OGG1 and MUTYH repair activities promote telomeric 8-oxoguanine induced senescence in human fibroblasts.

Telomeres are hypersensitive to the formation of the common oxidative lesion 8-oxoguanine (8oxoG), which impacts telomere stability and function. OGG1 and MUTYH glycosylases initiate base excision repair (BER) to remove 8oxoG or prevent mutation. Here, we show OGG1 loss or inhibition, or MUTYH loss, partially rescues telomeric 8oxoG-induced premature senescence and associated proinflammatory responses, while loss of both glycosylases causes a near complete rescue in human fibroblasts.

Refractory fungal infection: Three case reports highlighting good practice.

Refractory invasive fungal disease is a significant clinical problem, with high morbidity, mortality and costs. The complex causes of refractory infection include breakthrough infection due to antifungal resistance (both innate and acquired), suboptimal therapy and impaired immune responses in critically ill or immunocompromised patients. This case series details three reports on the identification and management of refractory fungal infections, two cases of azole resistance and one case of resistant candidiasis, highlighting the importance of accurate diagnosis, monitoring, implementation of biomarkers (serological markers, PCR), antifungal susceptibility testing and antifungal stewardship to optimise management and minimise risks of emergence of drug resistance.

A service evaluation of the implementation of a novel digital intervention for hypertension self-monitoring and management system in primary care (SHIP): protocol for a mixed methods study.

Background: Hypertension is a key risk factor for death and disability, and blood pressure reduction is associated with significant reductions in cardiovascular risk. Large trials have shown that interventions including self-monitoring of blood pressure can reduce blood pressure but real-world data from wider implementation are lacking.

Aim: The self-monitoring and management service evaluation in primary care (SHIP) study will evaluate a novel digital intervention for hypertension management and medication titration platform ("Hypertension-Plus") that is currently undergoing initial implementation into primary care in several parts of the UK.

Chemogenetic engagement of different GPCR signaling pathways segregates the orexigenic activity from the control of whole-body glucose metabolism by AGRP neurons.

Objective: The control of energy balance involves neural circuits in the central nervous system, including AGRP neurons in the arcuate nucleus of the hypothalamus (ARC). AGRP neurons are crucial for energy balance and their increased activity during fasting is critical to promote feeding behavior. The activity of these neurons is influenced by multiple signals including those acting on G-protein coupled receptors (GPCR) activating different intracellular signaling pathways.

Distortions to Passage of Time Judgements (POTJ) due to virtual threat are predicted by autonomic activation.

Humans' sense of the passage of time is subjective and determined by psychophysiological responses to the environment. The passing of time has been perceived to significantly slow in stressful situations, such as accidents or virtual threats. The current study will explore distortions in the perception of passage of time when threat is simulated using virtual reality (VR).

Modulating the immunodominance hierarchy of immunoglobulin germline-encoded structural motifs targeting the influenza hemagglutinin stem.

Antibodies targeting epitopes through germline-encoded motifs can be found in different individuals. While these public antibodies are often beneficial, they also pose hurdles for subdominant antibodies to emerge. Here, we use transgenic mice that reproduce the human IGHV1-6901 germline-encoded antibody response to the conserved stem epitope on group 1 hemagglutinin (HA) of influenza A virus to show that this germline-endowed response can be overridden by a subdominant yet cross-group reactive public antibody response.

Peer Emotion in Collaborative Simulation Among Nursing Students.

Background: The emotional experiences of nursing students are linked to learning outcomes. Peer learning is a key component of nursing education and simulation. However, little is known about the emotions of students in the context of peer learning.

A supported primary health pathway for mild traumatic brain injury quality improvement report.

Introduction Best-practice guidelines recommend that patients are followed-up to check if they have recovered following a mild traumatic brain injury (mTBI) and to refer to concussion services, if needed. However, in New Zealand, rates of follow-up are low and access to concussion services can be delayed. Aim We aimed to improve rates of follow-up and access to concussion services for mTBI patients aged ≥8 years by the implementation of a supported health pathway and test its success.

A conversation analytical study of call openings in Emergency Medical Service calls where the patient is at imminent risk of out-of-hospital cardiac arrest.

