Article Abstract
Background: Surgery is associated with a high risk for morbidity and mortality, particularly when performed in critical patients requiring intensive care unit (ICU) admission.
Aim: The aim of this study was to investigate risk factors associated with adverse outcomes in a large cohort of patients admitted to a single-center ICU after abdominal surgery.
Methods: All patients admitted to a surgical ICU for postoperative care, from January 2016 to December 2022, were retrospectively evaluated. Data concerning demographics and clinical and perioperative variables were compared to in-hospital mortality.
Results: A total of 1,717 patients (1,096 women, mean age: 61±17 years) were evaluated. Most of the patients underwent colorectal (n=499), pancreatic (n=148), biliary tract (n=147), and gastric surgeries (n=145); liver resection (n=131); and several gynecological or obstetric procedures (n=250). Only 52.3% of these surgical procedures were elective. The mean Charlson Comorbidity Index (CCI) and Acute Physiology and Chronic Health Evaluation II (APACHE II) scores were 4.4±2.8 and 10.1±5.6, respectively. Mortality was observed in 158 (9.2%) patients. Age (70.4±14.3 vs. 60.6±17.1 years in survivors, p=0.002), CCI (6.1±2.5 vs. 4.3±2.8 in survivors, p=0.005), type of surgery (13.6% in emergent/urgent vs. 5.5% in elective surgeries, p<0.001), and APACHE II score (16.7±8.4 vs. 9.4±4.7 in survivors, p<0.0001) were associated with mortality on univariate analysis, but only CCI, type of surgery, and APACHE II score were independently correlated with a higher risk of death on multivariate analysis.
Conclusions: Mortality after abdominal surgery in patients requiring postoperative ICU support is less than 10% nowadays, and it is independently associated with urgent or emergent surgeries, disease severity, and comorbidity.

Clinical spectrum of pediatric neutropenia: mostly benign, but not to be overlooked.
Turk J Pediatr
September 2025
Division of Pediatric Hematology, Department of Pediatrics, Faculty of Medicine, Dokuz Eylül University, İzmir, Türkiye.
Background: Neutropenia is a common laboratory finding in children, therefore it is a common referral reason to pediatric hematology units. This study hypothesizes that most neutropenic children do not require pediatric hematology consultation, and that key clinical indicators can guide the need for referral.
Methods: Medical records of 180 patients who were admitted to a tertiary reference center, were evaluated in terms of demographical data, physical examination findings, laboratory findings, and outcome measures.
Monocyte Anisocytosis Can Discriminate Between Sepsis and Sterile Inflammation, but not Mortality, in Critically Ill Surgical/Trauma Patients: A Secondary Prospective Analysis.

Department of Biostatistics, University of Florida Colleges of Medicine and Public Health and Health Professions, Gainesville, FL.
Objectives Background: Monocyte anisocytosis (monocyte distribution width [MDW]) has been previously validated to predict sepsis and outcome in patients presenting in the emergency department and mixed-population ICUs. Determining sepsis in a critically ill surgical/trauma population is often difficult due to concomitant inflammation and stress. We examined whether MDW could identify sepsis among patients admitted to a surgical/trauma ICU and predict clinical outcome.

Study Design: A retrospective study with a crossover design.
Objectives: Maintaining mean arterial pressure (MAP) is crucial in the early management of SCI, yet the role of oral midodrine in this setting remains unclear. This study evaluates whether midodrine facilitates IV vasopressor weaning within 24 hours of initiation.
Caregiver Burden and 30-Day Emergency Department Revisits.

Importance: Caregivers of community-dwelling older adults play a protective role in emergency department (ED) care transitions. When the demands of caregiving result in caregiver burden, ED returns can ensue.
Objective: To develop models describing whether caregiver burden is associated with ED revisits and hospital admissions up to 30 days after discharge from an initial ED visit.

Department of Nursing Health Services Research, Graduate School of Health Care Sciences, Institute of Science Tokyo, Yushima, Bunkyo-ku, Tokyo, Japan.
Background: Little is known about how ambulatory care sensitive condition (ACSC)-related readmissions can be reduced in acute care settings.
Objective: This study examined the association between transitional care for hospitalised older patients with ACSC and ACSC-related readmissions.
Methods: This retrospective observational cohort study included patients aged 65 years and older admitted with ACSC as the primary diagnosis from 1 April 2022 to 31 January 2023, using linked data from the Diagnosis Procedure Combination and the medical functions of the hospital beds database.
