RESUMEN
To evaluate outcomes of patients undergoing heart transplants (HTs) using an intra-aortic balloon pump (IABP) under exception status. Adult patients supported by an IABP who underwent HT between November 18, 2018, and December 31, 2020, as documented in the United Network for Organ Sharing, were included. Patients were stratified according to requests for exception status. Kaplan-Meier methodology was used to look for differences in survival between groups. A total of 1284 patients were included; 492 (38.3%) were transplanted with an IABP under exception status. Exception status patients had higher body mass index, were more likely to be Black, and had longer waitlist times. Exception status patients received organs from younger donors, had a shorter ischemic time, and had a higher frequency of sex mismatch. The 1-year posttransplant survival was 93% for the nonexception and 88% for the exception IABP patients (hazard ratio: 1.85 [95% confidence interval: 1.12-2.86, P = .006]). The most common reason for requesting an exception status was inability to meet blood pressure criteria for extension (37% of patients). The most common reason for an extension request for an exception status was right ventricular dysfunction (24%). IABP patients transplanted under exception status have an increased 1-year mortality rate posttransplant compared with those without exception status.

BACKGROUND/OBJECTIVES: Bronchiolitis is the most common cause of lower respiratory tract infections that lead to hospitalizations in infants and young children. METHODS: In this randomized controlled pilot study, we compared two separate nasal suction devices, namely the over counter device by the brand name of NoseFrida and the standard hospital device NeoSucker, in hospitalized children with bronchiolitis to assess equivalence of length of stay within a ± 5-h equivalence margin and to compare readmission rates and associated complications. Additionally, parental satisfaction for the NoseFrida device was measured with a six question (5-point Likert scale) survey. RESULTS: There were 20 patients randomized to the NeoSucker group and 24 randomized to the NoseFrida group. The mean length of stay for the NoseFrida group was 33.5 ± 25.4 h compared to 31.0 ± 15.6 h in the NeoSucker group, which did not establish equivalence within the ±5-h equivalence margin (p = 0.352). Parents were generally satisfied with the NoseFrida. Patients treated with the two devices had similar frequencies of deep suctioning and readmission within 48 h. CONCLUSIONS: Although the mean length of stay was comparable for bronchiolitis patients treated with the NoseFrida and NeoSucker, the relatively small sample size and large amount of variability precluded demonstrating equivalence. Since this was a pilot, further studies are needed to evaluate the recommendation for the use of such devices in both the hospital setting and in the outpatient management of bronchiolitis.

BACKGROUND: Kidney failure in young people is often unexplained and a significant proportion will have an underlying genetic diagnosis. National Health Service England pioneered a comprehensive genomic testing service for such circumstances accessible to clinicians working outside of genetics. This is the first review of patients using this novel service since October 2021, following its introduction into clinical practice. METHODS: The 'Unexplained Young-Onset End-Stage Renal Disease' (test-code R257) gene panel uses targeted next generation sequencing to analyse 175 genes associated with renal disease in patients under 36 years of age. All tests undertaken between October 2021 and February 2022 were reviewed. Phenotypic data were extracted from request forms and referring clinicians contacted where additional details were required. RESULTS: Seventy-one patients underwent R257 testing over the study period. Among them, 23/71 patients (32%) were confirmed to have a genetic diagnosis and 2/71 (3%) had a genetically suggestive variant. Nephronophthisis and Alport syndrome were the most common conditions identified, (4/23 (17%) with pathogenic variants in NPHP1 and 4/23 (17%) with pathogenic variants in COL4A3/COL4A4). Positive predictors of a genetic diagnosis included a family history of renal disease (60% of positive cases) and extra-renal disease manifestations (48% of positive cases). CONCLUSION: This is the first study to evaluate the R257 gene panel in unexplained young-onset kidney failure, freely accessible to patients meeting testing criteria in England. A genetic diagnosis was identified in 32% of patients. This study highlights the essential and expanding role that genomic testing has for children and families affected by renal disease today.
