<p class="Abstract">Physiological or biological stress is an organism’s response to a stressor such as an environmental condition or a stimulus. The identification of physiological stress while performing the activities of daily living is an important field of health research in preventive medicine. Activities initiate a dynamic physiological response that can be used as an indicator of the overall health status. This is especially relevant to high risk groups; the assessment of the physical state of patients with cardiovascular diseases in daily activities is still very difficult. This paper presents a context-aware telemonitoring platform, IPM-mHealth, that receives vital parameters from multiple sensors for online, real-time analysis. IPM-mHealth provides the technical basis for effectively evaluating patients’ physiological conditions, whether inpatient or at home, through the relevance between physical function and daily activities. The two core modules in the platform include: 1) online activity recognition algorithms based on 3-axis acceleration sensors and 2) a knowledge-based, conditional-reasoning decision module which uses context information to improve the accuracy of determining the occurrence of a potentially dangerous abnormal heart rate. Finally, we present relevant experiments to collect cardiac information and upper-body acceleration data from the human subjects. The test results show that this platform has enormous potential for use in long-term health observation, and can help us define an optimal patient activity profile through the automatic activity analysis.</p>

Shoulder Score

Introduction. Indications for the use of partial shoulder prosthesis are dislocated four-part fractures and multi-part and four-part fractures-dislocations, impressive fractures of the humeral head (including involvement of more than 40% of the articular surface) and ?head splitting? fractures of humerus. The aim of this study was to present the results of the application of partial shoulder prosthesis at the Department of Orthopedic Surgery and Traumatology, Clinical Center of Vojvodina in Novi Sad and identify risk groups among the participants. Material and Methods. The study, which was retrospective, included 22 patients who had undergone the partial shoulder arthroplasty in the period from 2005 to 2015 at the Department of Orthopedic Surgery and Traumatology, Clinical Center of Vojvodina. The functional results were evaluated on the basis of the Constant Shoulder Score. Results. The study sample consisted of 15 women and 7 men, whose mean age was 64.9 ? 9.1 years. The average time from the injury to surgery was 13.3 days. According to the Constant scoring scale, the result was excellent in 6 (27%) patients, good in 3 (14%), fair in 7 (32%), and poor in 6 (27%) participants. 75% of participants said they were satisfied with the results of the operation. Conclusion. Partial shoulder prosthesis gives good functional results and allows resumption of activities of daily living. Better results were obtained within the subjective segments (pain, daily activities, vitality), which points out a greater subjective patient?s satisfaction in relation to the measured functio?nal outcome.

Background: The aim of this study was to evaluate the effects of 72-h sleep deprivation on normal daily activities (work, family, and sports), and to investigate whether sleep can be chronically reduced without dangerous consequences. Methods: The participant in this study was an adult male (age 41 years; mass 69 kg; height 173 cm). During the 72 h, data were collected every 6 h, involving a baseline (pre-deprivation). We monitored various parameters: Oxidative Stress (D-Rom and Bap test), Psychological Responses (test POMS and Measure of Global Stress), Metabolic expenditure (kJ) using a metabolic holter, EEG records, Cortisol, and Catecholamines level. Results: An interesting result was observed in the post-test phase, when a brief moment of deep sleep and total absence of a very deep sleep occurred, while an almost normal condition occurred in the pre-test sleep. Conclusion: During the 72-h sleep deprivation, no psycho-physiological stress was recorded. The participant has remained within the threshold of well-being. Only a peak was recorded during the 66th hour, but it was within the wellness threshold.

OBJECTIVES: For violinists, it is common practice to play while standing or sitting. When playing in an orchestra, generally two persons share one music stand, with one sitting to the right and the other to the left of the stand. The present study investigated specific movement patterns while playing in these different positions. METHODS: Using a posturographic device and 3D motion capture, the body weight distributions and specific body movements of 19 violinists were analyzed. RESULTS: Results showed unbalanced weight distributions while sitting in front of or oriented to the right of the music stand compared to the almost even distributions while standing or oriented to the left of the stand. Analyses of movement patterns showed significant differences between standing and sitting, mainly in the upper body parts with less movability while sitting. While sitting in front of or oriented to the right of the music stand, the right bowing arm showed more restricted movements compared to other positions. CONCLUSION: The playing positions are discussed with regard to possible physiological stress and health risks. The study emphasizes the importance of different playing positions and offers starting points for discussion of postural influences and sensible handling of the instrument in performance and practice for violinists.

Danforth and colleagues report on demography, diet, mitochondrial DNA, and biological stress in remains from Moran, Mississippi, part of New Biloxi, a French colonial settlement. This study is unique, since at the time of this writing, skeletal remains were identified at only six French sites in the U.S. These authors test whether the historically documented policies implemented under “Code Noir” were actually practiced and enforced at the settlement, segregating the European settlers, enslaved Africans and their descendants, and Native Americans. The authors were surprised by the high number of young males of European ancestry they encountered. Stable isotope data indicated that their diets were dominated by C3 based plants and only one had C4 based diet. Although the human remains were small and few possessed high levels of enamel defects, Danforth and colleagues found low levels of physiological stress. They conclude that either the burials from Moran were not part of New Biloxi and did not suffer to the degree the settlers of New Biloxi suffered or there was strict enforcement of segregation, with the remains of other groups interred elsewhere, and the conditions were not as poor for the Moran group as historical documents about New Biloxi say.

AbstractIn recent years, research in behavioral medicine has become increasingly focused on understanding how chronic and acute exposure to stress impacts health outcomes. During stress, the body’s physiological stress systems are activated. These systems closely interact with the immune system and are, thus, importantly implicated in the onset and maintenance of disease states. While much of the research in behavioral medicine that has investigated the effects of stress on disease has focused on the role of the hypothalamic-pituitary-adrenal axis and its downstream biomarker, cortisol, it is evident that the autonomic nervous system (ANS) also plays a crucial role in both the biological stress process and the manifestation and maintenance of stress-related symptoms. In recent years salivary alpha-amylase (sAA) has emerged as a valid and reliable marker of ANS activity in stress research and is therefore an important biomarker to consider in behavioral medicine. In this commentary, we will highlight research relevant for behavioral medicine that has utilized sAA measurements, both basally, and in response to stress, to examine ANS function in clinical populations. We will additionally summarize findings from studies that have examined the effects of various targeted interventions on changes in sAA levels. Through this, our aim is to present evidence that sAA can serve as a feasible biomarker of ANS (dys)function in health and disease. To this end, we will also highlight important methodological considerations for readers to keep in mind when including sAA assessments in their own studies. The overarching goal of this brief commentary is to highlight how a multidimensional approach toward physiological stress measurement can allow researchers to develop a better understanding of physical health and disease states.

1. Although a pause in respiration during swallowing is a feature common to all mammals, inhibition usually occurs during expiration in adult humans and during inspiration in most other species. We tested the hypothesis that this difference is due, at least in part, to the position of the body while feeding. 2. The coordination of respiration and swallowing was studied in adult human subjects in two body positions; upright, which is typically human, and on hands and knees, which is similar to the feeding posture of most other animal species. 3. Our major finding was that the respiratory phase in which swallowing occurred was significantly related to posture. Swallows tended to occur late in the expiratory phase while feeding upright, but during early expiration while on all fours. 4. We speculate that the phase of respiration in which swallowing occurs changes with posture to compensate for the alterations in the mechanical properties of the upper body.
