Objective: To analyze the association of FLT3-ITD mutation and FLT3 ligand plasma level with one-year survival of Indonesian acute myeloid leukemia (AML) patients.
Methods: A prospective cohort study was conducted to determine the association between FLT-3-ITD mutation and FLT3 ligand plasma level with one-year survival of Indonesian AML patients. In the study, a total of 51 AML patients were obtained from two tertiary hospitals in Indonesia from year 2018 to 2020. Inclusion criteria were de novo AML male and female patients aged ≥18 years old. Exclusion criteria were prior myelodysplastic syndrome and patients that refused to participate in the study. FLT3-ITD genotype of patients was then analyzed using PCR method while FLT3 ligand plasma level was measured using ELISA method. Patients were then followed-up for 1 year or until death occurred with survival as the measured outcome. Association between independent and dependent variable were analyzed by cox regression proportional hazard.
Results: Eleven patients (21.5%) in this study had FLT3-ITD mutation. The median age of AML patients was 45 (18-71) years, and the median blast percentage was 50% (5-87%). After one-year follow-up, 33 (64.7%) patients had died. The median survival of AML patients was 6 months. Univariate analysis showed no association between FLT3-ITD mutation status (HR: 1.051 ; 95% CI: 0.483-2.286; P: 0.901) and FLT3 ligand plasma level (HR: 0.798; 95% CI: 0.347-1.837; p= 0.596), and age (HR: 1.283; 95% CI: 0.575-2.862; p= 0.542) with one-year survival of AML patients, but multivariate analysis showed association between GFR with one-year survival of AML patients in this cohort (HR: 4.053; 95% CI: 1.469-11.183; p= 0.007).
Conclusion: One-year survival of AML patients in Indonesia is not affected by FLT3-ITD mutation and FLT3 ligand plasma level. However, GFR showed association with one-year survival of AML patient in this cohort study.

Background: Radiation segmentectomy (RS) is an alternative potential local curative treatment for selected colorectal liver metastases (CLMs) not amenable to ablation or limited resection.
Purpose: The aim of this study was to evaluate the dosimetric response of low volume CLMs to RS in heavily pretreated patients who are not candidates for resection or percutaneous ablation.
Patients And Methods: This single-center retrospective study evaluated CLMs patients treated with RS (prescribed tumor dose >190 Gy) from 2015 to 2023.

Background: There are few studies in the literature evaluating post-COVID mortality in Brazil, along medium and long term, especially in those who presented severe clinical disease.
Objective: This study aims to investigate the factors associated with post-COVID mortality of severe acute respiratory syndrome (SARS) cases from 2020 to 2023 in Brazil, along medium and long term.
Methods: Retrospective cohort study using notification data of SARS classified as COVID-19 from the Brazilian National Information System, "Sistema de Vigilância Epidemiológica (SIVEP)," during the period 2020 to 2023.

Background And Objectives: Over the last two decades, reductions in cardiovascular (CV) and cerebrovascular events for patients with atrial fibrillation (AF) have been observed, but the non-cardiovascular rates have increased. Early initiation of oral anticoagulation helps reduce AF complications; however, the impact of delayed cardiology care after referral by a Primary Care Physician (PCP) is unknown. The aim of our study is to investigate the association between the elapsed time to cardiology care following a PCP referral and one-year outcomes among patients with AF and analyses gender-specific differences in these outcomes.

Background: Premorbid sarcopenia, osteoporosis, and obesity are epiphenomena that affect survival and functional outcomes in patients with acute ischemic stroke. The effects of preexisting sarcopenia and/or osteopenia on long-term outcome after ischemic stroke were herein prospectively studied.
Methods: Dual-energy x-ray absorptiometry (DeXA), bio-impedance analysis (BIA) and muscle ultrasonography (US) data were prospectively collected within the first 72 hours in 297 consecutive acute ischemic stroke patients (45.
