Gray matter associations with extinction-induced neural activation in patients with anxiety disorders.

The relationship between structural characteristics and extinction-induced brain activations in anxiety disorders (ANX) remains a space for greater exploration. In this study, we assessed gray matter volume (GMV) and its associated functional activations during fear extinction memory recall in an ANX cohort. We performed voxel-based morphometry analysis to examine GMVs from ANX (n = 92) and controls (n = 73). We further examined the correlation between GMVs and extinction-induced neural activations during recall across groups. In the patients' group, we observed decreased GMV in the anterior hippocampus and increased GMV in the dorsolateral prefrontal cortex (dlPFC). Hippocampal volume was positively correlated with ventromedial prefrontal cortex activation in healthy controls, while it was negatively correlated with dorsal anterior cingulate cortex (dACC) activation in ANX. The dlPFC volume was positively correlated with activations of dACC, pre- and post-central gyrus, and supramarginal gyrus only in healthy controls. Therefore, the link between structural and functional imbalance within the hippocampus and dlPFC might contribute to the pathophysiology of ANX. In the controls, the relationship between structural variance in the hippocampus and dlPFC and extinction-induced neural activations is consistent with a greater ability to regulate fear responding; associations that were absent in the ANX cohort. Furthermore, our findings of structure-function abnormalities within key nodes of emotional homeostasis in ANX point to dlPFC as a potential neural node to target using neuromodulation tools.

Multi-Level Regulatory Interactions between NF-κB and the Pluripotency Factor Lin28.

An appreciation for the complex interactions between the NF-κB transcription factor and the Lin28 RNA binding protein/let-7 microRNA pathways has grown substantially over the past decade. Both the NF-κB and Lin28/let-7 pathways are master regulators impacting cell survival, growth and proliferation, and an understanding of how interfaces between these pathways participate in governing pluripotency, progenitor differentiation, and neuroplastic responses remains an emerging area of research. In this review, we provide a concise summary of the respective pathways and focus on the function of signaling interactions at both the transcriptional and post-transcriptional levels. Regulatory loops capable of providing both reinforcing and extinguishing feedback have been described. We highlight convergent findings in disparate biological systems and indicate future directions for investigation.

The impact of pharmacist telephone calls after discharge on satisfaction of oncology patients: A randomized controlled study.

Purpose The aim of the study was to determine the impact of telephone follow-up calls on satisfaction in oncology patients after hospital discharge. Method A randomized controlled study, in which patients were randomized into two groups: The experimental group with the telephone follow-up (TFU) calls (intervention) and the control group (no intervention). The telephone follow-up call was conducted within 72 h after discharge. During the call, patients were asked about their medications, namely, whether they received them, understood how to take them, and whether they developed any medication-related adverse effect. Both groups were contacted by phone two weeks later to assess their satisfaction with the discharge medication instructions and the provided pharmaceutical services, using the 5-point Likert scale. In addition, hospital records were reviewed for emergency room visits and hospital readmissions within 30 days after discharge. Results There was no difference in the percentage of patients who reported being very satisfied between both the intervention and the control groups (45% intervention vs. 48% control, P = 0.68). The mean time of the intervention phone call was 3 ± 1.7 (SD) min. During the telephone follow-up call, medication-related problems were identified in 20% of the patients. There was no significant difference in emergency room visits and hospital readmissions in the intervention group vs. control (44% vs. 53%, P = 0.123) and (37% vs. 43%, P = 0.317), respectively. Conclusion Telephone follow-up calls conducted by a pharmacist to discharged oncology patients did not improve patients' satisfaction, emergency room visits or hospital readmissions; however, they helped to identify medication-related adverse effects in the oncology patients.
