Comparative Study Of Standard Drug Dose Mixture Versus Fentanyl In Attenuating Stress Response During Laryngoscopy And Tracheal Intubation In Neurosurgery: A Prospective Observational Study

Background: Opioid-free anesthesia (OFA) is gaining prominence, particularly in neurosurgery, due to its potential to minimize opioid-related complications such as postoperative nausea and vomiting (PONV) and shivering. This Prospective observational study aims to compare the efficacy of a standard drug dose mixture comprising intravenous magnesium sulphate, lignocaine, paracetamol, and tramadol with fentanyl in attenuating the hemodynamic stress response during laryngoscopy and tracheal intubation. Methods: Sixty neurosurgical patients, aged 18 to 60 years, undergoing cervical or lumbar discectomies under general anesthesia in our institute were divided into two groups. One group received the standard drug dose mixture, and the other received fentanyl. Hemodynamic parameters, including pulse rate, blood pressure, oxygen saturation (SpO2), and electrocardiogram (ECG) changes, were recorded at baseline, during intubation, and at one- minute intervals for five minutes post-intubation. Results: Both groups demonstrated stable hemodynamics with no significant differences in pulse rate or blood pressure. No ECG abnormalities were observed, and SpO2 remained above 96% in all patients. Additionally, the standard drug dose mixture group showed a reduced incidence of PONV and shivering compared to the fentanyl group. Conclusion: The standard drug dose mixture provides a safe and effective alternative to fentanyl for attenuating the hemodynamic stress response during laryngoscopy and tracheal intubation, with fewer side effects. Further randomized controlled trials are recommended to confirm these findings and explore the benefits of opioid-free anesthesia in various surgical procedures.

Comparison of the Effect of Scalp Block With Ropivacaine vs. Ropivacaine and Clonidine on Postoperative Pain in Patients Undergoing Craniotomy Surgery Under General Anesthesia.

Introduction Clonidine, an α2 agonist known for its hypotensive and analgesic effects, has proven beneficial in various routes of administration such as oral, intravenous, and local infiltration. Scalp blocks enhance hemodynamic stability during surgery and reduce intraoperative opioid requirements compared to controls in numerous studies. Additionally, they are effective in managing postoperative pain, resulting in reduced opioid consumption. Research has shown that clonidine can enhance and prolong the effects of intrathecal, epidural, and peripheral nerve blocks (e.g., brachial plexus, peribulbar). Here, we investigated the impact of adding clonidine at a dose of 1 μg/kg to scalp blocks performed with 0.5% ropivacaine for supra-tentorial craniotomy Material and methods This study was conducted on 60 patients under theAmerican Society of Anesthesiologists (ASA) grade I and II who were scheduled for elective supratentorial craniotomy. Patients were divided into two equal groups of 30 and received a scalp block following general anesthesia. Patients in Group A (n=30) received a scalp block of 0.5% ropivacaine plus 1 ml of normal saline (total 21 cc). Patients in Group B (n=30) received a scalp block of 0.5% ropivacaine and clonidine (1 μg/kg) combined with 0.5 ml of normal saline (total 21 cc). Blood pressure, heart rate, peripheral oxygen saturation (SpO2), visual analog score, Ramsay sedation score, duration of analgesia, and analgesia requirement in the first 24 hours were recorded from baseline and postoperatively. Results The duration of first rescue analgesia for Group A was 4.30 ± 1.5 hours and that of Group B was 9.10 ± 1.4 hours. Duration of analgesia was significantly prolonged in patients receiving ropivacaine with clonidine for scalp nerve block. The amount of tramadol given in the first 24 hours in Group A, 62.50 ± 25.00 mg, was highcompared to Group B, 57.14 ± 18.89 mg. The mean arterial blood pressure differed significantly in both groups at 30 minutes, 1 hour, 3 hours, and 12 hours after scalp block postoperatively and lower in Group B. Although changes in pulse rate, and SpO2 were not statistically significant in both groups, patients were hemodynamically stable and did not require any ionotropic support. Ramsay sedation score and visual analog score postoperatively were not significant. There were no significant adverse effects noted in any groups. Conclusion Our study concluded that administering clonidine at a dosage of 1 μg/kg, in combination with 0.5% ropivacaine for scalp nerve block procedures, significantly extends the duration of analgesia and enhances its quality, all while maintaining stable hemodynamic parameters.

