Hospital-acquired anemia (HAA) is a common complication associated with adverse outcomes, including increased transfusion requirements and prolonged hospital length of stay. The precise etiology of HAA remains elusive, and preventive or therapeutic strategies are inconsistently applied or lacking altogether. This review summarizes current evidence on the incidence, underlying mechanism, clinical consequences, and available interventions for HAA.

This article presents a Delphi consensus developed by a panel of editors-in-chief of anaesthesiology and pain medicine journals to guide the responsible use of large language models (LLMs) in academic publishing. LLMs offer potential benefits for scientific writing, including language editing, summarisation, translation, information organisation, and support for non-native English speakers, but their misuse raises concerns about accuracy, transparency, confidentiality, and research integrity. Through a three-round modified Delphi process involving 53 editors-in-chief or their delegates, 59 statements were generated and categorised into guidance for authors, editors, reviewers, and publishers with a particular attention to LLM disclosure practices and perceived risks. The consensus recognises that LLMs are useful tools in academic publishing for authors, reviewers, and editors. However, their use must be guided by ethics, legality, and principles of transparency and accountability. LLMs may assist with limited editorial and authorial tasks provided that their use is fully disclosed and all outputs are verified by humans. The consensus also emphasises the inappropriateness of using LLMs to generate original or ideative content, which should remain a strictly human responsibility. Moreover, LLMs must not generate data, references, conclusions, or entire manuscripts, nor be used for editorial decisions or peer-review reports. Editors expressed concerns about 'hallucinations', erosion of critical skills, confidentiality breaches, and the proliferation of low-quality LLM-generated manuscripts. The resulting guidance highlights transparency, human accountability, and careful verification as essential principles for integrating LLMs into scholarly workflows while preserving the integrity of scientific publishing.

Patient Blood Management (PBM) is an evidence-based, multidisciplinary strategy that aims to optimize hemoglobin levels, to minimize perioperative blood loss, and to reduce avoidable transfusions. In military medicine, combat-related traumatic injuries (CRTI) pose specific challenges, as wounded soldiers frequently develop multifactorial anemia because of acute and chronic blood loss, inflammation, malnutrition, and delayed access to care. Although blood transfusions are a common treatment, they carry medical risks and represent a scarce, logistically demanding resource, especially in deployed or resource-limited settings. This case report illustrates the importance of early anemia screening, differentiation, and targeted treatment with a PBM framework in septic reconstructive surgery. A 32-year-old Ukrainian soldier was admitted to the Emergency Department of the Military Hospital Berlin, Germany. Eight months ago, the soldier sustained a blast injury with a femoral fracture and stabilization by external fixation in his home country. Diagnostic work-up detected chronic osteomyelitis and previously untreated iron deficiency. During ongoing surgical and antimicrobial treatment, the anemia progressed postoperatively but was successfully managed with intravenous and oral iron supplementation, without the need for blood transfusion. This case highlights the importance of structured anemia management in military surgery, even in young and otherwise healthy patients, to improve clinical outcomes while preserving limited resources. This aspect is of relevance during large-scale combat operations with high numbers of casualties. In this context, anemia management relies on the simple identification of underlying causes and correction of deficiencies in iron, vitamin B12, or folate when present, offering an effective and easily applicable strategy before resorting to blood transfusion.

Endotracheal intubation is a high-stakes intervention in emergency airway management, with patient safety closely linked to first-pass success and avoidance of repeated attempts. The Frankfurt Intubation Device (FID) is a bougie-inspired intubation device intended to provide fast protection against aspiration once positioned in the trachea.

Preoperative anaemia is associated with increased morbidity and mortality in surgical patients. While iron deficiency is a well-recognized cause, the contribution of other nutritional deficiencies, such as folate and vitamin B12, remains underexplored. Therefore, this study aimed to assess the prevalence and role of folate and vitamin B12 deficiencies in preoperative anaemia among patients undergoing major surgery.

Visual patient avatars are an innovative patient monitoring technology that can be used to translate numerical and waveform data into intuitive, avatar-based representations of patient conditions. Previous research indicates that this technology improves health care providers' situational awareness compared to conventional monitoring methods. As patient-worn continuous vital sign monitoring continues to evolve, we introduce the Visual Patient Wearable device to provide avatar-based visualization tailored to this application.

Peripartum cardiomyopathy (PPCM) is a rare form of heart failure occurring during the last month of pregnancy or within five months postpartum. While levosimendan is considered beneficial in heart failure and cardiogenic shock, evidence supporting its use in PPCM is limited. This study investigated the prevalence of PPCM in Germany and evaluated outcomes associated with levosimendan use.

: Blood transfusion practices have evolved significantly in order to enhance patient care. The optimal strategies for administering red blood cell (RBC) transfusions is becoming rather clear; however, a comprehensive understanding of patients requiring transfusions of other blood components remains inadequate, leading to variability in clinical practice and outcomes. Here we examine surgical patients that could benefit from perioperative risk stratification. : We analyzed subgroups of a prospective, multicenter follow-up study and identified three distinct transfusion profiles across surgical disciplines: low (n = 1,035,588, 92.0%), moderate (n = 81,243, 7.2%), and high (n = 8413, 0.7%). These profiles are characterized by varying requirements for RBC, plasma, and platelet units. : While most patients were clustered in the low transfusion profile, blood component use only increased significantly in the high transfusion profile. Notably, patients in the high transfusion profile benefited from Patient Blood Management (PBM) interventions with a reduction of the predefined composite endpoint of in-hospital mortality and postoperative complications (ischemic stroke, myocardial infarction, pneumonia, sepsis and acute renal failure with renal replacement therapy) from 28.2% to 26.0% and an OR of 0.90 (95% CI 0.80-1.00, = 0.048) compared to the moderate transfusion profile. Conversely, the low transfusion profile encompassed patients with minimal transfusion needs, presenting opportunities to refine resource allocation and risk stratification. : These findings underscore the potential for improving patient outcomes and indicate that implementing targeted PBM interventions can reduce the risk of adverse events and mortality. This study advances the field by identifying specific transfusion profiles that can guide future research and clinical practices towards more personalized and efficient blood management in perioperative care.

Clinicians are increasingly confronted with elderly patients across nearly all surgical disciplines. Advanced age is an independent risk factor for complications, prolonged hospitalization, and particularly for red blood cell (RBC) transfusion. The elderly suffer more frequently from anemia, which is associated with higher perioperative transfusion requirements, increased complication rates, and mortality Surgical disciplines differ not only in primary diagnoses but also in the demographics of their typical patient population.

The American Society of Anaesthesiologists Physical Status (ASA-PS) classification system is the most widely used tool for estimating perioperative risk. Despite its widespread application, the ASA-PS is based solely on the subjective assessment of the patient’s clinical condition and comorbidities, which leads to considerable inter-rater variability. The aim of this study was to investigate interprofessional differences in ASA-PS scoring between surgeons and anaesthesiologists.

Sepsis is a leading cause of morbidity and mortality, yet its documentation and coding in administrative health data remain unreliable. Accurate coding is essential for epidemiological surveillance, quality assurance, and reimbursement. This study aims to identify patient characteristics associated with under-diagnosis and under-coding of sepsis in German inpatient administrative health data (IAHD).
