The acute effect of inhaled nitric oxide on the exercise capacity of patients with advanced interstitial lung disease: a randomized controlled trial

BackgroundInhaled nitric oxide (iNO) selectively acts on the pulmonary vasculature of ventilated lung tissue by reducing pulmonary vascular resistance and intrapulmonary shunt. This effect may reduce ventilation/perfusion mismatch and decrease pulmonary hypertension in patients with interstitial lung disease.MethodsIn a prospective, single-blinded, randomized, placebo-controlled trial, participants with advanced interstitial lung disease, underwent two separate six-minute walk tests (6MWT): one with iNO and the other with a placebo. The primary outcome measured the difference in meters between the distances covered in the two tests. Secondary outcomes included oxygen saturation levels, distance-saturation product, and Borg dyspnea score. A predefined subgroup analysis was conducted for patients with pulmonary hypertension.ResultsOverall, 44 patients were included in the final analysis. The 6MWT distance was similar for iNO treatment and placebo, median 362 m (IQR 265-409) vs 371 m (IQR 250-407), respectively (p = 0.29). Subgroup analysis for patients with pulmonary hypertension showed no difference in 6MWT distance with iNO and placebo, median 339 (256-402) vs 332 (238-403) for the iNO and placebo tests respectively (P=0.50). No correlation was observed between mean pulmonary artery pressure values and the change in 6MWT distance with iNO versus placebo (spearman correlation Coefficient 0.24, P=0.33).ConclusionIn patients with advanced interstitial lung disease, both with and without concurrent pulmonary hypertension, the administration of inhaled nitric oxide failed to elicit beneficial effects on the six-minute walk distance and oxygen saturation. The use of inhaled NO was found to be safe and did not lead to any serious side effects.Trial registration(NCT03873298, MOH_2018-04-24_002331).

MEMS Fingertip Strain Plethysmography for Cuffless Estimation of Blood Pressure.

To develop a cuffless method for estimating blood pressure (BP) from fingertip strain plethysmography (SPG) recordings. A custom-built micro-electromechanical systems (MEMS) strain sensor is employed to record heartbeat-induced vibrations at the fingertip. An XGboost regressor is then trained to relate SPG recordings to beat-to-beat systolic BP (SBP), diastolic BP (DBP), mean arterial pressure (MAP) values. For this purpose, each SPG segment in this setup is represented by a feature vector consisting of cardiac time interval, amplitude features, statistical properties, and demographic information of the subjects. In addition, a novel concept, coined geometric features, are introduced and incorporated into the feature space to further encode the dynamics in SPG recordings. The performance of the regressor is assessed on 32 healthy subjects through 5-fold cross-validation (5-CV) and leave-subject-out cross validation (LSOCV). Mean absolute errors (MAEs) of 3.88 mmHg and 5.45 mmHg were achieved for DBP and SBP estimations, respectively, in the 5-CV setting. LSOCV yielded MAEs of 8.16 mmHg for DBP and 16.81 mmHg for SBP. Through feature importance analysis, 3 geometric and 26 integral-related features introduced in this work were identified as primary contributors to BP estimation. The method exhibited robustness against variations in blood pressure level (normal to critical) and body mass index (underweight to obese), with MAE ranges of [1.28, 4.28] mmHg and [2.64, 7.52] mmHg, respectively. The findings suggest high potential for SPG-based BP estimation at the fingertip. This study presents a fundamental step towards the augmentation of optical sensors that are susceptible to dark skin tones.

Guidelines-based therapeutic strategies for controlling hypertension in non-controlled hypertensive patients followed by family physicians in primary health care in Portugal: the GPHT-PT study