Comparison of General Anesthesia and Spinal Anesthesia on Hemodynamic Stability in Patients Undergoing Hernia Repair

Introduction. The issue of choosing the optimal anesthesia that is least dangerous to the patient’s life is still the main concern of the workers in the anesthesia and intensive care department, including techniques, medications, plans, and instructions followed in order to choose the best anesthesia. It can also be said that spinal anesthesia is the best and most standard anesthesia for those who repair hernia.The aim of the study — learn about obtaining and verifying hemodynamic stability in patients undergoing hernia repair under anesthesia.Materials and methods. An accurate and recent study of patients attending Al-Hussein Medical City and Al-Hassan Hospital in the city of Karbala. We included 100 patients who underwent a herniotomy, were divided into two groups on the types of general and spinal anesthesia. Fifty patients received general anesthesia and 50 patients received spinal anesthesia. Data related to the patient’s age, weight, change in blood pressure and pulse rate were analyzed. The study analyzed patients aged 20–90, dividing them into two groups: general anesthesia (GA) and spinal anesthesia (SA), for careful follow-up before, during, and after operations.Results. We show that it is also more stable in SA which is about 56 % in comparison to GA which is about 40 % but increased blood pressure is more in GA which was 32 % and 24 % in SA, but decreased blood pressure is also more in GA which was 28 % and in SA was 20 %. In this study, as shown, there is more stability in heart rate, which is 56 % in SA but in GA it is 32 % and the increase in heart rate was 34 % in SA but was 60 % in GA. The decreased heart rate was 10 % in SA and about 8 % in GA and the effect of SA is more stable.Conclusions. We found spinal anesthesia was more than general anesthesia in stability of blood pressure and heart rate and minimum or normal.

Feasibility, acceptability, and preliminary efficacy of smartphone-based virtual reality relaxation in chemotherapy patients: A pilot study

Background & Aim: While virtual reality holds promise for enhancing patient management and experience during chemotherapy, its use remains limited. The present study aimed to test the feasibility, acceptability, and preliminary efficacy of smartphone-based virtual reality relaxation (SVR) in chemotherapy patients. Methods & Materials: In this pilot study, 29 participants were divided into two groups. The SVR group (n=14) experienced a 10-minute virtual reality intervention, while the control group (n=15) received standard care and guided imagery leaflets. Outcomes such as comfort, anxiety, pain, systolic blood pressure (SBP), diastolic blood pressure (DBP), and pulse rate were evaluated at baseline and post-chemotherapy. The Technology Acceptance Model (TAM) questionnaire and open-ended questions evaluated SVR’s acceptability. Data was analyzed using descriptive statistics, non-parametric t-tests, and thematic analysis. Results: The SVR intervention appears feasible, as evidenced by a high recruitment rate of 93.75% (30 out of 32 eligible patients) and a retention rate of 96.67% (29 out of 30 participants), despite one withdrawal. The SVR group showed significant comfort improvement (P=0.002), significant changes in pulse rate (P=0.047), and SBP (P=0.023) compared to the control group. Anxiety, pain, pulse rate, and DBP showed no significant differences. A significant TAM variable (P<0.001) confirmed the intervention's acceptability. Qualitative feedback showed no serious side effects and patients reported positive experiences. Conclusion: The SVR intervention, feasible and acceptable, significantly improved comfort and altered pulse rate and SBP in chemotherapy patients. It shows potential as an oncology care strategy. Further validation is needed through large-scale trials.

The Impact of Videofluoroscopic Pulse Rate on Duration and Kinematic Measures in Infants and Adults with Feeding and Swallowing Disorders.

