image score of late-stage patients was significantly higher. CFA indicated that the nine-factor structure of the Indonesian EORTC QLQ-BR45 was a good fit for the data. Conclusion: The Indonesian EORTC QLQ-BR45 questionnaire is reliable and valid with good psychometric properties, thus can be used for breast cancer patients in Indonesia.

Determinants of quality of life among people with HIV and tuberculosis in an underserved area in Indonesia: a cross-sectional study.

Introduction: human immunodeficiency virus (HIV) and tuberculosis (TB) remain global health problems and impose a substantial reduction in people´s quality of life (QoL). This study aimed to assess and compare the QoL in HIV and TB patients and factors associated with QoL between those groups. Methods: a cross-sectional study was conducted at a hospital clinic in Jayapura, Indonesia, between December 2022 and March 2023. Those who were aged above 18 years, diagnosed with HIV or TB infection, have been taking HIV or TB medications for at least 3 months, and provided informed consent were eligible to participate. Patients´ QoL was measured using the Bahasa Indonesia version of a validated 26-item World Health Organization Quality of Life - Brief (WHOQOL-BREF) questionnaire. Results: a total of 365 patients with HIV and 125 with TB were included. The majority of participants were Papuan (75.9%) and aged 20 - 65 years (92.9%). More than half of the participants were female (56.5%), employed (50.8%), married (65.5%), and had family support (64.9%). Education level and social support were predictors of poor physical health in the HIV group, while ethnicity was a predictor in the TB group. Patients´ age was associated with poor psychological health in HIV, whereas sex was the associated factor in TB patients. Ethnicity was the only predictor of poor social relationships in those with TB. Whereas patients´ age was a predictor of poor environmental health in the HIV group, marital status, and education were predictors in the TB group. Finally, only social support was associated with poor general QoL in TB patients. Conclusion: tuberculosis (TB) patients had poorer QoL than those with HIV. There is a need for more awareness to support those receiving TB treatment. In addition, further research is needed to understand in more detail the determinants of patients with drug-resistant TB, TB with HIV, and drug-resistant TB-HIV, to ensure that interventions are designed to help them.

Translation and Validation of the Indonesian Version of the Adverse Drug Reaction Severity Level Instruments in Colorectal Cancer Patients.

Introduction: Assessment of the severity of adverse drug reaction (ADR) is very rare in Indonesia. The severity of ADR can describe how serious this affects the clinical condition of the patient. In Indonesia, there are no instruments used to measure the severity of ADR. Purpose: This study aims to translate, pilot test, and validate Hartwig instruments for measuring the severity of ADR in colorectal cancer patients in Indonesia. Patients and Methods: The translation method was used forward-backward technique from English to Indonesian, then being retranslated from Indonesia to English. The instrument of Indonesian version was used to assess the severity of ADR as the effect of chemotherapy. The assessment was conducted to 10 colorectal cancer patients by 30 health workers. The test validity was done based on content validity ratio (CVR) and content validity index (CVI); meanwhile, the test reliability was based on intraclass coefficient correlation (ICC). Results: All of the results of CVR present a value of >0.33, while the range of CVI moves between 0.8 to 1.0, which declares that the instrument is valid. The satisfactory alpha value for reliability is 0.996 with signification of 0.197 (p > 0.05) based on ANOVA analysis. Meanwhile, the ICC value of 0.896 indicates a good reliability among raters. Conclusion: Indonesian version of Hartwig Instrument can be applied in measuring the severity of ADR caused by chemotherapy in colorectal cancer patients.

Geographic Characteristics of Various Cancers in Yogyakarta Province, Indonesia: A Spatial Analysis at the Community Level.

BACKGROUND: Cancer remains a significant public health problem in Indonesia and worldwide. Yogyakarta Province has the largest number of cancer cases in Indonesia. Maps of the distribution of cancer cases are useful tools for stratification of cancer risk and for selective prevention strategies. The aim of this study was to determine the spatial distribution of cancer cases in Yogyakarta Province. METHODS: Cancer patient data registered by the Yogyakarta Provincial Health Office during 2019-2020 were analysed in this study (n=9,933). To evaluate cancer pattern distributions, ArcGIS 10.2 and Excel 2016 software were used. RESULTS: The mean participant age (± standard deviation) was 55.08 ± 15.46 years, and 79.40% were female. Breast and cervical cancer were the most frequently diagnosed, and the majority of patients were located in Sleman district. The incidence of all cancer types varied by county-level. The majority of cancer patients lived below the poverty line. Cancer screening rates were low, and screening was limited to breast and cervical cancer. CONCLUSION: Various types of cancers were identified in Yogyakarta, Indonesia; of them, breast and cervical cancer predominated. Most of the cancer patients were from Sleman district and economically poor areas. Geospatial techniques are useful for identifying environmental factors related to cancer and improving cancer control strategies and resource allocation.

