Prognostic Value of Admission Lactate Levels in Critically Ill Patients: A Comparative Study With Sequential Organ Failure Assessment and Acute Physiology and Chronic Health Evaluation II Scores

Prognostic Value of Admission Lactate Levels in Critically Ill Patients: A Comparative Study With Sequential Organ Failure Assessment and Acute Physiology and Chronic Health Evaluation II Scores

Predictive value of the CURB-65, qSOFA, and APACHE II for in-hospital mortality in patients with acute exacerbation chronic obstructive pulmonary disease.

This study aimed to evaluate the efficacy of Quick Sequential Organ Failure Assessment, Confusion, Urea, Respiratory Rate, Blood Pressure, and Age Above or Below 65 Years (CURB-65), and Acute Physiology and Chronic Health Evaluation (APACHE) II in predicting the in-hospital mortality of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). This retrospective study was conducted on 1583 hospitalized patients diagnosed with AECOPD from 2017 to 2019. Appropriate clinical data were retrieved from medical records from the time of admission up until the patients were discharged. The patients' most severe physiological condition and laboratory data within the first 24 hours of admission were used to determine CURB-65, Quick Sequential Organ Failure Assessment, and APACHE II scores. The accuracy of these 3 instruments in predicting the in-hospital mortality of patients with AECOPD was compared. It was observed that patients who had died had significantly higher APACHE II and CURB-65 scores (P < .05). Binary logistic regression analysis confirmed their significant association with mortality. The APACHE II score had a sensitivity of 91.6% and a specificity of 89.2%, while CURB-65 had a sensitivity of 94% and a specificity of 67.2%. The receiver operating characteristic curves for APACHE II and CURB-65 showed high predictive accuracy (area under the curve, 0.965 and 0.882, P < .001), respectively. Mortality rates substantially increased with higher scores (P < .001), reaching 38.2% for APACHE II scores ≥16 and 15.8% for CURB-65 scores ≥2. Our findings reveal a clear link between higher mortality rates and higher APACHE II and CURB-65 scores. The receiver operating characteristic curves' strong predictive ability highlights the dependability of these scoring systems in assessing the risk of in-hospital mortality, making them useful tools for predicting the outcomes in critical care.

Elevated Cardiac Troponin Levels as a Predictor of Increased Mortality Risk in Non-Cardiac Critically Ill Patients Admitted to a Medical Intensive Care Unit.

Background: Cardiac troponin I (TnI) is a specific marker of myocardial damage used in the diagnosis of acute coronary syndrome (ACS). TnI levels can also be elevated in patients without ACS, which is linked to a worse prognosis and mortality. We evaluated the clinical implications and prognostic significance of serum TnI levels in critically ill non-cardiac patients admitted to the intensive care unit (ICU) at a tertiary-level hospital. Materials and Methods: A three-year retrospective study including the years 2017-2020 was conducted to evaluate in-hospital mortality during ICU stay and mortality rates at 28 and 90 days, as well as one and two years after admission, in 557 patients admitted to the medical ICU for non-cardiac causes. Results: TnI levels were elevated in 206 (36.9%) patients. Patients with elevated TnI levels were significantly older and had higher rates of comorbidities, including chronic heart failure, coronary heart disease, and chronic kidney disease (p < 0.05 for all). Patients with elevated TnI levels required more invasive mechanical ventilation, vasopressor infusion, and dialysis in the ICU and experienced more shock within the first 72 h (p = 0.001 for all). High TnI levels were associated with higher Acute Physiological and Chronic Health Evaluation (APACHE) II (27.6 vs. 20.3, p = 0.001) and Sequential Organ Failure assessment (8.8 vs. 5.26, p = 0.001) scores. Elevated TnI levels were associated with higher mortality rates at 28 days (58.3% vs. 19.4%), 90 days (69.9% vs. 35.0%), one year (78.6% vs. 46.2%), and two years (82.5% vs. 55.6%) (p < 0.001 for all). Univariate logistic regression analysis revealed that high TnI levels were a strong independent predictor of mortality at all time points: 28 days (OR = 1.2, 95% CI: 1.108-1.3, p < 0.001), 90 days (OR = 1.207, 95% CI: 1.095-1.33, p = 0.001), one year (OR = 1.164, 95% CI: 1.059-1.28, p = 0.002), and two year (OR = 1.119, 95% CI: 1.026-1.22, p = 0.011). Multivariate analysis revealed that age, albumin level, APACHE II score, and requirements for dialysis and vasopressor use in the ICU were important predictors of mortality across all timeframes, but elevated TnI levels were not. Conclusions: Elevated TnI levels in critically ill non-cardiac patients are markers of disease severity. While elevated TnI levels were significant predictors of mortality in the univariate analysis, they lost significance in the multivariate model when adjusted for other factors. Patients with elevated TnI levels had higher mortality rates across all timeframes, from 28 days to two years.

