All around the world, natural disasters have an impact on both human and animal life. In addition to causing major harm to property, animal life, etc. Natural disasters (including landslides, cloudbursts, heat waves, hurricanes, tsunamis, floods, tsunamis, earthquakes, and wildfires) affect thousands of lives each year throughout the world. Twitter, a social networking platform, users can share news, opinions, and personal stories. Due to the widespread availability of real-time data, numerous service agencies regularly analyze this data to spot crises, lower risk, and save lives. Humans, however, are unable to manually filter through the vast number of records and spot hazards in real-time to achieve this, it has been suggested in numerous studies to provide words in forms that computers can understand and on the word representations, use machine learning techniques to determine the meaning behind a post with accuracy. The community can monitor disasters by reporting hazards that are related to disaster occurrences on social media, which has been essential to emergency preparedness. This study examines how social media platform Twitter might be used in disaster-related research. It focuses on the most recent machine learning, deep learning, and disaster prediction techniques. Acquiring a thorough grasp of the numerous data kinds and their sources in relation to a variety of tasks and crisis management scenarios is another goal of the work. Additionally, The study also aims to offer a comprehensive analysis of the various data mining methods utilized for tackling various issues related to natural disasters as well as comprehensive directions on how to categorize tweets as "Related to Catastrophe" or "Not related with Catastrophe" using natural processing methods.

Acute coronary syndrome (ACS) is a pathology that annually leads to the death of thousands of people around the world. Every year new statistics emerge, and every year they get worse on the global stage. Thus, the following question was asked: "what would be the role of the nurse in the face of a victim with acute coronary syndrome in the emergency department?" That is why the objective of this study was to describe the performance of nurses in a qualified way in the face of the clinical manifestations of Acute Coronary Syndrome. In view of the severity of the pathology and the high rate of morbidity and mortality, further studies on the subject are extremely relevant to better instruct professionals and disseminate the new protocols for the care of these patients. To do this, we chose to use the methodology in the form of an integrative review, to which throughout the research we came across a total of 35 articles talking about this theme. From this number, we excluded 16 because they were outdated and used 19 to carry out this work. We conclude that good care provided in the emergency room quickly and effectively significantly increases the chances of patient survival and, therefore, we can affirm that the initial approach with emphasis on the prevention of lesions secondary to ischemic myocardial injury is extremely important. Therefore, the health professional should be aware of the signs of poor tissue perfusion, thus preventing these secondary lesions.

Endometrial cancer is increasing in prevalence worldwide. It is treated with chemotherapy and radiotherapy, in addition to surgery, but the presence of treatment-resistant tumor cells remains a barrier to effective tumor control. The purpose of this study was to develop drug-resistant cell lines using triciribine, an AKT inhibitor, and investigate the mechanism of acquired resistance. Triciribine sensitivity assays were performed using Cell Counting Kit-8 (CCK-8) on eight endometrial cancer cell lines. The chosen cell lines were highly sensitive to chemotherapy and radiotherapy. A new triciribine-resistant cell line was established and found to be highly resistant to chemotherapy. Properties of the resistant cell line were identified using molecular and cell biological techniques including CCK-8 and quantitative PCR analysis. HEC-151 had the highest triciribine sensitivity (IC50 value of 0.7±0.1 μM) of the endometrial cancer cell lines tested. We established a triciribine-resistant cell line from HEC-151 by growing cells in the presence of increasing concentrations of triciribine up to 66.6 μM. The resistant HEC-151 cells changed to spindle-shaped morphology and importantly reduced triciribine sensitivity compared to the parental cell line. ABC transporters involved in drug efflux had significantly higher expression levels in ABCB1 (1.4±0.10 times higher), ABCC1 (11.4±0.22 times higher), and ABCC4 (4.5±0.42 times higher). In this study, we established a triciribine-resistant cell line from HEC-151 cells. Our data suggest that the mechanism of drug resistance in endometrial cancer cells is attributed to the increased expression of ABC transporters.

Non-invasive Positive Pressure Ventilation (NPPV), an artificial respiration therapy, is a treatment that attaches a mask to the patient’s face and delivers gas into the mask to support breathing. The NPPV mask straps are tensioned so that the supplied gas in the mask does not leak. However, leakage of the gas occurs when the mask strap tension is unbalanced or too weak, while ulcers are caused when the tension is too strong. However, there has been no technical method to know the strength and the balance of the strap tensions quantitatively in NPPV mask fitting.

