Is temporal synchrony necessary for effective Batesian mimicry?

Batesian mimicry occurs when palatable mimics gain protection from predators by evolving a phenotypic resemblance to an aposematic model species. While common in nature, the mechanisms maintaining mimicry are not fully understood. Patterns of temporal synchrony (i.

Paediatric trauma and hypocalcaemia: a systematic review.

Background: Trauma is a leading cause of mortality and morbidity in children worldwide. While adult studies have demonstrated hypocalcaemia's association with adverse outcomes, its impact on paediatric trauma patients remains understudied. This systematic review aims to investigate current evidence into the prevalence, clinical implications and associations of hypocalcaemia in paediatric trauma.

Decoding Depth of Meditation: Electroencephalography Insights From Expert Vipassana Practitioners.

Effects of Physical Exercise Breaks on Executive Function in a Simulated Classroom Setting: Uncovering a Window into the Brain.

Acknowledging the detrimental effects of prolonged sitting, this study examined the effects of an acute exercise break during prolonged sitting on executive function, cortical hemodynamics, and microvascular status. In this randomized crossover study, 71 college students completed three conditions: (i) uninterrupted sitting (SIT); (ii) SIT with a 15 min moderate-intensity cycling break (MIC); and (iii) SIT with a 15 min vigorous-intensity cycling break (VIC). Behavioral outcomes, retinal vessel diameters (central retinal artery equivalents [CRAE], retinal vein equivalents [CRVE], arteriovenous ratio [AVR]), cortical activation, and effective connectivity were evaluated.

The Definition of Failure in Hip Arthroscopy May Include Factors Outside of Reoperation: A Systematic Review.

Purpose: To perform a systematic review about the varying definitions of "failure" of hip arthroscopy (HA) in the current literature and to provide a recommendation for the standardization of defining failure of HA.

Methods: A systematic search of electronic databases was conducted to identity Level I-IV clinical studies on HA failure published between January 2016 and July 2021 according to Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Inclusion criteria consisted of studies of patients who underwent an arthroscopic hip procedure and included a definition of failure.

Imaging body-mind crosstalk in young adults.

Objective: There is evidence that complex relationships exist between motor functions, brain structure, and cognitive functions, particularly in the aging population. However, whether such relationships observed in older adults could extend to other age groups (e.g.

Decoding working-memory load during-back task performance from high channel fNIRS data.

Functional near-infrared spectroscopy (fNIRS) can measure neural activity through blood oxygenation changes in the brain in a wearable form factor, enabling unique applications for research in and outside the lab and in practical occupational settings. fNIRS has proven capable of measuring cognitive states such as mental workload, often using machine learning (ML) based brain-computer interfaces (BCIs). To date, this research has largely relied on probes with channel counts from under ten to several hundred, although recently a new class of wearable NIRS devices featuring thousands of channels has emerged.

A produce prescription program for patients with low incomes in North Carolina resulted in increased produce purchases.

Objectives: To assess if participation in a North Carolina produce prescription program for Supplemental Nutrition Assistance Program (SNAP) participants with diet-sensitive health conditions (SuperSNAP) is associated with changes in purchase composition and spending source.

Methods: This study used loyalty-card transaction data (October 2019-April 2022). We applied a linear mixed-effects model with overlap weights to perform a difference-indifferences analysis of purchases by SuperSNAP program enrollees compared to the control group.

Utility of Artificial Intelligence Plaque Quantification: Results of the DECODE Study.

Background: Artificial Intelligence Plaque Analysis (AI-QCPA, HeartFlow) provides, from a CCTA, quantitative plaque burden information including total plaque and plaque subtype volumes. We sought to evaluate the clinical utility of AI-QCPA in clinical decision making.

Methods: One hundred cases were reviewed by 3 highly experienced practicing cardiologists who are SCCT level 3 CCTA readers.

Experience of the first adult-focussed undiagnosed disease program in Australia (AHA-UDP): solving rare and puzzling genetic disorders is ageless.

Background: Significant recent efforts have facilitated increased access to clinical genetics assessment and genomic sequencing for children with rare diseases in many centres, but there remains a service gap for adults. The Austin Health Adult Undiagnosed Disease Program (AHA-UDP) was designed to complement existing UDP programs that focus on paediatric rare diseases and address an area of unmet diagnostic need for adults with undiagnosed rare conditions in Victoria, Australia. It was conducted at a large Victorian hospital to demonstrate the benefits of bringing genomic techniques currently used predominantly in a research setting into hospital clinical practice, and identify the benefits of enrolling adults with undiagnosed rare diseases into a UDP program.

