Compliance to ventilatory treatment in a cohort of patients on home CPAP or NIV: analysis by diagnosis, treatment type, and comorbidities

2019

Background: Patients on home continuous positive airway pressure (CPAP) or noninvasive ventilation (NIV) show large variability in compliance to treatment. Aim: To identify predictors of poor compliance, we evaluated compliance to treatment in patients with obstructive sleep apnea (OSA), obesity hypoventilation syndrome (OHS), and OSA-chronic obstructive pulmonary disease (COPD) overlap syndrome. Methods: We analyzed clinical and compliance data provided by a single home care provider, in 602 patients (n=442 OSA, males (M) 308; 38 OHS M=15, and 122 overlap M=111) on home CPAP/NIV in the province of Agrigento, Italy, after one year of treatment. The following variables were considered: age, …

Incident cardiovascular events in severely obese patients treated with continous positive airway pressure (CPAP)/non invasive ventilation (NIV): A 5.…

2015

it is still debated whether CPAP or non-invasive ventilation (NIV) reduces cardiovascular (CV) risk in morbidly obese patients. Obese subjects affected by obstructive sleep apnea (OSA) or obesity hypoventilation syndrome (OHS) (n=210) were recruited between 2007-2010 in the Sleep Center, Univ. of Grenoble; 152 of them were treated with CPAP or NIV, and regularly followed by a home-care provider (Agir a dom). Patients underwent phone interviews to assess incident CV events during 5.6 years (range 4.0-6.5 yrs) of follow-up. One hundred seventeen patients (63 men) responded to questionnaire, 3 OSA patients died, and 32 declined/were lost to follow-up (response rate 77%). All patients at baseli…

Impact of obstructive sleep apnea on metabolic dysfunction in severe obesity.

2011

Obstructive Sleep Apnoea (OSA) seems to worsen metabolism. This effect has not evaluated in morbid obesity (MO). We hypothesized that the metabolic profile is more impaired in MO patients with OSA than in those without and investigated whether any specific metabolic dysfunction is related to OSA in MO. A prospective multi-centre cross-sectional study was conducted in consecutive subjects before bariatric surgery. OSA was defined as apnoea-hypopnoea index (AHI)≥15 by overnight polysomnography (PSG). Anthropometrical, blood pressure (BP) and fasting blood measurements were obtained the morning after. Metabolic Syndrome (MetS) was defined according to NCEP ATPIII modified criteria. 159 patient…

Heart rate variability during sleep in patients with schizophrenia treated with olanzapine.

2004

Cardiac adverse events in patients treated with atypical antipsychotics have gained increasing interest in recent years. In the present study, heart rate variability (HRV), which is a sensitive parameter reflecting central autonomic cardiac control, was investigated during treatment with olanzapine. Ten physically healthy male patients with schizophrenia, who displayed predominantly negative symptoms, were studied in the sleep laboratory under drug-free baseline conditions and after 4 weeks of olanzapine medication. HRV was assessed during different sleep stages both in the time and frequency domains. Only slight changes in HRV were shown during treatment, and appeared to be independent of …

Nocturnal hormone profiles in patients with schizophrenia treated with olanzapine.

2005

Summary Nocturnal hormone profiles were measured in patients with schizophrenia with predominantly negative symptoms both under drug-free baseline conditions and after subchronic administration of the atypical antipsychotic olanzapine, with the aim of characterizing its pharmacological properties on the neuroendocrine level. The following hormones were studied in the sleep laboratory under polysomnographic control: adrenocorticotrophic hormone, cortisol, growth hormone (GH), prolactin, testosterone, and melatonin. Blood samples were taken at regular time intervals over the night, and serum concentrations of the hormones were determined. Ten patients completed the study, two of them were exc…

Is APOE ε4 associated with cognitive performance in early MS?

2020

ObjectiveTo assess the impact of APOE polymorphisms on cognitive performance in patients newly diagnosed with clinically isolated syndrome (CIS) or relapsing-remitting MS (RRMS).MethodsThis multicenter cohort study included 552 untreated patients recently diagnosed with CIS or RRMS according to the 2005 revised McDonald criteria. The single nucleotide polymorphisms rs429358 (ε4) and rs7412 (ε2) of the APOE haplotype were assessed by allelic discrimination assays. Cognitive performance was evaluated using the 3-second paced auditory serial addition test and the Multiple Sclerosis Inventory Cognition (MUSIC). Sum scores were calculated to approximate the overall cognitive performance and memo…

Behavioural sensitization to repeated sleep deprivation in a mice model of mania.

2008

Sensitization to the effect of stress has been hypothesized as a mechanism to explain episode recurrence and cycle acceleration in bipolar disorder. Naturalistic observations and experimental work in human patients suggested that sleep deprivation can trigger manic episodes of illness. In rats sleep deprivation (SD) with the platform method caused mania-like behaviours thus providing an animal model of mania with face, construct, and predictive validity. In the present study we administered SD or control stress to male CD1 mice following a dose-response protocol based on time of exposure to the experimental conditions (6, 12 or 24 h) and repetition of treatment (three times). SD, but not st…

Treatment of snoring disorder with a non-ablactive Er:YAG laser dual mode protocol. An interventional study

2020

Background Snoring disorder is a common problem among world population. Treatment modalities may involve surgical and non-surgical procedures. As main objective we proposed to evaluate the efficacy of non-ablative Er:YAG laser in the treatment of snoring disorder. Material and Methods We performed an interventional study in 30 patients with snoring disorders. Three sessions were performed with Er:YAG laser 2940nm in long pulse mode (2J/cm2) and smooth mode (10-8J/cm2) in oropharynx region. We analyzed the efficacy of this protocol using questionnaires for snoring intensity, snoring related characteristics of quality of life (including the Epworth sleepness scale and OHIP-14), the satisfacti…
