Impacts of the COVID-19 Pandemic on the CODE ST-Segment Elevation Myocardial Infarction Program: A Quantitative and Qualitative Analysis.

BACKGROUND: The code ST-segment elevation myocardial infarction (STEMI) program is an operational standard of integrated service for STEMI patients carried out by Dr. Cipto Mangunkusumo Hospital. The emerging coronavirus disease 2019 (COVID-19) outbreak brought about many changes in the management of healthcare services, including the code STEMI program. This study aimed to evaluate the healthcare service quality of the Code STEMI program during the COVID-19 pandemic based on the Donabedian concept.  Methods: This was a mixed-methods study using quantitative and qualitative analyses. It was conducted at the Dr. Cipto Mangunkusumo Hospital, a national referral hospital in Indonesia. We compared the data of each patient, including response time, clinical outcomes, length of stay, and cost, from two years between 2018-2020 and 2020-2022 as the pre-COVID-19 code STEMI and COVID-19 Code STEMI periods, respectively. Interviews were conducted to determine the quality of services from the perspectives of stakeholders. RESULTS: A total of 195 patients participated in the study: 120 patients in pre-COVID-19 code STEMI and 75 patients in COVID-19 code STEMI. Our results showed that there was a significant increase in patient's length of stay during the COVID-19 pandemic (4 days vs. 6 days, p < 0.001). Meanwhile, MACE (13% vs. 11%, p = 0.581), the in-hospital mortality rate (8% vs. 5%, p = 0.706), door-to-wire crossing time (161 min vs. 173 min, p = 0.065), door-to-needle time (151 min vs. 143 min p = 0.953), and hospitalization cost (3,490 USD vs. 3,700 USD, p = 0.945) showed no significant changes. In terms of patient satisfaction, patients found code STEMI during COVID-19 to be responsive and excellent. CONCLUSION: The implementation of the code STEMI program during the COVID-19 pandemic revealed that modified pathways were required because of the COVID-19 screening process. According to the Donabedian model, during the pandemic, the code STEMI program's healthcare service quality decreased because of a reduction in efficacy, effectiveness, efficiency, and optimality. Despite these limitations attributed to the pandemic, the code STEMI program was able to provide good services for STEMI patients.

Validity and Reliability Studies of the Indonesian Version of Arrhythmia-Specific Questionnaire in Tachycardia and Arrhythmia (ASTA).

BACKGROUND: The Arrhythmia-Specific Questionnaire in Tachycardia and Arrhythmia (ASTA) was developed in Sweden using English which may pose cultural and language barriers for Indonesian patients. As such, we aimed to translate the original ASTA into Indonesian, then assess its validity and reliability. METHODS: Translation of the ASTA from English to Indonesian was done using forward and backward translation. The final version was then validated with the Short Form-36 (SF-36) questionnaire. Test-retest reliability study was done in a 7-14-day interval. RESULTS: The Indonesian version of ASTA was deemed acceptable by a panel of researchers with Cronbach's α of 0.816 and Intraclass Correlation Coefficient (ICC) ranging from 0.856-0.983. In a comparison to the SF-36, the medication utilization domain was poorly correlated with role limitations due to physical health (r:0.384; p<0.01) and pain (r:-0.317; p<0.05). The arrhythmia-specific symptoms domain was poorly correlated with role limitations due to emotional problems (r:0.271; p<0.05). In addition, the health-related quality of life (HRQOL) domain was poorly correlated with role limitations due to physical health (r:0.359; p<0.01) and emotional problems (r:0.348; p<0.01), also total SF-36 score (r:-0.367; p<0.01). The ASTA total score was poorly correlated with role limitations due to physical health (r:0.37; p<0.01), and emotional problems (r:0.376; p<0.01), also total SF-36 score (r:-0.331; p<0.01). CONCLUSION: The Indonesian version of ASTA has good internal and external validity as well as good reliability. Both the physical and mental domains of ASTA are correlated with role limitations due to emotional problems and SF-36 total score.

Factors Associated with 30-day Major Adverse Cardiovascular Event in Acute Coronary Syndrome Patients with Non-Dialysis Chronic Kidney Disease: A Retrospective Cohort Study.

