Jonathan M Peake, Oliver Neubauer, Neil P Walsh, Richard J Simpson
The notion that prolonged, intense exercise causes an 'open window' of immunodepression during recovery after exercise is well accepted. Repeated exercise bouts or intensified training without sufficient recovery may increase the risk of illness. However, except for salivary IgA, clear and consistent markers of this immunodepression remain elusive. Exercise increases circulating neutrophil and monocyte counts, and reduces circulating lymphocyte count during recovery. This lymphopenia results from preferential egress of lymphocyte subtypes with potent effector functions (e...

BACKGROUND: Autism spectrum disorder (ASD) is still diagnosed through behavioral observation, due to a lack of laboratory biomarkers, which could greatly aid clinicians in providing earlier and more reliable diagnoses. Metabolomics on human biofluids provides a sensitive tool to identify metabolite profiles potentially usable as biomarkers for ASD. Initial metabolomic studies, analyzing urines and plasma of ASD and control individuals, suggested that autistic patients may share some metabolic abnormalities, despite several inconsistencies stemming from differences in technology, ethnicity, age range, and definition of "control" status...

BACKGROUND: A number of social drinkers claim that they do not experience next-day hangovers despite consuming large quantities of alcohol. The aim of this study was to investigate the characteristics of drinkers who claim to be hangover immune and compare them with drinkers who do report having hangovers. METHODS: A total of 36 social drinkers participated in a naturalistic study consisting of a hangover day (alcohol consumed) and a control day (no alcohol consumed)...

Gan-Dan-Liang-Yi-Tang (GDLYT) is a Traditional Chinese Medicine that has been historically used for the treatment of insomnia. However, investigations into its pharmacological ingredients and the mechanism underlying its sedative and hypnotic effects remain limited. The present study reported the detailed mechanisms underlying the sedative and hypnotic effects of GDLYT. Kunming mice were administered GDLYT at various sub-hypnotic doses, which underwent sodium pentobarbital treatment test, pentetrazole induced convulsant studies and p-chlorophenylalanine (PCPA) induced insomnia model...

The aim of this article was to examine the associations between having had a sinus infection (SI) and BMI and physical activity (PA), diet quality, stress and/or sleep. A total of 2915 adults from the National Health and Nutrition Examination Survey 2005-2006 were examined. Logistic regression analysis was used to examine the association between having had an SI with BMI and PA, diet quality, stress or sleep. As these factors are known to influence one another, a fully adjusted model with PA, diet quality, stress and sleep was also constructed to examine their independent associations with having had an SI...

The parasite Trypanasoma brucei causes African trypanosomiasis, known as sleeping sickness in humans and nagana in domestic animals. These diseases are a major burden in the 36 sub-Saharan African countries where the tsetse fly vector is endemic. Untreated trypanosomiasis is fatal and the current treatments are stage-dependent and can be problematic during the meningoencephalitic stage, where no new therapies have been developed in recent years and the current drugs have a low therapeutic index. There is a need for more effective treatments and a better understanding of how these parasites evade the host immune response will help in this regard...

BACKGROUND: During critical illness sleep is important for immune function and restorative processes. Despite theoretical evidence and scientific understanding of the effects of sleep deprivation in the critically ill, research is yet to be entirely translated into institutional practices and department cultural norms. OBJECTIVES: This article was adapted from an undergraduate essay that considered the nurse's role in addressing fragmented sleep in critical care patients'...

Narcolepsy type 1 is a devastating neurological sleep disorder resulting from the destruction of orexin-producing neurons in the central nervous system (CNS). Despite its striking association with the HLA-DQB1*06:02 allele, the autoimmune etiology of narcolepsy has remained largely hypothetical. Here, we compared peripheral mononucleated cells from narcolepsy patients with HLA-DQB1*06:02-matched healthy controls using high-dimensional mass cytometry in combination with algorithm-guided data analysis. Narcolepsy patients displayed multifaceted immune activation in CD4(+) and CD8(+) T cells dominated by elevated levels of B cell-supporting cytokines...

The magnitude which sleep has on personal well-being is similar to the effects of diet and exercise. Sleep deprivation has severe negative effects on an individual's overall health, and this is usually overseen. From 30 to 40 % of the population has presented insomnia at a certain moment of life and from 9 to 15 % have evolved into a chronic and severe insomnia. Recent investigations have related sleep deprivation with obesity, metabolic disorders, heart disease, mental health problems and dementia. Recently, more investigations have focused on the multiple alterations suffered by the immune system in cases of sleep deprivation...

Trypanosoma brucei, a protozoan parasite that causes both Human and Animal African Trypanosomiasis (known as sleeping sickness and nagana, respectively) cycles between a tsetse vector and a mammalian host. It evades the mammalian host immune system by periodically switching the dense, variant surface glycoprotein (VSG) that covers its surface. The detection of antigenic variation in Trypanosoma brucei can be both cumbersome and labor intensive. Here, we present a method for quantifying the number of parasites that have 'switched' to express a new VSG in a given population...

