Mapping the Grounds for Mortalities in Acute Myeloid Leukemia Through Registry Analyses: A Retrospective Cohort Study of Children, Adolescents, and Young Adults Patients.

Background: Our objective was to identify non-malignant factors that contribute to mortality in children, adolescents and young adults, aiming to improve patient follow-up and reduce mortality rates to achieve better survival outcomes. Methods: We analyzed 8,239 acute myeloid leukemia (AML) cases diagnosed between 2000 and 2019 in the USA. Using version 8.4.0.1 of the Surveillance, Epidemiology, and End Results (SEER)*Stat software, we calculated the standardized mortality ratios (SMRs) and 95% confidence intervals (CIs) for each cause of death. Results: Out of the 3,165 deaths observed in the study population, the majority (2,245;70.9%) were attributed to AML itself, followed by non-AML cancers (573; 18.1%) and non-cancerous causes (347; 10.9%). Conclusions: Patients with AML are at a higher risk of developing other types of cancer and granulocyte deficiencies, which increases the risk of death from non-cancerous causes such as infections. Moreover, treatment for AML carries the risk of cardiac problems. AML is commoner in males than females.

Relation between erythropoietin resistance and metabolic syndrome in hemodialysis patients: A multicentric propensity score matched analysis.

Erythropoietin (EPO) resistance is frequently reported in hemodialysis (HD) patients. Metabolic syndrome (MetS) is a common biochemical condition that comprises central obesity, dyslipidemia, hypertension, and hyperglycemia. The present study aimed to assess the relation between MetS and EPO resistance in HD patients. The present multicentric study included 150 patients with EPO resistance and 150 patients without EPO resistance. Short-acting EPO resistance was diagnosed if the erythropoietin resistance index is ≥1.0 IU/kg/gHb. Comparison between patients with EPO resistance and patients without resistance revealed that the former group had significantly higher body mass index, lower hemoglobin levels, lower albumin levels, higher ferritin levels, and higher high-sensitivity C-reactive protein (hsCRP) levels. In addition, patients in the EPO resistance group had significantly higher frequency of MetS (75.3% vs 38.0%, p < 0.001) and higher number of MetS components (2.7 ± 1.3 vs 1.8 ± 1.6, p < 0.001). Multivariate logistic regression analysis identified lower albumin levels (OR (95% CI): 0.072 (0.016-0.313), p < 0.001), higher ferritin levels (OR (95% CI): 1.05 (1.033-1.066), p< 0.001), higher hsCRP levels (OR (95% CI): 1.041 (1.007-1.077), p = 0.018), and MetS (OR (95% CI): 36.68 (2.893-465.05), p = 0.005) as predictors of EPO resistance in the studied patients. The present study identified MetS as a predictor of EPO resistance in HD patients. Other predictors include serum ferritin, hsCRP, and albumin levels.

Serum Endocan Levels and Subclinical Atherosclerosis in Patients with Chronic Kidney and End-Stage Renal Diseases.

Results: HD and CKD groups had significantly higher endocan levels when compared with control group (median (IQR): 519.0 (202.3-742.0) versus 409.0 (245.3-505.3) and 273.0 (168.0-395.5) ng/L, respectively). Also, HD patients had significantly higher endocan levels when compared with CKD levels. HD patients had significantly higher carotid intima-media thickness (CIMT) when compared with CKD patients (median (IQR): 0.80 (0.80-0.90) versus 0.75 (0.73-0.75) mm, p < 0.001). HD patients had significantly higher frequency of SCA when compared with CKD patients (46.7% versus 13.3%, p=0.005). Patients with SCA had significantly higher hsCRP (median (IQR): 36.5 (26.8-43.5) versus 24.0 (15.8-29.0) mg/dl) and endocan levels (697.0 (528.3-974.8) versus 222.5 (158.8-565.8) ng/L) when compared with patients without SCA. ROC curve analysis of endocan for identification of SCA in HD patients showed that at a cutoff of 380.5 ng/L, endocan has an AUC of 0.862 with a sensitivity and specificity of 92.9% and 68.7%, respectively. Conclusions: Serum endocan levels are related to SCA in HD patients. In addition, it is associated with the hyperinflammatory state in those patients.

COVID-19 Booster Vaccine Hesitancy among Hemodialysis Patients in Saudi Arabia Using the Health Belief Model: A Multi-Centre Experience.

OBJECTIVE: Vaccination hesitance for the COVID-19 booster dosage among hemodialysis patients is an important barrier in reducing morbidity and mortality linked to COVID-19 infection. Hence, this study aimed to explore the predictors of the third (booster) dose of COVID-19 vaccine intention among CKD patients on hemodialysis from the Kingdom of Saudi Arabia (KSA). METHODS: This study was a multi-center cross-sectional study conducted at four dialysis centers in KSA from 13 February 2022 to 21 June 2022. The data was collected by the nephrologist in charge of the unit using a structured study questionnaire, which consisted of four parts; socio-demographic and clinical variables, questions about COVID-19 infection and subjective assessment of health state, COVID-19 booster dose vaccination intention and confidence in vaccines and preferences, and a health belief model. The study population consisted of 179 hemodialysis patients. RESULTS: Participants in the study had conflicting health beliefs about their vulnerability to COVID-19 infection and the severity of the COVID-19 infection. Study participants expressed positive health beliefs about the advantages of the COVID-19 booster dose, and reported less perceived obstacles in receiving the vaccine. The influence of cues on action among the study population was high. A total of 140 (78.2%) hemodialysis patients expressed their intention to receive the COVID-19 booster dose. Patients who reported poor health in the self-rating of their health status had a substantially higher definite intention to take the COVID-19 booster dose, according to the chi-square test (11.16, df = 3, p = 0.01). There was a significant association between the constructs in the HBM model and COVID-19 vaccine (booster) intention. Marital status (OR = 1.67, CI 1.07-2.58) was found to be the strongest predictors of a definite intention to receive a COVID-19 booster dose. Confidence in the locally manufactured vaccine (OR = 0.33, CI 0.17-0.60), education (OR = 0.62, CI 0.41-0.93), and rating of health status (OR = 0.43 CI 0.25-0.74) were the strongest significant correlates of having no definite intention to take the COVID-19 vaccination. CONCLUSIONS: HBM constructs were found to be significantly associated with vaccination intention, which can be considered while planning policies to promote COVID-19 booster vaccination among hemodialysis patients. The study results could be utilized in drafting policies to improve COVID-19 booster dose vaccination uptake among hemodialysis population.