BACKGROUND: Acute coronary syndrome (ACS) accounts for the majority of ischemic heart disease-related deaths. It is known that ACS patients with chronic kidney disease (CKD) tend to have worse clinical outcomes, including major adverse coronary events (MACE) compared to patients without CKD.  Some studies suggested that several determinant factors may be involved in this condition. Until now, research on determinant factors of MACE in ACS patients with CKD in Indonesia is still limited. Thus, we aimed to investigate the relationship of various factors to MACE in ACS patients with non-dialysis CKD who underwent percutaneous coronary intervention (PCI), in the form of neutrophile leukocyte ratio (NLR) as a factor describing chronic inflammation, left ventricular hypertrophy (LVH) as a factor describing cardiac remodeling, Gensini score may represent coronary severity, whereas GRACE was used to evaluate the severity and clinical risk of ACS patients. METHODS: This study is a retrospective cohort study using secondary data from the medical records of 117 ACS patients who underwent percutaneous coronary intervention (PCI) at Cipto Mangunkusumo General Hospital Jakarta from January 2018 to June 2018 . Patients were classified based on the stage of CKD and assessed for 30-day MACE. Data were recorded on GRACE score, Gensini score, LVH, and neutrophil-lymphocyte ratio (NLR). Analysis of the relationship between these factors was carried out using the chi-square test. RESULTS: Of the 117 patients, 62.3% were STEMI. At the end of hospital treatment, 67.5% were in the normal-stage 2 CKD group, 17.1% in the CKD stage 3a-3b group, and 15.4% in the CKD stage 4-5 group. MACE occurred in 47 (40.2%) patients with 17 (14.5%) dying. There was a significant relationship between GRACE scores and MACE (54.8% MACE at high GRACE scores vs. 32% MACE at low-moderate GRACE scores, p = 0.016, OR: 2,57 CI 95%, 1,18-5,59), while no significant relationship was found for the Gensini score, LVH, and NLR scores even though there was an increase in the proportion of MACE. CONCLUSION: The incidence of MACE is higher than in the previous studies conducted in the same place, i.e. Cipto Mangunkusumo General Hospital, no significant relationship is found in NLR, LVH, and Gensini score with the 30-day MACE of ACS patients with non-dialysis CKD, meanwhile the GRACE score correlates with the 30-day MACE of ACS in non-dialysis CKD patients as is the known theory regarding this score.

Association of leukocyte nadir with complete remission in Indonesian acute myeloid leukemia patients undergoing 7+3 remission induction chemotherapy.

Background: The 7+3 regimen is still the main choice of remission induction chemotherapy in acute myeloid leukemia (AML). Successfully achieving complete remission (CR) and the time required to achieve it determine patient's survival. Hence, bone marrow examination on 14 th day of chemotherapy is recommended to predict CR. However, the examination is invasive and still inaccurate. Methods: A prognostic study with retrospective cohort design was conducted at two central hospitals in Indonesia based on medical record data of AML patients who underwent 7+3 induction chemotherapy from January 1st, 2015, to December 31st, 2019. The association of nadir leukocyte level and the time required to achieve it with CR occurrence was assessed. Results: One hundred and one subjects were recruited with median age 39 years and 55% men. A total of 55.4% subjects achieved CR. Nadir leukocyte level below 200/mcl was the most optimal cut-off point and independently associated with CR (OR 2.48; 95% CI 1.03-5.97) while time required to achieve it was not. Conclusions: The nadir leukocyte level is associated with an increase probability of CR but not for the time required to achieve it in AML patients undergoing 7+3 induction chemotherapy.

Factors Affecting Mortality of Critical Limb Ischemia 1 Year after Endovascular Revascularization in Patients with Type 2 Diabetes Mellitus.

