Abstract
BACKGROUND The anatomy dissection course is a major part of the first two years of the traditional medical curriculum in Germany. The vast amount of content to be learned and the repeated examination is unanimously perceived by students and teachers as a major stress factor that contributes to the increase of psychosocial stress during the first two years of the course of study. Published interventions for specific stress reduction are scarce. METHODS In a randomized, controlled design two intervention groups were compared with a control group (CG) over the whole dissection course (nine measuring points before, during and after first and second semester). The 'Stress Management intervention (IVSM)' targeted at the setting of personal standards, the 'Friendly Feedback intervention (IVFF)' at the context of frequent testing. Quantitative surveys were distributed at nine measuring points. The questionnaire comprised validated instruments and self-developed items regarding stress, positive and negative affect, anxiety, intrinsic and extrinsic motivation, self-efficacy, and perceived performance. RESULTS Out of 195 students inscribed in the dissection course, 166 (85%) agreed to participate in the study. The experience of stress during the dissection course was significantly higher in the CG than in the IVFF. Anxiety and negative affect were lower in students of the IVFF while positive affect, intrinsic motivation, and self-efficacy were higher than in the CG. For anxiety and negative affect in the IVSM this was especially seen at the end of the second semester. The self-perceived increase in both knowledge and preparedness for the first big oral and written examination did not differ between the study groups. About three quarters of the participants would choose the intervention 'Friendly Feedback' if given the choice. CONCLUSIONS Replacing formal tests with friendly feedback has proven to be an effective measure to reduce stress and negative affect and foster positive affect, self-efficacy, and intrinsic motivation, while it did not impair self-perceived academic performance.

Abstract
OBJECTIVES Rheumatoid arthritis (RA) is an autoimmune disease characterized by progressive joint destruction. Early diagnosis and treatment, before joint deformation or destruction occurs, are crucial. Identifying novel biomarkers for RA in saliva could potentially enable early detection of the disease, prior to its onset. METHODS We conducted a comprehensive proteomic analysis of salivary proteins in a mouse model of RA. Proteins were identified using western blotting and enzyme-linked immunosorbent assay in the serum, saliva, and ankle joints of DBA/1JJmsSlc mice, a model of RA. Ankle joints and submandibular glands were stained with hematoxylin and eosin and immunostained, and the results were compared with those of control mice. RESULTS Citrullinated alpha-1 antitrypsin (A1AT, 46 kDa) was commonly detected in the saliva, serum, and ankle joints of mice with severe RA and was confirmed through proteomic analysis. Western blotting showed a band corresponding to 46 kDa in the serum, saliva, and ankle joints. Immunostaining of the ankle joints with the A1AT antibody showed a strong positive signal in the synovium. CONCLUSIONS In DBA/1JJmsSlc mice, cyclic citrullinated peptide antibodies and A1AT may be involved in citrullination and contribute to the development and severity of RA, making them valuable treatment targets requiring further study.

Total Antioxidant Capacity of Saliva and Its Correlation with pH Levels among Dental Students under Different Stressful Conditions. Diagnostics (Basel) 2023; 13:3648. [PMID: 38132232 PMCID: PMC10743087 DOI: 10.3390/diagnostics13243648] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 12/08/2023] [Accepted: 12/11/2023] [Indexed: 12/23/2023] Open
Abstract
(1) Background: This cross-sectional study conducted at the Faculty of Dental Medicine, Timisoara, Romania, between December 2022 and February 2023 aims to assess salivary total antioxidant capacity and pH levels in dental students experiencing non-stressful and stressful situations and explore potential correlations between these factors. (2) Methods: Saliva samples were collected during two different periods: before an Oral Health course and before the Oral Health exam, under stressful conditions. Ethical principles were followed, and informed consent was obtained. Data on age, gender, health status, drug use, smoking habits, and anxiety levels were recorded. Saliva was collected using the draining method and pH was measured using indicator paper strips. Total antioxidant capacity (TAC) was determined using a commercial assay kit. Statistical analysis involved descriptive statistics, Student's t-test to compare pH and TAC between study groups, and Pearson's correlation coefficient to analyze the correlation between salivary pH and TAC within each group, with p < 0.05 indicating significance. (3) Results: This study involved 80 participants, comprising 26 males and 54 females, all enrolled in the 5th year of the Oral Health course, with ages ranging from 20 to 53 and a mean age of 23.62 (±4.19) years. Pearson's correlation results show a statistically significant negative relationship between the STAI test and TAC during the stress-free period (-0.02 **, N = 80, p < 0.01). (4) Conclusions: There are variations in saliva's antioxidant capacity in response to different stress conditions. Dental students experienced a higher level of stress before academic assessments compared to the non-stress period during the course.

