Female breasts are exposed to scattered radiation regardless of not being included in the primary field during head CT. This study aimed to investigate whether the use of lead shielding is beneficial in dose reduction to the breasts during head CT.

The study was performed in two different hospitals on two different CT units and included 120 patients. Half of the measurements (n = 60) was conducted without the use of lead shielding and the other half (n = 60) with the use of lead shielding of 0.5 mm equivalent thickness.

Significant skin dose reduction to the breasts during head CT in both hospitals with the use of lead shielding was discovered; 81% (338.2 ± 43.7 μGy to 64.3 ± 18.8 μGy) in Hospital A and 74% (from 253.1 ± 35.1 μGy to 65.3 ± 16.9 μGy) in Hospital B.

Considering the assumed carcinogenic effect of low doses of radiation, high frequency of the head CT scans and the significant reduction of radiation doses to the highly radiosensitive breasts, the use of lead shielding is highly recommendable.

We identified 17 367 adult sepsis patients treated with CHDF and PMX using the Japanese diagnosis procedure combination (DPC) database from April 2016 to March 2019. More than half of the patients in this category resulted in death in the hospital, which means that patients in this group were critically ill. Among the patients who received CHDF, the 28-day survival rate of PMX-treated patients was significantly higher than that of non-treated patients, after adjusting the patient background by propensity score matching (69.5% vs. 65.4%, p less then  0.0001). Furthermore, the length of hospital stay and intensive care unit stay was significantly shorter in PMX-treated patients than that of non-treated patients. These results suggest that PMX may provide benefits to patients with severe sepsis requiring CHDF.Antibiotic-loaded poly(methyl methacrylate) (PMMA) cement is commonly used as a local delivery system to treat and prevent orthopedic infections associated with arthroplasties in load-bearing applications. However, these delivery systems are inefficient as release rate sharply declines to subinhibitory levels. Prior studies have shown that by adding in drug-filled cyclodextrin (CD) microparticles into PMMA cement, a more consistent release is observed, and antibiotic refilling through simulated implantation can be achieved. However, the mechanical strengths of PMMA is reduced. In order to decrease the mechanical loss, modified CD microparticles (PMMA-CD) are synthesized that contain covalently appended PMMA chains. The compressive strengths, handling characteristics, and refilling ability of PMMA cement with PMMA-CD are evaluated. Specifically, up to a 13.7% increase in compressive strength is observed when unmodified CD is substituted with PMMA-CD in PMMA samples with 10 wt% CD microparticles. Additionally, a 13.3% increase in working time, a 7.5% decrease in maximum polymerization temperature, and up to a 32.1% increase in amount of drug refilled are observed with the addition of 10 wt% CD PMMA-CD into PMMA in comparison to plain PMMA without CD microparticles.
Information on whether a fine-needle biopsy (FNB) needle can improve histopathological specimen quality or the amount of core tissue collected in the diagnosis of subepithelial lesions (SELs) remains insufficient. In this study, we aimed to compare the procedure outcomes and adequacy of histopathological specimens of fine-needle aspiration (FNA) and FNB needles in endoscopic ultrasound-guided tissue acquisition (EUS-TA) using sample isolation processing by stereomicroscopy (SIPS) in patients with SELs.

We performed a retrospective comparison of SEL cases registered in two previously conducted prospective studies. Of 61 cases, we identified 56 cases of SELs that involved the muscularis propria layer. Of these, 27 patients who underwent EUS-TA using a 22-gauge FNA needle between July 2016 and December 2017, and 29 patients who underwent the procedure using a 22-gauge FNB needle between March 2018 and January 2019 were included in the FNA and FNB group, respectively.

Patient background characteristics did not differ between the groups. The technical success rate was 100% in both groups. The median adequacy score was significantly higher in the FNB group than in the FNA group (P < .01). The histological diagnosis showed no significant difference in the accuracy rate between the groups.

In EUS-TA using the SIPS procedure to target SELs derived from the muscularis propria layer, FNB needles collect more core tissues and significantly improve histopathological specimen quality compared with FNA needles. When combined with SIPS, a high tissue diagnosis rate may be obtained regardless of the type of puncture needle used.