Concordance of Chest Radiography and Chest Computed Tomography Findings in Patients with Hematologic Malignancy and Invasive Mucormycosis: What Are the Prognostic Implications?

Invasive pulmonary mucormycosis (IPM) is a deadly opportunistic mold infection in patients with hematological malignancies (HM). Radiologic imaging is essential for its timely diagnosis. Here, we compared IPM lesions visualized by chest computed tomography (CCT) and chest X-ray (CXR) and determined the prognostic significance of discordant imaging. Therefore, we reviewed 44 consecutive HM patients with probable/proven IPM at MD Anderson Cancer Center in 2000-2020 who had concurrent CCT and CXR studies performed. All 44 patients had abnormal CCTs and 39 (89%) had anormal CXR findings at IPM diagnosis. However, only 26 patients (59%) showed CCT-matching IPM-suspicious lesions on CXR. Acute Physiology and Chronic Health Evaluation II score > 18 at IPM diagnosis and breakthrough infection to Mucorales-active antifungals were the only independent risk factors for 42-day and/or 84-day mortality. Absence of neutropenia at IPM diagnosis, neutrophil recovery in neutropenic patients, and surgical revision of mucormycosis lesions were protective factors. Although not reaching significance on multivariable analysis, visualization of CCT-matching lesions on CXR was associated with significantly increased 84-day mortality (log-rank test, p = 0.033), possibly as a surrogate of extensive lesions and tissue necrosis. This observation supports the exploration of radiologic lesion kinetics as a prognostic staging tool in IPM patients.

Effectiveness of a Digital Health Intervention Leveraging Reinforcement Learning: Results From the Diabetes and Mental Health Adaptive Notification Tracking and Evaluation (DIAMANTE) Randomized Clinical Trial.

Digital and mobile health interventions using personalization via reinforcement learning algorithms have the potential to reach large number of people to support physical activity and help manage diabetes and depression in daily life. The Diabetes and Mental Health Adaptive Notification and Tracking Evaluation (DIAMANTE) study tested whether a digital physical activity intervention using personalized text messaging via reinforcement learning algorithms could increase step counts in a diverse, multilingual sample of people with diabetes and depression symptoms. From January 2020 to June 2022, participants were recruited from 4 San Francisco, California-based public primary care clinics and through web-based platforms to participate in the 24-week randomized controlled trial. Eligibility criteria included English or Spanish language preference and a documented diagnosis of diabetes and elevated depression symptoms. The trial had 3 arms: a Control group receiving a weekly mood monitoring message, a Random messaging group receiving randomly selected feedback and motivational text messages daily, and an Adaptive messaging group receiving text messages selected by a reinforcement learning algorithm daily. Randomization was performed with a 1:1:1 allocation. The primary outcome, changes in daily step counts, was passively collected via a mobile app. The primary analysis assessed changes in daily step count using a linear mixed-effects model. An a priori subanalysis compared the primary step count outcome within recruitment samples. In total, 168 participants were analyzed, including those with 24% (40/168) Spanish language preference and 37.5% (63/168) from clinic-based recruitment. The results of the linear mixed-effects model indicated that participants in the Adaptive arm cumulatively gained an average of 3.6 steps each day (95% CI 2.45-4.78; P<.001) over the 24-week intervention (average of 608 total steps), whereas both the Control and Random arm participants had significantly decreased rates of change. Postintervention estimates suggest that participants in the Adaptive messaging arm showed a significant step count increase of 19% (606/3197; P<.001), in contrast to 1.6% (59/3698) and 3.9% (136/3480) step count increase in the Random and Control arms, respectively. Intervention effectiveness differences were observed between participants recruited from the San Francisco clinics and those recruited via web-based platforms, with the significant step count trend persisting across both samples for participants in the Adaptive group. Our study supports the use of reinforcement learning algorithms for personalizing text messaging interventions to increase physical activity in a diverse sample of people with diabetes and depression. It is the first to test this approach in a large, diverse, and multilingual sample. ClinicalTrials.gov NCT03490253; https://clinicaltrials.gov/study/NCT03490253. RR2-10.1136/bmjopen-2019-034723.

The effect of using low dose norepinephrine before hypotensive resuscitation in hemorrhagic shock; a randomized controlled trial

