AI Article Synopsis
- This study investigates brain fog in COVID-19 patients, focusing on its clinical features and societal impact, particularly on work productivity.
- A cohort of 1,009 hospitalized patients was analyzed, revealing that brain fog symptoms decreased after 3 months but remained stable up to 12 months, with certain neurological symptoms correlating to higher brain fog instances.
- Key risk factors were identified, including advanced age, female sex, obesity, and pre-existing respiratory issues, with findings indicating that brain fog negatively affects labor productivity.
Article Abstract
Objective: To reveal the clinical features and assess risk factors linked to brain fog and its societal implications, including labor productivity, providing valuable insights for the future care of individuals who have experienced coronavirus disease 2019 (COVID-19).
Methods: We analyzed a comprehensive cohort dataset comprising 1,009 patients with COVID-19 admitted to Japanese hospitals. To assess brain fog, we analyzed patients who responded to a questionnaire indicating symptoms such as memory impairment and poor concentration.
Results: The prevalence of brain fog symptoms decreased 3 months posthospitalization but remained stable up to 12 months. Neurological symptoms such as taste and smell disorders and numbness at hospitalization correlated with a higher frequency of identifying brain fog as a long COVID manifestation. Our findings indicated that advanced age, female sex, a high body mass index, oxygen required during hospitalization, chronic obstructive pulmonary disease, asthma, and elevated C-reactive protein and elevated D-dimer levels were risk factors in patients exhibiting brain fog. Additionally, we demonstrated the negative impact of brain fog on labor productivity by presenteeism scores.
Interpretations: This study clarified the clinical characteristics of patients experiencing brain fog as a long COVID manifestation, specifically emphasizing neurological symptoms during hospitalization and their correlation with brain fog. Additionally, the study identified associated risk factors for its onset and revealed that the emergence of brain fog was linked to a decline in labor productivity.

Background: Bipolar disorder (BD) imposes significant social, psychological, and economic burdens on individuals and their caregivers. While developing treatments for BD patients is crucial, supportive interventions for caregivers in low- and middle-income countries (LMICs) are equally important, given the limited resources and healthcare infrastructure. Understanding caregiver experiences in these settings is essential for creating effective interventions.

Background: The goal of this study was to examine autonomic nervous system function by measuring heart rate (HR), heart rate variability (HRV), skin conductance levels (SCL), and peripheral skin temperature (ST) in response to and during recovery from psychosocial stressors in patients with functional somatic syndromes (FSS; fibromyalgia and/or chronic fatigue syndrome), stress-related syndromes (SRS; overstrain or burn-out), and healthy controls (HC).
Methods: Patients with FSS (n = 26), patients with SRS (n = 59), and HC (n = 30) went through a standardized psychosocial stress test consisting of a resting phase (120 s), the STROOP color word task (120 s), a mental arithmetic task (120 s) and a stress talk (120 s), each followed by a 120 s recovery period. HR, HRV, SCL, and ST were monitored continuously.

Introduction: Transcutaneous auricular vagus nerve stimulation (tVNS) has shown potential in neurological, autoimmune, and cardiovascular disorders, but its effects on HD patients remain unclear. This study aimed to evaluate the efficacy and safety of tVNS in HD patients.
Methods: We conducted a randomized controlled clinical trial on patients receiving HD ≥6 months.

Purpose: The purpose of this study was to use the advanced technique of Network Intervention Analysis (NIA) to investigate the trajectory of symptom change associated with the effects of self-control training on youth university students' chronic ego depletion aftereffects.
Methods: The nine nodes of chronic ego depletion aftereffects and integrated self-control training were taken as nodes in the network and analyzed using NIA. Networks were computed at the baseline, at the end of treatment, at 1-, 3-, 6-, 9- and 12-month follow up.

The transition to menopause is associated with disappearance of menstrual cycle symptoms and emergence of vasomotor symptoms. Although menopausal women report a variety of additional symptoms, it remains unclear which emerge prior to menopause, which occur in predictable clusters, how clusters change across the menopausal transition, or if distinct phenotypes are present within each life stage. We present an analysis of symptoms in premenopausal to menopausal women using the MenoLife app, which includes 4789 individuals (23% premenopausal, 29% perimenopausal, 48% menopausal) and 147,501 symptom logs (19% premenopausal, 39% perimenopausal, 42% menopausal).
