Using damage functions to map heritage climatology at a global scale.

This paper investigates heritage climatology through global analysis of damage functions for collections, aiming to learn about the reliability of these functions and the field itself. It addresses the growing interest in geospatial analysis of climate hazards for cultural heritage, proposing parameters that refine climate-related deterioration processes. Using global daily climate data from 1991 to 2020, the study assesses damage functions reliant on temperature and relative humidity inputs, including damage functions for paper and metals, alongside indices for humidity fluctuations and mould growth.

Clinical Spectrum and Prognosis of Atypical Autosomal Dominant Polycystic Kidney Disease Caused by Monoallelic Pathogenic Variants of IFT140.

Rationale & Objective: Monoallelic predicted Loss-of-Function (pLoF) variants in IFT140 have recently been associated with an autosomal dominant polycystic kidney disease (ADPKD)-like phenotype. This study sought to enhance the characterization of this phenotype.

Study Design: Case series.

Copy-number analysis from genome sequencing data of 11,754 rare-disease parent-child trios: A model for identifying autosomal recessive human gene knockouts including a novel gene for autosomal recessive retinopathy.

Purpose: In parent-child trios with genome sequencing data, we investigated inherited biallelic deletions to identify known and novel genetic disorders.

Methods: We developed a copy-number variations analysis pipeline based on autosomal genome sequencing read depth of Genomics England 100,000 Genomes Project data from 11,754 parent-child trios and additional 18,875 non-trios. A control cohort of 15,440 cancer patients provided independent deletion frequencies.

REM disruption and REM vagal activity predict extinction recall in trauma-exposed individuals.

Background: Accumulating evidence suggests that rapid eye movement sleep (REM) supports the consolidation of extinction memory. REM is disrupted in posttraumatic stress disorder (PTSD), and REM abnormalities after traumatic events increase the risk of developing PTSD. Therefore, it was hypothesized that abnormal REM in trauma-exposed individuals may pave the way for PTSD by interfering with the processing of extinction memory.

Altered post-fracture systemic bone loss in a mouse model of osteocyte dysfunction.

Femur fracture leads to loss of bone at uninjured skeletal sites, which may increase risk of subsequent fracture. Osteocytes, the most abundant bone cells, can directly resorb bone matrix and regulate osteoclast and osteoblast activity, but their role in systemic bone loss after fracture remains poorly understood. In this study we used a transgenic (TG+) mouse model that overexpresses human B-cell lymphoma 2 (BCL-2) in osteoblasts and osteocytes.

Card9 and MyD88 differentially regulate Th17 immunity to the commensal yeast Malassezia in the murine skin.

The fungal community of the skin microbiome is dominated by a single genus, Malassezia. Besides its symbiotic lifestyle at the host interface, this commensal yeast has also been associated with diverse inflammatory skin diseases in humans and pet animals. Stable colonization is maintained by antifungal type 17 immunity.

Remote electrical neuromodulation to treat children and adolescents with migraine in the emergency department: A randomized double-dummy pilot trial.

Objective: Using a double-dummy pilot randomized controlled trial design, we aimed to determine the feasibility and acceptability of comparing remote electrical neuromodulation (REN) to typical care intravenous pharmacologic interventions for the treatment of children and adolescents visiting the emergency department (ED) with migraine, and to compare parallel-group versus crossover trial designs.

Background: There are limited data to guide the management of migraine in the ED. Children and adolescents are interested in neuromodulation, and specifically REN, for treatment in this setting, but there are no existing data on this approach.

Comparison of autonomic reactivity to trauma and nightmare imagery: A Pilot Study.

Study Objectives: Trauma-related nightmares (TRNs) are a hallmark symptom of PTSD and are highly correlated with PTSD severity and poor sleep quality. Given the salience and arousal associated with TRNs, they might be an effective target for imaginal exposures during Prolonged Exposure (PE) therapy. As a first step in this line of research, the current study compared participants' emotional reactivity during recollection of TRNs to their recollection of the index traumatic event.

The safety and efficacy of onabotulinumtoxinA injections for children and adolescents with chronic migraine: A systematic review and meta-analysis.

Objective: To qualitatively and quantitatively summarize the evidence for the use of onabotulinumtoxinA injections in children and adolescents with migraine.

Background: There are limited evidence-based treatment options for youth with migraine, especially youth with chronic migraine (CM). OnabotulinumtoxinA injections are an established evidence-based treatment for adults with CM.