This investigation assessed the impact of temporal resolution during a videofluoroscopic evaluation of swallowing (VFSS) on measures of duration and kinematics. Thirty adult and ten infant swallow studies, all acquired at 30 frames and 30 pulses per second, were obtained from a New Mexico hospital. All swallow studies were altered to simulate 15 and 5 pulses per second. Duration measures included pharyngeal response time, duration of upper esophageal sphincter (UES) opening, velopharyngeal closure duration and total swallow duration. Kinematic measures were assessed in adults only and included peak hyoid position and extent of UES opening during the swallow. Analysis of outcome measures was performed and compared across the three temporal resolutions (30, 15, and 5 pulses per second). For data points where normative values are available, we evaluated the impact of temporal resolution on clinical determination (i.e., did a change in pulse rate alter the clinical classification). Kinematic and duration measures were altered with changes in pulse rate and these changes increased as temporal resolution decreased. For outcome measures where normative values are available, accuracy of clinical determination decreased with decreased pulse rate. Temporal resolution impacts duration and kinematic measures. However, the direction of these changes is unpredictable, indicating sensitivity and specificity are both affected. Without a predictable impact, the use of lower pulse rates may alter clinical impressions and treatment recommendations yielding inappropriate treatment goals and treatment duration.

Clemastine as a Main Sedative Drug in Colonoscopy

Background: Colonoscopy is the endoscopic examination of the large bowel and the distal part of the small bowel with a CCD camera or a fiber-optic camera on a flexible tube passed through the anus. It can provide a visual diagnosis. Methods: In this study, clemastine plus fentanyl was compared with fentanyl plus midazolam in analgesia during colonoscopy. Patients were monitored for pain and hemodynamic changes. The mean age in the group treated with clemastine was 52 years and in the group treated with midazolam was 54 years. There were 56 males and 35 females in the study. There was no significant difference in gender in the two groups. Systolic blood pressure was 109.9 mmHg before and 109.35 mmHg after clemastine administration, which showed no significant difference. Results: Diastolic blood pressure was 72.2 mmHg before and 73.7 mmHg after clemastine administration, which showed no significant difference. No change in mean pulse rate (PR) was seen (84/min before and after clemastine administration). In the group receiving midazolam, systolic and diastolic blood pressure changes were not significant, but changes in PR and arterial oxygen saturation were significantly different. Meanwhile, the two groups had a significant lower pain level after colonoscopy in the group receiving clemastine compared to midazolam. Conclusion: Based on the results of the present study, clemastine can be used as a main drug for sedation during colonoscopy.

Benefit of breath-holding training on the concept of recreational freediving in healthy adults – a systematic literature review

Additionally, studies have shown significant improvements in cardiorespiratory function in individuals with bronchial asthma, chronic obstructive pulmonary disease, and cancer. These improvements were evidenced by positive changes in pulse rate, blood pressure, respiratory function measurements, and overall quality of life.

Nocturnal vestibular stimulation using a rocking bed improves a severe sleep disorder in a patient with mitochondrial disease.

Mitochondrial diseases are rare genetic disorders often accompanied by severe sleep disorders. We present the case of a 12-year-old boy diagnosed with a severe primary mitochondrial disease, exhibiting ataxia, spasticity, progressive external ophthalmoplegia, cardiomyopathy and severely disrupted sleep, but no cognitive impairment. Interestingly, his parents reported improved sleep during night train rides. Based on this observation, we installed a rocking bed in the patient's bedroom and performed different interventions, including immersive multimodal vestibular, kinesthetic and auditory stimuli, reminiscent of the sensory experiences encountered during train rides. Over a 5-month period, we conducted four 2-week nocturnal interventions, separated by 1-week washout phases, to determine the subjectively best-perceived stimulation parameters, followed by a final 4-week intervention using the optimal parameters. We assessed sleep duration and quality using the Mini Sleep Questionnaire, monitored pulse rate changes and used videography to document nocturnal interactions between the patient and caregivers. Patient-reported outcome measures, clinical examinations and personal outcomes of specific interests were used to document daytime sleepiness, restlessness, anxiety, fatigue, cognitive performance and physical posture. In the final 4-week intervention, sleep duration increased by 25%, required caregiver interactions reduced by 75%, and caregiving time decreased by 40%. Subjective fatigue, assessed by the Checklist Individual Strength, decreased by 40%, falling below the threshold of severe fatigue. Our study suggests that rocking beds could provide a promising treatment regime for selected patients with persistent severe sleep disorders. Further research is required to validate these findings in larger patient populations with sleep disorders and other conditions.

Intranasal dexmedetomidine as premedication for magnetic resonance imaging examinations in dogs with neurological disorders mitigates hypotension and hypothermia.