Purpose In a prospective open study, with intervention, conducted in Primary Health Care Units by General Practitioners (GPs) in Portugal, the effectiveness of a single pill of candesartan/amlodipine (ARB/amlodipine), as the only anti-hypertension (anti-HTN) medication, in adult patients with uncontrolled HTN (BP > 140/or > 90 mm Hg), either previously being treated with anti-HTN monotherapies (Group I), or combinations with hydrochlorothiazide (HCTZ) (Group II), or not receiving medication at all (Group III), was evaluated across 12-weeks after implementation of the new therapeutic measure. Materials and methods A total of 118 GPs recruited patients with uncontrolled HTN who met inclusion/exclusion criteria. Participants were assigned, according to severity, one of 3 (morning) fixed combination candesartan/amlodipine dosage (8/5 or 16/5 or 16/10 mg/day) and longitudinally evaluated in 3 visits (v0, v6 and v12 weeks). Office blood pressure was measured in each visit, and control of HTN was defined per guidelines (BP< 140/90 mmHg). Results Of the 1234 patients approached, 752 (age 61 ± 10 years, 52% women) participated in the study and were assigned to groups according to previous treatment conditions. The 3 groups exhibited a statistically significant increased control of blood pressure after receiving the fixed combination candesartan/amlodipine dosage. The overall proportion of controlled HTN participants increased from 0,8% at v0 to 82% at v12. The mean arterial blood pressure values decreased from SBP= 159.0 (± 13.0) and DBP= 91.1 (± 9.6) at baseline to SBP= 132,1 (± 11.3) and DBP= 77,5 (± 8.8) at 12 weeks (p < 0.01). Results remained consistent when controlling for age and sex. Conclusion In patients with uncontrolled HTN, therapeutic measures in accordance with guidelines, with a fixed combination candesartan/amlodipine, allowed to overall achieve HTN control at 12 weeks in 82% of previously uncontrolled HTN patients, reinforcing the advantages of these strategies in primary clinical practice.

Analyzing the application of dezocine combined with psychological care in the postoperative pain management of patients with hemifacial spasm

Objective To analyze the application of Dezocine combined with psychological care in the postoperative pain management. Methods This is a retrospective study. A total of 186 HFS patients who underwent Microvascular Decompression (MVD) at First People’s Hospital of Zunyi between January 2020 and January 2022 were selected as the study subjects. Patients were divided into two groups based on different treatment interventions. The control group (n = 93) received routine perioperative care without preemptive analgesia, while the observation group (n = 93) received preemptive analgesia and combined psychological care on the basis of the control group’s intervention. Results At 30 min post-laryngeal mask removal (T3), no significant difference in Ramsay Sedation Scale scores existed between control and observation groups (p > 0.05). The observation group showed significantly lower RSS scores at immediate mask removal (T2) and VAS scores at T3 compared to controls (p < 0.05). Following intervention, the observation group had notably lower SAS and SDS scores than controls (p < 0.05). Baseline (T0) and 5 min pre-removal (T1) exhibited no significant differences in mean arterial pressure (MAP) and heart rate (HR) values between groups (p > 0.05). However, at T2 and T3, the observation group displayed significantly lower MAP and HR values than controls (p < 0.05). No significant differences in pulse oxygen saturation (SpO2) values existed between groups at any time point (p > 0.05). Conclusion Compared to standard perioperative care alone, Dezocine combined with preemptive analgesia and psychological care effectively reduces postoperative pain during the awakening period, lowers the risk of immediate extubation-related agitation, and maintains stable hemodynamics in the postoperative period.

Comparison of the Effects of Inhalational Anesthesia with Sevoflurane and Total Intravenous Anesthesia in Open Heart Surgery

Background: The primary objective of this study was to compare sevoflurane inhalation anesthesia with total intravenous anesthesia (TIVA) in terms of its effectiveness in maintaining adequate depth of anesthesia during all open heart surgery procedures, including cardiopulmonary bypass. The study's secondary objective was to compare sevoflurane inhalation anesthesia with TIVA regarding the impact on the time of tracheal extubation and the incidence of postoperative acute kidney injury during open heart surgeries. Methods: A total of 58 patients undergoing open heart surgery were included, with 30 receiving sevoflurane inhalation anesthesia and 28 receiving TIVA. Demographic characteristics, intraoperative parameters, and postoperative outcomes were recorded and analyzed. Statistical analysis revealed no significant differences in Bispectral Index (BIS) monitor values, mean arterial pressure, body temperature, or other intraoperative parameters between the two groups. Notably, the time to tracheal extubation was significantly shorter in the Sevoflurane group compared to the TIVA group, although both groups exhibited similar rates of postoperative acute kidney injury (AKI). Results: None of the patients had complaints of intraoperative awareness. The mean arterial pressure, body temperature, and bispectral index values during and before cardiopulmonary bypass were similar between the groups. Postoperative variables such as intensive care unit stay duration, incidence of acute kidney injury, and immediate and 24-hour post-extubation visual analog scale values were similar between the groups. The tracheal extubation time was found to be statistically shorter in the sevoflurane group. Conclusion: We believe that sevoflurane inhalation anesthesia can achieve adequate depth of anesthesia during the intraoperative period in open heart surgery without increasing the rate of postoperative complications.

