Pediatric HLT remains uncommon in the United States and criteria for HLT are unclear. The objectives of this study were to review the indications, and outcomes of pediatric HLT.

Data from the Scientific Registry of Transplant Recipients heart and liver databases were used to identify 9245 pediatric isolated heart transplants (PHT), 14134 pediatric isolated liver transplant (PLT), and 20 pediatric HLT (16 patients underwent sHLT [same organ donor] and four patients with a history of PHT followed by PLT [different organ donors]; age ≤21years) between 1992 and 2017. Outcomes included patient survival, and 1-year rates of acute heart and liver rejection.

The median age for pediatric HLT was 15.6 (IQR 10.5, 17.9) years, and included 12males (12/20=60%). In the HLT group, the most common indication for HT was CHD (12/20=60%), and the most common indication for liver transplant was cirrhosis (9/20=45%). The 1, 3, and 5year actuarial survival rates in pediatric simultaneous HLT recipients (n=16) were 93%, 93%, and 93%, respectively, and was similar to isolated PHT alone (88%, 81%, and 75.5%, respectively and isolated PLT alone (84%, 82%, and 80%), respectively. There was no heart or liver rejection reported in the HLT group versus 9.9% in heart and 10.6% in liver transplant-only groups, respectively.

Pediatric HLT is an uncommon but acceptable option for recipients with combined end-organ failure, with intermediate survival outcomes comparable to those of single-organ recipients.

In children with functional dyspepsia (FD), genes involved in pain modulation may be differentially expressed contributing to chronic pain.

Children with suspected FD (cases) and known eosinophilic esophagitis (controls) undergoing esophagogastroduodenoscopy completed the Rome IV Diagnostic, Pain Burden and Frequency Severity-Duration questionnaires. Two antral and two duodenal biopsies were collected and relative fold differences in gene expression for 84 pain-associated genes compared to pain-free controls were calculated.

Sixty-six subjects with FD (postprandial distress syndrome=34, epigastric pain syndrome=7, both=25; 65% female; mean age 13.7years) and 13 pain-free controls (8% female; mean age 12.7) were studied. There were no significant differences in antral and duodenal eosinophilic counts or distribution between the pain and pain-free groups. Pain severity and burden did not differ significantly between FD subgroups and neither measure significantly correlated with eosinophil counts in the antrum or duodenum. Analysis of 47 antral and 39 duodenal biospecimens revealed 5 candidate genes significantly associated with pain burden antral EDN1, PTGES3 and duodenal HTR1A, P2Y1, SCN3A (p<0.01). Subsequent stringent statistical analysis comparing those with significant pain versus no pain revealed antral PTGES3 and duodenal SCN3A were the highest priority candidate genes (p<0.001).

Pain burden in pediatric FD may be linked to antral EDN1, PTGES3 and duodenal HTR1A, P2Y1, SCN3A differential expression. These genes are known to be involved in pain conduction, modulation, and neurotransmission, suggesting potential therapeutic targets for managing pain in FD.

Out-of-hospital cardiac arrests are a leading global cause of mortality. The American Heart Association (AHA) promotes several important strategies associated with improved cardiac arrest (CA) outcomes, including decreasing pulse check time and maintaining a chest compression fraction (CCF)>0.80. Video review is a potential tool to improve skills and analyse deficiencies in various situations; however, its use in improving medical resuscitation remains poorly studied in the emergency department (ED). We implemented a quality improvement initiative, which utilised video review of CA resuscitations in an effort to improve compliance with such AHA quality metrics.

A cardiopulmonary resuscitation video review team of emergency medicine residents were assembled to analyse CA resuscitations in our urban academic ED. Videos were reviewed by two residents, one of whom was a senior resident (Postgraduate Year 3 or 4), and analysed using Spearman's rank correlation coefficient for numerous quality improvement metrics, including pulse check time, CCF, time to intravenous access and time to patient attached to monitor.

We collected data on 94 CA resuscitations between July 2017 and June 2020. Average pulse check time was 13.09 (SD±5.97)seconds, and 38% of pulse checks were <10seconds. After the implementation of the video review process, there was a significant decrease in average pulse check time (P=.01) and a significant increase in CCF (P=.01) throughout the study period.

Our study suggests that the video review and feedback process was significantly associated with improvements in AHA quality metrics for resuscitation in CA amongst patients presented to the ED.

This study aimed to systematically evaluate a classification scheme of secondary peristalsis using functional luminal imaging probe (FLIP) panometry through comparison with primary peristalsis on high-resolution manometry (HRM).