This study aimed to evaluate the safety and feasibility of intranasal administration of dexmedetomidine as a premedication for preventing hypotension and hypothermia in canine patients undergoing MRI examinations. Dogs undergoing MRI examinations for neurological disorders were enrolled in this study. The dogs were randomly assigned: 15 to the N-Dex group (without premedication) and 13 to the Dex group (125 μg/m2 of dexmedetomidine, intranasally, as a premedication). During the examination, pulse rate, systolic blood pressure, diastolic blood pressure, and mean arterial blood pressure were recorded every 5 minutes for the first 30 minutes. Body temperature was measured before and after the examination. Any adverse events during the procedure were documented. Significant changes in pulse rate during the examination were not distinguishable. Although blood pressure and body temperature decreased in both groups under anesthesia, dogs in the Dex group had a significantly smaller drop in blood pressure and body temperature and fewer hypotension events than those in the N-Dex group MRI examinations of 1 hour's duration. Two dogs in the Dex group exhibited bradycardia at 45 and 60 minutes of MRI examination, which resolved after receiving atipamezole. Our results indicate that intranasal administration of 125 μg/m2 of dexmedetomidine as premedication is safe and can potentially mitigate hypothermia and hypotension in dogs with neurological disorders during MRI examinations.

Effect of the Location of Tetanic Stimulation on Autonomic Responses: A Randomized Cross-Over Pilot Study.

Tetanic stimuli are used as standardized noxious inputs to investigate nociception. Previous studies have applied tetanic stimuli to various anatomical locations without validating that the resulting physiological responses were independent of the location where tetanic stimuli were applied. Our aim was to investigate the effects of three anatomical tetanic stimulus application sites on physiological variables reflecting autonomic nervous system responses as measured by photoplethysmography (PPG). Under general anesthesia, a five second, 100 hertz, 70 milliamp tetanic stimulus was applied to the ulnar nerve, medial side of the tibia, and thorax (T5 dermatome) (N=12). The effect of tetanic stimuli on PPG-derived variables (AC, DC, and ACDC) and pulse rate at each stimulus location was determined using repeated-measures analysis of variance (ANOVA) followed by Dunnett's post hoc test. Maximum tetanic stimulus-induced changes in PPG-derived variables and pulse rates were compared among the three stimulus locations using ANOVA. AC and ACDC values of PPG decreased, and the DC values of PPG increased in response to tetanic stimuli-induced vasoconstriction at each location (p<0.001 for all). The maximum changes in the AC, ACDC, and DC values did not differ between locations (p=NS). There were no significant changes in pulse rate (p=NS). The results showed that tetanic stimulation at either of these three locations provides the same autonomic nervous system responses, as measured by PPG. ClinicalTrials.gov; NCT03648853.

Heart rate and insula activity increase in response to music in individuals with high interoceptive sensitivity.

Interoception plays an important role in emotion processing. However, the neurobiological substrates of the relationship between visceral responses and emotional experiences remain unclear. In the present study, we measured interoceptive sensitivity using the heartbeat discrimination task and investigated the effects of individual differences in interoceptive sensitivity on changes in pulse rate and insula activity in response to subjective emotional intensity. We found a positive correlation between heart rate and valence level when listening to music only in the high interoceptive sensitivity group. The valence level was also positively correlated with music-elicited anterior insula activity. Furthermore, a region of interest analysis of insula subregions revealed significant activity in the left dorsal dysgranular insula for individuals with high interoceptive sensitivity relative to individuals with low interoceptive sensitivity while listening to the high-valence music pieces. Our results suggest that individuals with high interoceptive sensitivity use their physiological responses to assess their emotional level when listening to music. In addition, insula activity may reflect the use of interoceptive signals to estimate emotions.

Abstract 12149: Vericiguat May Improve Conduit Vessel Function and Exercise Functional Capacity in Heart Failure With Reduced Ejection Fraction

