✓ The authors report a method for measuring total local brain tissue pressure (BTP) using a miniature catheter transducer stereotaxically introduced into the white matter of the cat's cerebrum. Quantitative rapid phasic pressure changes were satisfactorily demonstrated. Due to some drift of baseline of the transducers and inability to perform in vivo calibration, reliable long-term quantitative pressure measurements sometimes could not be studied. The BTP from each cerebral hemisphere and the cisternal pressure (CP) were monitored during alterations of pCO2 and systemic blood pressure, and distilled H2O injection prior to and after right middle cerebral artery (MCA) ligation. The catheter transducers functioned well on chronic implantation for up to 6 weeks. Compared to the chronically implanted catheters, acutely implanted catheters responded identically except for drift. The response of intracranial pressure and CP to MCA occlusion, alterations in pCO2, and systemic blood pressure were similar. No BTP gradients appeared in response to MCA ligation, hypercapnia, hypertension, or progressive swelling of the resulting infarction.

Background We investigated daily blood pressure (BP) changes during fasting periods ranging from 4 to 41 (10.0±3.8) days in a cohort of 1610 subjects, including 920 normotensive, 313 hypertensive nonmedicated, and 377 hypertensive medicated individuals. Methods and Results Subjects underwent a multidisciplinary fasting program with a daily intake of ≈250 kcal. Weight and stress scores decreased during fasting, and the well‐being index increased, documenting a good tolerability. BP mean values decreased from 126.2±18.6/81.4±11.0 to 119.7±15.9/77.6±9.8 mm Hg (mean change, −6.5/3.8 mm Hg). BP changes were larger for hypertensive nonmedicated subjects (>140/90 mm Hg) and reduced by 16.7/8.8 mm Hg. This reduction reached 24.7/13.1 mm Hg for hypertensive nonmedicated subjects (n=76) with the highest BP (>160/100 mm Hg). In the normotensive group, BP decreased moderately by 3.0/1.9 mm Hg. Interestingly, we documented an increase of 6.3/2.2 mm Hg in a subgroup of 69 female subjects with BP <100/60 mm Hg. In the hypertensive medicated group, although BP decreased from 134.6/86.0 to 127.3/81.3 mm Hg, medication was stopped in 23.6% of the subjects, whereas dosage was reduced in 43.5% and remained unchanged in 19.4%. The decrease in BP was larger in subjects fasting longer. Baseline metabolic parameters, such as body mass index and glucose levels, as well as age, can be used to predict the amplitude of the BP decrease during fasting with a machine learning model. Conclusions Long‐term fasting tends to decrease BP in subjects with elevated BP values. This effect persisted during the 4 days of stepwise food reintroduction, even when subjects stopped their antihypertensive medication.
