Dreams as a possible reflection of a dissociated self-monitoring system.

Recently, there has been a great deal of clinical and experimental interest expressed in dissociative disorders and dissociative states. Theories of mental organization and personality have been formulated as a result of this new emphasis on dissociative phenomena. Dreams may possibly be thought of as dissociative phenomena of a particular type that reflect a monitoring of and reaction to internal and external conditions within the dreamer. Experimental and/or clinical work related to hypnosis, rapid eye movement phenomena, dreams, and hemispheric specialization are discussed to support this view. Dreams are described within the context of dissociation-based theories of personality organization. Brain behavior relationships are emphasized whenever possible.

Performance of the continuous glucose monitoring system (CGMS) during development of ketosis in patients on insulin pump therapy.

AIMS: Ketoacidosis is one of the most severe complications of Type 1 diabetes. Development of ketosis leads to substantial shifts in electrolyte and ion concentrations in the different fluid compartments of the body. This study was performed to investigate the performance of the continuous glucose monitoring device (CGMS) during ketoacidosis. METHODS: Twelve patients with Type 1 diabetes using continuous subcutaneous insulin infusion (CSII) participated in this trial [10 women, two men; age (mean +/- sd) 34 +/- 9 years; disease duration 17 +/- 10 years; HbA(1c) 7.1 +/- 1.0%]. In the morning, patients ate breakfast and the insulin pump was stopped at 11.00 h and restarted after 8 h. Observation parameters during this experiment were: blood glucose (laboratory reference and CGMS), 3-hydroxy-butyrate (3-OHB), pH, Na, pCO(2), pO(2), free fatty acids, osmolarity, standard bicarbonate, and lactate. RESULTS: Blood glucose increased and reached a plateau within 2 h after pump stop (from 6.2 +/- 2.56 to 16.7 +/- 4.44 mmol/l, P < 0.001). A constant increase in 3-OHB (from 0.0 to 0.8 +/- 0.5 mmol/l, P < 0.001) and decrease in pH (from 7.43 +/- 0.02 to 7.40 +/- 0.03, P < 0.05) indicated ketosis development. Na decreased from 141 +/- 1.4 to 138 +/- 2.8 mmol/l, P < 0.001). Free fatty acids increased from 0.577 +/- 0.330 to 1.330 +/- 0.462 mmol/l (P < 0.001). The CGMS values showed excellent agreement with the capillary blood laboratory method during the entire experiment, and a modified error grid analysis revealed that 99.5% of the values were in the clinically acceptable zones A and B. CONCLUSION: The CGMS device was confirmed to be reliable and accurate during the development of hyperglycaemia and ketotic conditions.

Biological indicators and monitoring systems for validation and cycle control of sterilization processes.

The article is divided in four parts. The first part deals with terms and definitions. After that there is given a description of the most common types of biological indicators. These two parts furnish material and introduce to the third part, a survey of the components of monitors, their functions and the criteria one has to take into consideration when designing them. The fourth and last part deals with the most essential feature of biological indicators, the resistance, its calibration, description and adjustment.

Evaluation of the bedside glucose monitoring system in neonatal units.

OBJECTIVE: To evaluate the performance of a commercial reader compared with a laboratory method in neonates with a variety of diseases and conditions. PATIENTS AND METHOD: A total of 175 patients were included in the present study. Venous whole blood samples were analyzed with a commercial reader by trained nurse. Through the same sampling site, specimens were collected, spun and plasma were sent to the laboratory for measurement of plasma glucose. RESULTS: The regression analysis between the results of a commercial reader and laboratory glucose were significantly correlated (r = 0.97; p < 0.001) with the result as follows: A commercial reader = Laboratory glucose - 0.17 (n = 175). A positive slope of 0.04 was found between hematocrit and difference between a commercial reader and laboratory plasma glucose. However, this correlation was of little clinical significance. CONCLUSIONS: A commercial reader showed a good correlation with the standard laboratory method for the measurement of plasma glucose in neonates with a variety of diseases and conditions.

Validation of a new whole blood coagulation monitoring system.

The Hemochron Response is a third generation point-of-care (POC) whole blood coagulation analyzer that retains the clinical utility of the Hemochron standard (801/8000) while providing a data management program that assists the POC coordinator with Quality Assurance (QA) compliance. Clinical and laboratory studies were performed to ensure consistency of the target anticoagulation times with the Hemochron standard and to evaluate precision and reproducibility of the Hemochron Response. Clinical tests for prothrombin time (PT) using fresh and citrated whole blood, activated clotting time (ACT), and activated partial thromboplastin time (APTT) showed excellent correlation to the Hemochron standard where r = 0.929, r = 0.969, r = 0.947, and r = 0.992, respectively. This was confirmed by a paired Student's t-test. The standard expectation for reproducibility of ACT tests has been a coefficient of variation (CV) of 10%. Laboratory studies of reproducibility and precision for the Response instrument included analysis of the CV using ACT test tubes. For normal and abnormal control plasma (CPL), the range of CVs observed was 3.3%-4.6% and 3.0%-5.0%, respectively. For heparin dose response analysis, the range for Donor 1 and 2 was 1.0%-4.2% and 1.1%-8.0%, respectively. These data suggest that the Hemochron Response is reliable and equivalent to the Hemochron standard in clinical applications.

Influence of caffeine on frequency of hypoglycemia detected by continuous interstitial glucose monitoring system in patients with long-standing type 1 diabetes.

OBJECTIVE: The aim of this study was to investigate the effect of caffeine (in doses equivalent to normal daily ingestion) on rates and severity of hypoglycemia in patients with long-standing type 1 diabetes to determine the relationship between caffeine, autonomic function, and hypoglycemia. RESEARCH DESIGN AND METHODS: Using a double-blinded randomized study, we investigated the effect of caffeine versus placebo in 19 patients with long-standing type 1 diabetes using continuous glucose sensing technology and simultaneous assessment of autonomic function using Holter monitoring. RESULTS: Caffeine reduced the duration of nocturnal hypoglycemia with a mean duration of 49 minutes (range 0-235) versus 132 (0-468) minutes (P = 0.035). The reduction in duration of nighttime hypoglycemia was due to a decline in the number of episodes of moderate hypoglycemia at the expense of mild hypoglycemic episodes (P = 0.04). There was no overall correlation between reduced heart rate variability (a marker of autonomic dysfunction) and hypoglycemic events (r(s) = 0.12, P = 0.62). CONCLUSIONS: Our results suggest that caffeine is associated with a significant reduction in nocturnal hypoglycemia. The reduction in nocturnal hypoglycemia was not linked to the concomitant rise in parasympathetic activity associated with caffeine.
