Purpose: We have established the SAIL MELD-B electronic cohort (e-cohort SMC) and the SAIL MELD-B children and Young adults e-cohort (SMYC) as a part of the Multidisciplinary Ecosystem to study Lifecourse Determinants and Prevention of Early-onset Burdensome Multimorbidity (MELD-B) project. Each cohort has been created to investigate and develop a deeper understanding of the lived experience of the 'burdensomeness' of multimorbidity by identifying new clusters of burdensomeness concepts, exploring early life risk factors of multimorbidity and modelling hypothetical prevention scenarios.

Participants: The SMC and SMYC are longitudinal e-cohorts created from routinely collected individual-level population-scale anonymised data sources available within the Secure Anonymised Information Linkage (SAIL) Databank.

The concept of 'resilience' is pervasive, permeating academic disciplines and political discourses. This paper considers (i) the construal of 'resilience' in the contexts of food insecurity and cost-of-living in governmental discourses in the United Kingdom (UK); (ii) to what extent the political representations are reflected in research funding calls of UK national funding bodies, thus showing possibility of shaping research agendas; and (iii) to what extent official uses of 'resilience' reflect lay understandings. We are combining a corpus-based discourse analysis of UK governmental discourses and research funding calls with a study of focus group discussions.

Major depressive disorder (MDD) often goes undiagnosed due to the absence of clear biomarkers. We sought to identify voice biomarkers for MDD and separate biomarkers indicative of MDD predisposition from biomarkers reflecting current depressive symptoms. Using a two-stage meta-analytic design to remove confounds, we tested the association between features representing vocal pitch and MDD in a multisite case-control cohort study of Chinese women with recurrent depression.

Structural violence - related to 'isms' like racism, sexism, and ableism - pertains to the ways in which social institutions harm certain groups. Such violence is critical to institutional indifference to the plight of ethnic minority people living with long-term health conditions. With only emergent literature on the lived experiences of ethnic minorities with Long Covid, we sought to investigate experiences around the interplay of illness and structural vulnerabilities.

Dysphagia lusoria is a rare condition characterized by swallowing difficulties due to vascular compression of the esophagus. While most commonly caused by an aberrant right subclavian artery (ARSA), other vascular anomalies can also lead to this condition. We present a unique case of dysphagia lusoria in a 20-year-old Ethiopian male, caused by a vertebral artery originating anomalously from the aortic arch.

Background: Multiple long-term conditions (MLTCs), living with two or more long-term conditions (LTCs), often termed multimorbidity, has a high and increasing prevalence globally with earlier age of onset in people living in deprived communities. A holistic understanding of the patient's perspective of the work associated with living with MLTCs is needed. This study aimed to synthesise qualitative evidence describing the experiences of people living with MLTCs (multimorbidity) and to develop a greater understanding of the effect on people's lives and ways in which living with MLTCs is 'burdensome' for people.

Early detection and management of cardiovascular diseases (CVDs) are crucial for patient survival and long-term health. CVD biomarkers such as cardiac Troponin-I (cTnI), N-terminal pro-brain natriuretic peptide (NT-proBNP), creatine kinase MB (CK-MB), Galectin-3 (Gal-3), etc are released into the circulation following heart muscle injury, ie, acute myocardial infarction (AMI). Biosensor technology including the use of nanoparticles can be designed to target specific biomarkers associated with CVD, enabling early detection and more rapid intervention to decrease morbidity and mortality.

Uncertainty of data, the degree to which data are inaccurate, imprecise, untrusted, and undetermined, is inherent in many contemporary database applications, and numerous research endeavours have been devoted to efficiently answer skyline queries over uncertain data. The literature discussed two different methods that could be used to handle the data uncertainty in which objects having continuous range values. The first method employs a probability-based approach, while the second assumes that the uncertain values are represented by their median values.

Optimising preconception health in women and men holds significant potential for improving pregnancy and offspring health outcomes. To create a picture of the state of preconception health in the UK, this study aimed to describe the prevalence of and changes in preconception health indicators reported in three British birth cohort studies: the 1970 British Birth Cohort Study (BCS70; born in 1970; N = 17,198), Next Steps (1989-1990; N = 15,770), and Millennium Cohort Study (MCS; 2000-2002; N = 19,517). The analysis focused on data obtained during participants' adolescence (16-17 years) and subsequent follow-ups at 25-26 years for BCS70 and Next Steps.

Patients with chronic liver disease (CLD) are prone to complications associated with impaired liver functioning. This coupled with iron-deficiency anaemia (IDA) can predispose them to multiple comorbidities. We present an interesting case of a 69-year-old woman with a background history of liver cirrhosis due to metabolic dysfunction-associated steatotic liver disease (MASLD) with frequent travels to Bangladesh, a southeast Asian country known for having high levels of manganese (Mn) in water for domestic use.

Acetaminophen is a common over-the-counter medication that recently gained substantial media attention regarding its use by pregnant individuals. In this clinical perspective, we discuss the strengths and limitations of the published literature on the effect of maternal acetaminophen use in pregnancy on the child's risk of developing attention-deficit and hyperactivity disorder (ADHD) and autistic spectrum disorder (ASD). Studies included were specifically selected on the basis of the quality and validity of ADHD or ASD outcome definitions.

The human gut microbiome is a dynamic and intricate ecosystem, composed of trillions of microorganisms that play a pivotal role in maintaining overall health and well-being. However, the gut microbiome is constantly exposed to various environmental factors, including the bile produced by the liver, which can significantly impact its composition and function. Bile acids, secreted by the liver and stored in the gallbladder, modulate the gut microbiome, influencing its composition and function.

Long Covid is the continuation or development of symptoms related to a SARSCoV2 infection. Those with Long Covid may face epistemic injustice, where they are unjustifiably viewed as unreliable evaluators of their own illness experiences. Media articles both reflect and influence perception and subsequently how people regard children and young people (CYP) with Long Covid, and may contribute to epistemic injustice.