Background: The Chain of Survival identifies the importance of early recognition of patients who are at imminent risk of out-of-hospital cardiac arrest. This research investigated the interaction between callers and call-takers during calls to the Emergency Medical Service; it specifically focussed on patients who were alive at the initiation of the EMS call, but who subsequently deteriorated into out-of-hospital cardiac arrest during the prehospital phase of care (i.e.

Traumatic bleeding and mortality in mice are intensified by iron deficiency anemia and can be rescued with tranexamic acid.

Background: Clinical evidence suggests that anemia exacerbates traumatic bleeding and worsens outcomes.

Objectives: To study the influence of iron deficiency anemia on traumatic bleeding, coagulopathy, and mortality.

Methods: C57BL/6J mice received an iron-deficient diet (8 weeks; ±1 mg intraperitoneal iron dextran 2 weeks before trauma).

Comparison of initial adenosine dose conversion rate for supraventricular tachycardia in the emergency department.

Objective: To evaluate the rate of supraventricular tachycardia (SVT) termination between 6 mg and 12 mg initial adenosine doses.

Methods: This multi-center, retrospective cohort study evaluated patients presenting to the emergency department (ED) from January 1, 2020 to June 30, 2022 in SVT and received adenosine. The primary objective of the study is to compare the rate of SVT termination between adenosine 6 mg and 12 mg as documented on a formal electrocardiogram.

Weight stigma and binge eating related to poorer perceptions of healthcare provider interaction quality in a community-based sample.

Background: Weight stigma refers to the social rejection, discrimination, and ideological devaluation of individuals because of body size and is a direct result of weight bias and anti-fat attitudes. Individuals with higher weight may be less likely to seek healthcare due to weight stigma, and if or when they do present for care, medical providers with weight bias may fail to provide high quality care. Little, however, is known about the intersectionality of weight stigma and perceptions of healthcare interactions as experienced by individuals who also binge eat.

scRNA-seq identifies unique macrophage population in murine model of ozone induced asthma exacerbation.

Ozone (O ) inhalation triggers asthmatic airway hyperresponsiveness (AHR), but the mechanisms by which this occurs are unknown. Previously, we developed a murine model of dust mite, ragweed, and (DRA)-induced allergic lung inflammation followed by O exposure for mechanistic investigation. The present study used single cell RNA-sequencing for unbiased profiling of immune cells within the lungs of mice exposed to DRA, O , or DRA+O , to identify the components of the immune cell niche that contribute to AHR.

Qualitative exploration of uterine cancer care for lesbian, gay, bisexual, trans and queer (LGBTQ+) patients in the UK: shifting from equality to equity.

Objective: Patients identifying as lesbian, gay, bisexual, transgender and/or queer/questioning (LGBTQ+) report significant disparities in cancer care and are disproportionally affected by a cancer diagnosis on a number of health-related indicators. This study aimed to explore uterine cancer (UC) care from the perspectives of LGBTQ+ patients and stakeholders, to identify this population's care needs, which have been underprioritised thus far.

Methods And Analysis: Qualitative interview data were collected from three cohorts of participants: LGBTQ+ UC patients, partners of UC patients and stakeholders who provide advocacy and/or support within the UC care pathway, including healthcare professionals (HCPs).

The use of a pre-hospital questionnaire expedited the acute management of patients with ischemic stroke in a comprehensive stroke center.

Background: Delays in intravenous thrombolysis (IVT) treatment for acute ischemic stroke decrease the benefit of treatment. Difficulties determining a patient's clinical eligibility for IVT is a frequent cause of treatment delays.

Objective: We aimed to assess the effectiveness of the "PROVIDENCE" datasheet, a pre- hospital assessment of contraindications for IVT use applied by emergency medical services personnel.

Reduced B/B sensitivity in velocity-selective inversion arterial spin labeling using adiabatic refocusing pulses.

Purpose: To mitigate the B/B sensitivity of velocity-selective inversion (VSI) pulse trains for velocity-selective arterial spin labeling (VSASL) by implementing adiabatic refocusing. This approach aims to achieve artifact-free VSI-based perfusion imaging through single-pair label-control subtractions, reducing the need for the currently required four-pair dynamic phase-cycling (DPC) technique when using a velocity-insensitive control.

Methods: We introduce a Fourier-transform VSI (FT-VSI) train that incorporates sinc-modulated hard excitation pulses with MLEV-8-modulated adiabatic hyperbolic secant refocusing pairs.
