Higher Risk Of Mortality Research Articles

Body mass index and sarcopenia and mortality risk among older hypertensive outpatients; the Nambu Cohort Study.

Maintaining ideal body weight and muscle strength through lifestyle modification is essential for improving activities of daily living (ADL) and life expectancy in hypertensive patients. The effect of weight reduction in older patients with hypertension, however, is controversial. We evaluated the prognostic significance of body mass index (BMI) and handgrip strength (HG) in older patients with hypertension. Patients were stratified by the combination of BMI and HG. COX regression analysis was used to assess the mortality risk. A total of 563 patients (age 77 [71-84] years, 50% male, 40% frailty) were followed for a median duration of 41 (34-43) months. In total, 59 deaths occurred during the follow-up period. Validation of mortality by BMI level revealed that patients with BMI < 22 kg/m2 were likely to have higher mortality risk. Low HG, however, was associated with a 3.7-fold increased mortality risk. The risk of all-cause mortality using BMI combined with HG (adjusted hazard ratio [95% confidence interval]) was as follows: (1) Normal HG + 22 kg/m2 ≤ BMI, reference; (2) Normal HG + BMI < 22 kg/m2, 2.39 (0.12-16.46); (3) Low HG + 22 kg/m2 ≤ BMI, 4.01 (1.42-14.38); and (4) Low HG + BMI < 22 kg/m2, 4.55 (1.33-18.13). These findings demonstrate that weight reduction may deteriorate the mortality risk in older patients with hypertension, and new lifestyle modification strategies for improving ADL, quality of life, and prognosis are warranted for older patients with hypertension. We assessed the association between BMI, handgrip strength, and risk of all-cause mortality to evaluate the validity of weight reduction in older patients with hypertension.

Advanced Lung Cancer Inflammation Index as Predictor of All-Cause Mortality in ST-Elevation Myocardial Infarction Patients Undergoing Primary Percutaneous Coronary Intervention

Background: The advanced lung cancer inflammation index (ALI) is an independent prognostic biomarker used to assess inflammation and nutritional status in various cancers, heart failure, and acute coronary syndromes. This study investigates the prognostic significance of ALI in patients experiencing ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (pPCI), comparing its predictive abilities with the established Neutrophil-Lymphocyte Ratio (NLR). Methods: We conducted a retrospective analysis of 1171 patients from the Matrix Registry, encompassing demographic and clinical data for STEMI cases treated with pPCI, and ALI was determined using the formula [serum albumin (g/dL) × body mass index (kg/m2)]/NLR at the time of hospital admission. The primary outcome was all-cause mortality. Results: Of the 1171 patients, 86 died during the follow-up period. Univariate analysis identified age, female gender, smoking, hypertension, diabetes, prior myocardial infarction (PMI), lower left ventricular ejection fraction (LVEF), and reduced ALI as factors associated with mortality. Multivariate analysis confirmed age (HR: 1.1, 95% CI: 1.05–1.11, p &lt; 0.001) and PMI (HR: 2.4, 95% CI: 1.4–4.3, p = 0.001) as prominent independent predictors, alongside ALI (HR: 0.95, 95% CI: 0.92–0.97, p &lt; 0.001) and LVEF (HR: 0.98, 95% CI: 0.97–0.99, p = 0.04). An ALI cut-off of ≤10 indicated a higher mortality risk (HR: 2.3, 95% CI: 1.5–3.7, p &lt; 0.001). The area under the curve for ALI (0.732) surpassed that for NLR (0.685), demonstrating ALI’s superior predictive capability. Conclusions: ALI is an independent prognostic factor for all-cause mortality in STEMI patients undergoing pPCI, showing greater discriminatory power than NLR, particularly in patients with ALI values ≤ 10, who face a 2.3-fold higher mortality risk.

Identifying Mechanism of RSV for the Treatment of COVID-19 and Idiopathic Pulmonary Fibrosis via Suppressing Inflammation Response Through IL-17 Signaling Pathway from the Perspectives of in silico Study.

Both coronavirus disease 2019 (COVID-19) and idiopathic pulmonary fibrosis (IPF) could cause severe pulmonary injury and have extremely dismal prognoses with a high risk of mortality. Resveratrol (RSV), a natural polyphenol, has promising potential in the treatment of viral infection and pulmonary fibrosis. The purpose of this research was to investigate the unclear mechanism of RSV as an anti-COVID-19 and IPF therapy. Utilizing relevant databases, the intersection of genes related to IPF, COVID-19, and possible RSV targets was discovered. Then the obtained targets were investigated using GO and KEGG analysis, TP and PPI network analysis. Furthermore, the binding affinities between core targets and RSV were calculated using molecular docking. The 1101 COVID-19 targets, 2166 IPF targets, and 341 RSV targets intersected with 21 overlapping targets. PPI network reveals the interactions among targets and TP network reveals interactions between targets and pathways. Five targets including JUN, CCL2, CXCL8, IL6, and SERPINE1 were identified as the core targets through two network analyses. GO analysis demonstrated chemotaxis, inflammatory response and angiogenesis were the significant pathophysiological processes. Combing TP network analysis and KEGG analysis, IL-17 signaling pathway was considered as the significant pathway. Except for JUN, molecular docking showed the binding energies of other four targets were lower than -5 kcal/mol indicating intimate interactions between RSV and other targets. Our research elucidate the targets, pathways and pathophysiological processes of RSV involved in effects of anti-COVID-19 and IPF, suggesting RSV could be a therapeutic candidate for reducing infection and fibrosis.

