"Are we genuinely going to have our voices heard?" The experience of co-producing a blended intervention to prevent relapse in obsessive-compulsive disorder: a qualitative study on the perspectives of experts by lived experience.

Introduction: Co-production involves researchers, practitioners and people with lived experience working in a collaborative manner, with shared power. The potential benefits of co-production are well documented. However, there is little research describing the experience of having been involved in co-production from the perspective of Experts By Lived Experience (EBLE).

In vivo assessment of a modification of a domiciliary ventilator which reduces oxygen consumption in mechanically ventilated patients.

There are instances where hospitals may experience a relative shortage of oxygen, for example, future pandemics, natural disasters or wartime. We developed a modification to a domiciliary ventilator that captures oxygen normally vented during expiration into the atmosphere, delivering it to the patient. The modification significantly increases PaO in mechanically ventilated patients at their baseline FiO and baseline FiO +1, +2 and +3 L/min compared to no modification.

Forces to Be Reckoned with: Countervailing Powers and Physician Emotional Distress during COVID-19.

The "countervailing powers" framework conceptualizes health care as an arena for power contests among key stakeholders, drawing attention to the moves, countermoves, and alliances that have challenged physicians' dominance since the 1970s. Here, we focus on one of the lesser known micro-level consequences of such forces for physicians: emotional distress. We draw on 145 interviews with frontline physicians across four U.

Evaluation of Antibiotic Use for Dental-Related Infections in Dental Clinics Associated With an Academic Safety Net Institution.

This retrospective study found lower antibiotic prescribing rates by outpatient dentists than previous literature, but with deviations from guideline recommendations in antibiotic indications and durations of treatment for oral pain and swelling. These findings will guide future stewardship interventions to promote guideline-directed therapy plans.

Assessing AF2's ability to predict structural ensembles of proteins.

Recent breakthroughs in protein structure prediction have enhanced the precision and speed at which protein configurations can be determined. Additionally, molecular dynamics (MD) simulations serve as a crucial tool for capturing the conformational space of proteins, providing valuable insights into their structural fluctuations. However, the scope of MD simulations is often limited by the accessible timescales and the computational resources available, posing challenges to comprehensively exploring protein behaviors.

Oxidative Rearomatization of Tetrahydroisoquinolines Promoted by Pyridine--oxide.

Isoquinolines are ubiquitous arenes found in many biologically useful molecules. While direct substitution at the heterocyclic ring is uncommon, reductive functionalization to form tetrahydroisoquinolines (THIQs) is straightforward. Herein, we describe a facile method for producing C4-functionalized isoquinolines from a readily available parent THIQ.

Predictors of Alcohol Use, Alcohol-Related Problems, and Substance Use Following Adolescent Metabolic and Bariatric Surgery.

Objective: To identify factors associated with incident alcohol consumption, hazardous drinking, alcohol-related problems, and substance use up to 8 years following metabolic and bariatric surgery (MBS) during adolescence.

Background: In this cohort, nearly half of those who underwent MBS as adolescents screened positive for alcohol use disorder, symptoms of alcohol-related harm, or alcohol-related problems within 8 years post-surgery. Moreover, persistent or heavy marijuana use following MBS during adolescence is higher than national data.

Oral versus intravenous antibiotic therapy for Staphylococcus aureus bacteremia or endocarditis: a systematic review and meta-analysis of randomized controlled trials.

Background: We conducted a systematic review of randomized controlled trials (RCTs) to generate more precise estimates of the efficacy and safety of oral versus intravenous antibiotic therapy for S. aureus bacteremia or endocarditis.

Methods: MEDLINE, EMBASE, the Cochrane Library, and Web of Science database were searched through February 21st, 2024.

MR-conditionality failure modes: a comparison across various spinal cord stimulators.

As spinal cord stimulation (SCS) becomes a staple of chronic pain management, the SCS industry must constantly evolve to ensure safety, convenience and enhanced efficacy. Beyond waveforms and size, MR-conditionality is a key differentiator sought out by physicians and patients when choosing SCS devices. Many common SCS complications, including lead migration, can affect the MR-conditionality.

Mosquito species identification accuracy of early deployed algorithms in IDX, A vector identification tool.

Mosquito-borne diseases continue to pose a great threat to global public health systems due to increased insecticide resistance and climate change. Accurate vector identification is crucial for effective control, yet it presents significant challenges. IDX - an automated computer vision-based device capable of capturing mosquito images and outputting mosquito species ID has been deployed globally resulting in algorithms currently capable of identifying 53 mosquito species.

Utilising accessible and reproducible neurological assessments in clinical studies: Insights from use of the Neurological Impairment Scale in the multi-centre COVID-CNS study.

Reproducible and standardised neurological assessment scales are important in quantifying research outcomes. These scales are often performed by non-neurologists and/or non-clinicians and must be robust, quantifiable, reproducible and comparable to a neurologist's assessment. COVID-CNS is a multi-centre study which utilised the Neurological Impairment Scale (NIS) as a core assessment tool in studying neurological outcomes following COVID-19 infection.

V-ToCs (Venom Toxin Clustering): A tool for the investigation of sequence and structure similarities in snake venom toxins.

Recently, there has been a major push toward the development of next-generation treatments against snakebite envenoming. However, unlike current antivenoms that rely on animal-derived polyclonal antibodies, most of these novel approaches are reliant on an in-depth understanding of the over 2000 known snake venom toxins. Indeed, by identifying similarities (i.

HFIP promoted carbo-lactonisation as a new route to functionalised lactones.

We have been able to induce a series of lactonisation reactions of unsaturated acids using a carbocationic intermediate formed . The transformation generates five and six membered lactone rings AND forms a new exocyclic C-C bond at the same time, thus removing the need for further derivatisation of typical lactonisation products (such as from iodo lactonisation). The reaction is operationally straightforward, does not employ any metals and utilises readily accessible alcohol and unsaturated acid substrates.

Engineering of pH-dependent antigen binding properties for toxin-targeting IgG1 antibodies using light-chain shuffling.

Immunoglobulin G (IgG) antibodies that bind their cognate antigen in a pH-dependent manner (acid-switched antibodies) can release their bound antigen for degradation in the acidic environment of endosomes, while the IgGs are rescued by the neonatal Fc receptor (FcRn). Thus, such IgGs can neutralize multiple antigens over time and therefore be used at lower doses than their non-pH-responsive counterparts. Here, we show that light-chain shuffling combined with phage display technology can be used to discover IgG1 antibodies with increased pH-dependent antigen binding properties, using the snake venom toxins, myotoxin II and α-cobratoxin, as examples.

Longitudinal change in ultrasound-derived rectus femoris cross-sectional area in COPD.

Background: Skeletal muscle dysfunction is common in COPD. Ultrasound-derived rectus femoris cross-sectional area (RFCSA) is a radiation free, non-invasive measure of muscle bulk that relates to quadriceps strength in people with COPD. However, there are limited longitudinal data for RFCSA, and it is not known whether longitudinal change in RFCSA reflects change in quadricep strength, exercise capacity, lower limb function or muscle mass.

CO Laser-labeling on Fresh Produce: Evaluating Postharvest Quality, Microbial Safety, and Economic Analysis.

Fresh produce is traditionally labeled with plastic price lookup (PLU) stickers that are attached to the produce surface using edible glue. However, both the stickers and glue are environmental contaminants, and the stickers can still easily detach from the produce surface during handling and disrupt traceability. An alternative method of labeling, the CO laser-labeling technology (LLT), has been gaining attention in recent years.