Background: The treatment of heart failure with reduced ejection fraction (HFrEF) has advanced considerably in recent years with the advent of novel agents; however, limitations, such as blood pressure and renal dysfunction, limit the number of patients who can benefit from this treatment in practice. Vericiguat, a novel heart failure treatment, has been found to be efficacious in patients with HFrEF while maintaining a good safety profile. Unfortunately, its mechanisms remain largely unknown. Objective and Methods: A total of 11 patients with HFrEF who were determined to be inadequately treated underwent right heart catheterization, echocardiography, flow-mediated dilatation (FMD) testing, 6-min walking distance (6MWD) test, and blood sampling at a median interval of 70 ± 13 days before and after vericiguat treatment. Results: Participating patients were 73 ± 9.3 years old with a mean of 2.5 repeated heart failure hospitalizations, ejection fraction (EF) of 31.2% ± 8.7%, BNP of 328.7 ± 282, and New York Heart Association classification of mostly II. No significant changes in systolic blood pressure or pulse rate were observed before and after vericiguat introduction (115 ± 64 vs. 105 ± 52 mmHg and 70 ± 5 vs. 75 ± 12 bpm; P = 0.533 and 0.960, respectively). No significant changes in the mean pulmonary artery pressure and pulmonary artery wedge pressure were also observed before or after drug administration (19 ± 5 vs. 17 ± 10 mmHg and 7 ± 5 vs. 9 ± 3 bpm; P = 0.177 and 0.240 respectively). However, cardiac output was significantly increased and vascular resistance was significantly decreased after vericiguat treatment (4.0 ± 1.0 vs. 4.3 ± 1.1 L/min and 1719 ± 462 vs. 1467 ± 377 dynes·sec·cm-5; P = 0.016 and 0.002, respectively). FMD test results improved significantly after treatment (4.5 ± 5% vs. 8.1± 8%: P = 0.027), with the 6MWD increasing significantly by 42 m (311 ± 100 vs. 353 ± 50 m; P = 0.035). BNP also decreased significantly, whereas eGFR remained unchanged (317 ± 274 vs. 221.5 ± 200 pg/mL and 51.7 ± 21 vs. 51.5 ± 25.3 mL/min/1.73 m 2 ; P = 0.015 and 0.967, respectively). Conclusion: Vericiguat may improve exercise tolerance by improving vascular endothelial function and cardiac output.

Autonomic dysregulation during sleep in Parkinsonian spectrum disorders - A proof of concept

IntroductionAutonomic dysfunction is common in α-synucleinopathies such as Lewy Body dementias (LBD), Parkinson's disease (PD), and isolated REM Sleep Behavior Disorder (iRBD). We analyzed pulse-rate changes during sleep to index autonomic nervous system (ANS) dysfunction in patients with α-synucleinopathies vs. non-synucleinopathy groups expected to have normal ANS function. MethodsPatients with LBD (n = 16), PD (PD, n = 14) or iRBD (n = 12) were compared to the non-synucleinopathy groups Alzheimers disease dementia (ADem, n = 26), mild cognitive impairment (MCI, n = 34) or controls (CG, n = 54). Sleep Profiler was used to derive a sleep autonomic activation index (AAI), i.e., ≥6 beat-per-minute increase/decrease, pulse rate coefficient of variation (PR-CV), and automated sleep staging with sleep-spindles and non-REM hypertonia (NRH). Analysis included statistical group comparisons and receiver operating characteristics curves to determine optimal classification of groups. ResultsAAI and PR-CV were moderately correlated across all recordings (rs = 0.58, P < 0.0001), except in the LBD and PD groups. AAI but not PR-CV differentiated the LBD, PD and iRBD from non-Parkinsonian groups. AAI was decreased in LBD and PD patients compared to the CG (p < 0.003) and MCI (p < 0.03). AAI decreased based on age and its receiver operating characteristic area under the curve ranged from 0.63 to 0.75. AAI had a weak negative correlation to NRH (rs ≤ −0.26) but not sleep-spindles. ConclusionSynucleinopathy-related ANS dysfunction can reasonably discriminate prodromal and manifest PD/LBD diseased groups from non-synucleinopathies. Further studies incorporating AAI into a multivariate classifier of neurodegenerative disorders based on sleep characteristics acquired in the patient's home are planned.