Triglicerydes/high-density lipoprotein ratio as a risk factor of post-Covid-19 sinus tachycardia: A retrospective study.

Inappropriate sinus tachycardia (IST) is one of the manifestations of the post-COVID-19 syndrome (PCS), which pathogenesis remains largely unknown. This study aimed to identify potential risk factors for IST in individuals with PCS. The 1349 patients with PCS were included into the study. Clinical examination, 24H Holter ECG, 24H ambulatory blood pressure monitoring and biochemical tests were performed 12-16 weeks after the COVID-19 in all participants. IST was found in 69 (3.5%) individuals. In the clinical assessment IST patients were characterized by a higher age (p < 0.001) and lower prevalence of the diagnosed hypertension (p = 0.012), compared to remaining patients. Biochemical testing showed higher serum triglycerides (1.66 vs. 1.31 pmol/L, p = 0.007) and higher prevalence of a low high-density lipoprotein (HDL) cholesterol (24.6% vs. 15.2%, p = 0.035) in the IST group. Subsequently, the triglicerydes (TG)/HDL ratio, an indicator of insulin resistance, was significantly higher in the IST individuals (3.2 vs. 2.4, p = 0.005). 24H monitoring revealed a significantly higher minimum diastolic, maximum systolic and mean arterial blood pressure values in the IST group (p < 0.001 for all), suggesting a high prevalence of undiagnosed hypertension. A multivariate analysis confirmed the predictive value TG/HDL ratio >3 (OR 2.67, p < 0.001) as predictors of IST development. A receiver operating characteristic curve analysis of the relationship between the TG/HDL ratio and the IST risk showed that the predictive cut-off point for this parameter was 2.46 (area under the ROC curve = 0.600, p = 0.004). Based on these findings, one can conclude that insulin resistance seems to be a risk factor of IST, a common component of PCS.

A Direct Assessment of Noninvasive Continuous Blood Pressure Monitoring in the Emergency Department and Intensive Care Unit

IntroductionNoninvasive continuous blood pressure monitoring has the potential to improve patient treatment in the hospital setting. Such noninvasive devices can be applied earlier in the treatment process to empower nurses and clinicians to react more quickly to patient deterioration with the added benefit of eliminating the risks associated with invasive monitoring. However, emerging technologies must be capable of reproducing current clinical measures for medical decision making. MethodsThis study aimed to determine the usability and willingness of nurses to implement a noninvasive continuous blood pressure monitoring device. The secondary aim directly compared the systolic blood pressure, diastolic blood pressure, and mean arterial pressure values recorded by the device (VitalStream; CareTaker Medical LLC, Charlottesville, VA) with the “gold standard” brachial cuff and arterial line measures recorded in the emergency department and intensive care unit settings. ResultsVitalStream was similarly received by nurses in the emergency department and intensive care setting, but ultimately had greater promotion from emergency nurses. Despite some statistical similarity between measurement methodologies, all direct comparisons were found to not meet the Association for the Advancement of Medical Instrumentation 2008 and Association for the Advancement of Medical Instrumentation / European Society of Hypertension / International Organization for Standardization 2019 consensus statement criteria for acceptable blood pressure measure differences between the VitalStream and “gold standard” clinical measures. In all instances, the standard deviation of the Bland-Altman bias exceeded 8 mm Hg with less than 85% of paired differences falling within 10 mm Hg of the “gold standard.” DiscussionTaken together, the tested device requires additional postprocessing for medical decision making in trauma or emergent care.

Effect of Dexmedetomidine on Oxygen and Intrapulmonary Shunt (Qs/Qt) During One-Lung Ventilation in Pediatric Surgery: A Randomized Controlled Trial.