706 adult patients that completed FLIP and HRM for primary esophageal motility evaluation and 35 asymptomatic volunteers ("controls") were included. Secondary peristalsis, that is, contractile responses (CRs), was classified on FLIP panometry by the presence and pattern of contractility as normal (NCR), borderline (BCR), impaired/disordered (IDCR), absent (ACR), or spastic-reactive (SRCR). Primary peristalsis on HRM was assessed according to the Chicago Classification.

All 35 of the controls had antegrade contractions on FLIP panometry with either NCR (89%) or BCR (11%). The average percentages of normal swallows on HRM varied across contractile response patterns from 84% in NCR, 68% in BCR, 39% in IDCR, to 11% in ACR, as did the percentage of failed swallows on HRM 4% in NCR, 12% in BCR, 36% in IDCR, and 79% in ACR. SRCR on FLIP panometry was observed in 18/57 (32%) patients with type III achalasia, 4/15 (27%) with distal esophageal spasm, and 7/15 (47%) with hypercontractile esophagus on HRM.

The FLIP panometry contractile response patterns reflect a pathophysiologic transition from normal to abnormal esophageal peristaltic function with shared features with primary peristaltic function/dysfunction on HRM. Thus, these patterns of the contractile response to distension can facilitate the evaluation of esophageal motility using FLIP panometry.

Nevertheless, their metabolites are far less explored. This pathway plays a crucial role in converting arachidonic acid to hydroxyeicosatetraenoic (HETEs), epoxyeicosatrienoic (EETs), dihydroxyeicosatetraenoic acids (DiHETEs), and dihydroxyeicosatrienoic acids (DiHETrEs), which mediate several physiological and pathological functions. However, CYP450-derived eicosanoids are structurally complex, making those analyses a challenge in lipidomics studies. Herein, a high-resolution multiple-reaction monitoring (MRMHR ) method has been proposed as a powerful tool for the simultaneous analysis of CYP450-eicosanoids on different biological samples. The developed liquid chromatography (LC)-MRMHR method was partially validated according to the Food and Drug Administration (FDA) criteria, demonstrating adequate specificity, linearity, precision, and accuracy. Besides, several biological samples were analyzed to guarantee the feasibility of the method. The proposed strategy may improve the understanding of CYP450-derived eicosanoids in biological systems, which could be fundamental to reveal new aspects of those in physiologic and pathologic conditions.The intracellular pathogen Legionella pneumophila translocates >300 effector proteins into host cells, many of which are regulated at the transcriptional level. Here, we describe a novel L. pneumophila genomic island, which undergoes horizontal gene transfer within the Legionella genus. This island encodes two Icm/Dot effectors LegK3 and a previously uncharacterized effector which we named CegK3, as well as a LuxR type regulator, which we named RegK3. Analysis of this island in different Legionella species revealed a conserved regulatory element located upstream to the effector-encoding genes in the island. Further analyses, including gene expression analysis, mutagenesis of the RegK3 regulatory element, controlled expression studies, and gel-mobility shift assays, all demonstrate that RegK3 directly activates the expression levels of legK3 and cegK3 effector-encoding genes. Additionally, the expression of all the components of the island is silenced by the Fis repressors. Comparison of expression profiles of these three genes among different Legionella species revealed variability in the activation levels mediated by RegK3, which were positively correlated with the Fis-mediated repression. Furthermore, LegK3 and CegK3 effectors moderately inhibit yeast growth, and importantly, they have a strong synergistic inhibitory effect on yeast growth, suggesting these two effectors are not only co-regulated but also might function together.
Past research suggests that patient-provider relationships play a crucial role in patient satisfaction with their medical care. However, the essential relationship elements responsible for this effect have not been elucidated and were examined in this study.

Patients in six gastroenterology clinics at a major medical center completed an anonymous, secure Internet survey about their medical care after a clinic visit. The survey included the validated Satisfaction With Care Scale-37 (SAT-37) and Patient-Physician Relationship Scale (PPRS). ACBI1 Correlations between those scales were calculated, and exploratory factor analysis (EFA) followed by regression analysis was used to create a PPRS Short Form (PPRS-SF) specifically to account for satisfaction with care.

173 patients (114 females and 59males; mean age 49.2years) completed the survey. A range of specific patient-doctor relationship aspects on the PPRS substantially influenced the patients' satisfaction scores. These are grouped into five EFA-derived patieelationship factors that ensure satisfied patients.
