Paragangliomas Arising From the Laryngeal Paraganglia: Thyroid and Laryngeal Paragangliomas With Radiology-Pathology Correlation.

Paragangliomas are neuroendocrine tumors that arise from the embryonic neural crest cells of the extra-adrenal chromaffin and non-chromaffin cellular system. Paragangliomas arising from the laryngeal paraganglia, which occur in the thyroid and larynx, are a rare subset of paragangliomas compared to the more common locations of the carotid body, vagale, jugular, and tympanic paragangliomas. The preoperative diagnosis of both thyroid and laryngeal paragangliomas may pose a challenge due to cytological, pathological, and imaging non-specificity that overlaps with many other neoplasms.

Clinical Correlates of Cerebellar Injury in Preterm Infants with Surgical Necrotizing Enterocolitis.

Objective: Determine the risk factors of cerebellar injury in infants with surgical necrotizing enterocolitis (NEC).

Methods: Retrospective study compared clinical/pathological information between surgical NEC infants with and those without cerebellar injury.

Results: Infants with cerebellar injury (21/65, 32.

A target enrichment probe set for resolving phylogenetic relationships in the coffee family, Rubiaceae.

Premise: Rubiaceae is among the most species-rich plant families, as well as one of the most morphologically and geographically diverse. Currently available phylogenies have mostly relied on few genomic and plastid loci, as opposed to large-scale genomic data. Target enrichment provides the ability to generate sequence data for hundreds to thousands of phylogenetically informative, single-copy loci, which often leads to improved phylogenetic resolution at both shallow and deep taxonomic scales; however, a publicly accessible Rubiaceae-specific probe set that allows for comparable phylogenetic inference across clades is lacking.

Postoperative Outcomes, and Growth and Brain Injury Outcomes in Spontaneous Intestinal Perforation vs Surgical Necrotizing Enterocolitis in Preterm Infants.

Objective: To compare the clinical outcomes in preterm infants following surgical necrotizing enterocolitis (sNEC) and spontaneous intestinal perforation (SIP).

Methods: Retro-spective comparison of clinical information in preterm infants with sNEC and SIP admitted between January, 2013 and December 31, 2018. The clinical outcomes were compared in two groups, including postoperative and brain injury detected on brain magnetic resonance imaging (MRI) after clinical and histopathological confirmation of the SIP and the NEC diagnosis.

Outcomes by disease onset, sex, and intervention in neonates with SIP and surgical NEC.

Background: Outcomes of infants following surgical necrotizing enterocolitis (NEC) and spontaneous intestinal perforation (SIP) categorized by the age of onset, interventions, and sex are not well defined.

Methods: Retrospective comparison of infants categorized by age of onset (NEC at <10, 10-20, and >20 days) and SIP at <7 versus ≥7 days), sex, and intervention [Penrose Drain (PD) vs. laparotomy].

Imaging and Demographic Risk Factors in the Diagnosis of Pediatric Nonaccidental Trauma.

Background: The patient described in this case received a diagnosis of severe head trauma that resulted in death. Imaging findings, along with discrepancies in the parental explanation of the incident, aided the forensic investigators to identify the case as nonaccidental trauma (NAT).

Discussion: Identifying demographic risk factors and performing proper clinical evaluations can serve an important role in the diagnosis of pediatric NAT.

A New Transgenic Tool to Study the Ret Signaling Pathway in the Enteric Nervous System.

The receptor tyrosine kinase Ret plays a critical role in regulating enteric nervous system (ENS) development. Ret is important for proliferation, migration, and survival of enteric progenitor cells (EPCs). Ret also promotes neuronal fate, but its role during neuronal differentiation and in the adult ENS is less well understood.

A deceptive mass on neonatal ultrasound and a fetal brain MRI-confirmed complex dural arteriovenous fistula postnatally: illustrative case.

Background: Dural arteriovenous fistulas (dAVFs) are direct, aberrant connections between dural arteries and cerebral veins. In neonates, delayed diagnosis results in grim outcomes. Treatment involves endovascular management because of its success and tolerability.

A case of head and neck cutaneous squamous cell carcinoma highlighting aggressive perineural features.

Cutaneous squamous cell carcinoma (cSCC) is the second most common nonmelanoma skin cancer in the United States following basal cell carcinoma. The majority are successfully cured by surgical excision or Mohs microsurgery. A subset of cSCCs are more aggressive and likely to recur locally, spread to regional lymph nodes or even distantly, and can even result in death.

Dopamine activates astrocytes in prefrontal cortex via α1-adrenergic receptors.