On the basis of the similarities in the structure of cartilage and intervertebral disc and on the property of glucosamine of being the building block for the construction of proteoglycan aggregates, we investigated the compound's role in the proliferation of nucleus pulposus cells under iso- and hyperosmotic conditions, the putative activation of signaling cascades, and the induction of glycosaminoglycan production. We examined the mode of action of glucosamine in nucleus pulposus cells. Glucosamine that naturally occurs in cartilage tissues has been widely used for treating osteoarthritis, but its role in nucleus pulposus cells is largely unknown. The effect of glucosamine sulfate on the viability and proliferation of nucleus pulposus cells was assessed by the microculture tetrazolium test (MTT) assay, direct cell counting, and tritiated thymidine incorporation. Changes in the expression and phosphorylation profile of selected proteins were estimated by Western analysis. Glycosaminoglycan production was measured using the Blyscan assay. We showed that glucosamine sulfate up to 1 mM did not influence the viability, proliferation rate, or novel DNA synthesis of nucleus pulposus cells in the presence or absence of elevated osmolality but induced the transient phosphorylation of p38 mitogen-activated protein kinase. The highest concentration used (10 mM) negatively affected cellular proliferation and resulted in deactivation of extracellular signal-regulated kinases and c-Jun N-terminal kinases. Interestingly, these effects resulted from an additional hyperosmotic stress provoked by glucosamine alone. Finally, we found that a long-term incubation with glucosamine leads to an increase in the glycosaminoglycan content of nucleus pulposus cells. Glucosamine sulfate was not found to reverse the high osmolality-mediated delay of proliferation in nucleus pulposus cells needed for the maintenance of the tissue's homeostasis. In addition, glycosaminoglycan synthesis stimulated by glucosamine provides a possible promising clinical role for treating disc degenerative disorders.

Randomized, controlled study in a laboratory setting. Blinded observations/assessment of study outcomes. The purpose of this study was to determine the performance characteristics of MASTERGRAFT PUTTY as a bone graft extender in a rabbit posterolateral spine fusion model. The rabbit posterolateral fusion model is an established environment for testing of fusion concepts. It offers the opportunity to obtain radiographical, histological, and biomechanical data on novel fusion materials. Thirty-six rabbits were entered into the study with 30 used for analysis. Bilateral posterolateral lumbar intertransverse fusions were performed at L5-L6. The lateral two-thirds of the transverse processes were decorticated and covered with graft material: autograft only (2.5-3.0 cc per side), 25% MASTERGRAFT PUTTY/75% autograft (3.0 cc total per side), or 50% MASTERGRAFT PUTTY and 50% autograft (3.0 cc total per side). Animals were humanely killed at 8 weeks postsurgery. The autograft group had a 63% radiographical fusion rate (5 of 8) and correlated with manual palpation results (63%). The 25% MASTERGRAFT PUTTY group had a 73% radiographical fusion rate (8 of 11) and a manual palpation fusion rate of 64%. The 50% MASTERGRAFT PUTTY group demonstrated a 91% (10 of 11) radiographical fusion rate and 73% manual palpation fusion rate. Histologically, no inflammatory reactions were evident regardless of implant. The 2 MASTERGRAFT PUTTY groups had new bone in direct apposition to the MASTERGRAFT ceramic granules. In this commonly used rabbit posterolateral fusion model, MASTERGRAFT PUTTY in an autograft extender mode produces clinically and radiographically similar results to autograft fusion alone.

Preclinical feasibility study. Evaluation and validation of ultrasound-guided lumbar transforaminal injections. Lumbar transforaminal injections are routinely implemented in the interventional management of spinal radicular pain. Typically, these injections are administered under fluoroscopy or computed tomography. Although radiological guidance provides anatomical precision and accuracy, it is associated with radiation exposure and cannot be performed during outpatient visits or at bedside. Ultrasound-guided techniques have been previously described; however, the methodological generalizability remained unknown and validation against routine fluoroscopy has never been conducted on multiple spinal levels. We addressed the procedural accuracy of ultrasound-guided lumbar transforaminal injections and proposed anatomically sound approach. Fluoroscopic validation was performed. Of the 50 planned injections, 46 procedures were performed. L5/S1 foraminal access was impossible in 4 cases (8%). Fluoroscopy confirmed the correct foraminal placement in all 46 injections (100%). The contrast-spread pattern was intraforaminal in 42 cases (91.3%) and extraforaminal (nerve root) in 4 cases (8.7%). When intraforaminal pattern was detected on anteroposterior image, lateral fluoroscopy demonstrated ventral epidural flow in all occasions. In 3 cases, intravascular injection was detected (6.5%). Ultrasound-guided lumbar transforaminal injections are accurate and feasible in the preclinical setting.

