The purpose of this study was to investigate the relation between watching the news and activation of the autonomic nervous system. A questionnaire was completed, and a saliva sample was collected from each of 33 participants before and after viewing a news and then a comedy clip. After exposure to the news, cortisol levels did not increase; participants reported a significant decrease in joy and an increase in restlessness. Participants reported a significant decrease in tiredness, sadness, irritation, anxiety, and restlessness, and an increase in relaxation and joy after exposure to the comedy clip. Higher rates of reported stress in the past month were associated with significantly higher rates of reported feeling cold, trembling, close to tears, sweaty palms, difficulty breathing, and restlessness. The implications of the study and directions for research are discussed.

Two children and their father, currently under investigation, have displayed paroxysmal symptoms which include a rash, angioneurotic edema, severe symptoms from the gastrointestinal and urinary tracts and other evidences of dysfunction of the autonomic nervous system. Attempts at medicinal therapy failed to ameliorate the attacks. A striking hereditary pattern is present suggesting a simple dominant type of inheritance. Emotional factors have been found to be capable of precipitating these paroxysms which have many features in common with paroxysmal disorders described in the literature under the terms periodic peritonitis, cyclic vomiting, hereditary angioneurotic edema and "periodic disease." It is important that careful evaluation of hereditary and emotional factors be made in all patients exhibiting recurrent symptoms of unexplained etiology. Psychiatric study and psychotherapy may offer a means to alleviate the symptoms in some of these patients.

The ability to maintain and respond to challenges to homeostasis is primarily a function of the autonomic nervous system (ANS). In infants with complex congenital heart defects this ability may be impaired. This study described change in ANS function before and after surgical correction in infants with transposition of the great arteries (TGA) and in healthy infants. A total of 15 newborn infants with TGA were matched with 16 healthy infants on age, gender, and feeding type. The ANS function was measured using heart rate variability (HRV). Data were collected preoperatively in the 1st week of life and postoperatively before, during, and after feeding at 2 weeks and 2 months of age. Infants with TGA demonstrated significantly lower high-frequency and low-frequency HRV preoperatively ( p < .001) when compared with healthy infants. At 2 weeks, infants with TGA were less likely than healthy infants to demonstrate adaptive changes in high-frequency HRV during feeding (Wald Z = 2.002, p = .045), and at 2 months, 40% of TGA infants exhibited delayed postfeeding recovery. Further research is needed to more thoroughly describe mechanisms of a physiologically adaptive response to feeding and to develop nursing interventions supportive of these high-risk infants.

Objective:To analyze the consequences on heart rate variability (HRV) of a hospitalization period due to surgery of the knee in sportsmen.Patients:Ten soccer players who had undergone knee surgery took part in this study.Design:HRV was measured before and after hospitalization within a 7-day interval.Results:After the hospitalization phase, heart rate at rest increased significantly (3 beats/minute). A significant decrease of 7% in the cardiac inter beat interval (R-R interval), P < 0.05 and a 66% decrease in total power spectral density: −66%, P < 0.05 were observed. The disturbance of the autonomic nervous system could be due to a variation in cardiac vagal activity resulting in a 64% decrease in the high frequencies (P < 0.05). This variation was not associated with a modification in normalized markers (LFn.u., HFn.u.) and LF/HF ratio (P > 0.05).Conclusion:In sportsmen, a hospitalization period led to an increase in resting heart rate and was associated with a disturbance of the autonomic nervous system.
