To describe the real-world clinical impact of a commercially available plasma cell-free DNA metagenomic next-generation sequencing assay, the Karius test (KT).

We retrospectively evaluated the clinical impact of KT by clinical panel adjudication. Descriptive statistics were used to study associations of diagnostic indications, host characteristics, and KT-generated microbiologic patterns with the clinical impact of KT. Multivariable logistic regression modeling was used to further characterize predictors of higher positive clinical impact.

We evaluated 1000 unique clinical cases of KT from 941 patients between January 1, 2017–August 31, 2023. The cohort included adult (70%) and pediatric (30%) patients. The overall clinical impact of KT was positive in 16%, negative in 2%, and no clinical impact in 82% of the cases. Among adult patients, multivariable logistic regression modeling showed that culture-negative endocarditis (OR 2.3; 95% CI, 1.11–4.53; P .022) and concern for fastidious/zoonotic/vector-borne pathogens (OR 2.1; 95% CI, 1.11–3.76; P .019) were associated with positive clinical impact of KT. Host immunocompromised status was not reliably associated with a positive clinical impact of KT (OR 1.03; 95% CI, 0.83–1.29; P .7806). No significant predictors of KT clinical impact were found in pediatric patients. Microbiologic result pattern was also a significant predictor of impact.

Our study highlights that despite the positive clinical impact of KT in select situations, most testing results had no clinical impact. We also confirm diagnostic indications where KT may have the highest yield, thereby generating tools for diagnostic stewardship.

Nasogastric tube (NGT) feeding against a patient's consent is an intervention that clinicians working in specialist mental health in-patient units may need to implement from time to time. Little research has explored clinician, patient and carer perspectives on good practice.

To use qualitative data from people with lived experience (PWLE), parents/carers and clinicians, to identify components of best practice when this intervention is required.

PWLE and parents/carers were recruited via BEAT UK's eating disorder charity. Clinicians were recruited via a post on The British Eating Disorders Society's research page. Semi-structured interviews were administered, transcribed and thematically analysed.

Thirty-six interviews took place and overlapping themes were identified. Participants spoke in relation to three themes: first, the significance of individualised care; second, the importance of communication; third, the impact of staff relationships. Sub-themes were identified and explored.

Good care evolved around positive staff relationships and individualised care planning rather than standard processes. The centrality of trust as an important mediator of outcome was identified, and this should be acknowledged in any service that delivers this intervention.

Nasogastric tube feeding under physical restraint is an intervention that clinicians working in specialist mental health in-patient units may need to implement.

To examine the impact of this intervention on people with lived experience, carers and staff.

People with lived experience and parents and/or carers were recruited via UK eating disorder charity Beat. Clinicians were recruited via the British Eating Disorders Society's research forum. Qualitative semi-structured interviews were conducted and transcribed, and the results were thematically analysed.

Thirty-six participants took part, and overlapping themes were identified. All participants spoke in relation to four themes: (a) the short-term impact on the patient; (b) the impact on those around the patient; (c) the long-term impact; and (d) the positive impact. Subthemes were identified and explored.

This lifesaving intervention can also negatively affect patients, parents and carers, peers and staff. Further research is needed to understand how interactions and environmental modifications can mitigate the negative impacts.

To identify the clinical characteristics of patients receiving nasogastric tube (NGT) feeding under physical restraint. Clinicians participated via professional networks and subsequent telephone contact. In addition to completing a survey, participants were invited to submit up to ten case studies.

The survey response rate from in-patient units was 100% and 143 case studies were submitted. An estimated 622 patients received NGT feeding under restraint in England in 2020–2021. The most common diagnosis was anorexia nervosa (68.5–75.7%), with depression, anxiety and autism spectrum disorder the most frequent comorbidities. Patients receiving the intervention ranged from 11 to 60 years in age (mean 19.02 years). There was wide variation in duration of use, from once to daily for 312 weeks (mode 1 week; mean 29.1 weeks, s.d. = 50.8 weeks).

NGT feeding under restraint is not uncommon in England, with variation in implementation. Further research is needed to understand how the high comorbidity and complexity contribute to initiation and termination of the intervention.

Clinicians working in mental health in-patient settings may have to use nasogastric tube feeding under physical restraint to reverse the life-threatening consequences of malnutrition when this is driven by a psychiatric condition such as a restrictive eating disorder.

To understand the decision-making process when nasogastric tube feeding under restraint is initiated in mental health in-patient settings.

People with lived experience of nasogastric tube feeding under restraint and parents/carers were recruited via the website of the UK's eating disorder charity BEAT. Eating disorder clinicians were recruited via an online post by the British Eating Disorders Society. Semi-structured interviews were administered to all participants.