A reduction in the activity of GABAA receptors, particularly α5 subunit-containing GABAA receptors (α5GABAARs), has been implicated in the etiology of Autism Spectrum Disorders (ASD). Genetically modified mice that lack α5GABAARs (Gabra5(-/-)) exhibit autism-like behaviors and both enhanced and impaired learning and memory, depending on the behavioral task. The aim of this study was to examine the electroencephalogram (EEG) activity and sleep-wake behaviors in Gabra5(-/-) mice and wild-type mice. In addition, since some individuals with ASD can exhibit elevated innate immune response, mice were treated with lipopolysaccharide (LPS; 125mg/kg intraperitoneal injection) or vehicle and EEG and sleep-wake patterns were assessed...

People living with chronic inflammatory bowel disease (IBD) experienced that knowledge about their embodied tolerance limits, diet, mental problem solving, and change in lifestyle together with integrative health care could promote recovery from their diagnosed disease in calmer periods of suffering. A hermeneutic approach was used to analyze interviews with patients living with IBD outside hospitals. Thirteen young adults between 18 and 45 years of age in calmer phases of IBD participated in the study. Three main themes emerged from the analysis of the interviews: (1) Understanding limits in embodied tolerance, (2) Restoring balance is creating a new equilibrium, and (3) Creating resilience through integrative care...

BACKGROUND: Sleep is integral to biologic function, and sleep disruption can result in both physiological and psychologic dysfunction including cognitive decline. Surgery activates the innate immune system, inducing neuroinflammatory changes that interfere with cognition. Because surgical patients with sleep disorders have an increased likelihood of exhibiting postoperative delirium, an acute form of cognitive decline, we investigated the contribution of perioperative sleep fragmentation (SF) to the neuroinflammatory and cognitive responses of surgery...

Hypertension (HTN) is the most prevalent modifiable risk for cardiovascular disease (CVD) and disorders directly influencing CVD (i.e. obesity, diabetes, chronic kidney disease, obstructive sleep apnea, etc.). About one billion people worldwide have HTN, with American adults having 90% lifetime risk of developing HTN. Despite aggressive campaign for lifestyle changes and advances in drug therapy, HTN remains an immense health, emotional, and economic challenge. This is due, in part, to the fact that ∼50% of HTN patients' blood pressure remains uncontrolled and ∼20% of HTN patients are resistant to or require > antihypertensive drugs...

Sleep specialists have proposed measures to counteract the negative short- and long-term consequences of sleep debt, and some have suggested the nap as a potential and powerful "public health tool". Here, we address this countermeasure aspect of napping viewed as an action against sleep deprivation rather than an action associated with poor health. We review the physiological functions that have been associated positively with napping in both public health and clinical settings (sleep-related accidents, work and school, and cardiovascular risk) and in laboratory-based studies with potential public health issues (cognitive performance, stress, immune function and pain sensitivity)...

Adrenal glucocorticoids are major modulators of multiple functions, including energy metabolism, stress responses, immunity, and cognition. The endogenous secretion of glucocorticoids is normally characterized by a prominent and robust circadian (around 24 hours) oscillation, with a daily peak around the time of the habitual sleep-wake transition and minimal levels in the evening and early part of the night. It has been long recognized that this 24-h rhythm partly reflects the activity of a master circadian pacemaker located in the suprachiasmatic nucleus of the hypothalamus...

STUDY OBJECTIVE: The presence of obstructive sleep apnea (OSA) in patients with cancer appears to be accompanied by poorer outcomes. However, the mechanisms underlying such association are unknown. Tumor infiltrating lymphocytes (TILs), including CD8+ T cells, function as cytotoxic T lymphocytes (CTLs), and mount immune responses to cancer by the release of cytolytic enzymes, including granzyme B (GzmB), perforin (Prf) and cytokines such as interferon (IFN)-γ. METHODS: Using established in vivo mouse models, we investigated CD8+ T cells and cancer stem cells (CSC) in intermittent hypoxia (IH) and sleep fragmentation (SF) in the context of tumor environment...

Obstructive sleep apnea (OSA) causes daytime fatigue and sleepiness, and has an established relationship with cardiovascular and metabolic disease. Recent years have seen the emergence of an evidence base linking OSA with an increased risk of degenerative neurological disease and associated cognitive impairment, an accelerated rate of decline in kidney function with an increased risk of clinically significant chronic kidney disease (CKD), and with a significantly higher rate of cancer incidence and death. This review evaluates the evidence base linking OSA with these seemingly unrelated co-morbidities, and explores potential mechanistic links underpinning their development in patients with OSA, including intermittent hypoxia (IH), sleep fragmentation, sympathetic excitation, and immune dysregulation...
