The treatment of acute lymphoblastic leukemia (ALL) has dramatically changed over the past three decades. However, relapsed and/or refractory ALL still remains with a very low survival and high morbidity associated with its treatment. Here, we will review the outstanding progress that has been made in the treatment of relapsed and/or refractory ALL and discuss future directions and challenges that require further investigation.

Standardized phase angle (SPhA) is a tool used to estimate body composition and cell membrane integrity. Standardized phase angle has been shown to predict survival in solid malignancies and hematopoietic stem cell transplant patients. We investigated the predictive value of SPhA on 60‐day mortality, overall survival (OS), and length of hospital stay (LHS) for adults with acute myelogenous and lymphoblastic leukemia (AML and ALL). Consecutive patients ≥18 years with newly diagnosed acute leukemia receiving intensive chemotherapy were enrolled. Phase angle measurements were taken on day 1 of therapy for all patients and on the day of nadir marrow for AML patients. Measurements were standardized by BMI, gender, and age to calculate the SPhA. The difference between SPhA at nadir bone marrow compared to day 1 of induction was used to calculate change in SPhA. A cutoff of 25th percentile was used to dichotomize baseline SPhA. Among 100 patients, 88% were AML, 56% were female, and mean age was 59 years. Though not statistically significant, OS by Kaplan‐Meier analysis was shorter for those below the 25th percentile SPhA compared to those above (median OS: 11.0 months vs 19.5 months; P = .09). Lower baseline SPhA was associated with increased incidence of 60‐day mortality in univariable (odds ratio [OR] = 5.25; 1.35, 20.44; P = .02) but not multivariable analysis (OR = 3.12; 0.67, 14.48; P = .15) adjusted for age, creatinine, and cytogenetics. Increased change in SPhA was associated with worse OS (hazard ratio = 1.15; 1.00,1.33; P = .05) in multivariable analysis. Standardized phase angle is a rapid, noninvasive, and objective measure that may be used to inform risk stratification.

Objectives: The goals of this pilot cross-sectional study were to determine the feasibility of and begin measuring the effect of religious institution affiliation on human immunodeficiency virus (HIV) clinical outcomes in the southern United States, a region marked by later initiation of antiretroviral therapy, higher HIV-related morbidity, and higher mortality rates than people living with HIV...

Hematologic malignancies, including leukemias, lymphomas, and multiple myeloma, are diseases of older adults (age ≥ 60 years). Treatment decisions in older adults with cancer are heavily influenced by patient fitness: the ability of an individual patient to tolerate the off-target effects of anti-cancer therapy. Sarcopenia, defined as low muscle mass and strength, is increasingly recognized as an important marker of fitness. Furthermore, sarcopenia is known to be modifiable with nutrition and exercise interventions in older adults without cancer, but such evidence is limited for patients with cancer. Much of the literature on sarcopenia in older adults with cancer has focused on patients with solid tumors. However, there is an increasing body of literature on the impact of sarcopenia in older adults with hematologic malignancies. In this comprehensive review, we attempt to (i) describe the most up-to-date diagnostic criteria and diagnostic approach to sarcopenia, (ii) summarize the prognostic impact of sarcopenia among older adults with hematologic malignancies, (iii) discuss the proposed mechanisms of sarcopenia and its pathogenesis, (iv) review the evidence for interventions targeting sarcopenia, and (v) provide future directions for the advancement of sarcopenia management among older adults with hematologic malignancies.
