This study showed that 10 men identified as Essential alcoholics had significantly lower resting systolic and diastolic blood pressures and significantly higher scores on Latcham's measure of antisocial behavior than 11 Reactive alcoholics. For all alcoholics the antisocial measure was positively correlated with the total score on the Rudie-McGaughran questionnaire. Also, the antisocial measure was negatively correlated with diastolic blood pressure and heart rate. If lower resting cardiovascular activity were a psychophysiological indicator of more antisocial behavior, change on both variables could be associated with initiation and maintenance of alcoholic drinking by Essential alcoholic men.

In this single-blind crossover study the antihypertensive efficacies of two dihydropyridine calcium antagonists, sustained-release isradipine and lacidipine, were compared using clinic and ambulatory blood-pressure measurements. After a 2-week placebo wash-out, 34 patients (19 men, 15 women, mean age 49 years) with mild to moderate hypertension (diastolic blood pressure range 95 – 110 mmHg) were treated with 5 mg sustained-release isradipine for 4 weeks and 4 mg lacidipine for 4 weeks in a random order. Medications were taken once daily at 08.00 h. Clinic and ambulatory blood pressures were recorded at the end of each placebo or treatment period. Two patients stopped isradipine and six lacidipine because of severe adverse effects. Clinic systolic and diastolic blood pressures decreased by an average of 17/14 mmHg with isradipine and 17/13 mmHg with lacidipine, compared with placebo ( P < 0.01 in both cases), without a change in heart rate. Mean ambulatory 24-h and daytime systolic and diastolic blood pressure were significantly reduced by sustained-release isradipine and lacidipine ( P < 0.05 and P < 0.01, respectively). At night systolic blood pressure fell compared with placebo ( P < 0.05 with both drugs) whereas the reduction in diastolic blood pressure was not statistically significant. Mean 24-h heart rate remained unchanged. Blood-pressure variability did not differ significantly between the two drugs or between either drug and the placebo. The antihypertensive effects of sustained-release isradipine and lacidipine were similar, but the tolerability of isradipine appears to be greater since it caused fewer withdrawals.

The Impact

Aim/Background: Delirium is common in critically ill patients. For its treatment along with other sedatives, dexmedetomidine has also been prescribed by the clinicians.  However, the outcomes with its use are less well-defined by any study in local population. We aimed to study its effectiveness for delirium and the impact on hemodynamics in critically sick patients of our population. Methodology: It was a cross-sectional, prospective observational study conducted on 212 participants after ethical review committee approval at our hospital. Heart rate, systolic and diastolic blood pressures and Richmond Agitation Sedation Scale (RASS) scores were recorded before starting dexmedetomidine and within one hour of starting the drug. More than 10% decrease in heart rate (HR) or systolic or diastolic blood pressure was considered as an impact on hemodynamic parameters. An achievement of RASS of -2 was considered as effectiveness of drug.  Results: There was a mean drop of HR by 13.78 ± 18.58 beats/min (14.49%) after starting dexmedetomidine. Mean systolic blood pressure drop was 10.99 ± 20.67 mmHg (9.16%), and mean drop in diastolic blood pressure was 4.958 ± 12.53 mmHg after dexmedetomidine use. The mean value of RASS score achieved on dexmedetomidine was -2.  Conclusion: Our study concluded the effectiveness of dexmedetomidine as light sedation for delirium. It significantly impacted on hemodynamic parameters. Its impact on heart rate was more pronounced as compared to systolic and diastolic blood pressures.

We assessed the effect of 2% lidocaine with 1:80,000 adrenaline (L + AD) and 3% prilocaine with 0.03 IU/mL felypressin (P + FP) on blood pressure and heart rate in older adults with systemic diseases undergoing dental extraction. This double-blind, randomized crossover study included 22 elderly participants, aged over 65 years. The participants were administered L + AD for one dental extraction and P + FP for the other. Blood pressure and heart rate were recorded immediately, 5, and 10 minutes after local anesthetic administration and the data were analyzed. The systolic and diastolic blood pressures in the P + FP group increased at all measurement points (p &lt; .001). In the L + AD group, the diastolic blood pressure decreased at 5 and 10 minutes after local anesthetic administration (p &lt; .05), whereas the heart rate increased at all measured time points (p &lt; .001). There were statistically significant differences in systolic blood pressure at 5 and 10 minutes after local anesthetic administration and in diastolic blood pressure and heart rate at all time points between the 2 groups. In older adults, P + FP administration increased the systolic and diastolic blood pressures. L + AD administration increased the heart rate and decreased the diastolic blood pressure.