Background One-lung ventilation (OLV) is a common ventilation technique used during thoracic surgery. It can cause serious complications in children, and hypoxic pulmonary vasoconstriction (HPV) is a protective mechanism against the resulting hypoxia.Dexmedetomidine does not affect HPV, so we will investigate its impact on the partial pressure of oxygen in arterial blood (PaO2) and pulmonary shunt fraction (Qs/Qt). Methods Children who underwent OLV were divided into two equal groups. The Dex group received 0.4 μg/kg/h of dexmedetomidine intravenously. The placebo group received normal saline. Two blood samples were taken to analyze arterial and central venous blood gasses during four time periods: T1, 10 minutes after anesthesia; T2, 10 minutes after OLV; T3, 60 minutes after OLV; and T4, 20 minutes after the end of OLV. Heart rate, mean arterial pressure (MAP), PaO2, Qs/Qt, and peak inspiratory pressure (PIP) values were recordedat these time points. Results Regarding heart rate, the Dex group remained relatively stable, whereas the placebo group showed a slight increase in T3 and T4. Concerning MAP, theDex group had a reduction at T1 compared with the placebo group and remained similar for other points. PaO2 decreased with OLV. However, the Dex group consistently maintained higher PaO2 values than the placebo, especially in T3 and T4. Concerning Qs/Qt, the Dex group maintained lower time values than the placebo group at OLV. Regarding PIP, the Dex group had significantly lower T2 and T3 than the placebo group. Conclusion Administration ofdexmedetomidine inchildren with OLV improves PaO2 and reduces pulmonary shunt fraction (Qs/Qt), thereby improving oxygen transport. It reduces the maximum PIP values, thereby reducing pressure-related complications.

Risk factors contributing to infection with SARS-CoV-2 are modulated by sex.

Throughout the early stages of the COVID-19 pandemic in Mexico (August-December 2020), we closely followed a cohort of n = 100 healthcare workers. These workers were initially seronegative for Immunoglobulin G (IgG) antibodies against SARS-CoV-2, the virus that causes COVID-19, and maintained close contact with patients afflicted by the disease. We explored the database of demographic, physiological and laboratory parameters of the cohort recorded at baseline to identify potential risk factors for infection with SARS-CoV-2 at a follow-up evaluation six months later. Given that susceptibility to infection may be a systemic rather than a local property, we hypothesized that a multivariate statistical analysis, such as MANOVA, may be an appropriate statistical approach. Our results indicate that susceptibility to infection with SARS-CoV-2 is modulated by sex. For men, different physiological states appear to exist that predispose to or protect against infection, whereas for women, we did not find evidence for divergent physiological states. Intriguingly, male participants who remained uninfected throughout the six-month observation period, had values for mean arterial pressure and waist-to-hip ratio that exceeded the normative reference range. We hypothesize that certain risk factors that worsen the outcome of COVID-19 disease, such as being overweight or having high blood pressure, may instead offer some protection against infection with SARS-CoV-2.

Evaluation of Analgesic Nociceptive Index in intraoperative and postoperative pain management in general anesthesia applied with two different methods

Aim: Effectiveness of analgesic nociceptive index (ANI) monitoring in predicting both intraoperative and postoperative early pain in neurosurgery patients undergoing lumbar spinal surgery. The patients were administered general anesthesia using different anesthesia management techniques.Method: The study included a total of 60 patients with American Society of Anesthesiologist (ASA) I-III. The patients were randomly divided into two groups of 30 each using the closed envelope method. Group T received total intravenous anesthesia (TIVA) with remifentanil-propofol, while Group D with desflurane-remifentanil. Non-invasive ANI monitoring was applied to patients undergoing lumbar spinal surgery, and ANI, heart rate, systolic/diastolic arterial pressure values were recorded before and after induction, skin incision, major muscle incision, laminectomy, right-left fasciectomy, screw fixation, after extubation and during the postoperative period. Post-operative heart rate, ANI value, mean arterial pressure values, and visual analog scale (VAS) values were measured.Results: No statistically significant difference was found in terms of the demographic data of the patients. According to the groups, no statistically significant difference was found between the ANI and VAS measurements of the cases at the postoperative 5th minute (P=0.261), postop 10th minute (P=0.379), postop 15th minute (P=0.673), postop 30th minute (P=0.784) and postop 60 minute (p =0.750).Conclusions: In our study on lumbar spine surgery, we could not detect any significant relationship between ANI monitoring and VAS values in the early postoperative period. There was no difference in ANI and VAS with either anaesthetic technique. In light of the results of our study, we believe that more studies are needed on the use of ANI monitoring in the early postoperative period.

