Nectar spur is a hollow extension of certain flower parts and shows strikingly diverse size and shape in Aquilegia. Nectar spur development is involved in cell division and expansion processes. The basic helix-loop-helix (bHLH) transcription factors (TFs) control a diversity of organ morphogenesis, including cell division and cell expansion processes. However, the role of bHLH genes in nectar spur development in Aquilegia is mainly unknown. We conducted a genome-wide identification of the bHLH gene family in Aquilegia to determine structural characteristics and phylogenetic relationships, and to analyze expression profiles of these genes during the development of nectar spur in spurless and spurred species. A total of 120 AqbHLH genes were identified from the Aquilegia coerulea genome. The phylogenetic tree showed that AqbHLH proteins were divided into 15 subfamilies, among which S7 and S8 subfamilies occurred marked expansion. The AqbHLH genes in the same clade had similar motif composition and gene structure the function of AqbHLH genes family in nectar spur development, and has potential implications for speciation and genetic breeding in the genus Aquilegia.
Transcutaneous cardiac pacing (TCP) is a lifesaving procedure for patients with certain types of unstable bradycardia. We aimed to assess the difference in the pacing thresholds between the anteroposterior (AP) and anterolateral (AL) pacer pad positions. The second aim was to characterize the severity of chest wall muscle contractions during TCP.

In this prospective crossover trial, we enrolled patients presenting to the electrophysiology laboratory for elective cardioversion. After successful cardioversion, sedated participants were sequentially paced in both positions. The study procedure concluded after successful capture or inability to achieve capture by 140mA (the pacer's maximum output) in both positions. Pacing thresholds were compared between positions, using a student's paired t-test, assigning a value of 141mA to any trials with non-capture.

Forty-one patients were screened; 20 were enrolled in the study. Seven participants were excluded from the paired analysis (three were prevented from pacing in the second position at the anesthesiologist's discretion, and 4 did not capture in either position). The study population consisted of 14 men and 6 women with a median age of 65years. The mean pacing threshold was 33mA lower (P=0.001, 95% CI 20-45) in the AP (93mA) versus the AL (126mA) position. The median contraction severity score was 3 in the AL position versus 4 in the AP position (P=0.005).

Placing pacer pads in the AP position requires less energy to capture. Major resuscitation guidelines may favor the AP position for TCP.

We compared novel methods of long-term follow-up after resuscitation from cardiac arrest to a query of the National Death Index (NDI). We hypothesized use of the electronic health record (EHR), and internet-based sources would have high sensitivity for identifying decedents identified by the NDI.

We performed a retrospective study including patients treated after cardiac arrest at a single academic center from 2010 to 2018. We evaluated two novel methods to ascertain long-term survival and modified Rankin Scale (mRS) 1) a structured chart review of our health system's EHR; and 2) an internet-based search of a) local newspapers, b) Ancestry.com, c) Facebook, d) Twitter, e) Instagram, and f) Google. If a patient was not reported deceased by any source, we considered them to be alive. We compared results of these novel methods to the NDI to calculate sensitivity. We queried the NDI for 200 in-hospital decedents to evaluate sensitivity against a true criterion standard.

We included 1,097 patients, 897 (82%) alive at discharge and 200 known decedents (18%). NDI identified 197/200 (99%) of known decedents. The EHR and local newspapers had highest sensitivity compared to the NDI (87% and 86% sensitivity, respectively). Online sources identified 10 likely decedents not identified by the NDI. Functional status estimated from EHR, and internet sources at follow up agreed in 38% of alive patients.

Novel methods of outcome assessment are an alternative to NDI for determining patients' vital status. These methods are less reliable for estimating functional status.

An association between post-arrest hyperoxaemia and worse outcomes has been reported for out-of-hospital cardiac arrest (OHCA) patients, but little is known about the relationship between intra-arrest hyperoxaemia and clinically relevant outcomes. This study aimed to investigate the association between intra-arrest hyperoxaemia and outcomes for OHCA patients.

This was an observational study using a registry database of OHCA cases that occurred between 2014 and 2017 in Japan. We included adult, non-traumatic OHCA patients who were in cardiac arrest at the time of hospital arrival and for whom partial pressure of arterial oxygen (PaO
) levels was measured during resuscitation. Main exposure was intra-arrest PaO
level, which was divided into three categories hypoxaemia, PaO
<60mmHg; normoxaemia, 60-300; or hyperoxaemia, ≥300. Primary outcome was favourable functional survival at one month or at hospital discharge. Multivariable logistic regression was performed to adjust for clinically relevant variables.

