A methodologically comprehensive approach to blood pressure 24-hour pattern in essential obesity
No full textAbstract
This study deals with the non-invasive ambulatory monitoring of blood pressure (BP) in obese patients. The individual data were analyzed by means of chronobiometric procedures which allow us to estimate the BP values in their within-day discrete variability, circadian rhythmicity and daily pressure load (Daily Baric Impact). The estimates of time-qualified values documented that both male and female obese patients show an elevation of BP values all over the 24-h span. The cosine function revealed that the BP circadian rhythm in obese males and females is preserved but shows a higher level of oscillation. The measure of the area under this oscillation (aesor) provided evidence that the Daily Baric Impact is higher in obese patients as compared to non-obese subjects. The spectral analysis, in turn, revealed that the BP 24-h variability in obese patients is sustained by oscillatory components which are not detectable in the physiologic spectrum of resolution in harmonics, suggesting an abnormal tone in regulatory mechanisms. The relation of the Daily Baric Impact to the body surface (Baric Index) demonstrated that the increase in BP values in obesity is a phenomenon which is secondary to the overweight

Endoscope washers - a protocol for their use
No full textA protocol for the disinfection of gastroduodenoscopes, retrograde cholangiopancreatography endoscopes and colonoscopes using endoscope washers is described. The process recommends initial manual washing with a disinfectant containing didecyldimethylammonium chloride, surfactants and enzymes, a second washing in the endoscope washer using a detergent associated with a bacteriostatic, fungistatic substance (benzoisothiazolone) and finally the use of a 2% glutaraldehyde product buffered at pH6. After treatment with 2% Steranios added to the washer, less than 1 micro-organism/ml liquid was found in the following units: 83% of the colonoscopes, 83% of the oesophagogastroduodenoscopes, 83% of the main channels of the retrograde cholangiopancreatography endoscopes and 75% of the auxiliary channels of the latter instruments. In 14% of the colonoscopes, 42% of the gastroduodenoscopes, 42% of the main and 50% of auxiliary channels in the retrograde cholangiopancreatography endoscopes there were no signs of microbial growth in the wash liquid. The results obtained indicated that this protocol allowed adequate disinfection of the endoscope channels, structurally the most difficult part of the instrument to disinfect. Emphasis is given to the degree by which instrument contamination can increase during overnight storage, suggesting that endoscopes need to be submitted to further disinfection after overnight storage. Moreover, the water flowing into the washers can also cause instrument recontamination, particularly during the final rinses. Therefore, to better safeguard the health of patients undergoing endoscopy, special care must be taken to maintain the filters and disinfect the washers themselves, no matter how effective the disinfection protocol used may be.