ВЛИЯНИЕ ПЕРЕНЕСЕННОЙ НОВОЙ КОРОНАВИРУСНОЙ ИНФЕКЦИИ НА СТРУКТУРНО-ФУНКЦИОНАЛЬНЫЕ ПАРАМЕТРЫ ПРАВЫХ ОТДЕЛОВ СЕРДЦА И ЛЕГОЧНУЮ ГЕМОДИНАМИКУ У БОЛЬНЫХ ХРОНИЧЕСКОЙ ОБСТРУКТИВНОЙ БОЛЕЗНЬЮ ЛЕГКИХ

Abstract. Introduction. This paper presents the interim results of a prospective clinical study, in which we studied the long-term influence of 2019 novel coronavirus infection (2019-nCoV) on pulmonary-cardiac relationships in patients with chronic obstructive pulmonary disease. Aim: Studying the effect provided by the previous 2019-nCoV on the structural and functional parameters of the right ventricle of the heart and on pulmonary hemodynamics in patients with chronic obstructive pulmonary disease. Materials and Methods. Over the years 2021-2023, we examined 43 patients with stable chronic obstructive pulmonary disease, having a history of 2019-nCoV by transthoracic echocardiography. The study consisted of two control points: on day 8-12 in the hospital and the follow-up visit to the clinic 12 months after 2019-nCoV. The study included a control group of 30 stable chronic obstructive pulmonary disease patients having no 2019-nCoV history. Results and Discussion. We found that the structural and functional strains of the right heart are aggravated in the acute period of 2019-nCoV in patients with chronic obstructive pulmonary disease. Thus, as compared to the control group, the maximum right atrium width (p&lt;0.05), right ventricle anterior wall thickness (p&lt;0.05), and basal right ventricle diameter values were significantly higher. Echocardiographic signs of right ventricle diastolic dysfunction Type 1 were found in 36,3% of cases and Type 2 in 23.3%. Pulmonary artery diameter and mean pulmonary artery pressure were higher than in those of the control group, as well. In 44% of patients, the value of pulmonary artery acceleration time was less than 105 ms (χ2 = 4.59; p&lt;0.05). Persistently high linear and volumetric right atrium and right ventricle indicators were registered in patients after 12 months of follow-up. Signs of the Type 1 diastolic dysfunction were found in 62.7% of patients. There was a tendency to decrease the mean pulmonary artery pressure and pulmonary artery acceleration time values. Conclusions. Thus, according to echocardiography, the combination of chronic obstructive pulmonary disease and 2019-nCoV leads to the aggravation of right ventricle diastolic dysfunction and the progression of pulmonary hypertension. These signs persisted for a long time (12 months).

Effects of Pulsatile and Non-Pulsatile Cardiopulmonary Bypass Techniques in Coronary Artery Bypass Grafting Surgeries on Cerebral Perfusion.

We aimed to evaluate the effects of cardiopulmonary bypass (CPB) machines used in coronary artery bypass grafting surgeries on cerebral perfusion by performing cerebral oximetry monitoring [near-infrared spectroscopy (NIRS)], S100-β protein measurements, and neurocognitive function assessment tests using both pulsatile and non-pulsatile modes. A total of 44 patients, 22 non-pulsatile (Group NP) and 22 pulsatile (Group P), were included in the study. Hemodynamic parameters, arterial blood gas values, NIRS values and blood S100β protein levels were analyzed at five points: pre-induction (T1), initiation of CPB (T2), termination of CPB (T3), end of surgery (T4), and postoperative 24 h (T5). Two different neuropsychological tests were administered to patients in the preoperative and postoperative periods. There were no significant differences between the groups for demographic characteristics such as age, gender, body mass index, aortic cross-clamping, CPB, and operation durations. The mean arterial blood pressure and PaO2 values for the T2 measurements were significantly higher in group NP (P < 0.05). Regional cerebral oxygen saturation (rSO2) (NIRS) values at T3 and T4 were significantly higher in group P (P < 0.05). Serum S100β measurement values at T3 and T5 were significantly higher in group NP than in group P (P < 0.05). Serum S100β protein levels at T3 correlate with rSO2 results. There was no statistically significant difference between the two groups in terms of pH, lactate, glucose, partial pressure of carbon dioxide, and peripheral oxygen saturation values. Despite no difference between the two groups for neurocognitive function tests, we believe that pulsatile perfusion may be more beneficial for cerebral perfusion when S100β protein and NIRS values are considered. Further clinical studies are needed to evaluate the benefits of the pulsatile technique for cerebral perfusion.