Antifungal Resistance and Breakthrough Candidemia Among Pediatric Cancer Patients: An Emerging Threat

Abstract Background Cancer patients are at risk for candidemia. Resistance and breakthrough Candida represent an emerging threat. The study aims to analyze the clinical features, resistance patterns and breakthrough candidemia among pediatric cancer patients. Methods The retrospective study was conducted from 2014 - 2020 in children admitted to Children Cancer Hospital, Egypt. Clinical, microbiological, and outcomes were analyzed. Mortality was estimated within 30 days from Candida spp. Isolation from blood. Results Three hundred fifty (350) pediatric cancer patients were diagnosed with candidemia. The median age was four years (4 months- 18 years). Most of the patients had hematological malignancies (54%) while solid tumors represent (46%). Clinical features of the patients included neutropenia (80%), the presence of central venous line (57%), ICU admission (44%), and steroid use (43%). Non-Albicans candida was predominant (71%) compared to Candida Albicans (29%). The isolated species were: C. Albicans (29%), C.Tropicalis (29%), C. parapsilosis (21%), C. krusei (7%), C.glabrata(3%), C. guilliermondii (1.5%)and C. famata (2%). Chronic disseminated candidiasis was reported in 30 (9%) patients, with the liver being the most affected organ. Breakthrough candidemia on top of echinocandin prophylaxis was reported among 62(18%) patients with C. parapsilosis is the most common 31(50%) isolated pathogen. From 96 patients with breakthrough candidemia, all-cause mortality was reported in 32 patient (33%) while candida attributable cause of death in elven (11%) patients. Antifungal resistance was reported in 74(21%) patients: fluconazole (15%), liposomal ampho-B (6%), echinocandin (5%) and voriconazole (3%). Among 74 patients with resistant candidemia, death was reported in 24%. Echinocandin Resistant candida was a direct cause of mortality in 3(17%) patients. The overall day- 30 mortality rate was 24% (85/350 patients), while candida attributable of mortality was (10%). Patients with septic shock, ICU admission, and resistant candida had a higher mortality risk. Conclusion Echinocandin-resistant and breakthrough Candida are significant threat with a high mortality rate among pediatric cancer patients. Antifungal stewardship may be helpful. Figure 1. Resistance Pattern of Candidemia among Pediatric Cancer Patients

Women Experience Higher Rates of Mortality Following Thoracic Endovascular Aneurysm Repair

ObjectivesThoracic endovascular aortic repair (TEVAR) and complex endovascular thoraco-abdominal aneurysm repair (cEVAR) has been increasingly adopted in the treatment of thoracic and thoracoabdominal aorta aneurysms, offering a less invasive approach for patients with appropriate anatomy. Women usually present with smaller aortic diameter. However, they usually have greater aneurysm growth rates. How sex can affect postoperative and short-term outcomes after TEVAR is not well reported. The aim of this study was to assess outcomes in female versus male patients undergoing TEVAR for treatment of thoracic and thoracoabdominal aneurysms in a Medicare-linked database. MethodsWe retrospectively reviewed patients undergoing TEVAR for thoracic and thoracoabdominal aneurysm repair in the Vascular Quality Initiative (VQI) Vascular Implant Surveillance and Interventional Outcomes Network (VISION) database from 2003 to 2018. Patients were divided into males and females. Patients presented with ruptured aneurysm were excluded from the analysis. Postoperative outcomes included in-hospital stroke, myocardial infarction (MI), spinal cord ischemia, and 30-day mortality. One-year outcomes included mortality, aneurysmal rupture, and reintervention. Postoperative outcomes were assessed using multivariable logistic regression analysis and one-year outcomes were evaluated using Kaplan Meier Survival and Cox regression analyses. ResultsA total of 3,058 males and 1,843 females were available for the analysis. Female patients had smaller median aortic diameter, were more likely to be black, with chronic obstructive pulmonary disease, and chronic kidney disease, and to be symptomatic on presentation. Male patients were more likely to be on preoperative medications such as aspirin, beta-blockers, angiotensin-converting enzyme inhibitors, P2Y12 antagonists, and anticoagulants. After adjusting for potential confounders, female gender was associated with double the risk of in-hospital stroke (OR: 2.3, 95%CI ((1.5-3.7), P<0.001) and 80% increase in 30-day mortality (OR: 1.8, 95%CI (1.3-2.6), P=0.001). At one year, female gender was associated with a higher risk of mortality (HR: 1.2, 95%CI (1.05-1.4), P=0.011). There was a trend towards higher risk of reintervention (HR: 1.2, 95%CI (0.97-1.6), P=0.079). ConclusionsMortality after TEVAR seems to be higher in female patients at 30 days and up to one year of follow-up. Female patients also face a two times higher risk of in-hospital stroke. Future studies with a larger female population should aim to identify and potentially ameliorate the factors associated with these unfavorable outcomes in females.