BACKGROUND: Chronic limb ischemia (CLI) is strongly associated with increased mortality in diabetes patients. OBJECTIVE: The aim of this study was to evaluate factors affecting mortality within 1 year after endovascular revascularization in CLI patients. METHODS: This retrospective cohort study was based on medical records from the Integrated Cardiovascular Centre of Dr. Cipto Mangunkusumo National General Hospital, a tertiary care hospital in Jakarta, Indonesia. The study included 199 CLI patients with type 2 diabetes mellitus (T2DM) who underwent endovascular revascularization from January 2008 to June 2018. The patients were followed up for 1 year after endovascular revascularization. Kaplan-Meier and Cox proportional hazard analysis was used to analyze the data. RESULTS: 1-year survival probability was 58.8%. Cox proportional hazard analysis showed that duration of diabetes (HR 3.52; 95% CI 1.34-9.22), anemia (HR 2.59; 95% CI 1.47-4.56), and smoking (HR 2.49; 95% CI 1.46-4.27) were significantly associated with mortality within 1 year after endovascular revascularization. CONCLUSIONS: In T2DM patients with CLI, duration of diabetes, anemia and smoking were associated with a higher risk of mortality within 1 year post endovascular revascularization.

Effects of the COVID-19 pandemic on the management of ST-Segment elevation myocardial infarction in Indonesia: a cohort study.

Background: ST-segment elevation myocardial infarction (STEMI) is a form of acute coronary syndrome with high mortality rate. Management of STEMI should be performed as soon as possible to prevent further damage. With the emergence of coronavirus disease 2019 (COVID-19), it may face obstacles. To overcome those problems, some changes in policy focusing on fibrinolytic therapy in STEMI patients have been applied. This study aimed to identify the effects of COVID-19 in management of STEMI patients in Indonesia. Methods: This retrospective study was conducted in Dr. Cipto Mangunkusumo Hospital (CMH), the national referral center in Indonesia. We compared data between 2018 to 2019 and 2020 to 2021 as before and during COVID-19 pandemic period, respectively. We analyzed the effects of COVID-19 on STEMI patients' visits to hospital i.e., monthly hospital admission and symptoms-to-hospital, management of STEMI i.e., the strategies and time of reperfusion, and clinical outcomes of STEMI patients i.e., major adverse coronary event and mortality. Results: There was a significant statistically reduced mean of monthly hospital admissions from 11 to 7 (p = 0.002) and prolonged duration of symptoms-to-hospital during COVID-19 from 8 to 12 hours (p = 0.005). There was also a decrease in primary percutaneous coronary intervention (PPCI) procedures during COVID-19 (65.2% vs. 27.8%, p<0.001), which was accompanied by an increased number of fibrinolytic (1.5% vs. 9.5%, p<0.001) and conservative therapy (28.5% vs. 55.6%, p <0.01). Moreover, there was also a prolonged duration of diagnosis-to-wire-crossing time (160 vs. 186 minutes, p = 0.005), meanwhile, percentage of urgent PCI, door-to-needle time, and clinical outcomes were not statistically significant. Conclusions: During COVID-19 pandemic, the number STEMI patients declined in monthly hospital admission, delays in symptoms-to-hospital time, changes in type of reperfusion strategy, and delays in PPCI procedures in CMH. Meanwhile, fibrinolytic time and clinical outcomes were not affected.

Factors that Influence 2-Year Progression-Free Survival Among Head and Neck Cancer Patients.