Themes overlapped between the participant groups and were integrated in the final analysis. Two main themes were generated: first, ‘quick decisions’, with the subthemes of ‘medical risk’, ‘impact of not eating’ and ‘limited discussions’; second, ‘slow decisions’, with subthemes of ‘threats’, ‘discussions with patient’, ‘not giving up’ and ‘advanced directives’. Benefits and harms of both quick and slow decisions were identified.

This research offers a new perspective regarding how clinical teams can make best practice decisions regarding initiating nasogastric feeding under restraint. In-patient mental health teams facilitating this clinical intervention should consider discussing it with the patient at the beginning of their admission in anticipation of the need for emergency intervention and in full collaboration with the multidisciplinary team.

Veganism has increased in popularity in the past decade and, despite being a characteristic protected by law, is often viewed negatively by the general population. Little is known about the attitudes of healthcare professionals despite the potential influence on practice and eating disorder patient care. This is one of the first studies to investigate attitudes toward veganism within specialist eating disorder, general mental health and other professionals.

A one-way ANOVA indicated all professionals held positive views toward veganism. General mental health professionals held statistically more positive veganism attitudes than specialist eating disorder and other professionals.

As one of the first studies to suggest eating disorder professionals are not biased against veganism, it has important clinical practice implications, particularly when exploring motivations for adopting a vegan diet (health, weight loss, environmental or animal welfare concerns) in patients with eating disorders. Implications for further research are provided.

Bipolar disorder is a highly heritable polygenic disorder. Recent enrichment analyses suggest that there may be true risk variants for bipolar disorder in the expression quantitative trait loci (eQTL) in the brain.

We sought to assess the impact of eQTL variants on bipolar disorder risk by combining data from both bipolar disorder genome-wide association studies (GWAS) and brain eQTL.

To detect single nucleotide polymorphisms (SNPs) that influence expression levels of genes associated with bipolar disorder, we jointly analysed data from a bipolar disorder GWAS (7481 cases and 9250 controls) and a genome-wide brain (cortical) eQTL (193 healthy controls) using a Bayesian statistical method, with independent follow-up replications. The identified risk SNP was then further tested for association with hippocampal volume (n = 5775) and cognitive performance (n = 342) among healthy individuals.

Integrative analysis revealed a significant association between a brain eQTL rs6088662 on chromosome 20q11.22 and bipolar disorder (log Bayes factor = 5.48; bipolar disorder P = 5.85×10–5). Follow-up studies across multiple independent samples confirmed the association of the risk SNP (rs6088662) with gene expression and bipolar disorder susceptibility (P = 3.54×10–8). Further exploratory analysis revealed that rs6088662 is also associated with hippocampal volume and cognitive performance in healthy individuals.

Our findings suggest that 20q11.22 is likely a risk region for bipolar disorder; they also highlight the informative value of integrating functional annotation of genetic variants for gene expression in advancing our understanding of the biological basis underlying complex disorders, such as bipolar disorder.

Wearing of gloves reduces transmission of organisms by healthcare workers' hands but is not a substitute for hand hygiene. Results of previous studies have varied as to whether hand hygiene is worse when gloves are worn. Most studies have been small and used nonstandardized assessments of glove use and hand hygiene. We sought to observe whether gloves were worn when appropriate and whether hand hygiene compliance differed when gloves were worn.

Observational study.

Healthcare workers in 56 medical or care of the elderly wards and intensive care units in 15 hospitals across England and Wales.

We observed hand hygiene and glove usage (7,578 moments for hand hygiene) during 249 one-hour sessions. Observers also recorded whether gloves were or were not worn for individual contacts.

Gloves were used in 1,983 (26.2%) of the 7,578 moments for hand hygiene and in 551 (16.7%) of 3,292 low-risk contacts; gloves were not used in 141 (21.1%) of 669 high-risk contacts. The rate of hand hygiene compliance with glove use was 41.4% (415 of 1,002 moments), and the rate without glove use was 50.0% (1,344 of 2,686 moments). After adjusting for ward, healthcare worker type, contact risk level, and whether the hand hygiene opportunity occurred before or after a patient contact, glove use was strongly associated with lower levels of hand hygiene (adjusted odds ratio, 0.65 [95% confidence interval, 0.54-0.79]; P<.0001).

The rate of glove usage is lower than previously reported. Gloves are often worn when not indicated and vice versa. The rate of compliance with hand hygiene was significantly lower when gloves were worn. Hand hygiene campaigns should consider placing greater emphasis on the World Health Organization indications for gloving and associated hand hygiene.
