Video training of nursing home healthcare workers in palliative care.

Objectives: The provision of palliative care in nursing homes (NHs) is of paramount importance, a realism underscored by the frailty and medical complexity of the residents. However, palliative care (PC) education tends to be resource-intensive both for educators and healthcare workers (HCWs). The aim of this study was to investigate how PowerFacts, a video animation series that taught basic PC to NH HCWs in Singapore impacted their knowledge, attitudes and confidence.

Medical Nutrition Therapy for Chronic Kidney Disease: Low Access and Utilization.

CKD affects approximately half of US adults aged 65 years and older and accounts for almost 1 out of every 4 dollars of total Medicare fee-for-service spending. Efforts to prevent or slow CKD progression are urgently needed to reduce the incidence of kidney failure and reduce health care expenditures. Current CKD care guidelines recommend medical nutrition therapy (MNT), a personalized, evidence-based application of the Nutrition Care Process (assessment, intervention, diagnosis, and monitoring and evaluation) provided by registered dietitian nutritionists (RDNs) to help slow CKD progression, improve quality of life, and delay kidney failure.

Attrition from longitudinal ageing studies and performance across domains of cognitive functioning: an individual participant data meta-analysis.

Objectives: This paper examined the magnitude of differences in performance across domains of cognitive functioning between participants who attrited from studies and those who did not, using data from longitudinal ageing studies where multiple cognitive tests were administered.

Design: Individual participant data meta-analysis.

Participants: Data are from 10 epidemiological longitudinal studies on ageing (total n=209 518) from several Western countries (UK, USA, Mexico, etc).

Serum uric acid did not affect embryonic and pregnancy outcomes in women without PCOS during IVF procedures.

Objectives: Serum uric acid (UA) levels are associated with many systemic diseases. A previous study confirmed the association between high serum uric acid levels and poor prognosis of fertilization (IVF) treatment in polycystic ovary syndrome (PCOS) patients. This study aimed to explore the correlation between serum uric acid levels and reproductive outcomes in patients without PCOS.

Improving bacteria identification from digital melt assay via oligonucleotide-based temperature calibration.

Background: Bacterial infections, especially polymicrobial infections, remain a threat to global health and require advances in diagnostic technologies for timely and accurate identification of all causative species. Digital melt - microfluidic chip-based digital PCR combined with high resolution melt (HRM) - is an emerging method for identification and quantification of polymicrobial bacterial infections. Despite advances in recent years, existing digital melt instrumentation often delivers nonuniform temperatures across digital chips, resulting in nonuniform digital melt curves for individual bacterial species.

Opposing roles of organic salts on mini-protein structure.

We investigated the effects of 1-ethyl-3-methylimidazolium chloride ([EMIM][Cl]) and choline chloride ([Chol][Cl]) on the local environment and conformational landscapes of Trp-cage and Trpzip4 mini-proteins using experimental and computational approaches. Fluorescence experiments and computational simulations revealed distinct behaviors of the mini-proteins in the presence of these organic salts. [EMIM][Cl] showed a strong interaction with Trp-cage, leading to fluorescence quenching and destabilization of its native structural interactions.

Computed tomography-based gastric volumetry for morbid obesity to assess weight loss and fatty liver change.

Background/purpose: Laparoscopic sleeve gastrectomy (LSG) is an effective treatment for patients with morbid obesity, but the optimal gastric volume (GV) for resection remains unclear. Accordingly, we aimed to determine the optimal percentage of excised stomach that could engender significant weight loss and improve fatty liver.

Methods: This prospective study included 63 patients.

High incidence of cerebrovascular lesions on magnetic resonance imaging in pediatric COVID-19 during omicron outbreak - A retrospective case series.

Background: The incidence of pediatric hospitalizations has significantly increased since the spread of the omicron variant of COVID-19. Changes of characteristics in respiratory and neurological symptoms have been reported. We performed a retrospective, cross-sectional study to characterize the MRI change in children with an emphasis on the change of cerebral vasculatures.

Paternal Preconceptional Alcohol Use Disorder With the Offspring's Mortality Risk.

Introduction: Paternal preconceptional alcohol use may contribute to early pregnancy loss. However, the link between paternal preconceptional alcohol use disorder and long-term offspring's mortality risk remains unclear. This study examined the association of paternal preconceptional alcohol use disorder and recency of diagnosis with offspring's mortality and further stratified the mortality after the first year of birth by age.

Optimizing theatre utilization for abscess drainage: going beyond priority categories.

Background: Day-only emergency surgery for abscess drainage is poorly implemented in Australia. This study assessed the feasibility, outcomes, cost, and impact of an acute day-only surgery (ADOS) program.

Method: A retrospective pre-post implementation study of patients requiring abscess drainage in theatre was performed.

Adult Outcome After Partial Androgen Insensitivity Syndrome: Diagnosed and Assigned Female in Infancy.

