Associations of maternal peripregnancy cannabis use with behavioral and developmental outcomes in children with and without symptoms of autism spectrum disorder: Study to Explore Early Development.

Some studies report increased prevalence of autism spectrum disorder (ASD) and associated symptoms with prenatal cannabis exposure. We examined whether associations of maternal cannabis use from 3 months preconception through delivery ("peripregnancy") with behavior and development in the offspring varied with the presence of ASD symptoms. Children ages 30-68 months with ASD symptoms (i.

Assessment of trochanteric vascularity using quantitative magnetic resonance imaging in a cadaveric model.

Purpose: Few studies have assessed trochanteric vascularity despite its implications for bone healing and surgical approaches. This study aimed to assess the regional arterial contributions of the medial femoral circumflex artery (MFCA) versus the lateral femoral circumflex artery (LFCA) to trochanteric vascularity.

Methods: Ten adult human cadaveric pelvises to mid-femur specimens were obtained.

Transiting to dancing en pointe is an important milestone for young dancers who wish to progress in ballet training. Various criteria exist regarding pointe readiness, including age, range-of-motion, endurance, strength, balance, and technique. However, awareness and use of these criteria by dance instructors is currently unknown.

Amoebic encephalitis within Australia.

Granulomatous amoebic encephalitis is a rare but likely under-recognised form of subacute, usually fatal, encephalitis. We present an illustrative case report and literature review of Australian cases, summarising clinical features, diagnostic methods, treatment and outcomes.

Bidirectional regulation of motor circuits using magnetogenetic gene therapy.

Here, we report a magnetogenetic system, based on a single anti-ferritin nanobody-TRPV1 receptor fusion protein, which regulated neuronal activity when exposed to magnetic fields. Adeno-associated virus (AAV)-mediated delivery of a floxed nanobody-TRPV1 into the striatum of adenosine-2a receptor-Cre drivers resulted in motor freezing when placed in a magnetic resonance imaging machine or adjacent to a transcranial magnetic stimulation device. Functional imaging and fiber photometry confirmed activation in response to magnetic fields.

Use of Intervention Mapping to Adapt a Psychologically Informed Physical Therapy Telerehabilitation Intervention for Latino Persons With Chronic Spine Pain.

The need for culturally tailored pain care is well-recognized, yet few studies report how existing interventions can be adapted to the needs of culturally and linguistically diverse populations. This report describes a formative mixed-methods approach using intervention mapping-adapt and the expanded framework for reporting adaptations and modifications to evidence-based interventions to adapt and report modifications of an existing physical therapy intervention for Latino persons with chronic spine pain in Federally Qualified Health clinics in the southwestern United States. Mixed methods included literature reviews, patient surveys, an Adaptation Advisory Panel, and sequential case series with semistructured interviews.

Quantification of Multi-Compartment Flow with Spectral Diffusion MRI.

Purpose: Estimation of multi-compartment intravoxel 'flow' in in ml/100g/min with multi-b-value diffusion weighted imaging and a multi-Gaussian model in the kidneys.

Theory And Methods: A multi-Gaussian model of intravoxel flow using water transport time to quantify (ml/100g/min) is presented and simulated. Multi-compartment anisotropic DWI signal is simulated with Rician noise and SNR=50 and analyzed with a rigid bi-exponential, a rigid tri-exponential and diffusion spectrum imaging model of intravoxel incoherent motion (spectral diffusion) to study extraction of multi-compartment flow.

Structure and fragmentation of doubly ionized HNCS.

Double ionization spectra of isothiocyanic acid (HNCS) have been measured using multi-electron and multi-ion coincidence techniques combined with high-level theoretical calculations. The adiabatic double ionization energy of HNCS is found at 27.1 ± 0.

Quantitative-MRI analysis of the effects of retrograde nailing on vascularity of the distal femur: A cadaveric study.

Background: Distal femur fractures remain treatment challenges with a considerable postoperative non-union rate. Concern remains that surgery may compromise osseous vascularity. This study aimed to determine effects of retrograde femoral intramedullary nailing (RFIN) on distal femur vascularity, and the locations of the middle genicular artery terminal branches in relation to the standard RFIN entry point.

The CCL2-CCR4 axis promotes Regulatory T cell trafficking to canine glioma tissues.

Purpose: Spontaneously occurring glioma in pet dogs is increasingly recognized as a valuable translational model for human glioblastoma. Canine high-grade glioma and human glioblastomas share many molecular similarities, including the accumulation of immunosuppressive regulatory T cells (Tregs) that inhibit anti-tumor immune responses. Identifying in dog mechanisms responsible for Treg recruitment may afford to target the cellular population driving immunosuppression, the results providing a rationale for translational clinical studies in human patients.

In vivo brain estrogen receptor density by neuroendocrine aging and relationships with cognition and symptomatology.

