PURPOSE OF REVIEW: Obesity is recognized as a chronic and recurring disease, often accompanied by other weight-related comorbid conditions such as obstructive sleep apnea, hypertension, type 2 diabetes, and non-alcoholic fatty liver disease (NAFLD). This chapter will seek to focus on the effect of weight loss surgery (WLS), in particular Roux-en-Y gastric bypass (RYGB), on NAFLD. RECENT FINDINGS: Among several modalities available to treat NAFLD, the one most likely to achieve rapid, significant, and sustained improvement of liver disease is WLS...

BACKGROUND: Apraxia of eyelid opening (AEO) primarily has been described as bilateral loss of volitional ability to open the eyes at certain times and often associated with neurodegenerative disease. Rarely, it can occur in isolation and as an idiopathic phenomenon. There are a few reports of unilateral AEO only on awakening from sleep. We report an additional 11 patients with this unusual variation of AEO. METHODS: Retrospective, observational case series of patients collected from 3 separate neuro-ophthalmology practices...

Over the course of the day, the heart is challenged with dramatic fluctuations in energetic demand and nutrient availability. It is therefore not surprising that rhythms in cardiac metabolism have been reported at multiple levels, including the utilization of glucose, fatty acids, and amino acids. Evidence has emerged suggesting that the cardiomyocyte circadian clock is in large part responsible for governing cardiac metabolic rhythms. In doing so, the cardiomyocyte clock temporally partitions ATP generation for increased contractile function during the active period, promotes nutrient storage at the end of the active period, and facilitates protein turnover (synthesis and degradation) during the beginning of the sleep phase...

Acute symptomatic seizures and epileptic disorders are frequent health problems of elderly patients. An early and reliable distinction of the seizure etiology is important to ensure adequate treatment, and to prevent unwarranted diagnostic and therapeutic procedures. The most common causes of acute symptomatic seizures - acute cerebrovascular disorders, metabolic disorders, traumatic brain injury, meningo-encephalitis, cerebral tumors, and withdrawal of alcohol and other central agents - are well-defined and seem to permit straightforward diagnostic and therapeutic strategies...

OBJECTIVE: This study aimed to identify the subtype of interictal ripples that help delineate the epileptogenic zone in neocortical epilepsy. METHODS: Totally 25 patients with focal neocortical epilepsy who had invasive electroencephalography (EEG) evaluation and subsequent surgery were included. They were followed up for at least 2years. Interictal ripples (80-250Hz) and fast ripples (250-500Hz) during slow-wave sleep were identified. Neocortical ripples were defined as type I ripples when they were superimposed on epileptiform discharges, and as type II ripples when they occurred independently...

Dementia syndromes associated with Lewy bodies are subdivided into dementia with Lewy bodies (DLB), an underdiagnosed cause of dementia in the elderly, and Parkinson disease with dementia (PDD), cognitive impairment appearing in people diagnosed with Parkinson disease. Their neuropathologic substrates are the widespread distribution of aggregates of the protein α-synuclein in neurons in cortical brain regions, accompanied by variable Alzheimer pathology. Clinical features of DLB and PDD include distinctive changes in cognition, behavior, movement, sleep, and autonomic function...

Crosstalk between the lung and the kidney is based on the similarities that these organs share. This is why different diseases that affect one organ can have repercussions on the other. Patients with acute kidney injury can present complications such as pulmonary edema and require mechanical ventilation in respiratory failure. This interaction occurs due to the increase in systemic immune mediators that cause inflammatory reactions, oxidative stress, and an increase in vascular permeability in the lung. With regard to lung-induced renal damage, the kidney can also be affected by chemical mediators, which are translocated into the bloodstream...

The notion that oxidative stress plays a role in virtually every human disease and environmental exposure has become ingrained in everyday knowledge. However, mounting evidence regarding the lack of specificity of biomarkers traditionally used as indicators of oxidative stress in human disease and exposures now necessitates re-evaluation. To prioritize these re-evaluations, published literature was comprehensively analyzed in a meta-analysis to quantitatively classify the levels of systemic oxidative damage across human disease and in response to environmental exposures...

Mutations in the cardiac sodium channel gene SCN5A may result in various arrhythmia syndromes such as long QT syndrome type 3 (LQTS), Brugada syndrome (BrS), sick sinus syndrome (SSS), cardiac conduction diseases (CCD) and possibly dilated cardiomyopathy (DCM). In most of these inherited cardiac arrhythmia syndromes the phenotypical expression may range from asymptomatic phenotypes to sudden cardiac death (SCD). A 16-year-old female died during sleep. Autopsy did not reveal any explanation for her death and a genetic analysis was performed...

BACKGROUND: Sleep complaints are prevalent in older patients. Sleepiness, short or long sleep duration and obstructive sleep apnea (OSA) are associated with insulin resistance (IR). These parameters have not yet been considered together in the same study exploring the possible association between IR and sleep in older patients. IR is involved in cardiovascular and metabolic diseases, pathologies which are highly prevalent in older patients. Here we assess, in older non-diabetic patients with sleep complaints, the associations between IR and sleep parameters objectively recorded by polysomnography (PSG) rather than self-report...

This study aimed to compare the critical flicker frequency (CFF) and the mail-in cognitive function screening ınstrument (MCFSI) tests' effectiveness in diagnosing neurocognitive function losses in patients having severe obstructive sleep apnea syndrome (OSAS). A total of 85 subjects (47 patients with a diagnosis of severe OSAS and 38 healthy controls) were included into the study. MCFSI scores greater than or equal to five and CFF scores less than 39 Hz were considered abnormal. Demographic and polysomnographic parameters of patients with OSAS were studied, and correlations between the MCFSI, CFF scores and Epworth Sleepiness Scale (ESS) scores were analysed...

INTRODUCTION: Type I is the most common Chiari malformation in children. In this condition, the lower part of the cerebellum, but not the brain stem, extends into the foramen magnum at the base of the skull leading to intermittent brain hypertension. In symptomatic children, central sleep apneas are shown in polysomnography evaluation. A central apnea index of 1/h or more is considered abnormal, but >5/h is clearly considered pathological. Therefore, central sleep apnea evaluation in pediatric age may show great age-related variability...

Ageing is an inevitable biological process that results in a progressive structural and functional decline, as well as biochemical alterations that altogether lead to reduced ability to adapt to environmental changes. As clock oscillations and clock-controlled rhythms are not resilient to the aging process, aging of the circadian system may also increase susceptibility to age-related pathologies such as Alzheimer's disease (AD). Besides the amyloid-beta protein (Aβ)-induced metabolic decline and neuronal toxicity in AD, numerous studies have demonstrated that the disruption of sleep and circadian rhythms is one of the common and earliest signs of the disease...