Joint modeling of longitudinal changes of pulse rate and body temperature with time to recovery of pneumonia patients under treatment: a prospective cohort study

BackgroundPneumonia is the leading infectious cause of mortality worldwide and one of the most common lower respiratory tract infections that is contributing significantly to the burden of antibiotic consumption. The study aims to identify the determinants of the progress of pulse rate, body temperature and time to recovery of pneumonia patients.MethodA prospective cohort study design was used from Felege Hiwot referral hospital on 214 sampled pneumonia patients from March 01, 2022 up to May 31, 2022. The Kaplan–Meier survival estimate and Log-Rank test was used to compare the survival time. Joint model of bivariate longitudinal and time to event model was used to identify factors of longitudinal change of pulse rate and body temperature with time to recovery jointly.ResultAs the follow up time of pneumonia patient’s increase by one hour the average longitudinal change of pulse rate and body temperature were decreased by 0.4236 bpm and 0.0119 {C}^{0}. The average longitudinal change of pulse rate and body temperature of patients who lived in rural was 1.4602 bpm and 0.1550 {C}^{0} times less as compared to urban residence. Patients who had dangerous signs are significantly increased the average longitudinal change of pulse rate and body temperature by 2.042 bpm and 0.6031 {C}^{0} as compared to patients who had no dangerous signs. A patient from rural residence was 1.1336 times more likely to experience the event of recovery as compared to urban residence. The estimated values of the association parameter for pulse rate and body temperature were -0.4236 bpm and -0.0119 respectively, which means pulse rate and body temperature were negatively related with patients recovery time.ConclusionPulse rate and body temperature significantly affect the time to the first recovery of pneumonia patients who are receiving treatment. Age, residence, danger sign, comorbidity, baseline symptom and visiting time were the joint determinant factors for the longitudinal change of pulse rate, body temperature and time to recovery of pneumonia patients. The joint model approach provides precise dynamic predictions, widespread information about the disease transitions, and better knowledge of disease etiology.

Comparative efficacy and safety profile of once-weekly Semaglutide versus once-daily Sitagliptin as an add-on to metformin in patients with type 2 diabetes: a systematic review and meta-analysis

Background The emergence of genetically-modified human proteins and glucagon-like peptide-1 (GLP-1) receptor agonists have presented a promising strategy for effectively managing diabetes. Due to the scarcity of clinical trials focusing on the safety and efficacy of semaglutide as an adjunctive treatment for patients with type 2 diabetes who had inadequate glycemic control with metformin, we conducted a systematic review and meta-analysis. This was necessary to fill the gap and provide a comprehensive assessment of semaglutide compared to sitagliptin, a commonly prescribed DPP-4 inhibitor, in this patient population. Methods A comprehensive and systematic search was carried out on reputable databases including PubMed, the Cochrane Library, and Elsevier’s ScienceDirect to identify relevant studies that compared the efficacy of once-weekly Semaglutide with once-daily Sitagliptin in individuals diagnosed with type 2 diabetes mellitus. The analysis of the gathered data was performed utilizing the random-effects model, which considers both within-study and between-study variations. Results The meta-analysis incorporated three randomized controlled trials (RCTs), encompassing 2401 participants, with a balanced distribution across the treatment groups. The primary focus of the study revolved around evaluating changes in HbA1C, blood pressure, pulse rate, body weight, waist circumference, and BMI. The findings revealed that once-weekly Semaglutide showed substantially improved HbA1C (WMD: −0.98; 95% CI: −1.28, −0.69, p-value: < 0.0001; I2: 100%), systolic (WMD: −3.73; 95% CI: −5.42, −2.04, p-value: <0.0001; I2: 100%) and diastolic blood pressures (WMD: −0.66; 95% CI: −1.02, −0.29, p-value: 0.0005; I2: 100%), and body weight (WMD: −3.17; 95% CI: −3.84, −2.49, p-value: <0.00001; I2: 100%) compared to once-daily Sitagliptin. However, there was an observed increase in pulse rate (WMD: 3.33; 95% CI: 1.61, 5.06, p-value: <0.00001; I2: 100%) associated with Semaglutide treatment. Regarding secondary outcomes, there was an elevated risk of total adverse events and premature treatment discontinuation with Semaglutide. The risk of serious, severe, moderate, and mild adverse events did not significantly differ between the two treatments. Conclusions In conclusion, the administration of once-weekly Semaglutide exhibited a substantial reduction in HbA1c, average systolic blood pressure (SBP), mean diastolic blood pressure (DBP), body weight, waist circumference, body mass index (BMI), and a rise in pulse rate, as opposed to the once-daily administration of Sitagliptin.

Physical Artificial Arterial Pulse System for Development and Testing of PPG-Based Sensors.

