RESUMEN
Background: Non-cephalgic symptoms including orthostatic intolerance, fatigue, and cognitive impairment, are common in patients with chronic headache disorders and may result from alterations in the autonomic nervous system. However, little is known about the function of autonomic reflexes, which regulate cardiovascular homeostasis and cerebral perfusion in patients with headache. Methods: Autonomic function testing data from patients with headache collected between January 2018 and April 2022 was retrospectively analyzed. Through review of EMR we determined headache pain chronicity and patient self-report of orthostatic intolerance, fatigue, and cognitive impairment. Composite Autonomic Severity Score (CASS), CASS subscale scores, and cardiovagal and adrenergic baroreflex sensitivities were used to quantify autonomic reflex dysfunction. Descriptive analyses (Mann-Whitney-U or χ2, as appropriate) determined associations between autonomic reflex dysfunction and POTS as well as chronic headache. Binomial logistic regression adjusted for age and sex. Spearman's rank correlation determined the association between the total CASS score and the number of painless symptoms reported by each participant. Results: We identified 34 patients meeting inclusion criteria, of whom there were 16 (47.0%) with orthostatic intolerance, 17 (50.0%) with fatigue, 11 (32.4%) with cognitive complaints, and 11 (32.4%) with Postural Orthostatic Tachycardia Syndrome (POTS). The majority of participants had migraine (n = 24, 70.6%), were female (n = 23, 67.6%) and had a chronic (>15 headache days in a month) headache disorder (n = 26, 76.5%). Reduced cardiovagal baroreflex sensitivity (BRS-V) independently predicted chronic headache [aOR: 18.59 (1.16, 297.05), p = 0.039] and POTS [aOR: 5.78 (1.0, 32.5), p = 0.047]. The total CASS was correlated with the total number of non-painful features in the expected direction (r = 0.46, p = 0.007). Conclusion: Abnormal autonomic reflexes may play an important role in pain chronification and the development of POTS in patients with headache.
RESUMEN
The impact of climate change on human health is a topic of critical importance. While only recently beginning to gain attention, it is clear that immediate action is necessary to minimize this impact. In our review, we will outline a subset of these effects in detail. We will examine how climate change has worsened respiratory allergic disease. We will discuss how climate change has altered antigen exposure, possibly disrupting antigen-specific tolerance by the immune system, leading, in turn, to an increase in the prevalence of immunologic diseases. Finally, we will explore how the loss of biodiversity related to climate change may affect the microbiome, potentially leading to dysbiosis, inflammatory, autoimmune and neurologic diseases.

Background: Personal protective equipment (PPE) use is required when caring for COVID-19 patients. Proper mask fitting is essential in prevention of infectious agent transmission at hospital setting.Methods and Results: We describe three cases of health care professionals (HCP) in a COVID-19 designated ward with positive SARS-CoV-2 RT-PCR results, and were found to have improperly fitted masks.Conclusion: These cases of improperly fitting masks in HCP may have contributed to their eventual COVID-19 infection. These cases raise the important issue of PPE fitting. Abbreviations: Personal Protective Equipment (PPE), Health Care Professional (HCP), Real-time PCR (RT-PCR).

The topics of climate change and ecosystem disruption are at the forefront of global discussion. Accordingly, there is a sense of urgency among citizens, environmental experts, and political leaders for action and policy change. While the effect of a changing climate on the environment is well recognized, its impact on the human body has not been sufficiently described. In our review, we will attempt to outline some of these effects. We will discuss how the recent surge of immunologic disease may be related to the changing profile of microorganisms and antigens in our every-day environment. We will explore how the introduction of antibiotics may result in an altered gut microbiome, and subsequently abnormal neurodevelopment. Finally, we will discuss a possible link between chemical preservatives and neoplastic disease.

Attention-deficit/hyperactivity disorder (ADHD) is a neurologic disorder characterized by hyperactivity/impulsivity and/or inattentiveness, with genetic and environmental factors contributing to the disorder. With the growing recognition of the microbiome's role in many neurological disorders, the authors propose that it may also be implicated in ADHD. Here, we describe several evolving areas of research to support this hypothesis. First, a unique composition of gut bacteria has been identified and linked to behaviors in ADHD. Second, our research found an increased incidence of 2 gastrointestinal symptoms (constipation and flatulence) in children with ADHD, as compared to controls. Finally, emerging data may be interpreted to suggest that immune dysregulation in ADHD be associated with an altered microbiome, low-grade inflammation, and gastrointestinal dysfunction. Although more studies are needed to elucidate exact mechanisms and causality, we propose that an altered microbiome, gastrointestinal symptoms, and immune dysregulation may be associated with the ADHD phenotypes.