Association between low values of mean arterial pressure and impaired cognitive performance in older patients with mild cognitive impairment: cross-sectional preliminary findings from the STRENGTH Project

BackgroundUncontrolled blood pressure (BP) is a risk factor for Mild Cognitive Impairment (MCI) and dementia.AimsThis study examined the relationship between BP and clinical/cognitive/neuropsychological aspects in MCI individuals.MethodsMCI patients underwent clinical, functional, cognitive and metacognitive, as well as psychological assessments. Social network, lifestyle characteristics, and medication prescriptions were also evaluated. Each patient underwent BP measurements.ResultsLower values of systolic BP (SBP), diastolic BP (DBP), and mean arterial pressure (MAP) were associated with poorer cognitive performance. Notably, MAP showed greater capability in detecting impairments in attention and visuospatial abilities compared to SBP and DBP.DiscussionThese findings support the notion that in older individuals with MCI excessively low BP values, particularly MAP, might represent a risk and suggest that cerebral hypoperfusion may play a key role.ConclusionsRoutine assessment of MAP could aid clinicians in adjusting antihypertensive treatment and closely monitoring cognitive function in MCI patients.

Analgesic and hemodynamic effects of intravenous magnesium sulfate infusion versus lidocaine infusion in patients undergoing thyroid surgery for toxic goiter resection: a randomized controlled study

Background Anesthesia for toxic goiter resection is challenging as manipulation of the thyroid gland and inadequate postoperative pain control could lead to hemodynamic instability due to stress and a neurohormonal response. Both magnesium sulfate and lidocaine are known for their analgesic effects and decreasing stress response. Herein, we compared the previous two medications regarding intraoperative hemodynamics and postoperative analgesia. Patients and methods 57 patients who underwent toxic goiter resection were enrolled in this prospective randomized trial (group M received magnesium sulfate, group L received lidocaine, and group C received normal saline). Intraoperative hemodynamics and postoperative analgesic profiles were assessed. Results Both injection groups expressed significantly lower pain scores compared with control group at Post anaesthesia care unit (PACU) and one-hour postoperative. Postoperative fentanyl consumption was significantly lower, and the time to first analgesic request was significantly prolonged in Magnesium and Lidocaine groups than in the control group. The previous beneficial effects were more prominent in the Magnesium Group compared with the Lidocaine Group. There was no significant difference in mean arterial pressure (MAP) and heart rate (HR) among the three study groups at the baseline, after the end of infusion, and after induction. Nonetheless, there was a significant rise in mean arterial pressure and heart rate values in the control group compared with the Magnesium and Lidocaine Groups with intubation and during the first hour of surgery. Conclusion Both magnesium sulfate and lidocaine have beneficial hemodynamic stabilizing and analgesic effects in patients undergoing thyroid surgery for toxic goiter, with a slight superiority for magnesium.

Spiritual Meaning Impacts Psychological Distress and Control of Mean Arterial Pressure in Hypertension Patients

Hypertension is a disease that can cause various complications and is made worse by psychological distress, where cases are increasing at the Bangkalan Community Health Center. This research aims to analyze the correlation between spiritual meaning in regulating psychological distress and mean arterial pressure (MAP) in hypertension patients. This research method is correlation analytic with a cross-sectional approach with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guideline. population of 76 patients and a sample of 62 taken using simple random sampling. The independent variable is spiritual meaning, measured using the Daily Spiritual Experience Scale (DSES). Meanwhile, the dependent variable is distress, measured by the Kessler Psychological Distress Scale and the mean arterial pressure (MAP) value. The collected data was then subjected to statistical tests using Spearman ranks with an alpha value of 0.05. The research results show a relationship between spiritual meaning and psychological distress with a p-value of 0.016 &lt; 0.05 and a correlation coefficient of -0.305. Spirituality is also significantly related to the mean arterial pressure (MAP) value with p value 0.005 &lt; 0.05, and the correlation coefficient is -0.351. Spirituality has an impact on reducing psychological distress, affecting the function of the Hypothalamus Pituitary Adrenal (HPA) Axis and Sympathetic Adrenal Medullary (SAM) Axis. The SAM Axis will balance the secretion of norepinephrine (NE) and epinephrine (E), which affects the balance of contraction of smooth cardiac muscle cells, vasoconstriction and vasodilation, heart rate, and normalizes sodium levels so that it can control blood pressure in hypertensive patients.

