“…In addition, the level of stress can be also measured by simply taking saliva samples from athletes while they compete in sports games 3 . However, it is known that while blood catecholamines do not reflect the concentration of salivary catecholamines, salivary alpha amylase (sAA) reflects blood catecholamines 4 - 7 . Indeed, sAA secreted into the saliva to digest starch increases when sympathetic nerves are activated during physical and mental stress situations 8 , 9 .…”

[Purpose]This study was aimed to investigate the relationship between psychological and physiological changes and performance in archery, which is strongly influenced by psychological factors including concentration, tension, anxiety, and stress.[Methods]A total of 19 athletes from women’s colleges who participated in the 30 m individual competition at the 34th President’s Cup National Archery Competition in July 2016 were included in this study. The anxiety levels of the participants were assessed on a 10-point Likert scale, with 1 corresponding to “not at all” and 10 to “extremely anxious.” Saliva samples were collected as follows: 10 min before the game (pre-10), 1 min before the game (pre-1), and 10 min after the game (post-10). Repeated measures general linear model ANOVA was performed to compare the mean values of salivary alpha amylase (sAA) concentrations and anxiety levels. The correlations between sAA, anxiety, and game records were analyzed using the Pearson’s correlation method.[Results]The sAA concentrations increased significantly in pre-1 and post-10, but not in pre-10 samples. Moreover, anxiety levels increased in both pre-1 and post-10 samples, but not in pre-10 samples. Anxiety and sAA were positively correlated (p < 0.01), while sAA and game records, or anxiety and game record were negatively correlated (p < 0.01).[Conclusion]During the archery competition, the level of cognitive anxiety increased, sAA concentrations increased, and performance decreased. The study findings suggest that during archery competitions, anxiety hinders performance, and this effect may be related to the increase in sAA levels.

“…Salivary alpha-amylase activity (sAA) and plasma noradrenaline (NA) concentrations are often considered to be surrogate markers of sympathetic activation in response to stress. sAA is a non invasive marker for stress of sympathetic activation [13] . Literature shows that there is an association between changes in Salivary Amylase(SA) during exposure to a stressful stimulus and changes in blood norepinephrine or heart rate variability indices strongly suggests that SA is an accurate marker of sympathetic nervous system activity.…”

Over the last decade, Saliva is being chosen as an alternative to blood and urine. Whole saliva contains mixture of secretions. Saliva is usually deposited in bite marks found in many homicides, assault and other criminal cases. Saliva is often detected in the crime scene along with bite marks or lip prints where the oral cavity may have been involved. Cellular and serological analysis of the obtained saliva is of immense use in identification of the accused. One such component of saliva is Amylase testing. It has been used as a presumptive test for crime scene. Neurodevelopmental disorders (NDDs) are multifaceted conditions characterized by impairments. People with NDD are overrepresented in criminal populations and evaluating them for criminal responsibility can often be a complex task for forensic examiners. Salivary Amylase can be used as a tool to evaluate the mental health of the offender.

Background: The diagnosis and the treatment for cancer are significant stressors for the patients. It can affect physical as well as psychological well-being. Variations in salivary amylase indicate physiological responses to the stressful experience during chemotherapy. Music therapy is witnessed to decrease psychosocial distress in the oncology setting. Listening to music can positively benefit neurophysiologic and emotional responses as well as promote relaxation, especially beneficial for cancer patients undergoing painful and anxiety-inducing chemotherapy. It is, therefore nurses, who are so familiar with this environment, not only to be aware of this anxiety-producing process but to cope with it and to alleviate it for the patient as much as possible. Objective: The objective of the study was to determine the salivary amylase levels in patients undergoing chemotherapy before and after listening to preferred music. Design: Quasi-experimental repeated measure design. Setting; Experimental and control group were recruited from two oncology units of selected multispecialty hospitals. Participants: Purposive sampling techniques were used to select the study participants. Patients of age group eighteen and above, undergoing first time chemotherapy treatment and the chemotherapy infusion lasts for minimum of 3 hours duration was the inclusion criteria whereas Patients who were unable to listen to music due to hearing problems, those who were with head and neck cancer, diabetes, hypertension, and thyroid problems were excluded from the study. 168 eligible participants were recruited among which 8 were unable to continue. Methods: Saliva was collected from both the study groups before and after the chemotherapy administration. The patient preferred instrumental music intervention was administered for the duration of 3 hours during chemotherapy with the help of mp3 player and musical pillow in the experimental group where the control group had a routine oncology unit care and they were rested on a bed during the chemotherapy administration. The post-tests were done on day 3 and day 5. Results: Significant changes in mean salivary amylase were observed in the experimental group compared to the control group (p˂0.05). Repeated measure ANOVA also showed a significant difference (p˂0.05) in the experimental group at different time points of observation. There was a significant association between the baseline amylase level and stage of cancer in both the experimental and control group (p˂0.05). Conclusion: Music was effective in patients undergoing chemotherapy in terms of reduction in salivary amylase level.
