Supraventricular tachycardia (SVT) is the most common arrhythmia in the pediatric population. Adenosine is widely accepted as the first-line pharmacological treatment for hemodynamically stable SVT, constituting a class I recommendation in the 2020 American Heart Association guidelines for pediatric life support (2020 American Heart Association Guidelines for cardiopulmonary resuscitation and emergency cardiovascular care). As most pediatric SVTs are dependent on the atrioventricular node (AVN) for their propagation, and adenosine acts primarily on the AVN, adenosine will frequently terminate the arrhythmia. The term "adenosine failure" is often used to describe when its administration does not result in sustained termination of the tachycardia. Because of its very short half-life, there is confusion between improper delivery, failure to have any effect on the tachycardia, or transient termination. There are some pediatric SVTs, which are not AVN dependent, and which truly are refractory to adenosine. Simulmproper delivery, failure to have any effect on the tachycardia, or transient termination. There are some pediatric SVTs, which are not AVN dependent, and which truly are refractory to adenosine. Simultaneous electrocardiogram recording during administration can provide important information to differentiate between adenosine resistance and transient adenosine effect, thus guiding further management.
The main purpose of this study was to investigate the prevalence, characteristics, and intensity of children's pain in emergency departments. The secondary purpose was to evaluate the interobserver agreement regarding the level of pain perceived by professionals, parents, and children.

This was a multicenter, survey-based research study on 0- to 18-year-old patients visiting 1 of the 15 hospitals that form part of the Working Group on Analgesia and Sedation of the Spanish Society of Pediatric Emergency Medicine between October and December 2018. The surveys recorded pain presence, intensity, characteristics, and location.

The study included 1216 surveys. At the time of the interview, 646 patients were experiencing pain, a prevalence of 53.1% (95% confidence interval, 50.3%-55.9%), with 25.38% reporting mild, 36.68% moderate, and 37.46% intense pain. Among the patients, 29.9% had abdominal pain and 14.1% pain in their legs.The pain lasted less than 24 hours in 48.2% of the patients, whereas only 3.0% experienced pain during more than 15 days. The parents of 50.7% of the children had provided an analgesic at home.Interrater agreement regarding pain levels was k = 0.35 between professionals and children, k = 0.38 between children and parents, and k = 0.17 between parents and professionals. For children unable to cooperate, the agreement between professional/child and the parents was k = 0.11.

Pain is a common symptom among emergency department patients, and its evaluation should therefore be obligatory. We found low interrater agreement on pain levels between patients, professionals, and parents, which confirms how difficult it is to accurately evaluate pain intensity.

Unintentional injury is the leading cause of death in children older than 1 year and disproportionately affects pediatric patients in low- and middle-income countries.Improved prehospital care capacity has demonstrated the ability to improve care and save lives. Our collaboration developed and implemented a sustainable prehospital emergency pediatrics care course (EPCC) for Service d'Aide Medicale Urgente, the public emergency medical service in Rwanda.

A 1-day context-specific EPCC was developed based on international best practices and local feedback. Two cohorts were created to participate in the course. The first group, EPCC 1, was made of 22 Service d'Aide Medicale Urgente providers with preexisting knowledge on the topic who participated in the course and received training to lead future sessions. After completion of the EPCC1, this group led the second cohort, EPCC 2, which was composed of 26 healthcare providers from around Rwanda. Each group completed a 50 question assessment before and after the of a context-appropriate prehospital pediatric training program in Kigali, Rwanda. This program may be effective to support capacity development for prehospital care in Rwanda using a qualified local source of instructors.
Male adolescents frequently present to the emergency department (ED) and many participate in behaviors increasing their risk of sexually transmitted infections and unintended pregnancies. Although the ED visit may represent an intervention opportunity, how best to design and deliver a sexual health intervention matching the preferences of adolescent male users is unclear. Our objective was to explore receptivity to and preferences for sexual health interventions among adolescent male ED patients.

In this qualitative study, we asked sexually active male ED patients aged 14 to 21 years about their attitudes toward ED-based sexual health interventions and preferences for intervention modalities. Participants interacted with an early prototype of a digital intervention to gather specific feedback. Enrollment continued until saturation of key themes. Interviews were recorded, transcribed, and coded based on thematic analysis using NVivo.

Participants (n = 42) were predominantly 18 to 21 years (63%) and Hispanic (79%). Although most (71%) had sex in the prior 3 months, 45% did not use a condom at last intercourse and 17% had impregnated a partner. Participants viewed the ED visit as unused time without distracting influences, suitable for educational sexual health interventions. They considered ED-based digital interventions a reliable and confidential source of information. Engaging interventions allowed user control and provided novel and relatable content.

