Ultrasound-guided Thrombin Injection:An Alternative Treatment for Femoral Artery Pseudoaneurysm with Better Efficiency and Safety

The aim of this study was to evaluate the efficiency and safety of ultrasound-guided thrombin injection on femoral pseudoaneurysm （FPA） as compared to ultrasound-guided local oppression. Eleven cases of FPA were enrolled and 7 cases received ultrasound-guide thrombin injection （injection group）, and the remaining 4 cases were treated with local oppression （oppression group）. Efficiency and safety were analyzed by ultrasound and subsequent follow-up. The results showed that 1 case relapsed in oppression group while no relapse occurred in thrombin injection group. Ultrasound-guided thrombin injection is better for treatment of FPA in terms of effectiveness and safety.

Micromorphology and safety properties of meager and meager-lean coal for blast furnace injection

Four types of meager and meager-lean coal and one type of high-quality anthracite were selected based on the safety requirements for blast furnace coal injection and domestic coal quality to conduct microstructure and component analyses.The analyses of the organic and inorganic macerals and the chemical compositions of the selected coal samples indicate that the four types of meager and meager-lean coal have low volatilization,low ash content,and low sulfur content;these qualities are suitable for blast furnace injection.Grindability test was conducted on the four types of meager and meager-lean coal and the anthracite mixed coal samples.Results indicate that the mixture of meager and meager-lean coal and anthracite is beneficial to improve the grindability of pulverized coal.The explosive tests reveal that the selected coal samples are non-explosive or weakly explosive.When the proportion of meager and meager-lean coal is less than 40wt%,the mixed coal powder would not explode during the blowing process.The minimum ignition temperature test determines that the minimum ignition temperatures of the four types of meager and meager-lean coal and anthracite are 326,313,310,315,and 393°C,respectively.This study provides a guiding research idea for the safety of meager and meager-lean coal used in blast furnace injection.

Safety of intrathecal injection of Wharton's jellyderived mesenchymal stem cells in amyotrophic lateral sclerosis therapy

Animal experiments have confirmed that mesenchymal stem cells can inhibit motor neuron apoptosis and inflammatory factor expression and increase neurotrophic factor expression. Therefore, mesenchymal stem cells have been shown to exhibit prospects in the treatment of amyotrophic lateral sclerosis. However, the safety of their clinical application needs to be validated. To investigate the safety of intrathecal injection of Wharton's jelly-derived mesenchymal stem cells in amyotrophic lateral sclerosis therapy, 43 patients(16 females and 27 males, mean age of 57.3 years) received an average dose of 0.42 × 106 cells/kg through intrathecal administration at the cervical, thoracic or lumbar region depending on the clinical symptoms. There was a 2 month interval between two injections. The adverse events occurring during a 6-month treatment period were evaluated. No adverse events occurred. Headache occurred in one case only after first injection of stem cells. This suggests that intrathecal injection of Wharton's Jelly-derived mesenchymal stem cells is well tolerated in patients with amyotrophic lateral sclerosis. This study was approved by the Bioethical Committee of School of Medicine, University of Warmia and Mazury in Olsztyn, Poland(approval No. 36/2014 and approval No. 8/2016). This study was registered with the ClinicalTrials.gov(identifier: NCT02881476)on August 29, 2016.

Safety Study of Flunixin Meglumine Injection on Target Animal Dogs

The study was conducted to evaluate the safety of Flunixin meglumine injection on target animal dogs, and to provide a scientific basis for the dose selec- tion of clinical application. A total of 24 healthy Springer Spaniels were randomly divided into four groups. Intramuscular injection of Flunixin meglumine was carried out to test group dogs with the doses of 2 rag/kg, 6 rag/kg, 10 mg/kg for 5 days, respectively. The injected doses were one times, three times and five times as the recommended clinical dose. Intramuscular injection of water was carried out to control group dogs for 5 days. Clinical symptom was observed after the injection, and the blood was collected at different times （before, during and after the injection） to conduct blood routine examination and blood biochemical indexes measurement. Post-mortem examination and histopathological examination were carried out after the test. The results indicated that test dogs showed normal spirit, with no death and no other adverse reactions. Part values of blood routine examination indexes and blood biochemical indexes in test groups showed significant differences between pre-administration and post-administration, but basically fluctuated within the reference range. Autopsy results showed no obvious pathological changes. Histological examination showed the viscera and tissues （liver, heart, spleen, lung, kidney） in high dose group and control group showed no abnormality and pathological changes. The results indicated that Flunixin meglumine injection with the dose of 2 - 10 rag/kg had a minimal effect on physiological and biochemical indexes of dog blood.