Background &amp; Objectives: Hemorrhagic shock is not a very rare occurrence in big hospitals. It might be encountered in the emergency room (ER) or in the operating rooms (OR). A rapid response and systematic management will save the life of the victim. The objective of this research was to investigate the impact of a low dose of norepinephrine (NE) administered prior to the initiation of hypotensive resuscitation in patients with hemorrhagic shock. Methodology: This randomized controlled trial was conducted on 200 participants, at least 18 years old, classified as severely traumatized and had significant hemorrhage with mean arterial pressure ranging from 65 to 75 mmHg. We divided the patients into two equal groups. Group I received a low dose of NE (&lt; 0.3 µg/kg/min) concurrently with resuscitation fluids. Group II received resuscitative fluids only. If the resuscitative fluids failed to keep mean arterial pressure (MAP) &gt; 65 mmHg, the patient was progressively administered NE even with high doses (0.05 to more than 0.3 µg/kg/min). The primary outcome was 24-hour mortality. In-hospital mortality, incidence of acute kidney injury (AKI), and duration of hospital and intensive care unit (ICU) stay constituted the secondary outcomes. Results: Group I had lower 24-hour mortality compared to Group II (3% vs 13%; P &lt; 0.05). Compared to Group II, Group I needed reduced amount of fluid resuscitation within 24 h, had lower serum lactate levels at 6 and 12 h, and lower serum creatinine at 6, 12, and 18 h (P &lt; 0.001). Group I had a lower incidence of mechanical ventilation (13% vs 27%), hospital and ICU stays, and in-hospital mortality (9% vs 21%) (P &lt; 0.05). There was a lack of disparity seen in the incidence of AKI and duration of mechanical ventilation. Conclusion: Low-dose norepinephrine infusion during the early period of hypotensive resuscitation reduces resuscitative fluid requirement, improves tissue perfusion, preserves renal function, and lowers mortality in hemorrhagic shock patients.

Antifungal susceptibility, molecular epidemiology, and clinical risk factors of Candida glabrata in intensive care unit in a Chinese Tertiary Hospital.

The increasing incidence and high mortality rate of Candida glabrata infection in ICU patients is an important issue. Therefore, it is imperative to investigate the antifungal susceptibility profiles and epidemiological characteristics in local regions. Herein, antifungal susceptibility testing was conducted to determine the minimum inhibitory concentrations (MICs) of eight antifungal drugs. Multilocus sequence typing (MLST) was used to study the strain genotype, geographical distribution, and susceptibility to antifungal agents among C. glabrata isolates. The mechanism of echinocandin resistance was explored by sequencing the FKS1 and FKS2 genes (encoding 1,3-β-D-glucan synthases) of echinocandin-resistant C. glabrata strains. Moreover, we further investigated the clinical manifestations and the various risk factors of patients infected with C. glabrata in the ICU. We selected 234 C. glabrata isolates from 234 patients in the ICU randomly for the follow-up study. Cross-resistance was found among the ICU C. glabrata isolates. Analysis using MLST showed that the genetic diversity among the C. glabrata isolates was low. Furthermore, sequence type showed no correlation with the antifungal resistance profiles, but was associated with geographical distribution. We also revealed novel mutations in FKS1 (S629P) and FKS2 (W1497stop) that mediated high-level echinocandin resistance (MIC >8 µg/mL). More than 14 days' stay in ICU (P=0.007), Acute Physiology and Chronic Health Evaluation II (APACHE-II) score (P=0.024), prior antifungal exposure (P=0.039) and lung disease (P=0.036) were significantly associated with antifungal resistant/non-wild-type C. glabrata infection. Our study shed light on the antifungal susceptibility, molecular epidemiology, and clinical risk factors of C. glabrata in the ICU of a Chinese Tertiary Hospital. Importantly, we revealed the molecular mechanism of echinocandin resistance. These results highlight the significance of continued surveillance in ICUs and provide data support for the treatment of C. glabrata in clinics.

Validity and Reliability of the Persian Translation of the World Health Organization (WHO) Oral Health Self-assessment Questionnaire for Children and Adolescents

Background: Regularly assessing the oral health of children and adolescents is crucial. Researchers seek valid and reliable questionnaires to obtain comparable global data, enabling oral health evaluation in large populations, remote regions, or even during an epidemic like COVID-19, while saving time and money. Objectives: The present study was conducted to translate and validate the Persian version of the World Health Organization (WHO) Oral Health Self-assessment Questionnaire for Children and Adolescents. Methods: In 2022, a cross-sectional study was conducted in Kerman, Iran. The Persian questionnaire was tested on 20 individuals to assess the fluency and clarity of the Persian translation. The questionnaire was then filled out by 40 individuals, and reliability was evaluated using the test-retest method. The final questionnaire was completed by 878 randomly selected participants aged 7 - 18 years online. To establish concurrent validity, the researchers added three questions related to the presence of toothache without dental visits, filled teeth, and teeth with endodontic treatment. Internal consistency was checked by calculating Cronbach's alpha coefficient. Results: A total of 290 students aged 7 to 12 and 588 students aged 13 to 18 participated in the study. Cronbach’s alpha for the entire questionnaire was 0.656 for students under 12 years old and 0.643 for those over 12 years old. The intra-cluster correlation coefficient for both age groups was between 0.81 and 0.87. Examining the concurrent validity of this questionnaire showed that the three additional questions added by the researchers have a significant relationship with the questions describing the health of teeth and gums (oral health), the number of times participants felt toothache in the last 12 months, and the problem of biting and chewing. However, they had no significant relationship with the risk factor related to nutrition. Moreover, the questionnaire is multifactorial. Conclusions: The Persian version of the WHO Oral Health Self-assessment Questionnaire for Children and Adolescents is reliable over time. If the questionnaire is repeated and the responses of people in the same population are collected, it yields similar results. It has internal consistency, but it is a multi-factor questionnaire.