OBJECTIVES: The majority of patients with head and neck cancer (HNC) come to the hospital at advanced stages. This research was conducted to determine the mortality, 2-year progression-free survival (PFS) and factors that influenced PFS of HNC patients. METHODS: A retrospective cohort study was conducted among locally advanced HNC patients who underwent chemoradiation for the first time at RSCM from January 2015 to December 2017. Data were retrieved through medical records. Laboratory data were taken 2-4 weeks prior and 2-4 weeks after chemoradiation. PFS observation started from the first day of chemoradiation until disease progression or death. PFS data were recorded in two groups: ≤ 2 years and > 2 years. The Chi-square test was used for bivariate analysis with the Fischer-exact test as an alternative. Variables will be further tested using multivariate logistic regression tests. RESULTS: Among 216 subjects, there were 103 (47.69%) patients who did not reach overall survival (OS) > 2 years. There were 108 (50%) patients who had PFS > 2 years. Based on the results of multivariate analysis, it was found that smoking, hemoglobin level ≤ 12 g/dl, ECOG (Eastern Cooperative Oncology Group) 1-2, and negative therapeutic response were associated with poor PFS. Hazard ratio (HR) for 2-year PFS for Brinkman index > 250 was 1.36 (95% CI 0.93-2.00; p = 0.02); HR for Hb ≤ 12 g/dl was 1.65 (95% CI 1.13-2.42; p = 0.01); HR for ECOG 1-2 was 4.05 (95% CI 1.49-11.00; p < 0.01); and HR for negative therapeutic response was 2.37 (95% CI 1.43-3.94; p < 0.01). CONCLUSION: Mortality of HNC patients within 2 years is 47.69%, with a 2-year PFS reaching 50%. Cigarette smoking, low hemoglobin levels, poor performance status, and negative therapeutic response (non-responders) negatively affect the 2-year PFS.

Role of Pretreatment Hemoglobin-to-Platelet Ratio in Predicting Survival Outcome of Locally Advanced Nasopharyngeal Carcinoma Patients.

BACKGROUND: The three-year survival rate of locally advanced nasopharyngeal carcinoma (NPC) patients in Indonesia is lower than in other Asian countries. Calculation of hemoglobin-to-platelet ratio (HPR) may become a more practical predictor than the ratios using leukocyte cell components. Yet, no study has been conducted to investigate the potential of HPR in predicting survival outcomes in locally advanced nasopharyngeal cancer patients. OBJECTIVE: To determine the role of pretreatment hemoglobin-to-platelet ratio in predicting the three-year overall survival (OS) of locally advanced NPC. METHOD: A retrospective cohort study followed up on 289 locally advanced NPC patients who had undergone therapy at the Dr. Cipto Mangunkusumo National General Hospital between January 2012 and October 2016. HPR cut-off was determined using ROC. Subjects were classified into two groups according to the HPR value. Kaplan-Meier curve was utilized to illustrate patients' three-year survival, and Cox regression test analyzed confounding variables to yield an adjusted hazard ratio (HR). RESULTS: The optimal cut-off for HPR was 0.362 (AUC 0.6228, 95% CI: 0.56-0.69, sensitivity 61.27%, specificity 60.34%). Of the subjects, 48.44% had HPR ≤ 0.362, and they had a higher three-year mortality rate than those with HPR > 0.362 (50% vs. 31.54%). In bivariate analysis, HPR ≤ 0.362 and age ≥ 60 significantly showed a worse three-year OS (p value = 0.003 and 0.075, respectively). In multivariate analysis, we concluded that a pretreatment HPR ≤ 0.362 was an independent negative predictor of three-year OS in locally advanced NPC patients (adjusted HR 1.82; 95% CI: 1.25-2.65). CONCLUSION: Pretreatment HPR ≤ 0.362 was a negative predictor of three-year OS in locally advanced nasopharyngeal cancer patients.

Cytomegalovirus may influence vascular endothelial health in Indonesian HIV-infected patients after 5 years on ART.

OBJECTIVES: Accelerated atherosclerosis in older HIV-infected patients has been attributed to persistent immune activation and high burden cytomegalovirus (CMV), as demonstrated in transplant recipients and the general population. Here we assess CMV and inflammatory markers linked with vascular health in young adult patients treated in Indonesia. STUDY DESIGN: HIV-infected adults (n = 32) were examined when they began antiretroviral therapy (ART) with < 200 CD4 T-cells/µl (V0) and after 60 months (V60). Age-matched healthy controls (HC, n = 32) were assessed once. METHODS: Flow Mediated Dilatation (FMD) was assessed by ultrasound on brachial arteries at V60 and in HC. Plasma markers of immune activation and endothelial activation, and CMV antibodies (lysate, gB, IE-1) were assessed in all samples. Results were assessed using bivariate (non-parametric) and multivariable analyses. RESULTS: Levels of inflammatory biomarkers and CMV antibodies declined on ART, but the antibodies remained higher than in HC. FMD values were similar in patients and HC at V60. In HIV patients, levels of CMV lysate antibody correlated inversely (r = - 0.37) with FMD. The optimal model predicting lower FMD values (adjusted R2 = 0.214, p = 0.012) included CMV lysate antibodies and chondroitin sulphate. In HC, levels of sTNFR correlated inversely with FMD (r = - 0.41) and remained as a risk factor in the optimal multivariable model, with CMV glycoprotein-B (gB) antibody predicting a healthier FMD (adjusted R2 = 0.248, p = 0.013). CONCLUSIONS: Higher levels CMV antibodies optimally predict vascular health measured by FMD in HIV patients. However in healthy controls, sTNFR marks risk and CMV gB antibody may be protective.