A Nationwide Analysis in France on Sex Difference and Outcomes Following Carotid Intervention in Asymptomatic Patients.

Objective: The impact of sex on outcomes following carotid endarterectomy (CEA) and carotid artery stenting (CAS) is not fully elucidated. The aim of this study was to analyze the association between sex and outcomes of asymptomatic patients who underwent primary carotid interventions in France. Methods: This nationwide retrospective study was performed using the French National Health Insurance Information System and included asymptomatic patients who underwent primary carotid intervention over a 10-year period (1 January 2013 to 31 August 2023). Symptomatic patients and patients who had peri-operative neurologic events were excluded. The primary endpoints were the occurrence of death and stroke/transient ischaemic attack (TIA) at 30 days, 1 and 5 years after patients' discharge. Results: In total, 115,879 patients were admitted for an index CEA (29.4% women) and 6500 for CAS (29.8% women). In the CEA group, no significant sex-related difference was observed for 30-day mortality; however, women had significantly lower 1-year and 5-year mortality rates compared to men (1.9% vs. 2.6%, p < 0.001 and 7.9% vs. 11.1%, p < 0.001). In the CAS group, women had lower 30-day, 1-year and 5-year mortality (0.6% vs. 1.0%, p = 0.040, 3.8% vs. 4.9%, p = 0.048, and 10.4% vs. 15.0%, p < 0.001). A multivariate analysis showed that sex was not associated with the risk of stroke/TIA and mortality at 30 days (OR 0.84 (95% CI 0.67-1.04) and 1.27 (95% CI 0.98-1.64)). Male sex was associated with a higher risk of 1-year and 5-year mortality (OR 1.24 (95% CI 1.13-1.36) and 1.25 (95% CI 1.18-1.31)), but a lower risk of stroke/TIA than female sex. Conclusions: No significant sex-related difference was observed at 30 days in patients being discharged alive and without peri-operative neurologic events. Male sex was associated with a higher risk of mortality but a lower risk of stroke/TIA at 1 and 5 years.

Investigation of Biochemical and Inflammatory Markers in COVID-19 Patients Hospitalized in the Intensive Care Unit: An Observational Study in Northern Iran

Background: Since the first documentation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), there has been a notable emphasis on it in a brief period, especially as the mortality rate and confirmed cases steadily rise. The rapid and accurate laboratory identification of an ongoing COVID-19 infection is essential for efficient pandemic control. For diagnostic purposes, various testing methods have been developed to detect the severity of COVID-19. These diagnostic methods play a crucial role in identifying and managing the spread of the virus within communities worldwide. Methods: This cross-sectional observational study was conducted from February to June 2020, spanning four months. Patient clinical records and laboratory biomarkers data were collected. Results: In this study, 263 patients were involved, with an average age of 59.38 ± 15.26 years, and 51.3% of them (135 patients) were male. The typical hospital stay was 9.25 ± 6.9 days. The patients were divided into three groups: Those who survived (49.4%), those receiving treatment (4.9%), and those who did not survive (45.6%), with all treated patients surviving. An important connection was observed between serum lactate dehydrogenase (LDH), creatine phosphokinase (CPK), urea, leukocytosis, lymphopenia, high polymorphonuclear neutrophil (PMN) counts, and poor patient outcomes (P-value &lt; 0.05). Elevated aspartate transaminase (AST) levels also showed a close relationship with adverse outcomes (P-value = 0.05). Furthermore, most patients with hyponatremia, high fasting blood glucose, and elevated serum creatinine levels did not survive, despite lacking statistical significance. Conclusions: Serum biomarkers serve as prognostic indicators for the severity of COVID-19 patients. Leveraging these markers aids in promptly diagnosing patients at high mortality risk and facilitates more effective treatments in the disease's initial phases. These biomarkers can help healthcare providers identify patients at higher risk of complications and guide the implementation of targeted interventions to improve patient outcomes.

Positive effects of magnesium supplementation in metabolic syndrome.

