Ancient Times

From ancient times, firefighter’s faces a high risk of burns which may sometimes lead to death, especially those who enter the burning building first and those who are holding the front end of the nozzle. In order to avoid this kind of risk, an enlightened physical admonition arrangement for firefighter was put forward. Corresponding controller is developed with low power consumption on the display screen terminator which could inspect numerous conflagration in the surroundings and the site where firefighter reside as substantially as their critical bodily data so that the admonition might be provided with a low transmitting error rate. Moreover, the suitable information processing computation is sorted out to assure the preciseness. Consequently, competent firefighter’s individual protection is augmented considerably with strong anti-interference. In addition to this, a buzzer will be there on the side of firefighter like alarm when parameters like temperature, blood pressure, heart rate becomes abnormal so that they might not take the risk considering their body conditions.

Background. Acquired AVF in pediatrics are commonly caused by iatrogenic means, including arterial or venous punctures. These fistulae can cause great hemodynamic stress on the heart as soon as they are created.Case. A six-month-old 25-week gestation infant was referred for respiratory distress. Initial exam revealed tachypnea, tachycardia, and hypertension. There was a bruit noted on her left arm. An ultrasound showed an arteriovenous fistula. Its location, however, precluded intervention because of the high risk for limb-loss. An echocardiogram showed evidence of pulmonary hypertension that was treated with sildenafil and furosemide. However, no improvement was seen. On temporary manual occlusion of the fistula, the patient was noted to have increased her blood pressure and decreased her heart rate, suggesting significant hemodynamic effect of the fistula. The fistula was subsequently ligated and the patient clinically and echocardiographically improved.Conclusion. A patient in high output cardiac failure or pulmonary artery hypertension, especially prematüre patients with preexisting lung disease, should be probed for history of multiple punctures, trauma, or surgery and should have prompt evaluation for AVF. If it can be diagnosed and repaired, most of the cases have been shown to decrease the stress on the heart and reverse the pathologic hemodynamics.

Autonomic Activity

Background: Studies have reported that reduced autonomic nervous system activity could result in a suboptimal health condition and various diseases, further increasing the mortality rate. The present study aimed to determine the difference in risk factors for metabolic and cardiovascular diseases in patients with reduced or unstable autonomic activity according to heart rate variability test results.Methods: We recorded blood pressure, physical measurements (body mass index and waist circumference), fasting blood glucose, and blood lipid status. Indicators representative of autonomic nerve functionality (total power [TP], standard deviation of the normal-to-normal intervals [SDNN], low-frequency band [LF], high-frequency band [HF]) were measured using a 5-minute heart rate variability test. Each indicator was divided into quartiles.Results: In men, the risk of abdominal obesity was high in the group with a low TP. In the group with a low SDNN, TP, and LF, the risk of a blood pressure increase was high. When LH and HF were low, there was a high risk of increased fasting blood sugar, whereas when LH was low, there was a high risk of hypertriglyceridemia. Women with SDNN loss had higher odds ratios for abdominal obesity and low high-density lipoprotein cholesterolemia.Conclusions: These results indicate a higher risk of having risk factors for metabolic and cardiovascular diseases, such as abdominal obesity, elevated blood pressure, hyperglycemia, hypertriglyceridemia, and low high-density lipoprotein cholesterolemia in a group with reduced autonomic activity measured by heart rate variability. Women with a low SDNN had a 4.51-fold higher risk of abdominal obesity than women with a high SDNN, showing the greatest value of the heart rate variability indices.

Abstract. Caffeine placebo expectation seems to improve vigilance and cognitive performance. This study investigated the effect of caffeine and placebo expectation on vigilance and cognitive performance during 28 h sleep deprivation. Ten healthy males volunteered to take part in the double-blind, cross-over study, which required participants to complete five treatment periods of 28 h separated by 1-week wash-out intervals. The treatments were no substance (Control); caffeine 200 mg at 00:00 (C200); placebo 200 mg at 00:00 (P200); twice caffeine 200 mg at 00:00 and 04:00 (C200-C200); caffeine 200 mg at 00:00 and placebo 200 mg at 04:00 (C200-P200). Participants were told that all capsules were caffeine and given information about the effects of caffeine to increase expectation. Vigilance was assessed by a three-letter cancellation test, cognitive functions by the continuous addition test and Stroop test, and cardiovascular regulation by heart rate and blood pressure. Tests were performed bihourly from 00:00 to 10:00 of the second day. Results indicated that C200-P200 and C200-C200 were more alert (p < .05) than Control and P200. Their cognitive functions were higher (p < .05) than Control and P200. Also, C200-P200 scored higher than C200 in the letter cancellation task (p < .05). No test showed any significant differences between C200-P200 and C200-C200. The results demonstrated that the combination of caffeine 200 mg and placebo 200 mg expectation exerted prolonged positive effects on vigilance and cognitive performance.

Present Trial

Recent studies have revealed evidence for increased pain sensitivity in individuals with chronically low blood pressure. The present trial explored whether pain sensitivity can be reduced by pharmacological elevation of blood pressure. Effects of the sympathomimetic midodrine on threshold and tolerance to heat pain were examined in 52 hypotensive persons (mean blood pressure 96/61 mmHg) based on a randomized, placebo-controlled, double-blind design. Heat stimuli were applied to the forearm via a contact thermode. Confounding of drug effects on pain perception with changes in skin temperature, temperature sensitivity, and mood were statistically controlled for. Compared to placebo, higher pain threshold and tolerance, increased blood pressure, as well as reduced heart rate were observed under the sympathomimetic condition. Increases in systolic blood pressure between points of measurement correlated positively with increases in pain threshold and tolerance, and decreases in heart rate were associated with increases in pain threshold. The findings underline the causal role of hypotension in the augmented pain sensitivity related to this condition. Pain reduction as a function of heart rate decrease suggests involvement of a baroreceptor-related mechanism in the pain attrition. The increased proneness of persons with chronic hypotension toward clinical pain is discussed.
