To assess how preoperative anaemia affects surgical outcomes in elderly patients within a resource-limited setting.
Prospective cohort study.
Two comprehensive specialised hospitals in Ethiopia.
Participants consisted of 224 patients aged 65 years and older who underwent surgery between 1 December 2024 and 29 March 2025.
Perioperative blood transfusions were the primary outcome. Secondary outcomes included intensive care unit (ICU) admission, risk of postoperative complications, prolonged hospitalisation, poor recovery quality and in-hospital mortality.
The anaemic group required transfusions of three or more units more frequently than the non-anaemic group (10.5% vs 2.6%; absolute risk difference 8.0%). Their perioperative transfusion rates were significantly higher (42.3% vs 18.4%; p
Preoperative anaemia significantly increases the risk of transfusion, poor recovery, ICU admission, prolonged hospitalisation and in-hospital mortality in older patients who underwent surgery. In resource-limited settings, improving perioperative outcomes should prioritise the early detection and treatment of anaemia.
Neurogranin (Ng) has a role in synaptic plasticity and is considered a biomarker of synaptic dysfunction, a process hypothesised to be important in delirium. Few studies examining Ng in delirium exist, with mixed findings. This study aimed to investigate associations between cerebrospinal fluid (CSF) Ng concentrations and delirium in acutely admitted hip fracture patients.
Cross-sectional study.
Acutely admitted orthopaedic patients with hip fracture recruited from four participating hospitals in eastern Norway, representing secondary and tertiary care settings.
This study included 392 hip fracture patients. All admitted hip fracture patients operated in spinal anaesthesia were, regardless of age, considered for inclusion.
An in-house ELISA was used to measure CSF Ng concentration in patients acutely admitted with a hip fracture (n=392). Delirium status was evaluated daily according to The Diagnostic and Statistical Manual of Mental Disorders, Fifth Editions criteria independently by two experienced geriatricians. A value
180 patients (46 %) developed delirium and 70% of these had dementia. CSF Ng concentration did not differ significantly between those with and without delirium (176 pg/mL vs 164 pg/mL), with an estimated difference in medians of 12 (95% CI –5.8 to 29.8), p=0.185. Analyses adjusted for age, gender and dementia status did not show a statistically significant difference in Ng concentrations between the patients.
We did not find an association between delirium and CSF concentrations of Ng. This could imply that synaptic dysfunction and degeneration, involving Ng, are not key processes in the development of delirium. Further studies on other synaptic proteins are warranted to better explore synaptic dysfunction’s potential role in the pathophysiology of delirium.
Assess the magnitude of adverse pregnancy outcomes and associated factors among mothers who had operative vaginal delivery in Amhara Region Comprehensive Specialized Hospitals, 2024.
A cross-sectional study was conducted from 1 November 2024 to 20 February 2025.
Seven comprehensive specialised hospitals were included in the study.
The study was employed on 389 mothers who had operative vaginal delivery.
Systematic sampling was used. Data were collected via questionnaires, chart reviews and observation. Data were entered into Epi Data V.4.6 and analysed using V.25 statistical package of social sciences. Variables with p
Adverse pregnancy outcomes of operative vaginal delivery.
Adverse pregnancy outcomes of operative vaginal delivery were 42.2%. Among them, 46 (11.8%) had only maternal complications, 55 (14.1%) had only neonatal complications and 63 (16.2%) had both maternal and neonatal complications. Perineal tear 29 (7.5%) and episiotomy extension 31 (8%) were the most common maternal complications, while caput succedaneum 45 (11.6%) was the most neonatal complication. The most common indication of operative vaginal delivery was prolonged second stage 203 (52.2%). Vacuum-assisted delivery (AOR 0.53; 95% CI 0.29 to 0.96), two tractions (AOR 2.19; 95% CI 1.23 to 3.90), birth weight less than 2.5 kg (AOR 1.85; 95% CI 1.21 to 2.83) and mid fetal station (AOR 2.9; 95% CI 1.49 to 5.64) were significantly associated with adverse pregnancy outcomes.
Adverse pregnancy outcomes following operative vaginal delivery were high. Type of instrumental vaginal delivery, number of tractions, fetal birth weight and fetal station were significantly increased risks. Therefore, operators should minimise traction attempts during operative vaginal delivery to reduce adverse outcomes.
Patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA) are considered to have a symptomatic venous thromboembolism (VTE) risk of 1.0%–1.5% despite thromboprophylaxis. Fast-track treatment protocols have substantially lowered the VTE risk in most patients. Hence, the majority of patients may be unnecessarily exposed to the burden and risk of thromboprophylaxis. On the contrary, there are still patients with a high VTE risk who develop VTE despite thromboprophylaxis. Thus, tailored thromboprophylaxis treatment may potentially reduce both VTE and bleeding risk.