AbstractThis study aimed to assess whether obesity and/or maximal exercise can change 24 h cardiac autonomic modulation and blood pressure in young men. Thirty-nine men (n: 20; 21.9±1.8 kg·m−2, and n: 19; 32.9±2.4 kg·m−2) were randomly assigned to perform a control (non-exercise) and an experimental day exercise (after maximal incremental test). Cardiac autonomic modulation was evaluated through frequency domain heart rate variability (HRV). Obesity did not impair the ambulatory HRV (p>0.05), however higher diastolic blood pressure during asleep time (p=0.02; group main effect) was observed. The 24 h and awake heart rate was higher on the experimental day (p<0.05; day main effect), regardless of obesity. Hypotension on the experimental day, compared to control day, was observed (p<0.05). Obesity indicators were significantly correlated with heart rate during asleep time (Rho=0.34 to 0.36) and with ambulatory blood pressure(r/Rho=0.32 to 0.53). Furthermore, the HRV threshold workload was significantly correlated with ambulatory heart rate (r/Rho=− 0.38 to−0.52). Finally, ambulatory HRV in obese young men was preserved; however, diastolic blood pressure was increased during asleep time. Maximal exercise caused heart rate increase and 24h hypotension, with decreased cardiac autonomic modulation in the first hour, regardless of obesity.

Screening Interview

This study was designed to determine if visualization of anger- and fear-provoking scenes produced differential physiological patterns similar to those produced by in vivo manipulations. Normotensive college students were selected on the basis of their responses to newly developed Anger and Fear/Anxiety questionnaires and for their ability to construct arousing scenes during a screening interview. In a 2 × 2 design (intensity × emotion), four scenes (high and low anger, high and low fear) were constructed individually for each of 16 subjects to imagine. Diastolic blood pressure, systolic blood pressure, and heart rate were monitored during visualization of each scene. Change in diastolic blood pressure was significantly greater for high anger than for high fear as predicted. Analysis of change in heart rate and systolic blood pressure showed significant effects for intensity only. These results provide further support for the concept of physiological differentiation in human emotion and suggest the utility of imagery for systematic study of human emotional responding.

Pressure Changes

1. Changes in blood pressure in the dorsal aorta, ventral aorta and subintestinal vein, as well as changes in heart rate and breathing rate during moderate swimming activity in the rainbow trout are reported. 2. Blood pressures both afferent and efferent to the gills increased during swimming and then returned to normal levels within 30 min. after exercise. 3. Venous blood pressure was characterized by periodic increases during swimming. The pressure changes were not in phase with the body movements. 4. Although total venous return to the heart increased during swimming, a decreased blood flow was recorded in the subintestinal vein. 5. Heart rate and breathing rate increased during swimming and then decreased when swimming ceased. 6. Some possible mechanisms regulating heart and breathing rates are discussed.

Pre-eclampsia is one of the fatal complications in pregnancy. Zinc plays an important role in the course and eventual outcome of human pregnancy, and is essential for normal embryogenesis and fetal growth. Zinc deficiency in pregnancy is thought to be associated with pre-eclampsia. The aim of this study was, therefore, to investigate the scum zinc level in pre-eclampsia and to examine its association (if any) with pre-eclampsia. A case control study was done among 45 pre-eclamptic and 35 normotensive pregnants at their third trimester. Serum zinc concentration was determined by Atomic Absorption Flame Spectrophotometric method. Correlative analysis was made to find any correlation, of serum zinc with blood Pressure. Results showed identical Maternal and gestational age, and different gravida distribution for the patients and controls, and significantly (P<0.005) higher blood pressures (systolic and diastolic) for pre-eclampsia. Serum zinc concentration were estimated 0.65±0.09mg/L in pre-eclamsia and 0.60±0.08mg/L in pregnant controls, difference of which was insignificant (p=0.284). Correlative analysis wowed that there was a linear correlation between serum level and diastolic blood pressure, but it was found to be insignificant (r=0.158, p=0.330). It was suggested that changes in zinc status may not be an etiological or contributory factor in pre-eclamsia.