Evaluation of Health Associations With Height-Normalised Abdominal Body Composition Indices: A Single-Centre Cross-Sectional Study.

Traditional metrics such as body mass index (BMI) and waist circumference (WC) fail to accurately assess the health outcomes associated with abdominal adiposity, because they neglect the intricacies of adipose tissue distribution. Notably, the variability in body composition scaled to height remains underexplored in Chinese demographics. This study introduces height-normalised indices of abdominal adiposity using computed tomography (CT) scans and further assesses their associations with various health outcomes. In a large, diverse Chinese population (n = 1054 healthy individuals; n = 1159 with dyslipidemia; n = 803 with diabetes; n = 1289 with cardio-cerebrovascular diseases; n = 1108 with cancers; and n = 509 with abnormal bone mas), abdominal CT scans were performed and allometric growth model analyses were used to derive height-normalised indices (body composition/heightβ). Logistic regression models assessed the associations between these indices and health outcomes. Distinct scaling powers were observed for visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT) and total abdominal adipose tissue (TAT), as well as for sagittal diameter (SAD), with marked sex differences. Powers for VAT were 1.786 ± 1.270 for males and 1.274 ± 0.692 for females. Powers for SAT were 2.266 ± 0.856 for males and 1.656 ± 0.497 for females. Powers for TAT were 2.141 ± 0.967 for males and 1.438 ± 0.489 for females. Powers for SAD were 0.646 ± 0.217 for males and 0.678 ± 0.141 for females. After controlling for age, BMI and WC, VAT/heightβ, TAT/heightβ and SAD/heightβ retained their significantly positive associations with the odds of health outcomes, whereas SAT/heightβ did not. Our findings endorse the clinical utility of height-normalised indices, particularly VAT/heightβ, TAT/heightβ and SAD/heightβ, in health outcomes assessment. These indices, grounded in robust empirical data, underscore the necessity of a nuanced approach in obesity-related health evaluations, advocating for a departure from conventional methods like BMI.

Well-Being and Healthcare Inequality on Bulon-Don Island in Southern Thailand-Results of a Pre-Intervention Field Survey.

Children living in an area distant from or associated with barriers to travelling to health service centres usually experience health and well-being disparities. This is a survey of child health and well-being on Bulon-Don Island, located 22 kms. from the southern mainland of Thailand, to gather essential background data before activating responses from local service provider agencies. Demographic data, physical and crude psychological health, harm to health, and living conditions of Bulon-Don children aged 1-14 years were studied and compared with the results of the corresponding national child health survey. Descriptive statistics were used for the statistical analysis of significance (p < 0.05). A total of 21 male and 41 female children (N = 62) participated in the survey after obtaining consents from parents or care providers. The islanders are Indigenous people who use their own languages and have traditional beliefs. Comparing with the children of the national survey, most children aged <5 years were found to have significantly lower height and weight according to their age (p = 0.044 and p = 0.043, respectively), whereas those aged >5 years had a similar nutritional status. In addition, there is a lack of facilities for healthy living. However, the mean total psychological and ethical standards scores were significantly higher in the 1-5 and 6-9-year-old children. Disparity of socio-political status, cultural beliefs and practices, socioeconomic basis, and geographic distance from the mainland were the social determinants and barriers of low health service accessibility for the islander children. Comprehensive child health and well-being evaluation in an enclave of isolation like this is mandatory before an integrated intervention carried out by the local healthcare and living facilities providers is implemented.

The predictive value of PCT, SP-D and 8-iso-PGF2 α for the development of severe pneumonia in children

Background: To investigate the predictive value of predictive value of procalcitonin (PCT), 8-iso-prostaglandin F2α (8-iso-PG-F2α) and pulmonary surfactant-associated protein D (SP-D) for the development of severe pneumonia in children. Methodology: Children with severe pneumonia were selected as the pneumonia group, and children with non-pulmonary respiratory diseases were selected as the control group. PCT, 8-iso-PGF2α, and SP-D were compared between the pneumonia group and the control group at admission; PCT, 8-iso-PGF2α, SP-D, and Acute Physiology and Chronic Health Evaluation (APACHE-II), Pediatric Critical Illness Score (PCIS) and Clinical Pulmonary Infection Score (CPIS) scores were compared between children with severe pneumonia with different pathogen infection types and different prognostic outcomes; and the correlation between APACHE-II, CPIS, and PCIS scores and PCT, 8-iso-PGF2α, and SP-D levels was analysed in children with severe pneumonia. Results: PCT, 8-iso-PGF2α and SP-D in pneumonia group were higher than those in control group. PCT, 8-iso-PGF2α, SP-D, APACHE-II, CPIS, and PCIS were lower in good prognosis children than in poor prognosis children. APACHE-II, CPIS, and PCIS scores were positively correlated with PCT, 8-iso-PGF2α, and SP-D levels in children with severe pneumonia (P &lt; 0.05). Conclusion: PCT, SP-D and 8-iso-PGF2α levels relate to pathogen type, illness severity and prognosis in children with severe pneumonia. They can aiding early evaluation. Keywords: severe pneumonia in children; procalcitonin; 8-isoprostane F2α; pulmonary surfactant-associated protein D; disease assessment.