Recent data show that magnesium supplementation decreases systolic and diastolic blood pressure values depending on the blood pressure levels and improves metabolic parameters in cardiovascular disease. In this context, we conducted a prospective, randomized, double-blind study on serum and ionized magnesium, systolic and diastolic blood pressure values, interleukin-6, vitamin D, and metabolic profile in 27 patients (13 male/14 female, age: 60.2±12.5 years) with metabolic syndrome. All patients received 400 mg of oral magnesium supplementation daily. Parameters were measured before and after 6 and 12 weeks of treatment. 27 patients served as controls without additional magnesium treatment (10 male/17 female, age: 64.6±13.2 years). There was no significant change in serum magnesium after 6 and 12 weeks of magnesium supplementation and in controls. Ionized magnesium significantly increased from 0.56±0.05 to up to 0.63±0.08 mmol/L (mean ± SD) (p<0.01). The ionized Ca++/Mg++ ratio was significantly increased at baseline in about 32% of all patients; after 12 weeks of magnesium supplementation, the Ca++/Mg++ ratio decreased significantly from 2.32±0.22 to 2.04±0.24 at the end of the study (mean ± SD, p<0.05). In the magnesium-treated group, there was a significant decrease in systolic and diastolic blood pressure values after 12 weeks (systolic: 134.6±6.8 to 126.3±5.6 mmHg, diastolic: 84.1±3.9 to 79.4±1.6 mmHg) (mean ± SD) (p<0.01). Additional magnesium supplementation decreased interleukin-6 values significantly from 4.94±3.30 to 4.53±6.89 pg/mL after 6 weeks to 3.01±1.32 pg/mL after 12 weeks (mean±SD) (p<0.01). In the control group, interleukin-6 was 3.73±4.36 pg/mL before the start of the supplementation, 4.87±4.35 pg/mL after 6 weeks, and 4.41±3.15 pg/mL after 12 weeks (means ± SD) (n.s.). In patients receiving magnesium supplementation, vitamin D levels significantly improved from 17.93±8.96 to 24.41±10.20 ng/mL (mean±SD) (p<0.05). HbA1c and serum cholesterol values improved under magnesium therapy, but the improvement did not reach significance. For statistical analysis, Mann-Whitney-U-Test was used. Using supplementation with 400 mg magnesium for 12 weeks in patients with metabolic syndrome, ionized magnesium concentrations significantly increased, while serum magnesium did not change significantly. Both systolic and diastolic blood pressure values decreased significantly in the magnesium-treated group. Magnesium supplementation also significantly decreased interleukin-6 levels and increased vitamin D in patients. HbA1c and cholesterol levels improved with magnesium supplementation, but the improvement did not reach significance. The anti-inflammatory effects of magnesium as well as anti-arteriosclerotic effects of magnesium therapy are beneficial for patients with metabolic syndrome at high risk of cardiovascular disease and mortality.

Application of deep learning-based fuzzy systems to analyze the overall risk of mortality in glioblastoma multiforme

Abstract Glioblastoma multiforme (GBM) is the most aggressive brain cancer in adults, with 3.2-3.4 cases per 100 thousand. In the US, brain cancer does not rank in the top 10 causes of death, but it remains in the top 15. Therefore, this research proposes a fuzzy-based GRUCoxPH model to identify missense variants associated with a high risk of all-cause mortality in GBM. The study combines various models, including fuzzy logic, Gated Recurrent Units (GRUs), and Cox&amp;#xD;Proportional Hazards Regression (CoxPh), to identify potential risk factors. The dataset is derived from TCGA-GBM clinicopathological information and mutations to create four risk score models: GRU, CoxPH, GRUCoxPHAddition, and GRUCoxPHMultiplication, analyzing 9 risk factors of the dataset. The Fuzzy-based GRUCoxPH model achieves an average accuracy of&amp;#xD;86.97%, outperforming other models. This model demonstrates its ability to classify and identify missense variants associated with mortality in GBM, potentially advancing cancer research.&amp;#xD;

Gender differences in the relationship between the systemic immune-inflammation index and all-cause and cardiovascular mortality among adults with hypertension: evidence from NHANES 1999-2018.

There are gender differences in hypertension and the effect of gender on the relationship between systemic immune-inflammation index (SII) and mortality in hypertensive patients is unclear. Hypertensive patients (n=7444) from ten cycles of the National Health and Nutrition Examination Survey (NHANES) spanning 1999 to 2018 were enrolled in this study. The maximally selected rank statistics method was employed to identify the optimal cut-off value for the SII. Survey-weighted Cox regression analysis was utilized to explore the links between SII and all-cause and cardiovascular mortality. Kaplan-Meier method and time-dependent receiver operating characteristic curve analysis was conducted to assess the predictive accuracy of SII for mortality. Whether SII was considered as a numerical variable or as a binary variable (higher- and lower-SII groups), higher SII levels were associated with a higher risk of all-cause and cardiovascular mortality in female hypertensive patients (all P < 0.001), but no such association was observed in the males. The area under the curve of the SII was 0.602, 0.595, and 0.569 for 3-, 5-, and 10-year all-cause mortality, respectively, in females, but was 0.572, 0.548, and 0.554 in males. High SII levels interacted with the poverty income ratio and physical activity to affect mortality in the male population (P for interaction < 0.05), and there was an interaction between race and SII in the female cardiovascular mortality rate (P for interaction < 0.05). Higher levels of SII may be closely related to the high risk of all-cause and cardiovascular mortality in hypertensive patients, and the results showed that this relationship is more significant and stable in the female group. High SII interacts with PIR, physical activity, and race to affect the mortality rate in different gender populations.

