Developing a core outcome set for the health outcomes for children and adults with congenital oesophageal atresia and/or tracheo-oesophageal fistula: OCELOT task group study protocol.

Introduction: Heterogeneity in reported outcomes of infants with oesophageal atresia (OA) with or without tracheo-oesophageal fistula (TOF) prevents effective data pooling. Core outcome sets (COS) have been developed for many conditions to standardise outcome reporting, facilitate meta-analysis and improve the relevance of research for patients and families. Our aim is to develop an internationally-agreed, comprehensive COS for OA-TOF, relevant from birth through to transition and adulthood.

Nestling Begging Calls Resemble Maternal Vocal Signatures When Mothers Call Slowly to Embryos.

AbstractVocal production learning (the capacity to learn to produce vocalizations) is a multidimensional trait that involves different learning mechanisms during different temporal and socioecological contexts. Key outstanding questions are whether vocal production learning begins during the embryonic stage and whether mothers play an active role in this through pupil-directed vocalization behaviors. We examined variation in vocal copy similarity (an indicator of learning) in eight species from the songbird family Maluridae, using comparative and experimental approaches.

Prevalence and early surgical outcome of congenital diaphragmatic hernia in the Netherlands: a population-based cohort study from the European Pediatric Surgical Audit.

Background: Congenital diaphragmatic hernia (CDH) is a rare birth defect with substantial mortality. This study aims to generate a population-based overview of CDH care and outcomes in the Netherlands. Moreover, it assesses interhospital variations between the two Dutch CDH expert centres.

Selection of Quality Indicators to Evaluate Quality of Care for Patients with Esophageal Atresia Using a Delphi Method.

Objective:  Survival of neonates with esophageal atresia (EA) is relatively high and stable, resulting in increased attention to optimizing care and longer-term morbidity. This study aimed to reach consensus on a quality indicator set for benchmarking EA care between hospitals, regions, or countries in a European clinical audit.

Methods:  Using an online Delphi method, a panel of EA health care professionals and patient representatives rated potential outcome, structure, and process indicators for EA care identified through systematic literature and guideline review on a nine-point Likert scale in three questionnaires.

Best of both worlds? Helpers in a cooperative fairy-wren assist most to breeding pairs that comprise a potential mate and a relative.

In cooperative breeders, individuals forego independent reproduction and help others raise offspring. Helping is proposed to be driven by indirect benefits from raising relatives, and/or direct benefits from raising additional recruits or helping itself. We propose that consideration of social context is also important, in particular the characteristics of the breeding pair: helping may also serve to lighten the workload of-or maintain social bonds with-breeders (e.

Bridging the Gap: A Systematic Review on Reporting Baseline Characteristics, Process, and Outcome Parameters in Rectosigmoid Hirschsprung's Disease.

The variation in standardized, well-defined parameters in Hirschsprung's disease (HSCR) research hinders overarching comparisons and complicates evaluations of care quality across healthcare settings. This review addresses the significant variability observed in these parameters as reported in recent publications. The goal is to compile a list of commonly described baseline characteristics, process and outcome measures, and to investigate disparities in their utilization and definitions.

Variability in the Reporting of Baseline Characteristics, Treatment, and Outcomes in Esophageal Atresia Publications: A Systematic Review.

Introduction:  As survival rates of infants born with esophageal atresia (EA) have improved considerably, research interests are shifting from viability to morbidity and longer-term outcomes. This review aims to identify all parameters studied in recent EA research and determine variability in their reporting, utilization, and definition.

Materials And Methods:  Following PRISMA guidelines, we performed a systematic review of literature regarding the main EA care process, published between 2015 and 2021, combining the search term "esophageal atresia" with "morbidity," "mortality," "survival," "outcome," or "complication.

Outcome of functional treatment with a Lucerne Cast in patients with hand fractures: a retrospective case series.

Purpose: The purpose of this study was to determine the clinical outcome of patients treated with a functional Lucerne Cast (LuCa) for different types of hand fractures. Static casting has traditionally been the preferred treatment for hand fractures. However, functional casting may lead to good functional outcomes, less stiffness, and earlier return to work.

Development and validation of a condition-specific quality of life instrument for adults with esophageal atresia: the SQEA questionnaire.

The importance of multidisciplinary long-term follow-up for adults born with esophageal atresia (EA) is increasingly recognized. Hence, a valid, condition-specific instrument to measure health-related quality of life (HRQoL) becomes imperative. This study aimed to develop and validate such an instrument for adults with EA.

Hot and dry conditions predict shorter nestling telomeres in an endangered songbird: Implications for population persistence.

Climate warming is increasingly exposing wildlife to sublethal high temperatures, which may lead to chronic impacts and reduced fitness. Telomere length (TL) may link heat exposure to fitness, particularly at early-life stages, because developing organisms are especially vulnerable to adverse conditions, adversity can shorten telomeres, and TL predicts fitness. Here, we quantify how climatic and environmental conditions during early life are associated with TL in nestlings of wild purple-crowned fairy-wrens (), endangered songbirds of the monsoonal tropics.