Triiodothyronine hormone supplementation therapy in septic shock patients with euthyroid sick syndrome: two pilot, placebo-controlled, randomized trials

BackgroundTo assess 28-day survival in two pilot groups of septic shock patients with euthyroid sick syndrome (ESS) supplemented with triiodothyronine (T3). MethodsA total of 95 septic shock patients with ESS were divided according to values of the thyroid hormones into low T3 and low T3T4 groups. Among 48 patients with low T3, 24 (50%) were randomized to T3 for 4 days and 24 (50%) to placebo. Among 47 patients with low T3T4, 24 (51%) were randomized to T3 for 4 days and 23 (49%) to placebo. The analysis included 28-day survival as the primary outcome and laboratory with hemodynamics as the secondary outcomes. Laboratory data were analyzed on the day of admission (T0), on the first (T1), third (T2) and seventh day (T3) with hemodynamics analyzed for the first four days. ResultsIn the low T3 population, 18 (75%) patients receiving T3 died at day 28 compared with 8 (33.3%) patients receiving placebo (p = 0.004). In the low T3T4 population, 6 (25%) patients receiving T3 died in ICU compared with 12 (52.1%) patients receiving placebo (p = 0.039). Oral T3 treatment increased mean arterial pressure values at day 1, day 3 and day 7 in the low T3T4 population, (p = 0.015, =0.005 and =0.042 respectively), and had no significant effect on these values in the low T3 population. ConclusionT3 supplementation was associated with a low 28-day mortality rate in patients with low T3T4 but with increased mortality in patients with low T3 ESS. These results suggest caution before initiating thyroid supplementation in septic patients. RegistrationClinTrials.gov (NCT05270798).

Factors Associated with Hypertension Among Adults: A Cross-Sectional Analysis of the Indonesian Family Life Survey.

Hypertension (HTN) poses a significant health risk for Indonesia's large population. Underlying factors contributing to this disease are not fully understood at a national level. Therefore, this study aimed to evaluate factors associated with HTN in Indonesia. This study used data from the Indonesian Family Life Survey-5, a 2014 national cross-sectional population-based survey of individuals aged 15 years and older. The mean arterial pressure (MAP) value was determined from three blood pressure measurements taken by trained nurses using Omron digital sphygmomanometers. The respondent was classified as hypertensive when the MAP value was at least 100. The study summarised the socio-demographic factors (age, gender, marital status, ethnicity and occupation status) and lifestyle habits (smoking, sleep quality, physical activity) with descriptive statistics. The potential associations between these factors and HTN were assessed using logistic regression analysis. The results were reported in terms of odds ratios (OR) with a 95% confidence interval (CI). The study included 32,670 respondents; 31.2% of them had HTN. Factors that were more likely associated with HTN were being <65 years old, being married (OR 1.257, 95% CI 1.170-1.352) and being smoker (OR 1.297, 95% CI 1.198-1.404), while being male (OR 0.677, 95% CI: 0.625-0.733) and doing no physical activity (OR 0.870, 95% CI: 0.813-0.930) were less likely to be associated with HTN. This study indicates that there are associations between certain socio-demographic factors and lifestyle habits with HTN in Indonesia. This information may help policymakers and healthcare providers to develop effective strategies in order to control HTN in Indonesia, thereby improving the overall health and well-being of the population.

Intraoperative hypotension affects postoperative acute kidney injury depending on the invasiveness of abdominal surgery: A retrospective cohort study.

Intraoperative hypotension (IOH) or highly invasive surgery adversely affects postoperative clinical outcomes. It is, however, unclear whether IOH affects postoperative acute kidney injury (AKI) depending on the invasiveness of abdominal surgery. We speculated that IOH in highly invasive abdominal surgery is a significant risk factor for postoperative AKI. We retrospectively reviewed the data of 448 patients who underwent abdominal surgery. Patients were divided into 3 groups: highly (such as pancreaticoduodenectomy and hepatectomy), moderately (open abdominal surgery), and minimally (laparoscopic surgery) invasive surgeries. The association between the time-weighted average (TWA) of mean arterial pressure (MAP) values (≤60 and ≤ 55 mm Hg) and AKI occurrences in each group was assessed. Postoperative AKI occurred after highly, moderately, and minimally invasive surgeries in 33 of 222 (14.9%), 14 of 110 (12.7%), and 12 of 116 (10.3%) cases, respectively (P = .526). The median [interquartile range] of TWA-MAP ≤ 60 mm Hg, as an IOH parameter, was 0.94 [0.33-2.08] mm Hg in highly, 0.54 [0.16-1.46] mm Hg in moderately, and 0.14 [0.03-0.57] mm Hg in minimally invasive surgeries (P < 0001). In addition, there was a significant association between TWA-MAP and AKI in highly invasive surgery, unlike in moderately and minimally invasive surgery, with adjusted odds ratios (95% confidence interval) for TWA-MAP ≤ 60 and ≤ 55 mm Hg associated with AKI of 1.23 [1.00-1.52] (P = .049) and 1.55 [1.02-2.36] (P = .041), respectively. Intraoperative MAP ≤ 60 mm Hg in highly invasive abdominal surgery is associated with postoperative AKI, compared to moderately and minimally invasive surgeries. Additionally, low MAP thresholds in highly invasive surgery increase postoperative AKI risk.