Insight Into

The laboratory mouse is a facultative daily heterotherm in that it experiences bouts of torpor under caloric restriction. Mice are the most frequently studied laboratory mammal, and often, genetically modified mice are used to investigate many physiological functions related to weight loss and caloric intake. As such, research documenting the cardiovascular changes during fasting-induced torpor in mice is warranted. In the current study, C57BL/6 mice were implanted either with EKG/temperature telemeters or blood pressure telemeters. Upon fasting and exposure to an ambient temperature (Ta) of 19°C, mice entered torpor bouts as assessed by core body temperature (Tb). Core Tb fell from 36.6 ± 0.2°C to a minimum of 25.9 ± 0.9°C during the fast, with a concomitant fall in heart rate from 607 ± 12 beats per minute (bpm) to a minimum of 158 ± 20 bpm. Below a core Tb of 31°C, heart rate fell exponentially with Tb, and the Q10 was 2.61 ± 0.18. Further, mice implanted with blood pressure telemeters exhibited similar heart rate and activity profiles as those implanted with EKG/temperature telemeters, and the fall in heart rate and core Tb during entrance into torpor was paralleled by a fall in blood pressure. The minimum systolic, mean, and diastolic blood pressures of torpid mice were 62.3 ± 10.2, 51.9 ± 9.2, 41.0 ± 7.5 mmHg, respectively. Torpid mice had a significantly lower heart rate (25–35%) than when euthermic at mean arterial pressures from 75 to 100 mmHg, suggesting that total peripheral resistance is elevated during torpor. These data provide new and significant insight into the cardiovascular adjustments that occur in torpid mice.

Objective To identify the cardiovascular effects of long-acting methylphenidate administered for twelve weeks in Indonesian children with ADHD.Methods This was an 18-week, time series study on children with ADHD who were given 20 mg of long-acting methylphenidate for twelve weeks. During the study period we made ten serial observations of the subjects, including before, during and 6 weeks following drug administration. We included drug naive children with ADHD between the ages of 7 – 10 years. Children with mental retardation and chronic physical or mental disorders were excluded. Blood pressure was measured by sphygmomanometer with a child’s cuff at the brachial artery. We also collected data on heart rate, side effects, complaints and other medications used during the study. Repeated analysis was performed on the data with a P level of 0.05.Results Twenty-one subjects were recruited for this study. Mean blood pressure fluctuated insignificantly during the research period, for both mean systolic and mean diastolic blood pressures (P=0.115 and P=0.059). Mean heart rate also fluctuated insignificantly (P=0.091). All fluctuations were within the normal ranges. During the study, there were complaints of dizziness, nausea, and gastrointestinal upset, but they were reportedly mild and disappeared before the second week of observation.Conclusion Administration of 20 mg long-acting methylphenidate for twelve weeks in children with ADHD altered mean blood pressures and heart rates, but within the normal range for children of their age. However, cardiovascular risk observation is still needed when administering methylphenidate to children with ADHD, especially for those using the medication long-term.[Paediatr Indones. 2011;51:282-7].

Elective Cesarean

The severity of postoperative pain and hemodynamic changes during and post-cesarean section have a direct effect on the neonatal and maternal condition. This study aimed to compare pain severity, hemodynamic changes, and patient satisfaction following two anesthesia techniques in elective cesarean section. In this blinded study, 60 women who were candidate for cesarean section were allocated into two equal groups of general anesthesia (GA) and spinal anesthesia (SA). Systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and O2 Saturation at pre cesarean (T0), the uterine incision time (T1), end of surgery (T2), 6h (T3), 12h (T4), and 24 hours post-cesarean (T5) were measured. A Visual Analog Scale assessed post-cesarean pain, 6, 12, and 24 hours post-cesarean. Gender, birth weight, first- and fifth- minutes’ apgar score was recorded in the checklists. The VAS score was significantly higher in the GA group at 6h, 12h, and 24 hours post-cesarean (P=0.014, P=0.002, P=0.017, respectively). SBP and DBP at T1 in the GA group were significantly higher than in the S.A group (P<0.001). The heart rate at T0 and T1 in the GA group was lower than the SA group (P=0.001, P=0.045 respectively). The difference between the apgar scores of the two groups was not significant. SA for cesarean section was associated with lower postoperative pain, systolic and diastolic blood pressure. However, the two groups had no significant difference in terms of patients’ satisfaction and apgar scores. © 2019 Tehran University of Medical Sciences. All rights reserved.