17β-estradiol, the most biologically active estrogen, exerts wide-ranging effects in brain through its action on estrogen receptors (ERs), influencing higher-order cognitive function and neurobiological aging. However, our knowledge of ER expression and regulation by neuroendocrine aging in the living human brain is limited. This in vivo brain F-fluoroestradiol (F-FES) Positron Emission Tomography (PET) study of healthy midlife women reveals progressively higher ER density over the menopause transition in estrogen-regulated networks.

Child Age at Time of First Maternal Concern and Time to Services Among Children with Autism Spectrum Disorder.

Objective: Early treatment of autism spectrum disorder (ASD) can improve developmental outcomes. Children with ASD from minority families often receive services later. We explored factors related to child's age at time of mother's first concerns about child's development and subsequent time to service initiation among children with ASD.

Maternal diet influences fecundity in a freshwater turtle undergoing population decline.

Food availability determines the amount of energy animals can acquire and allocate to reproduction and other necessary functions. Female animals that are food limited thus experience reduced energy available for reproduction. When this occurs, females may reduce frequency of reproductive events or the number or size of offspring per reproductive bout.

Prosodic features in production reflect reading comprehension skill in high school students.

Young children's prosodic fluency correlates with their reading ability, as children who are better early readers also produce more adult-like prosodic cues to syntactic and semantic structure. But less work has explored this question for high school readers, who are more proficient readers, but still exhibit wide variability in reading comprehension skill and prosodic fluency. In the current study, we investigated acoustic indices of prosodic production in high school students ( = 40; ages 13-19) exhibiting a range of reading comprehension skill.

Is Osteoarthritis a Vascular Disease?

Osteoarthritis (OA) is now considered as a multifaceted disease affecting various articular tissues, including cartilage, bone, synovium, and surrounding ligaments. The pathophysiology strongly implicates intricate chemical communication, primarily through cytokines, leading to the production of degradative enzymes in cartilage, inflammatory peptides in synovium, and structural changes in bone, resulting in characteristic clinical features such as joint deformities and loss of cartilage space seen on X-rays. Recent studies highlight the previously underestimated role of subchondral bone in OA, revealing its permeability to cytokines and raising questions about the influence of abnormal perfusion on OA pathophysiology, suggesting a vascular component in the disease's etiology.

Paternal protein provisioning to embryos during male seahorse pregnancy.

In Brief: Seahorses exhibit male pregnancy and are thus valuable comparative models for the study of the physiology and evolution of pregnancy. This study shows that protein is transported from fathers to developing embryos during gestation, and provides new knowledge about paternal contributions to embryonic development.

Abstract: Syngnathid embryos (seahorses, pipefishes and seadragons) develop on or in the male in a specialised brooding structure (brood pouch).

Factors associated with satisfaction with physical therapy services - a survey of patients with musculoskeletal pain at a federally qualified health center.

Methods: Patients > 18 years of age, English or Spanish speakers, referred to PT were invited to complete an online survey. Factors that may influence PT satisfaction were examined for patients who attended PT.

Safety and efficacy of cerliponase alfa in children with neuronal ceroid lipofuscinosis type 2 (CLN2 disease): an open-label extension study.

Background: Cerliponase alfa is a recombinant human tripeptidyl peptidase 1 (TPP1) enzyme replacement therapy for the treatment of neuronal ceroid lipofuscinosis type 2 (CLN2 disease), which is caused by mutations in the TPP1 gene. We aimed to determine the long-term safety and efficacy of intracerebroventricular cerliponase alfa in children with CLN2 disease.

Methods: This analysis includes cumulative data from a primary 48-week, single-arm, open-label, multicentre, dose-escalation study (NCT01907087) and the 240-week open-label extension with 6-month safety follow-up, conducted at five hospitals in Germany, Italy, the UK, and the USA.

Synthesis, Characterization, and Computational Studies on Gallium(III) and Iron(III) Complexes with a Pentadentate Macrocyclic -Phosphinate Chelator and Their Investigation As Molecular Scaffolds for F Binding.

With the aim of obtaining improved molecular scaffolds for F binding to use in PET imaging, gallium(III) and iron(III) complexes with a macrocyclic -phosphinate chelator have been synthesized and their properties, including their fluoride binding ability, investigated. Reaction of Bn-tacn (1-benzyl-1,4,7-triazacyclononane) with paraformaldehyde and PhP(OR) (R = Me or Et) in refluxing THF, followed by acid hydrolysis, yields the macrocyclic (phosphinic acid) derivative, H(Bn-NODP) (1-benzyl-4,7-phenylphosphinic acid-1,4,7-triazacyclononane), which is isolated as its protonated form, H(Bn-NODP)·2HCl·4HO, at low pH (HCl), its disodium salt, Na(Bn-NODP)·5HO at pH 12 (NaOH), or the neutral H(Bn-NODP) under mildly basic conditions (EtN). A crystal structure of H(Bn-NODP)·2HCl·HO confirmed the ligand's identity.