The prefrontal cortex (PFC) is a hub for cognitive control, and dopamine profoundly influences its functions. In other brain regions, astrocytes sense diverse neurotransmitters and neuromodulators and, in turn, orchestrate regulation of neuroactive substances. However, basic physiology of PFC astrocytes, including which neuromodulatory signals they respond to and how they contribute to PFC function, is unclear.

Clinical impact of severe acute kidney injury on post-operative and brain injury outcomes in preterm infants following surgical necrotizing enterocolitis.

Background: To evaluate post-operative outcomes and white matter injury (WMI) using brain MRI at term equivalent in neonates with and without severe acute kidney injury (AKI) following surgical necrotizing enterocolitis (NEC).

Methods: A retrospective cohort study comparing neonates with severe (Stage 2/3) other (no AKI/Stage 1) AKI using KDIGO classification with multivariable models assessing this association in the context of multiple systemic comorbidities.

Results: Of 103 neonates with surgical NEC, 60 (58%) had severe AKI.

Physical activity, burnout and quality of life in medical students: A systematic review.

Background: Medical students are at risk of burnout and reduced quality of life (QoL). The risk of burnout doubles from third to sixth year of medical school, and medical students have an 8%-11% lower QoL than nonmedical students. It is imperative to prevent this, as burnout and reduced QoL is independently associated with errors in practice.

Peer reflective groups: Creating a nurturing and safe community for aspiring clinical psychologists to build their collective voice.

Assistant Psychologist (AP) and Honorary Assistant Psychologist (HAP) roles provide an opportunity to gain the experience needed to progress onto the Clinical Psychology doctorate, making them very competitive to obtain. Nationally, there have been reports that people fulfilling these roles can face a number of challenges including poorly defined job descriptions, difficulty developing a voice within hierarchical organisation structures and balancing competing demands on time. This paper tells the story of a peer reflective group set up for APs and HAPs in the paediatric health psychology team, to provide a supportive space for aspiring psychologists to meet together.

Hippocampal Disinhibition Reduces Contextual and Elemental Fear Conditioning While Sparing the Acquisition of Latent Inhibition.

Hippocampal neural disinhibition, i.e., reduced GABAergic inhibition, is a key feature of schizophrenia pathophysiology.

Brain injury in preterm infants with surgical necrotizing enterocolitis: clinical and bowel pathological correlates.

Background: The objective of this study was to determine the risk factors and outcomes of white matter brain injury (WMBI) on magnetic resonance imaging (MRI) at term-equivalent age in infants with surgical necrotizing enterocolitis (NEC).

Methods: This retrospective study compared clinical/pathological information between infants with and those without WMBI.

Results: Out of 69 infants with surgical NEC, 17 (24.

Flu-like pandemics and metaphor pre-covid: A corpus investigation.

The use of metaphor in framing COVID-19 has already attracted considerable attention in both academic and public debate and we have seen extensive discussion of how this pandemic might be compared to past events, such as the so-called 'Spanish flu' of the 1910s. In this paper, we draw these two strands of metaphoric framing and historical comparison together by identifying the metaphorical framings of past influenza pandemics in media and political discourse in the UK over an extended period (1890-2009). The findings show remarkable continuity in the choice and proportion of conceptual metaphor across very different sociohistorical contexts.

LMA® Gastro™: A paediatric experience.

The laryngeal mask airway, the LMA® Gastro™ (Teleflex Medical, Athlone, Ireland), is a novel airway device which permits upper gastrointestinal (GI) endoscopy to be performed via a dedicated large calibre oesophageal lumen. It has been validated in adult studies, but to our knowledge, there have been no data published regarding its use in a paediatric population. Following a brief education programme, the LMA Gastro was introduced on a trial basis at our institution and made freely available.

Use of Herbarium Voucher Specimens To Investigate Phytochemical Composition in Poisonous Plant Research.

Poisonous plants cause large losses to the livestock industry through death, reduced production efficiency, reproductive dysfunction, and compromised harvesting of rangeland and pasture forages. Research investigating poisonous plants is complex because there are hundreds of genera of toxic plants representing thousands of species. To investigate the effects of poisonous plants on livestock, a clear understanding of the taxonomic identity of the plant and the ability to collect the plant in sufficient quantities for scientific studies is required.

Problematic usage of the internet and eating disorder and related psychopathology: A multifaceted, systematic review and meta-analysis.

Eating disorders are widespread illnesses with significant impact. There is growing concern about how those at risk of eating disorders overuse online resources to their detriment. We conducted a pre-registered systematic review and meta-analysis of studies examining Problematic Usage of the Internet (PUI) and eating disorder and related psychopathology.