8561 Association Of Alopecia And Hirsutism With Severity Of Depression In A Sample Of Hispanic Women With Polycystic Ovary Syndrome

Abstract Disclosure: C.M. Casas Loyola: None. Y.G. Rivera-Rodriguez: None. B. Marin Rodriguez: None. J.A. Roque Torres: None. L.A. Gonzalez Rodriguez: Research Investigator; Self; Lilly USA, LLC. J. Romaguera: None. Purpose: Polycystic ovary syndrome (PCOS), a highly prevalent endocrine disorder in females has been associated with several chronic diseases. Females with PCOS have been found with a higher prevalence of mental disorders. Depression and its severity have been associated with the development and progression of cardiovascular disease. We aimed to assess depression severity and its association with PCOS related comorbidities such as alopecia and hirsutism. Methods: A cross sectional study of females aged 21-45 years was conducted in the endocrinology clinics at the RCM-Clinics. PCOS was diagnosed using the Rotterdam criteria, hirsutism was defined by modified Ferriman-Gallwey score (mFG ≥ 9), alopecia was defined using the Ludwig scale and Depression using the Patient Health Questionnaire (PHQ9). Severity of depression and presence of alopecia and hirsutism were compared among groups. Results: A total of 112 patients were included in this study (85 patients PCOS+ and 27 patients PCOS-). Mean age was 32 ± 6 years. Severity of depression in PCOS- patients was: 44% none to minimal, 30% mild and 27% moderate to severe. Severity of depression in PCOS+ patients was: 28% none to minimal, 35% mild and 36% moderate to severe. Participants with alopecia and PCOS+ had a greater percentage of moderate to severe depression (58%) compared to the control group without alopecia (30%) (p value&amp;lt;0.05). No differences were observed between hirsutism and severity of depression among groups. Conclusion: Our study showed an association between alopecia and severity of depression in patients with PCOS+. The presence of hirsutism was not associated to severity of depression. Currently, there are more available treatments for hirsutism than for alopecia. For this reason, patients with hirsutism have more opportunities to manage their condition than patients with alopecia, which often require more invasive procedures. The presence of alopecia can be considered a risk factor for developing major depressive disorder in patients with PCOS. Treatment of PCOS-related abnormalities should be emphasized soon after diagnosis. Evaluation of mental health is imperative in our PCOS patients. Presentation: 6/3/2024

6973 Prospective Multicenter Registry-Based Study on Thyroid Storm: The 2016 Guidelines for the Management from the Japan Thyroid Association and Japan Endocrine Society Are Useful

Abstract Disclosure: Y. Furukawa: None. K. Tanaka: None. O. Isozaki: None. A. Suzuki: None. T. Iburi: None. K. Tsuboi: None. M. Iguchi: None. N. Kanamoto: None. K. Minamitani: None. S. Wakino: None. T. Satoh: None. S. Teramukai: None. E. Kimura: None. Y. Miyake: None. T. Akamizu: None. Context: The mortality rate in thyroid storm (TS) has been reported to be higher than 10%. Even when patients survive, some have irreversible damages. In order to improve the prognosis of patients with TS, appropriate management as well as prompt and accurate diagnosis are needed. We created the diagnostic criteria in 2012 and established guidelines for the management of TS in 2016. Objective: We aimed to evaluate the effectiveness of the 2016 guidelines for the management of TS proposed by the Japan Thyroid Association and Japan Endocrine Society. Design: Prospective registry-based study through a secure web platform. Setting: Prospective multicenter registry. Patients and Measurements: Patients with new-onset TS were registered in the Research Electronic Data Capture (REDCap) from May 1, 2018 to April 30, 2022, over four years. On day 30 after admission, clinical information and prognosis of each patient were added to the platform. On day 180, the prognosis was described. The questionnaire consisted of 176 items totally. Results: This study included 110 patients with TS (93 definite and 17 suspected). The median of Acute Physiology and Chronic Health Evaluation (APACHE) II score was 13, higher than the score in the previous nationwide survey, 10 (p=0.001). Nonetheless, the mortality rate at day 30 was 5.5%, approximately half compared with 10.7% in the previous nationwide survey (p=0.13). Lower BMI, lower left ventricular ejection fraction (LVEF) and shock were positively associated with poor prognosis at day 30. The lack of fever ≥ 38°C was surprisingly associated to the outcome. Approximately 80% of doctors followed the guidelines. The mortality rate in patients with an APACHE II score ≥ 12 for whom the guidelines were not followed was significantly higher than the rate in patients for whom the guidelines were followed (50% vs. 4.7%) (p=0.01). Conclusions: Prognosis seemed better than in the previous nationwide survey, even though disease severity was higher. The mortality rate was lower when the guidelines were followed. Thus, the guidelines are useful for managing TS. Presentation: 6/2/2024

Circulating T-lymphocyte subsets as promising biomarkers for the identification of sepsis-induced acute kidney injury.