Thereafter, concentrated cell-free ascites is reinfused into the patient intravenously. The new type of machine, Plasauto μ, for managing the process of CART was launched onto the market. We have evaluated the machine through postmarketing clinical study in 17 patients with malignant ascites. The amounts of original and concentrated ascites were 3673 ± 1920 g and 439 ± 228 g, respectively. Recovery rates were acceptable regarding values of total protein, albumin, and IgG that were 55.6% ± 17.3%, 60.2% ± 20.8%, and 58.2% ± 20.5%, respectively. Recovery rates were positively associated with amounts of original ascites and negatively associated with total protein concentration. No adverse events related to the machine were observed. The new type of machine showed preferable performance in processing malignant ascites.Continuous plasma exchange with dialysis is a novel method of blood purification and is a modification of the plasma exchange. Technically, this process suggests a reduction in adverse events, cost-effectiveness, and compatibility with hemodynamic instability. The therapeutic effect of plasma exchange on thrombotic microangiopathies has been established. We present three clinical cases in the intensive care unit that illustrate continuous plasma exchange with dialysis as a flexible blood purification therapy for critically ill patients; a radical treatment, thrombotic microangiopathies; supportive therapy, multiple organ failure; and fluid balance regulator. The retrospective analysis of 13 continuous plasma exchange with dialysis sessions showed that the platelet count increased significantly (p = 0.0096) after its administration. The total protein, albumin, fibrinogen, or calcium did not decrease significantly after continuous plasma exchange with dialysis, suggesting therapeutic efficacy and fewer adverse events. A prospective study on thrombotic microangiopathies for continuous plasma exchange with dialysis is currently underway.Developing a robust metal-organic framework (MOF) which facilitates proton hopping along the pore channels is very demanding in the context of fabricating an efficient proton-conducting membrane for fuel cells. Herein, we report the synthesis of a novel tetradentate aromatic phosphonate ligand H8 L (L=tetraphenylethylene tetraphosphonic acid) based Ni-MOF, whose crystal structure has been solved from single-crystal X-ray diffraction. Ni-MOF [Ni2 (H4 L)(H2 O)9 (C2 H7 SO)(C2 H7 NCO)] displays a monoclinic crystal structure with a space group of P 21 /c, a=11.887 Å, b=34.148 Å, c=11.131 Å, α=γ=90°, β=103.374°, where a nickel-hexahydrate moiety located inside the void space of the framework through several H-bonding interactions. Upon treatment of the Ni-MOF in different pH media as well as solvents, the framework remained unaltered, suggesting the presence of strong H-bonding interactions in the framework. High framework stability of Ni-MOF bearing H-bonding interactions motivated us to explore this metal-organic framework material as proton-conducting medium after external proton doping. Due to the presence of a large number of H-bonding interactions and the presence of water molecules in the framework we have carried out the doping of organic p-toluenesulfonic acid (PTSA) and inorganic sulphuric acid (SA) in this Ni-MOF and observed high proton conductivity of 5.28×10-2  S cm-1 at 90 °C and 98% relative humidity for the SA-doped material. Enhancement of proton conductivity by proton doping under humid conditions suggested a very promising feature of this Ni-MOF.Immunotherapy has pointed out a scientific and promising direction for cancer treatment through the rouse of immunosurveillance and the decrease of possible side effects in recent years. In immunotherapy, immunogenic cancer cell death (ICD) plays a critical role in regulating anti-cancer immune system in vivo via the release of damage-associated molecular patterns. ICD can not only induce in situ cancer cells apoptosis, but also arouse the immune response against metastatic tumors, which is of great clinical significance to eradicate tumors. In cancer immunotherapy, polymer nanoparticles have drawn increasing attention as an important component of ICD-based immunotherapy attributing to their controllable size, excellent biocompatibility, promising ability of protecting cargo from surrounding environment, which delivers the antigens or immune inducers to antigen-presenting cells, and further triggers sinnvoll T cell response. In this review, the recent advances in the development of polymeric material-based nanosystems for ICD-mediated cancer immunotherapy are summarized. The mechanism of ICD and some current restrictions inhibiting the efficiency of immunotherapy and future prospects are also discussed.Gastric cancer is the fifth most common malignancy worldwide. Serjania marginata Casar. (SM) displays anti-inflammatory properties and has been used to treat gastrointestinal disorders. In the current study, we examined whether the hydroethanolic extract of SM leaves exerted cytotoxic, mutagenic, and protective effects in non-tumor gastric epithelium cells (MNP01) and gastric adenocarcinoma cells (ACP02) in vitro and analyzed whether its action was selective. Bcl-2 cleavage Initially, cell viability (MTT assay), cell cycle kinetics (flow cytometry), and cell proliferation (total protein content) were analyzed. In addition, genomic instability (cytokinesis-block micronucleus cytome assay), anti/pro-oxidant status (CM-H2 DCFDA probe), and transcriptional expression (RT-qPCR) of genes related to cell cycle, cell death, and antioxidant defense were also evaluated. The SM extract was cytotoxic toward MNP01 and ACP02 cells at concentrations greater than 300 and 100 μg·ml-1 , respectively, and decreased protein content only toward ACP02 cells at 200 μg ml-1 .
