RESUMO
OBJECTIVE: The patients with advanced-stage ovarian cancer have higher factors complicating surgery; thus, the best choice for them is surgery with chemotherapy with six cycles of adjuvant chemotherapy. Generally, chemotherapy can be evaluated in various ways, phsychal examination, radiology examination, and laboratory examination. This study aims is to examine if the measurement of the platelet/lymphocyte ratio (PLR) and neutrophil/lymphocyte ratio (NLR) can be used to predict a patient's response to chemotherapy. METHODS: Analytic observational study with a case-control design conducted in the Dr. Hasan Sadikin Hospital in Bandung from 2017 to 2018. This study used the medical record of ovarian cancer patients with post-surgery complete blood counts and histopathological reports. The sample size was determined based on the categorical test's statistical calculation to obtain a total number of at minimal 90 samples. All the study subjects who had undergone complete chemotherapy were followed up for 6 months. Their response to chemotherapy was assessed with a clinical examination, ultrasonography, and a CA-125 blood test every 3 months. RESULTS: In 2017-2018, 504 patients were diagnosed with ovarian cancer at the Dr. Hasan Sadikin Hospital in Bandung, Indonesia. After reassessment, 116 patients had stage I to III ovarian cancer and underwent cytoreduction followed by platinum chemotherapy. The age, cancer stage, and types of epithelial cells in the platinum-sensitive and platinum-resistant patients were characterized. There were significant differences between the two groups in age and cancer stage characteristics (p < 0.05). The increase in platelet/lymphocyte (p = 0.003) and neutrophil/lymphocyte ratios (p = 0.026) are associated with the increase in the response to platinum chemotherapy against epithelium-based cancers. CONCLUSION: A patient's NLR and PLR are strongly associated with his response to chemotherapy.

OBJECTIVE: One of the important treatments for cervical cancer is radiation therapy. This study sought to determine the role of curcumin as a radio-sensitizing agent for use with radiation therapy for cervical cancer. To accomplish this, we assessed the levels of survivin, which is an anti-apoptotic protein that plays a role in cell division and apoptosis inhibition. METHOD: This study used a quasi-experimental design, including a pretest-posttest control group design approach. The study subjects included cervical carcinoma stage IIB-IIIB patients who were scheduled to undergo surgery at the Hasan Sadikin Hospital Bandung during the research period. The advanced cervical cancer patients were assigned to two groups: i) those who received curcumin + radiation therapy and ii) those who received placebo + radiation therapy. RESULTS: In the group treated with curcumin + radiation, 15 (75%) patients showed decreased survivin levels and 5 (25%) showed increased survivin levels. Whereas, in the placebo + radiation group, there were 8 (40%) patients who showed decreased survivin levels and 12 (60%) who showed increased survivin levels. CONCLUSION: In conclusion, curcumin is an effective, alternative radiosensitizer agent for application in cervical cancer treatment.

BACKGROUND: Human papillomavirus (HPV)-45 genotype circulates in high percentage in Bandung area - Indonesia, after HPV-16 and HPV-18. The aim of this study was to analyse variations of major capsid (L1) HPV-45 and its phylogeny. Furthermore in silico protein structure and epitope prediction was explored. METHODS: L1 gene of HPV-45 was amplified, sequenced and aligned. Phylogenetic tree had been built and compared with a complete L1 HPV-45 sequence. Structure and epitope prediction of L1 protein were then developed in silico. RESULTS: Of 5 L1 HPV-45 sequences collected, we have detected one variant of sub lineage A2 which was considered as a new variant, and two variants of B2. Superimposition of structure of these two variants with reference showed very similar structure. Furthermore, seven amino acid substitutions were found within these L1 variants of which two substitutions might change the polarity of corresponding amino acid I329T and S383G. The S383G occurred in surface loop (HI-Loop) of new L1 HPV-45 variant. CONCLUSION: Similar structure of Indonesian variants indicates that amino acids variations do not affect the L1 structure. However, one substitution with altered amino acid polarity found within the area of surface loop suggests a potential impact in antibody recognition and neutralization.