SARS-CoV-2 RNAemia as a reliable predictor of long-term mortality among older adults hospitalized in pulmonary intermediate care units: a prospective cohort study

BackgroundSARS-CoV-2 viremia is associated with disease severity and high risk for in-hospital mortality. However, the impact of SARS-CoV-2 viremia on long-term outcomes in hospitalized patients with COVID-19 is poorly understood.MethodsWe conducted a prospective cohort study and recruited a group of older adult patients with COVID-19 admitted to pulmonary intermediate care units of Peking University Third Hospital during December 2022 and January 2023. The plasma level of SARS-CoV-2 RNA was determined by a standardized RT-PCR technique, and SARS-CoV-2 RNAemia was defined as a plasma viral load ≥ 50 copies/ml. In-hospital and follow-up (180-day) outcome data were collected.ResultsA total of 101 patients with an average of 80.4 years were recruited, and 63.4% of them were severe or very severe cases. Twenty-eight patients (27.7%) had SARS-CoV-2 RNAemia, with a median viral RNA load of 422.1 [261.3, 1085.6] copies/ml. Patients with SARS-CoV-2 RNAemia were more likely to develop critical cases and had a higher incidence of sepsis. Accordingly, they had a higher 180-day mortality (57.1% vs. 19.7%, P < 0.001), as well as in-hospital mortality (50.0% vs. 13.7%, P < 0.001), independent of age, disease severity, sepsis, lymphocyte count and C-Reactive protein. In addition, the risk for 180-day mortality increased with the SARS-CoV-2 RNA load in plasma. Plasma cytokines, including IL-6, IL-8 and IL-10, were higher in patients with SARS-CoV-2 RNAemia.ConclusionsOur study indicates that SARS-CoV-2 RNAemia serves as a useful biomarker for predicting mortality, especially long-term mortality, in older adult patients hospitalized in pulmonary intermediate care units.Trial registrationChinese Clinical Trial Registry website (No. ChiCTR2300067434).

Spontaneous Wing Tip Edema in Captive Birds of Prey: Review of 41 Cases in the United Kingdom (2004-2022).

There is limited literature regarding wing tip edema (WTE) in raptors, and much of our current understanding of the condition is based on anecdotal reports. The aims of this retrospective study were to describe the clinical features of WTE in birds of prey, to identify prognostic factors for return to flight and patient survival following diagnosis, and to develop and assess the clinical significance of a novel WTE grading system. Between 2004 and 2022, 41 cases of WTE were identified in 39 captive birds. No cases were found in wild birds. Harris's hawks (Parabuteo unicinctus), lanner falcons (Falco biarmicus), and peregrine falcons (Falco peregrinus) had the highest frequencies of WTE, and all cases presented between October and May. Increasing days of air frost per month and colder median monthly temperatures were significant risk factors for the development of WTE. Of the cases where patient outcomes were known, 23/31 (74.2%) cases returned to normal flight and 29/34 (85.3%) cases survived. End-stage disease, represented by primary flight feather loss and metacarpal ischemic (dry) gangrene, and enalapril use were associated with poor patient outcomes. Presentation within 24 hours of disease onset, isoxsuprine use, and physiotherapy were associated with improved patient outcomes. This study showed that WTE is an infrequently encountered but clinically significant condition in captive raptors and is associated with an overall high morbidity and moderate mortality risk.

Clinical features and prognostic factors of AIDS-associated diffuse large B-cell lymphoma

To explore the general clinical features and treatment outcomes of patients with AIDS-related diffuse large B-cell lymphoma (AIDS-DLBCL) and provide a theoretical basis for diagnosis and treatment, survival prognosis, prevention and management of AIDS-DLBCL patients. AIDS-DLBCL patients who received combined antiretroviral therapy (cART) at Changsha First Hospital from January 2017 to January 2020 were selected in this study. The survival curves were plotted using the Kaplan-Meier method, and the Cox proportional hazards regression model was used to analyze the association between AIDS-DLBCL specific variables and progression-free survival and overall survival. Correlation analysis was conducted based on the clinical features of the patients. A total of 50 AIDS-DLBCL patients were included. Their median age (Q1, Q3) was 52 (44, 59) years, of whom 46 (92%) were male. About 20 (40%) patients received treatment with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP), while 23 patients (46%) received treatment with rituximab combined with cyclophosphamide, doxorubicin, vincristine, and prednisone (RCHOP). Survival curve analysis showed that the 2-year progression-free survival rate and overall survival rate of AIDS-DLBCL patients were 56.9% and 61.6%, respectively. Patients with RCHOP protocol combined with EBV-DNA≥1 000 copies/ml had higher progression-free survival rate (χ2=3.844, P=0.043) and overall survival rate (χ2=4.662, P=0.031) than those with CHOP protocol combined with EBV-DNA≥1 000 copies/ml. A multivariate analysis showed that male (HR=2.70, 95%CI:1.10-6.80), EB viral load≥1 000 copies/ml (HR=1.75, 95%CI:1.12-2.84), HIV-RNA≥200 copies/ml (HR=4.64, 95%CI: 1.73-12.15), ECOG PS score of 2 to 4 points (HR=3.54, 95%CI:1.62-7.33), and international prognostic index (IPI) score of 3 to 5 points (HR=5.21, 95%CI:1.39-20.14) were at a higher risk of disease progression. Patients with EB viral load≥1 000 copies/ml (HR=0.07, 95%CI:0.05-0.93) on the RCHOP regimen had a small risk of disease progression. Males (HR=2.87, 95%CI:1.65-9.17), EB viral load≥1 000 copies/ml (HR=1.61, 95%CI:4.02-9.36), HIV-RNA≥200 copies/ml (HR=1.19, 95%CI:1.58-2.74), ECOG PS score of 2 to 4 (HR=6.42, 95%CI:2.55-14.33), IPI score of 3 to 5 points (HR=2.78, 95%CI:1.41-12.96) had a high risk of mortality. Patients with EB viral load≥1 000 copies/ml (HR=0.24, 95%CI:0.64-0.90) on the RCHOP regimen had a low risk of mortality. In summary, males, ECOG physical status score of 2 to 4 points, IPI score of 3 to 5 points, EB viral load≥1 000 copies/ml and HIV viral load≥200 copies/ml are risk factors affecting progression-free survival and overall survival of AIDS-DLBCL patients. RCHOP regimen combined with EB viral load≥1 000 copies/ml is a protective factor affecting progression-free survival and overall survival in AIDS-DLBCL patients.