This retrospective study investigated whether disturbances in circulating T-lymphocyte subsets could predict the incidence of acute kidney injury (AKI) and in-hospital mortality in patients with sepsis. Clinical data from patients with sepsis admitted to the intensive care unit were reviewed. Logistic regression analyses were used to identify independent predictors of in-hospital mortality and the development of AKI. Of 81 patients with sepsis, 50 developed AKI. Both non-survivors and patients with septic AKI exhibited dramatically higher Sequential Organ Failure Assessment (SOFA) and Acute Physiology and Chronic Health Evaluation (APACHE) II scores. Non-survivors exhibited more organ damage, with significantly lower levels of peripheral T-lymphocyte subsets, including total circulating lymphocytes, and CD3+, CD3+CD4+, and CD3+CD8+ T-lymphocytes. Patients with septic AKI exhibited fewer total peripheral lymphocytes and fewer CD3+, CD3+CD4+, and CD3+CD8+ T-lymphocytes, with higher serum lactate levels and lower nadir platelet counts. Independent predictors of 30-day hospital mortality included maximum SOFA and APACHE II scores, occurrence of encephalopathy, and peripheral CD3+ and CD3+CD8+ T lymphocyte counts. Moreover, the maximum SOFA score and CD3+ and CD3+CD8+ T-lymphocyte counts demonstrated good predictive power for AKI in receiver operating characteristic curve (ROC) analyses, with an area under the ROC curve of 0.810 (95% confidence interval [CI] 0.712-0.908) for SOFA score, 0.849 (95% CI 0.764-0.934) for CD3+ T-lymphocytes, and 0.856 (95% CI 0.772-0.941) for CD3+CD8+ T-lymphocytes. Patients with sepsis-induced AKI experienced T lymphopenia and increased in-hospital mortality. Higher maximum SOFA scores and reduced peripheral CD3+ and CD3+CD8+ T-lymphocyte levels were associated with in-hospital mortality and the development of AKI in patients with sepsis.

Establishment of seven lung ultrasound phenotypes: a retrospective observational study of an LUS registry

BackgroundLung phenotypes have been extensively utilized to assess lung injury and guide precise treatment. However, current phenotypic evaluation methods rely on CT scans and other techniques. Although lung ultrasound (LUS) is widely employed in critically ill patients, there is a lack of comprehensive and systematic identification of LUS phenotypes based on clinical data and assessment of their clinical value.MethodsOur study was based on a retrospective database. A total of 821 patients were included from September 2019 to October 2020. 1902 LUS examinations were performed in this period. Using a dataset of 55 LUS examinations focused on lung injuries, a group of experts developed an algorithm for classifying LUS phenotypes based on clinical practice, expert experience, and lecture review. This algorithm underwent validation and refinement with an additional 140 LUS images, leading to five iterative revisions and the generation of 1902 distinct LUS phenotypes. Subsequently, a validated machine learning algorithm was applied to these phenotypes. To assess the algorithm’s effectiveness, experts manually verified 30% of the phenotypes, confirming its efficacy. Using K-means cluster analysis and expert image selection from the 1902 LUS examinations, we established seven distinct LUS phenotypes. To further explore the diagnostic value of these phenotypes for clinical diagnosis, we investigated their auxiliary diagnostic capabilities.ResultsA total of 1902 LUS phenotypes were tested by randomly selecting 30% to verify the phenotypic accuracy. With the 1902 LUS phenotypes, seven lung ultrasound phenotypes were established through statistical K-means cluster analysis and expert screening. The acute respiratory distress syndrome (ARDS) exhibited gravity-dependent phenotypes, while the cardiogenic pulmonary edema exhibited nongravity phenotypes. The baseline characteristics of the 821 patients included age (66.14 ± 11.76), sex (560/321), heart rate (96.99 ± 23.75), mean arterial pressure (86.5 ± 13.57), Acute Physiology and Chronic Health Evaluation II (APACHE II)score (20.49 ± 8.60), and duration of ICU stay (24.50 ± 26.22); among the 821 patients, 78.8% were cured. In severe pneumonia patients, the gravity-dependent phenotype accounted for 42% of the cases, whereas the nongravity-dependent phenotype constituted 58%. These findings highlight the value of applying different LUS phenotypes in various diagnoses.ConclusionsSeven sets of LUS phenotypes were established through machine learning analysis of retrospective data; these phenotypes could represent the typical characteristics of patients with different types of critical illness.

