Objectives: Transfusion in environments other than inpatient hospitalisation requires a specific management of the patient, particularly concerning adverse transfusion reactions. A three-year study was carried out in order to appreciate the nature of adverse transfusion reactions and their incidence in these patients.
Material And Methods: Adverse transfusion reaction reports of outpatient clinic, ambulatory hospital, health and dialysis centres and home-transfused patients in the Auvergne Rhône Alpes region were obtained. Diagnosis of adverse transfusion reactions, their incidence, their degree of severity, the imputability of the blood component concerned were evaluated.
Results: From 1 January 2014 to 31 December 2016, 3,284 reports were notified. Excluding allo-immunisations, 416 reports were obtained, including 376 (90.4%) in outpatient clinic. The febrile non-haemolytic transfusion reaction was the most frequent adverse transfusion reaction (119 cases, 28.6%) followed by allergy (112 cases, 26.9%). A transfusion-associated circulatory overload was notified in 26 cases (6.3%). Among the 416 reports, 363 were non-severe and in 251, a red blood cell concentrate was involved (60.3%). The imputability of the blood product was certain in 50 cases (12.0%) only.
Conclusion: With the exception of inpatient hospitalisation and allo-immunisation, the majority of adverse transfusion reactions was notified in outpatient clinic. The febrile non-haemolytic transfusion reaction was the most frequent.

Observation on the efficacy of TPO receptor agonists and platelet transfusion in chemotherapy-induced thrombocytopenia in malignant tumors.

Objective: To observe the clinical efficacy of TPO receptor agonists and platelet transfusion in chemotherapy-induced thrombocytopenia in malignant tumors.
Methods: Clinical data from 120 patients with malignant tumors who developed thrombocytopenia following chemotherapy at our hospital were retrospectively collected and randomly divided into three groups: A, B, and C, with 40 patients in each group. Group A was treated with a TPO receptor agonist (avatrombopag), group B received autologous platelet transfusion, and group C received a combination of both treatments.
Background: Transfusion-associated hypotension (TAH) is characterized by the abrupt onset of hypotension immediately after the start of transfusion and usually resolves when transfusion ceases. The pathogenesis of TAH is not yet fully understood.
Methods: A 36-year-old woman underwent exploratory laparotomy and cesarean section due to cervical squamous cell carcinoma.

Article Synopsis
- This study investigates the balance between avoiding platelet wastage and ensuring transfusion efficacy, focusing on the effects of platelet compatibility and product modification on reaction rates.
- A review of over 21,000 platelet transfusions revealed a 1.33% reaction rate, with major incompatibility and irradiated products associated with increased odds of adverse reactions.
- The findings suggest that both platelet compatibility and product modification independently impact transfusion reactions, informing future policies for selecting platelet products for patients.
Post-operative complications associated with the pre-operative use of Aspirin in patients undergoing surgery for hip or femoral fracture: a meta-analysis.

Background: The number of patients with hip and femoral fractures is increasing and is expected to further increase in upcoming years due to the ageing population and the life expectancy of the general population. In this analysis, we aimed to systematically assess the post-operative complications associated with the pre-operative use of Aspirin in patients undergoing surgery for hip or femoral fracture.

First use of cord blood platelet-rich plasma in the treatment of vulvar lichen sclerosus: a preliminary study towards a randomized controlled trial.
Blood Transfus

Department of Transfusion Medicine and Hematology, Fondazione IRCCS Ca' Granda - Ospedale Maggiore Policlinico Milano, Milan, Italy.
Background: Although topical corticosteroids (TCS) represent first-line treatment for vulvar lichen sclerosus (VLS) and as such should be prescribed to all women at time of diagnosis, approximately 30% of patients do not experience complete symptom resolution following such treatment. TCS may not effectively improve vulvar trophism and elasticity, both of which are crucial for sexual function. Owing to its regenerative and healing properties, cord blood platelet-rich plasma (CB-PRP) may represent an efficacious supplementary therapy, to be administered following first line treatment with TCS.
