We aimed to evaluate emergency vascular complications of the lumbar disc reconstructive surgery in this study.

Between March 2006 and February 2020, nine patients (six males and three females; mean age 53.4 ± 9.6 years; range 38-64 years) who underwent emergent vascular intervention during lumbar spinal disc reconstructive surgery in our clinic were included in this retrospective study.

The left common iliac artery injury, the left common iliac artery and left common iliac vein injuries, bilateral common iliac artery and abdominal aortic injuries, and vena cava inferior injury with left common iliac vein and right common iliac vein injuries were detected in two, three, two, and two patients, respectively. In addition, 16 mm Dacron tube graft interposition and graft patch plasty were performed in one and two patients who had an abdominal aortic injury, respectively. read more Also, 8 mm polytetrafluoroethylene straight graft interposition was performed in two patients with left common iliac artery injury, and lateral wall repair was performed in other patients. Graft patch plasty and 8 mm polytetrafluoroethylene graft interposition were performed in one patient with vena cava inferior injury and left common iliac vein injury, respectively. Also, lateral wall repair was performed in other patients with venous injuries. Deep venous thrombosis had developed in three patients, and one patient of these had a pulmonary embolism.

The incidence of vascular injury after the lumbar disc surgery is relatively low; however, the emergency vascular operation should be performed as soon as possible.

In order to investigate the molecular mechanisms of air pollution-induced CVDs toxicity, human umbilical vein endothelial cells (HUVECs) were exposed to PM2.5 collected from January, 2016 winter in Beijing, China. We performed RNA sequencing to elucidate key molecular mechanism of PM 2.5-mediated toxicity in HUVECs. A total of 1753 genes, 864 up-regulated and 889 down-regulated, were observed to be differentially expressed genes (DEGs). Among these, genes involved in metabolic response, oxidative stress, inflammatory response, and vascular dysfunction were significantly differentially expressed (log2 FC > 4). The results were validated by quantitative real-time PCR (qPCR) and Western blot for CYP1B1, HMOX1, IL8, and GJA4. Pathway analysis revealed that DEGs were involved in the biological processes related to metabolism, inflammation, and host defense against environmental insults. This research is providing a further understanding of the mechanisms underlying PM2.5-induced cardiovascular diseases (CVDs).Human-Robot Collaboration (HRC) has been widely used in daily life and industry for maximizing the advantages of humans and robots, respectively. However, the internal modeling errors or external perturbations still affect robotic systems such as human collisions and environmental changes. Multimodal anomaly detection plays an increasingly important role in HRC applications, which detects unexpected anomalies from multimodal signals. Due to the complex temporal dependence and stochasticity, it is still difficult to choose a common model applicable to all collaborative tasks, and lack of comparative analysis of existing methods and verification of specific application cases. In this paper, six representative deep learning-based methods are evaluated and the comparing metrics including detection accuracy, multi-modality combinations, and anomaly time bias. For a fair comparison, each detector models multimodal signals from non-anomalous samples and then determines an anomaly using a predefined threshold. We evaluate the detectors with force, torque, velocity, tactile, and kinematic sensing during a human-robot kitting experiment that consists of six individual skills, results indicate that the LSTM-DAGMM based detector outperformed the others, which yielding higher accuracy and efficiency. The metrics are measured with the RUC and ROC by changing the settings of multi-modality combinations and various anomaly biases, which aim to obtain the best performance of multimodal anomaly detection.Reactions in leprosy are acute inflammatory episodes that can be classified as type I or type II. Recognition and timely management of these patients is critical to avoid permanent disability. We present two cases of erythema nodosum leprosum, presenting with recurrent atypical features, responding well to a low dose of methotrexate.In this study, we attempted to move beyond the skewed discussions on stigma to unravel other social consequences that are experienced by persons who have recovered from COVID-19. We conducted a documentary review of published news reports from 14 highly ranked news portals in Ghana and Malaysia (published between 1st January 2020 and 30th August 2020) that contained personal accounts from the recovered patients about their lived experiences with the virus and social consequences encountered after recovery. Narratives from the recovered patients were extracted and analyzed following the narrative thematic analysis procedure. Common themes identified from the narratives included 1) Stigma impacting mental health, 2) Assault and abuse 3) Experiences of treatment. The findings show the need for interprofessional collaboration between social and health care professionals such as social workers, community health workers, medical practitioners and psychologists to prevent and address issues of abuse and other social consequences experienced by COVID-19 survivors.Bioprinting is a technique that has been applied in the areas of tissue engineering and regenerative medicine (TERM). Natural polymer-based hydrogels are known for their favorable biocompatible properties, as well as attractive biomaterials for cell encapsulation. These hydrogels provide an aqueous three-dimensional environment with biologically relevant chemical and physical signals, mimicking the natural environment of the extracellular matrix (ECM). Chitosan (CHI) and hyaluronic acid (HA) have been widely researched for biomedical applications. Bioinks are "ink" formulations, usually hydrogels, that allow the printing of living cells. This work proposes the development of a low cost and simple chitosan CHI-AH hydrogel with potential to become a bioink. At physiological temperature, the biomaterials form a hydrogel. The material developed was characterized by the analysis of morphology, cytotoxicity, and cell viability. FTIR showed the characteristic vibrational bands of chitosan and HA. No difference in swelling was observed between the different formulations studied, although SEM showed architectural differences between the hydrogels obtained.