Acute kidney injury developed in the intensive care unit: a population-based prospective cohort study in the Brazilian Amazon

The Brazilian Amazon is a vast area with limited health care resources. To assess the epidemiology of critically ill acute kidney injury (AKI) patients in this area, a prospective cohort study of 1029 adult patients of the three intensive care units (ICUs) of Rio Branco city, the capital of Acre state, were evaluated from February 2014 to February 2016. The incidence of AKI was 53.3%. Risk factors for AKI included higher age, nonsurgical patients, admission to the ICU from the ward, higher Acute Physiology and Chronic Health Evaluation (APACHE) II scores at ICU admission, and positive fluid balance > 1500 ml/24 hours in the days before AKI development in the ICU, with aOR of 1.3 (95% CI 1.03–1.23), 1.47 (95% CI 1.07–2.03), 1.96 (95% CI 1.40–2.74), 1.05 (95% CI 1.03–1.08) for each unit increase, and 1.62 (95% CI 1.16–2.26), respectively. AKI was associated with higher ICU mortality (aOR 2.03, 95% CI 1.29–3.18). AKI mortality was independently associated with higher age, nonsurgical patients, sepsis at ICU admission, presence of shock or use of vasoactive drugs, mechanical ventilation and mean positive fluid balance in the ICU > 1500 ml/24 hours, both during ICU follow-up, with aOR 1.27 (95% CI 1.14–1.43) for each 10-year increase, 1.64 (95% CI 1.07–2.52), 2.35 (95% CI 1.14–4.83), 1.88 (95% CI 1.03–3.44), 6.73 (95% CI 4.08–11.09), 2.31 (95% CI 1.52–3.53), respectively. Adjusted hazard ratios for AKI mortality 30 and 31–180 days after ICU discharge were 3.13 (95% CI 1.84–5.31) and 1.69 (95% CI 0.99–2.90), respectively. AKI incidence was strikingly high among critically ill patients in the Brazilian Amazon. The AKI etiology, risk factors and outcomes were similar to those described in high-income countries, but mortality rates were higher.

A Dataset of Visible Light and Thermal Infrared Images for Health Monitoring of Caged Laying Hens in Large-Scale Farming.

Considering animal welfare, the free-range laying hen farming model is increasingly gaining attention. However, in some countries, large-scale farming still relies on the cage-rearing model, making the focus on the welfare of caged laying hens equally important. To evaluate the health status of caged laying hens, a dataset comprising visible light and thermal infrared images was established for analyses, including morphological, thermographic, comb, and behavioral assessments, enabling a comprehensive evaluation of the hens' health, behavior, and population counts. To address the issue of insufficient data samples in the health detection process for individual and group hens, a dataset named BClayinghens was constructed containing 61,133 images of visible light and thermal infrared images. The BClayinghens dataset was completed using three types of devices: smartphones, visible light cameras, and infrared thermal cameras. All thermal infrared images correspond to visible light images and have achieved positional alignment through coordinate correction. Additionally, the visible light images were annotated with chicken head labels, obtaining 63,693 chicken head labels, which can be directly used for training deep learning models for chicken head object detection and combined with corresponding thermal infrared data to analyze the temperature of the chicken heads. To enable the constructed deep-learning object detection and recognition models to adapt to different breeding environments, various data enhancement methods such as rotation, shearing, color enhancement, and noise addition were used for image processing. The BClayinghens dataset is important for applying visible light images and corresponding thermal infrared images in the health detection, behavioral analysis, and counting of caged laying hens under large-scale farming.

A-301 Evaluation of Second-Generation Visby Medical Sexual Health Point-of-Care Test: Clinical Concordance, Analytical Error Rates, and Result Turnaround Time