Single-centre, double-blind, randomised, parallel-group, superiority study to evaluate the effectiveness of general anaesthesia and ultrasound-guided transversus thoracis muscle plane block combination in adult cardiac surgery for reducing the surgical stress response: clinical trial protocol.

INTRODUCTION: Adult open-heart surgery is a major surgery that causes surgical stress response and activation of the immune system, contributing further to postoperative complications. Transversus thoracis muscle plane block (TTPB) may potentially benefit in reducing the surgical stress response. This study aims to know the effectiveness of preoperative TTPB in adult open-heart surgery for reducing the surgical stress response. METHODS AND ANALYSIS: This study is a prospective, double-blind, randomised control trial comparing the combination of general anaesthesia and TTPB versus general anaesthesia only in adult open-heart surgery. Forty-two eligible subjects will be randomly assigned to the TTPB group or control group. The primary outcomes are the difference between the two groups in the means of postoperative cortisol and interleukin-6 plasma levels at 24 hours and 48 hours after cardiac intensive care unit admission. The secondary outcomes are the difference between the two groups in the means of total 24-hour postoperative morphine consumption and time of first postoperative patient-controlled analgesia (PCA) dose. ETHICS AND DISSEMINATION: The study protocol and informed consent forms have been reviewed and approved by the Ethics Committee of Faculty of Medicine Universitas Indonesia/Dr. Cipto Mangunkusumo Hospital. The result will be released to the medical community through presentation and publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT04544254.

Predictive scoring systems for in-hospital mortality due to acutely decompensated liver cirrhosis in Indonesia.

BACKGROUND: Acutely decompensated liver cirrhosis is associated with high medical costs and negatively affects productivity and quality of life. Data on factors associated with in-hospital mortality due to acutely decompensated liver cirrhosis in Indonesia are scarce. This study aims to identify predictors of in-hospital mortality and develop predictive scoring systems for clinical application in acutely decompensated liver cirrhosis patients. METHODS: This was a retrospective cohort study using a hospital database of acutely decompensated liver cirrhosis data at Cipto Mangunkusumo National General Hospital, Jakarta (2016-2019). Bivariate and multivariate logistic regression analyses were performed to identify the predictors of in-hospital mortality. Two scoring systems were developed based on the identified predictors. RESULTS: A total of 241 patients were analysed; patients were predominantly male (74.3%), had hepatitis B (38.6%), and had Child-Pugh class B or C cirrhosis (40% and 38%, respectively). Gastrointestinal bleeding was observed in 171 patients (70.9%), and 29 patients (12.03%) died during hospitalization. The independent predictors of in-hospital mortality were age (adjusted OR: 1.09 [1.03-1.14]; p = 0.001), bacterial infection (adjusted OR: 6.25 [2.31-16.92]; p < 0.001), total bilirubin level (adjusted OR: 3.01 [1.85-4.89]; p < 0.001) and creatinine level (adjusted OR: 2.70 [1.20-6.05]; p = 0.016). The logistic and additive scoring systems, which were developed based on the identified predictors, had AUROC values of 0.899 and 0.868, respectively. CONCLUSION: The in-hospital mortality rate of acutely decompensated liver cirrhosis in Indonesia is high. We have developed two predictive scoring systems for in-hospital mortality in acutely decompensated liver cirrhosis patients.

