ABSTRACT
Chronic spontaneous urticaria (CSU) is perceived as a difficult to manage disease with negative impact on quality of life. The aim of this study was to highlight how to improve the care of people with CSU, using the methodology of narrative medicine. From June 2014 to March 2015, CSU-diagnosed patients and their physicians were asked to record their experiences of the condition in writing. Fourteen healthcare teams participated: 41% considered CSU as a challenge to overcome, while 22% experienced CSU as a big commitment. The number of professional involved was evaluated as insufficient in 11 hospitals. Seventy-five percent of the 190 Italian patients had visited 3 or more physicians before receiving a final diagnosis, with a perceived waste of time and resources. The therapeutic pathways were described as unsatisfactory in 83% of cases. As a result, anger and frustration were life-dominant emotions in 92% of patients. The critical points of the care pathway are related to organizational issues and lack of awareness.

AIMS: Growth hormone deficiency therapy is demanding for patients and caregivers. Teams engaged in the clinical management of growth hormone deficiency therapy need to know how families live with this condition, to provide an adequate support and prevent the risk of withdrawal from therapy. METHODS: Using Narrative Medicine, testimonies from patients, their parents and providers of care were collected from 11 Italian centers. Narrations were analyzed throughout an elaboration of recurring words and expressions. RESULTS: Although care management and outcomes were considered satisfying in the 182 collected narratives, recurring signals of intolerance among adolescents and the worry of not being well informed about side effects among parents are open issues. CONCLUSION: Narratives found that communication issues could decrease adherence and influence the physicians' clinical practice.
ABSTRACT
A key regulatory gene in definitive erythropoiesis is the erythroid Kruppel-like factor (Eklf or Klf1). Klf1 knockout (KO) mice die in utero due to severe anemia, while residual circulating red blood cells retain their nuclei. Dnase2a is another critical gene in definitive erythropoiesis. Dnase2a KO mice are also affected by severe anemia and die in utero. DNase II-alpha is expressed in the central macrophage of erythroblastic islands (CMEIs) of murine fetal liver. Its main role is to digest the DNA of the extruded nuclei of red blood cells during maturation. Circulating erythrocytes retain their nuclei in Dnase2a KO mice. Here, we show that Klf1 is expressed in CMEIs and that it binds and activates the promoter of Dnase2a. We further show that Dnase2a is severely downregulated in the Klf1 KO fetal liver. We propose that this downregulation of Dnase2a in the CMEI contributes to the Klf1 KO phenotype by a non-cell-autonomous mechanism.

The transcription of the DeltaN133p53 isoform of the TP53 gene is controlled by an internal promoter region (IPR) containing eight polymorphisms in 11 common haplotypes, following a resequencing of 47 Caucasians. We assayed the functional effects of the commonest six haplotypes on the promoter activity with a luciferase reporter system, in HeLa and 293T cells. These studies showed that different IPR haplotypes are associated with differences in the promoter activity resulting in marked variation in the baseline expression of DeltaN133p53. In vivo quantitative-polymerase chain reaction (PCR) on human tissues confirmed that the baseline levels of DeltaN133p53 showed haplotype specific differences that paralleled those seen in vitro. When cell lines were treated with camptothecin, the fold-increase in DeltaN133p53 levels was dose-dependent but haplotype-independent (i.e., similar for all the haplotypes). Finally, we used an electrophoretic mobility shift assay to analyze the rs1794287 polymorphism and found changes in the pattern of protein binding. This partially confirmed our in silico analysis showing that the polymorphism rs1794287 can affect the function of the internal promoter by changing its affinity for several transcription factors. Thus, we showed that the expression of DeltaN133p53 is under genetic control, and suggested the presence of interindividual differences underlying this mechanism.
