Gene set variation analysis (GSVA) revealed differences in several oncogenic pathways among risk groups, including upregulation of gene sets related to oncogenic KRAS signaling for the high-risk group. Finally, in silico drug screen analysis revealed numerous compounds targeting EGFR signaling with significantly lower efficacy for cancer cell lines with a higher risk phenotype, but also indicated potential vulnerabilities. IMPLICATIONS The established risk model identifies patients with primary HNSCC, but also other cancers at a higher risk for treatment failure, who might benefit from a therapy targeting SOX2/SOX9-related gene regulatory and signaling networks.Since its outbreak in December 2019, the novel coronavirus 2019 (COVID-19) has spread to 191 countries and caused millions of deaths. Many countries have experienced multiple epidemic waves and faced containment pressures from both domestic and international transmission. In this study, we conduct a multiscale geographic analysis of the spread of COVID-19 in a policy-influenced dynamic network to quantify COVID-19 importation risk under different policy scenarios using evidence from China. Our spatial dynamic panel data (SDPD) model explicitly distinguishes the effects of travel flows from the effects of transmissibility within cities, across cities, and across national borders. We find that within-city transmission was the dominant transmission mechanism in China at the beginning of the outbreak and that all domestic transmission mechanisms were muted or significantly weakened before importation posed a threat. We identify effective containment policies by matching the change points of domestic and importation transmissibility parameters to the timing of various interventions. Our simulations suggest that importation risk is limited when domestic transmission is under control, but that cumulative cases would have been almost 13 times higher if domestic transmissibility had resurged to its precontainment level after importation and 32 times higher if domestic transmissibility had remained at its precontainment level since the outbreak. Our findings provide practical insights into infectious disease containment and call for collaborative and coordinated global suppression efforts.

To longitudinally examine the nature of moral distress (MoD) experienced by clinicians caring for extremely low gestational age neonates.

Neonatologists, medical trainees, and nurses were surveyed at regular intervals on their experience of MoD and their preferred level of care in relation to 99 neonates born <28 weeks' gestational age managed from birth until discharge or death in 2 tertiary NICUs. Clinicians reporting significant distress (≥6 of 10 on Wocial's Moral Distress Thermometer) were asked to provide open-ended responses on why they experienced MoD. Descriptive statistics were used to analyze frequency and intensity of MoD across different clinician characteristics. Open-ended responses were analyzed by using mixed methods.

Over 18 months, 4593 of 5332 surveys (86% response rate) were collected. MoD was reported on 687 (15%) survey occasions; 91% of neonates elicited MoD during their hospitalization. In their open-ended answers, clinicians invoked 5 main themes to explain their distress (1) infant-centered reasons (83%), including illness severity, predicted outcomes, and disproportionate care; (2) management plans (26%); (3) family-centered reasons (19%); (4) parental decision-making (16%); and (5) provider-centered reasons (15%). MoD was strongly associated with the perception of "parents wanting too much." Neonatologists experienced less distress and were more likely than nurses and trainees to align preferred levels of care with family wishes.

The majority of preterm infants will generate some MoD; however, it is rarely shared and of a sustained nature. The main constraint reported by clinicians was "parents wanting too much," leading to disproportionate care.

After the US coronavirus disease 2019 outbreak, overall prescription dispensing declined but then rebounded. Whether these same trends occurred for children is unknown.

Using the IQVIA National Prescription Audit, which contains monthly dispensing counts from 92% of US retail pharmacies, we assessed changes in the monthly number of prescriptions dispensed to US children aged 0 to 19 years during 2018-2020. We compared dispensing totals in April to December 2020 and April to December 2019 overall, by drug class, and among drug classes that typically treat acute infections (eg, antibiotics) or chronic diseases (eg, antidepressants).

Between January 2018 and February 2020, the median monthly number of prescriptions dispensed to children was 25 744 758. Dispensing totals declined from 25 684 219 to 16 742 568 between March and April 2020, increased to 19 657 289 during October 2020, and decreased to 15 821 914 during December 2020. Dispensing totals during April to December 2020 (160 630 406) were 27.1% lowted drugs than for chronic disease drugs. Decreased dispensing of the latter is potentially concerning and warrants further investigation. Pinometostat concentration Whether reductions in dispensing of infection-related drugs are temporary or sustained will be important to monitor going forward.Dysfunction in T cells limits the efficacy of cancer immunotherapy. We profiled the epigenome, transcriptome, and enhancer connectome of exhaustion-prone GD2-targeting HA-28z chimeric antigen receptor (CAR) T cells and control CD19-targeting CAR T cells, which present less exhaustion-inducing tonic signaling, at multiple points during their ex vivo expansion. We found widespread, dynamic changes in chromatin accessibility and three-dimensional (3D) chromosome conformation preceding changes in gene expression, notably at loci proximal to exhaustion-associated genes such as PDCD1, CTLA4, and HAVCR2, and increased DNA motif access for AP-1 family transcription factors, which are known to promote exhaustion. Although T cell exhaustion has been studied in detail in mice, we find that the regulatory networks of T cell exhaustion differ between species and involve distinct loci of accessible chromatin and cis-regulated target genes in human CAR T cell exhaustion. Deletion of exhaustion-specific candidate enhancers of PDCD1 suppress the expression of PD-1 in an in vitro model of T cell dysfunction and in HA-28z CAR T cells, suggesting enhancer editing as a path forward in improving cancer immunotherapy.
