The field of pediatric cardiology has witnessed major changes over the past few decades that have considerably altered patient outcomes, including decreasing mortality rates for many previously untreatable conditions. Despite this, some pediatric cardiology programs are increasingly choosing to partner with their institutional palliative care teams. Why is this? The field of palliative care also has experienced significant shifts over a similar period of time. Today's palliative care is focused on improving quality of life for any patient with a serious or life-threatening condition, regardless of where they might be on their disease trajectory. Research has clearly demonstrated that improved outcomes can be achieved for a variety of patient cohorts through early integration of palliative care; recent evidence suggests that the same may be true in pediatric cardiology. All pediatric cardiologists need to be aware of what pediatric palliative care has to offer their patients, especially those who are not actively dying. This manuscript reviews the evolution of palliative care and provides a rationale for its integration into the care of children with advanced heart disease. Readers will gain a sense of how and when to introduce palliative care to their families, as well as insight into what pediatric palliative care teams have to offer. Additional research is required to better delineate optimal partnerships between palliative care and pediatric cardiology so that we may promote maximal quality of life for patients concurrently with continued efforts to push the boundaries of quantity of life.Erdheim-Chester disease (ECD), a rare non-Langerhans cell histiocytosis, involves multiple systems and may display pericardial effusion. Herein, we report a 60-year-old man who presented with refractory pericardial effusion of "unknown" etiology. As in this patient, ECD should be considered when rapidly recurrent pericardial effusion is accompanied by a pseudotumoral lesion of the right atrium and other systemic manifestations.Sickle cell disease (SCD) is caused by a single point mutation in the β-chain of the hemoglobin gene that results in the replacement of glutamic acid with valine in the hemoglobin protein. However, recent studies have demonstrated that alterations in several other genes, especially immune related genes, may be associated with complications of SCD. In fact, higher chronic inflammatory status is related to more severe clinical symptoms in SCD patients, suggesting crucial roles of the immune system in SCD physiopathology. Nevertheless, although participation of innate immune cells in SCD pathogenesis has been broadly and extensively described, little is known about the roles of the adaptive immune system in this disease. selleck compound In addition, the influence of treatments on the immune system of SCD patients and their complications (such as alloimmunization) are not yet completely understood. Thus, we reviewed the current knowledge about the immune mechanisms involved in SCD pathogenesis. We suggest recommendations for future studies to allow for a broader understanding of SCD pathogenesis, helping in the development of new therapies and improvement in the life quality and expectancy of patients.Trypanosoma brucei is an important human pathogen. In this study, we have focused on the characterization of FtsH protease, ATP-dependent membrane-bound mitochondrial enzyme important for regulation of protein abundance. We have determined localization and orientation of all six putative T.brucei FtsH homologs in the inner mitochondrial membrane by in silico analyses, by immunofluorescence, and with protease assay. The evolutionary origin of these homologs has been tested by comparative phylogenetic analysis. Surprisingly, some kinetoplastid FtsH proteins display inverted orientation in the mitochondrial membrane compared to related proteins of other examined eukaryotes. Moreover, our data strongly suggest that during evolution the orientation of FtsH protease in T. brucei varied due to both loss and acquisition of the transmembrane domain.Bladder cancer is the tenth most common cancer worldwide and has been associated with high mortality and morbidity. Although the treatment of bladder cancer is based on well-defined tumor classifications and gradings, patients still experience different clinical response. The heterogeneity of this disease calls for substantial research with more in-depth molecular characterization, with the hope of identifying new diagnostic and treatment options. In recent years, non-coding RNAs (ncRNAs), particularly, microRNAs (miRNAs), long non-coding RNA (lncRNAs), and circular RNAs (circRNAs) were found to be associated with bladder cancer occurrence and development. This review highlights the recent findings concerning ncRNAs and their relevance to the pathogenesis of bladder cancer. This may provide a foundation for developing highly specific diagnostic tools and more robust therapeutic strategies in the future.Trait worry refers to a tendency toward increased vigilance to threat and reduced tolerance of uncertainty. While it has been established as a risk factor of general morbidity, knowledge about autonomic regulation in trait worry remains scarce. This study investigated parasympathetic cardiac control in trait worry, in the context of attentional focus. Healthy groups with high and low worry were selected using the Penn State Worry Questionnaire (n = 40 per group). Heart rate variability (HRV) was recorded in the high frequency (HF) and low frequency (LF) bands while participants performed a breathing focus task. The task included a phase of instructed worry and two phases during which participants´ ability to concentrate on their breathing was assessed. As compared to the low worry group, the high worry group exhibited lower HRV in the LF band during both breathing focus phases and smaller reduction of LF HRV during instructed worry. HF HRV did not differ between groups. High worry was associated with impaired ability to concentrate on breathing and more intrusive thoughts. In the total sample, negative intrusions correlated negatively with LF HRV during the first breathing focus phase and LF HRV reactivity. Instructed worry led to greater perceived stress and deterioration of mood in high worry participants. Reduced LF HRV reflects blunted parasympathetic cardiac control in trait worry, associated with elevated risk of poor health outcomes. In addition, it might represent a psychophysiological correlate of reduced cognitive inhibition, which interferes with attentional focus and impedes control of threat processing and perseverative thinking.
