Objective: To investigate the relationship between the changes of immune indexes and prognosis in patients with sepsis.
Methods: Based on the hospitalization information from 2008 to 2019 in the American Medical Information Mart for Intensive Care-IV v2.0 (MIMIC-IV v2.0), the hospitalized data including CD3 count, CD4 count, CD8 count, CD4/CD8 ratio, immunoglobulins (IgA, IgG, IgM) levels and lymphocyte counts, gender, age, body mass index (BMI), sequential organ failure assessment (SOFA), and prognosis of patients with coronary heart disease, hypertension, diabetes mellitus, underlying diseases, and 28-day prognosis were collected. The immunological indexes affecting the prognosis of patients with sepsis were compared and analyzed. The receiver operator characteristic curve (ROC curve) was drawn to analyze the value of immunological indexes in predicting the 28-day prognosis of patients with sepsis.
Results: A total of 33 745 patients were enrolled in the study, including 1 509 cases of sepsis and 32 236 cases without sepsis. Among the patients with sepsis, there were 1 084 cases alive and 425 cases died within 28 days. BMI (kg/m: 33.25±28.71 vs. 28.90±15.28) and IgA levels within 3 days and 7 days after admission in sepsis group were significantly higher than those in the non-sepsis group [within 3 days after admission: (275.01±216.96) mg/L vs. (85.99±75.76) mg/L; within 7 days after admission: (275.01±216.96) mg/L vs. (85.99±75.76) mg/L, all P < 0.05]. CD3 count, CD8 count within 3 days and 7 days after admission in sepsis group were significantly lower than that in the non-sepsis group [within 3 days after admission: CD3 counts were (1 080.74±849.23)/μL vs. (1 242.91±889.24)/μL, CD8 counts were (558.07±368.77)/μL vs. (625.07±529.66)/μL; within 7 days after admission: CD3 counts were (1 079.69±850.61)/μL vs. (1 242.48±889.23)/μL, CD8 counts were (556.70±467.23)/μL vs. (624.93±429.78)/μL, all P < 0.05]. The proportion of patients with hypertension, diabetes and coronary heart disease were significantly higher than those in the non-sepsis group [hypertension: 10.07% (152/1 509) vs. 2.47% (796/32 236), diabetes: 50.10% (756/1 509) vs.15.18% (4 895/32 236), coronary heart disease: 31.21% (471/1 509) vs. 19.19% (6 186/32 236), all P < 0.05]. In the sepsis group, the CD3 count, CD4 count and CD4/CD8 ratio in the survival group were significantly higher than those in the death group within 3 days and 7 days after admission [within 3 days after admission: CD3 counts were (1 127.20±857.14)/μL vs. (938.26±810.50)/μL, CD4 counts were (559.76±507.18)/μL vs. (338.75±267.11)/μL, CD4/CD8 ratios were 1.87±0.80 vs. 1.02±0.12; within 7 days after admission: CD3 count were (1 124.01±810.53)/μL vs. (943.78±808.21)/μL, CD4 count were (559.56±507.36)/μL vs. (341.95±266.56)/μL, CD4/CD8 ratios were 1.88±0.79 vs. 1.03±0.13, all P < 0.05]. The area under the ROC curve (AUC) of CD4/CD8 ratio within 3 days after admission in predicting the prognosis of septic patients at 28 days was 0.615 [95% confidence interval (95%CI) was 0.555-0.671], the sensitivity was 70.83%, and the specificity was 52.49%.
Conclusions: Hypertension, coronary heart disease and diabetes are more likely to induce sepsis. The changes of immune indexes in patients with sepsis will occur in the early stage. Early CD4/CD8 index can predict the prognosis of patients with sepsis to a certain extent.

Background: Bronchiolitis is the most common cause of lower respiratory tract infection (LRTI) in the first year of life. We analyzed the association between complete blood count (CBC), c-reactive protein (CRP), and novel inflammatory indexes (NLR, PLR, MLR, ELR, LMR, NPR, LPR, LNR, PNR, SII, SIRI) in predicting bronchiolitis severity at hospital admission.
Methods: We retrospectively collected data from 95 infants hospitalized for bronchiolitis in a third-level hospital during three epidemic seasons.

Background: This study compares organ dysfunction, treatment strategies, and unfavorable outcome rates between pregnant and nonpregnant women admitted to the ICU with severe COVID-19, highlighting the increased susceptibility of pregnant women to respiratory infections due to physiological changes.
Methods: A retrospective, age-matched study was conducted at a referral center specializing in critical care for pregnant women. Data from 14 pregnant/postpartum and 11 nonpregnant women were analyzed at ICU admission and on days 3, 5, and 7.

Fungal infections (FIs) are widespread globally, affecting both immunocompromised and immunocompetent children, with varying clinical implications based on age and comorbidities. In immunocompromised children, particularly those with hematologic oncological conditions, FI leads to substantially longer hospital stays and increased in-hospital mortality, with reported rates ranging from 15% to 20%. Our study aims to analyze the epidemiological trends of fungal infections in the pediatric population within a specific region of Italy.

: Hypoxic-ischemic encephalopathy (HIE) in late preterm and term neonates accounts for neonatal mortality and unfavorable neurodevelopmental outcomes in survivors despite therapeutic hypothermia (TH) for neuroprotection. The circumstances of death in neonates with HIE, including involvement of neonatal palliative care (NPC) specialists and neurodevelopmental follow-up at 18-24 months in survivors, warrant further evaluation. : A retrospective multicenter cohort study including neonates ≥ 35 weeks gestational age with moderate to severe HIE receiving TH, registered in the Swiss National Asphyxia and Cooling Register between 2011 and 2021.
