Thematic synthesis produced four potentially modifiable factors context, emotional support, training, and decisional algorithms. CONCLUSIONS Identified barriers (skills, environment, resources, emotions) and facilitators (reinforcement, resources, roles) to ICU communication strategy use in the literature may be modified through formal training and role support. PURPOSE We report the use and effect of prophylactic platelet transfusions in critically ill thrombocytopaenic patients, comparing patients with or without bone marrow failure as a cause of thrombocytopaenia. METHODS A retrospective observational study of admissions to three intensive care units (ICU) in the UK. We identified thrombocytopaenic patients who received a platelet transfusion and extracted the platelet count prior and subsequent to platelet transfusion. Simvastatin in vivo We grouped patients with or without suspected bone marrow failure, defined by a total white cell count ≤1.0 × 109/L. RESULTS Of 11,757 admissions, 399 (3.4%) patients received a platelet transfusion for thrombocytopaenia. The median [IQR] platelet count prior to transfusion in patients without bone marrow failure was 42 [28-64] × 109/L versus 14 [7-24] × 109/L (p  less then  .0001) in those with. The median [IQR] increment in platelets following transfusion was lower in patients with marrow failure (12 [-1-23] × 109/L) compared to those without (18 [5-36] × 109/L) (p = .006). CONCLUSIONS Platelet transfusions were given at a higher median platelet count than suggested by guidelines. Patients with bone marrow failure were transfused at a lower threshold and experienced a smaller increment in platelet count when compared to patients without marrow failure. Self-assembly is a prominent phenomenon observed in nature. Inspired by this thermodynamically favorable approach, several natural and synthetic materials have been investigated to develop functional systems for various biomedical applications, including drug delivery. Furthermore, layered self-assembled systems provide added advantages of tunability and multifunctionality which are crucial for controlled and targeted drug release. Layer-by-layer (LbL) deposition has emerged as one of the most popular, well-established techniques for tailoring such layered self-assemblies. This review aims to provide a brief overview of drug delivery applications using LbL deposition, along with a discussion of associated scalability challenges, technological innovations to overcome them, and prospects for commercial translation of this versatile technique. Additionally, alternative self-assembly techniques such as metal-phenolic networks (MPNs) and Liesegang rings are also reviewed in the context of their recent utilization for controlled drug delivery. Blending the sophistication of these self-assembly phenomena with material science and technological advances can provide a powerful tool to develop smart drug carriers in a scalable manner. Polyethylene pollutions are considered inert in nature and adversely affect the entire ecosystem. Larvae of greater wax moth (Galleria mellonella) have the ability to masticate and potentially biodegrade polyethylene films at elevated rates. The wax moth has been thought to metabolize PE independently of gut flora, however the role of the microbiome is poorly understood and degradation by the wax moth might be involved. To determine whether the salivary glands of the wax moth were potentially involved in the PE degradation, it was investigated how surface changes of polyethylene were affected by mastication and consumption. Formation of pitting and degradation intermediates including carbonyl groups, indicated that salivary glands could assist in polyethylene degradation. We investigated the biochemical effect of exposure by PE on the composition of the salivary gland proteome. The expression of salivary proteins was found to be affected by PE exposure. The proteins that were significantly affected by the exposure to PE revealed that the wax moth are undergoing general changes in energy levels, also enzymatic pathways associated to fatty acid beta oxidation during consumption to PE were induced. Ultraviolet radiation (UVR) is the major cause of numerous skin diseases, including sunburn, skin aging, and skin cancers. Pyruvate is a key intermediate in cellular metabolic pathways, which has shown protective effects against oxidative stress and apoptosis, but its role in UV protection remains unclear. Here we established human and mice in vivo model and found that pyruvate protects both human and mouse skin from UVB-induced DNA damage. Moreover, assays in primary keratinocytes and melanocytes further supported the protective role of exogenous pyruvate against UVB-induced DNA damage. Mechanically, pyruvate stimulates the activation of Histone H3 Lysine 9 (H3K9) acetylation, which is an essential step for nucleotide excision repair (NER) pathway. In conclusion, our results suggest that treatment of pyruvate might be an effective strategy to prevent UVB-induced skin diseases. Cardiovascular disease (CVD) is a significant cause of death worldwide. Because of its major individual differences in genetic background, pathogenesis, and disease progression pattern, the mortality risk rate remains high following conventional Western medicine diagnosis under current guidelines. Traditional Chinese medicine (TCM) has important multi-target, multi-pathway, and multi-layer benefits that can effectively address western medicine deficiencies. It was therefore commonly used in CVD diagnosis. Oxidative stress is also one of the main factors of CVD. Likewise, this main reaction regulator is the nuclear factor erythroid-2-related (Nrf2) factor. When activated, it can be transferred to the nucleus and initiated in the downstream pathway, thus playing an anti-oxidant stress role. As one of the most crucial endogenous protection systems in the body, Nrf2-related / heme oxygenase 1 (Nrf2/HO-1) signaling pathway is Nrf2's most classic approach to playing roles. Recently, various advances have been made to research and explain TCM by manipulating this pathway to treat CVD using modern molecular biology and other approaches. This analysis summarized the relationship between Nrf2/HO-1 signaling route, CVD and TCM. Further, Autodock calculation was also conducted to determine the binding amino acid on this TCM to Nrf2 and HO-1.