Adolescent male ED patients are receptive to ED-based digital sexual health interventions. click here These identified preferences should be considered when designing future user-informed sexual health interventions for the ED setting.

The aim of this study was to evaluate the venous-to-arterial carbon dioxide tension difference during early resuscitation in pediatric septic shock.

A prospective observational study was conducted in the pediatric intensive care unit of a tertiary care teaching. Children having septic shock aged from 3 to 60 months were studied within the first 24 hours of admission. Central venous and peripheral arterial blood samples for blood gases analysis at time of central venous catheter insertion and after 6 hours were obtained. Central venous carbon dioxide pressure, arterial carbon dioxide pressure, and their difference (delta Pco2) were recorded. Patients were categorized, accordingly to delta Pco2 after 6 hours of resuscitation, into high delta Pco2 group (≥6 mm Hg) and low delta Pco2 group (<6 mm Hg).

Oxygen extraction ratio at 6 hours of resuscitation was significantly lower among the low delta Pco2 group. Arterial lactate showed marked improvement in the low delta Pco2 group to be less than 2 mmol/L at 12 hours of resuscitation. Low delta Pco2 group showed significant higher shock reversal with shorter shock reversal time. Mortality was significantly lower among low delta Pco2 group with shorter pediatric intensive care unit stay.

Delta Pco2 after 6 hours of resuscitation of <6 mm Hg indicates normalization of tissue perfusion during pediatric septic shock management. It could be used as a complementary tool to guide the resuscitation in the early phase of pediatric septic shock.

To identify changes in opioid prescribing across a diverse array of medical specialties after the release of the 2016 CDC Guideline for Prescribing Opioids for Chronic Pain.

Interrupted time-series analysis of data from a commercial prescribing database.

De-identified recipients of opioid prescriptions dispensed at U.S. retail pharmacies between 2015 and 2019.

Opioid dispensing data were obtained from the IQVIA Longitudinal Prescription (LRx) database, representing more than 800 million opioid prescriptions. Monthly dispensing rates, dosage in morphine milligram equivalents (MME), and mean prescription duration were calculated across 29 medical specialties. Changes in dispensing after the release of the 2016 CDC Guideline were assessed through interrupted time-series analysis.

Declining trends in opioid dispensing accelerated in 24 of 29 specialty groups after the release of the CDC Guideline (P &lt; 0.05 for 15 groups). Decreases were greatest among family medicine clinicians, where declines acmary care could have interest in evaluating opioid prescribing practices, supporting the importance of specialty-specific guidance that balances the individualized risks and benefits of opioids and the role of non-opioid treatments.
The sequencing of the wheat (Triticum aestivum) genome has been a methodological challenge for many years owing to its large size (15.5 Gb), repeat content, and hexaploidy. Many initiatives aiming at obtaining a reference genome of cultivar Chinese Spring have been launched in the past years and it was achieved in 2018 as the result of a huge effort to combine short-read sequencing with many other resources. Reference-quality genome assemblies were then produced for other accessions, but the rapid evolution of sequencing technologies offers opportunities to reach high-quality standards at lower cost.

Here, we report on an optimized procedure based on long reads produced on the Oxford Nanopore Technology PromethION device to assemble the genome of the French bread wheat cultivar Renan.

We provide the most contiguous chromosome-scale assembly of a bread wheat genome to date. Coupled with an annotation based on RNA-sequencing data, this resource will be valuable for the crop community and will facilitate the rapid selection of agronomically important traits. We also provide a framework to generate high-quality assemblies of complex genomes using ONT.

Traditional biomonitoring approaches have delivered a basic understanding of biodiversity, but they cannot support the large-scale assessments required to manage and protect entire ecosystems. This study used DNA metabarcoding to assess spatial and temporal variation in species richness and diversity in arthropod communities from 52 protected areas spanning 3 Canadian ecoregions.

This study revealed the presence of 26,263 arthropod species in the 3 ecoregions and indicated that at least another 3,000-5,000 await detection. Results further demonstrate that communities are more similar within than between ecoregions, even after controlling for geographical distance. Overall α-diversity declined from east to west, reflecting a gradient in habitat disturbance. Shifts in species composition were high at every site, with turnover greater than nestedness, suggesting the presence of many transient species.

Differences in species composition among their arthropod communities confirm that ecoregions are a useful synoptic for biogeographic patterns and for structuring conservation efforts.