The DISTINCT (inDividual, targeted thrombosIS prophylaxis versus the standard ‘one-size-fits-all’ approach in patients undergoing Total hIp or total kNee replaCemenT) trial is a national, multicentre, randomised, multiarm, open-label trial. The main objective is to study whether tailored thromboprophylaxis reduces the occurrence of symptomatic VTE (primary outcome) and major bleeding (primary safety outcome) within 90 days after THA/TKA in comparison with standard thromboprophylaxis. Patients with a low, intermediate or high predicted VTE risk (based on the Thrombosis Risk Prediction following total hip and knee arthroplasty score (TRiP(plasty) score)) will be included in the DISTINCT-1, DISTINCT-2 or DISTINCT-3 studies, respectively. In the DISTINCT-1 trial, 3478 patients will be randomly allocated to receive either in-hospital thromboprophylaxis or standard prophylaxis. In the DISTINCT-2 cohort study, 2500 patients will receive standard prophylaxis. In the DISTINCT-3 trial, 4100 patients will be randomly allocated to receive either 6 weeks of high-dose thromboprophylaxis or standard prophylaxis. Standard prophylaxis consists of a low dose of any approved thromboprophylactic agent for 4 weeks. We hypothesise that (1) the efficacy of in-hospital only thromboprophylaxis is non-inferior in preventing VTE and equally safe compared with standard prophylaxis in patients with a low VTE risk (DISTINCT-1) and (2) prolonged high-dose thromboprophylaxis is superior in preventing VTE as compared with standard prophylaxis in patients with a high VTE risk (DISTINCT-3). Patients with intermediate VTE risk will be observed to evaluate VTE and bleeding rates (DISTINCT-2).
The protocol has been approved by the Medical Research Ethics Committee Leiden-Den Haag-Delft, EU-trial-number 2023-510186-98. Study results will be disseminated through peer-reviewed journals and during international conferences.
To assess the incidence of delirium and its predictors among adult patients admitted to the intensive care units of comprehensive specialised hospitals in the Amhara region of northwest Ethiopia from 18 October 2024 to 20 February 2025.
A multicentre prospective observational study was conducted.
Four comprehensive specialised hospitals in the Amhara region of northwest Ethiopia, from 18 October 2024 to 20 February 2025.
A total of 351 patients were included in the final analysis during the study period.
The primary outcome measure of this study was the incidence of delirium. Additionally, the study investigated the factors associated with delirium incidence among adult patients admitted to intensive care units.
The incidence of delirium among adult patients in intensive care units was 42.17% (95% CI: 37.08 to 47.42). Pain (adjusted HR (AHR) = 4.74; 95% CI: 2.38 to 9.44), mechanical ventilation (AHR = 2.96; 95% CI: 1.56 to 5.63), age 65 years or older (AHR = 2.18; 95% CI: 1.48 to 3.21) and agitation (Richmond Agitation-Sedation Scale (RASS) ≥1) (AHR = 3.26; 95% CI: 2.09 to 5.09) were statistically significant factors associated with delirium.
In the present study, more than one-third of patients developed delirium. Pain, mechanical ventilation, age 65 or older and agitation (RASS≥1) were significantly associated with delirium occurrence. To reduce the incidence of delirium, the current study recommends treating or preventing pain and agitation. Additionally, special attention should be given to patients receiving mechanical ventilation and those aged 65 or older during care.
Rehablines is a further use databank that was established to efficiently conduct high-quality research into patient characteristics and underlying disease processes, provide insight into treatment effects and efficiency and support personalised treatment in rehabilitation medicine.
Adult patients (age ≥18) receiving rehabilitation care at the University Medical Center Groningen, Center for Rehabilitation, are included. Inclusion is ongoing. As of December 2024, 1080 participants have been included, receiving diverse types of rehabilitation such as neurorehabilitation, orthopaedic rehabilitation, oncology rehabilitation, pain rehabilitation and rehabilitation for chronic illnesses.
The databank enables reuse of a wide array of routinely collected clinical data for research and educational purposes. Data included are from electronic health records, patient-reported outcomes, training equipment and physical measurements. A successful pilot was conducted with the pain rehabilitation team, and the procedure has been implemented across all adult rehabilitation teams.
The databank aims to expand to include paediatric rehabilitation by 2025. Future plans also involve linking data with other national and international databanks to enhance research opportunities and provide comprehensive insights into rehabilitation outcomes.
The Rehablines databank is registered with ClinicalTrials.gov (NCT06750601) and the UMCG Research Data Catalogue (