Low hemoglobin (Hb) or anemia is common among pregnant women in developing countries which may cause adverse pregnancy outcomes and maternal deaths. Our study aimed to assess Hb level measured by midwives in primary health care facility at rural area of Jatinangor, Indonesia, and to explore whether the anemia was due to iron deficiency (IDA) or ß-thalassemia trait (ß-TT). Pregnant women (n = 105) had finger prick test for Hb level during a regular antenatal care examination from October to November 2016. Hb level by finger prick test was compared with venous blood, measured by complete blood count (CBC). Indices including MCV and MCH and indices of Shine & Lal, Mentzer, Srivastava, Engels & Frase, Ehsani, and Sirdah were analyzed to differentiate anemia due to IDA and anemia due to suspect ß-TT. HbA2 was measured to confirm ß-TT. Anemic pregnant women were found in 86.7% by finger prick test compared to 21.9% (n = 23) by CBC. The prevalence of ß-TT in our study was 5.7%. Hb measurement among pregnant women in low resource area is highly important; however, finger prick test in this study showed a high frequency of anemia which may lead to iron oversupplementation. A standard CBC is encouraged; MCV and MCH would help midwives to identify ß-TT.
RESUMO
BACKGROUND: As in other developing countries, cervical cancer is the most frequent gynecologic malignancy in Indonesia. Persistent high risk genotypes of human papillomavirus (HPV) that infect the cervical tissue have been established as the etiology of cervical cancer. This study aimed to explore the profile of cervical cancer patients and the infected HPV genotypes at Dr. Hasan Sadikin General Hospital-Bandung. MATERIALS AND METHODS: During the year 2010, 554 cervical cancer patients were registered. In a subset of the patients during July-November 2010, 40 randomized fresh biopsies were tested for HPV genotype after obtained informed consent. The distribution of HPV genotypes and the association to risk factors were analysed. RESULTS: The result showed that 62.5% of the tested biopsies were infected by multiple HPV infections, with HPV-16 found in most of the cervical cancer patients (90%). Marriage at age younger than 16 years old was statistically significant in relation to multiple HPV infection (p=0.003), but not parity more than three times (p=0.59). CONCLUSIONS: Although high paritiy in our study was not associated with multiple HPV infection, good family planning programs and reproductive health education need to be emphasized in Indonesia as high parity and marriage at young age might increase the chance of cervical cancer development.

BACKGROUND: Persistent infection with high risk human papillomavirus (hrHPV) is strongly associated with cervical cancer. Normal cervical cells may also harbor hrHPV, and detection of early hrHPV infection may minimize risk of cervical cancer development. This study aimed to compare two commercial HPV genotyping assays that may affordable for early screening in a limited-resource setting in Bandung, Indonesia. MATERIALS AND METHODS: DNA from cervical biopsies with histologically confirmed as squamous cell cervical cacinoma were HPV genotyped by Linear Assay 1 (Roche Diagnostics, Mannheim, Germany) or Linear Assay 2 (Digene HPV Genotyping RH Test, Qiagen Gaithersburg, MD). In a subset of samples of each group, HPV genotype results were then compared. RESULTS: Of 28 samples genotyped by linear assay 1, 22 (78.6%) demonstrated multiple infections with HPV-16 and other hrHPV types 18, 45 and/or 52. In another set of 38 samples genotyped by linear assay 2, 28 (68.4%) were mostly single infections by hrHPV type 16 or 18. Interestingly, 4 samples that had been tested by both kits showed discordant results. CONCLUSIONS: In a limited-resource area such as in Indonesia, country with a high prevalence of HPV infection a reliable cervical screening test in general population for early hrHPV detection is needed. Geographical variation in HPV genotyping result might have impacts for HPV prevalence and molecular epidemiology as the distribution in HPV genotypes should give clear information to assess the impact of HPV prophylactic vaccines.

AIM: to estimate the occupational risk of HBV, HCV and HIV infections among Indonesian HCWs. METHODS: the model developed by WHO was used to calculate the risk. The input parameters were selected from the best available evidence in Indonesia through a literature review. RESULTS: in 2005, sharps injuries led to an estimated 1445 infections with HBV, 399 with HCV and 18 with HIV among health-care workers (HCWs) in Indonesia. The attributable fractions of these infections due to sharps injuries among HCWs in Indonesia were estimated to be approximately 44%, 47%, and 11% for HBV, HCV and HIV, respectively. CONCLUSION: those data show that HCWs in Indonesia may face significant occupational risks of contracting viral hepatitis due to sharps injuries. In order to produce better estimates prospective studies in different health care settings are urgently needed.

Indonesia is facing a growing HIV-epidemic that in many areas is driven by injecting drug use (IDU). IDUs underutilize health services, partly because of legal aspects which also cause that many are held in prison, where further HIV- transmission may take place. Most HIV-infected patients present with advanced HIV-AIDS and many deaths before starting antiretroviral treatment. The growing HIV-epidemic in Indonesia has socio-economical implications for individual patients as well as for the health system and for society. IMPACT, a multidisciplinary university-based program in Bandung, West-Java, integrates HIV-prevention and treatment, combining research and implementation. Biomedical, public health and sociobehavioral expertise is used for educational programs for adolescents; scaling-up HIV-testing, harm reduction strategies and care for HIV/AIDS in hospital, community and prison; and institutional as well as individual capacity building related to IDU and HIV/AIDS. It is expected that these activities can make a significant contribution to control of HIV-AIDS in the context of injecting drug use in West-Java and Indonesia as a whole.
