This study aimed to assess the correlation between elevated serum cortisol levels and the occurrence of postoperative delirium subsequent to off-pump CABG. Methods: Conducted in the Department of Cardiac Surgery at BSMMU from October 2020 to September 2022, this comparative cross-sectional study included a total of 44 participants. Subjects, meeting specific criteria, were purposefully assigned to two groups based on off-pump CABG. Group A (n = 22) consisted of patients with normal serum cortisol levels, while Group B (n = 22) comprised individuals with high serum cortisol levels on the first postoperative day. Delirium onset was assessed at the bedside in the ICU on the 1st, 2nd, 3rd, 4th, and 5th postoperative days using standard tools, namely the Richmond Agitation Sedation score (RASS) and The Confusion Assessment Method (CAM-ICU). Data were collected based on the presence or absence of delirium. Statistical analysis utilized SPSS version 26.0, employing an independent Student’s t-test for continuous data and chi-square and Fischer’s exact test for categorical data. A p-value ≤ 0.05 was considered statistically significant. Results: Group-A had a mean age of 54.50 ± 17.97, and Group-B had a mean age of 55.22 ± 15.45, both with a male predominance (81.81% and 86.36% respectively). The mean serum cortisol level was significantly higher in Group B (829.71 ± vs. 389.98 ± 68.77). Postoperative delirium occurred in 27.3% of Group B patients, statistically significant compared to the 4.5% in Group A. However, patients in Group B who developed delirium experienced significantly longer postoperative ICU and hospital stays (79.29 ± 12.27 vs. 11.44 ± 2.85, p ≤ 0.05). There was one mortality in Group B, which was statistically not significant. Conclusion: This study observed a significant association between elevated serum cortisol levels in the postoperative period and the occurrence of postoperative delirium after off-pump coronary artery bypass grafting.展开更多

Method: 300 pregnant and postpartum women who were admitted from January 2021 to December 2021 were selected as the research subjects. They were all tested with the Hamilton Anxiety Scale (HAMA) and the Edinburgh Postnatal Depression Scale (EPDS). 40 pregnant women with anxiety and depression were selected as the observation group, and 50 normal pregnant women were selected as the control group, adopting logistic regression analysis to investigate the correlation between salivary cortisol and postpartum anxiety and depression during pregnancy. Result: The salivary cortisol levels in the observation group were significantly higher than those in the control group before bedtime, after waking up the next day, 15 minutes after waking up, 30 minutes after waking up, 60 minutes after waking up, and 1 hour before lunch (p < 0.05). Maternal depression and anxiety were not related to age, weight, gestational age, negative events, or history of adverse pregnancy and childbirth (p > 0.05). Maternal depression and anxiety are closely related to salivary cortisol levels and educational background (p Conclusion: There is a close correlation between anxiety and depression and an increase in cortisol levels, suggesting that the salivary cortisol awakening response during pregnancy has a predictive effect on the occurrence of postpartum depression.展开更多

Cortisol is a hormone that is overexpressed in inflammation and cellular stress processes. Its main function is to return to physiological homeostasis, so its evaluation together with other clinical parameters can allow us to determine the degree of systemic affectation by COVID-19. Objective: To evaluate changes in clinical parameters and plasma cortisol concentrations in patients with active COVID-19 and post-COVID syndrome. Material and Methods: Healthy patients, in stages of mild infection, critical and with post-COVID syndrome, were recruited, obtaining, through clinical diagnoses and interviews, their main clinical characteristics, in addition to plasma, in which cortisol concentrations were determined using competitive ELISA. Results: The critical stage group had higher frequencies of comorbidities, clinical symptoms, as well as more altered laboratory parameters compared to the other subgroups. In the post-COVID syndrome group after the initial infection, most laboratory parameters recovered, however, several clinical symptoms remained latent over time. The determination of cortisol showed an increase in its concentration, being higher in patients in critical stage and with post-COVID syndrome. Conclusion: COVID-19 disease generates clinical alterations that trigger an increase in plasma cortisol. These alterations increase as the stages of infection become more severe and some of them remain altered in patients with post-COVID syndrome.展开更多

