AI Article Synopsis
- This study looked at 47 COVID-19 patients in an ICU in Wuhan, China, to identify risk factors for mortality.
- Results showed that patients who died had higher rates of septic shock and worse scores on assessment scales like SOFA and APACHE II compared to survivors.
- Key findings indicated that a higher SOFA score and a lower lymphocyte count at admission were significant independent risk factors for poor outcomes in these patients.
Article Abstract
Background: Coronavirus disease 2019 (COVID-19) is a potentially life-threatening contagious disease which has spread all over the world. Risk factors associated with the clinical outcomes of COVID-19 pneumonia in intensive care unit (ICU) have not yet been well determined.
Methods: This was a retrospective, single-centered, observational study, in which 47 patients with confirmed COVID-19 were consecutively enrolled from February 24 to April 5, 2020. The patients were registered from the ICU of Leishenshan Hospital in Wuhan, China. Clinical characteristics and outcomes were collected and compared between survivors and non-survivors. Multivariable logistic regression was performed to analyze the risk factors of death in patients with COVID-19.
Results: The study cohort included 47 adult patients with an average age of 70.55±12.52 years, and 30 (63.8%) patients were men. Totally 15 (31.9%) patients died. When compared to survivors, nonsurvivors showed a higher proportion of septic shock [6 (40%) patients vs. 3 (9.4%) patients], disseminated intravascular coagulation [3 (21.4%) vs. 0], and had higher score of APACHE II (25.07±8.03 vs. 15.56±5.95), CURB-65 {3 [2-4] vs. 2 [1-3]}, Sequential Organ Failure Assessment (SOFA) {7 [5-9] vs. 3 [1-6]}, higher level of D-dimer {5.74 [2.32-18] vs 2.05 [1.09-4.00]} and neutrophil count {9.4 [7.68-14.54] vs. 5.32 [3.85-9.34]}. SOFA score (OR 1.47; 95% CI: 1.01-2.13; P=0.0042) and the lymphocyte count (OR 0.02; 95% CI: 0.00-0.86; P=0.042) on admission were independently risk factors for mortality. Patients with higher lymphocyte count (>0.63×109 /L) and lower SOFA score (≤4) on admission had a significantly better prognosis than those with lower lymphocyte count (≤0.63×109 /L) and higher SOFA score (>4) in overall survival.
Conclusions: Higher SOFA score and lower lymphocyte count at admission were connected with poor prognosis of patients with COVID-19 in ICU. Lymphocyte count may serve as a promising prognostic biomarker.

Purposes: We analyzed the acute-phase response in unilateral thyroidectomy by comparing the transoral endoscopic thyroidectomy vestibular approach (TOEVA) with the minimally invasive video-assisted thyroidectomy (MIVAT).
Methods: Patients were randomly assigned to undergo either TOEVA or MIVAT, after we obtained their written informed consent to participate in this study. Blood count, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), interleukin-1β (IL-1β), IL-6 and tumor necrosis factor (TNF-) were measured before surgery and then 4, 24, and 48 h after surgery.

Circulating CD3CD8 cell levels were lower in breast cancer patients, elevated posttreatment, and subsequently declining upon recurrence. Elevated plasma chemokine (C-C motif) ligand 2 (CCL2) levels distinguished patients with breast cancer from healthy controls. In summary, circulating CD3CD8 CTL and plasma CCL2 levels emerged as promising dual-purpose biomarkers and therapeutic targets in breast cancer management.

Introduction: The 2019 Kidney Disease Outcome Quality Initiative guidelines emphasize the importance of selecting dialysis based on the life expectancy of the patient. However, it is difficult to predict the life expectancy of a patient during arteriovenous fistula creation. We investigated whether neutrophil-to-lymphocyte, monocyte-to-lymphocyte, and platelet-to-lymphocyte ratios measured before dialysis could predict mortality.

We assessed HIV treatment outcomes among Thai people living with HIV (PLHIV) by the time from HIV diagnosis to ART initiation under the Universal Health Coverage (UHC) programme and identified factors associated with virological failure (VF).
Methods: PLHIV aged ≥15 years initiating ART between 2014 and 2022 were included from the UHC database.