Abstract
Fully integrated wearable sensors are capable of dynamically, directly, and independently tracking biomarkers in raw noninvasive biofluids without any other equipment or accessories by integrating the unique on-body monitoring feature with the special complete functional implementation attribute. Sweat, saliva, and urine are three important noninvasive biofluids, and changes in their biomarkers hold great potential for revealing physiological conditions. However, it is still a challenge to design single fully integrated wearable sensor arrays (FIWSAs) that are universally able to concurrently measure electrolytes and metabolites in three of the most common noninvasive biofluids including sweat, saliva, and urine. Here, we propose the first single universal FIWSAs for wirelessly, noninvasively, and simultaneously measuring various metabolites (i.e., uric acid) and electrolytes (i.e., Na+ and H+) in raw sweat, saliva, or urine under subjects' exercise by integrating the specifically designed microfluidic, sensing, and electronic modules in a seamless manner. We evaluate its utility for noninvasive gout management in healthy subjects and in gout patients through a purine-rich meal challenge and with a medicine-treatment control, respectively. Noninvasive monitoring of multiple electrolytes and metabolites in a variety of raw noninvasive biofluids via such single universal FIWSAs may enrich the understanding of the biomarkers' levels in the body and would also facilitate self-health management.

Biosens Bioelectron 2023; 222:114955. [PMID: 36462430 DOI: 10.1016/j.bios.2022.114955] [Citation(s) in RCA: 27] [Impact Index Per Article: 27.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 11/19/2022] [Accepted: 11/24/2022] [Indexed: 11/27/2022]
Abstract
Microneedle-based wearable sensors offer an alternative approach to traditional invasive blood-based health monitoring and disease diagnostics techniques. Instead of blood, microneedle-based sensors target the skin interstitial fluid (ISF), in which the biomarker type and concentration profile resemble the one found in the blood. However, unlike blood, interstitial fluid does not have the same pH-buffering capacity causing deviation of pH levels from the physiological range. Information about the skin ISF pH levels can be used as a biomarker for a wide range of pathophysiological conditions and as a marker for the calibration of a wearable sensor. The ISF pH can significantly affect the detection accuracy of other biomarkers as it influences enzyme activity, aptamer affinity, and antibody-antigen interaction. Herein, we report the fabrication of a high-density polymeric microneedle array-based (PMNA) sensing patch and its optimization for the potentiometric transdermal monitoring of pH levels in ISF. The wearable sensor utilizes a polyaniline-coated PMNA having a density of ∼10,000 microneedles per cm2, containing individual microneedles with a height of ∼250 μm, and a tip diameter of ∼2 μm. To prevent interference from other body fluids like sweat, an insulating layer is deposited at the base of the PMNA. The wearable pH sensor operates from pH 4.0 to 8.6 with a sensitivity of 62.9 mV per pH unit and an accuracy of ±0.036 pH units. Furthermore, testing on a mouse demonstrates the ability of the PMNA to provide a real-time reading of the transdermal pH values. This microneedle-based system will significantly contribute to advancing transdermal wearable sensors technology, simplifying the fabrication process, and improving the cost-effectiveness of such devices.