Performance of Identification of the Seniors At Risk (ISAR) tool and Triage Risk-Screening Tool (TRST) for frail elderly emergency room patients.

OBJECTIVE: This objective of this study was to measure the performance of the identification of the seniors at risk (ISAR) tool and triage risk-screening tool (TRST) for frailty screening in elderly emergency room (ER) patients. METHODS: A cross-sectional study involving subjects aged 60 years or older was conducted at Cipto Mangunkusumo General Hospital ER from September-November 2018. Frailty was defined by the Forty Item Frailty Index (FI-40). The ISAR and TRST performance were measured as sensitivity, specificity, positive and negative predictive value (PPV and NPV), positive and negative likelihood ratio (LR+ and LR-) and the area under the curve (AUC). RESULTS: A total of 471 subjects were examined, of which 300 (63.7%) were in the 60-69-year-old subgroup with a median age of 66 years and an age range of 60-95 years. There were 262 (55.6%) male subjects and 445 (94.5%) were non-trauma patients. According to the FI-40, 386 (82%) were classified as frail. ISAR and TRST showed a sensitivity of 87.6% vs 93.8%, a specificity of 58.8% vs 43.5%, a PPV of 90.6% vs 88.3%, an NPV of 51% vs 60.7%, a LR+ of 2.13 vs 1.66 and a LR- of 0.21 vs 0.14, respectively. Both had similar AUCs of 0.8 (95% CI: ISAR [0.76, 0.86] and TRST [0.75, 0.86], p = 0.91). CONCLUSIONS: ISAR and TRST showed outstanding frailty-screening results among elderly ER patients.

The Influence of New-Onset Atrial Fibrillation After Coronary Artery Bypass Grafting on Three-Year Survival.

BACKGROUND: new-onset atrial fibrillation after coronary artery bypass grafting (CABG) is a common postoperative complication. This arrhytmia considered as temporary phenomenon which the majority are converted back to sinus rhytm when the patients discharged from the hospital. Despite its transience, those arrhytmia can recur and increasing the long term mortality. This study aims to determine the role of new-onset atrial fibrillation after CABG in three year survival. METHODS: retrospective cohort study using survival analysis of patients who underwent coronary artery bypass grafting since January 2012 to December 2015 at Cipto Mangunkusumo Hospital. Patients with atrial fibrillation before surgery, who had surgery without cardiopulmonary bypass machine, and who died in 30 days after surgery are excluded. Subjects are divided into two category based of the presence of new-onset atrial fibrillation after CABG and the mortality status is followed up until 3 years post-surgery. The Kaplan-Meier curve is used to determine the three-year survival of the patients who had new-onset atrial fibrillation after CABG and Cox regression test used as multivariate analysis with confounding variables in order to get adjusted hazard ratio (HR). RESULTS: new-onset atrial fibrillation after-CABG occurred in 29,59% patients. Patients with new-onset atrial fibrillation after CABG have higher three-year mortality (15,52% vs 3,62%) and significantly decreases three-year survival (p=0,008; HR 4,42; 95% CI 1,49-13,2). In multivariate analysis, new-onset atrial fibrillation after CABG is an independent factor of the three-year survival decline (adjusted HR 4,04; 95% CI; 1,34-12,14). CONCLUSION: new-onset atrial fibrillation after CABG independently decreases three-year survival.

ST-Elevation Myocardial Infarction: A Simulation Case for Evaluation of Interprofessional Performance in a Hospital.

