Insulin resistance during androgen deprivation therapy in men with prostate cancer.

Background: Androgen deprivation therapy (ADT) in prostate cancer (PCa) has been associated with development of insulin resistance. However, the predominant site of insulin resistance remains unclear.

Methods: The ADT & Metabolism Study was a single-center, 24-week, prospective observational study that enrolled ADT-naive men without diabetes who were starting ADT for at least 24 weeks (ADT group, n = 42).

Defining the Educational Needs for a Community-Based Hematology/Oncology Career: A National Needs Assessment.

Purpose: Little is known about the specific needs during training for hematology/oncology providers practicing in community-based settings. We conducted a national survey of hematologists/oncologists employed in community or academic-community hybrid settings to delineate their educational needs.

Methods: An electronic questionnaire was developed and distributed nationally through professional organizations.

Training Hematologists/Oncologists for the Academic-Community Hybrid: Creating a Fellowship Framework for the Future.

Purpose: Conventional hematology/oncology fellowship training is designed to foster careers in academic practice through intensive exposure to clinical and laboratory research. Even so, a notable proportion of graduating fellows opt to pursue a clinically focused career outside the realm of academic medicine. Given the corresponding shortage of oncologists in nonurban and rural settings, improving the representation of hematologists/oncologists in the community setting is a national priority.

Lieb-Robinson Bound and the Butterfly Effect in Quantum Field Theories.

As experiments are increasingly able to probe the quantum dynamics of systems with many degrees of freedom, it is interesting to probe fundamental bounds on the dynamics of quantum information. We elaborate on the relationship between one such bound-the Lieb-Robinson bound-and the butterfly effect in strongly coupled quantum systems. The butterfly effect implies the ballistic growth of local operators in time, which can be quantified with the "butterfly" velocity v_{B}.

Holographic Complexity Equals Bulk Action?

We conjecture that the quantum complexity of a holographic state is dual to the action of a certain spacetime region that we call a Wheeler-DeWitt patch. We illustrate and test the conjecture in the context of neutral, charged, and rotating black holes in anti-de Sitter spacetime, as well as black holes perturbed with static shells and with shock waves. This conjecture evolved from a previous conjecture that complexity is dual to spatial volume, but appears to be a major improvement over the original.

Contract research organizations in oncology clinical research: Challenges and opportunities.

Contract research organizations (CROs) represent a multibillion dollar industry that is firmly embedded in the contemporary clinical trial process. Over the past 30 years, and especially within the last decade, the reach of CROs has extended to service all phases of drug trials in an increasingly global research environment. The presence of CROs is particularly noticeable in medical oncology because of the large number of investigational compounds developed to treat cancer that are currently undergoing testing in human subjects.

Diagnosing Chaos Using Four-Point Functions in Two-Dimensional Conformal Field Theory.

We study chaotic dynamics in two-dimensional conformal field theory through out-of-time-order thermal correlators of the form ⟨W(t)VW(t)V⟩. We reproduce holographic calculations similar to those of Shenker and Stanford, by studying the large c Virasoro identity conformal block. The contribution of this block to the above correlation function begins to decrease exponentially after a delay of ~t_{*}-(β/2π)logβ^{2}E_{w}E_{v}, where t_{*} is the fast scrambling time (β/2π)logc and E_{w},E_{v} are the energy scales of the W,V operators.

Outlook and Management of Patients with Myelodysplastic Syndromes Failed by Hypomethylating Agents.

The DNA hypomethylating agents (HMAs) azacitidine and decitabine are currently the most frequently administered disease-modifying therapies for patients with higher-risk myelodysplastic syndromes (MDS). However, azacitidine and decitabine are not curative, the median response duration is 11-15 months, and only 10-20 % of patients experience complete hematologic and cytogenetic response. Moreover, once an HMA fails the patient, the prognosis is poor, with a median survival of less than 6 months unless the patient undergoes hematopoietic stem cell transplantation (HSCT).

Low efficacy and high mortality associated with clofarabine treatment of relapsed/refractory acute myeloid leukemia and myelodysplastic syndromes.

Clofarabine, a second-generation nucleoside analog, has clinical activity in relapsed or refractory acute myelogenous leukemia (AML) and higher-risk myelodysplastic syndromes (MDS). However, there are few data evaluating performance of clofarabine in populations of patients not enrolled in clinical trials. We reviewed outcomes for 84 patients treated with clofarabine for relapsed or refractory AML or MDS, either with clofarabine as monotherapy (n=19) or in combination with cytarabine (n=65).

Rasburicase-induced methemoglobinemia in two African-American female patients: an under-recognized and continued problem.

Rasburicase-induced methemoglobinemia is a known adverse effect of patients administered rasburicase for tumor lysis syndrome who have concomitant glucose-6-phosphate dehydrogenase deficiency. This phenomenon has been described in multiple case reports but has been limited to male patients. We present the first case series illustrating this adverse effect in two female patients where morbidity and mortality associated with rasburicase-induced methemoglobinemia were evident.

Inhibition of p38 MAPK suppresses inflammatory cytokine induction by etoposide, 5-fluorouracil, and doxorubicin without affecting tumoricidal activity.

Cancer patients undergoing treatment with systemic cancer chemotherapy drugs often experience debilitating fatigue similar to sickness behavior, a normal response to infection or tissue damage caused by the production of the inflammatory cytokines IL-1beta, TNF-alpha, and IL-6. The p38 mitogen activated protein kinase (p38 MAPK) plays a central role in the production of these cytokines and consequently the development of sickness behavior. Targeted inhibitors of p38 MAPK can reduce systemic inflammatory cytokine production and the development of sickness behavior.
