TOP2α/170 is an important target for DNA damage-stabilizing anticancer drugs, whose clinical efficacy is compromised by drug resistance often associated with decreased TOP2α/170 expression. We recently demonstrated that an etoposide-resistant K562 clonal subline, K/VP.5, with reduced levels of TOP2α/170, expresses high levels of a novel C-terminal truncated TOP2α isoform (90 kDa, TOP2α/90). TOP2α/90, the translation product of a TOP2α mRNA that retains a processed intron 19 (I19), heterodimerizes with TOP2α/170 and is a resistance determinant through a dominant-negative effect on drug activity. We hypothesized that genome editing to enhance I19 removal would provide a tractable strategy to circumvent acquired TOP2α-mediated drug resistance. To enhance I19 removal in K/VP.5 cells, CRISPR/Cas9 was used to make channhancing removal of intron 19 and thereby decreasing formation of a truncated TOP2α 90 kDa isoform and increasing expression of full-length TOP2α 170 kDa in these resistant cells. Results demonstrate the importance of RNA processing in acquired drug resistance to TOP2α-targeted drugs.The dramatic increases of opioid use and misuse in the past 15 years have resulted in a focus on the responsible and judicious use of opioids. In this Ethics Rounds, the commentators analyze the case of a 16-year-old girl with lymphoma and opioid misuse whose caregiver may have diverted her opioids. She is now at the end of life and prefers to die at home. The commentators, oncologists, palliative care providers, ethicists, and a medical student agree that supporting the patient's goals and practicing good opioid stewardship are not incompatible. SS-31 They identify additional information that would be required to analyze the case more fully such as the nature of the evidence for misuse and diversion and whether bias inadvertently contributed to these concerns. They agree that multimodal analgesia, including but not limited to opioids, is important. Safeguards could include a contract, directly observed therapy, and/or urine drug screens. Supervision or removal of a caregiver diverting medication or admission of the patient misusing medications would be alternatives if the initial plan was unsuccessful. Such patient-centered care requires well-developed substance misuse treatment, pain management, and home hospice that are adequately reimbursed.
In children, intravenous therapy (IVT) is generally administered via peripheral intravenous catheters (PIVCs) (2-6 cm in length). There is evidence that PIVCs are unreliable after 2 days. Long peripheral catheters (LPCs) (6-15 cm in length) could improve the delivery of IVT. The aim of this trial was to determine if LPCs could decrease catheter failure and the number of catheters in children receiving multiday IVT.

This was an open-label randomized controlled trial conducted at Monash Children's Hospital in Melbourne, Australia. Participants were from the ages of 1 to 17 years, undergoing surgery and requiring >48 hours of postoperative IVT. Participants were randomly assigned to a 2.5-cm 22G PIVC or an 8-cm 22G LPC.

Seventy-two children were randomly assigned, 36 received PIVCs, and 36 received LPCs. The median duration of IVT was 5.1 days and was similar between groups (
= .9). Catheter failure was higher for PIVCs than LPCs (66.7% vs 19.4%; relative risk [RR] 3.4;
= .0001 or 187.9 vs 41.0 failures per 1000 catheter-days). Infiltration was the most common reason for PIVC failure (33.3% vs 2.8%; RR 12.0;
= .001). LPCs exhibited superior life span (4.7 vs 3.5 days [median];
= .01). Children with LPCs were twice as likely to complete therapy with a single catheter (80.6% vs 38.9%; RR 2.1;
= .0006).

LPCs reduce catheter failure and total catheters in children. They should be considered as the first-line device for peripheral access in any child receiving prolonged IVT.

Alzheimer's disease (AD) risk is associated with the TREM2 R47H variant, which impairs ligand binding and consequently microglia responses to Aβ pathology. Here, we show that TREM2 engagement by the mAb hT2AB as surrogate ligand activates microglia in 5XFAD transgenic mice that accumulate Aβ and express either the common TREM2 variant (TREM2 CV) or TREM2 R47H scRNA-seq of microglia from TREM2 CV-5XFAD mice treated once with control hIgG1 exposed four distinct trajectories of microglia activation leading to disease-associated (DAM), interferon-responsive (IFN-R), cycling (Cyc-M), and MHC-II expressing (MHC-II) microglia types. All of these were underrepresented in TREM2 R47H-5XFAD mice, suggesting that TREM2 ligand engagement is required for microglia activation trajectories. Moreover, Cyc-M and IFN-R microglia were more abundant in female than male TREM2 CV-5XFAD mice, likely due to greater Aβ load in female 5XFAD mice. A single systemic injection of hT2AB replenished Cyc-M, IFN-R, and MHC-II pools in TREM2 R47H-5XFAD mice. In TREM2 CV-5XFAD mice, however, hT2AB brought the representation of male Cyc-M and IFN-R microglia closer to that of females, in which these trajectories had already reached maximum capacity. Moreover, hT2AB induced shifts in gene expression patterns in all microglial pools without affecting representation. Repeated treatment with a murinized hT2AB version over 10 d increased chemokines brain content in TREM2 R47H-5XFAD mice, consistent with microglia expansion. Thus, the impact of hT2AB on microglia is shaped by the extent of TREM2 endogenous ligand engagement and basal microglia activation.
