A Novel Pneudraulic Actuation Method to Enhance Soft Robot Control.

Modern industrial and medical applications require soft actuators with practical actuation methods, capable of precision control and high-speed performance. Within the realm of medical robotics, precision and speed imply less complications and reduced operational times. Soft fluidic actuators (SFAs) are promising candidates to replace the current rigid endoscopes due to their mechanical compliance, which offers safer human-robot interaction.

Detecting early signs of deterioration and preventing hospitalizations in skilled nursing facilities using remote respiratory monitoring.

An increase in respiratory rate (RR) can be an early indicator of clinical deterioration, yet it remains an often-neglected vital sign. The most common way of measuring RR is by manually counting chest-wall movements, a time-consuming and error-prone process. Staffing and funding shortages, particularly in post-acute and long-term care, mean these RR measurements are often infrequent, potentially leading to missed diagnoses and preventable readmissions.

'You're out on a limb, on your own': Social care personal assistants' (PAs') reflections on working in the Covid-19 pandemic - implications for wider health and care services.

Context: In England, Personal Assistants (PAs) are part of an international trend towards state funded but client-hired or directly employed care workers. The Covid-19 pandemic highlighted and exacerbated pre-existing risks and advantages of this arrangement for both PAs and people with care and support needs.

Objectives: We aim to report PAs' reflections on their experiences of working since the pandemic started in 2020 and highlight the longer-term implications for health and care services.

The metabolic effects of intermittent versus continuous feeding in critically ill patients.

Intermittent (or bolus) feeding regimens in critically ill patients have been of increasing interest to clinicians and scientists. Changes in amino acid, fat and carbohydrate metabolites over time might yet deliver other benefits (e.g.

Associations Between Amyloid Burden, Hypoxemia, Sleep Architecture, and Cognition in Obstructive Sleep Apnea.

Background: Obstructive sleep apnea (OSA) is associated with an increased risk of amyloid-β (Aβ) burden, the hallmark of Alzheimer's disease, and cognitive decline.

Objective: To determine the differential impacts of hypoxemia and slow-wave sleep disruption on brain amyloid burden, and to explore the effects of hypoxemia, slow-wave sleep disruption, and amyloid burden on cognition in individuals with and without OSA.

Methods: Thirty-four individuals with confirmed OSA (mean±SD age 57.

"Knowing that I had HPV, I literally just shut down": A qualitative exploration of the psychosocial impact of human papillomavirus (HPV) in women living with mental health conditions.

Objective: Psychological distress after testing positive for human papillomavirus (HPV) at cervical cancer screening is well documented in the general population. However, little is known about the impact of an HPV-positive result on those with pre-existing mental health conditions, who may be at higher risk of experiencing clinically significant distress. This study explored the psychosocial impact of HPV in women with co-morbid mental health conditions, as well as their experience of cervical screening during the COVID-19 pandemic.

Scale-up of a novel vital signs alert device to improve maternity care in Sierra Leone: a mixed methods evaluation of adoption.

Background: The CRADLE (Community blood pressure monitoring in Rural Africa: Detection of underLying pre-Eclampsia) Vital Signs Alert device-designed specifically to improve maternity care in low resource settings-had varying impact when trialled in different countries. To better understand the contextual factors that may contribute to this variation, this study retrospectively evaluated the adoption of CRADLE, during scale-up in Sierra Leone.

Methods: This was a mixed methods study.

The faecal microbiota is distinct in HLA-B27+ ankylosing spondylitis patients versus HLA-B27+ healthy controls.

Objectives: Spondyloarthritis (SpA) results from the interplay between genetic and environmental factors. An emerging modifiable factor is the human intestinal microbiota, which multiple studies in children and adults have shown to be abnormal in SpA patients, including enthesitis related arthritis and ankylosing spondylitis (AS). However, HLA-B27 itself appears to impact the contents of the microbiota and is more common in SpA patients versus controls, thus serving as a confounding factor in most comparative studies.

Adenoid ameloblastoma harbors beta-catenin mutations.

Adenoid ameloblastoma is a very rare benign epithelial odontogenic tumor characterized microscopically by epithelium resembling conventional ameloblastoma, with additional duct-like structures, epithelial whorls, and cribriform architecture. Dentinoid deposits, clusters of clear cells, and ghost-cell keratinization may also be present. These tumors do not harbor BRAF or KRAS mutations and their molecular basis appears distinct from conventional ameloblastoma but remains unknown.

Examining the relationship between autistic spectrum disorder characteristics and structural brain differences seen in anorexia nervosa.

Cortical differences have been reported in Anorexia Nervosa (AN) compared with healthy controls (HC); however, it is unclear if Autism Spectrum Disorder (ASD) characteristics are related to these cortical differences. The aim of this study was to examine if structural measures were correlated to ASD traits in AN. In total 184 female participants participated in the study; 57 acutely underweight AN participants (AAN), 59 weight-restored participants (WR) and 68 HC.

