Assessing sport commitment: the development and preliminary validation of recreational sport commitment questionnaire.

Background: Presently, where inactivity is an overarching problem globally, participation in recreational sports activities has become an important outlet for promoting healthy lifestyles. However, there is a lack of instruments to evaluate the commitment of recreational and leisure sports users. This study aimed to adapt, develop and provide preliminary validation of the Recreational Sport Commitment Questionnaire (RESQ).

Association of Self-Expanding Valves with Increased Capture of Larger Debris by Cerebral Protection System in Transcatheter Aortic Valve Replacement for Severe Aortic Stenosis.

Background: Mixed evidence exists regarding stroke rates when comparing self-expanding valves (SEVs) to balloon-expandable valves (BEVs) in transcatheter aortic valve replacement (TAVR). This study investigates the debris captured by the SENTINEL cerebral protection system (CPS) during TAVR.

Methods: Seventy-five consecutive patients who underwent TAVR with CPS from March to December 2023 were recruited.

Primary Paraganglioma Arising From the Maxillary Bone.

We present a unique case of primary intraosseous paraganglioma (PGL) originating from maxillary bone. PGL is a neurosecretory neoplasm that arises from cells believed to originate from the neural crest. A 30-year-old woman presented with right facial pain and swelling, along with palpitations.

Intraoperative Spinal Accessory Nerve Monitoring During Neck Dissection Surgery as a Predictor for Shoulder Dysfunction.

Shoulder dysfunction is one of the most common complications seen in patients who have undergone neck dissection surgery. The prevalence of shoulder dysfunction increases depending on the type and extent of neck dissection surgery. We aim to study the relationship between changes in intraoperative neuromonitoring (IONM) threshold during SAN stimulation, ultrasonographic measurement of muscle size and shear wave elastography with shoulder dysfunction.

Central Hearing Loss in a Pediatric Patient.

Sensorineural hearing loss is typically caused by dysfunction of the inner ear or auditory nerve. In pediatric patients diagnosed with sensorineural hearing loss, work-up often includes genetic testing and imaging studies of the auditory pathway. Here, we report a case of a pediatric patient with a history of sensorineural hearing loss following cisplatin and radiation therapy for brainstem medulloblastoma, developing symptoms and signs of central hearing loss based on audiometric and MRI/diffusion tensor imaging studies.

Is the ulnar fovea sign positive only in foveal tears of the triangular fibrocartilage complex?

A positive ulnar fovea sign is usually considered to be specific for foveal disruption of the distal radioulnar ligaments. A retrospective review was done of 73 patients with a positive ulnar fovea sign. Only 21 patients had a foveal tear on arthroscopic examination.

Identification of PANoptosis-relevant subgroups and predicting signature to evaluate the prognosis and immune landscape of patients with biliary tract cancer.

Background: This study conducted molecular subtyping of biliary tract cancer patients based on 19 PANoptosis-related gene signatures.

Methods: Through consensus clustering, patients were categorized into two subtypes, A and B. By integrating multi-omics data and clinical information from different cohorts, we elucidated the association between different subtypes of biliary tract cancer and patient prognosis, which correlated with the immune infiltration characteristics of patients.

Mesenchymal stem cells as future treatment for cardiovascular regeneration and its challenges.

Cardiovascular diseases (CVDs), particularly stroke and myocardial infarction (MI) contributed to the leading cause of death annually among the chronic diseases globally. Despite the advancement of technology, the current available treatments mainly served as palliative care but not treating the diseases. However, the discovery of mesenchymal stem cells (MSCs) had gained a consideration to serve as promising strategy in treating CVDs.

Single-cell transcriptomic atlas reveals increased regeneration in diseased human inner ear balance organs.

Mammalian inner ear hair cell loss leads to permanent hearing and balance dysfunction. In contrast to the cochlea, vestibular hair cells of the murine utricle have some regenerative capacity. Whether human utricular hair cells regenerate in vivo remains unknown.

Could it have been predicted? A retrospective analysis of the last year of life for people who died whilst in an intermediate care centre.

Objectives: Intermediate care centres (ICCs) exist in the UK to bridge between acute hospital and home for those with rehabilitation needs. A national study shows 25% of ICC in-patients died within a year of admission. High quality end-of-life care includes early conversations with a person and their loved ones about what matters to them; timely identification of those who are likely to be nearing the end of their life is key.

The interplay of growth-regulating factor 5 and BZR1 in coregulating chlorophyll degradation in poplar.

Chlorophyll (Chl) is essential for plants to carry out photosynthesis, growth and development processes. Growth-regulating factors (GRFs) play a vital role in regulating Chl degradation in plants. However, the molecular mechanism by which GRF5 regulates Chl degradation in poplar remains unknown.

A privacy-preserving publicly verifiable quantum random number generator.