Among 16,013 patients who met the eligibility criteria, the proportion of favourable functional survival increased as the PaO
categories became higher 0.5% (57/11,484) in hypoxaemia, 1.1% (48/4243) in normoxaemia, and 5.2% (15/286) in hyperoxaemia (p-value for trend<0.001). Higher PaO
categories were associated with favourable functional survival and the adjusted odds ratios increased as the PaO
categories became higher 2.09 (95% CI 1.39-3.14) in normoxaemia and 5.04 (95% CI 2.62-9.70) in hyperoxaemia when compared to hypoxaemia as a reference.

In this observational study of adult OHCA patients, intra-arrest normoxaemia and hyperoxaemia were associated with better functional survival, compared to hypoxaemia.

Significant gaps exist in the pediatric resident (PR) procedural experience. Graduating PRs are not achieving competency in the 13 ACGME recommended procedures. It is unclear why PR are not able to achieve competency, or how existing gaps may be addressed.

We performed in-depth one-on-one semistructured interviews with 12 pediatric residency program directors (PPDs). The interviews were audio-recorded, and transcribed verbatim. Coding of the data using conventional content analysis led to generation of categories, which were validated through consensus development.

We identified 4 main categories, including (1) programs struggle to ensure adequate training in procedural skills for PRs, with various barriers reported; (2) programs develop individualized strategies to address challenges in procedural skills training, and multiple options are necessary; (3) PPDs face challenges defining procedural competency and standardizing expectations; and (4) expectations for PR procedural training may require modification based upon current practice environments. Solutions include simulation, procedural boot camps, and procedural/subspecialty electives.

Numerous methods to combat challenges in PR procedural training have been identified by participating PPDs, including simulation, tailoring electives, and developing institutional guidelines. However, accreditation bodies may need to update procedural expectations based on individual resident career goals and realities of current day practice.

To determine whether a multicomponent intervention focused on early peanut introduction was associated with a lower peanut allergy incidence in young children.

The study cohort comprised all children born January 1, 2013 through December 31, 2018 receiving care at a large health care organization. Intervention activities occurred over 16 months and included provider educational programs, electronic health record tools, and new patient instructions. We used an interrupted time series design to assess whether peanut allergy incidence differed across 3 time periods (preintervention, interim, postintervention) among high- and low-risk children. The primary outcome was incident peanut allergy by age 24 months, defined as peanut allergy in the allergy field or active problem list plus a positive supportive test. Aristolochic acid A Severe eczema and/or egg allergy presence defined high-risk. Because the study was conducted as part of routine care, it was not feasible to measure what counseling clinicians provided, or how and when parents fed their children peanut-containing foods.

In a cohort of 22,571 children, the percent with peanut allergy by age 24 months was 17.3% (116 of 671) among high-risk and 0.8% (181 of 21,900) among low-risk children. In multivariate analyses, the adjusted peanut allergy rate per 100 person-years was not significantly different across study periods among high-risk (9.6 preintervention, 11.7 interim, and 9.9 postintervention, P=.70) or low-risk (0.5 preintervention, 0.7 interim, and 0.5 postintervention, P=.17) children.

In a community-based setting, the incidence of peanut allergy did not decline following a multicomponent intervention focused on early peanut introduction.

Pediatric end of life (EOL) care skills are a high acuity, low occurrence skill set required by pediatric clinicians. Gaps in education and competence for this specialized care can lead to suboptimal patient care and clinician distress when caring for dying patients and their families.

A half-day workshop using a deliberate practice approach was designed by an inter-professional workgroup including bereaved parent consultants. Pediatric fellows (neonatal-perinatal medicine, critical care, hematology oncology, blood and marrow transplant) and advanced practice providers learned and practiced EOL skills in a safe simulation environment with instruction from interprofessional facilitators and standardized patients. Participant perceived competence (self-efficacy) was measured before, immediately-post, and 3 months post workshop.

There were 28 first-time (of 34 total) participants in 4 pilot workshops. Participants reported significantly increased self-efficacy post-workshop for 6 of 9 ratings, which was sustained 3 months afterwards.
