Abstract

Malaria adalah infeksi parasit protozoa dari genus Plasmodium yang menyerang sel darah merah. Kasus  malaria banyak ditemukan di wilayah subtropis dan tropis dan dapat mengakibatkan kematian.  Penegakan diagnosis malaria perlu diperhatikan untuk melihat keakuratan metode yang digunakan guna mencegah terjadinya kesalahan dalam pemeriksaan laboratorium. Metode yang dapat digunakan dalam deteksi malaria yaitu dengan pemeriksaan mikroskopis, Polymerase Chain Reaction (PCR), dan Rapid Diagnostic Test (RDT). Kombinasi dari berbagai metode dapat meningkatkan akurasi diagnosis malaria. Penulisan artikel ini bertujuan untuk mengkaji peran berbagai metode pemeriksaan laboratorium dalam mendeteksi malaria dan menganalisis perbandingan metode mikroskopis, PCR dan RDT.

Abstract

Background: Acute Lymphoblastic Leukemia (ALL) remains the most common pediatric cancer, yet survival outcomes vary widely across age groups. In Indonesia, comprehensive data on ALL survival rates are sparse, particularly for adolescents who often fare worse than younger children. The underlying factors contributing to the difference in adolescent survival rates still need to be fully understood. This study aimed to evaluate and compare the survival rates of children and adolescents with ALL treated at Dharmais Cancer Hospital.Method: We conducted a retrospective cohort analysis of 94 ALL patients, including 37 adolescent patients and 71 patients with B-lineage ALL. All patients with ALL from 2021 to 2023 were identified. Children aged 1–18 years, diagnosed with ALL based on bone marrow results and not yet treated, are included in the study. Patients were stratified by risk stratification (Standard Risk [SR] vs. High Risk [HR]), lineage (B-lineage vs. T-lineage), and age group (children under 10 vs. adolescents 10 years and above). The survival curve was analyzed using the KaplanMeier method, and the log-rank test was used to assess and compare survival across groups.Results: The overall survival (OS) rate for ALL patients was 49.5%. Adolescents had a significantly lower OS rate of 23.2% compared to children. SR patients exhibited an OS rate of 95.7%, while HR patients had a 33.3%. B-cell lineage had a higher OS rate (59.8%) than T-cell lineage (15.9%). In B-cell ALL, OS was 61.4% in children but only 28.1% in adolescents. Conclusion: The survival rate for adolescents with acute lymphoblastic leukemia (ALL) is significantly lower than that of children, influenced by risk stratification, lineage, and age. Further research is needed to identify these risk factors through genetic and molecular analyses.Conclusion: The survival rate for adolescents with acute lymphoblastic leukemia (ALL) is significantly lower than that of children, influenced by risk stratification, cell type, and age. Unexplained factors, including lineage differences, remain a challenge in adolescents. Further research into genetic and molecular factors is essential to enhance treatment precision and improve survival rates for ALL patients in Indonesia, especially adolescents.Keywords: Overall Survival, Leukemia, Adolescent ALL, Stratification

Abstract

Background Copy Number Alterations (CNAs) are changes in DNA structure that lead to gain or loss of copies of DNA sections in the genome. They correlate with unfavorable prognostic outcomes in pediatric leukemia, influencing treatment resistance, relapse rates, and overall survival. Identifying high-risk patients with a likelihood of CNA positivity is essential for understanding its association with clinical characteristics and laboratory findings. Since routine CNA testing is costly, recognizing simple clinical and laboratory markers that predict CNA presence can help focus screening efforts, enabling more efficient risk stratification and prognosis assessment in acute leukemia Objective To describe the characteristics and analyze for associations between CNA, clinical characteristics, and laboratory findings in pediatric ALL patients. Methods This cross-sectional observational study included B-cell acute lymphoblastic leukemia (ALL) patients from three hospitals, excluding those above 18 years. Data collected encompassed demographics, clinical features, and laboratory results. We performed multiplex ligation-dependent probe amplification (MLPA) testing to identify CNA positivity. Results From January to December 2019, there were 74 pediatric ALL patients incuded in our study; 26 of them had positive results and the remaining 48 had negative results. CNA-positive status was commonly found in subjects aged ? 5 years (38.6%), while CNA-negative status was highest in patients aged ? 10 years (72.7%). CNA-positive status was significantly higher in patients with lymphadenopathy, lower hemoglobin level (7.73 g/dL), and lower platelet level (52,019/µL) (P<0.05). Conclusion Patients with lymphadenopathy, lower hemoglobin, and lower platelet levels are more likely to test positive for CNA. However, more research is needed to fully understand the implications of this finding and its potential impact on patient care.

Abstract

Promoter methylation of the hTERT gene in blood DNA has been proposed to be an epigenetic molecular clock because it is negatively correlated with ageing. Saliva is an alternative source of DNA because it contains buccal cells. Currently, the correlation of hTERT promoter methylation and ageing using saliva is not known. This study aimed to determine: first, the correlation between hTERT promoter methylation and ageing in saliva, as a source of non-invasive DNA sampling, instead of blood was determined. Second, the influence of sex on the methylation of the hTERT promoter in ageing was evaluated. A cross-sectional study design was used, and 119 subjects were recruited, consisting of 25 children (1-5 y.o), 42 teens (17-19 y.o), 16 adults (20-50 y.o), and 36 elderly (60 to 84 y.o). Promoter methylation of the hTERT of extracted DNA was determined using the MSRE (methyl-specific restriction enzyme) method. The relationship between age and the percentage of hTERT methylation was assessed using the Pearson test. The percentage of hTERT methylation in saliva DNA was negatively correlated with age r= -0.4305 (p-value <0.05). Negative correlation was also found in men (r= -0.376) and women (r=-0.43). Negative correlation between hTERT and ageing has been confirmed in saliva as a noninvasive sampling method. The benefit of this research in ethical and social considerations may encourage a greater participation in ageing research, particularly in underprivileged communities, thus democratising access to scientific advancements in longevity studies.

Abstract

Introduction: The ongoing SARS-CoV-2 pandemic has profoundly emphasized the pressing need for accurate and reliable diagnostic procedures. Given the potential health risks associated with nasopharyngeal swabs, there has been growing interest in seeking alternative diagnostic mediums. In this context, our study delved into evaluating saliva as a potential diagnostic tool, simultaneously assessing its efficiency in relation to patient demographics and their exhibited clinical symptoms. Methods: Spanning from May to December 2020, we conducted a comprehensive cross-sectional analysis. We meticulously examined medical records to gather insights on patient characteristics, existing health conditions, onset of symptoms, clinical manifestations, and compared the results obtained from both salivary and nasopharyngeal RT-PCR tests for SARS-CoV-2. Results: Among the individuals suspected of SARS-CoV-2 infection, the mean age stood at 52.4 years, with males representing 60.3% of this group. Interestingly, a significant 76.9% reported underlying health conditions, predominantly hypertension and diabetes. The most commonly reported symptoms encompassed respiratory challenges, notably coughing and shortness of breath, succeeded by symptoms like nausea, fever, and a general sense of fatigue. The performance of saliva tests, in terms of accuracy, appeared to be significantly influenced by the timing of symptom emergence. Conclusion: The RT-PCR tests utilizing saliva samples demonstrated considerable promise, especially during the early stages of symptom manifestation, providing a reliable alternative to traditional nasopharyngeal swabs. The findings suggest a superior diagnostic sensitivity when utilizing saliva during the initial phases of a SARS-CoV-2 infection.