Abstract
Background Saliva composition has diurnal variations. Citric acid stimulation plays a major role in the change of salivary flow rate and salivary composition. However, diurnal variations and sex differences in salivary alpha-amylase (sAA), pH, salivary flow rate (SFR), and salivary cortisol before and after citric acid stimulation remain unclear. Methods We recruited 30 healthy volunteers, including 15 women (24.7 ± 1.0 years old) and 15 men (25.3 ± 1.3 years old). At four time points (T1, 7:00; T2, 10:00; T3, 16:00; and T4, 20:00), saliva was collected from healthy volunteers before and after citric acid stimulation; and sAA, pH, SFR and salivary cortisol were measured and compared between men and women. Results There were circadian fluctuations in sAA activity, SFR, pH, and cortisol level both before and after citric acid stimulation, and the diurnal fluctuations of these indexes were not affected by citric acid stimulation. There were significant differences in salivary cortisol between men and women before and after acid stimulation in T1. Neither SFR nor pH showed sex-related differences before or after acid stimulation. The variation trend of sAA activity was contrary to that of cortisol, with a significant negative correlation. Conclusions Our data suggest that sAA and cortisol showed diurnal fluctuation, and the variation characteristics of male and female under resting state and acid stimulation were basically the same. The variation trend of salivary alpha-amylase activity was opposite to that of cortisol, with significant negative correlation. Our findings may enable the selection of the correct sampling time for research and the selection of appropriate sampling strategies in studies investigating chronic psychosocial conditions.

Abstract
BACKGROUND College life is characterized by marked increases in alcohol consumption. Extraversion and neuroticism are associated with alcohol use problems in college and throughout adulthood, each with alcohol use patterns consistent with an externalizing and internalizing pathway respectively. Students higher in extraversion drink more frequently and consume more alcohol, while neuroticism is paradoxically not consistently associated with elevated alcohol use. OBJECTIVE This study examined whether students higher in neuroticism may drink the day before stressors, namely tests and assignment deadlines. METHOD Multilevel generalized linear models were performed using data from a longitudinal study of first-time, first-year undergraduates assessing alcohol use across four years of college, with daily diary bursts each semester. RESULTS Students higher in extraversion had heavier alcohol use and greater alcohol use problems in their fourth year of college. Neuroticism was not associated with drinking behaviors or with drinking before a test or assignment, but was associated with greater fourth year alcohol problems. Students lower in extraversion who reduced heavy drinking the day before academic events had fewer alcohol use problems at the fourth year of college relative to students higher in extraversion. CONCLUSIONS Students higher in extraversion appear to exhibit a continuity of established alcohol use patterns from adolescence, predisposing them to a more hazardous trajectory of college alcohol use. Characteristics of low extraversion may afford some protection from alcohol-positive college culture. High neuroticism appears associated with a hazardous trajectory of college alcohol use, but continued research into situational factors of alcohol use in high neuroticism is warranted.

Abstract
Loop-mediated isothermal amplification (LAMP) has been recently studied as an alternative method for cost-effective diagnostics in the context of the current COVID-19 pandemic. Recent reports document that LAMP-based diagnostic methods have a comparable sensitivity and specificity to that of RT-qPCR. We report the use of a portable Arduino-based LAMP-based amplification system assisted by pH microelectrodes for the accurate and reliable diagnosis of SARS-CoV-2 during the first 3 min of the amplification reaction. We show that this simple system enables a straightforward discrimination between samples containing or not containing artificial SARS-CoV-2 genetic material in the range of 10 to 10,000 copies per 50 µL of reaction mix. We also spiked saliva samples with SARS-CoV-2 synthetic material and corroborated that the LAMP reaction can be successfully monitored in real time using microelectrodes in saliva samples as well. These results may have profound implications for the design of real-time and portable quantitative systems for the reliable detection of viral pathogens including SARS-CoV-2.