INTRODUCTION: Interprofessional collaboration between units in a hospital is essential in order to reach desired time for primary percutaneous intervention (PCI) in acute ST-Segment Elevation Myocardial Infarction (STEMI) cases. We developed a simulation to engage various medical and nonmedical staff in interprofessional and interunit team collaboration. METHOD: We used a scenario in this simulation. Beginning in the emergency department, it detailed a 50-year-old male presenting with progressive chest pain since 7 hours before admission. The emergency team directly examined the patient, and STEMI diagnosis was made, followed by sending the patient to the cardiac catheterization laboratory to undergo primary PCI. A resuscitation kit was required for the simulation. An evaluation sheet was prepared to evaluate every step of patient management. Three judges observed the simulation. At the end of the simulation, debriefing was done, and recommendation for the simulation was discussed. Besides medical activities during patient management, interprofessional communication, administration activities, consultations, and handover process were also evaluated. RESULTS: The team achieved the appropriate door-to-electrocardiogram (ECG) time in 8 minutes, but overall target was delayed since door-to-skin puncture time was reached in 110 minutes. Some factors that contributed to these conditions were long waiting time during patient admission, several attempts for telephone consultation to the cardiologist, and prolonged admission process in the cardiac catheterization laboratory. CONCLUSIONS: The simulation was well received by both participant and our institution, stating that it is a valuable resource for developing interdisciplinary learning program. This simulation also contributed to the development of the clinical pathway, STEMI protocol, in our institution.

Factors Associated with Mortality of Intensive Care Unit Patients with Acute Kidney Injury at Cipto Mangunkusumo National Central General Hospital.

BACKGROUND: the incidence of acute kidney injury (AKI) in intensive care units is associated with increased mortality, post AKI morbidity and high treatment costs. Research on factors related to mortality of AKI patients in intensive care units in Indonesia, especially Cipto Mangungkusumo General Hospital has never been done. This study aims to determine the prevalence of AKI, mortality rate of AKI patients, and the factors associated with increased mortality of AKI patients in intensive care units in ICU Cipto Mangunkusumo General Hospital. METHODS: this is a retrospective cohort study of all patients diagnosed with AKI in the intensive care unit at Cipto Mangunkusumo General Hospital, January 2015 - December 2016. An analysis of bivariate relationships with multvariate with STATA Statistics 15.0 between age > 60 years, sepsis, use of ventilator, ventilator duration, dialysis, oligoanuria, and APACHE II scores at admission with mortality. RESULTS: the prevalence of AKI patients in the intensive care unit was 12.25% (675 of 5511 subjects) and 220 subjects (32.59%) of the 675 analyzed subjects died in the intensive care unit. Factors related to increased mortality in multivariate analysis were sepsis (OR 6,174; IK95% 3,116-12,233), oligoanuria (OR 4,173; IK95% 2,104-8,274), use of ventilator (OR 3,085; IK95% 1,348-7,057), (scores APACHE II at admission) 1/2 [OR 1,597; IK95% 1.154-2.209], and the duration of the ventilator (OR 1.062; IK95% 1.012-1.114). CONCLUSION: the prevalence of AKI patients and their mortality rate in the intensive care unit of Cipto Mangunkusumo General Hospital obtained 12.25% and 32.59%. Sepsis, oligoanuria, ventilators (APACHE II score at admission) 1/2, and ventilator duration are factors that are significantly associated with increased mortality of AKI patients in intensive care units.

Cardiopulmonary Bypass Alone Does Not Cause Postoperative Cognitive Dysfunction Following Open Heart Surgery.

BACKGROUND: Postoperative cognitive dysfunction (POCD) is commonly observed following cardiac surgery. The utilization of cardiopulmonary bypass (CPB) is associated with many possible mechanisms to cause POCD. However, there is no evidence confirming that CPB alone is the cause of POCD. OBJECTIVES: The current study aimed at evaluating several factors suspected to cause POCD following cardiac surgery in Cipto Mangunkusumo Hospital, Jakarta, Indonesia. METHODS: The current prospective cohort study was conducted on 54 patients who were candidates for cardiac surgery. The assessment of memory, attention, and executive functions was performed by neuropsychological tests, before and after the surgery. Cognitive decline was defined as a 20% decrease in cognitive function in at least one of the tests. Inclusion criteria were adults spokeing Bahasa Indonesia fluently, literate, and giving consent to participate in the study. The analyzed risk factors included age, diabetes, educational level, duration of aortic cross clamp, and duration of cardio-pulmonary bypass. RESULTS: POCD occured in 40.7% of subjects that underwent cardiac surgery using cardiopulmonary bypass. Age was the only influential factor through bivariate test and logistic regression analysis (P = 0.001). The current study conducted a logistic regression test on age variable; the obtained result indicated an increasing trend of POCD in accordance with age group. CONCLUSIONS: Durations of CPB, cross clamp, diabetes, and educational level were not the main risks of POCD. Old age was a significant predictor to POCD.