We aimed to evaluate prognostic efficacy of cortisol and TFTs in critically ill poisoned patients admitted to toxicology intensive care unit(ICU).METHODS: In a prospective study of consecutively enrolled subjects admitted to the toxicology ICU, lab analyses included TFTs(total T3 and T4 as well as TSH) and cortisol levels drawn between 8 am–10 am during period of the first 24 hours post-ingestion/exposure. Simplified Acute Physiology Score Ⅱ(SAPS Ⅱ) and Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ) were recorded. All scores were compared to detect the best prognostic factor. Type of poisoning was also included.RESULTS: In 200 patients evaluated, 129 were male and mean age was 31 years. In general, SAPS Ⅱ, T4, and cortisol could prognosticate death. After regression analysis, only cortisol had such efficacy(P=0.04; OR=1.06; 95%CI=1.05–1.08; cut-off=42 μg/d L; sensitivity=70%; specificity=82%). Between aluminium phosphide(ALP)-and non ALP-poisoned patients, level of consciousness, mean arterial pressure, and cortisol level could prognosticate death in ALP poisoning(all Ps<0.001 in both uni and multivariate analyses). Median(interquartile range; IQR) GCS was 7(6, 10) and 15(8, 15) in non-ALP and ALP-poisoned patients(P<0.003). SAPS Ⅱ and APACHE Ⅱ could not prognosticate death at all.CONCLUSION: Cortisol best prognosticated outcomes for subjects admitted to the toxicology ICU. Its level is higher in ALP-poisoned patients probably due to the higher stress while they remain conscious till the final stages of toxicity and are aware of deterioration of their clinical condition or may be due to their significantly lower blood pressures.展开更多

By using these fluids instead of blood,the biosensor becomes noninvasive and is less stressful to the end user, who may be a small child or a farm animal.Electroreduced graphene oxide(e-RGO) was used as a synergistic platform for signal amplification and template for bioconjugation for the sensing mechanism on a screenprinted electrode. The cortisol and lactate antibodies were bioconjugated to the e-RGO using covalent carbodiimide chemistry. Label-free electrochemical chronoamperometric detection was used to analyze the response to the desired biomolecules over the wide detection range. A detection limit of 0.1 ng mL^(-1) for cortisol and 0.1 mM for lactate was established and a correlation between concentration and current was observed. A portable, handheld potentiostat assembled with Bluetooth communication and battery operation enables the developed system for point-of-care applications. A sandwich-like structure containing the sensing mechanisms as a prototype was designed to secure the biosensor to skin and use capillary action to draw sweat or other fluids toward the sensing mechanism. Overall, the immunosensor shows remarkable specificity, sensitivity as well as the noninvasive and point-of-care capabilities and allows the biosensor to be used as a versatile sensing platform in both developed and developing countries.展开更多

METHODS: Twenty patients(12 males) with acute relapse of UC started oral PD at a dose of 40 mg once a day, tapered of 10 mg every 2 wk. When a stable 2-wk daily dose of 30 mg was reached, blood samples for cortisol levels' measurement were drawn in the morning in fasting conditions to determine circulating cortisol by LC-MS/MS and ECLIA assay. RESULTS: Median interquartile range cortisolemia with ECLIA and LC-MS/MS method was 54.1(185.8) nmol/L and 32.1(124.0) nmol/L, respectively(P < 0.001). The within-patient median differences between the two methods was 23.2(40.6) nmol/L, with higher cortisol levels for the ECLIA method. The estimated geomet-ric mean ratio between methods was 1.85(95%CI: 2.39-1.43) considering all data or 1.58(95%CI: 2.30-1.09) considering only data above the limit of quantification(n = 12). The 95%CIs of the geometric mean ratio between methods confirm a statistically significant difference.CONCLUSION: Blood cortisol levels detected with ECLIA method seems to be higher than the ones measured by LC-MS/MS, indicating a possible overestimation of them in patients treated with PD. Therefore, the cortisol suppression in patients under treatment with oral PD should not be measured using ECLIA method.展开更多

We analysed the blood test results of nine overweight adults with sedentary lifestyles, and an average BMI of 32.23. Results revealed a statistically significant reduction of visceral adipose tissue, very-low density lipoprotein (VLDL), and triglycerides. Testosterone, leptin, IGF-1 and Free T3 increased within the normal range, juxtaposed by cortisol and ghrelin that declined, but without dipping into abnormality. These findings have important implications during the COVID-19 pandemic, where optimal immunity is deemed necessary in limiting susceptibility to the virus. Recent research indicates that weight gain often escalates vulnerability to respiratory track disturbances, cardiovascular disease (CVD) and diabetes. Consequently, pre-existing conditions increase COVID-19 mortality rates. CVD and diabetes emerge out of hormonal imbalances that involve Free T3, leptin, ghrelin, testosterone, and cortisol. Physical training is decidedly the most acclaimed solution, yet, the least implemented one, due to procrastination, or demoralization after investing constant exhaustive effort with no immediately visible physical change. COVID-19 confinement exacerbates the tendency for inactivity, and promotes stress-eating behaviours. Moreover, strenuous exercise, necessary for visceral fat reduction, results in a negative cortisol/testosterone relationship that provokes caloric consumption and inflammation. Offering an alternative to exercise that effectively improves health, boosts metabolism, and controls appetite, may serve as a proactive, and preventive method that can safeguard health.展开更多