Relevance of sleep and associated structural changes in GBA1 mouse to human rapid eye movement behavior disorder.

Rapid eye movement (REM) sleep behaviour disorder (RBD) is a REM parasomnia that often predicts the later occurrence of alpha-synucleinopathies. Variants in the gene encoding for the lysosomal enzyme glucocerebrosidase, GBA, strongly increase the risk of RBD. In a GBA1-mouse model recently shown to mimic prodromal stages of α-synucleinopathy, we now demonstrate striking REM and NREM electroencephalographic sleep abnormalities accompanied by distinct structural changes in the more widespread sleep neurocircuitry.

Restricted truncal sagittal movements of rapid eye movement behaviour disorder.

Unlike sleep-walkers, patients with rapid-eye-movement-behaviour disorder (RBD) rarely leave the bed during the re-enactment of their dreams. RBD movements may be independent of spatial co-ordinates of the 'outside-world', and instead rely on (allocentric) brain-generated virtual space-maps, as evident by patients' limited truncal/axial movements. To confirm this, a semiology analysis of video-polysomnography records of 38 RBD patients was undertaken and paradoxically restricted truncal/thoraco-lumbar movements during complex dream re-enactments demonstrated.

Prevalence and utility of overnight pulse oximetry as a screening tool for obstructive sleep apnoea in newly diagnosed idiopathic intracranial hypertension.

Background: Idiopathic intracranial hypertension (IIH) is a condition of raised intracranial pressure (ICP). Obstructive sleep apnoea (OSA) has been shown to cause episodic rises in ICP and is frequently reported in patients with IIH. The aim of this study is to identify the prevalence of OSA in a cohort of IIH patients.

Environmental effects of stratospheric ozone depletion, UV radiation, and interactions with climate change: UNEP Environmental Effects Assessment Panel, Update 2021.

The Environmental Effects Assessment Panel of the Montreal Protocol under the United Nations Environment Programme evaluates effects on the environment and human health that arise from changes in the stratospheric ozone layer and concomitant variations in ultraviolet (UV) radiation at the Earth's surface. The current update is based on scientific advances that have accumulated since our last assessment (Photochem and Photobiol Sci 20(1):1-67, 2021). We also discuss how climate change affects stratospheric ozone depletion and ultraviolet radiation, and how stratospheric ozone depletion affects climate change.

Long-term outcome of vagus nerve stimulation for drug-resistant epilepsy using continuous assessment, with a note on mortality.

Purpose: To examine the outcome of vagus nerve stimulation (VNS) for drug-resistant epilepsy using data from a National Health Service VNS clinic.

Methods: Clinical records of patients implanted with VNS for epilepsy between1995 and 2010 were examined. Patients were selected for study who had at least one year of therapeutic stimulation (minimum 1 mA stimulator current) and follow-up by our service with analysable electronic records, providing continuous assessment of seizure control during available follow-up.

Testing positive for Human Papillomavirus (HPV) at primary HPV cervical screening: A qualitative exploration of women's information needs and preferences for communication of results.

Human Papillomavirus (HPV) primary cervical screening was implemented across England during 2019, where cervical cell samples are first tested for HPV and cytology is used to triage HPV-positive results. Around 8.5% of women who attend test HPV-positive with normal cytology (HPV+/normal).

Urinary incontinence and use of incontinence surgery after radical prostatectomy: a national study using patient-reported outcomes.

Objectives: To investigate whether patient-reported urinary incontinence (UI) and bother scores after radical prostatectomy (RP) result in subsequent intervention with UI surgery.

Patients And Methods: Men diagnosed with prostate cancer in the English National Health Service between April 2014 and January 2016 were identified. Administrative data were used to identify men who had undergone a RP and those who subsequently underwent a UI procedure.

3D MRI of the Hand and Wrist: Technical Considerations and Clinical Applications.

In the last few years, major developments have been observed in the field of magnetic resonance imaging (MRI). Advances in both scanner hardware and software technologies have witnessed great leaps, enhancing the diagnostic quality and, therefore, the value of MRI. In musculoskeletal radiology, three-dimensional (3D) MRI has become an integral component of the diagnostic pathway at our institutions.

Effect of intermittent or continuous feeding and amino acid concentration on urea-to-creatinine ratio in critical illness.

Background: We sought to determine whether peaks in essential amino acid (EAA) concentration associated with intermittent feeding may provide anabolic advantages when compared with continuous feeding regimens in critical care.

Methods: We performed a secondary analysis of data from a multicenter trial of UK intensive care patients randomly assigned to intermittent or continuous feeding. A linear mixed-effects model was developed to assess differences in urea-creatinine ratio (raised values of which can be a marker of muscle wasting) between arms.