Abstract
BACKGROUND Medical education has a reputation for being demanding and stressful. However, longitudinal surveys across the whole course of study considering risks and resources are rare. METHODS For the evaluation of stress and coping we administered the standard instruments Perceived Medical School Stress Scale (PMSS), Hospital Anxiety and Depression Scale (HADS), Work-Related Behavior and Experience Patterns (AVEM), Maslach Burnout Inventory (MBI), and a short form of the Coping Orientations to Problems Experienced Scale (Brief COPE) in three consecutive cohorts of medical students (N = 377) at one German university. Students were surveyed at the beginning of their studies (t0) and again during each consecutive summer semester (t1-t6). RESULTS Stress and symptoms of anxiety and depression increased in the first two years of medical studies but decreased again towards their end. Consistently, freshmen medical students presented with a large proportion of the healthy pattern at t0 (56 %) that decreased to 30 % at t2, and increased up to 44 % at t6. Correspondingly, the proportion with the burnout-related risk pattern B increased from 9 to 16 % at t2, again decreasing to 7 % at t6. Over the whole course of study there was an almost continuous increase of the unambitious pattern S from t0 13 to 40 % at t6. Characteristic differences especially between the healthy pattern and the risk patterns regarding stress, mental health symptoms and coping were observed. Female students showed a higher vulnerability for stress, anxiety and depression as well as lower proportions with a healthy pattern, and higher proportions with risk patterns for overexertion and burnout. CONCLUSIONS The development of stress, symptoms and behavior and experience patterns especially in the first two years, demonstrating increasing study-related stress in the preclinical years, as well as the high proportion with an unambitious pattern at the end of the course of study emphasize the need for prevention and health promotion at both the individual and contextual levels.

Abstract
A simple optical pH sensor based on immobilization, Dioscorea alata L. anthocyanin methanol extract, onto a pectin–chitosan polyelectrolyte complex (pectin–chitosan PEC), has been successfully fabricated. The optical pH sensor was manufactured as a membrane made of pectin–chitosan PEC and the extracted anthocyanin. This sensor has the highest sensitivity of anthocyanin content at 0.025 mg/L in phosphate buffer and 0.0375 mg/L in citrate buffer. It also has good reproducibility with a relative standard deviation (%RSD) of 7.7%, and gives a stable response at time values greater than 5 min from exposure in a buffer solution, and the sensor can be utilized within five days from its synthesis. This optical pH sensor has been employed to determine saliva pH of people of different ages and showed no significant difference when compared to a potentiometric method.

Abstract
INTRODUCTION Saliva is increasingly used as a diagnostic tool as it is non-invasive, easily accessible, and less stressful compared to blood sampling. Saliva has a vital role in maintaining oral health. It is necessary for the salivary pH to be neutral in the oral cavity for the optimal functioning of its components. Stress has an effect on salivary pH. OBJECTIVE To study the effect of a mind-body intervention like Sudarshan Kriya yoga (SKY) on the salivary pH. METHODS AND MATERIALS An exploratory pilot study involving an open trial on 321 healthy individuals who were novice to SKY was conducted. The salivary pH was measured before and after a single 90-min session of SKY. RESULTS The salivary pH continued to be neutral after the intervention in the group that had initial neutral pH. There was a statistically significant shift of pH towards neutral in both the groups that had either acidic or alkaline pH initially. CONCLUSION Mind-body interventions like SKY modulate the salivary pH to bring it to the range of optimal functioning. This pilot study provides information for future long-term studies that can be implemented with measures of anxiety and stress along with measuring other salivary biomarkers.