文摘BACKGROUND:The aim of the study was to investigate the procalcitonin-to-cortisol ratio(P/C ratio)as a prognostic predictor among septic patients with abdominal source.METHODS:We retrospectively enrolled 132 post-surgery patients between 18 and 90 years old with sepsis of the abdominal source.On the second day of sepsis onset,cortisol,procalcitonin(PCT),Acute Physiology and Chronic Health Evaluation(APACHE)II score,Sequential Organ Failure Assessment(SOFA)score,C-response protein(CRP),and other baseline characteristics were collected.In addition,the length of ICU stay,length of mechanical ventilation(MV)days,length of shock days,and 28-day mortality were also recorded.Univariate analysis was performed to screen potential risk factors.Stratified analysis was used to identify the interaction among the risk factors.Multivariate analysis was also utilized to demonstrate the relationship between the risk factors and mortality.The receiver operator characteristic(ROC)curve analysis was conducted to evaluate the risk factors.A restricted cubic spline(RCS)demonstrated the association between survival outcome and the P/C ratio variation.RESULTS:A total of twenty-nine patients died,and 103 patients survived within 28 d.There were significant differences in cortisol,PCT,P/C ratio,interleukin(IL)-6,SOFA,and APACHE II scores between the survival and non-survival groups.No significant interaction was observed in the stratified analysis.Logistic regression analysis revealed that P/C ratio(P=0.033)was significantly related to 28-day mortality.Based on ROC curves,P/C ratio(AUC=0.919)had a higher AUC value than cortisol or PCT.RCS analysis depicted a positive relationship between survival possibility and P/C ratio decrement.CONCLUSION:P/C ratio might be a potential prognostic predictor in septic patients with abdominal sources.
文摘BACKGROUND: Prognostic value of cortisol and thyroid function tests(TFTs) has previously been evaluated in medical ICUs. We aimed to evaluate prognostic efficacy of cortisol and TFTs in critically ill poisoned patients admitted to toxicology intensive care unit(ICU).METHODS: In a prospective study of consecutively enrolled subjects admitted to the toxicology ICU, lab analyses included TFTs(total T3 and T4 as well as TSH) and cortisol levels drawn between 8 am–10 am during period of the first 24 hours post-ingestion/exposure. Simplified Acute Physiology Score Ⅱ(SAPS Ⅱ) and Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ) were recorded. All scores were compared to detect the best prognostic factor. Type of poisoning was also included.RESULTS: In 200 patients evaluated, 129 were male and mean age was 31 years. In general, SAPS Ⅱ, T4, and cortisol could prognosticate death. After regression analysis, only cortisol had such efficacy(P=0.04; OR=1.06; 95%CI=1.05–1.08; cut-off=42 μg/d L; sensitivity=70%; specificity=82%). Between aluminium phosphide(ALP)-and non ALP-poisoned patients, level of consciousness, mean arterial pressure, and cortisol level could prognosticate death in ALP poisoning(all Ps<0.001 in both uni and multivariate analyses). Median(interquartile range; IQR) GCS was 7(6, 10) and 15(8, 15) in non-ALP and ALP-poisoned patients(P<0.003). SAPS Ⅱ and APACHE Ⅱ could not prognosticate death at all.CONCLUSION: Cortisol best prognosticated outcomes for subjects admitted to the toxicology ICU. Its level is higher in ALP-poisoned patients probably due to the higher stress while they remain conscious till the final stages of toxicity and are aware of deterioration of their clinical condition or may be due to their significantly lower blood pressures.