The role of genetic polymorphisms in STIM1 and ORAI1 for erythropoietin resistance in patients with renal failure.

ABSTRACT: Anemia is a common complication in patients with renal failure. While erythropoietin is commonly used to treat anemia, some patients exhibit a poor response to erythropoietin. Since store-operated calcium channel (SOC) signaling is one of the erythropoietin activated pathways, we aimed to investigate the association between the genetic polymorphisms of SOC signaling pathway and erythropoietin resistance in patients with renal failure.Four tagging single nucleotide polymorphisms in STIM1 and five in ORAI1 were selected in this study. Genotyping was performed with the TaqMan Allelic Discrimination assay and the association of individual tagging single nucleotide polymorphisms with erythropoietin resistance was analyzed by multivariable adjusted random intercepts model.194 patients were enrolled in this study. The mean age of participants is 68 years, and 56% were men. The mean erythropoietin resistance index was 9.04 ±â€Š4.51 U/Kg/week/g/dL. We found that patients with the AA genotype of rs1561876 in STIM1, and the CC or CT genotypes of rs6486795 in ORAI1, were associated with increased risk of erythropoietin resistance. Functional annotation of expression quantitative trait loci revealed that the AA genotype of rs1561876 in STIM1 has a relatively lower expression of ribonucleotide reductase catalytic subunit M1 in skeletal muscle, while the CC genotype of rs6486795 in ORAI1 has a relatively higher expression of ORAI1 in the whole blood and thyroid.Overall, we demonstrate a significant association between erythropoietin resistance and genetic polymorphisms of STIM1 and ORAI1. Annotation prediction revealed the importance of SOC-mediated calcium signaling for erythropoietin resistance.

Pharmacogenetics of antiemetics for chemotherapy-induced nausea and vomiting: A systematic review and meta-analysis.

A substantial proportion of cancer patients experience chemotherapy-induced nausea and vomiting (CINV) despite the use of antiemetic drugs. Prevalent genetic polymorphisms involved in antiemetic drug metabolism, drug transport and receptor pathways likely affect the effectiveness of antiemetics. Knowledge on which polymorphisms to integrate into individualised clinical care is needed. We did a systematic review evaluating the association between polymorphisms and effectiveness of antiemetics in cancer patients receiving moderately to highly emetogenic chemotherapy. Twenty studies n = 2331 evaluated eight polymorphisms in five candidate genes involved in 5-HT3 antagonist pathways. HTR3C C1214G increased the risk of acute chemotherapy-induced vomiting in the dominant model (odds ratio (OR) = 2.67, 95 % confidence interval (CI): 1.08-6.63). ABCB1 C3435T reduced the risk of acute CINV in the recessive model (OR = 0.60, 95 % CI: 0.44-0.81). Future studies should evaluate candidate genes that affect pharmacogenetics of other antiemetics beside 5-HT3 antagonists.

Cervical cancer prevention in Indonesia: An updated clinical impact, cost-effectiveness and budget impact analysis.

INTRODUCTION: The clinical and economic impact of cervical cancer consistently become a serious burden for all countries, including Indonesia. The implementation of HPV vaccination policy for a big country such as Indonesia requires a strong commitment from several decision-makers. The aim of this study was to provide a comprehensive description on cost-effectiveness and the budget-impact of HPV vaccination policy in Indonesia. METHOD: A cohort Markov model was used to evaluate the cost and the clinical impact of HPV vaccination for 10 years old girls in Indonesia. The researchers consider two doses of all three available HPV vaccines adjusted with the HPV infection profilewith 95% vaccination coverage to estimate the national cervical cancer incidence and mortality. The Budget impact analysis explores three different scenarios covering (1) Two districts per year expansion, (2) oneprovince per year expansion and (3) achieving the National Immunization Program in 2024. RESULTS: Upon fully vaccinating almost 2.3 million 10-year-old girls, 34,723; 43,414; and 51,522 cervical cancer cases were prevented by Quadrivalent, Bivalent and Nonavalent vaccines, consecutively. Furthermore, the highest (591 cases) and lowest (399 cases) mortality were prevented by Nonavalent and Quadrivalent vaccines, respectively. Most of the vaccines were considerably cost-effective and only the Bivalent vaccine with the GAVI/UNICEF price which will be considered a cost-saving strategy.To provide national coverage of HPV vaccination in Indonesia, the government has to provide an annual budget of about US$49 million and US$22 million using the government contract price and GAVI/UNICEF price, respectively. CONCLUSION: HPV vaccination shows a cost-effective strategy and the budget required to provide this policy is considerably affordable for Indonesia.