Abstract
Background Recently, the attention of researchers to the study of the properties of human saliva, as a material with unique properties and diagnostic capabilities, has increased. Research objective to study the connection of the biochemical composition of saliva and blood plasma in the norm, depending on gender and age. Methods 107 volunteers took part in the study, including 46 female (37.2 ± 3.9 years old) and 61 male (36.1 ± 2.8 years old). In all samples of saliva and blood plasma, 16 biochemical parameters were determined, including mineral and protein composition, enzyme activity. Non-parametric statistical methods were used to process the data. Results It has been shown that it is difficult to establish an unambiguous relation between biochemical parameters of saliva and blood plasma. The calculation of the Spearman correlation coefficients showed that only 7 of the 16 parameters demonstrate the presence of a weak correlation between the content in saliva and plasma. Conclusion In general, the determination of the composition of saliva may have an independent diagnostic value; in this case, drawing a parallel with the composition of serum and blood plasma is not advisable. Nevertheless, the use of saliva in clinical laboratory diagnostics is associated with the need to establish criteria for the norm and pathology for each biochemical parameter.

Abstract
BACKGROUND Medical education is perceived as demanding and stressful. Whether this is particularly pronounced in this course of study remains under debate. METHODS We used the questionnaire "Work-Related Behavior and Experience Patterns (Arbeitsbezogene Verhaltens- und Erlebensmuster (AVEM))" to assess the development of study-related behavior and experience patterns in medical (n = 584) and STEM students (n = 757) at one German university, with a special emphasis on gender differences, over 3 years of study. Students were surveyed at the beginning of their studies (t0) and again in each consecutive summer semester (t1-t3). Both cross-sectional and longitudinal data were generated and analyzed. Results in the abstract are from the cross-sectional analysis. RESULTS Freshman medical students presented with a larger proportion of students with a healthy pattern (58.1%) than STEM students (42.5%). In both groups this proportion decreased to 33.8%/25.1% at t2, with only a minor improvement at t3 (38.1/27.0%). Correspondingly, the proportion of students with a burnout-related risk pattern increased from 8.0% (Med)/13.7% (STEM) to a maximum of 16.9% at t2 in medical students and 27.0% at t3 in STEM students. In both groups female students showed a more unfavorable distribution of patterns and a higher vulnerability, especially in the area of resistance toward stress. CONCLUSIONS The unfavorable development of behavior and experience patterns in both student groups demonstrates increasing study related stress and emphasizes the need for prevention and health promotion on an individual and a contextual level.

Abstract
Biomimetic cross-reactive sensor arrays (B-CRSAs) have been used to detect and diagnose a wide variety of diseases including metabolic disorders, mental health diseases, and cancer by analyzing both vapor and liquid patient samples. Technological advancements over the past decade have made these systems selective, sensitive, and affordable. To date, devices for non-invasive and accurate disease diagnosis have seen rapid improvement, suggesting a feasible alternative to current standards for medical diagnostics. This review provides an overview of the most recent B-CRSAs for diagnostics (also referred to electronic noses and tongues in the literature) and an outlook for future technological development.

Abstract
Objective: This preliminary study examined if baseline measures of stress-related biomarkers as measured by salivary secretions of specific autonomic [measured by salivary α-amylase (sAA)], endocrine (measured by salivary cortisol), and immune (measured by salivary neopterin) responses are greater in male subjects with tinnitus in response to an induced-stress task. Method: Twenty male subjects with no significant hearing loss, 10 with tinnitus, and 10 without tinnitus were enrolled in this study.Salivary secretions were collected before and after the induced stress task at four different time intervals. Results: sAA levels were lower in the tinnitus group in comparison to subjects without tinnitus, suggesting impaired sympathetic activity in the subjects with tinnitus although these levels remained stable throughout the stress experiment.While no significant effects could be obtained for salivary cortisol or neopterin, salivary neopterin levels were trending toward significance over all measurements. Behavioral measures of stress were found to correlate negatively with measures of sAA and salivary neopterin. Conclusion: The results of this study suggest impaired stress-related sAA mechanisms in male subjects with tinnitus, as evidenced by the different stress reactions induced in the endocrine system (as measured by salivary cortisol) and the immune system (as measured by salivary neopterin).

