The National High Blood Pressure Education Program presents the complete Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure. Like its predecessors, the purpose is to provide an evidence-based approach to the prevention and management of hypertension. The key messages of this report are these: in those older than age 50, systolic blood pressure (BP) of greater than 140 mm Hg is a more important cardiovascular disease (CVD) risk factor than diastolic BP; beginning at 115/75 mm Hg, CVD risk doubles for each increment of 20/10 mm Hg; those who are normotensive at 55 years of age will have a 90% lifetime risk of developing hypertension; prehypertensive individuals (systolic BP 120-139 mm Hg or diastolic BP 80-89 mm Hg) require health-promoting lifestyle modifications to prevent the progressive rise in blood pressure and CVD; for uncomplicated hypertension, thiazide diuretic should be used in drug treatment for most, either alone or combined with drugs from other classes; this report delineates specific high-risk conditions that are compelling indications for the use of other antihypertensive drug classes (angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, beta-blockers, calcium channel blockers); two or more antihypertensive medications will be required to achieve goal BP (<140/90 mm Hg, or <130/80 mm Hg) for patients with diabetes and chronic kidney disease; for patients whose BP is more than 20 mm Hg above the systolic BP goal or more than 10 mm Hg above the diastolic BP goal, initiation of therapy using two agents, one of which usually will be a thiazide diuretic, should be considered; regardless of therapy or care, hypertension will be controlled only if patients are motivated to stay on their treatment plan. Positive experiences, trust in the clinician, and empathy improve patient motivation and satisfaction. This report serves as a guide, and the committee continues to recognize that the responsible physician's judgment remains paramount.

The development and use of a new scale, the Epworth sleepiness scale (ESS), is described. This is a simple, self-administered questionnaire which is shown to provide a measurement of the subject's general level of daytime sleepiness. One hundred and eighty adults answered the ESS, including 30 normal men and women as controls and 150 patients with a range of sleep disorders. They rated the chances that they would doze off or fall asleep when in eight different situations commonly encountered in daily life. Total ESS scores significantly distinguished normal subjects from patients in various diagnostic groups including obstructive sleep apnea syndrome, narcolepsy and idiopathic hypersomnia. ESS scores were significantly correlated with sleep latency measured during the multiple sleep latency test and during overnight polysomnography. In patients with obstructive sleep apnea syndrome ESS scores were significantly correlated with the respiratory disturbance index and the minimum SaO2 recorded overnight. ESS scores of patients who simply snored did not differ from controls.

Background Limited data have suggested that sleep-disordered breathing, a condition of repeated episodes of apnea and hypopnea during sleep, is prevalent among adults. Data from the Wisconsin Sleep Cohort Study, a longitudinal study of the natural history of cardiopulmonary disorders of sleep, were used to estimate the prevalence of undiagnosed sleep-disordered breathing among adults and address its importance to the public health. Methods A random sample of 602 employed men and women 30 to 60 years old were studied by overnight polysomnography to determine the frequency of episodes of apnea and hypopnea per hour of sleep (the apnea-hypopnea score). We measured the age- and sex-specific prevalence of sleep-disordered breathing in this group using three cutoff points for the apnea-hypopnea score (≥ 5, ≥ 10, and ≥ 15); we used logistic regression to investigate risk factors. Results The estimated prevalence of sleep-disordered breathing, defined as an apnea-hypopnea score of 5 or higher, was 9 percent for w...

Systematic trends in the length of apneas were investigated in 8 sleep apnea patients, all of whom had more than 200 apneas per night. Regression analysis performed on the length of apneas by thirds of the night revealed significant linear trends for apneas in sleep stage 2, and for apneas in all sleep stages pooled together. There were no significant trends in the index of apnea density. We suggest that the across-night lengthening of apneas reflects a progressive increase in the arousal threshold, either by a compensatory deepening of sleep or by progressive changes in respiratory chemoreceptor sensitivity. The lack of significant trends in rapid eye movement (REM) sleep supports the conclusion that apnea termination in REM sleep is mediated by a different mechanism than in non-REM sleep.

Across-night lengthening of sleep apneic episodes.

