BACKGROUND The gold standard diagnostic test for obstructive sleep apnoea (OSA) is overnight polysomnography (PSG) which is costly in terms of time and money. Consequently, a number of alternatives to PSG have been proposed. Oximetry is appealing because of its widespread availability and ease of application. The diagnostic performance of an automated analysis algorithm based on falls and recov...
Adjuvant chemotherapy for early breast cancer improves disease-free and overall survival in pre- and postmenopausal women. The importance of maintaining relative dose intensity (RDI) is well-known; however, little information is available from routine clinical practice regarding how well dose intensity is maintained with modern chemotherapy regimens.In a retrospective review of patients undergo...
Previous studies showed good agreement between pacemaker respiratory disturbance index (RDI) and polysomnography for diagnosis of severe sleep apnea (SA). The aim of this study is to investigate the diagnostic accuracy of RDI compared with apnea-hypopnea index (AHI) from a cardiorespiratory sleep study for the diagnosis of severe SA within patients requiring a pacemaker and meeting diastolic dy...
STUDY OBJECTIVES To compare anthropomorphic, nocturnal polysomnographic (PSG), and multiple sleep latency test (MSLT) data between positional (PP) and nonpositional (NPP) obstructive sleep apnea (OSA) patients. DESIGN This is a retrospective analysis of anthropomorphic, PSG, and MSLT data of a large group of OSA patients who underwent a complete PSG evaluation in our sleep disorders unit. The...
با توجه به اهمیت فرآیند حفاری در معادن، لزوم برنامه ریزی و پیش بینی از شرایط پیش رو بیش از پیش احساس می شود. زون بندی توده سنگ های در بر گیرنده مواد معدنی و پیش بینی سرعت حفاری در آن با توجه به حجم بالای عملیات در معادن می تواند به طور جدی شرایط اقتصادی و عملیاتی معدن را تحت تأثیر قرار دهد. در این تحقیق ابتدا به منظور تعیین قابلیت حفاری توده سنگ های معدن سنگ آهن گل گهر ابتدا سابقه علمی موضوع ب...
Correct assessment of the overall treatment effectiveness requires knowledge about therapy compliance and efficacy. This study aimed to determine overall long-term apnoea alleviation after continuous positive airway pressure (CPAP) in a complete sleep laboratory cohort. Out of 209 consecutive CPAP candidates (mean age 57+/-12 yrs, body mass index (BMI) 30.0+/-5.1 kg x m2, respiratory disturbanc...
خشکسالی مشخصه نرمال و طبیعی از اقلیم است که بطور مجازی در تمام رژیم های اقلیمی اتفاق می- افتد. خشکسالی هواشناسی بصورت یک دوره زمانی مشخص می باشدکه در آن دوره بارندگی کمتر از یک مقدار ویژه است.در این تحقیق با کمک شاخص های خشکسالی (spi, rdi)، خشکسالی هواشناسی برای 10 ایستگاه سینوپتیک منتخب کشور که دارای آماری بیش از 30 سال می باشند (با توجه به تنوع اقلیم) با استفاده از مدل زنجیره های مارکوف مدلسا...
Portable sleep studies may play an important role to take decisions on patients referred for suspicion of Sleep Apnea-Hypopnea Syndrome (SAHS). The aim of this study was to evaluate the diagnostic accuracy of automated analysis of ApneaLink in patients with suspicion of SAHS. All participants (75) performed the ApneaLink and polysomnography (PSG) simultaneously in the sleep laboratory. The two ...
Despite the voluminous literature on the role of RDI networks in economic development there are rather few information about their internal structure and functioning. This information is very relevant to highlight the most important factors in favour or against RDI networking. In places where the general circumstances are not really favouring such knowledge intensive collaborations the governme...