Intensive care unit improves dialysis care quality while reducing costs.

Aims And Background: The current report details transition of outsourced conventional dialysis therapy in the ICU services to an in-house prolonged intermittent renal replacement therapy (PIRRT) service model as a quality improvement project using the Tablo Hemodialysis System, Outset Medical, Inc. The goals were aimed at maintaining or improving clinical outcomes, while also reducing dialysis-related nursing staff burden and dialysis-related treatment costs.

Methods: A descriptive comparative analysis was conducted of renal replacement therapy (RRT) of ≥6 hours in duration performed in the 1 year prior and 1 year after the ICU's in-house program launch using a PIRRT model including sequential 24-h treatments when medically necessary.

The Benefits of Acute Exercise for Children's Cognition Are Associated with Trait Anxiety.

Introduction: Children's anxiety is associated with decreased cognitive performance. One well-established behavioral intervention to transiently improve cognitive performance in children is acute aerobic exercise (AAE). Thus far, however, it is unclear whether the benefits of AAE on cognition vary based on individual differences in children's anxiety level.

Prospective deep learning-based quantitative assessment of coronary plaque by computed tomography angiography compared with intravascular ultrasound: the REVEALPLAQUE study.

Aims: Coronary computed tomography angiography provides non-invasive assessment of coronary stenosis severity and flow impairment. Automated artificial intelligence (AI) analysis may assist in precise quantification and characterization of coronary atherosclerosis, enabling patient-specific risk determination and management strategies. This multicentre international study compared an automated deep learning-based method for segmenting coronary atherosclerosis in coronary computed tomography angiography (CCTA) against the reference standard of intravascular ultrasound (IVUS).

Sex differences in interacting genetic and functional connectivity biomarkers in Alzheimer's disease.

As of 2023, it is estimated that 6.7 million individuals in the United States live with Alzheimer's disease (AD). Prior research indicates that AD disproportionality affects females; females have a greater incidence rate, perform worse on a variety of neuropsychological tasks, and have greater total brain atrophy.

On decoding of rapid motor imagery in a diverse population using a high-density NIRS device.

Introduction: Functional near-infrared spectroscopy (fNIRS) aims to infer cognitive states such as the type of movement imagined by a study participant in a given trial using an optical method that can differentiate between oxygenation states of blood in the brain and thereby indirectly between neuronal activity levels. We present findings from an fNIRS study that aimed to test the applicability of a high-density (>3000 channels) NIRS device for use in short-duration (2 s) left/right hand motor imagery decoding in a diverse, but not explicitly balanced, subject population. A side aim was to assess relationships between data quality, self-reported demographic characteristics, and brain-computer interface (BCI) performance, with no subjects rejected from recruitment or analysis.

Independent Plastic Surgery Match Regional Trends Comparing In-person and Virtual Interview Cycles.

Background: There is a trend toward matching in a different region than previous training for the independent plastic surgery match cycles from 2019 to 2021, which differs from the trend to match within the same region for integrated plastic surgery programs. Notably, residency interviews transitioned from in-person to virtual in 2020 due to the coronavirus pandemic. Therefore, we compared in-person versus virtual interview match trends from 2019 to 2023.

Breathing control training for functional seizures: A multi-site, open-label pilot study.

There are no well-validated treatments for functional seizures. While specialist psychotherapy is usually recommended, the evidence for its benefit is qualified, and it can be difficult to obtain. Given the association between hyperventilation and functional seizures we explored an alternative modality, breathing control training, in a multi-site open label pilot trial.

An iPSC line (FINi003-A) from a male with late-onset developmental and epileptic encephalopathy caused by a heterozygous p.E1211K variant in the SCN2A gene encoding the voltage-gated sodium channel Na1.2.

Many developmental and epileptic encephalopathies (DEEs) result from variants in cation channel genes. Using mRNA transfection, we generated and characterised an induced pluripotent stem cell (iPSC) line from the fibroblasts of a male late-onset DEE patient carrying a heterozygous missense variant (E1211K) in Na1.2(SCN2A) protein.