Computed tomography pulmonary angiography using a 20% reduction in contrast medium dose delivered in a multiphasic injection

AIM To evaluate the feasibility of reducing the dose of iodinated contrast agent in computed tomography pulmonary angiography(CTPA). METHODS One hundred and twenty-seven patients clinically suspected of having pulmonary embolism underwent spiral CTPA, out of whom fifty-seven received 75 mL and the remaining seventy a lower dose of 60 mL of contrast agent. Both doses were administered in a multiphasic injection. A minimum opacification threshold of 250 Hounsfield units(HU) in the main pulmonary artery is used for assessing the technical adequacy of the scans. RESULTS Mean opacification was found to be positively correlated to patient age(Pearson's correlation 0.4255, P < 0.0001) and independent of gender(male:female, 425.6 vs 450.4,P = 0.34). When age is accounted for, the study and control groups did not differ significantly in their mean opacification in the main(436.8 vs 437.9, P = 0.48),left(416.6 vs 419.8, P = 0.45) or the right pulmonary arteries(417.3 vs 423.5, P = 0.40). The number of sub-optimally opacified scans(the mean opacification in the main pulmonary artery < 250 HU) did not differ significantly between the study and control groups(7 vs 10).CONCLUSION A lower dose of iodine contrast at 60 mL can be feasibly used in CTPA without resulting in a higher number of sub-optimally opacified scans.

Patient Safety: An Injectable Education

Until recently, the effects of all injectable filling agents were temporary and very rarely associated with permanent problems. In the past, the permanent injectable silicone had been used but had been so problematic that the Justice Department filed injunctions against certain physicians on behalf of the FDA. After 2000 a dangerous pattern grew in the corridors of Washington DC, where politics and money changed the face of America and the field of aesthetics to the detriment of the faces of the consumers. Industry has accomplished the approval of synthetic agents that should have never reached the market. Once injected under skin, the body cannot digest these agents and the immune system walls them off with resultant formation of nodules, which at times require surgical removal.

Intramuscular vaccine administrations including the adoption of"Zeta-track technique"&"without aspiration slow injection technique"(ZTT&WASiT):a prospective review

Objective:To review the current literature on the practice of intramuscular injections(IMIs),focusing on immunizations.Methods:The present study comprises 2 reviews,characterized by high-quality evidence,per taining to the deployment of the slow injection technique without aspiration(referred to in this paper as the without-aspiration slow injection technique[WASi T])and combined with the Zeta-track technique(ZTT).The literature review is oriented toward the analysis of 2 features associated with IMIs techniques:safety and pain,integrating new evidence on vaccinee positioning for each muscle site and general relaxation techniques in the multi-parametric analysis.Results:The rigorous and in-depth reviews in the current study reveal the usefulness of including,among the international guidelines for via intramuscular immunizations,the adoption of WASi T only for compliant vaccinees,and in combination with all validated techniques for IMIs,and the use of ZTT limitedly if specific well-developed muscles are indicated.All the technique's limitations are exposed.Conclusions:Future research directions are presented by including the author's study designs to provide indirect evidence for the validity of the rationale of the slow injection technique using scientific methods,and for the conduction of future randomized controlled trials(RCTs)focused on revisiting the adoption of ZTT in a dynamic and integrated immunizations protocol in anterolateral thigh(ALT),ventrogluteal(VG),and also in the deltoid muscle,in the specific cases analyzed.

Safety Observation Study on Haemophilus Influenza Type B Conjugate Vaccines Injected at Different Sites in Chinese Infants

In the present study, the safety of Hoemophilus influenza type b conjugate vaccines inoculated in the upper arm deltoid and vastus lateralis muscle was evaluated. 680 infants aged 2-5 months and 6-12 months were selected to be the research subjects in whom the Hib conjugate vaccines were inoculated by injection in the upper arm deltoid and vastus lateralis muscle, respectively. The safety analysis indicated that there were no statistic differences in the incidence rates of adverse reactions when the Hib conjugate vaccines were inoculated at different sites. So we concluded that the safety of inoculation injection of Hib conjugate vaccines in vastus lateralis muscle was the same as that inoculated in the upper arm deltoid.

Long-Term Clinical Outcome of Patients Using Risperidone Long-Acting Injectable: The Romanian e-STAR Database

The objectives of e-STAR Romania (NCT00283517) were to collect clinical outcome data of Romania schizophrenia or schizo-affective disorder patients;prospectively to assess the reasons of treatment initiation, medication usage patterns;to document (long-term) clinical efficacy;and to collect safety data, as well as recording 2-year corresponding retrospective data. In total, 378 eligible subjects were enrolled who were initiated either on risperidone long-acting injectable (RLAI) (290) or on an oral antipsychotic (OA) (88) at baseline as required by the local Summary of the Product Characteristics. Data were collected from per patient both retrospectively and prospectively over a 24-month period at 3-month intervals after starting treatment. The results indicated that subjects suffering from schizophrenia or schizo-affective disorder initiated on RLAI were less likely to be hospitalized within the first 24 months after the initiation of treatment. Moreover, subjects treated with RLAI experienced significant improvements in their illness severity and functioning. Discontinuation rates for RLAI were low and doses were stable throughout the 24 months following the initiation of treatment. In addition, the necessity for supplementary concomitant medication was reduced. Adverse events were reported in 20.3% (RLAI) and 11.4% (OA) of the subjects. In general, patients initiated on RLAI and OA at baseline both clinically improved on all assessed parameters but a larger improvement was observed for patients on RLAI. Incidences of reported AEs during the use of RLAI in a naturalistic setting are comparable with those described in clinical studies;however, the incidence of extrapyramidal signs and weight gain was lower than expected.
