Whilst 'brain fog' is mostly considered a biological problem little is understood about an individual's experience. This qualitative study explored women's experiences of brain fog focusing on those at the start (aged 18-25;  = 10) and end (aged 45-60;  = 10) of their reproductive journey. Descriptive thematic analysis described three themes: (i) 'daily disruptions' describing cognitive dysfunctions and the main triggers; (ii) 'the cycle of impact' with a focus on women's emotional experiences and how these can exacerbate brain fog; (iii) 'taking control' highlighting the use of self-care, physical prompts and Hormonal Replacement Therapy (HRT) to manage brain fog.

Introduction: Patients experience high symptom burden during critical care hospitalization and mechanical ventilation. Medications are of limited effectiveness and are associated with increased morbidity such as delirium and long-term cognitive and psychological impairments. Music-based interventions have been used for pain and anxiety management in critical care but remain understudied in terms of music selection and range of symptoms.

Background: Atrial fibrillation (AF) is associated with an increased risk of stroke, yet the limitations of conventional monitoring have restricted our understanding of AF burden risk thresholds. Predictive algorithms incorporating continuous AF burden measures may be useful for predicting stroke. This study evaluated the performance of temporal AF burden trends as predictors of stroke from a large cohort with insertable cardiac monitors.

Older adults who smoke are half as likely to make a quit attempt, but more likely to maintain abstinence using evidence-based treatments. Awareness of the increased risk of dementia among people who currently smoke may motivate cessation in this population, but messages have not been tested. 820 adults who smoke, ages 50-80, with no history of dementia completed an online survey examining one of three randomly assigned messages (Control N = 266, Fear N = 274, Hope N = 280) on motivation and intentions to quit.

Lymphomatous infiltration of the peripheral nervous system (PNS), termed neurolymphomatosis, represents a distinct extranodal non-Hodgkin lymphoma variant with dismal outcome. CD19-directed chimeric antigen receptor (CD19-CAR) T-cell therapy has emerged as a safe and effective treatment for B-cell lymphomas. We aimed to assess toxicity and efficacy of CD19-CAR T-cells in neurolymphomatosis.

Article Synopsis
  • Individuals with serious mental illness (SMI) exiting the criminal justice system struggle more with accessing mental health services compared to those without such a background, prompting the exploration of peer navigation interventions.
  • A qualitative study involving interviews and focus groups with peer navigators and those with SMI revealed that participants found peer navigation services to be both feasible and acceptable for helping with community reentry.
  • Key themes included the role of peers in overcoming care barriers, the positive impact of shared identities in reducing stigma, and essential skills for peer navigators, such as empathy and active listening, along with recommendations for program implementation.

Article Synopsis
  • Repeat expansions in the C9orf72 gene are a leading genetic cause of ALS and frontotemporal dementia, but understanding how this mutation causes neuron death is still unclear, complicating the search for effective therapies.
  • Researchers analyzed data from over 41,000 ALS and healthy samples to identify potential treatments, discovering that acamprosate, a drug used for other conditions, might be repurposed for C9orf72-related diseases.
  • Their findings demonstrated that acamprosate has neuroprotective properties in cell models and works similarly well as the current treatment, riluzole, showing the potential of using genomic data to find new drug applications.

Rab11 family interacting protein 4 (Rab11-FIP4) regulates endocytic trafficking. A possible role for Rab11-FIP4 in the regulation of lysosomal function has been proposed, but its precise function in the regulation of cellular homeostasis is unknown. By mRNA array and protein analysis, we found that Rab11-FIP4 is downregulated in the lysosomal storage disease cystinosis, which is caused by genetic defects in the lysosomal cystine transporter, cystinosin.

The chemical synthesis of -acyl indoles is hindered by the poor nucleophilicity of indolic nitrogen, necessitating the use of strongly basic reaction conditions that encumber elaboration of highly functionalized scaffolds. Herein, we describe the total chemoenzymatic synthesis of the bulbiferamide natural products by the biochemical activity reconstitution of a nonribosomal peptide synthetase assembly line-derived (NRPS-derived) thioesterase that neatly installs the macrocyclizing indolylamide. The enzyme represents a starting point for biocatalytic access to macrocyclic indolylamide peptides and natural products.

Background: The human gut microbiome develops rapidly during infancy, a key window of development coinciding with the maturation of the adaptive immune system. However, little is known about the microbiome growth dynamics over the first few months of life and whether there are any generalizable patterns across human populations. We performed metagenomic sequencing on stool samples ( = 94) from a cohort of infants ( = 15) at monthly intervals in the first 6 months of life, augmenting our dataset with seven published studies for a total of 4,441 metagenomes from 1,162 infants.

Adverse childhood experiences (ACEs) have been linked with attachment insecurity and psychopathology. However, some individuals remain securely attached and resilient following ACEs. Researchers have examined polymorphisms in the oxytocin receptor gene (OXTR), particularly rs53576, as a source of resilience, though examination of the biological mechanism by which rs53576 buffers the relation that would otherwise exist between ACEs and attachment insecurity is absent.

Background: Previous research has highlighted links between occupation and risk of COVID-19 transmission and suggests that occupational risk is influenced by covariates including socio-economic status, and deprivation. This study examined the perspectives of local authority teams of how changes in policy and advice, as set out in the UK government report 'Living with COVID,' affected COVID-19 transmission risk, response and resilience in workplace settings in Greater Manchester, an area that was disproportionately affected by the pandemic.

Methods: The project, which took place between August and November 2022, undertook a mixed methods approach to incorporate wide-ranging reflections of changes following the publication of 'Living with COVID'.

Article Synopsis
  • The study investigates the associated production of Higgs and W bosons, focusing on how the relative signs of the Higgs couplings to W and Z bosons impact the process.
  • Two specific searches were conducted using large amounts of collision data from the LHC to analyze different coupling scenarios: one for opposite-sign couplings and another for same-sign (standard model-like) couplings.
  • The results significantly exclude the opposite-sign coupling hypothesis and set a strict upper limit on the production rate of this process compared to standard model predictions.
