Individuals with insulin resistance and low cardiorespiratory fitness are frequently found to have an increased waist circumference and high exercise blood pressure. We tested the hypothesis that the relationships among insulin resistance, low cardiorespiratory fitness, and increased exercise blood pressure may be mediated by an elevated waist circumference. This study included 317 apparently h...

The main purpose of this study is the survey of the atmospheric low pressure effects at sea level oscillations in the Qeshm Channel. For this purpose, the curves of the pressure on the Persian Gulf and Oman Sea, during the passing of the atmospheric low pressure system, are extracted across the region. During the time of occurrence of these events, sea level oscillations in the coastal areas of...

STUDY OBJECTIVES The effectiveness of nasal continuous positive airway pressure (CPAP) in treating obstructive sleep apnea (OSA) is based on raising the intramural pressure above a critical collapsing pressure of the oropharyngeal airway. It is currently unclear whether CPAP delivered orally is also capable of raising pressure in the oropharynx above the critical collapse pressure. DESIGN We ...

OBJECTIVE To determine whether a set of physical symptoms is associated with low blood pressure and to investigate the possible role of psychological factors in their occurrence. DESIGN Analysis of data collected by questionnaire and physical screening from the first phase of the Whitehall II study, a cohort study of an employed population. SETTING 23 civil service departments in London. ...

distributions of blood pressure might be more susceptible to the hypertensive effects of oral contraceptives: studies in the United States found higher mean blood pressures in black compared with white adults, and in England in both factory workers13 and civil servants14 black men had higher mean blood pressures than white men. In our study, however, we found no differences between black and wh...

OBJECTIVES To study outcome of patients with scorpion envenomation treated with oral captopril in the ICU of a Tertiary Care, University Hospital in Mumbai. METHODS Retrospective analysis of all patients with scorpion sting admitted to Medical Intensive Care Unit of a tertiary care university hospital in Mumbai between 1993 and 2003. RESULTS Of 38 patients with cardiovascular manifestations...

Ischemic tracheal complications due to the ETT cuff occur in approximately 10 percent of mechanically ventilated critically ill patients despite the use of high-volume, low-pressure ETT cuffs. Using a laboratory model, we studied the effects of airway pressure on three different ETT cuff designs, including two "low pressure" designs. Positive airway pressure acted on the "low pressure" cuffs to...