Abstract
IntroductionSimulation training has been used to teach clinical skills to health profession trainees. Stress and/or anxiety occur in high-acuity scenarios in the clinical environment, and affect clinician performance and patient outcomes. To date, strategies that have been used in conjunction with simulation training for healthcare professionals that address stress management are limited. This paper reports a literature review conducted to explore strategies used with simulations to enhance the ability of health profession trainees in reducing acute stress and/or anxiety during high-acuity clinical events.MethodsDatabases searched included Scopus, PubMed, CINAHL, Web of Knowledge and Science Direct. The examples of the literature chosen were those published in the English language from January 2005 to March 2015, and were peer-reviewed empirical papers that focused on the strategies addressing stress and/or anxiety during simulation training for healthcare profession trainees.ResultsEight studies using various forms of stress/anxiety management strategies with simulations demonstrated varying degrees of effectiveness. Themes that emerged from these eight studies were excessive stress and clinical performance in simulation, emotional training strategies in simulation, and factors contributing to stress and anxiety reduction during simulation.ConclusionsExcessive stress and/or anxiety in the clinical setting have been shown to affect performance and could compromise patient outcomes. Health profession training curricula might benefit from a stress/anxiety reduction strategy integrated into the simulation programmes. This review showed that the stress/anxiety management strategies that have been used with simulations, mostly in surgical training, have various degrees of effectiveness.

Abstract
Inflammation is a part of the complex biological response of inflammatory cells to harmful stimuli, such as pathogens, irritants, or damaged cells. This inflammation has been linked to several chronic diseases including cancer, atherosclerosis, rheumatoid arthritis, and multiple sclerosis. Major biomarkers of inflammation include tumor necrosis factor, interleukins (IL)-1, IL-6, IL-8, chemokines, cyclooxygenase, 5-lipooxygenase, and C-reactive protein, all of which are regulated by the transcription factor nuclear factor-kappaB. Although examining inflammatory biomarkers in blood is a standard practice, its identification in saliva and/or urine is more convenient and non-invasive. In this review, we aim to (1) discuss the detection of these inflammatory biomarkers in urine and saliva; (2) advantages of using salivary and urinary inflammatory biomarkers over blood, while also weighing on the challenges and/or limitations of their use; (3) examine their role(s) in connection with diagnosis, prevention, treatment, and drug development for several chronic diseases with inflammatory consequences, including cancer; and (4) explore the use of innovative salivary and urine based biosensor strategies that may permit the testing of biomarkers quickly, reliably, and cost-effectively, in a decentralized setting.

Abstract
Stress mindset theory suggests that positive stress beliefs lead to positive, rather than negative, outcomes when engaging with stressors. Similarly, the Transactional Model of Stress predicts that perceiving a stressor as challenging leads to positive outcomes whereas negative perceptions of the stressor as threatening invoke negative outcomes. The aim of this study was to provide preliminary data examining the nature of the relationship between stress mindset and primary appraisals. It was predicted that positive beliefs about stress would be associated with perceiving a stressful situation as more challenging, and inversely related to perceptions of threat. Participants (N = 124) initially completed measures assessing stress mindset, lifetime and current perceived stress, trait anxiety, and self-efficacy. Then participants received a set of instructions regarding a stressful mathematics task, followed by completion of post-manipulation stress mindset and primary appraisals measures, prior to completing the mathematics task. Multiple linear regression analyses revealed that participants who held a greater number of positive beliefs (as opposed to negative beliefs) about stress also perceived the stressor as being more challenging. However, there was no significant relationship between valence of beliefs and threat appraisals. These findings provide initial evidence for the nature of the relationship between valence of stress beliefs and challenge appraisals. Further research is needed to understand how stress beliefs impact on the way in which an individual copes with stressful situations.