Telomere length declines with age, but relates to immune function independent of age in a wild passerine.

Telomere length (TL) shortens with age but telomere dynamics can relate to fitness components independent of age. Immune function often relates to such fitness components and can also interact with telomeres. Studying the link between TL and immune function may therefore help us understand telomere-fitness associations.

No Evidence for Constitutive Innate Immune Senescence in a Longitudinal Study of a Wild Bird.

AbstractAging is associated with declines in physiological performance; declining immune defenses particularly could have consequences for age-related fitness and survival. In aging vertebrates, adaptive (memory-based) immune responses typically become impaired, innate (nonspecific) responses undergo lesser declines, and inflammation increases. Longitudinal studies of immune functions in wild animals are rare, yet they are needed to understand immunosenescence under evolutionarily relevant conditions.

Telomere dynamics in the first year of life, but not later in life, predict lifespan in a wild bird.

Telomeres are protective, nucleoprotein structures at the end of chromosomes that have been associated with lifespan across taxa. However, the extent to which these associations can be attributed to absolute length vs. the rate of telomere shortening prior to sampling remains unresolved.

Context-dependent social benefits drive cooperative predator defense in a bird.

Understanding the major evolutionary transition from solitary individuals to complex societies is hampered by incomplete insight into the drivers of living in cooperative groups. This may be because the benefits of sociality can derive from group living itself (e.g.

Fitness outcomes in relation to individual variation in constitutive innate immune function.

Although crucial for host survival when facing persistent parasite pressure, costly immune functions will inevitably compete for resources with other energetically expensive traits such as reproduction. Optimizing, but not necessarily maximizing, immune function might therefore provide net benefit to overall host fitness. Evidence for associations between fitness and immune function is relatively rare, limiting our potential to understand ultimate fitness costs of immune investment.

Sleep slow-wave homeostasis and cognitive functioning in children with electrical status epilepticus in sleep.

Study Objectives: Encephalopathy with electrical status epilepticus in sleep (ESES) is characterized by non-rapid eye movement (non-REM)-sleep-induced epileptiform activity and acquired cognitive deficits. The synaptic homeostasis hypothesis describes the process of daytime synaptic potentiation balanced by synaptic downscaling in non-REM-sleep and is considered crucial to retain an efficient cortical network. We aimed to study the overnight decline of slow waves, an indirect marker of synaptic downscaling, in patients with ESES and explore whether altered downscaling relates to neurodevelopmental and behavioral problems.

Short-Term Climate Variation Drives Baseline Innate Immune Function and Stress in a Tropical Bird: A Reactive Scope Perspective.

Investment in immune function can be costly, and life-history theory predicts trade-offs between immune function and other physiological demands. Environmental heterogeneity may constrain or change the optimal strategy and thereby alter baseline immune function (possibly mediated by stress responses). We tested several hypotheses relating variation in climatic, ecological, and social environments to chronic stress and levels of baseline innate immunity in a wild, cooperatively breeding bird, the purple-crowned fairy-wren (Malurus coronatus coronatus).

Early-life telomere length predicts lifespan and lifetime reproductive success in a wild bird.

Poor conditions during early development can initiate trade-offs that favour current survival at the expense of somatic maintenance and subsequently, future reproduction. However, the mechanisms that link early and late life-history are largely unknown. Recently it has been suggested that telomeres, the nucleoprotein structures at the terminal end of chromosomes, could link early-life conditions to lifespan and fitness.

Specific EEG markers in POLG1 Alpers' syndrome.

Objective: To examine whether rhythmic high-amplitude delta with superimposed (poly)spikes (RHADS) in EEG allow a reliable early diagnosis of Alpers-Huttenlocher syndrome (AHS) and contribute to recognition of this disease.

Methods: EEGs of nine patients with DNA-proven AHS and fifty age-matched patients with status epilepticus were retrospectively examined by experts for the presence of RHADS and for accompanying clinical signs and high-frequency ripples. Reproducibility of RHADS identification was tested in a blinded panel.

From ornament to armament or loss of function? Breeding plumage acquisition in a genetically monogamous bird.

The evolution of conspicuous male traits is thought to be driven by female mate choice or male-male competition. These two mechanisms are often viewed as distinct processes, with most studies focusing on female choice. However, both mechanisms of sexual selection can act simultaneously on the same trait (i.

Bright birds are cautious: seasonally conspicuous plumage prompts risk avoidance by male superb fairy-wrens.

Increased predation risk is considered a cost of having conspicuous colours, affecting the anti-predator behaviour of colourful animals. However, this is difficult to test, as individual factors often covary with colour and behaviour. We used alarm call playback and behavioural observations to assess whether individual birds adjust their response to risk according to their plumage colour.

Various expression-augmenting DNA elements benefit from STAR-Select, a novel high stringency selection system for protein expression.

The creation of highly productive mammalian cell lines often requires the screening of large numbers of clones, and even then expression levels are often low. Previously, we identified DNA elements, anti-repressor or STAR elements, that increase protein expression levels. These positive effects of STAR elements are most apparent when stable clones are established under high selection stringency.