Impact of organophosphate exposure on farmers' health in Kulon Progo, Yogyakarta: Perspectives of physical, emotional and social health.

OBJECTIVE: The exposure of organophosphate could be caused by the absorption in some parts of the body like skin and breath. Toxicity may cause nausea, vomiting and dizziness which are not too specific related with the pesticide toxicity. The purpose of this study is to understand the association between organophosphate exposure and farmers' health in Kulon Progo County from the perspectives of physical, emotional and social health. METHODS: This study was conducted using descriptive observational design. The blood sample was collected during harvesting periods in 2016. The inclusion criterion of farmers was using organophosphate-contained pesticide during the planting period of red onion. The farmers who had renal disease, liver disease and cancer were excluded. The organophosphate exposure parameters were the duration and frequency of pesticide application, width of the area, serum cholinesterase activity and the completeness of personal protective equipment. RESULTS: Among 84 farmers, most of them were male (85.7%), and the mean age was 49.1 (standard deviation: 12.5) years; 71.4% of the subjects experienced tremor, 17.86% experienced dizziness and 8.33% subjects experienced nausea-vomiting after pesticide application. According to the pesticide application, in average, subjects used pesticide 1.4 h/day with the area of 1.285 m2. The frequency of pesticide used is three times per week. Around 97.6% subjects used incomplete personal protective equipment. The average of serum cholinesterase activity in subjects with tremor is higher than subjects without tremor (p > 0.05). There is a significant association between serum cholinesterase activity and creatinine content (p < 0.05). The farmers' quality-of-life domain scores are lower than the scores of the normal population in Yogyakarta. CONCLUSION: Organophosphate exposure may affect the farmers' physical health and quality of life.

Impact of chemotherapy-induced nausea and vomiting on quality of life in indonesian patients with gynecologic cancer.

BACKGROUND: Quality of life (QoL) has become a major outcome in the treatment of patients with cancer. This study is aimed at examining the impact of chemotherapy-induced nausea and vomiting on QoL of patients with gynecologic cancer in Indonesia. METHODS: Chemotherapy-naive patients with gynecologic cancer, who were treated with cisplatin at a dosage 50 mg/m or higher as monotherapy or as part of combination chemotherapy regimens, were recruited in the Oncology Department, Dr. Sardjito Hospital, Yogyakarta, Indonesia. Quality of life was assessed by using the Indonesian version of the European Organization for Research and Treatment for Cancer of Quality of Life Questionnaire and Short Form-36, administered immediately before and on day 5 after chemotherapy administration. Patients used a daily diary to record nausea and vomiting during 5 days after chemotherapy. RESULTS: Most (74.9%) of the 179 patients experienced delayed emesis during the 5 days after chemotherapy despite prophylactic use of antiemetics. The delayed nausea and emesis caused significant negative impact on patients' QoL. Nausea in the delayed phase caused negative effects on patients' QoL. CONCLUSIONS: Patients reported a negative impact on the QoL of delayed emesis after chemotherapy. Poor prophylaxis of patients' nausea and vomiting after chemotherapy interferes with patients' QoL. Medical and behavioral interventions may help to alleviate the negative consequences of chemotherapeutic treatment in patients with gynecologic cancers treated with suboptimal antiemetics.

Translation and validation of EORTC QLQ-C30 into Indonesian version for cancer patients in Indonesia.

OBJECTIVE: Quality of life studies in Indonesia are still uncommon. This research was aimed to validate the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 in Indonesian version. The standard procedure of forward-backward translation was adhered to in the translation procedures. The validity procedure included reliability, convergent and discriminant validity, known-groups validity, factor analysis and external convergent validity. METHODS: Data were collected from cancer patients in the Oncology Department of Sardjito Hospital, Yogyakarta, Indonesia, who were treated with cisplatin at the dosage ≥50 mg/m(2) as monotherapy or in combinations. The Short Form-36 was used to assess the external convergent validity of our translated questionnaire. RESULTS: One hundred and twenty-eight patients were recruited from March 2009 to November 2009. The internal consistency with values of >0.70 was observed in the Indonesian version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 scales. All items in the questionnaire met the criteria of convergent and discriminant validity, except for items 5. Both of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 and the Short Form-36 showed that different diagnoses were associated with a similar impact on quality of life. Factor analysis showed that only the role function and social function loaded onto the second factor together. Correlations between the Indonesian versions of both questionnaires were moderate: between 0.18 and 0.48 for the physical, emotional, social, fatigue and pain domains. CONCLUSIONS: The Indonesian version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 can be used as a questionnaire to assess quality of life in Indonesian cancer patients with high-emetogenic treatments.