A physical system to generate a PPG-mimicking signal was designed and validated using everyday low-cost components to aid in medical sensor design. The pulse waveform was created by driving a working fluid into a silicone tube and changing the pressure within it. The corresponding waveform mimics a PPG signal through an artery, is adaptable, and repeatable. The working fluid is interchangeable allowing for change of blood analyte concentrations for development and testing of PPG-based sensors. The system was validated by black ink water compared to water and air compared to water testing to confirm optical transparency of the tube. The produced PPG signal, pulse rate and pressure change were compared to that seen in subjects.

Thus, the system can mimic arterial pulses, creating a valid PPG signal that can be detected by PPG-based sensors.Clinical Relevance- Provides a low-cost, adaptable, physical PPG signal generator for research and development of optical medical sensor technologies.

PRE-DISCHARGE SYSTOLIC BLOOD PRESSURE IN HOSPITALIZED COVID-19 PATIENTS IS AN INDEPENDENT PREDICTOR OF IMROVEMENT IN 6-MINUTE WALK TEST DURING 1-MONTH FOLLOW-UP

Objective: To study the relation of hypertensive status and systolic blood pressure (SBP) pre-discharge values to the dynamics of functional re-conditioning as assessed by 6-minute walk distance during the 1-month follow-up after hospitalization for COVID-19. Design and method: 6-minute walk distance (6MWD) was assessed pre-discharge in 176 patients hospitalized for COVID-19 (40% hypertensive, 47% male, mean age 53,2 ± 13,5 years) using the 20 m walkway and an extended protocol that included monitoring of peripheral pulse and capillary blood oxygen saturation (SpO2) every 30 seconds via bluetooth-connected pulse oximeter. The repeated evaluation was performed after 1 month of follow-up. Results: Hypertensive participants were characterised by older age (57,8±11,8 vs 50,7±13,9, p &lt; 0,001), higher weight and body mass index (31,7±5,3 vs 27,4±4,4 kg/m2, p &lt; 0,001). As a result, 6MWD in them was shorter (378±57 vs 418±75 m, p = 0,001) but no difference in reached percent of predicted distance (6MWD%) was detected (63,0±8,5 vs 63,2±11,1 %, p = 0,939). The described relation persisted at 1 month, with no difference in absolute (72±43 vs 68±43 m, p = 0,324) and percentage gain of 6MWD (12,8±6,6 vs 11,2±7,5 %, p = 0,266) between groups. Multiple regression analysis has allowed to build the model that accounted for 94% of variability in the 6MWD% gain between visits (85% for dedicated hypertensive cohort model). After adjustment for age, sex, height, weight, Remdesivir treatment, minimal SpO2 levels during acute COVID-19, changes of SpO2 and pulse rate throughout the 6MWT, SBP remained a potent independent predictor of 6MWD% gain, with 10 mmHg higher values at baseline evaluation being associated with 21,5% lesser 6MWD% gain in hypertensive subjects and 8,2% lesser – in normotensives. Conclusions: Hypertensive status did not have an impact on 6MWD% in pre-discharge COVID-19 patients. Moderate-to-high quality multiple regression models have demonstrated an independent role of SBP, demographic and anthropometric data, changes of SpO2 and pulse rate throughout the 6MWT in prediction of 6MWD% gain during 1 month after discharge, both in hypertensive and normotensive patients.

Pulse Wave Measuring Sensor System via the Average Magnitude Difference Function Entropy for Classifying Cardiac Conditions

The formation and changes of the pulse wave are affected by the functional status of the heart, blood, and arterial vessels. The pulse signal covers pathological information in the cardiovascular system, and the doctor of traditional Chinese medicine (TCM) can diagnose diseases by feeling the pulse. The diagnosis of diseases through feeling the pulse of TCM primarily relies on the doctor’s feelings and subjective experience, and it lacks objectified data. In this work, pulse signals were collected digitally by designing pulse sensors and pulse acquisition systems in accordance with the feel pulse habits of TCM. The pulse rate variability was used to characterize the functional state of the heart. The average magnitude difference function (AMDF) fuzzy entropy method was proposed to investigate the change in pulse rate. A total of 77 volunteers with different heart health conditions were recruited for the collection of the pulse signal. Results showed that the AMDF fuzzy entropy can distinguish clearly among knotted pulse, regular intermittent pulse, and normal pulse. Therefore, this method has potential application value to realize cardiac-function state analysis and abnormal recognition.