Twenty-five adults with a deviated nasal septum, who complained about excessive daytime sleepiness, chronic fatigue, and nocturnal insomnia, were studied for one to two nights in a sleep laboratory. Recordings disclosed disordered breathing during sleep in the form of pronounced periodic breathing of alternating hypopneas and hyperpneas, isolated hypopneic episodes and central apneas and periodic sighs, all combined with electrophysiologic "microarousals," and a mixture of alpha and delta EEG wave activities. Surgical treatment of the deviated septum in 14 patients resulted in a subjective improvement in the level of diurnal alertness and in the quality of nocturnal sleep in 12 patients. Follow-up sleep recordings in seven of the patients who reported subjective improvement in sleep disclosed notably less waking and abnormal breathing during sleep. These results suggest that increased upper airway resistance can cause nonapneic breathing disorders in sleep and, consequently, sleep disturbances.

Excessive daytime sleepiness and insomnia.

BACKGROUND: Disturbed sleep is a common complaint among patients with PTSD. This complaint can be found in both the reexperiencing and hyperarousal symptom clusters in the DSM-IV. However, laboratory studies of sleep in PTSD have provided inconsistent evidence of objective sleep disturbances. Shortened REM latency, reduced sleep efficiency, restless sleep and increased prevalence of sleep apnea have been reported, but were not confirmed by all. A major shortcoming of most previous studies is the fact that they were done retrospectively in patients with chronic PTSD, often complicated by psychiatric comorbidity and drug abuse. Thus, little is known about the development of sleep disturbances in recently traumatized subjects. METHOD: Eight injured victims of traffic accidents with PTSD and 6 injured victims without PTSD participated in a 3-night polysomnographic study one year after the accident. RESULTS: No significant differences between PTSD and non-PTSD patients were noted on any of the PSG measures. In addition, the two groups did not differ significantly from each other with respect to awakening thresholds during REM sleep. CONCLUSION: Considering that the present sample was free of active psychiatric comorbidity at the time of trauma and free of hypnotic medications, these results strengthen previous PSG studies suggesting that altered sleep perception, rather than sleep disturbance per se, may be the key problem in PTSD. More research is needed in order to examine whether this problem is specific to sleep or generalizes to other domains as well. Language: en

No evidence of sleep disturbance in post-traumatic stress disorder: a polysomnographic study in injured victims of traffic accidents.

Prolonged neutrophil survival is evident in various cardiovascular and respiratory morbidities, in hypoxic conditions in-vitro and in patients with obstructive sleep apnea (OSA) characterized by nightly intermittent hypoxia (IH). This may lead to persistent inflammation, tissue injury and dysfunction. We therefore investigated by a translational approach the potential contribution of the intrinsic stress-induced mitochondrial pathway in extending neutrophil survival under IH conditions. Thus, neutrophils of healthy individuals treated with IH in-vitro and neutrophils of OSA patients undergoing nightly IH episodes in-vivo were investigated. Specifically, the balance between pro-apoptotic Bax and anti-apoptotic Mcl-1 protein expression, and the potential involvement of p38MAPK and ERK1/2 signaling pathways in the control of Mcl-1 expression were investigated. Purified neutrophils were exposed to IH and compared to normoxia and to sustained hypoxia (SH) using a BioSpherix-OxyCycler C42 system. Bax and Mcl-1 levels, and p38MAPK and ERK1/2 phosphorylation were determined by western blotting. Also, Bax/Mcl-1 expression and Bax translocation to the mitochondria were assessed by confocal microscopy in pre-apoptotic neutrophils, before the appearance of apoptotic morphology. Co-localization of Bax and mitochondria was quantified by LSM 510 CarlZeiss MicroImaging using Manders Overlap Coefficient. A paired two-tailed t test, with Bonferroni correction for multiple comparisons, was used for statistical analysis. Compared to normoxia, IH and SH up-regulated the anti-apoptotic Mcl-1 by about 2-fold, down-regulated the pro-apoptotic Bax by 41% and 27%, respectively, and inhibited Bax co-localization with mitochondria before visible morphological signs of apoptosis were noted. IH induced ERK1/2 and p38MAPKs phosphorylation, whereas SH induced only p38MAPK phosphorylation. Accordingly, both ERK and p38MAPK inhibitors attenuated the IH-induced Mcl-1 increase. In SH, only p38MAPK inhibition decreased Mcl-1 expression. Similar to neutrophils of healthy subjects exposed to IH (0.97± 0.2), in OSA neutrophils, Bax/Mcl-1 ratio was significantly lower compared to normoxic controls (1.0±0.5 vs.1.99±0.3, p=0.015), and Bax did not co-localize with mitochondria. These findings suggest that decreased Bax/Mcl-1 balance promotes neutrophil survival in IH in-vitro as well as in OSA patients. Moreover, Bax/Mcl-1 protein function in IH and SH might be regulated by different signal transduction pathways, highlighting a novel regulatory function through ERK1/2 signaling in IH.