7839 Assess Management of Adrenal Insufficiency in Melanoma Patients Treated with Cancer Immunotherapy

Abstract Disclosure: W. Lin: None. L. Min: None. Despite high prevalent of adrenal insufficiency in melanoma patients treated with cancer immunotherapy, no study has examined the management of adrenal insufficiency in these patients. We performed this retrospective, longitudinal cohort study at Mass General Brigham, Boston, aims to characterize the management of adrenal insufficiency in melanoma patients. Patients were identified through our RPDR search tool, and medical record reviews were conducted. Three patient groups were analyzed: Melanoma with secondary adrenal insufficiency group (Mel_SAI, n=74), Melanoma matched control group (Mel_Con, n=69), and Pituitary macroadenoma-related adrenal insufficiency matched control group (Pit_Con, n=37). We compared self-perceived quality of life, glucocorticoid replacement dose, and clinic visit. Mel_SAI patients exhibited significantly higher incidences of anxiety (43.1%, 95%CI: 32.3-54.6), fatigue (73.6%, 95%CI: 62.4-82.4), pain (58.3%, 95%CI: 46.8-69.0), and insomnia (36.1%, 95%CI: 26.0-47.6), as compared to Pit_Con group (21.6%, 11.4-37.2; 24.3, 13.4-40.1; 29.7%, 17.5-45.8; 5.4%, 1.5-17.7, respectively). The initial hydrocortisone dose was higher for Mel_SAI (30mg qd, 95%CI: 20.5-25.1) compared to Pit_Con (15mg qd, 95%CI: 12.8-18.3). Additionally, the Mel_SAI group had fewer endocrinology clinic visits (3, 95%CI: 3.40-5.04) than the Pit_Con group (9, 95%CI: 7.35-10.9). Subgroup analysis indicated a higher mortality risk (HR 2.61, 95% CI 1.11-6.13) in Mel_SAI patients with fewer than three endocrinology visits over five years. Compared to the Mel_Con group, Mel_SAI patients also showed higher incidences of fatigue (71.6%, 95%CI: 60.5-80.6; Mel_Con: 55.1%, 95%CI: 43.4%-66.2%), but lower rates of depression (25.7%, 95%CI: 17.1-36.7; Mel_Con: 43.5%, 95%CI: 32.4-55.2) and appetite loss (24.3%, 95%CI: 16.0-35.2; Mel_Con: 47.8%, 95%CI: 36.4-59.4). No significant difference in other self-perspective symptoms. Furthermore, Mel-SAI patients had more oncological clinic visits (71, 95%CI: 74.0-109.2) than those in the Mel_Con group (41, 95%CI: 42.1-64.1). Our study suggests that most self-perceived quality of life in the Mel_SAI group is related to melanoma rather than adrenal insufficiency. Therefore, a higher initiating dose of hydrocortisone in melanoma patients with adrenal insufficiency may not be necessary. However, increasing endocrine clinic visits in cancer patients with cancer immunotherapy-related adrenal insufficiency may improve their survival outcomes. Presentation: 6/3/2024

8473 Prediabetes As A Risk Factor For All-Cause And Cause-Specific Mortality In 117,227 Diabetes-Free Adults In Mexico City