The Influence of Hyperglycemia at Admission on In-hospital Arrhythmia Patients with Acute Coronary Syndrome.

AIM: to determine the incidence of in-hospital arrhythmias in patients with acute coronary syndrome (ACS) and to determine the influence of hyperglycemia at admission (HA) on in-hospital arrhythmias complicating ACS. METHODS: a retrospective cohort study was conducted using secondary data from medical records of patients with ACS who were admitted to ICCU RSCM, between January 1st-December 31st, 2014. Hyperglycemia at admission was defined when the blood glucose level at admission was >140 mg/dL. The in-hospital arrhythmias encompassed atrial arrhythmia, supraventricular tacchycardia (SVT), high grade AV block (HAVB), and ventricular arrhythmia, during the first seven days of hospitalization. RESULTS: there were 232 subjects in this study. The prevalence of HA was 50.43%. The incidence of in-hospital arrhythmia was 21.55% (95% CI 16.26-26.84). In bivariate analysis, there was significant association between HA and in-hospital arrhythmia (RR 1.75; 95% CI 1.04-2.93). There were no association between type of ACS, diabetes mellitus (DM), obesity, and hypertension, with the in-hospital arrhythmias. In multivariate analysis, the adjusted OR of HA was 2.85 (95% CI 1.35-6.02), and DM was the confounding variable. CONCLUSION: the incidence of in-hospital arrhythmias in patients with ACS was 21.55% (95% CI 16.26-26.84). Hyperglycemia at admission may increase the risk of in-hospital arrhythmia in patients with ACS.

Pathophysiology of critical ill patients: focus on critical oxygen delivery.

Critical ill patients experience acute physiological changes because the body cannot fulfill the oxygen demand to perform normal aerobic metabolism. Factors determining oxygen delivery include cardiac output, hemoglobin, and oxygen saturation. Incapability to fulfill adequate oxygen of the body to produce adenosine triphosphate (ATP) may occur due to decreased oxygen delivery and/or increased oxygen consumption. A condition in which oxygen consumption becomes very dependent on oxygen delivery is called critical oxygen delivery. Parameters to evaluate the adequate oxygen delivery to meet the oxygen consumption are central vein oxygen saturation (SvO2), serum lactate, oxygen extraction ratio (O2ER). A comprehension about oxygen delivery and consumption is very important to overcome tissue hypoxia and various factors in critical ill patients.

Correlation between free thyroxin levels and left ventricular ejection fraction in Graves' disease (preliminary study).

AIM: to determine the correlation between free thyroid hormone level and left ventricular ejection fraction in newly diagnosed Graves' patients. METHODS: this is a preliminary study with an initial cross-sectional design using free thyroxine level as a parameter of thyroid hormone state and left ventricular ejection fraction (LVEF) as a parameter of left ventricular systolic function. Free thyroxine level was measured in the laboratory and the LVEF was assessed by Simpson's methods of echocardiography study. RESULTS: ten patients (7 men and 3 women; age 18-52 years old) were studied. Their average of fT4 was 5.75 (SD 0.96) ng/dL and their average of LVEF was 70.57 (SD 4.50)%. There was positive correlation coefficient between free thyroxine level and left ventricular ejection fraction (r=0.711, p=0.021) in newly diagnosed Graves' patients. CONCLUSION: in this study strong positive correlation was found between free thyroxine (fT4) and left ventricular ejection fraction (LVEF) in newly diagnosed Graves' patients.

Internet searching on internal medicine literature.

Internet technology for distributing information enormously supports the development of medical knowledge. Various medical resources on the internet are very helpful for the doctors' self-improvement; either on education, research, or health care application. Famous medical journals have made their online version, which can be accessed at any time and anywhere. However, there are extremely enourmous information that could be retrieved, so that the doctors should have appropriate strategy or measure to obtain the literature effectively and efficiently.