Cylindrical cages and pedicle screw fixation (PSF) have been used for the setting of a lumbar interbody fusion. To investigate the effects of PSF-nut loosening on lumbar interbody fusion based on the elasto-plateau plasticity of bone characteristics. The stress-strain curves of bone materials beneath the cages show linear elastic behavior before yielding and then seem to be plateau plastic deformation with further compression strain until opposing cell walls contact. Cancellous bone was assumed to be linearly elastic followed by nonlinearly plastic such as crushable foam behavior. The deformation and failure processes caused by loosening of PSF-nuts, in particular, are addressed by means of finite element analysis. Two finite element models, including anterior (or posterior) lumbar interbody fusion for the human lumbar L4-L5 segments, were constructed. In the respective models, 2 types of PSF were considered such as a solid PSF without relative movement between rod and screw, and a tightened PSF with relative axial movement of the rod between them due to the slight loosening of 2 nuts of L4. The slight loosening of nuts showed much greater levels of bone strain with relative motion at the bone-implant interface compared with the PSF with firmly tightened nuts. The loosening 2 of the 4 nuts imposed an excessive burden on the remaining screws. By the consideration of the elasto-plateau plastic behavior of cancellous bone and the relative motion at the contact interface between screw and rod, much more exact behaviors of bone failure were predicted. Slight loosening of the nut would cause a possible risk of segmental instability. With difficulty in either tightening the nut firmly during actual operation or keeping the nut-locking mechanism functioning perfectly in the postoperative state, an enhanced design methodology with more effective locking mechanism is required. Slight PSF-nut loosening may increase risks of failure processes such as rod migration, rod breakage, screw breakage, screw loosening or cage loosening. Different mechanisms however, can be considered; rod breakage and screw breakages are related to the higher stress level of the rod and screw while rod migration is associated with slight nut-loosening. Especially, in the case of a nonsymmetric nut-loosening the risk would be increased. Thus, further study is necessary for improving the current design of PSFs.

A "randomized"/stratified, single-blinded, parallel-group study. OBJECTIVE.: To evaluate 3 structurally different mattresses relative influence on patients with chronic low back pain (CLBP). In several advertisements, it is proclaimed that certain mattresses have a positive effect on LBP, and especially a hard mattress is commonly believed to have a positive effect. One hundred sixty CLBP patients were randomized to 1 of 3 groups, having a mattress/bed mounted in their sleeping room for 1 month. The beds were: (1) waterbed (Akva), (2) body-conforming foam mattress (Tempur), and (3) a hard mattress (Innovation Futon). At baseline and after 4 weeks, a blinded observer interviewed the patients on LBP levels (0-10), daily function (activities of daily living, 0-30), and on the amount of sleeping hours/night. Because of dropout of 19 patients before baseline, the analyses were performed on 141 patients. During the 1-month trial period another 27 patients stopped ahead of time, which were accounted for by "worse case" as well as "no-change" analyses. Both the waterbed and the foam mattress seemed superior to the hard mattress, especially when using the probably most relevant "worst case" data. There were no relevant difference between the effects of the water bed and the foam bed. The Waterbed and foam mattress' did influence back symptoms, function and sleep more positively as apposed to the hard mattress, but the differences were small.

Descriptive review. To describe the role of pay-for-performance as a health care policy that has a significant influence on the management of spinal disorders, and to consider parameters of quality measure that are likely to optimize the efficacy of a pay-for-performance system as applied to spine care. Pay-for-performance arrangements have been adopted in many areas of medicine with limited evidence for improvement in quality of care. There is an important role for a system that will improve quality of care in the management of spinal disorders. The absence of accepted evidence-based approaches to the management of spinal disorders makes the choice of parameters to measure for quality difficult. Performance parameters to consider include a continuum of measures from process variables that focus on a discrete component of the health care experience, to outcome variables that encompass the end result of care. There are advantages and limitations to each parameter discussed. A pay-for-performance system in the management of spinal disorders should include both process variables that measure safety and outcome variables that reflect the end result of care.