Abstract Disclosure: C.A. Fermin-Martinez: None. O.Y. Bello-Chavolla: None. N.E. Antonio-Villa: None. D. Ramirez Garcia: None. J.A. Seiglie: None. Background: Prediabetes has been consistently linked to high risk of diabetes progression, cardiovascular disease, and all-cause mortality. However, no large-scale studies have been conducted in Mexico or Latin America examining these associations despite the growing prevalence of this condition in low- and middle-income countries. Methods: We analyzed data from 117,227 adults without diabetes aged ≥35 years who participated in the Mexico City Prospective Study (1998-2004). Individuals with self-reported chronic comorbidities at baseline were excluded to mitigate reverse causation. Participants were followed-up until January 1st, 2021 for cause-specific mortality. We defined prediabetes according to the American Diabetes Association (ADA, HbA1c ≥5.7%) and the International Expert Committee (IEC, HbA1c ≥6.0%) definitions. Cox regressions were used to estimate prediabetes-related risk for all-cause and cause-specific mortality, stratified by sex and age-at-risk and adjusted for municipality of residence, education level, physical activity, smoking, alcohol consumption, and adiposity markers. Results: Compared to individuals with normoglycemia, participants with IEC-defined prediabetes had a higher risk of all-cause (HR 1.16, 95%CI 1.05-1.27), cardiac (HR 1.29, 95%CI 1.05-1.59), renal (HR 1.59, 95%CI 1.14-2.23), and acute diabetes-related (HR 2.60, 95%CI 1.52-4.43) mortality at ages 40-74 years compared to normoglycemic participants. HRs were attenuated at older ages. Results were broadly similar irrespective of the definition of prediabetes except for cardiac deaths, in which the risk was non-significant using the ADA cutoff (HR 1.14, 95%CI 0.99-1.31). Long-term effects of prediabetes (IEC-defined) accounted for ∼37% of renal deaths and ∼61% of acute diabetes-related deaths in Mexican adults without diabetes at baseline. Conclusion: Prediabetes is an important risk factor that accounts for a significant fraction of all-cause, cardiac, renal, and acute diabetes-related deaths among Mexican adults, particularly when using the higher threshold of IEC-defined prediabetes. Endpoint-driven definitions of prediabetes should be considered for widespread implementation of screening and preventive strategies that minimize overdiagnosis and improve cardiometabolic outcomes in this population.

Background: The association of dependent Cushing's ACTH Syndrome with certain types of cancer is well known, such as small cell lung cancer, enteropancreatic tumors, thymoma, thyroid cancer, however, in association with cervical cancer there are almost no cases described. Clinical Case: A 39-year women, showed about 2.5 years ago with abnormal uterine bleeding, being submitted to colposcopy with the presence of exophytic, friable and hardened lesion in the anterior region of the cervix. Biopsies revealed adenocarcinoma, endometrioid type and immunohistochemistry (IHC) positive for: Ki-67 80%, vimentin and CEA. Patient underwent initial treatment with chemotherapy and radiotherapy, losing follow-up with Oncology. After 1 year, the patient was admitted to a hospital with behavioral alteration, including suicidal ideation, muscle weakness, breast enlargement and hair growth on the face. On physical examination, there was the presence of hypertension, hyperglycemia, centripetal obesity, legs edema and hirsutism. Due to the typical symptoms, the hypothesis of Cushing's Syndrome was made and laboratory and imaging tests were requested. Initial tests: K 1.9 mmol/L (3.5-5.6 mmol/L), Na 146 mmol/L (137-145 mmol/L), TSH 0.25 uIU/mL (0.49-5.58 uIU/mL/mL), free T4 0.78 ng/dL (0.89-1.53 ng/dL), pH 7.57 (7.36-7.41), HCO3 43.1 mmol/L (23-27 mmol/L), LH 0.15 mIU/mL (1.9-12.5 mIU/mL), FSH 1.02 mIU/mL (2.5-10 mIU/mL), estradiol 84.1 pg/mL (&amp;lt; 32.2 pg/mL), ACTH 365.0 pg/mL and 98.6 pg/mL (&amp;lt; 46 pg/mL), cortisol &amp;gt; 75 ug/dL (5.27-22.5 ug/dL), urinary cortisol 3790 ug/24h (4-60 ug/24h), testosterone 333 ng/dL (12 - 59 ng/dL), free testosterone 10.12 ng/dL (0.08-1.1 ng/dL), dehydrotestosterone 1,620 pg/mL (&amp;lt; 596 pg/mL), androstenedione &amp;gt; 10 ng/mL (0.3-3.3 ng/mL). The dosages of ACTH and cortisol were performed after the dexamethasone suppression test and a pituitary MRI was normal. The MRI of the abdomen and pelvis showed multiple solid nodular lesions in liver with varying sizes compatible with metastatic disease, in addition, showed the increase in the bilateral volume of the adrenals. Liver biopsy was performed exhibiting carcinoma infiltration with IHC compatible with neuroendocrine tumor, positive for: CDX-2, SATB2, chromogranin A and synaptophysin (waiting for ACTH). Other primary sites were ruled out. The patient was initially treated with Etomidate in a continuous infusion, without tolerance and little control of hypercortisolism, after initiating Ketoconazole which was suspended due to hepatotoxicity, and then underwent bilateral adrenalectomy. Unfortunately, she died 4 days after surgery due to septic shock. Conclusion: This case report brings a very rare association of Cushing's syndrome by ectopic ACTH due to cervical cancer, with less than 10 cases reported, in which we highlight the diagnostic difficulty, the complexity of treatment and the high risk of morbidity and mortality.

