Introduction Patients with refractory chronic migraine have poor quality of life. Intravenous infusions are indicated to rapidly ‘break the cycle’ of pain. Lidocaine infusions may be effective but evidence is limited. Methods The records of 832 hospital admissions involving continuous multiday lidocaine infusions for migraine were reviewed. All patients met criteria for refractory chronic migraine.… Continue reading Lidocaine infusions for refractory chronic migraine: a retrospective analysis

Gut bacterial isoamylamine promotes age-related cognitive dysfunction by promoting microglial cell death
The intestinal microbiome releases a plethora of small molecules. Here, we show that the Ruminococcaceae metabolite isoamylamine (IAA) is enriched in aged mice and elderly people, whereas Ruminococcaceae phages, belonging to the Myoviridae family, are reduced. Young mice orally administered IAA show cognitive decline, whereas Myoviridae phage administration reduces IAA levels. Mechanistically, IAA promotes apoptosis… Continue reading Gut bacterial isoamylamine promotes age-related cognitive dysfunction by promoting microglial cell death
Brain Structure in Acutely Underweight and Partially Weight-Restored Individuals with Anorexia Nervosa – A Coordinated Analysis by the ENIGMA Eating Disorders Working Group
BackgroundThe pattern of structural brain abnormalities in anorexia nervosa (AN) is still not well understood. While several studies report substantial deficits in grey matter volume and cortical thickness in acutely underweight patients, others find no differences, or even increases in patients compared with healthy controls. Recent weight regain before scanning may explain some of this… Continue reading Brain Structure in Acutely Underweight and Partially Weight-Restored Individuals with Anorexia Nervosa – A Coordinated Analysis by the ENIGMA Eating Disorders Working Group
Loss of functional heterogeneity along the CA3 transverse axis in aging
Age-related deficits in pattern separation have been postulated to bias the output of hippocampal memory processing toward pattern completion, which can cause deficits in accurate memory retrieval. Although the CA3 region of the hippocampus is often conceptualized as a homogeneous network involved in pattern completion, growing evidence demonstrates a functional gradient in CA3 along the… Continue reading Loss of functional heterogeneity along the CA3 transverse axis in aging
Varicella zoster meningitis following COVID-19 vaccination: a report of two cases
AbstractMost of the adverse effects reported in patients who have received COVID-19 vaccines have been mild. However, possible serious adverse effects are being monitored cautiously. There have also been a number of case reports of reactivation of varicella zoster infection within 28 days after immunization with mRNA COVID-19 vaccines. A few cases have also been… Continue reading Varicella zoster meningitis following COVID-19 vaccination: a report of two cases
Socioeconomic Disadvantage is Associated with Probable Sarcopenia in Community-Dwelling Older Adults: Findings from the English Longitudinal Study of Ageing
BackgroundSarcopenia is characterized by the accelerated loss of muscle strength, mass, and function in aging. The disease is a major public health issue with emerging evidence of a disproportionate burden in areas of socioeconomic disadvantage. ObjectivesTo estimate the prevalence of probable sarcopenia overall, and according to Socioeconomic Position (SEP). To explore the association between markers… Continue reading Socioeconomic Disadvantage is Associated with Probable Sarcopenia in Community-Dwelling Older Adults: Findings from the English Longitudinal Study of Ageing
Cardiovascular and Cerebrovascular Disease Mortality in Asian American Subgroups
Background:Asian American individuals comprise the fastest-growing race and ethnic group in the United States. Certain subgroups may be at disproportionately high cardiovascular risk. This analysis aimed to identify cardiovascular and cerebrovascular disease mortality trends in Asian American subgroups. Methods:Age-standardized mortality rates (ASMR), average annual percent change of ASMR calculated by regression, and proportional mortality ratios… Continue reading Cardiovascular and Cerebrovascular Disease Mortality in Asian American Subgroups
Supper Timing and Cardiovascular Mortality: The Japan Collaborative Cohort Study
Evidence on the role of supper timing in the development of cardiovascular disease (CVD) is limited. In this study, we examined the associations between supper timing and risks of mortality from stroke, coronary heart disease (CHD), and total CVD. A total of 28,625 males and 43,213 females, aged 40 to 79 years, free from CVD… Continue reading Supper Timing and Cardiovascular Mortality: The Japan Collaborative Cohort Study
Stress-induced protein disaggregation in the endoplasmic reticulum catalysed by BiP
Protein synthesis is supported by cellular machineries that ensure polypeptides fold to their native conformation, whilst eliminating misfolded, aggregation prone species. Protein aggregation underlies pathologies including neurodegeneration. Aggregates’ formation is antagonised by molecular chaperones, with cytoplasmic machinery resolving insoluble protein aggregates. However, it is unknown whether an analogous disaggregation system exists in the Endoplasmic Reticulum… Continue reading Stress-induced protein disaggregation in the endoplasmic reticulum catalysed by BiP