Verifying the quality of a random number generator involves performing computationally intensive statistical tests on large data sets commonly in the range of gigabytes. Limitations on computing power can restrict an end-user's ability to perform such verification. There are also random number-based applications where an honest user needs to publicly demonstrate that the random bits they are using pass the statistical tests without the bits being revealed.

Diagnostic performance of [Ga]DOTATATE PET/CT, [F]FDG PET/CT, MRI of the spine, and whole-body diagnostic CT and MRI in the detection of spinal bone metastases associated with pheochromocytoma and paraganglioma.

Objective: To compare the diagnostic performance of [Ga]DOTATATE PET/CT, [F]FDG PET/CT, MRI of the spine, and whole-body CT and MRI for the detection of pheochromocytoma/paraganglioma (PPGL)-related spinal bone metastases.

Materials And Methods: Between 2014 and 2020, PPGL participants with spinal bone metastases prospectively underwent [Ga]DOTATATE PET/CT, [F]FDG PET/CT, MRI of the cervical-thoracolumbar spine (MRI), contrast-enhanced MRI of the neck and thoraco-abdominopelvic regions (MRI), and contrast-enhanced CT of the neck and thoraco-abdominopelvic regions (CT). Per-patient and per-lesion detection rates were calculated.

Demonstration of a low loss, highly stable and re-useable edge coupler for high heralding efficiency and low g(2)(0) SOI correlated photon pair sources.

We report a stable, low loss method for coupling light from silicon-on-insulator (SOI) photonic chips into optical fibers. The technique is realized using an on-chip tapered waveguide and a cleaved small core optical fiber. The on-chip taper is monolithic and does not require a patterned cladding, thus simplifying the chip fabrication process.

The effects of genotype-by-environment interactions on body condition score across three winter supplemental feed environments in a composite beef cattle breed in Montana.

Cattle operations in the Northern Great Plains region of the United States face extreme cold weather conditions and require nutritional supplementation over the winter season in order for animals to maintain body condition. In cow-calf operations, body condition scores (BCS) measured at calving and breeding have been shown to be associated with several economically important health and fertility traits, so maintenance of BCS is both an animal welfare and economic concern. A low-to-medium heritability has been found for BCS when measured across various production stages, indicating a large environmental influence but sufficient genetic basis for selection.

Prevalence of lung cysts in adolescents and adults with a germline pathogenic/likely pathogenic variant: a report from the National Institutes of Health and International Pleuropulmonary Blastoma/ Registry.

Background: Pleuropulmonary blastoma (PPB), the hallmark tumour associated with -related tumour predisposition, is characterised by an age-related progression from a cystic lesion (type I) to a high-grade sarcoma with mixed cystic and solid features (type II) or purely solid lesion (type III). Not all cystic PPBs progress; type Ir (regressed), hypothesised to represent regressed or non-progressed type I PPB, is an air-filled, cystic lesion lacking a primitive sarcomatous component. This study aims to evaluate the prevalence of non-progressed lung cysts detected by CT scan in adolescents and adults with germline pathogenic/likely pathogenic (P/LP) variants.

A Web Application for Predicting Drug Combination Efficacy Using Monotherapy Data and IDACombo.

We recently reported a computational method (IDACombo) designed to predict the efficacy of cancer drug combinations using monotherapy response data and the assumptions of independent drug action. Given the strong agreement between IDACombo predictions and measured drug combination efficacy in vitro and in clinical trials, we believe IDACombo can be of immediate use to researchers who are working to develop novel drug combinations. While we previously released our method as an R package, we have now created an R Shiny application to allow researchers without programming experience to easily utilize this method.

Estimated scale of costs to remove PFAS from the environment at current emission rates.

This discussion article builds upon existing data to ask whether environmental remediation and treatment is an economically viable solution to manage global environmental stocks of per- and polyfluoroalkyl substances (PFAS) without extensive use restrictions. Their environmental persistence means that PFAS released into the environment will remain there until actively removed and destroyed. Thus, removing and destroying PFAS from the global environment at the same rate they are currently being added reflects a theoretical steady-state condition where global PFAS stocks remain constant.

Is removal and destruction of perfluoroalkyl and polyfluoroalkyl substances from wastewater effluent affordable?

Several jurisdictions are currently evaluating regulatory standards for perfluoroalkyl and polyfluoroalkyl substances (PFAS) in municipal water resource recovery facility (WRRF) effluent. Effective and responsible implementation of PFAS effluent limits should consider the costs and capabilities of currently available technologies, because the costs of meeting WRRF PFAS limits could disproportionally fall to ratepayers. Cost curves were developed for currently available PFAS separation and destruction options, assuming effluent treatment targets near current analytical detection limits.

Dual carbon sequestration with photosynthetic living materials.

Natural ecosystems offer efficient pathways for carbon sequestration, serving as a resilient approach to remove CO from the atmosphere with minimal environmental impact. However, the control of living systems outside of their native environments is often challenging. Here, we engineered a photosynthetic living material for dual CO sequestration by immobilizing photosynthetic microorganisms within a printable polymeric network.