This patient, now in her 40s, was evaluated because of genital ambiguity and diagnosed with pAIS in infancy based upon elevated testosterone and gonadotropin levels and significantly reduced binding affinity of the androgen receptor. Such reduced binding is consistent with a structural abnormality of the receptor protein precluding expected activity of the androgen receptor. Based on this information and counseling, her parents chose a female sex assignment.

Protocol for a single-arm, pilot trial of creatine monohydrate supplementation in patients with Alzheimer's disease.

Background: Impaired brain bioenergetics is a pathological hallmark of Alzheimer's disease (AD) and is a compelling target for AD treatment. Patients with AD exhibit dysfunction in the brain creatine (Cr) system, which is integral in maintaining bioenergetic flux. Recent studies in AD mouse models suggest Cr supplementation improves brain mitochondrial function and may be protective of AD peptide pathology and cognition.

Expression patterns of Piezo1 in the developing mouse forebrain.

Malformation during cortical development can disrupt the balance of excitatory and inhibitory neural circuits, contributing to various psychiatric and developmental disorders. One of the critical factors of cortical neural networks is the fine regulation of neurogenesis through mechanical cues, such as shear stress and substrate stiffness. Piezo1, a mechanically-activated channel, serves as a transducer for these mechanical cues, regulating embryogenesis.

Towards high performance and durable soft tactile actuators.

Soft actuators are gaining significant attention due to their ability to provide realistic tactile sensations in various applications. However, their soft nature makes them vulnerable to damage from external factors, limiting actuation stability and device lifespan. The susceptibility to damage becomes higher with these actuators often in direct contact with their surroundings to generate tactile feedback.

Robotic hiatal hernia repair without mesh.

Background: Newer minimally invasive techniques have supplanted laparotomy and thoracotomy for management of hiatal hernias. Limited data exists on outcomes after robotic hiatal hernia repair without mesh despite the increasing popularity of this approach. We report our high-volume experience with durable robotic hiatal hernia repair with gastric fundoplication without mesh.

Outcomes Following Pelvic Exenteration for Locally Recurrent Rectal Cancer With and Without En Bloc Sacrectomy.

Background: Extended radical resection is often the only chance of cure for locally recurrent rectal cancer. Recurrence in the posterior compartment often necessitates en bloc sacrectomy as part of pelvic exenteration to obtain clear resection margins and provide survival benefit.

Objective: To compare oncological outcomes, morbidity, and quality-of-life outcomes following pelvic exenteration with and without en bloc sacrectomy for recurrent rectal cancer.

Alternative translation initiation produces synaptic organizer proteoforms with distinct localization and functions.

While previous studies suggest that many mRNAs contain more than one translation initiation site (TIS), the biological significance of most alternative TISs and their corresponding protein isoforms (proteoforms) remains undetermined. Here we show that alternative translation initiation at a CUG and an AUG TIS in neuronal pentraxin receptor (NPR) mRNA produces two proteoforms, and their relative abundance is regulated by both neuronal activity as well as an adjacent RNA secondary structure. Downstream AUG initiation transforms the N-terminal transmembrane domain into a signal peptide, thereby converting NPR to a secreted factor sufficient to promote synaptic clustering of AMPA-type glutamate receptors.

Pore evolution mechanisms during directed energy deposition additive manufacturing.

Porosity in directed energy deposition (DED) deteriorates mechanical performances of components, limiting safety-critical applications. However, how pores arise and evolve in DED remains unclear. Here, we reveal pore evolution mechanisms during DED using in situ X-ray imaging and multi-physics modelling.

Associations between community green view index and fine particulate matter from Airboxes.

Urban greenery can help to improve air quality, reduce health risks and create healthy livable urban communities. This study aimed to explore the role of urban greenery in reducing air pollution at the community level in Tainan City, Taiwan, using air quality sensors and street-view imagery. We also collected the number of road trees around each air quality sensor site and identified the species that were best at absorbing PM.

STING signalling compensates for low tumour mutation burden to drive anti-tumour immunity.

Background: While mutation-derived neoantigens are well recognized in generating anti-tumour T cell response, increasing evidences highlight the complex association between tumour mutation burden (TMB) and tumour infiltrating lymphocytes (TILs). The exploration of non-TMB determinants of active immune response could improve the prognosis prediction and provide guidance for current immunotherapy.

Methods: The transcriptomic and whole exome sequence data in The Cancer Genome Atlas were used to examine the relationship between TMB and exhausted CD8+ T cells (Tex), as an indicator of tumour antigen-specific T cells across nine major cancer types.

Ductile Copolyesters Prepared Using Succinic Acid, 1,4-Butanediol, and Bis(2-hydroxyethyl) Terephthalate with Minimizing Generation of Tetrahydrofuran.

Poly(1,4-butylene succinate) (PBS) is a promising sustainable and biodegradable synthetic polyester. In this study, we synthesized PBS-based copolyesters by incorporating 5-20 mol% of -OCCHCO- and -OCHCHO- units through the polycondensation of succinic acid (SA) with 1,4-butanediol (BD) and bis(2-hydroxyethyl) terephthalate (BHET). Two different catalysts, HPO and the conventional catalyst (nBuO)Ti, were used comparatively in the synthesis process.