Postoperative Analgesic Effect of Bilateral Quadratus Lumborum Block (QLB) for Canine Laparoscopic Ovariectomy: Comparison of Two Concentrations of Ropivacaine

The aim of this study was to evaluate the effect of the transverse quadratus lumborum block (QLBLQL-T) on time to the first postoperative rescue analgesia in dogs submitted to laparoscopic ovariectomy. A total of twenty-three female dogs were included. Dogs were randomly assigned to receive a bilateral QLBLQL-T, performed either with 0.3 mL kg−1 ropivacaine 0.5% [group QLB0.5% (n = 8)] or with ropivacaine 0.33% [group QLB0.33% (n = 8)] or a fentanyl-based protocol [group No-QLB (n = 7)]. Dogs were premedicated intravenously (IV) with fentanyl 5 mcg kg−1, general anesthesia was induced IV with propofol and maintained with sevoflurane. Invasive mean arterial pressure (MAP) values were recorded five minutes before and five minutes after performing the QLBLQL-T. The short-form of the Glasgow composite measure pain scale was used every hour after extubation, and methadone 0.2 mg kg−1 was administered IV when pain score was ≥5/24. Kolmogorov–Smirnov test, ANOVA test combined with Tukey post hoc test, Student’s T-test and Chi-square test were used to analyze data; p &lt; 0.05. Time from QLBLQL-T to the first rescue analgesia was significantly longer in QLB0.5% than in group QLB0.33% and No-QLB. MAP pre- and post-block decreased significantly only in group QLB0.33%.

Comparative investigation of pulmonary vasodilating effects of inhaled Nitric Oxide (NO) gas therapy and inhalation of SIN-1, a new drug formulation containing an NO-donor metabolite

Abstract Background The management of acute pulmonary hypertension has recently been in the center of attention as Coronavirus Disease 2019 (COVID-19) might lead to acute respiratory distress syndrome associated with hypoxia-induced pulmonary vasoconstriction. Therefore inhalation therapy has been the object of several clinical trials. Purpose In this experimental study we aimed at investigating the hemodynamic effect of inhalative SIN-1a (3-morpholino-syndnonimine, the unstable active metabolite of molsidomine, stabilized by cyclodextrine) administration during physiological and pathological conditions in a large animal model. Methods Landrace pigs were randomized into the following experimental groups: iNO (inhaled nitric-oxide, n=3), SIN-1-5 (5 mg, n=3), SIN-1-10 (10 mg, n=3). Hemodynamic parameters were recorded after parallel insertion of PiCCO system and Swan-Ganz catheter. The effect of iNO and SIN-1 inhalation (30 min) was investigated under physiologic conditions and U46619, a thromboxane-receptor agonist induced pulmonary hypertension. Results The observed alterations after inhalation therapy were quite similar under physiological and pathological condition. Pulmonary arterial pressure (PAP) was decreased by all of these drugs, SIN-1-10 had similar effect as iNO (physiological contidiont: -36.1% iNO, -23.8% SIN-1-5, -35.5% SIN-1-10; U46619-induced pulmonary hypertension: -30.1% iNO, -22.1% SIN-1-5, -31.2% SIN-1-10). While iNO therapy did not influence the mean arterial pressure (MAP) and systemic vascular resistance (SVR) values, SIN-1 administration resulted in decreased MAP and SVR values. Pulmonary vascular resistance (PVR) was decreased by iNO greater than with using SIN-1. As a result of these alterations, the PVR/SVR ratio decreased markedly in the iNO group, while it was stepwisely increased in the SIN-1-5 and SIN-1-10 group. Conclusion The pulmonary vasodilator effect of SIN-1 was dose dependent, and in case of larger dose it was comparable to that of iNO. However, the vasodilatory effects of SIN-1 inhalation was not limited to the pulmonary circulation, a significant and dose-dependent systemic vasodilation could also be documented.
