Evaluating methods for identifying and quantifying co-colonization using next-generation sequencing data.

Detection of multiple pneumococcal serotype carriage can enhance monitoring of pneumococcal vaccine impact, particularly among high-burden childhood populations. We assessed methods for identifying co-carriage of pneumococcal serotypes from whole-genome sequences. Twenty-four nasopharyngeal samples were collected during community carriage surveillance from healthy children in Blantyre, Malawi, which were then serotyped by microarray.

"I'm quite proud of how we've handled it": health professionals' experiences of returning additional findings from the 100,000 genomes project.

Participants in the 100,000 Genomes Project (100kGP) could consent to receive additional finding (AF) results, individual variants relating to genes associated with susceptibility to cancer and familial hypercholesterolemia (FH). In the study reported here, qualitative interviews were used to explore the experiences of National Health Service (NHS) professionals from across England who were tasked with returning over 80,000 "no AF" results and 700 positive AF results to 100kGP participants. Interviews were conducted with 45 professionals from a range of backgrounds, including Genetic Counsellors, Clinical Geneticists, FH Clinical Nurse Specialists and Clinical Scientists.

Exploring Health-Related Quality of Life (HRQOL) among patients with HIV-associated TB in Khayelitsha, South Africa.

Background: Health-related quality of life (HRQOL) is an important and frequently used patient-reported outcome in health research. However, little qualitative research exists in this field in South Africa. This study was set in Khayelitsha, one of the largest informal settlements in South Africa, where the burden of HIV and tuberculosis (TB) co-infection are amongst the highest in the world and significantly affect HRQOL.

Cardiomyopathies in 100,000 genomes project: interval evaluation improves diagnostic yield and informs strategies for ongoing gene discovery.

Background: Cardiomyopathies are clinically important conditions, with a strong genetic component. National genomic initiatives such as 100,000 Genome Project (100KGP) provide opportunity to study these rare conditions at scale beyond conventional research studies.

Methods: We present the clinical and molecular characteristics of the 100KGP cohort, comparing paediatric and adult probands with diverse cardiomyopathies.

Corrigendum: SARS-CoV-2 seroprevalence in pregnant women in Kilifi, Kenya from March 2020 to March 2022.

An international physician survey of current ablation practices in atrial fibrillation: An AIM-AF substudy.

Background: Practice guidelines recommend ablation (ABL) in atrial fibrillation (AF) for rhythm control. Guidance for antiarrhythmic drugs (AADs) post-ABL is limited.

Objective: The purpose of this study was to determine AAD and ABL practices in the United States and Europe.

Decoding Apelin: Its Role in Metabolic Programming, Fetal Growth, and Gestational Complications.

Placental insufficiency and gestational diabetes, which are both serious pregnancy complications, are linked to altered fetal growth, whether restricted or excessive, and result in metabolic dysfunction, hypoxic/oxidative injury, and adverse perinatal outcomes. Although much research has been carried out in this field, the underlying pathogenetic mechanisms have not as yet been fully elucidated. Particularly because of the role it plays in cardiovascular performance, glucose metabolism, inflammation, and oxidative stress, the adipokine apelin was recently shown to be a potential regulator of fetal growth and metabolic programming.

Molecular Testing of Environmental Samples as a Potential Source to Estimate Parasite Infection.

We discuss the potential usefulness of molecular testing of soil, dust, and water samples to detect medically important parasites, and where such testing could be used to supplement stool sampling in humans. A wide variety of parasites including protozoa and helminths, many of which are zoonotic, have an important infection reservoir in the environment. In some cases, this environmental period is essential for further parasite development.

Case Report: Ethanol ablation of the Marshall vein as the first step for left atrial tachycardia ablation.

Electroanatomic mapping guides complex atrial tachycardia ablations; however, challenges may emerge after pulmonary vein isolation. 3D mapping systems can reveal the mechanism of tachycardia and critical areas that need to be ablated. Sometimes, however, these areas may be located deep inside, to the extent that they cannot be successfully reached by endocardial ablation.

Evaluating the consistency of judgments derived through both in silico and expert application of the Cramer classification scheme.

The Cramer classification scheme has emerged as one of the most extensively-adopted predictive toxicology tools, owing in part to its employment for chemical categorisation within threshold of toxicological concern evaluation. The characteristics of several of its rules have contributed to inconsistencies with respect to degree of hazard attributed to common (particularly food-relevant) substances. This investigation examines these discrepancies, and their origins, raising awareness of such issues amongst users seeking to apply and/or adapt the rule-set.

Huntington's disease phenocopy syndromes revisited: a clinical comparison and next-generation sequencing exploration.

Background: Genetic testing for Huntington's disease (HD) was initially usually positive but more recently the negative rate has increased: patients with negative HD tests are described as having HD phenocopy syndromes (HDPC). This study examines their clinical characteristics and investigates the genetic causes of HDPC.

Methods: Clinical data from neurogenetics clinics and HDPC gene-panel data were analysed.

External Factors Modulating Pain and Pain-Related Functional Impairment in Cervical Dystonia.

Background: Little is known about factors modulating pain and pain-related functional impairment in isolated cervical dystonia (CD).

Objective: The aim was to assess the prevalence and interrelationship between pain-modulating factors and pain-related determinants of functional impairment and quality of life in CD.

Methods: We analyzed pain-aggravating and pain-relieving external factors, the degree of pain-related functional impact on routine activities, and the relationship between these and pain severity, using cross-sectional data collected using the Pain in Dystonia Scale (PIDS) from 85 participants with CD.

Differential temporal decline of cerebral oxytocin and μ-opioid receptor density during the aging process in mice.

Aging is often associated with changes in social, sexual, emotional and pain functioning, as well as with the increased prevalence of certain psychopathologies. However, the neurodevelopmental basis underpinning these age-related changes remains to be determined. Considering the key roles of oxytocin (OTR) and μ-opioid (MOPr) receptor systems in regulating social, sexual, pain, reward and emotional processing, it seems plausible that they are also implicated in age-related behavioural alterations.

Basal ganglia theta power indexes trait anxiety in people with Parkinson's disease.

Neuropsychiatric symptoms are common and disabling in Parkinson's disease (PD), with troublesome anxiety occurring in one-third of patients. Management of anxiety in PD is challenging, hampered by insufficient insight into underlying mechanisms, lack of objective anxiety measurements, and largely ineffective treatments. In this study, we assessed the intracranial neurophysiological correlates of anxiety in PD patients treated with deep brain stimulation (DBS) in the laboratory and at home.

Outcomes of twin pregnancies complicated by prelabor rupture of membranes before 26 weeks of gestation: systematic review and meta-analysis.

Objective: To investigate the rate of obstetric and perinatal outcomes of premature rupture of membranes (PROM) occurring before 26 weeks in twin pregnancies.

Data Source: Medline, Embase, Cinahl and Web of Science databases were searched electronically up to January 2024.

Study Eligibility Criteria: The selection criteria included both prospective and retrospective studies of twin pregnancies with PROM before 26 weeks of gestation.

Identifying AWaRe indicators for appropriate antibiotic use: a narrative review.

Introduction: Quality indicators (QIs) are widely used tools for antibiotic stewardship programmes. The Access, Watch, Reserve (AWaRe) system has been developed by the WHO to classify antibiotics based on their spectrum of activity and potential selection of antibiotic resistance. This review aimed to identify existing indicators for optimal antibiotic use to inform the development of future AWaRe QIs.
