Integrating genetic subtypes with PET scan monitoring to predict outcome in diffuse large B-cell lymphoma.

Next Generation Sequencing-based subtyping and interim- and end of treatment positron emission tomography (i/eot-PET) monitoring have high potential for upfront and on-treatment risk assessment of diffuse large B-cell lymphoma patients. We performed Dana Farber Cancer Institute (DFCI) and LymphGen genetic subtyping for the HOVON84 (n = 208, EudraCT-2006-005174-42) and PETAL (n = 204, EudraCT-2006-001641-33) trials retrospectively combined with DFCI genetic data (n = 304). For all R-CHOP treated patients (n = 592), C5/MCD- and C2/A53-subtypes show significantly worse outcome independent of the international prognostic index.

Attractive targeted sugar baits for malaria control in western Kenya (ATSB-Kenya): enrolment characteristics of cohort children and households.

Background: In western Kenya, a cluster-randomized trial is assessing the impact of attractive targeted sugar baits (ATSBs) on malaria in children enrolled in three consecutive cohorts. Here, characteristics of children and households at enrolment, and factors associated with baseline malaria prevalence are described.

Methods: Children aged 1 to < 15 years were randomly selected by cluster (n = 70) from a census database.

Comparison of HiDAC Versus FLAG-IDA in the Treatment of Relapsed Acute Myeloid Leukemia and High-Risk Myelodysplastic Syndrome.

Background: Relapsed acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (HR-MDS) are associated with a poor prognosis. It is unknown which re-induction therapy provides the highest chance of durable remission. Commonly used therapies are high dose cytarabine (HiDAC) and triple therapy consisting of fludarabine, cytarabine, and idarubicin combined with granulocyte colony-stimulating factor (FLAG-IDA).

Immunohistochemical Staining Properties of Osteopontin and Ki-67 in Feline Meningiomas.

The high recurrence rate of feline meningioma despite the generally benign histomorphology warrants additional markers of clinical aggressiveness. The Ki-67 index is commonly used as prognostic marker for meningioma recurrence in people. Osteopontin (OPN) is a protein involved in tumor progression and may be a potential malignancy marker.

Precision genome editing using combinatorial viral vector delivery of CRISPR-Cas9 nucleases and donor DNA constructs.

Genome editing based on programmable nucleases and donor DNA constructs permits introducing specific base-pair changes and complete transgenes or live-cell reporter tags at predefined chromosomal positions. A crucial requirement for such versatile genome editing approaches is, however, the need to co-deliver in an effective, coordinated and non-cytotoxic manner all the required components into target cells. Here, adenoviral (AdV) and adeno-associated viral (AAV) vectors are investigated as delivery agents for, respectively, engineered CRISPR-Cas9 nucleases and donor DNA constructs prone to homologous recombination (HR) or homology-mediated end joining (HMEJ) processes.