Is Routine Pathology Evaluation of Tissue Removed for Fertility Preservation Necessary?

Background: For all fertility preservation (FP) cases at our institution, a biopsy is performed for routine pathology from all gonadal tissue removed. This is not standard at all centers. We reviewed our experience with biopsy for pathological evaluation of ovarian and testicular specimens in FP cases to determine clinical utility.

Early childhood risk factors for later onset of pediatric chronic pain: a multi-method longitudinal study.

Background: Pediatric chronic pain (i.e., pain lasting ≥ 3 months) is prevalent, disabling, and costly.

The fungal community of the skin microbiome is dominated by a single genus, . Besides its symbiotic lifestyle at the host interface, this commensal yeast has also been associated with diverse inflammatory skin diseases in humans and pet animals. Stable colonization is maintained by antifungal type 17 immunity.

Clinical factors associated with day-to-day peak pain severity in individuals with chronic migraine: A cohort study using daily prospective diary data.

Objective: To describe the association between day-to-day peak pain severity and clinical factors in individuals with chronic migraine (CM).

Background: Little is known about how clinical factors relate to day-to-day pain severity in individuals with CM.

Methods: Adults with CM were enrolled into this observational prospective cohort study that collected daily data about headache, associated symptoms, and lifestyle factors using a digital health platform (N1-Headache™) for 90 days.

Variation in Freshwater Insect Osmoregulatory Traits: A Comparative Approach.

AbstractFreshwater salinity regimes vary naturally and are changing in response to anthropogenic activities. Few insect species tolerate saline waters, and biodiversity losses are associated with increasing salinity in freshwater. We used radiotracers (Na, SO, and Ca) to examine ion uptake rates across concentration gradients in mayflies (Ephemeroptera), caddis flies (Trichoptera), and mosquitoes (Diptera) and made observations for some traits in seven other taxa representing mayflies, stone flies (Plecoptera), true flies (Diptera), and true bugs (Hemiptera).

Region-specific changes in brain glutamate and gamma-aminobutyric acid across the migraine attack in children and adolescents.

In patients with migraine, an excitation-inhibition imbalance that fluctuates relative to attack onset has been proposed to contribute to the underlying pathophysiology of migraine, but this has yet to be explored in children and adolescents. This prospective, observational, cohort study examined glutamate and gamma-aminobutyric acid (GABA) levels across the phases of a migraine attack and interictally in children and adolescents using magnetic resonance spectroscopy. Macromolecule-suppressed GABA (sensorimotor cortex and thalamus) and glutamate (occipital cortex, sensorimotor cortex, and thalamus) were measured in children and adolescents (10-17 years) with a migraine diagnosis with or without aura 4 times over 2 weeks.

The 2023 protocol for update to acute treatment of adults with migraine in the emergency department: The American Headache Society evidence assessment of parenteral pharmacotherapies.

Objectives: The primary objective of this proposed guideline is to update the prior 2016 guideline on parenteral pharmacotherapies for the management of adults with a migraine attack in the emergency department (ED).

Methods: We will conduct an updated systematic review and meta-analysis using the 2016 guideline methodology to provide clinical recommendations. The same search strategy will be used for studies up to 2023, with a new search strategy added to capture studies of nerve blocks and sphenopalatine blocks.

Evaluating patient and family preferences for acute and preventive pediatric headache treatment.

Objective: To describe acute and preventive treatment preferences among youth with migraine and their parents/guardians, and to describe the degree of youth-parent/guardian preference agreement.

Background: Headache disorders are common in youth, but little is known about patient and family preferences for headache treatments and outcomes.

Methods: In this cross-sectional survey, a headache treatment preferences questionnaire was co-created with stakeholders, piloted, and distributed to consenting youth with migraine aged 9-18 years and parents/guardians at a tertiary care headache clinic in western Canada.

Epigenetic mechanisms of osteoarthritis risk in human skeletal development.

The epigenome, including the methylation of cytosine bases at CG dinucleotides, is intrinsically linked to transcriptional regulation. The tight regulation of gene expression during skeletal development is essential, with ~1/500 individuals born with skeletal abnormalities. Furthermore, increasing evidence is emerging to link age-associated complex genetic musculoskeletal diseases, including osteoarthritis (OA), to developmental factors including joint shape.
