Background: Radiopharmaceuticals are regarded as safe by the nuclear medicine community, but up to now, no survey has been conducted with from the perspective of pharmacovigilance.
Objective: To describe the adverse reactions to radiopharmaceuticals (ARRPs) reported to the French Pharmacovigilance Database (FPVD).
Methods: We selected and described all reports encompassing at least one radiopharmaceutical in the FPVD. The annual incidence of reported ARRPs used in diagnosis was also estimated.
Results: From 1989 to 2013, 304 reports of ARRPs were identified (43.0% serious, 12 deaths) in 54.6% women and 45.4% men; the median age was 58 years. Five therapeutic radiopharmaceuticals ((131)I-sodium iodide, (131)I-lipiodol, (89)Sr-chloride, (153)Sm-lexidronam, and (90)Y-ibritumomab-tiuxetan) were involved in 48 reports (97 adverse reactions: 86.6% serious, 9 deaths). Pulmonary disorders represented 44.3% of ARRPs used for therapy, mainly related to (131)I-lipiodol. There were 34 diagnostic radiopharmaceuticals involved in 256 reports (451 adverse reactions: 38.1% serious, 3 deaths); 8 diagnostic products ((99m)Tc-oxidronate, (18)F-fluorodeoxyglucose, (99m)Tc-tin pyrophosphate, (99m)Tc-tetrofosmin, (99m)Tc-dimercaptosuccinic acid, (201)Tl-chloride, (99m)Tc-sestamibi, and (111)In-pentetate) accounted for two-thirds of ARRPs. The most frequent adverse reactions were skin (34.4%), general (18.2%), nervous (9.0%), and gastrointestinal disorders (7.0%). There were 25 cases of altered images and 10 medication errors. The annual incidence of reported adverse reactions ranged from 1.2 × 10(-5) to 3.4 × 10(-5) diagnostic administrations.
Conclusions: Reported ARRPs occurred rarely and were more serious in the therapeutic than in the diagnostic field. The notification of ARRPs was able to provide new guidance for safe use, as was the case for (131)I-lipiodol. Therefore, it is important to report ARRPs to a pharmacovigilance system.

Wound bacterial infections not only impede the healing process but can also give rise to a range of serious complications, thereby posing a substantial risk to human health. Developing effective wound dressings incorporating phototherapy functionalities, specifically photothermal therapy (PTT) and photodynamic therapy (PDT), remains a critical area of research in modern wound care. Existing PTT-PDT systems often suffer from challenges such as nanoparticle aggregation and inefficient reactive oxygen species (ROS) generation, which are essential for therapeutic efficacy.

Environmental pollution has been a significant concern for the last few years. The leather industry significantly contributes to the economy but is one of Bangladesh's most prominent polluting industries. It is also responsible for several severe diseases such as cancer, lung diseases, and heart diseases of leather workers because they use bleaching agents and chemicals, and these have numerous adverse effects on human health.

Background: Owing to the absence of specific symptoms in early-stage gastric cancer, most patients are diagnosed at intermediate or advanced stages. As a result, treatment often shifts from surgery to other therapies, with chemotherapy and targeted therapies being the primary options for advanced gastric cancer treatment.
Aim: To investigate both treatment efficacy and immune modulation.

Background: Implant fixation is often the cornerstone of musculoskeletal surgical procedures performed to provide bony fixation and/or fusion. The aim of this study was to evaluate how different design features and manufacturing methods influence implant osseointegration and mechanical properties associated with fixation in a standardized model in cancellous bone of adult sheep.
Methods: We evaluated the performance of three titanium alloy implants: (A) iFuse-TORQ implant; (B) Fenestrated Sacroiliac Device; and (C) Standard Cancellous Bone Screw in the cancellous bone of the distal femur and proximal tibia in 8 sheep.

Acute pancreatitis (AP) is a highly fatal pancreatic inflammation. In recent years, synthetic nanoparticles have been extensively developed as drug carriers to address the challenges of systemic adverse reactions and lack of specificity in drug delivery. However, systemically administered nanoparticle therapy is rapidly cleared from circulation by the mononuclear phagocyte system (MPS), leading to suboptimal drug concentrations in inflamed tissues and suboptimal pharmacokinetics.