Abstract Background Rapid testing for Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis may be useful for antibiotic stewardship initiatives. Our institution recently implemented the second-generation Visby Medical Sexual Health Test (Visby Gen2) for rapid diagnosis of STIs in our emergency department. Here we (1) compared result concordance of the (Visby Gen2) to the first-generation Visby Medical Sexual Health Click Test (Visby Gen1), (2) compared assay failure rates of the Visby Gen1 to Gen2 tests, and (3) compared result turnaround time (TAT) for clinically ordered rapid STI tests to central laboratory STI results. Methods Accuracy was assessed using residual clinical samples in Aptima buffer submitted for routine molecular STI testing (C. trachomatis, N. gonorrhoeae, and T. vaginalis) in the central laboratory on the Panther platform (Hologic). Aptima samples were diluted 1:33 in Visby collection buffer prior to testing on the Visby cartridge. Clinically reported results were used as reference results. Diluted samples with discordant results were re-tested on the reference method and the result from the dilution was used in calculations. Assay failure rates were calculated as the number of failed assays compared to the total assays performed. TAT for rapid and central lab testing was calculated as time of sample received in laboratory to time verified in laboratory information system. Results For Visby Gen1 we observed negative concordance of 100% (41/41) for C. trachomatis, 97.5% (39/40) for N. gonorrhoeae, and 97.1% (34/35) for T. vaginalis. Positive concordance was 91.7% (11/12) for C. trachomatis, 100% (11/11) for N. gonorrhoeae, and 100% (17/17) for T. vaginalis. For Visby Gen1 we observed a 10.5% (12/114) cartridge failure rate. For Visby Gen2, we observed negative concordance of 100% (59/59) for C. trachomatis, 100% (63/63) for N. gonorrhoeae, and 100% (55/55) for T. vaginalis while positive concordance was 100% (10/10) for C. trachomatis, 100% (6/6) for N. gonorrhoeae, and 90.9% (10/11) for T. vaginalis. The Visby Gen2 assay displayed a 4.9% (4/81) cartridge failure rate. Six weeks after implementing the Visby Gen2 assay in our ED, rapid STI panel TAT was 0.48 hours on average (n=20). In the central laboratory the average TAT was 22.31 hours (n=7892). Conclusions Assay concordance to reference method was similar for Visby Gen1 and Gen2 assays. The cartridge failure rate improved by 46.7% with the Gen2 assay which should decrease the need to repeat testing due to assay failure. Result TAT decreased by 97.8% when comparing rapid Visby results to central laboratory. Therefore, Visby STI testing using the Gen2 assay can provide accuracy and rapid results likely to facilitate more rapid patient management.

Mental Health in Education for Crisis-affected Preschool Children: Multilevel Monitoring

Introduction: The crisis in Ukraine, related to military actions, poses a significant threat to the mental health of preschool children due to their vulnerability, limited self-awareness, and perception of their surroundings, as well as the critical developmental phase characterized by the establishment of foundational personality structures. Chronic stress and trauma can disrupt normal brain development, potentially leading to delays in cognitive and emotional development in the long term. Therefore, it is essential to systematically identify and analyze the negative factors affecting the mental development of preschool children across key domains, contributing to educational deficits and developmental gaps, and to design targeted interventions to solve those emerging issues. Purpose: The study is focused on the development and implementation of strategies for supporting, preserving, and enhancing the mental well-being of preschool children residing in areas proximate to armed conflict. The research underscores the importance of early and systematic monitoring across various levels (including children, families, educators, professional associations, and early childhood education institutions, including those with alternative forms of preschool education designed to accommodate crisis conditions). Methodology: Multilevel monitoring has encompassed 3,843 children situated in conditions detrimental to their mental health and development across seven frontline regions of Ukraine (Dnipropetrovsk, Donetsk, Zaporizhzhia, Mykolaiv, Odesa, Sumy, Kharkiv). This initiative is a part of a project by "All-Ukrainian Public Organization 'Association of Early Childhood Education Professionals'", with informational support from the Ministry of Education and Science of Ukraine and is being implemented in collaboration with the United Nations (UNICEF) project "Improving Access to Early Childhood Education Services in Emergencies and Early Recovery in Ukraine." Level 1 - initial, intermediate, and summative monitoring involved establishing the baseline developmental level of senior preschool children and identifying gaps across key areas, with subsequent measurement of progress and its correlation with interventions aimed at supporting and maintaining children’s mental health. Measurement of indicators was expressed through their manifestation at the minimum and maximum points for each child, with the establishment of an average score (average score = sum of all individual scores divided by the number of children). The average score reflects the overall performance between the lowest and highest indicators across children, educators, regions, and nationally. This analysis was conducted using a web-based spreadsheet program, Google Sheets, which is part of the Google Drive office suite." Level 2 - organizational and methodological monitoring focused on evaluating the methodological and organizational aspects of the educational process as fundamental factors in preventing negative impacts on children’s mental health. This was conducted using an electronic form developed in Google Forms, utilizing the Google Sheets web-based spreadsheet program, which is part of the Google Drive office suite. Level 3 - monitoring the quality of the educational process in early childhood education institutions using the ECERS-3 methodology, which allows for the analysis of comfort levels, developmental conditions, safety, and support for the mental health of preschool children. This involves an electronic Google Form equivalent to the paper-based ECERS-3 assessment; automatic calculations are performed according to the formulas specified by the international ECERS-3 methodology (Harms et al., 2020). Results: The study of the development of senior preschool children, based on the analysis of key domains through regular psychological and pedagogical observations and the use of diagnostic tools over a period of five months, enabled the identification of early signs of stress, anxiety, and other emotional manifestations. This assessment facilitated the evaluation of children's mental health and the development of a system of effective interventions to address the identified issues. Conclusion: The study underscores the importance of identifying personal characteristics of senior preschool children and developmental gaps across key domains to organize interventions and support measures aimed at preserving mental health, ensuring comprehensive development, and mitigating negative factors in crisis conditions. The results of the multilevel monitoring are valuable for updating educational practices and adapting them to crisis situations. Addressing the identified educational losses and gaps, including those related to social-emotional development and stress resilience, allows for the development of structured programs to counteract negative impacts and facilitate the recovery of preschool children