文摘DEAR EDITOR,Major depressive disorder (MDD), commonly known as depression, is a mental disease characterized by a core symptom of low mood. It lasts at least two weeks (Badamasi et al., 2019;Wang et al., 2019) and is frequently accompanied by low self-esteem, loss of interest in routinely enjoyable activities, low energy, and unexplained pain (Huey et al., 2018;Park et al., 2012;Post & Warden, 2018;Rice et al., 2019;Xiao et al., 2018). Approximately 2%–8% of adults with MDD commit suicide (Richards & O'Hara, 2014;Strakowski & Nelson, 2015), and around half of suicidal individuals suffer depression or other mood disorders (Bachmann, 2018).
文摘Objective:To investigate the levels of serum Cortisol in patients with uncomplicated Plasmodium falciparum(P.falciparum) malaria in an area of unstable malaria transmission in eastern Sudan. Methods:The concentrations of Cortisol were measured in sera of 25 patients with uncomplicated P.fylciparum malaria(at presentation,24 h and 7 d later) and 25 healthy volunteers using radioimmunoassay gamma counter.Results:There was no significant difference in mean(SD) of total Cortisol levels in patients with malaria in comparison with the control group;602.2(369.6) vs. 449.2(311.7) ng/mL,P=0.12.In patients with uncomplicated P.falciparum malaria,the mean(SD) presenting Cortisol levels were significantly higher in comparison to the levels on day 7;602.2 (369.6) vs.373.6(139.1) ng/mL,P=0.009.In the patients with uncomplicated P.falciparum malaria (on presentation) Cortisol levels were not correlated with initial temperature or the presenting parasitaemia.Conclusions:Thus,Cortisol levels were not significantly different between the patients and the controls.
文摘AIM: To evaluate cortisolemia by using conventional electrochemiluminescence immunoassay(ECLIA) method compared to liquid chromatography-tandem mass spectrometry(LC-MS/MS) method in active ulcerative colitis(UC) patients treated with oral prednisone(PD). METHODS: Twenty patients(12 males) with acute relapse of UC started oral PD at a dose of 40 mg once a day, tapered of 10 mg every 2 wk. When a stable 2-wk daily dose of 30 mg was reached, blood samples for cortisol levels' measurement were drawn in the morning in fasting conditions to determine circulating cortisol by LC-MS/MS and ECLIA assay. RESULTS: Median interquartile range cortisolemia with ECLIA and LC-MS/MS method was 54.1(185.8) nmol/L and 32.1(124.0) nmol/L, respectively(P < 0.001). The within-patient median differences between the two methods was 23.2(40.6) nmol/L, with higher cortisol levels for the ECLIA method. The estimated geomet-ric mean ratio between methods was 1.85(95%CI: 2.39-1.43) considering all data or 1.58(95%CI: 2.30-1.09) considering only data above the limit of quantification(n = 12). The 95%CIs of the geometric mean ratio between methods confirm a statistically significant difference.CONCLUSION: Blood cortisol levels detected with ECLIA method seems to be higher than the ones measured by LC-MS/MS, indicating a possible overestimation of them in patients treated with PD. Therefore, the cortisol suppression in patients under treatment with oral PD should not be measured using ECLIA method.
文摘The purpose of this clinical trial was to delineate some of the negative consequences of high BMI on health and explore the possibility of a solution. We analysed the blood test results of nine overweight adults with sedentary lifestyles, and an average BMI of 32.23. Results revealed a statistically significant reduction of visceral adipose tissue, very-low density lipoprotein (VLDL), and triglycerides. Testosterone, leptin, IGF-1 and Free T3 increased within the normal range, juxtaposed by cortisol and ghrelin that declined, but without dipping into abnormality. These findings have important implications during the COVID-19 pandemic, where optimal immunity is deemed necessary in limiting susceptibility to the virus. Recent research indicates that weight gain often escalates vulnerability to respiratory track disturbances, cardiovascular disease (CVD) and diabetes. Consequently, pre-existing conditions increase COVID-19 mortality rates. CVD and diabetes emerge out of hormonal imbalances that involve Free T3, leptin, ghrelin, testosterone, and cortisol. Physical training is decidedly the most acclaimed solution, yet, the least implemented one, due to procrastination, or demoralization after investing constant exhaustive effort with no immediately visible physical change. COVID-19 confinement exacerbates the tendency for inactivity, and promotes stress-eating behaviours. Moreover, strenuous exercise, necessary for visceral fat reduction, results in a negative cortisol/testosterone relationship that provokes caloric consumption and inflammation. Offering an alternative to exercise that effectively improves health, boosts metabolism, and controls appetite, may serve as a proactive, and preventive method that can safeguard health.