Psychosocial burden and quality of life of parents with children with univentricular hearts compared to ASD parents and parents of heart-healthy children.

Patients with univentricular hearts can only be palliated by a staged surgical procedure that carries a high morbidity and mortality risk. The aim of this study was to examine the emotional demands, psychosocial burden, and quality of life of parents with children with univentricular hearts compared to parents of children with a simple heart defect, those with no heart defect and children with chronic diseases. An anonymous questionnaire was created to interview parents about their quality of life, stressors, needs, strategies for coping with illness, and partnership satisfaction. 73 families participated in the study. Parents of children with univentricular hearts experience a significantly higher psychosocial burden, limitations in daily life, and distress in family interactions, as well as greater emotional distress compared to the other study groups. When comparing the families of children with other chronic diseases (e.g. cystic fibrosis, chronic arthritis and diabetes), these differences remained significant. The study confirms a higher psychosocial burden, restrictions in daily life and a lower quality of life of parents with children with univentricular hearts, compared to parents of children with simple heart defects and parents of heart-healthy children or those with other chronic diseases. Since this condition persists until adolescence and adulthood, the families are exposed to special challenges and stresses throughout their lives. This has yet to be adequately addressed in the management of these families.

Association of metabolic score for visceral fat with all-cause mortality, cardiovascular mortality, and cancer mortality: A prospective cohort study.

Our study aimed to evaluate the association between the metabolic score for visceral fat (METS-VF) and mortality. We conducted a cohort study comprising 11,120 participants. We employed weighted multivariable Cox regression analysis to assess the relationship between METS-VF and mortality. Restricted cubic spline analyses were used to investigate potential non-linear associations. Receiver operating characteristic curves were used to evaluate the predictive value of METS-VF and other obesity-related indicators for mortality. Subgroup analysis and sensitivity analysis were performed to confirm the robustness of the results. Mendelian randomization analysis was utilized to assess potential causality. Over a median follow-up duration of 83 months, a total of 1014 all-cause deaths, 301 cardiovascular deaths,and 262 cancer deaths occurred. For every 0.2-unit increase in METS-VF, the hazard ratios(HRs)of all-cause mortality, cardiovascular mortality, and cancer mortality were 1.13 [95% confidence interval (CI): 1.06, 1.20], 1.18 (95% CI: 1.06, 1.31), and 1.13 (95% CI: 1.03, 1.25), respectively. In addition, restricted cubic spline analyses revealed no significant non-linear associations between METS-VF and all-cause mortality, cardiovascular mortality, and cancer mortality. In multivariate Cox regression models, hazard ratios of all-cause mortality, cardiovascular mortality and cancer mortality were higher in the highest METS-VF group compared to the reference group. Subgroup and sensitivity analyses confirmed that our results were robust. Receiver operating characteristic curves indicated that METS-VF predicted mortality better than other obesity-related indicators. Mendelian randomization analysis confirmed significant causal relationships. METS-VF was positively associated with all-cause mortality, cardiovascular mortality, and cancer mortality. These findings suggest that METS-VF could serve as a straightforward, reliable, and cost-effective marker for identifying individuals at high risk of mortality.

Coronary artery bypass grafting in octogenarians: a nomogram for predicting all-cause mortality

BackgroundThe benefits and risks of coronary artery bypass grafting (CABG) in octogenarians remain unclear. This study aimed to identify the predictors of increased risk of all-cause mortality in octogenarian patients after CABG.MethodsWe retrospectively analyzed the data of 1636 octogenarians who underwent isolated elective on-pump CABG between 2007 and 2016. The primary endpoint was mortality from any cause. The Kaplan–Meier curve was generated for mortality. A univariate Cox regression was performed for preprocedural and procedural variables. The Akaike information criterion (AIC) using the Cox proportional hazard model was applied to determine the strongest predictors. We designed a nomogram based on the selected variables to calculate the mortality risk after one, five, and ten years. The bootstrap resampling based on the C-index was performed to validate the final model. Calibration plots were created at different time points.ResultsThe mean age of the patients was 82.03 years (SD = 1.74), and 74% were male. In a median follow-up of 9.2 (95% CI 9.0,9.5) years, 626 (38.2%) patients died. After the selection of best predictors based on AIC, the multivariable Cox regression showed that ejection fraction < 40 (HR 1.41, 95% CI 1.21–1.65, P < 0.001), two-vessel disease (HR: 0.59, 95% CI 0.40–0.89, P = 0.012), peripheral vascular disease (HR 1.52, 95% CI 1.05–2.21, P = 0.027), and valvular heart disease (HR 1.45, 95% CI 1.24–1.69, P < 0.001) were the significant predictors of all-cause mortality.ConclusionOctogenarians who undergo CABG have a high mortality risk, influenced by several preprocedural and procedural risk factors. The proposed nomogram can be considered for optimizing the management of this vulnerable age group.Clinical registration number IR.TUMS.THC.REC.1400.081.Graphical abstract
