The role of metabolites, nutrients, and toxins (MNTs) in sera at the end of pregnancy and of their association with offspring respiratory and allergic disorders is underexplored. Untargeted approaches detecting a variety of compounds, known and unknown, are limited. In this cohort study, we first aimed at discovering associations of MNTs in grandmaternal (F0) serum with asthma, immunoglobulin E, skin prick tests, exhaled nitric oxide, and lung function parameters in their parental (F1) offspring. Second, for replication, we tested the identified associations of MNTs with disorders in their grandchildren (F2-offspring) based on F2 cord serum. The statistical analyses were sex-stratified. Using liquid chromatography/high-resolution mass spectrometry in F0, we detected signals for 2286 negative-ion lipids, 59 positive-ion lipids, and 6331 polar MNTs. Nine MNTs (one unknown MNT) discovered in F0-F1 and replicated in F2 showed higher risks of respiratory/allergic outcomes. Twelve MNTs (four unknowns) constituted a potential protection in F1 and F2. We recognized MNTs not yet considered candidates for respiratory/allergic outcomes: a phthalate plasticizer, an antihistamine, a bile acid metabolite, tryptophan metabolites, a hemiterpenoid glycoside, triacylglycerols, hypoxanthine, and polyphenol syringic acid. The findings suggest that MNTs are aspirants for clinical trials to prevent adverse respiratory/allergic outcomes.

Aim: This study aimed to explore the impact of caring for an individual with neurogenic orthostatic hypotension (nOH). Methods: Informal caregivers of individuals with nOH and either Parkinson's disease, multiple system atrophy, pure autonomic failure or dementia with Lewy bodies completed semi-structured interviews. Data were analyzed using thematic analysis; the identified concepts were used to develop a conceptual model. Results: Twenty informal caregivers were interviewed. Analysis identified several areas of caregiver impact due to nOH including impact on their time, particularly a need to supervise the patient to prevent falls as well as a lack of freedom and negative physical, work and social impacts. Many reported negative emotional impacts, including worry, stress or fear about the patient falling, depression and frustration. The conceptual model shows the relationships between concepts. Conclusion: The results highlight the wide-ranging impact of nOH, and the specific impact of the fear of falls on informal caregivers' lives.

Aim: This study explores the burden of caring for an individual with neurogenic orthostatic hypotension (nOH) and an underlying neurodegenerative disease (Parkinson’s disease, multiple system atrophy, pure autonomic failure or dementia with Lewy bodies). Materials & methods: A survey including several validated instruments was conducted with informal caregivers of individuals with Parkinson's disease, multiple system atrophy, pure autonomic failure or dementia with Lewy bodies. Results: Caregivers of patients with nOH (n = 60) reported greater burden across all outcomes compared with those without nOH (n = 60). Receiving pharmacological treatment for nOH was the variable most consistently associated with significantly better caregiver health related quality-of-life (p < 0.05). Conclusion: This study demonstrates the burden of nOH on informal caregivers and highlights the potential benefit of pharmacological treatment not only for patients but also indirectly, their caregivers.

Peripheral T-cell lymphomas (PTCL) are a rare and aggressive form of non-Hodgkin's lymphoma that develop from mature T-cells and natural killer cells. Due to the diversity of subtypes and rapidly changing treatment landscape, there is limited understanding of the current real-world PTCL population, including their treatment patterns and adverse event (AE) profile of treatments.
